Chemical oxygen fire protection self-rescue respirator capable of achieving heat dissipation and cooling easily

Abstract

The invention provides a chemical oxygen fire protection self-rescue respirator capable of achieving heat dissipation and cooling easily. The chemical oxygen fire protection self-rescue respirator comprises a mask 1, a respirator cover 2, an airbag 3 and an oxygen generator 4. In the using process, gas (carbon dioxide and water vapor) breathed out from a human body enters the oxygen generator 4 through an exhaling one-way valve of the respirator cover 2 and is reacted with an oxygen generating agent 5, generated oxygen enters the airbag 3 downwards, and the generated oxygen enters the respirator cover through the exhaling one-way valve of the respirator cover 2 after circulation cooling to allow the human body to breathe. The problems that an oxygen generator of a traditional chemical oxygen fire protection self-rescue respirator is placed in the airbag, hence, heat dissipation can not be achieved easily, and the breathing temperature is high; the airbag-shaped structure of the self-rescue respirator can cause gas short circuit easily, and high-temperature oxygen generated by the oxygen generator can be directly breathed in by the human body are solved. An isolating type gas defense and smoke prevention oxygen self-generation respirator which is capable of achieving heat dissipation and cooling easily, low in breathing temperature and smooth in breathing is provided.

Description

technical field [0001] The invention relates to a chemical oxygen fire-fighting self-rescue respirator used in the fire-fighting field, which is used for self-rescue and escape of personnel in an oxygen-deficient and toxic and harmful gas environment when a fire occurs. In particular, it relates to a chemical oxygen fire-fighting self-rescue respirator which is easy to dissipate heat and cool down. Background technique [0002] Chemical oxygen fire self-rescue respirator is a personal respiratory protection device made of the principle of oxygen generation by chemical agents, and is widely used in fire or other disaster environments, such as hotels, entertainment, office places, mines, military equipment, etc. The current chemical oxygen self-rescuers generally have the following defects: First, the oxygen generating tank is placed in the air bag, which is not conducive to heat dissipation; second, the oxygen generating tank has no cooling device, which has poor heat conduct...

AI Technical Summary

Problems solved by technology

The current chemical oxygen self-rescuers generally have the following defects: First, the oxygen generating tank is placed in the air bag, which is not conducive to heat dissipation; second, the oxygen generating tank has no cooling device, which is not good in heat conduction and heat dissipation, and the ambient temperature is overheated, or the process of chemical oxygen generation The heat generated will cause the wearer to overheat the inhaled gas, resulting in poor comfort; thirdly, the airbag shape and structure of the self-rescuer can easily form a short circuit of the airflow, causing the high-temperature oxygen generated by the oxygen tank to be directly inhaled by the human body
