[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquefied gas container heating device with a gas lantern used as an illumination source outdoors, and more particularly to a liquefied gas container heating device with a gas lantern in which a light emitting part can be slid and stored in a cylindrical casing.

[0002]

[Prior art]

 In recent years, barbecues in the garden at home and auto camping have become popular, and simple lighting outdoors without a power supply is required. Therefore, in the past, the bottom of a tubular casing configured to accommodate a liquefied gas cartridge inside was formed with a bottom lid so that it could be opened and closed, and a gas burner was placed in this tubular casing so that it could be raised and lowered. Of the gas cartridge inside the cylindrical casing in the use position, and the light emitting part can be switched to the storage position in which the liquefied gas cartridge is not stored. It is provided that the gas cartridge is attached to the bottom of the light emitting part.

On the other hand, as a gas lantern to be brought for camping or mountain climbing, there is also provided a gas lantern of a type in which a light emitting portion equipped with a burner is directly connected to the upper surface of a gas cartridge.

[0004]

[Problems to be solved by the device]

 However, in the case of combustion equipment that uses liquefied gas as a fuel source, the heat of vaporization is taken away when the liquefied gas is vaporized in the gas cartridge due to continued combustion, which lowers the temperature in the gas cartridge and slows the vaporization rate. Therefore, there is a problem that sufficient gas cannot be supplied.

For this reason, in the gas lantern of the type in which the light emitting portion is directly connected and fixed to the upper surface of the gas cartridge, the heat receiving portion arranged in the vicinity of the light emitting portion and the arc-shaped heat dissipation plate having a shape along the peripheral side surface of the gas cartridge are provided. A vaporization accelerating tool connected by a heat pipe is used to supplement the insufficient heat of vaporization.

However, in the case of the gas lantern in which the light emitting part can be slid and stored in the cylindrical casing without the fuel cartridge set, the relative distance between the light emitting part and the cartridge accommodating part depends on the use posture and the storage posture. Therefore, it is not possible to use the vaporization accelerator with the conventional structure, and it is impossible to prevent the decrease in the gas supply amount due to the decrease in the vaporization rate during continuous use for a long time. It was not possible to prevent the decrease in light intensity during continuous use. The present invention pays attention to such a point, and a gas lantern of a type in which a light emitting part is slid in a cylindrical casing when not in use can be obtained with a stable light amount even when continuously used for a long time. An object is to provide a heating device for a liquefied gas container.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention arranges an arc-shaped heat-dissipating plate in contact with the body of a gas cartridge inside a cylindrical casing in which a light-emitting part can be slid and housed. The heat pipe is projected upward from the plate, and a heat conducting rod with a heat receiving part is placed in the light emitting part near the gas burner in the light emitting part.The heat pipe and heat conducting rod penetrate the partition wall of the light emitting part. A through hole is formed, and a receiving part that receives the heat conducting rod from below is formed on the upper surface of the peripheral edge of this through hole, and the heat pipe and the heat conducting rod can be relatively moved below the partition wall of the light emitting part. It is characterized in that it is thermally connected with a connector made of a good conductor in the state.

[0008]

[Action]

 According to the present invention, an arc-shaped heat dissipation plate that comes into contact with the body of the gas cartridge is arranged inside a cylindrical casing that can accommodate the light emitting part by sliding, and the heat pipe is projected upward from this heat dissipation plate. A heat conducting rod having a heat receiving portion near the gas burner in the light emitting portion is arranged in the light emitting portion, and a heat pipe and a through hole through which the heat conducting rod penetrates are formed in the partition wall of the light emitting portion. A receiving part is formed on the upper surface of the peripheral edge to receive the heat conducting rod from below, and the heat pipe and the heat conducting rod can be moved relative to each other below the partition wall of the light emitting part with the good thermal conductor coupling tool. Since they are connected, the heat pipe and the heat conducting rod slide relative to each other according to the relative positional relationship between the tubular casing and the light emitting portion, and the overall height of the heating tool can be changed. As a result, the radiant heat from the burning burner can be reliably transmitted to the heat sink through the heat conducting rods and heat pipes during use to replenish the liquefied gas container with heat of vaporization, but when not in use. It can be housed in a tubular casing.

The inner surface of the lower end portion of the base portion (5), which is formed in a circular shape, can be inserted and engaged.

Although not shown in the drawing, a stay protrudes upward from the base portion (5) of the light emitting portion (3) while passing through the outside of the squirt (14), and a lid is attached to the upper end portion of the stay. The plate (13) can be engaged and fixed, and the hanging handle can be supported.
