[0045] The implementation principle of a portable ignition gun in an embodiment of the present application is as follows:

[0046] During use, the operator removes the first end cap 6 from the fire outlet 21 through threads, and then fixes it on the top of the gun body 2 by using the first magnet 71 and the second magnet 72. Then the gun head 1 is fixed on the gun body 2 through threads. At this time, the fire outlet 21 is internally communicated with the gun head 1. Then the operator presses the control button 43. While the control button 43 controls the start of the electronic igniter 42, the electric valve 231 is opened. The combustible gas in the gas storage cavity 22 flows out through the air outlet pipe 23 under the action of the air pressure in the gas storage cavity 22. When flowing through the fire outlet 21, it is ignited by the electric spark generated by the electronic igniter 42, and the flame sprays out through the gun head 1 along the air flow. The flame will burn the oxygen inside the gun head 1, creating a negative pressure inside the gun head 1, and the outside air flows into the inlet hole through the inlet hole to supplement oxygen for the flame combustion.

[0047] After use, the operator releases the control button 43, and both the electronic igniter 42 and the electric valve 231 are closed. After the gun head 1 cools down, the operator removes the gun head 1 from the gun body 2 through threads, then cleans the gun head 1, then wipes the fire outlet 21 of the gun body 2, and finally covers the first end cap 6 on the opening of the fire outlet 21 through threads, and the ignition gun can be stored and carried.

[0048] When the electric energy inside the battery 41 is exhausted, the operator can charge the battery 41 through the USB structure.

[0049] When the combustible gas in the gas storage cavity 22 is exhausted, the operator can remove the second end cap 56 by means of threads, and then use an inflatable tank to press the valve plug 55, so that the valve plug 55 compresses the spring 54 and moves away from the valve plate 52, thereby connecting the inflation hole 521. Then, under the pressure inside the inflatable tank, the combustible gas enters the gas storage cavity 22 through the gas filling pipe 51. After the combustible gas is replenished, the operator fixes the second end cap 56 on the gas filling pipe 51 by means of threads to avoid accidentally touching the valve plug 55 and causing leakage of the combustible gas.

[0050] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
