Description

[Detailed description of the invention] (Industrial application field) This invention is based on a candle light that lights 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 distance 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. Fuel gas is emitted from a burner nozzle and ignited by a desired ignition means, such as a pine, to form a flame and ignite a candle, candle, or fireplace starter. The fuel gas is ignited using an ignition means separate from the igniter, and no igniter with an ignition means built into the igniter has been known.

However, the inventor had previously applied for a patent application in 1983-
No. 149024 discloses that a long igniter such as a conventional candle light is equipped with an electric ignition means to ignite fuel gas discharged from a burner nozzle without the need for a separate ignition means. In this invention, a gas release valve for allowing fuel gas to flow out from the fuel tank is disposed at the bottom of the fuel tank on the opposite side from the ignition part. The length of the gas pipe and operating pipe for flowing gas from the tank to the ignition part located above the igniter is almost the entire length of the igniter, and the gas pipe and operating pipe extend around the outer periphery of the fuel tank. Since the tank must be arranged so as to extend in parallel toward the ignition part, there is a problem in that the capacity of the tank becomes small.

In addition, the above-mentioned igniter had a complicated mechanism and was expensive, and it was also difficult to time the activation of the piezoelectric generator when the fuel gas was ignited.

(Problem to be solved by the invention) This invention solves the problem of inability to ignite due to increased electrical resistance by arranging an electric spark generator at the tip of a long igniter such as a candle light. In addition, the electric spark generator arranged at the tip part and the gas release valve arranged in the grip part are to be operated in a suitable relationship, and furthermore, the ignition is ensured, At the same time, the purpose is to ensure that the gas release valve can be opened and closed smoothly.

(Means for Solving the Problems) In order to solve the above problems, the means adopted by this invention is to attach an ignition part to the tip and a grip part to the base end of a rod-shaped intermediate part having a considerable length. A long and thin igniter, in which a fuel tank equipped with a gas release valve is disposed in the grip part on a surface close to the ignition part, and the fuel tank is connected to the gas release valve through a gas pipe inside the ignition part. A burner nozzle is arranged, the burner nozzle has a windshield member made of a wire wound in the shape of a coil spring on its outer part, and an electric spark generator is arranged in the ignition part adjacent to the burner nozzle. , electrically connecting the electric spark generator and the burner nozzle, and inserting an operating cylinder slidable in the longitudinal direction on the outer periphery of the ignition part;
The operating cylinder is operably connected to the opening/closing mechanism of the gas release valve and the operating section of the electric spark generator, and the opening/closing mechanism of the gas release valve is a valve opening/closing member that opens and closes the movable valve body of the gas release valve. a stopper member that operates in a direction perpendicular to the direction of movement of the movable valve body to hold the valve opening/closing member in the open position; and a stopper release button that can be operated from the outside. It is characterized in that it is biased to operate in the valve opening direction, and can be moved to a non-stopper position against the biasing force by a stopper release button.

(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. The 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.

Furthermore, an opening/closing member for the gas release valve, a valve opening/closing member for opening and closing the movable valve body of the gas release valve, and a stopper that operates in a direction perpendicular to the moving direction of the movable valve body to hold the valve opening/closing member in the open position. and a stopper release button that can be operated from the outside, and the stopper member is always biased so that the valve opening/closing member operates in the valve opening direction, and the stopper release button resists the biasing force to release the stopper from the non-stopper member. Since the burner nozzle can be moved to the desired position, it is possible to maintain and release the open position reliably and smoothly, and the burner nozzle has a windshield member made of a wire wound like a coil spring. Therefore, it is possible to achieve reliable ignition that is strong against wind, and it is also possible to use the windshield member as one electrode facing the burner nozzle.

2 is lowered by hand as shown in FIGS. 10 and 12, 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. 12, 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 burns out from the tip of the ignition part 2 while being protected by the windshield member 28, as shown in FIG. In addition, 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 as shown in FIGS. 6 and 7, its lower end is connected to a connecting member 31 located in the upper part of the grip part 1.
The gas pipe 16 rises through this working pipe 30,
It exits outwardly through an opening 32 in the upper part of the working tube 30 and reaches the burner nozzle 27 .

An L-shaped actuating piece 33 is fixed to the connecting member 31, and a protrusion 34 is formed on the actuating piece 33, and the protrusion 34 is in contact with the inner surface of the outer circumferential wall of the grip portion 1.

With reference to FIGS. 14 to 17, in conjunction with the movable valve body 12 extending outward from the upper part of the fuel tank 9,
A stopper member 37 for holding the valve opening/closing member 17 in the open position is disposed at the bottom of the lever-shaped valve opening/closing member 17 that opens and closes the valve opening/closing member 17 . The stopper member 37 is made of a plate-like member, as shown in FIG. Can be slid horizontally. and,
When the stopper member 37 slides below the valve opening/closing member 17, it prevents the valve opening/closing member 17 from descending, and the valve open position is maintained (see FIG. 15).

A step 39 is formed on one side of the stopper member 37, and when the side edge of the valve opening/closing member 17 comes into contact with the step 39, the stopper member 37 is prevented from sliding. Pins 40, 4 are provided on both sides of the stopper member 37.
One of the pins 40 is a guide pin that guides the horizontal sliding of the stopper member 37, and is inserted into and out of a guide tube 43 having a spring 42 therein. is constantly energized. Due to the biasing force of the spring 42, the stopper member 37 is always biased to slide in the direction of entering the lower part of the valve opening/closing member 17. An intermediate cylindrical body 44 is fitted into and fixed to the other pin 41, and the stopper release button 8 is positioned at the tip of the intermediate cylindrical body 44 so as to be able to freely come into contact therewith.

When the valve opening/closing member 17 rotates upward to raise the movable valve body 12, the valve opening/closing member 17 no longer contacts the stepped portion 39, so the stopper member 37 absorbs the elastic force of the spring 42. The movable valve element 12 slides into the lower part of the valve opening/closing member 17 and prevents the valve opening/closing member 17 from rotating back downwards, and the movable valve body 12 is held in the raised position and the valve open state is maintained to prevent the flow of fuel gas. Spillage is allowed. As the stopper member 37 slides, the intermediate cylinder 44 pushes the stopper release button 8 outward. Therefore, when extinguishing a fire, when the protruding stopper release button 8 is pushed in against the spring 45, the stopper member 37 slides through the intermediate cylinder 44 and comes out from below the valve opening/closing member 17. The valve opening/closing member 17 and the accompanying movable valve body 12 are allowed to descend, and the gas release valve 10 is closed. Then, one side edge of the lowered valve opening/closing member 17 is connected to the stepped portion 39 of the stopper member 37.
, the sliding movement of the stopper member 37 is stopped.

The guide cylinder 43 and the intermediate cylinder 44 are connected to the fuel tank 9.
The guide tube 43 extends outward through a hole 47 formed in a cylindrical wall 46 formed on the upper surface.
is fixedly positioned in contact with the inner surface of the gripping portion 1, as shown in FIG.

Next, the ignition operation will be explained. Referring to FIG. 19, 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 36.
The operating rod 24 of the electric spark generator 20 connected to
and the operating tube 30 is lowered. As the actuating pipe 30 descends, the connecting member 31 connected to its lower end descends, and the valve opening/closing member 17 is rotated via the actuating piece 33, causing the other end to rise due to the lever action, and the movable valve body rises. At the same time, the stopper member 37 enters the lower part of the valve opening/closing member 17. Thus, gas release valve 1
0 is opened to allow fuel gas to be discharged from the fuel tank 9, and this state is maintained. 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 ejection of fuel gas from the burner nozzle 27, the piezoelectric generator 20 is actuated by the operating rod 24 lowered by the first pin 25, and a high voltage is generated. Burner nozzle 27 and windshield member 28 via
A spark discharges between the two, and the ejected fuel gas ignites.

After ignition, the pressing force on the operating cylinder 22 is removed, and the operating cylinder 22 rises and returns to its original position. However, since the gas release valve 10 is held in the open position by the stopper member 37, the flame is continuously formed. 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 member 37 is slid and comes out from below the valve opening/closing member 17, so the valve opening/closing member 17 is lowered, the gas release valve 10 is closed, and the release of fuel gas is stopped. extinguish a 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.

(Effects of the invention) According to this 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, which is a good result. In addition, the electric spark generator disposed at the distal end and the gas release valve disposed within the grip on the proximal end can be operated in a timely manner in association with each other.

Furthermore, it is possible to reliably ignite and prevent blowing out by wind, and to maintain the open position of the gas release valve.
Extinguishing the fire by releasing the fire can be achieved smoothly and reliably.
