[0002] Currently, some robotic vacuum cleaners use rotating roller mops to clean floors. Scrapers are installed on the rollers to scrape off wastewater and solid debris from the mop. Wastewater is collected in a wastewater bin within the robot and recycled by the base station upon returning to the robot, thus cleaning up the wastewater. However, the solid debris scraped off by the scrapers accumulates in the scrapers and is difficult to remove completely. Utility Model Content

[0003] The main objective of this application is to provide a cleaning mechanism and cleaning equipment to solve the problem mentioned in the background art where solid waste scraped off by the scraper accumulates in the scraper and is difficult to clean.

[0004] According to one aspect of this application, a cleaning facility is provided, comprising:

[0009] Furthermore, the flexible cleaning component includes a drive mechanism, a roller, and a flexible cleaning element. The drive mechanism is connected to the bracket. The roller is sleeved on the drive mechanism and can rotate around its own axis under the drive of the drive mechanism. The flexible cleaning element is laid on the surface of the roller. The length of the squeegee extends along the axial direction of the roller. The roller brush includes:

[0010] A connecting shaft, the end of which is connected to the driving component and can rotate about its own axis under the drive of the driving component, and the connecting shaft extends along the length direction of the wiper component;

[0012] Furthermore, the driving component includes:

[0013] The rollers include at least two rollers, which are respectively connected to opposite ends of the roller brush and in contact with the flexible cleaning component. When the flexible cleaning component rotates in a first clockwise direction, it drives the rollers to rotate in a second clockwise direction, wherein the first clockwise direction is opposite to the second clockwise direction.

[0014] A limiting member is installed on one side of the rolling member. When the flexible cleaning component rotates in the second clockwise direction, the limiting member presses the rolling member against it until it remains stationary relative to the wiping component.

[0015] Furthermore, the wiper component includes:

[0016] The mounting body is connected to the bracket and abuts against the flexible cleaning component. Along the rotation direction of the flexible cleaning component, the mounting body has a first groove on the side near the bracket, and a drain outlet is provided through the side wall of the first groove away from the bracket.

[0017] A filter element is connected to the inner wall of the first groove and covers the drain outlet. The filter element is used to filter sewage and discharge the filtered sewage to the drain outlet. Along the rotation direction of the flexible cleaning component, the roller brush is located on the side of the filter element away from the drain outlet and abuts against the filter element. Along the axial direction of the roller brush, there is an installation gap between the inner wall surfaces of the first groove on opposite sides and the filter element, and the roller element is located within the installation gap.

[0018] Furthermore, the rolling element includes a ratchet, the ratchet having a plurality of ratchet teeth arranged along its radial outer periphery, and the limiting element includes:

[0019] A spring plate, which is connected to the mounting body and located on one side of the ratchet along its own radial direction, has a first position where it springs to abut against the ratchet tooth to block the ratchet under its own elasticity, and a second position where it springs to slide into contact with the outer edge of the ratchet along its own radial direction.

[0020] When the flexible cleaning component rotates in the second clockwise direction, the spring is located in the first position, and when the ratchet rotates in the second clockwise direction, it pushes the spring from the first position to the second position.

[0021] Furthermore, the mounting body is provided with a plug-in structure, the plug-in structure comprising:

[0022] The second groove is located on the surface of the mounting body opposite to the filter element;

[0027] A slat, along the radial direction of the roller brush, has at least a portion of its side near the flexible cleaning component located outside the first groove and abutting against the flexible cleaning component. Along the axial direction of the roller brush, the mounting gap is located between the opposite ends of the slat and the inner wall surface of the first groove. A third groove is provided on the side of the slat near the roller brush, and the inner wall surface of the third groove abuts against the roller brush.

[0028] The filter holes include multiple filter holes, which are distributed within the third groove and pass through the strip to communicate with the drain outlet.

[0029] On the other hand, this application also provides a cleaning device that includes the aforementioned cleaning mechanism.

[0030] In this application, the cleaning mechanism includes a cleaning component and a sweeping component. During the cleaning process, the flexible cleaning part of the cleaning component can rotate relative to the support. During this process, the flexible cleaning part absorbs wastewater and debris from the surface to be cleaned. When the flexible cleaning part, which has absorbed wastewater and debris, passes the squeegee, the squeegee scrapes off the wastewater, which is collected by a wastewater box installed in the cleaning equipment. Debris accumulates on the inner side of the squeegee near the support. To achieve self-cleaning of the squeegee, the cleaning mechanism also includes a sweeping component, which includes a sweeping part and a driving part. The sweeping part is installed on the side of the squeegee near the support. Driven by the driving part, the sweeping part sweeps the debris off the squeegee, ensuring that the debris is thoroughly cleaned and eliminating the need for manual cleaning, thus improving the user experience. The swept-up debris will fall onto the flexible cleaning component. A drive mechanism rotates this component, carrying the debris to the surface to be cleaned. The cleaning device's central sweeping mechanism then sweeps the debris back into the dustbin. Once the cleaning device returns to the base station, the debris in the dustbin is collected and returned to the base station. Alternatively, after the cleaning device moves the cleaning mechanism to the base station, the rotating flexible cleaning component can directly carry the debris to the base station for direct collection, offering convenient operation.

[0046] When the roller mop 21 is cleaning the floor, the solid debris scraped off by the scraper accumulates in the scraper and is difficult to clean. Although existing technology can control the roller 21 to reverse and remove the debris from the scraper, the amount of debris that can be removed is limited. After a period of use, the user still needs to remove the scraper to clean it.

[0047] To address the aforementioned problems, the first embodiment of this utility model provides a cleaning mechanism, please refer to [link / reference]. Figures 1 to 8 The cleaning mechanism includes a cleaning component and a sweeping component 40. The cleaning component includes a support 10, a flexible cleaning part 20, and a squeegee part 30. The flexible cleaning part 20 is mounted on the support 10 and can rotate relative to the support 10. The flexible cleaning part 20 can absorb sewage and solid waste on the surface to be cleaned (such as the floor, table, wall, etc.), thereby achieving the cleaning of the surface to be cleaned.

[0048] The squeegee component 30 is connected to the bracket 10 and abuts against the flexible cleaning component 20. Thus, during the rotation of the flexible cleaning component 20, the squeegee component 30 can scrape off the wastewater from the flexible cleaning component 20, and the scraped wastewater will be collected in the wastewater box of the cleaning equipment. During this process, solid waste in the wastewater will accumulate on the squeegee component 30. Figure 3As shown, the cleaning component 40 in this embodiment includes a cleaning component and a driving component 42. Along the rotation direction of the flexible cleaning component 20, the cleaning component is installed on the side of the wiping component 30 near the bracket 10 and connected to the driving component 42. The driving component 42 drives the cleaning component to sweep the debris on the wiping component 30 to the outside of the wiping component 30. Thus, after a certain amount of debris accumulates on the wiping component 30, the driving component 42 drives the cleaning component to clean the debris. The cleaned debris can be carried by the flexible cleaning component 20 to the surface to be cleaned, and then swept into the dust box of the cleaning device by the central sweeping mechanism. This allows the cleaning device to achieve self-cleaning of the wiping component 30, maintaining its cleanliness without requiring the user to disassemble it, providing convenience and a good user experience.

[0049] As can be seen, in this embodiment, the cleaning mechanism includes a cleaning component and a sweeping component 40. During the cleaning process, the flexible cleaning component 20 of the cleaning component can rotate relative to the support 10. During this process, the flexible cleaning component 20 will absorb sewage and debris on the surface to be cleaned. When the flexible cleaning component 20, which has absorbed sewage and debris, passes the squeegee 30, the squeegee 30 scrapes off the sewage on the flexible cleaning component 20. The sewage will be collected by the sewage box installed in the cleaning equipment, while the debris will accumulate on the inner side of the squeegee 30 near the support 10. To achieve self-cleaning of the squeegee 30, the cleaning mechanism is also provided with a sweeping component 40, which includes a sweeping component and a driving component 42. The sweeping component is installed on the side of the squeegee 30 near the support 10. Driven by the drive unit 42, the sweeping component can sweep the debris from the wiper component 30 to the outside of the wiper component 30. This not only ensures that the debris on the wiper component 30 is cleaned thoroughly, but also eliminates the need for manual cleaning by the user, improving the user experience. The swept debris will fall onto the flexible cleaning component 20, which can be rotated by the drive unit 42 to carry the debris to the surface to be cleaned. Then, the cleaning device's sweeping mechanism will sweep the debris back into the dustbin. After the cleaning device returns to the base station, the debris in the dustbin can be collected and returned to the base station. Alternatively, after the cleaning device drives the cleaning mechanism to the base station, the rotating flexible cleaning component 20 can directly carry the debris to the base station for direct collection, offering convenience and eliminating the need for user maintenance of the wiper component 30.

[0050] The cleaning component in this embodiment includes a roller brush 41, which is connected to a drive component 42 and abuts against the wiping component 30. The drive component 42 drives the roller brush 41 to rotate relative to the wiping component 30 around its own axis. Thus, by driving the roller brush 41 to rotate, the roller brush 41 can sweep the debris on the wiping component 30 to the outside of the wiping component 30. This cleaning method is not only easy to control, but also enhances the cleaning power of the wiping component 30 because the roller brush 41 is always in contact with the wiping component 30, thereby improving the cleanliness of the wiping component 30 after cleaning.

[0051] The flexible cleaning component 20 in this embodiment includes a drive mechanism, a roller 21, and a flexible cleaning element 22. The drive mechanism is connected to the support 10 and may consist of a connecting seat, bearings, a motor, and a connector. The connecting seat is connected to the support 10, and the bearings and motor are sequentially installed on one side of the connecting seat. The connector is connected to the output shaft of the motor. The roller 21 is sleeved on the drive mechanism and can rotate around its own axis under the drive of the drive mechanism. The inner wall surface of the roller 21 is specifically inserted into the connector. When the output shaft of the motor rotates, the drive connector drives the roller 21 to rotate around its own axis. The flexible cleaning element 22 is laid on the surface of the roller 21 to rotate under the drive of the roller 21. The flexible cleaning element 22 may include a mop, sponge, or other cleaning structure that can absorb sewage and garbage.

[0052] The length of the wiping component 30 extends along the axial direction of the roller 21. In some embodiments, at least two roller brushes 41 may be installed along the length of the wiping component 30 to sweep away debris from the wiping component 30. To reduce the assembly difficulty of the cleaning assembly 40 and improve the assembly efficiency of the entire cleaning mechanism, combined with... Figures 3 to 7 As can be seen, the roller brush 41 in this embodiment includes a connecting shaft 411 and a first brush strip 412. The end of the connecting shaft 411 is connected to the driving component 42 and can rotate around its own axis under the drive of the driving component 42, and the connecting shaft 411 extends along the length direction of the wiping component 30. The first brush strip 412 protrudes from the surface of the connecting shaft 411 and abuts against the wiping component 30. The first brush strip 412 includes multiple bristles 121, which are arranged from one end of the connecting shaft 411 to the other end along the axial direction of the connecting shaft 411. Therefore, in this embodiment, the roller brush 41 can be installed simply by installing the connecting shaft 411 with the first brush strip 412 on the side of the wiping component 30 near the bracket 10 and connecting the connecting shaft 411 to the driving component 42. This ensures that all components of the wiping component 30 along its own length direction can be abutted and cleaned by the first brush strip 412, making assembly simple. In addition, the first brush bar 412 structure, which consists of multiple bristles 121, can comb and break up the filamentous debris (such as hair, animal hair, and threads) gathered in the wiping component 30, preventing the filamentous debris from being difficult to sweep away due to being tightly entangled with other debris.

[0053] In this embodiment, the first brush strip 412 may include at least two (such as two, three, four, five, six, seven, or other quantities greater than seven), arranged along the circumference of the connecting shaft 411. Adjacent first brush strips 412 may be spaced apart or arranged adjacently. Therefore, by having at least two first brush strips 412 abut against the wiping component 30, the roller brush 41 can achieve a better cleaning effect on the wiping component 30.

[0054] In some embodiments, the roller brush 41 in this embodiment can also be a combination of a connecting shaft 411 and a second brush strip. The second brush strip can be a strip-shaped, sheet-like rubber brush, which is disposed on the surface of the connecting shaft 411 and abuts against the wiping component 30, extending from one end of the connecting shaft 411 to the other. This allows the rubber brush to clean debris from the wiping component 30. During the cleaning process, the rubber brush can scrape away stubborn stains and debris from the wiping component 30, and has a larger contact area with the wiping component 30, resulting in better cleaning. The second brush strip may also include at least two strips, arranged circumferentially along the connecting shaft 411.

[0055] In other embodiments, the roller brush 41 in this embodiment may also be a combination of a connecting shaft 411, a first brush strip 412, and a second brush strip, thereby further improving the cleaning ability of the roller brush 41 on the wiping component 30 by leveraging the respective cleaning advantages of the first brush strip 412 and the second brush strip. When both the first brush strip 412 and the second brush strip include at least two strips arranged circumferentially along the connecting shaft 411, at least one second brush strip may be included between two adjacent first brush strips 412.

[0056] Furthermore, along the axial direction of the connecting shaft 411, at least one of the first brush bar 412 and the second brush bar in this embodiment includes a first segment and a second segment. The first segment and the second segment extend spirally from opposite ends of the connecting shaft 411 to a predetermined position between the opposite ends of the connecting shaft 411 and converge at the predetermined position to form a V-shaped structure. The predetermined position may be located at the middle position between the opposite ends of the connecting shaft 411 or at the position between the middle position and the end of the connecting shaft 411. Therefore, when the connecting shaft 411 drives at least one of the first brush bar 412 and the second brush bar to rotate under the drive of the drive component 42, linear objects and other debris tend to move towards a predetermined position on the connecting shaft 411 as the first brush bar 412 and / or the second brush bar rotates. This makes it difficult for linear objects and other debris to enter between the end of the connecting shaft 411 and the drive component 42, thereby preventing linear objects from getting tangled between the end of the connecting shaft 411 and the drive component 42 or from accumulating between the end of the connecting shaft 411 and the drive component 42. This ensures that the connecting shaft 411 can always operate normally, improving the reliability and service life of the cleaning assembly 40.

[0057] In some embodiments, the drive component 42 in this embodiment may include a motor and a transmission connector. The transmission connector may be connected to the output shaft of the motor and the connecting shaft 411 of the roller brush 41 so as to drive the roller brush 41 to rotate and clean the wiping component 30.

[0058] To reduce the design difficulty and cost of the cleaning mechanism, the driving component 42 in this embodiment includes rolling elements and limiting elements. At least two rolling elements are connected to opposite ends of the roller brush 41 and contact the flexible cleaning component 20. Specifically, at least one rolling element can be connected to opposite ends of the connecting shaft 411. The flexible cleaning component 20 moves along a first clockwise direction (e.g., ...). Figure 3 When the direction indicated by the middle arrow S1 rotates, it drives the rolling element to rotate in the second clockwise direction (e.g., Figure 3 Rotating in the direction indicated by the middle arrow S2, the first clockwise direction is opposite to the second clockwise direction. A limiting member is installed on one side of the rolling element. When the flexible cleaning component 20 rotates in the second clockwise direction, the limiting member presses the rolling element against the relative wiping component 30, keeping it stationary. Normally, during the cleaning process of the cleaning equipment, from... Figure 3From the angle shown, the flexible cleaning component 20 rotates counterclockwise to clean the surface to be cleaned (for ease of description below, this embodiment refers to the rotation of the flexible cleaning component 20 when cleaning the surface as clockwise rotation). At this time, the counterclockwise direction is the second clockwise direction (if viewed from the other end of the roller 21, the second clockwise direction is clockwise). The limiting member presses the rolling component against the wiping component 30 to a position where it remains stationary. At this time, the rolling component does not rotate when the flexible cleaning component 20 cleans the surface, and therefore the roller brush 41 also does not rotate, allowing solid waste to accumulate inside the wiping component 30. When the waste accumulates to a certain amount, the cleaning equipment can control the drive mechanism to drive the flexible cleaning component 20 clockwise (e.g., ...). Figure 3 Rotate in the direction indicated by S1 (i.e., clockwise is the first clockwise direction, and for ease of distinction from forward rotation, this rotation method is called reverse rotation). At this time, the rolling element will rotate counterclockwise under the drive of the flexible cleaning component 20 (i.e., the second clockwise direction is counterclockwise). The roller brush 41 rotates the rolling element counterclockwise to sweep the debris on the wiping component 30 to the outside of the wiping component 30. The rotating flexible cleaning component 20 can carry the swept debris to the surface to be cleaned, and then sweep it into the dust box by the middle sweeping mechanism of the cleaning equipment.

[0059] As can be seen from the above, when the driving component 42 in this embodiment includes a rolling element and a limiting element, during the normal cleaning operation of the flexible cleaning component 20, the rolling element will remain stationary under the restriction of the limiting element, and solid waste will gradually accumulate on the wiping component 30. When it is necessary to clean the waste deposited on the wiping component 30, it is only necessary to control the flexible cleaning component 20 to reverse, thereby driving the rolling element to rotate in the second clockwise direction. During the rotation of the rolling element, the roller brush 41 will rotate, thereby sweeping the waste on the wiping component 30 to the outside of the wiping component 30. The swept-away waste will be carried by the flexible cleaning component 20 to the surface to be cleaned, and then these wastes can be swept back into the dust box or directly recycled by the base station. Thus, this embodiment utilizes the rotational kinetic energy of the flexible cleaning component 20 to drive the rolling element to drive the roller brush 41 to clean the wiping component 30 without adding an additional power source, avoiding increasing the energy consumption required by the cleaning equipment, and avoiding an overly complex overall structure of the cleaning mechanism, reducing the design difficulty of the cleaning equipment and the workload of subsequent testing and verification, making assembly convenient and cost-effective.

[0060] like Figure 3 as well as Figure 6As can be seen, the wiping component 30 in this embodiment includes a mounting body 31 and a filter element 32. The mounting body 31 is connected to the bracket 10 and abuts against the flexible cleaning component 20. Along the rotation direction of the flexible cleaning component 20, a first groove 311 is provided on the side of the mounting body 31 closest to the bracket 10, and a drain outlet 312 is provided through the side wall of the first groove 311 away from the bracket 10. The filter element 32 is connected to the inner wall surface of the first groove 311 and covers the drain outlet 312. The filter element 32 is used to filter sewage and discharge the filtered sewage to the drain outlet 312 so that the sewage can flow into the sewage box along the drain outlet 312. Along the rotation direction of the flexible cleaning component 20, the roller brush 41 is located on the side of the filter element 32 away from the drain outlet 312 and abuts against the filter element 32. Along the axial direction of the roller brush 41, there is an installation gap 33 between the inner wall surfaces of the first groove 311 on opposite sides and the filter element 32, and the roller element is located within the installation gap 33. In this embodiment, the wiper component 30 consists of a mounting body 31 and a filter element 32. The filter element 32 filters and blocks debris in the sewage, allowing the sewage to flow through the drain outlet 312 to the sewage box, thus preventing some debris from clogging the sewage transmission pipe and / or the sewage box during sewage discharge. In this embodiment, when the wiper component 30 includes the filter element 32, the rolling element is installed in the mounting gap 33 between the inner wall surfaces of the opposite sides of the first groove 311 of the mounting body 31 and the filter element 32. This not only ensures that the roller brush 41 connected to the rolling element can clean the debris accumulated in the wiper component 30, but also makes the overall assembly of the cleaning component 40 and the wiper component 30 more compact and reliable, saving installation space.

[0061] In this embodiment, the type of rolling element may specifically include a ratchet 421, a drive wheel, etc. When the rolling element is a drive wheel, the limiting element can be a snap-fit ​​element that can extend and retract to stop the drive wheel. When the rolling element is a ratchet 421, the ratchet 421 has multiple ratchet teeth 211 arranged on its radial outer periphery.

[0062] Among them, such as Figure 4 as well as Figures 6 to 7 The limiting component includes a spring piece 422, which is connected to the mounting body 31 and located on one side of the ratchet 421 along its own radial direction. Along the radial direction of the ratchet 421, the spring piece 422 has the ability to spring back to a first position (e.g., under its own elastic force) to abut against the ratchet tooth 211 to block the ratchet 421. Figure 7 The position shown), and a second position having a spring-loaded position that slides into contact with the outer edge of the ratchet 421 along its own radial direction (as shown). Figure 4 and Figure 6(As shown in the diagram). When the spring plate 422 is in the first position, the ratchet 421 is stationary relative to the wiping component 30. When the spring plate 422 is in the second position, the ratchet 421 can rotate under the drive of the flexible cleaning component 20. Specifically, when the flexible cleaning component 20 rotates in the second clockwise direction, the spring plate 422 is in the first position. At this time, the ratchet tooth 211 of the ratchet 421 abuts against the spring plate 422, and the spring plate 422 prevents the ratchet 421 from rotating under the drive of the flexible cleaning component 20. When the ratchet 421 rotates in the second clockwise direction, it pushes the spring plate 422 from the first position to the second position. When the spring plate 422 is in the second position, the side of the spring plate 422 near the ratchet 421 slides and contacts the ratchet tooth 211 along the radial outer edge of the ratchet 421, so that the ratchet 421 can rotate under the drive of the flexible cleaning component 20. This allows the ratchet 421 to sweep away the debris on the wiping component 30 while driving the roller brush 41 to rotate. In this embodiment, the timing of the ratchet 421 rotating with the rotation of the flexible cleaning component 20 is controlled by the spring piece 422, so that the roller brush 41 can clean the debris on the squeegee component 30 when the flexible cleaning component 20 is reversed. The movement trend of the ratchet 421 can be controlled without designing a complex limiting component structure. The control method is simple and convenient, and the installation of the spring piece 422 is easy and low-cost.

[0063] The spring sheet 422 may include a metal sheet, plastic sheet, etc., with a certain elastic deformation function. The spring sheet 422 is preferably a metal sheet that is not easy to break and has good structural strength, thereby improving the service life of the spring sheet 422.

[0064] In this embodiment, the spring sheet 422 includes at least two pieces, each of which is respectively arranged in correspondence with at least two rolling elements. Thus, the movement trend of at least two rolling elements can be controlled by the at least two spring sheets 422, thereby improving the reliability of the drive component 42 when driving the roller brush 41 to rotate.

[0065] In this embodiment, when the flexible cleaning component 20 reverses and drives the roller brush 41 to rotate and sweep away debris, such as Figure 3 As shown, during the clockwise rotation of the flexible cleaning component 20, which drives the ratchet 421 to rotate counterclockwise, the roller brush 41 can sweep debris from the top to the bottom of the squeegee 30 onto the flexible cleaning component 20. The flexible cleaning component 20 then promptly carries the debris to the surface to be cleaned. This method prevents debris from falling back onto the squeegee 30 after being swept, resulting in better cleaning efficiency and effectiveness. In some embodiments, the limiting member can be omitted, allowing the flexible cleaning component 20 to drive the roller brush 41 to rotate and sweep debris from the squeegee 30 in both clockwise and counterclockwise directions.

[0066] like Figure 4As shown, the mounting body 31 in this embodiment is provided with a plug-in structure 313, which includes a second groove 131 and a first through hole 132. The second groove 131 is located on the surface of the mounting body 31 facing away from the filter element 32. The first through hole 132 is disposed through the mounting body 31, located between the second groove 131 and the ratchet 421, and communicates with the mounting gap 33. One end of the spring piece 422 is inserted into the second groove 131, and the other end passes through the first through hole 132 into the mounting gap 33. The spring piece 422 is finally formed into a shape that is not visible in the image. Figure 4 The bent structure is shown. Along the radial direction of the ratchet 421, the end of the spring piece 422 located within the mounting gap 33 has a first distance between it and the inner wall of the first groove 311. Thus, along the radial direction of the ratchet 421, the spring piece 422 can approach the ratchet 421 and abut against the ratchet tooth 211 at a first position under its own elastic force, and move away to a second position where it slides into contact with the outer edge of the ratchet tooth 211. In this embodiment, by providing the second groove 131 and the first through hole 132 in the mounting body 31, the spring piece 422 can be installed without introducing other mating structural components, making installation convenient and quick, and making the overall structure of the wiper component 30 and the drive component 42 more compact and concise.

[0067] like Figure 5 As shown, along the axial direction of the roller brush 41, the sidewalls of the first groove 311 on both sides are provided with second through holes 111 communicating with the mounting gap 33. The driving component 42 also includes bushings 423. There are at least two bushings 423, which are respectively sleeved on the opposite ends of the roller brush 41 and have a clearance fit with the second through holes 111. Along the axial direction of the roller brush 41, the rolling element is located on the side of the bushing 423 away from the second through hole 111, that is, the bushing 423 can be specifically sleeved on the end of the connecting shaft 411 and located on the side of at least two rolling elements away from each other. In this embodiment, the roller brush 41 is installed on the wiper component 30 by the clearance fit between the bushing 423 and the second through hole 111, and the roller brush 41 can rotate relative to the wiper component 30 under the drive of the rolling element. The assembly is efficient and convenient, and since the bushing 423 is easy to remove from the second through hole 111, the maintenance and replacement process of the cleaning component 40 is more convenient. Meanwhile, the bushing 423 not only ensures the reliable stability of the roller brush 41's rotation, but also prevents the connecting shaft 411 of the roller brush 41 from directly contacting the inner wall of the second through hole 111, thereby reducing the risk of wear damage to the connecting shaft 411 and extending the service life of the cleaning assembly 40. The bushing 423 also has a certain buffering performance, which can absorb the vibration and impact generated during the rotation of the rolling parts and the roller brush 41, ensuring the stability and safety of the cleaning assembly 40.

[0068] In some embodiments, the filter element 32 can be a filter screen, which is installed in the first groove 311 of the mounting body 31 and covers the drain outlet 312. In this embodiment, as... Figure 6 As shown, the filter element 32 includes a slat 321 and filter holes 322 disposed on the slat 321. The slat 321 is connected to the inner wall of the first groove 311 and covers the drain outlet 312. Along the radial direction of the roller brush 41, at least part of the side of the slat 321 near the flexible cleaning component 20 is located outside the first groove 311 and abuts against the flexible cleaning component 20. Along the axial direction of the roller brush 41, the mounting gap 33 is located between the opposite ends of the slat 321 and the inner wall of the first groove 311. A third groove 3211 is provided on the side of the slat 321 near the roller brush 41, and the inner wall of the third groove 3211 abuts against the roller brush 41. Multiple filter holes 322 are distributed on the slat 321, and are also distributed within the third groove 3211, penetrating the slat 321 and communicating with the drain outlet 312. Therefore, during the rotation of the flexible cleaning component 20, the slats 321 scrape off the sewage and debris from the flexible cleaning component 20, and the filter holes 322 filter the sewage, thus preventing debris from clogging the drain outlet 312 and the sewage box, or the transmission pipe located between the drain outlet 312 and the sewage box. The filtered sewage will be guided by the filter holes 322 to the drain outlet 312, and then discharged into the sewage box through the drain outlet 312, while solid debris will accumulate in the third groove 3211. When the flexible cleaning component 20 drives the roller brush 41 to rotate, the roller brush 41 sweeps out the solid debris in the third groove 3211, and then carries it to the surface to be cleaned by the flexible cleaning component 20. In this embodiment, when sewage is filtered by slats 321 with filter holes 322, the high structural strength of the slats 321 can improve the service life of the filter element 32. At the same time, the rolling element is installed between the opposite ends of the blade 321 and the inner wall of the first groove 311, which improves the compactness and structural strength of the overall structure between the wiper component 30 and the cleaning assembly 40.

[0069] Along the axial direction of the connecting shaft 411, a plurality of filter holes 322 are arranged in at least two rows, and the at least two rows of filter holes 322 are spaced apart from each other, thereby improving the filtration efficiency of wastewater through the at least two rows of filter holes 322.

[0070] Along the length of the slat 321, the projected outer contour of the inner wall of the third groove 3211 is arc-shaped. The arc-shaped third groove 3211 can not only collect more garbage, but also reduce the resistance encountered by the roller brush 41 during rotation, reduce the probability of the roller brush 41 being worn and failing by the slat 321 (that is, the first brush strip 412 and / or the second brush strip on the roller brush 41 are not easily worn and damaged), and improve the stability, reliability and service life of the roller brush 41.

[0071] Furthermore, in this embodiment, when the rolling element is located within the installation gap 33 between the end of the slat 321 and the inner wall of the first groove 311, to improve the working stability of the rolling element, a retaining ring can be provided between the rolling element and the first brush strip 412 and / or the second brush strip. Along the axial direction of the connecting shaft 411, the projected outer contour of the bushing 423 and the rolling element can be located within the projected outer contour of the retaining ring, allowing the retaining ring to rotate with the roller brush 41. Thus, during the rotation of the roller brush 41 to clean the squeegee component 30, debris is less likely to enter the rolling element and bushing 423, preventing debris from clogging the bushing 423 and the rolling element, avoiding the rolling element from becoming stuck, thereby improving the stability and reliability of the rolling element during operation, reducing the maintenance frequency of the cleaning assembly 40, and increasing the service life of the cleaning assembly 40.

[0072] A connecting structure 34 is provided between the mounting body 31 and the slat 321, such as Figure 8 As shown, the connecting structure 34 includes a protruding post 341, a connecting hole 342, and a locking member. The protruding post 341 is located on the side of the strip 321 near the drain outlet 312. Along the axial direction of the protruding post 341, the connecting hole 342 is located at the bottom of the first groove 311. The locking member passes through the connecting hole 342 to lock the mounting body 31 and the protruding post 341 together. The locking member can be a screw or a rivet. In this embodiment, the mounting body 31 and the strip 321 are connected together through the connecting structure 34 described above, which reduces assembly difficulty.

[0073] In addition, along the length of the slat 321, a plurality of guide grooves 212 are provided on the side of the slat 321 near the drain outlet 312 (e.g. Figure 8 As shown, multiple guide channels 212 connect the first groove 311 and multiple filter holes 322. Thus, after being filtered by the filter holes 322, the sewage is guided through the guide channels 212 into the first groove 311, and then flows to the drain outlet 312, and is then transported to the sewage box through the transmission pipe.

[0074] Therefore, the cleaning mechanism provided in this embodiment, whose sweeping component 40's driving component 42 can reuse the rotational power of the flexible cleaning component 20 to enable the roller brush 41 to sweep the wiping component 30, utilizes the roller 21's own power source (i.e., the power that drives the roller 21 to rotate) to complete the self-cleaning function of the wiping component 30, resulting in low cost and achieving true maintenance-free operation. The sweeping component 40 is easy to install and maintain. The cleaning equipment can use one of the following two self-cleaning processes to clean the wiping component 30:

[0075] First self-cleaning process: Flexible cleaning component 20 rotates forward to mop the floor → At this time, ratchet 421 does not rotate under the action of spring piece 422 → roller brush 41 does not rotate → Solid waste will be deposited in the third groove 3211 → After the cleaning equipment returns to the base station, it drives the flexible cleaning component 20 to rotate in reverse → At this time, ratchet 421 rotates → roller brush 41 rotates synchronously with ratchet 421 → Solid waste is carried out by the mop on roller 21 → Base station self-cleaning to collect waste.

[0076] Second self-cleaning process: Flexible cleaning component 20 rotates forward to mop the floor → at this time, ratchet 421 does not rotate → roller brush 41 does not rotate → solid waste will be deposited in the third groove 3211 → the cleaning equipment starts the self-cleaning mode and drives the flexible cleaning component 20 to rotate in reverse → at this time, ratchet 421 rotates → roller brush 41 rotates synchronously → solid waste is carried out by the flexible cleaning component 20 to the surface to be cleaned → the cleaning equipment sweeps up the solid waste and collects it into the dust box.

[0077] The second embodiment of this utility model also provides a cleaning device, which includes a cleaning mechanism. For details on the structure of the cleaning mechanism, please refer to the description provided in the first embodiment of this utility model; it will not be repeated here. The cleaning device may specifically be a robotic vacuum cleaner. Figure 9 As shown, the cleaning device also includes a housing 50, and a receiving cavity 51 is provided at the bottom of the housing 50. The cleaning mechanism is installed in the receiving cavity 51 so that the flexible cleaning component 20 of the cleaning mechanism can clean the surface to be cleaned.

[0078] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0079] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0080] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
