[0040] A spray flower new type spray flower combination firework is usually provided with a plurality of spray flower cartridges. At present, this type of spray flower new type spray flower combination firework is mostly composed of a plurality of spray flower cartridges glued together. An important technical factor of this type of firework is the control of the firing time, that is, the ignition fuses of each spray flower cartridge are connected by a fire transfer fuse, and the interval of the ignition time of each spray flower cartridge is set by the length and / or burning speed of the fire transfer fuse to meet the predetermined firing rhythm, so as to achieve the designed firing effect.

[0041] The novel spray flower combination fireworks provided in the present application specifically include a shell 1, a spray flower cartridge 2 and a ignition fuse 3. Among them, an installation space 11 is provided inside the shell 1, and at least one lead wire groove is provided on the outer side of the shell 1. There are multiple spray flower cartridges 2, and multiple spray flower cartridges 2 are arranged in the installation space 11. The ignition fuse 21 of the spray flower cartridge 2 passes through the shell 1 and extends into the lead wire groove. The ignition fuse 3 is arranged in the lead wire groove and abuts against multiple ignition fuses 21.

[0042] The new spray flower combination fireworks described in the utility model include a shell 1, a spray flower cartridge 2 and a fire transfer fuse 3. A lead groove is provided on the outer side of the shell 1, and the lead groove can accommodate the ignition fuse 21 of the spray flower cartridge 2, so that the fire transfer fuse 3 and the ignition fuse 21 are in contact, which helps to reduce the occurrence of phenomena such as cross distribution of the fuses and damage to the fuse surface, and can standardize the arrangement of the fire transfer fuse 3 to improve the stability of product quality. At the same time, it also helps to simplify the connection steps of the fire transfer fuse 3 and the ignition fuse 21, thereby effectively improving the installation efficiency of the new spray flower combination fireworks and the convenience of its production.

[0043] Specifically, if Figure 1As shown, the novel spray flower combination fireworks at least include a shell 1, a spray flower cartridge 2 and a ignition fuse 3. The shell 1 includes a side plate and a bottom plate. The side plate is a cylindrical structure as a whole, and the two ends of the cylindrical structure are opened. The bottom plate is set at the bottom of the cylindrical structure and forms a receiving cavity with a top opening with the side plate. At this time, the receiving cavity is the above-mentioned installation space 11, which is used to accommodate the above-mentioned spray flower cartridge 2. In addition, the shell 1 can also be set as other structures to be able to place the spray flower cartridge 2.

[0044] In some embodiments of the present invention, the housing 1 is configured as a cylinder or a regular prism. In this embodiment, the housing 1 is configured as a triangular prism. Figure 2-Figure 4 As shown, the cylindrical structure is formed by three side panels. In the horizontal direction, avoidance structures are provided on both sides of any side panel so that two adjacent side panels can effectively fit together to form a triangular prism when spliced. In other embodiments, the shell 1 can be in the shape of a cylinder, a regular prism (such as a cube, a cuboid, a hexagonal prism or an octagonal prism), etc. Preferably, the shell 1 can be formed in one step by an injection mold, or the plate body can be processed first, and then several plate bodies can be assembled and combined to form a mold. Among them, the molding process is more convenient.

[0045] It should be understood that at least one lead groove is provided on the outer side of the shell 1. The lead groove is used to place the ignition fuse 3. In the present embodiment, the ignition fuse 3 is a whole lead distributed in the entire lead groove. Specifically, the lead groove is arranged on the outer side of the shell 1 in an up and down reciprocating distribution manner, and the position where the lead groove turns adopts an arc structure. Such a setting helps to further avoid the occurrence of small-angle folding and crossing phenomena, and the intervals between the leads are clear and stable, which helps to avoid the risk of ignition and even sympathetic explosion, and helps to achieve a standardized distribution of the leads, so that they have a thread to follow during processing, will not cross, and the process standards are convenient.

[0046] Here, it should be noted that, in addition to the up-and-down distribution in the above example, the lead slots may also be distributed in left-and-right, oblique, spiral, or wavy distributions, etc., without affecting the purpose of the invention.

[0047] It should be further understood that the number of lead grooves is set to two, the lengths of the two lead grooves are different, and the two lead grooves are partially connected. This arrangement is convenient for using different lead grooves as needed, thereby changing the length of the ignition fuse 3, adjusting and setting the interval of the ignition time of each spray cartridge 2, and helping to improve the application range of the shell 1 and its mold. In other embodiments, the above-mentioned exemplary method may not be used to form lead grooves of different lengths. Of course, other methods may also be used to construct lead grooves of different lengths.

[0048] Specifically, for ease of description, the above two lead grooves are referred to as the first lead groove 41 and the second lead groove 42. Among them, the length of the first lead groove 41 is different from the length of the second lead groove 42. Specifically, the first lead groove 41 and the second lead groove 42 have the same structure, and the first lead groove 41 is used as an example for description below. The first lead groove 41 includes a straight left channel and a straight right channel, and the straight left channel and the straight right channel are connected together by a connecting channel. The difference between the first lead groove 41 and the second lead groove 42 is that the lengths of the straight left channel and the straight right channel are different. And preferably, the straight left channel and the straight right channel of the second lead groove 42 are parts of the straight left channel and the straight right channel of the first lead groove 41. At this time, a plurality of lead holes 12 connected to the mounting cavity are opened on the top of the shell 1. By providing the lead hole 12, the ignition lead 21 can extend out of the housing 1 through the lead hole 12 and connect with the fire transfer lead 3, which helps to improve the positioning effect of the ignition lead 21 and make its position have a certain stability. Preferably, the lead hole 12 is connected to the lead groove. Such a setting can make the ignition lead 21 and the fire transfer lead 3 connected in the lead groove, which helps to improve the reliability of the connection between the fire transfer lead 3 and the ignition lead 21, and can achieve standardized distribution, so that there is a vein to follow during processing, and there will be no crossover, and the process standard is convenient, which can effectively improve the stability of product quality and the convenience of production.

[0049] In some other embodiments of the present invention, a fire transmission channel is further provided on the outer side of the housing 1, and the fire transmission channel is used to connect the lead wire hole 12 and the lead wire groove. The provision of the fire transmission channel can effectively adjust the connection effect between the ignition fuse 21 and the fire transmission fuse 3, thereby further ensuring the reliability of the connection between the fire transmission fuse 3 and the ignition fuse 21.
