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] Since the heat-not-burn aerosol supply device needs to heat the cigarette to a certain high temperature during operation, in order to prevent the heat from overflowing during this process and causing the temperature of the various structures of the body to exceed the acceptable range, certain measures need to be taken to control the high temperature diffusion from the heating cavity to the outside. The existing conventional design is to attach a circle of aerogel insulation material along the outer wall of the heating cavity in an annular manner, and achieve a certain degree of heat insulation by utilizing the high thermal resistance of the aerogel material.

[0003] However, the conventional heat insulation design in the existing heat-not-burn aerosol supply device usually has the following disadvantages:

[0004] 1. Under the existing design, due to the limited space and structure inside the device, the surface area of ​​the cavity protected by the aerogel layer on the outer wall of the heating cavity is too small, resulting in limited thermal insulation effect. The specific reasons are as follows:

[0005] 1) Since the heating cavity is arranged inside the device, it needs to contact or cooperate with many other structures of the device to achieve fixation. At the same time, structural adaptation and compromise may also be required due to the spatial layout of the device. The above two points will bring various additional mechanical structures, resulting in too small a flat surface area on the outer wall of the heating cavity that can be used to arrange the aerogel layer. This directly leads to limited insulation effect of the heating cavity, and it is difficult to increase the upper limit of the insulation capacity of the body by increasing the aerogel surface area, which is the most direct and effective measure.

[0006] 2) Based on the same reasons as in 1), the heating cavity fixed inside the device often has very dense mating surfaces and contact surfaces with other parts of the device. This results in a large solid-solid heat conduction cross-sectional area and a complex heat conduction path between the structures. When part of the heat is isolated by the aerogel layer and cannot diffuse outward quickly along the normal direction of the wall, it will accumulate on the heating cavity; at the same time, the structure near the heating cavity that is not well protected by the aerogel will also cause considerable heat leakage due to the low thermal resistance. Under the combined effect of the above two parts of heat, the temperature of the heating cavity structure increases significantly. The heated structure will continue to diffuse the heat outward through the above-mentioned contact surface / mating surface with other components through heat conduction, causing the body temperature to increase significantly.

[0007] 2. The poor thermal insulation capacity under conventional design causes considerable heat leakage, which not only makes it difficult to control the overall temperature of the device, but also requires the heating needle or heating tube to consume more energy to compensate for the heat leakage in the device when the cigarette is maintained at a certain temperature-time curve. Furthermore, under a certain battery capacity, heat leakage will directly affect the battery life of the aerosol supply device.

[0008] 3. In the current cigarette extractors that use aerosol supply devices with central heating needles, a common way of air intake is the inflow of air from top to bottom. To achieve this function, the side walls of the extractor are arranged with varying numbers of grooves / convex grooves along the circumference of the axis, so that a certain gap is left between the matching surfaces of the cigarette and the extractor to form a flow channel, so that air can flow into the cigarette through this gap to complete the air intake process. This gap is arranged between the cigarette and the aerogel insulation layer and is not within the isolation range of the aerogel. Therefore, part of the heat will be transferred to this gap through the high-temperature cigarette, and then come into contact with the cold air from the outside along the gap and quickly dissipate. This type of air intake structure actually weakens the insulation effect of the cigarette and also causes unnecessary heat waste.

[0009] 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

[0092] 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.

In this article, a device configured to generate a varying magnetic field is referred to as a magnetic field generator.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] As described in the background technology, the existing heat-not-burn aerosol supply device is limited by the space and structure inside the device, and the surface area of ​​the cavity protected by the aerogel layer on the outer wall of the heating cavity is too small, resulting in limited thermal insulation effect. In addition, the heat leakage caused by poor thermal insulation will directly affect the battery life of the aerosol supply device.

[0099] 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 an insulation structure at least on the periphery of the extractor or the heating tube, and the insulation structure completely covers the outer surface of the preset area accommodating the aerosol generating matrix, so that the closed coverage area of ​​the heat source by the insulation structure is greatly increased, thereby improving the thermal insulation effect, reducing heat energy loss, and improving the power utilization efficiency of the device.

[0100] 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.).

[0101] The present application scheme is described in detail below using a central needle heating aerosol supply device.

[0102] Embodiment 1

[0103] 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 housing 100, an extractor 200, a heat preservation structure 300, a heating module 400, etc. Among them, a housing 110 is formed inside the housing 100, and the extractor 200, the heat preservation structure 300, the heating module 400 and other components are all accommodated and arranged in the housing 110. The extractor 200 has a columnar structure 210, and the columnar structure 210 is a hollow structure, and an internal space is formed therein for the aerosol product 500 to be inserted. It can be understood that the aerosol product 500 includes various rod-shaped or strip-shaped structures for inserting the extractor 200 and being heated and atomized to generate aerosols, 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 one by one here. The aerosol product 500 includes an aerosol generating substrate, and the aerosol generating substrate can generate an aerosol for the user to inhale after being heated and atomized by the heating module 400. The columnar structure 210 has a preset area 211, and the preset area 211 is used to accommodate the aerosol generating matrix of the aerosol product. The heat preservation structure 300 is at least arranged on the periphery of the extractor 200, and the heat preservation structure 300 completely covers the outer surface of the preset area 211. By setting the heat preservation structure 300 to completely cover the outer surface of the preset area 211, the closed coverage area of ​​the heat preservation structure 300 to the heat source is greatly increased, thereby improving the heat preservation and heat insulation effect, reducing heat energy loss, and improving the power utilization efficiency of the device.

[0104] It is understandable that the larger the coverage area of ​​the heat preservation structure 300 on the periphery of the extractor 200, the better the heat preservation and heat insulation effect. Therefore, in some specific embodiments, the coverage area of ​​the heat preservation structure 300 on the periphery of the extractor 200 is preferably larger than the outer surface of the preset area 211. Further preferably, the heat preservation structure 300 completely covers the outer surface of the columnar structure 210.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] As a preferred embodiment, in the embodiment of the present application, the thickness of the filling layer 330 is at least 0.1 mm. Preferably, the thickness of the filling layer 330 can be 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. Further preferably, the thickness of the filling layer 330 can be 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 are not listed here one by one. The thickness of the filling layer 330 is set to any value between 1.0 and 1.5 mm. Compared with the conventional design (usually 0.5 to 1.0 mm), its thickness is thicker, so the thermal insulation effect will be better.

[0109] 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.

[0110] 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 with the protrusion 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.

[0111] 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.

[0112] 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 at least exceeds the top of the preset area 211 and at least exceeds the bottom of the preset area 211. Preferably, the size of the filling layer 330 in the longitudinal direction of the heat preservation structure 300 may exceed the top of the preset area 211 by at least 10 mm, and may exceed the bottom of the preset area 211 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 insert 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 at least 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.

[0113] 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 hollow columnar structure 210 for inserting the aerosol product from the bottom of the extractor 200. In specific implementation, the extractor 200 also includes an opening 220 connected to the internal space of the columnar structure 210 and an air intake structure 230 arranged at one end away from the opening 220. Due to the bottom-up airway design, there is no need to set a groove / convex ridge structure on the wall of the extractor 200 for accommodating air flow, so that the inner and outer wall surfaces of the columnar structure 210 of the extractor 200 can be set to a simple and smooth standard cylindrical shape.

[0114] 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 columnar structure 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.

[0115] As a preferred implementation, in the embodiment of the present application, the diameter of the inner wall of the columnar structure 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 columnar structure 210 are fully fitted together, avoiding the presence of gaps that cause air to be trapped. At the same time, the smooth outer wall of the columnar structure 210 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 columnar structure 210 also help to improve the ease of cleaning and production processability of the extractor 200.

[0116] 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.

[0117] Further references Figure 4 As shown, in the embodiment of the present application, the air intake structure 230 includes a first air intake hole 231, a second air intake hole 232, and an auxiliary air duct 233. The first air intake hole 231 is arranged at the center position of the bottom wall of the columnar structure 210, connecting the internal space of the columnar structure 210 with the external environment. The second air intake hole 232 is arranged at the edge position of the bottom wall of the columnar structure 210, and also connects the internal space of the columnar structure 210 with the external environment. The auxiliary air duct 233 extends radially along the bottom wall of the columnar structure 210, and one end of the auxiliary air duct 233 is connected to the first air intake hole 231, and the other end is connected to the external environment. With such a configuration, the air intake structure 230 can have the characteristics of compact structure, high air intake efficiency, excellent supporting effect, and less heat loss in the air intake duct.

[0118] As a preferred implementation, in the embodiment of the present application, the second air inlet holes 232 include a plurality of second air inlet holes 232 , which are arranged at intervals along the circumference of the columnar structure 210 on the edge of the bottom wall of the columnar structure 210 .

[0119] As a preferred implementation, in the embodiment of the present application, the auxiliary air channel 233 includes a plurality of auxiliary air channels 233 , and the plurality of auxiliary air channels 233 are arranged at intervals along the circumference of the columnar structure 210 on the bottom wall of the columnar structure 210 .

[0120] Reference Figure 5 As shown, the extractor 200 also includes a concave-convex structure 240 arranged on the bottom wall of the internal space of the columnar structure 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 air inlet 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 columnar structure 210 (i.e., the heating cavity) 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 columnar structure 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.

[0121] 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 disposed at intervals. Each recessed portion 241 is communicated with at least one second air inlet hole 232 .

[0122] Further references Figure 3 and Figure 4As 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 columnar structure 210 at the opening 220. Preferably, the diameter of the gripping ring 250 is set to be larger than the diameter of the columnar structure 210, and the thickness of the gripping ring 250 is set to be larger than the thickness of the side wall of the columnar structure 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.

[0123] 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.

[0124] As a preferred embodiment, in the embodiment of the present application, one end of the extractor 200 away from the preset area 211 (i.e., the end of the extractor 200 provided with the gripping ring 250) is snap-fitted to the housing 100. Specifically, the extractor 200 is snap-fitted to the housing 100 via the gripping ring 250. The heat-insulating structure 300 is sleeved on the outside of the extractor. In some specific embodiments, the heat-insulating structure 300 and the ribs 900 are interference-fitted, so that the heat-insulating structure 300 and the housing 100 are not in contact, thereby reducing the heat transferred to the housing 100 through the heat-insulating structure 300. In other specific embodiments, the heat-insulating structure 300 can be connected to the housing by means of buckles, etc., so that there is only a little contact between the heat-insulating structure 300 and the housing 100, thereby reducing the heat transferred to the housing 100 through the heat-insulating structure 300.

[0125] Reference Figure 6As shown, as a preferred implementation, in the embodiment of the present application, there is a first gap 610 between the bottom of the heat preservation structure 300 and the bottom wall of the accommodating cavity 110, and the first gap 610 is connected to the external environment. It can be understood that in the embodiment of the present application, the first gap 610 is arranged to be connected to the air intake structure 230, so that the air intake structure 230 is connected to the external environment through the first gap 610, so that the air of the external environment can enter the air intake structure 230 through the first gap 610, and then enter the internal space of the columnar structure 210 through the air intake structure 230.

[0126] Reference Figure 7 As shown, in some specific embodiments, a protrusion 700 is provided on the bottom of the thermal insulation structure 300 and the bottom wall of the accommodating cavity 110, and the protrusion 700 extends along the longitudinal direction of the device on the bottom wall of the accommodating cavity 110 so that the above-mentioned first gap 610 is formed between the bottom of the thermal insulation structure 300 and the bottom wall of the accommodating cavity 110.

[0127] It can be understood that since the bottom of the insulation structure 300 is in contact with the protrusion 700 on the bottom wall of the 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 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. Further, 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.

[0128] It should be noted that in the embodiment of the present application, the number of protrusions 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 protrusions 700 in the embodiment of the present application include multiple protrusions 700, and the multiple protrusions 700 are spaced apart on the bottom wall of the accommodating cavity 110 along the circumference of the thermal insulation structure 300, and the above-mentioned first gap 610 is formed between adjacent protrusions 700.

[0129] Further references Figure 2 , Figure 3 and Figure 7As shown, as a preferred embodiment, in the embodiment of the present application, the device also includes a base 800, and the base 800 is arranged at the bottom of the 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 second gap 620 is formed between the inner wall of the heat preservation structure 300 and the outer peripheral wall of the base 800, and the second gap 620 is connected to the first gap 610, so that the second gap 620 is connected to the external environment. It can be understood that in the embodiment of the present application, the second gap 620 is arranged to be connected to the air intake structure 230, so that the air intake structure 230 is connected to the external environment through the second gap 620 and the first gap 610 in turn, so that the air of the external environment can enter the air intake structure 230 after passing through the first gap 610 and the second gap 620 in turn, and then enter the internal space of the columnar structure 210 through the air intake structure 230.

[0130] Further references Figure 7 As shown, in some specific embodiments, a 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 rib 900 extends along the length direction of the device so that the above-mentioned second gap 620 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 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 rib 900 in the embodiment of the present application includes a plurality of ribs, and the plurality of ribs 900 are arranged at intervals on the outer peripheral wall of the base 800 along the circumference of the base 800, and the above-mentioned second gap 620 is formed between adjacent ribs 900.

[0131] In some specific embodiments, a light ring 1100 is provided between the base 800 and the bottom of the 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] Reference Figure 2 As shown, a third gap 630 is formed between the outer peripheral wall of the heat preservation structure 300 and the housing 100, and the third gap 630 is connected to the first gap 610. It can be understood that in the embodiment of the present application, the third gap 630 is arranged to be connected to the external environment, so that the first gap 610 is connected to the external environment through the third gap 630, so that the air of the external environment can enter the first gap 610 through the third gap 630.

[0136] Further references Figure 1 and Figure 2 As shown, as a preferred implementation, in the embodiment of the present application, the outer peripheral wall of the housing 100 is a hollow structure 120, and the third gap 630 is connected to the external environment through the hollow structure 120, so that the air of the external environment can enter the third gap 630 through the hollow structure 120.

[0137] As a preferred implementation, in the embodiment of the present application, the material of the housing 100 is at least one of metal, polymer, natural or composite materials, which is not specifically limited here and can be set by the user according to actual needs. Among them, metal materials include stainless steel, titanium alloy, aluminum-magnesium alloy, etc., polymer materials include various engineering plastics, PEEK, PC, PP, etc., and natural materials include natural stone, natural crystal, etc., which are not listed here one by one.

[0138] Further references Figure 3As shown, in some specific embodiments, a spacer 1000 is provided between the shell 100 and the heat preservation structure 300, so that the third gap 630 mentioned above 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.

[0139] 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.

[0140] 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.

[0141] It can be understood that, for the second gap 620 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 second gap 620 are surrounded by insulation materials, which greatly reduces the rate of heat transfer to the outside through the higher temperature air in the second gap 620, thereby improving the overall insulation efficiency of the system.

[0142] 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.
