Control circuit design for ultrasonic cleaning machine:

1. Frequency control circuit: By adjusting the oscillation frequency of the ultrasonic generator, precise control of the cleaning effect is achieved. The frequency control circuit usually adopts phase-locked loop (PLL) technology to ensure the stable and reliable frequency output of the ultrasonic generator.

2. Power control circuit: By adjusting the power output of the ultrasonic generator, it can adapt to cleaning objects of different materials and levels of dirt. Power control circuits typically include components such as power amplifiers and adjustable attenuators to achieve precise adjustment of ultrasonic power.

3. Temperature control circuit: Real time monitoring of the temperature of the cleaning solution and automatic adjustment according to the preset temperature range. The temperature control circuit usually consists of a temperature sensor, comparator, and power regulator to ensure that the temperature of the cleaning solution is maintained within the optimal range.

4. Liquid level control circuit: By monitoring the liquid level in the cleaning tank, it prevents the cleaning effect from being affected by low or high liquid levels. The liquid level control circuit usually uses float switches or liquid level sensors to achieve precise control of the liquid level.
