Abstract

Claims (19)

1. An aerosol generating system comprising:

a holder device including a cigarette insertion hole formed at one end, and configured to generate an aerosol by heating a cigarette inserted into the cigarette insertion hole; and

a cradle device including an inner space configured to accommodate the holder device, and a terminal configured to supply power to the holder device accommodated in the inner space of the cradle device,

wherein

at least one of the holder device and the cradle device includes at least one attaching member to increase attachment strength between the holder device and the cradle device by using a magnetic force,

wherein the inner space is formed on one side of the cradle device such that when the holder device is accommodated in the inner space of the cradle device, the holder device is capable of tilting between a first position where the cigarette insertion hole is completely concealed by the cradle device and a second position where the cigarette insertion hole of the holder device is completely exposed from the cradle device,

wherein the holder device is coupled with the cradle device by the attaching member when the holder device is accommodated in the inner space of the cradle device, such that power is supplied from the terminal of the cradle device to the holder device regardless of whether the holder device is at the first position or at the second position, and

wherein the holder device is configured to:

monitor a smoking pattern when the cigarette is inserted into the holder device and heating is started after the holder device is separated from the cradle device;

determine whether the monitored smoking pattern satisfies a smoking restriction condition; and

control a heater provided in the holder device to stop heating of the inserted cigarette when the smoking pattern satisfies the smoking restriction condition.

2. The aerosol generating system of claim 1 , wherein

the smoking pattern includes a number of puffs for the inserted cigarette,

the smoking restriction condition includes a puff limit number, and

the holder device is configured to control the heater provided in the holder device to stop heating of the inserted cigarette when the number of puffs reaches the puff limit number.

3. The aerosol generating system of claim 1 , wherein

the smoking pattern includes an operation time of the holder device,

the smoking restriction condition includes an operation limit time, and

the holder device is configured to control the heater provided in the holder device to stop heating of the inserted cigarette when the operation time reaches the operation limit time.
