Sterilization box based on plasma technology

Technical Field

The utility model relates to a sterilization device, in particular to a sterilization box based on a plasma technology.

Background

The sterilization refers to a measure that all microorganisms inside and outside any object can lose the growth and reproduction capacity forever by adopting strong physical and chemical factors.

The sterilization comprises a plurality of methods, wherein the plasma sterilization adopts a bipolar plasma electrostatic field to decompose and break negatively charged bacteria, polarize and adsorb dust, then combines components such as medicine-impregnated active carbon, an electrostatic net, a photocatalyst catalytic device and the like to carry out secondary sterilization and filtration, and a large amount of treated clean air rapidly flows in a circulating way, so that the controlled environment is kept in the standard of a sterile dust-free room.

Ozone sterilization is the sterilization of ozone by the oxidation of oxygen atoms to destroy the structure of the microbial membrane. The inactivation reaction of ozone to bacteria always proceeds very rapidly, unlike other bactericides: ozone can react with double bonds of bacterial cell wall lipids, penetrate into the interior of the thallus, act on proteins and lipopolysaccharides, and change the permeability of cells, thereby causing bacterial death. However, the prior art has the problem that ozone leaks to pollute the environment during ozone sterilization.

In order to improve the sterilization efficiency, plasma sterilization and ozone sterilization are often combined to sterilize materials to be sterilized, so that the sterilization efficiency is improved.

The circulating system is unbalanced, and the sterilization efficiency is not high.

For example, chinese patent CN111773427A discloses a plasma air disinfection treatment device, which comprises a housing, wherein the housing is provided with an air inlet and an air outlet, and a gas channel is formed in the housing, and a plasma generation assembly and a collection sterilization device are sequentially arranged along the gas channel from the air inlet to the air outlet; the air treatment device also comprises a control component, an electrical component and a fan component; the plasma generating assembly is a low-temperature plasma generating device; the collecting, sterilizing and disinfecting device is a back corona discharge device; the electrical assembly provides electrical energy to the air treatment device; the fan assembly provides power to guide air to enter from the air inlet and sequentially pass through the plasma generation assembly and the collection sterilization and disinfection device to the air outlet. The utility model is not sealed, and the condition that ozone leaks to pollute the environment can occur.

Therefore, how to design a sterilization box based on plasma technology, can accomplish that the sterilization is airtight annular, circulation system stable balance, it is a thing that awaits the solution to improve sterilization efficiency, has very important meaning.
