Description

Technical Field

[0001] The present application relates to the technical field of aerosol supply, and in particular to an aerosol supply device and system. Background Art

[0002] During operation of the existing heat-not-burn aerosol supply device, the heating module and the aerosol product (i.e., cigarette) are wrapped in the inner surface of a high-temperature resistant plastic structure (usually PEEK plastic, i.e., polyetheretherketone). At the same time, the outer surface of the plastic structure is covered with a layer of sheet aerogel material to achieve a certain degree of thermal insulation performance. Finally, through mechanical matching, the plastic structure is fixed inside the outer shell of the entire aerosol supply device.

[0003] In the above-mentioned type of design, since the thickness and length of the aerogel are limited by the internal structural design of the body, a good thermal insulation effect cannot be achieved. A considerable amount of heat will be transferred from the high-temperature heating module to other parts of the body and the outer shell surface of the body through the heat conduction inside the body (including solid-solid heat conduction and gas-solid heat conduction in the body). At the same time, due to the compact internal structure of the body and the lack of a high thermal conductivity heat dissipation path, this part of the leaked heat increases the overall temperature of the body and cannot be well conducted to the normal temperature environment. Even if some designs use a heat-dissipating sheet (thermal conductive metal or graphite material) to improve the heat dissipation capacity, the aerosol supply device releases considerable heat in the working condition. Therefore, as the heating progresses, the heat will continue to accumulate over time, causing the temperature of the outer surface of the body to be too high under certain conditions, thereby affecting the safety of the equipment and the 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. Utility Model Content

A consumable may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol generating material to generate an aerosol. The heater may, for example, include a combustible material, a material that can be heated by electrical conduction, or a susceptor.

[0086] A susceptor is a material that can be heated by being penetrated with a varying magnetic field (e.g., an alternating magnetic field). The susceptor can be a conductive material such that its penetration by the varying magnetic field results in inductive heating of the heated material. The heated material can be a magnetic material such that its penetration by the varying magnetic field results in hysteresis heating of the heated material. The susceptor can be both conductive and magnetic such that the susceptor can be heated by both heating mechanisms. In this article, a device configured to generate a varying magnetic field is referred to as a magnetic field generator.

[0087] Aerosol modifiers are substances typically located downstream of an aerosol generation region that are configured to modify the generated aerosol, for example by changing the taste, flavor, acidity, or another characteristic of the aerosol. The aerosol modifier may be disposed in an aerosol modifier release component that is operable to selectively release the aerosol modifier. For example, the aerosol modifier may be an additive or an adsorbent. For example, the aerosol modifier may include one or more of a flavoring, a coloring agent, water, and a carbon adsorbent. For example, the aerosol modifier may be a solid, a liquid, or a gel. The aerosol modifier may be in powder, string, or particle form. The aerosol modifier may be free of filter material.

[0088] An aerosol generator is a device configured to cause an aerosol to be generated from an aerosol generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol generating material to thermal energy so as to release one or more volatiles from the aerosol generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be generated from the aerosol generating material without heating. For example, the aerosol generator can be configured to subject the aerosol generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0089] The present disclosure relates to an aerosol delivery system (which may also be referred to as a vapor delivery system), such as a nebulizer or an electronic cigarette. In the following description, the term "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that this term can be used interchangeably with aerosol delivery system / device and electronic aerosol delivery system / device. In addition, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "evaporation", "aerosolization" and "aerosolization" are often used interchangeably.

[0090] Aerosol delivery systems (electronic cigarettes) typically (although not always) include modular components, which include a reusable device part and a replaceable (disposable / consumable) cartridge part. Typically, the replaceable cartridge part will include an aerosol generating material and a vaporizer (which can be collectively referred to as an "atomizer"), and the reusable device part will include a power source (e.g., a rechargeable power source) and a control circuit. It will be understood that these different parts may include additional elements depending on the function. For example, the reusable device part will typically include a user interface for receiving user input and displaying operating status features, and the replaceable cartridge device part includes a temperature sensor for helping to control the temperature in some cases. The cartridge is electrically and mechanically connected to the control unit for use, for example, using a thread, a bayonet, or a magnetic connection with appropriately arranged electrical contacts. When the aerosol generating material in the cartridge is exhausted, 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 the replacement cartridge is attached to its appropriate position. Systems and devices conforming to this type of two-piece modular configuration may generally be referred to as two-piece systems / devices.

[0091] Electronic cigarettes typically have a generally elongated shape. To provide a specific example, some embodiments of the present disclosure will be considered to include such a generally elongated two-piece system using a disposable cartridge. However, it will be understood that the basic principles described herein may be equally applicable to different configurations, such as a one-piece system or a modular system including more than two components, a refillable device and single-use disposables, and other overall shapes, such as high-performance devices based on so-called box-shaped models that typically have a box shape. More generally, it will be understood that certain embodiments of the present disclosure are based on an aerosol delivery system that is operationally configured to provide functionality according to the principles described herein, and that the structural aspects of the system configured to provide functionality according to certain embodiments of the present disclosure are not primarily important.

[0092] As described in the background technology, the existing heat-not-burn aerosol supply device is limited by the design of the internal structure of the main body during operation, and the existing insulation structure cannot achieve a good insulation effect. A considerable amount of heat will be transferred from the high-temperature heating module to the outer shell and other components through heat conduction inside the body. At the same time, due to the compact internal structure of the body and the lack of a high thermal conductivity heat dissipation path, this part of the leaked heat increases the overall temperature of the body, but it cannot be well conducted to the normal temperature environment. As the heating progresses, the heat will continue to accumulate over time, causing the temperature of the outer surface of the body to be too high under certain conditions, thereby affecting the safety of the equipment and user experience.

[0093] In response to one or more of the above-mentioned problems, the embodiments of the present application creatively propose a new aerosol supply device, which is provided with a first gap between the outer shell and the thermal insulation structure, and the first gap is connected to the external environment, so that after the thermal insulation structure receives the heat from the heating leakage, the air in the first gap is heated due to the heat conduction effect to increase its temperature, resulting in natural heat convection between the air in the first gap and the cold air of the external environment, and the heat is quickly exchanged to the external atmosphere through fluid convection, so that the device can obtain efficient heat dissipation and avoid excessive temperature of the outer shell.

[0094] It should be noted that the aerosol supply device provided in the embodiment of the present application does not specifically limit the heating method it adopts, which includes but is not limited to the following methods: central needle heating (such as resistive, inductive, etc.), central sheet heating (such as resistive, inductive, etc.), circumferential heating (such as resistive, inductive, infrared radiation, etc.), mixed heating (such as central / circumferential mixed heating, etc.) and other heating methods (such as air flow heating, etc.).

[0095] The present application scheme is described in detail below using a central needle heating aerosol supply device.

[0096] Embodiment 1

[0097] Figure 1 is a three-dimensional structural schematic diagram of an aerosol supply device and an aerosol product provided in an embodiment of the present application, Figure 2 is a cross-sectional view of an aerosol supply device provided in an embodiment of the present application, Figure 3 is an exploded view of the aerosol supply device provided in the embodiment of the present application, referring to Figures 1 to 3As shown, it generally includes a shell 100, an extractor 200, a heat preservation structure 300, a heating module 400, etc. Among them, a first accommodating chamber 110 is formed inside the shell 100, and the extractor 200, the heat preservation structure 300, the heating module 400 and other components are all accommodated and arranged in the first accommodating chamber 110. A second accommodating chamber 360 is formed inside the heat preservation structure 300, and the second accommodating chamber 360 is used to accommodate the extractor 200. There is a first gap 600 between the shell 100 and the heat preservation structure 300, and the first gap 600 is connected to the external environment. As a result, after the heat preservation structure receives the heat from the heating leakage, the air in the first gap is heated due to the heat conduction effect to increase its temperature, resulting in the formation of natural heat convection between the air in the first gap and the cold air of the external environment, and the heat is quickly exchanged to the external atmosphere through fluid convection, so that the device can be efficiently cooled and the shell temperature is prevented from being too high.

[0098] It should be noted that the embodiment of the present application does not specifically limit the width of the first gap 600. It can be set according to the actual needs of the product without violating the inventive concept of the present application. As an exemplary and non-restrictive explanation, in the embodiment of the present application, the width of the first gap 600 is any value between 0.2-1.5mm. For example, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, etc., which are not listed here one by one.

[0099] Further references Figure 1 As shown, in some specific embodiments, the first gap 600 has a first opening 610 at one end of the device in the longitudinal direction, and the first gap 600 is connected to the external environment through the first opening 610. It can be understood that in the embodiment of the present application, the specific position of the first opening 610 is not limited, as long as it can connect the first gap 600 to the external environment. As an exemplary and non-restrictive description, the first opening 610 is set at the end of the first gap 600 facing the user.

[0100] Further references Figure 1 and Figure 2 As shown, as a preferred implementation, in the embodiment of the present application, a vent hole 120 is provided on the outer wall of the shell 100, and the vent hole 120 penetrates the outer wall of the shell 100 in the transverse direction of the device, so that the vent hole 120 can connect the first gap 600 with the external environment.

[0101] In the embodiment of the present application, the number and size of the vent holes 120 are not limited, and can be set according to actual needs without violating the inventive concept of the present application. It can be understood that the more the number and / or the larger the size of the vent holes 120, the more conducive it is to the natural heat convection between the air in the first gap 600 and the cold air in the external environment, that is, the more conducive it is to heat dissipation. Based on this, in some specific embodiments, there are multiple vent holes 120 and they are spaced apart and distributed on the outer peripheral wall of the housing 100.

[0102] In the embodiment of the present application, the arrangement of the vent holes 120 on the outer peripheral wall of the housing 100 is also not specifically limited. In some specific embodiments, there are multiple vent holes 120 and they are distributed on the outer peripheral wall of the housing 100 at intervals along the longitudinal direction of the device; in other specific embodiments, there are multiple vent holes 120 and they are distributed on the outer peripheral wall of the housing 100 at intervals along the circumferential direction of the device. In other specific embodiments, the outer peripheral wall of the housing 100 is a hollow structure, that is, the multiple vent holes opened on the outer peripheral wall of the housing 100 form a hollow structure on the outer peripheral wall of the housing 100, and the first gap 600 is connected to the external environment through the hollow structure, so that the first gap 600 and the external environment can exchange gas through the hollow structure.

[0103] It should be noted that in the embodiments of the present application, the size of the vent holes 120 is not specifically limited, and can be set according to actual product requirements without violating the inventive concept of the present application. In some specific embodiments, different vent holes 120 can be set to have the same size; in other specific embodiments, different vent holes 120 can be set to have different sizes; in other specific embodiments, some vent holes 120 can be set to have the same size, and some vent holes 120 can be set to have different sizes.

[0104] In some specific embodiments, the outer peripheral wall of the housing 100 may be subjected to at least one of the following treatments: a smooth surface, a frosted surface, an anodized surface, a brushed surface, a coated surface, and an electroplated surface.

[0105] In some specific embodiments, in addition to providing a certain number of ventilation holes 120 on the outer peripheral wall of the housing 100, some other structures may also be provided, such as a certain number of countersunk holes, protrusions, positive text, negative text, etc., which are not listed here one by one.

[0106] It is understandable that the embodiment of the present application does not specifically limit the geometric shape of the housing 100, and any housing arranged parallel to the axis of the aerosol product should be considered within the scope of the present design. For example, the cross-sectional shape of the housing 100 along the axis perpendicular to the aerosol product can be divided into a circular cross-section, an elliptical cross-section, a polygonal cross-section, an irregular straight cross-section, an irregular curved cross-section, a cross-section variable along the axis, and the like.

[0107] In some specific embodiments, the assembly form of the shell 100 and the device can adopt at least one of the following methods: snap fixation, slide groove fixation, threaded fastener fixation, shell self-thread fixation, interference fit fixation, magnetic attraction fixation, top block fixation, adhesive fixation, etc.

[0108] Further references Figure 3 and Figure 4 As shown, the difference from the extractor of the conventional centrally heated aerosol supply device is that the air intake method in the extractor 200 in the embodiment of the present application is a bottom-up design, and the external gas enters the third accommodating chamber 210 for inserting the aerosol product 500 from the bottom of the extractor 200. In specific implementation, the extractor 200 has a first end 260 and a second end 270 in the length direction, and the first end 260 and the second end 270 are opposite ends of the extractor 200 in the length direction. The extractor 200 is provided with a second opening 220 at the first end 260 that is connected to the internal space of the third accommodating chamber 210, and the extractor 200 is provided with an air intake structure 230 at the second end 270. Due to the adoption of the bottom-up airway design, there is no need to set a groove / convex ridge structure for accommodating air flow on the wall surface of the extractor 200, so that the inner and outer wall surfaces of the extractor 200 can be set to a simple and smooth standard cylindrical shape.

[0109] It is understood that the aerosol product 500 includes various rod-shaped or strip-shaped structures for inserting into the extractor 200 and being heated and atomized to generate aerosol, such as those containing tobacco, those containing no tobacco but containing nicotine, and those containing no tobacco and no nicotine, etc., which are not listed here one by one. The aerosol product 500 includes an aerosol generating substrate, which can generate aerosol after being heated and atomized by the heating module 400.

[0110] It is understandable that the extractor 200 is configured to adopt a bottom-up airway design so that the airflow therein flows from bottom to top. According to the principles of thermodynamics, under a certain pressure, the density of hot air is slightly smaller than the density of cold air. Therefore, in the absence of severe external disturbances, if there is a temperature difference in the air flow field, the hot air flow will tend to move upward and the cold air flow will tend to move downward. Under most normal working conditions of the aerosol supply device, the aerosol product, that is, the heat source, is always located at the upper end relative to the cold air in the initial section of the air inlet. This means that the hot air in the third accommodating chamber 210 or at the end of the airway will not spontaneously flow out of the air inlet from the end of the air inlet like the hot air in the top-down air inlet, resulting in a continuous loss of heat energy.

[0111] As a preferred implementation, in the embodiment of the present application, the diameter of the inner wall of the extractor 200 (i.e., the diameter of the third accommodating chamber 210) is set to be slightly smaller than the diameter of the heated aerosol product. As a result, a slight interference fit will be generated after the aerosol product is placed in, so that the aerosol product and the inner wall of the third accommodating chamber 210 are fully fitted together, avoiding the existence of gaps that cause air to be trapped. At the same time, the smooth outer wall of the extractor 200 can be fully fitted with the inner wall of the insulation structure 300, thereby improving the overall control ability of the extractor 200 and the insulation structure 300 over heat leakage, thereby improving the thermal insulation effect of the aerosol product. In addition, the smooth inner and outer walls of the extractor 200 also help to improve the ease of cleaning and production processability of the extractor 200.

[0112] It is understandable that a gap as small as possible can be reserved between the heat preservation structure 300 and the extractor 200 for taking out and putting in the extractor. Therefore, the heat preservation structure 300 and the extractor 200 can be considered to be closely matched, so that the heat preservation structure 300 can provide a compact heat preservation space for the aerosol product 500 and the extractor 200 at the axial position, reducing heat accumulation and heat leakage caused by redundant structures.

[0113] Further references Figure 4 As shown, the air intake structure 230 includes a through hole 231, a second gap 232, an auxiliary air channel 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 side wall, and the through hole 231 is arranged on the end face 271 and penetrates the end face 271, so as to connect the internal space of the third accommodating chamber 210 with the external environment; the above-mentioned second gap 232 is formed between the outer peripheral edge of the end face 271 and the circumferential side wall, and the second gap 232 also connects the internal space of the third accommodating chamber 210 with the external environment. The protrusion 234 is arranged on the outer peripheral edge of the end face 271, and one end of the protrusion 234 is connected to the outer peripheral edge of the end face 271, and the other end is connected to the circumferential side wall of the extractor 200. There are a plurality of protrusions 234 and they are arranged at intervals along the circumferential edge of the outer peripheral edge of the end face 271, and the second gap 232 is formed between adjacent protrusions 234. The auxiliary air channel 233 extends radially along the bottom wall of the third accommodating chamber 210 on the protrusion 234, and one end of the auxiliary air channel 233 is connected to the through hole 231, and the other end is connected to the external environment. In this way, the air intake structure 230 has the characteristics of compact structure, high air intake efficiency, excellent support effect, and less heat loss in the air intake channel.

[0114] It can be understood that the second gap 232 includes a plurality of second gaps 232 , and the plurality of second gaps 232 are arranged at intervals along the circumference of the extractor 200 between the outer peripheral edge of the end surface 271 and the circumferential side wall of the extractor 200 .

[0115] Reference Figure 5As shown, the extractor 200 also includes a concave-convex structure 240 arranged on the bottom wall of the internal space of the third accommodating chamber 210. In specific implementation, the concave-convex structure 240 includes a recessed portion 241 and a convex portion 242 arranged at intervals, the recessed portion 241 is connected to the second gap 232, and the convex portion 242 abuts against the aerosol product. Such a configuration can, on the one hand, reduce the retention of substances such as ash and condensate in the internal space of the third accommodating chamber 210 (i.e., the heating chamber) during use, and on the other hand, when the user takes the extractor 200 out of the device after inhalation, the aerosol product can obtain a uniform supporting force on the entire bottom of the internal space of the third accommodating chamber 210, thereby minimizing the residue of the aerosol generating matrix on the heating needle and the shedding of the aerosol generating matrix in the extractor.

[0116] In some specific embodiments, the recessed portion 241 and the raised portion 242 each include a plurality of recessed portions 241 and a plurality of raised portions 242 , and the plurality of recessed portions 241 and the plurality of raised portions 242 are arranged at intervals. Each recessed portion 241 is connected to at least one second gap 232 .

[0117] 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 , so that the air of the external environment can enter the third accommodating chamber 210 through the first gap 600 and the air intake structure 230 in sequence.

[0118] Further references Figure 3 and Figure 4 As shown, as a preferred embodiment, in the embodiment of the present application, the extractor 200 further includes a gripping ring 250. The gripping ring 250 extends radially outward along the third accommodating cavity 210 at the second opening 220. Preferably, the diameter of the gripping ring 250 is set to be larger than the diameter of the third accommodating cavity 210, and the thickness of the gripping ring 250 is set to be larger than the thickness of the side wall of the third accommodating cavity 210. It can be understood that the gripping ring 250 with a large diameter and a large thickness can improve the structural rigidity of the entire extractor 200, especially the top gripping part, so that when the user holds the extractor 200 with force, or when the extractor 200 falls and collides with the device as a whole, the self-deformation is reduced, and the stability and integrity of the overall structure are maintained.

[0119] In some specific embodiments, a weight-reducing groove 251 is provided on the surface of the side of the holding ring 250 facing the air intake structure 230. The provision of the weight-reducing groove 251 can reduce the structural weight of the holding ring 250 while ensuring its high strength and high rigidity. At the same time, the presence of the holding ring 250 significantly reduces the cross-sectional area (heat conduction area) of the holding ring 250 in all directions, thereby reducing the diffusion rate of the high temperature in the center of the extractor to the holding ring 250, thereby reducing the user's contact-perceived temperature of the holding ring 250 after the heating cycle. It should be noted that the shape and size of the weight-reducing groove 251 are not specifically limited in the embodiment of the present application, and can be set according to actual product requirements without violating the inventive concept of the present application.

[0120] As a preferred embodiment, in the embodiment of the present application, the extractor 200 is provided with one end of the holding ring 250 which is clamped on the housing 100. Specifically, the extractor 200 is clamped on the housing 100 through the holding ring 250. The heat preservation structure 300 is sleeved on the outside of the extractor. In some specific embodiments, the heat preservation structure 300 and the second rib 900 on the base 800 are interference fit, so that the heat preservation structure 300 and the housing 100 are not in contact, thereby reducing the heat transferred to the housing 100 through the heat preservation structure 300. In other specific embodiments, the heat preservation structure 300 can be connected to the housing by means of buckles, etc., so that there is only a little contact between the heat preservation structure 300 and the housing 100, thereby reducing the heat transferred to the housing 100 through the heat preservation structure 300.

[0121] Further references Figure 3 As shown, the heat preservation structure 300 includes an inner shell 310, an outer shell 320 and a filling layer 330. The inner shell 310 and the outer shell 320 cooperate to form a hollow structure, and the filling layer 330 is arranged in the hollow structure. It should be noted that in the embodiment of the present application, the assembly method between the inner shell 310 and the outer shell 320 is not specifically limited, and can be set according to actual product requirements without violating the inventive concept of the present application. For example, in some specific embodiments, the inner shell 310 and the outer shell 320 are integrally formed and a hollow structure is formed between the two.

[0122] In some specific embodiments, the inner shell 310 and / or the outer shell 320 are plastic layers. It is understandable that the inner shell 310 and the outer shell 320 are both made of high temperature resistant plastic materials, such as polyetheretherketone (PEEK), etc., which is not specifically limited here.

[0123] In some specific embodiments, the filling layer 330 is an aerogel thermal insulation material, such as silica aerogel, etc., which is also not specifically limited here.

[0124] As a preferred implementation, in the embodiment of the present 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 are not listed here one by one. Further 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 the conventional design (usually 0.5 to 1.0 mm), so the thermal insulation effect will be better.

[0125] Further references Figure 3 As shown, as a preferred embodiment, in the embodiment of the present application, the thermal insulation structure 300 also includes a positioning block 340 and a buckle 350 arranged on the outer side wall of the outer shell 320. The positioning block 340 is in surface contact with the outer shell 100, thereby ensuring the coaxiality between the thermal insulation structure 300 and the axis of the aerosol product. The buckle 350 cooperates with the pre-set groove on the outer shell 100 to form a buckle fixation, which fixes the position of the thermal insulation structure 300 in the device. At the same time, it also makes it possible for the thermal insulation structure 300 with its own integrated design to be easily removed from the device when necessary, without affecting other fasteners of the device during removal, thereby improving the cleaning efficiency.

[0126] It is understandable that, through the above arrangement, the contact surface of the thermal insulation structure 300 with other parts of the device can be only the small contact surface of the positioning block 340 and the buckle 350 with the shell 100 and the small contact surface of the first rib on the bottom wall when it is fixed. The sum of the above contact surface areas is a very small proportion compared to the total surface area of ​​the thermal insulation structure 300, thereby forming a fixing method that can be compared to a suspended type. This arrangement, on the one hand, can control the heat conducted through the direct contact between the thermal insulation structure 300 and other parts of the device within a very small range, and then when the thermal insulation structure 300 is heated and heated under working conditions, a large part of the heat will be trapped in the thermal insulation layer itself, and will not be quickly transferred out. In layman's terms, even if the temperature of the thermal insulation structure 300 itself rises significantly, there is no way to drive the surrounding parts to heat up quickly with it. On the other hand, the thermal insulation structure 300 still has a part of heat diffusion to the outside. However, in the above design, this part of heat can only be transmitted through infrared heat radiation and convection with the external air. With the assistance of the specially designed shell 100, these two heat transfer methods will not cause rapid heating of the shell 100 and other components, nor will they significantly increase the contact perceived temperature when the user holds the body.

[0127] It should be noted that the present application does not specifically limit the number of positioning blocks 340 and buckles 350, and can be set according to actual product requirements without violating the inventive concept of the present application. As an exemplary and non-restrictive description, the positioning blocks 340 and buckles 350 in the embodiment of the present application include multiple positioning blocks 340 and buckles 350, and the multiple positioning blocks 340 and buckles 350 are spaced apart on the outer side wall of the outer shell 320 along the circumference of the thermal insulation structure 300.

[0128] As a preferred embodiment, in the embodiment of the present application, the size of the filling layer 330 in the longitudinal direction of the heat preservation structure 300 exceeds the top of the region corresponding to the aerosol generating matrix of the aerosol product and at least exceeds the bottom of the above region. Preferably, the size of the filling layer 330 in the longitudinal direction of the heat preservation structure 300 may exceed the top of the region corresponding to the aerosol generating matrix of the aerosol product by at least 10 mm, and may exceed the above bottom by at least 5 mm. It can be understood that the heating module 400 of the aerosol supply device of the central needle heating method generally includes a heating needle 410, which is used to be inserted into the aerosol generating matrix of the aerosol product 500 to heat it to generate an aerosol. The size of the filling layer 330 in the longitudinal direction of the heat preservation structure 300 exceeds the top of the heating needle 410, preferably, it may exceed at least 10 mm, and at least exceeds the bottom of the heating needle 410, preferably, it may exceed at least 5 mm, so that the wrapping of the filling layer 330 in the length direction of the device is also far beyond the conventional design, further improving the heat preservation effect.

[0129] Reference Figure 6 As shown, as a preferred embodiment, in the embodiment of the present application, there is a third gap 1100 between the bottom of the heat preservation structure 300 and the bottom wall of the first accommodating chamber 110, and the third gap 1100 is connected to the air intake structure 230. It can be understood that in the embodiment of the present application, the third gap 1100 is arranged to be connected to the first gap 600, so that the air intake structure 230 is connected to the first gap 600 through the third gap 1100, and thus connected to the external environment, so that the air of the external environment can enter the third gap 1100 through the first gap 600, and then enter the air intake structure 230 through the third gap 1100, and then enter the internal space of the third accommodating chamber 210 through the air intake structure 230.

[0130] Reference Figure 7 As shown, in some specific embodiments, the bottom of the thermal insulation structure 300 and the bottom wall of the first accommodating cavity 110 are provided with a first rib 700, and the first rib 700 extends along the longitudinal direction of the device on the bottom wall of the first accommodating cavity 110 so that the above-mentioned third gap 1100 is formed between the bottom of the thermal insulation structure 300 and the bottom wall of the first accommodating cavity 110.

[0131] It can be understood that since the bottom of the insulation structure 300 is in contact with the first rib 700 on the bottom wall of the first accommodating 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 accommodating cavity 110, so that the heat conducted through the direct contact between the insulation structure 300 and other components of the device can be controlled within a very small range. When the insulation structure 300 is heated under working conditions, a large part of the heat will be trapped in the insulation layer itself and will not be quickly transferred out.

[0132] It should be noted that, in the embodiment of the present application, the number of the first ribs 700 is not specifically limited, and can be set according to actual product requirements without violating the inventive concept of the present application. As an exemplary and non-restrictive description, the first ribs 700 in the embodiment of the present application include a plurality of first ribs 700, which are spaced apart on the bottom wall of the first accommodating cavity 110 along the circumference of the thermal insulation structure 300, and the third gap 1100 is formed between adjacent first ribs 700.

[0133] Further references Figure 2 , Figure 3 and Figure 7 As shown, as a preferred embodiment, in the embodiment of the present application, the device further includes a base 800, which is arranged at the bottom of the first accommodating chamber 110. On the one hand, the bottom end of the extractor 200 is supported on the top surface of the base 800, and on the other hand, the heat preservation 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 preservation structure 300 and the outer peripheral wall of the base 800, and the fourth gap 1200 is connected with the third gap 1100, so that the fourth gap 1200 is connected with the external environment. It can be understood that in the embodiment of the present application, the fourth gap 1200 is arranged to be connected with the air intake structure 230, so that the air intake structure 230 is connected with the external environment through the fourth gap 1200, the third gap 1100, and the first gap 600 in sequence, so that the air of the external environment can enter the air intake structure 230 after passing through the first gap 600, the third gap 1100, and the fourth gap 1200 in sequence, and then enter the internal space of the third accommodating chamber 210 through the air intake structure 230.

[0134] Further references 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 heat preservation structure 300, and the second rib 900 extends along the length direction of the device so that the fourth gap 1200 is formed between the inner wall of the heat preservation structure 300 and the outer peripheral wall of the base 800. It should be noted that in the embodiment of the present application, the number of the second ribs 900 is not specifically limited, and can be set according to actual product requirements without violating the inventive concept of the present application. As an exemplary and non-restrictive explanation, the second rib 900 in the embodiment of the present application includes a plurality of second ribs 900, and the plurality of second ribs 900 are arranged at intervals on the outer peripheral wall of the base 800 along the circumference of the base 800, and the fourth gap 1200 is formed between adjacent second ribs 900.

[0135] In some specific embodiments, a light ring 1400 is provided between the base 800 and the bottom of the first accommodating cavity 110. Furthermore, the light ring 1100 is provided near the air intake structure 230, so that the air intake structure 230 can also serve as a light inlet, and thus, even when the extractor 200 is placed in the shell, the light ring 1100 can provide lighting to the inside of the extractor 200. Preferably, the circular surface of the light ring 1100 is arranged parallel to the lower end surface of the extractor 200. A plurality of different lighting effect zones are provided on the device. When the installation status of the extractor 200 is different, the light ring 1100 will illuminate different lighting effect zones, so that the user can conveniently and intuitively check the status of the internal area of ​​the aerosol supply device at any time, so as to timely eliminate abnormal conditions such as foreign matter or cigarette residues in the cavity.

[0136] It should be noted here that the specific setting form of the lighting effect zone is not limited in the embodiment of the present application. Under the premise of not violating the inventive concept of the present application, the user can set it according to actual product needs.

[0137] It is understandable that in some preferred embodiments, some buttons may be provided on the device to control the opening or closing of the light ring 1100. In some specific embodiments, the buttons may be a combination of one or more of mechanical rebound buttons, capacitive touch buttons, capacitive touch and vibration feedback buttons, etc. In other specific embodiments, the buttons may also be a combination of one or more of mechanical knobs, mechanical rollers, electromagnetic rollers, etc., which are not specifically limited here.

[0138] In some specific embodiments, the base 800 may be made of high temperature resistant PEEK plastic, which is not specifically limited in the present application.

[0140] Further references Figure 3 As shown, in some specific embodiments, a spacer 1000 is provided between the shell 100 and the heat preservation structure 300, so that the above-mentioned first gap 600 is formed between the shell 100 and the heat preservation structure 300. It should be noted that in the embodiment of the present application, the setting position, shape and size of the spacer 1000 are not specifically limited, and can be set according to actual product requirements without violating the inventive concept of the present application. In some specific embodiments, the spacer 1000 can be provided on the inner wall of the shell 100 or integrally formed with the inner wall of the shell 100; in other specific embodiments, the spacer 1000 can be provided on the outer wall of the heat preservation structure 300 or integrally formed with the outer wall of the heat preservation structure 300.

[0141] As a preferred implementation manner, in the embodiment of the present application, the spacer 1000 can be integrally formed with the positioning block 340, that is, the positioning block 340 is used 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.

[0142] Further references Figure 2 and Figure 3 As shown, as a preferred implementation, in the embodiment of the present application, the heating module 400 includes a heating needle 410, a thermal insulation base 420 and a thermal insulation layer 430. The heating needle 410 is arranged at the center of the end of the thermal insulation base 420 facing the extractor 200, the base 800 is arranged outside the thermal insulation base 420, and the thermal insulation layer 430 is filled between the base 800 and the thermal insulation base 420. The thermal insulation layer 430 can be made of aerogel thermal insulation material. The setting of the thermal insulation layer 430 can greatly reduce the diffusion ability of a small part of the heat that freely roams in the air inlet to the side wall of the air inlet.

[0143] It can be understood that, for the fourth gap 1200 along the transverse cross-section of the device, its outer ring is surrounded by the insulation structure 300, and the inner ring is also surrounded by the insulation layer 430. Therefore, both sides of the higher temperature air in the fourth gap 1200 are surrounded by insulation materials, which greatly reduces the rate of heat transfer to the outside through the higher temperature air in the fourth gap 1200, thereby improving the overall insulation efficiency of the system.

[0144] It should be noted that the embodiment of the present application does not specifically limit the thermal insulation base 420 and can be configured according to actual needs without violating the inventive concept of the present application. For example, the thermal insulation base 420 can be a ceramic base.

[0145] In summary, through the scheme provided by the embodiment of the present application, during the heating process of the device, although the heat leaked from the insulation structure 300 will cause the overall temperature of the insulation structure 300 to gradually increase with the progress of heating, this part of the leaked heat will not be like the conventional aerosol supply device, and can only be gradually diffused through the mutual heat conduction of the structure in the device. After causing the overall temperature of the device to rise significantly, the device outer surface will contact the air to achieve low-rate heat dissipation and cooling. In contrast, in the aerosol supply device provided by the embodiment of the present application, when the insulation structure 300 receives the heat from the heating leakage, its own temperature will rise to above the ambient atmospheric temperature. At the same time, the air in the first gap 600 is always connected to the atmosphere (under ideal conditions, before the device starts working, the air pressure and temperature in the first gap 600 are the same as the ambient atmosphere). The lower temperature air in the first gap 600 contacts the higher temperature insulation structure 300, and an initial heat conduction effect is generated due to the temperature difference, resulting in the air near the boundary of the insulation structure 300 being heated and the temperature rising. Afterwards, the hot air near the boundary of the thermal insulation structure 300 will have a temperature difference with the air in the outer layer of the first gap 600. Driven by the fluid-fluid temperature field difference, the air in the first gap 600 will produce a natural thermal convection effect, causing the air in the flow field to quickly exchange position, velocity / momentum and heat in the form of vortices, so that the heat is quickly diffused from the thermal insulation structure 300 to the entire air flow layer in the first gap 600.

[0146] Furthermore, since the air in the first gap 600 is connected to the outside world, the air in the first gap 600 heated by the above process will continue to form natural heat convection with the cold air outside through a large number of through holes on the shell 100, and quickly exchange heat to the outside atmosphere through fluid convection. As a result, the colder air outside will be exchanged into the first gap 600 by the convection effect, replacing its own air, and undergoing a new round of heat exchange with the insulation structure 300. During this entire process, the insulation structure 300 is able to continuously contact the relatively low-temperature air for efficient heat dissipation, avoiding the problem of a decrease in the temperature difference between the air layer and the insulation structure 300 and a decrease in heat transfer capacity due to a substantial increase in the temperature of the air layer. The flowing air layer in the first gap 600 layer can thus form a dynamic balance of heat under the action of fluid heat transfer, maintaining a temperature significantly lower than the surface temperature of the insulation structure 300.

[0147] Furthermore, since the housing 100 is made of a highly thermally conductive material and has a large number of through holes thereon, there is a large amount of actual surface contact area between the housing 100 and the air layer exchanged by convection. Therefore, while the air in the first gap 600 is convectively exchanged with the outside world, the solid-fluid two-phase contact between the hotter air and the colder shell will also bring about a considerable heat conduction effect, so that the housing 100 actually plays the role of a "heat sink fin" and transfers part of the heat in the hot air to the housing 100. Since there is not much direct contact between the housing 100 and the insulation structure 300, the solid-solid heat conduction effect is extremely limited and can be approximately ignored. Therefore, only the above-mentioned part of the heat transferred to the housing 100 through air heat transfer is generally limited in rate and value. In addition, the structure and material design of the housing 100 itself are also conducive to heat diffusion. The comprehensive result is that under this design, the surface temperature of the housing 100 is greatly reduced compared with the insulation structure 300, and the thermal decoupling of the device housing 100 and the heat source is achieved to a large extent, significantly improving the thermal management capability of the device.

[0148] It can be understood that since the heat dissipation effect of the aerosol supply device provided in the embodiment of the present application strongly depends on the convective heat dissipation effect brought by the open air layer, the heat dissipation / surface cooling capacity of the system is further improved under the following two conditions compared with the standard test conditions:

[0149] 1. In certain circumstances, when the temperature difference between the ambient atmosphere and the center of the heating needle of the device is greater (such as the ambient temperature is colder than that in the standard test, or the heating power curve is artificially adjusted higher), the temperature difference between the insulation structure 300 and the ambient atmosphere is also greater during the operation of the device, which will bring about a stronger natural heat convection effect of the air. As a result, under the above-mentioned specific circumstances, the temperature difference between the insulation structure 300 / atmosphere and the temperature difference between the shell 100 / insulation structure 300 are not proportional under the working conditions of the device. For example, when the atmospheric temperature is stable at 25°C room temperature, and other conditions remain unchanged, the high and low heating powers are artificially controlled for testing. At low power, the maximum temperature of the insulation structure 300 in the test is 45°C, and the maximum temperature of the shell 100 is 30°C; when at high power, the maximum temperature of the insulation structure 300 is 70°C, and the maximum temperature of the shell 100 is 40°C. In other words, when the temperature difference between the insulation structure 300 / atmosphere rises by 25°C, the temperature difference between the shell 100 / insulation structure 300 only rises by 10 degrees.

[0150] 2. When there is air flow in the use environment that is unrelated to the device itself (such as natural wind in the open air environment, forced air flow caused by air conditioning, etc.), the external air flow will cooperate with the natural heat convection of the device itself, intensifying the fluid convection heat dissipation effect under this design.

[0151] It should be noted that the aerosol supply device provided in the embodiment of the present application includes, in addition to the components described above, a body 1600, and the components described above are all assembled on the body 1600.
