Problems solved by technology

However, in the prior art, the roller brush only relies on the rotation of the motor to generate centrifugal force. In order to increase the centrifugal force, the rotation speed can only be increased. Although this improvement can improve the cleaning effect, the high rotation speed of the roller brush not only consumes a lot of energy, but also makes noise. Moreover, the wear of the rotating parts of the roller brush is serious, so the service life of the roller brush is short

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] The high pressure described below generally refers to higher than one standard atmospheric pressure, and the high-speed airflow described herein generally refers to the flow rate of air not equal to zero. Of course, in actual use, the pressure value of the high-pressure air is far greater than a standard atmospheric pressure, and the flow rate of the high-speed airflow is also far greater than zero.

[0033] The present invention provides a floor sweeping robot, which includes a casing 1, a dust collection chamber 2 is arranged inside the casing 1, a dust suction port 1.1 is provided at the bottom of the casing 1, and the dust suction port 1.1 and the dust collection chamber 2 Communication through the input channel 3, characterized in that it also includes a jet mechanism 4 for driving the air in the input channel 3 to flow into the dus...

Abstract

The invention discloses a rolling brush for a sweeping robot. The rolling brush comprises a rolling brush body, and is characterized in that a plurality of air holes are formed in the outer side wall of the rolling brush body, an air cavity is arranged in the rolling brush body, all the air holes communicate with the air cavity, and an air feeding channel communicating with the air cavity is arranged on at least end face of the rolling brush body. According to the rolling brush for the sweeping robot provided by the invention, a centrifugal force of the rolling brush can be improved without increasing a rotation speed of the rolling brush, and thus the rolling brush has good sweeping effect under same sizes and angular speeds.

Description

technical field [0001] The invention relates to the technical field of sweeping robots, in particular to a roller brush and a roller brush driving device for a sweeping robot. Background technique [0002] Traditional sweeping robots generally include two processes of sweeping and suction. The process of sweeping is to drive the debris particles to a suction port through the side brush, and then drive the debris through the synergy of the centrifugal force generated by the rotation of the roller brush and the suction force of the suction port. The dust particles are sucked into the dust collection chamber. However, in the prior art, the roller brush only relies on the rotation of the motor to generate centrifugal force. In order to increase the centrifugal force, the rotation speed can only be increased. Although this improvement can improve the cleaning effect, the high rotation speed of the roller brush not only consumes a lot of energy, but also makes noise. And serious ...
