Positive pressure type fire-fighting air breathing apparatus

Abstract

The invention relates to a positive pressure type fire-fighting air breathing apparatus. The positive pressure type fire-fighting air breathing apparatus comprises an oxygen supply bottle (4), an oxygen catheter (3) and a hood (1). The oxygen supply bottle (4) is connected with the hood (1) through the oxygen catheter (3), and a thermometer (2) is clamped on the oxygen catheter (3) on the lower portion of the hood (1). Due to the fact that the thermometer (2) is arranged, a fireman can know the environment temperature condition of the place where the fireman is located at any moment in the process of executing a fire-fighting task, and the fireman can know and master the environment condition of the fire-fighting place more deeply. The fire-fighting efficiency is improved, and meanwhile a certain role in protecting the personal safety of the fireman can be played.

Description

technical field [0001] The invention relates to the field of fire-fighting rescue respirators, in particular to a positive-pressure fire-fighting air respirator. Background technique [0002] At present, in fire rescue, especially in toxic or harmful gas environment, harmful substances such as smoke and dust, and hypoxic environment, respirators are basically used. Among them, positive pressure fire-fighting air respirators are mostly used. Common positive pressure type fire-fighting air respirator, its structure generally comprises the oxygen supply bottle that connects in sequence, pressure reducing valve, oxygen supply pipe, oxygen connection pipe and hood. The respirator of this structure simply provides an oxygen supply device for firefighters in the process of performing tasks, but does not provide firefighters with more relevant information about their own working environment, thus making firefighters The firefighters do not know the environment they are in, for exa...

AI Technical Summary

Problems solved by technology

The respirator of this structure simply provides an oxygen supply device for firefighters in the process of performing tasks, but does not provide firefighters with more relevant information about their own working environment, thus making firefighters Firefighters do not know the environment they are in, for example, they cannot provide firefighters with information about the temperature of their environment, in which direction the temperature is rising, and in which direction the temperature is falling.

Therefore, it is impossible for firefighters to understand the ambient temperature conditions of the location more effectively, so that firefighting tasks cannot be performed more effectively.

At the same time, it cannot provide better protection measures for the personal safety of firefighters.
