Abstract

PURPOSE:To simplify an igniting operation and improve a safety by a method wherein a main body is slidably moved in respect to a casing encasing the main body to perform an igniting operation. CONSTITUTION:In case of performing an igniting operation, a case 6 is held by hands, a finger latch part 7 in pushed upward (in a direction of arrow B) with a thumb, a main body 1 is moved upward in respect to the case 6, and therefore a hook part 6a of the case 6 is engaged with a lever 4 to push it and thereby a valve of the fuel nozzle 3 is released and at the same time an operating element 5b of an ignition piezoelectric unit 5 is pushed to move by the projection 6b of the case 6, while the valve of the fuel nozzle 3 is released and thereafter the igniting piezoelectric unit 5 is operated. Then, the fuel discharged through the fuel nozzle 3 is ignited by a spark generated at the extremity end 5a of the ignition piezoelectric unit 5. Thus, it is made possible to assure a safe igniting operation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas lighter, and particularly to a gas lighter that is easy to ignite and is highly safe.

Conventional gas lighters are generally ignited by operating an ignition lever located near the tinder, and the finger operating the ignition lever is close to the flame ignited at the tinder. In addition, since the ignition lever is small, it requires relatively strong force to operate, and when carrying it, the ignition lever may get caught and operate inadvertently, causing ignition or flame adjustment. There were drawbacks such as the moon moving.

In view of the above points, it is an object of the present invention to provide a gas lighter that is easy to ignite, is highly safe, and prevents accidental ignition and flame adjustment.

This purpose is a piezoelectric unit for fuel tank ignition.

A gas lighter consisting of a fuel nozzle and a flame adjustment mechanism, comprising a main body incorporating a fuel tank, an ignition piezoelectric unit, a fuel nozzle, and a flame adjustment mechanism, and a case slidably surrounding the main body. characterized in that by moving the main body relative to the case, the valve of the fuel nozzle is opened and the ignition piezoelectric unit is subsequently activated to cause ignition. Solved by gaslighter.

The present invention will be explained below with reference to an embodiment shown in the drawings.
In FIGS. 1 and 2, reference numeral 1 denotes a main body, and together with a lid member 2 attached to the upper part of the main body, a sealed fuel tank 1a is formed. Reference numeral 3 denotes a fuel nozzle attached to the lid member 2 so as to penetrate therethrough, and the size of the flame when ignited can be adjusted by rotating the flame adjustment lever 3a in the direction of arrow A. There is. Reference numeral 4 denotes a lever pivotally attached to the lid member 2 for opening the valve of the fuel nozzle 3, and 5 is a piezoelectric unit for ignition of a well-known structure fixedly disposed on the main body l, the tip 5a of which is connected to the fuel nozzle 3. It extends near the mouth part 3b of the nozzle 3. Reference numeral 6 denotes a case that surrounds the main body 1 so as to be able to slide upward from the position shown in FIGS. 1 and 2 (see FIG. 3), and has a case on its inner surface that engages with one arm of the lever 4. A hook portion 6a for ignition and a protrusion 6b for activating the piezoelectric unit 5 for ignition are provided. In addition, main body 1
A finger rest 7 is attached to the surface not surrounded by the case 6, and a metal plate is attached to the surface exposed to the outside of the main body 1 other than the finger rest 7 for protection, aesthetics, etc. A thin plate 8 such as the one shown in FIG.

Since the embodiment of the present invention is configured as described above, when igniting, when the case 6 is held in the hand and the finger hook 7 is pushed upward (in the direction of arrow B) with the thumb, the main body 1 is moved against the case 6. is moved upward, and the hook portion 6a of the case 6 engages and pushes the lever 4, thereby opening the valve of the fuel nozzle 3. At the same time, the protruding portion 6b of the case 6 causes the ignition to occur. After the actuator 5b of the piezoelectric unit 5 for ignition is pushed and the valve of the fuel nozzle 3 is opened, the piezoelectric unit 5 for ignition is operated, and thus the fuel discharged through the fuel nozzle 3 is transferred to the piezoelectric unit 5 for ignition. It is ignited by a spark generated at the tip 5a. In this case, a return spring (not shown) is interposed between the main body l and the case 6, and the case 6
When the distributing push-up force is released, the case 6 automatically returns to the position where it completely surrounds the main body 1. Therefore, the flame adjustment lever 3a is completely covered by the case 6 when not in use (see FIG. 4), and can only be adjusted through the gap between the main body l and the case 6 when in use (see FIGS. 3 and 5). ).

As described above, according to the present invention, it is composed of a main body equipped with necessary mechanisms and a case slidably surrounding the main body, and ignition is performed by moving the main body with respect to the case. Therefore, when igniting, keeping your fingers away from the crater increases safety, and since the ignition operation is done by holding the case in your hand and pushing up the main body with your fingers, it is sure to be strong against your fingertips. It is extremely effective, as it can be easily carried out without applying any force, and since there is no ignition lever, there is no possibility of accidental ignition when carrying the device.
