Abstract
The utility model discloses single-shot firework with a separated electrical igniter, which comprises a cylinder, a bottom plug, a propellant powder layer, a fire pad, an effective gunpowder layer and a sealing cover plate, wherein a channel communicated with the propellant powder layer is arranged on the bottom plug, and a through hole is arranged on the cylinder corresponding to the channel. In the process of storage and transportation, the electric igniter and the fireworks are separately placed, and the electric igniter is inserted in the through hole and the channel to ignite the effective gunpowder layer when the firework is set off. The utility model has the advantages of safe storage and transportation, convenient production and use and less setting-off pollution, and omits the fuse igniting link of the original product simultaneously, thereby the ignition reliability is greatly strengthened, and no ignition fuse residue falls on the ground.
Description
Technical field
The utility model relates to a kind of single-shot firework product, the especially igniter of single-shot firework product.
Background technology
Tradition single-shot firework product (as brave tail, bouquet, stage fireworks etc.) is by cylindrical shell, mud (wood) bottom plug, propellant powder layer, the pad that overdoes, effect medicine layer, capping plate and ignition fuse thereof and electric ignition is first-class forms.Its ignition fuse and electric igniter all are fixedly to be assembled into one with the fireworks main body aborning, have the unsafe factor of mistake combustion in transportation and storage process; Simultaneously traditional product is lighted ignition fuse by electric igniter, and by the ignition fuse propellant powder that ignites, ignition fuse is drawn outside the cylindrical shell again, not only the finished product outward appearance is not attractive in appearance, and, reduced the reliability of igniting, the drawback that also exists the ignition fuse residue to land because the ignition process link is more; Moreover traditional product propellant powder large usage quantity produces big smog harmony and rings when setting off, caused the pollution of environment.When existing product adopts more wooden bottom plug to assemble in addition,, to hammer into three mouthfuls of iron nails at least and reinforce, exist assembling to produce inconvenience for fear of coming off with cylindrical shell, the shortcoming that labour intensity is big,
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved in the utility model is, the single-shot fireworks that provide a kind of electric igniter to split, its igniting is reliable, the storage transportation safety is produced, easy to use, set off pollute less.In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, the single-shot fireworks that a kind of electric igniter splits, comprise cylindrical shell, bottom plug, propellant powder layer, the pad that overdoes, effect medicine layer, capping plate, described bottom plug is provided with the passage that connects with the propellant powder layer, is provided with through hole with the corresponding position of described passage on described cylindrical shell, in the storage transportation, electric igniter separates packing with fireworks to be put, and electric igniter can insert and the effect medicine layer that ignites from described through hole and passage when setting off.
As a kind of improvement of the present utility model, the single-shot fireworks that described electric igniter splits also comprise the pin pipe of being with mesopore, and described pin pipe is nested in described through hole and the passage.Its role is to strengthen fixedly bottom plug and on cylindrical shell, avoid bottom plug to come off, avoid the passage dislocation of the through hole and the bottom plug of cylindrical shell simultaneously, guaranteed that the insertion passage of electric igniter connects.
As another kind of improvement the of the present utility model, the described pad that overdoes is provided with cylindric edge, closely is nested in the described cylindrical shell.The described pad that overdoes cooperates with bottom plug, the pressure when having increased the propellant powder detonation, and the propellant powder consumption of the product of same specification obviously reduces, and has reduced the smog and the sound when setting off, has protected environment.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

The specific embodiment
Referring to accompanying drawing, reflect a kind of preferred concrete structure of the present utility model, wherein Fig. 1 is an outside drawing, 1 time end device pin of cylindrical shell pipe 2, pin pipe outer 22 is pressed on the cylindrical shell 1, and pin pipe mesopore 21 is used to insert the electric igniter of spaced apart.Hatching A-A
1Pass central point of hole in the pin pipe.Please in conjunction with Fig. 2-Fig. 8, described single-shot fireworks comprise cylindrical shell 1 and gluing in the bottom plug 8 of cylindrical shell 1 bottom, are followed successively by propellant powder layer 7 on the bottom plug 8, pad 6, effect medicine layer 5, capping plate 4 overdo.Described bottom plug 8 is with polypropylene or polyethylene material pressed sizing, which is provided with the passage 82 that connects with propellant powder layer 7, passage 82 terminal and propellant powder layer 7 perforation, perforation place propellant powder injects, form igniting chamber 81, be provided with through hole with the corresponding position of described passage on described cylindrical shell 1, pin pipe 2 inserts and is nested in it from described through hole and passage 82, and sticks with glue fixing.Electric igniter self-marketing pipe mesopore 21 inserts, after the energising, at the contact of igniting chamber 81 places and the propellant powder layer 7 that ignites, propellant powder layer 7 is lighted the back and is crossed the fire holes 61 effect medicine layer 5 that ignites by pad a plurality of on 6 that overdo, the immense pressure of propellant powder detonation simultaneously promote to overdo pad 6 and effect medicine layer 5 launches, and shows gorgeous fireworks moulding.The tubular edge 62 of pad 6 closely is nested in the cylindrical shell 1 owing to overdo, the pressure when having increased 7 detonation of propellant powder layer, and the highly required emission dose of same lift-off significantly reduces, and has reduced and has seted off pollution.
In sum, the single-shot fireworks that the electric igniter that the utility model provides splits, its transportation safety of storing in a warehouse is produced, easy to use, set off pollute less.Simultaneously, it has omitted lead-in wire igniting link of existing product, and the igniting reliability is strengthened greatly, and does not have the ignition fuse residue and land.Realized goal of the invention fully.
The above-mentioned embodiment that the utility model is described only is for the technical solution of the utility model clearly is described, and can not be interpreted as the utility model is made any restriction.The utility model has known multiple alternative or distortion in the present technique field, under the prerequisite that does not break away from the utility model essential meaning, all fall into protection domain of the present utility model.
