Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, in particular to a breathing device for fire escape. Background Art

[0002] Fire is a sudden catastrophic event, usually caused by flames, high temperatures and smoke. Fires can occur in a variety of places, including homes, commercial buildings, industrial facilities and natural environments. Fires can cause serious casualties, property losses and environmental damage. When a fire occurs, people need to evacuate quickly, but the smoke and toxic gases produced by the fire hinder the evacuation of people, so a breathing device is needed to help people breathe normally.

[0003] After searching, the Chinese patent announcement number: CN208611619U discloses an escape respirator, which solves the technical problem that the escape respirator in the prior art inhales relatively more toxic and harmful gases. The escape respirator includes a protective mask, an air duct and an exhaust device. The protective mask is provided with a through hole, which is connected to one end of the air duct, and the other end of the air duct is connected to the exhaust device; the air duct extends from the mouth of the escapee to the calf; when the escape respirator is used, the exhaust device is installed on the calf of the escapee, the protective mask is installed on the mouth of the escapee, and the air duct connects the exhaust device with the protective mask. The utility model is used for when a fire occurs. Toxic and harmful gases are generally at a high place or move upward. An exhaust device is installed on the calf.
