[0103] S103, after the mouthpiece switch is turned on, an electrical signal is emitted to obtain the mouthpiece airflow trigger signal.
[0104] The principle and effect of the above technical solution are as follows: An airflow sensing and detection circuit is set up to detect the airflow direction of the cigarette holder through an airflow sensor, obtaining an airflow direction detection signal; based on the airflow direction detection signal, the airflow direction is determined, triggering the cigarette holder switch to turn on or off; when the airflow is in the inhalation direction, the airflow sensor detects the inhalation direction airflow and triggers an inhalation forward conduction drive signal, which in turn triggers the cigarette holder switch to turn on; when the airflow is in the exhalation direction, the exhalation reverse cutoff switch turns off the cigarette holder switch during reverse exhalation; based on the electrical signal emitted after the cigarette holder switch is turned on, the cigarette holder airflow trigger signal is obtained.

The forward conduction pressure control assembly has multi-stage conduction pressure control contacts. The multi-stage conduction pressure control contacts include: a first-stage conduction pressure control contact and a second-stage conduction pressure control contact.
