Description

An air filter with sterilizing function

technical field

The utility model relates to the technical field of air purification, in particular to an air filter which is mainly used indoors and has the function of sterilization and disinfection.

Background technique

In recent years, the air quality in major cities is not ideal, and there are many pollutants in the air. With the progress of the times and the improvement of living standards, in order to ensure the health and comfort of life, people often use various air purification equipment to clean indoor air. The air is purified. The filter is the main part of the filter to achieve its filtering and purification effect. The air filter is made of different materials. The materials include but are not limited to nylon, synthetic fiber, activated carbon, etc. The filter made of different materials are: Different use effects. At present, the air purification technologies commonly used in air purifiers include: filter adsorption technology, molecular complexation technology, photocatalyst: media technology, electrostatic dust collection technology, ozone technology, negative ion technology, etc.; material technologies mainly include : Photocatalyst, activated carbon, HEAP high-efficiency materials, negative ion generator, etc. Each technology has its advantages and disadvantages. For example, High-Efficiency Particulate Air, that is, high-efficiency air particulate filter, referred to as HEPA, HEPA is made of very fine organic fibers, which has a strong ability to capture particles and a small pore size. Large adsorption capacity, high purification efficiency, and water absorption. The purification rate for 0.3 micron particles is 99.97%. Therefore, there are many air purifiers using HEPA technology. However, if the air humidity rises in reality, many bacteria and viruses will be destroyed. The HEPA filter needs to be replaced after a period of use, but the replacement cost is relatively expensive; another example is the electrostatic dust removal technology is an air purification technology. Another new technology used in air purifiers, which was mainly used in the last dust removal process of power stations in the past, is now transplanted into air purifiers. The electrostatic precipitator can absorb fine dust as small as 0.1 micron, and the static electricity will release ozone. All the bacteria adsorbed by the precipitator are instantly killed by 6000V static electricity, but the electrostatic dust collection technology cannot filter harmful chemical pollutants such as benzene and formaldehyde. Another major defect is that ozone has certain hazards to human health, thus producing secondary pollution after purification.

Detailed ways

The specific embodiment of the utility model is described in detail below in conjunction with accompanying drawing of description:

As shown in Figure 1-3, a kind of air filter screen with sterilization function, described filter screen is assembled by the filter screen structure of three layers of different materials altogether, and each layer of filter screen structure is all formed by outer frame 4, filter The mesh surface 5 and the edge frame 6 are composed of a groove structure designed on the bottom edge of the outer frame 4, and the edge frame 6 can be embedded in the groove to achieve the assembly connection between the two filter mesh structures, and the filter mesh surface 5. After being installed inside the outer frame 4, the filter mesh surface 5 is closed and fixed inside the outer frame 4 with the edge-pressing surface frame 6; Nested inside to achieve sealing and fixing the filter mesh surface 5 inside the outer frame 4 .

The first filter layer 1 is composed of hair and salt evenly loaded on the filter cotton. The salt here is health-preserving coarse salt, granular crystal, and the main component is sodium chloride, which itself is a cheap Substances with sterilization and disinfection functions; this filter layer can effectively remove suspended solids or particles in the air, and salt has the function of disinfection, so the first layer of filtration will disinfect the air for the first time; the second The filter layer 2 is composed of cold catalyst and activated carbon uniformly loaded on the filter cotton. This filter layer can effectively remove irritating and toxic gases in the air, such as benzene, formaldehyde, and other harmful chemical pollutants; the third filter Layer 3 is composed of nano-silver ions uniformly adsorbed and loaded on the filter cotton. Due to the existence of nano-silver ions in this layer, nano-silver ions, as the latest generation of natural antibacterial agents, have the following characteristics: broad-spectrum antibacterial and bactericidal without any drug resistance Strong sterilization, can kill a variety of harmful bacteria in a few minutes; strong permeability, can quickly penetrate into the subcutaneous sterilization through the pores, and have good effect on infections caused by common bacteria, stubborn bacteria, drug-resistant bacteria and fungi Bactericidal effect; promote healing: improve the microstructure of the tissue around the wound, effectively activate and promote the growth of tissue cells, accelerate wound healing, reduce the formation of scars; antibacterial and durable, nano-silver particles are produced using patented technology, and there is a protective film on the outside , can be released gradually in the human body, so the antibacterial effect is long-lasting, so the filter layer of this layer can sterilize and disinfect the air that has undergone two layers of filtration again, and the continuous filtration of the three-layer filter layer not only filters and purifies the air, but also achieves the purpose of filtering The air in the air is sterilized and disinfected, which greatly improves the purification of the air. Because the safety of nano-silver ions is recognized by the international medical community, because trace silver elements are originally one of the important elements necessary for the human body, nano-silver ions have no charge. It will not combine with a variety of biologically active substances in the human body to deposit, absorb and kill bacteria in the pores, and will be completely discharged from the body without toxic and side effects.
