Patent ID: 7850446

Claim:
A hand-held gas combustion apparatus, comprises: a gas storing tank, an opening is provided on a tank top provided at a top end of a tank body, a tank bottom is provided at the bottom end of the tank body and is provided with a gas filling nozzle; a gas discharging device, a discharging nozzle is provided on the opening for controlling the supplying/ceasing of combustion gas, the discharging nozzle is connected to a gas conveying tube and the other end thereof is connecting to an ejecting nozzle; a housing composed by two cover members connecting together, so a housing tenon and a button hole are respectively formed on the two lateral ends, and a connecting ring provided at the bottom end is connected to the tank top of the gas storing tank, a polygonal positioning hole is axially provided on the housing tenon and the top end and the bottom end of the housing tenon is respectively and in parallel provided with a linear slot; an ignition system, a piezoelectric device is fastened in the housing and the rear end of the piezoelectric device is connected to a button extruding out of the button hole, the button is extrudingly provided with a pushing rod that can be served to actuate a discharging sheet so the discharging nozzle is operated to supply gas, a conductive wire is extended from the piezoelectric device and is received in one of the linear slots, and the metal exposed portion of the conductive wire is fastened in the positioning hole, and one end of an electricity-guiding wire defined as a connecting end is connected to a metal electricity-guiding section of the piezoelectric device, and the other end thereof defined as a contacting end is extended into the other linear slot; a flame device, a polygonal tube end defined at a rear end of a mixing tube is clamped in the positioning hole so as to be in contact with the conductive wire, and the tube end is served to let the ejecting nozzle being mounted into, at least one air intake hole is provided at the lateral side of the mixing tube, and the front end of the mixing tube is provided with a flame nozzle, and a metal sleeve tube is connected to a connecting ring then the connecting ring is connected to the housing tenon, so the contacting end of the electricity-guiding wire is in contact with the rear end of the sleeve tube, and the flame nozzle is provided in front of the sleeve tube, a small distance is generated between an inner folding edge provided at the front end of the sleeve tube and the flame nozzle for generating a high-voltage static electricity spark which is served to ignite the mixed combustion gas ejected from the flame nozzle.
