Description

[Detailed description of the invention] This invention ignites the fuel gas ejected from the nozzle by generating a discharge spark between the upper end of the nozzle that ejects the fuel gas and a discharge pole placed opposite thereto. Regarding the new structure of the discharge ignition type gas lighter, in more detail, the nozzle head is fixedly disposed opposite the discharge electrode, and the nozzle, which moves up and down to open and close the burner valve, is connected with a pipe. The present invention also relates to a discharge type gas lighter in which a ground circuit is constructed by connecting a nozzle head and a nozzle with a conductive wire, and will be described in detail below with reference to the drawings.

In the figure, reference numeral 1 denotes a box-shaped discharge unit casing made of an insulating material and having a storage space inside, in which a discharge spark generator circuit is housed.

Reference numeral 2 denotes a fuel tank fixedly disposed at the lower part of the discharge unit casing 1, and a burner nozzle 3 extends upward from one side of the upper surface in close proximity to one side of the discharge unit casing 1.

The tip of a lever member 4 is engaged with the base of the nozzle 3, and when the lever member 4 is actuated, the nozzle 3 is lifted and the burner valve is opened, allowing fuel gas to be ejected.

Reference numeral 5 denotes an electrode stand made of an insulating material disposed on the upper front side of the discharge unit casing 1 facing the nozzle 3,
It has an L-shaped cross section or a shape similar to this, and a discharge electrode 6 is attached substantially to the center of a vertical wall 5a adjacent to the front wall of the casing 1 and extends forward.

Further, the nozzle head 7 is fixed approximately at the center of the horizontal wall 5b.

The nozzle head 7 has a vertical hole penetrating vertically, and is provided with a large-diameter flange 8 on the outer periphery of the approximately central portion, and is inserted into the insertion hole 9 of the horizontal wall 5b from above and held there.

The nozzle head 7 extends further downward from the horizontal wall 5b of the electrode stand 5, and is elastically fitted into a circumferential groove formed on the outer peripheral surface of the nozzle head 7 in close proximity to the lower surface of the horizontal wall 5b. The nozzle head 7 is fixed to the electrode stand 5 by a ring-shaped fixing member 10 .

The best fixing member 10 is, for example, what is commonly known by engineers as an E-ring.

By using such a fixing member 10, the attachment or installation of the nozzle head 7 will be much easier than the conventional screw attachment, and will also help to reduce the space required.

The upper end of the nozzle head 7 ends opposite the discharge pole 6, and the lower end is connected to the upper end of the nozzle 3 by a connecting pipe 11.

The connecting pipe 11 is made of flexible rubber or plastic, and when the nozzle 3 rises, the pipe 11 is bent or the nozzle 3 slides inside the pipe 11, thereby inhibiting the upward movement of the nozzle 3. There is no risk of it happening.

A lead wire 12 electrically connects the nozzle 3 and the nozzle head 7 to form a ground circuit.

The use of such lead wires 12 allows the use of insulating but flexible pipes such as rubber, plastic, etc., which would most effectively accomplish the purpose of the connecting pipe 11.

The optimal lead wire 12 is, for example, a conductive elastic metal wire wound in a loose spiral.

This allows the nozzle 3 to move up and down without any hindrance, and the upper and lower ends are reliably pressed against the nozzle 3 and the nozzle head 7 due to its elasticity, so there is no need to employ special coupling means.

As mentioned above, the nozzle head 7 is fixedly attached to the electrode stand 5 and is separated from the nozzle 3, so the discharge gap between the upper end of the nozzle head 7 and the discharge electrode 6 is always constant. Furthermore, since all the lighters can be made uniform, concerns about discharge errors due to the size of the discharge gap are completely eliminated.

The nozzle 3 and the nozzle head 7 are electrically connected, and a lead wire 12 forming a ground circuit is formed by a loose spiral elastic metal wire wound around the nozzle 3. As a result, the shape of the ground circuit is extremely simple and requires only a small space, and its elasticity ensures reliable contact, and there is no risk of poor contact due to vertical movement of the nozzle. There is.

According to the present invention, there is no need to insert a coil into the connecting pipe 11, so the cheapest and easily available vinyl tube on the market is sufficient, and the lead wire 12 is provided loosely around the outer periphery of the connecting pipe. Since it is made of a loosely wound conductive coil material that is inserted, the state of connection between the burner nozzle 3 and the nozzle head 7 via the lead wire 12 can be visually confirmed from the outside, and the loosely wound state allows for loose insertion. Because of this, there is no risk that the elastic force of the lead wire will be reduced due to bending of the connecting pipe 11 or friction with its outer periphery, resulting in poor contact, and even though the conventional lead wire is inserted into the connecting pipe, As such, there is no risk that the elasticity of the lead wire will be diminished due to friction between the lead wire and the inner wall of the pipe or bending of the pipe, or that it will not be possible to confirm poor contact due to disconnection of the lead wire due to the inability to see from the outside. .
