Description

Technical Field

[0001] This application relates to the field of aerosol generation device technology, specifically to a heating component and an aerosol generation device. Background Technology

[0002] Currently, heated non-combustible aerosol generators typically use a heating element to heat an aerosol generating rod placed inside a heating chamber, causing the internal atomizing matrix to atomize and generate aerosols. However, some heat loss is inevitable during heating, affecting heating efficiency and increasing energy consumption. Therefore, reducing heat loss from the heating element has become a key issue affecting aerosol generators. Existing products often employ insulation structures to reduce heat loss, such as adding a vacuum insulation tube around the periphery of the heating chamber. While this enhances insulation to some extent, the vacuum insulation tube and the heating element are independent, making it difficult to combine heat conduction and insulation. This increases the complexity of the overall structure, hinders cost control, and limits the heating coverage to the circumferential side, resulting in limited heating effectiveness.

[0041] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0042] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0043] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0044] An aerosol generator is a special atomizing product containing an atomizing matrix. When in use, it is inserted into a matching heated non-combustible aerosol generator. The heating device heats the aerosol generator, causing the atomizing matrix inside the aerosol generator to atomize and generate an aerosol. As the user draws the aerosol generator, the aerosol moves with the airflow to the suction end.

[0045] The heating component and aerosol generating device provided in this application change the existing structural form of separate heat-conducting and heat-insulating structures. By setting a vacuum insulation cavity between the first and second cup walls of the heating cup, the second cup wall is located inside the first cup wall and is a heat-conducting structure. A heating element is set in the heating cavity corresponding to the inner bottom wall of the second cup wall. When the aerosol generating rod is inserted into the heating cavity, the heat generated by the heating element can be conducted to the inner wall through the inner bottom wall of the second cup wall to heat the aerosol generating rod in the circumferential direction, and can also radiate heat directly to the aerosol generating rod in the first direction through the heating element, forming dual heating. Moreover, the vacuum insulation cavity can simultaneously provide heat insulation in the circumference and bottom of the aerosol generating rod, so that heating and heat insulation functions are integrated into the heating cup.

[0046] The following describes some embodiments of the heating components and aerosol generating apparatus provided in this application with reference to the accompanying drawings.

[0047] The first aspect of this application provides a heating assembly 100, such as... Figure 1 , Figure 2 As shown, the heating assembly 100 includes a heating cup 1 and a heating element 2. The heating cup 1 has a heating cavity 123, and one end of the heating cavity 123 in a first direction has an insertion port 14 for aerosol to pass through and be inserted into the heating cavity 123. The heating cup 1 has a first cup wall 11 and a second cup wall 12, the second cup wall 12 being located inside the first cup wall 11. The first cup wall 11 and the second cup wall 12 are interconnected and form a vacuum insulation cavity 13 between the first cup wall 11 and the second cup wall 12. The second cup wall 12 is a heat-conducting structure, and the second cup wall 12 includes an inner side wall 121 and an inner bottom wall 122 that are interconnected. The inner side wall 121 and the inner bottom wall 122 form the heating cavity 123, and the inner bottom wall 122 is disposed opposite to the insertion port 14 in the first direction. A heating element 2 is provided at one end of the heating chamber 123 facing the inner bottom wall 122, and in a first direction, the heating element 2 covers at least part of the inner bottom wall 122. When the aerosol generating rod 600 is inserted into the heating chamber 123, the heating element 2 is opposite to the end face of the aerosol generating rod 600 in the first direction. The heating element 2 can generate heat when energized. At this time, the heating element 2 can directly radiate heat to the end face of the aerosol generating rod 600, and can also conduct heat to the inner side wall 121 through the inner bottom wall 122 of the second cup wall 12, thereby heating the circumference of the aerosol generating rod 600 through the inner side wall 121, forming dual heating. During the heating process, the vacuum insulation chamber 13 of the heating cup 1 can simultaneously provide insulation in the circumference and bottom of the aerosol generating rod 600, so that heating and insulation functions are integrated into the heating cup 1.

[0048] It is understandable that in existing vacuum insulation chamber aerosol generating devices, the heat conduction structure and the heat insulation structure are separated. For example, an independent heating tube is set inside the vacuum insulation tube. Although this can enhance the heat insulation effect to a certain extent, this structural form increases the complexity of the overall structure. Moreover, the heating method is singular, and the heating range is limited to the circumference of the aerosol generating rod. The heating condition of the aerosol generating rod near the center is poor, which affects the overall heating effect.

[0049] In this embodiment, the heating component 100 improves and optimizes its structure by setting a vacuum insulation cavity 13 between the first cup wall 11 and the second cup wall 12 of the heating cup 1, thus combining the heating cavity 123 and the vacuum insulation cavity 13. This eliminates the need for additional insulation structures, simplifies the overall structure, and increases the heating coverage area. In use, the heating element 2 can transfer heat to the aerosol generating rod circumferentially through the inner wall of the heating cavity 123, and can also radiate heat directly to the aerosol generating rod in the first direction, effectively enhancing the heating atomization effect.

[0050] It should be noted that in practical applications, the shape and size of the heating chamber 123 are adapted to the shape and size of the aerosol generating rod 600 to ensure that the aerosol generating rod 600 can be inserted into the heating chamber 123 for normal heating. Specifically, when the aerosol generating rod 600 is inserted into the heating chamber 123, an appropriate gap is maintained between the second cup wall 12 of the heating cup 1 and the aerosol generating rod 600 to allow airflow. This allows external air to pass through the gap and flow to the insertion end of the aerosol generating rod 600. When the user performs a suction action, the airflow can be drawn into the aerosol generating rod 600 under negative pressure and mix with the generated aerosol to form an aerosol mixture.

[0051] Furthermore, in practical applications, the vacuum insulation cavity 13 can be specifically configured as follows: Figure 1 and Figure 2 The state shown is that the vacuum insulation cavity 13 includes the portion located on the outer periphery of the heating cavity 123 and the portion on the outer side of the inner bottom wall 122. Of course, the vacuum insulation cavity 13 can also be configured to include only the portion on the outer periphery of the heating cavity 123, while the portion on the outer side of the inner bottom wall 122 is set as a solid structure. The specific configuration can be determined according to the actual usage requirements.

[0052] In further embodiments of this application, such as Figures 1 to 3As shown, in the first direction, the heating chamber 123 includes a first heating section 1231 and a second heating section 1232 connected in sequence. The first heating section 1231 is located inside the heating chamber 123 near the insertion port 14, and the second heating section 1232 is located inside the heating chamber 123 near the inner bottom wall 122. The ends of the first heating section 1231 and the second heating section 1232 facing the insertion port 14 are connected. The heating element 2 is disposed inside the second heating section 1232. A support member 124 is provided between the second heating section 1232 and the first heating section 1231. When the aerosol generating rod 600 is inserted into the heating chamber 123, the support member 124 abuts against the insertion end of the aerosol generating rod 600 to provide support for the aerosol generating rod 600, so that the aerosol generating rod 600 is kept inside the first heating section 1231, preventing the aerosol generating rod 600 from directly contacting the heating element 2. This can prevent the aerosol generating rod 600 from being over-baked and producing a burnt taste that affects the smoking experience.

[0053] Furthermore, in a specific implementation, such as Figure 2 In the example, in the first direction, one side of the heating element 2 abuts against the inner bottom wall 122 of the second cup wall 12, so as to improve the heat transfer efficiency to the inner bottom wall 122 when the heating element 2 is heating, which is beneficial to enhance the heating effect of the second cup wall 12 on the aerosol generating rod 600; the other side of the heating element 2 abuts against the support member 124, so that the support member 124 and the inner bottom wall 122 form a clamp on both sides of the heating element 2, so as to keep the heating element 2 fixed, enhance the assembly stability of the heating element 2, and prevent the heating element 2 from shaking and affecting the heating effect. In the first direction, there is a preset distance 'a' between the heating element 2 and the first heating section 1231, so that when the aerosol generating rod 600 is inserted into the first heating section 1231, sufficient space can be reserved between the heating element 2 and the suction end of the aerosol generating rod 600 for airflow to pass through, and at the same time, it can further prevent the suction end of the aerosol generating rod 600 from being too close to the heating element 2, which would cause overheating.

[0054] In further embodiments of this application, such as Figure 4 , Figure 5 As shown, the heating element 2 includes a main heating element 21 and a heat insulation element 22. The main heating element 21 and the heat insulation element 22 are stacked in a first direction, and the heat insulation element 22 is located on any side surface of the main heating element 21 in the first direction, for example... Figure 4 In the example shown, the heat insulation element 22 is located on the surface of the main heating element 21 facing the inner bottom wall 122, or as... Figure 5 In the example, the heat insulation element 22 is located on the surface of the main heating element 21 facing the insertion port 14. The thermal conductivity of the heat insulation element 22 is less than that of air, which is used to reduce the amount of heat transferred by the main heating element 21 on the side facing the heat insulation element 22, so as to reduce the heat transfer ratio between the two heat transfer modes of the heating element 2.

[0055] For example, when it is necessary to reduce the heat transfer from the heating element 2 to the second cup wall 12 of the heating cup 1, a heat insulation element 22 can be provided on the surface of the main heating element 21 facing the inner bottom wall 122 of the second cup wall 12, such as... Figure 4 In the example, when the main heating element 21 is heating, the heat transfer from the main heating element 21 to the inner bottom wall 122 is reduced, thereby reducing the amount of heat transferred to the aerosol generating rod 600 through the second cup wall 12. This can be achieved by correspondingly increasing the proportion of radiant heat directly radiated to the aerosol generating rod 600 by the main heating element 21. When it is necessary to reduce the radiant heat directly radiated to the aerosol generating rod 600 by the heating element 2, a heat insulation element 22 can be provided on the surface of the main heating element 21 facing the insertion port 14, such as... Figure 5 In the example above, when the main heating element 21 is heating, reducing the direct radiant heat from the main heating element 21 to the aerosol generating rod 600 can correspondingly increase the proportion of heat transferred from the main heating element 21 to the aerosol generating rod 600 through the second cup wall 12. When the heating assembly 100 is applied in an aerosol generating device, the above settings allow for targeted adjustment of the ratio between the direct radiant heat from the heating element 2 to the aerosol generating rod 600 and the heat conducted through the second cup wall 12, based on the different heating requirements of different types of aerosol generating rods 600. This ensures that the overall heating of the aerosol generating rod 600 matches its type, thereby improving heating and atomization efficiency, accelerating aerosol generation, reducing user waiting time, and also improving heat utilization efficiency and reducing energy waste.

[0056] In practical applications, the thermal insulation component 22 can be an insulating sheet, specifically made of glass sheets or glass cloth (e.g., quartz glass sheets, high borosilicate glass sheets, high aluminosilicate glass), or ceramic sheets, ceramic cloth, or ceramic felt (e.g., zirconia, alumina, mullite, cordierite, andalusite, basalt, zirconia-reinforced zirconia ZTA, kaolin ceramics), or vacuum panels (e.g., VIP panels) or aerogel, etc.; moreover, the thermal insulation component 22 can be set with an appropriate size according to the required heat transfer ratio.

[0057] In further embodiments of this application, such as Figure 6 and Figure 7 As shown, the heating element 2 includes a main heating element 21 and a heat-conducting element 23. The main heating element 21 and the heat-conducting element 23 are stacked in a first direction, and the heat-conducting element 23 is located on any side surface of the main heating element 21 in the first direction, for example... Figure 6 In the example shown, the heat-conducting element 23 is located on the surface of the main heating element 21 facing the inner bottom wall 122, or as... Figure 7In the example, the heat-conducting element 23 is located on the surface of the main heating element 21 facing the insertion port 14. The thermal conductivity of the heat-conducting element 23 is greater than that of air, used to increase the amount of heat transferred from the main heating element 21 to the side facing the heat-conducting element 23, thus increasing the heat transfer ratio between the two heat transfer methods of the heating element 2.

[0058] For example, when it is necessary to increase the heat transfer from the heating element 2 to the second cup wall 12 of the heating cup 1, a heat-conducting element 23 can be provided on the surface of the main heating element 21 facing the inner bottom wall 122 of the second cup wall 12, such as... Figure 6 In the example, when the main heating element 21 is heating, the heat transfer from the main heating element 21 to the inner bottom wall 122 is reduced, thereby increasing the heating amount of the aerosol generating rod 600 through the second cup wall 12. This can correspondingly reduce the proportion of radiant heat directly radiated by the main heating element 21 to the aerosol generating rod 600. When it is necessary to increase the radiant heat directly radiated by the heating element 2 to the aerosol generating rod 600, a heat-conducting element 23 can be provided on the surface of the main heating element 21 facing the insertion port 14, such as... Figure 7 In the example above, when the main heating element 21 is heating, the heat-conducting element 23 promotes the direct radiant heat from the main heating element 21 to the aerosol generating rod 600, which can correspondingly reduce the proportion of heat transferred from the main heating element 21 to the aerosol generating rod 600 through the second cup wall 12. When the heating assembly 100 is applied in an aerosol generating device, the above settings can be used to adjust the ratio between the direct radiant heat from the heating element 2 to the aerosol generating rod 600 and the heat conducted through the second cup wall 12 according to the different heating requirements of different types of aerosol generating rods 600. This ensures that the overall heating of the aerosol generating rod 600 matches its type, thereby improving the heating atomization efficiency, accelerating the aerosol generation speed, reducing user waiting time, and also improving the heat utilization efficiency and reducing energy waste.

[0059] In practical applications, the heat-conducting element 23 can specifically be a high thermal conductivity sheet, which can be any one or at least two of the following composite materials: graphite sheet, aluminum sheet, copper sheet, and silver sheet. Alternatively, it can be a high thermal conductivity ceramic sheet, such as alumina, silicon carbide, silicon nitride, beryllium oxide, or magnesium oxide. Carbon fiber cloth can also be used. Preferably, the heat-conducting element 23 can be selected from materials with strong infrared radiation characteristics, or a radiation layer enhancing infrared radiation characteristics can be coated on the surface of the heat-conducting element 23. Furthermore, the size of the heat-conducting element 23 can be appropriately set according to different heat transfer ratios.

[0060] In further embodiments of this application, such as Figure 8 and Figure 9As shown, the heating element 2 includes a main heating element 21 and a preheating layer 24. The main heating element 21 and the preheating layer 24 are stacked in a first direction, and the heat-conducting element 23 is located on any side surface of the main heating element 21 in the first direction, for example... Figure 8 In the example shown, the preheating layer 24 is located on the surface of the main heating element 21 facing the insertion port 14, or as... Figure 9 In the example shown, the preheating layer 24 is located on the surface of the main heating element 21 facing the inner bottom wall 122. The preheating layer 24 is a thermally conductive structure with a porous structure, allowing gas to pass through and be heated by the porous structure, achieving a preheating effect. The gas flows out of the porous structure and then into the aerosol generating rod 600. Compared to lower-temperature gas directly flowing into the aerosol generating rod 600, the preheated gas has a relatively higher temperature, which can offset the adverse effects of lower-temperature cold air entering the aerosol generating rod 600 on heating, further enhancing the heating effect of the aerosol generating rod 600. Simultaneously, depending on the position of the preheating layer 24 on the main heating element 21, the ratio between the heat transferred by the main heating element 21 through the second cup wall 12 and the heat radiated directly to the aerosol generating rod 600 can be adjusted.

[0061] In practical applications, the preheating layer 24 can be positioned on the side of the main heating element 21 facing the inner bottom wall 122 or on the side facing the insertion port 14, depending on the application requirements. Alternatively, preheating layers 24 can be positioned on both sides of the main heating element 21 simultaneously. The porous structure can be honeycomb-shaped, round, square, or other polygonal pores, or irregular pores. The pores are open at both ends to allow gas inflow and outflow. Depending on the preheating requirements, pores of appropriate diameter and length can be provided to ensure sufficient preheating of the gas to reach the target preheating temperature. Preferably, the preheating layer 24 can be made of porous metal, metal felt, porous ceramic, ceramic felt, or other structural forms.

[0062] Furthermore, in a specific example, the main heating element 21 can adopt any one of a sheet structure, a mesh structure, or a filament structure.

[0063] Furthermore, in one specific example, the surface of the main heating element 21 has an insulating layer.

[0064] Specifically, the main heating element 21 can be a metal-ceramic heating element (MCH heating element), a stainless steel thick-film heating element, or a ceramic thick-film heating element prepared by high-temperature co-fired ceramic process (HTCC). It can also be a surface-insulated heating mesh or heating wire, or a ceramic sheet with a heating mesh bonded to the surface, indium tin oxide (ITO) coated transparent conductive glass, or other transparent conductive oxide coated transparent conductive glass. Among them, the stainless steel thick-film heating element is made by sequentially printing and sintering an insulating thick-film layer, a thick-film heating layer, a thick-film electrode layer, and a thick-film protective layer on stainless steel material; the ceramic thick-film heating element is made by sequentially printing and sintering a thick-film heating layer, a thick-film electrode layer, and a thick-film protective layer on ceramic material, and is different from the high-temperature co-fired ceramic process (HTCC); in the surface-insulated heating mesh or heating wire, the surface insulation can be coating insulation or insulation with an insulating sheet. The insulating sheet can be a ceramic sheet, a mica sheet, or a glass sheet. The heating wire can be made of pure titanium, titanium alloy, iron-chromium-aluminum alloy, nickel-chromium alloy, iron-nickel alloy, SUS316 stainless steel, etc.

[0065] In further embodiments of this application, such as Figure 1 , Figure 3 , Figure 10 As shown, the heating element 2 has at least two pin structures 211 for connecting to the power supply component. The pin structures 211 can employ different wiring methods depending on the specific requirements. For example, in one specific example, such as... Figure 1 In the example shown, at least two pin structures 211 extend from the insertion port 14 outside the heating cavity 123 for electrical connection to the power supply component; the surfaces of the pin structures 211 each have an insulating layer to provide insulation and prevent short circuits from contacting the heating cup 1 or other structures. In another specific example, such as Figure 10 In the example, among at least two pin structures 211, one pin structure 211 is connected to the second cup wall 12 (specifically, it can be connected to the inner side wall 121 or the inner bottom wall 122). Correspondingly, the heating cup 1 is a conductive structure, and an electrical connection structure 111 is provided on the outer surface of the first cup wall 11 of the heating cup 1. The pin structure 211 connected to the second cup wall 12 forms an integral conductive structure with the heating cup 1 and the electrical connection structure, which can be used as one of the positive and negative terminals when connected to the power supply component, while the pin structure 211 extending from the insertion port 14 serves as the other of the positive or negative terminals. The pin structure 211 extending from the insertion port 14 is not limited to... Figure 1 The straight extension along the first direction shown can also be configured to extend along a curve to the insertion port 14 as needed, such as a spiral extension; furthermore, the pin structure 211 is not limited to... Figure 1 and Figure 10The two shown can also be set to more than two other quantities. For example, when the heating element 2 adopts a segmented heating structure, each heating segment can be set with an independent pin structure 211, or adjacent heating segments can share one of the pin structures 211.

[0066] Furthermore, in a specific example, such as Figure 1 , Figure 3 and Figure 11 As shown, in the heating chamber 123, a groove 1211 for passing through the wire is formed on the inner sidewall 121 of the second cup wall 12, such as... Figure 11 In the example, a wire-passing groove 1211 is provided on the third-direction side of the heating cavity 123. The opening of the wire-passing groove 1211 faces into the heating cavity 123, and the wire-passing groove 1211 extends along the first direction to the insertion port 14 and communicates with the insertion port 14. At least one pin structure 211 of the heating element 2 is provided in the wire-passing groove 1211 and extends to protrude from the insertion port 14. On a plane perpendicular to the first direction, such as Figure 11 As shown, the pin structure 211 is located between the second cup wall 12 and the first cup wall 11 to reserve sufficient assembly space for the aerosol generating rod 600. When the aerosol generating rod 600 is inserted into the heating chamber 123, the pin structure 211 will not interfere with the aerosol generating rod 600.

[0067] It should be noted that the wire guide groove 1211 is not limited to Figure 11 The rectangular groove shown can also be configured as an arc-shaped groove, a triangular groove, a trapezoidal groove, or other shaped groove structures; the wire guide groove 1211 is also not limited to... Figure 1 The structure shown extends in a straight line along the first direction, but it can also be set to extend along a curve according to actual needs.

[0068] In further embodiments of this application, such as Figure 12 , Figure 13 In the example, in a plane perpendicular to the first direction, this plane includes a second direction and a third direction that are perpendicular to each other. The maximum dimension of the heating cavity 123 in the third direction is greater than the maximum dimension in the second direction. Since the aerosol generating rod 600 is a cylindrical structure, when the aerosol generating rod 600 is inserted into the heating cavity 123, a side gap 1234 is formed between the heating cavity 123 and the outer wall of the aerosol generating rod 600 on at least one side in the third direction. Among the at least two pin structures 211 of the heating element 2, the pin structure 211 extending from the insertion port 14 is disposed within the side gap 1234 to utilize the side gap 1234 as a wiring channel for the pin structure 211. The side gap 1234 can be formed on both sides of the aerosol generating rod 600 in the third direction, for example... Figure 12The example in the text can also be found only in some forming side gaps 1234 of the aerosol generating rod 600 in the third direction, for example... Figure 13 Examples are provided. Additionally, the dimensions of the heating chamber 123 in the second direction are adapted to the diameter of the aerosol generating rod 600 to limit the aerosol generating rod 600. For example, the aerosol generating rod 600 may abut against the inner wall 121 of the heating chamber 123 in the second direction, or form a small gap.

[0069] Furthermore, in a specific example, such as Figures 1 to 11 In the example, the heating chamber 123 of the heating cup 1 can be cylindrical to fit the cylindrical structure of the aerosol generating rod 600. Specifically, a cavity can be formed on the inner wall 121 of the heating chamber 123, such as... Figure 11 The guide groove 1211 shown is for the pin structure 211 to pass through. In another specific example, such as Figure 12 and Figure 13 In the example, the heating chamber 123 of the heating cup 1 can also be an elliptical cylindrical cavity, so that when the aerosol generating rod 600 is inserted into the heating chamber 123, a side gap 1234 can be formed in the third direction for the pin structure 211 to pass through, while the arc-shaped inner sidewall 121 of the heating chamber 123 in the second direction can be used to limit the aerosol generating rod 600.

[0070] Furthermore, such as Figures 1 to 3 As shown, the support member 124 is specifically a heat-conducting structure, capable of conducting heat from the heating element 2, so that some of the heat is conducted through the support member 124 to the aerosol generating rod 600, which is beneficial to further enhance the heating effect. The support member 124 has a through-hole 1241 extending along the first direction, through which the pin structure 211 of the heating element 2 can pass, thus avoiding obstruction or interference from the support member 124 on the pin structure 211, reducing bending of the pin structure 211, and simplifying the wiring path of the pin structure 211.

[0071] Specifically, the support member 124 can be adopted as follows: Figures 1 to 3 The annular structure shown is adapted to fit the shape of the heating chamber 123 and the aerosol generating rod 600. The wire opening 1241 can be an integrally disassembled structure provided on the support member 124, such as... Figure 3 The state shown in the figure; of course, the wire opening 1241 can also be a groove structure opened on the support member 124.

[0072] Furthermore, in another specific example, such as Figure 14In the example, the support member 124 can also adopt a structure that is spaced apart in the circumferential direction. For example, the support member 124 includes a plurality of support blocks that are spaced apart in the circumferential direction of the heating chamber 123 and can abut against the aerosol generating rod 600. At the same time, the pin structure 211 of the heating element 2 can pass through the space between two adjacent support blocks to avoid the support blocks interfering with or blocking the pin structure 211.

[0073] In further embodiments of this application, such as Figure 1 and Figure 2 As shown, within the heating chamber 123, a snap-fit ​​structure 1212 is provided on the inner sidewall 121 of the second cup wall 12, opposite to the support member 124. The support member 124 is arranged circumferentially, and at least a portion of the support member 124 is snap-fitted and fixed to the snap-fit ​​structure 1212 to keep the support member 124 stable. Preferably, the snap-fit ​​structure 1212 can be as follows: Figure 2 The slot structure shown in the figure allows at least a portion of the support member 124 to be engaged in the slot structure for fixation. Of course, the engagement structure 1212 is not limited to... Figure 2 The slot structure can also adopt clamps, hooks, buckles, or other structural forms, which can be set according to actual usage needs.

[0074] In a further embodiment of this application, at least a portion of the heating element 2 can abut against the inner sidewall 121 of the heating cup 1, so that the heating element 2 can directly conduct heat between itself and the inner sidewall 121 in the lateral direction, thereby increasing the heat conduction coverage area of ​​the heating element 2 and further enhancing its heat conduction performance.

[0075] In further embodiments of this application, such as Figure 1 In the example, the heating cup 1 specifically adopts a metal structure so that the second cup wall 12 of the heating cup 1 forms a heat-conducting structure. The metal structure has strong thermal conductivity, enabling rapid heat transfer from the inner bottom wall 122 to the inner side wall 121. Furthermore, the metal structure has high strength, allowing it to be welded to other supporting structures when assembled in the aerosol generating device. Because a vacuum insulation cavity 13 exists between the first cup wall 11 and the second cup wall 12 of the heating cup 1, the temperature of the first cup wall 11 is lower, allowing it to be connected and assembled with plastic parts (including but not limited to in-mold injection molding, glue fixing, etc.) to fix the heating cup 1 to the base within the aerosol generating device (fixing methods include but are not limited to snap-fitting, glue fixing, etc.).

[0076] Furthermore, in the metal-structured heating cup 1, the wall thickness of both the first cup wall 11 and the second cup wall 12 can be relatively small, for example, less than 0.1 mm, forming an ultra-thin structure. This reduces the overall weight of the heating cup 1 while still meeting the corresponding strength requirements. The specific material of the heating cup 1 includes, but is not limited to, stainless steel, and other metal materials can also be used. Preferably, the inner wall surface of the vacuum insulation cavity 13 can be coated with an infrared reflective layer (e.g., a silver plating layer) to reflect infrared radiation, further enhancing the heat insulation effect and reducing the outward loss of radiant heat.

[0077] Of course, the heating cup 1 can also be made of different materials, such as ceramic material with good thermal conductivity, which will not be elaborated here.

[0078] An embodiment of the second aspect of this application provides an aerosol generating apparatus 500, such as... Figure 1 , Figure 15 , Figure 16 As shown, the aerosol generating device 500 includes a main housing 510, a heating component 100 as described in any of the embodiments of the first aspect, and a power supply component 520. The main housing 510 has an assembly port 511 at one end in the first direction. The heating component 100 is disposed within the main housing 510, and the insertion port 14 of the heating cup 1 of the heating component 100 corresponds to and communicates with the assembly port 511 of the main housing 510. The aerosol generating rod 600 can pass through the assembly port 511 and the insertion port 14 and be inserted into the heating chamber 123 of the heating cup 1. The power supply component 520 is electrically connected to the heating element 2 of the heating component 100 to supply power to the heating element 2, so that the heating element 2 heats up when energized, thereby heating the aerosol generating rod 600 inserted into the heating chamber 123 to generate aerosol. The power supply component 520 can be configured as follows: Figure 16 The aerosol generating device 500 is shown to be installed inside the main housing 510. Of course, the power supply component 520 can also be installed outside the main housing 510 and connected to the main housing 510 through a corresponding connection structure to form the complete unit.

[0079] The following describes a specific example of the aerosol generating apparatus 500 of this application with reference to the accompanying drawings.

[0080] like Figures 15 to 16 As shown, the aerosol generating device 500 is specifically a heating non-combustible device. For ease of description, the height direction of the aerosol generating device 500 is taken as the first direction, the width direction of the aerosol generating device 500 is taken as the second direction, and the thickness direction of the aerosol generating device 500 is taken as the third direction.

[0081] like Figures 15 to 16In the example, the main housing 510 has a bracket structure 512 inside, which is disposed opposite to the assembly port 511 and the heating assembly 100 in a first direction; the bottom of the heating assembly 100 is connected and fixed to the mounting base at the top of the bracket structure 512, and the side of the heating assembly 100 in the circumferential direction is limited by a limiting structure inside the main housing 510.

[0082] like Figures 1 to 3 In the example, the heating assembly 100 includes a heating cup 1, a heating element 2, and a support 124. The heating cup 1 is a hollow cylindrical structure made of stainless steel. The heating cup 1 includes a first cup wall 11 and a second cup wall 12 connected to each other. The first cup wall 11 is located on the outer side, and the second cup wall 12 is located on the inner side of the first cup wall 11. The wall thickness of both the first cup wall 11 and the second cup wall 12 is less than 0.1 mm. A vacuum insulation cavity 13 is formed between the first cup wall 11 and the second cup wall 12. The second cup wall 12 includes an inner side wall 121 and an inner bottom wall 122 connected to each other, and the inner side wall 121 and the inner bottom wall 122 form a cylindrical heating cavity 123. The heating cavity 123 has a through insertion port 14 at the end away from the inner bottom wall 122 in a first direction. The inner side wall 121 has a wire-passing groove 1211 extending in the first direction on the third direction side, and the wire-passing groove 1211 communicates with the insertion port 14.

[0083] The heating cavity 123 includes a first heating section 1231 and a second heating section 1232 connected sequentially in a first direction. The first heating section 1231 is located inside the heating cavity 123 near the insertion port 14, and the second heating section 1232 is located inside the heating cavity 123 near the inner bottom wall 122. The ends of the first heating section 1231 and the second heating section 1232 facing the insertion port 14 are connected. At the connection between the first heating section 1231 and the second heating section 1232, the inner sidewall 121 has a snap-fit ​​structure 1212, which is specifically an annular snap-fit ​​groove structure. The support member 124 is specifically an annular snap-fit ​​spring and is a heat-conducting structure. The support member 124 is arranged circumferentially and snapped into the snap-fit ​​groove structure. A wire-passing opening 1241 is opened on the support member 124 at a position corresponding to the wire-passing groove 1211. The heating element 2 is a circular sheet structure and is disposed within the second heating section 1232. In the first direction, one side of the heating element 2 abuts against the inner bottom wall 122 of the second cup wall 12, and the other side of the heating element 2 abuts against the support member 124, so that the support member 124 and the inner bottom wall 122 clamp the two sides of the heating element 2 to keep the heating element 2 fixed. In the first direction, there is a preset distance 'a' between the heating element 2 and the first heating section 1231. When the aerosol generating rod 600 is inserted into the heating chamber 123, the end face of the inserted end of the aerosol generating rod 600 abuts against the support member 124 to support the aerosol generating rod 600, and the distance between the end face of the aerosol generating rod 600 and the heating element 2 is not less than the preset distance 'a'.

[0084] Depending on the specific heating requirements, the heating element 2 can adopt different structural forms. For example, Figure 4 , Figure 5 For example, the heating element 2 includes a main heating element 21 and a heat insulation element 22. Both the main heating element 21 and the heat insulation element 22 are circular sheet-like structures and are stacked in a first direction. The heat insulation element 22 is located on any side surface of the main heating element 21 in the first direction. The thermal conductivity of the heat insulation element 22 is less than that of air, and it is used to reduce the heat transfer of the main heating element 21 on the side facing the heat insulation element 22. Or, as Figure 6 , Figure 7 In the example, the heating element 2 includes a main heating element 21 and a heat-conducting element 23. Both the main heating element 21 and the heat insulation element 22 are circular sheet-like structures, stacked in a first direction. The heat-conducting element 23 is located on either side of the main heating element 21 in the first direction. The thermal conductivity of the heat-conducting element 23 is greater than that of air, used to increase the heat transfer of the main heating element 21 on the side adjacent to the heat-conducting element 23. Alternatively, as... Figure 8 , Figure 9In the example, the heating element 2 includes a main heating body 21 and a preheating layer 24. Both the main heating body 21 and the preheating layer 24 are circular sheet structures. The preheating layer 24 is located on any side surface of the main heating body 21 in the first direction, and the preheating layer 24 has a porous structure that allows airflow to pass through, so as to preheat the airflow passing through the preheating layer 24 when the heating element 2 is heating. Through the structural arrangement of the heating element 2 in the above example, depending on the different usage requirements, any one of the following can be provided: heat insulation element 22, heat conduction element 23, or preheating layer 24, or two of them can be provided simultaneously (for example, heat insulation element 22 is provided on one side of the main heating element 21 and heat conduction element 23 is provided on the other side, or preheating layer 24 is provided on one side of the main heating element 21 and heat insulation element 22 or heat conduction element 23 is provided on the other side). This will increase or decrease the heat transfer of the main heating element 21 on the corresponding side, thereby changing the ratio between the heat transfer of the heating element 2 through the second cup wall 12 and the heat radiated directly from the heating element 2 to the aerosol generating rod 600, so as to meet the specific heating requirements of the aerosol generating rod 600.

[0085] Specifically, the support 124 is a heat-conducting structure. When the heating element 2 heats up, it can also conduct some heat to the aerosol generating rod 600 through the support 124 to further enhance the heating effect.

[0086] like Figure 1 , Figure 3 as well as Figure 11 In the example, the main heating element 21 of the heating element 2 is connected to two pin structures 211. The two pin structures 211 pass through the wire opening 1241 of the support member 124 and extend into the wire groove 1211 of the inner sidewall 121. The pin structures 211 extend along the first direction and both extend out of the heating cavity 123 through the insertion port 14. The surface of the pin structures 211 has an insulating layer to provide insulation.

[0087] like Figure 16 In the example, the power supply assembly 520 includes a battery and a control board electrically connected to the battery; the electrodes of the battery are electrically connected to two pin structures 211 to supply power to the main heating element 21 of the heating element 2; the control board is used to control the power supply status of the battery.

[0088] like Figure 11In the example, the diameter of the aerosol generating rod 600 is matched with the inner diameter of the heating chamber 123. When the aerosol generating rod 600 is inserted into the heating chamber 123, there is a certain gap between the inner wall 121 and the aerosol generating rod 600 in the radial direction. External air can flow into this gap through the assembly port 511 and the insertion port 14, and then flow to the insertion end of the aerosol generating rod 600. When the user performs a suction action, the atomizing matrix inside the aerosol generating rod 600 is heated and atomized to generate aerosol. The airflow in the heating chamber 123 is drawn into the aerosol generating rod 600 under negative pressure and mixes with the aerosol to form an aerosol mixed gas, which flows to the suction end of the aerosol generating rod 600.

[0089] The vacuum insulation cavity 13 of the heating cup 1 completely encloses the circumference and bottom of the heating cavity 123, thereby reducing the heat loss from the heating cavity 123.

[0090] The aerosol generating device 500 in this embodiment, through structural improvements and optimizations, employs a heating cup 1 with a vacuum insulation cavity 13, located between the first cup wall 11 and the second cup wall 12 of the heating cup 1. This achieves a combination of the heating cavity 123 and the vacuum insulation cavity 13, eliminating the need for additional insulation structures, simplifying the overall structure, and increasing the heating coverage area. In use, the heating element 2 can transfer heat circumferentially to the aerosol generating rod through the inner wall of the heating cavity 123, and can also directly radiate heat to the aerosol generating rod 600 in the first direction, effectively enhancing the heating and atomization effect. Moreover, according to different heating requirements, corresponding heat-conducting elements 23, heat-insulating elements 22, or preheating layers 24 can be provided on the surface of the main heating element 21, thereby changing the ratio of heat transfer through the two methods to meet the corresponding heating requirements of the aerosol generating rod 600, resulting in better heating performance.

[0091] Furthermore, the aerosol generating device 500 in this embodiment also has all the beneficial effects of the heating component 100 in any of the above embodiments, which will not be repeated here.

[0092] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
