Efficient oxygen-generation and air stagnation prevention chemical oxygen fire-fighting self-rescue respirator with cooling layer

Abstract

The invention provides an efficient oxygen-generation and air stagnation prevention chemical oxygen fire-fighting self-rescue respirator with a cooling layer. The chemical oxygen fire-fighting self-rescue respirator comprises a mask (1), a breathing cover (2), an oxygen-generation tank (3) and an airbag (6), and is characterized in that the breathing cover is arranged on the mask and is connected with an opening of the airbag; an expiration one-way valve and an inspiration one-way valve are arranged at the connecting position of the breathing cover and the airbag; the oxygen-generation tank is arranged in the airbag, and an air inlet in the top of the oxygen-generation tank is connected with the breathing cover through the expiration one-way valve; meanwhile an air guide tube is connected with an air outlet in the bottom of the oxygen-generation tank. According to the self-rescue respirator, the oxygen-generation tank is arranged in the airbag, the airbag is effectively prevented from being wrinkled or adhered, and the air stagnation phenomenon is completely eradicated; a flow channel subdivision staggered fin type cooling structure is adopted in the oxygen-generation tank, the problem that the reaction in a medicament layer is uneven and the cooling problem are effectively solved, and meanwhile the temperature of generated oxygen is effectively lowered through the arrangement of a supporting heat conduction separation plate, a heat isolation layer and the air guide tube.

Description

technical field [0001] The invention relates to an isolated anti-virus and anti-smoke self-generating oxygen respirator applied in the field of fire protection, which is used for self-rescue and escape of personnel in the environment of toxic and harmful gases and hypoxia in the event of a fire, especially relates to a cooling layer that can efficiently generate oxygen And anti-stagnation chemical oxygen fire-fighting self-rescue respirator. 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 reaction of the oxygen generation tank is uneven and the resistance is large; the oxygen generation tank has no cooling device, and th...

Problems solved by technology

The current chemical oxygen self-rescuers generally have the following defects: First, the reaction of the oxygen generating tank is uneven and the resistance is large; the oxygen generating tank has no cooling device, and the heat conduction and heat dissipation are not good. Cause the wearer to inhale gas overheating, poor comfort; second, the air bag of the self-rescuer is prone to folds or adhesions, causing stagnation in the breathing airflow, and the airflow is not smooth; high concentration of carbon dioxide
