Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically, to an aerosol generation apparatus and an aerosol generation system. 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 ​​added to the aerosol generating device as a consumable for single use; however, the effective number of suction ports of the aerosol generating matrix is ​​insufficient to meet the needs of continuous suction with a large number of ports. Utility Model Content

[0003] This application provides an aerosol generating apparatus and an aerosol generating system.

[0004] The aerosol generating apparatus of this application embodiment is used to accommodate aerosol generating consumables. The aerosol generating consumables include a support and an aerosol generating product. The support is provided with a plurality of receiving holes, and the aerosol generating product is accommodated in the receiving holes.

[0005] The aerosol generating device includes:

[0006] A pushing mechanism is used to push the aerosol-generated product from the support out of the support, and to recycle the aerosol-generated product from outside the support back into the support; and

[0007] The heating mechanism has a heating chamber to heat the aerosol generated from the support.

[0008] The aerosol generating device of this application uses a pushing mechanism to push the aerosol generating product in the support outwards, a heating mechanism to heat the aerosol generating product removed from the support, and the pushing mechanism to push the aerosol generating product back into the support. Thus, the heating mechanism can sequentially heat the aerosol generating products removed from different receiving holes, increasing the number of continuous suction ports, while also reducing the replacement frequency of aerosol generating consumables. Moreover, the process of replacing aerosol generating products can be seamless for the user, and the size of the aerosol generating device can be greatly reduced.

[0009] In some embodiments, the heating mechanism includes a housing and a heating element, the housing having a heating cavity for accommodating an aerosol-generated article removed from a support, and the heating element being disposed on the housing.

[0010] In this way, the aerosol-generated article is contained within the housing, and the heating element is positioned on the side of the housing away from the heating chamber. This allows the housing to form an independent heating chamber and isolate the heating element from the aerosol, reducing the risk of cross-contamination. Alternatively, the heating element can be positioned on the inner wall of the housing, which facilitates rapid heating and saves energy.

[0011] In some embodiments, the heating mechanism includes a conductive element and a temperature sensing element. The conductive element is electrically connected to the heating element, and the temperature sensing element is in contact with the conductive element or the housing. The temperature sensing element and the heating element are spaced apart, and the minimum distance between the temperature sensing element and the heating element is less than or equal to 3 mm. The temperature sensing element is used to detect the temperature of the heating mechanism.

[0012] In this way, by having the temperature sensing element in contact with the conductive or housing component, and the temperature sensing element and the heating element spaced apart, with the minimum distance between the temperature sensing element and the heating element being less than or equal to 3mm, the temperature sensing element can quickly and accurately reflect the temperature of the heating mechanism without being damaged due to excessively high temperature, or avoiding feedback lag caused by excessively rapid heating, and at a lower cost.

[0013] In some embodiments, the heating mechanism includes a fixing component fixedly connected to a receiving member, and a conductive member fixedly disposed relative to a heating element via the fixing component; and / or, the heating element is positioned relative to the receiving member via the fixing component.

[0014] This simplifies the positioning structure of the heating element, makes it easier to position the heating element in the appropriate position on the housing, and makes the heating element less prone to deformation, which helps to improve the consistency of the heating mechanism.

[0015] In some implementations, the temperature sensing element is a thermocouple, and the temperature sensing element is welded or thermally fused to a conductive component.

[0016] In this way, the temperature sensing element and the conductive component form a solder joint or melting point. The position of the temperature sensing element relative to the conductive component and the heating element is not affected by the assembly relationship or is minimally affected by the assembly relationship, thereby reducing the possibility of unstable temperature sensing position caused by assembly errors and improving temperature measurement accuracy.

[0017] In some implementations, the minimum distance D1 between the connection point of the temperature sensing element and the conductive element and the heating element satisfies: 0.5mm≤D1≤3mm.

[0018] In this way, by setting the connection position of the temperature sensing element and the conductive part and the minimum distance D1 between them and the heating element within a reasonable range, the relative positions of the temperature sensing element and the heating element are closer, resulting in higher timeliness and accuracy of temperature measurement. This avoids feedback lag caused by excessively rapid heating, and also makes the temperature sensing element less prone to high-temperature damage. Furthermore, it can reduce the temperature resistance standard of the temperature sensing element and lower costs.

[0019] In some embodiments, the housing is a metal tube that forms a heating cavity. One end of the temperature sensing element is welded to the outer wall of the metal tube, and the temperature sensing element is positioned away from the heating element. The minimum distance D2 between the connection position of the temperature sensing element and the metal tube and the heating element satisfies: 1mm≤D2≤3mm.

[0020] In this way, by welding the temperature sensing end of the temperature sensing element to the outer wall of the metal tube, the metal tube forms a heating chamber, and the temperature sensing element is set away from the heating element, the position of the temperature sensing element relative to the heating element is fixed and the distance is close. This can ensure accurate and timely temperature measurement, avoid problems such as high temperature damage to the temperature sensing element, and also reduce the temperature resistance standard of the temperature sensing element, thus reducing costs.

[0021] In some embodiments, the fixing component includes a retaining member, and the temperature sensing element includes a temperature sensing end, two connecting parts and a receiving part connected in sequence. The temperature sensing end is close to the heating element, and the two connecting parts are spaced apart in the retaining member.

[0022] In this way, by bringing the temperature measuring end close to the heating element, the two connecting parts are connected to the temperature measuring end and spaced apart in the retaining part, and the receiving part is connected to the two connecting parts, so that the position of the temperature measuring end relative to the fixed component and the heating element is fixed, which is beneficial to temperature measurement stability.

[0023] In some embodiments, the retaining member is provided with two slots at intervals, and two connecting parts are respectively inserted into the two slots. The retaining member includes a partition and a limiting part connected to the partition. The partition is located between the two slots, and the limiting part abuts against the temperature measuring end to limit the position of the temperature measuring end.

[0024] Thus, by having the partition located between the two slots, and the limiting part connected to the partition and abutting against the temperature measuring end, the position of the temperature measuring end and the connecting part is restricted, ensuring that the position of the temperature measuring end relative to the fixed component and the heating element is fixed, thereby improving the temperature measurement stability.

[0025] In some embodiments, the housing is tubular, and the heating mechanism includes end caps and supports. The heating element and the supports are sequentially sleeved on the outside of the housing, and the end caps are sleeved on both ends of the housing along the axial direction and fixedly connected to the supports.

[0026] In this way, the heating element and the support are sequentially fitted onto the outer side of the housing, and the end caps are fitted onto both ends of the housing along the axial direction and fixedly connected to the support, which facilitates the assembly of the heating mechanism as a whole and can provide a certain degree of protection and positioning for the housing and the heating element.

[0027] In some embodiments, the heating mechanism includes a conductive element electrically connected to the heating element, and the end cap is provided with a wire outlet groove, through which the conductive element passes and is fixedly connected to the heating element.

[0028] Thus, by fitting end caps onto both ends of the receiving component along the axial direction, and by providing wire outlet grooves on the end caps, the conductive component passes through the wire outlet grooves and is fixedly connected to the heating element, thereby restricting the axial position of the conductive component relative to the heating element.

[0029] In some embodiments, the two ends of the heating element along the axial direction of the receiver are a first connecting end and a second connecting end, respectively, and the heating element extends spirally between the first connecting end and the second connecting end;

[0030] The conductive component includes a first conductive end connected to a first connection end and a second conductive end connected to a second connection end. The first and second conductive ends extend along the extension line of the extension path of the heating element on the outer surface of the housing, and each of the first and second conductive ends passes through a wire outlet groove.

[0031] Thus, the heating element extends spirally between the first and second connecting ends, and the first and second conductive ends are wrapped around the surface of the housing for a period before being led outwards. This avoids high-temperature damage to the fixing components, reduces the temperature resistance requirements of the fixing components, and lowers costs. Furthermore, since the first and second conductive ends are axially positioned through the wire outlet groove, the positions of the first and second connecting ends can be limited by restricting their axial positions. The fit between the heating element and the housing can be adjusted by tightening or loosening the conductive parts, ensuring the heating element adheres tightly to the outer surface of the housing, thereby improving the effective utilization of heat. Additionally, the spiral extension of the first and second conductive ends along the extension path of the heating element on the outer surface of the housing reduces the temperature of the conductive parts as they pass through the insulation, further minimizing the impact on other components.

[0032] In some embodiments, the end cap includes a first end cap and a second end cap, which are respectively sleeved on both ends of the axial direction of the receiving member. Both the first end cap and the second end cap are provided with hook-shaped portions, which protrude from the opposite end faces of the first end cap and the second end cap, and a wire outlet groove is formed on the hook-shaped portions.

[0033] Thus, the first conductive end and the second conductive end pass through the two wire outlet grooves respectively and are connected to the two ends of the heating element in the axial direction respectively. The hook-shaped part protrudes from the end faces of the first end cover and the second end cover opposite to each other, thereby restricting the axial position of the first conductive end, the first connecting end, the second conductive end and the second conductive end.

[0034] In some embodiments, the hook-shaped portion and the end face of the end cap to which it is connected together form a wire outlet groove, and the opening of the wire outlet groove is formed on the surface of the hook-shaped portion along the circumferential side of the end cap.

[0035] In this way, the first conductive end and the second conductive end are axially limited in the outlet groove, and the first conductive end or the second conductive end is further prevented from slipping out of the outlet groove.

[0036] In some embodiments, at least one end cap is provided with a first heat insulation portion, the first heat insulation portion including a plurality of spaced first protrusions, the first protrusions protruding from the surface of the end cap toward the receiving member and abutting against the outer peripheral surface of the receiving member.

[0037] Thus, by having the first protrusion protrude from the surface of the end cap facing the receiving element and abut against the outer peripheral surface of the receiving element, the contact area between the end cap and the receiving element is reduced, and the heat capacity of the end cap itself is reduced, thereby reducing the heat absorption of the end cap and improving the heating efficiency and heating speed inside the heating mechanism.

[0038] In some embodiments, at least one end cap is provided with a second heat insulation portion, the second heat insulation portion including a plurality of spaced second protrusions, the second protrusions protruding from the surface of the end cap toward the support and abutting against the inner circumferential surface of the support.

[0039] Thus, by having the second protrusion protrude from the surface of the end cap facing the support and abut against the inner circumferential surface of the support, the contact area between the end cap and the support is reduced, and the heat capacity of the end cap itself is also reduced, thereby reducing the heat transfer from the end cap to the outside and improving the heating efficiency and heating speed inside the heating mechanism.

[0040] In some embodiments, the heating mechanism includes a conductive element and a heat insulation element, the conductive element being electrically connected to the heating element, and the portion of the conductive element near the heating element passing through the heat insulation element.

[0041] In this way, by having the conductive part close to the heating element pass through the heat insulation component, the exposed conductive part is prevented from getting too hot and melting other parts it comes into contact with, thereby reducing the risk of structural failure or odor.

[0042] In some embodiments, the heating mechanism includes a support member, a heating element and the support member being sequentially sleeved outside the receiving member, the support member having a mounting groove, and a heat insulation member being disposed in the mounting groove.

[0043] This strengthens the connection between the insulation component and the support component, and the insulation component isolates the contact between the conductive component and the support component, thus providing thermal insulation protection for the support component.

[0044] In some embodiments, the receiving member, end cap, and support member all have through holes on the side facing the bracket. One of the multiple receiving holes is opposite to and communicates with the heating chamber along the axial direction of the receiving member. The edge of the through hole of at least one of the receiving member, end cap, and support member is provided with a guide structure, which includes an inclined surface forming an angle with the depth direction of the receiving hole.

[0045] Thus, by providing a guide structure at least one of the three components—the receiving part, the end cap, and the support—towards the edge of the through hole of the receiving hole, the guide structure includes an inclined surface forming an angle with the depth direction of the receiving part. This can prevent the step surface from blocking the movement of the aerosol-generated product due to manufacturing errors, thus avoiding problems such as jamming. It also helps the aerosol-generated product to be smoothly pushed into the heating chamber from the receiving hole or returned to the receiving hole from the heating chamber.

[0046] In some embodiments, the angle formed by the inclined plane and the depth direction of the receiving hole is greater than 0° and less than 45°.

[0047] In this way, by setting the angle between the inclined plane and the depth direction of the receiving hole within a reasonable range, the movement of the aerosol-generated product is ensured to proceed smoothly.

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application.

In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0074] In related technologies, aerosol generating devices extract heated aerosol products through openings in the outer casing and replace them with fresh aerosol products via a moving mechanism inside the casing. This replacement method still requires manual operation by the user, which is rather cumbersome. To achieve automatic replacement of aerosol products, a waste bin can be installed inside the aerosol generating device. An internal moving mechanism transfers the heated aerosol products to the waste bin. While this method eliminates the need for user operation, the waste bin occupies a large internal space with low space utilization, necessitating a corresponding increase in the size of the aerosol generating device. It also requires additional cleaning, limiting the improvement in ease of use.

[0075] Please see Figures 1-3 This application provides an aerosol generation system 100, which may include an aerosol generation device 10, an aerosol generation consumable 20, and an aerosol generation article 22.

[0076] The aerosol generating device 10 is a structure capable of generating aerosols by applying resistance heating, electromagnetic heating, infrared heating, microwave heating, or other methods to the aerosol generating matrix 221. An aerosol generating consumable 20 is replaceably mounted on the aerosol generating device 10, allowing the device to heat the aerosol generating matrix 221 within the consumable 20 to generate aerosols.

[0077] Please see Figure 4 and Figure 5 In some embodiments of this application, the aerosol generating device 10 includes a heating mechanism 13, which is provided with a heating chamber 131 for providing a place for heating and atomizing the aerosol generating matrix 221.

[0078] In some embodiments of this application, the aerosol generating apparatus 10 includes a rotation drive mechanism 15, which is used to drive the aerosol generating consumable 20 and / or the aerosol generating product 22 to rotate, thereby realizing the rotation of the position of the aerosol generating product 22.

[0079] In some embodiments of this application, the aerosol generating apparatus 10 includes a pushing mechanism 12, which is used to push the aerosol generating product 22 rotated to a fixed position into the heating chamber 131, and to push the heated aerosol generating product 22 out of the heating chamber 131 and back to its original position.

[0080] The working principle of the aerosol generation system 100 is as follows: the aerosol generation consumable 20 carries multiple aerosol generation products 22 and is aligned and assembled with the rotation drive mechanism 15, and is installed in the aerosol generation device 10, so that the position of one of the aerosol generation products 22 corresponds to the pusher mechanism 12 and the heating mechanism 13; the pusher mechanism 12 pushes the aerosol generation product 22 at the corresponding position into the heating chamber 131, and the heating mechanism 13 heats the aerosol generation product 22; after heating is completed, the pusher mechanism 12 pushes the aerosol generation product 22 in the heating chamber 131 back to its original position in the aerosol generation consumable; then, the rotation drive mechanism 15 drives the aerosol generation consumable 20 to rotate, changing the position of the aerosol generation product 22, so that another unheated aerosol generation product 22 corresponds to the position of the pusher mechanism 12 and the heating mechanism 13; the pusher mechanism 12 pushes another unheated aerosol generation product 22 into the heating chamber 131 for heating. Repeat the above steps of pushing, heating, and rotating until all aerosol products 22 on the aerosol generating consumable 20 have been heated. By coordinating the rotation drive mechanism 15, the pushing mechanism 12, and the heating mechanism 13, multiple aerosol generating products 22 can be heated alternately, thereby increasing the number of suction ports and improving the user experience.

[0081] After the aerosol generation products 22 on the aerosol generation consumable 20 have been heated and have exited the heating chamber 131 and returned to their original positions, the user can remove the consumed aerosol generation consumable 20 from the aerosol generation device 10 and replace it with a new aerosol generation consumable 20.

[0082] Thus, the aerosol generating device 10 can automatically rotate the heating of the aerosol generating product 22 inside the device, eliminating the need for manual operation by the user, improving ease of use, saving space, and facilitating product miniaturization. Furthermore, the outer surface of the aerosol generating device 10 does not require a separate opening for the removal of the aerosol generating product 22, improving the sealing of the suction process. In addition, the aerosol generating product 22 on the aerosol generating consumable 20 can be individually replaced after removal, resulting in a large number of reusable parts and improving environmental friendliness.

[0083] The specific composition of the aerosol generating matrix 221 is not limited herein. Exemplarily, in some embodiments, the aerosol generating matrix 221 may include plant components, auxiliary components, smoke-generating agent components, binder components, etc. The aerosol generating matrix 221 may be in a fully solid or semi-solid state. The aerosol generating matrix 221 may be prepared using processes such as rolling, slurry preparation, die casting, and extrusion.

[0084] Aerosol generating matrix 221 is heated and atomized 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.

[0085] When the aerosol generating matrix 221 is in a completely solid state, the aerosol generating matrix 221 can be in various shapes such as sheet, block, rod, and tube.

[0086] Please see Figures 2-4 The aerosol generating apparatus 10 of this application embodiment is used to accommodate aerosol generating consumable 20. The aerosol generating consumable 20 includes a support 21 and an aerosol generating product 22. The support 21 is provided with a plurality of receiving holes 211, and the aerosol generating product 22 is accommodated in the receiving holes 211.

[0087] The aerosol generating device 10 includes a pushing mechanism and a heating mechanism 13. The pushing mechanism is used to push the aerosol generating product 22 in the support 21 out of the support 21 and to recycle the aerosol generating product 22 outside the support 21 back into the support 21. The heating mechanism 13 is provided with a heating chamber 131 to heat the aerosol generating product 22 removed from the support 21. Moreover, the process of replacing the aerosol generating product can be seamless for the user and can greatly reduce the size of the aerosol generating device.

[0088] The aerosol generating apparatus 10 of this application pushes the aerosol generating product 22 in the support 21 out of the support 21 through the pushing mechanism. The heating mechanism 13 heats the aerosol generating product 22 that has been removed from the support 21. The pushing mechanism then pushes the aerosol generating product 22 back into the support 21. Thus, the heating mechanism 13 can sequentially heat the aerosol generating products 22 that have been removed from different receiving holes 211, increasing the number of continuous suction ports and reducing the replacement frequency of the aerosol generating consumable 20.

[0089] Specifically, the support 21 loads the aerosol generating article 22 through the receiving hole 211, stabilizing the position of the aerosol generating article 22 and thus stabilizing the amount of aerosol generated. This application does not limit the shape of the support 21; for example, the support 21 can be approximately cylindrical, block-shaped, or other structural shapes.

[0090] For example, the support 21 is approximately cylindrical, and the shape of the receiving hole 211 can match the shape of the aerosol generating article 22. For instance, the aerosol generating article 22 is cylindrical, and the receiving hole 211 is a circular hole. At least one aerosol generating article 22 can be accommodated in each receiving hole 211.

[0091] Optionally, each receiving hole 211 may contain at least one aerosol generating article 22. For example, each receiving hole 211 may contain one aerosol generating article.

[0092] Optionally, the upper part of the bracket 21 has a receiving hole 211 that accommodates the aerosol generating product 22, while the other part of the receiving hole 211 may be empty or may accommodate a counterweight or other components.

[0093] The heating mechanism 13 can form a circumferential temperature field in the heating chamber 131 to achieve central heating of the aerosol-generating article 22 in the heating chamber 131. For example, the heating mechanism 13 may include a needle-shaped heating element 133 extending into the center of the heating chamber 131. When the aerosol-generating article 22 is pushed into the heating chamber 131, the heating element 133 is also inserted into the aerosol-generating article 22, so that the heating element 133 radiates heat from the inside to the outside, heating the aerosol-generating article 22.

[0094] Please see Figure 5 In some embodiments, the heating mechanism 13 includes a receiving member 132 and a heating element 133, the receiving member 132 forming a heating cavity 131, and the heating element 133 disposed on the receiving member 132.

[0095] Thus, by forming a heating chamber 131 through the receiving member 132 and containing the aerosol generating article 22, it is beneficial to maintain the stability of the aerosol generating article 22 during the heating process.

[0096] Specifically, the heating element 133 can be a resistance wire or heating grid heated by resistance, or a solenoid heated by induction, or a heating element heated by infrared or microwave. The housing 132 can be a hollow structure, and the hollow section of the housing 132 forms a heating cavity 131. The housing 132 can be made of materials such as metal, ceramic, or high-temperature resistant glass.

[0097] Furthermore, the heating element 133 is positioned away from the heating chamber 131. This helps to keep the heating element 133 clean and reduces the risk of aerosol or condensate contamination of other components.

[0098] In some embodiments, the housing 132 is cylindrical and surrounds a heating cavity 131, and the heating element 133 is also cylindrical or solenoid-shaped, and the heating element 133 can be sleeved on the outside of the housing 132. In this embodiment, the heating element 133 radiates heat from the periphery of the aerosol generating article 22 inward.

[0099] In other embodiments, the heating element 133 may also be disposed on the inner wall of the receiving member 132, which is beneficial for rapid heating and energy saving.

[0100] The feeding mechanism 12 can push the aerosol generating article 22 along its length direction, moving it between the receiving hole 211 and the heating chamber 131. The depth direction of the heating chamber 131 can be parallel to the depth direction of the receiving hole 211 and the length direction of the aerosol generating article 22. The depth direction of the receiving hole 211 is defined as the vertical direction, and the heating chamber 131 and the aerosol generating article 22 containing the article to be heated are vertically aligned.

[0101] In some embodiments, the length of the heating chamber 131 is close to the length of the aerosol-generated article 22, and the pushing mechanism 12 can push the entire aerosol-generated article 22 into the heating chamber 131 for heating.

[0102] In other embodiments, the length of the heating chamber 131 is close to or greater than the length of the aerosol generating article 22, and the pushing mechanism 12 can push the aerosol generating article 22 segment by segment for heating. During the heating process, the aerosol generating article 22 may be partially contained in the heating chamber 131 and the other part may be located outside the heating chamber 131.

[0103] The aerosol generating article 22 can be heated in two, three, four, or more segments. Different segments of the aerosol generating article 22 may not overlap; there may also be overlapping portions between the upper and lower segments of the aerosol generating article 22. The aerosol generating article 22 can be heated sequentially from top to bottom or from bottom to top along its own length, or different areas of the aerosol generating article 22 may be heated in other sequences.

[0104] Please see Figure 3 and Figure 4In some embodiments, the feeding mechanism 12 includes a feeding drive 121 and a pushing member 122. The feeding drive 121 is used to drive the pushing member 122 to move along the depth direction of the receiving hole 211, so that the pushing member 122 pushes the aerosol generating article 22 in the receiving hole 211 out of the receiving hole 211, or pushes the aerosol generating article 22 located outside the receiving hole 211 back into the receiving hole 211.

[0105] Thus, by driving the pusher 122 along the depth direction of the receiving hole 211 through the pusher 121, the pusher 122 can push the aerosol generating product 22 in the receiving hole 211 out of the receiving hole 211, or push the aerosol generating product 22 located outside the receiving hole 211 back into the receiving hole 211, thereby realizing the switching of the aerosol generating product 22, improving convenience, and helping to continuously generate aerosol in the aerosol generating device 10, realizing large-scale suction.

[0106] Specifically, the pusher drive 121 can be moved by driving the pusher 122 through one of the following driving methods: electric drive, hydraulic drive, air pump, etc. The pusher 122 can push the aerosol generating product 22 to move through rigid components such as push rod 1223 and push block, or it can pull the aerosol generating product 22 through ropes, chains, conveyor belts, etc. A part of the pusher 122 can extend into the receiving hole 211 or notch 217 and connect with the aerosol generating product 22.

[0107] The direction along the depth of the receiving hole 211 from the first end face 214 to the second end face 215 of the bracket 21 is defined as the top-to-bottom direction. The principle of the feeding mechanism 12 in conjunction with the aerosol-generating consumable 20 can be as follows:

[0108] During initial use, the pusher 121 drives the pusher 122 upward, pushing an aerosol-generating product 22 out of its receiving hole 211 and into the heating chamber 131 for the user to inhale. After the aerosol-generating product 22 is heated, the pusher 122 pushes it back into its original receiving hole 211. Then, the support 21 and the aerosol-generating products 22 on it can move (e.g., rotate) relative to the pusher 122, so that the unheated aerosol-generating products 22 correspond to the pusher 122. The pusher 122 then pushes the unheated aerosol-generating products 22 into the heating chamber 131 again. This process is repeated until all the aerosol-generating products 22 on the support 21 are heated, and the aerosol-generating consumable 20 is consumed.

[0109] Please see Figure 3 and Figure 4In some embodiments, the pusher 122 includes a first pusher 1221, a second pusher 1222, and a push rod 1223. The first pusher 1221 and the second pusher 1222 are spaced apart along the depth direction of the receiving hole 211 and are configured to be located on both sides of the bracket 21, respectively. The push rod 1223 connects the first pusher 1221 and the second pusher 1222. The first pusher 1221 is connected to the pusher drive 121. Under the drive of the pusher drive 121, the first pusher 1221 pushes the aerosol generating article 22 in the bracket 21 out of the bracket 21, and the second pusher 1222 pushes the aerosol generating article 22 located outside the bracket 21 back into the bracket 21.

[0110] Thus, with the first pushing part 1221 and the second pushing part 1222 located on both sides of the bracket 21 along the depth square of the receiving hole 211, the first pushing part 1221 and the second pushing part 1222 can push the aerosol generating product 22 from one side to the other side in the depth direction of the receiving hole 211, and make the movement posture of the aerosol generating product 22 exiting and entering the receiving hole 211 more stable.

[0111] Specifically, the first pushing part 1221, the push rod 1223, and the second pushing part 1222 can be arranged sequentially along the depth direction of the receiving hole 211. The first pushing part 1221 and the second pushing part 1222 can be directly opposite each other along the axial direction of the receiving hole 211, and the push rod 1223 can be offset relative to the first pushing part 1221 and the second pushing part 1222 in the axial direction of the receiving hole 211. The first pushing part 1221 and the second pushing part 1222 can be approximately cylindrical or cylindrical in shape. The push rod 1223 can include a long rod, plate, or thin sheet, etc., to reduce the space occupied while ensuring connection strength.

[0112] The first pushing part 1221 moves upward from below the support 21 to push the aerosol generating article 22 out of the receiving hole 211, and the second pushing part 1222 moves downward from above the aerosol generating article 22 to push the aerosol generating article 22 back into the receiving hole 211. The outer diameter of the first pushing part 1221 is slightly smaller than the inner diameter of the receiving hole 211 at least at the end close to it, so that the first pushing part 1221 can partially enter the receiving hole 211 during the pushing of the aerosol generating article 22, thereby continuously providing a pushing force to the aerosol generating article 22.

[0113] The support part 2116 is located close to the second end face 215 in the depth direction of the receiving hole 211. This helps to limit the position of the aerosol generating product 22 when the second pushing part 1222 pushes it back into the receiving hole 211, thus stabilizing the position and posture of the aerosol generating product 22 after it returns to its original position.

[0114] Please see Figure 3 and Figure 4In some embodiments, the bracket has a notch 217 that penetrates the outer peripheral surface 216 and communicates with the receiving hole 211, and the notch 217 also penetrates the first end face 214 and the second end face 215.

[0115] The push rod 1223 includes a first connecting part 1231, a second connecting part 1232, and a connecting rod 1233. The first connecting part 1231 connects the first pushing part 1221 and one end of the connecting rod 1233. The second connecting part 1232 connects the second pushing part 1222 and the other end of the connecting rod 1233. Both the first connecting part 1231 and the second connecting part 1232 are bent relative to the connecting rod 1233. Under the drive of the pusher drive 121, the first connecting part 1231 can move in the notch 217.

[0116] Thus, the first connecting part 1231 connects one end of the first pushing part 1221 and the connecting rod 1233, and the second connecting part 1232 connects the other end of the second pushing part 1222 and the connecting rod 1233. Both the first connecting part 1231 and the second connecting part 1232 are bent relative to the connecting rod 1233. The first connecting part 1231 can move in the notch 217, thereby reducing the overall space occupied by the pushing part 122, making the structure more compact, which is conducive to the miniaturization of the aerosol generating device 10.

[0117] Specifically, the connecting rod 1233 can be rod-shaped, plate-shaped, or sheet-shaped. The connecting rod 1233 is disposed on one side of the radial direction of the receiving hole 211 outside the bracket 21, and can maintain the orientation in which the length direction of the connecting rod 1233 is parallel to the depth direction of the receiving hole 211. The first connecting part 1231 and the second connecting part 1232 can be rod-shaped, plate-shaped, sheet-shaped, or block-shaped structures, and this application does not impose any restrictions on them.

[0118] The first connecting portion 1231 and the second connecting portion 1232 are bent relative to the connecting rod 1233, and the bending angle can be any angle other than 0° and 180°. For example, the first connecting portion 1231 and the second connecting portion 1232 both form an angle of about 90° with the connecting rod 1233. The first connecting portion 1231 and the second connecting portion 1232 extend radially from both ends of the connecting rod 1233 along the receiving hole 211 or the bracket 21, respectively. The end of the first connecting portion 1231 is connected to the first pushing portion 1221, and the end of the second connecting portion 1232 is connected to the second pushing portion 1222.

[0119] As explained above, during the movement of the aerosol generating article 22, the first pushing part 1221 partially extends into the receiving hole 211. When the first pushing part 1221 partially extends into the receiving hole 211, the first connecting part 1231 is partially or completely accommodated in the notch 217 that communicates with the receiving hole 211 where the first pushing part 1221 is located, and the first connecting part 1231 moves in the notch 217 as the first pushing part 1221 moves.

[0120] In some embodiments, the second propulsion unit 1222 is a hollow tube (not shown).

[0121] Thus, since the second pushing part 1222 is a hollow tube, the aerosol formed by the aerosol generating product 22 can overflow along the second pushing part 1222 for suction.

[0122] Specifically, the aerosol generating device 10 includes a heating mechanism 13 for heating the aerosol generating matrix 221 and a suction nozzle 14 for user inhalation. The heating mechanism 13 has a heating chamber 131 communicating with the suction nozzle 14. A first pushing part 1221 pushes the aerosol generating product 22 out of the receiving hole 211 and pushes the aerosol generating product 22 into the heating chamber 131. A second pushing part 1222 communicates with the heating chamber 131 and the suction nozzle 14, so that the aerosol generated in the heating chamber 131 reaches the suction nozzle 14 through the second pushing part 1222.

[0123] Please see Figure 3 and Figure 4 In some embodiments, the pusher drive 121 includes a lead screw motor 1211, and a first pusher 1221 is sleeved on the lead screw 1212 of the lead screw motor 1211. The inner wall of the first pusher 1221 is provided with a thread that mates with the lead screw 1212.

[0124] Thus, through the threaded engagement between the first push part 1221 and the lead screw 1212 of the lead screw motor 1211, the lead screw motor 1211 can drive the first push part 1221, the push rod 1223 and the second push part 1222 to make linear motion as a whole through the rotation of the lead screw 1212. The structure and linkage method are simple, easy to manufacture and have high stability.

[0125] Specifically, the first pushing part 1221 can also be a hollow cylindrical or tubular structure. The first pushing part 1221 is sleeved on the lead screw 1212. The axial direction of the lead screw 1212 is consistent with the axial direction of the first pushing part 1221. Furthermore, the axial direction of the lead screw 1212 can be parallel to the depth direction of the receiving hole 211, so that when the lead screw motor 1211 is running, the rotation of the lead screw 1212 can drive the first pushing part 1221, the push rod 1223, and the second pushing part 1222 to move as a whole along the depth direction of the receiving hole 211.

[0126] Please see Figure 3 and Figure 4 In some embodiments, the aerosol generating device 10 includes a rotation drive mechanism 15, which includes a rotation drive member 151 and a drive shaft 152 connected to the rotation drive member 151. The rotation drive member 151 drives the bracket 21 to rotate relative to the heating mechanism 13 via the drive shaft 152, so that the receiving holes 211 are rotated one by one to a position axially opposite to the heating chamber 131 of the heating mechanism 13.

[0127] Thus, the rotation drive 151 drives the bracket 21 to rotate relative to the heating mechanism 13 via the drive shaft 152, so that the receiving holes 211 are rotated one by one to a position axially opposite to the heating chamber 131 of the heating mechanism 13, thereby realizing the rotational heating of the aerosol generation product 22, thereby increasing the number of suction ports, reducing the replacement frequency of the bracket 21 or aerosol generation consumables 20, and improving the user experience.

[0128] Specifically, the rotation drive mechanism 15 can drive the bracket 21 to rotate via electric drive, hydraulic drive, pneumatic drive, spring drive, or other means. As an example, the rotation drive 151 can be a drive motor, with the drive shaft 152 connected to the bracket 21. When the rotation drive 151 is running, the drive shaft 152 rotates, causing the bracket 21 to rotate. Furthermore, the drive shaft 152 is connected to the positioning structure 212, and the axial direction of the drive shaft 152 can coincide with the axial direction of the bracket 21, thereby causing the bracket 21 to rotate around its own center.

[0129] In some embodiments, a positioning structure 212 is provided at the center of the bracket 21, and the positioning structure 212 is configured to cooperate with the rotation drive mechanism 15 to rotate the bracket 21.

[0130] The positioning structure 212 is either a positioning hole 213 or a positioning shaft, and the drive shaft 152 is provided with a drive part 153 fixedly connected to the positioning structure 212. The drive part 153 is located at the end of the drive shaft 152 away from the rotation drive member 151. When the positioning structure 212 is a positioning hole 213, the drive part 153 is at least partially accommodated in the positioning hole 213. Furthermore, the shape and size of the drive part 153 are matched with the positioning hole 213, so that the peripheral surface of the drive part 153 is tightly engaged with the hole wall of the positioning hole 213, thereby enabling the drive shaft 152 to drive the bracket 21 to rotate through the cooperation of the drive part 153 and the positioning hole 213.

[0131] Optionally, the cross-section of the positioning structure 212 is one of polygonal, racetrack-shaped, elliptical, or quincunx-shaped.

[0132] Please see Figures 9-11In some embodiments, the heating mechanism 13 includes a conductive element 134 and a temperature sensing element 136. The conductive element 134 is electrically connected to the heating element 133. The temperature sensing element 136 is in contact with the conductive element 134 or the receiving element 132. The temperature sensing element 136 and the heating element 133 are spaced apart, and the minimum distance between the temperature sensing element 136 and the heating element 133 is less than or equal to 3 mm. The temperature sensing element 136 is used to detect the temperature of the heating mechanism 13.

[0133] Thus, by having the temperature sensing element 136 contact the conductive element 134 or the receiving element 132, and by having the temperature sensing element 136 and the heating element 133 spaced apart, and the minimum distance between the temperature sensing element 136 and the heating element 133 being less than or equal to 3mm, the temperature sensing element 136 can quickly and accurately reflect the temperature of the heating element 133, and the cost is low.

[0134] Specifically, the temperature sensing element 136 may include a thermocouple, a temperature sensing film, etc. The temperature sensing element 136 and the heating element 133 are not in direct contact and the minimum distance between the temperature sensing element 136 and the heating element 133 does not exceed 3mm, so as to reflect the temperature of the heating element 133.

[0135] It should be noted that the temperature reflected by the temperature sensing element 136 is not the actual temperature of the heating element 133, but rather the temperature measured at a relatively close distance to the heating element 133. It is a representation of the actual temperature of the heating element 133. By characterizing and providing feedback on the actual temperature of the heating element 133 through the temperature sensing element 136, the actual heating temperature can be accurately and promptly controlled, ensuring rapid heating while avoiding overheating and scorching, and optimizing the heating atomization effect.

[0136] The conductive element 134 may be a wire, a tube, a film, or other form of conductor.

[0137] Please see Figures 4-6 In some embodiments, the heating mechanism 13 includes a fixing component 135, which is fixedly connected to the receiving member 132. The conductive member 134 is fixedly disposed relative to the heating element 133 via the fixing component 135, and / or the heating element 133 is positioned relative to the receiving member 132 via the fixing component 135.

[0138] In this way, the positioning structure of the heating element 133 can be simplified, making it easier for the heating element 133 to be positioned in a suitable position on the receiving member 132, and the heating element 132 is not easily deformed, which is beneficial to improving the consistency of the heating mechanism 13.

[0139] Please see Figure 9 In some embodiments, the temperature sensing element 136 is a thermocouple, and the temperature sensing element 136 is welded or heat-fused to the conductive element 134.

[0140] In this way, the temperature sensing element 136 and the conductive element 134 form a solder joint or melting point. The position of the temperature sensing element 136 relative to the conductive element 134 and the heating element 133 is not affected by the assembly relationship or is minimally affected by the assembly relationship, thereby reducing the possibility of unstable temperature sensing position caused by assembly errors and improving temperature measurement accuracy.

[0141] Specifically, the conductive element 134 can be fixedly connected to the heating element 133. The temperature sensing element 136 includes a temperature sensing end 1361 for sensing temperature, and the temperature sensing end 1361 is located at the end of the temperature sensing element 136 near the heating element 133. One end of the temperature sensing element 136 with the temperature sensing end 1361 is welded or heat-fused to the conductive element 134, so that the temperature sensing end 1361 is close to the connection position between the temperature sensing element 136 and the conductive element 134, and the position of the temperature sensing end 1361 relative to the heating element 133 is fixed.

[0142] In some embodiments, the minimum distance D1 between the connection position of the temperature sensing element 136 and the conductive element 134 and the heating element 133 satisfies: 0.5mm≤D1≤3mm.

[0143] Thus, by setting the connection position of the temperature sensing element 136 and the conductive element 134 and the minimum distance D1 between them and the heating element 133 within a reasonable range, the relative positions of the temperature sensing element 136 and the heating element 133 are closer, resulting in higher timeliness and accuracy of temperature measurement. At the same time, the temperature sensing element 136 is less prone to high-temperature damage and the temperature resistance standard of the temperature sensing element 136 can be reduced, thereby lowering the cost.

[0144] Specifically, since the temperature sensing end 1361 is close to the connection point between the temperature sensing element 136 and the conductive element 134, the minimum distance D1 between the connection point of the temperature sensing element 136 and the conductive element 134 and the heating element 133 can be regarded as the minimum distance between the temperature sensing end 1361 and the heating element 133. Taking the welding of the temperature sensing element 136 and the conductive element 134 as an example, the connection point of the temperature sensing element 136 and the conductive element 134 is also the solder joint of the temperature sensing element 136 on the conductive element 134. The minimum distance D1 between the solder joint of the temperature sensing element 136 on the conductive element 134 and the heating element 133 can be 0.5mm, 0.8mm, 1.2mm, 1.7mm, 2.1mm, 2.6mm, or 3mm.

[0145] In some embodiments, the housing 132 is a metal tube (not shown), which surrounds a heating cavity 131. The temperature measuring end 1361 of the temperature measuring element 136 is welded to the outer wall of the metal tube, and the temperature measuring element 136 is disposed away from the heating element 133.

[0146] Thus, by welding the temperature measuring end 1361 of the temperature measuring element 136 to the outer wall of the metal tube, the metal tube forms a heating chamber 131, and the temperature measuring element 136 is set away from the heating element 133, so that the position of the temperature measuring element 136 relative to the heating element 133 is fixed and the distance is relatively close, which can ensure accurate and timely temperature measurement while avoiding problems such as high temperature damage to the temperature measuring element 136.

[0147] Specifically, the heating cavity 131 is formed inside the metal tube, and the heating element 133 and the temperature sensing element 136 are both disposed outside the metal tube. The temperature sensing end 1361 of the temperature sensing element 136 can be located at one end of the temperature sensing element 136, and the end of the temperature sensing element 136 away from the temperature sensing end 1361 can be used to connect the control component to provide feedback on the temperature of the temperature sensing end 1361, and to control the heating state of the heating element 133 through the control component.

[0148] In some embodiments, the minimum distance D2 between the connection position of the temperature sensing element 136 and the metal tube and the heating element 133 satisfies: 1mm≤D2≤3mm.

[0149] In this way, by setting the connection position of the temperature sensing element 136 and the metal tube and the minimum distance D2 between the temperature sensing element 133 and the heating element 133 within a reasonable range, the temperature sensing element 136 can be close enough to the heating wire. While ensuring the accuracy and timeliness of temperature measurement, it will not interfere with the temperature sensing element 136. It can also reduce the temperature resistance standard of the temperature sensing element 136 and reduce costs.

[0150] Specifically, the temperature sensing element 136 is welded to the metal tube. The connection position between the temperature sensing element 136 and the metal tube is also the solder joint of the temperature sensing element 136 on the metal tube. The minimum distance D1 between the solder joint of the temperature sensing element 136 on the metal tube and the heating element 133 can be 1mm, 1.1mm, 1.5mm, 2.3mm, 2.9mm, or 3mm.

[0151] Please see Figure 10 In some embodiments, the temperature sensing element 136 is enclosed by a sleeve 1364, which passes through and is engaged with a fixing assembly 135. The sleeve 1364 may be made of a high-temperature resistant material such as ceramic. The temperature sensing end 1361 of the temperature sensing element 136 may be at least partially exposed from the sleeve 1364.

[0152] Please see Figure 11 In some embodiments, the fixing component 135 includes a retainer 1351, and the temperature measuring element 136 includes a temperature measuring end 1361, two connecting parts 1362 and a receiving part 1363 connected in sequence. The temperature measuring end 1361 is close to the heating element 133, and the two connecting parts 1362 are spaced apart in the retainer 1351.

[0153] Thus, by bringing the temperature measuring end 1361 close to the heating element 133, the two connecting parts 1362 are connected to the temperature measuring end 1361 and spaced apart in the retaining member 1351, and the receiving part 1363 is connected to the two connecting parts 1362, thereby fixing the position of the temperature measuring end 1361 relative to the fixing component 135 and the heating element 133, which is beneficial to temperature measurement stability.

[0154] Specifically, the two connecting portions 1362 are separated from each other, and the temperature measuring end 1361 and the receiving portion 1363 are respectively connected to the two ends of the connecting portion 1362, so that the temperature measuring element 136 converges at both ends of the two connecting portions 1362. The receiving portion 1363 may form two interfaces for connection to the two connecting portions 1362 respectively.

[0155] Two connecting portions 1362 are spaced apart in the retaining member 1351, which can partially or completely accommodate the connecting portions 1362. Since the two ends of the two connecting portions 1362 are converging, the converging force at both ends causes the temperature sensing element 136 to engage with the retaining member 1351.

[0156] Please see Figure 11 In some embodiments, the retaining member 1351 is provided with two slots 1352 spaced apart, and two connecting parts 1362 are respectively passed through the two slots 1352. The retaining member 1351 also includes a separating part 1354 and a limiting part 1355 connected to the separating part 1354. The separating part 1354 is located between the two slots 1352, and the limiting part 1355 abuts against the temperature measuring end 1361 to limit the position of the temperature measuring end 1361.

[0157] Thus, with the partition 1354 located between the two slots 1352, and the limiting part 1355 connected to the partition 1354 and abutting against the temperature measuring end 1361, the position of the temperature measuring end 1361 and the connecting part 1362 is restricted, ensuring that the position of the temperature measuring end 1361 relative to the fixing component 135 and the heating element 133 is fixed, thereby improving the temperature measurement stability.

[0158] Specifically, the partition 1354 is located between the two connecting parts 1362, the limiting part 1355 forms an angle with the partition 1354, and the temperature measuring end 1361 can be located between the limiting part 1355 and the partition 1354.

[0159] Please see Figures 9-11 In some embodiments, the receiving member 132 is tubular, and the heating mechanism 13 includes an end cap 1356 and a support member 1359. The heating element 133 and the support member 1359 are sequentially sleeved on the outside of the receiving member 132, and the end cap 1356 is sleeved on both ends of the receiving member 132 along the axial direction and is fixedly connected to the support member 1359.

[0160] Thus, the heating element 133 and the support 1359 are sequentially sleeved on the outside of the receiving part 132, and the end cap 1356 is sleeved on both ends of the receiving part 132 along the axial direction and fixedly connected to the support 1359, thereby facilitating the assembly of the heating mechanism 13 as a whole, and providing a certain degree of protection and positioning for the receiving part 132 and the heating element 133.

[0161] Specifically, the support member 1359 is generally cylindrical or has a cylindrical structure. The support member 1359 covers the housing 132, the heating element 133, and the end cap 1356, facilitating the assembly of the heating mechanism 13 as a whole. The support member 1359 can be made of high-temperature resistant plastic, which helps to reduce manufacturing costs.

[0162] End cap 1356 is disposed between support member 1359 and receiving member 132 to prevent the receiving member 132 from overheating and melting support member 1359. End cap 1356 may be generally annular. Support member 1359, end cap 1356 and receiving member 132 may be coaxially assembled. Unless otherwise specified, "axial" in the following text refers to the common axial direction of receiving member 132, end cap 1356 and support member 1359.

[0163] The end cap 1356 and the receiving member 132 can be fixed by adhesive bonding or interference fit. The support member 1359 and the receiving member 132 are radially spaced, and the heating element 133 is located within the space between the support member 1359 and the receiving member 132. The end cap 1356 can cover the space between the support member 1359 and the receiving member 132. Adhesive can be applied between the end cap 1356 and the receiving member 132 to improve sealing and prevent aerosols from entering the vicinity of the heating element 133 and affecting the heating effect.

[0164] The wall thickness of end cap 1356 can range from 0.3mm to 1mm, thus achieving a thinner wall thickness and lower heat capacity while ensuring strength, which is beneficial for energy saving. End cap 1356 can be made of materials such as ceramics and zirconium oxide to ensure good heat resistance and structural strength.

[0165] Please see Figure 8 In some embodiments, the heating mechanism 13 includes a conductive element 134 electrically connected to the heating element 133, and the end cap 1356 is provided with a wire outlet groove 1358. The conductive element 134 passes through two wire outlet grooves 1358 respectively and is fixedly connected to the heating element 133.

[0166] Thus, the end cap 1356 provides a wire outlet groove 1358, through which the conductive element 134 passes and is fixedly connected to the heating element 133, thereby limiting the axial position of the conductive element 134 relative to the heating element 133.

[0167] Please see Figures 9-11In some embodiments, the heating element 133 has a first connecting end 1331 and a second connecting end 1332 at its two axial ends on the receiving member 132, and the heating element 133 extends spirally between the first connecting end 1331 and the second connecting end 1332.

[0168] The conductive element 134 includes a first conductive end 1341 connected to the first connecting end 1331 and a second conductive end 1342 connected to the second connecting end 1332. The first conductive end 1341 and the second conductive end 1342 extend along the extension line of the extension path of the heating element 133 on the outer surface of the receiving element 132. The first conductive end 1341 and the second conductive end 1342 are respectively inserted into two wire outlet grooves 1358.

[0169] Thus, by spirally extending the heating element 133 between the first connecting end 1331 and the second connecting end 1332, and by winding the first conductive end 1341 and the second conductive end 1342 around the surface of the receiving member 132 for a period of time before leading them outward, high temperature damage to the fixing component 135 can be avoided, the temperature resistance requirements of the fixing component 135 can be reduced, and the cost can be reduced.

[0170] Furthermore, since the first conductive end 1341 and the second conductive end 1342 are axially positioned through the wire outlet groove 1358, the positions of the first connecting end 1331 and the second connecting end 1332 can be limited by restricting the axial positions of the first conductive end 1341 and the second conductive end 1342. The degree of contact between the heating element 133 and the receiving member 132 can be adjusted by tightening or loosening the conductive member 134, so that the heating element 133 can be closely attached to the outer surface of the receiving member 132, thereby improving the effective utilization rate of heat.

[0171] Specifically, the heating element 133, the first conductive end 1341, and the second conductive end 1342 are spirally wound around the outer surface of the receiving member 132. The heating element 133, the first conductive end 1341, and the second conductive end 1342 can be connected as a whole, and the heating element 133, the first conductive end 1341, and the second conductive end 1342 are integrally solenoid-shaped. It is easy to understand that when the two ends of the solenoid are clamped in the axial direction, the solenoid can contract radially. Therefore, the first conductive end 1341 and the second conductive end 1342 pass through the wire outlet grooves 1358 located at the two ends of the receiving member 132 in the axial direction, which can fix the axial position of the heating element 133 and adjust the degree of contact between the heating element 133 and the receiving member 132.

[0172] Please see Figures 9-11In some embodiments, the end cap 1356 includes a first end cap 1356aa and a second end cap 1356bb. The first end cap 1356aa and the second end cap 1356bb are respectively sleeved on both ends of the axial direction of the receiving member 211. The first end cap 1356aa and the second end cap 1356bb are both provided with hook-shaped portions 1357. The hook-shaped portions 1357 protrude from the opposite end faces of the first end cap 1356aa and the second end cap 1356bb. The wire outlet groove 1358 is formed on the hook-shaped portions 1357.

[0173] Thus, the first conductive end 1341 and the second conductive end 1342 pass through the two wire outlet grooves 1358 respectively and are connected to the two ends of the heating element 133 in the axial direction. The hook-shaped part 1357 protrudes from the end faces of the first end cover 1356aa and the second end cover 1356bb that are opposite each other in the axial direction, thereby restricting the axial position of the first conductive end 1341 and the first connecting end 1331, the second conductive end 1342 and the second conductive end 1342.

[0174] Specifically, the hook-shaped portion 1357 may first extend axially from the end face of the end cap 1356 toward the other end cap 1356, then bend and continue to extend circumferentially along the end cap 1356.

[0175] Optionally, the hook-shaped portion 1357 and the end face of the end cap 1356 to which it is connected together form a wire outlet groove 1358, and the opening of the wire outlet groove 1358 is formed on one side of the hook-shaped portion 1357 along the circumference of the end cap 1356. In this way, the first conductive end 1341 and the second conductive end 1342 are axially limited in the wire outlet groove 1358, and the first conductive end 1341 or the second conductive end 1342 is further prevented from slipping out of the wire outlet groove 1358.

[0176] The orientation of the slot 1358 on the first end cover 1356aa can be opposite to the orientation of the slot 1358 on the second end cover 1356bb in the circumferential direction.

[0177] The leads 1343 connected to the first conductive terminal 1341 and the second conductive terminal 1342 can be connected to the positive and negative terminals of the power supply or power supply circuit, respectively. The axial spacing between the first conductive terminal 1341 and the second conductive terminal 1342 can also reduce the risk of short circuit. Furthermore, the conductive component 134 also includes an insulating layer, which covers the leads to enhance the insulation protection strength.

[0178] Optionally, such as Figure 8 As shown, the heat insulation component 137 is provided with two wire-passing grooves 1371 at intervals. The lead wires 1343 connected to the first conductive end 1341 and the second conductive end 1342 pass through the two wire-passing grooves 1371 on the heat insulation component 137, respectively. Optionally, some of the lead wires 1343 of the conductive component 134 can be fixed in the wire-passing grooves 1371 by applying adhesive.

[0179] In some embodiments, the heating mechanism 13 includes an adhesive element (not shown) disposed in the wire outlet groove 1358 and used to bond the conductive element 134 to the groove wall of the wire outlet groove 1358. Thus, by bonding the conductive element 1334 to the groove wall of the wire outlet groove 1358 with the adhesive element, the axial wire outlet position of the conductive element 134 is further stabilized. Specifically, the adhesive element can be an insulating adhesive. The adhesive element can be a film layer or a dot-like form.

[0180] Please see Figure 8 and Figure 11 In some embodiments, at least one end cap 1356 is provided with a first heat insulation portion 1374, the first heat insulation portion 1374 including a plurality of spaced first protrusions 1374a, the first protrusions 1374a protruding from the surface of the end cap 1356 toward the receiving member 132 and abutting against the outer peripheral surface of the receiving member 132.

[0181] Thus, by having the first protrusion 1374a protrude from the surface of the end cap 1356 toward the receiving member 132 and abut against the outer peripheral surface of the receiving member 132, the contact area between the end cap 1356 and the receiving member 132 is reduced, and the heat capacity of the end cap 1356 itself is reduced, thereby reducing the heat absorption of the end cap 1356 and improving the heating efficiency and heating speed inside the heating mechanism 13.

[0182] Specifically, both the first end cap 1356a and the second end cap 1356b may be provided with a first heat insulation portion 1374; or, the first end cap 1356a may be provided with a first heat insulation portion 1374, and the inner circumferential surface of the second end cap 1356b may be directly attached to the outer circumferential surface of the receiving member 132; or, the second end cap 1356b may be provided with a first heat insulation portion 1374, and the inner circumferential surface of the first end cap 1356a may be directly attached to the outer circumferential surface of the receiving member 132.

[0183] Multiple first protrusions 1374a may be evenly distributed along the circumference of the receiving member 132, and the protrusions of the multiple first protrusions 1374a from the end cap 1356 may be of equal size. The multiple first protrusions 1374a may surround the receiving member 132, or may be provided only locally on the surface of the end cap 1356 facing the receiving member 132. The first protrusions 1374a abut against the outer peripheral surface of the receiving member 132, which is an arc surface that fits against the outer peripheral surface of the receiving member 132.

[0184] Please see Figure 8 In some embodiments, at least one end cap 1356 is provided with a second heat insulation portion 1375, the second heat insulation portion 1375 includes a plurality of spaced second protrusions 1375a, the second protrusions 1375a protrude from the surface of the end cap 1356 toward the support member 1359 and abut against the inner peripheral surface of the support member 1359.

[0185] Thus, by having the second protrusion 1375a protrude from the surface of the end cap 1356 toward the support member 1359 and abut against the inner circumferential surface of the support member 1359, the contact area between the end cap 1356 and the support member 1359 is reduced, and the heat capacity of the end cap 1356 itself is also reduced, thereby reducing the heat transfer from the end cap 1356 to the outside and improving the heating efficiency and heating speed inside the heating mechanism 13.

[0186] Specifically, both the first end cap 1356a and the second end cap 1356b may be provided with a second heat insulation portion 1375; or, the first end cap 1356a may be provided with a second heat insulation portion 1375, and the outer peripheral surface of the second end cap 1356b may be directly fitted with the inner peripheral surface of the support member 1359; or, the second end cap 1356b may be provided with a second heat insulation portion 1375, and the outer peripheral surface of the first end cap 1356a may be directly fitted with the inner peripheral surface of the support member 1359.

[0187] The plurality of second protrusions 1375a may be evenly distributed along the circumference of the receiving member 132, and the protrusions of the plurality of second protrusions 1375a out of the end cap 1356 may be of equal size. The plurality of second protrusions 1375a may surround the end cap 1356 for a full circumference, or may be provided only locally on the surface of the end cap 1356 facing the support member 1359. For example, the plurality of second protrusions 1375a may surround half a circumference, three-quarters of a circumference, or one-third of a circumference of the end cap 1356.

[0188] In one specific embodiment, the aerosol generating device 10 includes a top cover that fits onto one end of a support member 1359 along the axial direction. The top cover and a first end cover 1356a together seal the space between the receiving member 132 and the support member 1359 at one end of the support member 1359. The top cover may be disposed on the side of the support member 1359 opposite to the bracket 21. In this embodiment, the first end cover 1356a has a first heat insulation portion 1374, and the second end cover 1356b has a second heat insulation portion 1375.

[0189] Please see Figures 6-8 In some embodiments, the heating mechanism 13 includes a conductive element 134 and a heat insulation element 137. The conductive element 134 is electrically connected to the heating element 133, and the portion of the conductive element 134 near the heating element 133 passes through the heat insulation element 137.

[0190] Thus, by having the portion of the conductive element 134 near the heating element 133 pass through the heat insulation element 137, the exposed conductive element 134 is prevented from overheating and melting other components it comes into contact with, thereby reducing the risk of structural failure or the generation of odors.

[0191] Specifically, the heat insulation component 137 can have various structures such as plate-shaped, block-shaped, and cylindrical. The heat insulation component 137 can be made of high-temperature resistant ceramic.

[0192] Taking the conductive component 134 as a wire and the heat insulation component 137 as a plate structure as an example, a wire-passing groove 1371 can be formed on the heat insulation component 137. The end of the conductive component 134 is connected to the heating element, and then passes through the wire outlet groove and the wire-passing groove 1371 in sequence to pass through the fixing component.

[0193] Optionally, the heat insulation component 137 can be fixedly connected to the support component 1359 by at least one of the following methods: snap-fit ​​connection, sintering, screwing, riveting, adhesive connection, etc.

[0194] Please see Figures 6-8 In some embodiments, the heating mechanism 13 includes a support member 1359. The heating element 133 and the support member 1359 are sequentially sleeved outside the receiving member 132. The support member 1359 has a mounting groove 1372 that extends radially through the wall of the support member 1359. A heat insulation member 137 is disposed in the mounting groove 1372. This enhances the connection strength between the heat insulation member 137 and the support member 1359, and the heat insulation member 137 isolates the contact between the conductive element 134 and the support member 1359, thereby providing heat insulation protection for the support member 1359.

[0195] Specifically, the inner contour shape of the mounting groove 1372 matches the outer contour shape of the heat insulation component 137, and the outer surface of the heat insulation component 137 can be tightly fitted and fixedly connected to the groove wall of the mounting groove 1372. Furthermore, the heat insulation component 137 can be embedded in the mounting groove 1372. For example, the heat insulation component 137 is a square plate, and the mounting groove 1372 is a square groove.

[0196] In addition, the portion of the conductive element 134 that passes through the heat insulation element 137 also passes through the mounting groove 1372, so that the conductive element 134 passes through the wall of the support element 1359. This simplifies the wiring layout, saves space, and further limits the position of the conductive element 134.

[0197] Please see Figure 4 and Figure 5 In some embodiments, the receiving member 132, the end cap 1356 and the support member 1359 are all formed with through holes on the side facing the bracket 21. One of the plurality of receiving holes 211 is opposite to and communicates with the heating chamber 131 along the axial direction of the receiving member 132. The edge of the through hole of at least one of the three members 132, the end cap 1356 and the support member 1359 is provided with a guide structure 139. The guide structure 139 includes an inclined surface 1390 that forms an angle with the depth direction of the receiving hole 211.

[0198] Thus, by providing a guide structure 139 to the through hole edge of the receiving hole 211 by at least one of the three components—the receiving member 132, the end cap 1356, and the support member 1359—the guide structure 139 includes an inclined surface 1390 that forms an angle with the depth direction of the receiving member 132. This avoids the step surface from blocking the movement of the aerosol generating product 22 due to manufacturing errors, thus preventing jamming and other adverse phenomena. It also helps the aerosol generating product 22 to be smoothly pushed from the receiving hole 211 into the heating chamber 131 or withdrawn from the heating chamber 131 back into the receiving hole 211.

[0199] Specifically, as explained above, the depth direction of the receiving hole 211 is also the direction in which the aerosol-generating product 22 moves between the heating chamber 131 and the receiving chamber. Taking the direction from the heating mechanism 13 to the support 21 along the depth direction of the receiving hole 211 as the top-to-bottom direction, when the receiving member 132 is tubular, the support member 1359 is cylindrical, and the end cap 1356 is annular, the receiving member 132, the end cap 1356, and the support member 1359 are all coaxial with the receiving hole 211 directly below the heating mechanism 13. The depth direction of the receiving hole 211 is also the axial direction of the receiving member 132, the end cap 1356, and the support member 1359.

[0200] In some embodiments, the angle formed by the inclined surface 1390 and the depth direction of the receiving hole 211 is greater than 0° and less than 45°.

[0201] Thus, by setting the angle between the inclined plane 1390 and the depth direction of the receiving hole 211 within a reasonable range, the movement of the aerosol-generated product 22 is ensured to proceed smoothly.

[0202] Specifically, when two or more of the three components 132, 1356 and 1359 are provided with guide structures 139, the angles formed by the inclined surfaces 1390 of the different guide structures 139 and the depth direction of the receiving hole 211 can be the same or different.

[0203] Please see Figure 4 In some embodiments, the two ends of the receiving member 132 are formed with insertion holes 138 communicating with the heating chamber 131, and the insertion holes 138 are opposite to one of the plurality of receiving holes 211 along the depth direction of the receiving hole 211.

[0204] Thus, by having the insertion hole 138 opposite one of the plurality of receiving holes 211 along the depth direction of the receiving hole 211, it is convenient for the feeding mechanism to push the aerosol generating article 22 to move between the heating chamber 131 and the receiving hole 211.

[0205] Specifically, the depth direction of the receiving hole 211 can be parallel to the axial direction of the receiving member 132, and the receiving hole 211 opposite to the insertion hole 138 can be coaxially opposite to the heating cavity 131 and communicate with the heating cavity 131 through the insertion hole 138.

[0206] Please see Figure 5 and Figure 11 In some embodiments, the guide structure 139 includes a first guide structure 1391, which is disposed at the edge of the insertion hole 138 of the receiving member 132 facing the bracket 21. The outer diameter of the first guide structure 1391 is larger than the inner diameter of the receiving member 132. The first guide structure 1391 includes a first inclined surface 139a, which forms a first angle with the depth direction of the receiving hole 211. The first angle α satisfies: 0° < α < 45°.

[0207] Furthermore, 25°≤α≤35°, for example, the first included angle α can be 25°, 27.3°, 29°, 32°, or 35°.

[0208] Please see Figure 5 In some embodiments, when the aerosol generating article 22 enters the heating chamber 131, the end of the aerosol generating article 22 does not exceed the first guide structure 1391 along the depth direction of the receiving hole 211. That is, during the movement of the aerosol generating article 22 between the receiving hole 211 and the heating chamber 131, the lower end of the aerosol generating article 22 is always below the first guide structure 1391, or at least flush with it, along the depth direction of the receiving hole 211. This prevents the aerosol generating article 22 from being stuck by the guide structure 1391 when it is pushed back from the heating chamber 131 into the receiving hole 211.

[0209] Please see Figure 5 and Figure 11 In some embodiments, the end cap 1356 near the bracket 21 is provided with a second guide structure 1392. The second guide structure 1392 forms a second inclined surface 139b facing the receiving hole 211. The second inclined surface 139b forms a second included angle with the depth direction of the receiving hole 211. The second included angle β satisfies: 0°<β<45°.

[0210] Specifically, the second guide structure 1392 is formed on the side of the second end cap 1356b facing the bracket 21, and the second guide structure 1392 and the edge of the insertion hole 138 of the receiving member 132 facing the bracket 21 are spaced along the depth direction of the receiving hole 211. The second end cap 1356b is generally annular, and the second guide structure 1392 can be formed by the second inclined surface 139b surrounding the end cap 1356. Optionally, 25°≤β≤35°, for example, the second included angle β can be 25°, 26°, 28°, 31.5°, or 35°.

[0211] Please see Figure 5 and Figure 11 In some embodiments, the support member 1359 has a third guide structure 1393 at one end facing the bracket 21. The third guide structure 1393 and the edge of the insertion hole 138 of the receiving member 132 facing the bracket 21 are spaced along the depth direction of the receiving hole 211. The third guide structure 1393 forms a third inclined surface 139c facing the receiving hole 211. The third inclined surface 139c and the depth direction of the receiving hole 211 form a third angle γ, which satisfies: 0° < γ < 45°.

[0212] Furthermore, 25°≤γ≤35°, for example, the third included angle γ can be 25°, 28°, 30°, 33°, or 35°.

[0213] Thus, the third guide structure 1393 ensures that the movement of the aerosol-generated product 22 from the support 21 into the heating mechanism 13 can proceed smoothly even if there is an axial deviation between the receiving hole 211 or the support 21 and the heating chamber 131.

[0214] Please see Figure 5 and Figure 11 In some embodiments, the receiving member 132 is provided with a first guide structure 1391 facing the edge of the insertion hole 138 of the bracket 21, the end cap 1356 is provided with a second guide structure 1392, and the support member 1359 is provided with a third guide structure 1393. The first guide structure 1391, the second guide structure 1392, and the third guide structure 1393 all include a slope 1390 that forms an angle with the depth direction of the receiving hole 211. The first guide structure 1391, the second guide structure 1392, and the third guide structure 1393 are arranged sequentially at intervals along the depth direction of the receiving hole 211.

[0215] Among them, the inner diameter of one of the three guide structures 1391, 1392 and 1393 is smaller than the other two, and the minimum inner diameter of the three guide structures 1391, 1392 and 1393 is greater than the outer diameter of the aerosol generating product 22.

[0216] Thus, the inner diameter of one of the three guide structures 1391, 1392 and 1393 is smaller than the other two, and the inner diameter of the guide structure 139 is still larger than the outer diameter of the aerosol generating product 22. This is conducive to the transitional fit between the aerosol generating product 22 and the guide structure 139, so that the aerosol generating product 22 can be stopped at the desired heating position by friction, avoiding uncontrolled movement that would lead to uncontrolled atomization effect.

[0217] Please refer to it again. Figure 2The aerosol generation system 100 of this application includes the aerosol generation apparatus 10 of any of the above embodiments and at least one aerosol generation article 22.

[0218] The aerosol generation system 100 of this application includes the aerosol generation device 10 of any of the above embodiments, and therefore has all the beneficial effects of the above embodiments.

[0219] The aerosol generating product 22 in the support 21 is pushed out of the support 21 by the pushing mechanism. The heating mechanism 13 heats the aerosol generating product 22 that has been removed from the support 21. The pushing mechanism then pushes the aerosol generating product 22 back into the support 21. Thus, the heating mechanism 13 can sequentially heat the aerosol generating products 22 that have been removed from different receiving holes 211, increasing the number of continuous suction ports and reducing the replacement frequency of the aerosol generating consumable 20.
