Referring to FIG. 8 , the aerosol generating device 10 may determine whether the stick 20 is inserted into the insertion space 130 through the stick detection sensor 151 in operation S810. According to one embodiment, the aerosol generating device 10 may monitor a signal of any one of an inductive sensor and a capacitance sensor. At this time, when it is determined that the stick 20 is inserted into the insertion space 130 based on the monitored signal, the aerosol generating device 10 may monitor the signal of the other one of the inductive sensor and the capacitance sensor. . When the aerosol generating device 10 determines that the stick 20 is inserted into the insertion space 130 based on the signal of the inductive sensor and the signal of the capacitance sensor, the stick 20 is inserted into the insertion space 130. It can be finally determined that it has been inserted.

The aerosol generating device 10 may supply power to the heater 110 when it is determined that the stick 20 is inserted into the insertion space 130 in operation S820. For example, the aerosol generating device 10 may supply power to the heater 110 based on the temperature profile stored in the memory 14 .

Referring to FIG. 9, the aerosol generating device 10, when the insertion of the stick 20 into the insertion space 130 is detected, based on the preset temperature profile 900 until time t1, the heater 110 Power may be supplied to the heater 110 so that the temperature of the temperature rises to the T0 temperature. In this case, the time t1 may correspond to a time when power is supplied for preheating of the heater 110 from the time when the insertion of the stick 20 into the insertion space 130 is detected. Here, preheating may mean maintaining or increasing the temperature of the heater 110 at a certain level after the stick 20 is inserted in preparation for generation of aerosol. Meanwhile, the time period up to the time t1 may be named a preheating period, and the time period after the time t1 may be referred to as a heating period.

The aerosol generating device 10 may maintain the temperature of the heater 110 at a predetermined temperature in the heating section based on the preset temperature profile 900 . At this time, the predetermined temperature may be equal to or higher than the minimum temperature of the heater 110 for generating aerosol. The predetermined temperature may be referred to as a target temperature of the heater 110 in the heating section.

According to an embodiment, the predetermined temperature based on the preset temperature profile 900 may vary over time.

From time t1 to time t2, the predetermined temperature may be set to the temperature T1. Also, from time t2 to time t3 , the predetermined temperature may be set to a T2 temperature lower than the T1 temperature.

Meanwhile, the time t1 to t2 may be referred to as a first heating section, the time t2 to t3 may be referred to as a second heating section, and the time t3 and later may be referred to as a third heating section. In this embodiment, the first to third heating sections are described as examples, but are not limited thereto.

Here, the initial section may refer to a section in which a preset time elapses from the time when the preheating of the heater 110 is finished. For example, the initial section may include a first heating section and a second heating section, which is a time section from time t1 when the preheating of the heater 110 is finished to time t3 when a preset time has elapsed.

When the user inhales the aerosol, outside air may flow into the aerosol generating device 10 . When air introduced from the outside due to the puff passes through the heater 110, the temperature of the heater 110 may be lowered due to the air having a relatively low temperature. At this time, it may take a certain amount of time for the temperature of the heater 110 to rise again to a predetermined temperature. Meanwhile, when the puff is repeated for a short time, the temperature of the heater 110 may be lowered due to air introduced from the outside again before the temperature of the heater 110 rises to a predetermined temperature. At this time, as the temperature of the heater 110 decreases, the amount of aerosol generated through the heater 110 may decrease.

Here, the set value may include at least one of a target temperature and a heating time for the heater 110 . For example, when a section after the initial section is composed of a plurality of heating sections, the aerosol generating device 10 sets at least one of a target temperature and a heating time for the heater 110 corresponding to each heating section after the initial section. can decide

According to an embodiment, the aerosol generating device 10 sets a time longer than the reference time corresponding to the temperature profile, based on the fact that the interval between the puffs detected in the initial interval is less than the predetermined interval, the heating for the interval after the initial interval. time can be determined. In this case, the shorter the interval between puffs detected in the initial section, the longer the heating time in sections after the initial section. On the other hand, the aerosol generating device 10, based on the fact that the interval between puffs detected in the initial interval exceeds the predetermined interval, sets a time shorter than the reference time corresponding to the temperature profile as a heating time for intervals after the initial interval. can decide In this case, the longer the interval between puffs detected in the initial section, the shorter the heating time in sections after the initial section.

According to one embodiment, the aerosol generating device 10 sets a temperature higher than the reference temperature corresponding to the temperature profile, based on the fact that the interval between puffs detected in the initial interval is less than the predetermined interval, and the heater for the interval after the initial interval. The target temperature for (110) can be determined. In this case, the shorter the interval between puffs detected in the initial section, the higher the temperature determined as the target temperature for the heater 110 may be. On the other hand, the aerosol generating device 10 sets a temperature lower than the reference temperature corresponding to the temperature profile, based on the fact that the interval between puffs detected in the initial interval exceeds the preset interval, and the heater 110 for the interval after the initial interval. ) can be determined as the target temperature for In this case, the longer the interval between puffs detected in the initial section, the lower the target temperature in sections after the initial section.

Meanwhile, the interval between puffs and the number of puffs detected in the initial period may correspond to each other. That is, the shorter the interval between puffs detected in the initial section, the greater the number of puffs, and the longer the interval between puffs detected in the initial section, the smaller the number of puffs may be. Accordingly, the aerosol generating device 10 may determine a heating time for a section after the initial section and/or a target temperature for the heater 110 based on the number of puffs corresponding to the interval between puffs detected in the initial section. .

According to an embodiment, the aerosol generating device 10 may determine a representative value of the intervals between puffs detected in the initial interval as the interval between puffs detected in the initial interval.

In operation S850, the aerosol generating device 10 may supply power to the heater 110 based on the set value determined for the section after the initial section.

Referring to FIG. 10 , the aerosol generating device 10 may supply power to the heater 110 so that the temperature of the heater 110 rises to the temperature T0 by time t1 based on a preset temperature profile 900. . In addition, the aerosol generating device 10, from the time t1 to the time t2, which is the first heating section, the temperature of the heater 110 corresponds to the target temperature based on the preset temperature profile 900, the heater 110 can supply power to In addition, the aerosol generating device 10 controls the heater 110 so that the temperature of the heater 110 corresponds to the target temperature T2 temperature based on the preset temperature profile 900 from the time t2 to the time t3, which is the second heating period. can supply power to

Meanwhile, when a puff is generated, the temperature of the heater 110 may be lowered due to air introduced from the outside. The aerosol generating device 10 may check the interval between puffs and/or the number of puffs detected in the first and second heating sections, which are initial sections. For example, the interval between puffs is the average value of the first interval from the time point tp1 to the time point tp2, the second interval from the time point tp2 to the time point tp3, and the third interval from the time point tp3 to the time point tp4, It can be determined by the interval between puffs detected in the initial section. For example, as an interval between puffs, a first interval from a time point tp1 when a puff first occurs to a time point tp2 may be determined as an interval between puffs detected in an initial period.

When the interval between puffs detected in the initial interval is less than the preset reference interval, the aerosol generating device 10, in the third interval after the initial interval, the temperature of the heater 110 is the target temperature based on the temperature profile 900 The set value 1000 may be determined to be maintained higher than the T3 temperature. In addition, the aerosol generating device 10, based on the fact that the number of puffs detected in the initial section exceeds a preset number of times (eg, 3 times), aerosol generating device 10 The generator 10 may determine the set value 1000 so that the temperature of the heater 110 is maintained higher than the target temperature T3 based on the temperature profile 900 in the third section, which is a section after the initial section.

On the other hand, referring to FIG. 11, when the time interval from time tp1 to time tp2, which is the interval between puffs detected in the initial section, exceeds the preset reference interval, the aerosol generating device 10 determines the second section, which is the section after the initial section. In the third section, the set value 1100 may be determined such that the temperature of the heater 110 is maintained lower than the T3 temperature, which is the target temperature based on the temperature profile 900. Based on the fact that the number of puffs is less than the preset number of times (eg, 3 times), the aerosol generating device 10 sets the temperature of the heater 110 to the target temperature based on the temperature profile 900 in the third section, which is the section after the initial section. The set value 1100 may be determined to be maintained lower than the T3 temperature.

Referring to FIG. 12 , an interval between puffs detected in an initial period may be less than a preset reference interval. Also, the number of puffs detected in the initial section may exceed a preset reference number. At this time, based on the interval between puffs and/or the number of puffs detected in the initial section, the aerosol generating device 10 determines that the heating time corresponding to the third section, which is the section after the initial section, is the criterion corresponding to the temperature profile 900.
