[0024] A singular expression includes plural expressions unless explicitly indicated otherwise in the context.

[0025] Referring to Figure 1, the aerosol generator can include a body 10 and cartridges 20 and 30. The cartridges 20 and 30 can include a first container 20 and a second container 30. The cartridges 20 and 30 can be coupled to the body 10.

[0026] The body 10 can house a power supply 11 and a control unit 12. The power supply 11 can supply the power necessary for the configuration to operate. The power supply 11 can be called a battery 11. The control unit 12 can control the operation of the configuration.

[0027] The first container 20 may have a first chamber C1 inside. The first container 20 may be equipped with a core 25. The core 25 may be placed in the first chamber C1. The upper end of the core 25 may protrude from the first chamber C1 to the upper side of the first container 20.

[0028] The first container 20 may be equipped with a heater 2531. The heater 2531 may be located in the first chamber C1. The heater 2531 can heat the wick 25. The heater 2531 may be attached to the wick 25. The first container 20 may be equipped with a terminal 223 inside. The terminal 223 may be exposed on the underside of the first container 20. The terminal 223 may be electrically connected to the heater 2531. The first container 20 may be called the lower container 20 or heating module 20.

[0029] The first container 20 may be equipped with a first airflow inlet 241 formed by opening the first chamber C1. The first container 20 may be equipped with a first airflow outlet 242 formed by opening the first chamber C1.

[0030] The second container 30 can have a second chamber C2 inside. The second container 30 can store liquid in the second chamber C2. The second container 20 can be equipped with an airflow discharge channel 340. Both ends 341, 342 of the airflow discharge channel 340 can be open. The airflow discharge channel 340 can be partitioned from the second chamber C2. The second container 30 can be called the upper container 30 or the liquid storage section 30.

[0031] The mouthpiece 35 can be coupled to the upper side of the second container 30. The mouthpiece 35 can cover the top of the second container 30. The mouthpiece 35 may have a second airflow outlet 354 inside. The second airflow outlet 354 can communicate with the other end 342 of the airflow outlet 340.

[0032] The first container 20 can be coupled to the body 10. The first container 20 can be inserted inside the body 10. When the first container 20 is coupled to the body, the heater 2531 can be electrically connected to the power supply 11 via terminal 223. The heater 2531 can receive power from the power supply 11 and generate heat. The heater 2531 may be a resistive heater.

[0033] The second container 30 can be coupled to the upper side of the first container 20. The coupling of the second container 30 to the first container 20 can include the second container 30 being directly coupled to the first container 20, or the second container 30 being coupled to the body 10 and indirectly coupled to the first container 20.

[0034] When the second container 30 is coupled to the first container 20, the second container 30 can supply the stored liquid to the wick 25. The wick 25 can receive and absorb the liquid from the second container 30. The heater 2531 can heat the wick that has absorbed the liquid to generate an aerosol in the first chamber C1.

[0035] Body 10 can be opened on one side to form a second airflow inlet 141. When the first container 20 is coupled to body 10, the first airflow inlet 241 can communicate with the second airflow inlet 141. When the second container 30 is coupled to the first container 20, one end 341 of the airflow discharge channel 340 and the first airflow outlet 242 can communicate. Thus, a flow path for air can be formed. The user can inhale air by placing the mouthpiece 35 in their mouth. When the user inhales air, the outside air can be supplied to the user by sequentially passing through the second airflow inlet 141, the first airflow inlet 241, the first chamber C1, the first airflow outlet 242, the airflow discharge channel 340, and the second airflow outlet 354. The air can flow together with the aerosol generated in the first chamber C1.

[0036] Therefore, the first container 20 and the second container 30 can be replaced independently of each other. For example, the consumption cycle of the liquid stored in the second container 30 and the appropriate replacement cycle of the first container 20 may differ, and the user can replace only the second container 30 separately, or only the first container 20 separately. For example, the consumption cycle of the liquid stored in the second container 30 may be shorter than the appropriate replacement cycle of the first container 20, and when the second container 30 is replaced several times, the first container 20 may only be replaced once. Therefore, the first container 20 can be used for a longer period, and cartridge replacement costs can be reduced.

[0037] Referring to Figure 2, the first container 20 can be detachably coupled to the body 10. The first coupler 151 can detachably couple the first container 20 and the body 10. For example, the first coupler 151 may include a hook groove 225 and a hook 125 that is detachably fastened to the hook groove 225. The hook 125 may be made of a material such as rubber or silicone and may also seal the space between the body and the first container 20 around the second airflow inlet 141. In another example, the first coupler 151 can couple the first container 20 and the body 10 by magnetic force.

[0038] The second container 30 can be detachably coupled to the first container 20. The second container 30 can be coupled to the upper side of the first container 20. The second container 30 can be coupled to the body 10 and indirectly coupled to the first container 20. The second coupler 152 can detachably couple the second container 30 and the body 10. For example, the second coupler 152 may include a hook groove 325 and a hook 135 that is detachably fastened to the hook groove 325. As another example, the second coupler 152 can couple the second container 30 and the body 10 by magnetic force.

[0039] Referring to Figures 3 to 5, the first container 20 may include a case 21, a wick 25, and a heater 2531. The case 21 may include a first case 22 and a second case 23.

[0040] The second case 23 can be coupled to the upper side of the first case 22. The first case 22 may have an opening on the upper side and a space 224 that forms the first chamber C1. The second case 23 may have an opening on the lower side and a space 234 that forms the first chamber C1. The first case 22 and the second case 23 can be coupled vertically to form the first chamber C1 inside.

[0041] Terminals 223 are fixed to the bottom of the first case 22 and can be exposed on the underside of the first case 22. Terminals 223 can project upward from the first case 22 toward the first chamber C1. Terminals 223 can consist of a pair that are horizontally spaced apart from each other.

[0042] The first airflow inlet 241 may be formed at the bottom of the first case 22. The first airflow inlet 241 may be formed as a plurality of perforated holes. The first airflow inlet 241 may be spaced horizontally away from the terminal 223. The first airflow inlet 241 may be formed by openings in the side walls of the first case 22 and / or the side walls of the second case 23.

[0043] Case 21 may comprise one configuration of the first coupler 151 (see Figures 1 and 2). For example, the hook groove 225 may be formed by a recess in the lower periphery of the first case 22. In another example, the hook 125 may be formed by a protrusion in the lower periphery of the first case 22. In yet another example, the first case 21 may comprise a magnet or a ferromagnetic material.

[0044] The first airflow outlet 242 may be formed on the upper wall of the second case 23. As another example, the first airflow outlet 242 may be formed on the side wall of the second case 23. The first airflow outlet 242 may be formed in a position opposite the first airflow inlet 241.

[0045] A liquid inlet 235 may be formed on the upper wall of the second case 23. The liquid inlet 235 may be formed on the upper side of the first chamber C1. The liquid inlet 235 may be separated from the second airflow outlet 242. The liquid inlet 235 may be formed on one side of the upper wall of the second case 23, and the second airflow outlet 242 may be formed on the other side of the upper wall of the second case 23. The liquid inlet 235 may be formed on the side corresponding to the terminal 223 and the supporter 227, and the first airflow outlet 242 may be formed on the side corresponding to the first airflow inlet 241.

[0046] The core 25 may include a first core part 251 and a second core part 252. The first core part 251 may be located in a first chamber C1 between a first case 22 and a second case 23. The lower edge of the first core part 252 may be supported by a supporter 227.

[0047] The second core part 252 can protrude upward from the first core part 251. The second core part 252 can be exposed to the outside of the first chamber C1 through the liquid inlet 235. The second core part 252 can protrude upward through the liquid inlet 235 and the first core sealing part 265.

[0048] The heater 2531 can be coupled to the first core part 251. The heater 2531 can heat the first core part 251. The first terminals 2533 formed at both ends of the heater 2531 can contact the second terminals 223, thereby electrically connecting the heater 2531 and the second terminals 233.

[0049] The supporter 227 can protrude upward from the bottom of the first case 22. The supporter 227 may be formed around the terminal 223. Multiple supporters 227 may be provided and arranged around the terminal 223. The supporter 227 may include a first supporter 227a and a second supporter 227b. The first supporter 227a and the second supporter 227b may be positioned in a region corresponding to the lower corner of the first core part 251.

[0050] The first supporter 227a and the second supporter 227b can be separated from each other. The second supporter 227b may be formed adjacent to the first airflow inlet 242. The second supporter 227b may be formed between the terminal 223 and the first airflow inlet 241. The second supporters 227b may be formed as a pair. The pair of second supporters 227b can be separated from each other to form a first gap 227c between them. The first supporter 227a and the second supporter 227b can be separated from each other to form a second gap 227d between them.

[0051] The sealer 26 can be attached to the upper side of the first container 20. The sealing plate 261 of the sealer 26 can cover the upper surface of the case 21. The sealer 26 can be made of an elastic material. For example, the sealer 26 can be made of rubber or silicone material.

[0052] The sealer 26 may include a first core sealing portion 265. The first core sealing portion 265 may be formed by opening the sealing plate 261 at a position corresponding to the liquid inlet 235. The first core sealing portion 265 may form one inner circumferential surface of the sealing plate 261. The first core sealing portion 265 may have a shape corresponding to the circumferential surface 235a surrounding the liquid inlet 235. The first core sealing portion 265 may protrude downward from the sealing plate 261 and be in close contact with the inside of the circumferential surface 235a of the liquid inlet 235. The second core part 252 may pass through the first core sealing portion 265 and protrude above the liquid inlet 235.

[0053] The sealer 26 may include a second core sealing portion 262. The second core sealing portion 262 may project downward from the lower surface of the sealing plate 261. The second core sealing portion 262 may be formed below the first core sealing portion 265 or below its periphery. The second core sealing portion 262 may extend along the periphery of the first core sealing portion 265.

[0054] The sealer 26 may include sealing walls 266, 267 that project upward from the upper surface of the sealing plate 261. The sealing walls 266, 267 can surround the liquid inlet 235 and the periphery of the first core sealing section 265. The sealing walls 266, 267 can extend along the periphery of the first core sealing section 265 to form a perimeter. Multiple sealing walls 266, 267 may be formed. For example, the sealing walls 266, 267 may include a first sealing wall 266 adjacent to the periphery of the first core sealing section 265 and a second sealing wall 267 spaced outward from the first sealing wall 266. The second sealing wall 267 may project upward higher than the first sealing wall 266. The second sealing wall 267 may surround the first sealing wall 266.

[0055] The sealer 26 may include an airflow sealing section 268. The airflow sealing section 268 may surround the first airflow outlet 242. The airflow sealing section 268 may protrude upward from the upper surface of the sealing plate 261. The second sealing wall 267 may protrude higher than the airflow sealing section 268. The airflow sealing section 268 may be formed on the outside of the sealing walls 266, 267.

[0056] Referring to Figures 6 and 7, the core 25 can be formed from a porous rigid body that absorbs liquid. For example, the core 25 can be formed from a porous ceramic. The core 25 can have higher rigidity and heat resistance than a cotton core.

[0057] Therefore, the core 25 is not easily deformable and can be embodied in a variety of shapes. In addition, the durability of the core 25 can be improved, and the replacement cycle of the first container 20 equipped with the core 25 can be extended.

[0058] The first core part 251 can extend horizontally to one side. The first core part 251 can have a hexahedral shape. The upper surface 2511 of the first core part 2511 can be formed horizontally. The lower surface 2513 of the first core part 2511 can be formed horizontally. The side surface 2512 of the first core part 2511 can be formed between the periphery of the upper surface 2511 and the periphery of the lower surface 2513 and can define the periphery of the first core part 251. The side surface 2512 of the first core part 251 can be called the circumferential surface 2512 of the first core part 251.

[0059] The second core part 252 can project upward from the center of the upper surface 2511 of the first core part 251. The second core part 252 can extend horizontally. The second core part 252 can have a hexahedral shape. The upper surface 2521 of the second core part 252 can be formed horizontally. The lower surface 2523 of the second core part 252 can be formed horizontally. The lower surface 2523 of the second core part 252 can overlap with the upper surface 2511 of the first core part 251. The side surface 2522 of the second core part 252 can be formed between the periphery of the upper surface 2521 and the periphery of the lower surface 2523, defining the periphery of the second core part 252. The side surface 2522 of the second core part 252 can be called the circumferential surface 2522 of the second core part 252.

[0060] The first core part 251 may be larger than the second core part 252. The circumference of the top surface 2511 of the first core part 251 may be larger than the circumference of the top surface 2522 of the second core part 252. The height H1 of the first core part 251 may be larger than the height H2 of the second core part 252. The length L1 of the first core part 251 may be larger than the length L2 of the second core part 252. The width W1 of the first core part 251 may be larger than the width W2 of the second core part 252.

[0061] The first core part 251 can protrude horizontally outward from the lower surface of the second core part 252 by predetermined widths w31, w32, w33, and w34. The second core part 252 can protrude from the inside of the periphery of the upper surface 2511 of the first core part 2511. The periphery of the upper surface 2511 of the first core part 2511 can protrude outward from the lower surface of the second core part 252.

[0062] The heater 2531 can be attached to the first core part 2531. The heater 2531 can form a pattern on the lower surface 2513 of the first core part 251. The heater 2531 can form various patterns along the length of the first core part 251. Both ends of the heater 2531 can be adjacent to both ends of the first core part 251.

[0063] A pair of first terminals 2533 may be formed at both ends of the heater 2531. The first terminals 2533 can be coupled to the underside of the first core part 251. A pair of first terminals 2533 can be adjacent to both ends of the first core part 251. The first terminals 2533 can protrude from the underside of the first core part 251.

[0064] Referring to Figures 8 and 9, the first airflow inlet 241 may be formed on the lower side of the first chamber C1. The first airflow outlet 242 may be formed on the upper side of the first chamber C1. The first airflow inlet 241 and the first airflow outlet 242 may be formed side by side. The core 25 is located on the right side of the first chamber C1, and the first airflow inlet 241 and the first airflow outlet 242 may be formed on the left side of the first chamber C1. The first channel CN1 is formed on the left side of the first chamber C1 and may include the first airflow inlet 241 and the first airflow outlet 242. Air can flow into the first channel CN1 through the first airflow inlet 241 and be discharged through the first airflow outlet 242.

[0065] The first terminal 2533 contacts the second terminal 223, thereby electrically connecting the heater 2531 and the second terminal 223. The second terminal 223 can support the first terminal 2533 and the lower surface 2513 of the first core part 251.

[0066] The lower part of the first core part 2511 can be supported by the supporter 227. The upper surface 2511 of the first core part 2511 can be supported by the lower part of the second case 23 and / or the second core sealing part 262 around the liquid inlet 235. The periphery of the side portion 2522 of the second core part 252 can be supported by the circumferential surface 235a of the liquid inlet 235 and / or the inner surface of the first core sealing part 265.

[0067] Therefore, the core 25 can be fixed to the first container 20.

[0068] The supporter 227 can separate the first core part 2511 upward from the bottom of the first chamber C1. The supporter 227 may be positioned around the heater 2513. The supporter 227 can form gaps 227c, 227d that connect the heater 2531, which is attached to the lower surface 2513 of the first core part 2511, to the first chamber C1. The supporter 227 can open between the first channel CN1 and the heater 2531 to form the first gap 227c.

[0069] The supporter 227 may include a first supporter 227a and a second supporter 227b. The second supporter 227b may be positioned closer to the first airflow inlet 241 and the first airflow outlet 242 than the first supporter 227a. The first airflow inlet 241 and the first airflow outlet 242 may be adjacent to the left side of the first core part 251. The first supporter 227a may extend along the right edge between the lower surface 2513 and the side surface 2512 of the first core part 251. The first supporter 227a may support the right corner between the lower surface 2513 and the side surface 2512 of the first core part 251. A pair of second supporters 227b may support the left corner of the first core part 251.

[0070] A pair of second supporters 227b can be separated from each other to form a first gap 227c through which air can flow between the periphery of the heater 2531 and the first airflow inlet 242. The first supporter 227a and the second supporter 227b can be separated from each other to form a second gap 227d through which air can flow between the periphery of the heater 2531 and the first airflow inlet 242. The first gap 227c and the second gap 227d can be formed around the lower surface 2513 of the first core part 251.

[0071] Therefore, the aerosol generated in the core 25 and the surrounding air can flow smoothly towards the first airflow outlet 242 by passing around the multiple supporters 227.

[0072] The first core sealing portion 265 may be positioned between the circumferential surface 2522 of the second core part 252 and the circumferential surface 235a of the liquid inlet 235. The inner circumferential surface of the first core sealing portion 265 can be in close contact with the circumferential surface 2522 of the second core part 252. The first core sealing portion 265 can seal the space between the circumferential surface 2522 of the second core part 252 and the circumferential surface 235a of the liquid inlet 235.

[0073] The perimeter of the upper surface 2511 of the first core part 251 may be larger than the perimeter of the liquid inlet 235. The perimeter of the upper surface 2511 of the first core part 251 may be formed horizontally outward than the perimeter of the liquid inlet 235. The edge portion of the first core part 251 can absorb liquid leaking between the liquid inlet 235 and the circumferential surface 2522 of the second core part 252.

[0074] The second core sealing portion 262 can protrude downward from the vicinity of the liquid inlet 235 toward the upper surface 2511 of the first core part 251. The second core sealing portion 262 can be in close contact with the upper surface 2511 of the first core part 251. The second core sealing portion 262 can support the upper surface 2511 of the first core part 251.

[0075] Therefore, the liquid supplied from the second container 30 to the core 25 is not absorbed by the core 25 and is prevented from leaking into the first chamber C1 through the space between the second core part 252 and the circumferential surface 235a of the liquid inlet 235.

[0076] Referring to Figures 10 to 12, the second container 30 can provide a second chamber C2 for storing liquid. The second chamber C2 can be defined by the lower wall 311, side walls 321, 322 and upper wall 33 of the second container 30. The side walls 321, 322 can extend vertically. The side walls 321, 322 may include an outer wall 321 forming the exterior of the second container 30 and an inner wall 322 formed inside the second container 30. The inner wall 322 is formed between the second chamber C2 and the airflow discharge channel 340 to partition the second chamber C2 and the airflow discharge channel 340 from each other.

[0077] The liquid outlet 314 may be formed by opening the second chamber C2. The liquid outlet 314 may be formed at the bottom of the second chamber C2. The liquid outlet 314 may consist of multiple holes. The liquid stored in the second chamber C2 can be discharged through the liquid outlet 314.

[0078] The discharge guide 313 may be formed around the liquid outlet 314. The discharge guide 313 may be formed to slope downward toward the liquid outlet 314. The discharge guide 313 may be formed on the lower surface 311 of the second chamber C2. The discharge guide 313 can guide the liquid stored in the second chamber C2 to the liquid outlet 314.

[0079] The absorbent portion 316 can block the lower part of the liquid outlet 314. The absorbent portion 316 can absorb the liquid that has passed through the liquid outlet 314. For example, the absorbent portion 316 may be made of felt material.

[0080] The bracket 317 can protrude downward from the second container 30 around the liquid outlet 314. The bracket 317 can surround the side perimeter of the absorbent section 316. The absorbent section 316 can be exposed from the bracket 317 to the underside of the second container 30. The bracket 317 can fix the absorbent section 316 to the lower part of the first container 30. The bracket 317 can support the lower perimeter of the absorbent section 316 in a hook shape.

[0081] The film 316a can be detachably attached to the lower surface of the absorbent section 316. The edges of the film 316a can be attached to the lower surface of the bracket 317. The film 316a may be made of a waterproof material. The film 316a can prevent liquid from leaking from the absorbent section 316. Prior to joining the second container 30 to the first container 20, the user can remove the film 316a from the absorbent section 316.

[0082] The recess 315 can be formed by the lower surface 312 of the second container 30 being recessed upward. The groove formed by the recess 315 can surround the bracket 317.

[0083] The second container 30 may have one configuration of the second coupler 152 (see Figures 1 and 2). For example, the hook groove 325 may be formed by a recess in the outer wall 321 of the second container 30. In another example, the hook 135 may be formed by a protrusion of the outer wall 321 of the second container 30. In yet another example, the second container 30 may be equipped with a magnet or a ferromagnetic material.

[0084] The second container 30 may have an airflow discharge channel 340. The airflow discharge channel 340 may be separated from the second chamber C2 by the inner wall 322 of the second container 30. The airflow discharge channel 340 may be defined by the outer wall 321 and the inner wall 322 of the second container 30. Both ends of the airflow discharge channel 340 may be open. One end of the airflow discharge channel 340 may open downwards. The other end of the airflow discharge channel 340 may open upwards. One end of the airflow discharge channel 340 may be formed by an opening in the lower surface 312 of the second container 30. The other end of the airflow discharge channel 340 may communicate with a second airflow outlet 354 formed inside the mouthpiece 35. The airflow discharge channel 340 may be called the second channel CN2.

[0085] Referring to Figures 13 and 14, the first container 20 can be detachably coupled to the body 10. The first coupler 151 can detachably couple the first container 20 and the body 10. The second container 30 can be detachably coupled to the first container 20. The second container 30 can be indirectly coupled to the first container 20 by coupling to the body 10 via the second coupler 152. The second container 30 can be coupled to the upper side of the first container 20.

[0086] When the second container 30 is coupled with the first container 20, the second container 30 can supply liquid to the wick 25. The liquid stored in the second chamber C2 passes through the liquid outlet 314 and is absorbed into the absorbent section 316. The absorbent section 316, having absorbed the liquid, can then come into contact with the second wick part 252 and transfer the liquid. The liquid absorbed into the second wick part 252 can then diffuse to the first wick part 251. The heater 3531 can heat the first wick part 251, which has absorbed the liquid, to generate an aerosol.

[0087] The sealer 26 can seal around the liquid inlet 235 where the core 25 is exposed from the first chamber C1. When the second container 30 is joined to the top of the first container 20, the sealer 26 can seal between the first container 20 and the second container 30.

[0088] The sealing walls 266 and 267 can project toward the second container 30. The sealing walls 266 and 267 can be in close contact with the second container 30. The sealing walls 266 and 267 can surround the liquid inlet 235.

[0089] Therefore, it is possible to prevent the liquid discharged from the second container 30 from leaking into the gap between the first container 20 and the second container 30.

[0090] Referring to Figure 15, the first sealing wall 266 can surround the liquid inlet 235 and the periphery 2522 of the second core part 252. The first sealing wall 266 can be in close contact with the bottom of the second container 30. The first sealing wall 266 can be in close contact with the protruding portion formed inside the recess 266. For example, the first sealing wall 266 can be in close contact with the bracket 317. The bracket 317 and the first sealing wall 266 can surround the periphery 2522 of the second core part 252. Thus, the bracket 317 can not only fix the absorbent part 316 but also press the first sealing wall 266 to seal the periphery of the second core part 252 and the liquid inlet 235.

[0091] The second sealing wall 267 can protrude higher than the first sealing wall 266. The second sealing wall 267 can be positioned horizontally outside the first sealing wall 266 and surround the first sealing wall 266. The second sealing wall 267 can be in close contact with the bottom of the second container 30. The second sealing wall 267 can be inserted into the groove formed by the recess 315 and be in close contact with the recess 315.

[0092] Therefore, the first sealing wall 266 can seal around the second core part 252 and the liquid inlet 235. Furthermore, even if the liquid flows beyond the first sealing wall 266, it can be sealed by the second sealing wall 267.

[0093] Referring to Figures 15 and 16, the first channel CN1 may be formed on the left side of the first chamber C1. The core 25 and heater 2531 may be located on the right side of the first chamber C1. The first channel CN1 may include a first airflow inlet 241 and a first airflow outlet 242. The first airflow inlet 241 may be formed at one end of the first channel CN1. The first airflow outlet 242 may be formed at the other end of the first channel CN1. The first channel CN1 may be offset from the core 25 with respect to the vertical. The core 25 may be spaced apart from the first airflow inlet 241 and the second airflow inlet 242. Unlike the illustrations, at least one of the first airflow inlet 241 and the first airflow outlet 242 may be formed by an opening in the side wall of the first container 20 in the first channel CN1.

[0094] When the first container 20 is coupled to the body 10, the second airflow inlet 141, which is formed by an opening on one side of the body 10, can communicate with the first airflow inlet 241. The gap between the body 10 and the first container 20 can be sealed around the second airflow inlet 141. For example, a hook 125 can seal the gap between the body 10 and the first container 20 around the second airflow inlet 141.

[0095] When the second container 30 is coupled to the first container 20, the first airflow outlet 242 and the lower end of the second channel CN2 can communicate. The first channel CN1 and the second channel CN2 can communicate to form a single flow path CN. The second channel CN2 can communicate with the second airflow outlet 354.

[0096] When a user places the mouthpiece 35 in their mouth and inhales air, external air can be supplied to the user by sequentially passing through the second airflow inlet 141, the first channel CN1, the second channel CN2, and the second airflow outlet 354. Aerosols can be generated in the first chamber C1, which is separated from the first channel CN1. Due to the inhalation force and pressure difference, the air passing through the first channel CN1 can flow together with the air and aerosols in the first chamber C1. The air and aerosols can flow into the first channel CN1 by passing through the first gap 227c and the second gap 227d between the supporters 227.

[0097] Therefore, by ensuring that air flows only to one side of the first chamber C1, the size of the flow path can be reduced, and the size of the aerosol generator can be reduced or optimized. In addition, the airflow resistance can be reduced from the structure supporting the core 25.

[0098] The airflow sealing section 268 can be in close contact with the lower part of the second container 30 around the lower end of the second channel CN2. The airflow sealing section 268 can surround the lower end of the second channel CN2 and the first airflow outlet 242. The airflow sealing section 268 can seal the space between the first container 20 and the second container 30 around the lower end of the airflow discharge channel 340 and the first airflow outlet 242.

[0099] Therefore, it is possible to prevent air passing through the airflow discharge channel 340 from the first airflow outlet 242 from leaking between the first container 20 and the second container 30, thereby improving the airflow efficiency.

[0100] Referring to Figure 17, the first airflow inlet 241' and the second airflow inlet 141' may be formed in different locations than in the embodiment of Figure 16. The first airflow inlet 241' may be formed on the side of the first chamber C1. The second airflow inlet 141' may be formed in the body 10 and may communicate with the first airflow inlet 241'. The second airflow inlet 141' may face the first airflow inlet 241'.

[0101] The first channel CN1' is formed in the first chamber C1 and may have a first airflow inlet 241' and a first airflow outlet 242 at both ends. The core 25 may be positioned between the first airflow inlet 241' and the first airflow outlet 242. The first channel CN1' can pass through the core 25. The first channel CN1' can communicate with the second channel CN2 to form a flow path CN' through which air flows.

[0102] The four second supporters 227b can support the four lower vertices of the first core part 251. The first gap 227c can be formed around the lower periphery of the first core part 251. The first channel CN1' can pass through the first gap 227c.

[0103] Air can be discharged by sequentially flowing through the second airflow inlet 141', the first channel CN1', the second channel CN2, and the second airflow outlet. The air may be accompanied by aerosols from the first chamber C1 as it passes through the first channel CN1'.

[0104] Therefore, the size of the flow path can be reduced, and the size of the aerosol generator can be reduced. In addition, the airflow resistance from the structure supporting the core 25 can be reduced.
