[0002] Air purifiers can purify indoor air and filter out air impurities. They usually use a single filter element, which requires frequent replacement with long-term use. Disassembling and assembling air purifier filters is quite troublesome, and the filters cannot be recycled, which is a waste of resources.

[0003] Therefore, existing air purifiers need further improvement. Summary of the Invention

[0004] The purpose of this invention is to provide an air purifier with automatic filter cleaning, which can have multiple filters working alternately and can clean filters that have stopped working, thus enabling them to be used repeatedly.

[0005] To achieve the above objectives, the present invention adopts the following solution:
