Ozone generating-device

Technical field

The utility model belongs to electronics and air purifying process field, relates to a kind of ozone generating-device.

Background technology

In forest or by the waterfall, people have a kind of relaxed and joyful, tired cognition of losing, and its reason is exactly that the oxygen level of airborne ozone and negative ion is far above air indoor in the city.Along with the continuous aggravation of urban air pollution, people manage to build the various methodologies that produces ozone, negative ion by fair means or foul, to increase ozone and the content of negative ion in air ambient, reach pure and fresh and purpose that purify air.

The effect of ozone

The strong oxidizing property of ozone has four large functions: oxidation, sterilization, decolouring, taste removal.

Application of ozone mainly is sterilization, sterilization.This be because ozone extremely strong oxidation capacity is arranged, ozone under finite concentration can with the microorganisms biochemical reactions such as bacterium, virus, pathogenic agent.Ozone has very high energy, under normal temperature, normal pressure the microorganisms such as bacterium, virus, pathogenic agent is had stronger oxygenizement;

Ozone is wide spectrum, efficient quick sterilization agent, can kill rapidly various germs, virus, pathogenic agent and microorganism that humans and animals is caused a disease.Can destroy the biological structure of bacterium, virus and other microorganisms within a short period of time, the thorn breaking cell wall makes it to lose viability.After its concentration reaches certain value, sterilization and disinfection even can finish moment;

Ozone all will have greatly application as the sterilization means of excellent property in a lot of fields, be called as " green disinfectant ", and sterilization has clear and definite affirming to ozone sterilization in national technical standards such as " disinfection technology standards " in the Ministry of Health.Ozone is designated as important sterilizing air mode, once plays a part to be very large at sars period.

This ozone generating-device described in the utility model can be realized the purpose to air disinfection, sterilization after the ozone, the negative ion that discharge reach finite concentration.It is applicable to the less sealing of scope place sterilizing air and the purifications such as food processing shop, pharmacy, laboratory, sterilisable chamber, Operation theatre and family.This producer have circuit structure simple, use that components and parts are few, ozone output is large, the characteristics such as safe and reliable, long service life.

Below describe ozone generating-device described in the utility model related correlation technique content in implementation process in detail.
