Problems solved by technology
According to research data, only in the transportation and operation of petroleum and petroleum products, explosions and fire accidents caused by electrostatic discharge of human body are common all over the world, causing very huge economic losses every year
In the field of coal mines, due to the influence of static electricity, it will bring hidden dangers to the personal safety of miners
[0003] Static electricity is generated due to friction. With the development of the electronics industry, static electricity is causing more and more harm to human beings. For example, static electricity can interfere with the normal operation of radio equipment on airplanes and affect safety; static electricity is easy to absorb dust, causing pharmaceutical factories, etc. Pollution in places with high environmental cleanliness requirements; for the human body, the accumulation of static electricity in the human body may affect various diseases, etc.

The application relates to a safety face mask applied to a coal mine. The face mask comprises a face mask main body housing, a face mask filter piece, a face mask supporting part, a face mask filter piece replacing port, a gas supplementing part and a wearing part. The face mask filter piece which is in a layered structure is formed by an outer layer, an inner layer and a middle layer; the face mask supporting part is made from a hard metal wire; and the gas supplementing part comprises an outer housing and a gas supplementing ring, wherein the gas supplementing part is arranged on the outer side of the face mask filter piece of the face mask main body housing and is located in the lower middle part of the face mask main body housing.
Description
technical field [0001] The application relates to the field of safety masks, in particular to a safety mask used in coal mines. Background technique [0002] In flammable and explosive places, human body static electricity is one of the very serious sources of danger. Static electricity from human activities is an inevitable source of hidden dangers in field operations. According to research data, only in the transportation and operation process of petroleum and petroleum products, explosions and fire accidents caused by electrostatic discharge of human body are common all over the world, causing very huge economic losses every year. In the field of coal mines, due to the influence of static electricity, it will bring hidden dangers to the personal safety of miners. [0003] Static electricity is generated due to friction. With the development of the electronics industry, static electricity is causing more and more harm to human beings. For example, static electricity can ...
