Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to a piezoelectric ignition type or flint ignition type disposable gas lighter safety device.

(Prior art) Conventionally, widely used disposable gas lighters use a piezoelectric unit that generates high voltage electricity by striking a piezoelectric element with a striking mechanism, and a piezoelectric ignition type that generates a spark discharge to ignite. There are flint ignition types that use a file wheel to scrape a piece of flint or a flint and ignite it with the spark that ignites the lighter.In both cases, the gas jet nozzle connected to the gas tank inside the lighter body is moved in the drawing direction. The valve opens and gas is ejected from the nozzle. Then, in order to move the nozzle in the drawing direction, a valve operating lever is used, the tip of which is pivoted to the lighter body so that it can swing freely in the nozzle operating direction. is linked to the operation of the piezoelectric unit, and in the case of a flint ignition type, the finger operating the file wheel operates almost simultaneously.

(Problem that the invention aims to solve) Since this type of conventional gas lighter is ignited using a one-touch method, there is a risk of accidents such as fires and burns caused by children accidentally igniting the ignition. This may be the cause.

In view of the current situation, the present invention aims to provide a safety device for the above-mentioned disposable gas lighter, which prevents the opening of the valve with a simple structure and can prevent unexpected accidents in advance. .

(Means for Solving the Problems) The gist of the present invention in order to solve these conventional problems and achieve the intended purpose is to move the gas jet nozzle protruding from the lighter body in the drawing direction. A gas lighter, which has a valve that is opened by actuation, and has a valve operating lever pivotably supported in the direction of entry and exit of the nozzle with respect to the lighter body, one end of which is engaged with the nozzle. , a stopper is provided at a position on the valve opening operation direction side of the valve operating lever and is supported by the lighter body and is slidable in a direction perpendicular to the swinging direction of the operating lever; The safety device for a gas lighter comprises a recess into which the valve operating lever is fitted when the valve operating lever is at the operating end.

(Function) The safe operation of this gas lighter is to move the stopper to one side so that its concave part does not align with the valve operating lever, and the stopper comes into contact with the valve opening side of the valve operating lever. , the operation of the lever is blocked. By moving the stopper to the other side, the concave portion is aligned with the valve operating lever, and when a force in the direction of opening the valve is applied to the lever, the lever is moved in the direction of fitting into the concave portion, and the valve is opened.

(Example) First, an example in which the present invention is implemented in a piezoelectric ignition type disposable lighter will be described with reference to FIGS. 1 to 3.

In the figure, reference numeral 1 denotes a lighter body, which consists of a gas tank 2, a cap 3 that closes the opening of the gas tank 2, and an intermediate case 4 supported on the cap 3. A piezoelectric unit 5 is inserted. Although not shown in the figure, the piezoelectric unit 5 has a built-in piezoelectric element and a striking mechanism for striking it, and a high potential difference is created between the terminals 6 and 7 by pushing in the upper end.

The piezoelectric unit 5 is housed in the lighter body with its upper end protruding from the upper end of the intermediate case 4, and the ignition operator 8 is placed over the upper end of the piezoelectric unit 5.

A discharge electrode 9 connected to the terminal 6 protrudes from the front of the upper end of the operator 8, and a projection 8 on the front surface of the upper end protrudes.
a is prevented from coming off by a windshield 10.

Further, a gas jetting nozzle 11 is protruded from the upper end of the lighter body 1 toward the flame port 10a of the windshield 10, and when the valve operating lever 12 is operated in the pull-out direction, the valve 13 is opened and gas is jetted out. I try to do that.

The valve operating lever is molded from a conductive material, and has support shafts 14, 14 protruding from both sides of its approximately central portion, and these support shafts 14, 14 are inserted into bearing holes formed on the side wall surface of the intermediate case 4. It is rotatably fitted and supported, and has a slit 16 at its tip 12a.
The neck portion 11a of the nozzle 11 is fitted and engaged therein.

However, in this gas lighter, when the ignition operator 8 is pushed down, the operating part of the piezoelectric unit 5 is pushed down, the terminal 7 comes into contact with the operating part 12b at the rear end of the valve operating lever 12, and the valve operating lever 12 is pushed down. After being rotated around the support shafts 14, 14 and operated in the direction of opening the valve 13, a high voltage is generated and a spark discharge is made between the nozzle 11 and the discharge electrode 9, causing ignition. There is.

A stopper 17 is provided above the tip 12a of the valve operation lever 12 to prevent the lever 12 from moving in the valve opening direction. This stopper 17
is formed by bending a metal rod, and has a concave portion 18 facing downward with the same width as the valve operating lever 12 in the center portion, and shaft portions 19, 1 at both ends.
9 are projected in parallel arrangement with each other. and,
Both shaft portions 19, 19 are connected to both side walls 4 of the intermediate case 4.
a, 4a and the windshield, and protrudes from both sides of the lighter body in an axial direction so as to be freely removable and removable. Furthermore, this stopper 14 is made to reciprocate in the width direction at the upper part of the valve operating lever 12 by pushing both shaft parts 19, 19, and when it is at the end of one side of the reciprocating movement, As shown in FIG.
When the shaft part 19 enters into the valve operating lever 12 and is in a state where it can be rotated, and on the other hand it is at the end of the reciprocating movement on the other side, the shaft part 19 touches the tip part 12a of the valve operating lever 12, as shown in FIG. 3B.
The lever 12 comes into contact with the upper surface of the lever 12, making it impossible to move the lever 12 in the valve lifting direction.

The above-mentioned embodiment shows an example in which it is applied to a piezoelectric ignition type gas lighter, but the present invention is a gas lighter in which a flint stone 21 is rubbed with a file wheel 20 to generate sparks, as shown in FIG. In,
The same stopper 14 as described above may be arranged above the tip of the valve operating lever 12.

(Effect of the invention) The gas lighter safety device of the invention is constructed as described above, and has a valve operating lever that is slidable in a direction perpendicular to the swinging direction of the lever to the valve opening operating position, and one operating end of the valve operating lever. The valve operating lever is provided with a stopper having a recess into which the valve operating lever can fit, and the valve operating lever is made inoperable on one side of the reciprocating position.
It is possible to prevent accidental ignition with a simple structure, preventing accidental ignition by children, etc., and improving safety.
