Electronic Cigarette and Control Method Therefor
First Claim
1. An electronic cigarette, comprising:
- a heating wire component configured to produce heat, wherein the heating wire component comprises a heating wire having a resistance that varies with temperature;
a power source configured to provide a voltage to the heating wire component; and
a controller electrically coupled to the heating wire component and configured to control the power source to output the voltage;
wherein the controller comprises a temperature detecting module configured to detect the resistance of the heating wire and obtain a real-time temperature of the heating wire component, the temperature detecting module presets an upper limit heating temperature and a lower limit heating temperature;
when the real-time temperature is lower than or equals to the lower limit heating temperature, the controller controls the power source to output a first voltage;
when the real-time temperature is higher than or equals to the upper limit heating temperature, the controller controls the power source to output a second voltage that is lower than the first voltage; and
when the real-time temperature is higher than the lower limit heating temperature and lower than the upper limit heating temperature, the controller controls the power source to maintain a current output voltage.

Abstract
An electronic cigarette and a control method thereof are provided. An electronic cigarette with a heating wire component used for producing heat, where the heating wire component comprises a heating wire having a resistance that varies with temperature; a power source used for providing the heating component with a voltage; and, a controller electrically coupled to the heating wire component and the power source and used for controlling the voltage outputted by the power source. The controller comprises a temperature detection module used for detecting the resistance of the heating wire and thus acquiring the actual temperature of the heating wire component. The temperature detection module presets an upper limit heating temperature and a lower limit heating temperature.
