[0014] The switching mechanism includes an air intake ring corresponding to the annular groove. The air intake ring has a connecting port for connecting to the external environment. The air intake ring can rotate along the extension direction of the annular groove so that the connecting port connects to one of the air intake ports and blocks the other air intake ports.

[0015] In some embodiments, the aerosol generating device includes a drive mechanism disposed within the mounting cavity and electrically connected to the power supply assembly. The heating element corresponding to each of the receiving cavities is connected to the drive mechanism. The drive mechanism is used to drive the heating element to move axially along the receiving cavity to heat the aerosol generating product segment by segment.

[0055] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0056] This application provides an aerosol generating device. Please refer to [link to relevant documentation]. Figures 1 to 17 It includes a housing 10, multiple independently configured heating components 11, a switching mechanism 12, and a power supply component 13.

[0057] The housing 10 has a mounting cavity 10a, and the outer surface of the housing 10 is provided with a plurality of air inlets 10b.

[0058] Multiple independently configured heating components 11 are disposed within the mounting cavity 10a. Each heating component 11 has a receiving cavity 11a, which is open on one side along its own axial direction for at least a portion of the aerosol generating article 20 to be inserted. Each receiving cavity 11a is connected to an air inlet 10b. Each heating component 11 includes at least one heating element 111 for heating the aerosol generating article 20.

[0059] The switching mechanism 12 is disposed in the housing 10 and is movable relative to the housing 10 to open one of the air inlets 10b and simultaneously close the other air inlets 10b.

[0060] The power supply assembly 13 is disposed inside the housing 10, and each heating element 111 is connected to the power supply assembly 13.

[0061] Here, the housing 10 can serve as the exterior component of the aerosol generating device, providing protection for the internal heating components 11, power supply components 13, etc., and reducing the probability of the heating components 11 and power supply components 13 being damaged by impact.

[0062] The outer surface of the housing 10 is provided with multiple air inlets 10b, which can connect to the external environment and / or the mounting cavity 10a. Thus, during suction, under the action of negative pressure, air from the external environment can enter the receiving cavity 11a, while the aerosol generated after the heated aerosol is used to produce the product leaves the housing 10 and is used by the user.

[0063] The number of air inlets 10b can be two, three or more.

[0064] Here, multiple independently configured heating components 11 means that multiple heating components 11 can work independently. When one heating component 11 is working, the other heating components 11 may or may not work.

[0065] Multiple heating components 11 have multiple receiving cavities 11a, each receiving cavity 11a being able to accommodate at least one aerosol generating article 20, which may be partially inserted into the receiving cavity 11a or fully inserted into the receiving cavity 11a.

[0066] Each receiving cavity 11a corresponds to one air inlet 10b, meaning that the air intake channel of each receiving cavity 11a is independent, and each receiving cavity 11a intakes air independently. When its corresponding air inlet 10b is closed, the receiving cavity 11a does not intake air. The power supply assembly 13 can conduct electrical connection with the heating element 111 corresponding to the open air inlet 10b and disconnect electrical connection with the heating element 111 corresponding to the closed air inlet 10b.

[0067] Each heating component 11 includes at least one heating element 111, meaning that in each receiving cavity 11a, there can be only one heating element 111 heating the aerosol generating article 20, or multiple heating elements 111 heating the aerosol generating article 20; there is no limitation here. Multiple heating elements 111 heating the aerosol generating article 20 can meet personalized smoke volume requirements, while a single heating element 111 heating the aerosol generating article 20 can reduce usage costs, increase heating consistency, and simplify the structure.

[0068] The heating element 111 can heat the aerosol generating article 20 in any way, including resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, etc., and is not limited here. In this embodiment, the aerosol generating article 20 is described as being drawn in by a heating-non-combustible method.

[0069] For example, the heating element 111 heats the aerosol generating article 20 that enters the receiving cavity 11a using a peripheral heating method. The peripheral heating method means that the heating element 111 is located on the periphery of the aerosol generating article 20 to bake and heat the aerosol generating article 20 from the outside to the inside.

[0070] The outer contour of the aerosol generating article 20 can be cylindrical, cuboid, sheet-like, etc., and there is no limitation. The aerosol generating article 20 includes at least an aerosol generating matrix section, and the aerosol generating matrix section may be wrapped with packaging materials such as aluminum foil or cigarette paper to prevent the generated aerosol from leaking out.

[0071] The aerosol-generating matrix segment is made from tobacco or herbaceous media.

[0072] The aerosol-generating product 20 can be a one-piece structure, for example, formed by injection molding, compression molding, or extrusion. Extrusion molding refers to a processing method in which a mixture of raw materials is added to an extruder, and the material is pushed forward by the screw or piston through the barrel and screw head to continuously produce products or semi-finished products of various cross-sections. For example, the aerosol-generating product 20 is a one-piece extruded structure. Thus, the aerosol-generating product 20 remains a one-piece medium after heating and suction or after heating stops, making it less prone to disintegration and falling off. This reduces the problems of sheet-like, filamentous, or granular aerosol-generating products in related technologies, such as sheet detachment, filamentous component fall-off, and granular component fall-off, resulting in high heating reliability. The aerosol-generating product 20 can also have a straight air passage extending along its length, which facilitates aerosol release; in addition, the sidewall of the aerosol-generating product 20 can be provided with multiple air inlets to facilitate the entry and removal of different types of air and the carry-out of aerosols.

[0073] The switching mechanism 12 is movable relative to the housing 10 to open one of the air inlets 10b and close the others. This means that the switching mechanism 12 can, through its movement relative to the housing 10, open the air intake of only one of the receiving cavities 11a and close the air intake of the others. In this case, only one of the air inlets 10b can guide air from the external environment to its corresponding receiving cavity 11a.

[0074] The movement of the switching mechanism 12 relative to the housing 10 can be sliding, rotating, or a combination of both, and there are no restrictions here.

[0075] For example, when the switching mechanism 12 opens one of the air inlets 10b and closes the others, the user generates negative pressure through suction. The opened air inlet 10b connects the external environment to the receiving cavity 11a. Under negative pressure, air from the external environment can enter the receiving cavity 11a through the air inlet 10b. Additionally, the power supply component 13 establishes an electrical connection with the heating element 111 corresponding to the opened air inlet 10b, providing power to the heating element 111. This allows the heating element 111 to heat the aerosol-generating product 20, causing air from the external environment to carry the aerosol away from the receiving cavity 11a under negative pressure, which is then inhaled by the user. The heating element 111 corresponding to the closed air inlet 10b is disconnected from the power supply component 13 and will not perform heating, increasing operational safety. Thus, after suctioning one aerosol-generating product 20, the switching mechanism 12 can be used to switch to suctioning the next aerosol-generating product 20.

[0076] For example, the aerosol generating device may be equipped with a detection unit to detect the condition at each air inlet 10b to determine which air inlet 10b is open and can allow air to enter, thereby generating a corresponding detection signal and transmitting it to the power supply component 13. The power supply component 13 can then conduct the conductive connection with the heating element 111 corresponding to the open air inlet 10b and disconnect the conductive connection with the heating element 111 corresponding to the closed air inlet 10b based on this detection signal.

[0077] It should be noted that the power supply component 13 is located inside the housing 10. It can be located inside the mounting cavity 10a or in other spaces inside the housing 10 that are not connected to the mounting cavity 10a, as long as it can provide power to the heating element 111. There are no restrictions here.

[0078] The aerosol generating device provided in this application embodiment can accommodate multiple aerosol generating products 20 for user suction without requiring repeated manual replacement of the aerosol generating products 20, thus satisfying multiple suctions and large-volume suctions, and offering high ease of use. Simultaneously, multiple heating components 11 are independently configured, meaning each aerosol generating product 20 is independently configured, and each receiving cavity 11a corresponds to an air inlet 10b. This ensures that heating does not interfere with each other. When heating one aerosol generating product 20, the corresponding air inlet 10b is opened by the switching mechanism 12, while the other air inlets 10b are closed, ensuring appropriate suction resistance and preventing external air from contaminating the other aerosol generating products 20, increasing the storage reliability of the aerosol generating products 20. Furthermore, each aerosol generating product 20 can be heated in its corresponding receiving cavity 11a without affecting other aerosol generating products 20, ensuring that fresh aerosol generating products 20 are suctioned each time, resulting in a superior user experience. The term "large number of puffs" refers to a large number of puffs, such as more than fifty, more than one hundred, or even around five hundred.

[0079] This application provides an aerosol generation system 100, including an aerosol generation article 20 and an aerosol generation device according to any embodiment of this application, wherein the aerosol generation article 20 is disposed in a receiving cavity 11a.

[0080] Understandably, the number of suction ports for a single aerosol generating product 20 can be set and calculated, for example, by counting with a microphone, counting by thermocouple temperature changes, or counting with an airflow sensor. In this way, the number of aerosol generating products 20 placed in the aerosol generating device can be adjusted, and the total number of suction ports can be adjusted to meet the port number requirements.

[0081] For example, please refer to Figure 6The outer contour of the aerosol generating article 20 is generally cylindrical. The outer diameter of the cylinder can be from 3 mm to 8 mm, for example, 3 mm, 3.3 mm, 4 mm, 4.5 mm, 5 mm, 5.4 mm, 6 mm, 6.6 mm, 7 mm, 7.2 mm, 8 mm, etc. Thus, the size of the aerosol generating article 20 is suitable to match different heating methods and different heating elements 111. The length of a single aerosol generating article 20 can be 0.3 mm or more, for example, 20 mm, 30 mm, 50 mm, or it can be composed of multiple stacked aerosol generating matrix segments, for example, a single aerosol generating matrix segment is 0.2 mm or more.

[0082] The specific structure of the aerosol-generated product 20 is not limited.

[0083] In some embodiments, please refer to Figure 6 and Figure 8 Along the axial direction of the aerosol generating article 20, the aerosol generating article 20 includes a stop 201, a medium section 202 and a filter section 203. The medium section 202 is used to generate aerosols and is disposed between the filter section 203 and the stop 201. The stop 201 is disposed upstream of the medium section 202 along the airflow direction.

[0084] Here, the medium section 202 is used to generate aerosols, that is, at least a portion of the medium section 202 is composed of an aerosol generating matrix, so that the medium section 202 can generate aerosols for user use, and the medium section 202 is the effective suction portion of the aerosol generating article 20.

[0085] The medium section 202 can be a one-piece extrusion molding structure.

[0086] During suction, air from the external environment enters through the air inlet 10b, passes through the stop 201, and then enters the medium section 202. The stop 201 can adjust the suction resistance, reduce the probability of condensate flowing out of the aerosol to form product 20 after aerosol condensation, and also reduce the probability of differences in the composition of the aerosol caused by the change in heating temperature due to the direct entry of air from the external environment into the medium section 202.

[0087] The stop 201 can cooperate with the stop of the medium section 202 to stabilize the position of the medium section 202 and increase the reliability of transportation and installation of the aerosol generated product 20.

[0088] The filter section 203 can filter impurities or harmful substances carried in the aerosol and adsorb the condensate or large droplets formed by the aerosol condensation, keeping the aerosol dry and improving the user experience. On the other hand, it can also adjust the suction resistance, making the aerosol content generated per unit time more reasonable.

[0089] For example, filter section 203 may be a solid cellulose acetate structure.

[0090] In some embodiments, please refer to Figure 4 , Figure 8 and Figure 9 The medium section 202 has at least one air passage 202a, which passes through at least one end of the medium section 202 near the filter section 203 along the axial direction.

[0091] In this way, the aerosol generated by the heating of the medium section 202 can be directly released from the air passage 202a and leave the containment cavity 11a. The aerosol has sufficient release space, which improves the aerosol extraction rate.

[0092] It should be noted that the air passage 202a penetrates at least one end of the medium section 202 near the filter section 203 along the axial direction, which includes various cases.

[0093] The first type: the airway hole 202a only passes through the end of the medium section 202 near the filter section 203. That is to say, the end of the airway hole 202a near the filter section 203 is in an open state, and the end away from the filter section 203 is in a closed state, thus the airway hole 202a is formed as a blind hole.

[0094] The second option: Please refer to [link / reference] Figure 4 and Figure 8 The air passage 202a passes through both ends of the medium section 202 along the axial direction. That is to say, the end of the air passage 202a near the filter section 203 is open, and the end away from the filter section 203 is also open. The air passage 202a is formed as a through hole.

[0095] The number of airway orifices 202a is unlimited; there can be one, two, or more.

[0096] Here, the axial direction is parallel to the length direction of the aerosol generating article 20. In this embodiment, the arrangement direction of the stop 201, the medium section 202 and the filter section 203 is consistent with the axial direction, and the axial direction of the receiving cavity 11a is consistent with the length direction of the aerosol generating article 20.

[0097] In some embodiments, please refer to Figure 8 The aerosol generating article 20 includes a coating layer 204, which wraps around the periphery of the stop 201, the medium section 202, and the filter section 203.

[0098] For example, during the manufacturing process, the wrapping layer 204 can be directly wrapped around the outer periphery of the stop 201, the medium section 202, and the filter section 203 by a roll-fitting process, so as to integrate the stop 201, the medium section 202, and the filter section 203 together, thereby improving the structural strength of the aerosol generation article 20, reducing the probability of the parts of the aerosol generation article 20 separating and failing during transportation and use, increasing the reliability of the aerosol generation article 20, and also reducing the probability of aerosol leakage.

[0099] Understandably, the material of the coating layer 204 has a certain structural strength to reduce the probability of deformation of the aerosol-generated product 20 due to airflow pressure during use. The coating layer 204 can be a one-piece structure or a composite structure.

[0100] The specific material of the wrapping layer 204 is not limited, such as one or more combinations of materials such as fiber paper, metal foil, metal foil composite fiber paper, PE (Polyethylene), polyethylene composite fiber paper, PBAT (Poly(butylene adipate-co-terephthalate)).

[0101] For example, the wrapping layer 204 is aluminum foil.

[0102] In some embodiments, please refer to Figure 4 and Figure 15 Each cavity 11a corresponds to a heating element 111.

[0103] That is, in each receiving cavity 11a, the aerosol generating article 20 is heated by a heating element 111. Thus, the structure of the heating assembly 11 is simple and it is easy to increase the heating consistency.

[0104] The specific construction of the switching mechanism 12 is not limited.

[0105] In some embodiments, please refer to Figure 2 The housing 10 forms a circumferential groove 10c, one side of which is open. A plurality of air inlets 10b penetrate the groove wall of the groove 10c, exemplarily penetrating the groove wall away from its open side. The plurality of air inlets 10b are spaced apart along the extension direction of the groove 10c.

[0106] The switching mechanism 12 includes a sliding component that is slidably disposed in the slide groove 10c. The sliding component can slide along the slide groove 10c relative to the air inlet 10b to avoid exposing one of the air inlets 10b to the outer surface of the housing 10 and to block the other air inlets 10b.

[0107] In this embodiment, the opening of one air inlet 10b and the closing of the other air inlets 10b are achieved by sliding the sliding component relative to the slide groove 10c.

[0108] Here, multiple air inlets 10b penetrate the groove wall of the slide groove 10c and are exposed on the outer surface of the slide groove 10c. When the sliding component opens one of the air inlets 10b, the air inlet 10b can be seen from the outer surface of the slide groove 10c. The slide groove 10c can provide movement space for the sliding component and make the sliding component move along a preset trajectory without detaching.

[0109] When the sliding component slides within the groove 10c, each movement of the sliding component avoids one of the air inlets 10b. That is, at this point, the sliding component does not overlap with the air inlet 10b, so the air inlet 10b is visible from the outer surface of the aerosol generating device. Under negative pressure, air from the external environment can enter its corresponding receiving cavity 11a through the air inlet 10b. At this time, the sliding component can overlap with the remaining air inlets 10b, thereby closing them. At this point, the remaining air inlets 10b are not visible from the outer surface of the aerosol generating device, and the connection between the remaining air inlets 10b and the external environment is closed by the sliding component. Air from the external environment will not affect the quality of the aerosol-generated product 20 corresponding to the remaining air inlets 10b.

[0110] In this embodiment, the switching of each air inlet 10b is achieved by sliding the sliding component relative to the sliding groove 10c on the housing 10, thereby realizing the suction switching of different aerosol generating products 20. The operation is convenient, and the sliding component does not need to occupy much space, making the structure of the aerosol generating device simple.

[0111] The specific construction of the sliding component is not limited.

[0112] In some embodiments, please refer to Figure 2 The sliding assembly includes at least one slider 121, which blocks an air inlet 10b.

[0113] It is understandable that when there are two air inlets 10b, the sliding assembly can include a slider 121. By moving the slider 121 in the groove 10c, one air inlet 10b can be avoided, and the other air inlet 10b can be blocked, thereby achieving the switching of heating for different aerosol-generating products 20. When there are three air inlets 10b, the sliding assembly can include two sliders 121. That is, the number of sliders 121 is one less than the number of air inlets 10b.

[0114] In this embodiment, the slider 121 makes the switching mechanism 12 simple in structure and easy to assemble. It can achieve effective switching with just a simple sliding operation, thereby increasing the structural reliability of the aerosol generating device.

[0115] In other embodiments, please refer to Figure 10 and Figure 11 A portion of the outer surface of the housing 10 is recessed inward to form an annular groove 10d. One side of the annular groove 10d is open, and a plurality of air inlets 10b penetrate the groove wall of the annular groove 10d. Exemplarily, they penetrate the groove wall of the annular groove 10d away from its open side, and the plurality of air inlets 10b are spaced apart along the extending direction of the annular groove 10d.

[0116] The switching mechanism 12 includes an intake ring 122, which is correspondingly disposed in the annular groove 10d. The intake ring 122 has a connecting port 122a, which is used to connect to the external environment. The intake ring 122 can rotate along the extension direction of the annular groove 10d so that the connecting port 122a connects with one of the air inlets 10b and blocks the other air inlets 10b.

[0117] In this embodiment, the opening of one air inlet 10b and the closing of the other air inlets 10b are achieved by rotating the air inlet ring 122 relative to the ring groove 10d.

[0118] The annular groove 10d provides space for the intake ring 122 to move and allows the intake ring 122 to rotate along a preset trajectory without disengaging.

[0119] When the intake ring 122 rotates at the annular groove 10d, it can rotate a certain distance to connect the connecting port 122a with one of the intake ports 10b, allowing air from the external environment to enter the intake port 10b through the connecting port 122a and thus into the corresponding receiving cavity 11a. At this time, the other parts of the intake ring 122 overlap with the remaining intake ports 10b, i.e., they block the remaining intake ports 10b. The remaining intake ports 10b are not connected to the connecting port 122a, meaning that the connection with the external environment is closed by the intake ring 122. Air from the external environment will not affect the quality of the aerosol-generated product 20 corresponding to the remaining intake ports 10b.

[0120] In this embodiment, the air inlet ring 122 rotates relative to the annular groove 10d on the housing 10, enabling communication between different air inlets 10b and the connecting port 122a. This allows for switching between different aerosol-generating products 20, making operation convenient and the rotation method simple. Furthermore, it provides good shielding and requires minimal additional space. The structure of the air inlet ring 122 is compatible with the annular groove 10d, ensuring that the outer surface of the aerosol generating device has no recesses or protrusions, reducing the impact on the device's appearance.

[0121] In some embodiments, please refer to Figures 5 to 6 , Figures 12 to 15 The aerosol generating device includes a drive mechanism 14, which is disposed in the mounting cavity 10a and electrically connected to the power supply assembly 13. The heating element 111 corresponding to each receiving cavity 11a is connected to the drive mechanism 14. The drive mechanism 14 is used to drive the heating element 111 to move along the axial direction of the receiving cavity 11a to heat the aerosol generating product 20 segment by segment.

[0122] The power supply component 13 can serve as the energy source for the drive mechanism 14, enabling the drive mechanism 14 to generate driving force and drive the heating element 111 to move axially along the receiving cavity 11a.

[0123] In this embodiment, the heating element 111 corresponding to each receiving cavity 11a is connected to the driving mechanism 14. That is, under the driving action of the driving mechanism 14, regardless of whether the air inlet 10b corresponding to the receiving cavity 11a is inlet or not, all the heating elements 111 can move along the axial direction of the aerosol generating product 20 under the action of the driving mechanism 14. The power supply component 13 can disconnect the conductive connection of the heating element 111 corresponding to the receiving cavity 11a that is not inlet, and connect the conductive connection of the heating element 111 corresponding to the receiving cavity 11a that is inlet. In this way, all the heating elements 111 move synchronously under the drive of the driving mechanism 14, with good motion consistency, reducing motion complexity, and there is no need to worry about the heating of the heating element 111 that is not inlet.

[0124] In this embodiment, the heating element 111 is driven to move along the axial direction of the receiving cavity 11a by the driving mechanism 14, so that the heating element 111 can heat the aerosol generating product 20 in segments, which can increase the consistency of taste and improve the user experience.

[0125] It is understandable that the axial length of a single aerosol generating product 20 is greater than or much greater than the axial length of the heating element 111. In this way, by moving the heating element 111 to heat it, the user can inhale fresh heated aerosol each time, resulting in a better taste.

[0126] For example, in an embodiment with a drive mechanism 14, one receiving cavity 11a corresponds to one heating element 111, which can increase the reliability of segmented heating and make the drive method simpler and more reliable.

[0127] Of course, in this embodiment, the structure and size of the heating element 111 can also be smaller, which makes it easier to install and heat, reduces manufacturing costs and starting power, and allows for faster heating, making it easier to achieve suction without waiting, and further enhancing the user experience.

[0128] The arrangement of the heating component 11 and the drive mechanism 14 is not limited.

[0129] In some embodiments, please refer to Figures 4 to 6 Multiple heating components 11 are arranged side by side in a straight line along a first direction and spaced apart in the mounting cavity 10a. The driving mechanism 14 is disposed on one side of the multiple heating components 11 along a second direction, wherein the second direction is perpendicular to the first direction.

[0130] In this embodiment, multiple heating components 11 are arranged linearly within the mounting cavity 10a, making the structure intuitive. The driving mechanism 14 is located on one side of the multiple heating components 11 along the second direction, so that it is connected to the heating element 111 of each heating component 11 to drive the movement of each heating element 111, but does not affect the arrangement of the heating components 11.

[0131] Here, the first direction and the second direction can be mutually perpendicular to the axis of the aerosol generating article 20. The axis of the aerosol generating article 20 is the same as the axis of the receiving cavity 11a.

[0132] In this embodiment, when the number of aerosol-generating products 20 is small, the layout of the heating components 11 can be reasonable and intuitive, and the dimensions of the aerosol generating device in each direction can be more reasonable, which facilitates the flattening design of the aerosol generating device.

[0133] In other embodiments, please refer to Figures 13 to 15 Multiple heating components 11 are arranged circumferentially in the mounting cavity 10a, and the drive mechanism 14 is disposed in the space formed by the multiple heating components 11.

[0134] In this embodiment, multiple heating components 11 are arranged circumferentially to roughly enclose an annular space. The driving mechanism 14 is located within the space enclosed by the multiple heating components 11, which makes it easier for the driving mechanism 14 to be located in the central area of ​​the annular space. This makes the connection distance between the driving mechanism 14 and each heating element 111 more consistent, which facilitates connection with each heating element 111 and increases connection consistency and driving consistency.

[0135] In this embodiment, the connection between the drive mechanism 14 and the heating element 111 is more convenient. Simultaneously, it increases the rationality of the layout of the heating component 11 and the drive mechanism 14. When the number of aerosol-generating products 20 is large, space can be rationally utilized for arrangement, facilitating the miniaturization design of the aerosol-generating device. In this embodiment, the outer contour of the aerosol-generating product 20 can be approximately cylindrical.

[0136] The specific structure of the drive mechanism 14 is not limited.

[0137] In some embodiments, please refer to Figures 5 to 6 , Figures 13 to 15The drive mechanism 14 includes a motor 141, a bracket 142 and a moving part 143. The bracket 142 is fixed in the mounting cavity 10a. The bracket 142 includes at least one support rod 1421. The moving part 143 is sleeved on at least one support rod 1421. The motor 141 is used to drive the moving part 143 to move axially up and down along the support rod 1421 relative to the receiving cavity 11a.

[0138] The drive mechanism 14 also includes a connector 144, which is used to connect the end of each heating element 111 away from the receiving cavity 11a. The connector 144 is connected to the moving element 143 so that the heating element 111 can be moved under the drive of the moving element 143.

[0139] The bracket 142 is used to provide mounting support for the motor 141, the moving part 143, etc. The motor 141 is used to provide driving force to drive the moving part 143 to move on the support rod 1421. The support rod 1421 can position and restrict the movement of the moving part 143, reducing the probability of the moving part 143 coming off or deviating from its position.

[0140] The number of support rods 1421 can be one or more, and there is no restriction here.

[0141] The connector 144 connects the heating elements 111 corresponding to each receiving cavity 11a, so that each heating element 111 can be moved up and down along the axial direction under the drive of the moving member 143, thereby achieving reliable segmented heating.

[0142] In this embodiment, the heating elements 111 are connected by the connector 144 to form a linkage, which makes it easy for the motor 141 to drive the moving part 143 to move, and drive the linkage to move in a unified manner, increasing the reliability of the movement, and eliminating the need to worry about whether the heating element 111 that needs to be heated has moved into place.

[0143] Motor 141 can be a stepper motor, which has high motion precision.

[0144] The specific structure of the heating component 11 is not limited.

[0145] In some embodiments, please refer to Figures 5 to 7 The heating assembly 11 includes a heating cylinder 112, which is hollow. The space inside the heating cylinder 112 defines a receiving cavity 11a, and the heating element 111 is sleeved on the outer periphery of the heating cylinder 112.

[0146] It is understandable that the space inside the heating cylinder 112 is used for inserting the aerosol generating product 20. The heating cylinder 112 can protect the aerosol generating product 20, so that the position of the aerosol generating product 20 inside the heating cylinder 112 is fixed and its shape is maintained.

[0147] It is understandable that the heating cylinder 112 is a structure that can concentrate the heat of the heating element 111. The heating cylinder 112 has a low heat capacity and stores little heat. It can transfer the heat from the heating element 111 to the aerosol generating product 20 that comes into contact with it.

[0148] In this embodiment, the heating element 111 is sleeved on the outer periphery of the heating cylinder 112, meaning that the heating element 111 does not directly contact the aerosol generating product 20. On the one hand, the heat from the heating element 111 is transferred through the heating cylinder 112 to the segments of the aerosol generating product 20 that need to be heated, thereby increasing the temperature consistency of the segmented heating of the aerosol generating product 20 and facilitating faster heat transfer rate of segmented heating. On the other hand, the fact that the heating element 111 does not directly contact the aerosol generating product 20 reduces contamination of the heating element 111, meaning that there is no need to clean the heating element 111. At the same time, it can also reduce the occurrence of debris falling off or local blackening caused by the movement or heating of the heating element 111 during direct contact, resulting in better heating reliability.

[0149] In some embodiments, please refer to Figure 7 The heating cylinder 112 is provided with a plurality of heat insulation grooves 112a, which are spaced apart along the circumference and / or axial direction of the heating cylinder 112.

[0150] For example, the plurality of heat insulation grooves 112a may be arranged only circumferentially along the heating cylinder 112, or only axially along the heating cylinder 112, or both circumferentially and axially. For example, the plurality of heat insulation grooves 112a are arranged circumferentially and axially along the heating cylinder 112, and the heating cylinder 112 is generally formed into a dumbbell-shaped structure.

[0151] In this embodiment, the heat insulation groove 112a can concentrate and isolate the heat of the segmented heated aerosol generating product 20, interrupt the heat conduction path, reduce heat conduction and thus reduce the impact on the segmented aerosol generating product 20 that does not need to be heated, so that the heat of the aerosol generating product 20 in the segment where the heating element 111 is located is concentrated and reduced to escape to other segments.

[0152] Of course, in other embodiments, please refer to Figure 12 and Figure 15 The heating cylinder 112 may also be without the heat insulation groove 112a, and there is no restriction here.

[0153] In some embodiments, the heating cylinder 112 has a flared opening 112b formed on one side along the axial direction.

[0154] The flared opening 112b is used to guide the aerosol-generated product 20 into the heating cylinder 112. Along the axial direction towards the other side of the heating cylinder 112, the diameter of the flared opening 112b gradually decreases.

[0155] In this embodiment, the flared opening 112b serves to guide the insertion of the aerosol generating article 20, facilitating insertion and increasing insertion reliability. It also helps determine from which end the aerosol generating article 20 should be inserted during installation. The diameter of the flared opening 112b gradually decreases axially towards the other side of the heating cylinder 112, reducing insertion resistance initially, limiting the position of the aerosol generating article 20 after insertion, and facilitating removal of the aerosol generating article 20 from the flared opening 112b when needed.

[0156] In some embodiments, please refer to Figure 5 , Figure 6 and Figure 15 The heating assembly 11 includes a reflector 113, which is sleeved on the outer periphery of the heating cylinder 112 and is used to reflect heat back to the heating cylinder 112 during heating.

[0157] In this embodiment, the reflector 113 is designed to reflect the heat overflowing from the heating element 111 and the heating cylinder 112 back to the heating cylinder 112 when the heating element 111 is heating, thereby reducing heat loss, increasing the consistency of heating temperature, and improving the heating rate. This facilitates immediate extraction without waiting and enhances the user experience.

[0158] The reflector 113 can be made of a metal surface with high reflectivity, such as silver plating, aluminum plating, etc. Of course, it can also be coated with a special reflective coating to increase the reflectivity.

[0159] For example, the reflector 113 is provided with a relief groove 113a in the circumferential direction, one end of the heating element 111 is sleeved on the outer periphery of the heating cylinder 112, and the other end passes through the relief groove 113a and is connected to the drive mechanism 14.

[0160] The recess 113a of the reflector 113 facilitates the connection between the heating element 111 and the drive mechanism 14. At the same time, it reduces the probability of interference with the heating element 111 when it moves, and increases the installation reliability of the heating element 111.

[0161] In some embodiments, please refer to Figure 5 , Figure 6 and Figure 15 The aerosol generating device also includes multiple heat insulation covers 15. One heat insulation cover 15 is fitted around the outer periphery of a reflector 113. The drive mechanism 14 is located on the outside of the heat insulation cover 15. The heating element 111 passes through the clearance groove 113a. The heat insulation cover 15 is connected to the drive mechanism 14.

[0162] In this embodiment, the heat insulation cover 15 can provide heat insulation and heat preservation, so that the heat is concentrated in the reflector 113, thereby achieving extraction without waiting. The heating cylinder 112 has a fast heating rate, so as to quickly heat the segmented aerosol generation product 20 and improve heating efficiency.

[0163] Here, multiple insulation covers 15 can isolate each heating component 11, that is, enable each heating component 11 to work independently.

[0164] Multiple insulation covers 15 can be of a separate structure; please refer to [link / reference]. Figure 15 That is, each insulation cover 15 can be independently docked with the reflector 113. Of course, please refer to [the relevant documentation]. Figure 6 Multiple heat insulation covers 15 can also be an integrated structure, that is, multiple heat insulation covers 15 are molded as one piece and docked with the reflector 113 as a whole structure.

[0165] In some embodiments, the heating cylinder 112 is a metal part or a transparent quartz part.

[0166] The high structural strength of the metal or transparent quartz parts makes it easy for the heating element 111 to be fitted outside the heating cylinder 112 and to be less prone to deformation when the heating element 111 moves. At the same time, the low heat capacity of the metal or transparent quartz parts makes it easy to transfer heat to the aerosol generating product 20 and increase the heating rate.

[0167] For example, the heating cylinder 112 can be made of stainless steel.

[0168] The thickness of the heating cylinder 112 is 0.1mm to 0.2mm, for example, 0.1mm, 0.11mm, 0.12mm, 0.13mm, 0.14mm, 0.15mm, 0.16mm, 0.17mm, 0.18mm, 0.19mm, 0.2mm, etc.

[0169] In this embodiment, the thickness of the heating cylinder 112 is appropriate, which not only provides sufficient structural strength but also facilitates heat transfer and improves the heating rate.

[0170] In some embodiments, please refer to Figure 16 The heating element 111 is a one-piece structure.

[0171] The heating element 111 includes a heating wire 1112 and a substrate ceramic 1111, with the heating wire 1112 disposed on the substrate ceramic 1111.

[0172] In this embodiment, the ceramic substrate 1111 reduces the probability of deformation of the heating wire 1112, thereby making the overall structure of the heating element 111 highly stable and easy to move stably under the drive of the driving mechanism 14.

[0173] The heating wire 1111 can be set on the substrate ceramic 1111 by means of embedding, winding or other methods.

[0174] For example, the diameter of the heating wire 1112 can be 0.1mm to 0.5mm, such as 0.1mm, 0.15mm, 0.17mm, 0.2mm, 0.22mm, 0.25mm, 0.3mm, 0.31mm, 0.39mm, 0.4mm, 0.45mm, 0.5mm, etc. In this way, the heating wire 1112 can have a high heating rate while being easy to manufacture.

[0175] For example, the heating wire 1112 can be a nickel-chromium wire, which is integrally sintered into a low-heat-capacity substrate ceramic 1111.

[0176] Of course, in some embodiments, the heating element 111 can also be a metal ring.

[0177] In some embodiments, please refer to Figure 5 and Figure 17 The aerosol generating device includes a suction nozzle 16, which is provided with a transfer channel 16a and an exhaust channel 16b. The transfer channel 16a is located upstream of the exhaust channel 16b along the airflow direction. There are multiple transfer channels 16a, which are not interconnected but are connected to the exhaust channel 16b respectively. Each transfer channel 16a is connected to a receiving cavity 11a.

[0178] Here, the user can generate a suction negative pressure through the nozzle 16 to allow air from the external environment to enter the corresponding receiving cavity 11a from the air inlet 10b.

[0179] The suction nozzle 16 can be axially mated with each heating component 11 and axially abut against the housing 10.

[0180] The fact that multiple transfer channels 16a are not interconnected means that multiple transfer channels 16a exit air independently and there will be no aerosol mixing.

[0181] In this embodiment, the multiple transfer channels 16a are configured to correspond one-to-one with the receiving cavity 11a, so that the aerosol flowing out of the heated receiving cavity 11a flows through the corresponding transfer channel 16a to the gas outlet channel 16b and is inhaled by the user, thereby reducing contamination of other receiving cavities 11a, increasing the reliability of gas outlet, and also increasing the consistency of suction.

[0182] It is understood that the nozzle 16 can be a one-piece structure or a split structure. That is, the nozzle 16 can include a first part and a second part with a split design. The first part can form an air outlet channel 16b, and the second part can form multiple non-interconnected transition channels 16a.

[0183] In this embodiment, aerosol products 20 with various flavors can be generated and flow to the gas outlet channel 16b through the corresponding transfer channel 16a, and be inhaled by the user to achieve multi-flavor inhalation and enhance the user experience.

[0184] In the description of this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application.
