AI Technical Summary
In existing filter-type air purifiers, the pre-filter tends to accumulate dust, hair, and other pollutants after prolonged use, resulting in poor cleaning performance, reduced air purification efficiency, and shorter lifespan.
A filter cleaning device is designed, including a rotating component and a cleaning mechanism. The primary filter is rotated by a roller brush component, and the first scraper component and the second scraper component are combined to scrape off the contaminants, which are then collected in a dust collection box to prevent the contaminants from re-adhering.
It effectively removes contaminants from the surface of the pre-filter, reduces contaminant entanglement, improves cleaning effect, extends filter life, and enhances air purification efficiency.
