Problems solved by technology

However, traditional masks are usually made of overlapping layers of gauze or non-woven fabrics. When used, the masks cover the mouth and nose. In order to filter tiny particles in the air, or when the dust in the air is very high, it is necessary to increase The number of layers of gauze or non-woven fabric, or increasing the textile density of gauze or non-woven fabric, will reduce the breathability of the mask. When used, it will make it more difficult for people to breathe and feel stuffy, and at the same time, the exhaled moisture cannot be discharged. , making people feel very uncomfortable

Abstract

The invention discloses a PM2.5-preventing active carbon mask. The PM2.5-preventing active carbon mask comprises a filter plate, an ear hang strap positioned on the left side of the filter plate, andan ear hang strap positioned on the right side of the filter plate, wherein the filter plate comprises a first non-woven fabric, filter paper, an active carbon non-woven fabric and a second non-wovenfabric in the sequence from inside to outside. The PM2.5-preventing active carbon mask provided by the invention is good in breathability, is portable and comfortable, and is sanitary and environmentally friendly, and the contained active carbon non-woven fabric layer can realize multi-effect isolation for the hazardous substances including PM2.5, dust particles, sulfides, nitrides, organic hydrocarbon compounds, metal ions, bacteria, viruses and the like in the environment, can eliminate hazardous substances, and can provide clean and safe air for the human body.

Description

technical field [0001] The invention relates to an anti-PM2.5 mask, in particular to an anti-PM2.5 activated carbon mask. Background technique [0002] A mask is worn on the mouth and nose to filter the air in the mouth and nose, so as to block harmful gases, odors, and droplets from entering and leaving the wearer's mouth and nose. It is mostly made of cloth or paper. PM2.5 is inhalable particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere. PM2.5 contains harmful gases and heavy metals. PM2.5 is small and light, and it is difficult to naturally settle to the ground. It floats in the air for a long time and is It absorbs a large amount of toxic and harmful substances, which is very harmful to human health. Developing a mask that can effectively block PM2.5 has become a top priority. However, traditional masks are usually made of overlapping layers of gauze or non-woven fabrics. When used, the masks cover the mouth and nose. In order to filt...
