Rotatable rolling brush assembly and cleaning device

Abstract

The invention provides a rotatable rolling brush assembly for a cleaning device. The rotatable rolling brush assembly comprises a first rolling brush and a second rolling brush which are arranged at intervals. A plurality of groups of first bristles are arranged on the first rolling brush. A plurality of groups of second bristles are arranged on the second rolling brush. The first rolling brush and the second rolling brush can respectively rotate around a first axis and a second axis along two opposite directions. In the advancing direction of the cleaning device, the first rolling brush is arranged in front of the second rolling brush. At least part of the first bristles and at least part of the second bristles are overlapped and continuously meshed under the driving of rotation of the first rolling brush and the second rolling brush. The second rolling brush is arranged in a floating mode in the vertical direction relative to the first rolling brush. According to the cleaning device,the two sets of rolling brushes are arranged and the bristles of the two sets of rolling brushes are arranged in a meshed mode. The dust is prevented from splashing during sweeping. The rear rollingbrush further has the lifting function to reduce the resistance caused by the cleaning device working on blankets or similar environments.

Description

technical field [0001] The invention relates to a rotatable rolling brush assembly and a cleaning device, in particular to a rotatable rolling brush assembly and an automatic walking cleaning device used for a self-propelled cleaning device. Background technique [0002] In today's society, people spend a lot of time cleaning and cleaning the ground. Many families and companies have spent a lot of manpower and material resources. In order to solve the problem of floor cleaning, intelligent cleaning robots have emerged as the times require. The emergence of intelligent cleaning robots has greatly reduced manpower and material resources. It frees people from the tedious daily housework, so it is welcomed by consumers. During the working process, the sweeping robot usually does not need real-time control by the user. As it walks in the area to be cleaned, it can automatically absorb garbage including dust, debris, etc., and realize automatic cleaning. Therefore, the sweeping r...

Problems solved by technology

The disadvantage of this working method is that if the garbage particles are driven by the roller brush and thrown away, the garbage particles will not be successfully removed, thus reducing the cleaning efficiency

Although this working method avoids the shortcomings of the roller brush cleaning backwards, but the rotating speed of the roller brush is relatively high and there is no cover on the front side of the suction port. The roller brush sweeps forward and it is easy to push away the garbage, especially the garbage with large particles. At the same time, the dust swept up by the roller brush is not easy to enter the suction port, which affects the further removal of dust

However, if a baffle is installed on the front side of the suction port, it will hinder the garbage from entering the suction port, which will also affect the cleaning efficiency.
