Description

Technical Field

[0001] This application relates to the field of cleaning equipment, specifically to a roller brush and cleaning equipment. Background Technology

[0002] Cleaning equipment is an electrical appliance that uses a motor to drive blades to rotate at high speed, creating negative air pressure inside the sealed cleaning equipment. This draws dust and debris into the dust collection device and discharges the filtered air at extremely high speed. Cleaning equipment can be classified according to its function into dry cleaning equipment and wet / dry cleaning equipment. Dry cleaning equipment generally includes dust bag type and dust cup type.

[0003] Existing cleaning equipment often gets tangled in hair during operation, and there is no effective way to deal with it. When in use, the brush components on the roller brush adsorb dust and hair on the ground and cleaning surface, but the hair gradually extends and tangles inside the brush components under the influence of airflow and other factors, making subsequent cleaning by the roller brush very difficult.

[0004] In existing cleaning equipment, the roller brush has multiple tracks on its surface for mounting bristle strips and elastic strips. These tracks are often separated, creating grooves that can trap hair. One end of the track extends to the center of the roller, resulting in numerous sharp edges on the surface. When the brush rotates, some hair easily gets caught on these edges, leading to a less than ideal anti-tangling effect. Summary of the Invention

[0005] This application provides a roller brush and cleaning device to solve the problem that hair stuck on the surface of the roller brush in existing cleaning devices leads to poor anti-tangling effect of the roller brush.

[0008] Furthermore, the mounting track also includes a second track that extends from the other end of the roller toward the middle of the roller and is connected to the first track.

[0009] Furthermore, the rotation directions of two adjacent first tracks are opposite; the second end of the first track of one mounting track is connected to the first track of another mounting track adjacent to that mounting track.

[0010] Furthermore, each of the two adjacent first tracks is provided with a protruding first elastic rubber strip; The projections of the two first elastic strips on the axis of the roller at least partially overlap.

[0011] Furthermore, the two adjacent first tracks have the same rotation direction; the second end of the first track of one mounting track is connected to the second track of another mounting track adjacent to that mounting track.

[0012] Furthermore, the roller brush also includes a first elastic rubber strip and a second elastic rubber strip. The first elastic rubber strip protrudes from a first track of a mounting rail; the second elastic rubber strip protrudes from a second track of another mounting rail.

[0013] Furthermore, the first track is provided with a protruding first elastic rubber strip and a first bristle strip that are adjacent to each other; the second track is provided with a protruding second elastic rubber strip and a second bristle strip that are adjacent to each other.

[0014] Furthermore, the first bristle strip is connected to the second bristle strip; the first bristle strip and the second bristle strip form a V-shaped bristle strip.

[0015] Furthermore, the first elastic strip and the second elastic strip are respectively disposed on both sides of the V-shaped brush strip.

[0016] Furthermore, the first track and the second track form an I-shaped structure, a herringbone structure, a T-shaped structure, or a Y-shaped structure.

[0017] Furthermore, the mounting track also includes a second track and a third track. The first end of the second track extends to the other end of the roller, and the second end extends to the middle of the roller; the third track is located between the first track and the second track, and the two ends of the third track extend to the two ends of the roller, respectively.

[0018] Furthermore, the second end of the first track of an installation track is connected to the second or third track of another set of installation tracks.

[0019] Furthermore, the first track is provided with a protruding first elastic rubber strip; the second track is provided with a protruding second elastic rubber strip; and the third track is provided with a protruding bristle strip.

[0020] Furthermore, the bristle strip is V-shaped or S-shaped; the first elastic strip and the second elastic strip are respectively disposed on both sides of the bristle strip.

[0021] Furthermore, the mounting track also includes a third track, the two ends of which extend to the two ends of the roller, respectively.

[0022] Furthermore, the second end of the first track of one set of mounting tracks is connected to the first or third track of another set of mounting tracks.

[0023] Furthermore, the third track is V-shaped, comprising a first track segment and a second track segment that are connected to each other; a portion of the first track is arranged parallel to the first track segment.

[0026] This application also provides a cleaning device, including the aforementioned roller brush.

[0027] In the prior art, when setting bristle strips and elastic rubber strips on a roller brush, the bristle strips and elastic rubber strips are usually installed in a mounting track protruding from the outer circumference of the roller. If a part of the mounting track only extends to the middle of the roller instead of the end of the roller, the end of the mounting track is prone to forming sharp edges. When the roller brush rotates, some hairs are easily caught by the sharp edges.

[0028] This application provides a roller brush and cleaning device. Multiple protruding mounting tracks are provided on the outer circumference of the roller, with one track's end located in the middle of the roller connecting to an adjacent track, thus preventing the sharp edges of the track ends from being exposed on the roller surface. A V-shaped angle is formed at the junction of two tracks. When the roller brush rotates, hair swept from the surface to be cleaned will not get caught on the sharp edges of the tracks, making it easier for the hair to be sucked up by the suction port. A small amount of residual hair will gather inside the V-shaped angle, facilitating user cleaning. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0033] like Figure 1 - Figure 2 As shown, this application provides a cleaning device (not shown), including a floor brush housing 100 and a handle (not shown). A roller brush 200 is installed in the roller brush chamber 104 of the floor brush housing 100. The handle (not shown) is mounted to the floor brush housing 100 via a connecting part 101. The handle (not shown) is equipped with a cleaning device motor (not shown). A roller brush motor (not shown) is installed inside the roller brush 200. The main motor (not shown) of the cleaning device provides suction, and the roller brush motor (not shown) drives the roller brush 200 to rotate. A pipe (not shown) is provided inside the handle (not shown). One end of the brush 200 is connected to the dust collection chamber (not shown) inside the handle (not shown), and the other end is connected to the suction port 102 of the brush housing 100. The suction port 102 is located on one side wall of the roller brush chamber 104, and the comb teeth 103 of the brush housing 100 are also located on this side wall. The comb teeth 103 are located above the suction port 102. When the roller brush 200 is driven to rotate, the hair wrapped around the roller brush 200 is combed off by the comb teeth 103 inside the brush housing 100. The combed hair is sucked into the suction port 102 by the suction force generated by the main motor (not shown) and enters the dust collection chamber (not shown) through the pipe (not shown).

[0034] In existing cleaning equipment, the roller brush surface has multiple tracks for mounting bristle strips and elastic strips. Grooves between these tracks can easily trap hair. One end of the track extends to the middle of the roller, resulting in numerous sharp edges on the roller surface. When the roller brush rotates, some hair easily gets caught on these edges, leading to a less than ideal anti-tangling effect. To solve these problems, this application includes the following technical features.

[0035] Example 1 like Figure 3 As shown, this embodiment provides a roller brush 200, including a roller 201 and two mounting rails 210 protruding from the surface of the roller 201. Specifically, the roller 201 includes a cylindrical surface 202, and the mounting rails 210 protrude from the cylindrical surface 202. In other embodiments, there may be two or more mounting rails 210.

[0036] In this embodiment, there are two mounting tracks 210. The first track 211 of one mounting track 210 extends from the first end 203 of the roller to the middle of the roller 201, and the first track 211 of the other mounting track 210 extends from the second end 204 of the roller to the middle of the roller 201. Specifically, the first end 212 of the first track extends to one end of the roller 201, and the second end 213 of the first track extends to the other end of the roller 201.

[0037] like Figure 3As shown, each mounting track 210 has a first track 211 with a parallel elastic rubber strip 230 and a bristle strip 220. The projections of the two elastic rubber strips 230 on the axis of the roller 201 at least partially overlap. The sum of the projection lengths of the two first tracks 211 belonging to the two mounting tracks 210 on the axis of the roller 201 is greater than or equal to the length of the roller 201. The sum of the projection lengths of the two elastic rubber strips 230 or bristle strips 220 installed on the two mounting tracks 210 on the axis of the roller 201 is greater than or equal to the length of the roller 201. This ensures that from one end of the roller 201 to the other end, there is at least one bristle strip 220 and at least one elastic rubber strip 230 arranged in parallel, so that no cleaning dead corners are left in the coverage area of ​​the roller brush 200.

[0038] The elastic strip 230 is composed of a rubber strip and a fabric strip disposed on the rubber strip. In the rotation direction of the roller 201, the fabric strip is located in front of the rubber strip, so that the fabric strip can contact the hair on the brush strip 220 before the rubber strip, allowing the hair to adhere to the fabric strip. The surface of the rubber strip is smooth, so the hair cannot adhere to the rubber strip. The rubber strip has edges, which are used to support the hair on the roller brush 200 and prevent the hair from getting tangled on the roller brush.

[0039] The bristle strip 220 is used to clean dust and hair from the surface to be cleaned. It can be formed by several bristle bundles, or it can be a continuous felt strip, or it can be made of other materials or in other forms, which are not limited here.

[0040] The bristle strips 220 and the two elastic rubber strips 230 can form a staggered structure. When the roller brush 200 rotates, the hair on the surface of the roller 201 will find support points along the circumference of the roller 201 and form entanglement. This staggered structure will hinder the hair entanglement process, thereby improving the anti-hair entanglement ability of the roller brush 200.

[0041] Existing technologies typically employ a rubber strip on each side of the bristle bar, extending to both ends of the roller to prevent hair from tangling at the bristle roots. However, because the rubber strip is relatively stiff, it generates significant noise upon contact with the surface being cleaned. In this embodiment, the two elastic rubber strips 230 are preferably arranged such that the projection of one elastic strip's length onto the roller axis is equivalent to 50% of the roller length, and the projection of the other elastic strip's length onto the roller axis is equivalent to 70% of the roller length. The elastic strips are wound around the roller surface along a spiral line. Even if the spiral direction angle is the same as that of existing rubber strips, the elastic strips in this embodiment are much shorter than those in the prior art, resulting in significantly less noise and a simpler and more convenient installation process.

[0042] With the elastic rubber strip shortened, the mounting track used to install it naturally also becomes shorter. The mounting track doesn't necessarily need to extend to the end of the roller; it only needs to extend to the middle of the roller. This creates a new technical problem. Because the mounting track protrudes from the roller surface, and one end of the first track only extends to the middle of the roller, the end of the first track forms a protruding edge exposed on the roller surface. During the rotation of the roller brush, some hair easily gets caught on the edge of the first track end, making it difficult to be sucked away by the suction port, thus leading to another form of hair entanglement. To solve this problem, this embodiment provides the following technical solution.

[0043] The second end 213 of the first track of the first mounting track 210 is connected to the first track 211 of the second mounting track 210 adjacent to it. At the connection point, the two first tracks 211 form a V-shaped angle 217. This structure ensures that the second end 213 of the first track of the first mounting track 210 is not idle and does not expose any sharp edges. When the roller brush 200 rotates, hair will not get caught on the sharp edges. Some hair is sucked away by the suction port 102, and a small amount of residual hair will gather inside the V-shaped angle 217, making it easy for the user to clean it themselves.

[0044] In this embodiment, the rotation directions of two adjacent first tracks 211 are opposite. This arrangement of the two first tracks 211 forms a "shear force field" on the roller 201. When flexible debris such as hair comes into contact with the roller brush 200, it will be pulled in opposite directions by the first elastic rubber strips 231 on the two first tracks 211. The opposite arrangement produces mechanical action in opposite directions, applying alternating stress and shear force to the hair, disrupting the stability of continuous hair winding, causing the hair to be thrown off or cut off, and significantly improving the anti-winding ability of the roller brush 200.

[0045] The advantage of this embodiment is that the two connected mounting tracks 210 do not expose any sharp edges. When the roller brush 200 rotates, the hair will not get caught on the sharp edges. Some of the hair is sucked away by the suction port 102, and a small amount of residual hair will gather inside the V-shaped angle 217, which is convenient for the user to clean up. The first track 211, which is connected to each other, rotates in opposite directions, forming a "shear force field" that applies alternating stress and shear force to the hair, destroying the stability of the continuous entanglement of the hair, causing the hair to be thrown off or cut off, which significantly improves the anti-entanglement ability of the roller brush 200.

[0046] Example 2 This embodiment includes most of the technical features of implementation 1, and the difference is that, for example... Figure 4 As shown, this embodiment provides a roller brush 200, including a roller 201 and two mounting tracks 210 protruding from the surface of the roller 201. In other embodiments, there may be multiple mounting tracks 210.

[0047] The roller 201 includes a cylindrical surface 202, which is the outer peripheral surface of the roller 201; each mounting track 210 is used to mount the bristle strip 220 and / or the elastic rubber strip 230, and the mounting track 210 protrudes from the cylindrical surface 202. In this embodiment, the working principle and technical effect of the bristle strip 220 and the elastic rubber strip 230 are the same as in Embodiment 1, and will not be described again here.

[0048] Each mounting track 210 includes a first track 211 and a second track 214. The first end 212 of the first track extends to the first end 203 of the roller, and the second end 213 of the first track extends to the second end 204 of the roller. The second track 214 extends from the second end 204 of the roller to the middle of the roller 201 and connects to the first track 211. The first track 211 and the second track 214 form an I-shaped structure, a herringbone structure, a T-shaped structure, or a Y-shaped structure.

[0049] like Figure 4 As shown, each mounting track 210 is equipped with a bristle strip 220 and two elastic rubber strips 230 located on both sides of the bristle strip 220. The two ends of the bristle strip 220 extend to both ends of the roller 201, with one part located on the first track 211 and the other part on the second track 214. The two elastic rubber strips 230 are respectively installed on the first track 211 and the second track 214, and are located on both sides of the bristle strip 220. The sum of the projected lengths of the two elastic rubber strips 230 on the axis of the roller 201 is greater than or equal to the length of the roller 201. This ensures that from one end of the roller 201 to the other, there are at least one bristle strip 220 and at least one elastic rubber strip 230 arranged side-by-side, leaving no cleaning dead corners within the coverage area of ​​the roller brush 200, thereby improving the anti-hair entanglement capability of the roller brush 200.

[0050] Because the mounting track protrudes from the cylinder surface, and one end of the first track only extends to the middle of the cylinder, the end of the first track easily forms a protruding edge. During the rotation of the roller brush, some hair is easily caught on the edge and is difficult to be sucked away by the suction port, resulting in hair entanglement. To solve this problem, this embodiment provides the following technical solution.

[0051] like Figure 4 As shown, the rotation directions of two adjacent first tracks 211 are opposite; the second end 213 of the first track of the first mounting track 210 is connected to the first track 211 of the second mounting track 210 adjacent to it. The two first tracks 211 form a V-shaped angle 217 at their connection point. This structure ensures that the second end 213 of the first track of the first mounting track 210 is not idle and does not expose any sharp edges. When the roller brush 200 rotates, hair will not get caught on the sharp edges. Some hair is sucked away by the suction port, and a small amount of residual hair will gather inside the V-shaped angle 217, making it easy for the user to clean it themselves.

[0052] In this embodiment, the opposite rotation directions of two adjacent first tracks 211 form a "shear force field" on the roller 201. When flexible debris such as hair comes into contact with the roller brush 200, it will be pulled in opposite directions by the first elastic rubber strips 231 on the two first tracks 211. The opposite arrangement produces opposite mechanical forces, applying alternating stress and shear force to the hair, disrupting the stability of the continuous winding of the hair, causing the hair to be thrown off or cut off, and significantly improving the anti-winding ability of the roller brush 200.

[0053] Furthermore, the first track 211 is provided with a protruding and adjacent first elastic rubber strip 231 and a first bristle strip 221; the second track 214 is provided with a protruding and adjacent second elastic rubber strip 232 and a second bristle strip 222. The first track 211 and the second track 214 are spirally arranged on the cylindrical surface 202 of the roller 201, which increases the wrapping area of ​​the bristle strip 220 and the elastic rubber strip 230 on the cylindrical surface 202 of the roller 201. The projections of the first elastic rubber strip 231 and the second elastic rubber strip 232 on the axis of the roller 201 at least partially overlap, and the projections of the first bristle strip 221 and the second bristle strip 222 on the axis of the roller 201 at least partially overlap. When the roller 201 rotates at high speed, the bristle strip 220 and the elastic rubber strip 230 on the first track 211 and the second track 214 will not leave cleaning dead corners in the coverage area of ​​the roller brush 200, thus avoiding cleaning dead corners in the roller brush 200.

[0054] In this embodiment, the positional relationship between two adjacent items with a spacing of less than 5mm is defined as close to each other. Therefore, the distance between the center point of any segment of the first elastic adhesive strip 231 and the center point of any segment of the first bristle strip 221 is between 1mm and 5mm; the distance between the center point of any segment of the adhesive strip and the center point of any segment of the second bristle strip 222 is between 1mm and 5mm.

[0055] like Figure 4 As shown, the first bristle strip 221 is connected to the second bristle strip 222; the first bristle strip 221 and the second bristle strip 222 form a V-shaped bristle strip 220. The V-shaped bristle strip 220 can increase the contact area between the first bristle strip 221 and the second bristle strip 222 and the surface to be cleaned, thereby improving cleaning efficiency. The first elastic strip 231 and the second elastic strip 232 are respectively provided on both sides of the V-shaped bristle strip 220.

[0056] In this embodiment, the independently set first elastic strip 231 and second elastic strip 232 are less rigid than a single V-shaped elastic strip 230, making them easier to install. Furthermore, due to the lower rigidity of the first and second elastic strips 231 and 232, the friction between them and the surface to be cleaned is reduced, resulting in lower noise. The independently set first and second elastic strips, along with the bristle strip 220, form a staggered structure. This staggered structure disrupts the stability of the contact point between the roller brush 200 surface and the hair, making it difficult for the hair to find a stable "point of contact," preventing the hair from starting its entanglement process and avoiding entanglement at the root of the bristle strip 220, thus improving the anti-entanglement capability of the roller brush 200.

[0057] Other technical features of this embodiment are the same as those of Embodiment 1. The advantage of this embodiment is that the second end 213 of the first track of the first mounting track 210 is connected to the first track 211 of the second mounting track 210 adjacent to the first track 210. This structure ensures that the second end 213 of the first track of the mounting track 210 is not idle, thus avoiding the problem of garbage and hair getting stuck. Furthermore, the opposite rotation directions of the two adjacent first tracks 211 form a "shearing force field" on the roller 201. The first elastic rubber strip 231, the second elastic rubber strip, and the bristle strip 220 on the mounting track 210 form a staggered structure. The "shearing force field" and the staggered structure prevent hair from getting tangled at the root of the bristle strip 220, greatly improving the anti-tangling ability of the roller brush 200.

[0058] Example 3 This embodiment includes most of the technical features of embodiment 2, the difference being that, for example Figures 4-5 As shown, the two adjacent first tracks 211 rotate in the same direction; the second end 213 of the first track of the first mounting track 210 is connected to the second track 214 of the second mounting track 210 adjacent to the first track 210; a first elastic rubber strip 231 protrudes from the first track 211 of one mounting track 210; a second elastic rubber strip 232 protrudes from the second track 214 of the other mounting track 210. The first elastic rubber strip 231 on the first track 211 of one mounting track 210 and the second elastic rubber strip 232 on the second track 214 of the other mounting track 210 achieve full coverage of the cylindrical surface 202 of the roller brush 200, avoiding cleaning dead corners of the roller brush 200.

[0059] Because the mounting track protrudes from the cylinder surface, and one end of the first track only extends to the middle of the cylinder, the end of the first track easily forms a protruding edge. During the rotation of the roller brush, some hair is easily caught on the edge and is difficult to be sucked away by the suction port, resulting in hair entanglement. To solve this problem, this embodiment provides the following technical solution.

[0060] like Figures 4-5 As shown, the two adjacent first tracks 211 rotate in the same direction; the second end 213 of the first track of the first mounting track 210 connects to the second track 214 of the second mounting track 210 adjacent to it. At the connection point, the first track of the first mounting track 210 and the second track 214 of the second mounting track 210 form a V-shaped angle 217. This structure ensures that the second end 213 of the first track of the first mounting track 210 is not idle and does not expose any sharp edges. When the roller brush rotates, hair will not get caught on the sharp edges. Some hair is sucked away by the suction port, and a small amount of residual hair will gather inside the V-shaped angle 217, making it easy for the user to clean it themselves.

[0061] Other technical features of this embodiment are the same as those of Embodiment 1. The advantage of this embodiment is that the two connected mounting rails 210 prevent the ends of the first rail 211 of the mounting rail 210 from being exposed. When the roller brush 200 rotates, the hair will not be caught on the edges. Some hair is sucked away by the suction port 102, and a small amount of residual hair will gather inside the V-shaped angle 217, which is convenient for users to clean themselves.

[0062] Example 4 This embodiment includes most of the technical features of embodiment 2, the difference being that, for example Figure 4 as well as Figures 6-7 As shown, each mounting track 210 includes a first track 211, a second track 214, and a third track 240. The first end 212 of the first track extends to the first end 203 of the roller, and the second end 213 of the first track extends to the middle of the roller 201. The first end 215 of the second track extends to the second end 204 of the roller, and the second end 216 of the second track extends to the middle of the roller 201. The third track 240 is located between the first track 211 and the second track 214, and both ends of the third track 240 extend to both ends of the roller 201, respectively. The second end 216 of the second track of the first mounting track 210 is connected to the second track 214 or the third track 240 of the second mounting track 210. The first track 211 and the second track 214 are separated from each other, and the second track 214 and the third track 240 are separated from each other.

[0063] like Figure 4 as well as Figures 6-7As shown, each mounting track 210 is equipped with a bristle strip 220 and two elastic rubber strips 230 located on both sides of the bristle strip 220. The bristle strip 220 is located on the third track 240, and both ends of the bristle strip 220 extend to both ends of the roller 201. The two elastic rubber strips 230 are respectively installed on the first track 211 and the second track 214, and are located on both sides of the bristle strip 220. The sum of the projected lengths of the two elastic rubber strips 230 on the axis of the roller 201 is greater than or equal to the length of the roller 201, so that from one end of the roller 201 to the other end, there are at least one bristle strip 220 and at least one elastic rubber strip 230 arranged side by side, so that no cleaning dead corners are left in the coverage area of ​​the roller brush 200, thereby improving the anti-hair entanglement ability of the roller brush 200.

[0064] Because the mounting track protrudes from the cylinder surface, and one end of the first track only extends to the middle of the cylinder, the end of the first track easily forms a protruding edge. During the rotation of the roller brush, some hair is easily caught on the edge and is difficult to be sucked away by the suction port, resulting in hair entanglement. To solve this problem, this embodiment provides the following technical solution.

[0065] like Figure 4 as well as Figures 6-7 As shown, the second end 213 of the first track of the first mounting track 210 is connected to the second track of the second mounting track 210 adjacent to it. A V-shaped angle 217 is formed at the junction of the first track of the first mounting track 210 and the second track of the second mounting track 210. This structure ensures that the second end 213 of the first track of the first mounting track 210 is not idle and does not expose any sharp edges. When the roller brush rotates, hair will not get caught on the sharp edges; some hair will be sucked away by the suction port, and a small amount of residual hair will gather inside the V-shaped angle 217, making it easy for the user to clean it themselves.

[0066] Furthermore, the bristle strip 220 is V-shaped or S-shaped: the first elastic rubber strip 231 and the second elastic rubber strip 232 are respectively disposed on both sides of the bristle strip 220. The V-shaped or S-shaped bristle strip 220 can increase the contact area between the bristle strip 220 and the surface to be cleaned, thereby improving the cleaning efficiency of the roller brush 200. The independently disposed first elastic rubber strip 231 and second elastic rubber strip 232 have less rigidity than a whole V-shaped or S-shaped elastic rubber strip 230, making them easier to install. Moreover, due to the lower rigidity of the first elastic rubber strip 231 and second elastic rubber strip 232, the friction between the first elastic rubber strip 231 and second elastic rubber strip 232 and the surface to be cleaned is smaller, resulting in lower noise.

[0067] Other technical features of this embodiment are the same as those of Embodiment 1. The advantage of this embodiment is that the second end 213 of the first track of the first mounting track 210 is connected to the first track 211 of the second mounting track 210 adjacent to the first track 210. This structure ensures that the second end 213 of the first track of the mounting track 210 is not idle, thus avoiding the problem of garbage and hair getting stuck. Furthermore, the opposite rotation directions of the two adjacent first tracks 211 form a "shearing force field" on the roller 201. The first elastic rubber strip 231, the second elastic rubber strip, and the bristle strip 220 on the mounting track 210 form a staggered structure. The "shearing force field" and the staggered structure prevent hair from getting tangled at the root of the bristle strip 220, greatly improving the anti-tangling ability of the roller brush 200.

[0068] Example 5 This embodiment includes most of the technical features of embodiment 2, the difference being that, for example Figure 4 as well as Figures 8-9 As shown, each mounting track 210 includes a first track 211 and a third track 240. The first end 212 of the first track extends to the first end 203 of the roller, and the second end 213 of the first track extends to the middle of the roller 201. The two ends of the third track 240 extend to the two ends of the roller 201 respectively. The second end 216 of the second track of the first mounting track 210 is connected to the first track 211 or the third track 240 of the second mounting track 210.

[0069] like Figure 4 as well as Figures 8-9 As shown, each mounting track 210 is equipped with a bristle strip 220 and two elastic rubber strips 230 located on both sides of the bristle strip 220. The bristle strip 220 is located on the third track 240, and both ends of the bristle strip 220 extend to both ends of the roller 201. The two elastic rubber strips 230 are respectively installed on the first track 211 and the third track 240, and are respectively located on both sides of the bristle strip 220. The sum of the projected lengths of the two elastic rubber strips 230 on the axis of the roller 201 is greater than or equal to the length of the roller 201, so that from one end of the roller 201 to the other end, there are at least one bristle strip 220 and at least one elastic rubber strip 230 arranged side by side, so that no cleaning dead corners are left in the coverage area of ​​the roller brush 200, thereby improving the anti-hair entanglement ability of the roller brush 200.

[0070] Because the mounting track protrudes from the cylinder surface, and one end of the first track only extends to the middle of the roller, protruding edges are easily formed at the end of the first track. During the rotation of the roller brush, some hair is easily caught on the edges and is difficult to be sucked away by the suction port, resulting in hair entanglement. To solve this problem, this embodiment provides the following technical solution.

[0071] like Figure 4 as well as Figures 8-9 As shown, the second end 213 of the first track of the first mounting track 210 is connected to the third track 240 of the second mounting track 210 adjacent to it. A V-shaped angle 217 is formed at the junction of the first track 211 of the first mounting track 210 and the third track 240 of the second mounting track 210. This structure ensures that the second end 213 of the first track of the first mounting track 210 is not idle and does not expose any sharp edges. When the roller brush 200 rotates, hair will not get caught on the sharp edges; some hair will be sucked away by the suction port, and a small amount of residual hair will gather inside the V-shaped angle 217, making it easy for the user to clean it themselves.

[0072] Furthermore, the third track 240 is V-shaped and includes a first track segment 241 and a second track segment 242 that are connected to each other; a portion of the first track 211 is arranged in parallel with the first track segment 241.

[0073] In this embodiment, the bristle strips 220 installed on the V-shaped third track 240 are V-shaped. The V-shaped bristle strips 220 can increase the contact area between the bristle strips 220 and the surface to be cleaned, thereby improving the cleaning efficiency of the roller brush 200. The second elastic rubber strip 232 on the second track segment 242 is arranged in parallel with some of the bristle strips 220 on the second track segment 242. The independently arranged first elastic rubber strip 231 and second elastic rubber strip 232 have less rigidity than a whole V-shaped elastic rubber strip 230, making them easier to install. Furthermore, due to the lower rigidity of the first elastic rubber strip 231 and second elastic rubber strip 232, the friction between the first elastic rubber strip 231 and second elastic rubber strip 232 and the surface to be cleaned is smaller, resulting in lower noise.

[0074] Other technical features of this embodiment are the same as those of Embodiment 1. The advantage of this embodiment is that the second end 213 of the first track of the first mounting track 210 is connected to the first track 211 of the second mounting track 210 adjacent to the first track 210. This structure ensures that the second end 213 of the first track of the mounting track 210 is not idle, thus avoiding the problem of garbage and hair getting stuck. Furthermore, the opposite rotation directions of the two adjacent first tracks 211 form a "shearing force field" on the roller 201. The first elastic rubber strip 231, the second elastic rubber strip, and the bristle strip 220 on the mounting track 210 form a staggered structure. The "shearing force field" and the staggered structure prevent hair from getting tangled at the root of the bristle strip 220, greatly improving the anti-tangling ability of the roller brush 200.

[0075] In the prior art, when setting bristle strips and elastic rubber strips on a roller brush, the bristle strips and elastic rubber strips are usually installed in a mounting track protruding from the outer circumference of the roller. If a part of the mounting track only extends to the middle of the roller instead of the end of the roller, the end of the mounting track is prone to forming sharp edges. When the roller brush rotates, some hairs are easily caught by the sharp edges.

[0076] The advantage of this application lies in providing a roller brush and cleaning device. Multiple protruding mounting tracks are provided on the outer circumference of the roller, with one track's end in the middle of the roller connecting to an adjacent track, thus preventing the sharp edges of the track ends from being exposed on the roller surface. A V-shaped angle is formed at the junction of two tracks. When the roller brush rotates, hair swept from the surface to be cleaned will not get caught on the sharp edges of the tracks, making it easier for the hair to be sucked away by the suction port. A small amount of residual hair will gather inside the V-shaped angle, facilitating user cleaning.

[0077] The above provides a detailed description of the roller brush and cleaning device provided by this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
