Description

Novel anti-virus mask

Technical Field

The invention relates to the field of medical and sanitary equipment in time, in particular to a novel anti-virus mask.

Background

The biological aerosol refers to bacteria, viruses, fungi, chemical toxins and the like suspended in the air and is an important component of atmospheric particulates. The epidemiological significance of this is that a susceptible person may become infected by inhalation of airborne virus-containing aerosol particles suspended in the air without encountering the affected person. Aerosol propagation has exceeded the velocity of spray and contact propagation. Most aerosols are invisible to the naked eye, such as PM2.5 aerosols with the particle size of less than 2.5 microns, viruses cannot survive alone when leaving a host, after infected people leave a human body, such as droplets containing new coronavirus or breath, water in dry air is evaporated rapidly, cells and viruses are inactivated due to water shortage, and the cells and the viruses are easily killed thoroughly when encountering sunlight ultraviolet rays or ozone, acid gas and the like in the air. And in haze weather humidity is big, the virus more likely combines with haze droplet granule, just can survive longer and disperse in the haze granule.

Most masks in the market at present adsorb tiny particles through static electricity, but the static electricity disappears due to the breathing water vapor, and the adsorption effect is obviously reduced after the masks are worn for one hour, so that the adsorption is ineffective.

Disclosure of Invention

In order to solve the problems in the prior art, the invention provides a novel anti-virus mask, which comprises the following specific technical scheme:

the utility model provides a novel anti-virus mask, includes the gauze mask area and the cover body, the cover body from outer to interior one-level filter fiber, scribble graphite alkene complex filter fiber layer, zone of heating, traditional chinese medicine complex filling layer and inside filter layer of including in proper order, gauze mask area and cover body integrated into one piece, the zone of heating be provided with the jack, can be connected with the power, heat the disinfection to the cover body.

Furthermore, the heating layer is a waterproof resistance wire net, the shape and the area of the waterproof resistance wire net are the same as those of the mask body, after the mask is used, the mask is taken off, a power supply is plugged, and the mask can be heated, so that viruses and bacteria are eliminated and abraded.

Furthermore, the nano-scale traditional Chinese medicine particles are filled in the traditional Chinese medicine compound filling layer, so that various bacteria and viruses can be killed.

Further, the inside filter layer be by two-layer constitution, including the moisture absorption membrane of outer waterproof ventilated membrane and inlayer, the steam of damming in the gauze mask is adsorbed by the moisture absorption membrane, can be with the evaporation of steam on the moisture absorption membrane, resume dry state to the in-process that heats the gauze mask.

Further, the cover body is fixed through a sealing clamp, gaps are reserved between every two layers, and every layer can be replaced.

Furthermore, the primary filter fiber and the filter fiber layer coated with the graphene compound are both prepared by an electrostatic spinning technology, are both made of flame-retardant materials, and have the advantages of high specific surface area, strong adsorption capacity, small pore diameter, high barrier capability, light weight, good air permeability and the like. When the mouth mask is electrically heated, the mouth mask can not be burnt due to overhigh temperature.

The invention has the beneficial effects that: the mask is provided with the resistance wire mesh, so that the mask is better in support, a larger space can be reserved for breathing, the breathing is smoother, the mask is also provided with the traditional Chinese medicine layer and the filter layer coated with the graphene compound, pathogenic microorganisms in air can be well filtered, and the graphene compound solution is sprayed on the filter screen, so that dust and PM2.5 in (dry and wet) air can be effectively removed. The graphene-based mask can directly adsorb micro particles by means of the advantage of the ultra-large specific surface area of graphene, the problem of failure caused by water vapor does not exist, and the high-efficiency adsorption rate can be kept for a long time. The mask can be connected with a portable power supply to sterilize the mask at any time.

The invention can effectively prevent bacteria and viruses from entering the respiratory system of people in an aerosol mode, can be repeatedly used and is economical. The interval space between every layer of this gauze mask is big, and the structure is three-dimensional to the gas permeability is better.
