Formaldehyde removal air purifier

Abstract

The invention relates to the technical field of formaldehyde purification equipment, in particular to a formaldehyde-removing air purifier, which is characterized in that air outside the formaldehyde air purifier is inside the formaldehyde air purifier by using a filter assembly positioned in a shell, particles such as pollen, hair and coarse dust are filtered firstly, and then particles such as fine dust are filtered; and finally, gaseous pollutants such as formaldehyde, benzene and TVOC are removed, so that layer-by-layer filtration of the formaldehyde air purifier is realized, on one hand, the saturation time of the formaldehyde filter screen is slowed down, on the other hand, the risk of secondary diffusion after formaldehyde adsorption is reduced, and meanwhile, through a replacement assembly mounted in the shell, the replacement efficiency is improved. On one hand, the saturated formaldehyde filter screen can automatically fall into the pull-out box body, the saturated formaldehyde filter screen can be conveniently treated through the pull-out box body, on the other hand, the formaldehyde filter screen can be automatically replaced, frequent replacement by personnel is not needed, and the trouble of personnel in use is reduced.

Description

technical field [0001] The invention relates to the technical field of formaldehyde purification equipment, in particular to a formaldehyde-removing air purifier. Background technique [0002] Formaldehyde air purifier, also known as "air purifier", formaldehyde air purifier is mainly composed of two parts: filter element and shell. , decomposition, transformation and other types of purification methods to isolate pollutants in the air such as dust, pollen, formaldehyde, etc. inside the purifier, and improve the air cleanliness of electrical products. [0003] However, in the existing formaldehyde air purifier, the adsorption capacity of the filter element is not unlimited in actual life, and there is a saturation upper limit, and there is still the risk of secondary diffusion of formaldehyde after adsorption, so for newly renovated houses, formaldehyde air The adsorption capacity of the purifier is very limited, so the formaldehyde air purifier used in the new house needs ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention: in the existing formaldehyde air purifier, the adsorption capacity of the filter element in real life is not infinite, but has a saturation upper limit, and there is still the risk of formaldehyde secondary diffusion after adsorption, so for new decoration For the house, the adsorption capacity of the formaldehyde air purifier is very limited, so the formaldehyde air purifier used in the new house needs to replace the filter screen in time, and the frequent replacement of the filter element will cause inconvenience to the personnel.
