Embodiment Construction

[0015] figure 1 The working principle of the broad-band digital integrated ultrasonic universal power supply module shown is as follows: the preset signal transmitted from the control panel through the interface circuit and the frequency signal generated by the automatic frequency tracking circuit are generated by the frequency synthesizer to generate the basic ultrasonic signal, and the signal is processed The converter becomes a sine wave signal with adjustable amplitude, and a waveform whose pulse width is modulated by the audio signal amplitude is generated by the PWM circuit. The ultrasonic information in the waveform is recovered and transmitted to the transducer through the output circuit interface. figure 2 It is a schematic block diagram of ultrasonic power supply using wide-band digital integrated ultrasonic general power supply module. The frequency setting, power regulation, low-voltage power supply, high-voltage power supply, power display, frequency display and...

Abstract

The invention relates to a wind band ultrasonic power supply module characterized in that the module adopts a surface-slice type high fidelity digital sound integrated circuit technology, and the module is designed as a universal power supply module in such a way that all ultrasonic circuits are positioned in a metal box that acts as a radiator and has shielding effects. By changing interior circuit parameters that can be preset and a connection method between input and output interface circuits and an external part, a very wide frequency range (15 KHz-60 KHz) is covered and different impedance matching is realized. An aim that piezoelectric type ultrasonic transducers of different types and different working frequency can be matched in one ultrasonic power supply is realized. The independent ultrasonic power supply module, connected with an energy converter and a control panel through a circuit interface, is easy to disassemble and install. The ultrasonic power supply module can be used independently while equipped with a standard control panel. The ultrasonic power supply module can be installed on devices of users or on a production line, bringing convenience to users, and therefore multiple functions can be realized in one device.

Description

Technical field: [0001] The present invention relates to an ultrasonic power supply, especially a kind of ultrasonic transducer that can match different frequencies (15KHz-60KHz) and different types of piezoelectric transducers by adjusting the preset of the internal circuit parameters of the power supply module and the interface circuit connected to the outside. Digital integrated ultrasonic universal power module. Background technique: [0002] In today's world, people's production and life are increasingly inseparable from the application of ultrasound. From household humidifiers (ultrasonic atomization), household dishwashers, washing machines (ultrasonic cleaning) commonly used in daily life by ordinary people, to ultrasonic welding, ultrasonic drilling, ultrasonic polishing, ultrasonic turning, and ultrasonic calendering used in industry And so on, and then to the ultrasonic lithotripsy, ultrasonic scalpel, ultrasonic thrombolysis, etc. used in medical equipment, ther...
