Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an indoor candle firework in which a candle and a firework are continuously ignited through a squib.

[Problems to be Solved by Description and Invention of Prior Art] In recent years, a candle service has been adopted in order to enhance the effect of production at wedding receptions and the like. In addition, there is a desire to use fireworks as a means of enhancing the effect of rendering indoors.
However, the composition of fireworks consists of a mixture of an oxidizing agent, an auxiliary combustion agent, a sparkling agent, a flame-coloring agent, and a paste, and the mixture is dried. Then, burned dust is scattered. For this reason, when fireworks are performed at an indoor venue such as a reception party, there is a risk that the smoke or the smell of a firework may fill the room or burned dust may scatter into the room, ruining the reception party.

In addition, since the fireworks composed of this composition are strongly solidified with glue, a strong firepower is required to ignite the fireworks.Therefore, it is not possible to ignite multiple fireworks continuously with a fuse in a room. was there.

In recent years, a fireworks composition containing nitrocellulose as a main component has been developed as an agent for extremely reducing the generation of smoke, scent and smell of burning dust. However, the fireworks containing nitrocellulose as a main component have an extremely short burning time, so that they tend to lack swelling.

[Purpose of the Invention] This invention is to continuously ignite a candle and fireworks through a squib, to reduce smoke, foul odor, and residual dust after the fireworks are burned, and to lengthen the fireworks burning time. However, it is an object of the present invention to provide an indoor candle firework in which ignition by a fuse is surely performed.

[Means for Solving the Problems] In order to achieve the above object, the present invention has a candle and a firework obtained by applying nitrocellulose as an ignition material on the surface of a metal rod-shaped member, The ignition part of the candle and the upper part of the nitrocellulose of the fireworks in an upright state are connected by a squib.

[Operation] Since the nitrocellulose is attached to the metal rod-shaped member having high thermal conductivity, the metal rod-shaped member absorbs the heat generated during combustion to prolong the burning time of the fireworks. Furthermore, since the squib is connected to the upper part of the nitrocellulose in the standing state, this also prolongs the burning time of the fireworks. Since it is a firework composed mainly of nitrocellulose, it produces almost no smoke, foul odor, and residual dust, and nitrocellulose ignites at a low temperature, so it is easily ignited through a squib.

[Embodiment] Next, the present invention will be described with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the indoor candle fireworks of the present invention, and FIG. 2 is an enlarged sectional view showing the combustion state of the fireworks.

The indoor candle fireworks 10 includes a candle 14 standing on a candle support 12 and the candle support 12 described above.
The fireworks 18 standing on a plurality of firework holders 16 provided adjacent to the candles 14 and the fireworks 1
8 is connected by a squib 20. In this indoor candle, a plurality of fireworks 18 are generally arranged with a proper interval centering on one candle 14.

The fireworks 18 is composed of an elongated wire-shaped rod-shaped member 22 and a pyrotechnic material 26 whose main component is nitrocellulose applied to the surface of the rod-shaped member 22 excluding one end 24. The pyrotechnic material 26 containing nitrocellulose as a main component produces almost no smoke or odor, and has almost no residual dust. Moreover, it ignites at a lower temperature than conventional fireworks compositions. This fireworks 18 is a rod-shaped member 2.
A support tube 28 provided with the end 24 of the second part on the firework holder 16.
The fire wire 20 is erected by being inserted into the fireworks material 26 at a position which becomes the upper end in the erected state.
Glue.

The ignition member 30 is slidable with respect to the squib 20.
Is attached. Like the pyrotechnic material 26, the ignition member 30 is made of nitrocellulose and has a cap shape so that it can be attached to the core of the candle 14.

According to the indoor candle fireworks 10 configured as described above, the fire ignited on the ignition member 30 burns the ignition member 30 for about 8 seconds, and the ignition member 30 is ignited on one side of the candle 14. The core ignites, and the other propagates through the squib 20 and ignites the pyrotechnic material 26 at the upper end of the fireworks 18.
Since the pyrotechnic material 26 is made of nitrocellulose that is ignited at a low temperature, the pyrotechnic material 26 is surely ignited by the fire transmitted through the squib 20. Then, the fire ignited at the upper end of the pyrotechnic material 26 burns the pyrotechnic material 26 in order from above to below. Since the pyrotechnic material 26 is applied to the surface of the rod-shaped member 22 having good heat conductivity, the rod-shaped member 22 releases the heat of the fire that burns the pyrotechnic material 26. In this way, the combustion time of the pyrotechnic material 26 can be extended by the combustion from above the pyrotechnic material 26 to the downward direction and the release of heat by the rod-shaped member 22. For example, when the fireworks material 26 has a length of 12 cm and an outer diameter of 4 mm, the fireworks burn for about 1 minute 10 seconds. As a result of the long burning time, the atmosphere of a reception or the like can be further enhanced.

The pyrotechnic material 26 and the ignition member 30 which are mainly composed of nitrocellulose do not fill the room with smoke or a scent of kina and do not scatter the remaining dust when burned, so it is a bright place such as a wedding reception or a party. Not only can it be enjoyed at home.

By connecting and fixing a plurality of fireworks 18 with a squib 20 and attaching an ignition member 30 for covering the wick of the candle 14 on the squib 20, the fireworks 18, the squib 20 and the ignition member 30 excluding the candle 14 are attached. It can be sold only by the product consisting of and, and can meet the needs of customers. At that time, if the ignition member 30 is displaceably attached to the squib 20, even if the distance between the candle support 12 and the firework holder 16 is slightly different, it can be applied.

In the above embodiment, the number of fireworks 18 is two and each of the fireworks 18 is connected to the candle 14. However, the number of the fireworks 18 is increased and the fireworks 18 are connected to the fireworks 18 by the fuse 20. It may be done.

The pyrotechnic material 26 and the ignition member 30 made of nitrocellulose may be mixed with a spark agent, a flame colorant, or the like.

[Effects of the Invention] As described above, according to the indoor candle fireworks according to the present invention, the candle and the fireworks can be continuously ignited through the squib, and smoke, a foul odor, and residual dust are generated when the fireworks burn. In addition, the fireworks are burned for a long time, and it is possible to reliably ignite the fireworks from the squib.
