Multi-layer filtering antibacterial protective mask

Abstract

The invention discloses a multi-layer filtering antibacterial protective mask, and the mask comprises a sterilization layer, a protective melt-blown layer attached to the sterilization layer and a skin-friendly layer attached to the protective melt-blown layer, wherein the sterilization layer is a silver fiber layer, the skin-friendly layer is a silver fiber non-woven fabric and an anti-fog layer,and the anti-fog layer comprises a first anti-fog area and a second anti-fog area; the first anti-fog area and the second anti-fog area are located in the skin-friendly layer and are symmetrically arranged relative to the nose wings, gas collecting pieces are placed in the first anti-fog area and the second anti-fog area respectively, inlet and outlet holes are formed in the opposite ends of thefirst anti-fog area and the second anti-fog area, and the inlet and outlet holes are used for conveniently taking the gas collecting pieces. According to the invention, efficient sterilization is realized, the antibacterial effect can reach 99%, breathing is smooth, non-oily particles can be filtered, and repeated washing can be carried out.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a multi-layer filter antibacterial protective mask. Background technique [0002] KN95 masks can be used to prevent new coronavirus infection. KN95 masks have passed the national standard 2626-2006 respiratory protective equipment, and are self-concerned anti-particulate absorber standards certified masks. For non-oily particles, the protection efficiency of small sodium chloride particles used in general experiments is not less than 95%, and more than 95% of the particles can be blocked outside the mask. [0003] Influenza is caused by influenza virus, which belongs to the family Enmyxoviridae and is an RNA virus. There are three types of influenza viruses: influenza A virus, influenza B virus and influenza C virus. Among them, influenza A virus is the most likely to mutate and can infect humans and various animals. It is the main pathogen of human influenza and often causes pand...
