[0020] FIG. 1 and FIG. 2 show an aerosol generating device according to some embodiments of the present invention. The aerosol generating device uses microwaves to heat an aerosol generating product 20, atomize it to generate an aerosol, and enable a user to inhale it.

[0021] As shown in FIG. 1, in some embodiments, the aerosol generating device includes a microwave heating component 10, a microwave generating unit (not shown), a control component (not shown), and a power supply component (not shown). The power supply component is used to supply power to the microwave heating component 10, the microwave generating unit, and the control component, and the control component is used to control the operations of the microwave heating component 10 and the microwave generating unit. The microwave generating unit can generate a microwave signal and supply the microwave to the microwave heating component 10 by connecting to the microwave heating component 10. The microwave heating component 10 uses the microwave to heat the aerosol generating product 20.

[0022] In some embodiments, the microwave heating component 10 generally has a cylindrical shape. Of course, the microwave heating component 10 is not limited to a cylindrical shape and may have other shapes such as a prismatic shape or an elliptical cylindrical shape.

[0023] As shown in Figures 1 and 2, the microwave heating component 10 includes an outer conductor unit 1, an inner conductor unit 2, a microwave supply unit 3, a housing seat 4, and a sealing seat 5. The outer conductor unit 1 can be cylindrical and have a closed end 11 and an open end 12 opposite the closed end 11, defining a semi-sealed cavity 13. A housing cavity 40 for housing the aerosol-generating product 20 is formed within the cavity 13. The inner conductor unit 2 primarily serves as a microwave conduction unit. The inner conductor unit 2 is installed within the cavity 13 of the outer conductor unit 1 and can have good ohmic contact with the outer conductor unit 1, and is used to couple the energy introduced from the microwave supply unit 3 into the cavity 13.

[0024] The outer conductor unit 1 can be manufactured from a metallic material or other high electrical conductivity material and is used to confine microwave energy within the cavity 13. The shape of the outer conductor unit 1 includes, but is not limited to, a cylinder or a rectangular parallelepiped, and the dimensions of the outer shell can be adjusted according to the dimensions of the aerosol generating product 20.

[0025] Referring also to Figure 3, the outer conductor unit 1 may include a conductor side wall 14 and a conductor end wall 15. The conductor side wall 14 may be cylindrical, and its top end is designed to be open, forming the open end 12 of the outer conductor unit 1 described above. The bottom end of the conductor side wall 14 is also designed to be open, and the conductor end wall 15 is integrally sealed to the bottom end of the conductor side wall 14, forming the closed end 11 of the outer conductor unit 1 described above.

[0026] A supply hole 141 is formed in the conductor side wall 14. This supply hole 141 is formed straight through the conductor side wall 14 along a direction perpendicular to the central axis of the conductor side wall 14 and is used to insert and install the microwave supply unit 3 into the cavity 13. Of course, the supply hole 141 can also be formed in the conductor end wall 15, and the microwave supply unit 3 is inserted into the cavity 13 from below the microwave heating component 10.

[0027] The microwave supply unit 3 is detachably attached to the outer conductor unit 1 and is used to supply microwaves generated by the microwave generation unit to the cavity 13. This creates a microwave field within the cavity 13 that can act on the aerosol-generating product 20, and this microwave field acts on the aerosol-generating product 20 to achieve microwave heating.

[0028] One end of the microwave supply unit 3 is inserted into the cavity 13 through the supply hole 141 of the outer conductor unit 1 and makes ohmic contact with the inner conductor unit 2. In some embodiments, one side of the microwave supply unit 3 is connected to a microwave generator via a coaxial connector or microstrip wire. The other side extends into the cavity 13 and makes ohmic contact with the cavity 13. The microwave supply unit 3 is manufactured from a metallic material, preferably metallic aluminum or copper. Furthermore, its outer surface may be coated with silver or gold. As shown in Figure 2, in some embodiments, the microwave supply unit 3 includes an inner conductor 31, an outer conductor 32, and a media layer 33 interposed between the inner conductor 31 and the outer conductor 32.

[0029] The outer conductor 32 can be cylindrical, and both ends of the outer conductor 32 are designed to be open. During assembly, the outer peripheral surface of the outer conductor 32 makes ohmic contact with the inner wall surface of the supply hole 141.

[0030] The inner conductor 31 has a straight, needle-like structure. One end of the inner conductor 31 is a connection end, located inside the outer conductor 32, and is used to connect to the microwave generating unit to capture microwaves. The other end of the inner conductor 31 is a supply end 311, located outside the outer conductor 32, which can extend into the cavity 13 during assembly and form good ohmic contact with the inner conductor unit 2. Of course, the supply end 311 of the inner conductor 31 is not limited to ohmic contact with the inner conductor unit 2, but can also form direct ohmic contact with the outer conductor unit 1.

[0031] As can be understood, the shape of the inner conductor 31 is not limited to a straight line. The inner conductor 31 may be L-shaped (not shown), and for example, the inner conductor 31 may include a first stage perpendicular to the central axis of the cavity 13 and a second stage parallel to the central axis of the cavity 13. Part of the first stage is located on the outer conductor 32 and is integrally connected to one end of the second stage. The other end of the second stage is located outside the outer conductor 32 and is in direct ohmic contact with the conductor end wall 15 of the outer conductor unit 1.

[0032] As shown in Figures 2 and 3, the inner conductor unit 2 includes a radial structure 21 and an inner conductor main body 22. The radial structure 21 extends into the housing cavity 40 by sequentially penetrating the seal seat 5 and the housing seat 4, and the seal seat 5 and the housing seat 4 are press-fitted with the radial structure 21, respectively, to realize a double seal structure.

[0033] The inner conductor unit 2 is connected to the closed end 11 of the outer conductor unit 1 and is in ohmic contact with the conductor end wall 15, forming a short-circuit end of the microwave heating component 10. The radiating structure 21 is located within the cavity 13 but does not directly contact the outer conductor unit 1, forming an open end of the microwave heating component 10.

[0034] The inner conductor body 22 includes a conductor column 221, which is installed within the cavity 13, and the outer diameter of the conductor column 221 is smaller than the inner diameter of the outer conductor unit 1. The conductor column 221 includes a fixed end 2211 and a free end facing each other, the fixed end 2211 being fixed to the outer conductor unit 1 and in ohmic contact with the conductor end wall 15 of the outer conductor unit 1. As can be understood, in other embodiments, the fixed end 2211 can be integrally connected to the conductor end wall 15 of the outer conductor unit 1.

[0035] The conductor column 221 primarily serves as a microwave conduction mechanism and, in some embodiments, can be cylindrical. As can be understood, the conductor column 221 is not limited to a cylindrical shape and may be polyhedral or of other shapes. One end of the conductor column 221 away from the open end 12 of the outer conductor unit 1 is a fixed end 2211, which can be fixedly connected to the conductor end wall 15 of the outer conductor unit 1. The other end, closer to the open end 12, is a free end and extends toward the open end 12 of the outer conductor unit 1.

[0036] The inner conductor body 22 further includes a conductor plate 222, which is used to adjust the supply frequency (step impedance). The conductor plate 222 is not only used for microwave conduction, but can also increase its own inductance and capacitance, thereby lowering the resonant frequency, which is advantageous for further miniaturizing the dimensions of the cavity 13. The conductor plate 222 is disc-shaped and can be coaxially connected to the free end of the conductor column 221. The outer diameter of the conductor plate 222 is larger than the outer diameter of the conductor column 221, and the outer diameter of the conductor plate 222 is smaller than the diameter of the cavity 13. The radial distance from the conductor plate 222 to the inner wall surface of the cavity 13 is much smaller than the radial distance from the conductor column 221 to the inner wall surface of the cavity 13.

[0037] The radial structure 21 can be coupled to the free end of the conductor column 221. The radial structure 21 includes at least one probe, which may be elongated and positioned to extend parallel to the axis of the conductor column 221. In some embodiments, the probe can be embedded in the conductor column 221.

[0038] As shown in Figures 3 to 5, the housing seat 4 can be generally hollow cylindrical in shape, and the housing cavity 40 can be formed within the housing seat 4, and the housing cavity 40 is located in the main region where the microwave field is formed. The housing seat 4 also serves to protect the cavity 13 and the internal conductor unit 2 from contamination by mist, or to prevent contamination as much as possible.

[0039] The housing seat 4 includes a fixing portion 41 and a housing portion 42, and the fixing portion 41 of the housing seat 4 can be fixedly or detachably attached to the open end 12 of the outer conductor unit 1.

[0040] As shown in Figures 4 and 5, the housing section 42 includes a housing end wall 421 and a cylindrical housing side wall 422 surrounding the periphery of the housing end wall 421, the outer diameter of which is smaller than the inner diameter of the conductor side wall 14 of the outer conductor unit 1. A housing cavity 40 is formed between the housing end wall 421 and the housing side wall 422, and can house the aerosol-generating product 20. The housing end wall 421 is provided with a through hole 4211 for the radiating structure 21 to pass through, and the through hole 4211 penetrates in the axial direction of the outer conductor unit 1. The radiating structure 21 extends into the housing cavity 40 through the through hole 4211. When the aerosol-generating product 20 is placed in the housing cavity 40, the radiating structure 21 extends into the aerosol-generating product in the housing cavity 40 through the through hole 4211 and can heat the aerosol-generating product.

[0041] In some embodiments, the housing seat 4 further includes a plurality of elongated positioning ribs 44. These positioning ribs 44 are installed circumferentially and evenly spaced on the inside of the housing side wall 422. Each positioning rib 44 extends along a direction parallel to the axis of the housing cavity 40. These positioning ribs 44 can be used, on the one hand, to tighten the aerosol-generating product 20 inserted into the housing cavity 40, and on the other hand, a first intake passage is formed between each pair of adjacent positioning ribs 44, each extending longitudinally, thereby facilitating the intake of ambient air to the bottom of the aerosol-generating product 20 and further into the aerosol-generating product 20 to carry out the aerosol generated by microwave heating.

[0042] In some embodiments, the housing seat 4 further includes a plurality of elongated support ribs 45. These support ribs 45 are evenly spaced and radially distributed on the housing end wall 421. As understood, the support ribs 45 are used on the one hand to support the aerosol-generating product 20 and on the other hand to form a plurality of radial second intake passages. Each of these second intake passages communicates with these first intake passages, thereby facilitating the intake of ambient air to the bottom of the aerosol-generating product 20 and further into the aerosol-generating product 20 to carry out the aerosols generated by microwave heating.

[0043] As shown in Figure 4, the receiving seat 4 further includes a protrusion 43, which is positioned on the receiving end wall 421 and extends upward toward the opening end 12 along the periphery of the through hole 4211. This facilitates the radial structure 21 to penetrate the through hole 4211 and prevents liquid remaining at the bottom of the receiving seat 4 from flowing out of the through hole 4211.

[0044] Referring to Figures 3 and 4 together, when the medium is heated, the temperature can reach over 300°C. The through-hole 4211 at the bottom of the housing seat 4 and the radiating structure 21 are sealed by press-fit compounding, but prolonged operation at high temperatures gradually reduces the seal. If the housing seat 4 and the radiating structure 21 are in a dynamic seal compound, dirt will accumulate on the radiating structure 21 after prolonged operation, similarly causing seal deterioration. After the seal deteriorates, moisture generated during the heating process can easily enter the cavity 13 and come into contact with the conductor sidewall 14 of the outer conductor unit 1, which is at a relatively lower temperature, forming condensate. The condensate flows downward into the core of the cavity 13, causing contamination and affecting the normal operation of the device.

[0045] As shown in Figure 5, in some embodiments, to improve the sealing effect, the microwave heating component 10 further includes a sealing member 6. The sealing member 6 is installed on the housing end wall 421 and covers the through hole 4211, and the sealing member 6 is provided with a perforation 61. When the radiating structure 21 penetrates the perforation 61, the sealing member 6 press-fits with the radiating structure 21, preventing the already formed condensate from flowing to the core of the cavity 13. The sealing member 6 may also be a sealing ring, and the material of the sealing member 6 may include plastic, silicone rubber, etc. As can be seen, increasing the thickness of the housing end wall 421 can also make it more difficult for the condensate to flow into the cavity 13, thereby improving the sealing effect.

[0046] The material of the receiving seat 4 can include polymer materials, ceramic materials, metallic materials, or glass materials. Specifically, polymer materials can include polytetrafluoroethylene (PTFE), polyether ether ketone (PEEK), PPSU, PC, ABS, PP, etc. Ceramic materials can include alumina, zirconia, etc. In actual applications, polymer materials are preferred because they have advantages such as low cost and low thermal conductivity.

[0047] Referring together to Figures 2, 3, and 6, the seal seat 5 can be cylindrical and located within the cavity 13. The seal seat 5 is installed between the inner conductor body 22 and the housing seat 4, forming a housing cavity. The seal seat 5 includes a seal side wall 51 and a seal end wall 52, the seal side wall 51 being positioned to reduce the generation of condensate during the heating process. The seal side wall 51 can abut against the conductor side wall 14 of the outer conductor unit 1, effectively preventing the formation of condensate on the outer conductor unit 1. The seal seat 5 can be fixed to the inner conductor unit 2. The outer diameter of the seal seat 5 is less than or equal to the inner diameter of the outer conductor unit 1, and the inner diameter of the seal seat 5 is greater than the outer diameter of the housing side wall 422. The depth of the seal seat 5 can be equal to the depth of the housing 42.

[0048] As shown in Figures 3 and 6, a boss 53 can be provided at the bottom of the seal seat 5. The boss 53 is located on the end face of the seal end wall 52 of the seal seat 5 facing the housing seat 4 and extends toward the open end 12. As can be understood, an opening 54 corresponding to the through hole 4211 of the housing seat 4 is provided at the bottom of the seal seat 5. Specifically, the opening 54 may be located at the center of the boss 53. The boss 53 can relatively increase the height of the center of the bottom of the seal seat 5, increasing the sealing area between it and the radial structure 21 and preventing liquid remaining at the bottom of the seal seat 5 from flowing out through the opening 54.

[0049] Of course, the boss 53 is not an essential component in the present invention, but is applied as a preferred option. If the thickness of the sealing end wall 52 of the seal seat 5 is sufficiently thick, the boss 53 may not be provided. Therefore, in some embodiments, the sealing area between the seal seat 5 and the radial structure 21 can be increased by increasing the thickness of the sealing end wall 52.

[0050] As shown in Figure 2, in this embodiment, the sealing end wall 52 of the sealing seat 5 can abut against the housing end wall 421 of the housing seat 4. Of course, the thickness of the sealing end wall 52 can be adjusted according to the actual situation, and the sealing end wall 52 of the sealing seat 5 does not necessarily have to abut against the housing seat 4, and is not specifically limited here.

[0051] By adding a seal seat 5 between the inner conductor body 22 and the receiving seat 4, the press-fit combination of the seal seat 5 and the radiating structure 21 constitutes a static seal (relative to the receiving seat 4), preventing the already formed condensate from flowing to the core of the cavity 13. The thermal conductivity of the seal seat 5 is much lower than that of the outer conductor unit 1, which reduces heat conduction from the atomizing medium to the outside, indirectly improving energy utilization. Therefore, the temperature of the seal seat 5 is relatively higher than that of the outer conductor unit 1, making it difficult for condensate to form on it.

[0052] As described above, the present invention has a double seal structure, which includes a first layer seal formed between the receiving seat 4 and the radial structure 21, and a second layer seal formed between the seal seat 5 and the radial structure 21.

[0053] As shown in Figure 2, the receiving seat 4 is at least partially located within the receiving cavity of the sealing seat 5, and the receiving seat 4 can move axially up and down relative to the sealing seat 5, thereby giving the receiving seat 4 the function of lifting the aerosol-generating product 20. Of course, the receiving seat 4 and the sealing seat 5 may be fixed relative to each other. Regardless of whether the receiving seat 4 has the function of lifting the aerosol-generating product 20, i.e., whether the receiving seat 4 is movable or not, the sealing seat 5 remains consistently stationary. The sealing effect of the double sealing structure is better because the aerosol and condensate must first break through the seal between the receiving seat 4 and the radiating structure 21 and the seal between the sealing seat 5 and the radiating structure 21 and then flow into the core of the cavity 13.

[0054] As should be understood, the above embodiments illustrate preferred embodiments of the present invention, and while their description is specific and detailed, it should not be understood that this limits the scope of the claims of the present invention. Those skilled in the art may freely combine the above technical features and make several modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made within the same scope as the claims of the present invention shall be included within the claims of the present invention.
