AI Technical Summary

Technical Problem

Cleaning equipment has low dust removal efficiency on soft surfaces such as carpets. The existing roller brush assembly design results in insufficient airflow velocity and vacuum, making it difficult to effectively suck up dust particles.

Method used

Design a roller brush module, including a shielding component and a drive mechanism. The shielding component moves up and down under the action of friction to adjust the size of the suction port, adapting to hard and soft surfaces to be cleaned, enhancing airflow speed and vacuum, and improving dust collection efficiency.

Benefits of technology

Without increasing suction power, it significantly improves the dust removal efficiency and effectiveness on soft surfaces to be cleaned, ensuring that dust particles are efficiently drawn into the dust box.

Abstract

The utility model discloses a rolling brush module and cleaning equipment, the rolling brush module comprises a rolling brush main body and a shielding assembly, the rolling brush main body is at least used for being installed at the bottom of the cleaning equipment, a suction port is formed between the rolling brush main body and a to-be-cleaned surface along a first direction, and the suction port is used for sucking garbage on the to-be-cleaned surface into a dust box of the cleaning equipment; the shielding assembly comprises a shielding piece and a driving mechanism, the shielding piece is at least arranged on the front side of the rolling brush body in the advancing direction of the cleaning equipment, and the driving mechanism is connected with the shielding piece and configured to shield the rolling brush body under the action of friction force applied by the to-be-cleaned face. And the shielding piece is driven to do lifting motion relative to the rolling brush main body so as to change the size of the suction port. The dust removal device solves the problem that the dust removal efficiency of the cleaning device on the soft to-be-cleaned surface is low.
