Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a multi-stage toy firework that is designed to create an impact by varying the size and strength of sparks and flame generation.

(Prior art) Originally, toy fireworks can be roughly divided into types that emit flame, powder or sparks, those that rotate, those that fly or are launched, those that make an explosion sound, and those that emit smoke. After all, conventional toy fireworks have only changed the color of the flame, the light emission, the type of sparks, etc. mainly by changing the type of gunpowder.

(Problem that the invention aims to solve) Therefore, although there are various designs in conventional toy fireworks, by changing the type of gunpowder, it is possible to change the size and strength of the flame, sparks, and glow. However, there were drawbacks such as the need to change the type and mixing ratio of the chemicals in the gunpowder.

(Means for Solving the Problems) This invention was made to solve the above-mentioned conventional problems, and has the following configuration.

The multistage toy fireworks of this invention will be described in detail below with reference to the drawings. 1 is a gunpowder cylinder made of plastic or paper filled with gunpowder 4;
The gunpowder cylinder body 1 has a variable construction in which two types of thick powder cylinder parts 2 and fine powder cylinder parts 3 of different thickness are communicated alternately in multiple stages from the top to the bottom. The gunpowder cylinder 1 is integrally fixed to the handle rod 5 by adhesive or the like.

Further, in the embodiment shown in the drawings, the gunpowder barrel 1 has a six-stage configuration with two types of thick powder barrel parts 2 and fine powder barrel parts 3 of different thicknesses, but for example, three types of gunpowder barrels of different thicknesses are used. It is also possible to have a multi-stage structure with explosive cylinder parts. Furthermore, the thickness of the pipe of the gunpowder cylinder portion is changed continuously or discontinuously.

(Function) When the upper end thick powder cartridge part 2 is first ignited by holding the handle part 5 in the hand, the upper end thick powder cartridge part 2
The gunpowder 4 inside burns with a large flame and sparks, and then the flame spreads to the fine powder cylinder 3 in the lower stage, where it burns with small flames and sparks, and so on in a multi-stage downward manner. It is something that burns with change.

(Effects of the invention) As mentioned above, in this invented toy firework, the gunpowder cylinder 1 filled with gunpowder 4 has at least two types of thick powder cylinder part 2 and fine powder cylinder part 3 of different thicknesses. Because the fireworks are made up of multi-stage changes, unlike conventional fireworks where the color of the flame and the type of spark change due to changes in the type of gunpowder, the size of the flame, sparks, and brilliance of a single toy firework can vary. Alternatively, since the scale of intensity can be changed, the power of the fireworks' combustion light is added, and this has the excellent effect of giving toy fireworks an indescribable aesthetic taste and interest.

In addition, this invention has excellent effects as described above even when only one type of gunpowder is used, but when toy fireworks with this configuration are made with various combinations of gunpowder types, both types of gunpowder, that is, gunpowder The combination of the changes due to the type and the changes due to this configuration makes it possible to make toy fireworks with even more remarkable effects.
