The first extension 362 may extend upward from the bottom 361 of the plug 36 to surround the first suction port 301. The first extension 362 may form a step with respect to the bottom 361 of the plug 36.

Therefore, even if the pre-vaporized formulation leaks from the liquid chamber 311, it can be prevented from flowing out of the cartridge 30 through the first intake port 301.

The connecting portion 365 may extend upward from the outer periphery of the plug 36. The connecting portion 365 may extend in the circumferential direction. The connecting portion 365 may be fitted to the inner periphery of the lower portion of the cylinder 310.

The outer peripheral surfaces of the upper rim 375 and the lower rim 377 may form a continuous surface. The upper rim 375 and the lower rim 377 may contact the inner peripheral surface of the cylinder 310.

Below, with reference to Figures 3 and 4, we will explain the flow of air and aerosol when a user inhales air through the mouthpiece 34.

When a user inhales air through the mouthpiece 34, the air can flow in from the outside of the housing 10 and pass through the storage space 11 between the housing 10 and the cartridge 30. The air that has passed between the storage space 11 and the cartridge 30 can flow into the evaporation chamber 312 inside the first container 31 through the first inlet 301. The air that has flowed in can pass through the evaporation flow path 318 together with the aerosol in the evaporation chamber 312. The aerosol that has passed through the evaporation flow path 318 can flow into the second granule chamber 322 through the first connection flow path 319 and the lower chamber hole 323 in sequence. The aerosol can pass through the medium inside the second granule chamber 322 and pass through the upper chamber hole 324 and the first outlet 302 in sequence. The aerosol that has passed through the first outlet 302 can flow into the second inlet 341, pass through the inlet flow path 343, and be discharged upward through the second outlet 342.

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 guide the cartridge 30 in the vertical direction along the inner peripheral protrusion 416. When the cartridge 30 is inserted into the storage space 11, the inner peripheral protrusion 416 may engage with the upper end of the second guide slit 326. The upper end of the second guide slit 326 may function as a stopper that prevents the cartridge 30 from moving further downward.

The first guide slit 316 can extend in the longitudinal direction of the second guide slit 326. The first guide slit 316 and the second guide slit 326 form a continuous surface, and can guide the cartridge 30 in the vertical direction along the inner peripheral protrusion 416.

The mouthpiece 34 can be pivotally connected or coupled to the container head 33. FIG. 5 shows the mouthpiece 34 pivoted to a first position, and FIG. 6 shows the mouthpiece 34 pivoted to a second position.

Below, with reference to Figure 5, we will explain the case where the mouthpiece 34 pivots to the first position.

When the mouthpiece 34 pivots and is positioned in the first position, the mouthpiece 34 can be seated on the seating portion 14. The mouthpiece 34 can close the upper part of the housing 10. The mouthpiece 34 can close the opening O of the upper case 20. One side of the mouthpiece 34 can be exposed to the outside through the opening O.

The sealing cap 35 may protrude downward from the mouthpiece 34. The sealing cap 35 may have a hook shape. The sealing cap 35 may close the first outlet 302.

Therefore, the medium contained within the cartridge, the pre-vaporized formulation, and the internal structure can be protected from the external environment.

The sealing cap 35 can have an outer surface that is rounded in the pivot direction of the mouthpiece 34. This allows the mouthpiece 34 to pivot to the first position without the sealing cap 35 touching the surface formed around the first outlet 302.

Below, with reference to Figure 6, we will explain the case where the mouthpiece 34 pivots to the second position.

When the mouthpiece 34 pivots to the second position, the mouthpiece 34 can be removed from the seat 14. The sealing cap 35 can be removed from the first outlet 302 to open the first outlet 302.

The first outlet 302 and the second inlet 341 can be in contact with each other. The inlet passage 343 of the mouthpiece 34 can be in communication with the first outlet 302. The inlet passage 343 of the mouthpiece 34 can be in communication with the internal spaces of the first container 31 and the second container 32 via the first outlet 302.

The intake passage 343 may be arranged to extend in the longitudinal direction of the cartridge 30. The intake passage 343 may be arranged to extend in the vertical direction. The sealing cap 35 may be arranged to protrude toward the seating portion 14.

The directions of the mouthpiece 34 are defined below based on the Cartesian coordinate system shown in Figures 7 to 9. The FD (Forward Direction) direction of the coordinate system can be defined as the front direction of the mouthpiece 34. The RD (Rear Direction) direction can be defined as the rear direction of the mouthpiece 34. The LD (Lateral Direction) direction can be defined as the left/right direction or side direction of the mouthpiece 34. The UD (Upward Direction) direction can be defined as the upper direction of the mouthpiece 34. The DD (Downward Direction) direction can be defined as the lower direction of the mouthpiece 34.

Referring to FIG. 7 and FIG. 8, the mouthpiece 34 may have a long shape in the front-rear direction of the mouthpiece 34. The mouthpiece 34 may have a flat shape. The second inlet (or inlet) 341 may be formed at the rear of the mouthpiece 34. The second outlet 342 may be formed at the front of the mouthpiece 34.

The flow path 343 (see FIG. 6) may be formed inside the mouthpiece 34 and extend in the front-rear direction. The second intake port 341 may be located at one end of the flow path 343. The second exhaust port 342 may be located at the other end of the flow path 343. The distance from the pivot shaft 355 of the mouthpiece 34 to the second exhaust port 342 may be longer than the distance from the pivot shaft 355 to the second intake port 341. The flow path 343 may be referred to as the second flow path 343.

Therefore, the user can inhale air by holding the second outlet 342 side of the mouthpiece 34 in their mouth.

The detachable groove 347 may be formed by recessing the side of the mouthpiece 34. The detachable groove 347 may be formed on both sides of the mouthpiece 34. The detachable groove 347 may be located closer to the second outlet 342 than the second inlet 341.

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

The mouthpiece 34 may pivot about the pivot shaft 355. The pivot shaft 355 may be the center of the pivot direction of the mouthpiece 34, or the pivot center. The pivot shaft 355 may protrude in the left-right direction from both sides of the mouthpiece 34 or the sealing cap 35. The pivot shaft 355 may be disposed in a direction perpendicular to the up-down direction. The pivot shaft 355 may be located closer to the second inlet 341 than the second outlet 342.

The sealing cap 35 may include an extension 352 extending below the mouthpiece 34. The sealing cap 35 may include a first sealing surface 356 extending from the lower end of the extension 352 to the rear of the mouthpiece 34. The first sealing surface 356 may form an outer surface at the lower end of the sealing cap 35.

The first sealing surface 356 may contact the periphery of the first outlet 302 when the mouthpiece 34 pivots. When the mouthpiece 34 is in the first position, the first sealing surface 356 may be disposed above the first outlet 302 to close the first outlet 302 (see FIG. 5). When the mouthpiece 34 is in the first position, the first sealing surface 356 may be in close contact with a gasket 331 (see FIG. 11) disposed around the first outlet 302. The gasket 331 may be referred to as a docking member or a docking ring.

The first sealing surface 356 may include a portion that extends in a round shape along the pivot direction of the mouthpiece 34. The first sealing surface 356 may include a first flat portion 356a that is formed flat, and a first round portion 356b that is formed in a round shape along the pivot direction of the mouthpiece 34.

The first flat portion 356a may form the lower surface of the extension portion 352. The first round portion 346b may form a surface that extends in a rounded shape from the first flat portion 356a toward the second inlet 341. The first round portion 356b may form the center of the radius of curvature at a position adjacent to the center of the mouthpiece 34 in the pivot direction.

Therefore, when the mouthpiece 34 pivots, the first sealing surface 356 of the sealing cap 35 does not come into contact with the surface formed around the first outlet 302, and the mouthpiece 34 can smoothly pivot to the first and second positions. The first sealing surface 356 and/or the end of the sealing cap 35 can be spaced apart from the lower surface of the mouthpiece 34 to form a space S between the mouthpiece 34. The front and bottom of the space S can be surrounded by the extension 352 and the first sealing surface 356. The extension 352 and the first sealing surface 346 of the sealing cap 35 can form a hook-shaped cross section.

The sealing cap 35 can be made of an elastic material. For example, the sealing cap 35 can be made of a plastic material.

Therefore, when the mouthpiece 34 is located in the first position, the first sealing surface 356 comes into contact with the first outlet 302 and can press the first outlet 302 while being pushed in the direction in which the space S is formed.

The mouthpiece 34 may include a second sealing surface 346 that defines a rear surface of the mouthpiece and surrounds the second inlet 341. The second sealing surface 346 may form an outer surface of the mouthpiece 34 around the second inlet 341.

The second sealing surface 346 can contact the periphery of the first outlet 302 when the mouthpiece 34 pivots. When the mouthpiece 34 is in the second position, the second sealing surface 346 is disposed to surround the first outlet 302, and the second intake port 341 can communicate with the first outlet 302 (see FIG. 6). When the mouthpiece 34 is in the second position, the second sealing surface 346 can be in close contact with the gasket 331 (see FIG. 11) disposed around the first outlet 302.

The second sealing surface 346 may include a portion that extends in a round shape along the pivot direction of the mouthpiece 34. The second sealing surface 346 may include a second flat portion 346a that is formed flat, and a second round portion 346b that is formed in a round shape along the pivot direction of the mouthpiece 34. The second flat portion 346a may be formed above the second round portion 346b.

The second round portion 346b may form a rounded surface extending along the pivot direction of the mouthpiece 34. The second round portion 346b may have a predetermined curvature. The center of the radius of curvature of the second round portion 346b may be located adjacent to the center of the pivot direction of the mouthpiece 34. The second flat portion 346a may form a flat surface extending from the second round portion 346b toward the upper side of the mouthpiece 34.

Therefore, when the mouthpiece 34 pivots, the second sealing surface 346 of the mouthpiece 34 does not come into contact with the surface formed around the first outlet 302, and the mouthpiece 34 can pivot smoothly between the first and second positions.

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 cap 35. A portion of the spring 344 may be exposed downward from the mouthpiece 34.
