[0005] As a preferred technical solution of this utility model, kraft paper is laid between the firework tubes in the same row, and the firework tubes are fixed to the side of the kraft paper by adhesive.

[0006] As a preferred technical solution of this utility model, the combined fireworks are bound and fixed together with tape.

[0007] As a preferred embodiment of this invention, the combined fireworks are provided with a cardboard box for protection.

[0008] As a preferred technical solution of this utility model, the overall opening angle of the combined fireworks is 45°.

[0009] As a preferred embodiment of this utility model, the outer diameter of the firework tube is 38mm, the inner diameter is 30mm, and the height of the firework tube is 225mm.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model illustrates a combination firework with a double-layer composite effect, which is filled with two different types of firework shells. When ignited, the two types of firework shells are ignited alternately, and this method allows the ignition effects of the two types of firework shells to be combined, making it more visually appealing than traditional fireworks. At the same time, it is safer than the traditional method of igniting two types of fireworks simultaneously. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 This utility model provides a technical solution: a combination firework with a double-layer composite effect, including a combination firework whole, which is composed of several firework tubes 1. The outer diameter of the firework tube 1 is 38mm, the inner diameter is 30mm, and the height of the firework tube 1 is 225mm. The combination firework whole is designed in the shape of an open screen, with an opening angle of 45°. The firework tubes 1 are arranged in ten rows, namely five rows on the left and five rows on the right, which are symmetrically arranged. Each row of firework tubes 1 is equipped with thirteen firework tubes, that is, the combination firework can be set off in a total of 130 shots.

[0016] The combination fireworks system contains two types of firework shells. The same firework shells are filled in the same row of firework tubes 1, while the firework shells in adjacent rows of firework tubes 1 are different. Preferably, the firework shells in the first, third, fifth, seventh, and ninth rows are the same, with red heads and silver chrysanthemum tails, while the firework shells in the second, fourth, sixth, eighth, and tenth rows are green heads and silver chrysanthemum tails. When set off, the two types of firework shells combine to create a combined effect, enhancing the visual appeal.

[0017] A row of fuses is provided between two adjacent firework tubes 1 in the same row. Preferably, the row of fuses is 8cm long and the ignition time is 1-2 seconds. A surrounding fuse is provided between two adjacent rows of firework tubes 1. Preferably, the surrounding fuse is 10cm long and the ignition time is 50-55 seconds. A main fuse 4 is provided in the middle of the left side of the combined firework. The main fuse 4 is connected to the surrounding fuse. Preferably, the main fuse 4 is 10cm long and the ignition time is 75-80 seconds. The surrounding fuse is ignited by igniting the main fuse 4, and then the surrounding fuse ignites the row of fuses to set off the combined firework. The installation and setting of the main fuse 4, surrounding fuse, and row of fuses can adopt existing technology.

[0018] Kraft paper 3 is laid between the firework tubes 1 in the same row. The firework tubes 1 are fixed to the side of the kraft paper 3 with adhesive. The combined fireworks are bound and fixed with tape, or the combined fireworks can be fixed with wire. Preferably, the firework tubes 1 in the combined fireworks are wrapped with kraft paper 3 in double rows and can be fixed with wire. The combined fireworks are provided with a cardboard box 2 for protection. The cardboard box 2 has the effects of moisture protection and decoration.

[0019] This combination of fireworks is filled with two different types of fireworks shells. When ignited, the two types of fireworks shells are fired alternately, and this method allows the firing effects of the two types of fireworks shells to be combined, making it more visually appealing than traditional fireworks. At the same time, it is safer than igniting two fireworks shells at the same time.
