Description

Technical Field

[0001] This utility model relates to the field of aerosol generation technology, specifically to an aerosol generation device and aerosol generation system. Background Technology

[0002] The aerosol generation system includes an aerosol generation product and an aerosol generation device. The aerosol generation product stores an aerosol generation matrix. When the aerosol generation product is placed in the aerosol generation device, the aerosol generation device can convert the aerosol generation matrix into aerosols through heating or other means. The aerosols are then discharged from the aerosol generation system for users to inhale.

[0003] In related technologies, once the aerosol generating matrix in each aerosol generating product is depleted, the user needs to manually replace it with a new aerosol generating product, resulting in a poor user experience. Utility Model Content

[0004] In view of this, the present application aims to provide an aerosol generating apparatus and aerosol generating system capable of continuously providing aerosols.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] This application provides an aerosol generating apparatus, comprising:

[0007] Heating components, including heating elements, for heating aerosol-generated articles;

[0008] The cartridge mounting tube includes multiple receiving positions arranged in a ring. The receiving positions are used to place aerosol generating products. The cartridge mounting tube also has an installation space inside. The multiple receiving positions are arranged on the outer periphery of the installation space. The heating element is disposed in the installation space.

[0009] A drive assembly, in cooperation with the cartridge mounting tube drive, drives the receiving positions to rotate around the heating element, such that each of the plurality of receiving positions is at least partially facing the heating element.

[0010] In some embodiments, the cartridge mounting tube is cylindrical, the receiving position is a receiving cavity, and a plurality of receiving cavities are arranged circumferentially along the inner wall of the cartridge mounting tube. Each receiving cavity extends along the axial direction of the cartridge mounting tube, and an air inlet and an air outlet are respectively formed at opposite ends of the receiving cavity along its extension direction.

[0011] In some embodiments, the receiving cavity is opened on the side facing the installation space to form a heating port, and at least in the heating state, the heating port is arranged directly opposite the heating element.

[0012] In some embodiments, the receiving cavity includes a first sub-cavity and a second sub-cavity, both extending axially along the cartridge mounting tube and at least partially connected to each other, the second sub-cavity being used to place the aerosol generating product, and the second sub-cavity being closer to the heating element than the first sub-cavity.

[0013] In some embodiments, the first sub-cavity forms at least a portion of the air inlet at one end along the axial direction of the cartridge mounting tube, and at least a portion of the air outlet at the other end, and / or, the second sub-cavity forms at least a portion of the air inlet at one end along the axial direction of the cartridge mounting tube, and at least a portion of the air outlet at the other end.

[0014] In some embodiments, the aerosol generating device further includes a nozzle, an air inlet channel, and an air outlet channel. One end of the air outlet channel is connected to the nozzle, and the other end is connected to the air outlet. One end of the air inlet channel is connected to the external air of the aerosol generating device, and the other end is connected to the air inlet.

[0015] In some embodiments, the heating assembly further includes a heat reflector, with at least a portion of the heating element located between the heat reflector and the inner wall of the mounting space along the radial direction of the cartridge mounting tube, so that the heat reflector can reflect the heat radiation generated by the heating element.

[0016] In some embodiments, the drive assembly includes a drive base and a driver, the driver engaging with the drive base to drive the drive base to rotate, and the cartridge mounting tube being detachably connected to the drive base.

[0017] This application also provides an aerosol generation system, which includes an aerosol generation article and any of the aerosol generation devices described in the foregoing embodiments, wherein the aerosol generation article is disposed in the accommodating position.

[0018] In some embodiments, the aerosol-generated product is in the form of sheets, strips, or tubes;

[0019] And / or, the aerosol generating article has an air passage hole extending along the axial direction of the cartridge mounting cylinder.

[0020] The aerosol generating device in this embodiment drives the heating component and the cartridge mounting tube to rotate relative to each other, allowing the heating element to continuously change its relative position with each accommodating position. This increases the area or space that can be heated, and consequently, allows for the arrangement of more and larger aerosol generating products on the cartridge mounting tube. This increases the lifespan of the aerosol generating products within the aerosol generating device, thereby increasing the duration and frequency of aerosol inhalation and improving the user experience. The rotational motion also reduces the space required for the cartridge mounting tube to move within the aerosol generating device, making the device more compact and improving user convenience.

[0040] In the description of the embodiments of this application, for ease of explanation, as shown in the accompanying drawings, the direction of arrow X is the straight line direction in which the "extension direction of the rotation axis" is located.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0043] This application provides an aerosol generating device 10, see below. Figures 1 to 5 The drive component 13 can drive one of the cartridge mounting tube 12 and the heating component 11 to rotate around the other, so that a portion of the multiple aerosol generating products 20 located on the cartridge mounting tube 12 or different portions of one aerosol generating product 20 can be gradually heated by the heating component 11 to continuously generate aerosol, thereby increasing the number of times the generated aerosol can be inhaled by the user.

[0044] Specifically, see Figures 1 to 5 The aerosol generating device 10 includes a heating component 11, a cartridge mounting tube 12, and a drive component 13.

[0045] The heating assembly 11 includes a heating element 111, which is used to heat the aerosol-generated article 20.

[0046] The cartridge mounting tube 12 includes multiple receiving positions arranged in a ring. These positions are used to hold the aerosol generating product 20. The cartridge mounting tube 12 also has an installation space 12b inside, with the multiple receiving positions arranged around the periphery of the installation space 12b. The heating element 111 is disposed within the installation space 12b. It is understood that the ring arrangement of the multiple receiving positions can form an annular cavity, and the aerosol generating product 20, which matches the annular cavity, can be cylindrical or spiral-shaped.

[0047] The drive assembly 13 is driven to cooperate with the cartridge mounting tube 12 to drive the receiving positions to rotate around the heating element 111 so that at least a portion of each of the multiple receiving positions is directly facing the heating element 111.

[0048] The heat generated by the heating element 111 can be transferred to the aerosol generating product 20 through heat conduction, infrared radiation, etc., so that the aerosol generating matrix in the aerosol generating product 20 is heated and converted into aerosol.

[0049] It is understandable that during the rotation of the cartridge mounting tube 12 relative to the heating assembly 11, the relative positions of each receiving position and the heating element 111 can change.

[0050] It is understandable that the motion trajectory formed by each accommodating position during rotation revolves around the rotation axis 10a.

[0051] The axis of rotation 10a refers to the virtual straight line around which the cartridge mounting tube 12 rotates.

[0052] As the cartridge mounting tube 12 rotates, the position of each receiving position relative to the heating element 111 continuously changes. Each receiving position can rotate to a position where at least part of it is directly opposite the heating element 111.

[0053] The heating element 111 heats the aerosol generating product 20 radially from the inside to the outside along the rotation axis 10a. The heating element 111 can utilize the space inside the movement trajectory of the accommodating position, which is beneficial to improving the space utilization rate inside the aerosol generating device 10, making the structure of the aerosol generating device 10 more compact, and improving the portability of the aerosol generating device 10.

[0054] At least a portion of the receiving position is directly opposite the heating element 111, meaning that at least a portion of the receiving position is located in the region closest to the heating element 111 in the rotation trajectory of the receiving position, and it is located on one side of the heating element 111 in the radial direction along the rotation axis 10a.

[0055] The aerosol generating device 10 in this embodiment drives the heating component 11 and the cartridge mounting tube 12 to rotate relative to each other, so that the heating element 111 can continuously change its relative position with each accommodating position. This is beneficial to increasing the number and size of the accommodating positions, which in turn allows for the arrangement of more or larger aerosol generating products 20 on the cartridge mounting tube 12. This increases the number of times the aerosol generating products 20 can be used in the aerosol generating device 10, thereby increasing the duration and frequency of aerosol inhalation by the user and improving the user experience. The rotational movement also reduces the space required for the cartridge mounting tube 12 to move within the aerosol generating device 10, making the structure of the aerosol generating device 10 more compact and improving the convenience for the user.

[0056] This application also provides an aerosol generation system, see embodiments thereof. Figures 1 to 5 The aerosol generation system includes an aerosol generation article 20 and any one of the aerosol generation devices 10 in the embodiments of this application, with the aerosol generation article 20 disposed in the accommodating position.

[0057] This improves the heating efficiency of the heating element 111 on the aerosol generating product 20, which is beneficial to improving the efficiency of aerosol generation by the aerosol generating product 20 and enhancing the user experience.

[0058] The specific method of forming the accommodating space is not limited.

[0059] For example, see Figure 3 , Figures 5 to 8 The cartridge mounting tube 12 is cylindrical, with a receiving cavity 12a. Multiple receiving cavities 12a are spaced circumferentially along the inner wall of the cartridge mounting tube 12. Each receiving cavity 12a extends along the axial direction of the cartridge mounting tube 12. An air outlet 12d and an air inlet 12c are formed at opposite ends of the receiving cavity 12a along its extension direction, respectively.

[0060] The axial direction of the cartridge mounting tube 12 is the extension direction of the rotation axis 10a.

[0061] In this way, the inner wall of the receiving cavity 12a can be used to fix the aerosol generating product 20, reducing the risk of the aerosol generating device moving relative to the cartridge mounting tube 12 during carrying, transportation and other situations.

[0062] Understandably, with at least a portion of the single receiving cavity 12a facing the heating element 111, both the air inlet 12c and the air outlet 12d are connected to the outside of the aerosol generating device 10. Air from outside the aerosol generating device 10 enters the receiving cavity 12a through the air inlet 12c to mix with the aerosol generated by the aerosol generating article 20. The air then carries the aerosol out of the receiving cavity 12a through the air outlet 12d and flows out of the aerosol generating device 10 for the user to inhale.

[0063] The air outlet 12d and the air inlet 12c are located on one side of the two sides of the receiving cavity 12a along the extension direction of the rotation axis 10a. On the one hand, this helps to reduce the heating effect of the heat generated by the heating element 111 on the air outlet 12d and the air inlet 12c, and helps to keep the temperature of the airflow flowing out of the aerosol production device within a suitable range, thus improving the user experience. On the other hand, it helps the airflow to flow in a straight line in the receiving cavity 12a, reducing the resistance to the airflow, increasing the flow speed of the airflow, and improving the user experience during the suction process.

[0064] In some embodiments, see Figure 3 , Figure 5 , Figure 6 and Figure 7 The cavity 12a is opened on the side facing the installation space 12b to form a heating port 12e. At least in the heating state, the heating port 12e is arranged facing the heating element 111.

[0065] By setting the heating port 12e, the structure that obstructs the cigarette cartridge mounting tube 12 between the heating element 111 and the opposite aerosol generating product 20 is reduced or even eliminated during the heating state, which is beneficial to improving the heating efficiency of the heating component 11 on the aerosol generating product 20 and improving energy utilization efficiency.

[0066] The fact that the heating port 12e and the heating element 111 are arranged opposite each other means that the two are arranged radially opposite each other along the rotation axis 10a.

[0067] A cavity 12a can correspond to multiple heating ports 12e, or it can have only one heating port 12e.

[0068] In some embodiments, see Figures 6 to 8 The installation space 12b is cylindrical, and the rotation axis 10a passes through the center of the circular cross-section of the installation space 12b.

[0069] In some embodiments, see Figure 6 and Figure 7The heating component 11 and the cartridge mounting tube 12 are radially spaced along the rotation axis 10a, so as to reduce the probability of friction between the heating component 11 and the cartridge mounting tube 12 during relative rotation, thereby improving their service life and also helping to reduce the energy consumption of driving rotation.

[0070] Understandably, air is a poor conductor of heat.

[0071] In some embodiments, see Figure 5 The heating element 111 is located on the first side of the heating assembly 11 along the radial direction of the rotation axis 10a. In the working state, in the projection plane perpendicular to the extension direction of the rotation axis 10a, the minimum distance between the projection outline of the heating assembly 11 and the heating port 12e along the radial direction of the rotation axis 10a is the first distance, and the minimum distance between the second side of the heating assembly 11 along the radial direction of the rotation axis 10a and the projection outline of the mounting space 12b is the second distance. The first distance is less than the second distance. That is, L1 < L2.

[0072] In other words, along the radial direction of the rotation axis 10a, the heating component 11 is not located in the center of the installation space 12b, but is offset from the center of the installation space 12b and is closer to the cartridge mounting tube 12, so that in the working state, the heating element 111 is closer to the aerosol generating product 20 that needs to be heated.

[0073] Thus, in the working state, it is beneficial to reduce the gap between the heating component 11 and the cartridge mounting tube 12, thereby reducing the adverse effects of air in the gap between the two on the heat emitted by the heating element 111 to the aerosol generating product 20; it is also beneficial to improve the heating efficiency of the aerosol generating product 20 when there is a large difference between the volume of the part of the heating component 11 located in the mounting space 12b and the volume of the mounting space 12b itself.

[0074] It should be noted that the first side and the second side are only used to distinguish the opposite sides in the radial direction along the rotation axis 10a, and are not used to refer to a specific side.

[0075] In some embodiments, see Figure 3 , Figure 5 and Figure 6 It includes a first sub-cavity 12aa and a second sub-cavity 12ab. Both the first sub-cavity aa and the second sub-cavity ab extend along the axial direction of the cartridge mounting tube 12 and are at least partially connected to each other. The second sub-cavity ab is used to place the aerosol generating product 20. The second sub-cavity ab is closer to the heating element 111 than the first sub-cavity aa.

[0076] The second sub-cavity ab is closer to the heating element 111, which helps to reduce the distance between the heating element 111 and the aerosol-generating product 20 in the second sub-cavity 12bb, thereby improving the heating efficiency of the aerosol-generating product.

[0077] In some embodiments, see Figure 6 The second sub-cavity 12aa is open on one side along the extension direction of the rotation axis 10a, and the aerosol generating article 20 can enter and exit the first sub-cavity 12aa through this open position.

[0078] This helps to reduce the obstruction of the heating component 11 during the replacement operation of the aerosol-generated product 20 in the first sub-cavity 12aa.

[0079] In some embodiments, see Figure 6 The first sub-cavity aa forms at least a partial air inlet at one end along the axial direction of the cartridge mounting tube 12, and at least a partial air outlet at the other end.

[0080] In other words, the airflow enters the first sub-cavity 12aa from the air inlet 12c and then exits the first sub-cavity 12aa through the air outlet 12d. During the flow of the airflow in the first sub-cavity 12aa, since the first sub-cavity 12aa is connected to the second sub-cavity 12ab, the surface of the aerosol generating product 20 on the side away from the heating element 111 can come into contact with the airflow, so that the aerosol generated by the aerosol generating product 20 can be carried out by the airflow after entering the first sub-cavity 12aa.

[0081] This helps to reduce the adverse effects on the user's inhalation experience caused by the airflow being directly heated by the heating element 111.

[0082] In some embodiments, see Figure 6 The second sub-cavity 12ab forms at least a partial air inlet 12c at one end along the axial direction of the cartridge mounting tube 12, and at least a partial air outlet 12d at the other end.

[0083] The airflow enters the second sub-cavity 12ab from the air inlet 12c, passes through the aerosol generating product 20 and mixes with the aerosol, and is then discharged from the air outlet 12d, thereby enabling the airflow to carry the aerosol for the user to inhale; at the same time, it is convenient to directly use the air outlet 12d and the air inlet 12c to pick up and put in the aerosol generating product 20, thereby simplifying the cartridge installation tube 12.

[0084] In some embodiments, see Figure 7 and Figure 8 The aerosol generating article 20 is provided with a through air channel hole 20a in order to increase the surface area of ​​the aerosol generating article 20 and increase the contact area between the aerosol and the airflow.

[0085] The aerosol generating product 20 may have only one air passage 20a or multiple air passages 20a.

[0086] In some embodiments, when the aerosol generating article 20 is inserted into the receiving cavity 12a, in the projection plane perpendicular to the extension direction of the rotation axis 10a, the projection of one end of the air passage hole 20a is located within the projection range of the air inlet 12c, and the projection of the other end of the air passage hole 20a is located within the projection range of the air outlet 12d.

[0087] In this way, after the airflow enters the receiving cavity 12a through the air inlet 12c, it can directly enter the air passage 20a, which is beneficial to improving the mixing efficiency of airflow and aerosol.

[0088] It is understandable that the air inlet 12c and the air outlet 12d may be connected to only one air passage 20a, or they may be connected to multiple air passages 20a.

[0089] In some embodiments, the aerosol generating article 20 has an air passage hole 20a extending in the axial direction along the cartridge mounting tube 12.

[0090] In some embodiments, see Figure 6 and Figure 7 Multiple accommodating cavities 12a are isolated from each other and arranged around the rotation axis 10a.

[0091] Thus, through the relative rotation between the heating component 11 and the cartridge mounting tube 12, the aerosol generating products 20 in the multiple receiving cavities 12a can be successively heated by the heating component 11 during operation. Since the receiving cavities 12a are isolated from each other, the heat and aerosol in the heated receiving cavities 12a are unlikely to affect the aerosol generating products 20 in the unheated receiving cavities 12a, thereby improving the user experience.

[0092] It is understandable that in the multiple surrounding accommodating cavities 12a, the circumferential spacing between each two adjacent accommodating cavities 12a along the rotation axis 10a is the same, so that the heating assembly 11 and the cartridge mounting tube 12 can be in working condition each time they rotate relative to each other at a fixed angle, which facilitates control.

[0093] In other embodiments, see Figure 8 Each of the receiving cavities 12a is connected to each other along the circumference of the cigarette cartridge mounting tube 12.

[0094] This allows for a larger volume ratio of the containing cavity 12a to the entire cartridge mounting tube 12, which in turn facilitates the arrangement of a larger volume of aerosol products, thereby extending the number of times and duration of use for the user and improving the user experience.

[0095] In some embodiments, the cavity 12a contains a plurality of aerosol generating articles 20, which abut against each other circumferentially along the axis of rotation 10a to constrain the position of the aerosol generating articles 20 within the cavity 12a.

[0096] In other embodiments, see Figure 8 Each of the multiple receiving cavities 12a contains only one aerosol generating product 20, which is an annular cylindrical shape. This allows the aerosol generating product 20 to be removed and placed from the receiving cavity 12a in one go.

[0097] In some embodiments, see Figure 2 The aerosol generating device 10 also includes a nozzle 16, an air inlet channel 15b, and an air outlet channel. One end of the air outlet channel is connected to the nozzle 16, and the other end is connected to the air outlet 12d. One end of the air inlet channel 15b is connected to the external air of the aerosol generating device 10, and the other end is connected to the air inlet 12c.

[0098] It is understandable that the nozzle 16 is provided with an exhaust port 16b, one end of which is connected to the air outlet channel and the other end is connected to the outside of the aerosol generating device.

[0099] In some embodiments, see Figure 2 and Figure 3 The aerosol generating device 10 also includes a gas collecting hood 14, which has a gas collecting chamber 14a and a gas outlet 14b. The gas collecting hood 14 is located on one side of the cartridge mounting cylinder 12 along the extension direction of the rotation axis 10a. The gas collecting chamber 14a extends along the extension direction of the rotation axis 10a. The cross section of the gas collecting chamber 14a perpendicular to the rotation axis 10a gradually decreases in the direction away from the cartridge mounting cylinder 12. Both sides of the gas collecting chamber 14a are open along the extension direction of the rotation axis 10a. One open position is connected to the gas outlet 12d, and the other open position is connected to the gas outlet 14b. The gas outlet 14b extends along the extension direction of the rotation axis 10a and is connected to the outside of the aerosol generating device 10.

[0100] In this way, after the airflow and aerosol enter the gas collecting chamber 14a, the convergence effect of the inner wall of the gas collecting chamber 14a helps to increase the airflow velocity.

[0101] The air collecting chamber 14a and the air outlet 14b form an air outlet channel.

[0102] In some embodiments where there are multiple air outlets 12d, in a projection plane perpendicular to the rotation axis 10a, the projections of all air outlets 12d are located within the projection range of the open position where the air collection chamber 14a communicates with the air outlets 12d, which helps to improve the efficiency of airflow.

[0103] In some embodiments, see Figures 7 to 10 The heating assembly 11 also includes a heat reflector 112. Along the radial direction of the cartridge mounting tube 12, at least a portion of the heating element 111 is located between the heat reflector 112 and the inner wall of the mounting space 12b, so that the heat reflector 112 can reflect the heat radiation generated by the heating element 111.

[0104] The heat reflector 112 can reflect the heat radiation emitted by the heating element 111 in the radial direction away from the receiving cavity 12a along the rotation axis 10a, so that at least part of the heat radiation can change its radiation direction and move toward the receiving cavity 12a and reach the surface of the aerosol generating article 20.

[0105] This allows more of the heat generated by the heating component 11 to be absorbed by the aerosol generating product 20, thereby improving the heating efficiency of the aerosol generating product 20.

[0106] In some embodiments, see Figures 7 to 10 The heat reflector 112 surrounds the heating space 112a, at least a portion of the heating element 111 is located in the heating space 112a, and the heat reflector 112 forms a light-transmitting area 112b on one radial side along the rotation axis 10a. Heat radiation in the heating space 112a can pass through the light-transmitting area 112b to heat the aerosol-generated article 20 in the working state.

[0107] Thus, by heating the space 112a, on the one hand, it is beneficial to reflect the heat radiation emitted by the heating element 111 in more directions, further improving the heating efficiency of the aerosol generating product 20; on the other hand, the heat reflector 112 can play a certain protective role for the heating element 111, reducing the risk of foreign objects adhering to the heating element 111 and causing problems such as odor or damage to the heating element 111.

[0108] It is understood that in embodiments where the first distance is less than the second distance, the light-transmitting area 112b is located on the first side of the heating assembly 11 in the radial direction along the rotation axis 10a, in order to improve the heating efficiency of the aerosol-generating article 20.

[0109] In some embodiments, see Figure 10 The heating element 111 is completely located within the heating space 112a, so as to further improve the heat reflection efficiency of the heat reflector 112 and the protection effect on the heating element 111.

[0110] In some embodiments where the heating element 111 is entirely located within the heating space 112a, see [reference]. Figure 10 Along the radial direction of the rotation axis 10a, the distance between the heating element 111 and the light-transmitting area 112b is less than the distance between the heating part and the inner wall of the heating space 112a on the other side. That is, L3 < L4.

[0111] This allows the heat radiation emitted from the light-transmitting area 112b to reach the aerosol-generating product 20 over a shorter distance, which is beneficial for improving the heating efficiency of the aerosol-generating product 20.

[0112] The specific method by which the heat reflector 112 reflects heat is not limited.

[0113] For example, see Figure 7 and Figure 8 The heat reflector 112 is a plate-shaped structure made of metal material. It is bent to form a heating space 112a. The heating space 112a is open on one side of the radial direction along the rotation axis 10a to form a light-transmitting area 112b. The surface of the heat reflector 112 facing the heat-generating body 111 is smooth to reflect heat radiation.

[0114] The specific type of metal material used for the heat reflector 112 is not limited, such as stainless steel, to improve the high temperature resistance of the heat reflector 112 itself.

[0115] For example, see Figure 9 and Figure 10 The heat reflector 112 includes a light-transmitting cylinder 1121, a heat-reflecting film 1122, and at least two heat-insulating flanges 1123. The light-transmitting cylinder 1121 has a mounting cavity 1121a extending along the rotation axis 10a. The two heat-insulating flanges 1123 are respectively covered on one open side of the mounting cavity 1121a to form a heating space 112a together with the light-transmitting cylinder. The light-transmitting cylinder 1121 includes a reflective area 112c and a light-transmitting area 112b. The heat-reflecting film 1122 covers the outer surface of the reflective area 112c on the side away from the mounting cavity 1121a.

[0116] The through-tube and the heat insulation flange 1123 help to isolate the heating space 112a from the outside space, thereby reducing the probability of damage to other components in the heat transfer aerosol production device and further reducing the chance of foreign objects entering the heating space 112a.

[0117] The specific material used for the heat insulation flange 1123 can be ceramic, so as to achieve good heat insulation.

[0118] It is understandable that the light-transmitting tube 1121 itself is made of light-transmitting material, wherein the reflective area 112c is covered with a heat-reflective film 1122, so that the heat radiation returns to the heating space 112a under the reflection of the heat-reflective film 1122. Thus, through one or more reflections, the heat radiation can be emitted from the light-transmitting area 112b.

[0119] The material of the light-transmitting tube 1121 can be quartz. Quartz has high light transmittance, which helps to reduce the heat damage of the light-transmitting tube 1121 itself and improves the heating efficiency of the aerosol generating product 20.

[0120] The heating element 111 can be a high-temperature resistant heating wire made of nickel-chromium or nickel-chromium-aluminum material.

[0121] In some embodiments, see Figure 2 and Figure 3 The drive assembly 13 includes a drive base 131 and a driver 132. The driver 132 drives the drive base 131 to rotate. The cartridge mounting tube 12 is detachably connected to the drive base 131.

[0122] The cartridge mounting tube 12 is detachably connected to the drive base 131 so that after the cartridge mounting tube 12 is separated from the drive base 131, the cartridge mounting tube 12 can be taken out separately to replace the aerosol generating product 20 on the cartridge mounting tube 12, and then the cartridge mounting tube 12 can be reinstalled onto the drive base 131, thereby achieving the purpose of replenishing new aerosol generating products 20.

[0123] During the rotation of the drive seat 131, the heating component 11 is located inside the movement trajectory of the drive seat 131.

[0124] In this way, the heating component 11 can utilize the space inside the movement trajectory of the drive seat 131, which is beneficial to improving the space utilization rate inside the aerosol generating device 10, making the structure of the aerosol generating device 10 more compact, and improving the portability of the aerosol generating device 10.

[0125] In some embodiments, the drive base 131 is provided with a mounting hole 131a extending along the extension direction of the rotation axis 10a, and at least a portion of the heating assembly 11 passes through the mounting hole 131a.

[0126] In some embodiments, see Figure 2 and Figure 3 The driver 132 includes a drive motor 1321 and a drive gear 1322. The inner wall of the mounting hole 131a is provided with a driven tooth 1311 circumferentially arranged along the rotation axis 10a. The drive end of the drive motor 1321 is connected to the drive gear 1322, and the drive gear 1322 meshes with the driven tooth 1311.

[0127] Thus, the rotation of the drive seat 131 is achieved through gear transmission, and at least part of the drive gear 1322 is located in the mounting hole 131a, which helps to make the structure of the aerosol generating device 10 more compact.

[0128] In some embodiments, see Figure 12One of the drive seat 131 and the cartridge mounting tube 12 is fixed in a groove, and the other is provided with a fixed protrusion 1312. The fixed protrusion 1312 protrudes along the extension direction of the rotation axis 10a. One side of the fixed groove along the extension direction of the rotation axis 10a is open so that the fixed protrusion 1312 can be inserted into the fixed groove, so that the fixed protrusion 1312 and the inner wall of the fixed groove are in a stop engagement perpendicular to the extension direction of the rotation axis 10a.

[0129] In some embodiments, see Figure 2 The aerosol generating device 10 includes a mounting shell assembly 15 and a mouthpiece 16. The mounting shell assembly 15 and the mouthpiece 16 are detachably connected and together enclose a receiving space 10b. At least a portion of the cartridge mounting tube 12, the heating assembly 11, and at least a portion of the driving assembly 13 are all located within the receiving space 10b.

[0130] The space 10b serves to protect the space and provide a location for installation.

[0131] After the mounting shell assembly 15 is separated from the mouthpiece 16, the aerosol generating product 20 can be replaced in the cartridge mounting tube 12.

[0132] In some embodiments, see Figure 3 The mounting shell assembly 15 is provided with a first receiving sub-cavity 15a. The first receiving sub-cavity 15a forms a pick-and-place port on one side along the extension direction of the rotation axis 10a. When the mounting shell assembly 15 is separated from the mouthpiece 16, the pick-and-place port is open to communicate with the outside. The cartridge mounting tube 12 is detachably connected to the drive assembly 13. In the projection plane perpendicular to the rotation axis 10a, the projection of the cartridge mounting tube 12 is located within the projection range of the pick-and-place port.

[0133] In this way, the cartridge holder 12 can be removed from the insertion port while the housing assembly 15 is separated from the mouthpiece 16, so as to replace the aerosol generating product 20.

[0134] In some embodiments with a drive base 131, a positioning groove is provided on the side of the first receiving cavity 15a opposite to the pick-and-place port along the extension direction of the rotation axis 10a. The positioning groove is open on the side facing the pick-and-place port, and a part of the heating component 11 is located in the insertion positioning groove so as to realize the installation and positioning of the heating component 11.

[0135] In some embodiments where an air inlet 12c is provided, see [reference]. Figure 3 The mounting housing assembly 15 is provided with an air intake channel 15b, which connects the outside of the aerosol generating device 10 with the first receiving sub-cavity 15a. A portion of the air intake channel 15b extends along the extension direction of the rotation axis 10a to communicate with the air intake 12c.

[0136] In some embodiments where a drive base 131 is provided, see [reference]. Figure 3 The drive seat 131 is located in the first receiving sub-cavity 15a. The drive seat 131 is provided with a transfer air hole 131b extending along the extension direction of the rotation axis 10a. The transfer air hole 131b connects the air inlet 12c and the air inlet channel 15b. In this way, by reducing the empty space in the first receiving sub-cavity 15a, the air in the receiving space 10b is reduced, which is conducive to the user forming negative pressure in the receiving space 10b more quickly during the suction process.

[0137] In some embodiments where a gas collection hood 14 is provided, see [reference]. Figure 3 The mouthpiece 16 is provided with a second receiving sub-cavity 16a and an exhaust port 16b. The exhaust port 16b extends along the extension direction of the rotation axis 10a and communicates with the outside of the aerosol generating device 10. The second receiving sub-cavity 16a is located on the side of the exhaust port 16b that is close to the first housing assembly along the extension direction of the rotation axis 10a. The side of the second receiving sub-cavity 16a that is close to the first housing assembly is open to communicate with the first receiving sub-cavity 15a. The gas collecting hood 14 is located inside the first receiving sub-cavity 15a. The gas collecting cavity 14a communicates with the first receiving sub-cavity 15a, and the exhaust port 14b communicates with the exhaust port 16b, so that the gas collecting hood 14 can be separated from the second housing assembly so that the installation and removal of the cartridge 12 are not obstructed.

[0138] In some embodiments, see Figure 7 The aerosol generating product 20 is sheet-shaped, which facilitates increasing the area of ​​the aerosol generating product 20 that is heated by the heat radiation of the heating element 111.

[0139] In some embodiments, see Figure 5 and Figure 6 The aerosol generating product 20 is in strip shape, making it convenient for users to pick up and put away the aerosol generating product 20.

[0140] In some embodiments, see Figure 8 The aerosol generating product 20 is cylindrical, allowing for one-time loading and unloading of the aerosol generating product 20 from the cartridge mounting tube 12.
