Technical Field

[0001] This utility model relates to the field of fireworks technology, specifically to an electronically ignited fireworks shell that is wire-free and has built-in anti-static properties. Background Technology

[0002] In scenarios where fireworks shells are required, traditional fireworks shells typically rely on physical fuses (such as detonators) or require on-site connection to the terminals of electronic ignition devices. This presents safety hazards such as the need for close contact with the ignition device during manual wiring, which could lead to accidental contact with high-voltage power or the fuse coming loose. It also requires manually connecting the power cord to the launch device terminal one by one, resulting in a long time consumption and difficulty in meeting the needs of rapid deployment. Furthermore, static electricity accumulation in open-air environments can easily lead to accidental ignition.

[0003] Therefore, a solution is urgently needed to address the problems in existing technologies. Utility Model Content

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1-4 As shown, this application provides a wiring-free electronically ignited firework shell with built-in anti-static properties, comprising: a shell body 11; an electronic ignition wire 12, the ignition head of which is inserted into a pre-drilled hole on the shell body 11; an electrostatic-protective conductive connection structure, which is connected to the positive and negative terminals of the electronic ignition wire 12 and fixes the positive and negative terminals to the outer shell of the shell body 11; the electrostatic-protective conductive connection structure is also used to discharge static electricity from the shell body 11.

[0029] Electrostatic protective conductive connection structures include:

[0030] The conductive structure includes a first conductive sheet 21 and a second conductive sheet 22 that do not contact each other. The first conductive sheet 21 covers the positive terminal head, and the second conductive sheet 22 covers the negative terminal head. The first conductive sheet 21 and the second conductive sheet 22 respectively fix the positive terminal head and the negative terminal head to the outer shell of the projectile 11.

[0031] An anti-static structure is provided, which is electrically connected to the electronic ignition wire 12, and is used to discharge static electricity from the projectile and prevent the electronic ignition wire 12 from being accidentally ignited.

[0032] Specifically, the electronically ignited firework shell consists of a shell body 11, an electronic ignition wire 12, and an electrostatically protected conductive connection structure. The shell body 11 has a pre-drilled hole for inserting the ignition head of the electronic ignition wire 12. When the ignition head of the electronic ignition wire 12 is inserted into the pre-drilled hole on the shell body 11, and a suitable current flows through it, the electronic ignition wire 12 generates high temperature and high pressure, thereby igniting the shell body 11. In this application, the propellant charge of a single shell body 11 is 20g; in other embodiments, the amount of propellant is adjusted according to actual needs.

[0033] The electrostatic-protected conductive connection structure connects to the positive and negative terminals of the electronic ignition wire 12, fixing these two ends to the outer shell of the projectile 11. This not only secures the electrode position and prevents it from loosening or shifting, but also discharges static electricity from the projectile 11, preventing accidental detonation due to static electricity buildup and resulting sparks. The positive and negative terminals of the launching mechanism are electrically connected to the positive and negative terminals of the electronic ignition firework, respectively. By fixing the electrodes of the electronic ignition wire 12 to the outer shell of the projectile 11 through the electrostatic-protected conductive connection structure and forming a static discharge path, the electrode position is ensured to be stable, and accidental detonation caused by static electricity buildup is prevented, thus improving operational safety.

[0034] The conductive structure 20 includes a first conductive sheet 21 and a second conductive sheet 22, which are independent of each other. These cover and fix the positive and negative terminals of the electronic ignition wire 12 to the outer shell of the projectile 11, ensuring both a stable electrode position and establishing a direct path for current conduction. In this application, the first conductive sheet 21 and the second conductive sheet 22 are fixed to the outer shell of the projectile 11 by conductive adhesive. In other embodiments, other fixing methods can also be used to ensure electrical connection between the first conductive sheet 21 and the second conductive sheet 22 and the electronic ignition wire 12. The conductive adhesive ensures a strong bond between the conductive sheet and the end of the electronic ignition wire 12 and the outer shell of the projectile 11, effectively avoiding the loosening problems that may be caused by traditional welding or mechanical fixing, and improving the bonding strength and long-term reliability of the electrode interface.

[0035] The anti-static structure and the electronic ignition wire 12 form an electrical connection circuit, which can discharge the static charge accumulated on the surface of the projectile 11 in real time and avoid accidental detonation caused by high static voltage. When the electronic ignition firework is loaded into the launching mechanism, the positive and negative poles of the launching mechanism directly contact the corresponding first conductive plate 21 and second conductive plate 22, respectively.

[0036] This application presents a wiring-free electronically ignited firework projectile with built-in anti-static properties. The electrostatic-protected conductive connection structure includes a first conductive plate 21 and a second conductive plate 22. The first and second conductive plates 21 and 22 directly fix the positive and negative terminals of the electronic ignition wire 12 to the projectile body 11. The power supply is connected to the terminals via the conductive plates, eliminating the tedious steps of manually connecting each power wire to the launching device terminals in traditional methods. This avoids the risk of close contact with high-voltage power and wire detachment, significantly improving ignition preparation efficiency and eliminating the safety hazard of electric shock for operators. Secondly, it provides protection against... The electrostatic structure is electrically connected to the electronic ignition wire, and static electricity is directly discharged through the conductive sheet, eliminating the risk of accidental ignition caused by static electricity accumulation and enhancing the safety of the fireworks in complex environments. Furthermore, the first conductive sheet 21 and the second conductive sheet 22 respectively fix the positive and negative terminals and conduct current, ensuring a stable and reliable electrical connection, avoiding poor contact problems, and improving the ignition success rate. The method of directly fixing the terminals and conducting current through the conductive sheet replaces the multi-step connection process of traditional terminals and power cords, achieving quick installation in one go and significantly shortening the overall operation time from preparation to ignition.

[0037] This electronically ignited fireworks shell is not only suitable for bird control at airports, but also, due to its rapid deployment capability, can be widely used in large-scale celebrations, festivals, cultural and tourism performances, military exercises, and special scene warnings, as well as other occasions requiring safe and efficient pyrotechnic effects, meeting the needs of multiple fields for rapid response and safe use of fireworks shells.

[0038] In one possible implementation, the positive terminal is connected to the positive lead 121 of the electronic ignition wire 12, and the negative terminal is connected to the negative lead 122 of the electronic ignition wire 12. The anti-static structure includes:

[0039] A normally closed switch 30, wherein the first ends of the positive and negative pins of the normally closed switch 30 are respectively connected to the two ends of the normally closed contact inside the normally closed switch 30; the positive pin is connected to the positive lead 121, and the negative pin is connected to the negative lead 122;

[0040] Before the electronic ignition firework is launched, the normally closed contact is closed; when the electronic ignition firework is launched, the cap is pressed down, the normally closed contact is opened, the positive and negative pins are separated, and the launch mission can be completed after power is applied.

[0041] Specifically, the positive pin of the normally closed switch 30 is directly soldered to the positive lead 121 of the electronic ignition wire 12, and the negative pin is directly soldered to the negative lead 122 of the electronic ignition wire 12. The first ends of the positive and negative pins form a conductive circuit through the internal normally closed contact, putting the positive and negative terminals of the electronic ignition wire 12 in a short-circuit state. The static charge generated on the surface of the projectile 11 due to friction or induction can be directly introduced into the internal discharge channel of the electronic ignition wire 12 through this short-circuit path. When it is necessary to load the electronic ignition firework, the operator presses the cap 31, which pushes the normally closed contact to mechanically separate, cutting off the electrical connection between the positive and negative pins. The electronic ignition firework is then loaded into the launching mechanism, and the positive and negative terminals of the launching mechanism are electrically connected to the positive and negative terminals of the electronic ignition wire 12 through the first conductive plate 21 and the second conductive plate 22, respectively.

[0042] The launching mechanism can be a device with a locking hole that matches the shape of the projectile 11. The locking hole is provided with a positive and a negative terminal of the ignition power supply. When the projectile 11 is placed in the locking hole, the first conductive plate 21 and the second conductive plate 22 on the outer surface of the projectile 11 contact the positive and negative terminals of the ignition power supply in the launching mechanism, respectively, thereby connecting to the power supply.

[0043] In one possible implementation, the antistatic structure includes:

[0044] A fusible structure, wherein the two ends of the fusible structure are respectively connected to the first conductive sheet 21 and the second conductive sheet 22;

[0045] Wherein, the maximum current carrying capacity of the fusible structure is less than the current required for ignition of the electronic ignition wire 12; when the electronic ignition firework is launched, if the applied pulse current is greater than the maximum current carrying capacity of the fusible structure, the fusible structure will automatically melt instantly after being energized, and at the same time, the launching circuit will be connected instantly to complete the launching mission.

[0046] Specifically, the two ends of the fusible structure are connected to the first conductive plate 21 and the second conductive plate 22, respectively. During the electrostatic discharge stage before loading, when electrostatic charge is generated on the surface of the projectile 11 due to friction or induction, the fusible structure has a low fusing current threshold, and its resistance is much smaller than the normal ignition circuit impedance of the electronic ignition wire 12, forming a preferential conduction path. This allows the electrostatic charge to be quickly discharged into the electronic ignition wire 12 through this low-impedance channel, preventing accidental detonation caused by electrostatic accumulation. When a pulse current is applied by the ignition power supply in the launching mechanism, since the maximum current carrying capacity of the fusible structure is less than the current required for the ignition of the electronic ignition wire 12, the instantaneous large current will directly fuse the fusible structure, forcibly cutting off the electrostatic discharge path. This ensures that the pulse current can only form a complete ignition circuit through the electronic ignition wire 12 itself, avoiding the energy diversion problem caused by the parallel connection of the electrostatic discharge path and the ignition circuit, and preventing false triggering caused by leakage of high-voltage pulse through the low-impedance discharge path, thus achieving precise separation of electrostatic protection and ignition control.

[0047] In one possible implementation, the fusible structure includes:

[0048] Fuse 40, the two ends of which are respectively connected to the first conductive sheet 21 and the second conductive sheet 22.

[0049] Specifically, the fuse 40 consists of a molten metal, an insulating shell, and conductive connectors at both ends. The molten metal, serving as both a conductive and fusing component, is made of a low-melting-point alloy material, and its cross-sectional area and length are designed according to a preset fusing current value. The insulating shell encloses the molten metal to provide electrical isolation protection. The conductive connectors at both ends form permanent electrical connections with the first conductive piece 21 and the second conductive piece 22 respectively through welding or crimping. During the electrostatic discharge stage before loading, the fuse 40, due to the low melting point of the molten metal, exhibits an extremely low impedance state, forming an electrostatic discharge channel that prioritizes the normal ignition circuit of the electronic ignition wire 12. This allows the electrostatic charge on the surface of the projectile 11 to be quickly introduced into the internal discharge channel of the electronic ignition wire 12 via this path. When the firing mechanism applies a pulse current, the Joule heat generated by the instantaneous large current in the molten metal rapidly exceeds its melting point threshold, melting and vaporizing within microseconds, forming an irreversible open circuit state. This forcibly cuts off the electrostatic discharge path, ensuring that the pulse current can only form an ignition circuit through the impedance of the electronic ignition wire 12 itself, achieving functional isolation between electrostatic protection and ignition control.

[0050] In this application, the fuse 40 can be a resistance fuse 40. The two ends of the resistance fuse 40 are respectively bonded to the positive and negative conductive copper foils. Before use, the resistance fuse 40 connects the positive and negative terminals, forming a short circuit. The ignition current of the resistance wire is approximately 0.4A, while the electrostatic current is mostly microamps (μA). -6Class A) The resistance wire cannot be melted, thus playing an anti-static role; during normal launch, when the power cord is connected, the current is generally between 1-5A, which will quickly melt the resistance wire, connecting the positive and negative terminals of the projectile 11 and igniting the electronic ignition firework.

[0051] In one possible implementation, the fusible structure includes:

[0052] The third conductive sheet 50 has its two ends connected to the first conductive sheet 21 and the second conductive sheet 22, respectively.

[0053] The area of ​​the third conductive sheet 50 is smaller than the area of ​​the first conductive sheet 21 and smaller than the area of ​​the second conductive sheet 22; the first conductive sheet 21, the second conductive sheet 22 and the third conductive sheet 50 are made of the same material.

[0054] Specifically, the two ends of the third conductive sheet 50 are electrically connected to the first conductive sheet 21 and the second conductive sheet 22 via conductive adhesive. When the first conductive sheet 21, the second conductive sheet 22, and the third conductive sheet 50 are made of the same material, the cross-sectional area of ​​the third conductive sheet 50 is smaller than that of the first and second conductive sheets 21 and 22 connected to it. This results in a higher current density under the same current conditions, leading to increased local resistance and concentrated heat generation. When the transmitting mechanism applies a pulsed current, the third conductive sheet 50 melts rapidly due to the Joule heating effect generated by the instantaneous large current, forming an irreversible open circuit and thus cutting off the electrostatic discharge path. During the electrostatic discharge stage before loading, the electrostatic current flowing through the third conductive sheet 50 is relatively small, and its temperature rise is within a safe range, maintaining stable conductivity and achieving the dual functions of safe electrostatic discharge and high-voltage isolation.

[0055] In this application, the first conductive sheet 21, the second conductive sheet 22, and the third conductive sheet 50 all adopt a sheet-like conductive structure. The sheet-like structure has a large contact area, which can effectively reduce contact resistance, ensure stable transmission of ignition current, and avoid problems such as overheating or insufficient ignition energy caused by excessive resistance. When the conductive sheet is bonded to the electronic ignition wire end and the projectile shell with conductive adhesive, it can more effectively transmit bonding pressure, enhance bonding strength and interface stability, and prevent connection failure due to localized stress concentration. Furthermore, the sheet-like structure facilitates surface contact connection with the positive and negative terminals of the ignition power supply, which significantly improves the reliability of the electrical connection and reduces the risk of poor contact compared to point contact or line contact methods. Moreover, the sheet-like conductive structure has good mechanical strength and stability, capable of withstanding the vibration and impact during fireworks launch, ensuring the continuous reliability of the electrical connection in harsh environments.

[0056] The first conductive sheet 21, the second conductive sheet 22, and the third conductive sheet 50 are selected from one of the following: conductive copper foil, composite copper foil, gold-plated copper foil, copper-clad aluminum foil, conductive polymer, and graphene foil. A variety of conductive materials (such as highly conductive gold-plated copper foil, lightweight copper-clad aluminum foil, or corrosion-resistant conductive polymers) can be flexibly selected to best suit different environmental requirements (such as high temperature, high humidity, or strong corrosion conditions), ensuring excellent conductivity while also meeting durability requirements in specific scenarios. Furthermore, the metal sheet structure coated with conductive adhesive serves the dual functions of conductive connection and mechanical fixation, eliminating the need for additional adhesives or fasteners, simplifying the production process and reducing costs. Simultaneously, the flexible properties of the conductive adhesive can buffer vibration and impact, further improving the firework's vibration resistance during transportation and use, and ensuring stable electrical contact. The conductive adhesive layer can effectively connect the launching mechanism electrodes to the projectile body under slight pressure, significantly shortening on-site assembly time and meeting the needs of rapid deployment. At the same time, the selection of various high-performance conductive materials ensures the high efficiency and stability of the electrical connection, fundamentally solving the problem of ignition failure caused by poor wiring or insecure fixing in traditional electronic ignition fireworks.

[0057] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
