[0005] Technical issues The heat generated by the heater can heat the aerosol-generating article and can also be transferred to the outside of the aerosol-generating device. If the aerosol-generating device has weak insulation, the heat generated by the heater can easily escape to the outside. In this case, the electrical charge applied to the heater inevitably increases in order to continuously heat the aerosol-generating article at a preset temperature, thus potentially increasing the operating cost of the heater. Furthermore, the temperature rise that can be sensed when a user holds the aerosol-generating device makes it difficult to achieve a safe operating environment for the device.

[0006] Therefore, in order to reduce the operating cost of the heater and ensure the safe use of the aerosol generating device, an aerosol generating device with improved thermal insulation properties may be required.

[0041] Figure 1 This is a diagram showing an example of an aerosol-generating article being inserted into an aerosol-generating apparatus.

[0042] refer to Figure 1 The aerosol generating device 100 may include a battery 110, a controller 120, and a heater assembly 1.

[0043] The aerosol generating apparatus 100 may also include a vaporizer 130. Furthermore, the aerosol generating article 200 may be inserted into the internal space of the aerosol generating apparatus 100.

[0044] Figure 1 Components of the aerosol generating apparatus 100 relevant to this embodiment are shown. Therefore, those skilled in the art who are familiar with this embodiment will understand that, in addition to… Figure 1 In addition to the components shown, the aerosol generating apparatus 100 may also include additional components.

[0045] Figure 1 The battery 110, controller 120, vaporizer 130, and heater assembly 1 are shown arranged in series. However, the internal structure of the aerosol generating device 100 is not limited to... Figure 1 The arrangement is shown. In other words, depending on the design of the aerosol generating device 100, the battery 110, controller 120, vaporizer 130, and heater assembly 1 can be arranged differently.

[0046] When the aerosol generating article 200 is inserted into the aerosol generating apparatus 100, the aerosol generating apparatus 100 heats the heater assembly 1 and / or the vaporizer 130 to generate aerosol from the aerosol generating article 200 and the vaporizer 130. The aerosol generated from the heater assembly 1 and / or the vaporizer 130 can be delivered to the user through the aerosol generating article 200.

[0047] As needed, the aerosol generating apparatus 100 can heat the heater assembly 1 even when the aerosol generating article 200 is not inserted into the aerosol generating apparatus 100.

[0048] Battery 110 can supply power for the operation of aerosol generating apparatus 100. For example, battery 110 can supply power to heat heater assembly 1 or vaporizer 130, and can supply power for operating controller 120. In addition, battery 110 can supply power for the operation of displays, sensors, motors, etc. installed in aerosol generating apparatus 100.

[0049] The controller 120 typically controls the operation of the aerosol generating apparatus 100. Specifically, the controller 120 controls not only the operation of the battery 110, heater assembly 1, and vaporizer 130, but also the operation of other components included in the aerosol generating apparatus 100. Furthermore, the controller 120 can check the status of each component of the aerosol generating apparatus 100 to determine whether the aerosol generating apparatus 100 is operational.

[0050] The controller 120 may include at least one processor. The processor may be implemented as an array of logic gates, or as a combination of a general-purpose microprocessor and a memory storing a program executable by the microprocessor. Those skilled in the art will understand that the processor may be implemented in other forms of hardware.

[0051] The heater assembly 1 can be heated by electricity supplied from the battery 110. For example, when the aerosol generating article 200 is inserted into the aerosol generating apparatus 100, the heater assembly 1 can be located outside the aerosol generating article 200. Therefore, the heated heater assembly 1 can increase the temperature of the aerosol generating substance in the aerosol generating article 200.

[0052] Heater assembly 1 may include a resistance heater. For example, heater assembly 1 may include a conductive rail, and heater assembly 1 may be heated when current flows through the conductive rail. However, heater assembly 1 is not limited to the above example and may include any other heater that can be heated to a desired temperature. Here, the desired temperature may be preset in the aerosol generating device 100 or may be set by the user.

[0053] As another example, heater assembly 1 may include an induction heater. Specifically, heater assembly 1 may include a conductive coil for heating the aerosol-generating article by induction heating, and the aerosol-generating article may include a base that can be heated by the induction heater. Heater 10 may be a conductive coil.

[0054] Although the embodiment describes heater assembly 1 as an induction heater, the embodiment is not limited to the type of heater. For example, heater assembly 1 can be implemented as a resistance heater.

[0055] For example, heater assembly 1 may include tubular heating elements, plate heating elements, needle heating elements or rod heating elements, and may heat the interior or exterior of aerosol generating article 200 depending on the shape of the heating element.

[0056] Furthermore, the aerosol generating apparatus 100 may include a plurality of heaters. These heaters may be inserted into the aerosol generating article 200 or disposed outside the aerosol generating article 200. Moreover, some of the heater assemblies 1 may be inserted into the aerosol generating article 200, while others may be disposed outside the aerosol generating article 200.

[0057] In addition, the shape of heater assembly 1 is not limited to Figure 1 The shape shown can be, and can include various shapes.

[0058] The vaporizer 130 can generate an aerosol by heating the liquid composition, and the generated aerosol can be delivered to the user through the aerosol generating article 200. In other words, the aerosol generated by the vaporizer 130 can move along the airflow channel of the aerosol generating device 100, and the airflow channel can be configured such that the aerosol generated by the vaporizer 130 can be delivered to the user through the aerosol generating article 200.

[0059] For example, the vaporizer 130 may include a liquid storage unit, a liquid transfer element, and a heating element, but is not limited thereto. For example, the liquid storage unit, the liquid transfer element, and the heating element may be included as separate modules in the aerosol generating apparatus 100.

[0060] The liquid storage section can store a liquid composition. For example, the liquid composition can be a liquid containing tobacco material having volatile tobacco flavor components, or a liquid containing non-tobacco material. The liquid storage section can be detachable from the vaporizer 130, or it can be integrally formed with the vaporizer 130.

[0061] For example, the liquid composition may include water, solvent, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. Fragrances may include, but are not limited to, menthol, peppermint oil, spearmint oil, and various fruit flavoring ingredients. Flavorings may include ingredients capable of providing a variety of fragrances or tastes to the user. Vitamin mixtures may be, but are not limited to, a mixture of at least one of vitamins A, B, C, and E. Furthermore, the liquid composition may include aerosol-forming substances such as glycerin and propylene glycol.

[0062] A liquid delivery element can deliver a liquid composition from a liquid reservoir to a heating element. For example, the liquid delivery element can be a core, such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited thereto.

[0063] A heating element is a component used to heat a liquid composition conveyed by a liquid conveying element. For example, a heating element can be a metal heating wire, a metal hot plate, a ceramic heater, etc., but is not limited to these. Furthermore, the heating element may include conductive wire, such as nichrome wire, and may be positioned to be wound around the liquid conveying element. The heating element can be heated by a power source and can transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol can be generated.

[0064] For example, vaporizer 130 can be called a cartridge or atomizer, but is not limited to that.

[0065] In addition to the battery 110, controller 120, heater assembly 1, and vaporizer 130, the aerosol generating apparatus 100 may also include general-purpose components. For example, the aerosol generating apparatus 100 may include a display capable of outputting visual information and / or a motor for outputting tactile information. Furthermore, the aerosol generating apparatus 100 may include at least one sensor (suction sensor, temperature sensor, aerosol generating article insertion detection sensor, etc.). Moreover, the aerosol generating apparatus 100 may be configured to allow the introduction of external air or the exhaust of internal air even when the aerosol generating article 200 is inserted into the aerosol generating apparatus 100.

[0066] Despite Figure 1 Not shown, but the aerosol generating device 100 and the additional bracket can form a system together. For example, the bracket can be used to charge the battery 110 of the aerosol generating device 100. Alternatively, the heater assembly 1 can be heated when the bracket and the aerosol generating device 100 are connected to each other.

[0067] The aerosol-generating article 200 can be similar to a regular cigarette. For example, the aerosol-generating article 200 can be divided into a first part including an aerosol-generating substance and a second part including a filter. Alternatively, the second part of the aerosol-generating article 200 can also include the aerosol-generating substance. For example, the aerosol-generating substance, in the form of granules or capsules, can be inserted into the second part.

[0068] The first part can be fully inserted into the aerosol generating device 100, while the second part can be exposed to the outside. Alternatively, only a portion of the first part can be inserted into the aerosol generating device 100, or a portion of both the first and second parts can be inserted into the aerosol generating device. The user can inhale the aerosol while holding the second part in their mouth. In this case, the aerosol is generated by external air passing through the first part, and the generated aerosol passes through the second part and is delivered to the user's mouth.

[0069] For example, outside air can flow into at least one air passage formed in the aerosol generating device 100. For example, the opening and closing of the air passage formed in the aerosol generating device 100 and / or the size of the air passage can be adjusted by the user. Therefore, the amount and quality of smoke can be adjusted by the user. As another example, outside air can flow into the aerosol generating article 200 through at least one hole formed in the surface of the aerosol generating article 200.

[0070] Figure 2 This is a front perspective view of a heater assembly for an aerosol generating apparatus according to an embodiment, and Figure 3 This is a rear perspective view of a heater assembly for an aerosol generating apparatus according to an embodiment.

[0071] refer to Figure 2 and Figure 3 According to an embodiment, the heater assembly 1 for an aerosol generating apparatus may include a body 2, a first cover 3, and a second cover 4. However, according to an embodiment, the components of the heater assembly 1 for the aerosol generating apparatus 1 are not limited to this; other components may be added, or at least one component may be omitted.

[0072] The first cover 3 can be attached to one side of the body 2. The retainer 20 for supporting the aerosol-generating article 200 can be attached to the first cover 3.

[0073] The second cover 4 can be connected to the other side of the body 2. That is, the first cover 3 and the second cover 4 can be connected to different parts of the body 2 respectively.

[0074] The second cover 4 may include a second cover body 41, a second protruding member 42, a second hole 43, and a sealing member insertion groove 44.

[0075] The second cover body 41 can be used as the body of the second cover 4. The second cover body 41 can be connected to the body 2 to be arranged on the other side of the body 2. The second cover body 41 can be generally formed in the shape of a circular plate, but this is only an example and it can be formed in other shapes, as long as the second cover body 41 can be arranged on the other side of the body 2.

[0076] The second protruding member 42 can protrude from the second cover body 41. The second protruding member 42 can be integrally formed with the second cover body 41. The second protruding member 42 can be generally formed in a ring shape.

[0077] The second hole 43 can be formed in the second protruding member 42 to provide Figure 8 At least one of the contact portions shown passes through, such as the heating contact portion 10a of the heater 10, the antenna contact portion 53 of the antenna 5, and the sensing contact portion 63 of the sensor 6. At least one of the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63 can penetrate the second hole 43 and can be electrically connected to the battery 110 or the controller 120. The second hole 43 can penetrate the second cover body 41 and the second protruding member 42. The second hole 43 can be formed to a larger size than each of the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63.

[0078] Lower seal 8 (see Figure 4 A portion of the seal can be inserted into the seal insertion groove 44. The seal insertion groove 44 can be formed on the outer surface of the second protruding member 42. The seal insertion groove 44 can be formed on opposite sides of the second protruding member 42.

[0079] Figure 4 This is an exploded perspective view of a heater assembly for an aerosol generating apparatus according to an embodiment.

[0080] refer to Figure 4 According to the embodiment, the heater assembly 1 for the aerosol generating apparatus may further include an antenna 5, a sensor 6, a shielding portion 7, a lower seal 8, a support 9, a heater 10, a base 11, and a retainer 20. However, according to the embodiment, the components of the heater assembly 1 for the aerosol generating apparatus 1 are not limited to these; other components may be added, or at least one component may be omitted.

[0081] Figure 5 The heater assembly for an aerosol generating apparatus according to an embodiment is along... Figure 2The cross-sectional view of line VV shown; and Figure 6 The heater assembly for an aerosol generating apparatus according to an embodiment is along... Figure 2 The cross-sectional view shown is taken from line VI-VI.

[0082] refer to Figure 5 and Figure 6 According to an embodiment, a heater assembly 1 for an aerosol generating apparatus includes: a heater 10 (e.g., a conductive coil) configured to heat an aerosol generating article 200; a body 2 arranged around the aerosol generating article 200; a first cover 3 disposed on one side of the body 2 and including a first hole 311 through which the aerosol generating article 200 is inserted; and a second cover 4 including a second hole 43 (see...). Figure 3 , Figure 12 and Figure 13 The line used to supply power to the heater 10 penetrates through the second hole 43 to the outside of the heater assembly 1.

[0083] The first cover 3 is connected to one side of the body 2, and the second cover 4 is connected to the other side of the body 2, thereby forming a accommodating space 21 for accommodating the aerosol-generated article.

[0084] At least a portion of the inner surface of at least one of the body 2, the first cover 3, and the second cover 4 is deposited with a material that reflects the heat generated by the heater 10 to the accommodating space 21. Therefore, the heater assembly 1 for the aerosol generating apparatus according to the embodiment can achieve the following beneficial effects.

[0085] First, the heater assembly 1, second cover 4, first cover 3, and body 2 of the aerosol generating apparatus according to the embodiment can be arranged to completely surround the exterior of the heater 10 and serve as a physical barrier, which is configured to prevent heat generated from the heater 10 from being released to the outside. Therefore, the heater assembly 1 of the aerosol generating apparatus according to the embodiment can improve insulation performance through the physical barrier, and thus reduce the power consumption of the heater 10 during operation.

[0086] Secondly, the heater assembly 1 for the aerosol generating apparatus according to the embodiment can reduce the heat transferred to the aerosol generating apparatus 100, thereby reducing the temperature felt by the user when holding the aerosol generating apparatus 100. Therefore, the heater assembly 1 for the aerosol generating apparatus according to the embodiment can provide a safe operating environment for the use of the aerosol generating apparatus 100.

[0087] Third, the deposited material can reflect the heat generated from the heater 10 back to the accommodating space 21, thereby reducing the heat transferred to the outside. Therefore, the heater assembly 1 of the aerosol generating apparatus according to the embodiment can have improved insulation performance.

[0088] The three beneficial effects mentioned above can be demonstrated by the following experiments.

[0089] [experiment] First, the temperature distribution of the heater assembly 1 for the aerosol generating apparatus according to the embodiment is set such that the base 11 is heated to 270°C (process 1).

[0090] Next, heat base 11 for 270 seconds (process 2).

[0091] Next, repeat process 1 and process 2 three times (process 3).

[0092] Five minutes later, the temperature of the aerosol generating device 100 was measured (process 4).

[0093] Next, processes 1 to 4 (process 5) are repeated using a heater assembly according to the relevant technology (comparative example 1) and a heater assembly including a vacuum tube insulation structure (comparative example 2).

[0094] Table 1 below shows the experimental results. [Table 1]

[0095] As shown in Table 1 above, due to the heater assembly 1 for the aerosol generating apparatus according to the embodiment, the temperature of the aerosol generating apparatus 100 is approximately 27°C lower than the temperature in Comparative Example 1. Based on this, the overall insulation performance of the heater assembly 1 for the aerosol generating apparatus according to the embodiment is improved compared to related technologies. Furthermore, it was found that the heater assembly 1 for the aerosol generating apparatus according to the embodiment has similar insulation performance to Comparative Example 2, which includes an insulation structure with a vacuum tube. The body 2, the first cover 3, and the second cover 4 will now be described in detail with reference to the accompanying drawings.

[0096] Terms such as “upper” or “lower” used in the specification are intended to distinguish the position of components in the lower part of the heater assembly 1 of the aerosol generating apparatus according to the embodiment, and are not intended to indicate a particular direction.

[0097] refer to Figure 5 and Figure 6 The body component 2 is arranged outside the heater 10 to surround the heater 10. The body component 2 can prevent the heat generated from the heater 10 from being discharged to the outside.

[0098] A receiving space 21 for accommodating the aerosol generating article 200 is formed in the body 2. When the aerosol generating article 200 is accommodated in the receiving space 21, the aerosol generating article 200 can be arranged inside the base 11. When the heating contact portion 10a of the heater is electrically connected to the battery 110 and the heater 10 heats the base 11 using power supplied from the battery 110, the aerosol generating article 200 can be heated by induction heating and can generate aerosol. As described above, the heating contact portion 10a may include power lines to supply power to the heater 10. Although Figure 7 The base 11 shown is formed in a hollow cylindrical shape, which is merely an example. That is, the base 11 can also be formed in other shapes as long as it can accommodate the aerosol generating article 200. The base 11 can be arranged inside the heater 10. The base 11 can include a metallic material.

[0099] Material capable of reflecting heat generated by heater 10 to receiving space 21 can be deposited on the inner surface of body 2. The inner surface of body 2 can be the surface of body 2 facing heater 10. The material can include metallic materials, such as silver (Ag).

[0100] Although the body component 2 can be generally formed into a hollow cylindrical shape, this is only an example. That is, the body component 2 can also be formed into other shapes as long as it can accommodate the heater 10. The body component 2 can include a metallic material. For example, the body component 2 can include a material such as stainless steel (SUS) or aluminum.

[0101] refer to Figure 5 and Figure 6 A first cover 3 is disposed on one side of the body 2 to cover one side of the heater 10. The first cover 3 prevents heat generated from the heater 10 from escaping from the heater assembly 1 through one side of the body 2. This side of the body 2 may include the top portion of the body 2.

[0102] The first cover 3 and the body 2 can be connected to each other to form a receiving space 21 for containing the aerosol-generating article 200.

[0103] Material capable of reflecting heat generated from heater 10 to accommodating space 21 can be deposited on the inner surface of first cover 3. The inner surface of first cover 3 can be the surface of first cover 3 facing heater 10.

[0104] The first cover 3 may include a polymer material with high heat resistance. For example, the first cover 3 may include materials such as polyetheretherketone (PEEK), polyphenylene sulfone (PPSU), and polycarbonate (PC).

[0105] refer toFigure 5 and Figure 6 The first cover 3 may include the first cover body 31.

[0106] The first cover body 31 can serve as the body of the first cover 3. The first cover body 31 can be attached to the body 2 to be disposed on one side of the body 2. When the first cover body 31 is attached to the body 2, the first cover body 31 can cover one side of the heater 10. The first cover body 31 can be generally formed in a circular shape, but the implementation is not limited to this. That is, the first cover body 31 can be formed in other shapes, as long as the first cover body 31 can be disposed on one side of the body 2 to cover the heater 10.

[0107] The first cover 3 may also include a first hole 311. The aerosol generating article 200 may be inserted into the first hole 311. The first hole 311 may be formed in the first cover body 31 to penetrate the top and bottom portions of the first cover body 31.

[0108] refer to Figure 5 The first cover 3 may further include a retainer insertion slot 312. A retainer 20 can be inserted into the retainer insertion slot 312. When the retainer 20 is inserted into the retainer insertion slot 312, the retainer 20 is connected to the first cover 3. The retainer insertion slot 312 may be formed on the upper surface of the first cover body 31.

[0109] refer to Figure 6 The first cover 3 may further include a first body insertion slot 313. A side portion of the body 2 can be inserted into the first body insertion slot 313. When this side portion of the body 2 is inserted into the first body insertion slot 313, the body 2 can be connected to the first cover 3. Therefore, the first cover 3 can support this side portion of the body 2. The first body insertion slot 313 may be formed in the lower surface of the first cover body 31.

[0110] refer to Figure 5 and Figure 6 The first cover 3 may also include a cover insulation member 32.

[0111] The cover insulating member 32 extends along the longitudinal direction of the heater 10. The cover insulating member 32 can be arranged between the heater 10 and the body member 2. Therefore, the heater assembly 1 for the aerosol generating apparatus according to the embodiment can achieve a double-layer physical barrier through the cover insulating member 32 and the body member 2, which prevents heat generated from the heater 10 from being emitted to the outside. The longitudinal direction of the heater 10 can represent the direction of extension of the long side of the heater assembly 1 for the aerosol generating apparatus according to the embodiment.

[0112] The cover insulation member 32 can extend in the longitudinal direction to a length greater than that of the heater 10. Therefore, the area that the cover insulation member 32 can cover the heater 10 can be increased.

[0113] The cover insulating member 32 can be connected to the first cover body 31 and can extend along the longitudinal direction of the heater 10. The cover insulating member 32 can be integrally formed with the first cover body 31.

[0114] When the first cover 3 is attached to the body 2, the cover insulation member 32 can be inserted into the body 2 to surround a portion of the exterior of the heater 10. That is, the side surface of the cover insulation member 32 may include an opening such that the heater 10 is partially surrounded by the cover insulation member 32.

[0115] Therefore, compared to the comparative example where the cover insulation member 32 completely surrounds the outside of the heater 10, in the heater assembly 1 for the aerosol generating apparatus, the cover insulation member 32 can be easily inserted into the body member 2. In this embodiment, during the insertion of the cover insulation member 32 into the body member 2, less interference occurs between the cover insulation member 32 and the body member 2 compared to the comparative example. Therefore, in the heater assembly 1 for the aerosol generating apparatus according to the embodiment, the assembly of the first cover member 3 and the body member 2 can be easy.

[0116] refer to Figure 6 The first cover 3 may also include a first protruding member 33.

[0117] The first protruding member 33 may protrude outward from the first cover body 31. The first protruding member 33 may be arranged at both ends of the first cover body 31. The first protruding member 33, the cover insulating member 32, and the first cover body 31 may be integrally formed.

[0118] The first protruding member 33 may include a connecting hole 331. A connecting member 3a (such as...) is used to connect the first cover 3 to the aerosol generating device 100. Figure 7 (As shown) can be inserted into the connecting hole 331. When the connecting member 3a is inserted into the connecting hole 331 and connected to the aerosol generating device 100, the first cover 3 can be fixed to the aerosol generating device 100. The connecting member 3a can be a bolt. In this case, threads can be formed in the connecting hole 331.

[0119] refer to Figure 5 and Figure 6A second cover 4 is disposed on the other side of the body 2 to cover the other side of the heater 10. The second cover 4 can prevent heat generated from the heater 10 from being discharged to the outside through the other side of the body 2. The other side of the body 2 can be the bottom portion of the body 2.

[0120] The second cover 4 and the other side of the main body 2 can be connected to each other to form an accommodating space 21. That is, the main body 2, the first cover 3 and the second cover 4 can be arranged to be connected to each other and completely surround the accommodating space 21.

[0121] Material capable of reflecting heat generated from heater 10 to accommodating space 21 can be deposited on the inner surface of second cover 4. The inner surface of second cover 4 can be the surface of second cover 4 facing heater 10.

[0122] The second cover 4 may include a polymer material with high heat resistance. For example, the second cover 4 may include materials such as PEEK, PPSU, and PC.

[0123] refer to Figure 5 and Figure 6 The second cover 4 may also include a second body insertion slot 411.

[0124] The other side of the main body 2 can be inserted into the second main body insertion slot 411. When the other side of the main body 2 is inserted into the second main body insertion slot 411, the main body 2 can be connected to the second cover 4. Therefore, the second cover 4 can support the other side of the main body 2. The second main body insertion slot 411 can be formed in the second cover body 41.

[0125] refer to Figure 5 and Figure 6 The second cover 4 may also include a joining member 412.

[0126] The engaging member 412 can be inserted into the cover insertion slot 22 formed in the body member 2. When the engaging member 412 is inserted into the cover insertion slot 22, the other side of the body member 2 can be connected to the second cover member 4. Therefore, the second cover member 4 and the body member 2 can be securely connected to each other. The engaging member 412 can protrude from the second cover member body 41 toward the second body insertion slot 411. The engaging member 412 can be integrally formed with the second cover member body 41.

[0127] refer to Figure 5 and Figure 6 The antenna 5 identifies whether the aerosol-generating article 200 is contained within the containing space 21. The antenna 5 can be connected to the battery 110 and the controller 120. The antenna 5 may include a metallic material.

[0128] For example, when the aerosol generating article 200 is contained in the containing space 21, the antenna 5 can identify the aerosol generating article 200 contained in the containing space 21 and provide the controller 120 with information related to the containing state of the aerosol generating article 200. Therefore, the controller 120 can control the battery 110 to provide power to the heater 10.

[0129] As another example, when the aerosol generating article 200 separates from the containing space 21, the antenna 5 can identify the separating aerosol generating article 200 and provide the controller 120 with information related to the separation state of the aerosol generating article 200. Therefore, the controller 120 can control the battery 110 to prevent the supply of power to the heater 10.

[0130] Antenna 5 is disposed inside body 2. Antenna 5 may be disposed between cover insulating member 32 and shielding portion 7 to surround at least a portion of heater 10. Thus, heater assembly 1 for aerosol generating apparatus according to embodiment can achieve a three-layer physical barrier through cover insulating member 32, antenna 5 and body 2, which prevents heat generated from heater 10 from being discharged to the outside.

[0131] refer to Figure 5 and Figure 6 Sensor 6 senses the temperature of heater 10 and / or base 11. For example... Figure 5 As shown, sensor 6 can contact base 11. Sensor 6 can be connected to battery 110 or controller 120.

[0132] The sensor 6 may be disposed inside the body 2, and at least a portion of the sensor 6 may extend along the longitudinal direction of the heater 10. The sensor 6 may include a metallic material.

[0133] refer to Figure 5 The sensor 6 may include a sensing body 61 and a bending member 62.

[0134] At least a portion of the sensing body 61 extends along the longitudinal direction of the heater 10. The sensing body 61 may be arranged between the body 2 and the shielding portion 7.

[0135] The bending member 62 extends toward the base 11, causing the sensor 6 to contact the base 11. The bending member 62 may pass between the cover body 3 and the support member 9 and extend toward the base 11. The bending member 62 may be connected to the upper portion of the sensing body 61.

[0136] refer to Figure 5 and Figure 6The shielding portion 7 is arranged inside the body component 2. The shielding portion 7 is arranged between the body component 2 and the antenna 5 to surround at least a portion of the heater 10. Therefore, the heater assembly 1 for the aerosol generating apparatus according to the embodiment can achieve the following beneficial effects.

[0137] First, in the heater assembly 1 for the aerosol generating apparatus according to the embodiment, the shielding portion 7 is arranged outside the antenna 5, thus reducing the likelihood that the antenna 5 will identify electronic devices located outside the shielding portion 7. Therefore, in the heater assembly 1 for the aerosol generating apparatus according to the embodiment, since the antenna 5 can identify only whether the aerosol generating article 200 is contained, the performance of the antenna 5 can be improved.

[0138] Secondly, the heater assembly 1 for the aerosol generating apparatus according to the embodiment can achieve four layers of physical barriers through the cover insulating member 32, the antenna 5, the shielding portion 7, and the body member 2, which prevents heat generated from the heater 10 from being emitted to the outside. Therefore, the heater assembly 1 for the aerosol generating apparatus according to the embodiment can have improved insulation performance.

[0139] The shielding portion 7 may include a metallic material. For example, the shielding portion 7 may include materials such as aluminum (Al) and silver (Ag).

[0140] refer to Figure 5 and Figure 6 The lower seal 8 can seal the gap between the second cover 4 and at least one of the contact portions 10a, 53 and 63 (see [link]). Figure 8 The lower seal 8 can be connected to the second cover 4. The lower seal 8 can be connected to the exterior of the second protruding member 42 and the interior of the second protruding member 42. The lower seal 8 may include rubber. The lower seal 8 may include a first seal 81 and a second seal 82, the details of which will be described later.

[0141] refer to Figure 5 and Figure 6 The support member 9 is arranged inside the heater 10 and supports the heater 10. The heater 10 can be connected to the support member 9. Although the support member 9 can be generally formed into a hollow cylindrical shape, this is only an example. That is, the support member 9 can be formed into other shapes as long as it can support the heater 10.

[0142] The base 11 can be arranged inside the support 9. Therefore, the support 9 can prevent the heat generated from the base 11 from being discharged to the outside.

[0143] refer to Figure 4 to Figure 6The heater assembly 1 for the aerosol generating apparatus according to the embodiment may further include a first sealing ring 30, a second sealing ring 40 and a third sealing ring 50.

[0144] The first sealing ring 30 can be arranged between the retainer 20 and the first cover 3. The first sealing ring 30 can seal the gap between the retainer 20 and the first cover 3.

[0145] The second sealing ring 40 may be disposed within the first cover 3. The second sealing ring 40 may be disposed inside the first cover body 31 to surround the first hole 311. At least a portion of the aerosol generating article 200 may be inserted into the second sealing ring 40. When the aerosol generating article 200 is accommodated in the accommodating space 21, the second sealing ring 40 may seal the gap between the aerosol generating article 200 and the first cover body 31.

[0146] The third sealing ring 50 may be disposed at the bottom end of the base 11, within the support member 9. At least a portion of the aerosol generating article 200 may be inserted into the third sealing ring 50. When the aerosol generating article 200 is housed in the receiving space 21, the third sealing ring 50 may seal the gap between the aerosol generating article 200 and the support member 9.

[0147] The first sealing ring 30, the second sealing ring 40, and the third sealing ring 50 may all comprise rubber. The first sealing ring 30, the second sealing ring 40, and the third sealing ring 50 may all be formed in a circular shape, but their shapes are not limited.

[0148] Figure 7 This is a perspective view of the combination of a first cover, a heater, and a retainer in a heater assembly for an aerosol generating apparatus according to an embodiment.

[0149] The retainer 20 supports the aerosol-generating article 200. The retainer 20 may include: an insertion hole 20a through which the aerosol-generating article 200 is inserted; a ridge 20b protruding toward the insertion hole 20a and supporting the aerosol-generating article 200; and a retainer protrusion 20c protruding toward the first cover body 31 and to be inserted into a retainer insertion slot 312. When the retainer protrusion 20c is inserted into the retainer insertion slot 312, the retainer 20 can be connected to the first cover body 31.

[0150] When the retainer 20 is connected to the first cover body 31, the insertion hole 20a of the retainer 20 can communicate with the first hole 311 of the first cover body 31.

[0151] The retainer 20 may include a plurality of ridges 20b. The plurality of ridges 20b may be arranged spaced apart from each other in the circumferential direction of the retainer 20.

[0152] Figure 8 This is a cross-sectional view of the combination of the heater, antenna, and sensor in the heater assembly of an aerosol generating apparatus according to an embodiment; and Figure 9 This is a cross-sectional view of the combination of the cover and the antenna in the heater assembly of the aerosol generating apparatus according to an embodiment.

[0153] refer to Figure 8 and Figure 9 The antenna 5 may include an antenna body 51, an antenna extension portion 52, and an antenna contact portion 53.

[0154] like Figure 8 As shown, the antenna body 51 extends along the longitudinal direction of the heater 10 and is arranged to surround a portion of the heater 10. That is, the side surface of the antenna body 51 may include an opening such that the heater 10 is partially surrounded by the antenna body 51.

[0155] Therefore, compared to the comparative example where the antenna body 51 completely surrounds the heater 10, in the heater assembly 1 for the aerosol generating apparatus according to the embodiment, the antenna body 51 can be easily inserted into the body member 2. In the embodiment, during the insertion of the antenna body 51 into the body member 2, less interference occurs between the antenna cover 51 and the body member 2 compared to the comparative example. Therefore, the heater assembly 1 for the aerosol generating apparatus according to the embodiment facilitates the assembly of the antenna 5 and the body member 2.

[0156] When the antenna body 51 extends along the longitudinal direction of the heater 10 and is arranged to surround a portion of the heater 10, the covering insulating member 32 can be arranged at a position corresponding to the position of the antenna body 51, such as... Figure 9 As shown. Therefore, the antenna body 51 can support the cover insulating member 32 at the outside of the cover insulating member 32.

[0157] Antenna extension 52 is connected to antenna body 51. Antenna extension 52 may include a first extension and a second extension, the first extension extending from one side of antenna body 51 along the circumferential direction of heater 10, and the second extension extending from the other side of antenna body 51 along the circumferential direction of heater 10.

[0158] refer to Figure 8The antenna 5 may include a penetrating portion 5a through which the bending member 62 of the sensor 6 passes. Therefore, in the heater assembly 1 for the aerosol generating apparatus according to the embodiment, the sensor 6 may not be electrically connected to the antenna 5 when in contact with the base 11 located inside the heater 10. Thus, the heater assembly 1 for the aerosol generating apparatus according to the embodiment can reduce the possibility of an electrical short circuit between the antenna 5 and the sensor 6. The penetrating portion 5a may be the space between a first extension and a second extension.

[0159] refer to Figure 8 and Figure 9 Antenna contact portion 53 is connected to antenna body 51 and is positioned at a distance spaced from antenna extension portion 52. Antenna contact portion 53 can be connected to battery 110 and / or controller 120. Antenna contact portion 53 may include: a first contact member extending across the longitudinal direction of heater 10; and a second contact member extending along the longitudinal direction of heater. Antenna contact portion 53, antenna extension portion 52, and antenna body 51 may be integrally formed.

[0160] Figure 10 This is a perspective view of the combination of the antenna, sensor, and shielding portion of the heater assembly for an aerosol generating apparatus according to an embodiment.

[0161] refer to Figure 10 The sensor 6 may include a sensing body 61, a bending member 62, and a sensing contact portion 63. References will be omitted below. Figure 5 The description of the sensing body 61 and the bending member 62 is repeated.

[0162] The sensing body 61 may include a first body extending along the longitudinal direction of the heater 10, a second body connected to the first body and extending across the longitudinal direction, and a third body connected to the second body and the sensing contact portion 63.

[0163] The bending member 62 may include a first bending member extending across the longitudinal direction and a second bending member connected to the first bending member and bending downward toward the base 11.

[0164] The sensing contact portion 63 can be connected to the bottom of the sensing body 61. The sensing contact portion 63 can be connected to the battery 110 and / or the controller 120. The sensing contact portion 63 may include two contact members extending in different directions. The sensing contact portion 63, the bending member 62, and the sensing body 61 can be integrally formed.

[0165] refer to Figure 10 The shielding part 7 may include a shielding body 71 and a sensor penetration groove 72.

[0166] The shielding body 71 can form the overall appearance of the shielding portion 7. The shielding body 71 can be arranged inside the body component 2 to surround the antenna 5. The shielding body 71 can be formed as a hollow cylindrical shape, but this is only an example. That is to say, the shielding body 71 can be formed into other shapes, as long as the shielding body 71 can be arranged outside the antenna 5.

[0167] The sensor penetration slot 72 can be a space through which the bending member 62 penetrates. Therefore, the heater assembly 1 for the aerosol generating apparatus according to the embodiment can have a structure in which the shielding portion 7 and the sensor 6 are not electrically connected to each other, while the sensor 6 contacts the base 11 located inside the shielding portion 7. Therefore, the heater assembly 1 for the aerosol generating apparatus according to the embodiment can reduce the possibility of an electrical short circuit between the shielding portion 7 and the sensor 6. The sensor penetration slot 72 can be formed in the shielding body 71.

[0168] Figure 11 This is a rear perspective view of a heater assembly for an aerosol generating apparatus according to an embodiment.

[0169] refer to Figure 11 The heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63 penetrate the second hole 43 (see...). Figure 3 and Figure 12 to Figure 13 The lower seal 8 can seal the gap between the second cover 4 and at least one of the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63. The lower seal 8 can be connected to the second protruding member 42.

[0170] Figure 12 This is an exploded view of the lower seal and the second cover in the heater assembly of the aerosol generating apparatus according to an embodiment, and Figure 13 A second cover for a heater assembly of an aerosol generating apparatus according to an embodiment is shown.

[0171] refer to Figure 12 The lower seal 8 may include a first seal 81 inserted into the second hole 43 and a second seal 82 arranged separately from the first seal 81.

[0172] The first seal 81 can be inserted into the second hole 43 and contact the inner surface 4a of the second protruding member 42 (e.g., Figure 13 (As shown) to seal the second hole 43. Therefore, the first seal 81 prevents heat generated from the heater 10 from escaping downwards through the second hole 43. The inner surface 4a can be the surface of the second protruding member 42 facing the second hole 43.

[0173] The first seal 81 can be inserted into the second hole 43 by an interference fit method. Therefore, the sealing force of the first seal 81 in sealing the second hole 43 can be improved.

[0174] The second seal 82 is arranged separately from the first seal 81. The second seal 82 can be connected to the outer surface 4b of the second protruding member 42 (e.g., Figure 13 (As shown). The outer surface 4b is the surface opposite to the inner surface 4a. The outer surface 4b of the second protruding member 42 may be the same surface as the outer surface of the second cover 4. The second seal 82 may be arranged around the second protruding member 42.

[0175] Figure 14 A first seal for a heater assembly of an aerosol generating apparatus according to an embodiment is shown.

[0176] refer to Figure 14 The first sealing element 81 includes a first sealing body 811, a first through groove 812, and a second through groove 813.

[0177] The first sealing body 811 is inserted into the second hole 43. The first through groove 812 and the second through groove 813 can be formed in the first sealing body 811. The first sealing body 811 can generally be formed into a rectangular shape. However, the first sealing member 811 can also be formed into other shapes as long as it can be inserted into the second hole 43.

[0178] A first penetration groove 812 can be formed in the first sealing member 811 to allow the heated contact portion 10a to penetrate. The first penetration groove 812 can be formed by processing a groove having a certain depth from the outer surface of the first sealing body 811. Although Figure 14 Two first penetration slots 812 are shown, this is just an example, and the number of first penetration slots 812 is not limited.

[0179] The second penetration groove 813 can be formed separately from the first penetration groove 812, and the sensing contact portion 63 can penetrate the second penetration groove 813. The second penetration groove 813 can be formed by processing a groove having a certain depth from the outer surface of the first sealing body 811. Although Figure 14 A second through-slot 813 is shown; this is merely an example, and the number of second through-slots 813 is not limited.

[0180] Figure 15 This is a diagram of the second seal of a heater assembly for an aerosol generating apparatus according to an embodiment.

[0181] refer to Figure 15The second seal 82 may include a second sealing body 821, a second cover insertion groove 822, and a sealing protrusion 823.

[0182] The second sealing body 821 is connected to the second protruding member 42 of the second cover 4. The second cover insertion groove 822 and the sealing protrusion 823 can be formed in the second sealing body 821. The second sealing body 821 can serve as the body of the second seal 82.

[0183] The second protruding member 42 of the second cover 4 can be inserted into the second cover insertion slot 822. For example, the second protruding member 42 can be inserted into the second cover insertion slot 822 by an interference fit method, so that no gap is formed between the second protruding member 42 and the second sealing body 821.

[0184] The sealing protrusion 823 protrudes toward the second cover insertion groove 822. When the second protruding member 42 of the second cover 4 is inserted into the second cover insertion groove 822 of the second seal 82, the sealing protrusion 823 is inserted into the sealing insertion groove 44 formed in the outer surface 4b of the second protruding member 42 (see...). Figure 12 Therefore, the second cover 4 and the second seal 82 can be securely connected to each other. The sealing protrusion 823 can be formed at different locations on the inner surface of the second sealing body 821. The sealing protrusion 823 can be integrally formed with the second sealing body 821.

[0185] Figure 16 The heater assembly for an aerosol generating apparatus according to an embodiment is along... Figure 11 The cross-sectional view shown is taken from line XVI-XVI.

[0186] When the first seal 81 is inserted into the second hole 43, as Figure 16 As shown, the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63 can be arranged between the first seal 81 and the second cover 4. Therefore, even when vibration or shaking is applied to the heater assembly 1 for the aerosol generating apparatus according to the embodiment, the movement of the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63 can be restricted.

[0187] When the first seal 81 is inserted into the second hole 43 by means of interference fit, the first seal 81 can press the heating contact portion 10a, the antenna contact portion 53 and the sensing contact portion 63 against the inner surface 42 of the second protruding member 42.

[0188] The process of assembling the first seal 81, the second cover 4, the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63 will be described below.

[0189] First, the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63 are moved through the second hole 43. The heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63 can move through the second hole 43 simultaneously or sequentially.

[0190] Since the second hole 43 is larger than the size of each of the heating contact portion 10a, the antenna contact portion 53 and the sensing contact portion 63, the heating contact portion 10a, the antenna contact portion 53 and the sensing contact portion 63 can easily pass through the second hole 43.

[0191] Next, the first seal 81 is inserted into the second hole 43. In this case, the heating contact portion 10a is inserted into the first penetration groove 812, the antenna contact portion 53 is located on the inner surface 4a of the second protruding member 42, and the sensing contact portion 63 can be inserted into the second penetration groove 813.

[0192] If the first seal 81 is inserted into the second hole 43 before the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63, it becomes difficult for the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63 to pass through the second hole 43. As a result, the process of assembling the first seal 81, the second cover 4, and the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63 cannot be easily performed.

[0193] Therefore, according to the embodiment, the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63 are first inserted into the second hole 43, and then the first seal 81 is inserted into the first hole 43. Therefore, the first seal 81, the second cover 4, and the heating contact portion 10a, the antenna contact portion 53, and the sensing contact portion 63 can be easily assembled.

[0194] Figure 17 This is a perspective view of the combination of a support, heater, and sensor of a heater assembly for an aerosol generating apparatus according to an embodiment.

[0195] refer to Figure 17 The heater 10 can be wrapped around the support member 9. Therefore, the support member 9 can support the heater 10.

[0196] In the heater assembly 1 for an aerosol generating apparatus according to an embodiment, the support member 9 may also support the sensor 6. For this purpose, the support member 9 may include a groove into which the bent member 62 of the sensor 6 is inserted. When the bent member 62 is inserted into the groove, the support member 9 can support the sensor 6. Therefore, the position of the sensor 6 can be fixed even when vibration or shaking is applied to the heater assembly 1 for an aerosol generating apparatus according to an embodiment, thus allowing the sensor 6 to stably sense the temperature of the heater 10 or the base 11.

[0197] For example, support member 9 may include a metallic material. For example, support member 9 may include a material such as SUS or aluminum. As another embodiment, support member 9 may include a polymer material with high heat resistance. For example, support member 9 may include materials such as PEEK, PPSU, and PC.

[0201] The filter rod 220 includes, but is not limited to, a single segment. In other words, the filter rod 220 may include multiple segments. For example, the filter rod 220 may include a first segment configured to cool the aerosol and a second segment configured to filter specific components contained in the aerosol. Additionally, the filter rod 220 may, as needed, include at least one segment configured to perform other functions.

[0202] The aerosol-generating article 200 can be packaged in at least one package 240. The package 240 may have at least one opening through which external air can be introduced or internal air can be exhausted. For example, the aerosol-generating article 200 can be packaged in a single package 240. As another example, the aerosol-generating article 200 can be double-packaged in two or more packages 240. For example, the tobacco stick 210 can be packaged in a first package 241, and the filter stick 220 can be packaged in packages 242, 243, and 244. Furthermore, the entire aerosol-generating article 200 can be repackaged in another single package 245. When the filter stick 220 comprises multiple segments, each segment can be packaged in packages 242, 243, and 244.

[0203] The tobacco stick 210 may include aerosol-generating substances. For example, the aerosol-generating substances may include at least one of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but are not limited thereto. Furthermore, the tobacco stick 210 may include other additives, such as flavoring agents, humectants, and / or organic acids. Moreover, the tobacco stick 210 may include flavored liquids, such as menthol or humectants, infused into the tobacco stick 210.
