Dustproof respirator

Abstract

The invention relates to a dustproof respirator, in particular to a dustproof respirator which can be used semi-permanently. The dustproof respirator is convenient for breathing and talking, improve the wearing comfort and the dustproof effect and filter out the noxious air. The dustproof respirator consists of a main body of the respirator and wearing straps. The main body comprises an attachment member attached on the inner edge of the main body, a fixing frame forming an exhaust chamber in the inside center, a plurality of exhaust holes formed at two ends of the exhaust chamber, an exhaust plate inserted in the fixing frame, fixed together with the fixing frame and provided with a plurality of exhaust holes, a plurality of shielding films formed in front of the exhaust holes and opened when breathing, a filter hood formed into a whole at both sides of the main body of the respirator, a detachable and replaceable filter shell combined with the filter hood, and a dustproof supatex fabric, a carbon filter, an antimicrobial nano silver filter and a dustproof supatex fabric which are all arranged in sequence in the filter shell.

Description

technical field [0001] The present invention relates to a dust mask which can be used semi-permanently, enables convenient and comfortable breathing and talking, protects from harmful substances entering the nostrils, prevents water vapor from condensing on the mask and glasses during breathing, improves Wearing comfort, adhesion and dustproof effect, and filter out harmful substances in the atmosphere. Background technique [0002] Typically, in operating environments such as paper mills, textile mills and quarries, large amounts of dust are generated, and hazardous gases are emitted from chemical plants, welding plants, smelting plants, electroplating or metal processing plants. In addition, in our daily life environment, dust is harmful to our health in the subway or on the road. [0003] When these dusts and / or hazardous gases are inhaled, it may cause severe lung disease, such as asthma, etc. Therefore, dust masks are used in hazardous environments, such as industrial ...

AI Technical Summary

Problems solved by technology

[0006] However, conventional dust masks can only be used once, or used several times through washing, and therefore, they are costly or may cause hygienic problems

In short, traditional dust masks have such a structure that they cannot be used for a long time

[0007] In addition, because traditional dust masks have 2 to 3 layers of non-woven fabrics for filtering, the resistance to airflow is high, which makes breathing and speaking inconvenient

In particular, this problem becomes worse when dust collects on the filter after a while

[0008] In addition, traditional dust masks have such a structure that they cannot be close to the shape of the nose, thus creating gaps on both sides of the nose, allowing unfiltered dust-laden air to infiltrate
