BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas lighter.

0002

[Prior Art and its Problems] Fig. 2 shows a conventional gas lighter.The inside of a plastic casing 1 is divided into upper and lower halves by a partition wall 2, and the lower part is a liquefied gas chamber. The upper part is considered to be an atmospheric chamber. Butane B is stored in the liquefaction chamber as a liquefied gas, and a tube 3 is immersed in this, and a filter 4 is attached to the upper end of the tube 3.
is installed. This filter 4 is attached to a partition wall 6, which defines a first gasification chamber 5, and the above-mentioned filter 4 faces this.
A conical hole 7 is formed in this opposing portion of the partition wall 2, and this surface serves as a valve seat in which a conical valve body 21 can be seated as shown. A shaft member 12 is attached to this valve body 21,
This has a shaft hole 12a in the axial direction, but a small hole 18 is formed near the valve body 21 at the lower end thereof, and communicates with the second gasification chamber 8 through this small hole 18. . The shaft member 12 is urged downward in FIG. 2 by the spring 9. That is, the upper end of the spring 9 is fixed to a spring receiving member 22 fixed to the inner wall of the casing 1, and the lower end thereof is received by a spring receiving flange 12b provided integrally with the shaft member 12. . That is, it is in a compressed state. Therefore, in the illustrated state, the valve body 21 is pressed toward the valve seat 20 to close the valve. That is, the first gasification chamber 5 and the second gasification chamber 8 are isolated from each other.

A flame nozzle 17 is provided at the upper end of the shaft member 12, from which a flame F is generated when the gas lighter is used, as shown in the figure.

[0004] Also, an ignition rod 25 is integrally provided on the bulkhead member 2 and is urged upward by a spring 26, the upper end of which is connected to the shaft 16 supported by the casing 1. It is pressed against the circumferential surface of a finger wheel 15 that is rotatably provided. Further, as is well known, the finger wheel 15 has an ignition stone disposed between a pair of wheel parts. Also, near this, an ignition handle 14 is rotatably supported around a shaft 13 which is also attached to the casing 1, and one end of the ignition handle 14 engages with the flame nozzle 17. Hook your finger on this other end 14a,
The gas lighter is configured to ignite when pressed.

The conventional gas lighter is constructed as described above, but by rotating the other end 14a of the ignition handle 14, where the finger rests, around the shaft 13 in the counterclockwise direction in the figure, the spring can be released. The shaft-shaped member 12 resists the spring force of 9.
is moved upwards in the diagram. As a result, the valve body 21 is separated from the valve seat 20 and the first gasification chamber 5 and the second gasification chamber 8 are communicated with each other. Therefore, the first gasification chamber 5 was now maintained at, for example, 2 atmospheres, but now that the valve body 21 is removed from the valve seat 20, the first gasification chamber 5 and the second gasification chamber 8 are
Due to the phase communication, the first gasification chamber 5 approaches atmospheric pressure, that is, the pressure becomes lower, and the liquefied gas, butane, is liquefied. At this time, the tube 3 is easily raised by pressing the liquid level with the above 2 atmospheres, and it is quickly vaporized due to the difference between the atmosphere and 2 atmospheres, and this gas passes through the small hole 18 provided in the shaft member 12. When the vaporized liquefied gas rises to the flame nozzle 17 through the shaft hole 12a and the ignition handle 14 is rotated with a finger, the finger wheel 1 is simultaneously rotated.
Since the ignition rod 25 is also rotated, the upper end of the ignition rod 25 pressed against the ignition rod 25 comes into sliding contact with the ignition stone, generating a spark, which ignites the vaporized liquefied gas generated from the flame nozzle 17. A flame F is generated. As is well known, the color of this flame is blue near the flame crater 17, and red above it.

Although conventional gas lighters are constructed and function as described above, there are times when it is desired to color the flame F.

Although conventional gas lighters are constructed as described above, there have been no examples of coloring the flame of gas lighters. However, there are the following examples of methods for coloring general gas flames.

For example, in ``Apparatus for Continuously Supplying Powder into a Flame'' disclosed in Japanese Patent Publication No. 54-13002, powder is stirred up in a gas by a stirring blade, transported by a gas flow, and guided to an ignition part. Powder particles are introduced into the combustion flame to color the flame. However, in this method, the particles are treated in the form of powder, and the finer the particles, the more pronounced the agglomeration becomes. Therefore, it is not possible to uniformly and continuously supply small particles such as ultrafine metal particles to the flame. If there is a large amount of agglomeration of particles, problems such as clogging of the gas lighter's flame opening and tube may occur. Further, it is impossible to incorporate a mechanism such as a stirring blade into a gas lighter because it requires space.

[0009] In addition to this, there is a ``method of coloring a gas flame'' disclosed in Japanese Patent Publication No. 2-38848.
An aqueous solution of a metal compound is mixed into the fuel gas in the form of a mist, and the mist is introduced into the combustion flame of the burner to color the flame. However, even with this method, the metal component to cause the flame color reaction is supplied into the flame in the form of an aqueous solution, and if a large amount of mist is supplied to color the flame more deeply, the temperature of the flame may drop, and sometimes Problems such as the flame dying out occur. Furthermore, in this mechanism, a fuel tank and a tank for an aqueous solution of a metal compound must be provided separately, making the mechanism complicated and requiring space, so that it cannot be applied to a gas lighter.

[Problems to be Solved by the Invention] The present invention has been made in view of the above problems, and an object of the present invention is to provide a gas lighter with a simple structure that allows coloring of the flame of a gas lighter, which has not been done in the past. do.

[0011]

[Operation] Ultrafine metal particles are mixed into the liquefied gas of the gas lighter, but it does not cause clogging, and it moves to the gas lighter's flame tinder in the form of a mist, so the gas lighter uses the flame color reaction. The color of the flame can be colored.

0012

[Means for solving the problem] The above object is to disperse ultrafine metal particles in the form of single particles in liquefied fuel gas, and to transport the ultrafine metal particles to the flame crater together with the vaporized gas of the liquefied gas. This is accomplished by a gaslighter, which is characterized by:

[0013]

[Embodiment] A gas lighter according to an embodiment of the present invention will be described below with reference to FIG. Note that parts corresponding to those in FIG. 2 of the conventional example are given the same reference numerals, and detailed explanation thereof will be omitted.

That is, in the gas lighter of this embodiment as well, the casing 40 is made of plastic, for example, and its interior is divided into an atmospheric chamber and a liquefaction chamber, which are defined by a partition wall 41. The liquefaction chamber is further divided into the first gasification chamber 34 and the liquefaction chamber 31 by a partition wall portion 41a that is a part of the partition wall 41, and the liquefied gas B
A tube 32 is immersed in butane, and its upper end protrudes into the liquefaction chamber 31, but the tip of the tube 32 is bent, and a nozzle 3 is attached to the end.
3 is formed. Further, the nozzle 33 faces a first gasification chamber 34, and this gasification chamber 34 is separated from a second gasification chamber 35 by a partition wall 41 as in the conventional example, and is normally separated by a valve body 21. It is blocked.

Furthermore, according to the present invention, ultrafine metal particles, for example ultrafine copper particles, are mixed in the liquefied gas B in a dispersed state.

The gas lighter according to the embodiment of the present invention is constructed as described above, and its operation will be explained next.

As with a conventional gas lighter, by operating the ignition handle 14 and driving the finger wheel 15, the valve body 21 attached to the lower end of the shaft member 12 is moved to the valve seat 2.
Leave from 0. Thereby, the liquefaction chamber 31, the first gasification chamber 34, and the second gasification chamber 35 communicate with each other. tube 3
2 is immersed in the liquefied gas B, and as in the past, the liquefaction chamber 31 is maintained at, for example, 2 atmospheres, so this pressure pushes up the liquefied gas B and moves it to the first gasification chamber 34. At the same time, since it is now in communication with the atmosphere, the pressure is lowered to the atmospheric pressure side, and therefore, liquefied gas is ejected from the nozzle 33 in a spray state, but at this time, it is uniformly dispersed in the liquefied gas B. The ultrafine copper particles that were in the state are transported together to the tube 32 and are sprayed from the nozzle 33 into the first gasification chamber 34 in the form of small particles. That is, it becomes a mist state, which flows into the second gasification chamber 35,
On the way, the liquefied gas in the mist evaporates and becomes a gas.Therefore, it becomes an aerosol with particles dispersed in the gas, which further passes through the small hole 18 of the shaft-like member 12 and through the hole 12a in the axial direction. As the finger wheel 15 is driven, a spark is generated, which is ignited to generate a flame Q. Now, since the metal ultrafine particles are copper, they exhibit a green flame reaction.

Further, according to this method, since the ultrafine metal particles have a particle size of 0.1 to 0.001 μm and are dispersed in the liquefied gas in the form of single particles, the temperature of the flame decreases and There are no problems such as clogging, and since ultrafine metal particles are mixed into the liquefied gas in the fuel tank, the mechanism is small and can be applied to gas lighters without any problems.

The ultrafine metal particles used in the present invention include, for example, Japanese Patent Application No. 1-1634 filed by the present applicant.
The method disclosed in No. 60 can be used. To briefly explain the contents, individual ultrafine copper particles are uniformly dispersed in an organic solvent, which is washed with a low boiling point solvent such as acetone or alcohol, and after removing the excess organic solvent, the low boiling point solvent is washed. Obtained by evaporation and drying. Since the surface of the ultrafine copper particles is coated with a suitable amount of surfactant, the particles do not adhere to each other even after drying, and the degree of aggregation is moderate, and this is added to the liquefied gas. The addition ratio was 1 part ultrafine copper particles to 100 parts liquefied butane by weight. When this mixed solution was shaken, the ultrafine copper particles were uniformly redispersed, the solution took on a transparent deep green color, and no aggregates were visually observed. In a combustion test in which about 10 cc of this mixed solution was actually put into a gas lighter, the flame turned green as mentioned above almost immediately after ignition, which was clearly different from the normal combustion color of butane. Similarly 100
Zero ignition tests were conducted, but no clogging occurred in the nozzle or flame tip.

Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, in the above embodiments, ultrafine copper particles were used as the ultrafine metal particles, but of course other metals such as strontium or chromium may also be used, or these particles may be mixed to create an intermediate color. The gas lighter can produce a flame of the desired color by exhibiting a known flame color reaction depending on each metal.

Furthermore, although butane was used as the liquefied gas in the above embodiments, the present invention is not limited to this, and various liquefied gases that are used in known gas lighters may be used.

[0023]

As described above, according to the gas lighter according to the present invention, a flame of a desired color can be generated without complicating the conventional structure.
