Mask of three-layer structure

Abstract

The invention discloses a mask of a three-layer structure. The mask comprises a mask body and mask bands. The mask bands are arranged on the two sides of the mask body, and a length adjusting mechanism is arranged on each mask band. The mask body sequentially comprises an inner mask cloth, a detachable filter component and an outer mask cloth. The detachable filter component comprises a PM 2.5 filter layer and an adsorption layer. The mask of the three-layer structure is simple in structure, low in cost and easy to manufacture; the filter component can filter out impurities, toxic gas and PM2.5 in external air; the filter component can be taken out and reused after being aired and disinfected, the situation that secondary pollution is caused to the inhaled air due to the fact that the mask body is not cleaned thoroughly is prevented, and the process of cleaning and airing the mask body is omitted. The mask of the three-layer structure has the functions of filtration, health care and life saving.

Description

technical field [0001] The invention relates to a mask with a three-layer structure. Background technique [0002] As a commonly used product for filtering the air entering the lungs, masks have a very good filtering effect when respiratory infectious diseases are prevalent and when working in a polluted environment such as dust. However, there are still many deficiencies in the popular masks today. For example, the edges of the existing masks are not tightly fitted to the face, and it is easy to leak air on both sides, which affects the filtering effect of the air, and it is difficult to ensure the face. Comfort; the existing masks have poor filtering effect on particulate matter that can enter the lungs of PM2.5 and below, and the filtering area is small, which makes it difficult to ensure adequate air filtration. If the material of the mask is thickened, it is difficult to ensure smooth airflow. through the mask. SUMMARY OF THE INVENTION [0003] The present invention...

AI Technical Summary

Problems solved by technology

But now popular mouth mask still has a lot of deficiencies, as, the fitting of existing mouth mask edge and face is not tight enough, easy both sides leaks air, affects the filtering effect to air, and it is difficult to guarantee the face Comfort; the existing masks have poor filtering effect on PM2.5 and below particulate matter that can enter the lungs, and the filtering area is small, so it is difficult to ensure sufficient filtration of air. If the material of the mask is thickened, it is also difficult to ensure smooth airflow through the mask
