8 is a flowchart illustrating the operation of an aerosol generating device according to an embodiment of the present disclosure, and FIGS. 9 to 11 are referenced for description of the operation of the aerosol generating device according to an embodiment of the present disclosure. it is a drawing

Referring to FIGS. 8 and 9 , the aerosol generating device 10 may detect a puff in operation S810. The puff sensor 151 of the aerosol generating device 10 may detect the first puff and the second puff. The aerosol generating device 10 may detect the first puff and the second puff based on the signal 901 output by the puff sensor 151 .

The second puff p ₁ may be a puff generated next after the first puff p _f has occurred. For example, other puffs may not be detected between the first puff p _f and the second puff p ₁ detected by the puff sensor 151 . For example, the second puff p ₁ may be detected within several seconds or several tens of hours after the first puff p _f occurs. For example, the second puff p ₁ may be a puff that is generated by a user's inhalation after the cartridge 200 is left unused for a long time after the first puff p _f is generated.

The aerosol generating device 10, in operation S820, detects a first puff through the puff sensor 151 and detects a second puff occurring after the first puff, and detects a gap between the first puff and the second puff. An elapsed time (T _count ) may be counted, and the counted elapsed time (T _count ) may be compared with a first set time (T _S1 ).

The aerosol generating device 10 starts counting the time from the time point when the first puff is detected (T ₀ ), stops the count at the time point when the second puff is sensed (T ₁ ), and passes the counted value It can be determined by time (T _count ). The aerosol generating device 10 may calculate the elapsed time by starting counting whenever a puff is sensed and stopping counting when the next puff is sensed. The first set time T _S1 may be previously stored in the memory 14 of the aerosol generating device 10 . The aerosol generating device 10 compares the elapsed time T _count with the first set time T _S1 stored in the memory 14, and the elapsed time T _count is equal to or longer than the first set time T _S1 It can be judged whether or not

When it is determined that the elapsed time T _count is greater than or equal to the first set time T _S1 , the aerosol generating device 10 supplies the second electric power P ₂ to the heater 131 in operation S830, (131) can be heated. The battery 16 of the aerosol generating device 10 may supply the second power P ₂ to the heater 131 . The second power P ₂ may be higher than the first power P ₁ .

When the first electric power P ₁ is supplied to the heater 131 for a predetermined period of time, the heater 131 may be heated to a temperature equal to or higher than the vaporization temperature of the aerosol generating material. The aerosol generating material may be heated and vaporized by the heated heater 131 . When the second power P ₂ is supplied to the heater 131 for a predetermined time, the heater 131 may be heated to a temperature equal to or higher than the vaporization temperature of the aerosol generating material. When the second power P ₂ is supplied to the heater 131 for a certain period of time, the heater 131 may be heated to a higher temperature than when the first power P ₁ is supplied for a certain period of time.

The aerosol generating device 10 may include a container 220 accommodating an aerosol generating material. The container 220 may be formed in the cartridge 200 . The aerosol generating material accommodated in the container 220 may be disposed inside the container 220 or disposed adjacent to the container 220 and impregnated with a liquid delivery means communicating with the inside of the container 220. The heater 131 may be formed in a structure that winds the liquid delivery means.

When the cartridge 200 is left unused for a long time, the liquid delivery means may be impregnated with a large amount of aerosol generating material leaked from the container 220 of the cartridge 200.

By supplying the second power (P ₂ ) higher than the first power (P ₁ ) to the heater 131, the heater 131 heats the liquid delivery means to a high temperature, thereby transferring the liquid of the cartridge 200 that has not been used for a long time. The aerosol-generating substances impregnated in the means can be effectively vaporized.

Supplying the first power (P ₁ ) or the second power (P ₂ ) to the heater 131 is a constant size of the first power (P ₁ ) or the second power (P ₂ ) for each puff. It may mean supplying to the heater 131 . On the other hand, supplying the first power (P ₁ ) or the second power (P ₂ ) to the heater 131 is the first power (for example, 2 seconds) for a predetermined time (eg, 2 seconds) from the time when the puff occurs. P ₁ ) or the second power (P ₂ ) is supplied to the heater 131, and after a predetermined time has elapsed, power lower than the first power (P ₁ ) or power lower than the second power (P ₂ ) is supplied to the heater 131 . It may mean supplying to (131). However, a method of supplying the first power P ₁ or the second power P ₂ to the heater 131 is not limited thereto.

Referring to FIG. 10, the aerosol generating device 10, when it is determined that the elapsed time T _count is greater than or equal to the first set time T _S1 , the second power is provided only for the set number of puffs (the first set number). (P ₂ ) may be supplied to the heater 131 (1002 in FIG. 10).

The aerosol generating device 10 may detect, through the puff sensor 151, puff(s) of a first set number N ₁ occurring after the second puff. The aerosol generating device 10, based on the elapsed time T _count being equal to or longer than the first set time T _S1 , for the puff(s) from the second puff to the first set number N ₁ , the heater ( 131) may be controlled to supply the second power P ₂ .

In addition, according to another aspect of the present disclosure, the controlling operation to supply the second power includes detecting, through the puff sensor 151, puffs of a first set number of times occurring after the second puffs. movement; controlling supply of second power to the heater 131 from the second puff to the puffs of the first set number of times, based on the fact that the elapsed time is greater than or equal to the first set time; and controlling so that the first power is supplied to the heater 131 for at least one puff that occurs after the first set number of puffs.

Certain or other embodiments of the present disclosure described above are not mutually exclusive or distinct from each other. Certain or other embodiments of the present disclosure described above may be combined or used in combination with each component or function.

For example, configuration A described in a specific embodiment and/or drawing may be combined with configuration B described in another embodiment and/or drawing. That is, even if the combination between the components is not directly explained, it means that the combination is possible except for the case where the combination is impossible.

The above detailed description should not be construed as limiting in all respects and should be considered illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
