7. An oxygen ignition generator according to claim 6, wherein: a handle (24) is detachably arranged on the top of the sealing cover (22) and positioned on the outer side of the end cover (28).
8. An oxygen ignition generator according to claim 1, wherein: the medicament (26) is prepared from the following raw materials: sodium chlorate, a catalyst, a chlorine inhibitor and a binder.
9. A method of operating an oxygen ignition generator according to any one of claims 1 to 8, comprising the steps of:
s1, connecting an ignition terminal to main control equipment, and placing an oxygen generating device above the ignition device;
s2, the main control equipment provides a 12V ignition pulse signal for the ignition device;
s3, triggering an ignition wire in the oxygen generating device to generate high temperature, and activating a catalyst in the medicament at the high temperature to trigger the high-temperature melting point of sodium chlorate to decompose oxygen;
and S4, continuously generating oxygen in the metal shell at the moment, increasing the pressure in the shell, jacking up the safety film, and releasing the oxygen from the screen plate after the safety film is pierced to generate oxygen for a closed environment.
10. The method of operating an oxygen ignition generator according to claim 9, wherein:
in the step S4, when the medicament is continuously converted into oxygen, the weight of the oxygen generating device is continuously reduced, and when the pressure sensor of the ignition device senses that the weight is lower than a set value, the ignition signal is stopped, the reaction is terminated, and the main control equipment is provided with a prompt that the oxygen generating device is invalid or not installed.
