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 is rotatably connected to the cleaning device, and the brush body has a cutting groove; protective teeth are at least partially connected to the opening of the cutting groove; a first blade is disposed within the brush body; and a second blade is disposed within the brush body, wherein 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, and the first blade rotates relative to the brush 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 blade and the second blade are placed inside the brush body. The cutting edges of the first blade and the second blade protrude at least partially from the cutting groove. The cutting edges of the first blade and the second blade are lower than the protective teeth. The first blade rotates relative to the brush body.

2. The roller brush as described in claim 1 further includes a transmission component disposed within the brush body, the transmission component connecting the first blade and the second blade, the transmission component being used to drive the first blade to rotate relative to the brush body.

3. The roller brush as described in claim 2, wherein, The transmission component includes: a driving member, the driving member including a rotatable driving part; a main gear connected to the driving part; a driving shaft rotatably disposed within the brush body, on which the first blade and the second blade are spaced apart; a first driven gear mounted on the driving shaft and engaging with the conical surface of the main gear; and a second driven gear mounted on the driving shaft and engaging with the conical surface of the main gear.

4. The roller brush as described in claim 3, wherein, The brush body includes a fixing member, the middle part of the drive shaft is rotatably connected to the fixing member, and the two ends of the drive shaft protrude from the two ends of the fixing member to connect the first blade body and the second blade body respectively.

5. The roller brush as described in claim 4, wherein, The drive shaft includes: a first shaft body, the first end of which protrudes from the fixing member and is connected to the first cutter body; and a second shaft body, the first end of which protrudes from the fixing member and is connected to the second cutter body, wherein the second ends of the first shaft body and the second ends of the second shaft body are together disposed in the fixing member.

6. The roller brush as described in claim 1, further comprising: A third blade and a fourth blade are fixedly disposed within the brush body and are symmetrical about the axis of the first blade and the second blade about the roller brush, wherein the third blade and the fourth blade at least partially protrude from the cutting groove.

7. The roller brush as described in claim 6, wherein, The third and fourth blades are in contact; when the first blade rotates relative to the brush body, the third blade rotates relative to the brush body.

8. The roller brush as described in claim 7, wherein, The brush body is provided with a receiving part, the cutting groove communicates with the receiving part, the third blade and the fourth blade are fixedly disposed in the receiving part, and an elastic member is provided between the outer side of at least one of the third blade and the fourth blade and the receiving part.

9. The roller brush as described in claim 3, wherein, The drive unit includes a power input shaft, a reduction mechanism, and a power output shaft connected in sequence, wherein the power output shaft is configured as the drive unit.

10. The roller brush as described in claim 9, wherein, The reduction mechanism includes a planetary gear reduction mechanism.

11. A cleaning device comprising a roller brush as described in any one of claims 1 to 10.

12. A cleaning system comprising a base station used in conjunction with the cleaning equipment as described in claim 11, the cleaning equipment being able to leave or enter the base station.
