The structure of a flamethrower

The handheld spray gun is divided into two main structures: a gas storage chamber and a pressure regulating chamber. Mid to high end products also have an ignition structure.

Gas storage chamber: also known as a gas tank, containing gas, usually composed of butane, which is used to transport gas to the pressure regulating chamber structure of the tool.

Pressure regulating chamber: This structure is the main structure of the handheld spray gun. It receives gas from the gas storage chamber, and after a series of steps such as filtering, pressure regulation, and flow transformation, the gas is sprayed out of the muzzle.
