Problems solved by technology

Therefore, when a fire occurs, wearing a fire gas mask can greatly reduce casualties, but the smoke generated by the fire is so diverse that sometimes the mask cannot play the role of purification and protection.
[0003] Therefore, the existing air purification means for fire protection mask still needs to be improved

Abstract

The invention discloses an air purifying device for a fire protecting mask. The air purifying device comprises a polypropylene filter paper layer, an activated carbon layer, a photocatalysis layer anda quantitative active oxygen layer from outside to inside in sequence. The air purifying device has a function of filtering smoke fine particulate matters generated in a fire scene, can be used for adsorbing and decomposing toxic and harmful gas substances and achieves the aim of effectively avoiding damage of fire smoke inhalation to a human body.

Description

technical field [0001] The invention relates to the field of fire protection, in particular, the invention relates to an air purification device and a fire protection mask for fire protection masks. Background technique [0002] Fire is one of the major disasters that most frequently and universally threaten public safety and social development. When people use fire, they constantly summarize the law of fire occurrence, and reduce the harm caused by fire to human beings as much as possible. When fire occurs, people need to escape safely and quickly. Injuries to people caused by fire generally include direct burns and inhalation of toxic fumes from combustion, and most of the casualties in fires are caused by inhalation of fire fumes. Therefore, when a fire occurs, people in the fire scene can greatly reduce casualties by wearing fire gas masks, but the smoke produced by the fire is so diverse that sometimes the masks cannot play the role of purification protection. [0003...
