Abstract

Claims (39)

1. An aerosol generating apparatus comprising:

a vaporizer including a first heater that generates an aerosol by heating a liquid composition, and configured to discharge the generated aerosol; and

a cigarette inserter configured to receive a cigarette including a plurality of segments, and including a second heater configured to heat a portion of the plurality of segments,

wherein the generated aerosol is discharged toward the cigarette inserter through an airflow passage arranged between the vaporizer and the cigarette inserter, and passes through the cigarette inserted in the cigarette inserter,

wherein at least one material vaporized from the heated portion is added to the aerosol which is delivered to a user's mouth through one end of the cigarette,

wherein the one end of the cigarette is completely exposed out of the cigarette inserter when the cigarette is inserted into the cigarette inserter, and

wherein the plurality of segments comprise:

a first filter segment; and

a tobacco rod comprising a tobacco raw material and disposed downstream of the first filer segment such that the generated aerosol moves from the airflow passage to the tobacco rod through the first filter segment.

2. The aerosol generating apparatus of claim 1 , wherein

the second heater is further configured to heat an inside of the inserted cigarette.

3. The aerosol generating apparatus of claim 1 , wherein

the second heater is further configured to heat an outside of the inserted cigarette.

4. The aerosol generating apparatus of claim 1 , wherein

the second heater is further configured to heat the inserted cigarette according to pulse width modulation (PWM) or a duty cycle of a current supplied from a battery.

5. The aerosol generating apparatus of claim 4 , wherein

the PWM or the duty cycle of the current is previously set.

6. The aerosol generating apparatus of claim 1 , further comprising:

a sensor configured to detect a puff of a user; and

a controller configured to determine, through the sensor, whether the puff of the user has occurred.

7. The aerosol generating apparatus of claim 6 , wherein

the controller is further configured to determine whether a number of puffs of the user is equal to or greater than a preset puff limit number, and according to a result of the determining, determine whether to terminate an operation of the aerosol generating apparatus.

8. The aerosol generating apparatus of claim 6 , wherein

the controller is further configured to stop a heating operation of the vaporizer when a number of puffs of the user is equal to or greater than a preset puff limit number.

9. The aerosol generating apparatus of claim 1 , wherein the vaporizer comprises:

a liquid storage configured to store the liquid composition; and

a liquid transfer means for the liquid composition.

10. The aerosol generating apparatus of claim 9 , further comprising:

a controller configured to control a current to be supplied to the first heater for a preset period of time from when a puff of a user is detected.

11. The aerosol generating apparatus of claim 1 , wherein the plurality of segments further comprise:

a third filter segment disposed downstream of the tobacco rod and comprising a hollow; and

a second filter segment disposed downstream of the third filter segment and comprising at least one aroma capsule.

12. The aerosol generating apparatus of claim 11 , wherein the tobacco rod is taste-controlled, and

wherein at least one of the first filter segment, the tobacco rod, the second filter segment, the third filter segment is flavored.

13. The aerosol generating apparatus of claim 1 , further comprising:

an air inflow passage for air introduced from outside.

14. A cradle comprising:

an inner space configured to receive an aerosol generating apparatus according to claim 1 ; and

a battery configured to supply power to charge the aerosol generating apparatus.
