Air purification device

Abstract

The invention provides an air purification device which comprises a shell and an electric control assembly. A fan is arranged at an air inlet and / or air outlet of the shell. The air purification device further comprises a first accelerant filter screen, a disinfection assembly and a second accelerant filter screen, all of which are sequentially arranged in the shell. The disinfection assembly comprises a mounting plate, an ultraviolet lamp, a high-frequency wave generator and a magnet, wherein the ultraviolet lamp, the high-frequency wave generator and the magnet are arranged on the mounting plate. The first accelerant filter screen and the second accelerant filter screen are arranged on the two sides of the disinfection assembly, and secondary purification to harmful substances is achieved. Under the irradiation action of ultraviolet light emitted by the ultraviolet lamp, after accelerants on the first accelerant filter screen and the second accelerant filter screen absorb wave energyof light waves, oxygen and water in air are converted into high oxidative activity active groups, and therefore organic pollutants are subjected to oxygenolysis, non-toxic water and carbon dioxide are generated, and sterilization and disinfection are achieved. Meanwhile, under the action of the wave energy of high-frequency waves generated by the high-frequency wave generator and a magnetic fieldgenerated by the magnet, the catalytic degradation reaction is further promoted, and the purification efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of air purification equipment, in particular to an air purification device. Background technique [0002] Air purifiers are products that can absorb, decompose or transform various air pollutants and effectively improve air cleanliness. They can be used in homes, shopping malls, office buildings and other places. Most of the existing air purifiers are catalytic purifiers. Photocatalyst is a material with catalytic function. Under certain conditions, its catalytic function is particularly obvious, producing a strong catalytic degradation function and effectively decomposing harmful substances in the air (such as formaldehyde, germs, etc.). The common method of use is to irradiate the photocatalyst coated on the surface with ultraviolet light. This method requires long enough contact time of air, ultraviolet light and photocatalyst to obtain effective sterilization and disinfection effect, so its actual purification ef...
