Description

Technical Field

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

[0002] Aerosol generating devices are small electronic devices that generate aerosols by heating an aerosol generating matrix using a non-combustible method. In related technologies, the aerosol generating matrix is ​​typically a columnar structure, with a heating element providing peripheral or central heating. However, due to the significant heat melting of the aerosol generating matrix, the time required for the matrix to atomize and escape is relatively long, reducing the user experience. Furthermore, traditional aerosol generating devices require frequent replacement of the aerosol generating matrix, further compromising the user experience. Summary of the Invention

[0003] This application provides a heating component and an aerosol generating apparatus.

[0004] The heating assembly of this application includes a chamber, a motion mechanism, and a heating element. The chamber is used to house a sheet-like aerosol generating matrix, which extends circumferentially along the chamber. The motion mechanism is movably connected to the chamber. The heating element is connected to the motion mechanism and disposed close to the surface of the aerosol generating matrix. The heating element is configured to move along a spiral trajectory relative to the aerosol generating matrix with the motion mechanism.

[0005] In the heating assembly of this application, the heating element heats the aerosol generating matrix while moving in a spiral motion relative to it. This allows the heating element to continuously move to unheated, fresh segments of the aerosol generating matrix during the heating process, thereby increasing the heating rate, accelerating aerosol escape, effectively shortening waiting time, and improving user experience. Furthermore, the changing relative position between the heating element and the aerosol generating matrix allows the heating element to heat relatively fresh aerosol generating matrix, increasing the effective number of aerosol generating matrix extractions, extending the usage time of a single aerosol generating matrix, and ultimately reducing the frequency of aerosol generating matrix replacement.

[0006] In some embodiments, the aerosol generating matrix extends circumferentially around the cabin and surrounds the cabin; and / or,

[0007] The aerosol generation matrix comprises multiple sub-matrix segments, which are arranged circumferentially along the cabin and spliced ​​together sequentially; and / or,

[0008] The aerosol generating matrix is ​​strip-shaped and spirally extended to form a cylindrical structure. The spiral extension path of the aerosol generating matrix matches the movement trajectory of the heating element.

[0009] In this way, the aerosol generating matrix surrounds the chamber, which can increase the heated area and further increase the number of suction cycles; multiple sub-matrix segments are arranged along the axial direction of the chamber and spliced ​​together in sequence, which can improve the structural stability of the aerosol generating matrix itself and ensure the reliability of relative motion; the aerosol generating matrix extends spirally along the movement trajectory of the heating element, which can improve the heating accuracy, reduce waste, and improve the aerosol generation efficiency.

[0010] In some embodiments, the motion mechanism includes a first motion mechanism and a second motion mechanism. The first motion mechanism is rotatably connected to the cabin, and the second motion mechanism is linked to the first motion mechanism and configured to move axially relative to the cabin as the first motion mechanism rotates.

[0011] The aerosol generating matrix is ​​fixedly connected to the first motion mechanism, and the heating element is fixedly connected to the second motion mechanism.

[0012] In this way, the aerosol generating matrix extends circumferentially along the cabin and rotates with the first motion mechanism, while the heating element moves axially along the cabin with the second motion mechanism, so that the heating element moves along a spiral trajectory relative to the aerosol generating matrix. This design makes the structure of the motion mechanism simpler, more compact, and more reliable.

[0013] In some embodiments, the first motion mechanism includes a base rotatably connected to the cabin and a rotating member fixedly connected to the base, the rotating member extending linearly along the axial direction of the cabin, and a second motion mechanism movably connected to the rotating member to move along the axial direction of the cabin while the rotating member rotates.

[0014] Thus, by rotating the base to the cabin, fixing the rotating component to the base, and movably connecting the second motion mechanism to the rotating component, the base can drive the rotating component to rotate relative to the cabin. When the rotating component rotates, it drives the second motion mechanism to move linearly along the axial direction relative to the cabin. As a result, the aerosol generating matrix rotates with the first motion mechanism relative to the cabin, and the heating element moves linearly along the axial direction relative to the cabin with the second motion mechanism. The structure is simple and the motion is highly reliable.

[0015] In some embodiments, the second motion mechanism includes a slider that is fixedly connected to the heating element and is sleeved on and movably connected to the rotating element.

[0016] Thus, by mounting the sliding component on the rotating component and movably connecting it to the sliding component, the sliding component can move linearly along the extension direction of the rotating component, that is, the axial direction of the cabin, while the rotating component rotates relative to the sliding component, thereby ensuring the stable and reliable linkage between the first motion mechanism and the second motion mechanism.

[0017] In some embodiments, the slider is formed with a mounting groove, and the end of the heating element is provided with a mounting seat, which is at least partially accommodated in the mounting groove.

[0018] Thus, by having the heating element at least partially accommodated in the mounting groove at its end, the heating element is fixedly connected to the mounting groove, thereby increasing the reliability of the connection between the heating element and the sliding component and helping to reduce the transfer of heat to the sliding component.

[0019] In some embodiments, the rotating element is located at the geometric center of the base, the base is rotatably arranged around the rotating element, and the rotating element and the heating element are located at the two ends of the sliding element along the radial direction of the cabin.

[0020] Thus, the sliding member extends radially from the rotating member towards the cabin wall, and the heating element is located at the end of the sliding member that is radially away from the rotating member. This makes the distance between the heating element and the aerosol generating matrix on the cabin wall relatively close. Furthermore, during the relative movement of the first motion mechanism and the second motion mechanism, the distance between the heating element and the aerosol generating matrix on the cabin wall remains relatively stable, which helps to ensure the consistency of heating.

[0021] In some embodiments, the heating assembly further includes a guide member, which is parallel to and spaced apart from the rotating member, and is slidably connected to the sliding member to limit the sliding direction of the sliding member.

[0022] Thus, by setting the guide and rotating parts parallel and spaced apart, and by sliding the guide and sliding parts together, the sliding parts are further restricted to move in a straight line along the direction of the guide and sliding parts, that is, along the axial direction of the cabin, thereby ensuring that the heating element and the aerosol generating device move relative to each other in a preset manner.

[0023] In some embodiments, the first motion mechanism further includes a support frame mounted on and fixedly connected to a base, and an aerosol generating matrix is ​​arranged around the support frame along the circumference of the cabin and covers at least a portion of the cabin wall.

[0024] Thus, by mounting the aerosol generating matrix on the base and fixing it to the base, the aerosol generating matrix is ​​arranged around the circumference of the cabin on the mounting, thereby fixing the aerosol generating matrix to the base. The mounting and the aerosol generating matrix can rotate synchronously with the base relative to the cabin wall.

[0025] In some embodiments, the cabin includes a top cover and a bulkhead, with the top cover and base facing each other along the axial direction of the cabin, the bulkhead surrounding the top cover and base circumferentially around the cabin, and a rotating member rotatably connected to the top cover at one end axially away from the base.

[0026] In this way, by having the top cover and base opposite each other along the axial direction of the cabin, and the cabin wall surrounding the top cover and base along the circumference of the cabin, and the rotating part rotatably connected to the top cover at the end away from the base along the axial direction, the balance of the rotating part during rotation is improved, thereby improving the structural stability and reliability of the motion mechanism, and ensuring that the heating element and the aerosol generating device generate relative motion in a preset manner.

[0027] In some embodiments, the heating assembly includes an isolation sleeve fitted inside the chamber, with a top cover closing onto the isolation sleeve. The isolation sleeve is used to isolate the rotating component from the aerosol generation matrix.

[0028] In this way, by installing the isolation sleeve inside the cabin and closing it with the top cover, the isolation sleeve isolates the rotating parts and the aerosol generation matrix, thereby reducing the aerosol contamination of the moving mechanism, extending the effective life of the moving mechanism, and also playing a certain role in limiting the aerosol generation matrix.

[0029] In some embodiments, the isolation sleeve includes a main body and a curved portion connected to the main body. The curvature of the main body matches the bulkhead of the cabin. The curved portion is recessed from the main body away from the bulkhead of the cabin towards the rotating member. The curved portion and the bulkhead of the cabin together define a heating channel, and the heating element extends at least partially into the heating channel.

[0030] Thus, the curved section and the bulkhead together define a heating channel, and the heating element extends at least partially into the heating channel, so that the aerosol generation matrix is ​​heated in the heating channel, which facilitates the flow of aerosols along the heating channel for inhalation.

[0031] In some embodiments, the heating assembly further includes a guide member movably connected to the second motion mechanism. The guide member is parallel to and spaced apart from the rotating member, and its two axial ends are fixedly connected to the top cover and the isolation sleeve, respectively.

[0032] In this way, by fixing the two ends of the guide member axially to the top cover and the isolation sleeve respectively, the structural stability of the guide member is improved, thereby ensuring that the sliding member and the heating element move in the direction defined by the guide member.

[0033] This application provides an aerosol generating device, which includes a housing and a heating component according to any of the above embodiments, with the chamber fixedly connected to the housing.

[0034] The aerosol generating apparatus of this application, through the spiral trajectory movement of the heating element in the heating component relative to the aerosol generating matrix, causes the heating element to continuously move to the fresh aerosol generating matrix for heating during the heating process. Furthermore, the aerosol generating matrix has a sheet-like structure, thereby increasing the aerosol escape rate, shortening the heating time, and improving the user experience. At the same time, it increases the effective suction times of the aerosol generating matrix, extends the usage time of a single aerosol generating matrix, and thus reduces the replacement frequency of the aerosol generating matrix.

[0035] In some embodiments, the aerosol generating device includes a drive member connected to a motion mechanism, the drive member being used to drive the motion mechanism to move relative to the housing.

[0036] In this way, the drive component is connected to the motion mechanism and drives the motion mechanism to move relative to the housing, thereby providing driving force for the relative motion of the aerosol generating matrix and the heating element, and making it easy to control the relative motion state of the aerosol generating matrix and the heating element through the drive component.

[0057] Please see Figure 1 and Figure 2 The aerosol generating device 1000 is a structure capable of generating aerosols by applying resistance heating, electromagnetic heating, microwave heating, or other methods to the aerosol generating matrix 11. The aerosol generating matrix 11 is a plant leaf product that has been processed and heated to produce aerosols. The aerosol generating matrix 11 can be in a fully solid or semi-solid state. The aerosol generating matrix 11 can be prepared using processes such as rolling, slurry preparation, die casting, and extrusion.

[0058] Aerosol generating matrix 11 is heated to form an aerosol. The aerosol can be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. Users can inhale the aerosol into their mouth, nasal cavity, or lungs through their mouth or nose. The aerosol inhaled into the user's respiratory system can be used for various purposes such as food, medicine, and health care.

[0059] Please see Figure 3 and Figure 4 The heating assembly 100 of this application includes a chamber 10, a motion mechanism 20, and a heating element 30. The chamber 10 is used to accommodate a sheet-like aerosol generating matrix 11. The aerosol generating matrix 11 extends circumferentially along the chamber 10. The motion mechanism 20 is movably connected to the chamber 10. The heating element 30 is connected to the motion mechanism 20 and disposed close to the surface of the aerosol generating matrix 11. The heating element 30 is configured to move along a spiral trajectory relative to the aerosol generating matrix 11 with the motion mechanism 20.

[0060] In the heating assembly 100 of this embodiment, the heating element 30 heats the aerosol generating matrix 11 while moving in a spiral motion relative to it. This allows the heating element 30 to continuously move to unheated, fresh segments of the aerosol generating matrix 11 during the heating process, thereby increasing the heating rate, accelerating aerosol escape, effectively shortening waiting time, and improving user experience. Furthermore, the changing relative position of the heating element 30 and the aerosol generating matrix 11 allows the heating element 30 to heat relatively fresh aerosol generating matrix 11, thereby increasing the effective number of aerosol generating matrix 11 extractions, extending the usage time of a single aerosol generating matrix 11, and ultimately reducing the replacement frequency of the aerosol generating matrix 11.

[0061] Specifically, in combination Figure 6 The chamber 10 can be a hollow cylindrical structure, and the aerosol generating matrix 11 is housed within the chamber 10. The cross-sectional shape of the aerosol generating matrix 11 matches the cross-sectional shape of the inner contour of the chamber 10. It should be noted that the cross-sections of the chamber 10 and the aerosol generating matrix 11 refer to the cross-sections perpendicular to the axial direction of the chamber 10.

[0062] For example, the cross-sectional shape of the inner contour of the hull 10 includes, but is not limited to, a circle, an ellipse, a triangle, a quadrilateral, a hexagon, a runway shape, or other irregular shapes. The inner and outer contours of the hull 10 can be the same or different. This application only uses the example of the inner and outer contours of the hull 10 being circular in cross-sectional shape for illustration.

[0063] The aerosol generating matrix 11 extends circumferentially along the chamber 10, meaning it extends along the periphery of the chamber 10 wall, and is not intended to limit the cross-sectional shape of the chamber 10. The geometric center of the cross-section of the aerosol generating matrix 11 may coincide with the geometric center of the cross-section of the chamber 10, that is, the aerosol generating matrix 11 and the chamber 10 are coaxial. For ease of explanation, unless otherwise specified, "axial," "radial," and "circumferential" in the embodiments of this application refer to the axial, radial, and circumferential directions of the chamber 10, respectively.

[0064] Optionally, the aerosol generating matrix 11 is fixed relative to the chamber 10. This can be achieved by the aerosol generating matrix 11 being applied, deposited, or fixed to the chamber wall 13 by fasteners. The motion mechanism 20 drives the heating element 30 to move relative to the chamber 10 along a spiral trajectory, so as to achieve the movement of the heating element 30 relative to the aerosol generating matrix 11 along a spiral trajectory.

[0065] Optionally, both the aerosol generating matrix 11 and the heating element 30 are movably arranged relative to the cabin 10. The relative motion coupling between the aerosol generating matrix 11 and the heating element 30 enables the heating element 30 to move along a spiral trajectory relative to the aerosol generating matrix 11. For example, the motion mechanism 20 can drive the heating element 30 to move linearly relative to the cabin 10, and the aerosol generating matrix 11 can be connected to the motion structure and rotate relative to the cabin 10.

[0066] In this embodiment, to facilitate the rotation of the aerosol generating matrix 11, both the aerosol generating matrix 11 and the chamber 10 can be rotating bodies. For example, both the chamber 10 and the aerosol generating matrix 11 can be cylindrical. Alternatively, the cross-sectional dimensions of the chamber 10 and the aerosol generating matrix 11 can vary regularly along the axial direction, and the chamber 10 can be funnel-shaped, conical, or have other various structures.

[0067] Optionally, the central axis of the spiral motion trajectory of the heating element 30 coincides with the central axis of the aerosol generating matrix 11.

[0068] Optionally, the aerosol generating matrix 11 and the heating element 30 can move relative to each inhalation of the user, so that the heating element 30 is opposite to and heats a section of fresh aerosol generating matrix 11. The relative movement of the aerosol generating matrix 11 and the heating element 30 can be stopped immediately to maintain the heating of that section of aerosol generating matrix 11. When the user inhales the next inhalation, the relative movement of the aerosol generating matrix 11 and the heating element 30 causes the heating element 30 to heat the next section of fresh aerosol generating matrix 11.

[0069] Optionally, the aerosol generating matrix 11 and the heating element 30 can continuously move relative to each inhalation by the user, and the heating element 30 continuously heats the aerosol generating matrix 11. In this way, the aerosol generating matrix 11 opposite to the heating element 30 is constantly changing, and the heating element 30 always heats a relatively fresh aerosol generating matrix 11.

[0070] Please see Figure 6 and Figure 9 In some embodiments, the aerosol generating matrix 11 extends circumferentially along the chamber 10 and surrounds the chamber 10; and / or,

[0071] The aerosol generating matrix 11 comprises multiple sub-matrix segments, which are arranged circumferentially along the chamber 10 and sequentially spliced ​​together; and / or,

[0072] The aerosol generating matrix 11 is strip-shaped and spirally extended to form a cylindrical structure. The spiral extension path of the aerosol generating matrix 11 matches the movement trajectory of the heating element 30.

[0073] Thus, the aerosol generating matrix 11 surrounds the chamber 10, increasing the heated area and further increasing the number of suction cycles; multiple sub-matrix segments are arranged along the axial direction of the chamber 10 and spliced ​​sequentially, which can improve the structural stability of the aerosol generating matrix 11 itself and ensure the reliability of relative motion; the aerosol generating matrix 11 extends spirally along the movement trajectory of the heating element 30, improving the heating accuracy, reducing waste, and improving the aerosol generation efficiency.

[0074] Optionally, the aerosol generating matrix 11 is a thin-walled hollow cylindrical structure housed within the chamber 10. The aerosol generating matrix 11 can be directly molded as a single cylindrical structure, or it can be formed by splicing together multiple arc-shaped thin-sheet sub-matrix segments to form a cylindrical structure.

[0075] Optionally, the aerosol generating matrix 11 is strip-shaped, with the width of the aerosol generating matrix 11 matching the dimensions of the opposite ends of the heating element 30. The aerosol generating matrix 11 extends spirally to form a cylindrical structure, which can be fitted inside the chamber 10. The spiral extension path of the aerosol generating matrix 11 matches the spiral motion trajectory of the heating element 30 relative to the aerosol generating matrix 11, ensuring that during relative motion, the surfaces of the heating element 30 and the aerosol generating matrix 11 remain relatively stable and aligned in a fixed direction.

[0076] Optionally, the aerosol generating matrix 11 may include multiple curved strip-shaped sub-matrix segments. The multiple sub-matrix segments are sequentially spliced ​​along a spiral path and spirally wrapped around the inner wall of the chamber 10 to form an integral cylindrical structure.

[0077] It should be noted that when the aerosol generating matrix 11 is formed by splicing multiple sub-matrix segments, the segment of the aerosol generating matrix 11 heated by the heating element 30 at each instant or time interval is a segment of the aerosol generating matrix 11 that is close to and facing the heating element 30 at the corresponding moment, and does not necessarily correspond one-to-one with the sub-matrix segments.

[0078] Please see Figure 8 and Figure 9 In some embodiments, the motion mechanism 20 includes a first motion mechanism 21 and a second motion mechanism 22. The first motion mechanism 21 is rotatably connected to the cabin 10, and the second motion mechanism 22 is linked to the first motion mechanism 21 and configured to move axially relative to the cabin 10 as the first motion mechanism 21 rotates.

[0079] The aerosol generating matrix 11 is fixedly connected to the first motion mechanism 21, and the heating element 30 is fixedly connected to the second motion mechanism 22.

[0080] Thus, the aerosol generating matrix 11 extends circumferentially along the chamber 10 and rotates with the first motion mechanism 21, while the heating element 30 moves axially along the chamber 10 with the second motion mechanism 22, causing the heating element 30 to move along a spiral trajectory relative to the aerosol generating matrix 11. This design makes the structure of the motion mechanism 20 simpler, more compact, and more reliable.

[0081] Specifically, the linkage between the second motion mechanism 22 and the first motion mechanism 21 means that when the first motion mechanism 21 rotates relative to the cabin 10, the first motion mechanism 21 drives the second motion mechanism 22 to move relative to the cabin 10.

[0082] The connection between the second motion mechanism 22 and the first motion mechanism 21 can form a revolute joint and a prismatic joint. The first motion mechanism 21 can rotate relative to the second motion mechanism 22, and the second motion mechanism 22 can also move relative to the first motion mechanism 21. The first motion mechanism 21 drives the aerosol generating matrix 11 to rotate relative to the chamber 10, and the second motion mechanism 22 drives the heating element 30 to move linearly along the axial direction relative to the chamber 10, and the heating element 30 is positioned close to the surface of the aerosol generating matrix 11, thereby achieving spiral heating.

[0083] In other embodiments, the first motion mechanism 21 and the second motion mechanism 22 may also be driven by independent drive mechanisms.

[0084] Please see Figure 8 and Figure 9 In some embodiments, the first motion mechanism 21 includes a base 211 rotatably connected to the cabin 10 and a rotating member 212 fixedly connected to the base 211. The rotating member 212 extends linearly along the axial direction of the cabin 10. The second motion mechanism 22 is movably connected to the rotating member 212 to move along the axial direction of the cabin 10 while the rotating member 212 rotates.

[0085] Thus, by rotating the base 211 to the cabin 10, fixing the rotating part 212 to the base 211, and movably connecting the second motion mechanism 22 to the rotating part 212, the base 211 can drive the rotating part 212 to rotate relative to the cabin 10, and when the rotating part 212 rotates, it drives the second motion mechanism 22 to move linearly along the axial direction relative to the cabin 10. As a result, the aerosol generating matrix 11 rotates with the first motion mechanism 21 relative to the cabin 10, and the heating element 30 moves linearly along the axial direction relative to the cabin 10 with the second motion mechanism 22. The structure is simple and the motion is highly reliable.

[0086] Specifically, the two ends of the chamber 10 along its axial direction can form openings, and the base 211 can be disposed at one end of the two ends of the chamber 10 along its axial direction, covering the opening at that end. The base 211 can be a rotating structure; for example, the base 211 can be disc-shaped, conical, or columnar. The base 211 can support the aerosol generating matrix 11, which is fitted inside the chamber 10. The aerosol generating matrix 11 can be fixedly connected to the radial edge of the base 211 on one axial side and coaxial with the base 211.

[0087] The first motion mechanism 21 rotates around the central axis of the base 211, causing the aerosol generating matrix 11 to rotate around its own central axis. In other words, the aerosol generating matrix 11 rotates under the influence of the base 211.

[0088] The rotating component 212 can be a lead screw 2121, a rope, a conveyor belt, etc.

[0089] Please see Figure 8 and Figure 9 In some embodiments, the second motion mechanism 22 includes a slider 225, which is fixedly connected to the heating element 30 and is sleeved on the rotating element 212 and movably connected to the rotating element 212.

[0090] Thus, by mounting the sliding member 225 on the rotating member 212 and movably connecting it to the sliding member 225, the sliding member 225 can move linearly along the extension direction of the rotating member 212, that is, along the axial direction of the cabin 10. At the same time, the rotating member 212 rotates relative to the sliding member 225, thereby ensuring the stable and reliable linkage between the first motion mechanism 21 and the second motion mechanism 22.

[0091] Specifically, the sliding member 225 can be block-shaped, and a first through hole 2251 is formed on the sliding member 225. The first through hole 2251 passes through the sliding member 225 along the axial direction of the cabin 10, and the rotating member 212 passes through the first through hole 2251. The hole wall of the first through hole 2251 cooperates with the rotating member 212, so that the sliding member 225 and the rotating member 212 form both a rotational connection and a sliding connection. For example, the rotating member 212 is a lead screw 2121, and the surface of the rotating member 212 has alternating threaded grooves and cylindrical surfaces. When the rotating member 212 rotates, it drives the sliding member 225 to make linear reciprocating motion along the axial direction of the rotating member 212 through threaded transmission.

[0092] Optionally, one end of the rotating member 212 is fixed to the rotation center of the base 211, and the base 211 can drive the rotating member 212 and the aerosol generating matrix 11 to rotate. The heating element 30 can be disposed on the side of the sliding member 225 near the aerosol generating matrix 11. The heating element 30 can extend radially from the sliding member 225 toward the aerosol generating matrix 11 and approach the surface of the aerosol generating matrix 11.

[0093] While the aerosol generating matrix 11 rotates with the base 211, the heating element 30 moves linearly along the axial direction with the sliding member 225. Furthermore, the relative radial positions of the rotating member 212, the sliding member 225, and the aerosol generating matrix 11 remain essentially consistent. That is, during the relative motion, the heating element 30 and the aerosol generating matrix 11 maintain a reasonable and essentially consistent thermal radiation distance. This helps improve heating consistency.

[0094] Please see Figure 8 and Figure 9 In some embodiments, the slider 225 is formed with a mounting groove 2253, and the end of the heating element 30 is provided with a mounting seat 31, which is at least partially accommodated in the mounting groove 2253.

[0095] Thus, by having the mounting base 31 at the end of the heating element 30 at least partially accommodated in the mounting groove 2253, the heating element 30 is fixedly connected to the mounting groove 2253, thereby increasing the connection reliability between the heating element 30 and the sliding member 225 and helping to reduce the transfer of heat to the sliding member 225.

[0096] Specifically, the mounting base 31 and the sliding member 225 can be fixedly connected by at least one of the following methods: snap-fit ​​connection, fastener connection, welding, riveting, adhesive connection, etc. The shape and size of the mounting base 31 correspond to and match the shape and size of the mounting groove 2253, and the mounting base 31 can be partially or completely accommodated in the mounting groove 2253.

[0097] For example, the mounting groove 2253 passes through the sliding member 225 axially, the bottom surface 53 of the mounting groove 2253 is radially opposite to the groove opening and the size of the groove opening is smaller than the bottom surface 53, and the cross section of the mounting groove 2253 perpendicular to the axial direction can be "convex" shaped; correspondingly, the end of the mounting seat 31 that is radially away from the heating element 30 abuts against the bottom surface 53 of the groove, and the size of the end of the mounting seat 31 that is radially away from the heating element 30 is larger than the size of the end of the mounting seat 31 that is connected to the heating element 30.

[0098] The heating element 30 is fixedly connected to the mounting base 31, and the end of the heating element 30 connected to the mounting base 31 can also partially extend into the mounting groove 2253. The heating element 30 and the mounting base 31 can be made of materials with different thermal conductivity. The mounting base 31 is made of a material with lower thermal conductivity, which can reduce the transfer of heat to the sliding member 225, thereby reducing heat loss and reducing the impact of the high temperature of the heating element 30 on the sliding member 225.

[0099] Please see Figure 8 and Figure 9In some embodiments, the rotating member 212 is located at the geometric center of the base 211, the base 211 is rotatably arranged around the rotating member 212, and the rotating member 212 and the heating element 30 are respectively located at the two ends of the sliding member 225 along the radial direction of the cabin 10.

[0100] Thus, the sliding member 225 extends radially from the rotating member 212 along the base 211 toward the bulkhead 13, and the heating element 30 is disposed at the end of the sliding member 225 that is radially away from the rotating member 212. This makes the heating element 30 relatively close to the aerosol generating matrix 11 on the bulkhead 13. Furthermore, during the relative movement of the first motion mechanism 21 and the second motion mechanism 22, the distance between the heating element 30 and the aerosol generating matrix 11 on the bulkhead 13 remains relatively stable, which is beneficial to ensuring the consistency of heating.

[0101] Specifically, one axial end of the rotating member 212 is connected to the geometric center of the base 211. The central axis of the base 211 coincides with the central axis of the rotating member 212, and the base 211 and the rotating member 212 rotate around the central axis. A first through hole 2251 and a second through hole 2252, radially spaced, can be formed on the sliding member 225. The first through hole 2251 axially penetrates the sliding member 225 and is directly opposite the geometric center of the base 211. The rotating member 212 passes through the first through hole 2251 and can rotate within it.

[0102] The sliding member 225 has a mounting groove 2253 formed at its radially distal end from the rotating member 212, and the heating element 30 is fixedly mounted in the mounting groove 2253 by a mounting base 31. The heating element 30 can extend radially from the end of the sliding member 225 toward the surface of the aerosol generating matrix 11.

[0103] The second through hole 2252 is disposed between the first through hole 2251 and the mounting groove 2253. The guide member 40 passes through the second through hole 2252, and the sliding member 225 slides along the guide member 40 through the second through hole 2252.

[0104] Please see Figure 8 and Figure 9 In some embodiments, the heating assembly 100 further includes a guide 40, which is parallel to and spaced apart from the rotating member 212. The guide 40 is slidably connected to the sliding member 225 to limit the sliding direction of the sliding member 225.

[0105] Thus, by having the guide member 40 and the rotating member 212 arranged parallel and spaced apart, and the guide member 40 and the sliding member 225 slidably connected, the sliding member 225 is further restricted to move in a straight line along the guide member 40 and the straight line extension direction of the sliding member 225, that is, along the axial direction of the cabin 10, thereby ensuring that the heating element 30 and the aerosol generating device 1000 generate relative movement in a preset manner.

[0106] Specifically, the guide member 40 is parallel to the rotating member 212, that is, the guide member 40 is parallel to the axis of the cabin 10; the sliding member 225 slides along the guide member 40, which is a linear movement along the axis of the cabin 10. The guide member 40 can be a slide rail, guide post 41, rope, conveyor belt, etc.

[0107] Taking the guide post 41 as an example, the guide member 40 can have a second through hole 2252 formed on the sliding member 225, and the second through hole 2252 passes through the sliding member 225 axially. The guide member 40 can be inserted through the second through hole 2252 and fixedly connected to the cabin 10. The guide member 40 can also provide certain structural support for the sliding member 225. The sliding member 225 slides on the mutually parallel guide member 40 and sliding member 225, and the structure is relatively stable and reliable.

[0108] The guide member 40 and the rotating member 212 are arranged radially at intervals along the chamber 10. The guide member 40 may be located between the central axis of the chamber 10 and the aerosol generating matrix 11, and the guide member 40 is fixed relative to the chamber 10. During the rotation of the rotating member 212 and the aerosol generating matrix 11, the radial relative position of the guide member 40, the rotating member 212, and the aerosol generating matrix 11 remains fixed. As explained above, the radial position of the sliding member 225 relative to the aerosol generating matrix 11 remains unchanged during the movement, and the radial relative position of the sliding member 225 and the guide member 40 also remains unchanged, while only the axial positional relationship changes.

[0109] Please see Figures 8-10 In some embodiments, the first motion mechanism 21 further includes a support 213, which is mounted on and fixedly connected to the base 211. The aerosol generating matrix 11 is arranged around the support 213 along the circumference of the cabin 10 and covers at least a portion of the cabin wall 13 of the cabin 10.

[0110] Thus, the aerosol generating matrix 11 is mounted on the base 211 by the bracket 213 and fixedly connected to the base 211. The aerosol generating matrix 11 is arranged around the bracket 213 along the circumference of the cabin 10, so that the aerosol generating matrix 11 is fixedly connected to the base 211. The bracket 213 and the aerosol generating matrix 11 can rotate synchronously with the base 211 relative to the cabin wall 13.

[0111] Specifically, the support 213 can be generally cylindrical, and the aerosol generating matrix 11 can be sleeved on the support 213 and coaxial with the support 213. The aerosol generating matrix 11 can be fixedly connected to the support 213 by fasteners or structural adhesive. The aerosol generating matrix 11 can be located between the support 213 and the bulkhead 13, or it can be located on the side of the support 213 away from the bulkhead 13. For example, the support 213, the aerosol generating matrix 11, and the bulkhead 13 are sleeved sequentially from the inside to the outside, and the rotating component 212, the sliding component 225, and the heating element 30 are disposed inside the support 213. The heating element 30 can partially pass through the support 213 and be opposite to the aerosol generating matrix 11. The support 213, the aerosol generating matrix 11, and the bulkhead 13 can be coaxially arranged.

[0112] Optionally, the support 213 is a hollow cylindrical structure. For example, the support 213 includes a first end ring 2131 and a second end ring 2132 axially opposed to each other, and a connecting portion connecting the first end ring 2131 and the second end ring 2132. The first end ring 2131 is fixedly connected to the base 211, and the aerosol generating matrix 11 can be wound around the connecting portion and the second end ring 2132, or cover the first end ring 2131 and the connecting portion.

[0113] Optionally, the connecting portion is perforated to reduce obstruction between the heating element 30 and the aerosol generating matrix 11. For example, the connecting portion includes at least one connecting strip 2133, with its two ends axially connected to a first end ring 2131 and a second end ring 2132. The number of connecting strips 2133 can also be multiple, with the multiple connecting strips 2133 spaced apart circumferentially along the end rings. The connecting strips 2133 can be narrow strips extending linearly along the axial direction and are sparsely distributed.

[0114] Furthermore, the first end ring 2131 can be fixedly connected to the base 211 via a flange 214. The flange 214 can be stacked on the base 211 and fixedly connected to the base 211. The outer peripheral side of the flange 214 can be approximately gear-shaped, forming protrusions and grooves arranged alternately along the circumference. The end face of the second end ring 2132 facing away from the first end ring 2131 along the axial direction can be formed with concave and convex surfaces that match the flange 214, and engage with the outer peripheral side of the flange 214.

[0115] Please see Figure 6 , Figure 8 and Figure 9 In some embodiments, the cabin 10 includes a top cover 12 and a cabin wall 13. The top cover 12 and the base 211 are opposite each other along the axial direction of the cabin 10. The cabin wall 13 surrounds the top cover 12 and the base 211 along the circumference of the cabin 10. The end of the rotating member 212 away from the base 211 along the axial direction is rotatably connected to the top cover 12.

[0116] Thus, with the top cover 12 and the base 211 facing each other along the axial direction of the cabin 10, and the cabin wall 13 surrounding the top cover 12 and the base 211 along the circumference of the cabin 10, the rotating part 212 is rotatably connected to the top cover 12 at one end along the axial direction away from the base 211. This improves the balance of the rotating part 212 during rotation, thereby improving the structural stability and reliability of the motion mechanism 20, and ensuring that the heating element 30 and the aerosol generating device 1000 generate relative motion in a preset manner.

[0117] Specifically, the top cover 12 and the base 211 respectively cover the openings at both ends of the axial direction of the hull 10. The bulkhead 13 can be directly or indirectly fixedly connected to the top cover 12. The radial edge of the base 211 is movably connected to one axial edge of the bulkhead 13.

[0118] One end of the rotating member 212 is fixedly connected to the base 211, and the other end is rotatably connected to the top cover 12. The geometric centers of the top cover 12 and the base 211 can both be located on the central axis of the rotating member 212 to improve the balance of the first motion mechanism 21 during rotation. The end of the guide member 40 axially away from the base 211 can be fixedly connected to the top cover 12.

[0119] Please see Figure 6 , Figure 8 and Figure 9 In some embodiments, the heating assembly 100 includes an isolation sleeve 50, which is fitted inside the chamber 10. The top cover 12 is closed with the isolation sleeve 50. The isolation sleeve 50 is used to isolate the rotating component 212 and the aerosol generating matrix 11.

[0120] Thus, by fitting the isolation sleeve 50 inside the cabin 10 and covering it with the top cover 12, the isolation sleeve 50 isolates the rotating part 212 and the aerosol generating matrix 11, thereby reducing aerosol contamination of the moving mechanism 20, extending the effective life of the moving mechanism 20, and also playing a certain role in limiting the aerosol generating matrix 11.

[0121] Specifically, the isolation sleeve 50 can be disposed between the support 213 and the bulkhead 13. For example, the isolation sleeve 50, the support 213, the aerosol generating matrix 11, and the bulkhead 10 are sequentially fitted from the inside to the outside and can be coaxially arranged. The rotating component 212 can be located at the central axis of the bulkhead 10. The base 211 can support the isolation sleeve 50 and the support 213, and the base 211 is movably connected to the isolation sleeve 50 so that the base 211 can rotate relative to the isolation sleeve 50.

[0122] Please see Figures 6-8In some embodiments, the isolation sleeve 50 includes a main body 51 and a curved portion 52 connected to the main body 51. The curvature of the main body 51 matches the bulkhead 13 of the cabin 10. The curved portion 52 is recessed from the main body 51 away from the bulkhead 13 of the cabin 10 toward the rotating member 212. The curved portion 52 and the bulkhead 13 of the cabin 10 together define a heating channel 101. The heating element 30 extends at least partially into the heating channel 101.

[0123] Thus, the curved section 52 and the bulkhead 13 together define the heating channel 101, and the heating element 30 extends at least partially into the heating channel 101, so that the aerosol generating matrix 11 is heated in the heating channel 101, thereby facilitating the flow of aerosols along the heating channel 101 for inhalation.

[0124] Specifically, taking the cross-sectional shape of the cabin 10 as an example, the main body 51 is a circle with a diameter slightly smaller than the inner diameter of the cabin 10. The main body 51 surrounds the rotating member 212 and forms two spaced ends in the circumferential direction. The curved part 52 protrudes from the two spaced ends of the main body 51 in the circumferential direction toward the central axis of the isolation sleeve 50. Along the radial direction of the cabin 10, the distance between the curved part 52 and the cabin wall 13 is greater than the distance between the main body 51 and the cabin wall 13. The interval between the curved part 52 and the cabin wall 13 that are radially opposite and spaced apart forms a heating channel 101.

[0125] Optionally, the curved portion 52 is provided with a clearance hole 521, through which the heating element 30 can extend into the heating channel 101. The portion of the heating element 30 extending into the heating channel 101 can move linearly along the axial direction within the heating channel 101. To avoid structural interference, the clearance hole 521 can be elongated and extend axially.

[0126] The connection between the top cover 12 and the curved portion 52 can form a curved edge that matches the curvature of the curved portion 52. The bottom surface 53 of the isolation sleeve 50 can extend radially beyond the range of the curved portion 52 so that the heating channel 101 is open at the top cover 12 and closed on the bottom surface 53.

[0127] Optionally, the aerosol generating matrix 11 is coaxial with the isolation sleeve 50 and rotates. During the rotation of the aerosol generating matrix 11 relative to the isolation sleeve 50, the aerosol generating matrix 11, which is radially opposite to the curved part 52, continuously switches to the fresh part in the circumferential direction. Meanwhile, the heating element 30 moves linearly in the axial direction, continuously changing the position of heating the aerosol generating matrix 11 in the axial direction. Thus, the heating element 30 can continuously heat the fresh aerosol generating matrix 11, resulting in a fast smoke output rate, less scorching, and ensuring that each puff of aerosol inhaled by the user is generated by the fresh aerosol generating matrix 11, thereby improving the user experience.

[0128] Please see Figure 6 and Figure 8In some embodiments, the heating assembly 100 further includes a guide 40 movably connected to the second motion mechanism 22. The guide 40 is parallel to and spaced apart from the rotating member 212. The two ends of the guide 40 are fixedly connected to the top cover 12 and the isolation sleeve 50, respectively.

[0129] Thus, by fixing the two ends of the guide member 40 axially to the top cover 12 and the isolation sleeve 50 respectively, the structural stability of the guide member 40 is improved, thereby ensuring that the sliding member 225 and the heating element 30 move along the direction defined by the guide member 40.

[0130] Specifically, the isolation sleeve 50 includes a bottom surface 53 and a side wall 54. The bottom surface 53 is axially opposite to the top cover 12, and the side wall 54 connects the bottom surface 53 and the top cover 12. The end face of the bottom surface 53 opposite to the top cover 12 is movably connected to the base 211. The two ends of the guide member 40 are fixedly connected to the top cover 12 and the bottom surface 53 respectively. The top cover 12, the guide member 40, and the isolation sleeve 50 remain stationary relative to the cabin 10 when the first motion mechanism 21 and the second motion mechanism 22 move. Correspondingly, the heating channel 101 also remains in a fixed position relative to the cabin 10.

[0131] Please see Figure 6 , Figure 8 and Figure 9 In some embodiments, the aerosol generating matrix 11 includes a matrix layer and a support layer (not shown). The matrix layer and the support layer are stacked along the thickness direction of the aerosol generating matrix 11. The matrix layer is disposed facing the heating element 30 and is used to generate aerosols when heated. The support layer is disposed away from the heating element 30.

[0132] Thus, by stacking the matrix layer and the support layer along the thickness direction of the aerosol generating matrix 11, with the matrix layer facing the heating element 30 and the support layer facing away from the heating element 30, the matrix layer is closer to the heating element 30, which is beneficial for heat absorption and atomization. Furthermore, the support layer can provide structural support for the matrix layer, maintain the stability of the shape, and thus keep the relative motion trajectory between the aerosol generating matrix 11 and the heating element 30 stable.

[0133] Specifically, the stiffness of the support layer is greater than that of the matrix layer. For example, the support layer can be corrugated paper, aluminum foil, etc.

[0134] Optionally, the aerosol generating matrix 11 is thinner to improve heating efficiency and smoke output speed, enabling instant heating and inhalation. For example, the matrix layer of the aerosol generating matrix 11 is 0.3 mm thick and extends continuously in the circumferential direction to form a thin-walled cylindrical structure. The heating element 30 can generate aerosol for inhalation 1 second after heating begins, greatly shortening the user's waiting time.

[0135] Please see Figures 1-3This application provides an aerosol generating device 1000, which includes a housing 200 and a heating component 100 as described in any of the above embodiments, with the chamber 10 fixedly connected to the housing 200.

[0136] The aerosol generating apparatus 1000 of this application, through the spiral trajectory movement of the heating element 30 in the heating assembly 100 relative to the aerosol generating matrix 11, causes the heating element 30 to continuously move to the fresh aerosol generating matrix 11 for heating during the heating process. Furthermore, the aerosol generating matrix 11 has a sheet-like structure, thereby increasing the aerosol escape rate, shortening the heating time, improving the user experience, and increasing the effective suction times of the aerosol generating matrix 11, extending the usage time of a single aerosol generating matrix 11, and thus reducing the replacement frequency of the aerosol generating matrix 11.

[0137] Specifically, the housing 200 can be generally cylindrical, and a heating component 100, a battery 500, a control component 600, etc. can be installed inside it. The cross-sectional shape of the outer contour of the housing 200 includes, but is not limited to, a circle, an ellipse, a racetrack shape, a rectangle, a triangle, a regular polygon, a non-regular polygon, a combination of shapes, or other irregular shapes.

[0138] The heating component 100 is the heat source in the aerosol generating device 1000. The heating component 100 generates heat to heat the aerosol generating matrix 11 and cause the aerosol generating matrix 11 to generate aerosols. The chamber 10 can be fitted inside the shell 200. The chamber wall 13 and the top cover 12 can be fixedly connected to the shell 200, respectively. The shell 200 fixedly connected to the chamber wall 13 and the top cover 12 can be different components and structures. The outer contour cross-sectional shape of the chamber wall 13 matches the inner contour cross-sectional shape of the shell 200. For example, both the chamber wall 13 and the shell 200 have annular cross-sectional shapes.

[0139] Please see Figure 3 and Figure 4 In some embodiments, the aerosol generating device 1000 includes a drive 300 connected to a motion mechanism 20, the drive 300 being used to drive the motion mechanism 20 to move relative to the housing 200.

[0140] Thus, the drive member 300 is connected to the motion mechanism 20 and drives the motion mechanism 20 to move relative to the housing 200, thereby providing driving force for the relative motion of the aerosol generating matrix 11 and the heating element 30, and making it easy to control the relative motion state of the aerosol generating matrix 11 and the heating element 30 through the drive member 300.

[0141] Specifically, the drive unit 300 can be a motor, which is electrically connected to the battery 500 and can convert electrical energy into kinetic energy to drive the motion mechanism 20 to rotate. With the axis of the cabin 10 as the vertical direction, the drive unit 300 can be located below the heating assembly 100.

[0142] The first motion mechanism 21 is directly connected to the drive member 300. For example, the rotating member 212 is a lead screw 2121. The rotating member 212 passes through the geometric center of the base 211 and is connected to the output shaft of the drive member 300. The rotating member 212 can be connected to the output shaft of the motor along the axial direction so that the drive member 300 drives the base 211 and the rotating member 212 to rotate around the axial direction of the output shaft when running.

[0143] The second motion mechanism 22 is movably connected to the first motion mechanism 21 and moves linearly along the axial direction under the drive of the first motion mechanism 21.

[0144] The aerosol generating matrix 11 is generally cylindrical and coaxial with the base 211. The aerosol generating matrix 11 can be fixedly mounted on the base 211 via the bracket 213, and rotates relative to the housing 200 around the rotating component 212 under the drive of the base 211. The heating element 30 is fixedly connected to the second motion mechanism 22. The heating element 30 moves linearly along the axial direction relative to the housing 200, thereby causing the driving component 30 to move relative to the aerosol generating matrix 11 when it runs. The linear motion of the heating element 30 is coupled with the rotational motion of the aerosol generating matrix 11, which is equivalent to the heating element 30 moving along a spiral trajectory on the surface of the aerosol generating matrix 11.

[0145] Combination Figure 3 The heating element 30 can be electrically connected to the battery 500 and the control component 600. The heating element 30 can convert the electrical energy provided by the battery 500 into heat energy. The control component 600 can control the output of the battery 500 and the heating state of the heating element 30. The heating state of the heating element 30 can be synchronized with the operating state of the drive component 300. While generating heat to heat the aerosol generating matrix 11, the heating element 30 can move relative to the aerosol generating matrix 11 to achieve spiral heating.

[0146] Furthermore, the control component 600 can control the operating state of the drive unit 300 and the heating state of the heating element 30 according to the user's suction state. For example, when the user is performing suction, the control component 300 is operated to drive the heating element 30 and the aerosol generating matrix 11 to move relative to each other, while the heating element 30 is controlled to generate heat to heat a section of fresh aerosol generating matrix 11. During the intervals between user suction, the control component 600 is controlled to stop heating and the control component 300 is controlled to stop operating.

[0147] Please see Figure 4 , Figure 4The dashed arrows are used to indicate the direction of airflow. In some embodiments, the aerosol generating device 1000 includes a nozzle 400 connected to the housing 200, a suction channel 401 formed in the nozzle 400, and a heating assembly 100 forming a heating channel 101 communicating with the suction channel 401. The aerosol generating matrix 11 and the heating element 30 are both at least partially housed in the heating channel 101.

[0148] Thus, a suction channel 401 is formed within the nozzle 400, which is connected to the heating channel 101. The aerosol generating matrix 11 and the heating element 30 are both at least partially contained in the heating channel 101. As a result, after the aerosol is generated in the heating channel 101, it can enter the suction channel 401 with the airflow and be inhaled. The flow path of the aerosol is relatively simple, the structure is stable, and it is convenient for users to inhale.

[0149] Specifically, the nozzle 400 is hollow inside, and the inner wall of the nozzle 400 defines a suction passage 401. The housing 200 has an opening at one end along the axial direction, and the nozzle 400 can be closed at the end of the housing 200 where the opening is formed; the heating assembly 100 can be disposed at the opening of the housing 200.

[0150] Optionally, combined Figure 8 The chamber 10 may also include an end cap 60 that covers the chamber wall 13, and the end cap 60 is disposed on the side of the top cover 12 opposite to the base 211. The end cap 60 and the portion of the chamber wall 13 connected to the end cap 60 can extend into the suction nozzle 400, and the surface of the end cap 60 opposite to the base 211 and the inner wall surface of the suction nozzle 400 together define a suction passage 401. The end cap 60 may be formed with a vent hole 601, which may be axially opposite to the curved portion 52 so that the vent hole 601 connects the heating channel 101 and the suction passage 401.

[0151] Optionally, the shape and size of the inner and outer contours of the cross-section of the nozzle 400 at different axial positions can be varied to adapt to different structural and usage requirements. The outer contour shape of the cross-section of the nozzle 400 near the heating assembly 100 along the axial direction matches the outer contour shape of the cross-section of the housing 200. For example, the outer contour of the cross-section of the housing 200 is circular, and the end of the nozzle 400 that covers the housing 200 can be a hollow cylindrical structure. The end of the nozzle 400 away from the heating assembly 100 can be formed into a flat cylindrical structure for the user to suck on.

[0152] Please see Figure 4 In some embodiments, the housing 200 forms an air intake channel 201, which connects the heating channel 101 and the external environment of the housing 200.

[0153] Thus, an air intake channel 201 is formed through the housing 200, which connects the heating channel 101 with the external environment of the housing 200, allowing external air to enter the heating channel 101 through the air intake channel 201, thereby forming an airflow along the air intake channel 201-heating channel 101-suction airway 401, which is beneficial for driving aerosols to escape from the heating channel 101 and enter the user's respiratory system.

[0154] Specifically, the housing 200 can form an air intake channel 201 through holes, pipes, cavities, etc., formed by one or more components. The air intake channel 201 can form a single airflow path. For example, the air intake channel 201 has only two openings, one of which communicates with the external environment of the housing 200, and the other opening communicates with the heating channel 101 of the heating assembly 100. Air can enter the air intake channel 201 from outside the housing 200, and then enter the heating channel 101 along the air intake channel 201. In the heating channel 101, it mixes with aerosol to form an airflow carrying aerosol, which continues to flow into the suction channel along the heating channel 101, and finally flows out from the end of the suction channel in the nozzle 400.

[0155] Please see Figure 4 and Figure 5 In some embodiments, the housing 200 includes a first housing 210 and a second housing 220 fixedly connected to the first housing 210. The first housing 210 surrounds the second housing 220 and is used to isolate the internal and external environments of the housing 200. The second housing 220 covers the heating assembly 100.

[0156] A first air inlet 2101 is formed on the first shell 210, and a second air inlet 2201 is formed by the second shell 220 and the bulkhead 13 of the cabin 10. The first air inlet 2101 connects the external environment of the first shell 210 with the second air inlet 2201. The second air inlet 2201 is connected to the heating channel 101. The first air inlet 2101 and the second air inlet 2201 respectively form a portion of the air intake channel 201.

[0157] Thus, the first shell 210 isolates the internal and external environments of the housing 200, and the second shell 220 covers the heating assembly 100, protecting and supporting the heating assembly 100 and other components inside the housing 200; the first air inlet 2101 and the second air inlet sequentially connect the external environment of the housing 200 and the heating channel 101, thereby introducing fresh external air into the heating channel 101, which helps the aerosol enter the suction channel 401 with the airflow, and also facilitates uniform heating.

[0158] Specifically, the first shell 210 can be a cylindrical structure coaxial with the cabin 10, and the axial length of the first shell 210 is significantly greater than the length of the cabin 10. Both the first shell 210 and the second shell 220 are connected to the suction nozzle 400, which can be connected to the axial ends of the first shell 210 and the second shell 220. Figure 3 With the axial direction of the cabin 10 as the vertical direction, the suction nozzle 400 is located above the heating assembly 100, while components such as the drive unit 300, battery 500, and control unit 600 can be arranged below the heating assembly 100. The second shell 220 includes an upper shell 2202 surrounding the heating assembly 100 and a lower shell 2203 surrounding the drive unit 300 and battery 500. The upper shell 2202 can be a cylindrical structure, and its diameter is between the outer diameter of the cabin 10 and the inner diameter of the first shell 210 surrounding the cabin 10.

[0159] In this embodiment, the first air inlet 2101 is located on the wall surface opposite to the lower shell 2203 of the first shell 210, and the second air inlet 2201 is located on the end face of the upper shell 2202 away from the nozzle 400. The second air inlet 2201 can extend axially from the end face of the upper shell 2202 through the bulkhead 13, or be opposite to the section between the bulkhead 13 and the aerosol generating matrix 11, so that the second air inlet 2201 communicates with the heating channel 101. The wall surface of the first shell 210 forming the first air inlet 2101 is opposite to and spaced from the lower shell 2203, and together they form a portion of the air intake channel 201. The second air inlet 2201 is located within the section between the wall surface of the first shell 210 forming the first air inlet 2101 and the lower shell 2203, so that the first air inlet 2101 and the second air inlet 2201 communicate.

[0160] When the user performs the suction action, external air enters the housing 200 through the first air inlet 2101, then enters the heating channel 101 through the second air inlet 2201, mixes with the aerosol in the heating channel 101, and then carries the aerosol into the suction airway 401, and finally enters the user's respiratory system along the suction airway 401.
