Abstract
Description
Technical Field
[0001] This application relates to the field of atomization device technology, and in particular to an aerosol generating device and a heating component. Background Technology
[0002] Aerosol generating devices are used to generate aerosols for users to inhale. Current aerosol generating devices require a heating element, which, when energized, heats the aerosol matrix, producing aerosols. Current heating elements typically use heating meshes. To improve the heating rate of the mesh, it is usually made of a metal with low resistivity, such as titanium. Electrode wires are used to connect the heating element to the power supply components, and the heating element and electrode wires are usually welded together. For weld stability, nickel wire is typically used to weld to the titanium mesh. However, due to the high resistivity of nickel wire, current nickel wires are relatively thick to reduce resistance, making them difficult to bend during welding and causing inconvenience in wiring. Using wires with lower resistivity, such as copper wire, results in smaller electrode wire diameters that are easier to bend, but the welding reliability of copper wire to titanium mesh is poor. In summary, current electrode wires have poor compatibility with the heating element, resulting in poor adaptability. Utility Model Content

[0035] To address the problem of poor adaptability of electrode wires in current aerosol generating devices to heating elements, the heating component of this application adopts a novel electrode wire design. The electrode wire comprises a first segment and a second segment, which are separately configured. This allows the first and second segments to be made of different materials as needed, resulting in better compatibility with the heating element. The heating component of the aerosol generating device of this application will be further described below with reference to the accompanying drawings.
[0036] In one embodiment, the aerosol generating device includes a power supply component and a heating component, wherein the power supply component supplies power to the heating component. In another embodiment, the power supply component includes a power source and a circuit board, and the heating component is electrically connected to the circuit board.
[0037] In one embodiment, please refer to Figure 1 and Figure 2 The heating component includes a heating element 1 and electrode wires 2. The heating element 1 is used to heat the aerosol generation matrix. The electrode wires 2 include a first segment 21 and a second segment 22. The first segment 21 is welded to the heating element 1, and the connection between the first segment 21 and the heating element 1 is covered with an anti-corrosion layer 23. The second segment 22 is separately disposed from the first segment 21 but electrically connected, and the second segment 22 is used to conduct electricity to the power supply component of the aerosol generation device. It should be noted that in this application, the separate disposal of the second segment 22 and the first segment 21 means that the first segment 22 and the second segment 21 are connected together by a subsequent connection method, rather than being integrally formed.
[0038] Because the first segment 21 and the second segment 22 are separately configured, they can be made of different materials and have different sizes as needed. The anti-corrosion layer 23 covering the first segment 21 can protect it and reduce corrosion from aerosols or other oils in the aerosol generating device. The conductive connection between the first segment 21 and the second segment 22 allows the electrode wire 2 to be connected to the power supply component through the second segment 22.
[0039] Regarding the connection method between the first line segment 21 and the second line segment 22, the first line segment 21 and the second line segment 22 can be connected together in any feasible way, including detachable connection and non-detachable connection. Detachable connection includes snap-fit, fastener connection, crimping, etc., while non-detachable connection includes welding, riveting, etc.
[0040] In one embodiment, please refer to Figure 1 and Figure 2 The resistivity of the second segment 22 is lower than that of the first segment 21. Compared to using a material with high resistivity for the entire electrode wire 2, this reduces the power loss of the electrode wire 2. Of course, in some other embodiments, other types of materials can be selected according to actual needs. For example, the first segment 21 and the second segment 22 can be made of materials with the same resistivity, but the second segment 22 can be made of a more flexible material. In some other embodiments, the resistivity of the first segment 21 can also be lower than that of the second segment 22. In this case, the material suitable for the first segment 21 is expensive, while the material for the first segment 21 is cheaper, resulting in a lower overall cost for the electrode wire 2.
[0041] In one embodiment, please refer to Figure 1 and Figure 2 The first segment 21 and the second segment 22 are welded together. Specifically, the first segment 21 and the second segment 22 can be welded together using any feasible welding method, such as laser welding, friction welding, etc.
[0042] Furthermore, in one embodiment, please refer to Figure 1 and Figure 2 The outer diameter of the second line segment 22 is less than or equal to the outer diameter of the first line segment 21. This smaller outer diameter of the second line segment 22 facilitates wiring. In some other embodiments, the outer diameter of the second line segment 22 may also be greater than or equal to the outer diameter of the first line segment 21.
[0043] Furthermore, in one embodiment, please refer to Figure 1 and Figure 2 The length of the second segment 22 is greater than the length of the first segment 21. This facilitates the wiring of the second segment 22 and also facilitates its connection to the power supply component. In some other embodiments, the length of the second segment 22 may be equal to or less than the length of the first segment 21.
[0044] Regarding the materials of the first line segment 21 and the second line segment 22, in one embodiment, please refer to... Figure 1 and Figure 2 The first segment 21 is nickel wire. In one embodiment, please refer to... Figure 1 and Figure 2 The second segment 22 is a copper wire. In one embodiment, please refer to... Figure 1and Figure 2 The heating element 1 is a titanium mesh. Using a titanium mesh results in faster heating, and the reliability is better after the nickel wire is welded to the titanium mesh. Copper wire is less expensive, has lower resistivity, and is more flexible, making it easier to install. In some other embodiments, the first segment 21, the second segment 22, and the heating element 1 can be made of any feasible material, depending on actual needs.
[0045] Furthermore, in one embodiment, the anti-corrosion layer 23 is a glass glaze layer, a diamond layer, a platinum layer, or a gold layer. Of course, in some other embodiments, the anti-corrosion layer 23 can also be any other feasible form, such as a ceramic layer or a polymer material layer.
[0046] In one embodiment, please refer to Figure 1 and Figure 2 The anti-corrosion layer 23 is a glass glaze layer. The first line segment 21 is welded to the heating element 1, and then the connection between the first line segment 21 and the heating element 1 is coated with glass glaze and sintered.
[0047] Regarding the location of the anti-corrosion layer 23, in one embodiment, please refer to... Figure 1 and Figure 2 The anti-corrosion layer 23 covers the entire second segment 22. Of course, in some other embodiments, the anti-corrosion layer 23 may only cover the part where the first broken wire is connected to the heating element 1, while the unconnected part is not covered by the anti-corrosion layer 23.
[0048] Furthermore, in one embodiment, the heating component further includes a circuit board, which is soldered to the second wire segment 22. In one embodiment, the second wire segment 22 is made of copper wire, which improves reliability after being soldered to the circuit board. In another embodiment, the copper wire is a copper alloy wire, and a silver layer is also plated on the copper wire to achieve corrosion resistance.
[0049] In one embodiment, please refer to Figure 1 and Figure 2 The heating element 1 is a heating mesh, which can be unfolded or rolled into a cylindrical shape. In one embodiment, please refer to... Figure 1 and Figure 2 Electrode wires 2 are welded to both opposite sides of the heating element 1. One electrode wire 2 is a positive electrode wire 201, and the other electrode wire 2 is a negative electrode wire 202.
[0050] In one embodiment, the heating element is manufactured by first welding the first segment 21 to the heating element 1, then covering the first segment 21 with an anti-corrosion layer 23, and finally connecting the first segment 21 to the second segment 22. In some other embodiments, the first segment 21 and the second segment 22 may be connected first, then the first segment 21 may be welded to the heating element 1, and finally the anti-corrosion layer 23 may be covered on the first segment 21.
[0051] In one embodiment, the aerosol generating device can either heat an aerosol generating rod to generate aerosol or heat an aerosol generating liquid to generate aerosol.
[0052] When using an aerosol generating rod, the aerosol generating rod is inserted into an aerosol generating device. One end of the aerosol generating rod is a suction nozzle, and the other end is an air inlet. The suction nozzle has a suction tip for drawing gas into the aerosol generating rod, and the air inlet is used to supply gas into the aerosol generating rod during suction. In one embodiment, the heating element 1 is a heating tube, and the electrode wire 2 is connected to the heating tube. The aerosol generating rod is inserted into the heating tube and heated.
[0053] When using an aerosol generating liquid, the aerosol generating liquid is pre-added to the aerosol generating device. After the heating element 1 comes into contact with the aerosol generating liquid, the aerosol generating liquid is heated to generate aerosols. In one embodiment, the heating element 1 is a heating mesh.
[0054] In some other embodiments, the heating element 1 can also be any other feasible form, for example, the heating element 1 can be a spiral heating wire.
[0055] In one embodiment of the heating component, the structure of the heating component is the same as that of the heating component described in any of the above embodiments, and will not be repeated.
[0056] 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.
