Problems solved by technology

Air purifiers use adsorption, decomposition, etc. to eliminate harmful gases in the air and remove various odors. They are roughly divided into three categories. One is purified industrial raw materials such as activated carbon as raw materials, which can eliminate odors. Long-lasting, secondary treatment is required, and the antibacterial performance is poor; one type is fragrance as a raw material, which can only cover the odor with fragrance, and cannot be eradicated; High security, but low processing efficiency and long time
The photocatalyst air purifier with titanium dioxide as raw material not only has a certain effect on harmful odor gases such as formaldehyde, ammonia, sulfur, benzene, etc., but also has a good antibacterial effect; but the current titanium dioxide air purifier also has a short-lasting effect. Therefore, it is meaningful to develop a purifying agent with excellent antibacterial performance and air purification performance.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purifier. Background technique [0002] The temperature and humidity of the indoor environment are suitable, and it is easy to breed harmful microorganisms. Moreover, there are a large amount of harmful gases such as formaldehyde after new furniture and decoration, which seriously threaten human health. It is very necessary to purify the indoor air regularly. Air purifiers use adsorption, decomposition, etc. to eliminate harmful gases in the air and remove various odors. They are roughly divided into three categories. One is purified industrial raw materials such as activated carbon as raw materials, which can eliminate odors. Long-lasting, secondary treatment is required, and the antibacterial performance is poor; one type is fragrance as a raw material, which can only cover the odor with fragrance, and cannot be eradicated; The security is high, but the process...
