An installation cavity 1130 is formed between the frame 112 and the base 113, and the installation cavity 1130 can be used to accommodate components such as the drive assembly 14, the main control board 15, and the battery. The base 113 and the frame 112 can be connected together in a detachable manner to facilitate the maintenance, replacement or upgrading of the parts in the installation cavity 1130. Of course, the base 113 and the frame 112 can also be connected together in a non-detachable manner to prevent the user from accidentally opening the installation cavity 1130 and causing damage to the parts.

The frame 112 may be recessed on one side of the cassette seat 211 to form a mounting cavity 1121 for accommodating the mounting seat 122. One end of the heater 121 is inserted into the mounting seat 122 and fixed in the mounting cavity 1121 via the mounting seat 122. The other end of the heater 121 may pass through the cassette seat 211 to heat the medium conveying belt 22 in the cassette seat 211.

A receiving cavity 1120 for receiving the aerosol generating product 20 is formed between the cover 111 and the frame 112. The cover 111 and the frame 112 can be connected together by one or more detachable methods such as snap connection, threaded connection, magnetic connection, etc., so that the aerosol generating product 20 can be taken out and replaced by opening the cover 111. In this embodiment, at least one magnet 114 is embedded on the side of the cover 111 facing the frame 112, and at least one magnet 115 is embedded on the side of the frame 112 facing the cover 111 corresponding to the at least one magnet 114, so that the cover 111 and the frame 112 are magnetically fixed to each other through the magnets 114 and 115.

In some embodiments, the cover 111 may be formed entirely or at least partially of a transparent material. The term "transparent" is used to describe a material that allows at least a significant portion of incident light to pass through it, allowing for seeing through the material. In the present invention, a substantially transparent material may allow enough light to pass through it so that the media transport belt 22 within the cover 111 is visible.

The cover 111 may be completely transparent; alternatively, the cover 111 may have a lower level of transparency while still transmitting enough light to allow the media conveyor belt 22 within the cover 111 to be visible. Further, the cover 111 may include one or more areas formed of a transparent material so that a portion of the media conveyor belt 22 is visible through the one or more areas. In addition, the area formed of the transparent material may be colored, tinted, or colorless. Of course, in other embodiments, the cover 111 may also be made of an opaque material.

As shown in FIGS. 12-17 , the aerosol generating product 20 includes a box seat 211, one side of the box seat 211 is open to form a cavity 210, and the cover body 111 is disposed on the open mouth of the cavity 210 to seal the cavity 210. Of course, in other embodiments, the aerosol generating product 20 may further include a box cover disposed on the box seat 211, and the open mouth of the cavity 210 is sealed by the box cover.

The storage tray 23 and the receiving tray 24 are rotatably disposed on the cassette seat 211, respectively. The storage tray 23 can rotate in a preset direction to unwind the medium conveying belt 22, and the receiving tray 24 can rotate in a direction that is the same as or opposite to the preset direction to rewind the medium conveying belt 22. In this embodiment, the storage tray 23 is configured to rotate in a clockwise direction (or in a counterclockwise direction in other embodiments) to unwind the medium conveying belt 22, and the receiving tray 24 is configured to rotate in a clockwise direction (or in a counterclockwise direction in other embodiments) to rewind the medium conveying belt 22.

In some embodiments, one of the storage tray 23 and the receiving tray 24 is a driving wheel, and the other is a driven wheel. In this embodiment, the receiving tray 24 is a driving wheel and is connected to the output shaft 142, and the storage tray 23 is a driven wheel. The receiving tray 24 rotates under the drive of the output shaft 142 to reel in the medium conveying belt 22, thereby driving the storage tray 23 to rotate synchronously to unwind the medium conveying belt 22. In other embodiments, the storage tray 23 and the receiving tray 24 can also be driving wheels, and can be connected to the driving assembly 14 respectively. In other embodiments, the storage tray 23 and the receiving tray 24 can also rotate asynchronously. For example, the storage tray 23 first unwinds a section of the medium conveying belt 22, and after heating is completed, the receiving tray 24 is driven to rotate for rewinding.

The medium conveyor belt 22 may include a belt-shaped base belt 221 and a matrix layer 222 disposed on the base belt 221. The matrix layer 222 includes an atomizing medium, which may include one or more of a solid and a gel, and is used to generate an aerosol after heating. The base belt 221 is used to carry the matrix layer 222.

The base belt 221 has a first surface 2211 and a second surface 2212 that are arranged opposite to each other in the thickness direction. When the medium conveying belt 22 is wound on the storage disk 23 and the receiving disk 24, the second surface 2212 of the base belt 221 may face the center line of the storage disk 23 and the receiving disk 24, and the first surface 2211 of the base belt 221 is relatively far away from the center line of the storage disk 23 and the receiving disk 24. The matrix layer 222 may be arranged on the first surface 2211 and/or the second surface 2212 of the base belt 221 by coating, lamination or bonding. In addition, the matrix layer 222 may be distributed continuously on the base belt 221, or may be distributed at intervals in different regions.

Specifically, in this embodiment, the matrix layer 222 is disposed on the first surface 2211 of the base tape 221. Of course, in other embodiments, the matrix layer 222 may also be disposed on the second surface 2212 of the base tape 221, or disposed on both the first surface 2211 and the second surface 2212 of the base tape 221.

Furthermore, the base belt 221 may be made of a heat-conducting material, such as a heat-conducting metal material such as aluminum foil or copper foil. Of course, the base belt 221 may also be made of a heat-conducting non-metallic material, such as graphite. In other embodiments, the medium conveyor belt 22 may also be made entirely of the matrix layer 222, that is, the medium conveyor belt 22 does not include the base belt 221.

The heater 121 can be in contact with the side of the medium conveyor belt 22 where the matrix layer 222 is not provided, and transfer heat to the matrix layer 222 through the base belt 221. In this way, it is possible to prevent the heated matrix layer 222 from adhering to the heater 121, thereby affecting the heating effect of the heater 121. Of course, in other embodiments, the heater 121 can also be in direct contact with the matrix layer 222, which is conducive to improving the heat transfer efficiency and reducing the heat loss. In this case, the medium conveyor belt 22 does not need to be made of a heat-conducting material.

In some embodiments, the bottom wall of the cavity 210 may also protrude to form a partition 214 and a partition 215, and the inner wall surfaces of the partition 214 and the partition 215 respectively define a first receiving space 2140 and a second receiving space 2150, and the storage disk 23 and the receiving disk 24 are rotatably disposed in the first receiving space 2140 and the second receiving space 2150. One side of the first receiving space 2140 has an outlet 2141, and one side of the second receiving space 2150 has an inlet 2151, and the medium conveying belt 22 wound on the storage disk 23 can pass through the outlet 2141 and be rolled up on the receiving disk 24 through the inlet 2151.

The parts of the medium conveyor belt 22 before and after atomization are respectively contained in the first containing space 2140 and the second containing space 2150. Since the matrix layer 222 usually becomes more fluffy after atomization, the thickness of the medium conveyor belt 22 becomes larger. In order to better utilize the space in the cavity 210, the diameter of the second containing space 2150 can be designed to be larger than the diameter of the first containing space 2140. Of course, in other embodiments, without considering the spatial size of the cavity 210, the diameter of the second containing space 2150 can also be less than or equal to the diameter of the first containing space 2140.

In this embodiment, the partition 214 and the partition 215 are respectively in the shape of an arc with one side open, and the partition 214 and the partition 215 are connected to form an S-shaped structure, and the partition 214 is located at the lower side of the partition 215. Of course, in other embodiments, the structures of the partition 214 and the partition 215 can also be deformed in other ways, for example, the partition 214 and the partition 215 can also be not connected together, and for another example, the partition 214 and/or the partition 215 can also be in other shapes such as an ellipse or a square. Of course, in other embodiments, the partition 214 and the partition 215 can also be arranged side by side in the horizontal direction, or can also be inclined at a certain angle to the horizontal direction or the vertical direction.

The storage disk 23 may include a storage reel 233 and a storage base 231 and a storage disk cover 232 respectively disposed at both ends of the storage reel 233. The unheated portion of the medium conveying belt 22 may be wound on the storage reel 233, and the storage base 231 and the storage disk cover 232 may limit the floating space of the medium conveying belt 22 in the axial direction of the storage reel 233 to prevent the medium conveying belt 22 from coming out during the winding process.

In this embodiment, the storage chassis 231 and the storage disk cover 232 are both in the shape of a disk, and the storage reel 233 is in the shape of a cylinder and is coaxially arranged with the storage chassis 231 and the storage disk cover 232, so that the medium conveying belt 22 wound on the storage reel 233 can also be in the shape of a cylinder. Of course, in other embodiments, the storage reel 233 can also be in other shapes such as an ellipse or a square. The shape of the radial cross section of the storage chassis 231 and the storage disk cover 232 can match (be the same as or similar to) the shape of the radial cross section of the storage reel 233, or can also not match (be different from or different from) the shape of the radial cross section of the storage reel 233.

In some embodiments, the storage reel 233 may include a shaft segment 2331 integrally formed with the storage chassis 231 and a shaft segment 2332 integrally formed with the storage disc cover 232, and the shaft segments 2331 and 2332 are mutually sleeved to form the storage reel 233. In other embodiments, the storage reel 233 may also be formed by only extending the storage chassis 231 or the storage disc cover 232, or the storage reel 233 may also be a separately formed component.

In some embodiments, the distance L1 between the storage chassis 231 and the storage tray cover 232 is greater than the width W of the medium conveying belt 22, so that the medium conveying belt 22 does not generate friction with the storage chassis 231 and the storage tray cover 232, so that the medium conveying belt 22 can move smoothly without getting stuck. Here, the distance L1 between the storage chassis 231 and the storage tray cover 232 refers to the vertical distance between the side of the storage chassis 231 facing the storage tray cover 232 and the side of the storage tray cover 232 facing the storage chassis 231.

It can be understood that in other embodiments, the distance L1 between the storage chassis 231 and the storage disc cover 232 may also be equal to the width W of the medium conveying belt 22. In other embodiments, the storage reel 233 may be provided with the storage chassis 231 or the storage disc cover 232 at only one end, and the other end of the medium conveying belt 22 may be limited by the cover 111 or the cassette seat 211. Of course, in other embodiments, the storage reel 233 may not be provided with the storage chassis 231 and the storage disc cover 232 at both ends.

Similarly, the storage tray 24 may also include a storage reel 243 and a storage bottom plate 241 and a storage tray cover 242 respectively disposed at both ends of the storage reel 243. The heated portion of the medium conveying belt 22 may be wound on the storage reel 243, and the storage bottom plate 241 and the storage tray cover 242 may limit the floating space of the medium conveying belt 22 in the axial direction of the storage reel 243 to prevent the medium conveying belt 22 from coming out during the winding process.

In this embodiment, the storage chassis 241 and the storage tray cover 242 are both in the shape of a disk, and the storage reel 243 is in the shape of a cylinder and is coaxially arranged with the storage chassis 241 and the storage tray cover 242, so that the medium conveying belt 22 wound on the storage reel 243 can also be in the shape of a cylinder. Of course, in other embodiments, the storage reel 243 can also be in other shapes such as an ellipse or a square. The shape of the radial cross section of the storage chassis 241 and the storage tray cover 242 can match (be the same as or similar to) the shape of the radial cross section of the storage reel 243, or can also not match (be different from or different from) the shape of the radial cross section of the storage reel 243.

In some embodiments, the storage reel 243 may include a shaft segment 2431 integrally formed with the storage chassis 241 and a shaft segment 2432 integrally formed with the storage tray cover 242, and the shaft segments 2431 and 2432 are mutually sleeved to form the storage reel 243. In other embodiments, the storage reel 243 may also be formed by only extending the storage chassis 241 or the storage tray cover 242, or the storage reel 243 may also be a separately formed component.

In some embodiments, the distance L2 between the storage chassis 241 and the storage tray cover 242 is greater than the width W of the medium conveying belt 22, so that the medium conveying belt 22 does not generate friction with the storage chassis 241 and the storage tray cover 242, so that the medium conveying belt 22 can move smoothly without getting stuck. Here, the distance L2 between the storage chassis 241 and the storage tray cover 242 refers to the vertical distance between the side of the storage chassis 241 facing the storage tray cover 242 and the side of the storage tray cover 242 facing the storage chassis 241.

It can be understood that in other embodiments, the distance L2 between the storage chassis 241 and the storage tray cover 242 may also be equal to the width W of the medium conveying belt 22. In other embodiments, the storage reel 243 may also be provided with the storage chassis 241 or the storage tray cover 242 at only one end, and the other end of the medium conveying belt 22 may be limited by the cover body 111 or the box seat 211. Of course, in other embodiments, the storage reel 243 may not be provided with the storage chassis 241 and the storage tray cover 242 at both ends.

During assembly, the storage chassis 231 can be first installed on the box seat 211, and the storage chassis 231 can rotate smoothly on the box seat 211, then the medium conveying belt 22 is stored in the storage tray 23 in a winding manner, and finally the storage tray cover 232 is covered. Similarly, the storage chassis 241 is installed on the box seat 211, and the storage chassis 241 can rotate smoothly on the box seat 211, then the medium conveying belt 22 is stored in the storage tray 24 in a winding manner, and finally the storage tray cover 242 is covered.

The output shaft 142 can pass through the box seat 211 and be plugged into the storage reel 243 of the storage tray 24. The storage reel 243 is formed with a socket 2430 for the output shaft 142 to be inserted. The radial cross-section of the socket 2430 and the output shaft 142 can be a non-circular shape such as a D-shape, a quadrilateral, a polygon, an ellipse, etc., so that the output shaft 142 can be circumferentially fixed in the socket 2430, so that the reducer 141 can drive the storage tray 24 to rotate, and the plug-in matching method makes it easy to disassemble and assemble the aerosol generating product 20 and the aerosol generating device 10. Of course, in other embodiments, the output shaft 142 can also be connected to the storage tray 24 in other ways, such as threaded connection, pin connection, etc.

In some embodiments, the aerosol generating system 100 may further include a damper 17 connected to the storage disk 23, which is used to provide a reverse force to keep the storage disk 23 in a tensioned state to prevent the medium conveying belt 22 from loosening. The damper 17 may be disposed in the cartridge seat 211 or in the body 11. In this embodiment, the damper 17 is disposed in the body 11, so that it can be reused, reducing the replacement cost.

In this embodiment, the damper 17 is a damping wheel 170 and is coaxially arranged with the storage disk 23. The physical properties of the damping wheel 170 itself will keep the storage disk 23 in a tensioned state. The damping wheel 170 can provide a damping torque that is opposite to the preset rotation direction of the storage disk 23 (counterclockwise in this embodiment). When the medium conveying belt 22 is not moving, the damping torque of the damping wheel 170 can tighten the storage disk 23 to prevent the medium conveying belt 22 from loosening. When the medium conveying belt 22 moves, the damping torque of the damping wheel 170 can make the medium conveying belt 22 subject to a certain resistance during the movement, so that the medium conveying belt 22 can achieve a pre-tightening effect during the movement.

Here, the damping torque of the damping wheel 170 satisfies: the torque of the reducer 141 = safety factor * damping torque * (D1/D2) / transmission efficiency of the reducer 141, where D1 is the diameter of the portion of the medium conveying belt 22 wound on the receiving tray 24, and D2 is the diameter of the portion of the medium conveying belt 22 wound on the storage tray 23. Of course, in other embodiments, the damper 17 may also adopt other known structures capable of providing damping torque, such as a spring, a torsion spring, etc.

One end of the damping wheel 170 has a damping shaft 171, which can pass through the box seat 211 and be plugged into the storage reel 233 of the storage disk 23. The damping wheel 170 can use damping grease as a damping medium, and use the viscosity of the damping grease to hinder the movement of the damping shaft 171, so as to obtain a damping effect. A plug-in hole 2330 for inserting the damping shaft 171 is formed on the storage reel 233. The radial cross-section of the plug-in hole 2330 and the damping shaft 171 can be a non-circular shape such as a D-shape, a quadrilateral, a polygon, or an ellipse, so that the damping shaft 171 can be circumferentially fixed in the plug-in hole 2330 to prevent the damping shaft 171 from rotating in the plug-in hole 2330. The plug-in matching method makes it easy to assemble and disassemble the damping wheel 170 and the storage disk 23. Of course, in other embodiments, the damping wheel 170 can also be connected to the storage disk 23 by other methods, such as riveting, pinning, threaded connection, etc.

In some embodiments, the aerosol generating article 20 may further include an atomizing seat 25, in which an atomizing chamber 250 is formed, and an inlet 251 and an outlet 252 are formed on the side wall of the atomizing seat 25, which are connected to the atomizing chamber 250. The medium conveying belt 22 can enter the atomizing chamber 250 through the inlet 251, and after being heated and atomized in the atomizing chamber 250, it can be transmitted through the outlet 252. One end of the heater 121 can extend into the atomizing chamber 250 to heat the medium conveying belt 22 entering the atomizing chamber 250.

In some embodiments, the atomizer seat 25 can be installed together with the box seat 211 in a detachable manner, and the atomizer seat 25 can be reused to reduce replacement costs. Of course, in its embodiments, the atomizer seat 25 can also be installed together with the box seat 211 in a non-detachable manner, or the atomizer seat 25 can also be integrally formed with the box seat 211.

In some embodiments, an air inlet 2110 for allowing external air to enter the atomizing chamber 250 may be provided on the side wall of the cartridge seat 211. Specifically, the air inlet 2110 may be connected to the receiving chamber 210, and then connected to the atomizing chamber 250 through the receiving chamber 210.

In some embodiments, the cross-section of the inlet 251 and the outlet 252 (here, the cross-section perpendicular to the direction of travel of the medium conveyor belt 22) may be the same or similar to the cross-section of the medium conveyor belt 22 (here, the cross-section perpendicular to the direction of travel of the medium conveyor belt 22). In addition, a clearance fit may be adopted between the inlet 251, the outlet 252 and the medium conveyor belt 22, so that the medium conveyor belt 22 can move smoothly without getting stuck, and the edges of the inlet 251 and the outlet 252 can be prevented from scratching the medium conveyor belt 22. In addition, the annular gap 2510 formed between the periphery of the inlet 251 and the medium conveyor belt 22 and/or the annular gap 2520 formed between the periphery of the outlet 252 and the medium conveyor belt 22 can also be used as an airflow channel to connect the atomization chamber 250 with the containing chamber 210, and then connect with the air inlet 2110.

It is understandable that the size of the annular gap 2510 and the annular gap 2520 should not be too small, otherwise it may cause excessive suction resistance, resulting in too low pressure in the atomizing chamber 250 and causing suction turbulence, affecting the suction experience. Of course, the size of the annular gap 2510 and the annular gap 2520 should not be too large, reducing or avoiding the leakage of the aerosol generated in the atomizing chamber 250 through the inlet 251 and the outlet 252.

Specifically, in this embodiment, the atomizer seat 25 is disposed on the upper side of the cartridge seat 211, and may include a main body 254 and an extension portion 255 extending upward from the main body 254. An air outlet channel 253 communicating with the atomizer chamber 250 is formed in the extension portion 255, and the lower end of the nozzle 30 may be inserted into the air outlet channel 253. The main body 254 may be accommodated on the upper side of the cavity 210, the atomizer chamber 250 is formed in the main body 254, and the inlet 251 and the outlet 252 are respectively formed on two opposite sides of the atomizer seat 25 in the transverse direction.

Of course, in other embodiments, the atomizer seat 25 may also be disposed at other positions of the cartridge seat 211. In addition, the configuration of the inlet 251 and the outlet 252 is not limited, for example, the inlet 251 and the outlet 252 may be disposed at the same side of the atomizer seat 25; or, the inlet 251 may be disposed at one lateral side of the atomizer seat 25, and the outlet 252 may be disposed at the bottom side of the atomizer seat 25.

In some embodiments, the aerosol generating article 20 may further include a guide structure 28, which is disposed in the cavity 210 and is used to guide the medium conveyor belt 22 during its travel, to ensure smooth transmission of the medium conveyor belt 22, and to ensure good contact between the medium conveyor belt 22 and the heater 121. In some embodiments, there may be multiple guide structures 28, which are spaced apart on the transmission path of the medium conveyor belt 22. In this embodiment, the guide structure 28 is a limiting roller 280, and the rolling friction of the limiting roller 280 ensures smooth transmission of the medium conveyor belt 22. Of course, in other embodiments, the guide structure 28 may also be other structures such as convex ribs and convex columns.

Each guide structure 28 may include two spaced apart limiting steps 2851 and 2852, which can allow the medium conveying belt 22 to be always limited in the axial space between the limiting steps 2851 and 2852. In some embodiments, the distance L3 between the limiting steps 2851 and 2852 may be greater than the width W of the medium conveying belt 22, so that the medium conveying belt 22 has a certain floating space in the axial direction of the limiting roller 280, so that the medium conveying belt 22 does not generate friction with the limiting steps 2851 and 2852, thereby ensuring the smooth transmission of the medium conveying belt 22 and avoiding jamming. Of course, in other embodiments, the distance L3 between the limiting steps 2851 and 2852 may also be equal to the width W of the medium conveying belt 22, so that the movement of the medium conveying belt 22 is more stable.

Specifically, in this embodiment, the limiting roller 280 includes a roller shaft 286 and a roller sleeve 285 rotatably sleeved on the roller shaft 286. The roller shaft 286 is mounted on the cassette seat 211, and the outer surface of the roller sleeve 285 is used to contact with the medium conveying belt 22 and generate rolling friction. The limiting steps 2851 and 2852 are respectively formed by the axial ends of the roller sleeve 285 protruding radially outward. In other embodiments, the roller shaft 286 can also be integrally formed with the cassette seat 211.

In some embodiments, the plurality of guide structures 28 may include guide structures 281, 282, and 283 that are sequentially distributed on the transmission path of the medium conveyor belt 22. The medium conveyor belt 22 to be heated sequentially passes through the guide structures 281, 282, and the inlet 251 to enter the atomizing chamber 250 for atomization, and the atomized medium conveyor belt 22 is output from the outlet 252 and then guided by the guide structure 283, and then rolled up on the storage tray 24.

The guide structure 281 is disposed near the outlet 2141, so that the medium conveying belt 22 wound on the storage disk 23 can be smoothly conveyed, and the transmission of the medium conveying belt 22 is not affected by the change in the size of the medium conveying belt 22 wound on the storage disk 23. The guide structure 282 and the guide structure 283 are respectively disposed on two opposite sides of the atomizing seat 25 in the lateral direction, so as to make the medium conveying belt 22 in good contact with the heater 121. It should be noted that the guide structure 282 and the guide structure 283 are respectively disposed corresponding to the inlet 251 and the outlet 252. When the setting positions of the inlet 251 and the outlet 252 are changed, the setting positions of the guide structure 282 and the guide structure 283 can be changed accordingly.

The relative positions among the guide structure 282, the guide structure 283, and the heater 121 are configured such that the positioning surface P2 formed by the guide structure 282 and the guide structure 283 on the medium conveyor belt 22 is not on the same plane as the plane P1 where the heating surface 1211 of the heater 121 is located, and the medium conveyor belt 22 can be pressed toward the heating surface 1211 so as to be in close contact with the heating surface 1211. At the same time, due to the damping torque of the damper 17, the medium conveyor belt 22 is always in a pre-tightened state, so that the medium conveyor belt 22 and the heater 121 can always fit well, and the atomization efficiency is higher. Here, the positioning surface P2 refers to the plane defined by the outlet side (the side facing the inlet 251) of the contact portion of the guide structure 282 and the medium conveyor belt 22 and the inlet side (the side facing the outlet 252) of the contact portion of the guide structure 283 and the medium conveyor belt 22. Alternatively, the positioning surface P2 can also be understood as a plane where the side surface of the medium conveying belt 22 in contact with the guide structures 282 and 283 is located due to the limitation of the guide structures 282 and 283 when the heater 121 is not installed.

Furthermore, the heating surface 1211 may be parallel to the positioning surface P2 formed by the guide structures 282 and 283 for the medium conveying belt 22 , so that the contact between the heating surface 1211 and the medium conveying belt 22 is more uniform and the atomization is more uniform.

Specifically, in this embodiment, the heating surface 1211 is located on the upper surface of the heater 121, and the plane P1 where the heating surface 1211 is located is higher than the positioning surface P2 formed by the guide structures 282 and 283 for the medium conveying belt 22, and the heating surface 1211 is parallel to the plane defined by the central axis of the guide structures 282 and 283. The upper surface of the heater 121 is in contact with the medium conveying belt 22, so that the heater 121 can also play a role in supporting the medium conveying belt 22. It can be understood that in other embodiments, the heating surface 1211 can also be located on the lower surface of the heater 121, in which case the plane P1 where the heating surface 1211 is located is lower than the positioning surface P2 formed by the guide structures 282 and 283 for the medium conveying belt 22.

In some embodiments, the aerosol generating article 20 may further include a position detection sensor 289 for detecting the position of the media conveying belt 22, so as to more accurately control the operation of the driving assembly 14. The position detection sensor 289 may be disposed between the guide structure 281 and the guide structure 282, and the position detection sensor 289 may accurately detect the position of the media conveying belt 22 through the limiting of the guide structure 281 and the guide structure 282. At the same time, due to the damping torque of the damper 17, the media conveying belt 22 is always in a pre-tightened state, ensuring that the position detection of the position detection sensor 289 is more accurate. The position detection sensor 289 may be any known position sensor, such as an infrared position detection sensor.

18-21 show an aerosol generating system 100 in a third embodiment of the present invention, wherein the aerosol generating system 100 comprises an aerosol generating device 10 and an aerosol generating article 20 that cooperate with each other. The aerosol generating article 20 is used to store a substrate layer 222, and the aerosol generating device 10 is used to heat the substrate layer 222 after being powered on to generate an aerosol.

In some embodiments, one end of the aerosol generating system 100 further has a nozzle 30 for the user to inhale the aerosol generated after the atomization of the matrix layer 222. In this embodiment, the nozzle 30 is cylindrical. In other embodiments, the nozzle 30 is not limited to being cylindrical, and it can also be a flat column or other shapes.

Specifically, the aerosol generating article 20 may include a box body 21 and a medium conveying belt 22 contained in the box body 21, wherein the medium conveying belt 22 has a matrix layer 222 distributed along its length. In some embodiments, the medium conveying belt 22 may be disposed in the box body 21 in a winding manner, and the winding arrangement manner enables more medium conveying belts 22 to be stored in a limited space in the box body 21, so that a single aerosol generating article 20 can be atomized and used multiple times.

Furthermore, the aerosol generating product 20 may further include a storage tray 23 and a receiving tray 24. The unheated portion of the medium conveyor belt 22 may be wound on the storage tray 23, and the heated portion of the medium conveyor belt 22 may be wound on the receiving tray 24. By winding the medium conveyor belt 22 before and after atomization on the storage tray 23 and the receiving tray 24, respectively, poor user experience such as odor crosstalk can be avoided.

The aerosol generating device 10 includes a body 11 and a heater 121, a power supply 13, a driving assembly 14 and a main control board 15 housed in the body 11. The main control board 15 is provided with a control circuit for controlling the heater 121, and the control circuit is electrically connected to the heater 121, the power supply 13 and the driving assembly 14 respectively. The heater 121 is used to heat the matrix layer 222 in the aerosol generating product 20 in a contact or non-contact manner after being powered on to generate an aerosol. The driving assembly 14 is used to provide a driving force for the medium conveyor belt 22 to travel, so that the medium conveyor belt 22 can be unwound from the storage disk 23, heated and atomized by the heater 121, and then rewound by the storage disk 24.

In this embodiment, the heater 121 adopts a resistive heating method, which can generate heat through the Joule effect. The heater 121 has a heating surface 1211, and the heating surface 1211 is in direct contact with the medium conveyor belt 22, so as to transfer heat to the medium conveyor belt 22 for baking and heating. Further, the heater 121 can be in a sheet shape, and the heating surface 1211 is located on one side of the heater 121 along the thickness direction and can be a plane or a substantially plane, so as to facilitate full contact with the belt-shaped medium conveyor belt 22 and increase the heating area.

In addition, in this embodiment, the heating surface 1211 is located on the upper side of the heater 121 close to the suction nozzle 30 , so that the heater 121 also has the function of supporting the medium conveying belt 22 , which is beneficial to the fitting of the medium conveying belt 22 and the heater 121 .

Of course, in other embodiments, the heating surface 1211 may also be located on other sides of the heater 121, such as the lower side. In other embodiments, the heater 121 is not limited to being in the form of a sheet, but may also be in other shapes such as a columnar shape. In other embodiments, the heater 121 may also use other heating methods such as electromagnetic heating, infrared radiation, ultrasound, microwave, plasma, etc.

In some embodiments, the aerosol generating device 10 may further include a mounting seat 122, which may be made of high temperature resistant materials such as ceramic or PEEK (polyetheretherketone). One end of the heater 121 may be inserted into the mounting seat 122 and fixed to the body 11 via the mounting seat 122, which may reduce the heat transferred from the heater 121 to the body 11 and facilitate heat insulation.

In some embodiments, the drive assembly 14 is an electric drive structure, which may include a reducer 141 and an output shaft 142 connected to the reducer 141, and the reducer 141 outputs the driving force through the output shaft 142. In other embodiments, the drive assembly 14 may also include other electric drive structures such as a motor. In other embodiments, the drive assembly 14 is also not limited to an electric drive structure, and it may also include a manual drive structure, such as a handle or a handwheel.

The body 11 may be roughly in the shape of a rectangular parallelepiped, and a socket 1110 for the nozzle 30 to extend out is formed at the upper end of the body 11, and a receiving cavity 1120 for receiving the aerosol generating product 20 is formed in the body 11. The aerosol generating product 20 is detachably connected to the receiving cavity 1120. When the matrix layer 222 in the aerosol generating product 20 is used up, the matrix layer 222 can be updated by replacing the aerosol generating product 20. The aerosol generating device 10 can be reused, thereby reducing the use cost of the aerosol generating system 100. Of course, in other embodiments, the body 11 is not limited to being in the shape of a rectangular parallelepiped, and it can also be in other shapes such as a cylindrical shape, a racetrack-shaped column or an elliptical column.

In some embodiments, the aerosol generating device 10 may further include a sliding cover 116, which may be slidably disposed on the body 11 to cover or expose the socket 1110. When the aerosol generating device 10 is not needed, the sliding cover 116 may be pushed to cover the socket 1110 to prevent dust from entering the socket 1110. When the aerosol generating device 10 is needed, the sliding cover 116 may be pushed to expose the socket 1110 so that the nozzle 30 can pass through the socket 1110.

In some embodiments, the body 11 may include a frame 112 and a cover 111 and a base 113 respectively matched with the frame 112. The cover 111 and the base 113 may be respectively arranged on both sides of the frame 112 along the thickness direction. An installation cavity 1130 is formed between the frame 112 and the base 113, and the installation cavity 1130 can be used to accommodate components such as the power supply 13, the reducer 141, and the main control board 15. The base 113 and the frame 112 can be connected together in a detachable manner to facilitate maintenance, replacement or upgrading of components in the installation cavity 1130. Of course, the base 113 and the frame 112 can also be connected together in a non-detachable manner to prevent users from accidentally opening the installation cavity 1130 and causing damage to components.

The frame 112 may be recessed on one side of the box body 21 to form a mounting cavity 1121 for accommodating the mounting seat 122. One end of the heater 121 is inserted into the mounting seat 122 and fixed in the mounting cavity 1121 via the mounting seat 122. The other end of the heater 121 may pass through the box body 21 to heat the medium conveying belt 22 in the box body 21.

A receiving cavity 1120 for receiving the aerosol generating product 20 is formed between the cover 111 and the frame 112. The cover 111 and the frame 112 can be connected together in a detachable manner such as a snap connection, a threaded connection, a magnetic connection, etc., so that the aerosol generating product 20 can be taken out and replaced by opening the cover 111. In this embodiment, at least one magnet 114 is embedded on the side of the cover 111 facing the frame 112, and at least one magnet 115 is embedded on the side of the frame 112 facing the cover 111 corresponding to the at least one magnet 114, so that the cover 111 and the frame 112 are magnetically fixed to each other through the magnets 114 and 115.

In some embodiments, the cover 111 may be formed entirely or at least partially of a transparent material. The term "transparent" is used to describe a material that allows at least a significant portion of incident light to pass through it, allowing for seeing through the material. In the present invention, a substantially transparent material may allow enough light to pass through it so that the media transport belt 22 within the cover 111 is visible.

The cover 111 may be completely transparent; alternatively, the cover 111 may have a lower level of transparency while still transmitting enough light to allow the media conveyor belt 22 within the cover 111 to be visible. Further, the cover 111 may include one or more areas formed of a transparent material so that a portion of the media conveyor belt 22 is visible through the one or more areas. In addition, the area formed of the transparent material may be colored, tinted, or colorless. Of course, in other embodiments, the cover 111 may also be made of an opaque material.

As shown in FIGS. 22-25 , a cavity 210 is formed in the box body 21, and the medium conveyor belt 22, the storage tray 23, and the receiving tray 24 are all received in the cavity 210. In the embodiment, the box body 21 and the cavity 210 are both roughly in the shape of a rectangular parallelepiped, and the storage tray 23 and the receiving tray 24 are arranged side by side along the length direction of the cavity 210. In other embodiments, the box body 21 and the cavity 210 are not limited to being in the shape of a rectangular parallelepiped, and of course, the arrangement of the storage tray 23 and the receiving tray 24 is also not limited. In other embodiments, the aerosol generating product 20 may also not include the box seat 211 and/or the box cover 212.

The box body 21 may include a box seat 211 and a box cover 212 that cooperate with each other. The cavity 210 is formed between the box seat 211 and the box cover 212. Specifically, the cavity 210 may be formed by a depression of the box seat 211 or the box cover 212, or may be formed by a depression of both the box seat 211 and the box cover 212. The box seat 211 and the box cover 212 may be fixed together in a detachable or non-detachable manner such as a threaded connection, a snap connection, a magnetic connection, or an adhesive connection.

In this embodiment, the cavity 210 is formed by a depression on one side of the box seat 211 along the thickness direction, and the box cover 212 is disposed at the open mouth of the cavity 210 to seal the cavity 210, and the box cover 212 and the box seat 211 are fixed to each other by a plurality of screws 213.

In some embodiments, the box body 21 may be formed entirely or at least partially of a transparent material, so that the medium conveying belt 22 in the box body 21 is visible. Of course, in other embodiments, the box body 21 may also be made of an opaque material.

The storage tray 23 and the receiving tray 24 are rotatably disposed in the box body 21. The storage tray 23 can rotate in a preset direction to unwind the medium conveying belt 22, and the receiving tray 24 can rotate in a direction that is the same as or opposite to the preset direction to rewind the medium conveying belt 22. In this embodiment, the storage tray 23 is configured to rotate in a clockwise direction (or counterclockwise direction in other embodiments) to unwind the medium conveying belt 22, and the receiving tray 24 is configured to rotate in a clockwise direction (or counterclockwise direction in other embodiments) to rewind the medium conveying belt 22.

In this embodiment, the storage tray 24 is a driving wheel and is connected to the driving assembly 14, and the storage tray 23 is a driven wheel. The storage tray 24 rotates under the drive of the driving assembly 14 to reel in the medium conveying belt 22, thereby driving the storage tray 23 to rotate synchronously to unwind the medium conveying belt 22. In other embodiments, the storage tray 23 and the storage tray 24 can also be driving wheels and can be connected to the driving assembly 14 respectively. In other embodiments, the storage tray 23 and the storage tray 24 can also rotate asynchronously. For example, the storage tray 23 first unwinds a section of the medium conveying belt 22, and after heating is completed, the storage tray 24 is driven to rotate for rewinding.

The medium conveyor belt 22 may include a belt-shaped base belt 221 and a matrix layer 222 disposed on the base belt 221. The matrix layer 222 may include one or more atomizing media such as solid and gel, and is used to generate aerosol after heating. The base belt 221 is used to carry the matrix layer 222.

The base belt 221 has a first surface 2211 and a second surface 2212 that are arranged opposite to each other in the thickness direction. When the medium conveying belt 22 is wound on the storage disk 23 and the receiving disk 24, the second surface 2212 of the base belt 221 may face the central axis of the storage disk 23 and the receiving disk 24, and the first surface 2211 of the base belt 221 is relatively far away from the central axis of the storage disk 23 and the receiving disk 24. The matrix layer 222 may be arranged on the first surface 2211 and/or the second surface 2212 of the base belt 221 by coating, lamination or bonding. In addition, the matrix layer 222 may be distributed continuously on the base belt 221, or may be distributed at intervals in different regions.

Specifically, in this embodiment, the matrix layer 222 is disposed on the first surface 2211 of the base tape 221. Of course, in other embodiments, the matrix layer 222 may also be disposed on the second surface 2212 of the base tape 221, or disposed on both the first surface 2211 and the second surface 2212 of the base tape 221.

Furthermore, the base belt 221 may be made of a heat-conducting material, such as a heat-conducting metal material such as aluminum foil or copper foil. Of course, the base belt 221 may also be made of a heat-conducting non-metallic material, such as graphite. In other embodiments, the medium conveyor belt 22 may also be made entirely of the matrix layer 222, that is, the medium conveyor belt 22 does not include the base belt 221.

The heater 121 can contact the side of the medium conveying belt 22 where the matrix layer 222 is not provided (in this embodiment, the second surface 2212 of the medium conveying belt 22), and transfer heat to the matrix layer 222 through the base belt 221. In this way, it is possible to prevent the heated matrix layer 222 from adhering to the heater 121, thereby affecting the heating effect of the heater 121. Of course, in other embodiments, the heater 121 can also directly contact the matrix layer 222, which is conducive to improving the heat transfer efficiency and reducing the heat loss. In this case, the medium conveying belt 22 does not need to be made of a heat-conducting material.

In some embodiments, the bottom wall of the cavity 210 may also protrude to form a partition 214 and a partition 215, and the inner wall surfaces of the partition 214 and the partition 215 respectively define a first receiving space 2140 and a second receiving space 2150, and the storage disk 23 and the receiving disk 24 are rotatably disposed in the first receiving space 2140 and the second receiving space 2150. One side of the first receiving space 2140 has an outlet 2141, and one side of the second receiving space 2150 has an inlet 2151, and the medium conveying belt 22 wound on the storage disk 23 can pass through the outlet 2141 and be rolled up on the receiving disk 24 through the inlet 2151.

The parts of the medium conveyor belt 22 before and after atomization are respectively contained in the first containing space 2140 and the second containing space 2150. Since the matrix layer 222 usually becomes more fluffy after atomization, the thickness of the medium conveyor belt 22 becomes larger. In order to better utilize the space in the cavity 210, the diameter of the second containing space 2150 can be designed to be larger than the diameter of the first containing space 2140. Of course, in other embodiments, without considering the spatial size of the cavity 210, the diameter of the second containing space 2150 can also be less than or equal to the diameter of the first containing space 2140.

In this embodiment, the partition 214 and the partition 215 are respectively in the shape of an arc with one side open, and the partition 214 and the partition 215 are connected to form an S-shaped structure, and the partition 214 is located on the lower side of the partition 215, and the partition 214 is located on the side of the partition 215 away from the suction nozzle 30. Of course, in other embodiments, the structure of the partition 214 and the partition 215 can also be deformed in other ways, for example, the partition 214 and the partition 215 can also be not connected together, and for another example, the partition 214 and/or the partition 215 can also be in other shapes such as an ellipse or a square. Of course, in other embodiments, the partition 214 and the partition 215 can also be arranged side by side in the horizontal direction, or can also be inclined at a certain angle to the horizontal direction or the vertical direction.

The storage disk 23 may include a storage reel 233 and a storage chassis 231 and a storage disk cover 232 respectively disposed at both ends of the storage reel 233. A mounting hole 2142 is formed on the cassette seat 211, and one end of the storage reel 233 is rotatably mounted in the mounting hole 2142. The unheated portion of the medium conveying belt 22 may be wound on the storage reel 233, and the storage chassis 231 and the storage disk cover 232 may limit the floating space of the medium conveying belt 22 in the axial direction of the storage reel 233 to prevent the medium conveying belt 22 from coming out during the winding process. During assembly, the storage chassis 231 may be first mounted on the cassette seat 211, and the storage chassis 231 may be able to rotate smoothly on the cassette seat 211, and then the medium conveying belt 22 may be stored in the storage disk 23 in a winding manner, and finally the storage disk cover 232 may be covered.

In this embodiment, the storage chassis 231 and the storage disk cover 232 are both in the shape of a disk, and the storage reel 233 is in the shape of a cylinder and is coaxially arranged with the storage chassis 231 and the storage disk cover 232, so that the medium conveying belt 22 wound on the storage reel 233 can also be in the shape of a cylinder. Of course, in other embodiments, the storage reel 233 can also be in other shapes such as an ellipse or a square. The shape of the radial cross section of the storage chassis 231 and the storage disk cover 232 can match (be the same as or similar to) the shape of the radial cross section of the storage reel 233, or can also not match (be different from or different from) the shape of the radial cross section of the storage reel 233.

In this embodiment, the storage reel 233 is integrally formed with the storage chassis 231, and can be formed by extending axially from the middle portion of one side of the storage chassis 231. In other embodiments, the storage reel 233 can also be integrally formed with the storage disc cover 232, or the storage reel 233 can also be partially formed on the storage chassis 231 and partially formed on the storage disc cover 232, or the storage reel 233 can also be a separately formed component.

In some embodiments, the distance between the storage chassis 231 and the storage tray cover 232 is greater than the width of the medium conveying belt 22, so that the medium conveying belt 22 does not generate friction with the storage chassis 231 and the storage tray cover 232, so that the medium conveying belt 22 can move smoothly without getting stuck. Here, the distance between the storage chassis 231 and the storage tray cover 232 refers to the distance between the side of the storage chassis 231 facing the storage tray cover 232 and the side of the storage tray cover 232 facing the storage chassis 231.

It can be understood that in other embodiments, the distance between the storage chassis 231 and the storage disc cover 232 may also be equal to the width of the medium conveying belt 22, so that the movement of the medium conveying belt 22 is more stable. In other embodiments, the storage reel 233 may be provided with the storage chassis 231 or the storage disc cover 232 at only one end, and the other end of the medium conveying belt 22 may be limited by the box cover 212 or the box seat 211. Of course, in other embodiments, the storage reel 233 may not be provided with the storage chassis 231 and the storage disc cover 232 at both ends.

Similarly, the storage tray 24 may also include a storage reel 243 and a storage chassis 241 and a storage tray cover 242 respectively disposed at both ends of the storage reel 243. A mounting hole 2152 is formed on the cassette seat 211, and one end of the storage reel 233 is rotatably mounted in the mounting hole 2152. The heated portion of the medium conveyor belt 22 may be wound on the storage reel 243, and the storage chassis 241 and the storage tray cover 242 may limit the floating space of the medium conveyor belt 22 in the axial direction of the storage reel 243 to prevent the medium conveyor belt 22 from coming out during the winding process. During assembly, the storage chassis 241 may be first mounted on the cassette seat 211, and the storage chassis 241 may be able to rotate smoothly on the cassette seat 211, and then the atomized portion of the medium conveyor belt 22 may be stored in the storage tray 24 in a winding manner, and finally the storage tray cover 242 may be covered.

In this embodiment, the storage chassis 241 and the storage tray cover 242 are both in the shape of a disk, and the storage reel 243 is in the shape of a cylinder and is coaxially arranged with the storage chassis 241 and the storage tray cover 242, so that the medium conveying belt 22 wound on the storage reel 243 can also be in the shape of a cylinder. Of course, in other embodiments, the storage reel 243 can also be in other shapes such as an ellipse or a square. The shape of the radial cross section of the storage chassis 241 and the storage tray cover 242 can match (be the same as or similar to) the shape of the radial cross section of the storage reel 243, or can also not match (be different from or different from) the shape of the radial cross section of the storage reel 243.

In some embodiments, the storage reel 243 may include a shaft segment 2431 integrally formed with the storage chassis 241 and a shaft segment 2432 integrally formed with the storage tray cover 242, and the shaft segments 2431 and 2432 are mutually sleeved to form the storage reel 243. In other embodiments, the storage reel 243 may also be formed by only extending the storage chassis 241 or the storage tray cover 242, or the storage reel 243 may also be a separately formed component.

In some embodiments, the distance between the storage chassis 241 and the storage tray cover 242 is greater than the width of the medium conveyor belt 22, so that the medium conveyor belt 22 does not generate friction with the storage chassis 241 and the storage tray cover 242, so that the medium conveyor belt 22 can move smoothly without getting stuck. Here, the distance between the storage chassis 241 and the storage tray cover 242 refers to the distance between the side of the storage chassis 241 facing the storage tray cover 242 and the side of the storage tray cover 242 facing the storage chassis 241.

It can be understood that in other embodiments, the distance between the storage chassis 241 and the storage tray cover 242 may also be equal to the width of the medium conveying belt 22, so that the movement of the medium conveying belt 22 is more stable. In other embodiments, the storage reel 243 may also be provided with the storage chassis 241 or the storage tray cover 242 at only one end, and the position limitation of the other end of the medium conveying belt 22 may be achieved by the box cover 212 or the box seat 211. Of course, in other embodiments, the storage reel 243 may not be provided with the storage chassis 241 and the storage tray cover 242 at both ends.

The storage reel 243 is formed with an insertion hole 244, and the output shaft 142 can pass through the box seat 211 and be inserted into the insertion hole 244. In some embodiments, the radial cross-section of the insertion hole 244 and the output shaft 142 can be a non-circular shape such as a D-shape, a quadrilateral, a polygon, an ellipse, etc., so that the output shaft 142 can be circumferentially fixed in the insertion hole 244, so that the reducer 141 can drive the storage tray 24 to rotate, and the plug-in matching method makes it easy to assemble and disassemble the aerosol generating product 20 and the aerosol generating device 10. Of course, in other embodiments, the output shaft 142 can also be connected to the storage tray 24 in other ways, such as threaded connection, pin connection, etc.

In some embodiments, the aerosol generating article 20 may further include a damping assembly 26, which is connected to the storage disk 23 and is used to provide a damping torque during the rotation of the storage disk 23 relative to the box body 21. The storage disk 24 rotates under the drive of the reducer 141 to drive the medium conveying belt 22 to move. Due to the damping torque of the storage disk 23, the medium conveying belt 22 will be in a taut state, so that the medium conveying belt 22 achieves a pre-tightening effect during the movement, so that the medium conveying belt 22 can maintain a good fit with the heater 121. Here, the torque of the reducer 141 = κ * F1 * (R1/R2) / η, where κ is a safety factor, F1 is a damping torque, η is a transmission efficiency of the reducer 141, R1 is the radius of the portion of the medium conveying belt 22 wound on the storage disk 24, and R2 is the radius of the portion of the medium conveying belt 22 wound on the storage disk 23.

Specifically, the storage disk 23 and the box body 21 have a friction surface 2311 and a friction surface 2144 respectively. When the storage disk 23 rotates relative to the box body 21, relative friction rotation occurs between the friction surface 2311 and the friction surface 2144, thereby generating friction damping. The friction damping causes the storage disk 23 to generate a damping torque F1 in the opposite direction of its rotation when rotating.

In some embodiments, the damping assembly 26 may include an elastic member 260, such as a spring, a spring sheet, a silicone member, etc. The elastic member 260 is respectively in contact with the storage disk 23 and the box body 21, and the friction surface 2311 of the storage disk 23 is elastically pressed against the friction surface 2144 of the box body 21 through the elastic deformation of the elastic member 260. The storage disk 23 and the box body 21 have a limiting surface 235 and a limiting surface 216, respectively. The two ends of the elastic member 260 are respectively pressed against the limiting surface 235 and the limiting surface 216, and elastic deformation is generated by pressure, thereby applying an elastic force to the storage disk 23, so that the friction surface 2311 is pressed against the friction surface 2144. Further, the limiting surface 235 and the limiting surface 216 can be arranged opposite to each other in the axial direction of the storage disk 23, so that the elastic force generated by the elastic member 260 under pressure is along the axial direction of the storage disk 23.

In some embodiments, the bottom wall of the first receiving space 2140 may be protruded to form a friction protrusion 2143, and the side of the storage base 231 away from the storage disk cover 232 may abut against the friction protrusion 2143. The side of the friction protrusion 2143 in contact with the storage base 231 forms a friction surface 2144, and correspondingly, the surface of the storage base 231 in contact with the friction protrusion 2143 forms a friction surface 2311. In this embodiment, the friction protrusion 2143 is annular, and its center line coincides with the rotation center line of the storage disk 23.

It can be understood that in other embodiments, the friction protrusion 2143 can also be formed on the storage disk 23. Of course, in other embodiments, there can be multiple friction protrusions 2143, and/or the friction protrusion 2143 is not limited to being in a circular ring shape. For example, there are multiple friction protrusions 2143, and the multiple friction protrusions 2143 are in a circular ring shape arranged concentrically. For another example, there are multiple friction protrusions 2143, and the multiple friction protrusions 2143 can be in an arc shape and arranged at intervals in the circumferential direction and/or radial direction of the storage disk cover 232.

In this embodiment, the elastic member 260 is a spring 266, which can be arranged in the storage reel 233, and the two ends of the spring 266 respectively abut against the limiting surface 235 and the limiting surface 216, so that the storage disk 23 is elastically pressed against the friction protrusion 2143 of the box seat 211. A damping hole 234 is formed on the storage reel 233, and one end of the damping hole 234 is open, and the other end forms a limiting surface 235. The spring 266 can be installed into the damping hole 234 from the open side of the damping hole 234, and abut against the limiting surface 235. Preferably, the central axis of the damping hole 234, the spring 266, and the storage disk 23 are all coincident, which is conducive to uniform force on the storage disk 23.

A boss 2121 may be formed on one side of the box cover 212 facing the box seat 211, and the boss 2121 may extend into the damping hole 234, and an end surface of the boss 2121 facing the box seat 211 forms a limiting surface 216. It can be understood that in other embodiments, the box cover 212 may not be provided with the boss 2121, and the spring 266 may directly abut against the box cover 212.

After the box cover 212 is fixed to the box seat 211, the boss 2121 can compress the spring 266, so that the spring 266 applies an elastic force F2 toward the box seat 211 to the storage chassis 231. Under the action of the elastic force F2, the storage chassis 231 generates friction between the friction surfaces 2311 and 2144 during relative rotation, thereby generating a damping torque F1. Generally, the damping torque F1 on the storage tray 23 can be adjusted by adjusting the elastic force F2 of the spring 266.

Specifically, in this embodiment, the damping torque F1=F2*U*R3, wherein U is the friction coefficient between the friction surface 2311 and the friction surface 2144, and R3 is the contact radius between the friction surface 2311 and the friction surface 2144. In this embodiment, R3=(maximum radius of the friction surface 2144+minimum radius of the friction surface 2144)/2.

In some embodiments, the aerosol generating article 20 may further include an atomizing seat 25, in which an atomizing chamber 250 is formed, and an inlet 251 and an outlet 252 are formed on the side wall of the atomizing seat 25, which are connected to the atomizing chamber 250. The medium conveying belt 22 can enter the atomizing chamber 250 through the inlet 251, and after being heated and atomized in the atomizing chamber 250, it can be transmitted through the outlet 252. One end of the heater 121 can extend into the atomizing chamber 250 to heat the medium conveying belt 22 entering the atomizing chamber 250.

In some embodiments, the atomizer seat 25 can be installed together with the box seat 211 in a detachable manner, and the atomizer seat 25 can be reused to reduce replacement costs. Of course, in its embodiments, the atomizer seat 25 can also be installed together with the box seat 211 in a non-detachable manner, or the atomizer seat 25 can also be integrally formed with the box seat 211.

In some embodiments, the cross-section of the inlet 251 and the outlet 252 (here, the cross-section perpendicular to the direction of travel of the medium conveyor belt 22) may be the same or similar to the cross-section of the medium conveyor belt 22 (here, the cross-section perpendicular to the direction of travel of the medium conveyor belt 22). In addition, a clearance fit may be adopted between the inlet 251, the outlet 252 and the medium conveyor belt 22, so that the medium conveyor belt 22 can move smoothly without getting stuck, and the edges of the inlet 251 and the outlet 252 can be prevented from scratching the medium conveyor belt 22. In addition, the annular gap 2510 formed between the periphery of the inlet 251 and the medium conveyor belt 22 and/or the annular gap 2520 formed between the periphery of the outlet 252 and the medium conveyor belt 22 can also be used as an airflow channel to connect the atomization chamber 250 with the receiving chamber 210, and then with the outside world.

It is understandable that the size of the annular gap 2510 and the annular gap 2520 should not be too small, otherwise it may cause excessive suction resistance, resulting in too low pressure in the atomizing chamber 250 and causing suction turbulence, affecting the suction experience. Of course, the size of the annular gap 2510 and the annular gap 2520 should not be too large, reducing or avoiding the leakage of the aerosol generated in the atomizing chamber 250 through the inlet 251 and the outlet 252.

Specifically, in the present embodiment, the atomizer seat 25 is arranged on the upper side of the box seat 211, and may include a main body 254 and an extension portion 255 extending upward from the main body 254. The main body 254 can be accommodated in the upper side of the cavity 210, the atomizer cavity 250 is formed in the main body 254, and the inlet 251 and the outlet 252 are respectively formed on the two opposite sides of the atomizer seat 25. An air outlet channel 253 connected to the atomizer cavity 250 is formed in the extension portion 255, and the lower end of the suction nozzle 30 is connected to the air outlet channel 253. The extension portion 255 can extend out of the box body 21, so as to facilitate mutual plug-in cooperation with the suction nozzle 30. A vent 2550 that connects the air outlet channel 253 with the outside world can also be formed on the side wall of the extension portion 255.

Of course, in other embodiments, the atomizer seat 25 may also be disposed at other positions of the box body 21. In addition, the configuration of the inlet 251 and the outlet 252 is not limited, for example, the inlet 251 and the outlet 252 may be disposed on the same side of the atomizer seat 25; or, the inlet 251 is disposed on one lateral side of the atomizer seat 25, and the outlet 252 is disposed on the bottom side of the atomizer seat 25.

In some embodiments, the aerosol generating article 20 may further include a guide structure 28 disposed in the cavity 210, which is used to guide the medium conveying belt 22 during its travel, to ensure smooth transmission of the medium conveying belt 22, and to ensure good contact between the medium conveying belt 22 and the heater 121. In some embodiments, the aerosol generating article 20 may include a plurality of guide structures 28, which are spaced apart on the transmission path of the medium conveying belt 22.

In some embodiments, the plurality of guide structures 28 may include a limiting roller 28a, a limiting roller 28b, and a limiting roller 28c sequentially distributed on the transmission path of the medium conveyor belt 22, and the rolling friction of each limiting roller ensures the smooth transmission of the medium conveyor belt 22. The medium conveyor belt 22 to be heated sequentially passes through the limiting roller 28a, the limiting roller 28b, and the inlet 251 into the atomizing chamber 250 for atomization, and the atomized medium conveyor belt 22 is output from the outlet 252 and then guided by the limiting roller 28c, and then rolled up on the storage tray 24. Of course, in other embodiments, the guide structure 28 may also include other structures such as convex ribs and convex columns.

The limiting roller 28a is arranged near the outlet 2141, so that the medium conveying belt 22 wound on the storage disk 23 can be smoothly transmitted, and the transmission of the medium conveying belt 22 is not affected by the change in the size of the medium conveying belt 22 wound on the storage disk 23. The limiting roller 28b and the limiting roller 28c are respectively arranged on two opposite sides of the atomizing seat 25 in the lateral direction, so as to make the medium conveying belt 22 in good contact with the heater 121. It should be noted that the limiting roller 28b and the limiting roller 28c are respectively arranged corresponding to the inlet 251 and the outlet 252. When the setting positions of the inlet 251 and the outlet 252 are changed, the setting positions of the limiting roller 28b and the limiting roller 28c can be changed accordingly.

Furthermore, a limiting roller 28d can be provided between the limiting roller 28c and the storage tray 24. The limiting roller 28d can increase the turning angle of the medium conveying belt 22 when passing through the limiting roller 28c, thereby improving the stratification problem caused by the atomized medium conveying belt 22 passing through the corner due to the small turning angle.

Figure 26 shows an aerosol generating product 20 in some modified embodiments of the present invention. The main difference between them and the above-mentioned embodiments is that the damping component 26 in this embodiment includes a soft structural member 267. The soft structural member 267 can be made of soft materials such as silicone and can be elastically deformed after being compressed, so that when the storage disk 23 rotates relative to the box body 21, friction is generated between the storage disk 23 and the box body 21, thereby providing damping torque for the storage disk 23.

Specifically, a damping hole 234 may be formed in the axial direction of the storage reel 233, and the soft structural member 267 is accommodated in the damping hole 234. Further, the cassette seat 211 may be formed with a guide column 2111 protruding toward the damping hole 234, and the soft structural member 267 may be cylindrical and interference fit between the outer wall surface of the guide column 2111 and the hole wall surface of the damping hole 234. The friction force generated by the storage disk 23 and the cassette body 21 during relative rotation can be adjusted by adjusting the interference amount and/or softness of the soft structural member 267.

One end of the guide column 2111 away from the storage disk cover 232 protrudes radially outward to form a limited surface 216, and the storage disk cover 232 forms a limited surface 235 on the side facing the cassette seat 211. The limited surface 216 and the limited surface 235 can be used to limit the axial position of the soft structure 267 on the guide column 2111. The two ends of the soft structure 267 can be respectively against the limited surface 216 and the limited surface 235, so that the position of the soft structure 267 is more stable. Of course, the soft structure 267 can also have a certain floating space between the limited surface 216 and the limited surface 235.

In other embodiments, the above-mentioned specific structure can be arbitrarily deformed as needed. For example, the guide column 2111 can also be formed on the storage disk cover 232. For another example, the soft structural member 267 can also be in the shape of a solid cylinder. Of course, in other embodiments, a damping medium (such as damping silica gel) can be filled between the outer wall surface of the guide column 2111 and the hole wall surface of the damping hole 234, and the viscosity of the damping medium can be used to make the storage disk 23 generate damping torque when rotating relative to the box body 21.

In some embodiments, the bottom surface of the cavity 210 may also be formed with a friction surface 2144 , and the storage base 231 may contact the friction surface 2144 . When the storage disk 23 rotates relative to the box body 21 , friction is generated between the storage disk 23 and the friction surface 2144 .

In the embodiment shown in Figure 27, there is no contact between the storage chassis 231 and the bottom surface of the cavity 210, so that when the storage disk 23 rotates relative to the box body 21, no friction force will be generated between the storage disk 23 and the bottom surface of the cavity 210. Only friction force will be generated between the storage reel 233 and the guide column 2111 during relative rotation.

28-32 show an aerosol generating system 100 in a fourth embodiment of the present invention, wherein the aerosol generating system 100 comprises an aerosol generating device 10 and an aerosol generating article 20 that cooperate with each other. The aerosol generating article 20 is used to store a substrate layer 222, and the aerosol generating device 10 is used to heat the substrate layer 222 after being powered on to generate aerosol.

In some embodiments, one end of the aerosol generating system 100 further has a nozzle 30 for the user to inhale the aerosol generated after the atomization of the matrix layer 222. In this embodiment, the nozzle 30 is cylindrical. In other embodiments, the nozzle 30 is not limited to being cylindrical, and it can also be a flat column or other shapes.

Specifically, the aerosol generating article 20 may include a box body 21 and a medium conveying belt 22 contained in the box body 21, wherein the medium conveying belt 22 has a matrix layer 222 distributed along its length. In some embodiments, the medium conveying belt 22 may be disposed in the box body 21 in a winding manner, and the winding arrangement manner enables more medium conveying belts 22 to be stored in a limited space in the box body 21, so that a single aerosol generating article 20 can be atomized and used multiple times.

Furthermore, the aerosol generating product 20 may further include a storage tray 23 and a receiving tray 24. The unheated portion of the medium conveyor belt 22 may be wound on the storage tray 23, and the heated portion of the medium conveyor belt 22 may be wound on the receiving tray 24. By winding the medium conveyor belt 22 before and after atomization on the storage tray 23 and the receiving tray 24, respectively, poor user experience such as odor crosstalk can be avoided.

The aerosol generating device 10 includes a body 11 and a heater 121, a power supply 13, a driving assembly 14 and a main control board 15 housed in the body 11. The main control board 15 is provided with a control circuit for controlling the heater 121, and the control circuit is electrically connected to the heater 121, the power supply 13 and the driving assembly 14 respectively. The heater 121 is used to heat the matrix layer 222 in the aerosol generating product 20 in a contact or non-contact manner after being powered on to generate an aerosol. The driving assembly 14 is used to provide a driving force for the medium conveyor belt 22 to travel, so that the medium conveyor belt 22 can be unwound from the storage disk 23, heated and atomized by the heater 121, and then rewound by the storage disk 24.

In this embodiment, the heater 121 adopts a resistive heating method, which can generate heat through the Joule effect. The heater 121 has a heating surface 1211, and the heating surface 1211 is in direct contact with the medium conveyor belt 22, so as to transfer heat to the medium conveyor belt 22 for baking and heating. Further, the heater 121 can be in a sheet shape, and the heating surface 1211 is located on one side of the heater 121 along the thickness direction and can be a plane or a substantially plane, so as to facilitate full contact with the belt-shaped medium conveyor belt 22 and increase the heating area.

In addition, in this embodiment, the heating surface 1211 is located on the upper side of the heater 121 close to the suction nozzle 30 , so that the heater 121 also has the function of supporting the medium conveying belt 22 , which is beneficial to the fitting of the medium conveying belt 22 and the heater 121 .

Of course, in other embodiments, the heating surface 1211 may also be located on other sides of the heater 121, such as the lower side. In other embodiments, the heater 121 is not limited to being in the form of a sheet, but may also be in other shapes such as a columnar shape. In other embodiments, the heater 121 may also use other heating methods such as electromagnetic heating, infrared radiation, ultrasound, microwave, plasma, etc.

In some embodiments, the aerosol generating device 10 may further include a mounting seat 122, which may be made of high temperature resistant materials such as ceramic or PEEK (polyetheretherketone). One end of the heater 121 may be inserted into the mounting seat 122 and fixed to the body 11 via the mounting seat 122, which may reduce the heat transferred from the heater 121 to the body 11 and facilitate heat insulation.

In some embodiments, the drive assembly 14 is an electric drive structure, which may include a reducer 141 and an output shaft 142 connected to the reducer 141, and the reducer 141 outputs the driving force through the output shaft 142. In other embodiments, the drive assembly 14 may also include other electric drive structures such as a motor. In other embodiments, the drive assembly 14 is also not limited to an electric drive structure, and it may also include a manual drive structure, such as a handle or a handwheel.

The body 11 may be roughly in the shape of a rectangular parallelepiped, and a socket 1110 for the nozzle 30 to extend out is formed at the upper end of the body 11, and a receiving cavity 1120 for receiving the aerosol generating product 20 is formed in the body 11. The aerosol generating product 20 is detachably connected to the receiving cavity 1120. When the matrix layer 222 in the aerosol generating product 20 is used up, the matrix layer 222 can be updated by replacing the aerosol generating product 20. The aerosol generating device 10 can be reused, thereby reducing the use cost of the aerosol generating system 100. Of course, in other embodiments, the body 11 is not limited to being in the shape of a rectangular parallelepiped, and it can also be in other shapes such as a cylindrical shape, a racetrack-shaped column or an elliptical column.

In some embodiments, the aerosol generating device 10 may further include a sliding cover 116, which may be slidably disposed on the body 11 to cover or expose the socket 1110. When the aerosol generating device 10 is not needed, the sliding cover 116 may be pushed to cover the socket 1110 to prevent dust from entering the socket 1110. When the aerosol generating device 10 is needed, the sliding cover 116 may be pushed to expose the socket 1110 so that the nozzle 30 can pass through the socket 1110.

In some embodiments, the body 11 may include a frame 112 and a cover 111 and a base 113 respectively matched with the frame 112. The cover 111 and the base 113 may be respectively arranged on both sides of the frame 112 along the thickness direction. An installation cavity 1130 is formed between the frame 112 and the base 113, and the installation cavity 1130 can be used to accommodate components such as the power supply 13, the reducer 141, and the main control board 15. The base 113 and the frame 112 can be connected together in a detachable manner to facilitate the maintenance, replacement or upgrading of the components in the installation cavity 1130. Of course, the base 113 and the frame 112 can also be connected together in a non-detachable manner to prevent the user from accidentally opening the installation cavity 1130 and causing damage to the components.

The frame 112 may be recessed on one side of the box body 21 to form a mounting cavity 1121 for accommodating the mounting seat 122. One end of the heater 121 is inserted into the mounting seat 122 and fixed in the mounting cavity 1121 via the mounting seat 122. The other end of the heater 121 may pass through the box body 21 to heat the medium conveying belt 22 in the box body 21.

A receiving cavity 1120 for receiving the aerosol generating product 20 is formed between the cover 111 and the frame 112. The cover 111 and the frame 112 can be connected together by one or more detachable methods such as snap connection, threaded connection, magnetic connection, etc., so that the aerosol generating product 20 can be taken out and replaced by opening the cover 111. In this embodiment, at least one magnet 114 is embedded on the side of the cover 111 facing the frame 112, and at least one magnet 115 is embedded on the side of the frame 112 facing the cover 111 corresponding to the at least one magnet 114, so that the cover 111 and the frame 112 are magnetically fixed to each other through the magnets 114 and 115.

In some embodiments, the cover 111 may be formed entirely or at least partially of a transparent material. The term "transparent" is used to describe a material that allows at least a significant portion of incident light to pass through it, allowing for seeing through the material. In the present invention, a substantially transparent material may allow enough light to pass through it so that the media transport belt 22 within the cover 111 is visible.

The cover 111 may be completely transparent; alternatively, the cover 111 may have a lower level of transparency while still transmitting enough light to allow the media conveyor belt 22 within the cover 111 to be visible. Further, the cover 111 may include one or more areas formed of a transparent material so that a portion of the media conveyor belt 22 is visible through the one or more areas. In addition, the area formed of the transparent material may be colored, tinted, or colorless. Of course, in other embodiments, the cover 111 may also be made of an opaque material.

As shown in FIGS. 32-34 , a cavity 210 is formed in the box body 21, and the medium conveyor belt 22, the storage tray 23, and the receiving tray 24 are all received in the cavity 210. In the embodiment, the box body 21 and the cavity 210 are both roughly in the shape of a rectangular parallelepiped, and the storage tray 23 and the receiving tray 24 are arranged side by side along the length direction of the cavity 210. In other embodiments, the box body 21 and the cavity 210 are not limited to being in the shape of a rectangular parallelepiped, and of course, the arrangement of the storage tray 23 and the receiving tray 24 is also not limited. In other embodiments, the aerosol generating product 20 may also not include the box seat 211 and/or the box cover 212.

The box body 21 may include a box seat 211 and a box cover 212 that cooperate with each other. The cavity 210 is formed between the box seat 211 and the box cover 212. Specifically, the cavity 210 may be formed by a depression of the box seat 211 or the box cover 212, or may be formed by a depression of both the box seat 211 and the box cover 212. The box seat 211 and the box cover 212 may be fixed together in a detachable or non-detachable manner such as a threaded connection, a snap connection, a magnetic connection, or an adhesive connection.

In this embodiment, the cavity 210 is formed by a depression on one side of the box seat 211 along the thickness direction, and the box cover 212 is disposed at the open mouth of the cavity 210 to seal the cavity 210, and the box cover 212 and the box seat 211 are fixed to each other by a plurality of screws 213.

In some embodiments, the box body 21 may be formed entirely or at least partially of a transparent material, so that the medium conveying belt 22 in the box body 21 is visible. Of course, in other embodiments, the box body 21 may also be made of an opaque material.

The storage tray 23 and the receiving tray 24 are rotatably disposed in the box body 21. The storage tray 23 can rotate in a preset direction to unwind the medium conveying belt 22, and the receiving tray 24 can rotate in a direction that is the same as or opposite to the preset direction to rewind the medium conveying belt 22. In this embodiment, the storage tray 23 is configured to rotate in a clockwise direction (or counterclockwise direction in other embodiments) to unwind the medium conveying belt 22, and the receiving tray 24 is configured to rotate in a clockwise direction (or counterclockwise direction in other embodiments) to rewind the medium conveying belt 22.

In this embodiment, the storage tray 24 is a driving wheel and is connected to the driving assembly 14, and the storage tray 23 is a driven wheel. The storage tray 24 rotates under the drive of the driving assembly 14 to reel in the medium conveying belt 22, thereby driving the storage tray 23 to rotate synchronously to unwind the medium conveying belt 22. In other embodiments, the storage tray 23 and the storage tray 24 can also be driving wheels and can be connected to the driving assembly 14 respectively. In other embodiments, the storage tray 23 and the storage tray 24 can also rotate asynchronously. For example, the storage tray 23 first unwinds a section of the medium conveying belt 22, and after heating is completed, the storage tray 24 is driven to rotate for rewinding.

The medium conveyor belt 22 may include a belt-shaped base belt 221 and a matrix layer 222 disposed on the base belt 221. The matrix layer 222 may include one or more of a solid and a gel, and is used to generate an aerosol after heating. The base belt 221 is used to carry the matrix layer 222.

The base belt 221 has a first surface 2211 and a second surface 2212 that are arranged opposite to each other in the thickness direction. When the medium conveying belt 22 is wound on the storage disk 23 and the receiving disk 24, the second surface 2212 of the base belt 221 may face the central axis of the storage disk 23 and the receiving disk 24, and the first surface 2211 of the base belt 221 is relatively far away from the central axis of the storage disk 23 and the receiving disk 24. The matrix layer 222 may be arranged on the first surface 2211 and/or the second surface 2212 of the base belt 221 by coating, lamination or bonding. In addition, the matrix layer 222 may be distributed continuously on the base belt 221, or may be distributed at intervals in different regions.

Specifically, in this embodiment, the matrix layer 222 is disposed on the first surface 2211 of the base tape 221. Of course, in other embodiments, the matrix layer 222 may also be disposed on the second surface 2212 of the base tape 221, or disposed on both the first surface 2211 and the second surface 2212 of the base tape 221.

Furthermore, the base belt 221 may be made of a heat-conducting material, such as a heat-conducting metal material such as aluminum foil or copper foil. Of course, the base belt 221 may also be made of a heat-conducting non-metallic material, such as graphite. In other embodiments, the medium conveyor belt 22 may also be made entirely of the matrix layer 222, that is, the medium conveyor belt 22 does not include the base belt 221.

The heater 121 can contact the side of the medium conveying belt 22 where the matrix layer 222 is not provided (in this embodiment, the second surface 2212 of the medium conveying belt 22), and transfer heat to the matrix layer 222 through the base belt 221. In this way, it is possible to prevent the heated matrix layer 222 from adhering to the heater 121, thereby affecting the heating effect of the heater 121. Of course, in other embodiments, the heater 121 can also directly contact the matrix layer 222, which is conducive to improving the heat transfer efficiency and reducing the heat loss. In this case, the medium conveying belt 22 does not need to be made of a heat-conducting material.

In some embodiments, the bottom wall of the cavity 210 may also protrude to form a partition 214 and a partition 215, and the inner wall surfaces of the partition 214 and the partition 215 respectively define a first receiving space 2140 and a second receiving space 2150, and the storage disk 23 and the receiving disk 24 are rotatably disposed in the first receiving space 2140 and the second receiving space 2150. One side of the first receiving space 2140 has an outlet 2141, and one side of the second receiving space 2150 has an inlet 2151, and the medium conveying belt 22 wound on the storage disk 23 can pass through the outlet 2141 and be rolled up on the receiving disk 24 through the inlet 2151.

The parts of the medium conveyor belt 22 before and after atomization are respectively contained in the first containing space 2140 and the second containing space 2150. Since the matrix layer 222 usually becomes more fluffy after atomization, the thickness of the medium conveyor belt 22 becomes larger. In order to better utilize the space in the cavity 210, the diameter of the second containing space 2150 can be designed to be larger than the diameter of the first containing space 2140. Of course, in other embodiments, without considering the spatial size of the cavity 210, the diameter of the second containing space 2150 can also be less than or equal to the diameter of the first containing space 2140.

In this embodiment, the partition 214 and the partition 215 are respectively in the shape of an arc with one side open, and the partition 214 and the partition 215 are connected to form an S-shaped structure, and the partition 214 is located on the lower side of the partition 215, and the partition 214 is located on the side of the partition 215 away from the suction nozzle 30. Of course, in other embodiments, the structure of the partition 214 and the partition 215 can also be deformed in other ways, for example, the partition 214 and the partition 215 can also be not connected together, and for another example, the partition 214 and/or the partition 215 can also be in other shapes such as an ellipse or a square. Of course, in other embodiments, the partition 214 and the partition 215 can also be arranged side by side in the horizontal direction, or can also be inclined at a certain angle to the horizontal direction or the vertical direction.

The storage tray 23 may include a storage reel 233 and a storage chassis 231 and a storage tray cover 232 respectively disposed at both ends of the storage reel 233. The unheated portion of the medium conveying belt 22 may be wound on the storage reel 233, and the storage chassis 231 and the storage tray cover 232 may limit the floating space of the medium conveying belt 22 in the axial direction of the storage reel 233 to prevent the medium conveying belt 22 from coming out during the winding process. During assembly, the storage chassis 231 may be first installed on the cassette seat 211, and the storage chassis 231 may be able to rotate smoothly on the cassette seat 211, and then the medium conveying belt 22 may be stored in the storage tray 23 in a winding manner, and finally the storage tray cover 232 may be covered.

In this embodiment, the storage chassis 231 and the storage disk cover 232 are both in the shape of a disk, and the storage reel 233 is in the shape of a cylinder and is coaxially arranged with the storage chassis 231 and the storage disk cover 232, so that the medium conveying belt 22 wound on the storage reel 233 can also be in the shape of a cylinder. Of course, in other embodiments, the storage reel 233 can also be in other shapes such as an ellipse or a square. The shape of the radial cross section of the storage chassis 231 and the storage disk cover 232 can match (be the same as or similar to) the shape of the radial cross section of the storage reel 233, or can also not match (be different from or different from) the shape of the radial cross section of the storage reel 233.

In this embodiment, the storage reel 233 is integrally formed with the storage chassis 231, and can be formed by extending axially from the middle portion of one side of the storage chassis 231. In other embodiments, the storage reel 233 can also be integrally formed with the storage disc cover 232, or the storage reel 233 can also be partially formed on the storage chassis 231 and partially formed on the storage disc cover 232, or the storage reel 233 can also be a separately formed component.

In some embodiments, the distance between the storage base 231 and the storage base cover 232 is greater than the width of the medium conveyor belt 22, so that the medium conveyor belt 22 does not generate friction with the storage base 231 and the storage base cover 232, allowing the medium conveyor belt 22 to move smoothly without getting stuck.

It can be understood that in other embodiments, the distance between the storage chassis 231 and the storage disc cover 232 may also be equal to the width of the medium conveying belt 22, so that the movement of the medium conveying belt 22 is more stable. In other embodiments, the storage reel 233 may be provided with the storage chassis 231 or the storage disc cover 232 at only one end, and the other end of the medium conveying belt 22 may be limited by the box cover 212 or the box seat 211. Of course, in other embodiments, the storage reel 233 may not be provided with the storage chassis 231 and the storage disc cover 232 at both ends.

Similarly, the storage tray 24 may also include a storage reel 243 and a storage chassis 241 and a storage tray cover 242 respectively disposed at both ends of the storage reel 243. A mounting hole 2152 is formed on the cassette seat 211, and one end of the storage reel 233 is rotatably mounted in the mounting hole 2152. The heated portion of the medium conveyor belt 22 may be wound on the storage reel 243, and the storage chassis 241 and the storage tray cover 242 may limit the floating space of the medium conveyor belt 22 in the axial direction of the storage reel 243 to prevent the medium conveyor belt 22 from coming out during the winding process. During assembly, the storage chassis 241 may be first mounted on the cassette seat 211, and the storage chassis 241 may be able to rotate smoothly on the cassette seat 211, and then the atomized portion of the medium conveyor belt 22 may be stored in the storage tray 24 in a winding manner, and finally the storage tray cover 242 may be covered.

In this embodiment, the storage chassis 241 and the storage tray cover 242 are both in the shape of a disk, and the storage reel 243 is in the shape of a cylinder and is coaxially arranged with the storage chassis 241 and the storage tray cover 242, so that the medium conveying belt 22 wound on the storage reel 243 can also be in the shape of a cylinder. Of course, in other embodiments, the storage reel 243 can also be in other shapes such as an ellipse or a square. The shape of the radial cross section of the storage chassis 241 and the storage tray cover 242 can match (be the same as or similar to) the shape of the radial cross section of the storage reel 243, or can also not match (be different from or different from) the shape of the radial cross section of the storage reel 243.

In some embodiments, the storage reel 243 may include a shaft segment 2431 integrally formed with the storage chassis 241 and a shaft segment 2432 integrally formed with the storage tray cover 242, and the shaft segments 2431 and 2432 are mutually sleeved to form the storage reel 243. In other embodiments, the storage reel 243 may also be formed by only extending the storage chassis 241 or the storage tray cover 242, or the storage reel 243 may also be a separately formed component.

In some embodiments, the distance between the storage chassis 241 and the storage tray cover 242 is greater than the width of the medium conveyor belt 22, so that the medium conveyor belt 22 does not generate friction with the storage chassis 241 and the storage tray cover 242, allowing the medium conveyor belt 22 to move smoothly without getting stuck.

It can be understood that in other embodiments, the distance between the storage chassis 241 and the storage tray cover 242 may also be equal to the width of the medium conveying belt 22, so that the movement of the medium conveying belt 22 is more stable. In other embodiments, the storage reel 243 may also be provided with the storage chassis 241 or the storage tray cover 242 at only one end, and the position limitation of the other end of the medium conveying belt 22 may be achieved by the box cover 212 or the box seat 211. Of course, in other embodiments, the storage reel 243 may not be provided with the storage chassis 241 and the storage tray cover 242 at both ends.

The storage reel 243 is formed with an insertion hole 244, and the output shaft 142 can pass through the box seat 211 and be inserted into the insertion hole 244. In some embodiments, the radial cross-section of the insertion hole 244 and the output shaft 142 can be a non-circular shape such as a D-shape, a quadrilateral, a polygon, an ellipse, etc., so that the output shaft 142 can be circumferentially fixed in the insertion hole 244, so that the reducer 141 can drive the storage tray 24 to rotate, and the plug-in matching method makes it easy to assemble and disassemble the aerosol generating product 20 and the aerosol generating device 10. Of course, in other embodiments, the output shaft 142 can also be connected to the storage tray 24 in other ways, such as threaded connection, pin connection, etc.

In some embodiments, the aerosol generating article 20 may further include a damping assembly 26, which is used to provide a damping torque during the rotation of the storage disk 23 relative to the box body 21. The storage disk 24 is driven by the reducer 141 to rotate and drive the medium conveying belt 22 to move. Due to the damping torque of the storage disk 23, the medium conveying belt 22 will be in a taut state, so that the medium conveying belt 22 can achieve a pre-tightening effect during the movement, so that the medium conveying belt 22 can maintain a good fit with the heater 121.

As shown in FIGS. 33-36 , the damping assembly 26 includes a first damping member 261 connected to the storage disk 23, a second damping member 262 connected to the box body 21, and a torsion elastic element 263 connected to the first damping member 261 and the second damping member 262, respectively. The first damping member 261 is fixed relative to the storage disk 23 in the circumferential direction and can rotate synchronously, and the second damping member 262 can rotate relative to the box body 21. The first damping member 261 and the second damping member 262 can be mutually sleeved together, and the torsion elastic element 263 is used to generate a damping torsion between the first damping member 261 and the second damping member 262. When the first damping member 261 rotates, it needs to overcome the damping torsion before the second damping member 262 can be driven to rotate. The direction of the damping torsion provided by the torsion elastic element 263 to the first damping member 261 is designed to be opposite to the unwinding rotation direction of the storage disk 23.

Specifically, in this embodiment, a plug hole 2330 may be formed in the storage reel 233, and the damping assembly 26 may be at least partially received in the plug hole 2330. The first damping member 261 is circumferentially fixed in the plug hole 2330, so that the first damping member 261 and the storage reel 233 do not rotate relative to each other. A damping chamber 2610 is formed in the first damping member 261, and the second damping member 262 is at least partially disposed in the damping chamber 2610. The torsion elastic element 263 may include a torsion spring, which may be disposed in the damping chamber 2610 and sleeved on the second damping member 262.

The first damping member 261 and the second damping member 262 are respectively formed with a mounting hole 2613 and a mounting hole 2624, and the two ends 2631 of the torsion spring are respectively inserted into the mounting hole 2613 and the mounting hole 2624. In some embodiments, the mounting hole 2613 and/or the mounting hole 2624 can be an arc-shaped hole, so that the end 2631 of the torsion spring has a certain movable space in the mounting hole 2613 and/or the mounting hole 2624, which can facilitate the assembly of the torsion spring. Of course, in other embodiments, the shape and size of the mounting hole 2613 and/or the mounting hole 2624 can also match the shape and size of the end 2631 of the torsion spring.

The second damping member 262 and the box body 21 can be plugged into each other. A damping medium 265, such as damping grease, can also be provided between the second damping member 262 and the box body 21. The damping medium 265 has a certain viscosity, and the viscosity of the damping medium 265 is used to hinder the movement of the second damping member 262, thereby obtaining a damping effect. When the second damping member 262 rotates relative to the box body 21, the damping medium 265 causes the second damping member 262 to generate a damping force T1 in the opposite direction of its rotation. The damping force T1 is designed to be greater than or equal to the damping torsion T2 formed between the first damping member 261 and the second damping member 262 through the torsion elastic element 263.

Specifically, one end of the second damping member 262 may be concavely formed with a damping hole 2620, and the box seat 211 may be protruding with a mounting shaft 2142 plugged into the damping hole 2620. The damping medium 265 may be filled between the outer wall of the mounting shaft 2142 and the cavity wall of the damping hole 2620.

In some embodiments, the first damping member 261 may have a first position and a second position relative to the second damping member 262. When the first damping member 261 is in the first position relative to the second damping member 262, the damping torque T2 formed between the first damping member 261 and the second damping member 262 through the torsion elastic element 263 is the largest, and at this time T2=T2max≤T1. When the first damping member 261 is in the second position relative to the second damping member 262, the damping torque T2 formed between the first damping member 261 and the second damping member 262 through the torsion elastic element 263 is the smallest, and at this time T2=T2 min＜T2max.

Specifically, the first damping member 261 includes a boss 2611, and the second damping member 262 includes a first limiting surface 2621 and a second limiting surface 2622 that are arranged opposite to each other in the circumferential direction, and a slideway 2623 for the boss 2611 to slide is formed between the first limiting surface 2621 and the second limiting surface 2622. When the boss 2611 abuts against the first limiting surface 2621, the first damping member 261 is in a first position relative to the second damping member 262. When the boss 2611 abuts against the second limiting surface 2622, the first damping member 261 is in a second position relative to the second damping member 262.

In this embodiment, the boss 2611 is located at one end of the first damping member 261 close to the box seat 211, which is more convenient for assembly and manufacturing. Of course, in other embodiments, the boss 2611 can also be set at other positions of the first damping member 261, for example, it can also be protruded and set at any position of the side wall of the first damping member 261 between its two axial ends.

The first damping member 261, the second damping member 262, the torsion elastic element 263, and the storage reel 233 can all be coaxially arranged. After the first damping member 261, the second damping member 262, and the torsion elastic element 263 are installed, the boss 2611 abuts against the second limiting surface 2622, so that the torsion elastic element 263 generates a damping torsion T2min on the first damping member 261. The damping torsion T2min can prevent the first damping member 261 and the second damping member 262 from shaking after the damping assembly 26 is assembled.

When the reducer 141 drives the storage tray 24 to rotate, and then drives the storage tray 23 to rotate through the medium conveyor belt 22, because T2 min＜T2max≤T1, the storage tray 23 will first drive the first damping member 261 to move from the second position to the first position, so that the boss 2611 abuts against the first limit surface 2621. The reducer 141 continues to move, and will drive the second damping member 262 to rotate through the first damping member 261. At this time, the reducer 141 needs to overcome the damping force T1, so that the medium conveyor belt 22 is always tightened by the damping force T1 during the movement. Here, the torque of the reducer 141 = κ* T1*(R1/R2) / η, where κ is the safety factor, η is the transmission efficiency of the reducer 141, R1 is the radius of the portion of the medium conveyor belt 22 wrapped around the storage tray 24, and R2 is the radius of the portion of the medium conveyor belt 22 wrapped around the storage tray 23.

When the reducer 141 stops moving, due to the restoring torque of the torsion elastic element 263, the torsion elastic element 263 will always generate a damping torque T2max on the first damping member 261, and then generate a damping torque T2max on the storage disk 23. In this way, the medium conveying belt 22 can be kept in a pre-tightened state even when it is not moving, and will not relax. In addition, even if the medium conveying belt 22 relaxes due to unexpected circumstances, under the action of the restoring torque of the torsion elastic element 263, the first damping member 261 can be rotated back to abut against the second limiting surface 2622, thereby driving the storage disk 23 to rotate and tightening the medium conveying belt 22.

The rotation angle between the first limiting surface 2621 and the second limiting surface 2622 (i.e., the angle between the first limiting surface 2621 and the second limiting surface 2622 in the circumferential direction of the second damping member 262) can range from 70° to 150°. Within this range, T2 min and T2max of appropriate sizes can be obtained, and the medium conveyor belt 22 can also obtain an appropriate retraction length.

In some embodiments, the damping assembly 26 may further include an elastic retaining ring 264, which may be sleeved on the second damping member 262 and used to limit the axial position of the first damping member 261 on the second damping member 262, so that the structure of the damping assembly 26 is stable and easy to assemble. One end of the second damping member 262 may extend out of the first damping member 261, and the portion of the second damping member 262 extending out of the first damping member 261 may be concave to form a slot 2625 for the elastic retaining ring 264 to be mounted.

In some embodiments, the aerosol generating article 20 may further include an atomizing seat 25, in which an atomizing chamber 250 is formed, and an inlet 251 and an outlet 252 are formed on the side wall of the atomizing seat 25, which are connected to the atomizing chamber 250. The medium conveying belt 22 can enter the atomizing chamber 250 through the inlet 251, and after being heated and atomized in the atomizing chamber 250, it can be transmitted through the outlet 252. One end of the heater 121 can extend into the atomizing chamber 250 to heat the medium conveying belt 22 entering the atomizing chamber 250.

In some embodiments, the atomizer seat 25 can be installed together with the box seat 211 in a detachable manner, and the atomizer seat 25 can be reused to reduce replacement costs. Of course, in its embodiments, the atomizer seat 25 can also be installed together with the box seat 211 in a non-detachable manner, or the atomizer seat 25 can also be integrally formed with the box seat 211.

In some embodiments, the cross-section of the inlet 251 and the outlet 252 (here, the cross-section perpendicular to the direction of travel of the medium conveyor belt 22) may be the same or similar to the cross-section of the medium conveyor belt 22 (here, the cross-section perpendicular to the direction of travel of the medium conveyor belt 22). In addition, a clearance fit may be adopted between the inlet 251, the outlet 252 and the medium conveyor belt 22, so that the medium conveyor belt 22 can move smoothly without getting stuck, and the edges of the inlet 251 and the outlet 252 can be prevented from scratching the medium conveyor belt 22. In addition, the annular gap 2510 formed between the periphery of the inlet 251 and the medium conveyor belt 22 and/or the annular gap 2520 formed between the periphery of the outlet 252 and the medium conveyor belt 22 can also be used as an airflow channel to connect the atomization chamber 250 with the receiving chamber 210, and then with the outside world.

It is understandable that the size of the annular gap 2510 and the annular gap 2520 should not be too small, otherwise it may cause excessive suction resistance, resulting in too low pressure in the atomizing chamber 250 and causing suction turbulence, affecting the suction experience. Of course, the size of the annular gap 2510 and the annular gap 2520 should not be too large, reducing or avoiding the leakage of the aerosol generated in the atomizing chamber 250 through the inlet 251 and the outlet 252.

Specifically, in the present embodiment, the atomizer seat 25 is arranged on the upper side of the box seat 211, and may include a main body 254 and an extension portion 255 extending upward from the main body 254. The main body 254 can be accommodated in the upper side of the cavity 210, the atomizer cavity 250 is formed in the main body 254, and the inlet 251 and the outlet 252 are respectively formed on the two opposite sides of the atomizer seat 25. An air outlet channel 253 connected to the atomizer cavity 250 is formed in the extension portion 255, and the lower end of the suction nozzle 30 is connected to the air outlet channel 253. The extension portion 255 can extend out of the box body 21, so as to facilitate mutual plug-in cooperation with the suction nozzle 30. A vent 2550 that connects the air outlet channel 253 with the outside world can also be formed on the side wall of the extension portion 255.

Of course, in other embodiments, the atomizer seat 25 may also be disposed at other positions of the box body 21. In addition, the configuration of the inlet 251 and the outlet 252 is not limited, for example, the inlet 251 and the outlet 252 may be disposed on the same side of the atomizer seat 25; or, the inlet 251 is disposed on one lateral side of the atomizer seat 25, and the outlet 252 is disposed on the bottom side of the atomizer seat 25.

In some embodiments, the aerosol generating article 20 may further include a guide structure 28 disposed in the cavity 210, which is used to guide the medium conveying belt 22 during its travel, to ensure smooth transmission of the medium conveying belt 22, and to ensure good contact between the medium conveying belt 22 and the heater 121. In some embodiments, the aerosol generating article 20 may include a plurality of guide structures 28, which are spaced apart on the transmission path of the medium conveying belt 22.

In some embodiments, the plurality of guide structures 28 may include a limiting roller 28a, a limiting roller 28b, and a limiting roller 28c sequentially distributed on the transmission path of the medium conveyor belt 22, and the rolling friction of each limiting roller ensures the smooth transmission of the medium conveyor belt 22. The medium conveyor belt 22 to be heated sequentially passes through the limiting roller 28a, the limiting roller 28b, and the inlet 251 into the atomizing chamber 250 for atomization, and the atomized medium conveyor belt 22 is output from the outlet 252 and then guided by the limiting roller 28c, and then rolled up on the storage tray 24. Of course, in other embodiments, the guide structure 28 may also include other structures such as convex ribs and convex columns.

The limiting roller 28a is arranged near the outlet 2141, so that the medium conveying belt 22 wound on the storage disk 23 can be smoothly transmitted, and the transmission of the medium conveying belt 22 is not affected by the change in the size of the medium conveying belt 22 wound on the storage disk 23. The limiting roller 28b and the limiting roller 28c are respectively arranged on two opposite sides of the atomizing seat 25, so as to make the medium conveying belt 22 in good contact with the heater 121. It should be noted that the limiting roller 28b and the limiting roller 28c are respectively arranged corresponding to the inlet 251 and the outlet 252. When the setting positions of the inlet 251 and the outlet 252 are changed, the setting positions of the limiting roller 28b and the limiting roller 28c can be changed accordingly.

Furthermore, a limiting roller 28d can be provided between the limiting roller 28c and the storage tray 24. The limiting roller 28d can increase the turning angle of the medium conveying belt 22 when passing through the limiting roller 28c, thereby improving the stratification problem caused by the atomized medium conveying belt 22 passing through the corner due to the small turning angle.

37-41 show an aerosol generating system 100 in a fifth embodiment of the present invention, wherein the aerosol generating system 100 comprises an aerosol generating device 10 and an aerosol generating product 20 that cooperate with each other. Among them, a substrate layer 222 is provided in the aerosol generating product 20. The aerosol generating device 10 comprises electronic components such as a battery, a heater 121, and a control circuit. The battery is used to power the heater 121, and the control circuit is used to control the heating work of the heater 121. After being powered on, the heater 121 can heat the substrate layer 222 in the aerosol generating product 20 in a contact or non-contact manner to generate an aerosol.

Furthermore, the aerosol generating system 100 may further include a nozzle 30, which may be mounted at one end of the aerosol generating product 20, and is used for the user to inhale the aerosol generated by the aerosol generating product 20 after atomization. In this embodiment, an air outlet channel 253 is formed at the upper end of the aerosol generating product 20. The nozzle 30 is cylindrical, and may be mounted in the air outlet channel 253 in a detachable or non-detachable manner. In other embodiments, the nozzle 30 is not limited to being cylindrical, and may also be a flat column or other shapes; of course, the nozzle 30 may also be mounted at one end of the aerosol generating device 10.

In this embodiment, the aerosol generating device 10 is substantially in the shape of a rectangular column, and a receiving chamber 1120 for receiving the aerosol generating product 20 is formed in the aerosol generating device 10. One end of the receiving chamber 1120 has a socket 1110 for the nozzle 30 to extend out. Of course, in other embodiments, the cross-sectional shape of the aerosol generating device 10 is not limited to being rectangular, and it may also be in other shapes such as a circle, a racetrack, or an ellipse.

The aerosol generating article 20 is detachably mounted in the accommodating chamber 1120. When the substrate layer 222 in the aerosol generating article 20 is used up, the substrate layer 222 can be updated by replacing the aerosol generating article 20. The aerosol generating device 10 is reusable, thereby reducing the use cost of the aerosol generating system 100.

As shown in FIGS. 38-41 , in some embodiments, the aerosol generating article 20 may include a box body 21 and a medium conveying belt 22 accommodated in the box body 21. A cavity 210 is formed in the box body 21, and the medium conveying belt 22 is accommodated in the cavity 210. The medium conveying belt 22 is in a belt shape as a whole and has a certain length, and a matrix layer 222 is distributed along the length direction of the medium conveying belt 22. The matrix layer 222 may include one or more atomizing media in solid and gel, which can generate aerosol after heating.

In some embodiments, the box body 21 is roughly in the shape of a rectangular parallelepiped, and may include a box seat 211 and a box cover 212 that cooperate with each other. The cavity 210 is formed between the box seat 211 and the box cover 212. Specifically, the cavity 210 may be formed by the depression of the box seat 211 or the box cover 212, or may be formed by the depression of the box seat 211 and the box cover 212. The box seat 211 and the box cover 212 may be connected together by one or more detachable or non-detachable methods such as threaded connection, snap connection, magnetic connection, and bonding.

In some embodiments, the box body 21 may be formed entirely or at least partially of a transparent material. The term "transparent" is used to describe a material that allows at least a significant proportion of incident light to pass through it, allowing for seeing through the material. In the present invention, a substantially transparent material may allow enough light to pass through it so that the media transport belt 22 within the box body 21 is visible.

The box body 21 may be completely transparent; alternatively, the box body 21 may have a lower level of transparency while still transmitting enough light to make the media conveyor belt 22 visible within the box body 21. Further, the box body 21 may include one or more areas formed of a transparent material so that a portion of the media conveyor belt 22 is visible through the one or more areas. In addition, the area formed of the transparent material may be colored, tinted, or colorless.

Of course, in other embodiments, the box body 21 may also be made of an opaque material. In other embodiments, the aerosol generating product 20 may not include the box body 21 , and the medium conveyor belt 22 may be directly installed in the aerosol generating device 10 .

The medium conveyor belt 22 can be arranged in the box body 21 in a winding manner. Specifically, a storage disk 23 and a receiving disk 24 can be arranged in the box body 21, and the unheated part of the medium conveyor belt 22 can be wound on the storage disk 23, and the heated part of the medium conveyor belt 22 can be wound on the receiving disk 24. The aerosol generating device 10 can push the medium conveyor belt 22 to unwind from the storage disk 23, and after being heated and atomized by the heater 121, it is wound up by the receiving disk 24. The winding arrangement enables more medium conveyor belts 22 to be stored in the box body 21, so that a single aerosol generating product 20 can be atomized and used multiple times, and the medium conveyor belt 22 before and after atomization is respectively wound on the storage disk 23 and the receiving disk 24, so as to avoid poor user experience such as odor crosstalk.

In some embodiments, the storage tray 23 may include a storage reel 233 and a storage bottom plate 231 and a storage tray cover 232 respectively disposed at both ends of the storage reel 233. The unheated portion of the medium conveying belt 22 may be wound on the storage reel 233, and the storage bottom plate 231 and the storage tray cover 232 may be used to prevent the medium conveying belt 22 from coming out during the winding process.

In some embodiments, both ends of the width of the medium conveyor belt 22 can also be respectively contacted and connected with the storage chassis 231 and the storage disk cover 232, which can make the movement of the medium conveyor belt 22 more stable, and can also complete the power transmission from the supply shaft 2331 to the storage chassis 231, the storage disk cover 232, and further to the medium conveyor belt 22 through the friction between the medium conveyor belt 22 and the storage chassis 231, the storage disk cover 232.

In other embodiments, the width of the medium conveyor belt 22 may also be smaller than the distance between the storage chassis 231 and the storage disk cover 232, so that the medium conveyor belt 22 has a certain floating space in the axial direction of the storage reel 233, and no friction is generated between the medium conveyor belt 22 and the storage chassis 231 and the storage disk cover 232, so that the medium conveyor belt 22 can move smoothly without getting stuck.

Of course, in other embodiments, the storage tray 23 may be provided with only one of the storage bottom tray 231 and the storage tray cover 232, or both ends may not be provided with the storage bottom tray 231 and the storage tray cover 232. The width limit of the medium conveying belt 22 at both ends can be achieved by the box body 21.

Similarly, the storage tray 24 may also include a storage reel 243 and a storage bottom plate and a storage tray cover 242 respectively disposed at both ends of the storage reel 243. The heated portion of the medium conveying belt 22 may be wound on the storage reel 243, and the storage bottom plate and the storage tray cover 242 may be used to prevent the medium conveying belt 22 from coming out during the winding process.

In some embodiments, both ends of the width of the medium conveyor belt 22 can also be respectively contacted and connected with the storage chassis and the storage tray cover 242, which can make the movement of the medium conveyor belt 22 more stable, and can also complete the transmission of power from the storage shaft 241 to the storage chassis and the storage tray cover 242, and further to the medium conveyor belt 22 through the friction between the medium conveyor belt 22 and the storage chassis and the storage tray cover 242.

In other embodiments, the width of the medium conveyor belt 22 may also be smaller than the distance between the storage chassis and the storage tray cover 242, so that the medium conveyor belt 22 has a certain floating space in the axial direction of the storage reel 243, and no friction is generated between the medium conveyor belt 22 and the storage chassis and the storage tray cover 242, so that the medium conveyor belt 22 can move smoothly without getting stuck.

Of course, in other embodiments, the storage tray may be provided with only one of the storage bottom tray and the storage tray cover 242, or both ends may not be provided with the storage bottom tray or the storage tray cover 242. The width limit of the medium conveying belt 22 at both ends may be achieved by the box body 21.

In some embodiments, one of the storage tray 23 and the receiving tray 24 is a driving wheel, and the other is a driven wheel. For example, the receiving tray 24 is the driving wheel and the storage tray 23 is the driven wheel. Under the action of an external driving force, the receiving tray 24 rotates to reel in the medium conveying belt 22, thereby driving the storage tray 23 to rotate synchronously to unwind the medium conveying belt 22. In other embodiments, the storage tray 23 and the receiving tray 24 may also be driving wheels. In other embodiments, the storage tray 23 and the receiving tray 24 may also rotate asynchronously. For example, the storage tray 23 first unwinds a section of the medium conveying belt 22, and after heating is completed, the receiving tray 24 is driven to rotate for rewinding.

In some embodiments, the medium conveying belt 22 may include a base belt 221 and a matrix layer 222 disposed on the base belt 221. The base belt 221 is used to carry the matrix layer 222. The base belt 221 has a first surface 2211 and a second surface 2212 disposed opposite to each other in the thickness direction. When the medium conveying belt 22 is wound on the storage reel 233, the second surface 2212 of the base belt 221 may face the storage reel 233, and the first surface 2211 of the base belt 221 may be relatively far away from the storage reel 233. The matrix layer 222 may be disposed on the first surface 2211 and/or the second surface 2212 of the base belt 221 by coating, lamination or bonding. In addition, the matrix layer 222 may be distributed continuously on the base belt 221, or may be distributed at intervals in different regions.

Specifically, in this embodiment, the matrix layer 222 is disposed on the first surface 2211 of the base tape 221. Of course, in other embodiments, the matrix layer 222 may also be disposed on the second surface 2212 of the base tape 221, or disposed on both the first surface 2211 and the second surface 2212 of the base tape 221.

Furthermore, the base belt 221 may be made of a heat-conducting material, such as a heat-conducting metal material such as aluminum foil or copper foil. Of course, the base belt 221 may also be made of a heat-conducting non-metallic material, such as graphite. In other embodiments, the medium conveyor belt 22 may also be made entirely of the matrix layer 222, that is, the medium conveyor belt 22 does not include the base belt 221.

In addition, in this embodiment, the heater 121 adopts a resistive heating method, and the heater 121 generates heat through the Joule effect, thereby transferring the heat to the medium conveyor belt 22 for baking and heating. In terms of implementation, the heater 121 and the medium conveyor belt 22 can be in direct physical contact to achieve heat conduction, and the heater 121 and the medium conveyor belt 22 can also achieve heat transfer from the heater 121 to the medium conveyor belt 22 through indirect contact methods such as heat radiation.

Furthermore, the heater 121 can contact the side of the medium conveyor belt 22 where the matrix layer 222 is not provided, and transfer heat to the matrix layer 222 through the base belt 221. In this way, it can be avoided that the heated matrix layer 222 adheres to the heater 121 and affects the heating effect of the heater 121.

Of course, in other embodiments, the heater 121 may also be in direct contact with the matrix layer 222, which is beneficial to improving the heat transfer efficiency and reducing heat loss. In this case, the medium conveyor belt 22 may not need to be made of a heat-conducting material. In other embodiments, the heater 121 may also use other heating methods such as electromagnetic heating, infrared radiation, ultrasound, microwave, plasma, etc.

In some embodiments, an atomizing seat 25 may be further provided in the box body 21, an atomizing chamber 250 is formed in the atomizing seat 25, and an inlet 251 and an outlet 252 are formed on the side wall of the atomizing seat 25, which are connected to the atomizing chamber 250. The medium conveying belt 22 can enter the atomizing chamber 250 through the inlet 251, and after being heated and atomized in the atomizing chamber 250, it can be transmitted through the outlet 252. One end of the heater 121 can extend into the atomizing chamber 250 to heat the medium conveying belt 22 entering the atomizing chamber 250.

The cross-section of the inlet 251 and the outlet 252 (here, the cross-section perpendicular to the direction of travel of the medium conveyor belt 22) is the same or similar to the cross-section of the medium conveyor belt 22 (here, the cross-section perpendicular to the direction of travel of the medium conveyor belt 22), and the inlet 251 and the outlet 252 can be fitted with a gap to avoid scratching the medium conveyor belt 22. Of course, the gap between the inlet 251 and the outlet 252 and the medium conveyor belt 22 is not too large to reduce or avoid leakage of the aerosol generated in the atomization chamber 250 through the inlet 251 and the outlet 252.

Specifically, in the present embodiment, the atomizer seat 25 is arranged on the upper side of the cavity 210, and the atomizer chamber 250 is directly connected to the lower end of the air outlet channel 253, so that the output path of the aerosol is shorter. The inlet 251 and the outlet 252 are respectively formed on two opposite sides of the atomizer seat 25 in the lateral direction. Of course, in other embodiments, the atomizer seat 25 can also be arranged at other positions of the cavity 210, and the atomizer chamber 250 can also be indirectly connected to the air outlet channel 253. In addition, the arrangement of the inlet 251 and the outlet 252 is also not limited. For example, the inlet 251 and the outlet 252 can be arranged on the same side of the atomizer seat 25; or, the inlet 251 is arranged on one side of the atomizer seat 25 in the lateral direction, and the outlet 252 is arranged on the bottom side of the atomizer seat 25.

In some embodiments, a guide structure 28 may be further provided in the box body 21 for guiding the medium conveying belt 22 during its travel and ensuring good contact between the medium conveying belt 22 and the heater 121. In this embodiment, there may be a plurality of guide structures 28, which are spaced apart on the transmission path of the medium conveying belt 22. Each guide structure 28 may be a rotatable structure, such as a guide roller or a wheel; of course, it is understandable that in other embodiments, each guide structure 28 may also be a non-rotatable structure, such as a guide column or other structure fixedly provided in the box body 21.

In the present embodiment, each guide structure 28 is a guide roller. Further, the plurality of guide structures 28 include two guide rollers 28e and 28f, which are respectively arranged on two opposite sides of the atomizing seat 25 in the lateral direction, and are used to make the medium conveying belt 22 in good contact with the heater 121. The medium conveying belt 22 to be heated enters the atomizing chamber 250 along the guide rollers 28e and the inlet 251 for atomization, and the atomized medium conveying belt 22 is output from the outlet 252 and then guided by the guide roller 28f, and then rolled up on the storage tray 24. It should be noted that the two guide rollers 28e and 28f are respectively arranged corresponding to the inlet 251 and the outlet 252. When the setting positions of the inlet 251 and the outlet 252 are changed, the two guide rollers 28e and 28f can be changed accordingly.

In some embodiments, a driving shaft 27 is further provided in the box body 21, and the driving shaft 27 rotates to push the medium conveying belt 22 to unwind from the storage tray 23 and be heated and atomized by the heater 121. The driving shaft 27 can be arranged on the travel path of the medium conveying belt 22 between the heater 121 and the storage tray 24, and further, between the travel path between the guide roller 28f and the storage tray 24. The driving shaft 27 can have a cam or a cam-like structure, so that the driving shaft 27 can change the path length of the medium conveying belt 22 between the heater 121 and the storage tray 24 during the rotation process.

As shown in FIG. 42 , in some embodiments, a through hole 270 may be formed on the driving shaft 27, and the medium conveying belt 22 coming out of the outlet 252 passes through the through hole 270 and is then reeled onto the receiving tray 24. This structure allows the medium conveying belt 22 to be wound around the driving shaft 27 during the rotation of the driving shaft 27, which can increase the stretching length of the medium conveying belt 22 each time the driving shaft 27 rotates. At the same time, the driving shaft 27 has the function of temporarily reeling in the medium conveying belt 22 to prevent the medium conveying belt 22 from being loosened.

Specifically, in this embodiment, the driving shaft 27 includes two rotating shafts 271 arranged at intervals, the diameters of the two rotating shafts 271 may be equal or unequal, and the interval between the two rotating shafts 271 forms a through hole 270. The two rotating shafts 271 are arranged in parallel and at intervals, and the rotation center line of the driving shaft 27 may coincide with the central axis of one of the rotating shafts 271. Of course, in other embodiments, the rotation center line of the driving shaft 27 may also be parallel to the central axes of the two rotating shafts 271 but not coincident.

Furthermore, the driving shaft 27 may further include two spaced connection plates 272 . The two connection plates 272 are respectively disposed at two ends of the shaft 271 and may be used to limit the medium conveying belt 22 .

As shown in Figure 39, when the driving shaft 27 is in the first rotation position, the medium conveying belt 22 can pass through the opening 270 between the two shafts 271 and is not wrapped around the two shafts 271. At this time, the medium conveying belt 22 has the shortest path length between the heater 121 and the storage tray 24.

As shown in FIG40 , when the driving shaft 27 is in the second rotation position, the medium conveying belt 22 coming out of the guide roller 28f passes through a shaft 271 farther from the guide roller 28f, passes through the opening 270, and then passes through a shaft 271 closer to the guide roller 28f and is wound on the storage tray 24. At this time, the medium conveying belt 22 has the longest path length between the heater 121 and the storage tray 24. The structure of the driving shaft 27 enables the medium conveying belt 22 to have a longer stretching length each time, and the stretching length is close to the sum of the circumferences of the two shafts 271.

When the driving shaft 27 rotates in a clockwise direction (or counterclockwise direction in other embodiments) from the first rotation position shown in FIG. 39 to the second rotation position shown in FIG. 40, the medium conveying belt 22 can be pushed to unwind from the storage disk 23, and the speed of the medium conveying belt 22 unwound from the storage disk 23 is consistent each time the driving shaft 27 rotates, so that the length of the medium conveying belt 22 unwound from the storage disk 23 is consistent each time the driving shaft 27 rotates one cycle. When the driving shaft 27 rotates in a counterclockwise direction (or clockwise direction in other embodiments) from the second rotation position shown in FIG. 40 to the first rotation position shown in FIG. 39, the driving shaft 27 unwinds the medium conveying belt 22 wound thereon, and rewinds it by rotating the storage disk 24.

Furthermore, an airflow sensor 218 may be provided in the box body 21, and the airflow sensor 218 may be connected to the atomizing chamber 250 via the inlet 251 or the outlet 252. When the suction nozzle 30 has a suction action, the airflow sensor 218 can sense the change of airflow or air pressure, and the control circuit can start the battery to power the heater 121 according to the signal of the airflow sensor 218 to start the atomization work. Of course, in other embodiments, the airflow sensor 218 may also be provided in the aerosol generating device 10. In other embodiments, the airflow sensor 218 may not be provided in the aerosol generating system 100.

As shown in FIGS. 37, 38, and 43, the aerosol generating device 10 may include a body 11 and a battery, a heater 121, a control circuit, a drive assembly 14, and a transmission assembly 150 contained in the body 11. The battery is electrically connected to the heater 121 and the drive assembly 14, respectively, for providing electrical energy to the heater 121 and the drive assembly 14. The control circuit is electrically connected to the heater 121 and the drive assembly 14, respectively, for controlling the operation of the heater 121 and the drive assembly 14. In some embodiments, a bracket 155 may also be provided in the body 11, and the bracket 155 may be used for supporting and installing the drive assembly 14 and the transmission assembly 150.

The body 11 may include a frame 112, and a cover 111 and a base 113 respectively matched with the frame 112. The cover 111 and the base 113 may be respectively covered on both sides of the frame 112 in the thickness direction. A receiving cavity 1120 for receiving the aerosol generating product 20 is formed between the cover 111 and the frame 112. The cover 111 and the frame 112 may be connected together in a detachable manner such as a snap connection, a threaded connection, a magnetic connection, etc., so that the aerosol generating product 20 can be taken out and replaced by opening the cover 111.

In this embodiment, a plurality of magnets 114 are embedded on the side of the cover 111 facing the frame 112, and a plurality of magnets 115 are embedded on the side of the frame 112 facing the cover 111 corresponding to the plurality of magnets 114, so that the cover 111 and the frame 112 are magnetically fixed to each other through the magnets 114 and 115.

An installation cavity 1130 is formed between the base 113 and the frame 112, and the drive assembly 14 and the transmission assembly 150 can be accommodated in the installation cavity 1130. The base 113 and the frame 112 can be connected together in a detachable manner, which is convenient for repairing, replacing or upgrading the components in the installation cavity 1130. Of course, the base 113 and the frame 112 can also be connected together in a non-detachable manner to prevent the user from accidentally opening the installation cavity 1130 and causing damage to the components.

In this embodiment, the frame 112 has a greater thickness than the cover 111 and the base 113, and at least most of the accommodating cavity 1120 and the installation cavity 1130 are formed by the depression of the frame 112. Of course, in other embodiments, the specific structure of the body 11 is not limited to the above specific embodiment.

The bottom wall of the accommodating cavity 1120 (i.e., a side wall disposed opposite to the cover body 111) may be further recessed to form an installation cavity 1121 for the installation and fixation of the heater 121. One end of the heater 121 may be directly or indirectly inserted into the installation cavity 1121 for fixation, and the other end may extend out of the installation cavity 1121 and may be inserted into the atomizing cavity 250, for heating the matrix layer 222 entering the atomizing cavity 250 after power is turned on. In some embodiments, the heater 121 may be in the form of a sheet, so as to facilitate full contact with the belt-shaped medium conveyor belt 22, so as to fully heat the matrix layer 222 on the medium conveyor belt 22 by heat conduction. Of course, in other embodiments, the heater 121 is not limited to being in the form of a sheet, and may also be in other shapes such as a columnar shape; in addition, the heater 121 may also be disposed at other positions of the body 11.

Furthermore, the aerosol generating device 10 may also include a mounting seat 122 accommodated in the mounting cavity 1121. In some embodiments, the mounting seat 122 may be made of high temperature resistant materials such as ceramic or PEEK (polyetheretherketone). One end of the heater 121 may be inserted into the mounting seat 122 and fixed in the mounting cavity 1121 via the mounting seat 122, which can reduce the heat transferred from the heater 121 to the cavity wall of the mounting cavity 1121, and facilitate heat insulation.

The drive assembly 14 is used to provide a driving force for the medium conveyor belt 22 to travel. The transmission assembly 150 is connected to the drive assembly 14, and is used to transmit the driving force of the drive assembly 14 to the aerosol generating article 20. In this embodiment, the drive assembly 14 is an electric drive structure, which may include a reducer 141 and an output shaft 142 connected to the reducer 141. Of course, in other embodiments, the drive assembly 14 may also include other electric drive structures such as a motor. In other embodiments, the drive assembly 14 is also not limited to an electric drive structure, and it may also be a manual drive structure, such as a handle or a hand wheel.

The transmission assembly 150 may include a driving gear 151, an unwinding gear 152, and a receiving gear 154. The driving gear 151 is connected to the output shaft 142 of the reducer 141, and can rotate synchronously with the output shaft 142 under the drive of the reducer 141. The unwinding gear 152 can be directly or indirectly meshed with the driving gear 151 to provide power for the medium conveying belt 22 to pass through the heater 121. The receiving gear 154 can be directly or indirectly meshed with the driving gear 151 to provide power for the winding of the medium conveying belt 22.

In some embodiments, the driving gear 151 can rotate in a first direction or a second direction opposite to the first direction under the drive of the reducer 141. In this embodiment, the first direction is counterclockwise and the second direction is clockwise; in other embodiments, the first direction may be clockwise and the second direction may be counterclockwise. When the driving gear 151 rotates in the first direction, the unwinding gear 152 rotates to push the medium conveying belt 22 to pass through the heater 121.

In this embodiment, the storage gear 154 is configured to be engaged or disengaged with the driving gear 151 according to the rotation direction of the driving gear 151. In some embodiments, the transmission assembly 150 further includes a transfer gear 153, and the driving gear 151 and the storage gear 154 are engaged or disengaged through the transfer gear 153. Specifically, the transfer gear 153 may have a first position separated from the storage gear 154 and a second position engaged with the storage gear 154. In this embodiment, the relative position between the storage gear 154 and the transfer gear 153 can be adjusted by the forward and reverse rotation of the reducer 141 and the driving gear 151. When the driving gear 151 rotates in the first direction, the driving gear 151 can drive the transfer gear 153 to move to the first position where the transfer gear 153 is disengaged from the storage gear 154. When the driving gear 151 rotates in the second direction, the driving gear 151 can drive the transfer gear 153 to move to the second position where the transfer gear 153 is engaged with the storage gear 154. When the driving gear 151 rotates in the first direction or the second direction, the transfer gear 153 always keeps meshing with the driving gear 151. Of course, in other embodiments, the relative position between the storage gear 154 and the transfer gear 153 can also be achieved by manual operation.

The frame 112 may also be formed with a slide groove 1131 for slidingly installing the transfer gear 153. One end of the transfer gear 153 has a gear shaft 1531, and the gear shaft 1531 can be slidably installed in the slide groove 1131. Specifically, in the present embodiment, the slide groove 1131 is in the shape of a runway, and the gear shaft 1531 can slide back and forth in the length direction of the slide groove 1131, so that the transfer gear 153 can be smoothly switched between the first position and the second position. It can be understood that in other embodiments, the specific shape of the slide groove 1131 is not limited, for example, it can also be in other shapes such as an ellipse or a rectangle. In addition, the setting position of the slide groove 1131 is also not limited, for example, the slide groove 1131 can also be formed on the bracket 155.

In this embodiment, the bracket 155 is generally plate-shaped. The driving gear 151, the unwinding gear 152, the transfer gear 153, and the storage gear 154 are all arranged on the side of the bracket 155 facing the aerosol generating product 20, so as to facilitate connection with the aerosol generating product 20. The reducer 141 is arranged on the side of the bracket 155 away from the aerosol generating product 20, and the output shaft 142 passes through the bracket 155 to be connected with the driving gear 151.

One end of the storage gear 154 has an output shaft 1541, and the output shaft 1541 is connected to the storage reel 243 of the storage tray 24 and can drive the storage reel 243 to rotate synchronously. In some embodiments, the output shaft 1541 and the storage reel 243 can be connected together by mutual sleeve connection, and the output shaft 1541 and the storage reel 243 have a non-circular cross-section such as a D-shape, a quadrilateral, a polygon, an ellipse, etc., so that the output shaft 1541 and the storage reel 243 can rotate synchronously, and the output shaft 1541 and the storage reel 243 are easy to disassemble and assemble.

One end of the unwinding gear 152 has an output shaft 1521, which is connected to the driving shaft 27 and can drive the driving shaft 27 to rotate synchronously. In some embodiments, the rotation center line of the output shaft 1521 coincides with the rotation center line of one of the shafts 271 in the driving shaft 27. Of course, in other embodiments, the rotation center line of the output shaft 1521 may not coincide with the rotation center line of each shaft 271. The output shaft 1521 and the driving shaft 27 can be connected together by mutual sleeve connection, and the output shaft 1521 has a non-circular cross-section such as a D-shape, a quadrilateral, a polygon, an ellipse, etc., so that the output shaft 1521 and the driving shaft 27 can rotate synchronously, and the output shaft 1521 and the driving shaft 27 are easy to disassemble and assemble.

As shown in FIG. 44 , in one embodiment, when the driving gear 151 rotates in a first direction (counterclockwise in the example), a force F can be applied to the transfer gear 153, and the force F can cause the transfer gear 153 to slide from the second position to the first position and remain in the first position. At this time, the storage gear 154 is disengaged from the transfer gear 153, and the storage gear 154 will not be driven to rotate by the transfer gear 153, and the storage tray 24 will not be stored. Driven by the driving gear 151, the unwinding gear 152 rotates synchronously with the driving gear 151 in the opposite direction (clockwise in the example), thereby driving the driving shaft 27 to rotate in the clockwise direction, pushing the medium conveyor belt 22 to transmit and pass through the heater 121.

As shown in FIG. 45 , after heating is completed, the control circuit controls the driving gear 151 to rotate in the second direction (clockwise in the example), thereby applying a force F' opposite to the force F to the transfer gear 153, and the force F' can make the transfer gear 153 slide from the first position to the second position and remain in the second position. At this time, the unwinding gear 152 rotates synchronously with the driving gear 151 in the opposite direction (counterclockwise in the example) under the drive of the driving gear 151, thereby driving the driving shaft 27 to rotate in the counterclockwise direction, thereby unwinding the portion of the medium conveying belt 22 wound on the driving shaft 27. At the same time, the transfer gear 153 rotates with the driving gear 151 in the counterclockwise direction under the drive of the driving gear 151, thereby driving the storage gear 154 meshing with the transfer gear 153 to rotate in the clockwise direction, thereby driving the storage tray 24 to rotate in the clockwise direction, thereby winding the medium conveying belt 22.

In this embodiment, the transmission of the medium conveyor belt 22 is promoted by the rotation of the driving shaft 27, so that the length of the medium conveyor belt 22 that moves each time the driving shaft 27 rotates can be ensured to be consistent. The unwinding and storage actions of the medium conveyor belt 22 are achieved by the forward and reverse rotation of the reducer 141 and the driving gear 151, and the relative position between the storage gear 154 and the transfer gear 153 is adjusted by the forward and reverse rotation of the reducer 141 and the driving gear 151, with a high degree of automation and high control accuracy.

As shown in FIG. 43 , in some embodiments, the aerosol generating device 10 may further include a position detection component 16, which may include a potentiometer 161. The potentiometer 161 can detect the rotation angle of the storage gear 154 and feed it back to the control circuit. The potentiometer 161 and the storage gear 154 can be coaxially arranged, and the potentiometer 161 can rotate synchronously with the storage gear 154. Specifically, the detection shaft 162 of the potentiometer 161 can pass through the bracket 155 and be plugged and fixed with the storage gear 154, so that it can rotate synchronously with the storage gear 154 under the drive of the storage gear 154. Of course, in other embodiments, the position detection component 16 is not limited to the potentiometer 161, and other known position sensors can also be used; in addition, the position detection component 16 can also accurately control the operation of the reducer 141 by detecting the rotation angle of other gears such as the storage gear 154.

46 shows an aerosol generating system 100 in a sixth embodiment of the present invention, and the aerosol generating system 100 may include a housing 101, a belt-shaped medium conveyor belt 22, and a transmission device 40. The belt-shaped medium conveyor belt 22 is movably disposed in the housing 101, and the transmission device 40 is disposed in the housing 101 and cooperates with the belt-shaped medium conveyor belt 22 to provide power to the belt-shaped medium conveyor belt 22. In some embodiments, the belt-shaped medium conveyor belt 22 may be in the shape of a flat belt, but is not limited to it, and may be made of a tin foil belt with a solid aerosol generating matrix arranged on the surface.

In some embodiments, the aerosol generating system 100 may further include a first reel structure 102 for winding an unheated strip-shaped medium conveying belt 22, a second reel structure 103 for winding a heated strip-shaped medium conveying belt 22, and a heating structure 12 for locally heating the strip-shaped medium conveying belt 22. The transmission device 40 can accurately transmit the strip-shaped medium conveying belt 22, so that more atomization times are available, and the regions of the strip-shaped medium conveying belt 22 atomized each time will not be mixed together, so that the taste is good and the user experience is improved.

Specifically, after a portion of the strip-shaped medium conveyor belt 22 is heated, the portion of the strip-shaped medium conveyor belt 22 that has been heated is wound and collected by the second reel structure 103, and the first reel structure 102 releases the unheated strip-shaped medium conveyor belt 22, so that different positions of the strip-shaped medium conveyor belt 22 can be heated. In some embodiments, the transmission device 40 can be disposed on the transmission path between the first reel structure 102 and the heating structure 104 to transmit the corresponding strip-shaped medium conveyor belt 22 to the heating structure 12 for heating.

The aerosol generating system 100 can prevent the occurrence of undesirable situations such as odor crosstalk by collecting and storing the heated portion of the belt-shaped medium conveyor belt 22 and the unheated portion of the belt-shaped medium conveyor belt 22 separately, thereby improving the user experience.

In some embodiments, the first reel structure 102 and the second reel structure 103 may respectively include a chassis 1021 disposed in the shell 101, a reel 1022 disposed on the chassis 1021, and a cover body 1023 disposed on the reel 1022 and matched with the chassis 1021, wherein the cover body 1023 and the chassis 1021 may be relatively disposed at the two ends of the reel 1022, thereby forming a second receiving space for accommodating the wound and collected belt medium conveyor belt 22.

FIG. 47 and FIG. 48 show a transmission device 40 in one embodiment of the present invention, which is used to transmit a strip-shaped medium conveyor belt 22, and may include a locking component 41 and a driving component 46. The locking component 41 has a locking state relatively fixed with the strip-shaped medium conveyor belt 22 and an unlocking state relatively separated or loosely contacted with the strip-shaped medium conveyor belt 22. The driving component 46 is connected to the locking component 41 to drive the locking component 41 to move along the first direction B1 (horizontal direction in the figure). When the locking component 41 is in the locked state, it can be relatively fixed with the strip-shaped medium conveyor belt 22, so as to drive the strip-shaped aerosol generating substrate to move; when the locking component is in the unlocked state, it can return to the initial position, and so on, to achieve continuous conveyance of the strip-shaped medium conveyor belt 22 until the entire strip-shaped medium conveyor belt 22 is heated.

Referring to FIGS. 48 to 50 together, the locking assembly 41 in some embodiments includes at least one clamping member 411, which can move back and forth along a second direction B2 (vertical direction in the figure) intersecting the first direction B1 to switch back and forth between the locking state and the unlocking state of the locking assembly 41. Specifically, the at least one clamping member 411 can move toward the belt-shaped medium conveying belt 22 to clamp the belt-shaped medium conveying belt 22 to achieve the above-mentioned locking state, and move away from the belt-shaped medium conveying belt 22 to achieve the above-mentioned unlocking state.

When the locking assembly 41 is in an unlocked state, the locking assembly 41 is in a relatively separated or loosely contacted unlocked state with the belt-shaped medium conveying belt 22. At this time, even if the locking assembly 41 moves, it will not drive the belt-shaped medium conveying belt 22 to move synchronously. Here, relative separation means that the locking assembly 41 is not in contact with the belt-shaped medium conveying belt 22; loose contact means that the locking assembly 41 is in contact with the belt-shaped medium conveying belt 22, but the locking assembly 41 cannot drive the belt-shaped medium conveying belt 22 to move when moving along the first direction B1. Preferably, when the locking assembly 41 is in an unlocked state, the locking assembly 41 is not in contact with the belt-shaped medium conveying belt 22, that is, the distance between the two clamping members 411 is greater than the thickness of the belt-shaped medium conveying belt 22.

In some embodiments, the second direction B2 is arranged perpendicular to the first direction B1 so that the at least one clamping member can move back and forth along a direction perpendicular to the first direction B1 to achieve vertical clamping of the belt-shaped medium conveyor belt 22 with better effect.

In some embodiments, the locking assembly 41 may include two clamping members 411, and the two clamping members 411 may be moved closer to and farther from each other along the second direction B2. When the two clamping members 411 are moved closer to each other along the second direction B2, the belt-shaped medium conveying belt 22 may be clamped from two opposite sides of the belt-shaped medium conveying belt 22. When the two clamping members 411 are moved away from each other along the second direction B2, the clamping of the belt-shaped medium conveying belt 22 may be released. In some embodiments, one of the two clamping members 411 may be movable and the other may not be movable, and the purpose of clamping the belt-shaped medium conveying belt 22 may also be achieved.

In some embodiments, the two clamping members 411 may be block-shaped, and each clamping member 411 has a clamping surface 4111, which is a surface of the corresponding clamping member 411 facing the other clamping member 411. The two clamping members 411 are respectively in contact with two opposite surfaces of the strip-shaped medium conveying belt 22 through their clamping surfaces 4111. In some embodiments, the clamping surfaces 4111 of the two clamping members 411 are opposite to each other, and the shapes and sizes of the two clamping members 411 are the same, so that the strip-shaped medium conveying belt 22 can be clamped more securely, and the stress concentration caused by insufficient alignment can be prevented from causing damage to the strip-shaped medium conveying belt 22. In some embodiments, the width and length of the clamping surface 4111 can be equivalent to the width of the strip-shaped medium conveying belt 22. Specifically, the width of the clamping surface 4111 can be equal to, slightly larger than, or slightly smaller than the width of the strip-shaped medium conveying belt 22.

In other embodiments, the clamping surface 4111 may also be set in a circular shape, and the diameter of the circular clamping surface 4111 may be equivalent to the width of the belt-shaped medium conveyor belt 22, that is, the diameter of the clamping surface 4111 may be equal to, slightly larger than, or slightly smaller than the width of the belt-shaped medium conveyor belt 22.

In some embodiments, the clamping member 411 may be made of an elastic material, or at least the clamping surface 4111 of the clamping member 411 may be formed of an elastic material. In this way, the clamping member 411 and the strip-shaped medium conveying belt 22 are more gently abutted, which can increase friction on one hand, and prevent the clamping surface 4111 of the clamping member 411 from being too hard and damaging the strip-shaped medium conveying belt 22 on the other hand. Of course, the clamping member 411 is not limited to being made of the above materials. For some strip-shaped medium conveying belts 22 with relatively high structural strength, the clamping member 411 may also be made of a completely rigid material.

As shown in Figures 48 to 50, the locking assembly 41 in some embodiments further includes at least one pusher 413, which is connected to the drive assembly 46 and is used to drive at least one clamping member 411 to move to a locked state and remain in the locked state. It can also be said that the locking assembly 41 in some embodiments further includes a pusher 413 connected to the drive assembly 46, which is used to provide at least one driving force for the at least one clamping member 411 to move along the second direction B2. Specifically, one end of the pusher 413 is connected to the drive assembly 46, and the other end is connected to the at least one clamping member 411.

As shown in the figure, the locking assembly 41 further includes at least one elastic member 412, which is connected to at least one clamping member and is used to drive at least one clamping member 411 to move to an unlocked state and maintain it in the unlocked state. It can also be said that the locking assembly 41 in some embodiments may also include an elastic member 412, which is used to provide at least one elastic reset force to the at least one clamping member 411, and the direction of the at least one elastic reset force is opposite to the direction of the at least one driving force.

Thus, when the at least one elastic restoring force is used to drive the at least one clamping member 411 away from the belt-shaped medium conveying belt 22, the at least one driving force is used to drive the at least one clamping member 411 closer to the belt-shaped medium conveying belt 22. Conversely, when the at least one elastic restoring force is used to drive the at least one clamping member 411 closer to the belt-shaped medium conveying belt 22, the at least one driving force is used to drive the at least one clamping member 411 away from the belt-shaped medium conveying belt 22.

In some embodiments, when the locking assembly 41 includes two clamping members 411 that can move toward and away from each other, the pushing member 413 provides a pushing force to each clamping member 411, and the pushing forces provided by the pushing member 413 to the two clamping members 411 are in opposite directions (away from each other or toward each other) to push the two clamping members 411 away from or closer to each other. At this time, the elastic member 412 provides two elastic reset forces in opposite directions to the two clamping members 411. The setting of the elastic member 412 allows the two clamping members 411 to be elastically maintained in an unlocked state. When the pushing forces applied by the pushing member 413 to the two clamping members 411 are respectively greater than the corresponding elastic reset forces, the two clamping members 411 will be driven together until the belt medium conveyor belt 22 is clamped.

In the illustrated embodiment, the elastic member 412 may be disposed between the two clamping members 411 to provide an elastic restoring force for the two clamping members 411 to move away from each other. In other embodiments, the elastic member 412 may include two elastic units, which are respectively disposed at opposite ends of the two clamping members 411 to provide an elastic restoring force for the two clamping members 411 to move closer to each other.

In some embodiments, at least one pusher 413 is configured to move along the first direction B1 to drive at least one clamping member 411 to move along the second direction B2 to the locked state, and when at least one clamping member 411 is in the locked state, the locking assembly 41 is driven to move along the first direction B1. In other words, the pusher 413 can be arranged to move back and forth along the first direction B1, and can be operably matched with the at least one clamping member 411 to provide the at least one driving force mentioned above.

Specifically, when the locking assembly 41 is in the unlocked state, the pushing member 413 can be out of contact with the at least one clamping member 411. When the strip-shaped medium conveying belt 22 needs to be clamped, the pushing member 413 moves toward the at least one clamping member 411 along the first direction B1 until it contacts the at least one clamping member 411, and further gradually increases the strength of at least one pushing force provided to the at least one clamping member 411 until the corresponding elastic reset force is overcome, thereby resolving the locking of the at least one clamping member 411 corresponding to the strip-shaped medium conveying belt 22.

In some embodiments, at least one clamping member 411 includes at least one first mating slope 4112, and at least one pushing member 413 includes at least one second mating slope 4130. The at least one second mating slope 4130 pushes against the at least one first mating slope 4112, so that the at least one clamping member 411 moves along the second direction B2 to a locked state. In other words, at least one wedge-shaped mating structure is provided between the pushing member 413 and the at least one clamping member 411, and the at least one wedge-shaped mating structure decomposes the driving force of the pushing member 413 along the first direction B1 into the at least one driving force mentioned above.

As shown in Figures 52 and 53, in some embodiments, the at least one wedge-shaped mating structure may include a first mating bevel 4112 formed on the at least one clamping member 411 and at least one second mating bevel 4130 formed on the pushing member 413, and the first mating bevel 4112 cooperates with the at least one second mating bevel 4130 to achieve the decomposition of the driving force.

Specifically, when the first mating bevel 4112 and the second mating bevel 4130 are in contact, the clamping member 411 is pushed by the pushing member 413 and moves along the second direction B2. The first mating bevel 4112 and the at least one second mating bevel 4130 can be inclined planes or arc surfaces. The pushing member 413 cooperates with the first mating bevel 4112 through the second mating bevel 4130 to provide the movable clamping member 411 with a pushing force in the opposite direction to the elastic reset force to which the clamping member 411 itself is subjected, so that the pushing member 413 changes the state of the locking assembly 41 by cooperating with the clamping member 411.

As shown in Figure 49 again, in some embodiments, the pushing member 413 may include a pair of force-applying portions 4131 extending toward the clamping member 411, and the pair of force-applying portions 4131 are respectively arranged corresponding to the two clamping members 411, and a second mating inclined surface 4130 is arranged at the end of each force-applying portion 4131 facing the side of the other force-applying portion 4131, and the distance of the second mating inclined surface 4130 on the pair of force-applying portions 4131 close to one end of the clamping member 411 is greater than the distance away from one end of the clamping member 411, that is, the second mating inclined surfaces 4130 on the pair of force-applying portions 4131 are arranged in an eight-shaped shape, so as to provide a directional pushing force for the two clamping members 411 when mating with the two clamping members 411. It can be understood that in some embodiments, the force applying portion 4131 may also be disposed on the clamping member 411 , and accordingly, the first mating inclined surface 4112 may be disposed on the force applying portion 4131 , and the second mating inclined surface 4130 may be disposed on the pushing member 413 .

As shown in FIG. 56 , the force-applying portion 4131 and the clamping member 411 located at the top in the second direction B2 are shown. When the pusher 413 moves toward the clamping member 411 in the first direction B1, and the second matching inclined surface 4130 of the force-applying portion 4131 of the pusher 413 contacts the first matching inclined surface 4112 of the clamping member 411, the force-applying portion 4131 exerts a force F perpendicular to the first matching inclined surface 4112 on the clamping member 411. The force F can be decomposed into a force F2 along the second direction B2 and a force F1 perpendicular to F2. The force F2 can push the clamping member 411 to move along the second direction B2. The clamping member 411 can only move along the corresponding axis in the second direction B2, and the elastic restoring force of the elastic member 412 on the clamping member 411 is opposite to the direction of the force F2. Therefore, when the force F2 in the second direction B2 is greater than the elastic restoring force, the clamping member 411 moves downward in the second direction B2.

It can be understood that the clamping member 411 located at the bottom in the second direction B2 is similar, so when the two clamping members 411 are close to each other, the locking assembly 41 can be switched from the unlocked state to the locked state.

For the clamping member 411 located at the upper side in the second direction B2, when the pushing member 413 moves away from the clamping member 411 in the first direction B1, the force F decreases, and the force F2 in the second direction B2 decreases. When the force F2 in the second direction B2 is less than the elastic reset force, the clamping member 411 moves upward. The same is true for the clamping member 411 located at the lower side in the second direction B2. Therefore, when the two clamping members 411 move away from each other, the locking assembly 41 can be switched from the locked state to the unlocked state.

It can be understood that in other embodiments, for example, in an embodiment where only one clamping member 411 is movable and/or the elastic member 412 is arranged at one end of a movable clamping member 411 away from the other clamping member 411, the first mating bevel 4112 and the second mating bevel 4130 can be arranged according to the same or similar principle as that of the embodiment.

In some embodiments, the pushing member 413 may be arranged in a block shape. The pushing member 413 and the clamping member 411 may be distributed along the first direction B1 respectively. The pushing member 413 is provided with a through hole 4132 for the belt-shaped medium conveyor belt 22 to pass through. The through hole 4132 may be located between the two force-applying portions 4131 and pass through the pushing member 413 in the first direction B1. The through hole 4132 corresponds to the clamping surfaces 4111 of the two clamping members 411.

Referring to Figures 54a to 54c together, when the pushing member 413 moves toward the clamping member 411 in the first direction B1 and acts on the clamping member 411, the second mating inclined surface 4130 abuts against the first mating inclined surface 4112, and the pushing member 413 pushes the clamping member 411 to move through the second mating inclined surface 4130 to clamp the belt-like medium conveyor belt 22, and the elastic member 412 is in a compressed state, that is, the pushing member 413 contacts and cooperates with the clamping member 411, so that the two clamping members 411 are in a locked state, clamping the belt-like medium conveyor belt 22; when the pushing member 413 continues to move toward the side where the clamping member 411 is located in the first direction B1, it will drive the clamping member 411 to move together, and drive the belt-like medium conveyor belt 22 to move.

As shown in Figures 55a to 55c, when the pusher 413 moves away from the clamping member 411 in the first direction B1, the second matching slope 4130 moves away from the first matching slope 4112, the pusher 413 releases the effect on the clamping member 411, and the elastic member 412 releases the elastic reset force to push the clamping member 411 to move, and the two clamping members 411 are in an unlocked state, releasing the strip-shaped medium conveying belt 22. When the pusher 413 resumes moving toward the clamping member 411 in the first direction B1 and acts on the clamping member 411, the next transmission of the strip-shaped medium conveying belt 22 is performed. Among them, when the pusher 413 moves away from the clamping member 411 in the first direction B1, the clamping member 411 also moves toward the pusher 413 in the first direction B1, so that the pusher 413 can act on it, and the next transmission of the strip-shaped medium conveying belt 22 is realized.

As shown in FIG. 49 , in some embodiments, the locking assembly 41 further includes a first mounting seat 414, and the at least one clamping member 411 is disposed on the first mounting seat 414 so as to be movable back and forth along the second direction B2. The pushing member 413 is disposed on the first mounting seat 414 so as to be movable back and forth along the first direction B1, and can drive the first mounting seat 414 to move back and forth along the first direction B1.

Specifically, the two clamping members 411 can be arranged on the first mounting seat 414 so as to move back and forth along the second direction B2. The first mounting seat 414 can be provided with a mounting shaft 415, which is extended along the second direction B2. The two clamping members 411 are respectively sleeved on the mounting shaft 415, so as to move back and forth along the second direction B2 on the first mounting seat 414. The elastic member 412 is arranged between the two clamping members 411, and is an elastic restoring force for the two clamping members 411 to move away from each other.

In some embodiments, two mounting shafts 415 may be provided on the first mounting seat 414, and the two mounting shafts 415 are respectively located on both sides of the belt medium conveyor belt 22 in the first direction B1, and each clamping member 411 is respectively sleeved on the two mounting shafts 415 through two mounting rings 417, so that the clamping member 411 has better balance when moving up and down along the second direction B2.

The first mounting seat 414 may also be provided with two spacers 416, which are respectively arranged corresponding to the two mounting shafts 415, and the spacers 416 are provided with first mounting holes 4161 for the mounting shafts 415 to pass through, and the mounting shafts 415 are inserted into the first mounting holes 4161 to achieve the installation of the mounting shafts 415. The spacers 416 may also separate the two clamping members 411. The elastic member 412 on each mounting shaft 415 may include two columnar springs, which are respectively sleeved on the mounting shaft 415 and located between the corresponding clamping member 411 and the spacers 416, to provide elastic reset force for the corresponding clamping member, and the two clamping members 411 are respectively driven by independent springs, so as to achieve better stability.

As shown in FIG. 49 , the first mounting seat 414 may be in the shape of a rectangular frame, and may include a top wall 4141, a bottom wall 4142 opposite to the top wall 4141, and a support wall 4143 connecting the top wall 4141 and the bottom wall 4142. The two mounting shafts 415 are arranged in the first mounting seat 414 at intervals, and the two ends are respectively fixed on the top wall 4141 and the bottom wall 4142. The two spacers 416 are respectively arranged on the two support walls 4143 and extend toward each other. The top wall 4141 and the bottom wall 4142 are correspondingly provided with second mounting holes 4145 for mounting the ends of the mounting shafts 415.

The push member 413 is installed in the first mounting seat 414. The first mounting seat 414 has a first position C and a second position D spaced apart in the first direction B1. The push member 413 can move back and forth between the first position C and the second position D relative to the first mounting seat 414. When the push member 413 moves from the second position D to the first position C, the push member 413 acts on the clamping member 411 to provide a driving force for the clamping member 411. When the push member 413 moves from the first position C to the second position D, the driving force of the push member 413 acting on the clamping member 411 is removed.

As shown in Figures 47 to 49, the transmission device 40 further includes a second mounting seat 42, and the first mounting seat 414 is disposed on the second mounting seat 42 so as to be movable back and forth along the first direction B1; a damping device is disposed between the first mounting seat 414 and the second mounting seat 42, for providing a damping force to the first mounting seat 414 when the first mounting seat 414 moves relative to the second mounting seat 42. It can also be said that the transmission device 40 may further include a second mounting seat 42 in some embodiments, and the second mounting seat 42 may be fixed to the housing 101 of the aerosol generating system 100, so as to realize continuous conveyance of the belt-shaped medium conveyor belt 22 by the back and forth movement of the locking assembly 41 relative to the second mounting seat 42.

Specifically, the first mounting seat 414 of the locking assembly 41 can be arranged on the second mounting seat 42 so as to be movable back and forth along the first direction B1. Due to the wedge-shaped fit between the pushing member 413 and the at least one clamping member 411, the pushing member 413 will also generate a pushing component force F1 in the same direction as the moving direction of the pushing member 413 on the first mounting seat 414 during the process of pushing the at least one clamping member 411 to move along the second direction B2 relative to the first mounting seat 414 (as shown in FIG. 56 ). A damping device is provided between the first mounting seat 414 and the second mounting seat 42, and the damping device provides a damping force in the opposite direction to the pushing component force F1 for the first mounting seat 414, and the damping force is greater than the pushing component force.

Due to the existence of the damping force, the relative positions of the first mounting seat 414 and the second mounting seat 42 are fixed during the process of the pushing member 413 pushing the at least one clamping member 411 to move. After the at least one clamping member 411 moves into place, the pushing member 413 is fixed relative to the first mounting seat 414, and the driving force generated by the pushing member 413 is fully transmitted to the first mounting seat 414, thereby driving the first mounting seat 414 to overcome the damping force between the first mounting seat 42 and the second mounting seat 42 to move relative to the second mounting seat 42.

As can be seen from FIG. 56 , in the illustrated embodiment, when the push member 413 moves toward the clamping member 411 and contacts and cooperates with the clamping member 411, the first mounting seat 414, i.e., the clamping member 411, is subjected to a damping force in the opposite direction to the pushing force F1 in the first direction B1, and the damping force can offset the pushing force F1 in the first direction B1. Therefore, the two clamping members 411 can only move closer to each other along the second direction B2; when the push member 413 continues to move toward the clamping member 411, and when the pushing force generated by the push member 413 is fully transmitted to the first mounting seat 414, and the pushing force is greater than the damping force, the clamping member 411 drives the first mounting seat 414 to move to the side away from the push member 413. In some embodiments, the damping force between the first mounting seat 414 and the second mounting seat 42 can be set to be greater than twice the pushing force F1.

In some embodiments, the second mounting seat 42 may be a frame structure, and the second mounting seat 42 may include a top 421 and two side walls 422 connected to the top 421, and the two side walls 422 are spaced apart and arranged opposite to each other in the first direction B1. The interior of the second mounting seat 42 has a third position E and a fourth position F spaced apart in the first direction B1. The first mounting seat 414 is disposed in the second mounting seat 42, and the first mounting seat 414 can move back and forth between the third position E and the fourth position F of the second mounting seat 42 along the first direction B1 to realize the movement of the locking assembly 41 in the second mounting seat 42.

As shown in Figures 49 and 51, the transmission device 40 in some embodiments may also include a guide structure 43 for guiding the movement of the locking assembly 41. Under the guidance of the guide structure 43, the locking assembly 41 moves back and forth between the third position E and the fourth position F of the second mounting seat 42 along the first direction B1.

The guide structure 43 may be disposed between the first mounting seat 414 and the second mounting seat 42 . The guide structure 43 may include a guide groove 431 disposed on one of the first mounting seat 414 and the second mounting seat 42 and a guide rail 432 correspondingly disposed on the other. The guide groove 431 and the guide rail 432 may extend along the first direction B1 .

The outer wall surface of the top wall 4141 of the first mounting seat 414 is opposite to the inner wall surface of the top 421 of the second mounting seat 42, and the guide groove 431 and the guide rail 432 can be respectively arranged on the two opposite surfaces of the top wall 4141 of the first mounting seat 414 and the top 421 of the second mounting seat 42. In this embodiment, the guide groove 431 can be arranged on the outer wall surface of the top wall 4141 of the first mounting seat 414, and the guide groove 431 passes through both ends of the first mounting seat 414 in the first direction B1. The guide rail 432 can be correspondingly arranged on the inner wall surface of the top 421 of the second mounting seat 42, and the guide rail 432 can extend from the third position E to the fourth position F, and the side wall 422 restricts the first mounting seat 414 from moving between the third position E and the fourth position F of the second mounting seat 42. In some embodiments, the guide groove 431 can be a dovetail groove, and the guide rail 432 can be a dovetail-type guide rail 432 adapted to the dovetail groove.

In other embodiments, the second mounting seat 42 may also include a connecting wall arranged on at least one of the two opposite sides in the first direction B1, and the connecting wall is connected to the top 421 and the side wall 422. One of the guide rail 432 and the guide groove 431 may be arranged on the connecting wall of the second mounting seat 42, and the other is correspondingly arranged on the first mounting seat 414 and/or the pushing member 413 of the locking assembly.

In some embodiments, a damping device between the first mounting seat 414 and the second mounting seat 42 may be disposed on the guide structure 43, for example, the damping device may be disposed between the guide groove 431 and the guide rail 432, so as to control the damping force between the first mounting seat 414 and the second mounting seat 42. The damping device may be damping grease, which may be achieved by applying the damping grease to the guide groove 431 and/or the guide rail 432. The damping grease is a high-resistance lubricating grease, which enables the first mounting seat 414 to move more steadily, smoothly, and accurately, and can reduce noise during operation.

It can be understood that the damping grease can be set and adjusted according to the requirements of the damping force, so that the two clamping members 411 can be moved closer first and then driven to move together by the pushing member 413. In other embodiments, the damping device can be other structures such as a damping sheet and a damper that have a damping effect. In other embodiments, the damping device can be set at a position other than the guide structure 43.

In some embodiments, the transmission device 40 may further include a guide structure 44 for guiding the movement of the belt-shaped medium conveyor belt 22, and the guide structure 44 may guide the belt-shaped medium conveyor belt 22 to be transmitted in the first direction B1. Specifically, in combination with FIGS. 47 to 50, the guide structure 44 may be disposed on the second mounting seat 42, and may be disposed on two side walls 422, respectively, and each guide structure 44 may include two rollers 441 disposed at intervals, the two rollers 441 are parallel to each other, and a gap 442 is formed between the two rollers 441 for guiding the belt-shaped medium conveyor belt 22 to pass through.

The roller 441 is rotatably disposed on the side wall 422, and the belt-shaped medium conveyor belt 22 passes through the gap 442 and is driven to move by the rolling of the two rollers 441. The guide structure 44 plays a role in positioning and guiding the movement of the belt-shaped medium conveyor belt 22 in the first direction B1. The side wall 422 is provided with an opening 4221 corresponding to the guide structure 44, the roller 441 is located in the opening 4221, and the gap is located in the opening 4221.

The two gaps 442 correspond to the through-holes 4132 of the pusher 413, the space between the clamping surfaces 4111 of the two clamping members 411, and the space between the two supporting walls 4143 of the first mounting seat 414, wherein the corresponding parts can be centrally aligned, i.e., centrally aligned in the second direction B2, so that the belt-shaped medium conveyor belt 22 can be smoothly transported in the first direction B1. In other embodiments, the guide structure 44 can be implemented with other structures as long as it can guide the movement of the belt-shaped medium conveyor belt 22 in the first direction B1.

As shown in FIG. 48 and FIG. 49 , in some embodiments, the second mounting seat 42 may be provided with a buffer 45, which may be respectively arranged on two side walls 422, and the buffer 45 corresponds to the first mounting seat 414, and specifically may correspond to two pairs of adjacent support walls 4143 of the first mounting seat 414, and the inner wall surface of the side wall 422 of the second mounting seat 42 is provided with a mounting groove 3222 for the buffer 45 to be installed. It can be understood that when the first mounting seat 414 moves to the third position E or the fourth position F, the buffer 45 plays a buffering role on the first mounting seat 414, and has the effect of shock absorption and noise prevention. Among them, the buffer 45 can be arranged away from the top 421, and of course, the buffer 45 can also be arranged close to the top 421, as long as it does not affect the work of each component and the transmission of the belt-shaped medium conveyor belt 22.

As shown in Figures 48 to 50, in some embodiments, the driving assembly 46 may include a motor 461, a screw rod 462 driven by the motor 461, and a lever 463 driven by the screw rod 462. The lever 463 is connected to the pushing member 413 of the locking assembly 41 and can move back and forth along the first direction B1 under the drive of the screw rod 462 to drive the pushing member 413 to move back and forth along the first direction B1.

Specifically, the screw rod 462 can be disposed above or below the second mounting seat 42, and the axial direction of the screw rod 462 is parallel to the first direction B1. The length of the screw rod 462 can be set according to the distance between the third position E and the fourth position F in the first direction B1, so that the lever 463 has a sufficient movement stroke to drive the locking assembly 41 to move back and forth between the third position E and the fourth position F.

In some embodiments, the driving component 46 can be disposed below the second mounting seat 42 . A base 423 for mounting the driving component 46 is disposed below the second mounting seat 42 . The base 423 has a receiving space 4231 , and the driving component 46 is installed in the receiving space 4231 .

The base 423 may include a partition wall 4232 connected to the two side walls 422, and a surrounding wall 4233 extending from the partition wall 4232 away from the side wall 422, the surrounding wall 4233 has an open opening 4221 opposite to the partition wall 4232, and the base 423 may also include a bottom plate 4235 blocking the open opening 4221; the partition wall 4232, the surrounding wall 4233 and the bottom plate 4235 together define the accommodating space 4231.

The base plate 4235 and the surrounding wall 4233 may be connected via a connecting structure, which may include a first connecting tube 471 disposed on the surrounding wall 4233, a second connecting tube 472 correspondingly disposed on the base plate 4235, and a bolt 473. The inner wall of the first connecting tube 471 is provided with an internal thread matching the external thread of the bolt 473. The bolt 473 is fixedly installed in the second connecting tube 472 and is threadedly engaged with the internal thread of the first connecting tube 471.

The motor 461 and the screw rod 462 can be installed on the base plate 4235, and the lever 463 can be connected to the screw rod 462 through a screw nut matching the screw rod 462. The screw nut can move along the axial direction (i.e., the first direction B1) of the screw rod 462 following the rotation of the screw rod 462, thereby driving the locking assembly 41 to move in the first direction B1.

In some embodiments, the driving assembly 46 is connected to the pusher 413 , and the driving assembly 46 first drives the pusher 413 to act on at least one clamping member 411 to lock the belt-shaped medium conveyor belt 22 , and then drives the locking assembly 41 to move as a whole, thereby driving the belt-shaped medium conveyor belt 22 to move.

As shown in FIGS. 49 and 50 , in some embodiments, the lever 463 may include a sleeve portion 4631 sleeved on the screw nut and a rod portion 4632 connected to the pusher 413. The pusher 413 is provided with a slot 4133 with an opening facing downward for connection with the drive assembly 46. It is understandable that the pusher 413 and the drive assembly 46 are not limited to being matched through the slot 4133, and they may also be connected in other conventional ways.

The sleeve portion 4631 of the lever 463 can be located in the accommodating space 4231 of the base 423, and the rod portion 4632 can pass through the partition wall 4232 to be inserted into the slot 4133. The partition wall 4232 is provided with a moving channel 4234 for the lever 463 to move back and forth in the first direction B1. The moving channel 4234 extends along the first direction B1 and corresponds to the screw rod 462.

In some embodiments, the push member 413 is disposed in the first mounting seat 414, and the bottom surface of the push member 413 can be flush with the outer surface of the bottom wall 4142 of the first mounting seat 414. The slot 4133 extends from the bottom surface of the push member 413 to the inside of the push member 413, and the length of the lever 463 in the second direction B2 is greater than the depth of the slot 4133 in the second direction B2. Therefore, when the lever 463 is plugged into the slot 4133, the top of the push member 413 lifts up the first mounting seat 414.

In some embodiments, there is a gap between the bottom surface of the pusher 413 and the outer surface of the bottom wall 4142 of the first mounting seat 414 and the upper surface of the partition wall 4232, so that when the locking assembly 41 moves in the first direction B1, the damping effect of the damping device is located between the top 421 of the second mounting seat 42 and the top wall 4141 of the second mounting seat 42, so as to facilitate the adjustment of the damping force. A hollow groove may be provided inside the pusher 413 to reduce the weight of the pusher 413 and maintain the stability of movement.

It can be understood that the connection between the motor 461 and the lever 463 is not limited to being connected through the screw rod 462, and other transmission structures such as gear transmission, belt transmission, etc. may also be applicable.

In some embodiments, the driving assembly 46 may further include a speed regulating box 464, which is disposed on the bottom plate 4235, and the screw rod 462 and the gear are rotatably mounted in the speed regulating box 464. The motor 461 may be fixedly mounted on the bottom plate 4235, and the wiring terminal of the motor 461 is connected to the cable 465, and the cable 465 may be parallel to the second direction B2 and extend to the outside of the second mounting seat 42 for easy wiring, wherein the motor 461 may be a stepping motor, and the cable 465 may be a flexible cable.

In some embodiments, the base 423 of the driving component 46 can be located above the second mounting seat 42, the driving component 46 is installed in the base 423, and the moving channel 4234 is arranged at the top 421 of the second mounting seat 42; the guide structure 43 can be arranged between the bottom wall 4142 of the first mounting seat 414 and the partition wall 4232 of the base 423, and the driving component 46 can also be used to drive the pushing member 413 to move.

The transmission device 40 is further described below in conjunction with the working principle:

As shown in Figure 48, when the transmission device 40 is working, the belt medium conveyor belt 22 can enter the second mounting seat 42 from the outside of the second mounting seat 42 through the gap 442 between the two rollers 441 close to the pushing member 413, and then pass through the through hole 4132 of the pushing member 413, between the two clamping members 411, and the gap 442 between the two rollers 441 away from the pushing member 413, and then pass through the second mounting seat 42.

Referring to Figures 54a to 54c together, the motor 461 rotates and drives the screw rod 462 to rotate, and the lever 463 drives the pushing member 413 to move from the second position D of the first mounting seat 414 to the first position C. In the process of the pushing member 413 moving to the left, the pushing member 413 contacts and cooperates with the two clamping members 411 through its two force-applying parts 4131 respectively. Due to the damping force between the first mounting seat 414 and the second mounting seat 42, the first mounting seat 414 is stationary relative to the second mounting seat 42 at this time, and the two clamping members 411 move closer to each other in the second direction B2 and clamp the belt medium conveyor belt 22; when the pushing member 413 continues to move to the left, the pushing member 413 drives the first mounting seat 414 to move to the left together, and the clamping assembly drives the belt medium conveyor belt 22 to move to the left together, thereby realizing the transmission of the belt medium conveyor belt 22 in the first direction B1.

As shown in Figures 55a to 55c, after completing one transmission of the belt medium conveyor belt 22, the motor 461 rotates in the opposite direction and drives the screw rod 462 to rotate in the opposite direction. The lever 463 drives the pushing member 413 to move from the first position C of the first mounting seat 414 to the second position D. In the process of the pushing member 413 moving to the right, the two force-applying parts 4131 of the pushing member 413 respectively disengage from the two clamping members 411, and release the cooperation with the two clamping members 411. Under the action of the elastic member 412, the two clamping members 411 move away from each other. At this time, the locking assembly 41 is relatively separated from the belt medium conveyor belt 22; when the pushing member 413 continues to move to the right, the pushing member 413 drives the first mounting seat 414 to move to the right together.

In a specific implementation, the control method can be to drive the locking component 41 to move from the fourth position F of the second mounting seat 42 to the third position E to perform one transmission of the belt medium conveyor belt 22; then drive the locking component 41 to move from the third position E to the fourth position F, and release the belt medium conveyor belt 22 during the movement, and return to the fourth position F for the next transmission.

In other embodiments, the control method may be to control the pushing member 413 to move to the left for a period of time, drive the belt medium conveyor belt 22 to move a distance, then stop for a period of time, and then continue to move to the left, and continue to drive the belt medium conveyor belt 22 to move a distance; or, control the pushing member 413 to move to the left for a period of time, drive the belt medium conveyor belt 22 to move a distance, and then control the pushing member 413 to move to the right, release the belt medium conveyor belt 22, and then control the pushing member 413 to move to the left for the second transmission of the belt medium conveyor belt 22.

57 and 58 show a transmission device 40 in other embodiments of the present invention. As shown in the figure, the transmission device 40 can be applied to the aerosol generating system 100 to transmit the strip-shaped medium conveyor belt 22 provided with positioning holes 223. There can be a plurality of positioning holes 223, which are spaced apart along the length direction of the strip-shaped medium conveyor belt 22, and the positioning holes 223 can be evenly distributed.

The main difference between the transmission device 40 of the transmission device 40 of the above-mentioned embodiment is that the locking component 41 can be locked with the belt medium conveyor belt 22 by plugging instead of clamping, that is, when the locking component 41 is in a locked state, the locking component 41 can be plugged and fixed with the belt medium conveyor belt 22, and is relatively fixed with the belt medium conveyor belt 22, and the two become a whole.

The locking assembly 41 may include at least one locking member 411a, on which a third matching inclined surface 4112a having the same structure as the first matching inclined surface 4112 is provided. The locking member 411a may be provided with a limiting column 4111a extending along the second direction B2, and the limiting column 4111a is adapted to the positioning hole 223 on the belt-shaped medium conveying belt 22 to be transmitted, so that when the locking member 411a is matched with the positioning hole 223 through its limiting column 4111a, that is, when the limiting column 4111a is inserted into the positioning hole 223, the locking assembly 41 is relatively fixed to the belt-shaped medium conveying belt 22, thereby driving the belt-shaped medium conveying belt 22 to move.

The positioning hole 223 may be circular or in other shapes, the limiting post 4111a may be cylindrical or in other cylindrical shapes matching the positioning hole 223, and the cross-sectional dimensions of the limiting post 4111a are adapted to the dimensions of the positioning hole 223, for example, the dimensions of the two are the same, so that the limiting post 4111a can be inserted into the positioning hole 223 and become one with the belt-shaped medium conveyor belt 22, and can be easily withdrawn from the positioning hole 223 for the next transmission. The limiting post 4111a and the positioning hole 223 may be provided with a plurality of corresponding ones in the width direction to facilitate quick plug-in matching.

It is understandable that the locking assembly 41 is not limited to locking the belt-shaped medium conveyor belt 22 in the above manner, and it can also be fixed by other means such as a magnetic structure, a suction cup, etc.

It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
