Description

Technical Field

[0001] This invention relates to the field of aerosol heating, and particularly to a housing assembly and an aerosol generating device. Background Technology

[0002] With increasing public awareness of health concerns, people have recognized the health hazards of traditional cigarettes. This has led to the development of products called "heated cigarettes." Compared to traditional cigarettes, heated cigarettes do not burn tobacco, providing users with a pleasant experience while reducing the inhalation of harmful substances. However, heated cigarette devices are small electronic devices, requiring a securely mounted casing. Traditional methods of securing the casing, such as using adhesives or complex connection structures, are cumbersome to manufacture. Furthermore, the casing is easily disassembled, increasing the uncertainty of daily maintenance. User-initiated disassembly can lead to difficulties in repairs when the device needs to be returned to the factory. Repair departments may be unsure whether the damage to the internal casing is due to product defects or user negligence, increasing after-sales difficulty and costs. Summary of the Invention

[0101] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Although the description of the present invention is presented in conjunction with preferred embodiments, this does not mean that the features of the invention are limited to these embodiments. On the contrary, the purpose of describing the invention in conjunction with embodiments is to cover other options or modifications that may be derived based on the claims of the present invention. To provide a deep understanding of the invention, many specific details will be included in the following description. The invention may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of the invention, some specific details will be omitted in the description. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0102] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0103] In the description of this embodiment, it should be noted that the terms "upper," "lower," "higher," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0104] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0105] Furthermore, the directions such as "axial," "circumferential," and "radial" mentioned in this invention are intended to apply to any component in the device of this invention. "Axial" corresponds to the extending direction in the device and its internal components, "circumferential" corresponds to the outer or inner circumferential direction of the device and its internal components, and "radial" is perpendicular to "axial" relative to "axial."

[0106] The "aerosol generating matrix" as used in this invention refers to a matrix capable of releasing volatile compounds that can form aerosols when heated. The aerosol generating matrix of this invention can be solid or liquid. For example, a liquid aerosol generating matrix may contain water, solvents, ethanol, plant extracts, and natural or artificial flavorings. The aerosol generating matrix can also be a paste material, a porous material pouch containing the aerosol generating matrix, or, for example, loose tobacco mixed with a gelling agent or adhesive, which may contain common atomizing agents such as glycerol. Alternatively, the aerosol generating matrix may include tobacco-containing materials or non-tobacco materials, or both, including non-tobacco materials such as flavorings that can be volatilized by heating or not. The aerosol generating matrix also includes atomizing agents such as glycerin or propylene glycol. The aerosol generating matrix may also include additional ingredients such as nicotine or flavoring extracts. For solid aerosol generating matrices, a structure that can be formed into a cartridge or cigarette can be housed in a smoking device, further processed into a heated cigarette, which will also include a tobacco matrix portion and a filter portion.

[0107] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0108] like Figure 1-3As shown, the present invention provides a channel sealing assembly for an aerosol generating device. The aerosol generating device includes a channel with an insertion end, and the channel sealing assembly includes an end plug 1. The channel can be, for example, an air passage or a storage channel. In this embodiment, the channel is, for example, a cigarette bin 2 for storing cigarettes 7. The cigarette bin 2 has an insertion end 21, and the end plug 1 has a front end 11 and a rear end 12. The end plug 1 is inserted into the cigarette bin 2 from its front end 11 through the insertion end 21, and the rear end 12 is positioned outward from the insertion end 21. That is, after the end plug 1 is inserted into place, the rear end 12 is positioned further outward from the cigarette bin 2 than the front end 11. In this embodiment, the direction from the rear end 12 to the front end 11 is consistent with the axial direction of the end plug 1, for example, the axial direction is... Figure 3 The x-direction and axial direction are aligned with the insertion direction of end plug 1. End plug 1 is equipped with a first magnetic body 13, and the channel is equipped with a second magnetic body 22. The first magnetic body 13 and the second magnetic body 22 have the same polarity. During the insertion of end plug 1 into the channel, the first magnetic body 13 moves away from the insertion end 21 and passes over the second magnetic body 22 axially. Therefore, in the initial stage of insertion, end plug 1 experiences a certain repulsive force. As it is inserted deeper, after the first magnetic body 13 passes over the second magnetic body 22 axially, the repulsive force between the first and second magnetic bodies pushes end plug 1 into the channel. When end plug 1 is removed, the channel sealing assembly has an automatic pop-out function.

[0109] Furthermore, between the front end 11 and the rear end 12, a first magnetic body 13 is provided on the end plug 1. Specifically, the first magnetic body 13 is provided on the outer peripheral wall of the end plug 1. The number of first magnetic bodies 13 can be one or more. When there are multiple first magnetic bodies 13, their positions are the same along the axial direction of the end plug 1, that is, the multiple first magnetic bodies 13 do not misalign in the axial direction. It can be understood that when the end plug is cylindrical, the multiple first magnetic bodies 13 are located on the same circumference. A second magnetic body 22 is provided on the inner peripheral wall of the tobacco chamber 2. The second magnetic body 22 can be one or more. When there are multiple second magnetic bodies 22, their positions are the same along the axial direction of the tobacco chamber 2, that is, the multiple second magnetic bodies 22 do not misalign in the axial direction. It can be understood that when the tobacco chamber is cylindrical, the multiple second magnetic bodies 22 are located on the same inner circumference of the tobacco chamber.

[0110] In the above embodiments, the multiple first magnetic bodies have different polarities, and correspondingly, the multiple second magnetic bodies have different polarities, but the polarities of the first magnetic bodies and the corresponding second magnetic bodies in the channel are the same. For example, if there are two first magnetic bodies, namely S-class and N-class, then two second magnetic bodies, namely S-class and N-class, can be set in the channel. The user inserts the end plug in a specific orientation, with the S-class first magnetic body corresponding to the S-class second magnetic body, and the N-class first magnetic body corresponding to the N-class second magnetic body. As the end plug is inserted deeper, it will first be subjected to the repulsive force of being pushed out, and then to the pushing force of being pushed in.

[0111] Preferably, the plurality of first magnetic bodies 13 have the same polarity facing outwards. Since the first magnetic bodies 13 are fixed to the outer wall of the end plug 1, it is sufficient that the first magnetic bodies 13 have the same polarity facing outwards, for example, all of them are S-grade. The plurality of second magnetic bodies 22 have the same polarity relative to each other. Since the second magnetic bodies 22 are fixed to the inner wall of the smoke chamber 2, it is sufficient that they have the same polarity relative to each other, for example, all of them are S-grade. In this embodiment, the first magnetic bodies 13 have the same polarity relative to the second magnetic bodies 22, for example, all of them are S-grade, or all of them are N-grade. In this embodiment, in the axial direction, the distance between the first magnetic body 13 and the rear end 12 is greater than the distance between the second magnetic body 22 and the insertion end 21.

[0112] refer to Figures 4A-4D Through the configuration of the end plug 1 and the structure in the channel in the above embodiments, when the user inserts the end plug 1 into the tobacco chamber 2, because the first magnetic body 13 and the second shape 22 have the same polarity, the end plug will be subjected to such... Figure 4B The magnetic field force pointing to the right, as shown, is opposite to the insertion direction and is a repulsive force. As the first magnetic body 13 gradually approaches the second magnetic body 22, until it passes the second magnetic body 22 and gradually moves away from the insertion end 21, the first magnetic body 13 will experience the following: Figure 4D The magnetic force shown is directed to the left. At this time, the magnetic force is in the same direction as the insertion, and the user will feel a propulsive force to help the end plug 1 be inserted into place.

[0113] refer to Figures 5A-5D When the user removes end plug 1, the first magnetic body 13 on end plug 1 is first subjected to the following: Figure 5A The magnetic field force shown is to the left, opposite to the direction of removal; as the first magnetic body 13 gradually approaches the second magnetic body 22, until the first magnetic body 13 passes the second magnetic body 22 and gradually moves away from the second magnetic body 22 and approaches the insertion end 21, the first magnetic body 13 will be subjected to the following... Figure 5C The magnetic force shown is directed to the right. At this time, the magnetic force is in the same direction as the removal, and the user will feel a propulsive force to facilitate the removal of end plug 1.

[0114] For example, when the second magnetic body 22 is placed on the inner wall of the channel, the distance between the first magnetic body 13 and the rear end 12 is greater than the distance between the second magnetic body 22 and the insertion end 21. After the end plug 1 is inserted into the tobacco chamber 2, the first magnetic body 13 has already passed the second magnetic body 22 and is located further away from the insertion end 21 relative to the second magnetic body 22, that is, it is located further inside the tobacco chamber 2 than the second magnetic body 22. Therefore, after the end plug 1 is inserted into the tobacco chamber, the end plug 1 is always pushed into the tobacco chamber by the second magnetic body 22. This pushing force into the tobacco chamber 2 can be felt by the user when inserting the end plug 1, and it can also keep the end plug 1 inside the tobacco chamber 2 and prevent it from falling off after it is inserted by using magnetic force.

[0115] Furthermore, the outer peripheral wall of the end plug 1 is provided with a first threaded portion 14, and the inner wall of the tobacco chamber 2 is provided with a corresponding engagement portion 23 that engages with the first threaded portion 14. Thus, when the end plug 1 is installed in the tobacco chamber 2, the end plug 1 can be screwed into or out of the tobacco chamber 2 through the threaded connection, thereby achieving a detachable connection.

[0116] Furthermore, in the above embodiment, the first threaded portion 14 is located between the first magnetic body 13 and the rear end 12. After the end plug 1 is partially inserted into the smoke chamber 2, it reaches the starting position where the first threaded portion 14 and the engaging portion 23 engage, and then the user can screw it in to complete the installation of the end plug 1.

[0117] In the above embodiments, the end plug 1 is inserted into the tobacco chamber 2 from its front end 11 through the insertion end 21. As insertion proceeds, the first threaded portion 14 reaches the starting position of the screw-in engagement portion 23. At this time, the first magnetic body 13 is located in the first position axially. The first position is closer to the insertion end 21 than the second magnetic body 22 is closer to the insertion end 21. That is, the first magnetic body 13 is still gradually approaching the second magnetic body 22 and has not yet passed the second magnetic body 22. At this time, the user begins to tighten the screw. When the first threaded portion 14 is fully screwed into the engagement portion 23, that is, when the tightening action is completed, the first magnetic body 13 moves axially to the second position. The second position is farther from the insertion end 21 than the second magnetic body 22 is farther from the insertion end 21, meaning that the first magnetic body 13 has passed the second magnetic body 22. Figure 4D The state in.

[0118] The first and second positions mentioned above represent the positions before and after the first magnetic body 13 and the second magnetic body 22 meet during the insertion of the end plug 1, respectively. During the process of the first magnetic body 13 moving from the first position to the second position, the magnetic force it experiences during insertion changes from resistance to propulsion. The resistance gradually increases, and after the first magnetic body 13 and the second magnetic body 22 meet, it becomes propulsion. During this process, the user completes the process by tightening the thread, so the resistance is not very noticeable, and the screwing process is relatively convenient. After it is fully screwed in, the end plug 1 will be pushed in, and the user will feel the end plug 1 being pushed into place.

[0119] Using the above embodiment, when removing the end plug 1, the user first rotates the end plug to move the first magnetic body 13 from the second position to the first position. During this process, the end plug 1 experiences resistance opposite to the removal direction, and the resistance gradually increases. Only after the first magnetic body 13 and the second magnetic body 22 meet will it become a pushing force for removal. Since the user completes this process through a rotating motion, the resistance is not very noticeable. After the rotation ends, the end plug 1 is now experiencing a pushing force in the same direction as the removal, effectively reminding the user that the rotation is complete and the end plug 1 can be pulled out directly. Simultaneously, the end plug 1 also has an automatic pop-out effect during removal.

[0120] Therefore, the above-described embodiments make it more convenient for users to perform end plug insertion and removal operations.

[0121] In the above embodiment, the pitch of the first threaded portion 14 is greater than or equal to the distance between the first position and the second position. The pitch is the axial distance traveled in one rotation. In this embodiment, the pitch of the first threaded portion 14 is set to be greater than or equal to the distance between the first position and the second position. This allows the user to move the first magnetic body 13 from the first position to the second position with only one or less rotation of the rotating end. This is simpler and more comfortable than rotating several times to complete the movement.

[0122] The specific settings of the first and second positions can be configured according to actual needs, as long as the second magnetic body 22 is located axially between the first and second positions. In this embodiment, the first position can be set as the position where the first magnetic body 13 and the second magnetic body 22 will meet during the insertion of the end plug 1, as shown in the reference. Figure 4B , that is Figure 4B The position where the left end of the first magnetic body 13 connects to the right end of the second magnetic body 22 is defined as the second position where the second magnetic body 13 is about to leave the second magnetic body 22. (Refer to...) Figure 4C That is Figure 4CThe left end of the first magnetic body 13 and the left end of the second magnetic body 22 are completely overlapped radially. That is, in this embodiment, the distance between the first position and the second position is exactly the projected length of the second magnetic body 22 in the axial section. Combining the above embodiment, the thread pitch P can be set to P≥ the projected length of the second magnetic body in the axial section.

[0123] In the above embodiments, even when the threaded connection is loose, the magnetic force still ensures that the end plug 1 is pushed into the smoke chamber 2 and remains in place without detaching. A mechanical locking structure exists between the end plug 1 and the channel, restricting the degree of freedom for the end plug to retract out of the channel. This locking structure is reciprocating and detachable. Furthermore, a non-deformable locking contact form is used to prevent wear and tear after repeated disassembly, which could lead to a decrease in locking performance.

[0124] In the above embodiments, the number of first magnetic bodies can be multiple, preferably 2 to 4, distributed at equal angles along the cross-section. When there are 2 first magnetic bodies, they can be arranged symmetrically on both sides of the end plug. Correspondingly, it is preferable that the number of second magnetic bodies is the same as the number of first magnetic bodies, and their positions and distribution also correspond to those of the first magnetic bodies. The first magnetic bodies can be installed by methods such as snap-fit, tight fit, bonding, or secondary injection molding, and are respectively fastened and assembled onto the end plug. The second magnetic bodies can also be installed in the channel by the above methods to fix them to the channel.

[0125] Preferably, in the above embodiments, the first threaded portion is an external thread, and the engaging portion is an internal thread. Further, the first threaded portion and the engaging portion are double-started or multi-started threads. Even further, the first threaded portion is a partial thread, and the engaging portion is a full thread.

[0126] In the above embodiments, reference is made to Figure 11 An air guide gap 15 is provided between the end plug 1 and the channel. Specifically, for example... Figure 1 At the position indicated in the diagram, a portion of the sidewall of the end plug 1 is shaved off along the axial direction to form a shaved surface 16. Thus, after the end plug 1 is inserted into the tobacco chamber 2, there is an air guide gap 15 between it and the tobacco chamber, so that the airflow can flow through the air guide gap and pass through the entire axial direction of the tobacco chamber 2. Figure 11 The direction indicated by the middle arrow is the flow direction of the airflow through the air guide gap 15. Furthermore, at least a portion of the outer peripheral wall of the end plug 1 forms the aforementioned air guide gap 15, and the remaining portion of the outer peripheral wall is sealed to the smoke chamber 2. For example, in Figure 6, the other circumferential portions besides the air guide gap 15 are sealed, thereby preventing condensate and residues in the smoke chamber 2 from falling out.

[0127] The present invention also provides an aerosol generating device, including a channel sealing assembly of the above embodiments, wherein the channel in the sealing assembly serves as a smoke chamber in the aerosol generating device, capable of containing and heating the aerosol generating matrix. Thus, by providing a removable end plug, the end plug can be removed for cleaning when the smoke chamber needs to be cleaned, and inserted during use to limit the aerosol generating matrix, such as a cigarette, within the smoke chamber.

[0128] Another advantage of the aerosol generating device in the above embodiments is that existing heated smoking appliances require adaptive modifications for cigarettes of different lengths, meaning each appliance must be matched to a specific cigarette length. However, in the above embodiments, the end plug allows for the use of shorter end plugs for longer cigarettes and vice versa, without replacing the entire appliance. Alternatively, in other embodiments, a telescopic end plug can be used instead of replacing the end plug. This allows for adjustment of the end plug's length to accommodate different cigarette lengths, for example, by using a threaded connection or a snap-fit ​​mechanism.

[0129] refer to Figure 7-10 The aerosol generating device of the present invention includes a housing 3 and a smoke chamber 2 located within the housing 3. The smoke chamber 2 is used to contain and heat the aerosol generating matrix and is formed by extending through multiple end joints. The smoke chamber 2 has axial and radial dimensions, for example, axial... Figure 7 In the x-direction, the radial direction is perpendicular to the axial direction, for example... Figure 7 The smoke chamber 2 extends axially and extends through the exterior of the housing 3. Along this axial direction, the radial dimension of the smoke chamber 2 is the same. That is, the entire smoke chamber 2 has no part with a changed inner diameter and extends with a constant diameter in the axial direction.

[0130] In existing technologies, the cigarette compartment is designed with a variable diameter section to limit the movement of the cigarettes contained therein. However, this variable diameter design creates unsanitary corners that are difficult to clean. In this invention, the inner diameter of the cigarette compartment 2 remains constant, and the entire cigarette compartment 2 is straight from top to bottom, connecting to the outside of the housing 3. Correspondingly, an end plug 1 is provided at the bottom to limit the movement of the cigarettes and to properly seal the cigarette compartment 2 to prevent ash and other residues from falling in.

[0131] The smoke chamber 2 is formed by multiple segmented extensions, meaning these segments are independent and disconnected rather than integrally formed. The segments are connected at their ends, and all segments have the same inner diameter, thus not changing the overall inner diameter of the smoke chamber. This multi-segment extension design serves as a heat barrier. In this embodiment, the segments include a heating chamber 24 and an extension chamber 25 with the same inner diameter as the heating chamber. One end of the extension chamber 25 is axially aligned with one end of the heating chamber 24, and the other end of the extension chamber 25 extends directly to the outside of the housing 3.

[0132] By connecting the heating chamber 24 and the extension chamber 25, compared to the integrated heating chamber and extension chamber, the heat transfer from the heating chamber 24 to the extension chamber 25 can be effectively reduced. This avoids overheating of the extension chamber 25 and also reduces heat loss from the heating chamber 24.

[0133] Furthermore, the extension chamber 25 includes an extension pipe 251 and an axially positioned heat insulation pipe 252 between the extension pipe 251 and the heating chamber 24. The two opposite ends of the heat insulation pipe 252 are connected to the heating chamber 24 and the extension pipe 251, respectively. The heating chamber 24, the heat insulation pipe 252, and the extension pipe 251 are connected to form a straight pipe, constituting the smoke chamber 2. The smoke chamber 2 can be cylindrical or prismatic. By connecting the heat insulation pipe 252 and the extension pipe 251, the heat transfer path is interrupted twice again, from the heating chamber 24 to the heat insulation pipe 252 and then to the extension pipe 251, further reducing heat transfer.

[0134] In the above embodiment, the extension tube 251 extends axially to the bottom of the housing 3, thus extending the entire smoke chamber 2 to the bottom of the housing 3. In this way, the entire smoke chamber 2 is completely isolated from other components (such as circuit boards, batteries, etc.) within the housing 3 by its peripheral wall. Therefore, during the use of the aerosol generator, ash, condensate, or tobacco residue formed within the smoke chamber 2 will only fall to the outside of the housing 3 through the bottom of the smoke chamber 2, and will not fall into other components within the housing 3 causing corrosion. The end plug 1 is located at the bottom of the housing 3, inserted through the extension tube 251, and is removable. An air guide gap 15 is provided on the side wall of the end plug 1 between the end plug 1 and the housing 3 and the smoke chamber 2 to allow airflow.

[0135] In the above embodiments, the specific heat capacity of the inner wall material of the heat insulation tube 252 is greater than that of the inner wall material of the heating chamber 24. The heating chamber 24, as a component for heating the aerosol matrix, has an inner wall material with good thermal conductivity. For example, the heating chamber 24 can be a metal tube, and its inner wall can be made of materials such as aluminum, stainless steel, permalloy, or copper. The outer wall of the heating chamber 24 contains a heating layer, which can be a resistance heating mesh / wire, a thick film heating layer, or other heating coating. The inner wall of the heating chamber is smooth and can further be a straight pipe. The inner wall material of the heat insulation tube 252 is different from that of the inner wall material of the heating chamber 24. The heat insulation tube 252 has a larger specific heat capacity, resulting in less heat absorption by the extension tube 251 and a lower temperature for the extension tube 251. This avoids the extension tube 251 becoming too hot, leading to a higher temperature at the bottom of the shell 3, and also reduces heat loss from the heating chamber 24. Specifically, the inner wall material of the heat insulation tube is selected from PEEK, polyimide, ceramic, or coated materials; these materials are high-temperature resistant.

[0136] The aerosol generating device in the above embodiments also includes an upper cover 26. One end of the upper cover 26 is connected to the upper end of the heating chamber 24, and the other end extends and connects to the top of the housing 3. The aerosol generating substrate can be fed into the heating chamber 24 from the upper cover 26 and heated. The filter end of the aerosol generating substrate can extend from the upper cover 26 for the user to inhale. In this embodiment, the heat insulation tube 252 constitutes the lower cover, which, together with the upper cover 26, clamps the heating chamber 24. Furthermore, the materials of the upper cover 26 and the lower cover are selected from PEEK, polyimide, ceramic, or coated materials, which can play a role in heat insulation.

[0137] refer to Figure 7-15 This invention proposes an aerosol generating device, including a smoke chamber 2 and a heat insulation assembly. The smoke chamber 2 is used to contain and heat the aerosol generating matrix. The heat insulation assembly includes a first heat insulation element, a secondary heat insulation element 42, and a housing 3, wherein the first heat insulation element is, for example, a vacuum heat insulation element 41. The housing 3 serves both as the outer packaging of the aerosol generating device and as heat insulation. Further, the housing 3 includes an inner shell 31 and an outer shell 32. Figure 7 and Figure 8 As shown, the vacuum insulation component 41 is fitted around the outer periphery of the smoke chamber 2, and the secondary insulation component 42 is fitted around the outer periphery of the vacuum insulation component. The secondary insulation component 42 is embedded inside the inner shell 31, and is therefore also enclosed and insulated by the inner shell 31. The outer shell 32 is fitted around the outer periphery of the inner shell 31, and a first insulation gap 33 exists between the outer shell 32 and the inner shell 31. Figure 6 As shown, the outer shell 32 completely encloses the inner shell 31, and there is a first heat insulation gap 33 between the inner wall of the outer shell 32 and the outer wall of the inner shell 31.

[0138] Existing methods of heat insulation for smoking devices involve making the casing relatively large, creating a significant gap between the casing and the heating chamber, forming a thick air layer to effectively block heat. This invention aims to achieve good heat insulation while miniaturizing the aerosol generator. Furthermore, simplifying the installation process and avoiding excessive complexity in the smoking device's structure are also directions for improvement in the aerosol generator of this invention.

[0139] Therefore, the aerosol generating device of the above embodiment combines five parts to achieve heat insulation. (1) The vacuum insulation component 41 is wrapped around the outer periphery of the smoke chamber 2. The inside of the vacuum insulation component 41 is in a vacuum state, which can play an excellent heat insulation role; (2) The vacuum insulation component 41 is wrapped by a secondary insulation component 42, which further enhances the heat insulation effect; (3) Utilizing the structural characteristics of the shell itself, the inner shell used to fix the components inside the shell 3 is also used as one of the heat insulation components to wrap the smoke chamber 2, the vacuum insulation component 41, and the secondary insulation component 42; (4) The outermost outer shell 32 of the shell 3 can still play a heat insulation role; (5) A first heat insulation gap is set between the outer shell 32 and the inner shell 31, that is, the air layer can also play a good heat insulation role. Practice has proven that, compared to simply using an air layer as insulation or relying entirely on nested rigid insulation components, this embodiment combines vacuum insulation, rigid insulation, and air layer insulation to achieve better insulation performance with the same insulation volume. Compared to methods that simply increase the size of the air insulation layer or the number of nested insulation components, the insulation component in this embodiment is smaller, simpler in structure, and easier to install.

[0140] Existing smoking devices use brackets to secure internal components within the outer shell. This embodiment utilizes an inner shell to secure the components, while the enclosed design effectively blocks heat from the smoke chamber, separating the internal battery and circuit board from the smoke chamber 2 – achieving multiple benefits. Simply increasing the number of heat-insulating components around the smoke chamber would result in one side of the smoke chamber being too large, leaving excessive unused space on the other side, leading to an uneven distribution of internal components and a less compact structure.

[0141] The aerosol generator described in the above embodiment exhibits excellent heat insulation. The key reason for this lies in the combination of the five structural components, which creates a discontinuous heat transfer path. Specifically, heat from the smoke chamber first passes through a vacuum insulation component, then through a secondary insulation component and the inner shell. Because the secondary insulation component and the vacuum insulation component, as well as the inner shell and the secondary insulation component, are disconnected rather than integrally formed, heat transfer is discontinuous. Subsequently, the air layer between the inner and outer shells acts as another transfer medium, further reducing heat transfer efficiency. Finally, the outer shell blocks most of the heat transfer. This combination of five structural components creates a discontinuous heat transfer medium; the multiple changes in the transfer medium reduce heat transfer efficiency, enhance the heat insulation effect, and slow down the rate of temperature rise on the outer shell surface.

[0142] Further reference Figure 7A second heat insulation gap 43 exists between the inner wall of the vacuum insulation component 41 and the outer wall of the smoke chamber 2, that is, an air layer is set between the vacuum insulation component 41 and the smoke chamber 2 to block heat. Furthermore, the two ends of the second heat insulation gap 43 are closed along the axial direction. Thus, the second heat insulation gap 43 acts as an air layer, reducing airflow and preventing a large amount of air from carrying away heat from the smoke chamber 2, thereby reducing heat loss. In this embodiment, closing the two ends of the second heat insulation gap 43 can be achieved by appropriately sealing the openings at both ends to reduce airflow. Preferably, the two ends of the second heat insulation gap 43 are completely closed, i.e., sealed, so that air cannot flow within the second heat insulation gap 43. The completely sealed second heat insulation gap 43 serves both as heat insulation and as heat preservation for the smoke chamber. Specifically, sealing elements can be provided at the opposite ends of the vacuum insulation component 41 along the axial direction and the smoke chamber 2, for example... Figure 7 As shown, a first sealing element 44 is provided to block the upper port of the second heat insulation gap 43, and a second sealing element 45 is provided to block the lower port of the second heat insulation gap 43.

[0143] The heat insulation components in the above embodiments allow for excellent heat insulation without requiring a large volume of the aerosol generator. Traditional smoking devices have a relatively thick air layer, while the thickness of the first heat insulation gap in this invention can be 0.1-10 mm, and the thickness of the second heat insulation gap can be 0.2-10 mm. Furthermore, the dimensions of the first and second heat insulation gaps within these ranges ensure effective heat insulation. Preferably, the thickness of the first heat insulation gap is 0.2-5 mm, and the thickness of the second heat insulation gap is 0.3-6 mm.

[0144] The aforementioned first heat insulation gap 33 is achieved by having the outer shell 32 fitted around the outer periphery of the inner shell 31, with the volume of the outer shell 32 being larger than the volume of the inner shell 31. Furthermore, multiple protrusion structures are provided on the outer wall of the inner shell or the inner wall of the outer shell to achieve contact limiting between the inner shell and the outer shell. In this embodiment, reference... Figure 6 The inner shell 31 has multiple protrusion structures 34 on its outer wall, which serve as contact points for the outer shell 32 to contact and limit its movement. The protrusion structures 34 restrict the freedom of the inner shell 31 in the four directions (front, back, left, and right) within the space of the outer shell 32, forming a stable assembly position. Furthermore, the protrusion structures 34 ensure that a first heat-insulating gap 33 is maintained between the inner shell 31 and the outer shell 32. Considering the stability of the contact positioning, this embodiment can have two, or more, or even four or more protrusion structures. Protrusion structures can be selectively provided on the four surfaces of the outer wall of the inner shell 31 or the four surfaces of the inner wall of the outer shell. It is preferable that protrusion structures 34 are distributed on all four surfaces of the outer wall of the inner shell 31. Alternatively, protrusion structures can be provided on all four surfaces of the inner wall of the outer shell.

[0145] In the above embodiments, the protrusion structure 34 is strip-shaped or dot-shaped, and the contact area between each protrusion structure 34 and the outer shell 32 is not less than 0.5 mm. 2 .

[0146] In the above embodiments, the inner shell 31 includes a front inner shell 311 and a rear inner shell 312. The front inner shell 311 and the rear inner shell 312 are joined to form a cavity for accommodating and holding the smoke chamber and other components within the shell. The inner shell 31 is the mounting base for the internal components, used to accommodate the smoke chamber 2 and other components, such as a vacuum insulation component 41, a secondary insulation component 42, a circuit board 51, an inner button part 61, a battery 52, and a battery fixing foam 53. After the inner shell 31 is locked, all internal components can be completely restricted in their degrees of freedom, achieving complete positioning.

[0147] The inner shell 31 encloses the smoke chamber 2 and is installed as a whole within the outer shell 32. After the outer shell 32 and the inner shell 31 make contact through the protrusion structure 34, the inner shell 31 is constrained by the inner wall of the outer shell 32 and subjected to installation clamping pressure, which can effectively control the consistency of the installation gap and eliminate the problem of inconsistent gaps caused by thermal expansion and contraction of materials and processing stress. After the inner shell 31 and the outer shell 32 are assembled, the protrusion structure plays a role in locking the assembly relationship.

[0148] In the above embodiments, the vacuum insulation component and the secondary insulation component are preferably made of high-temperature resistant insulation materials, such as PEEK or stainless steel. The inner shell can be made of ABS, PC, or PEEK, or a mixture of several of these materials. Additionally, glass fiber can be added to the inner shell. The outer shell comprises at least one material, which can be metal, such as aluminum alloy or zinc alloy; or plastic, such as a mixture of one or more materials including PC, ABS, and nylon, with added glass fiber. It can also be manufactured using plastic + metal through processes such as joining, plastic coating, or secondary injection molding.

[0149] In the above embodiments, the smoke chamber 2 is used to contain and heat the aerosol-generating matrix, and the heating method is, for example, peripheral heating or needle heating. For example, in this embodiment, refer to Figure 7 The smoke chamber 2 is formed by multiple end connections and includes a heating chamber 24, an extension tube 251, and an insulation tube 252. Since only the heating chamber 24 generates heat, the vacuum insulation component 41 and the secondary insulation component 42 can only wrap around the outer periphery of the heating chamber 24, and the extension tube 251 can extend axially relative to the vacuum insulation component 41 and the secondary insulation component 42. The second insulation gap between the smoke chamber 2 and the vacuum insulation component 41 is actually the gap between the outer wall of the heating chamber 24 and the inner wall of the vacuum insulation component.

[0150] refer to Figure 7 and Figure 8 The aerosol generating device in the above embodiments also includes an upper end cover 26. One end of the upper end cover 26 is connected to the upper end of the heating chamber 24, and the other end extends and connects to the top of the housing 3, so that the aerosol generating matrix can be fed in from the upper end cover 26. The heat insulation tube 252 constitutes the lower end cover, which, together with the upper end cover 26, clamps the heating chamber 24, ensuring that the heating chamber 24 is located inside the housing 3. In addition, the upper end cover 26 and the vacuum heat insulation member 41 are installed, positioned and sealed by the first sealing member 44 and the positioning sleeve on the heating chamber, and the heat insulation tube 252 and the vacuum heat insulation member 41 are installed, positioned and sealed by the second sealing member 45 and the lower end cover sleeve 47, thereby achieving a seal at both ends of the second heat insulation gap in the axial direction. Preferably, the first sealing member 44 and the second sealing member 45 are both made of silicone, which reduces the heat conduction speed while forming a seal.

[0151] The extension chamber 25 remains entirely within the housing 3. The extension tube 251, as an extension section, may not contain a cigarette, or, when the cigarette is long, a portion of it may extend from the heating chamber 24 into the extension tube 251. The cigarette within the chamber 2 is restrained by inserting an end plug 1 into the extension tube 251. In this embodiment, the heating chamber 24 can be a heating tube, and the heat insulation tube 251 and extension tube 252 have the same inner diameter as the heating chamber 24. These three are axially aligned and connected to form a straight-through structure, facilitating cleaning.

[0152] This invention proposes a housing assembly for use in an aerosol generator, used to assemble and fix internal components such as the smoke chamber, vacuum insulation component, secondary insulation component, and battery in the above embodiments.

[0153] refer to Figure 12-15 The outer casing assembly of this embodiment includes the aforementioned housing 3 and button mechanism. The housing 3 includes an inner shell 31 and an outer shell 32. In addition to the aforementioned heat insulation function, the inner shell 31 and outer shell 32 in this embodiment also serve to fix the internal components. The button mechanism includes an outer button portion 62 and an inner button portion 61. The outer shell 32 and the inner shell 31 are respectively provided with a first through hole 35 and a second through hole 36 arranged opposite to each other along a first installation direction. The inner button portion 61 is at least partially embedded in the second through hole 36, and the outer shell 32 is sleeved on the outer periphery of the inner shell 31. The outer button portion 62 passes through the first through hole 35 and the second through hole 36 along the aforementioned first installation direction and docks with the inner button portion 61. Thus, the button mechanism constitutes a locking structure to prevent the outer shell 32 from detaching from the inner shell 31.

[0154] The locking structure formed by the button mechanism allows for the locking of the outer shell 32 after the outer button part 62 is installed. Since the outer shell 32 is fitted onto the outer periphery of the inner shell 31 along the second installation direction, the locking structure formed after the outer button part 62 is installed restricts the freedom of the outer shell 32 in the second installation direction, preventing it from detaching from the inner shell 31 along this direction. The second installation direction is, for example,... Figure 15 The x-direction in the second mounting direction. The outer shell 32 includes a first outer shell 321 and a second outer shell 322, which are respectively fitted onto the outer periphery of the inner shell 31 in two opposite directions along the second mounting direction, thereby achieving docking.

[0155] The specific installation sequence of the housing assembly is as follows: The inner button portion 61 is installed inside the inner housing 31 and connected to the circuit board 51. Then, the front inner housing 311 and the rear inner housing 312 are mated together to clamp the components inside the inner housing 31. Next, the first outer housing 321 and the second outer housing 322 of the outer housing 32 are mated together and fitted onto the outer periphery of the inner housing 31 along two opposing directions in the second installation direction. Afterward, the outer button portion 62 is mounted on the housing 3 along the first installation direction and fixed to the inner button portion 61. The first installation direction is, for example,... Figure 16 In the z-direction. After the outer button part 62 is installed, the outer shell 32 cannot be disassembled from the inner shell 31 without removing the outer button part 62. At the same time, the outer button part 62 is fixed by engaging with the inner shell 31, preventing it from excessively recessing or falling out relative to the first through hole 35 and the second through hole 36. In this way, the outer shell 32 can be fixed relative to the inner shell 31, avoiding glue application, eliminating glue holding time, improving production line efficiency, and increasing automation. The button mechanism itself is also difficult for the user to disassemble, and consequently, the outer shell and inner shell are also inconvenient to disassemble, achieving a limit and anti-disassembly function.

[0156] In the above embodiments, "outer" and "inner" in the outer button portion 62 and inner button portion 61 are relative concepts. That is, the outer button portion 62 is located relatively to the outside, while the inner button portion 61 is located further inside the outer casing assembly than the outer button portion 62. The inner button portion 61 of the present invention is at least partially located within the second perforation 36, thus being closer to components such as the circuit board 51, battery 52, and smoke chamber 2 within the inner casing 31, and thus receiving more heat. Since the outer button portion 62 and the inner button portion 61 are not integrally formed, even if the inner button portion 61 absorbs heat, the heat transfer to the outer button portion 62 is significantly reduced. It has been proven that, compared to having only one button structure on the outer casing assembly, the button mechanism of the present invention, comprising two independent outer button portions 62 and inner button portions 61, can effectively reduce the surface temperature of the button on the outer casing 32, preventing the user from feeling hot when pressing the outer button portion 62.

[0157] As described above, the protrusion structure 34 on the inner shell 31 allows for a first heat-insulating gap between the outer shell 32 and the inner shell 31. At the same time, the outer shell 32 abuts against the outer periphery of the inner shell 31. That is, after the outer shell 32 is fitted onto and abuts against the inner shell 31, appropriate pressure is applied to the inner shell 31. Since the inner shell 31 includes the front inner shell 311 and the rear inner shell 312, the outer shell 32 is already locked. Thus, the front inner shell 311 and the rear inner shell 312 are also bound and will not separate. Then, through the pin locking action of the button mechanism, the locking of the outer shell 32 and the inner shell is completed.

[0158] Furthermore, after the outer button part 62 is properly installed with the inner button part 61, the position of the outer button part 62 is fixed, so that it will not be completely inserted into the inner sleeve 31, nor will it separate from the inner button part 61 and completely come out of the outer sleeve 32, thus ensuring that the locking action is effective.

[0159] Specifically, refer to Figure 14 The inner button portion 61 is installed inside and fixed within the inner housing 31. Due to the fitting of the outer housing 32, the front inner housing 311 and the rear inner housing 312 are clamped together, resulting in a portion of the end face of the inner button portion 61 being covered by the inner side of the inner housing 31, while the other portion protrudes through the second through-hole 36. The inner housing 31 abuts against the inner button portion 61, and simultaneously, the inner button portion 61 abuts against the circuit board inside the housing 3, thus fixing the inner button portion 61. The outer button portion 62 passes through the first through-hole 35 and the second through-hole 36 along the first mounting direction and engages with the housing 3 or the inner button portion to prevent the outer button portion 62 from detaching from the outer housing 32. That is, the outer button portion 62 engages with the outer housing, or with the inner housing, or with the inner button portion, restricting its movement in the direction opposite to the first mounting direction. For example… Figure 14 In the middle, that is, it restricts its movement to the left. Since the outer button part 62 is mated with the inner button part 61, and the inner button part 61 is fixed, the outer button part 62 can also be restricted from continuing to move along the first mounting direction, for example... Figure 14 In the middle, that is, it is restricted from moving to the right.

[0160] Furthermore, the outer button portion 62 has a first engaging portion for locking, such as one or more hooks 63, which protrude into the housing 3 after installation. The housing or inner button portion has a second engaging portion corresponding to the first engaging portion, such as a groove 64 corresponding to the hook 63. Through the locking and limiting action of the hook 63 and the groove 64, the outer button portion 62 will not dislodge outside the outer housing. More specifically, as... Figure 14As shown, the groove 64 is located inside the second perforation 36, that is, the groove 64 is provided inside the inner shell 31, more specifically around the periphery of the hole wall of the second perforation 36 in the inner shell 31. The groove 64 being located inside the second perforation 36 helps maintain the relative positional relationship between the outer button portion and the inner button portion, and no structural features appear on the outer surface of the outer shell. Correspondingly, the hook 63 is provided around the outer button portion 62. The outer button portion 62 has an open end 621, which connects to the inner button portion 61, and the hook 63 is provided at the open end 62.

[0161] In the above embodiments, the hook 63 is an elastic wall hook, that is, the extension arm of the hook 63 is elastic and can undergo moderate deformation, which is beneficial for the hook 63 to be embedded in the second through hole 36 and hook back the groove 64.

[0162] In the above embodiments, the outer shell 32 is fitted onto the inner shell 31 along the second mounting direction, and the first mounting direction is not parallel to the second mounting direction. That is, the first mounting direction and the second mounting direction form an angle. Further, the first mounting direction is substantially perpendicular to the second mounting direction. Substantially perpendicular includes the first mounting direction being perpendicular to the second mounting direction, and also includes moderate errors in manufacturing in the art. At this time, the angle between the first mounting direction and the second mounting direction is substantially 90 degrees, including an angle of 90 degrees and within an allowable error range.

[0163] In the above embodiments, the inner button portion 61 further includes a first light guide component 65. The first light guide component 65 has multiple independent first light guide portions 651. The multiple first light guide portions 651 correspond one-to-one with multiple light-emitting components in the housing 3. For example, multiple light-emitting components are provided on the circuit board 51, and each light-emitting component corresponds to a first light guide portion 651 for light guiding. The outer button portion 62 is provided with multiple light-transmitting holes 622 corresponding to the light transmission of each first light guide portion 651. Each first light guide portion 651 transmits the light emitted by the light-emitting component through the corresponding light-transmitting hole 622 so that it can be observed. The inner button portion 61 of the present invention is provided with a plurality of through holes 611 extending from the inside to the outside. A plurality of first light guide portions 651 are embedded in the through holes 611 of the inner button portion 61. Since the plurality of through holes 611 are spaced apart from each other, the embedded first light guide portions 651 are spaced apart from each other by the inner button portion 61. In this way, the light transmitted by the first light guide portions 651 will not affect each other and will transmit light independently through the light-transmitting hole 622, avoiding interference between multiple beams of light and making it easier for users to observe the status changes of the indicator light, the number of lights, etc.

[0164] Furthermore, the outer button portion 62 also includes a second light guide assembly 66, which has multiple independent second light guide portions 661. Each of the multiple second light guide portions 661 corresponds one-to-one with a multiple first light guide portions 651. The second light guide portions 661 are used to transmit light from the first light guide portions 651 to the corresponding light-transmitting holes 622. In other embodiments, when the inner button portion and / or the outer button portion is too thin to easily install a light guide, a light guide may not be installed. Instead, a light guide point can be achieved by partially reducing the adhesive to create a thin-walled, light-transmitting component, drilling holes, or using a secondary injection-molded light-transmitting insert.

[0165] In the above embodiments, the outer button portion and the inner button portion are connected without gaps, allowing them to move synchronously. Specifically, this gapless connection can be a magnetic connection, a tight-fit connection, a snap-fit ​​connection, or an adhesive connection. When a magnetic connection is selected, an outer magnetic body 623 can be provided on the outer button portion 62, and an inner magnetic body 612 can be provided on the inner button portion 61. The inner magnetic body 612 is fixed to the inner button portion 61, and the outer magnetic body 623 is fixed to the outer button portion 62. The outer button portion 62 and the inner button portion 61 are connected through the contact between the inner magnetic body 612 and the outer magnetic body 623.

[0166] In the above embodiments, the maximum protrusion height of the outer surface of the outer button portion 62 relative to the outer surface of the outer shell 32 does not exceed 0.5mm, and the maximum recessed depth does not exceed 2mm. Excessive protrusion of the outer surface of the outer button portion 62 relative to the outer surface of the outer shell 32 can easily lead to accidental touches by the user, while excessive recessed depth is also detrimental to user pressing and use. Preferably, the outer surface of the outer button portion is set to be substantially flush with the outer surface of the outer shell. Furthermore, a moderate recess of the outer button portion will not affect the locking function of the outer shell 32. This can be achieved by setting the curvature of the outer shell surface or by additionally providing a connecting component to the outer shell on the outer button portion, as long as the button mechanism can form a locking structure to prevent the outer shell from detaching from the inner shell along the second mounting direction.

[0167] The present invention also proposes an aerosol generating device for heating an aerosol generating matrix, including the outer shell assembly in the above embodiments, that is, including the button mechanism and other components in the above embodiments.

[0168] The outer and inner button parts are made of materials with good appearance processing properties, such as plastics (ABS, PP, PC, POM, PBT, etc.) and metals (aluminum alloy, zinc alloy, etc.). The first and second light guide parts are made of transparent materials such as ABS, PC, acrylic, etc. The inner and outer button parts can be joined with the first and second light guide parts by means of tight fitting, bonding, secondary injection molding, or filling with transparent glue.

[0169] Various embodiments of the end plug, smoke chamber, heat insulation component, and outer shell component can be combined with each other to form an aerosol generating device.

[0170] While the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the invention to these descriptions. Various changes in form and detail can be made by those skilled in the art, including several simple deductions or substitutions, without departing from the spirit and scope of the invention.
