Summary of the invention
The purpose of this utility model just provides a kind of convenient gas mask with tight isolation effect.
Technical solutions of the utility model are: comprise cover body and cover band, the cover band is connected the two ends of cover body, at the lower limb of described cover body loosing and tightening structure is arranged, and sews up to the midline at middle part, cover body top, forms a projection forward in the middle and upper part of cover body; Interlayer is arranged in cover body, in this interlayer, be provided with anti-toxic dust filter core.
Described anti-toxic dust filter core is made of overlapping successively textile adhesive plaster, micropore filter paper, active carbon layer, suede cotton, and textile adhesive plaster has viscose glue one side and micropore filter paper bonding, the periphery suturing with thread management of this anti-toxic dust filter core.
Described cover body is followed successively by Gao Zhibu, nonwoven, eyelet fabric or single Chinese cloth from skin to internal layer, and this cover body is horizontal broadband shape, and middle part broad, described anti-toxic dust filter core are between nonwoven and eyelet fabric, and described eyelet fabric is having an opening near the end.
Described face shield band is an elastic cord, and it passes the with holes of cover body two ends, and two through holes regulating on the fastener are passed at the two ends of this elastic cord.
Described micropore filter paper is medical qualitative filter paper.
The projection forward that the utility model forms in the middle and upper part of cover body and the loosing and tightening structure of lower limb can make cover body can closely cover face, especially blocked the passage of wing of nose both sides, prevented that Toxic and the dust in the atmosphere from entering respiratory tract, increased the dustproof effect of gas defence of face shield greatly.This natural projection has also been avoided the direct pressing face of cover body, under the use that does not have nose clip, realizes safely and comfortable equally, certainly, if not only safety of nose clip effect is arranged, also has attractive in appearance and leading sense of the times (both can).
