When methane gas or oxygen-deficient air is released and carbon monoxide is generated, an oxygen generating agent such as potassium superoxide (KO 2 ), which reacts with water and carbon dioxide in exhaled breath to generate oxygen, is used. Oxygen self-contained breathing apparatus are known. This oxygen self-contained breathing device consists of a facepiece, an oxygen generating can, a breathing bag, etc., but the rate of oxygen generation is generally slow at the beginning of wearing, and it usually takes 1 to 3 minutes to generate enough oxygen for breathing. The problem is that it takes about a minute. For this reason, as a means to obtain the oxygen necessary for initial breathing, for example, a small oxygen generating can having an oxygen generating agent, a water ampoule, a firing pin, etc. is provided in the oxygen generating agent filling part of the oxygen generating can, and a stop pin is attached to the outside. Initial generation accelerator for oxygen generating cans for masks, which was brought out in 1973.
-93996 Publication) and an oxygen generation auxiliary can that further includes an oxygen generating agent, a water ampoule, a ring, etc. inside the oxygen generating can, and the steel wire bound to the ring is pulled out of the oxygen generating can. There are accelerators (Utility Model Application No. 50-64192).

However, these devices have an oxygen generating agent, a water ampoule, a breaking mechanism, etc. in the oxygen generating agent filling part in the oxygen generating can, and are an initial generation accelerator that is combined with the oxygen generating can, so the overall structure of each of them is extremely small. Not only is it complicated and difficult to process, inspect, and maintain, but the generated oxygen is vigorously blown onto the external oxygen generating agent layer along with the mist, causing the oxygen generating agent layer to become clogged with powder and mist. There was a problem in that this caused a problem in that the original function of the oxygen generating can was subsequently hindered.

As a result of repeated research, we arrived at this idea.
