The aerosol-generating system comprises an aerosol-generating article 100 and an aerosol-generating device 200. The aerosol-generating article 100 is detachably mounted on the aerosol-generating device 200. The aerosol-generating device 200 is configured to heat the aerosol-generating article 100 to generate an aerosol for inhalation by a user.

[0083] As shown in FIG. 2 to FIG. 4 , in this embodiment, the aerosol generating article 100 may be columnar in shape as a whole, specifically, cylindrical in shape.

[0084] In this embodiment, the aerosol-generating article 100 includes a substrate segment 1010 and a first inner conductor 102. The substrate segment 1010 can be generally columnar, specifically cylindrical, and is filled with an aerosol-generating substrate 1012. In this embodiment, the substrate segment 1010 has a first end 101a and a second end 101b axially disposed opposite the first end 101a. The aerosol-generating substrate 1012 can generate an aerosol for inhalation by a user when heated. The first inner conductor 102 is at least partially embedded within the aerosol-generating substrate 1012 and, when connected to microwaves, radiates microwaves toward the aerosol-generating substrate 1012, thereby heating the aerosol-generating substrate 1012.

[0085] The aerosol-generating article 100 also includes an outer packaging structure 1011 and a functional segment connected to the substrate segment 1010. The functional segment may include a filter segment 1013 and a cooling segment 1014. The outer packaging structure 1011 may be made of paper material and may be coated around the aerosol-generating substrate 1012 and the outer periphery of the functional segment. The first end 101a of the substrate segment 1010 may be connected to the functional segment. Specifically, it may be connected to the cooling segment 1014 and coaxially spaced from the filter segment 1013. The cooling segment 1014 is formed by a gap between the substrate segment 1010 and the filter segment 1013. The aerosol-generating substrate 1012 may be a solid material in the form of strands, granules, columns, or sheets made from plant leaves, flowers, and / or stems. A fragrance component may be further added to the solid material. The filter segment 1013 may be a columnar filter. The first end 101a and the second end 101b may serve as the axial ends of the outer packaging structure 1011. In other embodiments, the filter section 1013 and the cooling section 1014 may be omitted. In other embodiments, the outer packaging structure 1011 is not limited to paper. In other embodiments, a support section (not shown) may be included between the cooling section 1014 and the aerosol-generating substrate 1012.

[0086] As shown in Figures 4 and 5 , the first inner conductor 102 is at least partially embedded in the aerosol-generating substrate 1012. Specifically, at least a portion of the first inner conductor 102 may extend from the second end 101b toward the first end 101a. The first inner conductor 102 may be coaxial with the aerosol-generating substrate 1012. Of course, it is understood that in other embodiments, the central axis of the first inner conductor 102 may be offset from the central axis of the aerosol-generating substrate 1012.

[0087] In this embodiment, the first inner conductor 102 includes an embedded portion 1021. The embedded portion 1021 may be cylindrical. Specifically, the embedded portion 1021 may be a solid or hollow cylindrical body with a pointed tip. Its cross-section may be generally circular, with a diameter smaller than the diameter of the matrix segment 1010 formed by the aerosol-generating substrate 1012, and the axial length of the embedded portion 1021 may be smaller than the axial length of the matrix segment 1010. The embedded portion 1021 may be integrally embedded in the aerosol-generating substrate 1012 and may be coaxially disposed with the matrix segment 1010 formed by the aerosol-generating substrate 1012 to radiate microwaves. The embedded portion 1021 may be made of a conductive metallic material.

[0088] In this embodiment, the first inner conductor 102 further includes a connecting portion 1022, which can be disposed at an end of the embedded portion 1021 away from the first end portion 101a and electrically connected to the embedded portion 1021. The connecting portion 1022 can be used to mechanically connect the aerosol generating article 100 to the aerosol generating device 200, and can also be used to electrically connect the embedded portion 1021 to the aerosol generating device 200, and can also conduct microwaves to the embedded portion 1021.

[0089] In this embodiment, the connection portion 1022 is at least partially exposed outside the aerosol-generating substrate 1012. Specifically, the connection portion 1022 is located at the second end portion 101b of the aerosol-generating article 100 and may be entirely exposed outside the second end portion 101b. Of course, it is understood that in other embodiments, the connection portion 1022 may be flush with the second end portion 101b, may be partially located within the aerosol-generating substrate 1012, or may be entirely disposed within the aerosol-generating substrate 1012 and partially exposed.

[0090] In this embodiment, the connecting portion 1022 may be generally sheet-shaped, specifically, circular. Of course, it is understood that in other embodiments, the connecting portion 1022 may not be limited to a sheet-shaped form, and may be, for example, annular or cylindrical. The diameter of the connecting portion 1022 may be comparable to the diameter of the matrix segment 1010. The connecting portion 1022 may be coaxially arranged with the embedded portion 1021. In other embodiments, the diameter of the connecting portion 1022 may be smaller or larger than the diameter of the matrix segment 1010.

[0091] In this embodiment, the connecting portion 1022 can be a separate structure from the embedding portion 1021, and the two can be detachably connected. Specifically, the connecting portion 1022 can be a first magnetic structure, one side of which can be attached to the end face of the embedding portion 1021, and the other side can be magnetically fixed to the aerosol generating device 200. Furthermore, the connecting portion 1022 can be a magnetic and conductive metal sheet, such as a stainless steel sheet.

[0092] In other embodiments, the connecting portion 1022 may be integrally formed with the embedded portion 1021. Specifically, the connecting portion 1022 and the embedded portion 1021 may be integrally formed by casting, pouring, or 3D printing. In other embodiments, the connecting portion 1022 may also be the end surface of the embedded portion 1021 located away from the first end 101a. In other embodiments, the connecting portion 1022 and the embedded portion 1021 are coaxial and of equal diameter, and are made of the same material.

[0093] In this embodiment, the aerosol-generating device may include a housing 30 and a microwave heating assembly 10. A mounting space is formed within the housing 30 for accommodating the microwave heating assembly 10. The microwave heating assembly 10 heats the aerosol-generating article 100 by introducing microwaves into a first inner conductor 102, which then radiates the microwaves.

[0094] As shown in Figures 6 and 7, in this embodiment, the microwave heating assembly 10 includes an outer conductor 11 and a second inner conductor 12. The outer conductor 11 defines a resonant cavity 14, which can be used to feed microwaves. The second inner conductor 12 is at least partially disposed within the resonant cavity 14 and is coaxially arranged with the resonant cavity 14. By disposing the second inner conductor 12, microwaves are transmitted from the second inner conductor 12 to the first inner conductor 102, which then radiates the microwaves to heat the aerosol-generating article 100.

[0095] In this embodiment, the outer conductor 11 is made of metal or other highly conductive materials, and may include a cylinder 111 and a resonant cavity cover 112. The resonant cavity cover 112 is sleeved on the cylinder 111 and can be detachably assembled with the cylinder 111.

[0096] In some embodiments, the cross-section of the barrel 111 can be substantially circular. Of course, it is understood that in other embodiments, the cross-section of the barrel 111 is not limited to circular and can be square or other shapes. The barrel 111 has an outer annular wall 1110, one end of which is provided with an opening 1111, and the other end is provided with a first end wall 1112, the opening 1111 being disposed opposite the first end wall 1112.

[0097] The resonant cavity cover 112 can be arranged to cover the opening 1111. The resonant cavity cover 112 can be connected and fixed to the cylinder 111 through a screw structure. In some embodiments, the resonant cavity cover 112 may include an integrally formed covering portion 112a and a protruding portion 112b; wherein the covering portion 112a can be sleeved on the cylinder 111 and is roughly in the shape of a hollow column. The covering portion 112a includes a second end wall 1121 and an annular side wall 1122; the second end wall 1121 covers the opening 1111 and is arranged opposite to the first end wall 1112; the annular side wall 1122 is connected to the second end wall 1121 and can be located on the outer periphery of the cylinder 111, and can be screwed to the cylinder 111. The protruding portion 112b is arranged on the second end wall 1121 and protrudes along the axial direction of the covering portion 112a in a direction away from the resonant cavity 14. In some embodiments, the convex portion 112 b may be cylindrical and have two through-holes, and an installation channel 1120 for installing the aerosol generating article 100 may be formed inside. The installation channel 1120 is coaxially arranged with the resonant cavity 14 .

[0098] As shown in Figures 7 to 9, in this embodiment, the second inner conductor 12 is at least partially disposed in the resonant cavity 14, is coaxially disposed with the resonant cavity 14, and is connected to the first end wall 1112. The second inner conductor 12 can be configured to be detachably connected to the aerosol-generating article 100 of the present invention, and when the aerosol-generating article 100 is connected, it is connected to the first inner conductor 102 of the aerosol-generating article 100 to achieve electrical conduction.

[0099] In this embodiment, the second inner conductor 12 may be cylindrical and have a roughly circular cross-section. In other embodiments, the cross-section of the second inner conductor 12 is not limited to a circular shape. For example, in other embodiments, the cross-section of the second inner conductor 12 may be square or elliptical. The outer diameter of the second inner conductor 12 is smaller than the inner diameter of the cylindrical body 111. The second inner conductor 12 may be made of a metal material or other highly conductive material, such as aluminum or a copper alloy. The second inner conductor 12 has a first end 12a and a second end 12b in its axial direction. The first end 12a and the second end 12b are disposed opposite each other, and the second end 12b may be connected to the first end wall 1112.

[0100] In this embodiment, the second inner conductor 12 may include a first column 121 and a second column 122. The first column 121 is positioned within the cylindrical body 111. The second column 122 is connected to one end of the first column 121 and is integrally formed with the first column 121. In some embodiments, the second column 122 may be disposed protruding from the first end wall 1112 of the cylindrical body 111. The radial dimension of the second column 122 is smaller than the radial dimension of the first column 121. The second inner conductor 12 is connected to the outer conductor 11. Specifically, the end surfaces where the first column 121 and the second column 122 meet may be connected to the first end wall 1112, thereby achieving a connection between the second column 122 and the first end wall 1112. The first end 12a is formed at the end of the first column 121 away from the second column 122. The second end 12b is formed at the end of the second column 122 away from the first column 121.

[0101] In this embodiment, a mounting groove 123 may be provided in a section of the second inner conductor 12 near the first end 12a. The depth of the mounting groove 123 is less than the axial length of the second inner conductor 12. The opening of the mounting groove 123 is located at the first end 12a. In this embodiment, the mounting groove 123 may be generally annular and may be coaxially disposed with the second inner conductor 12.

[0102] In this embodiment, the second inner conductor 12 is provided with a central through hole 124 at its center axis, and the central through hole 124 may extend from the second end 12b to the first end 12a along the center axis of the second inner conductor 12. In some embodiments, the central through hole 124 may be omitted.

[0103] In this embodiment, the microwave heating assembly 10 further includes a connecting structure 13. The connecting structure 13 is disposed on the second inner conductor 12, at least partially located at the first end 12a. The connecting structure 13 and the second inner conductor 12 are separate structures. In this embodiment, the connecting structure 13 can be generally annular in shape, embedded and installed in the second inner conductor 12 from the first end 12a, with one end surface flush with the second inner conductor 12. Specifically, the connecting structure 13 can be installed in the mounting groove 123, with one end surface flush with the end surface where the groove is located. In this embodiment, the connecting structure 13 can be a ring-shaped magnet. Of course, it is understood that in other embodiments, the connecting structure 13 is not limited to a ring-shaped magnet and can be made of a magnetically attracted metal material. Furthermore, the connecting structure 13 can also be a magnet of other shapes or a magnetically attracted metal, regardless of shape, to generate an attractive force on the first inner conductor 102, ensuring stable and reliable electrical conductivity between the first inner conductor 102 and the second inner conductor 12. In addition, magnetic attraction is formed between the connecting structure 13 and the connecting portion 1022 , and one of them can be set as a magnet, and the other can be set as a metal to be attracted by the magnet. Of course, both can be set as magnets.

[0104] In this embodiment, the provision of the connection structure 13 facilitates the removable connection and fixation of the aerosol-generating article 100 within the aerosol-generating device 200, and also facilitates the removable connection and fixation of the second inner conductor 12 to the first inner conductor 102. Before inhalation, the aerosol-generating article 100 with the first inner conductor 102 can be inserted through the mounting channel 1120. The connection portion 1022 between the portion of the aerosol-generating substrate 1012 located in the heating zone 141 and the first inner conductor 102 is attracted to the connection structure 13, thereby achieving electrical continuity between the first and second inner conductors 102, 12. When the inhalation is complete, the user can remove the aerosol-generating article 100 from the mounting channel 1120, and the first inner conductor 102 can be replaced along with the aerosol-generating article 100. In other embodiments, the connection between the first and second inner conductors 102, 12 is not limited to a second magnetic structure. In other embodiments, the connection structure 13 may also be a second plug-in card structure or other structure.

[0105] In some other embodiments, the connection structure 13 may be a non-independent structural component, and the second inner conductor 12 is directly and detachably mechanically and / or electrically connected to the connection portion 1022. For example, the aerosol generating product 100 can be directly placed on the first end 12a of the second inner conductor 12, and the connection structure 13 can be a contact surface provided at the first end 12a that is connected to the connection portion 1022 and is electrically conductive.

[0106] In this embodiment, the resonant cavity 14 is defined by at least the first end wall 1112, the second end wall 1121, the inner wall of the cylindrical body 111, and the outer wall of the first columnar body 121. Within the resonant cavity 14, a gap is provided between the first end 12a of the second inner conductor 12 and the second end wall 1121. This gap forms a heating zone 141. When microwaves are fed into the resonant cavity 14, energy is transferred to the heating zone 141, thereby heating at least a portion of the aerosol-generating article 100 disposed within the heating zone 141.

[0107] In this embodiment, the aerosol-generating article 100 may further include an airflow channel (not shown). Specifically, the connecting portion 1022 may be provided with airflow holes to form a portion of the airflow channel (not shown). The airflow holes may communicate with the aerosol-generating substrate 1012, allowing external airflow to enter the aerosol-generating article 100 and carry away the aerosol generated by the aerosol-generating substrate 1012. In other embodiments, the airflow channel (not shown) may not be limited to being provided on the connecting portion 1022, but may also be located on the periphery of the connecting portion 1022. Specifically, the cross-sectional dimensions of the connecting portion 1022 may be smaller than the end surface dimensions of the second end portion 101b. The airflow channel (not shown) may be defined by a portion of the outer peripheral wall of the connecting portion 1022 and the portion of the second end portion 101b not covered by the connecting portion 1022.

[0108] In this embodiment, the aerosol-generating device further includes a microwave feeding structure 20, which can be an SMA coaxial connector. The microwave feeding structure 20 can be mounted on the first end wall 1112 of the cylindrical body 111, communicates with the resonant cavity 14, and can be connected to a microwave source (not shown), thereby feeding microwaves into the resonant cavity 14. The microwave source (not shown) generates microwaves, which are fed through the microwave feeding structure 20, forming an antenna at the feeding location. This in turn generates an alternating electric field, transmitting energy upward along the closed conductor formed by the second inner conductor 12 and the resonant cavity 14 to the heating zone 141. This creates a "micro-antenna" effect at the end surface of the first end 12a of the second inner conductor 12 and the outer wall of the first inner conductor 102, generating a micro-electric field that draws energy from the periphery to the center, thereby heating the aerosol-generating substrate. Specifically, the microwave source (not shown) can have an output frequency of 2.45 GHz.

[0109] In this embodiment, the aerosol generating device may further include a power supply structure 40. A microwave source (not shown) and the power supply structure 40 may be disposed within the housing 30. The microwave source (not shown) may be connected to the microwave feeding structure 20, and the microwaves generated by the microwave source may be fed into the resonant cavity 14 through the microwave feeding structure 20. The power supply structure 40 may be connected to the microwave source (not shown) to supply power to the microwave source (not shown).

[0110] In this embodiment, the aerosol-generating system further includes a temperature measuring element 300. The temperature measuring element 300 may be at least partially disposed within the second inner conductor 12 and at least partially protrude beyond the first end 12a of the second inner conductor 12. In this embodiment, the temperature measuring element 300 may be longitudinally disposed and mounted within the central through-hole 124 of the second inner conductor 12. A detection end of the temperature measuring element 300 may protrude beyond the first end 12a and be located on the side of the connecting portion 1022 opposite the aerosol-generating article 100. The other end of the temperature measuring element 300 may be connected to a lead wire that extends outward from the second inner conductor 12 and connects to a temperature measurement circuit on the aerosol-generating device. The temperature measuring element 300 may extend axially along the second inner conductor 12, passing through the interior of the second inner conductor to measure the heating temperature of the aerosol-generating article 100. This facilitates real-time adjustment of the microwave energy fed into the aerosol-generating article 100 to ensure that the aerosol-generating article 100 is heated thoroughly without being burnt. In this embodiment, the temperature measuring element 300 may be a thermocouple. Of course, it is understood that in other embodiments, the temperature measuring element 300 is not limited to being a thermocouple and may also be a temperature measuring film. In other embodiments, the temperature measuring element 300 may be disposed solely on the end surface of the first end 12a of the second inner conductor 12. In other embodiments, the temperature measuring element 300 is not limited to being disposed on the second inner conductor 12 and may also be disposed on the first inner conductor 102. In other embodiments, the temperature measuring film may be disposed on the end surface of the first end 12a of the second inner conductor 12, with the electrical lead passing through the interior of the second inner conductor 12. Alternatively, the temperature measuring film may be disposed on the end surface of the connecting portion 1022, such that when the aerosol-generating article 100 is inserted, the temperature measuring film contacts and conducts electricity with the electrical lead.

This embodiment differs from the second embodiment in that the first inner conductor 102 is hollow, with a through hole 1023 formed inside the first inner conductor 102, which communicates with the outside. A temperature measuring element 300 can extend from the first end 12a of the second inner conductor 12 and be inserted into the through hole 1023 of the first inner conductor 102.

This embodiment differs from the second embodiment in that a connecting portion 1022 may be located at the second end portion 101 b. Specifically, the connecting structure 13 may include a receiving groove 125 disposed on the first end 12 a. The aerosol-generating article 100 may be partially received in the receiving groove 125, and the connecting portion 1022 may be received in the receiving groove 125 and in contact and electrical communication with the walls of the receiving groove 125. The cross-sectional dimensions of the receiving groove 125 may gradually increase toward the first end 12 a, with its minimum dimension adapted to match the outer diameter of the connecting portion 1022. This allows the connecting portion 1022 to be securely fixed to the receiving groove 125 through an interference fit, thereby ensuring stable and reliable electrical contact. It is understandable that the connection portion 1022 is electrically connected to the groove wall of the accommodating groove 125, and can be electrically connected to the peripheral wall of the accommodating groove 125, or to the bottom wall of the accommodating groove 125, or both the peripheral wall and the bottom wall of the accommodating groove 125 are electrically connected.

[0119] Specifically, the diameter of the connecting portion 1022 is smaller than the diameter of the matrix segment 1010, and the end surface of the connecting portion 1022 can be flush with the second end portion 101b, forming a plug-in portion for plugging with the connecting structure 13. The outer sidewall of the connecting portion 1022 can be provided with a latching protrusion 1024, which can protrude radially outward from the connecting portion 1022 and can be used for latching with the connecting structure 13.

[0120] In this embodiment, the connecting structure 13 and the second inner conductor 12 may be integrally formed and may include a boss 131 protruding from the first end 12a of the second inner conductor 12. The boss 131 is insertable into the aerosol-generating article 100. A slot 1311 is formed on the inner side of the boss 131, into which the connecting portion 1022 is inserted. A snap-fitting groove 132 is provided on the inner sidewall of the boss 131, which is adapted to engage with the snap-fitting protrusion 1024. The connection portion 1022 and the connecting structure 13 cooperate to ensure reliable and stable electrical contact.

[0121] In some other embodiments, the connecting portion 1022 may be provided to protrude from the second end portion 101 b , and the slot 1311 may be directly opened on the first end 12 a of the second inner conductor 12 and may be plugged with the connecting portion 1022 .

[0122] In some other embodiments, the connecting portion 1022 and the connecting structure 13 may not only be mutually compatible card insertion structures, but also be mutually compatible magnetic attraction structures.

[0123] It is understandable that the above embodiments only express the preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention.
