[0032] 1 to 5 , the present application proposes an anti-entanglement roller brush 100, which includes a roller brush shell 1 and a cutting assembly 2. The roller brush shell 1 is provided with a cavity 11 and a through groove 12 connected to the cavity 11. One end of the roller brush shell 1 is a driving end 13, which is used to connect with a driving member. The other end of the roller brush shell 1 is movably connected with a fixing portion 14, and the fixing portion 14 is provided with a fixed shaft 141 extending toward the cavity 11. The cutting assembly 2 includes a connecting member 21 and a blade 22 provided in the cavity 11. The blade 22 is located in the through groove 12 and is movably connected to the roller brush shell 1. The connecting member 21 is movably connected to the fixed shaft 141 and is connected to the blade 22; wherein the driving end 13 drives the roller brush shell 1 to rotate, thereby driving the blade 22 and the connecting member 21 to rotate, so that the connecting member 21 moves along the fixed shaft 141, and drives the blade 22 to move axially relative to the roller brush shell 1 along the fixed shaft 141 to cut the hair entangled in the roller brush shell 1.

[0033] In this embodiment, as shown in Figures 1 to 3, the anti-entanglement roller brush 100 consists of a roller brush shell 1 and a cutting assembly 2. The outer side of the roller brush shell 1 is used to install rubber. One end of the roller brush shell 1 is a driving end 13, and the other end is movably connected to the fixing portion 14. The driving end 13 can be used to connect the output end of the driving member. The driving member can drive the roller brush shell 1 to rotate to roll up the debris and facilitate suction into the debris box, thereby forming a cleaning effect. The roller brush shell 1 is formed with a cavity 11 and a through groove 12. The fixing portion 14 is provided with a fixed shaft 141. The fixed shaft 141 extends into the cavity 11 of the roller brush shell 1. The connecting member 21 in the cutting assembly 2 is movably connected to the fixed shaft 141. At the same time, the connecting member 21 is also connected to the The blade 22 is connected. When the driving member drives the roller brush housing 1 to rotate, the fixed shaft 141 provided on the fixing portion 14 is fixed and the connecting member 21 rotates with the roller brush housing 1. At this time, the connecting member 21 rotates relative to the fixed shaft 141, and the fixed shaft 141 pushes the connecting member 21 to move axially along the fixed shaft 141. The blade 22 in the cutting assembly 2 is located in the through groove 12. When the roller brush housing 1 rotates, the blade 22 rotates with the roller brush housing 1. When the connecting member 21 moves axially along the fixed shaft 141, the connecting member 21 drives the blade 22 to move axially, cutting the hair wrapped around the roller brush housing 1, preventing the hair from being continuously wrapped around the roller brush housing 1 and affecting the rotation of the roller brush housing 1 and the cleaning effect of the roller brush. In this embodiment, through the cooperation of the fixed shaft 141 and the connecting member 21, the driving member drives the roller brush housing 1 to rotate while also enabling the blade 22 to move axially. In this way, there is no need to provide a separate driving member for the blade 22, avoiding the provision of a redundant and complex structure, and improving the stability of the cutting assembly 2.

[0034] In actual implementation, an installation groove for the rubber is formed on the outside of the roller brush shell 1, so that the rubber can be detachably installed on the roller brush shell 1, which facilitates the replacement of the rubber; when the blade 22 is located in the through groove 12, at least part of it extends out of the through groove 12, so that the blade 22 can cut the hair wrapped around the roller brush shell 1 when it moves axially, and a protective structure can be set on the side of the through groove 12 facing outward to prevent the blade 22 from hurting people.

[0035] In one embodiment, as shown in FIG. 2 , FIG. 3 and FIG. 5 , a fixing rod 15 is provided in the roller brush housing 1 , an arcuate groove 221 is provided on the blade 22 , and the fixing rod 15 is passed through the arcuate groove 221 .

[0036] When the blade 22 is moved axially along the fixed axis 141 by the connecting member 21, the blade 22 is pressed by the fixing rod 15, so that the blade 22 moves in an arc trajectory, that is, with the blade 22 as a reference, the fixing rod 15 moves relative to the blade 22 in the arc groove 221. In this way, the fixing rod 15 not only pushes the blade 22 to move in the axial direction, but also enables the blade 22 to move telescopically in the through groove 12 in a direction perpendicular to the axial direction, thereby achieving a better cutting effect on the hair wrapped around the brush housing 1. The arc groove 221 has a smooth transition, and the movement resistance of the fixing rod 15 relative to the arc groove 221 is small, so that the movement of the fixing rod 15 relative to the arc groove 221 is smoother, and the blade 22 will not get stuck during movement.

[0037] In actual implementation, the curvature and arc length of the arc groove 221 can be adjusted according to the actual cutting effect of the blade 22. The larger the curvature of the arc groove 221, the longer the extension and retraction stroke of the blade 22 in the through groove 12. The longer the arc length of the arc groove 221 and the smaller the curvature, the longer the stroke of the blade 22 moving along the axial direction of the fixed axis 141.

[0038] In one embodiment, as shown in FIG. 1 to FIG. 3 , the roller brush housing 1 is provided with serrations 16 , which are evenly arranged on both sides of the through slot 12 along the axial direction, and the end of the serrations 16 away from the through slot 12 is smoothly arranged.

[0039] In this embodiment, the serrations 16 are arranged axially along the through slot 12 on the outside of the roller brush housing 1. Recesses are formed between the serrations 16. When hair is entangled in the roller brush housing 1, it becomes entangled in the recesses as the roller brush housing 1 rotates. As the blade 22 moves within the through slot 12, the extended portion of the blade 22 can move within a range between the end of the recess near the through slot 12 and the end of the serrations 16 away from the through slot 12. This allows the blade 22 to cut hair entangled in the recesses without extending beyond the serrations 16, thereby preventing injury. The end of the serrations 16 away from the through slot 12 is rounded, making it easier for hair entangled in the roller brush housing 1 to become incorporated into the recesses, thereby improving the efficiency of the cutting assembly 2 in cutting hair.

[0040] In actual implementation, the serrations 16 are evenly and spaced apart on both sides of the through slot 12 . The spacing between the serrations 16 can be set between 0.1 cm and 0.5 cm, which is not specifically limited here.

[0041] In one embodiment, as shown in Figures 2, 3 and 5, the roller brush shell 1 includes an upper shell 17 and a lower shell 18, the upper shell 17 is provided with a connecting column 171, and the lower shell 18 is provided with a connecting hole 181, the connecting column 171 is inserted into the connecting hole 181, so that the upper shell 17 and the lower shell 18 are enclosed to form a cavity 11 and a through groove 12, and the blade 22 is provided with a clearance groove 222, and the clearance groove 222 is arranged in an arc shape.

[0042] In this embodiment, the roller brush shell 1 is composed of an upper shell 17 and a lower shell 18, and the upper shell 17 and the lower shell 18 are detachably connected by a connecting column 171 and a connecting hole 181. The upper shell 17 and the lower shell 18 enclose a cavity 11, and the connecting column 171 is plugged into the connecting hole 181, so that when the upper shell 17 and the lower shell 18 are connected, a certain distance is maintained between the upper shell 17 and the lower shell 18 to form a through groove 12. The blade 22 located in the through groove 12 is provided with a clearance groove 222 corresponding to the connecting column 171, and the clearance groove 222 is arranged in an arc shape, thereby reducing the resistance of the connecting column 171 to the blade 22 when the blade 22 moves relative to the connecting column 171. At the same time, the setting of the connecting column 171 shares the pressure on the fixing rod 15 when the blade 22 moves, thereby improving the stability of the arc-shaped movement of the blade 22.

[0043] In actual implementation, a threaded hole can be set in the connecting column 171 so that the connecting column 171 and the connecting hole 181 can be connected by screws; the distance between the upper shell 17 and the lower shell 18 should be greater than the thickness of the blade 22, providing a certain margin for the movement of the blade 22 in the through groove 12, thereby preventing the blade 22 from getting stuck when moving in the through groove 12 and affecting the cutting effect of the blade 22.

[0044] In one embodiment, as shown in Figures 2 to 5, a connecting block 211 is provided on the outer side of the connecting member 21, and the blade 22 is provided with a groove 223. At least part of the connecting block 211 is limited in the groove 223, so that the connecting member 21 moves along the fixed axis 141, driving the blade 22 to move axially along the fixed axis 141.

[0045] In this embodiment, a connecting block 211 is provided on the outer side of the connecting member 21. The connecting block 211 cooperates with the groove 223 of the blade 22 so that the connecting block 211 can drive the blade 22 to move in the axial direction, and the blade 22 cuts the entangled hair; in the direction perpendicular to the axial direction, the stroke of the connecting block 211 in the groove 223 should be greater than the stroke of the blade 22 extending and retracting in the through slot 12, thereby preventing the connecting block 211 from falling out of the groove 223 when the blade 22 moves, thereby affecting the normal operation of the cutting assembly 2.

[0046] In actual implementation, the connecting block 211 can be integrally formed with the connecting member 21, and the cross-sectional shape and size of the connecting block 211 and the groove 223 are consistent. The blade 22 includes a fixing portion 14 and a cutting portion. The fixing portion 14 has a uniform thickness and is provided with a groove 223 for limiting the connecting block 211 and an arc-shaped groove 221 for the fixing rod 15 to pass through, so as to ensure the strength of the blade 22. The cross-sectional area of ​​the cutting portion gradually decreases from one end close to the cavity 11 to the outside of the through groove 12, and is used to cut entangled hair.

[0047] In one embodiment, as shown in Figures 2 to 4, the connecting member 21 is formed with a through hole 212, and a closed spiral groove 214 is formed around the through hole 212. The fixed shaft 141 is provided with a protrusion 143, the fixed shaft 141 is passed through the through hole 212, and the protrusion 143 is limited to the closed spiral groove 214.

[0048] In this embodiment, the fixed shaft 141 is passed through the through hole 212 formed in the connecting member 21 so that the connecting member 21 can rotate around the fixed shaft 141. A protrusion 143 is provided on the fixed shaft 141, and the protrusion 143 is limited to the closed spiral groove 214. When the connecting member 21 rotates around the fixed shaft 141, with the connecting member 21 as a reference, the protrusion 143 moves in the closed spiral groove 214, and the movement trajectory of the protrusion 143 relative to the connecting member 21 in the closed spiral groove 214 is the actual movement trajectory of the connecting member 21. In this way, the rotation of the connecting member 21 is converted into a reciprocating movement along the axial direction of the fixed shaft 141 through the provision of the closed spiral groove 214, thereby driving the blade 22 to reciprocate axially in the through groove 12, thereby achieving the effect of cutting entangled hair.

[0049] In actual implementation, the connecting member 21 is composed of a first block 215 and a second block 216 to facilitate the installation and production of the connecting member 21. The first block 215 and the second block 216 are detachably connected and enclosed to form a closed spiral groove 214. The first block 215 and the second block 216 can be detachably connected by bolts or snaps. A fixing groove can be set on the fixed shaft 141, and the protrusion 143 is limited in the fixing groove so that the protrusion 143 remains stationary when the connecting member 21 rotates. The first block 215 and the second block 216 can be symmetrically arranged.

[0050] In actual implementation, the closed spiral groove 214 has a first surface and a second surface that are arranged relative to and parallel to each other, and the protrusion 143 is limited between the first surface and the second surface. The first surface and the second surface are both smoothly transitioned to reduce the resistance of the protrusion 143 when it moves relative to the closed spiral groove 214. The first surface and the second surface are both provided with a high portion and a low portion with a distance difference along the axial direction of the fixed axis 141. When the connecting member 21 is used as a reference, when the protrusion 143 moves from the high portion to the low portion, the blade 22 approaches the connecting member 21, and when the protrusion 143 moves from the low portion to the high portion, the blade 22 moves away from the connecting member 21; in the connecting member 21, multiple high portions and low portions can be arranged at intervals, so that the frequency of the axial reciprocating movement of the blade 22 along the fixed axis 141 can be increased.

[0051] In another embodiment, the protrusion 143 can be provided on the connecting member 21 and located in the through hole 212. The closed spiral groove 214 can be provided on the fixed shaft 141. The protrusion 143 is limited in the closed spiral groove 214 and can also convert the rotation of the connecting member 21 into axial movement along the fixed shaft 141.

[0052] In one embodiment, as shown in FIG. 2 to FIG. 4 , the connecting member 21 is provided with a slider 213 , the roller brush housing 1 is provided with a slide groove 19 , the slide groove 19 is located in the cavity 11 , and the slider 213 is confined in the slide groove 19 .

[0053] In this embodiment, a slider 213 is provided on the outside of the connecting member 21, and the slider 213 is limited in the slide groove 19 provided in the roller brush shell 1, so that when the roller brush shell 1 rotates, it can drive the connecting member 21 to rotate accordingly. The slide groove 19 extends along the axial direction of the fixed shaft 141, so that the connecting member 21 can slide along the axial direction of the fixed shaft 141. The length of the slide groove 19 can be set according to the stroke of the connecting member 21 in the axial direction. The side wall of the slide groove 19 can be provided with a limiting groove, and the slider 213 can be provided with a corresponding limiting protrusion, so that the slider 213 can be better limited in the slide groove 19 and slide in the slide groove 19.

[0054] In actual implementation, the connecting member 21 may be provided with a slide groove 19 , and a slider 213 is correspondingly provided in the roller brush housing 1 , and the slider 213 may be limited in the slide groove 19 .

[0056] In this embodiment, the fixed part 14 and the roller brush shell 1 are connected by a bearing 113, so that the roller brush shell 1 can rotate relative to the fixed part 14. The fixed part 14 is composed of a fixed block 142 and a fixed shaft 141. The fixed block 142 is used to limit and fix the fixed shaft 141. The bearing 113 is limited in the bearing cavity 112 formed by the roller brush shell 1. The fixed shaft 141 extends into the accommodating cavity 11 through the opening 111 formed by the roller brush shell 1, and is connected to the connecting member 21 through the bearing 113.

[0057] In actual implementation, the cross-sectional shape of the fixing block 142 can be triangular or polygonal to facilitate the provision of a fixing groove of a corresponding shape, so that when the fixing block 142 is restrained in the fixing groove, it does not rotate with the roller brush housing 1. The fixing block 142 and the fixed shaft 141 can be detachably connected by bolts or a snap-fit ​​structure, which is not specifically limited here.
