Description

Technical Field

[0001] This application belongs to the field of cleaning equipment technology, and more specifically, relates to a roller module and a cleaning robot. Background Technology

[0002] Cleaning robots with roller mops are more widely used due to their efficient mopping capabilities. When working, these cleaning robots usually need to continuously spray water onto the roller mop through the spray nozzles via an internal water tank and water pump to keep the mop moist, thereby achieving effective floor cleaning.

[0003] In related technologies, the water spray nozzles of most water spray devices adopt a direct spray method, perpendicular to the roller surface or facing the direction of roller rotation. When the cleaning robot is working, the roller mop will pick up dust, hair, stains, and other debris after cleaning the floor. As the roller rotates, these stains attached to the mop surface will directly contact and clog the water spray nozzles. Once the water spray nozzles are clogged, it will result in poor water flow or no water flow at all, seriously affecting the wetting and cleaning effect of the roller mop, thus significantly reducing the overall mopping performance of the machine and resulting in a poor user experience. Summary of the Invention

[0004] The purpose of this application is to provide a roller module and a cleaning robot to solve the technical problem in the prior art where the water spray holes of the cleaning robot are easily clogged by stains on the roller mop.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a roller module, comprising:

[0006] roller brush holder,

[0007] A roller mop is mounted on the roller brush bracket;

[0008] The shower assembly is mounted on the roller brush bracket. The shower assembly has spray holes and anti-clogging baffles. The spray holes are used to spray water onto the roller mop. The anti-clogging baffles are interference-fitted with the roller mop. Along the rotation direction of the roller mop when cleaning the floor, the anti-clogging baffles are located upstream of the spray holes.

[0051] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0052] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0053] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0055] This application provides a roller module 700, see reference. Figures 1 to 3 The system includes a roller brush holder 10, a roller brush assembly 20, a shower head assembly 30, and a scraper 41. The roller brush assembly 20 includes a roller mop 21, which is mounted on the roller brush holder 10. The shower head assembly 30 is fixed to the roller brush holder 10 and has spray holes 32 for supplying liquid to the roller mop 21 after cleaning the floor. The scraper 41 is mounted on the roller brush holder 10 and is interference-fitted with the roller mop 21. Along the direction of rotation of the roller mop 21 when cleaning the floor, the scraper 41 is located downstream of the shower head assembly 30 and is used to scrape away dirt from the roller mop 21 after it has been moistened by the shower head assembly 30.

[0056] The interference fit between the scraper 41 and the roller mop 21 means that the scraping edge 411 of the scraper 41 penetrates into the natural outline of the pile of the roller mop 21. The scraper 41 can continuously apply pressure to the roller mop 21. When the roller mop 21 rotates, the wet and dirty roller mop 21 is forcibly squeezed as it passes through the scraper 41.

[0057] As the cleaning robot moves forward to clean the floor, the roller mop 21 rotates at its bottom, wiping away stains. After the soiled roller mop 21 rotates off the floor, it first passes through the shower assembly 30, which sprays water onto the roller mop 21, wetting the soiled portion. Next, the wet, soiled mop passes through the interference-fitted scraper 41, which scrapes away the dissolved dirt and water from the roller mop 21. Thus, the roller mop 21 is clean again after one rotation and can continue cleaning the floor.

[0058] Compared to the traditional cleaning process of spraying liquid, mopping, and squeegee scraping, the roller module 700 provided in this application embodiment allows for a different cleaning method. After the roller mop 21 has been mopped, the shower assembly 30 sprays clean water onto the soiled roller mop 21, and then the squeegee 41 scrapes away the dirty water from the roller mop 21. Because the roller mop 21 only comes into contact with the ground after the squeegee 41 scrapes away the dirt, the portion of the roller mop 21 in contact with the ground is just dried by the squeegee 41, with moderate humidity, leaving fewer water stains on the ground during mopping. Before the squeegee 41 scrapes away the stains, the shower assembly 30 sprays clean water onto the roller mop 21 to pre-wet and dilute the stains, making it easier to scrape clean when the wet roller mop 21 reaches the squeegee 41.

[0059] The shower head assembly 30 and the squeegee 41 are respectively located on the front and rear sides of the roller mop 21, ensuring that liquid molecules have enough time to penetrate deep into the fibers of the roller mop 21 and fully interact with the dirt. This makes the subsequent squeegee 41 more effective at removing dirt than the spray-and-scrape method.

[0060] The roller mop 21 has a symmetrical plane extending vertically, along the rotation direction of the roller mop 21 ( Figure 3 In the X-direction, the plane of symmetry divides the roller mop 21 into a front side located upstream and a rear side located downstream. The shower assembly 30 is located on the front side of the roller mop 21, and the scraper 41 is located on the rear side of the roller mop 21. Optionally, the shower assembly 30 and the scraper 41 are arranged asymmetrically along the plane of symmetry of the roller mop 21. The shower assembly 30 is positioned near the upper front side of the roller mop 21, and the scraper 41 is located on the rear side, with a longer distance between the shower assembly 30 and the scraper 41 to ensure sufficient time for the liquid to wet the roller mop 21. See also... Figure 3 The shower head assembly 30 and the squeegee 41 are not only separated in front and back positions, but also differ in vertical height. The shower head assembly 30 is positioned slightly higher, while the squeegee 41 is positioned slightly lower, so as to utilize gravity to assist in scraping dirt.

[0061] The roller module 700 also includes a support cover 18. The roller brush support 10 includes a first side wall 101, a second side wall 102, and a bottom wall 103. The first side wall 101, bottom wall 103, second side wall 102, and support cover 18 are sequentially connected to form a mounting cavity 11. The bottom wall 103 is recessed into the mounting cavity 11 to form a receiving cavity 12 for accommodating the roller mop 21. The roller brush assembly 20 is housed within the receiving cavity 12. Figure 3 As shown, the shower assembly 30 is installed within the mounting cavity 11. For example, the shower assembly 30 is horizontally positioned and mounted on the bracket cover 18. See also... Figure 3 The shower head assembly 30 is installed at the connecting angle formed by the bracket cover 18 and the second side wall 102, and is inclined. A receiving groove is formed between the first side wall 101 and the bottom wall 103, and the scraper 41 and the wastewater tank 42 are both installed in the receiving groove. The receiving cavity 12 is recessed into the mounting cavity 11 and separates the shower head assembly 30 and the scraper 41. The roller brush bracket 10 is an integral structure.

[0062] like Figure 6 As shown, the roller brush assembly 20 also includes a roller brush handle 22, which is connected to one end of the roller mop 21. The roller brush handle 22 includes a handle body 220 and a roller brush button 23. The roller brush button 23 is pressable and mounted on the handle body 220, and the pressing direction of the roller brush button 23 is set at an angle to the axial direction of the roller mop 21. The roller brush bracket 10 has a first latching part 13, and the roller brush button 23 has a second latching part 231. The first latching part 13 and the second latching part 231 are engaged to prevent the roller brush assembly 20 from axially disengaging. The roller brush button 23 is used to unlock the first latching part 13 and the second latching part 231 when it is pressed.

[0063] One of the first latching part 13 and the second latching part 231 is a lock head, and the other is a lock groove; or, both the first latching part 13 and the second latching part 231 are combinations of lock heads and lock grooves, as long as the lock heads and lock grooves are set one-to-one. When it is necessary to disassemble the roller brush assembly 20, press the roller brush button 23 to unlock the first latching part 13 and the second latching part 231, then keep the roller brush button 23 pressed and pull the roller brush assembly 20 outward along the axial direction of the roller mop 21 to separate the roller brush assembly 20 from the roller brush bracket 10. When it is necessary to install the roller brush assembly 20, push the roller brush assembly 20 into the receiving cavity 12 along the axial direction of the roller mop 21, so that the first latching part 13 and the second latching part 231 engage, thereby constraining the relative position of the roller brush assembly 20 and the roller brush bracket 10 along the axial direction of the roller mop 21 and preventing the roller mop 21 from coming out of the receiving cavity 12.

[0064] In some embodiments, the pressing direction of the roller brush button 23 is perpendicular to the axial direction of the roller mop 21. The pressing direction of the roller brush button 23 refers to the direction of movement of the roller brush button 23 relative to the handle body 220. Figure 4and Figure 9 As shown, the pressing direction of the roller brush button 23 ( Figure 9 The direction of the roller brush button 23 is vertical and perpendicular to the axis of the roller mop 21. In some embodiments, the pressing direction of the roller brush button 23 is set at an acute angle to the axis of the roller mop 21. The direction in which the roller brush assembly 20 is inserted into the receiving cavity and the direction in which it is removed from the receiving cavity are both along the axis of the roller mop 21. The pressing direction of the roller brush button 23 is set at an angle to the roller mop 21, so that the pressing direction of the roller brush button 23 is not parallel to the disassembly and assembly / disassembly direction of the roller brush assembly 20, facilitating one-handed operation for pressing to unlock and pushing / pulling.

[0065] See Figure 9 The inner wall of the mounting cavity 11 has a protruding lock head as the first latching part 13, and the roller brush button 23 has a lock groove as the second latching part 231. The depth direction of the lock groove is consistent with the pressing direction of the roller brush button 23. After pressing the roller brush button 23, the roller brush button 23 moves down, causing the lock head to disengage from the lock groove, thereby unlocking the first latching part 13 and the second latching part 231.

[0066] like Figure 7 As shown, the inner side of the handle body 220 has a mounting platform 221, and the roller brush button 23 can be pressed and mounted on the mounting platform 221. Figure 4 and Figure 5 As shown, the roller brush holder 10 has a first end face 104 with a recess 105, in which the mounting platform 221 is received. The recess 105 on the first end face 104 provides accommodating space for the mounting platform 221 of the handle body 220. The inner side of the handle body 220 refers to the side of the handle body 220 facing the end of the roller mop 21. The outer side of the handle body 220 is opposite to the inner side.

[0067] like Figure 4 and Figure 7 As shown, the mounting platform 221 is located in the area where the handle body 220 extends radially outward from the roller mop 21, providing mounting space for the roller brush button 23.

[0068] The roller brush holder 10 has a snap-fit ​​hole 14, and the roller brush button 23 has an insertion part 232. A second snap-fit ​​part 231 is located on the insertion part 232. The insertion part 232 is inserted into the snap-fit ​​hole 14, causing the first snap-fit ​​part 13 located inside the roller brush holder 10 to engage with the second snap-fit ​​part 231. The snap-fit ​​hole 14 is located in the recess 105, and the insertion part 232 passes through the mounting platform 221 and is inserted into the snap-fit ​​hole 14. The snap-fit ​​positions of the first snap-fit ​​part 13 and the second snap-fit ​​part 231 are inside the mounting cavity 11, resulting in a cleaner overall appearance from the outside.

[0069] The roller brush button 23 has a cantilevered insertion part 232 protruding from the side facing the roller mop 21, and the insertion part 232 extends along the axial direction of the roller mop 21. The first latching part 13 is located inside the roller brush bracket 10. When the roller brush assembly 20 is installed, the insertion part 232 moves along the axial direction of the roller mop 21 and extends into the interior of the roller brush bracket 10 through the latching hole 14. To facilitate the alignment of the insertion part 232 with the latching hole 14, the end of the insertion part 232 has a guide surface. When the roller brush assembly 20 is pushed into the receiving cavity 12, the guide surface guides the insertion part 232 to deform and spring back after the first latching part 13 and the second latching part 231 are engaged.

[0070] See Figure 9 The lock head is located inside the roller brush bracket 10, that is, inside the mounting cavity 11. The insertion part 232 extends into the mounting cavity 11 through the snap-fit ​​hole 14, so that the lock head engages with the lock groove provided on the insertion part 232. During the process of pushing the roller brush assembly 20 into the receiving cavity 12, the lock head first abuts against the guide surface. As the insertion part 232 moves inward, the lock head pushes down the insertion part 232, causing the insertion part 232 to deform. The lock head continues to slide along the guide surface and gradually moves above the lock groove. At this time, the insertion part 232 springs back, and the lock head is locked into the lock groove, realizing the locking and fixing of the first snap-fit ​​part 13 and the second snap-fit ​​part 231.

[0071] like Figure 8 and Figure 9 As shown, the roller brush handle 22 also includes a button guide post 24, which is fixedly connected to the handle body 220. The roller brush button 23 has a mounting hole 233, and the button guide post 24 is inserted into the mounting hole 233, allowing the roller brush button 23 to move axially along the button guide post 24. The guiding function of the button guide post 24 prevents the roller brush button 23 from jamming or tilting during pressing, resulting in smoother movement of the roller brush button 23 and improved pressing feel.

[0072] In some specific embodiments, the mounting platform 221 is provided with a groove 222, the bottom of the groove 222 is provided with a slot, and the opening of the groove 222 is covered with a button fixing cover 26. The button fixing cover 26 is fixed to the handle body 220 by screws or other fasteners and covers the opening of the groove 222. One end of the button guide post 24 is inserted into the bottom of the groove 222, and the other end is inserted into the button fixing cover 26. Thus, the button guide post 24 is fixed to the handle body 220. In some other specific embodiments, the button guide post 24 is integrally formed with the handle body 220. In some other embodiments of this application, one of the roller brush button 23 and the handle body 220 is provided with a guide post, and the other is provided with a guide hole. The cooperation of the guide post and the guide hole provides guidance for the movement of the roller brush button 23. Specifically, the insertion part 232 has a protruding guide post, the handle body 220 has a guide hole, the guide post is inserted into the guide hole and can move up and down along the axial direction of the guide hole.

[0073] The roller brush handle 22 also includes a spring-loaded reset member 25, one end of which abuts against the roller brush button 23 to reset the roller brush button 23 after it has been pressed. After the user presses the button, the spring-loaded reset member 25 causes the roller brush button 23 to automatically spring back and reset, requiring no additional operation.

[0074] When the roller brush button 23 is not pressed, the elastic reset member 25 pushes against the roller brush button 23, keeping the first latching part 13 and the second latching part 231 in a tight engagement. After pressing the roller brush button 23, the elastic reset member 25 is compressed and deformed. The external force presses the roller brush button 23, overcoming the elastic force of the elastic reset member 25, and moves it downward, thus unlocking the first latching part 13 and the second latching part 231. When the roller brush button 23 is released, the elastic reset member 25 pushes the roller brush button 23 back to its original position. Optionally, the elastic reset member 25 is a telescopic spring, which is sleeved on the button guide post 24, with one end abutting against the insertion part 232 of the roller brush button 23 and the other end abutting against the bottom of the groove 222. Alternatively, the elastic reset member 25 is an elastomer such as silicone or rubber, which provides elasticity to the roller brush button 23 through its own deformation and rebound.

[0075] The roller brush button 23 has a pressing groove 234, the depth of which is aligned with the axial direction of the roller mop 21. The handle body 220 has a grip rib 223, which is used to hold and pull out the roller assembly when the user presses the roller brush button 23.

[0076] Optionally, the pressing groove 234 may be equipped with anti-slip protrusions or anti-slip textures to provide greater friction during pressing and prevent slippage. Since the depth of the pressing groove 234 is aligned with the axial direction of the roller mop 21, the cleaning robot is less likely to accidentally touch the surface when cleaning the floor, resulting in a lower probability of accidental touch compared to traditional flat pressing areas.

[0077] When disassembling the roller assembly, insert your thumb into the pressing groove 234 to press the roller brush button 23, and use your index finger and other four fingers to grip the handle 223 to hold the entire roller brush assembly 20 in your hand. Press the roller brush button 23 downwards with your thumb to unlock the first latch 13 and the second latch 231. Then, while keeping your thumb pressed down, pull the roller assembly outwards to detach the roller brush assembly 20 from the roller brush bracket 10. Thus, through the coordinated action of the pressing groove 234 and the handle 223, a reliable grip is provided, making it convenient for users to disassemble the roller brush assembly 20 with one hand and preventing the roller brush assembly 20 from slipping during disassembly, thereby improving the disassembly and assembly experience of the roller brush assembly 20.

[0078] like Figure 5 and Figure 9As shown, a detection element 19 is installed inside the roller brush holder 10, and the handle body 220 has a trigger structure 224. The trigger structure 224 is used to act on the detection element 19 when the handle body 220 is connected to the roller brush holder 10, so that the detection element 19 generates a status signal characterizing the position of the roller brush assembly 20. Figure 9 As shown, the detection element 19 is fixed inside the mounting cavity 11 for communication connection with the robot host.

[0079] In some optional embodiments, the detection element 19 is a microswitch, and the triggering structure 224 is a push rod protruding from the handle body 220. When the handle body 220 is connected to the roller brush bracket 10, the push rod presses against the microswitch, causing a change in the signal output by the microswitch, so that the robot host can confirm whether the roller brush assembly 20 is installed correctly based on the output signal of the microswitch. See also... Figure 9 The length of the push rod is greater than the length of the insertion part 232, meaning the length of the push rod extending into the roller brush bracket 10 is greater than the length of the insertion part 232 inserted into the roller brush bracket 10. This causes the micro switch to be located further inside the mounting cavity 11 than the first latching part 13. When the insertion part 232 moves downwards with the pressure applied to the roller brush button 23, the micro switch will not interfere with the movement of the insertion part 232. In some alternative embodiments, the detection element 19 is a pressure sensor. When the roller brush handle 22 is connected to the roller brush bracket 10, the trigger structure 224 presses against the pressure sensor, causing a change in the pressure value detected by the pressure sensor. The robot host determines whether the roller brush assembly 20 is properly installed based on the pressure value detected by the pressure sensor.

[0080] One of the roller brush bracket 10 and the handle body 220 is provided with a positioning post 225, and the other is provided with a positioning hole 15. The positioning post 225 and the positioning hole 15 cooperate with each other. With the cooperation of the positioning post 225 and the positioning hole 15, on the one hand, it provides guidance for the assembly of the roller brush bracket 10 and the roller brush assembly 20, and on the other hand, it forms multiple stable positioning points to achieve radial locking of the roller brush bracket 10 and the roller brush assembly 20, suppressing the shaking generated by the roller mop 21 when it rotates at high speed, and avoiding abnormal noise and potential structural damage caused by it.

[0081] For example, a positioning post 225 is provided on the roller brush holder 10, and a positioning hole 15 is provided on the handle body 220, with the positioning post 225 inserted into the positioning hole 15. See also... Figure 4 A positioning hole 15 is provided on the first end face 104 of the roller brush bracket 10, and a positioning post 225 is provided on the handle body 220. The positioning post 225 passes through the positioning hole 15 and is inserted into the mounting cavity 11. Alternatively, both the roller brush bracket 10 and the handle body 220 are provided with both positioning holes 15 and positioning posts 225, as long as the positioning posts 225 and positioning holes 15 correspond and cooperate one-to-one.

[0082] The number of positioning posts 225 may be one or more. When there are multiple positioning posts 225, they are arranged at radial intervals along the roller feeder 21. For ease of insertion, the positioning posts 225 gradually thicken from their ends to their roots. (See reference...) Figure 7 There are two positioning posts 225. The positioning posts 225 are roughly truncated pyramidal in shape, with a small cross-sectional area at the end, which makes it easy to insert into the corresponding positioning hole 15. The cross-sectional area at the root is adapted to the size of the positioning hole 15 to achieve clamping and limiting.

[0083] In some specific embodiments, one of the roller brush holder 10 and the handle body 220 is provided with an elastic buckle 226, and the other is provided with a locking hole 151, with the elastic buckle 226 engaging with the locking hole 151. Specifically, the roller brush holder 10 is provided with the elastic buckle 226, and the handle body 220 is provided with the locking hole 151; or, as... Figure 5 As shown, the first end face 104 of the roller brush holder 10 is provided with a locking hole 151, and the handle body 220 is provided with an elastic buckle 226. The elastic buckle 226 is a hook-shaped cantilever buckle. When the hook-shaped cantilever buckle passes through the locking hole 151 and extends into the mounting cavity 11, its hook hooks onto the inner side of the first end face 104. The inner side of the first end face 104 refers to the side of the first end face 104 facing into the mounting cavity 11. Of course, the roller brush holder 10 can also be provided with both the locking hole 151 and the elastic buckle 226, and the handle body 220 can be provided with the elastic buckle 226 and the locking hole 151 respectively.

[0084] The elastic buckle 226 and the locking hole 151 cooperate to achieve a detachable connection between the roller brush bracket 10 and the roller brush handle 22. The first buckle part 13 and the second buckle part 231 cooperate to achieve axial locking and fixation. The double locking enhances the stability of the axial connection. In addition, after the roller brush button 23 is pressed to unlock, the elastic buckle 226 and the locking hole 151 are still in the engaged state. At this time, pulling out the roller brush assembly 20 requires overcoming the engaging force of the elastic buckle 226 and the locking hole 151. This not only avoids axial misalignment of the roller brush assembly 20 after the first buckle part 13 and the second buckle part 231 mislock, but also provides a sense of locking when the user pulls out the roller brush assembly 20, improving the user experience.

[0085] See Figure 7The handle body 220 has positioning posts 225 with notches. Elastic buckles 226 are disposed within these notches, integrating the elastic buckles 226 with the positioning posts 225. This allows the elastic buckles 226 and positioning posts 225 to share a single hole for both locking and positioning, reducing the number of holes on the brush holder 10. It is understandable that some positioning posts 225 may have elastic buckles 226, or all positioning posts 225 may have elastic buckles 226. For example, the number of elastic buckles 226 may be the same as the number of positioning posts 225, with one elastic buckle 226 integrated on each positioning post 225. Alternatively, the number of elastic buckles 226 may be less than the number of positioning posts 225, with some positioning posts 225 having elastic buckles 226 while others do not. The elastic buckles 226 are made of plastic and utilize their own plastic deformation to engage with the locking holes 151. After the first latch 13 and the second latch 231 are unlocked, the elastic latch 226 and the latch hole 151 are still in the latched state. The user pulls the roller brush assembly 20 outward along the axis of the roller mop 21 to disengage the elastic latch 226 from the latch hole 151, thereby disassembling the roller brush bracket 10 and the roller brush handle 22.

[0086] The roller brush handle 22 rotates in conjunction with the roller mop 21. For example... Figure 18 As shown, the drive unit 50 and the roller mop 21 are connected via a connector 51. During the rotation of the roller mop 21 driven by the drive unit 50, the roller brush bracket 10 and the roller brush handle 22 remain stationary. Optionally, the ends of the roller brush handle 22 and the roller mop 21 are connected by bearings. The inner ring of the bearing is fixedly connected to the roller mop 21, and the outer ring of the bearing is rotatably engaged with the roller mop 21.

[0087] In some alternative embodiments, the roller brush handle 22 is detachably connected to the roller mop 21. For example, the roller brush handle 22 is connected to the roller mop 21 by a snap-fit ​​mechanism. Alternatively, the roller brush handle 22 is connected to the roller mop 21 by a swivel joint. When the roller mop 21 wears out and needs to be replaced, the user only needs to replace the roller mop 21, while the fully functional roller brush handle 22 can be reused, reducing the amount of consumables and the user's subsequent operating costs.

[0088] like Figure 10 As shown, the shower head assembly 30 is mounted on the roller brush bracket 10. Figure 11 and Figure 12As shown, the shower assembly 30 has spray holes 32 and anti-clogging supports 31. The spray holes 32 spray water onto the roller mop 21, and the anti-clogging supports 31 are interference-fitted with the roller mop 21. Along the rotation direction of the roller mop 21 when cleaning the floor, the anti-clogging supports 31 are located upstream of the spray holes 32. That is, the same area of ​​the roller mop 21 passes through the anti-clogging supports 31 first, and then through the spray holes 32. When the roller mop 21 rotates to clean the floor, the anti-clogging supports 31 can prevent impurities on the roller mop 21 from entering the spray holes 32, thus preventing impurities from affecting the normal water output of the spray holes 32.

[0089] like Figure 12 As shown, the anti-clogging rib 31 is a reinforcing rib or scraper protruding from the shower head assembly 30. The cavity wall of the receiving cavity 12 has multiple through holes, and the anti-clogging rib 31 is correspondingly positioned with each through hole. The anti-clogging rib 31 extends into the receiving cavity 12 through the corresponding through hole and is press-fitted with the roller mop 21. Optionally, the end face of the anti-clogging rib 31 is an arc-shaped concave surface 331, parallel to the outer wall of the roller mop 21; or, the end face of the anti-clogging rib 31 is a flat surface. As long as the anti-clogging rib 31 is press-fitted with the roller mop 21, it is acceptable.

[0090] The water spray holes 32 are arranged in a straight line or curve along the axial direction of the roller mop 21. Anti-clogging supports 31 are correspondingly arranged to the water spray holes 32. Optionally, only some of the water spray holes 32 are equipped with anti-clogging supports 31. Alternatively, all water spray holes 32 are equipped with anti-clogging supports 31. For example, the water spray holes 32 and anti-clogging supports 31 are arranged in a one-to-one correspondence. Or, two or three water spray holes 32 share one anti-clogging support 31. When the roller mop 21 cleans the floor, it rotates counterclockwise. The anti-clogging supports 31 are located upstream of the water spray holes 32 in the counterclockwise direction, thus allowing the anti-clogging supports 31 to pre-clean away dirt on the roller mop 21, reducing the risk of dirt being carried to the water spray holes 32 and causing blockage.

[0091] In some alternative embodiments, there is a gap between the spray nozzles 32 and the roller mop 21. For example, the spray nozzles 32 are located on the side of the shower assembly 30 facing the roller mop 21, and the axis of the spray nozzles 32 is along the radial direction of the roller mop 21. When the roller mop 21 rotates to clean the floor, the spray nozzles 32 spray water directly towards the roller mop 21. If there is no gap between the spray nozzles 32 and the roller mop 21, the water sprayed from the spray nozzles 32 will be directly absorbed by the roller mop 21, and the multiple spray nozzles 32 can only form multiple spray points on the roller mop 21, failing to spray water over a large area on the surface of the roller mop 21. Therefore, the shower assembly 30 provided in this application has a gap between the spray nozzles 32 and the roller mop 21, so that the water flow sprayed from the spray nozzles 32 can cover a larger area of ​​the roller mop 21.

[0092] In some alternative embodiments, such as Figure 11 and Figure 12 As shown, the shower assembly 30 has multiple bosses 33 on the side facing the roller mop 21, and spray holes 32 are provided on the circumferential side of the bosses 33. Figure 13 and Figure 14 As shown, the anti-clogging rib 31 is arranged around the outside of the corresponding boss 33 and the height of the anti-clogging rib 31 is higher than the height of the boss 33. The water spray hole 32 is located on the circumferential side of the boss 33 and water is discharged from the side. Compared with the water spray hole 32 that sprays water directly, it can reduce the risk of dirt on the roller mop 21 clogging the water spray hole 32.

[0093] The boss 33 enhances the structural strength and rigidity of the shower assembly 30 around the spray holes 32, preventing cracking or deformation of the shower assembly 30 under long-term use and vibration, thus improving durability. Each boss 33 may have one, two, three, or more spray holes 32. The boss 33 may have an interference fit with the roller mop 21, or there may be a gap between the boss 33 and the roller mop 21. This application does not specifically limit this, as long as the height of the boss 33 is lower than the anti-clogging rib 31, and the anti-clogging rib 31 has an interference fit with the roller mop 21. The outer surface of the boss 33 is smooth to prevent it from scratching the roller mop 21 when in contact with it.

[0094] During the rotation of the roller mop 21, even if some dirt bypasses the anti-clogging rib 31 and enters the gap between the anti-clogging rib 31 and the boss 33, it still needs to accumulate before it can completely block the water spray hole 32 located on the side of the boss 33. Thus, the anti-clogging rib 31 and the side water spray hole 32 provide a double anti-clogging measure, which slows down the speed at which the water spray hole 32 is blocked.

[0095] like Figure 12 As shown, a water flow channel 34 is formed between the boss 33 and the anti-clogging rib 31, allowing at least a portion of the water sprayed from the spray holes 32 to flow into the water flow channel 34. The gap between the boss 33 and the anti-clogging rib 31 forms the water flow channel 34, allowing all or part of the water sprayed from the spray holes 32 to flow into the water flow channel 34. The water flow is then spread along the wall of the anti-clogging rib 31 onto the roller mop 21. Compared to traditional spray holes 32, the water flow channel 34 transforms the point-like water spray into a surface application, allowing the water to contact the roller mop 21 in a wider water film state, thus enabling faster and more even wetting of the roller mop 21. Furthermore, the water flow is buffered and dispersed within the water flow channel 34, rather than directly impacting the high-speed rotating roller mop 21, thus reducing water splashing and allowing more water to be effectively absorbed by the roller mop 21.

[0096] like Figure 12 As shown, the circumferential side of the boss 33 has at least one concave surface 331, and the concave surface 331 is provided with a water spray hole 32.

[0097] The number of concave surfaces 331 can be one, two, three, or four, etc. One or more water spray holes 32 can be provided on the same boss 33. For example, the boss 33 has one water spray hole 32 and a concave surface 331. The water spray hole 32 is located on the concave surface 331, which increases the distance between the opening of the water spray hole 32 and the wall of the anti-clogging support 31, thus providing more space for dirt bypassing the anti-clogging support 31 and slowing down the clogging speed of the water spray hole 32. Furthermore, the concave surface 331 can conceal the water spray hole 32, and the roller mop 21 only contacts the edge of the concave surface 331, making it less likely to directly scrape the opening of the water spray hole 32, reducing the risk of clogging. The boss 33 can have multiple water spray holes 32 and multiple concave surfaces 331, with the water spray holes 32 corresponding to the concave surfaces 331 one-to-one, or only some of the water spray holes 32 can be located on the concave surfaces 331. For example, the boss 33 has two water spray holes 32 and two concave surfaces 331, with one water spray hole 32 on each concave surface 331. Alternatively, the boss 33 may have two water spray holes 32 and one concave surface 331, with one water spray hole 32 located on the concave surface 331 and the other water spray hole 32 located in the non-concave surface 331 area of ​​the boss 33.

[0098] like Figure 15 As shown, the anti-clogging rib 31 covers at least a portion of the water spray hole 32 on the boss 33. It should be noted that when only one water spray hole 32 is provided on the boss 33, the anti-clogging rib 31 covers part or all of that water spray hole 32. When multiple water spray holes 32 are provided on the boss 33, the anti-clogging rib 31 covers part or all of the entire structure formed by the multiple water spray holes 32. For example, if the boss 33 has two water spray holes 32, referred to as the first water spray hole 32 and the second water spray hole 32, with the water outlet direction of the first water spray hole 32 facing the direction of the roller mop 21 and the water outlet direction of the second water spray hole 32 along the axial direction of the roller mop 21, the anti-clogging rib 31 completely blocks the first water spray hole 32 and covers part or all of the second water spray hole 32.

[0099] The water outlet direction of the spray nozzle 32 is inclined relative to the radial direction of the roller mop 21. That is, the water outlet direction of the spray nozzle 32 is not perpendicular to the roller mop 21, but rather sprays obliquely onto the roller mop 21. Compared to vertical spraying, the obliquely sprayed water flow generates a velocity component parallel to the surface of the roller mop 21 when it impacts the surface of the roller mop 21, which better peels off and washes away particulate dirt adhering to the fibers of the roller mop 21. At the same time, the oblique spraying also increases the contact path length and contact time between the water flow and the roller mop 21, resulting in a better wetting effect compared to the direct rebound after vertical spraying.

[0100] In some specific embodiments, at least some of the spray holes 32 have their water outlet direction aligned with the axial direction of the roller mop 21. For example, all the spray holes 32 in the shower assembly 30 may have their water outlet direction aligned with the axial direction of the roller mop 21, or only some of the spray holes 32 may have their water outlet direction aligned with the axial direction of the roller mop 21. Because the water outlet direction of the spray holes 32 is consistent with the axial direction of the roller mop 21, when the roller mop 21 rotates to clean the floor, the orientation of the spray holes 32 is completely offset from the direction in which the roller mop 21 comes from. Dirt carried by the roller mop 21 is less likely to be drawn into the openings of the side spray holes 32.

[0101] In some specific embodiments, the boss 33 and the anti-clogging rib 31 are arranged in a one-to-one correspondence. The boss 33 has a concave surface 331, and the water spray hole 32 is set on the concave surface 331. The water outlet direction of the water spray hole 32 is consistent with the axial direction of the roller mop 21. Thus, the anti-clogging rib 31 pre-scrapes off some dirt on the rotation path of the roller mop 21, forming a first layer of protection. Then, by using the water outlet direction of the water spray hole 32 to be consistent with the axial direction of the roller mop 21, the opening of the water spray hole 32 is offset from the direction of the roller mop 21, preventing dirt from turning into the water spray hole 32, forming a second layer of protection. The water spray hole 32 is set on the concave surface 331 in the circumferential side of the boss 33. The edge of the concave surface 331 blocks the opening of the water spray hole 32, forming a third layer of protection, thereby forming multiple layers of physical isolation and reducing the possibility of the water spray hole 32 becoming clogged. For example, as Figure 12 As shown, the boss 33 has two concave surfaces 331, both of which are recessed into the interior of the boss 33 and are arranged opposite to each other. Each concave surface 331 is provided with a water spray hole 32, and the water outlet direction of the water spray hole 32 is consistent with the axial direction of the roller mop 21.

[0102] The anti-clogging rib 31 has an opening 311, the angles formed by the two sides of the opening 311 and the surrounding center of the anti-clogging rib 31 are less than 180°. The opening 311 is located on the rear side of the anti-clogging rib 31. When the roller mop 21 rotates, the opening 311 is located on the back side of the rotation path, which does not affect the cleaning effect of the anti-clogging rib 31. The opening 311 facilitates the cleaning of dirt accumulated in the water flow channel. In some specific embodiments, such as Figure 12 and Figure 15 As shown, the anti-clogging rib 31 is arc-shaped, with the boss 33 located at its center. Optionally, the anti-clogging rib 31 is symmetrical along a radial section of the roller fabric 21, with two concave surfaces 331 located on opposite sides of this radial section. Each concave surface 331 has a water spray hole 32, and the boss 33 has a total of two water spray holes 32. The angle formed between the two sides of the opening 311 and the surrounding center of the anti-clogging rib 31 is less than 180°, so that the anti-clogging rib 31, while having an opening 311, covers as many water spray holes 32 as possible, reducing the risk of clogging of the water spray holes 32.

[0103] like Figure 3 As shown, the water spray nozzle 32 is located on the front side of the roller mop 21. After the roller mop 21 cleans the floor, the water spray nozzle 32 sprays water onto the cleaned mop. To prevent the water sprayed from the nozzle 32 from flowing onto the floor, the water spray nozzle 32 can optionally be located at the upper front side, so that even if the water flows downwards, it will still follow the surface of the roller mop 21.

[0104] In some specific embodiments, such as Figure 3 As shown, the shower assembly 30 is installed in the mounting cavity 11 and is inclined at the connection angle formed by the bracket cover 18 and the second side wall 102.

[0105] like Figure 14 and Figure 15 As shown, the shower assembly 30 includes a first housing 301 and a second housing 302. The first housing 301 and the second housing 302 are sealed together to form a flat and elongated delivery channel 303. The delivery channel 303 is connected to the clean water tank through a water inlet pipe. A boss 33 and an anti-clogging rib 31 are both provided on the outer surface of the second housing 302. Each spray hole 32 is connected to the delivery channel 303.

[0106] Optional, such as Figure 3 As shown, the shower assembly 30 is inclined within the mounting cavity 11. Specifically, the mounting surface of the shower assembly 30 forms an acute angle with the horizontal plane. For example, the angle between the mounting surface of the shower assembly 30 and the horizontal plane is 45°, which balances space utilization with the required spray coverage. The inner wall of the mounting cavity 11 is provided with a slot, in which the shower assembly 30 is fitted and secured in a corner by the pressure of the bracket cover 18 and the second side wall 102.

[0107] By tilting the shower assembly 30, the direction and coverage of the water jet can be controlled more precisely. This allows the spray nozzles 32 to face the surface of the roller mop 21 more naturally, eliminating the need for additional angle compensation at the spray nozzles 32 and simplifying the design and manufacturing of the shower assembly 30 itself. Furthermore, compared to horizontal or vertical installations, a larger shower assembly 30 can be placed within the same installation space. If shower assemblies of the same size are used, the tilted installation provides more space for other structural components compared to horizontal or vertical installations, maximizing the use of dead space within the mounting cavity 11 and resulting in a more compact overall structure.

[0108] like Figure 16 As shown, the scraper 41 has a sludge collection groove 414, a squeegee edge 411, and a water-retaining edge 412. Both the water-retaining edge 412 and the squeegee edge 411 are located at the opening of the sludge collection groove 414. The squeegee edge 411 is interference-fitted with the roller mop 21 to scrape dirt from the roller mop 21 into the sludge collection groove 414. The height of the water-retaining edge 412 is higher than the height of the squeegee edge 411.

[0109] When the surface of the roller mop 21 carrying sewage and stains passes over the scraper 41, the sewage is scraped off by the scraper edge 411 and falls into the sewage collection trough 414 of the scraper 41, where the sewage is collected. Because the height of the water-blocking edge 412 is higher than that of the scraper edge 411, even if the cleaning robot moves quickly or scrapes off a large amount of sewage, the scraped sewage can be blocked by the water-blocking edge 412 and will not splash or overflow.

[0110] See Figure 16 The bottom of the sludge collection tank 414 is provided with at least one drain hole 415. The number of drain holes 415 can be one or more. When there is only one drain hole 415, it is located in the middle of the sludge collection tank 414 or near one end of the sludge collection tank 414. Optionally, the drain hole 415 is a strip-shaped hole extending along the length of the sludge collection tank 414, with the length of the strip-shaped hole being greater than half the length of the sludge collection tank 414, thereby enabling rapid discharge of wastewater from the sludge collection tank 414. When there are multiple drain holes 415, they are spaced apart along the length of the sludge collection tank 414.

[0111] By providing a drain hole 415 in the sludge collection tank 414, the sewage collected in the sludge collection tank 414 can be quickly discharged into the sewage tank 42, preventing sewage from overflowing after the sludge collection tank 414 is full. In addition, providing a drain hole 415 ensures that the scraper blade 41 will not stop working when the sludge collection tank 414 is full, thereby ensuring that the scraper blade 41 can operate continuously.

[0112] In some embodiments, a guide block protrudes from the outer wall of the scraper 41, and a drain hole 415 passes through the guide block. In the cleaning robot, the outer side of the bottom wall 103 of the scraper 41 abuts against the opening of the sewage tank 42. Due to the assembly gap between the scraper 41 and the sewage tank 42, splashing water droplets may leak out from the gap. To address this, a guide block is provided on the scraper 41 and inserted into the sewage tank 42. The protruding guide block extends the outlet end of the drain hole 415 towards the bottom of the sewage tank 42, shortening the free fall distance of the sewage and sealing the gap between the scraper 41 and the sewage tank 42. After the water flows out of the drain hole 415, it is constrained by the inner wall of the guide block until it enters the sewage tank 42 before being released, thus suppressing water splashing. In addition, the width of the guide block is adapted to the width of the sewage tank 42. The guide block can play a role in physical positioning and connection, ensuring that the relative position of the scraper 41 and the sewage tank 42 is accurate. In some other embodiments, see [reference needed]. Figure 3 The sludge collection tank 414 has a certain depth, and the tank wall of the sludge collection tank 414 is inserted into the sewage tank 42. The tank wall of the sludge collection tank 414 covers the connection gap between the sewage tank 42 and the outer wall of the scraper 41.

[0113] Optionally, there may be one or more guide blocks. For example, there may be one drain hole 415 and one guide block, with the drain hole 415 passing through the guide block. Alternatively, there may be multiple drain holes 415 and one or more guide blocks. When there is only one guide block, it covers multiple drain holes 415. When there are multiple guide blocks, each guide block covers at least one drain hole 415. For example, guide blocks and drain holes 415 may be arranged in a one-to-one correspondence. Alternatively, two adjacent drain holes 415 may form a group, with one guide block covering one group of drain holes 415.

[0114] The bottom of the sludge collection trough 414 has an inclined guide surface 413, which slopes downward from the end of the scraper 41 along its length toward the drain hole 415. When only one drain hole 415 is provided, the guide surface 413 is provided on both sides of the sludge collection trough 414, and the bottom of the sludge collection trough 414 is V-shaped, with the drain hole 415 located at the lowest point of the V-shape. When multiple drain holes 415 are provided, the two ends of the integral formed by the multiple drain holes 415 are provided with guide surfaces 413, making the bottom of the sludge collection trough 414 V-shaped. Alternatively, the two ends of the integral formed by the multiple drain holes 415 and between adjacent drain holes 415 are provided with guide surfaces 413, making the bottom of the sludge collection trough 414 continuously W-shaped, with each drain hole 415 located at the lowest point. The guide surface 413 slopes downward from the end of the scraper 41 along its length toward the drain hole 415, which can prevent sewage from accumulating at the edge of the scraper 41 and leaking out from the edge. Under the action of gravity, the sewage collected in the collection tank 414 automatically flows along the guide surface 413 toward the lower drain hole 415, and is guided to the drain hole 415 opened at the bottom, so that the sewage falls vertically into the sewage tank 42 below through the drain hole 415.

[0115] The diameter of the drain hole 415 is not less than half the width of the bottom of the sludge collection tank 414. When the scraper 41 is working, the instantaneous volume of water scraped off may be large. The drainage speed of the sludge collection tank 414 needs to be greater than or equal to the collection speed of the sewage to prevent the water level in the sludge collection tank 414 from rising rapidly and overflowing. Therefore, the smaller the diameter of the drain hole 415, the weaker the drainage capacity. In this application, the diameter of the drain hole 415 is not less than half the width of the bottom of the sludge collection tank 414, which can form a high-flow-rate drainage channel, ensuring that its drainage capacity is sufficient to cope with the peak water volume under most operating conditions and effectively preventing overflow caused by poor drainage. Furthermore, the sewage scraped off by the scraper 41 often contains solid dirt such as hair, dust, and flocculent matter. A large-diameter drain hole 415 is less likely to be blocked by these dirt particles, ensuring the long-term reliable and unobstructed drainage path.

[0116] The water-blocking edge 412 is continuously installed along both sides of the sludge collection trough 414 and the side of the sludge collection trough 414 away from the scraper edge 411. Sludge enters the sludge collection trough 414 from the scraper edge 411 side. Without the water-blocking edge 412, the water flow may overflow to the sides and rear of the sludge collection trough 414 due to inertia, sloshing, or accumulation. The rear of the sludge collection trough 414 refers to the side of the sludge collection trough 414 away from the scraper edge 411. The side of the sludge collection trough 414 with the scraper edge 411 is used to receive the sludge scraped off by the scraper edge 411. The continuous installation of the water-blocking edge 412 along both sides of the sludge collection trough 414 and the side of the sludge collection trough 414 away from the scraper edge 411 can construct a three-sided surrounding physical enclosure structure, blocking the sides and rear of the sludge collection trough 414 and preventing sludge from overflowing from the sides and rear of the sludge collection trough 414.

[0117] In some embodiments, the scraper 41 is fixed to the robot body or the clean water tank. In yet other embodiments, such as Figure 2 As shown, the scraper blade 41 is fixed to the roller brush bracket 10. Specifically, the scraper blade 41 is fastened to the roller brush bracket 10 by multiple screws. The wastewater tank 42 is installed on the roller brush bracket 10 and located below the scraper blade 41, used to collect the dirt scraped off by the scraper blade 41. Specifically, the wastewater tank 42 is installed on the roller brush bracket 10 by a snap-fit ​​mechanism. See reference. Figure 3 and Figure 17 The roller brush support 10 has a baffle 16 and a leak-proof rib 161 disposed on the baffle 16. The baffle 16 abuts against the end of the water-blocking edge 412, and the side wall of the leak-proof rib 161 is tightly fitted with the inner side wall of the water-blocking edge 412. Thus, a double-stop structure is formed between the roller brush support 10 and the scraper 41. If sewage in the sludge collection tank 414 wants to cross the water-blocking edge 412, it must first cross the gap between the side wall of the leak-proof rib 161 and the inner wall of the water-blocking edge 412. This creates a physical barrier that sewage that may overflow the water-blocking edge 412 must climb upwards to cross, extending and complicating the leakage path, and ultimately preventing sewage from overflowing from the assembly gap between the roller brush support 10 and the scraper 41.

[0118] Optional, such as Figure 2 and Figure 3 As shown, a filter screen 43 is installed inside the sewage tank 42. The sewage tank 42 is connected to the sewage container via a sewage pipe, and a water pump is installed on the sewage pipe. The filter screen 43 blocks particulate matter in the sewage, preventing it from entering the water pump and affecting its normal operation, and also preventing the sewage pipe from becoming clogged. For easy cleaning, the sewage tank 42 is detachably mounted on the roller brush bracket 10. When the filter screen 43 needs cleaning, the sewage tank 42 is removed from the roller brush bracket 10, cleaned, and then reinstalled on the roller brush bracket 10.

[0119] In some optional embodiments, the scraper 41 is detachably connected to the roller brush holder 10, wherein the roller brush assembly 20 and the scraper 41 are installed and removed in the same direction. For example, the scraper 41 is snapped into the roller brush holder 10. Over time, the scraper edge 411 will wear down, reducing its effectiveness in removing stains. In this case, the scraper 41 is removed from the roller brush holder 10 and replaced with a new one. The scraper 41 is removed in the same direction as the roller brush assembly 20, thus allowing for a simpler installation and removal point on the same end of the roller module 700, simplifying its appearance.

[0120] In some embodiments, the roller module 700 further includes a clean water tank and a wastewater tank. The clean water tank is connected to the shower head via a clean water pipe, and the wastewater tank is connected to the wastewater trough 42 via a wastewater pipe. The wastewater trough 42 and the shower head assembly 30 are respectively located on the rear and front sides of the roller mop 21, and correspondingly, the wastewater pipe and the clean water pipe are respectively located on the rear and front sides of the roller mop 21. Since the front side of the roller mop 21 has limited space, while the rear side has more space, both the clean water tank and the wastewater tank are located on the rear side of the roller mop 21.

[0121] See Figure 18 , Figure 19 and Figure 20 The cavity wall of the receiving chamber 12 is constructed with comb teeth 17, which are interference-fitted with the roller mop 21. The shower assembly 30 is mounted on the roller brush bracket 10. The shower assembly 30 has spray holes 32, with a gap between the spray holes 32 and the roller mop 21. The spray holes 32 are used to spray water onto the roller mop 21 after cleaning the floor. Along the rotation direction of the roller mop 21 during the cleaning process, the comb teeth 17 are located upstream of the spray holes 32.

[0122] like Figure 18 As shown, a drive unit 50 is installed inside the accommodating cavity 12, and a connector 51 is mounted on the drive shaft of the drive unit 50. After the roller mop 21 is inserted axially into the accommodating cavity 12, the connector 51 is inserted and fixed inside the roller mop 21. Optionally, the drive unit 50 is a motor. When the cleaning robot is working, the drive unit 50 drives the roller mop 21 to rotate counterclockwise, and the rotating roller mop 21 passes through the comb teeth 17 and the water spray holes 32 in sequence.

[0123] Due to the interference fit between the comb teeth 17 and the roller mop 21, when the roller mop 21 rotates, its fibers are forcibly combed and squeezed by the comb teeth 17. Thus, the comb teeth 17 can scrape away and intercept hair, fibers, and other debris entangled on the roller mop 21. The tips of the comb teeth 17 form an interference fit with the fiber area of ​​the roller mop 21 in the radial direction. That is, the tips of the comb teeth 17 penetrate into the space occupied by the fibers in the natural state of the roller mop 21. A gap exists between the water spray hole 32 and the outer edge contour of the fibers in the natural state of the roller mop 21, ensuring that the water spray hole 32 does not physically contact the high-speed rotating roller mop 21, avoiding wear and clogging, while simultaneously spraying water evenly onto the fibers of the roller mop 21.

[0124] See Figure 20 Along the direction of rotation of the roller mop 21 when cleaning the floor ( Figure 20 In the X direction, the comb teeth 17 are positioned upstream of the water spray holes 32 to ensure that the roller mop 21 is cleaned and loosened by the comb teeth 17 before being wetted. This prevents the debris from being pressed deeper into the fibers after being wetted, and the comb teeth 17 can separate the fibers on the roller mop 21 that have become stuck and collapsed due to water and pressure, so that the roller mop 21 can be restored to a fluffy state, increasing the effective cleaning diameter and softness of the roller mop 21, thereby improving cleaning efficiency.

[0125] See Figure 19 The comb teeth 17 have a first wall surface 171 facing the rotation direction of the roller mop 21 and a second wall surface 172 facing away from the rotation direction of the roller mop 21. The inclination of the first wall surface 171 is greater than that of the second wall surface 172, resulting in an asymmetrical tooth shape in the cross-section of the comb teeth 17. Specifically, along the rotation direction of the roller mop 21, the first wall surface 171 contacts the roller mop 21 first compared to the second wall surface 172. The first wall surface 171 is an arc surface or slope with a larger inclination, that is, the slope of the first wall surface 171 is steeper, which can effectively scrape off and intercept the combed hair and debris. The second wall surface 172 has a smaller inclination and a gentler slope, which can smoothly carry debris into the spaces between the comb teeth 17, protecting the fibers and reducing the load on the drive unit 50. This comb tooth 17 shape can effectively clean the debris carried by the roller mop 21 while avoiding excessive damage to the fibers of the roller mop 21.

[0126] The multiple comb teeth 17 include a first tooth body and a second tooth body, the tooth height of the first tooth body is higher than the tooth height of the second tooth body, and the first tooth body and the second tooth body are staggered. It can be understood that one or more second tooth bodies can be set between two adjacent first tooth bodies.

[0127] The nap of the roller mop 21 has a certain thickness, and debris and tangles not only occur on the surface but also penetrate deep into the middle layer and even the roots of the nap. The first tooth, with its larger tooth height, can reach deeper into the nap, effectively combing through severely clumped and collapsed nap clumps caused by pressure and moisture, and scraping away stubborn debris buried deep within. The second tooth, with its smaller tooth height, primarily works on the surface and middle layers of the nap, scraping away hair and dust adhering to the surface, and further smoothing the nap after the initial combing by the first tooth.

[0128] By using the staggered arrangement of the first and second teeth, it is ensured that any area on the surface of the roller mop 21 will be combed by the high and low teeth when it rotates, avoiding any missed areas in the depth direction of the roller mop 21 due to the uniformity of tooth height, and ensuring the uniformity of processing throughout the depth of the roller mop 21.

[0129] Optionally, the tips of the comb teeth 17 penetrate 1mm-3mm into the inner edge of the pile of the roller mop 21 in its natural state. That is, the interference of the comb teeth 17 is 1mm-3mm. For example, the tips of the comb teeth 17 penetrate 1mm, 3mm, 1.5mm, or 2mm into the inner edge of the pile of the roller mop 21 in its natural state, or any value between 1mm and 3mm.

[0130] If the interference fit of the comb teeth 17 is too small, the contact force between the comb teeth 17 and the fibers on the roller mop 21 will be insufficient. For compacted fibers and tightly tangled hair, it will not generate enough combing and scraping force, affecting the combing effect. If the interference fit of the comb teeth 17 is too large, excessive friction and resistance will be generated, which will not only accelerate the wear of the fibers on the roller mop 21 and shorten its service life, but also increase the load on the drive component 50, potentially leading to a decrease in the speed of the drive component 50, increased power consumption, or even stalling and burnout. The interference fit of the comb teeth 17 is 1mm-3mm, which ensures both cleaning and loosening effects while keeping wear and energy consumption within an acceptable and reasonable range.

[0131] Optionally, the gap between the water spray hole 32 and the outer edge contour of the pile of the roller mop 21 in its natural state is 2mm-5mm. For example, the gap between the water spray hole 32 and the outer edge contour of the pile of the roller mop 21 in its natural state is any value between 2mm and 5mm, such as 2mm, 5mm, 2.5mm, or 3mm.

[0132] The roller mop 21 exhibits dynamic balance and slight vibration during high-speed rotation. If the gap is too small, lint can easily sweep against the spray nozzles 32, potentially scratching or clogging them, leading to poor water flow or malfunction. The water jet energy from the spray nozzles 32 is limited. If the gap is too large, the water flow will be excessively atomized and diffused due to air resistance before reaching the mop, resulting in inaccurate spraying, uneven wetting, and some water mist may escape into the machine, posing a potential risk. Setting the gap between 2mm and 5mm ensures that the water flow can be accurately and evenly sprayed onto the target area of ​​the roller mop 21 for efficient wetting, while also providing sufficient safety distance to avoid the risk of clogging due to physical contact.

[0133] Multiple comb teeth 17 are arranged in a straight line or a wavy line along the axial direction of the roller mop 21. In some embodiments, all comb teeth 17 are arranged in a straight line, which is simple to manufacture. In other embodiments, the comb teeth 17 are arranged in a wavy line. When a long hair is wrapped around the axial direction of the roller mop 21, the comb teeth 17 arranged in a straight line may be difficult to remove effectively. However, the comb teeth 17 arranged in a wavy line provide a lateral guiding force to the hair wrapped around the axial direction as the roller mop 21 rotates, making it easier for the hair to be hooked and scraped off by the comb teeth 17 located at the crests or troughs of the waves. It can be seen that the comb teeth 17 arranged in a wavy line can enhance the capture ability of axially wrapped debris. In addition, for the same point on the roller mop 21, the force pattern is exactly the same every time it passes through the comb teeth 17 arranged in a straight line. However, when passing through the comb teeth 17 arranged in a wavy line, the force point and angle are slightly different, which helps to distribute the wear more evenly on different parts of the hair, avoid the formation of deep wear marks in some areas, and thus extend the overall service life of the mop.

[0134] Multiple comb teeth 17 are arranged in multiple rows along the rotation path of the roller mop 21. The tooth shape of the comb teeth 17 in different rows is different, which decomposes the complex combing task into different rows of comb teeth 17, optimizes the task of each row of comb teeth 17, and forms a progressive multi-level processing method, which further improves the overall processing efficiency and the final effect.

[0135] Optionally, two rows of comb teeth 17 are arranged along the rotation path of the roller mop 21. The first row of comb teeth 17 has a larger tooth pitch, thicker teeth, and sharper scraping angle, responsible for breaking up severely clumped lint and scraping off large or tightly tangled debris. The second row of comb teeth 17 has a smaller tooth pitch, thinner teeth, and a more rounded shape. The results of the first row of comb teeth 17 are further refined by combing, subdividing the lint, removing small particles, and making the entire roller mop 21 more fluffy.

[0136] This application also provides a cleaning robot, see embodiments thereof. Figure 21 It includes a base 710 and a roller module 700 as described above, with the roller brush bracket 10 connected to the base 710.

[0137] Specifically, the roller module 700 is capable of vertical movement on the base 710. When the roller module 700 rises relative to the base 710, the roller mop 21 moves away from the ground; when the roller module 700 descends relative to the base 710, the roller mop 21 moves closer to the ground to perform cleaning operations. Optionally, the roller module 700 can also move horizontally on the base 710 to expand the cleaning range of the roller mop 21.

[0138] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
