Aerosol generating device

An aerosol generating device comprising:

• a cartridge comprising a reservoir for storing an aerosol generating material;
• a heater assembly detachably coupled to the cartridge and configured to heat the aerosol generating material provided from the cartridge to generate an aerosol;
• and
• a body detachably coupled to the heater assembly and comprising a battery configured to supply power to the heater assembly,
• wherein the heater assembly comprises:
• a chamber in fluid communication with the reservoir of the cartridge;
• a wick arranged in the chamber, configured to absorb the aerosol generating material provided from the reservoir, and comprising a first surface facing the reservoir, a second surface arranged in an opposite position of the first surface to face a bottom surface of the chamber, and a side surface surrounding a space between the first surface and the second surface;
• and
• a heater arranged on the first surface of the wick and configured to heat the aerosol generating material absorbed into the wick, and
• wherein the first surface of the wick absorbs the aerosol liquefied in the chamber.
