[0026] Reference Figures 1 to 3 The aerosol-generating device 100 may include at least one of a battery 11 , a controller 12 , and a sensor 13 . The at least one of the battery 11 , the controller 12 , and the sensor 13 may be disposed within the body 10 of the aerosol-generating device 100 .

[0027] The tube 20 may be coupled to the upper side of the body 10 . The tube 20 may have an insertion space 24 therein. The insertion space 24 may be open at the top. The insertion space 24 may have a cylindrical shape. A stick 400 may be detachably inserted into the insertion space 24 .

[0028] The heater 33 may be provided in a heater pin 30 that protrudes upward from the cover 25 toward the insertion space 24, which defines the bottom of the tube 20. The heater 33 may be a resistance heater. The heater 33 may heat the rod 400 inserted into the insertion space 24.

[0029] When the stick 400 is inserted into the insertion space 24, one end of the stick 400 may be exposed to the outside of the insertion space 24 and the body 10. When the stick 400 is inserted into the insertion space 24, the heater 33 may pass through the end of the stick 400 to be inserted into the stick 400. The stick 400 may be heated by the heater 33. The user may inhale air while holding the end of the stick 400 exposed to the outside in his or her mouth.

[0030] The battery 11 may supply power to operate the components of the aerosol-generating device 100. The battery 11 may supply power to at least one of the controller 12, the sensor 13, the induction coil 14, and the heater 33. The battery 11 may supply power required for the operation of a display, a motor, and the like installed at the aerosol-generating device 100.

[0031] The controller 12 may control the overall operation of the aerosol-generating device 100. The controller 12 may control the operation of at least one of the battery 11, the induction coil 14, and the sensor 13.

The controller 12 may check the status of each of the components of the aerosol-generating device 100 to determine whether the aerosol-generating device 100 is in an operable state.

[0032] The sensor 13 may sense the temperature of the heater 33. The controller 12 may control the temperature of the heater 33 based on the temperature of the heater 33 sensed by the sensor 13. The controller 12 may transmit information about the temperature of the heater 33 sensed by the sensor 13 to the user through the user interface. Figure 1, the heater 33 may be electrically connected to the battery 11. The heater 33 may directly generate heat by using the current supplied from the battery 11 without the need for the induction coil 14 (see Figure 2 ).

[0033] Reference Figure 2 The aerosol-generating device 100 may include an induction coil 14. The induction coil 14 may surround the insertion space 24 and the heater 33. The induction coil 14 may cause the heater 33 to generate heat. The heater 33 may be a susceptor that can generate heat through a magnetic field generated by an AC current flowing through the induction coil 14. The magnetic field may pass through the heater 33, thereby generating eddy currents in the heater 33. The current may cause the heater 33 to generate heat.

[0034] Reference Figures 3 to 5 The tube 20 may include a cover 25. The cover 25 may define a bottom of the tube 20 and may cover a lower portion of the insertion space 24. The cover 25 may include a first cover portion 251 and a second cover portion 252.

[0035] A first cover portion 251 may be connected to the lower end of the tube 20. The first cover portion 251 may cover the bottom of the insertion space 24. A second cover portion 252 may be connected to the first cover portion 251. The second cover portion 252 may be formed below the first cover portion 251. The inner surface of the second cover portion 252 may be recessed outward relative to the inner surface of the first cover portion 251. A cover hole 254 may be formed in the lower portion 2522 of the second cover portion 252. The cover hole 254 may communicate with the cavity (or hollow portion) 34 of the heater pin 30.

[0036] The heater pin 30 may extend vertically or vertically. The heater pin 30 may have a cylindrical shape. The heater pin 30 may have a sharp or pointed upper end. The heater pin 30 may have a space for inserting the heater 33. The heater pin 30 may be made of a material having excellent moisture resistance, heat resistance, and thermal conductivity. For example, the heater pin 30 may be made of a ceramic material.

[0037] The heater pin 30 may include a pin body 31. The pin body 31 may extend vertically. The pin body 31 may have a cylindrical shape. A cavity 34 (i.e., a hollow portion) may be defined within the pin body 31. The heater pin 30 may be open at the bottom to communicate with the cavity 34. The cavity 34 may extend vertically. The cavity 34 may have a cylindrical shape.

[0038] The heater pin 30 may include a pin tip 32. The pin tip 32 may define the upper end of the heater pin 30. The pin tip 32 may be integrally formed with the pin body 31. The pin tip 32 may have an upwardly tapering shape. The pin tip 32 may have a sharp or pointed upper end. Thus, the heater pin 30 may pass through the rod S, thereby securing the rod S.

[0039] The flange 35 may protrude outward from the heater pin 30. The flange 35 may protrude in a lateral direction from a lower end of the heater pin 30. The flange 35 may protrude in a radially outward direction from the heater pin 30. The flange 35 may be integrally formed with the heater pin 30.

[0040] The flange 35 may be formed using multiple layers. For example, the flange 35 may be formed using two layers. For example, the flange 35 may include a first flange 351 and a second flange 352. The first flange 351 may be disposed at the upper portion (or top portion) of the flange 35. The second flange 352 may be disposed at the lower portion (or bottom portion) of the flange 35. Hereinafter, the flange 35 will be described as including the first flange 351 and the second flange 352. However, the present disclosure is not limited thereto, and the flange 35 may include a greater number of flanges. For example, the flange 35 may be formed using three or more layers.

[0041] The first flange 351 may be provided on the second flange 352. The first flange 351 may be integrally formed with the second flange 352. The first flange 351 may be provided at a lower portion of the pin body 31. The first flange 351 may protrude laterally outward or radially outward from the outer circumferential surface of the pin body 31. The first flange 351 may extend in the circumferential direction.

[0042] The second flange 352 may be provided below the first flange 351. The second flange 352 may be provided at the lower end of the heater pin 30. The second flange 352 may protrude laterally outward or radially outward from the outer circumferential surface of the pin body 31. The second flange 352 may protrude further laterally outward or radially outward than the first flange 351.

[0043] Therefore, a step (or a step portion) may exist between the first flange 351 and the second flange 352 .

[0044] At least one of the first flange 351 and the second flange 352 may have a non-circular cross-section. For example, the first flange 351 may extend in the circumferential direction to have a circular cross-sectional shape, and the second flange 352 may have a non-circular cross-sectional shape.

[0045] The first cover portion 251 may surround the side surface of the first flange 351 and be in close contact therewith. The first cover portion 251 may cover or be in close contact with the upper surface of the second flange 352. The upper surface of the first flange 351 and the first cover portion 251 may face the bottom of the insertion space 24 together.

[0046] The second cover portion 252 may surround and closely contact the side surface and the outer lower portion of the second flange 352. The second flange 352 may be provided between the first cover portion 251 and the second cover portion 252 to be supported in the up-down direction or the vertical direction.

[0047] Therefore, the cover 25 and the flange 35 can be combined with each other to be engaged in the vertical direction to be supported in the vertical direction. Therefore, the heater pin 30 can be prevented from being separated from the tube 20, and structural stability can be achieved.

[0048] In addition, the cover 25 and the flange 35 may be coupled to each other to engage in the circumferential direction. Therefore, the rotation of the heater pin 30 coupled to the pipe 20 may be prevented (see FIG. Figure 3 ).

[0049] Reference Figure 3 and Figure 6 The heater 33 may have a coil shape. The heater 33 may be wound around an elongated support rod 332. The support rod 332 may support the heater 33 so that the heater 33 maintains its shape.

[0050] The lead wire 331 may be extended longer from each of both ends of the heater 33. The heater 33 may be supplied with power from a power source through the lead wire 331. The heater 33 may be a resistance heater that may generate heat using power supplied thereto.

[0051] The heater 33 and the support rod 332 may be fixed within the heater pin 30 by the first adhesive material 361. The second adhesive material 362 may cover the opening at the bottom of the heater pin 30. The lead wire 331 may pass through the second adhesive material 362 and the cover hole 254 to be exposed downward and may be connected to a power source.

[0052] Reference Figure 7 The first syringe 51 may store the first adhesive material 361 in a liquid state. The first nozzle 511 of the first syringe 51 may have an elongated shape. The first syringe 51 may eject the first adhesive material 361 in a liquid state through the first nozzle 511 .

[0053] First adhesive material 361 can be made of a non-conductive material with excellent heat and chemical resistance. For example, first adhesive material 361 can be a ceramic adhesive (ceramic binder). Ceramic adhesives can include raw materials such as polyurethane, amine, styrene copolymer, resin, etc., but the present disclosure is not limited thereto. Liquid first adhesive material 361 can solidify at room temperature after a predetermined period of time, but this may vary depending on the type of raw materials or the composition ratio of the raw materials constituting first adhesive material 361.

[0054] The heater pin 30 may have an opening at the bottom. When the heater pin 30 is flipped upside down with the opening at the bottom facing upward, a liquid first adhesive material 361 may be injected into the cavity 34 of the heater pin 30 using the first syringe 51. The first nozzle 511 may be inserted into the cavity 34 while spraying the first adhesive material 361 into the cavity 34. The first adhesive material 361 may be injected to a height adjacent to the opening of the heater pin 30. For example, when the heater pin 30 is flipped upside down, the first adhesive material 361 may be injected onto the underside of the flange 35.

[0055] Reference Figure 8 and Figure 9 , when the heater pin 30 is turned upside down, the heater 33 and the support rod 332 can be inserted into the cavity 34 through the opening at the bottom of the heater pin 30. The heater 33 and the support rod 332 can be inserted into the liquid first adhesive material 361 injected into the cavity 34. The support rod 332 and the heater 33 can be completely immersed in the first adhesive material 361. When the heater 33 is wrapped around the support rod 332 and supported by the support rod 332, the shape of the heater 33 can be maintained when inserted into the first adhesive material 361. Here, the lead wire 331 can extend from the heater 33 to the outside of the cavity 34 through the opening of the heater pin 30 to be exposed under the heater pin 30.

[0056] The support rod 332 may be positioned in the cavity 34 parallel to the pin body 31. The heater 33 may be positioned within the cavity 34 between the pin body 31 and the support rod 332. A first adhesive material 361 may fill the gap between the pin body 31, the support rod 332, and the heater 33 in the cavity 34. After the heater 33 and the support rod 332 are inserted into the cavity 34, the first adhesive material 361 may be dried for a predetermined time and cured into a solid state. The first adhesive material 361 may adhere to and secure the inner surface of the pin body 31. The first adhesive material 361 may adhere to and secure the heater 33 and the support rod 332. The first adhesive material 361 may secure or lock the heater 33 and the support rod 332 to the heater pin 30.

[0057] Reference Figure 10 and Figure 11 The second syringe 52 may store the second adhesive material 362 in a liquid state. The second nozzle 521 of the second syringe 52 may have an elongated shape. The second syringe 51 may eject the second adhesive material 361 in a liquid state through the second nozzle 521 .

[0058] Second adhesive material 362 can be made of a non-conductive material with excellent heat and chemical resistance. For example, second adhesive material 362 can be a ceramic adhesive (ceramic binder). Ceramic adhesives can include raw materials such as polyurethane, amine, styrene copolymer, resin, etc., but the present disclosure is not limited thereto. Liquid second adhesive material 362 can solidify at room temperature after a predetermined period of time, but this may vary depending on the type of raw materials or the composition ratio of the raw materials constituting second adhesive material 362.

[0059] When the first adhesive material 361 is dried and solidified and the heater pin 30 is turned upside down so that the opening at the bottom of the heater pin 30 faces upward, the second adhesive material 362 in a liquid state can be injected into the cavity 34 of the heater pin 30. The second nozzle 251 can be inserted into the cavity 34 so as to be adjacent to the opening of the heater pin 30 and spray the second adhesive material 362 into the cavity 34 (i.e., onto the first adhesive material 361). The second adhesive material 362 can be disposed below the first adhesive material 361 (see Figure 3 ).

[0060] The second adhesive material 362 may be injected into the lower end of the heater pin 30. The second adhesive material 362 may fill the opening of the heater pin 30. A portion of the lead 331 may be disposed in the second adhesive material 362. The lead 331 may pass through the second adhesive material 362 to be exposed to the outside of the heater pin 30.

[0061] The second adhesive material 362 may dry and cure into a solid state. The second adhesive material 362 may fill the opening of the heater pin 30 and seal around the opening of the heater pin 30. The second adhesive material 362 may adhere to the inner surface of the heater pin 30 around the opening of the heater pin 30.

[0062] The material of the first adhesive material 361 can be selected by considering the manufacturing efficiency of the heater assembly, errors in manufacturing, and heat transfer, while the material of the second adhesive material 362 can be selected by considering the manufacturing efficiency and moisture resistance of the heater assembly. This is merely an example, and other considerations may be taken into account. Hereinafter, the properties of the first adhesive material 361 and the second adhesive material 362 will be described.

[0063] First adhesive material 361 can be made of a material having low viscosity. Compared to second adhesive material 362, first adhesive material 361 can have a lower viscosity in its liquid state. Therefore, first adhesive material 361 can be easily injected into cavity 34, and heater 33 and support rod 332 can be easily inserted into first adhesive material 361. Furthermore, heater 33 and support rod 332 can be more accurately aligned with respect to heater pin 30.

[0064] The first adhesive material 361 may have high thermal conductivity, while the second adhesive material 362 may have low thermal conductivity. Therefore, the heat generated from the heater 33 can pass through the first adhesive material 361 and the heater pin 30, thereby effectively heating the rod 400 inserted into the insertion space 24. Furthermore, the heat generated from the heater 33 can be insulated by the second adhesive material 362, and the effect on other components disposed below the heater pin 30 can be reduced.

[0065] Compared to first adhesive material 361, second adhesive material 362 may have a higher viscosity and greater adhesive force (or strength) during its liquid state. Therefore, second adhesive material 362 may dry and solidify faster than first adhesive material 361. Furthermore, the adhesive force between second adhesive material 362 and the inner surface of heater pin 30 may be greater than the adhesive force between first adhesive material 361 and the inner surface of heater pin 30. Therefore, second adhesive material 362 may effectively prevent liquid or moisture in the air from entering the interior of heater pin 30.

[0066] Compared to the first adhesive material 361, the second adhesive material 362 may have better moisture resistance and waterproof rating. Moisture resistance can be measured by measuring changes in physical properties over a predetermined period of time under specific temperature and humidity conditions. Water resistance can also be referred to as waterproof rating. Water resistance (defined as the depth of water pressure a material can withstand in water) can be expressed in units of mm. Therefore, even though the aerosol-generating device 100 is exposed to moisture in the air for extended periods, the amount of moisture absorbed by the second adhesive material 362 can be minimal. This prevents moisture from penetrating into the heater pins 30, or reduces the amount of moisture that does penetrate. Compared to the first adhesive material 361, the second adhesive material 362 may have better waterproof properties. Furthermore, malfunction or failure of the heater 33 due to moisture can be prevented, and the temperature of the heater 33 can be more accurately sensed and controlled.

[0067] The first adhesive material 361 and the second adhesive material 362 may each have high heat resistance. The first adhesive material 361 and the second adhesive material 362 may each have a small coefficient of thermal expansion. The heater pin 30, the first adhesive material 361, and the second adhesive material 362 may each be formed of a material that does not thermally deform at the highest temperature of the heater 33 when the heater 33 generates heat.

[0068] Reference Figure 12, the heater pin 30 may further include a recess 353. The recess 353 may be referred to as an outward recess 353. Relative to the lateral or horizontal direction, the inner surface of the heater pin 30 may be recessed outward from the cavity 34 near the opening of the heater pin 30, thereby defining the recess 253. The inner surface of the heater pin 30 may be recessed in a radially outward direction to define the recess 353. The recess 353 may extend in a circumferential direction. The cross-sectional shape of the recess 353 may be circular, but the present disclosure is not limited thereto. Based on the cross-section, the circumference of the recess 353 may be greater than the circumference of the cavity 34.

[0069] The second adhesive material 362 may include a central portion 362a and a protrusion 362b. The second adhesive material 362 in a liquid state may be dried into a solid state to form the central portion 362a aligned with the cavity 34. The central portion 362a may have a cylindrical shape. The second adhesive material 362 in a liquid state may be injected and filled in the recess 353. The liquid second adhesive material 362 injected into the recess 353 may be dried into a solid state. The solid second adhesive material 362 filling the recess 353 may be defined as a protrusion 362b. The protrusion 362b may protrude horizontally from the central portion 362a. The protrusion 362b may protrude radially outward from the central portion 362a. The central portion 362a may protrude vertically farther than the protrusion 362b. The central portion 362a and the protrusion 362b may be bonded to the inner surface of the heater pin 30.

[0070] Therefore, due to the protrusion 362b, a step (or step portion) can be formed in the gap between the central portion 362a and the inner surface of the heater pin 30, thereby preventing liquid from being introduced into the gap between the second adhesive material 362 and the inner surface of the heater pin 30.

[0071] Reference Figure 13 The method of manufacturing the aerosol generating device 100 may include injecting the first adhesive material 361 into the heater pin 30 (S1). In a state where the cavity 34 and the opening of the heater pin 30 are turned upside down, the first nozzle 511 of the first syringe 51 may be inserted into the cavity 34 to inject the first adhesive material 361 (refer to Figure 7 Here, the first adhesive material 361 may be in a liquid state.

[0072] The method of manufacturing the aerosol-generating device 100 may include inserting the heater 33 into the cavity 34 of the heater pin 30 (S2). In step S2, when the first adhesive material 361 is in a liquid state, the heater 33 may be inserted into the cavity 34 and the first adhesive material 34 so that the heater 33 is immersed in the first adhesive material 361. Alternatively, while the heater 33 is being inserted into the cavity 34, the liquid first adhesive material 361 may be injected into the cavity 34. Here, the heater 33 and the support rod 332 may be inserted into the cavity 34 together. When the heater 33 is wrapped around the support rod 332, the heater 33 can stably maintain its shape and be precisely positioned when inserted into the liquid first adhesive material 361.

[0073] The method of manufacturing the aerosol-generating device 100 may include drying the first adhesive material 361 in a liquid state ( S3 ). Here, the liquid first adhesive material 361 may be dried into a solid state and fixed to the heater pin 30 , thereby fixing the heater 33 and the support rod 332 therein.

[0074] The method of manufacturing the aerosol-generating device 100 may include injecting the second adhesive material 362 into the heater pin 30 (S4). In step S4, the cavity 34 and the opening of the heater pin 30 are turned upside down, and the second nozzle 521 of the second syringe 52 is inserted into the cavity 34 to inject the second adhesive material 362 into the cavity 34 adjacent to the opening from above the first adhesive material 361 (see Figures 9 to 11 Here, the second adhesive material 362 may be in a liquid state. In this case, the heater pin 30 may further include the recess 353 described above, and the second adhesive material 362 may be introduced into the recess 353. The lead wire 331 may pass through the second adhesive material 362 to extend to the outside of the heater pin 30.

[0075] The method of manufacturing the aerosol-generating device 100 may include drying the second adhesive material 362 in a liquid state (S5). Here, the liquid second adhesive material 362 may be dried into a solid state to be fixed to the heater pin 30, thereby filling the opening of the heater pin 30. A portion of the lead wire 331 may be fixed by the second adhesive material 362.

[0076] The method of manufacturing the aerosol-generating device 100 may include combining the heater pin 30 and the tube 20 ( S6 ). The tube 20 may be formed by insert injection molding. The tube 20 combined with the heater pin 30 may be manufactured by inserting the heater pin 30, along with the heater 33, the support rod 332, the first adhesive material 361, and the second adhesive material 362, into a mold for injecting the tube 20. The lead wire 331 is then removed from the mold, and the injection material is then injected and cured into the mold.

[0077] Reference Figures 1 to 13 According to one aspect of the present disclosure, an aerosol generating device includes: a main body, including an insertion space; a heater pin, protruding upward from the lower end of the insertion space; a heater, disposed in a cavity of the heater pin; a first adhesive material, injected into the cavity to fix the heater; and a second adhesive material, injected into the cavity to cover the first adhesive material, thereby filling the opening of the cavity.

[0078] The second adhesive material may be better than the first adhesive material in at least water resistance or moisture resistance.

[0079] The second adhesive material may have a higher viscosity and a greater adhesive force during its liquid state than the first adhesive material.

[0080] The second adhesive material may have lower thermal conductivity than the first adhesive material.

[0081] The heater may be wrapped around an elongated support rod inserted into the cavity and secured by the first adhesive material.
