The first channel can communicate with the first inlet 301 and the first outlet 302. Air introduced through the first inlet 301 can be discharged from the first outlet 302 through the first channel. The first channel can be formed by connecting one of the multiple chambers in the second container 32 to the channel formed in the first container 301.

[0080] When the cartridge 30 is inserted into the receiving space 11, the cap 23 of the upper shell 20 can be positioned above the container head 33. The cap 23 can cover the upper part of the container head 33.

[0081] Therefore, it can prevent the smoke cartridge 30 from escaping outward from the receiving space 11.

[0082] The retaining protrusion 117 may be disposed at the lower part of the receiving space 11 and may protrude toward the interior of the receiving space 11. When the cartridge 30 is inserted into the receiving space 11, the retaining protrusion 117 may be fitted into the retaining groove 317 (see See Figure 2 ).

[0083] Therefore, when the second container 32 rotates in the receiving space 11, the first container can be kept in place without rotating with the second container 32.

[0084] A mounting groove 137 may be formed on the upper side of the receiving space 11. When the cartridge 30 is inserted into the receiving space 11, the mounting protrusion 337 may be fitted into the mounting groove 137 (see [reference]). Figure 5 ).

[0085] Therefore, when the cartridge 30 is inserted into the receiving space 11, the user can position the cartridge 30 in the correct position.

[0086] Therefore, when the second container 32 rotates in the receiving space 11, the container head 33 can be held in place without rotating with the second container 32.

[0089] The dial gear 42 can be rotated by rotating the dial 43. The dial gear 42 can be rotated by receiving power from a motor (not shown).

[0090] The dial gear 42 can rotate while engaging with the second container 32. The dial gear 42 can also rotate while directly engaging with the outer peripheral surface of the second container 32.

[0091] The cartridge gear 41 can be rotatably mounted in the housing 10. The cartridge gear 41 can be coaxially arranged with the second container 32.

[0092] The cartridge gear 41 can be configured to have a ring shape, with a space defined in its inner circumferential surface. The inner circumferential surface of the cartridge 41 can be configured to surround the receiving space 11. The inner circumferential surface of the cartridge gear 41 can engage with the outer circumferential surface of the second container 32 to rotate therewith. The dial gear 42 can engage with the outer circumferential surface of the cartridge gear 41 to rotate therewith.

[0093] The dial 43 may be mounted in the housing 10. At least a portion of the dial 43 may be exposed outside the housing 10. The dial 43 may be coaxially arranged with the dial gear 42. The dial 43 may rotate together with the dial gear 42 about the dial shaft 45. The dial shaft 45 may be arranged parallel to the container shaft 325.

[0094] Therefore, the user can rotate the second container 32 by rotating the dial 43 outside the housing 10.

[0095] Dial 43 can be mounted on the upper housing 13. Dial 43 can be mounted above the battery 50.

[0096] Therefore, users can easily rotate the dial 43 while holding the aerosol generating device.

[0097] Rotary switch 44 can be coaxially mounted with dial gear 42 and / or dial 43. Rotary switch 44 can be positioned above battery 50. Rotary switch 44 can detect the rotational position of dial gear 42 and / or dial 43, and therefore can detect the position of second container 32.

[0098] The controller 70 can use the rotary switch 44 to determine which of the plurality of granulation chambers the first connection channel 319 and the first outlet 302 are connected to.

[0099] The battery 50 may be disposed on the side surface of the receiving space 11. The battery 50 may be disposed parallel to the receiving space 11 and / or the cartridge 30. The battery 50 may be disposed adjacent to the dial gear 42 and the receiving space 11 in the longitudinal direction of the rotation axis of the dial gear 42.

[0100] Therefore, even when the volume of battery 50 is increased to increase its capacity, the aerosol generating device can have a compact structure suitable for the user's hand grip without unnecessarily increasing its length.

[0101] Therefore, space can be ensured above and below the battery 50 to accommodate the gear assembly 40, the mounting part 14, the flow sensor 60, the vibration motor, etc.

[0102] A flow sensor 60 may be disposed below the battery 50. The flow sensor 60 may be configured on a side surface facing the lower part of the receiving space 11. A sensing hole 61 may be formed between the flow sensor 60 and the receiving space 11. The flow sensor 60 can detect the airflow introduced into the cartridge 30 through the first inlet 301.

[0103] The mounting portion 14 may be formed in the upper housing 13 above the battery 50. The mounting portion 14 may be located above the dial gear 42 and the dial 43.

[0106] The controller 70 can be housed in the lower part of the housing 10. The controller 70 can be positioned below the receiving space 11. The controller 70 can be electrically connected to components such as the heater 314, rotary switch 44, battery 50, flow sensor 60, socket 80, vibration motor 90, etc. The controller 70 can control the operation of the components electrically connected to it.

[0107] The controller 70 controls the heater 314 to heat the core 313, thereby generating an aerosol. The controller 70 operates the flow sensor 60. The controller 70 can control the operation of internal components based on information corresponding to the detection results of the airflow. The controller 70 receives electrical signals from the rotary switch 44. The controller 70 can control the operation of components based on the electrical signals received from the rotary switch 44. The controller 70 can operate the vibration motor 90 to transmit vibration to the user.

[0108] Reference Figure 4 The first container 31 may include a cylinder 310 defining its appearance. A liquid chamber 311 may be formed in the cylinder 310. An evaporation channel 318 may be formed in the cylinder 310. The evaporation channel 318 may be formed in a vertically extending evaporation tube 3180. The evaporation tube 3180 may be surrounded by the liquid chamber 311.

[0109] An evaporator shell 3120 may extend downward from the evaporator tube 3180. The lower portion of the evaporator shell 3120 may expand radially outward to connect to the cylinder 310. An evaporator chamber 312 may be formed in the evaporator shell 3120. The evaporator chamber 312 may be connected vertically to the evaporator channel 318.

[0110] A core 313 may be disposed within an evaporator housing 3120. A heater 314 may be disposed within an evaporator housing 3120. The heater 314 may be wound around the core 313. The heater 314 may be configured to have a coil around the core 313. The heater 314 may include a coil. The heater 314 may be referred to as a coil heater 314. The coil of the heater 314 may be wound around the outer peripheral surface of the core 313.

[0111] A wick hole 3121 may be formed in the evaporation shell 3120 to connect the liquid chamber 311 to the evaporation chamber 312. A wick 313 may be inserted into the wick hole 3121. Pre-evaporated aerosol material may be introduced through the wick hole 3121 to wet the wick 313.

[0112] The cap 36 may define the bottom surface of the cartridge 30. The cap 36 may be disposed at the lower part of the first container 31. The cap 36 may cover the lower part of the cylinder 310. The outer surface of the cap 36 may be rounded upward to connect to the outer peripheral surface of the cylinder 310.

[0113] The first inlet 301 can be formed through the cap 36. The first inlet 301 can be connected to the evaporation chamber 312.

[0114] A first extension 362 may project upward from the bottom 361 of the cap 36 around the first entrance 301. The first extension 362 may extend upward from the bottom 361 of the cap 36 to surround the first entrance 301. The first extension 362 may define a step relative to the bottom 361 of the cap 36.

[0115] Therefore, it is possible to prevent pre-evaporated aerosol material leaking from the liquid chamber 311 from being discharged to the outside of the smoke cartridge 30 through the first inlet 301.

[0116] Connector 365 extends upward from the circumferential portion of cap 36. Connector 365 can be fitted into the inner circumferential surface of the lower part of cylinder 310.

[0117] Edge 367 may extend upward from connector 365. Edge 367 may be spaced inward from the inner circumferential surface of cylinder 310.

[0118] A lower sealant or lower seal 37 may be disposed between the cap 36 and the evaporation chamber 312. The lower seal 37 may be combined with the evaporation housing 3120 to define the evaporation chamber 312. The body 373 of the lower seal 37 may be disposed below the evaporation housing 3120. An evaporation inlet 371 may be formed vertically through the lower seal 37. The evaporation inlet 371 may be formed in the body 373 of the lower seal 37. The evaporation inlet 371 may be located between the first inlet 301 and the evaporation chamber 312, and may be connected to the first inlet 301 and the evaporation chamber 312.

[0119] The second extension 372 may extend upward from the lower seal 37. The second extension 372 may surround the evaporation inlet 371. The second extension 372 may protrude from the body 373 of the lower seal 37 surrounding the evaporation inlet 371. The second extension 372 may define a step relative to the bottom surface of the lower seal 37.

[0120] Therefore, downward leakage of the pre-evaporated aerosol material absorbed in the core 313 through the evaporation inlet 371 can be minimized. Pre-evaporated aerosol material leaking from the liquid chamber 311 can be prevented from being discharged to the outside of the cartridge 30 through the evaporation inlet 371 and the first inlet 301.

[0121] The upper edge 375 may extend upward from the outer periphery of the lower seal 37. The upper edge 375 may extend upward from the outer periphery of the body 373 of the lower seal 37. The rib 3122 may extend downward from the evaporator shell 3120. The upper edge 375 may be fitted between the rib 3122 and the inner periphery of the cylinder 310.

[0122] The lower edge 377 can extend downward from the outer peripheral portion of the lower seal 37. The lower edge 377 can be fitted between the edge 367 of the cap 36 and the inner peripheral surface of the cylinder 310.

[0123] The outer peripheral surfaces of the upper edge 375 and the lower edge 377 may define a continuous surface. The upper edge 375 and the lower edge 377 may contact the inner peripheral surface of the cylinder 310.

[0124] The following will refer to Figure 3 and Figure 4Describes the flow of air and aerosols when a user inhales air through mouthpiece 34.

[0125] When a user inhales air through the mouthpiece 34, air can be drawn in from the outside of the housing 10 and pass through the receiving space 11 between the housing 10 and the cartridge 30. Air that has passed through the receiving space 11 between the housing 10 and the cartridge 30 can be introduced into the evaporation chamber 312 in the first container 31 through the first inlet 301. The introduced air, along with the aerosol contained in the evaporation chamber 312, can pass through the evaporation channel 318. The aerosol that has passed through the evaporation channel 318 can be introduced into the second granulation chamber 322 sequentially through the first connecting channel 319 and the lower chamber orifice 323. The aerosol can sequentially pass through the medium in the second granulation chamber 322, the upper chamber orifice 324, and the first outlet 302. The aerosol that has passed through the first outlet 302 can be discharged upwards through the second inlet 341, the suction channel 343, and the second outlet 342.

[0126] Reference Figure 5 The second disc 327 can be connected to or fixed to the container shaft 325. The second disc 327 can be connected to or fixed to the rotating shaft 3251.

[0127] A connecting hole 3271 may be formed in the second disc 327. The connecting hole 3271 may be formed at the center of the second disc 327. A connecting member 3278 may extend through the connecting hole 3271. The connecting member 3278 may be fitted into the rotating shaft 3251. The connecting member 3278 may be threaded into the rotating shaft 3251. The connecting member 3278 may connect the second disc 327 to the container shaft 325.

[0128] A second disc hole 3279 may be formed in a second disc 327. The second disc hole 3279 may be formed at a position spaced apart from the center of the second disc 327. The second disc hole 3279 may be connected to (or communicate with) an upper chamber hole 324. The second disc hole 3279 may be connected to or communicate with an upper chamber hole 324 formed in the upper part of one of the plurality of granulation chambers 321 and 322. One of the plurality of granulation chambers 321 and 322 may communicate with a connecting channel via the upper chamber hole 324 and the second disc hole 3279.

[0129] A second connecting channel 329 may be formed between the second plate 327 and the container head 33.

[0130] The container head 33 can be connected to or attached to the second tray 327. The container head 33 can be fixed to the second tray 327.

[0131] A first outlet 302 may be formed in the container head 33. The first outlet 302 may communicate with the second connecting channel 329.

[0132] Reference Figure 5 and Figure 6The cartridge gear 41 may include an inner peripheral protrusion 416 fitted into the second guide slit 326. The inner peripheral protrusion 416 may project inwardly from the inner peripheral surface of the cartridge gear 41. The inner peripheral protrusion 416 may fit into the second guide slit 326. The inner peripheral protrusion 416 may engage with the second guide slit 326. The engagement of the inner peripheral protrusion 416 with the second guide slit 326 causes the cartridge gear 41 to rotate together with the second container 32.

[0133] The second guide slit 326 extends longitudinally along the axis of rotation of the second container 32. The second guide slit 326 guides the cartridge 30 vertically along the inner circumferential protrusion 416. When the cartridge 30 is inserted into the receiving space 11, the inner circumferential protrusion 416 engages at the upper end of the second guide slit 326. The upper end of the second guide slit 326 serves as a stop configured to prevent further downward movement of the cartridge 30.

[0134] The first guide slit 316 may extend in the longitudinal direction of the second guide slit 326. The first guide slit 316 and the second guide slit 326 may define a continuous surface such that the smoke cartridge 30 is guided perpendicularly along the inner peripheral protrusion 416.

[0135] The mouthpiece 34 can be pivotally connected or coupled to the container head 33. Figure 5 The cigarette holder 34 is shown in the state where it is pivoted to the first position. Figure 6 This shows the mouthpiece 34 pivoted in the second position.

[0136] The following will refer to Figure 5 Describes the state in which the mouthpiece 34 pivots to the first position.

[0137] When the mouthpiece 34 is pivoted to the first position, it can be positioned in the housing portion 14 to close the upper part of the housing 10. The mouthpiece 34 can close the opening O in the upper housing 20. One surface of the mouthpiece 34 can be exposed through the opening O.

[0138] The suction channel 343 in the mouthpiece 34 can be disposed in the upper housing 20. The suction channel 343 can be oriented so as not to be aligned with the longitudinal direction of the cartridge 30.

[0139] A sealing cap 35 may protrude downward from the mouthpiece 34. The sealing cap 35 may be configured to have a hook shape. The sealing cap 35 may close the first outlet 302.

[0140] Therefore, it can protect the media and pre-evaporated aerosol materials contained in the cartridges and internal components from the influence of the external environment.

[0141] The sealing cap 35 may have a rounded outer surface in the direction of pivoting of the mouthpiece 34. Therefore, when the mouthpiece 34 is pivoted to the first position, the sealing cap 35 will not get stuck on the surface surrounding the first outlet 302.

[0142] Next, we will refer to Figure 6 Describes the state in which the mouthpiece 34 pivots to the second position.

[0143] When the mouthpiece 34 is pivoted to the second position, the mouthpiece 34 can be separated from the housing portion 14. The sealing cap 35 can be separated from the first outlet 302 to open the first outlet 302.

[0144] The first outlet 302 can contact the second inlet 341. The suction channel 343 in the mouthpiece 34 can communicate with the first outlet 302. The suction channel 343 in the mouthpiece 34 can communicate with the space in the first container 31 and the space in the second container 32 through the first outlet 302.

[0145] The suction channel 343 can be oriented to extend in the longitudinal direction of the cartridge 30. The suction channel 343 can also be oriented to extend vertically. The sealing cap 35 can be oriented to protrude toward the placement portion 14.

[0146] The following is based on Figures 7 to 9 The orientation of the mouthpiece 34 is defined using an orthogonal coordinate system. In this system, the forward direction FD can be defined as the forward direction of the mouthpiece 34. The backward direction RD can be defined as the backward direction of the mouthpiece 34. The lateral direction LD can be defined as the right and left directions or the lateral direction of the mouthpiece 34. The upward direction UD can be defined as the upward direction of the mouthpiece 34. The downward direction DD can be defined as the downward direction of the mouthpiece 34.

[0147] Reference Figure 7 and Figure 8 The mouthpiece 34 can be configured to extend in both forward and rearward directions. The mouthpiece 34 can be configured to have a flat shape. A second inlet (or inlet port) 341 can be formed at the rear of the mouthpiece 34. A second outlet 342 can be formed at the front of the mouthpiece 34.

[0148] Suction channel 343 (see Figure 6 A second inlet 341 may be formed in the mouthpiece 343 and may extend in both forward and backward directions. A second outlet 342 may be located at one end of the suction channel 343. The distance between the pivot 355 and the second outlet 342 may be greater than the distance between the pivot 355 and the second inlet 341. The suction channel 343 may be referred to as the second channel 343.

[0149] Therefore, the user is able to inhale air while keeping part of the second outlet 342 in his / her mouth.

[0150] The retaining groove 347 may be formed as a recess in the side surface of the mouthpiece 34. The retaining groove 347 may include two retaining grooves formed in the two side surfaces of the mouthpiece 34. The retaining groove 347 may be closer to the second outlet 342 than to the second inlet 341.

[0151] The mouthpiece 34 may include a sealing cap 35. The sealing cap 35 may protrude outward from the mouthpiece 34. The sealing cap 35 may protrude downward from the mouthpiece 34. The sealing cap 35 may be integrally formed with the mouthpiece 34. The sealing cap 35 may be attached to the mouthpiece 34. The sealing cap 35 may be positioned closer to the second inlet 341 than to the second outlet 342.

[0152] The mouthpiece 34 is pivotable about a pivot 355. The pivot 355 can be considered the center of the pivoting action or pivot point of the mouthpiece 34. The pivot 355 can protrude from both side surfaces of the mouthpiece 34 or the sealing cap 35 in the right and left directions. The pivot 355 can be positioned perpendicular to the vertical direction. The pivot 355 can be closer to the second inlet 341 than to the second outlet 342.

[0153] The sealing cap 35 may include an extension 352 extending downward from the mouthpiece 34. The sealing cap 35 may include a first sealing surface 356 extending rearwardly from the lower end of the extension 352 in the mouthpiece 34. The first sealing surface 356 may define an outer surface of the lower end of the sealing cap 35.

[0154] When the mouthpiece 34 pivots, the first sealing surface 356 can contact the area surrounding the first outlet 302. When the mouthpiece 34 is in the first position, the first sealing surface 356 is positioned above the first outlet 302 to close the first outlet 302 (see [link]). Figure 5 When the mouthpiece 34 is in the first position, the first sealing surface 356 can contact the gasket 331 disposed around the first outlet 302 (see...). Figure 11 Close contact. Alternatively, gasket 331 may be referred to as a mating member or mating ring.

[0155] The first sealing surface 356 may include a portion that extends in a rounded manner in the direction of pivoting of the mouthpiece 34. The first sealing surface 356 may include a first planar portion 356a formed having a planar surface and a first circular portion 356b that is rounded in the direction of pivoting of the mouthpiece 34.

[0156] The first planar portion 356a may define the lower surface of the extension 352. The first circular portion 356b may define a surface that extends from the first planar portion 356a toward the second inlet 341 while being rounded. The first circular portion 356b may have a radius of curvature, the center of which is adjacent to the pivot center of the mouthpiece 34.

[0157] Therefore, when the mouthpiece 34 pivots, it can pivot smoothly between a first position and a second position without the first sealing surface 356 of the sealing cap 35 being engaged with the surface surrounding the first outlet 302. The end of the sealing surface 356 and / or the sealing cap 35 may be spaced apart from the lower surface of the mouthpiece 34 to define a space S between the mouthpiece 34 and the end. The front and lower sides of the space S may be surrounded by the extension 352 and the first sealing surface 356. The extension 352 of the sealing cap 35 and the first sealing surface 346 may define a hook-shaped cross-section.

[0158] The sealing cap 35 may be made of an elastic material. For example, the sealing cap 35 may be made of a plastic material.

[0159] Therefore, when the mouthpiece 34 is in the first position, the first sealing surface 356 can contact the first outlet 302, and the first outlet 302 can be pressed while being pushed toward the space S.

[0160] The mouthpiece 34 may include a second sealing surface 346, which forms the rear surface of the mouthpiece 34 and surrounds the second inlet 341. The second sealing surface 346 may define the outer surface of the mouthpiece 34 around the second inlet 341.

[0161] When the mouthpiece 34 pivots, the second sealing surface 346 can contact the area surrounding the first outlet 302. When the mouthpiece 34 is in the second position, the second sealing surface 346 can be configured to surround the first outlet 302, and the second inlet 341 can communicate with the first outlet 302 (see [reference]). Figure 6 When the mouthpiece 34 is in the second position, the second sealing surface 346 can contact the gasket 331 disposed around the first outlet 302 (see...). Figure 11 (Close contact)

[0162] The second sealing surface 346 may include a portion that extends in a rounded manner in the direction of pivoting of the mouthpiece 34. The second sealing surface 346 may include a second planar portion 346b formed having a planar surface and a second circular portion 346a that is rounded in the direction of pivoting of the mouthpiece 34. The second planar portion 346b may be formed to be higher than the second circular portion 346a.

[0163] The second circular portion 346a may form a surface that extends while being rounded in the direction of pivoting of the mouthpiece 34. The second circular portion 346a may have a predetermined curvature. The center of curvature of the second circular portion 346a may be adjacent to the pivoting center of the mouthpiece 34. The second planar portion 346b may extend from the second circular portion 346a in the upward direction of the mouthpiece 34 to define a planar surface.

[0164] Therefore, when the mouthpiece 34 pivots, the second sealing surface 346 of the mouthpiece 34 can pivot smoothly between the first position and the second position without getting stuck on the surface around the first outlet 302.

[0165] Spring 344 can be connected to mouthpiece 34. Spring 344 can be exposed to the outside of mouthpiece 34 through slit 354 formed in sealing cap 35. A portion of spring 344 can be exposed downward from mouthpiece 34.

[0166] Reference Figure 9 The sealing cap 35 may include inwardly projecting assembly protrusions 359.

The assembly grooves 359 may include two assembly grooves formed on two side surfaces of the mouthpiece 34. The assembly protrusions 359 may be fitted into the assembly grooves 349. The sealing cap 35 may be assembled with the mouthpiece 34 to project downward from the mouthpiece 34.

[0167] The mouthpiece 34 may include a spring-loaded connecting shaft 345 projecting outward from its side surface. The spring-loaded connecting shaft 345 may be formed coaxially with a pivot 355. A spring 344 may be wound around the spring-loaded connecting shaft 345 to extend in the longitudinal direction of the spring-loaded connecting shaft 345. One end of the spring 344 may contact the mouthpiece 34, and the other end of the spring 344 may be exposed from the mouthpiece 34.

[0168] Reference Figure 10 and Figure 11 The mouthpiece 34 can be pivotally connected or coupled to the container head 33. A shaft hole 335 can be formed in both side surfaces of the container head 33. A pivot 355 can be fitted into the shaft hole 335. The mouthpiece 34 can pivot about the pivot 355 fitted into the shaft hole 335.

[0169] The container head 33 can be configured to have a cylindrical form extending upward from the outer peripheral surface of the second container 32. A shaft hole 335 can be formed in two side surfaces of the upper portion of the container head 33. The container head 33 can be open at its upper surface, allowing a mouthpiece 34 to be disposed within it. A portion of one side surface of the container head 33 can be open. The container head 33 can be configured such that its upper surface portion and side surface portion are continuously open to have an "L" shape. The mouthpiece 34 can pivot in the open area of ​​the container head 33.

[0170] A first outlet 302 may be formed in the bottom surface of the container head 33. The first outlet 302 may be connected to a connecting channel 329 formed in the upper part of the second container 32. Aerosol generated from the cartridge 30 may be discharged from the first outlet 302 through the connecting channel 329.

The gasket 331 may have a shape corresponding to the circumference of the second inlet 341 to surround the second inlet 341. The gasket 331 may be made of an elastic material such as rubber or silicone.

[0172] When the mouthpiece 34 is in the first position, the gasket 331 can be in close contact with the first sealing surface 356 of the sealing cap 35. When the mouthpiece 34 is in the second position, the gasket 331 can be in contact with the second sealing surface 346 surrounding the second inlet 341 that forms the rear surface of the mouthpiece 34.

[0183] An inner circumferential protrusion 416 may protrude from the inner circumferential surface of the cartridge gear 41 toward the receiving space. The inner circumferential protrusion 416 may include a plurality of inner circumferential protrusions 416. The plurality of inner circumferential protrusions 416 may be arranged in a circumferential direction. The plurality of inner circumferential protrusions 416 may be arranged in a circumferential direction about an axis (an imaginary vertically extending line) of the receiving space 11. The plurality of inner circumferential protrusions 416 may be arranged in a circumferential direction about a rotation axis of the cartridge gear 41.

The inner peripheral protrusion 416 may extend in the longitudinal direction of the first guide slit 316. The inner peripheral protrusion 416 may extend in the longitudinal direction of the second guide slit 326.

[0186] The receiving space 11 may be open on one of its surfaces. The receiving space 11 may be open on its upper side.

[0187] The gear mounting hole 411 may be open on its surface facing the open surface of the receiving space 11. The gear mounting hole 411 may also be open on its surface opposite to one of the open surfaces. One surface and the other surface of the gear mounting hole 411 may be open. The gear mounting hole 411 may be open on the side where the cartridge 30 is inserted. The gear mounting hole 411 may be open on the side where the cartridge 30 is removed. The gear mounting hole 411 may be open on both its upper and lower sides.

[0188] The inner peripheral protrusion 416 may include inclined surfaces 416a and 416b. The length of the inner peripheral protrusion 416 at its outer side may be greater than its length at its inner side. The inner peripheral protrusion 416 may be configured to have a trapezoidal shape.

[0189] Inclined surfaces 416a and 416b may be located at both ends of the inner peripheral protrusion 416 in its longitudinal direction. Inclined surfaces 416a and 416b may include a first inclined surface 416a and a second inclined surface 416b respectively located at both ends of the inner peripheral protrusion 416 in the longitudinal direction.

[0190] The first inclined surface 416a may be located at one end of the inner peripheral protrusion 416 in the longitudinal direction. The first inclined surface 416a may be located at the end of the open surface of the inner peripheral protrusion 416 where the receiving space 11 is provided. The first inclined surface 416a may be located at the end of the surface of the inner peripheral protrusion 416 where the gear mounting hole 411 is provided. The first inclined surface 416a may be located at the upper part of the inner peripheral protrusion 416.

[0191] The second inclined surface 416b may be located at the other end of the inner peripheral protrusion 416 in the longitudinal direction. The second inclined surface 416b may be located at the other end of the inner peripheral protrusion 416 where the open surface of the receiving space 11 is provided. The second inclined surface 416b may be located at the other end of the inner peripheral protrusion 416 where the gear mounting hole 411 is provided (opposite to one surface). The second inclined surface 416b may be located at the lower part of the inner peripheral protrusion 416.

[0192] The first inclined surface 416a may face the open surface of the receiving space 11. The first inclined surface 416a may face both the open surface of the receiving space 11 and the central axis of the receiving space 11. The first inclined surface 416a may be inclined toward the central axis of the receiving space 11 while moving in the direction in which the tobacco cartridge 30 is inserted into the receiving space 11. The first inclined surface 416a may be inclined toward the central axis of the receiving space 11 while moving downward.

[0193] The first inclined surface 416a may face the open surface of the gear mounting hole 411. The first inclined surface 416a may face both the open surface of the gear mounting hole 411 and the central axis of the gear mounting hole 411. The first inclined surface 416a may tilt towards the central axis of the gear mounting hole 411 while moving in the direction in which the cartridge 30 is inserted into the gear mounting hole 411. The first inclined surface 416a may tilt towards the central axis of the gear mounting hole 411 while moving downwards.

[0194] The upper end of the second guide slit 326 may face the first inclined surface 416a (see...). Figure 5 The upper end of the second guide slit 326 may be tilted to be parallel to the first inclined surface 416a (see...). Figure 5 ).

[0195] The second inclined surface 416b may face a direction opposite to that of the open surface of the receiving space 11. The second inclined surface 416b may face a direction opposite to that of the open surface of the receiving space 11, and may face the central axis of the receiving space 11. The second inclined surface 416b may tilt towards the central axis of the receiving space 11 while moving in the direction in which the tobacco cartridge 30 is removed from the receiving space 11. The second inclined surface 416b may tilt towards the central axis of the receiving space 11 while moving upwards.

The second inclined surface 416b may tilt towards the central axis of the receiving space 11 while moving upwards.

[0197] Therefore, the smoke cartridge 30 can be easily inserted into the receiving space 11.

[0198] Therefore, the smoke cartridge 30 can be easily removed from the receiving space 11.

[0199] Therefore, the tobacco cartridge 30 can be easily inserted into the gear assembly hole 411.

[0200] Therefore, the cartridge 30 can be easily removed from the gear assembly hole 411.

[0201] Therefore, even when the first guide slit 316 and the inner peripheral protrusion 416 are not aligned with each other, the smoke cartridge 30 can be easily inserted into the receiving space 11.

[0202] Therefore, even when the first guide slit 316 and the second guide slit 326 are not aligned with each other, the smoke cartridge 40 can be easily inserted and removed.

[0203] Reference Figures 14 to 16 The cartridge 30 can be fitted into the gear mounting hole 411 formed in the cartridge gear 41. The cartridge 30 can be fitted in the direction of the rotation axis of the cartridge gear 41. The direction of the rotation axis of the cartridge gear 41 can be vertical.

[0204] The inner peripheral protrusion 416 can be fitted into the first guide slit 316 and the second guide slit 326. The inner peripheral protrusion 416 can guide the smoke cartridge 30 into the receiving space 11 by sliding along the first guide slit 316 and the second guide slit 326. The first guide slit 316 and the second guide slit 326 can contact the inner peripheral protrusion 416 in sequence.

[0205] The first guide slit 316 may include a plurality of first guide slits arranged in the circumferential direction of the cartridge 30. The second guide slit 326 may include a plurality of second guide slits arranged in the circumferential direction of the cartridge 30. The inner circumferential protrusion 416 may include a plurality of inner circumferential protrusions arranged in the circumferential direction of the cartridge 41. The plurality of inner circumferential protrusions 416 may be arranged at positions corresponding to the plurality of second guide slits 326. Each of the plurality of inner circumferential protrusions 416 may be fitted into a corresponding one of the plurality of second guide slits 326.

[0206] The circumferential direction of the cartridge 30 can be the same as the rotation direction of the second container 32. The circumferential direction of the cartridge gear 41 can be the same as the rotation direction of the cartridge gear 41. The rotation direction of the second container 32 can be the same as the rotation direction of the cartridge gear 41.

[0207] When the smoke cartridge 30 is fully assembled into the receiving space 11, the protrusion 117 remains (see Figure 12 The cartridge 30 can be fitted into the retaining recess 317, thereby holding the first container 31 in place. When the cartridge 30 is fully fitted into the receiving space 11, the fitting protrusion 337 can be fitted into the fitting recess 137 (see...). Figure 6This holds the container head 33 in place. When the cartridge 30 is fully assembled into the receiving space 11, the inner circumferential protrusion 416 may be located at the upper end of the second guide slit 326.

[0208] Therefore, when the cartridge gear 41 rotates, the second container 32 can rotate because the inner circumferential protrusion 416 engages with the second guide slit 326. The rotation of the second container 32 maintains the position of the first container 31. The rotation of the second container 32 also maintains the positions of the container head 33 and the mouthpiece 34.

[0209] The second guide slit 326 may include a portion that widens as it moves downwards. The second guide slit 326 may have its maximum width at the lower end of the second container 32. The width w2 of the second guide slit 326 may continuously decrease as it moves upwards from the lower end, and may maintain a constant value w1 from a predetermined height to its upper end. The width w2 of the lower portion of the second guide slit 326 may be greater than the width w1 of the upper portion of the second guide slit 326.

[0210] The width w3 of the first guide slit 316 may become equal to the width w2 of the lower end of the second guide slit 326 at the portion where it abuts the lower end. The width w3 of the first guide slit 316 may be equal to or greater than the width w1 of the upper portion of the second guide slit 326.

[0211] The second guide slit 326 may have a portion with the same width as the inner peripheral protrusion 416. The upper width w1 of the second guide slit 326 may be equal to the width w0 of the inner peripheral protrusion 416 (see...). Figure 13 The width w2 of the lower part of the second guide slit 326 may be greater than the width w0 of the inner peripheral protrusion 416. The width w3 of the first guide slit 316 may be greater than the width w0 of the inner peripheral protrusion 416.

[0212] Therefore, even when the first guide slit 316 and the second guide slit 326 are not aligned, when the cartridge 30 is assembled into the gear assembly hole 411, the inner circumferential protrusion 416 slides along the side surfaces of the first guide slit 316 and the second guide slit 326, thereby aligning the first guide slit 316 and the second guide slit 326.

[0213] Therefore, since the first connection channel 319 is precisely connected to the lower chamber orifice 323, the reduction in aerosol flow efficiency can be prevented.

[0214] Reference Figure 16 and Figure 17 The cartridge gear 41 can mesh with the dial gear 42 to rotate with it. The rotation axis of the cartridge 41 and the rotation axis of the dial gear 42 can be parallel to each other.

[0215] A first gear tooth 412 may be formed on the outer peripheral surface of the cartridge gear 41. A second gear tooth 422 may be formed on the outer peripheral surface of the dial gear 42. The first gear tooth 412 and the second gear tooth 422 may mesh with each other to rotate together. The height of the first gear tooth 412 may be equal to the height of the second gear tooth 422.

[0216] The dial 43 can be connected to the dial gear 42 to rotate with it. The dial 43 and the dial gear 42 can be arranged coaxially.

[0217] An irregular portion 432 may be formed on the outer peripheral surface of the dial 43. The height of the irregular portion 432 may be lower than the height of the first gear tooth 412 and the height of the second gear tooth 412.

[0218] The user can rotate the dial 43 from the outside of the housing 10 (see Figure 1 When the dial 43 is rotated by the user, the dial gear 42 and the cartridge gear 41 rotate in sequence, thereby causing the second container 32 to rotate.

[0219] Reference Figure 15 and Figure 18 The cap 36 can form the bottom surface of the smoke cartridge 30. The cap 36 can be referred to as the plug 36. The cap 36 can also be referred to as the lower cap 36. The cap 36 can be positioned below the cylinder 310 (see...). Figure 4 The cap 36 can be attached to or joined to the cylinder 310. The cap 36 can be fixed to the cylinder 310. A mounting hole 307 can be formed in the cap 36 by making the lower surface of the cap 36 recessed upward. The mounting hole 307 can be positioned spaced apart from the center of the cap 36. The mounting hole 307 can be spaced apart from a line extending from the rotation axis of the second container 32. Hereinafter, the mounting hole 307 may be referred to as the mounting hole 307.

[0220] The base 16 may be configured to surround the lower portion of the receiving space 11. A mounting protrusion 167 may project upward from the bottom surface 168 of the base 16. The mounting protrusion 167 may be spaced apart from the center of the base 16. The mounting protrusion 167 may be spaced apart from a line extending from the rotation axis of the second container 32.

[0221] The mounting hole 307 can be located at a position corresponding to the mounting protrusion 167. When the cartridge 30 is assembled into the receiving space 11, the mounting protrusion 167 can be assembled into the mounting hole 307.

[0222] The mounting protrusion 167 can be configured to have an upwardly extending cylindrical shape. The upper part of the mounting protrusion 167 can narrow as it moves upward. The upper end of the mounting protrusion 167 can be rounded.

[0223] Therefore, the first container 31 and the cartridge 30 can be positioned at a designated location.

[0224] Therefore, even if the mounting protrusion 167 is not precisely aligned with the mounting hole 307, the upper end of the mounting protrusion 167 can be guided into the mounting hole 307, thereby guiding the cartridge to the correct position.

[0225] Therefore, the first container 31 can remain in place even when the second container 32 rotates.

[0226] A first terminal 164 may protrude upward from the bottom surface 168 of the base 16. The first terminal 164 may consist of a pair of terminals and may be spaced equidistant from the center of the base 16. The first terminal 164 may be configured to have an upwardly extending cylindrical form. The first terminal 164 may receive power from the battery 50.

[0227] A second terminal 304 may be formed on the bottom surface of the cap 36. The second terminal 304 may consist of a pair of terminals and may be spaced equidistant from the center of the cap 36. The second terminal 304 may be electrically connected to the heater 314.

[0228] The second terminal 304 may be located at a position corresponding to the first terminal 164. When the cartridge 30 is assembled into the receiving space 11, the second terminal 304 may contact the first terminal 164 and thus be electrically connected to it. The first terminal 164 may transmit power to the second terminal 304, causing the heater 314 to heat the core 313.

[0229] Reference Figure 19 Combination Figure 2 The connector 110 may include a cylindrical connector body 111. The connector body 111 may extend vertically.

[0230] The connector 110 may have a structure configured to retain the rotatable position of the cartridge 30. A retaining protrusion 117 may protrude from the inner peripheral surface 112 of the connector 110.

[0233] Retaining protrusions 117 and 119 may protrude from necks 116 and 118 toward the interior of connector 110, respectively. Hereinafter, retaining protrusions 117 and 119 may be referred to as heads 117 and 119. Heads 117 and 119 may be fitted into retaining recesses 317.

[0234] Heads 117 and 119 hold the first container 31 in place. When the cartridge 30 is fitted into the receiving space 11, heads 117 and 119 hold the first container 31 in place. Because heads 117 and 119 fit into the retaining groove 317, the first container 31 cannot rotate even when the second container 32 rotates.

[0235] A groove 114 may be formed on the lower part of the connector 110. A lower groove 114 may be formed on the lower end of the connector 110.

The number of connecting protrusions 3253P may correspond to the number of connecting grooves 383 in the connecting disc 38. When the connecting disc 38 is assembled into the second container 32, the connecting protrusion 3253P may be assembled into the connecting grooves 383. The second pipe portion 384b of the pipe 384 may be assembled into the disc hole 3259 in the first disc 3253. Gas flowing through the evaporation channel 318 may flow to the second container 32 via the first pipe portion 384a and the second pipe portion 384b.

[0255] Reference Figures 27 to 29 The second container 32 may include multiple chambers 321 and 322. The multiple chambers 321 and 322 may be divided into a first chamber 321a, a second chamber 321b, a third chamber 322a, and a fourth chamber 322b. A rotation shaft 325 may extend between the multiple chambers 321 and 322.

[0264] The following will describe a smoke cartridge according to another embodiment of the present disclosure. Here, reference is made to the above. Figures 1 to 32 Descriptions that are identical to those described will be omitted.

[0265] Reference Figure 33 The cartridge 300 can be fitted into the receiving space 11 defined in the outer casing 10. Aerosol can be generated in the cartridge 300 and can be emitted to the outside through the interior of the cartridge 300.

[0266] The cartridge 300 may be disposed in the receiving space 11. The cartridge 300 may include a first container 39 and a second container 32. The first container 39 may have a chamber configured to contain liquid.

[0267] The second container 32 may be connected to or coupled to the first container 39. The second container 32 may be positioned above the first container 39.

[0268] The second container 32 may be rotatably connected to or coupled to the first container 39. The second container 32 may be positioned above the first container 39. The first container 39 and the second container 32 may have approximately the same diameter.

[0269] A first guide slit 3916 may be formed in the outer peripheral surface of the first container 39. The first guide slit 3916 may be recessed inward from the outer peripheral surface of the first container 39. The first guide slit 3916 may be formed to extend vertically. The first guide slit 3916 may extend from the upper end to the lower end of the outer peripheral surface of the first container 39. Hereinafter, the first guide slit 3916 may be referred to as the first guide rail 3916.

[0270] When the second container 32 is rotated to a predetermined position, the second guide slit 326 can be aligned with the first guide slit 3916. In this position, the lower end of the second guide slit 326 can be connected to the upper end of the first guide slit 3916.

[0271] The width of the lower end of the second guide slit 326 may be the same as the width of the upper end of the first guide slit 3916. The first guide slit 3916 may be widest at its lower end and / or upper end.

[0272] The first guide slit 3916 may include a plurality of first guide slits arranged along the circumference of the first container 39.

[0273] The first guide slit 3916 may be referred to as a guide rail, guide channel, or guide groove.

[0274] A retaining groove 3917 may be formed in the outer peripheral surface of the first container 39. The retaining groove 3917 may be recessed inward from the outer peripheral surface of the first container 31. The retaining groove 3917 may be formed at a position spaced apart from the first guide slit 3916. The retaining groove 3917 may be formed at a position spaced outward from the first guide slit 3916. A retaining protrusion 117 (see below) is provided in the lower part of the receiving space 11. Figure 3 It can be fitted into the retaining groove 3917 (see...) Figure 3 )middle.

[0275] The groove 3917 can be kept in the cylinder 391 (see...) Figure 35 It extends in the circumferential direction. The length of the retaining groove 3917 may be greater than its width. The retaining protrusion 117 may have a length and width corresponding to the retaining groove 3917.

[0276] The retaining groove 3917 may include multiple retaining grooves. The retaining groove 3917 may include a first retaining groove 3917 located at a lower level and a second retaining groove 3917 located at a higher level. The second retaining groove 3917 may be positioned closer to the second container 32 than the first retaining groove 3917. The first retaining groove 3917 and the second retaining groove 3917 may be positioned at locations spaced apart from each other in the circumferential direction.

[0277] The first retaining groove 3917 may include a plurality of first retaining grooves. The second retaining groove 3917 may include a plurality of second retaining grooves.

[0278] Alternatively, a retaining protrusion may be formed on the outer peripheral surface of the first container 39, and a retaining groove may be formed in the lower part of the receiving space 11. The retaining protrusion formed on the outer peripheral surface of the first container 39 can be fitted into the retaining groove in the lower part of the receiving space 11.

[0279] Hereinafter, the retaining groove or retaining protrusion 3917 formed on the outer peripheral surface of the first container 39 may be referred to as the first rotation limiter 3917, and the retaining protrusion or retaining groove 117 formed in the lower part of the receiving space 11 may be referred to as the second rotation limiter 117.

[0280] Head 117 and 119 (see Head 117 and 119) Figure 19The first container 39 can be held in place. When the cartridge 300 is assembled into the receiving space 11, the heads 117 and 119 can hold the first container 39 in place. Even when the second container 32 is rotated, the first container 39 cannot be rotated because the heads 117 and 119 are assembled into the retaining groove 3917.

[0281] The first head 117 may be disposed at a position corresponding to a lower level retaining groove 3917 among the plurality of retaining grooves 3917 formed in the first container 39. The second head 119 may be disposed at a position corresponding to a higher level retaining groove 3917 among the plurality of retaining grooves 3917 formed in the first container 39.

[0282] The smoke cartridge 300 can be vertically fitted into the receiving space 11 in the outer casing 10 (see...). Figure 2 )middle.

[0284] The cartridge 300 may include a mouthpiece 34 pivotally connected or coupled to the container head 33. The cartridge 300 may include a sealing cap 35.

[0285] When the cartridge 300 is assembled into the receiving space 11, the head cover 23 of the upper shell 20 can be positioned above the container head 33.

[0286] The flow sensor 60 can detect the airflow introduced into the cartridge 300 via the first inlet 3901.

[0287] Reference Figure 34 The cartridge 300 can be fitted into the gear mounting hole 411 formed in the cartridge gear 41. The cartridge 300 can be fitted in the direction of the rotation axis of the gear mounting hole 411.

[0288] The inner peripheral protrusion 416 can be fitted into the first guide slit 3916 and the second guide slit 326. The inner peripheral protrusion 416 guides the cartridge 300 so that the inner peripheral protrusion 416 slides along the first guide slit 3916 and the second guide slit 326 while the cartridge 300 is fitted into the receiving space 11. The first guide slit 3916 and the second guide slit 326 can sequentially contact the inner peripheral protrusion 416.

[0289] The first guide slit 3916 may include a plurality of first guide slits 3916 arranged in the circumferential direction of the smoke cartridge 300.

[0290] The circumferential direction of the smoke cartridge 300 can be the same as the rotation direction of the second container 32.

[0291] When the smoke cartridge 300 is fully assembled into the receiving space 11, the protrusion 117 remains (see Figure 12 It can be fitted into the retaining groove 9317 to hold the first container 39 in place. When the second container 32 is rotated, the first container 39 can be held in place.

[0292] The width w3 of the first guide slit 3916 may become equal to the width w2 of the lower end of the second guide slit 326 at the portion where it abuts the lower end. The width w3 of the first guide slit 3916 may be equal to or greater than the width w1 of the upper portion of the second guide slit 326. The width w3 of the first guide slit 3916 may be greater than the width w0 of the inner peripheral protrusion 416 (see...). Figure 13 ).

[0293] Therefore, even when the first guide slit 3916 and the second guide slit 326 are not aligned, when the cartridge 300 is assembled into the gear assembly hole 411, the inner peripheral protrusion 416 slides along the side surfaces of the first guide slit 3916 and the second guide slit 326, thereby aligning the first guide slit 3916 and the second guide slit 326.

[0294] Therefore, since the first disc orifice 3259 is precisely connected to the lower chamber orifice 323, the reduction in aerosol flow efficiency can be prevented.

[0388] Therefore, aerosols can easily flow along evaporation channel 3935.

[0389] Reference Figure 39 The coil 3941 can be configured to have a surrounding evaporation channel 3935 (see Figure 36 The coil 3941 can extend in a spiral shape and can extend in the longitudinal direction of the core 393.

Coil 3941 can be positioned closer to the outlet 3937 of evaporation channel 3935 than to the inlet 3936 of evaporation channel 3935 (see...). Figure 37 ).

[0391] Therefore, the aerosol heated to a high temperature can be introduced into the second container 32.

[0392] Reference Figure 40 The coil 3941 can be configured to have a surrounding evaporation channel 3935 (see Figure 36 The coil 3941 can extend in a spiral shape and can extend in the longitudinal direction of the core 393.

[0393] Coil 3941 may be located near inlet 3936 in evaporation channel 3935 (see...) Figure 37 It can be located near the outlet 3937 in the evaporation channel 3935 (see...).

[0400] In one embodiment, the aerosol generating device 1000 may consist only of a main body (e.g., Figure 1 The device consists of a housing 10 and an upper housing 20. In this case, the components included in the aerosol generating device 1000 may be located within the main body. In another embodiment, the aerosol generating device 1000 may consist of a cartridge containing an aerosol generating substance (e.g., a cartridge containing an aerosol generating substance). Figure 2 The smoke cartridge 30 shown) and the main body (e.g., Figure 2 The device consists of an outer casing 10 and an upper casing 20. In this case, the components included in the aerosol generating device 1000 may be located in at least one of the main body or the cartridge.

[0401] The communication interface 1010 may include at least one communication module for communicating with external devices and / or networks. For example, the communication interface 1010 may include a communication module for wired communication, such as Universal Serial Bus (USB). For example, the communication interface 1010 may include a communication module for wireless communication, such as Wi-Fi, Bluetooth, Bluetooth Low Energy (BLE), ZigBee, or Near Field Communication (NFC).

[0402] The input / output interface 1020 may include an input device (not shown) for receiving commands from a user and / or an output device (not shown) for outputting information to a user. For example, the input device may include a touch panel, physical buttons, a microphone, etc. For example, the output device may include: a display device for outputting visual information, such as a monitor or light-emitting diode (LED); an audio device for outputting auditory information, such as a speaker or buzzer; a motor for outputting tactile information such as tactile effects (e.g., Figure 3 Vibration motor 90 shown, etc.

[0403] The input / output interface 1020 can send data corresponding to commands input by the user via the input device to another component (or other component) of the aerosol generating device 1000, and can output information corresponding to data received from another component (or other component) of the aerosol generating device 1000 via the output device.

[0404] The aerosol generation module 1030 can generate aerosols from aerosol generating substances. Here, the aerosol generating substances can be liquid, solid, or gel-like substances capable of generating aerosols, or a combination of two or more aerosol generating substances.

[0405] According to one embodiment, the liquid aerosol generating substance may be a liquid comprising tobacco-containing materials having volatile tobacco flavor components. According to another embodiment, the liquid aerosol generating substance may be a liquid comprising non-tobacco materials. For example, the liquid aerosol generating substance may include water, solvents, nicotine, plant extracts, flavorings, seasonings, vitamin mixtures, etc.

[0406] Solid aerosol generating materials may include solid materials based on tobacco raw materials, such as reconstituted tobacco sheets, shredded tobacco, or granular tobacco. Additionally, solid aerosol generating materials may include solid materials containing flavor modifiers and flavoring ingredients. For example, flavor modifiers may include calcium carbonate, sodium bicarbonate, calcium oxide, etc. Flavoring ingredients may include natural materials such as herbal granules, or materials containing aromatic components (e.g., silica, zeolite, or dextrin).

[0407] In addition, aerosol-generating substances may also include aerosol forming agents such as glycerol or propylene glycol.

[0408] The aerosol generation module 1030 may include at least one heater (e.g., Figure 3 Heater 314 shown).

[0409] The aerosol generation module 1030 may include a resistance heater. For example, the resistance heater may include at least one conductive rail and may be heated as current flows through the conductive rail. In this case, the aerosol generating material may be heated by the heated resistance heater.

[0410] The conductive track may include a resistive material. In one example, the conductive track may be formed of a metallic material. In another example, the conductive track may be formed of a ceramic material, carbon, a metal alloy, or a composite of a ceramic material and a metal.

[0411] Resistance heaters may include conductive tracks formed in any of a variety of shapes. For example, conductive tracks may be formed in any of the following shapes: tubular, plate-shaped, needle-shaped, rod-shaped, and coil-shaped.

[0412] The aerosol generation module 1030 may include a heater using an induction heating method. For example, the induction heater may include a conductive coil, and an alternating magnetic field that periodically changes direction can be generated by adjusting the current flowing through the conductive coil. When the alternating magnetic field is applied to a magnet, energy loss may occur in the magnet due to eddy current losses and hysteresis losses, and the lost energy can be released as heat. Therefore, the aerosol-generating material disposed adjacent to the magnet can be heated. Here, the object that generates heat due to the magnetic field may be referred to as a sensor.

[0413] In addition, the aerosol generation module 1030 can generate ultrasonic vibrations, thereby generating aerosols from aerosol generating substances.

[0414] The aerosol generation module 1030 may be referred to as a cartomizer, atomizer, or vaporizer.

[0415] The memory 1040 can store programs for processing and controlling various signals in the controller 1070, and can also store the data being processed and the data to be processed.

[0416] For example, memory 1040 may store applications designed to perform various tasks that can be processed by controller 1070, and some of the stored applications may be selectively provided in response to requests from controller 1070.

[0417] For example, the memory 1040 may store data regarding the operating time of the aerosol generating device 1000, the maximum number of inhalations, the current number of inhalations, at least one temperature curve, at least one power curve, and the user's inhalation pattern. Here, "inhalation" refers to the user's inhalation, and "inhalation" means the act of a user allowing air or other substances to enter the user's oral cavity, nasal cavity, or lungs through the user's mouth or nose.

[0418] The memory 1040 may include at least one of volatile memory (e.g., dynamic random access memory (DRAM), static random access memory (SRAM) or synchronous dynamic random access memory (SDRAM)), non-volatile memory (e.g., flash memory), hard disk drive (HDD) or solid-state drive (SSD)).

[0419] The sensor module 1050 may include at least one sensor.

[0420] For example, sensor module 1050 may include a sensor for sensing inhalation (hereinafter referred to as "inhalation sensor"). In this case, the inhalation sensor may be implemented as a pressure sensor or a flow sensor 60.

[0421] For example, sensor module 1050 may include a voltage sensor for sensing the voltage applied to a component (e.g., battery 1060) provided in aerosol generating apparatus 1000 and / or a current sensor for sensing current.

[0422] For example, sensor module 1050 may include a sensor (hereinafter referred to as a "temperature sensor") for sensing the temperature of the heater included in aerosol generation module 1030 and the temperature of the aerosol-generating substance. In this case, the heater included in aerosol generation module 1030 may also be used as a temperature sensor. For example, the resistive material of the heater may be a material having a predetermined temperature coefficient of resistance. Sensor module 1050 can measure the resistance of the heater as a function of temperature, thereby sensing the temperature of the heater.

[0423] For example, if the main body of the aerosol generating device 1000 is configured to allow cigarettes to be inserted therein, the sensor module 1050 may include a sensor for sensing the insertion of a cigarette (hereinafter referred to as a "cigarette detection sensor").

[0424] For example, when the aerosol generating device 1000 includes a cartridge, the sensor module 1050 may include a sensor (hereinafter referred to as a "cartridge detection sensor") for sensing the installation of the cartridge onto and off the body and the position of the cartridge.

[0425] For example, if the second container 32 of the cartridge is rotatable, the sensor module 1050 may include a sensor (hereinafter referred to as a "rotation detection sensor") for outputting a signal indicating the rotation of the second container 32.

[0426] Cigarette detection sensors, cartridge detection sensors, and / or rotation detection sensors can be implemented as inductive sensors, capacitive sensors, resistive sensors, or Hall sensors (or Hall ICs) using the Hall effect.

[0427] The first terminal 164, which is included in the body of the aerosol generating device 1000 and transmits power to the cartridge, can be used as a cartridge detection sensor. For example, the sensor module 1050 can sense the installation of the cartridge into and removal from the body based on the current flowing through the first terminal 164 or the voltage applied to the first terminal 164.

[0428] A rotary switch 44, which is coaxially mounted with the dial gear 42 and / or the dial 43 and outputs an electrical signal indicating the rotation of the dial gear 42 and / or the dial 43, can be used as a rotation detection sensor.

[0429] Battery 1060 can supply power for the operation of aerosol generating apparatus 1000 under the control of controller 1070. Battery 1060 can also supply power to other components disposed in aerosol generating apparatus 1000 (e.g., communication module included in communication interface 1010, output device included in input / output interface 1020, and heater included in aerosol generating module 1030).

[0430] Battery 1060 can be a rechargeable battery or a disposable battery. For example, battery 1060 can be a lithium-ion battery or a lithium polymer (Li-polymer) battery. However, this disclosure is not limited thereto. For example, when battery 1060 is rechargeable, its charge rate (C-rate) can be 10C, and its discharge rate (C-rate) can be from 10C to 20C. However, this disclosure is not limited thereto. In addition, for stable use, battery 1060 can be manufactured such that even after performing 2000 charge / discharge cycles, 80% or more of the total capacity can be maintained.

[0431] The aerosol generating apparatus 1000 may also include a battery protection circuit module (PCM) (not shown), which is a circuit for protecting the battery 1060. The battery protection circuit module (PCM) may be disposed adjacent to the upper surface of the battery 1060. For example, to prevent overcharging and over-discharging of the battery 1060, the battery protection circuit module (PCM) may disconnect the electrical path to the battery 1060 when a short circuit occurs in the circuit connected to the battery 1060, when an overvoltage is applied to the battery 1060, or when an overcurrent flows through the battery 1060.

[0432] The aerosol generating apparatus 1000 may also include a charging terminal (not shown) for inputting power supplied from an external source. For example, a power cord may be connected to the charging terminal located on one side of the main body of the aerosol generating apparatus 1000, and the aerosol generating apparatus 1000 may use the power supplied through the power cord connected to the charging terminal to charge the battery 1060. In this case, the charging terminal may be a wired terminal for USB communication.

[0433] The aerosol generating device 1000 can wirelessly receive power supplied from an external source via the communication interface 1010. For example, the aerosol generating device 1000 can use an antenna included in a communication module for wireless communication to wirelessly receive power and can use the wirelessly supplied power to charge the battery 1060.

[0434] The controller 1070 controls the overall operation of the aerosol generating apparatus 1000. The controller 1070 can be connected to the various components disposed in the aerosol generating apparatus 1000, and can send signals to and / or receive signals from the various components, thereby controlling the overall operation of the various components.

[0435] The controller 1070 may include at least one processor, and the processor included therein may be used to control the overall operation of the aerosol generating apparatus 1000. Here, the processor may be a general-purpose processor such as a central processing unit (CPU). Of course, the processor may be a special-purpose device such as an application-specific integrated circuit (ASIC), or any other hardware-based processor.

[0436] The controller 1070 can perform any of a number of functions of the aerosol generating device 1000. For example, the controller 1070 can perform any of a number of functions of the aerosol generating device 1000 (e.g., preheating function, heating function, charging function, and cleaning function) based on the status of the various components set in the aerosol generating device 1000 and user commands received through the input / output interface 1020.

[0437] The controller 1070 can control the operation of various components disposed in the aerosol generating device 1000 based on data stored in the memory 1040. For example, the controller 1070 can control the supply of a predetermined amount of power from the battery 1060 to the aerosol generating module 1030 based on data about temperature profiles, power profiles, and user inhalation patterns stored in the memory 1040.

[0438] The controller 1070 may use an inhalation sensor included in the sensor module 1050 to determine whether inhalation has occurred or not. For example, the controller 1070 may check for temperature changes, flow rate changes, pressure changes, and voltage changes in the aerosol generating device 1000 based on the values ​​sensed by the inhalation sensor, and may determine whether inhalation has occurred or not based on the check results.

[0439] The controller 1070 can control the operation of various components in the aerosol generating device 1000 based on whether inhalation occurs or not and / or the number of inhalations.

[0440] Upon determining that intake has occurred, controller 1070 may perform control such that a predetermined amount of power is supplied to the heater according to a power curve stored in memory 1040. For example, controller 1070 may supply power to the heater at a preset amount per unit time during a predetermined heating time based on the power curve stored in memory 1040.

[0441] The controller 1070 can perform control to change or maintain the temperature of the heater based on the temperature profile stored in the memory 1040.

[0442] For example, controller 1070 can perform control such that current pulses with a predetermined frequency and a predetermined duty cycle are supplied to the heater using a pulse width modulation (PWM) method. In this case, controller 1070 can control the amount of power supplied to the heater by adjusting the frequency and duty cycle of the current pulses.

[0443] For example, controller 1070 can determine the target temperature to be controlled based on a temperature profile. In this case, controller 1070 can use a proportional-integral-derivative (PID) method to control the amount of power supplied to the heater, which is a feedback control method that uses the difference between the heater temperature and the target temperature, the value obtained by integrating the difference with respect to time, and the value obtained by differentiating the difference with respect to time.

[0444] Although PWM and PID methods have been described as examples of methods for controlling the power supply to the heater, this disclosure is not limited thereto, and any of a variety of control methods such as proportional-integral (PI) or proportional-derivative (PD) methods may be employed.

[0445] The controller 1070 can perform control to interrupt the power supply to the heater according to predetermined conditions. For example, the controller 1070 can perform control to interrupt the power supply to the heater when the cigarette is removed, when the cartridge is disassembled, when the number of inhalations reaches a preset maximum number of inhalations, when no inhalation is sensed for a preset time period or longer, or when the remaining capacity of the battery 1060 is less than a predetermined value.

[0446] The controller 1070 can calculate the remaining capacity of the battery 1060 based on the power stored in the battery 1060. For example, the controller 1070 can calculate the remaining capacity of the battery 1060 based on the values ​​sensed by the voltage sensor and / or current sensor included in the sensor module 1050.

[0447] Controller 1070 can determine multiple granulation chambers (e.g., Figure 3 The aerosol generated by the heater in the granulation chambers 321 and 322 shown is passed through the granulation chamber (hereinafter referred to as the "application chamber"). That is, the application chamber can be one of the granulation chambers connected to the first connection channel 319. For example, the controller 1070 can determine whether the second container 32 is rotating based on the signal received from the rotation detection sensor and can determine the granulation chamber through which the aerosol passes among the multiple granulation chambers based on the rotation of the second container 32.

[0448] The controller 1070 can determine whether the plurality of granulation chambers are in the correct position based on the signal received from the rotation detection sensor. Here, the correct position of the plurality of granulation chambers may be a position in which one of the plurality of granulation chambers is selectively connected to the first connection channel 319, and another of them is sealed to prevent air from flowing into it from the outside.

[0449] When multiple granulation chambers are not in the correct position, the controller 1070 can interrupt the power supply to the heater.

[0450] The controller 1070 can determine the extent to which the cartridge has been used. For example, the controller 1070 can determine the extent to which the cartridge has been used based on the number of inhalations, the temperature of the heater, the power supplied to the heater, the flow rate changes during inhalation, and the pressure changes during inhalation.

[0451] In the e-cigarette cartridge, there is a liquid chamber (e.g., Figure 3 In the case of the liquid chamber 311 and the granulation chamber shown, the controller 1070 can determine the degree to which the liquid chamber is used and the degree to which the granulation chamber is used. On the other hand, in the case where the cartridge includes multiple granulation chambers, the controller 1070 can independently determine the degree to which each granulation chamber is used.

[0452] The controller 1070 can store data about the tobacco cartridge in the memory 1040. If the tobacco cartridge includes a liquid chamber and a granulation chamber, the controller 1070 can store data about both the liquid chamber and the granulation chamber in the memory 1040. For example, the controller 1070 can store data about the degree to which the liquid chamber is used and data about the degree to which the granulation chamber is used in the memory 1040.

[0453] On the other hand, when the cartridge includes multiple granulation chambers, the controller 1070 can independently store data about each granulation chamber in the memory 1040.

[0454] The controller 1070 can update the data stored in the memory 1040 based on the installation / removal of the cartridge. For example, when the removal of the cartridge is sensed, the controller 1070 can initialize the data stored in the memory 1040.

[0455] When the installation of the cartridge is detected, the controller 1070 can determine the order of the multiple granulation chambers based on the signal received from the rotary switch 44, and can independently store data about each granulation chamber in the memory 1040 in the determined order.

[0456] With the dial gear 42 connected to a motor, the controller 1070 can control the operation of the motor to rotate the second container 32. Here, the motor for rotating the dial gear 42 can be a stepper motor. For example, when a user input for selecting any one of a plurality of granulation chambers is received via an input device, the controller 1070 can rotate the motor so that the selected granulation chamber is connected to the first connection channel 319.

[0457] In this situation, when the removal of the cartridge is sensed, the controller 1070 can perform control to fix the position of the dial gear 42. That is, even when the cartridge is removed from the housing 10, the controller 1070 can omit the control of the motor for rotating the dial gear 42 when a user input for rotating the dial gear 42 is received via the input device.

[0458] Figure 46 This is a flowchart illustrating an operation method of an aerosol generating apparatus according to an embodiment of the present disclosure.

[0459] Reference Figure 46 In operation S4601, the aerosol generating apparatus 1000 can determine the application chamber through which the aerosol generated in the first container 31 passes, among the plurality of granulation chambers included in the second container 32.

[0460] Reference Figure 47The rotary switch 44 may include a shaft 4710 rotatable about a rotation axis 4705, a fixed contact 4720, and a plurality of variable contacts 4730 arranged in a circular shape.

[0461] When the shaft 4710 of the rotary switch 44 rotates in response to the rotation of the dial gear 42 and / or the dial 43, the fixed contact 4720 can be electrically connected via the shaft 4710 to one of the variable contacts 4730, and the rotary switch 44 can output an electrical signal corresponding to the electrical connection between the fixed contact 4720 and the selected variable contact 4730.

[0462] The aerosol generating apparatus 1000 can determine the first variable contact 4731, which corresponds to the electrical signal output from the rotary switch 44 during initial setting, as the reference contact among a plurality of variable contacts 4730. The number of variable contacts 4730 can be equal to or greater than the number of granulation chambers included in the second container 32.

[0463] In addition, the aerosol generating apparatus 1000 can determine the variable contacts corresponding to each granulation chamber included in the second container 32 based on the position of the first variable contact 4731, which is determined as the reference contact.

[0464] Reference Figure 48 When the number of granulation chambers included in the second container 32 is two, the aerosol generating apparatus 1000 can determine the first variable contact 4731 and the second variable contact 4737, which are arranged in a circular shape, as variable contacts corresponding to each granulation chamber included in the second container 32.

[0465] When the number of granulation chambers included in the second container 32 is three, the aerosol generating apparatus 1000 can determine the first variable contact 4731, which is arranged in a circular shape, and a plurality of third variable contacts 4735 and 4739, which are set to divide the circle into three equal parts, as variable contacts corresponding to each granulation chamber included in the second container 32.

[0466] When the number of granulation chambers included in the second container 32 is four, the aerosol generating apparatus 1000 can determine the first variable contact 4731, which is arranged in a circular shape, and a plurality of fourth variable contacts 4734, 4737 and 4740, which are configured to divide the circle into four equal parts, as variable contacts corresponding to each granulation chamber included in the second container 32.

[0467] After determining the variable contacts corresponding to each granulation chamber included in the second container 32, the aerosol generating apparatus 1000 can determine the granulation chamber corresponding to the first variable contact 4731 as the application chamber when the variable contact corresponding to the electrical signal output from the rotary switch 44 does not change.

[0468] Refer to Figure 46 In operation S4602, the aerosol generating device 1000 can check the usage of the granulation chamber identified as the application chamber, and can determine whether the usage of the granulation chamber is equal to or greater than a predetermined reference. Here, the predetermined reference can be set based on the maximum number of air intakes preset for each granulation chamber and the maximum time period for supplying power to each granulation chamber per unit time.

[0469] For example, the aerosol generating apparatus 1000 can check the extent to which the granulation chamber, which is identified as an application chamber, is being used based on data about the use of the granulation chamber stored in the memory 1040.

[0470] When the granulation chamber, which is determined to be the application chamber, is used to a less than predetermined standard, the aerosol generating device 1000 can supply power to the heater in operation S4603 based on the temperature curve and / or power curve stored in the memory 1040.

[0471] The aerosol generating device 1000 can use an inhalation sensor included in the sensor module 1050 to determine whether inhalation is detected. In this case, when inhalation is detected, the aerosol generating device 1000 can supply power to the heater at a preset amount per unit time based on the power curve stored in the memory 1040.

[0472] For example, the aerosol generating device 1000 can supply power to the heater at a preset amount per unit time during a preset time period starting when inhalation is sensed.

[0473] For example, the aerosol generating device 1000 can supply power to the heater at a preset amount per unit time from the time the inhalation is sensed until the inhalation ends.

[0474] Furthermore, regarding the granulation chamber identified as the application chamber, the aerosol generating device 1000 can update the usage data of the granulation chamber stored in the memory 1040. For example, when inhalation is sensed, the aerosol generating device 1000 can increase the current inhalation count corresponding to the granulation chamber identified as the application chamber.

[0475] On the other hand, when the granulation chamber, which is designated as the application chamber, is used to a degree equal to or greater than a predetermined reference, the aerosol generating device 1000 may interrupt the power supply to the heater during operation S4604. For example, when the current number of intakes corresponding to the granulation chamber, which is designated as the application chamber, reaches a preset maximum number of intakes, the aerosol generating device 1000 may interrupt the power supply to the heater.

[0476] In addition, when the granulation chamber, which is determined to be the application chamber, is used to a degree equal to or greater than a predetermined standard, the aerosol generating device 1000 can output a message prompting a change in the application chamber via an output device.

[0477] For example, if there is a granulation chamber that is smaller than a predetermined standard when it is used in a granulation chamber other than the granulation chamber that is designated as the application chamber, the aerosol generating device 1000 can output a message on the display prompting the application chamber to be changed to the corresponding granulation chamber.

[0478] For example, when there are multiple granulation chambers that are smaller than a predetermined reference, the aerosol generating apparatus 1000 may output a message prompting the application chamber to be changed to the granulation chamber that is adjacent to the granulation chamber currently identified as the application chamber.

[0479] In addition, based on the position of the variable contacts in the rotary switch 44 corresponding to each granulation chamber, the aerosol generating device 1000 can output a message (including rotation direction and rotation angle) prompting a change in the application chamber via an output device.

[0480] The aerosol generating apparatus 1000 can determine in operation S4605 whether the usage of all plurality of granulation chambers is equal to or greater than a predetermined reference. For example, the aerosol generating apparatus 1000 can determine whether any of the current inhalation counts corresponding to each of the plurality of granulation chambers included in the second container 32 has reached a preset maximum inhalation count.

[0481] When at least one granulation chamber smaller than a predetermined reference is used, the aerosol generating apparatus 1000 can determine in operation S4606 whether the application chamber has changed. For example, the aerosol generating apparatus 1000 can monitor whether a variable contact connected to a fixed contact via shaft electricity has changed based on an electrical signal output from the rotary switch 44. When the variable contact changes, the aerosol generating apparatus 1000 can determine that the application chamber has changed.

[0482] When the application chamber changes, the process proceeds to operation S4601, so that the aerosol generating apparatus 1000 can again determine the application chamber through which the aerosol generated in the first container 31 passes among the plurality of granulation chambers included in the second container 32.

[0483] When the application chamber remains unchanged, the process proceeds to operation S4602, so the aerosol generating apparatus 1000 can control the power supply to the heater based on the use of the granulation chamber, which is determined to be the application chamber.

[0484] When the usage of all multiple granulation chambers is equal to or greater than a predetermined baseline, the aerosol generating apparatus 1000 may determine in operation S4607 that it is impossible for the user to use the multiple granulation chambers to generate aerosols. In this case, the aerosol generating apparatus 1000 may output a message indicating that the multiple granulation chambers are unavailable via an output device.

[0485] The aerosol generating device 1000 can continuously monitor whether the application chamber changes throughout its operation. When the application chamber changes, the process proceeds to operation S4601, so that the aerosol generating device 1000 can re-determine the application chamber.

[0486] Figure 49 This is a flowchart illustrating an operation method of an aerosol generating apparatus according to another embodiment of the present disclosure. References will be omitted. Figures 46 to 48 A detailed description of the same content.

[0487] Reference Figure 49 In operation S4901, the aerosol generating apparatus 1000 can use a cartridge detection sensor included in the sensor module 1030 to sense that a cartridge comprising multiple granulation chambers is mounted onto the housing 10. For example, the aerosol generating apparatus 1000 can sense that a cartridge is mounted onto the housing 10 based on the current flowing through a first terminal 164 that transmits power to the cartridge or the voltage applied to the first terminal 164.

[0488] In operation S4902, the aerosol generating device 1000 can determine the position and sequence of multiple granulation chambers included in the cartridge.

[0489] For example, at the moment when the installation of the cartridge is sensed, the aerosol generating device 1000 can determine the variable contact corresponding to the electrical signal output from the rotary switch 44 as the reference contact. Furthermore, the aerosol generating device 1000 can determine the variable contact corresponding to each of the multiple granulation chambers based on the position of the variable contact determined as the reference contact, according to the number of granulation chambers.

[0490] The aerosol generating apparatus 1000 can determine the position and sequence of multiple granulation chambers based on the determined position and sequence of variable contacts. Furthermore, the aerosol generating apparatus 1000 can store data regarding the use of each of the multiple granulation chambers in a memory 1040 based on the position and sequence of the multiple granulation chambers.

[0491] In operation S4903, the aerosol generating apparatus 1000 can determine the application chamber through which the aerosol generated in the first container 31 among a plurality of granulation chambers passes. For example, the aerosol generating apparatus 1000 can determine the granulation chamber corresponding to a variable contact that is determined as a reference contact at the time point at which the installation of the cartridge is sensed as the application chamber.

[0492] In operation S4904, the aerosol generating apparatus 1000 can check the use of the granulation chamber identified as the application chamber, and can determine whether the use of the granulation chamber is equal to or greater than a predetermined reference.

[0493] When the usage of the granulation chamber, which is determined to be the application chamber, is less than a predetermined baseline, the aerosol generating apparatus 1000 can determine in operation S4905 whether inhalation has been detected using the inhalation sensor included in the sensor module 1050. For example, the aerosol generating apparatus 1000 can monitor whether inhalation occurs during a predetermined time period.

[0494] When inhalation is sensed, the aerosol generating device 1000 can supply power to the heater at a preset amount per unit time based on the power curve stored in the memory 1040 during operation S4906. For example, the aerosol generating device 1000 can supply power to the heater at a preset amount per unit time during a preset time period from the time inhalation is sensed or from the time inhalation is sensed until the end of inhalation.

[0495] In addition, in response to sensing air intake, the aerosol generating device 1000 can increase the current air intake number corresponding to the granulation chamber identified as the application chamber.

[0496] On the other hand, when the use of the granulation chamber, which is determined to be the application chamber, is equal to or greater than a predetermined reference, the aerosol generating device 1000 may interrupt the power supply to the heater in operation S4907.

[0497] In addition, when the use of the granulation chamber, which is determined to be the application chamber, is equal to or greater than a predetermined standard, the aerosol generating device 1000 can output a message prompting a change of application chamber through the output device.

[0498] In operation S4908, the aerosol generating apparatus 1000 can determine whether the use of all plurality of granulation chambers is equal to or greater than a predetermined reference.

[0499] When at least one granulation chamber is used at a rate less than a predetermined reference, the aerosol generating apparatus 1000 can determine in operation S4909 whether the application chamber has changed. On the other hand, the aerosol generating apparatus 1000 can determine whether the application chamber has changed when the granulation chamber determined to be the application chamber is used at a rate less than a predetermined reference and when no inhalation is sensed during a predetermined time period.

[0500] When the application chamber changes, the process proceeds to operation S4903, so that the aerosol generating apparatus 1000 can re-identify the application chamber among the multiple granulation chambers.

[0501] When the application chamber remains unchanged, the process proceeds to operation S4904, so the aerosol generating apparatus 1000 can control the power supply to the heater based on the use of the granulation chamber, which is determined to be the application chamber.

[0502] When the usage of all multiple granulation chambers is equal to or greater than a predetermined baseline, the aerosol generating apparatus 1000 may determine in operation S4910 that the user cannot use the multiple granulation chambers to generate aerosols. In this case, the aerosol generating apparatus 1000 may output a message indicating that the multiple granulation chambers are unavailable via an output device.

[0503] In operation S4911, the aerosol generating device 1000 can determine whether the cartridge has been removed from the housing 10. For example, the aerosol generating device 1000 can sense the removal of the cartridge from the housing 10 based on the current flowing through the first terminal 164 that transmits power to the cartridge or the voltage applied to the first terminal 164.

[0504] When the cartridge is removed from the casing 10, the aerosol generating device 1000 can initialize the data stored in the memory 1040 in operation S4912. For example, the aerosol generating device 1000 can remove data from the memory 1040 regarding the use of each of the plurality of granulation chambers.

[0505] The aerosol generating device 1000 can continuously monitor whether the application chamber changes throughout its operation. When the application chamber changes, the process proceeds to operation S4901, so that the aerosol generating device 1000 can re-determine the application chamber.

[0506] Furthermore, the aerosol generating device 1000 can continuously monitor whether the cartridge is removed from the casing 10 throughout its operation. When the cartridge is removed, the process proceeds to operation S4912, so the aerosol generating device 1000 can initialize the data stored in the memory 1040.

[0507] When the installation of a tobacco cartridge is sensed within a predetermined time period after the cartridge has been removed from the housing 10, the aerosol generating device 1000 can maintain the data stored in the memory 1040 instead of initializing it. That is, when the installation of a tobacco cartridge is sensed within a predetermined time period (e.g., 2 seconds) after the cartridge has been removed from the housing 10, the aerosol generating device 1000 can determine that the cartridge has not been completely removed from the receiving space 11 in the housing 10 and has been reinstalled while maintaining the position of multiple granulation chambers, and can maintain the continuity of the data stored in the memory 1040 (e.g., number of inhalations, use of granulation chambers, etc.).

[0508] Furthermore, when the installation of the tobacco cartridge is sensed within a predetermined time period after the cartridge has been removed from the casing 10, the aerosol generating device 1000 can output a message prompting the user to select whether to initialize the data stored in the memory 1040 via an output device. Additionally, the aerosol generating device 1000 can determine whether to initialize the data stored in the memory 1040 in response to a command received via an input device.

[0509] As described above, according to at least one embodiment of this disclosure, the use of multiple granulation chambers can ensure optimal medium quality. Furthermore, according to at least one embodiment of this disclosure, the granulation chamber through which the aerosol passes can be changed, thereby providing the user with various media without having to replace the cartridge. Additionally, according to at least one embodiment of this disclosure, with the cartridge installed in the main unit, the user can appropriately select the desired medium using a dial 43 or similar device in response to a message output through the output device.

[0510] Reference Figures 1 to 49 According to one aspect of this disclosure, an aerosol generating apparatus 1000 may include: a first container 31 configured to contain an aerosol generating substance; a heater 314 configured to heat the aerosol generating substance; a second container 32 configured to be rotatable about its axis of rotation and including a plurality of compartments; a first sensor (e.g., a rotation detection sensor) configured to output a signal indicating rotation of the second container 32; and a controller 1070. In response to a signal received from the first sensor, the controller 1070 may determine which of the plurality of compartments the aerosol generated in the first container 31 passes through.

[0511] In addition, according to another aspect of this disclosure, the controller 1070 can determine the use of each of the plurality of rooms.

[0512] Additionally, according to another aspect of this disclosure, the aerosol generating apparatus may also include a second sensor (e.g., a flow sensor 60) configured to sense a user's inhalation. When a user's inhalation is sensed by the second sensor while the first chamber among a plurality of chambers is determined to be the chamber through which the aerosol passes, the controller 1070 may update data regarding the use of the first chamber.

[0513] Furthermore, according to another aspect of this disclosure, when the first chamber among a plurality of chambers is determined to be the chamber through which the aerosol passes, the controller 1070 can determine whether the usage of the first chamber is equal to or greater than a preset reference. When the usage of the first chamber is less than the preset reference, the controller 1070 can execute control to supply power to the heater 314. When the usage of the first chamber is equal to or greater than the preset reference, the controller 1070 can execute control to interrupt the power supply to the heater 314.

[0514] Furthermore, according to another aspect of this disclosure, the aerosol generating apparatus may also include an output device configured to output a message. When the use of the first chamber among a plurality of chambers, which is determined to be the chamber through which the aerosol passes, is equal to or greater than a preset reference, the controller 1070 may output a message prompting a change in chamber via the output device.

[0515] Furthermore, according to another aspect of this disclosure, the controller 1070 can determine whether a second chamber smaller than a preset reference exists among the chambers other than the first chamber. When a second chamber exists, the controller 1070 can output a message prompting the aerosol to be passed through the second chamber instead of the first chamber via an output device.

[0516] In addition, according to another aspect of this disclosure, when multiple second chambers are provided, the controller 1070 can determine the third chamber that is adjacent to the first chamber among the multiple second chambers, and can output a message through the output device to prompt that the chamber through which the aerosol passes is changed from the first chamber to the third chamber.

[0517] In addition, according to another aspect of this disclosure, when the usage of all multiple rooms is equal to or greater than a preset reference, the controller 1070 may output a message indicating that multiple rooms are unavailable via an output device.

[0518] Additionally, according to another aspect of this disclosure, the aerosol generating apparatus may further include: a housing 10 having a receiving space formed therein to allow insertion of a cartridge 30; and a third sensor (e.g., a cartridge detection sensor) configured to sense the insertion of the cartridge 30. The cartridge 30 may include at least one of a first container 31 or a second container 32.

[0519] In addition, according to another aspect of this disclosure, when the installation of the cartridge 30 is detected using the third sensor, the controller 1070 can determine the first chamber corresponding to the signal received from the first sensor as the chamber through which the aerosol passes, and can determine the order of the chambers other than the first chamber based on the first chamber.

[0520] In addition, according to another aspect of this disclosure, when the installation of the cartridge 30 is detected using a third sensor, the controller 1070 can initialize data regarding the use of multiple compartments.

[0521] In addition, according to another aspect of this disclosure, when the installation of the cartridge 30 is sensed within a predetermined time period after the removal of the cartridge 30 is sensed, the controller 1070 can maintain data on the use of the multiple compartments, and when the installation of the cartridge 30 is not sensed within a predetermined time period after the removal of the cartridge 30 is sensed, the controller 1070 can initialize the data on the use of the multiple compartments.

[0522] Additionally, according to another aspect of this disclosure, the aerosol generating apparatus may further include an input device configured to receive commands corresponding to user input and an output device configured to output messages. When the installation of the cartridge 30 is sensed within a predetermined time period after the removal of the cartridge 30 is sensed, the controller 1070 may output a message prompting the user to select whether to maintain data regarding the use of the multiple compartments via the output device, and may determine whether to initialize the data regarding the use of the multiple compartments in response to a command received via the input device.

[0523] Additionally, according to another aspect of this disclosure, the aerosol generating apparatus may further include a first gear (e.g., a cartridge gear 41) whose inner peripheral surface meshes with the outer peripheral surface of the second container 32, and a second gear (e.g., a dial gear 42) that meshes with the outer peripheral surface of the first gear to rotate. The first sensor may be a rotary switch 44 coaxially mounted with the second gear.

[0524] In addition, according to another aspect of this disclosure, the plurality of chambers may be arranged in a circumferential direction about the rotation axis of the second container 32.

[0525] The specific embodiments or other embodiments of this disclosure described above are not mutually exclusive or different from each other. Any or all elements of the embodiments of this disclosure described above may be combined with each other in terms of configuration or function.

[0526] For example, configuration "A" described in one embodiment and accompanying drawings of this disclosure can be combined with configuration "B" described in another embodiment and accompanying drawings of this disclosure.
