[0030] A singular expression includes plural expressions unless explicitly indicated otherwise in the context.

[0031] Referring to Figures 1 and 2, the aerosol generator may include at least one of a battery 101, a control unit 102, and a sensor 103. At least one of the battery 101, the control unit 102, and the sensor 103 may be located inside the body 10 of the aerosol generator. The body 10 may provide an upwardly opening space into which a stick S is inserted. The lower end of the stick S is inserted inside the body 10, and the upper end of the stick S may protrude outside the body 10. The user can inhale air by placing the exposed upper end of the stick S in their mouth.

[0032] The heater 50 can heat the stick S. The heater 50 can extend upwards in the space into which the stick S is inserted. The heater 50 can be inserted at the bottom of the stick S. The heater 50 may be a resistive heater.

[0033] The battery 101 can supply power to enable the components of the aerosol generator to operate. The battery 101 can supply power to at least one of the control unit 102, sensor 103, induction coil 15, and heater rod 30. The battery 101 can supply the power necessary for the display, motor, and other components installed in the aerosol generator to operate.

[0034] The control unit 102 can control the overall operation of the aerosol generator. The control unit 102 can control the operation of at least one of the following: the battery 101, the induction coil 15, and the sensor 103. The control unit 102 can control the operation of displays, motors, and other components installed in the aerosol generator. The control unit 102 can check the status of each component of the aerosol generator and determine whether the aerosol generator is operational.

[0035] Sensor 103 can sense the temperature of heater 50. Control unit 102 can control the temperature of heater 50 based on the temperature of heater 50 sensed by sensor 103. Control unit 102 can transmit information about the temperature of heater 50 sensed by sensor 103 to the user via the user interface.

[0036] The aerosol generator may include an induction coil 15 surrounding a heater 50. The induction coil 15 can cause the heater 50 to generate heat. The heater 50 is a susceptor, and it can generate heat through a magnetic field generated by an AC current flowing through the induction coil 15. The magnetic field penetrates the heater 50 and can generate eddy currents within it. The current can generate heat in the heater 50. Unlike the illustrated configuration, the heater 50 can be electrically connected to a battery 101. The heater 50 can also generate heat directly by receiving current from the battery 101 without the need for the induction coil 15.

[0037] Referring to Figures 2 to 4, the body 10 may have a shape that extends vertically. The body 10 may have a first insertion space 14 inside. The first insertion space 14 may open upwards. The first insertion space 14 may have a cylindrical shape that extends vertically. The first insertion space 14 may be defined by a body pipe 11 formed inside the body 10. The body pipe 11 may include a lateral wall 111 surrounding the first insertion space 14 and a bottom wall 112 covering the bottom of the first insertion space 14. The bottom wall 112 may be formed at the bottom of the body pipe 11. The lateral wall 111 of the body pipe 11 can be called the inner lateral wall 111 of the body 10.

[0038] The heater holder 20 can be detachably inserted into the first insertion space 14. The heater holder 20 can provide a second insertion space 24 inside. The second insertion space 24 can open upwards. The second insertion space 24 may have a cylindrical shape. The second insertion space 24 can be defined by a pipe 20' of the heater holder 20. The pipe 20' may include side walls 21 surrounding the second insertion space 24 and a bottom wall 22 covering the bottom of the second insertion space 24. The bottom wall 22 of the pipe 20' can be called a bottom 22 or mount 22. The bottom wall 22 of the pipe 20' can form the bottom 22 of the heater holder 20. The heater 50 can be coupled to or fixed to the heater holder 20. The pipe 20' can be called a heater holder pipe 20'.

[0039] The extractor 30 can be detachably inserted into the second insertion space 24. The extractor 30 can provide a third insertion space 34 inside. The third insertion space 34 can open on one side. The third insertion space 34 may have a cylindrical shape. The third insertion space 34 can be defined by the side wall 31 and the bottom wall 32 of the extractor 30. The outer circumferential surface of the extractor 30 may have a cylindrical shape.

[0040] The lower end of the stick S is inserted into the third insertion space 34, and the upper end of the stick S can protrude outside the aerosol generator. The heater 50 can heat the first insertion space 14, the second insertion space 24, and the third insertion space 34. The heater 50 can heat the stick S inserted into the third insertion space 34.

[0041] Therefore, the heater 50 can be easily replaced. The size of the heaters 50 placed in the insertion spaces 14, 24, and 34 may be too small to be easily replaced, but the user can easily replace the heater 50 by separating the heater holder 20 from the aerosol generator and placing a new heater holder 20 in the aerosol generator.

[0042] Furthermore, foreign matter generated from the stick S does not remain around the heater 50 or in the heater holder 20, but can be extracted via the extractor 30. Therefore, cleaning of the aerosol generating device around the heater 50 can be easily performed, improving ease of management. In addition, factors that degrade the performance of the heater 50 are reduced, improving the durability of the heater 50 and extending the replacement cycle of the heater 50. Furthermore, factors that alter the taste of the stick S are reduced.

[0043] The lower end of the heater 50 can be fixed to the mount 22. The heater 50 can extend elongated toward the opening of the second insertion space 24. The heater 50 can be formed in a cylindrical shape with its upper end pointed upwards. As another example, the heater 50 can have a circumferential shape and be coupled to the side wall 21 of the heater holder 20. However, this is merely illustrative, and the shape of the heater 50 is not limited to those described or illustrated above, as long as it can be coupled to the heater holder 20 and heat the stick S inserted into the third insertion space 34.

[0044] The heater holder 20 can be formed by insert injection molding onto the heater 50. The heater holder 20 can have high heat resistance and excellent rigidity. For example, the heater holder 20 can be formed from polyetheretherketone (PEEK). However, the material of the heater holder 20 is not limited to this.

[0045] The through-hole 35 can be formed by an opening in the lower wall 32 of the extractor 30. The through-hole 35 can open vertically. When the extractor 30 is inserted into the second insertion space 24, the heater 50 can protrude through the through-hole 35 into the third insertion space 34. When the stick S is inserted into the third insertion space 34, the heater 50 can be inserted below the stick S.

[0046] The induction coil 15 can surround the first insertion space 14. The induction coil 15 can be wound around the side wall 111 of the body pipe 11. The induction coil 15 can surround the heater 50. The induction coil 15 can cause the heater 50 to generate heat. As another example, the heater 50 can also be directly electrically connected to a power source via terminals formed on the heater holder 20 and generate heat by receiving power.

[0047] Therefore, the stick S can be easily separated from the heater 50. The user can easily separate the stick S from the heater 50 by separating the extractor 30 and the heater holder 20 from each other. The stick S, which is inserted inside the extractor 30, can be more easily separated from the extractor 30 by separating it from the heater 50. The stick S can also be separated even when the extractor 30 and the heater holder 20 are not separated from each other.

[0048] Furthermore, foreign matter generated from the stick S does not remain around the heater 50 or in the heater holder 20, but can be extracted via the extractor 30. Therefore, cleaning of the aerosol generating device around the heater 50 is made easier, improving ease of management. In addition, factors that reduce the performance of the heater 50 are reduced, improving the durability of the heater 50 and extending the replacement cycle of the heater 50. Furthermore, factors that alter the taste of the stick S are reduced.

[0049] The heater holder 20 may be positioned between the body 10 and the extractor 30. The side wall 111 of the body pipe 11 may surround the side wall 21 of the heater holder 20. The bottom wall 112 of the body pipe 11 may face the bottom wall 22 of the heater holder 20. The side wall 21 of the heater holder 20 may surround the side wall 31 of the extractor 30. The bottom wall 22 of the heater holder 20 may face the bottom wall 32 of the extractor 30.

[0050] The side wall 31 of the extractor 30 can be separated inward from the side wall 21 of the heater holder 20. The bottom wall 32 of the extractor 30 can be separated upward from the bottom wall 22 of the heater holder 20. Air can flow between the extractor 30 and the heater holder 20, pass through the through hole 35, and then be supplied to the stick S inserted into the third insertion space 34.

[0051] The upper wall 12 of the body 10 can extend outward horizontally from the upper end of the body pipe 11. The upper wall 12 of the body 10 can cover the upper end of the induction coil 15. The outer lateral wall 13 of the body 10 can extend downward from the outer end of the upper wall 12 of the body 10. The outer lateral wall 13 of the body 10 can face the side wall 111 of the body pipe 11. The outer lateral wall 13 of the body 10 can be spaced outward from the body pipe 11. The induction coil 15 can be positioned between the body pipe 11 and the outer lateral wall 13 of the body 10.

[0052] The upper case 40 can be detachably coupled to the body 10. The upper case 40 can be coupled to the upper side of the body 10. The upper case 40 can cover the periphery of the first insertion space 14 and the periphery of the upper part of the body 10. The upper case 40 may be provided with an insertion opening 44. The stick S can be inserted into the insertion opening 44. The upper case 40 may include a cap 45 for opening and closing the insertion opening 44. The cap 45 can slide laterally to open and close the insertion opening 44. The heater holder 20 may be positioned between the body 10 and the upper case 40.

[0053] The upper case 40 may include an upper case body 41. An insertion opening 44 may be formed by the upper case body 41 opening vertically. The insertion opening 44 may be formed off-center from the center of the upper case body 41. The lower surface of the upper case body 41 may have a shape corresponding to the upper wall 12 of the body 10. The lower surface of the upper case body 41 may extend horizontally parallel to the upper wall 12 of the body 10. The cap 45 may be installed so as to be able to slide on the upper side of the upper case body 41.

[0054] The upper case 40 may include upper case wings 42. The upper case wings 42 may extend downward from both sides of the upper case body 41. Part of the side of the upper case body 41 may be exposed between the pair of upper case wings 42 (see Figure 7). The upper case wings 42 can be called upper case grips 42.

[0055] The extractor 30 can be coupled to the upper case 40. The upper end of the extractor 30 can be coupled to the upper case 40, and the lower end of the extractor 30 can protrude below the upper case 40. The extractor 30 can be coupled to a position corresponding to the insertion port 44. The insertion port 44 may be located above the third insertion space 34. The insertion port 44 can connect the third insertion space 34 to the outside of the aerosol generator.

[0056] The upper end of the extractor 30 can be coupled to the upper case body 41. The extractor 30 can extend downward from the upper case body 41. The extractor 30 can be positioned between a pair of upper case wings 42.

[0057] The body 10 may include body wings 16. The body wings 16 may extend upward from the edge of the upper wall 12 of the body 10. The body wings 16 may be formed as a pair facing each other centered on the upper part of the body 10 (see Figure 7). The body wings 16 may be formed at a position offset from the upper case wing 42.

[0058] When the upper case 40 is coupled to the body 10, the upper case 40 can form the upper exterior of the aerosol generator. When the upper case 40 is coupled to the body 10, the body wings 16 can cover the exposed sides of the upper case body 41 between the upper case wings 42. When the upper case 40 is coupled to the body 10, the upper case wings 42 can cover the outer wall 13 of the body 10.

[0059] Therefore, the user can more easily separate the extractor 30 from the body 10. The user can separate the extractor 30 from the body 10 by grasping the exterior of the upper case 40 and separating it, without the inconvenience of gripping the extractor 30 inserted into the second insertion space 24. For example, the user can easily separate the upper case 40 and the extractor 30 from the body 10 by grasping the pair of upper case wings 42 and pulling them away from the body 10.

[0060] The extractor 30 may include engaging projections 37. The engaging projections 37 can project outward horizontally from the outer circumferential surface of the upper end of the extractor 30. Multiple engaging projections 37 may be composed of several projections 37. Multiple engaging projections 26 may be arranged spaced apart from each other in the circumferential direction. The engaging projections 37 can be inserted into grooves formed in the upper case body 41 around the insertion opening 44, thereby fixing the extractor 30 to the upper case 40. The engaging projections 37 can interlock with the upper case body 41 in the circumferential direction.

[0061] Therefore, it is possible to prevent the extractor 30 from rotating circumferentially relative to the upper case 40 during the insertion and separation process of the stick S.

[0062] The heater holder 20 may include an extension 23. The extension 23 may be formed at the upper end of the heater holder 20. The extension 23 may extend outward horizontally from the upper end of the pipe 20'. The extension 23 may have a plate shape. The extension 23 may be formed with one side longer than the other around the pipe 20'. The extension 23 can be called a heater holder extension 23.

[0063] The extension 23 may have a shape corresponding to the upper wall 12 of the body 10. The extension 23 may be formed horizontally on the upper wall 12 of the body 10. When the pipe 20' is inserted into the first insertion space 14, the extension 23 can be supported or seated on the upper wall 12 of the body 10. The upper wall 12 of the body 10 can support the extension, and the extension 23 can support the pipe 20'. The pipe 20' can hang from the extension 23 and form an air gap by moving upward away from the bottom 112 of the body pipe 11. The outer circumferential surface of the pipe 20' can form an air gap by moving inward away from the side wall 111 of the body pipe 11.

[0064] The extension 23 may have a shape corresponding to the lower surface of the upper case body 41. The extension 23 may be formed horizontally on the lower surface of the upper case body 41. When the upper case 40 is coupled to the body 10 and the extractor 30 is inserted into the pipe 20', the extension 23 can contact the lower surface of the upper case body 41.

[0065] The first connecting member 27 can be fixed to the heater holder 20. For example, the first connecting member 27 can be fixed to the extension 23. The first connecting member 27 can be fixed to the inside or outside surface of the extension 23. The heater holder 20 can be insert-injected molded with the first connecting member 27 and the heater 50.

[0066] The extension 23 may include a first extension 231 and a second extension 232. The first extension 231 may extend from the pipe 20' to one side, and the second extension 232 may extend from the pipe 20' to the other side. The first extension 231 may be longer than the second extension 232. The circumference of the first extension 231 may be larger than the circumference of the second extension 232. The first extension 231 may be formed wider horizontally than the second extension 232. With respect to the pipe 20' extending downward from the plate-shaped extension 23, one side may be defined as the first extension 231 and the other side as the second extension 232. The pipe 20' may extend downward from a portion offset to one side from the center of the extension 23.

[0067] The first connecting member 27 can be fixed to a first extension 231 of the extension 23 that extends elongatedly to one side from the pipe 20'. The first connecting member 27 may have a plate shape. The first connecting member 27 can be widely arranged horizontally on the first extension 23. The position in which the first connecting member 27 is positioned is not limited thereto. For example, the first connecting member 27 can also be fixed to the pipe 20'.

[0068] The first coupling member 27 may be made of a magnetic material. The first coupling member 27 may be made of a ferromagnetic material. For example, the first coupling member 27 may be made of stainless steel. However, the material of the first coupling member 27 is not limited to these.

[0069] The second coupling member 47 can be fixed to the upper case 40. The second coupling member 47 can be fixed inside the upper case body 41. The second coupling member 47 can be positioned adjacent to the lower surface of the upper case body 41. However, the position in which the second coupling member 47 is positioned is not limited to these. For example, the second coupling member 47 can also be fixed to the upper case wing 42. As another example, the second coupling member 47 can also be fixed to the extractor 30. The second coupling member 47 can be positioned in a location corresponding to the first coupling member 27.

[0070] The second coupling member 47 can exert an attractive force on the first coupling member 27. For example, the first coupling member 27 may be a ferromagnetic material, and the second coupling member 47 may be a magnet. However, the materials of the first coupling member 27 and the second coupling member 47 are not limited to these.

[0071] The third coupling member 17 can be fixed inside the body 10. The third coupling member 17 can be positioned adjacent to the upper wall 12 of the body 10. The third coupling member 17 can be positioned in a location corresponding to the first coupling member 27. However, the position in which the third coupling member 17 is positioned is not limited to this; for example, the third coupling member 17 can also be positioned adjacent to the side wall 111 of the body pipe 11. The third coupling member 17 can exert an attractive force on the first coupling member 27. For example, the first coupling member 27 may be a ferromagnetic material and the third coupling member 17 may be a magnet. However, the materials of the first coupling member 27 and the third coupling member 17 are not limited to this.

[0072] Referring to Figure 5, the outer surface of the side wall 21 of pipe 20' can form multiple angles in the circumferential direction. The cross-section of the outer surface of the side wall 21 of pipe 20' may be polygonal. Each of the outer surfaces of the side wall 21 of pipe 20' can extend long vertically and include multiple faces arranged in an angular manner along the circumferential direction. The outer surface of pipe 20' can be separated inward from the side wall 111 of body pipe 11 to form an air gap (see Figure 3). The heater 50 can be surrounded by the extractor 30 and pipe 20'. The extractor 30 and pipe 20' can be separated to form an air gap.

[0073] Therefore, the amount of heat generated from the heater 50 that is transferred to the body pipe 11 (see Figure 3) through the pipe 20' can be reduced, thereby reducing the phenomenon of the aerosol generator overheating.

[0074] Referring to Figure 6, the guide portion 25 may be formed on the inner circumferential surface of the upper end of the pipe 20'. The guide portion 25 may be positioned between the pipe 20' and the extension portion 23. The guide portion 25 may be in contact with the opening of the second insertion space 24. The guide portion 25 may extend diagonally downward. The guide portion 25 may extend circumferentially so as to surround the opening of the second insertion space 24.

[0075] Therefore, the guide portion 25 contacts the lower part of the extractor 30, guiding the extractor 30 so that it can be easily inserted into the second insertion space 24.

[0076] The lower end of the heater 50 can be inserted into and fixed to the mount 22. The heater 50 may include a heater rod 51. The heater rod 51 may form the exterior of the heater 50. The heater rod 51 may extend long vertically. The heater rod 51 may have a cylindrical shape. The heater rod 51 may have a hollow opening on the lower side. The hollow may extend long vertically. The hollow inside the heater rod 51 may be formed in a cylindrical shape. The upper end of the heater rod 51 may be formed to be pointed upwards. The heater rod 51 may have high thermal expandability, excellent thermal insulation, and low thermal conductivity. The heater rod 51 may have high rigidity. For example, the heater rod 51 may be made of zirconia. However, the material of the heater rod 51 is not limited to this.

[0077] The heater 50 may include a heating element 52. The heating element 52 can be inserted into the hollow interior of the heater rod 51. The heating element 52 can extend vertically. The heating element 52 may be formed in a cylindrical shape. The heating element 52 may be made of a resistant metal. Heat generated from the heating element 52 can be transferred to the outside of the heater 50 via the heater rod 51. The heating element 52 may be positioned at a height corresponding to the third insertion space 34 (see Figure 3). The lower end of the heating element 52 may be adjacent to the lower end of the through hole 35.

[0078] The heater 50 may include a support 53. The support 53 can be inserted into the hollow of the heater rod 51. The support 53 may be positioned below the heating element 52. The support 53 can be hollow and fixed to the heater rod 51. The support 53 can support the lower part of the heating element 52. The lower end of the support 53 can be supported by the bottom 22a of the mount 22. A hole 22c formed in the center of the mount 22 may be formed by the process of insert injection molding the heater holder 20. The width of the hole 22c is formed to be smaller than the width of the support 53 to prevent the support 53 from detaching. The hole 22c is optional. The support 53 may have high heat resistance. The support 53 will not deform due to the heat generated by the heating element 52. The support 53 may be made of polyamide. However, the material of the support 53 is not limited to this.

[0079] The heater 50 may include a flange 55. The flange 55 may be formed at the lower end of the heater rod 51. The flange 55 may extend outward horizontally from the outer circumferential surface of the lower end of the heater rod 51. The flange 55 may extend circumferentially around the heater rod 51. The lower end of the heater rod 51 and the flange 55 can be inserted into a mount 22. The mount 22 can be integrally coupled to the flange 55 by insert injection molding of the heater holder 20 into the heater 50.

[0080] The cross-section of the outer surface of the flange 55 may have a non-circular shape. The inner surface of the mount 22 may have a shape corresponding to the outer surface of the flange 55. The inner surface of the mount 22 and the outer surface of the flange 55 can interlock with each other in the circumferential direction. Therefore, it is possible to prevent the heater 50 from rotating circumferentially relative to the heater holder 20 during the process of separating the stick S from or inserting the heater 50.

[0081] The flange 55 may include a first engaging portion 55a. The first engaging portion 55a may project outward from the periphery of the flange 55. The first engaging portion 55a may be formed on the lower part of the flange 55. The first engaging portion 55a may extend along the periphery of the flange 55.

[0082] The mount 22 may include a second engaging portion 22b. The second engaging portion 22b may project inward toward a groove in the mount 22. The second engaging portion 22b may have a shape corresponding to the first engaging portion 55a. The first engaging portion 55a may be located below the second engaging portion 22b. The first engaging portion 55a and the second engaging portion 22b may overlap vertically. By supporting the first engaging portion 55a, the second engaging portion 22a can prevent the flange 55 from detaching upward from the mount 22.

[0083] The extension 23 can extend further to one side with respect to the pipe 20' or the second insertion space 24. With respect to one horizontal direction, the length L1 of the first extension 231 may be greater than the length of the second extension 232. The length L1 of the first extension 231 may be greater than the diameter L0 of the second insertion space 24. Alternatively, the length L1 of the first extension 231 can be closer to the diameter L0 of the second insertion space 24 than the length of the second extension L2. The first connecting member 27 may have a plate shape. The first connecting member 27 can be fixed horizontally to the first extension 23.

[0084] Referring to Figures 7 to 9, the upper case 40 can be separated from the body 10. The heater holder 20 can be detachably coupled to the upper case 40. When the upper case 40 is separated from the body 10, the heater holder 20 can be separated from the body 10 together with the upper case 40 while still coupled to it. When the upper case 40, with the heater holder 20 coupled to it, is separated from the body 10, the heater holder 20 can be separated from the upper case 40.

[0085] As another example, the heater holder 20 can be detachably coupled to the extractor 30. When the extractor 30 is separated from the body 10, the heater holder 20 can be separated from the body 10 together with the extractor 30, while still coupled to the extractor 30. When the extractor 30, to which the heater holder 20 is coupled, is separated from the body 10, the heater holder 20 can be separated from the extractor 30.

[0086] The first coupling member 27 and the second coupling member 47 can exert an attractive force on each other. The first coupling member 27 and the second coupling member 47 can detachably connect the heater holder 20 to the upper case 40 and / or the extractor 30. As an example, the first coupling member 27 and the second coupling member 47 may be magnets that exert an attractive force on each other. As another example, one of the first coupling member 27 and the second coupling member 47 may be a ferromagnetic material and the other may be a magnet. However, the invention is not limited to the above, and the first coupling member 27 and the second coupling member 47 may be configured to exert an attractive force on each other by electric or magnetic force.

[0087] The extension 23 can form a horizontal surface corresponding to the lower surface of the upper case body 41. The first extension 231 can form a horizontal surface corresponding to the lower surface of the upper case body 41. The upper surface of the extension 23 can be horizontally supported by the upper case body 41. The area supported by the upper case body 41 of the first extension 231 may be larger than that of the second extension 232.

[0088] The first connecting member 27 may have a plate shape. The first connecting member 27 can be fixed horizontally to the first extension 231. The second connecting member 47 may be positioned adjacent to the lower surface of the upper case body 41. The second connecting member 47 may be formed in a position corresponding to the first connecting member 27. Due to the attractive force between the first connecting member 27 and the second connecting member 47, the first extension 231 can come into contact with the lower surface of the upper case body 41.

[0089] As another example, the heater holder 20 can be detachably connected to the upper case 40 by a screw connection. Here, the heater holder 20 can rotate circumferentially to be separated from or connected to the upper case 40 by a screw connection. Alternatively, the heater holder 20 and the upper case 40 can be detachably connected using fastening screws. As yet another example, the heater holder 20 can be detachably connected to the upper case 40 by a snap-fit ​​connection. Here, either the heater holder 20 or the upper case 40 may be provided with a connecting hook, and the other may be provided with a groove into which the hook connects. These are merely examples, and the methods by which the heater holder 20 can be detachably connected to the upper case 40 are not limited to those described above. The heater holder 20 can be detachably connected to the upper case 40 by a variety of known methods.

[0090] The heater holder 20, coupled to the upper case 40, can protrude downward from the upper case 40. The heater holder 20 can be positioned between a pair of upper case wings 42. The pipe 20' can protrude downward from the upper case body 41 beyond the upper case wings 42. Thus, the heater holder 20 is easy to grasp.

[0091] Therefore, the heater holder 20 can be easily separated from the upper case 40 while still being stably attached to the upper case 40. Furthermore, the heater 50 can be conveniently replaced.

[0092] Furthermore, the stick S can be easily separated from the heater 50. The user can easily separate the stick S from the heater 50 by separating the extractor 30 and the heater holder 20 from each other. The stick S, which is inserted inside the extractor 30, can be more easily separated from the extractor 30 once it is separated from the heater 50.

[0093] Referring to Figures 10 and 11, the heater holder 20 can be detachably coupled to the body 10. With the heater holder 20 coupled to the body 10, the upper case 40 and / or extractor 30 can be separated from the body 10 and the heater holder 20. With the upper case 40 and / or extractor 30 separated from the body 10 and the heater holder 20, the heater holder 20 can be separated from the body 10.

[0094] The first coupling member 27 and the third coupling member 17 can exert an attractive force on each other. The first coupling member 27 and the third coupling member 17 can detachably connect the heater holder 20 to the body 10. As an example, the first coupling member 27 and the third coupling member 17 may be magnets that exert an attractive force on each other. As another example, one of the first coupling member 27 and the third coupling member 17 may be a ferromagnetic material and the other may be a magnet. However, the invention is not limited to the above, and the first coupling member 27 and the third coupling member 17 may be configured to exert an attractive force on each other by electric or magnetic force.

[0095] The extension 23 covers the upper wall 12 of the body 10, and the pipe 20' can be inserted into the first insertion space 14. The extension 23 can form a horizontal surface corresponding to the upper wall 12 of the body 10. The first extension 231 can correspond to one side of the upper wall 12 of the body 10, and the second extension 232 can correspond to the other side of the upper wall 12 of the body 10. The lower surface of the extension 23 can be horizontally supported by the upper wall 12 of the body 10. The area supported by the body 10 of the first extension 231 may be larger than that of the second extension 232.

[0096] The first connecting member 27 may have a plate shape. The first connecting member 47 can be fixed horizontally to the first extension 231. The third connecting member 17 may be positioned adjacent to the upper wall 12 of the body 10. The third connecting member 17 may be formed in a position corresponding to the first connecting member 27. The first connecting member 27 is positioned on the first extension 231, and the third connecting member 17 may be positioned adjacent to the upper wall 12 on one side of the body 10 covered by the first extension 231. Due to the attractive force between the first connecting member 27 and the third connecting member 47, the first extension 231 can come into contact with the upper wall 12 of the body 10.

[0097] As another example, the heater holder 20 can be detachably connected to the body 10 by a screw connection. Here, the heater holder 20 can rotate circumferentially and be separated from or connected to the body 10 by a screw connection. Alternatively, the heater holder 20 and the body 10 can be detachably connected using fastening screws. As yet another example, the heater holder 20 can be detachably connected to the body 10 by a snap-fit ​​connection. Here, either the heater holder 20 or the body 10 may be provided with a connecting hook, and the other may be provided with a groove into which the hook connects. These are merely examples, and the methods by which the heater holder 20 can be detachably connected to the body 10 are not limited to those described above. The heater holder 20 can be detachably connected to the body 10 by a variety of known methods.

[0098] The extension 23, which is connected to the body 10, can be exposed above the body 10. The extension 23 may be positioned between a pair of body wings 16. The extension 23 may be positioned between the pair of body wings 16 adjacent to the outer wall 13 of the body 10, or parallel to the outer wall 13 vertically. Thus, it may be easy to grasp the heater holder 20.

[0099] Therefore, the heater holder 20 can be easily separated from the body 10 while still being stably attached to the body 10. In addition, the heater 50 can be conveniently replaced.

[0100] Furthermore, the stick S can be easily separated from the heater 50. The user can easily separate the stick S from the heater 50 by separating the extractor 30 and the heater holder 20 from each other. The stick S, which is inserted inside the extractor 30, can be more easily separated from the extractor 30 once it is separated from the heater 50.

[0101] The first coupling member 27 may be positioned between the second coupling member 47 and the third coupling member 17. The first coupling member 27 and the second coupling member 47 may exert an attractive force on each other, and the first coupling member 27 and the third coupling member 17 may exert an attractive force on each other. For example, the second coupling member 47 and the third coupling member 17 may each be magnets, and the first coupling member 27 may be a magnet that exerts an attractive force on the second coupling member 47 and the third coupling member 17 between the first coupling member 47 and the third coupling member 17. As another example, the first coupling member 27 may be a ferromagnetic material, and the second coupling member 47 and the third coupling member 17 may each be magnets. However, the configuration is not limited to those described above, and the first coupling member 27 may exert an attractive force on the second coupling member 47 and the third coupling member 17 by electric or magnetic force.

[0102] Therefore, the user can selectively connect the heater holder 20 to either the body 10 or the extractor 30 while the upper case 40 and / or extractor 30 are separated from the body 10. Furthermore, the upper case 40 and / or extractor 30 can be easily and stably connected to the body 10.

[0103] The attractive force between the first connecting member 27 and the second connecting member 47 and the attractive force between the first connecting member 27 and the third connecting member 17 may be different from each other. For example, the attractive force between the first connecting member 27 and the second connecting member 47 may be greater than the attractive force between the first connecting member 27 and the third connecting member 17.

[0104] Therefore, when separating the upper case 40 and / or the extractor 30 from the body 10, the heater holder 20 can be separated from the body 10 together. Furthermore, when the upper case 40 and / or the extractor 30 is attached to the body 10 with the heater holder 20 attached, the attractive force between the first connecting member 27 and the third connecting member 17 allows the upper case 40 to connect to the body 10 more easily and maintain a more stable connection.

[0105] As another example, the attractive force between the first connecting member 27 and the second connecting member 47 may be greater than the attractive force between the first connecting member 27 and the third connecting member 17. Thus, when separating the upper case 40 and / or the extractor 30 from the body, the heater holder 20 remains connected to the body 10, and the stick S can detach from the heater 50 and be separated from the extractor 30 more easily.

[0106] Referring to Figures 12 to 14, the side walls 210 of the heater holder 200 and the side walls 310 of the extractor 300 can together define a fourth insertion space 340 that opens upward. Each of the side walls 210 of the heater holder 200 and the side walls 310 of the extractor 300 can cover at least one side of the fourth insertion space 340. The side walls 210 of the heater holder 200 and the side walls 310 of the extractor 300 can together form the perimeter of the side of the fourth insertion space 340.

[0107] The side wall 210 of the heater holder 200 can extend vertically. The side wall 310 of the extractor 300 can extend vertically. Each of the side wall 210 of the heater holder 200 and the side wall 310 of the extractor 300 can be spaced equidistant from the center of the fourth insertion space 340 with respect to the radial direction. Each of the side wall 210 of the heater holder 200 and the side wall 310 of the extractor 300 can be located on the same circumferential extension of the fourth insertion space 340. Each of the side wall 210 of the heater holder 200 and the side wall 310 of the extractor 300 can extend circumferentially along the perimeter of the fourth insertion space 340.

[0108] As an example, multiple side walls 210 of the heater holder 200 may be arranged around the lower wall 22 of the heater holder 200. Between each of the multiple side walls 210 of the heater holder 200, a first slit 214 may be formed that opens upward and extends vertically. The multiple side walls 210 and the multiple first slits 214 of the heater holder 200 may be arranged alternately around each other in a circumferential direction around the fourth insertion space 340.

[0109] For example, two side walls 210 may be formed on the heater holder 200, facing each other with respect to the fourth insertion space 340. Between the two side walls 210 of the heater holder 200, two first slits 214 may be formed, also facing each other with respect to the fourth insertion space 340. However, the number of side walls 210 and first slits 214 of the heater holder 200 is not limited to this, and there may be one (see Figure 17) or three or more.

[0110] As an example, multiple side walls 310 of the extractor 300 may be arranged around the lower wall 32 of the extractor 300. Between each of the multiple side walls 310 of the extractor 300, a second slit 314 extending vertically may be formed. The multiple side walls 310 and the multiple second slits 314 of the extractor 300 may be arranged alternately around each other in a circumferential direction around the fourth insertion space 340.

[0111] For example, the extractor 300 may have two side walls 310, which may be formed facing each other around the fourth insertion space 340. Between the two side walls 310 of the extractor 300, two second slits 314 may be formed, which may also be positioned facing each other around the fourth insertion space 340. However, the number of side walls 310 and second slits 314 of the extractor 300 is not limited to this, and may be one (see Figure 17) or three or more.

[0112] The extractor 300 can be inserted inside the heater holder 200. When the extractor 300 is inserted inside the heater holder 200, the side wall 210 of the heater holder 200 may be positioned in the second slit 314, and the side wall 310 of the extractor 300 may be positioned in the first slit 214.

[0113] Therefore, the side walls 210 of the heater holder 200 and the side walls 310 of the extractor 300 can form a fourth insertion space 340. Furthermore, by reducing the thickness of the wall between the induction coil 15 and the heater 50, the heating efficiency of the heater 50 can be improved. This will be explained later in Figures 15 and 16.

[0114] The lower wall 32 of the extractor 300 can cover the lower part of the fourth insertion space 340. The lower wall 22 of the heater holder 200 is positioned below the lower wall 32 of the extractor 300 and can cover the lower part of the lower wall 32 of the extractor 300. The heater 50, which is fixed to and protrudes from the lower wall 22 of the heater holder 200, can pass through a through-hole 35 formed in the lower wall 32 of the extractor 300 and be exposed to the fourth insertion space 340.

[0115] The lower wall 22 of the heater holder 200 can be separated upward from the lower wall 112 of the body pipe 11. An air gap can be formed between the lower wall 22 of the heater holder 200 and the lower wall 112 of the body pipe 11. The lower wall 32 of the extractor 300 can be separated upward from the lower wall 22 of the heater holder 200. An air gap can be formed between the lower wall 32 of the extractor 300 and the lower wall 22 of the heater holder 200. A portion of the heat generated from the heater 50 can be transferred from the lower wall 22 of the heater holder 200 to the side wall 210, and then transferred and dispersed to the lower wall 112 and side wall 111 of the body pipe 11. In addition, a portion of the heat generated from the heater 50 can be dispersed around the heater 50 through the air gap formed between the heater holder 200 and the extractor 300.

[0116] Therefore, the amount of heat generated by the heater 50 that is conducted to the internal components of the aerosol generator can be reduced, preventing malfunctions of the aerosol generator. In addition, the amount of heat generated by the heater 50 that is conducted to the outside of the aerosol generator can be reduced, thereby reducing the phenomenon of heat being transferred to the user.

[0117] Referring to Figure 14, the side wall 210 of the heater holder 200 and the side wall 310 of the extractor 300 can interlock in the radial direction. The side wall 210 of the heater holder 200 and the side wall 310 of the extractor 300 can support each other in the radial inward and outward directions.

[0118] Therefore, the heater holder 200 and the extractor 300 can be stably positioned without shifting or swaying radially relative to each other.

[0119] For example, each of the side walls 210 of the heater holder 200 may include a first recess 211 that is recessed circumferentially from both ends 212. Both ends 212 of the side walls 210 of the heater holder 200 may protrude circumferentially beyond the first recess 211. The first recess 211 can be formed on the inner circumferential surface side of the side wall 210 of the heater holder 200, but it can also be formed on the outer circumferential surface side. The end 212 of the side wall 210 of the heater holder 200 can be called the first projection 212.

[0120] Each side wall 310 of the extractor 300 may have a second recess 311 that is recessed circumferentially from both ends 312. Both ends 312 of the side wall 310 of the extractor 300 may protrude circumferentially beyond the second recess 311. The second recess 311 can be formed on the outer circumferential surface side, but it can also be formed on the inner circumferential surface side. The end 312 of the side wall 310 of the extractor 300 can be called the second projection 312.

[0121] With respect to the radial direction, the first recess 211 and the second projection 312 may be located in corresponding positions to each other. The second projection 312 may be positioned in the first recess 211. With respect to the radial direction, the first projection 212 and the second recess 311 may be located in corresponding positions to each other. The first projection 212 may be positioned in the second recess 311. The second projection 312 may overlap the first projection 212 in the radial direction.

[0122] Therefore, the first projection 212 and the second projection 312 support each other in the radial direction, and the side wall 210 of the heater holder 200 and the side wall 310 of the extractor 300 can be stably positioned relative to each other.

[0123] Such configurations are merely illustrative, and the configurations and methods by which the side walls 210 of the heater holder 200 and the side walls 310 of the extractor 300 interlock in the radial direction are not limited thereto.

[0124] As another example, coupling grooves (not shown) may be formed at both ends of the side wall 210 of the heater holder 200, and coupling protrusions (not shown) that are inserted into the coupling grooves may be formed at both ends of the side wall 310 of the extractor 300. The positions of the coupling grooves and coupling protrusions may be interchangeable. As yet another example, both ends of the side wall 210 of the heater holder 200 and both ends of the side wall 310 of the extractor 300 may be formed in corresponding diagonal lines to support each other radially.

[0125] Figure 15 shows cross-sectional views (a) of the embodiments shown in Figures 2 to 11 and (b) of the embodiments shown in Figures 12 to 14, comparing the thickness of the side walls 21 and 210 of the heater holders 20 and 200 and the side walls 31 and 310 of the extractors 30 and 300, which are positioned between the induction coil 15 and the heater 50, and the distance between the heater 50 and the induction coil 15. Figure 16 compares the power consumed to heat the heater 50 to a predetermined temperature (comparison of consumed current) and the time required to heat the heater 50 to a predetermined temperature (comparison of heating rate) for embodiments (a) and (b) of Figure 15.

[0126] Referring to Figure 15, in embodiment (a), the thickness of the wall formed by the side wall 21 of the heater holder 20 and the side wall 31 of the extractor 30, which are positioned between the induction coil 15 and the heater 50, can be defined as A2. In embodiment (b), the thickness of the wall formed by the side wall 210 of the heater holder 200 and the side wall 310 of the extractor 300, which are positioned between the induction coil 15 and the heater 50, can be defined as B2. In embodiment (a), the wall formed radially by the side wall 21 of the heater holder 20 and the side wall 31 of the extractor 30 is double, while in embodiment (b), the wall formed radially by the side wall 210 of the heater holder 200 and the side wall 310 of the extractor 300 is single. B2 may be smaller than A2. Therefore, the distance B1 between the induction coil 15 and the heater 50 in embodiment (b) may be smaller than the distance A1 between the induction coil 15 and the heater 50 in embodiment (a).

[0127] Therefore, in the case of Example (b), the amount of current consumed to heat the heater 50 to a predetermined temperature can be reduced compared to Example (a) (see Figure 16). Also, in the case of Example (b), the speed at which the heater 50 heats up to a predetermined temperature can be increased compared to Example (a) (see Figure 16).

[0128] Referring to Figures 17 and 18, the heater holder 200 may have one side wall 210. The first slit 214 and the side wall 210 of the heater holder 200 may be formed in positions opposite to each other. The extractor 300 may have one side wall 310. The second slit 314 and the side wall 310 of the extractor 300 may be formed in positions opposite to each other.

[0129] The side wall 310 of the extractor 300 may be formed in a position corresponding to the first slit 214. The side wall 210 of the heater holder 200 may be formed in a position corresponding to the second slit 314. The side wall 310 of the extractor 300 may be positioned at the first slit 214, and the side wall 210 of the heater holder 200 may be positioned at the second slit 314.

[0130] Therefore, cleaning the heater holder 200 and the extractor 300 can be made easier. To further improve ease of cleaning, the first slit 214 and the second slit 314 can also be formed to open in a direction corresponding to the body wing 16.

[0131] The side walls 210 of the heater holder 200 and the side walls 310 of the extractor 300 can define the fourth insertion space 340. The side walls 210 of the heater holder 200 can cover one side of the fourth insertion space 340, and the side walls 310 of the extractor 300 can cover the other side of the fourth insertion space 340. The side walls 210 of the heater holder 200 and the side walls 310 of the extractor 300 can face each other with the fourth insertion space 340 as the center.

[0132] Referring to Figures 1 to 18, an aerosol generating apparatus according to one aspect of the present disclosure includes a body having a first insertion space formed thereon that is open to the top, a heater holder including a side wall that is detachably inserted into the first insertion space, a heater coupled to the heater holder, and an extractor including a side wall that is sized to be inserted into the first insertion space. The side wall of the heater holder and the side wall of the extractor together form a second insertion space that is open to the top, and can be arranged alternately with respect to the perimeter of the second insertion space.

[0133] Furthermore, according to other aspects of this disclosure, the extractor can be detachably inserted into the heater holder.

[0134] Furthermore, according to other aspects of the present disclosure, the heater holder includes a plurality of side walls, and the extractor includes a plurality of side walls that together form the second insertion space. Each of the plurality of side walls of the heater holder may be arranged alternately with a corresponding side wall of the plurality of side walls of the extractor in a circumferential direction around the second insertion space.

[0135] Furthermore, according to another aspect of the present disclosure, adjacent side walls of the heater holder are positioned to form a plurality of first slits, adjacent side walls of the extractor are positioned to form a plurality of second slits, each side wall of the extractor is insertable into the plurality of first slits, and each side wall of the heater holder is insertable into the plurality of second slits.

[0136] Furthermore, according to other aspects of this disclosure, the side walls of the heater holder and the side walls of the extractor can interlock to support each other radially.
