Problems solved by technology

[0006] However, the existing filtering device has a single structure, which often cannot meet the requirements of filtering particulate matter and harmful chemical substances at the same time
[0007] Furthermore, due to the structural defects of existing filtering devices, in the prior art, taking the filter element of a vehicle-mounted air filter as an example, it only has a particle filter layer, so the antibacterial effect is relatively poor.
Moreover, due to the limitation of its structure, the filtering effect on PM 2.5 is poor, and can only reach about 45%.

Embodiment

[0040] see Figure 1 to Figure 2 , the present invention provides a multifunctional filter element 1, including a filter element body 11; the filter element body 11 includes a filter paper layer 111; layer 1113 and protective layer 1114 .

[0041] As mentioned above, it should be understood that natural plant polyphenols, plant tannins (Vegetable tannins), also known as plant polyphenols (Plant Polyphenols), are a class of polyphenolic compounds widely present in plants, and the content in vascular plants is only Next to cellulose, hemicellulose and lignin, it widely exists in the bark, root, leaf and fruit of plants, and its content can reach 20%. Plant tannins are secondary metabolites of plants and belong to natural organic compounds. That is, polyphenolic compounds refer to the general term of plant components with several phenolic hydroxyl groups in the molecular structure, including phenolic acids and flavonoids. Polyphenolic compounds have certain antioxidant capacit...

Abstract

The invention provides a multifunctional filter element which comprises a filter element body, wherein the filter element body comprises a filter paper layer; the filter paper layer comprises an antibacterial layer, a melt-blown electrostatic electret layer, an active carbon layer and a protection layer which are connected in sequence. Accordingly, the multifunctional filter element has an extremely good filter effect on ozone, nitric oxide, pollen, fungus and SO2 in outdoor pollution, dust mites, formaldehyde, methylbenzene and animal furs in indoor allergens or allergens from plants and the like, and can effectively purify air, improve the symptom of an allergic rhinitis patient and improve the air in a vehicle.

Description

technical field [0001] The invention relates to the technical field of air filtering equipment, and more specifically relates to a multifunctional filter element and a preparation method thereof. Background technique [0002] Air is one of the most precious resources in nature, but with the development of modern industry, urbanization, relative concentration of population and development of transportation, the atmosphere has been seriously polluted. [0003] With the continuous improvement of people's living standards, automobiles are gradually popularized in the domestic market. The increase in automobile exhaust and the increasingly severe environment make car owners pay more and more attention to the harm of PM2.5 fine particles to the human body. In addition, chemical substances released from car interiors, such as formaldehyde, benzene, TVOC, bromine, etc., are also permeated in the air; in addition, harmful substances volatilized by the air circulation in the air condi...
