ABSTRACT:
A jet type gas burner includes a gas supply device, a control device, a piezo-electric device, a return device, a burning device and a housing. A base of the gas supply device is connected to a gas container such that the gas may pass into the base. An adjust rod of the control device is disposed in a hole of the base for controlling the amount of gas flow into the base, and its displacement may be controlled by means of a control knob. The gas enters an extension tube of the gas supply device through a relay seat and a return tube of the control device and is ejected through a jet gas nozzle into a mixing chamber of the burning device to mix with drawn-in air. The mixture is ejected through a nozzle and a plurality of auxiliary flame holes. By means of pressing a button on the gas burner, the piezo-electric device causes sparks to be generated by a conductive needle adjacent the nozzle to ignite the mixture of gas and air, and the flames are emitted from the nozzle as well as the flame holes. The auxiliary flames are provided to heat the return tube to promote gasification so as to enhance the burning effects and to prevent waste of fuel.
