JP3116627U - Flying fireworks immediate igniter - Google Patents

Abstract

An object of the present invention is to ignite with high heat when burnt off a nichrome wire by energization, thereby enabling immediate ignition. In addition, by making it possible to easily replace the nichrome wire that burns out at the time of ignition, it is easy to perform the launch control, and an inexpensive flying fireworks immediate igniter is provided.
A nichrome wire 1 that is inserted into a gunpowder of a flying fireworks and is instantaneously burned off by energization is bridged to an electrode 2 and combined with a socket 3 connected to a core wire at one end of a power line 4 and fixed. The nichrome wire 1 burned after ignition is exchanged with the electrode 2.

Description

  The present invention relates to an igniter that instantly ignites flying fireworks using a nichrome wire.

  In the past, flying fireworks have been ignited through a lead wire attached to the fireworks using fire types such as matches, lighters, incense sticks, and candles. As an apparatus for igniting without using a fire type or a conductive wire, a pyrotechnic igniter and a method for producing flying fireworks applied to this apparatus (see Japanese Patent Application Laid-Open No. 08-075399) are ignition apparatuses using an electric heater.

  When performing the flight control of flying fireworks, the conventional ignition method using a fire type and a conductive wire causes a delay or variation in the ignition time of the explosive, and it is difficult to adjust the ignition timing. In addition, the conductors attached to commercial fireworks are unreliable and can cause poor ignition.

  In the case of performing ignition and firing control of flying fireworks with the heat of the electric heater, it is necessary to design in advance assuming a delay from energization to reaching the ignition temperature. Therefore, the mechanism of the device itself is complicated and expensive. In addition, since it is assumed to be reused, the temperature becomes such that the heater does not deteriorate, and it is difficult to reliably ignite the explosive.

  In the present invention, nichrome wire is burned out instantaneously with a relatively high electric power, and the high temperature enables the gunpowder to be immediately ignited without going through the lead wire. Furthermore, the nichrome wire part to be burned out is made into a detachable module so that quick and inexpensive replacement is possible.

  The invention described in claim 1 is a flying fireworks quick igniter in which a socket fixed in combination with a core wire at one end of a power line is connected to an electrode formed by bridging a Nichrome wire formed into an inverted U-shape. Is inserted into the gunpowder tube of the flying fireworks from which the lead wire is removed, burned out instantaneously by the power of the power source for the electric light, and the gunpowder is immediately ignited by the high heat.

  The invention described in claim 2 is the flying fireworks immediate igniter according to claim 1, wherein the electrode and the Nichrome wire cross-linked to the electrode are modularized, and the power line is detachable by a socket. The burned-out module can be replaced quickly and inexpensively.

  According to the first aspect of the present invention, the nichrome wire is burned out instantaneously with the power equivalent to the power source for electric lamps, and the explosive in the flying fireworks can be ignited immediately and reliably by the high heat. Therefore, it is possible to provide an igniter that is highly applicable to launch control and the like.

  According to the second aspect of the present invention, the module burned out by energization is removed from the socket and replaced with a new one, so that it can be used again for ignition. Therefore, an igniter that can be repeatedly used at low cost can be provided.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention. The present invention comprises a module in which a nichrome wire 1 is bridged to an electrode 2 and a power line 4 having a socket 3. FIG. 2 is a partially cutaway cross-sectional view of the present invention showing the relationship and structure of the electrode 2 and the socket 3. The nichrome wire 1 having a diameter of about 0.3 mm and a length of about 30 mm is formed into an inverted U shape, and is bridged and fixed to the female side of the pin socket used as the electrode 2. Also, a vinyl flat cord is used as the power line 4, and the male side of a high male type pin socket is inserted and fixed as a socket 3 at one end thereof. The length of the power line is adjusted according to the environment where ignition is performed. And the whole is comprised by connecting the electrode 2 of a module to the socket 3. FIG.

  Insert the device, fixed with a prop, etc., into the pyrotechnic cylinder of the flying fireworks with the lead wire removed, and let the gunpowder and nichrome wire contact each other. The other end of the power line is connected to a power source via a switch, a relay, or the like.

  In the present invention, when energized, the nichrome wire 1 burns out instantaneously, and the gunpowder is ignited by the high heat. After ignition, the nichrome wire 1 burns out, so the entire electrode 2 can be removed from the socket 3 and replaced with a new module so that it can be used for ignition again.

  Since the present invention electrically ignites the flying fireworks, it is easy to control the launch using an electronic device or a computer. Further, since ignition without delay is possible without using a lead wire, it is possible to launch in synchronism with music.

  It has a simple structure and uses consumer products, so it is highly reliable and it is easy to obtain consumable parts. As a result, it can be produced inexpensively and quickly, and is suitable for mass consumption. Furthermore, it is possible to use at low running cost by making it possible to replace only the part that burns out during ignition.

It is a perspective view which shows one Example of this invention. It is a figure which shows the relationship and structure of the electrode 2 and the socket 3 with the partially cutaway sectional view of this invention.
