DETAILED DESCRIPTION

[0055]Technical solutions in the present disclosure will be clearly and fully described with reference to the accompanying drawings in the present disclosure.

[0056]A cleaning device such as a sweeping robot is configured to clean a surface. After cleaning, the sweeping robot can be stored in a base station and charged by the base station. In the related art, because the function of the base station is relatively limited, a usage rate of the sweeping robot and the base station by a user is relatively low.

[0057]Aiming at the above problem, the disclosure describes a base station including a base and a wet cleaner (e.g., a portable cleaning device, a mopping device) detachably installed on the base. A wet cleaner can clean a surface such as a floor, a carpet, or a couch, by spraying water or mopping with, for example, a damp cloth. When the wet cleaner is installed on the base, the base station is configured to support the wet cleaner. The wet cleaner is configured to clean a surface alone, and the base station can also be configured to dock a cleaning device, to increase use scenarios of the base station and improve a usage rate of the base station, the wet cleaner and the cleaning device.

[0058]Referring to FIG. 1, FIG. 2, and FIG. 3, a base station 100 in the disclosure can be used in a robot system which can include the base station 100 and a cleaning device 200. When the cleaning device 200 is docked on the base 10, the base station 100 is configured to supply power to the cleaning device 200. Additionally, the base station 100 is also configured to clean functional components of the cleaning device 200.

[0059]Referring to FIG. 2, in some examples, the cleaning device 200 may have a sewage container 210. The sewage container 210 may be a cavity structure on the cleaning device 200. In some examples, during the cleaning of the surface by the cleaning device 200, the sewage container 210 is configured to contain sewage collected and generated during the cleaning of the cleaning device 200. For example, the sewage container 210 may be a tank fixedly installed on the cleaning device 200 and configured to store water or a tank detachably installed on the cleaning device 200. The sewage container 210 may be a cavity part integrally formed with a housing of the cleaning device 200 and configured to store water.

[0060]In some examples, the cleaning device 200 has a dust collecting box 230 which can collect solid waste on the surface.

[0061]In some examples, the cleaning device 200 has a clean water container 220 which is configured to contain clean water, and the clean water container 220 is configured to deliver clean water to preset parts such as rags of the cleaning device 200, so that the preset parts can clean the surface after soaking, or directly sprinkle water on the surface.

[0062]In some examples, the cleaning device 200 has a first power module 240 which may be a battery module with a battery or a combination of a battery module with a charging and discharging function and a charging circuit. For example, the first power module 240 in this example may be a combination of a wired charging circuit and a battery module, or a combination of a wireless charging circuit and a battery.

[0063]Referring to FIG. 3 to FIG. 11, the disclosure describes an example of the base station 100 configured to dock the cleaning device 200. The base station 100 includes the base 10 and a wet cleaner 20. The base 10 is configured to dock the cleaning device 200. The wet cleaner 20 is configured to clean a surface and is detachably installed on the base 10.

[0064]The base 10 can be placed in a preset position. The base 10 can be configured to dock the cleaning device 200, which means that the cleaning device 200 can be parked at a preset position on the base 10. When the cleaning device 200 is docked on the base 10 in an example of the disclosure, the cleaning device 200 can fit the preset position of the base 10. The cleaning device 200 can fit the base 10 by contact or non-contact. The cleaning device 200 can directly abut against, adhere to or plug in the preset position of the base 10 under the contact fit, and there may be a certain gap between the cleaning device 200 and the base 10 under the non-contact fit. For example, the preset position can be a structure on the base 10 that can be electrically connected with the cleaning device 200, so that the base can be used for charging the cleaning device 200. For example, the preset position can also be a structure on the base 10 that can contact-fit at least one of a roller, the bottom wall, the side wall and the top wall of the cleaning device 200. In some examples, the base 10 is provided with a docking part 11, which can be used for placing or supporting the cleaning device 200. The docking part 11 can be a cavity recessed on the base 10 or a base structure connected to the base 10. In some examples, the base 10 can be in non-contact fit with the cleaning device 200 and can wirelessly charge the cleaning device 200.

[0065]Referring to FIGS. 5 to 9, in some examples, the base station 100 further includes a dust collecting part 14 having a dust collecting bin 143 and an air inlet port 141 and an air outlet port 142 separately communicating with the dust collecting bin 143. The dust collecting part 14 can be fixedly or detachably connected to the base station 100.

[0066]The dust collecting part 14 can be a hard box-shaped structure or a bag-shaped structure with deformable performance, and the dust collecting part 14 can also be a combination of a hard box-shaped structure and a deformable bag-shaped structure.

[0067]The dust collecting part 14 is at least partially hollow, and a dust collecting bin 143 is formed in a hollow part inside the dust collecting part 14. The air inlet port 141 and the air outlet port 142 communicate with the dust collecting bin 143, so that air flow can enter the dust collecting bin 143 from the air inlet port 141 and flow out of the air outlet port 142. For example, the dust collecting part 14 can also be connected with a pipeline, the pipeline can form a dust outlet duct 144, and an end of the pipeline away from the dust collecting part 14 can form the air inlet port 141. The air outlet port 142 can be connected with a device with negative pressure function, and dust can be sucked into the dust collecting bin 143 from the air inlet port 141 by forming negative pressure at the air outlet port 142. For example, a negative pressure device can also be connected to the air inlet port 141 to form negative pressure at the air inlet port 141, so as to pump garbage such as dust and debris from the air inlet port 141 into the dust collecting bin 143. In some examples, the air inlet port 141 can be configured to connect with the dust collecting box 230 of the cleaning device 200 when the cleaning device 200 is docked on the base 10, so as to suck the dust in the cleaning device 200 into the dust collecting part 14, thereby cleaning the dust collecting box 230 of the cleaning device 200. For example, in this example, a device with negative pressure function can be provided on the cleaning device 200, and the dust in the dust collecting box of the cleaning device 200 can be pumped into the dust collecting bin 143 through the device with negative pressure function. In some examples, the base station 100 is provided with an air duct port 192 communicating with the air outlet port 142, and the air duct port 192 can be connected with the device with negative pressure function, so as to form a negative pressure environment in the dust collecting part 14 and facilitate dust to enter the dust collecting bin 143 under the action of negative pressure.

[0068]In some examples, the dust collecting part 14 includes a dust bag, and the dust bag can be configured to house solid impurities such as dust and can be installed inside the dust collecting bin 143, so as to collect the solid impurities entering the dust collecting bin 143. For example, the dust bag can also be installed at the air inlet port 141 or the air outlet port 142 of the dust collecting part 141. When the dust bag bulges under the action of wind, the outer contour of the dust bag can be generally cylindrical. Taking the dust bag provided inside the dust collecting bin 143 as an example, when airflow enters the dust collecting bin 143 from the air inlet port 141, the dust in the airflow can be blocked in the dust bag, and the dust bag can collect solid impurities in the airflow to purify the airflow. The purified airflow can be output from the air outlet port 142, and the user can open the dust collecting part 14 to clean or replace the dust bag when necessary.

[0069]Referring to FIG. 9, FIG. 10 and FIG. 11, the wet cleaner 20 is detachably installed on the base 10, and is configured to clean the surface. The wet cleaner 20 is configured to clean the surface, such as the floor, carpet, sofa, and mattress. The wet cleaner 20 is detachably mounted on the base 10, which means that the wet cleaner 20 can be detached from the base 10 and used for cleaning the surface alone, and the wet cleaner 20 can also be mounted on the base 10.

[0070]When the wet cleaner 20 is mounted on the base 10, the wet cleaner 20 is disposed adjacent to the dust collecting part 14. Disposing the wet cleaner 20 adjacent to the dust collecting part 14 means that the wet cleaner 20 can be fitted to the outer side of the dust collecting part 14, or the wet cleaner 20 can be disposed on the base 10 close to and side by side with the dust collecting part 14. In this example, the wet cleaner 20 is disposed adjacent to the dust collecting part 14, which can make the structure of the base station 100 relatively more compact and reduce space waste on the base station 100.

[0071]Referring to FIG. 8 to FIG. 15, the water tank assembly 1001 (also called water tank) is configured to store water. The water tank assembly 1001 in an example of the disclosure can be used for storing sewage and a clean water source. The sewage may be sewage on the surface or sewage on the base 10. The clean water source may be clean water or a mixture of clean water and a cleaning liquid. In this example, at least two cavities can be formed on the water tank assembly 1001 to separate and form areas for storing sewage and water source. In some examples, the water tank assembly 1001 may further include a liquid storage tank 257 configured to store a cleaning liquid.

[0072]The power assembly 1003 is configured to provide power to suck sewage into the water tank assembly 1001, or provide power to output the water source of the water tank assembly 1001 to a preset position, or output a cleaning liquid of the liquid storage tank 257 to a preset position. For example, the water tank assembly 1001 includes a first sewage tank 21, and the power assembly 1003 in this example may include a fan 215. The fan 215 may be configured to suck the sewage on the surface or the sewage on the base 10 into the first sewage tank 21, or suck the sewage in the first sewage tank 21 into a second sewage tank 30. For example, the water tank assembly 1001 includes a first clean water tank 22, and the power assembly 1003 in the example of the disclosure may include a water pump 23 which may be configured to output water in the first clean water tank 22 to the surface or the base 10. The power assembly 1003 may also be configured to output the clean water in the second clean water tank 40 to a preset position on the base 10. For example, the power assembly 1003 may also be configured to be connected to the dust collecting part 14. When the cleaning device 200 is docked on the base 10, the power assembly 1003 may also be configured to generate negative pressure on the dust collecting part 14 to suck (e.g., draw in, collect, intake) the dirt in the dust collecting box 230 of the cleaning device 200 into the dust collecting part 14.

[0073]Referring to FIG. 12 to FIG. 18, in some examples, the water tank assembly 1001 includes the first sewage tank 21 and a sewage recovery pipeline 242 communicating with the first sewage tank 21, and the power assembly 1003 can be configured to suck the sewage on the surface into the first sewage tank 21. The first sewage tank 21 can be used for containing sewage. The first sewage tank 21 has a sewage cavity 218 and a sewage inlet 211 and an air outlet 214 which communicate with the sewage cavity 218. The first sewage tank 21 can be used as a mechanism for storing sewage on the wet cleaner 20. The first sewage tank 21 is at least partially hollow to form a sewage cavity 218 for storing sewage. The first sewage tank 21 further has the sewage inlet 211 and the air outlet 214 which communicate with the sewage cavity 218. The sewage inlet 211 may be configured for sewage to enter the sewage cavity 218, and the air outlet 214 may be configured to communicate with the power assembly 1003.

[0074]In some examples, the water tank assembly 1001 includes a first clean water tank 22 and a water supply pipe 243 connected to the first clean water tank 22, and the power assembly 1003 can be configured to provide negative pressure to transport water in the first clean water tank 22 to the surface through the water supply pipe 243.

[0075]In some examples, the wet cleaner 20 includes a second power module 26, and the wet cleaner 20 also includes an external power line which can be used for connecting to commercial power or charging the second power module 26.

[0076]Referring to FIG. 15, in some examples, the second power module 26 includes a main control board 28, which can be configured to control a working state of the wet cleaner 20 and can be a circuit board or an integrated board. An electronic control box 281 for accommodating the main control board 28 can be disposed in a housing 29.

[0077]Referring to FIGS. 10 and 14, in some examples, the wet cleaner 20 includes a washer 24 which can be configured to clean a surface.

[0078]In some examples, the wet cleaner 20 further includes a sewage recovery pipeline 242 which can be connected to the washer 24 and configured to suck the sewage on the surface. In this example, clean water, a cleaning liquid, or a mixed solution of clean water and a cleaning liquid can be sprayed on the surface in advance. Sewage is generated when the washer 24 cleans the surface, and an inlet of the sewage recovery pipeline 242 may be disposed close to the washer 24, so as to suck the sewage generated at the washer 24 to a preset position. The sewage recovery pipeline 242 can be a water pass formed by a hose or a pass formed by combining a hose and a rigid tubular structure.

[0079]The washer 24 in the example of this disclosure may have a brush head 241. The brush head 241 can be configured to brush the surface. The brush head 241 may be a brush, a rubber brush or a combination of a brush and a rubber brush. In some examples, the wet cleaner 20 may comprise a cloth washer, which may be configured to clean cloth surfaces. The cloth washer can have a cleaning function and can also have at least one of functions such as negative pressure suction and drying.

[0080]Referring to FIGS. 1 to 12, in some examples, the cleaning device 200 includes a dust collecting box 230 for collecting swept garbage. The base station 100 includes a base 10, a dust collecting part 14 and a wet cleaner 20. The base 10 is provided with a first pipeline assembly 1002. The dust collecting part 14 is disposed above the base 10 to communicate with the dust collecting box 230 when the cleaning device 200 is docked with the base 10. The wet cleaner 20 is detachably disposed above the base 10. The wet cleaner 20 includes a power assembly 1003, a water tank assembly 1001 and a second pipeline assembly 202 communicating with the water tank assembly 1001. The wet cleaner 20 has at least a first mode and a second mode. In the first mode, the wet cleaner 20 is located above the base 10 and at a side of the dust collecting part 14, and the second pipeline assembly 202 communicates with the first pipeline assembly 1002. The power assembly 1003 is configured to drive water to enter or exit the water tank assembly 1001 through the first pipeline assembly 1002 and the second pipeline assembly 202. In the second mode, the wet cleaner 20 is configured to clean the surface.

[0081]In this example, when the wet cleaner 20 is installed on the base 10, the wet cleaner 20 is located at a side of the dust collecting part 14, so that the wet cleaner 20 can use the space beside the dust collecting part 14, which is conducive to improving compactness of the base station 100. For example, the wet cleaner 20 and the dust collecting part 14 may both be disposed above the base 10.

[0082]The second pipeline assembly 202 is configured to connect the first pipeline assembly 1002, so that the second pipeline assembly 202 and the first pipeline assembly 1002 can form a flow channel for liquid to flow between the base 10 and the wet cleaner 20. The first pipeline assembly 1002 may be a passage formed by a pipeline disposed on the base station 100. For example, the first pipeline assembly 1002 may be a passage formed by a hollow area where functional components on the base station 100 are molded. The number of the first pipeline assemblies 1002 in this example may be one or more, and the liquid paths of the first pipeline assemblies 1002 may be formed in the same way or different ways. For example, the first pipeline assembly 1002 can be configured to form a passage for sewage to flow. When negative pressure is generated on the first pipeline assembly 1002 by a negative pressure device, sewage can flow in a preset direction along the first pipeline assembly 1002. For example, the first pipeline assembly 1002 can be configured to form a channel for the clean water to flow. Water can be transported into the first pipeline assembly 1002 by a pressurized apparatus, so that the clean water can flow in a preset direction along the first pipeline assembly 1002.

[0083]The wet cleaner 20 has multiple modes, including a first mode and a second mode. In the first mode, the power assembly 1003 can be configured to provide power to drive water to enter or exit the water tank assembly 1001 through the first pipeline assembly 1002 and the second pipeline assembly 202. In this example, the power assembly 1003 can be configured to cause water to enter the wet cleaner 20 through the first pipeline assembly 1002 and the second pipeline assembly 202 in turn, and can also be configured to cause water to enter the base 10 through the second pipeline assembly 202 and the first pipeline assembly 1002 in turn. In the second mode, the wet cleaner 20 can be configured to clean the surface. At this time, the wet cleaner 20 can be detached from the base 10, so that the wet cleaner 20 can be used alone. It can be understood that the wet cleaner 20 can also have other operating modes, such as a heating mode and a drying mode, which is not described in detail.

[0084]Referring to FIG. 9, in some examples, the installation recess 16 is recessed on the base 10. When the wet cleaner 20 is installed on the base 10, the wet cleaner 20 is partially placed in the installation recess 16. The installation recess 16 is a recessed part disposed on the wet cleaner 20. For example, the base station 100 may have a first wall 19, and the installation recess 16 may be a recess formed on the first wall 19. For example, the base station 100 may include at least one of the dust collecting part 14, the second sewage tank 30 and the third sewage tank in any of the above examples, and the installation recess 16 may be located at the side of the dust collecting part 14, the second sewage tank 30 or the third sewage tank. In this example, by providing the installation recess 16, when the wet cleaner 20 is installed on the base 10, the wet cleaner 20 can be accommodated on the base 10, so that the wet cleaner 20 and the base 10 can fit each other, which can improve the stability of the wet cleaner 20 on one hand and make full use of the space on the base 10 on the other hand.

[0085]In some examples, the dust collecting part 14 may at least partially protrude toward the outside of the first wall 19, so that there is a height difference between the dust collecting part 14 and the first wall 19. An area formed by the height difference between the dust collecting part 14 and the first wall 19 can form the installation recess 16.

[0086]In some examples, when the wet cleaner 20 is installed on the base 10, the dust collecting part 14 and the wet cleaner 20 are arranged side by side on a horizontal plane. For example, lower ends of the dust collecting part 14 and the wet cleaner 20 can be set at the same height, so as to facilitate placing the dust collecting part 14 and the wet cleaner 20 on a preset plane on the base 10 and facilitate forming and processing of the base 10; for example, the dust collecting part 14 may have the air outlet port 142 according to any of the above examples, and the air outlet port 142 may be disposed on the bottom wall of the dust collecting part 14.

[0087]For example, lower ends of the dust collecting part 14 and the wet cleaner 20 may be set at different heights but are close in height. There may be a certain height difference between the lower ends of the dust collecting part 14 and the wet cleaner 20. For example, the lower end of the dust collecting part 14 is set lower than the lower end of the wet cleaner 20, and the air outlet port 142 may be disposed on the side wall of the dust collecting part 14.

[0088]Referring to FIGS. 4 and 7, in some examples, the base 10 has a first wall 19, and the base station 100 further includes a storage part 17 which is disposed above the base 10 and has an accommodating recess 171. In the first operating mode, the wet cleaner 20 is located above the base 10 and is partially stored in the accommodating recess 171. Taking the wet cleaner 20 having a washer 24 as an example, the accommodating recess 171 can be configured to store the washer 24 of the wet cleaner 20. The storage part 17 can be a box-shaped structure disposed at the outside of the first wall 19, can be used as a storage component on the base station 100, and can be used for storage. The storage part 17 may have an opening communicating with the accommodating recess 171, and the opening may be configured for the wet cleaner 20 to move into or out of the accommodating recess 171, and the opening in the example of the disclosure may be adapted to the shape of the corresponding part of the wet cleaner 20. For example, an opening can be opened on the side wall of the storage part 17, and the wet cleaner 20 can be moved into or out of the accommodating recess 171 from the side. For example, an opening can be opened on the top wall of the storage part 17, and the wet cleaner 20 can be moved into or out of the accommodating recess 171 from the top, in some examples, the base 10 is provided with the installation recess 16 described in any of the above examples, and the opening of the accommodating recess 171 can be disposed on the side of the storage part facing the installation recess 16. The storage part 17 can be fixedly connected to the base 10; for example, the storage part 17 can also be detachably installed on the base 10. When the wet cleaner 20 is removed from the base 10, the storage part 17 can be removed from the base 10 synchronously, and the wet cleaner 20 and the storage part 17 can be moved and placed together.

[0089]Referring to FIG. 4, FIG. 6 and FIG. 7, in some examples, the storage part 17 is located above the dust collecting part 14, and the storage part 17 can be placed above the dust collecting part 14 along a direction 4a in FIG. 4. In this example, the storage part 17 and the dust collecting part 14 may have separate boxes, and for example, the lower end of the storage part 17 and the upper end of the dust collecting part 14 may share one wall surface. Side walls of the storage part 17 and the dust collecting part 14 and the first wall 19 enclose the installation recess 16. On one hand, a larger space can be formed on the base 10 to accommodate the wet cleaner 20; on the other hand, the washer 24 and the winding of the wet cleaner 20 can be conveniently disposed close to the storage part 17, which is convenient for storage together.

[0090]Referring to FIG. 14, in some examples, the storage part 17 and the dust collecting part 14 are disposed side by side on a horizontal plane. For example, lower ends of the dust collecting part 14 and the storage part 17 can be set at the same height, which facilitates placing the dust collecting part 14 and the storage part 17 on a preset plane on the base 10 and facilitates forming and processing of the base 10. For example, the dust collecting part 14 may have the air outlet port 142 according to any of the above examples, and the air outlet port 142 may be disposed on the bottom wall of the dust collecting part 14.

[0091]For example, lower ends of the dust collecting part 14 and the storage part 17 may be set at different heights but are close in height. There may be a certain height difference between the lower ends of the dust collecting part 14 and the storage part 17. For example, the lower end of the dust collecting part 14 is set lower than the lower end of the storage part 17, and the air outlet port 142 may be disposed on the side wall of the dust collecting part 14. The wet cleaner 20 in this example can be placed in the installation recess 16 in a direction 14a in FIG. 14; for example, when the wet cleaner 20 is placed in the installation recess 16, the washer 24 of the wet cleaner 20 may be located in the accommodating recess 171 of the storage part 17.

[0092]Referring to FIGS. 9 and 14, in some examples, the dust collecting part 14 and the storage part 17 may be horizontally disposed side by side on the base 10, or the storage part 17 may be installed above the dust collecting part 14. The wet cleaner 20 has a housing 29. The washer 24 may include a brush head 241 and a connecting pipe 245. One end of the connecting pipe 245 is connected to the brush head 241, and the other end is connected to the housing 29. When the wet cleaner 20 is installed on the base 10, both the brush head 241 and the connecting pipe 245 are stored in the accommodating recess 171. In some examples, a handle is connected between the brush head 241 and the connecting pipe 245.

[0093]The connecting pipe 245 is connected to the brush head 241. The connecting pipe 245 can be configured to support and connect the brush head 241. The connecting pipe 245 can also be configured to form a space for accommodating pipelines which can include cables with communication and/or power supply functions and can also include pipelines for forming the sewage recovery pipeline 242 and pipelines for forming the water supply pipe 243. For example, the connecting pipe 245 can be a round or oval hose, and can also be a corrugated pipe or a combination of hoses with various shapes. The connecting pipe 245 can be a combination of hoses and hard pipes, so as to improve the structural strength of the connecting pipe 245.

[0094]When the wet cleaner 20 is installed on the base 10, both the brush head 241 and the connecting pipe 245 are stored in the accommodating recess 171, so that both the brush head 241 and the connecting pipe 245 can be hidden in the accommodating recess 171, which on one hand can reduce exposure of the brush head 241 and the connecting pipe 245, and on the other hand can reduce interference of the brush head 241 and the connecting pipe 245 with external equipment.

[0095]In some examples, the wet cleaner 20 has a housing 29, and the housing 29 is provided with a protruding column 291 configured to wind a pipeline. When the wet cleaner 20 is installed on the base 10, the protruding column 291 is at least partially stored in the accommodating recess 171.

[0096]The pipeline may include cables with communication and/or power supply functions, a pipeline for forming the sewage recovery pipeline 242 and a pipeline for forming the water supply pipe 243, and a connecting pipe 245 as described in the above example. The protruding column 291 is a protruding structure protruding outside the housing 29. The protruding column 291 can be configured to wind pipelines, which can reduce the problem of messy visual effect caused by pipeline scattering on one hand. On the other hand, when the wet cleaner 20 is installed on the base 10, the protruding column 291 is at least partially stored in the accommodating recess 171, which can facilitate the pipeline and the protruding column 291 to be stored in the accommodating recess 171 together. The protruding column 291 can be a cuboid, a cylinder or a special-shaped structure; for example, the protruding column 291 has a proximal end connected to the housing 29 and a distal end away from the housing 29. The cross-sectional area of the distal end of the protruding column 291 can be larger than that of the proximal end of the protruding column 291, so that the distal end of the protruding column 291 can block the pipeline and reduce the possibility that the pipeline falls off the protruding column 291. In some examples, the washer 24 further includes the brush head 241 described in the above example, and the protruding column 291 can be provided with a slot or a buckle for positioning the brush head 241, and the brush head 241 can be locked on the protruding column 291 when the washer 24 is not needed; when the wet cleaner 20 needs to be installed on the base 10, the brush head 241, the protruding column 291 and the pipeline on the protruding column 291 can be directly stored in the accommodating recess 171 together.

[0097]Referring to FIGS. 12 and 16 to 22, in some examples, the water tank assembly 1001 includes a first sewage tank 21 and a sewage recovery pipeline 242 communicating with the first sewage tank 21, the power assembly 1003 includes a fan 215, the first pipeline assembly 1002 includes a first sewage pipeline 12, and the second pipeline assembly 202 includes a second sewage pipeline 203 communicating with the first sewage tank 21. In the first mode, the first sewage pipeline 12 communicates with the second sewage pipeline 203, and the fan 215 is configured to provide suction to suck the sewage collected by the base 10 into the first sewage tank 21 through the first sewage pipeline 12 and the second sewage pipeline 203 in turn. In the second mode, the fan 215 is configured to suck sewage on the surface into the first sewage tank 21 through the sewage recovery pipeline 242.

[0098]The second sewage pipeline 203 can be used as a channel for connecting the base 10 on the wet cleaner 20, and the first sewage pipeline 12 can be used as a channel for connecting the wet cleaner 20 on the base 10 for sewage to flow between the base 10 and the wet cleaner 20. The fan 215 in this example is used as a power source. In the first mode, the wet cleaner 20 is installed on the base 10, and the first sewage pipeline 12 and the second sewage pipeline 203 are connected with each other. The fan 215 can be configured to suck the sewage on the base 10 into the first sewage tank 21 through the first sewage pipeline 12 and the second sewage pipeline 203 in turn, and thus can collect the sewage on the base 10 on the wet cleaner 20. In the second mode, the first sewage pipeline 12 can be used as a channel for sewage to flow on the wet cleaner 20. When the wet cleaner 20 is used alone, sewage on the surface can enter the first sewage tank 21 through the sewage pipeline.

[0099]In some examples, the base 10 is provided with a washing tank 101 (e.g., a washing groove, a washing slot), and the first sewage pipeline 12 communicates with the washing tank 101. In this example, the first sewage pipeline 12 is connected to the washing tank 101. In the first mode, the wet cleaner 20 can suck the water in the washing tank 101 into the first sewage tank 21 for storage. The washing tank 101 can be a recess recessed on the base 10. When the cleaning device 200 is docked at a preset position on the base 10, wet cleaning components such as rags of the cleaning device 200 can be at least partially located in the washing tank 101, and can clean the cleaning device 200 by inputting water into the washing tank 101. In some examples, the washing tank 101 can also be an area configured to receive the sewage generated when the wet cleaning components are washed. When the cleaning device 200 is docked on the base 200, the wet cleaning components of the cleaning device 200 can be suspended above the washing tank 101, and the wet cleaning components can be cleaned by conveying or spraying water to the wet cleaning components, and the sewage generated during cleaning can be accommodated in the washing tank 101.

[0100]In some examples, the first sewage pipeline 12 is configured to communicate with the sewage container 210 of the cleaning device 200 when the cleaning device 200 is docked with the base 10. In the first mode, when the cleaning device 200 is docked on the base 10, the first sewage pipeline 12 can be used as a connection channel between the cleaning device 200 and the wet cleaner 20, the wet cleaner 20 can be configured to collect sewage in the sewage container 210 of the cleaning device 200 to clean the cleaning device 200.

[0101]In some examples, the base 10 is provided with the washing tank 101, and the first sewage pipeline 12 includes a first main pipeline 123, a first sub-pipeline 124 and a second sub-pipeline 125 which communicate with the first main pipeline 123, the first main pipeline 123 communicates with the second sewage pipeline 203, the first sub-pipeline 124 communicates with the washing tank 101, and the second sub-pipeline 125 is configured to communicate with the sewage container 210 of the cleaning device 200 when the cleaning device 200 is docked with the base 10. In this example, the first sewage pipeline 12 has two branches of the first sub-pipeline 124 and the second sub-pipeline 125, which are respectively configured to connect the washing tank 101 and the cleaning device 200. In this example, the first main pipeline 123, the first sub-pipeline 124 and the second sub-pipeline 125 can adopt a tee branch structure or a flow channel formed by a hollow area on the base 10. In this example, the first main pipeline 123, the first sub-pipeline 124 and the second sub-pipeline 125 are configured to form the first sewage pipeline 12, which can facilitate switching of the two sewage flow channels and reduce difficulty of connection of the washing tank 101 and the cleaning device 200 with the first sewage pipeline 12.

[0102]In some examples, the base 10 is provided with a second sewage tank 30, and the second sewage tank 30 is provided with a third sewage pipeline 31, which communicates with the second sewage pipeline 203 in the first mode. In this example, the second sewage tank 30 can be fixedly or detachably connected to the base 10, and the second sewage tank 30 can be used as an area for storing water on the base 10. The third sewage pipeline 31 is connected to the second sewage tank 30, so that sewage can flow between the second sewage tank 30 and the third sewage pipeline 31. In the first mode, the third sewage pipeline 31 communicates with the second sewage pipeline 203, so that sewage can flow between the third sewage pipeline 31 and the second sewage pipeline 203. In this example, the sewage in the first sewage tank 21 can be collected by negative pressure equipment to the second sewage tank 30 through the second sewage pipeline 203 and the third sewage pipeline 31 in turn, to clean the sewage in the first sewage tank 21 of the wet cleaner 20 when the wet cleaner 20 is installed on the base 10. For example, in the first mode, the fan 215 is configured to provide suction to suck water in the first sewage tank 21 into the second sewage tank 30 through the second sewage pipeline 203 and the third sewage pipeline 31 in turn, and can be used as a power source to make the second sewage tank 30 or the third sewage pipeline 31 in a negative pressure state, so that sewage can flow from the first sewage tank 21 of the wet cleaner 20 into the second sewage tank 30 of the base 10. For example, in the first mode, the wet cleaner 20 is installed on the base 10, and the third sewage pipeline 31 can be directly connected with the second sewage pipeline 203, and the third sewage pipeline 31 can also be indirectly connected with the second sewage pipeline 203. The indirect connection means that the third sewage pipeline 31 can communicate with the second sewage pipeline 203 through valves, pipelines or a combination thereof. For example, in the first mode, the third sewage pipeline 31 is connected with the first sewage pipeline 12, the first sewage pipeline 12 is connected with the second sewage pipeline 203, and the sewage in the first sewage tank 21 can enter the second sewage tank 30 through the second sewage pipeline 203, the first sewage pipeline 12 and the third sewage pipeline 31 in turn.

[0103]Referring to FIG. 13, in some examples, the base 10 is provided with the second sewage tank 30, and the second sewage tank 30 is provided with the third sewage pipeline 31, which is configured to communicate with the sewage container 210 of the cleaning device 200 when the cleaning device 200 is docked with the base 10. The second sewage tank 30 may be configured to collect sewage on the cleaning device 200 when the cleaning device 200 is docked on the base 10. When the cleaning device 200 is docked on the base 10, the sewage in the sewage container 230 of the cleaning device 200 can enter the second sewage tank 30 via the third sewage pipeline 31. For example, a negative pressure device may be provided on the cleaning device 200 or the base 10, and the sewage in the sewage container 230 is sucked into the second sewage tank 30 through the negative pressure device. For example, when the wet cleaner 20 is docked on the base 10, the power assembly 1003 can be connected with the second sewage pipeline 203, and the second sewage pipeline 203 can be connected with the second sewage tank 30, which can form a negative pressure through the power assembly 1003 to suck the sewage in the sewage container 230 of the cleaning device 200 into the second sewage tank 30 via the third sewage pipeline 31.

[0104]Referring to FIGS. 9 and 16 to 22, in some examples, the base 10 has the washing tank 101, and the third sewage pipeline 31 is configured to connect with the washing tank 101. In the first mode, the fan 215 is configured to provide suction to suck the sewage in the washing tank 101 into the second sewage tank 30 through the third sewage pipeline 31. In this example, the third sewage pipeline 31 can be used as a passage between the washing tank 101 and the second water tank. In the first mode, the fan 215 is used as a power source, so that the sewage in the washing tank 101 can be collected into the second sewage tank 30 along the third sewage pipeline 31. In this example, the third sewage pipeline 31 can be alternatively connected with the washing tank 101 or the sewage container 210 of the cleaning device 200, so that the second sewage tank 30 can be used as a mechanism for temporarily storing sewage on the base 10, which is convenient for cleaning the washing tank 101 and the cleaning device 200.

[0105]Referring to FIGS. 13 to 22, in some examples, the base 10 is provided with the second sewage tank 30 and the washing tank 101, and the second sewage tank 30 is provided with the third sewage pipeline 31. The third sewage pipeline 31 includes a third main pipeline 311, and a fifth sub-pipeline 312 and a sixth sub-pipeline 313 communicating with the third main pipeline 311, in which the fifth sub-pipeline 312 is configured to connect with the sewage container 210 of the cleaning device 200 when the cleaning device 200 is docked with the base 10, and the sixth sub-pipeline 313 is connected with the washing tank 101. In the first mode, the third main pipeline 311 is configured to connect the second sewage pipeline 203, the fan 215 is configured to provide suction to suck the sewage in the sewage container 210 of the cleaning device 200 into the second sewage tank 30 through the fifth sub-pipeline 312 and the third main pipeline 311 in turn, and the fan 215 is configured to provide suction to suck the sewage in the washing tank 101 into the second sewage tank 30 through the sixth sub-pipeline 313 and the third main pipeline 311 in turn. In this example, the third sewage pipeline 31 is provided with two branches, one of which is the third main pipeline 311 and the fifth sub-pipeline 312 and can be configured to connect the second sewage tank 30 with the sewage container 210 of the cleaning device 200; the other of which is the third main pipeline 311 and the sixth sub-pipeline 313 and can be configured to connect with the washing tank 101 and the second sewage tank 30, so that the second sewage tank 30 can form two sewage channels separately. In this example, two branches can be started at the same time to recover the sewage from the washing tank 101 and the cleaning device 200 at the same time, or only one branch can be started to recover the sewage as needed.

[0106]Referring to FIGS. 12 and 13, in some examples, the wet cleaner 20 further includes a control valve 2110. In the first mode, the control valve 2110 is configured to control the first sewage tank 21 to be connected with the second sewage pipeline 203 and the first sewage tank 21 to be disconnected from the sewage recovery pipeline 242. In the second mode, the control valve 2110 is configured to control the first sewage tank 21 to be disconnected from the second sewage pipeline 203 and the first sewage tank 21 to be connected with the sewage recovery pipeline 242. The control valve 2110 in this example can be a Y-shaped or T-shaped valve body structure in the above example. When the working state of the control valve 2110 is switched, the control valve 2110 can be switched between the above two water flow channels, and then one of the sewage recovery pipeline 242 and the first sewage pipeline 12 is connected to the first sewage tank 21 to control on-off state of the sewage flow channels.

[0107]In some examples, the wet cleaner 20 further includes a control valve 2110. In the first mode, the control valve 2110 is configured to control the first sewage tank 21 to communicate with the second sewage pipeline 203, and the control valve 2110 is further configured to control the first sewage tank 21 to communicate with the sewage recovery pipeline 242. The control valve 2110 can be used as an intermediate connector among the first sewage tank 21, the second sewage pipeline 203 and the sewage recovery pipeline 242, and can be configured to control an opening degree of a waterway between the second sewage pipeline 203 as well as the sewage recovery pipeline 242 and the first sewage tank 21, so that the sewage in the base 10 and the sewage recovery pipeline 242 can be sucked into the first sewage tank 21 in the first mode; and the wet cleaner 20 can be configured to collect sewage on the surface and the base 10 in the first mode.

[0108]Referring to FIGS. 12 to 22, in some examples, the wet cleaner 20 includes a control valve 2110 having a water outlet 2121 that can communicate with the sewage inlet 211 of the first sewage tank 21. For example, the control valve 2110 may have at least two water flow channels, in which the control valve 2110 has the first sewage interface 2122, and the first sewage interface 2122 may form a water flow channel toward the water outlet 2121; for example, the first sewage interface 2122 may be connected to the sewage recovery pipeline 242. For example, the control valve 2110 has the second sewage interface 2123, which can form another water flow channel toward the water outlet 2121. For example, the second sewage interface 2123 can be configured to connect the first sewage pipeline 12. When the working state of the control valve 2110 is switched, the control valve 2110 can be switched between the above two water flow channels, so that one of the sewage recovery pipeline 242 and the first sewage pipeline 12 is connected to the first sewage tank 21. The control valve 2110 in this example may include a sewage tee branch 212 with a sewage flow channel and the water outlet 2121, the first sewage interface 2122 and the second sewage interface 2123 which communicate with the sewage flow channel; and a sewage control valve 213 which is at least partially disposed in the sewage flow channel of the sewage tee branch 212; and a sewage control valve 213 for controlling at least one of the first sewage interface 2122 and the second sewage interface 2123 to communicate with the water outlet. In this example, the sewage control valve 213 may be mechanically driven or electrically driven, so that the sewage control valve 213 can move relative to the sewage tee branch 212, thereby switching the water flow channel of the sewage tee branch 212. For example, a motor can be disposed outside the sewage tee branch 212, and the sewage control valve 213 is driven by the motor to rotate relative to the sewage tee branch 212, so as to control switching of the water flow channel of the sewage tee branch 212. In this example, the sewage control valves 213 can be installed at a preset position on the sewage tee branch 212 to control the water flow state in the sewage tee branch 212. For example, there may be a plurality of sewage control valves 213, and the sewage control valves 213 can be respectively disposed on the first sewage interface 2122 and the second sewage interface 2123 to control opening and closing states of the first sewage interface 2122 and the second sewage interface 2123 respectively, which respectively may include opening one of the first sewage interface 2122 and the second sewage interface 2123 and closing the other, or controlling the first sewage interface 2122 and the second sewage interface 2123 to be partially opened or fully opened separately through the sewage control valve 213.

[0109]In some examples, the power assembly 1003 includes the fan 215, and the dust collecting part 14 includes the dust collecting bin 143, and the air inlet port 141 and the air outlet port 142 which separately communicate with the dust collecting bin 143, in which the air inlet port 141 is configured to communicate with the dust collecting box 230, and the air outlet port 142 is configured to communicate with an air inlet of the fan 215; in the first mode, the fan 215 is configured to recycle the swept garbage in the dust collecting box 230 into the dust collecting bin 143.

[0110]The dust collecting part 14 is configured to connect the dust collecting box 230 when the cleaning device is docked on the base 10, and the base 10 is provided with an air duct port 192 communicating with the dust collecting part 14. The wet cleaner 20 is provided with an air duct interface 274 connected with the air inlet of the fan 215. When the wet cleaner 20 is installed on the base 10, the air duct interface 274 is connected with the air duct port 192, and the fan 1003 is configured to provide power to suck the dirt in the dust collecting box 230 into the dust collecting part 14. For example, when the wet cleaner 20 is installed on the base 10, the washer 24 is stored in the accommodating recess 171 of the storage part. The accommodating recess 171 in this example can be configured to limit the washer 24. When the wet cleaner 20 is installed on the base 10 and the washer 24 is stored in the accommodating recess 171, the air duct interface 274 and the air duct port 192 are positioned and connected with each other to facilitate fast alignment of the air duct interface 274 with the air duct port 192.

[0111]In some examples, the base 10 is provided with a sewage transfer port 122 and a sewage receiving port 121; the wet cleaner 20 is provided with a sewage interface 272 communicating with the second sewage pipeline 203, and the sewage interface 272 is configured to connect with the sewage transfer port 122 when the washer 24 is stored in the accommodating recess 171. The accommodating recess 171 can be configured to position the washer 24. When the wet cleaner 20 is installed on the base 10 and the washer 24 is stored in the accommodating recess 171, the relative position between the wet cleaner 20 and the base 10 is determined, and at this time, the sewage interface 272 may be positioned and connected with the sewage transfer port 122. In this example, mutual limiting between the accommodating recess 171 and the washer 24 can facilitates connection between the sewage transfer port 122 and the first sewage tank 21, which can facilitate a user's operation and reduce possibility of water leakage.

[0112]Referring to FIGS. 23 and 26, in some examples, the wet cleaner 20 includes a drain three-way valve 216, which includes a drain valve body 2164, a drain valve spool 2163 and a driving module 217. The drain valve body 2164 has a drain flow channel 2165, a drain outlet 2162, a waterway inlet 2161a and an air channel inlet 2161b which separately communicate with the drain flow channel 2165. The air channel inlet 2161b and the waterway inlet 2161a can be respectively used for one-to-one connection to the air outlet port 142 and the sewage transfer port 122, and a drain outlet 2162 can be connected to an inlet of the fan 215. When the fan 215 is started, the fan 215, a drain passage 2167, the air channel inlet 2161b and the dust collecting part 14 can form an air channel, so that negative pressure is formed in the dust collecting part 14. When the cleaning device 200 is docked on the base 10, solid impurities in the dust collecting box of the cleaning device 200 can be sucked into the dust collecting part 14. The fan 215, the drain passage 2167, the waterway inlet 2161a and the first sewage pipeline 12 can also form a waterway to form a negative pressure in the first sewage pipeline 12, and the water in the base 10 can be pumped out through the first sewage pipeline 12. When the cleaning device 200 is docked on the base 10, the temporarily stored sewage in the cleaning device 200 can also be pumped out through the first sewage pipeline 12. In this example, only the air channel or waterway mentioned above can be opened, or the fan 215 can simultaneously communicate with the waterway inlet 2161a and the air channel inlet 2161b to simultaneously extract solid impurities and sewage.

[0113]In some examples, the fan 215 is connected to an end of the sewage recovery pipeline 242 away from the brush head 241. When the fan 215 is started, the fan 215 can form a negative pressure in the sewage recovery pipeline 242 to suck the sewage at the brush head 241 to a preset position. The fan 215 in the example of the disclosure can be configured to suck the sewage in the sewage container 210 when the wet cleaner 20 is installed on the base 10 and the cleaning device 200 is docked on the base 10, so as to clean the cleaning device 200. The fan 215 can also be configured to cooperate with the brush head 241 to suck the sewage on the surface to a preset position when the wet cleaner 20 is used alone, so that two functional modules can share one fan 215, which contributes to simplification of the structure of the base station 100. In this example, the base 10 can only be configured to provide the first sewage pipeline 12. When the cleaning device 200 is docked on the base 10 and the sewage in the sewage container 210 of the cleaning device 200 is sucked, the sewage may not be stored in the base 10, so as to simplify the structure of the base 10, reduce accumulation of pollutants in the base 10, and help to improve sanitary performance of the base 10.

[0114]For example, when the cleaning device 200 is docked on the base 10, the user can choose to pump out the solid impurities in the cleaning device 200 or suck the sewage stored in the cleaning device 200. When negative pressure needs to be formed in the dust collecting part 14, the drain three-way valve 216 can communicate with the dust collecting part 14 and the fan 215, so that the fan 215 can generate negative pressure on the dust collecting part 14, and the solid impurities stored in the dust collecting box 230 of the cleaning device 200 can enter the dust collecting part 14 of the base 10. When the sewage in the sewage container 210 of the cleaning device 200 needs to be pumped out, the driving module 217 can drive the drain valve spool 2163 to rotate relatively, so that the waterway inlet 2161a communicates with the sewage transfer port 122 and the second sewage interface 2123 of the sewage tee branch pipe 212, and the fan 215 can form negative pressure at the air outlet 214, so that the sewage in the sewage container 210 of the cleaning device 200 can be sucked into the first sewage tank 21. When the sewage in the cleaning device 200 does not need to be drained by the wet cleaner 20, the first sewage interface 2122 of the drain three-way valve 216 can communicate with the sewage recovery pipeline 242, and negative pressure is formed in the sewage recovery pipeline 242 by the fan 215 to suck the sewage on the surface into the first sewage tank 21. In some examples, when the driving module 217 can drive the drain valve spool 2163 to rotate relatively, so that the waterway inlet 2161a communicates with the sewage transfer port 122 and the second sewage interface 2123 of the sewage tee branch 212, and when the first sewage interface 2122 of the drain three-way valve 216 communicates with the sewage recovery pipeline 242, negative pressure can be formed at the water outlet 2121 of the sewage tee branch 212 through the fan 215, so that the fan 215 simultaneously sucks the sewage in the sewage recovery pipeline 242 and the sewage container 210 into the first sewage tank 21.

[0115]In the example of the disclosure, the single fan 215 can be used for draining of the sewage container 210, the sewage recovery pipeline 242 and the dust collecting box 230 of the cleaning device 200. By switching the air flow channel, the fan 215 can be used for three different functions of the base station 100, which can reduce setting of driving components on the base station 100, effectively simplify the structure of the base station 100, and help to reduce the volume of the base station 100 and improve a space utilization rate of the base station 100.

[0116]Referring to FIG. 4 and FIG. 5 in combination, in some examples, the wet cleaner 20 includes the above-mentioned housing 29, and the sewage interface 272 can be disposed on the housing 29. In this example, by switching the connection state of the fan 215, the fan 215 can be used as a negative pressure source during the use of the washer 24; the fan 215 can also be used as a negative pressure source when the base station 100 cleans the sewage container 210 of the cleaning device 200. When the sewage container 210 of the cleaning device 200 or the washing tank 101 of the base 10 are cleaned, the base 10 can only be configured to dock the cleaning device 200, or the base 10 can only be used for providing the first sewage pipeline 12, which can shorten residence time of the sewage on the base 10 and reduce a storage amount and residence time of pollutants on the base 10, thereby reducing possibility of bacteria breeding on the base 10 and improving the cleanliness of the base 10. On the other hand, a space for sewage to flow is formed through the first sewage pipeline 12, which can facilitate connection between the cleaning device 200 and the sewage transfer port 122 when the cleaning device 200 is docked on the base 10, thus reducing operation steps of connecting the cleaning device 200 and the drain three-way valve 216 through an external pipe, simplifying the user's operation, and improving automation performance of the process in which the base station 100 is docked with the cleaning device 200.

[0117]Referring to FIGS. 12 and 31, in some examples, the water tank assembly 1001 includes a first clean water tank 22, the power assembly 1003 includes the water pump 23, the first pipeline assembly 1002 includes a first clean water pipeline 13, and the second pipeline assembly 215 includes a second clean water pipeline 204.

In the second mode, the water pump 23 is configured to pump the clean water in the first clean water tank 22 to the surface. The second clean water pipeline 204 can be used as a pipeline on the wet cleaner 20 for docking with the base 10, the first clean water pipeline 13 can be used as a pipeline on the base 10 for docking the wet cleaner 20, and the water pump 23 in this example can be used as a power source to pump the water in the first clean water tank 22 to the surface in the second mode, so that the wet cleaner 20 can be used for wet cleaning of the surface. The water pump 23 can also be configured to transport the water source of the first clean water tank 22 of the wet cleaner 20 to the base 10 via the second clean water pipeline 204 and the first clean water pipeline 13 in turn in the first mode. In this example, the wet cleaner 20 can be configured to supply water to the base 10, which can include supplying water to components on the base 10 or supplying water to the cleaning device 200 docked on the base 10.

[0118]In some examples, the base 10 is provided with the washing tank 101, and the first clean water pipeline 13 communicates with the washing tank 101; in this example, the first clean water pipeline 13 can be used as a pipeline for the washing tank 101 to communicate with the wet cleaner 20, and the clean water in the first clean water tank 22 can be pumped by the water pump 23 to the washing tank 101 through the second clean water pipeline 204 and the first clean water pipeline 13 in turn. In the first mode, the wet cleaner 20 is installed on the base 10, and the first clean water pipeline 13 and the second clean water pipeline 204 can be used as a waterway passage between the first clean water tank 22 and the washing tank 101, so that the wet cleaner 20 can be configured to add water into the washing tank 101. The wet cleaner 20 in this example can add water into the washing tank 101 at any time, or the wet cleaner 20 can be configured to add water into the washing tank 101 only when the cleaning device 200 is docked on the base 10. In this example, the clean water added into the washing tank 101 can be configured to clean the cleaning components of the cleaning device 200.

[0119]In some examples, the first clean water pipeline 13 is configured to communicate with the clean water container 220 of the cleaning device 200 when the cleaning device 200 is docked on the base 10. In this example, the first clean water pipeline 13 can be used as a pipeline for the cleaning device 200 to communicate with the wet cleaner 20, and the clean water in the first clean water tank 22 can be pumped by the water pump 23 to the cleaning device 200 through the second clean water pipeline 204 and the first clean water pipeline 13 in turn, so as to add water into the cleaning device 200 through the wet cleaner 20. In the first mode, the wet cleaner 20 is docked on the base 10, and the power assembly 1003 can be used as a power source to pump out clean water in the first clean water tank 22, in which the base 10 can only be configured to provide a water supply flow channel for the cleaning device 200 and the wet cleaner 20. For example, the base 10 may be provided with a water supply transfer port 132 and the sewage receiving port 121 for docking with the cleaning device 200. When the cleaning device 200 is docked at a preset position on the base 10, the water supply transfer port 132 and the sewage receiving port 121 are respectively connected with the corresponding ports of the cleaning device 200.

[0120]Referring to FIG. 15, in some examples, the base 10 may include a power supply module 15 which may be connected to the commercial power. For example, the cleaning device 200 has the first power module 240. After the cleaning device 200 is docked on the base 10, the power supply module 15 can be electrically connected with the first power module 240, so that the power supply module 15 can be used for charging the cleaning device 200. The power supply module 15 may include a power cord for accessing the power supply, and the power supply module 15 may also include a battery module with charging and discharging functions. The power supply module 15 can charge the cleaning device 200 by wired charging or wireless charging. The base 10 can be configured to supply power to the cleaning device 200; the cleaning device 200 has the first power module 240, which is electrically connected to the power supply module 15 when the water supply transfer port 132 and the sewage receiving port 121 are respectively connected to the corresponding ports of the cleaning device 200. For example, when the water supply transfer port 132 and the sewage receiving port 121 are respectively connected to the corresponding ports of the cleaning device 200, the dust collecting box 230 of the cleaning device 200 is connected with the air inlet port 141 of the dust collecting part 14. In some examples, the base 10 has the docking part 11, and the water supply transfer port 132, the sewage receiving port 121 and the air inlet port 141 can all be disposed at the docking part 11, which can facilitate docking of the cleaning device 200 with the above ports on one hand and can facilitate concentrated arrangement of the ports of the cleaning device on the other hand. For example, the docking part 11 may be a recess toward the inside of the base 10, and the water supply transfer port 132, the sewage receiving port 121 and the air inlet port 141 may be accommodated inside the docking part 11, so that the port components can be hidden on the base 10.

[0121]In some examples, the base 10 is provided with the washing tank 101, and the first clean water pipeline 13 includes a second main pipeline 133, a third sub-pipeline 134 and a fourth sub-pipeline 135 which communicate with the second main pipeline 133, the second main pipeline 133 communicates with the second clean water pipeline 204, the third sub-pipeline 134 communicates with the washing tank 101, and the fourth sub-pipeline 135 is configured to communicate with the clean water container 220 of the cleaning device 200 when the cleaning device 200 is docked with the base 10. In this example, the first clean water pipeline 13 is provided with two branches of the third sub-pipeline 134 and the fourth sub-pipeline 135, which can be configured to add water to the washing tank 101 and the cleaning device 200 respectively, so as to facilitate separate docking, separate management and waterway switching of the two waterways. In the first mode, the water pump 23 pumps water out of the first clean water tank 22, the clean water can enter the washing tank 101 along the second clean water pipeline 204, the second main pipeline 133 and the third sub-pipeline 134 in turn, and can also enter the clean water container 220 of the cleaning device 200 along the second clean water pipeline 204, the second main pipeline 133 and the fourth sub-pipeline 135 in turn.

[0122]Referring to FIGS. 12 and 13, in some examples, the base 10 is provided with the second clean water tank 40, and the second clean water tank 40 is provided with a third clean water pipeline 41. In the first mode, the third clean water pipeline 41 communicates with the second clean water pipeline 204. In this example, the second clean water tank 40 can be used as a mechanism for storing water on the base 10. In the first mode, when the wet cleaner 20 is installed on the base 10, the clean water in the first clean water tank 22 can be conveyed by a negative pressure device to the second clean water tank 40 via the second clean water pipeline 204 and the third clean water pipeline 41, so as to add water to the base 10 through the wet cleaner 20. For example, the negative pressure device can be the water pump 23. In the first mode, the water pump 23 is configured to provide power to pump the water in the first clean water tank 22 to the second clean water tank 40 through the second clean water pipeline 204 and the third clean water pipeline 41 in turn.

The second clean water tank 40 in this example can be configured to add water to the cleaning device 200. When the cleaning device 200 is docked on the base 10, the water pump 23 of the second clean water tank 40 can be sent to the clean water container 220 of the cleaning device 200 through a negative pressure device which can be disposed on the base 10 or the cleaning device 200. For example, in the first mode, the water pump 23 is configured to provide power to pump the water in the first clean water tank 22 to the second clean water tank 40 through the second clean water pipeline 204 and the third clean water pipeline 41 in turn. When the cleaning device 200 is docked on the base 10, the third clean water pipeline 41 can be connected to the clean water container 220 of the cleaning device 200, so that the second clean water tank 40 can be configured to temporarily store the clean water output by the wet cleaner 20. When it is necessary to add water to the cleaning device 200, the water in the second clear water tank 40 is added to the cleaning device 200.

[0124]In some examples, the third clean water pipeline 41 is configured to connect with the washing tank 101, and the second clean water tank 40 adds water to the washing tank 101 through the third clean water pipeline 41. In this example, the third clean water pipeline 41 can be used as a water flow channel between the second clean water tank 40 and the washing tank 101, and the water in the second clean water tank 40 can be added into the washing tank 101 through the third clean water pipeline 41. For example, a negative pressure device can be provided on the base 10 to pressurize the water in the second clean water tank 40, so that the water can enter the washing tank 101 along the third clean water pipeline 41; for example, a water level of the second clean water tank 40 may be higher than that of the washing tank 101, so that water can flow into the washing tank 101 under the action of gravity.

[0125]Referring to FIG. 14, in some examples, the base 10 is provided with the second clean water tank 40 and the washing tank 101, and the second clean water tank 40 is provided with the third clean water pipeline 41. The third clean water pipeline 41 includes a fourth main pipeline 411, a seventh sub-pipeline 412 and an eighth sub-pipeline 413 which communicate with the fourth main pipeline 411, and the fourth main pipeline 411 is connected with the second clean water tank 40. The seventh sub-pipeline 412 is configured to connect the clean water container 220 of the cleaning device 200 when the cleaning device 200 is docked on the base 10. The second clean water tank 40 adds water to the clean water container 220 of the cleaning device 200 through the fourth main pipeline 411 and the seventh sub-pipeline 412 in turn, and the eighth sub-pipeline 413 is configured to connect with the washing tank 101, and the second clean water tank 40 adds water to the washing tank 101 through the fourth main pipeline 411 and the eighth sub-pipeline 413 in turn. In this example, the third clean water pipeline 41 is provided with two branches, one of which is the fourth main pipeline 411 and a seventh sub-pipeline 412 and is configured to connect the second clean water tank 40 with the clean water container 220 of the cleaning device 200, the other of which is the fourth main pipeline 411 and an eighth sub-pipeline 413 and is configured to connect the second clean water tank 40 with the washing tank 101. In this example, any one of the two branches can be opened, or both of the branches can be opened at the same time. In this example, a negative pressure device can be disposed on the base 10 to output the water in the second clean water tank 40 into the two branches through negative pressure, and for example, the negative pressure device can be disposed on the fourth main pipeline 411.

[0126]In some examples, the wet cleaner 20 further includes the liquid storage tank 257 configured to store cleaning liquid and a cleaning liquid power device 258 connected to the liquid storage tank 257 and configured to pump out the cleaning liquid in the liquid storage tank 257 so that the cleaning liquid can be mixed with water. The cleaning liquid power device 258 is configured to provide negative pressure, so that the cleaning liquid can be output from the liquid storage tank 257 to a preset position. In this example, the cleaning liquid can be pumped out and output to the second clean water pipeline 204, or directly pumped out to the water supply pipe 243. For example, the cleaning liquid in the liquid storage tank 257 can be pressurized by the cleaning liquid power device 258, so that the cleaning liquid can be pumped to the inlet of the water pump 23, and then the water pump 23 can be configured to output cleaning liquid and clean water at the same time.

[0127]Referring to FIG. 32, in some examples, the wet cleaner 20 further includes a third one-way valve 259 which is connected between the cleaning liquid power device 258 and the water pump 23, and an inlet of the third one-way valve 259 is connected to the cleaning liquid power device 258 and an outlet thereof is connected to the water pump 23.

[0128]The third one-way valve 259 is configured to control the flow direction of the liquid between the liquid storage tank 257 and the water pump 23, so as to reduce the possibility of reverse flow of the liquid. In this example, the third one-way valve 259 is connected between the cleaning liquid power device 258 and the water pump 23, which can control the flow direction of the cleaning liquid on one hand, and reduce the possibility that the clean water output from the first clean water tank 22 impacts the cleaning liquid power device 258 on the other hand. It can be understood that the third one-way valve 259 can also be located between the cleaning power device 258 and the liquid storage tank 257, the inlet of the third one-way valve 259 can be connected with the liquid storage tank 257, and the outlet of the third one-way valve 259 can be connected with the cleaning power device 258. The third one-way valve 259 in the example of the disclosure can be a solenoid valve or a mechanical valve.

[0129]In some examples, the wet cleaner 20 includes the washer 24 connected to the first clean water tank 22 through the water supply pipe 243 which can be connected to the brush head 241 and configured to output water to the surface, and one end of the water supply pipe 243 close to the brush head 241 can be provided with a nozzle to spray water to the surface. In this example, the water supply pipe 243 can be partially integrated on the brush head 241 to facilitate fixing of the water supply pipe 243. A direction in which the water supply pipe 243 sprays water can be set as required. For example, when the brush head 241 is relatively moved, the water supply pipe 243 can also move synchronously, so that the brush head 241 can clean the surface and soaked by the water.

[0130]In some examples, the inlet of the water pump 23 is connected with the first clean water tank 22, the outlet of the water pump 23 is connected with the water supply pipe 243, and the water pump 23 is configured to convey the water in the first clean water tank 22 to the outside of the brush head 241.

One end of the water supply pipe 243 away from the brush head 241 is connected to the water pump 23. When the water pump 23 is running, the water pump 23 can pump water out of the first clean water tank 22, and the water can be output to the outside of the brush head 241 along the water supply pipe 243. In this example, the water in the first clean water tank 22 is output by the water pump 23, the water can be delivered to the surface in time when the nozzle is used, so that the brush head 241 can perform wet cleaning on the surface, which facilitates improving cleaning efficiency. In some examples, the wet cleaner 20 includes the second power module 26, which is electrically connected with the water pump 23, so that the second power module 26 can be configured to supply power to the water pump 23. In some examples, the wet cleaner 20 includes a main control board 28, and the main control board 28 is electrically connected with the water pump 23 to control operation of the water pump 23 through the main control board 28.

For example, the wet cleaner 20 further includes a water supply control valve 25, an inlet of which is connected with the outlet of the water pump 23, and an outlet of which is connected with the water supply pipe 243 and is configured to connect the water supply receiving port 131 when the wet cleaner 20 is installed on the base 10.

[0133]The water supply control valve 25 can serve as an intermediate connector between the water pump 23 and an external interface, and can form a water flow channel for water to flow. The inlet of the water supply control valve 25 is connected with the water pump 23, and the clean water output by the water pump 23 enters the water supply control valve 25. The outlet of the water supply control valve 25 may be connected with the water supply pipe 243 for outputting water to the surface. The outlet of the water supply control valve 25 can also be configured to be connected to the water supply receiving port 131 when the wet cleaner 20 is installed on the base 10. For example, the water supply control valve 25 may have one inlet and two outlets, in which one outlet may be configured to connect the water supply pipe 243 and the other outlet may be configured to be connected to the water supply receiving port 131 when the wet cleaner 20 is installed on the base 10. In some examples, the wet cleaner 20 is provided with a water supply interface 273 configured to be connected to the water supply receiving port 131. For example, the water supply interface 273 may be provided on the housing 29.

[0134]In some examples, the water supply control valve 25 includes a water supply valve body 251 and a water supply valve spool 252; the water supply valve body 251 is provided with a water supply flow channel, and a clean water inlet 2511, a first clean water outlet 2512 and a second clean water outlet 2513 which separately communicate with the water supply flow channel. The clean water inlet 2511 communicates with the outlet of the water pump 23, the first clean water outlet 2512 is connected with the water supply pipe 243, and the second clean water outlet 2513 is configured to connect the water supply receiving port 131 when the wet cleaner 20 is installed on the base 10.

[0135]The water supply valve body 251 may be configured to form a water supply flow channel for liquid to flow.

The clean water inlet 2511 is connected with the outlet of the water pump 23, so that the water output by the water pump 23 can enter the water supply flow channel. The first clean water outlet 2512 is configured to connect the water supply pipe 243. When the water in the water supply flow channel is output through the first clean water outlet 2512, the first clean water tank 22 can be configured to supply water to the surface. The second clean water outlet 2513 is configured to be connected to the water supply receiving port 131 when the wet cleaner 20 is installed on the base 10, so that the first clean water tank 22 can be configured to add water to the clean water container 220 of the cleaning device 200 docked on the base 10. The water supply flow channel described in the example of the disclosure can be used for conveying clean water or mixed liquid of clean water and cleaning liquid. In some examples, the base 10 includes a washing tank 101, and the first clean water tank 22 can be configured to supply water to the washing tank 101.

[0136]The water supply valve spool 252 is movably connected to the water supply valve body 251 and is at least partially movably disposed in the water supply flow channel. The water supply valve spool 252 is configured to communicate the clean water inlet 2511 and the first clean water outlet 2512, or configured to communicate the clean water inlet 2511 and the second clean water outlet 2513 when the first clean water tank 22 is installed on the base 10.

[0137]In this example, the drain valve spool 2163 can move relative to the water supply valve body 251, which means that the drain valve spool 2163 can rotate, slide or rotate and slide together relative to the water supply valve body 251. When the water supply valve spool 252 moves relative to the water supply valve body 251, the water supply valve spool 252 is configured to control switching of the water flow channel in the water supply flow channel. When the wet cleaner 20 is used alone and needs to spray water on the surface, the water supply valve spool 252 can control the clean water inlet 2511 to communicate with the first clean water outlet 2512, so that the water in the first clean water tank 22 can be delivered to the water supply pipe 243. When the cleaning device 200 is docked on the base 10 and needs to add water to the clean water container 220 of the cleaning device 200, the water supply valve spool 252 can be configured to control the clean water inlet 2511 to communicate with the second clean water outlet 2513, so that the water in the first clean water tank 22 can enter the water supply receiving port 131 through the water pump 23, the clean water inlet 2511 and the second clean water outlet 2513 in turn. For example, the water supply valve can be driven to move relative to the water supply valve body 251 by electric driving or by mechanical driving.

[0138]Referring to FIG. 32, in some examples, the wet cleaner 20 further includes a switch 253 connected to the water supply pipe 243 to control the opening degree of the water supply pipe 243. The opening degree of the water supply pipe 243 includes opening or closing time of the water supply pipe 243 and a flow of the water supply pipe 243. The switch 253 in this example may be a valve body with a flow control function. In this example, by controlling the opening degree of the water supply pipe 243 by the switch 253, when the wet cleaner 20 is used alone, the time and water amount the water supply pipe 243 outputs water can be controlled by the switch 253 for cleaning in different scenes.

[0139]Referring to FIG. 32 again, in some examples, the wet cleaner 20 further includes a booster pump 254 connected to the water supply pipe 243 and configured to boost and output water in the water supply pipe 243. The booster pump 254 is configured to boost the water entering the water supply pipe 243 to increase the pressure of the water output from the water supply pipe 243. The booster pump 254 can be connected to the middle of the water supply pipe 243 or an end of the water supply pipe 243 close to the water supply control valve 25.

[0140]Referring to FIG. 32 again, in some examples, the wet cleaner 20 further includes a first one-way valve 255 connected to the water supply pipe 243 and connected to the inlet or outlet of the booster pump 254.

[0141]The first one-way valve 255 is configured to control the one-way flow of water from the water supply control valve 25 to the water supply pipe 243, so as to reduce the possibility of reverse flow of water in the water supply pipe 243.

For example, the first one-way valve 255 may be disposed at the outlet of the booster pump 254, and the inlet of the first one-way valve 255 may be connected with the outlet of the booster pump 254.

[0142]Referring to FIG. 32 again, in some examples, the wet cleaner 20 further includes a second one-way valve 256 which is connected to the water supply control valve 25 and located at the second clean water outlet 2513. The second one-way valve 256 is configured to control clean water to flow from the second clean water outlet 2513 to the water supply receiving port 131 when the wet cleaner 20 is installed on the base 10.

[0143]The second one-way valve 256 is configured to control the one-way flow of water output from the second clean water outlet 2513. In this example, the inlet of the second one-way valve 256 can be connected to the second clean water outlet 2513 of the water supply control valve 25. When the wet cleaner 20 is installed on the base 10, the second one-way valve 256 can cause the water output from the second clean water outlet 2513 to flow in one way to the water supply receiving port 131, thereby reducing the possibility of reverse flow of the clean water to the second clean water outlet 2513.

[0144]In some examples, the base 10 further has the water supply transfer port 132 connected to the first clean water pipeline 13. The base 10 has the washing tank 101 connected with the water supply transfer port 132. In this example, water in the second clean water tank 40 can be added into the washing tank 101 to clean the cleaning device 20.

[0145]In some examples, the base 10 further has the water supply transfer port 132 connected to the first clean water pipeline 13. The cleaning device 200 has the clean water container 220, and the water supply transfer port 132 is configured to connect the clean water container 220 when the cleaning device 200 is docked on the base 10. In this example, the water in the second clean water tank 40 can be added into the clean water container 220 of the cleaning device 200.

[0146]In some examples, the wet cleaner 20 is a cloth washer 24, the wet cleaner 20 further includes the washer 24 connected with the water tank assembly 1001, the water tank assembly 1001 and the power assembly 1003 are disposed side by side, and the washer 24 is disposed at the side of the power assembly 1003. In the first mode, the washer 24 is close to the dust collecting part 14. The water tank assembly 1001 in this example can be disposed on the housing 29 side by side with the power assembly 1003 to make full use of the space of the housing 29. For example, the power assembly 1003 may be disposed in a gap between the first clean water tank 22 and the first sewage tank 21, so that the power assembly 1003 can connect the first clean water tank 22 and the first sewage tank 21 nearby. The washer 24 is disposed on a side of the power assembly 1003, which means that the washer 24 can be installed on a part of the housing 29 close to the power assembly 1003, so as to shorten the connection pipeline between the washer 24 and the power assembly 1003. In the first mode, the washer 24 is close to the dust collecting part 14 which can support and limit the washer 24 to improve stability of the wet cleaner 20 on the base 10. For example, in the first mode, the washer 24 can be placed above the dust collecting part 14, so that the dust collecting part 14 can lift the washer 24, reducing the possibility that the wet cleaner 20 is tilted or dislocated on the base 10.

[0147]Referring to FIGS. 5 and 11, in some examples, the wet cleaner 20 has a second wall 27, the wet cleaner 20 has the housing 29, and the second wall 27 is a side wall of the housing 29. When the wet cleaner 20 is installed on the base 10, the second wall 27 of the wet cleaner 20 may be disposed opposite to the first wall 19 of the base 10, and for example, the second wall 27 may adhere to the first wall 19. For example, the second wall 27 may be provided with functional components configured to be connected to the sewage transfer port 122, the water supply receiving port 131 and the air duct port 192, so that the corresponding ports can be connected to each other when the wet cleaner 20 is installed on the base 10.

[0148]In some examples, the power supply module 15 includes a first connecting terminal 151 which may be disposed on the first wall 19; the wet cleaner 20 has the second power module 26 which can be configured to connect an external power supply device so as to supply power to internal components of the wet cleaner 20. The second power module 26 may include a second connecting terminal 261 configured to be connected to the first connecting terminal 151, and the second connecting terminal 261 may be disposed on the second wall 27. When the wet cleaner 20 is installed on the base 10 and the cleaning device 200 is docked at a preset position on the base 10, the power supply module 15 can be configured to charge at least one of the second power module 26 and the cleaning device 200. The power supply may include that the power supply module 15 continuously provides power for the second power module 26 and that the power supply module 15 charges the second power module 26; meanwhile, the wet cleaner 20 may be connected to the sewage transfer port 122, the water supply receiving port 131 and the air duct port 192 on the base 10, so as to clean the cleaning device 200.

[0149]In some examples, the wet cleaner 20 has a main control board 28 which is electrically connected with the second power module 26. In some examples, the power supply module 15 includes the first connecting terminal 151, the second power module 26 includes the second connecting terminal 261. When the wet cleaner 20 is installed on the base 10, the first connecting terminal 151 is electrically connected with the second connecting terminal 261. The first connecting terminal 151 and the second connecting terminal 261 in this example may be PIN pins or other structures that can be used for electric signal transmission. For example, both the first connecting terminal 151 and the second connecting terminal 261 may be in multiple groups, and the multiple groups of first connecting terminals 151 and second connecting terminals 261 may be disposed in one-to-one correspondence. In some examples, the first connecting terminal 151 and the second connecting terminal 261 may be two groups of quick plug connectors. In some examples, the first connecting terminal 151 and the second connecting terminal 261 may be in point contact, surface contact or line contact, and the connecting state of the first connecting terminal 151 and the second connecting terminal 261 may be changed by changing the position and contact area of the contact surface between the first connecting terminal 151 and the second connecting terminal 261.

[0150]Referring to FIGS. 5 and 11 together, in some examples, the base 10 further includes a first connecting part 193, and the wet cleaner 20 further includes a second connecting part 262. The first connecting part 193 is detachably connected with the second connecting part 262. The first connecting part 193 is disposed on the base 10, and the second connecting part 262 is disposed on the wet cleaner 20. The first connecting part 193 and the second connecting part 262 can be used as connecting parts between the base 10 and the wet cleaner 20. When the wet cleaner 20 is installed on the base 10, the base 10 can be aligned with the second connecting part 262 of the wet cleaner 20 through the first connecting part 193, the first connecting part 193 and the second connecting part 262 can serve as a fool-proofing alignment structure between the base 10 and the wet cleaner 20, and an intermediate connector for mutual connection between the base 10 and the wet cleaner 20. For example, the first connecting part 193 can form connection with the second connecting part 262 to align the first connecting part 193 with the second connecting part 262 when the wet cleaner 20 is installed. For example, the first connecting part 193 and the second connecting part 262 form a mutual limit, and movement of the wet cleaner 20 relative to the base 10 can be limited by the mutual fitting of the first connecting part 193 and the second connecting part 262, which includes detaching the wet cleaner 20 from the base 10 or translating the wet cleaner 20 relative to the base 10. In some examples, when the first connecting part 193 and the second connecting part 262 are connected with each other, the base 10 can be electrically connected with the wet cleaner 20, so as to reduce the mutual dislocation of the two parts, and reduce an open circuit caused by inaccurate connecting. In some examples, the first connecting part 193 and the second connecting part 262 are connected by at least one of insertion, locking, magnetic attraction, pin connection and bolt connection.

[0151]In some examples, the wet cleaner 20 is detachably installed on the base 10, and the first connecting part 193 is detachably connected with the second connecting part 262. When the wet cleaner 20 is installed on the base 10, the first connecting part 193 and the second connecting part 262 can be connected with each other, so that the wet cleaner 20 can maintain a preset position and a preset state on the base 10, which means that the wet cleaner 20 can remain in a connected state at the preset position on the base 10; the preset state includes at least one of a preset angle, posture and connection mode that the wet cleaner 20 maintains on the base 10. The first connecting part 193 and the second connecting part 262 in this example can also be used for mutual alignment between the wet cleaner 20 and the base 10, so that the wet cleaner 20 can be quickly docked with the base 10.

[0152]In this example, the shape of the first connecting part 193 can be consistent with the shape of the corresponding second connecting part 262. When the wet cleaner 20 is installed on the base 10, the wet cleaner 20 can be positioned through the fitting of the first connecting part 193 and the second connecting part 262, thus facilitating the mutual alignment between the wet cleaner 20 and the base 10. When the wet cleaner 20 is installed on the base 10, the first connecting part 193 and the second connecting part 262 can be configured to restrict the wet cleaner 20 from moving in a specific direction relative to the base 10. Taking the first connecting part 193 and the second connecting part 262 disposed up and down as an example, after the first connecting part 193 is inserted into the second connecting part 262, displacement of the wet cleaner 20 relative to the base 10 in the horizontal direction can be prevented, thereby improving stability of the wet cleaner 20.

[0153]In some examples, there may be a plurality of first connecting parts 193 and a plurality of second connecting parts 262, and the first connecting parts 193 may have a one-to-one or one-to-many correspondence with the second connecting parts 262. In some examples, general contours of the first connecting part 193 and the second connecting part 262 can be triangular, quadrilateral, pentagonal, hexagonal, oval, or the like, so that when the wet cleaner 20 is installed on the base 10, the wet cleaner 20 can no longer rotate relative to the base 10, thereby keeping the wet cleaner 20 in a preset state.

[0154]For example, the first connecting part 193 may be provided integrally with the wet cleaner 20. For example, the first connecting part 193 and the wet cleaner 20 may be separately provided and connected and fixed to each other.

[0155]For example, the second connecting part 262 may be provided integrally with the base 10. For example, the second connecting part 262 may be disposed separately from the base 10 and connected and fixed to each other.

[0156]In some examples, the first connecting part 193 and the second connecting part 262 are connected by at least one of insertion, locking, magnetic attraction, pin connection and bolt connection.

[0157]The insertion means that the first connecting part 193 and the second connecting part 262 are at least partially inserted into and fit each other, so that the first connecting part 193 and the second connecting part 262 can be mutually limited. For example, one of the first connecting part 193 and the second connecting part 262 can have a convex structure and the other can have a concave structure, and the first connecting part 193 can be inserted into the second connecting part 262. In some examples, the first connecting part 193 is provided protruding from the first wall 19 toward the outside direction of the base 10, the second connecting part 262 is recessed toward the inside of the housing 29 on the second wall 27, and the first connecting part 193 and the second connecting part 262 are inserted into each other.

[0158]The locking means that the first connecting part 193 and the second connecting part 262 can lock with each other, so that the first connecting part 193 and the second connecting part 262 can form mutual limit, and one of the first connecting part 193 and the second connecting part 262 can be deformable or movable, so that the first connecting part 193 and the second connecting part 262 can lock with each other. In this example, the first connecting part 193 can rotate, slide, or rotate and slide relative to the second connecting part 262, so that the first connecting part 193 and the second connecting part 262 can limit each other.

[0159]The magnetic connection means that one of the first connecting part 193 and the second connecting part 262 is made of magnetic material, and the other is at least made of magnetically attractive material, so that the first connecting part 193 and the second connecting part 262 can absorb each other. The magnetically attractive material can be made of materials such as magnets, ferromagnetic materials that can be attracted by magnets, or materials combined by ferromagnetic materials that can be attracted by magnets with other materials.

[0160]The bolt connection means that one of the first connecting part 193 and the second connecting part 262 may include a bolt, and the other may include a hole structure fitting the bolt.

[0161]The pin connection means that one of the first connecting part 193 and the second connecting part 262 can be a pin, and the other can be a pin hole fitting the pin.

[0162]In some examples, the first connecting part 193 and the second connecting part 262 may be connected in two or more connection modes. For example, the first connecting part 193 and the second connecting part 262 can be inserted into each other, and at the same time, the first connecting part 193 and the second connecting part 262 can be magnetically attracted to each other, so as to improve connection reliability of the first connecting part 193 and the second connecting part 262 and facilitate mutual alignment between the first connecting part 193 and the second connecting part 262.

[0163]In some examples, the first connecting part 193 is disposed on the first wall 19 and the second connecting part 262 is disposed on the second wall 27. When the wet cleaner 20 is installed on the base 10, the second wall 27 is disposed opposite to the first wall 19, and the first connecting part 193 may be connected to the second connecting part 262. In this example, when the first wall 19 and the second wall 27 are connected to each other, the first connecting part 193 and the second connecting part 262 can be hidden at the first wall 19 and the second wall 27, so that the first connecting part 193 and the second connecting part 262 can form a hidden connecting structure, which on one hand can fully utilize the space between the first wall 19 and the second wall 27, and on the other hand can reduce space occupation outside the wet cleaner 20 and the base 10, facilitating improving aesthetics of the base station. Moreover, when it is necessary to form an electrical connection between the base 10 and the wet cleaner 20, electrically connecting parts between the base 10 and the wet cleaner 20 are hidden at the first connecting part 193 and the second connecting part 262, so as to reduce exposure of the electrically connecting parts and facilitate waterproof design of the electrically connecting parts between the base 10 and the wet cleaner 20.

[0164]In some examples, the wet cleaner 20 includes the housing 29, and the sewage interface 272 communicating with the first sewage tank 21 is provided on the housing 29. The sewage interface 272 can be configured to be connected to the sewage transfer port 122 of the base 10. For example, the housing 29 is provided with the water supply interface 273 connecting the first clean water tank 22, and the water supply interface 273 can be configured to be connected to the water supply receiving port 131 of the base 10. For example, the housing 29 is provided with an air duct interface 274 connecting the sewage power device (that is, the fan 215 in the drawings), and the air duct interface 274 can be configured to be connected to the air duct port 192 of the base 10. In the example of the disclosure, after the first connecting part 193 and the second connecting part 262 fit each other, relative positions of the wet cleaner 20 and the base 10 are determined, so that the corresponding sewage interface 272, water supply interface 273 and air duct interface 274 can be in preset positions, so as to facilitate alignment and connection between the ports, and the user does not need to perform port connection furthermore, which can facilitate the user's operation. In some examples, when the wet cleaner 20 is installed on the base 10, the air duct port 192 can be connected with the wet cleaner 20, and negative pressure can be formed at the air outlet port 142 of the dust collecting bin 143 through the wet cleaner 20. For example, the dust collecting part 14 includes a hard box-like structure, and the dust collecting part 14 in this example of the disclosure may be an independent box connected to the base 10, or may be a cavity structure integrally formed with the base 10.

[0165]Referring to FIGS. 33 and 34, in some examples, a guide structure 50 may be disposed between the first connecting part 193 and the second connecting part 262, and the guide structure 50 may be configured to guide the wet cleaner 20, so that the first connecting part 193 and the second connecting part 262 can be connected to each other.

[0166]Referring to FIGS. 33 and 34, in some examples, the guide structure 50 may include a first guide part 191 and a second guide part 271. The first guide part 191 and the second guide part 271 can guide the wet cleaner 20 and fit each other, so that when the wet cleaner 20 is installed on the base 10, and the wet cleaner 20 is guided by the first guide part 191 and the second guide part 271, so that the wet cleaner 20 is installed on the base 10 according to a preset trajectory. In this example, the first guide part 191 and the second guide part 271 can be in sliding fit with each other, inside and outside fit with each other, or a combination thereof; the sliding fit means that the first guide part 191 and the second guide part 271 form a combination mode of a slide rail and a chute, so that the first guide part 191 and the second guide part 271 can slide relatively along a preset direction; the inside and outside fit means that one of the first guide part 191 and the second guide part 271 can be in a closed ring or an open ring, so that the first guide part 191 and the second guide part 271 can form an inside and outside fit structure.

[0167]Referring to FIGS. 35 to 45, in some examples, when the wet cleaner 20 is installed on the base 10, the second wall 27 is located above the first wall 19, and the guide structure 50 is configured to guide the wet cleaner 20 to be close to or away from the base 10 in the up-down direction. When being picked and placed, the wet cleaner 20 can be moved in the up-down direction, which on one hand can be more ergonomic for the user to pick when the user picks and places the wet cleaner 20; on the other hand, the space above the base 10 can be used to reduce the possibility of collision between the wet cleaner 20 and the wall, furniture and other structures outside the base 10 when the wet cleaner 20 is picked and placed; and on the other hand, when the user touches the base 10 or the wet cleaner 20 by mistake, the possibility that the wet cleaner 20 falls off the base 10 can be reduced. In some examples, an edge of the first wall 19 can be bent upward to form a protruding structure, and an edge of the second wall 27 can also be provided in a rounded corner or chamfer. When the first wall 19 and the second wall 27 fit each other, the chamfer on the second wall 27 can fit the inner surface of the protruding part of the edge of the first wall 19 to further restrict movement of the second wall 27 relative to the first wall 19 in the horizontal direction.

[0168]The second wall 27 is a wall surface of the bottom of the wet cleaner 20. When the wet cleaner 20 is installed on the base 10, the second wall 27 can be connected to the first wall 19, and the power module 26 can be hidden in a contact part between the wet cleaner 20 and the base 10, so as to improve safety of the wet cleaner 20 during charging.

[0169]In some examples, the first connecting part 193 at least partially protrudes toward the outside of the first wall 19. The first connecting part 193 forms a protruding structure on the outside of the first wall 19, so that the second connecting part 262 can be aligned with the first connecting part 193. The first connecting part 193 can form a blocking and protecting structure on the periphery of the power supply module 15 to protect the power supply module 15. When a foreign matter approaches the first wall 19, the first connecting part 193 can block the foreign matter and further protect the power supply module 15. For example, the first connecting part 193 may form an annular surrounding structure on the periphery of the power supply module 15 to form a shield on the periphery of the power supply module 15, and then form an annular blocking structure on the periphery of the power supply module 15, so as to reduce the possibility that water flows along the first wall 19 to the power supply module 15. In this example, the second connecting part 262 can be provided inward from the second wall 27 to the inside of the housing 29. When the wet cleaner 20 is installed on the base 10, the second connecting part 262 and the first connecting part 193 fit each other, and when the wet cleaner 20 is placed on the ground or other platforms, the second connecting part 262 does not interfere with the wet cleaner 20. For example, when the power supply module 15 is electrically connected with the power module 26, the first connecting part 193 can form a waterproof and protective structure on outer sides of the power supply module 15 and the power module 26 to reduce the possibility of leakage. For example, the first connecting part 193 may be a convex rib or a convex ring disposed beside the first connecting terminal 151.

[0170]In some examples, the first connecting part 193 has a bottom wall 1934 and a side wall 1935 disposed around the periphery of the bottom wall 1934, and an end of the side wall 1935 away from the bottom wall 1934 protrudes to the outside of the first wall 19; the first guide part 191 is connected to the side wall 1935, and when the wet cleaner 20 is installed on the base 10, the side wall 1935 is disposed around the periphery of the second connecting part 262. The side wall 1935 is disposed around the periphery of the bottom wall 1934, which means that the side wall 1935 is connected to the periphery of the bottom wall 1934. The end of the side wall 1935 away from the bottom wall 1934 protrudes toward the outside of the first wall 19, which means that the end of the side wall 1935 away from the bottom wall 1934 protrudes from the surface of the first wall 19, and the side wall 1935 encloses a concave area at the side of the bottom wall 1934.

[0171]In some examples, the side wall 1935 is disposed around the periphery of the second connecting part 262, so that the side wall 1935 and the second connecting part 262 form an inner-outer annular connection structure. For example, the side wall 1935 and the second connecting part 262 can be connected by at least one of insertion, locking, magnetic attraction, pin connection and bolt connection. In this example, the side wall 1935 is disposed around the periphery of the second connecting part 262, which can facilitate increasing the connection area between the side wall 1935 and the second connecting part 262, and can facilitate setting the connection mode between the side wall 1935 and the second connecting part 262 more flexibly.

[0172]In some examples, the base 10 includes the power supply module 15 connected to the bottom wall 1934 or the side wall 1935, the wet cleaner 20 includes the power module 26 configured to be electrically connected with the power supply module 15 when the first connecting part 193 is connected to the second connecting part 262.

[0173]For example, the power supply module 15 can be disposed adjacent to the first connecting part 193, and the power module 26 can be disposed adjacent to the second connecting part 262. In this example, when the first connecting part 193 and the second connecting part 262 are connected, the connection between the first connecting part 193 and the second connecting part 262 can be used as a positioning mechanism for the power supply module 15 and the power module 26. The power supply module 15 and the power module 26 which can be closer to the positioning mechanism can facilitate rapid positioning and connecting of the power supply module 15 and the power module 26 and reduce the possibility of mutual misalignment of the power supply module 15 and the power module 26. In this example, relative distances between the power supply module 15 and the first connecting part 193 as well as the power module 26 and the second connecting part 262 can be determined according to dimensions and shapes of the power supply module 15 and the power module 26. For example, the power supply module 15 and the power module 26 can be connected in wired connection, wireless connection or a combination thereof.

[0174]In some examples, the first connecting part 193 can be disposed around the periphery of the power supply module 15, and the first connecting part 193 can form an annular positioning or connecting structure around the periphery of the power supply module 15, which can increase the contact area between the first connecting part 193 and the second connecting part 262 on one hand, and improve connecting stability of the power supply module 15 on the other hand. For example, the first connecting part 193 may form a continuous annular structure around the outer periphery of the power supply module 15, or there may be a plurality of first connecting parts 193, and connecting lines of the first connecting parts 193 may enclose an annular structure around the periphery of the power supply module 15.

[0175]In some examples, the second connecting part 262 is disposed around the periphery of the power module 26 and can form an annular positioning mechanism on the periphery of the power module 26, which can increase the contact area between the second connecting part 262 and the first connecting part 193 on one hand, and improve connecting stability of the power module 26 on the other hand. For example, the second connecting part 262 may form a continuous annular structure around the outer periphery of the power module 26, or there may be a plurality of second connecting parts 262, and connecting lines of the second connecting parts 262 may enclose an annular structure around the periphery of the power module 26. The second connecting part 262 in this example can be configured to accommodate and support the power module 26, so that the power module 26 can be accommodated in the second connecting part 262. When the wet cleaner 20 is moved, the second wall 27 of the wet cleaner 20 can be used as its bottom wall to place the wet cleaner 20 on the ground, desktop or other surfaces, so as to reduce influence of the power module 26 on the wet cleaner 20 and help to improve stability of the wet cleaner 20.

[0176]In some examples, the power supply module 15 may be connected to the bottom wall 1934 or the side wall 1935. The bottom wall 1934 can be configured to support the power supply module 15, and the power supply module 15 can be connected to the bottom wall 1934 by welding or screws. The concave area can be configured to accommodate the first connecting terminal 151 of the power supply module 15.

[0177]The first guide part 191 is connected to the side wall 1935, so that the first guide part 191 and the second guide part 271 can fit each other. In some examples, the first guide part 191 may be a chute connected to the side wall 1935, and the second guide part 271 may be a slide rail connected to the second connecting part 262. In some examples, the first guide part 191 may be disposed around the periphery of the side wall 1935, and the first connecting part 193 may be protected by the first guide part 191, and at the same time, foreign matters may be prevented from contacting the first connecting terminal 151 by the first guide part 191. In this example, the side wall 1935 of the first connecting part 193 can enclose an annular area, so that the power supply module 15 can be partially hidden in the concave area formed by the first connecting part 193, thereby reducing the damage to the power supply module 15.

[0178]Referring to FIG. 38 again, in some examples, the bottom wall 1934 is provided with a first jack 1931, and the power supply module 15 includes an electric control board 152 and a first connecting terminal 151. The electric control board 152 can be disposed on a side of the bottom wall 1934 facing the inside of the base 10, and the first connecting terminal 151 penetrates the first jack 1931 and extends outward of the first wall 19. The first connecting terminal 151 is configured to be electrically connected with the power module 26 when the wet cleaner 20 is installed on the base 10.

[0179]In some examples, the side wall 1935 of the first connecting part 193 is disposed around the periphery of the first connecting terminal 151, and the side wall 1935 of the first connecting part 193 can be configured to form a protruding annular blocking structure on the periphery of the first connecting terminal 151, so that the side wall 1935 of the first connecting part 193 can protect the first connecting terminal 151.

[0180]For example, in some examples, the first guide part 191 at least partially protrudes to the outside of the first wall 19, and a distance between an end of the first guide part 191 away from the first wall 19 and the first wall 19 is a first distance D1, and a distance between an end of the first connecting terminal 151 away from the electric control board 152 and the first wall 19 is a second distance D2, and the first distance D1 is not less than the second distance D2. A height of the first guide part 191 protruding from the first wall 19 is higher than a height of the first connecting terminal 151 protruding from the first wall 19, so as to further protect the first connecting terminal 151. In this example, the first guide part 191 can be configured to block foreign matter outside the power supply module 15, so that when approaching the power supply module 15, the foreign matter is stopped by the first guide part 191 at first to reduce direct collision of foreign matter with the first connecting terminal 151, so as to reduce the possibility of deformation of the first connecting terminal 151.

[0181]The electric control board 152 can be connected to the bottom wall 1934, and the first connecting terminal 151 can extend to a direction away from the bottom wall 1934, so that the first connecting terminal 151 can protrude outside the electric control board 152. When the wet cleaner 20 is installed on the base 10, the second connecting terminal 261 can contact the first connecting terminal 151 to form an electrical connection. In some examples, the electric control board 152 is disposed on a side of the bottom wall 1934 facing away from the side wall 1935, and the first connecting terminal 151 passes through the first jack 1931 and protrudes from the side of the bottom wall 1934 facing away from the electric control board 152, and is blocked outside the electric control board 152 by the bottom wall 1934, so as to prevent dust or foreign matter from entering the electric control board 152. In some examples, one of the bottom wall 1934 and the electric control board 152 is provided with a positioning post 194, and the other is provided with a positioning hole 153. The positioning post 194 is embedded in the positioning hole 153, and the electric control board 152 and the bottom wall 1934 are positioned and fixed by the positioning post 194 and the positioning hole 153.

[0182]In some examples, the side wall 1935 has a first surface 1933, and the end of the first guide part 191 away from the first wall 19 is sealedly connected with the first surface 1933. The first surface 1933 is one of the surfaces of the side wall 1935. For example, the first surface 1933 may be the surface of the end of the side wall 1935 away from the bottom wall 1934. The sealing connection between the first surface 1933 and the first guide part 191 means that the joint between the first surface 1933 and the first guide part 191 forms seal. In this example, the sealing connection can be that the first surface 1933 and the first guide part 191 closely adhere to each other to form seal, or that the first surface 1933 and the first guide part 191 are sealed by an intermediate connector 294. In this example, the side wall 1935 and the first guide part 191 are in sealing connection, which can prevent foreign matter from entering the base 10 through a gap between the first guide part 191 and the side wall 1935.

[0183]In some examples, the first guide part 191 is provided with a first sealing part 1911, and the first surface 1933 is provided with a second sealing part 1932. The first sealing part 1911 is sealedly connected with the second sealing part 1932, and the first sealing part 1911 and the second sealing part 1932 are separately disposed around the bottom wall 1934. The first sealing part 1911 and the second sealing part 1932 fit each other to seal the gap between the first guide part 191 and the first surface 1933. In this example, the first sealing part 1911 and the second sealing part 1932 can closely adhere to each other to form seal. For example, at least one of the first sealing part 1911 and the second sealing part 1932 can be a sealing ring, which realizes sealing by elastic deformation of at least one of the first sealing part 1911 and the second sealing part 1932.

[0184]In some examples, the end of the first guide part 191 away from the first wall 19 is bent in the direction close to the first wall 19 to form the first sealing part 1911. The first sealing part 1911 can be provided integrally with the first guide part 191, and the first sealing part 1911 can be a flanging structure formed by inward bending of the end of the first guide part 191 away from the bottom wall 1934, so as to simplify the molding method of the first sealing part 1911. For example, the first guide part 191, the first sealing part 1911 and the first wall 19 may be provided integrally.

[0185]In some examples, the second sealing part 1932 is a groove opened on the first surface 1933, and the first sealing part 1911 is sealedly connected with an inner wall surface of the groove; the groove opened on the first surface 1933 means that a continuous or discontinuous sink groove is recessed on the first surface 1933, and the sink groove forms the second sealing part 1932.

[0186]In some examples, the second sealing part 1932 is a convex rib protruding from the first surface 1933, and the first sealing part 1911 is sealedly connected with the outer surface of the second sealing part 1932. In this example, the convex rib forming the second sealing part 1932 can closely adhere to the first sealing part 1911 to form mechanical seal. For example, there may be multiple convex ribs, and adjacent convex ribs fit inside and outside, and the first sealing part 1911 may be embedded in the groove formed between the adjacent convex ribs, so that the first sealing part 1911 and the second sealing part 1932 form seal.

[0187]Referring to FIGS. 43 to 47, in some examples, the base 10 includes the power supply module 15, and the wet cleaner 20 includes the power module 26. The power module 26 includes the main control board 28 and the second connecting terminal 261 electrically connected with the main control board 28. The main control board 28 is located inside the housing, the main control board 28 is located at the side of the second connecting part 262 facing the inside of the housing, and the second connecting part 262 is provided with a second jack 263. The end of the second connecting terminal 261 away from the main control board 28 is at least partially embedded in the second jack 263, and the second connecting terminal 261 is electrically connected to the power supply module 15 when the first connecting part 193 is connected to the second connecting part 262. In some examples, the wet cleaner 20 further includes an energy storage battery which is electrically connected with the main control board 28. The main control board 28 is disposed inside the housing 29, connected to the second connecting part 262, and disposed on the side of the second connecting part 262 facing the inside of the housing 29. The second connecting part 262 can be configured to support and fix the second connecting terminal 261, so as to keep the second connecting terminal 261 in a preset state in a preset position outside the main control board 28.

[0188]In some examples, the second connecting part 262 is provided with a second jack 263 which can be a through hole penetrating through the second connecting part 262, and the end of the second connecting terminal 261 away from the main control board 28 can be accommodated in the second jack 263, which can be configured to limit the second connecting terminal 261 on one hand to prevent the second connecting terminal 261 from being deformed too much to cause failure, and can protect the second connecting terminal 261 to prevent external foreign matter from damaging the second connecting terminal 261 on the other hand. On the other hand, when the second connecting terminal 261 is adapted to external power supply device, the second jack 263 can be configured to limit and initially position the external power supply device, so that the external power supply device can be aligned and adapted to the second connecting terminal 261 more easily. On the other hand, since the second jack 263 can limit a deformation range of the second connecting terminal 261, when an external power supply device and the second connecting terminal 261 are in contact with each other, the second connecting terminal 261 can always fit the external power supply device, thus reducing an open circuit between the second connecting terminal 261 and the external power supply device.

[0189]In some examples, the second wall 27 is partially recessed to the inside of the housing 27 to form the second guide part 271, the second connecting part 262 is connected to an end of the second guide part 271 extending into the housing 27. A distance between an end surface of the second connecting part 262 facing away from the main control board 28 and the main control board 28 is a third distance D3, a distance between an end surface of the second wall 27 facing away from the main control board 28 and the main control board 28 is a fourth distance D4, and the third distance D3 is not greater than the third distance D3. In this example, the second connecting part 262 may be accommodated inside the second guide part 271, and an end of the second connecting part 262 facing away from the main control board 28 does not protrude outside the second wall 27. When external foreign matter approaches the second guide part 271, the second wall 27 can block the foreign matter, so as to reduce the possibility that the foreign matter directly collides with the second connecting part 262.

[0190]The second connecting terminal 261 is connected to a side of the second connecting part 262 facing away from the second wall 27. In some examples, the first guide part 191 is disposed around the periphery of the second connecting part 262 and can block the periphery of the second connecting part 262 to form an annular sealing structure at the periphery of the second connecting part 262, and can be configured to prevent foreign matter from entering the inside of the housing 29 via the periphery of the second connecting part 262. In some examples, when the wet cleaner 20 is installed on the base 10, the end of the second connecting part 262 away from the main control board 28 can abut against the side wall 1935 or the bottom wall 1934 of the first connecting part 193, so that the second connecting part 262 can form seal with the side wall 1935 or the bottom wall 1934 of the first connecting part 193, and further play a sealing role in the joint between the first connecting terminal 151 and the second connecting terminal 261. In some examples, when the wet cleaner 20 is installed on the base 10, the inner wall surface of the second guide part 271 may abut against the outer wall surface of the first guide part 191 to form seal therebetween.

[0191]In some examples, the base 10 can be provided with the second sewage circuit 12, the sewage receiving port 121 and the sewage transfer port 122 as described in any of the above examples, the wet cleaner 20 is provided with the first sewage tank 21 and a sewage discharge power device (e.g. the fan 215), and the wet cleaner 20 is provided with the sewage interface 272 communicating with the first sewage tank 21. When the first connecting part 193 is connected to the second connecting part 262, the sewage interface 272 is connected to the sewage transfer port 122, and the sewage power device is connected to the first sewage tank 21. When the sewage interface 272 is connected to the sewage transfer port 122, the sewage power device is configured to form negative pressure on the second sewage circuit to suck the sewage in the second sewage circuit into the first sewage tank 21. In this example, the first connecting part 193 and the second connecting part 262 can be used as connecting parts between the sewage transfer port 122 and the sewage interface 272, so as to quickly align the sewage transfer port 122 with the sewage interface 272.

[0192]In some examples, the first guide part 191 is disposed around the periphery of the first connecting part 193, and both the first guide part 191 and the sewage transfer port are disposed on the first wall 19. In the height direction of the base 10, a distance between the upper end of the first guide part 191 and the bottom surface of the base 10 may be greater than a distance between the sewage transfer port 122 and the bottom surface of the base 10. The bottom surface of the base 10 refers to a lower surface of the base 10 for contacting the ground or other platforms when the base is placed on the ground or other platforms. In this example, by limiting the upper end of the first guide part 191 to be higher than the upper end of the sewage transfer port 122, the first guide part 191 can form a water-proof structure at the periphery of the first connecting part 193, so as to reduce the possibility that the sewage at the sewage transfer port 122 flows to the first connecting part 193 and the power supply module 15. For example, the sewage transfer port 122 in this example can be a through hole opened on the base 10 or a connecting port disposed on the base 10.

[0193]The first guide part 191 can be configured to form a ring-shaped protruding structure at the periphery of the first connecting part 193. When foreign matter approaches the first connecting part 193, the first guide part 191 can shield the foreign matter, so that the foreign matter cannot directly abut on the first connecting part 193.

[0194]Referring to FIG. 46, in some examples, the wet cleaner 20 has the housing 29, and the washer 24 includes the brush head 241 and the connecting pipe 245. The brush head 241 is configured to clean the surface. One end of the connecting pipe 245 is connected to the brush head 241, and the other end is connected to the housing 29. When the wet cleaner 20 is installed on the base 10, both the brush head 241 and the connecting pipe 245 are stored in the accommodating recess 171.

[0195]The brush head 241 may be a brush, a rubber brush or a combination of a brush and a rubber brush. The connecting pipe 245 is connected to the brush head 241. The connecting pipe 245 can be used to support and connect the brush head 241. The connecting pipe 245 can also be used to form a space for accommodating pipelines which can include cables with communication and/or power supply functions and can also include pipelines for forming the sewage recovery pipeline 242 and pipelines for forming the water supply pipe 243. For example, the connecting pipe 245 can be a round or oval hose, and can also be a corrugated pipe or a combination of hoses with various shapes. The connecting pipe 245 can be a combination of hoses and hard pipes, so as to improve the structural strength of the connecting pipe 245.

[0196]When the wet cleaner 20 is installed on the base 10, both the brush head 241 and the connecting pipe 245 are stored in the accommodating recess 171, so that both the brush head 241 and the connecting pipe 245 can be hidden in the accommodating recess 171, which on one hand can reduce exposure of the brush head 241 and the connecting pipe 245, and on the other hand can reduce interference of the brush head 241 and the connecting pipe 245 with external equipment.

[0197]In some examples, the wet cleaner 20 has a housing 29, and the housing 29 is provided with a protruding column 295 configured to wind a pipeline. When the wet cleaner 20 is installed on the base 10, the protruding column 295 is at least partially stored in the accommodating recess 171.

[0198]The pipeline may include cables with communication and/or power supply functions and can also include pipelines for forming the sewage recovery pipeline 242 and pipelines for forming the water supply pipe 243, and the pipeline may include the connecting pipe 245 described in the above examples.

[0199]The protruding column 295 is a protruding structure protruding outside the housing 29. The protruding column 295 can be configured to wind pipelines, which can reduce the problem of messy visual effect caused by pipeline scattering on one hand. On the other hand, when the wet cleaner 20 is installed on the base 10, the protruding column 295 is at least partially stored in the accommodating recess 171, which can facilitate the pipeline and the protruding column 295 to be stored in the accommodating recess 171 together. The protruding column 295 can be a cuboid, a cylinder or a special-shaped structure. For example, the protruding column 295 has a proximal end connected to the housing 29 and a distal end away from the housing 29. The cross-sectional area of the distal end of the protruding column 295 can be larger than that of the proximal end of the protruding column 295, so that the distal end of the protruding column 295 can block the pipeline and reduce the possibility that the pipeline falls off the protruding column 295. In some examples, the washer 24 further includes the brush head 241 described in the above example, and the protruding column 295 can be provided with a slot or a buckle for positioning the brush head 241, and the brush head 241 can be locked on the protruding column 295 when the washer 24 is not needed. When the wet cleaner 20 needs to be installed on the base 10, the brush head 241, the protruding column 295 and the pipeline on the protruding column 295 can be directly stored in the accommodating recess 171 together.

[0200]Referring to FIGS. 1, 2 and 3, on the basis of the above-described base station 100, the disclosure further describes an example of a robot system including the cleaning device 200 configured to clean a surface and the base station 100 in any of the above examples. The base station 100 has a docking part 11, and the cleaning device 200 can be docked at the docking part 11 (e.g., a docking port).

[0201]The cleaning device 200 can move on the surface. For example, the cleaning device 200 can move on the surface according to a preset trajectory, and the cleaning device 200 can clean the surface during moving. The docking part 11 may be a supporting platform disposed on the base 10 or a hollow area recessed on the base station 100. For example, when the cleaning device 200 is docked at the docking part 11, the base station 100 can be configured to charge and clean the cleaning device 200. The cleaning device 200 in the disclosure can be at least one of devices that can be configured to clean the surface, such as a sweeping robot, a vacuum cleaner, a vacuum and mopping robot, or a scrubber.
