Reuse of the stick 10 should be avoided because it reduces smoking quality and increases the risk of ignition of the stick 10. Therefore, the smoking quality of the aerosol generating device 1 can be improved by using the force sensor 72, and ignition due to reuse of the stick 10 can be prevented.

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

23 and 24, the stick 10 can be inserted into the aerosol generating device 1. The other end 713 of the probe 71 can be inserted into the stick 10 inserted into the insertion space 46. The inserted stick 10 can pressurize 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 come into contact with the force sensor 72.

When the stick 10 is inserted into the aerosol generating device 1, the probe 71 can maintain contact with the force sensor 72. Therefore, the pressure value can be continuously measured by the force sensor 72. The control unit 100 may determine that the stick 10 has been inserted based on the fact 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 on one side of the stick 10. For example, a hole 10'' may be formed on the lower surface of the stick 10' used. The hole 10'' may be located in 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 reinserted into the aerosol generating device 1, the used stick 10' can pressurize the probe 71. In the process of inserting the sticks (10, 10') into the aerosol generating device (1), the force with which the unused stick (10) presses the probe (71) causes the used stick (10') to press the probe (71). It can 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 and the preset pressure value. can do.
