Description

Technical Field

[0001] The utility model relates to the technical field of ignition devices, in particular to a firework igniter. Background Art

[0002] Existing firework igniters are all based on electric ignition heads. A heating element tungsten wire is connected between the two wires of the electric ignition head, and ignition powder is coated on the tungsten wire. However, the diameter of the tungsten wire used in general fireworks ignition is relatively small. Therefore, when producing igniters, the tungsten wire is prone to bending or breaking. If the bending point is misaligned with the position of the ignition powder, the bending point will be melted first during ignition due to the high resistance, which will cause the igniter to fail to detonate the fireworks normally. This has a great impact on the discharge of fireworks, especially in large-scale fireworks performances. Utility Model Content

[0003] In view of the above problems existing in the prior art, the firework igniter provided by the utility model is used to overcome the above defects in the prior art.

[0004] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is as follows:

[0005] A fireworks igniter comprises a substrate, wherein an ignition chip and a through hole are arranged at one end of the front side of the substrate, a diode is arranged on the ignition chip, a first circuit is printed on the front side of the substrate, and a second circuit is printed on the back side of the substrate, one end of the first circuit is connected to one end of the diode, and the other end is connected to a first wire, one end of the second circuit is connected to the second wire, and the other end is connected to the other end of the diode via the through hole and the front side of the substrate, and the diode is wrapped with ignition powder.

[0006] In one embodiment, two ends of the diode are welded to the first circuit and the second circuit respectively, and the first wire is welded to the first circuit and the second wire is welded to the second circuit respectively.

[0007] In one embodiment, the substrate is a rectangular plate-shaped structure.

[0008] In one embodiment, a protective cover is sleeved on the outside of the substrate, and the protective cover is opened at both ends. The opening diameter of the end of the protective cover away from the first wire and the second wire is larger than the width of the substrate, and the opening diameter of the end of the protective cover close to the first wire and the second wire is smaller than the width of the substrate, and the protective cover is sleeved on the outside of the first wire and the second wire.

[0009] Compared with the prior art, the fireworks igniter provided by the utility model abandons the traditional ignition method of using a resistance wire to ignite the ignition powder, and innovatively uses a diode to produce the fireworks igniter, which uses the diode to generate heat by energizing to ignite the ignition powder to ignite the fireworks. Because the resistance value of the diode itself is more stable and uniform when it leaves the factory, and at the same time, when the fireworks igniter is produced, it will not cause uneven resistance or short circuit problems due to bending. Therefore, it can greatly improve the stability and success rate of the fireworks ignition operation, and is particularly suitable for large-scale fireworks performances that require multiple igniters to work together.

[0017] like Figure 1 and 2 As shown, for the convenience of description, the directions of "up", "down", "left", "right", "front" and "rear" in the present invention are based on the attached Figure 1 The directions shown shall prevail;

[0018] A firework igniter comprises a substrate 1 of a rectangular plate structure, an ignition chip 2 and a through hole 3 are arranged at the upper end of the front side of the substrate 1, a diode is arranged on the ignition chip 2, a first circuit 4 is printed on the front side of the substrate 1, and a second circuit 5 is printed on the back side, an upper end of the first circuit 4 is connected to one end of the diode, and the other end is connected to a first wire 6, one end of the second circuit 5 is connected to a second wire 7, and the other end is connected to the other end of the diode via the through hole 3 and the front side of the substrate 1, and an ignition powder 8 is wrapped around the outside of the diode.

[0019] In this embodiment, two ends of the diode are welded to the first circuit 4 and the second circuit 5 respectively, and the first wire 6 is welded to the first circuit 4 and the second wire 7 is welded to the second circuit 5 respectively.

[0020] Through the above technical solutions, it can be known that the fireworks igniter provided by the utility model uses the principle of diode heating when it is energized to ignite fireworks. Because diodes are mature products, the error of the resistance value of each diode is small when it is produced. At the same time, when diodes are used to assemble and produce fireworks igniters, they are less affected by the outside world and will not be easily bent or broken like resistance wires. Therefore, each fireworks igniter produced using diodes has a very high and stable success rate in igniting fireworks, and is therefore deeply loved by consumers, especially in large-scale fireworks performances, because large-scale fireworks performances require a large number of fireworks, and each firework needs to be ignited at a precise time point, so there is an even greater need for a fireworks igniter with a high and stable ignition success rate.

[0021] In this embodiment, a protective cover is mounted on the outside of the substrate 1. The protective cover is opened at both ends. The opening diameter of the upper end of the protective cover is larger than the width of the substrate 1, and the opening diameter of the lower end of the protective cover is smaller than the width of the substrate 1. The protective cover is mounted on the outside of the first wire 6 and the second wire 7. By providing the protective cover, the substrate 1, the ignition chip 2, the first wire 6, the second wire 7 and the ignition powder 8 are protected to avoid damage caused by foreign objects from the outside, which may lead to a low success rate of fireworks ignition.

[0022] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0023] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
