    • DETAILED DESCRIPTION OF EMBODIMENTS
  • FIGS. 1 to 4 show a gas-fueled appliance in the form of a gluing gun for providing thermoplastic glue according to a first embodiment of the present invention. Referring to FIG. 1, the gas-fueled appliance includes a shell 10 consisting of two halves. The shell 10 includes a barrel 11 and a handle 12. Referring to FIG. 2, each half of the shell 11 includes a crescent partition 15 formed on an internal side. As the halves of the shell 11 are assembled, the crescent partitions 15 make an annular partition for separating the barrel 11 from the handle 12. A recess 16 is defined in the edge of each half of the shell 11. As the halves of the shell 11 are assembled, the recesses 16 make an aperture through which a trigger 33 extends to the exterior from the interior of the shell 11. Each half of the shell 11 defines a slot 17. One half of the shell 11 defines an aperture 19.
  • Referring to FIG. 2, the gas-fueled appliance includes a can 20 put in the handle 12, a burner 30 put in the barrel 11, and a transmitter 40 for transmitting gas to the burner 30 from the can 20. The can 20 includes an aperture 21 defined therein.
  • The burner 30 includes a nozzle 31 formed at an end and an aperture 36 defined in an opposite end. A holder 32 is formed on an internal side of one half of the shell 11 opposite to the nozzle 31. The holder 32 defines an aperture 38 aligned with the aperture 36 so that thermoplastic glue (not shown) can be fed to the burner 30 from the holder 32. A lever 39 includes an end pivotally connected with the holder 32 and an opposite end pivotally connected with the trigger 33. Thus, the holder 32 is movable through pulling the trigger 33.
  • The gas-fueled appliance includes an igniter 34 located near the burner 30. An electrode (not shown) of the igniter 34 is put in the burner 30. The gas-fueled appliance includes a button 35 for actuating the igniter 34 in order to ignite the gas in the burner 30. The button 35 extends to the exterior from the interior of the shell 11 through the aperture 19.
  • The transmitter 40 includes a valve 43 connected with the tank 20, a flow rate regulator 42 connected with the valve 43, and a pipe 41 leading to the burner 30 from the valve 43.
