Description

Technical Field

[0001] This invention relates to the field of aerosol generation technology, and more specifically, to an aerosol generation apparatus. Background Technology

[0002] Currently, most tobacco products on the market are based on traditional cigarettes, especially in terms of the shape and form of the smokeable material, which relies heavily on traditional cigarette manufacturing processes. Therefore, current products typically use reconstituted tobacco (i.e., an aerosol-generating matrix) to form ordered or disordered strands, strips, or shreds. Related aerosol-generating devices include an aerosol-generating matrix and a heating element. The heating element is attached to the aerosol-generating matrix and conducts heat, concentrating the heat near the heating element. When the user smokes, the gaps between the reconstituted tobacco materials act as airflow channels, with the airflow flowing within the aerosol-generating matrix and carrying out the aerosols in the gaps. However, direct attachment between the heating element and the aerosol-generating matrix can easily lead to excessive carbonization and burning in the area near the heating element, while insufficient consumption occurs in areas further away from the heating element. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an aerosol generating device that enables all parts of the aerosol generating matrix to be consumed evenly, thereby avoiding waste caused by insufficient consumption of the aerosol generating matrix in certain areas.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The aerosol generating apparatus of the present invention includes: a mounting member having a receiving cavity inside; an aerosol generating matrix disposed within the receiving cavity; an airflow channel formed between the aerosol generating matrix and the inner wall surface of the receiving cavity and / or inside the aerosol generating matrix; and a heating device having a heating part disposed within the airflow channel, and at least a portion of the heating part being spaced apart from the aerosol generating matrix; the heating part extending in the extending direction of the airflow channel; or, there are multiple heating parts, and the multiple heating parts are spaced apart in the extending direction of the airflow channel.

[0006] In some embodiments, the airflow channel extends spirally into the receiving cavity about the central axis of the receiving cavity;

[0007] The airflow channel has a first vent and a second vent that communicate with the outside, and the first vent and the second vent are spaced apart in the inward and outward directions.

[0008] In some embodiments, the aerosol generating matrix is ​​strip-shaped and extends spirally into the cavity around the central axis of the cavity; the aerosol generating matrix and the inner wall of the cavity together form the airflow channel.

[0009] In some embodiments, there are two aerosol generating matrices, which are arranged opposite to each other in the axial direction of the receiving cavity;

[0010] Each of the aerosol-generating matrices includes:

[0011] Flat plate section;

[0012] The enclosure portion has one end disposed on the flat plate portion; the enclosure portion extends spirally into the receiving cavity around the central axis of the receiving cavity;

[0013] One end of one of the enclosure portions is connected to the other end of the other enclosure portion, so that the two aerosol generating matrices enclose and form the airflow channel.

[0014] In some embodiments, both the first vent and the second vent are disposed on the outer surface of the mounting member, the first vent extending axially through the receiving cavity to the inner end of the airflow channel; and the second vent extending radially through the receiving cavity to the outer end of the airflow channel.

[0015] In some embodiments, the heating device includes:

[0016] A first heat-conducting element, which is a heat-conducting structure; the first heat-conducting element extends in the extending direction of the airflow channel; the first heat-conducting element forms the heating part;

[0017] The first electric heating wire is disposed inside the first heat-conducting element.

[0018] In some embodiments, the heating device includes a pin portion for supplying electricity to the heating device;

[0019] The pin portion is disposed at the inner end of the first heat-conducting component and extends out of the first vent; or,

[0020] The pin portion is disposed at the outer end of the first heat-conducting component and extends through the second vent.

[0021] In some embodiments, the heating device includes:

[0022] A support plate, which is radially disposed within the airflow channel of the receiving cavity;

[0023] Multiple thermally conductive protrusions are disposed on the support plate and are all located within the airflow channel; the multiple thermally conductive protrusions are arranged radially spaced apart along the receiving cavity;

[0024] The second electric heating wire includes multiple heating segments, which are arranged one-to-one inside the multiple heat-conducting protrusions.

[0025] In some embodiments, the support plate and the plurality of heat-conducting protrusions are integrally formed;

[0026] The second electric heating wire further includes a connecting section disposed inside the support plate; the plurality of heating sections are all connected to the connecting section; the second electric heating wire is configured such that the heat output of the connecting section is less than the heat output of the heating section.

[0027] In some embodiments, the aerosol generating apparatus further includes:

[0030] A conductive structure is disposed within the housing; one end of the conductive structure is electrically connected to the power supply, and the other end of the conductive structure is electrically connected to the heating device, so that the power supply and the heating device are electrically connected.

[0031] The aerosol generating apparatus of the present invention has a heating element disposed within an airflow channel. At least a portion of the heating element is spaced apart from the aerosol generating matrix, so that the heating element heats the airflow within the airflow channel, thereby using the heated airflow to heat the aerosol generating matrix. This avoids direct contact between the heating element and the aerosol generating matrix, preventing excessive carbonization of the aerosol generating matrix. Furthermore, since the heating element extends along the extension direction of the airflow channel, or multiple heating elements are spaced apart along the extension direction of the airflow channel, the airflow can be continuously heated by the heating element as it flows through the airflow channel. This ensures that the aerosol generating matrix is ​​heated uniformly, and that all parts of the aerosol generating matrix are consumed evenly, avoiding waste caused by insufficient consumption of the aerosol generating matrix in certain areas.

Detailed Implementation

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] The aerosol generating apparatus of the present invention will now be described with reference to the accompanying drawings.

[0050] like Figures 1-12 As shown, the aerosol generating device of this embodiment includes an installation component 100, an aerosol generating matrix 200, and a heating device 300.

[0051] The mounting component 100 has a receiving cavity 110 inside, and the aerosol generating matrix 200 is disposed within the receiving cavity 110 so that the mounting component 100 surrounds and supports the aerosol generating matrix 200, thereby protecting the aerosol generating matrix 200. An airflow channel 210 is formed between the aerosol generating matrix 200 and the inner wall surface of the receiving cavity 110 and / or inside the aerosol generating matrix 200. That is, the airflow channel 210 is directly formed inside the aerosol generating matrix 200; or, the airflow channel 210 is formed by the aerosol generating matrix 200 and the inner wall surface of the receiving cavity 110.

[0052] The heating device 300 has a heating element 310 that can release heat to heat the airflow within the airflow channel 210. The heating element 310 is disposed within the airflow channel 210, and at least a portion of the heating element 310 is spaced apart from the aerosol generating matrix 200 to minimize the contact area between the heating element 310 and the aerosol generating matrix 200, thereby avoiding excessive carbonization and burning of the aerosol generating matrix 200 near the heating element 310.

[0053] The heating element 310 extends in the extending direction of the airflow channel 210. Alternatively, there may be multiple heating elements 310, which are spaced apart in the extending direction of the airflow channel 210. When airflow flows through the airflow channel 210, the heating device 300 can continuously heat the flowing airflow so that the airflow can heat the various parts of the aerosol generating matrix 200 more evenly, thereby ensuring that the aerosol generating matrix 200 in each region is fully consumed and reducing waste of the aerosol generating matrix 200.

[0054] Compared with related technologies, in the aerosol generating apparatus of this invention, the heating element 310 of the heating device 300 is disposed within the airflow channel 210. At least a portion of the heating element 310 is spaced apart from the aerosol generating matrix 200, so that the heating element 310 heats the airflow within the airflow channel 210, thereby using the heated airflow to heat the aerosol generating matrix 200. This avoids direct contact between the heating element 310 and the aerosol generating matrix 200, which could lead to excessive carbonization of the aerosol generating matrix 200. Furthermore, since the heating element 310 extends in the extending direction of the airflow channel 210, or multiple heating elements 310 are spaced apart along the extending direction of the airflow channel 210, the airflow can be continuously heated by the heating element 310 as it flows through the airflow channel 210. This ensures that the aerosol generating matrix 200 is heated uniformly, and that all parts of the aerosol generating matrix 200 are consumed evenly, avoiding waste caused by insufficient local consumption of the aerosol generating matrix 200.

[0055] Furthermore, since the heating element 310 can heat the aerosol generating matrix 200 by means of heat exchange in the extension direction of the airflow channel 210, the airflow can fully consume each part of the aerosol generating matrix 200, ensuring the flavor of the generated aerosol and improving the user's vaping experience.

[0056] In some embodiments, such as Figure 4 and Figure 5As shown, the airflow channel 210 extends spirally into the receiving cavity 110 around its central axis. Specifically, the mounting member 100 can be a hollow cylindrical structure. The airflow channel 210 has a first vent 211 and a second vent 212 communicating with the outside, and the first vent 211 and the second vent 212 are spaced apart in the inward and outward directions. Here, the inward and outward directions refer to the radial direction along the receiving cavity 110, with the side closer to the central axis being the inward side and the side farther from the central axis being the outward side. The heating element 310 of the heating device 300 is correspondingly disposed within the spirally extending airflow channel 210, and at least a portion of the heating element 310 is spaced apart from the aerosol generating matrix 200. Since the airflow channel 210 extends in a spiral direction, the heating element 310 can adaptively extend continuously in this spiral direction, or multiple heating elements 310 can be arranged at intervals in the spiral direction, so that the airflow can continuously and fully exchange heat with the heating element 310 during the flow along the spiral channel. The heated high-temperature airflow flows along a spiral path to generate aerosol on the matrix 200 surface.

[0057] In other words, because the airflow channel 210 extends spirally into the receiving cavity 110, and the first vent 211 and the second vent 212 are provided in the inward and outward directions, the airflow channel 210 can form a long spiral flow path for airflow. On the one hand, this prolongs the heat exchange time of the airflow in the aerosol generating matrix 200, ensuring that the airflow can be fully and uniformly heated by the heating element 310, thereby avoiding the problem of insufficient consumption in some areas of the aerosol generating matrix 200 due to uneven airflow temperature. On the other hand, by extending the airflow channel 210 spirally into the receiving cavity 110, while ensuring a long extension length, the axial dimension of the airflow channel 210 in the mounting member 100 is smaller, which helps to reduce the overall size of the aerosol generating device in this embodiment, making it easier for the user to hold and improving the user experience.

[0058] In some embodiments, the flow area of ​​the airflow channel 210 remains constant in its extending direction, i.e., the first airflow channel 210 is distributed in an Archimedean spiral. Keeping the flow area of ​​the first airflow channel 210 constant in its extending direction allows the airflow to reach all areas of the aerosol product evenly when flowing within the first airflow channel 210, enabling the aerosol product to generate aerosols uniformly and improving the consistency of the aerosol product performance in this embodiment.

[0059] In some embodiments, such as Figure 4 , Figure 5 as well as Figure 8As shown, the aerosol generating matrix 200 is strip-shaped and spirals into the cavity 110 around its central axis. The aerosol generating matrix 200 and the inner wall of the cavity 110 together form an airflow channel 210.

[0060] Specifically, the aerosol generating matrix 200 is constructed as a continuous strip made of aerosol generating material. The strip-shaped aerosol generating matrix 200 has two opposite ends in the axial direction of the mounting member 100, and these two ends of the aerosol generating matrix 200 are in contact with the inner wall surface of the receiving cavity 110, so that a spirally extending gap is formed between the aerosol generating matrix 200 and the inner wall surface of the receiving cavity 110, which constitutes the airflow channel 210.

[0061] By directly forming an airflow channel 210 between the strip-shaped aerosol generating matrix 200 and the receiving cavity 110, the strip-shaped aerosol generating matrix 200 provides a continuous and flat surface. When the airflow flows from the outside to the inside or from the inside to the outside across the surface of the aerosol generating matrix 200, the aerosol generating matrix 200 can be consumed layer by layer in the radial direction. Therefore, the utilization efficiency of the aerosol generating matrix 200 is improved, and the problems of insufficient consumption of the aerosol generating matrix 200 and excessive carbonization near the heating area are further solved, reducing the waste of the aerosol generating matrix 200.

[0062] In other embodiments, such as Figure 9 and Figure 11 As shown, there are two aerosol generating substrates 200, which are arranged opposite each other in the axial direction of the receiving cavity 110. Each aerosol generating substrate 200 includes a flat plate portion 220 and a surrounding wall portion 230. One end of the surrounding wall portion 230 is disposed on the flat plate portion 220; the surrounding wall portion 230 extends spirally into the receiving cavity 110 around the central axis of the receiving cavity 110. The other end of one surrounding wall portion 230 is connected to the other end of the other surrounding wall portion 230, so that the two aerosol generating substrates 200 enclose each other to form an airflow channel 210.

[0063] Specifically, each aerosol generating matrix 200 includes an integrally formed or fixedly connected flat plate portion 220 and a surrounding wall portion 230. The flat plate portion 220 is generally a radially extending plate-like structure, and the surrounding wall portion 230 extends axially from the inner surface of the flat plate portion 220, i.e., towards the other aerosol generating matrix 200. The surrounding wall portion 230 is a ribbon-like body coiled circumferentially within the receiving cavity 110 with the central axis as the helical center. The helical directions of the two aerosol generating matrices 200 are the same, and the helical parameters are matched, such as pitch and radial span. The other end of one surrounding wall portion 230 is connected to the other end of the other surrounding wall portion 230 in the middle region of the axial direction. For example, the other ends of the two surrounding wall portions 230 may be in direct contact with each other, or they may be fixedly connected by means of snap-fit ​​or adhesive, thereby connecting the two surrounding wall portions 230 into an integral helical wall surface. The inner surfaces of the two flat plates 220 and the strip structure connected by the two wall sections 230 together enclose a gap extending in a spiral direction, which constitutes the airflow channel 210.

[0064] In other words, the airflow channel 210 is formed by two opposing aerosol generating matrices 200 enclosing each other, so that the entire wall of the airflow channel 210 is composed of aerosol generating matrices 200, thereby increasing the contact area between the aerosol generating matrices 200 and the hot airflow, thus improving the release efficiency and uniformity of aerosols in the airflow channel 210.

[0065] In some other embodiments, the aerosol generating matrix 200 includes a flat plate portion 220 and a surrounding wall portion 230, one end of which is disposed on the flat plate portion 220, and the surrounding wall portion 230 extends spirally into the receiving cavity 110 around the central axis of the receiving cavity 110. There is one aerosol generating matrix 200, and an airflow channel 210 is formed between the surrounding wall portion 230, the flat plate portion 220, and the wall surface of the receiving cavity 110 of this single aerosol generating matrix 200.

[0066] In some embodiments, the aerosol generating matrix 200 can be prepared by first mixing particulate smoke material with an adhesive and then extruding it.

[0067] In some embodiments, both the first vent 211 and the second vent 212 are disposed on the outer surface of the mounting member 100. The first vent 211 extends axially through the receiving cavity 110 to the inner end of the airflow channel 210; the second vent 212 extends radially through the receiving cavity 110 to the outer end of the airflow channel 210. That is, airflow can enter the airflow channel 210 through the first vent 211 and then exit through the second vent 212, i.e., the first vent 211 is the air inlet and the second vent 212 is the air outlet; or, airflow can enter the airflow channel 210 through the second vent 212 and then exit through the first vent 211, i.e., the first vent 211 is the air outlet and the second vent 212 is the air inlet.

[0068] Specifically, the mounting member 100 has an outer surface, which is at least a portion of the external appearance of the mounting member 100. Both the first vent 211 and the second vent 212 are formed on this outer surface, allowing air intake and exhaust to communicate with the outside environment via the outer surface of the mounting member 100. The first vent 211 extends axially inward and directly connects to the radially inner end region of the airflow channel 210, i.e., the inner end of the airflow channel 210. In other words, the inner end of the airflow channel 210 is the portion of the airflow channel 210 extending along a spiral path to near the central axis. The second vent 212 extends radially inward and directly connects to the radially outer end region of the airflow channel 210, i.e., the outer end of the airflow channel 210. In other words, the outer end of the airflow channel 210 is the starting or ending portion of the airflow channel 210 extending along a spiral path to near the inner wall of the receiving cavity 110.

[0069] For example, such as Figure 9 As shown, when the airflow channel 210 is formed between the two aerosol generating substrates 200, a through hole is provided in the central region of the mounting member 100 and the central region of the flat plate portion 220 of the aerosol generating substrate 200. The through hole on the flat plate portion 220 communicates with the airflow channel 210, and the through hole of the mounting member 100 and the through hole of the flat plate portion 220 are correspondingly connected. Another through hole extending into the receiving cavity 110 is also provided on the outer peripheral wall of the mounting member 100. This other through hole communicates with the outer end opening of the airflow channel 210 formed by the two aerosol generating substrates 200.

[0070] For example, such as Figure 8 As shown, when the airflow channel 210 is formed between an aerosol generating matrix 200 and the mounting member 100, a through hole is provided in the central region of the mounting member 100, which directly communicates with the interior of the airflow channel 210. Another through hole is also provided on the outer peripheral wall of the mounting member 100, extending into the receiving cavity 110, and this other through hole communicates with the opening of the airflow channel 210 near the inner peripheral wall of the receiving cavity 110.

[0071] Based on the above embodiments, since the extension direction of the first vent 211 is along the axial direction of the receiving cavity 110 and the extension direction of the second vent 212 is along the radial direction of the receiving cavity 110, the first vent 211 and the second vent 212 are perpendicular to each other, thereby preventing the debris of the aerosol generation matrix 200 from being discharged from the first vent 211 or the second vent 212, and improving the user's suction experience.

[0072] In some embodiments, such as Figure 7 As shown, the heating device 300 includes a first heat-conducting element 320 and a first electric heating wire. The first heat-conducting element 320 is a heat-conducting structure and extends in the extending direction of the airflow channel 210. The first heat-conducting element 320 forms a heating part 310, and the first electric heating wire is disposed inside the first heat-conducting element 320.

[0073] Specifically, the heating device 300 is used to heat the airflow flowing within the airflow channel 210. In this embodiment, the first heat-conducting element 320 is made of a material with good thermal conductivity, such as a metal or a high thermal conductivity ceramic material. The extension path of the first heat-conducting element 320 is generally consistent with the extension direction of the airflow channel 210. That is, when the airflow channel 210 extends in a spiral shape, the first heat-conducting element 320 is configured to be a spiral strip extending along the spiral direction in a corresponding manner. When the airflow channel 210 extends in a straight line along the axial direction, the first heat-conducting element 320 extends along that axial direction.

[0074] In the heating state, the first electric heating wire generates Joule heat through an external power source. The heat is conducted from the first electric heating wire to the first heat-conducting element 320, causing the entire first heat-conducting element 320 to heat up. When the airflow flows within the airflow channel 210 and passes over the outer surface of the first heat-conducting element 320, the airflow undergoes convective heat exchange with the first heat-conducting element 320, thus heating the airflow. Furthermore, since the first heat-conducting element 320 extends along the extension direction of the airflow channel 210, the airflow can be continuously heated.

[0075] By placing the first electric heating wire inside the first heat-conducting element 320, the first heat-conducting element 320 forms a heating part 310 that releases heat to the outside, thereby increasing the heat dissipation area of ​​the heating device 300. This allows the heat to be distributed more evenly in the extension direction of the airflow channel 210, avoiding the problem of excessively high local airflow temperature that may be caused by the electric heating wire directly heating the airflow. This is beneficial for uniformly heating all parts of the aerosol generation matrix 200.

[0076] In some embodiments, the heating device 300 includes a pin portion 330 for supplying electricity to the heating device 300. The pin portion 330 is an electrical connection portion of the heating device 300, used to supply electrical energy from an external power source to an electric heating element inside the heating device 300, such as the first electric heating wire in the above embodiments. The pin portion 330 is made of a conductive material, such as copper, is electrically connected to the corresponding end 341 of the first electric heating wire, and extends outward from inside the first heat-conducting member 320.

[0077] In some alternative embodiments, the pin portion 330 is disposed at the inner end of the first heat-conducting member 320 and extends through the first vent 211. The inner end of the first heat-conducting member 320 corresponds to the inner end region of the airflow channel 210. After the pin portion 330 is led out from the inner end of the first heat-conducting member 320, it extends outward along the axial direction of the receiving cavity 110, passes through the first vent 211, and extends to the outside of the mounting member 100. That is, the first vent 211 also serves as the lead-out channel for the pin portion 330.

[0078] In some alternative embodiments, the lead portion 330 is disposed at the outer end of the first heat-conducting element 320 and extends through the second vent 212. The outer end of the first heat-conducting element 320 corresponds to the outer end region of the airflow channel 210. After being led out from the outer end of the first heat-conducting element 320, the lead portion 330 extends radially outward along the receiving cavity 110, passes through the second vent 212, and extends to the outside of the mounting member 100. Similarly, the second vent 212 also serves as the lead-out channel for the lead portion 330.

[0079] Furthermore, such as Figure 8 As shown, a mounting groove 120 is provided on the outer peripheral wall of the mounting member 100 in the area corresponding to the second vent 212. A portion of the pin portion 330 is installed in the mounting groove 120, thereby making full use of the structure of the mounting member 100 so that the pin portion 330 is installed in the mounting member 100.

[0080] Furthermore, a sealant or insulating filler may be provided between the pin portion 330 and the wall surface of the first vent 211 or the second vent 212 to ensure airtightness and electrical safety. After the pin portion 330 protrudes from the first vent 211 or the second vent 212, the pin portion 330 can be electrically connected to the electrodes of an external power supply.

[0081] In other embodiments, such as Figures 9-12As shown, the heating device 300 includes a support plate 340, multiple heat-conducting protrusions 350, and a second electric heating wire. The support plate 340 is radially disposed within the airflow channel 210 of the receiving cavity 110. The multiple heat-conducting protrusions 350 are all disposed on the support plate 340 and are all located within the airflow channel 210; the multiple heat-conducting protrusions 350 are radially spaced apart from each other in the receiving cavity 110. The second electric heating wire includes multiple heating segments, which are correspondingly disposed within the multiple heat-conducting protrusions 350.

[0082] Specifically, the support plate 340 is a plate-shaped component whose main body extends radially along the receiving cavity 110 and passes through the airflow channel 210. The support plate 340 spans at least a portion of the cross-section of the airflow channel 210. The extension direction of the support plate 340 can be substantially parallel to the radial direction of the mounting cavity, or form a certain angle with the radial direction of the mounting cavity. The two ends of the support plate 340 are respectively fixed to the inner wall of the mounting component 100 and the corresponding part of the aerosol generating matrix 200, thereby achieving support and positioning for the entire heating device 300. The second electric heating wire is connected in series or in parallel among the multiple heat-conducting protrusions 350 through the wire portion passing through the inside of the support plate 340, and finally connected to the pin portion 330 to access an external power source. When powered on, the heat generated by each heating segment is conducted to its corresponding heat-conducting protrusion 350, causing each heat-conducting protrusion 350 to heat up and act as a heat source to heat the airflow.

[0083] In other words, multiple heat-conducting protrusions 350 form an array structure within the airflow channel 210, extending along the direction of the airflow channel 210, thereby increasing the heat exchange area of ​​the heating device 300. As the airflow passes through the multiple heat-conducting protrusions 350, the protrusions can disturb the airflow, further improving thermal efficiency.

[0084] Furthermore, such as Figure 5 As shown, the aerosol generating matrix 200 is provided with clearance grooves 240, and the support plate 340 passes through multiple clearance grooves 240 in sequence. The clearance grooves 240 are in contact with the outer surface of the support plate 340 to prevent airflow from leaking from the gap between the clearance grooves 240 and the outer surface of the support plate 340.

[0085] Furthermore, such as Figures 9-12As shown, the support plate 340 and multiple heat-conducting protrusions 350 are integrally formed. The second electric heating wire also includes a connecting section, which is disposed inside the support plate 340. Multiple heating segments are connected to the connecting section, and the second electric heating wire is configured such that the heat generation of the connecting section is less than that of the heating segments. Specifically, the connecting section is made of a different material than the heating segments, and the resistivity of the connecting section is lower than that of the heating segments; or, the connecting section and the heating segments are made of the same material, and the cross-sectional area of ​​the conductor in the connecting section is larger than that of the heating segments, so that the Joule heat generated by the connecting section when current flows is much less than that of the heating segments. Through the above embodiments, when the second electric heating wire is energized as a whole, heat is concentrated in the heating segments embedded inside the heat-conducting protrusions 350, while the connecting segments embedded inside the support plate 340 generate less heat, or even almost no heat.

[0086] In some embodiments, the aerosol generating apparatus of the present invention further includes a housing, a power supply, and a conductive structure, with the mounting component 100 disposed within the housing. The power supply, located within the housing, supplies power to the heating device 300. The conductive structure, also located within the housing, has one end electrically connected to the power supply and the other end electrically connected to the heating device 300, thereby enabling electrical conduction between the power supply and the heating device 300. The power supply can be a rechargeable secondary battery, such as a lithium-ion battery or a lithium polymer battery. A charging interface electrically connected to the power supply is also provided on or within the housing. The power supply and the heating device 300 are electrically connected via wires.

[0087] Furthermore, the aerosol generating device of this embodiment of the invention is also provided with a mouthpiece, and a suction channel is provided inside the mouthpiece. The outlet of the airflow channel 210 is connected to the suction channel of the mouthpiece.

[0088] In some alternative embodiments, such as Figure 1 As shown, a pin portion 330 is disposed at the inner end of the first heat-conducting element 320, and the pin portion 330 includes a first pin 331 and a second pin 332. The conductive structure includes a first conductive ring 610 and a second conductive ring 620, with the first conductive ring 610 disposed inside the second conductive ring 620. An insulating layer 630, such as a rubber layer, is disposed between the first conductive ring 610 and the second conductive ring 620. The first pin 331 and the second pin 332 are electrically connected to the first conductive ring 610 and the second conductive ring 620, respectively.

[0089] In other alternative embodiments, such as Figure 2As shown, the pin portion 330 is disposed at the outer end of the first heat-conducting element 320. The pin portion 330 includes a third pin 333 and a fourth pin 334, which are spaced apart axially in the receiving cavity 110. The conductive structure includes a third conductive ring 640 and a fourth conductive ring 650, both of which are sleeved on the outer side of the mounting member 100 and are spaced apart axially in the receiving cavity 110. The third conductive ring 640 presses the third pin 333 against the outer wall surface of the mounting member 100 and is electrically connected to the third pin 333. The fourth conductive ring 650 presses the fourth pin 334 against the outer wall surface of the mounting member 100 and is electrically connected to the fourth pin 334.

[0090] In some alternative embodiments, such as Figures 9-12 As shown, in the case where the heating device 300 includes a support plate 340, a plurality of heat-conducting protrusions 350, and a second electric heating wire, two opposing ends 341 of the support plate 340 extend out of the mounting member 100 along its length. These two ends 341 are made of a conductive material, such as copper. Specifically, these two ends 341 extend axially along the receiving cavity 110, wherein the two ends 341 may extend in the same direction along the axial direction of the receiving cavity 110, or they may extend in opposite directions along the axial direction of the receiving cavity 110. The two ends 341 of the support plate 340 can be connected to a power source via wires or conductive rings.
