Description

[Detailed Description of the Invention] This invention has a two-stage pressurizing stroke for stress to produce a piezoelectric effect, and the fuel valve is opened in connection with the first stroke, which is the power storage stroke, and in the second stroke. This invention relates to a gas lighter ignition device that can apply the required stress.

Conventionally, a lighter unit with a lid at the end houses a liquefied fuel tank with a fuel flux guiding device with a nozzle at the upper end, a piezoelectric generator with a pressure booster, an ignition mechanism, etc. Liquefied gas lighters are known.

In such liquefied gas lighters, a high pressure, for example 1 to αq kg, is required to produce the required piezoelectric effect. However, such gas lighters had the disadvantage that they required low pressurization for operation, leading to the shift to those powered by batteries or ICs for ignition.

The present invention has been developed in view of this point, and embodiments thereof will be described below with reference to the drawings.

In the drawing, 1 is an integrated lighter with an open top, and 2 is filled with a liquefied fuel such as CsH, a mixture of C5Hs and C4HIO. The tank 4 is a fuel injection control mechanism with a nozzle 3 at the top and a fuel supply valve, and a fuel flux guide pipe 5.
It is communicated with the tank 2 via. A piezoelectric element 6 is connected in series with a voltage step-up device such as a high voltage transformer, that is, an EC transformer, and the discharge electrode 8. 9 applies stress to the piezoelectric element 6 to produce a piezoelectric effect;
10 is a known force storage device that applies pressurizing force to the engine 9;
11 is a restraint pin fixed to the hammer 9; 12 is a restraint hole drilled in the end of the force storage device 10;
1 to prevent linear movement of the arm 9 in the axial direction, thereby allowing the power storage device 10 to store sufficient power.

Reference numeral 13t denotes a guide groove extending below and beside the restraint part 12. Reference numeral 14 denotes an operating rod 14 which is attached to the lighter unit 1 so as to be able to move linearly in the lateral direction thereof, and a rod 14 at one end thereof protrudes outside the lighter unit 1.

When the operation button 15 is pressed lightly with the tip of a finger, the other end moves the restraining pin 11 and uses the guide groove 15 as a guide to rapidly descend by the stored force stored in the force storage device 10 together with the lever 9, and The piezoelectric element 6 is pressurized to generate high stress.

Therefore, a piezoelectric effect is generated there, and the current is boosted by the high-voltage transformer 7, conducts to the discharge electrode 8, and causes the discharge electrode 8 to generate a spark discharge to open the fuel supply valve, which will be destroyed in the process described later. The fuel ejected strongly onto the nozzle 5 by the valve can be ignited and used as a lighter. Reference numeral 17 denotes a lid which is pivotally connected to the upper part of the lighter unit 1 so that it can be opened and closed by a shaft 18, and there is a base side surface 173 at the end of the lid, which is the lowest part when the lid is opened and upright. is provided, and when the lid rotates about the shaft 18, the base side surface 17a presses the top of the power storage device 10, and the suppression ends when the lid is opened and stands up. There is. 1
Reference numeral 9 denotes a lever rotatably attached to a lever shaft rod 20 mounted on the lighter unit 1; one end operates the fuel injection control mechanism 4 to open the fuel supply valve, and the other end operates the power storage device 10. Since the other end of the lever is placed on the unit bed 16 formed on the top of the unit, the other end of the lever also rotates as the base side surface 17a rotates as follows, that is, when the lid body 17 is opened as described above. Then, the base side surface 17a also rotates accordingly. Then, as the position changes due to the rotation, one end of the lever 19 is lowered together with the unit ped 16, that is, the power storage device 1o, and the lever 19 is used to open the fuel supply valve and force it onto the nozzle 3. causing the release of fuel,
On the other hand, the force storage device stores a pressing force against the arm 9 for the required stress based on the cooperation between the restraint pin 11 and the restraint part 12, and then the stored force is applied to the knob of the operating rod 14.・It is released by the operation of the pump 9, and its pressurizing force creates the series of piezoelectric conduction paths, through which a flame can be formed by igniting the discharged fuel based on the spark discharge of the discharge electrode. .

Next, instead of the lid 17, a pressurizing device for the force storage device 10, such as a known lever device or a sliding pressurizing device, may be used.

As explained above, according to this device, the force required to apply pressure to the hammer to produce the piezoelectric effect is stored in the force storage device when the lid is opened, and fuel is supplied in conjunction with the stroke. The valve is opened and fuel is released to form the required flame on the nozzle, and with a light operation of the operating levers 1 and 4, pressure is applied to the handle, stress is generated, and piezoelectric conduction sparks are generated. The series of steps of discharge and ignition can be performed continuously. Therefore, it is possible to easily and accurately provide a gas lighter that can be ignited with a light presser foot, which is highly desired in gas lighters.

As explained above, according to the gas lighter ignition device of the present invention, a fuel injection controller 4114 is installed in the lighter unit 1, which has a nozzle 3 at the top and a fuel supply valve operated by the nozzle 19. Contains a tank 2, on which a piezoelectric generator and a pressurizing device 9 for stressing said piezoelectric generator
In a gas lighter, a guide groove 13 is formed in the force accumulator 10 and communicated with the guide groove 13. The pressurizing device 9 is connected to the restraining hole 12 that communicates with the
An operating rod 14 for locking and moving the restraint bottle 11 attached to the lighter unit 1 is attached to the lighter unit 1 so as to be slidable in the lateral direction, and an operation button protrudes from the lighter unit 1 at the tip thereof. 15 is attached so that the force storage device 10 and one end of the lever 19 are interlocked with each other, and the storage force of the pressurizing force against the stress of the piezoelectric pot is controlled by the opening of the lid or other lever device. The fuel is stored in a power storage device using a sliding pressurizing device and is released as fuel gas in conjunction with the stroke of the fuel supply valve. Then, the power storage device is released from the restraint bottle 11 which is locked in the restraint hole 12.
This is done by operating the operating lever 14 with the operating button 15 to release the button, so the operation is as light and easy as operating the push button on a battery-powered lighter ignition device. Therefore, in such an operation, the processes associated with the pressurizing device, stress generation, piezoelectric conduction, spark discharge, and ignition of the discharged gas occur continuously. Therefore, it is possible to easily and accurately provide a gas lighter that can ignite with a presser foot using a light feel, which is a strong demand for gas lighters.
