AI Technical Summary

Technical Problem

In existing sweeping machines, the exhaust airflow cannot effectively flush the filter, causing the filter to become clogged and affecting cleaning performance.

Method used

A second air inlet and ventilation gap are set in the sweeper. The filter is automatically cleaned by the reverse airflow of the workstation. The suction of the workstation passes through the filter in reverse in the dust removal mode to wash away the attached dust.

Benefits of technology

It effectively removes accumulated dust from the dust collection chamber and dust from the filter elements, extending the service life of the filter elements and maintaining cleanliness.

Abstract

The second air inlet is formed in the filter box, and an airflow path under the two working modes of dust collection and dust discharge is provided, so that during dust discharge, suction force generated by the workstation can guide external air to enter from the second air inlet, reversely penetrate through the filter part and then enter the dust collection cavity. Reverse airflow generated by the workstation can effectively scour and strip fine dust attached to the side, facing the dust collecting cavity, of the filtering piece, and the dust is discharged to the workstation from the first air outlet along with the airflow. According to the dust collector, accumulated dust in the dust collection cavity can be removed, dust adsorbed on the filter part can be cleaned, the effective service life of the filter part is remarkably prolonged, and the cleaning performance of the filter part is kept.
