The spark plug boosts the voltage of $38 charged at the end portion of the handle portion 12a to a high voltage, and a spark is generated by discharging the high voltage. The ignition device 37 ignites the mixed gas by generating a spark in the combustion chamber 19 where the mixed gas is generated: 'and combusts the mixed body 4 to generate a pressurized combustion gas in the combustion to 19. The ignition device 37 is driven via the control circuit board 41 in accordance with the ignition switch 4A that operates by the trigger 39 provided at the base of the handle portion 12a. On the other hand, in the present embodiment, as shown in the second and second figures, the combustion chamber 19 is adjacent to the fuel supply control device "with 10 201210760 supplied with gas fuel to the combustion chamber 19. Therefore, the fuel supply control device is evacuated. The enterprise door, the distance of the fuel passage, the time and the door of the main combustion chamber 丨9, can quickly supply the fuel, and can be shortened to the point of manufacture: the heat member 47 is disposed at The combustion chamber 19 is disposed between the fuel supply control main casing & thermal structure #47 so as to form a gap therebetween, so that the air layer portion 48 is formed in the fuel supply control device 32 and the combustion chamber j9. The firing chamber 19^' (4) is in the fuel supply control air layer: 4.8 In addition to the heat insulating member 47, it is also provided with the "burning", so even though the fuel supply control device 32 is configured to be a fuel supply control device 32 It is difficult to accept the radiant heat from the sputum, and the liquefied gas fuel is suppressed from being vaporized in the fuel supply control device. As shown in the second paragraph, the gas fuel supplied from the fuel supply control device 32 is introduced. Practice $ ^ to burn the room above the 19 The supply pipe 31 is connected to the connecting portion 3 which is disposed above, and burned to 19. The heat transfer coefficient is lower than that of the connecting portion 3. The lower material/supply...1 is made of metal, and η, 斤For example, the connection portion 30 疋I belongs to the crucible, and the gas supply tube is made of rubber or fluoro rubber. The heat supply is difficult to guide the gas supply tube with low thermal coefficient: this is: the fuel supply control device 32 is arranged adjacent to the combustion chamber (7). The heat that is burned to 19 is difficult to pass through the tile neck. Ψ The supply, the α-tube 3丨 is directed to the fuel supply, and the liquefied gas fuel is suppressed from being supplied to the fuel supply control device. "The feeling of the flexible member such as rubber or rubber, such as the rubber, can make the curved portion smooth. Therefore, the pipe resistance can be suppressed, and the fuel can be quickly supplied at 11 201210760. In the present embodiment, as shown in Fig. 3, the blocking wall 45 for blocking heat transfer is provided in the gas tube accommodating portion 43 and the combustion chamber in which the gas tube 33 is housed. Between 19, the gas pipe housing portion 43 is ignited by the partition wall 45. The firing chambers 19 are separated. Therefore, the heat of the combustion chamber 19 is hard to be conducted to the gas tubes 33, and the gas tubes 33 are suppressed from being heated and the liquefied gas fuel is vaporized in the gas tubes 33. The air passage of the combustion chambers 19 is described in detail. The passage 24 communicating with the inside of the combustion chamber 19 is vented (discharged from the discharge port 49 of the main casing 11). At that time, the air (heat) of the combustion chamber 19 is as shown in Fig. 4B, and is also directed to the handle casing. The direction D of 12 flows. However, as shown in Fig. 4B, since the blocking wall blocks the flow of air (heat), the air (heat) does not flow into the gas tube accommodating portion 43 of the gas esing tube 33. The gas pipe 33 is extended in the upper and lower directions as indicated by the point chain (PIPE) of the cable 5 diagram. The air (heat) from the combustion chamber 19 flows in the direction toward the fuel container accommodating portion 42 along the gas pipe 33. In other words, the air (heat) from the combustion chamber 丨 9 is maneuvered beside the gas tube accommodating portion 43 partitioned by the blocking wall 45. Therefore, although the blocking wall 45 is provided, the temperature inside the gas tube throttling portion 43 cannot be prevented from rising slightly. Therefore, in the gas tube housing portion 43, as shown in Fig. 6 of the cross-sectional view of the gas tube 33, a heat discharge port 46 that communicates with the outside is formed. That is, although the gas tube accommodating portion 43 is formed by dividing the inner side of the main casing 11 by the blocking wall 45, a plurality of heat vents 46 are formed in the opening on the outer wall of the main casing 11 where the gas collecting portions 43 are formed. Therefore, the heat suffocating in the gas tube accommodating portion 43 can be discharged from the heat exhaust port 46 to the outside of the 201210760, and the gasification of the liquefied gas fuel can be suppressed by heating the gas tube 、 and the tube 33.

That is, the air flow path acts as a guide for the heat generated by the combustion chamber 19, and the heat transfer means uses the heat generated in the combustion chamber 19. The fuel container 34 is heated to reduce the temperature difference between the fuel container 34 and the fuel supply control device 32 and the gas pipe 33 located in the vicinity of the combustion to 19, thereby suppressing the pressure change caused by the U difference and vaporizing the liquefied gas fuel. As described above, according to the present embodiment, since the fuel supply control device 3 2 and the combustion officer are arranged adjacent to each other, the tube of the gas supply pipe 31 is disposed. The road is short. Further, since the curved portion of the gas supply pipe 31 is small and the curved portion is smoothly formed, the pipe resistance of the gas supply f 31 becomes small. Therefore, the fuel can be quickly supplied to the combustion chamber 19, and the time to the point can be shortened. Further, various means for suppressing vaporization of the liquefied gas fuel by the radiant heat of the combustion chamber 19 are included. Therefore, the example #' can avoid the problem that the flow rate in the fuel supply control device 32 cannot be accurately adjusted due to vaporization of the liquefied gas fuel. Further, in the above embodiment, although the fuel supply control device 设置 is provided in the handle housing 12 β, the present invention is not limited thereto. For example, the fuel supply control device 32 may be disposed on the combustion chamber 19 or may be powered. The control device 32 is mounted outside the body casing 11 side. Further, in the above embodiment, the gas pipe 33 is also provided in the handle casing 12, but the gas pipe 33 is not limited thereto, and the gas pipe 33 may be provided outside the hand casing 12 201210760. Further, in order to make it difficult for the gas tube 33 to receive radiant heat, the gas tube 33 itself may have a heat insulating effect or cover the gas tube 33 with a heat insulating material such as a heat insulating tape. Further, in the above-described embodiment, the air flow path from the combustion chamber 19 to the mass container accommodating portion 42 is a heat conduction means for accommodating heat generated in the combustion chamber 19 to the fuel container, but the present invention is not limited thereto. . For example, a metal piece extending from the combustion chamber 19 to the fuel container accommodating portion 42 may be used as a heat transfer hand &' and the heat generated in the combustion chamber 19 may be conducted to the fuel container accommodating portion U by the metal piece.
