The second gasket 44 may include a crimping portion 441 that is inserted between the flange 434 and the side surface 458 of the base 45, and an extension portion 442 that extends from the crimping portion 441 along the side surface 458 of the base 45 and is inserted between the base 45 and the first outer wall 411. This can prevent liquid in the container 413 from leaking between the lower housing 43 and the base 45 or between the base 45 and the upper housing 41.

The step 418 may be formed on the inner surface of the first outer wall 411. The step 418 may be molded with the flange 434. The step 418 may press the flange 434 of the second outer wall 431. The step 418 may press the second gasket 44. When the first outer wall 411 of the upper housing 41 is coupled to the base 45, the step 418 of the first outer wall 411 may press the flange 434 of the second outer wall 431 and the second gasket 44. Therefore, when the upper housing 41 and the base 45 are fastened, the second gasket 44 is compressed and the second gasket 44 may be in close contact with the first outer wall 411, the second outer wall 431 and the base 45.

The flange 434 may be formed by bending the end of the second outer wall 431 outwardly of the lower housing 43.

The crimping protrusion 410 may crimp the crimping portion 423 of the first gasket 42.

The crimping protrusion 410 may extend to surround the inner circumference of the crimping portion 423 of the first gasket 42. The crimping protrusion 410 extending along the first gasket 42 may be adjacent to the second inner wall 432. The crimping protrusion 410 extending along the first gasket 42 may contact the second inner wall 432. Therefore, it is possible to prevent the liquid in the container 413 from leaking into the liquid vaporization space 49.

The other end 713 of the long probe 71 may be inserted into the center of the stick 10. Therefore, the long probe 71 may move in the longitudinal direction of the long probe 71 by the length of the insertion of the stick 10, and the force of the stick 10 pushing the long probe 71 during the insertion process may be transmitted to the pressure sensor 72.

One end 714 of the long probe 71 may be adjacent to the second inner wall 432 of the lower housing 43. One end 714 and the other end 713 of the long probe 71 may be located on different axes when viewed in the longitudinal direction of the long probe 71.

The third part 717 may extend long in a direction intersecting the longitudinal direction of the long probe 71. For example, the third part 717 may extend long in a direction perpendicular to the longitudinal direction of the long probe 71.

On the other hand, the third part 717 may be located above the wick 47. This can prevent liquid or droplets falling from the wick 47 from leaking out of the cartridge 40 along the third part 717.

The locking rib 712 may protrude from the side of the long probe 71 in a direction intersecting the movement direction of the long probe 71. The locking rib 712 may be attached to the support 420 of the first inner wall 412. The locking rib 712 may extend long along the longitudinal direction of the long probe 71. The locking rib 712 may be located below the support 420. The locking rib 712 may be located between the upper housing 41 and the pressure sensor 72. The locking rib 712 may prevent the long probe 71 from moving more than a certain distance toward the insertion space 46.

The first seal 81 may include a thin film 811. The first seal 81 may contact the first inlet 451 of the base 45. The first seal 81 may extend along the periphery of the first inlet 451.

The first seal 81 may be inserted between the second outer wall 431 of the lower housing 43 and the first inlet 451. The first seal 81 may be made of an elastic material.

The first seal 81 can prevent liquid in the container 413 from leaking into the first inlet 451 through the gap between the lower housing 43 and the base 45. In addition, the first seal 81 seals the periphery of the first inlet 451, so that air pressure in the first inlet 451 can be maintained when the user inhales.

The thin film 811 may be disposed at the first inlet 451. The thin film 811 may be disposed on the flow path of the air drawn in from the first inlet 451. The thin film 811 may include a plurality of air holes. Therefore, the liquid cannot pass through the plurality of air holes, and therefore, the liquid can be prevented from leaking outside the cartridge 40.

The long 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 cartridge 40 along the long probe 71.

The support 420 may protrude inward from the first inner wall 412 of the upper housing 41. The support 420 may protrude toward the long probe 71. The support 420 may be located adjacent to the side of the long probe 71. The support 420 may support the side of the long probe 71 when the long probe 71 is tilted.

The depression 435 may be formed by the bottom surface 430 of the lower housing 43 being depressed into the lower housing 43. When the aerosol generating device 1 is turned over, droplets remaining between the lower housing 43 and the base 45 may accumulate in the depression 435. The depression 435 may prevent the droplets from leaking into the first inlet 451.

The holder 436 may be formed in the lower housing 43. The holder 436 may be formed in the second inner wall 432 of the lower housing 43. The holder 436 may be formed integrally with the lower housing 43. The holder 436 may include a hole 437 through which the long probe 71 slides. The holder 436 may allow the long probe 71 to pass through. The holder 436 may extend long in the longitudinal direction of the long probe 71. The hole 437 of the holder 436 may extend long in the longitudinal direction of the long probe 71. The hole 437 of the holder 436 may have a shape corresponding to the cross section of the long probe 71. The hole 437 may support the side of the long probe 71.

Meanwhile, the support 420 may be positioned above the locking rib 712 of the long probe 71. The support 420, the locking rib 712 and the holder 436 may be aligned in the longitudinal direction of the upper housing 41 in order. The support 420 may be positioned above the locking rib 712. The holder 436 may be positioned below the locking rib 712. Thus, when the long probe 71 moves along the longitudinal direction of the long probe 71, the support 420 and the holder 436 can limit excessive movement of the long probe 71.

Referring to FIG. 13, the second inner wall 432 of the lower housing 43 may include a notch 439. The first gasket 42 may include an extension portion 421, an insertion portion 422, and a crimping portion 423.

The notch 439 may be formed at one end of the second inner wall 432. The notch 439 may be formed by recessing in the longitudinal direction of the upper housing 41. That is, the notch 439 formed at the upper end of the second inner wall 432 may be recessed downward. The wick 47 may be inserted and seated in the notch 439. The notch 439 may have a shape corresponding to the outer shape of the wick 47. Therefore, the wick 47 is tightly fitted between the notch 439 and the insertion portion 422, thereby preventing leakage of liquid.

The first gasket 42 may include an extension portion 421 extending from the crimping portion 423 along the outer surface of the second inner wall 432 and inserted between the first inner wall 412 and the second inner wall 432, a crimping portion 423 inserted between the first inner wall 412 and the second inner wall 432, and an insertion portion 422 extending from the crimping portion 423 and inserted into the notch 439.

The extension portion 421 may extend from the crimping portion 423. The extension portion 421 may extend along the second inner wall 432 in the longitudinal direction of the second inner wall 432. The first inner wall 412 of the upper housing 41 may extend along the extension portion 421. The extension portion 421 may be inserted between the second inner wall 432 and the extended first inner wall 412.

The insert 422 can extend downward from the crimped portion 423 of the first gasket 42. The insert 422 can contact the wick 47 seated in the notch 439. The insert 422 can have a shape that corresponds to the outer shape of the wick 47. Thus, the insert 422 can be in close contact with the wick 47 to prevent liquid from leaking along the outer surface of the wick 47.

Referring to FIG. 14, the aerosol generating device 1 may include a first flow path 91, a second flow path 92, and a third flow path 93. The aerosol generating device 1 may also include a first gap 225, a second gap 520, a first through hole 521, an inhalation detection sensor 53, a second through hole 522, a first inlet 451, a second inlet 433, a battery 58, and a terminal 59.

The first flow path 91 can pass through the first gap 225 located between the insertion hole 21 of the cover 20 and the stick 10, and the second gap 520 formed between the upper casing 30 and the column 52. Air for generating aerosols can be inhaled through the first gap 225. The air inhaled into the insertion hole 21 can flow into the second gap 520 between the upper casing 30 and the column 52. The air inhaled into the second gap 520 can pass through the first through hole 521 formed in the column 52. That is, the first flow path 91 can sequentially connect the insertion hole 21, the second gap 520, and the first through hole 521.

The second flow path 92 may connect the first through hole 521 and the second through hole 522 formed in the column 52. The second flow path 92 may be located inside the column 52. The second flow path 92 may be connected to the first flow path 91.

The third flow passage 93 may be connected to the stick 10 inserted from the first inlet 451. As the third flow passage 93 passes around the wick 47, the liquid vaporized by the heater 48 may mix with the air. Thus, the user may inhale the aerosol through the stick 10.

The third flow passage 93 may be located between the bottom surface 430 of the lower housing 43 and the base 45. The third flow passage 93 may form a wide flow passage between the lower housing 43 and the base 45, ensuring a sufficient flow rate.

The battery 58 (see FIG. 22) may be mounted inside the body 50. The battery 58 may be located at the bottom of the body 50. The battery 58 may supply power to the heater 48. The battery 58 may supply power to the control unit 100. The battery 58 may supply power to the electronic devices included in the aerosol generating device 1. The battery 58 may supply power to the output unit 110, the pressure sensor 72, and the memory 120.

The terminal 59 may be connected to the battery 58. The terminal 59 may be connected to an external power source. The battery 58 may receive power from the outside via the terminal 59.

The first flow path 91 and the second flow path 92 will be described with reference to Figures 15 to 18.

A first gap 225 may be formed between the insertion hole 21 and the stick 10 inserted into the insertion hole 21. Air may pass through the first gap 225. The air that passes through the first gap 225 may flow into the inside of the column 52 through the second gap 520.

The second gap 520 may be formed between the upper casing 30 and the column 52. The second gap 520 may be formed around the column 52. One surface 32 of the upper casing 30, the top surface of the upper housing 41, and one surface 523 of the column 52, which form the second gap 520, may be formed flat. The second gap 520 may be connected to the first through hole 521. The second gap 520 may be formed by the spacing protrusion 31 of the upper casing 30.

The spacing protrusion 31 may form a second gap 520. The spacing protrusion 31 may be adjacent to the first through hole 521. The spacing protrusion 31 may protrude from the upper casing 30 facing the first through hole 521. The spacing protrusion 31 may contact the upper housing 41 or the column 52. The spacing protrusion 31 may space the upper casing 30 and the column 52. The spacing protrusion 31 may determine the width of the second gap 520.

The first through hole 521 may connect the first flow path 91 and the second flow path 92. The first through hole 521 may connect the second gap 520 and the inside of the column 52. The first through hole 521 may be formed on the outer surface of the column 52. The first through hole 521 may be formed on the upper surface of the column 52. The first through hole 521 may be adjacent to the upper housing 41 and the upper casing 30.

The inhalation detection sensor 53 can detect whether the user is inhaling. The inhalation detection sensor 53 can be provided on the first flow path 91, the second flow path 92, and the third flow path 93.

The inhalation detection sensor 53 may be provided on the second flow path 92. The inhalation detection sensor 53 may be spaced above the second through hole 522. The inhalation detection sensor 53 may be provided between the first through hole 521 and the second through hole 522. The inhalation detection sensor 53 may be located on the inner surface of the column 52 adjacent to the cartridge 40. Therefore, when the aerosol generating device 1 is tilted or rotated, it is possible to prevent failure of the inhalation detection sensor 53 that may occur due to penetration of liquid.

The inhalation detection sensor 53 can detect the flow of air. The inhalation detection sensor 53 can be a pressure sensor or an airflow sensor. The inhalation detection sensor 53 can be disposed adjacent to the first through hole 521 or the second through hole 522. The inhalation detection sensor 53 can detect the flow of air through the second flow path 92.

The second through hole 522 may connect the second flow path 92 and the third flow path 93. The second through hole 522 may be formed on one side of the column 52 facing the lower housing 43 or the base 45. The second through hole 522 may be located adjacent to the lower housing 43 or the base 45. The second through hole 522 may face the first inlet 451 of the base 45. The second through hole 522 may be connected to the first inlet 451 of the base 45. A sealing member (not shown) may be inserted between the second through hole 522 and the first inlet 451. The second through hole 522 may be tightly attached to the first inlet 451.

Meanwhile, the second inlet 433 may be arranged to be offset from the wick 47 in the longitudinal direction (or vertical direction) of the upper housing 41, and may be located on different axes. That is, the second inlet 433 may be separated from the wick 47 in the diameter direction of the second inlet 433. Therefore, the liquid that falls from the wick 47 does not immediately flow into the second inlet 433, so that it is possible to prevent the liquid from leaking outside the cartridge 40.

Meanwhile, the hole 437 of the holder 436 may be positioned offset from the wick 47 in the longitudinal direction (or vertical direction) of the upper housing 41 and positioned on different axes. That is, the hole 437 may be spaced apart from the wick 47 in the diametric direction of the hole 437. The wick 47 may be positioned between the hole 437 and the second inlet 433 in the diametric direction of the hole 437. Also, the hole 437 of the holder 436 and the second inlet 433 may be positioned symmetrically with respect to the wick 47. Therefore, the liquid that falls from the wick 47 does not immediately flow into the hole 437 of the holder 436, thereby preventing leakage.

Referring to Figures 19 and 20, the aerosol generating device 1 can include a first boss 452, a second boss 438, a wall 453, a first through hole 455, a second through hole 511, a pressure sensor 72, a second seal 82, a control unit 100, an output unit 110, and a memory 120.

The first through hole 455 may be formed in the base 45. The first through hole 455 may be formed in the bottom surface 457 of the base 45. One end 714 of the long probe 71 may pass through the first through hole 455. The first through hole 455 may be located below the holder 436. The first through hole 455 and the second through hole 511 may be arranged in the longitudinal direction of the long probe 71.

The second through hole 511 may be formed in the mount 51 of the body 50. One end 714 of the long probe 71 may pass through the second through hole 511. The second through hole 511 may be located below the first through hole 455. A part of the pressure sensor 72 may be located in the second through hole 511.

The pressure sensor 72 may be provided inside the body 50. The pressure sensor 72 may be located adjacent to one end 714 of the long probe 71. The pressure sensor 72 may be located below the long probe 71. The pressure sensor 72 may include a sensing portion 721 that contacts one end 714 of the long probe 71 when the long probe 71 moves from the insertion space 46 into the inside of the lower housing 43. The sensing portion 721 of the pressure sensor 72 may be pressed by one end 714 of the long probe 71.

The pressure sensor 72 can measure the pressure value generated when it comes into contact with the long probe 71. The pressure sensor 72 can send the measured pressure value to the control unit 100. The control unit 100 can store a preset pressure value, and the control unit 100 can compare the magnitude of the pressure value measured by the pressure sensor 72 with the magnitude of the preset pressure value.

One surface of the sensing part 721 that contacts one end 714 of the long probe 71 may be formed as a curved surface. For example, the sensing part 721 may include a curved surface formed to bulge toward the long probe 71. Therefore, even if the long probe 71 tilts during movement, the contact point between the one end 714 and the sensing part 721 can be formed at the center of the sensing part 721, and since the single contact point is formed, the accuracy of the pressure sensor 72 can be improved.

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 connecting the first support portion 821 and the second support portion 823, and a contact portion 824 that contacts the long probe 71.

The first support portion 821 may be supported by a first boss 452 protruding from the base 45. The lower surface of the first support portion 821 may be supported by the base 45, and the side surface of the first support portion 821 may be supported by the first boss 452. The first support portion 821 may be bonded to the base 45.

The second support portion 823 may contact the lower housing 43. The second support portion 823 may extend along the bottom surface 430 of the lower housing 43. The second support portion 823 may surround the hole 437 of the holder 436. The second support portion 823 and the contact portion 824 may seal the hole 437 of the holder 436, thereby preventing liquid from leaking outside the lower housing 43 through the hole 437 of the holder 436.

The first support portion 821 and the second support portion 823 can support the lower surface and the upper surface of the second seal 82, respectively. Therefore, even if the long probe 71 moves in the longitudinal direction of the long probe 71, the second seal 82 can maintain a fixed position in the longitudinal direction of the long probe 71.

The contact portion 824 may surround the outer surface of the long probe 71. The contact portion 824 may be disposed along the circumference of the long probe 71. The contact portion 824 may be bonded to the long probe 71. The contact portion 824 may extend in the longitudinal direction of the long probe 71. The contact portion 824 may prevent liquid that has leaked outside the lower housing 43 from leaking along the long probe 71 to the outside of the base 45.

Meanwhile, the aerosol generating device 1 may include a plurality of protrusions (not shown) protruding from the base 45 to support the side of the second seal 82. The plurality of protrusions may be arranged symmetrically around the long probe 71. The plurality of protrusions may be in the form of a boss formed integrally.

The first boss 452 may protrude from the base 45. The first boss 452 may protrude from the base 45 toward the lower housing 43. The first boss 452 may support a side surface of the second seal 82. The first boss 452 may support an outer surface of the first support portion 821. The first boss 452 may maintain a fixed position of the second seal 82 in a direction perpendicular to the longitudinal direction of the long probe 71.

The second boss 438 may protrude from the lower housing 43. The second boss 438 may protrude toward the base 45. The second boss 438 may surround the first boss 452. The second boss 438 may surround the outside of the first boss 452. The second boss 438 and the first boss 452 may overlap each other in a direction intersecting the longitudinal direction of the long probe 71. For example, the second boss 438 and the first boss 452 may overlap each other in a direction perpendicular to the longitudinal direction of the long probe 71. This can prevent liquid or droplets from penetrating from the outside of the second boss 438 to the inside of the first boss 452.

The 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 along the second flow path 92 to the first inlet 451.

Meanwhile, the wall 453 can bend along the second flow path 92 or in the opposite direction to the second flow path 92. The wall 453 can bend toward the second inlet 433 or the first inlet 451. Therefore, even if the aerosol generating device 1 is laid down or tilted, leakage into the first inlet 451 can be effectively prevented.

Figure 21 shows the case where the long probe 71 moves from the insertion space 46 to the outside of the lower housing 43 and one end 714 comes into contact with the sensing portion 721 of the pressure sensor 72.

When the stick 10 is inserted into the insertion space 46, the long probe 71 in contact with the stick 10 can move in the longitudinal direction of the long probe 71. The second seal 82 surrounding the long probe 71 can move in the direction of movement of the long probe 71 as the long probe 71 moves. Even if liquid or droplets leak out of the lower housing 43 along the long probe 71, the second seal 82 can prevent leakage out of the base 45.

When one end of the long probe 71 comes into contact with the sensing unit 721, the pressure value sensed by the pressure sensor 72 can be transmitted to the control unit 100. The control unit 100 can compare the sensed pressure value with the preset pressure value to determine whether the stick 10 has been used.

Referring to FIG. 22, the aerosol generating device 1 can include a control unit 100, an output unit 110, and a memory 120.

The control unit 100 can determine that the stick 10 has not been used if the pressure value measured by the sensing unit 721 is greater than a preset value. The control unit 100 can determine that the stick 10 has been used if the measured pressure value is less than the preset value. That is, the control unit 100 can determine whether the stick 10 inserted into the aerosol generating device 1 has been used based on the pressure value sensed by the pressure sensor 72.

The output unit 110 may include a display 111, an audio output unit 112, and a haptic output unit 113. The output unit 110 may be operated by the control unit 100. When the control unit 100 determines that the stick 10 has been used, the control unit 100 may output the fact that the stick 10 has been used to the display 111. When the control unit 100 determines that the stick 10 has been used, the control unit 100 may notify the user that the stick 10 has been reused through the audio output unit 112. When the control unit 100 determines that the stick 10 has been used, the control unit 100 may transmit vibrations to the user through the haptic output unit 113.

The memory 120 can store the preset pressure value. The memory 120 can be connected to the control unit 100. The control unit 100 can compare the preset pressure value stored in the memory 120 with the pressure value measured by the pressure sensor 72 to determine whether the stick 10 has been used.

Reusing the stick 10 must be prevented because it reduces smoking quality and increases the risk of the stick 10 catching fire. Therefore, the pressure sensor 72 can be used to improve the smoking quality of the aerosol generating device 1 and prevent ignition due to the reuse of the stick 10.

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

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

When the stick 10 is inserted into the aerosol generating device 1, the long probe 71 can maintain contact with the pressure sensor 72. Therefore, the pressure sensor 72 can continuously measure the pressure value. The control unit 100 can determine that the stick 10 has been inserted based on the pressure value being continuously measured by the pressure sensor 72.

When the long 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 underside of a 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 that corresponds to the outer surface of the other end 713 of the long probe 71.

When the used stick 10' is reinserted into the aerosol generating device 1, the used stick 10' can press the long 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 long probe 71 can be greater than the force with which the used stick 10' presses the long probe 71. Since a hole 10" is formed in the used stick 10', the long probe 71 can be smoothly inserted into the used stick 10'.

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