Abstract

According to an exemplary embodiment, provided is an aerosol generation apparatus including: a liquid cartridge comprising a storage unit configured to store an aerosol-generating substrate which is liquid-type and an atomizer configured to generate aerosol by heating the aerosol-generating substrate; a mouth tip located at one end of the aerosol generation apparatus and comprising a filter unit configured to adsorb at least one material included in the generated aerosol; and an aerosol heating unit configured to heat the generated aerosol when the generated aerosol is inhaled by a user through the mouth tip.

Claims (25)

1. An aerosol generation apparatus comprising:

a liquid cartridge comprising a storage unit configured to store an aerosol-generating substrate of a liquid-type and an atomizer configured to generate aerosol by heating the aerosol-generating substrate;

a mouth tip located at one end of the aerosol generation apparatus and comprising a filter unit configured to adsorb at least one material included in the generated aerosol; and

an aerosol heating unit configured to heat the generated aerosol when the generated aerosol is inhaled by a user through the mouth tip,

wherein the aerosol is heated by the aerosol heating unit before reaching the mouth tip,

wherein the mouth tip is detachable from the aerosol generation apparatus including the aerosol heating unit,

wherein at least part of the mouth tip is surrounded by the aerosol heating unit when inserted into the aerosol generation apparatus such that the mouth tip is heated by the aerosol heating unit, and

wherein at least part of the mouth tip is surrounded by an aluminum foil which is configured to transfer heat from the aerosol heating unit to the mouth tip.

2. The aerosol generation apparatus of claim 1 , wherein

the aerosol heating unit comprises a separate heater or a heat generation material, which is distinct from a heater included in the atomizer.

3. The aerosol generation apparatus of claim 1 , wherein

the aerosol heating unit is further configured to heat the generated aerosol to a temperature in a range of 20° C. to 40° C.

4. The aerosol generation apparatus of claim 1 , further comprising:

a sensor part comprising at least one of a negative pressure sensor, a proximity sensor, and an infrared sensor; and

an electronic circuit configured to supply power to at least one of the atomizer and the aerosol heating unit according to a signal detected by the sensor part.

5. The aerosol generation apparatus of claim 1 , wherein

the aerosol-generating substrate comprises at least one of an aerosol generation material, nicotine, moisture, and a flavoring material.

6. The aerosol generation apparatus of claim 5 , wherein

the aerosol generation material comprises at least one of propylene glycol (PG) and glycerin.

7. The aerosol generation apparatus of claim 1 , wherein

the aerosol-generating substrate comprises a gel type material or a solid content type material.

8. The aerosol generation apparatus of claim 1 , further comprising:

a battery configured to supply power for operating the aerosol generation apparatus; and

an electronic circuit configured to control an operation of the aerosol generation apparatus,

wherein the filter unit comprises at least one of an acetate tow filter, a dual filter, a capsule filter, a tube filter, a recess filter, a cavity filter, and a transfer jet nozzle system (TJNS) filter.
