Description

Technical Field

[0001] This utility model belongs to the field of gas ignition guns, and specifically relates to a gas ignition gun. Background Technology

[0002] Existing ignition guns typically include a gun body, a gun barrel, and a piezoelectric component and a vent valve installed in the gun body for ignition. The gun body has a gas chamber for storing liquefied combustible gas, and the vent valve is located on the upper part of the gas chamber. The gun body also has a button assembly for simultaneously controlling the opening and closing of the vent valve and the ignition process of the piezoelectric component. The gun barrel has an outlet pipe, one end of which is connected to the vent valve, and the other end is located at the nozzle of the gun barrel and is equipped with a burner. The ignition wire and circuit wire of the piezoelectric component extend to the gun barrel to generate an electric spark to ignite the combustible gas output from the burner.

[0003] Chinese Patent No. CN216203501U discloses a handheld high-energy ignition gun, including an ignition gun housing. One end of the housing is connected to a connecting seat, and the other end is connected to a gas inlet. An ignition gun barrel is connected to the outer surface of the connecting seat. A sealing sleeve is connected to the connection between the ignition gun barrel and the connecting seat, and a stop mechanism is connected between the barrel and the connecting seat. An ignition switch is connected to the top of the housing, and a protective mechanism is connected to the upper surface of the housing near the ignition switch. A gas box is provided in the housing, and a gas supply pipe is connected to the output end of the gas box. This handheld high-energy ignition gun can be stopped and locked at the connection point to prevent the barrel from bending and being damaged. Furthermore, the switch can be covered when the ignition gun is not in use to prevent accidental ignition.

[0004] As can be seen from the above structure, the barrel length of the existing ignition gun is fixed and cannot be adjusted, which is not convenient for short-distance or long-distance fire-starting needs in different scenarios and poses a certain danger. Since the existing long barrel is fixed to the ignition gun body, the ignition gun cannot be stored when not in use, making it inconvenient to carry and very cumbersome. Utility Model Content

[0021] Example

[0022] refer to Figures 1 to 4This embodiment of a gas-fired ignition gun includes a first outer shell 1 and a second outer shell 2. Both the first outer shell 1 and the second outer shell 2 have an internal gas tank 5 and a piezoelectric igniter 6. One end of each of the first outer shell 1 and the second outer shell 2 has a telescopic tube 3, and the other end of the telescopic tube 3 is fixedly connected to a flame head 4. The surfaces of the first outer shell 1 and the second outer shell 2 have operating grooves 18, and the operating grooves 18 have internal operating triggers 19. The telescopic tube 3 includes an outer sleeve 31, with a telescopic inner tube 32 threadedly connected to the inside of the outer sleeve 31. The outer side of the telescopic inner tube 32 has a telescopic external thread 34, and the inner side of the outer sleeve 31 has a telescopic internal thread 33. The telescopic internal thread 33 and the telescopic external thread 34 are threadedly connected to each other. The gas tank 5 and the piezoelectric igniter 6 are connected to the flame head 4 via a hose and a wire.

[0023] refer to Figure 2 and Figure 4 One end of the outer sleeve 31 is rotatably connected to the mounting tube 7. The outer surface of the mounting tube 7 is provided with mounting holes 8. One end of the first outer shell 1 and the second outer shell 2 are fixedly connected to the mounting shell 9. The inner side of the mounting shell 9 is fixedly connected to the mounting block 10. The mounting block 10 is inserted into the mounting hole 8. By placing the mounting tube 7 inside the mounting shell 9 and then inserting the first outer shell 1 and the second outer shell 2, the mounting shell 9 will also close after the first outer shell 1 and the second outer shell 2 are inserted, so that the mounting block 10 is inserted into the mounting hole 8. After the mounting block 10 and the mounting hole 8 are engaged, the telescopic tube 3 can be installed.

[0024] refer to Figure 4 Both the mounting tube 7 and the telescopic inner tube 32 are fixedly connected to mounting rods 24. The inner side of the mounting rod 24 inside the mounting tube 7 is fixedly connected to a limiting rod 26. The surface of the mounting rod 24 inside the telescopic inner tube 32 is provided with a limiting hole 25. The limiting hole 25 and the limiting rod 26 are interlocked. The limiting rod 26 and the limiting hole 25 can limit the telescopic inner tube 32 during use, preventing the telescopic inner tube 32 from rotating when the outer sleeve 31 is rotated, thus preventing the adjustment from being impossible.

[0025] refer to Figure 2 and Figure 3 The outer surface of the mounting shell 9 is fitted with a reinforcing cylinder 12. The inner side of the reinforcing cylinder 12 is provided with an insertion groove 13. The lower end of the mounting shell 9 is fixedly connected with an insertion block 11. The insertion block 11 and the insertion groove 13 are inserted into each other. After the telescopic tube 3 is installed, the reinforcing cylinder 12 is fitted with the mounting shell 9. During the fitting, the insertion groove 13 and the insertion block 11 are inserted into each other. This can increase the installation effect of the mounting shell 9 during use and prevent the mounting shell 9 from loosening and cracking.

[0026] refer to Figure 2 and Figure 3A first fitting edge 14 is fixedly connected to one side of the first outer shell 1, and a second fitting edge 15 is fixedly connected to one side of the second outer shell 2. The first fitting edge 14 and the second fitting edge 15 are interlocked with each other. The first outer shell 1 and the second outer shell 2 are interlocked with each other. A mounting post 17 is fixedly connected inside the first outer shell 1, and a mounting sleeve 16 is fixedly connected inside the second outer shell 2. The mounting post 17 and the mounting sleeve 16 are interlocked with each other. By interlocking the mounting post 17 and the mounting sleeve 16 of the first outer shell 1 and the second outer shell 2, the first outer shell 1 and the second outer shell 2 can be installed after the interlocking is completed. Under the action of the first fitting edge 14 and the second fitting edge 15, the situation where there are gaps at the interlocking point, which would cause dust to enter the interior of the first outer shell 1 and the second outer shell 2 can be avoided.

[0027] refer to Figure 1 The first outer shell 1 and the second outer shell 2 are provided with an adjustment knob 20 at their upper ends, and a gas filling port 21 is provided on the other side of the first outer shell 1 and the second outer shell 2. A locking block 22 is provided on the surface of the second outer shell 2, and an observation port 23 is provided at the upper end of the first outer shell 1 and the second outer shell 2. The size of the flame source can be adjusted by the adjustment knob 20. The gas filling port 21 can be used to fill the gas tank 5 without disassembling the first outer shell 1 and the second outer shell 2. At the same time, the locking block 22 can lock the operating trigger 19 to prevent accidental ignition. The observation port 23 can be used to observe the liquid volume inside the gas tank 5. All of these structures are conventional structures of existing igniters.

[0028] Operating principle and advantages: First, the mounting pins 17 of the first outer shell 1 and the second outer shell 2 are inserted into the mounting sleeve 16. After insertion, the first outer shell 1 and the second outer shell 2 can be installed. The first contact edge 14 and the second contact edge 15 prevent gaps at the insertion point from allowing dust to enter the interior of the first outer shell 1 and the second outer shell 2. During installation, the mounting tube 7 is placed inside the mounting shell 9, and then the first outer shell 1 and the second outer shell 2 are inserted. After insertion, the mounting shell 9 closes, allowing the mounting block 10 to engage with the mounting hole 8. Once the mounting block 10 and the mounting hole 8 are engaged, the telescopic tube 3 can be installed. Thus, after the first outer shell 1 and the second outer shell 2 are installed... The device allows for adjustment of the flame size via the adjustment knob 20. The gas filling port 21 allows for gas filling of the gas tank 5 without disassembling the first outer shell 1 and the second outer shell 2. Simultaneously, the locking block 22 locks the operating trigger 19 to prevent accidental ignition. The observation port 23 allows for observation of the liquid volume inside the gas tank 5. All structures are conventional structures for existing igniters. When adjustment of the telescopic tube 3 is required during use, rotating the outer sleeve rod allows the telescopic inner tube 32 to move out of the outer sleeve rod under the action of the telescopic inner thread 33 and the telescopic outer thread 34. This increases the length of the telescopic tube 3 when the telescopic inner tube 32 moves out of the outer sleeve 31, thus allowing for flexible adjustment of the ignition gun length according to actual usage needs, improving ease of use and flexibility.
