The other end of the pusher 40 may be exposed toward the cartridge detection sensor 471 through the other end of the pusher movement path 44.

For example, the pusher 40 and the pusher movement path 44 may have a shape extending vertically. The pusher 40 may be capable of moving up and down. When the second container 30 is coupled to the upper side of the first container 20, the lower part 312 of the second container 30 contacts the top of the pusher 40 and pushes the pusher 40 downward. Accordingly, the lower end of the pusher 40 may be in contact with the cartridge detection sensor 471.

The cartridge detection sensor 471 may transmit a detection signal corresponding to physical contact to the control unit 12. The control unit 12 may determine whether the second container 30 is coupled to the first container 20 based on the detection signal received from the cartridge detection sensor 471.

Accordingly, whether the second container 30 is coupled to the second container 30 can be determined by the cartridge detection sensor 471 without a separate terminal configuration for electrical connection being included in the second container 30 . Accordingly, the configuration of the second container 30 for sensing can be simplified and manufacturing costs can be reduced. In addition, when determining whether or not to couple to the second container 30 using a physical contact method, the accuracy of sensing can be improved because the influence of external noise is small.

The actuator 472 may be pressed by the pusher 40 to transmit physical contact to the cartridge detection sensor 471. The actuator 472 may be formed integrally with the cartridge detection sensor 471. The actuator 472 may protrude long from the cartridge detection sensor 471 toward the pusher 40. The actuator 472 may provide a repulsive force to the pusher 40 in a direction away from the cartridge detection sensor 471. The actuator 472 may provide a repulsive force to the pusher 40 from the other end to one end of the pusher movement path 44. For example, the actuator 472 may provide a repulsive force that pushes the pusher 40 upward.

When the second container 30 is coupled to the first container 20, the pusher 40 can press the actuator 472 toward the cartridge detection sensor 471. When the pusher 40 presses the actuator 472 toward the cartridge detection sensor 471, the cartridge detection sensor 471 can detect physical contact. When the second container 30 is separated from the first container 20, the pusher 40 may move in a direction away from the cartridge detection sensor 471 due to the repulsive force of the actuator 472. At this time, the position of the pusher 40 may be returned to the state before the second container 30 was coupled to the first container 20 .

A sealing film 48 may be formed between the cartridge detection sensor 471 and the pusher movement path 44. The sealing film 48 may be formed between the actuator 472 and the pusher movement path 44. The sealing film 48 may be formed of an elastic material so that its shape may be deformed. For example, the sealing film may be formed of rubber or silicone.

When the actuator 472 pushes the sealing film 48, the sealing film 48 may have a convex shape toward the pusher 40. When the pusher 40 presses the cartridge detection sensor 471, the curvature of the sealing film 48 may decrease or may be deformed to be convex toward the cartridge detection sensor 471. Accordingly, the sealing film 48 can prevent foreign substances such as liquid from leaking around the cartridge detection sensor 471 through the pusher movement path 44.

In the present disclosure, the cartridge detection sensor 471 is described as a contact sensor, but is not limited thereto. According to one embodiment, the cartridge detection sensor 471 may be a non-contact sensor. For example, the cartridge detection sensor 471 may be one of a magnetic proximity sensor, an optical proximity sensor, an ultrasonic proximity sensor, an inductive proximity sensor, a capacitive proximity sensor, and an eddy current proximity sensor.

Accordingly, the wick 25 has little or no shape deformation and can be implemented in various shapes. Additionally, the durability of the wick 25 is improved, and the replacement cycle of the first container 20 including the wick 25 can be increased.

The first core part 251 may extend long in the horizontal direction. The first core part 251 may have a hexahedral shape. The second core part 252 may protrude upward from the first core part 251. The second core part 252 may extend long in the horizontal direction. The second core part 252 may have a hexahedral shape.

The first wick part 251 may be larger than the second wick part 252. The circumference corresponding to the side surface 2512 of the first interlining part 251 may be larger than the circumference corresponding to the side surface 2522 of the second interlining part 252.

The heater 2531 may be attached to the first wick part 251. The heater 2531 may form a pattern on the lower surface 2513 of the first wick part 251. The heater 2531 may form various patterns along the longitudinal direction of the first wick part 251. Both ends of the heater 2531 may be adjacent to both ends of the first wick part 251.

A pair of first terminals 2533 may be formed at both ends of the heater 2531. The first terminal 2533 may be coupled to the lower surface of the first wick part 251. A pair of first terminals 2533 may be adjacent to both ends of the first wick part 251. The first terminal 2533 may protrude downward from the first wick part 251.

The first terminal 2533 may be in contact with the second terminal 223 to electrically connect the heater 2531 and the second terminal 223. The second terminal 223 may support the first terminal 2533 and the lower surface 2513 of the first wick part 251.

For example, the aerosol generating device 100 may determine that a predetermined condition is met when the accumulated number of puffs related to the cleaning function is more than a predetermined number (eg, 1000). When the cleaning function is executed, the aerosol generating device 100 may initialize the accumulated number of puffs in relation to the cleaning function. Meanwhile, the predetermined number of times may be determined according to the number of times the cleaning function has been executed. For example, in response to an increase in the number of times the cleaning function has been executed, the predetermined number of times may decrease.

The aerosol generating device 100 may perform a cleaning operation in operation S750, based on satisfying a predetermined condition related to the cleaning function. Here, the cleaning operation may mean an operation of removing impurities generated by the generation of aerosol and accumulated in the wick 25. For example, the aerosol generating device 100 may supply power to the heater 2531 according to a temperature profile corresponding to the cleaning function. At this time, the maximum value of the target temperature for the heater 2531 (e.g., 300°C), which is determined according to the temperature profile corresponding to the cleaning function, may exceed the maximum value of the target temperature for aerosol generation (e.g., 220°C).
