Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement of an internal combustion gas lighter in which a mixed gas is ignited and burned in a lighter main body, and more specifically, to adjust the burner ignition power arbitrarily even with such an internal combustion gas lighter. The present invention relates to an internal combustion type gas lighter which can be easily and compactly mounted with an internal combustion mechanism such as a mixing pipe and a combustion cylinder without applying an unnecessary load on an ejection nozzle.
[0002]
[Prior art]
In general, in a gas lighter, a gas ejection nozzle is operated by a pressing operation of an ignition operation element to start gas ejection, and a spark is generated by operating an ignition means, so that gas ignition is performed. Such a gas lighter is roughly classified into a file type lighter (so-called flint type lighter) in which a igniter is rubbed with a file and ignited by a spark at that time, or a high voltage is generated by hitting a piezoelectric element with a hitting mechanism. There is a piezoelectric ignition type lighter (a so-called piezo lighter) that uses a piezoelectric unit and ignites by spark discharge. In addition, the top of the piezo lighter is covered with a lid so that it can be opened and closed, and the opening and closing operation of such a lid is performed. There is an internal combustion type gas lighter with a lid for operating the piezoelectric unit.
[0003]
Thus, among these gas lighters, particularly, in the case of recent piezoelectric ignition type gas lighters, a combustion cylinder or the like is built in the lighter main body, and ignition and combustion of gas mixed with air in the lighter main body are performed. Various kinds of wind-resistant (WIND-PROOF) gas lighters, which are so-called internal combustion gas lighters, have been proposed.
[0004]
Conventionally, as such an internal combustion type gas lighter, for example, the one disclosed in JP-A-63-91431 is well known as a conventional example. As shown in FIG. 14, this conventional lighter has a gas tank filled with fuel gas, and intake holes 6b ₁ , which suck air in by a negative pressure generated by ejecting the fuel gas from the gas tank at an increased flow rate. 6b 1 _... anda mixing tube 6b to promote mixing of the fuel gas and air, and a diffuser 6c which is provided continuously with said mixing tube 6b in order to decelerate the velocity of the mixed gas diffusion, the diffusion A combustion cylinder 6d connected to the diffuser 6c for further decelerating and diffusing the gas (mixed gas) mixed with the air by the device 6c so as to obtain a mixed gas with air having a flow velocity sufficient for ignition and combustion. And ignition means for igniting the combustible gas in the combustion cylinder 6d, so that ignition combustion is performed in the lighter main body.
[0005]
[Problems to be solved by the invention]
However, in the internal combustion type gas lighter disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 63-91431, the mixed gas produced by the jet jet is burned and ignited in a burner shape, so that it can be used without problems even in a strong wind. Although it has an advantage, it has a problem that it is not possible to arbitrarily adjust the heating power of the burner ignition because there is no gas amount adjusting screw, and the polymerization of the mixing pipe 6b, the diffuser 6c and the combustion cylinder 6d constituting the internal combustion mechanism 6 The assembling is troublesome, and since these are supported in a stacked state on the gas ejection nozzle 4c, the load on the gas ejection nozzle 4c increases, and the gas ejection nozzle 4c is pulled out (opened) by the valve operating lever. There was a problem that operation was difficult.
