Abstract

The invention discloses a novel gas mask. The novel gas mask is reasonable in structural design, a silica gel soft body comprises a first glue layer and a second glue layer, the air leakage phenomenon caused by face movement of a user is effectively controlled, and the novel gas mask has the advantage of being tight in protection; and meanwhile, four filtering layers are arranged in the filtering box, the filtering effect is greatly improved, and the device is easy and comfortable to wear and has the advantages of being good in filtering effect, safe, tight in protection and high in universality.

Description

technical field [0001] The invention relates to a protective appliance, in particular to a novel gas mask. Background technique [0002] A gas mask is a personal special labor protection product, and it is also an individual protective product. It is worn on the head to protect people's respiratory organs, eyes and face, and is a personal protective equipment to prevent poisonous gases, dust, bacteria, toxic and harmful gases or steam and other toxic substances. . Gas masks are widely used in the fields of petroleum, chemical industry, mining, metallurgy, military, fire protection, health and epidemic prevention, and machinery manufacturing, and can also play an important role in personal respiratory protection in cities with severe smog and photochemical smog. [0003] However, there are still some deficiencies in existing gas masks when they are used. First, the traditional filter device is only provided with a coarse filter layer, and the air purification rate is not hig...
