Filtering nose mask

Abstract

The invention relates to an air filtering device, in particular to an air filtering nose mask. By the adoption of the air filtering nose mask, a user is unlikely to feel stuffy when wearing the air filtering nose mask. In order to further improve the comfort, the attractiveness, the practicability and the like of respiratory protective equipment, the air filtering nose mask comprises shell halves, a front shell, air filtering assemblies and a sealed air channel assembly. A cavity is formed between the front shell and the shell halves. The air filtering assemblies are arranged in the cavity. Vent holes are formed in the shell halves. The vent holes communicate with the air filtering assemblies. The air filtering assemblies communicate with the sealed air channel assembly. By the adoption of the filtering nose mask, the phenomenon that the user feels stuffy when wearing a nose mask is avoided through the shell half design; in addition, the user does not feel stuffy when wearing the filtering nose mask in summer; and the attractiveness is further improved.

Description

technical field [0001] The invention relates to an air filter device, in particular to an air filter nasal mask which is not easy to be stuffy when worn. Background technique [0002] In real life, air pollution is caused by industrial production and automobile exhaust emissions. Harmful substances such as floating dust, germs, and PM2.5 in the air have become invisible killers that endanger the health of the masses. For this reason, people have to adopt Wear respiratory protection to prevent infection from entering the nose. [0003] The respiratory protective equipment we commonly see in the market has a good effect on health protection, but it is sultry when worn in summer, and when worn in winter, the exhaled air is easy to fog the glasses. If it is a respiratory mask, the hot air exhaled Small water droplets will also be produced when the inner wall of the housing is cold, and the more the small water droplets gather, the more the wearing effect will be affected; and t...

[0003] The respiratory protective equipment we commonly see in the market has a good effect on health protection, but it is sultry when worn in summer, and when worn in winter, the exhaled air is easy to fog the glasses. If it is a respiratory mask, the hot air exhaled When the inner wall of the shell is cold, small water droplets will be produced. The more the small water droplets gather, the more the wearing effect will be affected; and the aesthetics of traditional respiratory protective equipment is not good.
