ABSTRACT:
The portable burning device includes a gas tank, a coupling seat, a piezo-electric means, a control means, a gas release means, an outer tube unit and a shell. In use, a knob is turned in a counter-clockwise direction to cause a projection of an adjusting rod to retreat so as to be separated from a neck hole of a shaft such that fuel gas may be induced via an intake tube into a gas duct. The pressure of the fuel gas is regulated by a pressure regulating means to accelerate flow of the fuel gas into a shaft hole. The fuel gas then passes through the neck hole and a shaft opening and is ejected via a gas nozzle. The current of gas thus generated draws in ambient air via an air vent into a mixing tube. The mixture of gas and air flows through a gear seat and is ejected via a central gear hole and a plurality of gear ducts defined between adjacent teeth of a gear. By pressing a push button at this point, electrostatic sparks generated by the piezo-electric means will ignite the mixture.
