Abstract
An aerosol generating device includes: an aerosol generating material reservoir configured to store an aerosol generating material; an atomizer configured to atomize the aerosol generating material into an aerosol; an inflow passage configured to provide fluid communication between outside of the aerosol generating device and the atomizer; a discharge passage which is surrounded by a passage wall and through which air introduced from the outside through the inflow passage and the aerosol are discharged out of the aerosol generating device; and at least one convex surface configured to guide the aerosol to the outside of the aerosol generating device by Coanda effect, so that the discharge rate of the aerosol may be enhanced and liquefaction of the aerosol in the airflow passage may be minimized.
