Abstract

The application belongs to the field of anti-poison devices, and particularly relates to an anti-poison respirator for a chemistry laboratory. The anti-poison respirator comprises a respirator main body and respirator strips. An elastic adjusting device is arranged on the respirator strips. A nasal splint or a nasal pressing strip is arranged on the upper edge of the respirator body. A neck protection part is arranged on the lower edge of the respirator main body. The respirator main body comprises a skin-friendly layer, a first non-woven fabric layer, a sponge layer, an adsorption layer, a filtering layer, a second non-woven fabric layer and a fire-proof layer, which are arranged in sequence from inside to outside. The anti-poison respirator has the beneficial effects that the structure is simple, the use is convenient, and the respirator is used more comfortably due to the arrangement of the skin friendly layer.

Description

technical field [0001] The application belongs to the field of anti-virus equipment, in particular to a gas-resistant mask for a chemical laboratory. Background technique [0002] Mask is a kind of sanitary product, which generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose.
