[0019] In the following description, for purposes of explanation and not limitation, specific details are presented, such as specific system architectures, techniques, etc., to provide a thorough understanding of embodiments of the present invention. However, those skilled in the art will appreciate that the present invention may be practiced in other embodiments that do not include these specific details. In other circumstances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present invention with unnecessary detail.

[0020] According to one embodiment of the aerosol generating device 100 of the present invention, the aerosol generating device 100 may be configured to generate an aerosol by heating and atomizing the aerosol-generating product 200 with microwaves for a user to inhale or snort.

[0021] In some embodiments, referring to FIG. 1 , the aerosol generating device 100 may include a microwave heating assembly 1, a microwave generating unit (not shown), a control assembly 2, and a power supply assembly (not shown), wherein the power supply assembly is used to supply electrical energy to the microwave heating assembly 1, the microwave generating unit, and the control assembly 2, and the control assembly 2 is used to control the microwave heating assembly 1 and the microwave generating unit to operate, and the microwave generating unit may generate a microwave signal and supply microwaves to the microwave heating assembly 1 by connecting to the microwave heating assembly 1, and the microwave heating assembly 1 uses microwaves to heat the aerosol-generating product 200.

[0022] In some other embodiments, referring to Figures 2 and 3 together, the aerosol generating device 100 may include a microwave heating assembly 1, a microwave generating unit, a control assembly 2, a drive assembly 5 and a power supply assembly, wherein the power supply assembly is used to supply electrical energy to the microwave heating assembly 1, the microwave generating unit, the control assembly 2 and the drive assembly 5, wherein the control assembly 2 is used to control the microwave heating assembly 1, the microwave generating unit and the drive assembly 5 to operate, wherein the microwave generating unit may generate a microwave signal and supply microwaves to the microwave heating assembly 1, wherein the microwave heating assembly 1 uses microwaves to locally heat the aerosol generating product 200 in the circumferential direction, and wherein the drive assembly 5 is used to drive the aerosol generating product 200 to rotate relative to the microwave heating assembly 1, thereby achieving divided heating in the circumferential direction and overcoming the problems of uneven heating and slow heating rate of the aerosol generating product 200.

[0023] For example, the control assembly 2 includes an airflow sensor switch 21, which detects a change in airflow with each inhalation and controls the drive assembly 5 to drive the aerosol-generating product 200 to rotate relative to the microwave heating assembly 1, thereby changing the heated area around the circumference of the aerosol-generating product 200.

[0024] It will be appreciated that the drive assembly 5 is not a required component of the present invention and in some embodiments the relative rotation between the aerosol-generating product 200 and the microwave heating assembly 1 may also be achieved by manual control.

[0025] As shown in Figures 1 and 2, the aerosol generating device 100 may optionally further comprise a casing 3 and a mounting bracket 4 attached to the casing 3, with the microwave heating assembly 1, microwave generating unit and power supply assembly attached to the mounting bracket 4.

[0026] In some embodiments, the microwave heating assembly 1 has an approximately cylindrical appearance, but it will be appreciated that the microwave heating assembly 1 is not limited to a cylindrical shape and may have other shapes such as a rectangular cylinder or an elliptical cylinder.

[0027] 3 and 4, the microwave heating assembly 1 may include an outer conductor unit 11, an inner conductor unit 12, and a microwave supply unit 13. The outer conductor unit 11 has a closed end 111 and an open end 112 opposite the closed end 111, and may define a semi-closed cavity 113. A storage chamber 141 for storing the aerosol-generating product 200 is formed in the cavity 113, and the storage chamber 141 includes a central axis 142. The aerosol-generating product 200 (see FIG. 8) may have a cylindrical shape. The inner conductor unit 12 includes an inner conductor body 121 and a microwave radiating element 122 coupled to the inner conductor body 121, the inner conductor body 121 is connected to the closed end 111 of the outer conductor unit 11 and is in ohmic contact with the end wall of the closed end 111 to form a short-circuited end of the microwave heating assembly 1, and the microwave radiating element 122 is located in the cavity 113 but does not contact the outer conductor unit 11 to form an open-circuited end of the microwave heating assembly 1. The microwave supply unit 13 is removably attached to the outer conductor unit 11 and is used to supply microwaves generated by the microwave generating unit to the cavity 113, thereby forming a microwave field in the cavity 113 that can act on the aerosol-generating product 200.

[0028] In some embodiments, the microwave heating assembly 1 may further comprise a receiving seat 14, which may be fixedly or removably attached to the open end 112 of the outer conductor unit 11, and a receiving chamber 141 may be formed within the receiving seat 14, which is located in the main area where the microwave field is formed.

[0029] Of course, the accommodating seat 14 is not an essential component of the present invention, and the aerosol-generating product 200 may be inserted directly into the cavity 113 from the open end 112 of the outer conductor unit 11, and the accommodating seat 14 can serve to protect the cavity 113 and the inner conductor body 121 from being contaminated by mist or from being contaminated as little as possible.

[0030] As shown in Figure 3, the microwave radiating element 122 is installed away from the central axis 142 of the containing chamber 141 and is located on the outer periphery of the containing chamber 141. The microwave radiating element 122 can rotate around the central axis 142 of the containing chamber 141, or the aerosol-generating product 200 can rotate around the central axis 142 within the containing chamber 141. This allows the heated aerosol-generating product 200 to be heated in divided stages in the circumferential direction. This makes the aerosol-generating product 200 more uniformly heated, improving the heating speed, eliminating the need for waiting, and improving the atomization speed. The fast atomization speed significantly shortens the preheating time, and heating can be stopped during the suction interval, so that heating also stops when suction is stopped.

[0031] The microwave radiating element 122 may be fixed relative to the outer conductor unit 11, and the aerosol-generating product 200 may be rotatable. Specifically, the microwave radiating element 122 is fixedly installed relative to the outer conductor unit 11, and optionally, the microwave heating assembly 1 further comprises a fixing member for fixing the aerosol-generating product 200, the fixing member being rotatably installed relative to the outer conductor unit 11 around the central axis 142 of the accommodating chamber 141, so that the aerosol-generating product 200 fixed therein can rotate in the accommodating chamber 141. As will be understood, the aerosol-generating product 200 rotates relative to the accommodating chamber 141, and the inner conductor body 121, the microwave radiating element 122, and the accommodating seat 14 may each be fixedly arranged in the cavity 113, and when the aerosol-generating product 200 is inserted into the accommodating seat 14, the aerosol-generating product 200 is fixed axially relative to the accommodating seat 14, and the drive assembly 5 directly acts on the aerosol-generating product 200 to drive it to rotate about its axis.

[0032] Alternatively, the microwave radiating element 122 may be rotatable relative to the outer conductor unit 11, and the aerosol-generating product 200 may be fixed. Specifically, the microwave radiating element 122 is rotatably mounted around the central axis 142 of the accommodating chamber 141 relative to the outer conductor unit 11, and optionally, the microwave heating assembly 1 further comprises a fixing member for fixing the aerosol-generating product 200, and the fixing member is fixedly mounted relative to the outer conductor unit 11. As can be understood, the internal conductor body 121 and the microwave radiating element 122 are fixed relative to each other, and the internal conductor body 121 and the microwave radiating element 122 may be fixed axially relative to the cavity 113, and the internal conductor body 121 and the microwave radiating element 122 can rotate around the central axis of the cavity 113 by driving the driving assembly 5, the accommodating seat 14 is fixedly attached to the external conductor unit 11, the microwave radiating element 122 is positioned circumferentially around the accommodating chamber 141, and when the aerosol-generating product 200 is inserted into the accommodating seat 14, the microwave radiating element 122 and the internal conductor body 121 can rotate together around the circumferential direction of the aerosol-generating product 200.

[0033] Furthermore, the microwave radiating element 122 may be rotatable relative to the outer conductor unit 11, and the aerosol-generating product 200 may also be rotatable. Specifically, the microwave radiating element 122 is rotatably mounted around the central axis 142 of the accommodating chamber 141 relative to the outer conductor unit 11, and the microwave heating assembly 1 further includes a fixing member for fixing the aerosol-generating product 200, and the fixing member may be rotatably mounted around the central axis 142 of the accommodating chamber 141 relative to the outer conductor unit 11. As will be understood, the inner conductor body 121 is fixed to the closed end 111 of the outer conductor unit 11, and the microwave radiating element 122 may be fixed axially relative to the inner conductor body 121, but the microwave radiating element 122 can rotate circumferentially relative to the inner conductor body 121 by driving the drive assembly 5, the receiving seat 14 is fixedly attached to the outer conductor unit 11, the microwave radiating element 122 is located circumferentially around the receiving chamber 141, and when the aerosol-generating product 200 is inserted into the receiving seat 14, the microwave radiating element 122 rotates around the circumferential direction of the aerosol-generating product 200. This can be done.

[0034] Next, the direction in which the aerosol-generating product 200 rotates relative to the microwave heating assembly 1 may be determined according to actual needs, and may rotate in a single direction, for example, clockwise or counterclockwise, or may switch the rotation direction, for example, from clockwise rotation to counterclockwise rotation, or from counterclockwise rotation to clockwise rotation.

[0035] In some embodiments, as shown in FIGS. 4 and 5, the outer conductor unit 11 may include a conductor side wall 114, a conductor end wall 115, and a conductor convex wall 116.

[0036] The conductor side wall 114 may be cylindrical, the upper end of the conductor side wall 114 having an open design to form the open end 112 of the outer conductor unit 11, the lower end of the conductor side wall 114 also having an open design, and the conductor end wall 115 is integrally sealed to the lower end of the conductor side wall 114 to form the closed end 111 of the outer conductor unit 11.

[0037] The conductive protruding wall 116 is integrally connected to the outer periphery of the conductive side wall 114, and the bottom surface of the conductive protruding wall 116 (the surface away from the open end 112 of the outer conductor unit 11) may be flush with the outer end surface of the conductive end wall 115.

[0038] A supply hole 117 is formed in the conductor side wall 114 and the conductor protruding wall 116, and the supply hole 117 is formed straight through the supply hole 117 of the conductor side wall 114 and the conductor protruding wall 116 along a direction perpendicular to the central axis of the conductor side wall 114, and is used for inserting the microwave supply unit 13 into the cavity 113. Of course, the supply hole 117 may also be formed in the conductor end wall 115, and the microwave supply unit 13 is inserted into the cavity 113 from below the microwave heating assembly 1.

[0039] A protruding connection portion 1151 is formed on the inner end surface (the end surface facing the opening end 112 of the external conductor unit 11) on the conductor end wall 115, and the connection portion 1151 is used to engage with the microwave supply unit 13 and supply microwaves generated by the microwave supply unit 13 into the cavity 113.

[0040] 4, the conductor side wall 114 has a protrusion protruding outward, and a first vent hole 1141 penetrating the protrusion and the conductor side wall 114, which connects the outside of the conductor side wall 114 with the cavity 113. Optionally, the first vent hole 1141 and the drive assembly 5 are located on opposite sides of the conductor side wall 114 in the circumferential direction.

[0041] 5 , the outer conductor unit 11 may further include a first fixing plate 118 and a second fixing plate 119 integrally coupled to the outer periphery of the conductor side wall 114. The first fixing plate 118 and the second fixing plate 119 are used to fit with the mounting bracket 4 to fix the entire outer conductor unit 11 to the mounting bracket 4. Optionally, the first fixing plate 118 and the second fixing plate 119 are located on opposite sides of the conductor side wall 114, the first fixing plate 118 is integrally connected to the upper part of the conductor convex wall 116, the second fixing plate 119 is adjacent to the conductor end wall 115, and the bottom surface of the second fixing plate 119 (the surface away from the open end 112 of the outer conductor unit 11) is flush with the outer end surface of the conductor end wall 115.

[0042] 3, the central axis 142 of the chamber 141 may not coincide with the central axis of the inner conductor body 121, i.e., may be offset away from the central axis of the inner conductor body 121. Optionally, the central axis 142 of the chamber 141 is parallel to the central axis of the inner conductor body 121. Of course, the chamber 141 may be coaxial with the inner conductor body 121, and the purpose of offsetting the seat 14 is to achieve better circumferential heating of the aerosol-generating product 200. There may be a gap between the bottom of the seat 14 and the top of the inner conductor body 121, so that they are not in direct contact with each other.

[0043] Referring to Figures 4, 6 and 7 together, the receiving seat 14 may include a fixing portion 144 attached to the open end 112 of the outer conductor unit 11 and a receiving portion 143 at least partially installed in the cavity 113.

[0044] The storage section 143 may be cylindrical, but of course the shape of the storage section 143 is not limited to cylindrical and may be other shapes such as a rectangular tube. The storage section 143 and the cavity 113 are spaced apart in the circumferential direction, the outer diameter of the storage section 143 is smaller than the inner diameter of the cavity 113, and the inner diameter of the storage section 143 matches the outer diameter of the aerosol-generating product 200. The storage section 143 may include a storage bottom wall 1431 for supporting the aerosol-generating product 200, and a cylindrical storage side wall 1432 arranged around the periphery of the storage bottom wall 1431. The storage bottom wall 1431 and the storage side wall 1432 together form the storage chamber 141, which has a cylindrical shape. A second ventilation hole 1434 for communicating with the first ventilation hole 1141 is further formed in the receiving side wall 1432 , and the second ventilation hole 1434 can be disposed opposite the first ventilation hole 1141 .

[0045] The fixing portion 144 may be annular, integrally connected to the outer periphery of the accommodating side wall 1432 of the accommodating portion 143, and may be adjacent to the upper end of the accommodating side wall 1432. During assembly, the bottom end face of the fixing portion 144 (the end face facing the sealed end 111 of the outer conductor unit 11) abuts against the open end 112 of the outer conductor unit 11, thereby attaching the accommodating seat 14 to the outer conductor unit 11 and restricting the accommodating seat 14 from moving downward.

[0046] The receiving seat 14 further includes a slot 1435 formed in the receiving portion 143, which penetrates the receiving bottom wall 1431 and extends on the receiving side wall 1432 along a direction parallel to the central axis of the receiving chamber 141, penetrates the receiving bottom wall 1431, performs receiving molding, and is used to fit the microwave radiating element 122.

[0047] 4 and 7, the receiving seat 14 further includes an intake passage 1436 formed in the receiving portion 143, which not only allows external air to be introduced into the bottom of the aerosol-generating product 200 but also triggers the airflow sensor switch 21. The intake passage 1436 may include a first air duct formed in the receiving bottom wall 1431 and a second air duct formed in the receiving side wall 1432, and a second air vent 1434 may be provided in the receiving side wall 1432 at a position corresponding to the second air duct, and the second air duct may be in communication with the airflow sensor switch 21 through the second air vent 1434 to allow air to be introduced therethrough. Optionally, the second air duct and the slot 1435 may be located on opposite sides in the circumferential direction of the receiving seat 14, respectively.

[0048] As can be understood, as shown in FIG. 8, when the aerosol-generating product 200 is inserted into the receiving seat 14, the intake passage 1436 and the interior of the aerosol-generating product 200 together form an air flow passage 6, and the outside air can flow from the intake passage 1436 to the bottom of the aerosol product, then flow vertically upward from the bottom of the aerosol product into its interior, and finally reach the top of the aerosol product.

[0049] In some embodiments, as shown in FIG. 4, the inner conductor body 121 includes a conductor post 1211 and a conductor disk 1212 integrally coupled to the conductor post 1211 .

[0050] The conductive rod 1211 may have a cylindrical shape and be coaxially disposed in the cavity 113, with the outer diameter of the conductive rod 1211 being smaller than the inner diameter of the cavity 113. Naturally, the conductive rod 1211 is not limited to a cylindrical shape and may have other shapes, such as a rectangular pillar. The upper end of the conductive rod 1211 (the end close to the open end 112 of the outer conductor unit 11) is a free end that extends to the open end 112 of the outer conductor unit 11, and the lower end of the conductive rod 1211 (the end remote from the open end 112 of the outer conductor unit 11) is a fixed end that may be connected to the conductive end wall 115 of the outer conductor unit 11.

[0051] Optionally, the conductor post 1211 may include a mounting portion for attachment to the conductor end wall 115, which is screwed to the conductor end wall 115 to form a secure ohmic contact. Of course, the conductor post 1211 may also be integrally bonded directly to the conductor end wall 115.

[0052] The conductive disk 1212 is coaxially coupled to the upper end of the conductive post 1211, and the outer diameter of the conductive disk 1212 is larger than that of the conductive post 1211 and smaller than the diameter of the cavity 113. The radial distance over which the conductive disk 1212 reaches the inner wall surface of the cavity 113 is much smaller than the radial distance over which the conductive post 1211 reaches the inner wall surface of the cavity 113.

[0053] In some embodiments, as shown in FIG. 3, the microwave radiating element 122 may be offset away from the central axis of the inner conductor body 121 and positioned circumferentially outward of the aerosol-generating product 200 .

[0054] 4, the microwave radiating element 122 may include a probe. The probe may have an elongated shape, with one end of the probe fitted into the upper end (the end away from the conductive posts 1211) of the conductive disk 1212 of the inner conductor body 121 and the other end extending toward the open end 112 and into the slot 1435 of the receiving seat 14, with the axis of the probe being parallel to the axis of the conductive disk 1212 and offset from the axis of the conductive disk 1212. This allows the probe to be positioned outside the circumferential direction of the aerosol-generating product 200 to intensively heat a partial region in the circumferential direction of the aerosol-generating product 200.

[0055] Of course, the number of probes can be adjusted according to the actual situation and is not limited to 1. Correspondingly, the number of slots 1435 can be adjusted according to the number of probes.

[0056] In some embodiments, as shown in FIG. 3 , the microwave supply unit 13 may be a coaxial connector, one end of the microwave supply unit 13 is connected to the microwave generating unit by a coaxial coupling or a microstrip line, and the other end of the microwave supply unit 13 is attached to the outer conductor unit 11 and extends to the cavity 113 to form an ohmic contact with the cavity 113.

[0057] As shown in FIG. 4, the microwave supply unit 13 may include an inner conductor 131, an outer conductor 132, and a medium layer 133 interposed between the inner conductor 131 and the outer conductor 132.

[0058] The outer conductor 132 may be cylindrical, and both ends of the outer conductor 132 are open, so that the outer circumferential surface of the outer conductor 132 makes ohmic contact with the inner wall surface of the supply hole 117 during assembly.

[0059] The internal conductor 131 has a straight needle-like structure, one end of the internal conductor 131 is a connection end, which is located inside the external conductor 132 and is used to connect to the microwave generating unit to pass microwaves, and the other end of the internal conductor 131 is a supply end 1311, which is located outside the external conductor 132 and may be located in the cavity 113 during assembly and connected to the connection part 1151 to form good ohmic contact.

[0060] It should be understood that the supply end 1311 of the inner conductor 131 is not limited to making ohmic contact with the connecting portion 1151, but may directly form ohmic contact with the inner conductor body 121. Furthermore, the shape of the inner conductor 131 is not limited to a straight line, but may also be L-shaped (not shown). For example, the inner conductor 131 may include a first segment perpendicular to the central axis 142 of the cavity 113 and a second segment parallel to the central axis 142 of the cavity 113, the first segment being partially located within the outer conductor 132 and integrally connected to one end of the second segment, and the other end of the second segment being located outside the outer conductor 132 and making direct ohmic contact with the conductor end wall 115 of the outer conductor unit 11.

[0061] As shown in Figures 2 and 3, in some embodiments, the drive assembly 5 is attached to the receiving seat 14 and engages with the aerosol generating product 200, and the drive assembly 5 can drive the aerosol generating product 200 to rotate around the central axis 142 of the receiving chamber 141.

[0062] As shown in FIG. 8 , the drive assembly 5 includes a drive member and a transmission unit 52. The drive member is electrically connected to the control assembly 2, and the control assembly 2 controls whether the drive member operates. When the drive member operates, the drive member drives the transmission unit 52, which in turn drives the aerosol generating product 200 to rotate, thereby allowing the aerosol generating product 200 to rotate around its central axis. Naturally, the aerosol generating product 200 can also be rotated by manually driving the transmission unit 52. It should be understood that the drive motor 51 can rotate the aerosol generating product 200 by a predetermined angle each time the atomization medium is inhaled under the control of the control assembly 2. For example, the aerosol generating product 200 rotates 30° with each inhalation, and completes one full rotation after 12 inhalations. Naturally, the predetermined angle can be adjusted according to actual circumstances and is not limited to 30°, so it is not specifically limited herein.

[0063] The drive member is fixedly mounted to the mounting bracket 4, and the drive member may be a drive motor 51. The rotation axis 511 of the drive motor 51 is parallel to the central axis of the accommodation chamber 141. Optionally, the drive motor 51 may include a stepper motor.

[0064] As shown in Figures 8 and 9, the transmission unit 52 may include a driving member 521 attached to the rotating shaft 511 of the driving motor 51, and a driven member 522 attached to the receiving seat 14 and rotatable around the central axis 142 of the receiving seat 14, and the driving member 521 engages with the driven member 522 to transmit the power generated by the driving motor 51 to the driven member 522.

[0065] Alternatively, the transmission unit 52 may have a gear transmission structure and may include a driving gear (driving member 521) fixed to the rotation shaft 511 of the driving member and a driven gear (driven member 522) attached to the receiving seat 14. The driving gear can rotate synchronously with the rotation shaft 511 of the drive motor 51, the driven gear is rotatably attached to the receiving seat 14 and can rotate relative to the receiving seat 14, the driving gear and the driven gear mesh with each other, and the plane on which they are located is perpendicular to the central axis of the outer conductor unit 11, and the inner circumference of the driven gear abuts against the aerosol generating product 200 inserted in the receiving seat 14 and may be fixed relative to the aerosol generating product 200.

[0066] The driven gear has a plurality of teeth formed on its circumferential outermost portion for meshing with and connecting to the driving gear, and the driven gear further has one through hole 523 formed therein, which may be connected to the storage chamber 141 after assembly, and the aerosol-generating product 200 may extend into the storage chamber 141 through the through hole 523.

[0067] As shown in FIG. 10, the through-hole 523 includes a first hole segment 5231 and a second hole segment 5232 coaxially connected to the first hole segment 5231 .

[0068] The first hole segment 5231 is located above the receiving seat 14, and has a plurality of fixing teeth 5234 formed on its peripheral wall. The diameter formed by these fixing teeth 5234 is smaller than the outer diameter of the aerosol generating product 200 and is used to clamp the peripheral surface of the aerosol generating product 200 and fix the aerosol generating product 200 and the driven gear relative to each other, so that the aerosol generating product 200 can rotate synchronously with the driven gear. Optionally, the fixing teeth 5234 may be ratchet teeth, which are formed on the peripheral surface of the first hole segment 5231 at intervals in the same direction along the circumference.

[0069] The hole diameter of the second hole segment 5232 is larger than the hole diameter of the first hole segment 5231 and matches the outer diameter of the receiving portion 143, thereby forming a step between the first hole segment 5231 and the second hole segment 5232. During assembly, the second hole segment 5232 is attached to the outer periphery of the receiving portion 143, and the step surface abuts against the upper end of the receiving portion 143. Preferably, the second hole segment 5232 further has a groove 5235 formed in its peripheral wall around its periphery, the groove 5235 being annular and used to fit with a flange 1433 formed on the receiving portion 143. During assembly, the flange 1433 can be fitted into the groove 5235, and the size of the flange 1433 is slightly smaller than that of the groove 5235, forming a gap between the flange 1433 and the groove 5235, thereby allowing the driven gear to rotate relative to the receiving seat 14. The design of the groove 5235 and the flange 1433 not only ensures that the driven gear is securely attached to the accommodating portion 143, but also reduces the rotational contact area between the driven gear and the accommodating portion 143, thereby reducing frictional resistance during rotation.

[0070] Naturally, the driving gear and the driven gear may be directly connected by meshing, or may be connected by one or more driven gears for transmission interposed between the driving gear and the driven gear, and whether or not to install a driven gear and the number of gears to be installed can be determined by installing a driven gear and adjusting the number of driven gears based on factors such as the specified angle at which the aerosol generating product 200 rotates and the positional relationship between the driving member and the accommodating seat 14.

[0071] Alternatively, the transmission unit 52 may be a belt transmission unit (not shown), and may include a driving pulley (driving member 521), a driven pulley (driven member 522) and a belt, the plane on which the driving pulley and the driven pulley are located is perpendicular to the central axis of the accommodating chamber 141, the driving pulley is fixed to the rotating shaft 511 of the driving motor 51, the driven pulley is attached to the accommodating seat 14 and is located above the accommodating seat 14, and at the same time, the driven pulley has a through hole 523 and a through hole 524. 23 is provided with a plurality of fixed teeth 5234 (which may also refer to the fixed teeth 5234 formed on the movable part), and when the aerosol-generating product 200 is inserted into the accommodating seat 14 through the driven pulley, the driven pulley is fixed relative to the aerosol-generating product 200 by the plurality of fixed teeth 5234, and power can be transmitted to the driven pulley by the belt pulled by the driving pulley and the driven pulley, and the driven pulley drives the aerosol-generating product 200 to rotate synchronously.

[0072] Alternatively, the transmission unit 52 may be a chain transmission unit (not shown), and may include a driving pulley (driving member 521), a driven pulley (driven member 522) and a chain, wherein the plane on which the driving pulley and the driven pulley are located is perpendicular to the central axis of the accommodating chamber 141, the driving pulley is fixed to the rotating shaft 511 of the drive motor 51, the driven pulley is attached to the accommodating seat 14 and is located above the accommodating seat 14, and at the same time, the driven pulley has a through hole 523 and a plurality of fixed teeth 5234 (which may also refer to the fixed teeth 5234 formed on the movable part) installed in the through hole 523, and when the aerosol generating product 200 is inserted into the accommodating seat 14 through the driven pulley, the driven pulley is fixed relative to the aerosol generating product 200 by the plurality of fixed teeth 5234, and power can be transmitted to the driven pulley by the chain, and the driven pulley drives the aerosol generating product 200 to rotate synchronously.

[0073] Alternatively, the transmission unit 52 may be a ratchet transmission unit, which may include a swing link fixed to the rotation shaft 511 of the drive member, a ratchet connected to the swing link, and a ratchet cover attached above the receiving seat 14, the plane on which the ratchet cover lies is perpendicular to the central axis of the receiving chamber 141, and the ratchet cover is formed with a through-hole 523 and a plurality of fixed teeth 5234 (which may also refer to the fixed teeth 5234 formed on the movable part) disposed in the through-hole 523, so that when the aerosol generating product 200 is inserted into the receiving seat 14 through the ratchet cover, the ratchet cover is fixed relative to the aerosol generating product 200 by the plurality of fixed teeth 5234. As will be understood, the swing link causes the ratchet to swing back and forth, the ratchet moves the ratchet cover to perform intermittent movement in one direction, and the aerosol generating product 200 rotates synchronously with the ratchet cover.

[0074] In some embodiments, the mounting bracket 4 may be a metal bracket made of a metal material and has a thermally conductive effect. As shown in Figure 2, the mounting bracket 4 includes a first bracket portion to which the microwave heating assembly 1 can be attached and a second bracket portion to which the drive motor 51 of the drive assembly 5 can be attached.

Those skilled in the art can freely combine the above technical features and make various modifications and improvements without departing from the concept of the present invention.
