AI Technical Summary

Technical Problem

Dirt residues in the suction pipes of cleaning equipment lead to bacterial growth and odor generation, affecting user experience and possibly causing blockages.

Method used

By controlling the suction device to operate alternately at different power states, negative pressure suction fluctuations are generated to achieve self-cleaning of the sewage suction pipe. Combined with the rotation of the roller brush device and the flushing of the cleaning liquid, the cleaning liquid forms a surge in the pipe for flushing.

Benefits of technology

Effectively remove dirt from the suction pipe, prevent bacterial growth and odor, reduce blockage, improve user experience and extend equipment life.

Abstract

The invention provides a self-cleaning method of cleaning equipment and the cleaning equipment. The self-cleaning method of the cleaning equipment comprises the steps that a suction device of the cleaning equipment is controlled to operate for t1 time at first power P1, so that the suction device is in a first state; and the suction device is controlled to continue for t2 in the state that the operation power is smaller than the first power P1, and t2 is smaller than t1, so that the suction device is in the second state. The first power P1 is larger than zero and does not exceed the dirt suction power P0 of the suction device. According to the self-cleaning method provided by the invention, the dirt suction pipeline of the cleaning equipment can be self-cleaned, so that the use experience of a user is improved.
