Technical Field

[0001] The utility model relates to the technical field of household disinfection machines, in particular to a household plasma disinfection machine. Background Art

[0002] With the gradual pollution of the natural environment and the occurrence of public health incidents, people pay more and more attention to disinfection in daily life. Plasma disinfection machine is based on plasma technology. It achieves the purpose of disinfection by converting gas molecules into plasma state. The active particles and free radicals it produces have strong physical and chemical attack effects on microorganisms. At the same time, plasma can also react chemically with organic volatiles and harmful gases in the air, converting them into harmless or low-toxic substances, thereby achieving comprehensive purification of the air.

[0003] However, it is inevitable that plasma disinfection machines generally use high-frequency voltage or dielectric barrier discharge to ionize the molecules in the gas flowing through the equipment, generating a large number of positive ions, negative ions, electrons and reactive oxygen species, among which the generation of ozone is inevitable. Ozone has strong oxidizing and bactericidal effects, and can effectively kill bacteria, viruses and other microorganisms in the air, but it is harmful to the human body at high concentrations, and may cause respiratory irritation, conjunctival irritation and other problems. Long-term or excessive contact may also have adverse effects on human health. Therefore, the existing technology generally reduces the working time or working power of the plasma disinfection machine to control the generation of ozone, resulting in poor disinfection effect of the existing plasma disinfection machine, and still has an impact on people, especially infants and young children.
