[0005] Adopting the above technical solution: When using the improved oxygen generator, when oxygen is needed, the operator presses the pressing end of the piezoelectric igniter, and the piezoelectric igniter transfers the electricity generated by the internal piezoelectric ceramic to the wiring terminal and the ignition wire. The ignition wire prompts the ignition of the ignition agent. Among them, the ignited ignition agent contacts the medicine column, and the medicine column is mainly chlorate; the role of the metal fuel is to undergo an oxidation reaction with oxygen, releasing a large amount of heat to provide heat for the decomposition process of the medicine column; the role of the catalyst is to lower the decomposition temperature of the oxygen source; the role of the binder is to promote the shaping of the medicine column.
