Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, specifically to heating components and aerosol generation devices. Background Technology

[0002] An aerosol generating device is a device that heats an aerosol generating matrix to convert it into an inhalable aerosol. In related technologies, the aerosol generating matrix is ​​typically inserted into the outer casing of the aerosol generating device, and the aerosol is generated under the action of a heating element for the user to inhale.

[0003] Currently, heating components mainly adopt two forms: heating by wrapping the heating element around the substrate and heating by resistance wire or electromagnetic induction. Regardless of the heating method used, there is a problem of excessive radiation leakage, which results in a large amount of energy being lost through radiation and low heating efficiency. Utility Model Content

[0004] The purpose of this application is to provide a heating component and an aerosol generating device to improve the problem of excessive radiation leakage in current aerosol generating devices.

[0005] On one hand, this application provides a heating component for use in an aerosol generation device. The heating component includes a thermally conductive substrate and a conductive heating element. A heating cavity for heating the aerosol generation matrix is ​​formed inside the thermally conductive substrate. The conductive heating element is fixed to the thermally conductive substrate. A reflective layer is provided on the outer surface of the thermally conductive substrate.

[0006] In one embodiment, the conductive heating element is a resistive heating element for generating heat after being energized, and the reflective layer is a thermal radiation reflective layer for reflecting the thermal radiation emitted by the conductive heating element to the heating cavity.

[0007] In one embodiment, the reflective layer is an aluminum layer, a copper layer, or a silver layer.

[0008] In one embodiment, the conductive heating element includes an electromagnetic induction coil for generating an alternating magnetic field after being energized. The conductive heating element is configured to generate an alternating magnetic field after being energized. The reflective layer is an electromagnetic reflective layer, which is used to shield the electromagnetic radiation emitted by the electromagnetic induction coil to the outside of the heating cavity.

[0009] In one embodiment, the reflective layer is a ferrite layer or an aluminum layer.

[0010] In one embodiment, the element is embedded in and covered by the thermally conductive substrate, or the conductive heating element is disposed on the inner wall of the thermally conductive substrate and exposed in the heating cavity.

[0011] In one embodiment, the thermally conductive substrate is a ceramic body, and the thermally conductive substrate and the conductive heating element are integrally injection molded.

[0012] In one embodiment, the conductive heating element has a spiral structure, and there are multiple conductive heating elements, each of which is distributed in the heating assembly along the axial direction of the heat-conducting substrate.

[0014] On the other hand, embodiments of this application also provide an aerosol generating apparatus, including a heating component as described above and a housing, wherein the heating component is disposed within the housing.

[0015] According to the heating assembly in the above embodiments, by fixing the conductive heating element to the heat-conducting substrate and setting a reflective layer on the outer surface of the heat-conducting substrate, the radiation generated by the conductive heating element during operation is shielded or reflected back into the heating cavity of the heat-conducting substrate. This solves the problem of excessive radiation leakage in the prior art aerosol generating device. Applying the above heating assembly to the aerosol generating device can also solve the above problem. Attached Figure Description

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.

The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0025] The aerosol generating apparatus provided in this application embodiment is used to heat an aerosol generating matrix to generate aerosols for user use. The aerosol generating matrix can be in the form of a gel, paste, or solid. When the aerosol generating matrix is ​​solid, it can be in the form of pulverized, granulated, powdered, granular, strip-shaped, or flake-shaped solid. The aerosol generating matrix includes, but is not limited to, materials suitable for medical, health, and beauty purposes. For example, the aerosol generating matrix is ​​plant-based materials, such as plant roots, stems, leaves, flowers, buds, and seeds.

[0026] Please also refer to Figure 1 and Figure 2 This application provides a heating component 10, which can be applied to an aerosol generating device 1 and heats the aerosol generating matrix 2 inserted into the aerosol generating device 1 to generate aerosol.

[0027] The heating assembly 10 includes a thermally conductive substrate 110 and a conductive heating element 120. The thermally conductive substrate 110 has a heating cavity 111 formed inside for heating the aerosol generating matrix 2. The heating cavity 111 has an insertion port for inserting the aerosol generating matrix 2. The user can insert the aerosol generating matrix 2 into the heating cavity 111 through the insertion port, and under the heating action of the heating assembly 10, the aerosol generating matrix 2 is atomized to generate aerosol. The conductive heating element 120 is used to generate heat after being energized. It should be noted that the embodiments of this application do not limit the specific way in which the conductive heating element 120 generates heat. For example, in some embodiments, the conductive heating element 120 can be configured as a resistive heating element, such as a resistance wire or resistance sheet, for generating heat after being energized. When the conductive heating element 120 is energized, it can directly emit heat. For example, in some embodiments, the conductive heating element 120 may include an electromagnetic induction coil for generating an alternating magnetic field after being energized. When the electromagnetic induction coil is energized, it can generate an alternating magnetic field. In this embodiment, the electromagnetic induction coil needs to work with a metal component to generate heat through electromagnetic induction. It should be noted that the aforementioned metal component can be a metal component located inside the heating chamber 111 or a metal component located in the aerosol generating matrix 2. The conductive heating element 120 is also used to transfer heat to the heating chamber 111, thereby atomizing the aerosol generating matrix 2 located in the heating chamber 111 and generating an aerosol.

[0028] This application does not limit the specific structure and form of the thermally conductive substrate 110. For example, in one embodiment, the thermally conductive substrate 110 can be injection-molded ceramic and can be made of high-temperature resistant materials such as silicon dioxide, zirconium oxide, and glass to avoid or reduce damage caused by prolonged heating of the thermally conductive substrate 110. At the same time, it can transfer the heat generated by the conductive heating element 120 to the heating chamber 111 and maintain a high temperature in the heating chamber 111, thereby facilitating the atomization of the aerosol generation matrix 2.

[0029] In this embodiment, the thermally conductive substrate 110 can be configured as a cylindrical structure. It is understood that since most aerosol generating substrates 2 are rod-shaped, the configuration of the thermally conductive substrate 110 can make it compatible with most aerosol generating substrates 2, thereby improving the versatility of the thermally conductive substrate 110 and the versatility of the heating component 10 and the aerosol generating device 1.

[0030] As mentioned above, the internal space of the thermally conductive substrate 110 is the heating chamber 111, which facilitates the insertion of the aerosol generating matrix 2. In some other embodiments, the thermally conductive substrate 110 can be configured according to the specific structure of the aerosol generating matrix 2, for example, it can be configured as a square tube, etc., without limitation. For ease of explanation, the following description will take the thermally conductive substrate 110 configured as a cylindrical structure as an example.

[0031] This application does not limit the specific structure and form of the conductive heating element 120. For example, in one embodiment, the conductive heating element 120 can be a filament structure; in other embodiments, it can be a sheet structure; and in yet another embodiment, it can be a mesh structure. The specific design can be adjusted according to actual conditions and is not limited here. The conductive heating element 120 can be made of materials such as nickel 50, nickel-chromium-aluminum alloy, titanium, silver, or copper, so that it can quickly generate a high temperature after being energized and transfer the temperature to the heat-conducting substrate 110 and the heating cavity 111.

[0032] As mentioned above, in this embodiment, the thermally conductive substrate 110 is configured as a cylindrical structure, and the conductive heating element 120 can be configured as a spiral structure. This allows for a better match between the structures of the thermally conductive substrate 110 and the conductive heating element 120, thereby facilitating the uniform transfer of heat from the conductive heating element 120 to the thermally conductive substrate 110 after energization. Furthermore, in some other embodiments, the conductive heating element 120 can also be configured as a reciprocating bent structure. This also allows for a better match between the structures of the thermally conductive substrate 110 and the conductive heating element 120, thereby facilitating the uniform transfer of heat from the conductive heating element 120 to the thermally conductive substrate 110 after energization. The specific form adopted can be determined according to actual conditions and is not limited here.

[0033] Furthermore, the embodiments of this application do not limit the specific number of conductive heating elements 120. For example, in some embodiments, the number of conductive heating elements 120 can be set to one, and the end of the conductive heating element 120 can be flush with the end of the heat-conducting substrate 110, so that the heat-conducting substrate 110 can be heated more uniformly by the conductive heating element 120, thereby making the temperature in the heating chamber 111 more uniform, and thus making the atomization process of the aerosol generation matrix 2 located in the heating chamber 111 more uniform. Furthermore, the conductive heating element 120 can also be configured such that there is a distance between its end and the end of the heat-conducting substrate 110. It is understood that during the heating process of the heating assembly 10 heating the aerosol generating matrix 2, the main heat is concentrated in the middle of the heating chamber 111. Therefore, the above-mentioned configuration of the conductive heating element 120 can reduce the amount of heat transferred to the end of the heat-conducting substrate 110, thereby facilitating the conductive heating element 120 to transfer more heat to the middle of the heat-conducting substrate 110, i.e., the heating chamber 111, thereby improving the energy utilization rate.

[0034] In other embodiments, for example, the number of conductive heating elements 120 can be set to multiple, such as two, three, or four, depending on the actual situation, and is not limited here. Each conductive heating element 120 is distributed along the axial direction of the heat-conducting substrate 110 in the heating assembly 10. This allows the heat-conducting substrate 110 to be heated more uniformly by the conductive heating elements 120, thereby promoting more uniform temperature within the heating chamber 111 and making the atomization process of the aerosol generating matrix 2 within the heating chamber 111 more uniform. When the number of conductive heating elements 120 is greater than two, the distance between adjacent conductive heating elements 120 can be set to be the same, which further promotes temperature uniformity within the heating chamber 111 and makes the atomization process of the aerosol generating matrix 2 within the heating chamber 111 more uniform.

[0035] Furthermore, in this embodiment, each conductive heating element 120 can be individually controlled, thereby enabling more precise control of the temperature within the heating cavity 111. It is understood that since both ends of the heating cavity 111 are connected to the outside, heat is more easily lost from the ends of the heating cavity 111 compared to the middle, resulting in a lower temperature at both ends compared to the middle. Therefore, the power of the conductive heating elements 120 located at both ends of the heat-conducting substrate 110 can be set to be greater than the power of the conductive heating elements 120 located in the middle of the heat-conducting substrate 110, thereby enabling the conductive heating elements 120 at both ends of the heat-conducting substrate 110 to generate more heat to compensate for the heat loss from both ends of the heating cavity 111 to the outside.

[0036] Furthermore, since the main heating position of the heating chamber 111 for the aerosol generation matrix 2 is located in the middle of the heating chamber 111, another embodiment is provided here, which is different from the previous embodiment. In this embodiment, the power of the conductive heating element 120 located in the middle of the heat-conducting substrate 110 can be set to be greater than the power of the conductive heating elements 120 at both ends of the heat-conducting substrate 110. This allows the conductive heating elements 120 at both ends of the heat-conducting substrate 110 to mainly play the role of heat preservation inside the heating chamber 111, while the conductive heating element 120 located in the middle of the heat-conducting substrate 110 mainly plays the role of heating inside the heating chamber 111 and atomizing the aerosol generation matrix 2. This can help improve the energy utilization rate.

[0037] In this embodiment, the conductive heating element 120 and the thermally conductive substrate 110 can be integrally formed, which makes the connection between the conductive heating element 120 and the thermally conductive substrate 110 more secure and stable, avoiding or reducing the risk of the conductive heating element 120 and the thermally conductive substrate 110 falling off each other due to thermal expansion and contraction during long-term operation.

[0038] Furthermore, in one embodiment, the conductive heating element 120 and the heat-conducting substrate 110 can be integrally injection molded. It is understood that in the aerosol generating device 1, the internal space is relatively limited, so the size of the heating component 10 is usually small. By adopting the integral injection molding method, the size of the conductive heating element 120 and the heat-conducting substrate 110 can be further reduced, thereby making the heating component 10 more suitable for the aerosol generating device 1.

[0039] It should be noted that the embodiments of this application do not limit the specific positions of the conductive heating element 120 and the thermally conductive substrate 110. For example, in some embodiments, the conductive heating element 120 can be disposed on the inner wall of the thermally conductive substrate 110 and exposed in the heating chamber 111. This allows the conductive heating element 120 to be directly located in the heating chamber 111, and when the aerosol generating matrix 2 is located in the heating chamber 111, it can be heated more quickly by the conductive heating element 120, thereby improving the atomization speed of the aerosol generating matrix 2.

[0040] In this embodiment, the conductive heating element 120 can also be disposed inside the thermally conductive substrate 110. Specifically, the conductive heating element 120 can be embedded in the thermally conductive substrate 110 and covered by the thermally conductive substrate 110. Although in this embodiment, the heat generated by the conductive heating element 120 needs to pass through the thermally conductive substrate 110 before being transferred to the heating chamber 111, compared with the previous embodiment, the heating component 10 of this embodiment has a slower atomization speed of the aerosol generating matrix 2. However, since the conductive heating element 120 is disposed inside the thermally conductive substrate 110, the conductive heating element 120 will not be in direct contact with the air, thereby reducing the heat directly dissipated into the air by the conductive heating element 120, which is beneficial to improving energy utilization.

[0041] Furthermore, in this embodiment, a reflective layer 130 is provided around the thermally conductive substrate 110. The reflective layer 130 can be used to reflect or shield the radiation generated by the conductive heating element 120 to the outside of the heating cavity 111. It should be noted that the aforementioned radiation can be thermal radiation or electromagnetic radiation, and the specific type can be limited according to the specific form of the conductive heating element 120.

[0042] For example, in one embodiment, the conductive heating element 120 is a resistance wire, and the conductive heating element 120 is configured to generate heat after being energized. In this embodiment, the reflective layer 130 is a heat radiation reflective layer 130. Since the emissivity of the heat-conducting substrate 110 is relatively low, the heat radiation generated by the heating of the conductive heating element 120 will dissipate outward through the heat-conducting substrate 110, resulting in high temperature and high power consumption of the outer shell 20 of the aerosol generating device 1. Therefore, the heat radiation reflective layer 130 can be used to reflect the heat radiation emitted by the conductive heating element 120 to the heating cavity 111, thereby improving the energy utilization rate. At the same time, it can avoid or reduce the leakage of heat radiation emitted by the conductive heating element 120 to the outer shell 20 of the aerosol generating device 1, thereby avoiding or reducing the problem of users getting burned during use. Furthermore, in this embodiment, the reflective layer 130 can be made of a material with low emissivity, such as an aluminum layer, a copper layer, or a silver layer, etc., which can be set according to the actual situation.

[0043] For example, in another embodiment, the conductive heating element 120 is an electromagnetic induction coil, configured to generate an alternating magnetic field when energized. In this embodiment, the reflective layer 130 is an electromagnetic reflective layer 130, used to shield the electromagnetic radiation emitted by the conductive heating element 120 to the outside of the heating cavity 111. It is understood that in this embodiment, the conductive heating element 120 needs to cooperate with a metal component, which can be disposed within the heating cavity 111 or within the aerosol generating matrix 2. When the metal component is disposed within the heating cavity 111, the conductive heating element 120 generates an alternating magnetic field upon energization, working in conjunction with the metal component to heat the heating cavity 111. When the metal component is disposed within the aerosol generating matrix 2, and when the aerosol generating matrix 2 is located within the heating cavity 111, the metal component inside the aerosol generating matrix 2 can cooperate with the conductive heating element 120 to generate electromagnetic induction, thereby generating heat to heat the aerosol generating matrix 2. However, since the electromagnetic field generated by the conductive heating element 120 after being energized emits electromagnetic radiation, causing electromagnetic pollution and energy loss, in this embodiment, the electromagnetic reflection layer 130 can be used to reflect the electromagnetic radiation emitted by the conductive heating element 120 back to the heating cavity 111, thereby improving energy utilization. Furthermore, in this embodiment, the reflection layer 130 can be made of a material with high magnetic permeability, such as nickel-chromium-aluminum alloy, titanium, silver, or copper, etc., and can be specifically configured according to actual conditions.

[0044] It should be noted that the embodiments of this application do not limit the specific setting method of the reflective layer 130. For example, in one embodiment, the reflective layer 130 can be set on the periphery of the heat-conducting substrate 110 by coating. In another embodiment, the reflective layer 130 can be set on the periphery of the heat-conducting substrate 110 by pasting. The specific setting can be made according to the actual situation and is not limited here.

[0045] In one embodiment, the heating assembly 10 may further include a lead 140, which can be electrically connected to the conductive heating element 120 to transfer energy to the conductive heating element 120. The lead 140 can pass through and exit the thermally conductive substrate 110, and be electrically connected to the battery in the aerosol generating device 1. This application does not limit the specific number of leads 140; as mentioned above, the number can be adjusted according to the number of conductive heating elements 120.

[0046] Furthermore, the specific material of the lead wire 140 is not limited in the embodiments of this application. For example, in one embodiment, the lead wire 140 may be made of the same material as the conductive heating element 120. The specific details can be found in the description of the conductive heating element 120 above, which will not be repeated here.

[0047] In summary, the heating assembly 10 provided in this application embodiment solves the problem of radiation leakage that easily occurs in the aerosol generating device 1 in the prior art by setting the conductive heating element 120 to be integrally formed with the heat-conducting substrate 110 and setting a reflective layer 130 on the periphery of the heat-conducting substrate 110, and using the reflective layer 130 to shield or reflect the radiation generated by the conductive heating element 120 during operation back into the heating cavity 111 of the heat-conducting substrate 110.

[0048] Please see Figure 3 This application embodiment also provides an aerosol generating device 1, which includes a heating component 10 as described above and a housing 20. The heating component 10 is disposed inside the housing 20, and the aerosol generating device 1 may further include a battery 30 disposed inside the housing 20. The battery 30 can be electrically connected to the heating component 10 to provide energy to the heating component 10. Specifically, the battery 30 can be electrically connected to a lead wire 140 so that the lead wire 140 transfers energy to the conductive heating element 120.

[0049] The following describes the working principle of the aerosol generating device 1 provided in the embodiments of this application. For ease of explanation, the following description will take the conductive heating element 120 as a resistance wire as an example:

[0050] The user can load the aerosol generating matrix 2 into the heating chamber 111 of the heating component 10 in the aerosol generating device 1, and then start the heating component 10. With the start of the heating component 10, the battery 30 transfers energy to the conductive heating element 120 via the lead wire 140. The conductive heating element 120 generates heat after being energized and transfers the heat to the thermally conductive substrate 110 and the heating chamber 111, thereby heating the aerosol generating matrix 2 within the heating chamber 111 and causing it to atomize to generate aerosols. During this process, the heat generated by the conductive heating element 120 will be lost to the outside of the heating chamber 110. When the heat comes into contact with the reflective layer 130 surrounding the thermally conductive substrate 110, the heat will be reflected back into the heating chamber by the reflective layer 130, and then used to continue heating the aerosol generating device 2. Furthermore, due to the reflective effect of the reflective layer 130, the heat lost in the aforementioned process will not flow to the outer shell of the aerosol generating device 1, or very little of the heat lost in the aforementioned process will flow to the outer shell of the aerosol generating device. When the user holds the outer shell of the aerosol generating device 1 and performs the aerosol inhalation operation, the user will not feel hot, which is beneficial to improving the user's inhalation experience.

[0051] The following example illustrates the process using a conductive heating element that specifically includes an electromagnetic induction coil, with a metal component disposed within the aerosol generating matrix 2:

[0052] The user can load the aerosol generating matrix 2 into the heating chamber 111 of the heating component 10 in the aerosol generating device 1, and then start the heating component 10. With the start of the heating component 10, the battery 30 transfers energy to the conductive heating element 120 through the lead 140. The conductive heating element 120 generates an alternating magnetic field after being energized. Since the aerosol generating matrix 2 is located inside the heating chamber 111, the metal components in the aerosol generating matrix 2 will undergo electromagnetic induction with the alternating magnetic field generated by the conductive heating element 120, thereby generating heat to heat the aerosol generating matrix 2 and cause it to atomize and generate aerosols. During this process, the alternating magnetic field generated by the conductive heating element 120 will radiate outwards from the heating chamber 110. When the magnetic field radiated outwards from the heating chamber 110 comes into contact with the reflective layer 130 surrounding the conductive matrix 110, the radiated magnetic field will be reflected back into the heating chamber by the reflective layer 130, and then continue to be used to heat the aerosol generating device 2. Furthermore, due to the reflective effect of the reflective layer 130, the magnetic field radiated outward in the aforementioned process will not flow to the outer shell of the aerosol generating device 1, or the heat lost in the aforementioned process will rarely flow to the outer shell of the aerosol generating device, thereby avoiding or reducing electromagnetic pollution.

[0053] In summary, since the aerosol generating device 1 uses the heating component 10 described above, the aerosol generating device 1 provided in this application embodiment also solves the problem of radiation leakage that easily occurs in the prior art aerosol generating device 1.

[0054] 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.
