Description

Explosion Proof Portable Gas Burner {.}

The present invention relates to an explosion-proof portable gas burner, and more particularly, to a explosion-proof portable gas burner whose structure is improved to prevent explosion of the gas cylinder mounted on the portable gas burner.

In general, a portable gas burner is equipped with a gas cylinder in which combustion gas such as LPG is stored. The gas cylinder is closed by installing a bottom plate at one end of a hollow cylindrical body, and a nozzle is formed at the other end of the body. The outlet of the nozzle is normally closed, but when the nozzle is inserted into the gas cylinder under pressure from the outside, the outlet of the nozzle is opened to allow the combustion gas inside the gas cylinder to flow out.

In the portable gas burner, when the nozzle is compressed by the combustion tube inlet by pushing the bottom plate of the gas cylinder, the combustion gas in the gas cylinder enters the combustion section via the combustion tube and combustion starts. In addition, when the pressure applied to the bottom plate of the gas cylinder is released and the nozzle is separated from the combustion tube, the outflow of the combustion gas in the gas cylinder is stopped and the combustion of the portable gas burner is stopped.
