Electronic cigarette and method for reminding charging therein

A method for reminding charging for an electronic cigarette, wherein comprises following steps:

• detecting the remaining capacity of a power supply battery, and sending a value of the remaining capacity to a microcontroller by a power detection module;
• comparing the value with a preset value in the microcontroller, and controlling the charging prompt module to send a charging prompt signal when the value is lower than the preset value by the microcontrollers;
• wherein the charging prompt signal comprises an airflow charging prompt signal;
• the airflow charging prompt signal is transmitted by following way:
• opening or closing an airflow channel with an preset frequency to transmit the airflow charging prompt signal, when the value is lower than the preset value, and a smoking signal has been received;
• wherein the method of opening or closing the airflow channel with the preset frequency comprises:
• supplying power to an electromagnet according to the preset frequency, the electromagnet is energized and producing magnetic force to attract an elastic cylinder fitted with the electromagnet, to open or close the airflow channel of the electronic cigarette with the preset frequency.

• wherein a lamp is arranged on one end opposite to smoking end of the electronic cigarette, which simulates burning of tobacco when smoking and uses as the displaying prompt element at the same time;
• when a smoking action is detected by the microcontroller, the microcontroller further controls the lamp to glow continuously for a period of time, meanwhile compares the value with the preset value;
• when the value is lower than the preset value, the microcontroller further controls the lamp to glow flickeringly or emit a light of different color when smoking.
