[0002] There is an increasing demand for an aerosol generating device that generates an aerosol without burning a cigarette, which can generate an aerosol from an aerosol-generating substance without combustion, and the aerosol passes through a flavor medium before being discharged from the aerosol generating device.

[0003] An example of the aerosol generating device also includes a heated aerosol generating device that includes a heater that heats the aerosol product to generate the aerosol. Summary of the Invention [Problem to be solved by the invention]

[0004] The heat generated by the heater heating the aerosol product is transferred to the outside of the aerosol generator. In the case of an aerosol generator with poor thermal insulation, the heat generated by the heater is easily released to the outside. In this case, in order to continue heating the aerosol product at a preset temperature, the amount of power supplied to the heater must be increased, which increases the operating costs of the heater. Furthermore, the temperature felt by a user when holding the aerosol generator increases, making it difficult to realize a safe usage environment for the aerosol generator.

[0005] Therefore, in order to reduce the operating cost of the heater and realize safe use of the aerosol generating device, an aerosol generating device with improved thermal insulation performance is required.

An accommodating space for accommodating the aerosol product is formed by the first cover, the body, and the second cover, and a material for reflecting heat generated by the heater to the accommodating space may be deposited on at least a portion of the inner surface of at least one of the body, the first cover, and the second cover.

[0009] An aerosol generating device according to one embodiment includes a heater assembly for the aerosol generating device according to one embodiment, a battery that provides power to the heater assembly for the aerosol generating device, and a control unit that controls the operation of the heater assembly for the aerosol generating device. [Effects of the Invention]

[0010] The heater assembly for an aerosol generating device and the aerosol generating device according to the above-described embodiments can reduce the operating costs of the heater by improving the insulation performance and reducing the amount of power consumed to operate the heater.

[0011] Furthermore, the heater assembly for an aerosol generating device and the aerosol generating device according to the above-described embodiments can reduce the temperature that a user feels when holding the aerosol generating device, thereby improving the safety of the aerosol generating device.

[0042] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily implement and practice the present invention. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

[0043] FIG. 1 is a diagram illustrating an example in which an aerosol product is inserted into an aerosol generating device.

[0044] Referring to FIG. 1, an aerosol generating device 100 includes a battery 110, a control unit 120, and a heater assembly 1.

[0045] The aerosol generating device 100 further includes a vaporizer 130. An aerosol product 200 can be inserted into the internal space of the aerosol generating device 100.

[0046] The aerosol generating device 100 shown in Fig. 1 includes components related to this embodiment. Therefore, a person skilled in the art of this embodiment would understand that the aerosol generating device 100 may further include other general components in addition to the components shown in Fig. 1.

[0047] 1 shows the battery 110, the control unit 120, the vaporizer 130, and the heater assembly 1 arranged in a row. However, the internal structure of the aerosol generating device 100 is not limited to that shown in FIG. 1. In other words, the arrangement of the battery 110, the control unit 120, the heater assembly 1, and the vaporizer 130 can be changed depending on the design of the aerosol generating device 100.

[0048] When the aerosol production product 200 is inserted into the aerosol generation device 100, the aerosol generation device 100 can activate the heater assembly 1 and / or the vaporizer 130 to generate an aerosol from the aerosol production product 200 and / or the vaporizer 130. The aerosol generated by the heater assembly 1 and / or the vaporizer 130 passes through the aerosol production product 200 and is transmitted to the user.

[0049] If necessary, the aerosol generating device 100 can heat the heater assembly 1 even when the aerosol production item 200 is not inserted into the aerosol generating device 100 .

[0050] The battery 110 supplies power used to operate the aerosol generating device 100. For example, the battery 110 can supply power to heat the heater assembly 1 or the vaporizer 130, and can supply power necessary for the control unit 120 to operate. The battery 110 can also supply power necessary for the display, sensors, motors, etc. provided in the aerosol generating device 100 to operate.

[0051] The control unit 120 controls the overall operation of the aerosol generation device 100. Specifically, the control unit 120 controls the operation of not only the battery 110, the heater assembly 1, and the vaporizer 130, but also other components included in the aerosol generation device 100. The control unit 120 can also check the status of each component of the aerosol generation device 100 and determine whether the aerosol generation device 100 is in an operable state.

[0052] The control unit 120 includes at least one processor. The processor may be implemented as an array of multiple 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 controller 120 may also be implemented as other types of hardware.

[0053] The heater assembly 1 can be heated by power supplied from the battery 110. For example, if the aerosol production product 200 is inserted into the aerosol generating device 100, the heater assembly 1 can be located outside the aerosol production product 200. Thus, the heated heater assembly 1 can increase the temperature of the aerosol-generating material within the aerosol production product 200.

[0054] The heater assembly 1 may also be an electrical resistance heater. For example, the heater assembly 1 may include a conductive track, and the heater assembly 1 may be heated by passing an electric current through the conductive track. However, the heater assembly 1 is not limited to the above example, and may be any 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 a user.

[0055] As another example, the heater assembly 1 may be an induction heater. Specifically, the heater assembly 1 includes a heater 10 (FIGS. 4 to 6) for heating the aerosol product 200 by induction heating, and also includes a susceptor 11 (FIGS. 4 to 6) that can be heated by the heater 10. The heater 10 may also be a conductive coil.

[0056] In the following embodiments, the heater assembly 1 will be described based on an embodiment in which the heater assembly 1 is embodied as an induction heater, but this embodiment is not limited by the embodiment method of the heater assembly 1. For example, the heater assembly 1 may also be embodied as an electrical resistance heater.

[0057] For example, the heater assembly 1 may include a tube-type heating element, a plate-type heating element, a needle-type heating element, or a rod-type heating element, and depending on the configuration of the heating element, the inside or outside of the aerosol production article 200 may be heated.

[0058] Furthermore, a plurality of heater assemblies 1 may be arranged in the aerosol generation device 100. In this case, the plurality of heater assemblies 1 may be arranged so as to be inserted inside the aerosol production product 200, and may also be arranged outside the aerosol production product 200. Furthermore, some of the plurality of heater assemblies 1 may be arranged so as to be inserted inside the aerosol production product 200, and the rest may be arranged outside the aerosol production product 200.

[0059] Furthermore, the shape of the heater assembly 1 is not limited to the shapes shown in the drawings in this specification, but may be manufactured in a variety of shapes.

[0060] The vaporizer 130 can heat the liquid composition and generate an aerosol, which can pass through the aerosol product 200 and be delivered to a user. In other words, the aerosol generated by the vaporizer 130 can travel along an airflow passage of the aerosol generating device 100, which can be configured to allow the aerosol generated by the vaporizer 130 to pass through the aerosol product 200 and be delivered to a user.

[0061] For example, the vaporizer 130 may include, but is not limited to, a liquid storage unit, a liquid transfer means, and a heating element. For example, the liquid storage unit, the liquid transfer means, and the heating element may be included in the aerosol generation device 100 as separate modules.

[0062] The liquid storage unit can store a liquid composition. For example, the liquid composition can be a liquid containing a tobacco-containing substance including a volatile tobacco flavor component, or a liquid containing a non-tobacco substance. The liquid storage unit can be configured to be detachable from or attached to the vaporizer 130, or can be configured as an integral part of the vaporizer 130.

[0063] For example, the liquid composition may contain water, solvent, ethanol, plant extract, fragrance, flavoring, or vitamin mixture. The fragrance may include, but is not limited to, menthol, peppermint, spearmint oil, and various fruit flavoring ingredients. The flavoring may include ingredients that can provide the user with a variety of flavors or tastes. The vitamin mixture may include, but is not limited to, at least one of vitamin A, vitamin B, vitamin C, and vitamin E. The liquid composition may also include an aerosol-forming agent such as glycerin and propylene glycol.

[0064] The liquid transfer means can transfer the liquid composition in the liquid storage portion to the heating element, and can be, for example, but not limited to, a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic.

[0065] The heating element is an element for heating the liquid composition transferred by the liquid transfer means. For example, the heating element may be, but is not limited to, a metal hot wire, a metal hot plate, a ceramic heater, or the like. The heating element may also be formed of a conductive filament such as a nichrome wire, and may be arranged in a structure wound around the liquid transfer means. The heating element is heated by supplying an electric current and transfers heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, an aerosol may be generated.

[0066] For example, the vaporizer 130 may also be referred to as, but is not limited to, a cartomizer or an atomizer.

[0067] The aerosol generation device 100 may further include general-purpose components in addition to the battery 110, the control unit 120, the heater assembly 1, and the vaporizer 130. For example, the aerosol generation device 100 may include a display capable of outputting visual information and / or a motor for outputting tactile information. The aerosol generation device 100 may also include at least one sensor (such as a puff sensor, a temperature sensor, or an aerosol product insertion sensor). The aerosol generation device 100 may also be fabricated with a structure that allows external air to flow in or internal gas to flow out even when the aerosol product 200 is inserted.

[0068] 1, the aerosol generating device 100 can also be used to configure a system together with a separate cradle. For example, the cradle can be used to charge the battery 110 of the aerosol generating device 100. Alternatively, the heater assembly 1 can be heated when the cradle and the aerosol generating device 100 are coupled together.

[0069] The aerosol-producing article 200 may be similar to a typical combustion-type cigarette. For example, the aerosol-producing article 200 may be divided into a first portion containing an aerosol-generating material and a second portion containing a filter or the like. Alternatively, the second portion of the aerosol-producing article 200 may also contain an aerosol-generating material. For example, the aerosol-generating material in granular or encapsulated form may be inserted into the second portion.

[0070] The entire first part may be inserted into the aerosol generating device 100, and the second part may be exposed to the outside. Alternatively, only a portion of the first part may be inserted into the aerosol generating device 100, or the entire first part and a portion of the second part may be inserted into the aerosol generating device 100. A user can inhale the aerosol by 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.

[0071] As an example, external air may be introduced through at least one air passage formed in the aerosol generation device 100. For example, the opening and / or closing of the air passage formed in the aerosol generation device 100 and / or the size of the air passage may be adjusted by the user. This allows the user to adjust the amount of atomization, smoking sensation, etc. As another example, external air may be introduced into the aerosol product 200 through at least one hole formed in the surface of the aerosol product 200.

[0072] FIG. 2 is a front perspective view of a heater assembly for an aerosol generating device according to one embodiment, and FIG. 3 is a rear perspective view of the heater assembly for an aerosol generating device according to one embodiment.

[0073] 2 and 3, a heater assembly 1 for an aerosol generating device according to one embodiment includes a body 2, a first cover 3, and a second cover 4. However, the components of the heater assembly 1 are not limited thereto, and other components may be added or at least one component may be omitted depending on the embodiment.

[0074] The first cover 3 may be coupled to one side of the body 2. A holder 20 for supporting the aerosol product 200 may be coupled to the first cover 3.

[0075] The second cover 4 may be coupled to the other side of the body 2. That is, the first cover 3 and the second cover 4 may be coupled to different portions of the body 2.

[0076] The second cover 4 also includes a second cover body 41, a second protruding member 42, a second hole 43 and a sealing insertion groove 44.

[0077] The second cover body 41 can function as the main body of the second cover 4. The second cover body 41 can be connected to the body 2 so as to be disposed on the other side of the body 2. The second cover body 41 is generally disk-shaped, but this is merely an example, and the second cover body 41 can be formed in other shapes as long as it can be disposed on the other side of the body 2.

[0078] The second protruding member 42 may protrude from the second cover body 41. The second protruding member 42 may be formed integrally with the second cover body 41. The second protruding member 42 may be formed in an annular shape as a whole.

[0079] The second hole 43 may be formed in the second protruding member 42 so that at least one of the heating connection portion 10a of the heater 10, the antenna connection portion 53 of the antenna 5, and the sensing connection portion 63 of the sensing unit 6 shown in FIG. 8 of the heater 10 can pass through it. At least one of the connections (heating connection portion 10a, antenna connection portion 53, sensing connection portion 63) can pass through the second hole 43 and be electrically connected to the battery 110 or the control unit 120. The second hole 43 may be formed to penetrate the second cover body 41 and the second protruding member 42. The second hole 43 may be formed to be larger in size than each of the connections (heating connection portion 10a, antenna connection portion 53, sensing connection portion 63).

[0080] A portion of the lower seal 8 (FIG. 4) is inserted into the sealing insertion groove 44. The sealing insertion groove 44 may be formed on the outer surface of the second protruding member 42. One sealing insertion groove 44 may be formed on each of one and the other sides of the second protruding member 42.

[0081] FIG. 4 is an exploded perspective view of a heater assembly for an aerosol generating device according to one embodiment.

[0082] 4, the heater assembly 1 for an aerosol generating device according to one embodiment further includes an antenna 5, a sensing unit 6, a shielding unit 7, a lower ceiling 8, a support unit 9, a heater 10, a susceptor 11, and a holder 20. However, the components of the heater assembly 1 are not limited thereto, and other components may be added or at least one component may be omitted depending on the embodiment.

[0083] Figure 5 is a cross-sectional view of a heater assembly for an aerosol generating device according to one embodiment, shown based on line VV in Figure 2, and Figure 6 is a cross-sectional view of a heater assembly for an aerosol generating device according to one embodiment, shown based on line VI-VI in Figure 2.

[0084] Referring to Figures 5 and 6, a heater assembly 1 for an aerosol generating device according to one embodiment includes a heater 10 (e.g., a conductive coil) for heating an aerosol product 200, a body 2 arranged to surround the aerosol product 200, a first cover 3 arranged on one side of the body 2 and including a first hole 311 through which the aerosol product 200 is inserted, and a second cover 4 arranged on the other side of the body 2 and including a second hole 43 (Figures 3, 12 and 13) through which a wire for supplying power to the heater 10 passes to the outside of the heater assembly 1.

[0085] The first cover 3 is coupled to one side of the body 2, and the second cover 4 is coupled to the other side of the body 2, forming a receiving space 21 for receiving the aerosol product.

[0086] A material that reflects heat generated by the heater 10 to the accommodation space 21 is deposited on 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. As a result, the heater assembly 1 for an aerosol generating device according to one embodiment can achieve the following effects.

[0087] First, in the heater assembly 1 for an aerosol generation device according to one embodiment, the second cover 4, the first cover 3, and the body 2 are arranged to surround the outside of the heater 10, and thus can function as a physical barrier that prevents the heat generated by the heater 10 from being released to the outside. Therefore, the heater assembly 1 for an aerosol generation device according to one embodiment can improve the heat insulating performance through the physical barrier, and can reduce the amount of power consumed to operate the heater 10.

[0088] Second, the heater assembly 1 for an aerosol generating device according to an embodiment can reduce the amount of heat transferred to the aerosol generating device 100, thereby lowering the temperature that a user may feel when holding the aerosol generating device 100. Therefore, the heater assembly 1 for an aerosol generating device according to an embodiment can realize a safe usage environment when using the aerosol generating device 100.

[0089] Third, the deposition material can reflect the heat generated by the heater 10 to the accommodation space 21, thereby reducing the amount of heat generated by the heater 10 that is transferred to the outside. Therefore, the heater assembly 1 for an aerosol generating device according to one embodiment can further improve the heat insulating performance.

[0090] The three effects mentioned above can be demonstrated by the following experiment.

[0091] [experiment]

[0092] First, the temperature profile of the heater assembly 1 for an aerosol generating apparatus according to one embodiment is set so that the susceptor 11 is heated to 270° C. (Step 1).

[0093] Next, the susceptor 11 is heated for 270 seconds (step 2).

[0094] Next, repeat steps 1 and 2 three times in succession (step 3).

[0095] Next, after 5 minutes have passed, the temperature of the aerosol generating device 100 is measured (step 4).

[0096] Next, the above-described steps 1 to 4 are repeated (step 5) using a heater assembly according to the prior art (comparative example 1) and a heater assembly including a heat insulating structure for a vacuum tube (comparative example 2).

[0097] Table 1 below shows the results of the above experiment.

[0098] [Table 1]

[0099] As can be seen from Table 1 above, the heater assembly 1 for an aerosol generating device according to an embodiment has a temperature of the aerosol generating device 100 that is about 27°C lower than that of Comparative Example 1. This indicates that the heater assembly 1 for an aerosol generating device according to an embodiment improves the overall thermal insulation performance of the aerosol generating device 100 compared to the prior art. Furthermore, it can be seen that the heater assembly 1 for an aerosol generating device according to an embodiment has thermal insulation performance similar to that of Comparative Example 2, which includes a thermal insulation structure of a vacuum tube. Hereinafter, the body 2, the first cover 3, and the second cover 4 will be described in detail with reference to the accompanying drawings.

[0100] It should be noted that the terms "upper" and "lower" used in this specification are intended to distinguish the position of the lower structure of the heater assembly 1 for an aerosol generating device according to one embodiment, and do not refer to a specific direction.

[0101] 5 and 6, the body 2 is disposed outside the heater 10 so as to surround the heater 10. The body 2 may function to prevent heat generated in the heater 10 from being released to the outside.

[0102] A storage space 21 for storing the aerosol product 200 is formed inside the body 2. When the aerosol product 200 is stored in the storage space 21, the aerosol product 200 may be disposed inside the susceptor 11. When the heating connection portion 10a of the heater 10 is electrically connected to the battery 110 and the heater 10 heats the susceptor 11 using power supplied from the battery 110, the aerosol product 200 is heated by induction heating, thereby generating aerosol. The heating connection portion 10a also serves as a power line for supplying power to the heater 10. The susceptor 11 may be formed in a hollow cylindrical shape, but this is merely an example, and the susceptor 11 may be formed in other shapes as long as it can store the aerosol product 200. The susceptor 11 may be disposed inside the heater 10. The susceptor 11 may also include a metal material.

[0103] A material capable of reflecting heat generated by the heater 10 to the accommodation space 21 may be deposited on the inner surface of the body 2. The inner surface of the body 2 is also the side of the body 2 facing the heater 10. The material may include a metal material such as silver (Ag).

[0104] The body 2 may be formed generally in a hollow cylindrical shape, but this is merely an example, and the body 2 may be formed in other shapes as long as it can accommodate the heater 10. The body 2 may also include a metal material. For example, the body 2 may include a material such as stainless steel (SUS) or aluminum.

[0105] 5 and 6, the first cover 3 is disposed on one side of the body 2 to cover one side of the heater 10. The first cover 3 may function to prevent heat generated in the heater 10 from being dissipated to the outside of the heater assembly 1 through the one side of the body 2. The one side of the body 2 is also the upper part of the body 2.

[0106] The first cover 3 and one side of the body 2 can be joined together to form a receiving space 21 for receiving the aerosol product 200 .

[0107] A material capable of reflecting heat generated by the heater 10 to the receiving space 21 may be deposited on the inner surface of the first cover 3. The inner surface of the first cover 3 is also the side of the first cover 3 facing the heater 10.

[0108] The first cover 3 may also include a highly heat-resistant polymer material, such as polyether ether ketone (PEEK), polyphenyl sulfone (PPSU), or polycarbonate (PC).

[0109] 5 and 6, the first cover 3 also includes a first cover body 31. As shown in FIG.

[0110] The first cover body 31 can function as the main body of the first cover 3. The first cover body 31 can be coupled to the body 2 so as to be disposed on one side of the body 2. When the first cover body 31 is coupled to the body 2, the first cover body 31 can cover one side of the heater 10. Although the first cover body 31 is generally annular, this is merely an example, and the first cover body 31 can be formed in other shapes as long as it can be disposed on one side of the body 2 and cover the heater 10.

[0111] The first cover 3 further includes a first hole 311. The aerosol product 200 may be inserted into the first hole 311. The first hole 311 may be formed in the first cover body 31 so as to penetrate the top and bottom of the first cover body 31.

[0112] 5, the first cover 3 further includes a holder insertion groove 312. The holder 20 may be inserted into the holder insertion groove 312. When the holder 20 is inserted into the holder insertion groove 312, the holder 20 may be coupled to the first cover 3. The holder insertion groove 312 may be formed on an upper surface of the first cover body 31.

[0113] 6 , the first cover 3 further includes a first body insertion groove 313. One side of the body 2 may be inserted into the first body insertion groove 313. When one side of the body 2 is inserted into the first body insertion groove 313, the body 2 may be coupled to the first cover 3. As a result, the first cover 3 may support one side of the body 2. The first body insertion groove 313 may be formed on the bottom surface of the first cover main body 31.

[0114] 5 and 6, the first cover 3 further includes a cover heat insulating member 32. As shown in FIG.

[0115] The cover insulating member 32 extends along the longitudinal direction of the heater 10. The cover insulating member 32 may be disposed between the heater 10 and the body 2. As a result, the heater assembly 1 for an aerosol generating device according to an embodiment may implement a physical double barrier that prevents heat generated in the heater 10 from being released to the outside through the cover insulating member 32 and the body 2. The longitudinal direction of the heater 10 may refer to the direction in which the heater assembly 1 for an aerosol generating device according to an embodiment is relatively long.

[0116] The cover insulating member 32 may be extended in the longitudinal direction further than the heater 10. This allows the cover insulating member 32 to enclose the heater 10 over an increased area.

[0117] The cover heat insulating member 32 may be coupled to the first cover body 31 and extend along the longitudinal direction of the heater 10. The cover heat insulating member 32 may be formed integrally with the first cover body 31.

[0118] When the first cover 3 is coupled to one side of the body 2, the cover insulation member 32 may be inserted into the body 2 and disposed so as to surround a portion of the outside of the heater 10. That is, the side of the cover insulation member 32 may include an opening so that the heater 10 is partially surrounded by the cover insulation member 32.

[0119] As a result, in comparison with the comparative example in which the cover insulating member 32 surrounds the entire outside of the heater 10, the heater assembly 1 for an aerosol generation device according to the embodiment allows the cover insulating member 32 to be easily inserted into the body 2. This is because, in the process of inserting the cover insulating member 32 into the body 2, in the embodiment, there is less interference between the cover insulating member 32 and the body 2 compared to the comparative example. Therefore, in the heater assembly 1 for an aerosol generation device according to the embodiment, the first cover 3 and the body 2 can be easily assembled.

[0120] Referring to FIG. 6, the first cover 3 further includes a first protruding member 33 .

[0121] The first protruding members 33 may protrude outward from the first cover body 31. The first protruding members 33 may be disposed on both ends of the first cover body 31. The first protruding members 33, the cover insulation member 32, and the first cover body 31 may be integrally formed.

[0122] The first protruding member 33 also includes a coupling hole 331. A coupling member 3a (FIG. 7) for coupling the first cover 3 to the aerosol generation device 100 can be inserted into the coupling hole 331. The first cover 3 can be fixed to the aerosol generation device 100 by inserting the coupling member 3a into the coupling hole 331 and coupling it to the aerosol generation device 100. The coupling member 3a can also be a bolt. In this case, a screw thread can be formed on the inside of the first protruding member 33 facing the coupling hole 331.

[0123] 5 and 6, the 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 may function to prevent heat generated in the heater 10 from being dissipated to the outside of the heater assembly 1 through the other side of the body 2. The other side of the body 2 also serves as the lower part of the body 2.

[0124] The second cover 4 and the other side of the body 2 can be joined together to form the accommodation space 21. That is, the body 2, the first cover 3, and the second cover 4 can be arranged to completely surround the accommodation space 21 when joined together.

[0125] A material capable of reflecting heat generated by the heater 10 to the receiving space 21 may be deposited on the inner surface of the second cover 4. The inner surface of the second cover 4 is also the side of the second cover 4 facing the heater 10.

[0126] The second cover 4 may also include a highly heat-resistant polymer material, such as polyether ether ketone (PEEK), polyphenyl sulfone (PPSU), or polycarbonate (PC).

[0127] 5 and 6, the second cover 4 further includes a second body insertion groove 411.

[0128] The other side of the body 2 may be inserted into the second body insertion groove 411. When the other side of the body 2 is inserted into the second body insertion groove 411, the body 2 may be coupled to the second cover 4. As a result, the second cover 4 may support the other side of the body 2. The second body insertion groove 411 may be formed on the inside of the second cover main body 41.

[0129] Referring to FIGS. 5 and 6, the second cover 4 further includes an engaging member 412 .

[0130] The locking member 412 may be inserted into the cover insertion groove 22 formed in the body 2. When the locking member 412 is inserted into the cover insertion groove 22, the other side of the body 2 may be coupled to the second cover 4. This may securely couple the second cover 4 and the body 2 together. The locking member 412 may protrude from the second cover main body 41 toward the second body insertion groove 411. The locking member 412 may be formed integrally with the second cover main body 41.

[0131] 5 and 6, the antenna 5 recognizes whether or not the aerosol product 200 is contained in the containing space 21. The antenna 5 may be connected to the battery 110 and the control unit 120. The antenna 5 may also include a metal material.

[0132] For example, when the aerosol product 200 is accommodated in the accommodation space 21, the antenna 5 recognizes that the aerosol product 200 has been accommodated in the accommodation space 21, and can provide information regarding the accommodation state of the aerosol product 200 to the control unit 120. As a result, the control unit 120 can control the battery 110 to supply power to the heater 10.

[0133] As another example, if the aerosol product 200 is separated from the storage space 21, the antenna 5 recognizes that the aerosol product 200 has been separated and can provide information regarding the separated state of the aerosol product 200 to the control unit 120. As a result, the control unit 120 can control the battery 110 to cut off the power supplied to the heater 10.

[0134] The antenna 5 is disposed inside the body 2. The antenna 5 is disposed between the cover insulating member 32 and the shielding portion 7, and may be disposed so as to surround at least a portion of the heater 10. As a result, the heater assembly 1 for an aerosol generating device according to one embodiment can implement a physical triple barrier that prevents heat generated in the heater 10 from being released to the outside via the cover insulating member 32, the antenna 5, and the body 2.

[0135] 5 and 6, the sensing unit 6 senses the temperature of the heater 10 and / or the susceptor 11. The sensing unit 6 may be in contact with the susceptor 11 as shown in FIG. 5. The sensing unit 6 may be connected to the battery 110 or the control unit 120.

[0136] The sensing portion 6 is disposed inside the body 2 and may extend at least partially along the longitudinal direction of the heater 10. The sensing portion 6 may also include a metal material.

[0137] Referring to FIG. 5, the sensing unit 6 also includes a sensing body 61 and a bent member 62 .

[0138] The sensing body 61 extends at least partially along the longitudinal direction of the heater 10. The sensing body 61 may be disposed between the body 2 and the shielding portion 7.

[0139] The bent member 62 extends toward the susceptor 11 so that the sensing portion 6 abuts against the susceptor 11. The bent member 62 may pass between the first cover 3 and the support portion 9 and extend toward the susceptor 11. The bent member 62 may be connected to the upper side of the sensing body 61.

[0140] 5 and 6, the shielding portion 7 is disposed inside the body 2. The shielding portion 7 is disposed between the body 2 and the antenna 5, and is disposed so as to surround at least a portion of the heater 10. As a result, the heater assembly 1 for an aerosol generating device according to one embodiment can achieve the following effects.

[0141] First, in the heater assembly 1 for an aerosol generation device according to one embodiment, the shielding part 7 is disposed outside the antenna 5, thereby reducing the possibility that the antenna 5 will detect an electronic device located outside the shielding part 7. Therefore, in the heater assembly 1 for an aerosol generation device according to one embodiment, the antenna 5 can detect only whether or not an aerosol product 200 is contained, thereby improving the overall performance of the antenna 5.

[0142] Second, the heater assembly 1 for an aerosol generating device according to an embodiment can implement a physical quadruple barrier that prevents heat generated in the heater 10 from being released to the outside through the cover insulating member 32, the antenna 5, the shielding part 7, and the body 2. Therefore, the heater assembly 1 for an aerosol generating device according to an embodiment can further improve the heat insulating performance.

[0143] The shielding portion 7 may also include a metal material, such as aluminum (Al) or silver (Ag).

[0144] 5 and 6, the lower sealing 8 functions to seal the gap between at least one of the connection parts (heating connection part 10a, antenna connection part 53, sensing connection part 63 (FIG. 8)) and the second cover 4. The lower sealing 8 may be attached to the second cover 4. The lower sealing 8 may be attached to the outside of the second protruding member 42 and the inside of the second protruding member 42. The lower sealing 8 may also include a rubber material. The lower sealing 8 may also include a first sealing 81 and a second sealing 82, which will be described in detail later.

[0145] 5 and 6, the support 9 is disposed inside the heater 10 and supports the heater 10. The heater 10 may be coupled to the support 9. The support 9 may be formed in a hollow cylindrical shape as a whole, but this is merely an example, and the support 9 may be formed in other shapes as long as it can support the heater 10.

[0146] The susceptor 11 may be disposed inside the support 9. Therefore, the support 9 may also function to prevent heat generated in the susceptor 11 from being released to the outside.

[0147] 4 to 6, the heater assembly 1 for an aerosol generating device according to an embodiment further includes a first sealing ring 30, a second sealing ring 40, and a third sealing ring 50.

[0148] The first sealing ring 30 may be disposed between the holder 20 and the first cover 3. The first sealing ring 30 may perform the function of sealing between the holder 20 and the first cover 3.

[0149] The second sealing ring 40 may be disposed on 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 product 200 may be inserted into the second sealing ring 40. When the aerosol product 200 is accommodated in the accommodation space 21, the second sealing ring 40 can seal the aerosol product 200 and the first cover body 31.

[0150] The third sealing ring 50 may be disposed at the lower end of the susceptor 11 inside the support 9. At least a portion of the aerosol product 200 may be inserted into the third sealing ring 50. When the aerosol product 200 is accommodated in the accommodation space 21, the third sealing ring 50 can seal the aerosol product 200 and the support 9.

[0151] Each of the first sealing ring 30, the second sealing ring 40, and the third sealing ring 50 may include a rubber material. Each of the first sealing ring 30, the second sealing ring 40, and the third sealing ring 50 may be formed in a circular ring shape, but there is no limitation on the shape.

[0152] FIG. 7 is a perspective view of a first cover, a heater, and a holder in a heater assembly for an aerosol generating device according to one embodiment.

[0153] The holder 20 functions to support the aerosol product 200. The holder 20 also includes an insertion hole 20a into which the aerosol product 200 is inserted, a ridge 20b that protrudes toward the insertion hole 20a and supports the aerosol product 200, and a holder protrusion 20c that protrudes toward the first cover body 31 to be inserted into the holder insertion groove 312. When the holder protrusion 20c is inserted into the holder insertion groove 312, the holder 20 can be coupled to the first cover body 31.

[0154] When the holder 20 is coupled to the first cover body 31 , the insertion hole 20 a of the holder 20 may be connected to the first hole 311 of the first cover body 31 .

[0155] The holder 20 also includes a plurality of ridges 20b. The ridges 20b may be arranged along the circumferential direction of the holder 20 so as to be spaced apart from one another.

[0156] Figure 8 is a perspective view of the heater, antenna, and sensing unit combined in a heater assembly for an aerosol generating device according to one embodiment, and Figure 9 is a perspective view of the first cover and antenna combined in a heater assembly for an aerosol generating device according to one embodiment.

[0157] 8 and 9, the antenna 5 also includes an antenna body 51, an antenna extension portion 52, and an antenna connection portion 53.

[0158] 8, the antenna body 51 extends along the longitudinal direction of the heater 10 and is disposed so as to surround a portion of the heater 10. That is, the side surface of the antenna body 51 also includes an opening so that the heater 10 is partially surrounded by the antenna body 51.

[0159] Therefore, in comparison with the comparative example in which the antenna body 51 surrounds the entire heater 10, the heater assembly 1 for an aerosol generation device according to the embodiment allows the antenna body 51 to be easily inserted into the body 2. This is because, in the heater assembly 1 for an aerosol generation device according to the embodiment, interference between the antenna body 51 and the body 2 is small during the process of inserting the antenna body 51 into the body 2, compared with the comparative example. Therefore, in the heater assembly 1 for an aerosol generation device according to the embodiment, the antenna 5 and the body 2 can be easily assembled.

[0160] When the antenna body 51 extends along the longitudinal direction of the heater 10 and is disposed so as to surround a portion of the heater 10, the cover insulation member 32 can be disposed at a position corresponding to the antenna body 51, as shown in Fig. 9. This allows the antenna body 51 to support the cover insulation member 32 on the outside of the cover insulation member 32.

[0161] The antenna extension 52 is connected to the antenna body 51. The antenna extension 52 includes a first extension extending from one side of the antenna body 51 along the circumferential direction of the heater 10, and a second extension extending from the other side of the antenna body 51 along the circumferential direction of the heater 10.

[0162] 8, the antenna 5 also includes a passing portion 5a through which the bent member 62 of the sensing unit 6 passes. As a result, in the heater assembly 1 for an aerosol generating device according to an embodiment, the sensing unit 6 is in contact with the susceptor 11 located inside the heater 10 and is not electrically connected to the antenna 5. Therefore, the heater assembly 1 for an aerosol generating device according to an embodiment can reduce the possibility of an electrical short circuit occurring between the antenna 5 and the sensing unit 6. The passing portion 5a is also a space located between the first extension portion and the second extension portion.

[0163] 8 and 9, the antenna connection part 53 is disposed at a position spaced apart from the antenna extension part 52 and is connected to the antenna main body 51. The antenna connection part 53 may be connected to the battery 110 and / or the control part 120. The antenna connection part 53 may also include a first connection member extending in a direction transverse to the longitudinal direction of the heater 10 and a second connection member extending in the longitudinal direction of the heater 10. The antenna connection part 53, the antenna extension part 52, and the antenna main body 51 may be integrally formed.

[0164] FIG. 10 is a perspective view of an antenna, a sensing portion, and a shielding portion combined together in a heater assembly for an aerosol generating device according to one embodiment.

[0165] 10, the sensing unit 6 also includes a sensing body 61, a bending member 62, and a sensing connection portion 63. In the following, redundant explanations regarding the sensing body 61 and the bending member 62 previously described in FIG. 5 will be omitted.

[0166] The sensing body 61 also includes a first body extending along the longitudinal direction of the heater 10, a second body connected to the first body and extending along a direction transverse to the longitudinal direction, and a third body connected to the second body and connected to the sensing connection portion 63.

[0167] The bending member 62 also includes a first bending member extending in a direction transverse to the longitudinal direction, and a second bending member connected to the first bending member and bent downward toward the susceptor 11.

[0168] The sensing connection part 63 may be connected to the underside of the sensing body 61. The sensing connection part 63 may be connected to the battery 110 and / or the control unit 120. The sensing connection part 63 may include two connection members extending in different directions. The sensing connection part 63, the bent member 62, and the sensing body 61 may be integrally formed.

[0169] Referring to FIG. 10, the shielding part 7 also includes a shielding body 71 and a sensing part passage groove 72.

[0170] The shielding body 71 can form the overall outer shape of the shielding portion 7. The shielding body 71 can be arranged inside the body 2 so as to surround the antenna 5. The shielding body 71 can be formed in a hollow cylindrical shape overall, but this is merely an example, and the shielding body 71 can also be formed in other shapes as long as it can be arranged outside the antenna 5.

[0171] The sensing unit passing groove 72 is also a space through which the bent member 62 passes. As a result, the heater assembly 1 for an aerosol generating device according to an embodiment also includes a structure in which the sensing unit 6 comes into contact with the susceptor 11 located inside the shielding unit 7 when the shielding unit 7 and the sensing unit 6 are not electrically connected to each other during the process of the sensing unit 6 abutting against the susceptor 11. Therefore, the heater assembly 1 for an aerosol generating device according to an embodiment can reduce the possibility of an electrical short circuit occurring between the shielding unit 7 and the sensing unit 6. The sensing unit passing groove 72 may be formed in the shielding body 71.

[0172] FIG. 11 is a rear perspective view of a heater assembly for an aerosol generating device according to one embodiment.

[0173] 11, the connections (heating connection 10a, antenna connection 53, and sensing connection 63) pass through the second holes 43 (FIGS. 3, 12, and 13), and the lower seal 8 serves to seal at least one of the connections (heating connection 10a, antenna connection 53, and sensing connection 63) and the second cover 4. The lower seal 8 may be coupled to the second protruding member 42.

[0174] Figure 12 is an exploded oblique view of the second cover and lower sealing in a heater assembly for an aerosol generating device according to one embodiment, and Figure 13 is a drawing illustrating the second cover in a heater assembly for an aerosol generating device according to one embodiment.

[0175] Referring to FIG. 12, the lower seal 8 includes a first seal 81 inserted into the second hole 43 and a second seal 82 spaced apart from the first seal 81 .

[0176] The first seal 81 is inserted into the second hole 43 and can contact the inner surface 4a (FIG. 13) of the second protruding member 42, sealing the second hole 43. Therefore, the first seal 81 can prevent heat generated by the heater 10 from being dissipated downward through the second hole 43. The inner surface 4a is also one surface of the second protruding member 42 facing the second hole 43.

[0177] The first seal 81 may be inserted into the second hole 43 using an interference fit, thereby improving the sealing force of the first seal 81 for the aerosol generating device according to an embodiment to seal the second hole 43.

[0178] The second ceiling 82 is disposed so as to be spaced apart from the first ceiling 81. The second ceiling 82 may be coupled to the outer surface 4b (FIG. 13) of the second protruding member 42, which is the opposite surface to the inner surface 4a. The outer surface 4b of the second protruding member 42 may be flush with the outer surface of the second cover 4. The second ceiling 82 may be disposed so as to surround the second protruding member 42.

[0179] FIG. 14 is a view illustrating a first sealing in a heater assembly for an aerosol generating device according to one embodiment.

[0180] Referring to FIG. 14, the first seal 81 includes a first seal body 811 , a first passage groove 812 and a second passage groove 813 .

[0181] The first sealing body 811 is inserted into the second hole 43. A first passage groove 812 and a second passage groove 813 may be formed in the first sealing body 811. The first sealing body 811 may be formed in a rectangular parallelepiped shape as a whole, but may be formed in other shapes as long as it can be inserted into the second hole 43.

[0182] The first passage groove 812 may be formed in the first sealing body 811 so that the heating connection part 10a can pass through. The first passage groove 812 may be formed by machining a groove to a predetermined depth from the outer surface of the first sealing body 811. Although two first passage grooves 812 are shown in FIG. 14, this is merely an example, and the number of first passage grooves 812 that may be formed is not limited.

[0183] The second passage groove 813 is formed in the first sealing body 811 at a position spaced apart from the first passage groove 812, and the sensing connection part 63 can pass through the second passage groove 813. The second passage groove 813 can be formed by machining a groove to a predetermined depth from the outer surface of the first sealing body 811. Although one second passage groove 813 is illustrated in FIG. 14, this is merely an example, and there is no limit to the number of second passage grooves 813 that can be formed.

[0184] FIG. 15 is a diagram illustrating a second sealing in a heater assembly for an aerosol generating device according to one embodiment.

[0185] Referring to FIG. 15, the second seal 82 also includes a second seal body 821, a second cover insertion groove 822, and a seal protrusion 823.

[0186] The second sealing body 821 is coupled to the second protruding member 42 of the second cover 4. The second sealing body 821 may have a second cover insertion groove 822 and a sealing protrusion 823. The second sealing body 821 may function as the body of the second seal 82.

[0187] The second protruding member 42 of the second cover 4 can be inserted into the second cover insertion groove 822. For example, the second protruding member 42 can be inserted into the second cover insertion groove 822 by an interference fit. In this case, no gap is formed between the second protruding member 42 and the second sealing body 821.

[0188] The sealing protrusions 823 protrude toward the second cover insertion grooves 822. When the second protruding member 42 of the second cover 4 is inserted into the second cover insertion grooves 822 of the second seal 82, the sealing protrusions 823 are inserted into the sealing insertion grooves 44 formed on the outer surface 4b of the second protruding member 42 (FIG. 12). This may result in a firm connection between the second cover 4 and the second seal 82. The sealing protrusions 823 may be formed at different positions on the inner surface of the second seal body 821. The sealing protrusions 823 may be formed integrally with the second seal body 821.

[0189] FIG. 16 is a cross-sectional view of a heater assembly for an aerosol generating device according to one embodiment, taken along line XVI-XVI in FIG.

[0190] When the first sealing member 81 is inserted into the second hole 43, as shown in Figure 16, the connection parts (heating connection part 10a, antenna connection part 53, sensing connection part 63) can be arranged between the first sealing member 81 and the second cover 4. Therefore, even if vibration or shaking acts on the heater assembly 1 for an aerosol generating device according to one embodiment, the movement of the connection parts (heating connection part 10a, antenna connection part 53, sensing connection part 63) can be restricted.

[0191] When the first sealing member 81 is inserted into the second hole 43 in an interference fit manner, the first sealing member 81 can press the connection portions (heating connection portion 10a, antenna connection portion 53, sensing connection portion 63) toward the inner surface 4a of the second protruding member 42.

[0192] The assembly process of the first sealing 81, the second cover 4, and the connection parts (heating connection part 10a, antenna connection part 53, and sensing connection part 63) will be described below.

[0193] First, the connections (heating connection 10a, antenna connection 53, and sensing connection 63) are passed through the second hole 43. The heating connection 10a, antenna connection 53, and sensing connection 63 can pass through the second hole 43 simultaneously or sequentially.

[0194] Since the second hole 43 is larger than the size of each of the connection parts (heating connection part 10a, antenna connection part 53, sensing connection part 63), the connection parts (heating connection part 10a, antenna connection part 53, sensing connection part 63) can easily pass through the second hole 43.

[0195] Next, the first seal 81 is inserted into the second hole 43. In this case, the heating connection portion 10a is inserted into the first passage groove 812, the antenna connection portion 53 is located on the inner surface 4a of the second protruding member 42, and the sensing connection portion 63 is inserted into the second passage groove 813.

[0196] If the first sealing 81 is inserted into the second hole 43 before the connecting parts (heating connecting part 10a, antenna connecting part 53, sensing connecting part 63), it is difficult to pass the connecting parts (heating connecting part 10a, antenna connecting part 53, sensing connecting part 63) through the second hole 43. As a result, in this case, the assembly process of the first sealing 81, the second cover 4, and the connecting parts (heating connecting part 10a, antenna connecting part 53, sensing connecting part 63) is not easy.

[0197] However, according to one embodiment, the connection parts (heating connection part 10a, antenna connection part 53, sensing connection part 63) are inserted into the second hole 43 first, and then the first sealing 81 is inserted into the second hole 43. Therefore, the first sealing 81, the second cover 4, and the connection parts (heating connection part 10a, antenna connection part 53, sensing connection part 63) can be easily assembled.

[0198] FIG. 17 is a perspective view of a heater assembly for an aerosol generating device according to one embodiment, showing a support portion, a heater, and a sensing portion combined together.

[0199] 17, the heater 10 is wound around the support portion 9. In this way, the support portion 9 can support the heater 10.

[0200] The support part 9 in the heater assembly 1 for an aerosol generation device according to one embodiment can also support the sensing part 6. To this end, the support part 9 also includes a groove into which the bent member 62 of the sensing part 6 is inserted. By inserting the bent member 62 into the groove, the support part 9 can support the sensing part 6. As a result, even if the heater assembly 1 for an aerosol generation device according to one embodiment is subjected to vibration or shaking, the position of the sensing part 6 can be fixed, and the sensing part 6 can stably sense the temperature of the heater 10 or the susceptor 11.

[0201] As an example, the support portion 9 may include a metal material. For example, the support portion 9 may include a material such as stainless steel (SUS) or aluminum. As another example, the support portion 9 may include a highly heat-resistant polymer material. For example, the support portion 9 may include a material such as polyether ether ketone (PEEK), polyphenyl sulfone (PPSU), or polycarbonate (PC).

[0202] An example of an aerosol product 200 will now be described with reference to FIGS.

[0203] 18 and 19 are diagrams illustrating examples of aerosol products.

[0204] 18, the aerosol production article 200 includes a tobacco rod 210 and a filter rod 220. The first portion described with reference to FIG.

[0205] 18 illustrates filter rod 220 as a single segment, but is not limited to this. In other words, filter rod 220 may be composed of multiple segments. For example, filter rod 220 may include a first segment that cools the aerosol and a second segment that filters a specific component contained in the aerosol. Optionally, filter rod 220 may also include at least one additional segment that performs another function.

[0206] The aerosol product 200 may be wrapped using at least one wrapper 240. The wrapper 240 may have at least one hole formed therein through which external air can enter or internal gas can escape. As an example, the aerosol product 200 may be wrapped using a single wrapper 240. As another example, the aerosol product 200 may be wrapped using two or more wrappers 240 in a stacked manner. For example, the tobacco rod 210 may be wrapped using a first wrapper 241, and the filter rod 220 may be wrapped using wrappers 242, 243, and 244. The entire aerosol product 200 may then be wrapped using a single wrapper 245. If the filter rod 220 is composed of multiple segments, each segment may be wrapped using a wrapper 242, 243, or 244.

[0207] The tobacco rod 210 includes an aerosol-forming material. For example, the aerosol-forming material may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but is not limited thereto. The tobacco rod 210 may also include other additives, such as flavoring agents, humectants, and / or organic acids. A flavoring liquid, such as menthol or a humectant, may also be added to the tobacco rod 210 by spraying it onto the tobacco rod 210.

[0208] The tobacco rod 210 can be manufactured in various ways. For example, the tobacco rod 210 can be manufactured from a sheet or a strand. The tobacco rod 210 can also be manufactured from shredded tobacco, which is a tobacco sheet cut into small pieces. The tobacco rod 210 can also be surrounded by a thermally conductive material. For example, the thermally conductive material can be a metal foil such as aluminum foil, but is not limited to this. For example, the thermally conductive material surrounding the tobacco rod 210 can evenly distribute heat transferred to the tobacco rod 210 and improve the thermal conductivity of the tobacco rod, thereby improving the tobacco taste. The thermally conductive material surrounding the tobacco rod 210 can also function as a susceptor heated by an induction heater. In this case, although not shown in the drawings, the tobacco rod 210 can also include an additional susceptor in addition to the thermally conductive material surrounding the exterior.

[0209] The filter rod 220 is also a cellulose acetate filter. The shape of the filter rod 220 is not limited. For example, the filter rod 220 may be a cylindrical rod or a tube-type rod having a hollow interior. The filter rod 220 may also be a recess-type rod. If the filter rod 220 is composed of multiple segments, at least one of the multiple segments may be manufactured in a different shape.

[0210] The filter rod 220 may be manufactured to produce a flavor. For example, a flavoring liquid may be sprayed onto the filter rod 220, and a separate fiber coated with the flavoring liquid may be inserted into the filter rod 220.

[0211] The filter rod 220 also includes at least one capsule 230. The capsule 230 can generate a flavor or an aerosol. For example, the capsule 230 can be a structure in which a liquid containing a flavoring agent is enclosed in a coating. The capsule 230 can have a spherical or cylindrical shape, but is not limited thereto.

[0212] If the filter rod 220 includes a segment for cooling the aerosol, the cooling segment can be made of a polymeric or biodegradable polymeric material. For example, the cooling segment can be made of pure polylactic acid, but is not limited thereto. Alternatively, the cooling segment can be made of a cellulose acetate filter with multiple holes. However, the cooling segment is not limited to the above examples and can be any material that can perform the function of cooling the aerosol.

[0213] 19, the aerosol production product 300 further includes a front end plug 330. The front end plug 330 may be located on one side of the tobacco rod 310 opposite the filter rod 320. The front end plug 330 may prevent the tobacco rod 310 from detaching to the outside and may prevent liquefied aerosol from flowing out of the tobacco rod 310 into the aerosol generation device 100 (FIG. 1) during smoking.

[0214] Filter rod 320 also includes first segment 321 and second segment 322. Here, first segment 321 may correspond to the first segment of filter rod 220 in FIG. 18, and second segment 322 may correspond to the second segment of filter rod 220 in FIG.

[0215] The diameter and overall length of the aerosol product article 300 can correspond to the diameter and overall length of the aerosol product article 200 of Figure 18. For example, but not limited to, the length of the front end plug 330 can be about 7 mm, the length of the tobacco rod 310 can be about 15 mm, the length of the first segment 321 can be about 12 mm, and the length of the second segment 322 can be about 14 mm.

[0216] The aerosol product 300 may be wrapped by at least one wrapper 350. The wrapper 350 may have at least one hole formed therein through which external air can flow in or internal gas can flow out. For example, the front end plug 330 may be wrapped by a first wrapper 351, the tobacco rod 310 may be wrapped by a second wrapper 352, the first segment 321 may be wrapped by a third wrapper 353, and the second segment 322 may be wrapped by a fourth wrapper 354. The entire aerosol product 300 may then be wrapped by a fifth wrapper 355.

[0217] In addition, at least one perforation 360 may be formed in the fifth wrapper 355. For example, but not limited to, the perforation 360 may be formed in the area surrounding the tobacco rod 310. The perforation 360 may serve to transfer heat generated by the heater assembly 1 shown in FIG. 1 to the interior of the tobacco rod 310.

[0218] The second segment 322 also includes at least one capsule 340. The capsule 340 can generate a flavor or an aerosol. For example, the capsule 340 can have a structure in which a liquid containing a flavoring agent is enclosed in a coating. The capsule 340 can have a spherical or cylindrical shape, but is not limited thereto.

[0219] An embodiment may also be embodied in the form of a recording medium containing computer-executable instructions, such as a program module executed by a computer. Computer-readable media are any available media that can be accessed by a computer, including both volatile and nonvolatile media, and both detachable and non-detachable media. Computer-readable media also include both computer recording media and communication media. Computer recording media include both volatile and non-volatile, detachable and non-detachable media embodied in any method or technology for storing information, such as computer-readable instructions, data structures, program modules, or other data. Communication media typically include computer-readable instructions, data structures, other data in a modulated data signal, such as a program module, or other transmission mechanism, and include any information delivery media.
