Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention provides a light-emitting device in which the grip portion and the ignition portion have a considerable length, like a candle light used to light candles on a table at a wedding reception. Concerning long igniters that are spaced apart.

(Prior Art) Conventionally, like a candle light used to light candles on a table at a wedding reception, the grip part and the ignition part are separated by a considerable length, and the total length is about 60 cm to 1 m, for example. Long lighting tools are known, and in addition to the candle lights mentioned above, they can be used to light candles and lamps in churches, temples, etc.
It is also used to light the starter flame in a fireplace.

Such a igniter usually has a fuel tank that stores fuel gas in a liquid phase in the grip, connects it to a burner nozzle placed at the tip with a gas pipe, and opens the burner valve provided in the tank. The fuel gas is discharged from the burner nozzle and ignited by a desired ignition means, such as a pine, to form a flame and ignite a candle, a candle, or a starter light for a fireplace, and the fuel gas is discharged from the burner nozzle. The fuel gas is ignited using an ignition means separate from the igniter, and no igniter with an ignition means built into the igniter is known.

For a hand lighter that is shorter than a candle light, as shown in Japanese Utility Model Application No. 148273/1983, a piezoelectric generator is placed inside the grip on the proximal end of the lighter, and a piezoelectric generator is placed on the tip end of the lighter. It has been proposed that the hand lighter is ignited by generating an electric spark near the burner nozzle, but this hand lighter structure is not applicable to long candle lights with a length of 60 cm to 1 m. I can't do that.

With a long structure like a candle light, the length of the lead wire that connects the piezoelectric generator placed inside the grip on the proximal end to the vicinity of the burner nozzle on the distal end becomes long, which increases electrical resistance. As the spark increases, it becomes impossible to obtain an electric spark with sufficient energy for ignition, resulting in failure to ignite. In order to avoid this, if an electric spark generator is placed at the tip of the candle light close to the burner nozzle, the problem is how to configure the mechanism for operating the electric spark generator and the gas release valve. It was hot.

(Problems to be Solved by the Invention) This invention solves the problem of ignition failure due to increased electrical resistance in a long igniter such as a candle light, by disposing an electric spark generator at the tip of the igniter. At the same time, it is intended that the electric spark generator disposed at the tip and the gas release valve disposed within the grip be operated in a suitable manner.

(Means for Solving the Problems) In order to solve the above problems, the means adopted by the present invention is to provide an ignition part at the tip of a rod-shaped intermediate part having a considerable length, and a grip part at the base end. A long and thin igniter is attached to each, in which a fuel tank equipped with a gas release valve is arranged in the grip part, and a burner nozzle connected to the gas release valve via a gas pipe is arranged in the ignition part, an operating cylinder that disposes an electric spark generator in the ignition section in close proximity to the burner nozzle, electrically connects the electric spark generator and the burner nozzle, and is slidable in the longitudinal direction around the outer periphery of the ignition section; and a means for operably connecting the operating cylinder to the opening/closing mechanism of the gas release valve and the actuating part of the electric spark generator, and for stopping the opening/closing mechanism of the gas release valve in the valve opening operating state. The apparatus is characterized by comprising means for canceling the stoppage.

(Function) Since the electric spark generator is placed close to the burner nozzle and within the tip of the intermediate part, the lead wire connecting the two can be short, reducing electrical resistance and making it possible to The operating cylinder, which is slidably inserted in the longitudinal direction on the outer periphery of the igniter, is operably connected to the opening/closing mechanism of the gas release valve and the operating part of the electric spark generator, so that the electric spark placed at the tip of the igniter The spark generator can be operated without any trouble, and the operation of the electric spark generator and the opening of the gas release valve can be operated in a well-timed manner. The mechanism for opening and closing the gas release valve is held in the open position after the valve is opened, and the fuel gas continues to be released, so that the ignited flame can be kept burning for a required period of time.

(Embodiments) Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the entire igniter according to the present invention, which is composed of a grip part 1, an ignition part 2, and an intermediate part 3 connecting the grip part 1 and the ignition part 2, and has a total length of about 60 cm to 1 m. .

The grip part 1 is made of a cylindrical body with a slightly larger diameter than the intermediate part 3, and the open bottom is closed with a cap 4. A flange-shaped ring 5 is provided at the connecting portion between the upper end of the grip portion 1 and the intermediate portion 3 for decoration. An elongated window hole 6 extending in the vertical direction is formed in the grip part 1, so that the amount of gas remaining in the fuel tank can be visually checked from the outside. Furthermore, the decorative brim ring 5

Further, a stopper release button 8 for opening and closing the discharge valve is disposed at a position diametrically opposed to the injection valve 7. Referring to FIGS. 4 and 5, a fuel tank 9 disposed in the grip part 1 has a transparent or semi-transparent body, and the remaining gas in the tank can be visually checked through the window hole 6. There is.

A gas release valve 10 is provided at the bottom of the fuel tank 9 to allow fuel gas to flow out of the tank. The gas release valve 10 includes a fixed cylindrical body 11 fixed to the bottom wall of the tank, and a movable valve body 12 that moves in the axial direction within the fixed cylindrical body 11.
It has a sealing member 15 at its inner end that can approach and separate from the valve seat 13 located deep inside the fixed cylindrical body 11 and can open and close the valve hole 14, and the outer end of the movable valve body A flexible gas pipe 16 such as a silicon tube is connected to the distal end of the gas pipe 16 extending outward, and a lever-like valve opening/closing member 17 is linked thereto. A spring 18 is stretched between this lever-shaped valve opening/closing member 17 and the cap 4.
In addition, the movable valve body 12 is always urged in the valve closing direction. An operating rod 19 is connected to the free end of the valve opening/closing member 17, and when the operating rod 19 descends, it pushes down the valve opening/closing member 17 and moves the movable valve body 12 in the valve opening direction, as shown in FIG. let As a result, the fuel gas is allowed to flow out of the tank and flows into the gas pipe 16. Gas pipe 16 and operating rod 1
9 extends parallel to the outer circumferential portion of the fuel tank 9 upwardly. Preferably, the gas pipe 16 extending upwardly around the outer periphery of the fuel tank 9 is replaced from the flexible gas pipe to a rigid metal pipe.

Referring to FIGS. 6 to 10, the ignition section 2 includes a substantially upper end portion 3a of the intermediate section 3 in which the electric spark generator 20 is installed, a tinder section 21 attached to the tip of the intermediate section 3, and an intermediate section 3a. The operating cylinder 22 is movable in the axial direction along the outer peripheral surface of the upper end portion 3a of the portion 3. In the illustrated embodiment, electric spark generator 20
consists of a piezoelectric generator that generates high voltage by striking a piezoelectric element, and the high voltage side is connected to a burner nozzle, which will be described later, by a lead wire 23, and the low voltage side is grounded to the body. A first pin 25 fixed to the operating barrel 22 is in horizontal contact with the tip of the operating rod 24 of the piezoelectric generator 20, and the operating barrel 22 is lowered by hand as shown in FIGS. 8 and 10. When the piezoelectric generator 20 is pressed, the operating rod 24 is pressed down via the first pin 25, and the piezoelectric generator 20 is activated to generate a high voltage.

The crater portion 21 includes a collar-shaped attachment member 26 attached to the open end of the tip portion 3a, a burner nozzle 27 attached and held to the attachment member 26, and a winding arrangement around the outer part of the burner nozzle 27. It includes a windshield member 28 in the form of a coil spring. The lower end of the burner nozzle 27 is connected to the gas discharge valve 10 and the tip of the gas pipe 16 that has passed through the grip part 1 and the intermediate part 3. A side lead wire 23 is connected. Then, as shown in FIG. 10, a discharge spark is generated between the tip of the burner nozzle 27 and the windshield member 28, and the fuel gas flowing through the gas pipe 16 and ejected from the tip of the burner nozzle 27 is ignited. The ignited flame is exposed to the windshield member 2 as shown in Figure 8.
It burns out from the tip of the ignition part 2 while being protected by 8.
Incidentally, 29 is an electrical insulator for electrically shielding the burner nozzle 27 from the surrounding conductive members 3a, 2b, etc., and ensuring that discharge sparks are directed from the tip of the burner nozzle 27 to the windshield member 28. .

The intermediate portion 3 is made of a pipe material having a required length, and as shown in FIG. It is connected to the operating cylinder 22, and its lower end is connected to a connecting member 31 located at the upper part of the grip part 1. The gas pipe 16 is connected to this operating pipe 3.
0 and rises through the opening 3 at the top of the actuating tube 30.
2 and reaches the burner nozzle 27.

An L-shaped actuation piece 33 is fixed to the connecting member 31, and an elastic actuation piece 34 made of a plate spring is positioned at a slight distance from the tip of the actuation piece 33.
The elastic actuating piece 34 is fixedly connected to the upper end of the actuating rod 19. A coil spring 35 is stretched between the actuating piece 33 and the elastic actuating piece 34, and constantly urges the two apart. A stopper projection 36 is formed on the elastic actuation piece 34, and can be inserted into a hole 37 formed in the grip portion 1 as shown in FIG. The stopper release button 8 is disposed in and out of the hole 37, and by pushing the button 8, the engaged stopper projection 36 is released.
can be pushed out of the hole to release the engagement.

Next, the ignition operation will be explained. Referring to FIG. 14, first, the operation cylinder 22 is operated to move toward the grip portion 1. As the operation cylinder 22 moves, the operation cylinder 22 is moved by the first pin 25 and the second pin 38.
The operating rod 24 of the electric spark generator 20 connected to
and the operating tube 30 is lowered. As the actuation tube 30 descends, the connecting member 31 connected to its lower end descends, causing the elastic actuation piece 34 to descend via the L-shaped actuation piece 33. The lowered elastic operating piece 34 is stopped at the lowered position by the stopper protrusion 36 engaging the hole 37. The lowering of the elastic actuating piece 34 lowers the actuating rod 19 and pushes down the lever-like valve opening/closing member 17, thereby opening the gas release valve 10 and allowing the release of fuel gas from the tank 9. The released fuel gas passes through the gas pipe 16 to the burner nozzle 27, from which it is jetted outward.

Then, in synchronization with the jetting of fuel gas from the burner nozzle 27, the piezoelectric generator 20 is actuated by the operating rod 24 that is lowered by the first pin 25, and a high voltage is generated.
Spark discharge occurs between the burner nozzle 27 and the windshield member 28 via the fuel gas 3, and the ejected fuel gas is ignited.

After ignition, the pressing force on the operating barrel 22 is removed, and the operating barrel 22 rises and returns to its original position, but the elastic actuating piece 34 engages the stopper protrusion 36 and the hole 3.
7, the gas release valve 10 is held in the open position and the flame continues to form. Thus, it is possible to light multiple candles or candles with a continuous flame for the required time.

To extinguish the fire, press the stopper release button 8. When the stopper release button 8 is pressed, the stopper protrusion 36 comes out of the hole 37, so the elastic actuating piece 34 rises under the tension of the spring 18, and the lever-like valve opening/closing member 17 returns to its original position, causing the gas release valve 10 to move upward. The valve is closed, stopping the release of fuel gas and extinguishing the fire.

In the illustrated embodiment, the electric spark generator 20 is a piezoelectric generator, but it is not limited to this, and may be a battery discharge type electric spark generator that uses a dry battery as a power source to generate spark discharge, or other electric spark generators. It will be readily understood by those skilled in the art that spark generators may be utilized. The electric spark generator and the gas discharge need not be operated by a single operating means, but may be operated by separate operating means.

(Effects of the Invention) According to the present invention, even a long igniter such as a candle light can be used to generate electric sparks without losing the electric energy from the electric spark generator, and is suitable for use. This igniter is extremely superior as a igniter of its kind, as it is capable of igniting the igniter in a timely manner, and the electric spark generator placed at the tip and the gas release valve placed in the grip on the proximal end can be activated in a well-timed manner. can be provided.
