Automobile exhaust filtering respirator for traffic police

Abstract

The invention discloses an automobile exhaust filtering respirator for traffic police. The automobile exhaust filtering respirator comprises an inner layer, a middle layer and an outer layer, wherein the outer layer is a bowl-like carbon dust filtering layer; the middle layer is a tile toxic gas filtering layer; a paster fit with the wing of nose is stitched in the middle; the inner layer is a reticulated gauze layer; and mixed particles consisting of active carbon, manganese dioxide and copper oxide are added in the toxic gas filtering layer. The automobile exhaust filtering respirator has the characteristics of safety, comfort, convenience, attractiveness and good filtering effect, and is suitable for traffic police and related personnel facing automobile exhaust for a long time.

Description

technical field [0001] The invention relates to a novel mask, in particular to a vehicle exhaust filter mask used by traffic police. Background technique [0002] There are one or two hundred compounds of different properties in the exhaust emitted from automobiles, mainly carbon monoxide, carbonic acid compounds and nitrogen oxides, as well as solid particles (carbon black) and lead dust generated by burning leaded gasoline. . Among them, after carbon monoxide is inhaled, it will combine with hemoglobin in the body to form carbon hemoglobin, thereby destroying red blood cells, leading to dizziness, fatigue, agitation, lack of energy, emotional instability, etc., that is, hypoxia, similar to gas poisoning. Hydrocarbons and nitrogen oxides can produce chemical smog when exposed to sunlight, causing eye and respiratory diseases in people. Carbon black can irritate the human respiratory tract. After lead dust enters the blood of the human body, it will cause human symptoms si...

Problems solved by technology

However, for carbon monoxide or some fine dust in automobile exhaust, it will pass through the mesh of the gauze and enter the respiratory system, and the general mask is not tightly sealed with the human face, and many dangerous substances in the air will leak from the non-closed place Go in, and in order to increase the filtering effect, the general filter mask increases the thickness, which will cause the breather to have difficulty breathing and cannot meet the needs of the human body
