[0082] Figure 1 The first embodiment of the aerosol generating system of the present invention is shown. The aerosol generating system comprises an aerosol generating article 100 and an aerosol generating device 200; the aerosol generating article 100 can be detachably assembled on the aerosol generating device 200. The aerosol generating device 200 is used to heat the aerosol generating article 100 to generate aerosol for the user to inhale.

[0083] like Figures 2 to 4 As shown, in this embodiment, the aerosol generating article 100 can be columnar as a whole, specifically, it can be cylindrical.

[0084] In this embodiment, the aerosol generating article 100 includes a substrate segment 1010 and a first inner conductor 102. The substrate segment 1010 may be substantially 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 in its axial direction; the second end 101b is arranged opposite to the first end 101a. The aerosol generating substrate 1012 may generate an aerosol for the user to inhale in a heated state. The first inner conductor 102 is at least partially built into the aerosol generating substrate 1012, and may radiate microwaves to the aerosol generating substrate 1012 when microwaves are connected, thereby heating the aerosol generating substrate 1012.

[0085] The aerosol-generating article 100 further includes an outer wrapping structure 1011 and a functional section connected to the substrate section 1010. The functional section may include a filter section 1013 and a cooling section 1014. The outer wrapping structure 1011 may be made of paper material, which may wrap around the outer periphery of the aerosol-generating substrate 1012 and the functional section. The first end 101a of the substrate section 1010 may be connected to the functional section. Specifically, it may be connected to the cooling section 1014 and be coaxially and spaced apart from the filter section 1013. The cooling section 1014 is formed by the space between the substrate section 1010 and the filter section 1013. The aerosol-generating substrate 1012 may be a solid material in the form of filaments, granules, columns or flakes made of leaves, flowers and / or stems of plants, and fragrance components may be further added to the solid material. The filter section 1013 may be a columnar filter cotton. The first end 101a and the second end 101b may be the two axial ends of the outer wrapping structure 1011. In some other embodiments, the filter section 1013 and the cooling section 1014 may be omitted. In some other embodiments, the outer wrapping structure 1011 is not limited to being made of paper material. In some other embodiments, a support section (not shown in the figure) may further be included between the cooling section 1014 and the aerosol-generating substrate 1012.

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

[0087] In this embodiment, the first inner conductor 102 includes an embedding portion 1021. The embedding portion 1021 may be columnar. Specifically, the embedding portion 1021 may be a columnar body with a tip and being solid or hollow. Its cross-section may be generally circular, its diameter is smaller than the diameter of the substrate section 1010 formed by the aerosol-generating substrate 1012, and the axial length of the embedding portion 1021 is smaller than the axial length of the substrate section 1010. The embedding portion 1021 may be integrally embedded in the aerosol-generating substrate 1012, and may be coaxially arranged with the substrate section 1010 formed by the aerosol-generating substrate 1012 for radiating microwaves. The embedding portion 1021 may be made of a metal conductive material.

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

[0089] In this embodiment, at least a part of the connecting portion 1022 is exposed outside the aerosol-generating matrix 1012. Specifically, the connecting portion 1022 is located at the second end portion 101b of the aerosol-generating article 100 and can be integrally exposed outside the second end portion 101b. Of course, it can be understood that in some other embodiments, the connecting portion 1022 can be flush with the second end portion 101b, or partially located in the aerosol-generating matrix 1012, or integrally disposed in the aerosol-generating matrix 1012 and partially exposed.

[0090] In this embodiment, the connecting portion 1022 can be generally sheet-shaped, specifically, it can be a circular sheet. Of course, it can be understood that in some other embodiments, the connecting portion 1022 is not limited to being sheet-shaped, such as annular, columnar, etc. The diameter of the connecting portion 1022 can be equivalent to the diameter of the matrix section 1010. The connecting portion 1022 can be coaxially arranged with the embedding portion 1021. In some other embodiments, the diameter of the connecting portion 1022 can also be smaller or larger than the diameter of the matrix section 1010.

[0091] In this embodiment, the connecting portion 1022 and the embedding portion 1021 can be a split structure, and the two are detachably connected. Specifically, the connecting portion 1022 can be a first magnetic attraction 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. Further, the connecting portion 1022 can be a metal sheet that can be magnetized and conduct electricity, such as a stainless steel sheet. In some other embodiments, the connecting portion 1022 can also be a permanent magnet. In some other embodiments, the connecting portion 1022 is not limited to being a first magnetic attraction structure, and it can also be a first card insertion structure. The bottom surface of the connecting portion 1022 can be a smooth plane, so as to ensure the reliability of the electrical contact at this place. The connecting portion 1022 can also at least partially wrap around the outer peripheral surface of the matrix section 1010.

[0092] In some other embodiments, the connecting portion 1022 and the embedding portion 1021 can be integrally formed. Specifically, the connecting portion 1022 and the embedding portion 1021 can be integrally formed by casting, pouring, or 3D printing. In some other embodiments, the connecting portion 1022 can also be the end face of the embedding portion 1021 away from the first end portion 101a. In some other embodiments, the connecting portion 1022 and the embedding portion 1021 are coaxial and have the same diameter, and the two 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.

By providing the second inner conductor 12, the second inner conductor 12 conducts microwaves to the first inner conductor 102, and the first inner conductor 102 radiates microwaves to heat the aerosol generating article 100.

[0095] In this embodiment, the outer conductor 11 is processed from a metal material or other highly conductive material, and may include a cylindrical body 111 and a resonant cavity cover 112. The resonant cavity cover 112 is sleeved on the cylindrical body 111 and is detachably assembled with the cylindrical body 111.

[0096] In some embodiments, the cross-section of the cylindrical body 111 may be generally circular. Of course, it can be understood that in some other embodiments, the cross-section of the cylindrical body 111 is not limited to being circular, and may be square or other shapes. The cylindrical body 111 has an outer ring 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 is disposed opposite to the first end wall 1112. In some embodiments, the cylindrical body 111 is formed by the outer ring wall 1110, that is, the two may be the same component.

[0097] The resonator cover 112 can be arranged to cover the opening 1111. The resonator cover 112 can be fixedly connected to the cylinder 111 through a screwing structure. In some embodiments, the resonator cover 112 can include an integrally formed covering portion 112a and a convex portion 112b; wherein the covering portion 112a can be sleeved on the cylinder 111 and is generally in a hollow column shape.

The second inner conductor 12 can be configured to be detachably connected to the aerosol generating article 100 of the present invention and is connected to the first inner conductor 102 of the aerosol generating article 100 when connected to the aerosol generating article 100 so as to achieve electrical conduction.

[0099] In this embodiment, the second inner conductor 12 can be in a columnar shape, and its cross-section can be generally circular. In some other embodiments, the cross-section of the second inner conductor 12 is not limited to being circular. For example, in some other embodiments, the cross-section of the second inner conductor 12 can be square or elliptical, etc. The outer diameter of the second inner conductor 12 is smaller than the inner diameter of the cylinder 111. The second inner conductor 12 can be made of a metal material or other highly conductive materials, such as aluminum, copper alloy, etc. 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 to each other, and the second end 12b can be connected to the first end wall 1112.

[0100] In this embodiment, the second inner conductor 12 may include a first columnar body 121 and a second columnar body 122. The first columnar body 121 is located in the cylindrical body 111. The second columnar body 122 is connected to one end of the first columnar body 121 and is integrally formed with the first columnar body 121. In some embodiments, the second columnar body 122 may penetrate through the first end wall 1112 of the cylindrical body 111. The radial dimension of the second columnar body 122 is smaller than the radial dimension of the first columnar body 121. The second inner conductor 12 is connected to the outer conductor 11. Specifically, the end face where the first columnar body 121 is in contact with the second columnar body 122 may be connected to the first end wall 1112, thereby realizing the connection between the second columnar body 122 and the first end wall 1112. The first end 12a is formed at one end of the first columnar body 121 away from the second columnar body 122. The second end 12b is formed at one end of the second columnar body 122 away from the first columnar body 121.

The depth of the installation groove 123 is smaller than the axial length of the second inner conductor 12. The notch of the installation groove 123 is located at the first end 12a. In this embodiment, the installation groove 123 may be generally annular and may be coaxially arranged with the second inner conductor 12.

[0102] In this embodiment, a central through hole 124 is provided at the central axis of the second inner conductor 12. The central through hole 124 may extend along the central axis direction of the second inner conductor 12 from the second end 12b to the first end 12a.

[0103] In this embodiment, the microwave heating assembly 10 further includes a connection structure 13. The connection structure 13 is provided on the second inner conductor 12 and at least part of it is located at the first end 12a. The connection structure 13 and the second inner conductor 12 are of a split structure. In this embodiment, the connection structure 13 may be generally annular. It may be embedded and installed in the second inner conductor 12 from the first end 12a, and one end face of it is flush with the second inner conductor 12. Specifically, the connection structure 13 may be installed in the installation groove 123, and one end face of it may be flush with the end face where the notch is located. In this embodiment, the connection structure 13 may be an annular magnet. Of course, it can be understood that in some other embodiments, the connection structure 13 is not limited to an annular magnet and may be a metal material that can be magnetically attracted. In addition, the connection structure 13 may also be other shaped magnets or metals that can be magnetically attracted, and the shape is not limited. It can form an attractive force on the first inner conductor 102 to ensure the stability and reliability of the electrical conduction performance between the first inner conductor 102 and the second inner conductor 12. In addition, a magnetic attraction is formed between the connection structure 13 and the connection portion 1022. Either one of them can be set as a magnet, and the other one can be set as a metal that can be magnetically attracted. Of course, both of them can be set as magnets.

[0104] In this embodiment, by providing the connection structure 13, it is convenient for the aerosol-generating article 100 to be detachably connected and fixed in the aerosol-generating device 200, and it is also convenient for the detachable connection and fixation of the second inner conductor 12 and the first inner conductor 102. Before suction, the aerosol-generating article 100 with the first inner conductor 102 can be inserted along the installation channel 1120. The aerosol-generating matrix 1012 is partially located in the heating area 141. The connection part 1022 between the first inner conductor 102 and the connection structure 13 is suctioned and combined so that the first inner conductor 102 and the second inner conductor 12 are electrically connected. When the suction is completed, the user can pull out the aerosol-generating article 100 from the installation channel 1120. The first inner conductor 102 can be replaced together with the aerosol-generating article 100. In some other embodiments, the connection between the first inner conductor 102 and the second inner conductor 12 is not limited to the second magnetic attraction structure. In some other embodiments, the connection structure 13 can also be a second card insertion structure or others.

[0105] In some other embodiments, the connection structure 13 can be a non-independent structural member.
