Description

[Technical Field]

[0001] <Explanation of divisional applications> This application claims priority to a patent application bearing application number "Patent Application No. 2024-523270" and entitled "Aerosol Generating Apparatus, Control Method and Control Device Therefor, and Readable Recording Medium," the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of aerosols, and more particularly to an aerosol generating device, a control method and device therefor, and a readable recording medium. [Background technology]

[0003] In the prior art, aerosol generating devices supply microwaves from a resonant cavity, but the microwaves are usually applied locally to the object to be atomized (e.g., the aerosol generating substrate), which results in technical problems such as the object not being heated uniformly and poor atomization efficiency. Summary of the Invention [Problem to be solved by the invention]

[0004] The present application aims to solve at least one of the technical problems encountered in the prior art. [Means for solving the problem]

[0005] Thus, in a first aspect of the present application, an aerosol generating device is provided.

[0006] In a second aspect of the present application, a method for controlling an aerosol generating device is provided.

[0007] In a third aspect of the present application, there is provided a control device for an aerosol generating device.

[0008] In a fourth aspect of the present application, a readable recording medium is provided.

[0009] In a first aspect of the present application, there is provided an aerosol generating device including a housing defining a resonant cavity, a first resonant post provided within the resonant cavity and positioned at the ceiling of the resonant cavity, the first resonant post having a hollow interior for accommodating an aerosol-generating substrate, a second resonant post provided within the resonant cavity and positioned at the bottom of the resonant cavity, and a microwave assembly provided in the housing, the microwave assembly including a first microwave introducing portion and a second microwave introducing portion, the first microwave introducing portion being used to supply microwaves to the ceiling of the resonant cavity and the second microwave introducing portion being used to supply microwaves to the bottom of the resonant cavity.

[0010] The aerosol generating device provided herein includes a housing, a first resonant column, a second resonant column, and a microwave assembly. A resonant cavity is provided within the housing, and the interior of the resonant cavity is electrically conductive. The first and second resonant columns are both provided within the resonant cavity, and are used to transmit microwaves and adjust the resonant frequency. The first and second resonant columns are in contact with the inner wall of the resonant cavity to conduct electricity. The outer walls of the first and second resonant columns are electrically conductive. The first resonant column is located at the ceiling of the resonant cavity, and the second resonant column is located at the bottom of the resonant cavity. The hollow interior of the first resonant column allows an aerosol-generating substrate to be mounted within the first resonant column, ensuring that at least a portion of the aerosol-generating substrate is positioned within the resonant cavity. The second resonant column may be solid or hollow.

[0011] The microwave assembly further includes a first microwave introduction section and a second microwave introduction section. The first microwave introduction section is provided on the ceiling of the housing and is coupled to the first resonant column, and the second microwave introduction section is provided on the bottom of the housing and is coupled to the second resonant column. During operation of the aerosol generation device, the first microwave introduction section introduces microwaves generated by the microwave assembly to the ceiling of the resonant cavity, and the second microwave introduction section introduces microwaves generated by the microwave assembly to the bottom of the resonant cavity.

[0012] In this way, microwaves introduced into the resonant cavity by the first microwave introducing section can heat a first location on the aerosol-generating substrate, and microwaves introduced into the resonant cavity by the second microwave introducing section can heat a second location on the aerosol-generating substrate. The first location is higher than the second location. That is, when the aerosol-generating device provided herein is used, at least two locations on the aerosol-generating substrate can be heated, and the top and bottom of the aerosol-generating substrate can be heated simultaneously. This significantly improves the heating efficiency of the aerosol-generating substrate, accelerating aerosol generation and improving the operating efficiency of the aerosol-generating device.

[0013] The first and second resonant posts may be conductive and may be made of a metal material, e.g., copper, aluminum, iron, or alloys thereof, and are used to transmit microwaves and improve the microwave transmission speed, so that microwaves are less attenuated when transmitted through the resonant cavity.

[0014] The first and second resonant columns can guide the microwaves to be transmitted to the aerosol-generating substrate so that the microwaves are applied to the aerosol-generating substrate, and the aerosol-generating substrate absorbs the microwaves, causing polar molecules in the aerosol-generating substrate to oscillate and convert into thermal energy, thereby heating the aerosol-generating substrate. At the same time, a part of the aerosol-generating substrate enters the resonant cavity, preventing the microwaves from being transmitted outside the housing and causing leakage, which may cause damage to the user.

[0015] In one possible design, the first resonant post includes a first opening and a second opening, the second opening communicates with the resonant cavity, and a first spacing exists between the second opening and a top of the second resonant post, such that at least a portion of the aerosol-generating substrate can enter the first resonant post through the first opening and the resonant cavity through the second opening.

[0016] In this design, the first resonant column includes a first opening and a second opening. The first opening at the top of the first resonant column is used by a user to insert an aerosol-generating substrate into the first resonant column. The second opening at the bottom of the first resonant column communicates with the resonant cavity, and a first gap exists between the second opening and the top of the second resonant column located at the bottom of the resonant cavity. In this way, at least a portion of the aerosol-generating substrate disposed inside the first resonant column can enter the resonant cavity through the first opening. Thus, during operation of the aerosol generating device, microwaves provided by the microwave assembly are applied to the aerosol-generating substrate, whereby polar molecules in the aerosol-generating substrate are rapidly oscillated and converted into thermal energy, thereby heating the aerosol generating device.

[0017] In one possible design, the microwave assembly further includes a microwave source connecting the first microwave lead and the second microwave lead.

[0018] In this design, the microwave assembly further includes a microwave source, which connects the first microwave introduction part and the second microwave introduction part, so that microwaves generated by the microwave source are introduced into the resonant cavity via the first microwave introduction part and the second microwave introduction part, respectively.

[0019] In one possible design, the microwave source includes a first microwave source connected to the first microwave lead-in and a second microwave source connected to the second microwave lead-in.

[0020] In this design, the microwave source includes a first microwave source and a second microwave source, the first microwave source is connected to the first microwave lead-in, and microwaves generated by the first microwave source can be introduced to the ceiling of the resonant cavity through the first microwave lead-in, and the second microwave source is connected to the second microwave lead-in, and microwaves generated by the second microwave source can be introduced to the bottom of the resonant cavity through the second microwave lead-in.

[0021] In this way, by generating microwaves from the first microwave emission source and the second microwave emission source, which are independent of each other, the user can heat the aerosol-generating substrate as needed. Specifically, the top of the aerosol-generating substrate can be heated by the first microwave emission source and the first microwave introduction part, and the bottom of the aerosol-generating substrate can be heated by the second microwave emission source and the second microwave introduction part. Therefore, the top and bottom of the aerosol-generating substrate can be heated by the first microwave emission source and the first microwave introduction part, and the second microwave emission source and the second microwave introduction part.

[0022] In one possible design, the first microwave introduction is provided on a side wall of the resonant cavity and / or the second microwave introduction is provided on a side wall of the resonant cavity.

[0023] In this design, the first microwave introduction part is provided on the side wall of the resonant cavity, so that the microwaves generated by the microwave assembly are introduced into the resonant cavity from the side of the resonant cavity, and correspondingly, the second microwave introduction part is provided on the side wall of the resonant cavity, so that the microwaves generated by the microwave assembly are introduced into the resonant cavity from the side of the resonant cavity. Furthermore, the first microwave introduction part and the second microwave introduction part are provided on the side wall of the resonant cavity so that the positions of the first microwave introduction part and the second microwave introduction part are reasonably distributed, so that the overall length of the aerosol generation device can be reduced.

[0024] In one possible design, the introduction end of the first microwave introduction section faces the first resonant column and / or the introduction end of the second microwave introduction section faces the second resonant column.

[0025] In this design, the introduction end of the first microwave introduction portion faces the first resonant column and is in direct electrical communication with the first resonant column. In this way, a portion of microwaves generated by the microwave assembly can be introduced directly into the first resonant column via the first microwave introduction portion. Correspondingly, the introduction end of the second microwave introduction portion faces the second resonant column and is in direct electrical communication with the second resonant column. In this way, a portion of microwaves generated by the microwave assembly can be introduced directly into the second resonant column via the second microwave introduction portion.

[0026] In this way, the microwaves introduced through the first microwave introduction section and the second microwave introduction section act directly on the first resonant column and the second resonant column, thereby reducing the length of the first microwave introduction section and the second microwave introduction section and allowing the microwaves to be quickly conducted to the first resonant column and the second resonant column, thereby avoiding microwave loss.

[0027] In one possible design, the introduction end of the first microwave introduction section faces the top wall of the resonant cavity and / or the introduction end of the second microwave introduction section faces the bottom wall of the resonant cavity.

[0028] In this design, the first microwave introduction section has an L-shape, and the introduction end of the first microwave introduction section faces the top wall of the resonant cavity and is in direct electrical communication with the top wall of the resonant cavity. In this way, a portion of the microwaves generated by the microwave assembly can be introduced directly into the top wall of the resonant cavity through the first microwave introduction section. Correspondingly, the second microwave introduction section has an L-shape, and the introduction end of the second microwave introduction section faces the bottom wall of the resonant cavity. In this way, a portion of the microwaves generated by the microwave assembly can be introduced directly into the bottom wall of the resonant cavity through the second microwave introduction section.

[0029] In one possible design, the top wall of the resonant cavity is provided with a first recess, and the introduction end of the first microwave introduction section is located within the first recess, and / or the bottom wall of the resonant cavity is provided with a second recess, and the introduction end of the second microwave introduction section is located within the second recess.

[0030] In this design, a first recess is provided on the top wall of the resonant cavity, and the introduction end of the first microwave introduction part is located within the first recess. In this way, the first recess serves to protect the introduction end of the first microwave introduction part and prevent the introduction end of the first microwave introduction part from contacting other components, thereby improving the structural stability of the microwave atomization heating device.

[0031] In this design, a second recess is provided on the bottom wall of the resonant cavity, and the introduction end of the second microwave introduction part is located within the second recess. In this way, the second recess serves to protect the introduction end of the second microwave introduction part and prevent the introduction end of the second microwave introduction part from contacting other components, thereby improving the structural stability of the microwave atomization heating device.

[0032] In one possible design, the midline of the first resonant post overlaps with the midline of the resonant cavity, and the midline of the second resonant post overlaps with the midline of the resonant cavity.

[0033] In this design, both the first resonant column and the resonant cavity have regular shapes. For example, both the first resonant column and the resonant cavity are cylindrical, and the midline of the first resonant column overlaps with the midline of the resonant cavity. That is, the axis of the first resonant column overlaps with the axis of the resonant cavity. By overlapping the centers of the first resonant column and the resonant cavity, the centers of the first resonant column and the aerosol-generating substrate also overlap. This allows the microwaves transmitted by the first resonant column to be further applied to the aerosol-generating substrate. The microwaves are concentrated and applied to the aerosol-generating substrate, which can heat the aerosol-generating substrate in a short time, thereby achieving instant heating.

[0034] In this design, the second resonant column and the resonant cavity are both regular shapes. For example, the second resonant column and the resonant cavity are both cylindrical, with the midline of the second resonant column overlapping with the midline of the resonant cavity. That is, the axis of the second resonant column overlaps with the axis of the resonant cavity. By overlapping the centers of the second resonant column and the resonant cavity, the centers of the second resonant column and the aerosol-generating substrate also overlap. As a result, the microwaves transmitted by the second resonant column can be further applied to the aerosol-generating substrate. The microwaves are concentrated and applied to the aerosol-generating substrate, which can heat the aerosol-generating substrate in a short time, thereby achieving instant heating.

[0035] In one possible design, a first resonant post is connected to the top wall of the resonant cavity and / or a second resonant post is connected to the bottom wall of the resonant cavity.

[0036] In this design, the first resonant column is connected to the top wall of the resonant cavity, which not only ensures a stable connection of the first resonant column but also ensures that the first resonant column can directly conduct microwaves from the ceiling of the resonant cavity, thereby improving the microwave conduction effect.

[0037] In this design, the second resonant post is connected to the bottom wall of the resonant cavity, which not only ensures stable connection of the second resonant post but also ensures that the second resonant post can directly conduct microwaves from the bottom wall of the resonant cavity, thereby improving the microwave conduction effect.

[0038] In one possible design, there is a second spacing between the first resonant post and the inner wall of the resonant cavity, and there is a third spacing between the second resonant post and the inner wall of the resonant cavity.

[0039] In this design, a second distance is provided between the first resonant post and the inner wall of the resonant cavity to ensure a certain space between the first resonant post and the interior of the resonant cavity, and a third distance is provided between the second resonant post and the inner wall of the resonant cavity to ensure a certain space between the second resonant post and the interior of the resonant cavity.

[0040] In one possible design, the resonant cavity is a cylindrical cavity.

[0041] In this design, the resonant cavity is a cylindrical cavity. The first and second resonant cylinders are both cylindrical structures. The midline of the first resonant cylinder overlaps with the midline of the resonant cavity, and the midline of the second resonant cylinder overlaps with the midline of the resonant cavity. This ensures that microwaves uniformly heat the surroundings of the aerosol-generating substrate during microwave propagation, thereby improving the heating effect on the aerosol-generating substrate.

[0042] In one possible design, the housing is a metal housing.

[0043] In this design, the housing is a metal housing, for example, made of copper, aluminum, iron, etc., or alloys thereof.

[0044] In a second aspect of the present application, there is provided a control method for an aerosol generating device used in any of the above-described designs, the control method including controlling at least one of the first microwave introducing part and the second microwave introducing part to supply microwaves into a resonant cavity in response to an atomization command.

[0045] The control method for an aerosol generating device provided by the present application is used in any of the aerosol generating devices according to the above designs. Specifically, during operation, at least one of the first microwave introducing unit and the second microwave introducing unit is controlled to supply microwaves into the resonant cavity in response to an atomization command. The microwaves introduced into the resonant cavity by the first microwave introducing unit can heat a first location on the aerosol-generating substrate, and the microwaves introduced into the resonant cavity by the second microwave introducing unit can heat a second location on the aerosol-generating substrate. Note that the first location is higher than the second location.

[0046] Therefore, the control method for an aerosol-generating device provided by the present application allows the aerosol-generating substrate to be heated according to a user's selection. Specifically, the top of the aerosol-generating substrate can be heated by the first microwave introduction unit, the bottom of the aerosol-generating substrate can be heated by the second microwave introduction unit, and the top and bottom of the aerosol-generating substrate can be heated by the first microwave introduction unit, the second microwave emission source, and the second microwave introduction unit.

[0047] Therefore, according to the present invention, at least two locations of the aerosol-generating substrate can be heated, and the top and bottom portions of the aerosol-generating substrate can be heated simultaneously, thereby significantly improving the heating efficiency of the aerosol-generating substrate, thereby accelerating the generation of aerosol and improving the operating efficiency of the aerosol-generating device.

[0048] In one possible design, the control method of the aerosol generating device specifically includes controlling the first microwave introducing part and the second microwave introducing part to simultaneously supply microwaves into the resonant cavity in response to an atomization command.

[0049] In this design, when heating the aerosol-generating substrate, the first microwave introducing unit and the second microwave introducing unit are controlled to simultaneously supply microwaves into the resonant cavity in response to an atomization command. In this way, the microwaves introduced into the resonant cavity by the first microwave introducing unit can heat a first location on the aerosol-generating substrate, and simultaneously, the microwaves introduced into the resonant cavity by the second microwave introducing unit can heat a second location on the aerosol-generating substrate.

[0050] That is, in this design, the top and bottom of the aerosol-generating substrate can be heated simultaneously, thus significantly improving the heating efficiency of the aerosol-generating substrate, thereby accelerating the generation of aerosol and improving the operating efficiency of the aerosol-generating device.

[0051] In one possible design, the control method for the aerosol-generating device specifically includes: controlling a first microwave introducing unit to supply microwaves into a resonant cavity in response to an atomization command, thereby heating a first location on the aerosol-generating substrate to a first temperature; and, after the first microwave introducing unit operates for a predetermined time, controlling a second microwave introducing unit to supply microwaves into the resonant cavity, thereby heating a second location on the aerosol-generating substrate to a second temperature that is equal to or higher than the first temperature.

[0052] In this design, when heating the aerosol-generating substrate, in response to an atomization command, first, the first microwave introducing unit is controlled to supply microwaves into the resonant cavity, thereby heating a first location on the aerosol-generating substrate to a first temperature; then, after the first microwave introducing unit has been operated for a predetermined time, the second microwave introducing unit is controlled to supply microwaves into the resonant cavity, thereby heating a second location on the aerosol-generating substrate to a second temperature higher than the first temperature.

[0053] That is, in this design, microwaves are first supplied to the ceiling of the resonant cavity by the first microwave introducing part, while microwaves are not supplied to the bottom of the resonant cavity. At this time, the upper half of the aerosol-generating substrate is heated so that its temperature reaches a first temperature. After the upper half of the aerosol-generating substrate has been heated to a certain degree, microwaves are supplied to the bottom of the resonant cavity by the microwave introducing part, and at this time, the lower half of the aerosol-generating substrate is heated so that its temperature reaches a second temperature.

[0054] In one possible design, a second microwave introduction section is controlled to supply microwaves into the resonant cavity while a first microwave introduction section is controlled to supply microwaves into the resonant cavity, heating a first location of the aerosol-generating substrate to a third temperature that is lower than the first temperature.

[0055] In this design, a second microwave introduction section is controlled to supply microwaves into the resonant cavity, while at the same time the microwave introduction section supplies microwaves to the ceiling of the resonant cavity, heating a first location of the aerosol-generating substrate to a third temperature that is lower than the first temperature.

[0056] In one possible design, the second microwave introduction section is controlled to supply microwaves into the resonant cavity while the first microwave introduction section is controlled to be inactive.

[0057] In this design, the second microwave introduction unit can be controlled to supply microwaves into the resonant cavity while the first microwave introduction unit is controlled to be deactivated, so that only the second microwave introduction unit supplies microwaves into the resonant cavity.

[0058] In a third aspect of the present application, there is provided a control device for an aerosol generation device used in any of the above-described aerosol generation devices, which includes a control unit that controls at least one of the first microwave introduction part and the second microwave introduction part to supply microwaves into the resonant cavity in response to an atomization command.

[0059] The control device for an aerosol generating device provided by the present application is used in the aerosol generating device according to any of the above designs. Specifically, the control device for an aerosol generating device includes a control unit.

[0060] In operation, in response to an atomization command, the control unit controls at least one of the first microwave introduction section and the second microwave introduction section to supply microwaves into the resonant cavity. The microwaves introduced into the resonant cavity by the first microwave introduction section can heat a first location on the aerosol-generating substrate, and the microwaves introduced into the resonant cavity by the second microwave introduction section can heat a second location on the aerosol-generating substrate, the first location being higher than the second location.

[0061] Therefore, the control device of the aerosol-generating device provided herein can heat the aerosol-generating substrate according to a user's selection. Specifically, the top of the aerosol-generating substrate can be heated by the first microwave introduction unit, the bottom of the aerosol-generating substrate can be heated by the second microwave introduction unit, and the top and bottom of the aerosol-generating substrate can be heated by the first microwave introduction unit, the second microwave source, and the second microwave introduction unit.

[0062] Therefore, according to the present invention, at least two locations of the aerosol-generating substrate can be heated, or the top and bottom of the aerosol-generating substrate can be heated simultaneously, thereby significantly improving the heating efficiency of the aerosol-generating substrate, thereby accelerating the generation of aerosol and improving the operating efficiency of the aerosol-generating device.

[0063] In a fourth aspect of the present application, a readable recording medium is provided, which stores a program or instructions, and when the program or instructions are executed by a processor, implements a control method for an aerosol generating device according to any of the above designs.

[0064] The readable recording medium provided in the fourth aspect of the present application can implement the control method for the aerosol generating device according to any of the above designs when the stored program is executed, and thus has all the beneficial effects of the control method for the aerosol generating device, which will not be described in detail here.

DETAILED DESCRIPTION OF THE INVENTION

[0067] In order to clarify the above-mentioned objects, features, and advantages of the present application, specific embodiments of the present application will be described in detail below with reference to the drawings. Unless inconsistent, the embodiments of the present application and the features disclosed in the embodiments can be combined.

[0068] In the following description, specific details are described to ensure a thorough understanding of the present application, but the present application may be implemented in embodiments different from those described in this specification, and therefore the present application is not limited to the following specific examples.

[0069] Hereinafter, an aerosol generating device, a control method and control device therefor, and a readable recording medium provided according to some embodiments of the present application will be described with reference to Figures 1 to 12. The second microwave introduction section 114 is not shown in Figures 1 and 2. Line segment L1 in Figure 10 shows the relationship between the heating time and the heating temperature of the first location 202, and line segment L2 in Figure 10 shows the relationship between the heating time and the heating temperature of the second location 204.

[0070] As shown in FIGS. 1 and 2, in a first embodiment of the present application, an aerosol generating device is provided, which includes a housing 102, a first resonant post 106, a second resonant post 108, and a microwave assembly 110.

[0071] As shown in FIGS. 3 and 4 , a resonant cavity 104 is provided inside the housing 102. The interior of the resonant cavity 104 is electrically conductive. A first resonant column 106 and a second resonant column 108 are both provided inside the resonant cavity 104. The first resonant column 106 and the second resonant column 108 are used to transmit microwaves and adjust the resonant frequency. The first resonant column 106 and the second resonant column 108 are in contact with the inner wall of the resonant cavity 104 and conduct electricity. The outer walls of the first resonant column 106 and the second resonant column 108 are electrically conductive. The first resonant column 106 is located at the ceiling of the resonant cavity 104, and the second resonant column 108 is located at the bottom of the resonant cavity 104.

[0072] 3 and 4, the first resonant column 106 has a hollow interior, which ensures that the aerosol-generating substrate 200 is mounted inside the first resonant column 106 and that at least a portion of the aerosol-generating substrate 200 is located within the resonant cavity 104. The second resonant column 108 may be solid or hollow.

[0073] 3 and 4, the microwave assembly 110 includes a first microwave introduction portion 112 and a second microwave introduction portion 114. The first microwave introduction portion 112 is provided on the ceiling of the housing 102 and is connected to the first resonant column 106, and the second microwave introduction portion 114 is provided on the bottom of the housing 102 and is connected to the second resonant column 108. During operation of the aerosol generation device, the first microwave introduction portion 112 introduces microwaves generated by the microwave assembly 110 into the ceiling of the resonant cavity 104, and the second microwave introduction portion 114 introduces microwaves generated by the microwave assembly 110 into the bottom of the resonant cavity 104.

[0074] 5, 6, 7 and 8, the microwaves introduced into the resonant cavity 104 by the first microwave introducing part 112 can heat a first location 202 of the aerosol-generating substrate 200, and the microwaves introduced into the resonant cavity 104 by the second microwave introducing part 114 can heat a second location 204 of the aerosol-generating substrate 200. Note that the first location 202 is higher than the second location 204.

[0075] That is, when the aerosol-generating device provided by the present application is used, it is possible to heat at least two locations on the aerosol-generating substrate 200, and simultaneously heat the top and bottom of the aerosol-generating substrate 200. In this way, the heating efficiency of the aerosol-generating substrate 200 can be significantly improved, thereby accelerating the generation of the aerosol 300 and improving the operating efficiency of the aerosol-generating device.

[0076] The first resonant post 106 and the second resonant post 108 may be conductive and may be made of a metal material, for example, copper, aluminum, iron, or an alloy thereof. The first resonant post 106 and the second resonant post 108 are used to transmit microwaves and improve the microwave transmission speed, so that the microwaves are less attenuated when they are transmitted within the resonant cavity 104.

[0077] In addition, the first resonant column 106 and the second resonant column 108 can guide the microwaves transmitted to the aerosol-generating substrate 200 so that the microwaves are applied to the aerosol-generating substrate 200. As a result, the aerosol-generating substrate 200 absorbs the microwaves, and the polar molecules in the aerosol-generating substrate 200 rapidly oscillate and convert into thermal energy, thereby heating the aerosol-generating substrate 200. At the same time, a part of the aerosol-generating substrate 200 enters the resonant cavity 104, which prevents the microwaves from being transmitted to the housing 102 and causing leakage, which may cause damage to the user.

[0078] A second embodiment of the present application provides an aerosol generating device, which, in addition to the features of the first embodiment, further comprises: 2, 5, 6, 7, and 8, the first resonant post 106 includes a first opening and a second opening. The first opening at the top of the first resonant post 106 is used by a user to insert an aerosol-generating substrate 200 into the first resonant post 106, and the second opening at the bottom of the first resonant post 106 communicates with the resonant cavity 104. A first distance exists between the second opening and the top of the second resonant post 108 located at the bottom of the resonant cavity 104.

[0079] In this manner, at least a portion of the aerosol-generating substrate 200 disposed inside the first resonant column 106 enters the inside of the resonant cavity 104 through the first opening. Thus, when the aerosol-generating device is in operation, microwaves provided by the microwave assembly 110 are applied to the aerosol-generating substrate 200, causing polar molecules in the aerosol-generating substrate 200 to rapidly oscillate and be converted into thermal energy, thereby heating the aerosol-generating substrate 200.

[0080] 9 , the aerosol-generating substrate 200 includes a first location 202 at the top and a second location 204 at the bottom. When in use, the aerosol-generating substrate 200 needs to be mounted inside the mounting structure 400. That is, when the aerosol-generating device is to be operated, the user inserts the mounting structure 400, on which the aerosol-generating substrate 200 is mounted, into the first resonant column 106, thereby placing the aerosol-generating substrate 200 inside the resonant cavity 104 and between the first resonant column 106 and the second resonant column 108. In this manner, microwaves transmitted by the first resonant column 106 are directly applied to the first location 202 at the top of the aerosol-generating substrate 200, and microwaves transmitted by the second resonant column 108 are directly applied to the second location 204 at the top of the aerosol-generating substrate 200.

[0081] A third embodiment of the present application provides an aerosol generating device, which, in addition to the configuration of the first embodiment, further comprises a microwave assembly 110 including a microwave emission source (not shown). The microwave emission source connects the first microwave introduction portion 112 and the second microwave introduction portion 114, so that microwaves generated by the microwave emission source are introduced into the resonant cavity 104 via the first microwave introduction portion 112 and the second microwave introduction portion 114, respectively.

[0082] In this embodiment, the microwave emission source further includes a first microwave emission source (not shown) and a second microwave emission source (not shown). The first microwave emission source is connected to the first microwave introduction part 112, and microwaves generated by the first microwave emission source can be introduced to the ceiling of the resonant cavity 104 via the first microwave introduction part 112. The second microwave emission source is connected to the second microwave introduction part 114, and microwaves generated by the second microwave emission source can be introduced to the bottom of the resonant cavity 104 via the second microwave introduction part 114.

[0083] In this way, by generating microwaves from the first microwave emission source and the second microwave emission source, which are independent of each other, the user can heat the aerosol-generating substrate 200 as needed. Specifically, as shown in FIG. 7, the top of the aerosol-generating substrate 200 can be heated by the first microwave emission source and the first microwave introduction unit 112, so that the aerosol 300 is first generated at the first location 202. As shown in FIG. 6, the bottom of the aerosol-generating substrate 200 can be further heated by the second microwave emission source and the second microwave introduction unit 114, so that the aerosol 300 is first generated at the second location 204. As shown in FIG. 8, the top and bottom of the aerosol-generating substrate 200 can be further heated by the first microwave emission source and the first microwave introduction unit 112, and the second microwave emission source and the second microwave introduction unit 114, so that the aerosol 300 is simultaneously generated at the first location 202 and the second location 204.

[0084] A fourth embodiment of the present application provides an aerosol generating device. The aerosol generating device has the same configuration as the first embodiment, except that, as shown in FIGS. 1 and 2, a first microwave introducing portion 112 is provided on a side wall of a resonant cavity 104, thereby allowing microwaves generated by a microwave assembly 110 to be introduced into the resonant cavity 104 from the side of the resonant cavity 104. Correspondingly, a second microwave introducing portion 114 is provided on a side wall of the resonant cavity 104, thereby allowing microwaves generated by the microwave assembly 110 to be introduced into the resonant cavity 104 from the side of the resonant cavity 104. Furthermore, the first microwave introducing portion 112 and the second microwave introducing portion 114 are provided on the side wall of the resonant cavity 104 such that their positions are reasonably distributed, thereby reducing the overall length of the aerosol generating device.

[0085] A fifth embodiment of the present application provides an aerosol generating device, which, in addition to the features of the first embodiment, further comprises, as shown in Fig. 3, an introduction end of a first microwave introduction section 112 facing the first resonant column 106 and directly electrically connected to the first resonant column 106. In this way, a portion of microwaves generated by the microwave assembly 110 can be directly introduced into the first resonant column 106 via the first microwave introduction section 112.

[0086] 3, the introduction end of the second microwave introduction portion 114 faces the second resonant post 108, and is directly electrically connected to the second resonant post 108. In this way, a portion of the microwaves generated by the microwave assembly 110 can be directly introduced into the second resonant post 108 via the second microwave introduction portion 114.

[0087] In this way, the microwaves introduced through the first microwave introduction section 112 and the second microwave introduction section 114 act directly on the first resonant column 106 and the second resonant column 108, thereby reducing the lengths of the first microwave introduction section 112 and the second microwave introduction section 114 and quickly conducting the microwaves to the first resonant column 106 and the second resonant column 108, thereby avoiding microwave loss.

[0088] A sixth embodiment of the present application provides an aerosol generating device, which, in addition to the features of the first embodiment, further comprises, as shown in Fig. 4, an L-shaped first microwave introducing portion 112, an introducing end of the first microwave introducing portion 112 facing the top wall of the resonant cavity 104, and the introducing end of the first microwave introducing portion 112 directly electrically connected to the top wall of the resonant cavity 104. In this way, a portion of the microwaves generated by the microwave assembly 110 can be introduced directly to the top wall of the resonant cavity 104 via the first microwave introducing portion 112.

[0089] 4, the second microwave introducing portion 114 has an L-shape, and the introducing end of the second microwave introducing portion 114 is electrically connected directly to the bottom wall of the resonant cavity 104, and the introducing end of the second microwave introducing portion 114 faces the bottom wall of the resonant cavity 104. In this way, a part of the microwaves generated by the microwave assembly 110 can be introduced directly into the bottom wall of the resonant cavity 104 through the second microwave introducing portion 114.

[0090] 2, in this embodiment, a first recess 116 is provided in the top wall of the resonant cavity 104, and the introduction end of the first microwave introduction part 112 is located within the first recess 116. In this way, the first recess 116 serves to protect the introduction end of the first microwave introduction part 112, preventing the introduction end of the first microwave introduction part 112 from coming into contact with other components, thereby improving the structural stability of the microwave atomization heating device.

[0091] Correspondingly, a second recess (not shown) is provided in the bottom wall of resonant cavity 104, and the introduction end of second microwave introduction part 114 is located within the second recess. In this way, the second recess serves to protect the introduction end of second microwave introduction part 114 and prevents the introduction end of second microwave introduction part 114 from contacting other components, thereby improving the structural stability of the microwave atomization heating device.

[0092] Based on the first to sixth embodiments, as shown in FIG. 2 , the first resonant column 106 and the resonant cavity 104 are both regular shapes. For example, the first resonant column 106 and the resonant cavity 104 are both cylindrical, and the midline of the first resonant column 106 overlaps with the midline of the resonant cavity 104. That is, the axis of the first resonant column 106 overlaps with the axis of the resonant cavity 104. By overlapping the centers of the first resonant column 106 and the resonant cavity 104, the centers of the first resonant column 106 and the aerosol-generating substrate 200 also overlap. As a result, the microwaves transmitted by the first resonant column 106 can be further applied to the aerosol-generating substrate 200. As a result, the microwaves are concentrated and applied to the aerosol-generating substrate 200, which can heat the aerosol-generating substrate 200 in a short time, which is advantageous in that instant heating can be achieved.

[0093] Based on the first to sixth embodiments, as shown in FIG. 2 , the second resonant cylinder 108 and the resonant cavity 104 are both regular shapes. For example, the second resonant cylinder 108 and the resonant cavity 104 are both cylindrical, and the midline of the second resonant cylinder 108 overlaps with the midline of the resonant cavity 104. That is, the axis of the second resonant cylinder 108 overlaps with the axis of the resonant cavity 104. By overlapping the centers of the second resonant cylinder 108 and the resonant cavity 104, the centers of the second resonant cylinder 108 and the aerosol-generating substrate 200 also overlap. As a result, the microwaves transmitted by the second resonant cylinder 108 can be further applied to the aerosol-generating substrate 200. As a result, the microwaves are concentrated and applied to the aerosol-generating substrate 200, which can heat the aerosol-generating substrate 200 in a short time, which is advantageous in that instant heating can be achieved.

[0094] Based on the first to sixth embodiments, as shown in Fig. 2, the second resonant column 108 is connected to the bottom wall of the resonant cavity 104. In this way, it is possible to ensure stable connection of the second resonant column 108 and also to ensure that the second resonant column 108 can directly conduct microwaves from the bottom wall of the resonant cavity 104, thereby improving the microwave conduction effect.

[0095] Based on the first to sixth embodiments, as shown in FIG. 2, a second gap 118 is provided between the first resonant column 106 and the inner wall of the resonant cavity 104, ensuring that a certain space exists between the first resonant column 106 and the inside of the resonant cavity 104.

[0096] Correspondingly, as shown in FIG. 2, there is a third gap 120 between the second resonant post 108 and the inner wall of the resonant cavity 104, thereby ensuring that there is a certain space between the second resonant post 108 and the interior of the resonant cavity 104.

[0097] Based on the first to sixth embodiments, as shown in Fig. 2, the resonant cavity 104 is a cylindrical cavity. The first resonant cylinder 106 and the second resonant cylinder 108 both have cylindrical structures. In this way, the midline of the first resonant cylinder 106 overlaps with the midline of the resonant cavity 104, and the midline of the second resonant cylinder 108 overlaps with the midline of the resonant cavity 104. This ensures that the microwaves uniformly heat the surroundings of the aerosol-generating substrate 200 as they propagate, thereby improving the heating effect on the aerosol-generating substrate 200.

[0098] Based on the first to sixth embodiments, the housing 102 is a metal housing. For example, the housing 102 is made of copper, aluminum, iron, or an alloy thereof.

[0099] A seventh embodiment of the present application provides a method for controlling an aerosol generation apparatus used in the aerosol generation apparatus according to any one of the above embodiments. As shown in FIG. 11, the method for controlling an aerosol generation apparatus includes: The method includes step 1102 of controlling at least one of the first microwave introduction unit and the second microwave introduction unit to supply microwaves into the resonant cavity in response to an atomization command.

[0100] The control method for an aerosol generating device provided by the present application is used in any of the aerosol generating devices according to the above designs. Specifically, during operation, at least one of the first microwave introducing unit and the second microwave introducing unit is controlled to supply microwaves into the resonant cavity in response to an atomization command. The microwaves introduced into the resonant cavity by the first microwave introducing unit can heat a first location on the aerosol-generating substrate, and the microwaves introduced into the resonant cavity by the second microwave introducing unit can heat a second location on the aerosol-generating substrate. Note that the first location is higher than the second location.

[0101] Therefore, the control method for an aerosol-generating device provided by the present application allows the aerosol-generating substrate to be heated according to a user's selection. Specifically, the top of the aerosol-generating substrate can be heated by the first microwave introduction unit, the bottom of the aerosol-generating substrate can be heated by the second microwave introduction unit, and the top and bottom of the aerosol-generating substrate can be heated by the first microwave introduction unit, the second microwave emission source, and the second microwave introduction unit.

[0102] Therefore, according to the present invention, at least two locations of the aerosol-generating substrate can be heated, and the top and bottom portions of the aerosol-generating substrate can be heated simultaneously, thereby significantly improving the heating efficiency of the aerosol-generating substrate, thereby accelerating the generation of aerosol and improving the operating efficiency of the aerosol-generating device.

[0103] An eighth embodiment of the present application provides a method for controlling an aerosol generating device. In addition to the seventh embodiment, the method further controls the first microwave introducing unit and the second microwave introducing unit to simultaneously supply microwaves into the resonant cavity in response to an atomization command when heating the aerosol-generating substrate. In this way, the microwaves introduced into the resonant cavity by the first microwave introducing unit can heat a first location on the aerosol-generating substrate, and simultaneously, the microwaves introduced into the resonant cavity by the second microwave introducing unit can heat a second location on the aerosol-generating substrate.

[0104] In other words, in this embodiment, the top and bottom of the aerosol-generating substrate can be heated simultaneously, thereby significantly improving the heating efficiency of the aerosol-generating substrate, thereby accelerating the generation of aerosol and improving the operating efficiency of the aerosol-generating device.

[0105] A ninth embodiment of the present application provides a method for controlling an aerosol-generating apparatus. In addition to the eighth embodiment, as shown in Fig. 10, when heating an aerosol-generating substrate, the method first controls the first microwave introducing unit to supply microwaves into the resonant cavity in response to an atomization command, thereby heating a first location on the aerosol-generating substrate to a first temperature T1, and then, after the first microwave introducing unit has been operated for a preset time, controls the second microwave introducing unit to supply microwaves into the resonant cavity, thereby heating a second location on the aerosol-generating substrate to a second temperature T2 higher than the first temperature T1.

[0106] 10, in this embodiment, microwaves are first supplied to the ceiling of the resonant cavity by the first microwave introducing part, but microwaves are not supplied to the bottom of the resonant cavity. At this time, the upper half of the aerosol-generating substrate is heated so that its temperature reaches a first temperature T1. After the upper half of the aerosol-generating substrate has been heated to a certain degree, microwaves are supplied to the bottom of the resonant cavity by the microwave introducing part, and the lower half of the aerosol-generating substrate is heated so that its temperature reaches a second temperature T2.

[0107] Furthermore, as shown in Figure 10, the second microwave introducing unit is controlled to supply microwaves into the resonant cavity, and at the same time, the first microwave introducing unit is controlled to supply microwaves into the resonant cavity, thereby heating the first location of the aerosol generating substrate to a third temperature T3 that is lower than the first temperature T1.

[0108] Furthermore, the second microwave introducing unit can be controlled to supply microwaves into the resonant cavity while the first microwave introducing unit can be controlled to stop operating, so that only the second microwave introducing unit supplies microwaves into the resonant cavity.

[0109] 12 , a tenth embodiment of the present application provides an aerosol generating device control device 1200 for use in the aerosol generating device according to any one of the above embodiments. Specifically, the aerosol generating device control device 1200 includes a control unit 1202.

[0110] In operation, in response to an atomization command, the control unit 1202 controls at least one of the first microwave introduction section 112 and the second microwave introduction section 114 to supply microwaves into the resonant cavity. The microwaves introduced into the resonant cavity by the first microwave introduction section 112 can heat a first location on the aerosol-generating substrate, and the microwaves introduced into the resonant cavity by the second microwave introduction section 114 can heat a second location on the aerosol-generating substrate. The first location is higher than the second location.

[0111] Therefore, the control device 1200 of the aerosol-generating device provided herein can heat the aerosol-generating substrate according to a user's selection. Specifically, the top of the aerosol-generating substrate can be heated by the first microwave introduction unit, the bottom of the aerosol-generating substrate can be heated by the second microwave introduction unit, and the top and bottom of the aerosol-generating substrate can be heated by the first microwave introduction unit, the second microwave emission source, and the second microwave introduction unit.

[0112] Therefore, according to the present invention, at least two locations of the aerosol-generating substrate can be heated, or the top and bottom of the aerosol-generating substrate can be heated simultaneously, thereby significantly improving the heating efficiency of the aerosol-generating substrate, thereby accelerating the generation of aerosol and improving the operating efficiency of the aerosol-generating device.

[0113] An eleventh embodiment of the present application provides a control device 1200 for an aerosol generating device. In addition to the features of the tenth embodiment, the control device 1200 for an aerosol generating device further includes, as shown in Fig. 12, a control unit 1202 that specifically controls the first microwave introducing part and the second microwave introducing part to simultaneously supply microwaves into the resonant cavity in response to an atomization command.

[0114] Specifically, when heating the aerosol-generating substrate, in response to an atomization command, the control unit 1202 controls the first microwave introducing unit 112 and the second microwave introducing unit 114 to simultaneously supply microwaves into the resonant cavity. In this way, the microwaves introduced into the resonant cavity by the first microwave introducing unit 112 can heat a first location on the aerosol-generating substrate, and simultaneously, the microwaves introduced into the resonant cavity by the second microwave introducing unit 114 can heat a second location on the aerosol-generating substrate.

[0115] In other words, in this embodiment, the top and bottom of the aerosol-generating substrate can be heated simultaneously, thereby significantly improving the heating efficiency of the aerosol-generating substrate, thereby accelerating the generation of aerosol and improving the operating efficiency of the aerosol-generating device.

[0116] A twelfth embodiment of the present application provides a control device 1200 for an aerosol-generating device. In addition to the features of the tenth embodiment, the control device 1200 for the aerosol-generating device further includes, as shown in Fig. 12, a control unit 1202 that, in response to an atomization command, controls the first microwave introducing unit to supply microwaves into the resonant cavity to heat a first location on the aerosol-generating substrate to a first temperature T1, and, after the first microwave introducing unit has been operated for a preset time, controls the second microwave introducing unit to supply microwaves into the resonant cavity to heat a second location on the aerosol-generating substrate to a second temperature T2 higher than the first temperature T1.

[0117] Specifically, when heating the aerosol-generating substrate, in response to an atomization command, the control unit 1202 first controls the first microwave introducing unit to supply microwaves into the resonant cavity, thereby heating a first location on the aerosol-generating substrate to a first temperature T1; then, after the first microwave introducing unit has operated for a predetermined time, the control unit 1202 controls the second microwave introducing unit to supply microwaves into the resonant cavity, thereby heating a second location on the aerosol-generating substrate to a second temperature T2 higher than the first temperature T1.

[0118] That is, in this embodiment, microwaves are first supplied to the ceiling of the resonant cavity by the first microwave introducing part, but microwaves are not supplied to the bottom of the resonant cavity. At this time, the upper half of the aerosol-generating substrate is heated so that its temperature reaches a first temperature T1. After the upper half of the aerosol-generating substrate has been heated to a certain degree, microwaves are supplied to the bottom of the resonant cavity by the microwave introducing part, and the lower half of the aerosol-generating substrate is heated so that its temperature reaches a second temperature T2.

[0119] Furthermore, while controlling the second microwave introduction section to supply microwaves into the resonant cavity, the control unit 1202 can control the microwave introduction section to supply microwaves to the ceiling of the resonant cavity, so that the first location of the aerosol-generating substrate is heated to a third temperature T3 that is lower than the first temperature T1.

[0120] Furthermore, while controlling the second microwave introducing part to supply microwaves into the resonant cavity, the control unit 1202 can control the first microwave introducing part to stop operating, so that only the second microwave introducing part supplies microwaves into the resonant cavity.

[0121] A thirteenth embodiment of the present application provides a readable recording medium. When a program stored in the readable recording medium is executed, the method for controlling the aerosol generating device according to any one of the above embodiments can be implemented.

[0122] Therefore, the readable recording medium has all the beneficial effects of the above-mentioned method for controlling an aerosol generating device, which will not be described in detail here.

[0123] In a specific embodiment, the aerosol generating device provided herein includes a coaxial resonant cavity 104 within a housing 102. The resonant cavity 104 is cylindrical, and the interior of the resonant cavity 104 is electrically conductive and typically made of metal. A first resonant column 106 and a second resonant column 108 are located along the central axis of the resonant cavity 104, and are used to transmit microwaves and adjust the resonant frequency. The first resonant column 106 and the second resonant column 108 are electrically conductive and in contact with the interior of the resonant cavity 104. The second resonant column 108, located at the bottom, may be solid or hollow, and the exterior of the second resonant column 108 is electrically conductive. The first resonant column 106, located at the ceiling, is hollow, and the exterior of the first resonant column 106 is electrically conductive, and the interior of the first resonant column 106 is hollow, allowing the aerosol-generating substrate 200 to be placed thereon. The microwave assembly 110 includes two microwave introduction sections: the second microwave introduction section 114 is located at the bottom of the resonant cavity 104, and the first microwave introduction section 112 is located at the ceiling of the resonant cavity 104. The first microwave introduction section 112 and the second microwave introduction section 114 may be L-shaped, and their introduction ends may be electrically conductively connected to the resonant cavity 104 or directly connected to the first resonant post 106 and the second resonant post 108. The first microwave introduction section 112 and the second microwave introduction section 114 communicate with an external microwave source. In operation, the first microwave introduction section 112 and the second microwave introduction section 114 may or may not simultaneously supply microwaves.

[0124] 10 and 11, when the aerosol-generating device is operated, the first microwave introducing unit 112 located on the ceiling initially supplies microwaves, while the second microwave introducing unit 114 located on the bottom does not supply microwaves, and the first location 202 of the aerosol-generating substrate 200 is heated until the temperature of the first location 202 of the aerosol-generating substrate 200 reaches a first temperature T1. After that, after the first location 202 of the aerosol-generating substrate 200 has been heated to a certain degree, the second microwave introducing unit 114 located on the bottom supplies microwaves, and the second location 204 of the aerosol-generating substrate 200 is heated until the temperature of the first location 202 of the aerosol-generating substrate 200 reaches a second temperature T2. Furthermore, while microwaves are supplied to the second location 204 of the aerosol-generating substrate 200, the first microwave introducing section 112 arranged on the ceiling also supplies microwaves, and the aerosol-generating substrate 200 is heated to a third temperature T3 at the first location 202. Specifically, the third temperature T3 is equal to or lower than the first temperature T1, and the second temperature T2 is equal to or higher than the first temperature T1.

[0125] Specifically, when the aerosol-generating device of the present application simultaneously heats the first location 202 and the second location 204 of the aerosol-generating substrate 200, the microwave field is distributed more uniformly, allowing the aerosol-generating substrate 200 to be sufficiently heated. Alternatively, the first location 202 of the aerosol-generating substrate 200 is atomized first, followed by the second location 204 of the aerosol-generating substrate 200, which is beneficial for the stability of the texture.
