ONE TYPE OF WALL-MOUNTED AIR PURIFIER

[0001] The present utility mode relates to an air purifier, in particular to an air purifier for hanging directly on a wall.

[0002] At present, most known indoor air purifiers have a tabletop or standing structure, and must be arranged on a table or floor during use. However, large amounts of dust in indoor air, including partly respirable particles (commonly called PM10) and very fine particulates (commonly called PM2.5), are suspended in high-level air indoors due to the effect of buoyancy. Respirable particles and very fine particulates are collectively referred to as particulates, a term which can be abbreviated as dust. The purifying effect of conventional tabletop or standing air purifiers on such dust is limited. Moreover, conventional tabletop or standing air purifiers must be arranged on a table or floor, taking up usable indoor space, and causing great inconvenience.
