Description

Technical Field

[0001] This utility model relates to the field of flame-throwing device technology, and specifically to a flame-throwing device. Background Technology

[0002] Flamethrower devices can be divided into handheld flamethrowers and airborne flamethrowers depending on the owner. Handheld flamethrowers require manual control by the user, posing certain safety hazards when used in complex environments such as mountainous areas and high altitudes. Airborne flamethrowers, on the other hand, are fixed to a mobile device, and the flame direction changes with the movement of the mobile device. Once the mobile device stops moving, the flame direction of the airborne flamethrower cannot be finely adjusted, resulting in problems such as insufficient precision in flame direction control and poor stability. Utility Model Content
