Anti-gas anti-explosion mask

Abstract

The invention discloses an anti-gas anti-explosion mask, characterized by comprising a hood, a cappa, an air supply device and a communication device. The hood comprises a face shield and a head cover, and an air guiding tube facing the face shield penetrates from the back position of the hood; the air guiding tube is connected with a corrugated hose located outside the hood, and the corrugated hose is connected with the air supply device to realize micro-positive pressure air supply; the inside of the hood is provided with a two-way exhalation valve at the position of the temple; the cappa isof a double layer structure including an anti-gas layer and an anti-explosion layer; the upper part of the cappa is arranged inside the hood in a connection manner; the air supply device comprises amotor, a fan and a canister, the canister is internally provided with a smoke filter layer and a toxin filter layer; the communication device comprises a bone conduction earphone and an interphone, and an interference filtering device is arranged in front of the bone conduction earphone; a rechargeable battery is arranged in a package box, and the fan is sealed in the package box. According to theanti-gas anti-explosion mask provided by the invention, two functions of anti-gas and anti-explosion are integrated, and the anti-gas anti-explosion mask can be widely applied to chemical productionor other technical fields requiring anti-gas and anti-explosion.

Description

technical field [0001] The invention relates to the technical field of anti-virus and explosion-proof equipment, in particular to an anti-virus and explosion-proof mask. Background technique [0002] At present, chemical production products involve various technical fields such as industry and agriculture, such as pesticides for crops, paints for construction, drug synthesis in the pharmaceutical field, etc., and the chemical industry and chemical production often encounter toxic and explosive environments. If an explosion occurs , will cause injury to the head, face and neck of the personnel. Furthermore, large-scale thermal power plants, when the operators need to perform dangerous operations such as switching, because large sparks will be generated at the moment of switching, if the operating personnel do not wear work clothes with explosion-proof functions, it is very difficult. May be life threatening. Existing mask function is more single, can not take into account t...

Problems solved by technology

Furthermore, large-scale thermal power plants, when the operators need to perform dangerous operations such as switching, because large sparks will be generated at the moment of switching, if the operating personnel do not wear work clothes with explosion-proof functions, it is very difficult. may be life threatening

Existing mask function is more single, can not take into account the double effect of anti-explosion and anti-virus, therefore, this will undoubtedly restrict the development of industry, and can cause more serious life threat to user
