Description

Technical Field

[0001] This utility model relates to the field of heated non-combustible smokers, and in particular to an aerosol generating device and an aerosol generating system. Background Technology

[0002] Heated tobacco products, also known as aerosol generators, deliver nicotine and flavor compounds to users by heating and atomizing tobacco instead of burning it. The aerosol generators compatible with these devices are mainly divided into two categories based on their structure: one is the traditional structure with an open tail, meaning there is no plug at the front of the smoke-generating section; the other type has a plug at the front of the smoke-generating section. For aerosol generators with a plug, the heating element (such as a heating needle or heating tube) must precisely avoid the plugged area, heating only the smoke-generating section; otherwise, ineffective heating of the area will lead to energy waste, unpleasant odors, or damage to the equipment.

[0003] In existing technologies, the heating depth of aerosol generating devices is mostly fixed. This requires users to equip themselves with different sizes of smoking devices to adapt to the two different types of aerosol-generating products, which is not only cumbersome to operate but also significantly reduces the user experience. Therefore, there is an urgent need for an aerosol generating device that is simple in structure, low in cost, adaptable to different types of aerosol-generating products, and can ensure precise heating of the heating area. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides an aerosol generating device and an aerosol generating system.

[0005] In a first aspect, embodiments of this utility model disclose an aerosol generating device for heating aerosols to generate products, the aerosol generating device comprising:

[0006] A receiving cavity having an open end, wherein the upstream end of the aerosol-generating article is inserted into the receiving cavity from the open end;

[0007] A heating element forms a heating region extending axially along the receiving cavity for heating the aerosol-generating article located within the receiving cavity;

[0008] A press-type position switching component, disposed at the bottom of the receiving cavity, includes a pressing part that receives an aerosol-generating article located in the receiving cavity. The press-type position switching component is configured to cyclically switch between a first position and a second position in response to each pressing operation.

[0009] The first position and the second position are distributed along the axial direction. The first position is closer to the bottom of the receiving cavity than the second position along the axial direction. The bottom of the heating area corresponds to the position of the second position along the axial direction. The pressing operation is to drive the aerosol generating product located in the receiving cavity to press the pressing part.

[0010] By adopting the above technical solution, users can achieve heating of different types of aerosol products by the aerosol generating device without complicated rotation or depth adjustment. It also avoids the risks of energy waste, odor generation and damage to smoking devices caused by ineffective heating areas, ensuring that users have a better user experience.

[0015] A fixing member is fixedly connected to the bottom of the receiving cavity and has a through hole. The through hole is sleeved on the outer periphery of the pressing part and the outer periphery of the rotating part. The side wall of the through hole is provided with at least two first slide rails that match the first slider. A limiting block is provided between adjacent first slide rails.

[0016] In response to the pressing operation, when the pressing part is in the second position, the pressing part moves from the second position along the axial direction, causing the first slider to disengage from the first slide rail and move circumferentially, so that the limiting block and the first slider are aligned along the axial direction, and the elastic element drives the top end of the first slider to engage with the bottom of the limiting block, thereby switching the pressing part to the first position; when the pressing part is in the first position, the movement of the pressing part from the first position along the axial direction causes the first slider to move circumferentially, so that the first slide rail and the first slider are aligned along the axial direction, and the elastic element drives the first slider to engage with the first slide rail, thereby switching the pressing part to the second position.

[0017] Optionally, the pressing part includes a receiving member and a sliding member arranged sequentially along the axial direction, the through hole is sleeved on the outer periphery of the sliding member, and the outer periphery of the receiving member abuts against the side wall of the receiving cavity.

[0018] Optionally, the outer periphery of the slider is disposed on the second slider, and the second slider and the first slide rail are slidably connected.

[0019] Optionally, the sliding disk is made of heat-insulating material.

[0020] Optionally, the elastic modulus of the elastic element is 190~210 GPa.

[0021] Optionally, the sidewall of the receiving cavity is provided with a friction part, the friction part is provided with a friction through hole, the pressing part receives the aerosol generating product passing through the friction through hole along the axial direction, the friction part is located between the receiving cavity and the aerosol generating product, wherein the length of the friction part along the axial direction is less than the length of the heating area along the axial direction.

[0022] Optionally, the friction part is a friction ring or a friction bushing.

[0024] By employing the above technical solution, the press-type position switching component can flexibly adapt to aerosol generation products with and without plugs. After insertion, a light press ensures the heating area precisely aligns with the effective segment of the product, avoiding energy waste and odor generation caused by heating ineffective areas and guaranteeing a pure inhalation experience. Simultaneously, the aerosol generator's scratch-resistant and contamination-resistant structure, along with its stable transmission design, protects the aerosol generation product from damage during insertion and pressing, and prevents impurities from affecting the device's operation. Furthermore, the device requires no complex operation, conforms to user habits, and balances ease of use and stability, providing users with a reliable and efficient aerosol generation experience.

[0039] The following specific embodiments illustrate the implementation of this utility model.

Although the description of this utility model will be presented in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this embodiment. On the contrary, the purpose of describing the utility model in conjunction with the embodiments is to cover other options or modifications that may be derived based on the claims of this utility model. To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0040] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0042] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0044] Firstly, reference Figures 1-11 As shown, an embodiment of this utility model discloses an aerosol generating device 0 for heating aerosols to generate articles. The aerosol generating device 0 includes a receiving cavity 1, a heating element 2, and a press-type position switching assembly 3.

[0045] The receiving cavity 1 has an open end 11, and the upstream end of the aerosol generating article is inserted into the receiving cavity 1 through the open end 11. A heating element 2 is formed along the axial direction of the receiving cavity 1 (e.g., Figure 1 The heating region 21, extending in the direction x shown, is used to heat the aerosol-generated article located in the receiving cavity 1.

[0046] It should be noted that the aerosol generating device 0 in this utility model can be applied to either peripheral heating or internal core heating. For example... Figure 2 and Figure 3 As shown, when the aerosol generating device 0 is an external heating smoke appliance, the heating element 2 is, for example, a heating chamber; for example... Figure 4 and Figure 5 As shown, when the aerosol generating device 0 is an inner core type heating smoke device, the heating element 2 is, for example, a heating needle.

[0047] The press-type position switching component 3 is located at the bottom of the receiving cavity 1 and includes a pressing part 31. The pressing part 31 receives the aerosol generating product located in the receiving cavity, that is, the aerosol generating product abuts against the pressing part 31. Further, the upstream end of the aerosol generating product abuts against the pressing part 31.

[0048] The press-type position switching component 3 is configured to cyclically switch between a first position a and a second position b in response to each press operation. For example, when the press part 31 is in the first position a, a first press operation switches the press part 31 from the first position a to the second position b. A second press operation then switches the press part 31 from the second position b back to the first position a, and so on. Similarly, when the press part 31 is in the second position b, a first press operation switches the press part 31 from the second position b to the first position a. A second press operation then switches the press part 31 from the first position a back to the second position b, and so on.

[0049] The first position a and the second position b are distributed axially, with the first position a being closer to the bottom of the receiving cavity 1 axially than the second position b. Exemplarily, there is a height difference between the first position a and the second position b in the axial direction; further, the second position b is higher than the first position a. The bottom of the heating region 21 corresponds to the axial position of the second position b. Further, axially, the bottom of the heating region 21 is at the same height as the second position b, or the bottom of the heating region 21 is higher than the second position b.

[0050] Those skilled in the art will understand that the plug 01 is located at the front end of the aerosol generating article, that is, at the upstream end of the aerosol generating article. When the pressing part 31 is in the first position a, this means that the plug 01 in the aerosol generating article is far away from the heating area 21, which helps to avoid heating the plug 01.

[0051] The pressing operation involves driving the aerosol generating product located in the receiving cavity 1 to press the pressing part 31. In other words, since the aerosol generating product abuts against the pressing part 31, when the user presses the aerosol generating product located in the receiving cavity 1, the aerosol generating product can be driven to press the pressing part 31.

[0052] Specifically, for example, the initial position of the pressing part 31 is in the second position b, for example Figure 2 and Figure 4 As shown, when a user uses an aerosol generator with a plug 01, they only need to press the aerosol generator once after insertion to drive the pressing part 31 from the initial second position b to the first position a, which is closer to the bottom of the receiving cavity 1, thus completing the installation. Since the bottom of the heating area 21 corresponds to the second position b, when the pressing part 31 moves to the first position a, the entire aerosol generator moves downward relative to the heating area 21, thereby avoiding the plug 01 area of ​​the aerosol generator. This allows the heating energy to be completely concentrated on the tobacco segment or other effective smoke-generating matrix of the aerosol generator, achieving efficient and pure heating, avoiding energy waste, odor generation, and the risk of damage to the smoking device caused by ineffective heating areas, and ensuring that the user obtains a good smoking experience and reliable usage endurance.

[0053] And for example Figure 3 and Figure 5 As shown, when the user uses an aerosol generating product without the plug 01, the user can directly insert the aerosol generating product. If the pressing part 31 is located in the first position a, only one pressing operation is needed to switch from the first position a to the second position b, so that the heating area 21 can correspond to the effective heating section of the aerosol generating product, thereby achieving efficient heating.

[0054] Furthermore, by driving the aerosol generating product to press the pressing part 31, it better suits the user's usage habits, transforming the natural operation of inserting the aerosol generating product into a switching driving force, thus improving the interactive experience. Compared to solutions that use moving parts to drive the aerosol generating product, this invention also eliminates the complex active transmission mechanism, simplifies the structure of the smoking device, avoids energy loss from multiple transmission stages, improves force transmission efficiency, can adapt to aerosol generating products of different diameters, reduces wear on the receiving cavity 1, extends the device's lifespan, and reduces the risk of failure.

[0055] By adopting the above technical solution, users can achieve heating of different types of aerosol products by the aerosol generating device without complicated rotation or depth adjustment. It also avoids the risks of energy waste, odor generation and damage to smoking devices caused by ineffective heating areas, ensuring that users have a better user experience.

[0056] Furthermore, the axial length difference between the first position a and the second position b is configured to correspond to the length of the plug 01 at the front end of the smoke-generating section in the received aerosol-generating product. By precisely matching the axial position difference between the first position a and the second position b with the length of the plug 01, when the pressing part 31 switches between the first position a and the second position b, it can ensure that the smoke-generating section of the aerosol-generating product and the heating area 21 of the heating element 2 are always precisely aligned, avoiding the heating ineffectiveness problem caused by the plug 01 entering the heating area 21. At the same time, it also avoids the aerosol-generating product moving too far, causing some smoke-generating sections to leave the heating area 21, resulting in insufficient heating, insufficient aerosol release, and uneven release concentration, significantly improving heating efficiency, aerosol release stability, and taste consistency.

[0057] In some embodiments of this utility model, reference is made to Figure 1 and Figures 6-9 As shown, the press-type position switching assembly also includes a rotating member 32, an elastic member 33, and a fixing member 34. The rotating member 32 is connected to the pressing part 31, and its outer periphery is provided with a first slider 321 extending axially. The elastic member 33 has one end fixedly connected to the bottom of the receiving cavity 1, and the other end fixedly connected to the rotating member 32. The fixing member 34 is fixedly connected to the bottom of the receiving cavity 1 and has a through hole 341. The through hole 341 is fitted around the outer periphery of the pressing part 31 and the outer periphery of the rotating member 32. The sidewall of the through hole 341 has at least two first slide rails 3411 that match the first slider 321, and a limiting block 3412 is provided between adjacent first slide rails 3411.

[0058] In response to a pressing operation, when the pressing part 31 is in the second position b, the pressing part 31 moves axially from the second position b, causing the first slider 321 to disengage from the first slide rail 3411 and move circumferentially (e.g., along the circumferential direction). Figure 1 The movement in the direction z) causes the limiting block 3412 and the first slider 321 to axially engage. The elastic element 33 drives the top of the first slider 321 to engage with the bottom of the limiting block 3412, causing the pressing part 31 to switch to the first position a. When the pressing part 31 is in the first position a, the axial movement of the pressing part 31 from the first position a drives the first slider 321 to move circumferentially, causing the first slide rail 3411 and the first slider 321 to axially engage. The elastic element 33 drives the first slider 321 to engage with the first slide rail 3411, causing the pressing part 31 to switch to the second position b.

[0059] Specifically, when the pressing part 31 is in the second position b, the aerosol generating product located in the receiving cavity 1 is driven to press the pressing part 31. The pressing part 31 moves from the second position b along the axial direction, thereby driving the rotating part 32 to move synchronously along the axial direction, causing the first slider 321 to disengage from the first slide rail 3411 and rotate circumferentially, so that the limiting block 3412 and the first slider 321 are aligned along the axial direction. The rotating part 32 moves along the axial direction to compress the elastic part 33. The elastic part 33 drives the rotating part 32 to move along the axial direction through elastic action, thereby causing the top end of the first slider 321 to be locked at the bottom of the limiting block 3412, so that the pressing part 31 switches to the first position a.

[0060] When the pressing part 31 is in the first position a, when the aerosol generating product in the receiving cavity 1 presses the pressing part 31, the pressing part 31 moves axially, thereby driving the rotating part 32 to move axially, causing the first slider 321 to separate from the bottom of the limiting block 3412 and rotate circumferentially, so that the first slide rail 3411 and the first slider 321 are axially connected, and the rotating part 32 moves axially to compress the elastic part 33. The elastic part 33 drives the rotating part 32 to move axially through elastic action, thereby driving the first slider 321 to engage with the first slide rail 3411, so that the pressing part 31 switches to the second position b.

[0061] By employing the above technical solution, the cooperation of the first slider 321, the first slide rail 3411, and the limiting block 3412 converts the axial pressing force into the circumferential rotation of the rotating component 32, with the elastic component 33 providing the reset power and final positioning. This ensures that each pressing operation produces a clear and distinct "click" feel, and guarantees that the pressing part 31 can accurately stop at the first position a or the second position b, completely avoiding intermediate states or uncertain positions. This not only achieves the convenience of switching states through pressing, but also ensures the mechanical reliability and long service life of the operation through its internal structure, eliminating the need for any rotation or additional positioning operations by the user, greatly improving the user experience and product durability.

[0062] Further, refer to Figure 10 and Figure 11 As shown, the bottom end of the pressing part 31 is provided with sharp teeth 311. (Refer to reference...) Figures 6-9 As shown, the top of the first slider 321 is provided with a first inclined surface 3211 that slides obliquely with the sharp tooth 311. The bottom of each limiting block 3412 is provided with a second inclined surface 34121 and a third inclined surface 34122 that are distributed circumferentially and slide obliquely with the first inclined surface 3211. The second inclined surface 34121 and the third inclined surface 34122 have the same inclination direction. In the axial direction, the third inclined surface 34122 is closer to the bottom of the receiving cavity 1 than the second inclined surface 34121.

[0063] The tooth 311 has a tip 3111, the second inclined surface 34121 has a first side 341211 and a second side 341212, and a limiting wall 3412102 extending axially is provided between the second side 341212 and the third inclined surface 34122. Axial extension includes a first direction (e.g., Figure 1 The direction shown is x1) and the second direction (e.g. Figure 1 (x2) The first direction is the direction from the second position b to the first position a, and the second direction is the direction from the first position a to the second position b.

[0064] For example, when the pressing part 31 is in the second position b, the first slider 321 engages with the first slide rail 3411, and the tip 3111 of the serration 311 abuts against the first inclined surface 3211. When the aerosol generating product located in the receiving cavity 1 presses the pressing part 31, the pressing part 31 moves along the first direction, thereby driving the rotating member 32 to move synchronously along the first direction, that is, driving the first slider 321 to move along the first slide rail 3411 until the first slider 321 disengages from the first slide rail 3411. At the same time, since the first slider 321 disengages from the first slide rail 3411, the tip 3111 of the serration 311 can move along the first inclined surface 3211, pushing the rotating member 32 to rotate circumferentially relative to the pressing part 31, so that the first inclined surface 3211 and the second inclined surface 34121 are axially aligned, that is, the limiting block 3412 and the first slider 321 are axially aligned. The rotating member 32 moves along the first direction, thereby compressing the elastic member 33. The elastic member 33 drives the rotating member 32 to move along the second direction through elastic action. The first inclined surface 3211 abuts against the second inclined surface 34121, and the first inclined surface 3211 moves along the first side 341211 of the second inclined surface 34121 to the second side 341212 where it is limited by the limiting wall 3412102. That is, the top of the first slider 321 is stuck at the bottom of the limiting block 3412, so that the pressing part 31 switches to the first position a.

[0065] When the aerosol generating product located in the receiving cavity 1 is driven to press the pressing part 31 again, the pressing part 31 moves along the first direction, and the tip 3111 of the sharp tooth 311 abuts against the first inclined surface 3211, thereby driving the rotating part 32 to move along the first direction, that is, the first slider 321 moves along the limiting wall 3412102. When the first slider 321 separates from the limiting wall 3412102 (that is, the first slider 321 separates from the bottom of the limiting block 3412), the tip 3111 of the sharp tooth 311 can move along the first inclined surface 3211. Then the first inclined surface 3211 can move along the third inclined surface 34122, pushing the rotating part 32 to rotate circumferentially relative to the pressing part 31, until the first slide rail 3411 and the first slider 321 are axially connected. The rotating member 32 moves along the first direction, thereby compressing the elastic member 33. The elastic member 33 drives the rotating member 32 to move along the second direction through elastic action, thereby driving the first slider 321 to engage with the first slide rail 3411, so that the pressing part 31 switches to the second position b.

[0066] By employing the above technical solution, the precise oblique sliding engagement of the pointed teeth 311 with the first inclined surface 3211, and the second inclined surface 34121 with the third inclined surface 34122, not only can the directional rotation of the rotating part 32 be achieved without additional circumferential operation, ensuring the automation and convenience of switching the position of the pressing part 31, but also ensures precise docking of the first slider 321 with the limiting block 3412 and the first slide rail 3411, avoiding misalignment and jamming. Furthermore, the inclined surface structure significantly reduces component contact friction and operational resistance, resulting in a smoother and less strenuous pressing experience for the user, effectively preventing aerosol-generated products from bending due to improper force. Simultaneously, it evenly distributes force, reduces stress concentration, extends component lifespan, and the overall structure is compact, facilitating miniaturization.

[0067] In some embodiments of this utility model, reference is made to Figure 1 and Figure 11 As shown, the pressing part 31 includes a receiving member 312 and a sliding member 313 arranged sequentially along the axial direction. The through hole 341 is sleeved on the outer periphery of the sliding member 313, and the outer periphery of the receiving member 312 abuts against the side wall of the receiving cavity 1.

[0068] In the above embodiments, the large-area receiving component 312 provides a wide and stable receiving surface for the aerosol-generated product, ensuring uniform force distribution during insertion and pressing, and preventing damage to the aerosol-generated product due to excessive local stress. Simultaneously, the outer periphery of the receiving component 312 abuts against the side wall of the receiving cavity 1, ensuring that the pressing part 31 can move precisely linearly along the axis of the receiving cavity 1 in response to the pressing operation, avoiding radial swaying or deflection during movement, and ensuring the reliability and consistency of the pressing part 31's position switching. During use, the aerosol-generated product may produce debris or condensate; the close abutment between the receiving component 312 and the side wall of the receiving cavity 1 constitutes an effective physical anti-contamination barrier. This barrier effectively prevents foreign objects from entering the bottom of the receiving cavity 1 through the gap between the outer periphery of the pressing part 31 and the side wall of the receiving cavity 1, and then into the interior of the pressing position switching component 3 (such as the aforementioned connecting structures like the sharp teeth 311, the first slider 321, and the first slide rail 3411) or the power supply component, thereby preventing operational jamming or electrical malfunctions caused by contamination. Furthermore, when the pressing part 31 reciprocates axially, the receiving member 312 slides relative to the receiving cavity 1. During this sliding process, the continuous contact between the receiving member 312 and the side wall of the receiving cavity 1 naturally scrapes away impurities such as soot and condensate adhering to the side wall of the receiving cavity 1. This self-cleaning effect helps remove residues adhering to the receiving cavity 1 without requiring the user to disassemble the device, significantly reducing the difficulty of maintenance after use.

[0069] Furthermore, the receiving component 312 is made of a heat-insulating material, such as PEEK material. As the component that directly receives the aerosol-generating product, the receiving component 312 will inevitably come into contact with heat from the heating zone 21. Using a heat-insulating material for the receiving component 312 can effectively prevent heat transfer from the aerosol-generating product to the pressing part 31 and the bottom of the aerosol generating device 0, reducing heat dissipation to unnecessary areas, and allowing the heating energy to be more concentrated on the effective smoke-generating section of the aerosol-generating product, thereby improving energy utilization efficiency.

[0070] Further, continue to refer to Figure 4 and Figure 5 As shown, when the aerosol generating device 0 is an inner core type heating device, the press-type position switching component 3 is sleeved on the outer periphery of the heating element 2, that is, the pressing part 31, the rotating part 32, the fixing part 34 and the elastic part 33 are respectively sleeved on the outer periphery of the heating element 2, and the heating element 2 is inserted into the aerosol generating product through the elastic part 33, the fixing part 34, the rotating part 32 and the pressing part 31 for heating.

[0071] In some embodiments of this utility model, the outer periphery of the slider 313 is disposed on the second slider (not shown), and the second slider (not shown) and the first slide rail 3411 are slidably connected. By sliding the second slider (not shown) and the first slide rail 3411, the radial wobbling and deflection commonly seen during the pressing process can be effectively eliminated, and the risk of movement jamming is greatly reduced, making the pressing action extremely smooth. The user can complete the operation without applying additional impact force or adjusting the pressing angle, fundamentally avoiding accidental damage to the aerosol-generating product caused by poor operation, such as causing the aerosol-generating product to bend, crush, or break at the end.

[0072] In some embodiments of this invention, the elastic modulus of the elastic element 33 is 190~210 GPa. This range of elastic modulus ensures a smoother pressing process when the aerosol-generating product located in the receiving cavity 1 presses against the pressing part 31, preventing excessive pressure that could deform or damage the aerosol-generating product. Simultaneously, within this elastic modulus range, the elastic element 33 provides just the right amount of elastic force, precisely shifting the position of the pressing part 31 without repeated pressing and adjustment, thus reducing frictional damage to the aerosol-generating product within the receiving cavity 1.

[0073] In some embodiments provided by this utility model, the side wall of the receiving cavity 1 is provided with a friction part, the friction part is provided with a friction through hole, the pressing part 31 receives the aerosol generating product passing through the friction through hole along the axial direction, the friction part is located between the receiving cavity 1 and the aerosol generating product, wherein the axial length of the friction part is less than the axial length of the heating area 21.

[0074] In the above embodiment, during the axial movement of the aerosol generating article relative to the receiving cavity 1, it is displaced relative to the friction part, rather than relative to the sidewall of the receiving cavity 1. Along the axial direction, due to the presence of the press-type position switching component 3, the length of the contact portion between the aerosol generating article and the sidewall of the receiving cavity 1 is less than the length of the sidewall of the receiving cavity 1, but greater than or equal to the length of the heating area 21. Because the length of the contact portion between the friction part and the aerosol generating article is less than the length of the heating area 21, i.e., the axial length of the friction part in this embodiment is smaller, the contact area between the friction part and the aerosol generating article is smaller, resulting in less frictional resistance between them. This avoids the large frictional resistance generated by large-area contact between the friction part and the sidewall of the receiving cavity, ensuring small and stable frictional resistance between the aerosol generating article and the sidewall of the receiving cavity 1, resulting in smoother operation.

[0075] Furthermore, the friction part is a friction ring or friction bushing, which, while ensuring the smooth insertion and pressing of the sol-generated product, further reduces wear, extends service life, and improves the overall reliability of the device.

[0076] Secondly, embodiments of this utility model disclose an aerosol generation system, including an aerosol generation device and an aerosol generation article as described in any embodiment of the first aspect.

[0077] By employing the above technical solution, the press-type position switching component 3 can flexibly adapt to aerosol generation products with and without plugs 01. After insertion, a light press allows the heating area 21 to precisely align with the effective segment of the product, avoiding energy waste and odor generation caused by heating ineffective areas and ensuring a pure inhalation experience. Simultaneously, the aerosol generation device's scratch-resistant and contamination-resistant structure, along with its stable transmission design, protects the aerosol generation product from damage during insertion and pressing, and prevents impurities from affecting the device's operation. Furthermore, it requires no complex operation, conforms to user habits, and balances ease of use and stability, providing users with a reliable and efficient aerosol generation experience.

Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
