Abstract: An electronic cigarette includes an atomizer, an e-liquid cavity, and an airflow sensing device. The airflow sensing device includes a first circuit board, a MEMS airflow sensor, and a main control IC. A second control board includes a first bonding pad and a second bonding pad. The second bonding pad is disposed around the first bonding pad. The first bonding pad includes a first pin and the second bonding pad includes a second pin. Since the first bonding pad is surrounded and sealed by the second bonding pad, the first pin is electrically connected to a capacitance detection port of the main control IC, and the second pin is grounded, condensate is prevented from contacting the first pin, thus preventing the condensate from flowing through a capacitance detection circuit. The main control IC does not detect an increase in capacitance value, which prevent the electronic cigarette from self-starting.
