Abstract

A vaporizer includes a liquid storage configured to store a liquid composition, an aerosol generator coupled to one end of the liquid storage, and including a wick configured to absorb the liquid composition from the liquid storage, a liquid heater configured to generate aerosol by heating the wick, an aerosol chamber surrounding the wick and the liquid heater, an inlet through which external air is introduced into the aerosol chamber, and an outlet through which the aerosol generated in the aerosol chamber is discharged, and an air supplier configured to supply the external air to the aerosol generator, and including a first opening connected to the inlet of the aerosol generator and a second opening that is opposite to the first opening and connected to the outside at a position spaced apart from the first opening along a direction from the one end to another end of the liquid storage.
