[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings. The following description is used to describe specific embodiments to further illustrate the present invention, and should not be construed as a limitation to the present invention.

[0024] figure 1 The boost circuit for a pet trainer of the present invention is schematically shown. Specifically, the circuit includes a power supply, a boost circuit connected in series with the power supply, an energy storage circuit connected in series with the power supply, a discharge circuit, and a control unit. Hereinafter, the boost circuit will be described in detail with reference to the accompanying drawings.

[0025] The power supply is a DC power supply for supplying power to the boost circuit. The power supply here can be a single or single-cell lithium battery, multiple or multiple lithium batteries, multiple nickel-hydrogen batteries, multiple button cell batteries, etc. The power supply can also be a rechargeable battery. Preferably, the power supply voltage does not exceed 12V.

[0026] The boost circuit includes a boost switch S1 and a boost inductor L1 connected in series for storing electrical energy in the boost inductor L1 when the boost switch S1 is closed. Preferably, it also includes a boost switch S1 and a boost inductor L1. The oscillating capacitor C1 connected in parallel with the voltage inductor L1, and the boost diode D1 connected in parallel with the boost switch S1; the energy storage circuit includes a boost inductor L1, a current control diode D2, and an energy storage capacitor C2 connected in series. When the voltage switch S1 is opened, the power supply and the electric energy stored on the boost inductor L1 are superimposed to form a high voltage higher than the power supply voltage, and the electric energy generated by the high voltage is stored in the energy storage capacitor C2 through the current control diode D2.

[0027] The working principle of the boost loop and the energy storage circuit is: the control unit sends out an oscillating signal to control the boost switch S1. When the oscillating signal is at a high level, the boost switch S1 is closed. At this time, the inductance loop is turned on to proceed. Energy storage; when the oscillating signal is at a low level, the boost switch S1 is disconnected. At this time, the energy storage circuit is disconnected. The power supply and the electric energy stored in the inductor L1 are superimposed to form a high level higher than the power supply voltage. It is stored in the second capacitor C2 via the second diode D2. Through the first switch continuously closing and opening according to the oscillation frequency of the control signal, the second capacitor C2 can maintain the above voltage, so that during normal operation, the electric energy stored on the second capacitor C2 is basically unchanged, and the voltage at both ends thereof The value is maintained at around 200VDC.

[0028] The discharge circuit includes an energy storage capacitor C2, a current limiting resistor R1, a discharge switch S2, a positive output electrode, and a negative output electrode, which are used to release the electric energy stored in the energy storage capacitor C2 when the discharge switch S2 is closed; The electrode and the negative output electrode directly contact the exposed part of the user’s body, such as the skin; the control unit controls the closing and closing of the discharge switch S2 by generating an oscillating signal. When the discharge switch S2 is closed, the discharge circuit is turned on and stored in The electric energy on the second capacitor is transmitted to the user through the first current-limiting resistor, the positive terminal output electrode and the negative terminal output electrode to form a stimulating current on the user. The current-limiting resistor R1 is a preset fixed-value resistor. Its resistance is determined through calculations and experiments for many times. The purpose is to limit the output current generated by the discharge circuit and prevent excessive output current from causing damage to the trained pet. Since the voltage value at both ends of the second capacitor C2 is maintained at about 200 VDC, the generation of high-voltage arc is completely avoided, so the present invention can ensure the safety of the user while generating stimulating current.

[0029] The control unit includes a controller that outputs an oscillation signal after receiving a trigger signal, and is used to provide a control signal for controlling the closing and opening of the boost switch S1 and the discharge switch S2, and the control signal is an oscillation signal. Wherein, the control signal includes a first control signal for controlling the boost switch S1 and a second control signal for controlling the discharge switch S2, and the first control signal and the second control signal have different oscillation frequencies. Preferably, See figure 2 The frequency of the first control signal is twice the frequency of the second control signal, so that the booster circuit, the energy storage circuit and the discharge circuit can cooperate well to generate a stable current.

[0030] Preferably, the controller can generate oscillation signals with no less than three different frequencies. This is because the amount of charge stored in the capacitor q=I*t, where I is the circuit current, and t is the power-on time. Changing the frequency of the oscillating signal can change the charging time of the second capacitor C2 and the charge that the controller can store In turn, change the voltage of the discharge circuit. Oscillating signals of different frequencies correspond to different output currents, and different gear strengths can be achieved by precisely controlling the frequency of this oscillating signal.

[0031] Correspondingly, the present invention also provides a pet training device, including a remote control terminal and a receiving terminal, wherein the receiving terminal includes the above-mentioned boost circuit.

[0032] The present invention provides a booster circuit that can replace the transformer in the prior art, utilizes the energy storage effect of the LC circuit, boosts the DC low voltage of the power supply to about 200V through a reasonable circuit design, and can accurately control the discharge The on-off time of the circuit accurately controls the output of the corresponding amount of charge, so as to achieve gears with different energies. In addition, the present invention only needs a small inductor, two diodes, resistors, capacitors and other simple electrical components to achieve. Compared with the prior art, the circuit is greatly simplified, the volume of the product is reduced, and the weight of the product is greatly reduced.
