[Technical field to which the device belongs]

 The present invention relates to an improvement of a gas lighter in which a liquefied gas suction member is hung in a lighter tank, and more specifically, it uses a simple and easy means to increase the surface area of metal heat collection than a conventional gas lighter. The present invention relates to an inexpensive gas writer capable of enhancing the heat conduction required for vaporization and efficiently recovering the liquefied gas in the liquefied gas suction core.

[0002]

[Prior art]

 Generally, in a gas lighter called a disposable lighter, the vaporization chamber and the surroundings of the valve are molded with a synthetic resin material, so the supply of the heat of vaporization necessary for vaporizing the liquefied gas of the fuel is insufficient. In addition, there have been various proposals for plastic gas lighters that have been equipped with a means for supplying heat of vaporization to the surroundings of the vaporization chamber and valve in order to eliminate the instability of the flame caused by such drawbacks. Has been issued.

Conventionally, as such a gas lighter, for example, one disclosed in Japanese Patent Publication No. 57-32304 is well known as a conventional example. In this conventional gas lighter, as shown in FIG. 4, a valve 5 is attached to the upper part of a synthetic resin gas tank (not shown), and a liquefied gas suction core S is inserted from the lower part of the valve 5 into the gas tank. In a plastic gas lighter, the lower end of the bulb 5 extends around the upper circumference of the core S, and the upper end surface contacts the lower surface of the nail-shaped stator 5n under the bulb 5, A metal heat collecting cylinder 6 extending along the upper peripheral surface of the core S into the gas tank is provided, and the heat of the liquefied gas is transferred to the nail-shaped stator 5n by heat conduction, and the liquefied gas is vaporized in the vaporization chamber. It employs a mechanism that supplies the heat of vaporization necessary for cooling to the vaporization chamber.

[0004]

[Problems to be solved by the device]

 However, in the gas lighter made of plastic disclosed in Japanese Patent Publication No. 57-32304, the heat collecting cylinder 6 does not extend to the inside of the gas tank, but the metal portion is still small, so that the heat of vaporization is reduced. However, the recovery rate (vaporization rate) of the liquefied gas sucked up in the liquefied gas suction core S was unexpectedly poor, and there was room for improvement.

[0007] Furthermore, the cause of insufficient supply of vaporization heat seen in such a plastic gas lighter is due to the insufficient supply of vaporization heat and also because the surroundings of the vaporization chamber and the valve are closed by an assembly member. That is to say, in other words, the supply path for the heat of vaporization other than the heat collecting cylinder 6 is not secured, so the supply of the heat of vaporization necessary for the vaporization of the liquefied gas is insufficient.

The present invention has been made in view of the above problems, and by a simple means, the surface area of metal heat collection is increased to increase the heat conduction necessary for vaporization as compared with a conventional gas lighter. Another object of the present invention is to provide an inexpensive gas lighter that can more efficiently collect the liquefied gas in the wick of the liquefied gas.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned conventional problems and achieve the intended purpose, the structure which is the gist of the present invention is such that the nail-shaped stator disposed on the lower end side of the valve through the filter and the upper end surface are A gas lighter comprising a liquefied gas suction core arranged so as to come into contact with the lower surface of the nail-shaped stator and have a lower end surface hung in the gas tank, wherein the nail-shaped stator is at least on the lower end surface side. In addition, the present invention resides in a gas lighter comprising a heat absorption rod inserted into the liquefied gas suction core.

Further, the present invention also resides in a gas lighter having a concave hole on the top surface side of the liquefied gas suction core for allowing insertion of the endothermic rod, and further, the nail-like shape. It is preferable that a cutout groove communicating with at least the upper end surface side of the stator is provided on the upper end surface side.

In the gas lighter of the present invention having the above-mentioned structure, the nail-shaped stator is provided with a heat absorbing rod inserted into the liquefied gas suction core at least on the lower end surface side. As a result, the surface area of metal heat collection is increased compared to the conventional one, and the heat transfer to the valve necessary for vaporization can be enhanced.

Further, if a concave hole for allowing the insertion of the heat absorbing rod is provided on the top surface side of the liquefied gas absorbing core, the connection with the heat absorbing rod can be easily made and the liquefied gas absorbing core can be easily absorbed. The heat absorbing rod is intervened in the core, and the absorbing core is always held around the entire peripheral surface of the heat absorbing rod.

In other words, since the liquefied gas is constantly in contact with the entire peripheral surface of the endothermic rod due to the capillarity of the wick of the liquefied gas, the heat of the liquefied gas is constantly applied via the endothermic rod. It will be conducted to the solid particles, and the vaporization efficiency of the liquefied gas will be promoted accordingly.

Furthermore, since the nail-shaped stator has a notch groove that communicates with the upper end surface side, the liquefied gas sucked up by the liquefied gas suction core is the top surface of the heat absorbing rod or the stator. While being contacted with and being vaporized, the vaporized gas is efficiently supplied to the upper part from the notch groove.

Since the heat of the liquefied gas filling the gas tank reaches the vaporization chamber and the vicinity of the valve more effectively, and further, the liquefied gas in the gas tank can directly contact the nail-shaped stator, the vaporization of the liquefied gas The vaporization heat necessary for the above is sufficiently supplied.

Therefore, the heat of the liquefied gas sucked up by the liquefied gas suction core S is transferred to the heat collecting rod 5n ₂ in the recess S ₁ to supply the heat of vaporization required for the burner. Moreover, since the liquefied gas that has permeated the wicking core S for liquefied gas comes into full contact around the heat collecting rod 5n ₂ , a large amount of heat of vaporization is taken away when the liquefied gas vaporizes. Even so, since a large amount of heat of the liquefied gas from around the heat collecting rod 5n ₂ can be supplied as heat of vaporization, the flame can be stabilized.
