Respirator

Abstract

The invention provides a respirator. The respirator comprises nanometer antibacterial layers made from a nanometer antibacterial material, and further comprises a nanometer electricity generation unit. The nanometer electricity generation unit is connected with the nanometer antibacterial layers and used for generating charges to form an electric field on the nanometer antibacterial layers. Due to the fact that the respirator provided by the invention further comprises the nanometer electricity generation unit, the nanometer electricity generation unit can be used for energy supply, an external power source is not needed, and current generated by the nanometer electricity generation unit can form the electric field with intense changes in the nanometer antibacterial layer; on the one hand, the dissolving effect of the nanometer antibacterial material is improved, and the bactericidal effect is better; and on the other hand, under the action of electrostatic adsorption of the electric field, the contact probability of the antibacterial material and bacteria is increased, the bactericidal effect is remarkable, meanwhile, electroporation of the bacteria can be achieved, and the bactericidal effect is further improved.

Description

Technical field [0001] The present invention relates to the field of medical protective articles, in particular to a mask. Background technique [0002] Due to the increasingly serious environmental pollution problem, people are paying more and more attention to personal protection against bacteria, viruses, pollutants, etc. Only filtering bacteria or pollutants through filtration is far from meeting people's protection needs. In the prior art, there has been a germicidal mask that kills bacteria by adding a germicidal and antiviral agent on the surface of the mask. [0003] However, this kind of mask needs to have a certain timeliness. As the bactericidal antiviral agent volatilizes, its antibacterial effect will be greatly reduced, and the bactericidal antiviral agent may cause adverse effects on the human body (such as allergies and other symptoms). Its biological safety remains to be Discuss. That is, there is a lack of a mask that has a significant sterilization effect and i...
