[0063] The embodiments of the present disclosure will be described in detail below with reference to examples thereof as illustrated in the accompanying drawings, throughout which same or similar elements, or elements having same or similar functions, are denoted by same or similar reference numerals. The embodiments described below with reference to the accompanying drawings are illustrative only, and are intended to explain rather than limiting the present disclosure.

[0064] Various embodiments or examples for implementing different structures of the embodiments of the present disclosure are provided below. To simplify the present disclosure, components and settings in specific examples are described below. Of course, they are merely exemplary and are not intended to limit the present disclosure. Moreover, the present disclosure may repeat reference numbers and / or reference letters in different examples. Such repetition is for purposes of simplicity and clarity and is in itself indicative of a relationship among the various embodiments and / or settings discussed. In addition, the present disclosure provides examples of various specific processes and materials, but those skilled in the art may recognize application of other processes and / or use of other materials.

[0065] A cleaning base station 100 for a cleaning device according to embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0066] Dirt adhered to a mopping member 200 of the cleaning device during cleaning can be better cleaned through the cleaning base station 100. Therefore, it is possible to better ensure cleanliness of the mopping member 200 of the cleaning device, which facilitates improving a cleaning effect of the cleaning device. Meanwhile, it is possible to better save energy of a user to frequently clean the cleaning device, which facilitates improving user experience of the cleaning device. In a specific example, the cleaning device is a sweeping and mopping robot. After the sweeping and mopping robot has operated in a cleaning mode for a certain period of time or after a large amount of dirt is accumulated on the mopping member 200 of the sweeping and mopping robot, the sweeping and mopping robot may automatically move to the cleaning base station 100 and cooperate with the cleaning base station 100 to clean the mopping member 200 of the sweeping and mopping robot through the cleaning base station 100, such as to remove the dirt on the mopping member 200. After the mopping member 200 is cleaned, the sweeping and mopping robot may be separated from the cleaning base station 100 and continue with the cleaning operation.

[0067] As illustrated in FIGS. 1 to 25, the cleaning base station 100 for the cleaning device according to the embodiments of the present disclosure comprises a base 1, a washing member 2, and a filtering assembly. The base 1 has a washing tank 111. The washing member 2 is movably disposed in the washing tank 111. The filtering assembly is disposed in the washing tank. Thus, sewage in the washing tank 111 can be better filtered through the filtering assembly, and the sewage in the washing tank 111 can be better agitated to flow through a movement of the washing member 2. Therefore, flowing of the sewage into the filtering assembly can be speeded up. In addition, the flowing sewage may drive solid dirt adhered to an inner wall of the washing tank 111 to flow together. As a result, the solid dirt can flow into the filtering assembly with the sewage. That is, the solid dirt can be better prevented from accumulating on the inner wall of the washing tank 111 through rotation of the washing member 2 relative to the washing tank 111. For example, hair, sticky substances, etc., can be prevented from adhering to the wall of the washing tank 111. In this way, a washing effect of the washing member 2 on the washing tank 111 is improved, which is beneficial to improving the cleanliness of the washing tank 111. Therefore, during washing of the mopping member 200, it is possible to prevent the dirt from accumulating in the washing tank 111, which would otherwise lead to secondary pollution to the mopping member 200. In this way, it is beneficial to improving cleaning intensity of the cleaning base station 100 of the mopping member 200. In addition, large particles of dirt in the sewage can be blocked through the filtering assembly. That is, the separation of the sewage from the solid dirt can be realized, which is convenient for subsequent classification and treatment of different types of dirt.

[0068] In the cleaning base station 100 for the cleaning device according to the embodiments of the present disclosure, the sewage can be better separated from the solid dirt through the filtering assembly, which is convenient for classifying and treating the different types of dirt. Meanwhile, since the washing member 2 is movably disposed in the washing tank 111, the solid dirt can be better prevented from accumulating on the inner wall of the washing tank 111 through the operation of the washing member 2 to clean the washing tank 111. Therefore, the cleanliness in the washing tank 111 can be improved, which facilitates improving the cleaning intensity of the cleaning base station 100 of the mopping member 200.

[0069] According to some embodiments of the present disclosure, the filtering assembly has a filtering tank 13 in communication with the washing tank. The filtering tank 13 is formed with a filtering structure at a bottom wall of the filtering tank 13. That is, the dirt in the washing tank 111 may flow into the filtering tank 13 with the sewage, and therefore the sewage in the washing tank 111 can be prevented from overflowing the base 1, which would otherwise pollute an environment. Sewage collected in the filtering tank 13 may pass through the filtering structure, and therefore the solid dirt such as solid particles and hair carried in the sewage can be better blocked by the filtering structure. That is, the sewage can be better separated from the solid dirt by the filtering structure in the filtering tank 13, which is convenient for classifying and treating the different types of dirt. Therefore, a treatment effect of the cleaning base station 100 on the dirt in the washing tank 111 can be better improved. In addition, during discharging of the sewage, for example, when the filtering tank 13 is in communication with a sewage discharge passage for discharging the sewage through the filtering structure, the filtering structure may prevent the solid dirt in the filtering tank 13 from entering a sewage discharge tube channel and blocking the sewage discharge tube channel to ensure that the sewage discharge tube channel is unobstructed, and thus to ensure that the sewage can be discharged smoothly through the sewage discharge passage.

[0070] In a specific example, the base 1 comprises a base body 11 and a filtering component 12. The washing tank 111 is formed in the base body 11. The filtering component 12 is disposed in the base body 11, and a sewage buffer chamber 14 and the filtering tank 13 are defined between the filtering component 12 and the base body 11. At least part of the filtering component 12 is constructed as the bottom wall of the filtering tank 13. The suction nozzle 7 and the filtering component 12 are movable relative to each other. That is, the filtering structure is formed at the filtering component 12. After the dirt in the washing tank 111 enters the filtering tank 13, the sewage may flow downwards into the sewage buffer chamber 14 through the filtering component 12 for temporary storage, and the solid dirt in the dirt is blocked at the filtering component 12. In addition, the filtering structure may prevent the solid dirt such as the solid particles and the hair from entering the sewage buffer chamber 14, which would otherwise be difficult to clean or block the sewage discharge passage during their direct discharging into the sewage discharge passage. The solid dirt is accumulated in the filtering structure located at the sewage buffer chamber 14, which may reduce difficulty in cleaning the solid dirt on the filtering structure.

[0071] According to some embodiments of the present disclosure, the bottom wall of the filtering tank 13 is lower than a bottom wall of the washing tank 111. Thus, the sewage in the washing tank 111 can flow towards the filtering tank 13 under gravity, that is, it is ensured that the sewage in the washing tank 111 can flow smoothly into the filtering tank 13 while better avoiding sewage residue in the washing tank 111. It should be noted that when the bottom wall of the washing tank 111 is non-planar, for example, when the bottom wall of the washing tank 111 has a predetermined slope, the filtering tank 13 is disposed adjacent to a lowest position of the washing tank 111, and the bottom wall of the filtering tank 13 is lower than a lowest position of the bottom wall of the washing tank 111, to avoid the sewage residue in the washing tank 111.

[0072] According to some embodiments of the present disclosure, the base has two washing tanks 111 arranged in a left-right direction. The filtering tank 13 is located between the two washing tanks 111. Dirt in each of the two washing tanks 111 is adapted to flow into the filtering tank 13. That is, the filtering tank 13 can simultaneously receive the dirt in the two washing tanks 111. That is, the two washing tanks 111 can share one filtering tank 13. Therefore, the number of filtering tanks 13 can be reduced to save a mounting space occupied by the filtering tanks 13, which facilitates controlling an overall size of the cleaning base station 100. In addition, the two washing tanks 111 can respectively wash two mopping members 200 of the cleaning device, which facilitates improving cleaning efficiency of the cleaning base station 100 on the mopping members 200.

[0073] According to some embodiments of the present disclosure, during a movement of the washing member 2, dirt in the washing tank 111 is adapted to flow into the filtering tank 13 under agitation of the washing member 2. That is, the sewage in the washing tank 111 can be better agitated to flow through the movement of the washing member 2. Therefore, the flowing of the sewage into the filtering tank 13 can be speeded up. In addition, the flowing sewage may drive the solid dirt adhered to the inner wall of the washing tank 111 to flow together. As a result, the solid dirt can flow into the filtering tank 13 with the sewage. That is, the solid dirt can be better prevented from accumulating on the inner wall of the washing tank 111 through rotation of the washing member 2 relative to the washing tank 111. For example, the hair, the sticky substances, etc., can be prevented from adhering to the wall of the washing tank 111. In this way, the washing effect of the washing member 2 on the washing tank 111 is improved, which is beneficial to improving the cleanliness of the washing tank 111.

[0074] According to some embodiments of the present disclosure, the washing member 2 is rotatably disposed in the washing tank 111 and has a rotation axis extending in an up-down direction. Thus, it is possible to increase a region swept by the washing member 2 in a horizontal direction. Therefore, an agitation effect of the washing member 2 on the dirt in the washing tank 111 can be improved. In this way, it is beneficial to further speeding up the dirt in the washing tank 111 to flow into the filtering tank 13 and preventing the solid dirt from accumulating on the inner wall of the washing tank 111. Meanwhile, it is possible to increase an area of washing tank 111 that the washing member 2 cleans. In this way, it is beneficial to improving the washing effect of the washing member 2 on the washing tank 111. The washing member 2 is adapted to pass over the filtering tank 13 during rotation of the washing member 2. Thus, the dirt in the washing tank 111 can be pushed into the filtering tank 13 by a part of the washing member 2 passing over the filtering tank 13 to speed up the dirt in the washing tank 111 to flow into the filtering tank 13.

[0075] In a specific example, the washing tank 111 is substantially of a circular shape. Therefore, by extending the rotation axis of the washing member 2 in the up-down direction, the washing member 2 can form a circular cleaning region during the rotation of the washing member 2. Therefore, the washing member 2 may be elongated with a same length as a diameter of the washing tank 111, and may be elongated with a same length as a radius of the washing tank 111, and also may be in a sector shape with a same radius as the radius of the washing tank 111, etc. The washing member 2 can form a circular cleaning region during the rotation of the washing member 2 to ensure that the cleaning region can cover any part of the washing tank 111. Therefore, requirements for the shape and the size of the washing member 2 can be better reduced, which has a wide range of application.

[0076] According to some embodiments of the present disclosure, the washing member 2 is formed with a washing surface 2a at an upper surface of the washing member 2 and a sweeping surface 2b at a lower surface of the washing member 2. The washing surface 2a is configured to be in contact with the mopping member 200 of the cleaning device, and the sweeping surface 2b is in contact with a bottom surface of the washing tank 111.

[0077] It can be understood that the substances described herein comprise but are not limited to solid garbage, such as large particles of garbage such as peels, fruit shells, cigarette butts and / or paper scraps.

[0078] In this embodiment, the washing member 2 is movably disposed in the washing tank 111. On the one hand, the mopping member 200 of the cleaning device can be washed through the washing surface 2a to ensure cleanliness of the mopping member 200. In this way, a clean mopping member 200 can be provided for the cleaning device to clean ground next time, avoiding secondary pollution of the ground caused by incomplete cleaning of the mopping member 200. On the other hand, through the sweeping surface 2b, substances dropped in the washing tank 111 can be swept into the filtering tank 13 through a dust opening 125. In this way, the solid garbage can be cleaned and cannot be exposed to the washing tank 111 to cause odor. As a result, the user does not need to wash and sweep the washing tank 111 every time after the mopping member 200 is washed by the washing member 2, which can also avoid the secondary pollution of the mopping member 200 due to the solid garbage remaining in the washing tank 111. Thus, it is convenient for the user to clean, which has a good user experience.

[0079] According to some embodiments of the present disclosure, the washing member 2 comprises a fixing seat 26, a support body 27, and a support arm 28. The fixing seat 26 is fixedly disposed at the bottom surface of the washing tank 111. Exemplarily, the fixing seat 26 is formed with a first mounting hole 26a, and the washing tank 111 is formed with a second mounting hole 1a2 at the bottom surface of the washing tank 111. The fixing seat 26 may be fixed at the bottom surface of the washing tank 111 by fasteners such as screws or studs to pass through the first mounting hole 26a and the second mounting hole 1a2 to provide stable support.

[0080] The support body 27 is rotatably connected to the fixing seat 26. The support arm 28 is disposed at a circumferential surface of the support body 27. The washing surface 2a is formed at an upper surface of the support arm 28, and the sweeping surface 2b is formed at a lower surface of the support arm 28. In this way, the mopping member 200 and the substances at the washing tank 111 can be washed by rotating the support arm 28 at the support body 27, which is comprehensive in the cleaning to prevent the substances from being exposed to the washing tank 111. In this way, the user experience is improved.

[0081] According to some embodiments of the present disclosure, the washing member comprises a plurality of support arms 28 arranged at intervals in an axial direction of the support body 27. Exemplarily, a shape of the support body 27 is not limited, for example, the support body 27 may be cylindrical, conical, frustum-shaped, spherical or other shapes. The number of support arms 28 is not limited, for example, it may be 2, 3, 4, or more than 4. Three support arms 28 will be described as an example. The three support arms 28 are circumferentially arranged at intervals of 120° at the support body 27. In this way, the washing tank 111 can be repeatedly washed and swept at a same rotational speed to ensure that the substances in the washing tank 111 can be swept into the filtering tank 13 through the dust opening 125, with less substances residue and high cleanliness.

[0082] According to some embodiments of the present disclosure, the support body 27 comprises a bottom cover 271 rotatably arranged around the fixing seat 26 and a connection body 272. Exemplarily, the bottom cover 271 is formed with a through hole at a middle region of the bottom cover 271 in the up-down direction, and an annular retaining ring is formed at a side of the fixing seat 26 away from the bottom surface of the washing tank 111. The annular retaining ring has a diameter greater than a diameter of the through hole. During mounting, the fixing seat 26 may be first arranged around the through hole and then fixed at the bottom surface of the washing tank 111. In this way, the bottom cover 271 can be restricted from being separated from the fixing seat 26 during rotation of the bottom cover 271. As a result, the structure is compact, and operation stability is good. In some embodiments, the bottom cover 271 is in clearance fit with the fixing seat 26. In this way, it can be ensured that the bottom cover 271 is rotatable relative to the fixing seat 26.

[0083] The support arm 28 is disposed at a circumferential surface of the connection body 272. One of the bottom cover 271 and the connection body 272 is formed with a limit block 2711, and another one of the bottom cover 271 and the connection body 272 is formed with a limit slot 2721. Exemplarily, the bottom cover 271 is formed with three limit blocks 2711 extending outwards at an outer periphery of the bottom cover 271 close to the connection body 272. The three limit blocks 2711 are circumferentially arranged at intervals of 120°. The connection body 272 is formed with three limit slots 2721 at a peripheral side wall of the connection body 272. The three limit slots 2721 are circumferentially arranged at intervals of 120°. The limit blocks 2711 are engaged into the limit slots 2721 to limit relative rotation between the connection body 272 and the base. In this way, the structure is compact.

[0084] According to some embodiments of the present disclosure, the support body 27 is a flexible structure. Exemplarily, a material of the support body 27 may be of a structure made of a flexible material such as soft glue, such as silicone or rubber. A lower surface of the support body 27 is formed with a shielding strip 2712 has an annular shape. The shielding strip 2712 surrounds an outer periphery of the fixing seat 26 and abuts with the bottom surface of the washing tank 111. Exemplarily, the bottom cover 271 is formed with the shielding strip 2712 of an annular shape at a side of the bottom cover 271 away from the limit block 2711. In this way, the shielding strip 2712 constantly keeps in contact with the bottom surface of the washing tank 111 during the rotation of the washing member 2. On the one hand, it is possible to prevent the substances from entering a rotation center and causing jamming. On the other hand, it is possible to protect the bottom cover 271 and the fixing seat 26 to a certain extent. As a result, service life and operation stability are improved.

[0085] According to some embodiments of the present disclosure, the support arm 28 is configured with a first washing structure 213 at the lower surface of the support arm 28. The lower surface of the first washing structure 213 is the sweeping surface 2b. The first washing structure 213 may be made of a flexible material such as soft glue, like silicone or rubber. In this way, on the one hand, it is possible to further improve an ability to washing the washing tank 111, allowing satisfactory cleaning. On the other hand, damage to the bottom surface of the washing tank 111 can also be reduced by using the first washing structure 213 to improve service life of the washing tank 111.

[0086] The flexible material refers to a material that can be squeezed and deformed.

[0087] Exemplarily, according to some embodiments of the present disclosure, the shape of the first washing structure 213 is not limited, for example, it may be elongated.

[0088] Exemplarily, according to some embodiments of the present disclosure, the first washing structure 213 may be connected to the support arm 28 in such a manner that the lower surface of the support arm 28 is formed with a limit recess having a gradually changing groove width. In this way, the first washing structure 213 may be inserted into the limit recess from a side of the limit recess having a larger width to complete a mounting of the first washing structure 213. When removal and replacement are needed, it is only necessary to pull out the first washing structure 213 from the side of the limit recess having the larger width, which facilitates easy assembling and disassembling. In some embodiments, the first washing structure 213 may also be connected to the support arm 28 through screwing and other manners.

[0089] According to some embodiments of the present disclosure, the washing surface 2a is formed with a washing protrusion 25. Exemplarily, a shape of the washing protrusion 25 is not limited. For example, the washing protrusion 25 may be truncated cone-shaped, cylindrical, or elongated, etc. In other exemplary embodiments of the present disclosure, the washing protrusions 25 of various shapes may be mixed, for example, comprising both an elongated washing protrusion 25 and a truncated cone-shaped washing protrusion 25. The specific shape is mainly based on a type of substances. That is, a special washing protrusion 25 may also be provided for a special type of substances to attain the purpose of cleaning.

[0090] According to some embodiments of the present disclosure, the washing member 2 comprises a second washing structure 214. A cleaning brush is disposed at an end of the support arm 28 away from the support body 27. The second washing structure 214 is in contact with a side wall surface of the washing tank 111. Exemplarily, the second washing structure 214 may be a bundle of straight hairs. In this way, side walls and corners of the washing tank 111 may be cleaned, with good cleaning ability and more thorough cleaning. It can be understood that due to a centrifugal force during the rotation, a part of the substances on the washing tank 111 can be thrown onto the side wall surface of the washing tank 111. In this way, these edges and corners cannot be cleaned only by the first washing structure 213.

[0091] According to some embodiments of the present disclosure, the washing member 2 has a first washing state and a second washing state. At the first washing state, the washing member 2 is fixed relative to the base 1, and the washing member 2 is configured to wash the mopping member 200 of the cleaning device. At the second washing state, the washing member 2 is movable and washes the at least one washing tank 111 when the washing member 2 moves. That is, the mopping member 200 may be driven into the washing tank 111 by the cleaning device when the mopping member 200 of the cleaning device needs washing. A relative movement between the mopping member 200 and the washing member 2 fixed relative to the base 1 can occur by providing the cleaning device to drive the mopping member 200. Therefore, the washing member 2 can clean the mopping member 200 more comprehensively to improve a washing effect of the cleaning base station 100 on the mopping member 200. In this case, the cleaning base station 100 is in a mopping member washing mode, and the cleaning device can carry the mopping member 200 to continue with the cleaning operation. In this way, it is beneficial to improving the cleaning effect of the cleaning device. In a specific example, after the mopping member 200 enters the washing tank 111, it may be pressed against the washing member 2. Therefore, when the washing member 2 is in the first washing state, a relative movement and friction between the moving mopping member 200 and the fixed washing member 2 occurs, allowing the washing member 2 to remove the dirt on the mopping member 200 by means of the relative friction between the washing member 2 and the mopping member 200 to realize the washing operation of the cleaning base station 100 on the mopping member 200.

[0092] Further, the washing member 2 movably cleans the washing tank 111 in the second washing state. It can be understood that the washing tank 111 can receive the dirt falling off from the mopping member 200 in the process of the base station 100 cleaning the mopping member 200. Therefore, dirt generated during the washing of the mopping member 200 can be better prevented from overflowing. Thus, the dirt can be better prevented from contaminating a space where the cleaning base station 100 is located. Therefore, after the washing of the mopping member 200 is completed, the washing member 2 can be controlled to be switched to the second washing state to clean the washing tank 111 by the washing member 2. In this case, the cleaning base station 100 is in a washing tank washing mode. Meanwhile, when the washing member 2 moves relative to the washing tank 111, it may stir the dirt in the washing tank 111 to flow into the filtering assembly for the subsequent treatment. Therefore, the cleaning base station 100 can achieve self-cleaning of the washing tank 111, which can prevent the dirt generated in the washing tank 111 from accumulating during the washing of the mopping member 200, and thus can prevent growth of the mud or the dirt due to the accumulation of the dirt in the washing tank 111. In this way, it is beneficial to improving the cleanliness of the washing tank 111. Meanwhile, a frequency of the user to clean the washing tank 111 can be reduced. In this way, it is beneficial to improving the user experience.

[0093] Therefore, the cleaning base station 100 can flexibly control the washing member 2 to switch between the first washing state and the second washing state according to needs of cleaning the mopping member 200 or the washing tank 111. Thus, the operations of the user during use of the cleaning device and the cleaning base station 100 can be reduced. In this way, it is beneficial to improving the user experience.

[0094] According to some embodiments of the present disclosure, the cleaning base station 100 further comprises a limiting member 3 configured to limit the washing member 2. At the first washing state, the limiting member 3 is engaged with the washing member 2 to fix the washing member 2 relative to the base 1. That is, the movement of the washing member 2 relative to the washing tank 111 can be better limited through the engagement between the limiting member 3 and the washing member 2. That is, in this case, the washing member 2 is limited by the limiting member 3. Thus, the mopping member 200 can be driven into the washing tank 111 by the cleaning device when the mopping member 200 of the cleaning device needs washing. Further, the relative movement between the mopping member 200 and the washing member 2 can occur by providing the cleaning device to drive the mopping member 200. Therefore, the washing member 2 can clean the mopping member 200 more comprehensively to improve the cleaning effect of the cleaning base station 100 on the mopping member 200. In this case, the cleaning base station 100 is in the mopping member washing mode, and the cleaning device can carry the washed mopping member 200 to continue with the cleaning operation. In this way, it is beneficial to improving the cleaning effect of the cleaning device.

[0095] At the second washing state, the limiting member 3 is disengaged from the washing member 2. It can be understood that the dirt falling off from the mopping member 200 can be received in the washing tank 111 in the process of the base station 100 cleaning the mopping member 200. Therefore, the dirt generated during the washing of the mopping member 200 can be better prevented from overflowing. Thus, the dirt can be better prevented from contaminating the space where the cleaning base station 100 is located. Therefore, after the washing of the mopping member 200 is completed, the washing member 2 can enter the second washing state to clean the washing tank 111 through the disengagement between the limiting member 3 and the washing member 2. In this case, the cleaning base station 100 is in the washing tank washing mode. Thus, the cleaning base station 100 can achieve the self-cleaning of the washing tank 111, which can prevent the dirt generated in the washing tank 111 from accumulating during the washing of the mopping member 200, and thus can prevent the growth of the mud or the dirt due to the accumulation of the dirt in the washing tank 111. In this way, it is beneficial to improving the cleanliness of the washing tank 111. Meanwhile, the frequency of the user to clean the washing tank 111 can be reduced. In this way, it is beneficial to improving the user experience.

[0096] That is, the cleaning base station 100 can realize the switching of the washing member 2 between the first washing state and the second washing state by controlling the limiting member 3, eliminating a need to change a movement direction of the mopping member 200 when the washing member 2 is switched between the first washing state and the second washing state. Therefore, requirements of the cleaning base station 100 for the cleaning device can be better reduced. As a result, it is beneficial to improving application scope of the cleaning base station 100.

[0097] According to some embodiments of the present disclosure, the washing member 2 is rotatably disposed in the washing tank 111, and the washing member 2 comprises the washing member body 21 and a rotary shaft 22. The washing tank 111 is formed with a rotation hole 112 at a bottom wall of the washing tank 111, and the rotary shaft 22 is rotatably engaged with the rotation hole 112. The washing member body 21 is located in the washing tank 111. That is, through the engagement between the rotary shaft 22 and the rotation hole 112, the washing member 2 is rotatable relative to the washing tank 111 while better ensuring stability of the washing member 2 when rotating relative to the washing tank 111. In addition, when the washing member 2 rotates relative to the washing tank 111, the dirt in the washing tank 111 can be better washed by the washing member body 21 while increasing an area swept by the washing member body 21 during the rotation of the washing member body 21, in a rotation direction of the washing member 2. In this way, it is beneficial to improving the washing effect of the washing member 2 on the washing tank 111.

[0098] At the first washing state, the suction nozzle 7 abuts with the washing member body 21 in a rotation direction of the washing member 2 to fix the washing member 2 relative to the base 1. That is, at the first washing state, at least part of the suction nozzle 7 is located at a side of the washing member 2 in the rotation direction of the washing member 2 or within coverage of the washing member 2. Therefore, the rotation of the washing member 2 is blocked by the part of the suction nozzle 7 located at the side of the washing member 2 in the rotation direction of the washing member 2 or within the coverage of the washing member 2. That is, the washing member 2 is fixed relative to relative to the base 1. As a result, the mopping member 200 can move relative to the washing member 2 under the driving of the cleaning device to achieve the washing operation of the mopping member 200 by the washing member 2. At the second washing state, the restriction of the suction nozzle 7 on the rotation of the washing member 2 can be lifted by withdrawing the part of the suction nozzle 7 located at the side of the washing member 2 in the rotation direction of the washing member 2 or within the coverage of the washing member 2. That is, the washing member 2 is rotatable freely relative to the washing tank 111. As a result, the washing member 2 can clean the washing tank 111 as it rotates.

[0099] In some embodiments, the cleaning device may drive the mopping member 200 to rotate, and a rotation axis of the mopping member 200 extends in the up-down direction. Since the mopping member 200 is driven by the cleaning device to rotate relative to the washing member 2 that is fixed by the suction nozzle 7. That is, at the first washing state, the washing member 2 can remove the dirt on the mopping member 200 through the relative movement and friction between the washing member 2 and the mopping member 200. When the washing member 2 is in the second washing state, the washing member 2 is automatically rotatable relative to the base 1. Since the mopping member 200 is pressed against the washing member 2, the cleaning device can drive the mopping member 200 and drive the washing member 2 to rotate in the washing tank 111 through the friction between the mopping member 200 and the washing member 2, to achieve the washing and wiping operations of the washing tank 111. As a result, the cooperation between the mopping member 200 and the washing member 2 is in a simple manner to facilitate simplifying the structures of the mopping member 200 and the washing member 2. In addition, when the washing member 2 is in the first washing state, the cleaning device can drive the mopping member to rotate forwards or in reverse, thus allowing the washing member 2 to wash the mopping member 200 clockwise or counterclockwise. When the washing member 2 is in the second washing state, the cleaning device can drive the mopping member to rotate forwards or in reverse to drive the washing member 2 to rotate forwards or in reverse, thus allowing the washing member 2 to clean the washing tank 111 clockwise or counterclockwise. In this way, it is beneficial to improving a cleaning effect of the mopping member and the washing tank 111.

[0100] In some embodiments, the washing member body 21 comprises the support body 27 rotatably disposed in the washing tank 111 by rotation and the support arm 28 disposed at a circumferential surface of the support body 27. The support arm 28 is formed with the washing surface 2a at an upper surface of the support arm 28 and the sweeping surface 2b at a lower surface of the support arm 28. At the first washing state, the suction nozzle 7 abuts with the support arm 28 in the rotation direction of the washing member 2.

[0101] According to some embodiments of the present disclosure, the base 1 has two washing tanks 111 arranged in the left-right direction, and the washing member 2 is rotatably disposed in each of the two washing tanks 111. In this way, it is possible to better increase the area swept by the washing member 2 during the rotation of the washing member 2. As a result, it is beneficial to improving the washing effect of the washing member 2 on the washing tank 111 while enhancing efficiency of the washing member 2 agitating the dirt in the washing tank 111 to flow into the filtering tank 13. The limiting member 3 is disposed at the base 1 and located between the two washing tanks 111. At the first washing state, at least part of the limiting member 3 is located within a rotation range of the washing member 2 in each of the two washing tanks 111. That is, the rotation of the washing member 2 can be better blocked by the part of the limiting member 3 located in each of the two washing members 2. The limiting member 3 may be configured to limit a movement of the washing members 2 in the two washing tanks 111 relative to the washing tank 111. That is, the two washing members 2 can be limited by one limiting member 3. Therefore, the number of limiters 3 can be better reduced. Meanwhile, the limiting member 3 can fully utilize a space between the two washing tanks 111 to allow for a compact internal layout of the cleaning base station 100.

[0102] At the first washing state, the limiting member 3 is engaged with the washing member 2 to fix the washing member 2 relative to the base 1. That is, the movement of the washing member 2 relative to the washing tank 111 can be better limited through the engagement between the limiting member 3 and the washing member 2. That is, in this case, the washing member 2 in each of the two washing tank 111 is limited by the limiting member 3. Thus, the mopping member 200 can be driven into the washing tank 111 by the cleaning device when the mopping member 200 of the cleaning device needs washing. Further, the relative movement between the mopping member 200 and the washing member 2 can occur by providing the cleaning device to drive the mopping member 200. Therefore, the washing member 2 can clean the mopping member 200 more comprehensively to improve the cleaning effect of the cleaning base station 100 on the mopping member 200. In this case, the cleaning base station 100 is in the mopping member washing mode, and the cleaning device can carry the washed mopping member 200 to continue with the cleaning operation. In this way, it is beneficial to improving the cleaning effect of the cleaning device. In a specific example, after the cleaning device enters the cleaning base station 100, the two mopping members 200 of the cleaning device respectively enter the two washing tanks 111 and are pressed against the washing members 2 in the two washing tanks 111. Therefore, after the two washing members 2 are fixed by the limiting member 3, a relative movement and friction between the moving mopping member 200 and the fixed washing member 2 occurs, allowing the washing member 2 to remove the dirt on the mopping member 200 by means of the relative friction between the washing member 2 and the mopping member 200 to realize the washing operation of the cleaning base station 100 on the mopping member 200.

[0103] At the second washing state, the limiting member 3 is disengaged from the washing member 2. It can be understood that the washing tank 111 can receive the dirt falling off from the mopping member 200 in the process of the base station 100 cleaning the mopping member 200. Therefore, the dirt generated during the washing of the mopping member 200 can be better prevented from overflowing. Thus, the dirt can be better prevented from contaminating the space where the cleaning base station 100 is located. Therefore, after the washing of the mopping member 200 is completed, each of the two washing members 2 can enter the second washing state to clean the washing tank 111 through the disengagement between the limiting member 3 and the two washing members 2. In this case, the cleaning base station 100 is in the washing tank washing mode. Thus, the cleaning base station 100 can achieve the self-cleaning of the washing tank 111, which can prevent the dirt generated in the washing tank 111 from accumulating during the washing of the mopping member 200, and thus can prevent the growth of the mud or the dirt due to the accumulation of the dirt in the washing tank 111. In this way, it is beneficial to improving the cleanliness of the washing tank 111. Meanwhile, the frequency of the user to clean the washing tank 111 can be reduced. In this way, it is beneficial to improving the user experience.

[0104] According to some embodiments of the present disclosure, the limiting member 3 is formed with a water feeding channel 3c at an upper surface of the limiting member 3, and the cleaning base station 100 comprises a water feeding nozzle 15 configured to feed water into the water feeding channel 3c. Exemplarily, the water feeding nozzle 15 comprises a water supply hole 114 and two fixed screw holes 15a. The water supply hole 114 is located in a middle of the two fixed screw holes 15a. The two fixed screw holes 15a are fixed to at a side wall surface of the washing tank 111 by fasteners such as screws or bolts, and the water supply hole 114 is located above the water feeding channel 3c. In this way, clean water is provided for subsequent washing of the mopping member 200 by feeding water downwards into the water feeding channel 3c.

[0105] Exemplarily, according to some embodiments of the present disclosure, the cleaning base station 100 is further provided with a water supply box 10a, and the water feeding nozzle 15 further comprises a connection hole 15b. The water supply box 10a is connected to the connection hole 15b by a tube channel, which can provide a continuous source of clean water for the water feeding channel 3c.

[0106] According to some embodiments of the present disclosure, the washing surface 2a is formed with a water outlet channel 23, and the water feeding channel 3c is in communication with the water outlet channel 23 when the washing member 2 abuts with the limiting member 3. Exemplarily, when the washing member 2 is in an abutting state, for example, when the washing member 2 abuts with a forward rotation limit surface 3a and / or a reverse rotation limit surface 3b, a tail end of the water feeding channel 3c is in communication with a head end of the water outlet channel 23. In this way, clean water may flow into the water outlet channel 23 through the water feeding channel 3c to wet and wash the mopping member 200. When the washing member 2 is in an avoidance state, clean water may flow into the washing tank 111 through the water feeding channel 3c to wet some lighter and smaller garbage such as dust or paper, to facilitate subsequent washing and sweeping of the sweeping surface 2b.

[0107] According to some embodiments of the present disclosure, the filtering tank 13 is located at an outer peripheral side of the washing tank 111. Thus, the filtering tank 13 and the washing tank 111 can fully utilize a space of the base 1 in the horizontal direction. As a result, a space occupied by the filtering tank 13 and the washing tank 111 in the up-down direction can be better reduced to facilitate controlling a thickness of the base 1 in the up-down direction. In this way, the layout is reasonable. In addition, each of the filtering structure and the sewage buffer chamber 14 is located at the outer peripheral side of the washing tank 111. Therefore, the washing members 2 and other structures in the washing tank 111 can be better prevented from being blocked above the filtering tank 13 to facilitate reducing difficulty in cleaning the filtering structure and the sewage buffer chamber 14.

[0108] The washing tank 111 is formed with a communication notch 113 at a peripheral wall of the washing tank 111, and the filtering tank 13 is in communication with the washing tank 111 through the communication notch 113. That is, the communication notch 113 is located between the washing tank 111 and the filtering tank 13 and horizontally extends through the peripheral wall of the washing tank 111. Therefore, a water flow passage that brings the washing tank 111 into communication with the filtering tank 13 can be formed between the washing tank 111 and the filtering tank 13. Thus, the dirt in the washing tank 111 can smoothly enter the filtering tank 13 through the communication notch 113 for the separation of the sewage from the solid dirt.

[0109] Further, the cleaning base station 100 further comprises a drying and collecting assembly disposed at the base 1. The drying and collecting assembly is configured to dry and collect solid dirt in the filtering tank 13 and comprises a suction nozzle 7. The filtering component has the filtering tank 13 in communication with the washing tank 111. The suction nozzle 7 is movably located in the filtering tank 13. The solid dirt in the filtering tank 13 is adapted to be sucked into the drying and collecting assembly through the suction nozzle 7. That is, the suction nozzle 7 is movable relative to the filtering tank 13. Therefore, a position of the suction nozzle 7 in the filtering tank 13 can be adjusted by driving the suction nozzle 7 to move. Thus, the drying and collecting assembly can collect solid dirt located at different positions in the filtering tank 13 through the suction nozzle 7. In addition, a distance between the suction nozzle 7 and the solid dirt in the filtering tank 13 can be better shortened by providing the suction nozzle 7 in the filtering tank 13. Thus, a suction force of the drying and collecting assembly exerted on the solid dirt in the filtering tank 13 can be improved. As a result, a collection effect of the drying and collecting assembly on the solid dirt in the filtering tank 13 can be improved. In this way, it is beneficial to improving cleanliness of the filtering tank 13.

[0110] The suction nozzle 7 is constructed as the limiting member 3. At the first washing state, the suction nozzle 7 is engaged with the washing member 2 (that is, the suction nozzle 7 is located within a movement range of the washing member 2 to limit the washing member 2) to fix the washing member 2 relative to the base 1, and the washing member 2 is configured to wash the mopping member 200 of the cleaning device. At the second washing state, the suction nozzle 7 is disengaged from the washing member 2, and the washing member 2 is movable and washes the at least one washing tank 111 when the washing member 2 moves. That is, at the first washing state, the suction nozzle 7 is engaged with the washing member 2. That is, the suction nozzle 7 is located within the movement range of the washing member 2 to limit the washing member 2 to fix the washing member 2 relative to the base 1. The washing member 2 is configured to wash the mopping member 200 of the cleaning device. At the second washing state, the suction nozzle 7 is disengaged from the washing member 2, and the washing member 2 is movable and washes the at least one washing tank 111 when the washing member 2 moves. Thus, the suction nozzle 7 can improve the collection effect of the drying and collecting assembly on the solid dirt in the filtering tank 13 while controlling the washing member 2 to switch between the first washing state and the second washing state through the engagement between the suction nozzle 7 and the washing member 2. That is, the suction nozzle 7 has both the functions of sucking the solid dirt and limiting, which has high integration. Therefore, the number of components of the cleaning base station 100 can be better reduced to facilitate simplifying the structure of the cleaning base station 100.

[0111] In an exemplary embodiment of the present disclosure, the movement of the washing member 2 relative to the washing tank 111 can be better limited through the engagement between suction nozzle 7 and the washing member 2. Thus, the mopping member 200 can be driven into the washing tank 111 by the cleaning device when the mopping member 200 of the cleaning device needs to be washed. Further, the relative movement between the mopping member 200 and the washing member 2 can occur by providing the cleaning device to drive the mopping member 200. Therefore, the washing member 2 can clean the mopping member 200 more comprehensively to improve the cleaning effect of the cleaning base station 100 on the mopping member 200. In this case, the cleaning base station 100 is in the mopping member washing mode, and the cleaning device can carry the washed mopping member 200 to continue with the cleaning operation. In this way, it is beneficial to improving the cleaning effect of the cleaning device. In a specific example, after the mopping member 200 enters the washing tank 111, it may be pressed against the washing member 2. Therefore, when the washing member 2 is fixed by the suction nozzle 7, a relative movement and friction between the moving mopping member 200 and the fixed washing member 2 occurs, allowing the washing member 2 to remove the dirt on the mopping member 200 by means of the relative friction between the washing member 2 and the mopping member 200 to realize the washing operation of the cleaning base station 100 on the mopping member 200.

[0112] The washing tank 111 can receive dirt falling off from the mopping member 200 in the process of the base station 100 cleaning the mopping member 200. Therefore, the dirt generated during the washing of the mopping member 200 can be better prevented from overflowing. Thus, the dirt can be better prevented from contaminating the space where the cleaning base station 100 is located. Therefore, after the washing of the mopping member 200 is completed, it is possible to enter the second washing state through the disengagement between the suction nozzle 7 and the washing member 2 to clean the washing tank 111 by the washing member 2. In this case, the cleaning base station 100 is in the washing tank washing mode. That is, the cleaning base station 100 can achieve the self-cleaning of the washing tank 111, which can prevent the dirt generated in the washing tank 111 from accumulating during the washing of the mopping member 200, and thus can prevent the growth of the mud or the dirt due to the accumulation of the dirt in the washing tank 111. In this way, it is beneficial to improving the cleanliness of the washing tank 111. Meanwhile, the frequency of the user to clean the washing tank 111 can be reduced. In this way, it is beneficial to improving the user experience.

[0113] Thus, the cleaning base station 100 can realize the switching of the washing member 2 between the first washing state and the second washing state by controlling the suction nozzle 7, eliminating the need to change the movement direction of the mopping member 200 when the washing member 2 is switched between the first washing state and the second washing state. Therefore, the requirements of the cleaning base station 100 for the cleaning device can be better reduced. As a result, it is beneficial to improving the application scope of the cleaning base station 100.

[0114] According to some embodiments of the present disclosure, the washing member 2 is rotatably disposed in the washing tank 111, and a region swept by the washing member 2 during rotation of the washing member 2 is a washing region. At the first washing state, a part of the suction nozzle 7 located in the washing region is a limit portion 31. The limit portion 31 abuts with the washing member 2 in a rotation direction of the washing member 2. Thus, the rotation of the washing member 2 relative to the washing tank 111 can be better blocked through the abutment of the limit portion 31 with the washing member 2. Further, an upper surface of at least the limit portion 31 of the suction nozzle 7 is lower than or flushed with an upper surface of the washing member 2. That is, at the first washing state, the upper surface of at least the limit portion 31 at the suction nozzle 7 is lower than or flushed with the upper surface of the washing member 2. For example, the upper surface of the limit portion 31 may be flush with the upper surface of the washing member 2 or may be lower than the upper surface of the washing member 2. Thus, when the mopping member 200 rotates relative to the washing member 2 in the first washing state, the limit portion 31 can be prevented from blocking the rotation of the mopping member 200. As a result, rotation resistance of the mopping member 200 can be better reduced, which facilitates an increase in a rotational speed of the mopping member 200 to ensure washing efficiency.

[0115] According to some embodiments of the present disclosure, the washing member 2 is rotatably disposed in the washing tank 111 and comprises the washing member body 21 and the rotary shaft 22. The washing tank 111 is formed with the rotation hole 112 at the bottom wall of the washing tank 111. The rotary shaft 22 is rotatably engaged into the rotation hole 112. The washing member body 21 is located in the washing tank 111. At the first washing state, the part of the suction nozzle 7 located in the washing region is the limit portion 31. The limit portion 31 abuts with the washing member body 21 in the rotation direction of the washing member 2. That is, dirt in the washing region can be cleaned by the washing member 2. At the first washing state, the limit portion 31 is located at a side of the washing member body 21 or within the coverage of the washing member body 21 in a rotation direction of the washing member body 21. Therefore, the rotation of the washing member 2 relative to the washing tank 111 can be better blocked through the abutment of the limit portion 31 with the washing member body 21.

[0116] According to some embodiments of the present disclosure, the suction nozzle 7 is movable between a limiting position and a non-limiting position. The suction nozzle 7 is engaged with the washing member 2 when the suction nozzle 7 is in the limiting position, and the suction nozzle 7 is disengaged from the washing member 2 when the suction nozzle 7 is in the non-limiting position. That is, when the suction nozzle 7 moves to the limiting position, the suction nozzle 7 can restrict the rotation of the washing member 2 relative to the washing tank 111, allowing the washing member 2 to be fixed relative to the base 1. In this case, the washing member 2 is in the first washing state. When the suction nozzle 7 moves to the non-limiting position, the restriction of the suction nozzle 7 on the washing member 2 is lifted, allowing the washing member 2 to move relative to the washing tank 111 to clean the washing tank 111 by the washing member 2. In this case, the washing member 2 is in the second washing state. That is, the washing member 2 can be switched between the first washing state and the second washing state by moving the suction nozzle 7 between the limiting position and the non-limiting position. In this way, it is possible to reduce difficulty in switching the washing member 2 between the first washing state and the second washing state while eliminating the need to change the movement direction of the mopping member 200. Therefore, the requirements of the cleaning base station 100 for the cleaning device can be better reduced. As a result, it is beneficial to improving the application scope of the cleaning base station 100.

[0117] Further, the washing member 2 is rotatably disposed in the washing tank 111, and a region swept by the washing member 2 during rotation of the washing member 2 is a washing region. When the suction nozzle 7 is in the limiting position, at least part of the suction nozzle 7 is located in the washing region, and when the suction nozzle 7 is in the non-limiting position, the suction nozzle 7 is located at an outer peripheral side of the washing region. Thus, the rotation of the washing member 2 relative to the washing tank 111 can be blocked by the part of the suction nozzle 7 located in the washing region, to keep the washing member 2 in the first washing state. Meanwhile, the suction nozzle 7 in the non-limiting position can be better prevented from interfering with the washing member 2. Thus, the suction nozzle 7 in the non-limiting position can be better prevented from blocking the rotation of the washing member 2, allowing the washing member 2 to be kept in the second washing state where the washing member 2 is rotatable relative to the washing tank 111.

[0118] According to some embodiments of the present disclosure, the cleaning base station 100 further comprises the drying and collecting assembly disposed at the base 1, and the filtering assembly has the filtering tank 13 in communication with the washing tank 111. The drying and collecting assembly is configured to dry and collect solid dirt in the filtering tank 13. Thus, the solid dirt is dried and easily separated from the filtering tank 13 by the drying and collecting assembly drying the solid dirt in the filtering tank 13. Therefore, difficulty of the drying and collecting assembly in recovering the solid dirt in the filtering tank 13 can be better reduced while better preventing the drying and collecting assembly from directly collecting wet solid dirt, which would otherwise result in growth of mud or bacteria due to a long-term damp environment inside the drying and collecting assembly. In this way, it is beneficial to improving cleanliness of the environment inside the drying and collecting assembly. Moreover, the dried solid dirt in the filtering tank 13 can be collected by the drying and collecting assembly. Therefore, the solid dirt can be better prevented from accumulating in the filtering tank 13, which would otherwise block the filtering structure and meanwhile affect the flowing of the dirt in the washing tank 111 into the filtering tank 13. In addition, in the process of the drying and collecting assembly drying the solid dirt, drying treatment of the filtering tank 13 can be realized simultaneously, which may ensure that the filtering tank 13 is in a dry state. Thus, the growth of mud or bacteria due to the long-term damp environment inside the filtering tank 13 can be avoided. In this way, it is beneficial to improving a cleaning effect of the drying and collecting assembly on the filtering tank 13 to ensure cleanliness of the filtering tank 13.

[0119] According to some embodiments of the present disclosure, the base 1 has two washing tanks 111 arranged in the left-right direction, and at least part of the drying and collecting assembly is located between the two washing tanks 111. The drying and collecting assembly may be completely located between the two washing tanks 111, or a part of the drying and collecting assembly may be located between the two washing tanks 111, and no specific restrictions are made herein. Thus, the drying and collecting assembly can fully utilize a mounting space between the two washing tanks 111. As a result, the layout of the cleaning base station 100 is compact. Meanwhile, a distance between the drying and collecting assembly and the filtering tank 13 located between the two washing tanks 111 can be shortened to facilitate the cooperation between the drying and collecting assembly and the filtering tank 13, to dry and collect the solid dirt in the filtering tank 13. In this way, the layout is reasonable.

[0120] According to some embodiments of the present disclosure, the drying and collecting assembly comprises the suction nozzle 7 movably located in the filtering tank 13, and the solid dirt in the filtering tank 13 is adapted to be sucked into the drying and collecting assembly through the suction nozzle 7. That is, the suction nozzle 7 is movable relative to the filtering tank 13. Therefore, a position of the suction nozzle 7 in the filtering tank 13 can be adjusted by driving the suction nozzle 7 to move. Thus, the drying and collecting assembly can collect solid dirt located at different positions in the filtering tank 13 through the suction nozzle 7. In addition, a distance between the suction nozzle 7 and the solid dirt in the filtering tank 13 can be better shortened by providing the suction nozzle 7 in the filtering tank 13. Thus, a suction force of a collecting assembly exerted on the solid dirt in the filtering tank 13 can be improved. As a result, a collection effect of the collecting assembly on the solid dirt in the filtering tank 13 can be improved. In this way, it is beneficial to improving cleanliness of the filtering tank 13.

[0121] According to some embodiments of the present disclosure, the cleaning base station 100 further comprises a drive mechanism 9 disposed at the base 1 and connected to the suction nozzle 7, and the solid dirt in the filtering tank 13 is adapted to be sucked into the drying and collecting assembly through the suction nozzle 7. That is, the suction nozzle 7 can be driven to move in the filtering tank by the drive mechanism 9 to adjust a position of the suction nozzle 7 in the filtering tank 13. In this way, the distance between the suction nozzle 7 and the solid dirt in the filtering tank 13 can be better shortened. Therefore, the suction force of the drying and collecting assembly exerted on the solid dirt in the filtering tank 13 can be better improved. Further, the collection effect of the drying and collecting assembly on the solid dirt in the filtering tank 13 can be better improved. As a result, it is beneficial to improving the cleanliness in the filtering tank 13 and an automation level of the position adjustment of the suction nozzle 7. In a specific example, the suction nozzle 7 has a scraping wall 712 abutting with the bottom wall of the filtering tank 13. Therefore, solid dirt on the bottom wall of the filtering tank 13 can be scraped by the scratching wall 712 when the suction nozzle 7 moves relative to the filtering tank 13, allowing the solid dirt to be separated from the bottom wall of the filtering tank 13. In this way, the solid dirt separated from the filtering tank 13 is easily collected by the drying and collecting assembly. As a result, it is beneficial to improving the collection effect of the drying and collecting assembly on the solid dirt. It should be noted that the mounting position of the drive mechanism 9 may be set at any reasonable position according to design requirements. For example, the drive mechanism 9 may also be disposed above the base 1 or may also be disposed below the base 1, etc., and the mounting position of the drive mechanism 9 is not specifically limited herein.

[0122] Further, the drive mechanism 9 is configured to drive the suction nozzle 7 to move in a suction direction of a suction inlet 711 of the suction nozzle 7. That is, the suction nozzle 7 is movable, and in the suction direction of the suction inlet 711, the drive mechanism 9 can drive the suction nozzle 7 to move to adjust the position of the suction nozzle 7 in the filtering tank 13. Therefore, the position of the suction inlet 711 of the suction nozzle 7 in the filtering tank 13 can be better adjusted. Thus, the collecting assembly can collect the solid dirt at the different positions in the filtering tank 13 through the suction inlet 711 of the suction nozzle 7. In this way, it is beneficial to improving the collection effect of the collecting assembly on the solid dirt in the filtering tank 13 through the suction nozzle 7. In some other embodiments, the filtering tank 13 has the filtering component 12 at a bottom wall of the filtering tank 13, and the filtering component 12 is formed as the filtering structure. The drive mechanism 9 is disposed at the base 1 and connected to the filtering component 12, and the drive mechanism 9 is configured to drive the filtering component 12 to move.

[0123] In a specific example, the base 1 has two washing tanks 111 arranged in the left-right direction, and the filtering tank 13 is located between the two washing tanks 111. Dirt in each of the two washing tanks 111 is adapted to flow into the filtering tank 13. That is, the filtering tank 13 can simultaneously receive the dirt in the two washing tanks 111. That is, the two washing tanks 111 can share one filtering tank 13. Therefore, the number of filtering tanks 13 can be better reduced to save the mounting space occupied by the filtering tanks 13, which facilitates controlling the overall size of the cleaning base station 100. In addition, the two washing tanks 111 can respectively wash two mopping members 200 of the cleaning device, which facilitates improving the cleaning efficiency of the cleaning base station 100 on the mopping members 200. The suction inlet 711 extends in the left-right direction, and the suction nozzle 7 is movable in a front-rear direction. Thus, a coverage area of the suction inlet 711 in the left-right direction can be better increased. As a result, the suction inlet 711 may suck in solid dirt distributed in the filtering tank 13 in the left-right direction, to improve the collection effect of the drying and collecting assembly on the solid dirt in the filtering tank 13. In addition, the suction nozzle 7 is movable in the front-rear direction, which may avoid the suction nozzle 7 blocking the dirt in the washing tanks 111 at left and right sides from flowing into the filtering tank 13. Thus, efficiency of the dirt in the washing tank 111 on the left and right sides entering the filtering tank 13 can be accelerated.

[0124] According to some embodiments of the present disclosure, the suction nozzle 7 is reciprocatable in the suction direction of the suction inlet 711. That is, the drive mechanism 9 may drive the suction nozzle 7 to move in the suction direction of the suction inlet 711 and may also drive the suction nozzle 7 to move in a direction opposite to the suction direction of the suction inlet 711. As a result, the suction nozzle 7 is reciprocatable relative to the filtering tank 13. Thus, in the process of the suction nozzle 7 reciprocating relative to the filtering tank 13, a collecting assembly can collect the solid dirt in the filtering tank 13 through the suction nozzle 7 multiple times, to improve a collection effect of the collecting assembly on the dirt in the filtering tank 13, and thus to ensure the cleanliness of the filtering tank 13.

[0125] According to some embodiments of the present disclosure, the drive mechanism 9 is located at an outer peripheral side of the base 1. Thus, the drive mechanism 9 can be better prevented from occupying the mounting space in the base 1. Therefore, a larger space can be reserved for the washing tank 111, the filtering tank 13, the sewage buffer chamber 14, etc. Moreover, the base 1 is in a relatively humid environment when cleaning the mopping member 200 and the washing tank 111. Therefore, by providing the drive mechanism 9 at the outer peripheral side of the base 1, the drive mechanism 9 can be prevented from being in contact with water in the base 1, which would otherwise lead to a short circuit. In this way, it is beneficial to improving stability and reliability of the drive mechanism 9.

[0126] According to some embodiments of the present disclosure, the filtering tank 13 comprises the filtering component 12 at a bottom wall of the filtering tank 13. The filtering component 12 is formed with the filtering structure, and the suction nozzle 7 and the filtering component 12 are movable relative to each other. Thus, the relative position of the suction nozzle 7 and the filtering component 12 can be better adjusted by moving the suction nozzle 7 relative to the filtering component 12. Therefore, the position of the suction inlet 711 of the suction nozzle 7 at the filtering component 12 can be better adjusted. As a result, the collecting assembly can collect the solid dirt located at different positions of the filtering component 12 through the suction nozzle 7. In this way, it is beneficial to improving the collection effect of the collecting assembly on the solid dirt in the filtering tank 13 through the suction nozzle 7. Meanwhile, the drying assembly can deliver hot water to the different positions of the filtering component 12 through the suction nozzle 7. In this way, it is beneficial to improving a drying effect of the drying assembly on the solid dirt in the filtering tank 13 through the suction nozzle 7. It may be that the suction nozzle 7 is movable, and therefore the suction nozzle 7 is movable relative to the filtering component 12. Further, it may be that the filtering component 12 is movable, and therefore the suction nozzle 7 is movable relative to the filtering component 12. Furthermore, it may be that each of the suction nozzle 7 and the filtering component 12 is movable, and therefore the suction nozzle 7 is movable relative to the filtering component 12, which is not limited herein.

[0127] According to some embodiments of the present disclosure, a suction inlet 711 of the suction nozzle 7 is of a flat-mouthed shape extending horizontally. Thus, a coverage area of the suction inlet 711 of the suction nozzle 7 in a horizontal direction can be better increased. Therefore, a dust suction region of the collecting assembly in the filtering tank 13 can be better improved, that is, the dust suction region of the collecting assembly may cover the filtering tank 13. In this way, it is beneficial to improving the collection effect of the collecting assembly on the solid dirt in the filtering tank 13. A length direction of the suction inlet 711 is perpendicular to a movement direction of the suction nozzle 7. That is, the drive mechanism 9 is adapted to drive the suction nozzle 7 to move in a direction perpendicular to the length direction of the suction inlet 711. As a result, in a process of the drive mechanism 9 driving the suction nozzle 7 to move, the dust suction region of the suction nozzle 7 may cover the filtering tank 13 to improve the collection effect of the collecting assembly on the solid dirt in the filtering tank 13 through the suction nozzle 7. In a specific example, the suction inlet 711 is of a flat-mouthed shape extending in the left-right direction, and the drive mechanism 9 is configured to drive the suction nozzle 7 to move in a front-rear direction. Therefore, in a process of the suction nozzle 7 moving in the front-rear direction, the suction inlet 711 may collect the solid dirt in the filtering tank 13 in the front-rear direction. Thus, the collecting assembly can collect the solid dirt in the filtering tank 13 more comprehensively and thoroughly through the suction nozzle 7 to improve the cleanliness in the filtering tank 13.

[0128] The suction inlet 711 of the suction nozzle 7 is inclined downwards. That is, the suction inlet 711 extends downwards in a direction opposite to an air flow direction of a collecting air duct 61. That is, an end of the suction inlet 711 close to the filtering tank 13 is lower than an end of the suction inlet 711 close to the collecting air duct 6. Therefore, the end of the suction inlet 711 close to the filtering tank 13 can be closer to the filtering structure. In this way, it is beneficial to improving a suction force of the collecting assembly on the solid dirt in the filtering tank 13 through the suction nozzle 7. In addition, an angle can be formed between the suction inlet 711 of the suction nozzle 7 and the bottom wall of the filtering tank 13, which may increase an area of the bottom wall of the filtering tank 13 opposite to the suction inlet 711 in an extending direction of the suction inlet 711. In this way, it is beneficial to further improving the suction force of the collecting assembly on the solid dirt in the filtering tank 13 through the suction nozzle 7.

[0129] According to some embodiments of the present disclosure, the suction inlet 711 of the suction nozzle 7 has a scraping wall 712 and a flow-guide wall 713 that are opposite to each other in the up-down direction. The scraping wall 712 is in contact with the bottom wall of the filtering tank 13, and an edge of the flow-guide wall 713 extends beyond an edge of the scraping wall 712. The edge of the flow-guide wall 713 herein refers to an edge of the flow-guide wall 713 away from an end of the collecting air duct member 6, and the edge of the scraping wall 712 herein refers to an edge of the scraping wall 712 away from the end of the collecting air duct member 6. That is, the edge of the flow-guide wall 713 extends out of the edge of the scraping wall 712, and therefore an area of the suction inlet 711 can be increased. As a result, a collection capacity of the collecting assembly to the solid dirt in the filtering tank 13 through the suction nozzle 7 can be better improved. In addition, the scraping wall 712 is in contact with a bottom wall of the filtering tank 13, and the suction nozzle 7 is movable relative to the bottom wall of the filtering tank 13. Therefore, the movement of the suction nozzle 7 may drive the scraping wall 712 to move relative to the bottom wall of the filtering tank 13. Thus, the solid dirt on the bottom wall of the filtering tank 13 can be scraped by the scraping wall 712, allowing the solid dirt attached to the bottom wall of the filtering tank 13 to be separated from the bottom wall of the filtering tank 13, to facilitate the collecting assembly to collect the solid dirt.

[0130] According to some embodiments of the present disclosure, a thickness of the scraping wall 712 gradually increases in a suction direction of the suction inlet 711. That is, a thickness of an upstream side of the scraping wall 712 gradually decreases in a direction from an end of the scraping wall 712 close to the collecting air duct member 6 to the end of the scraping wall 712 away from the collecting air duct member 6. That is, a thickness of the end of the scraping wall 712 away from the collecting air duct member 6, i.e., the thickness of the edge of the scraping wall 712 is smaller than a thickness of the end of the scraping wall 712 close to the collecting air duct member 6. Thus, it is possible for the edge of the scraping wall 712 to better reduce an obstruction of the solid dirt to the solid dirt by reducing the thickness of the edge of the scraping wall 712, which in turn can reduce resistance to the solid dirt in the filtering tank 13 to enter the suction inlet 711 along the scraping wall 712. That is, the solid dirt in the filtering tank 13 can smoothly enter the suction inlet 711 along the scraping wall 712. In this way, it is beneficial to improving the collection effect of the collecting assembly on the solid dirt in the filtering tank 13 through the suction nozzle 7.

[0131] According to some embodiments of the present disclosure, the flow-guide wall 713 extends obliquely upwards in a suction direction of the suction inlet 711. That is, an end of the flow-guide wall 713 away from the collecting air duct member 6, i.e., the edge of the flow-guide wall 713 is lower than an end of the flow-guide wall 713 close to the collecting air duct member 6. Thus, an angle can be formed between the suction inlet 711 of the suction nozzle 7 and the bottom wall of the filtering tank 13, which may increase an area of the bottom wall of the filtering tank 13 opposite to the suction inlet 711 in an extending direction of the suction inlet 711. In this way, it is beneficial to further improve the suction force of the collecting assembly on the solid dirt in the filtering tank 13 through the suction nozzle 7.

[0132] According to some embodiments of the present disclosure, the drying and collecting assembly comprises the collecting air duct 61 and a drying air duct 51. The collecting air duct 61 is configured to discharge solid dirt in the filtering tank 13, and the drying air duct 51 is configured to deliver heated air flow at least into the filtering tank 13. That is, the filtering tank 13 may be in communication with the drying air duct 51 and the collecting air duct 61. Hot air generated by the drying assembly may be delivered to the filtering tank 13 through the drying air duct 51 when the filtering tank 13 is in communication with the drying air duct 51, to realize drying treatment of the solid dirt in the filtering tank 13. The collecting assembly can collect the solid dirt in the filtering tank 13 through the collecting air duct 61 when the filtering tank 13 is in communication with the collecting air duct 61. Thus, mutual interference between drying air flow and collecting air flow can be avoided to ensure stability of the drying process and the collecting process.

[0133] The filtering tank 13 may be in selective communication with one of the collecting air duct 61 and the drying air duct 51. That is, it may be that the filtering tank 13 is controlled to be in communication with the drying air duct 51, and therefore the hot air generated by the drying assembly can be delivered to the filtering tank 13 through the drying air duct 51 to realize the drying treatment of the solid dirt in the filtering tank 13. Also, it may be that the filtering tank 13 is controlled to be in communication with the collecting air duct 61, and therefore the collecting assembly can collect the solid dirt in the filtering tank 13 through the collecting air duct 61. Thus, the mutual interference between drying air flow and collecting the air flow can be avoided to ensure the stability of the drying process and the collecting process.

[0134] According to some embodiments of the present disclosure, the drying air duct 51 is internally provided with a first control valve configured to control conduction and blocking of the drying air duct 51. That is, an air flow passage that brings the drying air duct 51 into communication with the filtering tank 13 is formed between the drying air duct 51 and the filtering tank 13 when the first control valve is configured to control the conduction of the drying air duct 51; and the air flow passage between the drying air duct 51 and the filtering tank 13 is blocked when the first control valve is configured to control the blocking of the drying air duct 5. The collecting air duct 61 is internally provided with a second control valve configured to control conduction and blocking of the collecting air duct 61. That is, an air flow passage that brings the collecting air duct 61 into communication with the filtering tank 13 is formed between the collecting air duct 61 and the filtering tank 13 when the second control valve is configured to control the conduction of the collecting air duct 61; and the air flow passage between the collecting air duct 61 and the filtering tank 13 is blocked when the second control valve is configured to control the blocking of the collecting air duct 61. Thus, the communication between the filtering tank 13 and the drying air duct 51 as well as the communication between the filtering tank 13 and the collecting air duct 61 can be better controlled by the first control valve and the second control valve. Therefore, performance of the drying and collecting assembly in the drying modes and the collecting mode can be better guaranteed.

[0135] In an exemplary embodiment of the present disclosure, when drying treatment is performed on the solid dirt, the conduction of the drying air duct 51 is controlled by the first control valve, and therefore the drying air duct 51 is in communication with the filtering tank 13. In this case, the hot air in the drying air duct 51 may be delivered to the filtering tank 13 to dry the solid dirt. Meanwhile, the blocking of the collecting air duct 61 may be controlled by the second control valve, and therefore the air flow passage between the filtering tank 13 and the collecting air duct 61 is blocked. In this way, the hot air can be better prevented from escaping to the collecting air duct 61 through the filtering tank 13, which would otherwise affect the drying effect in the filtering tank 13. When collecting treatment is performed on the solid dirt, the conduction of the collecting air duct 61 is controlled by the second control valve, and therefore the collecting air duct 61 is in communication with the filtering tank 13. In this case, the solid dirt in the filtering tank 13 can enter the collecting air duct 61 through the filtering tank 13. Meanwhile, the blocking of the drying air duct 51 may also be controlled by the first control valve, and therefore the filtering tank 13 and the drying air duct 51 are cut off. Thus, a negative-pressure state at the filtering tank 13 due to the communication between the filtering tank 13 and the drying air duct 51 can be better avoided. In addition, when the cleaning base station 100 washes the mopping member 200 and the washing tank 111, the drying air duct 51 may be blocked by the first control valve, and simultaneously the collecting air duct 61 may be blocked by the second control valve, to prevent moisture in the washing tank 111 and the filtering tank 13 from entering the drying air duct 51 or the collecting air duct 61 through the filtering tank 13.

[0136] In some embodiments, the first control valve is located adjacent to an outlet end of the drying air duct 51. The outlet end of the drying air duct 51 is in communication with the filtering tank 13, that is, the first control valve is located adjacent to an end of the drying air duct 51 in communication with the filtering tank 13. Thus, the first control valve can block the drying air duct 51 at the position adjacent to the outlet end of the drying air duct 51. Therefore, a region between a part of the drying air duct 51 and a part of the filtering tank 13 in communication with the part of the drying air duct 51 when the drying air duct 51 is blocked can be better reduced. In this way, it is beneficial to further reduce the impact of the drying air duct 51 on the air flow in the collecting assembly. In addition, the first control valve may prevent the moisture from entering the drying air duct 51 to ensure that the drying air duct 51 is in a dry environment.

[0137] In some embodiments, the second control valve is located adjacent to an inlet end of the collecting air duct 61. The inlet end of the collecting air duct 61 is in communication with the filtering tank 13, that is, the second control valve is located adjacent to an end of the collecting air duct 61 in communication with the filtering tank 13. Thus, the second control valve can block the collecting air duct 61 at the position adjacent to the inlet end of the collecting air duct 61. Therefore, a region between a part of the collecting air duct 61 and a part of the filtering tank 13 in communication with the part of the collecting air duct 61 when the collecting air duct 61 is blocked can be reduced. In this way, it is beneficial to further reduce the impact of the collecting air duct 61 on the air flow in the drying air duct 51. In addition, the second control valve may prevent the moisture from entering the collecting air duct 61 to ensure that the collecting air duct 61 is in a dry environment.

[0138] In some embodiments, the first control valve and the second control valve may be integrated into one control valve. Conduction and blocking of the drying air duct 51 and / or conduction and blocking of the collecting air duct 61 may be controlled by the control valve.

[0139] In a specific example, the first control valve is located adjacent to an outlet end of the drying air duct 51, and the second control valve is located adjacent to an inlet end of the collecting air duct 61.

[0140] According to some embodiments of the present disclosure, the drying and collecting assembly comprises a drying assembly and a collecting assembly. The drying assembly comprises a drying air duct member 5, a drying fan, and a heating element. The drying air duct member 5 has the drying air duct 51. The heating element is disposed in the drying air duct 51. The drying fan is configured to deliver the heated air flow in the drying air duct 51 at least into the filtering tank 13. That is, an air flow passage that brings the filtering tank 13 into communication with the drying air duct 51 may be formed between the filtering tank 13 and the drying air duct 51. A temperature of gas in the drying air duct 51 can be better increased by the heating element, and hot air in the drying air duct 51 can be better driven to blow into the filtering tank 13 by the drying fan. Therefore, the moisture in the filtering tank 13 is evaporated by hot air entering the filtering tank 13. Thus, the drying treatment of the solid dirt in the filtering tank 13 and the filtering tank 13 is realized.

[0141] The collecting assembly comprises a collecting air duct member 6, a collecting fan, and a dust collecting component. The dust collecting component has a dust collecting chamber. The collecting air duct member 6 has the collecting air duct 61 adapted to bring the filtering tank 13 into communication with the dust collecting chamber. The collecting fan is configured to suck the solid dirt in the filtering tank 13 into the dust collecting chamber through the collecting air duct 61. That is, the filtering tank 13 forms an air flow passage in communication with the dust collecting chamber through the collecting air duct 61. The collecting fan may drive the gas in the filtering tank 13 to flow towards the dust collecting chamber through the collecting air duct member 6, and therefore the collecting assembly can form a negative pressure at the filtering tank 13, and the dried solid dirt in the filtering tank 13 can be stored in the dust collecting chamber through the collecting air duct member 6 along with the air flow. Thus, the collecting treatment of the solid dirt in the filtering tank 13 is realized by the collecting assembly. In addition, during operation of the drying assembly, the hot air entering the filtering tank 13 can further escape into the washing tank 111. Therefore, the drying treatment can be performed on the mopping member 200 that has been washed in the washing tank 111 through the hot air generated by the drying assembly. Thus, drying of the mopping member 200 can be better ensured to prevent the mopping member 200 from being damp and generating odor or breeding bacteria. In a specific example, the dust collecting component is detachably disposed in the cleaning base station 100 to facilitate the user to clean and dump dirt collected in the dust collecting chamber. In this way, it is beneficial to improving the user experience.

[0142] According to some embodiments of the present disclosure, the drying and collecting assembly comprises a drying assembly and a collecting assembly. That is, the drying assembly is configured to dry solid dirt in the filtering tank 13, and the collecting assembly is configured to collect dried solid dirt in the filtering tank 13. Therefore, accumulation of wet solid dirt in the filtering tank 13 can be better avoided while better preventing the collecting assembly from sucking in the wet solid dirt, which would otherwise result in growth of mud or bacteria inside the collecting assembly. In this way, it is beneficial to improving the cleanliness of the internal environment of the collecting assembly and better improve a self-cleaning ability of the cleaning base station 100. As a result, the cleaning base station 100 has a high level of automation.

[0143] The drying assembly comprises a drying fan and a heating element. The heating element is configured to heat air flow, and the drying fan is configured to deliver heated air flow at least into the filtering tank 13. That is, an air flow passage that brings the filtering tank 13 into communication with the drying air duct 51 may be formed between the filtering tank 13 and the drying air duct 51. A temperature of gas in the drying air duct 51 can be better increased by the heating element, and hot air in the drying air duct 51 can be better driven to blow into the filtering tank 13 by the drying fan. Therefore, the moisture in the filtering tank 13 is evaporated by hot air entering the filtering tank 13. Thus, the drying treatment of the solid dirt in the filtering tank 13 and the filtering tank 13 is realized. In addition, during operation of the drying assembly, the hot air entering the filtering tank 13 can further escape into the washing tank 111. Therefore, the drying treatment can be performed on the mopping member 200 that has been washed in the washing tank 111 through the hot air generated by the drying assembly. Thus, drying of the mopping member 200 can be better ensured to prevent the mopping member 200 from being damp and generating odor or breeding bacteria. In a specific example, the dust collecting component is detachably disposed in the cleaning base station 100 to facilitate the user to clean and dump dirt collected in the dust collecting chamber. In this way, it is beneficial to improving the user experience.

[0144] Further, the collecting assembly comprises the collecting air duct member 6, the collecting fan, and the dust collecting component. The dust collecting component has a dust collecting chamber. The collecting air duct member 6 has the collecting air duct 61 adapted to bring the filtering tank 13 into communication with the dust collecting chamber. The collecting fan is configured to suck the solid dirt in the filtering tank 13 into the dust collecting chamber through the collecting air duct 61. That is, the filtering tank 13 forms an air flow passage in communication with the dust collecting chamber through the collecting air duct 61. The collecting fan may drive the gas in the filtering tank 13 to flow towards the dust collecting chamber through the collecting air duct member 6, and therefore a negative pressure can be formed at the filtering tank 13. As a result, the dried solid dirt in the filtering tank 13 can be stored in the dust collecting chamber through the collecting air duct member 6 along with the air flow. Thus, the collecting treatment of the solid dirt in the filtering tank 13 is realized. In a specific example, the dust collecting component is detachably disposed in the cleaning base station 100 to facilitate the user to clean dirt collected in the dust collecting chamber. In this way, it is beneficial to improving the user experience.

[0145] According to some embodiments of the present disclosure, the drying and collecting assembly further comprises the suction nozzle 7 located in the filtering tank 13 and connected to an inlet end of the collecting air duct member 6. That is, the suction nozzle 7 is close to the filtering tank 13 and in communication with the collecting air duct 61, and therefore the solid dirt in the filtering tank 13 can enter the dust collecting chamber through the suction nozzle 7 and the collecting air duct member 6 sequentially under driving of the collecting fan. The distance between the suction nozzle 7 and the solid dirt in the filtering tank 13 can be better shortened by providing the suction nozzle 7 in the filtering tank 13. Therefore, the suction force of the drying and collecting assembly exerted on the solid dirt in the filtering tank 13 can be better improved. Thus, the collection effect of the collecting assembly on the solid dirt in the filtering tank 13 can be better improved. In this way, it is beneficial to improving the cleanliness in the filtering tank 13.

[0146] According to some embodiments of the present disclosure, the drying and collecting assembly comprises the collecting air duct member 6, the drying air duct member 5, and the suction nozzle 7. The collecting air duct member 6 has the collecting air duct 61. The drying air duct member 5 has the drying air duct 51. The suction nozzle 7 is located in the filtering tank 13, and an outlet end of the drying air duct member 5 is connected to an inlet end of the collecting air duct member 6 by the suction nozzle 7. The suction nozzle 7 is in selective communication with one of the drying air duct 51 and the collecting air duct 61. That is, it may be that the filtering tank 13 is controlled to be in communication with the drying air duct 51, and therefore the hot air generated by the drying assembly can be delivered to the filtering tank 13 through the drying air duct 51 to realize the drying treatment of the solid dirt in the filtering tank 13. Also, it may be that the filtering tank 13 is controlled to be in communication with the collecting air duct 61, and therefore the collecting assembly can collect the solid dirt in the filtering tank 13 through the collecting air duct 61. Thus, the mutual interference between drying air flow and collecting the air flow can be avoided to ensure the stability of the drying process and the collecting process.

[0147] According to some embodiments of the present disclosure, the drying and collecting assembly further comprise an air duct connector 8. Each of the collecting air duct member 6 and the drying air duct member 5 is connected to an end of the air duct connector 8. The suction nozzle 7 is connected to another end of the air duct connector 8. The air duct connector 8 has a first passage 81 adapted to bring the drying air duct 51 into communication with the suction nozzle 7 and a second passage 82 adapted to bring the collecting air duct 61 into communication with the suction nozzle 7. That is, the suction nozzle 7 is in communication with the collecting air duct member 6 and the drying air duct member 5 through the air duct connector 8, and an air flow passage that brings the drying air duct 51 into communication with the filtering tank 13 is formed between the drying air duct 51 and the filtering tank 13 through the first passage 81 and the suction nozzle 7. Therefore, the drying fan may drive the hot air in the drying air duct 51 to be delivered to the filtering tank 13 through the first passage 81 and the suction nozzle 7, to perform the drying treatment on the solid dirt in the filtering tank 13 by means of the hot air. An air flow passage that brings the dust collecting chamber into the filtering tank 13 may be formed between the dust collecting chamber and the filtering tank 13 through the collecting air duct 61, the second passage 82, and the suction nozzle 7, and therefore under the driving of the collecting fan, the solid dirt in the filtering tank 13 can enter the dust collecting chamber through the suction nozzle 7, the second passage 82, and the collecting air duct 61 sequentially, to realize the dust collecting treatment of the solid dirt in the filtering tank 13.

[0148] According to some embodiments of the present disclosure, the air duct connector 8 has a slide chamber 83, the suction nozzle 7 comprises a suction portion 71 and a slide portion 72. The suction portion 71 is formed with a suction inlet 711 and is located in the filtering tank 13, and the slide portion 72 is slidably disposed in the slide chamber 83 and has a communication chamber 723. The suction inlet 711 is in communication with each of the first passage 81 and the second passage 82 through the communication chamber 723. That is, the suction nozzle 7 is slidable relative to the air duct connector 8 by sliding the slide portion 72 relative to the slide chamber 83. Therefore, the suction nozzle 7 can be better controlled to slide relative to the filtering tank 13. Thus, a position of a suction portion 71 in the filtering tank 13 can be adjusted by sliding the suction nozzle 7 relative to the filtering tank 13. Meanwhile, during the sliding of the suction nozzle 7 relative to the filtering tank 13, the connection between the suction nozzle 7 and the air duct connector 8 can be better ensured through the engagement between the slide portion 72 and the slide chamber 83. The first passage 81 is in communication with the second passage 82 through the slide chamber 83, and therefore through the communication between the communication chamber 723 and the slide chamber 83, the communication between the suction inlet 711 and the first passage 81 as well as the communication between the suction inlet 711 and the second passage 82 can be ensured during the sliding of the suction portion 71 relative to the filtering tank 13. That is, while ensuring that the suction nozzle 7 is slidable relative to the filtering tank 13, the communication between the filtering tank 13 and the drying air duct 51 or the communication between the filtering tank 13 and the collecting air duct 61 is ensured. In this way, it is beneficial to improving reliability of the drying and collecting assembly.

[0149] In an exemplary embodiment of the present disclosure, the drying air duct 51 into communication with the filtering tank 13 through an air flow passage formed by the drying air duct 51 and the filtering tank 13 through the first passage 81, the slide chamber 83, the communication chamber 723, and the suction inlet 711. Therefore, the drying fan can drive the hot air in the drying air duct 51 to be delivered to the filtering tank 13 through the first passage 81, the slide chamber 83, the communication chamber 723, and the suction inlet 711, to perform the drying treatment on the solid dirt in the filtering tank 13 by means of the hot air. The dust collecting chamber into communication with the filtering tank 13 through an air flow passage that may be formed by the dust collecting chamber and the filtering tank 13 through the collecting air duct 61, the second passage 82, the slide chamber 83, the communication chamber 723, and the suction inlet 711, and therefore the solid dirt in the filtering tank 13 can enter, under the driving of the collecting fan, the dust collecting chamber through the suction inlet 711, the communication chamber 723, the slide chamber 83, the second passage 82, and the collecting air duct 61 sequentially, to realize the dust collecting treatment of the solid dirt in the filtering tank 13. Thus, during the collecting of the solid dirt in the filtering tank 13, the collecting assembly can collect the solid dirt at the different positions in the filtering tank 13 through the suction nozzle 7. In this way, it is beneficial to improving the collection effect of the collecting assembly on the solid dirt in the filtering tank 13 through the suction nozzle 7. In addition, during the drying of the solid dirt in the filtering tank 13 or the drying of the filtering tank 13, the drying assembly can deliver the hot air to the different positions in the filtering tank 13 through the suction nozzle 7 by sliding the suction nozzle 7 relative to the filtering tank 13. In this way, it is beneficial to improving the drying effect of the drying assembly on the filtering tank 13 and the solid dirt in the filtering tank 13.

[0150] According to some embodiments of the present disclosure, the slide chamber 83 comprises a first slide chamber 831 and a second slide chamber 832 that are spaced apart from each other, the slide portion 72 comprises a first slide portion 721 and a second slide portion 722 that are spaced apart from each other. Each of the first slide portion 721 and the second slide portion 722 is connected to the suction nozzle 7. The first slide portion 721 is slidably disposed in the first slide chamber 831, and the second slide portion 722 is slidably disposed in the second slide chamber 832. The first slide portion 721 internally has a first communication passage 7231, and the second slide portion 722 internally has a second communication passage 7232. The communication chamber 723 comprises the first communication passage 7231 and the second communication passage 7232. The suction inlet 711 is in communication with the first passage 81 through the first communication passage 7231, and the suction inlet 711 is in communication with the second passage 82 through the second communication passage 7232.

[0151] That is, during sliding of the suction nozzle 7 relative to the filtering tank 13, the connection between the suction nozzle 7 and the air duct connector 8 can be better ensured through the engagement between the first slide portion 721 and the first slide chamber 831 as well as the engagement between the second slide portion 722 and the second slide chamber 832. The first slide chamber 831 is in communication with the first passage 81, and therefore the communication between the suction inlet 711 and the first passage 81 can be better ensured through the first communication passage 7231 and the first slide chamber 831. The second slide chamber 832 is in communication with the second passage 82, and therefore the communication between the suction inlet 711 and the second passage 82 can be better ensured through the second communication passage 7232 and the second slide chamber 832. Meanwhile, a sliding direction of the first slide portion 721 can be better limited by the first slide chamber 831, and the sliding direction of the second slide portion 722 can be better limited by the second slide chamber 832. Thus, sliding stability of the suction nozzle 7 relative to the air duct connector 8 can be better improved.

[0152] In a specific example, the drying air duct member 5, the collecting air duct member 6, and the air duct connector 8 are integrally formed. The integrally formed structure can not only ensure structural and performance stability of the drying air duct member 5, the collecting air duct member 6, and the air duct connector 8, but also facilitate molding and simple manufacturing, and furthermore, eliminate assembling components and connection operations among the drying air duct member 5, the collecting air duct member 6, and the air duct connector 8. In this way, production cost is low, assembling efficiency of the drying air duct member 5, the collecting air duct member 6, and the air duct connector 8 is greatly improved, and connection reliability of the drying air duct member 5, the collecting air duct member 6, and the air duct connector 8 is ensured. Therefore, sealing of the communication between the first passage 81 and the drying air duct 51 can be better ensured. Meanwhile, sealing of the communication between the second passage 82 and the collecting air duct 61 can also be better ensured. Moreover, the integrally formed structure has high overall strength and stability and a longer service life.

[0153] According to some embodiments of the present disclosure, the first communication passage 7231 is in communication with the second communication passage 7232 through the slide chamber 83. Thus, when the hot air is delivered to the filtering tank 13, the drying air duct 51 may be in communication with the first communication passage 7231 and the second communication passage 7232 through the slide chamber 83, and the hot air is finally delivered to the filtering tank 13 through the suction inlet 711 to dry the solid dirt. During the collecting of the solid dirt in the filtering tank 13, the collecting air duct 61 may be in communication with the first communication passage 7231 and the second communication passage 7232 through the slide chamber 83, and thus the solid dirt in the filtering tank 13 can be collected through the first communication passage 7231 and the second communication passage 7232 separately. Thus, an air output volume of the drying air duct 51 to the filtering tank 13 can be better increased, and the collection effect of the collecting air duct 61 on the solid dirt in the filtering tank 13 can be improved.

[0154] In a specific example, during operation of the drying fan, the first communication passage 7231 is in communication with the second communication passage 7232 through the slide chamber 83. That is, during the operation of the drying fan, the first passage 81 is in communication with the drying air duct 51, and therefore the slide chamber 83 is in communication with the first passage 81, allowing each of the first communication passage 7231 and the second communication passage 7232 to be in communication with the drying air duct 51 through the slide chamber 83 and the first passage 81. As a result, the hot air in the drying air duct 51 can enter the first communication passage 7231 and the second communication passage 7232 separately under the driving of the drying fan, and finally be delivered to the filtering tank 13 through the suction inlet 711 to dry the solid dirt. Therefore, an air output volume discharged into the filtering tank 13 can be better increased during the operation of the drying fan, and an air output area at the suction inlet 711 can be better increased to improve the drying effect of the drying assembly on the filtering tank 13 through the suction nozzle 7.

[0155] According to some optional embodiments of the present disclosure, the cleaning base station 100 further comprises a drainage assembly configured to discharge sewage in the filtering tank 13. The drainage assembly comprises a sewage discharge tube 4. The base 1 further has the sewage buffer chamber 14 located below the filtering tank 13 and in communication with the filtering tank 13 through the filtering structure. The sewage discharge tube 4 is connected to the bottom wall of the filtering tank 13 and in communication with the sewage buffer chamber 14. The sewage discharge tube 4 is configured to discharge sewage in the sewage buffer chamber 14 and located between the drying air duct member 5 and the collecting air duct member 6. Thus, the sewage in the sewage buffer chamber 14 can be discharged in time through the sewage discharge tube 4. Therefore, the sewage buffer chamber 14 can continuously receive sewage flowing into the filtering tank 13 from the washing tank 111, which may avoid the sewage in the washing tank 111 from exceeding an upper limit of a capacity of the washing tank 111 and overflowing the base 1. Meanwhile, the sewage discharge tube 4 can fully utilize a mounting space between the drying air duct member 5 and the collecting air duct member 6. As a result, the structure of the cleaning base station 100 is compact.

[0156] In an exemplary embodiment of the present disclosure, after the dirt in the washing tank 111 enters the washing tank 111, the sewage flows downwards into the sewage buffer chamber 14 through the filtering structure, and the solid dirt is blocked on the filtering structure. The sewage in the sewage buffer chamber 14 is continuously discharged through the sewage discharge tube 4 to prevent the sewage from overflowing. After the sewage in the sewage buffer chamber 14 is discharged, the filtering tank 13 and the solid dirt in the filtering tank 13 can be dried by the drying assembly. After the drying of the solid dirt is completed, the solid dirt on the filtering tank 13 is sucked into the dust collecting chamber of the dust collecting component for storage by the collecting assembly.

[0157] According to some embodiments of the present disclosure, the cleaning base station comprises a collecting assembly disposed at the base 1 and configured to collect the solid dirt in the filtering tank 13. That is, the solid dirt in the filtering tank 13 may be discharged from the filtering tank 13 and collected centrally by the collecting assembly. Thus, the solid dirt can be prevented from accumulating in the filtering tank 13, which would otherwise block the filtering structure or lead to the growth of mud or bacteria, and meanwhile affect the flowing of the dirt in the washing tank 111 into the filtering tank 13. In this way, it is beneficial to improving the cleanliness of the filtering tank 13. Further, the collecting assembly comprises the suction nozzle 7 movably located in the filtering tank 13, and the solid dirt in the filtering tank 13 is adapted to be sucked into the collecting assembly through the suction nozzle 7. That is, the suction nozzle 7 is movable relative to the filtering tank 13. Therefore, the position of the suction nozzle 7 in the filtering tank 13 can be adjusted by driving the suction nozzle 7 to move. Thus, the collecting assembly can collect solid dirt located at different positions in the filtering tank 13 through the suction nozzle 7. In addition, the distance between the suction nozzle 7 and the solid dirt in the filtering tank 13 can be better shortened by providing the suction nozzle 7 in the filtering tank 13. Thus, the suction force of the collecting assembly exerted on the solid dirt in the filtering tank 13 can be improved. As a result, the collection effect of the collecting assembly on the solid dirt in the filtering tank 13 can be improved. In this way, it is beneficial to improving the cleanliness of the filtering tank 13.

[0158] According to some embodiments of the present disclosure, the cleaning base station 100 further comprises a drainage assembly configured to discharge sewage generated in the washing tank 111. The drainage assembly may be a drainage tube, and two ends of the drainage tube are respectively in communication with the washing tank 111 and a sewer pipe such as a sewer. As a result, the sewage in the washing tank 111 can be directly discharged into the sewer pipe through the drainage tube. The drainage assembly may also be a sewage box 10b disposed at the cleaning base station 100, and the sewage box 10b may be in communication with the washing tank 111 through the sewage discharge tube 4. The sewage in the washing tank 111 may flow into the sewage box 10b, and the user may manually clean the sewage in the sewage box 10b. The drainage assembly may also comprise the sewage box 10b and a water discharge tube. Two ends of the water discharge tube are respectively in communication with the sewage box 10b and the sewer pipe such as the sewer, and the sewage box 10b may be in communication with the washing tank 111 through the sewage discharge tube 4. As a result, sewage in the sewage box 10b can be automatically discharged into the sewer through the water discharge tube.

[0159] In a specific example, the cleaning base station 100 comprises a water supply assembly configured to supply water to the washing tank 111 and a drainage assembly configured to discharge sewage generated in the washing tank 111. The water supply assembly and the drainage assembly are constructed as a water supply and drainage module.

[0160] In a specific example, the drainage assembly comprises the sewage discharge tube 4, and the base 1 further has the sewage buffer chamber 14 located below the filtering tank 13 and in communication with the filtering tank 13 through the filtering structure. The sewage discharge tube 4 is connected to the bottom wall of the filtering tank 13 and in communication with the sewage buffer chamber 14. That is, in the filtering tank 13, sewage flowing downwards through the filtering structure may flow into the sewage buffer chamber 14 for temporary storage. Meanwhile, the filtering structure may prevent the solid dirt such as the solid particles and the hair from entering the sewage buffer chamber 14, which would otherwise be difficult to clean. The solid dirt is accumulated in the filtering structure located at the sewage buffer chamber 14, which may reduce the difficulty in cleaning the solid dirt on the filtering structure.

[0161] The sewage discharge tube 4 is configured to discharge sewage in the sewage buffer chamber 14, and the sewage discharge tube 4 is located between the drying air duct member 5 and the collecting air duct member 6. Thus, the sewage in the sewage buffer chamber 14 can be discharged in time through the sewage discharge tube 4. Therefore, the sewage buffer chamber 14 can continuously receive the sewage flowing into the filtering tank 13 from the washing tank 111, which may avoid the sewage in the washing tank 111 from exceeding the upper limit of the capacity of the washing tank 111 and overflowing the base 1, to avoid the dirt from polluting the space where the cleaning base station 100 is located. The sewage discharge tube 4 is located between the drying air duct member 5 and the collecting air duct member 6. Thus, the sewage discharge tube 4 can fully utilize the mounting space between the drying air duct member 5 and the collecting air duct member 6. As a result, the structure of the cleaning base station 100 is compact. Further, the air duct connector 8 has an avoidance hole 84 configured to avoid the sewage discharge tube 4 and located between the first slide chamber 831 and the second slide chamber 832. Thus, the sewage discharge tube 4 extends through the air duct connector 8 through the avoidance hole 84. A part of the sewage discharge tube 4 extending through the connecting air duct component 8 can fully utilize a space between the first slide chamber 831 and the second slide chamber 832, and a part of the sewage discharge tube 4 extending out of the air duct connector 8 is located between the drying air duct member 5 and the collecting air duct member 6. As a result, the overall structure of the drying and collecting assembly is compact. Meanwhile, the sewage discharge tube 4 can be better prevented from interfering with the sliding of the first slide portion 721 in the first slide chamber 831 and the second slide portion 722 in the second slide chamber 832, which is beneficial to improving stability of the suction nozzle 7 sliding relative to the air duct connector 8.

[0162] According to some optional embodiments of the present disclosure, the cleaning base station 100 further comprises a drainage assembly configured to discharge sewage in the filtering tank 13. The drainage assembly comprises the sewage discharge tube 4. The base 1 further has the sewage buffer chamber 14. The filtering tank 13 is formed with the filtering structure at the bottom wall of the filtering tank 13. The sewage buffer chamber 14 is located below the filtering tank 13 and in communication with the filtering tank 13 through the filtering structure. The sewage discharge tube 4 is connected to the bottom wall of the filtering tank 13 and in communication with the sewage buffer chamber 14. The sewage discharge tube 4 is configured to discharge sewage in the sewage buffer chamber 14 and located between the drying air duct member 5 and the collecting air duct member 6. Thus, the sewage in the sewage buffer chamber 14 can be discharged in time through the sewage discharge tube 4. Therefore, the sewage buffer chamber 14 can continuously receive sewage flowing into the filtering tank 13 from the washing tank 111, which may avoid the sewage in the washing tank 111 from exceeding the upper limit of the capacity of the washing tank 111 and overflowing the base 1. Meanwhile, the sewage discharge tube 4 can fully utilize the mounting space between the drying air duct member 5 and the collecting air duct member 6. As a result, the structure of the cleaning base station 100 is compact.

[0163] In an exemplary embodiment of the present disclosure, after the dirt in the washing tank 111 enters the washing tank 111, the sewage flows downwards into the sewage buffer chamber 14 through the filtering structure, and the solid dirt is blocked on the filtering structure. The sewage in the sewage buffer chamber 14 is continuously discharged through the sewage discharge tube 4 to prevent the sewage from overflowing. After the sewage in the sewage buffer chamber 14 is discharged, the filtering tank 13 and the solid dirt in the filtering tank 13 can be dried by the drying assembly. After the drying of the solid dirt is completed, the solid dirt on the filtering tank 13 is sucked into the dust collecting chamber of the dust collecting component for the storage by the collecting assembly.

[0164] According to some embodiments of the present disclosure, the drainage assembly further comprises the sewage box 10b which is in communication with the sewage buffer chamber 14 through the sewage discharge tube 4. That is, the sewage in the sewage buffer chamber 14 may flow into the sewage box 10b through the sewage discharge tube 4. That is, the sewage generated during the operation of the cleaning base station 100 is temporarily stored through the sewage box 10b. As a result, the user can clean the sewage box 10b according to an amount of sewage stored in the sewage box 10b. Therefore, the cleaning base station 100 can simultaneously realize functions of cleaning the mopping member 200, self-cleaning, and sewage recycling. In this way, the automation level of the cleaning base station 100 can be better reduced to reduce the user's operation, and thus to facilitate improving the user experience. In some other embodiments, a water outlet end of the sewage discharge tube 4 may be in direct communication with the sewer, allowing the sewage generated in the cleaning base station 100 to be directly discharged into the sewer through the sewage discharge tube 4. In this way, it is beneficial to simplify the structure of the cleaning base station 100.

[0165] In addition, the connection between the sewage discharge tube 4 and the bottom wall of the filtering tank 13 is located above the sewage buffer chamber 14. Therefore, difficulty of inspection and maintenance of the sewage discharge tube 4 can be better reduced. In a specific example, the filtering tank 13 is provided with a connecting branch pipe 122 at the bottom wall of the filtering tank 13. The connecting branch pipe 122 extends obliquely backwards from bottom to top. A lower end of the connecting branch pipe 122 is formed into a sewage outlet that faces towards and is in communication with the sewage buffer chamber 14. The sewage discharge tube 4 is arranged around an upper end of the connecting branch pipe 122.

[0166] According to some embodiments of the present disclosure, the filtering assembly comprises a filter 19 disposed in the washing tank 111. The filter 19 has a storage tank 191 and the dust opening 192, and the storage tank 191 is in communication with the washing tank 111 through the dust opening 192. Therefore, the washing member 2 is movably disposed in the washing tank 111. After the sewage in the washing tank 111 enters the filtering tank 13 through a movement of the washing member 2, it may further enter the storage tank 191 through the dust opening 192 for temporary storage to prevent the dirt from accumulating in the washing tank 111.

[0167] According to some embodiments of the present disclosure, the washing member 2 comprises the fixing seat 26, the support body 27, and the support arm 28. The fixing seat 26 is fixedly disposed at the bottom surface of the washing tank 111. Exemplarily, the fixing seat 26 is formed with a first mounting hole 26a, and the washing tank 111 is formed with a second mounting hole 1a2 at the bottom surface of the washing tank 111. The fixing seat 26 can be fixed at the bottom surface of the washing tank 111 by fasteners such as screws or studs to pass through the first mounting hole 26a and the second mounting hole 1a2 to provide stable support.

[0168] The support body 27 is rotatably connected to the fixing seat 26. The support arm 28 is disposed at a circumferential surface of the support body 27. The washing surface 2a is formed at an upper surface of the support arm 28, and the sweeping surface 2b is formed at a lower surface of the support arm 28. The dust opening 124 is within a range of a travel trajectory formed during rotation of the support arm 28. In this way, during the rotation of the support arm 28, substances on the washing tank 111 can be swept into the storage tank 191 through the dust opening 124, which is convenient to clean and sweep with easy storage of the substances.

[0169] An appearance shape of the mopping member 200 is not limited. Exemplarily, the mopping member 200 may be of a circular shape substantially.

[0170] According to some embodiments of the present disclosure, taking a plane perpendicular to the up-down direction as a projection surface, a projection area of the washing tank 111 is greater than or equal to a total projection area of the mopping member 200. Exemplarily, a shape of the washing tank 111 is not limited. For example, the washing tank 111 may be constructed by fitting two quasi-circular grooves together, and each of the quasi-circular grooves has a diameter between 10 mm and 30 mm larger than a diameter of the mopping member 200. In this way, the entire mopping member 200 can be fully washed to avoid the garbage and the sewage flowing out and falling outside the washing tank 111 after cleaning the mopping member 200. As a result, the user experience is good.

[0171] According to some embodiments of the present disclosure, the washing member 2 is rotatably disposed in the washing tank 111. In this way, it is convenient for the washing member 2 to be in full contact with the mopping member 200, and the mopping member 200 and the bottom surface of the washing tank 111 can be cleaned more efficiently. As a result, efficiency is high.

[0172] Exemplarily, according to some embodiments of the present disclosure, a drive device such as a motor is configured to drive the washing member 2 to rotate. In this way, controllability is high.

[0173] According to some embodiments of the present disclosure, the mopping member 200 drives the washing member 2 to rotate. In this way, the washing member 2 is driven to rotate by using the rotation of the mopping member 200 to reduce additional driving cost of the driving device, which is highly cost-effective.

[0174] According to some embodiments of the present disclosure, the base 1 comprises the limiting member 3 disposed in the washing tank 111, and the washing member 2 is configured to avoid or abut with the limiting member 3 in a rotation direction of the washing member 2. Exemplarily, the limiting member 3 is formed with a limit surface protruding towards the washing tank 111 at a circumferential surface of the limiting member 3, and the washing member 2 is configured to abut with the limit surface during rotation of the washing member 2 to limit the rotation of the washing member 2. In this way, the washing member 2 may abut with the limiting member 3 when the washing member 2 rotates forwards and in reverse. As a result, the washing member 2 touches the limiting member 3 when rotating forwards or in reverse and thus cannot continue rotating in its previous rotation direction.

[0175] The washing member 2 is rotatable relative to the mopping member 200 in a state where the washing member 2 abuts with the limiting member 3, and the washing member 2 is rotatable relative to the bottom surface of the washing tank 111 in a state where the washing member 2 avoids the limiting member 3. That is, in the state where the washing member 2 abuts with the limiting member 3, the washing member 2 and the base 1 remain relatively stationary, and the mopping member 200 is rotatable relative to the washing member 2. In this way, the washing surface 2a can scrub the mopping member 200, and thus garbage on the mopping member is cleaned. In the state where the washing member 2 avoids the limiting member 3, the washing member 2 is in an active state, and the washing member 2 is rotatable relative to the bottom surface of the washing tank 111. In this way, the sweeping surface 2b can scrub the bottom surface of the washing tank 111, and thus garbage on the bottom surface of the washing tank 111 is cleaned into the filtering tank 13.

[0176] Exemplarily, in a specific embodiment, the limiting member 3 is formed with a forward rotation limit surface 3a and a reverse rotation limit surface 3b. After the washing member 2 rotates forwards and abuts with the forward rotation limit surface 3a, the washing member 2 cannot continue rotating forwards. Similarly, after the washing member 2 rotates in reverse and abuts with the reverse rotation limit surface 3b, the washing member 2 cannot continue rotating in reverse. The forward rotation is described as an example. When the mopping member drives the washing member 2 to rotate forwards together, the mopping member 200 and the washing member 2 rotate synchronously before the washing member 2 abuts with the forward rotation limit surface 3a. In this case, the sweeping surface 2b of the washing member 2 may wash and sweep the bottom surface of the washing tank 111 to sweep substances in the washing tank 111 into the filtering tank 13 through the dust opening 125, to avoid the substances from being exposed to the washing tank 111. In this way, the cleaning is facilitated, and the user experience is good. After the washing member 2 abuts with the forward rotation limit surface 3a, the washing member 2 cannot continue rotating forwards and stays at the forward rotation limit surface 3a. Since the mopping member 200 and the washing member 2 are only in contact rotation with each other, the mopping member 200 can continue rotating forwards after the washing member 2 stops rotating. Therefore, the mopping member 200 and the washing member 2 are rotatable relative to each other. In this case, the washing surface 2a of the washing member 2 can wash the mopping member 200 located above the washing member 2 to scrape large particles of garbage, small particles of garbage, and the sewage on the wiping part 200 into the washing tank 111. Further, the mopping member 200 rotates in reverse, and in this case, the washing member 2 leaves the forward rotation limit surface 3a and starts to rotate with the mopping member 200 in reverse. In this way, the large particles of garbage dropped into the washing tank 111 can be cleaned, and then the wiping part 200 repeats the above forward and reverse rotation actions to complete the repeated washing of the mopping member 200 and the treatment of the large particles of garbage.

[0177] According to some embodiments of the present disclosure, the filter 19 is detachably connected to the base 1. Exemplarily, the bottom surface of the washing tank 111 is partially sunken downwards to form a mounting groove 1a1 matching a shape of the filter 19. The filter 19 is formed with a buckle 19c at an end of the filter 19 away from the limiting member 3, and the mounting groove 1a1 is formed with a protruding post (not shown in the figures) at a side of the mounting groove 1a1 away from the limiting member 3. The buckle 19c is snapped with the protruding post to mount the filter 19 in the mounting groove 1a1. In this way, after the substances enter the storage tank 191, the user can manually disassemble the filter 19 to clean it, which facilitates the assembling and disassembling. In some embodiments, a depth of the mounting groove 1a1 is same as a thickness of the filter 19. In this way, the rotation of the washing member 2 is not restricted, and the structure is compact.

[0178] According to some embodiments of the present disclosure, the filter 19 is internally formed with a sewage passage 19a and a water filtering hole 19b, and the washing tank 111 is in communication with the sewage passage 19a through the water filtering hole 19b. In this way, the sewage and the small particles of garbage mixed in the sewage may be collected together in the sewage passage 19a through the water filtering hole 19b to facilitate subsequent unified treatment, while the large particles of garbage are temporarily stored in the washing tank 111 to avoid blocking the sewage passage 19a.

[0179] According to some embodiments of the present disclosure, the cleaning base station 100 comprises two washing members 2, and the filter 19 is located between the two washing members 2. Exemplarily, the two washing members 2 are respectively arranged at two sides of the filter 19 in a length direction of the washing tank 111. In this way, the two mopping members 200 of the cleaning device may be washed simultaneously. The sewage and the small particles of garbage after the washing by the mopping members 200 may enter the sewage passage 19a through the water filtering hole 19b from a middle, and the substances dropped from the two mopping members 200 may be swept into the filtering tank 13 from the dust opening 124 of the washing member 2 at each of the two sides, which has high cleaning efficiency.

[0180] According to some embodiments of the present disclosure, the cleaning base station 100 comprises a sewage nozzle 16. The sewage nozzle 16 comprises a water outlet 16a and a negative-pressure suction opening 16b in communication with the water outlet 16a. The negative pressure suction opening 16b is in communication with the sewage passage 19a. In this way, the sewage and the small particles of garbage in the sewage passage 19a may be sucked through the sewage nozzle 16. Exemplarily, the cleaning base station 100 comprises a water pump connected to the negative-pressure suction opening 16b to suck the sewage in the sewage passage 19a.

[0181] According to some embodiments of the present disclosure, the cleaning base station 100 is further provided with the sewage box 10b in communication with the water outlet 16a through a tube channel. In this way, the sewage and the small particles of garbage sucked by the sewage nozzle 16 are temporarily stored in the sewage box 10b through the tube channel to avoid their contact with air, which would otherwise affect air quality. As a result, the user experience is good, and it is also convenient for the user to uniformly treat the sewage.

[0182] According to some embodiments of the present disclosure, a plurality of storage tanks 191 are provided and arranged at two sides of the sewage passage 19a in the length direction of the washing tank 111. Exemplarily, the number of storage tanks 191 is not limited. For example, two storage tanks 191 may be provided and arranged at the two sides of the sewage passage 19a in the length direction of the washing tank 111 to ensure that the substances at the two sides can be swept to the storage tank 191 through the dust opening 192, and thus to avoid odor due to exposure of the substances to the washing tank 111. In this way, the user experience is good.

[0183] According to some embodiments of the present disclosure, the storage tank 191 has a drainage opening 191a formed at a wall surface of the storage tank 191, and the sewage passage 19a is in communication with the storage tank 191 through the drainage opening 191a. In this way, sewage retained in the storage tank 191 may flow into the sewage passage 19a through the drainage opening 191a to avoid odor caused by long time soaking of the substances in the sewage. In addition, it is difficult to dump the substances when there is sewage in the storage tank 191.

[0184] A maximum width of the drainage opening 191a is smaller than a maximum width of the water filtering hole 19b. In this way, the substances can only enter the storage tank 191 through the dust opening 192 and cannot enter the sewage passage 19a through the drainage opening 191a, which would otherwise cause blockage of the sewage nozzle 16. As a result, garbage classification and treatment are clear, and the efficiency is high.

[0185] For example, according to some embodiments of the present disclosure, a shape of the dust opening 192 is not limited. For example, the dust opening 192 may be of a square shape, a rectangular shape, a square shape, a round shape, or other irregular shapes, a size of the dust opening 192 is specifically determined based on the substances that are capable of being loaded into the dust opening 192.

[0186] For example, according to some embodiments of the present disclosure, a shape of the water filtering hole 19b is not limited. For example, the water filtering hole 19b may be of a square shape, a rectangular shape, a square shape, a round shape, or other irregular shapes, and a size of the water filtering hole 19b may be determined based on a size of the small particles of garbage to realize an effect of limiting filtration, and thus to avoid blockage of the sewage nozzle 16.

[0187] According to some embodiments of the present disclosure, the filter 19 comprises an upper cover 193 and a lower plate 194. The upper cover 193 is formed with the dust opening 192 and the water filtering hole 19b. The lower plate 194 is disposed below the upper cover 193, and the lower plate 194 and the upper cover 193 define the storage tank 191 and the sewage passage 19a. The upper cover 193 is detachably connected to the lower plate 194. Exemplarily, one of the upper cover 193 and the lower plate 194 is formed with a protruding block 1941, another one of the upper cover 193 and the lower plate 194 is formed with a slot 1931, and the protruding block 1941 is snapped into the slot 1931. For example, the lower plate 194 is formed with five protruding blocks 1941 arranged at an edge of the lower plate 194, and the upper cover 193 is formed with a slot 1931 at a side surface of the upper cover 193 close to the lower plate 194. Five slots 1931 may be provided and arranged at positions corresponding to the protruding blocks 1941. In this way, after the user takes out the filter 19, if the substances cannot be poured out from the dust opening 192 or when the storage tank 191 and the sewage passage 19a need cleaning, the filter 19 can be opened manually. In this way it is convenient for the user to clean an inside of the filter 19, and thus the cleaning efficiency is high.

[0188] According to some embodiments of the present disclosure, the cleaning base station 100 comprises a liquid-level detection device 17 disposed at the filter 19 and configured to detect a water level of the washing tank 111. Exemplarily, the liquid-level detection device 17 may be a float assembly 171. For example, the float assembly 171 comprises an upper float cover 171a, a magnet 171b, and a lower float cover 171c. The lower float cover 171c is mounted in the upper float cover 171a through the magnet 171b. The filter 19 is formed with an accommodation chamber 19d at a side of the filter 19 away from the buckle 19c. The accommodation chamber 19d is provided with a rotary shaft hole 19e at an inner wall of the accommodation chamber 19d. The upper float cover 171a is formed with two elastic arms 1711 at a side of the upper float cover 171a. Each of the two elastic arms 1711 is formed with a rotation protrusion 1712 extending towards the rotary shaft hole 19e. During a mounting of a float attachment, the two elastic arms 1711 may be pinched by hand to bring the two elastic arms 1711 to be elastically deformed, which allows the rotation protrusion 1712 to be snapped into the rotary shaft hole 19e. In this way, when detecting the liquid level, one side of the float assembly 171 is configured to detect a liquid level, and another side is rotatable with a rise and fall of the liquid level to detect a liquid level of the filtering tank 13 in real time.

[0189] It can be understood that the sewage nozzle 16 may be started when the liquid level reaches a predetermined level. In this way, the sewage can be cleaned to lower a liquid level of the washing tank 111. If the liquid level does not drop significantly after the sewage nozzle 16 is started, whether blockage has occurred may be determined by detecting each passage of the sewage nozzle 16 and the filter 19.

[0190] According to some embodiments of the present disclosure, a scraping rib 192a is provided at a peripheral side wall of the dust opening 192, and the scraping rib 192a extends from the peripheral side wall of the dust opening 192 to a middle region of the dust opening 192. The support arm 28 is provided with a first washing structure 213 at the lower surface of the support arm 28, and the lower surface of the first washing structure 213 is the sweeping surface 2b. In this way, when the sweeping surface 2b washes and sweeps the substances, the substances such as lint and other garbage on the first washing structure 213 can be scraped into the storage tank 191 by the scraping rib 192a to keep the first washing structure 213 clean and prevent the substances carried by the first washing structure 213 from causing secondary contamination in the washing tank 111.

[0191] According to some embodiments of the present disclosure, the base 1 comprises the base body 11 and an upper shell 18. The base body 11 comprises a disk 11a and a ramp plate 11b. The disk 11a is formed with the washing tank 111 at an upper surface of the disk 11a. One end of the ramp plate 11b is connected to the disk 11a, and another end of the ramp plate 11b that is opposite to the end of the ramp plate 11b connected to the disk 11a is configured to abut with the cleaning surface. In this way, the cleaning device can enter the washing tank 111 at the disk 11a from the ramp plate to complete the washing of the mopping member 200, which has a high degree of automation.

[0192] The upper shell 18 covers on the disk 11a to form a washing chamber 181. The washing tank 111 is located in the washing chamber 181, and the ramp plate 11b is located outside the washing chamber 181. In this way, by forming the washing chamber 181, the cleaning device can be protected to a certain extent while reducing a space occupied by the cleaning device. As a result, a space utilization is high.

[0193] According to some embodiments of the present disclosure, the washing chamber 181 is provided with a guide wheel 182 rotatably disposed at an inner wall surface of the washing chamber 181, and the guide wheel 182 is configured to guide a main body to a predetermined region in the washing chamber 181. In this way, on the one hand, the main body can be prevented from being in direct contact with the inner wall surface of the washing chamber 181, which avoids damage to the main body and improves service life of the main body. On the other hand, the main body can be guided to the predetermined region, for example, in the washing tank 111 to allow the mopping member 200 to be in contact with the washing surface 2a, which has the high degree of automation.

[0194] According to some embodiments of the present disclosure, the ramp plate 11b is formed with a guide member 11c at an upper surface of the ramp plate 11b, and the guide member 11c is configured to guide the main body to the predetermined region in the washing chamber 181. When the cleaning device climbs up the ramp plate 11b, the guide member 11c at the ramp plate 11b is limited between the two mopping members 200 of the main body. In this way, the main body can enter the predetermined region in a guiding direction of the guide member 11c to allow the mopping member 200 to be in contact with the washing surface 2a. As a result, the degree of automation is high.

[0195] According to some embodiments of the present disclosure, the ramp plate is provided with an anti-skid rib 11d at the upper surface of the ramp plate. Exemplarily, the anti-skid rib 11d, for example, may be an elongated anti-skid rib 11d with a predetermined curvature and may be in a bump shape. In other exemplary embodiments of the present disclosure, the anti-skid ribs 11d of various shapes may be mixed. For example, the guide member 11c is formed with the anti-skid rib 11d at each of two sides of the guide member 11c in a length direction of the washing tank 111. The anti-skid rib 11d at one of the two sides may be an elongated strip anti-skid rib 11d, and the anti-skid rib 11d at another one of the two sides may be an anti-skid rib 11d of a bump shape. In this way, the cleaning device can smoothly reach the predetermined region to avoid the cleaning device from sliding sideways at the ramp plate 11b.

[0196] According to some embodiments of the present disclosure, the cleaning base station 100 further comprises a water supply assembly configured to supply water to the washing tank 111. The water supply assembly may be a water supply tube, and two ends of the water supply tube are respectively in communication with the washing tank 111 and an external water source such as a tap water pipe, allowing the external water source to directly enter the washing tank 111 through the water supply tube. The water supply assembly may also be the water supply box 10a disposed in the cleaning base station 100, and the water supply box 10a is in communication with the washing tank 111. The user can manually feed water to the water supply box 10a, allowing the water in the water supply box 10a to flow into the washing tank 111. The water supply assembly may further comprise a water supply tube and the water supply box 10a, two ends of the water supply tube are respectively in communication with an external water source such as a tap water pipe and the water supply box 10a, and the water supply box 10a is in communication with the washing tank 111. In this way, automatic water feeding to the water supply box 10a from the external water source can be realized.

[0197] In a specific example, the washing member 2 has the water outlet channel 23 at an upper surface of the washing member 2. Water in the water supply assembly is adapted to flow into the water outlet channel 23, and water in the water outlet channel 23 is adapted to overflow into the washing tank 111. That is, a certain amount of water may be stored in the water outlet channel 23, and water may be fed to the water outlet channel 23 by the water supply assembly. Therefore, when the washing member 2 is in the first washing state, the mopping member 200 is pressed against the washing member 2 and can sweep across the water outlet channel 23 when rotating relative to the washing member 2. Thus, the mopping member 200 can be wetted by the water in the water outlet channel 23, and the dirt such as the dust on the mopping member 200 can be better absorbed and dissolved by the water, enabling the dirt on the mopping member 200 to be separated from the mopping member 200 together with the water. Moreover, the water supply assembly can continuously feed clean water into the water outlet channel 23, that is, the mopping member 200 can be repeatedly washed by dipping into the clean water in the water outlet channel 23. In this way, secondary pollution to the mopping member 200 caused by the sewage in the washing tank 111 can be better avoided. As a result, it is beneficial to improving the cleaning effect of the mopping member 200.

[0198] Further, the washing tank 111 is formed with a water supply hole 114 at an inner peripheral wall of the washing tank 111, and the water supply assembly is in communication with the water supply hole 114 through a water supply passage. At the first washing state, the water outlet channel 23 is located adjacent to the water supply hole 114, and the water supply hole 114 is adapted to supply water to the water outlet channel 23. That is, when the washing member 2 is in the first washing state, the water in the water supply assembly may enter the water outlet channel 23 through the water supply passage and the water supply hole 114. Therefore, it can be ensured that the mopping member 200 is continuously wetted with the clean water in the water outlet channel 23 during the washing of the mopping member 200 to improve the washing efficiency and the washing effect of the mopping member 200. When the washing member 2 is in the second washing state, the water in the water supply assembly may directly flow into the washing tank 111 through the water supply hole 114 to participate in the washing of the washing tank 111 to improve the washing effect of the washing member 2 on the washing tank 111. In addition, by providing the water supply hole 114 at the inner peripheral wall of the washing tank 111, the space in the washing tank 111 can be fully utilized, and meanwhile, the water supply passage can be hidden at an outer side of the inner peripheral wall of the washing tank 111, which has an ingenious and reasonable layout. The water supply assembly may be a water inlet tube directly connected to a tap at home, and therefore tap water can directly enter the cleaning base station 100 through the water inlet tube. The water supply assembly may also be the water supply box 10a disposed in the cleaning base station 100, and the water supply box 10a is in communication with the water supply hole 114. The form of the water supply assembly is not specifically limited herein.

[0199] In an exemplary embodiment of the present disclosure, clean water may be continuously fed into the water outlet channel 23 and the washing tank 111 when the clean water is contained in the water supply box 10a, and therefore the mopping member 200 can be wetted with the clean water. Meanwhile, the inner wall of the washing tank 111 can be flushed with the clean water under the driving of the washing member 2, which further facilitates improving the washing effect of the cleaning base station 100 on the mopping member 200 and the washing tank 111. Clean water may be stored in the water supply box 10a, and of course, clean water mixed with a detergent may also be fed to the water supply box 10a, and a disinfectant may also be fed to the water supply box 10a, etc., to improve a cleaning intensity of liquid in the water supply box 10a of the mopping member 200 and the washing tank 111, and thus to facilitate ensuring the cleanliness of the mopping member 200 and the cleanliness in the washing tank 111. The type of the liquid stored in the water supply box 10a is not specifically limited herein.

[0200] Furthermore, the washing member 2 is rotatably disposed in the washing tank 111 and has a rotation axis extending in the up-down direction. The washing member 2 is formed with a water supply tank 24 at a radial outer end surface of the washing member 2. The radial outer end surface of the washing member 2 refers to a side wall of the washing member 2 facing towards the inner peripheral wall of the washing tank 111 in a length direction of the washing member 2. The water supply tank 24 penetrates through a side wall of the water outlet channel 23. The water supply tank 24 extends through the side wall of the water outlet channel 23. At the first washing state, the water supply tank 24 faces towards the water supply hole 114. That is, when the washing member 2 is in the first washing state, the water supply tank 24 faces towards the water supply hole 114 in a radial direction of the washing tank 111, and therefore water flowing out of the water supply hole 114 can flow into the water outlet channel 23 through the water supply tank 24 to realize water feeding of the water supply box 10a to the water outlet channel 23. Thus, by providing the water supply tank 24, the washing member 2 can reduce difficulty in feeding water to the water outlet channel 23 through the water supply hole 114 while rotating relative to the washing tank 111. Moreover, the structure is simple.

[0201] According to some embodiments of the present disclosure, the base 1 further has the sewage buffer chamber 14 located below the filtering tank 13 and in communication with the filtering tank 13 through the filtering structure. That is, in the filtering tank 13, sewage flowing downwards through the filtering structure may flow into the sewage buffer chamber 14 for temporary storage. Meanwhile, the filtering structure may prevent the solid dirt such as the solid particles and the hair from entering the sewage buffer chamber 14, which would otherwise be difficult to clean. The solid dirt is accumulated in the filtering structure located at the sewage buffer chamber 14, which may reduce the difficulty in cleaning the solid dirt on the filtering structure. It should be noted that the sewage in the filtering tank 13 may also be directly discharged through the sewage discharge passage after passing through the filtering structure, and therefore a retention time period of the sewage in the cleaning base station 100. No specific restrictions are made herein on the discharge manner of the sewage.

A lower end of the connecting branch pipe 122 protrudes from a lower surface of the filtering component 12 and is spaced apart from a bottom wall of the sewage buffer chamber 14. The bottom wall of the sewage buffer chamber 14 extends obliquely downwards in a front-rear direction. An upper end of the connecting branch pipe 122 protrudes from an upper surface of the filtering component 12 and is connected to the sewage discharge tube 4. An end of the sewage discharge tube 4 away from the connecting branch pipe 122 is connected to the sewage box 10b.

[0206] In addition, the upper surface of the filtering component 12 is constructed as the bottom wall of the filtering tank 13, and a bottom wall of the filtering tank 13 is lower than the bottom wall of the washing tank 111. The filtering component 12 has a plurality of filtering holes 121 extending through the filtering component 12 in the up-down direction, and the plurality of filtering holes 121 together form the filtering structure at the bottom wall of the filtering tank 13.

The washing tank 111 is in communication with the filtering tank 13 through the communication notch 113, and a bottom wall of the communication notch 113 is flush with the bottom wall of the washing tank 111. A left end and a right end of a front side of the filtering tank 13 respectively extend into the two washing tanks 111. In a direction from the washing tank 111 towards the filtering tank 13, the bottom wall of the washing tank 111 extends obliquely downwards to form a flow guide surface.

[0207] The drying and collecting assembly comprises a drying assembly, a collecting assembly, the suction nozzle 7, and the air duct connector 8. The drying assembly comprises the drying air duct member 5, a heating element, and a drying fan. The drying air duct member 5 has the drying air duct 51, and the drying fan and the heating element are disposed in the drying air duct 51.

The collecting air duct 61 is provided with the second control valve adjacent to the inlet end of the collecting air duct 61. The second control valve is configured to control communication and blocking between the collecting air duct 61 and the second passage 82. In addition, the avoidance hole 84 is located between the first slide chamber 831 and the second slide chamber 832 and extends through the air duct connector 8 in the up-down direction. The avoidance hole 84 is located above the connecting branch pipe 122. The sewage discharge tube 4 is disposed in the avoidance hole 84 and extends obliquely upwards from front to rear.

[0209] Further, the suction nozzle 7 is constructed as the limiting member 3 and comprises a suction portion 71 and a slide portion 72. The suction portion 71 is disposed at a front end of the slide portion 72 and located in the filtering tank 13. The suction portion 71 has a suction inlet 711 extending obliquely downwards from rear to front. The suction inlet 711 is of a flat-mouthed shape extending in the left-right direction. An upper side wall of the suction inlet 711 is formed as the flow-guide wall 713 extending obliquely from rear to front. A lower side wall of the suction inlet 711 is formed as the scraping wall 712, and a front edge of the flow-guide wall 713 extends beyond a front edge of the scraping wall 712. A thickness of the scraping wall 712 gradually increases from front to rear, and a front edge of the scraping wall 712 abuts with the bottom wall of the filtering tank 13. The drive mechanism 9 is disposed at an outer peripheral side of the base body 11 and connected to the suction nozzle 7 to drive the suction nozzle 7 to reciprocate relative to the air duct connector 8 in the front-rear direction.

[0210] In further, the slide portion 72 has a communication chamber 723 in communication with the suction inlet 711 and comprises a first slide portion 721 and a second slide portion 722 that are arranged in the left-right direction.

[0211] A region swept by the washing member 2 when rotating relative to the washing tank 111 is formed as a washing region, and the suction nozzle 7 has the limiting position and the non-limiting position. When the suction nozzle 7 is in the limiting position, the suction portion 71 moves forwards relative to the air duct connector 8 until at least part of the suction portion 71 extends into the washing region, and the part of the suction portion 71 in the washing region is formed as the limit portion 31. The limit portion 31 is configured to block rotation of the washing member 2 to allow the washing member 2 to be in the first washing state, and an upper surface of the limit portion 31 is lower than or flush with an upper surface of the washing member 2. When the suction nozzle 7 is in the non-limiting position, the suction portion 71 moves backwards relative to the air duct connector 8 until the suction portion 71 is located at an outer peripheral side of the washing region to lift the restriction of the suction nozzle 7 on the washing member 2, allowing the washing member 2 to rotate relative to the washing tank 111. In this case, the washing member 2 is in the second washing state. In further, a buffer structure is provided in a region between a part of the washing member body 21 and a part of the suction nozzle 7 abutting with the part of the washing member body 21. Two opposite side walls of the washing member body 21 in a circumferential direction of the washing member 2 are respectively a first side wall 211 and a second side wall 212, and each of the first side wall 211 and the second side wall 212 is provided with a buffer layer.

[0212] Further, the washing member body 21 is formed with the water outlet channel 23 and the washing protrusion 25 at an upper surface of the washing member body 21, and the water outlet channel 23 and the washing protrusion 25 are arranged in a length direction of the washing member 2 and respectively located at two sides of the rotary shaft 22. The water outlet channel 23 comprises a first tank region 231 and a second tank region 232 that are arranged in the length direction of the washing member 2. The first tank region 231 is located between an inner peripheral wall of the washing tank 111 and the second tank region 232. In a circumferential direction of the washing tank 111, the first tank region 231 has a width greater than a width of the second tank region 232. The first tank region 231 is located at a side of the second tank region 232 away from the rotary shaft 22, and a bottom wall of the second tank region 232 is lower than a bottom wall of the first tank region 231. The cleaning device is provided with the mopping member 200 covering the second tank region 232. At least part of the first tank region 231 is located at an outer peripheral side of the mopping member 200. In further, the first tank region 231 is formed with a water supply tank 24 at a radial outer wall of the first tank region 231, the washing tank 111 has a water supply hole 114 formed at an inner peripheral wall of the washing tank 111. The water supply box 10a is in communication with a water inlet end of the water supply hole 114 through a water supply passage, and the water supply hole 114 is located adjacent to the filtering tank 13. When the washing member 2 is in the first washing state, the water supply hole 114 faces towards the water supply tank 24 in a radial direction of the washing tank 111.

[0213] In an exemplary embodiment of the present disclosure, when the mopping and wiping part 200 of the cleaning device needs washing, the cleaning device moves to the cleaning base station 100 and cooperates with the cleaning base station 100, for example, for locking, to ensure stability of the mopping member 200 during washing of the mopping member 200. In this case, two mopping members 200 of the cleaning device are respectively located in the two washing tanks 111 and pressed against the two washing members 2. First, the drive mechanism 9 drives the suction nozzle 7 to move forwards to the limiting position. Therefore, when the cleaning device drives the two wiping members 200 to rotate, the washing member 2 is driven to rotate through friction between the two mopping members 200 and the washing member 2. When the washing member 2 rotates to a position where it abuts with the suction nozzle 7 in the limiting position, the washing member 2 is fixed relative to the washing tank 111. In this case, the washing member 2 is in the first washing state. An impact between the suction nozzle 7 and the washing member 2 can be better buffered by the buffer layer of the washing member 2. The mopping member 200 at a left side is adapted to rotate clockwise, allowing the washing member 2 at the left side to be abutted with a left side wall of the suction nozzle 7, and the mopping member 200 at a right side is adapted to rotate counterclockwise, allowing the washing member 2 at the right side to be abutted with a right side wall of the suction nozzle 7. In this way, the washing member 2 in the first washing state is prevented from shielding the filtering tank 13.

[0214] After the washing member 2 is fixed in the first washing state by the suction nozzle 7, the water supply box 10a feeds water into the first tank region 231 through the water supply passage, the water supply hole 114, and the water supply tank 24, and water fed into the first tank region 231 continues to flow into the second tank region 232. The cleaning device continues to drive the mopping member 200 to rotate relative to the washing member 2, and therefore a part of the mopping member 200 that sweeps across the water outlet channel 23 is wetted. Moreover, dirt on the mopping member 200 can be cleaned through mutual friction between the washing protrusion 25 at the upper surface of the washing member body 21 and the mopping member 200, and therefore the dirt on the mopping member 200 can enter the washing tank 111 with water flow to complete the washing operation on the mopping member 200. Generated sewage in this process may enter the filtering tank 13 through the communication notch 113.

[0215] After the washing of the mopping member 200 is completed, the drive mechanism 9 drives the suction nozzle 7 to move backwards to the non-limiting position to lift the restriction of the suction nozzle 7 on the washing member 2. As a result, the mopping member 200 can drive the washing member 2 to rotate relative to the washing tank 111 under the friction between the mopping member 200 and the washing member 2. Moreover, the bottom wall of the washing tank 111 is brushed by the first washing structure 213, and the inner peripheral wall of the washing tank 111 is brushed by the second washing structure. The water supply box 10a may feed water into the washing tank 111 through the water supply passage and the water supply hole 114 to rinse the inner wall of the washing tank 111 under agitation of the washing member 2. When the washing member 2 rotates relative to the washing tank 111, the washing member 2 sweeps across a part of the filtering tank 13 in the washing tank 111, and the dirt in the washing tank 111 can be driven into the filtering tank 13 through the agitation of the washing member 2. During the washing of the mopping member 200 and the washing tank 111, the drying air duct 51 may be closed by the first control valve, and the collecting air duct 61 may be closed by the second control valve. In this way, water vapor is prevented from entering the drying air duct 51 and the collecting air duct 61.

[0216] Further, sewage of the dirt entering the filtering tank 13 may flow downwards into the sewage buffer chamber 14 through the plurality of filtering holes 121 at the bottom wall of the filtering tank 13 and flow towards the connecting branch pipe 122. Subsequently, the sewage is discharged into the sewage box 10b through the sewage discharge tube 4 for storage. The filtering structure can block solid dirt on the filtering component 12, and a drying mode is initiated after the washing of the washing tank 111 is completed. In the drying mode, the first control valve is controlled to open the drying air duct 51, and the second control valve is controlled to close the collecting air duct 61. Therefore, the drying air duct 51 is in communication with the first passage 81. Under the driving of the drying fan, hot air in the drying air duct 51 is discharged into the filtering tank 13 through the first passage 81, the slide chamber 83, the first communication passage 7231, the second communication passage 7232, and the suction inlet 711, and further escapes into the washing tank 111 through the communication notch 113. Therefore, the drying assembly can perform drying treatment on the dirt in the filtering tank 13 and the mopping member 200 in the washing tank 111. The suction nozzle 7 is located at a rear end of the filtering hole 121 before the solid dirt in the filtering tank 13 is not dried, and a solid dirt collection mode is initiated after the drying of the dirt in the filtering tank 13 is completed. In the solid dirt collection mode, the first control valve is controlled to close the drying air duct 51, and the second control valve is controlled to open the collecting air duct 61. Therefore, the collecting air duct 61 is in communication with the second passage 82. The drive mechanism 9 drives the suction nozzle 7 to move forwards to scrape the solid dirt on the filtering structure through the scraping wall 712. Therefore, the solid dirt can be separated from the filtering structure, and under the action of the collecting fan, the solid dirt in the filtering tank 13 enters the dust collecting chamber through the suction inlet 711, the first communication passage 7231, the second communication passage 7232, the slide chamber 83, the second passage 82, and the collecting air duct 61 until the solid dirt in the filtering tank 13 is completely collected.

[0217] A cleaning system according to embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0218] The cleaning system according to the embodiments of the present disclosure comprises the cleaning base station 100 and a cleaning device adapted to cooperate with the cleaning base station 100, and the cleaning base station 100 is at least configured to wash the mopping member 200 of the cleaning device. For example, the cleaning base station 100 may only wash the mopping member 200 of the cleaning device, and may also wash a cleaning device body, etc., which is not specifically limited herein. Thus, through the cooperation between the cleaning base station 100 and the cleaning device cleanliness of the mopping member 200 can be better guaranteed to improve a cleaning effect of the cleaning device, and an automation level of the cleaning system can be better enhanced to facilitate improving user experience.

[0219] In an exemplary embodiment of the present disclosure, the cleaning device may move to drive the mopping member 200 to perform a ground sweeping and mopping operation. After a lot of dirt is adhered to the mopping member 200, the cleaning device may move to the cleaning base station 100 and cooperate with the cleaning base station 100 to perform the washing treatment on the mopping member 200 by using the cleaning base station 100. Meanwhile, dirt generated during the washing of the mopping member 200 flows into the filtering tank 13, and the filtering structure in the filtering tank 13 may separate sewage and solid dirt to facilitate classifying and treating different types of dirt. Thus, a treatment effect of the cleaning base station 100 on the dirt in the washing tank 111 can be better improved. After the washing of the mopping member 200 is completed, the cleaning device continues to perform the ground sweeping operation until a ground cleaning operation is completed.

[0220] In the cleaning system according to the embodiments of the present disclosure, the sewage can be better separated from the solid dirt through the filtering tank 13 to facilitate classifying and treating the different types of dirt. Meanwhile, since the washing member 2 is movably disposed in the washing tank, the solid dirt can be better prevented from accumulating on the inner wall of the washing tank 111 through the operation of the washing member 2 to clean the washing tank 111.
