Description

[Detailed description of the invention] (Field of industrial application) The present invention is a gas lighter that contains solidified fuel of liquefied petroleum gas and is equipped with a so-called aerosol valve mechanism and an ignition mechanism consisting of a file and a flint. Regarding improvements.

(Prior art) Conventional simple gas lighters, which store liquefied gas as a pressurized liquid in a fuel container, are generally equipped with a tubular or porous suction wick to handle the fuel, taking into consideration that the posture of use is not constant. Because it was necessary to supply the liquid phase part in the container to the lower part of the valve part, and to equip the lower part of the valve part with a liquefied petroleum gas vaporization device and a flow rate control member, the nozzle and valve mechanism had a large number of parts and had a complicated structure. It was not possible to use a valve mechanism.

In addition, in conventional gas lighters, it was necessary to provide a vaporizer and flow control member below the valve portion, and as a result, opening the valve mechanism required a structure in which a nozzle equipped with a rubber valve was pulled upward.The operating member that opened and closed the valve mechanism and the bearing members that supported the rotation of the operating member and the file were made up of separate members, and it was structurally impossible to integrate them, which increased the number of parts and the number of assembly steps.

(Problem to be solved by the invention) As mentioned above, conventional gas lighters require a suction wick and a vaporizer near the valve part, and as a result, the nozzle and valve mechanism have a complicated structure and a large number of parts, resulting in high manufacturing and assembly costs. This has led to an increase in the number of defective products.

Similarly, regarding the opening/closing operation of the valve mechanism, in conventional gas lighters, the opening/closing direction of the valve mechanism and the file rotation direction do not match, so it is necessary to provide a member for opening/closing operation separately from the bearing member that supports the rotation of the file. This resulted in an increase in the number of parts.

The present invention was developed in view of these issues, and its purpose is to simplify the structure by reducing the number of parts, manufacturing and assembly man-hours near the nozzle, valve mechanism and operating members. The aim is to provide a low-cost gas lighter.

(Means for solving the problem) In order to solve the above-mentioned problem, the present invention provides a fuel container 1.
A solidified fuel 2 of liquefied petroleum gas containing butane and propane as main components, a valve mechanism capable of releasing vaporized gas with a controlled flow rate, and a nozzle 7 provided on the upper part of the valve mechanism and the gas released from the nozzle 7. In a gas lighter equipped with an ignition mechanism capable of igniting vaporized gas, the operating member 6 with a pressing portion 6c that opens and closes the valve mechanism is attached to the file shaft 3a so that the file 3 of the ignition mechanism can rotate. file bearing 6
d is integrally provided, and the sliding portion 6a provided on the operating member 6 has a cylindrical shape and is inserted into the recess 1a of the fuel container 1,
The lighter is slidable in the vertical direction, and has a flint stone 4 inside, a rock pusher with one end in contact with the bottom of the recess 1a, and the other end in contact with the flint stone 4, and a spring 5 for pressing the operating member 6. The structure of the gas lighter is characterized by the following.

In addition, in the present invention, the file 3, the flint stone 4, the spring 5, and the pressing part 6 are movable in the vertical direction.
The operating member 6 equipped with c is the locking portion 1 of the windshield 13.
In some cases, the structure may be such that it can be locked to 3a.

(Function) The gas lighter of the present invention is a gas lighter comprising a valve mechanism and an ignition device capable of storing solidified fuel 2 in a fuel container 1 and releasing vaporized gas, in which the solidified fuel 2 contains butane or propane. The main components are liquefied petroleum gas and a solidifying agent, the valve mechanism is an aerosol valve mechanism, the ignition device is composed of a file 3, a flint stone 4 and a spring 5, and the fuel container 1
Inside is the solidified fuel 2 and the vaporized gas that has evaporated from the surface layer of the solidified fuel 2, and the spring 5 is contracted by the pressing force of rotating the file 3, and the nozzle 7 is pressed to open the valve. The mechanism opens and the vaporized gas is released from the tip of the nozzle 7, and at the same time the file 3 is rotated and the friction between the file 3 and the flint stone 4 ignites the vaporized gas, and the force of rotating the file 3 ignites the vaporized gas. Combustion continues while the operating member 6 is pressed, and by releasing the pressing force on the operating member 6, the valve mechanism is closed by the spring 11. The repulsive force of the spring 5, whose end is in contact with the flint stone 4, acts on the operating member 6 through the flint stone 4 and the file 3, pushing the operating member 6 up to the fitting part 6e to the fuel container 1 or the windshield 13.
The end portion of the operating member 6 is locked by the locking portion 13a to complete extinguishing the fire.

Note that since the inside of the fuel container 1 is composed of the solidified fuel 2 and the vaporized gas that has evaporated from the surface layer of the solidified fuel 2, no matter what the orientation of the lighter is, the fuel that enters the discharge path 1a is the solidified fuel 2
This is vaporized gas that evaporates from the surface layer of the lighter, and changes in the lighter's posture have no effect on the flame condition.

(Example) An embodiment of the gas lighter according to the present invention is shown in FIG. 1, which shows a vertical cross-sectional view, FIG. 2, which shows a cross-sectional view taken along line A-A' in FIG. 1, and FIG. 3
To explain based on the figure, a fuel container 1 made of thermoplastic resin etc. is filled with liquefied petroleum gas containing butane and propane as main components and a sodium salt of a fatty acid (for example, sodium stearate) as a solidifying agent.
A resin (for example, rosin, etc.) is enclosed as a solidification reinforcing agent, and the mixture is stirred and mixed to solidify.

On the other hand, a discharge passage 1b is provided in the upper part of the fuel container 1, and an aerosol valve and a nozzle 7 are provided.
A pressing part 6c that can press down the outer peripheral convex part of the file 3
A file bearing 6 that supports the rotation of the file shaft 3a
d. A through hole 6b that passes through the file 3 and can store the flint 4 and the spring 5 for pushing the stone in the vertical direction; a sliding surface between the outer surface of the through hole 6b and the inner surface of the recess 1a of the fuel container 1; 6a and a fitting part 6e with the upper end of the fuel container 1 are integrally molded. This configuration includes a windshield 13 for covering.

With the above configuration, the inside of the fuel container 1 is filled with solidified fuel 2.
The surface layer of the solidified fuel 2 is filled with evaporated gas of liquefied petroleum gas, and
The entire operating member 6 is pushed down by the pressing force trying to rotate the valve mechanism, and the vaporized gas is released from the nozzle tip. The ignition caused by the rotation of the file 3 forms a flame, which causes the file 3 to rotate. The operating member 6 is moved by the force of the movement.
Burn while pressing.

In this embodiment, the discharge path 6 is opened from inside the fuel container 1.
The vaporized gas released from the tip of the nozzle 7 through b.
A gas flow rate corresponding to a desired flame height is controlled by a flow rate control member 12 provided between the nozzle 7 and the valve member 9, and the solidified fuel 2 and the solidified fuel are contained in the fuel container 1. Since it is filled with vaporized gas that has evaporated from the surface layer of the lighter, no matter what position the lighter is in, the discharge path 1b is always supplied with only vaporized gas, forming a gas lighter that forms a stable flame. be.

(Effects of the invention) The gas lighter according to the invention eliminates the need for a vaporizer (suction wick, pressure reducing member, thermally conductive member, etc.) for vaporizing liquefied petroleum gas, and reduces the number of components related to the vaporizer. Now, it has become possible to use an aerosol valve mechanism with a simple structure instead of the conventional pull-up type valve mechanism, and the bearing part of the file can be used as the operating member of the aerosol valve by using the repulsive force of a stone pusher and a spring for pressing the operating member. Since the storage section for the flint and the spring, and the pressing section for the nozzle are constructed as one component, the number of parts can be reduced and the structure can be simplified compared to the conventional lever-type operating mechanism. In other words, a low-cost gas lighter can be mass-produced.

In addition, since the solidified fuel of liquefied petroleum gas is used, the valve part is always supplied with vaporized gas that evaporates from the surface layer of the solidified fuel, and the flame condition does not change depending on the attitude of the lighter, making it stable. This provides a gas lighter that produces a hot flame.
