DETAILED DESCRIPTION

[0033]To make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure is further described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are merely some rather than all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0034]It should further be noted that, the terms “comprise”, “include” and any other variants thereof are intended to cover non-exclusive inclusion, so that a commodity or an apparatus that includes a series of elements includes not only these elements but also other elements that are not expressly listed, or also includes elements inherent to this commodity or apparatus. Without more restrictions, an element defined by the phrase “including a . . . ” does not exclude the presence of another same element in a commodity or an apparatus that includes the element.

[0035]In the art, a cleaning device, for example, a floor scrubber, generally includes a device body and a cleaning base body. The cleaning device is generally provided with a water recycling tank, for example, a waste water tank and a cleaning liquid tank (e.g., a clean water tank), and a main fan used for suction. The cleaning base body includes one, two, or more cleaning brushrolls used for scrubbing. Cleaning liquid, for example, water, is dispensed onto the cleaning brushroll having fluff and/or onto a surface to be cleaned through a built-in water pipe. The cleaning brushroll rotates at a high speed to mop the surface to be cleaned. At the same time, a negative pressure is formed in a device air duct of the cleaning device by the main fan, enabling that waste water (that may include solid garbage) on the surface to be cleaned is sucked in through a waste water suction opening of the cleaning device and is pumped into the waste water tank. The foregoing waste water recycling path forms a part of the device air duct of the cleaning device.

[0036]After usage, the cleaning device is generally placed back onto a docking station to be supported by the docking station. Self-cleaning of the device, for example, washing of the cleaning brushroll and/or drying of the cleaning brushroll, may be performed on the docking station. A charging operation may also be performed on the docking station. In the related art, the docking station is usually of an integrated structure that has a relatively large size. In this case, a relatively large package needs to be equipped. In addition, an accommodation groove on a base of the docking station is configured to accommodate the cleaning base body of the cleaning device. The cleaning brushroll of the cleaning base body needs to be washed in the accommodation groove. Dirt exists in the accommodation groove, particularly, in a brushroll groove corresponding to the cleaning brushroll. The integrated structure of the docking station is not conductive to washing of the accommodation groove, particularly, the brushroll groove. Specifically, electronic components such as a charging wire, a circuit board and a fan exist in the docking station. Therefore, when the docking station of the integrated structure is washed, the electronic components have the risk of wading. In addition, because the size of the integrated structure is too large, the integrated structure is not conductive to cleaning.

[0037]The present disclosure provides a docking station. The docking station is configured to support a cleaning device and includes a station body and a detachable tray. The station body includes a base tray and a support base disposed on the base tray. The support base is configured to support a device body of the cleaning device. The detachable tray is configured to be detachably connected with the base tray. The detachable tray is connected to the base tray to form an accommodation groove. The accommodation groove is configured to accommodate a cleaning base body of the cleaning device. The detachable tray is provided with a brushroll groove configured to accommodate a cleaning brushroll of the cleaning base body. The detachable tray further includes a water blocking rib(s) disposed on one side or two sides of the brushroll groove.

[0038]In the present disclosure, the docking station includes the station body and the detachable tray. The detachable tray is detachably connected to the base tray of the station body, which can reduce a package size of the docking station. In addition, the detachable tray may be demounted and separated from the station body, facilitating a user to clean the detachable tray. The detachable tray is provided with the brushroll groove and the water blocking ribs disposed on the two sides of the brushroll groove, so that when the cleaning device performs, on the docking station, an operation of washing the cleaning brushroll, cleaning liquid can be kept in the brushroll groove as much as possible, thereby avoiding the cleaning liquid to be spilled into another portion of the accommodation groove.

[0039]The followings describe optional embodiments of the present disclosure with reference to the accompanying drawings.

[0040]FIG. 1 is a schematic structural diagram of a docking station provided by some embodiments of the present disclosure, where the docking station is in a connected state. FIG. 2 is a schematic structural diagram of a docking station provided by some embodiments of the present disclosure, where the docking station is in a connected state. The docking station shown in FIG. 2 and the docking station shown in FIG. 1 are taken from different viewing angles. FIG. 3 is a schematic structural diagram of a docking station provided by some embodiments of the present disclosure, where the docking station is in a demounted state. FIG. 4 is a schematic structural diagram of a docking station provided by some embodiments of the present disclosure, where the docking station is in a demounted state. The docking station shown in FIG. 4 and the docking station shown in FIG. 3 are taken from different viewing angles. Some embodiments of the present disclosure provide a docking station 10. The docking station 10 is configured to support a cleaning device. For example, the cleaning device is a floor scrubber. After finishing a cleaning operation, the floor scrubber may be placed back onto the docking station 10 for supporting. Various operations such as charging, washing a cleaning brushroll, and/or drying the cleaning brushroll may be performed on the docking station.

[0041]As shown in FIG. 1 to FIG. 4, the docking station 10 includes a station body 13 and a detachable tray 111 that are detachably connected with each other. Specifically, the station body 13 includes a base tray 112 and a support base 12. The support base 12 is disposed on the base tray 112. For example, the support base 12 extends from a surface of the base tray 112 along a direction substantially perpendicular to the base tray 112 and away from the base tray 112. The support base 12 and the base tray 112 may be of an integrated structure or may be of separated structures. The support base 12 is configured to support a device body of the cleaning device. When the cleaning device is placed on the docking station 10, the support base 12 supports the device body of the cleaning device. The detachable tray 111 is configured to be detachably connected with the base tray 112, and the detachable tray 111 and the base tray 112 jointly form a base 11 of the docking station 10.

[0042]When the detachable tray 111 is connected to the base tray 112 to form the complete base 11, the base 11 is provided with an accommodation groove 14. The accommodation groove 14 is configured to accommodate a cleaning base body of the cleaning device. When the cleaning device is placed on the docking station 10, the base 11 supports and accommodates the cleaning base body of the cleaning device. The cleaning base body is at least partially accommodated in the accommodation groove 14 to facilitate a self-washing operation, on the docking station 10, of the cleaning brushroll on the cleaning base body, thereby removing stains on the cleaning brushroll.

[0043]The detachable tray 111 is provided with a brushroll groove 1111 configured to accommodate the cleaning brushroll of the cleaning base body. The detachable tray further includes water blocking ribs 1112 disposed on two sides of the brushroll groove. For example, the number of the brushroll groove 1111 is one or more and is matched with the number of the cleaning brushroll of the cleaning device. In other embodiments, one brushroll groove 1111 may correspond to one or more cleaning brushrolls. As shown in FIG. 1 to FIG. 3, there are, for example, two brushroll grooves 1111; and the two brushroll grooves 1111 are disposed in parallel. There are, for example, also two water blocking ribs 1112 that are disposed on two sides of the brushroll grooves 1111 respectively. The cleaning brushroll may perform a washing operation in the brushroll groove 1111 by using cleaning liquid. The water blocking rib 1112 is configured to block the cleaning liquid from spilling outwards from the brushroll groove 1111 when the cleaning brushroll performs a self-washing operation.

[0044]In the present disclosure, the detachable tray 111 is detachably connected to the base tray 112 of the station body 13. After being demounted, the detachable tray 111 and the base tray 112 can be placed in a more flexible manner, so that space can be utilized more properly. Therefore, the design flexibility of a package is higher. For example, a relatively small package may be used for the docking station 10 that is in the demounted state, thereby reducing package costs. In addition, for the brushroll groove in which dirt is easy to accumulate, because the detachable tray 111 may be demounted and separated from the station body 13, a user may wash the detachable tray 111 after the detachable tray 111 is demounted. This facilitates washing.

[0045]In some embodiments, as shown in FIG. 1 to FIG. 4, the base tray 112 includes a first fixing clamp piece 1121. The first fixing clamp piece 1121 extends from a side wall, namely, a connecting side wall, of the base tray 112 along a direction away from the support base 12. The connecting side wall is, for example, a side wall of the base tray 112 away from the support base 12. The detachable tray 111 includes a second fixing clamp piece 1113. The second fixing clamp piece 1113 is configured to be detachably matched and clamped with the first fixing clamp piece 1121, thereby enabling the detachable tray 111 to be connected to the base tray 112. With the above structure, the detachable tray 111 may be conveniently mounted to the base tray 112 or demounted from the base tray 112.

[0046]In some embodiments, as shown in FIG. 1 to FIG. 4, there are a plurality of first fixing clamp pieces 1121. The plurality of first fixing clamp pieces 1121 are uniformly disposed along a connecting side wall of the base tray 112, for example, the connecting side wall is a side wall of the base tray 112 away from the support base 12. There are a plurality of second fixing clamp pieces 1113. The plurality of second fixing clamp pieces 1113 are in a one-to-one correspondence with the plurality of first fixing clamp pieces 1121. Two or more pairs of the first fixing clamp pieces 1121 and the second fixing clamp pieces 1113 that are matched with each other can make the detachable tray 111 and the base tray 112 be connected firmly. After the detachable tray 111 and the base tray 112 are connected, their positions are relatively fixed.

[0047]In some embodiments, one of the first fixing clamp piece 1121 and the second fixing clamp piece 1113 includes a T-shaped clamping groove; the other one of the first fixing clamp piece 1121 and the second fixing clamp piece 1113 includes a T-shaped insert; and the T-shaped clamping groove and the T-shaped insert are configured to be matched and clamped with each other. In the present disclosure, the T-shaped clamping groove is a clamping groove having a specific structure. A section, in a plane perpendicular to a first direction, of the clamping groove is T-shaped, as shown in FIG. 3 and FIG. 4. For example, the first direction is a vertical direction Y. For example, the plane perpendicular to the first direction is a horizontal plane. In the present disclosure, the T-shaped insert is an insert having a specific structure. A section, in a plane perpendicular to a first direction, of the insert is T-shaped, as shown in FIG. 3 and FIG. 4. For example, the first direction is a vertical direction Y. For example, the plane perpendicular to the first direction is a horizontal plane.

[0048]In some embodiments, as shown in FIG. 3 and FIG. 4, the first fixing clamp piece 1121 includes a T-shaped clamping groove; and the second fixing clamp piece includes a T-shaped insert. In a process of connecting the detachable tray 111 to the base tray 112, the detachable tray 111 may be moved towards the base tray 112 along the first direction Y until the detachable tray 111 and the base tray 112 are connected together. For example, first, the station body 13 is placed on an operating surface, for example, a horizontal floor; then, the detachable tray 111 is moved towards the horizontal floor along the vertical direction from top to bottom; and the second fixing clamp piece 1113 is aligned and in plug-in connection with the corresponding first fixing clamp piece 1121. In a process of demounting the detachable tray 111 from the base tray 112, the detachable tray 111 may be moved away from the base tray 112 along the first direction Y. For example, when the docking station 10 is placed on an operating surface, for example, a horizontal floor, the detachable tray 111 is moved away from the base tray 112 along the vertical direction from bottom to top.

[0049]After the first fixing clamp piece 1121 and the second fixing clamp piece 1113 that have the specific structures are matched and in plug-in connection with each other, the base tray 112 and the detachable tray 111 can be prevented from moving relative to each other in a horizontal direction. This can further make the base tray 112 and the detachable tray 111 be firmly connected with each other.

[0050]In some embodiments, the base tray 112 includes a first positioning clamp piece 1122. The first positioning clamp piece 1122 is disposed on the connecting side wall of the base tray 112, for example, the side wall of the base tray 112 away from the support base 12. The detachable tray 111 further includes a second positioning clamp piece 1114 configured to be clamped with the first positioning clamp piece 1122, thereby connecting the detachable tray 111 and the base tray 112 in position. In a process of aligning and plug-in connection of the first fixing clamp piece 1121 and the second fixing clamp piece 1113, the first positioning clamp piece 1122 and the second positioning clamp piece 1114 are matched and clamped with each other, which indicates that the first fixing clamp piece 1121 and the second fixing clamp piece 1113 are connected in a plug-in manner in place, and that the base tray 112 and the detachable tray 111 are firmly connected together.

[0051]In an embodiment, the first positioning clamp piece 1122 is disposed on at least one of two ends of the connecting side wall of the base tray. For example, as shown in FIG. 1 to FIG. 4, the first positioning clamp piece 1122 is disposed on each of the two ends of the side wall, away from the support base, of the base tray.

[0052]In some embodiments, one of the first positioning clamp piece 1122 and the second positioning clamp piece 1114 includes a positioning clamp hole; and the other one of the first positioning clamp piece 1122 and the second positioning clamp piece 1114 includes a positioning snap. For example, as shown in FIG. 1 to FIG. 4, the first positioning clamp piece 1122 includes the positioning clamp hole, and the second positioning clamp piece 1114 includes the positioning snap. When the first positioning clamp piece 1122 and the second positioning clamp piece 1114 are matched and in a snap-fit connection, it indicates that the first fixing clamp piece 1121 and the second fixing clamp piece 1113 are connected to each other in a plug-in manner in place, and that the base tray 112 and the detachable tray 111 are connected in place to form the base 11.

[0053]In some embodiments, the detachable tray 111 includes a blocking arm 1115 that is disposed on at least one end of the brushroll groove 1111 and configured to prevent the cleaning brushroll of the cleaning device from slipping. After usage, the cleaning device is generally placed back onto the docking station to be supported by the docking station. The cleaning brushroll can be washed on the docking station. The cleaning brushroll is at least partially accommodated in the brushroll groove 1111. The self-washing operation of the cleaning brushroll is mainly performed in the brushroll groove. In the washing process, the cleaning brushroll needs to rotate. The blocking arm 1115 is disposed at the end of the brushroll groove and thus can prevent the cleaning brushroll from slipping.

[0054]In some embodiments, as shown in FIG. 1 to FIG. 4, the blocking arm 1115 has a greater height than a side wall of the accommodation groove 14.

[0055]FIG. 5 is a schematic structural diagram of a cleaning system provided by some embodiments of the present disclosure, where a cleaning device is supported by a docking station. FIG. 6 is a schematic structural diagram of a cleaning system provided by some embodiments of the present disclosure, where a cleaning device is separated from a docking station.

[0056]Some embodiments of the present disclosure further provide a cleaning device 20, for example, a floor scrubber. The cleaning device 20 is matched with the docking station 10. As shown in FIG. 5 and FIG. 6, the cleaning device 20 includes a cleaning base body 21, a device body 22 and a handle assembly 23. The device body 22 is disposed above the cleaning base body 21, and is movably connected to the cleaning base body 21, for example, pivotally connected to the cleaning base body 21. The handle assembly 23 is connected to an end of the device body 22 away from the cleaning base body 21 and is used for being grasped by a user during an operation. The user grasps the handle assembly 23, thereby controlling the cleaning base body 21 to execute a cleaning task on a surface to be cleaned, for example, on a floor.

[0057]In some embodiments, the device body 22 extends lengthwise. The handle assembly 23 is connected to an upper end of the device body 22. The cleaning base body 21 is connected to a lower end of the device body 22. The device body 22 is pivotally connected to the cleaning base body 21, enabling the handle assembly 23 and the device body 22 to rotate relative to the cleaning base body 21, thereby changing an operating angle and flexibly adjusting a washing posture. The cleaning base body 21 includes a cleaning component, for example, the cleaning brushroll 211, disposed at the bottom of the cleaning base body 21. Specifically, for example, the number of the cleaning brushroll 211 is one or more, for example, two or three. The cleaning brushroll 211 can rotate at a high speed to mop a floor.

[0058]In some embodiments, as shown in FIG. 5 and FIG. 6, the cleaning device 20, for example, a floor scrubber, further includes a clean water tank 26 and a waste water tank 25, both of which are, for example, disposed on the device body 22. The clean water tank 26 accommodates cleaning liquid, for example, cleaning water, and may provide the cleaning water for the cleaning brushroll 211 through a clean water pipeline to wet a surface of the cleaning brushroll 211, thereby enabling the cleaning brushroll 211 to perform wet cleaning on the surface to be cleaned. The waste water tank 25 is configured to accommodate recycled waste water. When the cleaning brushroll 211 performs wet cleaning, waste water is generated on the surface that is cleaned. The waste water may be recycled into the waste water tank 25 through a waste water recycling pipeline.

[0059]In some embodiments, as shown in FIG. 5 and FIG. 6, after finishing a cleaning operation, the cleaning device 20 is generally placed on the docking station 10. The docking station 10 supports and fixes the cleaning device 20. With reference to FIG. 1 to FIG. 6, in some embodiments, an end of the support base 12 away from the base tray 112 is provided with a support groove 121. The support groove 121 is configured to accommodate a part of the device body 22 of the cleaning device 20 to support the device body 22. For example, the support groove 121 is configured to accommodate an end of the device body 22 of the cleaning device 20 away from the handle assembly 23. When the cleaning device 20 is placed on the docking station 10 after finishing the cleaning operation, the support groove 121 supports the device body 22, the accommodation groove on the base 11 accommodates and supports the cleaning base body 21 of the cleaning device 20, and the cleaning brushroll 211 on the cleaning base body 21 is accommodated in the brushroll groove 1111.

[0060]When the cleaning device 20 is supported by the docking station 10, the cleaning device 20 may further perform maintenance operations such as charging, self-cleaning and drying. In some embodiments, as shown in FIG. 1 to FIG. 6, the docking station 10 may include a first charging/communication interface; the cleaning device 20 may include a second charging/communication interface; and the first charging/communication interface is matched and connected with the second charging/communication interface, thereby implementing a charging/communication function between the cleaning device 20 and the docking station 10. The charging/communication function herein is at least one of a charging function or a communication function. In the present disclosure, the character “/” denotes and/or.

[0061]In some embodiments, the first charging/communication interface includes at least one first charging/communication terminal. The at least one first charging/communication terminal is a female terminal or a male terminal. For example, when the first charging/communication terminal is the female terminal, the second charging/communication interface on the cleaning device 20 is correspondingly provided with a matched male terminal; or when the first charging/communication terminal is the male terminal, the second charging/communication interface on the cleaning device 20 is correspondingly provided with a matched female terminal. When the male terminal and the female terminal that are matched with each other are disposed on the docking station 10 and the cleaning device 20 respectively, the cleaning device 20 is enabled to have a good electrical path when performing a maintenance operation. In some embodiments, there may be two or more first charging/communication terminals. The plurality of first charging/communication terminals may be arranged regularly. All the first charging/communication terminals may be terminals of the same type, for example, charging terminals, communication terminals, or time division multiplexing composite terminals of charging terminals and communication terminals. Alternatively, some of the first charging/communication terminals are charging terminals, and the other first charging/communication terminals are communication terminals.

[0062]With reference to FIG. 1 to FIG. 6, by taking that both the first charging/communication interface and the second charging/communication interface are charging interfaces as an example, the first charging interface 122 is disposed in the support groove 121, and the first charging interface 122 is configured to be matched and connected with the second charging interface on the device body 22, thereby charging the device body 22.

[0063]In the related art, the cleaning device may be placed back onto the docking station for charging. However, a charging terminal in a charging interface on the docking station is usually exposed outside, and thus is easily affected by moisture in an external environment. As a result, a charging path becomes faulty. In addition, because the charging terminal is exposed outside, in a case that the user spills water onto the charging terminal by accident during usage, an operating circuit is prone to short circuit if accumulated water is not removed timely. As a result, the device is damaged.

[0064]To resolve this problem, some embodiments of the present disclosure further provide a docking station. The docking station is configured to support a cleaning device, and charge the cleaning device and/or communicate with the cleaning device. The docking station includes: a base configured to support a cleaning base body of the cleaning device, and a support base disposed on the base and configured to support a device body of the cleaning device. The support base includes a first charging/communication interface. The first charging/communication interface includes: a first charging holder provided with a cavity, a female/male terminal disposed in the cavity and configured to be in plug-in connection with a male/female terminal on the cleaning device, and a water-proof layer, for example, a water-proof flexible plastic layer coating at least a part of the first charging holder to protect the female/male terminal. In the present disclosure, the water-proof flexible plastic layer is used to protect a female charging terminal in the cavity, thereby protecting the female charging terminal from being affected by external moisture and preventing the female charging terminal from being in contact with electrically conductive liquid.

[0065]The following embodiment is described by taking that the first charging/communication interface is a first charging interface, the second charging/communication interface is a second charging interface, the female/male terminal is a female charging terminal, and the male/female terminal is a male charging terminal as an example.

[0066]FIG. 7 is a schematic structural diagram of a docking station provided by some embodiments of the present disclosure, where the docking station is in a connected state. The docking station shown in FIG. 7 and the docking stations shown in FIG. 1 and FIG. 2 are taken from different viewing angles. FIG. 8 is a schematic enlarged diagram of a region M in FIG. 7. FIG. 9 is a sectional view of a part of the region M shown in FIG. 8. FIG. 10 is a schematic enlarged diagram of a part of FIG. 9.

[0067]With reference to FIG. 1 to FIG. 10, some embodiments of the present disclosure provide a docking station 10. The docking station 10 supports the cleaning device 20 and charges the cleaning device 20. The docking station 10 includes a base 11 and a support base 12. The base 11, for example, is provided with an accommodation groove 14. The accommodation groove 14 is configured to accommodate a cleaning base body 21 of the cleaning device 20. The support base 12 is disposed on the base 11 and is configured to support a device body 22 of the cleaning device 20. The support base 12, for example, extends from an upper surface of the base 11 along a direction substantially perpendicular to the base 11 and away from the base 11.

[0068]As shown in FIG. 1 to FIG. 10, the support base 12 includes a first charging interface 122 that is configured to be connected to a second charging interface on the cleaning device 20, thereby charging the cleaning device 20. The first charging interface 122 includes a first charging holder 1221, a female charging terminal 1222 and a water-proof flexible plastic layer 1223. For example, the first charging interface 122 is disposed in a support groove 121 of the support base 12. The first charging interface 122 extends from a bottom of the support groove 121 along a direction away from the base 11. The second charging interface on the cleaning device 20, for example, is at an end of the device body 22 away from the handle assembly 23. When the cleaning device 20 is placed back onto the docking station 10 for supporting, the support base 12 supports the device body 22, the device body 22 is partially accommodated in the support groove 121, and the first charging interface 122 is connected with the second charging interface on the cleaning device 20, thereby performing a charging operation.

[0069]The first charging holder 1221 is provided with a cavity 12211. The female charging terminal 1222 is disposed in the cavity 12211 and is configured to be in plug-in connection with a male charging terminal of the second charging interface on the cleaning device 20, thereby charging the cleaning device 20. The water-proof flexible plastic layer 1223 coats at least a part of the first charging holder 1221 to protect the female charging terminal 1222, thereby avoiding the following problem to ensure charging performance of the first charging interface 122: external moisture or liquid is in contact with the female charging terminal 1222 as the female charging terminal 1222 is directly exposed outside.

[0070]In some embodiments, as shown in FIG. 1 to FIG. 10, the cavity 12211 is provided with a cavity inlet 122111. The cavity inlet 122111 is, for example, disposed at an end of the cavity 12211 away from the base 11, and configured to guide the male charging terminal into the cavity 12211 for plug-in connection with the female charging terminal 1222. The cavity inlet 122111 is, for example, a structure that gradually broadens in a direction away from the cavity, so that the male charging terminal can be conveniently guided into the cavity 12211.

[0071]In some embodiments, the water-proof flexible plastic layer 1223 includes a water-proof flexible plastic head 12231. The water-proof flexible plastic head 12231 is disposed on a side of the cavity 12211 away from the base 11. The water-proof flexible plastic head 12231 is configured to be switchable between an open state and a closed state.

[0072]When the cleaning device 20 is supported by the docking station 10, the male charging terminal presses the water-proof flexible plastic head 12231 to make the water-proof flexible plastic head 12231 be in the open state, and the male charging terminal passes through the water- proof flexible plastic head 12231 and enters the cavity 12211 to be in plug-in connection with the female charging terminal 1222. When the cleaning device 20 is not supported by the docking station 10, the water-proof flexible plastic head 12231 is in the closed state to protect the female charging terminal 1222 in the cavity 12211.

[0073]The water-proof flexible plastic head 12231 is made of an elastic material and, for example, is provided with a notch, such as a cross-shaped notch. Under the action of no external force, the water-proof flexible plastic head is in the closed state. When the cleaning device 20 is placed on the docking station 10 and supported by the docking station 10, the male charging terminal of the cleaning device 20 is abutted against and exerts pressure on the water-proof flexible plastic head 12231, enabling the water-proof flexible plastic head 12231 to be in the open state. The male charging terminal may pass through the water-proof flexible plastic head 12231 to enter the cavity 12211 and be in plug-in connection with the female charging terminal 1222, thereby forming an electrical path for charging the cleaning device 20. In this case, a notch wall of the water-proof flexible plastic head 12231 is tightly attached to a side wall of the male charging terminal, which prevents intrusion of external liquid such as water, and can also implement sealing and water-proof functions in a charging process. It may be conceivable that the water-proof flexible plastic layer may also be made of a material that has similar properties as the flexible plastic, and the similar properties refer to being water proof and provided with elasticity.

[0074]In some embodiments, there may be one or more female charging terminals 1222. For example, the plurality of female charging terminals 1222 may be arranged regularly. As shown in FIG. 7 to FIG. 10, four female charging terminals 1222 are uniformly arranged in a row. In other embodiments, the plurality of female charging terminals 1222 may also be arranged in two or more rows. There may also be one or more cavities 12211 and one or more water-proof flexible plastic heads 12231. The cavities 12211 and the water-proof flexible plastic heads 12231 are in one-to-one correspondence with the female charging terminals 1222 respectively.

[0075]In some embodiments, as shown in FIG. 1 to FIG. 10, the first charging interface 122 further includes a guide pillar 1224 that is disposed on the first charging holder 1221. For example, the guide pillar 1224 extends from the first charging holder 1221 towards a direction away from the base 11. The guide pillar 1224 is configured to be inserted into a guide hole of the cleaning device 20, enabling the female charging terminal 1222 and the male charging terminal to be aligned with each other, thereby facilitating accurate connecting between the female charging terminal 1222 and the male charging terminal.

[0076]In some embodiments, as shown in FIG. 7 to FIG. 10, the first charging holder 1221 includes a charging holder body 12212 and a protruding portion 12213. The protruding portion 12213 is disposed on the charging holder body 12212. The cavity 12211 extends from an interior of the charging holder body 12212 into the protruding portion 12213. The guide pillar 1224 is also disposed on the charging holder body 12212 and is spaced from the protruding portion 12213. In some embodiments, the number of the guide pillar 1224 is one or more, for example, two. For example, the two guide pillars 1224 are disposed on two sides of the protruding portion 12213 respectively, and correspond to two guide holes of the cleaning device 20 respectively. Limitations to shapes of the guide pillar and the guide hole are not described. Only the following is indicated: the guide pillar and the guide hole are of a convex structure and a concave structure respectively, and are matched with each other. In some embodiments, the guide pillar may be a protrusion of any shape, such as a cylinder, a circular cone or a frustum. Accordingly, the guide hole is designed, based on the shape of the guide pillar, to be a groove having a matched shape.

[0077]In some embodiments, as shown in FIG. 7 to FIG. 10, the guide pillar 1224 is parallel to the cavity 12211. The guide pillar 1224 has a greater length than the protruding portion 12213. For example, in the extending direction of the guide pillar 1224, an end of the guide pillar 1224 away from the first charging holder 1221 is farther away from the base 11 than an end of the water-proof flexible plastic head 12231 away from the first charging holder 1221. Based on such arrangements, in a process of connecting the first charging interface 122 of the docking station 10 with the second charging interface of the cleaning device 20 for charging, before the male charging terminal is in contact with the female charging terminal 1222, the guide pillar 1224 may be inserted into the guide hole of the cleaning device 20 for guiding of alignment, enabling the female charging terminal 1222 and the male charging terminal to be aligned with each other.

[0078]This avoids damage to a charging connector caused by misplacement of the charging terminals, repeated trials, or the like.

[0079]FIG. 11 is a schematic diagram of a partial structure of a device body of a cleaning device provided by some embodiments of the present disclosure. The partial structure is a partial structure of the cleaning device 20 shown in FIG. 6 which is a bottom view. FIG. 12 is a schematic structural diagram of a section on which a first charging/communication interface is in plug-in connection with a second charging/communication interface provided by some embodiments of the present disclosure.

[0080]As shown in FIG. 1 to FIG. 12, the present disclosure provides a cleaning device 20. The cleaning device 20 is configured to be supported by the docking station 10 for charging, and includes a cleaning base body 21 and a device body 22. The device body 22 is disposed above the cleaning base body 21, and is movably connected to the cleaning base body 21, for example, pivotally connected to the cleaning base body 21. The cleaning base body 21 includes a cleaning brushroll 211. The cleaning device 20 may further include a handle assembly 23 that is connected to an end of the device body 22 away from the cleaning base body 21 and is used for being grasped by a user during an operation.

[0081]The device body 22 includes a second charging interface 221. The second charging interface 221 is, for example, disposed at an end of the device body 22 away from the handle assembly 23. The second charging interface 221 includes a second charging holder 2211 and a male charging terminal 2212. The male charging terminal 2212 is disposed on the second charging holder 2211 and is configured to be in plug-in connection with the female charging terminal 1222 on the docking station 10, thereby forming a charging path for charging the cleaning device 20.

[0082]In some embodiments, the second charging holder 2211 is provided with a recess portion 22111; the male charging terminal 2212 is at least partially disposed in the recess portion 22111; and the male charging terminal 2212 extends from a bottom surface of the recess portion 22111 towards a direction away from the device body 22. When the cleaning device 20 is placed on the docking station 10, the protruding portion 12213 of the first charging holder 1221 is at least partially inserted into the recess portion 22111. The shape of the protruding portion 12213 is matched with that of the recess portion 22111, enabling the first charging interface 122 and the second charging interface 221 to be firmly connected with each other.

[0083]In some embodiments, the second charging holder 2211 is provided with a guide hole 22112, and the guide hole 22112 is configured to accommodate the guide pillar 1224 of the docking station 10, enabling the male charging terminal 2212 and the female charging terminal 1222 to be aligned with each other. This avoids damage to a charging connecter caused by misplacement of the charging terminals, repeated trials, or the like. In some embodiments, the number of the guide hole 22112 corresponds to that of the guide pillar 1224, and may be one or more, for example, two. For example, the two guide holes are disposed on two sides of the recess portion 22111 respectively.

[0084]In some embodiments, the second charging interface 221 further includes a reset spring 2213. The reset spring 2213 is disposed in the guide hole 22112 and is configured to push against the guide pillar 1224, thereby enabling the guide pillar 1224 to trend to be separated from the guide hole 22112. Due to the arrangement of the reset spring, the following problem can be avoided: it is difficult to separate the second charging interface 221 from the first charging interface 122. Specifically, the following problem is prevented: the second charging interface 221 is clamped tightly with the first charging interface 122, and thus it is difficult to separate the cleaning device 20 from the docking station 10. When the cleaning device 20 is placed on the docking station 10 for charging, the reset spring is enabled to be in a compressed state under the action of the self-weight of the cleaning device 20, and at the same time, the second charging interface 221 is enabled to be in plug-in connection with the first charging interface 122 in place, so that poor connection between charging terminals can be avoided. When a user takes the cleaning device 20 down from the docking station, the reset spring may provide a force whose direction is opposite to that of gravity of the cleaning device 20, which can overcome a frictional force generated due to tight clamping between the male charging terminal 2212 and the female charging terminal 1222. Therefore, the user can separate the cleaning device 20 from the docking station 10 by exerting a relatively small force.

[0085]In some embodiments, an end of the male charging terminal 2212 away from the second charging holder 2211 is of a structure that tapers in a direction away from the second charging holder 2211, facilitating that when the second charging interface 221 is connected with the first charging interface 122, the male charging terminal 2212 presses the notch of the water-proof flexible plastic head 12231, thereby enabling the water-proof flexible plastic head 12231 to be in the open state. Therefore, the male charging terminal 2212 can enter the cavity 12211 to be in plug-in connection with the female charging terminal 1222. When the male charging terminal 2212 does not press the water-proof flexible plastic head 12231, the notch of the water-proof flexible plastic head 12231 is in the closed state, which can prevent external water or moisture from entering the cavity 12211 and protect the female charging terminal 1222. When the male charging terminal 2212 having the foregoing structure presses the water-proof flexible plastic head 12231, the notch of the water-proof flexible plastic head 12231 is opened gradually. In addition, an inner wall of the notch is tightly attached to the male charging terminal 2212. This also implements a water-proof function.

[0086]In the present disclosure, the water-proof flexible plastic head 12231 that is switchable between the open state and the closed state is used to seal the cavity 12211 inlet that accommodates the female charging terminal 1222; and the water-proof flexible plastic head 12231 is made of an elastic material. Therefore, plug-in connection between the male charging terminal 2212 and the female charging terminal 1222 can be implemented conveniently, and the female charging terminal 1222 can be protected easily.

[0087]The female/male terminal is a female terminal and includes an elastic interface. The elastic interface is configured to accommodate at least a part of a male terminal. In some embodiments, as shown in FIG. 7 to FIG. 12, the female charging terminal 1222 includes an elastic interface 12221. The elastic interface 12221 is configured to accommodate a part of the male charging terminal 2212, enabling the female charging terminal 1222 to be tightly connected with a corresponding male charging terminal 2212. For example, the elastic interface 12221 includes a plurality of elastic plates, for example, two or more elastic plates. The plurality of elastic plates form an inlet of the elastic interface 12221 in a surrounding manner. The inlet allows the male charging terminal 2212 to be inserted in. The plurality of elastic plates trend to gather together, enabling the male charging terminal 2212 to be clamped tightly by the elastic plates after being inserted into the inlet of the elastic interface 12221. Specifically, the plurality of elastic plates take the shape of a curved arc-shaped surface. The elastic interface 12221 includes a tightening portion and an open portion that are close to the water-proof flexible plastic head 12231 sequentially. The tightening portion is configured to clamp the male charging terminal 2212, enabling the male charging terminal 2212 to be in good electrical contact with the female charging terminal 1222. The opening portion is gradually opened up in the direction towards the water-proof flexible plastic head 12231, for example, takes the shape of a horn mouth. The opening portion is aligned with the cavity inlet 122111, facilitating the male charging terminal 2212 to be inserted into the elastic interface 12221.

[0088]In some embodiments, as shown in FIG. 8, at least one of a pair of opposite side walls of the support groove 121 of the support base 12 is provided with a guide groove 1211. In some embodiments, each of the pair of side walls is provided with a guide groove 1211. As shown in FIG. 11, at least one of a pair of opposite side walls of the device body 22 of the cleaning device 20 is provided with a guide protrusion 222, for example, each of the pair of opposite side walls is provided with a guide protrusion 222. The guide protrusion 222 is disposed to be matched with the guide groove 1211. When the cleaning device 20 is placed back onto the docking station 10, the guide protrusion 222 is matched with the guide groove 1211. The guide protrusion 222 slides into the guide groove 1211, enabling the device body 22 of the cleaning device 20 to be aligned with the support groove 121 of the support base 12 of the docking station 10. This helps the device body 22 be accurately supported by the support base 12, thereby avoiding misplacement. In some embodiments, the guide groove 1211 extends, on a side wall of the support groove 121, from the top of the side wall towards the bottom of the side wall, and the width of the guide groove 1211 decreases gradually as the guide groove 1211 gradually approaches the bottom of the side wall. Such design facilitates increasing robustness of the support groove 121, into which the device body 22 is placed back, of the support base 12.

[0089]In some embodiments, the guide groove 1211 is matched with the guide protrusion 222 to form level-1 guided alignment; and the guide pillar 1224 is matched with the guide hole 22112 to form level-2 guided alignment. Due to the two levels of guided alignment, the device body 22 can be accurately placed back into the support groove 121 of the support base 12. This ensures that the male charging terminal 2212 can be in accurate plug-in connection with the female charging terminal 1222.
