The ignition means 50 is means for igniting the smokeless liquid fuel injected from the blowing nozzle 40. Specifically, as shown in FIG. 1, the ignition means 50 includes a nichrome wire 51 held at a position separated by a predetermined distance from the tip of the blowing nozzle 40, and an electric power supply for supplying a current to the nichrome wire 51. (Not shown).

When an electric current is applied to the nichrome wire 51 to heat it, the mist-like smokeless liquid fuel injected from the blowing nozzle 40 ignites and burns. Thereby, the blowing nozzle 4
From 0, a predetermined pattern of color fire FL is blown out.

The ignition means 50 may be formed by a burner 52 shown in FIG. A household propane gas cylinder (not shown) is connected to the burner 52 via, for example, a rubber supply pipe 54, and gas is supplied from the cylinder and a flame for ignition is emitted from an injection port 53. I have. In FIG. 3, reference numeral 55 denotes a metal tubular member for protecting the supply pipe 54.

Next, the operation of this embodiment will be described. By driving the compressor 31 to supply the smokeless liquid fuel from the storage tank 20 to the blowing nozzle 40,
When high-pressure compressed air is supplied to the nozzle 40 through the control air supply pipe 37, the smokeless liquid fuel is atomized from the blow-out nozzle 40 and is injected in a predetermined spray pattern. At this time, when the mistless smokeless liquid fuel is ignited by the igniting means 50, the liquid fuel is burned and a color fire FL of a predetermined pattern is generated.

As a result, each part of the tulip 7 (green leaves 7a, red petals 7b) appears, and a spectator in the spectator seat can appreciate the fireworks (tulip 7).

In this way, since the generated color fire FL is smokeless, the spectator can enjoy a clear color fire (tulip 7) without being disturbed by smoke even if the audience seat is downwind. it can. Note that the color fire FL lasts while the smokeless liquid fuel is being supplied from the storage tank 20 to the blow-out nozzle 40. You can appreciate it.

Thus, the storage tank 20 capable of storing the smokeless liquid fuel containing the flame colorant, and the smokeless liquid fuel supplied from the storage tank 20 via the supply means 30 are atomized to form a predetermined spray pattern. Since the jet nozzle 40 capable of jetting and the ignition means 50 capable of igniting the smokeless liquid fuel jetted from the jet nozzle 40 are provided, a smokeless color fire of a predetermined pattern can be provided for a long time (for example, 10 minutes or more).
Can be generated clearly.

Further, since the storage container is formed from the portable storage tank 20, the storage container (20) can be easily moved to a safe place according to the location restriction of the fireworks venue.

Since the fuel supply pipe 35 and the control air supply pipe 37 are rubber pipes, the blowing nozzle 40
Can be more easily installed without being restricted by these tubes (35, 37).

Further, since the rubber fuel supply pipe 35 and the control air supply pipe 37 in the vicinity of the blowing nozzle 40 are covered with the metal tubular members (36, 39),
Each rubber tube (35, 37) can be completely protected from the color fire FL blown out from the nozzle 40.
