Abstract (en)
[origin: EP4205580A1] An electronic atomization device, including a mouthpiece (3), an airflow sensor (2), and an activation channel (1) communicating the mouthpiece (3) and the airflow sensor (2). a liquid suction portion (21) is arranged on the section of the activation channel (1) close to the airflow sensor (2), and the liquid suction portion (21) is configured to absorb liquid flowing through the activation channel (1) through capillary force. By providing the liquid suction portion (21) on the section of the activation channel (1) close to the airflow sensor (2) to absorb a leakage liquid flowing to the activation channel (1), the airflow sensor (2) is prevented from being soaked by the leakage liquid, thereby reducing the failure of the airflow sensor (2), and ensuring the smoothness of the activation channel (1).
