Abstract
The utility model discloses a fireworks cylinder for spraying fireworks, which consists of a cylindrical body and an ignition device. The inner cavity of the cylindrical body is provided with an upper sealing cylinder, a lower sealing layer and a gunpowder layer. The upper sealing layer is provided with a fire spraying hole arranged on the position deviating from the axis of the cylindrical body and closes to the wall of the cylindrical body. The gunpowder layer corresponding to the fire spraying hole is provided with a through hole from the top to the bottom. A position, in which the gunpowder is ignited, is arranged inside the through hole of the gunpowder layer. The product with the utility model can control accurately the firing time, and has the advantages of simplicity, easy operation and low cost.
Description
Technical field
The utility model relates to spraying decoration class fireworks, the roman candles of especially spraying decoration class fireworks.
Background technology
Along with the raising of people's living standard, the design of igniting fireworks becomes increasingly complex changeable, and often interts with other theatrical items and carry out, and plays the effect of good heighten atmosphere.But just because of this, product being seted off the accuracy of time span also has higher requirement, particularly when a plurality of same spraying decoration product mixes are seted off, same product is lighted simultaneously, if the time of setting off is inconsistent, the time that finishes is variant, can not accomplish uniformly, then can cause very big destruction to the firework display effect of product.
By discovering, setting off time length and ignition position has very big relation.The fire jetting hole of effect tube of the prior art (also being vent simultaneously) is all got the shaft core position of cylindrical shell, after product is lighted, the burning-point that is positioned at the medicine layer centre of surface is to igniting downwards all around, the time of setting off depends primarily on the height of medicine layer, and multiple factors such as the quality of while and medicine layer, density, state all have complicated relation.But the production of firework also has very big hand labour composition, can't realize that above-mentioned factor is fully accurately consistent.So the control to the time of setting off is difficult to reach requirement.Therefore, a kind of time of setting off of market demand can accurately be controlled now, sets off the spraying decoration product of time unanimity to guarantee a plurality of products.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, and a kind of roman candles of spraying decoration class fireworks are provided, and the time of setting off can accurately be controlled, and sets off the spraying decoration product of time unanimity to guarantee a plurality of products.
In order to realize the foregoing invention purpose, the technical scheme that the utility model is taked is, a kind of roman candles of spraying decoration class fireworks, form by cylindrical shell and igniter, cylinder lumen is established upper and lower sealing layer and gunpowder layer, last sealing layer is provided with fire jetting hole, and described fire jetting hole is located at and departs from the position of cylindrical shell axle center near barrel wall.The position of the corresponding fire jetting hole of described gunpowder layer is provided with through hole from top to bottom.The position of lighting gunpowder is located in the gunpowder layer through hole.
Adopt the roman candles of technique scheme, through hole is located at and departs from the position of barrel wall axle center near barrel, has limited and has ignited direction and control the speed of igniting.The consistent gunpowder that helps with through hole in fire jetting hole position sprays.Ignition location is located in the gunpowder layer through hole, and near the gunpowder the through hole can at first be lighted, and is standard shaft parallel propelling on the cylindrical shell cross section then with the through hole.When a plurality of spraying decorations are seted off simultaneously, as long as guarantee that the lead to the hole site of each spraying decoration is consistent with the cylindrical shell cross section, fire to the time of barrel opposite side basic identically, just can realize accurate control to the time of setting off, simple and easy to do.Very little to the adjustment and the modification of existing firework production technology simultaneously, production cost can not increase yet.Realized goal of the invention fully.
As a kind of optimum embodiment of the present utility model, the minimum range that fire jetting hole is located at hole week back gauge barrel wall is 2 millimeters position.This moment, not only effect was best, and production technology is preferably control also.
As a kind of optimum embodiment of the present utility model, described igniter adopts electric duration and degree of heating igniting.Convenient control igniting.
As the further improvement of a kind of embodiment on the utility model, the ignition location of described electric duration and degree of heating is located at the middle part of gunpowder layer through hole.Can further reduce the error of the time of setting off.
Another kind as a kind of embodiment on the utility model improves, and the harness of described electric duration and degree of heating is introduced from the lower sealing layer.Reduce the inhibition that lead sprays gunpowder to greatest extent.
As the another kind of embodiment of the utility model, described firing device adopts the lead-in wire igniting.

The specific embodiment
Referring to Fig. 1, roman candles are made up of cylindrical shell 1 and lead-in wire 2, cylindrical shell 1 inner chamber is established sealing layer 4, lower sealing layer 6 and gunpowder layer 5, last sealing layer 4 is provided with fire jetting hole 3, fire jetting hole 3 is located at and departs from the position of cylindrical shell 1 axle center near barrel wall, the position of gunpowder layer 5 corresponding fire jetting hole 3 is provided with through hole 7 from top to bottom, and the position of lighting gunpowder is located in the through hole 7.
Referring to Fig. 2, the minimum range that fire jetting hole 3 is located at hole 3 all back gauge barrel walls 8 is 2 millimeters position.All the other are identical with last example.
Referring to Fig. 3, the harness of electric duration and degree of heating 9 is introduced from lower sealing layer 6, and the position of lighting gunpowder is located at the middle part of through hole 7.All the other are identical with first embodiment.
