[0063] Figure 1 This is a front view of an aerosol generating apparatus, to which a vaporizer according to an embodiment is connected.

[0064] refer to Figure 1According to the embodiment, the vaporizer 1 and the body 2 can be combined with each other to operate as an aerosol generating device 1000. For example, the vaporizer 1 can be connected to a region of the body 2. The connection direction of the vaporizer 1 is not limited to... Figure 1 The example shown is illustrated, and the vaporizer 1 can be connected to the body 2 along the longitudinal direction of the aerosol generating device 1000.

[0065] In one embodiment, the aerosol generating device 1000 may include a processor (not shown) and a battery (not shown). The battery and the processor may be electrically connected to the vaporizer 1. For example, the battery may supply power to the vaporizer 1, and the processor may control the vaporizer 1. Therefore, the aerosol generating device 1000 can generate aerosols by heating a liquid or gel-like aerosol-generating substance stored in the vaporizer 1.

[0066] In another embodiment, the aerosol generating apparatus 1000 may further include: a housing including a receiving space (not shown) in which an aerosol generating article (e.g., a cigarette) is inserted; and a separate heater (not shown) for heating the aerosol generating article contained in the housing.

[0067] For example, the containment space and heater can be located within the body 2. The vaporizer 1 can be connected to one region of the body 2, while the aerosol generating article can be inserted into another region of the body 2.

[0068] The aerosol generating apparatus 1000 can generate aerosols not only by using the vaporizer 1, but also by using an inserted aerosol generating article. Therefore, the aerosol generating apparatus 1000 can be implemented as a hybrid aerosol generating apparatus.

[0069] In another embodiment, the aerosol generating device 1000 may further include a removable cover (not shown) for protecting at least a portion of the body 2 and the vaporizer 1 connected to the body 2. The removable cover may be attached to an end portion of the aerosol generating device 1000 where the vaporizer 1 and the body 2 are connected to each other. For example, a user can detach the removable cover, which is separate from the body 2, to replace the vaporizer 1.

[0070] Figure 2A for Figure 1 The exploded perspective view of the vaporizer 1 shown, and Figure 2B for Figure 1 The bottom perspective view of the vaporizer 1 shown.

[0071] refer to Figure 2A and Figure 2BThe vaporizer 1 according to the embodiment may include a storage unit 10, a sealing unit 20, a core 30, a heating element 40, a housing unit 50, and a cover 60. The storage unit 10, sealing unit 20, core 30, heating element 40, housing unit 50, and cover 60 may be configured as follows: Figure 2A and Figure 2B Combine the z-axis directions shown.

[0072] For example, after housing the heating element 40 and the core 30 in the housing unit 50, the housing unit 50 can be inserted into the cover 60, and the sealing unit 20 can be connected to the housing unit 50. Therefore, the sealing unit 20 and the housing unit 50 can be located within the cover 60. Finally, the storage unit 10 and the cover 60 can be connected to each other to assemble the vaporizer 1. However, the assembly sequence and connection method of the vaporizer 1 are not limited to the above example.

[0073] Storage unit 10 can store aerosol-generating substances. Storage unit 10 can store aerosol-generating substances in liquid or gel state. Aerosol-generating substances stored in storage unit 10 can be transferred to core 30 and absorbed by core 30, and aerosol-generating substances absorbed by core 30 can be heated by heating element 40 to be converted into aerosols.

[0074] At least one area of ​​the storage unit 10 may include an opening. For example, the bottom surface of the storage unit 10 or at least a portion of the bottom surface may have an opening, allowing the aerosol-generating material to move naturally to the outside of the storage unit 10 by gravity.

[0075] According to an embodiment, the storage unit 10 can be connected to a sealing unit 20 to prevent leakage of aerosol-generating substances. By connecting the sealing unit 20 to at least one region of the storage unit 10 (e.g., the open side of the storage unit 10), the sealing unit 20 and the storage unit 10 can form a storage space 12 for containing aerosol-generating substances.

[0076] The sealing unit 20 may be made of a material that enables a tight connection between the sealing unit 20 and the storage unit 10. For example, the sealing unit 20 may be made of an elastic material such as rubber or silicone, but is not limited thereto.

[0077] The sealing unit 20 can be tightly connected to the storage unit 10 to prevent leakage of aerosol-generating substances. That is, the sealing unit 20 is firmly connected to the storage unit 10 such that there is no gap between the storage unit 10 and the receiving unit 50.

[0078] The sealing unit 20 can be manufactured to be detachable from the storage unit 10, or it can be manufactured integrally with the storage unit 10.

[0079] The sealing unit 20 may have at least one opening 22 so that when the storage unit 10 is connected to the sealing unit 20, the aerosol generating material stored in the storage unit 10 can move to the outside of the storage unit 10.

[0080] For example, the storage unit 10 includes an open side that exposes the storage space to the outside, and a sealing unit 20 having an opening 22 can be connected to the open side of the storage unit 10. Therefore, aerosol-generating substances stored in the storage space 12 of the storage unit 10 can move to the outside of the storage unit 10 through the opening 22 formed in the sealing unit 20, and leakage of aerosol-generating substances stored in the storage unit 10 to the outside of the storage unit 10 through gaps other than the opening 22 can be prevented.

[0081] The core 30 can receive and absorb aerosol-generating substances from the storage unit 10. The core 30 can have an elongated shape. For example, the core 30 can have a columnar shape extending in one direction. Specifically, the core 30 can have a polygonal columnar shape, such as a cylindrical, quadrilateral, or triangular columnar shape, but is not limited thereto. For example, the core 30 can have a rod-like, needle-like, or planar shape.

[0082] A portion of the core 30 can absorb aerosol-generating substances supplied from the storage unit 10. For example, the aerosol-generating substances absorbed into a portion of the core 30 can move to another portion of the core 30 via capillary action. The core 30 can comprise various types of materials. For example, the core 30 can comprise at least one of cotton, ceramic, and glass fiber.

[0083] In one embodiment, the core 30 may include a first end portion 31, a second end portion 33, and a central portion 32 located between the first end portion 31 and the second end portion 33. Aerosol-generating material supplied from the storage unit 10 can be absorbed by the core 30 through the first end portion 31 and the second end portion 33. The aerosol-generating material absorbed by the core 30 can move to the central portion 32 of the core 30.

[0084] The heating element 40 can heat the aerosol-generating material absorbed into the core 30 and generate aerosols. The heating element 40 can be disposed near the core 30. The heating element 40 can generate aerosols by heating the liquid aerosol-generating material conveyed to the central portion 32 of the core 30.

[0085] For example, the heating element 40 may be a resistance heater in the form of a coil wound around the outer circumferential surface of the central portion 32 of the core 30. As another example, the heating element 40 may be a resistance heater printed on the central portion 32 of the core 30. The heating element 40 is not limited to the above examples and may be a porous element integrally formed with the core 30.

[0086] The receiving unit 50 may include receiving spaces 51, 52, and 53 for receiving the core 30 and the heating element 40. For example, the receiving unit 50 may include: at least one support groove 52 for supporting at least a portion of the core 30; at least one storage groove 51 for temporarily storing the aerosol generating material to transfer the aerosol generating material to the core 30; and a central space 53 for receiving the central portion 32 of the core 30.

[0087] At least a portion of the core 30 may be located in a cavity surrounded by the housing unit 50 and the sealing unit 20. For example, the central portion 32 of the core 30 around which the heating element 40 is wound may be placed in the cavity, and thus an aerosol may be generated in the cavity.

[0088] External air can be introduced into the interior of the housing unit 50 through the inlet 56, and the aerosol generated in the cavity can be discharged to the outside of the housing unit 50 through the outlet 57.

[0089] A more detailed description of the accommodating unit 50 and the supporting recess 52 and storage recess 51 within the accommodating unit 50 will be given with reference to the other accompanying drawings.

[0090] The cover 60 can be coupled to the receiving unit 50 and the sealing unit 20. The cover 60 may include an internal space 62 in which the receiving unit 50 and the sealing unit 20 can be disposed. For example, the cover 60 may include an internal space 62 having a shape corresponding to the external shape of the receiving unit 50 and the sealing unit 20. The receiving unit 50 and the sealing unit 20 can be properly aligned with each other and disposed within the internal space 62 of the cover 60, thereby protecting the receiving unit 50 and the sealing unit 20 from external impacts.

[0091] The cover 60 may include a connecting channel 64 for guiding aerosol discharged from the outlet 57 of the containment unit 50 to the outside of the vaporizer 1. For example, with the containment unit 50 disposed within the internal space 62 of the cover 60, the connecting channel 64 may be located at a position corresponding to the outlet 57, such that the outlet 57 communicates with the connecting channel 64. The aerosol discharged through the outlet 57 to the outside of the containment unit 50 may move along the connecting channel 64 to the outside of the vaporizer 1.

[0092] For example, the connection channel 64 can be connected to the body 2 of the aerosol generating device 1000. Aerosols discharged to the outside of the containing unit 50 through the outlet 57 can be moved to the body 2 of the aerosol generating device 1000 through the connection channel 64 and discharged to the outside of the aerosol generating device 1000 along the airflow channel formed in the body 2.

[0093] The cover 60 may include a connection terminal 66 for electrically connecting the vaporizer 1 to the body 2. For example, the connection terminal 66 may be connected to the heating element 40 to regulate the connection between the heating element 40 and the battery and processor in the body 2. Thus, the heating element 40 may be battery powered and controlled by the processor.

[0094] Figure 3A This is a perspective view of the housing unit of the vaporizer according to an embodiment. Figure 3B for Figure 3A The side view of the accommodating unit shown, and Figure 3C for Figure 3A The plan view of the accommodating unit is shown.

[0095] refer to Figures 3A to 3C The vaporizer housing unit 50a according to the embodiment may include a storage recess 51a, a support recess 52, a central space 53, an inlet 56, and an outlet 57. In this case, the core 30 and the heating element 40 may be located in the housing space of the housing unit 50a (i.e., the storage recess 51a, the support recess 52, and the central space 53).

[0096] like Figures 3A to 3C As shown, the heating element 40 can be configured to surround the outer peripheral surface of the core 30 housed in the housing unit 50a, but the arrangement of the heating element 40 is not limited to this.

[0097] For example, the heating element 40 may be plate-shaped and disposed near at least a portion of the core 30 housed in the housing unit 50a to heat the core 30. As another example, the heating element 40 may be a porous heater (e.g., a ceramic heater) integrally formed with the core 30.

[0098] The support groove 52 may have a specified length l in the longitudinal direction (e.g., the y-axis direction) of the core 30 to support at least a portion of the core 30, and the support groove 52 may have a width w in a direction intersecting the longitudinal direction of the core 30 (e.g., the x-axis direction) corresponding to the size (e.g., the diameter d) of the core 30. o Therefore, the inner surface of the support groove 52 can contact at least a portion of the outer peripheral surface of the core 30, thereby supporting the core 30.

[0099] Storage recess 51a can be a space for temporary storage or retention of aerosol-generating substances supplied from the storage unit. This can be achieved through a sealed unit (e.g., Figure 2A The opening formed in the sealing unit 20) (e.g. Figure 2A (Opening 22) Aerosol-generating material that has been removed from the storage unit can first be transferred to the storage recess 51a. Aerosol-generating material temporarily stored or retained in the storage recess 51a can permeate from the first end portion 31 and the second end portion 33 of the core 30 located in the storage recess 51a to the central portion 32 of the core 30.

[0100] In one embodiment, the receiving unit 50a may include a plurality of support grooves 52, which are formed to support the first end portion 31 and the second end portion 33 of the core 30 received in the receiving unit 50a. Furthermore, the receiving unit 50a may include a storage groove 51a that temporarily stores aerosol-generating material supplied from a storage unit and transfers the aerosol-generating material to the first end portion 31 and the second end portion 33 of the core 30 received in the receiving unit 50a.

[0101] For example, the support groove 52 may be located at a predetermined distance from the central space 53 forming a portion of the cavity of the receiving unit 50a in the longitudinal direction of the core 30. That is, the storage groove 51a may be located at a position farther from the central space 53 or the cavity than the support groove 52.

[0102] The core 30 can contact the inner surface of the support groove 52. For example, the dimension d of the core 30 and the width w of the support groove 52 are... o Within the fitting tolerance range, the core 30 can be fitted into the support groove 52.

[0103] The core 30, disposed in the receiving unit 50a, extends from the central space 53 of the receiving unit 50a to the end 52-1 of the supporting groove 52. The core 30 may extend beyond the end 52-1 of the supporting groove 52 into the interior of the storage groove 51a. At least a portion of the core 30 disposed in the receiving unit 50a may contact at least a portion of the inner surface of the storage groove 51a. Therefore, the core 30 disposed in the receiving unit 50a can increase the contact area with the aerosol-generating material retained in the storage groove 51a, thereby enabling the absorption of a larger amount of aerosol-generating material.

[0104] When the heating element 40 is located at the central portion 32 of the core 30, the aerosol-generating material supplied to the core 30 through both end portions of the core 30 must be conveyed to the central portion 32 of the core 30 so that the heating element 40 can generate aerosols. In other words, for aerosols to be successfully generated in the central portion 32 of the core 30, it is important that the aerosol-generating material is successfully supplied to the core 30 through both end portions of the core 30.

[0105] According to the implementation method, the maximum width W1 of the storage groove 51a can be greater than the maximum width w of the support groove 52. o In this case, the maximum width W1 can refer to the longest width of the storage groove 51a measured in a direction (e.g., the x-axis direction) that intersects the longitudinal direction of the core 30.

[0106] For example, the storage groove 51a may include a region extending from the first end portion 31 and the second end portion 33 of the core 30 in the longitudinal direction, and a region extending from the first end portion 31 and the second end portion 33 of the core 30 in the width direction (i.e., the direction intersecting the longitudinal direction of the core 30). In this case, the region extending in the width direction may extend from the first end portion 31 and the second end portion 33 of the core 30 in one or both directions along the width axis (i.e., the x-axis) of the core 30.

[0107] Since the storage groove 51a has a wider maximum width than the support groove 52, the storage groove 51a can retain more aerosol-generating material supplied from the storage unit, and the surface area of ​​the core 30 in contact with the aerosol-generating material retained in the storage groove 51a can be increased.

[0108] Therefore, the supply route for aerosol-generating substances can be expanded. The core 30 can absorb the aerosol-generating substances through the circumferential surfaces of the first end portion 31 and the second end portion 33, as well as through the side surfaces of the first end portion 31 and the second end portion 33. Therefore, the amount of aerosol-generating substances absorbed by the core 30 can be increased, thereby increasing the amount of aerosol generated by the vaporizer.

[0109] Figure 3D It is shown Figure 3A A view showing the state in which the accommodating unit 50a is in contact with the sealing unit.

[0110] refer to Figure 3D The sealing unit 20, having an opening 22 through which aerosol-generating substances can move, can contact or be connected to the containing unit 50a. In this case, the sealing unit 20 can contact the containing unit 50a while the sealing unit 20 is connected to the storage unit 10. However, for better understanding, the storage unit 10 is omitted.

[0111] In one embodiment, in order to move the aerosol-generating material stored in the storage unit into the storage recess 51a, when the storage unit and the receiving unit 50a are connected to each other, the opening 22 may be located in a position corresponding to the storage recess 51a.

[0112] For example, when the sealing unit 20 contacts the receiving unit 50a, the opening 22 can be positioned to form a moving channel 25 connected to the storage recess 51a. Therefore, the amount of aerosol-generating material leaking between the receiving unit 50a and the storage unit 10 and / or the sealing unit 20 can be reduced, and the aerosol-generating material can be efficiently supplied to the storage recess 51a.

[0113] As described above, the containing unit 50a may include an inlet 56 through which external air is introduced into the vaporizer. The external air introduced into the vaporizer can pass through a chamber (not shown) that generates aerosols and can be discharged to the outside of the vaporizer through an outlet 57. In this way, the airflow can be circulated inside the vaporizer.

[0114] When the aerosol-generating material stored in the storage unit 10 and / or storage groove 51a moves through the core 30 to the central space 53, a pressure difference can be generated between the central space 53 and the storage unit 10 and / or storage groove 51a.

[0115] A portion of the external air introduced into the cavity can flow back in the opposite direction (e.g., +y or -y direction) to the direction of movement of the aerosol-generating material from one end portion of the core 30 to the central portion of the core 30, thereby compensating for the pressure difference. Therefore, a portion of the external air can move into the storage recess 51a and / or opening 22, and bubbles can form in the storage recess 51a and / or opening 22.

[0116] Bubbles formed in opening 22 and / or storage recess 51a can narrow or close the movement channel 25 of the aerosol-generating material supplied from the storage unit to the storage recess 51a, and thus can inhibit the uniform supply of aerosol-generating material from the storage unit to the storage recess 51a. Therefore, the internal structure of the vaporizer can be configured to prevent the movement channel 25 of the aerosol-generating material from being blocked by bubbles.

[0117] according to Figure 3D In the illustrated embodiment, the size of the opening 22 can correspond to the size of the inlet side of the storage groove 51a supplying the aerosol-generating material. For example, the maximum width W1 of the storage groove 51a can be equal to or greater than the maximum width W2 of the opening 22. As another example, the ratio of the maximum width W1 of the storage groove 51a to the maximum width W2 of the opening 22 can approximately correspond to 1:0.8 to 1:1.2.

[0118] In this way, since the size of the opening 22 corresponds to the size of the inlet side of the storage groove 51a, the movement channel 25 through which the aerosol-generating material moves can be maximized, and thus the bottleneck effect caused by the size difference between the opening 22 and the storage groove 51a can be prevented. Furthermore, even if bubbles are generated in the storage groove 51a and / or the opening 22, the bubbles can be easily removed, thereby preventing blockage of the movement channel 25 through which the aerosol-generating material moves.

[0119] In one embodiment, the sealing unit 20 may also have an extending surface 23 that connects to the opening 22 and slopes toward the core 30. The aerosol-generating material may be in a liquid or gel state with high viscosity, thus there is a risk that the speed at which the aerosol-generating material passes through the narrow channel may be slowed, or that the narrow channel may be blocked by a membrane formed in the narrow channel. According to one embodiment, the aerosol-generating material stored in the storage unit 10 may enter the opening 22 along the extending surface 23 formed adjacent to the storage recess 51a, and thus easily move to the outside of the storage unit 10 (e.g., to the storage recess 51a).

[0120] refer to Figure 3DThe sealing unit 20 can contact the sealing unit 20 and the core 30 housed in the receiving unit 50a. Therefore, at least a portion of the core 30 can be surrounded by the sealing unit 20 and the receiving unit 50a. For example, the peripheral edges of the two end portions of the core 30 can contact the support groove 52 and a portion of the sealing unit 20, and thus, the two end portions of the core 30 can be surrounded by the support groove 52 and the sealing unit 20.

[0121] In an implementation, the sealing unit 20 may be located away from the storage unit (e.g., Figure 2A The support portion 24 protrudes in the direction (e.g., the -z direction) of the storage unit 10. The support portion 24 can be formed at a position facing the support groove 52 when the sealing unit 20 contacts the receiving unit 50a, and the support portion 24 can be inserted into the support groove 52.

[0122] The two end portions of the core 30 located between the receiving unit 50a and the sealing unit 20 can contact the support groove 52 and the support portion 24. That is, the lower portion of the end portion of the core 30 can be surrounded by the support groove 52, and the upper portion of the end portion of the core 30 can be inserted into and surrounded by the support portion 24 of the support groove 52.

[0123] Therefore, the gap 35 between the outer peripheral surface of the core 30 and the support groove 52 and / or support portion 24 can be reduced, thereby reducing leakage from the storage groove 51a to the central space 53.

[0124] Therefore, most of the aerosol-generating material retained in the storage groove 51a can be moved through the end portion of the core 30 to the central portion of the core 30, and the amount of aerosol-generating material leaking from the vaporizer can be reduced.

[0125] The position of the core 30 can be fixed by the sealing unit 20 and the receiving unit 50a. For example, the end portion of the core 30 located in the support groove 52 can be pressed by the support portion 24 and / or the support groove 52, thereby maintaining the position of the core 30.

[0126] Figure 4A This is a perspective view of the housing unit in a vaporizer according to another embodiment. Figure 4B yes Figure 4A The side view of the accommodating unit shown, and Figure 4C yes Figure 4A The plan view of the accommodating unit is shown.

[0127] refer to Figures 4A to 4C According to another embodiment, the housing unit 50b in the vaporizer may include having a... Figures 3A to 3CThe storage groove 51a of the accommodating unit 50a in the vaporizer shown has a different structure than the storage groove 51b.

[0128] refer to Figure 4C The storage recess 51b may include a first region 51b-1 and a second region 51b-2. The first region 51b-1 may be a region extending from the end portion 31 of the core 30 housed in the receiving unit 50b along the longitudinal direction (e.g., the y-axis direction) of the core 30. The second region 51b-2 may be a region extending from the end portion 31 of the core 30 along the width direction (e.g., the x-axis direction) of the core 30. The second region 51b-2 extending in the width direction of the core 30 may extend from the end portion 31 of the core 30 along two directions intersecting the longitudinal direction of the core 30 (e.g., the +x direction and the -x direction).

[0129] For example, the cross-section of the storage groove 51b formed by the intersection of the xz planes (i.e., the cross-section taken along the width direction intersecting the longitudinal direction of the core 30) can be approximately rectangular or trapezoidal. In this cross-section, the width W1 of the second region 51b-2 of the storage groove 51b can be greater than the width W1' of the first region 51b-1 of the storage groove 51b.

[0130] The width W1' of the first region 51b-1 of the storage groove 51b can be the same as the width w of the support groove 52. o Irrelevant.

[0131] Aerosol-generating substances retained in the first region 51b-1 of the storage groove 51b can be effectively absorbed into the core 30 through the side surface of the end portion 31 of the core 30. Aerosol-generating substances retained in the second region 51b-2 of the storage groove 51b can be effectively absorbed into the core 30 through the outer peripheral surface of the end portion 31 of the core 30.

[0132] Therefore, since the space of the storage groove 51b includes a region extending along both the longitudinal and width directions of the core 30, the amount of aerosol-generating material that can be retained by the storage groove 51b can be increased. Furthermore, the supply path through which the aerosol-generating material is absorbed into the core 30 can be extended.

[0133] Figure 5A This is a perspective view of the housing unit of a vaporizer according to another embodiment. Figure 5B for Figure 5A The side view of the accommodating unit shown, and Figure 5C for Figure 5A The plan view of the accommodating unit is shown.

[0134] refer to Figures 5A to 5C According to another embodiment, the vaporizer housing unit 50c may include having a... Figures 3A to 4C Storage groove 51a and storage groove 51b with different structures are shown in the vaporizer containing units 50a and 50b.

[0135] according to Figures 5A to 5C In the illustrated embodiment, the storage recess 51c may include: a first region extending from the end portion 31 of the core 30 along the longitudinal direction (e.g., the y-axis direction) of the core 30; and a second region extending from the end portion 31 of the core 30 along the width direction (e.g., the x-axis direction) of the core 30. The second region extending in the width direction of the core 30 may extend from one end portion 31 of the core 30 in one direction (e.g., the +x direction).

[0136] For example, refer to Figure 5B When viewed from a cross-section of the storage groove 51c formed by the intersection of the xz planes, the storage groove 51c may include a bottom surface 51c-1, a first sidewall surface 51c-2, and a second sidewall surface 51c-3.

[0137] The bottom surface 51c-1 and the first sidewall surface 51c-2 can contact at least a portion of the core 30. The second sidewall surface 51c-3 can be separated from the core 30 and the first sidewall surface 51c-2 in the width direction (i.e., the x-axis direction) of the core 30. In this case, the maximum width W1” of the storage groove 51c, that is, the longest distance between the first sidewall surface 51c-2 and the second sidewall surface 51c-3, can be greater than the maximum width w of the support groove 52. o .

[0138] The structure of the storage recess 51c can take into account the trade-off between the amount of aerosol generated material stored or retained and the amount of aerosol generated material leaking into the vaporizer during the design phase.

[0139] according to Figures 5A to 5C In the illustrated embodiment, the space within the storage groove 51c is expanded to a extent sufficient to supply a sufficient quantity of aerosol-generating material to the core 30. That is, the storage groove 51c is expanded only in one width direction (e.g., the +x direction), which to some extent expands the supply path of the aerosol-generating material while reducing leakage.

[0140] Figure 6A This is a perspective view of the housing unit in a vaporizer according to another embodiment. Figure 6B yes Figure 6A The side view of the accommodating unit shown, and Figure 6C yes Figure 6A The plan view of the accommodating unit is shown.

[0141] refer to Figures 6A to 6CAccording to another embodiment, the housing unit 50d in the vaporizer may include having a... Figures 3A to 5C Storage grooves 51a, 51b, and 51c of the accommodating units 50a, 50b, and 50c shown have storage grooves 51d with different structures.

[0142] According to another embodiment, the width of the storage recess 51d may decrease in a direction away from the storage cell (e.g., the -z direction). That is, the storage recess 51d may have a tapered shape with a wide inlet through which the aerosol-generating material is supplied, and the tapered shape narrows in a depth direction (e.g., the -z direction) of the storage recess 51d.

[0143] For example, refer to Figure 6B From the cross-section of the storage groove 51d formed by the intersection of the xz planes, the storage groove 51d may include a curved surface 51d-1 and an inclined surface 51d-2.

[0144] The curved surface 51d-1 may be a surface formed to contact the core 30 along the circumferential direction of the core 30. The inclined surface 51d-2 may be a surface formed to narrow the storage groove 51d in the depth direction of the storage groove 51d. In this case, the angle of the inclined surface 51d-2 can be designed differently according to different embodiments, and the volume of the space within the storage groove 51d can be changed according to the angle of the inclined surface 51d-2.

[0145] Because the storage recess 51d has a width that narrows toward the direction away from the storage unit, the possibility of leakage of aerosol-generating substances can be reduced.

[0146] Furthermore, the curved surface 51d-1 and / or inclined surface 51d-2 of the storage groove 51d can surround at least a portion of the core 30, so that aerosol-generating material supplied from the storage unit can be guided to the core 30 along the supply path formed by the inclined surface 51d-2. According to the above embodiment, the formation of dead space in which aerosol-generating material accumulates in the storage groove 51d can be minimized.

[0147] exist Figures 3A to 6C The structure of the core 30, heating element 40 and accommodating units 50a, 50b, 50c, 50d shown is merely an example and can be modified in various forms, with the support groove 52 and storage grooves 51a, 51b, 51c, 51d located in the accommodating unit.

[0148] For example, the heating element 40 can be positioned near the core 30, rather than wrapped around it. The core 30 can have a mesh or plate shape instead of an elongated shape. Furthermore, the position and number of storage recesses 51a, 52b, 52c, 52d, support recess 52, inlet 56, and outlet 57 in the accommodating units 50a, 50b, 50c, and 50d can be varied.

[0149] Figure 7 This is a view showing an example of inserting an aerosol generating article into an aerosol generating apparatus according to an embodiment, and Figure 8 This is a view showing an example of inserting an aerosol generating article into an aerosol generating apparatus according to another embodiment.

[0150] refer to Figure 7 and Figure 8 The aerosol generating apparatus 100 may include a battery 110, a controller 120, a heater 130, and a vaporizer 140. Furthermore, an aerosol generating article 200 may be inserted into the internal space of the aerosol generating apparatus 100. For example, Figure 8 The aerosol generating device 100 in the middle can be with Figure 1 The aerosol generating device 1000 is the same as that used in the aerosol generating device, and is applied to Figure 7 and Figure 8 The vaporizer 140 of the aerosol generating device 100 can be connected with Figure 2A It is the same as the vaporizer 1 in the middle.

[0151] Figure 7 and Figure 8 The aerosol generating apparatus 100 shown includes a vaporizer. However, the implementation is not limited to this method, and the vaporizer may be omitted. In the case where the vaporizer is omitted from the aerosol generating apparatus 100, the aerosol generating article 200 contains an aerosol generating substance such that when the aerosol generating article 200 is heated by the heater 130, the aerosol generating article 200 generates an aerosol.

[0152] Figure 7 and Figure 8 The components of the aerosol generating apparatus 100 related to this embodiment are shown. Therefore, those skilled in the art will understand that, in addition to... Figure 7 and Figure 8 In addition to the components shown, other general-purpose components may also be included in the aerosol generating apparatus 100.

[0153] in addition, Figure 7 and Figure 8 The aerosol generating apparatus 100 shown includes a heater 130. However, the heater 130 can be omitted if necessary.

[0154] Figure 7The battery 110, the controller 120, the carburetor 140, and the heater 130 are shown in series. Furthermore, Figure 8 The vaporizer 140 and the heater 130 are shown arranged in parallel. However, the internal structure of the aerosol generating device 100 is not limited to... Figure 7 or Figure 8 The structure shown. In other words, depending on the design of the aerosol generating device 100, the battery 110, the controller 120, the vaporizer 140, and the heater 130 can be arranged differently.

[0155] When the aerosol generating article 200 is inserted into the aerosol generating device 100, the aerosol generating device 100 can operate the vaporizer 140 to generate aerosol from the vaporizer 140. The aerosol generated by the vaporizer 140 is delivered to the user by passing through the aerosol generating article 200. The vaporizer 140 will be described in more detail later.

[0156] Battery 110 can supply power for the operation of aerosol generating apparatus 100. For example, battery 110 can supply power for heating heater 130 or vaporizer 140, and can supply power for operation controller 120. In addition, battery 110 can supply power for the operation of displays, sensors, motors, etc. installed in aerosol generating apparatus 100.

[0157] The controller 120 can control the overall operation of the aerosol generating device 100. Specifically, the controller 120 can control not only the operation of the battery 110, heater 130, and vaporizer 140, but also the operation of other components included in the aerosol generating device 100. Furthermore, the controller 120 can check the status of each component of the aerosol generating device 100 to determine whether the aerosol generating device 100 is capable of operation.

[0158] 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 memory, in which a program executable in the microprocessor is stored. Those skilled in the art will understand that the processor may be implemented in other forms of hardware.

[0159] The heater 130 can be heated by electricity supplied by the battery 110. For example, when the aerosol generating article 200 is inserted into the aerosol generating apparatus 100, the heater 130 can be located outside the aerosol generating article 200. Therefore, the heated heater 130 can increase the temperature of the aerosol generating substance in the aerosol generating article 200.

[0160] Heater 130 may include a resistance heater. For example, heater 130 may include a conductive rail, and heater 130 may be heated when current flows through the conductive rail. However, heater 130 is not limited to the example described above, 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 apparatus 100, or it may be set by the user.

[0161] As another example, heater 130 may include an induction heater. Specifically, heater 130 may include a conductive coil for heating an aerosol-generating article in an induction heating method, and the aerosol-generating article may include a base that can be heated by the induction heater.

[0162] Figure 7 and Figure 8 The heater 130 is shown positioned outside the aerosol generating article 200, but the position of the heater 130 is not limited thereto. For example, the heater 130 may include a tubular heating element, a plate heating element, a needle-shaped heating element, or a rod-shaped heating element, and may heat the interior or exterior of the aerosol generating article 200 depending on the shape of the heating element.

[0163] Furthermore, the aerosol generating apparatus 100 may include a plurality of heaters 130. Here, the plurality of heaters 130 may be inserted into the aerosol generating article 200 or may be arranged outside the aerosol generating article 200. Additionally, some of the heaters 130 may be inserted into the aerosol generating article 200, while others may be arranged outside the aerosol generating article 200. Furthermore, the shape of the heaters 130 is not limited to... Figure 7 and Figure 8 The shapes shown are not limited to those shown in the original text, but can include a variety of shapes.

[0164] The vaporizer 140 can generate an aerosol by heating a 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 140 can move along an airflow channel of the aerosol generating device 100, and the airflow channel can be configured such that the aerosol generated by the vaporizer 140 is delivered to the user through the aerosol generating article 200.

[0165] For example, the vaporizer 140 may include a liquid storage unit, a liquid delivery element, and a heating element, but is not limited thereto. For example, the liquid storage unit, liquid delivery element, and heating element may be included as independent modules in the aerosol generating apparatus 100. The liquid storage unit, liquid delivery element, and heating element may be integrated with... Figure 2AThe vaporizer 1 shown includes the same storage unit 10, core 30, and heating element 40.

[0166] The liquid storage unit can store the liquid composition. For example, the liquid composition may be a liquid containing tobacco substances having volatile tobacco aroma components, or a liquid containing non-tobacco substances. The liquid storage unit may be detachable from the vaporizer 140, or may be integrally formed with the vaporizer 140.

[0167] For example, the liquid composition may include water, solvent, ethanol, plant extracts, fragrances, flavorings, or vitamin mixtures. The fragrance may include, but is not limited to, menthol, peppermint oil, spearmint oil, and various fruity flavorings. Flavorings may include ingredients capable of providing a variety of scents or flavors to the user. The vitamin mixture may be, but is not limited to, a mixture of at least one of vitamins A, B, C, and E. Furthermore, the liquid composition may include an aerosol-forming matrix such as glycerin and propylene glycol.

[0168] The liquid delivery element can deliver the liquid composition in the liquid storage section to the 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.

[0169] The heating element is an element that heats the liquid composition conveyed by the liquid delivery element. For example, the 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 a conductive wire, such as a nichrome wire, and may be positioned to be wound around the liquid delivery element. The heating element can be heated by a current supply and can transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. Therefore, an aerosol can be generated.

[0170] For example, vaporizer 140 can be called a cartridge or atomizer, but is not limited to that.

[0171] In addition to the battery 110, controller 120, heater 130, and vaporizer 140, 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 such that even when the aerosol generating article 200 is inserted into the aerosol generating apparatus 100, external air can be introduced or internal air can be exhausted.

[0172] Although not in Figure 7 and Figure 8 As shown, 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, when the bracket and the aerosol generating device 100 are connected to each other, the heater 130 can be heated.

[0173] The aerosol generating article 200 can be similar to a conventional combustible cigarette. For example, the aerosol generating article 200 can be divided into a first part including aerosol generating material and a second part including a filter, etc. Alternatively, the second part of the aerosol generating article 200 may also include aerosol generating material. For example, aerosol generating material made in the form of particles or capsules can be inserted into the second part.

[0174] The first part can be fully inserted into the aerosol generating device 100, and 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 100. The user can inhale the aerosol while holding the second part in their mouth. In this case, the aerosol is generated by outside air passing through the first part, and the generated aerosol passes through the second part and is delivered to the user's mouth.

[0175] For example, outside air can flow into at least one air passage formed in the aerosol generating apparatus 100. For example, the opening and closing and / or size of the air passage formed in the aerosol generating apparatus 100 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 on the surface of the aerosol generating article 200.

[0176] Figure 9 An example of an aerosol-generated article is shown.

[0177] Figure 9 This is a diagram showing an example of an aerosol-generated article.

[0178] refer to Figure 9 The aerosol-generating article 200 includes a tobacco stick 210 and a filter stick 220. (See above for reference.) Figure 7 and Figure 8 The first part mentioned may include tobacco stick 210, while the second part may include filter stick 220.

[0179] Figure 9The filter rod 220 is shown to include a single segment, but is limited thereto. 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 some component included in the aerosol. Furthermore, if necessary, the filter rod 220 may also include at least one segment configured to perform other functions.

[0180] 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.

[0181] 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, wetting agents, and / or organic acids. Additionally, the tobacco stick 210 may include flavoring liquids, such as menthol or wetting agents, which are injected into the tobacco stick 210.

[0182] The tobacco stick 210 can be manufactured in various forms. For example, the tobacco stick 210 can be formed into a sheet or a strand. Furthermore, the tobacco stick 210 can be formed into pipe tobacco, which is formed from tiny fragments cut from tobacco sheets. Additionally, the tobacco stick 210 can be surrounded by a heat-conducting material. For example, the heat-conducting material can be, but is not limited to, metal foil, such as aluminum foil. For example, the heat-conducting material surrounding the tobacco stick 210 can evenly distribute the heat transferred to the tobacco stick 210, and thus can increase the thermal conductivity applied to the tobacco stick and improve the taste of the tobacco. Furthermore, the heat-conducting material surrounding the tobacco stick 210 can serve as a base heated by an induction heater. Here, although not shown in the figures, in addition to the heat-conducting material surrounding the tobacco stick 210, the tobacco stick 210 may also include an additional base.

[0183] The filter rod 220 may include a cellulose acetate filter. The shape of the filter rod 220 is not limited. For example, the filter rod 220 may include a cylindrical or tubular rod with a hollow interior. Furthermore, the filter rod 220 may include a recessed rod. When the filter rod 220 includes multiple segments, at least one of the multiple segments may have a different shape.

[0184] The filter rod 220 can be configured to produce fragrance. For example, a fragrance liquid can be injected into the filter rod 220, or additional fibers coated with a fragrance liquid can be inserted into the filter rod 220.

[0185] Furthermore, the filter rod 220 may include at least one capsule 230. Here, the capsule 230 may generate a fragrance or aerosol. For example, the capsule 230 may have a structure in which a liquid containing a fragrance material is encapsulated by a membrane. For example, the capsule 230 may have a spherical or cylindrical shape, but is not limited thereto.

[0186] When the filter rod 220 includes a section configured to cool the aerosol, the cooling section may comprise a polymeric material or a biodegradable polymeric material. For example, the cooling section may comprise only pure polylactic acid, but the material used to form the cooling section is not limited thereto. In some embodiments, the cooling section may comprise a cellulose acetate filter having multiple pores. However, the cooling section is not limited to the embodiments described above, and is not limited as long as the cooling section can cool the aerosol.

[0187] One or more implementations may also be implemented in the form of a recording medium, which includes computer-executable instructions, such as computer-executable program modules. A computer-readable medium can be any available medium accessible to a computer, and includes volatile and non-volatile media, as well as removable and non-removable media. Additionally, a computer-readable medium can include computer storage media and communication media. Computer storage includes removable and non-removable media, as well as volatile and non-volatile media, implemented in any method or technique for storing information such as computer-readable instructions, data structures, program modules, or other data.
