The first washer 42 can be disposed along the periphery of the upper portion of the second inner wall 432. The first washer 42 can be formed of an elastic material. The first washer 42 prevents liquid contained in the container 413 from leaking into the liquid evaporation space 49.

[0072] The first washer 42 may extend along the second inner wall 432 in the longitudinal direction. Furthermore, the elongated first washer 42 and the first inner wall 412 may contact each other. The extension portion 421 of the first washer 42 (see reference) Figure 13 It can be inserted into the gap between the second inner wall 432 and the first inner wall 412 so that it can be compressed therebetween. Therefore, it can prevent the liquid in the container 413 from leaking into the liquid evaporation space 49.

[0073] The second washer 44 can be inserted into the gap between the first outer wall 411 and the second outer wall 431 so as to be compressed therebetween. The second washer 44 can extend along the periphery of the base 45. The second washer 44 can be inserted into the gap between the second outer wall 431 and the base 45. The second washer 44 can be inserted into the gap between the first outer wall 411 and the base 45. The second washer 44 can prevent liquid contained in the container 413 from leaking out of the cylinder 40.

[0074] The second gasket 44 may include a compression portion 441 and an extension portion 442. The compression portion is inserted into the gap between the flange 434 and the transverse surface 458 of the base 45, and the extension portion extends from the compression portion 441 along the transverse surface 458 of the base 45 and is inserted into the gap between the base 45 and the first outer wall 411. Therefore, leakage of liquid from the container 413 into the gap between the lower housing 43 and the base 45 or into the gap between the base 45 and the upper housing 41 can be prevented.

[0075] A stepped portion 418 may be formed on the inner surface of the first outer wall 411. The stepped portion 418 may engage with the flange 434. The stepped portion 418 may press against the flange 434 of the second outer wall 431. The stepped portion 418 may press against the second washer 44. When the first outer wall 411 of the upper housing 41 is attached to the base 45, the stepped portion 418 of the first outer wall 411 may press against the flange 434 of the second outer wall 431 and the second washer 44. Therefore, when the upper housing 41 and the base 45 are attached to each other, the second washer 44 can be compressed and can come into close contact with the first outer wall 411, the second outer wall 431, and the base 45.

[0076] The flange 434 can be formed such that the end of the second outer wall 431 is bent and extends outside the lower housing 43. The flange 434 can be formed such that the upper end of the second outer wall 431 is bent and extends outward. The flange 434 can be connected to the stepped portion 418. The flange 434 can contact the stepped portion 418. When the first outer wall 411 is connected to the base 45, the flange 434 can be pressed by the stepped portion 418. The lower side of the flange 434 can contact the second washer 44.

[0077] The compression protrusion 410 can protrude from the first inner wall 412 into the interior of the upper housing 41. The first washer 42 can be inserted into the gap between the compression protrusion 410 and the second inner wall 432. The lower surface of the compression protrusion 410 can compress the first washer 42. The compression protrusion 410 can compress the compression portion 423 of the first washer 42.

[0078] The compression protrusion 410 can extend to surround the inner periphery of the compression portion 423 of the first gasket 42. The compression protrusion 410 extending along the first gasket 42 can be adjacent to the second inner wall 432. The compression protrusion 410 extending along the first gasket 42 can contact the second inner wall 432. Therefore, leakage of liquid from the container 413 into the liquid evaporation space 49 can be prevented.

[0079] The stop 419 may be formed inside the first inner wall 412. The stop 419 may be integrally formed with the compression protrusion 410. The stop may be formed above the compression protrusion 410. The stop 419 may be formed below the support rib 415. The stop 419 may be formed between the compression protrusion 410 and the support rib 415. The stop 419 may be positioned adjacent to the compression protrusion 410.

[0080] The upper surface of the stop 419 can support the rod 10 inserted into the insertion space 46. The stop 419 can prevent the rod 10 from being inserted into the insertion space 46 beyond a predetermined depth. Multiple stops 419 can be formed. Multiple stops 419 can be integrally formed with each other. Multiple stops 419 can be arranged at the same vertical position along the longitudinal direction of the upper housing 41. Multiple stops 419 can be arranged along the inner periphery of the upper housing 41. Multiple stops 419 can contact the lower surface of the rod 10.

[0081] refer to Figure 11 and Figure 12 The aerosol generating device 1 may include a probe 71, a first seal 81, and a second seal 82. The upper housing 41 may include a support 420. The lower housing 43 may include a recessed portion 435, a retainer 436, and a hole 437.

[0082] The probe 71 may be elongated. The probe 71 may extend in the longitudinal direction of the upper housing 41. The probe 71 may be configured to move in the longitudinal direction of the upper housing 41. The probe 71 may penetrate the lower housing 43. The probe 71 may penetrate the base 45. The probe 71 may move from the insertion space 46 to the outside of the lower housing 43.

[0083] Probe 71 may include an end 714 adjacent to force sensor 72 (see reference). Figure 14 The first portion 715 extends from end 714 and moves through a hole 437 in retainer 436; the opposite end 713 is formed opposite to end 714 and is located in insertion space 46; the second portion 716 extends from opposite end 713 and moves in the longitudinal direction of insertion space 46; the third portion 717 interconnects the first portion 715 and the second portion 716 and intersects the longitudinal direction of the first portion 715 or the second portion 716; and the latch rib 712.

[0084] The opposite end 713 of probe 71 can be located at the center of the cross-section of insertion space 46, which extends in the longitudinal direction of probe 71. The opposite end 713 of probe 71 can contact the center of rod 10 inserted into insertion space 46. The opposite end 713 of probe 71 can be inserted into the center of rod 10. Therefore, probe 71 can move a distance in the longitudinal direction of probe 71 corresponding to the length of rod 10 inserted, and the force used by rod 10 to push probe 71 during insertion can be transmitted to force sensor 72.

[0085] The end 714 of probe 71 may be adjacent to the second inner wall 432 of the lower housing 43. When viewed in the longitudinal direction of probe 71, the end 714 and the opposite end 713 of probe 71 may be positioned on different axes. When viewed in the longitudinal direction of probe 71, the end 714 of probe 71 may be located outside the insertion space 46, and the opposite end 713 of probe 71 may be located inside the insertion space 46 (at its center).

[0086] The first portion 715 can extend from the end 714 of the probe 71. The first portion 715 can move through the hole 437 in the retainer 436. The first portion 715 can extend in the longitudinal direction of the insertion space 46.

[0087] The second part 716 can extend from the opposite end 713 of the probe 71. The second part 716 can extend in the longitudinal direction of the insertion space 46. The second part 716 can move in the insertion space 46 along the longitudinal direction of the insertion space 46.

[0088] The third portion 717 can be bent to interconnect the end 714 of the probe 71 located at the center of the insertion space 46 and the opposite end 713 of the probe 71 adjacent to the second inner wall 432. The third portion 717 can be elongated in a direction intersecting the longitudinal direction of the probe 71. For example, the third portion 717 can be elongated in a direction perpendicular to the longitudinal direction of the probe 71.

[0089] Meanwhile, the third part 717 can be located above the core 47. Therefore, it is possible to prevent liquid or droplets falling from the core 47 from leaking out of the cylinder 40 along the third part 717.

[0090] The latch rib 712 may protrude from the transverse surface of the probe 71 in a direction intersecting the direction of movement of the probe 71. The latch rib 712 may be engaged by the support 420 of the first inner wall 412. The latch rib 712 may extend in the longitudinal direction of the probe 71. The latch rib 712 may be located below the support 420. The latch rib 712 may be located between the upper housing 41 and the force sensor 72. The latch rib 712 may prevent the probe 71 from moving a predetermined distance or more toward the insertion space 46.

[0091] The first seal 81 may include a membrane 811. The first seal 81 may contact a first inlet 451 in the base 45. The first seal 81 may extend along the periphery of the first inlet 451. The first seal 81 may be inserted into the lower housing 43. The first seal 81 may be inserted into the gap between the second outer wall 431 of the lower housing 43 and the base 45. The first seal 81 may be formed of an elastic material.

[0092] The first seal 81 prevents liquid in container 413 from leaking into the first inlet 451 through the gap between the lower housing 43 and the base 45. Furthermore, because the first seal 81 hermetically seals the periphery of the first inlet 451, the air pressure in the first inlet 451 can be maintained during user inhalation.

[0093] A membrane 811 can be disposed in the first inlet 451. The membrane 811 can be disposed in the flow path of air drawn through the first inlet 451. The membrane 811 can have multiple pores formed therein. Therefore, since the liquid does not pass through the multiple pores, leakage of liquid out of the cylinder 40 can be prevented.

[0094] The probe 71 can be inserted into the second seal 82. The second seal 82 can be supported by the base 45. The second seal 82 can be supported by the lower housing 43. The second seal 82 can prevent liquid from leaking out of the cylinder 40 along the probe 71.

[0095] The support member 420 can project inwardly from the first inner wall 412 of the upper housing 41. The support member 420 can project toward the probe 71. The support member 420 can be positioned adjacent to the lateral surface of the probe 71. When the probe 71 is tilted, the support member 420 can support the lateral surface of the probe 71.

[0096] The recessed portion 435 can be formed such that the bottom surface 430 of the lower housing 43 is recessed into the lower housing 43. When the aerosol generating device 1 is inverted, droplets remaining between the lower housing 43 and the base 45 can accumulate in the recessed portion 435. The recessed portion 435 can prevent droplets from leaking into the first inlet 451.

[0097] A retainer 436 may be formed at the lower housing 43. The retainer 436 may be formed at the second inner wall 432 of the lower housing 43. The retainer 436 may be integrally formed with the lower housing 43. The retainer 436 may have a hole 437 formed therein for the probe 71 to slide through. The retainer 436 may allow the probe 71 to pass through it. The retainer 436 may extend in the longitudinal direction of the probe 71. The hole 437 in the retainer 436 may extend in the longitudinal direction of the probe 71. The hole 437 in the retainer 436 may have a shape corresponding to the cross-section of the probe 71. The hole 437 may support the transverse surface of the probe 71.

[0098] Meanwhile, the support 420 can be located above the latch rib 712 of the probe 71. The support 420, latch rib 712, and retainer 436 can be arranged sequentially in the longitudinal direction of the upper housing 41. The support 420 can be located above the latch rib 712. The retainer 436 can be located below the latch rib 712. Therefore, when the probe 71 moves in its longitudinal direction, the support 420 and retainer 436 can limit the excessive movement of the probe 71.

[0099] refer to Figure 13 The second inner wall 432 of the lower housing 43 may include a notch 439. The first washer 42 may include an extension portion 421, an insertion portion 422, and a compression portion 423.

[0100] A notch 439 may be formed in one end of the second inner wall 432. The notch 439 may be recessed in the longitudinal direction of the upper housing 41. That is, the notch 439 formed in the upper end of the second inner wall 432 may be recessed downwards. A core 47 may be inserted into and disposed within the notch 439. The core 47 may be disposed inside the notch 439. The notch 439 may have a shape corresponding to the appearance of the core 47. Therefore, the core 47 may be positioned between the notch 439 and the insertion portion 422 to ensure close contact with both the notch 439 and the insertion portion 422, thereby preventing liquid leakage.

[0101] The first washer 42 may include: an extension portion 421 that extends from the compression portion 423 along the outer surface of the second inner wall 432 and is inserted into the gap between the first inner wall 412 and the second inner wall 432; a compression portion 423 that is inserted into the gap between the first inner wall 412 and the second inner wall 432; and an insertion portion 422 that extends from the compression portion 423 and is inserted into the notch 439.

[0102] The extension portion 421 can extend from the compression portion 423. The extension portion 421 can extend along the second inner wall 432 in the longitudinal direction. The first inner wall 412 of the upper housing 41 can extend along the extension portion 421. The extension portion 421 can be inserted into the gap between the second inner wall 432 and the extended first inner wall 412.

[0103] The insertion portion 422 can extend downward from the compression portion 423 of the first washer 42. The insertion portion 422 can contact the core 47 disposed in the recess 439. The insertion portion 422 can have a shape corresponding to the appearance of the core 47. Therefore, the insertion portion 422 can be in close contact with the core 47, thereby preventing liquid leakage along the outer surface of the core 47.

[0104] refer to Figure 14 The aerosol generating device 1 may include a first flow path 91, a second flow path 92, and a third flow path 93. Furthermore, the aerosol generating device 1 may include a first gap 225, a second gap 520, a first opening 521, a suction detection sensor 53, a second opening 522, a first inlet 451, a second inlet 433, a battery 58, and a terminal 59.

[0105] A first flow path 91 can be formed by passing through a first gap 225 and a second gap 520. The first gap 225 is located between the insertion hole 21 in the cover 20 and the rod 10, and the second gap 520 is formed between the upper outer shell 30 and the pillar 52. The first flow path 91 can be named the outer shell flow path. Air used to generate the aerosol can be drawn through the first gap 225. The air drawn into the insertion hole 21 can be introduced into the second gap 520 between the upper outer shell 30 and the pillar 52. The air introduced into the second gap 520 can pass through a first opening 521 formed in the pillar 52. That is, the first flow path 91 can sequentially interconnect the insertion hole 21, the second gap 520, and the first opening 521.

[0106] The second flow path 92 can interconnect the first opening 521 and the second opening 522 formed in the column 52. The second flow path 92 can be located inside the column 52. The second flow path 92 can be connected to the first flow path 91. The second flow path 92 can be named the column flow path.

[0107] A third flow path 93 can be formed through the first inlet 451 in the base 45, the second inlet 433 in the lower housing 43, and the area near the core 47. The second inlet 433 can be formed in the third flow path 93. The third flow path 93 can be connected to the second flow path 92. The third flow path 93 can lead from the first inlet 451 to the inserted rod 10. Since the third flow path 93 passes through the core 47, the liquid evaporated by the heater 48 can mix with air. Therefore, the user can inhale aerosol through the rod 10.

[0108] The third flow path 93 can be located between the bottom surface 430 of the lower housing 43 and the base 45. The third flow path 93 can be named the base flow path. The third flow path 93 can form a wide flow path between the lower housing 43 and the base 45 and can ensure sufficient flow velocity.

[0109] Battery 58 (reference) Figure 22 The battery 58 can be installed in the main body 50. The battery 58 can be located in the lower part of the main body 50. The battery 58 can power the heater 48. The battery 58 can power the controller 100. The battery 58 can power the electronic devices included in the aerosol generating device 1. The battery 58 can power the output unit 110, the force sensor 72, and the memory 120.

[0110] Terminal 59 can be connected to battery 58. Terminal 59 can be connected to an external power source. Battery 58 can receive power from an external source through terminal 59.

[0111] Reference Figures 15 to 18 Describe the first flow path 91 and the second flow path 92.

[0112] A first gap 225 can be formed between the insertion hole 21 and the rod 10 inserted into the insertion hole 21. Air can pass through the first gap 225. Air that has passed through the first gap 225 can be introduced into the post 52 through the second gap 520.

[0113] A second gap 520 may be formed between the upper outer shell 30 and the pillar 52. The second gap 520 may be formed near the pillar 52. The surfaces 32 of the upper outer shell 30, the upper surface of the upper shell 41, and the surface 523 of the pillar 52, which together form the second gap 520, may be flat. The second gap 520 may communicate with the first opening 521. The second gap 520 may be formed through a spacer protrusion 31 of the upper outer shell 30.

[0114] The spacer protrusion 31 can form a second gap 520. The spacer protrusion 31 can be adjacent to the first opening 521. The spacer protrusion 31 can protrude from the portion of the upper housing 30 facing the first opening 521. The spacer protrusion 31 can contact the upper housing 41 or the post 52. The spacer protrusion 31 can separate the upper housing 30 and the post 52 from each other. The spacer protrusion 31 can define the width of the second gap 520.

[0115] The first opening 521 allows the first flow path 91 and the second flow path 92 to connect with each other. The first opening 521 allows the second gap 520 and the interior of the column 52 to communicate with each other. The first opening 521 can be formed in the outer surface of the column 52. The first opening 521 can be formed in the upper surface of the column 52. The first opening 521 can be adjacent to the upper housing 41 and the upper outer housing 30.

[0116] The suction detection sensor 53 can sense whether the user is inhaling. The suction detection sensor 53 can be installed in the first flow path 91, the second flow path 92, or the third flow path 93.

[0117] A suction detection sensor 53 can be installed in the second flow path 92. The suction detection sensor 53 can be spaced upwards from the second opening 522. The suction detection sensor 53 can be installed between the first opening 521 and the second opening 522. The suction detection sensor 53 can be located on the inner surface of the column 52 adjacent to the cylinder 40. Therefore, malfunction of the suction detection sensor 53, which could be caused by liquid seepage, can be prevented when the aerosol generating device 1 is tilted or rotated.

[0118] The suction detection sensor 53 can sense the flow of air. The suction detection sensor 53 can be a pressure sensor or a gas flow sensor. The suction detection sensor 53 can be positioned adjacent to either the first opening 521 or the second opening 522. The suction detection sensor 53 can sense the flow of gas through the second flow path 92.

[0119] The second opening 522 allows the second flow path 92 and the third flow path 93 to connect to each other. The second opening 522 can be formed in the surface of the pillar 52 facing the lower housing 43 or the base 45. The second opening 522 can be positioned adjacent to the lower housing 43 or the base 45. The second opening 522 can face the first inlet 451 in the base 45. The second opening 522 can be connected to the first inlet 451 in the base 45. A sealing member (not shown) can be inserted into the gap between the second opening 522 and the first inlet 451. The second opening 522 can be in close contact with the first inlet 451.

[0120] Meanwhile, the second inlet 433 can be offset from the core 47 in the longitudinal (or vertical) direction of the upper housing 41 so as to be positioned on a different axis. That is, the second inlet 433 can be spaced apart from the core 47 in the radial direction or in the horizontal direction. Therefore, since the liquid falling from the core 47 does not flow directly into the second inlet 433, liquid leakage outside the cylinder 40 can be prevented.

[0121] Meanwhile, the hole 437 in the retainer 436 can be offset from the core 47 in the longitudinal (or vertical) direction of the upper housing 41 so as to be positioned on a different axis. That is, the hole 437 can be spaced apart from the core 47 in the radial direction of the hole 437. The core 47 can be located between the hole 437 and the second inlet 433 in the radial direction of the hole 437. Furthermore, the hole 437 and the second inlet 433 in the retainer 436 can be positioned symmetrically with respect to the core 47. Therefore, since liquid falling from the core 47 does not flow directly into the hole 437 in the retainer 436, liquid leakage can be prevented.

[0122] refer to Figure 19 and Figure 20 The aerosol generating device 1 may include a first boss 452, a second boss 438, a wall 453, a first opening 455, a second opening 511, a force sensor 72, a second seal 82, a controller 100, an output unit 110, and a memory 120.

[0123] A first opening 455 may be formed in the base 45. The first opening 455 may also be formed in the bottom surface 457 of the base 45. The first opening 455 may allow the tip 714 of the probe 71 to pass through it. The first opening 455 may be located below the retainer 436. The first opening 455 and the second opening 511 may be arranged along the longitudinal direction of the probe 71.

[0124] A second opening 511 may be formed in the mounting member 51 of the body 50. The second opening 511 may allow the end 714 of the probe 71 to pass through it. The second opening 511 may be located below the first opening 455. A portion of the force sensor 72 may be located in the second opening 511.

[0125] Force sensor 72 can be mounted in body 50. Force sensor 72 can be positioned adjacent to end 714 of probe 71. Force sensor 72 can be located below probe 71. Force sensor 72 may include sensing portion 721, which contacts end 714 of probe 71 when probe 71 moves from insertion space 46 into lower housing 43. Sensing portion 721 of force sensor 72 can be pressed by end 714 of probe 71.

[0126] Force sensor 72 measures the pressure value generated when it comes into contact with probe 71. Force sensor 72 transmits the measured pressure value to controller 100. Force sensor 72 may be designated as pressure sensor 72. A preset pressure value can be stored in controller 100, and controller 100 can compare the pressure value measured by force sensor 72 with the preset pressure value.

[0127] The surface of the sensing portion 721 that contacts the end 714 of the probe 71 can be formed as a curved surface. For example, the sensing portion 721 may include a curved surface that protrudes toward the probe 71. Therefore, even if the probe 71 tilts during its movement, the contact point between the end 714 and the sensing portion 721 can be formed at the center of the sensing portion 721. Furthermore, since a single contact point is formed, the accuracy of the force sensor 72 can be improved.

[0128] The second seal 82 may include a first support portion 821 supported by the base 45, a second support portion 823 supported by the lower housing 43, a connecting portion 822 interconnecting the first support portion 821 and the second support portion 823, and a contact portion 824 that contacts the probe 71.

[0129] The first support portion 821 can be supported by a first boss 452 protruding from the base 45. The lower surface of the first support portion 821 can be supported by the base 45, and the lateral surface of the first support portion 821 can be supported by the first boss 452. The first support portion 821 can be adhered to the base 45.

[0130] The second support portion 823 can contact the lower housing 43. The second support portion 823 can extend along the bottom surface 430 of the lower housing 43. The second support portion 823 can surround the hole 437 in the retainer 436. The second support portion 823 and the contact portion 824 can hermetically seal the hole 437 in the retainer 436, thereby preventing liquid from leaking out of the lower housing 43 through the hole 437 in the retainer 436.

[0131] The first support portion 821 and the second support portion 823 can respectively support the lower surface and the upper surface of the second seal 82. Therefore, even if the probe 71 moves in its longitudinal direction, the second seal 82 can maintain its original position in the longitudinal direction of the probe 71.

[0132] The contact portion 824 may surround the outer surface of the probe 71. The contact portion 824 may be located on the periphery of the probe 71. The contact portion 824 may adhere to the probe 71. The contact portion 824 may extend in the longitudinal direction of the probe 71. The contact portion 824 may prevent liquid that has leaked out of the lower housing 43 from leaking out of the base 45 along the probe 71.

[0133] Meanwhile, the aerosol generating device 1 may include a plurality of protrusions (not shown) extending from the base 45 to support the transverse surface of the second seal 82. These protrusions may be arranged symmetrically relative to the probe 71. The protrusions may be integrally formed with each other to have a boss shape.

[0134] The first boss 452 can protrude from the base 45. The first boss 452 can protrude from the base 45 toward the lower housing 43. The first boss 452 can support the lateral surface of the second seal 82. The first boss 452 can support the outer surface of the first support portion 821. The first boss 452 can maintain the second seal 82 in its original position in the longitudinal direction perpendicular to the probe 71.

[0135] The second protrusion 438 may protrude from the lower housing 43. The second protrusion 438 may protrude toward the base 45. The second protrusion 438 may surround the first protrusion 452. The second protrusion 438 may surround the outer side of the first protrusion 452. The second protrusion 438 and the first protrusion 452 may overlap each other in a direction intersecting the longitudinal direction of the probe 71. For example, the second protrusion 438 and the first protrusion 452 may overlap each other in a direction perpendicular to the longitudinal direction of the probe 71. Therefore, liquid or droplets can be prevented from penetrating the first protrusion 452 from the outside of the second protrusion 438.

[0136] A wall 453 may be formed on the base 45. The wall 453 may protrude from the base 45 toward the second flow path 92. The wall 453 may protrude toward the lower housing 43. The wall 453 may be disposed between the second inlet 433 and the first inlet 451. The wall 453 may prevent droplets from flowing back to the first inlet 451 along the second flow path 92.

[0137] Meanwhile, wall 453 can be bent along the second flow path 92 or in the opposite direction to the second flow path 92. Wall 453 can be bent toward the second inlet 433 or the first inlet 451. Therefore, when the aerosol generating device 1 is lowered or tilted, liquid leakage into the first inlet 451 can be effectively prevented.

[0138] Figure 21 This illustrates a situation where the probe 71 moves from the insertion space 46 to the outside of the lower housing 43 and its end 714 contacts the sensing portion 721 of the force sensor 72.

[0139] When the rod 10 is inserted into the insertion space 46, the probe 71 in contact with the rod 10 can move in the longitudinal direction of the probe 71. As the probe 71 moves, the second seal 82 surrounding the probe 71 can move in the direction of movement of the probe 71. Even if liquid or droplets leak out of the lower housing 43 along the probe 71, the second seal 82 can prevent liquid or droplets from leaking out of the base 45.

[0140] When the tip of probe 71 contacts sensing part 721, the pressure value sensed by force sensor 72 can be transmitted to controller 100. Controller 100 can compare the sensed pressure value with a preset pressure value and determine whether rod 10 is a used rod.

[0141] refer to Figure 22 The aerosol generating device 1 may include a controller 100, an output unit 110, and a memory 120.

[0142] When the pressure value measured by the sensing unit 721 is greater than a preset value, the controller 100 can determine that the rod 10 is new. When the measured pressure value is less than the preset value, the controller 100 can determine that the rod 10 is a used rod. In other words, the controller 100 can determine whether the rod 10 inserted into the aerosol generating device 1 is a used rod based on the pressure value sensed by the force sensor 72.

[0143] Output unit 110 may include display 111, sound output unit 112, and tactile output unit 113. Output unit 110 may be operated by controller 100. After determining that bar 10 is a used bar, controller 100 may output information indicating that bar 10 is reusable on display 111. After determining that bar 10 is a used bar, controller 100 may notify the user of the reusable bar information via sound output unit 112. After determining that bar 10 is a used bar, controller 100 may transmit vibration to the user via tactile output unit 113.

[0144] The memory 120 can store preset pressure values. The memory 120 can be connected to the controller 100. The controller 100 can compare the preset pressure values ​​stored in the memory 120 with the pressure values ​​measured by the force sensor 72, and can determine whether the rod 10 is a used rod.

[0145] The reuse of rod 10 is undesirable because it degrades the quality of smoke and increases the risk of ignition. Therefore, a force sensor 72 can be used to improve the quality of smoke from the aerosol generating device 1 and prevent ignition due to the reuse of rod 10.

[0146] Figure 23 A series of processes are shown in which rod 10 is inserted into aerosol generating device 1 and then removed from aerosol generating device 1. Figure 24 A series of processes are shown in which the used rod 10' is inserted into the aerosol generating device 1 and then removed from the aerosol generating device 1.

[0147] refer to Figure 23 and Figure 24 The rod 10 can be inserted into the aerosol generating device 1. The opposite end 713 of the probe 71 can be inserted into the rod 10 inserted into the insertion space 46. The inserted rod 10 can press the probe 71. When the rod 10 presses the probe 71, the probe 71 can move in its longitudinal direction. The moved probe 71 can come into contact with the force sensor 72.

[0148] When rod 10 is inserted into aerosol generating device 1, probe 71 can be kept in contact with force sensor 72. Therefore, pressure values ​​can be continuously measured by force sensor 72. Controller 100 can determine that rod 10 has been inserted based on the pressure values ​​continuously measured by force sensor 72.

[0149] When the probe 71 is inserted into the rod 10, a hole 10” can be formed in one surface of the rod 10. For example, the hole 10” can be formed in the lower surface of the used rod 10’. The hole 10” can be located at the center of the cross section of the rod 10’. The hole 10” can have a shape corresponding to the outer surface of the opposite end 713 of the probe 71.

[0150] When the used rod 10' is reinserted into the aerosol generating device 1, the used rod 10' can press against the probe 71. During the insertion of the rod 10 or 10' into the aerosol generating device 1, the force applied by the new rod 10 to press against the probe 71 can be greater than the force applied by the used rod 10' to press against the probe 71. Since the hole 10" has already been formed in the used rod 10', the probe 71 can be smoothly inserted into the used rod 10'.

[0151] Therefore, the controller 100 can compare the pressure value measured during the insertion of the rod 10 with the preset pressure value, and can determine whether the rod 10 inserted into the aerosol generating device 1 is a used rod.
