Description

Technical Field

[0001] The utility model relates to the technical field of air treatment, in particular to an air purifier. Background Art

[0002] For families with pets, there will be a lot of pet hair indoors. If it is not cleaned up in time, it will be inhaled by the human body. Long-term inhalation of pet hair will have adverse effects on the human respiratory tract. In addition to manual collection and vacuuming, air purifiers can also be used to assist in cleaning pet hair.

[0003] Traditional air purifiers generally use pre-filters (such as filter screens) to filter out large particulate matter, pet hair, etc. After being used for a period of time, the pre-filter has too much attachment on its surface, which will affect the air intake of the air purifier. Therefore, the pre-filter needs to be manually removed to clean the attachment. The removal of the pre-filter is relatively cumbersome and the pre-filter of some air purifiers cannot be removed, resulting in low cleaning efficiency and poor cleaning effect. If equipped with an automatic scraping device, the production cost of the air purifier will increase and its service life will be shortened. Utility Model Content
