Description

Portable air sterilizer

Technical Field

The utility model relates to a portable air sterilizer which can continuously and actively sterilize and disinfect, has good sterilizing effect and is convenient to maintain, and belongs to the technical field of ultraviolet sterilization.

Background

Ultraviolet lamps have been used for many years for disinfection and their principle is that after ultraviolet light of a specific wavelength is used to irradiate cells, the DNA or RNA strands of the biological cells can be broken, and the biological cells can be killed permanently. The use of ultraviolet rays with proper intensity can kill biological cells within 1-2 seconds, thereby achieving the purpose of quick disinfection.

Ozone disinfection has also been known for many years and is based on the principle of ozone destruction of microbial membranes by oxidation with oxygen atoms to achieve bactericidal action. 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. Ozone also acts on nuclear substances in cells, such as purines and pyrimidines in nucleic acids, to destroy DNA. Ozone acts on cell membrane firstly, so that membrane components are damaged, metabolism is hindered, ozone continuously permeates through the membrane, lipoprotein and lipopolysaccharide in the membrane are damaged, permeability of cells is changed, and apoptosis is caused. Meanwhile, the ozone disinfection has the advantage that the ozone disinfection can float into corners with air, which cannot be irradiated by light.

However, both ultraviolet ray disinfection and ozone disinfection have the following disadvantages:

the ultraviolet ray sterilization has the disadvantage that the ultraviolet lamp can cause serious damage to human bodies due to the fact that light rays generated by the ultraviolet lamp directly irradiate the human bodies, and therefore when people move in the environment directly irradiated by the ultraviolet lamp, the ultraviolet lamp must be stopped from working, and the sterilization time efficiency is severely limited.

The limitation of ozone disinfection is that high concentration ozone is harmful to human body and people cannot stay in the ozone environment for a long time.
