Description

[Detailed explanation of the invention] This invention generates an electrical spark to ignite the gas.
Regarding so-called electronic gas lighters.

Conventional electronic gas lighters of this type open the valve of the gas passage from the gas tank to the nozzle at the same time as the lid is opened, and then the ignition switch is controlled to ignite the gas being injected from the nozzle. there were.

In this case, there was a drawback that when the lid was opened, gas (d) remained wasted until it ignited.

On the other hand, there are some that do not have a special lid, but operate the ignition switch to pull up the gas nozzle, so that gas is injected from the gas tank to the nozzle, and the ignition operation is performed at the same time as the gas is injected. This requires the operation of the switch to mechanically pull up the nozzle and open the gas valve, making the operation relatively heavy and difficult.

The purpose of this invention is to provide an electronic gas lighter whose ignition switch is easy to operate and which does not emit gas wastefully.

According to this invention, the electromagnetic actuation means is operated by operating the ignition switch, and the nozzle is pulled up by this operation.
That is, the gas is injected and at the same time, the high pressure generating means is operated by operating the ignition switch, and the generated high voltage causes a spark discharge to occur at the position of the gas injected from the nozzle.

Next, an embodiment of the electronic gas lighter according to this invention will be described with reference to the drawings.

FIG. 1 is a longitudinal sectional view showing an example of an electronic gas lighter according to this invention, in which a gas tank 12 is housed in a case 11 along its longitudinal direction.

A battery 13 is arranged alongside the gas tank 12, and a partition wall 14 is provided between the gas tank 12 and the battery 13 in the case 1.
It is located within 1.

That is, the case 11 is a slightly elongated rectangular parallelepiped, and the inside thereof is divided by a partition wall 14 along the longitudinal direction of the rectangular parallelepiped, and the gas tank 12 is housed in one side, and the battery 13 is housed in the other side.

A nozzle pull-up pipe 15 extends from the gas tank 12 above the gas tank 12, and the tip of the pipe 15 is connected to the nozzle 1.
6.

When the nozzle 16 is pulled up from the pipe 15 which is close to the flame emitting hole 18 formed in the upper plate 11a of the case 11, the gas passes through the pipe 15 from the gas tank 12 and enters the nozzle 16.
The liquid is injected from the hole toward the hole 18.

A flame adjustment means 19 is provided inside the pipe 15 on the gas tank 12 side, and an adjustment lever 21 engages with this, and by operating and adjusting this lever 21 that protrudes from the side wall of the case 11, the size of the flame is adjusted. I can do that.

An ignition switch 22, which is a push button switch, is mounted at a suitable location on the case 11, for example, on the upper side wall.

By pushing the button of this push-button switch 22 into the case 11, contacts 23 and 24 mounted inside the case 11 come into contact with each other.

A capacitor 25 is housed above the battery 13 in a portion of the case 11 on the battery 13 side, and an electromagnetic magnet 26 as an electromagnetic actuating means is disposed above the capacitor 25.

A support piece 27 is attached to a fixed portion of the electromagnet 26, and a rotary piece 38 is rotatably attached to the support piece 27.

When the electromagnetic magnet 26 is energized, the electromagnetic magnet 26
, one end of the rotating piece 38 is magnetically attracted, and the rotating piece 38 rotates around the support piece 27 .

The other end of the rotating piece 38 is extended to the position of the pipe 15 and engaged with the pipe 15.

That is, a collar 29 is fixed to the pipe 15, and this collar 29 is fixed to the pipe 15.
The rotating piece 38 is hooked on the lower side of the pipe 9 and the pipe 15 is pulled up with respect to the tank 12, so that gas is injected from the nozzle 16.

On the other hand, a microswitch 31 is installed in the case 11 above the moving piece 38, and the switch 31 is mounted on the rotating piece 38.
When the operating element 32 is in contact with the rotating piece 38 and is attracted to the electromagnetic magnet 26, the operating element 32 protrudes from the case of the microswitch 31, and the microswitch 31 is operated.

The operation of this microswitch 31 generates high voltage in the high voltage coil 33 of the high voltage generating means.

The high voltage coil 33 is provided near the nozzle 16, and one end of the coil from which high pressure is obtained is fixed to the nozzle 16, and the other end is located near the gas injected from the nozzle 16 and the injection port of the nozzle.

When high pressure is generated in the coil 33, a spark is generated between the nozzle 16 and the secondary output end of the high pressure generating coil 33, and the spark ignites the gas coming out of the nozzle 16, causing a flame 1.
7 exits from the hole 18.

For example, as shown in FIG.
60 is connected to both ends.

Therefore, the contacts 23 and 24 come into contact, the electromagnet 26 is energized by the battery 13, and the pipe 15 is pulled up from the tank as described above, so that the gas from the tank 12 is injected to the outside through the nozzle 16.

The movable contact of the microswitch 31 is the charging capacitor 2
5, and the other end of the capacitor 25 is connected to the battery 13.
The mover of the switch 31 is connected to the coil 26 through its normally closed contact.

As described above, the switch 31 is switched to the primary coil side of the high voltage generating coil 33 by the operation of the electromagnet 26.

In other words, when the switch 22 is pressed, its contacts 23 and 24 are turned on, and the capacitor 25 is charged through the battery 13 and further through the normally closed side of the microswitch 31. After a slight timing delay, the electromagnetic magnet 26 is activated and the rotating piece is turned on. 3
8 is rotated, the pipe 15 is pulled up, and the gas 18 is injected from the nozzle 16.

By the rotation of the rotating piece 38, the movable contact of the microswitch 31 is switched to the normally open side, and the electric charge charged in the capacitor 25 is transferred to the high voltage generating coil 33 through the switched switch 31.
A high voltage is applied to the primary side and generated on the secondary side of the coil 33, which generates a spark discharge between the nozzle 16 and one end of the secondary side of the high voltage coil, and the gas being injected from the nozzle 16. is ignited.

As shown in FIG. 3, the normally open side of the microswitch 31 is directly connected to the battery 13, and when the switch 22 is controlled and the contacts 23 and 24 are turned on and the electromagnetic magnet 26 is operated, the switch 31 is switched. You can also do this.

Alternatively, as shown in FIG. 4, when the switch 22 is controlled and its contacts 23 and 24 come into contact and the electromagnet 26 operates, the high voltage generating circuit 41 operates and the high voltage generating coil 33 generates high voltage. You can also do it.

As mentioned above, with the electronic gas lighter of this invention, there is no need to open and close the lid to open the gas valve, and the gas valve opens at the same time as the ignition switch is controlled, so gas is not wasted. There is no.

Moreover, since the gas valve is opened via electromagnetic actuating means by simple switch control, the switch operation is easy.

Since the ignition switch 22 can be operated very lightly in this way, if there is a risk that the switch 22 may malfunction even if it comes into slight contact with another object, the following steps can be taken.

For example, as shown in FIG. 5, two contacts 42 and 43 exposed on the case 11 are provided in series with the switch 22 and close to each other. .43 is electrically conductive, forming a so-called touch switch, and a switch 22 is provided in series with this, and a series circuit of both these switches is connected between the base and emitter of the transistor 450, so that both of these switches are turned on. When this happens, the transistor 45 becomes conductive and the electromagnetic magnet 26 can be operated.

Therefore, the ignition operation will not occur unless both switches are turned on at the same time, so even if only the ignition switch 22 is operated incorrectly, the ignition will not ignite.If the ignition switch 22 is a push button type or slide type, the switch 22 Contacts 42 and 43 of the touch switch are simultaneously activated by the operating finger 44.
If the switch is brought into contact with the switch, for the operator, it is no different from operating a single switch.

As shown in FIG. 6, a touch switch may also be used as the ignition switch 22.

A so-called plunger solenoid may be used instead of the electromagnet 26.
