Abstract

The invention provides a gas mask. The gas mask comprises a body and a neck sleeve arranged at the bottom end of the body. A big eye widow and a gas defense base are fixedly arranged on the body. A fixing belt is arranged on the two sides of the gas defense base and fixedly provided with an adjusting buckle. A gas defense device is arranged at one end of the gas defense base. A first protective net, a second protective net and a third protective net are fixedly arranged in the gas defense device. An activated carbon layer is fixedly arranged between the first protective net and the second protective net. A sodium oxide layer is fixedly arranged between the second protective net and the third protective net. Airbags are symmetrically arranged on the two sides of the sodium oxide layer. The gas mask is simple in structure, low in making cost, convenient to use and high in practicality. Due to the arrangement of the adjusting buckle, the size of the fixing belt is conveniently adjusted through the adjusting buckle, and people in different sizes can conveniently use the gas mask. Due to the arrangement of the sodium oxide layer, exhalant carbon dioxide and sodium peroxide react to generate oxygen which is stored in the airbags, oxygen inhaled into the human body then passes through the sodium peroxide layer to form oxygen, and therefore the gas mask can be continuously used for gas defense for several days.

Description

technical field [0001] The invention relates to a mask, in particular to a gas mask. Background technique [0002] A gas mask is a personal special labor protection product, and it is also an individual protective product. It is worn on the head to protect people's respiratory organs, eyes and face, and prevent poisonous substances such as poisonous gas, dust, bacteria, poisonous and harmful gases or steam. personal protective equipment. Gas masks are widely used in petroleum, chemical industry, mining, metallurgy, military, fire protection, emergency rescue, health and epidemic prevention, technology and environmental protection, machinery manufacturing and other fields, and can also play an important role in cities with severe smog and photochemical smog. Respiratory protection. Gas masks can be divided into full-face masks and half-masks in terms of shape, and full-face masks are divided into positive pressure and negative pressure. [0003] The gas mask is mainly co...
