Abstract

The invention relates to a dustproof gas mask, comprising a mask main body, an expiratory valve cap, a seal washer and a filter, wherein the expiratory valve cap is arranged at the front part of the mask main body. The dustproof gas mask is characterized in that the seal washer is formed by bonding open-type rubber parts, and the seal washer is arranged at the rear part of the mask main body and is provided with an air inlet hole which is provided with an inflating valve. The part of the inner side of the seal washer touching with the lower jaw of the face of a human body is provided with an anti-skidding piece, and the wall of the part of the seal washer touching with the face of the human body is thinner than other parts. The expiratory valve cap is provided with a louvered-fin air outlet hole, and the direction of the louvered-fin air outlet hole is sloping downward. The dustproof gas mask has the characteristics of comfortable wearing and good tightness.

Description

technical field [0001] The invention relates to a breathing mask, which belongs to the technical field of labor protection articles, in particular to a dust-proof gas mask and a manufacturing method thereof. Background technique [0002] At present, the traditional dust-proof and gas masks used in labor protection products are composed of a mask body, a poison box, an exhalation valve and a tie. The mask body is made of soft rubber or rubber and plastic. The same material is bent, the main body of the mask is too soft and it will deform when worn, the gasket is made of single-layer rubber molded and bent, the material is poor in softness, the wall of the gasket is relatively thick, and the pressure on all parts of the face is the same. Wearing it for a long time will have a sense of oppression on some parts of the face, and will leave indentations on the face, and the wearing comfort is not good; for this reason, I applied for a patent number of 2004200676730 to the State In...
