The description in this part is only exemplary and explanatory, and should not be used to limit the protection scope of this utility model in any way. Example

[0018] like Figs. 1-3 As shown, the leadless colored smoke inner cylinder includes an inner cylinder 4; the inner cylinder 4 is provided with a sealing 7, a smoke-generating agent 6 and a sealing layer 5 in sequence along the axial direction; the sealing layer 5 is provided with at least one ignition hole 51, and the inner cylinder 4 is provided with a smoke-generating hole on its side wall.

[0019] Specifically, the inner tube 4 is a paper tube, a blocking layer 5 is bonded to the bottom of the inner tube 4, and the blocking layer 5 is also made of paper in this embodiment. The blocking layer 5 and the inner tube 4 can be bonded by gluing. A plurality of ignition holes 51 are arranged in the middle of the blocking layer 5. In this embodiment, the number of the ignition holes 51 is five, which are arranged in a layout of one in the middle and four around the one, so that the positions of the ignition holes 51 are matched with the positions of the ignition holes on the upper paper sheet 2. When the firework is ignited, the ignition wire on the outer tube 1 is ignited to ignite the launching powder 8 in the outer tube 1. The launching powder 8 burns fiercely and generates a large amount of gas, which in turn sends the upper paper sheet 2, the inner tube 4 and the lower paper sheet 3 into the air. When the launching powder 8 is ignited, the flame passes through the ignition hole 51 to ignite the smoke generating powder 6 in the inner tube 4. The smoke generated by the ignition of the smoke generating powder 6 is discharged from the smoke generating hole 52 to form a smoke effect.

[0020] In another embodiment, the inner tube 4 and the blocking layer 5 can be made of a molded material, which is similar to the material used in existing molded fireworks and formed into a whole by a hot pressing process.

[0021] As a preferred mode of the above embodiment, the material of the blocking layer 5 is the same as that of the inner tube 4, the blocking layer 5 and the inner tube 4 are integrated, the number of the ignition holes 51 on the blocking layer 5 is five, and the ignition holes 51 are uniformly distributed on the blocking layer 5.
