Compared to a configuration in which an annular electrode connecting member is fitted into the heating element, in the heating assembly and aerosol generator of the present invention, the electrode connecting member is flat and configured to have a first end and a second end in the bending direction. As a result, the electrode connecting member is not annular but flat, and when installed, it can be electrically connected to the electrodes of the heating element by an adhesive method without being fitted into the heating element.

The present invention provides a heating assembly 10 which is specifically used to house an aerosol generating substrate and to heat the aerosol generating substrate when power is applied. The aerosol generating substrate may specifically be a plant leaf substrate or a paste-like substrate. The aerosol generating substrate may be used wrapped in aluminum foil or paper. 【0029】 The heating assembly 10 includes a heating element 11, an electrode 12 (not shown in Figure 1), and an electrode connecting member 13. Specifically, the heating element 11 is used to house an aerosol generating substrate and also contains a heating material. The heating element 11 supports the aerosol generating substrate housed therein and, when energized, generates heat to heat the aerosol generating substrate housed therein, thereby forming an aerosol for use by the user. 【0030】 As shown in Figures 2 and 3, Figure 2 is a schematic diagram of the structure of a heating element 11 and an electrode 12 according to one embodiment of the present application, and Figure 3 is a schematic diagram of the structure of a heating element 11 and an electrode 12 according to another embodiment of the present application. The electrode 12 is provided on the heating element 11 and is electrically connected to the heating element 11. The electrode 12 may be provided on the outer surface of the heating element 11 or on the inner surface of the heating element 11, and in the following embodiment, it is exemplified that the electrode 12 is provided on the outer surface of the heating element 11. 【0031】 There are two electrodes 12, a first electrode 121 and a second electrode 122, which are spaced apart and provided on the heating element 11. The first electrode 121 may be electrically connected to the positive electrode of an external power supply and the second electrode 122 may be electrically connected to the negative electrode of an external power supply, or the first electrode 121 may be connected to the negative electrode of an external power supply and the second electrode 122 may be connected to the positive electrode of an external power supply. In this way, the heating assembly 10 can receive power supplied by an external power supply and energize the heating element 11 to generate heat. 【0032】 The first electrode 121 and the second electrode 122 may be conductive coatings applied to the heating element 11. The conductive coating may be a metal coating, conductive silver paste, conductive tape, or a metal deposited on the surface of the heating element 11, such as a gold film, aluminum film, or copper film. 【0033】 The first electrode 121 and the second electrode 122 each have a connecting portion 123, which is electrically connected to the electrode connecting member 13 and further electrically connected to an external power supply. Here, the connecting portion 123 of the first electrode 121 and the connecting portion 123 of the second electrode 122 may be provided at the same end of the heating element 11 with a gap between them (see Figure 2), or they may be provided at both ends of the heating element 11 (see Figure 3). 【0034】 Specifically, the heating element 11 has opposing first end 111 and second end 112. More specifically, with a plane perpendicular to the axial direction of the heating element 11 and passing through the center point of the heating element 11 as the boundary, the portion of the heating element 11 located on one side of the plane is the first end 111, and the portion of the heating element 11 located on the other side of the plane is the second end 112. 【0035】 In the embodiment shown in Figure 2, the heating element 11 is hollow cylindrical, and the connection portion 123 of the first electrode 121 and the connection portion 123 of the second electrode 122 are spaced apart at the first end 111 of the heating element 11. The first electrode 121 and the second electrode 122 further have a first extension portion 124 connected to their respective connection portions 123, with one end of the first extension portion 124 connected to the connection portion 123 and the other end extending from the connection portion 123 toward the second end 112 of the heating element 11. When current is applied to the first electrode 121 and the second electrode 122, current flows through the heating region between the first extension portion 124 of the first electrode 121 and the first extension portion 124 of the second electrode 122, causing the heating region to heat up and heat the aerosol generating substrate. 【0036】 In the embodiment shown in Figure 3, the first electrode 121 and the second electrode 122 have only a connecting portion 123. The connecting portion 123 of the first electrode 121 is provided at the first end 111 of the heating element 11, and the connecting portion 123 of the second electrode 122 is provided at the second end 112 of the heating element 11. Both the connecting portions 123 of the first electrode 121 and the second electrode 122 are annular. When current is applied to the first electrode 121 and the second electrode 122, current flows in the heating region between the first electrode 121 and the second electrode 122. 【0037】 The heating element 11 may be made of a conductive material as a whole, such as conductive ceramics, or it may include an insulating body 113 and a conductive heating film 114 provided on the surface of the insulating body 113. In this embodiment, the heating element 11 includes a body 113 and a heating film 114. 【0038】 The main body 113 is manufactured from an insulating material, but the main body 113 may be made of a high-temperature resistant insulating material such as quartz glass, ceramics, or mica in order to prevent short circuits between the first electrode 121 and the second electrode 122. The main body 113 has a containment chamber 1131 for containing the aerosol generating substrate. The containment chamber 1131 has an opening at one end, and the aerosol generating substrate can enter and exit the containment chamber 1131 through the opening. The main body 113 may be hollow tubular, and in this embodiment, the main body 113 is a hollow cylindrical body, specifically cylindrical. 【0039】 The heating film 114 generates heat when energized, thereby heating the aerosol generating substrate. The heating film 114 is provided surrounding the outer surface of the main body 113 and may be connected to the first electrode 121 and the second electrode 122, respectively. When energized, current flows through the heating film 114 between the first electrode 121 and the second electrode 122, generating heat. The heating film 114 may be a metal layer, a conductive ceramic layer, or a conductive carbon layer. The shape of the heating film 114 may be a continuous film, a porous mesh, or a strip. 【0040】 As shown in Figure 4, Figure 4 is a schematic diagram of the structure of a heating assembly 10 according to another embodiment of the present application. The heating assembly 10 includes an electrode connecting member 13, which is electrically connected to the electrodes 12 (not shown in Figure 4) of the heating element 11. Specifically, there are two electrode connecting members 13, a first electrode connecting member 131 and a second electrode connecting member 132, which are spaced apart from each other. In this embodiment, the connection portion 123 of the first electrode 121 and the connection portion 123 of the second electrode 122 are both provided at the first end 111 of the heating element 11. The first electrode connecting member 131 is provided at the first end 111 of the heating element 11 and is electrically connected to the connection portion 123 of the first electrode 121, and the second electrode connecting member 132 is provided at the first end 111 of the heating element 11 and is electrically connected to the connection portion 123 of the second electrode 122. 【0041】 In another embodiment, the connection portion 123 of the first electrode 121 and the connection portion 123 of the second electrode 122 are provided at the first end 111 and the second end 112 of the heating element 11, respectively. The first electrode connecting member 131 is provided at the first end 111 of the heating element 11 and is electrically connected to the connection portion 123 of the first electrode 121, and the second electrode connecting member 132 is provided at the second end 112 of the heating element 11 and is electrically connected to the connection portion 123 of the second electrode 122. 【0042】 The electrode connecting member 13 is flat and has a first end and a second end that are spaced apart. Because the first and second ends of the electrode connecting member 13 are spaced apart, the electrode connecting member 13 is flat and not annular, that is, the flat electrode connecting member 13 itself does not form a closed ring. In this embodiment, the heating element 11 is cylindrical, and the electrode connecting member 13 may be arc-shaped, that is, the electrode connecting member 13 is bent, and its bent shape resembles the shape of the heating element 11, so that the arc-shaped electrode connecting member 13 may be attached to the surface of the heating element 11 and come into contact with the electrodes 12 of the heating element 11 for electrical connection. In other embodiments, the heating element 11 may be substantially cylindrical or prismatic, the shape of the electrode connecting member 13 may be similar to the shape of the heating element 11, and the electrode connecting member 13 may be flat and not annular. The material of the electrode connecting member 13 may be a conductive material, such as a metal conductive piece. 【0043】 Compared to the conventional form in which an annular electrode connecting member 13 is fitted into the heating element 11, in the heating assembly 10 and aerosol generator of the present invention, the electrode connecting member 13 is a flat piece and has a first end and a second end spaced apart in the bending direction. That is, because the electrode connecting member 13 is a flat piece rather than an annular piece, when attaching the electrode connecting member 13, it can be electrically connected to the electrodes 12 of the heating element 11 by an adhesive method without being fitted into the heating element 11. This prevents friction between the electrode connecting member 13 and the heating element 11 during assembly and prevents the electrode connecting member from damaging the heating film 114 on the surface of the heating element 11. In this embodiment, the electrode connecting member 13 is an arc-shaped metal piece with a radian of less than 180 degrees. Because the radian is less than 180 degrees, the electrode connecting member 13 is more easily attached to the surface of the cylindrical heating element 11. However, if two electrode connecting members 13 are provided at the same end of the cylindrical heating element 11, the two electrode connecting members 13 may be positioned opposite each other and spaced apart to avoid short circuits. 【0044】 As shown in Figure 5, Figure 5 is a schematic diagram of the disassembled structure of Figure 1. The heating assembly 10 further includes a holder 14, which is provided at the end of the heating element 11 having electrodes 12, and to which an electrode connecting member 13 is fixed. In this embodiment, the first electrode 121 and the second electrode 122 of the heating element 11 are both provided at the first end 111 of the heating element 11, and the holder 14 is also provided at the first end 111 of the heating element 11, and to which the first electrode connecting member 131 and the second electrode connecting member 132 are fixed. Since the electrode connecting member 13 is not annular, it is not possible to fit and fix the electrode connecting member 13 to the heating element 11, and it is necessary to fix the electrode connecting member 13 with the holder 14 to maintain the electrical connection between the first electrode connecting member 131 and the first electrode 121, and between the second electrode connecting member 132 and the second electrode 122. 【0045】 As shown in Figure 5, the holder 14 may be fitted onto the end of the heating element 11 having the electrodes 12. The holder 14 has a base 141 and a cover 142, both of which are fitted onto one end of the heating element 11. In this embodiment, both the base 141 and the cover 142 are fitted onto the first end 111 of the heating element 11, and the electrode connecting member 13 is interposed between the cover 142 and the base 141. When assembling, the base 141 is fitted onto the first end 111 of the heating element 11, then the electrode connecting member 13 is placed on the outer surface of the base 141, and the cover 142 is fitted on the outside of the heating element 11, base 141, and electrode connecting member 13, with the electrode connecting member 13 interposed between the cover 142 and the base 141. Fixing the electrode connecting member 13 by interposing it between the cover 142 and the base 141 provides a simple and stable fixing method. In other embodiments, the holder 14 may fix the electrode connecting member 13 by other means, for example, by engaging with the electrode connecting member 13. 【0046】 In one embodiment, as shown in Figure 6, Figure 6 is a schematic diagram of the structure of a base 141 according to one embodiment of the present invention, the base 141 having a first annular side wall 1411 and a mounting portion 1412, the mounting portion 1412 being provided in the internal space of the first annular side wall 1411 and working in conjunction with the first annular side wall 1411 to form a storage chamber, the first end 111 of the heating element 11 being provided in the storage chamber, the storage chamber may be a storage groove. The mounting portion 1412 has a through hole 1413, the through hole 1413 is in communication with the housing chamber 1131 of the heating element 11, and thereafter, even after the heating element 11 is attached to the base 141, the housing chamber 1131 is in communication with the outside atmosphere and allows airflow to access the aerosol generating substrate in the housing chamber 1131. 【0047】 The cover 142 may be engaged with the base 141. As shown in Figures 6 and 7, Figure 7 is a schematic diagram of the structure of the cover 142 according to one embodiment of the present invention. On the first annular side wall 1411, a flange 1414 is provided on the outer surface away from the second end 112 of the heating element 11 for contact with the bottom surface of the cover 142. The flange 1414 may be an annular protrusion or an arc-shaped flange 1414. In this embodiment, the flange 1414 is two arc-shaped flanges 1414, and a notch 1415 is present on the outer edge of the arc-shaped flange 1414. The cover 142 has a second annular side wall 1421, and an engaging portion 1422 is provided on the second annular side wall 1421. The engaging portion 1422 extends away from the second end 112 of the heating element 11 to the side of the bottom surface of the second annular side wall 1421 away from the second end 112 of the heating element 11, so that when the bottom surface of the base 141 abuts against the flange 1414, the engaging portion 1422 engages with the notch 1415. The method of engagement between the cover 142 and the base 141 is not limited to the engagement structure according to this embodiment. 【0048】 Furthermore, as shown in Figures 6 and 8, Figure 8 is a schematic diagram of the structure of an arc-shaped metal piece according to one embodiment of the present invention. In this embodiment, the electrode connecting member 13 is an arc-shaped metal piece, and the arc-shaped metal piece may be positioned by abutting against the flange 1414 of the first annular side wall 1411. Specifically, the arc-shaped metal piece has a main body portion 133 and a protruding portion 134. The main body portion 133 has a first side 1331 close to the second end 112 of the heating element 11 and a second side 1332 further away from the second end 112 of the heating element 11. The protruding portion 134 is connected to the second side 1332 of the main body portion 133. A gap may exist between two adjacent flanges 1414 of the base 141. During assembly, the second side 1332 of the main body 133 of the arc-shaped metal piece abuts against the flange 1414 of the base 141, and the protruding portion 134 of the arc-shaped metal piece engages with the gap between the two flanges 1414. 【0049】 As shown in Figure 5, the first portion 135 of the electrode connecting member 13 is exposed to the base 141 and contacts the electrode 12 of the heating element 11. Specifically, the first annular side wall 1411 does not completely cover the electrode 12 at the first end 111 of the heating element 11, the electrode connecting member 13 is provided on the outer surface of the first annular side wall 1411, and the electrode connecting member 13 is partially extended from the first annular side wall 1411 and exposed, the portion of the electrode connecting member 13 extending from the first annular side wall 1411 becomes the first portion 135 of the electrode connecting member 13, and the first portion 135 of the electrode connecting member 13 may be connected in contact with the electrode 12 at the first end 111 of the heating element 11. Alternatively, as shown in Figure 5, the first annular side wall 1411 may have a first opening 1411a, the first opening 1411a exposing the electrode 12 at the first end 111 of the heating element 11, a part of the electrode connecting member 13 being exposed through the first opening 1411a, the portion of the electrode connecting member 13 exposed through the first opening 1411a becoming the first part 135 of the electrode connecting member 13, and the first part 135 of the electrode connecting member 13 being in contact with and connected to the electrode 12 at the first end 111 of the heating element 11 through the first opening 1411a. According to the above embodiment, the electrode connecting member 13 can be fixed to the base 141, and an electrical connection between the electrode connecting member 13 and the electrode 12 can be achieved. 【0050】 In this embodiment, as shown in Figure 8, the arc-shaped metal piece further includes a first contact portion 137, which is connected to the first side edge 1331 of the main body portion 133. In the first contact portion 137, the end away from the main body portion 133 is bent toward the heating element 11 to form an elastic contact, and the first portion 135 of the electrode connecting member 13 is the bent portion of the first contact portion 137, and the elastic contact is exposed through the first opening 1411a and contacts the electrode 12. When the first contact portion 137 contacts the electrode 12, it generates an elastic force, thereby ensuring good contact between the first contact portion 137 and the electrode 12. There may be multiple first contact portions 137; for example, in this embodiment, there are two first contact portions 137. The more first contact portions 137 there are, the more stable the electrical connection between the first contact portions 137 and the electrode 12 becomes. 【0051】 Furthermore, the arc-shaped metal piece further includes a plurality of second extensions 138 connected to the first side 1331 of the main body 133, all of which are provided on the first annular side wall 1411, and the plurality of second extensions 138 and the plurality of first contacts 137 are alternately provided on the first side 1331. In this embodiment, the number of plurality of second extensions 138 is two, and the two second extensions 138 and the two first contacts 137 are alternately provided. By providing the second extensions 138, The structure of the arc-shaped metal piece becomes more stable. 【0052】 As shown in Figure 9, Figure 9 is a schematic diagram of the structure when the electrode connecting member 13 of Figure 5 is attached to the base 141. The second portion 136 of the electrode connecting member 13 is exposed on the top base and connected to an external power supply. As shown in Figure 9, the cover 142 may have a second opening 1421a in its second annular side wall 1421, which exposes a portion of the electrode connecting member 13. The exposed portion becomes the second portion 136 of the electrode connecting member 13. Specifically, as shown in Figures 8 and 9, the protrusion 134 and a portion of the main body 133 are the second portion 136 of the electrode connecting member 13 and are exposed through the second opening 1421a. This allows the external power supply to be electrically connected to the electrodes 12 of the heating element 11 by being electrically connected to the protrusion 134 and a portion of the main body 133 through the second opening 1421a. In other embodiments, a portion of the electrode connecting member 13 may extend from the second annular side wall 1421, and the extended portion becomes the second portion 136 of the electrode connecting member 13. 【0053】 As shown in Figures 9 and 10, Figure 10 is a schematic structural diagram of the heating assembly 10 of Figure 1 from a different viewing angle. In one embodiment, the ends of the base 141 and cover 142 closer to the second end 112 of the heating element 11 are fitted onto the first end 111 of the heating element 11, while the ends of the base 141 and cover 142 further away from the second end 112 of the heating element 11 are suspended. The second portion 136 of the electrode connecting member 13 is provided on the suspended first annular side wall 1411 and is exposed through the second opening 1421a. By providing the second portion 136 of the electrode connecting member 13 on the first annular side wall 1411, when the external leads or external dome are electrically connected to the second portion 136 of the electrode connecting member 13, the heating element 11 does not receive direct force, but mainly receives force through the first annular side wall 1411 of the base 141, thereby preventing damage to the heating film 114 of the heating element 11 from being directly subjected to force. Furthermore, by providing the second portion 136 of the electrode connecting member 13 on the first annular side wall 1411 which is suspended, the force received by the heating element 11 can be further reduced, preventing damage to the heating element 11. 【0054】 As shown in Figure 11, Figure 11 is a schematic diagram of the structure of an aerosol generator and an aerosol generating substrate according to one embodiment of the present invention. The present invention provides an aerosol generator comprising a housing 20, a heating assembly 10 (not shown), and a power supply assembly 30 (not shown). Both the heating assembly 10 and the power supply assembly 30 are provided within the housing 20, and mounting holes 21 are provided in the top wall of the housing 20. The mounting holes 21 correspond to the housing chamber 1131 within the heating element 11 of the heating assembly 10, thereby allowing the aerosol generating substrate to be inserted into and removed from the heating element 11 through the mounting holes 21. 【0055】 The heating assembly 10 may specifically be the heating assembly 10 according to any of the embodiments, and its specific structure and function can be described by referring to the description related to the heating assembly 10 of the embodiments above, and the same or similar technical effects can be achieved, specifically refer to the following. 【0056】 In the aerosol generator according to this embodiment, a heating assembly 10 is provided, and in the heating assembly 10, the electrode connecting member 13 is configured as a non-annular, flat shape. When attaching the electrode connecting member 13, instead of fitting it onto the heating element 11, the electrode connecting member 13 can be electrically connected to the electrode 12 of the heating element 11 by an adhesive method. This prevents friction between the electrode connecting member 13 and the heating element 11 during assembly and prevents the electrode connecting member 13 from damaging the heating film 114 or heating coating on the surface of the heating element 11. 【0057】 As shown in Figure 12, Figure 12 is a schematic diagram of the structure of the central part of the assembly of an aerosol generator according to one embodiment of the present invention. The power supply assembly 30 includes a bracket 31, a control circuit board (not shown), a battery 32, and an intake pipe 33. The heating assembly 10, the control circuit board, and the battery 32 are all fixed within the bracket 31. 【0058】 The control circuit board is electrically connected to both the heating assembly 10 and the battery 32, receives a start signal, controls the battery 32 to supply power to the heating assembly 10, controls the heating assembly 10 to operate, and may also control the heating power and heating time of the heating assembly 10. 【0059】 The intake pipe 33 has one end connected to the first end 111 of the heating element 11 and communicates with the containment chamber 1131 of the heating element 11, and the other end communicates with the outside atmosphere. As a result, when a user inhales from the second end 112 side of the heating element 11, the outside atmosphere enters the aerosol generating substrate inside the containment chamber 1131 of the heating element 11, and the atomized aerosol is carried out of the aerosol generating device for use by the user. 【0060】 As shown in Figures 12 to 14, Figure 13 is a schematic diagram of the structure of a conductive member 34 according to one embodiment of the present invention, and Figure 14 is a schematic diagram of the structure of a conductive member 34 and a heating assembly 10 according to one embodiment of the present invention. In one embodiment, the power supply assembly 30 further includes a conductive member 34 fixed to a bracket 31. The conductive member 34 is electrically connected to a control circuit board, and the conductive member 34 is in contact with an electrode connecting member 13, thereby enabling the control circuit board to be electrically connected to the electrode connecting member 13 via the conductive member 34. 【0061】 The conductive member 34 includes a main body 341, a second contact portion 342, and a fixing portion 343. The main body 341 is fixedly connected to the bracket 31, and the fixing method may be by screw fixing as in this embodiment, or by adhesive or engagement methods. In one embodiment, the conductive member 34 is a metal piece, and the main body 341, the second contact portion 342, and the fixing portion 343 are integrally molded. 【0062】 The second contact portion 342 and the fixing portion 343 are each connected to the main body portion 341. The fixing portion 343 has an external lead welded to it, which is electrically connected to the control circuit board. The lead wire and the second contact portion 342 contact the exposed second portion 136 of the electrode connecting member 13 of the heating assembly 10, thereby achieving an electrical connection between the conductive member 34 and the electrode connecting member 13. There are two conductive members 34; one of the two conductive members 34 contacts the first electrode connecting member 131 and is connected to the positive electrode lead wire, and the other contacts the second electrode connecting member 132 and is connected to the negative electrode lead wire. 【0063】 In one embodiment, the second contact portion 342 is bent towards the electrode connecting member 13, with its convex surface facing the electrode connecting member 13, thereby imparting elasticity to the second contact portion 342. The convex surface of the second contact portion 342 abuts against the second portion 136 of the electrode connecting member 13. The bending of the second contact portion 342 generates an elastic force when the second contact portion 342 and the electrode 12 come into contact, ensuring good contact between the second contact portion 342 and the electrode 12. 【0064】 By providing a conductive member 34 in the aerosol generator, when assembling, the external leads can be welded to the conductive member 34 instead of directly welding them to the electrode connection member 13. This significantly reduces the force the heating element 11 experiences during assembly and avoids damage to the heating film 114 of the heating element 11. 【0065】 The above describes only embodiments of the present application and does not limit the scope of the patent. Any transformation of equivalent structures or equivalent flows using the contents of the specification and drawings of the present application, or any use in other related technical fields, directly or indirectly, shall all similarly fall within the scope of the patent protection of the present application.
