[0088] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0089] This embodiment provides a cleaning device, as shown in FIG1 . The cleaning device includes a body 100 and a cleaning head 200 disposed at the bottom of the body 100. The body 100 includes a body assembly 11, a functional assembly 12, and a handle 13. The handle 13 is disposed at the top of the body assembly 11, the cleaning head 200 is disposed at the bottom of the body assembly 11, and the functional assembly 12 is disposed on the body assembly 11. The functional assembly 12 includes a clean water tank and a dirty water tank. The user grips the handle 13 to move the body 100, thereby pushing the cleaning head 200 to move across the surface to be cleaned to achieve the cleaning purpose.

[0090] The cleaning head 200 includes a housing assembly and at least one cleaning roller. The cleaning roller is rotatably disposed in the housing assembly, and both ends of the cleaning roller are rotatably connected to the housing assembly so that the cleaning roller can rotate relative to the housing assembly.

[0091] When cleaning a surface, long foreign objects like hair or thread can become entangled in the cleaning roller, requiring regular cleaning. Existing cleaning rollers are typically cleaned with a cutter or removed and then cleaned with auxiliary accessories. This not only results in poor cleaning effectiveness, is inconvenient, and inefficient, but also easily stains the user's hands, severely impacting the user experience.

[0092] To solve the above problem, in this embodiment, a mounting hole is provided on the housing assembly, and at least one of all cleaning rollers can be installed or removed from the housing assembly via the mounting hole. Specifically, the axis of the mounting hole is parallel to the axis of the cleaning roller. Usually, the axis of the cleaning roller is along the length direction of the cleaning head 200. Therefore, the mounting hole can be provided on the side wall of the housing assembly in the length direction. Depending on the different positions and different types of cleaning rollers, the mounting hole can be selected at a suitable location. In one possible implementation, as shown in FIG2 , the mounting hole 232 'is provided on the side wall of the housing assembly; in other possible implementations, the mounting hole can also be provided on other components of the housing assembly.

[0093] In one possible implementation, the shell assembly includes a first side wall and a second side wall arranged opposite to each other, the mounting hole is arranged on the second side wall, the end of the cleaning roller away from the mounting hole is detachably connected to the first side wall, and the end of the cleaning roller close to the mounting hole passes through the mounting hole and is detachably connected to the second side wall.

[0094] As shown in Figure 3, the cleaning head 200 also includes a hair cleaner 25. The hair cleaner 25 is arranged at the mounting hole of the housing assembly and is capable of contacting the circumferential outer wall of the cleaning roller during the process of pulling the cleaning roller out through the mounting hole along the pulling-out direction, so as to achieve cleaning of the cleaning roller on the basis of disassembling the cleaning roller. The pulling-out direction is: when the cleaning roller is installed on the housing assembly, it points from the end of the cleaning roller away from the mounting hole to the end of the cleaning roller close to the mounting hole, and this direction is also parallel to the axis of the cleaning roller. The hair cleaner 25 includes a plurality of cleaning teeth 252, which are arranged at intervals along the circumference of the mounting hole. The plurality of cleaning teeth 252 are arranged at intervals around the circumference of the cleaning roller. The cleaning teeth 252 are used to contact the circumferential outer wall of the cleaning roller during the process of pulling the cleaning roller out through the mounting hole to achieve cleaning.

[0095] Specifically, the cleaning roller can be a soft rubber roller brush, a bristle roller brush, a sponge roller brush, a soft velvet roller brush or a velvet roller brush. The surface of the soft rubber roller brush is covered with a soft rubber layer, and the outer peripheral surface of the soft rubber layer can be formed with multiple rows or single rows of rubber convex columns; the surface of the bristle roller brush is provided with a number of bristle bundles, and there are various ways to plant the bristle bundles, which can be arranged parallel to the axis of the roller brush or in a spiral shape; the surface of the sponge roller brush is covered with a sponge layer, which can be a PVA strong water-absorbing sponge, and cleaning is achieved through its water absorption properties; the surface of the soft velvet roller brush or the velvet roller brush is provided with a soft velvet layer or velvet layer for cleaning. In addition, the cleaning roller can be a component that directly contacts the ground, or it can be other rolling bodies provided on the cleaning head (described in detail below). Similarly, the hair cleaner 25 can be provided corresponding to the above-mentioned different types of cleaning rollers.

[0096] In this embodiment, as shown in Figure 3, the hair remover 25 further includes an annular body 251, which is connected to the housing assembly and can be sleeved onto the outside of the cleaning roller. One end of the cleaning teeth 252 is connected to the inner side of the annular body 251, and the other end of the cleaning teeth 252 extends obliquely toward the end of the cleaning roller away from the mounting hole. The cleaning teeth 252 are arranged at an angle so that the ends of the cleaning teeth 252 can more easily pick up long foreign objects such as hair or thread on the cleaning roller when withdrawn, thereby ensuring that the long foreign objects such as hair or thread are entangled with the cleaning teeth 252, thereby improving the cleaning effect on the cleaning roller.

[0097] To further facilitate the cleaning teeth 252 in picking up long foreign objects such as hair or thread, as shown in Figures 3 and 4, the cross-sectional area of ​​the cleaning teeth 252 gradually decreases as it moves away from the annular body 251, so that the end of the cleaning tooth 252 that contacts the hair is a pointed end with a smaller cross-section. This facilitates the cleaning tooth 252 to extend between the cleaning roller and the long foreign objects such as hair or thread, thereby preventing the long foreign objects such as hair or thread from being pulled out of the housing assembly along with the cleaning roller. The cross-sectional area of ​​the cleaning tooth 252 is perpendicular to the length of the cleaning tooth 252. As shown in Figure 4, the line connecting the center of the root of the cleaning tooth 252 to the center of the tooth tip is defined as the length of the cleaning tooth 252, and this line intersects the axis b of the annular body 251. The length direction of the cleaning tooth 252 is the X direction, and the cross-sectional area a is perpendicular to the X direction. The cross-sectional area of ​​the cleaning tooth 252 obtained by cutting the cleaning tooth 252 by cross-sectional area a is the cross-sectional area. It should be noted that the length direction of each cleaning tooth 252 is different. The X direction in Figure 4 is the length direction corresponding to the cut cleaning tooth 252.

[0098] In this embodiment, the cleaning tooth 252 has a trapezoidal longitudinal cross-section. One base of the trapezoid is connected to the annular body 251, while the other base forms the end surface of the free end of the cleaning tooth 252. Both sides of the trapezoid, including the waist, extend obliquely toward the end of the cleaning roller away from the mounting hole. A longitudinal cross-section is defined as a section parallel to the length of the cleaning tooth 252 and passing through the axis b of the annular body 251. This longitudinal cross-section is the cross-section of the cleaning tooth 252 shown in Figure 4.

[0099] Specifically, the cleaning tooth 252 includes a tooth portion 2521, which includes a first tooth flank, a second tooth flank, a third tooth flank, a fourth tooth flank, and a tooth top surface. The first tooth flank and the second tooth flank are arranged axially along the annular body 251, and the third tooth flank and the fourth tooth flank are arranged circumferentially along the annular body 251. One end of the first tooth flank, the second tooth flank, the third tooth flank, and the fourth tooth flank are connected to the annular body 251, and the other end is connected to the tooth top surface, so that the cleaning tooth 252 is roughly a quadrangular prism structure, and the tooth top surface forms the free end of the tooth portion 2521. In order to make the end size of the cleaning tooth 252 smaller, the first tooth flank and the second tooth flank both extend obliquely toward the end of the cleaning roller away from the mounting hole, and the distance between the third tooth flank and the fourth tooth flank gradually decreases along the radial direction of the mounting hole toward the center of the mounting hole.

[0100] In other embodiments, the cleaning teeth 252 may be in other shapes, for example, the cross section of the cleaning teeth 252 may be circular, oval, or irregular.

[0101] To better capture long foreign objects such as hair or thread, in one possible implementation, the cleaning teeth 252 include a tooth portion 2521 and a rib 2522 arranged at an angle. One end of the tooth portion 2521 is connected to the annular body 251, and the other end is connected to the rib 2522. The tooth portion 2521 extends from the inner side of the annular body 251 toward the center of the mounting hole and is angled toward the end of the cleaning roller away from the mounting hole. The rib 2522 extends from the tooth portion toward the end of the cleaning roller away from the mounting hole. The provision of the tooth portion 2521 reduces the distance between the end of the cleaning tooth 252 and the surface of the cleaning roller, making it easier for the cleaning tooth 252 to reach and contact long foreign objects such as hair or thread. The angle between the side of the rib 2522 facing the center of the mounting hole and the surface of the cleaning roller is smaller than the angle between the side of the tooth portion 2521 facing the center of the mounting hole and the surface of the cleaning roller, making it easier for the rib 2522 to penetrate between the long foreign objects such as hair or thread and the cleaning roller, thereby improving the cleaning effect.

[0102] Optionally, as shown in FIG5 , the extension direction of the rib 2522 may be substantially parallel to the axis of the cleaning roller, so as to intercept long foreign objects such as hair or thread as the cleaning roller is drawn out.

[0103] In this embodiment, the diameter of the circular area enclosed by the free ends of the plurality of cleaning teeth 252 is slightly smaller than the outer diameter of the cleaning roller, so that the cleaning teeth 252 have a certain interference fit with the cleaning roller, which is beneficial to improving the cleaning effect of foreign matter. For the sponge roller brush, soft velvet roller brush or flannel roller brush mentioned above, the interference fit between the cleaning teeth 252 and the cleaning roller should be set relatively small to avoid increasing the extraction resistance of the cleaning roller; for the soft rubber roller brush and planted bristle roller brush mentioned above, the interference fit between the cleaning teeth 252 and the cleaning roller can be set relatively large to improve the cleaning effect of long foreign matter such as hair or thread wrapped around the bristles; and the soft rubber or bristle bundles have a certain flexibility and can be deformed to pass through the circular area.

[0104] In one possible embodiment, the area where the cleaning teeth 252 contact the cleaning roller has at least one edge, which can apply shear force to the foreign matter when the cleaning teeth 252 pick up the entangled long foreign matter such as hair or thread, so as to cut off the long foreign matter such as hair or thread, thereby improving the cleaning effect of the foreign matter.

[0105] As shown in FIG6 , in this embodiment, the housing assembly includes a housing 21 and a trash box 23 disposed in the housing 21. The cleaning roller includes at least two, specifically: at least one rotating body 22 and at least one cleaning roller brush 24. In this embodiment, the rotating body 22 is selected as a sponge roller brush, and the cleaning roller brush 24 is selected as a bristle roller brush. Of course, other suitable types of roller brushes can also be selected according to actual needs. The rotating body 22 is rotatably disposed on the bottom surface of the housing 21, and is used to contact the surface to be cleaned (such as the ground) to clean dirt; the trash box 23 is detachably disposed in the housing 21, and an entrance is provided on the side of the trash box 23 facing the rotating body 22; the cleaning roller brush 24 is rotatably disposed at the entrance of the trash box 23, and can abut against the rotating body 22, and is used to clean dirt on the surface to be cleaned (such as the rotating body 22).

[0106] The following description uses the example of a cleaning roller comprising a rotating body 22 and a cleaning brush 24. The axes of the cleaning brush 24 and the rotating body 22 are parallel, and the axial dimensions of the cleaning brush 24 and the rotating body 22 can be roughly equal to improve the cleaning effect of the cleaning brush 24 on the rotating body 22. As shown in Figure 7, a mounting hole 232 and a hair remover 25 are provided at positions corresponding to the cleaning brush 24. When the cleaning brush 24 is withdrawn through the mounting hole 232, the circumferential outer wall of the cleaning brush 24 contacts the cleaning teeth 252 on the hair remover 25, thereby cleaning the cleaning brush 24.

[0107] The axis of the cleaning roller brush 24 is parallel to the axis of the rotating body 22, and both are arranged along the length direction of the cleaning head 200. When the cleaning head 200 moves on the surface to be cleaned (such as the ground), the rotating body 22 actively rotates counterclockwise in the direction of the arrow shown in Figure 6. Hair, debris, and other garbage on the surface to be cleaned can adhere to the rotating body 22 and move with the rotating body 22. Because the cleaning roller brush 24 abuts the rotating body 22, the cleaning roller brush 24 can rotate with the rotating body 22. In other words, the cleaning roller brush 24 is not provided with a driving device, but is driven by the rotating body 22. It should be noted that: the rotating body 22 and the cleaning roller brush 24 have an interference fit, and the cleaning roller brush 24 is driven to rotate by the rotating body 22. However, the contact point between the rotating body 22 and the cleaning roller brush 24 produces relative motion, and the two have different rotation speeds, so that the cleaning roller brush 24 can clean the dirt on the rotating body 22. The cleaning roller brush 24 cleans the surface of the rotating body 22, allowing impurities such as hair and debris adhering to the surface of the rotating body 22 to be peeled off from the rotating body 22 and enter the trash box 23 through the entrance of the trash box 23, thereby achieving garbage collection. Of course, there can also be multiple rotating bodies 22 or cleaning roller brushes 24, with one cleaning roller brush 24 corresponding to one rotating body 22, one cleaning roller brush 24 corresponding to multiple rotating bodies 22, multiple cleaning roller brushes 24 corresponding to one rotating body 22, or multiple cleaning roller brushes 24 corresponding to multiple rotating bodies 22, all of which can be configured according to actual needs. In this embodiment, the cleaning roller brush 24 is used to clean the rotating body 22, which can prevent the residual hair, debris, and other particles on the rotating body 22 from affecting the cleaning effect of the surface to be cleaned.

[0108] In this embodiment, as shown in Figures 7, 8, and 9, the trash can 23 is detachably connected to the housing 21. Trash can 23 is provided with a mounting hole 232 located on a side wall thereof. The cleaning roller brush 24 can be inserted into or removed from the trash can 23 through the mounting hole 232. A hair remover 25 is disposed within the mounting hole 232 of the trash can 23 and at the second end of the cleaning roller brush 24 for cleaning the cleaning roller brush 24.

[0109] In this embodiment, the cleaning roller brush 24 and the hair cleaner 25 can be removed from the housing 21 along with the trash can 23. The cleaning roller brush 24 can then be pulled out of the trash can 23 through the mounting hole 232. During the removal process, the cleaning roller brush 24 passes through the hair cleaner 25. The cleaning teeth 252 on the hair cleaner 25 can hook onto hair entangled with the cleaning roller brush 24, causing the hair to break away from the cleaning roller brush 24 and accumulate on the cleaning teeth 252 or fall into the trash can 23, thereby cleaning the cleaning roller brush 24. This method does not require auxiliary tools such as a cutting knife, is easy to operate, and has a good cleaning effect. The user can remove the cleaning roller brush 24 by contacting the end of the cleaning roller brush 24 without getting their hands dirty, thus improving the user experience.

[0110] Specifically, the cleaning roller brush 24 is positioned at the entrance, and correspondingly, the mounting hole 232 is located near the entrance. This arrangement not only facilitates the cleaning roller brush 24 in cleaning the rotating body 22, but also allows the trash swept by the cleaning roller brush 24 to fall directly into the trash bin 23 through the entrance, improving trash collection efficiency. A hair remover 25 is positioned at the second end of the cleaning roller brush 24, ensuring that all axial locations of the cleaning roller brush 24 pass through the hair remover 25 during extraction, thereby enhancing the cleaning efficiency of the cleaning roller brush 24.

[0111] To facilitate the installation and removal of the trash can 23, as shown in Figures 2, 6, and 7, the housing 21 includes a bottom housing 212 and a top cover 211. The top of the bottom housing 212 is provided with an opening, and the top cover 211 is removably connected to the bottom housing 212 to cover the opening. The bottom housing 212 is provided with a mounting slot that is compatible with the trash can 23. The trash can 23 is located within the mounting slot, making it easy to remove and place the trash can 23. The top cover 211 is provided with a hand grip 2111 to facilitate the installation and removal of the top cover 211.

[0112] To facilitate the removal or insertion of the cleaning roller brush 24 from or into the mounting hole 232, the first end of the cleaning roller brush 24 is detachably and rotatably connected to the inner wall of the trash box 23. The second end of the cleaning roller brush 24 passes through the hair remover 25 and the mounting hole 232, then detachably and rotatably connects to the outer wall of the trash box 23. This arrangement allows one end of the cleaning roller brush 24 to extend outside the trash box 23, making it easier for the user to grasp and remove or install the cleaning roller brush 24. At the same time, it ensures that the cleaning roller brush 24 can rotate relative to the trash box 23, thereby ensuring that the cleaning function of the rotating body 22 is achieved.

[0113] In this embodiment, as shown in Figures 8, 9, and 10, the annular body 251 is connected to the trash can 23 and is sleeved outside the cleaning roller brush 24. The cleaning teeth 252 extend obliquely toward the first end of the cleaning roller brush 24. The ends of the cleaning teeth 252 that come into contact with the hair are pointed with a smaller cross-section. This allows the cleaning teeth 252 to easily extend between the cleaning roller brush 24 and the hair, thereby preventing the hair from being pulled out of the trash can 23 along with the cleaning roller brush 24.

[0114] The tooth portion 2521 of the cleaning tooth 252 helps reduce the distance between the end of the cleaning tooth 252 and the surface of the cleaning roller brush 24, making it easier for the cleaning tooth 252 to extend into the hair bundle of the implanted hair and remove long foreign matter such as hair or thread from the hair bundle of the cleaning roller brush 24. The angle between the side of the rib 2522 facing the center of the mounting hole 232 and the surface of the cleaning roller brush 24 is smaller than the angle between the side of the tooth portion 2521 facing the center of the mounting hole 232 and the surface of the cleaning roller brush 24, making it easier for the rib 2522 to be inserted between the hair and the cleaning roller brush 24, thereby improving the cleaning effect. Optionally, the extension direction of the rib 2522 can be roughly parallel to the axis of the cleaning roller brush 24 so that it can intercept long foreign matter such as hair or thread as the cleaning roller brush 24 is withdrawn.

[0115] In order to facilitate the replacement of the hair cleaner 25, the hair cleaner 25 is detachably mounted on the outer wall of the trash box 23, and the cleaning teeth 252 extend into the mounting hole 232 to clean the cleaning roller brush 24 and facilitate the cleaned hair to fall into the trash box 23.

[0116] Specifically, the annular body 251 includes a sleeve 2511, which is inserted into the mounting hole 232. The cleaning teeth 252 are connected to the inner wall of the sleeve 2511. The outer wall of the sleeve 2511 is connected to a first flange 2512, which is detachably connected to the trash can 23. The provision of the first flange 2512 increases the contact area between the annular body 251 and the trash can 23, thereby improving the fixing effect of the annular body 251 and the trash can 23. In this embodiment, the first flange 2512 can be fixed to the trash can 23 by fasteners, wherein the fasteners are screws. In other embodiments, the first flange 2512 can be fixed to the trash can 23 by snapping, thereby facilitating replacement of the hair cleaner 25.

[0117] To further enhance the securement of the hair cleaner 25 to the trash can 23, as shown in Figures 3 and 9, a second flange 2513 is connected to the outer wall of the sleeve 2511. The trash can 23 is provided with a socket 231, into which the second flange 2513 is inserted. The cooperation between the second flange 2513 and the socket 231 enables the hair cleaner 25 to be positioned with respect to the trash can 23, facilitates the fastener connection between the first flange 2512 and the trash can 23, and enhances the securement.

[0118] In this embodiment, the first flange 2512 extends downward from the sleeve 2511, and the second flange 2513 extends upward from the sleeve 2511. The cooperation between the first flange 2512 and the second flange 2513 can improve the relative position accuracy of the hair cleaner 25 and the garbage box 23, ensure the coaxiality of the sleeve 2511 and the cleaning roller brush 24, avoid the sleeve 2511 from interfering with the disassembly and assembly of the cleaning roller brush 24, and ensure the cleaning effect of the hair cleaner 25 on the cleaning roller brush 24.

[0119] To ensure that the cleaning roller brush 24 can rotate relative to the trash bin 23 and facilitate the removal and assembly of the cleaning roller brush 24, as shown in Figures 8-11, the cleaning head 200 also includes a movable end cover 261. The movable end cover 261 is detachably mounted on the outer wall of the trash bin 23 and covers the mounting hole 232. The second end of the cleaning roller brush 24 is rotatably connected to the movable end cover 261. When the user needs to remove the cleaning roller brush 24, the movable end cover 261 can be removed to drive the cleaning roller brush 24 away from the trash bin 23, thereby pulling the cleaning roller brush 24 out of the mounting hole 232. The movable end cover 261 can also cover the mounting hole 232 when the cleaning roller brush 24 is installed in the trash bin 23, preventing garbage in the trash bin 23 from spilling out through the mounting hole 232, improving the user experience and ensuring aesthetics.

[0120] To facilitate assembly and disassembly of the movable end cover 261 and the trash box 23, a first suction member is provided on the outer wall of the trash box 23, and a second suction member is provided on the side of the movable end cover 261 facing the trash box 23. The first suction member and the second suction member are attracted to each other to secure the movable end cover 261 and the trash box 23. The attraction between the first and second suction members secures the movable end cover 261 and the trash box 23, making assembly and disassembly easy and having a simple structure.

[0121] To improve the relative positioning accuracy of the first and second suction members, a first positioning groove is provided on the outer wall of the trash box 23, into which the first suction member is fixed. A second positioning groove 2612 is provided on the side of the movable end cover 261 facing the trash box 23, into which the second suction member is fixed. The first positioning groove secures the first suction member, while the second positioning groove 2612 secures the second suction member, ensuring that the first and second suction members are aligned, thereby ensuring a secure suction effect.

[0122] In some embodiments, the first positioning groove may be provided only on the trash box 23 , or the second positioning groove 2612 may be provided only on the movable end cover 261 , both of which can improve the fixing effect of the first adsorption member and the second adsorption member.

[0123] Furthermore, as shown in Figures 3 and 12 , the hair cleaner 25 also includes a third flange 2514. The third flange 2514 is located outside the trash can 23. An annular flange 25141 is provided on the side of the third flange 2514 facing the trash can 23. The third flange 2514 is used to block the first positioning groove, and the annular flange 25141 is inserted into the first positioning groove to enhance the blocking effect of the third flange 2514 on the first positioning groove. The first and second suction members are located on either side of the third flange 2514. On the one hand, the third flange 2514 blocks the first positioning groove to protect the first suction member; on the other hand, the clamping action of the first and second suction members further secures the hair cleaner 25, ensuring the stability of the position of the hair cleaner 25.

[0124] To prevent the movable end cap 261 from rotating with the cleaning roller brush 24, as shown in Figures 11 and 12 , a positioning notch 2611 is provided on the movable end cap 261, and a positioning protrusion 253 is provided on the hair cleaner 25. The positioning protrusion 253 is inserted into the positioning notch 2611. The cooperation between the positioning protrusion 253 and the positioning notch 2611 prevents the movable end cap 261 from rotating with the cleaning roller brush 24. In this embodiment, the positioning notch 2611 is provided on the circumferential edge of the movable end cap 261, and the positioning protrusion 253 is formed by extending the side wall of the sleeve 2511 away from the cleaning teeth 252, thereby simplifying the structure of the hair cleaner 25.

[0125] In other embodiments, a positioning protrusion 253 is provided on the movable end cover 261 , and correspondingly, a positioning notch 2611 is provided on the hair cleaner 25 , which can also prevent the movable end cover 261 from rotating with the cleaning roller brush 24 .

[0126] The cleaning head 200 also includes a fixed end cap 262, which is fixedly mounted within the trash bin 23. The first end of the cleaning roller brush 24 is rotatably inserted into the fixed end cap 262. Specifically, the fixed end cap 262 is mounted on the side wall of the trash bin 23 opposite the side wall where the mounting hole 232 is located. The fixed end cap 262 is provided with a first rotation hole, into which one end of the cleaning roller brush 24 is inserted and rotatably engages. This arrangement is structurally simple and facilitates assembly and disassembly of the cleaning roller brush 24 and the fixed end cap 262.

[0127] Specifically, as shown in Figure 13, the cleaning roller brush 24 includes a roller 241, a first rotating shaft 242, and a second rotating shaft 243. The first rotating shaft 242 is fixed to one end of the roller 241 and rotatably inserts into a first rotating hole in the fixed end cap 262. The second rotating shaft 243 is fixed to the other end of the roller 241 and rotatably connected to the movable end cap 261. The first rotating shaft 242 and the second rotating shaft 243 can be fixedly connected to the roller 241 via a threaded pair. The end surface of the roller 241 is spaced apart from the inner wall of the trash bin 23. The movable end cap 261 is provided with a second rotating hole, through which the second rotating shaft 243 passes. A clamp is mounted on the end of the second rotating shaft 243 that extends out of the second rotating hole. The clamp tightens the second rotating shaft 243 and abuts the side of the movable end cap 261 facing away from the trash bin 23, thereby fixing the axial position of the second rotating shaft 243 and the movable end cap 261.

[0128] To better clean hair from the cleaning roller brush 24, the surface of the roller 241 of the cleaning roller brush 24 is provided with at least two ridges 247. The ridges 247 extend axially along the roller 241 and are spaced apart circumferentially along the roller 241. The provision of at least two ridges 247 supports hair wrapped around the cleaning roller brush 24, preventing the hair from directly contacting the surface of the roller 241. This facilitates the insertion of the cleaning teeth 252 between the hair and the roller 241, thereby lifting the hair and improving the cleaning effect of the cleaning roller brush 24.

[0129] Furthermore, the end of the cleaning tooth 252 is lower than the top surface height of the ridge 247. At the same time, there is a gap between the end of the cleaning tooth 252 and the surface of the roller 241 other than the ridge 247. This arrangement makes it easier for the cleaning tooth 252 to extend between the hair and the roller 241 and reduces the friction between the cleaning tooth 252 and the surface of the roller 241.

[0130] Optionally, the height of the ridges 247 is 0.3 mm to 1 mm, such as 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, or 0.9 mm. The gap between the ends of the cleaning teeth 252 and the surface of the roller 241 other than the ridges 247 is 0.1 mm to 0.5 mm, such as 0.2 mm, 0.3 mm, or 0.4 mm. However, this gap should be smaller than the height of the ridges 246, ensuring that the free ends of the cleaning teeth 252 can extend into the recessed areas formed between adjacent ridges 247 to facilitate the removal of entangled hair. When the ridges 247 and the gap are within this height range, the hair is effectively supported, preventing direct contact between the hair and the roller 241 and facilitating the insertion of the ends of the cleaning teeth 252 between the hair and the surface of the roller 241. Furthermore, the cleaning teeth 252 can also contact the surface of the cleaning roller 24 when the cleaning roller 24 is withdrawn laterally, thereby reducing resistance to the withdrawal of the cleaning roller 24.

[0131] In this embodiment, the cleaning roller brush 24 is a bristle-planted roller brush, i.e., bristles are planted on the roller 241. Specifically, the cleaning roller brush 24 includes a first bristle assembly 244, which is disposed on the outer circumference of the roller 241. The first bristle assembly 244 includes a plurality of clusters of first bristles, which can contact the rotating body 22 to clean impurities such as hair and particulate matter thereon.

[0132] In some embodiments, multiple clusters of first bristles may be arranged in a straight line along the axis of the roller 241 , or multiple clusters of first bristles may be arranged in an S-shape, or multiple clusters of first bristles may be arranged in a spiral around the axis of the roller 241 , all of which may have the effect of cleaning the rotating body 22 .

[0133] Furthermore, the distribution of multiple clusters of first bristles in an S-shaped or spiral arrangement allows the first brush assembly 244 to form multiple point contacts with the rotating body 22. Compared with the line contact between the bristles and the rotating body when arranged in a straight line, the friction between the cleaning roller brush 24 and the rotating body 22 can be reduced, ensuring that the cleaning roller brush 24 cleans debris on the rotating body 22 with reasonable contact force and contact points.

[0134] In this embodiment, there is one first bristle assembly 244. In other embodiments, there may be at least two first bristle assemblies 244, with at least two first bristle assemblies 244 spaced apart along the circumference of the roller 241, forming multiple spirally arranged first bristles, so that hairs are more easily wrapped around the cleaning roller brush 24, thereby improving the cleaning effect on the rotating body 22.

[0135] In this embodiment, the cleaning roller brush 24 further includes a second bristle assembly 245, which includes a plurality of tufts of second bristles spaced apart along the circumference of the roller 241. The second bristle assembly 245 is disposed at one end of the roller 241 proximal to the hair remover 25. The provision of the second bristle assembly 245 not only increases the friction between the cleaning roller brush 24 and the rotating body 22 as needed, but also prevents hair from contacting the second rotating shaft 243, thereby preventing hair from becoming entangled in the second rotating shaft 243 or the cleaning teeth 252, leading to ineffective or obstructed rotation of the second end of the cleaning roller brush 24 and the movable end cap 261.

[0136] In addition, when the cleaning roller brush 24 is pulled outward and the first end is about to be separated from the hair cleaner 25, a large amount of hair has accumulated on the second end of the cleaning roller brush 24 and the end of the cleaning teeth 252, so that the resistance between the cleaning roller brush 24 and the hair cleaner 25 is large. Therefore, the second brush assembly 245 is not provided at the end of the roller 241 away from the hair cleaner 25, which can avoid the user from struggling when pulling out the cleaning roller brush 24, thereby improving the user experience.

[0137] In some embodiments, the cleaning roller brush 24 may be provided with second bristle assemblies 245 at both ends to increase the friction between the cleaning roller brush 24 and the rotating body 22 according to actual needs.

[0138] To prevent hair from moving toward the first end of the cleaning roller brush 24 and entering the first rotating hole, the cleaning roller brush 24 also includes a third bristle assembly 246. The third bristle assembly 246 is disposed at the first end of the roller brush and includes multiple tufts of third bristles. The tops of the third bristles extend obliquely toward the side wall of the trash can 23 connected to the first end of the cleaning roller brush 24. In other words, the third bristles extend obliquely upward from the surface of the roller 241 and toward the fixed end cap 262 to prevent hair from entering the first rotating hole, thereby ensuring the rotational coordination between the first rotating shaft 242 and the first rotating hole.

[0139] In some possible implementations, the cleaning roller brush 24 can be set on a shell component outside the trash box 23. Accordingly, the hair cleaner 25 and the movable end cover 261 are set following the cleaning roller brush 24 to ensure that the cleaning roller brush 24 passes through the hair cleaner 25 at all axial positions during the extraction process, so as to improve the cleaning of the surface of the cleaning roller brush 24.

[0140] To achieve a better cleaning effect, this embodiment employs a method in which the first bristles are arranged in a spiral pattern around the axis of the roller 241. However, the bristles may be implanted on the ridge 247, and the height of the ridge 247 is relatively steep, that is, the curvature at the junction of the ridge 247 and the non-ridge varies greatly, which can easily cause the ridge 247 to break. To prevent the ridge 247 from breaking, the prior art often provides a notch on the ridge 247 to avoid the location of the bristle implantation, or does not implant bristles at the ridge 247 to avoid the ridge 247 from breaking. In addition, the high height of the ridge 247 will result in a large resistance of the hair cleaner to the cleaning roller 24 when the cleaning roller 24 is pulled out, making it difficult for the user to operate the cleaning roller 24, and the cleaning effect of the straight-line bristle implantation is poor.

[0141] To solve the above problems, the outer circumferential surface of the roller 241 includes an inner concave arc surface and an outer convex arc surface that are alternately arranged along the circumference, and a ridge 247 is formed on the outer convex arc surface. By alternating the inner concave arc surface and the outer convex arc surface, the cross-sectional profile of the roller 241 can be made into a curve with different curvatures, and the curvature of the curve is alternately arranged in positive and negative directions, so that the cross-sectional shape of the roller 241 is petal-shaped. In some embodiments, the absolute values ​​of the curvatures of the inner concave arc surface and the outer convex arc surface can be equal or unequal. This structure of the roller 241 can not only form the ridge 247, but also make the ridge 247 have a relatively gentle height, so that even if bristles are implanted on the ridge 247, the ridge 247 will not break. In this way, the position and method of the bristle implantation are not restricted, and there is no need to avoid the ridge, and the distribution of the bristle implantation on the circumferential surface is more uniform. The smaller height of the ridge 247 can also reduce the resistance encountered when the cleaning roller brush 24 is pulled out, making the disassembly and assembly of the cleaning roller brush 24 more labor-saving and improving the user experience.

[0142] It can be understood that in the above embodiment, the cleaning head 200 includes a rotating body 22 and a cleaning roller brush 24, which is one possible implementation method. In some other possible implementation methods, the cleaning head 200 may include at least one rotating body 22 and at least one cleaning roller brush 24. The number of rotating bodies 22 and cleaning roller brushes 24 can be selected and combined according to actual needs to improve the cleaning effect.

[0143] Of course, in some other possible implementations, the cleaning head 200 may not be provided with a cleaning roller brush 24, and may only include at least one rotating body 22 to clean the surface to be cleaned (such as the ground); or it may not be provided with a rotating body 22, and may only include at least one cleaning roller brush 24 to clean other surfaces to be cleaned inside the cleaning head 200. These settings can be made according to actual needs.

[0144] Regardless of the number of the rotating body 22 and the cleaning roller brush 24, a corresponding hair cleaner 25 can be provided according to actual needs and structure to ensure that the rotating body 22 and / or the cleaning roller brush 24 pass through the cleaning teeth 252 of the hair cleaner 25 at all axial positions during the extraction process, thereby improving the cleaning of the surface of the rotating body 22 and / or the cleaning roller brush 24.

[0145] In order to improve the cleaning effect of the rotating body 22, as shown in Figure 14, the cleaning head 200 also includes a sewage squeezing strip 215, which is arranged below the upper cover 211 of the casing 21 and abuts against the top of the rotating body 22; the casing 21 also includes a sewage chamber 213 and a clean water chamber 214, the sewage chamber 213 is arranged on the side of the sewage squeezing strip 215 close to the garbage box 23, and the clean water chamber 214 is arranged on the side of the sewage squeezing strip 215 away from the garbage box 23, and the casing 21 is provided with a sewage inlet connected to the sewage chamber 213 and a clean water outlet connected to the clean water chamber 214. When the cleaning head 200 is in operation, the rotor 22 rotates counterclockwise as shown in Figure 11. The rotor 22 carries dirt and passes through the cleaning roller brush 24. The cleaning roller brush 24 sweeps impurities such as hair and particulate matter on the rotor 22 into the trash box 23. The rotor 22 continues to rotate, and the sewage carried by the rotor 22 passes through the sewage squeezing strip 215. The sewage squeezing strip 215 can abut against the rotor 22 to squeeze the sewage adsorbed on the rotor 22, causing the sewage to overflow. The overflowing sewage enters the sewage chamber 213 through the sewage inlet for sewage collection. After squeezing out the sewage, the rotor 22 passes through the clean water chamber 214. The clean water in the clean water chamber 214 contacts the rotor 22 through the clean water outlet to rinse the rotor 22. During the rotation of the rotor 22, the rotor 22 repeatedly passes through the cleaning roller brush 24, the sewage chamber 213, the sewage squeezing strip 215, and the clean water chamber 214 to achieve a cleaning effect.

[0146] In this embodiment, the cleaning roller brush 24 is used to clean the solid debris such as hair, particulate matter, etc. on the rotating body 22. The cooperation of the sewage squeezing strip 215, the sewage chamber 213 and the clean water chamber 214 can flush the rotating body 22 and clean the liquid dirt on the rotating body 22 to improve the cleaning effect of the rotating body 22.

[0147] In this embodiment, the housing 21 also includes a clean water box and a dirty water box, both of which are located on the bottom surface of the upper cover 211. A clean water chamber 214 is formed within the clean water box, and a dirty water chamber 213 is formed within the dirty water box. To reduce the number of components in the cleaning head 200, a protrusion is provided on the bottom of the end of the dirty water box near the clean water box. This protrusion forms a dirty water squeeze strip 215, integrating the functionality of the dirty water squeeze strip 215 into the dirty water box, simplifying the structure.

[0148] To facilitate the supply of clean water and the removal of wastewater, the housing 21 is provided with a sewage channel and a clean water channel. One end of the sewage channel connects to the sewage chamber 213 and the other end is connected to the sewage tank. One end of the clean water channel connects to the clean water chamber 214 and the other end is connected to the clean water tank. The clean water tank on the housing 100 supplies clean water to the clean water chamber 214 for flushing the rotor 22. The wastewater in the sewage chamber 213 is pumped into the sewage tank in the housing 100 to ensure a flushing effect on the rotor 22 and collect the wastewater. It is understood that the sewage tank can also use an air pump to generate negative pressure to draw wastewater from the sewage chamber 213.
