[0046] During the process of the mop of the roller 21 cleaning the floor, it is difficult to clean the solid garbage scraped by the scraper after it accumulates in the scraper. Although there is a prior art method of controlling the reverse rotation of the roller 21 to remove the garbage on the scraper, the amount of garbage that can be cleaned is limited, and after using for a period of time, the user still needs to remove the scraper to clean the scraper.

[0047] In view of the above problems, the first embodiment of the present invention provides a cleaning mechanism. Please refer to Figures 1 to 8 , the cleaning mechanism includes a cleaning component and a sweeping component 40. The cleaning component includes a bracket 10, a flexible cleaning member 20, and a water scraping member 30. The flexible cleaning member 20 is installed on the bracket 10 and can rotate relative to the bracket 10. The flexible cleaning member 20 can adsorb the sewage and solid garbage on the surface to be cleaned (such as the floor, tabletop, wall surface, etc.), so as to realize the cleaning of the surface to be cleaned.

[0048] The water scraping member 30 is connected to the bracket 10 and abuts against the flexible cleaning member 20. Thus, during the rotation of the flexible cleaning member 20, the water scraping member 30 can scrape the sewage on the flexible cleaning member 20, and the scraped sewage will be collected by the sewage box in the cleaning device. During this process, the solid garbage in the sewage will accumulate on the water scraping member 30. As Figure 3As shown in the figure, the cleaning component 40 provided in the cleaning mechanism in this embodiment includes a cleaning part and a driving part 42. Along the rotation direction of the flexible cleaning part 20, the cleaning part is installed on the side of the wiper part 30 close to the bracket 10 and is connected to the driving part 42. The driving part 42 drives the cleaning part to sweep the garbage on the wiper part 30 outside the wiper part 30. Thus, after a certain amount of garbage accumulates on the wiper part 30, the driving part 42 drives the cleaning part to work to sweep the garbage on the wiper part 30. The swept garbage can be driven by the flexible cleaning part 20 to the surface to be cleaned, and then swept into the dust box of the cleaning device by the middle sweeping mechanism of the cleaning device, so that the cleaning device realizes self-cleaning of the wiper part 30. Without the user disassembling the wiper part 30, the cleaning degree of the wiper part 30 can be maintained, which is convenient to use and provides a good user experience.

[0049] It can be seen that in this embodiment, the cleaning mechanism includes a cleaning component and a cleaning component 40. During the cleaning of the surface to be cleaned, the flexible cleaning part 20 of the cleaning component can rotate relative to the bracket 10. During this process, the flexible cleaning part 20 will adsorb the sewage and garbage on the surface to be cleaned to realize the cleaning of the surface to be cleaned. When the flexible cleaning part 20 adsorbed with sewage and garbage passes by the wiper part 30, the wiper part 30 scrapes off the sewage on the flexible cleaning part 20, and the sewage will be collected by the sewage box installed in the cleaning device, while the garbage will accumulate on the inner side of the wiper part 30 close to the bracket 10. In this regard, to realize the self-cleaning of the wiper part 30, the cleaning mechanism is further provided with a cleaning component 40. The cleaning component 40 includes a cleaning part and a driving part 42. The cleaning part is installed on the side of the wiper part 30 close to the bracket 10. The cleaning part can drive the garbage on the wiper part 30 outside the wiper part 30 under the drive of the driving part 42. This can not only ensure that the garbage on the wiper part 30 can be cleaned up, but also eliminate the need for the user to manually clean the garbage on the wiper part 30, improving the user experience. These swept garbage will fall onto the flexible cleaning part 20. The flexible cleaning part 20 can be driven by the driving part 42 to rotate to carry the garbage to the surface to be cleaned, and then the garbage is swept into the dust box again by the middle sweeping mechanism of the cleaning device. After the cleaning device returns to the base station, the garbage in the dust box can be recycled to the base station. After the cleaning device drives the cleaning mechanism to the base station, the garbage can be directly carried into the base station by the rotating flexible cleaning part 20 for direct recycling at the base station, which is convenient to use. It eliminates the user's maintenance operation on the wiper part 30.

[0050] The cleaning component in this embodiment includes a roller brush 41. The roller brush 41 is connected to the driving component 42 and abuts against the wiper component 30. The driving component 42 drives the roller brush 41 to rotate relative to the wiper component 30 around its own axis. Thus, in this embodiment, by driving the roller brush 41 to rotate through the driving component 42, the garbage on the wiper component 30 can be swept outside the wiper component 30 by the roller brush 41. This cleaning method is not only easy to control, but also because the roller brush 41 always abuts against the wiper component 30, the cleaning strength of the wiper component 30 can be enhanced, and then the cleanliness of the wiper component 30 after being cleaned can be improved.

[0051] The flexible cleaning component 20 in this embodiment includes a driving mechanism, a roller 21, and a flexible cleaning member 22. The driving mechanism is connected to the bracket 10. The driving mechanism can be composed of a connecting seat, a bearing, a motor, and a connecting head. The connecting seat is connected to the bracket 10. The bearing and the motor are sequentially installed on one side of the connecting seat. The connecting head is connected to the output shaft of the motor. The roller 21 is sleeved on the driving mechanism and can rotate around its own axis under the drive of the driving mechanism. The inner wall surface of the roller 21 is specifically inserted into the connecting head. When the output shaft of the motor rotates, it drives the connecting head to drive the roller 21 to rotate around its own axis. The flexible cleaning member 22 is laid on the surface of the roller 21 to rotate under the drive of the roller 21. The flexible cleaning member 22 can include cleaning structures such as a mop and a sponge that can adsorb sewage and garbage.

[0052] The length of the wiper component 30 extends along the axial direction of the roller 21. In some embodiments, at least two roller brushes 41 can be installed along the length direction of the wiper component 30 to sweep the garbage on the wiper component 30 through the at least two roller brushes 41. 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 It can be seen that 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 wiper component 30. The first brush strip 412 protrudes from the surface of the connecting shaft 411 and abuts against the wiper component 30. The first brush strip 412 includes a plurality of bristles 121. Along the axial direction of the connecting shaft 411, the plurality of bristles 121 are arranged from one end of the connecting shaft 411 to the other end. Thus, in this embodiment, only the connecting shaft 411 provided with the first brush strip 412 needs to be installed on the side of the wiper component 30 close to the bracket 10, and the connecting shaft 411 is connected to the driving component 42 to achieve the installation of the roller brush 41, and each component of the wiper component 30 along its own length direction can be abutted and swept by the first brush strip 412, and the assembly difficulty is low. In addition, the structure of the first brush strip 412 composed of a plurality of bristles 121 can also comb and disperse the linear garbage (such as hair, animal hair, silk thread, etc.) accumulated in the wiper component 30, avoiding the difficulty of cleaning due to the tight entanglement of the linear garbage with other garbage.

[0053] In this embodiment, the first brush strip 412 may include at least two (such as two, three, four, five, six, seven, etc., and may also be other numbers greater than seven). Along the circumferential direction of the connecting shaft 411, at least two first brush strips 412 are arranged on the connecting shaft 411, and the adjacent two first brush strips 412 may be arranged at intervals or adjacent to each other. Thus, by abutting at least two first brush strips 412 against the wiper member 30, the cleaning effect of the roller brush 41 on the wiper member 30 can be better.

[0054] In some embodiments, the roller brush 41 in this embodiment may also be a combination of the connecting shaft 411 and the second brush strip. The second brush strip may be a rubber brush in a strip-shaped sheet structure, and the rubber brush is arranged on the surface of the connecting shaft 411 and abuts against the wiper member 30, and the rubber brush extends from one end of the connecting shaft 411 to the other end. Thus, the garbage on the wiper member 30 is cleaned by the rubber brush. The rubber brush can scrape stubborn stains and garbage on the wiper member 30 during the cleaning process, and has a larger contact area with the wiper member 30, and the cleaning effect is better. The second brush strip may also include at least two, and at least two second brush strips are arranged along the circumferential direction of the connecting shaft 411.

[0055] In other embodiments, the roller brush 41 in this embodiment may also be a combination of the connecting shaft 411, the first brush strip 412, and the second brush strip, so as to further improve the cleaning ability of the roller brush 41 on the wiper member 30 by giving play to 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 arranged along the circumferential direction of the connecting shaft 411, at least one second brush strip may be included between the adjacent two first brush strips 412.

[0056] In addition, along the axial direction of the connecting shaft 411, at least one of the first brush strip 412 and the second brush strip in this embodiment includes a first section and a second section. The first section and the second section respectively extend in a spiral shape 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 a 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 driving component 42, the linear objects and other garbage tend to move toward the predetermined position of the connecting shaft 411 along with the rotating first brush bar 412 and / or the second brush bar, making it difficult for the linear objects and other garbage to enter between the end of the connecting shaft 411 and the driving component 42, thereby preventing the linear objects from being entangled with the end of the connecting shaft 411 and the driving component 42 or the linear objects and other garbage from being accumulated between the end of the connecting shaft 411 and the driving component 42, ensuring that the connecting shaft 411 can always operate normally, thereby improving the reliability and service life of the cleaning component 40.

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

[0058] In order to reduce the design difficulty and cost of the cleaning mechanism, the driving component 42 in this embodiment includes a rolling member and a limiting member. The rolling member includes at least two, and the at least two rolling members are respectively connected to the opposite ends of the roller brush 41 and contact the flexible cleaning component 20. Specifically, the opposite ends of the connecting shaft 411 can be connected to at least one rolling member. The flexible cleaning component 20 moves along the first clockwise direction (such as Figure 3 When the roller rotates in the direction indicated by the arrow S1 in the middle, it drives the roller to rotate in the second clockwise direction (such as Figure 3 The first clockwise direction is opposite to the second clockwise direction. The stopper is installed on one side of the rolling element. When the flexible cleaning element 20 rotates in the second clockwise direction, the stopper presses the rolling element tightly against the wiper element 30 to keep it stationary. Figure 3From the perspective shown, the flexible cleaning member 20 rotates counterclockwise to clean the surface to be cleaned (for the convenience of the following description, in this embodiment, the rotation mode of the flexible cleaning member 20 when cleaning the surface to be cleaned is referred to as forward 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 the clockwise direction), and the limiting member presses the rolling member against the position that remains stationary relative to the water scraping member 30. At this time, when the flexible cleaning member 20 cleans the surface to be cleaned, the rolling member does not rotate, so the roller brush 41 does not rotate either, and solid waste will accumulate inside the water scraping member 30. When the waste accumulates to a certain amount, the cleaning device can control the driving mechanism to drive the flexible cleaning member 20 to rotate clockwise (such as Figure 3 the direction indicated by S1 shown

[0059] ). That is, the clockwise direction is the first clockwise direction. Subsequently, for the convenience of distinguishing from the forward rotation operation, the rotation mode at this time is referred to as reverse rotation. At this time, the rolling member will rotate counterclockwise under the drive of the flexible cleaning member 20 (that is, the second clockwise direction is counterclockwise), and the roller brush 41 rotates along the counterclockwise direction with respect to the rolling member, so as to sweep the waste on the water scraping member 30 outside the water scraping member 30. Then, the rotating flexible cleaning member 20 can carry the swept waste to the surface to be cleaned, and then it can be swept into the dust box through the middle sweeping mechanism of the cleaning device.

[0060] As can be seen from the above, when the driving member 42 in this embodiment includes a rolling member and a limiting member, during the forward rotation of the flexible cleaning member 20 to normally perform the cleaning work, the rolling member will remain stationary under the restriction of the limiting member, and solid waste gradually accumulates on the water scraping member 30. When it is necessary to clean the waste deposited on the water scraping member 30, only need to control the flexible cleaning member 20 to rotate in reverse, so as to drive the rolling member to rotate along the second clockwise direction. During the rotation of the rolling member, the roller brush 41 is driven to rotate, so as to sweep the waste on the water scraping member 30 outside the water scraping member 30. The swept waste will be carried to the surface to be cleaned by the flexible cleaning member 20, and then these wastes will be swept into the dust box again or directly recycled by the base station. Thus, in this embodiment, by using the rotational kinetic energy of the flexible cleaning member 20, the rolling member can be driven to drive the roller brush 41 to clean the water scraping member 30, without adding an additional power source, avoiding increasing the energy consumption required by the cleaning device, and avoiding the overall structure of the cleaning mechanism from being too complex, reducing the design difficulty of the cleaning device and reducing the workload of later test verification. It is convenient to assemble and has a low cost.

[0060] Such as Figure 3 and Figure 6It can be seen that the wiper component 30 in this embodiment includes an installation main body 31 and a filter element 32. The installation main 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 installation main body 31 close to the bracket 10. A drain port 312 penetrates 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 port 312. The filter element 32 is used to filter sewage and discharge the filtered sewage to the drain port 312, so that the sewage can flow along the drain port 312 into the sewage box. 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 port 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 on the opposite sides of the first groove 311 and the filter element 32, and the rolling element is located in the installation gap 33. The wiper component 30 in this embodiment is composed of the installation main body 31 and the filter element 32. After the filter element 32 filters and blocks the garbage in the sewage, the sewage flows through the drain port 312 into the sewage box, avoiding blockage of the sewage transmission pipeline and / or the sewage box caused by some garbage during the sewage discharge process. Among them, when the wiper component 30 in this embodiment includes the filter element 32, the rolling element is installed in the installation gap 33 between the inner wall surfaces on the opposite sides of the first groove 311 of the installation main body 31 and the filter element 32. This not only ensures that the roller brush 41 connected to the rolling element can clean the garbage 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] The types of the rolling elements in this embodiment may specifically include ratchets 421, transmission wheels, etc. When the rolling element is a transmission wheel, the limiting element can be a clamping element that can extend to block the transmission wheel. When the rolling element is a ratchet 421, a plurality of ratchet teeth 211 are provided on the outer periphery of the ratchet 421 along its radial direction.

[0062] Among them, as Figure 4 and Figures 6 to 7 , the limiting element includes a spring piece 422. The spring piece 422 is connected to the installation main body 31 and is located on one side of the ratchet 421 along its radial direction. Along the radial direction of the ratchet 421, the spring piece 422 has a first position (such as the position shown in Figure 7 ) where it elastically bounces to abut against the ratchet teeth 211 to block the ratchet 421, and a second position (such as Figure 4 and Figure 6When the elastic piece 422 is in the first position, the ratchet wheel 421 is stationary relative to the wiper member 30. When the elastic piece 422 is in the second position, the ratchet wheel 421 can rotate under the drive of the flexible cleaning member 20. Among them, when the flexible cleaning member 20 rotates in the second clockwise direction, the elastic piece 422 is in the first position. At this time, the ratchet teeth 211 of the ratchet wheel 421 are in contact with the elastic piece 422, and the elastic piece 422 blocks the ratchet wheel 421 from rotating under the drive of the flexible cleaning member 20. When the ratchet wheel 421 rotates in the second clockwise direction, it pushes the elastic piece 422 to bounce from the first position to the second position. When the elastic piece 422 is in the second position, the side of the elastic piece 422 close to the ratchet wheel 421 slides in contact with the outer edge of the ratchet teeth 211 along the radial direction of the ratchet wheel 421, so that the ratchet wheel 421 can rotate under the drive of the flexible cleaning member 20, thereby enabling the ratchet wheel 421 to drive the roller brush 41 to rotate and sweep the garbage on the wiper member 30. In this embodiment, the elastic piece 422 is used to control the timing of the ratchet wheel 421 rotating with the flexible cleaning member 20, so that the roller brush 41 can sweep the garbage on the wiper member 30 when the flexible cleaning member 20 reverses. It is not necessary to design a relatively complex limiting member structure to control the movement trend of the ratchet wheel 421. The control method is simple and convenient, and the installation difficulty and cost of the elastic piece 422 are low.

[0063] The elastic piece 422 may include a metal sheet, a plastic sheet, etc. having a certain elastic deformation function. The elastic piece 422 is preferably a metal sheet that is not easily broken and has good structural strength, so as to improve the service life of the elastic piece 422.

[0064] In this embodiment, the elastic piece 422 includes at least two pieces, and the at least two pieces are respectively arranged in one-to-one correspondence with at least two rolling members, so as to respectively control the movement trends of the at least two rolling members through the at least two elastic pieces 422, and improve the reliability when the driving member 42 drives the roller brush 41 to rotate.

[0065] When the flexible cleaning member 20 in this embodiment reverses to drive the roller brush 41 to rotate and sweep the garbage, as Figure 3 shown, during the process that the flexible cleaning member 20 rotates clockwise to drive the ratchet wheel 421 to rotate counterclockwise, the roller brush 41 can sweep the garbage from the top to the bottom of the wiper member 30 onto the flexible cleaning member 20, and then carry the garbage to the surface to be cleaned in time through the flexible cleaning member 20. In this way, there will be no situation where the garbage falls back onto the wiper member 30 after being swept, and the cleaning efficiency and effect are better. In some embodiment modes, the installation of the limiting member can also be cancelled, so that the flexible cleaning member 20 can drive the roller brush 41 to rotate to sweep the garbage on the wiper member 30 both when it rotates forward and reverses.

[0066] As Figure 4As shown, a plugging structure 313 is provided on the installation main body 31 in this embodiment. The plugging structure 313 includes a second groove 131 and a first through hole 132. The second groove 131 is located on the surface of the installation main body 31 facing away from the filter element 32. The first through hole 132 is disposed through the installation main body 31. The first through hole 132 is located between the second groove 131 and the ratchet wheel 421 and communicates with the installation gap 33. One end of the elastic piece 422 is inserted into the second groove 131, and the other end passes through the first through hole 132 and enters the installation gap 33. The elastic piece 422 finally forms Figure 4 the bent structure shown. Along the radial direction of the ratchet wheel 421, there is a first distance between the end of the elastic piece 422 located in the installation gap 33 and the inner wall surface of the first groove 311. Thus, along the radial direction of the ratchet wheel 421, the elastic piece 422 can be in a first position where it approaches the ratchet wheel 421 and abuts against the ratchet teeth 211 under the action of its own elastic force, and a second position where it moves away and is in sliding contact with the outer edge of the ratchet teeth 211. In this embodiment, by providing the second groove 131 and the first through hole 132 on the installation main body 31, the installation of the elastic piece 422 can be realized without introducing other matching structural parts. The installation is convenient and fast, and the overall structure composed of the wiper member 30 and the driving member 42 is more compact and simple.

[0067] As Figure 5 shown, along the axial direction of the roller brush 41, second through holes 111 communicating with the installation gap 33 are disposed through the side walls on both sides of the first groove 311. The driving member 42 further includes a bushing 423. There are at least two bushings 423. The at least two bushings 423 are respectively sleeved on the opposite ends of the roller brush 41 and are in clearance fit with the second through holes 111. Along the axial direction of the roller brush 41, the rolling elements are located on the side of the bushing 423 away from the second through holes 111. That is, the bushing 423 can be specifically sleeved on the end of the connecting shaft 411 and is located on the side where at least two rolling elements are away from each other. In this embodiment, the roller brush 41 is installed on the wiper member 30 through the clearance fit between the bushing 423 and the second through holes 111, so that the roller brush 41 can rotate relative to the wiper member 30 driven by the rolling elements. The assembly is efficient and convenient. In view of the fact that the bushing 423 is easy to disassemble from the second through holes 111, the maintenance and replacement process of the cleaning assembly 40 is more convenient. At the same time, the bushing 423 can not only ensure the reliable stability of the rotation of the roller brush 41, but also prevent the connecting shaft 411 of the roller brush 41 from directly contacting the inner wall surface of the second through holes 111, thereby reducing the risk of wear and damage of the connecting shaft 411 and extending the service life of the cleaning assembly 40. The bushing 423 also has a certain buffering performance and can absorb the vibration and impact generated during the rotation of the rolling elements and the roller brush 41, ensuring the stability and safety of the cleaning assembly 40.

[0068] In some embodiments, the filter member 32 can be a filter net, and it is only necessary to install the filter net in the first groove 311 of the installation main body 31 and cover the drain port 312. In this embodiment, as Figure 6 shown, the filter member 32 includes slats 321 and filter holes 322 provided on the slats 321. The slats 321 are connected to the inner wall surface of the first groove 311 and cover the drain port 312. Along the radial direction of the roller brush 41, at least a part of the side of the slats 321 close to the flexible cleaning member 20 is located outside the first groove 311 and abuts against the flexible cleaning member 20. Along the axial direction of the roller brush 41, the installation gap 33 is located between the opposite ends of the slats 321 and the inner wall surface of the first groove 311. A third groove 3211 is provided on the side of the slats 321 close to the roller brush 41, and the inner wall surface of the third groove 3211 abuts against the roller brush 41. The filter holes 322 include a plurality of them, and the plurality of filter holes 322 are distributed on the slats 321, and the plurality of filter holes 322 are distributed in the third groove 3211 and penetrate through the slats 321 to communicate with the drain port 312. Thus, during the rotation of the flexible cleaning member 20, after the slats 321 scrape off the sewage and garbage on the flexible cleaning member 20, the filter holes 322 can filter the sewage, thereby preventing the drain port 312 and the sewage box or the transmission pipeline between the drain port 312 and the sewage box from being blocked by garbage. The filtered sewage will be diverted by the filter holes 322 to the drain port 312, and then discharged to the sewage box through the drain port 312, while the solid garbage will accumulate in the third groove 3211. When the flexible cleaning member 20 drives the roller brush 41 to rotate, the solid garbage in the third groove 3211 is swept out by the roller brush 41, and then carried to the surface to be cleaned by the flexible cleaning member 20. When filtering sewage through the slats 321 provided with the filter holes 322 in this embodiment, since the structural strength of the slats 321 is relatively high, the service life of the filter member 32 can be improved. At the same time, by installing the rolling members between the opposite ends of the slats 321 and the inner wall surface of the first groove 311, the overall structural compactness and structural strength between the water scraping member 30 and the cleaning assembly 40 are improved.

[0069] Along the axial direction of the connecting shaft 411, the plurality of filter holes 322 are arranged in at least two rows, and the at least two rows of filter holes 322 are spaced from each other, so as to improve the filtering efficiency of sewage through the at least two rows of filter holes 322.

[0070] Along the length direction of the slats 321, the projected outer contour of the inner wall surface 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 suffered by the roller brush 41 during rotation, reduce the probability of the roller brush 41 being worn out by the slats 321 (that is, the first brush strips 412 and / or the second brush strips on the roller brush 41 are not easily worn out), and improve the stable reliability and service life of the roller brush 41.

[0071] In addition, when the rolling element is located in the installation gap 33 between the end of the slat 321 and the inner wall surface of the first groove 311, in order 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 in this embodiment. Along the axial direction of the connecting shaft 411, the projection outer contour of the bushing 423 and the rolling element can be located within the projection outer contour of the retaining ring, and the retaining ring can rotate with the roller brush 41. Thus, during the process of the roller brush 41 rotating to clean the water scraping member 30, garbage is not easily introduced into the positions of the rolling element and the bushing 423, preventing the bushing 423 and the rolling element from being blocked by garbage and avoiding the blocking rotation phenomenon of the rolling element, thereby improving the stable reliability during the working process of the rolling element, 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 convex column 341, a connecting hole 342, and a locking member. The convex column 341 is provided on the side of the slat 321 close to the drain port 312. Along the axial direction of the convex column 341, the connecting hole 342 is provided 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 convex column 341 together. The locking member can be a screw or a rivet. In this embodiment, the mounting body 31 and the slat 321 are connected together through the connecting structure 34 with the above structure, and the assembly difficulty is low.

[0073] In addition, along the length direction of the slat 321, a plurality of diversion grooves 212 are provided on the side of the slat 321 close to the drain port 312 (as Figure 8 shown), and the plurality of diversion grooves 212 communicate the first groove 311 and the plurality of filter holes 322. Thus, after the sewage is filtered by the filter holes 322, it is diverted to the first groove 311 through the diversion grooves 212, and then flows to the drain port 312 and is transmitted to the sewage box through the transmission pipeline.

[0074] Therefore, for the cleaning mechanism provided in this embodiment, the driving component 42 of the cleaning assembly 40 can reuse the rotational power of the flexible cleaning component 20 to enable the roller brush 41 to clean the water scraping member 30, and utilize the power source of the roller 21 itself (i.e., the power for driving the roller 21 to rotate by the driving mechanism) to complete the self-cleaning function of the water scraping member 30, with low cost and achieving the purpose of truly maintenance-free. The cleaning assembly 40 is convenient to install and simple to maintain. The cleaning device can complete the cleaning of the water scraping member 30 by adopting one of the following two self-cleaning processes:

[0075] The first self-cleaning process: The flexible cleaning component 20 rotates forward to mop the floor → At this time, the ratchet wheel 421 does not rotate under the abutting action of the elastic piece 422 → The roller brush 41 does not rotate → Solid waste will be deposited in the third groove 3211 → After the cleaning device returns to the base station, the flexible cleaning component 20 is driven to rotate reversely → At this time, the ratchet wheel 421 rotates → The roller brush 41 rotates synchronously with the ratchet wheel 421 → The solid waste is carried out by the mop on the roller 21 → The base station self-cleans and recovers the waste.

[0076] The second self-cleaning process: The flexible cleaning component 20 rotates forward to mop the floor → At this time, the ratchet wheel 421 does not rotate → The roller brush 41 does not rotate → Solid waste will be deposited in the third groove 3211 → When the cleaning device turns on the self-cleaning mode, the flexible cleaning component 20 is driven to rotate reversely → At this time, the ratchet wheel 421 rotates → The roller brush 41 rotates synchronously → The solid waste is carried out by the flexible cleaning component 20 onto the surface to be cleaned → The cleaning device sweeps the solid waste and recovers it into the dust box.

[0077] The second embodiment of the present invention also provides a cleaning device, which includes a cleaning mechanism. For the specific structure of the cleaning mechanism, please refer to the content provided in the first embodiment of the present invention, and it will not be elaborated here. The cleaning device can specifically be a floor sweeping robot. As Figure 9 shown, the cleaning device further includes a housing 50. A receiving cavity 51 is provided at the bottom of the housing 50, and 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 the sake of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper" etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations will be made for the spatial relative descriptions used here.

[0079] In addition, it should be noted that using words such as "first", "second" etc. to limit components is only for the convenience of distinguishing the corresponding components. Without further declaration, the above words have no special meaning, so it cannot be understood as a limitation on the protection scope of the present application.

[0080] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
