Claim 15:
16. A control method of an electronic cigarette equipped with double air pressure sensors according to claim 8, wherein the control method comprises steps of:
(1) presetting, in a microcontroller, values including: a preset switching value of suction force, a preset minimum value of suction force, preset values of suction force levels, and a preset maximum value of standby time;
(2) detecting, by means of a switching air pressure sensor, the suction force in an intake passage during using, converting the suction force into a switching suction force signal, and sending the switching suction force signal to the microcontroller;
(3) determining, by means of the microcontroller, whether the switching suction force signal reaches the preset switching value or not, if yes, go to next step, if no, go back to previous one step;
(4) switching on a micro-controlled switch to power up a power control module, to enter a working state;
(5) detecting, by means of a digital air pressure sensor, the suction force in the intake passage during using, converting the suction force into a digital suction force signal, and sending the digital suction force signal to the microcontroller;
(6) determining, by means of the microcontroller, whether the digital suction force signal reaches the preset minimum value of suction force or not, if yes, go to next step, if no, go back to previous one step;
(7) further analyzing, by means of the microcontroller, a level indicated by the digital suction force signal, based on the preset values of suction force levels;
(8) according to the level indicated by the digital suction force signal, adjusting the power control module by means of the microcontroller, to provide output power corresponding to the level to the heating resistor;
(9) generating an amount of vapor corresponding to the level by means of the heating resistor;
(10) as the suction force disappears after one puff, stopping output of the power control module and entering a standby state to wait for next puff;
(11) determining, by means of the microcontroller, whether standby time exceeds the preset maximum value of standby time or not, if yes, go to next step, if no, go back to the step (5);
(12) switching off the micro-controlled switch to power off the power control module, entering a sleep state and going back to the step (2).
