Description

Technical Field

[0001] The utility model relates to the field of fireworks setting off devices, in particular to a fireworks setting off device which increases the fun. Background Art

[0002] The production and use of fireworks in China has a long history. The scope of use involves all aspects of people's lives. They are widely used in the New Year, festivals, festive occasions, and celebrations. It is a traditional and beautiful way of expressing emotions. Fireworks are made of pyrotechnic powder as the main raw material. After ignition, they burn or explode to produce light, sound, color, shape, smoke and other effects. They are used for viewing and are flammable, explosive and dangerous items.

[0003] Most of the fireworks currently sold on the market are set off upwards, with a small number of spray flowers. Due to structural limitations, the area of ​​the fireworks sprayed out when set off is not large, and the form is single. In addition, the existing rotatable fireworks are also affected by the structure and often rotate unsmoothly when set off, and are easy to get stuck, which makes them poor in viewing and interest.

[0004] Later, a combination firework with a rotating effect appeared on the market, comprising a firework tube and a base located below the firework tube, wherein a vertical nozzle is provided at the middle end of the firework tube, a plurality of functional nozzles are provided on the outer side of the vertical nozzle, and a plurality of horizontal nozzles are provided on the outer side wall of the firework tube; a mounting seat is connected to the bottom end of the firework tube, and the mounting seat and the base are rotated by a rotating mechanism, wherein the rotating mechanism comprises a support block connected to a groove opened at the top of the base and a plurality of rolling balls rollingly connected to a rolling groove formed on the top surface of the support block, wherein the support block is rollingly connected to the mounting seat through a plurality of rolling balls, and a clamping piece is connected to the top end of the support block, and the clamping end of the clamping piece passes through the bottom of the mounting seat and extends into the clamping groove opened inside the mounting seat, so that the firework tube rotates smoothly on the base, thereby improving the overall safety; however, this combination firework with a rotating effect has the following defects:

[0005] For example, the fireworks are presented with dynamic and novel fireworks entertainment effects by rotating the mounting seat and the base through a rotating mechanism. This method of increasing the fun of fireworks is relatively simple, which limits the entertainment value of the product. In addition, the rotating mechanism uses the rotation of multiple rolling balls and multiple round balls, which makes the way the firework tube is ignited and rotated too complicated, and it has more overall parts, the assembly process is cumbersome, and the production cost is high.

[0006] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
