When the change determines that the user has a suction action, the airflow sensor generates a sensing signal to the microprocessor 202. After receiving the sensing signal, the microprocessor 202 controls the power supply module 206 to start and supply power to the atomization device 10 to heat the atomization.装置10。 Device 10. Or, if the activation module 203 is a tact switch, when the user touches the tact switch, the tact switch generates a trigger signal to the microprocessor 202. After the microprocessor 202 receives the trigger signal, it controls the power supply module 206 The atomization device 10 is activated and powered to heat the atomization device 10. Or, if the activation module 203 is a pressure sensor, when the user presses the pressure sensor, the pressure sensor generates a pressing signal to the microprocessor 202. After receiving the pressing signal, the microprocessor 202 controls the power supply module 206 to start and give the mist The atomization device 10 is powered to heat the atomization device 10.

It should be noted that the activation module 203 can be activated only after the touch recognition module 201 passes the user's identity recognition.

Further, the electronic cigarette startup control method of the embodiment of the present invention further includes: outputting a shutdown signal after the electronic cigarette enters the working state; turning off the touch recognition module 201 according to the shutdown signal, and making the touch recognition module 201 enter a sleep state.

Specifically, after the electronic cigarette enters the working state, the microcontroller outputs a shutdown signal to the touch recognition module 201, so that the touch recognition module 201 enters a sleep state. Through this control operation, the touch recognition module 201 can be restarted only when the user re-inputs a predetermined touch operation, otherwise the touch recognition module 201 will not work, effectively preventing false triggering.

Further, the electronic cigarette activation control method further includes: after the electronic cigarette enters the working state, judging whether the user's smoking action is detected; if not, monitoring the current state time of the electronic cigarette; judging whether the current state time meets a preset condition ; If the current state time meets the preset conditions, the power supply device 20 is controlled to power off, so that the electronic cigarette enters the dormant state. Here, detecting whether the user has a sucking action can be realized by detecting whether the activation module 203 is working.
