The first inclined surface 416a can be inclined toward the central axis of the receiving space 11 as it moves in the direction in which the cartridge 30 is inserted into the receiving space 11. The first inclined surface 416a can be inclined toward the central axis of the receiving space 11 as it moves downward.

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

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

[0198] Accordingly, the cartridge 30 can be easily taken out of the receiving space 11.

[0199] Accordingly, the cartridge 30 can be easily inserted into the gear fitting hole 411.

[0200] Accordingly, the cartridge 30 can be easily taken out of the gear fitting hole 411.

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

[0202] Accordingly, 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 taken out.

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

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

[0205] The first guide slit 316 can include a plurality of first guide slits arranged in a circumferential direction of the cartridge 30. The second guide slit 326 can include a plurality of second guide slits arranged in a circumferential direction of the cartridge 30. The inner circumferential protrusion 416 can include a plurality of inner circumferential protrusions arranged in a circumferential direction of the cartridge gear 41. The plurality of inner circumferential protrusions 416 can be arranged at positions corresponding to the plurality of second guide slits 326. Each of the plurality of inner circumferential protrusions 416 can fit 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 a rotation direction of the second container 32. The circumferential direction of the cartridge gear 41 can be the same as a 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 cartridge 30 is completely inserted into the receiving space 11, the holding protrusion 117 (see Figure 12 ) can fit into the holding groove 317, thereby holding the first container 31 in place. When the cartridge 30 is completely inserted into the receiving space 11, the fitting protrusion 337 can fit into the fitting groove 137 (see Figure 6 ), thereby holding the container head 33 in place. When the cartridge 30 is completely inserted into the receiving space 11, the inner circumferential protrusion 416 can be positioned at an 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 is engaged 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 can include a portion that continuously widens as it moves downward. The second guide slit 326 can have a maximum width at a lower end of the second container 32. The width w2 of the second guide slit 326 can continuously decrease as it moves upward from the lower end, and can maintain a constant value from a predetermined height to the upper end thereof. The width w2 of a lower portion of the second guide slit 326 can be greater than the width w1 of an upper portion of the second guide slit 326.

[0210] The width w3 of the first guide slit 316 can become equal to the width w2 of the lower end of the second guide slit 326 at a portion thereof that adjoins the lower end of the second guide slit 326. The width w3 of the first guide slit 316 can 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 can have a portion having the same width as the width of the inner circumferential protrusion 416. The width w1 of the upper portion of the second guide slit 326 can be equal to the width w0 of the inner circumferential protrusion 416 (see Figure 13 ). The width w2 of the lower portion of the second guide slit 326 can be greater than the width w0 of the inner circumferential protrusion 416. The width w3 of the first guide slit 316 can be greater than the width w0 of the inner circumferential protrusion 416.

[0212] Therefore, even in a state in which the first guide slit 316 and the second guide slit 326 are misaligned, 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 passage 319 precisely communicates with the lower chamber hole 323, a decrease in aerosol flow efficiency can be prevented.

[0214] Referring to Figure 16 and Figure 17 , the cartridge gear 41 can 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 can be oriented to be parallel to each other.

[0215] The first gear teeth 412 can be formed on the outer circumferential surface of the cartridge gear 41. The second gear teeth 422 can be formed on the outer circumferential surface of the dial gear 42. The first gear teeth 412 and the second gear teeth 422 can be engaged with each other so as to rotate together. The height of the first gear teeth 412 can be equal to the height of the second gear teeth 422. The outer circumferential surface of the dial gear 42 can be referred to as an outwardly facing surface of the dial gear 42 or an outer surface of the dial gear 42.

[0216] The dial 43 can 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 can be coaxially disposed.

[0217] The concavo-convex portion 432 can be formed on the outer circumferential surface of the dial 43. The height of the concavo-convex portion 432 can be lower than the height of the first gear teeth 412 and the height of the second gear teeth 422. The outer circumferential surface of the dial 43 can be referred to as an outwardly facing surface of the dial 43 or an outer surface of the dial 43.

[0218] A user can rotate the dial 43 outside the housing 10 (see Figure 1 ). When the user rotates the dial 43, the dial gear 42 and the cartridge gear 41 are sequentially turned, thereby turning the second container 32.

[0219] Referring to Figure 15 andFigure 18 The cover 36 can form a bottom surface of the cartridge 30. The cover 36 can be referred to as a plug 36. The cover 36 can also be referred to as a lower cover 36. The cover 36 can be disposed below the cylinder 310 (see Figure 4 ) The cover 36 can be coupled or joined to the cylinder 310. The cover 36 can be fixed to the cylinder 310. An assembly hole 307 can be formed in the cover 36 by pressing a lower surface of the cover 36 upward. The assembly hole 307 can be positioned to be spaced apart from the center of the cover 36. The assembly hole 307 can be spaced apart from an axis extending from a rotation axis of the second container 32. Hereinafter, the assembly hole 307 can be referred to as an assembly hole 307.

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

[0221] The assembly hole 307 can be positioned at a position corresponding to the assembly protrusion 167. The assembly protrusion 167 can be assembled into the assembly hole 307 when the cartridge 30 is inserted into the reception space 11.

[0222] The assembly protrusion 167 can be configured to have the form of a cylinder extending upward. An upper portion of the assembly protrusion 167 can be narrowed when moving upward. An upper end of the assembly protrusion 167 can be rounded.

[0223] Accordingly, the first container 31 and the cartridge 30 can be disposed at designated positions.

[0224] Accordingly, 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 cartridge to a correct position.

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

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

[0228] The second terminal 304 can be positioned at a position corresponding to the first terminal 164. When the cartridge 30 is inserted into the receiving space 11, the second terminal 304 can come into contact with the first terminal 164, and thus can be electrically connected to the first terminal 164. The first terminal 164 can deliver power to the second terminal 304, so that the heater 314 heats the wick 313.

[0229] In conjunction with Figure 2 Referring to Figure 19 The connector 110 can include a cylindrical connector body 111. The connector body 111 can extend vertically.

[0230] The connector 110 can have a structure configured to maintain a rotational position of the cartridge 30. A holding protrusion 117 can protrude from an inner circumferential surface 112 of the connector 110.
