[0054] A first mounting base 22 may be provided on the mounting plate 21, which can be used to mount the microwave heating assembly 30. In some embodiments, a first groove 221 may be provided on the first mounting base 22, into which the microwave heating assembly 30 can be partially inserted.

In some embodiments, the limiting seat 24 may be provided with a second groove 241, which may be generally semi-cylindrical and may be positioned opposite to the insertion port 11, communicating with the insertion port 11 to form a channel for the insertion of the aerosol generating matrix 200. Part of the aerosol generating matrix 200 is fixed in the channel, thereby keeping the aerosol generating matrix 200 stationary during the suction process. Second protrusions 242 are formed on two opposite sides of the second groove 241, and the end face of the second protrusions 242 is provided with a third connecting hole 2421. In some other embodiments, the limiting seat 24 may be omitted.

[0057] In this embodiment, the bracket 20 further includes a support plate 25 disposed at one end of the mounting plate 21. The support plate 25 is disposed perpendicularly to the mounting plate 21 and is located at the end of the mounting plate 21 away from the insertion port 11. It can be used for mounting the microwave generating unit 90. In some embodiments, the support plate 25 may also be omitted.

[0058] In this embodiment, a fixing seat 26 may be provided on the bracket 20. The fixing seat 26 may be disposed above the support plate 25 and may be disposed near the plug-in port 11. The fixing seat 26 may be used to fix the power supply 102. In some embodiments, the fixing seat 26 may also be omitted.

[0059] In other embodiments, the bracket 20 may not be limited to the structure described above. The bracket 20 may be any support structure or mounting structure that can be used to support or install components such as the microwave heating assembly 30.

[0060] In this embodiment, the microwave heating assembly 30 can be mounted on the first mounting base 22. The microwave heating assembly 30 includes an outer conductor unit 31 and an inner conductor unit 32. The outer conductor unit 31 can be a hollow structure, and the inner conductor unit 32 can be partially disposed in the outer conductor unit 31. The two can cooperate to form an energy field when microwaves are fed in, thereby heating the matrix segment 201 of the aerosol generating matrix 200 inserted into the microwave heating assembly 30. In some embodiments, the microwave heating assembly 30 can define a cavity 310, which can be formed in the outer conductor unit 31 and located between the inner conductor units 32, and can be used for microwave feeding.

[0061] In this embodiment, the outer conductor unit 31 is made of metal or other highly conductive material and is used to confine microwave capabilities therein. In some embodiments, the outer conductor unit 31 is a cylindrical structure and can be a regular shape, such as a cuboid or a cylinder. In some embodiments, the outer conductor unit 31 can be an irregular shape. Specifically, in this embodiment, the outer conductor unit 31 is a partially convex irregular shape.

[0062] In this embodiment, the outer conductor unit 31 has a first end wall 31a and a second end wall 31b; the first end wall 31a and the second end wall 31b are arranged opposite each other in the axial direction of the outer conductor unit 31, and a cavity 310 is formed between the first end wall 31a and the second end wall 31b. In some embodiments, a heating zone 3101 for inserting and heating a matrix segment 201 of the aerosol generation matrix 200 may be formed in the cavity 310, and the heating zone 3101 may be disposed close to the first end wall 31a. In some embodiments, the heating zone 3101 may be movable between a first position and a second position of the matrix segment 201, thereby realizing segmented heating of the matrix segment 201. The first position may be the position where the matrix segment 201 is connected to the cooling segment 202, and the second position may be the end of the matrix segment 201 away from the cooling segment 202. Generally, in some embodiments, the microwave heating assembly 30 can be moved along the axial direction of the substrate segment 201, thereby allowing the heating zone 3101 to be moved between a first position and a second position of the substrate segment 201.

[0063] like Figures 2 to 5 As shown, by moving the heating zone 3101 between the first and second positions of the matrix segment 201, segmented heating of the matrix segment 201 can be achieved while keeping the aerosol generating matrix 200 stationary, which conforms to user habits and improves the user experience. In some embodiments, the width of the heating zone 3101 can be kept constant.

[0064] The first position can be the starting position, and the second position can be the ending position. At the first position, the user takes a breath, and the heating zone 3101 moves a set distance to the second position and then stops, waiting for the heating zone 3101 to generate energy to heat the matrix segment 201 of the aerosol generating matrix 200, causing it to generate aerosol for the user to inhale. After the user finishes inhaling, they take another breath, and the heating zone 3101 continues to move a set distance to the second position. This process is repeated a set number of times until the heating zone 3101 is at the second position. The set distance can be 1 mm, and the set number of breaths can be 12. Of course, it is understood that in other embodiments, the set distance and the set number of breaths can be set according to actual needs. After the user finishes inhaling, the heating zone 3101 can also move from the second position of the matrix segment 201 back to the first position. Specifically, the microwave heating assembly 30 can move as a whole towards the insertion / removal port 11, thereby prompting the user to remove the aerosol generating matrix 200.

[0065] In this embodiment, the outer conductor unit 31 may include an outer conductor body 311 and a top cover structure 312. The outer conductor body 311 may be a cylindrical structure. An opening 3110 may be provided on the outer conductor body 311, and the opening 3110 may be located at one end of the outer conductor body 311. The top cover structure 312 may be installed at the opening 3110, and it may cover the opening 3110. The first end wall 31a may be formed on the top cover structure 312.

[0066] In this embodiment, the second end wall 31b may be formed at one end of the outer conductor body 311 opposite to the opening 3110. A through hole 3111 may be provided on the second end wall 31b, and the through hole 3111 may be provided at the central axis of the second end wall 31b. The through hole 3111 can be used for the inner conductor unit 32 to pass through.

[0067] In this embodiment, the upper cover structure 312 can be sleeved on the outer conductor body 311 and can be fixed to the outer conductor body 311 by screwing. In some other embodiments, the upper cover structure 312 can also be fixed to the outer conductor body 311 by interference fit or by providing a snap-fit ​​structure. In some embodiments, the upper cover structure 312 may include a cover portion 3121 and a guide portion 3122. The cover portion 3121 can cover the outer conductor body 311. The guide portion 3122 can protrude from the cover portion 3121. Specifically, the guide portion 3122 can protrude from the side of the first end wall 31a opposite to the cavity 310. In some embodiments, the guide portion 3122 can be columnar. The cover structure 312 may be provided with a through hole 3123, which can communicate with the cavity 310. The aerosol generating matrix 200 can pass through the through hole 3123 and be inserted into the cavity 310.

[0068] In this embodiment, the inner conductor unit 32 at least partially penetrates the cavity 310 from the second end wall 31b and can extend toward the first end wall 31a. The heating zone 3101 is formed by the gap between the end of the inner conductor unit 32 facing the first end wall 31a and the first end wall 31a. In some embodiments, the outer conductor unit 31 and the inner conductor unit 32 are fixedly connected and can be moved synchronously, so that the heating zone 3101 can be moved while maintaining a constant width. In other embodiments, only a portion of the structure in the microwave heating assembly 30 can be moved axially along the matrix segment 201, for example, the inner conductor unit 32 and the upper cover structure 312 can be moved simultaneously, thereby allowing the heating zone 3101 to move as well.

[0069] In some embodiments, the inner conductor unit 32 may include a radiating portion 321 and a plug-in portion 322. The radiating portion 321 may be cylindrical with a hollow inner side, and a guide channel 3210 may be defined inside the radiating portion 321 to facilitate the movement and guidance of the microwave heating assembly 30. The radiating portion 321 may extend from the second end wall 31b to the first end wall 31a, with one end contacting the second end wall 31b and the other end spaced apart from the first end wall 31a to form the heating zone 3101. The end of the radiating portion 321 facing the first end wall 31a may have a channel opening 3211 communicating with the guide channel 3210. The channel opening 3211 may communicate with the heating zone 3101, allowing the aerosol generating matrix 200 to pass through. The plug portion 322 may be disposed at the end of the radiating portion 321 away from the first end wall 31a. It may be columnar and may be inserted into the through hole 3111, and may be interference-fitted with the through hole 3111, thereby realizing the connection and fixation between the outer conductor unit 31 and the inner conductor unit 32. In some embodiments, the plug portion 322 may be integrally formed with the radiating portion 321.

[0070] In some embodiments, the microwave heating assembly 30 further includes a microwave feed unit 33, which can be mounted on the outer conductor body 311 and can be moved synchronously with the outer conductor unit 31. In some embodiments, the microwave feed unit 33 can be an SMA coaxial connector. The microwave feed unit 33 can be connected to the microwave generating unit 90 and can feed the microwaves generated by the microwave generating unit 90 into the cavity 310. In some embodiments, the microwave feed unit 33 and the microwave generating unit 90 can be connected by a flexible hose 101. When the heating zone 3101 is in a first position of the matrix section 201, the flexible hose 101 is in a stretched state. When the heating zone 3101 is in a second position of the matrix section 201, the flexible hose 101 can be in a bent state.

[0071] like Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, in some embodiments, the aerosol generating device further includes a drive assembly 50 connected to the microwave heating assembly 30, which can drive the microwave heating assembly 30 to move axially along the matrix segment 201. In some embodiments, the drive assembly 50 can be mounted on the mounting plate 21 and located on the side of the microwave heating assembly 30 away from the plug-in port 11.

[0072] In this embodiment, the driving assembly 50 may include a driving member 51 and a push rod 52. One end of the push rod 52 may be connected to the driving member 51, and the other end may extend toward and connect to the microwave heating assembly 30. In other embodiments, the driving assembly 50 is not limited to including the driving member 51 and the push rod 52.

[0073] In some embodiments, the drive element 51 can be an electric drive structure, such as a push rod stepper motor; in some embodiments, the drive element 51 can also be a pneumatic structure, such as a telescopic cylinder; in some embodiments, the drive element 51 can also be a hydraulic structure, such as a hydraulic cylinder. Of course, it is understood that in other embodiments, the drive element 51 can also be a manually driven structure.

[0074] The push rod 52 can be connected and fixed to the outer conductor unit 31. Specifically, it can be connected to the bottom of the outer conductor body 311 and can be connected and fixed to the outer conductor body 311 through a fixing assembly 34. The fixing assembly 34 may include a connecting fixing seat that is snapped onto the outer conductor body 311. One end of the push rod 52 is inserted into the connecting fixing seat and connected and fixed to the connecting fixing seat. The connecting fixing seat can be connected and fixed to the outer conductor body 311 through a screw assembly. In some other embodiments, the fixing assembly 34 can be omitted. The bottom of the second end wall 31b of the outer conductor body 311 may have an insertion hole for the push rod 52 to mate with.

[0075] When the drive unit 51 is activated, it can drive the push rod 52 to move away from the plug-in port 11, which in turn can drive the microwave heating assembly 30 to move away from the plug-in port 11, thereby allowing the heating zone 3101 to move from the first position to the second position.

[0076] In this embodiment, the aerosol generating device further includes a guide structure 60, which can cooperate with the microwave heating component 30. The guide structure 60 can guide the movement of the microwave heating component 30 and limit the movement of the microwave heating component 30 so that the microwave heating component 30 can only move along the axial direction.

[0077] In this embodiment, the guiding structure may include a guide rod 61 extending axially along the matrix segment 201.

In some embodiments, the guide rod 61 may be made of a self-lubricating material, such as polytetrafluoroethylene (PTFE). Of course, it is understood that in other embodiments, the guide rod 61 may also be a conventional plastic or metal rod. The surface of the guide rod 61 may also be coated with a lubricant.

[0078] In this embodiment, there may be two guide rods 61, that is, the guide rod 61 may include a first guide rod 61a and a second guide rod 61b. In some other embodiments, there may be only one guide rod 61, and in other embodiments, there may be multiple guide rods 61, such as three or four.

[0079] In this embodiment, one end of the first guide rod 61a is inserted into the fixing hole 231. The first guide rod 61a can be fixed with the fixing hole 231 by interference fit. In some embodiments, the first guide rod 61a and the second mounting base 23 can also be connected and fixed by a connecting assembly. The connecting assembly can be a screw assembly, and the screw can be inserted through the second connecting hole 232 to connect and fix the first guide rod 61a and the second mounting base 23. The first guide rod 61a can be inserted from the insertion part 322 of the inner conductor unit 32 into the radiating part 321, and it can contact the end face of the matrix segment 201 of the aerosol generating matrix 200. In some embodiments, a support platform 611 is provided on the end face of the first guide rod 61a facing the matrix segment 201. The support platform 611 can support the aerosol generating matrix 200 and prevent the aerosol generating matrix 200 from moving away from the insertion port 11.

[0080] A first sliding sleeve 35 may be provided between the first guide rod 61a and the insertion part 322. The first sliding sleeve 35 may be interference-fitted with the insertion part 322 and may be sleeved on the outer periphery of the first guide rod 61a.

In some embodiments, the second sliding sleeve 36 can be made of a self-lubricating material, such as polytetrafluoroethylene. Of course, in some other embodiments, the second sliding sleeve 36 can also be a conventional plastic sleeve or silicone sleeve, and the inner surface of the second sliding sleeve 36 can also be coated with a lubricant in some embodiments.

[0082] In this embodiment, the guide structure further includes a fixedly disposed guide sleeve 62, which can be fixedly installed on the first mounting base 22. Specifically, the guide sleeve 62 can be connected and fixed to the first mounting base 22 by a first connecting and fixing component 40. In some embodiments, the guide sleeve 62 is a hollow structure with both ends open, and is coaxially disposed with the microwave heating component 30. In some embodiments, the microwave heating component moves through the guide sleeve 62. In some embodiments, the guide sleeve 62 can be omitted.

[0083] In this embodiment, the guide sleeve 62 can be made of a material with a certain self-lubricating effect, such as polytetrafluoroethylene. Of course, it is understood that in some other embodiments, the guide sleeve 62 can also be made of ordinary plastic or ceramic materials, and in some embodiments, a lubricant can be provided on the inner wall of the guide sleeve 62.

[0084] In this embodiment, the guide sleeve 62 may include a cylindrical body 621 and two limiting flanges 622. The cylindrical body 621 is a hollow structure with both ends open. In some embodiments, the cylindrical body 621 may be generally circular. The two limiting flanges 622 may be disposed at both ends of the cylindrical body 621 and may protrude radially along the cylindrical body 621. In some embodiments, the inner diameter of the cylindrical body 621 may be greater than or equal to the outer diameter of the outer conductor body 311 and less than the maximum outer diameter of the upper cover structure 312. That is, when the upper cover structure 312 of the outer conductor unit 31 is placed on the limiting flange 622 facing the insertion port 11, the heating zone 3101 moves to the second position.

[0085] In this embodiment, the first connecting and fixing assembly 40 may include a first pressing plate 41 and a first connecting member 42. The first pressing plate 41 may be generally U-shaped, and it can be pressed against the outer wall of the cylindrical body 621 of the guide sleeve 62, and is limited by two limiting flanges 622. The first connecting member 42 can connect and fix the first pressing plate 41 to the first boss 222 of the first mounting base 22. In some embodiments, the first connecting member 42 may be a screw, and a first through hole may be provided on the first pressing plate 41 corresponding to the first connecting hole 2221, through which the screw can pass and enter the first connecting hole 2221. The guide sleeve 62 can be connected and fixed by the first connecting and fixing assembly 40, thereby ensuring that the guide sleeve 62 remains stationary during the movement of the microwave heating assembly 30, so that the microwave heating assembly 30 is coaxial with the first guide rod 61a and "does not jam".

[0086] like Figure 3 , Figure 5 and Figure 9 As shown, in this embodiment, the aerosol generating device further includes a fixing structure 70, which can be disposed in the housing 10 and can be used to fix the aerosol generating matrix 200, thereby keeping the aerosol generating matrix 200 stationary. In some embodiments, the housing 10 may be provided with a channel for inserting the aerosol generating matrix 200, and the fixing structure 70 is at least partially disposed in the channel. Specifically, the insertion port 11, the second groove 241, and the through hole 3123 are sequentially connected to form a channel for inserting the aerosol generating matrix 200, and the fixing structure 70 may be partially disposed in the second groove 241. In some embodiments, the fixing structure 70 can be fixed to the second groove 241 by providing a second connecting fixing component 80.

[0087] In some embodiments, the fixing structure 70 may include a clamping mechanism that can clamp and fix the aerosol generating matrix 200 by generating a clamping force. In some embodiments, the clamping mechanism may be an integrally molded structure, which may be an elastic sleeve that can be in close contact with the outer structure of the aerosol generating matrix 200. The sidewalls on two opposite sides of the clamping mechanism can generate a clamping force to hold the aerosol generating matrix 200. In some embodiments, the fixing structure 70 may be made of a material with good elasticity, such as silicone, especially food-grade silicone (hardness of 45 degrees). The fixing structure 70 can be in close contact with the aerosol generating matrix 200 by interference fit.

[0088] In this embodiment, the fixing structure 70 may include a main body 71, a first limiting part 72, and a second limiting part 73. The main body 71 may be cylindrical and hollow with both ends open. At least two protrusions 711 may be provided on the inner sidewall of the main body 71. These at least two protrusions 711 are spaced apart circumferentially on the main body 71. When the aerosol generating matrix 200 passes through the fixing structure 70, these at least two protrusions 711 abut against the outer casing of the aerosol generating matrix 200, thereby clamping the aerosol generating matrix 200. In some embodiments, the at least two protrusions 711 may be three, four, or other types. The first limiting part 72 and the second limiting part 73 may be provided at both ends of the main body 71. The first limiting part 72 and the second limiting part 73 may be approximately annular, and their outer diameter may be larger than the outer diameter of the main body 71. In some embodiments, the main body 71, the first limiting part 72, and the second limiting part 73 are integrally formed. Specifically, the main body 71, the first limiting part 72, and the second limiting part 73 can be integrally formed by injection molding.

[0089] In this embodiment, the second connecting and fixing assembly 80 may include a second pressing plate 81 and a second connecting member 82. The second pressing plate 81 may be generally U-shaped, and it can be pressed against the outer wall of the main body 71 of the guide sleeve 62, and is limited by two first limiting parts 72 and a second limiting part 73. The second connecting member 82 can connect and fix the second pressing plate 81 to the second boss 242 of the limiting seat 24. In some embodiments, the second connecting member 82 may be a screw, and a second through hole may be provided on the second pressing plate 81 corresponding to the third connecting hole 2421. The screw can pass through the second through hole and into the third connecting hole 2421. The fixing structure 70 can be connected and fixed by the second connecting and fixing assembly 80, thereby ensuring that the fixing structure 70 remains stationary during the movement of the microwave heating assembly 30, so that the aerosol generating matrix 200 remains stationary.

[0090] In this embodiment, a gap may be provided between the fixing structure 70 and the limiting seat 24. The width of the gap may be 0.2mm to 0.5mm. When the aerosol generating matrix 200 passes through the fixing structure 70, the aerosol generating matrix 200 and the fixing structure 70 are in an elastic state with an interference fit (the interference amount is 0.05mm to 0.2mm, and the frictional force ensures that the aerosol generating matrix 200 can be smoothly inserted and easily pulled out after the suction is completed). The aerosol generating matrix 200 and the inner conductor unit 32 are in a clearance fit (the gap is 0.05mm to 0.2mm), ensuring that the aerosol generating matrix 200 remains stationary during the movement of the microwave heating component 30.

[0091] In this embodiment, the aerosol generating device further includes a power supply 102, which can be disposed in the mounting base 26 and can be connected to the microwave generating unit 90 to supply power to the microwave generating unit 90. In this embodiment, the power supply 102 can be a battery.

[0092] Figures 10 to 11 A second embodiment of the aerosol generating device of this utility model is shown. The difference from the first embodiment is that a base 610 can be provided at one end of the first guide rod 61a. The first guide rod 61a and the base 610 can be an integral structure, thereby avoiding increased deformation during installation, improving overall rigidity, and ensuring smooth and uninterrupted reciprocating motion of the microwave heating component 30. In some embodiments, the two can be integrally formed by injection molding or casting. In some embodiments, they can also be fixed as an integral structure by snap-fit ​​or welding. The base 610 can be connected and fixed to the second mounting base 23 and / or mounting plate 21 by providing a connecting component. A connecting through hole 6101 can be provided at the end of the base 610 facing the mounting plate 21. The connecting through hole 6101 can be used for the connecting component to pass through and be inserted into the mounting plate 21. In some embodiments, the connecting component can be a screw.

[0093] Figures 12 to 14 A third embodiment of the aerosol generating device of this utility model is shown, which differs from the first embodiment in that the guiding structure 60 may further include a guide rack 64 and a gear 65. The guide rack 64 may extend axially along the substrate segment 201 and be disposed on one side of the microwave heating assembly 30, and be connected to the microwave heating assembly 30. Specifically, in some embodiments, the guide rack 64 may be disposed on the outer side wall of the outer conductor body 311 and disposed axially along the outer conductor body 311. In some embodiments, the guide rack 64 may be integrally formed with the outer conductor body 311. The gear 65 may be disposed on one side of the guide rack 64 and mesh with the guide rack 64. The gear 65 may be mounted on the mounting plate 21 of the bracket 20. When the microwave heating assembly 30 moves axially along the substrate segment 201 under the drive of the driving assembly 50, the guide rack 64 may cooperate with the gear 65, thereby guiding the movement of the microwave heating assembly 30.

[0094] Figures 15 to 19A fourth embodiment of the aerosol generating device of this invention is shown, which differs from the first embodiment in that the push rod 52 and the first guide rod 61a of the drive assembly 50 can be omitted. The drive member 51 can be a reversible motor, which can be connected to the main control board and then to the power supply 102 via the main control board. The motor can be connected to a reducer. The motor leads can be directly soldered to the main control board and thus connected to the main control board. The drive assembly 50 may also include a lead screw 53 and a slider 54. One end of the lead screw 53 can be connected to the drive member 51, and the other end can extend toward the microwave heating assembly 30. Specifically, the lead screw 53 can be connected to the motor via the reducer. In some embodiments, the lead screw 53 can be located at the central axis of the microwave heating assembly 30 and can be inserted into the inner conductor unit 32. The slider 54 can be slidably sleeved on the lead screw 53 and can be connected to the microwave heating assembly 30. Specifically, in some embodiments, the slider 54 can be fitted onto the insertion portion 322 of the inner conductor unit 32 that protrudes from the second end wall 31b, and can be screwed to the lead screw 53. A notch can be formed on the side wall of the insertion portion 322, and the internal thread of the slider 54 can partially protrude from the notch and be screwed to the lead screw 53. Driven by the lead screw 53, the overall rigidity can be improved, and the movement of the microwave heating assembly 30 can be made smoother, solving the problems of "excessive friction" and "excessive offset" during the pushing process.

[0095] When the motor rotates forward, it can drive the lead screw 53 to rotate forward. Then, through the T-shaped thread transmission between the slider 54 and the lead screw 53, the slider 54 can drive the microwave heating component 30 to move away from the insertion port 11 along the axial direction of the substrate section 201, so that the heating zone 3101 moves from the first position to the second position.

[0096] When the motor reverses, it can drive the lead screw 53 to reverse, and then through the T-shaped thread transmission between the slider 54 and the lead screw 53, the slider 54 can drive the microwave heating component 30 to move along the axial direction of the substrate section 201 towards the insertion port 11, so that the heating zone 3101 moves from the second position to the first position.

[0097] Figure 20 The sixth embodiment of the aerosol generating device of this utility model is shown. The difference from the first embodiment is that the fixing structure 70 can also be a split structure, which may include a first clamping part 70a and a second clamping part 70b. The first clamping part 70a and the second clamping part 70b are arranged opposite to each other, and each of the first clamping part 70a and the second clamping part 70b includes a main body part 71, a first limiting part 72, and a second limiting part 73. A groove 74 with a generally V-shaped cross-section is formed on the inner side of both the first clamping part 70a and the second clamping part 70b.

[0098] Figure 21The seventh embodiment of the aerosol generating device of the present invention is shown. The difference between the seventh and sixth embodiments is that the cross-section of the groove 74 is not limited to V-shape, but can also be U-shape.
