The power source 31, the airflow sensor 32, the atomizer 25, the smoke duct 21 and the airflow channel are positioned in the case. When the user sucks the electronic cigarette, the external airflow enters in the first cylinder 30 through the air inlet 332 of the sleeve 33, the external airflow in the case becomes the sensing airflow because of the negative pressure channel formed in the case. The sensing airflow pushes the airflow sensor 32 and the airflow sensor 32 is triggered. In this embodiment, the hollow first conductive pillar 27 has a first channel penetrating a top and a bottom of the hollow first conductive pillar 27.
