Description

[Detailed Description of the Invention] The present invention relates to a cigarette lighter that uses a high voltage generator incorporating a piezoelectric element as an ignition plug.

In conventional cigarette lighters, the means for guiding high voltage to the discharge gap is either an insulated high-voltage lead wire integrated with the high-voltage generator or a separate insulated high-voltage lead wire connected to the high-voltage generator. A method was used to interpose the discharge gap between the discharge gap and one of the discharge gaps. Such conventional means have many disadvantages in terms of ignition performance and product cost, such as retention of high-voltage lead wires, variations in discharge gap, and increased assembly man-hours.

The present invention has been devised to eliminate the above-mentioned drawbacks of the conventional art, and will be described below with reference to drawings showing one embodiment.

In the figure, reference numeral 1 denotes a high voltage generator incorporating a piezoelectric element, a hammer (not shown), etc., and is incorporated into a lighter case body 2 formed of an insulating material. Reference numeral 3 denotes a conductor for guiding a high voltage from one electrode 1a of the high voltage generator 1 to the discharge gap 4, and this conductor 3 is integrally formed with the lighter case main body 2. Reference numeral 5 denotes a gas jet nozzle communicating with a fuel tank (not shown) housed in the lighter case body 2, and the discharge gap 4 is formed by this nozzle 5 and the tip of the conductor 3. . 6 is a conductive operation button electrically connected to the conductive inner case 1b constituting the high voltage generator 1; 7 is a conductive operation button to which the nozzle 5 and operation button 6 are electrically connected and mechanically interlocked during operation; This is a gas lever for blowing out gas. Also, 8 is a hole 8a through which the flame passes.
This is a nozzle part cover with a

Now, if you press the operation button 6 in the direction of arrow A,
The operation button 6 contacts the gas lever 7 and is also electrically connected to the nozzle 5. Further, when the operation button 6 is pressed, gas is ejected from the nozzle 5 by the action of the gas lever 7. When the operation button 6 is further pressed, the piezoelectric element is impacted by a hammer through the inner case 1b, and the high voltage generator is A voltage higher than 1 is generated. This generated high voltage is applied to conductor 3
The gas is discharged in the discharge gap 4 formed between the nozzle 5 and the nozzle 5, and the ejected gas is ignited.

As described above, according to the cigarette lighter of the present invention, the two electrodes (nozzle and conductor) that make up the discharge gap are directly assembled into the same part (lighter case body), and the lighter case body also serves as an electrode stand. Therefore, by simply incorporating the high voltage generator into the lighter case body, high voltage can be reliably guided to the discharge gap, and the position and dimensions of the discharge gap can be stabilized, resulting in a stable structure for the lighter itself. It not only provides good ignition performance, but also reduces costs by significantly reducing assembly man-hours, and has extremely great practical value.
