ELECTRONIC CIGARETTE AND CIRCUIT USED IN THE SAME

摘要

The present invention provides an electronic cigarette includes a power supply, a micro-controller and a heater for heating and producing smoke, which are orderly and electrically connected to constitute a loop; further includes at least two airflow sensors electrically connected to the micro-controller for sensing the airflow in the electronic cigarette and outputting sensed signal, the micro-controller conducts the loop according to sensed signal. The electronic cigarette and its circuit utilize at least two airflow sensors electrically connected to the micro-controller and sensing the airflow in the electronic cigarette and outputting sensed signal such that the micro-controller conducts the loop according to the sensed signal to achieve exponentially reducing malfunction rate of electronic cigarettes as a result of the airflow sensor failure. The electronic cigarette reduces the quality risks of electronic cigarette. The electronic cigarette and the circuit unlikely cause malfunction, and have reliable quality and stable performance.
