Integral ignition structure and compressed-gas-type fuel gas generator

An integral ignition structure, comprising an ignition box, an igniter, and an end cover, wherein the ignition box has a closed end and an open end opposite to closed end;

• the igniter is provided at the closed end;
• and the end cover is provided at the open end, and is arranged to form, together with the ignition box, an ignition chamber, wherein at least one flow-through hole for communicating with the ignition chamber is formed in the end cover, an ignition composition is provided in the ignition chamber, the igniter is configured to ignite the ignition composition and generate an inflation gas, and the end cover is further configured to be plastically deformed under effect of a pressure of the inflation gas, so as to increase a volume of the ignition chamber;
• wherein the end cover comprises a connection ring and a deformable plate which are integrally arranged, the connection ring is fixedly arranged on an inner side wall of the ignition box, the deformable plate blocks the open end, the at least one flow-through hole is formed in the deformable plate, and the deformable plate is configured to be plastically deformed in a direction away from the closed end under the effect of the pressure of the inflation gas.
