[0031] The one or more electrodes 12 include two electrodes, and the two electrodes include a first electrode 121 and a second electrode 122. The first electrode 121 and the second electrode 122 are spaced apart from each other on the heating element 11. The first electrode 121 may be configured to be electrically connected to a positive pole of an external power supply, and the second electrode 122 may be configured to be electrically connected to a negative pole of the external power supply.

[0032] Each of the first electrode 121 and the second electrode 122 may be a conductive coating coated on the heating element 11. The conductive coating may be a metal coating, a conductive silver paste, a conductive tape, and so on, or may be metals deposited on the surface of the heating element 11, such as gold film, aluminum film, or copper film.

[0033] Each of the first electrode 121 and the second electrode 122 has a connecting portion 123. Each connecting portion 123 is configured to be electrically connected to a corresponding electrode connecting element 13 of the one or more electrode connecting elements 13, thereby being electrically connected to the external power supply. The connecting portion 123 of the first electrode 121 and the connecting portion 123 of the second electrode 122 may be spaced apart from each other on the same end of the heating element 11 (as shown in FIG. 2), or may be respectively arranged on two ends of the heating element 11 (as shown in FIG. 3).

[0034] In some embodiments, the heating element 11 has a first end 111 and a second end 112 opposite to each other. A plane perpendicular to the axial direction of the heating element 11 and passing through the center point of the heating element 11 is taken as a boundary, a portion of the heating element 11 located on one side of the plane is the first end 111 of the heating element 11, and the other portion of the heating element 11 located on the other side of the plane is the second end 112 of the heating element 11.

[0035] In the embodiments shown in FIG. 2, the heating element 11 is a hollow column. The connecting portion 123 of the first electrode 121 and the connecting portion 123 of the second electrode 122 are spaced apart from each other on the first end 111 of the heating element 11. Each of the first electrode 121 and the second electrode 122 also has a first extending portion 124 connected to the connecting portion 123 thereof. One end of the first extending portion 124 is connected to the connecting portion 123, and the other end of the first extending portion 124 is extended from the connecting portion 123 towards the second end 112 of the heating element 11. After the first electrode 121 and the second electrode 122 are powered on, there is a current flowing through a heating zone between the first extending portion 124 of the first electrode 121 and the first extending portion 124 of the second electrode 122, and the heating zone heats the aerosol generation substrate.

[0036] In the embodiments shown in FIG. 3, each of the first electrode 121 and the second electrode 122 only has the connecting portion 123, the connecting portion 123 of the first electrode 121 is arranged on the first end 111 of the heating element 11, and the connecting portion 123 of the second electrode 122 is arranged on the second end 112 of the heating element 11. The connecting portion 123 of the first electrode 121 and the connecting portion 123 of the second electrode 122 are both annular-shaped. After the first electrode 121 and the second electrode 122 are powered on, there is a current flowing through a heating zone between the first electrode 121 and the second electrode 122.

In some embodiments, the heating element 11 includes a base body 113 and a heating film 114.

[0038] The base body 113 may be made of insulating materials. The base body 113 may be insulating materials with high thermostability, such as quartz glass, ceramic, mica, and so on, so to prevent short circuit between the first electrode 121 and the second electrode 122. The base body 113 has a receiving chamber 1131. The receiving chamber 1131 is configured to receive the aerosol generation substrate. One end of the receiving chamber 1131 has an opening, in this way, the aerosol generation substrate may be inserted into or retreated from the receiving chamber 1131 through the opening. The base body 113 may be a hollow tube. In some embodiments, the base body 113 is a hollow column, and is cylinder-shaped.

[0039] The heating film 114 may generate heat when being powered on, so as to heat the aerosol generation substrate. The heating film 114 may be arranged around the outer surface of the base body 113 and connected to each of the first electrode 121 and the second electrode 122. After the first electrode 121 and the second electrode 122 are powered on, there is a current flowing through the heating film 114 between the first electrode 121 and the second electrode 122, and heat is generated. The heating film 114 may be a metal layer, a conductive ceramic layer, or a conductive carbon layer. The heating film 114 may be a continuous film, may be porous mesh-shaped, or may be strip-shaped.

[0040] As shown in FIG. 4, FIG. 4 is a schematic structural view of a heating assembly 10 according to some embodiments of the present disclosure. The heating assembly 10 includes one or more electrode connecting elements 13. The one or more electrode connecting elements 13 are electrically connected to the one or more electrodes 12 (which are not shown in FIG. 4) on the heating element 11. In some embodiments, the one or more electrode connecting elements 13 include two electrode connecting elements 13, and the two electrode connecting elements 13 include a first electrode connecting element 131 and a second connecting element 132 spaced apart from each other. In some embodiments, the connecting portion 123 of the first electrode 121 and the connecting portion 123 of the second electrode 122 are both arranged on the first end 111 of the heating element 11. The first electrode connecting element 131 is arranged on the first end 111 of the heating element 11, and is electrically connected to the connecting portion 123 of the first electrode 121. The second electrode connecting element 132 is arranged on the first end 111 of the heating element 11, and is electrically connected to the connecting portion 123 of the second electrode 122.

[0041] In some embodiments, the connecting portion 123 of the first electrode 121 is arranged on the first end 111 of the heating element 11, and the connecting portion 123 of the second electrode 122 is arranged on the second end 112 of the heating element 11. The first electrode connecting element 131 is arranged on the first end 111 of the heating element 11, and is electrically connected to the connecting portion 123 of the first electrode 121. The second electrode connecting element 132 is arranged on the second end 112 of the heating element 11, and is electrically connected to the connecting portion 123 of the second electrode 122.

[0042] Each electrode connecting element 13 is sheet-shaped. Each electrode connecting element 13 has a first end portion and a second end portion spaced apart from each other. The first end portion and the second end portion of each electrode connecting element 13 are spaced apart from each other, and each electrode connecting element 13 is in the shape of a non-annular sheet. That is, each electrode connecting element 13 is not enclosed to form a ring. In some embodiments, the heating element 11 is cylinder-shaped, and each electrode connecting element 13 may be curved. That is, each electrode connecting element 13 is bent, and the bent shape of each electrode connecting element 13 is similar to the shape of the heating element 11. In this way, each curved electrode connecting element 13 may be attached to the surface of the heating element 11 and electrically connected to a corresponding electrode 12 of the electrodes 12 on the heating element 11. In some embodiments, the shape of the heating element 11 may be similar to a cylinder, or the heating element 11 may be prism-shaped, and so on. The shape of each electrode connecting element 13 may also be similar to the shape of the heating element 11, as long as each electrode connecting element 13 is in the shape of a non-annular sheet. Each electrode connecting element 13 may be made of conductive materials, for example, each electrode connecting element 13 may be a metal conductive sheet.

[0043] Compared with the mode in the related art in which an annular electrode connecting element is sleeved on the heating element 11, in the heating assembly 10 and the aerosol generation apparatus provided by some embodiments of present disclosure, each electrode connecting element 13 is sheet-shaped, and has a first end portion and a second end portion spaced apart from each other along the bending direction of each electrode connecting element 13. That is, each electrode connecting element 13 is in the shape of a non-annular sheet. When being assembled, each electrode connecting element 13 may be electrically connected to the corresponding electrode 12 on the heating element 11 by the way of attaching to the heating element 11, instead of being sleeved on the heating element 11, in this way, the friction between each electrode connecting element 13 and the heating element 11 may be avoided during assembly, thereby avoiding the heating film 114 on the surface of the heating element 11 from being scratched. In some embodiments, each electrode connecting element 13 is a curved metal sheet, and the radian of the curved metal sheet is less than 180 degrees. On one hand, the radian is less than 180 degrees, it is easy for each electrode connecting element 13 to be attached to the surface of the cylindrical heating element 11. On the other hand, when the two electrode connecting elements 13 are arranged on the same end of the cylindrical heating element 11, the two electrode connecting elements 13 may be arranged opposite to each other and spaced apart from each other, in this way, short circuit may be avoided.

[0044] As shown in FIG. 5, FIG. 5 is a schematic exploded structural view of FIG. 1. The heating assembly 10 also includes a fixing base 14. The fixing base 14 is arranged on the end of the heating element 11 which is provided with the electrodes 12 and is configured to fix the electrode connecting elements 13. In some embodiments, the first electrode 121 and the second electrode 122 on the heating element 11 are both arranged on the first end 111 of the heating element 11. The fixing base 14 is also arranged on the first end 111 of the heating element 11 and configured to fix the first electrode connecting element 131 and the second electrode connecting element 132. Each electrode connecting element 13 is non-annular, and therefore cannot be fixed by being sleeved on the heating element 11. Each electrode connecting element 13 is needed to be fixed through the fixing base 14, in this way, the first electrode connecting element 131 may be electrically connected to the first electrode 121, and the second electrode connecting element 132 may be electrically connected to the second electrode 122.

[0045] As shown in FIG. 5, the fixing base 14 may be sleeved on the end of the heating element 11 which is provided with the electrodes 12. The fixing base 14 includes a base 141 and an upper cover 142. The base 141 and the upper cover 142 are both sleeved on the end of the heating element 11. In some embodiments, the base 141 and the upper cover 142 are both sleeved on the first end 111 of the heating element 11, and each electrode connecting element 13 is sandwiched between the upper cover 142 and the base 141. During assembly, after the base 141 is sleeved on the first end 111 of the heating element 11, each electrode connecting element 13 is arranged on the outer side surface of the base 141, then the upper cover 142 is sleeved on the outer side of the heating element 11, the base 141, and each electrode connecting element 13. Each electrode connecting element 13 is sandwiched between the upper cover 142 and the base 141. Each electrode connecting element 13 is fixed by being sandwiched between the upper cover 142 and the base 141, the fixing mode is simple and stable. In some embodiments, the fixing base 14 may also fix each electrode connecting element 13 by other modes. For example, the fixing base 14 may be clamped or engaged with each electrode connecting element 13 to fix each electrode connecting element 13.

[0046] In some embodiments, as shown in FIG. 6, FIG. 6 is a schematic structural view of a base 141 according to some embodiments of the present disclosure. The base 141 includes a first annular sidewall 1411 and a mounting portion 1412. The mounting portion 1412 is arranged in the internal space of the first annular sidewall 1411 and forms an accommodating chamber in cooperation with the first annular sidewall 1411. The first end 111 of the heating element 11 is arranged in the accommodating chamber. The accommodating chamber may be an accommodating groove. The mounting portion 1412 defines a through hole 1413. The through hole 1413 is in communication with the receiving chamber 1131 of the heating element 11. In this way, after the heating element 11 is assembled with the base 141, the receiving chamber 1131 may also be in communication with the external air, and an air flow may enter the aerosol generation substrate in the receiving chamber 1131.

Another part of each electrode connecting element 13 is exposed through a corresponding second opening 1421a of the one or more second openings 1421a. The exposed another part is the second portion 136 of each electrode connecting element 13. In some embodiments, as shown in FIGS. 8 and 9, the protruding portion 134 and a part of the body portion 133 are the second portion 136 of each electrode connecting element 13 and are exposed through the corresponding second opening 1421a. In this way, the external power supply may be electrically connected to the protruding portion 134 and the part of the body portion 133 through the corresponding second opening 1421a, and thereby being electrically connected to the corresponding electrode 12 on the heating element 11. In some embodiments, a part of each electrode connecting element 13 may be extended out of the second annular sidewall 1421, and the part of each electrode connecting element 13 extended out of the second annular sidewall 1421 is the second portion 136 of each electrode connecting element 13.

[0053] As shown in FIGS. 9 and 10, FIG. 10 is another schematic structural view of the heating assembly 10 shown in FIG. 1 viewed from another angle. In some embodiments, one end of the base 141 close to the second end 112 of the heating element 11 and one end of the upper cover 142 close to the second end 112 of the heating element 11 are sleeved on the first end 111 of the heating element 11, and the other end of the base 141 away from the second end 112 of the heating element 11 and the other end of the upper cover 142 away from the second end 112 of the heating element 11 are suspended. The second portion 136 of each electrode connecting element 13 is arranged on the suspended portion of the first annular sidewall 1411 and is exposed through the corresponding second opening 1421a. By arranging the second portion 136 of each electrode connecting element 13 on the first annular sidewall 1411, when an external leading wire or an external elastic sheet is electrically connected to the second portion 136 of each electrode connecting element 13, force is not directly acted on the heating element 11 and is mainly acted on the first annular sidewall 1411 of the base 141. In this way, it may be avoided that force is directly acted on the heating element 11. When the force is directly acted on the heating element 11, the heating film 114 of the heating element 11 may be damaged. In some embodiments, the second portion 136 of each electrode connecting element 13 is arranged on the suspended portion of the first annular sidewall 1411, in this way, the force act on the heating element 11 may be further reduced, so as to avoid the heating element 11 from being damaged.

The control circuit board is configured to control the battery 32 to power the heating assembly 10 and control the operation of the heating assembly 10 after receiving an enable signal. The control circuit board may also be configured to control the heating power, heating duration, and so on, of the heating assembly 10.

[0059] One end of the air intake pipe 33 is connected to the first end 111 of the heating element 11 and is in communication with the receiving chamber 1131 of the heating element 11. The other end of the air intake pipe 33 is in communication with external air. In this way, when the user inhales from the second end 112 of the heating element 11, the external air may enter the aerosol generation substrate in the receiving chamber 1131 of the heating element 11 and carry the atomized aerosols to flow out of the aerosol generation apparatus for the user.

[0060] As shown in FIGS. 12 to 14, FIG. 13 is a schematic structural view of a conductive element according to some embodiments of the present disclosure, and FIG. 14 is a schematic structural view of a conductive element 34 and a heating assembly 10 according to some embodiments of the present disclosure. In some embodiments, the power supply assembly 30 may also include one or more conductive elements 34. Each of the one or more conductive elements 34 is fixed on the bracket 31. Each of the one or more conductive elements 34 is electrically connected to the control circuit board, and abuts against a corresponding electrode connecting element 13 of the one or more electrode connecting elements 13, in this way, the control circuit board may be electrically connected to the one or more electrode connecting elements 13 through the one or more conductive elements 34.

[0061] Each of the one or more conductive elements 34 includes a main portion 341, a second abutting portion 342, and a fixing portion 343. The main portion 341 is fixed on the bracket 31. In some embodiments, the main portion 341 may be fixed on the bracket 31 through a screw. In some embodiments, the main portion 341 may be fixed on the bracket 31 by the mode of adhering, engaging, and so on. In some embodiments, each conductive element 34 is a metal sheet, and the main portion 341, the second abutting portion 342, and the fixing portion 343 are integrally formed.

[0062] The second abutting portion 342 and the fixing portion 343 are connected to the main portion 341 respectively. The fixing portion 343 may be configured to be welded with an external leading wire, and is electrically connected to the control circuit board through the external leading wire. The second abutting portion 342 abuts against the exposed second portion 136 of the corresponding electrode connecting element 13 of the heating assembly 10, so as to realize electric connection between each conductive element 34 and the corresponding electrode connecting element 13. The one or more conductive elements 34 include two conductive elements 34. One of the two conductive elements 34 abuts against the first electrode connecting element 131 and is connected to a positive leading wire, and the other of the two conductive elements 34 abuts against the second electrode connecting element 132 and is connected to a negative leading wire.

[0063] In some embodiments, the second abutting portion 342 is bent to the corresponding electrode connecting element 13, the convex face of the second abutting portion 342 faces the corresponding electrode connecting element 13, and the second abutting portion 342 is elastic. The convex surface of the second abutting portion 342 abuts against the second portion 136 of the corresponding electrode connecting element 13. By bending the second abutting portion 342, an elastic force may be generated when the second abutting portion 342 abuts against the corresponding electrode 12, in this way, the second abutting portion 342 may be well contacted with the corresponding electrode 12.

[0064] By arranging the one or more conductive elements 34 in the aerosol generation apparatus, the external leading wire may be welded to the one or more conductive elements 34 during assembly instead of being directly welded to the one or more electrode connecting elements 13, in this way, the force act on the heating element 11 may be further reduced during assembly, thereby preventing the heating film 114 on the heating element 11 from being damaged.
