JPH1122971A - Gas lighter provided with inlet opening which also works as burner port - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate the filling of gas by making use of a tiltable burner port, and to prevent the rotation of a tiltable valve stem at the time of filling gas. SOLUTION: A gas lighter is provided with an inlet opening which also works as a burner port. Namely, a tiltable valve stem is provided with a burner port 1 and the lower end of the tiltable valve stem is supported by U-shaped protrusions 8 of resilient members 6. A plurality of longitudinal groove portions 11 are formed on the lower end portion of the valve stem and corresponding to these longitudinal groove portions 11, longitudinal ridge portions 12 are formed on the central portions of the U-shaped protrusions 8. While fitting the longitudinal ridge portions 12 into the longitudinal graves 11, the valve stem is pressed downwardly and is lifted by a resilient force so as to stop the rotation of the valve stem.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas lighter having a crater and an inlet, and more particularly to a gas writer having an improved crater and an inlet so that gas can be easily injected from the crater using a tilting crater. Gas lighter having.

[0002]

2. Description of the Related Art Conventionally, injecting gas using a crater in a general gas lighter has been performed.
Based on the structure of the conventional disposable gas lighter,
No gas lighter could be used several times.

[0003]

SUMMARY OF THE INVENTION It is a first object of the present invention to easily inject gas using a tilting crater. A second object is to prevent the tilting valve stem from rotating during gas injection.

[0004]

According to the present invention, a tilting valve stem is provided with a crater and the tilting valve stem is provided with a crater.
0 is supported by the U-shaped projection 8 of the resilient member 6, and a plurality of longitudinal grooves 11 are provided at the lower end of the valve stem 10.
A vertically convex groove 1 corresponding to the center of the U-shaped projection 8
2, the valve stem 10 is pushed down and resiliently raised in a state in which the vertical convex groove portion 12 is fitted into the vertical concave groove portion 11, and the crater and the injection hole which can prevent the valve stem 10 from rotating. It is a gas lighter with an inlet.

[0005]

According to the present invention, there is provided a gas lighter capable of easily injecting gas using the tilting crater constructed as described above. Therefore, the fuel can be easily injected from the crater 1 by pressing down the tilting valve stem 10 to ignite, but gas can be easily injected using the crater. When the tilting valve stem 10 is pushed down during injection, the lateral hole 2 communicating with the crater 1 is released from being closed by the rubber tubular member 3 and the lateral hole 2 communicates with the inside of the gas tank 4 so that injection is possible. Become. At this time, the distal end of the tilting valve stem 10 is moved from the stationary state in which the corresponding concave groove and convex groove are supported by the distal end of the U-shaped projection 8 of the resilient member 6 in the U-shaped state. The figure-shaped projection 8 is pushed down while spreading it. The valve stem 10 is lowered until the lower surface of the flange-shaped projection 14 contacts the tip of the U-shaped projection 8. When the injection is completed, the tilting valve stem 10 is repelled upward by the U-shaped projection 8 of the resilient member 6 by removing the injection member, and returns to the original stationary state. Thus, the lateral hole 2 is closed again by the rubber tubular member 3. At the time of injection, the central longitudinal convex groove formed on the corresponding surface of the U-shaped projection 8 is formed in the concave groove portion 11 formed on four surfaces from the lower surface portion of the flange-shaped projection 14 of the tilting valve stem 10 to the tip of the valve stem 10. In the fitted state, the tiltable valve stem 10 is stable without rotating, and can be easily injected.

[0006]

FIG. 1 shows a stationary state of the present invention, and FIG. 2 shows a gas injection state. Equipped with the crater 1 on the tilting valve stem 10,
Near the lower end of the crater 1, the valve stem 10
Is provided, and a flange-like projection 14 is provided below the horizontal hole. From the lower surface of the flange-shaped protrusion to the tip of the valve stem 10, a groove 11 is formed on all four surfaces, and a central longitudinal groove 12 is formed on the corresponding surface of the U-shaped protrusion 8 so as to fit into the groove 11 over the four surfaces. The lower end of the valve stem 10 is supported by the U-shaped protrusion 8 with the grooves formed and fitted in the grooves. The rubber tubular member 3 is passed through its central opening so that the lateral hole 2 is always closed and can be opened at the time of injection.
And the rubber cylindrical member 3 fitted as such
Is made to contact and support the inner wall of the gas tank 4. The concave lower edge of the rubber cylindrical member 3 is adhered to the corresponding protruding upper edge 7 of the base 6 'of the corresponding synthetic resin U-shaped resilient member 6 with an adhesive. The lower end is supported by a resilient member supporting shoulder 15 formed on the inner wall of the gas tank 4. The U-shaped projection 8 extends downward from the base 6 ′, then inward, and upwards, so that it can support the lower end of the valve stem 10 as a resilient projection of the tiltable valve stem 10. I do. Inside the upper end of the gas tank 4,
Position the annular valve rubber fixing member 9 and fix the fixing member 9
Thus, the upper edge of the rubber tubular member 3 is pressed to prevent the rubber tubular member 3 from being detached. The inner diameter of the center opening of the annular valve rubber fixing member 9 is made slightly larger than the outer diameter of the valve stem 10 penetrating therethrough, so that the valve stem 10 can be slightly tilted. The lower end of the windshield member 5 is put on the outer periphery of the upper end portion of the gas tank 4, and the windshield member movement preventing protrusion 13 is provided on the outer periphery to prevent the movement of the windshield member. At the time of injection, as shown in FIG. 2, when the tilting valve stem 10 is pushed down, the lateral hole 2 communicating with the crater 1 is released from being closed by the rubber tubular member 3, and the lateral hole 2 is inserted into the gas tank 4. Communication and injection are possible. At this time, the distal end of the tilting valve stem 10 is moved from the stationary state in which the corresponding concave groove and convex groove are supported by the distal end of the U-shaped projection 8 of the resilient member 6 in the U-shaped state. The figure-shaped projection 8 is pushed down while spreading it. The valve stem 10 is lowered until the lower surface of the flange-shaped projection 14 contacts the tip of the U-shaped projection 8. When the injection is completed, the tilting valve stem 10 is repelled upward by the U-shaped projection 8 of the resilient member 6 by removing the injection member, and returns to the original stationary state shown in FIG. Thus, the lateral hole 2 is closed again by the rubber tubular member 3. At the time of injection, the central longitudinal convex groove formed on the corresponding surface of the U-shaped projection 8 is formed in the concave groove portion 11 formed on four surfaces from the lower surface portion of the flange-shaped projection 14 of the tilting valve stem 10 to the tip of the valve stem 10. Because it is in the mated state,
Since the tilting valve stem 10 is stable without rotating, it can be easily injected.

[0007]

According to the present invention, there is provided a gas lighter capable of easily injecting gas using the tilting crater constructed as described above. Therefore, although the fuel is spouted from the crater 1 by pushing down the tilting valve stem 10 to ignite, the gas can be easily injected using the crater. During injection, tilt valve stem 10
From the lower surface of the flange-shaped projection 14 of the valve stem 10.
The central longitudinal convex groove formed on the corresponding surface of the U-shaped projection 8 is in a fitted state with the concave groove portion 11 formed on all four surfaces up to the tip of the tilting valve stem 10, so that the tilting valve stem 10 does not rotate and stably There is an effect that can be easily injected.
