[0027] When an element is said to be "connected" to another element, it will be understood that there can be other elements in between, whereas when an element is said to be "directly connected" to another element, it will be understood that there are no other elements in between.

[0028] The singular expression includes the plural expression unless the context clearly indicates otherwise.

[0029] 1 and 2, the aerosol generating device may include at least one of a battery 101, a controller 102, and a sensor 103. At least one of the battery 101, the controller 102, and the sensor 103 may be disposed inside a body 10 of the aerosol generating device. The body 10 may provide a space that is open at the top so that a stick S can be inserted. The lower end of the stick S may be inserted into the body 10, and the upper end of the stick S may protrude to the outside of the body 10. A user may hold the upper end of the stick 200 exposed to the outside in their mouth to inhale air.

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

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

[0032] The control unit 102 can control the overall operation of the aerosol generation device. The control unit 102 can control the operation of at least one of the battery 101, the induction coil 15, and the sensor 103. The control unit 102 can control the operation of a display, a motor, and the like provided in the aerosol generation device. The control unit 102 can check the state of each component of the aerosol generation device and determine whether the aerosol generation device is in an operable state.

[0033] The sensor 103 may sense the temperature of the heater 30. The control unit 102 may control the temperature of the heater 30 based on the temperature of the heater 30 sensed by the sensor 103. The control unit 102 may transmit information on the temperature of the heater 30 sensed by the sensor 103 to a user through a user interface.

[0034] The aerosol generating device may include an induction coil 15 surrounding the heater 30. The induction coil 15 may cause the heater 30 to generate heat. The heater 30 is a susceptor, and the heater 30 may generate heat due to a magnetic field generated by an AC current flowing through the induction coil 15. The magnetic field may penetrate the heater 30 and generate eddy currents in the heater 30. The current may cause the heater 30 to generate heat. Unlike the one shown in the figure, the heater 30 may be electrically connected to a battery 101. The heater 30 may generate heat directly by receiving a current from the battery 101 without the need for the induction coil 15.

[0035] 2 to 4, the body 10 may have a shape that extends vertically. The body 10 may provide a first insertion space 14 therein. The first insertion space 14 may be open to the upper side. 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 side wall 111 that surrounds the periphery of the first insertion space 14 and a bottom wall 112 that covers 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 wall 111 of the body pipe 11 may be referred to as the inner wall 111 of the body 10.

[0036] The heater holder 20 may be detachably inserted into the first insertion space 14. The heater holder 20 may provide a second insertion space 24 therein. The second insertion space 24 may be open to the upper side. 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 a side wall 21 surrounding the periphery of 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' may be referred to as a bottom 22 or a mount 22. The bottom wall 22 of the pipe 20' may form the bottom 22 of the heater holder 20. The heater 50 may be coupled or fixed to the heater holder 20. The pipe 20' may be referred to as a heater holder pipe 20'.

[0037] The extractor 30 may be detachably inserted into the second insertion space 24. The extractor 30 may provide a third insertion space 34 therein. The third insertion space 34 may be open on one side. The third insertion space 34 may have a cylindrical shape. The third insertion space 34 may be defined by a side wall 31 and a 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 may be inserted into the third insertion space 34, and the upper end of the stick S may protrude outside the aerosol generating device. The heater 50 may heat the first insertion space 14, the second insertion space 24, and the third insertion space 34. The heater 50 may heat the stick S inserted into the third insertion space 34.

[0039] Therefore, it is possible to easily replace the heater 50. Although the size of the insertion spaces 14, 24, 34 and the heaters 50 arranged in the insertion spaces 14, 24, 34 is very small and replacement may be difficult, the user can easily replace the heater 50 by separating the heater holder 20 from the aerosol generating device and placing a new heater holder 20 in the aerosol generating device.

[0040] In addition, foreign matter generated in the stick S does not remain around the heater 50 and in the heater holder 20, but can be extracted through the extractor 30. This makes it easier to clean the aerosol generating device around the heater 50, improving the convenience of management. In addition, factors that reduce the performance of the heater 50 can be reduced, the durability of the heater 50 can be improved, and the replacement cycle of the heater 50 can be extended. In addition, factors that deteriorate the taste of the stick S can be reduced.

[0041] The lower end of the heater 50 may be fixed to the mount 22. The heater 50 may extend long toward the opening of the second insertion space 24. The heater 50 may be formed in a cylindrical shape with an upper end that is pointed upward. As another example, the heater 50 may have a shape that extends in the circumferential direction and be coupled to the side wall 21 of the heater holder 20. However, this is merely an example, and the shape of the heater 50 is not limited to those described above or illustrated, as long as it is coupled to the heater holder 20 and can heat the stick S inserted into the third insertion space 34.

[0042] The heater holder 20 may 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 made of polyetheretherketone (PEEK). However, the material of the heater holder 20 is not limited thereto.

[0043] The through hole 35 may be formed by opening the bottom wall 32 of the extractor 30. The through hole 35 may be open at the top and bottom. When the extractor 30 is inserted into the second insertion space 24, the heater 50 may 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 may be inserted into the bottom of the stick S.

[0044] The induction coil 15 may surround the first insertion space 14. The induction coil 15 may be wound around the side wall 111 of the body pipe 11. The induction coil 15 may surround the heater 50. The induction coil 15 may cause the heater 50 to generate heat. As another example, the heater 50 may be directly electrically connected to a power supply source via a terminal formed on the heater holder 20 and may receive power to generate heat.

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

[0046] In addition, foreign matter generated in the stick S does not remain around the heater 50 and in the heater holder 20, but can be extracted through the extractor 30. This makes it easier to clean the aerosol generating device around the heater 50, improving the convenience of management. In addition, factors that reduce the performance of the heater 50 are reduced, and the durability of the heater 50 is improved, thereby extending the replacement cycle of the heater 50. In addition, factors that deteriorate the taste of the stick S are reduced.

[0047] The heater holder 20 may be disposed 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] A side wall 31 of the extractor 30 may be spaced inward from the side wall 21 of the heater holder 20. A bottom wall 32 of the extractor 30 may be spaced upward from the bottom 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 provided to the stick S inserted into the third insertion space 34.

[0049] The upper wall 12 of the body 10 may extend outward in a horizontal direction from an upper end of the body pipe 11. The upper wall 12 of the body 10 may cover an upper end of the induction coil 15. An outer lateral wall 13 of the body 10 may extend downward from an outer end of the upper wall 12 of the body 10. The outer lateral wall 13 of the body 10 may face a 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 disposed between the body pipe 11 and the outer lateral wall 13 of the body 10.

[0050] The upper case 40 may be detachably coupled to the body 10. The upper case 40 may be coupled to the upper side of the body 10. The upper case 40 may 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 have an insertion opening 44. The stick S may 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 may slide laterally to open and close the insertion opening 44. The heater holder 20 may be disposed between the body 10 and the upper case 40.

[0051] The upper case 40 may include an upper case body 41. The insertion opening 44 may be formed by opening the upper case body 41 at the top and bottom. The insertion opening 44 may be formed at a position offset to one side 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 top wall 12 of the body 10. The lower surface of the upper case body 41 may extend horizontally alongside the top wall 12 of the body 10. A cap 45 may be slidably provided 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. A portion of the side of the upper case body 41 may be exposed between the pair of upper case wings 42 (see FIG. 7 ). The upper case wings 42 may be referred to as upper case grips 42.

[0053] The extractor 30 may be coupled to the upper case 40. An upper end of the extractor 30 may be coupled to the upper case 40, and a 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 opening 44. The insertion opening 44 may be located above the third insertion space 34. The insertion opening 44 may connect the third insertion space 34 to the outside of the aerosol generating device.

[0054] An upper end of the extractor 30 may be coupled to the upper case body 41. The extractor 30 may extend downwardly from the upper case body 41. The extractor 30 may be disposed 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 edges of the top wall 12 of the body 10. The body wings 16 may be formed as a pair facing each other about the top of the body 10 (see FIG. 7). The body wings 16 may be formed at positions offset from the upper case wings 42.

[0056] When the upper case 40 is coupled to the body 10, the upper case 40 may form the exterior of the upper portion of the aerosol generating device. When the upper case 40 is coupled to the body 10, the body wings 16 may cover the sides of the upper case body 41 exposed between the upper case wings 42. When the upper case 40 is coupled to the body 10, the upper case wings 42 may 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 by grasping the exterior of the upper case 40 and separating it from the body 10, 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 include an engagement protrusion 37. The engagement protrusion 37 may protrude outward in a horizontal direction from the outer circumferential surface of the upper end of the extractor 30. A plurality of engagement protrusions 37 may be provided. The plurality of engagement protrusions 26 may be arranged spaced apart from one another in the circumferential direction. The engagement protrusions 37 are 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 engagement protrusions 37 may mesh with the upper case body 41 in the circumferential direction.

[0059] Therefore, during the process of inserting and removing the stick S, the extractor 30 can be prevented from rotating in the circumferential direction relative to the upper case 40.

[0060] The heater holder 20 may include an extension 23. The extension 23 may be formed on the upper end of the heater holder 20. The extension 23 may extend outward in a horizontal direction from the upper end of the pipe 20'. The extension 23 may have a plate shape. The extension 23 may be formed such that one side is longer than the other, with the pipe 20' being the center. The extension 23 may be referred to as 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 horizontally formed 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 may support the extension, and the extension 23 may support the pipe 20'. The pipe 20' may hang down from the extension 23 and be spaced upward from the bottom 112 of the body pipe 11 to form an air gap. The outer circumferential surface of the pipe 20' may be spaced inward from the side wall 111 of the body pipe 11 to form an air gap.

[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 inside the pipe 20′, the extension 23 may come into contact with the lower surface of the upper case body 41.

[0063] The first connecting member 27 may be fixed to the heater holder 20. For example, the first connecting member 27 may be fixed to the extension 23. The first connecting member 27 may be fixed to the inner or outer surface of the extension 23. The heater holder 20 may be insert injection 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 extend 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 in the horizontal direction than the second extension 232. Based on 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 may be defined as the second extension 232. The pipe 20' may extend downward from a portion biased to one side from the center of the extension 23.

[0065] The first connecting member 27 may be fixed to a first extension 231 that extends longer on one side of the pipe 20' at the extension 23. The first connecting member 27 may have a plate shape. The first connecting member 27 may be widely disposed in the horizontal direction on the first extension 23. The position at which the first connecting member 27 is disposed is not limited thereto. For example, the first connecting member 27 may be fixed to the pipe 20'.

[0066] The first connecting member 27 may be made of a magnetic material. The first connecting member 27 may be made of a ferromagnetic material. For example, the first connecting member 27 may be made of stainless steel. However, the material of the first connecting member 27 is not limited thereto.

[0067] The second connecting member 47 may be fixed to the upper case 40. The second connecting member 47 may be fixed inside the upper case body 41. The second connecting member 47 may be adjacent to the lower surface of the upper case body 41. However, the position at which the second connecting member 47 is disposed is not limited thereto. For example, the second connecting member 47 may be fixed to the upper case wing 42. As another example, the second connecting member 47 may be fixed to the extractor 30. The second connecting member 47 may be disposed at a position corresponding to the first connecting member 27.

[0068] An attractive force may act between the second connecting member 47 and the first connecting member 27. For example, the first connecting member 27 may be a ferromagnetic material, and the second connecting member 47 may be a magnet. However, the materials of the first connecting member 27 and the second connecting member 47 are not limited thereto.

[0069] The third connecting member 17 may be fixed inside the body 10. The third connecting member 17 may be adjacent to the upper wall 12 of the body 10. The third connecting member 17 may be disposed at a position corresponding to the first connecting member 27. However, the position at which the third connecting member 17 is disposed is not limited thereto. For example, the third connecting member 17 may be adjacent to the side wall 111 of the body pipe 11. An attractive force may act between the third connecting member 17 and the first connecting member 27. For example, the first connecting member 27 may be a ferromagnetic material, and the third connecting member 17 may be a magnet. However, the materials of the first connecting member 27 and the third connecting member 17 are not limited thereto.

[0070] Referring to FIG. 5, the outer circumferential surface of the sidewall 21 of the pipe 20' may form a plurality of angles in the circumferential direction. The cross section of the outer circumferential surface of the sidewall 21 of the pipe 20' may be polygonal. The outer circumferential surfaces of the sidewall 21 of the pipe 20' may each include a plurality of surfaces that extend vertically and are arranged at angles along the circumferential direction. The outer circumferential surface of the pipe 20' may be spaced inwardly from the sidewall 111 of the body pipe 11 to form an air gap (see FIG. 3). The heater 50 may be surrounded by the extractor 30 and the pipe 20'. The extractor 30 and the pipe 20' may be spaced apart 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 FIG. 3) via the pipe 20', overheating of the aerosol generating device can be reduced.

[0072] 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 disposed between the pipe 20' and the extension portion 23. The guide portion 25 may contact the opening of the second insertion space 24. The guide portion 25 may extend so as to incline downward. The guide portion 25 may extend in the circumferential direction so as to surround the opening of the second insertion space 24.

[0073] Therefore, the guide portion 25 contacts the lower portion of the extractor 30, thereby guiding the extractor 30 so that the extractor 30 can be easily inserted into the second insertion space 24.

[0074] The lower end of the heater 50 may be inserted into and fixed in 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 vertically. The heater rod 51 may have a cylindrical shape. The heater rod 51 may have a hollow that opens to the bottom. The hollow may extend vertically. The internal hollow of 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 upward. The heater rod 51 may have high thermal expansion, excellent 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 thereto.

[0075] The heater 50 may include a heating part 52. The heating part 52 may be inserted into the hollow inside of the heater rod 51. The heating part 52 may extend vertically. The heating part 52 may be formed in a cylindrical shape. The heating part 52 may be made of a resistive metal. Heat generated from the heating part 52 may be transferred to the outside of the heater 50 via the heater rod 51. The heating part 52 may be disposed at a height corresponding to the third insertion space 34 (see FIG. 3). The lower end of the heating part 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 disposed below the heat generating part 52. The support 53 may be hollow and fixed to the heater rod 51. The support 53 may support the lower part of the heat generating part 52. The lower end of the support 53 may be supported by the bottom 22a of the mount 22. The hole 22c formed in the center of the mount 22 may be formed in the process of insert injection molding the heater holder 20. The width of the hole 22c is formed smaller than the width of the support 53, thereby preventing the support 53 from being detached. The hole 22c may be omitted. The support 53 may have high heat resistance. The support 53 may not be thermally deformed by the heat generated by the heat generating part 52. The support 53 may be formed of polyamide. However, the material of the support 53 is not limited thereto.

[0077] The heater 50 may include a flange 55. The flange 55 may be formed on the lower end of the heater rod 51. The flange 55 may extend outward along a horizontal direction from the outer circumferential surface of the lower end of the heater rod 51. The flange 55 may extend in the circumferential direction of the heater rod 51. The lower end of the heater rod 51 and the flange 55 may be inserted into the mount 22. The mount 22 may be integrally joined to the flange 55 by insert injection molding the heater holder 20 into the heater 50.

[0078] The cross section of the outer circumferential surface of the flange 55 may have a non-circular shape. The inner circumferential surface of the mount 22 may have a shape corresponding to the outer circumferential surface of the flange 55. The inner circumferential surface of the mount 22 and the outer circumferential surface of the flange 55 may mesh with each other in the circumferential direction. Therefore, the heater 50 can be prevented from rotating in the circumferential direction relative to the heater holder 20 during the process of separating or inserting the stick S from the heater 50.

[0079] The flange 55 may include a first engagement portion 55a. The first engagement portion 55a may protrude outward from the periphery of the flange 55. The first engagement portion 55a may be formed on a lower portion of the flange 55. The first engagement portion 55a may extend along the periphery of the flange 55.

[0080] The mount 22 may include a second engagement portion 22b. The second engagement portion 22b may protrude inward toward the groove of the mount 22. The second engagement portion 22b may have a shape corresponding to the first engagement portion 55a. The first engagement portion 55a may be located below the second engagement portion 22b. The first engagement portion 55a and the second engagement portion 22b may overlap vertically. The second engagement portion 22a supports the first engagement portion 55a, thereby preventing the flange 55 from coming off the mount 22 upward.

[0081] The extension 23 may extend longer on one side based on the pipe 20' or the second insertion space 24. Based on one horizontal direction, the length L1 of the first extension 231 may be longer than the length of the second extension 232. The length L1 of the first extension 231 may be longer 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] 7 to 9, the upper case 40 is separable from the body 10. The heater holder 20 may be detachably coupled to the upper case 40. When the upper case 40 is separated from the body 10, the heater holder 20 may be separated from the body 10 together with the upper case 40 while still coupled to the upper case 40. When the upper case 40 to which the heater holder 20 is coupled is separated from the body 10, the heater holder 20 may 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 may be separated from the body 10 together with the extractor 30 while still coupled thereto. When the extractor 30 to which the heater holder 20 is coupled is separated from the body 10, the heater holder 20 may be separated from the extractor 30.

[0084] The first connecting member 27 and the second connecting member 47 can exert an attractive force on each other. The first connecting member 27 and the second connecting member 47 can detachably connect the heater holder 20 to the upper case 40 and / or the extractor 30. As an example, the first connecting member 27 and the second connecting member 47 can be magnets that exert an attractive force on each other. As another example, one of the first connecting member 27 and the second connecting member 47 can be a ferromagnetic material, and the other can be a magnet. However, without being limited to the above, the first connecting member 27 and the second connecting member 47 may be configured to exert an attractive force on each other by an electric force or a magnetic force.

[0085] The extension 23 may form a horizontal surface corresponding to the lower surface of the upper case body 41. The first extension 231 may form a horizontal surface corresponding to the lower surface of the upper case body 41. The upper surface of the extension 23 may be supported horizontally by the upper case body 41. The area of ​​the first extension 231 supported by the upper case body 41 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 horizontally fixed to the first extension portion 231. The second connecting member 47 may be disposed adjacent to the lower surface of the upper case body 41. The second connecting member 47 may be formed at a position corresponding to the first connecting member 27. The first extension portion 231 may come into contact with the lower surface of the upper case body 41 due to an attractive force between the first connecting member 27 and the second connecting member 47.

[0087] As another example, the heater holder 20 may be detachably coupled to the upper case 40 by a screw coupling method. Here, the heater holder 20 may be rotated in a circumferential direction and separated or coupled to the upper case 40 by a screw coupling method. Alternatively, the heater holder 20 and the upper case 40 may be detachably coupled to each other by using a fastening screw. As another example, the heater holder 20 may be detachably coupled to the upper case 40 by a snap-fit ​​coupling method. Here, one of the heater holder 20 and the upper case 40 may have a coupling hook, and the other may have a groove to which the hook is coupled. This is merely an example, and the method of detachably coupling the heater holder 20 to the upper case 40 is not limited to the above, and the heater holder 20 may be detachably coupled to the upper case 40 by various 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 disposed 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 gripped.

[0089] Therefore, the heater holder 20 can be easily separated from the upper case 40, but can also be stably coupled to the upper case 40. Also, the heater 50 can be easily replaced.

[0090] In addition, the stick S can be easily separated from the heater 50. A 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 more easily separated from the extractor 30.

[0091] 10 and 11, the heater holder 20 may be detachably coupled to the body 10. With the heater holder 20 coupled to the body 10, the upper case 40 and / or the extractor 30 may be separated from the body 10 and the heater holder 20. With the upper case 40 and / or the extractor 30 separated from the body 10 and the heater holder 20, the heater holder 20 may be separated from the body 10.

[0092] The first and third connecting members 27 and 17 may exert an attractive force on each other. The first and third connecting members 27 and 17 may detachably connect the heater holder 20 to the body 10. As an example, the first and third connecting members 27 and 17 may be magnets that exert an attractive force on each other. As another example, one of the first and third connecting members 27 and 17 may be a ferromagnetic material, and the other may be a magnet. However, the present invention is not limited to the above, and the first and third connecting members 27 and 17 may be configured to exert an attractive force on each other by an electric force or a magnetic force.

[0093] The extension 23 covers the upper wall 12 of the body 10, and the pipe 20' may be inserted into the first insertion space 14. The extension 23 may form a horizontal surface corresponding to the upper wall 12 of the body 10. The first extension 231 may correspond to the upper wall 12 on one side of the body 10, and the second extension 232 may correspond to the upper wall 12 on the other side of the body 10. The lower surface of the extension 23 may be horizontally supported by the upper wall 12 of the body 10. The area supported by the body 10 may be larger in the first extension 231 than in the second extension 232.

[0094] The first connecting member 27 may have a plate shape. The first connecting member 27 may be horizontally fixed to the first extension 231. The third connecting member 17 may be disposed adjacent to the upper wall 12 of the body 10. The third connecting member 17 may be formed at a position corresponding to the first connecting member 27. The first connecting member 27 may be disposed on the first extension 231, and the third connecting member 17 may be disposed adjacent to the upper wall 12 of 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 may come into contact with the upper wall 12 of the body 10.

[0095] As another example, the heater holder 20 may be detachably coupled to the body 10 by a screw coupling method. Here, the heater holder 20 may be rotated in a circumferential direction and separated or coupled to the body 10 by a screw coupling method. Alternatively, the heater holder 20 and the body 10 may be detachably coupled to each other by using a fastening screw. As another example, the heater holder 20 may be detachably coupled to the body 10 by a snap-fit ​​coupling method. Here, one of the heater holder 20 and the body 10 may have a coupling hook, and the other may have a groove to which the hook is coupled. This is merely an example, and the method of detachably coupling the heater holder 20 to the body 10 is not limited to the above, and the heater holder 20 may be detachably coupled to the body 10 by various known methods.

[0096] The extension 23 coupled to the body 10 may be exposed upward from the body 10. The extension 23 may be disposed between a pair of body wings 16. The extension 23 may be disposed adjacent to the outer wall 13 of the body 10 between the pair of body wings 16, or may be disposed in a position parallel to the outer wall 13 above and below. Thus, the heater holder 20 can be easily gripped.

[0097] Therefore, the heater holder 20 can be easily separated from the body 10, but can also be stably attached to the body 10. Also, the heater 50 can be easily replaced.

[0098] In addition, the stick S can be easily separated from the heater 50. A 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 more easily separated from the extractor 30.

[0099] The first connecting member 27 may be disposed between the second connecting member 47 and the third connecting member 17. The first connecting member 27 and the second connecting member 47 may exert an attractive force on each other, and the first connecting member 27 and the third connecting member 17 may exert an attractive force on each other. For example, each of the second connecting member 47 and the third connecting member 17 may be a magnet, and the first connecting member 27 may be a magnet that exerts an attractive force on each of the second connecting member 47 and the third connecting member 17 between the first connecting member 47 and the third connecting member 17. As another example, the first connecting member 27 may be a ferromagnetic material, and each of the second connecting member 47 and the third connecting member 17 may be a magnet. However, the present invention is not limited to the above, and the first connecting member 27 may be configured to exert an attractive force on each of the second connecting member 47 and the third connecting member 17 by an electric force or a magnetic force.

[0100] Therefore, the user can selectively attach the heater holder 20 to either the body 10 or the extractor 30 while separating the upper case 40 and / or the extractor 30 from the body 10. Also, the upper case 40 and / or the extractor 30 can be attached to the body 10 more easily and stably.

[0101] 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.

[0102] Therefore, when the upper case 40 and / or the extractor 30 are separated from the body 10, the heater holder 20 can be separated from the body 10 together. In addition, when the upper case 40 and / or the extractor 30 are coupled to the body 10 with the heater holder 20 coupled to the upper case 40 and / or the extractor 30, the upper case 40 can be more easily coupled to the body 10 by the attractive force between the first coupling member 27 and the third coupling member 17, and a more stable coupled state can be maintained.

[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 the upper case 40 and / or the extractor 30 are separated from the body, the heater holder 20 remains connected to the body 10, and the stick S is separated from the heater 50, so that it can be more easily removed from the extractor 30.

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

[0105] The wing insertion grooves 415 may be formed by depressing a side portion of the upper case body 41 between the pair of upper case bodies 42. The wing insertion grooves 415 may be formed in a pair at positions corresponding to the pair of heater holder wings 260, respectively. The wing insertion grooves 415 may have a shape corresponding to the heater holder wings 260. The heater holder wings 260 may be referred to as heater holder grips 260. The wing insertion grooves 415 may be referred to as 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 may cover the side of the upper case body 41 between the pair of upper case wings 42. The heater holder wing 260 may be inserted into the wing insertion groove 415. The upper case wing 42 may 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 more easily separated from the upper case 40. A 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 downward from the upper case 40. The heater holder wings 260 may have outwardly protruding portions or may have an uneven shape for ease of grip.

[0108] 14 to 16, the pipe 210 may be open at the top and bottom. A side wall 211 of the pipe 210 may surround the periphery of the second insertion space 24. A bottom 212 of the pipe 210 may protrude radially inward from a lower end of the side wall 211 of the pipe 210. The bottom 212 of the pipe 210 may be open.

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

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

[0111] The pipe 210 may include a pipe rim 213. The pipe rim 213 may be formed at a lower end of the pipe 210. The pipe rim 213 may project downwardly from a bottom 212 of the pipe 210 that extends inwardly from a sidewall 211 of the pipe 210. The pipe rim 213 may be recessed inwardly from a perimeter of the pipe 210. The pipe rim 213 may form a perimeter.

[0112] The mount 220 may include a rim insertion groove 224a that is open to the upper side. The rim insertion groove 224a may be formed by recessing the mount 220 to the lower side. The rim insertion groove 224a may form a periphery.

[0113] The mount 220 may include a bottom 22a, an inner peripheral wall 222, and an outer peripheral wall 223. The bottom 22a may have a disk shape. The outer peripheral wall 223 may extend upward from an edge of the bottom 22a. The outer peripheral wall 223 may extend along a periphery of the bottom 22a. The inner peripheral wall 222 may extend upward from the bottom 22a. The inner peripheral wall 222 may be spaced inwardly from the outer peripheral wall 223. The rim insertion groove 224a may be formed between the outer peripheral wall 223 and the inner peripheral 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 or pressed into the rim insertion groove 224a. The mount 220 may be made of a material having elasticity. 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 thereto.

[0115] The engaging portion 227 may protrude inward from the outer peripheral wall 223 along the horizontal direction. The engaging portion 227 may protrude from the outer peripheral wall 223 into the rim insertion groove 224a. The hook 270 may protrude outward from the pipe rim 213 along the horizontal direction. When the pipe rim 213 is inserted into the rim insertion groove 224a, the hook 270 may 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 may 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 due to elastic deformation. The hook hole 224b can be said to be a modified hole 224b.

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

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

[0118] The mount 220 may be exposed to the outside of the pipe 210. The outer peripheral 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 peripheral wall 223 of the mount 220. The mount grip groove 225a may be formed by recessing the outer peripheral 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 at a position offset from the engagement portion 227 and the hook 270. A pair of mount grips 225 may be formed on both sides of the mount 220.

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

[0120] In addition, during the process of inserting or removing the stick S from the heater 50, the mount 220 can be prevented from rotating in the circumferential direction relative to the pipe 210.

[0121] 17 and 18, a pair of mount grips 225 may be formed on both sides of the mount 220, facing each other. A pair of engagement portions 227 may be formed on both sides of the mount 220, opposite each other.

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

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

[0124] The first flat surface 2272 may protrude inwardly along the axial direction DS from the inner circumferential surface of the outer circumferential wall 223 of the mount 220. Unlike what is shown in the figure, the first flat surface 2272 may protrude inwardly along the axial direction DS and may include a section that gradually narrows in the protruding direction.

[0125] 19, the hook 270 may include a second inclined surface 271 and a second flat surface 272. The second inclined surface 271 may form a lower surface of the hook 270. The second inclined surface 271 may extend from a lower end of the hook 270 toward the upper side so as to be inclined outward. The second flat surface 272 may form an upper 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 protrude from the pipe rim 213 in an axial direction DS so as to bulge outward. The second flat surface 272 may include a section that tapers in the protruding direction. The second flat surface 272 may have a curved edge and taper in the protruding direction. The second flat surface 272 may taper toward both ends along the gripping direction DG.

[0127] 20 and 21, the hook 270 may 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, if the first inclined surface 2271 and the second inclined surface 271 contact each other, the outer peripheral wall 223 of the mount 220 may expand outward to guide the hook 270 to be drawn toward the hook hole 224b and fastened to the engagement portion 227. The deformed outer peripheral wall 223 may return to its original state.

[0128] The hook 270 and the engagement portion 227 may be fastened to each other in a snap-fit ​​manner that is not disassembled by an external force in the vertical direction. The first flat surface 2272 and the second flat surface 272 may protrude horizontally toward each other. When the hook 270 is fastened to the engagement portion 227, the first flat surface 2272 and the second flat surface 272 may come into surface contact with each other in the horizontal direction. The surface where the first flat surface 2272 and the second flat surface 272 come into contact with each other may be defined as a contact surface A. With respect to an external force in the downward direction, the first flat surface 2272 may be supported by the second flat surface 272 at the contact surface A.

[0129] Therefore, even if the stick S applies a downward external force to the mount 220 when the heater 50 is inserted into the stick S, the mount 220 can be prevented from coming off the pipe 210 downward.

[0130] The first slide edge 2273 may be defined as a portion that forms an edge at an end of the engaging portion 227 based on the protruding direction of the engaging portion 227. The second slide edge 273 may be defined as a portion that forms an edge at an end of the hook 270 based on the protruding direction of the second flat surface 272. The first slide edge 2273 and the second slide edge 273 may form an edge of the contact surface A. The first slide edge 2273 may be referred to as the engaging edge 2273. The second slide edge 273 may be referred to as the hook edge 273.

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

[0132] Thus, when the heater 50 is inserted into or removed from the stick S, the mount 220 and the heater 50 are firmly fixed without being separated from the heater module 200, and the mount 220 can be easily separated from the pipe 210 by bending the mount 220 (see FIG. 22), which will be described in detail later.

[0133] 21 to 23, a pair of mount grips 225 may be formed on both ends of the mount 220 based on the grip direction DG. The mount grip 225 and the mount grip groove 225a may be exposed to the underside of the pipe 210. The mount grip groove 225a may be located between the bottom 212 of the pipe 210 and the mount grip 225. A user may grip at least one of the pair of mount grips 225 and pull it downward from the pipe 210. At this time, the mount 220 may be bent downward with the pair of hooks 270 and the pair of engagement portions 227 formed in the axial direction DS as fixed ends.

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

[0135] Therefore, as the bending angle of the mount 220 increases, the contact surface A between the hook 270 and the engagement portion 227 becomes smaller, so that the fastening force between the hook 270 and the engagement portion 227 can gradually decrease until they are separated from each other.

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