Description

Skirt edge assembly and cleaning equipment thereof

Technical Field

The utility model relates to a cleaning device technical field, concretely relates to shirt rim subassembly and cleaning device thereof.

Background

Among the cleaning devices, hand-held cleaning devices are often used for home cleaning of users. During use of the cleaning appliance, the dirt cup tends to act as an outer wall of the cyclonic separation unit to separate dirt, and the space between the dirt cup and the cyclonic separation unit acts as a separation chamber. The separation chamber includes a cyclonic separation section at one end of the dirt cup and a dirt collection section at the other end of the dirt cup. Where dirt is separated by an airflow flowing around the separation chamber. The separated clean air passes through a filter screen of the cyclone separation unit for next separation.
