[0015] When referring to a certain component being "connected" to another component, it can be understood that other components may exist in the middle. On the other hand, when referring to a certain component being "directly connected" to another component, it can be understood that no other components exist in the middle.

[0016] Singular expressions include plural expressions unless otherwise indicated by the context.

[0017] Referring to FIGS. 1 and 2, the aerosol generating device can include at least one of the battery 101 and the control unit 102. At least one of the battery 101 and the control unit 102 can be disposed inside the body 10 of the aerosol generating device. The body 10 can have a shape that extends longitudinally up and down.

[0018] The stick S can be inserted into the body 10. The lower end of the stick S can be inserted into the body 10, and the upper end of the stick S can protrude outside the body 10. The user can inhale air by putting the upper end of the stick 200, which is exposed to the outside, into their mouth. The body 10 may have an insertion space 14 that opens upward so that the stick S can be inserted. A heater 50 can heat the stick S. The heater 50 may be located in the insertion space 14.

[0019] Referring to Figure 1, the aerosol generator may include a heater 50. The heater 50 can protrude upward from the bottom of the insertion space 14. The heater 50 can be detachably coupled to the body 10 (see Figures 5 and 6).

[0020] The heater 50 may include a heater rod 51. The heater rod 51 may form the outer shape (or appearance) of the heater 50. The heater rod 51 may extend long vertically. The heater rod 51 may have a cylindrical shape. The heater rod 51 may have a hollow opening on the lower side. The upper end of the heater rod 51 may be formed to be pointed upwards. The heater rod 51 may have high thermal expansion, excellent thermal insulation, and low thermal conductivity. The heater rod 51 may have high rigidity. For example, the heater rod 51 may be made of zirconia. However, the material of the heater rod 51 is not limited thereto.

[0021] The heater 50 may include a heating element 52. The heating element 52 may be inserted into the hollow space inside the heater rod 51. The heating element 52 may extend vertically. The heating element 52 may have 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.

[0022] Referring to Figure 2, the heating element 52 of the heater 50 can be fixed inside the stick S, and when the stick S is inserted into the insertion space 14, the heater 50 can be positioned in the insertion space 14. When the stick S is removed from the insertion space 14, the heater 50 can be removed from the insertion space 14.

[0023] The aerosol generator may include an induction coil 60 surrounding a heater 50. The induction coil 60 may surround an insertion space 14. The induction coil 60 can cause the heater 50 to generate heat. The heater 50 is a susceptor, and the heating element 52 of the heater 50 can generate heat through a magnetic field generated by an AC current flowing through the induction coil 60. The magnetic field penetrates the heater 50 and can generate eddy currents within the heater 50. The current can cause the heating element 50 to generate heat. The heat generated from the heating element 52 can be transferred to the outside of the heater 50 by passing through a heater rod 51. The induction coil 60 may be positioned at a height corresponding to the heating element 52.

[0024] The induction coil 60 may include an inner coil 61 and an outer coil 62. The inner coil 61 and the outer coil 62 can be wound around the insertion space 14. The outer coil 62 may be positioned outside the inner coil 61. The inner coil 61 and the outer coil 62 can be formed integrally. One end of the inner coil 61 and one end of the outer coil 62 can be connected to each other. The outer coil 62 can extend from one end of the inner coil 61 and be wound around the inner coil 61. The outer coil 62 can be wound in the same direction as the inner coil 61 (see Figure 14). The radius of the outer coil 62 may be greater than the radius of the inner coil 61.

[0025] Therefore, the magnetic field strength can be increased by increasing the number of turns in the coil without increasing its vertical length. Furthermore, since the outer surface of the coil is manufactured flat, the fit with external attachment structures can be improved. This will be discussed later.

[0026] The aerosol generator may include a sensing coil 70. The sensing coil 70 may enclose a portion of the insertion space 14. The sensing coil 70 may be aligned vertically with the induction coil 60. For example, the sensing coil 70 may be positioned below the induction coil 60. As another example, the sensing coil 70 may be positioned above the induction coil 60 (see Figures 17 and 18). To improve sensing sensitivity, the position of the sensing coil 70 may be adjusted taking into account the positions of the heater 50 and the stick S.

[0027] The battery 101 can supply power to the components of the aerosol generator. The battery 101 can supply power to at least one of the control unit 102, heater 50, induction coil 60, and sensing coil 70. The battery 101 can supply the power necessary for the display, motor, etc. installed in the aerosol generator to operate.

[0028] The control unit 102 can control the overall operation of the aerosol generator. The control unit 102 can control the operation of at least one of the following: the battery 101, the heater 50, the induction coil 60, and the sensing coil 70. The control unit 102 can control the operation of displays, motors, and other components installed in the aerosol generator. The control unit 102 can check the status of each component of the aerosol generator and determine whether the aerosol generator is operational. The control unit 102 can receive values ​​sensed by the sensing coil 70 and determine the surrounding conditions.

[0029] Referring to Figures 3 and 4, the control unit 102 can be mounted on the circuit board 80. Alternatively, the circuit board 80 can be electrically connected to another circuit board on which the control unit 102 is mounted. A capacitance sensor 76 can be mounted on the circuit board 80. The capacitance sensor 76 can be connected to the control unit 102. An inductive sensor 77 can be mounted on the circuit board 80. The inductive sensor 77 can be connected to the control unit 102. A switch 75 can be mounted on the circuit board 80. The switch 75 can be connected to either the capacitance sensor 76 or the inductive sensor 77. The switch 75 can switch the connection from either the capacitance sensor 76 or the inductive sensor 77 to the other. The switch 75 can be called a switching element 75. The circuit board 80 can be electrically connected to the battery 101 (see Figures 1 and 2). The control unit 102 can control the operation of the switch 75.

[0030] The sensing coil 70 can be electrically connected to the circuit board 80. The sensing coil 70 can be connected to either the capacitance sensor 76 or the inductance sensor 77 via a switch 75. The switch 75 can release the connection between the sensing coil 70 and the capacitance sensor 76 and connect the sensing coil 70 to the inductance sensor 77. The switch can release the connection between the sensing coil 70 and the inductance sensor 77 and connect the sensing coil 70 to the capacitance sensor 76. The sensing coil 70 can be connected to the capacitance sensor 76 and measure the capacitance value of the surrounding area. The sensing coil 70 can be connected to the inductance sensor 77 and measure the inductance value of the surrounding area. Capacitance and inductance changes may change due to changes in the state of objects surrounding the sensing coil 70. The control unit 102 can sense or determine various states based on the capacitance value. The control unit 102 can sense or determine various states based on the inductance value. The control unit 102 can control the operation of various components of the aerosol generator based on the sensed state.

[0031] For example, in the case of a stick S inserted into the insertion space 14, the humidity (or moisture content) may change depending on the degree of use. In this case, a change in capacitance may occur around the sensing coil 70, and the capacitance value around the sensing coil 70 measured by the capacitance sensor 76 may change. As a result, the control unit 102 can sense the degree of use of the stick S.

[0032] For example, the capacitance values ​​around the sensing coil 70 measured by the capacitance sensor 76 may differ depending on whether or not the stick S is inserted into the insertion space 14. Therefore, the control unit 102 can sense whether or not the stick S is inserted into the insertion space 14.

[0033] For example, the inductance value around the sensing coil 70 measured by the induction sensor 77 may differ depending on whether or not the stick S is inserted into the insertion space 14. Therefore, the control unit 102 can sense whether or not the stick S is inserted into the insertion space 14.

[0034] For example, the internal and external materials contained within the stick S differ depending on the type of stick S inserted into the insertion space 14, and the inductance value around the sensing coil 70 measured by the induction sensor 77 may differ depending on the type of stick S inserted into the insertion space 14. Therefore, the control unit 102 can sense what type of stick S has been inserted into the insertion space 14.

[0035] Since capacitance changes are more sensitive to humidity changes, they are more suitable for recognizing the amount of stick S used. Inductance changes may be more suitable for recognizing a specific stick S. Taking this into consideration, the control unit 102 can control switch 75 so that it connects the capacitance sensor 76 and the sensing coil 70 in order to recognize the amount of stick S used. The control unit 102 can also control switch 75 so that it connects the inductance sensor 77 and the sensing coil 70 in order to recognize the type of stick S.

[0036] The functions of the sensing coil 70 are not limited to those described above; it can be utilized if the surrounding conditions can be determined through elements that cause changes in capacitance or inductance. For this purpose, a lookup table showing the capacitance value around the sensing coil 70 measured by the capacitance sensor 76 and the corresponding changes in the surrounding environment can be stored in memory. Similarly, a lookup table showing the inductance value around the sensing coil 70 measured by the induction sensor 77 and the corresponding changes in the surrounding environment can be stored in memory.

[0037] Therefore, changes in capacitance and inductance can be detected through a single sensor. Furthermore, by separating the region where the induction coil 60 heats the heater 50 from the region where the sensing coil 70 senses, the noise that the induction coil 60 imposes on sensing can be reduced (see Figures 1 and 2). In addition, since it can be positioned more adjacent to the insertion space 14 and the stick S, sensing sensitivity and accuracy can be improved (see Figures 1 and 2).

[0038] Referring to Figures 5 and 6, the body 10 may have a first insertion space 14 inside. The first insertion space 14 may open upwards. The first insertion space 14 may have a cylindrical shape that extends vertically. The first insertion space 14 may be defined by a body pipe 11 formed inside the body 10. The body pipe 11 may include a lateral wall 111 surrounding the first insertion space 14 and a bottom wall 112 covering the bottom of the first insertion space 14. The bottom wall 112 may be formed at the bottom of the body pipe 11. The lateral wall 111 of the body pipe 11 can be called the inner lateral wall 111 of the body 11.

[0039] The heater holder 20 can be detachably inserted into the first insertion space 14. The heater holder 20 may have 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 the bottom 22 or mount 22. The bottom wall 22 of the pipe 20' can form the bottom 22 of the heater holder 20. The heater 50 can be coupled to or fixed to the heater holder 20. The pipe 20' can be called the heater holder pipe 20'.

[0040] The extractor 30 can be detachably inserted into the second insertion space 24. The extractor 30 may have 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.

[0041] The lower end of the stick S is inserted into the third insertion space 34, and the upper end of the stick S can protrude outside the aerosol generator. The heater 50 can heat the first insertion space 14, the second insertion space 24, and the third insertion space 34. The heater 50 can heat the stick S inserted into the third insertion space 34.

[0042] Therefore, the heater 50 can be easily replaced. The size of the insertion spaces 14, 24, and 34 and the heater 50 placed in the insertion spaces 14, 24, and 34 is very small, so replacement may be 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.

[0043] Furthermore, foreign matter generated from the stick S does not remain around the heater 50 or in the heater holder 20, but can be extracted through 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.

[0044] The lower end of the heater 50 can be fixed to the mount 22. The heater 50 can extend elongated toward the opening of the second insertion space 24. The heater 50 can be formed in a cylindrical shape with its upper end pointed upwards. As another example, the heater 50 can have a circumferential shape and be coupled to the side wall 21 of the heater holder 20. However, this is 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 can heat the stick S inserted into the third insertion space 34.

[0045] The heater holder 20 can be insert-injected into the heater 50. The heater holder 20 can have high heat resistance and excellent rigidity. For example, the heater holder 20 can be made of polyetheretherketone (PEEK). However, the material of the heater holder 20 is not limited to this.

[0046] The through-hole 35 can be formed by opening 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.

[0047] The induction coil 60 can surround the first insertion space 14. The induction coil 60 can surround the second insertion space 24. The induction coil 60 can surround the third insertion space 34. The induction coil 60 can be wound around the side wall 111 of the body pipe 11. The induction coil 60 can surround the heater 50. The induction coil 60 can cause the heater 50 to generate heat.

[0048] Therefore, the stick S can be easily separated from the heater 50. The user can easily separate the stick S from the heater 50 by separating the extractor 30 and the heater holder 20 from each other. The stick S, which is inserted inside the extractor 30, can be more easily separated from the extractor 30 once it is separated from the heater 50. The stick S can also be separated even when the extractor 30 and the heater holder 20 are not separated from each other.

[0049] Furthermore, foreign matter generated from the stick S does not remain around the heater 50 or in the heater holder 20, but can be extracted through 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.

[0050] The inner coil 61 and outer coil 62 can be wound around the side wall 111 of the body pipe 11. The outer coil 62 can be positioned outside the inner coil 61. The inner coil 61 and outer coil 62 can surround the heater 50. The outer coil 62 can extend from one end of the inner coil 61. For example, the inner coil 61 can be wound upward around the side wall 111 of the body pipe 11, and the outer coil 62 can extend from the upper end of the inner coil 61 and be wound downward around the inner coil 61.

[0051] Therefore, the magnetic field strength can be increased by increasing the number of turns in the coil without increasing the vertical length of the coil.

[0052] The sensing coil 70 may be positioned below the induction coil 60. The sensing coil 70 may surround the lower part of the first insertion space 14. The sensing coil 70 may surround the lower part of the side wall 111 of the body pipe 11.

[0053] Therefore, it can be positioned closer to the body pipe 11 and the first insertion space 14. Also, since it surrounds the insertion space 14, the sensing range can be increased. Furthermore, the sensing element does not need to pass through the induction coil 60 for sensing. Thus, sensing sensitivity and sensing accuracy can be improved.

[0054] The sensing coil 70 can surround the lower part of the pipe 20' of the heater holder 20. The sensing coil 70 may be positioned adjacent to the lower wall 32 of the extractor 30. The induction coil 60 may be positioned at a height corresponding to the heating element 52. The sensing coil 70 may be positioned at a different height from the heating element 52. For example, the sensing coil 70 may be positioned at a lower height than the heating element 52. The heating element 52 may be positioned higher than the lower wall 32 of the extractor 30.

[0055] 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.

[0056] The side wall 31 of the extractor 30 can be separated inward from the side wall 21 of the heater holder 20. The bottom wall 32 of the extractor 30 can be separated upward from the bottom wall 22 of the heater holder 20. Air can flow between the extractor 30 and the heater holder 20, pass through the through hole 35, and then be supplied to the stick S inserted into the third insertion space 34.

[0057] The upper wall 12 of the body 10 can extend horizontally outward from the upper end of the body pipe 11. The upper wall 12 of the body 10 can cover the upper end of the induction coil 60. The outer lateral wall 13 of the body 10 can extend downward from the outer end of the upper wall 12 of the body 10. The outer lateral wall 13 of the body 10 can face the side wall 111 of the body pipe 11. The outer lateral wall 13 of the body 10 can be spaced outward from the body pipe 11. The induction coil 60 can be positioned between the body pipe 11 and the outer lateral wall 13 of the body 10.

[0058] The upper case 40 can be detachably coupled to the body 10. The upper case 40 can be coupled to the upper side of the body 10. The upper case 40 can cover the periphery of the first insertion space 14 and the periphery of the upper part of the body 10. The upper case 40 may have an insertion opening 44. The stick S can be inserted into the insertion opening 44. The upper case 40 may include a cap 45 for opening and closing the insertion opening 44. The cap 45 can slide laterally to open and close the insertion opening 44. The heater holder 20 may be positioned between the body 10 and the upper case 40.

[0059] The upper case 40 may include an upper case body 41. An insertion opening 44 may be formed by the upper case body 41 opening vertically. The insertion opening 44 may be formed off-center from the center of the upper case body 41. The lower surface of the upper case body 41 may have a shape corresponding to the upper wall 12 of the body 10. The lower surface of the upper case body 41 may extend horizontally parallel to the upper wall 12 of the body 10. A cap 45 may be slidably mounted on the upper side of the upper case body 41.

[0060] 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 sides of the upper case body 41 may be exposed between the pair of upper case wings 42. The upper case wings 42 may be called upper case grips 42.

[0061] The extractor 30 can be coupled to the upper case 40. The upper end of the extractor 30 can be coupled to the upper case 40, and the lower end of the extractor 30 can protrude below the upper case 40. The extractor 30 can be coupled to a position corresponding to the insertion port 44. The insertion port 44 may be located above the third insertion space 34. The insertion port 44 can connect the third insertion space 34 to the outside of the aerosol generator.

[0062] The upper end of the extractor 30 can be coupled to the upper case body 41. The extractor 30 can extend downward from the upper case body 41. The extractor 30 can be positioned between a pair of upper case wings 42.

[0063] The body 10 may include a body wing 16. The body wing 16 may extend upward from the edge of the upper wall 12 of the body 10. The body wing 16 may be formed from a pair of opposing wing wing 16 centered on the upper part of the body 10. The body wing 16 may be formed in a position offset from the upper case wing 42.

[0064] 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.

[0065] 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 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.

[0066] The extractor 30 may be equipped with engaging projections 37. The engaging projections 37 may project horizontally outward from the outer peripheral surface of the upper end of the extractor 30. The engaging projections 37 may include multiple engaging projections. 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.

[0067] 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.

[0068] 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 horizontally outward 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 being longer than the pipe 20'. The extension 23 can be called a heater holder extension 23.

[0069] 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 may support the extension, and the extension 23 may support the pipe 20'. The pipe 20' may hang from the extension 23 and be separated 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 separated inward from the side wall 111 of the body pipe 11 to form an air gap.

[0070] 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 to the lower surface of the upper case body 41. When the upper case 40 is coupled to the body 10, the extension 23 can come into contact with the lower surface of the upper case body 41 as the extractor 30 is inserted into the inside of the pipe 20'.

[0071] 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.

[0072] 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 outer circumference of the first extension 231 may be larger than the outer 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 that is off-center from the center of the extension 23.

[0073] The first connecting member 27 can be fixed to a first extension 231 that extends longer on one side of the extension 23, centered on the pipe 20'. The first connecting member 27 can have a plate shape. The first connecting member 27 can be widely distributed horizontally on the first extension 23. The position in which the first connecting member 27 is positioned is not limited thereto. For example, the first connecting member 27 can also be fixed to the pipe 20'.

[0074] The first coupling member 27 can be made of a magnetic material. The first coupling member 27 may be a ferromagnetic material. For example, the first coupling member 27 can be made of stainless steel. However, the material of the first coupling member 27 is not limited to this.

[0075] The second coupling member 47 can be fixed to the upper case 40. The second coupling member 47 can be fixed inside the upper case body 41. The second coupling member 47 can be positioned adjacent to the lower surface of the upper case body 41. However, the position in which the second coupling member 47 is positioned is not limited to these. For example, the second coupling member 47 can also be fixed to the upper case wing 42. As another example, the second coupling member 47 can also be fixed to the extractor 30. The second coupling member 47 can be positioned in a location corresponding to the first coupling member 27.

[0076] The second coupling member 47 can exert an attractive force on the first coupling member 27. For example, the first coupling member 27 may be a ferromagnetic material, and the second coupling member 47 may be a magnet. However, the materials of the first coupling member 27 and the second coupling member 47 are not limited to these.

[0077] The third coupling member 17 can be fixed inside the body 10. The third coupling member 17 can be positioned adjacent to the upper wall 12 of the body 10. The third coupling member 17 can be positioned in a location corresponding to the first coupling member 27. However, the position in which the third coupling member 17 is positioned is not limited thereto. For example, the third coupling member 17 can be adjacent to the side wall 111 of the body pipe 11. The third coupling member 17 can exert an attractive force on the first coupling member 27. For example, the first coupling member 27 may be a ferromagnetic material and the third coupling member 17 may be a magnet. However, the materials of the first coupling member 27 and the third coupling member 17 are not limited thereto.

[0078] Referring to Figures 4 and 5, the frame 18 may be positioned below the upper body 10a. The frame 18 may be positioned outside the body pipe 11. The frame 18 can support the induction coil 60. The frame 18 can support the sensing coil 70. The induction coil 60 may be positioned above the frame 18. The sensing coil 70 may be positioned above the frame 18.

[0079] The frame 18 may include a first frame 181 and a second frame 182. The second frame 182 may be coupled to the upper side of the first frame 181. The second frame 182 may be surrounded by the upper wall 12, inner wall 111, and outer wall 13 of the upper body 10a. A third coupling member 17 may be positioned between the upper wall 12 of the upper body 10a and the second frame 182. The third coupling member 17 may be fixed to a fixing portion 187 formed on one side of the second frame 182. Part of the first frame 181 may be positioned below the body pipe 11. The other part of the first frame 181 may be inserted into the interior of the second frame 182.

[0080] The coil arrangement space 114 can be defined by the inner wall 111, the upper wall 12, and the outer wall 13 of the upper body 10a. The coil arrangement space 114 can surround the inner wall 111. The coil arrangement space 114 can open to the lower side.

[0081] The induction coil hole 64 is surrounded by the induction coil 60 and may open vertically. The sensing coil holder 74 is surrounded by the sensing coil 70 and may open vertically. The induction coil hole 64 and the sensing coil holder 74 may be aligned vertically. For example, the sensing coil holder 74 may be located below the induction coil hole 64. The frame hole 184 can be formed by opening the second frame 182. The frame hole 184 can be formed below the induction coil hole 64 and the sensing coil holder 74. The induction coil hole 64, the sensing coil holder 74 and the frame hole 184 may have shapes corresponding to the side walls 11 of the body pipe 11. The pipe holder 187 can surround the frame hole 184. The pipe holder 187 can be formed in the frame 18. The pipe holder 187 may have a ring shape. The pipe holder 187 may be part of the second frame 182.

[0082] The body pipe 11 can pass through the induction coil hole 64 and the sensing coil holder 74. When the body pipe 11 passes through the induction coil hole 64 and the sensing coil holder 74, the induction coil 60 and the sensing coil 70 are placed in the coil arrangement space 114, and the body pipe 11 and the first insertion space 14 can be surrounded by the induction coil 60 and the sensing coil 70. The lower perimeter of the body pipe 11 can be inserted into the frame hole 184 and surrounded by the pipe holder 187. The lower perimeter of the body pipe 11 can be supported by the pipe holder 187.

[0083] Referring to Figures 7 and 8, the induction coil 60 is connected to the circuit board 80, its operation is controlled by the control unit 102, and it can receive power from the battery 101. The sensing coil 70 is connected to the circuit board 80, its operation is controlled by the control unit 102, and it can receive power from the battery 101.

[0084] The substrate 80 can be coupled to the frame 18. For example, the substrate 80 can be coupled to one side of the frame 18 via screws 85. The substrate 80 may be positioned vertically elongated on one side of the first frame 181. The substrate 80 may be coupled to the first frame 181 and positioned below the second frame 182.

[0085] The circuit board 80 may include a connector 83. The connector 83 may include a pair of first connectors 831 and a pair of second connectors 832. The first connectors 831 can connect the induction coil 60 to the circuit board 80. Both ends of the induction coil 60 can be electrically connected to each of the pair of first connectors 831. The second connectors 832 can connect the sensing coil 70 to the circuit board 80. Both ends of the sensing coil 70 can be electrically connected to each of the pair of second connectors 832. The connectors 83 may be located on the upper side of the circuit board 80 and adjacent to the lower side of the second frame 182.

[0086] Referring to Figure 9, the splitter 186 may be positioned above the substrate 80 and the connector 83. The splitter 186 can be formed on one side of the frame 18. For example, the splitter 186 may protrude from the pipe holder 187. The splitter 186 can include multiple splitters. Multiple splitters 186 may be arranged spaced apart from each other above the connector 83 around the frame hole 184. Splitter holes 185 can be formed between multiple splitters 186.

[0087] The splitter hole 185 can contain multiple splitter holes. Each of the multiple splitter holes 185 can be formed in a position corresponding to each of the multiple connectors 83. For example, the splitter hole 185 can contain four splitter holes.

[0088] The splitter holes 185 may include a pair of first splitter holes 1851 and a pair of second splitter holes 1852. Each of the pair of first splitter holes 1851 may be located corresponding to the upper side of each of the pair of first connectors 831. Each of the pair of second splitter holes 1852 may be located corresponding to the upper side of each of the pair of second connectors 832.

[0089] The supporter 183 can protrude from the frame 18. The supporter 183 can be formed around the frame hole 184. The supporter 183 can support the induction coil 60.

[0090] Referring to Figures 10 to 12, for convenience, only the body pipe 11 of the upper body 10a (see Figure 7) is shown so that the induction coil 60 and sensing coil 70 are visible. The induction coil 60 and sensing coil 70 can surround the body pipe 11. The sensing coil 70 may be positioned below the induction coil 60.

[0091] The induction coil 60 may include an inner coil 61 and an outer coil 62. The upper end of the inner coil 61 is connected to the upper end of the outer coil 62, and the inner coil 61 and the outer coil 62 can be formed integrally. The inner coil 61 is wound upward around the body pipe 11 in one direction (for example, counterclockwise), and the outer coil 62 extends from the upper end of the inner coil 61 and is wound downward around the inner coil 61 in one direction (for example, counterclockwise). The lower end of the outer coil 62 may be adjacent to the lower end of the inner coil 61. Thus, the body pipe 11 can be wound in a double layer.

[0092] Each of the pair of guide lead wires 631 and 632 can be connected to each of the pair of first connectors 831. Thus, the induction coil 60 can be electrically connected to the substrate 80. Each of the pair of guide lead wires 631 and 632 can extend downward from each of the ends of the induction coil 60. The first guide lead wire 631 can extend downward from the lower end of the inner coil 61. The second guide lead wire 632 can extend downward from the lower end of the outer coil 62. The upper ends of the first guide lead wire 631 and the upper ends of the second guide lead wire 632 can be formed at similar heights.

[0093] In the case of the conventional induction coil 60' shown in Figure 11(a), the pair of induction lead wires 631' and 632' each extend downward from the upper and lower ends of the induction coil 60', respectively. In this case, the length of the induction lead wire 632' extending downward from the upper end becomes excessively long, making it structurally unstable and greatly increasing the risk of wire breakage. Furthermore, because the induction lead wire 632' overlaps the outside of the induction coil and extends downward, the outer shape of the induction coil 60' protrudes radially, resulting in problems with assembly and fit with other structures.

[0094] However, in the present disclosure shown in Figure 11(b), the induction coil 60 comprises an inner coil 61 and an outer coil 62, and of a pair of induction lead wires 631 and 632, the first induction lead wire 631 may extend downward from the lower end of the inner coil 61, and the second induction lead wire 632 may extend downward from the lower end of the outer coil 62. The length L2 of the second induction lead wire 632 may be shorter than the length L2' of the induction lead wire 632' of a conventional induction coil 60'. The length L2 of the second induction lead wire 632 and the length L1 of the first induction lead wire 631 may be similar to each other.

[0095] Therefore, structural safety for the lead wires can be improved, and the risk of wire breakage can be reduced. In addition, the outer shape of the induction coil 60 can be made round to improve assembly and fit with external structures. For example, assembly and structural fit with the outer wall 13 of the upper body 10a (see Figure 7) can be improved. Furthermore, the magnetic field strength can be increased without increasing the vertical length of the induction coil 60.

[0096] Each of the first guide wire 631 and the second guide wire 632 may be positioned to correspond to each of the pair of first splitter holes 1851. Each of the first guide wire 631 and the second guide wire 632 may be positioned to correspond to each of the pair of first terminals 831. The first guide wire 631 can pass through one of the pair of first splitter holes 1851 and be connected to one of the pair of first terminals 831. The second guide wire 632 can pass through the other of the pair of first splitter holes 1851 and be connected to the other of the pair of first terminals 831.

[0097] Each of the pair of sensing lead wires 73 can extend downward from each of the ends of the sensing coil 70. For example, the pair of sensing lead wires 73 may be located between the pair of guide lead wires 631, 632. Each of the pair of sensing lead wires 73 may be located in a position corresponding to each of the pair of second splitter holes 1852. The pair of sensing lead wires 73 may be located in a position corresponding to each of the pair of second terminals 832. Each of the pair of sensing lead wires 73 can pass through each of the pair of second splitter holes 1852 and be connected to each of the pair of second terminals 832. The sensing lead wires 73 can be supported by pipe holders 187 surrounding the lower part of the body pipe 11 (see Figure 13).

[0098] Each of the pair of sensing lead wires 73, the first guide lead wire 631, and the second guide lead wire 632 can be positioned between each of the multiple splitters 186. The splitters 186 can arrange each of the pair of sensing lead wires 73, the first guide lead wire 631, and the second guide lead wire 632 in a separated manner to prevent contact between them. The splitters 186 can support the pair of sensing lead wires 73, the first guide lead wire 631, and the second guide lead wire 632 and fix their respective positions.

[0099] Therefore, contact and interference between lead wires can be prevented. Furthermore, the lead wires can be positioned stably. Additionally, breakage of the lead wires can be prevented.

[0100] Since the induction coil 60 is wound twice around the body pipe 11, the radius of its outer surface can be larger than that of the sensing coil 70 which is wound around the body pipe 11. A predetermined width t can be formed radially between the outer surface of the sensing coil 70 and the outer surface of the induction coil 60. The induction coil 60 can protrude radially by a predetermined width t compared to the sensing coil 70.

[0101] The supporter 183 can support the induction coil 60 and / or the sensing coil 70. For example, the supporter 183 can support the lower part of the outer coil 62. For example, the supporter 183 can support the outer surface of the sensing coil 70. The supporter 183 can separate or isolate the induction coil 60 and the sensing coil 70 so that they do not come into contact with each other.

[0102] In one embodiment, the supporter 183 can be formed on the frame 18. In another example, the supporter 183 can also be formed by protruding outward from the side wall 111 of the body pipe 11 between the induction coil 60 and the sensing coil 70. However, this is only a part of the embodiment, and the location where the supporter 183 is formed is not limited thereto. It can be any location that prevents contact between the induction coil 60 and the sensing coil 70 and supports the induction coil 60 and / or the sensing coil 70.

[0103] The guide wires 631 and 632 can pass outside the sensing coil 70. The guide wires 631 and 632 can be supported by a pipe holder 187 that surrounds the lower part of the body pipe 11 (see Figure 13). The pipe holder 187 (see Figure 13) can be used to separate the guide wires 631 and 632 so that they do not come into contact with the outside of the sensing coil 70.

[0104] Therefore, interference between the induction coil 60 and the sensing coil 70 can be prevented.

[0105] Referring to Figure 14, the induction coil 60 may be positioned at a height corresponding to the heating element 52 of the heater 50. The vertical length L31 of the induction coil 60 may be greater than the vertical length L30 of the heating element 52. The heating element 52 may be located at a height between the upper and lower ends of the induction coil 60.

[0106] The inner coil 61 and the outer coil 62 can be wound in the same direction around the insertion space 14. The vertical lengths of the inner coil 61 and the outer coil 62 may be the same or similar to each other. For example, the vertical length of the inner coil 61 and the vertical length of the outer coil 62 may be L31. The inner coil 61 may be positioned at a height corresponding to the heating element 52. The outer coil 62 may be positioned at a height corresponding to the heating element 52. The number of turns of the outer coil 62 may be the same or similar to the number of turns of the inner coil 61. The number of turns per length of the outer coil 62 may be the same or similar to the number of turns per length of the inner coil 61.

[0107] The sensing coil 70 may be positioned below the induction coil 60. The vertical length L31 of the induction coil 60 may be greater than the vertical length L33 of the sensing coil 70. The sensing coil 70 may be positioned below the heating element 52, at a different height from the heating element 52.

[0108] Therefore, by increasing the number of turns in the induction coil 60 without increasing its vertical length, the strength of the magnetic field affecting the heater 50 can be increased. Furthermore, the region where the induction coil 60 heats the heater 50 and the region where the sensing coil 70 senses can be separated vertically. Additionally, sensing noise can be reduced, and sensing accuracy can be improved.

[0109] Referring to Figure 15, the vertical length L30 of the outer coil 62 may be smaller than the vertical length L31 of the inner coil 61. The vertical length L30 of the outer coil 62 may be the same as or similar to the vertical length L30 of the heating element 52. The outer coil 62 may be positioned at a height between the upper and lower ends of the inner coil 61. The outer coil 62 may be positioned at a height corresponding to the heating element 52. The number of turns of the outer coil 62 may be smaller than the number of turns of the inner coil 61. The number of turns per length of the outer coil 62 may be the same as or similar to the number of turns per length of the inner coil 61.

[0110] Since the induction coil 60 is double-wound around the heater 50, the strength of the magnetic field at the desired location can be increased while reducing the amount of material required to manufacture the induction coil 60.

[0111] Referring to Figure 16, the pitch P1 of the inner coil 61 and the pitch P2 of the outer coil 62 may be different from each other. For example, the pitch P2 of the outer coil 62 may be greater than the pitch P1 of the inner coil 61. The vertical length L32 of the outer coil 62 may be less than the vertical length L31 of the inner coil 61. The number of turns of the outer coil 62 may be less than the number of turns of the inner coil 61. The number of turns per unit length of the outer coil 62 may be less than the number of turns per unit length of the inner coil 61.

[0112] Since the induction coil 60 is double-wound around the heater 50, the strength of the magnetic field at the desired location can be increased, and the amount of material required to manufacture the induction coil 60 can be relatively reduced.

[0113] Referring to Figures 17 and 18, the sensing coil 70 may be positioned above the induction coil 60. The sensing coil 70 may be positioned above the heating element 52 at a different height from the heating element 52. If the extractor 30 supports the stick S, the sensing coil 70 may be positioned higher than the lower wall 32 of the extractor 30. For example, the lower end of the heating element 52 may be adjacent to the lower wall 32 of the extractor 30, and the sensing coil 70 may be positioned higher than both the lower wall 32 of the extractor 30 and the upper end of the heating element 52.

[0114] A pair of sensing lead wires 73 can extend downward from both ends of the sensing coil 70 and pass outside the induction coil 60. Therefore, it is possible to prevent the sensing lead wires 73 from being heated by the induction coil 60.
