Description

Technical fields:

[0001] This utility model relates to the field of discharge equipment manufacturing technology, specifically to a high-frequency boost electric field generating device with reasonable structure, low power consumption, and adjustable frequency. Background technology:

[0002] Space electric fields can promote cell activity, and therefore can be used in food and drug preservation and health care. At present, the discharge devices used to generate space electric fields mainly rely on medium and high power transformers, resulting in large overall weight and size of the discharge devices. For example, a 5kV transformer weighs about 12kg, which cannot meet the requirements of miniaturization, portability, and integration into various commercial electrical appliances.

[0003] Furthermore, existing space electric field generating devices rely on a sine wave generation circuit in conjunction with voltage transformation to generate a variable electric field. This means that the stability of the variable electric field signal depends on the processing of the sine wave signal. The resulting electric field has poor stability, and the subsequent modulation circuit is complex. It often requires tedious adjustments based on the real-time characteristics of the voltage, frequency, and current of the sine wave signal, resulting in high costs and unsatisfactory results. Summary of the Invention:

[0004] This invention addresses the shortcomings and deficiencies of existing technologies by proposing a high-frequency boost-based electric field generating device that can significantly reduce the size and weight of equipment and output a stable and variable spatial electric field.

[0005] This utility model achieves its purpose through the following measures:

[0006] A high-frequency boost-based electric field generating device includes a power supply circuit and a discharge power supply. It is characterized by having a positive high-frequency transformer boost circuit and a negative high-frequency transformer boost circuit respectively connected to the discharge power supply, and a high-frequency boost switch control circuit respectively connected to the positive and negative high-frequency transformer boost circuits. The power supply circuit supplies power to the positive and negative high-frequency transformer boost circuits via the high-frequency boost switch control circuit.

[0007] The high-frequency boost converter control circuit of this invention includes a microprocessor, a positive power switch control circuit, and a negative power switch control circuit. The microprocessor is connected to both the positive and negative power switch control circuits. The signal output terminal of the positive power switch control circuit is connected to the control signal input terminal of the positive high-frequency transformer boost converter circuit, and the signal output terminal of the negative power switch control circuit is connected to the control signal input terminal of the negative high-frequency transformer boost converter circuit. The microprocessor uses a single-chip microcomputer or an ARM chip to output switch control signals and PWM signals. The PWM signal is a PWM signal with an adjustable duty cycle and a frequency not exceeding tens of kHz. The duty cycle adjustment range of the PWM signal is 0-100%.

[0008] The positive and negative power switch control circuits of this invention are each equipped with control signals output by a microprocessor to receive and execute these control signals to control the power supply of the positive and negative high-frequency transformer boost circuits to turn on or off. Each of the positive and negative power switch control circuits contains a transistor. Specifically, the positive power switch control circuit includes transistors Q1 and Q2, with transistor Q2 receiving signals from the microprocessor to drive transistor Q1 to turn on / off. The negative power switch control circuit includes transistors Q5 and Q6, with transistor Q6 receiving signals from the microprocessor to drive transistor Q5 to turn on / off.

[0009] The power supply circuit described in this utility model has a power supply voltage range of several volts to several hundred volts, and can be a +24V DC power supply circuit.

[0010] Both the positive and negative high-frequency transformer boost circuits of this invention are equipped with high-frequency transformer chip modules, and the output voltage range is between several hundred to tens of thousands of volts or between negative several hundred to negative tens of thousands of volts.

[0011] The discharge power supply described in this invention is connected to the output terminals of both the positive high-frequency transformer boost circuit and the negative high-frequency transformer boost circuit. The discharge power supply is a discharge plate or a discharge rod.

[0012] In operation, this invention utilizes a power supply circuit to output a DC signal to power the entire device. The DC signal is fed into a positive high-frequency transformer boost circuit and a negative high-frequency transformer boost circuit, respectively. These circuits receive switching control signals or PWM control signals from a microprocessor circuit to control the power supply of their respective circuits. The positive and negative high-frequency transformer boost circuits alternately output positive and negative high-voltage signals, transmitting these signals to a discharge power source connected to the positive high-frequency transformer boost circuit. This creates a large-scale electric field around the discharge power source, where the positive and negative high-frequency transformer boost circuits output high-voltage signals ranging from several hundred to tens of thousands of volts.

[0021] Both the positive high-frequency transformer boost circuit 4 and the negative high-frequency transformer boost circuit 5 of this utility model are equipped with high-frequency transformers, wherein the signal input terminal of the high-frequency transformer is connected to the output terminal of the power supply circuit 1.

[0022] The discharge power supply 6 of this invention is connected to the output terminals of both the positive high-frequency transformer boost circuit 4 and the negative high-frequency transformer boost circuit 5. The discharge power supply 6 is a discharge plate or a discharge rod.

[0023] Example:

[0024] This example provides an electric field generating device based on high-frequency voltage boost, which includes a power supply circuit 1, a discharge power supply 6, a positive high-frequency transformer boost circuit 4 and a negative high-frequency transformer boost circuit 5 respectively connected to the discharge power supply 6, and a high-frequency boost switch control circuit respectively connected to the positive high-frequency transformer boost circuit 4 and the negative high-frequency transformer boost circuit 5. The power supply circuit 1 supplies power to the positive high-frequency transformer boost circuit 4 and the negative high-frequency transformer boost circuit 5 respectively through the high-frequency boost switch control circuit. In this example, the power supply circuit 1 includes a power conversion module U1, which is used to convert the externally input AC signal into the DC signal required by the device. In this example, the power conversion module U1 outputs a 24V DC signal.

[0025] As attached Figure 2As shown, the positive high-frequency transformer boost circuit 4 includes a high-frequency self-excited boost module consisting of a transformer chip T1, a transistor Q4, and peripheral devices, and a rectifier / voltage multiplier module consisting of diodes D1 and D2, capacitors C1 and C3. The output terminal of the high-frequency self-excited boost module is connected to the rectifier / voltage multiplier module. During operation, when transistor Q1 in the positive power switch control circuit 2 is turned on, the positive high-frequency transformer boost circuit 4 outputs a positive high-voltage signal. When transistor Q1 is turned off, the output of the positive high-voltage signal stops. If the negative high-frequency transformer boost circuit 5 outputs a negative high-voltage signal at this time, the negative high-voltage signal is sent to the discharge power supply 6.

[0026] As attached Figure 1 and appendix Figure 2 As shown, the high-frequency boost switch control circuit includes a microprocessor 3, a positive power switch control circuit 2, and a negative power switch control circuit 7. The microprocessor 3 is connected to the positive power switch control circuit 2 and the negative power switch control circuit 7, respectively.

For example, the positive power switch control circuit 2 contains a transistor Q1. When transistor Q1 is turned on, the positive high-frequency transformer boost circuit 4 outputs a positive high-voltage signal. When transistor Q1 is turned off, the positive high-frequency transformer boost circuit 4 does not output a positive high-voltage signal. If the negative high-frequency transformer boost circuit 5 outputs a negative high-voltage signal at this time, the positive high-frequency transformer boost circuit 4 will transmit the negative high-voltage signal output by the negative high-frequency transformer boost circuit 5 to the discharge power supply 6.

[0028] In this example, the negative high-frequency transformer boost circuit 5 consists of two main parts: a high-frequency self-excited boost module including transformer chip T2, transistor Q8 and its peripheral components, and a rectifier / voltage multiplier module including diode D4, diode D5, capacitor C17, capacitor C19 and their peripheral components. When transistor Q5 in the negative power switch control circuit 7 is turned on, the negative high-frequency transformer boost circuit 5 outputs a negative high-voltage signal; when transistor Q5 in the negative power switch control circuit 7 is turned off, the negative high-frequency transformer boost circuit 5 does not output a negative high-voltage signal.

[0029] The power supply 6 is composed of internal conductive metal material and external insulating material. When there is a positive high voltage signal or a negative high voltage signal output in the positive high frequency transformer boost circuit 4, the power supply 6 receives the positive high voltage signal or the negative high voltage signal and forms a large-scale electric field space around the power supply 6.

[0030] Compared with the prior art, this utility model has significant advantages such as reasonable structure, small size, light weight, ability to meet the requirements of integration with industrial or household appliances, and stable spatial electric field.
