[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] Embodiment 1:

[0034] Please see attached Figure 1 To Attachment Figure 5As shown, this embodiment 1 provides a powder-free ignition device, which mainly includes an ignition control component 1, an ignition lead 2 and a sleeve 3, wherein the ignition control component 1 is provided with a PCB substrate 10, and an external wire 11 and an ignition chip 12 respectively arranged on the PCB substrate 10, the external wire 11 is used to connect to an external power supply, and the ignition chip 12 can generate heat when the external wire 11 is connected to the external power supply; the ignition lead 2 can be selectively arranged on the PCB substrate 10; the sleeve 3 can be sleeved outside the ignition control component 1, and can press the ignition lead 2 arranged on the PCB substrate 10 tightly against the ignition chip 12, so that when the ignition chip 12 generates heat, the heat can be quickly and fully transferred to the ignition lead 2, thereby achieving an ignition effect with a response time of microseconds and an ignition success rate of 100%.

[0035] The specific structure of the gunpowder-free ignition device described in this embodiment 1 is described in detail below.

[0036] Please continue to refer to the attached Figure 1 To Attachment Figure 5 As shown, in the gunpowder-free ignition device structure provided in the present embodiment 1, the ignition chip 12 may preferably adopt a bridge film type ignition resistor chip or a bridge wire type ignition resistor chip. Regarding the manufacturing method and structure of the bridge film type ignition resistor chip and the bridge wire type ignition resistor chip, it can be adopted as follows: the patch bridge wire type ignition resistor and its manufacturing method provided in Chinese patent CN202311409215.4, so the specific structure of the ignition chip 12 is not described in detail here. With the above-mentioned ignition chip 12 structure, when the ignition device is assembled, the ignition lead 2 can be tightly pressed against the bridge film or bridge wire of the ignition chip 12 by the ferrule 3, so that the heat on the ignition chip 12 is quickly transferred to the ignition lead 2.

[0037] To further illustrate, ① the structural difference between the above-mentioned bridge membrane type ignition resistor chip and the bridge wire type ignition resistor chip is that the bridge membrane is in the shape of a membrane sheet, and the bridge wire is in the shape of a wire; there is no difference in other structures. ② When the ignition chip 12 adopts a bridge membrane type ignition resistor chip, the bridge membrane of the bridge membrane type ignition resistor chip adopts any one of Z shape, II shape, H shape and S shape. And when the ignition chip 12 adopts a bridge wire type ignition resistor chip, the bridge wire of the bridge wire type ignition resistor chip adopts any one of I shape and II shape. The bridge membrane and bridge wire of the above-mentioned shapes have a larger ignition area and can achieve a larger ignition power. Of course, this embodiment is not limited to the above-mentioned bridge membrane and bridge wire shapes, and can be determined according to processing requirements.

[0038] In addition, in the present embodiment 1, the ignition chip 12 is configured as a plurality of chips and fixedly disposed on two opposite sides of the PCB substrate 10; and the plurality of ignition chips 12 can be connected in series, in parallel, or in a combination of series and parallel according to product design requirements. Figure 3 ~Attached Figure 5 It shows a situation where the ignition chips 12 are configured as two and the two ignition chips 12 are connected in series, but the actual production of the product is not limited to the above quantity and electrical connection method. The configuration quantity of the ignition chips 12, the electrical connection method, the resistance value of each ignition chip and other technical parameters are all configured according to the customer's different ignition calorific value requirements for fireworks / fireworks, and this embodiment does not impose any restriction requirements.

[0039] In addition, based on the installation layout design of the ignition chip 12, the installation layout design of the ignition lead 2 in this embodiment 1 is as follows: Figure 3 and attached Figure 4 As shown, the PCB substrate 10 is provided with a through hole 100; after the ignition lead 2 passes through the through hole 100, it is bent relative to the PCB substrate 10, so that the two different sections on the ignition lead 2 are respectively opposite to the ignition chips 12 located on the two opposite sides of the PCB substrate 10; then, the two different sections of the ignition lead 2 can be attached to the two ignition chips 12 (see attached Figure 3 As shown), or, two different sections of the ignition lead 2 may have gaps with the two ignition chips 12 respectively; because when the sleeve 3 is subsequently set, the sleeve 3 can apply a pressing force to the ignition lead 2 so that the two different sections of the ignition lead 2 are tightly pressed / attached to the two ignition chips 12.

[0040] In addition, it should be noted that the ignition fuse 2 can be assembled with the ignition control assembly 1 and the ferrule 3 before the ignition device is shipped out of the factory, or it can be assembled separately and then assembled when the customer uses it; the operation is very flexible.

[0041] Please continue to refer to the attached Figure 1 To Attachment Figure 5 As shown, in the powder-free ignition device structure provided in this embodiment 1, the external wires 11 are configured as two, respectively corresponding to the positive and negative electrodes of the external power supply; and the two external wires 11 are also fixedly connected to one surface or two opposite surfaces of the PCB substrate 10. Figure 2 and attached Figure 3 The figure shows a situation where two external conductors 11 are fixedly connected to two opposite surfaces of the PCB substrate 10 .

[0042] The ferrule 3 includes a hollow casing body 30 made of insulating material and a pressing strip 31 fixedly arranged on the inner wall of the hollow casing body 30 .

[0043] Furthermore, the hollow casing 30 is preferably made of a material with a certain elasticity. The hollow casing 30 and the pressing strip 31 are integrally injection molded, and the materials of the two can be the same or different, for example: the hollow casing 30 and the pressing strip 31 are made of the same material, both of which can be PP or PE plastic material.

[0044] Embodiment 2:

[0045] The second embodiment also provides a non-propellant igniter, and compared with the first embodiment, the non-propellant igniter structure provided in the second embodiment has the following differences: Difference ①, in the non-propellant igniter structure provided in the second embodiment, the layout design of the ignition chip 12 is different from that in the first embodiment. Difference ②, in the non-propellant igniter structure provided in the second embodiment, the layout design of the external wire 11 is different from that in the first embodiment.

Figure 7 ~Attached Fig. 9 It shows the case where the ignition chips 12 are configured as two and the two ignition chips 12 are connected in series, but the actual production of the product is not limited to the above quantity and electrical connection method.

When the clamping sleeve 3 is subsequently set, the clamping sleeve 3 can apply a pressing force to the ignition lead 2, so that the ignition lead 2 is tightly pressed / attached to the two ignition chips 12.

[0048] In addition, similar to the above-mentioned embodiment 1, in this embodiment 2, before the ignition device is shipped out of the factory, the ignition fuse 2 may be assembled with the ignition control assembly 1 and the ferrule 3, or may not be assembled together and then assembled when the customer uses it.

[0049] For the above difference ②, please continue to refer to the attached Figure 7 To Attachment Fig. 9 As shown, in the powder-free ignition device structure provided in the present embodiment 2, the external connecting wires 11 are configured as two and are respectively fixedly connected to one surface of the PCB substrate 10 .
