[0002] This application claims priority and benefits of patent application number 202311442787.2 filed with the State Intellectual Property Office of China on October 31, 2023, and the entire text of which is incorporated herein by reference. Technical Field

[0003] The present application relates to the field of atomization technology, and more specifically, to an aerosol generating device. Background Art

[0004] An aerosol-generating device is a small device that uses heat-not-burn (HNB) technology to generate aerosols on aerosol-generating products. Currently, many aerosol-generating devices insert a heating element into the aerosol-generating product. The temperature of the heating element is controlled to heat the aerosol-generating product, thereby generating an aerosol for the user to inhale. When the heating element heats the aerosol-generating product, the aerosol-generating matrix inside the aerosol-generating product can adhere to the heating element, making it difficult to remove the aerosol-generating product from the aerosol-generating device.

[0041] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0044] In this application, unless otherwise specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrated; they can be mechanically connected or electrically connected; they can be directly connected or

[0048] Currently, aerosol-generating devices typically include an extraction mechanism, into which the aerosol-generating product is placed and then inserted into a heating element for heating. However, to remove the aerosol-generating product, the entire extraction mechanism must be removed, and then the aerosol-generating product must be removed from the extraction mechanism. This requires two steps, making the operation relatively complex. To address this issue, an embodiment of the present application provides an aerosol-generating device 1000 (shown in Figures 1 and 2).

[0049] Referring to Figures 1, 2, 9, and 16, an aerosol-generating device 100 according to an embodiment of the present application includes a support 10, an extractor 30, and a heating element 50. The support 10 includes a fitting 11. The extractor 30 is movably disposed within the support 10 and includes a clamping member 31. The extractor 30 is used to hold an aerosol-generating article 300. The heating element 50 at least partially extends into the extractor 30 and is inserted into the aerosol-generating article 300 when the aerosol-generating article 300 is loaded in the extractor 30. The heating element 50 is used to heat the aerosol-generating article 300. When the aerosol-generating product 300 is loaded into the extractor 30, the aerosol-generating product 300 drives the extractor 30 to move along the first direction X until the clamping member 31 engages with the mating member 11. The mating member 11 generates a clamping force on the aerosol-generating product 300 through the clamping member 31. When the aerosol-generating product 300 is pulled out of the extractor 30, the clamping force drives the extractor 30 to move along the second direction Y until the clamping member 31 is released from the mating member 11. The first direction X and the second direction Y are opposite.

[0050] Specifically, the aerosol-generating device 100 is a structure capable of generating aerosols by acting on an aerosol-generating substrate through resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound, or mechanical vibration. For example, the aerosol-generating device 100 utilizes microwave radiation to heat the aerosol-generating article 300 to generate an aerosol. Aerosols can be visible or invisible and can include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. The aerosol-generating article 300 is a product loaded with an aerosol-generating substrate. The housing of the aerosol-generating article 300 is not limited to a paper housing, a plastic housing, or a metal housing, and the aerosol-generating substrate is loaded within the housing of the aerosol-generating article 300. The aerosol-generating substrate is a plant leaf product that has been processed and heated to generate an aerosol. The aerosol-generating substrate can be in a fully solid or semi-solid state. When the aerosol-generating matrix is ​​fully solid, it can be produced using processes such as rolling, slurrying, die-casting, and extrusion. The aerosol-generating product 300 can have a cylindrical structure similar to a cigarette, or it can have a sheet, strip, or block structure. In the present application, the aerosol-generating matrix is ​​a solid plant leaf product, and the aerosol-generating product 300 has a cylindrical structure similar to a cigarette.

[0051] Referring to Figures 4 and 11 , the bracket 10 is a structure for accommodating other components. The bracket 10 of the present application is used to accommodate the extractor 30 and enables the extractor 30 to move within the bracket 10. The bracket 10 includes a cover 17, an upper bracket 18, and a lower bracket 19. The cover 17, the upper bracket 18, and the lower bracket 19 together form a receiving space 16, which is used for the extractor 30 to move therein.

[0052] The upper bracket 18 is provided with a mating member 11, which is a structure for cooperating with the clamping member 31 to exert a clamping force on the aerosol-generating product 300. The mating member 11 protrudes from the inner wall 15 of the upper bracket 18 toward the extractor 30. Preferably, the end of the mating member 11 near the cover 17 extends from the inner wall 15 of the upper bracket 18 and gradually increases in thickness along the first direction X, forming an inclined surface at the end of the mating member 11 near the cover 17. This allows the mating member 11 to guide the extractor 30 when the aerosol-generating product 300 moves along the first direction X. The mating member 11 can be integral with the upper bracket 18 or a separate structure. If the mating member 11 is integral with the upper bracket 18, it extends from the inner wall 15 of the upper bracket 18. In this case, the installation of the bracket 10 is relatively simple. When the mating member 11 and the upper bracket 18 are separate structures, the mating member 11 can be detachably or non-detachably mounted on the inner wall 15 of the upper bracket 18. In this case, the processing of the upper bracket 18 is relatively simple. The number of mating members 11 can be one or more, and the number of mating members 11 is the same as the number of clamping members 31.

[0053] The first direction X is the direction in which the aerosol-generating article 300 moves downward to be inserted into the heating element 50 , and the second direction Y is the direction in which the aerosol-generating article 300 is pulled upward to the outside of the aerosol-generating device 100 .

[0054] When the aerosol-generating article 300 is heated by the heating element 50, the aerosol-generating substrate in the aerosol-generating article 300 can easily adhere to the sidewalls of the heating element 50, making it difficult to remove the aerosol-generating article 300 from the aerosol-generating device 100, or even causing the aerosol-generating article 300 to partially break within the aerosol-generating device 100. The extractor 30 of the present application is a structure for carrying the aerosol-generating article 300 and capable of moving with the aerosol-generating article 300. When the aerosol-generating article 300 is heated by the heating element 50, the extractor 300 can generate a clamping force on the aerosol-generating article 300, preventing the aerosol-generating article 300 from easily moving while heated. When the aerosol-generating article 300 is removed, the extractor 300 can support the aerosol-generating article 300 from its bottom. When the aerosol-generating article 300 drives the extractor 30 to move along the second direction Y, the extractor 30 can cause relative movement between the aerosol-generating article 300 and the heating element 50, thereby releasing the adhesion between the aerosol-generating substrate and the heating element 50, and thus allowing the aerosol-generating article 300 to be smoothly removed from the aerosol-generating device 100. For example, when the relative movement distance between the aerosol-generating article 300 and the heating element 50 is 3.5 mm, the aerosol-generating substrate and the heating element 50 are released, and the aerosol-generating article 300 can be smoothly removed from the aerosol-generating device 100. This application does not limit the relative movement distance between the aerosol-generating article 300 and the heating element 50; the relative movement distance between the aerosol-generating article 300 and the heating element 50 can be determined based on the different material properties of the aerosol-generating article 300.

[0055] The clamping member 31 is a structure that cooperates with the mating member 11 to exert a clamping force on the aerosol-generating product 300. In the initial state (as shown in Figures 4 and 11), the clamping member 31 is positioned between the cover 17 and the mating member 11. The clamping member 31 does not engage with the mating member 11. At this point, the aerosol-generating product 300 can smoothly extend into the bottom end of the extractor 30 (as shown in Figures 5 and 12), and the aerosol-generating product 300 is not subjected to a clamping force. Subsequently, the aerosol-generating product 300 is moved in the first direction X by an external force, and the aerosol-generating product 300 can also drive the extractor 30 to move in the first direction X. As a result, the clamping member 31 comes into contact with the mating member 11 (as shown in Figures 6 and 13), and the mating member 11 begins to exert a clamping force on the aerosol-generating product 300 through the clamping member 31. Referring to Figures 3, 10, and 17, the extractor 30 may further include a stopper 35, and the bracket 10 may further include a coupling member 13. The stopper 35 cooperates with the coupling member 13 to limit the maximum distance that the extractor 30 can move in the first direction X. If the aerosol-generating article 300 continues to drive the extractor 30 to move in the first direction X, upon reaching the position where the stopper 35 engages the coupling member 13, the aerosol-generating article 300 and the extractor 30 stop moving in the first direction X (as shown in Figures 7 and 14). At this point, the clamping force exerted by the mating member 11 on the aerosol-generating article 300 through the clamping member 31 reaches its maximum. If the aerosol-generating device 100 is removed in the second direction Y, the clamping force also drives the extractor 30 to move in the second direction Y. At this point, the clamping member 31 moves in the second direction Y to gradually separate from the mating member 11, releasing the engagement (as shown in Figures 8 and 15). When the clamping member 31 and the mating member 11 are completely disengaged, the clamping force disappears, and the aerosol generating product 300 can be smoothly removed from the extractor 30. At this time, since there is still some friction between the aerosol generating product 300 and the inside of the extractor 30, the extractor 30 continues to move along the second direction Y with the aerosol generating product 300. When the extractor 30 moves to a point where it contacts the cover 17, the extractor 30 stops moving, and the aerosol generating substrate is removed from the aerosol generating device 100 (Figures 4 and 11).

[0056] For aerosol-generating products 300 made of different materials, the fit between the clamping member 31 and the mating member 11 can be adjusted to adjust the clamping force on the aerosol-generating product 300. For example, for an aerosol-generating product 300 that easily adheres to the heating element 50, the fit between the clamping member 31 and the mating member 11 can be adjusted to reduce the clamping force on the aerosol-generating product 300, thereby preventing the aerosol-generating product 300 from being separated from the heating element 50. For an aerosol-generating product 300 that is less likely to adhere to the heating element 50, the fit between the clamping member 31 and the mating member 11 can be adjusted to increase the clamping force on the aerosol-generating product 300, thereby clamping the aerosol-generating product 300 and preventing it from separating from the heating element 50 while being heated by the heating element 50.

[0057] The heating element 50 is a structure that generates heat when energized to heat the aerosol-generating article 300, thereby producing an aerosol for inhalation by the user. In one embodiment, the heating element 50 generates heat itself. For example, the heating element 50 may be a resistive heater, an electromagnetic heater, or an infrared heater. After the aerosol-generating article 300 is inserted into the heating element 50, the heating element 50 is energized to generate heat on the surrounding walls of the heating element 50, thereby heating the aerosol-generating matrix within the aerosol-generating article 300. In another embodiment, the heating element 50 can conduct heat to heat the aerosol-generating article 300. For example, the surrounding walls of the heating element 50 may have multiple through-holes, allowing air to flow out of the heating element 50 after external heating to heat the aerosol-generating article 300. The heating element 50 may have a sheet-like or columnar structure. In the present application, the heating element 50 is a columnar structure. If the heating element 50 is a columnar structure, the cross-sectional area of ​​the heating element 50 may be, but is not limited to, circular, triangular, rectangular, or other polygonal. Preferably, the end of the heating element 50 close to the upper bracket 18 may be tapered to facilitate the insertion and removal of the aerosol generating article 300 into and from the heating element 50 .

[0058] In the aerosol-generating device 100 of the present application, when the aerosol-generating product 300 is heated by the heating element 50, the clamping member 31 cooperates with the mating member 11, allowing the extractor 30 to clamp the aerosol-generating product 300. When the aerosol-generating product 300 needs to be removed from the aerosol-generating device 100, the aerosol-generating product 300 can drive the extractor 30 to move together, and the extractor 30 can move the aerosol-generating product 300 relative to the heating element 50, thereby smoothly removing the aerosol-generating product 300 from the aerosol-generating device 100. In the present application, the extractor 30 can be moved by simply inserting or removing the aerosol-generating product 300. Compared to existing aerosol-generating devices 100, the aerosol-generating device 100 of the present application simplifies the operation of removing the aerosol-generating product 300.

[0059] The aerosol generating device 100 will be further described below with reference to the accompanying drawings.

[0060] 3 , 4 , 10 , and 11 , further, in certain embodiments, the extractor 30 further includes an extractor member 33, which is provided with a loading chamber 331, a first opening 333, and a second opening 334. The first opening 333 and the second opening 334 are located at opposite ends of the loading chamber 331 and communicate with the loading chamber 331. The loading chamber 331 is used to load the aerosol-generating product 300. The first opening 333 is used to allow the aerosol-generating product 300 to enter the loading chamber 331, and the second opening 334 is used to allow the heating element 50 to pass through and at least partially extend into the loading chamber 331. The clamping member 31 is connected to the side wall 335 of the extractor member 33. The clamping member 31 is an elastic structure. When the clamping member 31 is not engaged with the mating member 11, the clamping member 31 protrudes toward the outside of the extractor member 33 relative to the side wall 335 of the extractor member 33. When the clamping member 31 is engaged with the mating member 11, the clamping member 31 deforms toward the inside of the loading chamber 331.

[0061] Specifically, the extraction member 33 is a structure for loading the aerosol generating article 300 and capable of moving together with the aerosol generating article 300. Preferably, the material of the extraction member 33 can be a high-temperature resistant plastic, wherein the high-temperature resistant plastic includes but is not limited to polyphenylene sulfide, polyetheretherketone, polyetherketone and polyarylate. The material used in this application is polyetheretherketone, which has the characteristics of high temperature resistance, wear resistance and high mechanical strength. The cross-sectional shape of the extraction member 33 can be, but is not limited to, circular, triangular, rectangular or other polygonal shapes. Preferably, the cross-sectional shape of the extraction member 33 is the same as the cross-sectional shape of the aerosol generating article 300.

[0062] The cross-sectional shape of the loading chamber 331 may be, but is not limited to, circular, triangular, rectangular, or other polygonal shapes. The cross-sectional shape of the first opening 333 may be, but is not limited to, circular, triangular, rectangular, or other polygonal shapes. Preferably, the cross-sectional shape of the loading chamber 331 is the same as the cross-sectional shape of the first opening 333. The cross-sectional area of ​​the first opening 333 is greater than or equal to the cross-sectional area of ​​the loading chamber 331, facilitating the aerosol-generating article 300 to enter the loading chamber 331 through the first opening 333. The cross-sectional area of ​​the loading chamber 331 is the same as or slightly greater than the cross-sectional area of ​​the aerosol-generating article 300, allowing the aerosol-generating article 300 to be smoothly placed into the loading chamber 331. When the clamping member 31 is engaged with the mating member 11, the clamping member 31 on the side wall 335 of the extraction member 33 can exert a strong clamping force on the aerosol-generating article 300. The cross-sectional shape of the second opening 334 may be, but is not limited to, circular, triangular, rectangular, or other polygonal shapes. Preferably, the cross-sectional shape of the second opening 334 is the same as that of the heating element 50. The cross-sectional area of ​​the second opening 334 is equal to or slightly larger than that of the heating element 50, so that the heating element 50 can smoothly extend from the second opening 334 into the loading chamber 331. Furthermore, when the extraction member 33 and the aerosol-generating article 300 are moved along the second direction Y, the inner wall of the second opening 334 can also be used to scrape off portions of the aerosol-generating substrate adhered to the heating element 50, thereby preventing the aerosol-generating substrate from adhering to the heating element 50 and affecting the heating efficiency of the heating element 50.

[0063] The clamping member 31 and the extracting member 33 can be an integral structure or a separate structure. When the clamping member 31 and the extracting member 33 are an integral structure, the clamping member 31 extends from the side wall 335 of the extracting member 33. The material of the clamping member 31 is the same as that of the extracting member 33, and the material of the clamping member 31 can be polyetheretherketone. When the clamping member 31 and the extracting member 33 are separate structures, the clamping member 31 and the extracting member 33 are detachably or non-detachably connected. The clamping member 31 can be made of other high-temperature resistant materials. The number of clamping members 31 can be one or more. When the number of clamping members 31 is one, the clamping member 31 can be connected to any position of the side wall 335 of the extracting member 33. In this case, the number of fitting members 11 is also one, and the position of the fitting member 11 corresponds to the position of the clamping member 31. When the number of clamping members 31 is multiple, the multiple clamping members 31 are evenly or unevenly distributed on the side wall 335 of the extracting member 33. Preferably, the plurality of clamping members 31 are evenly distributed along the sidewall 335 of the extraction member 33, so that when the plurality of clamping members 31 clamp the aerosol-generating article 300, the force applied to each position of the aerosol-generating article 300 is relatively uniform. In this case, the number of mating members 11 is the same as the number of clamping members 31, and the positions of the plurality of mating members 11 correspond to the positions of the plurality of clamping members 31.

[0064] The clamping member 31 in the embodiment of the present application has an elastic structure. When the clamping member 31 is engaged with the mating member 11, the clamping member 31 can deform to clamp the aerosol-generating product 300 in the loading chamber 331. When the clamping member 31 is not engaged with the mating member 11, the clamping member 31 can return to its original shape (the clamping member 31 protrudes relative to the sidewall 335 of the extraction member 33). When the clamping member 31 is not engaged with the mating member 11, the sidewall 335 of the clamping member 31 protrudes relative to the sidewall 335 of the extraction member 33. This allows the clamping member 31 to deform more significantly toward the loading chamber 331 when the clamping member 31 is engaged with the mating member 11, thereby exerting a greater clamping force on the aerosol-generating product 300. In other embodiments, the clamping member 31 may also have a non-elastic structure. For example, the clamping member 31 is a rotatable structure. When the aerosol-generating article 300 and the extraction member 33 are moved into position along the first direction X, the clamping member 31 rotates to cooperate with the mating member 11 to clamp the aerosol-generating article 300. When the aerosol-generating article 300 and the extraction member 33 are moved along the second direction Y, the clamping member 31 rotates back to its original position and is spaced apart from the mating member 11.

[0065] Referring to Figures 3, 10, and 17, in certain embodiments, the sidewall 335 of the extraction member 33 is provided with a through-hole 3351 extending therethrough. The clamping member 31 extends from the inner wall of the through-hole 3351, with at least one side of the clamping member 31 spaced from the corresponding side of the through-hole 3351. The through-hole 3351 provides a space for the clamping member 31 to be mounted therein. Only when at least one side of the clamping member 31 is spaced from the corresponding side of the through-hole 3351 can the clamping member 31 deform when mated with the mating member 11.

[0066] The shape of the perforation 3351 can be, but is not limited to, circular, triangular, rectangular, or other polygonal shapes. The number of perforations 3351 is the same as the number of clamping members 31, and the positions of the perforations 3351 correspond to the positions of the clamping members 31. The shape of the clamping member 31 can be circular, rectangular, or other polygonal shapes. Preferably, the shape of the clamping member 31 corresponds to the shape of the perforation 3351. When the clamping member 31 is rectangular, the shape of the perforation 3351 is also rectangular. In one example, one side of the clamping member 31 is connected to the inner wall of the corresponding side of the perforation 3351, and the other three sides of the clamping member 31 are spaced from the inner wall of the corresponding side of the perforation 3351. In another example, two sides of the clamping member 31 are connected to the inner wall of the corresponding side of the perforation 3351, and the other two sides of the clamping member 31 are spaced from the inner wall of the corresponding side of the perforation 3351. In another example, three sides of the clamp 31 are connected to the inner wall of the corresponding side of the perforation 3351, and the other side of the clamp 31 is spaced from the inner wall of the corresponding side of the perforation 3351. When the clamp 31 is circular, the opening shape of the perforation 3351 is also circular. At this time, the inner wall of the perforation 3351 can be divided into a first arc section, a second arc section, a third arc section and a fourth arc section that are connected in sequence. Similarly, the clamp 31 can also be divided into four sides (four arc sections that are connected in sequence). In one example, one side of the clamp 31 is connected to the inner wall of the corresponding side of the perforation 3351, and the other three sides of the clamp 31 are spaced from the inner wall of the corresponding side of the perforation 3351. In another example, two sides of the clamp 31 are connected to the inner wall of the corresponding side of the perforation 3351, and the other two sides of the clamp 31 are spaced from the inner wall of the corresponding side of the perforation 3351. In another example, three sides of the clamping member 31 are connected to the inner walls of the corresponding sides of the through hole 3351 , and the other side of the clamping member 31 is spaced apart from the inner wall of the corresponding side of the through hole 3351 .

[0067] 3 , 10 , and 17 , in certain embodiments, the clamping member 31 includes a connecting portion 311 and a clamping portion 313 connected to one end of the connecting portion 311. The other end of the connecting portion 311 is connected to the inner wall of the through-hole 3351. In a direction perpendicular to the first direction X, the outer side surface 3131 of the clamping portion 313 protrudes relative to the outer side surface 337 of the extractor 33, and the outer side surface 3131 of the clamping portion 313 protrudes relative to or is flush with the outer side surface of the connecting portion 311. In the first direction X, the clamping portion 313 includes a first sub-clamping portion 315 and a second sub-clamping portion 317 connected to each other. The first sub-clamping portion 315 is closer to the first opening 333 than the second sub-clamping portion 317, and the thickness of the second sub-clamping portion 317 gradually decreases.

[0068] Specifically, the connecting portion 311 is configured to connect the inner wall of the through-hole 3351 with the clamping portion 313. The clamping portion 313 is configured to cooperate with the mating member 11 to generate a clamping force on the aerosol-generating article 300. The outer side surface 3131 of the clamping portion 313 protrudes relative to the outer side surface 337 of the extraction member 33, so that when the clamping portion 313 is mated with the mating member 11, the clamping portion 313 deforms more significantly toward the interior of the loading chamber 331.

[0069] The inner wall of the connecting portion 311 may extend from the inner wall of the extraction member 33. In one embodiment (shown in Figures 3 and 17), the outer side surface 3131 of the clamping portion 313 protrudes relative to the outer side surface of the connecting portion 311. In this embodiment, the material of the connecting portion 311 can be reduced. In another embodiment (shown in Figure 10), the outer side surface 3131 of the clamping portion 313 is flush with the outer side surface of the connecting portion 311. In this embodiment, the processing of the clamping member 31 is relatively simple.

[0070] The second sub-clamping portion 317 extends from the first sub-clamping portion 315 and gradually decreases in thickness, thereby forming an inclined surface on the outer sidewall 335 of the second sub-clamping portion 317. When the extractor 30 moves in the first direction X, the inclined surface of the second sub-clamping portion 317 mates with the inclined surface of the mating element 11, guiding the extractor 30 to continue moving in the first direction X. When the extractor 30 moves in the first direction X, the mating element 11 first mates with the second sub-clamping portion 317. At this point, the clamping force exerted by the mating element 11 and the clamping portion 313 on the aerosol-generating article 300 gradually increases. When the extractor 30 moves to the point where the first sub-clamping portion 315 mates with the mating element 11, the clamping force exerted by the mating element 11 and the clamping portion 313 on the aerosol-generating article 300 reaches its maximum.

[0071] Please refer to Figures 3, 6 and 7. In some embodiments, the first sub-clamping portion 315 includes an inner side surface 3151 and an outer side surface 3153 facing each other, the inner side surface 3151 of the first sub-clamping portion 315 faces the loading chamber 331, the angle between the inner side surface 3151 of the first sub-clamping portion 315 and the first direction X is an acute angle, and the inner side surface 3151 of the first sub-clamping portion 315 is parallel to the outer side surface 3153 of the first sub-clamping portion 315.

[0072] When the first sub-clamping portion 315 is not engaged with the mating member 11, the angle between the inner side surface 3151 of the first sub-clamping portion 315 and the first direction X is an acute angle. For example, the angle between the inner side surface 3151 of the first sub-clamping portion 315 and the first direction X is 5°, 10°, or 15°. Because the inner side surface 3151 of the first sub-clamping portion 315 is parallel to the outer side surface 3153 of the first sub-clamping portion 315, the angle between the outer side surface 3153 of the first sub-clamping portion 315 and the first direction X is the same as the angle between the inner side surface 3151 of the first sub-clamping portion 315 and the first direction X. When the extractor 30 moves so that the outer side surface 3153 of the first sub-clamping portion 315 engages with the mating member 11, the first sub-clamping portion 315 begins to deform toward the loading chamber 331. The angle between the outer side surface 3153 of the first sub-clamping portion 315 and the first direction X begins to decrease, and the angle between the inner side surface 3151 of the first sub-clamping portion 315 and the first direction X also begins to decrease. When the stopper 35 engages with the coupling member 13, the deformation of the first sub-clamping portion 315 reaches its maximum. At this time, the angle between the outer side surface 3153 of the first sub-clamping portion 315 and the first direction X is 0°, and the angle between the inner side surface 3151 of the first sub-clamping portion 315 and the first direction X is also 0°. When the angle between the inner side surface 3151 of the first sub-clamping portion 315 and the first direction X is 0°, the inner side surface 3151 of the first sub-clamping portion 315 is completely in contact with the aerosol generating article 300, so that the aerosol generating article 300 can be clamped over a larger area.

[0073] Referring to Figures 3, 10, and 17, in a first direction X from the first opening 333 to the second opening 334, the through-hole 3351 includes a first inner wall 3353 and a second inner wall 3355 that are opposed to each other, with the first inner wall 3353 being closer to the first opening 333 than the second inner wall 3355. In some embodiments, one side of the clamping member 31 extends from the first inner wall 3353, while the other side of the clamping member 31 is spaced apart from the inner wall of the corresponding side of the through-hole 3351 (as shown in Figures 10 and 17). In other embodiments, one side of the clamping member 31 extends from the second inner wall 3355, while the other side of the clamping member 31 is spaced apart from the inner wall of the corresponding side of the through-hole 3351 (as shown in Figure 3). In other embodiments, the clamping member 31 may also extend from the other inner wall of the through-hole 3351.

[0074] Please refer to Figures 3, 10 and 17. In some embodiments, the extraction member 33 is an integrated structure (Figure 10). In this case, the installation of the extraction member 33 is relatively convenient. In other embodiments, the extraction member 33 includes a first sub-portion 338 and a second sub-portion 339 (Figures 3 and 17), the first sub-portion 338 is connected to the second sub-portion 339, and the clamping member 31 is provided on the first sub-portion 338 and / or the second sub-portion 339. In this case, the materials of the first sub-portion 338 and the second sub-portion 339 may be the same or different. In one example, the materials of the first sub-portion 338 and the second sub-portion 339 are the same, for example, the materials of the first sub-portion 338 and the second sub-portion 339 are both polyetheretherketone. In another example, the materials of the first sub-portion 338 and the second sub-portion 339 are different, for example, the material of the first sub-portion 338 is stainless steel, and the material of the second sub-portion 339 is polyetheretherketone.

[0075] The first sub-section 338 and the second sub-section 339 can be connected by a snap-fit ​​connection. For example, the first sub-section 338 has a snap 3381, and the second sub-section 339 has a groove 3391. The snap 3381 cooperates with the groove 3391 to connect the first sub-section 338 and the second sub-section 339. The first sub-section 338 and the second sub-section 339 can also be connected by an interference fit, gluing, or welding.

[0076] In one example, the clamping member 31 is disposed in the first sub-portion 338, and the clamping member 31 can extend from the first sub-portion 338. The material of the clamping member 31 can be polyetheretherketone or stainless steel. The clamping member 31 can be formed by being recessed from the inner wall of the first sub-portion 338 in a direction away from the extraction member 33 (as shown in Figures 17 and 18), or the clamping member 31 can be extended from the side wall 335 of the first sub-portion 338 (as shown in Figure 3). In another example, the clamping member 31 is disposed in the second sub-portion 339, and the clamping member 31 and the second sub-portion 339 are an integral or split structure. In another example, the clamping member 31 is disposed in the first sub-portion 338 and the second sub-portion 339.

[0077] Please refer to Figures 10 and 17. In some embodiments, the limiting member 35 protrudes from the top wall 336 of the extraction member 33 toward the third direction Z away from the extraction member 33, and the coupling member 13 extends from the inner wall 15 of the upper bracket 18 (Figures 10 and 17). The third direction Z is perpendicular to both the first direction X and the second direction Y. When the extraction member 33 moves along the first direction X, the matching member 11 and the clamping member 31 first cooperate to clamp the aerosol generating product 300, and the coupling member 13 then cooperates with the limiting member 35 to limit the maximum distance that the extraction member 33 moves in the first direction X. Specifically, the limiting member 35 is supported by the coupling member 13 during the movement along the first direction X, so that the extraction member 33 connected to the limiting member 35 can no longer move along the first direction X.

[0078] In one example, there is one limiting member 35. One limiting member 35 can protrude from any position of the top wall 336 of the extractor 33 toward the third direction Z away from the extractor 33. In this case, there is also one coupling member 13, and the position of one coupling member 13 corresponds to the position of the limiting member 35. One limiting member 35 can also protrude from the top wall 336 of the extractor 33 as a whole toward the third direction Z away from the extractor 33 (as shown in Figure 10). In this case, the number of coupling members 13 can be one or more, and the positions of the coupling members 13 can be evenly or unevenly distributed on the inner wall 15 of the upper bracket 18. In another example, there are multiple limiting members 35, and the multiple limiting members 35 are evenly or unevenly distributed on the top wall 336 of the extractor 33. In this case, the number of coupling members 13 is the same as the number of limiting members 35, and the position of the coupling member 13 corresponds to the position of the limiting member 35. Preferably, multiple limit members 35 are evenly distributed on the top wall 336 of the extraction member 33, and multiple coupling members 13 are evenly distributed on the inner wall 15 of the upper bracket 18, so that when the limit members 35 cooperate with the coupling members 13, the force at each position of the extraction member 33 is more uniform.

[0079] Please refer to Figure 3. In other embodiments, the limiting member 35 protrudes from the top wall 336 of the extractor 33 toward the third direction Z away from the extractor 33, and the coupling member 13 is a groove 3391 (shown in Figure 3) provided on the upper bracket 18. The limiting member 35 is supported by the bottom wall of the groove 3391 of the coupling member 13 during the movement along the first direction X, so that the extractor 33 connected to the limiting member 35 can no longer move along the first direction X. In one example, the number of limiting members 35 is one, in which case there is also one coupling member 13, and the position of one coupling member 13 corresponds to the position of the limiting member 35. In another example, there are multiple limiting members 35, and the multiple limiting members 35 are evenly or unevenly distributed on the top wall 336 of the extractor 33. In this case, the number of coupling members 13 is the same as the number of limiting members 35, and the position of the coupling member 13 corresponds to the position of the limiting member 35. Preferably, multiple limit members 35 are evenly distributed on the top wall 336 of the extraction member 33, and multiple coupling members 13 are evenly opened on the inner wall 15 of the upper bracket 18, so that when the limit members 35 cooperate with the coupling members 13, the force at each position of the extraction member 33 is more uniform.

[0080] In other embodiments, when the extractor 33 moves along the first direction X, the bottom wall of the extractor 33 is supported by the bottom wall of the lower bracket 19, so that the extractor 33 cannot continue to move along the first direction X (as shown in Figure 7). In one example, the bottom wall of the extractor 33 cooperates with the bottom wall of the lower bracket 19 to limit the maximum distance that the extractor 33 can move in the first direction X. In another example, the limiter 35 cooperates with the coupling member 13, and the bottom wall of the extractor 33 also cooperates with the bottom wall of the lower bracket 19 to jointly limit the maximum distance that the extractor 33 can move in the first direction X.

[0081] Referring to Figures 3 and 4, in some embodiments, the inner wall 15 of the upper bracket 18 is provided with an extension arm 151, and the matching member 11 extends from the extension arm 151; the aerosol generating device 100 also includes an elastic member 70, which is provided between the extension arm 151 and the top wall 336 of the extraction member 33. When the extractor 30 is not subjected to external force, the elastic member 70 is used to make the extractor 30 contact the bracket 10.

[0082] The elastic member 70 is used to cause the extractor 30 to contact the cover 17 of the bracket 10 when the extractor 30 is not subjected to external forces. The elastic member 70 is also used to help the extractor 30 quickly reach a position of contact with the cover 17 when the extractor 30 moves in the second direction Y. The elastic member 70 can be a coil spring, one end of which is connected to the top wall 336 of the extractor 33 and the other end of which is connected to the inner wall 15 of the upper bracket 18.

[0083] When the extractor 33 is in its initial state (with its top wall 336 in contact with the cover 17), the spring is compressed, forcing the extractor 33 to contact the cover 17 and preventing it from shaking. As the extractor 33 moves in the first direction X, the distance between its top wall 336 and the inner wall 15 of the upper bracket 18 gradually decreases, causing the spring to be more compressed. As the extractor 33 moves in the second direction Y, the spring's inherent elastic potential energy assists in moving the extractor 33 in the second direction Y.

[0084] In the aerosol-generating device 100 of the present application, when the aerosol-generating product 300 is heated by the heating element 50, the clamping member 31 cooperates with the mating member 11, allowing the extractor 30 to clamp the aerosol-generating product 300. When the aerosol-generating product 300 needs to be removed from the aerosol-generating device, the aerosol-generating product 300 can drive the extractor 30 to move together, and the extractor 30 can move the aerosol-generating product 300 relative to the heating element 50, thereby smoothly removing the aerosol-generating product 300 from the aerosol-generating device 100. In the present application, the extractor 30 can be moved by simply inserting or removing the aerosol-generating product 300. Compared to existing aerosol-generating devices 100, the aerosol-generating device 100 of the present application simplifies the operation of removing the aerosol-generating product 300.

[0085] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there are no conflicts in the combination of these technical features, they should be considered to be within the scope of this specification. Furthermore, other implementations can be derived from the above-described embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0086] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
