Self-absorption filtration type anti-particulate-matter breather

Abstract

The invention relates to a self-absorption filtration type anti-particulate-matter breather. The self-absorption filtration type anti-particulate-matter breather comprises an air filter, filtering cotton, a four-hole joint, an air outlet hole cover, a piston, a hose, a hose connector and a water bottle. The self-absorption filtration type anti-particulate-matter breather has two application schemes: firstly, the self-absorption filtration type anti-particulate-matter breather can be used in ordinary air environments, and air is inhaled through the filter and the four-hole connector; secondly, the self-absorption filtration type anti-particulate-matter breather can be used in dry air environments, air is inhaled by sequentially passing through the filter, the water bottle, the hose, the hose connector and the four-hole connector. The self-absorption filtration type anti-particulate-matter breather can save resources, is low in using costs and convenient to use, can completely and closely matched with nostrils so as to effectively filter the inhaled air, and causes no effects on the speaking and working of a user when being worn.

Description

technical field [0001] The present invention relates to a device for filtering polluted air, and more particularly to a self-priming filtering type anti-particulate breathing device. Background technique [0002] At present, my country's air pollution is very serious, especially in recent years, haze weather has occurred frequently. The causes of air pollution include both natural and man-made factors, especially man-made factors, such as industrial waste gas, combustion, automobile exhaust and nuclear explosions. With the rapid development of human economic activities and production, while a large amount of energy is consumed, a large amount of waste gas and soot is also discharged into the atmosphere, which seriously affects the quality of the atmospheric environment, especially in densely populated cities and industrial areas. When the concentration of pollutants in the atmosphere reaches a harmful level, it will destroy the ecological system and the conditions for the n...

Problems solved by technology

There are two types of masks on the market, which are mainly divided into surgical masks (medical masks) and dust masks (industrial masks). Surgical masks have poor air filtration effect due to poor tightness; dust masks are airtight Good fit, good air filtration effect, the amount of harmful substances in the inhaled gas has a lot to do with the tightness of the mask in contact with the nose

However, since the dust mask covers the nose and mouth, there are two disadvantages. 1. It is inconvenient to speak when wearing the mask; It will stay in the closed space, and when inhaling, it will inhale the gas exhaled in the closed space again, so that it cannot fully absorb the oxygen in the atmosphere; 3. The heat exhaled in the closed space is uncomfortable
