Abstract

A gas mask facilitating conversation comprises a mask body; the mask body is provided with a breathing valve and an eye window; a conversation diaphragm assembly is arranged on the breathing valve and comprises an outer shell; the outer shell is composed of an upper buckle and a lower clamp; the upper buckle is of an arch structure; a clamping groove is formed in the edge of the lower clamp; the upper buckle is buckled with the lower clamp through the clamping groove; and sound diaphragms are arranged on the lower clamp and the upper buckle. By the adoption of the structure, on the basis of well meeting the demand of communication between mask wearers, the sound transmission loss is effectively reduced when sound passes through the mask.

Description

technical field [0001] The invention relates to a gas mask, in particular to a gas mask which is convenient for the wearer to transmit sound. Background technique [0002] As personal protective equipment, gas masks are used to provide effective protection for personnel's respiratory organs, eyes and facial skin. The gas mask is mainly composed of filter element, cover body, eye window, exhalation communication device, headband and other components. They each have their own responsibilities and can cooperate tacitly at the same time. [0003] Wherein the cover body of the gas mask is the main component that forms each part as a whole, and people usually need electronic equipment to assist communication when wearing a gas mask, so after electronic equipment is set on the gas mask, the production cost of the mask will be greatly increased The weight of the large mask itself seriously affects the portability of the mask. Contents of the invention [0004] The technical prob...
