Description

Technical Field

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

[0002] Heated non-combustible devices can generate aerosols by heating solid aerosol generating products. One of the commonly used heating methods is central heating, in which the heated non-combustible device has a heating element. During use, the aerosol generating product is inserted into the heating element, thereby using the heating element to heat the aerosol generating product from the inside.

[0003] One method of setting up the heating element is to wrap a heating resistance wire around the outside of a heat-conducting substrate. However, this method suffers from uneven heating across the surface of the heating element, which can easily affect the flavor of the generated aerosol. Another method involves inserting a heating resistance wire inside a heat-conducting pipe. This type of heating element requires preheating during use. If the preheating time is too long, the temperature can become too high, causing the aerosol product to burn at the outlet, which can also negatively impact the flavor of the generated aerosol. Utility Model Content

[0004] In order to reduce the risk of aerosol flavor being affected by heating, this application provides a new heating element and a heating non-combustible device.

[0005] According to a first aspect, one embodiment provides a heating element, comprising:

[0006] The heating element is configured to be activated to generate heat.

[0007] And a heat-conducting component, having a mounting cavity, wherein the heating core is disposed in the mounting cavity to transfer heat to the heat-conducting component;

[0008] The outer surface of the heat-conducting component is provided with a gas-guiding channel to reduce the contact area between the heat-conducting component and the aerosol-generating product, and to allow the heat-conducting component to heat and generate a hot airflow, so as to utilize the convection of the hot airflow and the radiation of the channel wall of the gas-guiding channel to heat the aerosol-generating product.

[0009] In one embodiment, the air guide channel is a straight air guide channel arranged parallel to the axial direction of the heat-conducting element; and / or, the air guide channel is a spiral groove arranged around the circumference of the heat-conducting element.

[0010] In one embodiment, the outer surface of the heat-conducting element is provided with a groove to serve as the air guiding channel; or, the outer surface of the heat-conducting element is provided with at least two protrusions, and the air guiding channel is formed between adjacent protrusions.

[0011] In one embodiment, the outer surface of the heat-conducting element is provided with a plurality of recesses, which are arranged sequentially and adjacent recesses intersect to form the groove.

[0012] In one embodiment, the outer surface of the heat-conducting element is etched to form the air-guiding channel, and at least two air-guiding channels are arranged circumferentially around the heat-conducting element.

[0013] In one embodiment, the heat-conducting element includes an insertion portion for insertion into an aerosol-generating article and an exposed portion for exposure to the outside of the aerosol-generating article, the air-conducting channel having an air inlet located in the exposed portion.

[0014] In one embodiment, the heat-conducting element includes a cylindrical section and a conical tip section. The conical tip section is used to guide the insertion of the cylindrical section into the aerosol-generating product. The gas-guiding channel is disposed on the cylindrical section. The maximum outer diameter of the conical tip section is not less than the outer diameter of the cylindrical section, which is used to restrict the aerosol matrix in the aerosol-generating product from entering the gas-guiding channel when the heating element is inserted into the aerosol-generating product.

[0015] In one embodiment, the heat-conducting element is made of at least one of ceramic, glass, or metal;

[0016] When the material of the heat-conducting component includes metal, a thermally conductive insulating layer is provided between the heating core and the metal part of the heat-conducting component.

[0017] In one embodiment, the outer surface of the heat-conducting element is covered with a radiation-emitting layer, the radiation emissivity of which is higher than that of the heat-conducting element.

[0018] According to a second aspect, one embodiment provides a heating non-combustible device, comprising:

[0019] Power supply device;

[0020] The heating element described in any of the above embodiments, wherein the power supply device is used to supply energy to the heating element to stimulate the heating element to generate heat.

[0021] The heating element in the above embodiment utilizes a nested design of the heating core and the heat-conducting component to form a gradient heat transfer path. The heat is homogenized by the heat-conducting component and then transferred to the aerosol-generating product. Compared to an externally wound heating resistance wire structure, this helps to create a more uniform heating temperature field, thereby improving the consistency of aerosol flavor. Furthermore, by providing air-guiding channels on the outer surface of the heat-conducting component, the contact area between the component and the aerosol-generating product is reduced, thus lowering the risk of localized overheating. Simultaneously, airflow allows heat to diffuse from the contact area outwards, forming a dynamic thermal balance mechanism to prevent excessive heat accumulation in a single location. This reduces the likelihood of the aerosol-generating product burning and helps minimize the risk of the aerosol flavor being affected.

[0022] The channel walls of the air-guiding channel can be heated by thermal radiation, forming a composite heating system together with contact conduction and airflow convection. Although the reduced contact area caused by the air-guiding channel will decrease some heat conduction efficiency, this loss can be compensated by convection and radiation heating, and airflow convection helps accelerate the spatial distribution of heat. The synergistic effect of these three heat transfer methods not only improves overall heating efficiency but also enhances heating quality through the diversity of heat transfer paths. This helps ensure the uniformity and stability of heat distribution during aerosol generation, achieving efficient and synchronous aerosol release to preserve aerosol flavor.

[0030] 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.

[0031] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0032] 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).

[0033] For a central heating element inserted into the aerosol matrix for heating in a heated non-combustible device, one method is to wrap a heating resistance wire around the outside of the heat-conducting substrate and use the heating of the resistance wire to directly heat the aerosol to generate product 400. Although the heating efficiency is high, there is a problem of uneven heating at different positions on the surface of the heating element, which makes the aerosol generated at different heating positions have large differences and can easily affect the flavor of the aerosol.

[0034] Another way to set up the heating element is to insert a heating resistance wire into a heat-conducting pipe. The outer surface of the heat-conducting pipe is usually a continuous smooth surface, which will be in close contact with the aerosol matrix in the aerosol generating product 400. This allows the heat generated by the heating resistance wire to be conducted to the aerosol generating product 400 through the outer surface of the heat-conducting pipe for heating. This type of heating element requires a long preheating time when heating the aerosol generating product 400. Also, due to the large contact heat transfer area, heat accumulates in the contact area between the aerosol generating product 400 and the heating element, making the contact area easy to burn and affecting the flavor of the generated aerosol.

[0035] In this embodiment, a gradient heat transfer path is formed by the nested design of the heating core 100 and the heat-conducting element 200, enabling the heat-conducting element 200 to homogenize the heat before transferring it to the aerosol-generating product 400, thus improving heating uniformity. By further providing air-guiding channels 220 on the outer surface of the heat-conducting element 200, the direct contact area between the heat-conducting element 200 and the aerosol-generating product 400 is reduced through structural improvements, weakening conductive heating. Furthermore, airflow diffusion accelerates heat transfer and dispersion, reducing the risk of overheating in the contact area and improving heating efficiency. Moreover, the channel walls of the air-guiding channels 220 can radiate heat to the aerosol-generating matrix, compensating for the heating effect. The synergistic use of these three heating methods helps reduce the risk of uneven heating or localized overheating, ensuring aerosol flavor and improving the overall heating efficiency of the heating element.

[0036] Examples of heating elements in this application:

[0037] In one embodiment, please refer to Figure 1 and Figure 2 The heating element includes a heating core 100 and a heat-conducting element 200; the heating core 100 is configured to be excited to generate heat, and the heat-conducting element 200 has a mounting cavity 210 in which the heating core 100 is disposed to transfer heat to the heat-conducting element 200.

[0038] The nested design of the heating core 100 and the heat-conducting component 200 can form a gradient heat transfer path. The heat is homogenized by the heat-conducting component 200 and then transferred to the aerosol generating product 400. Compared with the heating element structure with the heating resistance wire wrapped around it, this helps to form a more uniform heating temperature field, which shortens the time difference for the volatilization of the aerosol matrix in the aerosol generating product 400, thereby improving the consistency of aerosol flavor.

[0039] The heating core 100, as the heat source generating unit in the heating element, can have various configuration forms. For example, the heating core 100 can be a resistive core containing resistive heating materials, such as metal alloys or conductive ceramics, to generate heat after being excited by electricity. The heating core 100 can also be an electromagnetic induction core, which generates eddy current heating when excited by an alternating magnetic field. The material of the electromagnetic induction core can include ferromagnetic metals such as 430 stainless steel or iron-silicon-aluminum magnetic powder cores. The heating core 100 can also be formed by a thick film heating layer disposed on the cavity wall of the mounting cavity 210. In short, the configuration form and excitation method of the heating core 100 are not limited, as long as it can generate enough heat to heat the aerosol generating product 400.

[0040] Furthermore, it is understood that the heating core 100 can be configured as a columnar core, a sheet-like core, a mesh core, or other shapes and structures, and can be placed in the mounting cavity 210 to transfer the heat generated therefrom to the heat-conducting component 200.

[0041] The heat-conducting component 200 is used to transfer heat energy to the aerosol-generated product 400. Therefore, the heat-conducting component 200 can be made of at least one of ceramic, glass, metal or other high thermal conductivity materials, so as to achieve efficient heat conduction while also homogenizing heat and improving heating uniformity.

[0042] When the heat-conducting component 200 is made of metal, special attention must be paid to insulation. Specifically, if the heat-conducting component 200 is made of metal and the heating core 100 is an electrically activated core type, a thermally conductive insulating layer is required between the heating core 100 and the metal part of the heat-conducting component 200 to ensure safe use. This insulating layer can be an adhesion layer made of ceramic materials such as alumina or aluminum nitride, which have both high thermal conductivity and insulating properties. The thermally conductive insulating layer can be placed on the outside of the heating core 100, on the cavity wall of the mounting cavity 210, or filled in the space between the heating core 100 and the cavity wall of the mounting cavity 210 to insulate the heating core 100 and the heat-conducting component 200 without significantly affecting the thermal resistance.

[0043] When the heating element is inserted into the aerosol generating product 400, the outer surface of the heat-conducting component 200 will come into full contact with the aerosol generating product 400. The large contact area causes heat to concentrate in the contact area during heating, which can easily cause local overheating. This can lead to the aerosol matrix in the contact area burning and charring, producing a burnt taste and affecting the taste of the aerosol.

[0044] Please refer to Figure 1 A gas channel 220 is provided on the outer surface of the heat-conducting component 200, which helps to reduce the contact area between the heat-conducting component 200 and the aerosol generating product 400 through structural improvements. This helps to suppress the local heat flux density concentration phenomenon in the aerosol generating product 400, allowing the contact heat transfer surfaces to be spaced and dispersed. The parts around each contact heat transfer surface (such as the parts opposite to the gas channel 220) can disperse the heat absorbed on the contact heat transfer surface, thereby reducing the risk of overheating of each contact heat transfer surface and reducing the possibility of scorching.

[0045] Furthermore, the air guide channel 220 is used to heat the heat-conducting component 200 to generate a hot airflow, utilizing the convection of the hot airflow and the radiation of the channel wall of the air guide channel 220 to heat the aerosol-generating product 400. This helps to increase the contact area between the heating element and the surrounding airflow, and increase the airflow temperature, thereby compensating for the reduced heat conduction efficiency caused by the reduced contact area due to the air guide channel 220. Airflow convection also helps to accelerate the diffusion of heat to other areas inside the aerosol-generating product 400, thereby accelerating the spatial distribution of heat, improving heating efficiency and heating uniformity, and preventing premature and excessive release of volatile substances used to generate aerosols in the contact area and excessive residue in the non-contact area, achieving efficient and synchronous release of aerosols, and further ensuring the aerosol flavor.

[0046] In addition, the reduced heat conduction efficiency caused by setting the gas guide channel 220 will also keep the temperature of the heat conduction component 200 in a higher range during heating. The higher temperature helps to improve the heat radiation effect, which is beneficial to strengthen the heating of the part of the aerosol generating product 400 opposite to the gas guide channel 220, further improving the heating uniformity and heating efficiency, so as to quickly generate aerosol.

[0047] In a further embodiment, please refer to Figure 1 The heat-conducting component 200 may include a cylindrical section 230 and a conical tip section 240. The conical tip section 240 is used to guide the insertion of the cylindrical section 230 into the aerosol generating article 400. The gas guiding channel 220 may be disposed on the cylindrical section 230. The maximum outer diameter of the conical tip section 240 is not less than the outer diameter of the cylindrical section 230, which is used to restrict the aerosol matrix in the aerosol generating article 400 from entering the gas guiding channel 220 when the heating element is inserted into the aerosol generating article 400.

[0048] By setting the cone tip 240, it not only helps the heat-conducting component 200 to be inserted into the aerosol generating product 400, but also pushes the aerosol matrix in the aerosol generating product 400 away from the insertion area during the insertion process. This helps to prevent the aerosol matrix from blocking the gas guiding channel 220 and helps to maintain the effectiveness of the set gas guiding channel 220 structure.

[0049] For example, the cylindrical section 230 can be configured as a cylindrical structure, and the conical tip section 240 adopts a tapered structure, such as a conical or frustum-shaped structure. The conical tip section 240 is located at one end of the cylindrical section 230 along the axial direction. The maximum outer diameter of the conical tip section 240 can be equal to the outer diameter of the cylindrical section 230. The guide slope on the periphery of the conical tip section 240 can be precision machined, and the junction of the conical tip section 240 and the cylindrical section 230 is rounded to ensure that the heating element gradually fits the aerosol generating product 400 during insertion, which helps to avoid structural damage to the aerosol generating product 400 caused by local stress concentration.

[0050] The specific arrangement of the cylindrical section 230 and the conical tip section 240 is not limited, as long as it meets the design and usage requirements. For example, the cylindrical section 230 can also be set as a prism, and the conical tip section 240 can adopt a pyramid or frustum-shaped structure. If the radial dimension of the heat-conducting component 200 is small, the conical tip section 240 can be omitted, or the heat-conducting component 200 can be set as a cone, or a shape that is approximately cone or needle-shaped.

[0051] Furthermore, those skilled in the art will understand that the air guide channel 220 can be implemented in various ways to meet the needs of different heating scenarios.

[0052] In one embodiment, the air guide channel 220 can be a straight air guide channel 220 arranged parallel to the axial direction of the heat conductor 200; this configuration of the air guide channel 220 is conducive to establishing an axial air guide path and promoting the directional flow of hot air.

[0053] In another embodiment, the air guide channel 220 may also be a spiral groove arranged circumferentially around the heat conductor 200. The spiral configuration of the air guide channel 220 helps to form a circumferential air guide path, lengthens the airflow trajectory, enhances the heat diffusion effect, and can further reduce the contact area ratio.

[0054] In other embodiments, the air guide channel 220 can also be configured in other ways, such as wave-shaped or zigzag-shaped, as long as it meets the design and usage requirements. Furthermore, the various configurations of the air guide channel 220 can be set independently or in combination. For example, by combining an axially straight air guide channel 220 with a circumferentially spiral air guide channel 220, the combined effect of the heating element in guiding and heating in both the axial and radial directions can be enhanced.

[0055] In different embodiments, depending on the heating requirements, the air guide channel 220 may be provided with only one or at least two arranged around the heat conductor 200.

[0056] For example, at least two independent air channels 220 can be arranged symmetrically around the heat conductor 200. The parallel operation of multiple channels ensures heating uniformity and provides redundant backup paths for airflow. This allows other channels to maintain effective convection and radiation heating even when a single channel is blocked, thereby improving reliability.

[0057] Those skilled in the art will also understand that the air guide channel 220 can be formed directly on the outer surface of the heat-conducting component 200 by machining or etching, or an array of protrusions can be constructed on the surface using additive manufacturing technology, so that the gaps between adjacent protrusions naturally form the air guide channel 220. The air guide channel 220 has good compatibility with processing technology and is easy to process and shape.

[0058] For example, for a heat-conducting component 200 made of metal, grooves can be formed by mechanical cutting, chemical etching, or laser processing, which helps to precisely control the geometric parameters such as the width and depth of the grooves to regulate airflow. For a heat-conducting component 200 made of ceramic, protrusions can be constructed on the surface using additive manufacturing technology. The protruding structure forms the air-guiding channel 220, reducing the contact area while also helping to enhance the structural strength of the heat-conducting component 200, such as protrusions in the form of ribs.

[0059] In different embodiments, grooves or protrusions can be selected individually or combined, such as alternating arrangements of grooves and protrusions, to reduce the contact area while further increasing the airflow heat transfer area. Furthermore, the protrusions on the outer surface of the heat conductor 200 can be strip-shaped protrusions, columnar protrusions, or dots. When a concave dot array is used as the basic unit of the air guide channel 220, by arranging adjacent concave dots in an intersecting manner, a continuous, meandering composite groove structure can be formed. This helps to reduce the contact area while inducing airflow disturbance to enhance convective heat transfer and further improve heat transfer efficiency.

[0060] In one embodiment, the heat-conducting element 200 can be further divided into an insertion portion 250 and an exposed portion 260 to accommodate the heat exchange requirements between the contact interface of the aerosol generating article 400 and the external environment. The insertion portion 250 is inserted into the aerosol generating article 400, and the exposed portion 260 is exposed to the outside of the aerosol generating article 400. The air inlet channel 220 has an air inlet located in the exposed portion 260, allowing the air inlet of the air inlet channel 220 to directly communicate with the external environment, forming a natural convection inlet for ambient air to enter the interior of the aerosol generating article 400.

[0061] It is understandable that the air intake end of the air guide channel 220 can adopt a funnel-shaped diffuser structure to improve air intake efficiency through the inverse relationship between airflow velocity and pressure, i.e., Bernoulli's principle. Furthermore, the edges of the air intake end can be chamfered to reduce flow resistance.

[0062] To prevent the aerosol generating article 400 from being inserted too deeply, causing the air inlet end of the air guide channel 220 to also be inserted into the aerosol generating article 400, in one embodiment, please refer to... Figure 3 Alternatively, a mounting base 300 can be fitted onto the outside of the heat-conducting component 200. The mounting base 300 can be used for both mounting and positioning the heating element and for limiting the insertion depth of the aerosol generating product 400.

[0063] In another embodiment, a limiting protrusion may be provided on the surface of the heat-conducting element 200 to limit the insertion depth of the aerosol generating article 400. Furthermore, the limiting protrusion may be provided on the periphery of the air inlet end of each air guide channel 220 so that the heat dissipated by the limiting protrusion can be used for preheating the airflow, thereby improving thermal energy utilization.

[0064] In one embodiment, the outer surface of the heat-conducting element 200 may be covered with a radiation-emitting layer. The radiation-emitting layer has a higher emissivity than the heat-conducting element 200, thereby improving the overall thermal radiation effect of the heat-conducting element 200 and further enhancing the heating efficiency. The radiation-emitting layer may be a coating, plating, or other layer structure formed by other means.

[0065] Examples of the heating non-combustible device in this application:

[0066] In one embodiment, the heated non-combustible device includes an energy supply device and a heating element as described in any of the above embodiments. The energy supply device is used to supply energy to the heating element to stimulate the heating element to generate heat.

[0067] Those skilled in the art will understand that, depending on the heating principle of the heating core 100, the power supply component needs to provide the energy required by the heating core 100. For example, if the heating core 100 is a resistive core, the power supply component may include a battery cell or a collection of related components such as a battery cell and a circuit board to provide electrical energy to the heating core 100. If the heating core 100 is an electromagnetic induction core, the power supply component may also include an electromagnetic coil or other components capable of emitting an induced magnetic field to provide an induced magnetic field to the heating core 100, enabling the heating core 100 to generate heat through induced eddy currents.

[0068] In addition, the power supply component can also be used to support other functions of the heated non-combustible device, such as adjusting the heating power of the heating core 100 and displaying the status information of the heated non-combustible device.

[0069] For example, the power supply components may include a housing, a battery cell, and a circuit board. The housing can serve as the structural foundation of the heated non-combustible device, forming the main outer contour of the device and providing installation space for the battery cell, circuit board, and heating element. A bracket may be provided inside the housing, and the heating element can be mounted on the bracket via a mounting base 300. The housing may have a corresponding insertion port for the aerosol generating product 400, ensuring that the aerosol generating product 400 is precisely inserted into the heating element. A wire is connected to the heating element, electrically connecting it to the circuit board and the battery cell. The battery cell supplies power to the heating element and provides start / stop control and power regulation.

[0070] 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.
