Abstract

This invention relates to the field of air purification equipment technology, specifically a self-cleaning air purifier with a dirt collection function, comprising: an intake mechanism, at least one set of filtration mechanisms, an air distribution mechanism, and a collection mechanism arranged sequentially from top to bottom; the filtration mechanism includes an upper air duct box and a lower air duct box, with a through groove between them for passing through strip filter media; a filter media roller is installed on the front side of the filtration mechanism, and a membrane-coated roller is installed on the rear side; the collection mechanism includes a collection roller driven by a drive motor; the strip filter media is led out from the filter media roller, passes through the through groove and guide roller group, and then winds onto the collection roller. This invention provides a self-cleaning air purifier with a dirt collection function, eliminating the need for manual filter cleaning, automatically updating the filter media and collecting dirt, achieving high purification efficiency, convenient maintenance, and suitability for various usage environments.
