Dustproof gas mask

Abstract

The invention provides a dustproof gas mask, which comprises a mask, a respiration device, two filters, a lower bracket, protection goggles and a mask rubber band. A respiration device installation port is formed in the mask. Two filter installation ports are also formed in the two sides of the respiration device installation port in the mask. The respiration device is arranged in the respiration device installation port. The two filters are respectively arranged in the two filter installation ports. The protection goggles are arranged on the mask. The lower bracket is arranged in the mask. The two ends of the mask rubber band are respectively connected with the two ends of one side close to the protection goggles on the mask. The dustproof gas mask provided by the invention has the advantages that the parts of the mask are easy to disassemble and assemble, the mask is convenient to carry and wear, the weight of the mask is lighter and no uncomfortable feeling is caused to a user who wears the mask; since the dustproof gas mask is provided with the detachable protection goggles, the glasses can be conveniently replaced, the pupil distance can be conveniently adjusted and the dustproof gas mask can meet the wearing and labor protection demands of different patients who suffer from refractive errors.

Description

technical field [0001] The invention relates to the field of safety protection, in particular to a poison-proof and dust-proof mask. Background technique [0002] At present, the anti-virus and dust masks for military or civilian use are generally composed of a mask, a breathing mouth, a filter and a rubber belt. On the wearer's head, it plays the role of filtering the air entering the mask, preventing the wearer from inhaling poisonous gas or dust. Some existing anti-poison and dust-proof masks also can be equipped with protective goggles, and protective goggles, mask and other parts are integrally made, and protective goggles are worn together when wearing mask, prevent poisonous gas or dust from entering the wearer's eyes. However, since the protective goggles and the mask are integrally formed, this kind of anti-virus and dust-proof mask with protective goggles can only be customized to suit the different situations of different wearers, which is costly, time-consuming ...

AI Technical Summary

Problems solved by technology

However, since the protective goggles and the mask are integrally formed, this kind of anti-virus and dust-proof mask with protective goggles can only be customized to suit the different situations of different wearers, which is costly, time-consuming and labor-intensive, and inconvenient; Moreover, the physical size of this anti-virus and dust-proof mask is relatively large, and it cannot be disassembled and assembled under different harsh working environments such as smoke, poisonous gas, etc., resulting in a large footprint and a large weight, which is not easy to carry and wear, and is easy to wear. In addition, the protective goggles of this anti-virus and dust mask are designed for flat light, which is not suitable for patients with refractive errors.
