[0023] Referring to FIGS. 1 to 5 together, in the present application, an anti-winding rotating brush 100 is proposed. The anti-winding rotating brush 100 includes a rotating brush case 1 and a cutting mechanism 2. The rotating brush case 1 includes a chamber 11 and a through groove 12 communicating with the chamber 11. One end of the rotating brush case 1 is a driving end 13, and the driving end 13 is used for connection with a driving member. A fixing portion 14 is movably connected to the other end of the rotating brush case 1, and a fixing shaft 141 extending toward the inside of the chamber 11 is provided on the fixing portion 14. The cutting mechanism 2 includes a connecting member 21 provided in the chamber 11 and a blade 22. The blade 22 is located in the through groove 12 and is movably connected to the rotating brush case 1. The connecting member 21 is movably connected to the fixing shaft 141 and is connected to the blade 22. Here, when the driving end 13 rotates the rotating brush case 1, the blade 22 and the connecting member 21 are rotated, whereby the connecting member 21 is moved along the fixing shaft 141, and the blade 22 is moved along the axial direction of the fixing shaft 141 with respect to the rotating brush case 1 to cut the hair wound around the rotating brush case 1.

[0024] In this embodiment, as shown in Figures 1 to 3, the anti-winding rotating brush 100 consists of a rotating brush case 1 and a cutting mechanism 2. The outside of the rotating brush case 1 is made of rubber for attachment. One end of the rotating brush case 1 is a drive end 13, and the other end is movably connected to a fixed part 14. The drive end 13 is used to connect to the output end of the drive member. The drive member drives the rotating brush case 1 to rotate, thereby winding up debris and facilitating its suction into the debris box, thus achieving a cleaning effect. The rotating brush case 1 has a chamber 11 and a through groove 12. The fixed part 14 is provided with a fixed shaft 141, which extends into the chamber 11 of the rotating brush case 1. The connecting member 21 in the cutting mechanism 2 is movably connected to the fixed shaft 141, and at the same time, the connecting member 21 is further connected to the blade 22. When the drive member drives the rotating brush case 1 to rotate, the fixed shaft 141 provided on the fixed part 14 remains fixed and does not move, while the connecting member 21 rotates in accordance with the rotating brush case 1. At this time, the connecting member 21 rotates relative to the fixed shaft 141, and the fixed shaft 141 biases the connecting member 21 to move along the axial direction of the fixed shaft 141. The blade 22 in the cutting mechanism 2 is located in the through groove 12, and when the rotating brush case 1 rotates, the blade 22 rotates in accordance with the rotating brush case 1, and when the connecting member 21 moves along the axial direction of the fixed shaft 141, the connecting member 21 moves the blade 22 along the axial direction to cut the hair wrapped around the rotating brush case 1, thus preventing the continuous wrapping of hair around the rotating brush case 1 from affecting the rotation of the rotating brush case 1 and the cleaning effect of the rotating brush. In this embodiment, the engagement of the fixed shaft 141 and the connecting member 21 allows the drive member to drive and rotate the rotating brush case 1, while simultaneously moving the blade 22 along the axial direction. In this way, it is not necessary to install the drive member on the blade 22 independently, avoiding the installation of unnecessary and complex structures, and improving the stability of the cutting mechanism 2.

[0025] When actually implemented, the rotating brush case 1 has mounting grooves formed on its outside for attaching rubber, allowing the rubber to be detachably attached to the rotating brush case 1, thereby making it easy to replace the rubber. When the blade 22 is positioned within the through groove 12, at least a portion of it protrudes outside the through groove 12, allowing it to cut hair wrapped around the rotating brush case 1 as the blade 22 moves along the axial direction, and a protective structure can be provided on the side facing outward from the through groove 12 to prevent the blade 22 from injuring a person.

[0026] In one embodiment, as shown in Figures 2, 3, and 5, a fixed rod 15 is provided inside the rotating brush case 1, an arc-shaped groove 221 is provided in the blade 22, and the fixed rod 15 is inserted into the arc-shaped groove 221.

[0027] In this embodiment, the fixing rod 15 is provided inside the chamber 11, and the fixing rod 15 is inserted into the arc-shaped groove 221 of the blade 22, thereby movably connecting the blade 22 to the rotating brush case 1, and enabling the blade 22 to rotate in accordance with the rotating brush case 1. As the blade 22 moves along the axial direction of the fixed shaft 141 by the connecting member 21, the blade 22 is pressed against the fixed rod 15, causing the blade 22 to move in an arc-shaped trajectory. That is, with respect to the blade 22, the fixed rod 15 moves within the arc-shaped groove 221 relative to the blade 22. In this way, the fixed rod 15 not only biases the blade 22 to move axially, but also extends and retracts within the groove 12 through which the blade 22 passes in a direction perpendicular to the axial direction. This results in a better cutting effect on the hair wrapped around the rotating brush case 1, and the arc-shaped groove 221 is smoothly passed through, the resistance of the fixed rod 15's movement relative to the arc-shaped groove 221 is small, the movement of the fixed rod 15 relative to the arc-shaped groove 221 becomes smoother, and the blade 22 does not get caught during movement.

[0028] When actually implemented, the arc angle and arc length of the arc groove 221 can be adjusted according to the actual cutting effect of the blade 22. The larger the arc angle of the arc groove 221, the longer the stroke of the blade 22 as it extends and retracts within the through groove 12. The longer the arc length of the arc groove 221, the smaller the arc angle, and the longer the stroke of the blade 22 as it moves along the axial direction of the fixed shaft 141.

[0029] In one embodiment, as shown in Figures 1 to 3, sawtooth teeth 16 are provided on the outside of the rotating brush case 1, and the sawtooth teeth 16 are uniformly provided on both sides of the through groove 12 along the axial direction, with one end of the sawtooth teeth 16 away from the through groove 12 being smoothly installed.

[0030] In this embodiment, the sawtooth 16 is positioned on the outside of the rotating brush case 1 along the axial direction of the through groove 12, and a recess is formed between the sawtooth 16. When hair is wrapped around the rotating brush case 1, as the rotating brush case 1 rotates, the hair is drawn into the recess, and when the blade 22 moves within the through groove 12, the range of movement of the outwardly protruding portion can be set between one end of the recess close to the through groove 12 and the other end of the sawtooth 16 away from the through groove 12. In this way, the blade 22 can not only cut the hair drawn into the recess, but also not protrude from the sawtooth 16 and injure a person. The end of the sawtooth 16 away from the through groove 12 is set smoothly, and in this way, the hair wrapped around the rotating brush case 1 is easily taken into the recess, improving the efficiency of hair cutting by the cutting mechanism 2.

[0031] In actual implementation, the saw teeth 16 are spaced apart and uniformly placed on both sides of the through groove 12, and the pitch between the saw teeth 16 can be set to 0.1 cm to 0.5 cm, but is not specifically limited to this.

[0032] In one embodiment, as shown in Figures 2, 3, and 5, the rotating brush case 1 includes an upper case 17 and a lower case 18. The upper case 17 is provided with a connecting column 171, and the lower case 18 is provided with a connecting hole 181. The connecting column 171 is inserted into the connecting hole 181, so that the upper case 17 and the lower case 18 surround each other to form a chamber 11 and a through groove 12. The blade 22 is provided with a relief groove 222, which is installed in an arc shape.

[0033] In this embodiment, the rotating brush case 1 consists of an upper case 17 and a lower case 18. The upper case 17 and the lower case 18 are detachably connected via a connecting column 171 and a connecting hole 181. The upper case 17 and the lower case 18 surround each other to form a chamber 11. The connecting column 171 is inserted into the connecting hole 181, thereby connecting the upper case 17 and the lower case 18 while maintaining a certain distance between them and forming a through groove 12. The blade 22 located within the through groove 12 is provided with a relief groove 222 corresponding to the connecting column 171. The relief groove 222 is installed 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. The installation of the connecting column 171 also shares the pressure received by the fixed rod 15 when the blade 22 moves, improving the stability of the blade 22's arc-shaped movement.

[0034] When actually implemented, a screw hole can be provided in the connecting column 171 so that the connecting column 171 and the connecting hole 181 are connected via a screw. The pitch between the upper case 17 and the lower case 18 must be greater than the thickness of the blade 22, providing a certain margin for the movement of the blade 22 within the through groove 12, preventing the blade 22 from getting stuck and affecting the cutting effect of the blade 22.

[0035] In one embodiment, as shown in Figures 2 to 5, a connecting block 211 is provided on the outside of the connecting member 21, and a groove 223 is provided on the blade 22. At least a portion of the connecting block 211 is restricted in position by the groove 223, thereby moving the connecting member 21 along the fixed shaft 141 and moving the blade 22 along the axial direction of the fixed shaft 141.

[0036] In this embodiment, a connecting block 211 is provided on the outside of the connecting member 21, and the connecting block 211 engages with the groove 223 of the blade 22, allowing the connecting block 211 to move the blade 22 along the axial direction, so that the blade 22 cuts the hair wrapped around it. In the direction perpendicular to the axial direction, the stroke of the groove 223 of the connecting block 211 must be greater than the stroke of the blade 22 as it extends and retracts within the through groove 12, thereby preventing the connecting block 211 from slipping out of the groove 223 when the blade 22 moves and affecting the normal operation of the cutting mechanism 2.

[0037] In actual implementation, the connecting block 211 can be molded integrally with the connecting member 21. The cross-sectional shape and size of the connecting block 211 and the groove 223 are the same, and 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 to restrict the position of the connecting block 211 and an arc-shaped groove 221 for inserting the fixing rod 15. This ensures the strength of the blade 22, and the cross-sectional area of ​​the cutting portion gradually decreases from one end closer to the inside of the chamber 11 towards the outside of the through groove 12, and is used to cut wrapped hair.

[0038] In one embodiment, as shown in Figures 2 to 4, a through hole 212 is formed in the connecting member 21, and a closed spiral groove 214 is formed around the through hole 212. A bump 143 is provided on the fixed shaft 141, the fixed shaft 141 is inserted into the through hole 212, and the bump 143 is positioned in the closed spiral groove 214.

[0039] In this embodiment, the fixed shaft 141 is inserted into a through hole 212 formed in the connecting member 21, allowing the connecting member 21 to rotate around the fixed shaft 141. A bump 143 is provided on the fixed shaft 141, and the bump 143 is restricted in position by a closed spiral groove 214. When the connecting member 21 rotates around the fixed shaft 141, the bump 143 moves within the closed spiral groove 214 with the connecting member 21 as the reference material. The trajectory of the bump 143 in the closed spiral groove 214 relative to the connecting member 21 is the actual trajectory of the connecting member 21. Thus, the installation of the closed spiral groove 214 converts the rotation of the connecting member 21 into reciprocating movement along the axial direction of the fixed shaft 141, thereby causing the blade 22 to reciprocate along the axial direction within the groove 12, and performing the function of cutting the wrapped hair.

[0040] To facilitate the installation and production of the connecting member 21 during actual implementation, the connecting member 21 consists of a first block 215 and a second block 216. The first block 215 and the second block 216 are detachably connected and surround each other to form a closed spiral groove 214. The first block 215 and the second block 216 can be detachably connected via bolts or snap-fits, and a fixing groove can be provided on the fixing shaft 141, so that the bump 143 is positioned within the fixing groove, thereby keeping the bump 143 stationary when the connecting member 21 rotates, and the first block 215 and the second block 216 can be installed symmetrically.

[0041] In actual implementation, the closed spiral groove 214 has a first surface and a second surface that are opposite and parallel to each other, and the bump 143 is positioned between the first surface and the second surface, and both the first surface and the second surface move smoothly, thereby reducing the resistance when the bump 143 moves relative to the closed spiral groove 214. Both the first surface and the second surface are provided with a high part and a low part that have a distance difference along the axial direction of the fixed shaft 141, and with respect to the connecting member 21, when the bump 143 moves from the high part to the low part the blade 22 approaches the connecting member 21, and when the bump 143 moves from the low part to the high part the blade 22 moves away from the connecting member 21. Multiple high parts and low parts can be provided within the connecting member 21 at intervals, thereby increasing the frequency of the blade 22 reciprocating along the axial direction of the fixed shaft 141.

[0042] In another embodiment, the bump 143 may be provided on the connecting member 21 and located within the through hole 212, and the closing spiral groove 214 may be installed on the fixed shaft 141, and the bump 143 may be restricted to the position within the closing spiral groove 214, and the rotation of the connecting member 21 can be converted into movement along the axial direction of the fixed shaft 141.

[0043] In one embodiment, as shown in Figures 2 to 4, a slider 213 is provided on the connecting member 21, a chute 19 is provided on the rotating brush case 1, the chute 19 is located inside the chamber 11, and the slider 213 is restricted to being located inside the chute 19.

[0044] In this embodiment, a slider 213 is provided on the outside of the connecting member 21, and the slider 213 is restricted to a position within a chute 19 provided in the rotating brush case 1. This allows the connecting member 21 to rotate in accordance with the rotation of the rotating brush case 1. The chute 19 is installed to extend along the axial direction of the fixed shaft 141, thereby allowing the connecting member 21 to slide along the axial direction of the fixed shaft 141. The length of the chute 19 can be set according to the axial stroke of the connecting member 21, a position regulating groove can be provided on the side wall of the chute 19, and the slider 213 can be provided with a corresponding positioning projection so that the slider 213 is better restricted to a position within the chute 19 and can slide within the chute 19.

[0045] In actual implementation, a chute 19 may be provided in the connecting member 21, and a slider 213 may be installed in the rotating brush case 1 in correspondence with it, with the slider 213 being positioned within the chute 19.

[0046] In one embodiment, as shown in Figures 2 and 3, the fixed portion 14 includes a fixed block 142 and a fixed shaft 141, the fixed block 142 is detachably connected to the fixed shaft 141, the rotating brush case 1 has a port 111 communicating with a chamber 11 and a bearing chamber 112, the fixed shaft 141 is provided passing through the port 111 and the bearing chamber 112, a bearing 113 is provided inside the bearing chamber 112 and is connected to the connecting member 21.

[0047] In this embodiment, the fixed part 14 and the rotating brush case 1 are connected via a bearing 113, thereby allowing the rotating brush case 1 to rotate relative to the fixed part 14. The fixed part 14 consists of a fixed block 142 and a fixed shaft 141. The fixed block 142 is for restricting and fixing the position of the fixed shaft 141. The bearing 113 is positioned within a bearing chamber 112 formed by being surrounded by the rotating brush case 1. The fixed shaft 141 enters the chamber 11 through a port 111 formed in the rotating brush case 1, passes through the bearing 113, and is connected to the connecting member 21.

[0048] In actual implementation, the cross-sectional shape of the fixing block 142 may be triangular or polygonal, which facilitates the installation of fixing grooves of the corresponding shape, and when the fixing block 142 is positioned within the fixing groove, it does not rotate in accordance with the rotating brush case 1. The fixing block 142 and the fixing shaft 141 can be removably connected via bolts or engagement structures, but are not specifically limited here.

[0049] As shown in Figure 1, the present invention further proposes a rotating brush mechanism 200, which includes a mounting case 3 and an anti-wrap rotating brush 100. The specific structure of the anti-wrap rotating brush 100 is described in the above-described embodiment, and since the rotating brush mechanism 200 adopts all the technical ideas of all the above-described embodiments, it will have at least all the beneficial effects of the technical ideas of the above-described embodiments, and therefore will not be described here.

[0050] In this embodiment, the mounting case 3 is surrounded by a mounting chamber 31, to which a drive member is connected. The anti-winding rotating brush 100 is provided in the mounting chamber 31, the fixing portion 14 is connected to the mounting case 3, and the drive end 13 is connected to the output end of the drive member.

[0051] When actually implemented, a drive member mounting chamber 31 is formed at one end of the mounting case 3, the drive member mounting chamber 31 is in communication with the mounting, and the drive member is detachably attached to the drive member mounting chamber 31 and connected to the drive end 13. The fixing portion 14 of the anti-winding rotating brush 100 is connected to the other end of the mounting chamber 31 so that the fixing portion 14 remains fixed and does not move when the drive member drives and rotates the anti-winding rotating brush 100.

[0052] This invention further provides a robotic vacuum cleaner equipped with a rotating brush mechanism 200.
