Method for controlling electronic cigarette with multiple output modes

1. A method for controlling an electronic cigarette with multiple output modes comprising:

determining by a first controller whether button signals are input for a first preset number of times via a button when a system of the electronic cigarette is powered on;

controlling the system to enter a locked state if the button, signals are input for the first preset number of times;

determining by the first controller whether a switch signal for switching between the output modes is input to the first controller via the button under the locked state, the output modes comprising a voltage output mode and a power output mode which are able to be stored in a memory of the first controller; and

switching from a current output mode to a new output mode and storing the new output mode in the memory by the first controller if the switch signal is input, and controlling outputs by the first controller according to the stored output mode after a user unlocks the system and the first controller receives a smoking signal.

2. The method of claim 1 , further comprising:

detecting and determining by the first controller whether button signals are input for a second preset number of times via the button if the switch signal is not input; and

unlocking the system when the system is in the locked state if the button signals are input for the second preset number of times, and determining whether the switch signal for switching between the output modes is input if the button signals are not input for the second preset number of times.

3. The method of claim 1 , wherein the first controller determines that the button inputs the switch signal when the button is pressed for a time period greater than or equal to a first preset time period.

4. The method of claim 1 , wherein the voltage output mode corresponds to one LED, and the power output mode corresponds to another LED; when the output mode has been switched, the first controller controls a corresponding LED to emit light to indicate the current output mode.

5. The method of claim 4 , wherein each of the voltage output mode and the power output mode further corresponds to one symbolic identifier configured to indicate the current output mode.

6. The method of claim 1 , further comprising:

detecting and determining by the first controller whether a smoking signal is input via the button if the button signals are not input for the first preset number of times; and

generating a control signal by the first controller according to a detection signal from a second controller if the smoking signal is input.

7. The method of claim 6 , wherein the first controller determines that the button input the smoking signal when the user presses the button once.

8. The method of claim 6 , wherein the detection signal from the second controller comprises a voltage adjusting signal manually input by the user; after the first controller receives according to the voltage preset by the user.

9. The method of claim 6 , wherein the detection signal from the second controller comprises a voltage sample signal for sampling a voltage of the battery; the second controller transforms the voltage sample signal to an actual battery voltage, and transmits the actual battery voltage to the first controller; the first controller determines whether the actual battery voltage is high enough to heat a coil which is configured to heat the liquid solution.

10. The method of claim 9 , wherein if the first controller determines that the actual battery voltage is high enough to heat the coil, the first controller controls the LED corresponding to the current output mode to emit light with a breathing frequency to indicate a current power of the battery.

11. The method of claim 6 , further comprising:

detecting by the second controller whether the coil configured to heat the liquid solution breaks down; and

stopping outputting by the first controller if the coil breaks down.

12. The method of claim 6 , further comprising:

determining by the first controller whether a time period for pressing the button is greater than a second preset time period during smoking; and

stopping outputting by the first controller if the time period for pressing the button is greater than the second preset time period, and generating a warning signal by the first controller to warn the user.

13. The method of claim 1 , further comprising:

determining whether a USB connector of the electronic cigarette is connected to a charger after the system is powered on; and

controlling the system to enter a charging state if the USB connector is connected to the charger.
