The air passing 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 can pass through the evaporation channel 318 together with the aerosol contained in the evaporation chamber 312. The aerosol passing through the evaporation channel 318 can be sequentially introduced into the second granulation chamber 322 through the first connecting channel 319 and the lower chamber hole 323. The aerosol can sequentially pass through the medium in the second granulation chamber 322, the upper chamber hole 324 and the first outlet 302. The aerosol passing through the first outlet 302 can be discharged upward through the second inlet 341, the suction channel 343 and the second outlet 342.

[0133] The second guide slit 326 may extend in the longitudinal direction of the rotation axis of the second container 32. The second guide slit 326 may vertically guide the cartridge 30 along the inner peripheral protrusion 416. When the cartridge 30 is inserted into the receiving space 11, the inner peripheral protrusion 416 may be caught on the upper end of the second guide slit 326. The upper end of the second guide slit 326 may serve as a stopper configured to prevent the cartridge 30 from moving further downward.

[0135] The mouthpiece 34 may be pivotably connected or coupled to the container head 33 . Figure 5 A state in which the mouthpiece 34 is pivoted so as to be positioned at the first position is illustrated. Figure 6 A state in which the mouthpiece 34 is pivoted so as to be positioned at the second position is illustrated.

[0136] In the following, reference will be made to Figure 5 A state in which the mouthpiece 34 is pivoted so as to be positioned at the first position is described.

[0137] When the mouthpiece 34 is pivoted to be positioned in the first position, the mouthpiece 34 may be seated in the seat portion 14, thereby closing the upper portion of the housing 10. The mouthpiece 34 may close the opening O in the upper housing 20. One surface of the mouthpiece 34 may be exposed through the opening O to the outside.

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

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

[0140] Therefore, the medium contained in the cartridge and the internal components and the material used for vaporization can be protected from the external environment.

[0141] The sealing cover 35 may have an outer surface that is rounded in the direction in which the mouthpiece 34 pivots. Therefore, when the mouthpiece 34 pivots so as to be positioned in the first position, the sealing cover 35 will not get stuck on the surface surrounding the first outlet 302.

[0142] Next, we will refer to Figure 6 A state in which the mouthpiece 34 is pivoted so as to be positioned at the second position is described.

[0143] When the mouthpiece 34 is pivoted so as to be positioned at the second position, the mouthpiece 34 may be separated from the seating portion 14. The sealing cover 35 may be separated from the first outlet 302 so as to open the first outlet 302.

[0144] The first outlet 302 may contact the second inlet 341. The suction channel 343 in the mouthpiece 34 may communicate with the first outlet 302. The suction channel 343 in the mouthpiece 34 may 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 may be oriented to extend in the longitudinal direction of the cartridge 30. The suction channel 343 may be oriented to extend vertically. The sealing cover 35 may be provided to protrude toward the seating portion 14.

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

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

[0148] Suction channel 343 (see Figure 6 ) may be formed in the mouthpiece 34 and may extend in the forward and backward directions. The second inlet 341 may be located at one end of the suction channel 343. The second outlet 342 may be located at the other end of the suction channel 343. The distance between the pivot axis 355 and the second outlet 342 may be greater than the distance between the pivot axis 355 and the second inlet 341. The suction channel 343 may be referred to as a second channel 343.

[0149] Therefore, the user can inhale air while holding part of the second outlet 342 in his / her mouth.

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

The sealing cover 35 may be integrally formed with the mouthpiece 34. The sealing cover 35 may be coupled to the mouthpiece 34. The sealing cover 35 may be disposed closer to the second inlet 341 than the second outlet 342.

[0152] The mouthpiece 34 may be pivoted about a pivot axis 355. The pivot axis 355 may be considered as the center of the pivoting action or the pivot center of the mouthpiece 34. The pivot axis 355 may protrude from both side surfaces of the mouthpiece 34 or the sealing cover 35 in the right and left directions. The pivot axis 355 may be disposed perpendicular to the vertical direction. The pivot axis 355 may be located closer to the second inlet 341 than the second outlet 342.

When the mouthpiece 34 is in the first position, the first sealing surface 356 is disposed above the first outlet 302 to close the first outlet 302 (see Figure 5 When the mouthpiece 34 is in the first position, the first sealing surface 356 can contact the gasket 331 (see Fig.11 ), the gasket 331 is disposed around the first outlet 302. The gasket 331 may alternatively be referred to as a docking member or a docking ring.

[0155] The first sealing surface 356 may include a portion extending while being rounded in the direction in which the mouthpiece 34 pivots. The first sealing surface 356 may include a first plane portion 356a formed to have a plane surface and a first rounded portion 356b rounded in the direction in which the mouthpiece 34 pivots.

The first circular portion 356b may have a radius of curvature whose center is located adjacent to the pivot center of the mouthpiece 34.

[0157] Therefore, when the mouthpiece 34 pivots, the mouthpiece 34 can smoothly pivot between the first position and the second position without the first sealing surface 356 of the sealing cover 35 being caught on the surface surrounding the first outlet 302. The sealing surface 356 and / or the end of the sealing cover 35 may be spaced apart from the lower surface of the mouthpiece 34 so as to define a space S between the mouthpiece 34 and the end. The front side and the lower side of the space S may be surrounded by the extension 352 and the first sealing surface 356. The extension 352 and the first sealing surface 346 of the sealing cover 35 may define a hook-shaped portion.

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

[0159] Therefore, when the mouthpiece 34 is located at the first position, the first sealing surface 356 may come into contact with the first outlet 302 , and may press the first outlet 302 while being pushed toward the space S. As shown in FIG.

[0160] The mouthpiece 34 may include a second sealing surface 346 constituting a rear surface of the mouthpiece 34 and surrounding the second inlet 341. The second sealing surface 346 may define an outer surface of the mouthpiece 34 surrounding the second inlet 341.

[0162] The second sealing surface 346 may include a portion extending while being rounded in the direction in which the mouthpiece 34 pivots. The second sealing surface 346 may include a second plane portion 346a formed to have a plane surface and a second rounded portion 346b rounded in the direction in which the mouthpiece 34 pivots. The second plane portion 346a may be formed to be higher than the second rounded portion 346b.

[0163] The second circular portion 346b may constitute a surface extending while being circular in the direction in which the mouthpiece 34 pivots. The second circular portion 346b may have a predetermined curvature. The center of curvature of the second circular portion 346b may be located adjacent to the pivot center of the mouthpiece 34. The second plane portion 346a may extend from the second circular portion 346b in the upward direction of the mouthpiece 34 to define a plane.

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

[0165] The spring 344 may be connected to the mouthpiece 34. The spring 344 may be exposed to the outside of the mouthpiece 34 through a slit 354 formed in the sealing cover 35. A portion of the spring 344 may be exposed downward from the mouthpiece 34.

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 Fig.10 and Fig.11 , the mouthpiece 34 may be pivotably connected or coupled to the container head 33. A shaft hole 335 may be formed in both side surfaces of the container head 33. A pivot shaft 355 may be fitted into the shaft hole 335. The mouthpiece 34 may pivot about the pivot shaft 355, and the pivot shaft 355 is fitted into the shaft hole 335.

[0169] The container head 33 may be configured to have a cylindrical shape extending upward from the outer peripheral surface of the second container 32. A shaft hole 335 may be formed in both side surfaces of the upper portion of the container head 33. The container head 33 may be open at its upper surface so that the mouthpiece 34 is disposed in the container head 33. A portion of one side surface of the container head 33 may be open. The container head 33 may be configured so that its upper surface portion and the side surface portion are continuously opened, thereby having an "L" shape.

The first inclined surface 416a may be inclined toward the central axis of the receiving space 11 when the cigarette cartridge 30 moves in the direction of insertion into the receiving space 11. The first inclined surface 416a may be inclined toward the central axis of the receiving space 11 when moving downward.

[0193] The first inclined surface 416a may face the opening surface of the gear assembly hole 411. The first inclined surface 416a may face both the opening surface of the gear assembly hole 411 and the central axis of the gear assembly hole 411.

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

[0198] Therefore, the cigarette cartridge 30 can be easily taken out from the receiving space 11 .

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

[0200] Therefore, the cigarette 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 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 cartridge 30 can be easily inserted and removed.

[0203] Reference Figures 14 to 16 , the cartridge 30 may be inserted into the gear assembly hole 411 formed in the cartridge gear 41. The cartridge 30 may be inserted along the direction of the rotation axis of the cartridge gear 41. The direction of the rotation axis of the cartridge gear 41 may be a vertical direction.

[0204] The inner circumferential protrusion 416 may be inserted into the first guide slit 316 and the second guide slit 326. The inner circumferential protrusion 416 may guide the cartridge 30 to be assembled 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 may contact the inner circumferential protrusion 416 sequentially.

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

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

[0207] When the cigarette cartridge 30 is fully inserted into the receiving space 11, the retaining protrusion 117 (see Fig.12 ) can be assembled into the retaining groove 317, thereby holding the first container 31 in place. When the cigarette cartridge 30 is fully inserted into the receiving space 11, the assembly protrusion 337 can be assembled into the assembly groove 137 (see Figure 6 ), thereby keeping the container head 33 in place. When the cigarette cartridge 30 is fully inserted into the receiving space 11, the inner peripheral protrusion 416 can be positioned 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 peripheral protrusion 416 engages with the second guide slit 326. When the second container 32 rotates, the position of the first container 31 can be maintained. When the second container 32 rotates, the position of the container head 33 and the position of the mouthpiece 34 can be maintained.

[0209] The second guide slit 326 may include a portion that continuously widens when moving downward. The second guide slit 326 may have a maximum width at the lower end of the second container 32. The width w2 of the second guide slit 326 may continuously decrease when moving upward 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 a portion thereof adjacent to the lower end of the second guide slit 326. 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 having the same width as the width of the inner peripheral protrusion 416. The width w1 of the upper portion of the second guide slit 326 may be equal to the width w0 of the inner peripheral protrusion 416 (see Fig.13 ). The width w2 of the lower portion 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 if the cigarette cartridge 30 is inserted into the gear assembly hole 411 when the first guide slit 316 and the second guide slit 326 are not aligned, the inner peripheral 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 with the second guide slit 326.

[0213] Therefore, since the first connection passage 319 is accurately communicated with the lower chamber hole 323, a decrease in aerosol flow efficiency can be prevented.

[0214] Reference Fig.16 and Fig.17 , the cartridge gear 41 may be engaged with the dial gear 42 so as to rotate together with the dial gear 42. The rotation axis of the cartridge gear 41 and the rotation axis of the dial gear 42 may be oriented parallel to each other.

[0215] The first gear teeth 412 may be formed on the outer peripheral surface of the cartridge gear 41. The second gear teeth 422 may be formed on the outer peripheral surface of the dial gear 42. The first gear teeth 412 and the second gear teeth 422 may engage with each other so as to rotate together. The height of the first gear teeth 412 may be equal to the height of the second gear teeth 422. The outer peripheral surface of the dial gear 42 may be referred to as the outward-facing surface of the dial gear 42 or the outer surface of the dial gear 42.

[0216] The dial 43 may be connected to the dial gear 42 so as to rotate together with the dial gear 42. The dial 43 and the dial gear 42 may be coaxially disposed.

[0217] The concavoconvex part 432 may be formed on the outer peripheral surface of the dial 43. The height of the concavoconvex part 432 may be lower than the height of the first gear teeth 412 and the height of the second gear teeth 422. The outer peripheral surface of the dial 43 may be referred to as an outward-facing surface of the dial 43 or an outer surface of the dial 43.

[0218] The user can rotate the dial 43 (see Figure 1 ). When the user rotates the dial 43, the dial gear 42 and the cigarette cartridge gear 41 rotate in sequence, thereby causing the second container 32 to rotate.

[0219] Reference Fig.15 and Fig.18 , the cover 36 can form the bottom surface of the cigarette cartridge 30. The cover 36 can be called a plug 36. The cover 36 can also be called a lower cover 36. The cover 36 can be set below the cylinder 310 (see Figure 4 ). The cover 36 may be coupled or engaged to the cylinder 310. The cover 36 may be fixed to the cylinder 310. By pressing the lower surface of the cover 36 upward, an assembly hole 307 may be formed in the cover 36. The assembly hole 307 may be positioned to be spaced apart from the center of the cover 36. The assembly hole 307 may be spaced apart from an axis extending from the rotation axis of the second container 32. Hereinafter, the assembly hole 307 may be referred to as the assembly hole 307.

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

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

[0222] The fitting protrusion 167 may be configured to have the form of a cylinder extending upward. The upper portion of the fitting protrusion 167 may become narrower as it moves upward. The upper end of the fitting protrusion 167 may be rounded.

[0223] Therefore, the first container 31 and the cigarette cartridge 30 can be set at designated positions.

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

[0225] Therefore, even when the second container 32 is rotated, the first container 31 can be maintained in place.

[0226] The first terminal 164 may protrude upward from the bottom surface 168 of the base 16. The first terminal 164 may be composed of a pair of terminals and may be spaced the same distance from the center of the base 16.

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