The memory 120 may store the preset pressure value. The memory 120 may be connected to the controller 100 . The controller 100 may determine whether to reuse the stick 10 by comparing the preset pressure value stored in the memory 120 with the pressure value measured by the force sensor 72 .

Reuse of the stick 10 should be avoided because it degrades smoking quality and increases the risk of ignition of the stick 10 . Therefore, it is possible to improve the smoking quality of the aerosol generating device 1 by using the force sensor 72 , and to prevent ignition due to the reuse of the stick 10 .

23 shows a series of processes in which the stick 10 is inserted into the aerosol generating device 1 and then removed. 24 shows a series of processes in which the used stick 10' is inserted into the aerosol generating device 1 and then removed.

23 and 24 , the stick 10 may be inserted into the aerosol generating device 1 . The other end 713 of the probe 71 may be inserted into the stick 10 inserted into the insertion space 46 . The inserted stick 10 may press the probe 71 . When the stick 10 presses the probe 71 , the probe 71 can move in the longitudinal direction of the probe 71 . The moved probe 71 may be in contact with the force sensor 72 .

When the stick 10 is inserted into the aerosol generating device 1 , the probe 71 may maintain contact with the force sensor 72 . Accordingly, a pressure value may be continuously measured in the force sensor 72 . The controller 100 may determine that the stick 10 is inserted based on the point that the pressure value is continuously measured by the force sensor 72 .

When the probe 71 is inserted into the stick 10 , a hole 10 ″ may be formed in one surface of the stick 10 . For example, a hole 10 ″ may be formed in the lower surface of the used stick 10 ′. The hole 10 ″ may be located at the center of the cross section of the stick 10 ′. The hole 10 ″ may have a shape corresponding to the outer surface of the other end 713 of the probe 71 .

When the used stick 10 ′ is inserted back into the aerosol generating device 1 , the used stick 10 ′ can pressurize the probe 71 . In the process in which the sticks 10 and 10' are inserted into the aerosol generating device 1, the force of the unused stick 10 pressing the probe 71 is that the used stick 10' moves the probe 71. It may be greater than the pressing force. Since a hole 10'' is formed in the used stick 10', the probe 71 can be smoothly inserted into the used stick 10'.

Therefore, the control unit 100 determines whether the stick 10 inserted into the aerosol generating device 1 has already been used by comparing the pressure value measured in the process of inserting the stick 10 with the preset pressure value. can do.
