Roller brushes, cleaning equipment and cleaning systems

Abstract

This invention relates to a roller brush, a cleaning device, and a cleaning system. The roller brush includes: a brush body having a cutting groove; protective teeth at least partially connected to the opening of the cutting groove; a first blade body disposed within the brush body; and a second blade body disposed within the brush body, wherein the cutting edges of the first and second blade bodies at least partially protrude from the cutting groove, the cutting edges of the first and second blade bodies are lower than the protective teeth, and the second blade body reciprocates relative to the first blade body.

Claims

1. A roller brush for rotatably attaching 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; and the first blade is placed inside the brush body. The first and second blades are placed inside the brush body. The cutting edges of the first and second blades at least partially protrude from the cutting groove. The cutting edges of the first and second blades are lower than the protective teeth. The second blade is capable of reciprocating relative to the first blade.

2. The roller brush as described in claim 1, further comprising: A transmission assembly is disposed within the brush body and is connected to the second blade body to drive the second blade body to reciprocate relative to the first blade body.

3. The roller brush as described in claim 2, wherein, The transmission assembly includes: a driving member, the driving member including a rotatable driving part; a first driving shaft, the first driving shaft being eccentrically connected to the driving part of the driving member; a second driving shaft, the second driving shaft being eccentrically connected to the second cutter body; and a swing arm, the swing arm including a first end and a second end, the first end of the swing arm being rotatably connected to the first driving shaft, and the second end of the swing arm being rotatably connected to the second driving shaft.

4. The roller brush as described in claim 3, wherein, A wear-resistant component is provided between the swing arm and at least one of the first drive shaft and the second drive shaft, the wear-resistant component including a copper sleeve or a bearing.

5. The roller brush as described in claim 3, wherein, The driving component includes: a power input shaft perpendicular to the central axis of the second cutter body; a worm gear mechanism including a worm wheel and a worm, the worm being connected to the power input shaft; and a first transmission wheel drivingly connected to the worm wheel, the first transmission wheel being configured as the driving part.

6. The roller brush as described in claim 5, wherein, The driving component further includes: a central gear, which is coaxially connected to the worm gear and drives the first transmission wheel.

7. The roller brush as described in claim 6, wherein, The driving component further includes a second transmission wheel, which is connected to the central gear and the first transmission wheel respectively, wherein the radius of the second transmission wheel is smaller than the radius of the first transmission wheel.

8. A roller brush as described in any one of claims 5 to 7, wherein, The power input shaft is rotatably connected to the brush body.

9. A roller brush as described in any one of claims 1 to 7, wherein, The first blade and the second blade are fitted together.

10. The roller brush as described in claim 9, wherein, The brush body is provided with a receiving cavity, the first blade and the second blade are disposed in the receiving cavity, and an elastic member is provided between the outer side of at least one of the first blade and the receiving cavity.

11. The roller brush as described in claim 10, wherein, The elastic element has a non-circular structure.

12. A cleaning device comprising a roller brush as described in any one of claims 1 to 11.

13. A cleaning system comprising a base station for cooperative use and cleaning equipment as described in claim 12, wherein, The base station is equipped with a docking station, and the cleaning equipment can be docked to the docking station, so that the base station can perform at least one of the following operations on the cleaning equipment: charging, dust collection, and cleaning.
