A control circuit, an electronic cigarette and a method for controlling the electronic cigarette, the control circuit includes at least one airflow sensor, a microcontroller, a battery, an audio module and an indication unit; the airflow sensor for collecting an airflow signal, converting the airflow signal into a smoking signal and sending the smoking signal to the microcontroller, the microcontroller is used for controlling the audio module to give out hookah-simulating water sounds according to the received smoking signal and simultaneously controlling the indication unit to display a smoking color; and the microcontroller is further used for controlling the indication unit to display different indication colors according to different charging states of the battery. Therefore water sounds can be given out by electronic simulation, and the function of electronically simulating real hookah water sounds is conducive to usage of the electronic cigarette and smoking cessation.
