[0017] Figure 3 The circuit principle of a lead electronic ignition device proposed by the utility model Figure 3 ; DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0019] Example 1

[0020] refer to Figure 1 and Figure 3 In this embodiment, a lead electronic ignition device powered by a button battery is proposed. The device includes a control module and an ignition module. The control module is electrically connected to the ignition module, the ignition module is controlled by the control module, and the ignition module is powered by a button battery.

[0021] The control module is the core part of the entire electronic ignition device, and is mainly responsible for managing the timing and process of ignition. The control module in this embodiment controls the operation of the ignition module after the preset conditions are met.

[0022] The ignition module is the part that actually completes the ignition task. It is mainly responsible for converting electrical energy into heat energy to ignite the fuse.

[0023] In this embodiment, the ignition module is powered by a button battery, which includes components such as a switch tube, a heating wire, and a super capacitor.

[0024] After receiving the signal from the control module, the ignition module will release the energy stored in the supercapacitor according to the instructions, convert the energy into heat energy through the heating wire, and ignite the fuse.

[0025] The function of the ignition module is similar to that of an "actuator" in electronic equipment, which is responsible for executing instructions issued by the control module and completing specific tasks.

[0026] The structures of the control module and the ignition module are specifically described in this embodiment, wherein the control module includes a control chip U1 of model WSF001L14, wherein pin 2 of the control chip U1 is connected to one end of a switch K1, and the other end of the switch K1 is grounded. K1 in this embodiment can realize the switching function of the circuit. When K1 is closed, the control chip U1 can sense this state change, thereby starting the ignition device; when K1 is disconnected, the control chip U1 can also sense it and stop the operation of the ignition device.

[0027] According to different application scenarios, K1 can also be used as a starting trigger. When the user operates K1 to close it, the control chip U1 receives the signal, performs corresponding processing according to the preset logic, and starts the ignition process of the ignition device.

[0028] K1 can also be used as a safety protection mechanism. Switch K1 is closed only when ignition is required to prevent accidental ignition or misoperation. When ignition is not required, disconnecting K1 can effectively avoid unnecessary safety risks.

[0029] Pin 3 of the control chip U1 is connected to the anode of the light-emitting diode D1, and the cathode of the light-emitting diode D1 is grounded. The light-emitting diode D1 in this embodiment is used as an indicator light to display the working status of the electronic ignition device. When the circuit is powered on and the control chip U1 is working, the light-emitting diode D1 will be lit, indicating that the device is working; when the circuit is disconnected or the control chip U1 stops working, the light-emitting diode D1 will go out, indicating that the device stops working.

[0030] Depending on different application scenarios, the light-emitting diode D1 can also be used to indicate faults or abnormal conditions. When the control chip U1 detects a fault or abnormal condition in the circuit, it can indicate to the user by controlling the on and off state of the light-emitting diode D1, prompting the user that there is a problem that needs to be handled.

[0031] The light emitting diode D1 can also be used to provide other information to the user, such as the ignition device is ready or the ignition is successful, etc. By controlling the on and off mode of the light emitting diode D1, various prompt information can be conveyed to the user.

[0032] The 5th pin of the control chip U1 is respectively connected to one end of the resistor R2 and the signal input end of the ignition module. The resistor R2 limits the current flowing through the 5th pin of the control chip U1 to play a protective role. Usually, the pins of the microcontroller are sensitive to external signals. By connecting a resistor of appropriate size, the flow of current can be limited to protect the control chip.

[0033] In other application scenarios, resistor R2 can also be used to prevent excessive voltage from impacting the input pin of the control chip, thereby playing a role in voltage stabilization.

[0034] The ignition module includes a switch tube Q1, a heating wire R1, a super capacitor C1 and a button battery. Pin 1 of the switch tube Q1 is connected to pin 5 of the control chip U1, pin 2 of the switch tube Q1 is respectively connected to the negative electrode of the super capacitor C1 and the negative electrode of the button battery, pin 3 of the switch tube Q1 is connected to one end of the heating wire R1, and the other end of the heating wire R1 is respectively connected to a 3V+ voltage, a positive electrode of the super capacitor C1, and a positive electrode of the button battery.

[0035] In this embodiment, the switch tube Q1 includes but is not limited to a triode, and the control chip U1 controls the conduction and cutoff of the switch tube Q1 through its 5-pin connection base, thereby controlling the ignition signal of the ignition device. When the control chip U1 generates a trigger signal, an appropriate voltage is applied to the switch tube Q1 through the 5-pin to make it conduct, thereby forming a circuit path, and the ignition device starts to work. When the control chip U1 does not generate a trigger signal, an appropriate voltage is applied to the switch tube Q1 through the 5-pin to make it cut off, thereby cutting off the circuit and stopping the work of the ignition device. The 2 pins of the switch tube Q1 are respectively connected to the negative electrode of the supercapacitor C1 and the negative electrode of the button battery to provide power supply. When the switch tube Q1 is turned on, a path is formed between the supercapacitor C1 and the button battery, and the current can flow through the ignition device, and the ignition device starts to work. When the switch tube Q1 is turned off, the connection between the supercapacitor and the battery is cut off, thereby stopping the work of the ignition device. When the ignition device starts to work, the button battery charges the supercapacitor C1. Since the output power of the button battery is small, it is not enough to directly ignite the heating wire, so the supercapacitor charging is increased. In this process, the control circuit will transfer the power of the button battery to the supercapacitor, gradually filling the supercapacitor. When the fuse needs to be ignited, the control circuit will control the supercapacitor to conduct instantly, so that the power stored in the supercapacitor is quickly released. This creates a short but high-power current pulse. This pulse current will pass through the heating wire, causing the heating wire to heat up quickly. Since the heating wire is a high-resistance conductor, when a high-power current passes through it, the Joule heating effect will occur, causing the temperature of the heating wire to rise rapidly. Once the heating wire reaches a high enough temperature, it can ignite the nearby fuse, thereby triggering the desired ignition process.

[0036] It should be clarified that in the ignition device that ignites the fuse in this way, a plastic diaphragm is provided between the button batteries. When the plastic diaphragm is removed, the button batteries are energized, and the control chip controls the heating wire to heat up according to the set timing time. The control chip used in this embodiment can realize the function of delayed ignition through programming, because WSF001L14 is a general-purpose single-chip microcomputer with rich peripherals and flexible programming functions, so various timer functions can be realized through programming, including delayed ignition.

[0041] The ignition module includes a switch tube Q1, a heating wire R1, a super capacitor C1 and a button battery. Pin 1 of the switch tube Q1 is connected to pin 5 of the control chip U1, pin 2 of the switch tube Q1 is respectively connected to the negative electrode of the super capacitor C1 and the negative electrode of the button battery, pin 3 of the switch tube Q1 is connected to one end of the heating wire R1, and the other end of the heating wire R1 is respectively connected to a 3V+ voltage, a positive electrode of the super capacitor C1, and a positive electrode of the button battery.

[0042] Pins 4 and 6 of the control chip U1 are connected to a wireless transceiver module, which can receive radio frequency signals from external devices or sensors and convert them into digital signals for processing or other operations by the control chip U1. Specifically, the wireless transceiver module includes a communication chip U2 of model LT8960L, wherein pin 1 of the communication chip U2 is connected to pin 1 of the crystal oscillator Y1, and pin 3 of the crystal oscillator Y1 is connected to pin 8 of the communication chip U2. In the communication chip U2, the crystal oscillator Y1 is used as the main clock source to control the timing of the entire communication system and provide a basic clock frequency for the communication chip U2 for synchronizing various operations, including data transmission and modulation and demodulation. Pin 2 of the communication chip U2 is connected to one end of the resistor R4, and the other end of the resistor R4 is connected to the RF ground, wherein the resistor R4 is used to match the impedance of the signal, and pin 3 of the communication chip U2 is connected to the RF end of the antenna and one end of the capacitor C3, and the other end of the capacitor C3 is connected to the RF ground, and the capacitor C3 is used to block the DC signal, transmit the RF signal, improve the stability of the system, and prevent the DC signal from interfering with the transmission of the RF signal. Pin 6 of the communication chip U2 is connected to pin 4 of the control chip U2. The clock signal is used to synchronize the data transmission, ensuring the synchronization and correct transmission of the data. The control chip U2 can use the clock signal to accurately control the sampling and processing timing of the data. Pin 6 of the communication chip U2 is connected to pin 6 of the control chip U2. The control chip U2 receives or sends data by reading or writing data signals.

[0043] Based on this embodiment, a practical application scenario is proposed:

[0044] Wirelessly controlled electronic igniters are built into fireworks to ensure their safety and stability. Users start terminal devices including but not limited to mobile phones and tablets, open the corresponding control applet, and use the camera of the terminal device to scan the QR code on the outer packaging of the fireworks.

[0045] The terminal device identifies and parses the information in the QR code, which contains the unique ID of the electronic igniter. Based on the parsed QR code information, the control applet matches the wireless function on the terminal device and establishes a wireless connection with the electronic igniter. Once the wireless connection is established, the terminal device can send control instructions to the electronic igniter, such as starting ignition, setting delay, etc. After receiving the instructions, the electronic ignition device implements the corresponding operations through the internal control chip and ignition module, such as turning on the switch and igniting the fuse.

[0046] The control applet needs to use the positioning function of the terminal device, such as GPS, base station positioning, Wi-Fi positioning, etc., to obtain the geographic coordinate information of the current location, and convert the obtained geographic coordinate information into a specific address description or administrative division information by calling the API of the geographic information service (such as Google Maps, Baidu Maps, etc.). A database of legal discharge addresses is maintained on the background server of the electronic igniter control applet, which contains the address information of legal discharge of fireworks and firecrackers stipulated by the local government. The control applet compares and matches the obtained current location information with the address information in the legal discharge address database. This can be achieved through simple address comparison or more complex geo-fence algorithms. If the match is successful, the user can continue to operate the igniter. If the match fails, the operation of the igniter is rejected, and corresponding prompt information may be provided. In order to prevent security issues such as location forgery, it may be necessary to combine two-factor authentication, geo-fence verification, etc. to ensure the accuracy and reliability of the match.
