Description

Technical Field

[0001] This invention belongs to the field of atomization equipment technology, and more specifically, relates to an aerosol generating device. Background Technology

[0002] A heat-not-burning (HNB) device is an electronic device used to heat an aerosol-generating matrix (treated plant leaf products) without causing combustion. The heating device heats the aerosol-generating matrix to a temperature high enough to produce aerosols but not hot enough to burn them, allowing the matrix to generate the desired aerosols without combustion.

[0003] Currently, most heated non-combustible (HNB) appliances on the market use resistance heating, which involves inserting a central heating element or heating needle into the aerosol-generating matrix to heat it. These appliances require long preheating times, cannot be freely stopped or withdrawn, and suffer from uneven carbonization of the aerosol-generating matrix, resulting in insufficient baking and low utilization. Furthermore, the heating element in HNB appliances is prone to accumulating dirt in the aerosol-generating matrix extractor and heating element base, making cleaning difficult. This can cause excessively high temperatures in the localized areas of the aerosol-generating matrix in contact with the heating element, leading to partial decomposition and the release of harmful substances. Therefore, microwave heating technology is gradually replacing resistance heating as the new heating method. Microwave heating technology is characterized by high efficiency, timeliness, selectivity, and no heating delay, and it is effective only for materials with specific dielectric properties. The advantages of using microwave heating atomization are: a) Microwave heating is radiant heating, not heat conduction, allowing for immediate stopping of the cigarette; b) There is no heating element, so there are no issues with chip breakage or cleaning the heating element; c) The aerosol matrix has high utilization rate, high consistency in taste, and a taste closer to that of cigarettes.

[0004] However, the use of RF connectors and cables as signal transmission components between the microwave cavity and the RF board, coupled with their high cost, results in a higher overall cost for heated non-combustible appliances. Furthermore, the routing of the RF cables is prone to interference with other components, making the manufacturing of heated non-combustible appliances more difficult. Summary of the Invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] In view of this, the present invention proposes an aerosol generating device, comprising: a housing having a resonant cavity; a resonant column located inside the resonant cavity, the first end of the resonant cavity being connected to the bottom wall of the resonant cavity, and the second end of the resonant cavity extending toward the opening of the resonant cavity; a radio frequency component connected to the housing; and a coupling member, the first end of which is coupled to the radio frequency component, and the second end of which is coupled to the resonant column or the inner wall of the resonant cavity.

[0007] The aerosol generating device provided by this invention includes a radio frequency component capable of generating microwaves. These microwaves are fed into a resonant cavity via a coupling element, where they act on an aerosol matrix to generate aerosols. The cavity wall is made of a metallic material or other highly conductive material. Exemplarily, the cavity wall is made of gold, silver, copper, aluminum, iron, gold-containing alloys, aluminum-containing alloys, copper-containing alloys, iron-containing alloys, stainless steel, etc. Alternatively, the cavity wall may include non-metallic materials and a metallic coating.

[0008] The resonant pillar can act as a conductor and can be made of metallic materials or other highly conductive materials. For example, the cavity wall of the resonant cavity may be made of gold, silver, copper, aluminum, iron, gold-containing alloys, aluminum-containing alloys, copper-containing alloys, iron-containing alloys, stainless steel, etc. Alternatively, the resonant pillar may include non-metallic materials and metallic coatings. The resonant pillar is used to transmit microwaves and improve microwave transmission rates. Microwaves are less prone to attenuation during propagation within the resonant cavity, thus improving the effectiveness of microwaves on the aerosol generating components. This allows microwaves to act on the aerosol generating components efficiently and rapidly, better meeting user needs.

[0009] The first end of the coupler is coupled to the RF output port of the RF component, and the second end of the coupler is coupled to the inner wall of the resonant pillar or resonant cavity, so that the microwaves generated by the RF component can be transmitted to the resonant cavity through the coupler.

[0010] The first end of the coupler is connected to the RF output port of the RF component, and the second end of the coupler is connected to the inner wall of the resonant pillar or resonant cavity. Compared with the RF connectors and RF cables used in related technologies between the resonant cavity and the RF component, this invention uses a coupler between the resonant cavity and the RF component for microwave conduction, saving RF connectors and cables and reducing the manufacturing cost of the aerosol generator. Furthermore, the coupler is typically a non-deformable structure, eliminating the need to consider wiring and routing issues; for example, the coupler can be a structure extending in one direction. The coupler is less likely to interfere with other components, thus reducing the layout difficulty of internal components in the aerosol generator and improving manufacturing complexity. Since the coupler does not need to avoid other components, no clearance space is required, thereby reducing the size of the aerosol generator and facilitating its miniaturization.

[0011] In one possible application, the coupling element is a conductive structure, and the second end of the coupling element can be designed as a spring pin or a fine thread structure, which is connected to the inner wall of the resonant column or resonant cavity through the spring pin or fine thread structure.

[0012] Radio frequency (RF) components include solid-state microwave sources, thus offering advantages such as frequency stability and precise power output.

[0013] By eliminating the need for RF connectors and cables, the number of components within the aerosol generator is reduced, resulting in a lighter aerosol generator. Compared to the wiring and routing methods used in related technologies, the microwave conduction path between the resonant cavity and the RF components in this invention is shorter, thus reducing circuit losses and improving the performance stability of the aerosol generator.

[0014] Moreover, since no RF connectors need to be installed on the RF components, the RF components are less likely to experience large forces on one side. The RF components are less likely to experience separation and detachment of internal components due to partial structural gravity eccentricity, which helps to improve the contact stability between components and thus ensure the functional stability of the aerosol generator.

[0015] In one possible application, since the coupler needs to conduct microwaves, it needs to be made into a conductive structure and can be made of materials such as gold, silver, copper, aluminum, iron, gold alloys, aluminum alloys, copper alloys, iron alloys, and stainless steel.

[0016] In addition, the aerosol generating device according to the above-described technical solution provided by the present invention may also have the following additional technical features:

[0017] In the above technical solution, the radio frequency component includes a radio frequency circuit board, a coupling element perpendicular to the central axis of the resonant cavity, and the radio frequency circuit board.

[0018] In this technical solution, the RF circuit board has a plate-like structure. The central axis of the resonant cavity and the RF circuit board are perpendicular to the coupling element, so the central axis of the resonant cavity and the RF circuit board are parallel. This arrangement allows the coupling element to connect the resonant cavity and the RF circuit board with minimal distance. By reducing the length of the coupling element, the distance between the resonant cavity and the RF circuit board can be shortened, thereby reducing the volume of the aerosol generator and facilitating product miniaturization.

[0019] In any of the above technical solutions, the radio frequency component further includes an electromagnetic shielding layer, and at least a portion of the radio frequency circuit board is located within the electromagnetic shielding layer.

[0020] In this technical solution, the radio frequency (RF) circuit board can serve as a microwave source, and an electromagnetic shielding layer covers at least a portion of the RF circuit board's surface. The electromagnetic shielding layer can shield electromagnetic signals, preventing the RF circuit board from electromagnetic interference and ensuring its operational stability.

[0021] In order for the coupler to be stably coupled to the RF circuit board, the first end of the coupler needs to be coupled to a position on the RF circuit board that is not covered by the electromagnetic shielding layer.

[0022] In any of the above technical solutions, the housing includes: a first body with a resonant cavity; a second body located on the side of the first body, the second body having a mounting cavity, a coupling member passing through the mounting cavity and extending into the resonant cavity, and the second body having a contact surface that contacts the radio frequency component.

[0023] In this technical solution, the second body has a mounting cavity, meaning it is a hollow structure that allows the coupling element to pass through. The contact surface of the second body contacts the radio frequency (RF) component, so the electromagnetic shielding layer blocks the opening of the mounting cavity. The RF component and the second body enclose a sealed space, within which the coupling element is located, effectively preventing electromagnetic interference. Furthermore, because the RF component and the second body form a sealed space, microwave leakage is less likely to occur, ensuring user safety when using the aerosol generator and avoiding energy waste.

[0024] The connection method between the second body and the radio frequency component has the advantages of good shielding performance and high microwave feed efficiency.

[0025] The second body is located on the side wall of the first body, which can reduce the length of the aerosol generator in one direction, making it easier for users to use or store the aerosol generator.

[0026] In any of the above technical solutions, the aerosol generating device further includes: a limiting groove, disposed on the inner wall of the resonant column or resonant cavity, and the second end of the coupling element extends into the limiting groove.

[0027] In this technical solution, the second end of the coupling element can extend into the limiting groove. The limiting groove limits the second end of the coupling element, preventing the coupling element from shaking and improving the stability during microwave feeding.

[0028] Specifically, the limiting groove can be set on the side wall of the resonant column, and the second end of the coupling element can be designed as an elastic structure to ensure stable contact between the coupling element and the limiting groove. Alternatively, the second end of the coupling element can be set as a threaded structure, allowing it to be connected to the inner wall of the limiting groove via threads, ensuring stable contact between the coupling element and the limiting groove.

[0029] The limiting groove can also be set on the inner wall of the resonant cavity, and the second end of the coupling element can be designed as an elastic structure to ensure stable contact between the coupling element and the inner wall of the resonant cavity. The second end of the coupling element can also be set as a threaded structure, so that the second end of the coupling element can be connected to the inner wall of the limiting groove through threads, ensuring stable contact between the coupling element and the inner wall of the resonant cavity.

[0030] In any of the above technical solutions, the coupling element includes: a first coupling part, the first end of which is coupled to the radio frequency component; a second coupling part, the first end of which is connected to the first end of the first coupling part, the second coupling part being in contact with the inner wall of the resonant column or resonant cavity, and the second coupling part having an included angle with the first coupling part.

[0031] In this technical solution, the coupling element is divided into two parts, specifically a first coupling part and a second coupling part, which have an included angle, meaning that a portion of the coupling element is a bent structure. The first coupling element is the bent structure within the coupling element. Setting a portion of the coupling element as a bent structure can increase the contact area between the coupling element and the resonant column or the inner wall of the resonant column, thereby improving the contact stability between the coupling element and the inner wall of the resonant column or resonant cavity.

[0032] In any of the above technical solutions, the first end of the coupler is detachably connected to the radio frequency component.

[0033] In this technical solution, the first end of the coupler can be detached from the radio frequency component, which facilitates the installation and removal of the coupler from the radio frequency component. When the coupler is damaged, it can be replaced separately, which can effectively reduce the maintenance cost of the aerosol generator.

[0034] In any of the above technical solutions, the first end of the coupling member is provided with a threaded hole, and the radio frequency component is provided with a through hole; the aerosol generating device further includes: a locking member, which passes through the through hole and is connected to the threaded hole.

[0035] In this technical solution, a threaded hole is provided at the first end of the coupling component, and a through hole is provided on the radio frequency component. The locking component can be a screw. The screw passes through the through hole and connects with the threaded hole at the first end of the coupling component, thereby locking the coupling component to the radio frequency component. The method of connecting the coupling component and the radio frequency component with a screw facilitates the assembly and disassembly of the two.

[0036] In other technical solutions, the first end of the coupling element can be connected to the radio frequency component by riveting, pressing, sleeve connection, or welding.

[0037] In any of the above technical solutions, the aerosol generating device further includes: a gasket located between the locking member and the radio frequency component.

[0038] In this technical solution, the locking component can lock the coupling component to the RF component. However, the direct contact between the locking component and the RF component can easily cause damage to the RF component due to stress.

[0039] A gasket is placed between the locking component and the RF component. The gasket can be an elastic gasket with a soft texture. Placing a gasket between the locking component and the RF component can avoid a rigid connection between the locking component and the RF component, which helps to reduce the damage rate of the RF component.

[0040] Specifically, the washer can be a ring structure, and the washer can be fitted onto the locking element.

[0041] In any of the above technical solutions, the aerosol generating device further includes: an insulating sleeve fitted onto the coupling element.

[0042] In this technical solution, since the coupling element is a conductive structure, an insulating sleeve is used to cover it to prevent short circuits. The insulating sleeve is made of insulating material, and the coupling element is located inside the insulating sleeve, which effectively prevents short circuits from occurring.

[0043] In any of the above technical solutions, the insulating sleeve includes a rigid tube.

[0044] In this technical solution, because the insulating sleeve is a rigid tube, it is not easily deformed by external forces. This allows the insulating sleeve to not only provide insulation but also protect the coupling components. Since the insulating sleeve is not easily deformed, it is less likely to come into contact with the coupling components, preventing damage to the coupling components from external forces and improving the structural stability of the aerosol generator.

[0045] In any of the above technical solutions, the outer wall of the insulating sleeve is in contact with the inner wall of the mounting cavity.

[0046] In this technical solution, the outer wall of the insulating sleeve can be tightly clamped to the inner wall of the mounting cavity, preventing the insulating sleeve from shaking relative to the mounting cavity and further improving the installation stability of the insulating sleeve. The insulating sleeve is less prone to shaking, thus preventing it from coming into contact with the coupling element and avoiding damage to the coupling element.

[0047] The insulating sleeve can be connected to the inner wall of the mounting cavity by interference fit or clearance fit.

[0048] In any of the above technical solutions, the housing is detachably connected to the radio frequency component.

[0049] In this technical solution, the housing and the radio frequency component are separate structures. The housing can be disassembled and installed on the radio frequency component. When the housing or the radio frequency component is damaged, the housing or the radio frequency component can be repaired or replaced separately, which can reduce the maintenance cost of the aerosol generator.

[0050] For example, a threaded hole can be provided on the second body, and a mounting hole can be provided on the radio frequency component, with a screw passing through the mounting hole and connecting to the threaded hole on the second body.

[0051] In any of the above technical solutions, the first body includes: a carrier; a fixed seat, the fixed seat and the carrier together form a resonant cavity, the fixed seat is detachably connected to the carrier, and the fixed seat is provided with a receiving cavity for accommodating the aerosol generating component.

[0052] In this technical solution, the mounting base can be detached from the support base. After prolonged use of the aerosol generator, when cleaning is required, the mounting base can be removed from the support base, thereby opening the resonant cavity and facilitating individual cleaning of the resonant cavity. This improves the ease of cleaning the aerosol generator and, consequently, enhances user convenience. Furthermore, in the event of damage to the aerosol generator, individual components can be replaced, reducing maintenance costs.

[0053] The aerosol generating component can be inserted into the receiving cavity, which limits the aerosol generating component, so that the aerosol generating component can be stably fixed to the aerosol generating device.

[0054] In any of the above technical solutions, a portion of the resonant pillar extends into the receiving cavity.

[0055] In this technical solution, the aerosol generating component is installed inside the receiving cavity. To prevent the aerosol generating component from separating from the receiving cavity, it can be plugged into a resonant column. The diameter of a portion of the resonant column located inside the receiving cavity can be smaller than the diameter of a portion of the resonant column located inside the resonant cavity, thereby facilitating the plugging function between the resonant column and the aerosol generating component.

[0056] In any of the above technical solutions, the resonant column is detachably connected to the inner wall of the resonant cavity.

[0057] In this technical solution, when the resonant column is damaged, it can be disassembled from the resonant cavity, and then the resonant column can be repaired or replaced separately, which helps to reduce the maintenance cost of the aerosol generator.

Detailed Implementation

[0065] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0066] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0067] The following reference Figures 1 to 3 The aerosol generating apparatus provided according to some embodiments of the present invention is described.

[0068] Combination Figure 1 and Figure 2 As shown, in some embodiments of the present invention, an aerosol generating device is proposed, comprising: a housing 100, a resonant column 200, a radio frequency component 300, and a coupling member 400. The housing 100 is provided with a resonant cavity 110; the resonant column 200 is located inside the resonant cavity 110, a first end of the resonant cavity 110 is connected to the bottom wall of the resonant cavity 110, and a second end of the resonant cavity 110 extends toward the opening of the resonant cavity 110; the radio frequency component 300 is connected to the housing 100; a first end of the coupling member 400 is coupled to the radio frequency component 300, and a second end of the coupling member 400 is coupled to the resonant column 200 or the inner wall of the resonant cavity 110.

[0069] The aerosol generator provided in this embodiment includes a radio frequency component 300 capable of generating microwaves. These microwaves are fed into a resonant cavity 110 via a coupling member 400. The microwaves within the resonant cavity 110 act on the aerosol matrix, thereby generating aerosols. The cavity wall of the resonant cavity 110 is made of a metallic material or other highly conductive material. For example, the cavity wall of the resonant cavity 110 may be made of gold, silver, copper, aluminum, iron, gold-containing alloys, aluminum-containing alloys, copper-containing alloys, iron-containing alloys, stainless steel, etc. Alternatively, the cavity wall of the resonant cavity 110 may include non-metallic materials and a metallic coating. The resonant cavity 110 may have a cylindrical, elliptical, or square shape.

[0070] The resonant post 200 can function as a conductor and can be made of metallic materials or other highly conductive materials. For example, the cavity wall of the resonant cavity 110 may be made of gold, silver, copper, aluminum, iron, gold-containing alloys, aluminum-containing alloys, copper-containing alloys, iron-containing alloys, stainless steel, etc. Alternatively, the resonant post 200 may include non-metallic materials and a metallic coating. The resonant post 200 is used to transmit microwaves and improve microwave transmission rates. Microwaves are less prone to attenuation during propagation within the resonant cavity 110, thus improving the effectiveness of microwaves on the aerosol generating component. This allows microwaves to act on the aerosol generating component efficiently and rapidly, which is beneficial for meeting user needs.

[0071] The first end of the coupling member 400 is coupled to the radio frequency output port of the radio frequency component 300, and the second end of the coupling member 400 is coupled to the resonant post 200 or the inner wall of the resonant cavity 110, so that the microwave generated by the radio frequency component 300 can be transmitted to the resonant cavity 110 through the coupling member 400.

[0072] The first end of the coupling element 400 is in contact with the RF output port of the RF component 300, and the second end of the coupling element 400 is in contact with the resonant pillar 200 or the inner wall of the resonant cavity 110. Compared with the RF connector and RF connection line between the resonant cavity 110 and the RF component 300 in related technologies, the present invention uses the coupling element 400 between the resonant cavity 110 and the RF component 300 for microwave conduction, which can reduce the processing cost of the aerosol generator. Moreover, the coupling element 400 is usually a non-deformable structure, so there is no need to consider the wiring and routing issues. For example, the coupling element 400 can be a structure that extends in one direction. The coupling element 400 is less likely to interfere with other components, thereby reducing the layout difficulty between internal components of the aerosol generator and helping to reduce the processing difficulty. Since the coupling element 400 does not need to avoid other components, there is no need to provide clearance space for other components, thus reducing the volume of the aerosol generator and facilitating the miniaturization of the aerosol generator.

[0073] By eliminating the need for RF connectors and RF cables, the number of components within the aerosol generator is reduced, resulting in a lighter aerosol generator. Compared to the wiring and routing methods used in related technologies, the microwave conduction path between the resonant cavity 110 and the RF component 300 in this invention is shorter, thus reducing circuit losses and improving the performance stability of the aerosol generator.

[0074] Furthermore, since no radio frequency connector is required on the radio frequency component 300, the radio frequency component 300 is less likely to experience excessive force on one side. The radio frequency component 300 is less likely to experience separation and detachment of internal components due to partial structural gravity eccentricity, which helps to improve the contact stability between components and thus ensures the functional stability of the aerosol generator.

[0075] In one possible application, since the coupler 400 needs to conduct microwaves, it needs to be configured as a conductive structure and can be made of materials such as gold, silver, copper, aluminum, iron, gold alloys, aluminum alloys, copper alloys, iron alloys, and stainless steel.

[0076] In one possible embodiment, the radio frequency component 300 includes a radio frequency circuit board, and the coupler 400 is perpendicular to the central axis of the resonant cavity 110 and the radio frequency circuit board.

[0077] In this embodiment, the radio frequency circuit board has a plate-like structure. The central axis of the resonant cavity 110 and the radio frequency circuit board are perpendicular to the coupling member 400, so the central axis of the resonant cavity 110 and the radio frequency circuit board are parallel. This arrangement allows the coupling member 400 to connect the resonant cavity 110 and the radio frequency circuit board with minimal distance. By reducing the length of the coupling member 400, the distance between the resonant cavity 110 and the radio frequency circuit board can be shortened, thereby reducing the volume of the aerosol generator and facilitating product miniaturization.

[0078] In one possible embodiment, the radio frequency component 300 further includes an electromagnetic shielding layer, with at least a portion of the radio frequency circuit board located within the electromagnetic shielding layer.

[0079] In this embodiment, the radio frequency (RF) circuit board can serve as a microwave source, and an electromagnetic shielding layer covers at least a portion of the RF circuit board's surface. The electromagnetic shielding layer can shield electromagnetic signals, preventing the RF circuit board from being subjected to electromagnetic interference, ensuring the operational stability of the RF circuit board, and extending the lifespan of the device.

[0080] In order for the coupling element 400 to be stably coupled to the radio frequency circuit board, the first end of the coupling element 400 needs to be coupled to a position on the radio frequency circuit board that is not covered by the electromagnetic shielding layer.

[0081] Combination Figure 1 and Figure 2As shown, in one possible embodiment, the housing 100 includes: a first body 120 and a second body 130. The first body 120 is provided with a resonant cavity 110. The second body 130 is disposed on the side of the first body 120 and is provided with a mounting cavity 131. The coupling member 400 passes through the mounting cavity 131 and extends into the resonant cavity 110. The second body 130 is provided with a contact surface that contacts the radio frequency component 300.

[0082] In this embodiment, the second body 130 is provided with a mounting cavity 131, meaning the second body 130 has a hollow structure, allowing the coupling member 400 to pass through the mounting cavity 131. The contact surface of the second body 130 is in contact with the radio frequency component 300, so the electromagnetic shielding layer blocks the opening of the mounting cavity 131. The radio frequency component 300 and the second body 130 enclose a sealed space, and the coupling member 400 is located within this sealed space, effectively preventing the coupling member 400 from being subjected to electromagnetic interference. Moreover, since the radio frequency component 300 and the second body 130 enclose a sealed space, microwave leakage is less likely to occur, ensuring the safety of the user in using the aerosol generator while avoiding energy waste.

[0083] The second body 130 is disposed on the side wall of the first body 120, which can reduce the length of the aerosol generator in one direction, making it easier for users to use or store the aerosol generator.

[0084] Specifically, the contact surface of the second body 130 is in direct contact with the RF body, meaning that the portion of the RF component 300 that needs to contact the contact surface is not provided with an electromagnetic shielding layer. Since the housing 100 is normally grounded, the RF body also achieves grounding functionality after the contact surface of the second body 130 contacts the RF body. This eliminates the need for an additional grounding metal structure, saving space and component cost associated with grounding components.

[0085] The connection method between the second body 130 and the radio frequency component 300 has the advantages of good shielding performance and high microwave feed efficiency.

[0086] In one possible embodiment, the aerosol generating device further includes a limiting groove, which is disposed on the inner wall of the resonant column 200 or the resonant cavity 110, and the second end of the coupling member 400 extends into the limiting groove.

[0087] In this embodiment, the second end of the coupling member 400 can extend into the limiting groove. The limiting groove limits the second end of the coupling member 400, preventing the coupling member 400 from shaking and improving the stability during microwave feeding.

[0088] Specifically, the limiting groove can be set on the side wall of the resonant column 200, and the second end of the coupling member 400 can be designed as an elastic structure to ensure stable contact between the coupling member 400 and the limiting groove. The second end of the coupling member 400 can also be set as a threaded structure, so that the second end of the coupling member 400 can be connected to the inner wall of the limiting groove through threads, ensuring stable contact between the coupling member 400 and the limiting groove.

[0089] The limiting groove can also be set on the inner wall of the resonant cavity 110, and the second end of the coupling member 400 can be designed as an elastic structure to ensure stable contact between the coupling member 400 and the inner wall of the resonant cavity 110. The second end of the coupling member 400 can also be set as a threaded structure, so that the second end of the coupling member 400 can be connected to the inner wall of the limiting groove through threads, ensuring stable contact between the coupling member 400 and the inner wall of the resonant cavity 110.

[0090] In one possible embodiment, the coupling member 400 includes: a first coupling portion and a second coupling portion, a first end of the first coupling portion being coupled to the radio frequency component 300; a first end of the second coupling portion being connected to the first end of the first coupling portion, the second coupling portion being in contact with the inner wall of the resonant pillar 200 or the resonant cavity 110, and the second coupling portion having an included angle with the first coupling portion.

[0091] In this embodiment, the coupling member 400 is divided into two parts, specifically a first coupling part and a second coupling part, which have an included angle, meaning that a portion of the coupling member 400 is a bent structure. The first coupling member 400 is a bent structure within the coupling member 400. Setting a portion of the coupling member 400 as a bent structure can increase the contact area between the coupling member 400 and the resonant column 200 or the inner wall of the resonant column 200, thereby improving the contact stability between the coupling member 400 and the resonant column 200 or the inner wall of the resonant cavity 110.

[0092] In one possible embodiment, the first end of the coupler 400 is detachably connected to the radio frequency assembly 300.

[0093] In this embodiment, the first end of the coupling member 400 can be detached from the radio frequency component 300, which facilitates the installation and removal of the coupling member 400 from the radio frequency component 300. When the coupling member 400 is damaged, it can be replaced separately, which can effectively reduce the maintenance cost of the aerosol generator.

[0094] Combination Figure 2 and Figure 3 As shown, in one possible embodiment, the first end of the coupling member 400 is provided with a threaded hole, and the radio frequency component 300 is provided with a through hole; the aerosol generating device further includes: a locking member 500, which passes through the through hole and is connected to the threaded hole.

[0095] In this embodiment, a threaded hole is provided at the first end of the coupling member 400, a through hole is provided on the radio frequency component 300, and the locking member 500 can be a screw. The screw is used to pass through the through hole and connect with the threaded hole at the first end of the coupling member 400, thereby locking the coupling member 400 to the radio frequency component 300. The method of connecting the coupling member 400 and the radio frequency component 300 with a screw facilitates the assembly and disassembly of the two.

[0096] In other embodiments, the first end of the coupling member 400 can be connected to the radio frequency component 300 by riveting, pressing, sleeve, or welding.

[0097] In one possible embodiment, the aerosol generating device further includes a gasket located between the locking member 500 and the radio frequency component 300.

[0098] In this embodiment, the locking member can lock the coupling member 400 to the radio frequency component 300. Direct contact between the locking member and the radio frequency component 300 can easily cause damage to the radio frequency component 300 due to stress.

[0099] A gasket is placed between the locking component and the radio frequency component 300. The gasket can be an elastic gasket with a soft texture. Placing a gasket between the locking component and the radio frequency component 300 can avoid a rigid connection between the locking component and the radio frequency component 300, which helps to reduce the damage rate of the radio frequency component 300.

[0100] Specifically, the washer can be a ring structure, and the washer can be fitted onto the locking element.

[0101] Combination Figure 2 and Figure 3 As shown, in one possible embodiment, the aerosol generating device further includes an insulating sleeve 600, which is sleeved on the coupling member 400.

[0102] In this embodiment, since the coupling element 400 is a conductive structure, an insulating sleeve 600 is used to cover the coupling element 400 to avoid short circuits. The insulating sleeve 600 is made of insulating material, and the coupling element 400 is located inside the insulating sleeve 600, which can effectively prevent short circuits from occurring in the coupling element 400.

[0103] For example, the insulating sleeve 600 can be made of polytetrafluoroethylene, rubber, silicone, etc.

[0104] In one possible embodiment, the insulating sleeve 600 comprises a rigid tube.

[0105] In this embodiment, since the insulating sleeve 600 is a rigid tube, it is not easily deformed by external forces. This allows the insulating sleeve 600 to not only provide insulation but also protect the coupling element 400. Because the insulating sleeve 600 is not easily deformed, it is less likely to come into contact with the coupling element 400, preventing damage to the coupling element 400 from external forces and improving the structural stability of the aerosol generator.

[0106] In one possible embodiment, the outer wall of the insulating sleeve 600 is in contact with the inner wall of the mounting cavity 131.

[0107] In this embodiment, the outer wall of the insulating sleeve 600 can be tightly clamped to the inner wall of the mounting cavity 131, preventing the insulating sleeve 600 from shaking relative to the mounting cavity 131, and further improving the installation stability of the insulating sleeve 600. The insulating sleeve 600 is less prone to shaking, thus making it less likely for the insulating sleeve 600 to come into contact with the coupling member 400, preventing damage to the coupling member 400.

[0108] The insulating sleeve 600 can be connected to the inner wall of the mounting cavity 131 by means of interference fit or clearance fit.

[0109] In one possible embodiment, housing 100 is detachably connected to radio frequency assembly 300.

[0110] In this embodiment, the housing 100 and the radio frequency component 300 are separate structures. The housing 100 can be disassembled and installed on the radio frequency component 300. When the housing 100 or the radio frequency component 300 is damaged, the housing 100 or the radio frequency component 300 can be repaired or replaced separately, which can reduce the maintenance cost of the aerosol generating device.

[0111] like Figure 3 As shown, for example, a threaded hole can be provided on the second body 130, and a mounting hole can be provided on the radio frequency assembly 300. A bolt 700 is used to pass through the mounting hole and connect to the threaded hole on the second body 130.

[0112] Combination Figure 1 and Figure 2 As shown, in one possible embodiment, the first body 120 includes a support 121 and a fixed base 122, the fixed base 122 and the support 121 forming a resonant cavity 110, the fixed base 122 being detachably connected to the support 121, and the fixed base 122 having a receiving cavity 123 for receiving an aerosol generating component.

[0113] In this embodiment, the mounting base 122 is detachable from the support base 121. After prolonged use of the aerosol generator, when cleaning is required, the mounting base 122 can be detached from the support base 121, thereby opening the resonant cavity 110. This facilitates separate cleaning of the resonant cavity 110, improving the ease of cleaning the aerosol generator and thus enhancing user convenience. Furthermore, in the event of damage to the aerosol generator, individual components can be replaced, reducing maintenance costs.

[0114] The aerosol generating component can be inserted into the receiving cavity 123, which limits the aerosol generating component so that the aerosol generating component can be stably fixed to the aerosol generating device.

[0115] The mounting base 122 needs to be made of plastic products with high mechanical strength, such as polycarbonate (PC), polylactic acid (PLA), polyetheretherketone (PEEK), etc.

[0116] The receiving cavity (123) can be equipped with a fixed bracket 124, which can support and limit the aerosol generating components. The fixed bracket 124 must be made of a low dielectric loss material, such as polyetheretherketone, polytetrafluoroethylene, microwave transparent ceramic, glass, silicon carbide, etc.

[0117] like Figure 2 As shown, in one possible embodiment, a portion of the resonant post 200 extends into the receiving cavity 123.

[0118] In this embodiment, the aerosol generating component is installed in the receiving cavity 123. To prevent the aerosol generating component from separating from the receiving cavity 123, the aerosol generating component can be plugged into the resonant post 200. The diameter of a portion of the resonant post 200 located in the receiving cavity 123 can be smaller than the diameter of a portion of the resonant post 200 located in the resonant cavity 110, thereby facilitating the plugging function between the resonant post 200 and the aerosol generating component.

[0119] In one possible embodiment, the resonant post 200 is detachably connected to the inner wall of the resonant cavity 110.

[0120] In this embodiment, when the resonant column 200 is damaged, the resonant column 200 can be disassembled from the resonant cavity 110, and then the resonant column 200 can be repaired or replaced separately, which helps to reduce the maintenance cost of the aerosol generator.
