Description

[Detailed description of the invention] This invention relates to a gas lighter filled with liquefied gas.

An embodiment of this invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a fuel tank, which is made in the shape of a cylindrical container with an open top, and liquefied gas is sealed inside.

A plug body 2 made of a soft elastic material such as rubber is fitted into the upper end of the fuel tank 1 and fixed with an adhesive 3.

A recessed hole 4 is provided in the center of the plug body 2, and a fuel injection pipe 5 is erected therein by fitting the proximal end thereof and solidifying it with an adhesive 3.

This fuel injection pipe 5 has a crater 6 at its upper end, and a small hole 7 which is closed at the lower end and communicates with the inside, and as shown in FIG. Since it is in pressure contact with the inner wall surface of the recessed hole 4, the inflow of fuel gas is prevented, but when the fuel injection pipe 5 is tilted forward, a gap between the bottom peripheral surface and the inner surface of the recessed hole 4 as shown in FIG. As shown in FIG. 6, which is a partially enlarged view, a gap is created so that fuel gas enters the small hole 7 and is ejected from the crater 6.

Note that this fuel opening/closing mechanism may be a normal mechanical valve.

There is a cylindrical windshield 8 on the top surface of the fuel tank 1.
An ignition mechanism 9 is provided which can be engaged with and moved up and down.

This ignition mechanism 9 has a file wheel 10 at the upper end and a flint inside, and is constantly pushed upward using the elastic force of a spring 11 that pushes up the flint. As shown in FIG. 5, an inclined plate 12 attached to this
presses the fuel injection pipe 5 to tilt it forward.

Now, a hanging part 13 is provided on the lower surface of the plug body 2 in correspondence with the bottom of the recessed hole 4, and extends from one point of the base end of this hanging part 13 to a corner of the bottom of the recessed hole 4, and further, Pass through to the proximal end again and 1
A strip of core thread 14 is pierced through.

(See FIG. 2) Both ends of the core thread 14 are exposed on the bottom surface of the plug body 2, and are in a gas containing member 15 made of a porous material such as urethane foam filled in the bottom surface of the plug body 2.
When a gas lighter is tipped over, it is immersed in liquefied gas.

Furthermore, the lower end of the fuel tank f is located at the vertical hole 1 as shown in Fig. 4.
6 is opened, and a valve-cum-sealing protrusion 17 (see Fig. 3) made of a soft elastic material such as rubber is attached to the valve-like sealing protrusion 17 (see Fig. 3), and its two ends, □ saucer-shaped portions, are tightly attached to the inner surface of the bottom of the fuel tank 1. It is fitted.

This invention has the above structure, and as mentioned above, the concave hole 4
Since the core yarn 14 is provided across the bottom of the hole, the impregnated fuel of the core yarn 14 that appears in the recessed hole 4 is consumed in response to the -times ignition operation. By using a certain thickness in advance, that is, a certain standard,
All products can be made to have a constant fuel injection amount, but in this case, the lower surface of the plug body 2 is provided with a hanging part 13 at a position corresponding to the bottom of the recessed hole 4, so during manufacturing When attaching the core thread 14, by piercing it along the hanging part 13 with a sewing needle, the core thread will naturally appear at the bottom corner of the recessed hole 4.
There is an advantage that the core thread 14 can be easily attached by piercing it downward across the bottom of the hole.

In addition, a sealing protrusion 1 that also serves as a valve is provided in the vertical hole 16 at the lower end of the fuel tank 1.
7 is mounted in a strongly sealed state by receiving the gas internal pressure with a saucer-shaped portion at the upper end, and the circumferential surface of the protrusion 17 and the vertical hole 16
Gas filling can be easily performed by applying the tip of the pump to the annular gap with the inner peripheral surface.

Claims (1)

[Scope of utility model registration request] A plug body 2 made of a soft elastic material such as rubber is fitted onto the upper end of a cylindrical fuel tank 1, and a concave hole 4 provided in the center of the plug body is inserted into the plug body.
A fuel injection pipe 5 having a fuel opening/closing mechanism is inserted and erected at the lower end, and a hanging part 13 is provided on the lower surface of the stopper 2 so that its base end corresponds to the bottom of the recessed hole 4, and extends across the bottom of the hole. A core thread 14 of a predetermined thickness is pierced through the plug body 2 provided with the drooping portion 13 with both ends thereof exposed at the base end of the drooping portion 13, and a vertical hole 16 communicating with the inside is provided at the lower end of the fuel tank 1. A gas lighter in which a valve-cum-sealing protrusion 17 made of a soft elastic material such as rubber and having a bulging upper end shaped like a saucer is inserted and fixed from the inside.
