Description

Portable breathing device capable of rapidly sterilizing air

Technical Field

The invention belongs to the technical field of portable breathing devices, and particularly relates to a portable breathing device for quickly disinfecting air and killing bacteria and viruses in the air based on UVC-LED.

Background

In the prior art, no matter what type of mask, the protection principle is isolation type blocking effect, filtration and prevention germ get into the respiratory tract of a user, the mask can not be reused, and a large amount of biological waste can be generated. The existing space disinfection ultraviolet device cannot be carried about, needs personnel isolation during disinfection, and has large disinfection space and long disinfection time.

According to different biological effects, ultraviolet rays are divided into four wave bands according to the wavelength, namely UVA wave band and wavelength of 320-400 nm; UVB wave band, wavelength 275-320 nm; UVC wave band, wavelength 200 ~ 275nm, UVD wave band, wavelength 100 ~ 200 nm. When ultraviolet rays irradiate pathogenic microorganisms, the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of the organism of the microorganisms is damaged, molecular chain breakage and cross-linking breakage of nucleic acid and protein are caused, and the normal replication function of the microorganisms is lost, which is a mechanism for inactivating the microorganisms. Generally, the UVC wave band is used for disinfection, and the wavelength of 254nm is most easily absorbed by DNA of organisms, so that the disinfection and sterilization effects are optimal. Ultraviolet sterilization belongs to a pure physical disinfection method, has broad spectrum and high efficiency and does not have secondary pollution. Ultraviolet disinfection is a widely used method, but most of the current methods are in the form of disinfection lamps which are hung in a certain space range to disinfect the surfaces of indoor articles with a large area.

Accordingly, there is a need to provide a portable breathing apparatus that can be reused, avoiding the production of large amounts of biological waste.
