Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pencil type gas lighter.

Several types of pencil-type gas lighters have been proposed, but the most difficult task for manufacturers is how to make the barrel of the gas lighter thinner and make it easier to use and carry around.

Currently, it is structurally impossible to make a pencil-type gas lighter with at least 8.6 bolts or less than about 9 bolts, no matter how small the parts are.

This had the disadvantage that the ignition device equipped with a nozzle and the ignition device containing a file or a piezoelectric element were installed in the same barrel, so the diameter of the shaft became thicker.

For this reason, a system has been proposed in which the ignition device is separated from the ignition device and connected in a hinge-like manner so that it can be turned upside down, but since it is frequently used, it can cause failures and is problematic in terms of structure and strength.

In view of the above-mentioned difficulties, the present invention was made with the aim of providing a gas lighter that is the slimmest and most stylish of all pencil-type gas lighters, is portable, and is superior in terms of structure and handling. be.

Embodiments of the present invention will be explained in detail below with reference to the drawings.

The pencil type of the present invention can be roughly divided into structural components: a cylinder body 1 of a gas cylinder with a gas inlet 6 provided at the lower part and a cylinder body of an ignition nozzle device communicating with the upper part, as shown in FIGS. 1 and 2. 2 are connected to form a pencil-shaped shaft body g, and a barrel cap 3 is removably attached to the barrel body g, and a lower part is inserted into the barrel cap, and a file 4 is attached to the upper part, and a file 4 is press-fitted to this. It consists of a cap body C which is an integral combination of a flint stone 4' (FIG. 4) and a supporting shaft tube 29 of a pyrotechnic file device provided with a clip rod 5.

When using the gas lighter, the cap body C is removed from the shaft body g, and the clip rod 5 is inserted and engaged with the shaft body g as shown in FIG.

The barrels 1 and 2 of the shaft body g, and the barrel cap 3 attached thereto, are all formed to have approximately the same diameter of 6 mm, and have a total length of approximately 1 mm.
It is configured in a pencil shape suitable for 26mm cell phones.

Next, the structures, connections, and coupling conditions of each of these outer cylinders will be sequentially explained.

First, in FIG. 3, reference numeral 7 denotes a wavy portion for sliding around the outer periphery of the barrel 2 of the ignition nozzle device, and 8 denotes a threaded groove for the barrel 2 provided on the inner periphery of the barrel 1.

Reference numeral 9 denotes a rubber ring, and reference numeral 10 denotes a rubber ring, and the cylinder cap 3 of the cap body C is removably attached to the attachment part, which is made by cutting the upper part of the cylinder body 2 to have a slightly narrower diameter.

The internal structure of the cylinder body 2 is such that a hollow part 12 is formed in the shape of a funnel at the bottom through a gas communication hole 11 that communicates with the gas cylinder of the cylinder body 1, and a seat plate 13 and an elastic body 14 are interposed in the core part. Then, the valve case 15 is screwed and fixed to a mark 16 carved on the inner periphery of the hollow part of the cylinder body 2.

A gas passage hole 17 is formed in the lower part of the valve case, and a nozzle 18 is movably inserted into the upper part of the hole by a spring 19 that exerts an upward force and a presser stop 20 fixed to the valve case.

The upper part of the valve case 15 and the nozzle 18 are connected to the attached part 10 of the cylinder body 2.
The zozzle crater 18b provided inside is slightly protruded from the upper edge of the adhered portion.

21 and 22 are 0 rings.

The nozzle 18 is located at the lower end of the gas ejection hole 23 passing through the switch 2
When the nozzle is moved downward, the opening/closing member comes into close contact with the upper protrusion 17a of the gas hole 17 to close the gas passage, and when the spring is moved upward, the passage of gas into the valve case is opened.

18a is an entry hole through which gas entering the valve case enters the nozzle.

25 is a guide groove provided vertically in the covering part 10 on the upper part of the cylinder;
is an insertion hole for the clip rod 5 of the cap body, which is bored in the cylinder body 2 and communicates with the guide groove.

Next, the structure of the cap body C is as follows:
As mentioned above, the supporting shaft cylinder 29 of the pyrotechnic file device includes a file 4 which is pivoted on a pin shaft 31 in a groove provided in the head. is attached, and a clip ring 32 is externally fitted and fixed immediately below it.

Reference numeral 33 denotes a mounting portion of the clip rod 5 that protrudes from one side of the clip ring 32, and the clip rod 5 is fixed downwardly to this mounting portion so as to be parallel to the support shaft cylinder.

5a is a retaining pin.

Reference numeral 34 denotes a receiver whose one end is screwed 34a into the lower end opening of the support cylinder, and a movable pusher 36 is inserted into the receiver.

A downward force is applied to the pusher by a spring 35 between it and the receiver and a spring 37 enclosed in the support cylinder.

The downward pressure of the spring against this pusher is greater than the spring 19 which exerts an upward force on the nozzle 18 housed in the valve case of the cylinder body 2.

The upper part of the barrel cap 3 is the clip ring 3 of the support barrel 29.
2 is screwed onto the lower marking 30 and covers the supporting shaft cylinder and the pusher 36 at its lower part to protect the firing file device, and the lower end is the attached part of the cylinder body 2 constituting the shaft body g. It is removably fitted onto the annular protrusion 27 provided at the base of the cap 10 to serve to connect the cap body C to the shaft body g.

28 is an annular groove provided on the inner periphery of the lower end of the barrel cap.

The structural action of the present invention is as described above, but in terms of how to use it, when it is used at all times, that is, when it is carried, the cylindrical cap 3 of the cap body C is attached to the attachment part of the shaft body g. When connected as shown in the figure, the gas lighter has a pencil-shaped appearance with a clip, so the clip rod 5 can be freely attached to clothing or the like and carried.

In this case, the shaft body g and the cap body C each have an annular protrusion 2
7 and the annular recessed groove 28, the fitting is semi-forcibly connected with a snap, and there is no risk of it coming off.

At the same time, the pusher 36 at the bottom of the shaft cylinder of the file ignition device mounted on the cap body C contacts and presses the nozzle 18 in an elastic manner so as to close the nozzle tip 18b as shown in FIG. Since the nozzle is moved, the switch 24 at the lower end of the nozzle contacts the upper protrusion 17a of the gas hole 17 to close the gas path.

The fitting connection of the cap body C is such that the downward elastic force of the springs 35 and 37 wound around the pusher is stronger than the upward force of the spring 19 exerted on the nozzle 13, so the floating action of the nozzle is completely prevented. There is no risk of gas leakage.

Next, when using the gas lighter, remove the cap body C from the shaft body g, and the nozzle 18 will be released from the pressing force of the pusher, while the nozzle 18 will move upward due to the upward force of the spring 19 inside the valve case. The switch 24 at the lower end opens the gas hole 17, causing the gas to rise into the valve case, enter the nozzle through the entry hole 18a, reach the nozzle 18b, and eject the gas.

The cap body C removed from the shaft body can be inserted into the insertion hole 26 of the cylinder body 2 along the guide groove 25 provided vertically in the attachment part 10 of the shaft body, and the clip ring 32 of the shaft body can be removed. The edge of the clip rod attachment part 33 is locked to the upper edge of the attached part 10, and the file 4 is positioned close to the upper side of the nozzle mouthpiece 18b, so that the gas ejected from the nozzle mouthpiece by rotation of the file can be easily removed. ignites.

After use, if the clip rod is removed from the insertion hole and the cap body C is attached again to the attachment part 10 of the shaft body, the nozzle moves downward to prevent gas from being ejected as described above, and the gas lighter can be clipped as a pencil type. It is portable.

As described above, the present invention is a pencil-type gas lighter with a new structure in which the ignition file device is connected to the upper part of the ignition nozzle device, and has the following features and advantages over the conventional pencil-type gas lighter.

In other words, it is possible to create a slender structure of about 6 mm compared to the conventional pencil shape, which could not be done below, with a total length of 125 mm when the cap body C is connected to the shaft body g when carried. By assembling and configuring the caliber and length to be suitable for a pencil type, we succeeded in creating a stylish and convenient pencil type gas lighter.

Next, in the present invention, the clip rod 5 fixed to the nozzle igniter support shaft tube 29 that is integrally combined with the tube cap 3 is not simply used as a decoration or a clip rod for clothing, but rather the clip rod 5 is attached to the tube body of the shaft body. It has a structural function that allows the shaft body to be inserted into the insertion hole 26 provided in the body to effectively connect the shaft body and the cap body attached thereto, which is a feature not found in other pencil types.

Then, by simply inserting the clip rod into the insertion hole, the edge of the clip rod mounting portion of the clip ring 32 is ignitably locked to the upper edge of the attached portion 10 of the shaft body surrounding the nozzle, as shown in FIG. At the same time, the cap body C is fixedly coupled to the shaft body g, and has sufficient strength and coupling action to support the ignition operation by rotating the file.

Further, since the insertion hole 26 communicates with the guide groove 25, it is possible to easily connect the shaft body and the cap body.

Compared to the conventional pencil type in which a file igniter is connected to the shaft in a hinge-like manner, this is a durable structure with fewer failures and is much more advanced and effective.

Furthermore, when the cap body C is attached, the springs 35 and 37 of the opening/closing element at the lower end of the nozzle and the nozzle 18b at the upper end forcefully close the gas passage to ensure the valve opening/closing function of the lighter, thereby creating a functional structure that prevents the risk of gas leakage. It is said that

As described above, the present invention can provide a pencil-type gas lighter that is excellent in portability, strength, functionality, and operability.
