At present, with the development of urbanization and industrialization, the automobile exhaust pollution, the industrial production pollution and the home decoration pollution are increasingly serious, people are easily damaged by polluted air both outdoors and indoors, and the pollution is more serious in winter. Allergens such as haze, dust, pollen, mites, irritant gases and the like are inhaled into the respiratory system by a person, and allergic rhinitis, asthma and the like are generated. The virus is inhaled into the body, causing diseases.
In order to prevent toxic and harmful air from being inhaled into human body, people use various masks to protect themselves. Patent No. 201320477806.0 discloses a fill in the nostril and use, abundant filtered air's nose stopper formula air filter box, and patent No. 201580003194.3 discloses a nasal cavity insertion type gauze mask, and patent No. 201620190702.5 discloses the better intelligent electronic gauze mask ability of filtering fine particles such as PM2.5 of gas permeability. Common masks on the market are: various types such as common masks such as disposable masks, gauze masks, dust masks, common medical masks and the like, special masks such as industrial masks, N95 masks, KN95 masks and the like, disposable invisible filtering nasal plugs and the like.
Ordinary gauze mask can not prevent pollen, dust, mite, virus, irritant gas, gaseous pollutants etc. to permeate through gauze mask and get into the respiratory track, and ordinary gauze mask also can not fine laminating with the face, and the leakproofness is poor, and above-mentioned gaseous pollutants, allergen etc. can permeate the gap, get into nasal cavity, internal, can't reach the effect of complete protection. The special mask can prevent toxic and harmful air from being inhaled into the body, but has good tightness and poor air permeability, and is easy to lack oxygen after being worn for a long time. The disposable invisible filtering nasal plug has too little filtering material, short protection time, poor protection effect, disposable use, high price and poor economical efficiency, and cannot become the mainstream.
More importantly, most of the masks cover both nostrils and mouths, so that the users are inconvenient to talk and eat, and particularly, when the users eat the food, the users need to take off the masks to expose the users to toxic and harmful air, so that the protection effect is reduced sharply.
