Technical Field
[0001] The utility model relates to an improved structure of a cracker firework, belonging to the technical field of toy fireworks manufacturing. Background Art
[0002] In the prior art, the firecracker fireworks in the toy fireworks are also called Christmas fireworks. They are composed of a cylinder with effect paper parts and a small-diameter tube with built-in firecrackers. The upper and lower parts of the cylinder with the effect parts are closed with a piece of cardboard respectively, and the short-section firecracker tube connected to the bottom of the effect cylinder contains gunpowder and a thin pull rope / line. When igniting, one hand clamps the upper effect cylinder or the short-section small-diameter tube with firecrackers, and the other hand pulls the firecracker pull rope to cause deflagration. The gas energy generated after the deflagration pushes the upper and lower cover plates with the effect parts in the middle upward to rush out of the cylinder mouth for firing. There are many shortcomings in this structure of firecrackers. The main defects are: first, the explosion point of the firecracker in the prior art is in the small diameter tube at the bottom of the large diameter cylinder, which is easy to burn the hands of the operator; second, the upper and lower covers of the effect parts do not have a boss edge to stop the top positioning, which is easy to fall off and affect the firing; third, the cylinder explosion space is small, the launch energy is insufficient, the distance after the launch outlet of the effect paper part is close, the firing effect is not good, and the needs of the fireworks market are affected. The last point is that the process without medicine and the process with medicine cannot be processed and produced separately, which increases the safety hazard. For this reason, it is extremely necessary to innovate and develop a new type of firecracker fireworks structure with a large capacity and a firecracker explosion point that is not at the bottom.
