[0025] A singular expression includes plural expressions unless explicitly indicated otherwise in the context.

[0026] Referring to Figures 1 to 3, the aerosol generator may include at least one of the battery 11, the control unit 12, and the sensor 13. At least one of the battery 11, the control unit 12, and the sensor 13 may be located inside the body 10 of the aerosol generator.

[0027] The pipe 20 can be connected to the upper side of the body 10. An insertion space 24 can be formed inside the pipe 20. The insertion space 24 can open upwards. The insertion space 24 can be formed in a cylindrical shape. The stick 400 can be detachably inserted into the insertion space 24.

[0028] The heater 33 may be located inside a heater pin 30 that protrudes upward toward the insertion space 24 from a cover 25 forming the bottom of the pipe 20. The heater 33 may be a resistive heater. The heater 33 can heat the stick 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 can 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 can be inserted into the inside of the stick 400 by passing through the end of the stick 400. The stick 400 can be heated by the heater 33. The user can inhale air by putting the exposed end of the stick 400 in their mouth.

[0030] 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 rod 30. The battery 11 can supply the power necessary for the display, motor, etc. installed in the aerosol generator to operate.

[0031] 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 displays, motors, and other components installed 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 operational.

[0032] Sensor 13 can sense the temperature of heater 33. The control unit 12 can control the temperature of heater 33 based on the temperature sensed by sensor 13. The control unit 12 can transmit information about the temperature of heater 33 sensed by sensor 13 to the user via the user interface.

[0033] Referring to Figure 1, the heater 33 can be electrically connected to the battery 11. The heater 33 can directly generate heat by receiving current from the battery 11 without the need for the induction coil 14 (see Figure 2).

[0034] Referring to Figure 2, the aerosol generator 100 may include an induction coil 14. The induction coil 14 can surround the insertion space 24 and the heater 33. The induction coil 14 can cause the heater 33 to generate heat. The heater 33 is a susceptor, and the heater 33 can generate heat due to the magnetic field generated by the AC current flowing through the induction coil 14. The magnetic field penetrates the heater 33 and can generate eddy currents within the heater 33. The current can generate heat in the heater 33.

[0035] Referring to Figures 3 to 5, the pipe 20 may be equipped with a cover 25. The cover 25 forms the bottom of the pipe 20 and can cover the lower part of the insertion space 24. The cover 25 may be equipped with a first cover portion 251 and a second cover portion 252.

[0036] The first cover portion 251 can be connected to the lower end of the pipe 20. The first cover portion 251 can cover the bottom of the insertion space 24. The second cover portion 252 can be connected to the first cover portion 251. The second cover portion 252 can be formed on the underside of the first cover portion 251. The inner surface of the second cover portion 252 can be recessed outward more than the inner surface of the first cover portion 251. A cover hole 254 can be formed inside the lower part 2522 of the second cover portion 252. The cover hole 254 can communicate with the hollow 34 of the heater pin 30.

[0037] The heater pin 30 can extend vertically. The heater pin 30 may have a cylindrical shape. The upper end of the heater pin 30 may be formed to be pointed. The heater pin 30 may have a space inside into which a heater 33 can be inserted. The heater pin 30 can be manufactured from a material with excellent moisture resistance, heat resistance, and thermal conductivity. For example, the heater pin 30 can be manufactured from a ceramic material.

[0038] The heater pin 30 may include a pin body 31. The pin body 31 may extend long in the vertical direction. The pin body 31 may have a cylindrical shape. The pin body 31 may have a hollow interior 34. The lower part of the heater pin 30 can be open and communicate with the hollow 34. The hollow 34 may extend long in the vertical direction. The hollow 34 may have a cylindrical shape.

[0039] The heater pin 30 may include a pin tip 32. The pin tip 32 may form the upper end of the heater pin 30. The pin tip 32 may be formed integrally with the pin body 31 on the upper side of the pin body 31. The pin tip 32 may have a shape that gradually tapers towards the top. The pin tip 32 may have a pointed upper end. Thus, the heater pin 30 can penetrate the stick S and secure the stick S.

[0040] The flange 35 can project outward from the heater pin 30. The flange 35 can project sideways from the lower end of the heater pin 30. The flange 35 can project radially outward from the heater pin 30. The flange 35 can be formed integrally with the heater pin 30.

[0041] The flange 35 may be formed in multiple stages. For example, the flange 35 may be formed in two stages. For example, the flange 35 may include a first flange 351 and a second flange 352. The first flange 351 may be located on the upper part of the flange 35. The second flange 352 may be located on the lower part of the flange 35. Hereinafter, the first flange 351 and the second flange 352 The flange 35 described here includes, but is not limited to, a flange 35. The flange 35 may include a greater number of flanges. For example, the flange 35 may be formed with three or more steps.

[0042] The first flange 351 may be positioned above the second flange 352. The first flange 351 may be formed integrally with the second flange 352. The first flange 351 may be positioned below the pin body 31. The first flange 351 may project outward or radially outward from the outer circumferential surface of the pin body 31. The first flange 351 may extend circumferentially.

[0043] The second flange 352 may be positioned below the first flange 351. The second flange 352 may be positioned at the lower end of the heater pin 30. The second flange 352 may project outward or radially outward from the outer circumferential surface of the pin body 31. The second flange 352 may project further outward or radially outward than the first flange 351.

[0044] Therefore, there may be a step between the first flange 351 and the second flange 352.

[0045] 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 circumferentially and have a circular cross-sectional shape, while the second flange 352 may have a non-circular cross-section.

[0046] The first cover portion 251 can surround and tightly adhere to the side surface of the first flange 351. The first cover portion 251 can cover or tightly adhere to the upper surface of the second flange 352. The upper surface of the first flange 351 can face the bottom of the insertion space 24 together with the first cover portion 251.

[0047] The second cover portion 252 can surround and tightly adhere to the side and outer lower part of the second flange 352. The second flange 352 can be positioned between the first cover portion 251 and the second cover portion 252 and supported in the vertical direction.

[0048] Therefore, the cover 25 and the flange 35 are joined so as to interlock in the vertical direction and are supported in the vertical direction, which prevents the heater pin 30 from detaching from the pipe 20 and ensures structural safety.

[0049] Furthermore, the cover 25 and the flange 35 can be joined so that they interlock in the circumferential direction. This prevents the heater pin 30, which is connected to the pipe 20, from rotating (see Figure 3).

[0050] Referring to Figures 3 to 6, the heater 33 may have a coil shape. The heater 33 can be wound around a long support bar 332. The support bar 332 can support the heater 33 and maintain its shape.

[0051] The lead wires 331 can extend long from both ends of the heater 33. The heater 33 can receive power from a power source via the lead wires 331. The heater 33 is a resistive heater and can generate heat when powered.

[0052] The heater 33 and support bar 332 can be fixed inside the heater pin 30 by the first bonding material 361. The second bonding material 362 can close the opening at the bottom of the heater pin 30. The lead wire 331 is connected to the second bonding material 3 62 and are exposed on the underside through cover hole 254 and can be connected to a power source.

[0053] Referring to Figure 7, the first injector 51 can store the first bonding material 361 in a liquid state inside. The first nozzle 511 of the first injector 51 may have an elongated shape. The first injector 51 can inject the first bonding material 361 in a liquid state through the first nozzle 511.

[0054] The first bonding material 361 is non-conductive and can be formed from a material with excellent heat resistance and chemical resistance. For example, the first bonding material 361 can be a ceramic adhesive. It may be a bonding. The ceramic adhesive may contain, but is not limited to, raw materials such as polyurethane, amine, styrene copolymer and resin. The first bonding material 361 in a liquid state can solidify at room temperature after a predetermined time, but this may vary depending on the type of raw materials or the component ratio of the raw materials that make up the first bonding material 361.

[0055] The heater pin 30 can open on its lower side. With the heater pin 30 inverted so that its lower opening faces upward, the liquid first bonding material 361 can be injected into the internal hollow 34 of the heater pin 30 via the first injector 51. With the first nozzle 511 inserted into the hollow 34, the first bonding material 361 can be sprayed into the hollow 34. The first bonding material 361 can be injected to a height close to the opening of the heater pin 30. For example, the first bonding material 361 can be injected up to the lower side of the flange 35 with respect to the inverted heater pin 30.

[0056] Referring to Figures 8 and 9, the heater 33 and support bar 332 can be inserted into the hollow 34 through an opening formed on the underside of the heater pin 30, with the heater pin 30 covered. The heater 33 and support bar 332 can be inserted into the liquid first bonding material 361 poured into the hollow 34. The support bar 332 and heater 33 can be completely immersed in the first bonding material 361. Here, the heater 33 is wound around the support bar 332 and supported by the support bar 332 so that it can maintain its shape when inserted into the first bonding material 361. Here, the lead wire 331 can extend from the heater 33 to the outside of the hollow 34 through the opening of the heater pin 30 and be exposed on the underside of the heater pin 30.

[0057] The support bar 332 may be positioned parallel to the pin body 31 within the hollow 34. The heater 33 may be positioned between the pin body 31 and the support bar 332 within the hollow 34. The first bonding material 361 can fill the gap between the pin body 31, the support bar 332 and the heater 33 within the hollow 34. After the heater 33 and the support bar 332 are inserted into the hollow 34, the first bonding material 361 can dry and harden for a predetermined time, becoming a solid. The first bonding material 361 can be bonded and fixed to the inner surface of the pin body 31. The first bonding material 361 can be bonded and fixed to the heater 33 and the support bar 332. The first bonding material 361 can fix the heater 33 and the support bar 332 to the heater pin 30.

[0058] Referring to Figures 10 and 11, the second injector 52 can store the second bonding material 362 in a liquid state inside. The second nozzle 521 of the second injector 52 may have an elongated shape. The second injector 52 can inject the second bonding material 362 in a liquid state through the second nozzle 521.

[0059] The second bonding material 362 is non-conductive and can be formed from a material with excellent heat resistance and chemical resistance. For example, the second bonding material 362 can be a ceramic adhesive. Ceramic adhesives can be polyurethane, amines, or styrene. The material may include, but is not limited to, copolymers and resins. The liquid second bonding material 362 can solidify at room temperature after a predetermined time, but this may vary depending on the type of raw materials and the component ratio of the raw materials that make up the second bonding material 362.

[0060] Once the first bonding material 361 has dried and solidified, and with the heater pin 30 covered so that the lower opening of the heater pin 30 faces upward, the liquid second bonding material 362 can be injected into the internal hollow 34 of the heater pin 30 through the second injector 52. The second nozzle 521, inserted into the hollow 34 adjacent to the opening, can spray the second bonding material 362 into the hollow 34, i.e., onto the first bonding material 361. The second bonding material 362 may be positioned below the first bonding material 361 (see Figure 3).

[0061] The second bonding material 362 can be injected up to the lower end of the heater pin 30. The second bonding material 362 can fill the opening of the heater pin 30. A portion of the lead wire 331 can be placed in the second bonding material 362. The lead wire 331 can pass through the second bonding material 362 and be exposed to the outside of the heater pin 30.

[0062] The second bonding material 362 can dry and harden into a solid state. The second bonding material 362 can fill the opening of the heater pin 30 and seal the area around the opening of the heater pin 30. The second bonding material 362 can adhere to the inner surface of the heater pin 30 around the opening of the heater pin 30.

[0063] The first bonding material 361 can be selected considering the manufacturing efficiency, manufacturing tolerances, and thermal permeability of the heating assembly, while the material for the second bonding material 362 can be selected considering the manufacturing efficiency and moisture resistance of the heating assembly. This is merely an example, and the considerations are not limited to this. The properties of the first bonding material 361 and the second bonding material 362 will be described below.

[0064] The first bonding material 361 can be formed from a low-viscosity material. The viscosity of the first bonding material 361 may be lower than that of the second bonding material 362 in its liquid state. Thus, the first bonding material 361 can be easily injected into the hollow 34, the heater 33 and support bar 332 can be easily inserted into the first bonding material 361, and the heater 33 and support bar 332 can be positioned more precisely relative to the heater pin 30.

[0065] The first bonding material 361 may have high thermal conductivity, while the second bonding material 362 may have low thermal conductivity. Therefore, the heat generated from the heater 33 can efficiently heat the stick 400 inserted into the insertion space 24 by passing through the first bonding material 361 and the heater pin 30. In addition, the heat generated from the heater 33 is insulated by the second bonding material 362, which reduces the impact of heat on other components located below the heater pin 30.

[0066] The second bonding material 362 may have greater viscosity and adhesive strength than the first bonding material 361 when in a liquid state. Therefore, the second bonding material 362 can dry and solidify in a shorter time than the first bonding material 361. Furthermore, the bonding strength of the second bonding material 362 to the inner surface of the heater pin 30 is greater than that of the first bonding material 361, and therefore, the second bonding material 362 can more effectively prevent liquids or moisture in the air from penetrating into the inside of the heater pin 30.

[0067] The second bonding material 362 may have at least one of the following properties greater than that of the first bonding material 361: moisture resistance and waterproof rating. Moisture resistance can be measured by changes in physical properties after a predetermined period of time under specific temperature and humidity conditions. Waterproof rating can be expressed as a waterproof rating. Waterproof rating is the depth to which the material can withstand the water pressure it receives in water, and can be expressed in millimeters. Therefore, even if the aerosol generator is exposed to moisture in the air for a long time, the amount of moisture absorbed by the second bonding material 362 is small, thus preventing moisture from penetrating into the heater pin 30 or reducing the amount of moisture that penetrates. The second bonding material 362 may have greater water repellency than the first bonding material 361. In addition, it is possible to prevent failure or malfunction of the heater 33 due to moisture, and to more accurately sense and control the temperature of the heater 33.

[0068] The first bonding material 361 and the second bonding material 362 may have high heat resistance. The first bonding material 361 and the second bonding material 362 may also have a small coefficient of thermal expansion. The heater pin 30, the first bonding material 361 and the second bonding material 362 may be made of a material that does not deform at the maximum temperature of the heater 33 when the heater 33 is generating heat.

[0069] Referring to Figure 12, the heater pin 30 may further include a recess 353. The recess 353 can be described as an outward recess 353. The recess 353 may be formed around the opening of the heater pin 30 by the inner surface of the heater pin 30 retracting outward from the hollow 34 with respect to the lateral direction. The recess 353 may be formed by the inner surface of the heater pin 30 retracting radially outward. The recess 353 may extend in the circumferential direction. The cross-sectional shape of the recess 353 may be circular, but is not limited to this. With respect to the cross-section, the perimeter of the recess 353 may be larger than the perimeter of the hollow 34.

[0070] The second bonding material 362 may include a central part 362a and a protruding part 362b. The second bonding material 362 in a liquid state can dry to form a central part 362a aligned with the hollow 34 in a solid state. The central part 362a may be cylindrical in shape. The second bonding material 362 in a liquid state can be injected into the recess 353 to fill it. The second bonding material 362 in a liquid state injected into the recess 353 can dry to change into a solid state. The solid state of the second bonding material 362 that has filled the recess 353 may be defined as a protruding part 362b. The protruding part 362b may project laterally from the central part 362a. The protruding part 362b may project radially outward from the central part 362a. The central part 362a may project vertically more than the protruding part 362b. The central part 362a and the protruding part 362b can be bonded to the inner surface of the heater pin 30.

[0071] Therefore, the protruding portion 362b provides a step in the gap between the central part 362a and the inner surface of the heater pin 30, thereby preventing liquid from flowing into the gap between the second bonding material 362 and the inner surface of the heater pin 30.

[0072] Referring to Figure 13, the method for manufacturing the aerosol generator may include the step (S1) of injecting the first bonding material 361 into the heater pin 30. Here, with the hollow 34 and opening of the heater pin 30 facing upwards, the first nozzle 511 of the first injector 51 can be inserted into the hollow 34 to inject the first bonding material 361 (see Figure 7). Here, the first bonding material 361 may be in a liquid state.

[0073] A method for manufacturing an aerosol generator may include the step (S2) of inserting a heater 33 into the internal hollow 34 of the heater pin 30. In the step of inserting the heater 33 (S2), the heater 33 can be inserted into the hollow 34 and the first bonding material 361 so as to be immersed in the first bonding material 361 when the first bonding material 361 is in a liquid state. Alternatively, the first bonding material 361 in liquid form can be injected into the hollow 34 with the heater 33 inserted into it. Here, the heater 33 can be inserted into the hollow 34 together with the support bar 332. Since the heater 33 is wrapped around the support bar 332, the shape of the heater 33 can be stably maintained and accurately positioned while it is inserted into the first bonding material 361 in liquid form.

[0074] A method for manufacturing an aerosol generator may include a step (S3) of drying the first bonding material 361 in a liquid state. Here, the first bonding material 361 in a liquid state is dried to a solid state and fixed to the heater pin 30, and the internal heater 33 and support bar 332 can be fixed to the heater pin 30.

[0075] The method for manufacturing the aerosol generating device may include the step (S4) of injecting a second bonding material 362 into the heater pin 30. In the step of injecting the second bonding material 362 (S4), with the heater pin 30 covered so that the hollow 34 and opening face upward, the first nozzle 511 of the first injector 51 is inserted into the hollow 34, and the second bonding material 362 can be injected into the hollow 34 adjacent to the opening on the first bonding material 361 (see Figures 9 to 11). Here, the second bonding material 362 may be in a liquid state. Here, the heater pin 30 may further include the recessed portion 353 described above, and the second bonding material 362 can flow into the recessed portion 353. Here, the lead wire 331 can pass through the second bonding material 362 and extend to the outside of the heater pin 30.

[0076] The method for manufacturing the aerosol generator may include a step (S5) of drying the liquid second bonding material 362.
