The invention relates to an isolation type chemical oxygen self-rescuer for an underground coal mine, in particular to a failure self-detecting type chemical oxygen self-rescuer. The failure self-detecting type chemical oxygen self-rescuer comprises a breathing mouth assembly, an airbag assembly, an oxygen generating tank assembly, an early oxygen supplying assembly, a failure self-detecting assembly and a protective upper cover assembly; the oxygen generating tank assembly comprises a shell, an isolation box is supported in the shell, an airflow equipartition pad is arranged in the isolation box, a first filter pad is arranged under the airflow equipartition pad, and an oxygen generating agent is placed in the isolation box; the early oxygen supplying assembly comprises a gland, a water storage tank and an oxygen generating cover; the failure self-detecting assembly comprises a detecting box, and a self-detecting circuit is arranged in the detecting box; the protective upper cover assembly comprises a shell upper cover. According to the failure self-detecting type chemical oxygen self-rescuer, the brand new design is achieved, the failure self-detecting function is achieved from material usage of a self-rescuer shell, a method of early oxygen generation and the overall structure of the self-rescuer by adopting an electronic technology and an micro-computer technology, and therefore the failure self-detecting type chemical oxygen self-rescuer has the very high technological content.
Description
technical field [0001] The invention relates to an isolated chemical oxygen self-rescuer for underground coal mines, in particular to a failure self-inspection type chemical oxygen self-rescuer. Background technique [0002] The isolated chemical oxygen self-rescuer is a personal respiratory protection device that uses the principle of chemical potassium superoxide to generate oxygen. It is mainly suitable for underground mining operations in coal mines. When the lack of oxygen in the environment or the occurrence of harmful and toxic gases endanger the lives of miners, miners can wear them in time to quickly evacuate the disaster area and achieve the purpose of escape. [0003] The working principle of the existing isolated chemical oxygen self-rescuer is: the oxygen needed by the human body at the initial stage of wearing is provided by the oxygen cylinder, and it is not restricted by the harmful gas in the surrounding environment when it is used. When the wearer exhales, ...
