Claim 11:
12. The control circuit of claim 11, wherein
the power supply capacitor is configured to supply power to the control chip; the airflow sensor is configured to sense an intensity of airflow through the second end, and output an airflow intensity signal to the logic controller through the first end; the logic controller is configured to receive the airflow intensity signal output from the first end of the airflow sensor, control ON/OFF state of the switch tube according to the airflow intensity signal, and control a switch frequency and/or an on-duty ratio of the switch tube according to the airflow intensity signal to adjust a power of the atomization module; and
wherein, when a signal intensity of the airflow intensity signal is less than a preset value, the logic controller controls the switch tube to be in an OFF state; when the signal intensity of the airflow intensity signal is greater than or equal to the preset value, the logic controller controls the switch tube to be in an ON state.
