if so, generating a control signal and outputting the control signal, wherein the control signal comprises a first control signal and/or a second control signal, the first control signal is subjected to signal processing by a transducer driving module in the host machine and then drives the ultrasonic transducer to adjust the output power, and the second control signal is subjected to signal processing by an electrode driving module in the host machine and then drives the weak electric stimulation electrode to adjust the output power;
and if not, not generating the control signal.
