Description
Technical Field
The utility model relates to a mask, in particular to an invisible mask which inserts one end of an air inlet and outlet pipe into a nostril.
Background
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 plug formula air cleaner, 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.
