Efficient purification filter screen

Abstract

The invention provides an efficient purification filter screen which comprises a shell, a barrier salient arranged at the middle part of the inner wall of the shell and two filter screen components arranged on the two sides of the barrier salient respectively; each filter screen component is of a double layer structure and is composed of an activated carbon filter screen layer as an inner layer and a photocatalyst filter screen layer sleeving the outer part of the activated carbon filter screen layer; the barrier salient is two annular salients which are arranged in parallel; a catalyst unit filled with a molecular sieve catalyst is arranged between the two annular salients; connecting lugs are arranged on the outer surface of the shell. According to the efficient purification filter screen, air to be purified enters the filter screen structure, can be adsorbed, filtered and disinfected by the filter screen components firstly, then is catalytically disinfected by the catalyst unit and passes through a group of filter screen components again to be treated by secondary adsorption, filter and disinfection, thus the purification effect of the air is ensured with the purification action of an anode generator.

Description

technical field [0001] The invention belongs to the technical field of air purifier equipment, and in particular relates to a high-efficiency purification filter. Background technique [0002] At present, the problem of air pollution is becoming more and more prominent, and people's requirements and attention to the environment are getting higher and higher, so various air purification equipment have emerged as the times require. An air purifier is a small household appliance used to purify indoor air. It mainly solves the problem of indoor air pollution caused by decoration or other reasons. The filtering function of existing purifier equipment mainly depends on the filter screen set inside it. There are mainly laminated filter screens and activated carbon filter screens. The laminated filter screen is composed of multiple layers of filters with different effects. However, in the prior art, the structure of the filter screen is relatively complicated, and the assembly and m...

Problems solved by technology

An air purifier is a small household appliance used to purify indoor air. It mainly solves the problem of indoor air pollution caused by decoration or other reasons. The filtering function of existing purifier equipment mainly depends on the filter screen set inside it. There are mainly laminated filter screens and activated carbon filter screens. The laminated filter screen is composed of multiple layers of filters with different effects. However, in the prior art, the structure of the filter screen is relatively complicated, and the assembly and manufacture are troublesome. Purification function, can not actively carry out disinfection and sterilization, purification efficiency is not high

And the service life is short, it is more troublesome to replace
