Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flame ejecting device for special effects, which is suitable for shooting a movie or for blowing up a flame at various event venues.

[0002]

2. Description of the Related Art Recently, at an event venue or the like, it is often practiced to blow a flame into the sky to make the place lively. In this case, the higher the thick flame, the more
The effect of the effect becomes large. Therefore, in order to improve the effect, a strong fire power is absolutely necessary. Therefore, conventionally, as shown in FIG. 2, a bag 2 containing gasoline is placed in an iron container 1, and an explosive powder 3 is placed under the bag 2. I was trying to burn the gasoline inside while atomizing it. Therefore, the direction or form of atomization of this gasoline matches the direction of rise of the flame or its form.

[0003]

In the conventional device as described above, the direction or mode of spraying of gasoline is not always constant depending on the situation of setting explosives. For example, when gasoline is scattered around, There were even high flames that didn't fly up. However, in order to scatter the gasoline in the desired direction, it depends on the size of the container 1 and the amount of gasoline, or the setting condition of the bag 2 containing the gasoline and the gunpowder 3, etc. There was a problem that I could not.

Further, not only is gasoline not neatly sprayed, but it may be blown to the ground as a lump. When gasoline lumps scatter on the ground in this way, it is natural that the flames will be scattered around, which poses a very dangerous situation and also requires a fire extinguishing activity. In any case, with this conventional one, the desired flame could not be stably produced, and failure was unavoidable. Since it is unavoidable to make a mistake, it can hardly be used at the demonstration venue, and even if it can be done, for details such as the size of the container and the amount of gasoline, the setting condition of the bag with gasoline and gunpowder, etc. There has been a problem that it requires a great deal of attention, and that much setting work takes much time.

As described above, for each setting,
Since it takes a lot of time, it was difficult to use it continuously. Therefore, there is a problem in that it cannot be used to continuously blow up the flame to enhance the effect. An object of the present invention is to provide a flame producing device for special effects which allows anyone to easily produce a desired flame and can be safely and continuously used.

BEST MODE FOR CARRYING OUT THE INVENTION The embodiment shown in FIG.
In addition, four fuel tanks 12 are rotatably provided at symmetrical positions. That is, hinges 14 and 14 are provided on each of the four fuel tanks 12, and the four fuel tanks can be rotated around the hinges with respect to the pedestal 11 and fixed at arbitrary rotation positions. I am able to do it. Further, the body 13 of the solenoid valve V is fixed to each of these four fuel tanks 12. Therefore, the angle of the solenoid valve V can be adjusted by rotating the fuel tank 12. The fuel tank 12 is connected via a hose 15 to a cylinder for compressed fuel (not shown).

On the main body 13 of the solenoid valve V, a flame arrester 16 which is a flashback valve for preventing the flame from being guided to the fuel tank 12 is fixed. The fuel injection nozzle 17 is fixed on the flame arrester 16. That is, this fuel jet nozzle 1
7 is provided in each of the four fuel tanks 12, and a total of four devices are provided. Moreover, these four nozzles 17 are provided at equal intervals on the circumference and rotate integrally with the main body 13, the flame arrester 16 and the fuel tank 12 of the solenoid valve V,
The angle can be adjusted freely. The hinge 14 provided on the fuel tank 12 serves as a main element to configure an angle adjusting mechanism for adjusting the angle of the fuel injection nozzle 17.

Further, an air hole (not shown) is formed in the fuel injection nozzle 17 so that the opening of the air hole can be freely adjusted. The fuel jet nozzles 17 are attached to the gantry 11 provided with the fuel jet nozzles 17 as described above.
The fire seed generating means 18 is provided at the center of the arrangement, which is a position equidistant from. A support rod 19 is provided at the lower end of the fire type generating means 18, and the support rod 19 slidably penetrates into a bearing 20 provided on the mount. The height of the fire type generating means 18 as described above can be freely adjusted by pushing the supporting rod 19 into the bearing 20 or pulling it from the bearing 20. Therefore, the support rod 18 and the bearing 19 constitute an adjusting mechanism for adjusting the height of the fire type generating means 17.

Next, a case where a flame is generated by using the apparatus of this embodiment will be described. First, the hose 15 is connected to a cylinder (not shown) filled with compressed fuel to fill the fuel tank 12 with the compressed fuel in the cylinder. The fuel at this time may be gas or liquid. After the fuel tank 12 has been filled with fuel as described above, the ignition source 18 is ignited this time, and a flame as an ignition source is established from there.

After establishing a flame as a fire source, the solenoid valve V is opened and the compressed fuel in the fuel tank 12 is vigorously ejected from the fuel ejection nozzle 17. The fuel ejected from the fuel ejection nozzle 17 is ignited by a flame,
It is blown up vigorously. By blowing up the ignited fuel in this way, the flame is blown up in a desired direction in a high sky.

In the present invention, the number of nozzles is not necessarily limited. 1 or 4
It may be more than a book. However, in the case of one, there are the following problems, so four or more are ideal if possible, and the reason is as follows.

For example, if there are four or more fuel injection nozzles 17, there is a merit that ignition is likely to occur even in a windy place. If there is only one fuel ejection nozzle 17, the fuel ejected from the fuel ejection nozzle 17 may flow in a direction away from the ignition source depending on the wind direction, and thus ignition may not be possible. However, if there are four fuel ejection nozzles 17, the fuel ejected from at least one nozzle 17 will come into contact with the fire regardless of the direction in which the wind blows. In this way, if only one nozzle 17 is ignited, the fuel of the other nozzle 17 is also ignited accordingly. Therefore, it is possible to always ignite regardless of the direction of the wind.

Further, the relative relationship between the fuel injection nozzle 17 and the ignition type generating means 18 is as follows. That is, the opening of the ignition source 18 is below the ejection port of the fuel ejection nozzle 17, and the fuel ejected from the fuel ejection nozzle 17 is ejected so that the flame of the ignition unit 18 may be absorbed. Ideally. If the fuel ejected from the fuel ejection nozzle 17 is directly applied to the flame, the flame is extinguished by the momentum when the fuel is ejected, and the fuel from the fuel ejection nozzle 17 cannot be ignited. Therefore, from the viewpoint of ignition, it is preferable that the opening of the fire type generation means 18 be located below the ejection port of the fuel ejection nozzle 17. For this reason, the height of the fire type generating means 18 may be freely adjusted as described above so as to maintain an ideal relationship.

The height of the flame formed by this apparatus is determined by the pressure of the fuel with which the fuel tank 12 is filled, the angle of the fuel injection nozzle 17, the mixing ratio of fuel and air, and the like. The mixing ratio of the fuel and air can be adjusted by increasing or decreasing the opening of the air hole.
The angle of the fuel injection nozzle 17 can also be adjusted freely. The height of the flame can be lowered as the fuel jet nozzle 17 is tilted. On the contrary, the higher the fuel injection nozzle 17 is raised, the higher the flame height can be made.

Further, as described above, the fuel injection nozzle 17
If four nozzles are installed at equal intervals and the nozzle 17 is ignited,
An ascending air current is generated below the flame, which also causes the flame to be blown up high in the sky. The generation of this rising air flow also depends on the angle of the fuel injection nozzle 17.
In any case, if the jetting direction of the fuel jetted from the fuel jet nozzle 17 and the extension line of the flame of the fire seed generating means 18 intersect each other, the fuel jetted from the fuel jet nozzle 17 will be ignited. Become. Then, in order to adjust the height of the flame and the like, the angle of the fuel injection nozzle 17 may be adjusted.

Further, the solenoid valve V can inject or stop fuel from the fuel injection nozzle 17 by opening and closing it. A so-called fire ball can be made by opening the solenoid valve V and then closing it. The fire ball is a flame like a round ball, and the fire ball can be made by opening the solenoid valve V and closing it as described above. And if the opening and closing of the solenoid valve V is repeated in a short time,
You can make several fire balls in a row. Therefore, depending on the purpose, the staging effect can be further emphasized.

In the above embodiment, the fuel injection nozzle 17 is rotated together with the solenoid valve V and the flame arrester 16 to adjust its angle. However, with respect to the angle adjustment, any configuration may be used. It doesn't matter. In short, any mechanism can be used as long as the angle of the nozzle can be freely changed as needed. The same applies to the adjusting mechanism that adjusts the height of the fire type generating means 18. That is, any structure may be used as long as the height can be adjusted.

[0020]

According to the apparatus of the first aspect of the present invention, a flame can be easily created by ejecting the compressed fuel from the fuel ejection nozzle while the ignition source is provided with an ignition source. There, it is neither difficult nor dangerous as in the past. Therefore, it can be used safely even in a demonstration hall. Also, just by filling the fuel tank with fuel, you can immediately create a flame, so once you create a flame,
If the fuel tank is immediately filled with fuel, the flame can be continuously blown up.

According to the apparatus of the second aspect of the invention, since the plurality of fuel injection nozzles surrounds the fire seed generating means, for example,
The fuel injection nozzle can be ignited even in the wind. Further, the fuel injected from the fuel injection nozzle is ignited to form a flame, and the ascending air current at that time acts synergistically to further increase the height of the flame. In other words, since the center of arrangement of each nozzle is surrounded by the upward airflow due to the flames ejected from the individual nozzles, the momentum of the upward airflow is further increased. The action of the ascending air current thus increased further increases the height at which the flame is launched. In other words, the height of the flame depends on the pressure of the fuel tank, the angle of the fuel injection nozzle, etc., but the height of the flame can be increased due to the structural factor of the device of the second invention.

According to the device of the third aspect of the invention, the fire is not extinguished by the force of the fuel ejected from the fuel ejection nozzle. Therefore, it is possible to always ignite stably. According to the device of the fourth invention, the momentum of the flame can be adjusted while adjusting the amount of air introduced into the fuel injection nozzle. According to the device of the fifth invention, the height of the flame can be freely adjusted by adjusting the height of the flame generation means and the angle of the fuel injection nozzle without extinguishing the flame.

According to the apparatus of the sixth invention, the timing of flame generation can be freely adjusted by opening and closing the solenoid valve. A so-called fire ball can also be made by opening the solenoid valve and then closing it. That is, the timing of flame generation and the flame form can be freely determined.
