Improved structure of Roman candle firework

Abstract

The invention discloses an improved structure of the Roman candle firework. The improved structure is characterized by comprising an outer cylinder with a base and an upper cover, effect inner cylinders sequentially arranged in the inner cavity of the outer cylinder and filled with effect medicines, lift-off charge arranged below each effect inner cylinder in a filling mode, and paper arranged between each effect inner cylinder and the lift-off medicine and provided with fire holes. A flame retardant is arranged at the upper end of each effect inner cylinder. The flame retardant is composed ofthe paper layer, a separation layer and a flame-retardant layer, wherein the paper layer, the separation layer and the flame-retardant layer are sequentially combined to form an integral cylinder structure. A buffer layer is arranged at the bottom end of the outer cylinder. A lead wire respectively penetrates the lift-off medicine, the paper and the fire retardant to be connected with each effectinner cylinder in series. According to the invention, every two adjacent effect inner cylinders are tightly blocked from each other, so that the shooting power required by the effect inner cylinder is guaranteed. As a result, the phenomena of fire bunching and cylinder blowout are completely eradicated. The setting-off effect is good.

Description

Technical field [0001] The invention relates to an improved structure of Roman candlelight fireworks, belonging to the technical field of fireworks products. Background technique [0002] In the prior art, the barrel of Roman candlelight fireworks is filled with multiple effect inner barrels. When the multiple effect inner barrels are lifted into the air step by step, they can present multiple effects of sound, light, and color. It can also set off a combination of multiple cylinders. Its lighting effects are rich and colorful, and it is deeply loved by consumers. However, because there is only one paper bar between the two adjacent effect inner cylinders, when setting off , Due to the imperfect barrier of the paper, it is easy to tilt or deform, causing crossfire, bombing, and other phenomena, which affects the effect of setting off. Summary of the invention [0003] In view of the above technical problems, the purpose of the present invention is to provide an improved structure...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, the barrel of the Roman candlelight fireworks is filled with multiple effect inner barrels, and the multi-effect inner barrels are lifted up step by step during the discharge, which can present multiple discharge effects of sound, light, and color. It can be used to discharge single-body products, and it can also discharge combined products with multiple cylinders. Its discharge effect is rich and colorful, and it is deeply loved by consumers. , because the paper is not tightly blocked, it is easy to tilt or deform, resulting in string fires, explosions, etc., which affect the discharge effect
