Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning equipment and a cleaning system. BACKGROUND

[0002] The scrubber is an automatic cleaning equipment integrating water spraying, brushing and sewage suction, and is usually equipped with a self-cleaning base station to complete the cleaning and drying of the scrubber brush. At present, in the process of self-cleaning of the scrubber at the base station, the dehydration of the scrubber brush mainly adopts high-speed centrifugal spin-drying technology, that is, the scrubber brush is driven to rotate at high speed, and the water is spun out by centrifugal force. The scrubber in the related technology is still in a high water content state after completing self-cleaning at the base station, which leads to a long drying time of the scrubber and affects the user experience.

[0003] In order to shorten the drying time, it is necessary to further reduce the water content of the scrubber, and the related technology usually adopts the method of increasing the rotation speed of the scrubber for rapid spin-drying.

[0004] However, the mechanical vibration and air friction generated by the high-speed rotating scrubber will cause significant noise, resulting in poor user experience. SUMMARY

[0005] The cleaning equipment and cleaning system provided by the embodiments of the present application can reduce the water content on the scrubber after self-cleaning of the scrubber, thereby solving the problem of long drying time caused by high water content of the scrubber after self-cleaning in the related technology.

[0006] In order to achieve the above-mentioned purpose, the embodiments of the present application provide the following technical solutions:

[0007] The first aspect of the embodiments of the present application provides a cleaning equipment, which comprises a brush assembly and an equipment wiper strip. The brush assembly comprises a scrubber brush, and the scrubber brush can rotate forward and reverse around its own axis. The equipment wiper strip is arranged on the brush assembly, and the equipment wiper strip comprises a wiper tongue. The wiper tongue is in interference fit with the working surface of the scrubber brush. The wiper tongue comprises a first scraping part and a second scraping part facing the scrubber brush. When the scrubber brush rotates forward, the scrubber brush first passes through the first scraping part and then passes through the second scraping part. When the scrubber brush rotates reversely, the scrubber brush first passes through the second scraping part and then passes through the first scraping part.

[0008] The cleaning equipment in the embodiments of the present application can make the wiper tongue of the equipment wiper strip extrude the working surface of the scrubber brush by arranging the equipment wiper strip in interference fit with the scrubber brush and arranging the wiper tongue of the equipment wiper strip in interference fit with the working surface of the scrubber brush. The wiper tongue can scrape the surface of the scrubber brush when the scrubber brush rotates, and then scrape off the liquid on the scrubber brush.

[0009] By the first scraping part and the second scraping part of the scraper tongue, the sewage, particles and residual cleaning liquid attached to the roller brush can be scraped by the first scraping part when the roller brush rotates forward, and the sewage, particles and residual cleaning liquid attached to the roller brush can be scraped by the second scraping part when the roller brush rotates reversely. In this way, the scraper tongue can maintain stable water scraping performance regardless of the forward rotation or the reverse rotation of the roller brush, and can be suitable for both the conventional cleaning mode of the forward rotation of the roller brush and the self-cleaning mode of the reverse rotation of the roller brush, so that the roller brush can maintain a low water content in different working modes, reduces the drying burden after self-cleaning, shortens the drying time, and even can not be dried, but can be naturally spun dry, which can solve the problems of the long drying time of the roller brush after self-cleaning or the high noise caused by the high-speed spinning of the roller brush in the related art. In addition, this can also avoid leaving obvious water stains or sewage film on the ground during the execution of the conventional cleaning operation, achieve the cleaning effect of wiping and drying at the same time, and improve the user experience.

[0010] In a possible implementation, the scraper tongue comprises: a first scraping surface facing the roller brush; a second scraping surface facing away from the roller brush, the second scraping surface being located at one end of the first scraping surface along the height direction of the cleaning device, and the second scraping surface and the first scraping surface form a first included angle, and the first included angle is located at the first scraping part; and a third scraping surface facing away from the roller brush, the third scraping surface being located at the other end of the first scraping surface along the height direction of the cleaning device, and the third scraping surface and the first scraping surface form a second included angle, and the second included angle is located at the second scraping part.

[0011] In this way, a multi-folding surface reinforcing structure can be formed on the cross-sectional profile of the scraper tongue. This geometric shape can improve the bending stiffness of the scraper tongue in the height direction, so that it is not easy to deform plastically or vibrate when bearing the pressure of the roller brush, thereby ensuring the stability of scraping.

[0012] In a possible implementation, the first scraping surface is an arc surface; the roller brush has a first contact position with the first scraping part, the tangent direction of the roller brush at the first contact position and the second scraping surface form a third included angle, and the third included angle is an acute angle; and the roller brush has a second contact position with the second scraping part, the tangent direction of the roller brush at the second contact position and the third scraping surface form a fourth included angle, and the fourth included angle is an acute angle.

[0013] By setting the third included angle and the fourth included angle as acute angles, the ability of the second scraping surface and the third scraping surface to cut into the liquid film and the dirt can be enhanced, the scraping efficiency can be improved, and the scraped liquid is more likely to separate from the surface of the roller brush under the guidance of the centrifugal force and the scraping surface, and be sucked away by the suction port of the floor brush in time, so as to avoid the liquid being brought back to the roller brush or the working area.

[0014] In a possible implementation, the device scraping strip comprises a connecting portion fixedly connected with the scraping tongue; and the connecting portion is configured to detachably connect the device scraping strip with the floor brush assembly.

[0015] The connecting portion detachably connected with the floor brush assembly makes the maintenance and replacement of the device scraping strip simple and efficient. Since the device scraping strip is worn out due to continuous interference and friction with the roller brush during long-term use, the detachable connecting structure can quickly remove the device scraping strip alone for cleaning or replacement without disassembling the entire floor brush assembly, thereby reducing the maintenance cost and time and not affecting the service life of other core structures of the floor brush assembly.

[0016] In a possible implementation, the floor brush assembly comprises a dirt suction port configured as an inlet of the cleaning device for sucking dirt; the device scraping strip is located at the top of the dirt suction port; the connecting portion is provided with a flow guide hole in communication with the dirt suction port; and the flow guide hole is configured as a passage for the liquid flow scraped off the roller brush to the dirt suction port.

[0017] In this way, the liquid scraped off the roller brush can flow from the side of the scraping tongue away from the roller brush to the flow guide hole, and then flow into the dirt suction port of the floor brush assembly through the flow guide hole, so as to suck the liquid scraped off the roller brush directly into the sewage tank of the cleaning device, preventing the liquid from flowing back to the roller brush and avoiding secondary pollution of the roller brush.

[0018] In a possible implementation, the flow guide hole is arranged close to the scraping tongue.

[0019] By arranging the flow guide hole close to the scraping tongue, the short-path liquid guiding effect can be optimized. The liquid scraped off the roller brush can be guided into the dirt suction port in time, effectively reducing the attachment and residue of the liquid on the surface of the device scraping strip and reducing the possibility of bacterial growth or odor generation caused by liquid retention.

[0020] In a possible implementation, the floor brush assembly further comprises a combing member; the device scraping strip is located at the top of the combing member; and the combing member and the scraping tongue form a flow guide gap for liquid outflow.

[0021] By arranging the combing member below the device scraping strip, the roller brush bristles can be further combed in detail by the combing member after the device scraping strip removes most of the liquid and attached dirt from the roller brush, so as to separate the entangled hair and particulate matter. By arranging the flow guide gap between the combing member and the scraping tongue, a stable transition passage can be provided for the liquid flowing down the scraping tongue, so that the liquid can flow into the dirt suction port smoothly.

[0022] In a possible implementation, the third included angle and / or the fourth included angle ranges from 30° to 60°.

[0023] In this way, the second scraping surface or the third scraping surface can be arranged to cut into the liquid film and the dirt layer on the surface of the rolling brush at a sufficiently steep angle, thereby generating effective scraping effect and efficiently stripping the liquid or contaminants. The angle avoids the problems of insufficient scraping force and poor liquid flow direction caused by a too small included angle (e.g., less than 30°), and avoids the problems of excessive resistance, increased rolling brush rotation load and accelerated scraping strip wear caused by a too large included angle (e.g., greater than 60°).

[0024] In a possible implementation, in a cross section perpendicular to the rotation axis of the rolling brush, the cross-sectional shape of the device scraping strip is wedge-shaped, and the wider side of the wedge-shaped cross section faces the rolling brush.

[0025] By designing the cross section of the device scraping strip to be wedge-shaped and gradually wider towards the rolling brush, a natural reinforcement rib effect is formed mechanically, thereby improving the overall bending stiffness of the device scraping strip. The wider side of the cross section (i.e., the scraping tongue close to the rolling brush) provides a larger material distribution, thereby enhancing the ability of the scraping tongue to resist the radial pressure and circumferential friction applied by the rotation of the rolling brush, effectively preventing the device scraping strip from being deformed or vibrated in long-term interference fit, thereby ensuring that the scraping surface maintains constant and uniform contact pressure with the surface of the rolling brush.

[0026] In a possible implementation, the second scraping surface is a flat surface or an arc-shaped surface; and / or, the third scraping surface is a flat surface or an arc-shaped surface.

[0027] In this way, the design flexibility of the second scraping surface and / or the third scraping surface can be improved. When the scraping surface is designed as a flat surface, the manufacturing process is simple and low in cost, and the contact with the rolling brush is linear or narrow-surface contact, which can generate a higher local pressure and is conducive to the strong scraping of sticky contaminants or thick liquid film. When the scraping surface is designed as an arc-shaped surface, it helps to guide the scraped liquid to flow smoothly along the curved surface to the flow guide structure, reducing splashing or residue.

[0028] The second aspect of the embodiments of the present application provides a cleaning system, which includes a cleaning base station and a cleaning device according to any one of the first aspect, and the cleaning base station is used at least for the cleaning device to complete self-cleaning.

[0029] The cleaning system in the embodiments of the present application can have all the advantages of the cleaning device described above by including the cleaning device of the first aspect. The water content of the rolling brush on the floor brush assembly of the cleaning device of the cleaning system is low, which can avoid leaving obvious water stains or sewage film on the ground during normal cleaning operation, and can also shorten the drying time during self-cleaning.

[0030] In a possible implementation, the cleaning base station comprises: a base comprising a cleaning tank for accommodating the brush assembly; a base scraping strip fixed in the cleaning tank and interfering with the working surface of the roller brush when the brush assembly is placed in the cleaning tank; the base scraping strip comprises a first acting portion and a second acting portion facing the roller brush; when the roller brush rotates forward, the roller brush first passes through the first acting portion and then passes through the second acting portion; when the roller brush rotates reversely, the roller brush first passes through the second acting portion and then passes through the first acting portion.

[0031] By arranging the base scraping strip with the same function as the device scraping strip on the base, when the brush assembly of the cleaning device is placed in the cleaning tank of the base, the roller brush also interferes with the base scraping strip, so that the scraping effect on the roller brush is further increased, the water content on the roller brush is further reduced, and the subsequent drying time is further shortened. In addition, when the device scraping strip fails, the roller brush can also be scraped by the base scraping strip to ensure that the water content on the roller brush is in a low state and the stability of the system is ensured.

[0032] The system combines daily maintenance (device self-cleaning) and deep maintenance (base scraping) organically, ensures that the roller brush can be restored to a low water content and high cleaning degree state after each use, maintains the cleaning performance of the cleaning device, reduces the drying burden after self-cleaning, shortens the drying time, and even can not be dried, but can be naturally spun dry. The problem that the water content of the roller brush is high after self-cleaning in the related art, which leads to a long subsequent roller brush drying time or a high noise caused by high-speed spinning of the roller brush can be solved.

[0033] In a possible implementation, the base scraping strip comprises: a first acting surface facing the roller brush; a second acting surface facing away from the roller brush, the second acting surface being located at one end of the first acting surface in the height direction of the base, and the second acting surface and the first acting surface forming a first corner, the first corner being the first acting portion; and a third acting surface facing away from the roller brush, the third acting surface being located at the other end of the first acting surface in the height direction of the base, and the third acting surface and the first acting surface forming a second corner, the second corner being the second acting portion.

[0034] In this way, a multi-folding surface reinforcing structure can be formed on the cross-sectional profile of the base scraping strip. This geometric shape can improve the bending stiffness of the base scraping strip in the height direction, so that plastic deformation or vibration is less likely to occur when the base scraping strip bears the pressure of the roller brush, thereby ensuring the stability of the scraping.

[0035] In a possible implementation, the first acting surface is an arc surface; the roller brush contacts the first acting portion at a first position, and the tangent direction of the roller brush at the first position forms a first acute angle with the second acting surface; and the roller brush contacts the second acting portion at a second position, and the tangent direction of the roller brush at the second position forms a second acute angle with the third acting surface.

[0036] By interfering with the roller brush surface at a specific acute angle between the second and third working surfaces of the base station scraper, the corresponding working surfaces can apply effective scraping force to the roller brush surface regardless of whether the roller brush rotates clockwise or counterclockwise during the self-cleaning process. This powerfully removes stubborn stains, tangled hair, and residual cleaning solution accumulated during outdoor cleaning operations.

[0037] In one possible implementation, there is a gap between the base station scraper and the bottom wall of the cleaning tank, the gap being configured as a channel for liquid scraped off the roller brush to enter the cleaning equipment.

[0038] By creating a gap between the base station scraper and the bottom wall of the cleaning tank, a flow channel is provided for the liquid scraped off the roller brush, allowing it to be discharged or recycled. Specifically, when the roller brush rotates and self-cleans within the cleaning tank, the mixture of wastewater, dirt, and cleaning fluid forcefully scraped off by the base station scraper drips downwards under the influence of gravity and centrifugal force. This gap acts as a directional channel, allowing the liquid to quickly flow away from the scraping area and be guided to the drain outlet at the bottom of the cleaning tank or the suction port of the cleaning equipment itself, thus enabling effective recycling by the cleaning equipment or the base station's wastewater discharge system. This prevents dirt scraped off the roller brush from accumulating at the bottom of the scraper and forming a secondary source of pollution, and also prevents liquid from splashing out of the cleaning tank, ensuring the cleanliness and efficiency of the self-cleaning process, while facilitating subsequent cleaning and maintenance of the cleaning tank.

[0039] In one possible implementation, when the brush rotates forward, the first actuating part can apply a first scraping force opposite to the direction of forward rotation to the working surface of the brush; when the brush rotates in reverse, the second actuating part is used to apply a second scraping force opposite to the direction of reverse rotation to the working surface of the brush.

[0040] By setting the direction of the scraping force applied by the first and second working parts to always be opposite to the direction of the roller brush's rotation, a positive shearing action can be generated on the roller brush in both forward and reverse rotation, thereby efficiently stripping liquid and dirt from the roller brush surface. This allows the roller brush's self-cleaning process to operate without relying on a single direction of rotation, enabling more thorough cleaning of different areas of the roller brush through alternating forward and reverse rotation, making it particularly suitable for removing particles embedded in the roots of the bristles.

[0041] In one possible implementation, the range of the first acute angle and / or the second acute angle is 30°-60°.

[0042] In this way, the second and third action surfaces can cut into the liquid film and dirt layer on the surface of the rolling brush at a sufficiently steep angle, generating effective scraping action, thereby efficiently stripping the liquid or contaminants. This angle avoids the problems of insufficient scraping force and poor liquid flow direction caused by a too small included angle (e.g. less than 30°), and avoids the problems of excessive resistance, increased rolling brush rotation load and accelerated scraping strip wear caused by a too large included angle (e.g. greater than 60°).

[0043] In one possible implementation, the first action surface is an arc surface, the center of the arc surface is located at the axis of the rolling brush, and the curvature of the arc surface is the same as the curvature of the rolling brush.

[0044] By designing the first action surface near the rolling brush as an arc surface concentric with the rolling brush, the spatial layout and interference fit between the base station scraping strip and the rolling brush can be optimized. The arc surface can ensure that the base station scraping strip and the surface of the rolling brush maintain a uniform interference amount, avoiding problems such as excessive local pressure or missed scraping caused by the non-flatness of the base station scraping strip. The arc-shaped connecting surface is more consistent with the rotation trajectory of the rolling brush in structure, which helps to guide the liquid scraped to flow along the curved surface to the predetermined collection area, reducing splashing.

[0045] In one possible implementation, in a cross section perpendicular to the rotation axis of the rolling brush, the cross-sectional shape of the base station scraping strip is wedge-shaped, with the wider side of the wedge facing the rolling brush.

[0046] By designing the cross section of the base station scraping strip as a wedge-shaped cross section that widens towards the rolling brush, a natural rib effect is formed mechanically, improving the overall bending stiffness of the base station scraping strip. The wider side of the cross section provides greater material distribution, enhancing the ability of the base station scraping strip to resist the radial pressure and circumferential friction exerted by the rolling brush rotation, effectively preventing the base station scraping strip from bending or vibrating under long-term interference fit, thereby ensuring that the device scraping strip and the surface of the rolling brush maintain constant and uniform contact pressure.

[0047] In one possible implementation, the second action surface is a flat surface or an arc surface; and / or, the third action surface is a flat surface or an arc surface.

[0048] In this way, the design flexibility of the second and / or third action surfaces can be improved, and when the action surface is designed as a flat surface, the manufacturing process is simple and low in cost, and the contact with the rolling brush is line contact or narrow surface contact, which can generate a higher local pressure, which is beneficial for strongly scraping adherent dirt or thick liquid film. When the action surface is designed as an arc surface, it helps to guide the scraped liquid to flow smoothly along the curved surface to the flow guide structure, reducing splashing or residue.

[0049] In one possible implementation, the base station scraping strip is provided with a mounting portion at both ends, and the cleaning tank is provided with a fitting portion matched with the mounting portion; the mounting portion and the fitting portion are fixedly connected.

[0050] By setting the mounting portion and the assembly portion, the precise and stable installation of the base station wiper in the cleaning tank can be realized. By setting the mounting points at both ends of the wiper, the freedom of the wiper in the axial and circumferential directions can be effectively constrained, the displacement or vibration of the base station wiper under the friction generated by the rotation of the roller brush can be prevented, and the wiping geometric relationship (such as the acute angle) can be ensured to remain at the design value for a long time. The fixed connection (such as screw locking, buckle locking, welding, etc.) provides high connection stiffness, so that the base station wiper becomes a reliable component of the cleaning tank structure, can withstand the high-intensity mechanical impact that may occur during the self-cleaning process, and ensures the reliability of the cleaning base station for a long time.

[0051] In a possible implementation, the mounting portion and the assembly portion are detachably connected.

[0052] Through the detachable connection (such as screw connection, elastic buckle, plug-in locking, etc.), the user can disassemble, clean or replace the base station wiper without professional tools or complex operations when the base station wiper is worn, aged or clogged due to long-term use. In turn, the maintenance difficulty of the cleaning base station can be reduced, and the service life of the cleaning base station can be prolonged.

[0053] In a possible implementation, the mounting portion is a flat hole structure, and the assembly portion is a flat column structure.

[0054] By setting the mounting portion as a flat hole structure (such as an oblong hole, a square hole), and setting the assembly portion as a flat column structure (such as a rectangular column, an elliptical column), the twisting tendency of the base station wiper around the rotation axis of the roller brush when subjected to force can be effectively resisted while achieving plug-in positioning. The flat mating surface can provide a larger contact area, thereby enhancing the stability of the connection. In addition, this structure is simple to process and easy to assemble, which can reduce the cost. BRIEF DESCRIPTION OF DRAWINGS

[0080] To make the objects, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0081] At present, in the self-cleaning link of the scrubber, there are problems of long self-cleaning time and large self-cleaning noise. The root cause is that the water content of the roller brush is too high after self-cleaning of the scrubber, which leads to too long drying time of the roller brush, affecting the user experience, and in order to achieve fast drying, the industry generally uses increasing the roller brush speed to perform fast spin-drying, which will cause the noise of the whole process to be abnormally large, resulting in poor user experience.

[0082] In order to solve the above problems, the embodiments of the present application provide a cleaning device and a cleaning system, by setting a device scraping strip with a specific structure on the cleaning device, the water in the roller brush is scraped away during self-cleaning, so that the roller brush is in a low water content state after self-cleaning, and only low-speed drying is left to achieve the effect of fast and silent drying.

[0083] The cleaning device and the cleaning system provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings.

[0084] Figure 1 A structure schematic diagram of a cleaning system provided by the embodiments of the present application.

[0085] It should be noted that, in order to facilitate description, in the embodiments of the present application, the height direction of the cleaning base station is taken as the z direction, the axial direction of the roller brush is taken as the y direction, and the advancing direction of the cleaning device is taken as the x direction.

[0086] The application provides a cleaning system 1000, as shown in the drawings. Figure 1 The cleaning system 1000 can include a cleaning device 100 and a cleaning base station 200, wherein the cleaning device 100 can be a mobile device for performing cleaning work on the ground, such as a scrubber, a sweeping robot or a vacuum cleaner, etc., the bottom of the cleaning device 100 is provided with a floor brush assembly 110, the floor brush assembly 110 includes a rotatable roller brush 112, and the cleaning base station 200 is used at least for the cleaning device 100 to complete self-cleaning.

[0087] The cleaning base station 200 can be a fixedly arranged matching device, which is usually placed in a corner of a room or a special area, and can include a base 210, wherein the base 210 can be provided with a cleaning tank 211, a drainage system and a control module, etc. When the cleaning device 100 completes the ground cleaning task or needs to be maintained, the user can place or dock the cleaning device 100 to the cleaning base station 200, and the cleaning base station 200 can automatically or according to the instruction start the self-cleaning program.

[0088] In the self-cleaning program, the roller brush 112 of the cleaning device 100 rotates in the cleaning tank 211 of the cleaning base station 200, while the cleaning base station 200 or the cleaning device 100 can spray clean water or cleaning liquid to the roller brush 112, and the surface of the roller brush 112 is deeply scraped and cleaned by the scraping structure on the cleaning device 100 or the cleaning base station 200, and the sewage after scraping the dirt is recycled by the cleaning device 100 and / or recycled or discharged by the drainage system of the cleaning base station 200. The cleaning system 1000 can realize the cleaning and maintenance of the roller brush 112 through the cooperation of the cleaning device 100 and the cleaning base station 200, and significantly improve the long-term working efficiency and hygiene level of the cleaning device 100.

[0089] The cleaning device 100 and the cleaning base station 200 in the application will be described in detail below with reference to the drawings.

[0090] The application provides a cleaning device 100, as shown in the drawings. Figure 2 The cleaning device 100 can include a machine body 120, a floor brush assembly 110 and a device scraping strip 130, the floor brush assembly 110 is arranged at the bottom of the machine body 120, and the device scraping strip 130 is arranged on the floor brush assembly 110. The machine body 120 can be provided with a clean water tank, a sewage tank, a power supply unit and a control module, etc.

[0091] It should be noted that the clean water tank is used to store clean water or cleaning liquid required for cleaning operation, and is connected to the water spraying port near the front of the brush assembly 110 or the rolling brush 112 through the pumping pipeline, and sprays water to wet the ground or the rolling brush 112 as needed during the cleaning process. The sewage tank is used to collect the mixture of sewage, particles and scraped dirt sucked by the brush assembly 110 during the cleaning process, which is communicated with the suction port 114 in the brush assembly 110 through the negative pressure sewage suction pipeline. The power supply unit (such as a rechargeable battery pack) provides power for the driving motor, water pump, fan and control system of the device. The control module is integrated inside the body 120, which can coordinate the functions of rolling brush 112 rotation, water spraying control, suction adjustment and travel driving, and support communication with the cleaning base station 200 to trigger or respond to the self-cleaning program.

[0092] In the embodiments of the present application, the structure of the body 120 of the cleaning device 100 can refer to the structure of the body 120 in the related art. In the embodiments of the present application, the structure of the body 120 is not further limited.

[0093] In the embodiments of the present application, the brush assembly 110 is a functional module that directly performs cleaning operation, and is internally provided with a rolling brush 112, a driving mechanism, a sewage suction port 114 and a device scraping strip 130, which together realize the cooperative operation of wiping, scraping and sucking.

[0094] As shown in Figure 2 The brush assembly 110 can include a housing 111 and a rolling brush 112, the rolling brush 112 is rotationally arranged at the front end of the housing 111, and the rolling brush 112 can be positively and reversely rotated around its own axis. The device scraping strip 130 is arranged on the brush assembly 110, and the device scraping strip 130 can include a scraping tongue 131 and a connecting portion 132 connected with each other, wherein the scraping tongue 131 is in interference fit with the working surface of the rolling brush 112, and the connecting portion 132 is used to connect the device scraping strip 130 and the housing 111 of the brush assembly 110.

[0095] It should be noted that, since the surface of the roller brush 112 is typically covered with elastic fibers or fibrous material, the "interference fit" in this embodiment refers to a partial structure of the scraper tongue 131 compressing the working surface of the roller brush 112 (e.g., the fiber layer 1121) inward, allowing the scraper tongue 131 to scrape the working surface of the roller brush 112. This interference fit is not rigid compression, but rather utilizes the elastic deformation characteristics of the fiber layer 1121 to ensure that the scraper tongue 131 continuously adheres to the surface of the roller brush 112 and exerts a uniform compression effect on the fiber layer 1121 when the roller brush 112 rotates. The rebound force generated by the compressed fiber layer 1121 reacts to the scraper tongue 131, forming a dynamic contact pressure, thereby ensuring that the scraper tongue 131 can effectively cut into the gaps between the fibers and squeeze out the liquid and dirt trapped therein. This interference fit based on elastic contact can avoid the damage to the fibers that may be caused by rigid scraping, and can also maintain a stable scraping effect through continuous pressure, so as to achieve efficient cleaning and dehydration of the working surface of the roller brush 112.

[0096] For example, the scraper blade 130 is parallel to the rotation axis of the roller brush 112. This allows the scraper tongue 131 to simultaneously contact the surface of the roller brush 112 along its entire axial length, ensuring that liquids and dirt on the working surface of the roller brush 112 are continuously and completely scraped away when it rotates, avoiding blind spots in cleaning caused by the scraper blade being tilted or insufficient in length. In the parallel state, the scraping force is evenly distributed along the axial direction of the roller brush 112, which can prevent local wear or deformation of the roller brush 112 due to uneven force, while reducing the risk of premature failure of the scraper blade due to excessive force on one side, and improving the service life of both components.

[0097] For example, the length of the scraper 130 in the y-direction can be the same as the length of the roller brush 112 in the y-direction. This allows the entire roller brush 112 to be effectively scraped, resulting in a lower moisture content across the entire roller brush 112, thereby shortening the subsequent drying time of the roller brush 112.

[0098] like Figure 3 and Figure 3A As shown, the scraper tongue 131 may include a first scraping portion 131a and a second scraping portion 131b facing the roller brush 112. When the roller brush 112 rotates clockwise, it passes the first scraping portion 131a and then the second scraping portion 131b. When the roller brush 112 rotates counterclockwise, it passes the second scraping portion 131b and then the first scraping portion 131a. The first scraping portion 131a and the second scraping portion 131b are spaced apart along the z-direction.

[0099] The cleaning device 100 in the embodiments of the present application can make the scraping tongue 131 of the device scraping strip 130 extrude the working surface of the roller brush 112, and then scrape the surface of the roller brush 112 when the roller brush 112 rotates, and then scrape the liquid on the roller brush 112, by setting the device scraping strip 130 in interference fit with the roller brush 112, and forming interference fit between the scraping tongue 131 of the device scraping strip 130 and the working surface of the roller brush 112.

[0100] By the first scraping part 131a and the second scraping part 131b of the scraping tongue 131, the sewage, particulate matter and residual cleaning liquid attached to the roller brush 112 can be scraped by the first scraping part 131a when the roller brush 112 rotates forward, and the sewage, particulate matter and residual cleaning liquid attached to the roller brush 112 can be scraped by the second scraping part 131b when the roller brush 112 rotates reversely.

[0101] In this way, whether the roller brush 112 rotates forward or reversely, the device scraping strip 130 can maintain stable water scraping performance, and can be applicable to both the conventional cleaning mode of the forward rotation of the roller brush 112 and the self-cleaning mode of the reverse rotation of the roller brush 112, so that the roller brush 112 can maintain a low water content in different working modes, reduce the drying burden after completing self-cleaning, shorten the drying time, and even can not be dried, but can be naturally spun dry, so that the problem of long drying time of the roller brush 112 or high noise of the high-speed spinning of the roller brush 112 due to high water content of the roller brush 112 after self-cleaning in the related art can be solved.

[0102] In addition, in this way, when the conventional cleaning operation is performed, the obvious water stains or sewage film left on the ground can be avoided, the cleaning effect of wiping and drying at the same time can be achieved, and the user experience can be improved.

[0103] In a possible implementation manner, as shown in Figure 3A The scraping tongue 131 can include a first scraping surface 1313, a second scraping surface 1311 and a third scraping surface 1312. The first scraping surface 1313 faces the roller brush 112. In use, the first scraping surface 1313 can extrude the working surface of the roller brush 112.

[0104] The second scraping surface 1311 is away from the roller brush 112. The second scraping surface 1311 is located at one end of the first scraping surface 1313 along the height direction (z direction) of the cleaning device 100, and the second scraping surface 1311 forms a first included angle a1 with the first scraping surface 1313. The first included angle a1 is located at the first scraping part 131a.

[0105] The third scraping surface 1312 is located at the other end of the first scraping surface 1313 in the height direction (z direction) of the cleaning device 100 and faces away from the roller brush 112. The third scraping surface 1312 forms a second included angle a2 with the first scraping surface 1313, and the second included angle a2 is located at the second scraping portion 131b.

[0106] As shown in the examples, the first included angle a1 and the second included angle a2 are both acute angles. In this way, the second scraping surface 1311 and the third scraping surface 1312 are respectively folded from the two ends of the first scraping surface 1313 in the z direction to the direction away from the roller brush, and then are inclined to each other.

[0107] It should be noted that in the embodiments of the present application, “towards” refers to a general direction, and is not limited to a front-to-front arrangement. “Away from” refers to a general direction, and is not limited to a back-to-back arrangement.

[0108] In this way, a multi-folding surface reinforcing structure can be formed on the cross-sectional profile of the scraping tongue 131. This geometric shape can improve the bending stiffness of the scraping tongue 131 in the height direction, so that it is not easy to deform plastically or vibrate when bearing the pressure of the roller brush 112, thereby ensuring the stability of scraping.

[0109] Continuing to refer to Figure 3A As shown in the examples, in the cross section perpendicular to the axial direction (y direction) of the roller brush 112, the cross-sectional shape of the device scraping strip 130 is wedge-shaped, and the wider side of the wedge-shaped is towards the roller brush 112.

[0110] By designing the cross section of the device scraping strip 130 to be wedge-shaped and gradually wider towards the roller brush 112, a natural reinforcing rib effect is formed mechanically, and the bending stiffness of the device scraping strip 130 as a whole is improved. Among them, the wider side of the cross section (i.e. the scraping tongue 131 close to the roller brush 112) provides a larger material distribution, enhances the ability of the scraping tongue 131 to resist the radial pressure and circumferential friction force applied by the rotation of the roller brush 112, effectively prevents the bending deformation or vibration of the device scraping strip 130 under long-term interference fit, and thus ensures that the scraping surface maintains a constant and uniform contact pressure with the surface of the roller brush 112.

[0111] As shown in the examples, Figure 3 and Figure 3A The first scraping surface 1313 can be an arc surface. As an example, the center of the arc surface is located at the axis of the roller brush 112, and the curvature of the arc surface is the same as the curvature of the roller brush 112.

[0112] By designing the first scraping surface 1313 near the roller brush 112 as an arc-shaped surface concentric with the roller brush 112, the spatial layout and interference fit between the equipment scraper 130 and the roller brush 112 can be optimized. The arc-shaped surface ensures that the surfaces of the equipment scraper 130 and the roller brush 112 maintain a uniform amount of interference, avoiding problems such as excessive local pressure or missed scraping caused by the unevenness of the equipment scraper 130. The arc-shaped first scraping surface 1313 is structurally more in line with the rotation trajectory of the roller brush 112, which helps guide the scraped liquid along the curved surface to the predetermined collection area and reduces splashing.

[0113] For example, the roller brush 112 has a first contact position with the first scraping part 131a, and the tangent direction of the roller brush 112 at the first contact position forms a third angle α3 with the second scraping surface 1311, where the third angle α3 is an acute angle. The roller brush 112 has a second contact position with the second scraping part 131b, and the tangent direction of the roller brush 112 at the second contact position forms a fourth angle α4 with the third scraping surface 1312, where the fourth angle α4 is an acute angle, so that when the roller brush 112 rotates, the second scraping surface 1311 and the third scraping surface 1312 can apply a scraping force to the outer peripheral surface of the roller brush 112 to remove liquid from the roller brush 112.

[0114] It should be noted that, Figure 3 and Figure 3A The structure is viewed from the side of the floor brush assembly 110.

[0115] By setting both the third included angle α3 and the fourth included angle α4 to acute angles, the ability of the second scraping surface 1311 and the third scraping surface 1312 to cut into the liquid film and dirt can be enhanced, improving the scraping efficiency. It also makes it easier for the scraped liquid to detach from the surface of the roller brush 112 under the guidance of centrifugal force and the scraping surface, and be sucked away in time by the suction port 114 on the ground brush, preventing the liquid from being carried back to the roller brush 112 or the working area.

[0116] For example, the connecting part 132 can be used to detachably connect the device scraper 130 to the floor brush assembly 110. The detachable connection method includes, but is not limited to, snap-fit ​​connection, screw connection, plug connection, etc. In this embodiment, the specific method of detachable connection is not further limited.

[0117] By providing a detachable connection part 132 to the floor brush assembly 110, the maintenance and replacement of the scraper blade 130 becomes simple and efficient. Since the scraper blade 130 will wear down due to continuous interference and friction with the roller brush 112 during long-term use, the detachable connection structure allows for quick removal of the scraper blade 130 for cleaning or replacement without disassembling the entire floor brush assembly 110. This reduces maintenance costs and time without affecting the service life of other core structures of the floor brush assembly 110.

[0118] In this embodiment, the scraper tongue 131 and the connecting portion 132 of the equipment scraper 130 can be integrally formed and fixedly connected, which can improve the structural strength of the equipment scraper 130 and extend its service life. Of course, in other embodiments, the scraper tongue 131 and the connecting portion 132 can also be detachably connected by means of plug-in fitting or other methods. In this way, when the scraper tongue 131 becomes unusable due to wear, only the scraper tongue 131 can be replaced instead of replacing the entire equipment scraper 130, thereby saving maintenance costs.

[0119] In one possible implementation, the range of the third and / or fourth included angles is 30°-60°. For example, the third and fourth included angles can be any value among 30°, 35°, 40°, 45°, 50°, 55°, or 60°. Furthermore, while the range of values ​​for the third and fourth included angles is the same, the specific values ​​can be the same or different. In this embodiment, the specific values ​​of the third and fourth included angles are not further limited.

[0120] This design allows the second scraping surface 1311 or the third scraping surface 1312 to cut into the liquid film and dirt layer on the surface of the roller brush 112 at a sufficiently steep angle, generating an effective scraping action and thus efficiently removing liquid or contaminants. This angle avoids the problems of insufficient scraping force and poor liquid flow direction that may be caused by too small an angle (such as less than 30°), and also avoids the drawbacks of excessive resistance, increased rotational load on the roller brush 112, and accelerated wear of the scraper strip caused by too large an angle (such as greater than 60°).

[0121] For example, the second scraping surface 1311 is a planar or curved surface. And / or, the third scraping surface 1312 is a planar or curved surface. The shapes of the second scraping surface 1311 and the third scraping surface 1312 may be the same or different. In this embodiment, the specific shapes of the second scraping surface 1311 and the third scraping surface 1312 are not further limited.

[0122] This design enhances the flexibility of the second scraping surface 1311 and / or the third scraping surface 1312. When the scraping surface is planar, its manufacturing process is simple and low-cost, and the contact with the roller brush 112 is line contact or narrow surface contact, generating higher local pressure, which is beneficial for powerfully scraping away adhesive dirt or thick liquid films. When the scraping surface is curved, it helps guide the scraped liquid smoothly along the curved surface to the guide structure, reducing splashing or residue.

[0123] like Figure 4 As shown, a guide hole 133 can be provided on the connecting part 132, wherein the guide hole 133 penetrates the connecting part 132, so that the upper and lower parts of the equipment scraper 130 can be connected.

[0124] Continuing to refer to Figure 2 As shown, the floor brush assembly 110 can include a suction port 114 configured as an inlet for the cleaning device 100 to suck up dirt. The device wiper 130 is located on top of the suction port 114, and the flow guide holes 133 on the connecting portion 132 are in communication with the suction port 114. The flow guide holes 133 are configured to guide the liquid flow scraped off the roller brush 112 to the suction port 114.

[0125] By providing the flow guide holes 133 on the connecting portion 132, the liquid scraped off the roller brush 112 can flow directly from the side of the wiper tongue 131 away from the roller brush 112 to the flow guide holes 133, and then flow into the suction port 114 of the floor brush assembly 110 through the flow guide holes 133, thereby directly sucking the liquid scraped off the roller brush 112 into the sewage tank of the cleaning device 100, preventing the liquid from flowing back to the roller brush 112 and avoiding secondary pollution of the roller brush 112.

[0126] For example, the number of flow guide holes 133 can be multiple, and the multiple flow guide holes 133 can be arranged at intervals along the axial direction (y direction) of the roller brush 112. In the embodiments of the present application, the shape and number of the flow guide holes 133 are not further limited.

[0127] In a possible implementation, the flow guide holes 133 are arranged close to the wiper tongue 131. By arranging the flow guide holes 133 close to the wiper tongue 131, the short-path drainage effect of the liquid can be optimized. The liquid scraped off the roller brush 112 can be promptly guided into the suction port 114, effectively reducing the attachment and residue of the liquid on the surface of the device wiper 130, and reducing the possibility of bacterial growth or odor generation caused by liquid retention.

[0128] As Figure 5 shown, the floor brush assembly 110 can be provided with a water spraying assembly 113 arranged on top of the suction port 114. The device wiper 130 can be integrated on the water spraying assembly 113, and the connecting portion 132 of the device wiper 130 is detachably connected with the water spraying assembly 113. The water spraying assembly 113 can include a water spraying port, which can be located on top of the connecting portion 132 of the device wiper 130, and the water spraying port is used to spray water or cleaning liquid towards the surface of the roller brush 112.

[0129] It should be noted that the water spraying assembly 113 is used to soften stains during the cleaning process, keep the roller brush 112 moderately wet, and cooperate with the device scraping strip 130 to flush the dirt to the dirt suction port 114 by spraying clean water or cleaning liquid on the roller brush 112 or the ground. The device scraping strip 130 is integrated on the water spraying assembly 113, so that the water spraying assembly 113 can scrape off the stains loosened by the water flow on the roller brush 112 and the excess liquid at the same time, and the functions of flushing and scraping can be coordinated to improve the cleaning efficiency and simplify the internal structure of the floor brush assembly 110, which is convenient for user maintenance.

[0130] In a possible implementation, the floor brush assembly 110 can further include a combing member 1131, for example, a comb tooth. The device scraping strip 130 is located on the top of the combing member 1131, and the combing member 1131 and the scraping tongue 131 form a flow guide gap 134 for liquid outflow.

[0131] For example, the combing member 1131 is integrated on the water spraying assembly 113, and the combing member 1131 is located at the bottom of the device scraping strip 130.

[0132] By arranging the combing member 1131 below the device scraping strip 130, the combing member 1131 can further comb the bristles of the roller brush 112 after the device scraping strip 130 removes most of the liquid and attached dirt from the roller brush 112, and separate the entangled hair and particles. By arranging the flow guide gap 134 between the combing member 1131 and the scraping tongue 131, a stable transition channel can be provided for the liquid flowing down the scraping tongue 131, so that the liquid can flow smoothly into the dirt suction port 114.

[0133] The cleaning base station 200 in the embodiment of the present application will be described below in conjunction with the accompanying drawings.

[0134] As shown in Figure 6 The cleaning base station 200 in the cleaning system 1000 in the embodiment of the present application can include a base 210 and a base scraping strip 220. The base 210 can include a cleaning tank 211 for accommodating the floor brush assembly 110 of the cleaning device 100. The base scraping strip 220 is fixed in the cleaning tank 211.

[0135] As shown in Figure 7 When the floor brush assembly 110 is placed in the cleaning tank 211, the base scraping strip 220 interferes with the working surface of the roller brush 112. The interference fit here is the same as the interference fit between the device scraping strip 130 and the roller brush 112, and specific reference can be made to the explanation of the interference fit between the device scraping strip 130 and the roller brush 112, which will not be repeated here.

[0136] Exemplarily, in the x direction, the base station scraping strip 220 and the device scraping strip 130 are respectively located on both sides of the rolling brush 112, so that the liquid on the rolling brush 112 can be scraped by the two special scraping strip structures during the self-cleaning process of the cleaning device 100, the liquid content on the rolling brush 112 is reduced, and the subsequent drying time is shortened.

[0137] As shown in Figure 8 The base station scraping strip 220 includes a first acting part 220a and a second acting part 220b towards the rolling brush 112. When the rolling brush 112 rotates forward, the rolling brush 112 passes through the first acting part 220a first and then passes through the second acting part 220b. When the rolling brush 112 reverses, the rolling brush 112 passes through the second acting part 220b first and then passes through the first acting part 220a.

[0138] By setting the base station scraping strip 220 with the same function as the device scraping strip 130 on the base station, when the floor brush assembly 110 of the cleaning device 100 is placed in the cleaning tank 211 of the base station, the rolling brush 112 also interferes with the base station scraping strip 220. This can further increase the scraping effect on the rolling brush 112, thereby further reducing the water content on the rolling brush 112, and further shortening the subsequent drying time. In addition, when the device scraping strip 130 fails, the rolling brush 112 can also be scraped by the base station scraping strip 220 to ensure that the water content on the rolling brush 112 is in a low state, and to ensure the stability of the system.

[0139] The system combines routine maintenance (device self-cleaning) and deep maintenance (base station scraping) organically, ensures that the rolling brush 112 can be restored to a low water content and high cleaning degree state after each use, maintains the cleaning performance of the cleaning device 100, reduces the drying burden after self-cleaning, shortens the drying time, and even can not be dried, but can be naturally spun dry. It can solve the problem that the rolling brush 112 has a high water content after self-cleaning in the related art, which leads to a long drying time of the rolling brush 112 or a large noise caused by high-speed spinning of the rolling brush 112.

[0140] In a possible implementation, the base station scraping strip 220 can include a first acting surface 223, a second acting surface 221, and a third acting surface 222. The first acting surface 223 faces the rolling brush 112, and in use, the first acting surface 223 can extrude the working surface of the rolling brush 112.

[0141] The second action surface 221 is away from the roller brush 112, and is located at one end of the first action surface 223 in the height direction of the base 210. The second action surface 221 and the first action surface 223 form a first corner m, and the first corner m is located at the first action part 220a. The third action surface 222 is away from the roller brush 112, and is located at the other end of the first action surface 223 in the height direction of the base 210. The third action surface 222 and the first action surface 223 form a second corner n, and the second corner n is located at the second action part 220b.

[0142] For example, the first corner m and the second corner n are both acute angles. In this way, the second action surface 221 and the third action surface 222 are respectively folded away from the roller brush in the z direction from both ends of the first action surface 223, and then inclined towards each other.

[0143] In this way, a multi-folding surface reinforcing structure can be formed on the cross-sectional profile of the base scraping strip 220. This geometric shape can improve the bending stiffness of the base scraping strip 220 in the height direction, so that it is not easy to deform plastically or vibrate when bearing the pressure of the roller brush 112, thereby ensuring the stability of the scraping.

[0144] In a possible implementation, the first action surface 223 is an arc surface. The roller brush 112 contacts the first action part 220a at a first position, and the tangent direction of the roller brush 112 at the first position forms a first acute angle θ1 with the second action surface 221. The roller brush 112 contacts the second action part 220b at a second position, and the tangent direction of the roller brush 112 at the second position forms a second acute angle θ2 with the third action surface 222. The first acute angle θ1 and the second acute angle θ2 are configured to respectively apply a scraping force to the outer peripheral surface of the roller brush 112 through the first action part 220a and the second action part 220b to remove liquid on the roller brush 112 when the roller brush 112 rotates.

[0145] In a possible implementation, when the roller brush 112 rotates in the forward direction, the first action part 220a can apply a first scraping force to the working surface of the roller brush 112 in the opposite direction of the forward rotation. When the roller brush 112 reverses, the second action part 220b is used to apply a second scraping force to the working surface of the roller brush 112 in the opposite direction of the reverse rotation.

[0146] The direction of the scraping force applied by the first acting part 220a and the second acting part 220b is always opposite to the rotation direction of the rolling brush 112. When the rolling brush 112 rotates forward and reverses, the rolling brush 112 can be subjected to positive shear effect, thereby efficiently stripping the liquid and dirt on the surface of the rolling brush 112. In this way, the self-cleaning program of the rolling brush 112 does not need to rely on a single rotation direction, and different areas of the rolling brush 112 can be cleaned more thoroughly by forward and reverse rotation, which is especially suitable for removing particulate matter embedded in the roots of the bristles.

[0147] In a possible implementation, the first acute angle and / or the second acute angle ranges from 30° to 60°. For example, the first acute angle and the second acute angle can be any value of 30°, 35°, 40°, 45°, 50°, 55°, or 60°. In addition, the first acute angle and the second acute angle have the same range of values, but the specific values can be the same or different. In the embodiments of the present application, the specific values of the first acute angle and the second acute angle are not limited further.

[0148] In this way, the second acting surface 221 and the third acting surface 222 can cut into the liquid film and the dirt layer on the surface of the rolling brush 112 at a steep enough angle to produce effective scraping effect, thereby efficiently stripping the liquid or contaminants. This angle avoids the problems of insufficient scraping force and poor liquid flow direction caused by a too small included angle (e.g., less than 30°), and avoids the disadvantages of excessive resistance, increased rotation load of the rolling brush 112, and accelerated wear of the scraping strip caused by a too large included angle (e.g., greater than 60°).

[0149] For example, the base station scraping strip 220 is parallel to the rotation axis of the rolling brush 112, so that the base station scraping strip 220 can simultaneously contact the surface of the rolling brush 112 along the entire axial length of the rolling brush 112, ensuring that the liquid and dirt on the working surface of the rolling brush 112 can be continuously and completely scraped off when the rolling brush 112 rotates, avoiding local cleaning blind spots caused by the inclination or insufficient length of the scraping strip. In the parallel state, the scraping force is uniformly distributed along the axial direction of the rolling brush 112, which can prevent local wear or deformation of the rolling brush 112 caused by uneven force, reduce the risk of premature failure of the scraping strip caused by excessive unilateral force, and improve the service life of the components.

[0150] For example, the length of the base station scraping strip 220 in the y direction can be the same as the length of the rolling brush 112 in the y direction. In this way, the entire rolling brush 112 can be effectively scraped, so that the water content on the entire rolling brush 112 is relatively low, thereby shortening the subsequent drying time of the rolling brush 112.

[0151] In a possible implementation, the base station wiper strip 220 comprises a connecting surface 224, which is arranged opposite to the first action surface 223 along the radial direction of the roller brush 112, and the first action surface 223 is arranged close to the center of the roller brush 112. The size of the first action surface 223 in the circumferential direction of the roller brush 112 is greater than the size of the connecting surface 224 in the circumferential direction of the roller brush 112.

[0152] That is, in the cross section perpendicular to the rotation axis of the roller brush 112, the cross-sectional shape of the base station wiper strip 220 is wedge-shaped, and the wider side of the wedge-shaped surface faces the roller brush 112.

[0153] By designing the cross section of the base station wiper strip 220 as a wedge-shaped surface that gradually widens towards the roller brush 112, a natural stiffener effect is formed mechanically, and the overall bending stiffness of the base station wiper strip 220 is improved. The wider side of the cross section provides greater material distribution, enhances the ability of the base station wiper strip 220 to resist the radial pressure and circumferential friction applied by the rotation of the roller brush 112, and effectively prevents the base station wiper strip 220 from being bent or deformed or vibrating under long-term interference fit, thereby ensuring that the device wiper strip 130 maintains constant and uniform contact pressure with the surface of the roller brush 112.

[0154] For example, the first action surface 223 is an arc-shaped surface, the center of the arc-shaped surface is located at the axis of the roller brush 112, and the curvature of the arc-shaped surface is the same as the curvature of the roller brush 112.

[0155] By designing the first action surface 223 close to the roller brush 112 as an arc-shaped surface concentric with the roller brush 112, the spatial layout and interference fit between the base station wiper strip 220 and the roller brush 112 can be optimized. The arc-shaped surface can ensure that the base station wiper strip 220 and the surface of the roller brush 112 maintain uniform interference, and avoid the problems of excessive local pressure or missed scraping caused by the unevenness of the base station wiper strip 220. The arc-shaped first action surface 223 is more consistent with the rotation trajectory of the roller brush 112 in structure, which helps to guide the liquid scraped to flow along the curved surface to the predetermined collection area, and reduces splashing.

[0156] For example, the second action surface 221 is a flat surface or an arc-shaped surface, and / or the third action surface 222 is a flat surface or an arc-shaped surface. The shapes of the second action surface 221 and the third action surface 222 can be the same or different, and in the embodiments of the present application, the specific shapes of the second action surface 221 and the third action surface 222 are not limited further.

[0157] In this way, the design flexibility of the second and / or third contact surfaces 221 and 222 can be improved, and when the contact surfaces are designed as flat surfaces, the manufacturing process is simple and low in cost, and the contact with the roller brush 112 is linear or narrow-surface contact, which can generate a higher local pressure, facilitating the strong scraping of adherent dirt or thick liquid films. When the contact surfaces are designed as curved surfaces, it helps to guide the scraped liquid to flow smoothly along the curved surface to the flow guide structure, reducing splashing or residue.

[0158] As shown in Figure 9 The gap 230 between the base station scraper 220 and the bottom wall of the cleaning tank 211 is configured as a passage for the liquid scraped from the roller brush 112 to enter the cleaning device 100. By providing a gap 230 between the base station scraper 220 and the bottom wall of the cleaning tank 211, a flow passage is provided for the liquid scraped from the roller brush 112 to be discharged or recycled.

[0159] Specifically, when the roller brush 112 rotates in the cleaning tank 211 and performs self-cleaning, the mixture of sewage, dirt and cleaning liquid scraped by the base station scraper 220 falls downward under the action of gravity and centrifugal force. The gap 230 serves as a directional passage, allowing these liquids to quickly flow away from the scraping area and guiding them to the drain at the bottom of the cleaning tank 211 or the suction port 114 of the cleaning device 100, so that they are effectively recycled by the drain system of the cleaning device 100 or the cleaning base station 200. This can prevent the accumulation of dirt scraped from the roller brush 112 at the bottom of the scraper, forming a secondary pollution source, and also prevents liquid from splashing out of the cleaning tank 211, ensuring clean and efficient self-cleaning, while facilitating subsequent cleaning and maintenance of the cleaning tank 211.

[0160] As shown in Figure 10 The base station scraper 220 is provided with mounting portions 225 at both ends, and the cleaning tank 211 is provided with assembly portions (not shown in the figure) that cooperate with the mounting portions 225, and the mounting portions 225 are fixedly connected to the assembly portions.

[0161] By providing mounting portions 225 and assembly portions, the base station scraper 220 can be precisely and stably installed in the cleaning tank 211. By setting the mounting points at both ends of the scraper, the freedom in the axial and circumferential directions of the scraper can be effectively constrained, preventing the base station scraper 220 from shifting or vibrating under the friction generated by the rotation of the roller brush 112, and ensuring that the scraping geometric relationship (such as the acute angle) remains at the designed value for a long time. The fixed connection (such as screw locking, buckle locking, welding, etc.) provides high connection stiffness, making the base station scraper 220 a reliable component of the cleaning tank 211 structure, which can withstand high-intensity mechanical impact that may occur during self-cleaning, ensuring the reliability of the cleaning base station 200 for long-term use.

[0162] For example, the mounting portion 225 is detachably connected with the assembly portion. Through the detachable connection (such as screw connection, elastic buckle, plug-in locking, etc.), it is allowed that when the base station scraping strip 220 is worn, aged or blocked due to long-term use, the user can disassemble, clean or replace it without professional tools or complex operation. In turn, it can reduce the maintenance difficulty of cleaning the base station 200 and prolong the service life of the base station 200.

[0163] Continuing to refer to Figure 10 As shown, the mounting portion 225 can be a flat hole structure, and the assembly portion can be a flat column structure (not shown in the figure).

[0164] By setting the mounting portion 225 as a flat hole structure (such as an oblong hole, a square hole), and setting the assembly portion as a flat column structure (such as a rectangular column, an elliptical column), while achieving plug-in positioning, it can effectively resist the torsion tendency of the base station scraping strip 220 around the axis of the roller brush 112 when it is stressed. The flat mating surface can provide a larger contact area, thereby enhancing the stability of the connection. In addition, this structure is simple to process and convenient to assemble, which can reduce the cost.

[0165] Of course, in other embodiments, the mounting portion 225 and the assembly portion can also be provided in other structures, for example, fastener connection, plug-in connection, etc. to achieve detachable connection. In the embodiments of the present application, the specific structure of the mounting portion 225 and the assembly portion is not limited.
