The slider 34 is made of low-friction engineering plastic, which smoothly mates with the metal surface of the slide rail 31, allowing for smooth movement of the handle 32. By sliding the handle 32, the user can easily adjust the operating position to adapt to different working scenarios.The fixed tube 41 is externally fixedly connected to the inside of the gun body shell 1, and internally fixedly connected to the outside of the flame tube 44. The left end of the flame tube 44 is fixedly connected to the inside of the high-pressure pulse igniter 43, and the right end of the flame tube 44 is fixedly connected to the outside of the fuel supply pipe 24. This connection structure ensures that fuel can be smoothly delivered from the fuel storage assembly 2 to the ignition assembly 4, and reliably ignited under the action of the high-pressure pulse igniter 43. The fixed tube 41 provides a stable support for the flame tube 44, while its external heat dissipation holes 42 help dissipate the heat generated during ignition, ensuring the safe and stable operation of the entire ignition system.

[0028] Working principle: When using a dual-purpose spray and drip backpack electric igniter, the fuel tank 21 is carried on the body via the shoulder strap 23 in the fuel storage assembly 2. The ergonomic flexible support 22 on the front of the fuel tank 21 conforms to the human body, improving carrying comfort. Fuel transfer is then prepared; the fuel in the fuel tank 21 is transferred through the fuel supply pipe 24. The end of the fuel supply pipe 24 is connected to the inside of the flamethrower tube 44, which is connected to the fixing pipe 41. The fixing pipe 41 is externally fixed inside the gun body shell 1. The left end of the flamethrower tube 44 is connected to the high-voltage pulse igniter 43, and the right end is connected to the fuel supply pipe 24, forming... In the fuel transmission channel, when flame-throwing operation is required, the user holds the handle 52 in the lifting support assembly 5. The anti-slip indentation 53 at the bottom of the handle 52 increases the grip stability. By pulling the trigger 33 inside the handle 32 in the modular assembly 3, the ignition assembly 4 is triggered to work. At this time, the high-pressure pulse igniter 43 inside the fixed tube 41 generates a high-pressure pulse, which ignites the fuel delivered to the flame-throwing tube 44 through the oil supply pipe 24. The fuel is sprayed out from the flame nozzle 45 and burns, realizing the flame-throwing function. The heat dissipation holes 42 opened on the outside of the fixed tube 41 can effectively dissipate the heat generated during the ignition process and ensure the safe operation of the equipment.

[0029] For fuel dripping, the user can slide the fuel reservoir 46 within the slide groove 37 via the slide bar 39. The bottom of the slide bar 39 is connected to the fuel reservoir 46. A limiting plate 38 is provided on the left side of the slide groove 37 to prevent the slide bar 39 from sliding out. The fuel in the fuel reservoir 46 is transferred through the fuel dripping pipe 47. The fuel dripping pipe 47 is externally slidably connected to the inside of the clamping ring 55. The clamping ring 55 is connected to the bottom of the gun body shell 1 via the connecting rod 54 to ensure the stability of the fuel dripping pipe 47. The fuel atomizing device 48 at the end of the fuel dripping pipe 47 atomizes the fuel and drips it out, thus realizing the fuel dripping function. During operation, the lifting ring 51 makes it easy for the user to lift or move the equipment. The support leg 56 at the bottom of the gun body shell 1 can be unscrewed as needed to support the equipment. The counterweight block 61 in the counterweight assembly 6 is fixed to the top right side of the gun body shell 1 by screws 63, which can adjust the center of gravity of the equipment to make the operation more stable and effortless. The slider 34 in the modular assembly 3 slides in the slide rail 31 and can be used to remove the handle 32 for easy storage. The fixing ring 35 and bolts and nuts 36 are used to fix the flame tube 44 and other components to ensure the stability of the equipment structure.
