LED ultraviolet self-disinfection mask

Abstract

The invention discloses an LED ultraviolet self-disinfection mask. The mask comprises a mask body covering the outer side of the mouth and the nose of a human body, and a fixing part connected with the left side and the right side of the mask body. The mask body comprises a filter body and a shell on the periphery of the filter body. The filter body comprises an annular support, an annular lamp panel is arranged on the inner wall of the support, a deep ultraviolet LED is arranged on the lamp panel, and a nano photocatalytic filter screen is fixed to the inner side of the support. An air inletand outlet is formed in the front side of the shell, a main board is arranged in the shell, the main board is electrically connected with the lamp panel, and the shell protrudes forwards so that a cavity can be defined by the shell, the nano photocatalytic filter screen and the human face. Bacteria are killed through photocatalysis of the deep ultraviolet LED, filtration and sterilization are conducted through the silver ion filter screen, and adsorption and sterilization are conducted through activated carbon, so that viruses are killed more thoroughly, air entering a human body and air exhaled by the human body can be fully purified, air flowing in two directions is disinfected air, and cross infection of respiratory diseases is avoided.

Description

technical field [0001] The invention relates to the technical field of sanitary protective articles, in particular to an LED ultraviolet self-disinfecting mask. Background technique [0002] With the rapid development of industry, the amount of smoke and dust emissions has increased, and haze weather has become a major problem that plagues people. While filtering smoke and dust, the application of masks has become a major solution for people. Wearing a mask can not only block part of the smoke and dust, but also has the effect of decoration and beauty. [0003] However, the filtering effect of traditional masks is not good, and the blocking effect of PM2.5 is poor; there are also some masks with better blocking effect that have poor ventilation effect, and fans are equipped on the masks for intelligent air circulation. But this undoubtedly increases the volume of the mask, which makes it very inconvenient to carry. At the same time, it increases the production cost of the ...

AI Technical Summary

Problems solved by technology

[0003] However, the filtering effect of traditional masks is not good, and the blocking effect of PM2.5 is poor; there are also some masks with better blocking effect that have poor ventilation effect, and then a fan is equipped on the mask for intelligent air circulation

But this undoubtedly increases the volume of the mask, which makes it very inconvenient to carry, and at the same time increases the production cost of the product, and the roar of the fan can also cause discomfort to the human body

[0004] In addition, the existing masks can only achieve one-way dust isolation. The air exhaled by some sick people (such as patients with colds and coughs) carries more germs, which cannot be fully isolated and sterilized, and it is easy to communicate with the surrounding people. Form cross-infection, poor practicability
