1results about How to "Reduce false starts" patented technology

The application discloses a control circuit for an electronic cigarette and the electronic cigarette, and the control circuit for the electronic cigarette comprises a heating module, a capacitive sensor, a constant current source, a timing module and a control module; the heating module is arranged in the inside of a shell; the capacitive sensor is arranged in a circuit area of the shell, and the air flow blown by a user along an air channel and an air inlet hole changes the capacitance value of the capacitive sensor; the constant current source charges the capacitive sensor; the timing module is electrically connected with the constant current source and is used for calculating the charging duration of the constant current source to obtain a target charging duration; wherein the target charging duration is determined according to the capacitance value of the capacitive sensor; the control module is electrically connected with the timing module and the heating module, and is used for determining the state information of the capacitive sensor according to the target charging duration and a preset duration range, and controlling the heating module to start or shut down according to the state information. The application can improve the accuracy of starting and shutting down of the electronic cigarette and reduce the start and stop control caused by misoperation.
