Description

a mask

technical field

The utility model relates to the technical field of protective equipment, in particular to a mask.

Background technique

Masks are designed for people's health and are used to block some visible or invisible substances that are harmful to the human body, thereby avoiding adverse effects on the human body. The mask has a certain filtering effect on the air entering the lungs. Facts have shown that when respiratory infectious diseases are prevalent, many germs are transmitted through droplets, and wearing a mask can effectively reduce the infection rate. Or in some heavily polluted areas such as dust and smog, masks have a very good isolation effect.

Air pollution is a global and widespread problem, and it is a fact that we cannot change immediately under the general environment. With the continuous development of economy and society, air pollution is becoming more and more serious. The control of air pollution is a long process. In areas with serious air pollution, people often think of wearing masks to protect themselves and reduce the harm to the body from dust, sundries, and foreign objects in the air.

As a protective layer that isolates the human respiratory tract from the outside air, the dustproof performance of the mask directly determines the cleanliness of the air inhaled by the human body. A mask with good dust-proof and haze-proof performance can filter and purify dirty air, allowing the human body to breathe fresh and clean air.
