[0018] Singular expressions include plural expressions unless the context clearly indicates otherwise.

[0019] Referring to FIG. 1, the aerosol generating device can include at least one of a battery 11, a control unit 12, a sensor 13, and an induction coil 14. The aerosol generating device can include bodies 10 and 20. At least one of the battery 11, the control unit 12, the sensor 13, and the induction coil 14 can be disposed inside the lower body 10 of the aerosol generating device. The upper body 20 can be coupled to the upper end of the lower body 10 or can be integrally formed with the lower body 10.

[0020] The pipe 40 can be disposed inside the upper body 20. The pipe 40 can form an insertion space S. The insertion space S can be open upward. The pipe 40 can cover the side and bottom of the insertion space S. The stick 400 can be inserted into the insertion space S.

[0021] The induction coil 14 can be provided inside the upper body 20. The induction coil 14 can surround the insertion space S. The heater module 30 can be provided inside the upper body 20. The heater module 30 can be disposed in the insertion space S.

[0022] The induction coil 14 can surround the insertion space S in which the heater module 30 is disposed. The induction coil 14 can surround the heater module 30. The heater module 30 can be heated by a magnetic field generated by an AC current flowing through the induction coil 14. The magnetic field can penetrate the heater module 30 to generate eddy currents inside the heater module 30. The current can generate heat in the heater module 30. Alternatively, the heater module 30 can directly generate heat by receiving current from the battery 11 without the need for the induction coil 14.

[0023] The stick 400 can be inserted into the insertion space S. One end of the stick 400 can be exposed to the outside of the upper body 20. The heater module 30 can be inserted into the stick 400 by passing through the end of the stick 400. The stick 400 can be heated by the heater module 30. The user can inhale air by putting the exposed end of the stick 400 in their mouth.

[0024] The battery 11 can supply power to the components of the aerosol generator. The battery 11 can supply power to at least one of the control unit 12, sensor 13, induction coil 14, and heater module 30. The battery 11 can supply the power necessary for the display, motor, and other components of the aerosol generator to operate.

[0025] The control unit 12 can control the overall operation of the aerosol generator. The control unit 12 can control the operation of at least one of the battery 11, induction coil 14, and sensor 13. The control unit 12 can control the operation of the display, motor, and other components provided in the aerosol generator. The control unit 12 can check the status of each component of the aerosol generator and determine whether the aerosol generator is in an operational state.

[0026] Sensor 13 can sense the temperature of the heater module 30. Sensor 13 may be located adjacent to the heater module 30 or inside the heater module 30. The control unit 12 can control the temperature of the heater module 30 based on the temperature of the heater module 30 sensed by sensor 13.

[0027] Referring to Figure 2, the inner wall 211 of the upper body 20 can surround the pipe 40. The inner wall 211 may be formed to be elongated vertically. The inner wall 211 may extend circumferentially. The induction coil 14 can surround the inner wall 211 of the upper body 20. The induction coil 14 may be positioned between the inner wall 211 and the outer wall 212 of the upper body 20. The upper wall 213 of the upper body 20 can connect the upper end of the inner wall 211 and the upper end of the outer wall 212 and cover the space between the inner wall 211 and the outer wall 212.

[0028] The flange 22 can be connected to the lower part of the inner wall 211. The flange 22 can face the bottom 42 of the pipe 40. The flange 22 can be formed in a direction that intersects the direction in which the inner wall 211 extends. The flange 22 may have a disc shape. The flange 22 can secure the heater rod 31.

[0029] The heater module 30 may include a heater rod 31. The heater rod 31 may have a shape that extends vertically. The heater rod 31 may be formed in a hollow shape. The heater rod 31 may have a cylindrical shape. The upper end of the heater rod 31 may have a shape that gradually tapers to a point on the upper side. The stick 400 may be inserted into the heater rod 31. The heater rod 31 may be inserted into the interior of the stick 400 by passing through the lower end of the stick 400.

[0030] The heater module 30 may include a heater 32. The heater rod 31 can house the heater 32 inside. The heater 32 may be protected by the heater rod 31. The heater 32 may be formed in the shape of a cylindrically wrapped film. The heater 32 can heat the insertion space S. The heater 32 may be a resistive heating heater. The heater 32 can generate heat by receiving current directly from the battery 11. Alternatively, the heater 32 can generate heat by current being induced by the induction coil 32. The heater 32 may be positioned at a height corresponding to the induction coil 14 and surrounded by the induction coil 14. The heater rod 31 may be formed from a material with good rigidity and thermal conductivity. For example, the heater rod 31 may be formed from a ceramic material. The heater 32 generates heat to heat the heater rod 31, and thus the heater rod 31 can transfer heat to the stick 400 inserted into the insertion space S. The heater 32 may be cylindrical with a hollow shape as shown in the figure. However, the heater 32 may be cylindrical with no hollow space, or it may have a shape corresponding to the hollow space of the heater rod 31 so as to fill the hollow space of the heater rod 31. The shape of the heater 32 is not limited thereto.

[0031] The plug 33 can seal the lower part of the heater 32, which is inserted into the hollow of the heater rod 31. The plug 33 can prevent the heater 32 from detaching from the hollow of the heater rod 31. The plug 33 may be made of a heat-resistant material so that even when the heater 32 generates heat, there is little to no deformation or damage due to heat.

[0032] The plug 33 may have a shape that extends vertically. As shown in the figure, the plug 33 may have an inverted "T" shape. In this case, the width a of the lower end of the plug 33 may be greater than the width of the portion of the plug 33 inserted into the hollow of the heater rod 31. The width a of the lower end of the plug 33 may be the same as the width of the outer surface of the heater rod 31. The lower end of the plug 33 can cover the lower end of the heater rod 31. As another example, unlike the one shown, the plug 33 may have an "I" shape.

[0033] Mount 23 may be formed by the flange 22 being recessed downwards. Mount 23 may be formed in the center of the flange 22. Mount 23 may surround the lower end of the heater rod 31. The lower end of the heater rod 31 may be inserted into and secured by the mount 23. Plug 33 may be located between the mount 23 and the lower end of the heater rod 31. The lower end of plug 33 may be inserted into and secured by the mount 23. The lower end of the heater rod 31 and / or the lower end of plug 33 may be fixed to the inside of the mount 23 by a push-in method, or by bonding with an adhesive material, or by insert injection molding. Mount 23 may surround the lower end of the heater rod 31.

[0034] A mounting hole 234 may be formed at the center of the lower end of the mount 23. The mounting hole 234 may be formed by insert injection molding. Alternatively, the mounting hole 234 may be for allowing air to escape when the heater rod 31 and / or plug 33 are pushed in. Regardless of the shape of the plug 33, the width a of the plug 33 may be greater than the width b of the mounting hole 234 of the mount 23. Thus, the lower end of the plug 33 is supported by the lower end of the mount 23, and the plug 33 cannot be detached from the mount 23.

[0035] A flange hole 24 may be formed by the opening of the flange 22. A flange hole 24 may be formed around the mount 23. Multiple flange holes 24 may be provided. Multiple flange holes 24 may be arranged circumferentially around the mount 23. A flange hole 24 may communicate with an external flow path 26. The external flow path 26 can be called a flow path 26.

[0036] Referring to Figures 2 to 4, the pipe 40 may be placed inside a space surrounded by an inner wall 211. The pipe 40 may be coupled to or fixed to the inner wall 211. The pipe 40 may form an insertion space S. The side walls 41 of the pipe 40 may surround the periphery of the insertion space S. The side walls 41 of the pipe 40 may be formed in a hollow cylindrical shape. The top of the insertion space S may be open. The bottom 42 of the pipe 40 may cover the bottom of the insertion space S.

[0037] The bottom 42 of the pipe 40 may have a shape that is recessed downwards. The bottom 42 may be recessed downwards from the insertion space S. The bottom 42 may have a shape that surrounds the lower part of the insertion space S. A diffusion channel 46 surrounded by the bottom 42 may be formed in the lower part of the insertion space S. The bottom 42 may be separated downwards from the support portion 45.

[0038] The bottom 42 of the pipe 40 may have a shape that gradually expands from the bottom to the top. The bottom 42 may be formed to gradually expand from the first hole 43 toward the side wall 41 of the pipe 40. The bottom 42 may extend toward the side wall 41 toward the bottom, gradually narrowing in the radially inward direction.

[0039] The bottom 42 of the pipe 40 may have a bent shape. The bottom 42 may have a center of curvature located in the insertion space S. The bottom 42 may have a dome shape surrounding the diffusion channel 46.

[0040] The first hole 43 may be formed by opening the bottom 42 of the pipe 40. The first hole 43 may communicate with the insertion space S. The first hole 43 may open in the vertical direction. The first hole 43 may have a circular cross-sectional shape. The first hole 43 may be formed at the center of the bottom 42. The first hole 43 may be formed at a position corresponding to the mount 23 or the heater rod 31. The heater rod 31 may protrude from the flange 22 through the first hole 43 into the insertion space S. The diameter of the first hole 43 may be larger than the outer diameter of the heater rod 31.

[0041] The second hole 44 may be formed by opening the bottom 42 of the pipe 40. The second hole 44 may communicate with the insertion space S. The second hole 44 may be formed at the center of the bottom 42 or around the first hole 43. Multiple second holes 44 may be provided. Multiple second holes 44 may be arranged circumferentially around the center of the bottom 42 or the first hole 43. The second hole 44 may have an elongated cross-sectional shape. The second hole 44 may have an inwardly curved cross-sectional shape.

[0042] The bottom 42 of the pipe 40 can be separated upward from the flange 22 to form an external flow path 26. Air can flow through the external flow path 26. The first hole 43 can be separated upward from the flange 22. The first hole 43 can connect the insertion space S and the external flow path 26. The second hole 44 can be separated upward from the flange 22. The second hole 44 can connect the insertion space S and the external flow path 26.

[0043] Therefore, air can be uniformly diffused inside the stick 400. Furthermore, it is possible to prevent substances generated from the stick 400 from adhering to the bottom 42. Details regarding this will be described later.

[0044] The support portion 45 may be adjacent to the upper edge of the bottom portion 42 of the pipe 40. The support portion 45 may be formed between the edge of the bottom portion 42 and the side wall 41 of the pipe 40. The support portion 45 may project inward from the inner circumferential surface of the side wall 41 of the pipe 40. The support portion 45 may extend in the circumferential direction. The support portion 45 may have a ring shape. The support portion 45 may face the insertion space S. The support portion 45 can support the area around the lower end of the stick 400. The stick 400 may be positioned above the diffusion channel 46 by the support portion 45. When the stick 400 is inserted into the insertion space S, the diffusion channel 46 may come into contact with the lower end of the stick 400.

[0045] Therefore, the support portion 45 can limit the insertion range of the stick 400. In addition, it can prevent the edges of the stick 400 from being crushed when the stick 400 is inserted into the insertion space S.

[0046] Referring to Figure 5, the stick 400 may include a medium section 410. The stick 400 may include a cooling section 420. The stick 400 may include a filter section 430. The cooling section 420 may be positioned between the medium section 410 and the filter section 430. The stick 400 may include a wrapper 440. The wrapper 440 may enclose the medium section 410. The wrapper 440 may enclose the cooling section 420. The wrapper 440 may enclose the filter section 430. The stick 400 may have a cylindrical shape.

[0047] The medium section 410 may include a medium 411. The medium section 410 may include a first medium cover 413. The medium section 410 may include a second medium cover 415. The medium 411 may be positioned between the first medium cover 413 and the second medium cover 415. The first medium cover 413 may be positioned at one end of the stick 400. The first medium cover 413 may cover the underside of the medium 411. The second medium cover 415 may cover the upper side of the medium 411. The length of the medium section 410 may be 24 mm. Thus, it is possible to prevent the medium 411 from detaching from the stick 400. The first medium cover 413 is optional.

[0048] The medium 411 can contain substances of various components. The substances contained in the medium may be flavoring substances of various components. The medium 411 may contain 5-30% aerosol generating substances. The medium 411 may be formed from shredded tobacco leaves, granules, reconstituted tobacco leaves, etc. For example, each of the granules may have a size of 0.4 mm to 1.12 mm. The inside of the medium 411 may be filled to about 70% with granules. The medium 411 may be a mixture of granules and reconstituted tobacco leaves, or a mixture of shredded tobacco leaves and reconstituted tobacco leaves. The length L2 of the medium 411 may be 10 mm.

[0049] The first medium cover 413 and the second medium cover 415 can be formed from a heat-resistant material. For example, the first medium cover 413 may be made of acetate. The second medium cover 415 may be made of acetate. The first medium cover 413 may be made of paper. The second medium cover 415 may be made of paper. At least one of the first medium cover 413 and the second medium cover 415 may be made of paper and have a wrinkled shape, creating multiple gaps between them for air to flow. The gaps may be smaller than the size of each granule in the medium 411. The heater rod 30 can be inserted into the medium 411 by passing through the first medium cover 413 (see Figure 7).

[0050] The first medium cover 413 may contain flavoring substances. Airflow passes through the first medium cover 413 and can be accompanied by the flavoring substances contained in the first medium cover 413. In addition, the heater 33 (see Figure 7) can transfer slight heat to the first medium cover 413, heating the flavoring components contained in the first medium cover 413 and generating an aerosol.

[0051] The length L1 of the first medium cover 413 may be shorter than the length L2 of the medium 411. The length L3 of the second medium cover 413 may be shorter than the length L2 of the medium 411. The length L1 of the first medium cover 413 may be designed to an appropriate thickness to support or prevent damage to the medium 411. The length L1 of the first medium cover 413 may be 1 mm or more. The length L1 of the first medium cover 413 may be 4 mm to 10 mm. The length L1 of the first medium cover 413 may be 7 mm. The length L2 of the second medium cover 413 may be 7 mm. Thus, the medium 411 cannot detach from the medium part 410 and the stick 400. In addition, the amount of heat generated from the heater 32 that is transferred to the flange 50 beyond the lower end of the stick 400 can be reduced, preventing thermal deformation between the coupling components and improving structural safety.

[0052] The cooling section 420 may have a cylindrical shape. The cooling section 420 may have a hollow shape. The cooling section 420 may be positioned between the medium section 410 and the filter section 430. The cooling section 420 may be positioned between the second medium section 415 and the filter section 430. The cooling section 420 may be formed in a tubular shape surrounding the internal cooling passage 424. The cooling section 420 may be thicker than the wrapper 440. The cooling section 420 may be made of a paper material thicker than the wrapper 440. The length L4 of the cooling section 420 may be the same as or approximately the same as the length L2 of the medium 411. The length L4 of the cooling section 420 and the cooling passage 424 may be 10 mm. When the stick 400 is inserted into the aerosol generator (see Figures 6 and 7), at least a portion of the cooling section 420 may be exposed to the outside of the aerosol generator.

[0053] Therefore, the cooling unit 420 supports the medium unit 410 and the filter unit 430, ensuring the rigidity of the stick 400. Furthermore, the cooling unit 420 supports the wrapper 440 between the medium unit 410 and the filter unit 430, ensuring the area where the wrapper 440 is bonded. Additionally, heated air and aerosols can be cooled as they pass through the cooling passage 424 inside the cooling unit 420.

[0054] The filter section 430 may be composed of an acetate filter. The filter section 430 may be located at the other end of the stick 400. When the stick 400 is inserted into the aerosol generator (see Figures 6 and 7), the filter section 430 may be exposed to the outside of the aerosol generator. The user can inhale air by holding the filter section 430 in their mouth. The length L5 of the filter section 430 may be 14 mm. The capsule 431 may be located inside the filter section 430. The capsule 431 may contain a flavoring substance. The user can change the flavor of the stick 400 by bursting the capsule 431.

[0055] The wrapper 440 can wrap around or surround the medium portion 410, the cooling portion 420, and the filter portion 430. The wrapper 440 can form the outer shape of the stick 400. The wrapper 440 may be made of paper material. An adhesive portion 441 may be formed on one end of the wrapper 440. The wrapper 440 wraps around the medium portion 410, the cooling portion 420, and the filter portion 430, and the adhesive portion 441 formed on one side edge may be bonded to the other side edge. The wrapper 440 that wraps around the medium portion 410, the cooling portion 420, and the filter portion 430 does not have to cover one end and the other end of the stick 400.

[0056] Therefore, the wrapper 440 can fix the medium section 410, the cooling section 420, and the filter section 430, and prevent them from detaching from the stick 400.

[0057] The first thin film 443 may be positioned in a location corresponding to the first medium cover 413. The first thin film 443 may be positioned between the wrapper 440 and the first medium cover 413, or outside the wrapper 440. The first thin film 443 may surround the first medium cover 413. The first thin film 443 may be made of a metallic material. The first thin film 443 may be made of an aluminum material. The first thin film 443 may be in contact with or coated on the wrapper 440.

[0058] The second thin film 445 may be positioned in a location corresponding to the second medium cover 415. The second thin film 445 may be positioned between the wrapper 440 and the second medium cover 415, or outside the wrapper 440. The second thin film 445 may be made of a metallic material. The second thin film 445 may be made of an aluminum material. The second thin film 445 may be in close contact with or coated on the wrapper 440.

[0059] Therefore, if a capacitance sensor that recognizes the stick is inserted inside the aerosol generator, the capacitance sensor can sense whether the stick 400 has been inserted inside the aerosol generator.

[0060] Referring to Figures 6 and 7, the bottom 42 of the pipe 40 can form a diffusion channel 46 inside by recessing downward from the insertion space S. The diffusion channel 46 may be formed between the lower end of the insertion space S or the lower end of the stick 400 and the bottom 42. The bottom 42 can surround one side of the diffusion channel 46 in a rounded shape. The bottom 42 may have a center of curvature located on the side of the diffusion channel 46. The lower end of the stick 400 can cover the other side of the diffusion channel 46. The diffusion channel 46 can face the medium cover 413 or the medium 411.

[0061] The diffusion channel 46 may have a predetermined height h1 in the vertical direction or in the longitudinal direction of the pipe 40. The height h1 of the diffusion channel 46 may be the height h1 from the first hole 43 to the lower end of the insertion space S or the lower end of the stick 400. The height h2 of the heater 32 from the bottom 42 may be greater than the height h1 of the diffusion channel 46.

[0062] Therefore, when the high-temperature substance generated from the stick 400 falls to the bottom 42, it can cool down quickly as it passes through the diffusion channel 46, preventing the substance from sticking to and solidifying on the bottom 42.

[0063] The first hole 43 may communicate with the diffusion channel 46. The first hole 43 may be adjacent to the center of the diffusion channel 46. The first hole 43 may be formed by opening in the vertical direction. The second hole 44 may communicate with the diffusion channel 46. The second hole 44 may be adjacent to the edge of the diffusion channel 46. Multiple second holes 44 may be arranged in the circumferential direction. The second holes 44 may be inclined with respect to the vertical direction. The second holes 44 may be located below the first hole 43.

[0064] The support portion 45 may protrude inward from the inner circumferential surface of the side wall 41 of the pipe 40. The support portion 45 may protrude in the thickness direction of the side wall 41 of the pipe 40. The support portion 45 may be adjacent to the edge of the diffusion channel 46. The support portion 45 may face the insertion space S. The support portion 45 may be formed outside the second hole 44. The length t1 of the support portion 45 protruding in the thickness direction of the side wall 41 of the pipe 40 may be thicker than the thickness t2 of the wrapper 440.

[0065] Therefore, the support portion 45 can support the lower edge of the stick 400. The support portion 45 can support the wrapper portion 440 of the stick 400. In addition, when the stick 400 is inserted into the insertion space S, it is possible to prevent the edge portion of the stick 400 from being crushed.

[0066] The outer diameter D2 of the medium cover 411 or the medium 413 may be the same as the inner diameter D2 of the wrapper 440 surrounding the stick 400. The inner diameter D1 of the support portion 45 may be smaller than the outer diameter D2 of the medium cover 411 or the medium 413. The inner diameter D1 of the support portion 45 may be smaller than the outer diameter D3 of the stick 400. Thus, air can diffuse to the edge of the medium 413.

[0067] When a user holds the stick 400 in their mouth and inhales air, the air can flow into the external channel 26 through the flange hole 24. From the external channel 26, the air can flow into the diffusion channel 46 through the first hole 43 and / or the second hole 44. The air that has flowed into the diffusion channel 46 can diffuse through the bottom 42 of the pipe 40 to the lower end of the stick 400. The heater 32 can heat the medium 411 to form an aerosol. The air can be supplied to the user along with the aerosol as it passes through the stick 400.
