[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, the aerosol generated by a single aerosol generating device can only be inhaled a limited number of times, requiring users to manually replace the aerosol generated product multiple times, which is inconvenient and results in a poor user experience.

[0006] The shell has a receiving cavity;

[0007] The power supply assembly is disposed within the receiving cavity;

[0008] The heating assembly includes two separately designed heating structures, which are spaced apart along a first direction and form a heating space for the aerosol-generated product to pass through. The two heating structures are electrically connected to the power supply assembly.

[0009] A driving component is disposed within the receiving cavity and connected to the heating assembly;

[0010] A drive mechanism is disposed within the receiving cavity and connected to the heating assembly;

[0011] The aerosol generating device has a first state and a second state.

[0012] In the first state, the driving member drives the two heating structures to move closer to each other along the first direction, so as to approach or clamp the aerosol generating article and heat the part of the aerosol generating article located in the heating space.

[0013] In the second state, the driving member drives the two heating structures to move away from each other along the first direction to move away from or release the aerosol generating article. The driving mechanism drives the heating component and the driving member to move along the length direction of the aerosol generating article, wherein the first direction intersects the length direction of the aerosol generating article.

[0014] In some embodiments, the driving element includes an electromagnet disposed on at least one of the two heating structures.

[0015] In some embodiments, the driving element further includes an elastic element disposed between the two heating structures. In the first state, the electromagnet is energized to drive the two heating structures to move closer to each other along the first direction, and the elastic element stores energy. In the second state, the electromagnet is de-energized, and the elastic element drives the two heating structures to move away from each other along the first direction.

[0016] In some embodiments, the number of driving elements is at least one, each driving element includes two electromagnets, the two electromagnets are respectively disposed on the same side of the two heating structures along the second direction, the elastic element is connected between the two electromagnets, and the driving mechanism is connected to at least one heating structure;

[0027] The aerosol generating device provided in this application embodiment achieves segmented aerosol generation by repeatedly switching between a first and second state. The heating structure achieves rapid heating by approaching or clamping the aerosol generating product, resulting in a large heating area and a fast heating rate. Simultaneously, each heating operation involves a small segment of the aerosol generating product, facilitating immediate aerosol generation without waiting.

[0046] This application provides an aerosol generating device.

[0047] Please see Figures 1 to 7 The aerosol generating device includes a housing 10, a power supply component 12, a heating component 11, a driving component 15, and a driving mechanism 13.

[0048] The housing 10 has a receiving cavity 10a. The power supply assembly 12 is disposed within the receiving cavity 10a.

[0049] The heating assembly 11 includes two separate heating structures 111, which are spaced apart along a first direction and form a heating space 11a. The heating space 11a is used for part of the aerosol-generated product 20 to pass through. The two heating structures 111 are electrically connected to the power supply assembly 12 respectively.

[0050] The drive component 15 is disposed within the receiving cavity 10a and connected to the heating assembly 11. The drive mechanism 13 is disposed within the receiving cavity 10a and connected to the heating assembly 11.

[0051] The aerosol generating device has a first state and a second state.

[0052] In the first state, the drive member 15 drives the two heating structures 111 to move closer to each other along the first direction, so as to approach or clamp the aerosol generating article 20 and heat the part of the aerosol generating article 20 located in the heating space 11a.

[0053] In the second state, the drive member 15 drives the two heating structures 111 to move away from each other along the first direction, so as to move away from or release the aerosol generating article 20, and the drive mechanism 13 drives the heating assembly 11 and the drive member 15 to move along the length direction of the aerosol generating article 20.

[0054] The first direction intersects with the length direction of the aerosol-generating product 20.

[0055] The housing 10 serves as the exterior component of the aerosol generating device, providing protection for the internal heating components 11, power supply components 12, drive mechanism 13, and drive components 15, thereby reducing the likelihood of impact damage to the heating components 11, power supply components 12, drive mechanism 13, and drive components 15.

[0056] The power supply assembly 12 is used to provide electrical energy to electrical components such as the heating assembly 11.

[0057] The two separate heating structures 111 refer to two heating structures 111 manufactured separately and then assembled. The two heating structures 111 can work independently. Each heating structure 111 can be an integral structure or a separate structure, and there is no restriction here.

[0058] The spacing between the two heating structures 111 along the first direction defines a heating space 11a, allowing a portion of the aerosol-generating article 20 to pass through. The heating structures 111 can heat and atomize the portion of the aerosol-generating article 20 located within the heating space 11a. The heating space 11a can only accommodate a portion of the aerosol-generating article 20, with the other portion located outside the heating space 11a.

[0059] The aerosol-generated product 20 has a length dimension that is larger than the length dimension of the heating space 11a.

[0060] The first direction can form an acute angle, a right angle, or an obtuse angle with the length direction of the aerosol generating article 20. For example, the first direction can be perpendicular to the length direction of the aerosol generating article 20, and the length direction of the aerosol generating article 20 can be parallel to the axis of the aerosol generating device.

[0061] It should be noted that the length direction of the aerosol generating article 20 is the direction in which the aerosol generating article has the longest dimension in all dimensions, that is, the aerosol generating article 20 has the largest dimension in the length direction.

[0062] For example, in an embodiment where the outer contour of the aerosol generating article 20 is generally rectangular, the length of the aerosol generating article 20 is greater than the width of the aerosol generating article 20 and the thickness of the aerosol generating article 20. The first direction can be parallel to the thickness direction of the aerosol generating article 20. In the first state, the heating structure 111 can move along the first direction to mate with the two side surfaces of the aerosol generating article 20 along the thickness direction, that is, mate with the large surface. In this way, the heating area is larger, the heating rate is faster, and the heating uniformity is high.

[0063] The heating structure 111 can heat the aerosol generating article 20 in any way. For example, it can be resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, air heating, electric field heating, carbon source heating, etc. There are no restrictions here. In this embodiment, the aerosol generating article 20 is described as being drawn in a way that is heated but not burned.

[0064] A portion of the aerosol generating article 20 is located in the heating space 11a. The heating structure 111 is able to bake and heat the portion of the aerosol generating article 20 located in the heating space 11a from the outside to the inside.

[0065] It is understood that in the embodiments of this application, the aerosol generating article 20 has a solid structure.

[0066] The outer contour of the aerosol-generated product 20 can be cylindrical, cuboid, etc., and there are no restrictions here.

[0067] The aerosol generating article 20 can be made from the aerosol generating matrix itself, such as a smoky flavoring medium; in other embodiments, the aerosol generating article 20 may also include a matrix and an aerosol generating matrix disposed on the matrix. The matrix may be one or more of high-temperature resistant carbon fiber, softwood pulp fiber, hardwood pulp fiber, bamboo fiber, cotton fiber, and hemp fiber. In this way, by setting a matrix, the strength of the aerosol generating article 20 can be improved, making it less prone to deformation and breakage, and it can also withstand a certain degree of high temperature without producing odor.

[0068] The aerosol-generated product 20 can be a one-piece structure, for example, a one-piece structure 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-generated product 20 is a one-piece extruded structure. Thus, the aerosol-generated product 20 remains a one-piece medium whether it is heated and aspirated or after heating ceases, making it less prone to disintegration and shedding. This reduces the phenomena such as flake detachment, filamentous component shedding, and particulate component shedding that occur in filamentous or loose particle aerosol-generated products in related technologies, resulting in high atomization reliability.

[0069] In the first state, under the action of the driving component 15, the two heating structures 111 approach each other along the first direction, and the heating space 11a gradually decreases. The two heating structures 111 approach or clamp the aerosol generating product 20, and under the power supply of the power component 12, heat the portion of the aerosol generating product 20 located in the heating space 11a to generate aerosol. In the first state, the gap between the heating structure 111 and the aerosol generating product 20 is small or non-existent. The heating structure 111 can quickly heat the aerosol generating product 20. The heating area of ​​the heating structure 111 is large, and the heating rate is fast, which facilitates the rapid generation of aerosol and enables extraction without waiting.

[0070] It should be noted that, in the first state, the two heating structures 111 approach or clamp the aerosol-generating article 20, including various situations.

[0071] The first method involves a small gap between the two heating structures 111 and the aerosol-generating product 20. In this case, the two heating structures 111 do not exert any force on the aerosol-generating product 20. This results in a faster heating rate and reduces damage to the aerosol-generating product 20 caused by the heating structures 111.

[0072] The second method involves two heating structures 111 that are in contact with the aerosol-generating article 20 but do not exert any force on it. This reduces damage to the aerosol-generating article 20 caused by the heating structures 111 while further increasing the heating rate.

[0073] The third method involves two heating structures 111 in close contact with the aerosol-generating product 20, exerting a clamping force on it. This ensures that the heating structures 111 have sufficient heating efficiency while providing structural support and positioning for the aerosol-generating product 20, thus fixing its position and facilitating stable heating, reducing the impact of external vibrations on the heating process.

[0074] After the heating structure 111 has finished heating part of the aerosol generating product 20 located in the heating space 11a, the aerosol generating device can be switched to the second state. The driving member 15 drives the two heating structures 111 to move away from each other along the first direction. During the process of the two heating structures 111 moving away from each other, the heating space 11a gradually recovers, and the two heating structures 111 move away from or release the aerosol generating product 20.

[0075] It should be noted that the two heating structures 111 moving away from or loosening from the aerosol generating product 20 can mean that the two heating structures 111 are in contact with the aerosol generating product 20 but do not generate clamping force, or that the two heating structures 111 are separated from the aerosol generating product 20 along the first direction. No restrictions are imposed here.

[0076] After the two heating structures 111 move away from or release from the aerosol generating product 20, the drive mechanism 13 can drive the heating component 11 and the drive element 15 to move along the length of the aerosol generating product 20, so that the unheated segment of the aerosol generating product 20 is located in the heating space 11a, ready for the next atomization. In this way, the aerosol generating device repeatedly switches between the first state and the second state, in a cycle, to achieve segmented heating of the aerosol generating product 20. The overall length of the aerosol generating product 20 can be relatively long to achieve a large number of puffs. The segmented heating method facilitates the rapid generation of aerosols while ensuring that the user inhales fresh aerosol generating product 20 each time, resulting in a good consistency in taste. In addition, after the heating structure 111 moves away from or releases from the aerosol generating product 20, the drive mechanism 13 drives the heating component 11 and the drive element 15 to move, which can reduce damage to the aerosol generating product 20 during movement. At the same time, the aerosol generating product 20 will not interfere with the movement of the heating structure 111, making the movement of the heating structure 111 smoother and more reliable.

[0077] It should be noted that in the first state, the heating structure 111 moves along the first direction, and the driving mechanism 13 does not generate a driving force on the heating structure 111; only the driving member 15 generates a driving force on the heating structure 111. In both the first and second states, the heating structure 111 can be always electrically connected to the power supply component 12, or in the second state, the electrical connection with the power supply component 12 can be disconnected; no limitation is made here.

[0078] The drive component 15 is connected to the heating assembly 11, and can be connected to one or both heating structures 111. The drive mechanism 13 is connected to the heating assembly 11, and can be connected to one or both heating structures 111.

[0079] The driving force source of the drive mechanism 13 can be the power supply component 12. That is, the power supply component 12 can disconnect the electrical connection with the drive mechanism 13 in the first state and connect the electrical connection with the drive mechanism 13 in the second state. The specific implementation method is not limited here. The driving force source of the drive component 15 can also be the power supply component 12. In this way, the drive mechanism 13 and the drive component 15 can share a single driving force source, making the structure of the aerosol generating device simpler.

[0080] The aerosol generating device provided in this application embodiment achieves segmented inhalation of the aerosol generating product 20 by repeatedly switching between a first state and a second state. The heating structure 111 achieves rapid heating by approaching or clamping the aerosol generating product 20, resulting in a large heating area and a fast heating rate. Simultaneously, each heating operation involves a small segment of the aerosol generating product 20, facilitating immediate inhalation without waiting. After inhaling the small segment of the aerosol generating product 20, the device can be moved away from or released from the aerosol generating product 20 and moved along its length to place the next segment of the aerosol generating product 20 within the heating space 11a for the next round of heating and atomization. Thus, the user inhales fresh aerosol each time, resulting in consistent taste. A single aerosol generating product 20 can have a relatively long size, enabling a large number of inhalations. It is convenient for users to carry, eliminating the need for repeated disassembly and reassembly of the aerosol generating product 20, and reducing the risk of damage by eliminating the need to move the aerosol generating product 20.

[0081] Understandably, the atomization time of a segment of aerosol generating product 20 can be set so that after the corresponding atomization time, it is determined that the aerosol generating matrix contained in that segment of aerosol generating product 20 has been consumed, and the aerosol generating device can switch to the second state. Of course, the number of suction ports can also be set so that the device switches to the second state after a certain number of suction ports. Alternatively, an atomization medium detection mechanism can be installed so that when the aerosol generating product 20 content in a segment of aerosol generating product 20 approaches zero, the aerosol generating device can switch to the second state based on this detection signal. No restrictions are imposed here.

[0082] Please see Figures 1 to 3 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 a portion of the aerosol generation article 20 passes through a heating space 11a.

[0083] It is understandable that the number of suction ports of a single aerosol generating product 20 can be set and calculated. In this embodiment, the size of a single aerosol generating product 20 is relatively long, which can achieve more than one hundred suction ports, thereby facilitating multiple suctions by the user.

[0084] For example, in some embodiments, please refer to Figure 8 The aerosol generating product 20 has an elongated structure. This allows it to easily cooperate with the heating structure 111, so that the two heating structures 111 can clamp the aerosol generating product 20 tightly and prevent it from loosening, thereby achieving stable and uniform heating.

[0085] In other embodiments, the aerosol generating article 20 is in sheet form. This facilitates faster aerosol generation and enables immediate extraction without waiting.

[0086] In some embodiments, please refer to Figure 8 The aerosol generating article 20 has at least one air passage 20a extending along its length.

[0087] In this way, the aerosol generated by the aerosol-generating product 20 through heating and atomization can be directly released from the air passage 20a, and the aerosol has sufficient release space, thereby improving the utilization rate of the aerosol.

[0088] The number of airway orifices 20a can be one or more; for example, the number of airway orifices 20a is multiple.

[0089] Understandably, the aerosol generating article 20 may also contain micropores, which are interconnected to form microchannels. Some of the micropores are connected to the channel holes 20a, while other microchannels directly pass through both ends of the aerosol generating article 20. This allows the aerosol to be discharged from the aerosol generating article 20 in multiple ways. For example, the aerosol generated by the aerosol generating article 20 after heating can directly enter the channel holes 20a and be carried out by air in the external environment; or, air in the external environment can directly enter the microchannels and carry out the aerosols entrained in the microchannels; or, the aerosol can enter the channel holes 20a from the microchannels.

[0090] It is understandable that the interconnection between micropores can be partial or non-interconnected, or all micropores can be interconnected. For example, in an embodiment where the aerosol generating article 20 is a particle aggregate, the gaps between the particles constitute micropores, wherein the size of the micropores is determined by the gaps between the particles of the aerosol generating article 20.

[0091] It should be noted that the airway orifice 20a is a macroscopic orifice that can be seen with the naked eye, while the micropore is a pore in a peripheral sense that cannot be seen with the naked eye.

[0092] The air passage pores 20a and micropores can increase the surface area of ​​the aerosol generating product 20, facilitating heat transfer and improving heating efficiency. When the aerosol generating matrix inside the aerosol generating product 20 is heated, it releases aerosols. Under the negative pressure generated by the user's suction, the air passage pores 20a and micropores can reduce the suction resistance of the user's suction, improve the user experience, and reduce the adverse effects of condensed aerosol residue in the aerosol generating product 20 on airflow.

[0093] The specific structure of the drive component 15 is not limited.

[0094] For example, in some embodiments, please refer to Figures 4 to 7 The driving element 15 includes an electromagnet 151, which is disposed on at least one of the two heating structures 111.

[0095] The electromagnet 151 can be installed on one of the heating structures 111 or on two heating structures 111, and there is no limitation on this.

[0096] Taking the example of an electromagnet 151 being installed on one of the heating structures 111, the other heating structure 111 may include at least a metal part or a permanent magnet. In the first state, the electromagnet 151 is energized, and under the action of magnetic force, it drives the two heating structures 111 to approach each other, so as to approach or clamp the aerosol-generated product 20.

[0097] Taking the electromagnet 151 set on two heating structures 111 as an example, in the first state, the two electromagnets 151 are energized and attract each other under the action of magnetic force, thereby driving the two heating structures 111 to approach or clamp the aerosol generating product 20 along the first direction.

[0098] In this embodiment, the electromagnet 151 makes the cooperation between the drive component 15 and the heating structure 111 relatively simple and easy to operate. As long as the power supply component 12 is electrically connected to the electromagnet 151, the two heating structures 111 can be brought close to or clamped together to generate the aerosol product 20.

[0099] It is understandable that the movement of the two heating structures 111 away from or away from the aerosol generating article 20 can be achieved by setting the electromagnet 151, such as by magnetic repulsion, or by other structures of the drive element 15.

[0100] For example, in some embodiments, please refer to Figures 4 to 7The heating assembly 11 includes at least one elastic element 152, which is disposed between two heating structures 111. In a first state, the electromagnet 151 is energized to drive the two heating structures 111 to move towards each other along a first direction, and the elastic element 152 stores energy. In a second state, the elastic element 152 drives the two heating structures 111 to move away from each other along the first direction.

[0101] In this embodiment, in the second state, the driving member 15 can apply a driving force to the two heating structures 111 through the elastic member 152, causing the two heating structures 111 to move away from each other in a direction away from or release the aerosol generating article 20.

[0102] Specifically, in the first state, the electromagnet 151 is energized, and the two heating structures 111 move toward each other under the drive of the electromagnet 151. At this time, the elastic element 152 undergoes elastic deformation and accumulates energy. After the segmented aerosol generating product 20 is heated, the power supply component 12 disconnects the electrical connection with the electromagnet 151, the electromagnet 151 is de-energized and does not generate driving force. At this time, the elastic element 152 releases energy to drive the two heating structures 111 to move away from each other, releasing the aerosol generating product 20. Thus, the driving mechanism 13 can drive the heating structure 111 and the driving element 15 to move along the length direction of the aerosol generating product 20.

[0103] The elastic element 152 is disposed between the two heating structures 111, that is, the driving force of the elastic element 152 can act on the two heating structures 111 simultaneously, so that the two heating structures 111 can move away from each other synchronously.

[0104] In this embodiment, when switching from the first state to the second state, it is only necessary to disconnect the electrical connection between the power supply component 12 and the electromagnet 151. The heating structure 111 can then move under the action of the elastic member 152 to release the aerosol generating product 20, so that the driving mechanism 13 can drive the heating structure 111 and the driving member 15 to move to the heating space 11a to accommodate the next segment of the aerosol generating product 20. In this way, the state switching of the aerosol generating product 20 is more convenient and reliable. During the process of the driving mechanism 13 driving the heating structure 111 to move along the length direction of the aerosol generating product 20, the elastic member 152 can also fix the relative position of the two heating structures 111 along the first direction, increasing the reliability of the movement.

[0105] The elastic element 152 is a structure with elastic properties. In the first state, the elastic element 152 undergoes elastic deformation and stores energy. In the second state, the elastic element 152 recovers its deformation and keeps the heating structure 111 in a position away from or away from the aerosol generating article 20 along the first direction.

[0106] It is understood that the elastic element 152 can be connected to the electromagnet 151, and the driving force of the elastic element 152 acts on the heating structure 111 through the electromagnet 151. Alternatively, the elastic element 152 can be directly connected between two heating structures 152, and the driving force of the elastic element 152 acts directly on the heating structure 111.

[0107] In some embodiments, please refer to Figures 4 to 7 The number of driving elements 15 is at least one, and each driving element 15 includes two electromagnets 151. The two electromagnets 151 are disposed on the same side of the two heating structures 151 along the second direction, and the elastic element 152 is connected between the two electromagnets 151.

[0108] The drive mechanism 13 is connected to at least one heating structure 111.

[0109] The first direction and the second direction are perpendicular to the length direction of the aerosol-generating product 20.

[0110] In this embodiment, the driving force of the elastic element 152 is applied to the heating structure 111 through the electromagnet 151, that is, the elastic element 152 does not directly contact the heating structure 111, which can reduce the interference between the elastic element 152 and the aerosol generating product 20, facilitate stable movement and heating, and increase the overall structural reliability.

[0111] The number of driving components 15 can be one, that is, it is set on one side of the heating assembly 11 along the second direction, which makes the structure relatively simple.

[0112] In some embodiments, please refer to Figures 4 to 7 There are two drive units 15, which are connected to the two heating structures 111 on opposite sides along the second direction.

[0113] In other words, both heating structures 111 are provided with driving elements 15 on both sides along the second direction.

[0114] This allows the electromagnet 151 and the elastic element 152 to apply driving force to the heating structure 111 from both sides along the second direction, resulting in higher motion stability, reduced load on the individual driving element 15, more stable and reliable state switching of the aerosol generating device, and easier heating of the aerosol generating product 20 by the heating structure 111.

[0115] In some embodiments, please refer to Figures 4 to 7 The elastic element 152 includes a spring.

[0116] The spring has a simple structure and is easy to assemble. When the two heating structures 111 approach each other along the first direction, the spring is compressed and undergoes elastic deformation. When it is necessary to switch to the second state, the spring releases elastic potential energy, causing the two heating structures 111 to move away from each other along the first direction and remain in a position away from or away from the aerosol generating product 20. The state switching of the aerosol generating product 20 is simpler and more reliable.

[0117] The specific construction of the heating structure 111 is not limited.

[0118] In some embodiments, please refer to Figures 4 to 7 The heating structure 111 includes a fixed plate 1111 and a heating element 1112. The heating element 1112 is fixed to the side of the fixed plate 1111 facing the heating space 11a in the first direction. The driving member 15 is connected to the two fixed plates 1111 on one side in the second direction.

[0119] In this embodiment, the fixing plate 1111 provides mounting support for the heating element 1112. Simultaneously, the fixing plate 1111 is connected to the driving component 15, and the driving force of the driving component 15 acts on the heating element 1112 through the fixing plate 1111, thereby causing the heating element 1112 to move along the first direction. The fixing plate 1111 isolates the heating element 1112 from the driving component 15, reducing the impact of the heat from the heating element 1112 on the driving component 15, and also reducing the probability that the driving component 15 will affect the operation of the heating element 1112.

[0120] The fixing plate 1111 can be made of a high-temperature resistant material so as to maintain its structural strength and shape under the heating operation of the heating element 1112.

[0121] The specific shape of the heating element 1112 is not limited, and the heating element 1112 can be a heating film. The heating film is a thin conductive material, which can be flat or wrapped around the fixed plate 1111 in some form. The heating film has high heat transfer efficiency. When current passes through the heating film, heat is transferred to the aerosol generating product 20 that cooperates with the heating film, heating and atomizing the aerosol generating matrix contained in the aerosol generating product 20 to form an aerosol. The heating film can increase the uniformity of heat distribution and achieve efficient and uniform atomization.

[0122] Heating films can be made of materials such as metal alloys, ceramics, glass fibers, or carbon fibers.

[0123] The fixing plate 1111 and the heating element 1112 can be manufactured as one piece or separately.

[0124] The driving component 15 is connected to the fixed plate 1111 via an electromagnet 151. The connection method is not limited and can include bonding, welding, etc. There are no restrictions here.

[0125] The specific structure of the drive mechanism 13 is not limited.

[0126] In some embodiments, please refer to Figures 4 to 5 The drive mechanism 13 includes a motor 131, a bracket 132 and a moving part 133. The bracket 132 includes at least one support rod 1321. The moving part 133 is sleeved on the outer periphery of the support rod 1321. The moving part 133 is connected to at least one of the heating structures 111. The motor 131 is used to drive the moving part 133 to move along the support rod 1321.

[0127] For example, the movable part 133 is connected to one of the heating structures 111 on the side away from the aerosol generating article 20.

[0128] The bracket 132 can provide support for the motor 131 and the moving part 133. At the same time, the bracket 132 can also provide motion support for the movement of the moving part 133 and the heating component 11. The motor 131 is used to provide driving force to drive the moving part 133 to move on the support rod 1321. The support rod 1321 can position and restrict the movement of the moving part 133, reducing the probability of the moving part 133 getting out or moving off course.

[0129] The number of support rods 1321 can be one or more, and there is no restriction here.

[0130] The movable component 133 may be connected to only one of the heating structures 111, so that by moving one of the heating structures 111, it can drive the heating assembly 11 and the driving component 15 to move. Alternatively, the movable component 133 may be connected to both heating structures 111 simultaneously, thereby driving the heating assembly 11 and the driving component 15 to move. There is no limitation on this. In this way, the probability of interference between the driving mechanism 13 and the driving component 15 can be reduced.

[0131] The movable component 133 can be a slider or other structure, and there are no restrictions here.

[0132] Motor 131 can be a stepper motor, which has high motion precision. Motor 131 can be electrically connected to power supply component 12 to provide power to motor 131.

[0133] In this embodiment, the reliable driving and control of the movement of the heating structure 111 is achieved through the cooperation of the motor 131, the bracket 132 and the moving part 133, resulting in high movement reliability and stability.

[0134] In some embodiments, please refer to Figures 1 to 4 The aerosol generating device includes a nozzle 14, which is connected to the housing 10. The nozzle 14 has a fixing hole 14a and an air outlet channel 14b. The fixing hole 14a and the air outlet channel 14b are connected. The fixing hole 14a is used to insert one end of the aerosol generating product 20 along the length direction to fix the aerosol generating product 20.

[0135] In this embodiment, the fixing hole 14a can fix one end of the aerosol generating product 20 along its length, thus fixing the position of the aerosol generating product 20 within the receiving cavity 10a, preventing displacement and shaking, and increasing heating stability. Simultaneously, it does not obstruct the movement of the heating component 11 when it moves along the length of the aerosol generating product 20. Furthermore, the fixing hole 14a is connected to the air outlet channel 14b, allowing the aerosol generated after atomization by the aerosol generating product 20 to flow directly out through the fixing hole 14a from the air outlet channel 14b, increasing air outlet reliability and facilitating aerosol extraction for the user.

[0136] In some embodiments, please refer to Figure 3 The housing 10 is provided with an air inlet 10b, which connects the receiving cavity 10a with the external environment. The housing 10 is also provided with a mounting cavity 10c, at least a portion of which is located on one side of the receiving cavity 10a along the second direction. The mounting cavity 10c is not connected to the air inlet 10b or the receiving cavity 10a. The power supply assembly 12 is located in the mounting cavity 10c.

[0137] It is understandable that the mounting cavity 10c is not connected to the air inlet 10b and the receiving cavity 10a. That is, air from the external environment will not enter the mounting cavity 10c, and the aerosol generated by atomization will not enter the mounting cavity 10c. This increases the reliability of air intake and exhaust. Here, "not connected" means that airflow will not enter the mounting cavity 10c without affecting the electrical connection between the power supply component 12 and the heating structure 111, etc.

[0138] In this embodiment, under the action of suction negative pressure, air from the external environment can enter the receiving cavity 10a through the air inlet 10b and then into the aerosol generating article 20, thereby entraining the aerosol and causing it to flow out through the nozzle 14. The power supply assembly 12 is disposed in the mounting cavity 10c, which reduces the probability of being affected by airflow and increases installation reliability. At the same time, at least a portion of the mounting cavity 10c is disposed on one side of the receiving cavity 10a along the second direction, which allows for a more reasonable layout of the aerosol generating device and reduces the dimensions along the length direction of the aerosol generating article 20.
