[0023] The embodiments disclosed in this specification will be described in detail below with reference to the attached drawings. For the sake of brevity in the description with reference to the drawings, identical or similar components are given the same reference numeral, and redundant descriptions thereof are omitted.

[0024] The suffixes "module" and "part" used in the following description of the components are solely for the purpose of facilitating the explanation of the specification and have no special meaning or role.

[0025] In this disclosure, things that are well known to those skilled in the art are omitted for the sake of brevity. The accompanying drawings are provided to facilitate the understanding of various technical features, and it should be understood that the embodiments disclosed herein are not limited to the accompanying drawings. Accordingly, this disclosure should be construed to include all modifications, equivalents, and substitutions in addition to those specifically disclosed in the accompanying drawings.

[0026] Terms including ordinal numbers, such as "first," "second," etc., can be used to describe a variety of components, but it should be understood that the components are not limited by such terms. These terms are used solely for the purpose of distinguishing one component from another.

[0027] When we say that one component is "linked" to another, it is understandable that other components may exist in between. On the other hand, when we say that one component is "directly linked" to another, it is understandable that there are no other components in between.

[0028] A singular expression includes plural expressions unless explicitly indicated otherwise in the context.

[0029] 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 open 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 holding the upper end of the stick 200, which is exposed to the outside, in their mouth.

[0030] The heater 50 can heat the stick S. The heater 50 may extend upward in the space into which the stick S is inserted. The heater 50 may be inserted at the bottom of the stick S. The heater 30 may be a resistive heater.

[0031] Battery 101 can supply power to operate the components of the aerosol generator. Battery 101 can supply power to at least one of the control unit 102, sensor 103, induction coil 15, and heater 30. Battery 11 can supply the power necessary for the operation of the display, motor, etc., provided in the aerosol generator.

[0032] 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 battery 101, induction coil 15, and sensor 103. The control unit 102 can control the operation of the display, motor, and other components provided 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.

[0033] Sensor 103 can sense the temperature of heater 30. Control unit 102 can control the temperature of heater 30 based on the temperature of heater 30 sensed by sensor 103. Control unit 102 can transmit information about the temperature of heater 30 sensed by sensor 103 to the user via the user interface.

[0034] The aerosol generator may include an induction coil 15 surrounding a heater 30. The induction coil 15 can cause the heater 30 to generate heat. The heater 30 is a susceptor, and it can generate heat due to a magnetic field generated by an AC current flowing through the induction coil 15. The magnetic field penetrates the heater 30 and can generate eddy currents within it. The current can generate heat in the heater 30. Unlike the illustrated configuration, the heater 30 may be electrically connected to a battery 101. The heater 30 can generate heat directly by receiving current from the battery 101 without the need for the induction coil 15.

[0035] Referring to Figures 2 to 4, the body 10 may have a shape that extends vertically. The body 10 can provide 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 side walls 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 side walls 111 of the body pipe 11 can be said to be the inner walls 111 of the body 10.

[0036] 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 may open upwards. The second insertion space 24 may have a cylindrical shape. The second insertion space 24 may 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 may be coupled to or fixed to the heater holder 20. The pipe 20' can be called a heater holder pipe 20'.

[0037] 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 may open on one side. The third insertion space 34 may have a cylindrical shape. The third insertion space 34 may be defined by the side walls 31 and the bottom wall 32 of the extractor 30. The outer circumferential surface of the extractor 30 may have a cylindrical shape.

[0038] The lower end of the stick S is inserted into the third insertion space 34, and the upper end of the stick S may 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.

[0039] Therefore, the heater 50 can be easily replaced. The size of the insertion spaces 14, 24, and 34 and the heaters 50 placed in the insertion spaces 14, 24, and 34 is very small, which can make replacement difficult, 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.

[0040] Furthermore, foreign matter generated in 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 generator around the heater 50 becomes easier, improving ease of management. In addition, factors that reduce the performance of the heater 50 are reduced, the durability of the heater 50 is improved, and the replacement cycle of the heater 50 can be extended. Furthermore, factors that alter the taste of the stick S can be reduced.

[0041] The lower end of the heater 50 can be fixed to the mount 22. The heater 50 may extend elongated toward the opening of the second insertion space 24. The heater 50 may be formed in a cylindrical shape with its upper end pointed upwards. As another example, the heater 50 may 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 is coupled to the heater holder 20 and capable of heating the stick S inserted into the third insertion space 34.

[0042] The heater holder 20 can be formed on the heater 50 by insert injection molding. The heater holder 20 may have high heat resistance and excellent rigidity. For example, the heater holder 20 may be formed from polyetheretherketone (PEEK). However, the material of the heater holder 20 is not limited to this.

[0043] 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.

[0044] 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 be directly electrically connected to a power source via terminals formed on the heater holder 20 and generate heat by receiving power.

[0045] 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 separated from the heater 50 and therefore can be separated from the extractor 30 more easily. The stick S can also be separated even when the extractor 30 and the heater holder 20 are not separated from each other.

[0046] Furthermore, foreign matter generated in 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 generator around the heater 50 becomes 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 thus extending the replacement cycle of the heater 50. Furthermore, factors that alter the taste of the stick S are reduced.

[0047] 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.

[0048] The side wall 31 of the extractor 30 may be separated inward from the side wall 21 of the heater holder 20. The lower wall 32 of the extractor 30 may be separated upward from the lower wall 22 of the heater holder 20. Air may 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.

[0049] The upper wall 12 of the body 10 may extend horizontally outward from the upper end of the body pipe 11. The upper wall 12 of the body 10 may cover the upper end of the induction coil 15. The outer lateral wall 13 of the body 10 may extend downward from the outer end of the upper wall 12 of the body 10. The outer lateral wall 13 of the body 10 may face the side wall 111 of the body pipe 11. The outer lateral wall 13 of the body 10 may be spaced outward from the body pipe 11. The induction coil 15 may be positioned between the body pipe 11 and the outer lateral wall 13 of the body 10.

[0050] 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 can be provided with an insertion opening 44. The stick S can be inserted into the insertion opening 44. The upper case 40 can 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 can be positioned between the body 10 and the upper case 40.

[0051] 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 alongside the upper wall 12 of the body 10. A cap 45 may be slidably mounted on the upper side of the upper case body 41.

[0052] 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.

[0053] The extractor 30 may be coupled to the upper case 40. The upper end of the extractor 30 may be coupled to the upper case 40, and the lower end of the extractor 30 may protrude below the upper case 40. The extractor 30 may 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.

[0054] The upper end of the extractor 30 may be coupled to the upper case body 41. The extractor 30 may extend downward from the upper case body 41. The extractor 30 may be positioned between a pair of upper case wings 42.

[0055] 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.

[0056] 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.

[0057] 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 outside of the upper case 40, 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.

[0058] The extractor 30 may be provided with engaging projections 37. The engaging projections 37 may protrude outward horizontally from the outer peripheral surface of the upper end of the extractor 30. Multiple engaging projections 37 may be provided. Multiple engaging projections 26 may be arranged spaced apart from each other in the circumferential direction. The engaging projections 37 can be inserted into and engaged with 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.

[0059] 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.

[0060] 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.

[0061] 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 may 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.

[0062] 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 come into contact with the lower surface of the upper case body 41.

[0063] 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.

[0064] 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.

[0065] The first connecting member 27 can be fixed to a first extension 231 that extends longer on one side around the pipe 20' in the portion of the extension 23. 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 arranged is not limited thereto. For example, the first connecting member 27 can be fixed to the pipe 20'.

[0066] 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.

[0067] 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 adjacent to the lower surface of the upper case body 41. However, the position in which the second coupling member 47 is located is not limited to these. For example, the second coupling member 47 may be fixed to the upper case wing 42. As another example, the second coupling member 47 can be fixed to the extractor 30. The second coupling member 47 can be located in a position corresponding to the first coupling member 27.

[0068] An attractive force may act between the second coupling member 47 and 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.

[0069] The third coupling member 17 can be fixed inside the body 10. The third coupling member 17 may be adjacent to the upper wall 12 of the body 10. The third coupling member 17 may 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 may be adjacent to the side wall 111 of the body pipe 11. An attractive force may act between the third coupling member 17 and 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.

[0070] 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 along the circumferential direction, forming angles. 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 may be surrounded by the extractor 30 and pipe 20'. The extractor 30 and pipe 20' can be separated to form an air gap.

[0071] Therefore, by reducing the amount of heat generated by the heater 50 that is transferred to the body pipe 11 (see Figure 3) via the pipe 20', it is possible to reduce overheating of the aerosol generator.

[0072] 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 so as to be inclined downward. The guide portion 25 may extend circumferentially so as to surround the opening of the second insertion space 24.

[0073] 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.

[0074] 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 can form the exterior of the heater 50. The heater rod 51 may extend 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 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 heat 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.

[0075] The heater 50 may include a heating element 52. The heating element 52 may be inserted into the hollow interior of the heater rod 51. The heating element 52 may 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 may 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.

[0076] The heater 50 may include a support 53. The support 53 may be inserted into the hollow of the heater rod 51. The support 53 may be positioned below the heating element 52. The support 53 may be hollow and fixed to the heater rod 51. The support 53 may support the lower part of the heating element 52. The lower end of the support 53 may be supported by the bottom 22a of the mount 22. A hole 22c formed in the center of the mount 22 may be formed during the insert injection molding process of 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 may 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.

[0077] 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 may be inserted into a mount 22. The mount 22 may be integrally coupled to the flange 55 by insert injection molding of the heater holder 20 onto the heater 50.

[0078] The cross-section of the outer surface of the flange 55 may be non-circular. 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.

[0079] 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.

[0080] 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.

[0081] The extension 23 may 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 may be closer to the diameter L0 of the second insertion space 24 than the length of the second extension L2. The first connecting member 47 may have a plate shape. The first connecting member 47 may be fixed horizontally to the first extension 23.

[0082] Referring to Figures 7 to 9, the upper case 40 is separable 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, to which the heater holder 20 is coupled, is separated from the body 10, the heater holder 20 can be separated from the upper case 40.

[0083] As another example, the heater holder 20 may be detachably coupled to the extractor 30. When the extractor 30 is separated from the body, 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.

[0084] 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, either the first coupling member 27 or 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.

[0085] 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.

[0086] The first connecting member 27 may have a plate shape. The first connecting member 47 may 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.

[0087] As another example, the heater holder 20 may be detachably coupled to the upper case 40 by a screw coupling. Here, the heater holder 20 may rotate circumferentially and be separated from or coupled to the upper case 40 by a screw coupling. Alternatively, the heater holder 20 and the upper case 40 may be detachably coupled using fastening screws. As yet another example, the heater holder 20 may be detachably coupled to the upper case 40 by a snap-fit ​​coupling. Here, either the heater holder 20 or the upper case 40 may be provided with coupling hooks, and the other may be provided with grooves into which the hooks are coupled. These are merely examples, and the methods by which the heater holder 20 is detachably coupled to the upper case 40 are not limited to those described above; the heater holder 20 may be detachably coupled to the upper case 40 by a variety of known methods.

[0088] The heater holder 20, coupled to the upper case 40, may protrude downward from the upper case 40. The heater holder 20 may be positioned between a pair of upper case wings 42. The pipe 20' may protrude downward from the upper case body 41 beyond the upper case wings 42. Thus, the heater holder 20 can be easily grasped.

[0089] Therefore, the heater holder 20 can be easily separated from the upper case 40 while still being stably connected to the upper case 40. In addition, the heater 50 can be conveniently replaced.

[0090] 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. Since the stick S inserted inside the extractor 30 is separated from the heater 50, the stick can be separated from the extractor 30 even more easily.

[0091] 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.

[0092] 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.

[0093] 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 may correspond to one side of the upper wall 12 of the body 10, and the second extension 232 may 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 may be larger for the first extension 231 than for the second extension 232.

[0094] The first connecting member 27 may have a plate shape. The first connecting member 27 may 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 may be 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.

[0095] As another example, the heater holder 20 may be detachably connected to the body 10 by a screw connection. Here, the heater holder 20 may rotate circumferentially to separate from or connect to the body 10 by a screw connection. Alternatively, the heater holder 20 and the body 10 may be detachably connected using fastening screws. As yet another example, the heater holder 20 may 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 is connected. This is merely an example, and the methods by which the heater holder 20 is detachably connected to the body 10 are not limited to those described above, and the heater holder 20 may be detachably connected to the body 10 by a variety of known methods.

[0096] The extension 23, which is connected to the body 10, may 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, the heater holder 20 can be easily grasped.

[0097] 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.

[0098] 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. Since the stick S inserted inside the extractor 30 is separated from the heater 50, the stick S can be separated from the extractor 30 even more easily.

[0099] 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.

[0100] 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.

[0101] The attractive forces between the first connecting member 27 and the second connecting member 47 and the attractive forces 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.

[0102] Therefore, when separating the upper case 40 and / or 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 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 be attached to the body 10 more easily, maintaining a more stable connection.

[0103] 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 is separated from the heater 50, making it easier to remove from the extractor 30.

[0104] Referring to Figures 12 and 13, the heater holder 200 may further include heater holder wings 260. The heater holder wings 260 may be formed on the upper part of the heater holder 200. The heater holder wings 260 may extend upward from the extension 23. The heater holder wings 260 may be formed on both sides of the extension 23. Each of a pair of heater holder wings 260 may be formed in a corresponding position between a pair of upper case wings 42. The first coupling member 27 may be positioned on the extension 23 and / or the heater holder wings 260.

[0105] The wing insertion grooves 415 may be formed by the recessing of the sides of the upper case body 41 between a pair of upper case bodies 42. The wing insertion grooves 415 may be formed in pairs at positions corresponding to each of the pair of heater holder wings 260. The wing insertion grooves 415 may have a shape corresponding to the heater holder wings 260. The heater holder wings 260 can be called heater holder grips 260. The wing insertion grooves 415 can be called grip insertion grooves 415 or grip grooves 415.

[0106] When the heater holder 200 is coupled to the upper case 40, the heater holder wing 260 can cover the side of the upper case body 41 between the pair of upper case wings 42. The heater holder wing 260 can be inserted into the wing insertion groove 415. The upper case wings 42 can be exposed to the outside of the upper case 40 between the pair of upper case wings 42.

[0107] Therefore, the heater holder 200 can be separated more easily from the upper case 40. The user can easily separate the upper case 40 and the heater holder 200 by gripping the pair of heater holder wings 260 and pulling them downwards from the upper case 40. The heater holder wings 260 may have outwardly protruding portions or an uneven shape for ease of gripping.

[0108] Referring to Figures 14 to 16, the pipe 210 may open at the top and bottom. The side walls 211 of the pipe 210 may surround the second insertion space 24. The bottom 212 of the pipe 210 may project radially inward from the lower end of the side walls 211 of the pipe 210. The bottom 212 of the pipe 210 may be open.

[0109] The mount 220 can be coupled to the lower end of the pipe 210. The mount 220 can cover an opening formed in the bottom 212 of the pipe 210. A flange 55 formed at the lower end of the heater 50 can be fixed to the mount 220. The heater 50 can protrude from the mount 220 into the second insertion space 24.

[0110] The mount 220 may be detachably coupled to the lower end of the pipe 210. The pipe 210 may include a hook 270. The hook 270 may protrude downward from the bottom 212 of the pipe 210. A pair of hooks 270 may face each other with respect to the pipe 210. The mount 220 may include an engagement portion 227. A pair of engagement portions 227 may be formed in positions corresponding to the hook 270. The engagement portions 227 can be fastened to the hook 270 to detachably couple the mount 220 and the pipe 210. When the mount 220 is coupled to the pipe 210, the hook 270 may be positioned inside the mount 220. For example, the mount 220 may be coupled to the pipe 210 in a detachable snap-fit ​​manner.

[0111] The pipe 210 may include a pipe rim 213. The pipe rim 213 may be formed at the lower end of the pipe 210. The pipe rim 213 may project downward from the bottom 212 of the pipe 210, extending inward from the side wall 211 of the pipe 210. The pipe rim 213 may recess inward from the periphery of the pipe 210. The pipe rim 213 may form a perimeter.

[0112] The mount 220 may include a rim insertion groove 224a that opens upward. The rim insertion groove 224a may be formed by the mount 220 being recessed downward. The rim insertion groove 224a may form a perimeter.

[0113] The mount 220 may include a base 22a, an inner circumferential wall 222, and an outer circumferential wall 223. The base 22a may be disc-shaped. The outer circumferential wall 223 may extend upward from the edge of the base 22a. The outer circumferential wall 223 may extend along the periphery of the base 22a. The inner circumferential wall 222 may extend upward from the base 22a. The inner circumferential wall 222 may be separated inward from the outer circumferential wall 223. A rim insertion groove 224a may be formed between the outer circumferential wall 223 and the inner circumferential wall 222.

[0114] The rim insertion groove 224a may have a shape corresponding to the pipe rim 213. The pipe rim 213 may be inserted into or pressed into the rim insertion groove 224a. The mount 220 may be formed of an elastic material. For example, the mount 220 may be made of a plastic material. As another example, the mount 220 may be made of a rubber material. However, the material of the mount 220 is not limited to these.

[0115] The engaging portion 227 may protrude inward horizontally from the outer peripheral wall 223. The engaging portion 227 may protrude from the outer peripheral wall 223 into the rim insertion groove 224a. The hook 270 may protrude outward horizontally from the pipe rim 213. When the pipe rim 213 is inserted into the rim insertion groove 224a, the hook 270 can be fastened to the engaging portion 227. The hook hole 224b may be formed by opening the bottom 22a of the mount 220 at a position corresponding to the engaging portion 227 and the hook 270. The hook hole 224b may be located below the rim insertion groove 224a. The hook hole 224b may communicate with the rim insertion groove 224a. The hook 270 can be inserted into the hook hole 224b and fastened to the engaging portion 227. When the hook 270 is fastened to the engaging portion 227, the hook hole 224b and the rim insertion groove 224a may expand by elastic deformation. Hook hole 224b can be described as a deformed hole 224b.

[0116] The pipe rim 213 and the rim insertion groove 224a may have shapes that interlock with each other in the circumferential direction. The cross-sections around the pipe rim 213 and around the rim insertion groove 224a may each be formed to be non-circular. For example, the periphery of the pipe rim 213 and the periphery of the rim insertion groove 224a may each include curved and straight sections. However, the shapes of the pipe rim 213 and the rim insertion groove 224a are not limited thereto.

[0117] The outer surface of the outer wall 223 of the mount 220 may be the same as or similar to the periphery of the outer surface of the pipe 210. The outer surface of the outer wall 223 of the mount 220 may be smaller than the periphery of the first insertion space 14.

[0118] The mount 220 may be exposed on the outside of the pipe 210. The outer periphery wall 223 of the mount 220 may surround the lower end of the pipe 210. The mount grip 225 may protrude outward from the outer periphery wall 223 of the mount 220. The mount grip groove 225a may be formed by a recess in the outer periphery wall 223 of the mount 220. The mount grip 225 may protrude horizontally below the mount grip groove 225a. The mount grip 225 and the mount grip groove 225a may be formed offset from the engaging portion 227 and the hook 270. A pair of mount grips 225 may be formed on both sides of the mount 220.

[0119] Therefore, the user can grasp the mount 220 to separate it from the pipe 210 and clean or replace the heater 50 or heating holder 200. For example, the user can grasp the mount grip 225 and bend the mount 220 to separate the mount 220 from the pipe 210 and release the hook fastening.

[0120] Furthermore, the mount 220 can be prevented from rotating circumferentially relative to the pipe 210 during the process of inserting or removing the stick S from the heater 50.

[0121] Referring to Figures 17 and 18, a pair of mounting grips 225 may be formed on both sides of the mount 220 so as to face each other. A pair of engaging portions 227 may be formed on both sides of the mount 220 so as to face each other.

[0122] The direction in which the pair of engaging portions 227 are formed can be described as the axial direction DS or the fixed end direction DS. The direction in which the pair of mounting grips 225 are formed can be described as the grip direction DG. The axial direction DS and the grip direction DG can intersect each other. The axial direction DS and the grip direction DG can be perpendicular to each other.

[0123] Referring to Figure 18, the engaging portion 227 may include a first inclined surface 2271 and a first flat surface 2272. The first inclined surface 2271 may form the upper surface of the engaging portion 227. The first inclined surface 2271 may be inclined inward from the upper end toward the bottom of the engaging portion 227. The first flat surface 2272 may form the lower surface of the engaging portion 227. The first flat surface 2272 may form a surface in the horizontal direction.

[0124] The first flat surface 2272 may project inward along the axial direction DS from the inner surface of the outer circumferential wall 223 of the mount 220. Unlike the illustrated example, the first flat surface 2272 may project inward in a bulging manner along the axial direction DS and may include sections that gradually narrow in the direction of projection.

[0125] Referring to Figure 19, the hook 270 may include a second inclined surface 271 and a second flat surface 272. The second inclined surface 271 may form the bottom surface of the hook 270. The second inclined surface 271 may extend outward and upward from the bottom end of the hook 270. The second flat surface 272 may form the top surface of the hook 270. The second flat surface 272 may form a surface in the horizontal direction. The second flat surface 272 may be formed parallel to the first flat surface 2272.

[0126] The second flat surface 272 may project outward from the pipe rim 213 along the axial direction DS. The second flat surface 272 may include sections that gradually taper in the direction of projection. The second flat surface 272 may have edges that form a curve and gradually taper in the direction of projection. The second flat surface 272 may gradually taper toward both ends along the grip direction DG.

[0127] Referring to Figures 20 and 21, the hook 270 can be fastened to the engagement portion 227. At least one of the hook 270 and the engagement portion 227 may include an inclined surface that guides the outer peripheral wall 223 to expand outward when the hook 270 is fastened to the engagement portion 227. When the hook 270 is fastened to the engagement portion 227, the first inclined surface 2271 and the second inclined surface 271 come into contact with each other, causing the outer peripheral wall 223 of the mount 220 to expand outward, guiding the hook 270 toward the hook hole 224b and fastening to the engagement portion 227. The deformed outer peripheral wall 223 can return to its original state.

[0128] The hook 270 and the engaging portion 227 can be fastened to each other in a snap-fit ​​manner that prevents them from being disassembled by vertical external forces. The first flat surface 2272 and the second flat surface 272 can protrude horizontally toward each other. When the hook 270 is fastened to the engaging portion 227, the first flat surface 2272 and the second flat surface 272 can come into horizontal surface contact with each other. The surface where the first flat surface 2272 and the second flat surface 272 come into contact with each other can be defined as contact surface A. Against a downward external force, the first flat surface 2272 can be supported by the second flat surface 272 at contact surface A.

[0129] Therefore, when the heater 50 is inserted into the stick S, even if the stick S applies a downward external force to the mount 220, it is possible to prevent the mount 220 from detaching downward from the pipe 210.

[0130] The first slide edge 2273 can be defined as the portion that forms an edge at the end of the engaging portion 227, with reference to the direction in which the engaging portion 227 protrudes. The second slide edge 273 can be defined as the portion that forms an edge at the end of the hook 270, with reference to the direction in which the second flat surface 272 protrudes. The first slide edge 2273 and the second slide edge 273 can form the edge of the contact surface A. The first slide edge 2273 can be called the engaging edge 2273. The second slide edge 273 can be called the hook edge 273.

[0131] Either one first slide edge 2273 and either one second slide edge 273 may intersect at two contact points B. The area of ​​the contact surface A may gradually decrease toward both contact points B along the grip direction DG. The first slide edge 2273 may extend from contact point B to the outside of contact surface A. The section in which the first slide edge 2273 extends from contact point B to the outside of contact surface A can be defined as the bending section 2273a. The second slide edge 273 may extend from contact point B to the outside of contact surface A.

[0132] Therefore, when the heater 50 is inserted into or removed from the stick S, the mount 220 and the heater 50 remain firmly fixed to the heater module 200 without being separated, and the mount 220 can be easily separated from the pipe 210 by bending the mount 220 (see Figure 22). This will be explained in more detail later.

[0133] Referring to Figures 21 to 23, a pair of mount grips 225 may be formed at both ends of the mount 220 with respect to the grip direction DG. The mount grips 225 and mount grip grooves 225a may be exposed on the underside of the pipe 210. The mount grip grooves 225a may be located between the bottom 212 of the pipe 210 and the mount grips 225. The user can grasp at least one of the pair of mount grips 225 and pull it downward from the pipe 210. In this case, the mount 220 may bend downward with a pair of hooks 270 and a pair of engaging portions 227 formed in the axial direction DS as fixed ends.

[0134] Figure 23 shows that the bending angle of the mount 220 gradually increases from the fixed end from (a) to (b) and (c). The area of ​​the contact surface A may gradually decrease along the grip direction DG toward both contacts B. When the mount 220 is bent, the bending section 2273a of the first slide edge 2273 extending from contact B to the outside of contact surface A may not experience resistance from the hook 270. Therefore, as the mount 220 bends, the bending section 2273a may bend together with the mount 220 in the direction of the bend. The bending section 2273a slides into contact with the second slide edge 273, and the outer peripheral wall 223 of the mount 220 may extend outward. As the bending angle of the mount 220 increases, the length of the first slide edge 2273 extending from contact B to the outside of contact surface A may gradually increase. As the bending angle of the mount 220 increases, the distance between the two contacts B may decrease.

[0135] Therefore, as the bending angle of the mount 220 increases, the contact surface A between the hook 270 and the engaging portion 227 gradually decreases, and the fastening force between the hook 270 and the engaging portion 227 can gradually decrease until they are separated.

[0136] Therefore, when the heater 50 is inserted into or removed from the stick S, the mount 220 and the heater 50 remain firmly fixed to the heater module 200 without being separated, and the mount 220 can be easily separated from the pipe 210 by bending the mount 220.
