Description

The present invention relates to a highly safe emergency smokeproof mask.

According to the materials, more than 60% of the people who die in a fire die from smoke, inhale a large amount of smoke and toxic gas, lose consciousness, and die.

Smoke at a fire site has various substances, and also has toxic gases such as HCN, HS, and CO, and the most dangerous of them is carbon monoxide, which is generated by burning general building materials. The concentration of carbon monoxide is about 2.5%, but when the concentration of carbon monoxide is 1.3%, after a person inhales, the red blood cells in the body lose their oxygen carrying capacity and lose consciousness. It is fatal and therefore carbon monoxide is the most dangerous thing.

The most effective evacuation tool for fire scenes is smoke-proof masks, but older masks cannot be reliably worn, have poor visibility during wear, lack of thickness and poor heat resistance, poor filtration effect, It is difficult to evacuate due to drawbacks such as poor exhaust function.

Therefore, in response to the above problems, it is an object of the present invention to provide an emergency smoke-proof mask.

In order to solve the above-mentioned problems and achieve the above-mentioned object, the emergency smoke-proof mask of the present invention is used.
