[0002] The smoke in the fire scene is poisonous, and many victims died of suffocation due to inhalation of poisonous gas. If a fire breathing device is equipped, it can resist the invasion of toxic smoke and escape successfully in a critical moment; general fire breathing devices include: Smoke mask, smoke mask is a necessary personal fire protection respiratory protection device in hotels, restaurants, office buildings, shopping malls, public entertainment places and residential buildings; the smoke mask is composed of a mask and a filter module, mainly used to absorb fire Toxic smog generated in the air provides space for users to breathe; most of the filter modules in the smoke mask use activated carbon to absorb toxic smog, such a filter module absorbs a limited amount of smog and cannot provide users with maximum filtering effect; In places where the fire scene is serious, a large amount of smoke will be produced, and the user will also be affected by the smoke that is not completely filtered; because the temperature of the fire scene is high, the smoke will also be accompanied by a high temperature. When the user When using a smoke mask, the toxic smoke will also bring part of the high temperature into the smoke mask, making the user uncomfortable to breathe; the current smoke mask users must strengthen due to the structural characteristics of the smoke mask when using it. Breathing can only be carried out by breathing force, which is not conducive to the use of users in emergency escape, so there are defects
