Abstract
The utility model discloses an ignition head for a firework igniter, which comprises electric heating wire units (1) and two electrodes (2). The end portions of the electrodes (2) are bent to form clamping portions (21), and the electric heating wire units (1) are fixed in the clamping portions (21). The ignition head for the firework igniter has the advantages of being simple in processing technology, good in reliability, simple in structure, low in cost and wide in application range.
Description
Technical field
The utility model relates to the fireworks igniter, is specifically related to a kind of igniter head that is used for the fireworks igniter.
Background technology
Conventional sparking mode when setting off fireworks is manual firing closely, but this sparking mode is abnormally dangerous.In order to make people under safe distance, light fireworks, therefore the igniting of general at present employing remote control mode need use the fireworks igniter.
The fireworks igniter connects the igniter head that is used to light fireworks, and the igniter head that uses at present comprises lead, nickel chromium triangle heating wire and two-sided deposited copper circuit board, and wire bonds is on two-sided deposited copper circuit board, and the nickel chromium triangle heating wire is wrapped on the two-sided deposited copper circuit board.But,, have problems such as waste of material and wire bonds inconvenience in the production because the two-sided deposited copper circuit board area that igniter head needs is less; The nickel chromium triangle heating wire is difficult for welding in addition; The connected mode reliability of directly twining is bad; Therefore traditional igniter head has that structure is complicated, the technological process of production is complicated, generates that technology difficulty is big, reliability is bad and shortcoming such as not enough energy-conserving and environment-protective, has influenced the popularization and the use of fireworks igniters.
The utility model content
The technical problem that the utility model will solve provides that a kind of processing technology is simple, good reliability, simple in structure, igniter head that is used for the fireworks igniter that cost is low, applied widely.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of igniter head that is used for the fireworks igniter; Comprise Electrothermic wire unit and two electrodes, the end of said electrode is bent to form clamping part, and said Electrothermic wire unit is fixed in the said clamping part.
Further improvement as the utility model technical scheme:
Said Electrothermic wire is enclosed with the gunpowder layer on the unit.
The outside of said gunpowder layer is provided with protective layer.
Said Electrothermic wire unit comprises at least two Electrothermic wires that are arranged in juxtaposition.
Said Electrothermic wire is the nichrome resistance wire.
The utlity model has following advantage:
1, the end of the utility model electrode is provided with the clamping part that is bent to form; The Electrothermic wire unit is fixed in the clamping part, thereby realizes reliable connection the between Electrothermic wire unit and the electrode, does not need two-sided deposited copper circuit board and welding procedure; Practice thrift materials such as two-sided deposited copper circuit board and solder stick; Reduce technological process, processing technology is simple, be convenient to produce in batches, have good reliability, simple in structure, cost is low, the advantage of applied widely, energy-conserving and environment-protective.
2, the electrode of the utility model can link to each other with the fireworks igniter through lead, therefore both can be used for electronic type fireworks igniter, also can be used for laser type fireworks igniter, and is applied widely.

Marginal data: 1, Electrothermic wire unit; 2, electrode; 21, clamping part; 22, insulation sleeve; 3, gunpowder layer; 4, protective layer.
The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, igniter head that is used for the fireworks igniter of the utility model embodiment comprises Electrothermic wire unit 1 and two electrodes 2, and the end of electrode 2 is bent to form clamping part 21, and Electrothermic wire unit 1 is fixed in the clamping part 21.Electrode 2 comprises electrode 2a and electrode 2b in the present embodiment, and an end of Electrothermic wire unit 1 is fixed in the clamping part 21 of electrode 2a, the other end is fixed in the clamping part 21 of electrode 2b.
Be enclosed with gunpowder layer 3 on the Electrothermic wire unit 1.Because gunpowder layer 3 directly is wrapped on the Electrothermic wire unit 1, therefore responsive more to the heating of Electrothermic wire unit 1, can effectively improve the speed and the reliability of igniting.
The outside of gunpowder layer 3 is provided with the protective layer 4 of thinner thickness.Protective layer 4 adopts the resin damp-proof paint, thereby can prevent effectively that gunpowder layer 3 is loose, and protection gunpowder layer 3 is difficult for coming off from Electrothermic wire unit 1, but also can play the effect of damp proof insulation, can further improve the reliability of igniter head.
The fixed form of the similar ordinary incandescent lamp filament of the fixed form of Electrothermic wire unit 1 in the present embodiment; In processing; At first the end bending of copper conductor is come to form clamping part 21; The nichrome resistance wire of Electrothermic wire unit 1 is placed in the clamping part 21 of copper conductor side by side, compresses the clamping part 21 of copper conductor then, the nichrome resistance wire is clamped and fastened in the clamping part 21 and with clamping part 21 keeps in touch conducting.With Electrothermic wire unit 1 fixing after, gunpowder is wrapped in forms gunpowder layer 3 on the nichrome resistance wire, on gunpowder layer 3, coat protective layer 4 again, can make igniter head of present embodiment.Present embodiment in use; Electrode 2 is connected conducting through lead with the output of fireworks igniter; When the output output current of fireworks igniter, the nichrome resistance wire that electric current flows through Electrothermic wire unit 1 produces Joule heat, and the gunpowder layer 3 that is wrapped on the nichrome resistance wire is lighted; Burn outer thin protective layer 4, then fireworks are ignited.
The above only is the preferred implementation of the utility model, and the protection domain of the utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to the protection domain of the utility model.Should be pointed out that for those skilled in the art in the some improvement and the retouching that do not break away under the utility model principle prerequisite, these improvement and retouching also should be regarded as the protection domain of the utility model.
