and a vaporizer configured to heat a liquid composition to generate aerosol and discharge the generated aerosol toward the inserted cigarette such that the generated aerosol passes through the cigarette inserted into the cigarette insertion portion, and a cradle for receiving the aerosol generating apparatus. ## Claims ### Claim 1 An aerosol generating apparatus comprising: a vaporizer configured to include a heater that generates an aerosol by heating a liquid composition; and a cigarette inserting portion configured to insert a cigarette including a plurality of segments, wherein the aerosol generated from the vaporizer passes through the inserted cigarette, and wherein the aerosol is in contact with at least one material contained in any one segment of the plurality of segments, so that the aerosol accompanying the at least one substance is delivered to the user's mouth through one end of the cigarette. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 2) The aerosol generating apparatus of claim 2, wherein the controller is configured to control a current to be supplied to the heater for a preset period of time from when a puff of a user is detected. ### Claim 4 (depends on 1) The aerosol generating apparatus of claim 1, further comprising: an air inflow passage which is a passage for air introduced from outside, wherein, the air inflow passage comprises at least one gap, and the at least one gap is controlled to open and close. ### Claim 5 (depends on 1) The aerosol generating apparatus of claim 1, wherein the cigarette comprises: a first filter segment; a tobacco rod comprising an aerosol generating material and a tobacco raw material; a second filter segment comprising at least one aroma capsule; a third filter segment comprising a hollow; and a wrapper. ### Claim 6 (depends on 5) The aerosol generating apparatus of claim 5, 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, and the wrapper is flavored. ### Claim 7 (depends on 1) The aerosol generating apparatus of claim 1, wherein, at least one of the first filter segment and the tobacco rod is wrapped by other wrapper. ### Claim 8 (depends on 1) The aerosol generating apparatus of claim 1, wherein, the cigarette is a shape in which tobacco raw materials are wrapped in a heat conductive material. ### Claim 9 (depends on 8) The aerosol generating apparatus of claim 8, wherein, the heat conductive material is a metal foil comprising an aluminum foil. ### Claim 10 (depends on 1) A cradle comprising: an inner space capable of receiving an aerosol generating apparatus of claim 1; a battery configured to supply power to charge the aerosol generating apparatus; and a control unit. ### Claim 11 An aerosol generating apparatus comprising: a vaporizer comprising a heater configured to generate aerosol by heating a liquid composition; a cigarette insertion portion into which a cigarette comprising a plurality of segments is inserted; a sensor configured to detect a puff of a user through the inserted cigarette; and a controller configured to detect the puff through the sensor and control a current to be supplied to the heater for a predetermined period of time from when the puff is detected. ### Claim 12 (depends on 11) The aerosol generating apparatus of claim 11, wherein the controller is further configured to control a current not to be supplied to the heater when a next puff is not detected for a predetermined period of time after the puff is detected. ### Claim 13 (depends on 11) The aerosol generating apparatus of claim 11, wherein the plurality of segments comprise a first filter segment, a tobacco rod located at a downstream of the first filter segment and comprising a tobacco raw material composed of granules, and a second filter segment located at a downstream of the tobacco rod, wherein the aerosol generated from the vaporizer passes through the first filter segment, the tobacco rod, and the second filter segment. ### Claim 14 (depends on 13) The aerosol generating apparatus of claim 13, wherein a size of the granules is 0.2 mm to 1.2 mm. ### Claim 15 (depends on 13) The aerosol generating apparatus of claim 13, wherein a filling rate of the tobacco raw material composed of the granules in a cavity of the tobacco rod is 30 to 100%. ### Claim 16 (depends on 13) The aerosol generating apparatus of claim 13, further comprising a third filter segment located at a downstream of the second filter segment, wherein at least one of the second filter segment and the third filter segment comprises at least one aroma capsule. ### Claim 17 (depends on 11) The aerosol generating apparatus of claim 11, further comprising a cigarette detection sensor located on one side of the cigarette insertion portion to detect whether the cigarette is inserted, wherein the cigarette detection sensor is any one of a capacitive sensor, an inductance sensor, and a proximity sensor. ### Claim 18 (depends on 11) The aerosol generating apparatus of claim 11, wherein the controller is further configured to determine whether a number of puffs of the user is greater than or equal to a preset puff limit number and determine whether to terminate an operation of the aerosol generating apparatus according to a result of the determining. ### Claim 19 (depends on 18) The aerosol generating apparatus of claim 18, wherein the controller is further configured to stop a heating operation of the vaporizer when the number of puffs of the user is greater than or equal to the preset puff limit number. ### Claim 20 (depends on 11) The aerosol generating apparatus of claim 11, wherein the vaporizer comprises a liquid storage unit storing the liquid composition, a liquid transfer means configured to transfer the liquid composition to the heater, and an airflow passage arranged to discharge the aerosol generated by the heater toward the inserted cigarette.
