Description

[Detailed Description of the Invention] The present invention relates to an improvement of the fuel tank of a gas lighter.

Conventionally, the most common fuel tank for gas lighters is one in which a combustion valve and an injection valve are attached to a fuel tank formed by pressing or bending, and then fixed within a lighter case.

However, when the gas lighter becomes pale blue, the space inside the lighter case becomes narrower, and if a separately molded fuel tank is fixed inside the lighter case, the capacity of the fuel tank becomes smaller.

Therefore, in the case of a light blue gas lighter, it is proposed that the earthen wall and lower wall be welded to the inner wall of the lighter case by soldering, etc., and then a reinforcing plate is welded between the earthen wall and the lower wall to form a fuel tank. However, the work of welding multiple parts into the lighter case was complicated, and the strength was not sufficient.

In view of the above points, the present invention aims to provide a fuel tank for a gas lighter that is easy to process and has excellent strength.

Embodiments of the present invention will be described below based on the drawings.

A tank board 2, which will be described later, is soldered and fixed in a lighter case 1 with both upper and lower ends open, and a file wheel 3 and a fire extinguishing lid are rotatably supported on the upper part of the lighter case 1.

The tank board 2 is fixed within the lighter case 1 as described below.

That is, first, a metal plate 5 having the same width and thickness as the inner wall of the lighter case 1 as shown in FIG. 3 is punched out into an appropriate shape to form a tank substrate 2 having a hollow portion 2a and a vertically elongated flint storage portion 2b. (See Figure 4).

Next, a stepped portion 2d is formed on the partition wall 2c that bisects the hollow portion 2a to communicate the left and right hollow portions 2a, and is inserted into the lighter case 1 and fixed by soldering.

In this way, by fixing the tank board 2 inside the lighter case 1 by soldering, the hollow part 2a is fixed to the lighter case 1.
The fuel storage chamber 6 is surrounded by an inner wall.

Furthermore, a hole 2e communicating with the flint storage portion 2b, a hole 2f communicating with the left hollow portion 2a, and a blind hole 2g in the partition wall 2c are respectively drilled from above the tank substrate 2, while the tank From below the substrate 2, the flint storage section 2b
A hole 2h leading to the left side, a hole 21 leading to the left hollow part 2a, and a hole 2j leading to the lower step part are respectively bored.
Form a fuel tank as shown in the figure.

Then, a combustion valve 8 equipped with a nozzle 7 is screwed and fixed into the hole 2f, and an adjustment body 9 that compresses and relaxes the adjustment substance in the combustion valve 8 to adjust the amount of gas ejected is screwed into the hole 21. Hole 2j
The injection valve 10 is screwed and fixed thereto.

A guide rod 11 is loosely fitted into the blind hole 2g so as to be movable up and down, and one end of the upper end of the guide rod 11 is connected to the nozzle 7.
The opening/closing body 12 is urged upward by a spring 13 housed in the blind hole 2g, and comes into contact with a roller 14 supported on the lower end of the fire extinguishing lid 4. The opening/closing operation of the fire extinguishing lid 4 is facilitated.

Furthermore, a stone pushing body 16 with a stone pushing spring 15 attached thereto is screwed into the hole 2h, and a flint 1 housed in the hole 2e.
7 is pressed against the file wheel 3 by the stone pressing spring 15.

In this way, the flint 17 and the stone pressing spring 15 can also be stored using the tank board 2 and the inner wall of the lighter case 1, which eliminates the need for a storage cylinder for flints and the like that has been commonly used in the past. This is especially effective for cold-hearted gaslighters who don't have enough space in their lighter case to use their body.

Next, the operation of the above embodiment will be explained.

First, when the fire extinguishing lid 4 is opened, the extinguishing lid 4 automatically rotates with the help of the opening/closing body 12, and the opening/closing body 12 moves upward by the force of the spring 13, lifting the nozzle 7 and spouting fuel gas.

When the file wheel 3 is rotated in this state, the file wheel 3 and the flint 17 rub against each other to generate sparks, and the sparks ignite the fuel gas that has been ejected earlier.

The present invention is as described above, and in particular, by welding a tank board formed by punching a hollow part in the side of a metal plate to the inner wall of a lighter case, a fuel storage chamber is formed by the tank board and the lighter case. Therefore, the fuel tank is extremely simple to manufacture and has excellent strength, and it is possible to provide a fuel tank that is particularly effective in thin gas lighters in which the space between the inner walls of the lighter case is narrow.
