Multipurpose anti-dust gauze mask provided with airtight outer layer, formed with gaps in middle and conducting air exchange at sides

Abstract

The utility model relates to a novel multi-purpose dust-proof mask with an airtight outer layer and a gap in the middle to ventilate on the side. Due to the holes in the outer layer and the large exposed area of ​​the traditional dust masks on the market, the holes are easily blocked or directly penetrated by dust, smog particles, droplets, etc. that come into contact with the front, and they cannot prevent water vapor or spray liquid. It is applicable to various climates and places at the same time, and has poor versatility. The outer fabric of this new dustproof mask is made of airtight material. A gap is formed by placing a bracket between the outer fabric and the inner fabric. The gap leads to the outer edge of the mask for breathing and ventilation. Since the outer layer is airtight, It can effectively solve the above shortcomings of traditional dust masks, and can effectively prevent wind, cold, dust, droplets, haze, gas, and spray liquid. It can be used in medical, civil, industrial and special places, and can be used in various Use under climatic and environmental conditions.

Description

Technical field [0001] The invention relates to a novel mask, especially capable of preventing wind, cold, dust, droplets, smog, water vapor and spray liquid, and can be used in medical, civil, industrial and special places. Background technique [0002] At present, there are various forms of dust masks on the market. According to the shape, there are cup type, cover type and flat type. The combination of cloth and cotton, or adding a breathing valve or adding a filter to achieve certain specific functions, one is to use an airtight plastic cover on the outer layer, and achieve certain specific functions by adding a breathing valve and a complex filtering system. Function, the masks or masks made by the above methods are either ineffective, or too complicated, expensive and not applicable. Traditional dust masks on the market have holes in the outer layer and a large exposed area. It is easy to be blocked or directly penetrated by dust, smog particles, droplets, etc. that c...

[0002] At present, there are various forms of dust masks on the market. According to the shape, there are cup type, cover type and flat type. The combination of cloth and cotton, or adding a breathing valve or adding a filter to achieve certain specific functions, one is to use an airtight plastic cover on the outer layer, and achieve certain specific functions by adding a breathing valve and a complex filtering system. Function, the masks or masks made by the above methods are either ineffective, or too complicated, expensive and not applicable. Traditional dust masks on the market have holes in the outer layer and a large exposed area. It is easy to be blocked or directly penetrated by dust, smog particles, droplets, etc. in frontal contact, and it cannot prevent water vapor or spray liquid. It cannot be applied to various climates and places at the same time, and has poor versatility.
