ABSTRACT:
An improved gas pistol with reverse flow heating device including a base, a support device, a piezo electric device, an air control device, a reverse flow heating device, an ejection device and an outer tube. In use, an insert ring is coupled to a gas container so that a conical pin in a neck ring urges against a gas valve of the gas container to release the gas, which flows via an inverted-L shaped hole at one side of the conical pin into a neck channel into a sleeve. By turning a control rod to adjust the flow of gas and to cause it to pass through an insert mount, a heating tube and a nut hole into a securing nut, the gas is vaporized and then passed through a relay tube to be ejected through a gas nozzle. At the instant when the gas is ejected, an air adjustment knob may be turned to adjust the amount of induced air to help combustion. Gas and air are mixed in a mixing tube, and the mixture is pushed to a flame nozzle and ejected through a jet hole and a plurality of primary flame holes. By pressing a push button and a piezo electric element, the static sparks generated by the electric wire may be transmitted to the jet hole and the flame holes to ignite the mixture.
