Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and more specifically to a cleaning system. Background Technology

[0002] With the development of household cleaning equipment and the increasing demands of home users for cleaning results, floor scrubbers have become increasingly popular among consumers due to their high efficiency, convenience, environmental friendliness, and ability to be used both wet and dry. Floor scrubbers are typically equipped with a cleaning base station, which can automatically clean and maintain the machine. This includes functions such as automatically adding water, charging the machine, rinsing the wastewater tank, and discharging wastewater, further freeing up the user's hands.

[0003] Existing cleaning base stations have increased tray height due to the addition of drying air ducts or other components inside the tray. If the entire unit is lifted and placed on the tray, users will need to lift the unit to a higher height to place it on the tray to achieve the self-cleaning function. If the wastewater tank of the unit is full of wastewater, it will increase the weight of the unit, which is not conducive to use by users with less strength, and may even pose a risk of injury to the user.

[0004] If the entire unit is pushed directly into the tray in the forward direction, the brush assembly may be pushed back a certain distance from the tray due to the reaction force of the tilted body during the return operation after entering the tray. This could cause the entire unit to detach from the fixed position of the cleaning base station, making it prone to tipping over under external force. Utility Model Content

[0005] This disclosure provides a cleaning system to address the problems existing in the prior art.

[0006] According to a first aspect of this disclosure, a cleaning system is provided, comprising:

[0007] A cleaning device, comprising a floor brush assembly and a body cooperating with the floor brush assembly; the floor brush assembly is provided with a roller brush for cleaning a work surface;

[0008] A cleaning base station is configured to dock the cleaning equipment; the cleaning equipment has its forward direction as the side away from the user and its backward direction as the side facing the user; the cleaning base station has a storage space for the floor brush assembly to be pushed in and docked along the forward direction.

[0009] The cleaning base station is provided with an upwardly extending charging seat, and the bottom of the machine body is provided with a groove matched with the charging seat; the cleaning base station is provided with a limiting device configured to be located in the movement path of the ground brush assembly exiting the cleaning base station to stop the ground brush assembly; in the projection plane in the axial direction of the rolling brush, the limiting device at least partially overlaps with the rolling brush of the ground brush assembly parked in the storage space.

[0010] One beneficial effect of the present disclosure is that by providing a charging seat on the cleaning base station and a groove matched with the charging seat on the bottom of the machine body, a fixing is formed between the cleaning base station and the machine body of the cleaning device, so that the machine body can be more stably supported on the cleaning base station; in addition, by providing a limiting device on the cleaning base station and stopping the ground brush assembly in the movement path of the ground brush assembly exiting the cleaning base station through the limiting device, a fixing is formed between the cleaning base station and the ground brush assembly, so that the ground brush assembly can be more stably maintained in position, avoiding the ground brush assembly from retreating and causing the entire machine to disengage from the fixing and limiting of the cleaning base station when the machine body is homed after the ground brush assembly is in place. The present disclosure fixes the machine body and the ground brush assembly respectively, so that the cleaning device can be more stably supported on the cleaning base station, thereby avoiding tilting and improving the user's experience.

[0011] Other features and advantages of the present disclosure will become apparent from the following detailed description of exemplary embodiments thereof, taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

[0032] refer to Figure 1 and Figure 2 This disclosure provides a cleaning system, including a cleaning device 1 and a cleaning base station 2. For ease of description, in the following description, from the user's perspective, the side of the cleaning device 1 furthest from the user is referred to as the front side, and the side facing the user is referred to as the rear side. References Figure 2 From another perspective, the direction of the view can be considered as the front direction (the direction in which the cleaning device 1 is moving). Figure 2 The right side), the direction of retreat is recorded as the rear side ( Figure 2 (Left side).

[0033] The cleaning device 1 disclosed herein can be a handheld cleaning device, such as a handheld cleaning machine, a handheld wet vacuum cleaner, a handheld floor scrubber, a handheld fabric cleaner, or other handheld cleaning devices well known to those skilled in the art. It can also be a floor cleaning robot, a sweeping and mopping robot, or other self-moving cleaning devices well known to those skilled in the art. This embodiment uses a handheld floor scrubber as an example of the cleaning device 1. Figure 1As shown, the cleaning device comprises a floor brush assembly 11 and a machine body 12 cooperating with the floor brush assembly 11, wherein the floor brush assembly 11 is configured to clean the working surface. Specifically, the floor brush assembly 11 is rotatably connected with the machine body 12, and when the cleaning device 1 is parked on the working surface or is working on the working surface, the floor brush assembly 11 keeps in contact with the working surface. Further, a hand-held part (not shown in the figure) can also be arranged above the machine body 12, and after the cleaning device 1 is turned on, the user can hold the hand-held part to tilt and push and pull the machine body 12, so that the floor brush assembly 11 moves on the working surface to achieve the purpose of cleaning the dirt on the working surface; when the user holds the hand-held part to make the machine body 12 stand upright, the cleaning device 1 stops working.

[0034] In one embodiment of the present disclosure, as Figure 5 shown, the floor brush assembly 11 comprises a floor brush housing 111 and a roller brush 112 rotatably connected to the floor brush housing 111, and the roller brush 112 is used to clean the working surface. Wherein, the outer surface of the roller brush 112 can be provided with cleaning cotton, roller brush fluff or other cleaning elements for cleaning, so that the roller brush 112 can wet mop the working surface during rotation. As Figure 2 shown, the roller brush 112 can be rotatably connected to one side of the floor brush housing 111, and a walking wheel 114 can be arranged on the other side thereof, and the walking wheel 114 is rotated by the user exerting a forward or backward pushing force, or when the cleaning device 1 of the present disclosure is a cleaning robot, the walking wheel 114 is rotated under the action of its own driving force, so that the cleaning device 1 walks on the working surface.

[0035] A bracket 113 is arranged at the end of the roller brush 112, and the two sides in the axis direction of the roller brush 112 are defined as a driving side and a dismounting side respectively, and the bracket 113 can be arranged on the driving side and the dismounting side respectively. Wherein, the bracket on the dismounting side of the roller brush 112 can be a roller brush lifting bracket, and the roller brush 112 is rotatably connected to the inner wall of the roller brush lifting bracket. The user can dismount the roller brush 112 by dismounting the roller brush lifting bracket from the floor brush housing 111, so as to facilitate the user to replace the worn roller brush 112. It should be noted that the user usually comes to the front of the cleaning device 1 when he needs to replace the roller brush 112, at this time, the dismounting side can be located on the right side of the user, so as to facilitate the user to perform the dismounting operation with the right hand.

[0036] When installing the roller brush 112, the user only needs to hold the roller brush handle frame and insert the driving side of the roller brush 112 into the floor brush shell 111, so as to connect the driving side of the roller brush 112 to the driving motor, and then continue to insert the roller brush 112 into place so that the dismounting side of the roller brush 112 is completely inserted into the floor brush shell 111; then the roller brush handle frame can be installed to the floor brush shell 111, so as to rotationally connect the roller brush 112 to the floor brush shell 111. It should be noted that the support frame 113 usually has a certain thickness, so as to support the roller brush 112 at the dismounting side and support the driving motor at the driving side.

[0037] In one embodiment of the present disclosure, referring to Figure 2 and Figure 7 The machine body 12 is provided with a sewage tank 13, and the floor brush assembly 11 is provided with a clean water tank 14. The clean water tank 14 can provide liquid for the roller brush 112 to clean the working surface. Specifically, the floor brush assembly 11 can further include a liquid spraying mechanism, which can spray clean water or cleaning liquid in the clean water tank 14 onto the roller brush 112 or directly onto the working surface to be cleaned, so as to ensure the cleaning effect. The sewage tank 13 can be used to store the dirt after cleaning. Specifically, the floor brush assembly 11 can further include a sewage suction port, which can be used to suck the dirt after cleaning into the sewage tank 13 for storage, so as to facilitate subsequent centralized treatment.

[0038] The present disclosure sets the clean water tank 14 on the floor brush assembly 11, thereby reducing the weight of the machine body 12, so that the user can more easily push the machine body 12 of the cleaning device 1. In addition, the clean water tank 14 provided on the floor brush assembly 11 increases the downward pressure of the floor brush assembly 11, thereby improving the cleaning effect of the roller brush 112 on the working surface.

[0039] The cleaning base station 2 is configured to dock the cleaning device 1. Specifically, the cleaning base station 2 is used to place the cleaning device 1 and perform maintenance treatment on the cleaning device 1 docked thereon. For example, when the cleaning device 1 finishes cleaning the working surface, the user can dock it on the cleaning base station 2, so that the cleaning device 1 can be stably placed, and the cleaning base station 2 can perform self-cleaning, charging, sewage discharge, cleaning liquid replenishment and other treatments on the cleaning device 1 docked thereon, so as to facilitate the user to use it next time.

[0040] In one embodiment of the present disclosure, referring to Figure 1 and Figure 2The cleaning base station 2 comprises a base station body 20, a tray 22 is arranged at the bottom of the base station body 20, and a bearing part 21 for supporting the machine body 12 is arranged at a position above the tray 22 on the base station body 20, the bearing part 21 and the tray 22 are configured to extend outwardly from the same side of the base station body 20, and a receiving space for the mop assembly 11 to be pushed into and docked in the advancing direction is formed between the bearing part 21 and the tray 22.

[0041] Specifically, the base station body 20 is the main structure of the cleaning base station 2, and is internally provided with various functional components for maintaining the cleaning equipment 1, and provides a mounting basis for the bearing part 21 and the tray 22. The base station body 20 can extend in the height direction, and the bearing part 21 and the tray 22 can be spaced apart from each other in the height direction and respectively extend to the rear side, and the position between the bearing part 21 and the tray 22 forms a receiving space, which is located at the rear side of the base station body 20. Among them, the bearing part 21 is mainly used for supporting the machine body 12, and the tray 22 is mainly used for bearing the mop assembly 11, and the tray 22 can also be used for cleaning the mop assembly 11.

[0042] As mentioned above, the cleaning equipment 1 of the present disclosure is respectively provided with a clean water tank 14 and a dirty water tank 13 for storing liquid on the mop assembly 11 and the machine body 12. It can be understood that the components for storing liquid are generally heavy, and if they are supported on the same structure of the cleaning base station 2, the support will be unstable. The present disclosure separately arranges the tray 22 and the bearing part 21 on the base station body 20 to bear and support the mop assembly 11 and the machine body 12 respectively, so that the cleaning equipment 1 can be more stably supported on the cleaning base station 2, and the support stability is improved.

[0043] In a specific embodiment of the present disclosure, referring to Figure 7 A support wheel 213 can be arranged on the bottom surface of the bearing part 21, and the support wheel 213 extends into the receiving space to abut against the top surface of the mop assembly 11 when the mop assembly 11 is docked in the receiving space. The bearing part 21 is used for supporting the machine body 12 of the cleaning equipment 1. It can be understood that the machine body 12 itself is relatively heavy, and the bearing part 21 extending out of the base station body 20 does not have high strength, so in order to avoid deformation of the bearing part 21 under the weight of the machine body 12 during long-term use, the bearing part 21 needs to be further supported. The present disclosure arranges the support wheel 213 to further support the bearing part 21 on the mop assembly 11, thereby reducing the stress on the bearing part 21. During the process of the mop assembly 11 entering the receiving space, the top surface of the mop assembly 11 can be in rolling cooperation with the support wheel 213, so that the support effect is achieved while the top surface of the mop assembly 11 is not worn.

[0044] During parking, the brush assembly 11 is configured to enter the receiving space in the advancing direction with the front side thereof facing the cleaning base station 2. It can be understood that when using the cleaning device 1, the user usually stands behind the cleaning device 1 to hold the handheld part. The present disclosure sets the receiving space at the rear side of the cleaning base station 2, so that when the user pushes the cleaning device 1 into the cleaning base station 2 in the advancing direction, the user does not need to change the pushing direction, but can always push the cleaning device 1 forward, and the brush assembly 11 can enter the receiving space with the front side thereof facing the cleaning base station 2.

[0045] In one specific embodiment of the present disclosure, with reference to Figure 1 and Figure 2 A ramp surface 221 is arranged at the open side (i.e. the rear side) of the tray 22, and the brush assembly 11 can climb the ramp surface 221 during entry into the receiving space, so that the user can directly push the cleaning device 1 into the cleaning base station 2 without the need to lift the cleaning device 1 and then place it on the cleaning base station 2, thereby saving the user's physical strength and improving the user's experience. The open side of the tray 22 is the entry end for the brush assembly 11 to enter the receiving space, and the tray 22 also has a roller brush groove opposite the entry end and accommodating the roller brush 112. The advancing path of the tray 22 from the entry end to the roller brush groove is a continuous smooth surface. The path on the tray 22 for the brush assembly 11 to travel is configured as a smooth surface, so that when the user pushes the cleaning device 1, it can always be smooth and not jolt, avoiding the tray 22 being provided with a blocking member on the advancing path that hinders the brush assembly 11 from being pushed in, thereby making it difficult to push in.

[0046] Further, when the brush assembly 11 is parked in place, the roller brush 112 is located at the innermost position of the receiving space. A roller brush groove is arranged on the tray 22 corresponding to the position where the roller brush 112 is parked, thereby receiving dirt on the roller brush 112, and the roller brush 112 can be self-cleaned in the roller brush groove. Based on this, the present disclosure configures the tray 22 to be detachable relative to the base body 20. Dirt from the roller brush 112 is easily accumulated in the roller brush groove, and the user can periodically detach the tray 22 for cleaning, thereby keeping the tray 22 clean and hygienic, avoiding the tray 22 breeding bacteria and producing odors, thereby improving the user's experience.

[0047] With reference to Figure 9, the base station 2 is provided with an upwardly extending charging seat 24, and the bottom of the machine body 12 is provided with a recess matched with the charging seat 24, wherein the charging seat 24 is arranged on the bearing part 21, the front side of the charging seat 24 is configured as a guide arc surface 241 extending upwardly and obliquely from the end surface of the bearing part 21, and the center of the guide arc surface 241 is located on the rotation axis of the machine body 12 relative to the brush assembly 11; the rear side of the charging seat 24 is configured as a plane extending upwardly from the end surface of the bearing part 21. The machine body 12 is configured to rotate forward relative to the brush assembly 11 to be supported on the bearing part 21 after the brush assembly 11 is in place, so as to realize the homing operation.

[0048] The charging seat 24 is used to charge the cleaning device 1 and to limit the parking of the machine body 12 of the cleaning device 1. When parking, the user needs to first push the brush assembly 11 into the storage space, and then rotate the machine body 12 to the home position, so that the recess at the bottom of the machine body 12 is embedded on the charging seat 24, thereby stably parking the machine body 12 on the bearing part 21. The guide arc surface 241 at the front side of the charging seat 24 is configured as a circular arc, and the center of the circular arc is the hinge point between the machine body 12 and the brush assembly 11. Thus, when the machine body 12 rotates, the rotation path of the recess matches the guide arc surface 241, and the recess can only be embedded in or separated from the charging seat 24 when the machine body 12 rotates. In this way, when the machine body 12 is parked in place, that is, the charging seat 24 is embedded in the recess, when the machine body 12 is subjected to an external force in a non-rotation direction, the recess cannot be separated from the charging seat 24. Only when the user actively applies a rotating force to the machine body 12, the recess can be separated from the charging seat 24. Thus, the stability of the parking of the machine body 12 is improved, the machine body 12 is less likely to fall after parking, and the user experience is improved.

[0049] In one specific embodiment of the present disclosure, with continued reference to Figure 9 The top end surface of the charging seat 24 is configured to extend downwardly and obliquely from front to back. It should be noted that the top end surface of the charging seat 24 referred to herein does not include the guide arc surface 241, and this part of the top end surface is configured as an inclined surface with a higher front side and a lower rear side. The part of the recess matched with the guide arc surface 241 can be configured as a completely matching shape, and for the part matched with the top end surface of the charging seat 24, the groove wall can be configured to extend horizontally. In this embodiment, in the matching state, the gap between the front side inner wall of the recess and the top end surface of the charging seat 24 is small, and the gap at the rear side is large. When the user rotates the machine body 12 backward to cancel the parking, the gap at the rear side of the recess can provide sufficient space for avoiding, so that part of the inner wall of the recess and the guide arc surface 241 remain in sliding cooperation, and the charging seat 24 does not jam the recess, thereby ensuring that the user can easily remove the parking state of the machine body 12.

[0050] In one embodiment of the present disclosure, with reference to Figure 9The bearing part 21 is provided with a sewage inlet 211, and the charging seat 24 is provided with two charging seats 24 which are arranged on both sides of the sewage inlet 211 and are arranged higher than the end face of the sewage inlet 211. As described above, the bearing part 21 is used for bearing the machine body 12 provided with the sewage tank 13, and the sewage inlet 211 is used for docking with the sewage tank 13, so as to realize the sewage discharge function of the cleaning base station 2. When the docking is normal, the sewage in the sewage tank 13 can completely flow into the sewage inlet 211 for subsequent sewage discharge; and when accidental leakage occurs, the sewage in the sewage tank 13 can flow to an area outside the sewage inlet 211. In the present disclosure, the charging seat 24 is arranged higher than the end face of the sewage inlet 211, so that the accidentally flowing sewage cannot contaminate the charging terminal 242 on the top surface of the charging seat 24, thereby avoiding circuit failure.

[0051] In a specific embodiment of the present disclosure, a sealing rubber 212 is arranged at the sewage inlet 211, and the sealing rubber 212 can be made of elastic sealing materials such as rubber and silicone. When the sewage tank 13 is docked with the sewage inlet 211, the sealing rubber 212 can seal the docking position, so as to ensure successful docking and prevent sewage leakage.

[0052] The charging terminal 242 is arranged movably on the top of the charging seat 24, and in a specific embodiment of the present disclosure, the charging terminal 242 can be movably connected to the charging seat 24 through an elastic device 243. The elastic device 243 can ensure that the charging terminal 242 has an upward movement tendency. During the process of parking the machine body 12, the shell structure of the machine body 12 can press the charging terminal 242 downward; after parking in place, the charging seat 24 is located in the groove, and the charging terminal 242 is upwardly bounced to fully contact with the inner wall of the groove under the elastic force of the elastic device 243, so as to ensure the stability of the circuit connection and improve the quality of charging.

[0053] The above describes a specific way of the present disclosure for parking and limiting the machine body 12. In actual application, the user needs to first push the brush assembly 11 into the storage space, and then rotate the machine body 12. After rotating to a position, the groove can be limited and matched with the charging seat 24. However, during the rotation process, the brush assembly 11 will be subjected to a reaction force, and thus has a backward driving tendency. When the machine body 12 has not been rotated to a position, the brush assembly 11 can have exited the storage space, so that after the machine body 12 is rotated to a corresponding angle, the groove cannot be matched with the charging seat 24. In order to solve the above problem, the brush assembly 11 also needs to be parked and limited.

[0054] Reference Figure 5 and Figure 6A limiting device 23 is provided on the cleaning base station 2. The limiting device 23 is configured to be located in the movement path of the floor brush assembly 11 as it exits the cleaning base station 2, thereby stopping the floor brush assembly 11. On the projection plane along the axial direction of the roller brush 112, the limiting device 23 at least partially overlaps with the roller brush 112 of the floor brush assembly 11 resting in the storage space. Specifically, the limiting device 23 is configured to be disposed on the tray 22 and to abut against the bracket 113. As mentioned above, the bracket 113 is disposed on the side of the roller brush 112, so the limiting device 23, which abuts against the bracket 113, will not directly contact the roller brush 112. The roller brush 112 can still rotate freely in the roller brush groove on the tray 22 for self-cleaning, and the limiting device 23 will not interfere with the self-cleaning operation of the roller brush 112.

[0055] As mentioned above, two brackets 113 can be provided, and therefore two corresponding limiting devices 23 can also be provided on the tray 22. The two limiting devices 23 support the two brackets 113 respectively, and the two limiting devices 23 can be located on the same horizontal line, thus ensuring that the floor brush assembly 11 will not be tilted. This disclosure improves the stability of the limiting by providing two limiting devices 23 to limit the stopping on both sides of the floor brush assembly 11.

[0056] Furthermore, such as Figure 5 As shown, the bracket 113 includes an end cap 1131 coaxial with the roller brush 112. The limiting device 23 abuts against the outer edge of the end cap 1131, and the position abutting against the end cap 1131 is located on the lower side behind the center of the end cap 1131, and higher than the lowest point of the end cap 1131. The bracket 113 includes a circular end cap 1131 and a plate extending rearward from the end cap 1131. A portion of the end cap 1131 is coaxially arranged with the roller brush 112. The portion of the plate extends in a straight line in the front-rear direction, so it is not convenient to abut against the limiting device 23; while the portion of the end cap 1131 is constructed to be circular. Under the pushing force applied by the user, the end cap 1131 can drive into the storage space along with the floor brush assembly 11 and pass forward past the limiting device 23. The lowest end of the end cap 1131 passes past the limiting device 23 and is located in front of it, so that the rear side of its bottom end cap abuts against the limiting device 23. If the external force does not exceed the threshold, the bottom of the end cap 1131 cannot move backward past the limiting device 23, thus achieving the stopping and limiting of the floor brush assembly 11.

[0057] Specifically, such as Figure 6As shown, the limiting device 23 includes a limiting piece 231 movably connected to the tray 22, and a limiting spring 232 arranged between the limiting piece 231 and the tray 22. The limiting piece 231 is configured to move downward when subjected to an external force, and to be pushed upward by the force of the limiting spring 232 after the external force is removed. The front and rear sides of the limiting piece 231 can be configured as inclined surfaces. When the floor brush assembly 11 enters the storage space, the end cover 1131 can press the rear side inclined surface of the limiting piece 231, thereby compressing the limiting spring 232, so that the end cover 1131 passes forward of the limiting device 23. After the end cover 1131 passes the limiting device 23, the limiting piece 231 springs up under the elastic force of the limiting spring 232 and abuts against the bottom rear side of the end cover 1131, because the external force on the limiting piece 231 is removed. Similarly, when the floor brush assembly 11 exits the storage space, the end cover 1131 can press the front side inclined surface of the limiting piece 231 under the external force applied by the user, thereby compressing the limiting spring 232, so that the end cover 1131 can pass backward of the limiting device 23. At this time, the floor brush assembly 11 is no longer limited, and thus can be easily taken out.

[0058] The present disclosure forms a fixation between the cleaning base station 2 and the body 12 of the cleaning device 1 by arranging the charging seat 24 on the cleaning base station 2 and arranging the groove cooperating with the charging seat 24 on the bottom of the body 12, so that the body 12 can be more stably supported on the cleaning base station 2. In addition, the present disclosure forms a fixation between the cleaning base station 2 and the floor brush assembly 11 by arranging the limiting device 23 on the cleaning base station 2 and stopping the floor brush assembly 11 in the movement path of the floor brush assembly 11 exiting the cleaning base station 2 by the limiting device 23, so that the floor brush assembly 11 can be more stably kept in position and avoid the floor brush assembly 11 from retreating to cause the whole machine to be out of the fixation and limitation of the cleaning base station 2 when the body 12 is homed after the floor brush assembly 11 is in position. The present disclosure fixes the body 12 and the floor brush assembly 11 respectively, so that the cleaning device 1 can be more stably supported on the cleaning base station 2, thereby avoiding tilting and improving the user's experience.

[0059] In an embodiment of the present disclosure, referring to Figure 2 and Figure 3 The bottom of the sewage tank 13 is arranged with a sewage outlet 131 for docking with the sewage inlet 211, and a sewage cover 132 hinged on the sewage tank 13 and used for plugging the sewage outlet 131. The sewage outlet 131 can be a dirty outlet of the sewage tank 13. When the body 12 is docked in position, the sewage outlet 131 is docked with the sewage inlet 211, at which time the sewage cover 132 can be opened, so that the dirt in the sewage tank 13 is discharged from the sewage outlet 131 into the sewage inlet 211 for further sewage treatment by the cleaning base station 2.

[0060] Specifically, as Figure 3As shown, a locking piece 133 is movably connected to the pollution discharge cover 132 by a locking spring 1332. A push rod 134 is movably arranged on the machine body 12. When the pollution discharge cover 132 is in an open state, the push rod 134 is configured to move forward to lift the pollution discharge cover 132 to close the pollution discharge port 131, and in the state that the pollution discharge cover 132 closes the pollution discharge port 131, the locking piece 133 is configured to extend to cooperate with a locking port 1311 arranged on the sewage tank 13 under the action of the locking spring 1332.

[0061] The locking port 1311 can be a notch arranged on the inner side wall of the pollution discharge port 131. The locking piece 133 is elastically mounted on the pollution discharge cover 132, and in a natural state, the length of the locking piece 133 is greater than that of the pollution discharge cover 132. The top end of the locking piece 133 is provided with a first guide surface 1333, and the inner side wall of the pollution discharge port 131 provided with the locking port 1311 is provided with a second guide surface 1312 for cooperating with the first guide surface 1333. Under the pushing action of the push rod 134, the pollution discharge cover 132 and the locking piece 133 rotate together to the closing position; when rotating to the case that the locking piece 133 is removed from the inner wall of the pollution discharge port 131, the first guide surface 1333 and the second guide surface 1312 slide cooperate, the inner wall of the pollution discharge port 131 pushes the locking piece 133 to drive the locking spring 1332 to compress, at this time, the pollution discharge cover 132 and the locking piece 133 continue to rotate together under the action of the push rod 134; when the locking piece 133 moves to the position cooperating with the locking port 1311, the locking piece 133 is driven by the locking spring 1332 to pop out, thereby extending into the locking port 1311 to lock, at this time, the pollution discharge cover 132 closes the pollution discharge port 131.

[0062] When the pollution discharge cover 132 is in a closed state, the push rod 134 is configured to move backward to drive the locking piece 133 to disengage from the locking port 1311 to open the pollution discharge cover 132. Specifically, a transmission hook 1341 is arranged at the front end of the push rod 134, and a transmission flange 1331 is arranged at the rear end of the locking piece 133 for cooperating with the transmission hook 1341. When the pollution discharge cover 132 is in a closed state, the transmission hook 1341 cooperates with the transmission flange 1331, and when the push rod 134 moves backward, the transmission hook 1341 can drive the locking piece 133 to disengage from the locking port 1311 through the transmission flange 1331, thereby releasing the locking, and the locking piece 133 drives the pollution discharge cover 132 to open.

[0063] In one embodiment of the present disclosure, reference is made to Figure 2The base station body 20 is provided with a detachable containing box, and the containing cavity of the containing box is divided into a sewage space 202 at the top and a clean water space 203 at the bottom by a soft film 201; the soft film 201 is configured to bulge upwards when the pressure of the clean water space 203 is greater than that of the sewage space 202, and to sag downwards when the pressure of the sewage space 202 is greater than that of the clean water space 203, so as to adjust the volume ratio of the clean water space 203 and the sewage space 202. The disclosure divides the containing cavity into two by providing the soft film 201 to form the clean water space 203 and the sewage space 202, wherein the clean water space 203 is used to store clean water to be delivered to the cleaning equipment 1; the sewage space 202 is used to temporarily store sewage discharged from the sewage tank 13 of the cleaning equipment 1, and sewage generated by self-cleaning of the roller brush 112, etc.; the soft film 201 can be made of a water-tight flexible material, so that the clean water space 203 and the sewage space 202 are isolated from each other.

[0064] When there is more liquid in the sewage space 202, thereby forming a larger pressure on the upper side of the soft film 201, the soft film 201 sags downwards, thereby increasing the volume of the sewage space 202 and correspondingly reducing the volume of the clean water space 203. When there is more liquid in the clean water space 203, thereby forming a larger pressure on the lower side of the soft film 201, the soft film 201 bulges upwards, thereby increasing the volume of the clean water space 203 and correspondingly reducing the volume of the sewage space 202. The sewage space 202 and the clean water space 203 of the disclosure share a containing cavity space. Compared with the prior art which uses a hard structure to separate the space, the use of the soft film 201 to separate can automatically adjust the respective volume ratios of the sewage space 202 and the clean water space 203 based on the actual water usage, so as to be applicable to more diverse application scenarios.

[0065] In an embodiment of the disclosure, a spraying piece can be provided on the top of the sewage tank 13, and the cleaning base station 2 can be provided with a clean water channel communicating with the clean water space 203. When the cleaning equipment 1 is docked in place, the clean water channel can be communicated to the spraying piece, and the clean water in the clean water space 203 can be delivered to the spraying piece on the top of the sewage tank 13 through the clean water channel, and the clean water can be sprayed to the inner wall of the sewage tank 13 and other positions, so as to realize comprehensive cleaning of the sewage tank 13 and the sewage cover 132.

[0066] In an embodiment of the disclosure, referring to Figure 2 and Figure 4A detachable solid-liquid separator 204 is arranged on the top of the containing box, and is configured to communicate with the sewage inlet 211 through a sewage inlet pipe 205. The dirty in the sewage inlet pipe 205 is configured to enter the sewage space 202 after being separated by the solid-liquid separator 204. A handle exposed outside the containing box is arranged on the top of the solid-liquid separator 204. The solid-liquid separator 204 can be used for solid-liquid separation of the dirty. It can be understood that, in addition to liquid such as sewage, the dirty from the sewage tank 13 of the cleaning device 1 also contains solid waste such as hair, paper pieces and debris. During subsequent sewage discharge to the sewer, the solid waste is easy to cause blockage. Therefore, the solid-liquid separator 204 is arranged in the base station body 20, so that the dirty entering the cleaning base station 2 is filtered, and the solid waste can be filtered out by the solid-liquid separator 204, thereby avoiding the problem of blockage caused by subsequent discharge. Further, the solid-liquid separator 204 can be configured to be detachably arranged on the top of the containing cavity. When used for a period of time, the user can remove the solid-liquid separator 204 by the handle of the solid-liquid separator 204 exposed outside the containing box for dumping, so as to clean the solid waste therein.

[0067] The dirty from the sewage tank 13 of the cleaning device 1 can flow into the sewage inlet pipe 205 through the sewage outlet 131 and the sewage inlet 211 in sequence, and then enter the solid-liquid separator 204 for solid-liquid separation. The liquid sewage can enter the sewage space 202, so as to be prepared for subsequent discharge. However, as shown in Figure 2 , the solid-liquid separator 204 is arranged on the top of the containing cavity, and the position is obviously higher than the sewage inlet 211. Therefore, in order to enable the dirty in the sewage inlet pipe 205 to flow to the solid-liquid separator 204 against gravity, a negative pressure environment can be formed in the sewage space 202.

[0068] In one embodiment of the present disclosure, continuing to refer to Figure 2 and Figure 4 , the negative pressure motor 25 is arranged on the base station body 20 at a position located at the bottom of the containing box. The air inlet of the negative pressure motor 25 is configured to communicate with the sewage space 202 through the negative pressure air duct 251. The negative pressure motor 25 can extract air in the sewage space 202 through the negative pressure air duct 251 when turned on, so as to form a negative pressure environment in the sewage space 202. At this time, the cleaning device 1 is parked on the cleaning base station 2, and the sewage outlet 131 of the sewage tank 13 is docked to the sewage inlet 211. When the sewage cover 132 is opened, the negative pressure sewage space 202 communicates with the sewage tank 13 through the sewage inlet pipe 205, so that the dirty in the sewage tank 13 can flow to the sewage space 202 in the sewage inlet pipe 205 against gravity under the action of the negative pressure.

[0069] Further, as shown in Figure 2As shown, the drying air duct 252 is arranged on the base body 20 and located in front of the roller brush 112. The drying air duct 252 can be arranged below the negative pressure motor 25. One end of the drying air duct 252 is in communication with the air outlet of the negative pressure motor 25, and the other end is configured to extend to a position corresponding to the roller brush 112 of the floor brush assembly 11. A heating element 26 is arranged in the drying air duct 252. The negative pressure motor 25 can discharge exhaust gas from the air outlet during the process of pumping air from the sewage space 202. The exhaust gas is introduced into the drying air duct 252 and heated by the heating element 26, such as a PTC, to form hot air. The hot air can be blown to the roller brush 112 to dry the wet roller brush 112 after work or self-cleaning. In this way, in the internal circulation system formed by the cleaning device 1 and the cleaning base station 2, the gas circulation is realized by one negative pressure motor 25. The negative pressure motor 25 forms a negative pressure environment in the sewage space 202, and also uses the pumped air to dry the roller brush 112. The dried roller brush 112 is less likely to breed bacteria and avoid odor, improving the user experience.

[0070] In one embodiment of the present disclosure, the cleaning device 1 is also provided with a throat pipe 15 arranged between the floor brush assembly 11 and the machine body 12 and configured to deform under external force. When the user holds the hand-held part to rotate the machine body 12 relative to the floor brush assembly 11, the throat pipe 15 can deform with it. One end of the throat pipe 15 located at the floor brush assembly 11 is configured to communicate to the sewage suction port. The dirt generated by the roller brush 112 during cleaning can enter the throat pipe 15 through the sewage suction port. In the parking state, the dirt generated by the self-cleaning of the roller brush 112 is located in the roller brush groove of the tray 22. At this time, the sewage suction port can be directly opposite the roller brush groove, so that the dirt generated by the self-cleaning of the roller brush 112 can also enter the throat pipe 15 through the sewage suction port. One end of the throat pipe 15 located at the machine body 12 is in communication with the sewage tank 13, so as to transport the dirt from the sewage suction port to the sewage tank 13.

[0071] As described above, the negative pressure motor 25 can form a negative pressure environment in the sewage space 202 after being turned on. The sewage space 202 is in communication with the sewage tank 13 through the sewage inlet pipe 205, and the sewage tank 13 is in communication with the roller brush groove through the throat pipe 15. Therefore, the dirt generated by the self-cleaning of the roller brush 112 can flow against gravity under the action of negative pressure, sequentially through the throat pipe 15, the sewage tank 13, the sewage inlet pipe 205, and finally flow into the sewage space 202. It can be seen that the cleaning device 1 and the cleaning base station 2 of the present disclosure can form an internal circulation water and gas system. The dirt in each part of the system can finally be collected in the sewage space 202 for centralized treatment under the action of the negative pressure motor 25 in the cleaning base station 2, improving the degree of automation of the cleaning system. The user does not need to clean the roller brush groove, the sewage tank 13 and other structures by himself, thereby improving the user experience.

[0072] In addition, in the process of drying the rolling brush 112, the hot air formed by the heating element 26 in the drying air duct 252 also blows into the throat pipe 15 and passes through the sewage tank 13, the sewage inlet pipe 205, and then blows to the solid-liquid separation piece 204. The solid-liquid separation piece 204 has residual liquid on the separated solid waste, and the residual liquid can be dried by the hot air, so that the solid waste in the solid-liquid separation piece 204 remains dry. The solid waste accumulated in the solid-liquid separation piece 204 can remain dry and is not prone to bacterial growth and odor generation, so the user does not need to clean the solid-liquid separation piece 204 frequently, thereby improving the user experience.

[0073] In one embodiment of the present disclosure, with reference to Figure 7 and Figure 8 The water injection joint 206 is movably connected to the base body 20, specifically, the water injection joint 206 is exposed to the storage space, one end of the water injection joint 206 can be configured to communicate with the clean water space 203 through the water injection pipe, and the other end can be configured to extend into the storage space. The clean water tank 14 is provided with a water injection port 141 that is matched with the water injection joint 206. When the ground brush assembly 11 is docked in place, the end of the water injection joint 206 in the storage space can extend into the water injection port 141, thereby communicating the water path between the clean water space 203 and the clean water tank 14, and the cleaning base 2 can inject clean water into the clean water tank 14.

[0074] Specifically, as Figure 8 shown, the base body 20 is provided with a through hole 207, the water injection joint 206 is sleeved with a first rubberized part 2061, and the first rubberized part 2061 is configured to have an umbrella-shaped structure that expands outward; at least part of the umbrella-shaped structure of the first rubberized part 2061 is located in the through hole 207, thereby providing a movable space for the water injection joint 206. The diameter of the body of the water injection joint 206 is smaller than the inner diameter of the through hole 207, and the diameter of at least part of the umbrella-shaped structure of the first rubberized part 2061 that expands outward is matched with the inner diameter of the through hole 207, so that the water injection joint 206 can be connected in the through hole 207 through the first rubberized part 2061. Due to the softness of the first rubberized part 2061, the water injection joint 206 has a degree of freedom of movement relative to the through hole 207.

[0075] It can be understood that the user adopts a pushing manner to dock the cleaning device 1 to the cleaning base station 2, and thus allows a certain docking error to exist. The floor brush assembly 11 docked in place within the allowable error range, and the water injection port 141 of the clean water tank 14 thereof can not be completely aligned with the water injection connector 206. At this time, the user does not need to perform careful alignment, but can continue to push the cleaning device 1 forward, and the water injection connector 206 can fine-tune its directly opposite position by compressing the first rubberized portion 2061, so as to move to the position capable of being docked with the water injection port 141. It can be seen that the water injection connector 206 of the present disclosure can realize the functions of automatic calibration, automatic guidance and self-adaptation, and ensures that the water injection port 141 of the water injection connector 206 can be accurately docked, and the user does not need to manually align, thereby improving the user experience.

[0076] In an embodiment of the present disclosure, with continued reference to Figure 8 , the side of the water injection connector 206 located inside the base station body 20 is provided with a second rubberized portion 2062, which is configured in an outwardly expanded umbrella-shaped structure and located outside the through hole 207, and the umbrella-shaped structure end of the second rubberized portion 2062 is arranged towards the wall surface of the outer periphery of the through hole 207. The second rubberized portion 2062 can limit the end of the water injection connector 206 located inside the base station body 20, preventing the water injection connector 206 from being pulled out of the base station body 20. At the same time, the second rubberized portion 2062 also has the characteristics of softness and deformability, and thus can also provide a certain movement space for the water injection connector 206. The second rubberized portion 2062 allows the water injection connector 206 to have a certain amount of free movement, and also prevents it from falling off.

[0077] The water injection connector 206 located outside the base station body 20 is provided with a flange 2063 for abutting against the side wall of the base station body 20, and the distance between the flange 2063 and the second rubberized portion 2062 is greater than the wall thickness of the side wall of the base station body 20, so as to provide a movement space for the water injection connector 206. The flange 2063 can limit the end of the water injection connector 206 located outside the base station body 20, preventing the water injection connector 206 from falling into the base station body 20. The difference between the distance between the flange 2063 and the second rubberized portion 2062 and the wall thickness of the side wall of the base station body 20 is the movable freedom degree of the water injection connector 206 in the extension direction thereof, and the limiting structures at both ends ensure that the water injection connector 206 always does not fall off the through hole 207 during movement.

[0078] In an embodiment of the present disclosure, the water injection port 141 is provided with a water injection valve 142, and the water injection valve 142 is pre-pressed to close the water injection port 141 by a water valve spring 1421. After the water injection connector 206 extends into the water injection port 141, the water injection valve 142 can be pushed open and the water valve spring 1421 can be compressed, so as to open the water injection port 141. Figure 8 As shown in FIG. 8, the water injection connector 206 is provided with a water injection valve 142, and the water injection valve 142 is pre-pressed to close the water injection port 141 by a water valve spring 1421. After the water injection connector 206 extends into the water injection port 141, the water injection valve 142 can be pushed open and the water valve spring 1421 can be compressed, so as to open the water injection port 141. Figure 8The sealing ring 2064 is arranged at the position of the middle right side. When the water injection connector 206 has been inserted into the water injection port 141 and has not yet pushed open the water injection valve 142, the sealing ring 2064 is inserted into the water injection port 141 along with the water injection connector 206. The sealing ring 2064 is pre-pressed against the inner wall of the water injection port 141, thereby sealing the water injection port 141 in advance and preventing water leakage when the water injection port 141 is opened.

[0079] After the water injection is completed, the floor brush assembly 11 drives the clean water tank 14 to move away from the storage space, and the water injection connector 206 begins to gradually exit the water injection port 141. The pushing resistance on the water injection valve 142 is removed, and the water injection valve 142 moves in the direction of sealing the water injection port 141 under the elastic force of the water valve spring 1421. Before the water injection valve 142 is completely reset to seal the water injection port 141, the sealing ring 2064 continues to pre-press the inner wall of the water injection port 141. After the water injection valve 142 is reset, the sealing ring 2064 exits the water injection port 141. In this way, the water injection port 141 is always sealed during the entire process of the water injection connector 206 exiting the water injection port 141, and water leakage does not occur. Figure 8

[0080] Application scenario one

[0081] In the household cleaning scenario, the cleaning device 1 can be a handheld scrubber. The user can hold the handheld part to tilt the machine body 12 and push and pull back and forth, so that the floor brush assembly 11 moves on the working surface to achieve the purpose of cleaning the dirt on the working surface. When the handheld scrubber finishes cleaning the working surface, the user can park it on the cleaning base station 2. In this way, not only can the handheld scrubber be stably placed, but also the cleaning base station 2 can perform self-cleaning, charging, sewage discharge, and cleaning liquid replenishment on the handheld scrubber parked on it, so as to be ready for the next use by the user.

[0082] When parking the handheld scrubber on the cleaning base station 2, since the path on the tray 22 for the floor brush assembly 11 to travel can be configured as a smooth surface, and the inclined surface 221 is arranged on the opening side (i.e., the rear side) of the tray 22, the user can directly push the handheld scrubber into the cleaning base station 2. During parking, the floor brush assembly 11 is configured to enter the storage space with its front side facing the cleaning base station 2.

[0083] ​The limiting device 23 is arranged on the tray 22 and is configured to be located in the movement path of the floor brush assembly 11 exiting the cleaning base station 2 to stop the floor brush assembly 11. In the projection plane along the axial direction of the roller brush 112, the limiting device 23 at least partially overlaps the roller brush 112 of the floor brush assembly 11 parked in the storage space. When the floor brush assembly 11 enters the storage space, the end cover 1131 can press the rear inclined surface of the limiting piece 231, thereby compressing the limiting spring 232, so that the end cover 1131 passes forward beyond the limiting device 23. After the end cover 1131 passes beyond the limiting device 23, the limiting piece 231 springs up under the elastic force of the limiting spring 232 due to the removal of the external force thereon and abuts against the bottom rear position of the end cover 1131. In this way, a fixed relationship is formed between the cleaning base station 2 and the floor brush assembly 11, so that the floor brush assembly 11 can be more stably kept in position.

[0084] After the floor brush assembly 11 is fixed, the user can rotate the machine body 12 to park the machine body 12 in place. During rotation, the floor brush assembly 11 will be subjected to a reaction force from the machine body 12, but under the action of the limiting device 23, the floor brush assembly 11 will not retreat and can remain in place during rotation of the machine body 12.

[0085] The user rotates the machine body 12 so that the groove at the bottom of the machine body 12 is embedded on the charging seat 24, thereby stably parking the machine body 12 on the bearing part 21. The guide arc surface 241 at the front side of the charging seat 24 is configured as a circular arc, and the center of the circle is the hinge point between the machine body 12 and the floor brush assembly 11. Thus, when the machine body 12 is rotated, the rotation path of the groove matches the guide arc surface 241, and the groove can only be embedded or separated from the charging seat 24 when the machine body 12 is rotated, thereby improving the stability of parking of the machine body 12, and the machine body 12 is less likely to tip over after parking in place.

[0086] The present disclosure fixes the machine body 12 and the floor brush assembly 11 respectively, avoids the floor brush assembly 11 from retreating and causing the entire machine to be separated from the fixing and limiting of the cleaning base station 2 when the machine body 12 is returned to position after the floor brush assembly 11 is in place, so that the handheld scrubber can be more stably supported on the cleaning base station 2, thereby avoiding tipping over and improving the user's experience.

[0087] When the handheld scrubber needs to be taken off from the cleaning base station 2 for cleaning the working surface again, the user first needs to rotate the machine body 12 to disengage the recess from the charging seat 24, thereby releasing the location fixing of the machine body 12; then the user drags the floor brush assembly 11 out of the storage space, under the action of the external force applied by the user, the end cover 1131 can press the front inclined surface of the limiting piece 231, thereby compressing the limiting spring 232, so that the end cover 1131 can pass the limiting device 23 backward, at this time, the floor brush assembly 11 is no longer limited, and thus can be easily taken out.

[0088] Application scenario two

[0089] In the household cleaning scenario, the cleaning device 1 can be a handheld scrubber, and the floor brush assembly 11 is provided with a clean water tank 14. When the handheld scrubber finishes cleaning the working surface, the user can park it on the cleaning base station 2, and the cleaning base station 2 can supplement the cleaning liquid to the clean water tank 14 for the next use of the user.

[0090] The water injection connector 206 is movably connected to the base body 20, one end of the water injection connector 206 is configured to communicate with the clean water space 203 through the water injection pipeline, and the other end is configured to extend into the storage space; the clean water tank 14 is configured to have a water injection port 141 for docking with the water injection connector 206. When the floor brush assembly 11 is parked in place, the end of the water injection connector 206 in the storage space can extend into the water injection port 141, thereby connecting the water path between the clean water space 203 and the clean water tank 14, and the cleaning base station 2 can inject clean water into the clean water tank 14.

[0091] The water injection port 141 is provided with a water injection valve 142, and the water injection valve 142 is pre-pressed to close the water injection port 141 by a water valve spring 1421. After the water injection connector 206 extends into the water injection port 141, the water injection valve 142 can be pushed open and the water valve spring 1421 is compressed, thereby opening the water injection port 141. Figure 8 Figure 8 As shown in FIG. 6, the water injection connector 206 is provided with a sealing ring 2064, when the water injection connector 206 has extended into the water injection port 141 and has not yet pushed open the water injection valve 142, the sealing ring 2064 extends into the water injection port 141 together with the water injection connector 206, and the sealing ring 2064 is pre-pressed to the inner wall of the water injection port 141, thereby sealing the water injection port 141 in advance to prevent water leakage when the water injection port 141 is opened.

[0092] After water filling is complete, as the floor brush assembly 11 moves the clean water tank 14 away from the storage space, the water filling connector 206 gradually retracts from the water inlet 141. The resistance force on the water filling valve 142 is removed, and therefore, under the elastic force of the water valve spring 1421, it moves towards sealing the water inlet 141. Before the water filling valve 142 fully returns to its sealed position, the sealing ring 2064 continuously pre-presses the inner wall of the water inlet 141 until the water filling valve 142 returns to its original position, at which point the sealing ring 2064 retracts from the water inlet 141. This ensures that the water inlet 141 remains sealed throughout the entire process of the water filling connector 206 retracting from the water inlet 141, preventing any leakage.

[0093] Furthermore, within the allowable error range, the water inlet 141 of the clean water tank 14 of the floor brush assembly 11, once docked, may not be perfectly aligned with the water inlet connector 206. In this case, the user does not need to perform careful alignment; instead, they can continue to push the handheld floor scrubber forward. The water inlet connector 206 can then fine-tune its alignment by compressing the first rubber-coated part 2061, thus moving it to align with the water inlet 141. Therefore, the water inlet connector 206 of this disclosure can achieve automatic calibration and automatic guidance adaptive functions, ensuring accurate alignment of the water inlet 141 without requiring manual alignment by the user, thus improving the user experience.

[0094] Application Scenario 3

[0095] In a home cleaning scenario, cleaning device 1 can be a handheld floor scrubber. The handheld floor scrubber's body 12 is equipped with a wastewater tank 13. While cleaning with the floor brush assembly 11, the dirty water can be sucked into the wastewater tank 13 through the suction port for storage, facilitating subsequent centralized treatment. After the handheld floor scrubber has finished cleaning the work surface, the user can park it on the cleaning base station 2 for wastewater disposal.

[0096] A sewage inlet 211 is provided on the support part 21 of the clean base station 2. The support part 21 is used to support the body 12 on which the sewage tank 13 is installed. The sewage inlet 211 is used to connect with the sewage tank 13. A sewage outlet 131 is provided at the bottom of the sewage tank 13 for connecting with the sewage inlet 211, and a sewage cover 132 is hinged to the sewage tank 13 for sealing the sewage outlet 131.

[0097] When the handheld scrubber is parked in place, the handheld scrubber and the cleaning base station 2 as a whole can form an internal circulating water and gas system. When sewage needs to be discharged, the negative pressure motor 25 can be started first. The negative pressure motor 25 draws air in the sewage space 202 through the negative pressure air duct 251, thereby forming a negative pressure environment in the sewage space 202. After the negative pressure motor 25 is started for two seconds, a negative pressure environment is formed in the sewage space 202. At this time, the sewage discharge cover 132 can be controlled to be opened. The negative pressure sewage space 202 sequentially passes through the solid-liquid separation piece 204, the sewage inlet pipeline 205, the sewage inlet 211, the sewage outlet 131, and thereby communicates with the sewage tank 13, so that the dirt from the sewage tank 13 can flow against gravity in the sewage inlet pipeline 205 to the solid-liquid separation piece 204 under the action of negative pressure, and after solid-liquid separation, enters the sewage space 202, so as to be further treated by the cleaning base station 2.

[0098] Application scenario four

[0099] In the household cleaning scenario, the cleaning device 1 can be a handheld scrubber. When the handheld scrubber finishes cleaning the working surface, the user can park it on the cleaning base station 2, so as to perform self-cleaning. The position corresponding to the roller brush 112 on the tray 22 can be provided with a roller brush groove, thereby used for receiving the dirt on the roller brush 112, and the roller brush 112 can be self-cleaned in the roller brush groove.

[0100] The handheld scrubber is provided with a throat pipe 15. The throat pipe 15 is located at one end of the floor brush assembly 11 and is configured to communicate to the sewage suction port. The sewage suction port can face the roller brush groove, so that the dirt generated by the self-cleaning of the roller brush 112 can enter the throat pipe 15 through the sewage suction port. The throat pipe 15 is located at one end of the machine body 12 and communicates to the sewage tank 13, so as to be able to transport the dirt from the sewage suction port to the sewage tank 13.

[0101] When the handheld scrubber is parked in place, the handheld scrubber and the cleaning base station 2 as a whole can form an internal circulating water and gas system. When the roller brush 112 finishes self-cleaning, the negative pressure motor 25 can be started first. The negative pressure motor 25 draws air in the sewage space 202 through the negative pressure air duct 251, thereby forming a negative pressure environment in the sewage space 202. The sewage space 202 communicates with the sewage tank 13 through the sewage inlet pipeline 205, and the sewage tank 13 communicates with the roller brush groove through the throat pipe 15, so that the dirt generated by the self-cleaning of the roller brush 112 can flow against gravity in sequence through the throat pipe 15, the sewage tank 13, the sewage inlet pipeline 205, and finally flow into the sewage space 202, so as to be further treated by the cleaning base station 2.

[0102] Application scenario five

[0103] In the household cleaning scenario, the cleaning device 1 can be a handheld scrubber. After the handheld scrubber finishes cleaning the working surface, the user can park it on the cleaning base station 2 for self-cleaning. The wet rolling brush 112 after self-cleaning is prone to bacterial growth and odor generation, and therefore needs to be dried.

[0104] The drying air duct 252 is arranged on the base body 20, and can be arranged at a position below the negative pressure motor 25. One end of the drying air duct 252 is in communication with the air outlet of the negative pressure motor 25, and the other end is configured to extend to a position corresponding to the rolling brush 112 of the floor brush assembly 11. A heating element 26 is arranged in the drying air duct 252. The negative pressure motor 25 will discharge exhaust gas from the air outlet during the process of drawing air from the sewage space 202, and the exhaust gas is introduced into the drying air duct 252 and heated by the heating element 26, such as a PTC, to form hot air. The hot air can be blown to the rolling brush 112 to dry the wet rolling brush 112 after working or self-cleaning.

[0105] The present disclosure realizes gas recycling in the internal circulation system formed by the handheld scrubber and the cleaning base station 2 through one negative pressure motor 25, which forms a negative pressure environment in the sewage space 202 and also uses the drawn gas to dry the rolling brush 112. The dried rolling brush 112 is less prone to bacterial growth and odor generation, and improves the user experience.
