DETAILED DESCRIPTION

[0058] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0059] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0060] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0061] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0062] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0063] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the premise of each other's existence.

[0064] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0065] The present disclosure provides a cleaning system that can be applied to household or commercial cleaning scenarios. The cleaning system includes a cleaning device for cleaning a work surface and a base station for docking the cleaning device. The cleaning device can be a handheld cleaning device, such as a handheld cleaning machine, a handheld vacuum cleaner, a handheld floor scrubber, and other handheld cleaning devices well known to those skilled in the art; it can also be a self-moving cleaning robot such as a sweeping robot, a mopping robot, a sweeping and mopping robot, etc., which is used to clean the work surfaces that need to be cleaned, such as the floor, sofa, carpet, etc. The cleaning device is provided with a roller for cleaning the work surface, the surface of the roller can be attached with water, and it contacts with the work surface to be cleaned, thereby completing the mopping cleaning work. After the cleaning device finishes the cleaning work, it needs to enter the base station for maintenance, and the maintenance may include: charging, dust collection, sewage discharge, etc.

[0066] The base station includes a base and a self-cleaning component, wherein a cleaning tank is provided on the base, and the cleaning tank is configured to receive a cleaning element of a cleaning device, specifically, a drum, and the cleaning tank can cooperate with the drum to receive dirt for maintaining the cleaning device. When the cleaning device is placed in the base station, the drum is configured to be located above the cleaning tank, and dirt thrown off by the drum during cleaning will fall into the cleaning tank under the action of gravity, thereby preventing pollution of the environment outside the base station.

[0067] In the prior art, users need to regularly remove the cleaning tank to manually clean the dirt in the cleaning tank to maintain the clean and tidy appearance of the base station, but the manual cleaning method is very troublesome and greatly affects the user experience. In order to solve the above problems, the present disclosure provides a base station with a self-cleaning component, specifically, the cleaning tank is provided with a sewage discharge area. The self-cleaning component is constructed to be movably connected to the base, and is configured to move along a first direction and a second direction under the action of an external force, wherein the first direction and the second direction can be the extension direction of the cleaning tank, and the first direction and the second direction are opposite in direction; in the process of moving in the first direction, the self-cleaning component approaches the sewage discharge area and scrapes the cleaning tank to push the dirt to the sewage discharge area for discharge; in the process of moving in the second direction, the self-cleaning component moves away from the sewage discharge area and detaches from the surface to be cleaned of the cleaning tank.

[0068] In the present disclosure, the sewage discharge area is set at one end of the cleaning tank, and the self-cleaning component can move to the location of the sewage discharge area. Under the action of external force, the self-cleaning component can move in a first direction relative to the cleaning tank and transport the dirt in the cleaning tank to the sewage discharge area, so that there is no dirt residue on the surface of the cleaning tank, and the user no longer needs to clean the cleaning tank manually.

[0069] During the movement of the self-cleaning component in the second direction, the self-cleaning component is separated from the surface to be cleaned of the cleaning tank, thereby preventing the dirt in the sewage discharge area from being transported to other locations in the cleaning tank during the movement in the direction away from the sewage discharge area. It should be noted that the self-cleaning component does not need to be separated from the surface to be cleaned throughout the movement in the second direction. At some moments, the self-cleaning component can come into contact with the surface to be cleaned, as long as it is ensured that the self-cleaning component does not continuously scrape the surface to be cleaned.

[0070] The present invention realizes automatic cleaning of the cleaning tank by setting a self-cleaning component that is movably connected to the base. A sewage discharge area is set in the cleaning tank, and the sewage discharge area can be set at one end of the cleaning tank, and the self-cleaning component can move to the location of the sewage discharge area. The self-cleaning component can move in a first direction under the action of an external force, so as to transport the dirt in the cleaning tank to the sewage discharge area; in the process of moving in the second direction, the self-cleaning component is separated from the surface to be cleaned of the cleaning tank, so as to avoid scraping the dirt back from the sewage discharge area and avoid pushing the dirt to both ends. In this way, only the sewage discharge area needs to be set at one end, which reduces the cost. The user only needs to clean one end of the cleaning tank, which is convenient for maintenance and improves the sewage discharge effect. The user no longer needs to clean the cleaning tank manually, and can automatically maintain the cleanliness of the cleaning tank by relying solely on the self-cleaning component, thereby improving the user experience.

[0071] The specific embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0072] refer to Figure 1 and Figure 2 The present disclosure provides a cleaning system, including a cleaning device for cleaning a work surface and a base station 10 for docking the cleaning device. The cleaning device in this embodiment may be a sweeping and mopping robot. After completing the cleaning work, the sweeping and mopping robot can dock at Figure 1 The base station 10 shown is used for maintenance work such as charging, dust collection, and sewage discharge.

[0073] like Figure 2 As shown, the cleaning device is provided with a cleaning element for cleaning the working surface. In a specific embodiment of the present disclosure, the cleaning element may be a roller 21. The surface of the roller 21 may be attached with water and contact the working surface to be cleaned, thereby completing the mopping cleaning work. Specifically, a cleaning layer may be provided on the surface of the roller 21. The cleaning layer may be a sponge, cotton cloth, fluff, etc. During the rolling process, the cleaning layer may wipe the working surface and adhere to dust and other stains on the working surface. The surface of the roller 21 in this embodiment is provided with fluff.

[0074] like Figure 1As shown, the base station 10 includes: a body 11, a base 12 and a self-cleaning component 13, wherein the body 11 may be provided with components such as a clean water bucket, a dirty water bucket, a dust collection chamber, and a dust collection pipe, so that the base station 10 has a complete maintenance function. The base 12 is located below the body 11 and forms a receiving chamber with the body 11. After the cleaning work is completed, the sweeping and mopping robot can automatically drive to the receiving chamber and dock on the base 12.

[0075] In one embodiment of the present disclosure, reference Figure 2 The base 12 includes a climbing member 122 extending outward from the opening end of the accommodating cavity. The outer end of the climbing member 122 extends to the ground, and its surface is configured as an inclined surface. The sweeping and mopping robot can travel on the climbing member 122, so as to dock in the base station 10. The base 12 also includes two wheel grooves 125 spaced apart on both sides. When the sweeping and mopping robot docks in the base station 10, the two wheel grooves 125 can respectively accommodate the two driving wheels of the robot, so that the sweeping and mopping robot can dock in place stably and accurately.

[0076] In one embodiment of the present disclosure, a dust collection port 123 may also be provided on the base 12, and the dust collection port 123 is configured to be compatible with the dust discharge port of the sweeping and mopping robot. When the robot is docked in the base station 10, its dust discharge port can be connected to the dust collection port 123 on the base 12, and the base station 10 can collect the garbage collected by the sweeping and mopping robot to the base station 10.

[0077] like Figure 2 As shown, a cleaning tank 121 is provided on the base 12, and the cleaning tank 121 is configured to receive the cleaning element of the cleaning device, that is, to cooperate with the roller 21 of the cleaning device to receive the dirt of the maintenance cleaning device. When the sweeping and mopping robot is docked in the base station 10, its roller 21 is configured to be located above the cleaning tank 121, and the roller 21 will rotate along its axial direction during cleaning to shake off the dirt attached to its surface; in addition, the roller 21 can be flushed with clean water to flush the dirt away from the roller 21. The dirt separated from the roller 21 will fall into the cleaning tank 121 under the action of gravity, thereby preventing the environment outside the base station 10 from being polluted.

[0078] In one embodiment of the present disclosure, reference Figure 3 A water retaining edge 128 is arranged on the outside of the cleaning tank 121. The water retaining edge 128 can be a soft rubber flange with a certain height. When the drum 21 is cleaning, the dirt falling into the cleaning tank 121 will splash. The water retaining edge 128 can effectively prevent the dirt from splashing to places outside the cleaning tank 121, thereby maintaining environmental hygiene.

[0079] In the prior art, the user needs to regularly remove the cleaning tank 121 and manually clean the dirt in the cleaning tank 121 to maintain the clean and tidy appearance of the base station 10, but the manual cleaning method is very troublesome and greatly affects the user experience. Figure 1 As shown, the present disclosure provides a base station 10 with a self-cleaning component 13. Specifically, the cleaning tank 121 is provided with a sewage discharge area 124. It is defined that the first direction and the second direction extend along the extension direction of the cleaning tank 121, and the first direction and the second direction are opposite, as shown in FIG. Figure 3 As shown, the direction indicated by the x-axis is the first direction, and the direction indicated by the x'-axis is the second direction.

[0080] The self-cleaning component 13 is configured to be movably connected to the base 12, and is configured to move in a first direction and a second direction under the action of an external force; the detection component is used to detect the movement of the self-cleaning component 13, and the detection component is electrically connected to the control component of the cleaning system to feed back the movement information of the self-cleaning component 13 to the control component. In the process of moving in the first direction, the self-cleaning component 13 approaches the sewage discharge area 124, and scrapes the cleaning tank 121 to push the dirt to the sewage discharge area 124 for discharge; when the detection component detects that the self-cleaning component 13 is moving in the second direction, the self-cleaning component 13 is away from the sewage discharge area 124, and the control component controls the self-cleaning component 13 to separate from the surface to be cleaned of the cleaning tank 121. Under the action of an external force, the self-cleaning component 13 can move in the first direction relative to the cleaning tank 121, and transport the dirt in the cleaning tank 121 to the sewage discharge area 124, so that there is no dirt residue on the surface of the cleaning tank 121, and the user no longer needs to manually clean the cleaning tank 121.

[0081] The detection component can obtain the movement direction of the self-cleaning component 13. Specifically, the detection component can be a sensor arranged on the self-cleaning component 13, so as to directly obtain its movement direction. The detection component can also obtain the movement direction of the self-cleaning component 13 in other indirect ways. For example, in a specific embodiment of the present disclosure, the self-cleaning component 13 can be driven to move in the first direction and the second direction by the forward rotation and reverse rotation of the drum 21. At this time, the detection component can be a detection circuit in the motor that drives the drum 21 to rotate. The detection circuit can obtain the rotation direction of the drum 21 by receiving the forward rotation signal or reverse rotation signal of the motor, thereby obtaining the movement direction of the self-cleaning component 13.

[0082] Further, the control component can control the self-cleaning component 13 to separate from the surface to be cleaned of the cleaning tank 121 based on the signal obtained by the detection component that the self-cleaning component 13 moves in the second direction. In a specific embodiment of the present disclosure, the structure on the self-cleaning component 13 that is used to contact the surface to be cleaned of the cleaning tank 121 can be lifted under the action of friction, so the parameters of the motor that drives the roller 21 to rotate can be controlled to change, and the parameters of the motor may include torque, frequency, voltage, speed, etc.; by controlling the change of the motor parameters, the roller 21 can be accelerated suddenly, so that the friction force on the structure on the self-cleaning component 13 that is used to contact the surface to be cleaned of the cleaning tank 121 suddenly increases, thereby prompting the self-cleaning component 13 to separate from the surface to be cleaned of the cleaning tank 121. In other embodiments, the control component can also control the self-cleaning component 13 to separate from the surface to be cleaned of the cleaning tank 121 in other forms, for example, a structure for lifting the self-cleaning component 13 can be directly set, and the present disclosure does not specifically limit this.

[0083] Further, based on the above cleaning system, the present application also provides a control method of the cleaning system, which comprises: after the cleaning device enters the base station, the control component of the cleaning system controls the self-cleaning component to clean the cleaning element;

[0084] The detection component detects the moving direction of the self-cleaning component, and when it is detected that the self-cleaning component 13 is moving in the second direction, the self-cleaning component 13 is away from the sewage discharge area 124, and the control component controls the self-cleaning component 13 to be separated from the surface to be cleaned of the cleaning tank 121. Thus, the cleaning element is automatically cleaned, and the dirt scraped off will not be concentrated in the direction away from the sewage discharge area, thereby ensuring the cleaning efficiency of the surface to be cleaned of the cleaning tank 121.

[0085] In one embodiment of the present disclosure, Figure 3 As shown, the two ends of the length direction of the cleaning tank 121 are respectively recorded as the first end and the second end. When the self-cleaning component 13 moves along the first direction shown by the x-axis, the self-cleaning component 13 moves from the first end to the second end of the cleaning tank 121; when the self-cleaning component 13 moves along the second direction shown by the x' axis, the self-cleaning component 13 moves from the second end to the first end of the cleaning tank 121. The sewage discharge area 124 can be set at the second end of the cleaning tank 121.

[0086] refer to Figure 2The sewage discharge area 124 may include a filter screen and a sewage holding area, wherein the filter screen may be configured to be detachably covered above the sewage holding area and configured to be at the same height as the inner surface of the cleaning tank 121; the sewage holding area may be connected to the sewage tank in the machine body 11 through the sewage suction pipe 126. When the dirt is sent to the sewage discharge area 124 by the self-cleaning component 13, liquid dirt such as sewage can enter the sewage holding area through the filter screen and be sucked into the sewage tank in the machine body 11 by the sewage suction pipe 126, thereby achieving sewage discharge.

[0087] Large particles of solid dirt, hair, etc. will remain on the top of the filter. After a certain amount of dirt is collected, the user can remove the filter for cleaning. The filter is provided to achieve dry and wet separation of dirt and prevent large particles of matter from clogging the suction pipe 126. It is understandable that solid dirt is mainly cleaned by the sweeping and suction functions of the sweeping and mopping robot, and only a small amount of residual garbage will stick to the drum 21 and fall into the cleaning tank 121. After a long period of accumulation, a certain amount of dirt will be collected on the filter, that is, the user may need to clean the filter only after a long period of time. Moreover, the solid garbage that has achieved dry and wet separation is not easy to produce odor even if it is left for a long time. Compared with the solution that requires frequent manual cleaning of the cleaning tank 121, the present disclosure greatly improves the user experience by providing a self-cleaning component 13 and a dry and wet separation sewage discharge area 124.

[0088] During the movement of the self-cleaning component 13 in the second direction, the self-cleaning component 13 is separated from the surface to be cleaned of the cleaning tank 121, thereby preventing the dirt in the sewage discharge area 124 from being transported to other positions in the cleaning tank 121 during the movement in the direction away from the sewage discharge area 124. It should be noted that the self-cleaning component 13 does not need to be separated from the surface to be cleaned throughout the movement in the second direction. At some moments, the self-cleaning component 13 can come into contact with the surface to be cleaned, as long as it is ensured that the self-cleaning component 13 does not continuously scrape the surface to be cleaned.

[0089] The present disclosure realizes automatic cleaning of the cleaning tank 121 by setting a self-cleaning component 13 that is movably connected to the base 12. A sewage discharge area 124 is set in the cleaning tank 121, and the sewage discharge area 124 can be set at one end of the cleaning tank 121. The self-cleaning component 13 can move to the location of the sewage discharge area 124. The self-cleaning component 13 can move in a first direction under the action of an external force, so as to transport the dirt in the cleaning tank 121 to the sewage discharge area 124; in the process of moving in the second direction, the self-cleaning component 13 is separated from the surface to be cleaned of the cleaning tank 121, so as to avoid scraping the dirt back from the sewage discharge area 124, and avoid pushing the dirt to both ends. In this way, only the sewage discharge area 124 needs to be set at one end, which reduces the cost. The user only needs to clean one end of the cleaning tank 121, which is convenient for maintenance and improves the sewage discharge effect. The user no longer needs to manually clean the cleaning tank 121, and can automatically maintain the cleanliness of the cleaning tank 121 by relying solely on the self-cleaning component 13, thereby improving the user experience.

[0090] In one embodiment of the present disclosure, the drum 21 has a first rotation direction and a second rotation direction corresponding to the first direction and the second direction, respectively. When the drum 21 rotates along the first rotation direction, the self-cleaning assembly 13 is configured to move from the first end of the cleaning tank 121 to the second end under the force of the drum, that is, to move in the first direction; when the drum 21 rotates along the second rotation direction, the self-cleaning assembly 13 is configured to move from the second end of the cleaning tank 121 to the first end under the force of the drum, that is, to move in the second direction. The self-cleaning assembly 13 can move along the extension direction of the cleaning tank 121 under the rotation of the drum 21, so that there is no need to provide additional power for the movement of the self-cleaning assembly 13. It is understandable that the drum 21 will execute the cleaning program during normal operation, and the program setting usually includes multiple forward and reverse rotations. The drum 21 can rotate along the first rotation direction and the second rotation direction under program control. The drum 21 can achieve self-cleaning by rotating, and can also drive the self-cleaning assembly 13 to move along the extension direction of the cleaning tank 121, thereby realizing automatic cleaning of the cleaning tank 121.

[0091] Specifically, the self-cleaning assembly 13 includes a cleaning portion and a matching portion disposed on the cleaning portion, and the matching portion is configured to contact and match with the drum 21. The matching portion is configured to drive the cleaning portion to move between the first end and the second end of the cleaning tank 121 under the action of the rotational torque of the drum 21. The self-cleaning assembly 13 can move along the extension direction of the cleaning tank 121 under the action of the rotational force of the drum 21.

[0092] like Figure 2As shown, the extension direction of the cleaning groove 121 is the axial direction of the drum 21, that is, the matching portion can convert the torque of the drum 21 into an axial force, so that the self-cleaning assembly 13 as a whole moves along the extension direction of the cleaning groove 121. In order to achieve the force conversion, the present disclosure provides two specific implementations, and two different structural designs are made for the matching portion, which will be described in detail below.

[0093] In a specific embodiment of the present disclosure, reference Figures 3 to 6 The matching part is a driving seat 134 disposed on the cleaning part, and a driving member 1341 extending obliquely is disposed on the surface of the driving seat 134 for matching with the roller 21. The driving member 1341 is configured to convert the torque when the roller 21 rotates along the first rotation direction into a first axial force moving toward the second end of the cleaning tank 121, and to convert the torque when the roller 21 rotates along the second rotation direction into a second axial force moving toward the first end of the cleaning tank 121.

[0094] Specifically, Figure 4 As shown, the driving member 1341 is a convex structure and / or a concave structure at least arranged on the surface of the driving seat 134, and the convex structure and / or the concave structure is configured to be arranged at an angle with the rotation axis of the drum 21. The driving member 1341 in this embodiment is a plurality of convex rib structures arranged at intervals, and the convex rib structures can extend into the fluff of the drum 21, so that the surface of the driving seat 134 and the drum 21 form an interference fit.

[0095] refer to Figure 6 When the drum 21 rotates in the first rotation direction, the part that cooperates with the driving member 1341 will continue to apply a resultant force F1 to the rib. The resultant force F1 may include the pressure of the positive torque of the drum 21 acting on the driving member 1341, and may also include the sliding friction generated during the rotation process. The direction of F1 is perpendicular to the driving member 1341. Since F1 can be decomposed into a first axial force Fa1 in the x-axis direction and a small part of the first component force Ft1 perpendicular to the x-axis direction, the self-cleaning component 13 is constructed to move only in the first direction, that is, only in the x-axis direction. Figure 6 That is, during the process of the drum 21 rotating along the first rotation direction, the self-cleaning assembly 13 is subjected to the first axial force Fa1, and thus can move along the first direction.

[0096] Continue to refer Figure 6When the drum 21 rotates in the second rotation direction, the part cooperating with the driving member 1341 will continue to apply a resultant force F2 to the convex rib. The resultant force F2 may include the pressure of the reverse torque of the drum 21 acting on the driving member 1341, and may also include the sliding friction generated during the rotation process. The direction of F2 is perpendicular to the driving member 1341 and opposite to the direction of the resultant force F1. Since F2 can be decomposed into a second axial force Fa2 toward the x'-axis direction, and a small part of the second component force Ft2 perpendicular to the x-axis direction, the self-cleaning component 13 is constructed to move only in the second direction shown by the x'-axis. In other words, during the process of the drum 21 rotating in the second rotation direction, the self-cleaning component 13 is subjected to the second axial force Fa2, and is therefore able to move in the second direction.

[0097] It should be noted that the present disclosure does not specifically limit the angle between the driving member 1341 and the rotation axis of the drum 21. As long as the angle is not 0° or 90°, force conversion can be achieved. However, if the angle is set too small, the first axial force Fa1 or the second axial force Fa2 obtained by conversion may be too small to overcome the static friction between the self-cleaning component 13 and the base 12. Therefore, it is necessary to set the inclination angle of the driving member 1341 according to the actual application situation to maximize the conversion efficiency.

[0098] Furthermore, the driving member 1341, as a rib structure, will continue to scrape the surface of the drum 21 during its movement, thereby scraping the dirt remaining on the drum 21 into the cleaning tank 121. This improves the efficiency and strength of the self-cleaning of the drum 21. The driving member 1341 can not only drive the self-cleaning component 13 to move, but also assist the drum 21 in cleaning.

[0099] In one embodiment of the present disclosure, reference Fig. 9 , a toggle portion is provided on the drum 21, and the toggle portion is configured to cooperate with the driving member 1341 during the rotation of the drum to provide a first axial force or a second axial force for the cleaning portion to move in the extension direction of the cleaning tank 121. Specifically, the toggle portion is a plurality of toggle protrusions 211 extending in the axial direction of the drum 21, and the toggle protrusions 211 are configured not to exceed the fluff on the drum 21. The toggle protrusions 211 can increase the friction between the drum 21 and the driving seat 134, thereby improving the efficiency of self-cleaning. The toggle protrusions 211 can extend between the driving members 1341, and during the movement of the self-cleaning assembly 13, the toggle protrusions 211 can form a match between the side walls of the driving member 1341, thereby enhancing the force of the drum 21 on the driving seat 134. The gap between adjacent toggle protrusions 211 can be configured to be 2-3 times the gap between adjacent driving members 1341, so that the self-cleaning assembly 13 has a more appropriate running speed. Fig. 9Only one row of the moving protrusions 211 on the surface of the drum 21 is shown in cross section. In actual application, multiple rows of the moving protrusions 211 can be arranged around the drum 21.

[0100] It should be noted that the structure of the toggle protrusion 211 is short and will not exceed the height of the fluff on the drum 21, and can only form a certain cooperation with the driving member 1341 extending into the fluff. In the normal cleaning process, the toggle protrusion 211 basically does not touch the working surface and will not affect the normal cleaning work.

[0101] In one embodiment of the present disclosure, continue to refer to Fig. 9 In the axial direction of the drum 21, the drum 21 includes a power zone 22 located in the middle area and a non-power zone 23 located at opposite ends of the power zone 22; wherein the driving member 1341 is configured to be disengaged from the toggle portion when it moves to a position that cooperates with the non-power zone 23; the driving member 1341 is configured to move from the non-power zone 23 to cooperate with the toggle portion of the power zone 22 under the cooperation of the fluff of the drum 21. Fig. 9 As shown, no actuating protrusions 211 are provided on both sides of the drum 21 , thereby forming a non-powered area 23 on both sides of the drum 21 ; and a actuating protrusions 211 are provided in the middle area, thereby forming a powered area 22 .

[0102] Under the action of the rotational force of the drum 21, the self-cleaning component 13 can move along the axial direction of the drum 21 to the edge position at one end of the cleaning tank 121. At this time, the drum 21 will usually continue to maintain the current rotation state, but the self-cleaning component 13 can no longer move. Therefore, it is necessary to ensure that when the self-cleaning component 13 runs to the edge position, the drum 21 will not be stuck due to the action of the self-cleaning component 13. To this end, the present embodiment only provides a toggle protrusion 211 in the middle area of ​​the drum 21, forming a power zone 22 with very high transmission efficiency; and no toggle protrusion 211 is provided on both sides of the drum 21 to prevent the driving member 1341 on the self-cleaning component 13 that moves to the edge from being stuck with the toggle protrusion 211.

[0103] For example, refer to Figure 3 and Fig. 9 , the self-cleaning component 13 is located at the initial state Figure 3 At this time, the drive seat 134 cooperates with the power area 22 on the drum 21, and the drum 21 rotates along the first rotation direction to make the self-cleaning assembly 13 move along the first direction to transport the dirt to the sewage discharge area 124. When the self-cleaning assembly 13 runs to the edge of the cleaning tank 121, that is, it is located at Fig. 9When the self-cleaning component 13 is in the position drawn by the dotted line, the drive seat 134 cooperates with the unpowered area 23 on the drum 21, and the drum 21 can continue to rotate in the first rotation direction for cleaning. When the drum 21 completes the forward rotation this time and starts to execute the next reversal procedure, under the friction of the interference fit of the fluff, the drive seat 134 converts the reverse torque into a second axial force moving in the second direction, thereby causing the self-cleaning component 13 to move in the second direction. When the self-cleaning component 13 moves to a position that cooperates with the power area 22 on the drum 21, the push protrusion 211 cooperates with the drive member 1341, thereby enhancing the force of the drum 21 on the drive seat 134. When the self-cleaning component 13 continues to move in the second direction until it reaches the edge position on the other side of the cleaning tank 121, that is, it is located Fig. 9 When the self-cleaning assembly 13 is at the position indicated by the solid line, the driving seat 134 cooperates with the unpowered area 23 on the drum 21, and the drum 21 can continue to rotate along the second rotation direction.

[0104] The above description is a specific implementation of the matching portion being the driving seat 134. The present disclosure also provides another completely different matching portion structure, which can also achieve force conversion, and this will be described in detail below.

[0105] In a specific embodiment of the present disclosure, reference Figures 10 to 13 The matching part is a wheel set 135 rotatably connected to the cleaning part, and the wheel set 135 includes a driving wheel and a running wheel 1356 drivingly connected to the driving wheel. The driving wheel is used to contact and match with the drum 21, and is configured to be controlled by the rotation of the drum 21, and the running wheel 1356 is configured to be controlled by the rotation of the driving wheel to drive the cleaning part to move between the first end and the second end of the cleaning tank 121. Specifically, as Fig.12 As shown, the wheel set 135 further includes a transmission wheel 1354 meshed with the driving wheel, and the transmission wheel 1354 and the walking wheel 1356 are constructed to be connected together through a rotating shaft 1355 to achieve coaxial rotation.

[0106] The driving wheel and the transmission wheel 1354 may have different rotation directions. Specifically, the rotation axis of the driving wheel may be consistent with the drum 21, while the rotation axes of the transmission wheel 1354, the rotation shaft 1355 and the walking wheel 1356 are perpendicular to the rotation axis of the drum 21. The driving wheel may be provided with a connecting portion 1353, and the surface of the connecting portion 1353 is provided with densely arranged threads. The teeth of the transmission wheel 1354 may be meshed with the above-mentioned threads, thereby achieving the change of the rotation direction.

[0107] Specifically, the driving wheel is used to contact and cooperate with the drum 21, and can rotate in the opposite direction to the drum 21, and the connecting portion 1353 also keeps the opposite rotation direction to the drum 21. At this time, the transmission wheel 1354 rolls relatively along the surface of the connecting portion 1353 under the driving action of the connecting portion 1353, that is, rotates in a direction perpendicular to the rotation axis of the drum 21. Under the driving action of the rotating shaft 1355, the two walking wheels 1356 arranged at both ends of the rotating shaft 1355 can rotate with the transmission wheel 1354, thereby driving the cleaning part to move along the extension direction of the cleaning tank 121.

[0108] In one embodiment of the present disclosure, reference Fig.11 The cleaning part is slidably fitted on the base 12, and a rack 129 meshing with the running wheel 1356 is provided on the base 12, and the running wheel 1356 is configured to run along the rack 129 during the rotation process. Racks 129 are respectively provided on both sides of the base 12 in the width direction, and two running wheels 1356 provided at both ends of the rotating shaft 1355 are respectively meshed on the two racks 129. When the running wheel 1356 rotates, that is, it runs along the rack 129, so that the self-cleaning component 13 can be driven to move relative to the base 12 as a whole.

[0109] In one embodiment of the present disclosure, reference Fig.13 and Fig.15 The driving wheels include a first driving wheel 1351 and a second driving wheel 1352 that are spaced apart in the first direction and the second direction; the cleaning portion is configured to be able to move in the first direction to a position where the first driving wheel 1351 is disengaged from the drum 21 and the second driving wheel 1352 is kept in cooperation with the drum 21; and to be able to move in the second direction to a position where the second driving wheel 1352 is disengaged from the drum 21 and the first driving wheel 1351 is kept in cooperation with the drum 21.

[0110] like Fig.13 As shown, the first driving wheel 1351 and the second driving wheel 1352 can be two gears respectively arranged on both sides of the connecting portion 1353. When the self-cleaning assembly 13 is located in the middle of the drum 21, the first driving wheel 1351 and the second driving wheel 1352 can cooperate with the surface of the drum 21 at the same time and drive the self-cleaning assembly 13 to move in the first direction or the second direction at the same time. Fig.15 As shown, when the drum 21 rotates along the α direction, that is, it rotates forward along the first rotation direction, the self-cleaning component 13 moves along the first direction; when the drum 21 rotates along the β direction, that is, it rotates reversely along the second rotation direction, the self-cleaning component 13 moves along the second direction.

[0111] In actual application scenarios, the drum 21 will not stop rotating or reverse rotating after the self-cleaning assembly 13 reaches the edge, but will usually continue to maintain the current rotation state. When the self-cleaning assembly 13 moves to the edge position of the second end of the cleaning tank 121 under the continuous forward rotation of the drum 21, that is, it runs to Fig.15 In the state shown, the first driving wheel 1351 is disengaged from the drum 21, and the second driving wheel 1352 is kept in cooperation with the drum 21, so that the resistance faced by the drum 21 when it continues to rotate forward can be reduced. At this time, only the second driving wheel 1352 is in contact with the drum 21. Compared with the state in which both driving wheels are in contact, the interaction force between the drum 21 and the self-cleaning assembly 13 is greatly reduced, thereby avoiding the situation in which the drum 21 is stuck due to excessive resistance.

[0112] Similarly, when the self-cleaning component 13 moves to the edge of the first end of the cleaning tank 121 under the action of the continuous reversal of the drum 21, the second driving wheel 1352 disengages from the drum 21 and the first driving wheel 1351 maintains a matched position with the drum 21, thereby reducing the resistance faced by the drum 21 when it continues to reverse, thereby avoiding the situation where the drum 21 is stuck due to excessive resistance.

[0113] In one embodiment of the present disclosure, reference Fig.13 The first driving wheel 1351 is provided with a first matching piece 13511 tilted in the radial direction, and the second driving wheel 1352 is provided with a second matching piece 13521 tilted in the radial direction, and the first matching piece 13511 and the second matching piece 13521 are tilted in opposite directions. When the drum 21 rotates along the first rotation direction, the friction force between the drum 21 and the first matching piece 13511 is greater than the friction force between the drum 21 and the second matching piece 13521; when the drum 21 rotates along the second rotation direction, the friction force between the drum 21 and the second matching piece 13521 is greater than the friction force between the drum 21 and the first matching piece 13511.

[0114] refer to Fig.15 , the first matching piece 13511 on the first driving wheel 1351 is inclined in the radial direction toward the α direction, that is, inclined toward the first rotation direction of the drum 21; the second matching piece 13521 on the second driving wheel 1352 is inclined in the radial direction toward the β direction, that is, inclined toward the second rotation direction of the drum 21. It should be noted that the inclination angles of the first matching piece 13511 and the second matching piece 13521 should not be too large, otherwise it will affect the matching effect between the first driving wheel 1351, the second driving wheel 1352 and the surface of the drum 21.

[0115] The first matching piece 13511 is inclined toward the forward rotation direction of the drum 21, so that it can provide a larger friction force when the drum 21 rotates along the first rotation direction, and can provide a smaller friction force when the drum 21 rotates along the second rotation direction; the second matching piece 13521 is inclined toward the reverse rotation direction of the drum 21, so that it can provide a larger friction force when the drum 21 rotates along the second rotation direction, and can provide a larger friction force when the drum 21 rotates along the first rotation direction.

[0116] refer to Fig.15 When the self-cleaning component 13 moves to the edge of the second end of the cleaning tank 121 under the continuous forward rotation of the drum 21, the first driving wheel 1351 providing a larger friction force disengages from the drum 21, and only the second driving wheel 1352 providing a smaller friction force remains in contact with the drum 21. That is to say, at this time, the drum 21 will only be subject to very small resistance, which will not affect its continued rotation along the first rotation direction at all.

[0117] When the drum 21 starts to reverse, the second drive wheel 1352 can provide a larger friction force, which is sufficient to drive the self-cleaning assembly 13 as a whole to move in the second direction. When the self-cleaning assembly 13 moves to a position where both the first drive wheel 1351 and the second drive wheel 1352 are in contact with the surface of the drum 21, the maximum driving force can be achieved. When the self-cleaning assembly 13 moves to the edge of the first end of the cleaning tank 121 under the continuous reversal of the drum, the second drive wheel 1352 that provides a larger friction force is separated from the drum 21, and only the first drive wheel 1351 that provides a smaller friction force is retained to contact and cooperate with the drum. At this time, the drum 21 will only be subject to very small resistance, which will not affect its continued rotation in the second rotation direction at all.

[0118] The above description is a specific implementation of the matching part being the wheel set 135. The two different matching part structures provided by the present disclosure have been introduced, and other structural features of the self-cleaning component 13 will be introduced in detail below.

[0119] In one embodiment of the present disclosure, reference Figures 3 to 5 The cleaning part includes a mounting bracket 131, and the mounting bracket 131 is configured to be movably connected to the base 12. Figure 5 As shown, a cleaning member 132 is provided on one side of the mounting bracket 131 facing the cleaning tank 121, and the cleaning member 132 is configured to cooperate with at least a portion of the surface to be cleaned of the cleaning tank 121, so as to clean the dirt on the surface to be cleaned when the mounting bracket 131 moves in the first direction. The cleaning member 132 may be a rubber scraper, and the bottom of the cleaning member 132 may cooperate with at least a portion of the surface to be cleaned of the cleaning tank 121. When the self-cleaning assembly 13 moves along the cleaning tank 121 in the first direction, the cleaning member 132 can scrape the dirt in the cleaning tank 121, thereby transporting the dirt to the sewage discharge area 124 for treatment.

[0120] Furthermore, the mounting bracket 131 can be slidably connected to the base 12 via a pulley 1311. Figure 3 As shown, two sliding parts 120 extending along the length direction of the cleaning tank 121 are arranged at the base 12 on both sides of the cleaning tank 121 in the width direction, and the sliding parts 120 are constructed to be slightly higher than the step surface of the cleaning tank 121. Figure 5 As shown, the pulleys 1311 are arranged on opposite sides of the mounting bracket 131, and two pulleys 1311 may be arranged on each side. A circle of limiting edges 1312 is arranged on the inner end surface of each pulley 1311, and the limiting edges 1312 may be engaged with the edge of the step surface of the sliding portion 120, thereby ensuring smooth sliding and also ensuring that the mounting bracket 131 is not easy to fall off from the base 12. In addition, the limiting edges 1312 also ensure the balance of the mounting bracket 131, and prevent the deflection caused by the inconsistent displacement of the pulleys 1311 on both sides.

[0121] The driving seat 134 or the wheel set 135 is installed on the mounting bracket 131 as a matching part to contact and match with the drum 21, and drive the self-cleaning assembly 13 to move along the extension direction of the cleaning tank 121. When the drum 21 rotates forward, the pulley 1311 slides along the first direction relative to the sliding part 120, and the cleaning member 132 contacts and matches with the cleaning tank 121 to scrape the dirt to the sewage discharge area 124. When the drum 21 rotates reversely, the pulley 1311 slides along the second direction relative to the sliding part 120. At this time, if the cleaning member 132 still abuts against the cleaning tank 121, part of the dirt will be scraped back into the cleaning tank 121, which is not conducive to cleaning the cleaning tank 121. Therefore, it is necessary to further design the structure of the cleaning part so that the cleaning part can be separated from the cleaning surface of the cleaning tank 121 during the movement in the second direction.

[0122] In one embodiment of the present disclosure, the sewage discharge area 124 is disposed at the second end of the cleaning tank 121. Figure 7 and Figure 8 The cleaning member 132 is movably connected to the mounting bracket 131, wherein, when the mounting bracket 131 moves toward the sewage discharge area 124, the cleaning member 132 is constructed to be pre-pressed on the surface to be cleaned of the cleaning tank 121; when the mounting bracket 131 moves away from the sewage discharge area 124, the cleaning member 132 is constructed to have a tendency to separate from the cleaning tank 121 under the action of the friction force of the cleaning tank 121.

[0123] like Figure 7As shown, the self-cleaning assembly 13 at this time moves in the first direction as a whole, that is, in the direction where the sewage discharge area 124 is located. The cleaning member 132 is kept vertically to the bottom surface of the cleaning tank 121 as a whole, and is configured to be pre-pressed on the surface to be cleaned of the cleaning tank 121. In this way, the cleaning member 132 can play the role of transporting dirt, and the dirt in the cleaning tank 121 can be smoothly transported to the sewage discharge area 124 for treatment under the scraping action of the cleaning member 132.

[0124] like Figure 8 As shown, the self-cleaning assembly 13 at this time moves as a whole toward the second direction, that is, moves away from the direction where the sewage discharge area 124 is located. The cleaning member 132 is tilted as a whole relative to the bottom surface of the cleaning tank 121, and is configured to be separated from the surface to be cleaned of the cleaning tank 121. In this way, the cleaning member 132 can be prevented from scraping dirt from the sewage discharge area 124 back to the cleaning tank 121, and the dirt sent to the first direction during the forward rotation of the drum 21 can be left in the sewage discharge area 124 for processing, and will not be brought back to the second direction by the cleaning member 132 when the drum 21 starts to reverse. When the drum 21 rotates along the second rotation direction, the cleaning member 132 can be separated from the cleaning tank 121, or has a tendency to be separated from the cleaning tank 121, so that it does not play a scraping role during the movement in the second direction.

[0125] In a specific embodiment of the present disclosure, reference Figure 4 and Figure 5 , a mounting groove 1313 for mounting a cleaning member 132 is provided on the mounting bracket 131. The mounting groove 1313 can be provided at the bottom end of the mounting bracket 131, and is configured to penetrate the mounting bracket 131 along the axial direction of the mounting bracket 131. The cleaning member 132 is configured to be detachably mounted in the mounting groove 1313. The cleaning member 132 will wear out during long-term scraping, so in this embodiment, the cleaning member 132 is configured to be detachable. Specifically, the cross-section of the cleaning member 132 can be configured to be T-shaped, and the vertical structure at the bottom is used to scrape dirt, and the protruding structure at the upper part can be engaged in the mounting groove 1313 to prevent it from falling off. The cleaning member 132 can be disassembled very easily. The user only needs to insert the cleaning member 132 into the mounting groove 1313 from the notch on the side of the mounting bracket 131, and make the cleaning member 132 pass to the bottom between the two pulleys 1311 to achieve installation. The cleaning member 132 can be disassembled by pulling it outward along the axial direction of the mounting bracket 131.

[0126] refer to Figure 7 and Figure 8 A movable space 13131 for the cleaning member 132 to tilt is provided on one side of the mounting groove 1313 adjacent to the sewage discharge area 124. When the mounting bracket 131 moves in the second direction, the cleaning member 132 is configured to tilt toward the movable space 13131 under the action of friction. Figure 7 As shown, the cross section of the mounting groove 1313 is constructed to be approximately in the shape of a right-angled trapezoid, wherein the side close to the second direction is the short side, the side close to the first direction is the long side, the right-angled side is located at the bottom, and the hypotenuse is located at the top. Both the short side and the long side are constructed as arcs to facilitate the swing of the cleaning member 132 in the mounting groove 1313. The length of the short side is substantially consistent with the thickness of the protruding structure on the upper part of the cleaning member 132, and a limit is formed on one end of the protruding structure in the second direction, so that the cleaning member 132 can only swing with the end position of the protruding structure in the second direction as the center of the circle. The length of the long side is constructed to be greater than the thickness of the protruding structure on the upper part of the cleaning member 132, thereby forming an activity space 13131, and the cleaning member 132 can tilt toward the activity space 13131 to disengage from the cleaning tank 121.

[0127] like Figure 7 As shown, the cleaning member 132 is moving in the first direction, that is, in the direction of the sewage discharge area 124. The bottom of the cleaning member 132 is pre-pressed on the surface to be cleaned of the cleaning tank 121, and the cleaning member 132 is subjected to a sliding friction force in the second direction. Under the action of the friction force, the cleaning member 132 has a counterclockwise direction (refer to Figure 7 However, due to the limiting effect of the bottom of the installation groove 1313, the cleaning member 132 can only remain perpendicular to the bottom surface of the cleaning groove 121, thereby playing the role of transporting dirt. Under the scraping effect of the cleaning member 132, the dirt in the cleaning groove 121 can be smoothly transported to the sewage discharge area 124 for treatment.

[0128] like Figure 8 As shown in FIG. 1 , the cleaning member 132 is now moving in the second direction, that is, moving away from the direction where the sewage discharge area 124 is located. When the cleaning member 132 starts to move in the second direction, it has not yet tilted away from the bottom surface of the cleaning tank 121. At this time, the cleaning member 132 is subjected to a sliding friction force in the first direction. Under the action of the friction force, the cleaning member 132 has a clockwise direction (refer to FIG. 1 ). Figure 8 The cleaning member 132 can swing clockwise with the end position of the protruding structure in the second direction as the center of the circle, so as to tilt in the activity space 13131 to a position away from the bottom surface of the cleaning tank 121, so as not to play a scraping role during the movement in the second direction.

[0129] When there is a lot of dirt in the cleaning tank 121, it is easy for dirt to splash when the cleaning member 132 moves along the extension direction of the cleaning tank 121. In addition, when the dirt is quickly scraped by the cleaning member 132 to the sewage discharge area 124, it may not have time to leak through the filter screen to the sewage holding area, thereby causing the dirt to continue to be scraped to the edge of the cleaning tank 121 and squeezed out of the cleaning tank 121 by the cleaning member 132 that continues to move to the edge. In addition, when the self-cleaning component 13 moves away from the sewage discharge area 124, the cleaning member 132 may scrape some dirt and move together, which will cause dirt to accumulate on the side of the cleaning member 132 away from the sewage discharge area 124.

[0130] In order to cope with the above application scenarios, in one embodiment of the present disclosure, reference Fig.14 , a reflow area 127 is formed between the two opposite sides of the cleaning member 132 and the cleaning tank 121. When the cleaning member 132 moves in the second direction, the dirt in the cleaning tank 121 is configured to flow through the reflow area 127 toward the direction close to the sewage discharge area 124. Specifically, the reflow area 127 is a gap provided on both sides of the cleaning member 132, and the gap width is about 3-5 mm. The dirt can flow to the other side of the cleaning member 132 through the reflow area 127, thereby preventing the dirt from being squeezed out of the cleaning tank 121 by the cleaning member 132, and also preventing the dirt from accumulating on the side away from the sewage discharge area 124.

[0131] like Fig.14 As shown, the pulley 1311 is located on the sliding part 120 of the base 12. As mentioned above, the sliding part 120 is a step surface slightly higher than the cleaning tank 121. There is a gap between the inner side wall of the step surface and the side wall of the cleaning member 132, so that the reflow area 127 is formed on both sides of the cleaning member 132. Specifically, the bottom surface of the reflow area 127 is a slope surface, that is, the bottom surface of the cleaning tank 121 and the side wall of the step surface of the sliding part 120 are connected by the slope surface. In this way, the dirt passing through the reflow area 127 has a tendency to flow to the inside of the cleaning tank 121. It can be understood that the dirt passing through the reflow area 127 itself is located on both sides of the cleaning tank 121, and this is a cleaning dead corner that cannot be scraped by the cleaning member 132. Therefore, this embodiment sets a slope surface to ensure that no dirt will remain at the reflow area 127.

[0132] In actual application scenarios, the roller 21 is easily entangled with hair during the cleaning process. In the prior art, the user is usually required to manually clean the hair entangled on the roller 21, which is very inconvenient. In order to cope with the above application scenarios, in one embodiment of the present disclosure, reference Figure 4 and Fig.12The cleaning part is provided with a cutting part 133, which is configured to extend into the fluff of the drum 21 to cut foreign matter entangled on the surface of the drum 21 during movement. As a part of the self-cleaning assembly 13, the cutting part 133 can move along the extension direction of the cleaning tank 121, and the cutting part 133 can extend into the bristles of the drum 21 and cut off the hair entangled on the surface of the drum 21 during movement.

[0133] It is understandable that during the movement of the cutting portion 133, the drum 21 will rotate synchronously, and the hair wound on the drum 21 will also rotate accordingly. Since the hair is usually not wound very tightly, the hair has a tendency to be thrown outwards under the action of centrifugal force during the rotation of the drum 21, and is likely to be directly caught on the cutting portion 133 during the throwing process. Therefore, the cutting portion 133 does not need to extend too deeply into the hair of the drum 21, but only needs to be partially extended into the hair, so as to prevent the cutting portion 133 from directly contacting the inner surface of the drum 21, thereby preventing the drum 21 from being cut.

[0134] Depending on the structure of the matching portion, the cutting portion 133 can be arranged in different ways. In a specific embodiment of the present disclosure, the cutting portion 133 and the matching portion are located on both sides of the drum 21; or the matching portion is configured to have an arc-shaped groove that is adapted to at least part of the surface of the drum 21, and the cutting portion 133 is located on one side of the arc-shaped groove.

[0135] like Fig.12 As shown, when the matching part is a wheel set 135, the cutting part 133 can be arranged on the mounting bracket 131. Specifically, a protrusion 1314 is arranged in the middle position of the mounting bracket 131, and the driving wheel is mounted on the protrusion 1314. A space for accommodating the drum 21 is formed on one side of the protrusion 1314, and the drum 21 can be seated on one side of the protrusion 1314, and the protrusion 1314 plays a role in limiting the position of the drum 21. In this embodiment, the driving wheel is located on one side of the drum 21, and the cutting part 133 is located on the other side of the drum 21. In other words, one side of the drum 21 can keep matching with the driving wheel, thereby driving the self-cleaning assembly 13 to move, and the other side of the drum 21 can match with the cutting part 133, and the cutting part 133 extends into the fluff, thereby cutting off the hair entangled on the surface of the drum 21.

[0136] like Figure 4As shown, when the matching part is a driving seat 134, the cutting part 133 can be integrally formed with the driving seat 134. Specifically, the driving seat 134 has an arc groove adapted to a part of the surface of the drum 21, and the drum 21 can be seated on the arc groove, and the arc groove plays a role of limiting the drum 21. The driving member 1341 is located in the arc groove, so as to convert the torque of the rotation of the drum 21 into an axial force. The cutting part 133 is integrally formed on one side of the driving seat 134. When the drum 21 is seated in the driving seat 134, the cutting part 133 extends into the fluff, thereby cutting off the hair entangled on the surface of the drum 21.

[0137] In a specific embodiment of the present disclosure, reference Figure 4 and Fig.12 The cutting part 133 includes a knife holder 1332 located on the cleaning part. In the axial direction of the drum 21, an open slot is provided on the knife holder 1332, and a knife head 1331 is provided in the open slot. The knife holder 1332 can play the role of assisting the knife head 1331 in guiding and protecting the knife head 1331. The knife holder 1332 can be directly inserted into the fluff on the surface of the drum 21, and the knife head 1331 is also sent into the fluff, so as to achieve the effect of cutting off the hair entangled on the surface of the drum 21. The cut hair will fall from the surface of the drum 21 into the cleaning tank 121, and will be scraped by the self-cleaning component 13 to the sewage discharge area 124 for treatment.

[0138] According to the second aspect of the present disclosure, a base station 10 is also provided, which is configured to dock a cleaning device, and includes a base 12 and a self-cleaning assembly 13. A cleaning tank 121 is provided on the base 12, and the cleaning tank 121 is configured to receive the cleaning elements of the cleaning device, and the cleaning tank 121 is provided with a sewage discharge area 124. The directions of the opposite ends of the cleaning tank 121 are respectively recorded as the first direction and the second direction. The self-cleaning assembly 13 is configured to be movably connected to the base 12, and is configured to move in the first direction and the second direction under the action of an external force; in the process of moving in the first direction, the self-cleaning assembly 13 approaches the sewage discharge area 124, and scrapes the cleaning tank 121 to push the dirt to the sewage discharge area 124 for discharge; in the process of moving in the second direction, the self-cleaning assembly 13 moves away from the sewage discharge area 124 and leaves the surface to be cleaned of the cleaning tank 121.

[0139] The present disclosure realizes automatic cleaning of the cleaning tank 121 by setting a self-cleaning component 13 that is movably connected to the base 12. A sewage discharge area 124 is set in the cleaning tank 121, and the sewage discharge area 124 can be set at one end of the cleaning tank, and the self-cleaning component 13 can move to the location of the sewage discharge area. The self-cleaning component 13 can move in a first direction under the action of an external force, so as to transport the dirt in the cleaning tank 121 to the sewage discharge area 124; in the process of moving in the second direction, the self-cleaning component 13 is separated from the surface to be cleaned of the cleaning tank 121, so as to avoid scraping the dirt back from the sewage discharge area 124, and avoid pushing the dirt to both ends. In this way, only the sewage discharge area 124 needs to be set at one end, which reduces the cost. The user only needs to clean one end of the cleaning tank 121, which is convenient for maintenance and improves the sewage discharge effect. The user no longer needs to manually clean the cleaning tank 121, and can automatically maintain the cleanliness of the cleaning tank 121 by relying solely on the self-cleaning component 13, thereby improving the user experience.

[0140] Application scenario 1

[0141] In a household cleaning scenario, the cleaning system of the present disclosure includes a sweeping and mopping robot for cleaning the bottom surface and a base station 10 for docking the sweeping and mopping robot. After completing the cleaning work, the sweeping and mopping robot can dock in the base station 10 for maintenance work such as charging, dust collection, and sewage discharge. The sweeping and mopping robot is provided with a roller 21, and the surface of the roller 21 is provided with fluff, so that it can attach water and clean the ground.

[0142] The base station 10 includes: a body 11, a base 12 and a self-cleaning component 13, wherein the body 11 is provided with components such as a clean water bucket, a dirty water bucket, a dust collection chamber, and a dust collection pipe, so that the base station 10 has a complete maintenance function. The base 12 is located below the body 11 and forms a receiving chamber with the body 11. After finishing the cleaning work, the sweeping and mopping robot can automatically drive to the receiving chamber and dock on the base 12.

[0143] The base 12 is provided with a cleaning tank 121, which is configured to cooperate with the roller 21 of the cleaning device to receive and maintain the dirt of the cleaning device. When the sweeping and mopping robot is docked in the base station 10, the roller 21 is configured to be located above the cleaning tank 121. The roller 21 rotates along its axial direction during cleaning to shake off the dirt attached to its surface; in addition, the roller 21 can be flushed with clean water to flush the dirt away from the roller 21. The dirt separated from the roller 21 will fall into the cleaning tank 121 under the action of gravity, thereby avoiding polluting the environment outside the base station 10.

[0144] A sewage discharge area 124 is provided on one side of the cleaning tank 121. The self-cleaning assembly 13 is constructed to be movably connected to the base 12 and is configured to move along the extension direction of the cleaning tank 121 under the action of the rotation of the drum 21. The first direction and the second direction are defined to extend along the extension direction of the drum 21, and the first direction and the second direction are opposite in direction. In the process of moving in the first direction, the self-cleaning assembly 13 approaches the sewage discharge area 124 and scrapes the cleaning tank 121 to push the dirt to the sewage discharge area 124 for discharge. In the process of moving in the second direction, the self-cleaning assembly 13 moves away from the sewage discharge area 124 and leaves the surface to be cleaned of the cleaning tank 121. Specifically, the self-cleaning assembly 13 includes a mounting bracket 131 and a driving seat 134 provided on the mounting bracket 131. The surface of the driving seat 134 for cooperating with the drum 21 is provided with an inclined extending driving member 1341. The driving member 1341 is a protruding structure provided on the surface of the driving seat 134. The driving member 1341 is configured to convert the torque of the drum 21 during forward rotation into a first axial force moving toward the sewage discharge area 124 , and to convert the torque of the drum 21 during reverse rotation into a second axial force moving away from the sewage discharge area 124 .

[0145] That is, when the drum 21 rotates forward along the first rotation direction, under the conversion action of the drive seat 134, the self-cleaning assembly 13 moves toward the sewage discharge area 124 along the first direction as a whole, and transports the dirt to the sewage discharge area 124 for treatment, so that there is no dirt residue on the surface of the cleaning tank 121, and the user no longer needs to manually clean the cleaning tank 121. When the drum 21 rotates along the second rotation direction, under the conversion action of the drive seat 134, the self-cleaning assembly 13 moves away from the sewage discharge area 124 along the second direction as a whole, thereby achieving reset.

[0146] A plurality of toggle protrusions 211 may be provided in the axial direction of the drum 21, and the toggle protrusions 211 are configured not to exceed the fluff on the drum 21. The toggle protrusions 211 may increase the friction between the drum 21 and the drive seat 134, thereby improving the efficiency of self-cleaning. Specifically, the toggle protrusions 211 are only provided in the middle area of ​​the drum 21, thereby forming a power zone 22; the toggle protrusions 211 are not provided in the areas at the opposite ends of the power zone 22, thereby forming two non-power zones 23.

[0147] Under the action of the rotational force of the drum 21, the self-cleaning component 13 can move to the edge position at one end of the cleaning tank 121. At this time, the drum 21 will usually continue to maintain the current rotation state, but the self-cleaning component 13 can no longer move. Therefore, it is necessary to ensure that when the self-cleaning component 13 runs to the edge position, the drum 21 will not be stuck due to the action of the self-cleaning component 13. To this end, the present disclosure only sets a toggle protrusion 211 in the middle area of ​​the drum 21, forming a power zone 22 with very high transmission efficiency; and on both sides of the drum 21, no toggle protrusion 211 is set to prevent the driving member 1341 on the self-cleaning component 13 that moves to the edge from being stuck with the toggle protrusion 211.

[0148] A cleaning member 132 is provided at the bottom of the mounting bracket 131, and the cleaning member 132 may be a scraper. When the drum 21 rotates forward along the first rotation direction, the self-cleaning assembly 13 moves toward the sewage discharge area 124, and the cleaning member 132 is configured to be pre-pressed on the bottom of the cleaning tank 121 to scrape the dirt to the sewage discharge area 124. When the drum 21 rotates reversely along the second rotation direction, the self-cleaning assembly 13 moves away from the sewage discharge area 124, and the cleaning member 132 has a tendency to separate from the cleaning tank 121 under the action of the friction force of the cleaning tank 121. In this way, the cleaning member 132 can be prevented from scraping the dirt from the sewage discharge area 124 back to the cleaning tank 121, and the scraped dirt can be left in the sewage discharge area 124 for processing during the forward rotation of the drum 21, and will not be brought back by the cleaning member 132 when the drum 21 starts to reverse.

[0149] A reflow zone 127 is formed between the two opposite sides of the cleaning member 132 and the cleaning tank 121. When the cleaning member 132 moves in the second direction, the dirt in the cleaning tank 121 is configured to flow toward the direction close to the sewage discharge zone 124 through the reflow zone 127. Specifically, the reflow zone 127 is a gap provided on both sides of the cleaning member 132, and the gap width is about 3-5 mm. The dirt can flow to the other side of the cleaning member 132 through the reflow zone 127, thereby preventing the dirt from being squeezed out of the cleaning tank 121 by the cleaning member 132, and also preventing the dirt from accumulating on the side away from the sewage discharge zone 124.

[0150] A cutting portion 133 is also integrally formed on the drive seat 134. The cutting portion 133 is configured to extend into the fluff of the drum 21 to cut foreign matter, such as hair, wrapped around the surface of the drum 21 during movement. Specifically, the drive seat 134 has an arc groove adapted to a part of the surface of the drum 21, and the drum 21 can be seated on the arc groove, and the arc groove plays a role of limiting the drum 21. The driving member 1341 is located in the arc groove, thereby converting the torque of the rotation of the drum 21 into an axial force. The cutting portion 133 is integrally formed on one side of the drive seat 134. When the drum 21 is seated in the drive seat 134, the cutting portion 133 extends into the fluff, thereby cutting off the hair wrapped around the surface of the drum 21. The cut hair will fall from the surface of the drum 21 into the cleaning tank 121, and will be scraped by the self-cleaning assembly 13 to the sewage discharge area 124 for treatment.

[0151] In this way, the cleaning tank 121 can be automatically cleaned. The self-cleaning component 13 can move along the extension direction of the cleaning tank 121 under the action of the rotation of the drum 21, so as to transport the dirt in the cleaning tank 121 to the sewage discharge area 124, and at the same time, it can also cut off the hair wrapped around the surface of the drum 21. The self-cleaning component 13 is separated from the bottom of the cleaning tank 121 during the movement in the second direction, so as to avoid scraping the dirt back from the sewage discharge area 124 and avoid pushing the dirt to both ends. In this way, only the sewage discharge area 124 needs to be set at one end, which reduces the cost. The user only needs to clean one end of the cleaning tank 121, which is convenient for maintenance and improves the sewage discharge effect. The user no longer needs to manually clean the cleaning tank 121 and the drum 21. The self-cleaning component 13 can automatically maintain the cleanliness of the cleaning tank 121 and the drum 21, thereby improving the user experience.

[0152] Application scenario 2

[0153] Also in the household cleaning scenario, the present disclosure also provides a different cleaning system, which is different from the cleaning system in the first application scenario in that the structure of the self-cleaning component 13 on the base station 10 is different.

[0154] The self-cleaning assembly 13 includes a mounting bracket 131 and a wheel set 135 disposed on the mounting bracket 131, and the wheel set 135 includes a driving wheel and a running wheel 1356 connected to the driving wheel. The driving wheel is used to contact and cooperate with the drum 21, and is configured to be controlled by the rotation of the drum 21, and the running wheel 1356 is configured to be controlled by the rotation of the driving wheel to drive the self-cleaning assembly 13 as a whole to move between the first end and the second end of the cleaning tank 121. Specifically, the wheel set 135 also includes a transmission wheel 1354 meshed with the driving wheel, and the transmission wheel 1354 and the running wheel 1356 are configured to be connected together through a rotating shaft 1355, so as to achieve coaxial rotation.

[0155] The driving wheel and the transmission wheel 1354 may have different rotation directions. Specifically, the rotation axis of the driving wheel may be consistent with the drum 21, while the rotation axes of the transmission wheel 1354, the rotation shaft 1355 and the walking wheel 1356 are perpendicular to the rotation axis of the drum 21. The driving wheel may be provided with a connecting portion 1353, and the surface of the connecting portion 1353 is provided with densely arranged threads. The teeth of the transmission wheel 1354 are meshed with the above threads, so that the direction of rotation is changed.

[0156] The driving wheel includes a first driving wheel 1351 and a second driving wheel 1352 which are spaced apart on both sides of the connecting portion 1353. The drum 21 will not stop rotating or reverse rotating after the self-cleaning assembly 13 reaches the edge, but will usually continue to maintain the current rotating state. When the self-cleaning assembly 13 moves to the edge of the cleaning tank 121 under the continuous forward rotation of the drum 21, the first driving wheel 1351 is disengaged from the drum 21, and the second driving wheel 1352 keeps matching with the drum 21, so that the resistance faced by the drum 21 when it continues to rotate forward can be reduced. At this time, only the second driving wheel 1352 is in contact with the drum 21. Compared with the state where the two driving wheels are in contact together, the interaction force between the drum 21 and the self-cleaning assembly 13 is greatly reduced, thereby avoiding the situation where the drum 21 is stuck due to excessive resistance. Similarly, when the self-cleaning assembly 13 moves to the edge of the other side of the cleaning tank 121 under the continuous reverse rotation of the drum, the drum 21 can still keep reversing and will not get stuck.

[0157] The mounting bracket 131 is slidably fitted on the base 12, and a rack 129 meshing with the running wheel 1356 is provided on the base 12, and the running wheel 1356 is configured to run along the rack 129 during the rotation process. Racks 129 are respectively provided on both sides of the base 12 in the width direction, and two running wheels 1356 provided at both ends of the rotating shaft 1355 are respectively meshed on the two racks 129. When the running wheel 1356 rotates, that is, it runs along the rack 129, so that the self-cleaning assembly 13 can be driven to move relative to the base 12 as a whole.

[0158] A protrusion 1314 is provided in the middle of the mounting bracket 131, and the driving wheel is mounted on the protrusion 1314. A space for accommodating the drum 21 is formed on one side of the protrusion 1314, and the drum 21 can be seated on one side of the protrusion 1314, and the protrusion 1314 plays a role in limiting the position of the drum 21.

[0159] A cutting portion 133 is also provided on the mounting bracket 131, the driving wheel is located on one side of the drum 21, and the cutting portion 133 is located on the other side of the drum 21. In other words, one side of the drum 21 can be matched with the driving wheel to drive the self-cleaning assembly 13 to move, and the other side of the drum 21 can be matched with the cutting portion 133, and the cutting portion 133 extends into the fluff to cut off the hair entangled on the surface of the drum 21.

[0160] In this way, the cleaning tank 121 is automatically cleaned. The self-cleaning component 13 can move along the extension direction of the cleaning tank 121 under the action of the rotation of the drum 21, so as to transport the dirt in the cleaning tank 121 to the sewage discharge area 124, and at the same time cut off the hair entangled on the surface of the drum 21. The user no longer needs to manually clean the cleaning tank 121 and the drum 21, and can automatically maintain the cleanliness of the cleaning tank 121 and the drum 21 by relying on the self-cleaning component 13, thereby improving the user experience.

[0161] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the marketplace, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
