Portable gas furnace

The utility model relates to a be suitable for the portable gas furnace of outdoor use. It includes furnace body, gas holder, on -off control valve and furnace end, this on -off control valve includes valve body, flow control valve core, selectively opens or cut out this inlet channel so that the air inlet housing communicates the safe switching device that perhaps ends with the decompression chamber. The utility model has the advantages of as follows: 1, can be so that the gas of stablizing atmospheric pressure can be exported in the gas outlet through setting up decompression chamber and pressure adjustment assembly to improve culinary art quality and factor of safety, 2, in order to realize selectively opening or closing this inlet channel, when the furnace body high temperature, can close inlet channel through safety switching device when the gas holder internal gas pressure is higher through setting up safe switching device, reduce the accident coefficient of blasting, 3, the material of gas holder is al
