Abstract (en)
[origin: WO0233319A1] A hot melt glue gun comprising a main housing (5) having a glue stick accommodating bore (8) extending therethrough and terminating in a dispensing nozzle (9) through which melted glue is dispensed. A catalytic combustion element (16) is located in a combustion chamber (15) for raising the temperature of the main housing (5) to an appropriate temperature for melting the glue stick. Fuel gas is supplied to the catalytic combustion element (16) through a fuel gas valve (20) having a spindle (40) extending therefrom. A piezo electric ignition unit (27) generates an EMF for generating a spark across a pair of electrodes (25) in the combustion chamber (15) for igniting the fuel gas to initially burn with flame combustion to raise the temperature of the catalytic element (16) to its ignition temperature. An operating member (51) and an integral camming member (52) are slideable in the direction of the arrow D from an inoperative state to an operative state for sequentially operating the fuel gas valve (20) from a closed to an open state, and then the piezo electric ignition unit (27) for igniting the fuel gas in the combustion chamber (15). An idle camming surface (55) of the camming member (52) engages a cam follower (53) of the spindle (40) of the fuel gas valve (20) with the fuel gas valve (20) in the closed state, and an operating camming surface (59) engages the cam follower (53) with the fuel gas valve (20) in the open state.
