an air purifier

Abstract

The invention discloses an air purifier which comprises a dedusting component and a formaldehyde removal component, wherein the dedusting component comprises a lower shell, an air inlet fan arranged at the bottom of the lower shell, and a dust collecting box arranged at the inner bottom of the lower shell and having an opening; a plurality of plastic dust collection discs and fiber dust collection discs are piled up in the dust collecting box; the plastic dust collection discs and the fiber dust collection discs are arranged alternatively, and a plurality of air guide holes are formed in the plastic dust collection discs and the fiber dust collection discs; the formaldehyde removal component comprises an upper shell communicating with the lower shell and a flow guide fan arranged at the bottom of the upper shell; and the upper shell is internally provided with an ultraviolet lamp and at least one photocatalyst coating disc. The air purifier has the following benefits: static electricity generated by friction of two materials is used for adsorbing dust so as to purify air; the air purifier can be repeatedly used; and since electrostatic dust collection using high voltage ionization is not adopted, danger and power consumption are greatly reduced, and secondary pollution of indoor environment caused by generation of ozone can be avoided.

Description

technical field [0001] The invention relates to an air purifier. Background technique [0002] At present, there are two main sources of pollution to household air: dust (including fine dust, PM2.5, etc.) and formaldehyde. There are various types of air purifiers on the market for removing dust and formaldehyde, but they all have the following problems: 1. High polymer and activated carbon are required as filters, which cannot be reused and are expensive; 2. Use high-voltage ionized electrostatic vacuum cleaners , greatly reducing the risk and power consumption, and will generate ozone to cause secondary pollution to the indoor environment. Contents of the invention [0003] The problem to be solved by the present invention is to provide an air purifier which utilizes two kinds of materials to generate static electricity to absorb dust to purify the air. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a...
