Therefore contrast prior art needs two steps of operations to deflate earlier and then ignite, the utility model discloses a simultaneously, thereby the event can be avoided the gas to be released and can not utilize and cause the condition of waste and pollution.

The principle of the flame gun is as follows: sleeve 2 is included first and sleeve 2 serves to protect barrel 21 and also to isolate barrel 21 from the user, thereby preventing the user from being burned. Meanwhile, the sleeve 2 is arranged at the front end of the shell 1 and is internally provided with a gun tube 21, and the gun tube 21 is arranged at the front end of the valve body 11.

And the igniter 16 is provided with an electrically conductive wire which is disposed along the outside of the valve body 11 with one end of the electrically conductive wire penetrating the barrel 21 and generating an electric spark in the barrel 21. Thus, when the trigger 13 presses the igniter 16, the conductive wire may generate an electric spark within the barrel 21, thereby igniting the gas within the barrel 21.

And the bottom of the valve body 11 is provided with a gas inlet 118 for connecting with a gas tank, and the valve body 11 is provided with a first passage 119a for communicating the gas inlet 118 with the gun barrel 21, and the first valve 18 obstructs the passage 119a so as to prevent the gas from flowing through.

In actual use, the trigger 13 is pressed inwardly by the user to open the first valve 18 and supply gas to the barrel 21, whereupon the igniter 16 is pressed to generate an electric spark at the leading end of the conductive wire and ignite the gas in the barrel 21.

As shown in fig. 2, it can be seen that the housing 1 is provided with a second passage 119b in the valve body 11 in an inclined manner, which communicates with the first passage 119 a. While the first valve 18 includes a spool 181 and a pushrod 182, wherein the spool 181 is positioned in the first passage 119a and prevents the flow of gas, and the pushrod 182 is positioned in the second passage 119 b. And the lower side of the rear end of the push rod 182 abuts against the upper end of the valve core 181. Wherein, the prevention of the gas circulation is realized by blocking the circulation of the channel through a sealing ring sleeved outside the valve core 181.

Therefore, in actual use, the push rod 182 is moved backward by pressing the trigger 13 to press the valve element 181 downward, so that the gasket is moved downward to prevent the gas from flowing therethrough. Meanwhile, the valve core 181 and the push rod 182 are reset by springs, and when the trigger 13 is not applied with external force and is not limited, the valve core 181 and the push rod 182 can be reset by the springs.

The igniter 16 is abutted against one side of the valve body 11, wherein in a specific connection structure, firstly, a placing groove 115 for placing the igniter 16 is formed in one side of the valve body 11, and a limit convex plate 116 is arranged on the periphery of the placing groove 115, so that the limit is added to the bottom of the igniter 16, and the igniter cannot move up and down or left and right.

Meanwhile, for the convenience of people, namely, the trigger 13 does not need to be pressed for a long time so as to ensure the opening of the first valve 18, a locking structure is arranged on the trigger 13 and is reset through a spring.
