Description

Technical Field

[0001] This invention relates to the field of electric shock technology, and in particular to a digital frequency conversion electric shock device and its pulse control method. Background Technology

[0002] The main principle of a stun gun is based on the electric shock effect and current conduction. Internally, it typically consists of a high-voltage generator, a capacitor, and electrodes. When the stun gun is activated, the high-voltage generator produces a high-voltage pulse current, which is stored in the capacitor. When the stun gun comes into contact with the target, the capacitor releases the stored electrical energy, forming a high-voltage current pulse. Existing stun guns use LC resonant pulse transformers to generate high voltage at a fixed frequency, lacking frequency conversion characteristics, prone to leakage, and have complex circuits that occupy a large size. Some also use voltage multiplier methods. These have variable and uncontrollable frequencies, resulting in unpredictable harm to the human body. Existing stun guns simultaneously fire two electrodes to strike the target for remote control, but remedial measures are limited if the target is missed. The distance between the two electrodes cannot be changed, making it impossible to apply pressure to the whole body in special circumstances.

[0003] Prior art 1, application number: CN 201310618912.0, discloses a digital frequency converter stun gun and its frequency converter pulse control method, including a digital controller and a pulse output circuit. The pulse output circuit includes a power supply, a half-bridge inverter circuit, a pre-stage transformer, a full-bridge rectifier circuit, a soft-switching circuit, a voltage divider circuit, an LC resonant circuit, a post-stage transformer, and a discharge electrode connected in sequence. The power supply, half-bridge inverter circuit, full-bridge rectifier circuit, soft-switching circuit, voltage divider circuit, and LC resonant circuit are respectively connected to the digital controller through a power supply voltage detection circuit, a half-bridge inverter MOSFET driving circuit, a soft-switching MOSFET driving circuit, a rectified voltage monitoring circuit, and an LC resonant thyristor driving circuit. Although this solves the problems of uncontrollable pulse frequency and low energy utilization in the prior art, and improves the system's working efficiency, reliability, and service life, its pulse output circuit has a complex boost circuit and uses many components; it also requires high-precision potting technology for electronic components, otherwise leakage is likely to occur.

[0004] Prior art two, application number: 201611059845.3, discloses a portable human body electric shock riot control device, including: a wireless communication module, an LCD display module, a real-time clock module, a key input module, a storage device, a power supply, an MCU, a drive circuit, a boost AC converter, a high-frequency resonant circuit, and a high-voltage lead; the wireless communication module, LCD display module, real-time clock module, key input module, storage device, and power supply are electrically connected to the MCU; the MCU, drive circuit, boost AC converter, high-frequency resonant circuit, and high-voltage lead are electrically connected in sequence. Although it can automatically record the electric shock usage, facilitating later query and evidence collection; and can also perform frequency conversion control according to the electric shock target, autonomously selecting the electric shock frequency, intensity, and duration, using high-voltage pulse low-current electric shocks to the human body to achieve the purpose of effective riot control without causing harm to the human body, it is a truly reliable riot control device that can be used in actual combat. However, its high-voltage frequency control performance is poor, and the electrical energy is uncontrollable during the entire electric shock process, making it easy to break free.

[0005] Prior art three, application number: 201811379955.7, discloses a high-voltage pulse power supply for an electric shock device. The first-stage switching power supply mainly consists of a switching transistor Q1 and a transformer T1, while the second-stage switching power supply mainly consists of a discharge transistor G1 and a high-voltage transformer T2. The first-stage switching power supply has multiple sets of DC high-voltage outputs, namely V1, V2, Vn, etc., which are superimposed in series. One set of V1 also serves as the operating voltage for the discharge transistor G1 and the high-voltage transformer T2. The multiple sets of DC high voltages are connected in series with the secondary coils N2 and N3 of the high-voltage transformer T2. When the discharge transistor G1 is working, the multiple sets of DC high voltages will be superimposed with the high-voltage pulse generated by the secondary coil of the high-voltage transformer T2 for output. Although this greatly increases the pulse power output of the high-voltage power supply and enhances the effectiveness of the high-voltage electric shock device, the overall circuit components are relatively large, which is not conducive to further reducing the size of the electric shock device. Moreover, the high voltage only has two terminals, positive and negative, and cannot be switched or controlled.

[0006] Current technologies 1, 2, and 3 suffer from complex boost circuits, increasing manufacturing costs. Furthermore, the limited number of high-voltage positive and negative terminals results in non-switchable control, leading to poor operability. Therefore, this invention provides a digital frequency conversion stun gun and its pulse control method. The high-voltage module operates at 500-2000V, eliminating the need for a subsequent LC resonant transformer. The circuit is relatively simple and compact. The output frequency is variable, the output energy is controllable, and it has multiple shock ports that can be used to target different areas as needed. Summary of the Invention
