Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in a piezoelectric gas lighter that ignites gas ejected from a gas nozzle by sparking the voltage generated by a high voltage generator that strokes up and down from a discharge nozzle. It is something.

BACKGROUND ART Conventionally, in this type of piezoelectric gas lighter, a discharge nozzle 11 is directly attached to the main body of a high voltage generator 10, as shown in FIG.
1 is slid along with the stroke movement of the high voltage generator 10, and when an impact occurs on the piezoelectric element of the high voltage generator 10, a spark discharge is generated from the discharge nozzle 11 that slides to the vicinity of the gas nozzle 12, thereby generating a gas nozzle. In addition, as shown in Fig. 3, the high voltage generator 20 is provided with a contact 21a, which comes into contact with the contact 21a and generates an electric current. A discharge nozzle 21b that is electrically conductive is fixedly supported near the gas nozzle 22 by an insulating electrode holding part 23, and when the contactor 21a comes into contact with the discharge nozzle 21b due to the stroke movement of the high voltage generator 20, a spark discharge is generated from the discharge nozzle 21b. There is also a device configured to ignite the jet gas of the gas nozzle 22 by performing
issue). In any of these gas lighters, the grounding fitting 13 or the grounding plate 24 is protruded from the high voltage generators 10, 20, and when it comes into contact with the valve levers 14, 25, the gas nozzles 12, 22 are pushed up, so that gas is ejected. ing.

Problems to be Solved by the Invention Among these, in the former case, the point at which an impact occurs on the piezoelectric element due to the stroke movement of the high voltage generator 10 is not necessarily constant, and the discharge nozzle 11
The gap between the gas nozzle 12 and the gas nozzle 12 tends to vary, and in the case of the latter, the contact 21a
Since a gap is forced to occur between the discharge nozzle 21b and the discharge nozzle 21b during discharge, a loss occurs in discharge energy, and good ignition performance cannot be obtained in either case. In particular, in the latter case, the contactor 21a must be attached to the high voltage generator 20 separately from the discharge nozzle 21b, which has the disadvantage of increasing costs due to the large number of parts and time-consuming assembly.

Means for Solving the Problems In the piezoelectric gas lighter according to the present invention,
A discharge nozzle that has spring properties and can be flexibly deformed is attached to a high voltage generator, and the tip of the nozzle is fixed protruding near the gas nozzle using an insulating holding frame, and the discharge nozzle is attached to a high voltage generator, and the tip of the nozzle is fixed protruding near the gas nozzle using an insulating holding frame. The discharge nozzle is configured to discharge from the tip of the discharge nozzle, which bends and deforms, to the gas nozzle.

Function In this piezoelectric gas lighter, since the tip of the discharge nozzle is fixed, the discharge gap between the gas nozzle and the gas nozzle can be kept constant, resulting in good ignition performance. Since it only needs to be installed between the voltage generator and the voltage generator, the installation does not take much time and the number of parts can be reduced.

Embodiment The following will be described below with reference to FIG.

This gas lighter uses a high voltage generator 1 incorporating a piezoelectric element, and is configured as a piezoelectric type that generates a spark discharge from a discharge nozzle 2 to ignite gas ejected from a gas nozzle 3. The discharge nozzle 2 is made of a material that is conductive and has spring properties so that it can be bent and deformed. This is 40
It can be formed using a soft metal plate such as a phosphor bronze plate having a thickness of about 60 μm, or it can be formed using a flexible plate with electrodes printed on a flexible film. One terminal side thereof is connected to a piezoelectric element built into the high voltage generator 1, and the other terminal side is mounted near the gas nozzle 3 so as to protrude with a predetermined discharge gap. The tip end thereof is fixedly supported through the thickness of an insulating holding frame portion 4, and is attached to the gas nozzle 3 so as to maintain a constant discharge gap. The gas nozzle 3 is supported by a valve lever 5 so as to be able to move up and down, and is assembled so that the gas flow path can be opened by pressing its free end side with a ground protrusion 6 protruding from the high voltage generator 1. There is.

In the piezoelectric gas lighter configured in this way,
When the operating head attached to the shaft head of the high voltage generator 1 is pressed, the high voltage generator 1 strokes downward against the compression spring housed inside. During this process, discharge nozzle 2
Since the entire axis is made of a metal material having spring properties, it bends and deforms following the stroke motion of the high voltage generator 1. Furthermore, when the high voltage generator 1 is stroked down to a predetermined position and the ground protrusion 6 comes into contact with the valve lever 5 to open the gas nozzle 3, the impact of the piezoelectric element built into the high voltage generator 1 causes sparks to be emitted from the discharge nozzle 2. is generated, and the gas ejected from the gas nozzle 3 is ignited. Even at this point, the discharge terminal side of the discharge nozzle 2 is fixed by the holding frame part 4, so that sparks can be discharged from a fixed position without affecting the discharge gap formed by the upward deflection of the gas nozzle 3. Become. After the ignition operation, the high voltage generator 1
When the pressing force is released and the compression spring housed inside strokes upward, the discharge nozzle 2 also flexes and returns to its original position, and the gas nozzle 3 blocks the gas flow path by the spring deflection of the valve lever 5. gas combustion can be stopped.

Effects of the Invention As described above, according to the piezoelectric gas lighter according to the present invention, the discharge gap between the gas nozzle and the gas nozzle can be kept constant. It is now possible to obtain reliable ignition using the electrical energy generated by the high voltage generator, and the discharge nozzle only needs to be stretched between the high voltage generator and the holding frame, making assembly simple and inexpensive to manufacture. .
