Reference numeral 18 denotes a catalyst provided on a heat generating plate (hereinafter simply referred to as a heat generating plate) 17 on which a mosquito repellent agent is placed. Reference numeral 19 is a heater for heating the catalyst 18 to a temperature at which the catalyst can be reacted, and 20 is a battery serving as a power source of the heater 19. Reference numeral 21 is a switch for turning on / off the heater 19.

The operation of this embodiment will be described below. Body 11
When the fuel tank 12 is inserted into the fuel tank 12, the fuel gas flows through the joint portion 14 to the fuel gas jet nozzle 13. The fuel gas jetted from the fuel gas jet nozzle 13 entrains air and flows into the mixer 15, and a mixed gas of air and fuel gas is jetted from the mixed gas jet port 16 toward the catalyst 18. At this time, when the user presses the switch 21, the heater 19 is energized by the battery 20 to heat the catalyst 18. When the catalyst 18 reaches the temperature at which the catalyst can react, the mixed gas starts catalytic combustion. In this state, even if the switch 21 is released to stop the energization of the heater 19, the catalytic combustion is continued and the heat generating plate 17 reaches the evaporation temperature at which the mosquito-removing agent placed on the surface is volatilized.

As described above, according to this embodiment, since the fuel tank 12 is detachable from the main body 11, it is easy to inject the gas from the dedicated cylinder into the fuel tank, and the fuel gas is easily replenished.

Is a gas amount adjusting knob provided on the disposable gas lighter 12.

The operation of this embodiment will be described below. When the disposable gas lighter 12 is inserted into the main body 11, the operating piece 25 pushes down the gas opening / closing valve 26 of the disposable gas lighter 12 as the insertion proceeds. When the insertion is completed, the gas on-off valve 26 is pushed down and the gas starts to flow. If the gas amount adjusting knob 27 of the disposable gas lighter 12 is on the + side at the start of this inserting work, the position of the gas amount adjusting knob 27 is moved to the − side by the gas amount adjusting knob slide groove 24 as the insertion progresses. To do. That is, a small amount of gas always flows when the insertion is completed. After inserting the disposable gas lighter 12, slide the stopper 22 to slide the disposable gas lighter 12 into the main body 11
It is something to keep inside.

In this way, the fuel gas flows through the joint portion 14 to the fuel gas jet nozzle 13, entrains air, and is jetted from the mixer 15 from the mixed gas jet port 16 toward the catalyst 18. In this state, the user switches 2
When 1 is pressed, the battery 19 energizes the heater 19,
The catalyst 18 is heated. When the catalyst 18 reaches the temperature at which the catalyst can react, the mixed gas starts catalytic combustion. In this state, even if the switch 21 is released to stop energizing the heater 19,
The catalytic combustion is continued, and the heat generating plate 17 reaches the evaporation temperature at which the mosquito repellent chemicals are vaporized.

When the user slides the stopper 22 after use, the disposable gas lighter 12 is discharged to the outside of the main body 11 by the fuel tank discharge spring 23, and at the same time, the gas on-off valve 26 is closed and the supply of fuel gas is shut off. .

The operation of this embodiment will be described below. The catalyst heater 29 is inclined and attached to the main body 11 as described above, and a mixed gas of fuel gas and air is jetted from below the catalyst heater 29. Since the mixed gas ejection port 16 has a wide width, the mixed gas hits the catalyst 18 uniformly. Further, at this time, since the catalyst heater 29 is inclined, the mixed gas rises along the surface of the catalyst 18. That is, the mixed gas is uniformly supplied to the surface of the catalyst 18. Further, at this time, since the cross-sectional area of the mixed gas jet port 16 is small and the flow velocity of the jetted mixed gas is high, it is possible to entrain a larger amount of combustion air. Therefore, according to this embodiment, the catalytic combustion can be smoothly and surely executed.
