Description

[Detailed Description of the Invention] The present invention relates to a switch operating device for a battery lighter with a liquid crystal clock, in which a liquid crystal clock is incorporated into the battery lighter.

In other words, when incorporating a liquid crystal clock into a battery-powered lighter, in addition to the ignition switch for igniting the battery-powered lighter, a lighting switch is required to illuminate the liquid crystal display device. If the ignition switch and lighting switch are operated by separate controls, there is a risk that the number of parts will increase and the assembly work will be complicated. The drawback is that the switch is also turned on.

In view of the above points, this invention has a liquid crystal clock that allows you to turn on the ignition switch and lighting switch with a single operator, and that can operate only the illumination lamp when the lid is closed and only the ignition circuit when the lid is open. The purpose is to provide a switch operation device for battery lighters.

The operation will be explained below. By opening the lid 21, the cylinder 23 rotates clockwise and the gas opening/closing plate 27 moves upward.

As the gas opening/closing plate 27 moves, the gas ejection nozzle 24 also slides upward, and fuel gas is ejected from the gas ejection nozzle 24.

When the operator 29 is pushed into the case 1 in this state, the gas opening/closing plate 27 faces the operator 29 above the relief part 29a, so the operator 29 comes into contact with the gas opening/closing plate 27, and the ignition switch 8 is turned off. Injected.

However, the end 27a of the gas opening/closing plate 27 and the operator 29
The operator 29 cannot be pushed further into the case 1 because of the contact, and since the lighting contact member 31 is provided at the sliding end of the operator 29, the operator 29 and the lighting contact member 3 cannot be pushed further into the case 1.
No. 1 is not in contact with the lamp 1, so the illumination lamp 7a is not lit.

When the ignition switch 8 is turned on, the converter 9 is activated and the capacitor 10 stores charge. When the terminal voltage of the capacitor 10 becomes equal to or higher than the breakover voltage of the switching element 11, the charge stored in the capacitor 10 becomes It transiently flows through the switching element 11 to the primary side of the step-up transformer 12 and generates discharge sparks on the secondary side of the step-up transformer 12.

The capacitor 10 is repeatedly charged and discharged under the action of the switching element 11, and periodically generates continuous discharge sparks on the secondary side of the step-up transformer 12, and the fuel gas is ignited by the discharge sparks. .

Next, when the operator 29 is pushed into the case 1 while the lid body 21 is closed, the end 27a of the gas opening/closing plate 27 is located within the relief part 29a of the operator 29 and does not come into contact with the operator 29. Therefore, although the ignition circuit 2 does not operate, the operator 29 can move inward to the case 1 than when the lid 21 is open, and the operator 29 and the lighting contact member 31 can come into contact with each other, allowing operation. When the child 29 and the lighting contact member 31 come into contact, the lighting switch 38 is turned on.

When the lighting switch 38 is turned on, the lighting lamp 7
a lights up, the liquid crystal display device 7 is illuminated, and the day of the week and time can be confirmed even in the dark.

Next, the operation for adjusting the day of the week and time will be described. By pushing the first adjustment member 34 into the case 1 and turning on the set switch 19 for the first time, the watch circuit 5 is brought into a state where the day of the week is adjusted. At this time, when the second adjustment member 35 is pushed into the case 1 and the fast-forward switch 20 is turned on for the first time, the day of the week starts to be fast-forwarded and the day of the week can be adjusted to the correct display.

Next, by turning on the set switch 19 for the second time, the watch circuit 5 is set to a state for adjusting the time, and at this time, when the fast forward switch 20 is turned on for the second time, the time is fast forwarded. You can adjust the start time to the correct display.

Furthermore, by turning on the set switch 19 for the third time, the watch circuit 5 is set to a state for adjusting the minutes, and at this time, when the fast forward switch 20 is turned on for the third time, rapid forwarding of the minutes starts. It can be adjusted to display the correct minutes.

The present invention is as described above, and in particular, an ignition switch is provided with a gas opening/closing plate that operates a gas jet nozzle, and an operator that is provided on the side of the case so as to be slidable inward of the case, and has a relief part formed on the inner wall. The lighting contact member provided at the sliding end of the operating element and the operating element each constitute a lighting switch, and when the lid is opened, the gas opening/closing plate has its end connected to the sliding end of the operating element. When the operator moves, it comes into contact with the operator and comes off the escape part, thereby moving to a position that prevents the operator from sliding, forming an ignition switch circuit.Furthermore, when the lid is closed, the gas opening/closing plate is closed. The light switch circuit is constructed by allowing the end to escape into a relief part that does not come into contact with the operator even when the operator slides, and moving the gas opening/closing plate to a position that allows the operator to slide up to the end of the slide. By operating one operator, only the lighting lamp can be lit when the lid is closed, and only the ignition can be activated when the lid is opened. A battery lighter with a clock can be provided.
