[0051]The present invention is further described in detail hereinafter in conjunction with the accompanying drawings.

[0052]Please refer to FIGS. 1 to 3, a brush assembly 10 is provided according to an embodiment of the present invention, including a housing 100, a liquid waste tank 200 and a brush head 300.

[0053]The housing 100 includes a main inlet 121 and an accommodating chamber 110, and the main inlet 121 is in communication with the accommodating chamber 110. Specifically, the housing 100 is provided with a roller brush chamber 120 at a front portion thereof, the housing 100 is provided with the accommodating chamber 110 at a middle portion thereof, and the main inlet 121 is provided at the roller brush chamber 120 at a front portion of the accommodating chamber 110.

[0054]The liquid waste tank 200 includes a first inlet 210, which is generally provided on a front sidewall of the liquid waste tank 200, or may be provided through a top wall of the liquid waste tank 200. When the liquid waste tank 200 is placed in the accommodating chamber 110, the position of the first inlet 210 corresponds to the position of the main inlet 121, so that the first inlet 210 is in communication with the main inlet 121. A retaining element 230 is also provided in the liquid waste tank 200, and the retaining element 230 at least partially restricts the movement of liquid waste from the first inlet 210. More specifically, after the liquid waste enters the liquid waste tank 200 from the first inlet 210, the retaining element 230 has a restricting effect on the liquid waste, thereby effectively restricting the movement of the liquid waste in the liquid waste tank 200, so that the liquid waste is kept in the liquid waste tank 200.

[0055]The brush head 300 is arranged near the main inlet 121, more specifically, the brush head is cylindrical and is rotatably arranged in the roller brush chamber 120. The brush head 300 acts on the surface to be cleaned during rotation, such as a floor. The brush head 300 causes the liquid waste on the surface to be cleaned to flow along the roller brush chamber 120 to the main inlet 121, and enters the liquid waste tank 200 through the main inlet 121 and the first inlet 210, thereby the collection of liquid waste is completed by the liquid waste tank 200.

[0056]It can be understood that a retaining element 230 is arranged through a side sidewall of the liquid waste tank 200, and the retaining element 230 can effectively restrict the movement of liquid waste in the liquid waste tank 200. In this way, even if the brush assembly 10 shakes during operation, with the retaining element 230, the liquid waste tank 200 can effectively prevent liquid waste from overflowing from the first inlet 210, thereby ensuring that the brush assembly 10 can work effectively.

[0057]Moreover, during the use of the brush assembly 10, since the retaining element 230 can effectively prevent the liquid waste from overflowing from the first inlet 210, the user does not need to frequently replace the liquid waste tank 200 or clean the liquid waste in the liquid waste tank 200 to prevent the liquid waste from overflowing when using the brush assembly 10, making it more convenient to use the brush assembly 10.

[0058]In addition, when the user needs to replace or clean the liquid waste tank 200, even if there is a large amount of liquid waste in the liquid waste tank 200, with the retaining element 230 being provided in the liquid waste tank 200, the movement of the liquid waste can be effectively restricted. Therefore, when the user disassembles and replaces the liquid waste tank 200, there is no need to worry that the wastewater in the liquid waste tank 200 will overflow from the first inlet 210, thereby facilitating the replacement of the liquid waste tank 200.

[0059]It should be noted that the brush assembly 10 in the present application is not limited to dealing with the liquid waste, but can also be applied to other scenarios. Therefore, the retaining element 230 in the present application is not limited to restricting the movement of liquid waste such as liquid water in the liquid waste tank 200, but can also be used to restrict the movement of other types of liquid waste.

[0060]In some embodiments, referring to FIGS. 2 and 3, the housing 100 further includes an air suction passage 130, which is usually arranged at a rear side of the accommodating chamber 110, and the specific arrangement is determined according to actual needs. The air suction passage 130 forms a suction opening 131 at a rear side of an inner wall of the accommodating chamber 110, so that the air suction passage 130 is in communication with the accommodating chamber 110. In addition, the liquid waste tank 200 is provided with a first outlet 220 at a position away from the first inlet 210. When the liquid waste tank 200 is placed in the accommodating chamber 110, the position of the first outlet 220 corresponds to the position of the suction opening 131. Therefore, the first outlet 220 is in communication with the suction opening 131, and accordingly, the liquid waste tank 200 is in communication with the air suction passage 130.

[0061]In specific application, the air suction passage 130 is in communication with an external cleaning host 610 (please refer to FIG. 6). When the cleaning host 610 is started, the cleaning host 610 exerts a suction force on the liquid waste tank 200 through the air suction passage 130, the liquid waste tank 200 is under a negative pressure inside, thus generating the suction force in the roller brush chamber 120. Therefore, when the brush head 300 rolls to brush the surface to be cleaned, the liquid waste enters the liquid waste tank 200 through the main inlet 121 and the first inlet 210 in sequence under the action of the suction force. Because the inner sidewall of the liquid waste tank 200 is provided with the retaining element 230, after the liquid waste is sucked into the liquid waste tank 200, it can be effectively retained in the liquid waste tank 200 under the restriction of the retaining element 230, which prevents the liquid waste from entering the cleaning host 610 along with the airflow, thereby ensuring the safety of using the cleaning host 610. Meanwhile, the retaining element 230 effectively prevents liquid waste from entering the air suction passage 130, which prevents the liquid waste from contaminating the air suction passage 130, thereby ensuring the cleanliness of the brush assembly 10 during use.

[0062]In other possible embodiments, instead of the air suction passage 130, a guide plate (not shown in the figures) is provided on the inner side of the roller brush chamber 120. One end of the guide plate is located on one side of the brush head 300, and the other end extends to the main inlet 121. In this way, the brush head 300 rotates to transfer the liquid waste to the guide plate, the liquid waste flows along the guide plate to the main inlet 121, and flows into the liquid waste tank 200 through the first inlet 210, to realize collection of the liquid waste.

[0063]In a possible embodiment, referring to FIGS. 2 and 3, the retaining element 230 is an absorbent pad attached to the inner wall of the liquid waste tank 200. The absorbent pad is made of superabsorbent polymers, a sponge or nylon. It can be understood that the retaining element 230 employs the absorbent pad attached to the inner wall of the liquid waste tank 200, in this way, the retaining element 230 has a good retention effect on the liquid waste, thereby effectively preventing the liquid waste from overflowing from the first inlet 210 and the first outlet 220, and also effectively preventing the liquid waste from entering the air suction passage 130 along with the airflow.

[0064]Moreover, the retaining element 230 employs the absorbent pad, and the absorbent pad has a simple structure and can be arranged on the inner sidewall of the liquid waste tank 200 conveniently, which is conducive to mass production of the liquid waste tank 200.

[0065]In addition, the cost of the absorbent pad is low, and accordingly, the cost of the liquid waste tank 200 is also effectively reduced, and the liquid waste tank 200 can be used as a disposable consumable.

[0066]In other possible embodiments, the retaining element 230 is a baffle (not shown in the figure) arranged in the liquid waste tank 200, where the baffle may be a structure integrally formed with the liquid waste tank 200, or a structure additionally arranged in the liquid waste tank 200, which is not specifically limited in the present application. It can be understood that, with the arrangement of the baffle, after the liquid waste enters the liquid waste tank 200, the baffle serves to block the liquid waste entering the liquid waste tank 200, to retain the liquid waste in the liquid waste tank 200.

[0067]In order to reduce the liquid waste from entering the air suction passage 130, in a first possible embodiment, the first inlet 210 is provided through a sidewall of the liquid waste tank 200, and the first outlet 220 is provided through a top wall of the liquid waste tank 200. With this arrangement, after the liquid waste enters the liquid waste tank 200 from the first inlet 210 under the action of the suction force, the liquid waste is most likely to be tosses onto a side plate of the liquid waste tank 200 facing the first outlet 220, and the first outlet 220 is provided on the top of the liquid waste tank 200, which effectively reduces the liquid waste from entering the air suction passage 130 through the first outlet 220, thereby ensuring the cleanliness of the air suction passage 130.

[0068]In a second possible embodiment, the first inlet 210 and the first outlet 220 are both provided on the top of the liquid waste tank 200. With this arrangement, after the liquid waste enters the liquid waste tank 200 from the first inlet 210 under the action of the suction force, the liquid waste is most likely to be tossed onto a bottom of the liquid waste tank 200, and the first outlet 220 is provided on the top of the liquid waste tank 200, which effectively reduces the liquid waste from entering the air suction passage 130 through the first outlet 220, thereby ensuring the cleanliness of the air suction passage 130.

[0069]In a third possible embodiment, the first inlet 210 and the first outlet 220 are provided through opposite sidewalls of the liquid waste tank 200, and the first inlet 210 and the first outlet 220 are staggered. With such an arrangement, after the liquid waste enters the liquid waste tank 200 from the first inlet 210 under the action of the suction force, the liquid waste is most likely to be tossed onto the side plate of the liquid waste tank 200 facing the first outlet 220, while the position onto which the liquid waste is tossed and the position of the first outlet 220 are staggered with respect to each other, to effectively reduce the liquid waste from entering the air suction passage 130 through the first outlet 220, thereby ensuring the cleanliness of the air suction passage 130.

[0070]In some embodiments, referring to FIGS. 3 and 4, the retaining element 230 is an absorbent pad attached to the inner wall of the liquid waste tank 200. The absorbent pad may be provided on a bottom wall of the liquid waste tank 200, or on a side wall of the liquid waste tank 200; alternatively, the absorbent pad may also be provided on both the bottom wall and the side wall of the liquid waste tank 200 In a case that the absorbent pad is provided on the side wall of the liquid waste tank 200, the absorbent pad may be provided only on a part of the side wall of the liquid waste tank 200 instead on being attached to the entire side wall of the liquid waste tank 200, which can be provided according to actual needs. For example, when being applied to daily household floor cleaning, demands can be satisfied by providing the absorbent pad onto only a part of the sidewall of the liquid waste tank 200, which saves the cost of the liquid waste tank 200, and thus the liquid waste tank 200 is suitable for use as a disposable consumable.

[0071]Further, at least a sidewall of the liquid waste tank 200 facing the first inlet 210 is provided with the absorbent pad. Specifically, the first inlet 210 is provided at the sidewall of the liquid waste tank 200, and at least another sidewall of the liquid waste tank 200 facing the first inlet 210 is provided with the absorbent pad. In other words, the absorbent pad is attached to the side wall of the liquid waste tank 200 facing the first inlet 210. Alternatively, the first inlet 210 is provided on the top of the liquid waste tank 200, and at least the bottom of the liquid waste tank 200 is provided with the absorbent pad.

[0072]It can be understood that the absorbent pad is arranged at the position opposite to the first inlet 210. With this arrangement, after the liquid waste enters the liquid waste tank 200 from the first inlet 210 under the action of the suction force, the liquid waste is most likely to be tossed onto the absorbent pad, so that the liquid waste can quickly attach to the absorbent pad, which prevents the liquid waste from entering the air suction passage 130 along with the airflow, and thereby ensuring the cleanliness of the air suction passage 130.

[0073]In some embodiments, referring to FIGS. 1 to 3, the liquid waste tank 200 is configured to be detachably arranged in the accommodating chamber 110. For example, the accommodating chamber 110 is provided with buckle structures 140 at left and right sides thereof respectively, and left and right sidewalls of the liquid waste tank 200 are provided with snap-fit slots 240 respectively. Therefore, after the liquid waste tank 200 is placed in the accommodating chamber 110, the buckle structures 140 on both sides of the accommodating chamber 110 are simply snap-fitted into the snap-fit slots 240 respectively, and thus, the buckle structures 140 keep the liquid waste tank 200 inside the accommodating chamber 110. When the liquid waste tank 200 needs to be removed, the operator only needs to release the restriction of the buckle structure 140 on the liquid waste tank 200, and the user can easily replace the liquid waste tank 200 of the brush assembly 10 with a new liquid waste tank 200 to ensure the normal use of the brush assembly 10.

[0074]The liquid waste tank 200 is a disposable consumable, more specifically, the liquid waste tank 200 is a disposable liquid waste tank 200, and the user can flexibly replace the liquid waste tank 200 as needed. For example, each liquid waste tank 200 can be replaced by a new one after being used for one to three days, and accordingly, there is no need to reuse the liquid waste tank 200, which makes it more convenient to use the brush assembly 10.

[0075]In order to illustrate that the liquid waste tank 200 is a disposable consumable, in some embodiments, the liquid waste tank 200 is only provided with an inlet and outlet (the first inlet 210 and the first outlet 220 mentioned above). Specifically, the surface of the liquid waste tank 200 is only provided with the first inlet 210, or the surface of the liquid waste tank 200 is only provided with the first inlet 210 and the first outlet 220. Accordingly, the liquid waste tank 200 is not provided with a replacement port 250 or other openings for other purposes, such as for replacing the absorbent pad.

[0076]Further, the liquid waste tank 200 is a closed box that cannot be dismantled. Specifically, the liquid waste tank 200 is a closed box, that is, the bottom, sides and top of the liquid waste tank 200 are all closed, that is, the liquid waste tank 200 is provided with no other openings except for the inlet and outlet. Also, the liquid waste tank 200 is a non-dismantle box, and the liquid waste tank 200 is an integral closed structure, rather than a box formed by connecting multiple shells. As can be seen from the above, in this application, the liquid waste tank 200 adopts the one-piece box, and the liquid waste tank 200 is a disposable consumable. The user cannot replace the absorbent pad in the liquid waste tank 200, which further clearly illustrates that the brush assembly 10 adopts a disposable liquid waste tank 200. Accordingly, there is no need to reuse the liquid waste tank 200, which makes it more convenient to use the brush assembly 10.

[0077]Further illustrating from other angles that the liquid waste tank 200 is a disposable consumable, in some embodiments, the liquid waste tank 200 is a blow-molded box. It can be understood that the liquid waste tank 200 adopts a box formed by blow molding. In this way, the liquid waste tank 200 is a one-piece box, and the surface of the liquid waste tank 200 is only provided with the inlet and outlet. Accordingly, the liquid waste tank 200 cannot be provided with a replacement port 250 for replacing the absorbent pad. It can be seen that it is further clearly illustrated that the brush assembly 10 adopts a disposable liquid waste tank 200. Accordingly, there is no need to reuse the liquid waste tank 200, which makes it more convenient to use the brush assembly 10. Moreover, the liquid waste tank 200 is formed by blow molding, which makes it cost-effective and allows it to have a very thin thickness, making it suitable as a disposable consumable.

[0078]In other possible embodiments, referring to FIG. 5, the liquid waste tank 200 is a reusable box. Specifically, the liquid waste tank 200 is configured to be detachably arranged in the accommodating chamber 110. For example, the liquid waste tank 200 is snap-fitted to the accommodating chamber 110 of the housing 100. Meanwhile, the liquid waste tank 200 is provided with a replacement port 250, and the absorbent pad can be replaced though the liquid waste tank 200. The liquid waste tank 200 is usually provided with a sealing cover 260 at the replacement port 250, and the sealing cover 260 ensures the sealing effect of the liquid waste tank 200.

[0079]It can be understood that the liquid waste tank 200 is provided with the replacement port 250, and is detachably arranged in the brush assembly 10. When there is a lot of liquid waste in the liquid waste tank 200, and the retaining element 230 in the liquid waste tank 200 can no longer retain the liquid waste completely, at this time, the user can remove the liquid waste tank 200 from the brush assembly 10. After the liquid waste tank 200 is detached, the retaining element 230 can be replaced or cleaned through the replacement port 250, depending on actual needs. For example, if the retaining element 230 of the liquid waste tank 200 is an absorbent pad, by replacing the absorbent pad, the user can remount the liquid waste tank 200 to the brush assembly 10 for use. If the retaining element 230 of the liquid waste tank 200 is a baffle provided on the liquid waste tank 200, after detaching the liquid waste tank 200, the user only needs to clean the baffle through the replacement port 250, and the cleaned liquid waste tank 200 can be remounted in the brush assembly 10 for use.

[0080]In some embodiments, the housing 100 is provided with an opening in communication with the accommodating chamber 110, and the opening may be provided at the bottom of the brush assembly 10. In this way, it is equivalent that the liquid waste tank 200 is hidden on the inner side of the housing 100 when in use, making the appearance of the brush assembly 10 better. Alternatively, the opening may be provided at the top of the brush assembly 10. In this way, the liquid waste tank 200 can be replaced directly from the top of the brush assembly 10, making it more convenient to use the brush assembly 10.

[0081]In some embodiments, referring to FIGS. 2 and 3, the brush assembly 10 further includes a filter member 400, the filter member 400 may employ HEPA filter, etc., and the filter member 400 is arranged in the air suction passage 130. Besides, along a conveying direction of the air suction passage 130, the filter member 400 is folded and arranged in the air suction passage 130 in sequence. Of course, the filter member 400 may be filled in the air suction passage 130 in other ways, and the present application does not limit the filter member 400 to be filled in the air suction passage 130 only in a folded manner.

[0082]It is understandable that the filter member 400 is arranged in the air suction passage 130, when the airflow passes through the liquid waste tank 200, a small amount of dirt may still enter the air suction passage 130, especially dust or various tiny waste debris, etc. Therefore, with the filter member 400 being arranged in the air suction passage 130, the dirt contained in the airflow can be effectively filtered out to prevent the dirt from entering the cleaning host 610 along with the airflow, thereby ensuring the safety of the cleaning host 610.

[0083]Moreover, the filter member 400 is placed in the air suction passage 130 in a folded manner. In this way, the dirt contained in the airflow can be fully filtered out by the filter member 400. Meanwhile, the filter member 400 will not excessively affect the suction force of the cleaning host 610 on the liquid waste tank 200 through the air suction passage 130, thereby ensuring that the brush assembly 10 can fully suck the liquid waste brushed by the brush head 300.

[0084]It should be noted that, with the retaining element 230 being provided in the liquid waste tank 200, after the liquid waste enters the liquid waste tank 200 along with the airflow, the retaining element 230 limits the movement of the liquid waste in the wastewater, thereby preventing the liquid waste from flowing to the filter paper, and further preventing the liquid waste from excessively adhering to the filter paper. Therefore, the filter paper can keep a good air permeable performance, thereby ensuring that the cleaning host 610 maintains a good suction effect on the liquid waste tank 200 through the suction passage 130.

[0085]In a further embodiment, the first outlet 220 is arranged at the top of the liquid waste tank 200, and the suction opening 131 of the air suction passage 130 is just located above the first outlet 220, so that the first outlet 220 is in communication with the air suction passage 130, that is, the liquid waste tank 200 is in communication with the air suction passage 130. Meanwhile, at least part of the filter member 400 is located close to the first outlet 220, so that the above at least part of the filter member 400 is just located above the first outlet 220 to filter the airflow that has just entered the air suction passage 130.

[0086]It can be understood that the part of the filter member 400 is located just above the first outlet 220. In this way, when the liquid waste mixed with the airflow enters the air suction passage 130, the filter member 400 can effectively block the liquid waste at the position of the first outlet 220. In addition, because the first outlet 220 is provided at the top of the liquid waste tank 200, the liquid waste filtered out by the filter member 400 falls back into the liquid waste tank 200 through the first outlet 220 under its gravity. It can be seen that, the filter member 400 with the above arrangement can more effectively prevent the liquid waste from entering the air suction passage 130 and reduce the liquid waste from adhering to the surface of the filter member 400. In addition, the filter member 400 is filled at the suction opening 131 of the air suction passage 130 in a folded manner, which facilitates the liquid waste adhering to the filter member 400 to fall back into the liquid waste tank 200.

[0087]The present application further discloses a brush assembly 10. Referring to FIGS. 1 to 3, the brush assembly 10 includes a housing 100, a liquid waste tank 200 and a brush head 300.

[0088]The housing 100 includes a main inlet 121 and an accommodating chamber 110, and the main inlet 121 is in communication with the accommodating chamber 110; specifically, the housing 100 is provided with a roller brush chamber 120 a front portion thereof, and the housing 100 is provided with the accommodating chamber 110 at a middle portion thereof, and the main inlet 121 is provided at the roller brush chamber 120 at a front portion of the accommodating chamber 110.

[0089]The liquid waste tank 200 includes a first inlet 210, which is generally provided on the front sidewall of the liquid waste tank 200, or may be provided on the top of the liquid waste tank 200. When the liquid waste tank 200 is placed in the accommodating chamber 110, the position of the first inlet 210 is just the same as the position of the main inlet 121, so that the first inlet 210 is in communication with the main inlet 121. A retaining element 230 is also provided in the liquid waste tank 200, and the retaining element 230 at least partially restricts the movement of liquid waste from the first inlet 210. More specifically, after the liquid waste enters the liquid waste tank 200 from the first inlet 210, the retaining element 230 has a restricting effect on the liquid waste, thereby effectively restricting the movement of the liquid waste in the liquid waste tank 200, so that the liquid waste is kept in the liquid waste tank 200.

[0090]The brush head 300 is arranged near the main inlet 121, more specifically, the brush head is cylindrical and is rotatably arranged in the roller brush chamber 120. The brush head 300 acts on the surface to be cleaned during rotation, such as a floor. The brush head 300 causes the liquid waste on the surface to be cleaned to flow along the roller brush chamber 120 to the main inlet 121, and enters the liquid waste tank 200 through the main inlet 121 and the first inlet 210, thereby the collection of liquid waste is completed by the liquid waste tank 200.

[0091]The liquid waste tank 200 is detachably arranged in the accommodating chamber 110, so that an unused liquid waste tank 200 can be replaced for the brush assembly 10. The liquid waste tank 200 is a disposable box.

[0092]Specifically, the liquid waste tank 200 is configured to be detachably arranged in the accommodating chamber 110. For example, the accommodating chamber 110 is provided with buckle structures 140 at left and right sides thereof respectively, and left and right sidewalls of the liquid waste tank 200 are provided with snap-fit slots 240 respectively. Therefore, after the liquid waste tank 200 is placed in the accommodating chamber 110, the buckle structures 140 on both sides of the accommodating chamber 110 are simply snap-fitted into the snap-fit slots 240 respectively, and thus, the buckle structures 140 keep the liquid waste tank 200 inside the accommodating chamber 110. When the liquid waste tank 200 needs to be removed, the operator only needs to release the restriction of the buckle structure 140 on the liquid waste tank 200, and the user can easily replace the liquid waste tank 200 of the brush assembly 10 with a new liquid waste tank 200 to ensure the normal use of the brush assembly 10.

[0093]The liquid waste tank 200 is a disposable consumable, more specifically, the liquid waste tank 200 is a disposable liquid waste tank 200, that is, a non-recyclable box. For example, each liquid waste tank 200 can be replaced by a new one after being used for one to three days, and accordingly, there is no need to reuse the liquid waste tank 200, which makes it more convenient to use the brush assembly 10.

[0094]In order to illustrate that the liquid waste tank 200 is a disposable consumable, in some embodiments, the liquid waste tank 200 is only provided with the inlet and outlet. Specifically, the surface of the liquid waste tank 200 is only provided with the first inlet 210, or the surface of the liquid waste tank 200 is only provided with the first inlet 210 and the first outlet 220. Accordingly, the liquid waste tank 200 is not provided with a replacement port 250 or other openings for other purposes, such as for replacing the absorbent pad.

[0095]Further, the liquid waste tank 200 is a closed box that cannot be dismantled. Specifically, the liquid waste tank 200 is a closed box, that is, the bottom, sides and top of the liquid waste tank 200 are all closed, that is, the liquid waste tank 200 is provided with no other openings except for the inlet and outlet. Also, the liquid waste tank 200 is a non-dismantle box, and the liquid waste tank 200 is an integral closed structure, rather than a box formed by connecting multiple shells. As can be seen from the above, in this application, the liquid waste tank 200 adopts the one-piece box, and the liquid waste tank 200 is a disposable consumable. The user cannot replace the absorbent pad in the liquid waste tank 200, which further clearly illustrates that the brush assembly 10 adopts a disposable liquid waste tank 200. Accordingly, there is no need to reuse the liquid waste tank 200, which makes it more convenient to use the brush assembly 10.

[0096]Further illustrating from other angles that the liquid waste tank 200 is a disposable consumable, in some embodiments, the liquid waste tank 200 is a blow-molded box. It can be understood that the liquid waste tank 200 adopts a box formed by blow molding. In this way, the liquid waste tank 200 is a one-piece box, and the surface of the liquid waste tank 200 is only provided with the inlet and outlet. Accordingly, the liquid waste tank 200 cannot be provided with a replacement port 250 for replacing the absorbent pad. It can be seen that it is further clearly illustrated that the brush assembly 10 adopts a disposable liquid waste tank 200. Accordingly, there is no need to reuse the liquid waste tank 200, which makes it more convenient to use the brush assembly 10. Moreover, the liquid waste tank 200 is formed by blow molding, which makes it cost-effective and allows it to have a very thin thickness, making it suitable as a disposable consumable.

[0097]In some embodiments, referring to FIGS. 2 to 4, the housing 100 further includes an air suction passage 130, which is usually arranged at a rear side of the accommodating chamber 110, and the specific arrangement is determined according to actual needs. The air suction passage 130 forms a suction opening 131 at a rear side of an inner wall of the accommodating chamber 110, so that the air suction passage 130 is in communication with the accommodating chamber 110. In addition, the liquid waste tank 200 is provided with a first outlet 220 at a position away from the first inlet 210. When the liquid waste tank 200 is placed in the accommodating chamber 110, the position of the first outlet 220 is exactly the same as the position of the suction opening 131. Therefore, the first outlet 220 is in communication with the suction opening 131, and accordingly, the liquid waste tank 200 is in communication with the air suction passage 130.

[0098]In specific application, the air suction passage 130 is in communication with the external cleaning host 610 (not shown in the figures). When the cleaning host 610 is started, the cleaning host 610 exerts a suction force on the liquid waste tank 200 through the air suction passage 130, the inside of the liquid waste tank 200 is under a negative pressure, thus generating the suction force in the roller brush chamber 120. Therefore, when the brush head 300 rolls to brush the surface to be cleaned, the liquid waste enters the liquid waste tank 200 through the main inlet 121 and the first inlet 210 in sequence under the action of the suction force. Because the inner sidewall of the liquid waste tank 200 is provided with the retaining element 230, after the liquid waste is sucked into the liquid waste tank 200, it can be effectively retained in the liquid waste tank 200 under the restriction of the retaining element 230, which prevents the liquid waste from entering the cleaning host 610 along with the airflow, thereby ensuring the safety of using the cleaning host 610. Meanwhile, the retaining element 230 effectively prevents liquid waste from entering the air suction passage 130, which prevents the liquid waste from contaminating the air suction passage 130, thereby ensuring the cleanliness of the brush assembly 10 during use.

[0099]In other possible embodiments, instead of the air suction passage 130, a guide plate (not shown in the figures) is provided on the inner side of the roller brush chamber 120. One end of the guide plate is located on one side of the brush head 300, and the other end extends to the main inlet 121. In this way, the brush head 300 rotates to transfer the liquid waste to the guide plate, the liquid waste flows along the guide plate to the main inlet 121, and flows into the liquid waste tank 200 through the first inlet 210, to realize collection of the liquid waste.

[0100]In one possible embodiment, the liquid waste tank 200 is provided with the retaining element 230, which is the absorbent pad fitted on the inner wall of the liquid waste tank 200. The absorbent pad is made of superabsorbent polymers, a sponge or nylon It can be understood that the retaining element 230 employs the absorbent pad attached to the inner wall of the liquid waste tank 200, in this way, the retaining element 230 has a good retention effect on the liquid waste, thereby effectively preventing the liquid waste from overflowing from the first inlet 210 and the first outlet 220, and also effectively preventing the liquid waste from entering the air suction passage 130 along with the airflow.

[0101]Moreover, the retaining element 230 employs the absorbent pad, and the absorbent pad has a simple structure and can be arranged on the inner sidewall of the liquid waste tank 200 conveniently, which is conducive to mass production of the liquid waste tank 200.

[0102]In addition, the cost of the absorbent pad is low, and accordingly, the cost of the liquid waste tank 200 is also effectively reduced, and the liquid waste tank 200 can be used as a disposable consumable.

[0103]In other possible embodiments, the retaining element 230 is a baffle arranged in the liquid waste tank 200, where the baffle may be a structure integrally formed in the liquid waste tank 200, or a structure additionally arranged in the liquid waste tank 200, which is not specifically limited in this application. It can be understood that, with the arrangement of the baffle, after the liquid waste enters the liquid waste tank 200, the baffle serves to block the liquid waste entering the liquid waste tank 200, to retain the liquid waste in the liquid waste tank 200.

[0104]The present application also discloses the liquid waste tank 200, which is applied to the brush assembly 10, and the retaining element 230 is arranged inside the liquid waste tank 200. The liquid waste tank 200 is provided with the inlet and outlet (the first inlet 210 and the first outlet 220 mentioned above). When the liquid waste tank 200 is applied to the brush assembly 10, the wastewater enters the wastewater through the inlet and outlet.

[0105]It can be understood that a retaining element 230 is also provided in the liquid waste tank 200. The retaining element 230 at least partially restricts the movement of liquid waste from the inlet and outlet. More specifically, after the liquid waste enters the liquid waste tank 200 from the inlet and outlet, the retaining element 230 has a restricting effect on the liquid waste, thereby effectively restricting the movement of the liquid waste in the liquid waste tank 200, so that the liquid waste is kept in the liquid waste tank 200.

[0106]During the application, the retaining element 230 is provided inside the liquid waste tank 200, and the retaining element 230 can effectively restrict the movement of liquid waste in the liquid waste tank 200. In this way, even if the brush assembly 10 shakes during operation, with the retaining element 230, the liquid waste tank 200 can effectively prevent liquid waste from overflowing from the inlet and outlet, thereby ensuring that the brush assembly 10 can work effectively.

[0107]Moreover, during the use of the brush assembly 10, since the retaining element 230 can effectively prevent the liquid waste from overflowing from the inlet and outlet, the user does not need to frequently replace the liquid waste tank 200 or clean the liquid waste in the liquid waste tank 200 to prevent the liquid waste from overflowing when using the brush assembly 10, making it more convenient to use the brush assembly 10.

[0108]In addition, when the user needs to replace or clean the liquid waste tank 200, even if there is a large amount of liquid waste in the liquid waste tank 200, with the retaining element 230 being provided in the liquid waste tank 200, the movement of the liquid waste can be effectively restricted. Therefore, when the user disassembles and replaces the liquid waste tank 200, there is no need to worry that the wastewater in the liquid waste tank 200 will overflow from the inlet and outlet, thereby facilitating the replacement of the liquid waste tank 200.

[0109]The liquid waste tank 200 is a disposable consumable, more precisely, the liquid waste tank 200 is a disposable liquid waste tank 200, that is, a non-recyclable box. For example, each liquid waste tank 200 can be replaced by a new one after being used for one to three days, and accordingly, there is no need to reuse the liquid waste tank 200, which makes it more convenient to use the brush assembly 10.

[0110]In order to illustrate that the liquid waste tank 200 is a disposable consumable, in some embodiments, the liquid waste tank 200 is only provided with an inlet and outlet (the first inlet 210 and the first outlet 220 mentioned above). Specifically, the surface of the liquid waste tank 200 is only provided with an inlet and outlet, or the surface of the liquid waste tank 200 is only provided with an inlet and outlet, and accordingly, the liquid waste tank 200 is not provided with a replacement port 250 or other openings for other purposes, such as for replacing the absorbent pad.

[0111]Further, the liquid waste tank 200 is a closed box that cannot be dismantled. Specifically, the liquid waste tank 200 is a closed box, that is, the bottom, sides and top of the liquid waste tank 200 are all closed, that is, the liquid waste tank 200 is provided with no other openings except for the inlet and outlet. Also, the liquid waste tank 200 is a non-dismantle box, and the liquid waste tank 200 is an integral closed structure, rather than a box formed by connecting multiple shells. As can be seen from the above, in this application, the liquid waste tank 200 adopts the one-piece box, and the liquid waste tank 200 is a disposable consumable. The user cannot replace the absorbent pad in the liquid waste tank 200, which further clearly illustrates that the brush assembly 10 adopts a disposable liquid waste tank 200. Accordingly, there is no need to reuse the liquid waste tank 200, which makes it more convenient to use the brush assembly 10.

[0112]Illustrating from other angles that the liquid waste tank 200 is a disposable consumable, in some embodiments, the liquid waste tank 200 is a blow-molded box. It can be understood that the liquid waste tank 200 adopts a box formed by blow molding. In this way, the liquid waste tank 200 is a one-piece box, and the surface of the liquid waste tank 200 is only provided with the inlet and outlet. Accordingly, the liquid waste tank 200 cannot be provided with a replacement port 250 for replacing the absorbent pad. It can be seen that it is further clearly illustrated that the brush assembly 10 adopts a disposable liquid waste tank 200. Accordingly, there is no need to reuse the liquid waste tank 200, which makes it more convenient to use the brush assembly 10. Moreover, the liquid waste tank 200 is formed by blow molding, which makes it cost-effective and allows it to have a very thin thickness, making it suitable as a disposable consumable.

[0113]The present application also discloses a cleaning machine, including the above brush assembly 10.

[0114]In a possible embodiment, referring to FIGS. 2 to 4, the housing 100 is provided with an air suction passage 130, and the air suction passage 130 forms a suction opening 131 on the inner wall of the accommodating chamber 110; meanwhile, the surface of the liquid waste tank 200 is provided with a first outlet 220, and when the liquid waste tank 200 is placed in the accommodating chamber 110, the suction opening 131 is in communication with the first outlet 220. The brush assembly 10 also includes a connector 500, which is rotatably connected to the housing 100, and an inner end of the connector 500 is in communication with the air suction passage 130; the cleaning machine further includes an operating handle 600, on which a cleaning host 610 is provided, the operating handle 600 is connected to an outer end of the connector 500, and the cleaning host 610 is in communication with the connector 500 through a passage inside the operating handle 600.

[0115]In specific applications, the air suction passage 130 is in communication with the external cleaning host 610. When the cleaning host 610 is started, the cleaning host 610 exerts a suction force on the liquid waste tank 200 through the air suction passage 130, the inside wall of the liquid waste tank 200 is under a negative pressure, thus generating the suction force in the roller brush chamber 120. Therefore, when the brush head 300 rolls to brush the surface to be cleaned, the liquid waste enters the liquid waste tank 200 through the main inlet 121 and the first inlet 210 in sequence under the action of the suction force. Because the liquid waste tank 200 is provided with the retaining element 230 on the inner side, after the liquid waste is sucked into the liquid waste tank 200, it can be effectively retained in the liquid waste tank 200 under the restriction of the retaining element 230, which prevents the liquid waste from entering the cleaning host 610 along with the airflow, thereby ensuring the safety of using the cleaning host 610. Meanwhile, the retaining element 230 effectively prevents liquid waste from entering the air suction passage 130, which prevents the liquid waste from contaminating the air suction passage 130, thereby ensuring the cleanliness of the brush assembly 10 during use.

[0116]In other possible embodiments, instead of the cleaning host 610, a guide plate (not shown in the figures) is provided on the inner side of the roller brush chamber 120. One end of the guide plate is located on one side of the brush head 300, and the other end extends to the main inlet 121. In this way, the brush head 300 rotates to transfer the liquid waste to the guide plate, and the liquid waste flows along the guide plate to the main inlet 121 and flows into the liquid waste tank 200 through the first inlet 210, to realize collection of the liquid waste.
