[0015] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0016] like Figures 1 to 4 As shown, the present application provides a wiring-free and anti-static electronic ignition firework shell, comprising: a shell body 11; an electronic ignition wire 12, the ignition head of the electronic ignition wire 12 being inserted into a reserved hole on the shell body 11; an electrostatic protection type conductive connection structure, the electrostatic protection type conductive connection structure being connected to the positive terminal and the negative terminal of the electronic ignition wire 12, and the positive terminal and the negative terminal being adhered and fixed to the outer shell of the shell body 11; the electrostatic protection type conductive connection structure is also used to discharge static electricity from the shell body 11; The electrostatic protection conductive connection structure includes: The conductive structure includes a first conductive sheet 21 and a second conductive sheet 22 that are not in contact with each other, wherein the first conductive sheet 21 covers the positive terminal, and the second conductive sheet 22 covers the negative terminal. The first conductive sheet 21 and the second conductive sheet 22 respectively fix the positive terminal and the negative terminal to the outer shell of the elastic body 11; The anti-static structure 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 accidentally igniting.

[0017] Specifically, the electronic ignition fireworks shell consists of a shell body 11, an electronic ignition wire 12, and an electrostatically protected conductive connection structure. The shell body 11 is provided with a reserved hole for inserting the ignition head of the electronic ignition wire 12. The ignition head of the electronic ignition wire 12 is inserted into the reserved hole in the shell body 11. When a suitable current flows through the electronic ignition wire 12, it can generate high temperature and high pressure, thereby igniting the shell body 11. In this application, the charge of a single shell body 11 is 20g. In other embodiments, the charge amount can be adjusted according to actual needs.

[0018] The electrostatically protected conductive connection structure is connected to the positive and negative terminals of the electronic ignition wire 12 and fixed to the outer shell of the projectile 11. This not only serves to fix the electrode position and prevent the electrode from loosening and shifting, but also has the function of discharging static electricity from the projectile 11, preventing the projectile 11 from accidentally detonating due to sparks generated by static electricity accumulation. The positive and negative electrodes of the launching mechanism are respectively electrically connected to the positive and negative terminals of the electronic ignition fireworks shell by contact. The electrostatically protected conductive connection structure fixes the electronic ignition wire 12 electrodes to the outer shell of the projectile 11 and forms an electrostatic discharge path, which can ensure the stable position of the electrodes and avoid accidental detonation caused by static electricity accumulation, thereby improving operational safety.

[0019] The conductive structure 20 includes a first conductive sheet 21 and a second conductive sheet 22 that are independent of each other, which respectively cover and fix the positive terminal and the negative terminal of the electronic fuse 12 to the outer shell of the body 11, ensuring that the electrode position is stable and not loose, and establishing a direct path for current conduction. In the present application, the first conductive sheet 21 and the second conductive sheet 22 fix the positive terminal and the negative terminal of the electronic fuse 12 to the outer shell of the body 11 through conductive glue. In other embodiments, other forms of fixation can also be used to ensure the electrical connection between the first conductive sheet 21 and the second conductive sheet 22 and the electronic fuse 12. The conductive glue can ensure that the conductive sheet is firmly bonded to the end of the electronic fuse 12 and the outer shell of the body 11, effectively avoiding the problem of loose connection that may be caused by traditional welding or mechanical fixation, and improving the electrode interface bonding strength and long-term reliability.

[0020] The anti-static structure and the electronic fuse 12 form an electrical connection loop, which can discharge the static charge accumulated on the surface of the projectile 11 in real time to avoid accidental detonation caused by high static voltage; when the electronic ignition firework shell is loaded into the launching mechanism, the positive and negative poles of the launching mechanism directly contact the corresponding first conductive sheet 21 and second conductive sheet 22 respectively.

[0021] The present invention is a wiring-free and anti-static electronic ignition fireworks shell. The electrostatic protection conductive connection structure is provided with a first conductive sheet 21 and a second conductive sheet 22. The first conductive sheet 21 and the second conductive sheet 22 directly fix the positive terminal and the negative terminal of the electronic fuse 12 on the shell of the shell body 11. The power supply is connected to the terminal through the conductive sheet, eliminating the tedious steps of manually connecting the power cords one by one to the terminals of the launch device in the traditional way, avoiding the risk of manual close contact with the high-voltage power supply and the risk of the lead falling off, greatly improving the efficiency of ignition preparation, and eliminating the safety hazard of electric shock to the operator. Secondly, it can prevent The electrostatic structure is electrically connected to the electronic fuse, and static electricity is directly discharged through the conductive sheet, eliminating the hidden danger of accidental ignition caused by static electricity accumulation, and enhancing the safety of fireworks in complex environments; secondly, the first conductive sheet 21 and the second conductive sheet 22 respectively fix the positive and negative terminals and conduct current, ensuring stable and reliable electrical connection, avoiding poor contact problems, and improving the success rate of ignition; the method of directly fixing the terminals and conducting current through the conductive sheets replaces the multi-step connection process of the traditional terminal block and the power cord, realizing a single quick installation, and significantly shortening the overall operation time from preparation to ignition.

[0022] This electronic ignition fireworks shell is not only suitable for the field of bird repelling at airports, but also can be widely used in large-scale celebrations, festival galas, cultural and tourism performances, military exercises and special scene warnings due to its rapid deployment feature, and other occasions that require safe and efficient pyrotechnic effects, meeting the needs of multiple fields for rapid response and safe use of fireworks shells.

[0023] In one possible embodiment, 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: A normally closed switch 30, wherein the first ends of the positive pin and the negative pin 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; Before the electronic ignition fireworks shell is launched, the normally closed contact is closed; when the electronic ignition fireworks shell is launched, the pressure cap is pressed, the normally closed contact is disconnected, the positive pin and the negative pin are separated, and the launch task can be completed after power is turned on.

[0024] Specifically, the positive pin of the normally closed switch 30 is directly welded to the positive lead 121 of the electronic fuse 12, and the negative pin is directly welded to the negative lead 122 of the electronic fuse 12. The first ends of the positive and negative pins form a conductive loop through internal normally closed contacts, causing the positive and negative poles of the electronic fuse 12 to be in a short-circuit state. The static charge generated by friction or induction on the surface of the projectile 11 can be directly introduced into the internal discharge channel of the electronic fuse 12 through this short-circuit path. When the electronic ignition firework shell needs to be loaded, the operator presses the pressure cap 31, which pushes the normally closed contacts apart mechanically, severing the electrical connection between the positive and negative pins. The electronic ignition firework shell is loaded into the launch mechanism device, and the positive and negative poles of the launch mechanism are electrically connected to the positive and negative terminals of the electronic fuse 12 respectively through the first conductive plate 21 and the second conductive plate 22.

[0025] The launching mechanism can be a device having a card hole that matches the shape of the projectile 11, and the card hole is provided with a positive electrode and a negative electrode of the ignition power supply. When the projectile 11 is set in the card hole, the first conductive sheet 21 and the second conductive sheet 22 on the outer surface of the projectile 11 are respectively in contact with the positive electrode and the negative electrode of the ignition power supply in the launching mechanism, thereby connecting to the power supply.

[0026] In a possible implementation, the anti-static structure includes: a fusible structure, with two ends of the fusible structure connected to the first conductive piece 21 and the second conductive piece 22 respectively; Among them, the maximum carrying current of the fusible structure is less than the current required for ignition of the electronic fuse 12; when the electronic ignition fireworks shell is launched, when the applied pulse current is greater than the maximum carrying current of the fusible structure, the fusible structure will automatically melt instantly after power is turned on, and will instantly connect to the launch circuit to complete the launch task.

[0027] Specifically, the two ends of the fusible structure are connected to the first conductive sheet 21 and the second conductive sheet 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 melting current threshold and its resistance value is much smaller than the normal ignition circuit impedance of the electronic ignition wire 12, forming a priority conduction path, so that the electrostatic charge can be quickly discharged into the electronic ignition wire 12 through this low-impedance channel, thereby avoiding the accumulation of static electricity and causing accidental detonation. When the ignition power supply in the launch mechanism applies a pulse current, since the maximum carrying current 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 melt the fusible structure, forcibly cutting off the electrostatic discharge path, ensuring 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 the high-voltage pulse from leaking through the low-impedance discharge path and causing false triggering, thereby achieving precise separation of electrostatic protection and ignition control.

[0028] In one possible implementation, the fusible structure includes: The fuse 40 has two ends connected to the first conductive piece 21 and the second conductive piece 22 respectively.

[0029] Specifically, fuse 40 consists of a molten metal, an insulating tube shell, and two conductive connectors at both ends. The molten metal, serving as both the conductive and fusing component, is made of a low-melting-point alloy material, with its cross-sectional area and length designed according to a preset fuse current value. The insulating tube shell encases the molten metal, providing electrical isolation protection. The two conductive connectors are welded or crimped to form permanent electrical connections with the first conductive plate 21 and the second conductive plate 22, respectively. During the pre-loading electrostatic discharge phase, fuse 40, due to its low melting point, exhibits an extremely low impedance, forming an electrostatic discharge path that takes precedence over the normal ignition circuit of the electronic fuse 12. This allows the static charge on the surface of the projectile 11 to be rapidly transferred through this path into the internal discharge path of the electronic fuse 12. When the firing mechanism applies a pulse current, the Joule heat generated by the instantaneous high current in the molten metal rapidly exceeds its melting point threshold, causing it to melt and vaporize within microseconds, forming an irreversible open circuit. This forcibly cuts off the electrostatic discharge path, ensuring that the pulse current can only form an ignition circuit through the inherent impedance of the electronic fuse 12, thus achieving functional isolation between electrostatic protection and ignition control.

[0030] In this application, the fuse 40 can be a resistor fuse 40. The two ends of the resistor fuse 40 are respectively bonded to the positive and negative conductive copper foils. Before the electronic ignition fireworks are used, the resistor fuse 40 is connected to the positive and negative poles to form a short circuit. The ignition current of the resistor wire is about 0.4A, while the electrostatic current is mostly microamperes (μA, 10 -6 A) level, the resistance wire cannot be melted, thereby 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, connect the positive and negative poles of the projectile body 11, and ignite the electronic ignition fireworks shell.

[0031] In one possible implementation, the fusible structure includes: A third conductive sheet 50 , two ends of which are connected to the first conductive sheet 21 and the second conductive sheet 22 respectively; The area of ​​the third conductive sheet 50 is smaller than that of the first conductive sheet 21 and smaller than that 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.

[0032] 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 through conductive glue or respectively. When the first conductive sheet 21, the second conductive sheet 22 and the third conductive sheet 50 are made of the same material, since the cross-sectional area of ​​the third conductive sheet 50 is smaller than that of the first conductive sheet 21 and the second conductive sheet 22 connected to it, it has a higher current density under the same current conditions, resulting in an increase in local resistance and concentrated heat generation; when the transmitting mechanism applies a pulse current, the third conductive sheet 50 cannot withstand the Joule heating effect generated by the instantaneous large current and quickly melts, forming an irreversible open circuit state, thereby cutting off the electrostatic discharge path. During the electrostatic discharge stage before loading, the electrostatic current flowing through the third conductive sheet 50 is small, and its temperature rise is within a safe range, which can maintain stable conductive performance and achieve the dual functions of electrostatic safety discharge and high-voltage isolation.

[0033] In the present 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 the contact resistance, ensure the stable transmission of the ignition current, and avoid the problem of heat generation or insufficient ignition energy caused by excessive resistance. When the conductive sheet is fixed to the end of the electronic fuse and the shell of the projectile by conductive adhesive, it can more effectively transmit the fitting pressure, enhance the bonding strength and interface stability, and prevent connection failure caused by local stress concentration. In addition, the sheet-like structure is convenient for forming a surface contact connection with the positive and negative terminals of the ignition power supply, which can significantly improve the reliability of the electrical connection and reduce the risk of poor contact compared to point contact or line contact. Moreover, the sheet-like conductive structure has good mechanical strength and stability, and can withstand the vibration and impact during the launch of fireworks, ensuring the continued reliability of the electrical connection in harsh environments.

[0034] The first conductive sheet 21, second conductive sheet 22, and third conductive sheet 50 are each selected from one of 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 polymer) allow for flexible selection of the optimal material based on different environmental requirements (e.g., high temperature, high humidity, or severe 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. The flexible nature of the conductive adhesive also buffers vibration and shock, further improving the shell's resistance to shock during transportation and use, and ensuring electrical contact stability. The conductive adhesive layer can effectively connect the electrodes of the launching mechanism and 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 a variety of high-performance conductive materials ensures efficient and stable electrical connections, fundamentally solving the problem of ignition failure caused by poor wiring or loose fixation in traditional electronic ignition fireworks.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
