When the cartridge 40 is attached to the main body 50, the power source may be electrically connected to the cartridge 40. The main body 50 may have a shape that extends elongated in the longitudinal direction of the cartridge.

Figure 3 is a diagram illustrating a stick 10 according to one embodiment of the present disclosure. Referring to Figure 3, the stick 10 may have a cylindrical shape. The stick 10 may be elongated. The cross section of the stick 10 may be circular or polygonal. The stick 10 may include a medium portion 11, a cooling portion 12, a filter portion 13, and a wrapper 14. The medium portion 11, the cooling portion 12, and the filter portion 13 may be arranged consecutively.

The cooling section 12 may be disposed between the medium section 11 and the filter section 13. The wrapper 14 may encase the medium section 11, the cooling section 12, and the filter section 13. The medium section 11 may include a medium 113. The medium section 11 may include a first medium cover 111. The medium section 11 may include a second medium cover 112. The medium 113 may be disposed between the first medium cover 111 and the second medium cover 112. The first medium cover 111 may be disposed at one end of the stick 10. The length of the medium section 11 may be 24 mm.

The medium 113 may contain substances with various components. The substances contained in the medium may be flavoring substances with various components. The medium 113 may emit a fragrance when heated. The medium 113 may be composed of a plurality of granules. Each of the plurality of granules may have a size of 0.4 mm to 1.12 mm. The medium 113 may be filled with granules to approximately 70%. The length L2 of the medium 113 may be 10 mm.

The first medium cover 111 may be made of acetate material. The second medium cover 112 may be made of acetate material. The first medium cover 111 may be made of paper material. The second medium cover 112 may be made of paper material. At least one of the first medium cover 111 and the second medium cover 112 may be made of paper material and may have a wrinkled shape, forming multiple gaps between them for air to flow through. The gaps may be smaller than the size of each granule of the medium 113. The length H1 of the first medium cover 111 may be shorter than the length H2 of the medium 113. The length H3 of the second medium cover 111 may be shorter than the length H2 of the medium 113. The length H1 of the first medium cover 111 may be 7 mm. The length H2 of the second medium cover 111 may be 7 mm.

Therefore, each granule of the medium 113 cannot detach from the medium portion 11 and the stick 10.

The cooling section 12 may have a cylindrical shape. The cooling section 12 may have a hollow shape. The cooling section 12 may be disposed between the medium section 11 and the filter section 13. The cooling section 12 may be disposed between the second medium cover 112 and the filter section 13. The cooling section 12 may be formed in a tubular shape surrounding the internal cooling path 121. The cooling section 12 may be thicker than the wrapper 14. The cooling section 12 may be made of a paper material that is thicker than the wrapper 14. The length H4 of the cooling section 12 may be the same as or approximately the same as the length H2 of the medium 113. The length H4 of the cooling section 12 and the cooling path 121 may be 10 mm. When the stick 10 is inserted into the aerosol generation device (see FIG. 3), at least a portion of the cooling section 12 may be exposed to the outside of the aerosol generation device.

Therefore, the cooling section 12 supports the medium section 11 and the filter section 13, ensuring the rigidity of the stick 10. The cooling section 12 also supports the wrapper 14 between the medium section 11 and the filter section 13, ensuring an area where the wrapper 14 is adhered. Furthermore, the heated air and aerosol can be cooled as they pass through the cooling path 121 inside the cooling section 12.

The filter portion 13 may be made of an acetate filter. The filter portion 13 may be located at the other end of the stick 10. When the stick 10 is inserted into the aerosol generating device (see FIG. 3), the filter portion 13 may be exposed to the outside of the aerosol generating device. A user can inhale air by holding the filter portion 13 in their mouth. The length H5 of the filter portion 13 may be 14 mm.

The wrapper 14 may wrap or surround the medium portion 11, the cooling portion 12, and the filter portion 13. The wrapper 14 may form the outer shape of the stick 10. The wrapper 14 may be made of a paper material. The adhesive portion 143 may be formed on one side edge of the wrapper 14. The wrapper 14 wraps the medium portion 11, the cooling portion 12, and the filter portion 13, and the adhesive portion 143 formed on one side edge and the other side edge may be adhered to each other. The wrapper 14 wrapping the medium portion 11, the cooling portion 12, and the filter portion 13 does not have to cover one end and the other end of the stick 10.

Therefore, the wrapper 14 secures the medium portion 11, cooling portion 12, and filter portion 13, preventing them from coming off the stick 10.

The first thin film 141 may be disposed at a position corresponding to the first medium cover 111. The first thin film 141 may be disposed between the wrapper 14 and the first medium cover 111, or may be disposed outside the wrapper 14. The first thin film 141 may surround the first medium cover 111. The first thin film 141 may be made of a metal material. The first thin film 141 may be made of an aluminum material. The first thin film 141 may be adhered to or coated on the wrapper 14.

The second thin film 142 may be disposed at a position corresponding to the second medium cover 112. The second thin film 142 may be disposed between the wrapper 14 and the second medium cover 112, or may be disposed outside the wrapper 14. The second thin film 142 may be made of a metal material. The second thin film 142 may be made of an aluminum material. The second thin film 142 may be adhered to or coated on the wrapper 14.

Figure 4 is an exploded perspective view showing the coupling relationship between the cartridge 40 and the main body 50. Referring to Figure 4, the cartridge 40 may have a groove 411 formed on its outer surface. The main body 50 may have a protrusion 512 on its outer surface that engages with the groove 411 of the cartridge 40. The cartridge 40 may have a plurality of grooves 411, and the main body 50 may have a plurality of protrusions 512. The main body 50 may have a protrusion 54 formed on its outer surface. The casing 30 may be coupled to the protrusion 54 of the main body 50.

The main body 50 may include a mounting portion 51 to which the cartridge 40 is attached, and an elongated column 52. The mounting portion 51 may be disposed on the outer surface of the main body 50. The column 52 may be connected to the mounting portion 51.

The mounting portion 51 may be recessed into the main body 50 to define a mounting space 513 in which the cartridge 40 is mounted. A protrusion 512 may be formed on the inner surface of the mounting portion 51. A column 52 may be connected to one side of the mounting portion 51.

The column 52 may extend in a direction parallel to the longitudinal direction of the cartridge 40. The column 52 may have a hollow interior. The column 52 may support the cartridge 40 attached to the main body 50. The column 52, together with the attachment portion 51, may form an attachment space 513 in which the cartridge 40 is attached.

The column 52 may include through holes 521 and 522. The through hole 521 may be connected to the outside of the aerosol generation device 1. The through holes 521 and 522 may be connected to each other via the internal space of the column 52. Air outside the aerosol generation device 1 may flow into the interior of the cartridge 40 by sequentially passing through the internal space of the column 52, the through holes 521 and 522, and the inlet 412a (see Figure 5).

Figure 5 is a cross-sectional view of a cartridge 40 stick 10 according to one embodiment of the present disclosure. Referring to Figure 5, the cartridge 40 may include a container 42, a base 41, a wick 43/43, a heater 44, and a stopper 60.

The container 42 may include an insertion space 426 into which the stick 10 is inserted, a long pipe 423 that defines the insertion space 426 inside, an outer wall 422 that surrounds the pipe 423, and a storage space 424 that is formed between the pipe 423 and the outer wall 422 and that stores the aerosol-generating substance 1.

The pipe 423 and outer wall 422 of the container 42 may be formed cylindrically. The pipe 423 may have a predetermined inner diameter D2 and may form an insertion space 426 therein. However, unlike the embodiment of the present disclosure, the pipe 423 may have a cross-section corresponding to the cross-section of the stick 10.

The outer wall 422 may extend longitudinally along the length of the pipe 423. The pipe 423 may be disposed inside the outer wall 422. The pipe 423 and the outer wall 422 may extend parallel to each other. An aerosol-generating substance 1 may be contained between the outer wall 422 and the pipe 423, which vaporizes and/or atomizes to form an aerosol.

The pipe 423 and outer wall 422 of the container 42 may be made of a translucent or transparent material. An insertion space 426 may be disposed inside the pipe 423. Because the insertion space 426 is located inside the pipe 423, the aerosol generation device 1 can be made more compact than if the insertion space 426 were provided outside the container 42.

Meanwhile, the aerosol-generating substance l may be in a liquid state or a gel state at room temperature. The aerosol-generating substance l can be vaporized and/or atomized when heated. The aerosol-generating substance l can be referred to as a liquid-type or gel-type substance.

The insertion space 426 can be in communication with the outside of the cartridge 40 via an opening 425 provided at one end 427 of the pipe 423 of the container 42. The insertion space 426 of the pipe 423 can be formed in a cylindrical shape. The generated aerosol can flow to the outside of the cartridge 40 through the insertion space 426 and the opening 425.

The base 41 may be positioned adjacent to the other end 428 of the container 42. The base 41 may be positioned adjacent to the wick 4343. The base 41 may include a bottom 413, a sidewall 412, and an interior space 414.

The bottom 413 of the base 41 may face the insertion space 426 relative to the wick 43. The bottom 413 of the base 41 may face the opening 425. The sidewalls 412 of the base 41 may extend from the bottom 413 toward the container 42. The sidewalls 412 of the base 41 may be connected to the container 42. The heater 44 may be electrically connected to the power source of the main body 50 via the bottom 413 of the base 41. An inlet 412a may be formed in the sidewalls 412 of the base 41.

The inlet 412a can penetrate the side wall 412 of the base 41. The inlet 412a can open in a direction perpendicular to the side wall 412 of the base 41. The inlet 412a can communicate with the through hole 522. The inlet 412a can face the through hole 522. Air flowing in through the inlet 412a can flow into the wick 4343. The inlet 412a can be formed between the container 42 and the bottom 413 of the base 41 in the longitudinal direction of the container 42. The inlet 412a can be positioned closer to the container 42 than the bottom 413 of the base 41.

The internal space 414 of the base 41 may be in communication with the periphery of the wick 4343 and the insertion space 426. Liquefied aerosol may be retained in the internal space 414. A flow path may be formed in the internal space 414 of the base 41, connecting the periphery of the wick 43 to the outside of the cartridge 40.

Portions 432, 433 of the wick 43 may be connected to the interior 424 of the container 42. Portions 432, 433 of the wick 43 may be located in the interior 424 of the container 42 and connected to the liquid l contained between the pipe 423 and the outer wall 422. The wick 43 may be partially inserted into the containing space 424. The wick 43 may pass through the pipe 423 of the container 42 and be connected to the containing space 424. The wick 43 may be positioned between one end 427 and the other end 428 of the pipe 423. The wick 43 may be positioned between the stopper 60 and the other end 428 of the pipe 423. The wick 43 can absorb the liquid l contained in the containing space 424.

The core 43 may be elongated. The core 43 may have one end 432 and the other end 433 that extend elongated. The core 43 may include an outer surface 431 that extends elongatedly and connects the one end 432 and the other end 433. The outer surface 431 of the core 43 may be referred to as the peripheral surface 431. Alternatively, the core 43 may be formed in a cylindrical shape. The outer surface 431 of a cylindrical core 43 may be referred to as the outer circumferential surface 431.

The heater 44 may be disposed around the core 43. The heater 44 may surround the core 43. For example, the heater 44 may be formed from a long wire. The heater 44 may be wrapped around the core 43 several times.

The heater 44 generates heat to vaporize and/or atomize the liquid absorbed in the wick 43. The heater 44 can be electrically connected to the power source of the main body 50 via the base 41.

The aerosol generating device 1 according to one embodiment of the present disclosure may include a stopper 60. The stopper 60 may protrude from the inner surface of the pipe 423. A plurality of stoppers 60 may be arranged. The plurality of stoppers 60 may define a single support surface P. The stick 10 may be inserted into the insertion space 426 through the opening 425 and supported by the stopper 60. The stick may be placed on the support surface P. The stopper 60 may limit the movement of the inserted stick 10.

The stoppers 60 may protrude from the inner surface of the pipe 423 toward the insertion space 426. The stoppers 60 may narrow the inner diameter D2 of the pipe 423. In the diameter direction of the pipe 423, the distance D1 between the stoppers 60 may be smaller than the inner diameter D2 of the pipe 423. The diameter of the stick 10 inserted into the insertion space 426 may be larger than the distance D1 between the stoppers 60 and smaller than the inner diameter D2 of the pipe 423. Therefore, the stoppers 60 can prevent the stick 10 from being inserted too far into the insertion space 426.

On the other hand, the distance D1 between the stoppers 60 may be greater than the length of the portion of the outer surface 431 of the wick 43 that is surrounded by the heater 44. Since a large amount of aerosol is generated from the portion of the outer surface 431 of the wick 43 that is wrapped around the heater 44, the generated aerosol can flow toward the first medium cover 111 of the stick 10 without being restricted in flow by the stoppers 60.

The support surface P defined by the stopper 60 may extend in a direction intersecting the longitudinal direction of the pipe 423. For example, the support surface P may extend in a direction perpendicular to the longitudinal direction of the pipe 423. The core 43 may extend in a direction intersecting the longitudinal direction of the pipe 423. For example, the core 43 may extend in a direction perpendicular to the longitudinal direction of the pipe 423.

The liquid 1 absorbed in the wick 43 can be atomized and/or vaporized as an aerosol by the heater 44 and diffused around the wick 43. The heater 44 can provide heat to the surrounding area. The end of the stick 10 that is inserted and in contact with the stopper 60 can receive heat from the diffused aerosol and the heater 44.

On the other hand, as the distance G between one end of the stick 10 and the outer surface 431 of the wick 43 increases, the amount of heat provided to one end of the stick 10 from the generated aerosol and heater 44 decreases, which may result in insufficient heat being provided to the medium 113. As the distance G between one end of the stick 10 and the outer surface 431 of the wick 43 decreases, the amount of heat provided to one end of the stick 10 from the generated aerosol and heater 44 increases, which may cause the one end of the stick 10 supported by the stopper 60 to ignite or the first medium cover 111 to melt, releasing harmful substances. Here, the distance G may be the shortest distance between the support surface P and the outer surface 431 of the wick 43.

Therefore, it is necessary to set the optimal separation distance G. The separation distance G can be between 3 mm and 8 mm. The separation distance G can be changed by a predetermined value based on the amount of power supplied to the heater 44, the amount of liquid 1 absorbed in the wick 43, etc.

Figure 6 is an enlarged view of a portion of Figure 5. Referring to Figures 5 and 6, the stopper 60 may include a support surface 61, a connecting surface 62, and a collision surface 63.

The support surface 61 can support the stick 10. The support surfaces 61 of multiple stoppers 60 can define a single support surface P. The support surface 61 can be formed flat. The support surface 61 can extend in a direction intersecting the longitudinal direction of the pipe 423. For example, the support surface 61 can extend in a direction perpendicular to the longitudinal direction of the pipe 423.

The impact surface 63 may be positioned closer to the wick 43 than the support surface 61. The impact surface 63 may face the outer surface 431 of the wick 43. The stopper 60 may prevent a portion a of the aerosol generated by the heater 44 and flowing toward the stick 10 from reaching the stick 10.

The connecting surface 62 can connect the support surface 61 and the impact surface 63. The connecting surface 62 of any one of the multiple stoppers 60 can face another connecting surface 62. In the diameter direction of the pipe 423, the distance between the connecting surfaces 62 of the opposing stoppers 60 can be the distance D1 between the stoppers 60.

Figure 7 is an enlarged view of a portion of Figure 5, showing a stopper 160 of a different embodiment from the embodiment of the present disclosure shown in Figure 6. Referring to Figures 5 to 7, the stopper 160 may include a support surface 161 and a collision surface 162.

The support surface 161 can support the stick 10. The support surfaces 161 of multiple stoppers 160 can define a single support surface P. The support surface 161 can be formed flat. The support surface 161 can extend in a direction intersecting the longitudinal direction of the pipe 423. For example, the support surface 161 can extend in a direction perpendicular to the longitudinal direction of the pipe 423.

The collision surface 162 may be positioned closer to the wick 43 than the support surface 161. The collision surface 162 may connect the inner end 1622 of the support surface 161 to a portion 1621 of the inner surface of the pipe 423. The collision surface 162 may be formed obliquely from the inner surface of the pipe 423 to the inside of the pipe 423. The collision surface 162 may face the wick 43. A portion a' of the aerosol generated by the heater 44 and flowing toward the stick 10 may be guided by the collision surface 162 to reach the stick 10.

FIG. 8 shows a stopper 260 according to one embodiment of the present disclosure. Referring to FIG. 8, the stopper 260 may be elongated. The stopper 260 may be formed in a ring shape on the inner surface of the pipe 423. The stopper 260 may extend in the circumferential direction of the pipe 423. The stopper 260 may include a support surface 261, a connecting surface 262, and a collision surface (not shown).

The support surface 261 can support the stick 10 inserted into the insertion space 426. The support surface 261 can extend in a direction intersecting the longitudinal direction of the pipe 423. For example, the support surface 261 can extend in a direction perpendicular to the longitudinal direction of the pipe 423.

Meanwhile, the ring-shaped stopper 260 can support the wrapper 14 surrounding the stick 10. This prevents the aerosol generated by the wick 43 and the heat provided by the heater 44 from being directly transferred to the wrapper 14, thereby preventing the wrapper 14 from overheating and emitting harmful substances.

Figure 9 shows a stopper 360 according to one embodiment of the present disclosure. Referring to Figure 9, a plurality of stoppers 360 may be arranged. The plurality of stoppers 360 may be arranged consecutively on the inner surface of the pipe 423. A flow path through which the aerosol generated in the wick 43 flows may be formed between adjacent stoppers 360. The stopper 360 may include a support surface 361, a connecting surface 362, and a collision surface 363.

The support surface 361 can support the stick 10. The support surface 361 can be formed flat. The support surface 361 can extend in a direction that intersects with the longitudinal direction of the pipe 423. For example, the support surface 361 can extend in a direction perpendicular to the longitudinal direction of the pipe 423.

The impact surface 363 may be positioned closer to the wick 43 than the support surface 361. The impact surface 363 may face the outer surface 431 of the wick 43. A portion of the aerosol generated by the heater 44 and flowing toward the stick 10 may impact the impact surface 363. The connecting surface 362 may connect the support surface 361 and the impact surface 363.

The multiple stoppers 360 can be arranged symmetrically about the central axis CL of the pipe 423. The multiple stoppers 360 can be arranged at equal intervals in the circumferential direction of the pipe 423. The multiple stoppers 360 can support the stick 10.

Figures 10 and 11 show a portion of an aerosol generating device according to one embodiment of the present disclosure. Referring to Figures 10 and 11, the aerosol generating device may include a container 42' including an elongated pipe 423' into which the stick 10 is inserted, and an outer wall 422' surrounding the pipe 423' to form a storage space 424' between the pipe 423' and the container 422'.

The stick 10 can be inserted into the inside of the pipe 423' through one end 427' of the pipe 423'. The stick 10 can be supported by a stopper 60' protruding from the inner surface of the pipe 423'. The stopper 60' can be positioned adjacent to the other end 428 of the pipe 423'. Multiple stoppers 60' can be formed.

The aerosol generating device may include a base 41' connected to the container 42' and whose interior is in communication with the interior of the pipe 423'.
