Abstract
Description
Technical Field
[0001] This application belongs to the field of atomization technology, and more specifically, relates to a heating component and an aerosol generating device. Background Technology
[0002] The aerosol generation device uses heating elements to heat the aerosol matrix, atomizing it into aerosols for use. By heating the aerosol matrix in stages, the device can produce different atomization effects on different parts of the aerosol matrix.
[0003] In related technologies, aerosol generating devices use different heating components to heat the aerosol matrix in stages and independently control the heating power of different heating components, resulting in a complex structure and increased manufacturing difficulty. Utility Model Content
[0004] The purpose of this application is to provide a heating component and an aerosol generating device to solve the technical problems of complex structure and increased manufacturing difficulty in the prior art.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, this application provides a heating assembly for heating an aerosol matrix, the aerosol matrix comprising a first part and a second part. The heating assembly includes a heating tube and an auxiliary heating component. The heating tube includes a first heating section and a second heating section. The first heating section is used to accommodate and heat the first part. The second heating section is connected to one axial end of the first heating section. The auxiliary heating component is disposed on the inner circumferential side of the second heating section and is thermally connected to the second heating section. The auxiliary heating component is used to accommodate and heat the second part. The auxiliary heating component includes a first heating state and a second heating state. In the first heating state, the auxiliary heating component is spaced apart from the inner circumferential surface of the second heating section on its side near the second heating section. In the second heating state, the auxiliary heating component is in contact with the inner circumferential surface of the second heating section on its side near the second heating section.
[0007] Through the above technical solution, the heating assembly provided in this application does not require adjustment of the heating power of the auxiliary heating component. The heating efficiency of the second part of the aerosol matrix can be adjusted by regulating the heating state of the auxiliary heating component. Specifically, compared to the first heating state, the auxiliary heating component exhibits higher heating efficiency for the second part of the aerosol matrix in the second heating state. This simplifies the structure of the heating assembly and reduces manufacturing difficulty, at least to some extent.
[0008] Therefore, the heating component provided in this application helps to solve the technical problems of complex structure and increased manufacturing difficulty.
[0009] In some embodiments, the auxiliary heating component includes a deformable component that deforms in response to temperature changes, thereby switching the auxiliary heating component between a first heating state and a second heating state.
[0010] In this way, the deformable component itself can deform according to temperature changes, thereby adjusting the heating state, which helps to reduce control logic and thus reduce manufacturing difficulty.
[0011] In some embodiments, the heating assembly further includes a first limiting component and a second limiting component, which are disposed on the inner circumferential side of the second heating section and spaced apart along the axial direction of the second heating section, and the deformable component is located between the first limiting component and the second limiting component.
[0012] In this way, the deformable component can undergo radial deformation under the limitation of the first limiting component and the second limiting component, thereby switching between the first heating state and the second heating state.
[0013] In some embodiments, at least one of the first limiting member and the second limiting member is an annular ring extending circumferentially along the second heating section; and / or, at least one of the first limiting member and the second limiting member is integrally connected to the second heating section; and / or, the deformable member abuts against the first limiting member and the second limiting member respectively.
[0014] In this way, the heating assembly provided by this application can improve the limiting effect of the first and second limiting components on the deformable component. Furthermore, the fact that at least one of the first and second limiting components is integrally connected to the second heating section can reduce the manufacturing difficulty of the heating assembly.
[0015] In some embodiments, the deformable component includes multiple deformable plates arranged sequentially along the circumference of the second heating section.
[0016] In this way, the deformable plates can heat multiple locations circumferentially on the second part of the aerosol matrix, which improves the heating effect. Furthermore, the gap between adjacent deformable plates can accommodate the second part of the aerosol matrix, further enhancing the heating effect. In addition, the deformable plates can be used independently; the failure of a single deformable plate does not affect the performance of the others, thus improving reliability.
[0017] In some embodiments, the deformable component includes a reducing tube. This allows the deformable component to heat any position circumferentially on the second portion of the aerosol matrix, which improves the heating effect.
[0018] In some embodiments, the reducing pipe is coaxially arranged with the second heating section; and / or, the first heating section is coaxially arranged with the second heating section; and / or, the outer periphery of the reducing pipe's cross-section is circular, elliptical, or polygonal, and the reducing pipe's cross-section is perpendicular to the reducing pipe's axial direction.
[0019] In this way, the reducing tube can be manufactured using the same reference as the second heating section, which helps reduce manufacturing difficulty. In addition, the outer perimeter of the reducing tube's cross-section can be circular, elliptical, or polygonal, and the shape of the reducing tube can be specifically set according to product requirements, making it highly adaptable.
[0020] In some embodiments, the deformable component is made of a two-way shape memory alloy, a two-way shape memory ceramic, or a two-way shape memory polymer. This allows the deformable component to repeatedly switch between a first heating state and a second heating state, which helps to improve its service life.
[0021] In some embodiments, the deformable component includes a first layer and a second layer. Compared to the second layer, the first layer is closer to the inner wall of the second heating section, and the first layer is more prone to deformation under temperature changes. This way, when the auxiliary heating component is in the first heating state, the side of the auxiliary heating component closer to the second heating section is more likely to contact the inner circumferential surface of the second heating section, which helps improve reliability.
[0022] In some embodiments, the auxiliary heating component includes multiple movable plates arranged sequentially along the circumference of the second heating section. The movable plates are used to move radially along the second heating section to switch between a first heating state and a second heating state. This allows the movable plates to switch between the first and second heating states through their own movement, reducing control logic and thus lowering manufacturing complexity.
[0023] In some embodiments, the heating assembly provided in this application further includes a guide member, which is disposed in one of the movable plate and the second heating section. The other of the movable plate and the second heating section has a guide hole, through which the guide member passes. The movable plate can move axially along the guide member or the guide hole, which helps to avoid misalignment of the movable plate and thus improves the heating effect.
[0024] In some embodiments, the inner circumferential surface of the second heating section is provided with a smooth coating, and when the auxiliary heating component is in the second heating state, the auxiliary heating component is in contact with the smooth coating near the side of the second heating section; and / or, the first heating section and the second heating section are integrally connected.
[0025] This design prevents the auxiliary heating components from easily adhering to the second heating section, allowing for better reliability between the first and second heating states. Furthermore, when the first and second heating sections are integrally connected, the heating element has a one-piece molded structure, simplifying manufacturing.
[0026] Secondly, this application provides an aerosol generating apparatus, including the heating component of the above-described embodiments. The aerosol generating apparatus provided by this application has the same or similar technical effects as the heating component of the above-described embodiments, and will not be described in detail here.

[0050] The aerosol generating device uses heating to atomize the aerosol matrix 200 into aerosols without combustion, allowing for the utilization of the generated aerosols. The applications of the aerosol generating device are not listed here. The aerosol generating device primarily generates heat through the heating element 100, which is then transferred to the aerosol matrix 200, causing it to atomize and form aerosols.
[0051] Optionally, the aerosol generating device can supply electrical energy to the heating component 100 via a power source, and the heating component 100 can generate heat after being powered on.
[0052] The aerosol generating device can produce different atomization effects on different parts of the aerosol matrix 200 by segmenting the heating. In related technologies, aerosol generating devices use different heating components to heat the aerosol matrix 200 in segments and independently control the heating power of different heating components, resulting in a complex structure and increased manufacturing difficulty.
[0053] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 To address the aforementioned problems, embodiments of this application provide a heating assembly 100 for heating an aerosol matrix 200, the aerosol matrix 200 comprising a first portion 210 and a second portion 220. Optionally, the radial dimension of the first portion 210 is larger than the radial dimension of the second portion 220.
[0054] The heating assembly 100 provided in this embodiment includes a heating tube 10, which includes a first heating section 11 for accommodating and heating a first portion 210. The first portion 210 of the aerosol matrix 200 fills the inner cavity of the first heating section 11 and contacts the inner circumferential surface of the first heating section 11. Optionally, the first portion 210 of the aerosol matrix 200 is in contact with the inner circumferential surface of the first heating section 11. Optionally, the first portion 210 of the aerosol matrix 200 abuts against the inner circumferential surface of the first heating section 11.
[0055] The heating tube 10 also includes a second heating section 12, which is connected to one axial end of the first heating section 11. Optionally, the second heating section 12 is integrally connected to the first heating section 11, that is, the heating tube 10 is a one-piece molded structure, which facilitates the manufacturing of the heating tube 10.
[0056] The heating assembly 100 provided in this embodiment further includes an auxiliary heating component 20, which is disposed on the inner circumferential side of the second heating section 12 and is thermally connected to the second heating section 12. In this way, the second heating section 12 can transfer heat to the auxiliary heating component 20.
[0057] The auxiliary heating component 20 is used to accommodate and heat the second part 220. The auxiliary heating component 20 includes a first heating state and a second heating state. (See also...) Figure 2 and Figure 4 In the first heating state, the auxiliary heating component 20 is positioned with its side near the second heating section 12 spaced apart from the inner circumferential surface of the second heating section 12. (See also...) Figure 3 , Figure 5 and Figure 6 When the auxiliary heating component 20 is in the second heating state, the side of the auxiliary heating component 20 near the second heating section 12 contacts the inner circumferential surface of the second heating section 12.
[0058] Optionally, the side of the auxiliary heating component 20 near the second heating section 12 is in contact with the inner peripheral surface of the second heating section 12. Alternatively, the side of the auxiliary heating component 20 near the second heating section 12 abuts against the inner peripheral surface of the second heating section 12.
[0059] Through the above technical solution, the heating component 100 provided in this application embodiment does not require adjustment of the heating power of the auxiliary heating component 20. The heating efficiency of the second part 220 of the aerosol matrix 200 can be adjusted by adjusting the heating state of the auxiliary heating component 20. Specifically, compared with the first heating state, the auxiliary heating component 20 has a higher heating efficiency for the second part 220 of the aerosol matrix 200 in the second heating state. This is beneficial to at least to some extent simplifying the structure of the heating component 100 and reducing manufacturing difficulty.
[0060] Therefore, the heating component 100 provided in this application embodiment helps to solve the technical problems of complex structure and increased manufacturing difficulty.
[0061] Understandably, please refer to Figure 3 , Figure 5 and Figure 6 When the auxiliary heating component 20 is in the second heating state, the second portion 220 of the aerosol matrix 200 can deform, and the radial dimension of the second portion 220 of the aerosol matrix 200 increases. The outer peripheral surface of the second portion 220 of the aerosol matrix 200 can either contact the auxiliary heating component 20 or be spaced apart from it.
[0062] When the outer peripheral surface of the second part 220 of the aerosol matrix 200 is spaced apart from the auxiliary heating component 20, the auxiliary heating component 20 can radiate heat to the second part 220 of the aerosol matrix 200, thereby heating the second part 220 of the aerosol matrix 200.
[0063] It should be noted that, compared to the distance between the auxiliary heating component 20 and the second heating section 12 in the first heating state, the distance between the outer peripheral surface of the second portion 220 of the aerosol matrix 200 and the auxiliary heating component 20 is smaller in the second heating state. Therefore, compared to the first heating state, the auxiliary heating component 20 has a higher heating efficiency for the second portion 220 of the aerosol matrix 200 in the second heating state.
[0064] In some embodiments, the auxiliary heating component 20 includes a deformable component for deforming in response to temperature changes, thereby switching the auxiliary heating component 20 between a first heating state and a second heating state.
[0065] In this way, the deformable component itself can deform according to temperature changes, thereby adjusting the heating state, which helps to reduce control logic and thus reduce manufacturing difficulty.
[0066] When the temperature of the deformable component reaches the preset temperature, the deformable component expands and deforms, and the deformable component can switch between the first heating state and the second heating state.
[0067] Optionally, the expansion ratio of the deformable component is greater than or equal to 4% and less than or equal to 12%. Optionally, the expansion ratio of the deformable component is greater than or equal to 6% and less than or equal to 12%.
[0068] The preset temperature is greater than or equal to 200℃ and less than or equal to 300℃.
[0069] Optionally, the deformable component can be made of a two-way shape memory alloy, a two-way shape memory ceramic, or a two-way shape memory polymer. This allows the deformable component to repeatedly switch between a first heating state and a second heating state, which helps to improve its service life.
[0070] Optionally, the deformable component can be made of an iron-based shape memory alloy (Fe-based SMA). This allows the component to deform within a temperature range of 200°C to 300°C, with the deformation effectively recovered, exhibiting good mechanical properties and high-temperature stability. Optionally, the deformation is greater than or equal to 4% and less than or equal to 6%.
[0071] Optionally, the deformable component can be made of a copper-aluminum-zinc alloy (Cu-Al-Zn). This allows the deformable component to deform within a temperature range of 200°C to 300°C, and the deformation can be effectively recovered, exhibiting good mechanical properties and high-temperature stability. Optionally, the deformation is greater than or equal to 5% and less than or equal to 10%. Optionally, the deformation is greater than or equal to 5% and less than or equal to 8%.
[0072] Optionally, the deformable component can be made of a copper-zinc alloy (Cu-Zn). This allows the component to deform within a temperature range of 200°C to 300°C, and the deformation can be effectively recovered, exhibiting good mechanical properties and high-temperature stability. Optionally, the deformation is greater than or equal to 6% and less than or equal to 8%.
[0073] Please continue reading Figure 2 , Figure 3 and combined Figure 7 In some embodiments, the deformable component includes a reducing tube. This allows the deformable component to heat any position circumferentially on the second portion 220 of the aerosol matrix 200, which improves the heating effect.
[0074] Optionally, the reducing pipe is coaxially arranged with the second heating section 12.
[0075] Optionally, the first heating section 11 and the second heating section 12 are arranged coaxially.
[0076] In this way, the reducing tube can be manufactured using the same reference as the second heating section 12, which helps to reduce manufacturing difficulty.
[0077] Optionally, the outer periphery of the cross-section of the reducer is circular, that is, the reducer is a circular pipe.
[0078] Optionally, please refer to Figure 8 The outer perimeter of the cross-section of the reducing pipe is elliptical, that is, the reducing pipe is an elliptical pipe.
[0079] Optionally, please refer to Figure 9 The outer perimeter of the cross-section of a reducer is polygonal; that is, a reducer is a polygonal pipe. For example, the outer perimeter of the cross-section of a reducer is quadrilateral.
[0080] Understandably, the shape of the reducer can be customized according to product requirements, making it highly adaptable.
[0081] Please see Figure 10 In some embodiments, the deformable component includes a first layer 21 and a second layer 22. Compared to the second layer 22, the first layer 21 is closer to the inner wall of the second heating section 12, and the first layer 21 is more prone to deformation under temperature changes. In this way, when the auxiliary heating component 20 is in the first heating state, the side of the auxiliary heating component 20 near the second heating section 12 is more likely to contact the inner circumferential surface of the second heating section 12, which helps to improve reliability.
[0082] Please refer to the following: Figure 11 and Figure 12 In some embodiments, the deformable component includes multiple deformable plates arranged sequentially along the circumference of the second heating section 12.
[0083] In this way, the deformable plates can heat multiple locations circumferentially on the second portion 220 of the aerosol matrix 200, which improves the heating effect. Furthermore, the gap 201 between adjacent deformable plates can accommodate the second portion 220 of the aerosol matrix 200, further enhancing the heating effect. In addition, the deformable plates can be used independently; the failure of a single deformable plate does not affect the performance of the others, thus improving reliability.
[0084] Please refer to the following: Figure 12 , Figure 13 and Figure 14In some embodiments, the auxiliary heating component 20 includes multiple movable plates arranged sequentially along the circumference of the second heating section 12. The movable plates are used to move radially along the second heating section 12 to switch the auxiliary heating component 20 between a first heating state and a second heating state. This allows the movable plates to switch between the first and second heating states through their own movement, reducing control logic and thus lowering manufacturing complexity. It is understood that the gap 201 between adjacent movable plates can also accommodate the second portion 220 of the aerosol matrix 200, which is beneficial for improving the heating effect.
[0085] Please continue reading Figure 13 and Figure 14 In some embodiments, the heating assembly 100 provided in this application further includes a guide member 50. The guide member 50 is disposed in one of the movable plate and the second heating section 12, and the other of the movable plate and the second heating section 12 is provided with a guide hole 60, through which the guide member 50 passes. In this way, the movable plate can move along the axial direction of the guide member 50 or the guide hole 60, which helps to avoid misalignment of the movable plate and thus helps to improve the heating effect.
[0086] Optionally, please refer to Figure 13 The guide member 50 is disposed in the second heating section 12, and the guide hole 60 is disposed in the movable plate. In this way, the movable plate can move along the guide member 50.
[0087] Optionally, please refer to Figure 14 A guide member 50 is provided on the guide member 50, and a guide hole 60 is provided on the second heating section 12. In this way, the moving plate can move along the axial direction of the guide hole 60.
[0088] Please refer to the following: Figure 2 , Figure 3 , Figure 11 , Figure 13 , Figure 14 , Figure 15 and Figure 16 In some embodiments, the heating assembly 100 provided in this application further includes a first limiting component 30 and a second limiting component 40. The first limiting component 30 and the second limiting component 40 are disposed on the inner circumferential side of the second heating section 12 and are spaced apart along the axial direction of the second heating section 12. The deformable component is located between the first limiting component 30 and the second limiting component 40.
[0089] In this way, the deformable component can undergo radial deformation under the limitation of the first limiting component 30 and the second limiting component 40, thereby switching between the first heating state and the second heating state.
[0090] Optionally, at least one of the first limiting member 30 and the second limiting member 40 is integrally connected to the second heating section 12. This can reduce the manufacturing difficulty of the heating assembly 100.
[0091] For example, the first limiting component 30 is integrally connected to the second heating section 12.
[0092] For example, the second limiting component 40 is integrally connected to the second heating section 12.
[0093] For example, the first limiting component 30 and the second limiting component 40 are both integrally connected to the second heating section 12.
[0094] Optionally, the deformable component abuts against the first limiting component 30 and the second limiting component 40, respectively. In this way, the heating assembly 100 provided in this embodiment can improve the limiting effect of the first limiting component 30 and the second limiting component 40 on the deformable component.
[0095] Please refer to the following: Figure 2 , Figure 3 , Figure 11 , Figure 13 , Figure 14 and Figure 15 Optionally, there are multiple first limiting components 30, and the multiple first limiting components 30 are arranged at intervals along the circumference of the second heating section 12.
[0096] Optionally, there are multiple second limiting components 40, and the multiple second limiting components 40 are arranged at intervals along the circumference of the second heating section 12.
[0097] Please see Figure 16 In some embodiments, at least one of the first limiting member 30 and the second limiting member 40 is an annular shape extending circumferentially along the second heating section 12. In this way, the heating assembly 100 provided in this application embodiment can improve the limiting effect of the first limiting member 30 and the second limiting member 40 on the deformable member.
[0098] Optionally, the first limiting member 30 is an annular shape extending circumferentially along the second heating section 12.
[0099] Optionally, the second limiting member 40 is an annular shape extending circumferentially along the second heating section 12.
[0100] In some embodiments, the inner peripheral surface of the second heating section 12 is provided with a smooth coating (not shown in the figure), and the auxiliary heating component 20 is in contact with the smooth coating near the side of the second heating section 12 when the auxiliary heating component 20 is in the second heating state.
[0101] Optionally, the auxiliary heating component 20 is in contact with and adheres to the smooth coating on the side near the second heating section 12.
[0102] Optionally, the auxiliary heating component 20 is in contact with the smooth coating on the side near the second heating section 12.
[0103] In this way, the auxiliary heating component 20 is less likely to stick to the second heating section 12, thus improving the reliability of use between the first heating state and the second heating state.
[0104] Alternatively, the smooth coating may be a graphite coating, graphene coating, diamond-like carbon coating, diamond coating, or other low-friction coefficient coating.
