 In recent years, air pollution has become a serious problem that humans urgently need to face. An adult breathes about 20,000 times a day and inhales 15 to 20 cubic meters of air. Long-term inhalation of polluted air can cause respiratory diseases and physiological dysfunction. Chronic bronchitis, bronchial asthma, emphysema and lung cancer. For this reason, wearing an air filter device has become a necessary choice for people to go out daily, and most of them are masks or masks. It has been confirmed by experiments that the filtration effect of the air filter device is closely related to the effective filtration area. The effective filter area of the general mask (mask) is small, and only the filter material close to the nasal cavity can exert the filtering effect, although the breathing is easy and the air resistance is small. However, the effect of sufficient filtration cannot be achieved. In order to improve the protective performance, it is often necessary to increase or thicken the filter material, but it also has defects such as large air resistance and difficulty in breathing, and the two are contradictory and cannot be obtained. In addition, due to the difference in face, the conventional masks (masks) have leaks in varying degrees, and the gap between the dirty air and the face through the mask (mask) is inhaled into the human body, and the true filtering effect cannot be achieved. In order to solve the contradiction between the filtering effect and the air resistance, Chinese Patent No. 200920293070.5 discloses a mask with a small air resistance and a small filtering performance, including a cover body and a lacing, wherein the cover body has a front filter layer and a rear filter layer. The cavity, the front filter layer and the rear filter layer are provided with a gas permeable support, and the middle of the filter layer has a breathing window matched with the nose and the nose.
