[0028] Embodiments of the present application are described below in detail with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and cannot be understood as a limitation of the present application.

[0029] Referring to FIG. 1, a rolling brush assembly 1000 of an embodiment of the present application includes a roller body 100 and cleaning units, the number of which can be one or more groups, and the multiple groups of cleaning units are arranged along the circumferential direction of the roller body 100. The cleaning units include brush conditions 200, scraping conditions 300, and protruding structures 400. The brush conditions 200 and the scraping conditions 300 are used to contact and clean the object to be cleaned, and the protruding structures 400 are not in contact with the object to be cleaned, and there is a gap between the protruding structures 400 and the object to be cleaned. The brush conditions 200 are connected to the outer circumferential wall of the roller body 100 and arranged along the radial direction of the roller body 100. The scraping conditions 300 are connected to the outer circumferential wall of the roller body 100 and arranged along the radial direction of the roller body 100. It should be noted that the brush conditions 200 include a plurality of brush strip parts, the brush strip parts are arranged along the radial direction of the roller body 100, and the plurality of brush strip parts are arranged along the axial direction of the roller body 100. The brush strip parts can be thin strip structures or thick strip structures, and the brush strip parts can be arranged as a brush or a rubber strip. The scraping conditions 300 can be understood as leather conditions or rubber conditions, and the scraping conditions 300 extend along the axial direction of the roller body 100. The scraping conditions 300 can scrape dust and garbage on the surface of the object to be cleaned, and the hair 500 is difficult to entangle on the scraping conditions 300, and the scraping conditions 300 can support the hair. The cleaning granularity of the brush conditions 200 is higher than that of the scraping conditions 300, and the use of the brush conditions 200 and the scraping conditions 300 can enhance the cleaning effect. The brush conditions 200 and the scraping conditions 300 can be connected to the roller body 100 by means of glue, buckling, fasteners, etc.

[0030] Referring to FIG. 1, the protruding structure 400 is connected to the roller body 100, the protruding structure 400 is arranged along the radial direction of the roller body 100, and the protruding structure 400 is also arranged along the axial direction of the roller body 100. Along the radial direction of the roller body 100, the maximum height of the brush condition 200 to the axis of the roller body 100 is greater than the maximum height of the protruding structure 400 to the axis of the roller body 100, and the maximum height of the scraping condition 300 to the axis of the roller body 100 is also greater than the maximum height of the protruding structure 400 to the axis of the roller body 100. It can also be understood that, along the radial direction of the roller body 100, the maximum protruding height of the brush condition 200 is higher than the maximum protruding height of the protruding structure 400, and the maximum protruding height of the scraping condition 300 is higher than the maximum protruding height of the protruding structure 400, so that the brush condition 200 and the scraping condition 300 can be in contact with the object to be cleaned, and the protruding structure 400 is prevented from hindering the cleaning of the brush condition 200 and the scraping condition 300. In the circumferential direction of the roller body 100, the protruding structure 400 is located on one side of the brush condition 200, and the scraping condition 300 is located on the other side of the brush condition 200. The scraping condition 300 and the protruding structure 400 can support the long hair 500 and other long debris on both sides of the brush condition 200, which is equivalent to stretching or opening the long hair 500, so that the long hair 500 is not easy to entangle at the root of the brush condition 200. With the rotation of the roller body 100, the centrifugal force is generated, and the long hair 500 can be gradually separated from the brush condition 200, which can alleviate the problem of entanglement of the long hair 500 on the brush condition 200. The long hair 500 entangled on the roller brush assembly 1000 is less, and the long hair 500 is supported by the scraping condition 300 and the protruding structure 400, so that there is a large gap between the long hair 500 and the roller body 100. When cleaning the long hair 500, the user can more easily find the point of application, which is convenient for the user to clean the long hair 500 and improves the user experience.

[0031] In some embodiments, the protruding structure 400 and the roller body 100 can be two separate part structures, and the protruding structure 400 can be connected and installed together with the roller body 100 through a mounting structure, for example, through glue sticking, buckle connection, fastener connection, welding and the like. In some embodiments, the protruding structure 400 and the roller body 100 can be an integral structure, which is directly manufactured by an integral molding process to form the roller body 100 and the protruding structure 400, without the need for installation operation.

[0032] Referring to FIGS. 1 and 2, in some embodiments, the number of cleaning units can be three groups, and adjacent two groups of cleaning units can be arranged at an interval of 120 degrees from each other, which is more balanced in position distribution, ensures better cleaning effect, and also ensures that the long hair 500 can be more evenly supported.

[0033] It can be understood that in some embodiments, the rolling brush assembly 1000 is driven by a driving motor to rotate automatically, the rolling brush assembly 1000 drives the brush condition 200 and the scraping condition 300 to rotate together, and the brush condition 200 and the scraping condition 300 clean the object to be cleaned. The rotating direction of the rolling brush assembly 1000 can refer to the arrow direction in FIGS. 1 and 2. Specifically, along the rotating direction of the roller body 100, the convex structure 400, the brush condition 200 and the scraping condition 300 are arranged in sequence. When the rolling brush assembly 1000 rotates, the scraping condition 300 is first in contact with the surface of the object to be cleaned, and then the brush condition 200 is in contact with the surface of the object to be cleaned. The scraping condition 300 first pushes away the hair 500 on the surface of the object to be cleaned, and then the brush condition 200 cleans the object to be cleaned. The brush condition 200 is located at the back side of the scraping condition 300, and the scraping condition 300 can also shield the hair 500 for the brush condition 200, so that the hair 500 is more difficult to entangle on the brush condition 200. At the same time, the convex structure 400 is located at the back side of the brush condition 200, and the convex structure 400 is shielded by the brush condition 200, so that the convex structure 400 cannot be in front of the object to be cleaned. The convex structure 400 avoids hindering the brush condition 200 from cleaning the object to be cleaned, ensures that the contact area of the brush condition 200 with the object to be cleaned is larger, and improves the cleaning effect.

[0034] It can be understood that in some embodiments, the minimum distance from the brush condition 200 to the convex structure 400 is less than the minimum distance from the brush condition 200 to the scraping condition 300 in the circumferential direction of the roller body 100. It can also be understood that the brush condition 200 is closer to the convex structure 400 than the scraping condition 300, which can better support the long hair 500, and the hair 500 is not easy to penetrate into the root of the brush condition 200. The certain distance between the brush condition 200 and the scraping condition 300 can ensure better cleaning.

[0035] It can be understood that, as shown in FIG. 1 and FIG. 2, in some embodiments, the outer peripheral wall of the roller body 100 is provided with a mounting portion 110, the mounting portion 110 is arranged to extend outwardly along the radial direction of the roller body 100 and is arranged to extend along the axial direction of the roller body 100, the mounting portion 110 is provided with a first mounting groove 111 and a second mounting groove 112 arranged to extend along the axial direction of the roller body 100, the brush condition 200 is mounted in the first mounting groove 111, and the scraping condition 300 is mounted in the second mounting groove 112, the first mounting groove 111 and the second mounting groove 112 can be square or T-shaped structures, and the first mounting groove 111 and the second mounting groove 112 are arranged to extend along the axial direction of the roller body 100. Since the mounting portion 110 protrudes outwardly along the radial direction of the roller body 100, the mounting portion 110 can also support the hair 500, and part of the structure of the brush condition 200 extends into the first mounting groove 111, the mounting portion 110 blocks the hair 500, so that the hair 500 is not easy to entangle the root position of the brush condition 200. Along the radial direction of the roller body 100, the maximum height of the mounting portion 110 to the axis of the roller body 100 is less than the maximum height of the brush condition 200 to the axis of the roller body 100 and the maximum height of the scraping condition 300 to the axis of the roller body 100, and it can also be understood that, along the radial direction of the roller body 100, the maximum protrusion height of the mounting portion 110 is lower than the maximum protrusion height of the brush condition 200 and the maximum protrusion height of the scraping condition 300, so that the brush condition 200 and the scraping condition 300 can contact the object to be cleaned. The protruding structure 400 is arranged on the mounting portion 110, the protruding structure 400 and the mounting portion 110 can be two separate parts, or the protruding structure 400 and the mounting portion 110 can be an integral structure, and it can be understood that part of the structure of the mounting portion 110 constitutes the protruding structure 400, which is convenient to manufacture.

[0036] It can be understood that, with reference to FIGS. 1 and 2, in some embodiments, the mounting portion 110 includes a first protruding portion 113, a second protruding portion 114, and a third protruding portion 115 arranged in sequence and spaced apart along the rotation direction of the roller body 100, all of which extend outwardly along the radial direction of the roller body 100 and are in the form of a boss structure, which can support the hair 500 and prevent the hair 500 from entering the root of the brush condition 200. The first protruding portion 113 and the second protruding portion 114 define the first mounting groove 111 described above, and the second protruding portion 114 and the third protruding portion 115 define the second mounting groove 112 described above. The first protruding portion 113 is configured as the protruding structure 400, and along the radial direction of the roller body 100, the maximum height of the first protruding portion 113 to the axis of the roller body 100 is greater than the maximum height of the second protruding portion 114 to the axis of the roller body 100 and the maximum height of the third protruding portion 115 to the axis of the roller body 100, which can also be understood as, along the radial direction of the roller body 100, the maximum protrusion height of the first protruding portion 113 is higher than the maximum protrusion height of the second protruding portion 114 and the maximum protrusion height of the third protruding portion 115. For the structure of the mounting portion 110, along the rotation direction of the roller body 100, the first protruding portion 113, the first mounting groove 111, the second protruding portion 114, the second mounting groove 112, and the third protruding portion 115 are arranged in sequence, which can realize the arrangement of the protruding structure 400, the brush condition 200, and the scraping condition 300 in sequence along the rotation direction of the roller body 100.

[0037] It should be noted that, for shorter hair, the scraping condition 300 may not be able to support the short hair due to the certain spacing between the scraping condition 300 and the brush condition 200, and the first protruding portion 113 and the second protruding portion 114 of the present embodiment are respectively located on both sides of the brush condition 200, which can support the short hair and prevent the short hair from entering the root of the brush condition 200.

[0038] It can be understood that, as shown in FIG. 1 and FIG. 2, in some embodiments, the first installation slot 111 and the second installation slot 112 are T-shaped structures, and the brush condition 200 and the scraping condition 300 are also T-shaped structures. Specifically, the first installation slot 111 includes a first segment slot and a second segment slot which are in communication with each other, and the first segment slot and the second segment slot are arranged in sequence in the outward direction of the radial direction of the roller body 100, and the width of the first segment slot is greater than the width of the second segment slot in the circumferential direction of the roller body 100. It can also be understood that the first segment slot is arranged in the circumferential direction of the roller body 100, and the second segment slot is arranged in the radial direction of the roller body 100, thereby forming a T-shaped slot structure. The first slot opening is formed on the side of the installation part 110 away from the roller body 100, and the first slot opening is in communication with the second segment slot. The first slot opening can be understood as the slot opening of the second segment slot. The brush condition 200 can enter the second segment slot through the first slot opening and then enter the first segment slot. Alternatively, the first installation slot 111 forms a first slot opening on both sides of the installation part 110 in the axial direction of the roller body 100. The first slot opening is a T-shaped slot, and the first slot opening is in communication with the first segment slot and the second segment slot. The brush condition 200 can be directly loaded into the first installation slot 111 from the first slot opening. At this time, end covers can be installed at both ends of the roller body 100. The end covers can cover the first slot opening, thereby limiting the brush condition 200 from sliding out of the first installation slot 111 in the axial direction. It can be understood that the second installation slot 112 and the first installation slot 111 have the same structure. The second installation slot 112 includes a third segment slot and a fourth segment slot which are in communication with each other, and the third segment slot and the fourth segment slot are arranged in sequence in the outward direction of the radial direction of the roller body 100. The width of the third segment slot is greater than the width of the fourth segment slot in the circumferential direction of the roller body 100. It can also be understood that the third segment slot is arranged in the circumferential direction of the roller body 100, and the fourth segment slot is arranged in the radial direction of the roller body 100, thereby forming a T-shaped slot structure. The second slot opening is formed on the side of the installation part 110 away from the roller body 100, and the second slot opening is in communication with the fourth segment slot. The second slot opening can be understood as the slot opening of the fourth segment slot. The scraping condition 300 can enter the fourth segment slot through the second slot opening and then enter the third segment slot. Alternatively, the second installation slot 112 forms a second slot opening on both sides of the installation part 110 in the axial direction of the roller body 100. The second slot opening is a T-shaped slot, and the scraping condition 300 can be directly loaded into the second installation slot 112 from the second slot opening. At this time, end covers can be installed at both ends of the roller body 100. The end covers can cover the second slot opening, thereby limiting the scraping condition 300 from sliding out of the second installation slot 112 in the axial direction.

[0039] In this embodiment, the first installation slot 111 and the second installation slot 112 are T-shaped structures. After the brush condition 200 and the scraping condition 300 are loaded into the first installation slot 111 and the second installation slot 112, respectively, the positions of the brush condition 200 and the scraping condition 300 are fixed, the limiting effect is achieved, and the assembly operation is simplified. Part of the structure of the brush condition 200 is located in the first installation slot 111, which can block the root position of the brush condition 200, so that the hair is not easy to entangle at the root position of the brush condition 200.

[0040] It can be understood that, with reference to FIG. 1 and FIG. 2, in some embodiments, the maximum width of the second protruding part 114 is greater than the maximum width of the first protruding part 113 and the maximum width of the third protruding part 115 along the circumference of the roller body 100, which can enhance the structural strength at the position of the second protruding part 114, thereby enhancing the structural strength of the mounting part 110. It should be noted that when the number of cleaning units is multiple groups, the width of the mounting part 110 along the circumference of the roller body 100 should not be too large. In the present embodiment, it can be understood that when the width of the mounting part 110 is certain, the second protruding part 114 can be set to be relatively wide. The second protruding part 114 can separate the scraping condition 300 and the brushing condition 200 by a distance, so that the scraping condition 300 and the brushing condition 200 can both contact the object to be cleaned, and the object to be cleaned can be cleaned respectively, thereby improving the cleaning effect.

[0041] Since the first protruding part 113 is part of the structure of the roller body 100 and has a protruding structure 400, when the roller body 100 is made by an integral molding process, it needs to be considered how to facilitate the first protruding part 113 to be demolded. It can be understood that, with reference to FIG. 1 and FIG. 2, in some embodiments, the first protruding part 113 is provided with a first inclined surface 1131 on the side close to the brushing condition 200, and is provided with a second inclined surface 1132 on the side away from the brushing condition 200. The distance from the first inclined surface 1131 to the second inclined surface 1132 gradually decreases outward along the radial direction of the roller body 100. It can be understood that the first inclined surface 1131 and the second inclined surface 1132 are provided on the first protruding part 113 as a draft angle, which facilitates the mold to be demolded. In addition, when the roller brush assembly 1000 rotates in the rotation direction, the brushing condition 200 contacting the object to be cleaned will bend in the opposite direction of the rotation direction, that is, the brushing condition 200 will lean on the first inclined surface 1131. The first inclined surface 1131 supports the brushing condition 200, which can avoid excessive bending of the brushing condition 200, so that the brushing condition 200 can be better restored to the upright state. In some embodiments, the distance from the first inclined surface 1131 to the brushing condition 200 gradually increases outward along the radial direction of the roller body 100 along the circumference of the roller body 100. It can be understood that a certain gap is left between the brushing condition 200 and the first inclined surface 1131, so that the brushing condition 200 can bend towards the first inclined surface 1131 within a certain range when contacting the surface of the object to be cleaned. This can improve the contact effect of the brushing condition 200 and the object to be cleaned, thereby improving the cleaning effect, but the brushing condition 200 is supported by the first inclined surface 1131 and is not easy to bend excessively.

[0042] It can be understood that, in some embodiments, the minimum distance from the brush condition 200 to the protruding structure 400 in the circumferential direction of the roller body 100 is less than or equal to 5 mm, the minimum distance is a straight-line distance, which ensures that the distance from the brush condition 200 to the protruding structure 400 is small, and the protruding structure 400 is relatively close to the brush condition 200, so that the supporting effect of the protruding structure 400 on the hair can be improved. Specifically, as shown in FIG. 4, the minimum distance from the brush condition 200 to the protruding structure 400 in the circumferential direction of the roller body 100 is L3, and L3≤5 mm. L3 can be 0, that is, the brush condition 200 and the protruding structure 400 are attached together. Specifically, L3 can also be 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm.

[0043] It can be understood that, with reference to FIG. 2, in some embodiments, along the radial direction of the roller body 100, the maximum height of the protruding structure 400 from the axis of the roller body 100 is L1, and the maximum height of the brush condition 200 from the axis of the roller body 100 is L2, and the following condition is satisfied: 0.3 mm≤L2-L1≤3 mm. Specifically, the difference between L2 and L1 can be 0.3 mm, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm, etc. The highest position of the protruding structure 400 is kept at a certain distance from the highest position of the brush condition 200, which ensures that the brush condition 200 can contact the object to be cleaned, and avoids the protruding structure 400 from hindering the brush condition 200 from cleaning the object to be cleaned. In addition, the protruding height of the protruding structure 400 is not too low, which can ensure that the protruding structure 400 supports the hair.

[0044] With reference to FIG. 2, in some embodiments, along the radial direction of the roller body 100, the maximum protruding height of the scraping condition 300 can be lower than the maximum protruding height of the brush condition 200, and the maximum protruding height of the scraping condition 300 is higher than the maximum protruding height of the protruding structure 400, which ensures that the scraping condition 300 can contact the object to be cleaned. In other embodiments, along the radial direction of the roller body 100, the maximum protruding height of the scraping condition 300 can also be higher than the maximum protruding height of the brush condition 200.

[0045] In some embodiments, the brush condition 200 and the scraping condition 300 can be arranged in a straight line along the axial direction of the roller body 100.

The contact area of the brush condition 200 and the scraping condition 300 with the object to be cleaned can be increased, and the cleaning effect can be improved.

[0046] It can be understood that the embodiments of the present application also provide a cleaning device 2000, which can be a vacuum cleaner or a robot sweeper. The cleaning device 2000 includes the roller brush assembly 1000 of the above-mentioned embodiments and a housing 2100. The roller brush assembly 1000 is rotationally connected to the housing 2100. The housing 2100 is provided with a roller brush cavity 2110 and a dust collecting cavity 2120 which are in communication with each other. The roller brush assembly 1000 is located in the roller brush cavity 2110. The cleaning device 2000 further includes a driving motor which can drive the roller brush assembly 1000 to rotate, so that the roller brush assembly 1000 can clean the surface of the object to be cleaned. The cleaning device 2000 is further provided with a fan inside. The fan can generate suction force, so that the dust and garbage on the roller brush assembly 1000 can be sucked into the dust collecting cavity 2120. Since the roller brush assembly 1000 is provided with the scraping condition 300 and the protruding structure 400, the scraping condition 300 and the protruding structure 400 can support the hair 500 or the slender debris, which is equivalent to stretching or opening the hair 500, so that the hair 500 is not easy to entangle at the root of the brush condition 200. With the centrifugal force generated by the rotation of the roller body 100, the hair 500 can gradually be separated from the brush condition 200 and be sucked into the dust collecting cavity 2120 by the suction force of the fan. The problem of the hair 500 entangling the brush condition 200 can be alleviated. The hair 500 entangled on the roller brush assembly 1000 is less, and it is also convenient for the user to clean the roller brush assembly 1000, thereby improving the user experience.
