[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0034] Refer to Figure 1As shown, the roller brush assembly 1000 of the embodiment of the present utility model, the roller brush assembly 1000 includes a roller body 100 and a cleaning unit. The number of cleaning units can be one group or multiple groups, and multiple cleaning units are arranged at intervals along the circumferential direction of the roller body 100. The cleaning unit includes a brush member 200, a scraping member 300, and a convex structure 400. The brush member 200 and the scraping member 300 are used to contact the object to be cleaned and clean the object to be cleaned. The convex structure 400 does not contact the object to be cleaned, and there is a distance between the convex structure 400 and the object to be cleaned. The brush member 200 is connected to the outer peripheral wall of the roller body 100 and extends along the radial direction of the roller body 100. The scraping member 300 is connected to the outer peripheral wall of the roller body 100 and extends along the radial direction of the roller body 100. It should be noted that the brush member 200 includes a plurality of brush strip portions, and the brush strip portions extend along the radial direction of the roller body 100. The plurality of brush strip portions are arranged at intervals along the axial direction of the roller body 100. The brush strip portions can be in a thin strip structure or a thick strip structure, and the brush strip portions can be provided as a brush or a rubber strip. The scraping member 300 can be understood as a leather member or a rubber member. The scraping member 300 extends along the axial direction of the roller body 100. The scraping member 300 can scrape off the dust and garbage on the surface of the object to be cleaned, and it is difficult for the hair 500 to wind around the scraping member 300. The scraping member 300 can play a supporting role for the hair. The cleaning granularity of the brush member 200 is higher than that of the scraping member 300. The brush member 200 and the scraping member 300 are used in combination to enhance the cleaning effect. The brush member 200 and the scraping member 300 can be connected to the roller body 100 by means of glue pasting, snap connection, fastener connection, etc.

[0035] Refer to Figure 1As shown, the protruding structure 400 is connected to the roller body 100, and the protruding structure 400 is arranged along the radial direction of the roller body 100. The protruding structure 400 is also arranged along the axial direction of the roller body 100. In addition, 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. The axis of the roller body 100 can be understood as the rotation 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 as to ensure that the brush condition 200 and the scraping condition 300 can contact the object to be cleaned, and avoid the protruding structure 400 hindering the brush condition 200 and the scraping condition 300 from cleaning. In the circumferential direction of the roller body 100, the raised 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 raised structure 400 can support the hair 500 and other slender debris on both sides of the brush condition 200, which is equivalent to stretching or spreading the hair 500, so that the hair 500 is not easily entangled in the root of the brush condition 200. As the roller body 100 rotates and generates centrifugal force, the hair 500 will gradually break away from the brush condition 200, which can alleviate the problem of hair 500 entangled in the brush condition 200, so that less hair 500 is entangled in the roller brush assembly 1000. The scraping condition 300 and the raised structure 400 support the hair 500, so that there is a larger distance between the hair 500 and the roller body 100. When cleaning the hair 500, the user can find the focus more easily, which is convenient for the user to clean the hair 500 and improves the user experience.

[0036] In some embodiments, the protruding structure 400 and the roller body 100 may be two separate parts, and the protruding structure 400 may be connected to the roller body 100 by means of a mounting structure, for example, by means of gluing, snap connection, fastener connection, welding, etc. In some embodiments, the protruding structure 400 and the roller body 100 may be an integral structure, and the roller body 100 and the protruding structure 400 may be directly manufactured by an integral molding process without the need for installation.

[0037] Reference Figure 1 and Figure 2 As shown, in some embodiments, the number of cleaning units can be three groups, and two adjacent groups of cleaning units can be arranged at an interval of 120 degrees from each other, and the position distribution is relatively balanced, thereby ensuring a better cleaning effect and ensuring that the hair 500 can be supported more evenly.

[0038] It can be understood that in some embodiments, the roller brush assembly 1000 is driven by a driving motor to rotate automatically. The roller brush assembly 1000 drives the brush condition 200 and the scraping condition 300 to rotate together, so that the brush condition 200 and the scraping condition 300 clean the object to be cleaned. The rotation direction of the roller brush assembly 1000 can refer to Figure 1 and Figure 2 the arrow directions in. Specifically, along the rotation 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 roller brush assembly 1000 rotates, the scraping condition 300 first contacts the surface of the object to be cleaned, and then the brush condition 200 contacts the surface of the object to be cleaned. The scraping condition 300 first sweeps 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. And the brush condition 200 is located on the back side of the scraping condition 300. The scraping condition 300 can also help the brush condition 200 block the hair 500, making it difficult for the hair 500 to wind around the brush condition 200. At the same time, the convex structure 400 is located on the back side of the brush condition 200, and the convex structure 400 is blocked by the brush condition 200. The convex structure 400 will not contact the object to be cleaned head-on, preventing the convex structure 400 from hindering the brush condition 200 from cleaning the object to be cleaned, ensuring a relatively large contact area between the brush condition 200 and the object to be cleaned, and improving the cleaning effect.

[0039] It can be understood that in some embodiments, in the circumferential direction of the roller body 100, 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. It can also be understood that relative to the scraping condition 300, the brush condition 200 is closer to the convex structure 400, which can enable the convex structure 400 to better support the slender hair 500, and the hair 500 is not easily inserted into the root of the brush condition 200. A certain distance between the brush condition 200 and the scraping condition 300 can ensure better cleaning.

[0040] It can be understood that referring to Figure 1 and Figure 2As shown, in some embodiments, the outer peripheral wall of the roller body 100 is provided with a mounting portion 110. The mounting portion 110 extends outward in the radial direction of the roller body 100 and also extends in 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 that extend in the axial direction of the roller body 100. The brushing member 200 is mounted in the first mounting groove 111, and the scraping member 300 is mounted in the second mounting groove 112. The first mounting groove 111 and the second mounting groove 112 can be of a square or T-shaped structure and extend in the axial direction of the roller body 100. Since the mounting portion 110 protrudes outward in the radial direction of the roller body 100, the mounting portion 110 can also play a role in supporting the hair 500. Moreover, a part of the structure of the brushing member 200 extends into the first mounting groove 111, and the mounting portion 110 blocks the hair 500, making it difficult for the hair 500 to wind around the root position of the brushing member 200. In the radial direction of the roller body 100, the maximum height from the mounting portion 110 to the axis of the roller body 100 is less than the maximum height from the brushing member 200 to the axis of the roller body 100 and the maximum height from the scraping member 300 to the axis of the roller body 100. It can also be understood that, in the radial direction of the roller body 100, the maximum protruding height of the mounting portion 110 is lower than the maximum protruding height of the brushing member 200 and the maximum protruding height of the scraping member 300, ensuring that the brushing member 200 and the scraping member 300 can contact the object to be cleaned. The protruding structure 400 is provided 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. It can be understood that a part of the structure of the mounting portion 110 constructs the protruding structure 400, which is convenient for manufacturing.

[0041] It can be understood that, with reference to Figure 1 and Figure 2As shown, in some embodiments, the mounting portion 110 includes a first protrusion 113, a second protrusion 114, and a third protrusion 115 that are sequentially arranged at intervals along the rotation direction of the roller body 100. The first protrusion 113, the second protrusion 114, and the third protrusion 115 all protrude radially outward along the roller body 100. The first protrusion 113, the second protrusion 114, and the third protrusion 115 are all boss structures, which can support the hair 500 and prevent the hair 500 from easily entering the root of the brush condition 200. A first mounting groove 111 is defined between the first protrusion 113 and the second protrusion 114, and a second mounting groove 112 is defined between the second protrusion 114 and the third protrusion 115. The first protrusion 113 is configured as a protrusion structure 400. Along the radial direction of the roller body 100, the maximum height of the first protrusion 113 from the axis of the roller body 100 is greater than the maximum height of the second protrusion 114 from the axis of the roller body 100 and the maximum height of the third protrusion 115 from 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 first protrusion 113 is higher than the maximum protruding height of the second protrusion 114 and the maximum protruding height of the third protrusion 115. For the structure of the mounting portion 110, along the rotation direction of the roller body 100, the first protrusion 113, the first mounting groove 111, the second protrusion 114, the second mounting groove 112, and the third protrusion 115 are arranged in sequence, so that the protrusion structure 400, the brush condition 200, and the scraping condition 300 can be arranged in sequence along the rotation direction of the roller body 100.

[0042] It should be noted that for relatively short hair, since there is a certain distance between the scraping condition 300 and the brush condition 200, the scraping condition 300 may not be able to support the short hair. The first protrusion 113 and the second protrusion 114 of this embodiment are respectively located on both sides of the brush condition 200, which can support the short hair and prevent the short hair from easily entering the root of the brush condition 200.

[0043] It can be understood that with reference to Figure 1 and Figure 2As shown, in some embodiments, the first installation groove 111 and the second installation groove 112 are T-shaped structures, and the brushing condition 200 and the scraping condition 300 are also T-shaped structures. Specifically, the first installation groove 111 includes a first section groove and a second section groove that communicate with each other. Along the radially outward direction of the roller body 100, the first section groove and the second section groove are arranged in sequence. Along the circumferential direction of the roller body 100, the width of the first section groove is greater than the width of the second section groove. It can also be understood that the first section groove extends along the circumferential direction of the roller body 100, and the second section groove extends along the radial direction of the roller body 100, thereby forming a T-shaped groove structure. A first notch is formed on the side of the installation portion 110 away from the roller body 100, and the first notch communicates with the second section groove. The first notch can be understood as the notch of the second section groove. The brushing condition 200 can enter the second section groove through the first notch and then enter the first section groove. Or, the first installation groove 111 forms first notches on both sides of the installation portion 110 along the axial direction of the roller body 100. The first notches are T-shaped grooves, and the first notches communicate with the first section groove and the second section groove. The brushing condition 200 can be directly horizontally loaded into the first installation groove 111 from the first notch. At this time, end caps can be installed at both ends of the roller body 100, and the end caps can cover the first notches, thereby restricting the brushing condition 200 from sliding out of the first installation groove 111 along the axial direction. It can be understood that the structure of the second installation groove 112 is the same as that of the first installation groove 111. The second installation groove 112 includes a third section groove and a fourth section groove that communicate with each other. Along the radially outward direction of the roller body 100, the third section groove and the fourth section groove are arranged in sequence. Along the circumferential direction of the roller body 100, the width of the third section groove is greater than the width of the fourth section groove. It can also be understood that the third section groove extends along the circumferential direction of the roller body 100, and the fourth section groove extends along the radial direction of the roller body 100, thereby forming a T-shaped groove structure. A second notch is formed on the side of the installation portion 110 away from the roller body 100, and the second notch communicates with the fourth section groove. The second notch can be understood as the notch of the fourth section groove. The scraping condition 300 can enter the fourth section groove through the second notch and then enter the third section groove. Or, the second installation groove 112 forms second notches on both sides of the installation portion 110 along the axial direction of the roller body 100. The second notches are T-shaped grooves, and the scraping condition 300 can be directly horizontally loaded into the second installation groove 112 from the second notch. At this time, end caps can be installed at both ends of the roller body 100, and the end caps can cover the second notches, thereby restricting the scraping condition 300 from sliding out of the second installation groove 112 along the axial direction.

[0044] In this embodiment, the first installation groove 111 and the second installation groove 112 are T-shaped structures. After the brushing condition 200 and the scraping condition 300 are respectively loaded into the first installation groove 111 and the second installation groove 112, the positions of the brushing condition 200 and the scraping condition 300 can be fixed, achieving a limiting effect and simplifying the assembly operation. Part of the structure of the brushing condition 200 is located in the first installation groove 111, which can block the root position of the brushing condition 200, making it difficult for hair to wrap around the root position of the brushing condition 200.

[0045] It is understandable that, referring to Figure 1 and Figure 2 As shown, in some embodiments, along the circumference of the roller body 100, the maximum width of the second protrusion 114 is greater than the maximum width of the first protrusion 113 and the maximum width of the third protrusion 115, which can enhance the structural strength of the second protrusion 114, thereby enhancing the structural strength of the mounting portion 110. It should be noted that when the number of cleaning units is multiple groups, the width of the mounting portion 110 in the circumference of the roller body 100 should not be too large. This embodiment can be understood as that when the width of the mounting portion 110 is constant, the second protrusion 114 can be set to be relatively wide, and the second protrusion 114 can separate the scraping condition 300 from the brush condition 200 by a distance, so that the scraping condition 300 and the brush condition 200 can both contact the object to be cleaned, and can clean the object to be cleaned separately, thereby improving the cleaning effect.

[0046] Since the first protrusion 113 is a part of the roller body 100 and has the protrusion structure 400, when the roller body 100 is made by an integrated molding process, it is necessary to consider how to facilitate the demolding of the first protrusion 113. Figure 1 and Figure 2 As shown, in some embodiments, a first inclined surface 1131 is provided on the side of the first protrusion 113 close to the brush condition 200, and a second inclined surface 1132 is provided on the side of the first protrusion 113 away from the brush 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. The provision of the first inclined surface 1131 and the second inclined surface 1132 can be understood as providing a draft angle on the first protrusion 113 to facilitate mold demolding. In addition, when the roller brush assembly 1000 rotates in the rotation direction, the brush condition 200 contacts the object to be cleaned and bends in the opposite direction of the rotation direction, that is, the brush condition 200 will lean against the first inclined surface 1131. The first inclined surface 1131 supports the brush condition 200, which can prevent the brush condition 200 from being excessively bent, so that the brush condition 200 can be better restored to an upright state. In some embodiments, the distance from the first inclined surface 1131 to the brush condition 200 in the circumferential direction of the roller body 100 gradually increases radially outwardly of the roller body 100. It can be understood that a certain gap is left between the brush condition 200 and the first inclined surface 1131, so that the brush condition 200 can bend toward the first inclined surface 1131 within a certain range when contacting the surface of the object to be cleaned, which can improve the contact effect between the brush condition 200 and the object to be cleaned and the cleaning effect. However, supported by the first inclined surface 1131, the brush condition 200 is not easy to bend excessively.

[0047] It can be understood that in some embodiments, in the circumferential direction of the roller body 100, the minimum distance from the brush condition 200 to the convex structure 400 is less than or equal to 5 mm, and the minimum distance is the straight-line distance. Ensuring that the distance from the brush condition 200 to the convex structure 400 is small and making the convex structure 400 relatively close to the brush condition 200 can improve the supporting effect of the convex structure 400 on the hair. Specifically, reference can be made to Figure 4 As shown, in the circumferential direction of the roller body 100, the minimum distance from the brush condition 200 to the convex structure 400 is L3, L3 ≤ 5 mm, and L3 can be 0. The brush condition 200 is in contact with the convex structure 400. Specifically, L3 can also be 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm.

[0048] It can be understood that with reference to Figure 2 As shown, in some embodiments, along the radial direction of the roller body 100, the maximum height of the convex 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 it satisfies: 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. Having a certain distance between the highest position of the convex structure 400 and the highest position of the brush condition 200 ensures that the brush condition 200 can contact the object to be cleaned, avoids the convex structure 400 from hindering the cleaning of the object to be cleaned by the brush condition 200, and moreover, the protruding height of the convex structure 400 is not too low, which can ensure that the convex structure 400 supports the hair.

[0049] With reference to Figure 2 As shown, 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 convex structure 400, ensuring that the scraping condition 300 can contact the object to be cleaned. In some 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.

[0050] In some embodiments, along the axial direction of the roller body 100, the brush condition 200 and the scraping condition 300 can be arranged to extend linearly. With reference to Figure 3As shown, in some other embodiments, the brushing condition 200 and the scraping condition 300 can be arranged spirally along the axial direction of the roller body 100, and the spiral direction can be clockwise or counterclockwise. In some embodiments, the roller body 100 has a first position 120, a second position 130, and a third position 140. The first position 120 and the second position 130 are respectively located at both ends of the roller body 100, and the third position 140 is approximately located in the middle of the roller body 100. The brushing condition 200 and the scraping condition 300 spiral from the first position 120 to the third position 140 around a first direction, and the brushing condition 200 and the scraping condition 300 spiral from the third position 140 to the second position 130 around a second direction, where the first direction and the second direction are opposite to each other, that is, the spiral direction from the first position 120 to the third position 140 is opposite to the spiral direction from the third position 140 to the second position 130. It can also be understood that the brushing condition 200 and the scraping condition 300 are spirally formed into a V-shaped structure. This can increase the contact area between the brushing condition 200 and the scraping condition 300 and the object to be cleaned, and improve the cleaning effect.

[0051] It can be understood that the embodiment of the present utility model also provides a cleaning device 2000. The cleaning device 2000 can be a vacuum cleaner or a floor sweeping robot. The cleaning device 2000 includes the roller brush assembly 1000 and the housing 2100 of the above embodiments. The roller brush assembly 1000 is rotatably connected to the housing 2100. The housing 2100 is provided with a roller brush cavity 2110 and a dust collection cavity 2120 that communicate 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, and the driving motor can drive the roller brush assembly 1000 to rotate to clean the surface of the object to be cleaned. A blower is also provided inside the cleaning device 2000, and the blower can generate suction force to suck the dust and garbage on the roller brush assembly 1000 into the dust collection 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 slender sundries, which is equivalent to spreading or opening the hair 500, making it not easy for the hair 500 to wind around the root of the brushing condition 200. With the rotation of the roller body 100, centrifugal force is generated, and the hair 500 will gradually break away from the brushing condition 200 and be sucked into the dust collection cavity 2120 by the suction force of the blower. This can alleviate the problem of the hair 500 winding around the brushing condition 200. There is less hair 500 wound around the roller brush assembly 1000, which also facilitates the user to clean the roller brush assembly 1000 and improves the user experience.
