[0019] In the following description, specific details such as particular system configurations and technologies are presented for illustrative purposes, not limitation, to fully understand embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention can be realized in other embodiments without these specific details. In other circumstances, detailed descriptions of well-known systems, apparatus, circuits, and methods are omitted so as not to interfere with the description of the present invention.

[0020] The present invention comprises an aerosol generator 100, which generates an aerosol by heating an aerosol generating product 200 with microwaves to atomize it, and is used for inhalation or suction by the user.

[0021] In some embodiments, referring to Figure 1, the aerosol generator 100 may be formed in an elliptical cylindrical shape overall. Of course, the shape of the aerosol generator 100 may be other shapes and is not particularly limited herein.

[0022] Referring again to Figures 2 and 3, the aerosol generator 100 may include a microwave heating assembly 1, a microwave generating unit (not shown), a control assembly 2, a drive assembly 5, and a power supply assembly (not shown).

[0023] Of course, if necessary, the aerosol generator 100 may further include a housing 3 and a mounting bracket 4 provided inside the housing 3, as shown in Figures 1 and 2, and the microwave heating assembly 1, microwave generating unit and power supply assembly may be attached to the mounting bracket 4.

[0024] Here, 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. The control assembly 2 is used to control the operation of the microwave heating assembly 1, the microwave generating unit, and the drive assembly 5. The microwave generating unit generates a microwave signal and supplies microwaves to the microwave heating assembly 1. The microwave heating assembly 1 uses microwaves to perform localized circumferential heating of the aerosol generating product 200. The drive assembly 5 is used to rotate the aerosol generating product 200 relative to the microwave heating assembly 1, achieving stepped circumferential heating. In each rotational cycle, each time the aerosol generating product 200 is rotated and heated, the heated portion becomes a localized structure that has not been heated during that rotational cycle. This ensures consistency in taste throughout one rotational cycle of the aerosol and improves the user experience.

[0025] Furthermore, in conventional technology, the heating of the entire matrix segment of the aerosol generating product 200 is slow when initially heated. In contrast, in the present invention, the microwave heating assembly 1 focuses on heating localized areas in the circumferential direction of the aerosol generating product 200, reducing the area to be heated. As a result, even with the same power, the aerosol generator 100 can achieve a faster mist emission rate. Moreover, because the aerosol generator 100 heats only localized areas, the heating power can be lower than in conventional technology, resulting in greater energy savings.

[0026] For example, the control assembly 2 includes an airflow sensing switch 21, and each time suction occurs, the airflow sensing switch 21 senses a change in airflow and controls the drive assembly 5 to rotate the aerosol generating product 200 relative to the microwave heating assembly 1, thereby changing the area in which the aerosol generating product 200 is heated circumferentially.

[0027] Of course, the drive assembly 5 is not an essential component of the present invention, and in some embodiments, relative rotation between the aerosol generating product 200 and the microwave heating assembly 1 may be achieved by a manual control method.

[0028] In some embodiments, the appearance of the microwave heating assembly 1 is substantially cylindrical. Of course, the microwave heating assembly 1 is not limited to a cylindrical shape and may have other shapes such as a rectangular prism or an elliptical prism.

[0029] Referring together to Figures 3 and 4, the microwave heating assembly 1 may comprise an outer conductor unit 11, an inner conductor unit 12, a housing seat 14, and a microwave supply unit 13. The outer conductor unit 11 has a sealed end 111 and an open end 112 opposite the sealed end 111, defining a semi-sealed cavity 113. The inner conductor unit 12 includes an inner conductor body 121 and a microwave radiating element 122 joined to the inner conductor body 121. The inner conductor body 121 is connected to the sealed end 111 of the outer conductor unit 11, making ohmic contact with the end wall of the sealed end 111, forming a short-circuit end of the microwave heating assembly 1. The microwave radiating element 122 is located in the cavity 113 but does not contact the outer conductor unit 11, forming an open end of the microwave heating assembly 1. The microwave supply unit 13 is detachably attached to the outer conductor unit 11 and supplies microwaves generated by the microwave generation unit to the cavity 113, thereby forming a microwave field in the cavity 113 that can act on the aerosol generating product 200. The housing seat 14 is fixedly or detachably attached to the open end 112 of the outer conductor unit 11 and is used to define a housing cavity 141 for housing the aerosol generating product 200, the housing cavity 141 being located in the main region where the microwave field is formed.

[0030] Of course, the accommodating seat 14 is not an essential component in this invention. It is a preferred technical solution applied to this invention and can serve to protect the cavity 113 and the inner conductor body 121 from contamination by mist, or to minimize contamination. In other embodiments, the accommodating cavity 141 can be directly formed in the cavity 113. For example, without providing the accommodating seat 14, the aerosol generating product 200 can be directly inserted into the cavity 113 from the open end 112 of the outer conductor unit 11. In this case, the space occupied by the aerosol generating product 200 in the cavity 113 is the accommodating cavity 141.

[0031] As shown in Figure 3, the housing cavity 141 may include one central axis 142, and the aerosol generating product 200 (see Figure 8) may be cylindrical, and when inserted into the housing cavity 141, the central axis of the aerosol generating product 200 coincides with the central axis 142 of the housing cavity 141. The microwave radiating element 122 is positioned offset from the central axis 142 of the housing cavity 141, located on the outer circumference of the housing cavity 141, and is rotatable around the central axis 142 of the housing cavity 141 with respect to the aerosol generating product 200 provided in the housing cavity 141. It can be understood that the microwave radiating element 122 is rotatable around the central axis 142 of the housing cavity 141, or that the aerosol generating product 200 is rotatable around its central axis 142 in the housing cavity 141.

[0032] For example, the microwave radiating element 122 may be fixed to the outer conductor unit 11, and the aerosol generating product 200 may be rotatably mounted in the housing cavity 141. Preferably, the inner conductor body 121, the microwave radiating element 122, and the housing seat 14 are fixedly arranged in the cavity 113, and when the aerosol generating product 200 is inserted into the housing seat 14, the aerosol generating product 200 is fixed relative to the housing seat 14 in the axial direction, but the aerosol generating product 200 is rotatable around the central axis 142 of the housing cavity 141.

[0033] The microwave radiating element 122 is rotatable relative to the outer conductor unit 11, and the aerosol generating product 200 may be fixedly mounted in the housing cavity 141. Preferably, the microwave radiating element 122 and the inner conductor body 121 rotate synchronously. Here, the inner conductor body 121 and the microwave radiating element 122 are fixed relative to each other, and the inner conductor body 121 and the microwave radiating element 122 are fixed relative to the cavity 113 in the axial direction, the inner conductor body 121 and the microwave radiating element 122 are rotatable around the central axis 142 of the housing cavity 141, the microwave radiating element 122 is mounted in the circumferential direction of the housing cavity 141, the aerosol generating product 200 is fixedly inserted into the housing cavity 141, and when the aerosol generating product 200 is inserted into the housing seat 14, the microwave radiating element 122 is rotatable in the circumferential direction of the aerosol generating product 200. Alternatively, only the microwave radiating element 122 rotates. Here, the inner conductor body 121 is fixed to the sealed end 111 of the outer conductor unit 11, the microwave radiating element 122 is fixed relative to the inner conductor body 121 in the axial direction, the microwave radiating element 122 is provided in the circumferential direction of the housing cavity 141 and is rotatable about the central axis 142 of the housing cavity 141 relative to the inner conductor body 121, the aerosol generating product 200 is fixedly inserted into the housing cavity 141, and when the aerosol generating product 200 is inserted into the housing seat 14, the microwave radiating element 122 is rotatable in the circumferential direction of the aerosol generating product 200.

[0034] The microwave radiating element 122 may be rotatable relative to the outer conductor unit 11, and the aerosol generating product 200 is also rotatably provided in the housing cavity 141, and at least one of the rotation directions and speeds of the two may be different. Preferably, the inner conductor body 121 is fixed to the sealed end 111 of the outer conductor unit 11, the microwave radiating element 122 is fixed relative to the inner conductor body 121 in the axial direction, the microwave radiating element 122 is provided circumferentially in the housing cavity 141 and is rotatable about the central axis 142 of the housing cavity 141 relative to the inner conductor body 121, the housing seat 14 is fixedly attached to the outer conductor unit 11, the microwave radiating element 122 is located circumferentially in the housing cavity 141, and when the aerosol generating product 200 is inserted into the housing seat 14, the aerosol generating product 200 is fixed relative to the housing seat 14 in the axial direction, but the aerosol generating product 200 is rotatable about the central axis 142 of the housing cavity 141. When the aerosol generating product 200 is inserted into the housing seat 14, the microwave radiating element 122 and the aerosol generating product 200 can each rotate.

[0035] Next, the rotation direction of the aerosol generating product 200 relative to the microwave heating assembly 1 can be determined according to the actual needs, and may be rotated in a single direction, for example, only clockwise or counterclockwise, and the rotation direction can be switched. For example, it can be switched from clockwise rotation to counterclockwise rotation, or from counterclockwise rotation to clockwise rotation.

[0036] In some embodiments, as shown in Figures 4 and 5, the outer conductor unit 11 may include a conductor side wall 114, a conductor end wall 115, and a conductor protruding wall 116.

[0037] The conductor side wall 114 may be cylindrical, and the upper end of the conductor side wall 114 is designed to be open, forming the open end 112 of the outer conductor unit 11. The lower end of the conductor side wall 114 is also designed to be open, and the conductor end wall 115 is integrally sealed to the lower end of the conductor side wall 114, forming the sealed end 111 of the outer conductor unit 11.

[0038] The conductor protrusion wall 116 is integrally joined to the outer circumference of the conductor side wall 114, and the bottom surface of the conductor protrusion 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 conductor end wall 115.

[0039] Supply holes 117 are formed in the conductor sidewall 114 and the conductor convex wall 116, and the supply holes 117 penetrate straight through the conductor sidewall 114 and the conductor convex wall 116 along a direction perpendicular to the central axis of the conductor sidewall 114, and the formation of the supply holes 117 is used to insert the microwave supply unit 13 into the cavity 113. Of course, the supply holes 117 may be formed in other locations, for example, 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.

[0040] A protruding connection portion 1151 is formed on the inner end face of the conductor end wall 115 (the end face facing the open end 112 of the outer conductor unit 11). The connection portion 1151 works in cooperation with the microwave supply unit 13 to supply microwaves generated by the microwave supply unit 13 into the cavity 113.

[0041] The conductor sidewall 114 is provided with a first ventilation hole 1141 that connects the outside of the conductor sidewall 114 to the cavity 113. Preferably, the first ventilation hole 1141 and the drive assembly 5 are located on opposite sides of the conductor sidewall 114 in the circumferential direction.

[0042] As shown in Figure 5, the outer conductor unit 11 may further include a first fixing plate 118 and a second fixing plate 119 integrally joined to the outer circumference of the conductor side wall 114. The first fixing plate 118 and the second fixing plate 119 cooperate with the mounting bracket 4 to fix the entire outer conductor unit 11 to the mounting bracket 4. Preferably, 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 close 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.

[0043] In some embodiments, as shown in Figure 4, the central axis 142 of the housing cavity 141 does not have to coincide with the central axis of the inner conductor body 121, and may be offset away from the central axis of the inner conductor body 121. Preferably, the central axis 142 of the housing cavity 141 is parallel to the central axis of the inner conductor body 121. Of course, the housing cavity 141 may be coaxial with the inner conductor body 121, and the purpose of offsetting the housing cavity 141 is to more appropriately segment and heat the aerosol generating product 200 in the circumferential direction. There may be a gap between the bottom of the housing seat 14 and the top of the inner conductor body 121, and the two do not come into direct contact.

[0044] As shown in Figures 4 and 6, the housing seat 14 may include a fixed portion 144 attached to the open end 112 of the outer conductor unit 11 and a housing portion 143 provided at least partially in the cavity 113.

[0045] The housing section 143 may be cylindrical. Of course, the shape of the housing section 143 is not limited to cylindrical, but may be other shapes such as rectangular tubes. The housing section 143 and the cavity 113 are spaced apart in the circumferential direction, and the outer diameter of the housing section 143 is smaller than the inner diameter of the cavity 113, and the inner diameter of the housing section 143 matches the outer diameter of the aerosol generating product 200. The housing section 143 may include a housing bottom wall 1431 for supporting the aerosol generating product 200, and cylindrical housing side walls 1432 provided around the periphery of the housing bottom wall 1431, and the housing bottom wall 1431 and the housing side walls 1432 together form a housing cavity 141, which is cylindrical. A second ventilation hole 1434 is further formed in the housing side wall 1432 to communicate with the first ventilation hole 1141, and the second ventilation hole 1434 may be provided opposite the first ventilation hole 1141.

[0046] The fixing portion 144 may be annular in shape, integrally joined to the outer circumference of the housing side wall 1432, and may be close to the upper end of the housing 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) comes into contact with the open end 112 of the outer conductor unit 11, thereby attaching the housing seat 14 to the outer conductor unit 11 and restricting the downward movement of the housing seat 14.

[0047] The housing seat 14 further includes a slot 1435 formed in the housing section 143, the slot 1435 penetrating the housing bottom wall 1431 and extending in the housing side wall 1432 along a direction parallel to the central axis 142 of the housing cavity 141, and is used to cooperate with the microwave radiating element 122.

[0048] As shown in Figures 4 and 7, the housing seat 14 further includes an intake passage 1436 formed in the housing section 143, which not only introduces outside air to the bottom of the aerosol generating product 200 but can also trigger an airflow sensing switch 21. The intake passage 1436 may include a first ventilation passage formed in the housing bottom wall 1431 and a second ventilation passage formed in the housing side wall 1432, with a second ventilation hole 1434 provided in the housing side wall 1432 at a position corresponding to the second ventilation passage, and the second ventilation passage can communicate aerobically with the airflow sensing switch 21 via the second ventilation hole 1434. Preferably, the second ventilation passage and the slot 1435 are located on opposite sides of the housing seat 14 in the circumferential direction.

[0049] To make it easier to understand, as shown in Figure 8, when the aerosol generating product 200 is inserted into the housing seat 14, the intake passage 1436 and the interior of the aerosol generating product 200 work together to form an airflow passage 6, allowing outside air to flow from the intake passage 1436 to the bottom of the aerosol generating product 200, and then flow vertically upward into its interior from the bottom, finally reaching the top of the aerosol generating product 200.

[0050] In some embodiments, as shown in Figure 4, the inner conductor body 121 includes a conductor post 1211 and a conductor disk 1212 integrally bonded to the conductor post 1211.

[0051] The conductor post 1211 is cylindrical and can be installed coaxially within the cavity 113. Furthermore, the outer diameter of the conductor post 1211 is smaller than the inner diameter of the cavity 113. Of course, the conductor post 1211 is not limited to a cylindrical shape; it may also be a prismatic shape or other shapes. The upper end of the conductor post 1211 (the end closest to the open end 112 of the outer conductor unit 11) is a free end and extends toward the open end 112 of the outer conductor unit 11, while the lower end of the conductor post 1211 (the end furthest from the open end 112 of the outer conductor unit 11) is a fixed end and can be connected to the conductor end wall 115 of the outer conductor unit 11.

[0052] Preferably, the conductor post 1211 may include a mounting portion for attachment to the conductor end wall 115, which is screw-connected to the conductor end wall 115 to form a reliable ohmic contact. Of course, the conductor post 1211 may also be directly and integrally bonded to the conductor end wall 115.

[0053] The conductor disk 1212 is coaxially joined to the upper end of the conductor post 1211, and the outer diameter of the conductor disk 1212 is larger than the outer diameter of the conductor post 1211 and smaller than the diameter of the cavity 113. The radial distance from the conductor disk 1212 to the inner wall surface of the cavity 113 is much smaller than the radial distance from the conductor post 1211 to the inner wall surface of the cavity 113.

[0054] In some embodiments, as shown in Figure 3, the microwave radiating element 122 can be offset away from the central axis of the inner conductor body 121 and positioned circumferentially outward of the aerosol generating product 200.

[0055] As shown in Figures 3 and 4, the microwave radiating element 122 may include a probe, which may be elongated in shape, with one end of the probe fitted onto the upper end (the end away from the conductor post 1211) of the conductor disk 1212 of the inner conductor body 121, and the other end of the probe extending toward the open end 112 and inserted into the slot 1435 of the housing seat 14, and the axis of the probe being parallel to the axis of the conductor disk 1212 and offset away from the axis of the conductor disk 1212, so that the probe is positioned on the circumferential outer side of the aerosol generating product 200 and intensively heats a localized area in the circumferential direction of the aerosol generating product 200.

[0056] Of course, the number of probes installed can be adjusted according to the actual situation and is not limited to one. Therefore, the number of slots 1435 can be adjusted to match the number of probes installed.

[0057] In some embodiments, as shown in Figure 3, the microwave supply unit 13 may be a coaxial connector, one end of which is connected to the microwave generating unit via a coaxial coupling or microstrip line, and the other end of which is attached to the outer conductor unit 11 and inserted into the cavity 113, making ohmic contact with the cavity 113.

[0058] As shown in Figure 4, the microwave supply unit 13 may include an inner conductor 131, an outer conductor 132, and a dielectric layer 133 interposed between the inner conductor 131 and the outer conductor 132.

[0059] The outer conductor 132 may be cylindrical, and both ends of the outer conductor 132 are designed to be open. During assembly, the outer peripheral surface of the outer conductor 132 makes ohmic contact with the inner wall surface of the supply hole 117.

[0060] The inner conductor 131 has a straight, needle-like structure. One end of the inner conductor 131 is a connection end, located inside the outer conductor 132, and is connected to a microwave generating unit for introducing microwaves. The other end of the inner conductor 131 is a supply end 1311, located outside the outer conductor 132, and is located inside the cavity 113 during assembly, connecting to the connection part 1151, which can form good ohmic contact.

[0061] Of course, the supply end 1311 of the inner conductor 131 is not limited to ohmic contact with the connection part 1151, but may also be in direct ohmic contact with the inner conductor body 121. Furthermore, the shape of the inner conductor 131 is not limited to a straight shape, and the inner conductor 131 may be L-shaped (not shown). For example, the inner conductor 131 may include a first segment perpendicular to the central axis of the cavity 113 and a second segment parallel to the central axis of the cavity 113. The first segment portion is located on the outer conductor 132 and integrally connected to one end of the second segment, while the other end of the second segment is provided outside the outer conductor 132 and is in direct ohmic contact with the conductor end wall 115 of the outer conductor unit 11.

[0062] In some embodiments, as shown in Figure 3, the drive assembly 5 is attached to the housing seat 14 and cooperates with the aerosol generating product 200 to rotate the aerosol generating product 200 around the central axis 142 of the housing cavity 141.

[0063] As shown in Figure 8, the drive assembly 5 may include an active member and a transmission unit 52, the active member being electrically connected to the control assembly 2, the operation of the active member being controlled by the control assembly 2, the active member being able to generate power and transmit it to the transmission unit 52, the transmission unit 52 being able to fix the aerosol generating product 200, and the aerosol generating product 200 being able to rotate by the transmission of power by the transmission unit 52.

[0064] To make it clear, the drive motor 51, under the control of the control assembly 2, can rotate the aerosol generating product 200 by a predetermined angle each time the atomizing medium is aspirated. For example, with each aspirator, the aerosol generating product 200 rotates by an angle of 30°, and one cycle can be completed with 12 aspirators. Of course, this predetermined angle can be adjusted according to the actual situation and is not particularly limited herein.

[0065] The active member is fixedly attached to the mounting bracket 4, and the active member may be a drive motor 51, the rotation axis 511 of the drive motor 51 is parallel to the central axis 142 of the housing cavity 141. If necessary, the drive motor 51 may be a stepping motor.

[0066] As shown in Figures 8 and 9, the transmission unit 52 may include an active member 521 attached to the rotating shaft 511 of the drive motor 51, and a driven member 522 that is rotatable around the central axis 142 of the housing cavity 141 and attached to the housing seat 14. The active member 521 engages with the driven member 522 and transmits the power generated by the drive motor 51 to the driven member 522.

[0067] If necessary, as shown in Figures 8 and 9, the transmission unit 52 may be a gear transmission structure including an active gear (active member 521) fixed to the rotating shaft 511 of the drive motor 51 and a driven gear (driven member 522) attached to the housing seat 14. The active gear is capable of synchronous rotation following the rotating shaft 511 of the drive motor 51, and the driven gear is rotatably fitted into the housing seat 14 and rotatable relative to the housing seat 14. The active gear and the driven gear mesh with each other, and the plane in which they are located is perpendicular to the central axis 142 of the housing cavity 141. The inner circumference of the driven gear abuts against the aerosol generating product 200 inserted into the housing seat 14 and is fixed relative to the aerosol generating product 200.

[0068] Multiple teeth are formed on the outermost surface of the driven gear for meshing and connecting with the active gear, and the driven gear is further formed with a through hole 523 that can communicate with the housing cavity 141 after assembly, and the aerosol generating product 200 can be inserted into the housing cavity 141 through the through hole 523.

[0069] As shown in Figure 10, the through hole 523 includes a first hole segment 5231 and a second hole segment 5232 that is coaxially connected to the first hole segment 5231.

[0070] The first hole segment 5231 is located on the upper part of the housing seat 14, and a plurality of fixed teeth 5234 are formed on the circumferential wall of the first hole segment 5231. The diameter formed by these fixed teeth 5234 is smaller than the outer diameter of the aerosol generating product 200, and by gripping the circumferential surface of the aerosol generating product 200, the aerosol generating product 200 and the driven gear are relatively fixed, causing the aerosol generating product 200 to rotate synchronously in accordance with the driven gear. Preferably, these fixed teeth 5234 may be ratchet teeth and are formed on the circumferential surface of the first hole segment 5231 at intervals in the same direction along the circumference.

[0071] The hole diameter of the second hole segment 5232 is larger than that of the first hole segment 5231 and fits the outer diameter of the housing 143, creating a step between the first hole segment 5231 and the second hole segment 5232. During assembly, the second hole segment 5232 is fitted onto the outer circumference of the housing 143, and the stepped surface abuts against the upper end of the housing 143. Preferably, the second hole segment 5232 has a groove 5235 formed in its circumferential wall along its circumferential direction, and this groove 5235 is annular for fitting with a flange 1433 formed on the housing 143. During assembly, the flange 1433 can be fitted into the groove 5235, and the dimensions of the flange 1433 are slightly smaller than those of the groove 5235, so that the driven gear is rotatable relative to the fixed seat. The design of the groove 5235 and flange 1433 not only ensures that the driven gear is securely mounted in the housing 143, but also reduces the rotational contact area between the driven gear and the housing 143, thereby reducing frictional resistance during rotation.

[0072] Of course, the active gear and the driven gear may be directly meshed and connected, or they may be connected by one or more gears interposed between them and used for power transmission. Whether or not a driven gear is provided, and the number of gears to be installed, can be determined according to factors such as the predetermined angle at which the aerosol generating product 200 rotates and the positional relationship between the drive motor 51 and the housing seat 14.

[0073] Preferably, the transmission unit 52 may be a belt transmission unit 52 (not shown), and the transmission unit 52 may include an active wheel (active member 521), a driven wheel (driven member 522), and a belt, wherein the plane on which the active wheel and the driven wheel are located is perpendicular to the central axis 142 of the housing cavity 141, the active wheel is fixed to the rotating shaft 511 of the drive motor 51, and the driven wheel is attached to and positioned above the housing seat 14, and at the same time, the driven wheel has through holes 523 and a plurality of fixed teeth 5234 provided in the through holes 523, and when the aerosol generating product 200 is inserted into the housing seat 14 through the driven wheel, the driven wheel is fixed relative to the aerosol generating product 200 by the plurality of fixed teeth 5234, and power can be transmitted to the driven wheel by the belt stretched between the active wheel and the driven wheel, and the driven wheel rotates the aerosol generating product 200 synchronously.

[0074] Preferably, the transmission unit 52 may be a chain transmission unit 52 (not shown), and the transmission unit 52 may include an active wheel (active member 521), a driven wheel (driven member 522), and a chain, wherein the plane in which the active wheel and the driven wheel are located is perpendicular to the central axis 142 of the housing cavity 141, the active wheel is fixed to the rotating shaft 511 of the drive motor 51, and the driven wheel is attached to and positioned above the housing seat 14, and at the same time, the driven wheel has through holes 523 and a plurality of fixed teeth 5234 provided in the through holes 523, and when the aerosol generating product 200 is inserted into the housing seat 14 through the driven wheel, the driven wheel is fixed relative to the aerosol generating product 200 by the plurality of fixed teeth 5234, and power can be transmitted to the driven wheel by the chain, and the driven wheel rotates the aerosol generating product 200 synchronously.

[0075] Preferably, the transmission unit 52 may be a ratchet transmission unit 52, which may include a swing lever (active member 521) fixed to the rotating shaft 511 of the drive motor 51, a ratchet pawl connected to the swing lever, and a ratchet sleeve (driven member 522) mounted above the housing seat 14, wherein the plane on which the ratchet sleeve is located is perpendicular to the central axis 142 of the housing cavity 141, and the ratchet sleeve has a through hole 523 and a plurality of fixing teeth 5234 provided in the through hole 523, and when the aerosol generating product 200 is inserted into the housing seat 14 through the ratchet sleeve, the ratchet sleeve is fixed relative to the aerosol generating product 200 by the plurality of fixing teeth 5234. To make it easier to understand, the oscillating lever causes the ratchet pawl to oscillate back and forth, the ratchet pawl moves the ratchet sleeve, causing it to perform intermittent motion in one direction, and the aerosol generating product 200 rotates in sync with the ratchet sleeve.

[0076] In some embodiments, the mounting bracket 4 may be a metal bracket made of a metal material that has heat-conducting properties. 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.

[0077] As described above, the present invention, through the design of the drive assembly 5 and the cooperation between the drive assembly 5 and the housing seat 14, enables the aerosol generating product 200 inserted into the housing seat 14 to be automatically rotated by a predetermined angle around the central axis 142 of the housing cavity 141 each time the user inhales during the use of the device, thereby achieving stepwise heating by circumferential rotation. During one rotation cycle, each time the aerosol generating product 200 is rotated and heated, the heated portion becomes a localized structure that has not been heated during that rotation cycle, thereby ensuring consistency of taste throughout one rotation cycle of the aerosol.

[0078] Furthermore, this aerosol generator 100 can achieve a faster mist discharge rate and greater energy savings compared to conventional aerosol generators.

Those skilled in the art can freely combine the above technical features and make multiple modifications and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, any equivalent transformations and modifications made within the claims of the present invention should be included within the claims of the present invention.
