By setting the sealing plug 2, the burner is sealed. By setting the pressure relief hole 301, the pressure relief effect is achieved. By setting the sealing cover 302 and the sealing rubber 303, the sealing performance is improved. By setting the reset spring 305, when the reset spring 305 keeps the original length, it is ensured that the sealing cover 302 is engaged with the pressure relief port and the telescopic rod 304 is contracted. When the elasticity of the reset spring 305 is restored, the sealing cover 302 and the telescopic rod 304 are driven to reset. By setting the telescopic rod 304, the sealing cover 302 is ensured to move stably, and a threaded groove is provided at one end of the telescopic rod 304, which is convenient for disassembly of the sealing cover 302 and replacement of the reset spring 305. By setting the exhaust fan 308, the pressure relief speed is improved.

[0022] The ignition assembly 1 comprises an ignition device body 101 , and a control panel 102 is connected to the ignition device body 101 , and a conduit 103 is snap-connected to the outside of the ignition device body 101 .

[0023] One end of the conduit 103 is snap-connected with the ignition gun 104 , and the outside of the conduit 103 is sleeved with the sealing plug 2 , and the ignition gun 104 is snap-connected with the sealing plug 2 .

[0024] The pressure stabilizing assembly 4 includes a booster pump 401, and a second conduit 402 is connected to the front of the booster pump 401. The second conduit 402 is sleeved with the ignition device body 101. By providing the booster pump 401, it is convenient to pressurize the gas in the burner.

[0025] One end of the second conduit 402 is snap-connected with the air inlet 403, and the air inlet 403 is opened in the sealing plug 2, the boost pump 401 is installed in the ignition device body 101, and the ignition device body 101 is fixedly connected with a display 405, and the sealing plug 2 is snap-connected with a sealing air bag 404 on the outside.

When the pressure is too low, the booster pump 401 is started, so that the gas generated by the booster pump 401 is injected into the burner through the conduit 2 402 and the air inlet 403, thereby enhancing the pressure in the burner and keeping the internal pressure of the burner stable. When the pressure displayed on the display 405 is too high, the internal gas pushes the sealing cover 302 to separate from the pressure relief port, and at the same time, the reset spring 305 is stretched to drive the extension spring 305 to extend. The retractable rod 304 is extended to discharge the gas inside the burner, so that the pressure relief port generates airflow, which drives the exhaust fan 308 to rotate, thereby accelerating the discharge of internal gas. When the gas inside the burner drops to a stable value, the elasticity of the return spring 305 is restored, driving the sealing cover 302 to move, so that the sealing cover 302 and the pressure relief port are engaged, and the sealing rubber 303 is squeezed to enhance the seal, thereby stabilizing the internal pressure, reducing the occurrence of danger, and causing the telescopic rod 304 to retract. Secondly, the ignition gun 104 is started through the control panel 102, so that the ignition gun 104 ignites the ignition burner, thereby completing the ignition of the gas industrial furnace.
