The utility model adopts the following technical scheme: the utility model relates to a half face guard formula gas mask of single box, include gas mask body, air inlet valve block, exhale valve gap, wear headstock, elastic cord and elasticity and detain, be equipped with the air inlet on the gas mask body, be equipped with the air inlet valve mount pad on the air inlet, the air inlet valve block mountable is located on the air inlet valve mount pad, be equipped with the exhale valve mount pad on the gas mask body, exhale valve block mountable is located on the exhale valve mount pad, be equipped with the elastic cord perforation on the gas mask body, it sets up for scalable regulation annular to wear the headstock, the elastic cord passes the elastic cord perforation mountable and locates on wearing the headstock, the elasticity is detained the mountable and is located on the elasticity area.

Furthermore, the inner side of the gas mask body is processed by encapsulation, so that the sealing performance is good.

Furthermore, the inner side of the gas mask body is made of TPE materials, so that the gas mask is comfortable to wear and is nonhazardous.

Furthermore, the thickness of the nose bridge of the gas mask body is thinner than that of the nose bridge at other positions, so that the pressure of the nose bridge is relieved.

Furthermore, the caliber of the exhalation valve plate is 28 mm.

Adopt above-mentioned structure the utility model discloses the beneficial effect who gains as follows: this scheme half face guard formula gas mask of single box can ann tear the setting of adjusting open through whole adoption, be convenient for clean and disinfect, do benefit to used repeatedly, and the suitability is wider, through setting up the expiratory valve lid, the washing and the disinfection of the valve block of exhaling of being convenient for, the inboard TPE rubber coating that adopts of gas mask body, the leakproofness is better, and to the design of bridge of the nose decompression, it is higher to make the travelling comfort, and with expiratory valve block aperture increase setting, can reduce the expiratory resistance, the person of facilitating the use smoothly breathes.
