[0025] The user can inhale the aerosol generated in the aerosol generating device 1 by holding the upper housing 30 and the lower housing 70 through the rod 10 inserted into the aerosol generating device 1.

[0026] Figure 2 This is an exploded perspective view of rod 10 according to an embodiment of the present disclosure. (Refer to...) Figure 1 and Figure 2 The rod 10 may include a medium portion 11. The rod 10 may include a cooling portion 12. The rod 10 may include a filtering portion 14. The cooling portion 12 may be disposed between the medium portion 11 and the filtering portion 14. The rod 10 may include a covering 13. The covering 13 may cover the medium portion 11. The covering 13 may cover the cooling portion 12. The covering 13 may cover the filtering portion 14. The rod 10 may have a cylindrical shape.

[0027] The medium portion 11 may include a medium 110. The medium portion 11 may include a first medium cover 111. The medium portion 11 may include a second medium cover 112. The medium 110 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 rod 10. The medium portion 11 may have a length of 24 mm.

[0028] Medium 110 may contain a multi-component substance. The substance contained in the medium may be a multi-component flavoring substance. Medium 110 may consist of multiple particles. Each of the multiple particles may have a size from 0.4 mm to 1.12 mm. The particles may occupy approximately 70% of the volume of medium 110. The length L2 of medium 110 may be 10 mm. A first medium cover 111 may be made of an acetate material. A second medium cover 112 may be made of an acetate material. The first medium cover 111 may be made of a paper material. The second medium cover 112 may be made of a paper material. At least one of the first medium cover 111 or the second medium cover 112 may be made of a paper material and may be wrinkled to form folds, and may form multiple gaps between the folds to allow air to flow through. Each gap may be smaller than each particle of medium 110. The length L1 of the first medium cover 111 may be shorter than the length L2 of medium 110. The length L3 of the second medium cover 112 may be shorter than the length L2 of medium 110. The length L1 of the first medium cover 111 may be 7 mm. The length L3 of the second medium cover 112 can be 7mm.

[0029] Therefore, it is possible to prevent each particle of the medium 110 from separating from the medium portion 11 and the rod 10.

[0030] 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 14. The cooling section 12 may be formed as a tube surrounding the cooling path 120 formed therein.

The length L4 of the cooling section 12 may be equal to or similar to the length L2 of the medium 110. The length L4 of each of the cooling section 12 and the cooling path 120 may be 10 mm. When the rod 10 is inserted into the aerosol generating device, at least a portion of the cooling section 12 may be exposed to the outside of the aerosol generating device.

[0031] Therefore, the cooling section 12 can support the media section 11 and the filter section 14, and can ensure the rigidity of the rod 10. Furthermore, the cooling section 12 can support the wrapping material 13 between the media section 11 and the filter section 14, and can provide the portion to which the wrapping material 13 is adhered.

The user can inhale air while holding the filter section 14 in their mouth. The length L5 of the filter section 14 may be 14 mm.

[0033] The wrapping material 13 may wrap around or surround the medium portion 11, the cooling portion 12, and the filtering portion 14. The wrapping material 13 may form the appearance of the rod 10. The wrapping material 13 may be made of paper material. An adhesive portion 130 may be formed along one edge of the wrapping material 13. The wrapping material 13 may surround the medium portion 11, the cooling portion 12, and the filtering portion 14, and the adhesive portion 130 formed along one edge of the wrapping material 13 and its other edge may adhere to each other. The wrapping material 13 that wraps the medium portion 11, the cooling portion 12, and the filtering portion 14 may not cover one end or the other end of the rod 10.

[0034] Therefore, the wrapping material 13 can secure the medium portion 11, the cooling portion 12, and the filter portion 14, and can prevent these components from separating from the rod 10.

[0035] The first film 131 may be disposed at a position corresponding to the first medium cover 111.

The rod 10, inserted into the aerosol generating device 1 via the cap 20, can be inserted into the insertion space 60.

[0041] The insertion space 60 may be defined by a portion of the outer wall 41 corresponding to the side surface of the cylinder and a portion of the outer wall 511 corresponding to the side surface of the column 51. The insertion space 60 may be located outside the cylinder 40. The insertion space 60 may be located outside the column 51. The portion of the outer wall 41 corresponding to the side surface of the cylinder and the portion of the outer wall 511 corresponding to the side surface of the column 51 may face the insertion space 60.

[0044] The containment space 42 can contain the liquid used to generate the aerosol. The containment space 42 can be defined by the outer wall 41 of the cylinder 40. The containment space 42 can be formed in the cylinder 40.

[0045] A stop 411 may protrude from the outer wall 41 of the cylinder 40. The stop 411 may protrude toward the insertion space 60. The stop 411 may support the rod 10 inserted into the insertion space 60. Multiple stops 411 may be formed on the outer wall 41 of the cylinder 40. The upper surface of the stop 411 may be flat. The flat upper surface of the stop 411 may support the lower surface of the rod 10. A portion of the outer wall 41 of the cylinder 40 may support a portion of the side surface of the rod 10 inserted into the insertion space 60.

[0046] Figure 5 and Figure 6 This is an exploded perspective view of a portion of an aerosol generating apparatus 1 according to an embodiment of the present disclosure. (Refer to...) Figure 5 and Figure 6 The aerosol generating device 1 may include a window 513, a plate 514, a printed circuit board (PCB) 515, a light source 516, a sensor 517, a mounting space 518, and a connector 519.

[0047] Window 513 can cover the interior of column 51. Window 513 can extend longitudinally along column 51. Window 513 can be formed of a light-transmitting material.

Window 513 can be attached to the outer wall of column 51.

[0048] Window 513 provides an insertion space 60. Since window 513 is inserted between insertion space 60 and mounting space 518 where sensor 517 is mounted, the recognition rate and reliability of sensor 517 can be improved compared to cases where other additional components are inserted between insertion space 60 and mounting space 518.

[0049] Board 514 can be disposed in mounting space 518. Board 514 can cover PCB 515. Multiple recesses 510 can be formed in board 514. Light source 516 can be located in each of the multiple recesses 510 in board 514. Board 514 can cover sensor 517. Board 514 can also leave light source 516 uncovered. That is, board 514 can cover sensor 517 while avoiding interference with light source 516. Board 514 can extend in the longitudinal direction of post 51.

[0050] Board 514 can be formed of a translucent material. Board 514 can also be formed of a material that blocks visible light and transmits electromagnetic waves. That is, board 514 can protect PCB 515 and sensor 517, and can not block light from light source 516.

[0051] PCB 515 can be mounted in mounting space 518 within post 51. PCB 515 can be a flexible printed circuit board (FPCB). PCB 515 can extend in the longitudinal direction of post 51. PCB 515 can be connected to light source 516 and sensor 517. PCB 515 can be connected to a battery (not shown) via connector 519. The battery can be located in lower housing 70.

[0052] The light source 516 can be mounted on the PCB 515. Multiple light sources 516 can be installed. The light source 516 can illuminate the cylinder 40. The light illuminating the cylinder 40, which is formed of a light-transmitting material, can be propagated to the outside of the aerosol generating device 1 through the cylinder 40 and the upper housing 30. Therefore, the user can use the light from the light source 516 to check the amount of liquid remaining in the cylinder 40 without disassembling the aerosol generating device 1.

[0053] Sensor 517 can be mounted on PCB 515. Sensor 517 can be positioned facing the insertion space 60. Sensor 517 can sense changes in the electromagnetic properties around sensor 517. When rod 10 is inserted into insertion space 60, the electromagnetic properties around sensor 517 are changed by the first thin film 131 and the second thin film 132 of rod 10, thereby sensor 517 senses the insertion of rod 10.

[0054] The mounting space 518 may be located within the column 51. The mounting space 518 may be defined by the outer wall 511 and window 513 of the column 51.

[0056] Figure 7 This is a cross-sectional view of an aerosol generating apparatus 1 according to an embodiment of the present disclosure. (Refer to...) Figure 7 The aerosol generating device 1 may include a heater 81, a core 82, and stops 513a and 411.

[0057] Heater 81 may be located within cylinder 40. Heater 81 may be positioned near core 82. Heater 81 may receive power from a battery to generate heat. Heater 81 may apply heat to core 82. Heater 81 may be configured to wrap around core 82. Heater 81 may be located in the lower part of cylinder 40. Heater 81 may be located outside cylinder 40, or only a portion of heater 81 may be located inside cylinder 40.

[0058] The core 82 may be located within the cylinder 40. A portion of the core 82 may be connected to the receiving space 42 within the cylinder 40. The core 82 may absorb liquid contained in the receiving space 42. The core 82 may be elongated. The core 82 may be located in the lower part of the cylinder 40. The core 82 may communicate with the insertion space 60. The core 82 may be spaced apart from the insertion space 60 in the radial direction.

[0059] A portion of the outer wall 511 of the column 51 may include a stop 511a. The window 513 may include a stop 513a. Stops 511a and 513a may protrude toward the cylinder 40. Stops 511a and 513a may protrude toward the insertion space 60. Stops 511a and 513a may support the rod 10 inserted into the insertion space 60. Stops 511a and 513a may limit the degree of insertion of the rod 10. Multiple stops 511a and 513a may be formed.

[0060] The stop 411 may protrude from a portion of the outer wall 41 of the cylinder 40. The stop 411 may protrude toward the post 51. The stop 411 may protrude toward the insertion space 60. The stop 411 may support the rod 10 inserted into the insertion space 60. The stop 411 may limit the insertion depth of the rod 10. Multiple stops 411 may be formed. The stops 511a and 513a formed at the post 51 and the stop 411 formed at the cylinder 40 may face each other.

[0061] The portion of the outer wall 41 of the cylinder 40 that defines the insertion space 60 may be inclined so as to gradually approach the column 51 from its upper side to its lower side. The portion of the outer wall 511 of the column 51 that defines the insertion space 60 may be inclined so as to gradually approach the cylinder 40 from its upper side to its lower side. That is, portions of the outer wall 41 of the cylinder 40 and portions of the outer wall 511 of the column 51 may be inclined so as to gradually approach each other in the direction of approaching the interior of the aerosol generating device 1.

[0062] Therefore, the cross-sectional area of ​​the insertion space 60 can gradually decrease from its upper side to its lower side. The dimension D1 of the upper part of the insertion space 60 can be larger than the dimension D2 of the lower part of the insertion space 60. When the rod 10 is inserted into the insertion space 60, the rod 10 can be in close contact with the lower part of the insertion space 60, and a portion of the outer wall 41 of the cylinder 40 and a portion of the outer wall 511 of the column 51 can support the side surface of the rod 10.

[0063] Figure 8 This is a schematic diagram of an aerosol generating apparatus 1 according to an embodiment of the present disclosure. Figure 8 The illustration shows a case where the insertion space 60 is defined by a portion of the outer wall 41 of the cylinder 40 and a portion of the outer wall 511 of the column 51 or the window 513.

[0064] Reference Figure 8 The aerosol generating device 1 may include a contact portion 45, a sensing unit 53, and a central portion 61 of an insertion space 60.

[0065] The contact portion 45 can be in close contact with the outer wall of the column 51. The contact portion 45 can be located outside the insertion space 60. The contact portion 45 can close the insertion space 60. The insertion space 60 can be defined by a portion of the outer wall 41 of the cylinder 40, a portion of the outer wall 511 of the column 51, and the contact portion 45. Since the two contact portions 45 are formed by the cylinder 40 and the column 51, the insertion space 60 can be easily sealed.

[0066] The sensing unit 53 can be installed in the mounting space 518. The sensing unit 53 may include a board 514, a PCB 515, a light source 516, and a sensor 517 disposed in the mounting space 518. The sensing unit 53 can sense whether the rod 10 is inserted into the insertion space 60.

[0067] The central portion 61 of the insertion space 60 may be adjacent to the outer wall 41 of the cylinder 40. The central portion 61 of the insertion space 60 may be adjacent to the receiving space 42 in the cylinder 40. The central portion 61 of the insertion space 60 may be located outside the column 51. Therefore, the size of the installation space 518 can be minimized, and thus the size of the aerosol generating device 1 can be reduced.

[0068] Figure 9 This is a schematic diagram of a portion of an aerosol generating apparatus 100 according to another embodiment of the present disclosure. Figure 9 The illustration shows a case where the insertion space 160 is defined by a portion of the outer wall 141 of the cylinder 140 and a portion of the outer wall 1511 of the column 151.

[0069] Reference Figure 9 The central portion 161 of the insertion space 160 may be adjacent to the mounting space 1518. The central portion 161 of the insertion space 160 may be adjacent to the sensing unit 53 mounted in the post 151. The cylinder 140 may include a contact portion 145 adjacent to the post 151. The central portion 161 of the insertion space 160 may be located outside the cylinder 140. Therefore, the capacity of the cylinder 140 can be increased.

[0070] The heater 81 and the core 82 may be located below the insertion space 160. When the heater 81 applies heat to the liquid-impregnated core 82, the liquid can evaporate to generate an aerosol, and the aerosol can rise into the insertion space 160. After the insertion rod 10 is inserted, the user can operate the heater 81 to draw in the aerosol through the rod 10.

[0071] Figure 10 This is a schematic diagram of a portion of an aerosol generating apparatus 200 according to another embodiment of the present disclosure. Figure 10 The illustration shows a case where the insertion space 260 is defined by a portion of the outer wall 241 of the cylinder 240, a portion of the outer wall 2511 of the column 251, and a portion of the inner wall of the upper housing 30.

[0072] Reference Figure 10 A portion of the outer wall 241 of the cylinder 240 and a portion of the outer wall 2511 of the column 251 may define an insertion space 260. The portions of the outer wall 241 of the cylinder 240 and the portions of the outer wall 2511 of the column 251 may be spaced apart from each other. A portion of the inner wall of the upper housing 30 may define the insertion space 260. The insertion space 260 may also be defined by another component (not shown) when it is attached to the inner wall of the upper housing 30.

[0073] Figure 11 This is a schematic diagram of a portion of an aerosol generating apparatus 300 according to another embodiment of the present disclosure. Figure 11 The example shows a slit 43 formed in a portion of the outer wall 3511 of the column 351 or in the window 3513.

[0074] See Figure 11 The slit 43 may be formed in a portion of the outer wall 3511 of the column 351 or in the window 3513. The slit 43 may extend in the longitudinal direction of the column 351. Air may flow into the slit 43. The slit 43 may communicate with the insertion space 360. When the rod 10 is inserted into the insertion space 360, the rod 10 may contact the slit 43. The slit 43 may communicate with the outside of the aerosol generating device 300. The slit 43 may communicate with the hole formed in the cap 20. Air outside the aerosol generating device 300 may flow into the insertion space 360 ​​through the slit 43. The slit 43 may allow the hole and the lower side of the insertion space 360 ​​to communicate with each other through it.

[0075] The heater 81 and the core 82 may be located below the insertion space 360. When the heater 81 applies heat to the liquid-impregnated core 82, the liquid can evaporate to generate an aerosol, and the aerosol can rise into the insertion space 360. After the insertion rod 10 is inserted, the user can operate the heater 81 to draw in the aerosol through the rod 10.

[0076] When the user inserts the rod 10 into the aerosol generating device 300 and then draws the rod 10 in, air outside the aerosol generating device 300 can flow through the slit 43 to the periphery of the core 82, and air and vapor generated by the evaporation of liquid by the heater 81 can pass through the rod 10 and be inhaled by the user.
