Abstract

This invention belongs to the field of electrical equipment technology, specifically relating to a roller brush and a cleaning device and system incorporating the roller brush. The roller brush body has a cutting groove; protective teeth at least partially connect to the opening of the cutting groove; a first blade is placed within the brush body; and a second blade is placed within the brush body. The cutting edges of both the first and second blades at least partially protrude from the cutting groove and are lower than the protective teeth. The first blade oscillates relative to the brush body, and the second blade oscillates relative to the first blade. This invention, through the reciprocating oscillation of the second blade relative to the first blade, can cut away any debris that may be entangled on the roller brush, thereby reducing the amount of debris on the roller brush surface and improving the cleanliness of the roller brush surface.

Claims

1. A roller brush rotatably connected to a cleaning device, the roller brush comprising: The brush body has a cutting groove. Protective teeth, at least partially connected to the opening of the cutting groove; a first blade body, placed inside the brush body; A second blade is placed inside the brush body, wherein the cutting edges of the first blade and the second blade at least partially protrude from the cutting groove, the cutting edges of the first blade and the second blade are lower than the protective teeth, the first blade oscillates back and forth relative to the brush body, and the second blade oscillates back and forth relative to the first blade.

2. The roller brush as described in claim 1, further comprising: A linkage assembly is disposed within the brush body and connects the first blade and the second blade respectively, thereby driving the second blade to reciprocate relative to the first blade.

3. The roller brush as described in claim 2, wherein, The linkage assembly includes: a first linkage, including a first end and a second end, the first end of the first linkage being eccentrically and rotatably connected to the first blade body via a first rotating shaft; a second linkage, including a first end, a middle portion and a second end, the first end of the second linkage being rotatably connected to the second end of the first linkage via a second rotating shaft, the middle portion of the second linkage being connected to the second blade body via a third rotating shaft, and the second end of the second linkage being rotatably connected to the brush body via a fourth rotating shaft, wherein the second rotating shaft, the third rotating shaft and the fourth rotating shaft are not located in a straight line.

4. The roller brush as described in claim 3, wherein, There are two second blades, which are arranged opposite each other on both sides of the fourth rotating shaft. The middle part of the second connecting rod is connected to one of the two second blades through the third rotating shaft. The connecting rod assembly also includes a fourth connecting rod, which includes a first end and a second end. The first end of the fourth connecting rod is fixedly connected to the second end of the second connecting rod. The second end of the fourth connecting rod is rotatably connected to the other of the two second blades through a fifth rotating shaft.

5. The roller brush as described in claim 4, wherein, The linkage assembly further includes: a third linkage, including a first end and a second end, wherein the first end of the third linkage is rotatably connected to the second pivot, and the second end of the third linkage is rotatably connected to the fourth pivot.

6. The roller brush as described in claim 4, wherein, The first blade has cutting edges on both sides, and the cutting edges on both sides of the first blade are in close contact with the second blade.

7. The roller brush as described in claim 6, wherein, An elastic element is provided between at least one of the first and second blades and the sidewall of the cutting groove.

8. A roller brush as described in any one of claims 1 to 7, wherein, A plurality of first blades are spaced apart along the axial direction of the brush body, and each first blade is eccentrically provided with a drive shaft. The plurality of drive shafts are rotatably connected to a transmission component, which reciprocates within the brush body.

9. The roller brush as described in claim 8, wherein, A wear-resistant component is provided between the transmission component and the first cutter body.

10. The roller brush according to any one of claims 1 to 7, further comprising: A transmission component is disposed within the brush body and connected to the first blade body, thereby driving the first blade body to reciprocate relative to the brush body.

11. The roller brush as described in any one of claims 1 to 7, further comprising a drive assembly, the drive assembly including: A driving component, including a rotatable driving part; The connecting shaft is eccentrically connected to the first cutter body; A swing arm includes a first end and a second end, wherein the first end of the swing arm is rotatably connected to the drive unit, and the second end of the swing arm is rotatably connected to the connecting shaft.

12. The roller brush as described in claim 11, wherein, The driving component includes: a worm gear mechanism, including a worm wheel and a worm, the worm being rotatable relative to the brush body, the worm wheel meshing with the worm, the worm wheel being rotatably arranged within the brush body, wherein the worm wheel is configured as the driving part.

13. A cleaning device comprising a roller brush as described in any one of claims 1 to 12.

14. A cleaning system comprising a base station for cooperative use and a cleaning device as described in claim 13, the cleaning device being adapted to dock with or disconnect from the base station.
