Abstract

The invention discloses an isolated type compressed oxygen self-rescuer which comprises a lower shell and an upper shell, wherein the upper shell is in buckling connection with the lower shell through a fastener; a spacing plate for separating the inner space of the lower shell into a first area and a second area is arranged in the lower shell; an oxygen bottle is arranged in the first area; an air bag connected with the oxygen bottle is arranged in the second area; a breather valve and a breather hose are mounted at an opening of the air bag; a gas separating film for dividing the inner space of the air bag into two parts is arranged in the air bag; the top of the gas separating film is spliced with a middle isolating frame in the breather valve; a nasal splint is connected with the breather hose through a connecting belt; a vent valve is mounted on a side wall of the lower part of the air bag; a waist tag is arranged on the outer wall of the lower shell; an observation window is arranged at the top of the upper shell. The isolated type compressed oxygen self-rescuer has the advantages of simple structure, reasonable design, convenience in processing and manufacturing, light weight, complete function, long breathing time, high practicability, low implementation cost, good use effect and convenience in popularization and application.

Description

technical field [0001] The invention relates to a personal respiratory protection device, in particular to an isolated compressed oxygen self-rescuer. Background technique [0002] The isolated compressed oxygen self-rescuer is a personal respiratory protection device. It is of great significance to help employees escape when there is hypoxia in coal mines or when toxic or harmful gases endanger the lives of miners. Compared with the isolated chemical oxygen self-rescuer, this type of self-rescuer has the obvious advantage that the temperature does not rise during operation, and has great advantages in ensuring the safety of underground workers. However, such self-rescuers generally have the problems of heavy weight and short breathing time at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an isolated compressed oxygen self-rescuer, which has a simple structure, reasonable design, convenient processin...
