Description

High leakproofness safety dust mask

Technical Field

The invention relates to the technical field of fire-fighting dust masks, in particular to a high-tightness safety dust mask.

Background

The fire-fighting dustproof mask is used as a personal protection device and is used for providing effective protection for respiratory organs, eyes and facial skin of people, consists of a mask, dust filtration and poison filtration, most of the existing poison filtration tanks are large in size and extremely inconvenient to use, and the fire-fighting dustproof mask is applied to fire sites, smoke and dust factories and other sections.

Present common dust mask all has certain life when using in the smoke and dust density of difference, the filter effect after exceeding the live time will direct variation until becoming invalid, secondly current fire control face guard wears the back, the stability of leakproofness is relatively poor, easily because of collision scheduling problem, lead to the face guard not to possess the leakproofness, thereby can lead to inside flue gas and dust do not easily enter into the face guard through filtration directly, contact with user's eye and respiratory track, cause the user to receive the injury, it is also comparatively troublesome also to have current face guard to wear, take time, so user's demand can not be satisfied.
