Roller brushes, cleaning equipment and cleaning systems

Abstract

This invention belongs to the field of household cleaning technology, specifically relating to a roller brush, cleaning device, and cleaning system. The roller brush includes a blade body and a transmission component. The blade body has a driven part, and the transmission component is disposed within the brush body. The transmission component includes a cam; the cam rotates in conjunction with the driven part, driving the blade body to reciprocate relative to the brush body. This roller brush can cut away any tangled material that may become entangled on it, preventing interference with its operation and improving its cleaning efficiency.

Claims

1. A roller brush rotatably connected to a cleaning device, the roller brush comprising: The brush body has a cutting groove; the protective teeth are at least partially connected to the opening of the cutting groove. A blade body is disposed within the brush body, the cutting edge of the blade body at least partially protruding from the cutting groove, the cutting edge of the blade body being lower than the protective teeth, the blade body including a driven part; and a transmission member disposed within the brush body, the transmission member including a cam, wherein the cam rotates in conjunction with the driven part to drive the blade body to reciprocate relative to the brush body.

2. The roller brush as described in claim 1, wherein, The cam has two or more positioning parts on its periphery, the two or more positioning parts are spaced apart along the axial direction of the cam, and at least a portion of the two or more positioning parts are staggered along the periphery of the cam.

3. The roller brush as described in claim 2, wherein, At least a portion of the circumference of the cam is provided with a first protrusion, the first protrusion having two or more positioning portions in the axial direction of the cam, the cutter body is provided with a first recess, at least a portion of the first protrusion rotates within the first recess, and the first recess is configured as the driven portion.

4. The roller brush as described in claim 3, wherein, At least a portion of the first protrusion is a combination of one or more of a spiral structure, a slope structure, and an arc structure.

5. The roller brush as described in claim 2, wherein, At least a portion of the circumference of the cam is provided with a second recess, the second recess having two or more positioning portions in the axial direction of the cam, the cutter body is provided with a second protrusion, at least a portion of the second protrusion rotates within the second recess, and the second recess is configured as the driven portion.

6. The roller brush as described in claim 5, wherein, At least a portion of the second recess is a combination of one or more of a spiral structure, a slope structure, and an arc structure.

7. A roller brush as described in any one of claims 2 to 6, wherein, The device includes two or more blades, at least one of which is provided with a driven part. The cam and the blade with the driven part are provided in a one-to-one correspondence. Two or more positioning parts on the cam cooperate with the driven parts on the corresponding blades to drive the corresponding blades to reciprocate relative to the brush body.

8. The roller brush as described in claim 7, wherein, In the two or more blades, at least one blade is fixed relative to the brush body, or both of the two or more blades reciprocate relative to the brush body; or the two or more blades move relative to each other.

9. The roller brush as described in claim 8, wherein, The cams that cooperate with the two relatively movable blades are arranged symmetrically about an axis perpendicular to the drive shaft. The drive shaft is rotatably disposed in the brush body. At least one of the cams is connected to the drive shaft, and the cams can rotate synchronously with the drive shaft.

10. The roller brush as described in claim 8, wherein, Two or more of the aforementioned blades reciprocate in the same direction and have a speed difference.

11. The roller brush as described in claim 7, wherein, The blade body is provided with a first guide portion, and the brush body is provided with a second guide portion. One of the first guide portion and the second guide portion is a guide shaft, and the other is a guide recess. The guide recess is along an axial direction parallel to the drive shaft, and the guide shaft reciprocates within the guide recess. The drive shaft is rotatably disposed within the brush body. At least one cam is connected to the drive shaft, and the cam rotates synchronously with the drive shaft. The brush body is provided with multiple guide shafts, and the line connecting at least two guide shafts intersects the drive shaft.

12. The roller brush as described in claim 7, wherein, Two or more blades are stacked together, wherein at least one of the two outer blades has an elastic element on its outer side.

13. A roller brush as described in any one of claims 1 to 6, wherein, The transmission component includes a power input shaft, a reduction mechanism, and a power output shaft connected in sequence, and the cam is connected to the power output shaft.

14. A roller brush as described in any one of claims 1 to 6, wherein, The protective teeth are connected to the periphery of the brush body and are positioned on at least a portion of the periphery of the cutting groove. The protective teeth protrude from the brush body and cover the portion of the blade that protrudes from the cutting groove.

15. A cleaning device comprising a roller brush as described in any one of claims 1 to 14.

16. A cleaning system comprising a base station for cooperative use and a cleaning device as described in claim 15, the cleaning device being adapted to dock with or disconnect from the base station.
