[0032] Embodiment 1

[0033] See also Figure 1-Figure 4 As shown in the figure, a roller brush for a vacuum cleaner that can automatically clean hair includes a roller brush base 100, an electric rotating rod 200 is installed on the inner wall of the roller brush base 100, and a roller brush body 300 is arranged on the outer side of the electric rotating rod 200;

[0034] A cleaning assembly 400 is provided inside the roller brush base 100, and the cleaning assembly 400 includes a bevel gear transmission group 410. The bevel gear transmission group 410 is provided with two groups. The two groups of bevel gear transmission groups 410 are symmetrically distributed about the roller brush body 300 and are respectively located at the front end and the rear end of the roller brush body 300. The bevel gear transmission group 410 includes a bevel gear 1 411, a rotating rod 1 412 and a bevel gear 2 413. The bevel gear 1 411 is fixedly connected to the electric rotating rod 200, the rotating rod 1 412 is rotatably connected to the roller brush base 100, the bevel gear 2 413 is fixedly connected to the bevel gear 1 411, the bevel gear 2 413 is located at the side position of the bevel gear 1 411, and the bevel gear 2 413 is in a meshing state with the bevel gear 1 411. The outer side of the rotating rod 1 412 is fixedly connected with a power gear 420, and the inner wall of the roller brush base 100 is slidably connected with a force gear rod 430. When the electric rotating rod 200 is started, the roller brush body 300 is driven to rotate for dust collection. At this time, the bevel gear 1 411 in one of the bevel gear transmission groups 410 rotates clockwise under the action of the electric rotating rod 200, so that the bevel gear 1 411 drives the bevel gear 2 413 meshing with it to rotate counterclockwise, and the bevel gear 1 411 rotating clockwise in the other bevel gear transmission group 410 drives the bevel gear 2 413 meshing with it to rotate clockwise. The bevel gear 2 413 continues to drive the rotating rod 1 412 fixedly connected to it to rotate, so that the rotating rod 1 412 drives the power gear 420 fixedly connected to it to rotate. Because only half of the teeth are provided on the two power gears 420, and the two groups of teeth are located at different positions on the two power gears 420, when one of the power gears 420 is meshed with the force gear rod 430, the other is in an idling state. In this way, the two power gears 420 with opposite rotation directions can drive the force gear rod 430 to move back and forth. The side of the force-bearing toothed rod 430 is fixedly connected to a transmission rod 440, and the side of the transmission rod 440 is fixedly connected to a cutter head 450. When the force-bearing toothed rod 430 moves back and forth, the force-bearing toothed rod 430 drives the transmission rod 440 fixedly connected thereto to move, and the transmission rod 440 drives the cutter head 450 fixedly connected thereto to move back and forth, so as to cut and clean the hair rolled up on the roller brush body 300, thereby improving the use efficiency.

[0035] When in use, the electric rotating rod 200 is started to drive the roller brush body 300 to rotate for dust collection. At this time, the bevel gear 1 411 in one of the bevel gear transmission groups 410 rotates clockwise under the action of the electric rotating rod 200, so that the bevel gear 1 411 drives the bevel gear 2 413 meshing with it to rotate counterclockwise, and the bevel gear 1 411 rotating clockwise in the other bevel gear transmission group 410 drives the bevel gear 2 413 meshing with it to rotate clockwise, and the bevel gear 2 413 continues to drive the rotating rod 1 412 fixedly connected to it to rotate, so that the rotating rod 1 412 drives the power gear fixedly connected to it. The wheel 420 rotates. Since only half of the teeth are provided on the two power gears 420, and the two sets of teeth are respectively located at different positions on the two power gears 420, when one of the power gears 420 is engaged with the force-bearing gear rod 430, the other is in an idling state. In this way, the two power gears 420 with opposite rotation directions can drive the force-bearing gear rod 430 to move back and forth, so that the force-bearing gear rod 430 drives the transmission rod 440 fixedly connected thereto to move, and the transmission rod 440 drives the cutter head 450 fixedly connected thereto to move back and forth, so as to cut and clean the hair rolled into the roller brush body 300.

[0036] To further improve the cleaning effect, see Figure 1-Figure 6 As shown in the figure, a knocking assembly 500 is arranged inside the roller brush base 100. The knocking assembly 500 includes a fixed rod 510. The fixed rod 510 is located at the bottom of the roller brush base 100. The fixed rod 510 and the roller brush base 100 are in a fixed state. The rear end of the fixed rod 510 is rotatably connected to the rotating rod 2 520. A conveyor belt 530 is arranged outside the electric rotating rod 200. One end of the conveyor belt 530 is located outside the electric rotating rod 200, and the other end of the conveyor belt 530 is located outside the rotating rod 200. When the electric rotating rod 200 rotates, the conveyor belt 530 arranged outside the electric rotating rod 200 is coordinated. Since one end of the conveyor belt 530 is located outside the electric rotating rod 200, and the other end of the conveyor belt 530 is located outside the rotating rod 200, the rotating rod 2 520 connected to the electric rotating rod 200 through the conveyor belt 530 rotates. The rear end of the rotating rod 2 520 is fixedly connected to an elastic cam 540. When the second rotating rod 520 rotates, the second rotating rod 520 drives the elastic cam 540 fixedly connected thereto to rotate, and the rotating elastic cam 540 strikes the cutter head 450, shaking off the cut hair that may be attached to the cutter head 450, thereby further improving the use efficiency.

[0037] When in use, when the electric rotating rod 200 rotates, it cooperates with the conveyor belt 530 set on the outside of the electric rotating rod 200. Because one end of the conveyor belt 530 is located on the outside of the electric rotating rod 200, and the other end of the conveyor belt 530 is located on the outside of the rotating rod 200, the rotating rod 202 520 connected to the electric rotating rod 200 through the conveyor belt 530 rotates, and the rotating rod 202 520 then drives the elastic cam 540 fixedly connected to it to rotate, and the rotating elastic cam 540 knocks on the cutter head 450, shaking off the cut hair that may be attached to the cutter head 450.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
