Multi-bearing rolling brush assembly and cleaning robot

Abstract

The invention discloses a multi-bearing rolling brush assembly and a cleaning robot. The rolling brush assembly comprises a rolling brush tooth box work box, a power box, a rolling brush tooth box fixing shaft assembled on a cover face of a rolling brush tooth box, a first dust-proof part, a second dust-proof part and a third dust-proof part, wherein a wheel type structure is assembled between therolling brush tooth box work box and the power box, the wheel type structure sleeves in an assembly groove position at one end of a rolling brush shaft, a rotation ring of the first dust-proof part and a rotation ring of the second dust-proof part are in interference contact with the corresponding side faces of the wheel type structure, a fixed ring of the first dust-proof part sleeves the rolling brush tooth box fixing shaft, and a fixed ring of the second dust-proof part is fixed on the cover face of the brush tooth box work box; and a rotation ring of the third dust-proof part is assembledon a rotation shaft at the other end of the rolling brush shaft, and a fixed ring of the third dust-proof part is fixed on the rolling brush cover face of the rolling brush tooth box when the rollingbrush shaft is assembled in the rolling brush tooth box, so that the rolling brush assembly runs stably and quietly.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to a multi-bearing rolling brush assembly and a cleaning robot. Background technique [0002] At present, with the popularization of smart home appliances, smart sweepers have entered thousands of households. The structure of the existing intelligent sweeper roller brush tooth box is generally as follows: the teeth of the roller brush motor drive the synchronous wheel fixed on the ball bearing to rotate through the belt transmission, and the synchronous wheel directly drives the rotation of the hair-planting roller brush shaft, and friction of the roller brush shaft often occurs A series of problems, such as rubber parts and roller brush shaft jumping, hair entanglement, and dust intrusion into the roller brush tooth box through the gap, lead to excessive current and abnormal operation of the roller brush tooth box components. In severe cases, the sweeper cannot be used. ...
