Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a gas lighter, and particularly to a discharge ignition type gas lighter made of a synthetic resin material.

[Prior art]

Conventionally, a high voltage generator that generates high voltage by impacting a piezoelectric element or a high voltage generator that generates high voltage by boosting the battery voltage of the power supply has been used to generate discharge sparks in the gas ejection area. Various configurations of gas lighters for igniting fuel gas have been devised, and it is desired that this type of gas lighter be made thinner.

However, this type of gas lighter has problems with electrical insulation, has a complicated structure, and has not been able to be made thinner.

〔the purpose〕

SUMMARY OF THE INVENTION An object of the present invention is to provide a gas lighter equipped with a discharge ignition device that can eliminate the problems of the prior art described above, can be made thinner, and can prevent rattling of the nozzle operating rod.

[Summary of the idea]

In order to achieve the above object, the present invention provides that the free end of the ground wire drawn out from the other pole of the high voltage generator electrically connected to the nozzle is always elastically connected to the lower surface of the nozzle operating rod. It is characterized in that it extends to a position where it abuts.

[Effect]

With the above configuration, the present invention utilizes a lead wire and a nozzle operating rod to electrically connect the high voltage generator and the discharge electrode portion, and furthermore, the lead wire and the nozzle operating rod are connected to each other. Because it is held and guided by the exterior case and storage frame, the electrical lead structure is simple and its insulation properties are good, and the ground wire is always in contact with the bottom surface of the nozzle operating rod to prevent it from rattling. The entire lighter can be made thinner than conventional devices.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

This embodiment will be described in connection with a gas lighter having a circular appearance by joining hemispherical shells. As shown in FIG. 2, on both sides of the main body made of insulating synthetic resin, that is, the storage frame 1, there are recesses 1a for joining the plate-shaped exterior case 2 made of synthetic resin.
The recessed portion 1a has a depth such that the outer case 2 does not protrude from the storage frame 1.

As shown in FIG. 1, the main part of the storage frame 1 is a fuel tank 3 for storing liquefied gas, with a storage space 4 for the high voltage generator formed on the right side and a storage space 4 for the high voltage generator on the left side. A nozzle installation cavity 6 is provided above for protruding a nozzle 5 that is connected to the fuel tank 3 and spouts out fuel gas, and a support described later is provided between this nozzle installation cavity 6 and the storage cavity 4. A portion 7 is formed, and an upper portion of the storage space 4 is opened, and an acupressure piece 8 is arranged to cover this opening.

In this embodiment, as shown in FIG. 1, the storage cavity 4 houses a known piezoelectric generator 9, which is a type of high voltage generator. This piezoelectric generator 9 includes an outer cylindrical body 9a containing a piezoelectric element (not shown);
It consists of an operating body 9b that is slidably and loosely fitted into the outer cylindrical body 9a and generates a high voltage to the piezoelectric element by pressing down.

A wire 11 whose outer periphery is covered with an insulating tube 11a is connected to the high voltage side terminal 10a of the piezoelectric generator 9.
One end of the lead wire 11 is electrically connected, and the other end of the lead wire 11 protrudes from the left side of the support portion 7 of the storage frame 1, so that the exposed portion 11b of the protruding lead wire 11 serves as one of the discharge poles.

A part of a nozzle operating rod 13 made of a conductive material, one end of which engages with the neck of the nozzle 5, comes into contact with a support portion 12 that protrudes near the fuel valve 3a of the fuel tank 3. It serves as a pivot point. In addition, a free end 14a of a ground wire 14 pulled out from the low voltage side terminal of the piezoelectric generator 9, that is, the ground side, elastically contacts the lower surface of the other end of the nozzle operating rod 13, and the nozzle is connected via the nozzle operating rod 13. Electrically connect with 5. Therefore, the lead wire 11 and the nozzle operating rod 13 are separated and insulated from each other by the central wall of the support portion 7 made of an insulating material.

Therefore, the high voltage side terminal 10 of the piezoelectric generator 9
a and the low voltage side terminal are electrically connected to the electrode portion 5a at the upper end of the nozzle 5 in the nozzle installation space 6 and the discharge pole portion 11b of the lead wire 11, respectively.

As described above, regarding the electrical lead structure from the piezoelectric generator 9 to the discharge generating part, the storage frame 1 and the exterior case 2 are made of an insulating material, and the lead wire 11 and the nozzle operating rod 13 involved in the electrical lead are are held and supported in appropriate portions existing between the storage frame 1 and the exterior case 2, such as in grooves, so that the structure and members for insulation can be simplified.

Further, a metal or synthetic resin frame 15 is placed on the storage frame 1 above the nozzle 5, and the hanging portion hanging from the frame 15 is connected to the concave receiving groove (not shown) of the support portion 7. and attach the stop shaft 1 to the other hanging part.
6 is inserted, and the frame 15 is fixed to the storage frame 1. A flame port 17 is provided in the fuel gas ejection area of the nozzle 5 of the frame 15.

An acupressure piece 8 is supported on the right side of the storage frame 1, and this acupressure piece 8 is guided by a vertically elongated hole 18 and can move up and down, and the lower side is a piezoelectric generator 9.
It comes into elastic contact with the operating body 9b and is constantly pressed upward. During operation, the user presses down this acupressure piece 8 vertically. Then, an impact is applied to the piezoelectric element of the piezoelectric generator 9, a high voltage is generated in the piezoelectric element, and spark discharge is corrected between the exposed portion 11b of the lead wire 11 and the electrode portion 5a of the nozzle 5. Further, when the nozzle operating rod 13 acupressure piece 8 descends, it comes into contact with the lower protrusion 8a thereof, causing the nozzle 5 to rise and eject fuel gas.

Therefore, the fuel gas will be ignited by spark discharge.

When the acupressure piece 8 is not operated, it comes into elastic contact with the operating body 9b of the high voltage generator 12 and is pressed upward, as described above, and its position is regulated by the hanging portion of the frame 15. In Figure 1, code 19
shows the weld line of two hemispherical shells.

〔effect〕

As mentioned above, according to the present invention, the ground wire drawn out from the high voltage generator is extended to the bottom surface of the nozzle operating rod and is always in elastic contact with this, so that reliable grounding can be achieved. In addition, it is possible to provide a gas lighter that is effective in preventing rattling of the nozzle operating rod.
