Working principle：
The safe flame gun of this hand-held using replaceable built-in gas tank be used as gas source, it is easy to carry, installation gas tank when, by gas
Circle 43 is backed out under the gas pitcher cover of 4 lower end of tank cover, and gas tank is put under gas pitcher cover in circle 43, is held circle 43 under gas pitcher cover and is put gas tank
Enter in gas pitcher cover 4, firmly screws upwards；In screwing operations, the position of gas tank rises, and pushes up piston rod 26, makes thimble
24 bursting gas tanks realize the conducting between gas tank and core assembly.
After gas source is installed, it can light a fire and use, before igniting, valve be opened by adjusting knob 5, is made in gas tank
Combustion gas flow to nozzle component 3 through valve body 2.This flame gun uses electronic ignition, and the electronic switch 71 of electronic ignition device is fixed
In in shell 1, and the igniter head for matching with trigger 6, and being fixed in nozzle component 3 then passes through conducting wire 72 and electronic switch 71
It is connected.When igniting, trigger 6 only need to be pressed inward against, is that trigger 6 inside contracts electronic switch 71 is made to be powered, electric signal makes at igniter head
Electric spark is generated to ignite combustion gas.After the completion of igniting, trigger 6 is unclamped, trigger 6 can automatically reset under the action of the spring.
This flame gun also sets up to guarantee the safety used by safety button 81, safety plate 82 and relief spring
The safety locking motion 8 of 83 compositions, safety button 81 are stretched out outside shell 1, and safety plate 82 is located at the motion track of 6 internal pressure of trigger
It is interior, due to the limitation of safety plate 82, make the trigger 6 of flame gun in a latched condition (insurance does not release) can not internal pressure igniting；Cause
This needs to pin safety button 81 and does not put before ignition, so that safety plate 82 is moved away the motion track of trigger 6 to release and protect
Danger.After the completion of igniting, safety plate 82 resets under the action of relief spring 83, is moved again to shape in the motion track of trigger 6
At insurance；The setting of safety locking motion 8 can guarantee the safety used, avoid the security risk caused by maloperation.
After the completion of igniting, it can according to need through adjusting knob 5 and adjust flame size, when tuning up flame, valve rod 21
It moves up, valve port open degree increases, on the contrary, valve rod 21 moves down when turning flame down, valve port open degree reduces.It has used
Valve port closing only need to can be made fiery extinguishing by adjusting knob 5 by Bi Hou.
Highly preferred embodiment of the present invention has illustrated, and the various change or remodeling made by those of ordinary skill in the art are not
It can depart from the scope of the present invention.
