[0053] With the development of science and technology and the improvement of living standards, household cleaning equipment has become more and more popular, reducing the burden of human housework. Household cleaning equipment includes sweeping robots, floor washing robots, and sweeping and mopping robots. In the related technology, taking a floor washing machine as an example, in the related technology, the floor washing machine includes a main unit and a floor brush assembly rotatably connected to the main unit. The main unit can rotate between a lying posture and an upright posture relative to the floor brush assembly. The main unit has a negative pressure device and a sewage tank. The floor brush assembly is used to wet mop the surface to be cleaned (such as the ground). The negative pressure device is used to provide adsorption wind force to suck the sewage generated by the floor brush assembly during the cleaning process into the sewage tank. The sewage in the sewage tank needs to be dumped in time, otherwise it is easy to stink. Therefore, the sewage tank is usually detachably connected to the main unit to facilitate manual cleaning of the sewage in the sewage tank.

[0054] However, when cleaning the sewage tank manually, the sewage tank inside the sewage tank needs to be cleaned manually, and hands, clothes, etc. are easily dirty during cleaning, resulting in a poor user experience.

[0055] In order to solve the above problems, an embodiment of the present application provides a base station and a cleaning system. The base station is provided with an automatic disassembly and assembly mechanism on the base station body. The automatic disassembly and assembly mechanism includes a driving assembly and a force-applying member. One end of the force-applying member is connected to the driving assembly so that the driving assembly drives the force-applying member to rotate around its own axis. The force-applying member is constructed to apply a torsional force to the drain cover so that the drain cover in the sewage tank is separated from the drain outlet, so that the sewage in the sewage tank can be discharged through the drain outlet, thereby achieving the purpose of automatically cleaning the sewage in the sewage tank. There is no need to manually clean the sewage in the sewage tank, which reduces the burden of manual cleaning and improves the user experience.

[0056] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0057] Please refer to Figures 1 to 10 As shown, the base station 200 provided in the embodiment of the present application is suitable for docking a cleaning device, which may be a wet and dry cleaning robot. For example, the cleaning device may be a mopping robot, or a sweeping and mopping robot, or a floor scrubber, etc. The following will take the floor scrubber as an example for introduction.

[0058] In some embodiments, Figures 1 to 4As shown, the cleaning device includes a sewage tank 100, which includes a box body 110, and the box body 110 has a accommodating chamber 111 and a sewage inlet 112. The sewage inlet 112 is connected to the accommodating chamber 111, so that sewage generated when washing or mopping the floor, for example, is collected in the accommodating chamber 111 through the sewage inlet 112.

[0059] Exemplarily, the sewage inlet 112 may be disposed at a position close to the top of the housing 110 , so that the volume of the housing 110 may be increased and the problem of sewage leaking out through the sewage inlet 112 may be avoided.

[0060] In some embodiments, the box body 110 also includes a sewage discharge portion 120, which has a sewage discharge channel 121. One end of the sewage discharge channel 121 passes through the bottom of the box body 110 and is connected to the accommodating chamber 111. The other end of the sewage discharge channel 121 has a sewage discharge port 122. In this way, the sewage in the box body 110 can be discharged from the sewage discharge port 122 through the sewage discharge channel 121.

[0061] It should be noted that one end of the sewage discharge channel 121 passes through the bottom of the box body 110, which means passing through the bottom wall of the box body 110 or the side wall close to the bottom wall, etc., as long as it is convenient for the sewage in the box body 110 to be discharged through the sewage discharge channel 121 and avoids the presence of sewage residue in the box body 110 when it is discharged.

[0062] In some embodiments, the sewage tank 100 also includes a drain cover 130, which is openably and closably arranged at the drain outlet 122. Exemplarily, when the sewage tank 100 is installed on the cleaning equipment and cleans the floor, the drain cover 130 is in a closed state to prevent the sewage in the box body 110 from flowing out through the drain outlet 122; and when the cleaning equipment is docked at the base station 200 matched with it, the base station 200 includes an automatic disassembly and assembly mechanism, and the automatic disassembly and assembly mechanism includes a force-applying member 240, and the force-applying member 240 is constructed to apply a force to the drain cover 130 so that the drain cover 130 is separated from the drain outlet 122 under the force of the force-applying member 240, and the drain outlet 122 is in an open state, so that the sewage in the sewage tank 100 can be discharged into the box body 110 through the drain outlet 122, thereby achieving the purpose of automatically cleaning the sewage in the sewage tank 100, and there is no need to manually clean the sewage tank 100.

[0063] It can be understood that when the cleaning equipment is docked at the base station 200, the sewage outlet 122 of the sewage tank 100 is connected to one end of the water receiving pipe 250 in the base station 200, and the other end of the water receiving pipe 250 is connected to the sewage of the base station 200, and the sewage pipe 260 is connected to, for example, the sewage floor drain of the user's home. In this way, when the cleaning equipment is docked at the base station 200, the sewage outlet 122 can be automatically opened under the action of the automatic disassembly and assembly mechanism, without the need for manual dumping, thereby reducing the manual cleaning burden and improving the user experience.

[0064] In some embodiments, a force-bearing portion 131 may be provided on the outer wall of the sewage cover 130, and the force-bearing portion 131 is constructed to allow external force to be applied thereto. For example, the force-bearing portion 131 is constructed to allow the force-applying member 240 in the base station 200 to apply force thereto so that the sewage cover 130 is detached from or covers the sewage outlet 122.

[0065] It is understandable that by providing a force-bearing portion 131 on the outer wall of the drain cover 130, the force applied to the drain cover 130 by the force-applying member 240 is concentrated on the force-bearing portion 131 to reduce the waste of force, so that the drain cover 130 can be driven away from the drain outlet 122 with a smaller force.

[0066] In addition, when the sewage in the sewage tank 100 is cleaned, for example, the automatic disassembly and assembly mechanism in the base station 200 can drive the sewage cover 130 to cover the sewage outlet 122, and apply a force to the force-bearing part 131 of the sewage cover 130 through the force-applying member 240, so that the sewage cover 130 is installed at the sewage outlet 122.

[0067] Alternatively, when the drain cover 130 needs to be removed from the drain outlet 122 , a force may be manually applied to the force-bearing portion 131 of the drain cover 130 by a force-applying tool, so that the drain cover 130 is detached from the drain outlet 122 .

[0068] In some embodiments, the drain cover 130 is, for example, screwed on the drain outlet 122; or, the drain cover 130 can be sealed on the drain outlet 122 by a snap-on method, for example, the drain cover 130 has a snap button (not shown in the figure), and the wall surface of the drain outlet 122 has a first snap-on groove (not shown in the figure) extending along the extension direction of the drain outlet 122, and a second snap-on groove (not shown in the figure) connected to the first snap-on groove and extending along the circumference of the drain outlet 122. In this way, when the drain cover 130 is in contact with the drain outlet 122, When connected at the drain outlet 122, the buckle on the drain cover 130 can be inserted through the first slot and moved to a position connected to the second slot, and the drain cover 130 is rotated so that the buckle is located in the second slot, so that the drain cover 130 is snapped into the drain outlet 122; and when the drain cover 130 needs to be removed, the drain cover 130 can be rotated in the opposite direction so that the buckle rotates to the first slot and the drain cover 130 moves to the end away from the drain outlet, so that the drain cover 130 is detached from the drain outlet.

[0069] In some embodiments, a rotational torque can be applied to the drain cover 130 through, for example, an automatic disassembly and assembly mechanism or other force-applying tools in the base station, so that the drain cover 130 can fall off from the drain outlet 122, or an opposite rotational torque can be applied to the drain cover 130 through an automatic disassembly and assembly mechanism or a force-applying tool, so that the drain cover 130 can be turned at the drain outlet 122, thereby achieving the purpose of closing or opening the drain outlet 122.

[0070] For example, in Figure 3 and Figure 4 In the embodiment, the drain cover 130 has an internal thread 132 , and the outer wall surface of the drain part 120 near the drain port 122 has an external thread 123 matching the internal thread 132 . The drain cover 130 is screwed together with the external thread 123 on the drain part 120 through the internal thread 132 .

[0071] In a specific implementation, when the automatic disassembly and assembly mechanism on the base station 200 or a manual force-applying tool applies a rotational torque to the force-bearing portion 131 on the drain cover 130 , the drain cover 130 performs a spiral motion with the drain portion 120 so that the drain cover 130 is detached from the drain outlet 122 .

[0072] In some embodiments, the force-bearing portion 131 includes a protrusion disposed on the outer wall of the drain cover 130 , so that the automatic disassembly and assembly mechanism or the force-applying tool can apply a force to the drain cover 130 .

[0073] Exemplarily, a plurality of protrusions may be disposed on the outer wall of the sewage cover 130 , and the plurality of protrusions are spaced apart along the circumference of the sewage cover 130 , so that the plurality of protrusions together form the force-bearing portion 131 .

[0074] The protrusions on the outer wall of the drain cover 130 are, for example, structures such as protruding ribs, as long as it is convenient for an automatic disassembly and assembly mechanism to apply a force to the drain cover 130 .

[0075] In some embodiments, the cross-sectional shape of the protrusion on the outer wall of the drain cover 130 is, for example, a rectangle, a square, a triangle, a trapezoid, etc., which is not specifically limited here.

[0076] Exemplarily, the force-applying member 240 in the automatic disassembly and assembly mechanism in the base station 200 is, for example, a spiral rod, one end of which has a groove 242 matching the outer contour of the drain cover 130, and the groove wall of the groove 242 has a force-applying portion 241 matching the protrusion, and the force-applying portion 241 is, for example, a depression matching the protrusion, and when the drain cover 130 is located in the groove 242, the protrusion is located in the depression. In this way, when the spiral rod is rotated, a knob force can be applied to the drain cover 130 through the spiral rod, so that the protrusion and the side walls of the depression push each other to cause the drain cover 130 to rotate around its own axis, so that the drain cover 130 is detached from the drain outlet 122; or, when the drain cover 130 needs to be screwed into the drain outlet 122, a reverse force can be applied to the drain cover 130 through the force-applying member 240 to cause the drain cover 130 to close the drain outlet 122.

[0077] Among them, when there are multiple protrusions on the sewage cover 130, correspondingly, there are also multiple recesses matching the protrusions distributed along the circumference of the groove wall of the groove 242. In this way, when the sewage cover 130 is located in the groove 242, one protrusion is correspondingly located in one recess, so as to improve the reliability of the spiral rod applying force to the sewage cover 130.

[0078] In order to prevent the drain cover 130 from falling out of the groove 242 of the spiral rod after it detaches from the drain outlet 122, in an embodiment of the present application, the partial gap between the outer wall surface of the drain cover 130 and the groove wall of the groove 242 is 0 or approximately 0, as long as the drain cover 130 can be prevented from falling out of the groove 242.

[0079] In some embodiments, along the discharge direction of the sewage channel 121, the outer wall surface of the sewage cover 130 is a conical surface, and the cross-sectional area of ​​the sewage cover 130 gradually decreases, that is, the cross-sectional area of ​​the sewage cover 130 at the end close to the spiral rod is smaller than the cross-sectional area of ​​the sewage cover 130 at the end close to the box body 110. In this way, when the sewage cover 130 enters the groove 242 of the spiral rod and as the sewage cover 130 detaches from the sewage outlet 122, the gap between the outer avoidance surface of the sewage cover 130 at the end close to the sewage tank 100 and the groove wall of the groove 242 decreases successively until the gap between the outer wall surface of the sewage cover 130 and the groove wall of the groove 242 is 0, so that a tight fit structure is formed between the sewage cover 130 and the spiral rod to avoid the problem of the sewage cover 130 falling out of the groove 242 of the spiral rod after detaching from the sewage outlet 122.

[0080] In order to avoid water leakage when the drain cover 130 is sealed at the drain outlet 122, in the embodiment of the present application, a seal 140 is provided between the drain cover 130 and the drain outlet 122. Exemplarily, a seal 140 is provided between the internal thread 132 of the drain cover 130 and the external thread 123 of the drain part 120. In this way, the sealing performance of the drain cover 130 when it is sealed at the drain outlet 122 can be improved, thereby avoiding water leakage of the drain part 120.

[0081] In some embodiments, the seal 140 is a sealing sheet, sealing ring, sealing gasket, sealing strip, etc. made of elastic materials such as rubber and plastic, as long as it can improve the sealing between the drain cover 130 and the drain outlet 122, and no specific limitation is made here.

[0082] In addition, in order to improve the smoothness of sewage discharge in the box body 110, in the embodiment of the present application, the sewage channel 121 includes a diversion section 1211 and a sewage discharge section 1212 which are connected in sequence, the diversion section 1211 passes through the bottom wall of the box body 110 and is connected to the accommodating chamber 111, and the sewage outlet 122 is arranged at the end of the sewage discharge section 1212 away from the diversion section 1211; on the one hand, by making the diversion section 1211 pass through the bottom wall of the box body 110 and be connected to the accommodating chamber 111, the sewage in the box body 110 can be completely discharged through the diversion section 1211, the problem of sewage residue in the box body 110 can be avoided, and the user experience is improved; on the other hand, by setting the diversion section 1211, the sewage can be diverted to the set position for discharge to match the position of the sewage pipe 260 in the base station 200.

[0083] In some embodiments, there is an inclined angle between the diversion section 1211 and the bottom wall of the box body 110. For example, the inclined angle between the diversion section 1211 and the bottom wall of the box body 110 is between 0° and 90°, so as to guide the sewage to a set position and then discharge it.

[0084] In some embodiments, the inclination angle between the guide section 1211 and the bottom wall of the box body 110 is between 30° and 60°; illustratively, the inclination angle between the guide section 1211 and the bottom wall of the box body 110 is between 30° and 45°, 46° and 50°, or 51° and 60°. For example, the inclination angle between the guide section 1211 and the bottom wall of the box body 110 is 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc. The specific adaptive design can be carried out according to actual needs and is not limited here.

[0085] Among them, by forming an inclined angle between the guide section 1211 and the bottom wall of the box body 110, it is possible to avoid sewage residue in the box and guide the discharge direction of the sewage so that the sewage outlet 122 corresponds to the position of the water receiving pipe 250 in the base station 200, that is, the sewage outlet 122 is guided to the position of the water receiving pipe 250 connected to it in the base station 200. In this way, the sewage discharged from the sewage channel can be discharged to, for example, the sewage floor drain of the user's home through the sewage pipe 260 in the base station 200.

[0086] In order to facilitate the automatic disassembly and assembly mechanism to apply force to the force-bearing portion 131 of the sewage cover 130, in the embodiment of the present application, the extension direction of the sewage section 1212 is the same as the extension direction of the plane where the bottom wall of the box body 110 is located. Figures 1 to 4In the figure, the plane where the bottom wall of the box body 110 is located extends in the horizontal direction, and the sewage discharge section 1212 also extends in the horizontal direction. In this way, the sewage discharge cover 130 is detachably located at one end of the sewage discharge outlet 122 of the sewage discharge section 1212, so that the automatic disassembly and assembly mechanism can apply force to the force-bearing part 131 on the sewage discharge cover 130, so that the sewage discharge cover 130 can be separated from the sewage discharge outlet 122, or sealed at the sewage discharge outlet 122.

[0087] In addition, the sewage tank 100 further includes a solid-liquid separation structure 150, which is disposed in the accommodating cavity 111 along the depth direction of the sewage tank 100 and is located between the sewage inlet 112 and the sewage discharge portion 120, and the solid-liquid separation structure 150 has a separation hole through which liquid can pass. Exemplarily, the contour shape of the separation hole is, for example, circular, elliptical, rectangular, square, and the like.

[0088] In a specific implementation, sewage enters the containing chamber 111 through the sewage inlet 112. When the sewage passes through the solid-liquid separation structure 150, the liquid enters the bottom of the containing chamber 111 through the separation hole, and the solid waste in the sewage is filtered on the solid-liquid separation structure 150 to achieve solid-liquid separation of the waste in the sewage, thereby preventing the solid waste from entering the sewage channel 121 and causing the sewage channel 121 to be blocked.

[0089] Among them, the solid-liquid separation structure 150 can be disc-shaped and arranged in the accommodating cavity 111 by means such as snap-on. In order to improve the solid-liquid separation efficiency of sewage, there are multiple separation holes in the solid-liquid separation structure 150, and the separation holes are spaced and evenly distributed on the solid-liquid separation structure 150.

[0090] In some embodiments, the sewage tank 100 further has a ventilation structure 113 , and the ventilation structure 113 is disposed at one end of the sewage tank 100 close to the top, so that the volume of the sewage tank 100 can be increased.

[0091] Exemplarily, the ventilation structure 113 is disposed on the top of the sewage tank 100 to allow air to communicate between the sewage tank 100 and the outside.

[0092] Please refer to Figures 5 to 10As shown, the base station 200 provided in the embodiment of the present application includes a base station body 210 and an automatic disassembly and assembly mechanism, which is arranged on the base station 200. The automatic disassembly and assembly mechanism includes a driving assembly 230 and a force-applying member 240. One end of the force-applying member 240 is connected to the driving assembly 230. The driving assembly 230 is configured to drive the force-applying member 240 to rotate around its own axis, so that the force-applying member 240 applies a force to the drain cover 130 during the rotation process, thereby causing the drain cover 130 to detach from the drain outlet 122, so as to achieve the purpose of automatically opening the drain outlet 122, so that the sewage in the sewage tank 100 is discharged through the drain outlet 122, and there is no need to manually clean the sewage in the sewage tank 100, thereby reducing the burden of manually cleaning the sewage tank 100 and improving the user experience.

[0093] Exemplarily, the drain cover 130 is threadedly engaged with the drain outlet 122 , so that a knob force is applied to the drain cover 130 through the force applying member 240 , so that the drain cover 130 is separated from the drain outlet 122 , thereby achieving the purpose of automatic sewage discharge.

[0094] In some embodiments, the force applying member 240 is, for example, a screw rod, and the driving assembly 230 drives the screw rod to rotate around its own axis. The end of the screw rod away from the driving assembly 230 is connected to the drain cover 130, so that the drain cover 130 rotates relative to the sewage tank 100 and disengages from the drain outlet 122.

[0095] When the sewage in the sewage tank 100 is drained, the force applying member 240 can drive the sewage cover 130 to move to the sewage outlet 122 and apply a reverse twisting force to the sewage cover 130 so that the sewage cover 130 is screwed into the sewage outlet 122 .

[0096] In some embodiments, the force-applying member 240 has a force-applying portion 241 at one end away from the driving assembly 230 , and the outer wall surface of the sewage cover 130 has a force-receiving portion 131 matching the force-applying portion 241 , and the force-applying portion 241 is configured to apply a torsional force to the force-receiving portion 131 .

[0097] In the embodiment of the present application, a force-applying portion 241 is provided on the force-applying member 240, and a force-receiving portion 131 matching the force-applying portion 241 is provided on the sewage cover 130. When the driving assembly 230 drives the force-applying member 240 to rotate around its own axis, the force-applying member 240 applies a force to the force-receiving portion 131 on the sewage cover 130 through the force-applying portion 241. In this way, the concentration of the force can be improved, and the sewage cover 130 can be driven to move relative to the sewage outlet 122 with a smaller force.

[0098] In some embodiments, the end of the force-applying member 240 away from the driving assembly 230 has a groove 242 that matches the outer contour of the drain cover 130, and the force-applying portion 241 is arranged on the groove wall of the groove 242; when the force-applying member 240 needs to drive the drain cover 130 to move relative to the drain port 122, the drain cover 130 is located in the groove 242 of the force-applying member 240, and the force-applying portion 241 is connected to the force-receiving portion 131 on the drain cover 130, so that when the driving assembly 2 When the force-applying member 240 is driven to rotate, the force-applying member 240 pushes the force-bearing portion 131 on the drain cover 130 through the force-applying portion 241 to apply a force to the force-bearing portion 131, so that the drain cover 130 rotates relative to the drain outlet 122, so that the drain cover 130 is separated from the drain outlet 122, and the sewage in the sewage tank 100 is discharged through the drain outlet 122, thereby achieving the purpose of automatic sewage discharge, and there is no need to manually clean the sewage in the sewage tank 100.

[0099] In order to improve the reliability of the force-applying member 240 driving the drain cover 130 to move, in the embodiment of the present application, there are at least two force-applying parts 241, and correspondingly, there are at least two force-bearing parts 131 on the drain cover 130 in the sewage tank 100. The force-applying parts 241 are distributed at intervals along the circumferential direction on the groove wall of the groove 242, and the force-bearing parts 131 are distributed at intervals along the circumferential direction on the outer wall surface of the drain cover 130, wherein one force-applying part 241 corresponds to one force-bearing part 131, so that a force is applied to the force-bearing parts 131 corresponding thereto by the multiple force-applying parts 241 respectively, so that the reliability of driving the drain cover 130 to move can be improved, and the problem of jamming caused by uneven force on the drain cover 130 in the circumferential direction can be avoided.

[0100] In some embodiments, the force-applying portion 241 is one of a depression and a protrusion, and the force-receiving portion 131 on the drain cover 130 is the other of the depression and the protrusion.

[0101] For example, in Figure 8 In the embodiment, the force-applying portion 241 is a protrusion, and the force-bearing portion 131 is a depression matching the protrusion, so that when the driving member drives the force-applying member 240 to rotate around its own axis, the side wall surface of the protrusion fits with the wall surface of the depression to apply a pushing force to the wall surface of the depression, so as to drive the drain cover 130 to move relative to the drain outlet 122, so that the drain cover 130 is separated from the drain outlet 122; or, the force-applying member 240 rotates in the opposite direction, so that the force-applying portion 241 applies a reverse force to the force-bearing portion 131, so that the drain cover 130 is rotated and sealed at the drain outlet 122.

[0102] In some embodiments, please refer to Figure 5 and Figure 6As shown, the drive assembly 230 includes a drive motor 231, and the output shaft 232 of the drive motor 231 is configured to be connected to the force-applying member 240; illustratively, the output shaft 232 of the drive motor 231 can be fixedly connected to the force-applying member 240 via a threaded connector, for example; or, the output shaft 232 of the drive motor 231 is snap-fitted to the force-applying member 240, etc., as long as the output shaft 232 of the drive motor 231 can synchronously drive the force-applying member 240 to rotate, no specific limitation is made here.

[0103] In some embodiments, please refer to Figure 5 and Figure 6 As shown, the driving assembly 230 also includes a telescopic structure 233, which is constructed to drive the force-applying member 240 to telescopically move between a first position and a second position along the extension direction of the force-applying member 240 through a driving motor 231; wherein the first position is located between the sewage outlet 122 and the second position.

[0104] It can be understood that the extending direction of the force applying member 240 refers to the length extending direction of the force applying member 240 . The length extending direction of the force applying member 240 is, for example, the same as the axial direction of the sewage cover 130 .

[0105] The first position is, for example, a position where the drain cover 130 is threadedly engaged with the drain outlet 122 ; and the second position refers to a position where the drain cover 130 is separated from the drain outlet 122 .

[0106] In some embodiments, the telescopic structure 233 includes a gear 2331 and a rack 2332. The rack 2332 extends along the length direction of the force-applying member 240 and is connected to the drive motor 231. The gear 2331 is meshed with the rack 2332. The gear 2331 rotates around its own axis to drive the rack 2332 to drive the drive motor 231 and the force-applying member 240 to telescopically move between the first position and the second position, so that the sewage cover 130 is disengaged from or screwed into the sewage outlet 122.

[0107] In some embodiments, the base station 200 also includes a water receiving pipe 250 and a sewage pipe 260. The first end and the second end of the water receiving pipe 250 are both open structures, and the caliber of the first end of the water receiving pipe 250 is larger than the caliber of the second end. The first end of the water receiving pipe 250 is connected to the sewage outlet 122 of the sewage tank 100, and the second end of the water receiving pipe 250 is connected to one end of the sewage pipe 260. The other end of the sewage pipe 260 is configured to be connected to the sewage floor drain.

[0108] Exemplarily, the water receiving pipe 250 may be formed into a shape such as a funnel, so that the first end of the water receiving pipe 250 has sufficient tolerance relative to the sewage outlet 122 to avoid leakage of sewage discharged from the sewage outlet 122.

[0109] In some embodiments, when the force-applying member 240 drives the drain cover 130 that is separated from the drain outlet 122 to move to the second position, the projections of the drain cover 130 and the first end of the water receiving pipe 250 in the direction perpendicular to the central axis of the drain cover 130 at least partially overlap; in this way, when the drain outlet 122 opens to discharge sewage into the water receiving pipe 250, the drain pipe 260 can enclose the sewage discharged from the drain outlet 122 to prevent the sewage from splashing to one side of the force-applying member 240, thereby improving the user experience.

[0110] For example, Figure 5 In the embodiment, the cleaning device is docked at the base station 200, and the force-applying member 240 in the automatic disassembly and assembly mechanism is connected to the sewage cover 130, that is, the sewage cover 130 is located in the groove 242 of the force-applying member 240, and the force-bearing portion 131 (protrusion) on the outer wall of the sewage cover 130 is located in the force-applying portion 241 (recess) in the groove 242 of the force-applying member 240. In this way, the driving motor 231 drives the force-applying member 240 to rotate through the output shaft 232, so that the force-applying member The force-applying member 240 applies a circumferential thrust to the force-bearing portion 131 of the sewage cover 130 through the force-applying portion 241, and the gear 2331 rotates to drive the rack 2332 to drive the force-applying member 240 to move to the second position away from the sewage tank 100 through the driving motor 231, so that the sewage cover 130 is separated from the sewage outlet 122 to open the sewage outlet 122, and the telescopic structure 233 drives the force-applying member 240 to move to the second position (such as Figure 6 ), at this time, the sewage cover 130 is located in the groove 242 of the force-applying member 240, and the sewage outlet 122 is connected to the water receiving pipe 250 in the base station 200, so that the sewage is discharged to, for example, a sewage floor drain through the sewage outlet 122, the water receiving pipe 250, and the sewage pipe 260 in sequence, thereby achieving the purpose of automatically cleaning the sewage tank 100, without the need for manual cleaning of the sewage tank 100, and improving the user experience.

[0111] When the sewage is cleaned, the telescopic structure 233 and the driving motor 231 move in the opposite direction, so that the force-applying member 240 moves toward one side of the sewage tank 100, and through the reverse rotation of the driving motor 231, the sewage cover 130 is screwed into the sewage outlet 122 to close the sewage outlet 122, thereby preventing the sewage from leaking when the cleaning equipment leaves the base station 200 to clean the ground.

[0112] An embodiment of the present application also provides a cleaning system, including a cleaning device and a base station 200 provided in the above embodiment; the cleaning device includes a sewage tank 100, the sewage tank 100 has a sewage outlet 122 and a sewage cover 130, the sewage cover 130 is openably and closably arranged at the sewage outlet 122, and the outer wall surface of the sewage cover 130 has a force-bearing portion 131; the base station 200 includes an automatic disassembly and assembly mechanism, the automatic disassembly and assembly mechanism includes a force-applying member 240, and the force-applying member 240 is configured to apply a force to the force-bearing portion 131 of the sewage cover 130 to make the sewage cover 130 detach from or cover the sewage outlet 122.

[0113] In some embodiments, one end of the force-applying member 240 has a groove 242 that matches the outer contour of the drain cover 130, the outer wall surface of the drain cover 130 is a conical surface, and the cross-sectional dimension of the end of the drain cover 130 facing the force-applying member 240 is smaller than the cross-sectional dimension of the end away from the force-applying member 240. When the drain cover 130 is located in the groove 242, the gap between the wall surface of the end of the drain cover 130 with a larger cross-sectional dimension and the groove wall of the groove 242 is zero (e.g., Fig.10 As shown in ), in this way, the problem of the drain port 122 falling out of the groove 242 after the drain cover 130 is separated from the drain port 122 can be avoided.
