[0060] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0061] Referring to Figures 1, 2, 3 and 4, a cleaning device provided in an embodiment of the present application includes a cleaning device 100 and a base station 200. The cleaning device 100 is used to perform the cleaning needs required by the user, such as sweeping or mopping the floor. Specifically, the cleaning device 100 includes a cleaning body 101 and a cleaning member 102. The cleaning member 102 is arranged on the cleaning body 101. The cleaning body 101 can carry the cleaning member 102 to move on the ground, so as to realize the action of sweeping or mopping the ground through the cleaning member 102.

[0062] The cleaning member 102 may be a mop, a roller brush, or other component that can be used to clean the floor, and the cleaning device 100 also has a self-cleaning function to clean the cleaning member 102. Specifically, when the cleaning device 100 performs self-cleaning, the cleaning body 101 is configured to spray a cleaning liquid onto the cleaning member 102, so that after the cleaning member 102 cleans the floor for a period of time, the cleaning liquid cleans the cleaning member 102, so that the stains on the cleaning member 102 can be removed, so that the cleaning member 102 can continue to clean the floor. Furthermore, a dirt collecting tank 110 is also provided on the cleaning body 101, and the sewage generated by the cleaning device 100 during the self-cleaning process can enter the dirt collecting tank 110, so that the sewage generated by washing the cleaning member 102 is collected by the dirt collecting tank 110 to prevent the sewage from flowing into the floor.

[0063] The base station 200 is used to perform operations such as water replenishment, charging, and cleaning on the cleaning device 100. The cleaning device 100 can enter or leave the base station 200 along the first direction X. The base station 200 has a sewage chamber 201. The cleaning body 101 is provided with a drainage hole 111 that is connected to the sewage tank 110. The drainage hole 111 is arranged on the inner wall of the sewage tank 110, and the drainage hole 111 can be opened and closed in a controlled manner. In addition, when the cleaning device 100 is located at the base station 200, the drainage hole 111 can be opened, and the opened drainage hole 111 is connected to the sewage chamber 201. When the cleaning device 100 leaves the base station 200, the drainage hole 111 is closed to prevent the sewage from leaking from the sewage tank 110, causing the sewage to pollute the ground when the cleaning device 100 is cleaning the ground.

[0064] By setting a drainage hole 111 in the sewage collecting tank 110, the sewage in the sewage collecting tank 110 is directly discharged from the sewage collecting tank 110 through the drainage hole 111, thereby effectively improving the sewage discharge capacity of the sewage collecting tank 110. In this way, after the cleaning device 100 enters the base station 200, the cleaning body 101 is controlled to discharge a large amount of water into the sewage collecting tank 110, so that the sewage collecting tank 110 is flushed with a large amount of water, thereby achieving the effect of cleaning the sewage collecting tank 110, thereby reducing the number of times and time for users to clean the sewage collecting tank 110.

[0065] Moreover, a large amount of water can be directly discharged into the sewage chamber 201 through the sewage discharge hole 111, that is, discharged into the base station 200, which is not only convenient for centralized treatment in the base station 200, but also can avoid a large amount of water accumulating in the sewage tank 110, causing sewage overflow and polluting the surrounding environment.

[0066] It should be noted that when it is necessary to control the cleaning body 101 to discharge a large amount of water into the sewage collecting tank 110, a large amount of water can be discharged through the water outlet structure used by the cleaning body 101 to clean the cleaning member 102. Although the discharged water will pass through the cleaning member 102, it will eventually enter the sewage collecting tank 110, thereby playing the role of cleaning the sewage collecting tank 110. In some other embodiments, the method of discharging a large amount of water into the sewage collecting tank 110 can also be achieved by separately setting a water outlet structure.

[0067] In some embodiments of the present application, referring to FIG. 5 and FIG. 6 , in order to realize the opening and closing of the drain hole 111, the cleaning device 100 includes a blocking cover 140, and the blocking cover 140 is movably mounted on the cleaning body 101. Further, referring to FIG. 10 and FIG. 11 , the blocking cover 140 includes a first position and a second position during the movement. When the blocking cover 140 is located at the first position, the blocking cover 140 opens the drain hole 111, and when the blocking cover 140 is located at the second position, the blocking cover 140 closes the drain hole 111, so that the opening and closing of the drain hole 111 is controlled by controlling the movement of the blocking cover 140.

[0068] Furthermore, a pusher 210 is provided on the base station 200, and the pusher 210 is used to drive the blocking cover 140 to move from the second position to the first position. In this way, only when the cleaning device 100 is located at the base station 200, the pusher 210 can push the blocking cover 140 to open the drainage hole 111, ensuring that when the drainage hole 111 is opened, the sewage discharged from the drainage hole 111 can be accurately input into the sewage chamber 201. In addition, by arranging the pusher 210 on the base station 200, the overall volume of the cleaning device 100 can be effectively reduced, which is convenient for improving the cleaning effect of the cleaning device 100.

[0069] It is understandable that in some other embodiments, the opening and closing of the drain hole 111 can also be achieved by a solenoid valve or the like, which is not limited here. The movement of the blocking cover 140 from the first position to the second position can be completed by the deadweight of the blocking cover 140, or can continue to be driven by the pusher 210, but the need to additionally set up a separation structure of the pusher 210 and the blocking cover 140 will further increase the separation structure of the pusher 210 and the blocking cover 140, which will increase additional costs or user workload.

[0070] To this end, in some embodiments, referring to FIG. 7 and FIG. 8 , the base station 200 further includes an elastic member 141, which is disposed between the stop cover 140 and the cleaning body 101, and when the stop cover 140 moves from the second position to the first position, the elastic member 141 accumulates an elastic force for driving the stop cover 140 to move from the first position to the second position. In this way, when the cleaning device 100 leaves the base station 200, the push member 210 separates from the stop cover 140, and the elastic member 141 will restore the elastic deformation, thereby pushing the stop cover 140 to move from the first position to the second position, and then closing the sewage outlet, so that the cleaning device 100 leaves the base station 200, and the sewage outlet is automatically closed to prevent sewage leakage.

[0071] Specifically in some embodiments, referring to FIG. 10 and FIG. 11 , the blocking cover 140 has a swinging section 142 and a blocking section 143 which are sequentially arranged, and the blocking cover 140 is rotatably mounted on the cleaning body 101 around a rotation axis, and the rotation axis is located between the swinging section 142 and the blocking section 143, and intersects with the first direction X. When the blocking cover 140 is located at the second position, the swinging section 142 is spaced apart from the cleaning body 101, and the blocking section 143 blocks the drain hole 111. Optionally, a rotating shaft 144 which can rotate around the rotation axis is provided on the cleaning body 101, and the blocking cover 140 is provided on the rotating shaft 144.

[0072] Among them, when the cleaning device 100 is located at the base station 200, the pushing member 210 is used to drive the swing section 142 to approach the cleaning body 101, and when the swing section 142 approaches the cleaning body 101, the blocking section 143 will move away from the cleaning body 101, so that the blocking section 143 can no longer continue to block the drain hole 111, the drain hole 111 is opened, and the blocking cover 140 moves to the position.

[0073] Furthermore, the elastic member 141 is disposed between the swing section 142 and the cleaning body 101. When the push member 210 drives the swing section 142 to approach the cleaning body 101, the swing section 142 will compress the elastic member 141. Afterwards, when the cleaning device 100 leaves the base station 200 and the push member 210 separates from the swing section 142, the elastic member 141 will restore its deformation, thereby pushing the swing section 142 away from the cleaning body 101, and finally making the blocking section 143 approach the cleaning body 101 until the blocking section 143 blocks the drain hole 111, and the blocking cover 140 moves to the second position.

[0074] It should be noted that in some other embodiments, the blocking cover 140 can also be moved horizontally. The pusher 210 drives the blocking cover 140 to move horizontally through magnetic attraction, and cooperates with the elastic member 141 to realize the movement of the blocking cover 140 between the first position and the second position.

[0075] Specifically, in some embodiments, the pusher 210 can move on the base station 200 along a second direction Y intersecting with the first direction X. When the cleaning device 100 is located at the base station 200, the pusher 210 can push the blocking cover 140 to move to the first position during the movement. That is, the blocking cover 140 is driven to move by the movable pusher 210, so that the blocking cover 140 can open the drain hole 111.

[0076] In other embodiments, a fixed pushing member 210 may be used, and the cleaning body 101 may move into the base station 200 so that the blocking rod 140 abuts against the pushing member 210 during the movement of the cleaning body 101, thereby allowing the pushing member 210 to push the blocking cover 140 to open the drain hole 111.

[0077] Specifically, in the embodiment of FIG. 4 , the first direction X is the left-right direction, and the second direction Y is the vertical direction. Furthermore, when the cleaning device 100 is located at the base station 200, the pusher 210 is located below the swing section 142 of the blocking cover 140, and the pusher 210 is movable in the vertical direction. Therefore, when the pusher 210 moves upward, the pusher 210 abuts against the swing section 142, and drives the swing section 142 to approach the cleaning body 130, so that the blocking section 143 is separated from the cleaning body 130, thereby opening the sewage discharge hole 111.

[0078] When the push member 210 moves downward, the push member 210 is separated from the first swing section 142 . Under the action of the elastic member 141 , the swing section 142 moves away from the cleaning body 130 , so that the blocking section 143 blocks the drain hole 111 .

[0079] In some embodiments, in order to reduce the impact of the pusher 210 in contact with the blocking cover 140 during the activity, the base station 200 further includes a shock absorber 211, and the shock absorber 211 can be deformed along a second direction Y intersecting both the first direction X and the direction of the rotation axis. When the cleaning device 100 is located at the base station 200, the shock absorber 211 is located between the pusher 210 and the blocking cover 140. The pusher 210 can drive the shock absorber 211 to deform during the movement, and make the shock absorber 211 and the blocking cover 140 abut against each other, that is, the pusher 210 does not directly contact the blocking cover 140, but indirectly contacts the blocking cover 140 through the shock absorber 211, thereby reducing the impact on the blocking cover 140 through the flexible shock absorber 211, thereby increasing the service life of the blocking cover 140.

[0080] In some embodiments of the present application, referring to FIG. 5, FIG. 12 and FIG. 13, the base station 200 includes a base structure 240, a driving member 241 and a transmission member 243, both of which are arranged on the base structure 240, and the pusher 210 is movably installed on the base structure 240 along the second direction Y, and the driving member 241 drives the pusher 210 to move through the transmission member 243. The driving member 241 can be a motor, and the transmission member 243 includes but is not limited to a worm gear, a gear rack 212, and the like.

[0081] In some embodiments, the transmission member 243 is a gear, which is in transmission connection with the driving member 241, and the pushing member 210 is provided with a rack 212 extending longitudinally along the second direction Y, and the rack 212 is meshed with the gear. When the driving member 241 drives the gear to rotate, the gear drives the rack 212 to move, so that the pushing member 210 moves along the second direction Y, thereby pushing the blocking cover 140 to move.

[0082] Specifically in some embodiments, the pushing member 210 includes an extended position and a retracted position during the activity. When the cleaning device 100 is located at the base station 200 and the pushing member 210 is in the extended position, the blocking cover 140 is in the first position. When the pushing member 210 is in the retracted position, the pushing member 210 avoids the movement path of the cleaning device 100 leaving or entering the base station 200.

[0083] Furthermore, the base station 200 also includes an in-place detection component 244 disposed on the base structure 240, and the in-place detection component 244 is used to detect the position of the pushing member 210, and when the pushing member 210 is in the extended position, the in-place detection component 244 outputs a first signal, and when the pushing member 210 is in the retracted position, the in-place detection component 244 outputs a second signal, and the driving member 241 stops driving the pushing member 210 to move according to the first signal or the second signal, so that the pushing member 210 stops at the first position or the second position.

[0084] Specifically, the driving member 241 is a motor, and when the cleaning device 100 enters the base station 200, the motor starts to operate after receiving a signal that the cleaning device 100 has moved into position, and the driving gear rotates forward through the rack 212 to drive the pusher 210 to move upward, so as to push open the blocking cover 140 and open the drainage hole 111. In addition, when the pusher 210 moves to the extended position, the in-position detection component 244 detects that the pusher 210 is in the extended position and sends a first signal. The driving member 241 stops driving the pusher 210 according to the first signal, so that the pusher 210 stops in the extended position, thereby maintaining the state in which the blocking cover 140 opens the drainage hole 111.

[0085] When the cleaning device 100 needs to leave the base station 200, the motor receives the corresponding signal and drives the gear to reverse to drive the pusher 210 to move downward through the rack 212 to leave the blocking cover 140, so that the blocking cover 140 can close the drain hole 111 under the action of the elastic member 141. In addition, when the blocking cover moves to the retracted position, the in-position detection component 244 detects that the pusher is in the retracted position and sends a second signal. The driving member 241 stops driving the pusher 210 according to the second signal, so that the pusher 210 stops at the retracted position to prevent the pusher 210 from affecting the movement of the cleaning device leaving the base station 200.

[0086] Specifically in some embodiments, the in-position detection component 244 includes a first optical coupler switch 245 and a second optical coupler switch 246, and the first optical coupler switch 245 and the second optical coupler switch 246 are arranged at intervals along the second direction Y. When the pusher 210 is in the extended position, the pusher 210 avoids the second optical coupler switch 246 and is partially located in the first optical coupler switch 245, so that the first optical coupler switch 245 is triggered, thereby sending a signal that the pusher 210 has moved to the position to the processing device of the base station 200, and the processing device then sends a stop signal to the driving member 241, thereby stopping the driving member 241 from continuing to move, so that the pusher 210 remains in the extended position, and the sewage discharge hole 111 can continue to open until the sewage discharge is completed and the cleaning device 100 needs to leave the base station 200.

[0087] When the pusher 210 is in the retracted position, the pusher 210 is hidden from the first photocoupler switch 245 and partially located in the second photocoupler switch 246. The second photocoupler switch 246 is triggered, thereby sending a signal to the processing device of the base station 200 that the pusher 210 has moved to the position, and the processing device then sends a stop signal to the driving member 241, thereby stopping the driving member 241 from continuing to move, so that the pusher 210 remains in the retracted position, and the pusher 210 is prevented from affecting the movement of the cleaning device 100.

[0088] In some embodiments, a limiting groove 248 extending longitudinally in the second direction Y is provided on one of the base structure 240 and the pushing member 210, and a limiting rib 247 is provided on the other. The limiting rib 247 is disposed in the limiting groove 248, so that the pushing member 210 can stably move along the second direction Y through the cooperation between the limiting rib 247 and the limiting groove 248, thereby ensuring that the pushing member 210 can accurately push the blocking cover 140 to move.

[0089] In some embodiments, referring to FIG. 9 and FIG. 10 , the cleaning body 101 further includes a sealing member 112. When the blocking cover 140 closes the drain hole 111, the sealing member 112 is sealed between the cleaning body 101 and the blocking cover 140, so that the drain hole 111 is sealed by the sealing member 112 to prevent sewage from leaking from the gap between the drain hole 111 and the blocking cover 140. Specifically, part of the sealing member 112 is disposed in the drain hole 111, and the other part extends out from the drain hole 111, so that when the blocking cover 140 is located in the second position, the blocking cover 140 can abut against the portion of the sealing member 112 that extends out, so that the sealing member 112 seals the gap between the cleaning body 101 and the blocking cover 140.

[0090] In some embodiments, in order to make the sewage in the sewage tank 110 flow out of the drainage hole 111 as much as possible, when the cleaning device 100 is located at the base station 200, the bottom wall of the sewage tank 110 is tilted relative to the horizontal direction. By tilting the bottom wall, the sewage in the sewage tank 110 will flow to the lowest point of the bottom wall under the action of gravity. The drainage hole 111 is located at the lowest point of the bottom wall of the sewage tank 110 in the gravity direction, so that the sewage in the sewage tank 110 is guided to the drainage hole 111 under the action of the bottom wall of the sewage tank 110, and finally flows out from the drainage hole 111.

[0091] Specifically, referring to FIG. 7, FIG. 8 and FIG. 9, the cleaning body 101 further includes a filter 113, which is disposed in the sewage collecting tank 110 and is located at the lowest point of the bottom wall in the gravity direction. The drainage hole 111 is located in the filter 113, and the sewage in the sewage collecting tank 110 enters the drainage hole 111 through the filter 113. In this way, the larger debris in the sewage collecting tank 110 is filtered by the filter 113 to prevent the debris from clogging the drainage hole 111, and at the same time, the debris can be left in the sewage collecting tank 110, and the user can clean up the debris together when cleaning the sewage collecting tank 110.

[0092] The sewage collecting tank 110 has two opposite side walls, each of which is formed with a fixing groove 115, and opposite ends of the filter element 113 are inserted into the two fixing grooves 115, so that the filter element 113 is fixed in the fixing groove 115 through the two fixing grooves 115. Specifically, the sewage collecting tank 110 has a first side wall and a second side wall opposite to each other in the direction of the rotation axis, and two fixing columns 116 are arranged at intervals along the first direction X on the first side wall and the second side wall, and each fixing column 116 extends longitudinally along the second direction Y, and one end of the filter element 113 in the direction of the rotation axis is inserted between the two fixing columns 116 of the first side wall, and the other end is inserted between the two fixing columns 116 on the second side wall, so that the filter element 113 is fixed in the fixing groove 115.

[0093] Specifically, in FIG. 10 , the first direction X is the left-right direction, the second direction Y is the vertical direction, and the direction of the rotation axis is perpendicular to the paper surface.

[0094] Since the sewage enters the sewage collecting tank 110 from the opening 203 of the sewage collecting tank 110, in some other embodiments, the filter 113 may be arranged in the sewage collecting tank 110, and the filter 113 covers the top opening 203 of the sewage collecting tank, and the drainage hole 111 is located on the bottom wall of the sewage collecting tank 110. In this way, after the sewage enters from the opening 203 of the sewage collecting tank 110, it will first be filtered by the filter 113, and then the debris will remain on the filter 113. After passing through the filter 113, the sewage enters the sewage collecting tank 110 and is finally discharged through the drainage hole 111.

[0095] In some embodiments of the present application, referring to FIG. 3 , the cleaning device 100 includes a cleaning bracket 160, a waterway plate 161 and a dirt scraping plate 162. The dirt scraping plate 162 and the dirt collecting tank 110 are both arranged on the cleaning bracket 160. When the cleaning device 100 is in use, the waterway plate 161, the dirt scraping plate 162 and the dirt collecting tank 110 are arranged in sequence along the gravity direction. When the cleaning member 102 is rotatable around its own axis, the waterway plate 161 is used to spray the cleaning liquid onto the circumferential side wall of the cleaning member 102, and the dirt scraping plate 162 is in contact with the circumferential side wall of the cleaning member 102.

[0096] Among them, the cleaning member 102 is a roller, and a mop is arranged on the surface of the roller. The waterway plate 161 can spray cleaning liquid toward the surface of the roller, and then the roller rotates. During the rotation, the surface of the roller is constantly in contact with the scraper plate 162, and the scraper plate 162 rubs the mop on the surface of the roller, and cooperates with the cleaning liquid to wash away the stains on the mop, and then the sewage formed falls into the sewage tank 110 in the sewage tank 110.

[0097] Furthermore, the cleaning body 101 includes a clean water tank and a dirty water tank. The clean water tank is used to store cleaning liquid, and is connected to the waterway plate 161, so that the cleaning liquid in the clean water tank is sprayed on the cleaning member 102 through the waterway plate 161 by gravity or a water pump. The dirty water tank is connected to the sewage tank 110, and the dirty water in the sewage tank 110 can be discharged into the dirty water tank, so that it is centrally stored in the dirty water tank, so that the user can clean it regularly.

[0098] Furthermore, in order to allow the sewage in the sewage collecting tank 110 to enter the sewage tank, the cleaning body 101 further includes a vacuum pump and a sewage discharge pipe 114. The vacuum pump is used to vacuum the sewage chamber 201 in the sewage tank, and the sewage tank extends into the filter element 113 of the filter tank through the sewage discharge pipe 114. In this way, under the action of the internal vacuum, the sewage in the sewage collecting tank 110 will be sucked into the sewage tank through the sewage discharge pipe 114. In some other embodiments, the sewage in the sewage collecting tank 110 can also be pumped into the sewage tank by means of a water pump.

[0099] In some embodiments of the present application, after the cleaning device 100 moves to the base station 200, the sewage trough 110 is above the sewage chamber 201 in the direction of gravity, so that the sewage in the sewage trough 110 can be discharged into the sewage chamber 201 through the sewage discharge hole 111 under the action of gravity.

[0100] Further, referring to Fig. 2 and Fig. 3, a sewage trough 202 is provided on the base structure 240 of the base station 200, a sewage cavity 201 is formed in the sewage trough 202, and a top opening 203 of the sewage trough 202 is connected to the sewage cavity 201. When the cleaning device 100 is located at the base station, the sewage discharge holes 111 are all located above the opening 203 of the sewage trough 202 in the direction of gravity, so that the sewage discharged from the sewage discharge holes 111 located at the bottom of the cleaning device 100 can all fall into the sewage cavity 201 through the opening 203 of the sewage trough 202.

[0101] In some other embodiments, the sewage hole 111 can also discharge the sewage into the sewage chamber 201 through a connecting hole or the like, that is, the sewage chamber 201 is arranged inside the base station 200. When the cleaning device 100 is located at the base station, the opened sewage hole 111 is connected to the connecting hole on the base station 200, thereby discharging the sewage into the sewage chamber 201.

[0102] In some embodiments of the present application, in order to centrally process the sewage collected multiple times, the base station 200 further includes a black water tank and a sewage pumping pipe 204. The black water tank is connected to the sewage tank 202 through the sewage pumping pipe 204, and the sewage in the sewage tank 202 can be pumped into the black water tank through the sewage pumping pipe 204. Each time the cleaning device 100 returns to the base station 200, the sewage will flow into the sewage tank 202 through the sewage hole 111, and finally be pumped into the black water tank for temporary storage so that the user can process it uniformly. Optionally, the base station 200 further includes a vacuum pumping member, which is used to vacuum the black water tank so that the sewage in the sewage tank 202 is pumped into the black water tank under the action of air pressure.

[0103] Furthermore, the base structure 240 further includes a plurality of filter ribs 205, all of which are protrudingly disposed on the bottom wall of the sewage tank 202 and are disposed at intervals around the sewage extraction pipe 204 in the circumferential direction, so that the sewage in the sewage tank 202 first passes through the plurality of filter ribs 205 and is then sucked into the black water tank by the sewage extraction pipe 204. In the process of the sewage passing through the plurality of filter ribs 205, the larger impurities in the sewage will be intercepted by the filter ribs 205, thereby preventing the impurities from entering the sewage extraction pipe 204 and clogging the sewage extraction pipe 204.

[0104] Specifically in some embodiments, referring to FIG. 4 , the base structure 240 includes a base body 250 and a sewage tray 251. The sewage tray 251 is detachably mounted on the base of the base station 200, and a sewage trough 202 is provided on the sewage tray 251, so that the user can remove the sewage tray 251 separately from the base body 250, thereby facilitating the cleaning of the sewage trough 202.

[0105] The base body 250 is also provided with the driving member 241, the transmission member 243, the pushing member 210 and the shock absorbing member 211. Meanwhile, the sewage tray 251 is provided with an avoidance hole 252. When the sewage tray 251 is mounted on the base body 250, the shock absorbing member 211 is located in the avoidance hole 252, or the avoidance hole 252 is located on the movement path of the shock absorbing member 211 driven by the pushing member 210. That is, the normal movement of the pushing member 210 and the shock absorbing member 211 is ensured by the avoidance hole 252.

[0106] Further, referring to Figure 14, the base body 250 also includes a base bracket 253 and a motor bracket 254. The motor bracket 254 is detachably arranged on the base bracket 253. The driving member 241, the transmission member 243, the pushing member 210, and the shock absorbing member 211 are all arranged on the motor bracket 254, so that the driving member 241, the transmission member 243, the pushing member 210, the shock absorbing member 211 and the motor bracket 254 form a driving module 260, and the driving module 260 can be easily repaired and replaced by the separately detachable driving module 260.

[0107] Furthermore, the base body 250 further includes a sealing cover 255, a mounting hole 256 is provided on the base bracket 253, the driving module 260 is installed in the mounting hole 256 by means of bolts, buckles, etc., and the sealing cover 255 is detachably provided on the mounting hole 256, so that when the driving module 260 is installed in the mounting hole 256, the sealing cover 255 prevents dust or debris from entering the mounting hole 256 and affecting the operation of the driving module 260. Among them, the inner wall of the mounting hole 256 also has a wiring hole, and the wires connected to the driving member 241 are connected to the control device of the base station 200 through the wiring hole.

[0108] In some embodiments of the present application, the cleaning device 100 is a sweeping robot, and the base station 200 also includes a charging device. After the sweeping robot enters the base station 200, the charging structure on the sweeping robot and the charging device on the base station 200 are connected to each other, thereby forming a charging circuit to start charging, and the sweeping robot can also determine that it has been docked on the base station 200 through the connection of the charging circuit, thereby stopping moving. In some other embodiments, the cleaning device 100 can also be a cleaning device 100 with a self-cleaning function such as a floor scrubber.

[0109] The cleaning device 100 has at least the following advantages:

[0110] By setting a drain hole 111 in the sewage collecting tank 110, the sewage in the sewage collecting tank 110 can not only be discharged into the sewage cavity 201, but also can be directly discharged from the sewage collecting tank 110 through the drain hole 111, thereby effectively improving the sewage discharge capacity of the sewage collecting tank 110. In this way, after the cleaning device 100 enters the base station 200, the cleaning body 101 is controlled to discharge a large amount of water into the sewage collecting tank 110, so that the sewage collecting tank 110 is flushed with a large amount of water to achieve the effect of cleaning the sewage collecting tank 110. In addition, a large amount of water can be directly discharged into the sewage cavity 201 through the drain hole 111, that is, discharged into the base station 200, which is not only convenient for centralized treatment in the base station 200, but also can avoid a large amount of water accumulating in the sewage collecting tank 110, causing sewage to overflow and pollute the surrounding environment.

[0111] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0112] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
