Description

Technical Field

[0001] This application relates to the field of aerosol supply technology, and in particular to an aerosol supply device and system. Background Technology

[0002] In existing heated non-combustible aerosol supply devices, the heating module and the aerosol product (i.e., cigarette) are encased in the inner surface of a high-temperature resistant plastic structure (usually PEEK plastic, i.e., polyether ether ketone). At the same time, the outer surface of this plastic structure is covered with a layer of sheet-like aerogel material to achieve a certain degree of heat insulation. Finally, through mechanical cooperation, the plastic structure is fixed inside the entire outer shell of the aerosol supply device.

[0003] In the aforementioned designs, the thickness and length of the aerogel are limited by the internal structural design, resulting in inadequate thermal insulation. A significant portion of the heat is transferred from the high-temperature heating module to other components and the outer shell through internal heat conduction (including solid-to-solid and gas-to-solid heat conduction). Simultaneously, due to the compact internal structure and lack of high thermal conductivity heat dissipation paths, this leaked heat raises the overall temperature of the device without effectively dissipating to ambient temperature. Even with the use of heat-spreading sheets (thermally conductive metal or graphite) to improve heat dissipation, the considerable heat released by the aerosol supply device during operation causes continuous heat accumulation over time, leading to excessively high temperatures on the outer surface under certain conditions. This negatively impacts equipment safety and user experience.

[0004] Therefore, there is an urgent need to provide a new aerosol supply device to solve one or more of the above problems. Summary of the Invention

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an aerosol supply device and system to solve the technical problem of how to prevent the outer casing of the aerosol supply device from overheating during device operation.

[0006] In a first aspect, this application provides an aerosol supply device, the device comprising:

[0007] The outer shell has a first receiving cavity formed inside it;

[0008] A heat-insulating structure is disposed within the first accommodating cavity, and a second accommodating cavity for accommodating aerosol products is formed within the heat-insulating structure. A first gap exists between the outer shell and the heat-insulating structure, and the first gap communicates with the external environment.

[0009] In this embodiment, a first gap is provided between the insulation structure and the outer shell, and the first gap is connected to the external environment. During the heating process of the device, when the insulation structure receives heat from the heating leakage, its own temperature will rise above the ambient air temperature. The lower temperature air in the first gap comes into contact with the higher temperature insulation structure, and due to the temperature difference, an initial heat conduction effect is generated. The air in the first gap is heated and its temperature rises, causing the air in the first gap to form a natural thermal convection with the cold air in the outside environment. The heat is quickly exchanged to the outside atmosphere through fluid convection, thereby enabling the device to dissipate heat efficiently and preventing the outer shell temperature from becoming too high.

[0010] In one technical solution of the aforementioned aerosol supply device, the width of the first gap is 0.2-1.5 mm.

[0011] In one technical solution of the above-mentioned aerosol supply device, the first gap has a first opening at least at one longitudinal end of the device, and the first gap communicates with the external environment through the first opening.

[0012] In one technical solution of the above-mentioned aerosol supply device, the outer peripheral wall of the housing is provided with a vent hole that runs laterally through the outer peripheral wall of the device, and the vent hole connects the first gap with the external environment.

[0013] In one technical solution of the above-mentioned aerosol supply device, the ventilation holes are multiple and spaced apart on the outer peripheral wall of the housing.

[0017] In one technical solution of the aforementioned aerosol supply device, at least two of the plurality of vents are of different or the same size.

[0018] In one technical solution of the above-mentioned aerosol supply device, the device further includes an extractor or a heating tube, the extractor or the heating tube forming a third receiving cavity for accommodating the aerosol product, the extractor or the heating tube having a second opening at a first end in the length direction for inserting the aerosol product into the third receiving cavity, and an air inlet structure at the second end.

[0019] In one technical solution of the above-mentioned aerosol supply device, the first gap is connected to the air inlet structure.

[0020] In one technical solution of the above-mentioned aerosol supply device, the second end of the extractor or the heating tube has an end face connected to its circumferential sidewall, and a second gap is formed between the outer peripheral edge of the end face and the circumferential sidewall, the second gap forming at least part of the air intake structure.

[0021] In one technical solution of the above-mentioned aerosol supply device, the outer peripheral edge of the end face has a protrusion, one end of the protrusion is connected to the outer peripheral edge of the end face, and the other end is connected to the circumferential sidewall of the extractor or the heating tube.

[0022] The protrusions are multiple and arranged circumferentially at intervals along the outer peripheral edge of the end face, and the second gap is formed between adjacent protrusions.

[0023] In one technical solution of the above-mentioned aerosol supply device, the second end of the extractor or the heating tube has an end face connected to its circumferential sidewall, and the end face is provided with an axially penetrating through hole, the through hole forming at least part of the air intake structure.

[0024] In one technical solution of the above-mentioned aerosol supply device, a third gap is provided between the bottom of the heat insulation structure and the bottom surface of the first receiving cavity, and the third gap is connected to the air inlet structure.

[0025] In one technical solution of the above-mentioned aerosol supply device, the air intake structure and the first gap are connected through the third gap.

[0026] In one technical solution of the aforementioned aerosol supply device, a spacer is provided between the outer shell and the insulation structure to form the first gap.

[0027] In one technical solution of the above-mentioned aerosol supply device, the first end of the extractor or the heating tube is snapped onto the outer shell, and the heat insulation structure is sleeved on the outside of the extractor or the heating tube.

[0028] Through the embodiments of this application, the contact area between the insulation structure and components such as the outer shell can be minimized as much as possible, so that the heat conducted through the direct contact between the insulation structure and other components of the device can be controlled within a very small range. As a result, when the insulation structure is heated up under operating conditions, a large part of the heat will be trapped within the insulation structure itself and will not be quickly transferred out.

[0029] In one technical solution of the above-mentioned aerosol supply device, the heat insulation structure includes an inner shell, an outer shell, and a filling layer.

[0033] In a second aspect, this application provides an aerosol supply system, the system comprising at least the aerosol supply device as described in any of the first aspects.

[0034] The above-described technical solutions of this application have at least one or more of the following beneficial effects:

[0035] In implementing the technical solution of this application, a first gap is provided between the outer shell and the insulation structure, and the first gap is connected to the external environment. Thus, during the heating process, when the insulation structure receives heat from heat leakage, its temperature rises above the ambient air temperature. The cooler air in the first gap comes into contact with the warmer insulation structure, and due to the temperature difference, an initial heat conduction effect occurs. The air in the first gap is heated, and its temperature rises, causing natural thermal convection between the air in the first gap and the cold air in the external environment. Heat is rapidly exchanged to the outside atmosphere through fluid convection, thereby enabling efficient heat dissipation of the device and preventing the outer shell temperature from becoming too high.

The heater may, for example, comprise a combustible material, a material that can be heated by electrical conduction, or a sensor.

[0087] A sensor is a material that can be heated by being penetrated by a changing magnetic field (e.g., an alternating magnetic field). A sensor can be a conductive material, such that penetration by a changing magnetic field results in inductive heating of the heating material. A heating material can be a magnetic material, such that penetration by a changing magnetic field results in hysteresis heating of the heating material. A sensor can be both conductive and magnetic, allowing it to be heated by both heating mechanisms. In this paper, a device constructed to generate a changing magnetic field is referred to as a magnetic field generator.

[0088] Aerosol modifiers are substances typically located downstream of the aerosol generation region, configured to modify the generated aerosols, for example, by altering their taste, flavor, acidity, or other properties. Aerosol modifiers can be disposed in aerosol modifier release components operable to selectively release the aerosol modifier. For example, aerosol modifiers can be additives or adsorbents. For example, aerosol modifiers may include one or more of fragrances, colorants, water, and carbon adsorbents. For example, aerosol modifiers can be solid, liquid, or gel. Aerosol modifiers can be in powder, filament, or granular form. Aerosol modifiers may not contain filter material.

[0089] An aerosol generator is a device configured to cause the generation of aerosols from an aerosol-generating material. In some embodiments, an aerosol generator is a heater configured to subject the aerosol-generating material to heat energy in order to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, an aerosol generator is configured to cause the generation of aerosols from an aerosol-generating material without heating. For example, an aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0090] This disclosure relates to aerosol delivery systems (which may also be referred to as vapor delivery systems), such as aerosol sprayers or electronic cigarettes. In the following description, the terms "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that this term is used interchangeably with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Furthermore, as is common in the art, the terms "aerosol" and "vapor," as well as related terms such as "evaporation," "atomization," and "aerosolization," are generally used interchangeably.

[0091] Aerosol delivery systems (electronic cigarettes) typically (though not always) comprise modular components, including reusable device parts and replaceable (disposable / consumable) cartridge components. Typically, the replaceable cartridge component will include aerosol generating material and an vaporizer (which may be collectively referred to as an "atomizer"), and the reusable device part will include a power source (e.g., a rechargeable power source) and control circuitry. It will be understood that these different parts may include additional components depending on their function. For example, the reusable device part will typically include a user interface for receiving user input and displaying operational status characteristics, and the replaceable cartridge device part may include, in some cases, a temperature sensor to aid in temperature control. The cartridge is electrically and mechanically connected to the control unit for use, for example, using threads, bayonet connections, or magnetic connections with suitably arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable part, and a replacement cartridge can be attached to its appropriate position. Systems and devices that conform to this type of two-piece modular configuration can generally be referred to as two-piece systems / devices.

[0092] Electronic cigarettes typically have a generally elongated shape. For the sake of specific examples, some embodiments of this disclosure will be considered to include such a generally elongated two-piece system employing a disposable cartridge. However, it will be understood that the basic principles described herein can be equally applied to different constructions, such as single-piece systems or modular systems comprising more than two components, refillable devices and single-use disposable items, as well as other overall shapes, such as high-performance devices based on a so-called box-shaped pattern that typically has a box-like shape. More generally, it will be understood that some embodiments of this disclosure are based on aerosol delivery systems that are operatively configured to provide the functionality according to the principles described herein, and the construction aspects of the system configured to provide the functionality according to some embodiments of this disclosure are not of primary importance.

[0093] As described in the background section, existing heated non-combustible aerosol supply devices suffer from limitations in their internal structural design during operation, resulting in inadequate heat insulation. A significant portion of the heat is transferred from the high-temperature heating module to components such as the outer casing via internal heat conduction. Furthermore, due to the compact internal structure and lack of high thermal conductivity heat dissipation paths, this heat leakage raises the overall temperature of the device while failing to effectively conduct heat to the ambient temperature. As heating progresses, heat accumulates over time, causing the outer surface of the device to become excessively hot under certain conditions, thus impacting equipment safety and user experience.

[0094] To address one or more of the aforementioned problems, this application presents a novel aerosol supply device. This device features a first gap between the outer casing and the insulation structure, which is connected to the external environment. When the insulation structure receives heat from heat leakage, the heat conduction effect heats the air in the first gap, causing its temperature to rise. This leads to natural thermal convection between the air in the first gap and the cold air in the external environment, rapidly exchanging heat to the outside atmosphere through fluid convection. This results in efficient heat dissipation for the device and prevents the outer casing from overheating.

[0095] It should be noted that the aerosol supply device provided in this application does not specifically limit the heating method used, which includes, but is not limited to, the following methods: center needle heating (such as resistance, inductive, etc.), center plate heating (such as resistance, inductive, etc.), peripheral heating (such as resistance, inductive, infrared radiation, etc.), mixed heating (such as center / peripheral mixed heating, etc.) and other heating methods (such as airflow heating, etc.).

[0096] The following describes the solution of this application in detail using an aerosol supply device with a central needle heating method.

[0097] Example 1

[0098] Figure 1 This is a three-dimensional structural schematic diagram of the aerosol supply device and aerosol product provided in the embodiments of this application. Figure 2 This is a cross-sectional view of the aerosol supply device provided in the embodiments of this application. Figure 3 This is an exploded view of the aerosol supply device provided in the embodiments of this application, with reference to... Figures 1 to 3As shown, it generally includes a housing 100, an extractor 200, a heat insulation structure 300, and a heating module 400. The housing 100 has a first receiving cavity 110 inside, within which the extractor 200, heat insulation structure 300, and heating module 400 are housed. The heat insulation structure 300 has a second receiving cavity 360 inside, which houses the extractor 200. A first gap 600 exists between the housing 100 and the heat insulation structure 300, and this gap 600 communicates with the external environment. This allows the heat insulation structure to receive heat from heat leakage, which, due to thermal conduction, heats the air in the first gap, causing a rise in temperature. This leads to natural thermal convection between the air in the first gap and the cooler air in the external environment, rapidly exchanging heat to the outside atmosphere through fluid convection. This efficient heat dissipation prevents the housing temperature from becoming too high.

[0099] It should be noted that the embodiments of this application do not specifically limit the width of the first gap 600. Without departing from the inventive concept of this application, it can be set according to the actual needs of the product. As an exemplary rather than restrictive illustration, in the embodiments of this application, the width of the first gap 600 is any value between 0.2 and 1.5 mm. For example, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, etc., and will not be listed exhaustively here.

[0100] Further reference Figure 1 As shown, in some specific embodiments, the first gap 600 has a first opening 610 at one longitudinal end of the device, and the first gap 600 communicates with the external environment through the first opening 610. It is understood that the specific location of the first opening 610 is not limited in this embodiment, as long as it enables communication between the first gap 600 and the external environment. As an illustrative rather than restrictive description, the first opening 610 is located at the end of the first gap 600 facing the user.

[0101] Further reference Figure 1 and Figure 2 As shown, in a preferred embodiment, the outer peripheral wall of the outer shell 100 is provided with a vent 120, which penetrates the outer peripheral wall of the outer shell 100 laterally along the device, so that the vent 120 can connect the first gap 600 with the external environment.

[0102] In this embodiment, the number and size of the vents 120 are not limited. They can be set according to actual needs without departing from the inventive concept of this application. It is understood that a greater number and / or larger size of the vents 120 facilitates natural thermal convection between the air in the first gap 600 and the cold air in the external environment, thus promoting heat dissipation. Based on this, in some specific embodiments, multiple vents 120 are spaced apart on the outer peripheral wall of the outer casing 100.

[0103] In this embodiment, the arrangement of the vents 120 on the outer peripheral wall of the housing 100 is not specifically limited. In some specific embodiments, there are multiple vents 120 distributed at intervals along the longitudinal direction of the device on the outer peripheral wall of the housing 100; in other specific embodiments, there are multiple vents 120 distributed at intervals along the circumferential direction of the device on the outer peripheral wall of the housing 100. In still other specific embodiments, the outer peripheral wall of the housing 100 has a hollow structure, that is, the multiple vents on the outer peripheral wall of the housing 100 form a hollow structure, and the first gap 600 communicates with the external environment through the hollow structure, thereby allowing gas exchange between the first gap 600 and the external environment through the hollow structure.

[0104] It should be noted that the size of the vent 120 is not specifically limited in the embodiments of this application. It can be set according to actual product requirements without departing from the inventive concept of this application. In some specific embodiments, different vents 120 may be set to the same size; in other specific embodiments, different vents 120 may be set to different sizes; in still other specific embodiments, some vents 120 may be set to the same size, while others may be set to different sizes.

[0105] In some specific embodiments, the outer peripheral wall of the housing 100 may be subjected to at least one of the following treatments: smooth surface, frosted surface, anodized surface, brushed surface, coated surface, electroplated surface.

[0106] In some specific embodiments, in addition to providing a certain number of vent holes 120 on the outer peripheral wall of the outer shell 100, other structures can also be provided, such as a certain number of countersunk holes, protrusions, raised characters, recessed characters, etc., which will not be listed here.

[0107] It is understood that the embodiments of this application do not specifically limit the geometry of the outer shell 100. Any such outer shell arranged parallel to the axis of the aerosol product should be considered within the scope of this design. For example, the cross-sectional shape of the outer shell 100 along the axis perpendicular to the aerosol product can be divided into circular cross-section, elliptical cross-section, polygonal cross-section, irregular straight-sided cross-section, irregular curved cross-section, variable cross-section along the axis, etc.

[0108] In some specific embodiments, the assembly of the housing 100 and the device can be performed in at least one of the following ways: snap-fit ​​fixing, slide groove fixing, threaded fastener fixing, housing self-thread fixing, interference fit fixing, magnetic attraction fixing, top block fixing, adhesive fixing, etc.

[0109] Further reference Figure 3 and Figure 4 As shown, the extractor in this embodiment differs from the extractor of a conventional centrally heated aerosol supply device in that the air intake method is a bottom-up design, with external gas entering the third receiving cavity 210 for inserting the aerosol article 500 from the bottom of the extractor 200. Specifically, the extractor 200 has a first end 260 and a second end 270 along its length, which are opposite ends of the extractor 200. The first end 260 has a second opening 220 communicating with the internal space of the third receiving cavity 210, and the second end 270 has an air intake structure 230. Due to the bottom-up airflow design, there is no need to provide grooves / protrusions on the walls of the extractor 200 to accommodate airflow, allowing the inner and outer walls of the extractor 200 to be a simple and smooth standard cylindrical shape.

[0110] It is understandable that the aerosol product 500 includes various rod-shaped or strip-shaped structures that can be inserted into the extractor 200 and heated to atomize and generate aerosols, such as those containing tobacco, those containing nicotine but not tobacco, and those containing neither tobacco nor nicotine, etc., which will not be listed here. The aerosol product 500 includes an aerosol generating matrix, which can generate aerosols after being heated and atomized by the heating module 400.

[0111] Understandably, the extractor 200 is designed with a bottom-up airflow path, allowing the airflow within it to move upwards. According to thermodynamic principles, under a certain pressure, the density of hot air is slightly less than that of cold air. Therefore, in the absence of significant external disturbances, if a temperature difference exists in the airflow field, the hot airflow will tend to rise, and the cold airflow will tend to move downwards. Under most normal operating conditions of the aerosol supply device, the aerosol product, i.e., the heat source, is always located at the upper end relative to the cold air in the initial section of the inlet duct. This means that the hot air in the third receiving chamber 210 or at the end of the airflow path will not spontaneously flow upwards from the end of the inlet duct like the hot air in the top-down inlet duct, resulting in continuous heat loss.

[0112] In a preferred embodiment, the diameter of the inner wall of the extractor 200 (i.e., the diameter of the third receiving cavity 210) is slightly smaller than the diameter of the heated aerosol product. This creates a slight interference fit after the aerosol product is placed inside, ensuring a close fit between the aerosol product and the inner wall of the third receiving cavity 210, preventing gaps that could trap air. Simultaneously, the smooth outer wall of the extractor 200 fits snugly against the inner wall of the insulation structure 300, improving the overall heat leakage control capabilities of both the extractor 200 and the insulation structure 300, thereby enhancing the thermal insulation effect of the aerosol product. Furthermore, the smooth inner and outer walls of the extractor 200 also contribute to its ease of cleaning and manufacturing.

[0113] Understandably, a small gap can be left between the insulation structure 300 and the extractor 200 for the removal and insertion of the extractor. Therefore, the insulation structure 300 and the extractor 200 can be considered to fit tightly together, thus providing a compact insulation space for the aerosol product 500 and the extractor 200 located at the axial position, reducing heat accumulation and heat leakage caused by redundant structures.

[0114] Further reference Figure 4 As shown, the air intake structure 230 includes a through hole 231, a second gap 232, an auxiliary air passage 233, and a protrusion 234. In a specific implementation, the second end 270 of the extractor 200 has an end face 271 connected to its circumferential sidewall. The through hole 231 is disposed on and penetrates the end face 271, connecting the internal space of the third receiving cavity 210 to the external environment. The second gap 232 is formed between the outer peripheral edge of the end face 271 and the circumferential sidewall, also connecting the internal space of the third receiving cavity 210 to the external environment. The protrusion 234 is disposed on the outer peripheral edge of the end face 271, with one end connected to the outer peripheral edge of the end face 271 and the other end connected to the circumferential sidewall of the extractor 200. Multiple protrusions 234 are arranged circumferentially at intervals along the outer peripheral edge of the end face 271, and the second gap 232 is formed between adjacent protrusions 234. The auxiliary air passage 233 extends radially along the bottom wall of the third receiving cavity 210 on the protrusion 234, and one end of the auxiliary air passage 233 is connected to the through hole 231, while the other end is connected to the external environment. This arrangement allows the intake structure 230 to have the characteristics of compact structure, high intake efficiency, excellent support effect, and low heat loss of the intake passage.

[0115] It is understood that there are multiple second gaps 232, which are arranged at circumferential intervals between the outer peripheral edge of the end face 271 and the circumferential sidewall of the extractor 200.

[0116] Reference Figure 5As shown, the extractor 200 also includes a concave-convex structure 240 disposed on the bottom wall of the internal space of the third receiving cavity 210. In a specific implementation, the concave-convex structure 240 includes a recessed portion 241 and a protruding portion 242 disposed at intervals. The recessed portion 241 communicates with the second gap 232, and the protruding portion 242 abuts against the aerosol product. This arrangement can reduce the retention of substances such as soot and condensate in the internal space of the third receiving cavity 210 (i.e., the heating cavity) during use. On the other hand, it allows the aerosol product to receive uniform support force on the entire bottom of the internal space of the third receiving cavity 210 when the user removes the extractor 200 from the device after inhalation, thereby minimizing the residue of the aerosol generating matrix on the heating needle and the shedding of the aerosol generating matrix in the extractor.

[0117] In some specific embodiments, both the recessed portion 241 and the protruding portion 242 include multiple portions, and the multiple recessed portions 241 and the multiple protruding portions 242 are spaced apart. Each recessed portion 241 communicates with at least one second gap 232.

[0118] It is understandable that the air intake structure 230 is connected to the first gap 600, so that the air intake structure 230 can be connected to the external environment through the first gap 600, thereby allowing the air from the external environment to enter the third receiving cavity 210 in sequence through the first gap 600 and the air intake structure 230.

[0119] Further reference Figure 3 and Figure 4 As shown, in a preferred embodiment of this application, the extractor 200 further includes a gripping ring 250. The gripping ring 250 extends radially outward from the second opening 220 along the third receiving cavity 210. Preferably, the diameter of the gripping ring 250 is set to be larger than the diameter of the third receiving cavity 210, and the thickness of the gripping ring 250 is set to be greater than the thickness of the sidewall of the third receiving cavity 210. It is understood that the large diameter and thick gripping ring 250 can improve the structural rigidity of the entire extractor 200, especially the top gripping part, thereby reducing its deformation and maintaining the stability and integrity of the overall structure when the user grips the extractor 200 forcefully or when the extractor 200 is dropped and impacted by the device as a whole.

[0120] In some specific embodiments, a weight-reducing groove 251 is provided on the surface of the grip ring 250 facing the air intake structure 230. The weight-reducing groove 251 reduces the structural weight of the grip ring 250 while maintaining its high strength and rigidity. Simultaneously, the presence of the grip ring 250 significantly reduces its cross-sectional area (heat conduction area) in all directions, thereby slowing the diffusion rate of high temperature from the extractor center to the grip ring 250, and thus reducing the user's perceived temperature of the grip ring 250 after heating cycles. It should be noted that the shape and size of the weight-reducing groove 251 are not specifically limited in this embodiment; they can be designed according to actual product requirements without departing from the inventive concept of this application.

[0121] In a preferred embodiment of this application, the extractor 200, with one end of a gripping ring 250, is snapped onto the outer shell 100. Specifically, the extractor 200 is snapped onto the outer shell 100 via the gripping ring 250. A heat-insulating structure 300 is fitted over the extractor. In some specific embodiments, the heat-insulating structure 300 is interference-fitted with the second rib 900 on the base 800, ensuring no contact between the heat-insulating structure 300 and the outer shell 100, thereby reducing heat transfer to the outer shell 100 via the heat-insulating structure 300. In other specific embodiments, the heat-insulating structure 300 can be connected to the outer shell via snaps or other means, resulting in minimal contact between the heat-insulating structure 300 and the outer shell 100, further reducing heat transfer to the outer shell 100 via the heat-insulating structure 300.

[0122] Further reference Figure 3 As shown, the insulation structure 300 includes an inner shell 310, an outer shell 320, and a filling layer 330. The inner shell 310 and outer shell 320 cooperate to form a hollow structure, and the filling layer 330 is disposed within the hollow structure. It should be noted that the assembly method between the inner shell 310 and the outer shell 320 is not specifically limited in this embodiment. It can be set according to actual product requirements without departing from the inventive concept of this application. For example, in some specific embodiments, the inner shell 310 and outer shell 320 are integrally formed, creating a hollow structure between them.

[0123] In some specific embodiments, the inner shell 310 and / or the outer shell 320 are plastic layers. It is understood that both the inner shell 310 and the outer shell 320 are made of high-temperature resistant plastic materials, such as polyetheretherketone (PEEK), etc., without specific limitations.

[0124] In some specific embodiments, the filling layer 330 is an aerogel insulation material, such as silica aerogel, etc., but no specific limitation is made here.

[0125] In a preferred embodiment of this application, the thickness of the filling layer 330 is any value between 0.1 and 1.5 mm, such as 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, etc., which will not be listed exhaustively here. More preferably, the thickness of the filling layer 330 can be set to any value between 1.0 and 1.5 mm, such as 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, etc., which is thicker than conventional designs (usually 0.5 to 1.0 mm), thus resulting in better thermal insulation.

[0126] Further reference Figure 3 As shown, in a preferred embodiment of this application, the insulation structure 300 further includes a positioning block 340 and a buckle 350 disposed on the outer side wall of the outer shell 320. The positioning block 340 makes surface contact with the outer shell 100, thereby ensuring the coaxiality between the insulation structure 300 and the aerosol product axis. The buckle 350 cooperates with a pre-set groove on the outer shell 100 to form a buckle fixation, fixing the position of the insulation structure 300 in the device. At the same time, it also allows the integrated insulation structure 300 to be easily removed from the device when necessary, without affecting other fasteners of the device during removal, thus improving cleaning efficiency.

[0127] Understandably, through the above-mentioned arrangement, the contact surfaces between the insulation structure 300 and other components of the device are limited to the small contact areas between the positioning block 340 and the buckle 350 and the outer shell 100, and the small contact area between the insulation structure 300 and the first rib on the bottom wall. The total area of ​​these contact surfaces is a very small proportion compared to the total surface area of ​​the insulation structure 300, thus creating a kind of suspension-like fixation method. This arrangement, on the one hand, allows the heat conducted through direct contact between the insulation structure 300 and other components of the device to be controlled within a very small range. Therefore, when the insulation structure 300 is heated under operating conditions, a large portion of the heat will be trapped within the insulation layer itself and will not be quickly transferred out. In simpler terms, even if the temperature of the insulation structure 300 rises significantly, it cannot cause the surrounding components to heat up rapidly. On the other hand, some heat still diffuses outward from the insulation structure 300. However, in the above design, this part of the heat can only be spread through infrared thermal radiation and convection with the outside air. With the assistance of the specially designed shell 100, neither of these two heat transfer methods will cause the shell 100 and other components to heat up rapidly, nor will they significantly increase the temperature perceived by the user when holding the device.

[0128] It should be noted that this application does not specifically limit the number of positioning blocks 340 and buckles 350. Without departing from the inventive concept of this application, the number can be set according to actual product needs. As an illustrative rather than restrictive description, the positioning blocks 340 and buckles 350 in the embodiments of this application include multiple units, which are spaced apart along the circumference of the insulation structure 300 on the outer side wall of the outer shell 320.

[0129] In a preferred embodiment, in this application, the dimension of the filler layer 330 in the longitudinal direction of the insulation structure 300 extends beyond the top of the region corresponding to the aerosol generating matrix of the aerosol product and at least beyond the bottom of the aforementioned region. Preferably, the dimension of the filler layer 330 in the longitudinal direction of the insulation structure 300 may extend at least 10 mm beyond the top of the region corresponding to the aerosol generating matrix of the aerosol product and at least 5 mm beyond the aforementioned bottom. It is understood that the heating module 400 of the aerosol supply device using a center-needle heating method typically includes a heating needle 410, which is used to insert into the aerosol generating matrix of the aerosol product 500 to heat it and generate aerosol. The dimension of the filler layer 330 in the longitudinal direction of the insulation structure 300 extends beyond the top of the heating needle 410, preferably at least 10 mm, and at least beyond the bottom of the heating needle 410, preferably at least 5 mm, thereby making the coverage of the filler layer 330 in the longitudinal direction of the device far exceed that of conventional designs, further improving the insulation effect.

[0130] Reference Figure 6 As shown, in a preferred embodiment, a third gap 1100 is provided between the bottom of the insulation structure 300 and the bottom wall of the first receiving cavity 110, and the third gap 1100 is connected to the air intake structure 230. It is understood that in this embodiment, the third gap 1100 is connected to the first gap 600, allowing the air intake structure 230 to connect with the external environment via the third gap 1100 and the first gap 600. This allows air from the external environment to enter the third gap 1100 via the first gap 600, then enter the air intake structure 230 via the third gap 1100, and finally enter the internal space of the third receiving cavity 210 via the air intake structure 230.

[0131] Reference Figure 7 As shown, in some specific embodiments, the bottom of the thermal insulation structure 300 and the bottom wall of the first receiving cavity 110 are provided with a first rib 700. The first rib 700 extends longitudinally along the bottom wall of the first receiving cavity 110, so that the aforementioned third gap 1100 is formed between the bottom of the thermal insulation structure 300 and the bottom wall of the first receiving cavity 110.

[0132] Understandably, since the bottom of the insulation structure 300 only contacts the first rib 700 on the bottom wall of the first receiving cavity 110, and the contact area is much smaller than the area of ​​the bottom surface of the insulation structure 300, a structure similar to a suspended support is formed between the insulation structure 300 and the bottom wall of the first receiving cavity 110. This allows the heat conducted through the direct contact between the insulation structure 300 and other components of the device to be controlled within a very small range. Consequently, when the insulation structure 300 is heated under operating conditions, a large portion of the heat will be trapped within the insulation layer itself and will not be quickly transferred out.

[0133] It should be noted that the number of first ribs 700 is not specifically limited in this embodiment. Without departing from the inventive concept of this application, the number can be set according to actual product requirements. As an illustrative rather than restrictive description, the first ribs 700 in this embodiment include multiple ribs. These multiple first ribs 700 are spaced apart along the circumference of the insulation structure 300 on the bottom wall of the first receiving cavity 110, and the aforementioned third gap 1100 is formed between adjacent first ribs 700.

[0134] Further reference Figure 2 , Figure 3 and Figure 7 As shown, in a preferred embodiment of this application, the device further includes a base 800, which is disposed at the bottom of the first receiving cavity 110. On one hand, the bottom end of the extractor 200 is supported on the top surface of the base 800. On the other hand, a heat insulation structure 300 is sleeved on the outer peripheral wall of the base 800, and a fourth gap 1200 is formed between the inner wall of the heat insulation structure 300 and the outer peripheral wall of the base 800. The fourth gap 1200 communicates with the third gap 1100, thereby allowing the fourth gap 1200 to communicate with the external environment. It can be understood that in this embodiment, the fourth gap 1200 is connected to the air intake structure 230, so that the air intake structure 230 communicates with the external environment sequentially through the fourth gap 1200, the third gap 1100, and the first gap 600. This allows air from the external environment to enter the air intake structure 230 sequentially through the first gap 600, the third gap 1100, and the fourth gap 1200, and then enter the internal space of the third receiving cavity 210 through the air intake structure 230.

[0135] Further reference Figure 7As shown, in some specific embodiments, a second rib 900 is provided between the outer peripheral wall of the base 800 and the inner wall of the insulation structure 300. The second rib 900 extends along the length direction of the device, so that the aforementioned fourth gap 1200 is formed between the inner wall of the insulation structure 300 and the outer peripheral wall of the base 800. It should be noted that the number of second ribs 900 is not specifically limited in this application embodiment. Without departing from the inventive concept of this application, it can be set according to actual product needs. As an exemplary and not restrictive description, the second ribs 900 in this application embodiment include multiple second ribs 900, which are arranged at intervals along the circumference of the base 800 on the outer peripheral wall of the base 800, and the aforementioned fourth gap 1200 is formed between adjacent second ribs 900.

[0136] In some specific embodiments, a light ring 1400 is provided between the base 800 and the bottom of the first receiving cavity 110. Further, the light ring 1400 is positioned near the air intake structure 230, allowing the air intake structure 230 to simultaneously serve as a light inlet. Thus, even when the extractor 200 is placed inside the housing, the light ring 1400 can still provide illumination to the interior of the extractor 200. Preferably, the annular surface of the light ring 1400 is arranged parallel to the lower end face of the extractor 200. The device has multiple different lighting zones. When the extractor 200 is in different installation states, the light ring 1400 will illuminate different lighting zones, allowing the user to conveniently and intuitively inspect the internal conditions of the aerosol supply device at any time, so as to promptly eliminate abnormalities such as foreign objects or cigarette residue within the cavity.

[0137] It should be noted that the specific setting of the lighting effect area is not limited in the embodiments of this application. Without violating the inventive concept of this application, users can set it according to actual product needs.

[0138] It is understood that, in some preferred embodiments, buttons can also be provided on the device to control the opening or closing of the light ring 1100. In some specific embodiments, the buttons can be one or more combinations of mechanical rebound buttons, capacitive touch buttons, and capacitive touch and vibration feedback buttons. In other specific embodiments, the buttons can also be one or more combinations of mechanical knobs, mechanical rollers, and electromagnetic rollers; no specific limitations are made here.

[0139] In some specific embodiments, the base 800 may be made of high-temperature resistant PEEK plastic, but this application does not specifically limit it.

[0140] In a preferred embodiment, the outer shell 100 is made of at least one of the following materials: metal, polymer, natural, or composite. No specific limitations are imposed, and users can choose the appropriate material based on their needs. Metal materials include stainless steel, titanium alloy, and aluminum-magnesium alloy; polymer materials include various engineering plastics, PEEK, PC, and PP; natural materials include stone, bamboo, and wood; and composite materials include glass fiber reinforced resin and carbon fiber reinforced resin. These will not be listed exhaustively here.

[0141] Further reference Figure 3 As shown, in some specific embodiments, a spacer 1000 is provided between the outer shell 100 and the insulation structure 300, so that the aforementioned first gap 600 is formed between the outer shell 100 and the insulation structure 300. It should be noted that in the embodiments of this application, the location, shape, and size of the spacer 1000 are not specifically limited. Without departing from the inventive concept of this application, it can be set according to actual product requirements. In some specific embodiments, the spacer 1000 can be disposed on the inner wall of the outer shell 100 or integrally formed with the inner wall of the outer shell 100; in other specific embodiments, the spacer 1000 can be disposed on the outer wall of the insulation structure 300 or integrally formed with the outer wall of the insulation structure 300.

[0142] As a preferred embodiment, in this application embodiment, the spacer 1000 can be integrally formed with the positioning block 340, that is, the positioning block 340 serves as a spacer between the outer shell 100 and the insulation structure 300, thereby further reducing the contact area between the outer shell 100 and the insulation structure 300 and reducing the heat transfer between the insulation structure 300 and the outer shell.

[0143] Further reference Figure 2 and Figure 3 As shown, in a preferred embodiment of this application, the heating module 400 includes a heating needle 410, a heat-insulating base 420, and a heat-insulating layer 430. The heating needle 410 is located at the center of the end of the heat-insulating base 420 facing the extractor 200. The base 800 surrounds the outside of the heat-insulating base 420, and the heat-insulating layer 430 fills the space between the base 800 and the heat-insulating base 420. The heat-insulating layer 430 can be made of aerogel insulation material. The presence of the heat-insulating layer 430 can significantly reduce the diffusion of a small portion of the heat that freely travels in the air intake duct to the sidewalls of the air intake duct.

[0144] It is understandable that, for the cross-section of the fourth gap 1200 along the transverse direction of the device, its outer ring is surrounded by the insulation structure 300, and its inner ring is also surrounded by the insulation layer 430. Therefore, the higher temperature air inside the fourth gap 1200 is surrounded by insulation material on both sides, which greatly reduces the rate of heat transfer from the higher temperature air inside the fourth gap 1200 to the outside and improves the overall insulation efficiency of the system.

[0145] It should be noted that the embodiments of this application do not specifically limit the thermal insulation base 420. Without departing from the inventive concept of this application, it can be set according to actual needs. For example, the thermal insulation base 420 can be a ceramic base, etc.

[0146] In summary, through the solution provided in this application embodiment, although the heat leaking from the insulation structure 300 during the device heating process causes the overall temperature of the insulation structure 300 to gradually increase with the heating process, this leaked heat does not diffuse gradually through the mutual thermal conduction of the internal structure of the device, as is the case with conventional aerosol supply devices, where the heat only dissipates and cools down at a low rate through contact between the outer surface of the device and the air after the overall temperature of the device has increased significantly. In stark contrast, in the aerosol supply device provided in this application embodiment, when the insulation structure 300 receives heat from the heating leakage, its own temperature rises above the ambient air temperature. Simultaneously, the air within the first gap 600, because it remains connected to the atmosphere (ideally, before the device starts working, the air pressure and temperature within the first gap 600 are the same as the ambient air), will experience an initial thermal conduction effect due to the temperature difference when the lower-temperature air in the first gap 600 contacts the higher-temperature insulation structure 300, causing the air near the boundary of the insulation structure 300 to be heated and its temperature to rise. Subsequently, the hot air near the boundary of the insulation structure 300 will create a temperature difference with the air in the outermost layer of the first gap 600. Driven by this fluid-fluid temperature field difference, the air in the first gap 600 will generate a natural thermal convection effect, causing the air in the flow field to rapidly exchange position, velocity / momentum and heat in the form of vortices, so that the heat is rapidly diffused from the insulation structure 300 to the entire air flow layer in the first gap 600.

[0147] Furthermore, since the air within the first gap 600 is connected to the outside, the air heated in the first gap 600 by the aforementioned process will continue to form natural thermal convection with the outside cold air through the numerous through-holes on the outer shell 100. This rapidly exchanges heat to the outside atmosphere via fluid convection. Consequently, cooler outside air is exchanged into the first gap 600 by the convection effect, replacing the existing air and engaging in a new round of heat exchange with the insulation structure 300. Throughout this process, the insulation structure 300 remains in continuous contact with the lower-temperature air, achieving efficient heat dissipation and avoiding the problem of a significant increase in the air layer temperature leading to a decrease in the temperature difference between the air layer and the insulation structure 300, thus reducing its heat transfer capacity. The flowing air layer within the first gap 600 can also form a dynamic thermal balance under the action of fluid heat transfer, maintaining a temperature significantly lower than the surface temperature of the insulation structure 300.

[0148] Furthermore, since the outer shell 100 is made of a highly thermally conductive material with numerous through-holes, there is a large surface area in actual contact between the outer shell 100 and the air layer that exchanges heat through convection. Therefore, while the air in the first gap 600 exchanges heat with the outside environment through convection, the solid-fluid two-phase contact between the hotter air and the cooler shell also brings a considerable heat conduction effect, making the outer shell 100 effectively act as a "heat dissipation fin," transferring some of the heat from the hot air to the outer shell 100. Because there is little direct contact between the outer shell 100 and the insulation structure 300, the resulting solid-solid heat conduction effect is extremely limited and almost negligible. Therefore, the heat transferred to the outer shell 100 through air heat transfer is limited in both rate and magnitude. In addition, the structure and material design of the outer shell 100 itself also facilitates heat dissipation. The combined result is that, under this design, the surface temperature of the outer shell 100 is significantly lower than that of the insulation structure 300, largely achieving thermal decoupling between the outer shell 100 and the heat source, and significantly improving the thermal management capability of the equipment.

[0149] It is understood that, since the heat dissipation effect of the aerosol supply device provided in this application embodiment strongly relies on the convective heat dissipation effect brought about by the open air layer, the heat dissipation / surface cooling capacity of the system is further improved compared with the standard test conditions under the following two conditions:

[0150] 1. Under specific conditions, when the temperature difference between the ambient atmosphere and the center of the heating needle of the device is greater (e.g., the ambient temperature is colder than the standard test temperature, or the heating power curve is artificially increased), the temperature difference between the insulation structure 300 and the ambient atmosphere will also be greater during the operation of the device, thus resulting in a stronger natural air convection effect. As a result, under the aforementioned specific conditions, the temperature difference between the insulation structure 300 and the ambient atmosphere and the temperature difference between the outer shell 100 and the insulation structure 300 are not directly proportional. For example, when the ambient temperature is stable at 25°C, and other conditions remain unchanged, tests are conducted by artificially controlling two heating powers: high and low. At low power, the highest temperature of the insulation structure 300 during the test is 45°C, while the highest temperature of the outer shell 100 is 30°C. At high power, when the highest temperature of the insulation structure 300 is 70°C, the highest temperature of the outer shell 100 is 40°C. That is to say, when the temperature difference between the insulation structure 300 and the ambient atmosphere increases by 25°C, the temperature difference between the outer shell 100 and the insulation structure 300 only increases by 10°C.

[0151] 2. When there is airflow unrelated to the device itself in the operating environment (such as natural wind in an open environment, forced airflow from near an air conditioner, etc.), the external airflow will work in conjunction with the device's own natural thermal convection to intensify the fluid convection heat dissipation effect under this design.

[0152] It should be noted that the aerosol supply device provided in this application embodiment includes not only the components mentioned above, but also a housing 1600, and all the components mentioned above are assembled on the housing 1600. It is understood that the housing 1600 also integrates some other components for the aerosol supply device, such as a microcontroller (MCU), a battery, control circuits, etc., which will not be described in detail here.

[0153] Reference Figure 8 As shown in this embodiment, the bottom of the body 1600 is provided with a mounting hole 1610. A first connecting hole 1620 and a second connecting hole 1630 are provided along the circumference of the mounting hole 1610 at its edge. The first connecting hole 1620 extends longitudinally along the body, and the second connecting hole 1630 extends laterally along the body. A third connecting hole 810 is provided at the end of the base 800 away from the heating needle 410. After the heating module 400 is assembled into the base 800, the base 800 is placed into the mounting hole 1610 of the body 1600. Then, bolts or other connectors are used to connect the first connecting hole 1620 and the third connecting hole 810, thereby fixing the base 800 onto the body 1600.

[0154] It is understandable that, in order to improve the stability of the installation of the base 800 and the body 1600, in some specific embodiments, the number of the first connection hole 1620 and the third connection hole 810 includes multiples.

[0155] In some specific embodiments, the device may also include a cover plate 1700, which is adapted to the mounting hole 1610. After the base 800 is assembled and fixed on the body 1600, the cover plate 1700 is placed into the mounting hole 1610, and then the cover plate 1700 is assembled and fixed on the body 1600 by bolts or other connecting parts.

[0156] In other specific embodiments, the aerosol supply device may also be a peripheral heating method. It is understood that when the aerosol supply device is a peripheral heating method, it does not have an extractor 200 and a heating needle, but instead has a heating tube. The structure of the heating tube can refer to the structure of the extractor in the embodiments of this application. Apart from this, the other structures of the aerosol supply device are the same as the relevant structures in the above embodiments. Specific details can be found in the foregoing descriptions and will not be repeated here.

[0157] Example 2

[0158] The difference from Embodiment 1 lies in the assembly method of the insulation structure 300' in this embodiment. (Refer to...) Figures 9 to 11 As shown in the embodiment of this application, the inner shell 310′ and the outer shell 320′ are two independent components, connected together and cooperating to form a hollow structure between them. The inner shell 310′ is provided with a first connector 311′, and the outer shell 320′ is provided with a second connector 321′. The first connector 311′ and the second connector 321′ can be connected by a snap-fit ​​mechanism, thereby achieving the connection between the inner shell 310′ and the outer shell 320′. It should be noted that the specific implementation of the first connector 311′ and the second connector 321′ in this embodiment is not limited; they can be set according to actual product requirements. For example, as an exemplary rather than restrictive illustration, in this embodiment, the first connector 311′ can be a connecting block, which extends laterally away from the inner shell 310′ on the outer side wall of the inner shell 310′, and the second connector 321′ can be a slot. When the inner shell 310′ and the outer shell 320′ are assembled together, the connecting block can be engaged in the slot, thereby fixing the inner shell 310′ and the outer shell 320′ together.

[0159] It should be noted that in this embodiment, the number of the first connector 311' and the second connector 321' is not limited, and users can set them according to actual product requirements. It is understood that in order to improve the reliability of the connection between the inner shell 310' and the outer shell 320', the number of both the first connector 311' and the second connector 321' can be set to at least two.

[0160] Further reference Figure 11 As shown, in a preferred embodiment, the insulation structure 300′ in this application embodiment further includes a top cover 370′. As an example, both the inner shell 310′ and the outer shell 320′ are hollow cylinders, and the top cover 370′ is annular. The diameter of the inner shell 310′ is smaller than the diameter of the outer shell 320′. After the inner shell 310′ and the outer shell 320′ are assembled together, a hollow structure is formed between them. The filling layer 330′ fills this hollow structure. The top cover 370′ is located at the end of the inner shell 310′ and the outer shell 320′ away from the heating module 400, to close the opening at the end of the hollow structure away from the heating module 400. Further reference... Figure 11 As shown, a flange 313' is provided at one end of the inner shell 310' near the heating module 400. The flange 313' extends along the lateral direction of the inner shell 310' away from the inner shell 310' on the outer side wall of the inner shell 310'. When the inner shell 310' and the outer shell 320' are assembled together, the flange 313' closes the opening of the hollow structure at the end near the heating module 400.

[0161] In some specific embodiments, a third connector 312' is further provided on the inner shell 310', and a fourth connector 371' is provided on the top cover 370'. The third connector 312' and the fourth connector 371' can be connected by snap-fit, thereby achieving the connection between the inner shell 310' and the top cover 370'. It should be noted that the specific implementation of the third connector 312' and the fourth connector 371' is not limited in this application embodiment, and can be set according to actual product requirements in specific implementation. For example, as an exemplary and not restrictive illustration, in this application embodiment, the third connector 312' can be a connecting block, and the fourth connector 371' can be a slot. When the inner shell 310' and the top cover 370' are assembled together, the connecting block can be snapped into the slot, thereby fixing the inner shell 310' and the top cover 370' together.

[0162] It should be noted that, in this embodiment, the number of the third connector 312' and the fourth connector 371' is not limited, and users can set them according to actual product requirements. It is understood that, in order to improve the reliability of the connection between the inner shell 310' and the top cover 370', the number of both the third connector 312' and the fourth connector 371' can be at least two.

[0163] It is understandable that the shape of the filling layer 330′ can be adaptively adjusted according to the shape of the hollow structure formed between the inner shell 310′ and the outer shell 320′. For example, the filling layer 330′ may have a notch reserved to accommodate the first connector 311′ and the second connector 321′, etc., which will not be elaborated here.

[0164] As an illustrative and not restrictive description, in the embodiment of this application, the insulation structure 300′ can be assembled by first fitting the filling layer 330′ onto the inner shell 310′, then fitting the outer shell 320′ onto the outer periphery of the filling layer 330′, and assembling and fixing it through the first connector 311′ and the second connector 321′. After the inner shell 310′ and the outer shell 320′ are assembled, the top cover 370′ is assembled and fixed to the inner shell 310′ through the third connector 312′ and the fourth connector 371′ to form a closed cavity.

[0165] Further reference Figure 9 As shown in the embodiments of this application, the device further includes a button 1500, which is configured to control the opening or closing of the lamp ring 1400. In some specific embodiments, the button can be one or more of a mechanical rebound button, a capacitive touch button, or a capacitive touch and vibration feedback button. In other specific embodiments, the button can also be one or more of a mechanical knob, a mechanical roller, or an electromagnetic roller; no specific limitations are made here.
