Description

Technical Field

[0001] The utility model relates to the technical field of air purification equipment, in particular to a plasma air disinfector. Background Art

[0002] As people's awareness of hygiene increases, and with the impact of infectious diseases such as epidemics, people's requirements for disinfection equipment are gradually increasing. Therefore, various types of plasma air disinfectors have appeared on the market to ensure people's health and safety.

[0003] Currently, there are mainly UV air disinfectors, air purifier air disinfectors and plasma air disinfectors on the market. UV air disinfectors mainly use ultraviolet rays to irradiate bacteria, viruses and various microorganisms, thereby destroying their genetic structure to achieve the purpose of sterilization; air purifier air disinfectors mainly filter various bacteria, microorganisms and other substances through their main component, the anion filter, which is a low-cost implementation solution on the market; plasma air disinfectors mainly produce high-concentration plasma (positive and negative ions, OH hydroxyl groups, free electrons, etc.) with high-activity bactericidal factors. These highly active plasma components undergo oxidation reactions with proteins and nucleic acids in bacteria and denature them, killing various microorganisms. At the same time, the high-energy electrical energy released by the annihilation of these high-kinetic energy electrons and ions acts on the bacterial cells, producing a breakdown etching effect that stops the bacterial metabolism, thereby achieving the purpose of disinfection and sterilization.

[0004] However, the lamps of ultraviolet air disinfectors are easily damaged and require high replacement frequency (the life of ultraviolet lamps is generally 800-1200 hours), and the activated carbon filter needs to be replaced at fixed times, otherwise it is easy to cause poisoning; the filters of air purifier-type air disinfectors have the problem of incomplete filtering of bacteria and microorganisms, and residual viruses, bacteria and various microorganisms can easily cause cross-infection; existing plasma air disinfectors have low power, complex structure, and the positive and negative ions they produce are unstable. They have achieved effective sterilization to a certain extent, but they have fewer plasma modules, a smaller disinfection area, and the size of the purified particles and aerosols is limited.
