A tubeless hand-held tool that controls gas combustion to form a cylindrical flame for heating and welding, also known as a hand-held flamethrower (butane is generally used as gas).

Second, the structure

Pocket flamethrower is divided into two main structures: air storage chamber and surge chamber, and middle and high-grade products also have ignition structure.

Air storage chamber: also known as the name box, contains gas, usually butane, which transports gas for the buffer chamber structure of the tool.

Buffer chamber: This structure is the main structure of hand-held flamethrower. It receives gas from the gas storage chamber, and then ejects the gas from the muzzle through a series of steps such as filtration, pressure regulation and current conversion.

Third, the working principle

By adjusting the pressure and changing the flow rate, the gas is ejected from the muzzle and ignited to form a high-temperature cylindrical flame for heating and welding.

Fourth, specifications

Structurally, there are two kinds of hand-held flamethrowers, one is an integrated hand-held flamethrower with an air box, and the other is a separate flamethrower head with an air box.

1) air box integrated hand-held flamethrower: easy to carry, generally smaller and lighter than the separate type.

2) Pocket flamethrower head with gas tank separation: it needs to be connected with a cassette gas cylinder, which has a large weight and volume, but has a large gas storage capacity and a long continuous use time.

Verb (abbreviation of verb) characteristics

Compared with welding guns and other tools that need to transport gas by pipeline, portable flamethrower has the advantages of integrated gas box and wireless portability. However, because portable flamethrowers rely on oxygen combustion and gas pressure in the air, the flame temperature of commonly used portable flamethrowers generally does not exceed 1400 degrees.

Windproof lighters can be said to be the predecessor of portable flamethrowers. The middle and high-grade portable flamethrower has been innovated and expanded in the following points, which has improved the use value and expanded the use, and can be competent for more demanding working environments.

1. air filter structure: reduce the blocking probability, ensure the service performance of tools and improve the service life.

2. Pressure regulating structure: the gas flow is optimally controlled, and the flame size and temperature are higher.

3. Heat insulation structure: reduce heat conduction effect and ensure the stability of pressure regulating structure and gas flow.

Use of intransitive verbs

1) industrial application: ▲ welding ▲ jewelry and glasses processing ▲ plumbing maintenance ▲ loose and corroded metal screw sets.

▲ kitchen baking tools ▲ laboratory heating research ▲ factory equipment maintenance ▲ outdoor ignition 2) kitchen utensils use

The flamethrower using pure butane gas can be directly used as a barbecue tool to process ingredients, and the combustion products are water and carbon dioxide, which is clean and environmentally friendly.
