The second drive signal is used to drive the second ultrasonic transducer 221 on the outer periphery, and the frequency thereof needs to be suitable for cleaning the hand or the like. The frequencies of the first driving signal and the second driving signal may be set by the inventor or adjusted by user definition, which is not limited in this embodiment. As shown in fig. 3, the processor 21 is provided therein with a high power module for driving the second ultrasonic transducer 222 to vibrate, and a low power module for driving the first ultrasonic transducer 221 to vibrate. Specifically, the high-power module inside the processor 21 is configured to output a driving signal to the ultrasonic trigger circuit, and the ultrasonic trigger circuit generates an excitation pulse to trigger the second ultrasonic vibrator 222 to vibrate, so as to emit ultrasonic energy, thereby improving the cleaning efficiency. The low power module inside the processor 21 is configured to output a driving signal to the ultrasonic trigger circuit, and the ultrasonic trigger circuit generates an excitation pulse to trigger the first ultrasonic vibrator 221 to vibrate, so as to emit ultrasonic energy, so as to detect whether an object to be cleaned or a hand of a human body exists below the flow guide cavity 12.

When the tap switch is turned on and water flows through, the micro power generation device 40 generates direct current voltage to supply power for the processor and the ultrasonic device; when the faucet is closed, the water flow stops, the micro-generator 40 no longer generates DC voltage, and the ultrasonic cleaning device automatically stops working.

When the switch of the liquid supply pipeline 50 is turned on, liquid flows into the inlet 111 to impact the micro-generator device, and the micro-generator device 40 converts potential energy of the liquid into electric energy and stores the electric energy, and outputs the electric energy to the ultrasonic device to supply power to the ultrasonic device so as to drive the ultrasonic transducer 22 to start. When the ultrasonic transducer 22 is started, the processor 21 controls to send a first driving signal to drive the first ultrasonic vibrator 221 to vibrate, if a human hand is under the diversion cavity 12 and is cleaning, the human hand reflects the first ultrasonic wave back, the ultrasonic echo detection device can detect the human hand, and at this time, the echo signal is returned to the processor 21, so that the processor 21 sends a second driving signal to drive the second ultrasonic vibrator 222 to vibrate to realize ultrasonic cleaning.

Specifically, the processor 21 may be provided with a plurality of independent control modules, i.e., a high power module and a low power module, and each of the first ultrasonic transducer 221 and the second ultrasonic transducer 222 has an independent control module and a driving circuit. After the liquid supply pipeline 50 is opened, the micro power generation device 40 enables the control system to be powered on, the low-power module, the driving circuit, the amplifier and the analog-digital converter in the programmable logic device automatically start to work, the first ultrasonic vibrator 221 generates and transmits ultrasonic waves, and after the ultrasonic echo detection device detects the ultrasonic echoes, the ultrasonic echo information is processed to judge whether an object to be cleaned exists below the diversion cavity. When an object to be cleaned is found, the high-power module and the driving circuit of the peripheral array elements are automatically turned on to generate high-power ultrasonic waves for cleaning. And at this moment, the first ultrasonic vibrator 221 still works continuously, and when the cleaning object is judged to leave, the control of the high-power module is automatically closed until the object to be cleaned is found again, and the high-power module is automatically opened. Therefore, the power consumption of the system can be reduced, the service life of the equipment can be prolonged, and the safety can be improved. When one-time cleaning is finished and the liquid supply pipeline is closed, the control system is powered off, and the low-power module and the peripheral circuit in the programmable logic device stop working.

In addition, the ultrasonic device can be further provided with a display screen for displaying working state information of the ultrasonic cleaning equipment, such as output power, working frequency, cleaning time and the like, so that the ultrasonic cleaning equipment is more convenient to use.
