Abstract

The invention relates to a waist carrying portable breather and belongs to the technical field of coal mine and fire protection rescue escaping. By means of the waist carrying portable breather, the problems in the prior art that breathers are large in volume, inconvenient to carry and use, high in breathing temperature and difficult in product effectiveness judgement are solved. The waist carrying portable breather comprises a mouth nose hood (1), a breathing pipe (2), an oxygen production portion (3), an air bag (4) and an upper cover (5), wherein the oxygen production portion (3) comprisesan oxygen production tank (31) and a three-way unit (32), the oxygen production tank (31) is provided with an observation window, one end of the breathing pipe (2) is connected with the mouth nose hood (1), the other end of the breathing pipe (2) is connected with the oxygen production tank (31) through the three-way unit (32), the three-way unit (32) is connected with the air bag (4), the air bag(4) is connected with the oxygen production tank (31), and the upper cover (5) is arranged on the oxygen production portion (3) in a covering manner. The waist carrying portable breather is convenient to carry and use, small in volume and high in heat dissipation efficiency, meanwhile, failure of an oxygen producing agent can be determined visually, and waist carrying portable breather is high insafety.

Description

technical field [0001] The invention relates to the technical fields of coal mine and fire rescue and escape, in particular to a portable respirator worn on the waist. Background technique [0002] When fire accidents occur in coal mines, buildings and other places, the victims trapped at the scene can not only use wet towels to cover their mouths and noses, or use self-rescue measures such as wearing filter breathing masks or compressed gas cylinder respirators, but also wear chemical oxygen. Respirators and other means for on-site evacuation and escape for self-rescue. However, the oxygen content in the air after violent combustion is low, and the toxic and harmful components in the smoke are very complex. However, wet towels and filter breathing masks can only filter a few specific toxic gases, and it is difficult to achieve the expected filtration and purification effect. Moreover, it is also not applicable to the environment where the oxygen concentration is lower than...
