Description

Technical Field

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

[0002] Currently, common heated non-combustible devices typically utilize built-in heating elements to heat an aerosol generating rod inserted into the device, causing the atomizing matrix inside the rod to generate aerosol. In devices employing circumferential heating, heating circuits are usually installed on the sidewall of a tubular heat-conducting structure. These circuits generate heat when energized, and the heat is then conducted to the aerosol generating rod through the tubular heat-conducting structure. However, in these heating methods, the heating circuits are generally fixed to the sidewall of the heat-conducting structure using printed circuitry. But due to the differences in materials and properties between the heating circuits and the heat-conducting structure, prolonged operation at high temperatures and the effects of thermal expansion and contraction can easily lead to localized stress. This can cause deformation or detachment of the connection between the heating circuits and the heat-conducting structure, affecting heat transfer stability and the overall heating effect.

[0036] 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. In some cases, certain operations related to the present application are not shown or described in the specification. 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.

[0037] 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.

[0038] 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).

[0039] An aerosol generating rod is an atomizing matrix carrier used in conjunction with an aerosol generating device. It stores an atomizing matrix and can be heated within the device to atomize the matrix and generate aerosols. To accommodate the insertion port of the aerosol generating device and the heating chamber of the heating component, the aerosol generating rod is typically a cylindrical rod-shaped structure.

[0040] When the heating component provided in this application is applied in an aerosol generating device, the pin structure of the heating element can be electrically connected to the power supply component. At the same time, the pin structure of the heating element is connected and fixed to the support component to form a support and fixation for the heating element. This replaces the technical solution of printing heating circuits on the heat-conducting structure in the existing equipment, so that the heating element does not depend on the heat-conducting structure. This helps the heating element release stress when thermal expansion and contraction occurs, and can effectively prevent the heating element from deforming or falling off, thereby reducing the impact on heat transfer stability and heating effect.

[0041] The following describes some embodiments of the heating component and aerosol generating device provided in this application with reference to the accompanying drawings. For ease of description, the height direction of the heating component and the aerosol generating device is taken as the first direction in the following embodiments.

[0042] 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 support assembly 1 and a heating element 2. The support assembly 1 has an assembly cavity 13, and the heating element 2 is disposed in the assembly cavity 13. In a first direction, one end of the support assembly 1 has an assembly port 111 communicating with the assembly cavity 13, so that the aerosol generating rod can pass through the assembly port 111 and enter the assembly cavity 13. The heating element 2 has at least one pin structure 22. When the heating assembly 100 is assembled in the aerosol generating device, it can form an electrical connection with the power supply assembly 420 through the pin structure 22, so that the heating element 2 heats up when energized, thereby heating the aerosol generating rod. The pin structure 22 is fixedly mounted on the support assembly 1 to fix the heating element 2 on the support assembly 1, thereby achieving support and fixation of the heating element 2.

[0043] It is understandable that heating elements commonly used in heated non-combustible aerosol generating equipment are usually made by printing heating circuits on the side wall of a heat-conducting pipe to fix the heating element. However, due to the differences in materials and performance between the two (such as differences in the coefficient of expansion), the heating element is not conducive to stress release when thermal expansion and contraction occurs. During long-term use, the heating element is prone to deformation or detachment, resulting in relatively poor stability.

[0044] The heating component 100 in this embodiment has been improved and optimized in structure. It can be connected and fixed to the support component 1 through the pin structure 22 of the heating element 2 to form a support and fixation for the heating element 2 without printing the connection on the heat-conducting structure. This helps the heating element 2 release stress when thermal expansion and contraction occurs, and can effectively prevent the heating element 2 from deforming or falling off, thereby reducing the impact on heat transfer stability and heating effect. At the same time, the connection and fixation is carried out by the pin structure 22 of the heating element 2 itself, without the need to set other fixing parts. The structure is relatively simple and easy to manufacture.

[0045] It should be noted that in practical applications, the structure of the heating element 2 can be set according to the usage requirements. The heating element 2 can directly heat the aerosol generating rod, or a corresponding heat-conducting element 3 can be set in the assembly cavity 13 according to the usage requirements. The heating element 2 contacts the heat-conducting element 3 and transfers heat to the aerosol generating rod through the heat-conducting element 3, without the need to fix the heating element 2 to the heat-conducting element 3. In addition, the number of pin structures 22 can be at least two, depending on the specific structure of the heating element 2; one or more parts can be set on a single pin structure 22 to be connected and fixed to the support component 1, depending on the specific structure of the support component 1.

[0046] In further embodiments of this application, such as Figure 1 , Figure 2 As shown, the support assembly 1 includes a first support member 11 and a second support member 12 connected to each other. The first support member 11 is a hollow structure and extends through the first direction. One end of the first support member 11 is an assembly port 111, and the other end is detachably connected to the second support member 12, so that the inner wall surfaces of the second support member 12 and the first support member 11 form an assembly cavity 13. A vent hole 121 is provided on the second support member 12, which extends through the second support member 12 in the first direction, so that external air can pass through the vent hole 121 and enter the assembly cavity 13. The lead structure 22 of the heating element 2 has a first end 221 and a second end 222 arranged opposite to each other. The first end 221 of the lead structure 22 is connected to the first support member 11, and the second end 222 of the lead structure 22 is connected to the second support member 12, so as to form multiple support points for the heating element 2, thereby enhancing the connection stability of the heating element 2.

[0047] It should be noted that the number of vents 121 can be one or more, and can be set according to the actual situation. When multiple vents 121 are provided, the multiple vents 121 can be arranged as follows: Figure 1 The arrangement shown is in a circular array, but other arrangements, such as a matrix, can also be used.

[0048] Furthermore, in a specific implementation, such as Figure 1 , Figure 2 In the example, the second support member 12 has a through electrical connection hole 122. The second end 222 of the pin structure 22 passes through the corresponding electrical connection hole 122 and extends to the outside of the assembly cavity 13. At the same time, the inner wall of the electrical connection hole 122 abuts against the side wall of the pin structure 22 that passes through the electrical connection hole 122, so as to fix and limit the pin structure 22. When the heating assembly 100 is assembled in the aerosol generating device, the second end 222 of the pin structure 22 is electrically connected to the power supply assembly 420, maintaining power supply while also fixing the second end 222 of the pin structure 22.

[0049] It should be noted that in the above embodiments, the electrical connection hole 122 can be a through hole extending along the first direction, for example... Figure 2 As shown in the diagram, the electrical connection hole 122 can also be configured as a through hole with a certain tilt angle or a through hole with a certain bending section or curved section, so as to increase the support force on the pin structure 22 in the first direction.

[0050] Furthermore, in another specific implementation, such as Figure 3 As shown, the second support member 12 has a through electrical connection hole 122, and the second end 222 of the pin structure 22 extends into the corresponding electrical connection hole 122; an electrical connector 123 is provided at the end of the electrical connection hole 122 away from the assembly cavity 13, and the second end 222 of the pin structure 22 abuts against the electrical connector 123. When the heating component 100 is assembled in the aerosol generating device, it can form an electrical connection with the power supply component 420 through the electrical connector 123, so the pin structure 22 does not need to extend outside the assembly cavity 13, and there is no need to reduce the wiring space, avoiding interference with other components in the aerosol generating device. The inner wall surface of the electrical connection hole 122 abuts against the side wall of the pin structure 22 that penetrates the electrical connection hole 122, so as to fix and limit the pin structure 22; the electrical connector 123 can support the second end 222 of the pin structure 22. In addition, the electrical connector 123 includes, but is not limited to, conductive posts and electrode plates.

[0051] It should be noted that in the above embodiments, the electrical connection hole 122 can be a through hole extending along the first direction, or the electrical connection hole 122 can be set as a through hole with a certain tilt angle or a through hole with a certain bending section or curved section, so as to increase the support force on the pin structure 22 in the first direction.

[0052] Furthermore, in a specific implementation, such as Figure 2 and Figure 3 In the example shown, a first protrusion structure 112 is provided on the inner wall of the first support member 11. The first protrusion structure 112 is specifically located near the assembly opening 111 and protrudes into the assembly cavity 13. A first fixing structure 1111 is provided at the end of the first protrusion structure 112 facing the heating element 2. The first fixing structure 1111 corresponds to the pin structure 22, and the first end 221 of the pin structure 22 is connected to the corresponding first fixing structure 1111 to fix and limit the first end 221 of the pin structure 22. Specifically, the first protrusion structure 112 can be a closed annular structure in the circumferential direction, such as... Figure 2 and Figure 3As shown in the diagram, the first protrusion structure 112 can also be configured as a discontinuous structure in the circumferential direction, such as one or more protrusion structures corresponding to the pin structure 22. The first fixing structure 1111 includes, but is not limited to, connecting holes, slots, and latches. By connecting the pin structure 22 to the first protrusion structure 112, the first end 221 of the pin structure 22 can extend along the first direction without bending, making assembly simple and convenient.

[0053] Furthermore, in another specific implementation, such as Figure 4 In the example, a second fixing structure 113 is provided on the inner wall of the first support member 11. The second fixing structure 113 is located near the assembly port 111, corresponding to the first end 221 of the pin structure 22. The first end 221 of the pin structure 22 is connected to the corresponding second fixing structure 113, thereby fixing and limiting the first end 221 of the pin structure 22 through the inner wall of the first support member 11. The first end 221 of the pin structure 22 can extend to the second fixing structure 113 by bending or tilting, such as... Figure 4 The state shown in the figure. Specifically, the second fixing structure 113 includes, but is not limited to, connecting holes, slots, and buckles. By setting the first end 221 of the pin structure 22 to be directly connected to the inner wall of the first support member 11, there is no need to set other structures in the assembly cavity 13, which simplifies the structure of the first support member 11 and facilitates processing and manufacturing.

[0054] In further embodiments of this application, such as Figure 5 , Figure 6 As shown, in the heating assembly 100, a heat-conducting component 3 is also provided in the assembly cavity 13. The heat-conducting component 3 is arranged corresponding to the assembly port 111 in the first direction. When the aerosol generating rod is inserted into the assembly cavity 13, the heat-conducting component 3 can cover at least part of the side wall of the aerosol generating rod. At the same time, the heat-conducting component 3 abuts against the heating element 2, and the heat generated by the heating element 2 can be conducted to the aerosol generating rod through the heat-conducting component 3, so as to expand the heat distribution range and enhance the heating effect through the heat-conducting component 3.

[0055] Specifically, the number of heat-conducting elements 3 can be one or more. When multiple heat-conducting elements 3 are provided, they can be arranged circumferentially in the assembly cavity 13, or in the first direction. Alternatively, multiple heat-conducting elements 3 can be arranged simultaneously in both the circumferential and first directions of the assembly cavity 13. The heat-conducting elements 3 can be made of materials with good thermal conductivity, and they are insulating structures or have an insulating coating on their surface, such as thermally conductive ceramics or metal materials with an insulating coating. This ensures that when the heating element 2 is energized and generates heat, the heat-conducting elements 3 remain in an insulating state and only serve a heat-conducting function. Preferably, the heat-conducting elements 3 can adopt an arc-shaped structure to match the shape of the aerosol generating rod.

[0056] Furthermore, in a specific implementation, such as Figure 5 , Figure 7 and Figure 8 As shown, a first protruding structure 112 is provided on the inner sidewall of the first support member 11 near the assembly opening 111, and the first protruding structure 112 protrudes into the inner side of the assembly cavity 13; correspondingly, a support groove 124 is provided at one end of the second support member 12 facing the assembly cavity 13, and the opening of the support groove 124 faces the heat conduction member 3. In the first direction, the end of the heat conduction member 3 away from the second support member 12 abuts against the first protruding structure 112, and the end of the heat conduction member 3 facing the second support member 12 is inserted into the support groove 124 and abuts against the support groove 124, thereby clamping both ends of the heat conduction member 3 through the first protruding structure 112 and the support groove 124 to support and fix the heat conduction member 3. The support trough 124 has a vent hole 121 on its bottom wall. When the aerosol generating rod is inserted into the assembly cavity 13, the end face of the aerosol generating rod is opposite to the bottom wall of the support trough 124, which shortens the distance between the vent hole 121 and the aerosol generating rod. The gas flowing in through the vent hole 121 can quickly enter the interior of the aerosol generating rod, so as to keep the airflow smooth during the suction process.

[0057] Furthermore, such as Figure 5 In the example, a first step structure 1112 can be provided on a section of the first protrusion structure 112 facing the heat conduction element 3, and a second step structure 1241 can be provided on the inner sidewall of the support groove 124, so that the two ends of the heat conduction element 3 in the first direction abut against the first step structure 1112 and the second step structure 1241 respectively, thereby providing support and limiting for the heat conduction element 3 in both the first direction and the lateral direction.

[0058] Furthermore, such as Figures 5 to 8 In the example shown, the heat-conducting element 3 is a closed structure extending circumferentially along the assembly cavity 13. Both ends of the heat-conducting element 3 are open in the first direction to allow the aerosol generating rod to pass through. The heat-conducting element 3 and the support groove 124 form a heating cavity 31. The end of the heating cavity 31 away from the support groove 124 is connected to the assembly port 111, allowing the aerosol generating rod to be inserted into the heating cavity 31 and heated. Furthermore, it provides complete circumferential coverage for the aerosol generating rod, resulting in more uniform heating in the circumferential direction. The heating cavity 31 can be a cylindrical cavity to match the shape of the aerosol generating rod, or it can be a cavity of other shapes, such as an elliptical cavity, depending on the application requirements. Additionally, the heat-conducting element 3 can be an integral cylindrical structure, for example... Figure 6 The example in the figure shows that the wall thickness of the heat-conducting element 3 is the same at any position in the circumferential direction, which can further improve the heating uniformity of the aerosol generating rod.

[0059] In further embodiments of this application, such as Figures 5 to 8 As shown, the heating element 2 specifically includes a heating base 21 and pin structures 22. The heating base 21 abuts against the outer wall of the heat-conducting element 3 so that the generated heat can be conducted to the heat-conducting element 3. The heating base 21 extends circumferentially along the assembly cavity 13 to cover at least part of the outer wall of the heat-conducting element 3, thereby increasing the contact area between the heating base 21 and the heat-conducting element 3 and improving the heat conduction efficiency. The pin structures 22 are connected to the side of the heating base 21 opposite to the heat-conducting element 3, and the number of pin structures 22 is at least two. In the circumferential direction of the assembly cavity 13, at least two pin structures 22 are spaced apart so that at least two pin structures 22 are distributed at different positions in the circumferential direction of the heating base 21 to form multi-point support for the heating base 21. This helps to reduce the torque generated by gravity on the heating base 21 and makes the force on the heating base 21 more uniform.

[0060] Furthermore, in a specific example, such as Figures 6 to 9 As shown, in the circumferential direction of the assembly cavity 13, the central angles corresponding to at least two pin structures 22 are in the range of 90° to 180°, thereby increasing the spacing between the pin structures 22 and making the force on the heating substrate 21 as uniform as possible. Preferably, when the central angle between two pin structures 22 is equal to 180°, the two pin structures 22 are located on opposite sides of the heating substrate 21. When there are multiple pin structures 22, multiple pin structures 22 can also be arranged at equal intervals along the circumference. For example, when three pin structures 22 are provided, the central angle between any two adjacent pin structures 22 can be set to 120°. Examples are not listed here.

[0061] Furthermore, in a specific implementation, such as Figures 6 to 8 As shown, the heating substrate 21 can be any one of heating circuit, heating mesh or heating sheet, and the shape of the heating substrate 21 is adapted to the heat-conducting element 3 so as to facilitate heat transfer through contact with the heat-conducting element 3.

[0062] In further embodiments of this application, such as Figure 2 , Figure 5 and Figure 6 In the example shown, both ends of the pin structure 22 extend along a straight line, such as the straight line along the first direction shown in the figure. This eliminates the need for bending the pin structure 22, making assembly more convenient. In practical applications, the pin structure 22 can also be set at a certain angle to the first direction, depending on the actual structural form.

[0063] Of course, in another specific implementation, at least a portion of the pin structure 22 can be set to extend along a curve, that is, the pin structure 22 includes at least a curved segment, for example, the pin structure 22 extends circumferentially in a spiral, or at least one end forms an arc segment; or, at least a portion of the pin structure 22 can be set to be a bent structure, for example... Figure 4 The first end 221 of the pin structure 22 is shown. The shape of the pin structure 22 can be set according to the specific structure of the support component 1 to meet the corresponding connection requirements.

[0064] In further embodiments of this application, such as Figure 10 and Figure 11 In the example, the heating assembly 100 may further include a third support 14 disposed within the first support 11 and located at the assembly port 111; the second support 12 has a plurality of contacts 141 on the side facing the assembly cavity 13, so that when the aerosol generating rod passes through the assembly port 111, the contacts 141 can abut against the side wall of the aerosol generating rod to fix and limit the aerosol generating rod. Preferably, as shown in the example, Figure 10 In the example, the third support 14 has a ring-shaped structure, and its size is adapted to the aerosol generating rod so that the aerosol generating rod can pass through the third support 14 and be inserted into the assembly cavity 13; the contact member 141 can have a flexible structure, capable of undergoing a certain deformation when in contact with the aerosol generating rod. Furthermore, the third support 14 can be made entirely of silicone.

[0065] An embodiment of the second aspect of this application provides an aerosol generating device 400, such as... Figure 12 , Figure 13 and Figure 14 As shown, the aerosol generating device 400 includes a main housing 410, a heating component 100 as described in any of the embodiments of the first aspect, and a power supply component 420. The main housing 410 serves as the mounting base for the aerosol generating device 400, and both the heating component 100 and the power supply component 420 are disposed inside the main housing 410. In the first direction, one end of the main housing 410 has an insertion port 411, and the assembly port 111 of the heating component 100 is correspondingly provided with and connected to the insertion port 411. The aerosol generating rod 500 can pass through the insertion port 411 and the assembly port 111 and be inserted into the assembly cavity 13 of the heating component 100. The heating element 2 of the heating component 100 is located in the assembly cavity 13, and the power supply component 420 is electrically connected to the pin structure 22 of the heating element 2 to supply power to the heating element 2, so that the heating element 2 can generate heat in the energized state to heat the aerosol generating rod 500, causing the atomizing matrix inside to be heated and atomized, and generating aerosol.

[0066] In this embodiment of the aerosol generating device 400, the pin structure 22 of the heating element 2 not only serves as an electrical connection but also connects and fixes to the support component of the heating assembly 100, so that the heating element 2 is fixed on the support component 1. This allows the heating element 2 to be supported independently without needing to be fixed to the heat-conducting component 3. Therefore, in this embodiment, the heating element 2 of the heating assembly 100 can directly heat the aerosol generating rod 500, or, according to usage requirements, a corresponding heat-conducting component 3 can be provided in the assembly cavity 13. By setting the heating element 2 to abut against the heat-conducting component 3, the heat generated by the heating element 2 is transferred to the aerosol generating rod 500 through the heat-conducting component 3 to form heating.

[0067] The following describes a specific example of the aerosol generating apparatus 400 of this application with reference to the accompanying drawings.

[0068] like Figure 1 , Figure 2 as well as Figures 5 to 14 As shown, the aerosol generating device 400 is specifically a heated non-combustible device, including a main housing 410, a heating component 100, and a power supply component 420. The height direction of the main housing 410 is a first direction, and an insertion port 411 is provided at the top of the main housing 410 in the first direction. A support structure 431 is provided inside the main housing 410, which divides the internal space of the main housing 410 into upper and lower chambers. The heating component 100 is located in the upper chamber of the main housing 410, and the power supply component 420 is located in the lower chamber of the main housing 410.

[0069] like Figure 1 , Figure 2 As shown, the heating assembly 100 includes a support assembly 1, a heating element 2, and a heat-conducting element 3. The support assembly 1 includes a first support 11, a second support 12, and a third support 14. The first support 11 is a hollow cylindrical structure that extends through a first direction, with one end of the first support 11 serving as an assembly port 111. The second support 12 is detachably connected to the end of the first support 11 away from the assembly port 111. The second support 12 and the inner wall of the first support 11 form an assembly cavity 13, and the assembly port 111 communicates with the assembly cavity 13. The heating element 2 and the heat-conducting element 3 are both disposed within the assembly cavity 13.

[0070] Specifically, a first protruding structure 112 is provided on the inner wall of the first support member 11 near the assembly port 111. The first protruding structure 112 is annular and protrudes into the assembly cavity 13. In the first direction, a first fixing structure 1111 is provided at the bottom of the first protruding structure 112. The first fixing structure 1111 takes the form of a connecting hole, and the bottom of the first protruding structure 112 also has a first step structure 1112. A support groove 124 is provided at the top of the second support member 12. The opening of the support groove 124 faces upward and is positioned opposite to the assembly port 111, extending into the heat-conducting member 3 in the assembly cavity 13. The heat-conducting member 3 is cylindrical. In the first direction, the top of the heat-conducting member 3 abuts against the first step structure 1112 of the first protruding structure 112, and the bottom of the heat-conducting member 3 is inserted into the support groove 124 and abuts against the second step structure 1241, thereby clamping and fixing both ends of the heat-conducting member 3. The supporting groove 124 and the heat-conducting component 3 form a heating cavity 31. Multiple vent holes 121 are provided on the bottom wall of the supporting groove 124, which penetrate the second supporting component 12 along a first direction and communicate with the heating cavity 31. Multiple air guide holes 125 are provided on the outer circumferential edge of the second supporting component 12, which communicate with the assembly cavity 13. Furthermore, multiple air guide channels 1113 are provided circumferentially at the point where the first stepped structure 1112 abuts against the top of the heat-conducting component 3, connecting the assembly opening 111 and the area of ​​the assembly cavity 13 located outside the heating cavity 31.

[0071] like Figures 5 to 8 As shown, the heating element 2 specifically includes a heating base 21 and three pin structures 22. The heating base 21 is specifically in the form of a heating circuit, and can be made of a metal material, such as nickel 50 or titanium. The heating circuit is arranged in a serpentine pattern along the circumference of the heat-conducting element 3, forming a cylindrical structure. The heat-conducting element 3 is specifically made of thermally conductive ceramic or a metal material with an insulating coating. The heating base 21 abuts against the outer wall of the heat-conducting element 3 so that the generated heat can be conducted to the heat-conducting element 3. The three pin structures 22 are connected to the side of the heating base 21 opposite to the heat-conducting element 3, and are spaced apart along the circumference of the assembly cavity 13, such as... Figures 6 to 9 As shown, in the circumferential direction of the assembly cavity 13, the central angles corresponding to the two pin structures 22 are in the range of 90° to 180°. The heating substrate 21 is divided into two parallel heating segments, with the middle pin structure 22 serving as a common pin. When the common pin is energized with one of the pin structures 22, the corresponding heating segment heats up. When all three pin structures 22 are energized simultaneously, both heating segments heat up simultaneously.

[0072] like Figure 1 , Figure 2In the example, all three pin structures 22 extend linearly along a first direction, and each pin structure 22 has a first end 221 and a second end 222 disposed opposite to each other. The first end 221 of each pin structure 22 extends into a corresponding connection hole on the first protrusion structure 112; the second support member 12 has an electrical connection hole 122 extending along the first direction, and the second end 222 of each pin structure 22 passes through the corresponding electrical connection hole 122 and extends to the outside of the assembly cavity 13. At the same time, the inner wall surface of the electrical connection hole 122 abuts against the side wall of the pin structure 22 that passes through the electrical connection hole 122, so as to fix and limit the pin structure 22.

[0073] like Figure 13 and Figure 14 In the example shown, a sealing structure 432 is provided at the top of the support structure 431. The sealing structure 432 is sealed to the circumferential edge of the bottom end of the support assembly 1, and a sealed space is formed between the sealing structure 432 and the bottom surface of the second support member 12. When the aerosol generating rod 500 is inserted into the heating chamber 31 through the assembly cavity 13, as... Figure 13 In the example, air entering through the assembly port 111 can pass through the air guide channel 1113 into the assembly cavity 13 (the area outside the heating cavity 31). The airflow flows downward in the first direction and flows through the air guide hole 125 to the sealed space below the second support member 12. When the user performs a suction action, the airflow can pass through the vent hole 121 on the second support member 12 into the heating cavity 31 under the action of negative pressure and be sucked into the aerosol generating rod 500.

[0074] like Figure 13 and Figure 14 In the example, the power supply component 420 includes a battery 421 and an electronic control board 422 that are electrically connected; the second end 222 of the pin structure 22 passes through the sealing structure 432 and is electrically connected to the corresponding electrode of the battery 421, and the electronic control board 422 is used to control the power supply state of the battery 421.

[0075] like Figure 10 , Figure 11 as well as Figure 13 In the example, the third support 14 is located at the assembly port 111 of the first support 11 and at the top of the first protruding structure 112. Specifically, the third support 14 is a ring-shaped structure made of silicone, through which the aerosol generating rod 500 can pass and be inserted into the heating chamber 31. The inner side of the second support 12 is provided with a plurality of contact members 141 along the circumferential direction, so that when the aerosol generating rod 500 passes through the assembly port 111, the contact members 141 can abut against the side wall of the aerosol generating rod 500 to fix and limit the aerosol generating rod 500.

[0076] In this embodiment of the aerosol generation device, the heating element of the heating component is connected and fixed to the support component through a pin structure, so that the heating element is fixed on the support component. The heating element and the heat-conducting component 3 only need to contact the heat-conducting housing, without printing the heating element on the heat-conducting surface. This helps the heating element release stress when thermal expansion and contraction occur, effectively preventing the heating element from deforming or falling off. In long-term use, it can reduce the adverse effects on heat transfer stability and heating effect. At the same time, it simplifies the structure, making it easier to manufacture and assemble. In addition, the heating element has two parallel heating sections, which cover different areas around the heat-conducting component 3 respectively. It can be heated in sections or simultaneously according to specific usage needs, making the heating strategy more flexible and meeting the heating requirements of different stages in the suction process.

[0077] Furthermore, the aerosol generating device in this embodiment also has all the beneficial effects of the heating component in any of the above embodiments, which will not be repeated here.

[0078] 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.
