1. An electronic cigarette controller comprising a control chip, the control chip comprising:
a smoking detecting module configured to detect a capacitance change of an external mouthpiece, wherein when the detected capacitance is greater than a smoking threshold, the smoking detecting module sends a smoking signal to switch on the electronic cigarette, or wherein when the detected capacitance is less than the smoking threshold, the smoking detecting module sends a standby signal to shut down the electronic cigarette; a control module connected to the smoking detecting module, and configured to send drive and control signals according to the smoking signal or stop sending drive and control signals according to the standby signal; a drive module connected to the control module, and configured to receive the drive and control signals and output electric current to drive the electronic cigarette to work; and a tobacco liquid detecting module connected to the control module, and configured to sample an amount value of a tobacco liquid of the electronic cigarette and determine whether the amount value of the tobacco liquid is less than a preset reference value, wherein if the amount value of the tobacco liquid is determined to be less than the preset reference value, the control module stops sending the drive and control signals. |
