Description

  TECHNICAL FIELD The present invention relates to a gas lighter, and more specifically, a gas lighter that can cope well with ignition of a cigar with a large diameter by deforming a flame coming out from a flame hole of a lighter body into a wide and flat shape. It is about.

  As a conventional gas lighter, for example, one having the following configuration is known. This gas lighter includes a gas tank filled with fuel gas, a mixing tube that mixes fuel gas ejected from the gas tank with air, a diffuser that decelerates and diffuses the flow rate of the mixed gas mixed in the mixing tube, and a diffuser. A combustion cylinder that further decelerates and diffuses the diffused mixed gas to form a mixed gas of ignition and air having a flow velocity sufficient for combustion, and an ignition means that ignites the mixed gas in the combustion cylinder (see Patent Document 1). ).

  The gas lighter having such a configuration has an advantage that it can be used even under a strong wind because the mixed gas ejected by the jet jet is ignited and burned in a burner shape in the combustion cylinder.

JP-A-63-91431

  In this conventional gas lighter, the mixed gas ejected by the jet jet burns in the form of a burner, so the flame becomes stronger. For example, when igniting a cigarette, not only the tip but also one side is over-burned. It has the problem that it ends up.

  In addition, when igniting a cigar having a large diameter, a flame having a shape that evenly wraps the tip of the cigar is desired.

  Therefore, the gas lighter in the conventional example has a problem to be solved by providing a gas lighter that burns evenly cigarettes and cigars even if it is an internal combustion gas lighter.

The gist of the present invention for solving the problems of the conventional example is that a mixing pipe for mixing fuel gas ejected from a gas tank with air, a diffuser connected to the upper part of the mixing pipe, and surrounding the diffuser A gas lighter comprising at least a combustion cylinder that stably burns the fuel gas and a windshield member disposed above the combustion cylinder, wherein the combustion cylinder has at least an upper opening. The windshield member has a top portion, a front portion, both side portions, and a back portion, and a horizontally long groove portion is formed at a central position of the top portion, and a horizontally long groove portion is formed at the center portion of the groove portion. That is, a narrow slit-shaped flame hole is formed.

The combustion cylinder is formed in a flat shape as a whole;
Is included.

According to the gas lighter according to the present invention, the combination of the fact that the opening of the combustion cylinder is formed in an elliptical shape and the flame hole of the windshield member is formed in a horizontally long slit shape, Even a lighter with a strong flame, such as an internal combustion gas lighter, can make the flame coming out of the flame hole appear wide and flat. Accordingly, since the cigarettes and cigar tips are burned while being wrapped evenly, they can be ignited satisfactorily.
Furthermore, since the flame holes are horizontally long slits, the flame holes are formed narrower than conventional circular flame holes, and are therefore less susceptible to wind from above, and the fire is extinguished. There are various excellent effects that it is difficult.

  In addition, since the entire combustion cylinder is formed in a flat shape, not only the opening of the combustion cylinder is formed in an elliptical shape, but also various excellent effects that the lighter body can be formed in a thin shape. Play.

As shown in FIG. 5, the cap portion 16 can be opened and closed via a hinge portion 16 a on the back side of the main body case 12 , and the cap portion 16 covers the windshield member 13 when closed.

Further, as shown in FIGS. 1 and 11, a pair of long holes 17 are formed on the front side of the main body case 12 , and the ignition operation unit 18 can move up and down along the long holes 17. Is attached.

  The windshield member 13 is disposed above and in the vicinity of a combustion cylinder 19 to be described later. As shown in FIGS. 7 and 11, the top portion 13a, the front portion 13b, the side portions 13c and 13c, and the back portion 13d Have A horizontally long groove 13e is formed at the center of the top 13a, and a horizontally long and slit-like flame hole 20 is formed at the center of the groove 13e. An example of the dimensions of the flame hole 20 is desirably about 1 to 2 mm in width and about 7 to 9 mm in length.

  As shown in FIG. 1, the internal combustion mechanism 14 is provided so as to surround the mixing tube 21, the diffuser 22 connected to the upper portion of the mixing tube 21, and the diffuser 22, and stably burn the fuel gas. And a combustion cylinder 19.

  The mixing tube 21 is formed in a hollow cylindrical shape, and is a part that mixes fuel gas to be ejected from the gas tank 23 and air. The lower side of the mixing tube 21 communicates with the gas ejection nozzle 24 via the conductive tube 28.

  The diffuser 22 is a part that decelerates and diffuses the flow rate of the fuel gas while further promoting the mixing of the fuel gas flowing in from the mixing pipe 21 with the air.

  The combustion cylinder 19 is made of a ceramic material. As shown in FIGS. 8 to 10, the combustion cylinder 19 is formed in a flat shape as a whole, the upper opening 19a has an elliptical shape, and the lower part has a hole. 25 is formed. The hole 25 is a part that is inserted through the diffuser 22. Further, the combustion cylinder 19 is assembled with a discharge terminal 32 for igniting the fuel gas flowing in from the diffuser 22.

  As shown in FIG. 1, the piezoelectric unit 15 has an outer box 15 a and an inner box 15 b that can be fitted to each other in a stretchable manner. A piezoelectric element, a hammer, a return spring and the like (not shown) are incorporated in the inner box 15b, and the piezoelectric element is struck with a hammer to generate a high voltage.

  A conductive unit cap 15d is attached to the upper portion of the inner box 15b, and a lower end portion 15e of the unit cap 15d is in contact with one end portion of a valve operating lever 27 described later.

  In addition, the piezoelectric unit 15 has a conductive wire 29 connected to one electrode 15c extending upward, and its tip is connected to the discharge terminal 32 described above.

  An arm-shaped shaft 26 is assembled on the upper portion of the unit cap 15d. The shaft 26 is in contact with the locking portion 18 a of the ignition operation unit 18, and the shaft 26 moves up and down in conjunction with the vertical operation of the ignition operation unit 18. As a result, the inner box 15b is moved up and down via the unit cap 15d on the lower end side of the shaft 26.

  A valve operating lever 27 is disposed on the side of the outer box 15a. As described above, the lower end portion 15e of the unit cap 15d is in contact with the valve operation lever 27.

  In the gas lighter 11 configured as described above, when the ignition operation unit 18 is pushed down, the shaft 26 is pushed down in conjunction with it, and as a result, the unit cap 15d is pushed down. At the same time, the lower end 15e of the unit cap 15d pushes down the valve operating lever 27, and the gas ejection nozzle 24 opens. When the gas ejection nozzle 24 is thus opened, fuel gas is ejected from the gas tank 23 via the valve mechanism 30 and flows into the combustion cylinder 19.

  Almost simultaneously with the inflow of the fuel gas into the combustion cylinder 19, the shaft 26 pushes down the inner box 15b via the unit cap 15d, the piezoelectric element generates a high voltage, and a discharge spark is generated at the discharge terminal 32. By this discharge spark, the fuel gas flowing into the combustion cylinder 19 is ignited in a burner shape.

  At this time, the fact that the opening 19a of the combustion cylinder 19 is formed in an elliptical shape and the fact that the flame hole 20 of the windshield member 13 is formed in a horizontally long slit shape synergistically combines, and the flame. The flame 31 coming out of the hole 20 appears wide and flat (see FIGS. 11 and 12). As a result, it is possible to ignite the cigarettes and cigar tips evenly.

  Furthermore, since the flame hole 20 has a horizontally long slit shape (see FIG. 7), the flame hole 20 is formed narrower than a circular flame hole such as a conventional internal combustion gas lighter. It is hard to be affected by the wind of the sun and the fire is difficult to extinguish.

  Further, since the combustion cylinder 19 is formed in a flat shape, not only the opening 19a of the combustion cylinder 19 is formed in an elliptical shape but also an advantage that the lighter main body can be formed thinly (see FIGS. 2 and 4). ).
