Description

Electric ignition apparatus of portable gas range

The present invention relates to an electric ignition apparatus for a portable gas stove, and in particular, to ignite the portable gas stove to be performed by continuous discharge, thereby giving accuracy of driving, and ignition is performed by an electric switch contact rather than a piezoelectric method. By preventing the damage of the parts to solve the user's time and economic disadvantages.

As shown in FIG. 1, the portable gas stove includes a burner 1 equipped with a gas ignition device, a detachable device 2 capable of attaching and detaching a gas can C, and a gas can C to be connected. A gas can mounting portion 4 having a gas inlet provided therein and having an adjustment mechanism 3 for controlling the discharge amount of the gas supplied to the burner 1 through the gas inlet, and a case 5 for fixing these parts. It includes, the burner (1) and the adjustment mechanism (3) are interconnected by a mixing tube.

Here, the configuration of the detachable device (2), the adjustment mechanism (3), the gas can mounting portion 4, etc. of the gas supply unit 6 for supplying it to the burner 1 side after the gas can (C) is mounted One side of the control mechanism (3) is provided with an ignition device for generating a flame in the burner (1) by igniting the crater of the burner (1) is supplied with gas by the control mechanism (3) is injected do.

2 is a perspective view showing a conventional ignition device configuration of the above-described portable gas stove.

Referring to the drawings, the conventional ignition device 10 is an ignition spark 11 generated in the ignition plug 11 is electrically connected to the ignition plug 11 and the ignition plug 11 mounted close to the burner of the burner (1) It is composed of a piezoelectric mechanism 12 for generating a, and the knob 13 is rotatably coupled to the control mechanism 3 to control the injection amount of the gas and to switch the piezoelectric mechanism 12 in a specific section.

The piezoelectric mechanism 12 is equipped with a switch 14 (collectively referred to as "piezoelectric switch") on one side so that the switching action by the knob 13 is performed, the switch 14 on one side of the knob 13 Pressing protrusion 15 is formed to pressurize the piezoelectric action.

In the ignition by the conventional ignition device configured as described above, the user rotates the knob 13 in a state where the gas can C is coupled to the adjustment mechanism 3 by the detachable device. Injecting into the fireball, in this state, the user further rotates the knob 13 so that the pressing protrusion 15 presses the switch 14.

Here, a high voltage is generated in the piezoelectric mechanism 12 by the pressurization of the switch 14, and the high voltage generated as described above is discharged through the spark plug 11, and sparks are ejected to the crater of the burner 1.

In the ignition apparatus of the conventional portable gas stove as described above, a piezoelectric mechanism is adopted as a means for generating an ignition spark, so that only one ignition spark is generated by one press of the switch. If not, the switch must be pressed several times, resulting in user dissatisfaction with incorrect driving.

In addition, the pressurization of the switch several times as described above causes a problem that the pressurization projections of the switch and the knob are broken, which is high enough to generate a driving sound in which the pressurization pressure of the switch is "clicked". This is a problem that occurs because the rotating force must be at least greater than the pressing force of the switch.

Therefore, when the switch and the pressing projections are damaged as described above, the user takes the time and economic disadvantages of repairing or replacing them, thereby lowering the reliability of the product.

The present invention was devised to solve the above-mentioned problems, and the electric switch configuration of the portable gas stove enables continuous discharge in the spark plug by one switch connection to provide high accuracy of driving. The purpose is to provide an ignition device.

Another object of the present invention is to provide an electric ignition apparatus for a portable gas stove that prevents breakage of components by allowing a switching action to be performed without providing a high pressing force when performing discharge for ignition.
