Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically to a heating non-combustible device. Background Technology

[0002] Heated non-combustible devices utilize their own heating elements to heat an aerosol-generating matrix, thereby producing aerosols. Airtightness is a key performance characteristic of heated non-combustible devices. Good airtightness is crucial for ensuring the efficient and stable operation of the device. Poor airtightness will, on the one hand, affect the quality of aerosol generation, causing the aerosol concentration to deviate from ideal levels, thus impacting the user experience; on the other hand, it will also shorten the lifespan of the heated non-combustible device.

[0003] In related technologies, silicone sealant is commonly used as a sealing material to achieve effective sealing inside heated non-combustible devices. However, in actual use, these devices generate high temperatures during operation. When silicone sealant is exposed to this high-temperature environment for extended periods, its performance gradually deteriorates. For example, the elasticity of the silicone decreases, preventing it from tightly adhering to the sealing areas of the device, thus causing the seal to gradually fail. This not only reduces the performance of the heated non-combustible device but may also lead to a series of problems such as leakage and reduced heating efficiency. Utility Model Content

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0025] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0026] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0027] Heated non-combustible devices are used to heat an aerosol generating matrix to generate an aerosol for user use. These devices contain multiple components, such as a heating element, a power supply element, and a housing element. The presence of multiple components leads to sealing issues within the heated non-combustible device; as described in the background section, poor sealing can affect the device's performance and lifespan. To address this issue, multiple sealing structures are incorporated within the heated non-combustible device to achieve a sealed connection between adjacent components.

[0028] Sealing structures come in various forms. One type is internal filling, where the sealing structure is filled into the gap between two components, such as a sealing ring. Another type is external wrapping, where the sealing structure is fitted over the outside of the two components to achieve a sealed connection.

[0029] Sealing structures are generally made of elastic polymers, utilizing their elastic properties to achieve a seal. For example, sealing structures include rubber or silicone. Because the heated non-combustible device generates high temperatures during operation, the sealing structure is exposed to high-temperature environments (70℃-150℃) for a long time, which will gradually age, weaken its elasticity, and eventually lead to the failure of its sealing function.

[0030] To address the aforementioned problems, this application provides a novel sealing structure for use within a heated non-combustible device to improve its internal sealing performance. It is important to emphasize that this sealing structure achieves its sealing function through an external enclosure; this means that all subsequent discussions of the sealing structure will be based on this enclosure method. Before introducing the heated non-combustible device with this sealing structure, some terms used in this application will be explained.

[0031] The term "aerosol" as used herein refers to a dispersion of solid or liquid particles in a gas. As used herein, "aerosol" may also refer to a substance that has been vaporized, atomized, sprayed, or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0032] The aerosol-generating matrix is ​​any suitable compound or mixture of compounds that facilitates aerosol formation in use. This aerosol-generating matrix includes, but is not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono, di, or triacetic acid esters of glycerol; and aliphatic esters of mono, di, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate. Nicotine may also be included. Alternatively, glycerol (also known as glycerol) with a higher boiling point than nicotine may be included. Propylene glycol or plant-based materials may also be included.

[0033] The aerosol-generating matrix may also include flavoring agents, which are materials used in products to produce the taste, aroma, or other bodily sensations desired by the user. Flavoring agents may include naturally occurring flavoring materials, plants, plant extracts, synthetically obtained materials, or combinations thereof. For example, flavoring agents may include menthol, fruit extracts (such as strawberry, watermelon, apple, etc.).

[0034] Please see Figures 1 to 7 The heated non-combustible device provided in this application includes a housing assembly 100, a connecting member 500, and a sealing structure 400 disposed on the connecting member 500. The sealing structure 400 includes a sealing element 410 and a heat-shrinkable sleeve 420. At least a portion of the sealing element 410 is fitted over the outside of the connecting member 500, and at least a portion of the heat-shrinkable sleeve 420 is fitted over the outside of the sealing element 410. The sealing element 410 is tightly connected to the outer surface of the connecting member 500 under the heat shrinking action of the heat-shrinkable sleeve 420.

[0035] In some embodiments, the connecting component 500 includes, but is not limited to, the heating assembly 200 and the airflow channel 300, and also includes other structures not listed herein suitable for external sealing within the heated non-combustible device. The heating assembly 200 is disposed within the housing assembly 100 and is used to heat the aerosol generating matrix to generate an aerosol. The airflow channel 300 is formed within the housing assembly 100 and communicates with the heating assembly 200, and is used to guide airflow, which includes not only air entering the heated non-combustible device from the external environment but also a mixture of air and aerosol. That is, the airflow channel 300 guides outside air into the heated non-combustible device to assist in aerosol generation, and can also guide the mixture of air and aerosol to flow to the user. A sealing structure 400 is disposed between the heating assembly 200 and the housing assembly 100, and / or, the sealing structure 400 is disposed outside the airflow channel 300.

[0036] The housing assembly 100 can be understood as an assembly of multiple structures. The combination of these structures forms a cavity that houses the heating component 200. When the heating component 200 is assembled within this cavity, a sealing requirement exists between the heating component 200 and the cavity's structural components to prevent gas or liquid leakage. Specifically, a sealing structure 400 is required between the heating component 200 and the housing assembly 100. Furthermore, the multiple structures may also form an airflow channel 300. To ensure smooth airflow and maintain good airtightness, a sealing structure 400 is also required when the multiple structures are combined. This means a sealing structure 400 is placed outside the airflow channel 300. In practical applications, the sealing structure 400 can be placed either between the heating component 200 and the housing assembly 100 or outside the airflow channel 300 to ensure good airtightness inside the heating non-combustible device and effectively prevent gas or liquid leakage.

[0037] Please see Figure 2 At least a portion of the sealing element 410 is fitted over the outside of the connecting component 500, and at least a portion of the heat-shrink sleeve 420 is fitted over the outside of the sealing element 410. The sealing element 410 is tightly connected to the outer surface of the connecting component 500 under the heat-shrinking action of the heat-shrink sleeve 420. In some embodiments, the sealing element 410 is used to connect the heating component 200 and the housing component 100. The heat-shrink sleeve 420 deforms and compresses the sealing element 410 after being heated, compressing the gap between the sealing element 410 and the heating component 200 until it disappears, thus achieving a tight connection between the heating component 200 and the housing component 100. In other embodiments, the sealing element 410 is used to achieve a sealed connection of the airflow channel 300, and the heat-shrink sleeve 420 is used to further improve its sealing effect, solving the problem of functional failure of the sealing element 410 under high-temperature environments and achieving a long-lasting seal.

[0038] In this application, the heat shrink sleeve 420 is fitted onto the outside of the seal 410, and the seal 410 is squeezed by the extrusion force of the heat shrink deformation to achieve a seal. This includes the heat shrink sleeve 420 being directly fitted onto the outside of the seal 410 and tightly connected to the seal 410 after heat shrink deformation, and also includes a connecting medium being provided between the heat shrink sleeve 420 and the seal 410, so that the extrusion force generated by the heat shrink sleeve 420 after heat deformation is indirectly applied to the seal 410 through the connecting medium.

[0039] The extension length of the 420 heat shrink sleeve is unlimited, such as... Figure 3 As shown, the extension length can be less than or equal to that of the seal 410, such as... Figure 4 and Figure 5As shown, the length can also be greater than that of the seal 410, so that a portion of the seal 410 is connected to the outer surface of the heating assembly 200 or the airflow channel 300 after heat shrinking. The extension length of the heat shrink sleeve 420 is selected to ensure that the heat shrink sleeve 420 has sufficient compressive force to tightly connect the seal 410 to the outside of the heating assembly 200 or the airflow channel 300 when it shrinks.

[0040] In some embodiments, please continue reading Figures 3 to 5 The heat shrink sleeve 420 includes a first heat shrink section 421 and a second heat shrink section 422 connected along its axial direction. The first heat shrink section 421 is disposed outside the seal 410, and the second heat shrink section 422 is disposed outside the connecting member 500. Specifically, the seal 410 and the heating assembly 200 or the airflow channel 300 are externally interference-fitted. However, after long-term use in a high-temperature environment, the structure and performance of the seal 410 fail, resulting in a gap between it and the exterior of the heating assembly 200 or the airflow channel 300. The tightening force of the first heat-shrinkable section 421 located on the exterior of the seal 410 due to heat shrinkage can reduce or even eliminate the gap. The second heat-shrinkable section 422 is located on the exterior of the heating assembly 200 or the airflow channel 300 and connected to the first heat-shrinkable section 421. When the second heat-shrinkable section 422 is tightly connected to the outer surface of the heating assembly 200 or the airflow channel 300, a sealed space is formed between the first heat-shrinkable section 421, the second heat-shrinkable section 422, the seal 410, and the heating assembly 200 (or the seal 410 and the airflow channel 300), which can further improve the sealing effect. In some embodiments, the heat-shrinkable sleeve 420 is a cylinder.

[0041] In some embodiments, the cross-sectional area of ​​the first heat-shrinkable section 421 is larger than the cross-sectional area of ​​the second heat-shrinkable section 422. The first heat-shrinkable section 421 is directly and tightly connected to or indirectly connected to the outer surface of the seal 410, and the second heat-shrinkable section 422 is tightly connected to the outer surface of the airflow duct or heating assembly 200 disposed inside the seal 410.

[0042] For further information, please refer to [link / reference]. Figure 4 In some embodiments, the second heat-shrinkable section 422 includes a tapered section 4221 and an extended section 4222. The tapered section 4221 is disposed between the extended section 4222 and the first heat-shrinkable section 421. In the direction away from the first heat-shrinkable section 421, the cross-section of the tapered section 4221 gradually decreases. The cross-sectional dimensions of the first heat-shrinkable section 421 and the second heat-shrinkable section 422 are different. The tapered section 4221 provides a buffer section for the change in cross-sectional dimensions, which can effectively avoid stress changes caused by abrupt changes in size and prevent the heat-shrinkable sleeve 420 from deforming due to stress problems, thereby affecting its sealing performance.

[0043] In some embodiments, the connecting component 500 includes at least two connecting segments, with adjacent connecting segments sealed together by a sealing structure 400. For example, the connecting component 500 includes a first connecting segment 510 and a second connecting segment 530. In this embodiment, the first connecting segment 510 and the second connecting segment can be connected by a sleeve or by a seal 410 in the sealing structure 400, and then a heat-shrink sleeve 420 is used to achieve a tight connection. For example, as... Figure 4 As shown, the first connecting segment 510 and the second connecting segment 520 are of equal diameter and are arranged sequentially along the axial direction of the connecting component 500. The sealing element 410 is sleeved on the outside of both segments to achieve their connection. For example, as... Figure 5 As shown, the diameter of the first connecting section 510 is smaller than that of the second connecting section 520. The second connecting section 520 is sleeved on the outside of the first connecting section 510. A variable diameter seal 410 is provided on its outside so that the inner wall of the seal 410 is interference-fitted with the outer surfaces of the first connecting section 510 and the second connecting section 520. The heat shrink sleeve 420 is used to avoid the problem of high temperature failure of the seal 410.

[0044] In practical applications, when the connecting component 500 includes an airflow channel 300, the airflow channel 300 includes multiple interconnected airflow segments, and a sealing structure 400 is provided between adjacent airflow segments. Specifically, in designing a heated non-combustible device, in order to make the structure more compact, the airflow channel 300 inside the housing assembly 100 is a non-straight-through tortuous structure, and the airflow channel 300 includes two or more airflow segments, with a sealing structure 400 required at the joint of adjacent airflow segments.

[0045] In some embodiments, the airflow channel 300 includes a first airflow segment and a second airflow segment continuously arranged, the first airflow segment being equivalent to a first connecting segment 510 and the second airflow segment being equivalent to a second connecting segment 520. A sealing structure 400 is disposed between the first airflow segment and the second airflow segment. The connection between the first airflow segment and the second airflow segment includes at least a portion of the first airflow segment being fitted over the outside of the second airflow segment to achieve connection, and the sealing structure 400 is used to further improve the connection stability and sealing performance. Alternatively, the first airflow segment and the second airflow segment can be connected through the sealing structure 400, meaning the sealing structure 400 serves both to achieve connection between the first airflow segment and the second airflow segment and to achieve sealing. When the first airflow segment is fitted over the second airflow segment, a portion of the sealing element 410 is fitted over the outside of the first airflow segment and a portion is fitted over the outside of the second airflow segment. A heat-shrink sleeve 420 is fitted over the outside of the sealing element 410, and under heat shrinkage, the sealing element 410 and the first airflow segment 310 and the second airflow segment 320 are compressed. In this embodiment, to further improve the sealing effect, the extension length of the heat shrink sleeve 420 is greater than the extension length of the seal 410. This allows it to completely cover the seal 410, as well as its end and the connection point between the first and second airflow sections. When the first and second airflow sections are sealed together by the sealing structure 400, the ends of the first airflow sections are either adjacent or spaced apart. One end of the seal 410 is fitted over the outside of the first airflow section, and the other end is fitted over the outside of the second airflow section. The heat shrinkage effect of the heat shrink sleeve 420 achieves compression. Of course, the extension length of the heat shrink sleeve 420 can also be greater than the extension length of the seal 410.

[0046] As mentioned above, the airflow channel 300 can be formed by combining parts of multiple structures that make up the housing assembly 100, or it can be formed by an airflow pipe independently disposed in the housing assembly 100. The airflow pipe is formed by connecting at least two pipes, and a sealing structure 400 is provided at the connection between two adjacent pipes, which can both connect the two into one and have a good sealing effect.

[0047] When the connecting component 500 includes the heating assembly 200, the heating assembly 200 and the housing assembly 100 correspond to the first connecting section 510 and the second connecting section 520, and their connection method has been described in detail above and will not be repeated here. At this time, at least one sealing structure 400 is provided, and at least one sealing structure 400 is provided at one end of the heating assembly 200. There are many types of heated non-combustible devices, and different types have different air intake methods. For example, heated non-combustible devices have upper air intake and lower air intake methods. When it is a lower air intake type, a sealing structure 400 is provided at the lower part of the heating assembly 200. When it is an upper air intake type, sealing structures 400 are provided at both the upper and lower parts of the heating assembly 200. Of course, when the heating assembly 200 is composed of multiple components, and there is a sealing requirement between the multiple components, and the installation conditions of the outer sealing element 410 are met, a sealing structure 400 can be provided in all cases.

[0048] Please see Figure 6 and Figure 7 Two sealing structures 400 are provided, and the two sealing structures 400 are respectively disposed at both ends of the heating assembly 200. In some embodiments, the heating assembly 200 includes a support tube 210 and a heating element 220 inside the support tube 210. The two ends of the support tube 210 are connected to the internal structure of the housing assembly 100. Two sealing members 410 are respectively sleeved between the two ends of the support tube 210 and the housing assembly 100. A heat shrink sleeve 420 is provided on the outside of each of the two sealing members 410. The heat shrink sleeve 420 can be a heat shrink tube. The sealing member 410 has an annular structure to adapt to the shape of the support tube 210. Specifically, the sealing structure 400 includes a first sealing element 411 and a second sealing element 412, as well as a first heat shrink sleeve 423 and a second heat shrink sleeve 424. The first heat shrink sleeve 423 is disposed outside the first sealing element 411, and the second heat shrink sleeve 424 is disposed outside the second sealing element 412. The first heat shrink sleeve 423 and the first sealing element 411 cooperate to seal the upper end of the support tube 210, and the second heat shrink sleeve 424 and the second sealing element 412 cooperate to seal the lower end of the support tube 210.

[0049] The shapes of the airflow duct and heating component 200 are unrestricted; their cross-sections can be cylindrical (including near-cylindrical and elliptical bodies), cubic, or irregularly shaped. The seal 410 is an elastic sealing material, capable of conforming to the exterior of any shape of airflow duct or heating component 200 to achieve a sealing effect. The elastic sealing material includes at least one of rubber, silicone, or thermoplastic elastomers. When the seal 410 is located outside the heating component 200, a high-temperature resistant silicone material is selected for the seal 410 due to the high operating temperature of the heating component 200.

[0050] In some embodiments, the heat shrink sleeve 420 is made of a heat-shrinkable polymer, which refers to a polymer that can shrink under heating conditions, and the tightening force generated by this shrinkage can tightly wrap its internal structure. The polymer material heat shrink sleeve 420 includes at least one of polyvinylidene fluoride, perfluoroethylene propylene, soluble polytetrafluoroethylene, polytetrafluoroethylene, and fluororubber.

[0051] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
