Abstract
The utility model provides a back and forth electric spark with long burning time and good appreciating. The utility model is characterized in that the inner part of an effect layer is provided with more than two layers of heat insulation films from outside to inside in sequence, and the head end of the corresponding effect layer is provided with an igniting gunpowder block, so that the effect layer is burnt back and forth according to the space determined by the heat insulation films to multiply extend the ornamental effect.
Description
Technical field
The utility model relates to line spices series products in a kind of fireworks industry, a kind of specifically electrical fire back and forth.
Background technology
Electrical fire is a kind of traditional firework product, belongs to line spices class firework product, as the technicolo blink, and sibilant rale electrical fire etc., its preparation method is that gunpowder is sticked to pole one end.When setting off, hand-held pole one end is lighted other end priming, and flame slowly fires tail end from head end.
The utility model content
The purpose of this utility model is to provide the electrical fire back and forth that a kind of burning time is long, have more appreciating.
The technical solution of the utility model is such, electrical fire back and forth, effect layer is arranged on pole one end, it is characterized in that: set gradually two-layer above thermal isolation film at the inner ecto-entad of effect layer, being provided with the ignition powder piece at corresponding effects layer head end, burns back and forth in the space that effect layer is determined by thermal isolation film.
Described thermal isolation film ecto-entad is followed successively by first thermal isolation film and second thermal isolation film, described effect layer ecto-entad is followed successively by first effect layer, second effect layer, the 3rd effect layer, is respectively equipped with the first ignition powder piece and the 3rd ignition powder piece at the head end of first effect layer and the 3rd effect layer.
Electrical fire back and forth of the present utility model is compared with the common electrical blink has following beneficial effect: the one, and the common electrical blink burns once, need expend a pole, the utility model can be realized many burnings back and forth on a pole, under comparing, more save a bar material.The 2nd, the common electrical blink is short burning time, and appreciation effect is single, and the utility model has prolonged appreciation effect at double by burning back and forth, uses different effect medicines, can set off two or more different effects on same electrical fire.
Description of drawings
Fig. 1 is the utility model preference structural representation
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, three electrical fires back and forth comprise pole 1, the three effect layer 2, the three ignition powder pieces 3, the second thermal isolation film 4, the second effect layers 5, the first thermal isolation film 6, the first effect layers 7, the first ignition powder pieces 8.When setting off, hand-held pole 1, light the first ignition powder piece 8, first effect layer 7 is seted off tail end from head end, because first thermal isolation film 6 leaves a bit of not sealing at tail end, second effect layer, 5, the second effect layers 5 fire head end from tail end so first effect layer 7 can ignite, rely on high temperate zone to fire the 3rd ignition powder piece 3, make the 3rd effect layer 2 fire tail end from head end.Whole combustion process is for once lighted a fire, and realizes three burnings back and forth.
Need to prove that thermal isolation film has heat-proof quality, but can burn with effect layer.Each effect layer, thermal isolation film, ignition powder piece pass through the method combination successively of adhesion, and are combined into global shape in pole.Electrical fire back and forth described in the utility model is meant that the electrical fire combustion efficiency shows as repeated combustion back and forth on same pole, can use different effect medicines at different effect layers, thereby realize two or more different firework display effects.
According to the technical scheme that the utility model provides, by two-layer above thermal isolation film is set, can design many electrical fires back and forth, these technical schemes belong to the claimed scope of the utility model equally.
Claims (2)
1. electrical fire back and forth, effect layer is arranged on pole one end, it is characterized in that: set gradually two-layer above thermal isolation film at the inner ecto-entad of effect layer, be provided with the ignition powder piece at corresponding effects layer head end, effect layer is burnt back and forth by the definite space of thermal isolation film.
2. electrical fire back and forth according to claim 1, it is characterized in that: described thermal isolation film ecto-entad is followed successively by first thermal isolation film and second thermal isolation film, described effect layer ecto-entad is followed successively by first effect layer, second effect layer, the 3rd effect layer, is respectively equipped with the first ignition powder piece and the 3rd ignition powder piece at the head end of first effect layer and the 3rd effect layer.
