Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically, to a heating mechanism 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, aerosol generating devices include a heating mechanism for generating heat. This mechanism includes a heating element and a conductive component electrically connected to the heating element. The conductive component serves both to power the heating element and to fix its position. However, the conductive component is prone to overheating during heating, especially when the maximum operating temperature of the heating element can reach around 1000°C. Excessive temperature can melt other components in contact with the conductive component, leading to fixation failure or the generation of unpleasant odors. Utility Model Content

[0003] This application provides a heating mechanism and an aerosol generating device.

[0004] The heating mechanism in the embodiments of this application includes:

[0005] A container having a heating chamber for containing an aerosol-generated product;

[0006] A heating element is disposed on a housing and is used to heat the aerosol-generated product.

[0007] The conductive component is electrically connected to the heating element, and the portion of the conductive component near the heating element is inserted into the heat insulation component.

[0008] The heating mechanism of this application embodiment has the portion of the conductive part close to the heating element inserted into the heat insulation part, thereby avoiding the exposed conductive part from getting too hot and melting other parts in contact, thus reducing the risk of structural failure or odor generation.

[0009] In some embodiments, the heating mechanism further includes a fixing component, which includes an end cap and a support member. The support member is sleeved outside the receiving member, and the end cap is sleeved at both ends of the receiving member along the axial direction and fixedly connected to the support member. The end cap is provided with a wire outlet groove, through which a conductive element passes and is fixedly connected to the heating element.

[0010] Thus, the heating element and the support are sequentially fitted outside the receiving part, and the end cap is fitted on both ends of the receiving part along the axial direction and fixedly connected to the support. The end cap is provided with a wire outlet groove, and the conductive part passes through the wire outlet groove and is fixedly connected to the heating element, thereby restricting the axial position of the conductive part relative to the heating element.

[0011] In some embodiments, the support member is formed with a mounting groove that extends radially through the wall of the support member, and a heat insulation member is disposed in the mounting groove.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] In some embodiments, the hook-shaped portion and the end face of the end cap to which it is connected together form a cable outlet groove, and the opening of the cable outlet groove is formed on the surface of the hook-shaped portion along the circumferential side of the end cap.

[0016] 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.

[0017] In some embodiments, the heating element has a first connecting end and a second connecting end at its two ends in the axial direction of the housing, and the heating element extends spirally between the first connecting end and the second connecting end.

[0018] Thus, by spiraling between the first and second connecting ends, the heating element can be spirally tightened and pressed against the outer surface of the receiving component, thereby improving the effective utilization rate of heat.

[0019] In some embodiments, the conductive element 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 an outlet groove.

[0020] Thus, the first conductive end is connected to the first connecting end, and the second connecting end is connected to the second connecting end. The first and second conductive ends extend spirally along the extension path of the heating element on the outer surface of the housing. 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 the axial positions of the first and second conductive ends. The fit between the heating element and the housing can be adjusted by tightening or loosening the conductive parts. In addition, 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 can reduce the temperature of the conductive parts when passing through the heat insulation part, further reducing the impact on other components.

[0021] In some embodiments, the heating mechanism includes an adhesive component disposed in the wire outlet groove and used to bond the conductive component to the groove wall.

[0022] In this way, the conductive component is bonded to the wall of the outlet groove by adhesive, thereby further ensuring the stability of the axial outlet position of the conductive component.

[0023] An aerosol generating apparatus, comprising:

[0024] Heating mechanism of any of the above embodiments;

[0025] The support has multiple receiving holes for accommodating aerosol-generated products; and

[0026] The feeding mechanism includes a feeding drive and a pushing member. The feeding drive is used to drive the pushing member to move along the depth direction of the receiving hole, so that the pushing member pushes the aerosol-generated product in the receiving hole out of the receiving hole, or pushes the aerosol-generated product located outside the receiving hole back into the receiving hole.

[0027] The aerosol generating apparatus according to the present application has the heating mechanism of any of the above embodiments, and therefore has all the beneficial effects of the above embodiments.

[0028] In some embodiments, the receiver is tubular, and its two axial ends are formed with insertion holes that communicate with the heating chamber. The insertion holes are opposite to one of the plurality of receiver holes along the depth direction of the receiver hole.

[0029] Thus, by having the insertion hole aligned with one of the multiple receiving holes along the depth direction of the receiving hole, the feeding mechanism can easily move the aerosol-generated product between the heating chamber and the receiving hole.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] Please see Figures 6-8 This application provides a heating mechanism 13, which includes a receiving member 132, a heating element 133, a conductive member 134, and a heat insulation member 137. The receiving member 132 forms a heating cavity 131 for receiving an aerosol generating product 22. The heating element 133 is disposed on the receiving member 132 and is used to heat the aerosol generating product 22. The conductive member 134 is electrically connected to the heating element 133, and the portion of the conductive member near the heating element passes through the heat insulation member 137.

[0071] The heating mechanism 13 of this application embodiment is applied to a type of aerosol generating device 100 that requires rapid aerosol generation, and is particularly suitable for a circumferential heating structure, but is not limited to the aerosol generating device 100 with interchangeable heating listed in the embodiments of this application.

[0072] In this embodiment, the heating mechanism 13 passes through the heat insulation member 137 via the portion of the conductive member 134 near the heating element 133, thereby preventing the exposed conductive member 134 from overheating and melting other components in contact, thus reducing the risk of structural failure or odor generation.

[0073] Specifically, the receiving element 132 can be a hollow structure, and the hollow section of the receiving element 132 forms a heating cavity 131. The receiving element 132 can be made of materials such as metal, ceramic, or high-temperature resistant glass. The conductive element 134 can be a wire, tube, film, or other form of conductor. The heat insulation element 137 can have various structures such as plate, block, or cylinder. The heat insulation element 137 can be made of high-temperature resistant ceramic.

[0074] Please see Figure 7 and Figure 8 In some embodiments, the fixing component 135 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. 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. The end cap 1356 is provided with a wire outlet groove 1358. The conductive element 134 passes through the wire outlet groove 1358 and is fixedly connected to the heating element 133.

[0075] Thus, 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 fixedly connected to the support member 1359. The end cap 1356 is provided with a wire outlet groove 1358, and the conductive member 134 passes through the wire outlet groove 1358 and is fixedly connected to the heating element 133, thereby restricting the axial position of the conductive member 134 relative to the heating element 133.

[0076] Specifically, the housing 132 is tubular, and the support 1359 is generally cylindrical or has a cylindrical structure. The support 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 1359 can be made of high-temperature resistant plastic, which helps to reduce manufacturing costs.

[0077] 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.

[0078] 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.

[0079] 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. However, if it is too thin, there is a risk of damage from drops. End cap 1356 can be made of materials such as ceramics and zirconium oxide to ensure good heat resistance and structural strength.

[0080] 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.

[0081] 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.

[0082] Please see Figures 6-8 In some embodiments, the support member 1359 has a mounting groove 1372 that extends radially through the wall of the support member 1359, and 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 also isolates the contact between the conductive member 134 and the support member 1359, thereby providing heat insulation protection for the support member 1359.

[0083] 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.

[0084] 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.

[0085] Please see Figures 9-11 In some embodiments, the heating element 133 has a first connecting end 1331 and a second connecting end 1332 at its two axial ends of the receiving member 132, and the conductive member 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.

[0086] The end cap 1356 includes a first end cap 1356a and a second end cap 1356b that are axially opposite to each other along the receiving member 132. Each of the first end cap 1356a and the second end cap 1356b is provided with a hook-shaped portion 1357, which forms a wire outlet groove 1358. The first conductive end 1341 and the second conductive end 1342 are respectively inserted into the two wire outlet grooves 1358.

[0087] 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, thereby restricting the axial position of the first conductive end 1341, the first connecting end 1331, the second conductive end 1342 and the second conductive end 1342.

[0088] Specifically, the hook-shaped portion 1357 protrudes from the axially opposite end faces of the first end cap 1356a and the second end cap 1356b. 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.

[0089] 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.

[0090] The orientation of the slot 1358 on the first end cover 1356a can be opposite to the orientation of the slot 1358 on the second end cover 1356b in the circumferential direction.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] Please see Figures 9-11In some embodiments, the heating element 133 extends spirally between the first connection end 1331 and the second connection end 1332, and 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 accommodating member 132.

[0095] Thus, by spirally extending the heating element 133 between the first connecting end 1331 and 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, and the first conductive end 1341 and the second conductive end 1342 are axially positioned through the wire outlet groove 1358, so that the heating element 133 can be spirally tightened and closely attached to the outer surface of the receiving part 132, thereby improving the effective utilization rate of heat.

[0096] In addition, the first conductive end 1341 and the second conductive end 1342 are wrapped around the surface of the receiving member 132 for a period of time before being led outward, which can avoid high temperature damage to the fixing component 135, reduce the temperature resistance requirements of the fixing component 135, and reduce costs.

[0097] 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.

[0098] Please refer to 6- Figure 11 In some embodiments, the heating mechanism 13 further includes a temperature sensing element 136, which is in contact with the conductive element 134 or the receiving element 132. The temperature sensing element 136 is spaced apart from the heating element 133, 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 element 133.

[0099] In the heating mechanism 13 of this application embodiment, the temperature measuring element 136 contacts the conductive element 134 or the receiving element 132. The temperature measuring element 136 and the heating element 133 are spaced apart, and the minimum distance between the temperature measuring element 136 and the heating element 133 is less than or equal to 3mm. Thus, the temperature measuring element 136 can quickly and accurately reflect the temperature of the heating element 133, and the cost is low.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] Please see Figure 7 and Figure 10 In some embodiments, a fixing component 135 is fixedly connected to a receiving member 132, a conductive member 134 is fixedly disposed relative to a 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.

[0104] 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.

[0105] Please see Figure 9 In some embodiments, the temperature sensing element 136 is welded or heat-fused to the conductive element 134.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] Optionally, the retaining member 1351 is fixedly connected to the end cap 1356. Further, the retaining member 1351 is disposed on the hook-shaped portion 1357 of one of the end caps 1356. For example, the two hook-shaped portions 1357 of the first end cap 1356a and the second end cap 1356b are opposite each other along the axial direction of the receiving member 132, and the retaining member 1351 protrudes from the opposite end face of the second end cap 1356b toward the first end cap 1356a. That is, the retaining member 1351 is located between the two hook-shaped portions 1357 of the first end cap 1356a and the second end cap 1356b, and the temperature measuring end 1361 is also located axially between the first electrical terminal and the second electrical terminal of the receiving member 132.

[0126] In some embodiments, the heating element 133 is a thermocouple. This allows the heating element 133 to withstand a wider temperature range and provides more accurate temperature measurement. Specifically, the upper limit of the temperature measurement range of the heating element 133 can exceed 1300°C.

[0127] Please see Figure 4 This application provides an aerosol generating apparatus 10, which includes:

[0128] Heating mechanism 13 of any of the above embodiments;

[0129] The support 21 has multiple receiving holes 211 for receiving aerosol-generated articles 22; and

[0130] The pushing mechanism 12 includes a pushing drive 121 and a pushing member 122. The pushing 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.

[0131] The aerosol generating apparatus 10 of this application embodiment has the heating mechanism 13 of any of the above embodiments, and therefore has all the beneficial effects of the above embodiments.

[0132] Please see Figure 4 and Figure 7 In some embodiments, the receiving member 132 is tubular, and the two ends of the receiving member 132 are formed with insertion holes 138 communicating with the heating chamber 131. The insertion holes 138 are opposite to one of the plurality of receiving holes 211 along the depth direction of the receiving hole 211.

[0133] 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, the feeding mechanism 12 can push the aerosol generating article 22 to move between the heating chamber 131 and the receiving hole 211.

[0134] 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.

[0135] Please see Figure 12 and Figure 17 In some embodiments, a positioning structure 212 is provided at the center of the support 21. The positioning structure 212 is an axisymmetric structure and is configured to rotate the support 20.

[0136] The bracket 21 of this embodiment is used to be installed in the aerosol generating device 10 to stabilize the position of the aerosol generating product 22. The bracket 21 has a positioning structure 212 at its center to facilitate the positioning and installation of the bracket 212. The positioning structure 212 is an axisymmetric structure that allows the bracket 21 to rotate, so that multiple aerosol generating products 22 can rotate with the bracket to achieve alternating heating, thereby increasing the number of effective suction ports and improving ease of use.

[0137] 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.

[0138] 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.

[0139] The positioning structure 212 is an axisymmetric structure, meaning that its cross-sectional shape can be folded and overlapped along a certain axis. The positioning structure 212 is located at the center of the support 21, allowing the support 21 to rotate around the position of the positioning structure 212. Multiple receiving holes 211 can be distributed around the center of the support 21. During the rotation of the support 21 by the positioning structure 212, each receiving hole 211 can sequentially rotate to the position of an adjacent receiving hole 211, thereby replacing the heated aerosol-generated product 22 with a fresh aerosol-generated product 22.

[0140] In some embodiments, the support 21 is made of high-temperature resistant plastic, ceramic, or paper. This provides the support 21 with better temperature resistance, reducing the risk of deformation, odor, and damage caused by high temperatures, thus improving its lifespan and safety.

[0141] Please see Figure 17 In some embodiments, the positioning structure 212 is a positioning hole 213 or a positioning shaft (not shown in the figure), and the cross-section of the positioning structure 212 is one of polygonal, racetrack-shaped, elliptical, or plum blossom-shaped.

[0142] Thus, the positioning hole 213 is formed by a recess in the surface of the bracket 21, freeing up some space for other components, making the structure more compact and facilitating product miniaturization. The positioning shaft can protrude relative to the surface of the bracket 21, facilitating the cooperation of the positioning structure 212 with other components.

[0143] In some embodiments, the cross-sectional area of ​​the positioning hole 213 is rectangular, such as... Figure 17 In the example, the cross-sectional area of ​​the positioning hole 213 is pentagonal.

[0144] Please see Figure 12 and Figure 17 In some embodiments, the support 21 is cylindrical, and there are multiple receiving holes 211. The multiple receiving holes 211 are spaced apart along the circumference of the support 21. The cross-section of the positioning structure 212 is polygonal, and along the radial direction of the support 21, one side of the polygon is aligned with the center of one of the receiving holes 211.

[0145] Thus, the radial direction of one edge of the polygonal bracket 21 is aligned with the center of one of the receiving holes 211, thereby facilitating the assembly and positioning of the bracket 21 by means of the positioning structure 212.

[0146] Specifically, the polygon can be a triangle, quadrilateral, pentagon, hexagon, octagon, etc. To increase the number of aerosol-generating articles 22 that the support 21 can accommodate, the polygon can have five or more sides. Alignment of at least one side of the polygon with the center of a receiving hole 211 along the radial direction of the support 21 means that the midpoint of at least one side of the polygon is aligned with the center of a receiving hole 211 along the radial direction of the support 21. At the beginning of heating each aerosol-generating consumable 20, a receiving hole 211 aligned with the center of one side of the polygon along the radial direction of the support 21 can be quickly positioned, and this receiving hole 211 serves as the starting point for the rotation of the support 21, thereby allowing the aerosol-generating articles 22 in the receiving hole 211 to begin changing positions and be heated one by one.

[0147] It is easy to understand that, in order for the support 21 to rotate via the positioning structure 212 to achieve the rotation of the positions of each aerosol generating article 22, each rotation of the positioning structure 212 and the support 21 should cause the receiving hole 211 to move along the circumference of the support 21 to the position of another adjacent receiving hole 211. In some embodiments, the relative positions of one or more aerosol generating articles 22 that are being heated or are to be heated with the pushing mechanism 12 and the heating mechanism 13 can always be consistent. With the repeated action of the pushing mechanism 12, the aerosol generating articles 22 can be rotated and heated one by one in the heating mechanism 13 at a fixed position.

[0148] In some embodiments, a plurality of receiving holes 211 are equidistantly spaced along the circumference of the support 21, and the cross-section of the positioning structure 212 is a regular polygon. Each side of the polygon can be aligned radially with the center of a receiving hole 211 along the support 21, further ensuring the positioning accuracy of the plurality of receiving holes 211 before and after the support 21 rotates, and after all aerosol production products are rotated for heating, the support 21 does not need to be reset to the initial position of heating and can be replaced as a whole.

[0149] Please see Figure 12 and Figure 17 In some implementations, the ratio of the number of receiving holes 211 to the number of sides of the polygon is an integer.

[0150] Thus, the ratio of the number of accommodating holes 211 to the number of sides of the polygon is an integer, which facilitates manufacturing and helps to simplify the design of the rotation mechanism of the positioning structure 212.

[0151] Specifically, taking a pentagonal polygon as an example, the number of holes 211 can be an integer multiple of 5, such as five, ten, fifteen, etc.

[0152] Please see Figure 12 and Figure 17 In some embodiments, the bracket 21 includes an outer peripheral surface 216, a first end surface 214 and a second end surface 215, the outer peripheral surface 216 connects the first end surface 214 and the second end surface 215, and the receiving hole 211 passes through the first end surface 214 and the second end surface 215.

[0153] Thus, the aerosol-generating article 22 is accommodated in the accommodating hole 211, which passes through the first end face 214 and the second end face 215, thereby facilitating the aerosol-generating article 22 to exit and enter the accommodating hole 211.

[0154] Specifically, multiple receiving holes 211 can be arranged circumferentially along the outer peripheral surface 216. The direction opposite to the first end face 214 and the second end face 215 of the bracket 21 can be vertical. The outer peripheral surface 216 of the bracket 21 refers to the surface that surrounds the bracket 21 laterally, without limiting the bracket 21 to a rotating structure, nor limiting the outer peripheral surface 216 of the bracket 21 to an arc surface or a curved surface.

[0155] The outer contours of both the first end face 214 and the second end face 215 are circular, and both are flat surfaces. The outer peripheral surface 216 is a curved surface surrounding the bracket 21. The opposite direction of the first end face 214 and the second end face 215 is also the axial direction of the bracket 21, and the circumferential direction of the outer peripheral surface 216 is also the circumferential direction of the bracket 21. The receiving hole 211 can penetrate the first end face 214 and the second end face 215 along the axial direction of the bracket 21. The receiving hole 211 is located radially between the geometric center of the bracket 21 and the outer peripheral surface 216.

[0156] Optionally, the positioning structure 212 is disposed on the second end face 215 of the bracket 21. The positioning structure 212 may be located at the geometric center of the second end face 215.

[0157] Please see Figure 12 In some embodiments, the bracket is formed with a notch 217 that penetrates the outer peripheral surface 216 and communicates with the receiving hole 211, and the notch 217 penetrates the first end face 214 and the second end face 215.

[0158] Thus, by passing through the outer peripheral surface 216 through the notch 217 and connecting with the receiving hole 211, the notch 217 provides space for other components, thereby making the structure more compact, improving space utilization, and facilitating the miniaturization of the aerosol generating device 10.

[0159] Specifically, the notch 217 can penetrate the first end face 214 and the second end face 215 along the axial direction of the bracket 21, and penetrate one side of the receiving hole 211 and the outer peripheral surface 216 along the radial direction of the bracket 21.

[0160] Please see Figure 12 In some embodiments, there are multiple notches 217, and the receiving holes 211 are provided in a one-to-one correspondence with the notches 217.

[0161] Please see Figure 12 In some embodiments, the receiving holes 211 are arranged at equal intervals along the circumferential direction of the outer peripheral surface 216.

[0162] Thus, the equidistant arrangement of the receiving holes 211 along the circumferential surface 216 facilitates the fabrication and shaping of the bracket 21, which is beneficial to the structural stability of the bracket 21. At the same time, it allows the aerosol generating products 22 to be arranged equidistantly along the circumferential surface 216, which is beneficial to the switching and precise stepping control of the aerosol generating products 22.

[0163] Specifically, when the support 21 is approximately cylindrical, the angle formed by the line connecting the center of each pair of adjacent receiving holes 211 along the circumference of the support 21 to the center of the support 21 is equal.

[0164] For example, the bracket 21 is provided with ten receiving holes 211 and correspondingly provided with ten notches 217, and the ten receiving holes 211 are arranged at equal intervals along the circumferential direction of the outer peripheral surface 216.

[0165] Please see Figure 2 The aerosol generating device 10 is provided with a receiving chamber 11, which is used to receive the support 21 or aerosol generating consumable 20 of any of the above embodiments.

[0166] Please see Figures 3-5 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.

[0167] 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.

[0168] 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.

[0169] Optionally, the drive shaft 152 is provided with a positioning member 153 fixedly connected to the positioning structure 212, and the positioning member 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 positioning member 153 is at least partially accommodated in the positioning hole 213. Furthermore, the shape and size of the positioning member 153 are matched with the positioning hole 213, so that the peripheral surface of the positioning member 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 positioning member 153 and the positioning hole 213.

[0170] In some embodiments, the cross-section of the positioning structure 212 is a polygon, and each side of the polygon is aligned with the center of a receiving hole 211 along the radial direction of the bracket 21. The ratio of the number of receiving holes 211 to the number of sides of the polygon is an integer. The cross-sectional shape and size of the positioning member 153 are the same as the cross-section of the positioning structure 212, thereby facilitating the assembly and positioning of the rotation drive mechanism 15 and the bracket 21.

[0171] Please see Figure 3 and Figure 4 In some embodiments, the aerosol generating apparatus 10 includes a pushing mechanism 12, which includes a pushing drive 121 and a pushing member 122. The pushing 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.

[0172] 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.

[0173] 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.

[0174] 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:

[0175] 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.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] 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.

[0180] 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.

[0181] The rotation drive mechanism 15 can drive the bracket 21 to rotate through the positioning structure 212, so that each aerosol generating product 22 to be heated can rotate to the interval between the first push part 1221 and the second push part 1222.

[0182] Please see Figure 3 and Figure 4 In some embodiments, the push rod 1223 includes a first connecting portion 1231, a second connecting portion 1232, and a connecting rod 1233. The first connecting portion 1231 connects the first pushing portion 1221 and one end of the connecting rod 1233, and the second connecting portion 1232 connects the second pushing portion 1222 and the other end of the connecting rod 1233. Both the first connecting portion 1231 and the second connecting portion 1232 are bent relative to the connecting rod 1233. Under the drive of the pusher drive member 121, the first connecting portion 1231 can move in the notch 217.

[0183] 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.

[0184] 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.

[0185] 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.

[0186] 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.

[0187] In some embodiments, the second propulsion unit 1222 is a hollow tube (not shown).

[0188] 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.

[0189] 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.

[0190] 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.

[0191] 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.

[0192] 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.

[0193] Please see Figures 12-14 The aerosol generating article 22 may include an aerosol generating matrix 221 and a coating layer 222, wherein the coating layer 222 covers at least a portion of the outer peripheral surface of the aerosol generating matrix 221. In some embodiments, the aerosol generating article 22 may only include the aerosol generating matrix 221. In other embodiments, the aerosol generating article 22 may further include a permeable plug, a filter section, a cooling section, etc., disposed at at least one end of the aerosol generating matrix 221.

[0194] In some embodiments, the thermal conductivity of the coating layer 222 is greater than that of the aerosol generating matrix 221, and the thermal conductivity of the coating layer 222 is between 50 W / (m*K) and 420 W / (m*K). For example, the thermal conductivity of the coating layer 222 is 50 W / (m*K), 100 W / (m*K), 150 W / (m*K), 300 W / (m*K), 350 W / (m*K), 420 W / (m*K), etc.

[0195] In the aerosol generating article 22 of the above embodiment, since the coating layer 222 covers at least part of the outer peripheral surface of the aerosol generating matrix 221, the contact area between the coating layer 222 and the aerosol generating matrix 221 is large. Furthermore, the thermal conductivity coefficient of the coating layer 222 is in the above large range. When it is suitable for a heating method that conducts heat from the outside to the inside, the coating layer 222 can quickly transfer heat to the aerosol generating matrix 221, so that the aerosol matrix generates aerosol after being heated, and the time for generating aerosol is short. In addition, controlling the thermal conductivity of the coating layer 222 to between 50W / (m*K) and 420W / (m*K) is beneficial for improving the inhalation experience. If the thermal conductivity is below 50W / (m*K), it will result in a long wait time during the first inhalation, and the aerosol odor of the first inhalation will be insufficient. If the thermal conductivity is above 420W / (m*K), it will be easy for an off-flavor, such as a burnt smell, to appear during the first inhalation.

[0196] Specifically, the coating layer 222 can cover part of the outer peripheral surface of the aerosol generating matrix 221, or it can completely cover the entire outer peripheral surface of the aerosol generating matrix 221. The coating layer 222 can be a metal foil, such as aluminum foil or copper foil, thereby giving the coating layer 222 a high thermal conductivity.

[0197] The specific shape of the aerosol generating matrix 221 is not limited; for example, the aerosol generating matrix 221 can be cylindrical. It should be noted that, in this embodiment of the invention, the length direction of the aerosol generating matrix 221 does not specifically refer to the direction of its longest external profile. For example, when the external profile of the aerosol generating matrix 221 is cylindrical, the length direction is the axial direction of the aerosol generating matrix 221. It should be noted that even when the axial length of the aerosol generating matrix 221 is less than its diameter, the length direction of the aerosol generating matrix 221 is still axial.

[0198] Please see Figure 13 and Figure 14 In some embodiments, the aerosol generating matrix 221 has a plurality of air guide holes 2212 penetrating two opposite end faces of the aerosol generating matrix 221, and the plurality of air guide holes 2212 are arranged at intervals along the circumference of the aerosol generating matrix 221.

[0199] In this way, the multiple air vents 2212 can smoothly guide the aerosols generated by the aerosol generating matrix 221 to the outside of the aerosol generating matrix 221, making the aerosol flow smoother.

[0200] Specifically, the air guide holes 2212 can be straight holes, thereby reducing the flow resistance of the aerosol and facilitating the outflow of the aerosol generation matrix 221. The number of air guide holes 2212 can be 2, 3, 4, etc.

[0201] It should be noted that all the air guide holes 2212 can be arranged radially along the aerosol generating matrix 221 to form one or more layers. In the same layer region, multiple air guide holes 2212 are arranged circumferentially at intervals. In different layer regions, the air guide holes 2212 of adjacent layers are radially spaced.

[0202] The aerosol generating matrix 221 contains micropores that are interconnected, forming micro-channels. At least some of these micro-channels are connected to the air guide holes 2212. Thus, the aerosols generated by the aerosol generating matrix 221 after heating can directly enter the air guide holes 2212 and be carried out by the airflow; alternatively, the airflow can directly enter the micro-channels and then enter the air guide holes 2212. It is understood that the interconnection between micropores can be partial or complete, or all micropores can be interconnected. It should be noted that micropores are pores in a microscopic sense and cannot be directly perceived by the naked eye.

[0203] Please see Figure 13 and Figure 14In some embodiments, the aerosol generating matrix 221 includes a plurality of medium layers 2213 and a plurality of connecting medium segments 2214. The plurality of medium layers 2213 are arranged at radial intervals along the aerosol generating matrix 221. The connecting medium segments 2214 connect two adjacent medium layers 2213. The two adjacent medium layers 2213 and the connecting medium segments 2214 together define an air guide hole 2212.

[0204] Thus, the dielectric layer 2213 and the connecting dielectric segment 2214 work together to facilitate the formation of the vent 2212. Specifically, the dielectric layer 2213 is cylindrical; for example, the dielectric layer 2213 can be cylindrical. Multiple dielectric layers 2213 are arranged in a nested configuration. The connecting dielectric segment 2214 is sheet-like or strip-like, located between two adjacent dielectric layers 2213, and connects the two adjacent dielectric layers 2213. Two adjacent connecting dielectric segments 2214 and two adjacent dielectric layers 2213 together form a vent 2212.

[0205] The medium layer 2213 and the connecting medium segment 2214 can be an integral structure, which is beneficial to improving the overall structural strength of the aerosol generating matrix 221, facilitating processing and molding, and reducing the probability of the aerosol generating matrix 221 deforming during heating, which could lead to obstruction of the air guide holes 2212. It is also beneficial to reduce the probability of the aerosol generating matrix 221 being damaged or broken during transportation, which could lead to failure. At the same time, it is beneficial to increase the solid structural density of the aerosol generating matrix 221. While ensuring the lifespan of the aerosol generating matrix 221 after a few suction cycles, it is beneficial to increase the total cross-sectional area of ​​all air guide holes 2212 perpendicular to the length direction, making the suction resistance and the flow rate of the air more suitable, thus improving the user experience.

[0206] The connecting medium segment 2214 can extend along one end face of the medium layer 2213 to the other end face, or it can be located between the two end faces of the medium layer 2213.

[0207] Please see Figure 14 In some embodiments, the thickness of the outermost dielectric layer 2213 is W1, where W1 satisfies: 0.1mm ≤ W1 ≤ 0.7mm. For example, W1 can be values ​​such as 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, and 0.7mm. Thus, when applied to a peripheral heating method, i.e., a heating method where heat is conducted from the outside in, since the outermost dielectric layer 2213 is heated first, with W1 within the above range, the outermost dielectric layer 2213 can concentrate heat within a limited volume of the dielectric during the first or first few heating cycles, minimizing heat transfer to the inner dielectric layers 2213. This allows the outermost dielectric to quickly reach the effective atomization temperature, accelerating the aerosol outflow rate during the first suction, increasing the initial aerosol volume, and ensuring the atomization of high-boiling-point active ingredients.

[0208] If W1 is less than 0.1 mm, the total volume of the outermost dielectric layer 2213 is small, which is not conducive to increasing the amount of aerosol and is also not conducive to processing and molding, making it prone to damage. If W1 is greater than 0.7 mm, the volume of the outermost dielectric layer 2213 is large, the heat capacity increases, the aerosol generation rate will slow down, which is not conducive to rapid smoke emission and reduces the user's experience. More importantly, only a reasonable combination of the thermal conductivity of the coating layer 222 and W1 can achieve a better effect of both rapid aerosol generation and no burnt smell.

[0209] Please see Figure 14 In some embodiments, the length of the connecting medium segment 2214 along the radial direction of the aerosol generating matrix 221 is L, where L satisfies 0.1 mm ≤ L ≤ 1 mm. For example, L can be values ​​such as 0.1 mm, 0.2 mm, 0.5 mm, 0.8 mm, and 1 mm. Thus, after the outermost medium layer 2213 begins to heat up, the connecting medium segment 2214 will not transfer excessive heat to the inner medium layer 2213, concentrating heat within a limited volume of medium in a short time. This minimizes heat transfer to the inner medium layer 2213, allowing the outermost medium to quickly heat up to the effective atomization temperature, accelerating the aerosol outflow rate during the first suction, increasing the initial aerosol volume, and ensuring the atomization of high-boiling-point active ingredients.

[0210] When L is less than 0.1 mm, heat is easily transferred to the inner dielectric layer 2213. When L is greater than 1 mm, heat is not easily transferred to the inner dielectric layer 2213 during the subsequent heating process of the aerosol generation matrix 221, which is not conducive to the generation of aerosols in the inner dielectric layer 2213.

[0211] In some embodiments, the total area of ​​the multiple connecting medium segments 2214 connected to the outer medium layer 2213 is S1, and the total area of ​​the inner circumferential surface of the outer medium layer 2213 is S2. S1 / S2 satisfies 5% ≤ S1 / S2 ≤ 60%. For example, S1 / S2 can be values ​​such as 5%, 10%, 20%, 30%, 40%, 50%, 60%, etc.

[0212] Thus, when S1 / S2 is within the above value range, when the outermost medium layer 2213 is heated for the first time or in the first few times, the heat of the outermost medium layer will not be excessively transferred inward, resulting in a decrease in the amount of aerosol and taste in the first puff. At the same time, it ensures that the outermost medium layer 2213 has sufficient contact area with the air guide hole 2212, allowing the aerosol to be fully and transported to the user with the airflow, increasing the amount of aerosol inhaled. If the contact area S1 is too small, it will affect the speed of heat transfer to the inner medium layer 2213, affecting the amount of smoke inhaled later, which is not conducive to the processing and shaping of the aerosol generation matrix 221.

[0213] Please see Figure 13 and Figure 14 In some embodiments, the innermost dielectric layer 2213 has a central hole 2215, which extends through both ends of the central layer along the length of the aerosol-generating article 22. On one hand, the central hole 2215 facilitates airflow, making it easier for aerosols to flow out of the aerosol-generating matrix 221 and be drawn in. On the other hand, the central hole 2215 can be used to insert a needle heater, enabling the aerosol-generating matrix 221 to achieve central heating, i.e., a heating method where heat conduction proceeds from the inside out.

[0214] Specifically, the central hole 2215 can be a hole of a round or square shape. The central axis of the central hole 2215 is also the central axis of the aerosol generating matrix 221.

[0215] In some embodiments, the diameter of the central hole 2215 is D, where D satisfies 0.5 mm ≤ D ≤ 2.8 mm. For example, D can be 0.5 mm, 0.9 mm, 1.1 mm, 1.2 mm, 1.5 mm, 2.8 mm, etc. Thus, when the diameter of the central hole 2215 is within the above range, it not only facilitates aerosol outflow but also makes the overall volume of the aerosol generating matrix 221 suitable, facilitating its use.

[0216] In some embodiments, multiple connecting medium segments 2214 are radially distributed. Alternatively, multiple connecting medium segments 2214 are arranged radially with the center of the aerosol generating matrix 221 as the center. This radial distribution of the multiple connecting medium segments 2214 improves the utilization rate of the internal space of the aerosol generating matrix 221, while allowing each air guide hole 2212 to be arranged in an orderly and independent manner. On the one hand, this facilitates the arrangement of more air guide holes 2212 within a limited space, thereby increasing the total area of ​​the inner wall of the air guide holes 2212; on the other hand, it helps to reduce bends within the air guide holes 2212, allowing airflow to flow smoothly along its length, reducing airflow obstruction, and improving the thermal utilization rate and airflow efficiency of the aerosol generating matrix 221; simultaneously, it improves the structural strength of the aerosol generating matrix 221.

[0217] like Figure 16 As shown, in some embodiments, there are two dielectric layers 2213. Alternatively, the dielectric layers 2213 are divided into an inner dielectric layer 2213 and an outer dielectric layer 2213. This simplifies the structure of the aerosol generation matrix 221, makes it easier to manufacture, and reduces the production cost of the aerosol generation matrix 221.

[0218] Of course, in some embodiments, the number of dielectric layers 2213 can be 3, 4, 5, etc. For example... Figure 13 and Figure 14In the example, there are 3 dielectric layers 2213.

[0219] In some embodiments, the density of the aerosol generating matrix 221 is between 800 mg / cm³ and 1400 mg / cm³. For example, the density of the aerosol generating matrix 221 is 800 mg / cm³, 900 mg / cm³, 1000 mg / cm³, 1200 mg / cm³, 1400 mg / cm³, etc. Thus, the aerosol generating matrix 221 has a certain strength, maintains a specific morphology, has suitable porosity, and allows the generated aerosols to easily overflow onto the surface of the aerosol generating matrix 221, increasing the aerosol quantity.

[0220] In some embodiments, the specific heat capacity of the aerosol generating matrix 221 is 1800 J / (kg*K)-2900 J / (kg*K). For example, the specific heat capacity of the aerosol generating matrix 221 is 1800 J / (kg*K), 2000 J / (kg*K), 2500 J / (kg*K), 2900 J / (kg*K), etc. Thus, the aerosol generating matrix 221 absorbs appropriate amounts of heat, enabling rapid aerosol generation without a burnt odor. Furthermore, it facilitates the temperature equilibrium between the aerosol generating matrix 221 and the aerosol during use, reducing the amount of aerosol released during the suction interval and improving the user experience.

[0221] In some embodiments, the thermal conductivity of the aerosol generating matrix 221 is 0.15 W / (m*K)–0.45 W / (m*K). For example, the thermal conductivity of the aerosol generating matrix 221 is 0.15 W / (m*K), 0.2 W / (m*K), 0.25 W / (m*K), 0.35 W / (m*K), 0.45 W / (m*K), etc. Thus, the thermal conductivity of the aerosol generating matrix 221 is reasonable, allowing it to generate an appropriate amount of aerosol and maintain consistency before and after suction.

[0222] Please see Figure 15 In some embodiments, the thickness of the coating layer 222 is W2, where W2 satisfies 0.01 mm ≤ W2 ≤ 0.3 mm. For example, W2 can be 0.01 mm, 0.05 mm, 0.1 mm, 0.2 mm, and 0.3 mm. Thus, the thickness of the coating layer 222 is suitable, allowing for rapid heat transfer to the aerosol generating matrix 221. If the thickness of the coating layer 222 is less than 0.01 mm, it is difficult to manufacture and easily damaged; if the thickness of the coating layer 222 is greater than 0.3 mm, the thickness is too large, wasting material and hindering the rapid heat transfer to the aerosol generating matrix 221.

[0223] Please see Figure 13 In some embodiments, the covering layer 222 is provided with a plurality of heat insulation holes 2221, which penetrate the covering layer 222 and correspond to the connection between the aerosol generating matrix 221 and the support section 223. The plurality of heat insulation holes 2221 are arranged at intervals along the circumference of the covering layer 222.

[0224] Thus, the multiple heat insulation holes 2221 can prevent excessive heat from the covering layer 222 from being conducted to the support section 223, reducing the probability of the support section 223 overheating and melting or producing odors. In one example, the heat insulation holes 2221 can be completely aligned with the aerosol generating matrix 221; or partially aligned with the aerosol generating matrix 221 and partially aligned with the support section 223.

[0225] In some embodiments, the coating layer 222 may include two distinct portions, with the thermal conductivity of the coating layer 222 covering the support section 223 being lower than that of the coating layer 222 covering the aerosol generating matrix 221. This results in less heat being conducted from the coating layer 222 to the support section 223, reducing the probability of the support section 223 overheating and melting or producing an unpleasant odor.

[0226] Specifically, the covering layer 222 can be made of multiple materials. For example, the covering layer 222 covering the support section 223 can be formed by stacking a paper layer and a metal layer, wherein the paper layer covers the support section 223 and the metal layer covers the outside of the paper layer.

[0227] Please see Figure 12 In some embodiments, this application provides an aerosol generation consumable 20, which includes a support and an aerosol generation article as described in any of the above embodiments, with the aerosol generation article housed in a receiving hole.

[0228] The aerosol generation consumable 20 in this embodiment is a disposable consumable used to load multiple aerosol generation products 22 into the aerosol generation device 10. The positioning structure 212 causes the support 21 to rotate, so that the aerosol generation products 22 are heated alternately inside the aerosol generation device 10, thereby increasing the number of continuously suction ports and reducing the replacement frequency.

[0229] Specifically, once all aerosol generation products 22 contained in the aerosol generation consumable 20 have been drawn out, the aerosol generation consumable 20 can be removed from the aerosol generation device 10 and replaced. Compared to replacing a single aerosol generation product 22, this not only reduces the replacement frequency but also increases the number of suction ports.

[0230] Please see Figure 12In some embodiments, the aerosol generating consumable 20 includes a support section 223 with a porous structure, the support section 223 being received in a receiving hole 211, and the support section 223 being configured to axially mate with the aerosol generating article 22.

[0231] Thus, the support section 223 can prevent the residue or liquid of the aerosol generation matrix 221 from falling downward after heating, reducing the interference of the residue of the aerosol generation matrix 221 on other components.

[0232] Specifically, the support segment 223 is connected to at least one end of the aerosol generating matrix 221, and the aerosol generating article 22 and the support segment 223 are axially connected and housed together in the receiving hole 211. The shape of the support segment 223 is approximately the same as the shape of the aerosol generating article 22; for example, when the aerosol generating article 22 is cylindrical, the support segment 223 is also cylindrical.

[0233] The support section 223 has a porous structure, meaning that airflow can pass through the support section 223 to enter the aerosol generating matrix 221, thereby carrying the aerosol out of the aerosol generating device 10. The porous structure can be a through-hole or a discrete pore structure with airflow communication.

[0234] Please see Figure 15 In some embodiments, the covering layer 222 covers the support section 223.

[0235] Thus, the coating layer 222 covers the support section 223, which makes the support section 223 and the aerosol generating matrix 221 form a whole, making it difficult for them to move relative to each other. In other words, the aerosol generating product 22 is a whole, which facilitates the use of the aerosol product.

[0236] In some embodiments, the support section 223 and the aerosol-generating article 22 are separate structures.

[0237] In this way, the support section 223 and the aerosol generating article 22 can be respectively installed into the receiving hole 211, which facilitates the replacement and installation of the support section 223 and improves the positioning accuracy of the aerosol generating article 22 in the receiving hole 211. At the same time, the usage cost of the aerosol generating consumable 20 can be reduced when the bracket 21 and the support section 223 are reused. In addition, since the installation of the support section 223 is more convenient, the manufacturing cost of the aerosol generating consumable 20 can be reduced.

[0238] Please see Figure 12 In some embodiments, the length of the support section 223 is less than half the length of the receiving hole 211, or the length of the support section 223 is less than half the length of the aerosol generating article 22.

[0239] Thus, the length of the support section 223 is less than half the length of the receiving hole 211 or the aerosol generating product 22, thereby ensuring that the capacity of the aerosol generating matrix 221 loaded on the support 21 is large enough, and the shorter length of the support section 223 further reduces the manufacturing difficulty.

[0240] For example, the aerosol generating article 22 has a length of 10 mm, the support section 223 has a length of 2 mm, the receiving hole 211 has a length greater than 12 mm, and the outer diameter of the aerosol generating article 22 and the support section 223 and the inner diameter of the receiving hole 211 are all 5.4 mm.

[0241] Please see Figure 5 In some embodiments, the support section 223 is detachably connected to the bracket 21 and is axially movable along the receiving hole 211.

[0242] Thus, the support section 223 can exit from the receiving hole 211 along with the aerosol generating product 22, or enter the receiving hole 211 from outside the receiving hole 211, so that during the process of the aerosol generating product 22 being removed from the support 21 for heating, the support section 223 can also support the aerosol generating product 22 and seal the heating residue or residual liquid.

[0243] In some embodiments, the suction resistance of the support section 223 is greater than that of the aerosol generating matrix 221. Thus, the support section 223 has a higher pore density than the aerosol generating matrix 221, preventing residue from the aerosol generating matrix 221 from falling off. Combined with the air guide hole 2212, the overall suction resistance of the aerosol generating article 22 can also be adjusted, improving the user experience.
