Description

Technical Field

[0001] The present application relates to the field of vacuum cleaners, and more specifically, to a dust cleaning structure for vacuum cleaners. Background Art

[0002] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structure. The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generate negative air pressure in the sealed shell, and suck in dust, dirt and air from the dust suction part; the dust and dirt are collected through the filtration system, and the air is discharged by the fan.

[0003] Some existing vacuum cleaners have cyclone separation chamber structures for separation and filtration. A lot of dust and dirt accumulate on the filter screen of the separation structure. If it is not cleaned for a long time, it is easy to cause the filter screen to be blocked and the dust suction wind force to decrease.
