Description

The present invention relates to an air conditioner filter, and more particularly to an air conditioner composite filter which can significantly enhance the cleaning effect and is beneficial to the human body.

The problem of air quality deterioration is becoming more serious every day, and the air pollution in the indoor environment is far beyond the imagination of the general public. There are many pollutants in the air such as invisible pathogens, dust, oil smoke, dust, fumes, pesticides, pollen, harmful gases, etc. Besides pollution and odor, these harmful air pollutants are It promotes the production of free radicals and causes enormous harm to human health.

Free radicals are groups of atoms with unpaired electrons, and when an atom forms a molecule, the electrons in the chemical bond are paired so that the free radicals take away the electrons of other substances to form a stable compound. It is necessary, and this phenomenon is called oxidation in chemistry. Biological systems always encounter oxygen-free radicals such as superoxide anion radicals, hydroxyl radicals, fatty acid radicals, nitrogen dioxide, and nitric oxide. Reactive oxygen species and free radicals in living organisms have specific functions such as immunity and signal transduction, but excess of reactive oxygen species and free radicals causes destruction of normal cells and tissues of the human body and causes various diseases. In addition, more active oxygen and free radicals are generated from the human body due to sunlight radiation, air pollution, smoking, pesticides, etc. in the external environment, and nucleic acids in the living body are mutated, which is the root of human aging and diseases. It becomes. For example, cooking oil smoke contains free radicals, so housewives and restaurant cooks who are constantly working in the kitchen are much more likely to have lung disease or tumors than others. Become.

When it comes to automobiles, equipment and materials inside the vehicle emit toxic gases such as toluene, formaldehyde, ethanol, acetone, and butanol, but automobiles equipped with air conditioners have functions such as dust removal, sterilization, deodorization, and antifungal activity. By using the air conditioning filter together, it is possible to achieve air purification in the vehicle interior space and make the user feel healthier and more comfortable, and the free radicals formed in the vehicle interior environment threaten the user's health. There is also a method of removing free radicals by a method using fragrance or aroma oil.

On the other hand, air is one of the important mediators that cause diseases by invading the human body with pathogenic microorganisms that cause infectious diseases. The virus is transmitted mainly by droplets generated when coughing, squeezing or speaking, and by direct contact with the secretions of an infected person. Therefore, how to significantly enhance the effect of use by combining the function of preventing the transmission of the virus of the infectious disease with the air-conditioning filter has become a technical issue with practical value.

In view of the above problems, the main object of the present invention is to combine the first filter module and the second filter module side by side, without deteriorating the effect of air permeability, and to obtain a fine particulate matter of PМ2.5.

FIG. 3A is a locally enlarged cross-sectional view of the first filter module 110 of the air conditioning composite filter 100 according to the first embodiment of the present invention, and FIG. 3B is a locally enlarged cross-sectional view of the second filter module 120 of the same filter. A filter medium conforming to the HEPA standard is used for the first melt blown HEPA filter layer 112 and the second melt blown HEPA filter layer 122, the particle collection efficiency of the particulate matter having a particle size of 0.3 μm is 85% or more, and PM2. The particle collection efficiency of 5 (2.5 μm) fine particulate matter, mites (about 200 μm), and pollen (about 20 μm) reaches 99.9% or more. HEPA filter media are usually made from randomly oriented chemical fibers (eg polypropylene or polyester fibers) and glass fibers, and have a microscopic fluff structure that blocks large and small particulate matter. The higher the grade of the HEPA filter medium, the higher the particle collection efficiency, and the denser the pore arrangement of the fibers, the greater the resistance of the wind when taking in and purifying the wind, and the clean air supply rate (CADR: Clean Air). Delivery Rate) decreases. According to the grade of the HEPA filter medium adopted in the present invention, the condition that the other layers in the first filter module 110 and the second filter module 120 are combined with each other to meet the requirements of air permeability and particle collection efficiency. Under, the overall effect will be maximally balanced. In actual use, the appropriate grade can be selected according to the needs.

The silver nanoparticles of the above, for example, silver ions, nanozinc oxide, quaternary ammonium salts, etc. are mixed in, thereby enhancing the antibacterial and antifungal effect.

See FIGS. 3A and 4. FIG. 4 is a locally enlarged cross-sectional view of the polyphenol functional layer 114 in the first embodiment. The polyphenol functional layer 114 is composed of a natural polyphenol coating layer 115 formed of a natural polyphenol raw material bonded in the fiber structure of the polyphenol layer base fabric 116 (for example, a non-woven fabric) or on at least a part of the surface thereof to remove free radicals. The effect can reach 80% or more. Natural polyphenols can be selected from green tea polyphenol extracts, grape polyphenol extracts or mixtures of both. The natural polyphenol raw material itself is a liquid, and spray coating, immersion or transfer can be applied to the polyphenol layer base cloth 116.
