Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an air purifier filter screen capable of improving the efficiency of purifying chemical pollution. Background Art

[0002] With the improvement of living standards, more and more people are beginning to pay attention to indoor air quality and strive to improve it, because studies have shown that the level of indoor pollution is much greater than that of outdoor air, especially decoration pollution and pollution from interior decorations, which cause serious harm to human health. Newly renovated houses mainly contain formaldehyde, TVOC, benzene, xylene and other harmful gases. These harmful substances are highly irritating and toxic, and will seriously endanger our health.

[0003] At present, the methods to solve indoor pollution mainly include ventilation, air purifiers, and air purification products. Among them, ventilation takes a lot of time and is slow to take effect. There are a wide variety of air purification products on the market, but the effect is minimal. The use of air purifiers is currently the most widely used and fastest-acting method for removing formaldehyde. The formaldehyde removal technology in air purifiers on the market mainly relies on the physical adsorption of activated carbon to remove formaldehyde. The disadvantage is that the physical adsorption effect is greatly affected by the carbon content, and the activated carbon content in the purifier is low, which limits the contact area between the activated carbon and formaldehyde and makes it easy to saturate, resulting in unsatisfactory formaldehyde removal effect.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an air purifier filter that can improve the efficiency of purifying chemical pollution is proposed. Utility Model Content

[0005] The purpose of the present utility model is to provide an air purifier filter that can improve the efficiency of purifying chemical pollution, so as to solve the problems raised in the above background technology.

[0007] Furthermore, a mounting cavity with front and rear ends opened is provided inside the supporting frame, and screw holes are provided around the openings at both ends of the mounting cavity.

[0008] Furthermore, the screw holes are fastened with metal protective mesh covers by screws, and the metal protective mesh covers are composed of interwoven metal grids and cover the openings at both ends of the installation cavity.

[0009] Furthermore, ear plates are integrally fixed on both sides of the top of the filter metal frame, and the ear plates are fixed to the ear grooves on both sides of the slot opening by screws, and a handle is integrally fixed on the middle end of the top of the filter metal frame.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. When the utility model is in use, the HEPA filter of the present application is composed of a stack of sub-glass fiber membranes folded back and forth continuously to form a wavy gasket for placing and supporting the filter medium, and a catalytic agent layer is coated on the surface of the HEPA filter. The catalytic agent layer is mixed with isocyanate, citric acid, potassium persulfate, Bordeaux mixture, sodium chlorite, aluminum oxide, magnesium oxide, sodium hydroxide and water, stirred evenly, and the catalytic agent layer with a paste is filtered out through precipitation. The air purification filter prepared by the present application does not rely on the traditional fiber material to intercept PM2.5 and other substances directly, but relies on the Thousands of small molecular sieve particles are used for adsorption. Pollutants will be adsorbed from any direction they pass through. Molecular pollutants will be decomposed by the subsequent pharmaceutical layer instead of being retained on the surface of the filter, thereby affecting its service life and adsorption effect. The air purification filter of this application has a long service life and can not only remove PM10, PM2.5 and formaldehyde, but also has good sterilization, odor removal and TVOC removal effects. Moreover, the production cost of the filter is relatively low. As the primary filter of the air purifier, it can extend the service life of the filter element and greatly reduce the cost of replacing the air purifier filter element.

[0012] 2. When the present invention is in use, the filter metal frame loaded with the HEPA filter is inserted into the corresponding slot opened at the top of the supporting frame. The corresponding ribs on the inner walls on both sides of the installation cavity provide a guide for the insertion of the filter metal frame, and the positioning magnets arranged on the opposite sides of the bottom of the slot are positioned by magnetic adsorption with the filter metal frame. Then, the ear plates on both sides of the top of the filter metal frame are fixed to the ear grooves on both sides of the slot opening by screws, so as to further improve the stability of the installation of the filter metal frame. The screw holes around the front and rear openings of the supporting frame are fixed with metal protective mesh covers by screws, which can block larger impurities such as lint, and the handle at the middle end of the top of the filter metal frame is convenient for users to extract and replace it from the corresponding slot, which is more practical.
