Abstract: The present disclosure provides a method for controlling an electronic cigarette and an electronic cigarette. The electronic cigarette comprises an airflow sensor. The control method comprises: measuring whether a duration of a low-level signal sent by the airflow sensor is greater than a preset threshold; if so, when a high-level signal sent by the airflow sensor is received, responding to the high-level signal so as to control the electronic cigarette to operate; and if not, when a high-level signal sent by the airflow sensor is received, not responding to the high-level signal. In the above control method, it is determined, according to the duration of the low-level signal generated by the airflow sensor, whether to respond to triggering of the high-level signal so as to cause the electronic cigarette to operate.

Abstract: An electronic cigarette includes: an atomizer, defining a liquid storage chamber formed therein; a heating element, communicated with the liquid storage chamber; a power supply, configured for supplying power; a controlling unit, one end of the controlling unit electrically connected with the power supply, the other end thereof electrically connected with the heating element; and a capacitive transducer electrically connected with the controlling unit. Two electrodes are disposed inside the liquid storage chamber for determining an amount of the tobacco liquid in the liquid storage chamber. A using method includes: conducting the electricity and controlling the heating element to atomize the tobacco liquid in the liquid storage chamber; detecting an amount of the tobacco liquid in the liquid storage chamber via the capacitive transducer. When the detected amount of the tobacco liquid reaches a preset value, the electronic cigarette emits alert information or cuts off the electricity.
