Description

Technical Field

[0001] (Cross - reference to Related Applications) This application claims the priority of a Chinese patent application with an application number of 202111219813.6 and an invention title of "Aerosol Fixing Device and Aerosol Generating Device", which was filed with the China National Intellectual Property Administration on October 20, 2021, and also claims the priority of a Chinese patent application with an application number of 202122524208.1 and an invention title of "Aerosol Fixing Device and Aerosol Generating Device", which was filed with the China National Intellectual Property Administration on October 20, 2021. All of its content is incorporated herein by reference.

[0002] This application relates to the technical field of aerosols, specifically to aerosol fixing devices and aerosol generating devices.

Background Art

[0003] Microwave heating has the advantages of high heating efficiency and fast aerosol generation.

[0004] In the prior art, when directly inserting an aerosol generation substrate at the bottom of a coaxial cavity, since the microwave electromagnetic field in the part near the top of the conductor column in the cavity is strong, the aerosol generation substrate located in this part can be heated and sufficiently carbonized. However, since the microwave electromagnetic field in the part far from the top of the conductor column is weak, the heating of the aerosol generation substrate located in this part becomes non - uniform and the carbonization is incomplete. As a result, the meaning of microwave heating is lost and the utilization rate of the aerosol generation substrate is reduced.

Summary of the Invention

Problems to be Solved by the Invention

[0005] This application aims to solve at least one of the technical problems existing in the prior art.

Means for Solving the Problems

[0006] Therefore, a first aspect of the present application provides an aerosol immobilization device.

[0007] A second aspect of the present application provides an aerosol generator.

[0008] An aerosol fixing device according to a first aspect of the present application includes a mounting base including an atomizing cavity for containing an aerosol generating substrate, a microwave introduction structure provided on the mounting base with an output terminal located inside the atomizing cavity, and a conductor member provided on the mounting base with at least a portion located on the side wall of the atomizing cavity.

[0009] The aerosol fixing device according to the present invention includes a mounting base, a microwave introduction structure, and a conductive member. The mounting base includes an atomizing cavity, which mounts and fixes an aerosol generating substrate. Specifically, at least a portion of the aerosol generating substrate is located inside the atomizing cavity and can generate an aerosol by receiving heat. The microwave introduction structure is provided on the mounting base, and its output terminal is located inside the atomizing cavity. The microwave introduction structure introduces microwaves into the atomizing cavity to heat the aerosol generating substrate located inside the atomizing cavity. Furthermore, heating the aerosol generating substrate with microwaves enables rapid and efficient heating of the aerosol generating substrate, and can further improve the aerosol generation efficiency and generation speed.

[0010] In particular, during the process of generating aerosols, the magnetic field strength is strongest at the output end of the microwave introduction structure, while the magnetic field strength is weaker at the remaining locations. Therefore, this invention ensures that a conductive member is provided on the mounting base, and that at least a portion of the conductive member is provided on the side wall of the atomization cavity. In this way, this invention can change the magnetic field distribution within the atomization cavity using the conductive member, and furthermore, achieve uniform heating of the aerosol generation substrate within the atomization cavity. Alternatively, this invention only requires that at least a portion of the conductive member be provided on the side wall of the atomization cavity.

[0011] Specifically, in the process of generating aerosols, there is a strong electromagnetic field near the output end of the microwave introduction structure. The interaction between microwaves and different materials is essentially a direct interaction between the microwave electromagnetic field and the material. The high-frequency alternating electric field causes repeated polarization and violent motion of free or bound charges within the metallic material, resulting in collisions, friction, and internal wear between molecules, ultimately converting microwave energy into thermal energy. Therefore, in this invention, a conductive member is provided on the mounting base, and the conductive member is a good conductor. During microwave heating, eddy currents within the surface layer of the conductive member concentrate on the surface of the conductive member due to the skin effect, generating a coupling effect with the microwaves. The conductive member converts microwave energy into thermal energy, thereby more effectively heating the aerosol generating substrate and ensuring effective and uniform heating of the entire aerosol generating substrate.

[0012] Therefore, in this invention, a conductive member is provided on the mounting base, at least a portion of the conductive member is located on the side wall of the atomization cavity, and furthermore, by changing the magnetic field distribution strength within the atomization cavity with the conductive member, efficient heating of the aerosol generating substrate by microwaves can be ensured, while uniform heating of the aerosol generating substrate by microwaves can be ensured.

[0013] In some possible designs, the conductive member extends in the height direction of the atomization cavity.

[0014] In this design, an open end is provided at the top of the atomizing cavity, and the aerosol generating substrate may be inserted into the atomizing cavity from the open end. In this application, the conductive member extends along the height direction of the atomizing cavity such that its extending direction is the same as the insertion direction of the aerosol generating substrate. In this way, during the process of generating aerosols, the conductive member changes the magnetic field distribution strength within the atomizing cavity, ensuring that the magnetic field is uniformly distributed in the height direction of the atomizing cavity, and further achieving uniform and efficient heating of the aerosol generating substrate in the height direction of the atomizing cavity.

[0015] In several possible designs, one end of the conductor is provided at the bottom wall of the atomizing cavity, and the ratio of the dimensions of the conductor to the dimensions of the aerosol-generating substrate in the height direction of the atomizing cavity is 1 / 3 or less.

[0016] In this design, one end of the conductor is provided on the bottom wall of the atomization cavity, and the other end extends toward the open end at the top of the atomization cavity. Furthermore, in the height direction of the atomization cavity, the ratio of the dimensions of the conductor to the dimensions of the aerosol generating substrate is 1 / 3 or less. By rationally setting the dimensions of the conductor in the height direction of the atomization cavity in this way, the intensity distribution of the magnetic field within the atomization cavity is made more rational, and furthermore, uniform and efficient heating of the aerosol generating substrate by microwaves in the height direction of the atomization cavity is improved. In addition, the minimum ratio of the dimensions of the conductor to the dimensions of the aerosol generating substrate in the height direction of the atomization cavity can be designed according to actual needs, but is not limited here.

[0017] In several possible designs, the number of conductive members is at least two, and these at least two conductive members are distributed along the circumferential side of the atomization cavity.

[0018] In this design, there are at least two conductive members. The at least two conductive members are distributed along the circumferential side of the atomization cavity, specifically, the at least two conductive members are uniformly distributed along the circumferential side of the atomization cavity. In particular, during the process of generating aerosols, each conductive member can heat the aerosol generating substrate. Therefore, by distributing at least two conductive members along the circumferential side of the atomization cavity, this invention ensures that microwaves uniformly and efficiently heat the aerosol generating substrate on the circumferential side of the atomization cavity.

[0019] In several possible designs, the conductive member is located on the inner wall of the atomization cavity, and / or on the outer wall of the atomization cavity.

[0020] In this design, the conductive member may be provided on the inner wall of the atomizing cavity, on the outer wall of the atomizing cavity, or on both the inner and outer walls of the atomizing cavity. The specific position of the conductive member can be designed according to the actual situation. For example, it can be designed based on the volume of the atomizing cavity. If the volume of the atomizing cavity is small, the conductive member can be provided on the outer wall of the atomizing cavity to avoid the conductive member further occupying space within the atomizing cavity. If the volume of the atomizing cavity is large, the conductive member can be provided on the inner wall of the atomizing cavity to directly and efficiently heat the aerosol generating substrate with the conductive member.

[0021] In several possible designs, the conductive members include metal strips distributed in strip form along the sidewalls of the atomization cavity and extending toward the top of the atomization cavity.

[0022] In this design, the conductive members include metal strips distributed in a strip-like manner along the side walls of the atomization cavity and extending from the bottom wall of the atomization cavity toward the open end at the top of the atomization cavity. In particular, the metal strips are good conductors and can further change the magnetic field distribution within the atomization cavity, ensuring efficient heating of the aerosol-generating substrate by microwaves, while also ensuring uniform heating of the aerosol-generating substrate by microwaves.

[0023] Furthermore, in the height direction of the atomizing cavity, the ratio of the dimensions of the metal strip to the dimensions of the aerosol generating substrate is 1 / 3 or less, and the conductive member includes at least two metal strips distributed at intervals along the circumferential side of the atomizing cavity.

[0024] In some possible designs, the conductive members include metal coils that are spirally distributed along the sidewalls of the atomization cavity and extend toward the top of the atomization cavity.

[0025] In this design, the conductor member includes a metal coil that spirally distributes on the side wall of the atomization cavity and extends from the bottom wall of the atomization cavity towards the open end at the top of the atomization cavity. In particular, the metal coil is a good conductor and can further change the magnetic field distribution in the atomization cavity, while ensuring efficient heating of the aerosol generation substrate by microwaves and ensuring uniform heating of the aerosol generation substrate by microwaves.

[0026] Also, in the height direction of the atomization cavity, the ratio of the dimension of the metal coil to the dimension of the aerosol generation substrate is 1 / 3 or less. Further, the conductor member includes at least two metal coils that are spaced apart and distributed along the circumferential side of the atomization cavity. Also, in the height direction of the atomization cavity, the distance between two adjacent spiral coils is equal.

[0027] In some possible designs, the conductor member includes a first metal layer provided on the side wall of the atomization cavity, and at least a part of the first metal layer is provided with a hollowed-out area.

[0028] In this design, the conductor member includes a first metal layer. The first metal layer distributes on the side wall of the atomization cavity and extends from the bottom wall of the atomization cavity towards the open end at the top of the atomization cavity. Also, a hollowed-out area is provided in the first metal layer, and the magnetic field distribution in the atomization cavity can be further adjusted. In particular, the first metal layer is a good conductor and can further change the magnetic field distribution in the atomization cavity, while ensuring efficient heating of the aerosol generation substrate by microwaves and ensuring uniform heating of the aerosol generation substrate by microwaves.

[0029] Also, in the height direction of the atomization cavity, the ratio of the dimension of the first metal layer to the dimension of the aerosol generation substrate is 1 / 3 or less.

[0030] In some possible designs, convex portions are provided on the inner wall of the atomization cavity.

[0031] In this design, a protrusion is provided on the inner wall of the atomizing cavity. The protrusion is provided on the inner wall of the atomizing cavity and can come into contact with the aerosol generating substrate during operation. In this way, during the process of aerosol generation, there is a certain gap between the aerosol generating substrate and the inner wall of the atomizing cavity, and furthermore, the aerosol generated in the atomizing cavity can be easily discharged smoothly from the atomizing cavity through the gap.

[0032] In several possible designs, the microwave introduction structure is drilled into the bottom wall of the atomization cavity.

[0033] In this design, the microwave introduction structure is drilled into the bottom wall of the atomization cavity. The input end of the microwave introduction structure is located outside the atomization cavity, and the output end of the microwave introduction structure is located inside the atomization cavity. In this way, during use, the microwave introduction structure can introduce external microwaves into the atomization cavity to heat the aerosol generation substrate inside the atomization cavity. Specifically, the microwave introduction structure is drilled at the center of the bottom wall of the atomization cavity.

[0034] In some possible designs, the microwave introduction structure is integrated with the mounting base.

[0035] In this design, the microwave introduction structure is an integral part of the mounting base. This eliminates the need to connect the microwave introduction structure and the mounting base using connecting members, while ensuring the connection strength between the microwave introduction structure and the mounting base, and further improving the service life of the aerosol fixing device.

[0036] In some possible designs, the dimensions of some microwave introduction structures located within the atomization cavity are smaller than the dimensions of the aerosol generation substrate in the height direction of the atomization cavity.

[0037] In this design, the dimensions of a portion of the microwave introduction structure located within the atomization cavity are smaller than the dimensions of the aerosol generating substrate in the height direction of the atomization cavity. That is, during use, after the aerosol generating substrate is inserted into the atomization cavity, the output end of the microwave introduction structure is inserted into the interior of the aerosol generating substrate, and it is ensured that the output end of the microwave introduction structure does not expose itself to the aerosol generating substrate. In this way, the output end of the microwave introduction structure can heat the interior of the aerosol generating substrate.

[0038] Furthermore, the output terminal of the microwave introduction structure is located inside the aerosol generating substrate to heat the internal area of ​​the aerosol generating substrate, while the conductive member is located outside the aerosol generating substrate and also on the periphery of the aerosol generating substrate to heat the periphery of the aerosol generating substrate. In this way, the cooperation between the microwave introduction structure and the conductive member enables full-surface heating of the aerosol generating substrate, ensuring heating efficiency and heating uniformity for the aerosol generating substrate.

[0039] An aerosol generator according to a second aspect of the present application includes a housing having a resonant cavity inside, a microwave assembly provided in the housing for supplying microwaves into the resonant cavity, a resonant column whose first end is connected to the cavity bottom wall of the resonant cavity, and an aerosol fixing device of any of the above designs, wherein at least a portion of the aerosol fixing device is provided in the resonant cavity, and the input end of the microwave introduction structure is connected to the second end of the resonant column.

[0040] The aerosol generator according to this application includes an aerosol fixing device of any of the above designs, and therefore possesses all the effects and advantages of the above aerosol fixing device, which will not be described in detail here.

[0041] The aerosol generator further includes a housing, a microwave assembly, and a resonant column. A resonant cavity is provided within the housing, and the microwave assembly is provided within the housing and can supply microwaves into the resonant cavity when in operation. The resonant column is provided within the resonant cavity, and its first end is connected to the cavity bottom wall of the resonant cavity. After the aerosol fixing device is installed, at least a portion of the aerosol fixing device is located within the resonant cavity, and the input end of the microwave introduction structure is connected to the second end of the resonant column. In this way, heating of the aerosol generation substrate in the atomization cavity by microwaves supplied into the resonant cavity can be ensured.

[0042] In some possible designs, the aerosol generator further includes a mounting groove provided at the second end of the resonant column, and the input end of the microwave introduction structure is connected to the mounting groove.

[0043] In this design, the aerosol generator further includes a mounting groove. The mounting groove is provided at the second end of the resonant column and is provided in accordance with the resonant column. When mounting the aerosol fixing device, the positioning of the aerosol fixing device is ensured by positioning at least a portion of the aerosol fixing device within the resonant cavity and inserting the introduction end of the microwave introduction structure into the mounting groove, while also ensuring electrical connection between the microwave introduction structure and the resonant column.

[0044] In some possible designs, the dimensions of some mounting bases located within the resonant cavity in the height direction of the aerosol generator are greater than the dimensions of the aerosol generation substrate.

[0045] In this design, the dimensions of some of the mounting bases located within the resonant cavity in the height direction of the aerosol generator are greater than or equal to the dimensions of the aerosol generating substrate. In this way, it is possible to ensure that the aerosol generating substrate is completely located inside the mounting bases during use, and that the aerosol generating substrate is completely located inside the resonant cavity.

[0046] In several possible designs, the microwave assembly includes a microwave supply structure provided in a housing, with its output end directed toward the bottom wall or resonant column of a resonant cavity, and a microwave radiation source connected to the input end of the microwave supply structure.

[0047] In this design, the microwave assembly includes a microwave supply structure and a microwave radiation source. The microwave supply structure is housed in a housing, with its output end facing the bottom wall or resonant column of the resonant cavity and its input end connected to the microwave radiation source. Thus, when the aerosol generator is operating, microwaves generated by the microwave radiation source are supplied into the resonant cavity via the microwave supply structure.

[0048] Specifically, the resonant column can function as a conductor and may be made of a metallic material; for example, the resonant column may be made of copper, aluminum, iron, or an alloy thereof. The resonant column transmits microwaves and improves the transmission speed of microwaves, thereby reducing attenuation as the microwaves conduct within the resonant cavity.

[0049] In some possible designs, the housing is a metal housing, or a second metal layer is provided on the inner wall of the housing.

[0050] In this design, a metal housing may be used. Alternatively, a non-metallic housing may be used, and the inner wall of the housing may have a second metal layer.

[0051] In some possible designs, the resonant column is a conductive column, or a third metal layer is provided on the outer wall of the resonant column.

[0052] In this design, the resonant column may be a conductive column. Alternatively, the resonant column may be a non-conducting column, and a third metal layer may be provided on the outer wall of the resonant column.

[0053] Specifically, the resonant column is electrically connected to the housing, while the conductor member is not electrically connected to the resonant column.

[0056] The present application will be described in more detail below with reference to the drawings and specific embodiments in order to provide a clearer understanding of its objectives, features, and advantages. The embodiments and features described herein can be combined with each other, as long as they do not contradict each other.

[0057] Many specific details are provided in the following description in order to fully understand the present application; however, since the present application can be implemented in forms other than those described herein, the scope of protection is not limited to the specific embodiments disclosed below.

[0058] Hereinafter, with reference to Figures 1 to 8, aerosol fixing devices 100 and aerosol generators 200 according to several embodiments of the present application will be described.

[0059] A first embodiment of the present invention provides an aerosol fixing device 100 including a mounting base 102, a microwave introduction structure 106, and a conductor member 108.

[0060] As shown in Figures 1, 2, and 3, the mounting base 102 includes an atomizing cavity 104, to which the aerosol generating substrate 300 is attached and fixed. Specifically, at least a portion of the aerosol generating substrate 300 is located inside the atomizing cavity 104 and can generate aerosols by receiving heat. The microwave introduction structure 106 is provided on the mounting base 102, and the output terminal of the microwave introduction structure 106 is located inside the atomizing cavity 104. The microwave introduction structure 106 introduces microwaves into the atomizing cavity 104 to heat the aerosol generating substrate 300 located inside the atomizing cavity 104. Furthermore, by heating the aerosol generating substrate 300 with microwaves, rapid and efficient heating of the aerosol generating substrate 300 can be achieved, and the aerosol generation efficiency and generation speed can be improved.

[0061] In particular, during the process of generating aerosols, the magnetic field strength is strongest at the output end of the microwave introduction structure 106, while the magnetic field strength is weaker at the remaining locations. Therefore, as shown in Figures 4 and 5, the present invention ensures that a conductive member 108 is provided on the mounting base 102, and that at least a portion of the conductive member 108 is provided on the side wall 110 of the atomization cavity 104. In this way, the present invention can change the magnetic field distribution within the atomization cavity 104 using the conductive member 108, and furthermore, achieve uniform heating of the aerosol generation substrate 300 within the atomization cavity 104.

[0062] Specifically, in the process of generating aerosols, there is a strong electromagnetic field near the output end of the microwave introduction structure 106. The interaction between microwaves and different materials is essentially a direct interaction between the microwave electromagnetic field and the material. The high-frequency alternating electric field causes repeated polarization and violent motion of free or bound charges within the metallic material, resulting in collisions, friction, and internal wear between molecules, ultimately converting microwave energy into thermal energy.

[0063] Therefore, as shown in Figures 4 and 5, in this application, a conductor member 108 is provided on the mounting base 102, and the conductor member 108 is a good conductor. When microwave heating occurs, eddy currents in the surface layer of the conductor member 108 concentrate on the surface of the conductor member 108 due to the skin effect, generating a coupling effect with microwaves. The conductor member 108 converts microwave energy into thermal energy, thereby more effectively heating the aerosol generating substrate 300 and ensuring effective and uniform heating of the entire aerosol generating substrate 300.

[0064] Therefore, as shown in Figures 4 and 5, in this embodiment, a conductor member 108 is provided on the mounting base 102, at least a portion of the conductor member 108 is located on the side wall 110 of the atomization cavity 104, and by changing the magnetic field distribution strength within the atomization cavity 104 with the conductor member 108, efficient heating of the aerosol generating substrate 300 by microwaves can be ensured, while uniform heating of the aerosol generating substrate 300 by microwaves can be ensured.

[0065] Specifically, as shown in Figures 1, 2, and 3, during use, the aerosol generating substrate 300 is provided inside the mounting rod 400 and inserted into the atomizing cavity 104 via the mounting rod 400.

[0066] A second embodiment of the present invention provides an aerosol fixing device 100, which is based on the first embodiment and further, as shown in Figures 4 and 5, has an open end at the top of the atomizing cavity 104, and the aerosol generating substrate 300 may be inserted into the atomizing cavity 104 from the open end.

[0067] In this embodiment, the conductive member 108 extends along the height direction of the atomizing cavity 104 such that its extension direction is the same as the insertion direction of the aerosol generating substrate 300. In this way, during the process of aerosol generation, the conductive member 108 changes the magnetic field distribution strength within the atomizing cavity 104, ensuring that the magnetic field is uniformly distributed in the height direction of the atomizing cavity 104, and further achieving uniform and efficient heating of the aerosol generating substrate 300 in the height direction of the atomizing cavity 104.

[0068] In this embodiment, as shown in Figures 4 and 5, one end of the conductor member 108 is provided on the bottom wall 112 of the atomizing cavity 104, and the other end extends toward the open end at the top of the atomizing cavity 104. In addition, in the height direction of the atomizing cavity 104, the ratio of the dimensions of the conductor member 108 to the dimensions of the aerosol generating substrate 300 is 1 / 3 or less.

[0069] In this way, by rationally setting the dimensions of the conductor member 108 in the height direction of the atomization cavity 104, the intensity distribution of the magnetic field within the atomization cavity 104 is made more rational, and furthermore, uniform and efficient heating of the aerosol generating substrate 300 by microwaves in the height direction of the atomization cavity 104 is improved. In addition, the minimum ratio of the dimensions of the conductor member 108 to the dimensions of the aerosol generating substrate 300 in the height direction of the atomization cavity 104 can be designed according to actual needs, but is not limited here.

[0070] A third embodiment of the present invention provides an aerosol fixing device 100, which is based on the first embodiment and further comprises at least two conductive members 108, as shown in Figures 4 and 5. The at least two conductive members 108 are distributed along the circumferential side of the atomizing cavity 104, specifically, the at least two conductive members 108 are uniformly distributed along the circumferential side of the atomizing cavity 104. In particular, during the process of generating aerosols, each conductive member 108 can heat the aerosol generating substrate 300.

[0071] Therefore, in this embodiment, at least two conductive members 108 are distributed along the circumferential side of the atomizing cavity 104, ensuring that microwaves uniformly and efficiently heat the aerosol generating substrate 300 on the circumferential side of the atomizing cavity 104.

[0072] Specifically, the number of conductive members 108 is 2 to 10, preferably 2 to 4.

[0073] A fourth embodiment of the present invention provides an aerosol fixing device 100, which, based on the first embodiment, further shows that the conductive member 108 may be provided on the inner wall of the atomizing cavity 104, on the outer wall of the atomizing cavity 104, or on both the inner and outer walls of the atomizing cavity 104, as shown in Figures 4 and 5.

[0074] Specifically, the installation position of the conductor member 108 can be designed according to the actual situation. For example, it can be designed based on the volume of the atomization cavity 104. If the volume of the atomization cavity 104 is small, the conductor member 108 can be installed on the outer wall of the atomization cavity 104 to avoid the conductor member 108 further occupying space within the atomization cavity 104. If the volume of the atomization cavity 104 is large, the conductor member 108 can be installed on the inner wall of the atomization cavity 104 to directly and efficiently heat the aerosol generating substrate 300 with the conductor member 108.

[0075] Based on the first to fourth embodiments, the conductor member 108 further includes a metal strip, as shown in Figure 4. The metal strip is distributed in a strip-like manner along the side wall 110 of the atomizing cavity 104 and extends from the bottom wall 112 of the atomizing cavity 104 toward the open end at the top of the atomizing cavity 104. In particular, the metal strip is a good conductor and can further change the magnetic field distribution within the atomizing cavity 104, ensuring efficient heating of the aerosol generating substrate 300 by microwaves, while also ensuring uniform heating of the aerosol generating substrate 300 by microwaves.

[0076] Furthermore, in the height direction of the atomizing cavity 104, the ratio of the dimensions of the metal strip to the dimensions of the aerosol generating substrate 300 is 1 / 3 or less. The conductive member 108 includes at least two metal strips, and the at least two metal strips are distributed at intervals along the circumferential side of the atomizing cavity 104.

[0077] Based on the first to fourth embodiments, the conductor member 108 further includes a metal coil, as shown in Figure 5. The metal coil is spirally distributed on the side wall 110 of the atomizing cavity 104 and extends from the bottom wall 112 of the atomizing cavity 104 toward the open end at the top of the atomizing cavity 104. In particular, the metal coil is a good conductor and can further change the magnetic field distribution within the atomizing cavity 104, ensuring efficient heating of the aerosol generating substrate 300 by microwaves, while also ensuring uniform heating of the aerosol generating substrate 300 by microwaves.

[0078] Furthermore, in the height direction of the atomizing cavity 104, the ratio of the dimensions of the metal coil to the dimensions of the aerosol generating substrate 300 is 1 / 3 or less. The conductor member 108 includes at least two metal coils, and these at least two metal coils are distributed at intervals along the circumferential side of the atomizing cavity 104. In addition, in the height direction of the atomizing cavity 104, the distance between two adjacent helical coils is equal.

[0079] Based on the first to fourth embodiments, the conductor member 108 further includes a first metal layer (not shown). The first metal layer is distributed on the side walls 110 of the atomizing cavity 104 and extends from the bottom wall 112 of the atomizing cavity 104 toward the open end at the top of the atomizing cavity 104. The first metal layer may also have perforated regions to further adjust the magnetic field distribution within the atomizing cavity 104. In particular, the first metal layer is a good conductor and can further change the magnetic field distribution within the atomizing cavity 104, ensuring efficient heating of the aerosol generating substrate 300 by microwaves, while also ensuring uniform heating of the aerosol generating substrate 300 by microwaves.

[0080] Furthermore, in the height direction of the atomizing cavity 104, the ratio of the dimensions of the first metal layer to the dimensions of the aerosol generating substrate 300 is 1 / 3 or less.

[0081] Based on the first to fourth embodiments, a protrusion (not shown) is further provided on the inner wall of the atomizing cavity 104. The protrusion is provided on the inner wall of the atomizing cavity 104 and can come into contact with the aerosol generating substrate 300 during operation. In this way, during the process of generating aerosols, there is a certain gap between the aerosol generating substrate 300 and the inner wall of the atomizing cavity 104, and the aerosol generated in the atomizing cavity 104 can be easily discharged smoothly from the atomizing cavity 104 through the gap.

[0082] Based on the first to fourth embodiments, and further as shown in Figures 2 and 3, the microwave introduction structure 106 is drilled into the bottom wall 112 of the atomization cavity 104. The input end of the microwave introduction structure 106 is located outside the atomization cavity 104, and the output end of the microwave introduction structure 106 is located inside the atomization cavity 104. In this way, during use, the microwave introduction structure 106 can introduce external microwaves into the atomization cavity 104 and heat the aerosol generating substrate 300 inside the atomization cavity 104. Specifically, the microwave introduction structure 106 is drilled at the center of the bottom wall 112 of the atomization cavity 104.

[0083] Based on the first to fourth embodiments, and further as shown in Figures 2 and 3, the microwave introduction structure 106 is an integral structure with the mounting base 102. In this way, there is no need to connect the microwave introduction structure 106 and the mounting base 102 using connecting members, while ensuring the connection strength between the microwave introduction structure 106 and the mounting base 102, and further improving the service life of the aerosol fixing device 100.

[0084] Specifically, the microwave introduction structure 106 and the mounting base 102 are tightly connected without any gaps.

[0085] Based on the first to fourth embodiments, as shown in Figure 3, in the height direction of the atomizing cavity 104, the dimensions of some of the microwave introduction structures 106 located within the atomizing cavity 104 are smaller than the dimensions of the aerosol generation substrate 300.

[0086] Thus, during use, after the aerosol generating substrate 300 is inserted into the atomizing cavity 104, the output terminal of the microwave introduction structure 106 is inserted into the interior of the aerosol generating substrate 300, and it is ensured that the output terminal of the microwave introduction structure 106 is not exposed from the aerosol generating substrate 300. In this way, the output terminal of the microwave introduction structure 106 can heat the interior of the aerosol generating substrate 300.

[0087] Furthermore, as shown in Figure 3, the output terminal of the microwave introduction structure 106 is located inside the aerosol generating substrate 300 to heat the internal area of ​​the aerosol generating substrate 300, while the conductor member 108 is located outside the aerosol generating substrate 300 and also on the periphery of the aerosol generating substrate 300 to heat the periphery of the aerosol generating substrate 300. In this way, the cooperation of the microwave introduction structure 106 and the conductor member 108 enables overall heating of the aerosol generating substrate 300, ensuring heating efficiency and heating uniformity for the aerosol generating substrate 300.

[0088] Specifically, the dimensions of some of the microwave introduction structures 106 located within the atomization cavity 104 may be 5 mm to 25 mm, and preferably 12 mm to 13 mm.

[0089] Furthermore, the microwave introduction structure 106 may be a metal structure or another highly conductive structure, preferably a metal structure (e.g., copper, aluminum, stainless steel, etc.). The outer surface of the non-metallic structure may be plated with a thin metal film layer (e.g., gold plating, silver plating, copper plating, etc.).

[0090] Based on the first to fourth embodiments, the mounting base 102 is further a non-conductive mounting base 102. Specifically, the material of the mounting base 102 is a low dielectric loss non-conductive material such as PEEK material, PTFE, microwave transparent ceramics, glass, silicon carbide, or alumina.

[0091] Based on the first to fourth embodiments, the microwave introduction structure 106 is a probe or a conductive sheet, as shown in Figures 2 and 3. The microwave introduction structure 106 may be a metal introduction structure (copper, aluminum, stainless steel, etc.), or a non-metallic introduction structure may be used, with a fourth metal layer (e.g., gold plating, silver plating, copper plating, etc.) provided on the outer surface of the non-metallic introduction structure.

[0092] Based on the first to fourth embodiments, and as shown in Figures 2 and 3, the atomizing cavity 104 is a cylindrical cavity 214, and the inner diameter of the atomizing cavity 104 is equal to or slightly larger than the diameter of the aerosol generating substrate 300. Specifically, the diameter of the atomizing cavity 104 may be 5 mm to 20 mm, and preferably 6.5 mm to 7.5 mm.

[0093] Based on the first to fourth embodiments, the conductive member 108 may also be manufactured using a metallic material (e.g., copper, aluminum, stainless steel, etc.) or other highly conductive material.

[0094] During use, the aerosol generating substrate 300 is installed inside the mounting rod 400.

[0095] Furthermore, as shown in Figures 6 and 7, the present invention may configure the aerosol fixing device 100 and the aerosol generating substrate 300 as an integrated structure, and the entire structure may be a sealing member. In this way, cleaning-free operation can be achieved, and the aerosol generating substrate 300 only needs to be replaced with a new one each time it is completely used. In this case, the mounting rod 400 to which the aerosol generating substrate 300 is attached is provided with a vent 402 to ensure the outflow of the generated aerosol.

[0096] As shown in Figures 1 and 8, the fifth embodiment of the present application provides an aerosol generator 200 including the aerosol fixing device 100 in any of the above embodiments. Therefore, since the aerosol generator 200 has all the effects and advantages of the aerosol fixing device 100, it will not be described in detail here.

[0097] Furthermore, as shown in Figures 1 and 8, the aerosol generator 200 further includes a housing 202, a microwave assembly, and a resonant column 206. As shown in Figures 1, 2, and 3, a resonant cavity 204 is provided within the housing 202, the microwave assembly is provided within the housing 202 and can supply microwaves into the resonant cavity 204 when in operation, and the resonant column 206 is provided within the resonant cavity 204 with its first end connected to the cavity bottom wall of the resonant cavity 204. After the aerosol fixing device 100 is installed, at least a portion of the aerosol fixing device 100 is located within the resonant cavity 204, and the input end of the microwave introduction structure 106 is connected to the second end of the resonant column 206. In this way, heating of the aerosol generating substrate 300 in the atomizing cavity 104 by microwaves supplied into the resonant cavity 204 can be ensured.

[0098] A sixth embodiment of the present invention provides an aerosol generator 200, which, based on the fifth embodiment, further includes a mounting groove 208, as shown in Figures 2, 4, and 5. The mounting groove 208 is provided at the second end of the resonant column 206 and is provided in accordance with the resonant column 206. When mounting the aerosol fixing device 100, the positioning of the aerosol fixing device 100 is ensured by positioning at least a portion of the aerosol fixing device 100 within the resonant cavity 204 and inserting the introduction end of the microwave introduction structure 106 into the mounting groove 208, while ensuring the electrical connection between the microwave introduction structure 106 and the resonant column 206.

[0099] Specifically, the conductor member 108 protruding from the bottom of the mounting base 102 can be inserted into and removed from the mounting groove 208 multiple times, and the mounting groove 208 is in close contact with and locked to the conductor member 108, thereby achieving an electrical connection.

[0100] In this embodiment, as further shown in Figures 2, 4, and 5, the dimensions of a portion of the mounting base 102 located within the resonant cavity 204 in the height direction of the aerosol generator 200 are greater than or equal to the dimensions of the aerosol generating substrate 300. In this way, it is possible to ensure that the aerosol generating substrate 300 is completely located inside the mounting base 102 during use, and that the aerosol generating substrate 300 is completely located inside the resonant cavity 204.

[0101] Specifically, the dimensions of some of the mounting bases 102 within the resonant cavity 204 may be 5mm to 25mm, and preferably 12mm to 13mm.

[0102] Based on the fifth and sixth embodiments, and further as shown in Figures 1, 3, and 8, the microwave assembly includes a microwave supply structure 210 and a microwave radiation source (not shown). The microwave supply structure 210 is provided in the housing 202, with its output end facing the bottom wall or resonant column 206 of the resonant cavity 204 and its input end connected to the microwave radiation source. Thus, when the aerosol generator 200 is operating, microwaves generated by the microwave radiation source are supplied into the resonant cavity 204 via the microwave supply structure 210.

[0103] Specifically, the resonant column 206 can function as a conductor and may be made of a metallic material; for example, the resonant column 206 may be made of copper, aluminum, iron, or an alloy thereof. The resonant column 206 transmits microwaves and improves the transmission speed of microwaves, thereby reducing attenuation as the microwaves conduct within the resonant cavity 204.

[0104] Based on the fifth and sixth embodiments, the housing 202 may also be a metal housing. Alternatively, the housing 202 may be a non-metallic housing with a second metal layer on its inner wall.

[0105] Specifically, the inner wall of the resonant cavity 204 is conductive, and the housing 202 may be made of a conductive material, preferably a metal (e.g., copper, aluminum, stainless steel, etc.), and a conductive coating (e.g., gold plating, silver plating, copper plating, etc.) may be provided on the inner wall of the housing 202.

[0106] Specifically, as shown in Figures 1, 2, and 3, the housing 202 includes a cylindrical cavity 214 and a cover 212. The inner wall of the cavity 214 is conductive, and the cover 212 is made of a plastic product with high mechanical strength, such as polycarbonate (PC) or polylactic acid (PLA).

[0107] Based on the fifth and sixth embodiments, the resonant column 206 may also be a conductive column. Alternatively, the resonant column 206 may be a non-conducting column, and the outer wall of the resonant column 206 may have a third metal layer.

[0108] Specifically, the conductor column has a hollow or solid structure, and its outer wall is conductive. The conductor column may be made of a metallic material or other highly conductive material, preferably a metal (e.g., copper, aluminum, stainless steel, etc.), or the outer surface of a non-metallic material may be plated with a thin metallic film layer (e.g., gold plating, silver plating, copper plating, etc.).

[0109] Based on the fifth and sixth embodiments, the resonant column 206 is further electrically connected to the housing 202.

[0110] Therefore, in this invention, a conductive member 108 is provided around the side wall 110 of the atomizing cavity 104. The conductive member 108 is not electrically connected to the resonant column 206, and by changing the distribution of the microwave electromagnetic field with the conductive member 108, the aerosol generating substrate 300 can be heated uniformly throughout. Furthermore, after inserting the aerosol fixing device 100 into the tip of the resonant column 206 and applying power, a strong electromagnetic field exists near the tip of the microwave introduction structure 106, so the middle and upper sections of the aerosol generating substrate 300 are rapidly heated and atomized. In addition, since the microwave introduction structure 106 and the mounting base 102 are tightly connected without any gaps, the aerosol generated when the aerosol generating substrate 300 is heated does not contaminate the internal structure of the resonant cavity 204, and cleaning is easy as only the internal structure of the aerosol fixing device 100 needs to be wiped. Furthermore, since the microwave introduction structure 106 and the mounting base 102 are integrated, if the microwave introduction structure 106 is unintentionally damaged, only the mounting base 102 needs to be replaced, which does not affect the normal heating effect of the aerosol generator 200 on the aerosol generating substrate 300, is easy to operate, is cost-effective, is advantageous for maintenance of the resonant cavity 204, and extends the service life of the aerosol generator 200.
