Description

Ball pen type gas lighter {a ball pen type gas lighter}

The present invention relates to a gas lighter (gas lighter), and more particularly to a gas lighter using a piezoelectric element made of a one-touch ball pen type (ball pen) is very easy to carry and use.

In general, a gas lighter is roughly classified into a fossil method in which sparks are ignited by igniting the fuel gas injected from a fuel tank, and a piezoelectric element type in which a spark is discharged between high voltage discharge electrodes.

In the fossil method, the fossil is closely adhered to the spark wheel, the spark wheel is rotated to splatter the flame, and at the same time, it is ignited by pressing the gas ejection lever located at the bottom of the wheel. It is used.

In the piezoelectric element method, when the ignition button is pressed, the nozzle of the fuel tank is opened to eject fuel gas and spark is generated at the discharge electrode of the piezoelectric element to ignite the gas mixed with air. Due to its advantages, it is mainly used for high-end lighters.

However, the gas ejection lever or the ignition button of the conventional gas lighters is configured to return to the initial position by the return spring when the external force applied during the ignition is removed. Therefore, the gas ejection lever or the ignition button must be kept pressed during the ignition time. So there was a problem that is very inconvenient to use. In addition, since the outer shape has a wide block shape of a size that can be gripped in the palm, it is not only convenient to carry, but also has a simple appearance because it can only be stored in a pocket or the like when carrying.

The present invention has been made in view of the above-described problems, and in the gas lighter using a piezoelectric element, the ignition button is formed in the form of a withdrawal button of a ballpoint pen, so that the ignition state is desired without continuously pressing the ignition button during the ignition time. It is an object of the present invention to provide a ballpoint pen-type gas lighter that can be maintained for a long time.

Another object of the present invention is to provide a ballpoint pen-type gas lighter which is portable and can be beautifully configured.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

In FIG. 1, the ballpoint pen-type gas lighter 1 according to the present invention includes a sleeve 10 having a crater 12 at the front end, a fuel tank 20 elastically biased toward the rear end in the sleeve 10, and a fuel tank. Positioned at the rear side of the piezoelectric element 30 to generate a spark, the push button 40 for operating the piezoelectric element 30 and the nozzle 22 of the fuel tank 20 in an open state. It consists of a locking means (50).

The sleeve 10 is formed of, for example, a synthetic resin having a conventional ballpoint pen size, and a conical metal cap 11 having a crater 12 in the center of the sleeve 10 is screwed so as to be decomposable. A plurality of vent holes 13 are appropriately arranged around the cap 11 so that oxygen can be easily supplied to the fuel gas to be ejected. The sleeve 10 may be formed in a cylindrical shape as shown, or may be configured in various forms, such as a triangle or a square, or a combination thereof.

The fuel tank 20 includes a body 21 filled with liquefied gas therein, and a nozzle 22 protruding from the front end of the body 21 to inject liquefied gas into an atomized state. The body 21 is movably inserted into the sleeve 10 and elastically biased to the rear end by the return spring 23. The nozzle 22 extends relatively long and is fixed to the sleeve 10 so that its tip can be located near the crater 12 of the cap 11. Accordingly, during ignition, the body 21 is moved relative to the nozzle 22 so that the nozzle valve (not shown) built in the body 21 is opened. That is, the nozzle valve of the fuel tank 20 of the present invention is composed of a push valve as opposed to a conventional gas lighter. On the other hand, the nozzle 22 is integrally provided with a gas amount adjusting lever 24 for appropriately adjusting the amount of fuel gas ejected from the body 21, and projects through the sleeve 10 to the outside.

The piezoelectric element 30 is connected to a main body 31 having high voltage discharge electrodes, an ignition button 32 assembled to the main body 31 to operate the discharge electrode, and ejected from the nozzle 22. It is composed of a spark tip 33 to splash the flame in the fuel gas. The main body 31 is fixed to the sleeve 10 and the ignition button 32 moves through the main body 31 in the axial direction to operate the discharge electrode. The ignition button 32 protrudes toward the rear end, and its front end is in contact with the rear end of the body 21 of the fuel tank 20. In addition, the spark tip 33 is fixed in the cap 11 of the sleeve 10 to be close to the nozzle 22, and is connected to the main body 31 through a connecting line 34.

The push button 40 operates the ignition button 32 while functioning as a cap closing the rear end of the sleeve 10. The front end of the pushbutton 40 is formed with a coupling hole 41 into which the rear end of the locking means 50 is fitted, and an assembly groove in which the rear end of the sleeve 10 is movably coupled around the coupling hole 41. 42 is formed concentrically. In addition, the outer periphery of the push button 40 is provided with a clip 43 for inserting the lighter 1 into a pocket of clothing or the like.

As shown in Figs. 2 to 4, the locking means 50 is a guide 51 fixed in the sleeve 10 and moved along the guide 51 to ignition button 32 of the piezoelectric element 30. It consists of a pusher (54) for pressing and the locker (57) for fixing the position of the ignition button (32) in a pressed state. The guide 51 has three guide grooves 52 at equal intervals on the inner circumference thereof, and has a locking jaw 53 at equal intervals on the front end surface between the guide grooves 52. In addition, the front end surface between each guide groove 52 and the locking step 53 is formed of inclined surfaces 51a and 51b which are inclined appropriately in either direction. This guide 51 is preferably formed integrally with the sleeve 10 as shown.

At the front end of the pusher 54, six teeth 55 are provided at equal intervals, and on the outer circumference of the front end portion thereof, a plurality of guide protrusions 56 are assembled to guide grooves 52 of the guide 51. The pusher 54 has a rear end coupled to the engaging hole 41 of the pushbutton 40 and moved together with the pushbutton 40. The locker 57 is movably assembled to the pusher 54, and six teeth 58 selectively engaged with the teeth 55 of the pusher 54 or the engaging jaw 53 of the guide 51 at the rear end thereof. It is provided. In addition, a plurality of rails 59 coupled to the guide grooves 52 of the guide 51 are formed at equal intervals on the outer circumference of the rocker 57.

The remaining symbol 57a is an assembly of the rocker 57 which is engaged with the pusher 54.

Next, the operation of the ball-point-type gas lighter 1 according to the present invention configured as described above will be described with reference to FIGS. 5A to 5D.

1 shows a state where the lighter 1 is extinguished. At this time, the body 21 of the fuel tank 20 is pushed back by the return spring 23, and as shown in FIG. 5A, the ignition button 32 of the piezoelectric element 30 is retracted. Thus, the locker 57 enters the inside of the guide 51 in a state of being engaged with the pusher 54. Therefore, the pusher 54 and the push button 40 are retracted as much as possible by the restoring elasticity of the return spring 23.

In this state, the pushbutton 40 is pushed forward as shown by the virtual line for ignition. Then, the rocker 57 is moved forward by the pusher 54 to exit the guide 51 and press the ignition button 32 of the piezoelectric element 30. Accordingly, the body 21 of the fuel tank 20 is moved forward while compressing the return spring 23, the nozzle valve is opened and the fuel gas is injected from the nozzle 22. At the same time, the discharge electrode of the piezoelectric element 30 is operated to splash the flame on the fuel gas ejected from the spark tip 33. The ejected fuel gas is then ignited and the flame protrudes out through the crater 12 of the cap 11.

Subsequently, when the force applied to the pushbutton 40 is removed, the body 21 of the fuel tank 20 is pushed backward by the restoring elasticity of the return spring 23, and at this time, the guide 51 is separated from the guide 51. As the locker 57 is caught by the catching jaw 53 of the guide 51 as shown in FIG. 5C, the return is limited, and the nozzle valve of the fuel tank 20 is held in the open position to maintain the ignition state continuously. It becomes possible. That is, when the rocker 57 exiting from the guide 51 is retracted by the restoring elasticity of the return spring 23, the rail 59 on its main surface elastically contacts the front end of the guide 51. Since the front end of the 51 is formed so that the plurality of inclined surfaces 51a and 51b face one direction, as shown in FIG. 5B, the rails 59 of the rocker 57 are inclined surface 51a of the guide 51. They retreat while being rotated along the rails, and thus, as shown in FIG. 5C, the rails 59 are restrained from the guide grooves 52 of the guides 51 and rest on the latching jaw 53.

Next, when the push button 40 is pressed again in the ignition state, the rail 59 of the rocker 57 is separated from the locking jaw 53 of the guide 51, and then the external force applied to the push button 40 is removed. The restoring elasticity of the return spring 23 causes the body 21 of the fuel tank 20 to retreat and to push the rocker 57 back by returning the ignition button 32 of the piezoelectric element 30. FIG. As shown in 5d, the rail 59 of the rocker 57 is rotated along the subsequent inclined surface 51b of the guide 51 and guided to the guide groove 52 as described above. Accordingly, the rocker 57 retreats to the initial position and enters the guide 51, and the pusher 54 and the push button 40 are returned to the initial position by the restoring force of the return spring 23. Then, the nozzle valve of the fuel tank 20 is closed to extinguish.

As described above, the ball-point gas lighter 1 of the present invention can maintain the ignition state for a desired time without continuously pressing the pushbutton 40.

Meanwhile, another embodiment of the present invention is shown in FIG. 6, which is a configuration in which the sleeve 10 ′ is formed in a triangle, for example, and the scale 14 is engraved at each corner in the above-described embodiment. Embodiment of such a configuration can also utilize the lighter 1 as a simple user to improve the usability of the lighter (1).

As described above, according to the present invention, ignition and extinguishing are performed by repeatedly pressing the pushbutton. Therefore, the ignition state can be maintained for a desired time without continuously pressing the ignition button during the ignition time. It becomes possible. In addition, since it is composed of a ball-point pen-type having a clip, it is easy to carry and can be configured in various forms.

Therefore, the present invention has an excellent effect of improving the ease of use, storage and aesthetics of the gas lighter.
