And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0028] The embodiment of the present application provides a heat - generating component, which can be applied to an atomization device to achieve heating of aerosol products and / or the airflow flowing through the heat - generating component.

[0029] For the heat - generating component of the embodiment of the present application, please refer toFigures 1 to 4 , including a heating element 1, connecting electrodes 2 and leads 3. The heating element 1 has a heating portion 11 and a connecting portion 12 connected to the heating portion 11. The heating portion 11 is mainly used to generate heat to heat the aerosol product and / or the air flow. The heat generated by the connecting portion 12 is less than that generated by the heating portion 11. The connecting portion 12 mainly functions as an electrical connection.

[0030] In one embodiment, please continue to refer to Figures 1 to 4 , the heating element 1 includes a heating sheet. Both the heating portion 11 and the connecting portion 12 are part of the heating sheet, that is, both the heating portion 11 and the connecting portion 12 are in a sheet structure. The contact area between the heating portion 11 and the air flow can be increased by setting a plurality of perforations on the heating portion 11, or by etching grooves on the heating portion 11, thereby improving the heat transfer efficiency between the heating element 1 and the air flow. The connecting portion 12 is used to electrically connect the entire heating element 1 to an external power supply. The connecting portion 12 can be deoxidized to facilitate the electrical connection between the connecting portion 12 and other conductive parts such as the connecting electrode 2. In this way, the contact resistance between the connecting portion 12 and the connecting electrode 2 can be reduced, which helps to reduce the energy consumption of the entire heating component.

[0031] In other embodiments, the shape of the heating element 1 is not limited to a sheet shape, such as a block shape or other special-shaped structures that are convenient to install on the device body of the atomizing device.

[0032] The connecting electrode 2 is riveted to the connecting portion 12 on the heating element 1. In some embodiments, rivet riveting can be used, or non-rivet riveting can also be used, such as non-rivet flanging riveting. In one embodiment, please continue to refer to Figures 1 to 4 , it is provided that the connecting electrode 2 includes an electrode sheet. The thickness direction of the electrode sheet is the same as the thickness direction of the heating sheet. The electrode sheet and the connecting portion 12 are arranged in the thickness direction of the heating sheet, and the electrode sheet is attached to the connecting portion 12, so as to facilitate the riveting of the connecting electrode 2 and the connecting portion 12, especially to facilitate the riveting of the connecting electrode 2 and the connecting portion 12 in a non-rivet manner.

[0033] Furthermore, in one embodiment, it is provided that the area of the electrode sheet is equal to the area of the connecting portion 12 on the heating sheet, which can not only facilitate the riveting of the connecting electrode 2 and the connecting portion 12, but also reduce the contact electrode between the connecting electrode 2 and the connecting portion 12, increase the riveting strength between the heating sheet and the connecting electrode 2, and help to improve the connection reliability of the entire heating component.

[0034] Please refer to Figure 2, in an embodiment where both the connecting portion 12 and the connecting electrode 2 in the heating element 1 are in sheet-like structures, the thickness dimension of the connecting electrode 2 is set to be greater than the thickness dimension of the connecting portion 12 in the heating element 1. This helps to improve the structural strength after riveting the connecting portion 12 and the connecting electrode 2, can reduce the deformation amount of the entire heating assembly, and thus improve the structural reliability of the entire heating assembly. Of course, in some other embodiments, if the thickness dimensions of both the connecting portion 12 and the connecting electrode 2 meet the basic structural strength requirements after riveting the connecting portion 12 and the connecting electrode 2, the thickness dimension of the connecting electrode 2 can also be set to be less than or equal to the thickness dimension of the connecting portion 12.

[0035] In other embodiments, it is also possible to set only one of the connecting portion 12 and the connecting electrode 2 to be in a sheet-like structure, which also facilitates the riveting of the connecting electrode 2 and the connecting portion 12.

[0036] In some embodiments, please refer to Figure 1 and Figure 2 , the heating element 1 is provided to include a strip-shaped heating sheet. The width dimension of the heating sheet is equal everywhere in the length direction of the heating sheet. The length dimension of the heating sheet is 16.5 mm, the width dimension of the heating sheet is 4 mm. The heating portion 11 and the connecting portion 12 are arranged in the length direction of the heating sheet. The connecting portion 12 is located at the end of the heating sheet in the length direction of the heating sheet. The dimension of the connecting portion 12 in the length direction of the heating sheet is 1.2 mm. The heating portion 11 is located in the middle of the heating sheet in the length direction of the heating sheet. The connecting electrode 2 includes an electrode sheet. The shape of the electrode sheet is rectangular. The thickness direction of the electrode sheet is the same as the thickness direction of the heating sheet. The length direction of the electrode sheet is the same as the width direction of the heating sheet. The width direction of the electrode sheet is the same as the length direction of the heating sheet. In the width direction of the heating sheet, the dimension of the electrode sheet is equal to that of the connecting portion 12. In the length direction of the heating sheet, the dimension of the electrode sheet is equal to that of the connecting portion 12. That is, the length dimension of the electrode sheet is 4 mm, and the width dimension of the electrode sheet is 1.2 mm. This can prevent the edge of the electrode sheet from exceeding the edge of the heating sheet and facilitate the riveting of the electrode sheet and the connecting portion 12.

[0037] In some embodiments, please refer to Figures 1 to 4 , the extending direction of the lead 3 is the same as the width direction of the heating sheet. The lead 3 is located on the side of the electrode sheet facing away from the heating sheet in the arrangement direction of the heating sheet and the electrode sheet. The cross-section of the lead 3 is circular. The outer peripheral surface of the lead 3 is attached to the side of the electrode sheet facing away from the heating sheet to facilitate the welding of the lead 3 and the electrode sheet. The lead 3 can be provided with a welding portion 30 connected to the connecting electrode 2, that is, to the electrode sheet. The lead 3 is welded to the electrode sheet through its welding portion 30. It is set that in the width direction of the heating sheet, in the width direction of the heating sheet, the dimension of the welding portion 30 is equal to that of the electrode sheet. This helps to increase the welding area between the lead 3 and the electrode sheet, helps to improve the connection strength between the lead 3 and the connecting electrode 2, and thus reduces the probability of the lead 3 falling off.

[0038] Certainly, in other embodiments, an angle less than 90° may be provided between the extending direction of the lead 3 and the width direction of the heating sheet. In this way, the length of the welding portion 30 on the lead 3 for welding with the electrode sheet can be increased, the welding area between the lead 3 and the electrode sheet can be further increased, thereby further improving the connection strength between the lead 3 and the connecting electrode 2 and reducing the probability of the lead 3 falling off.

[0039] Or in other embodiments, in the width direction of the heating sheet, the size of the welding portion 30 on the lead 3 may be slightly smaller than the size of the electrode sheet, as long as it can ensure that the lead 3 is welded to the electrode sheet through the welding portion 30.

[0040] In one embodiment, a laser welding method can be used to connect the lead 3 and the connecting electrode 2 to facilitate the automated assembly of the heating component and help ensure the structural consistency of the heating component; in another embodiment, a resistance welding method can also be used to connect the lead 3 and the connecting electrode 2.

[0041] Generally, the heating element 1 in the heating component is made of materials such as titanium, platinum, nickel, or iron-nickel alloy, and the lead 3 is usually made of silver wire or nickel wire. If the heating element 1 made of titanium or platinum material is directly welded to the lead 3, the lead 3 is likely to fall off. In this application, a connecting electrode 2 is provided in the heating component, and the connecting electrode 2 is connected to the connecting portion 12 on the heating element 1 by riveting, and then the lead 3 is welded to the connecting electrode 2. In this way, it is convenient to select connecting electrodes 2 made of different materials, such as nickel or silver materials, so that the welding strength between the connecting electrode 2 and the lead 3 is greater than the direct welding strength between the heating element 1 and the lead 3, so as to improve the connection strength of the lead 3 in the entire heating component and thus reduce the probability of the lead 3 falling off.

[0042] In some embodiments, the heating element 1 is made of titanium or platinum material, and the material of the connecting electrode 2 is the same as that of the lead 3. For example, both the connecting electrode 2 and the lead 3 can be made of silver material, or they can also be made of nickel material. After the connecting electrode 2 is riveted to the heating element 1, the connecting electrode 2 is welded to the lead 3. The connecting electrode 2 and the lead 3 are made of the same material, the melting points of the connecting electrode 2 and the lead 3 are the same, and the strength after welding between the connecting electrode 2 and the lead 3 is greater than the direct welding strength between the lead 3 and the heating element 1. In this way, it helps to improve the connection strength of the lead 3 in the entire heating component and thus reduce the probability of the lead 3 falling off. In other embodiments where the connecting electrode 2 and the lead 3 are made of the same material, the same material can also be other materials besides silver and nickel, as long as the material meets the requirements of high temperature resistance, high conductivity, and high welding strength.

[0043] In some other embodiments, the connecting electrode 2 can also be made of FeCrAl material, and the lead wire 3 can be made of nickel wire. Although the materials of the connecting electrode 2 and the lead wire 3 are different, since the melting points of the FeCrAl material and the nickel material are similar, the connection strength after welding the connecting electrode 2 and the lead wire 3 can also be ensured to be greater than the strength of directly welding the lead wire 3 to the heating element 1, and the probability of the lead wire 3 falling off can also be reduced.

[0044] In some other embodiments, the lead wire 3 can also be provided with a welding portion 30 for welding with the connecting electrode 2, and the connecting electrode 2 can be provided with a welding connection portion 20 for connecting with the lead wire 3, and only the welding portion 30 and the welding connection portion 20 are made of the same material. In one embodiment, the lead wire 3 is a silver-plated copper wire, the connecting electrode 2 is an alloy sheet with a silver coating on the outside, the welding portion 30 in the lead wire 3 is a silver-plated layer attached to the copper wire, the welding connection portion 20 in the connecting electrode 2 is a silver-plated layer attached to the alloy, and the welding portion 30 and the welding connection portion 20 are both made of the same material. In this way, the connection strength of the lead wire 3 in the entire heating component can also be improved after welding the lead wire 3 and the connecting electrode 2, thereby reducing the probability of the lead wire 3 falling off; or in some other embodiments, the coatings on the lead wire 3 and the connecting electrode 2 can both be nickel layers, and the above effects can also be achieved.

[0045] In some embodiments, the lead wire 3 in the heating component includes a first lead wire 31 and a second lead wire 32 with opposite polarities. The first lead wire 31 can be a positive lead wire, and the second lead wire 32 can be a negative lead wire. The first lead wire 31 and the second lead wire 32 can both have the same structure as the lead wire 3 described in any of the above embodiments; correspondingly, a first connection portion 121 and a second connection portion 122 corresponding to the first lead wire 31 and the second lead wire 32 are respectively provided on the heating element 1. The two connection portions 12 can be arranged on both sides of the heating portion 11 in the length direction of the heating sheet, and the two connection portions 12 respectively have the same structure as the connection portion 12 described in any of the above embodiments; correspondingly, the connecting electrode 2 is provided to include a first connecting electrode 21 and a second connecting electrode 22 with opposite polarities. The structures of the first connecting electrode 21 and the second connecting electrode 22 are the same as the structure of the connecting electrode 2 described in any of the above embodiments; the first connecting electrode 21 is riveted to the first connection portion 121 on the heating element 1, the second connecting electrode 22 is riveted to the second connection portion 122 on the heating element 1, the first lead wire 31 is located on the side of the first connecting electrode 21 facing away from the heating element 1 in the arrangement direction of the first connecting electrode 21 and the heating element 1, and the first lead wire 31 is welded to the first connecting electrode 21. The second lead wire 32 is located on the side of the second connecting electrode 22 facing away from the heating element 1 in the arrangement direction of the second connecting electrode 22 and the heating element 1, and the second lead wire 32 is welded to the second connecting electrode 22. In this way, the connection strength of each lead wire 3 in the heating component can be ensured, thereby reducing the probability of the lead wire 3 falling off.

[0046] In other embodiments, if only one of the leads 3 in the heating component is prone to detachment, only one of the leads 3 may be provided to be connected to the heating element 1 by the corresponding connection electrode 2 in the above connection manner.

[0047] An embodiment of the present application further provides an atomization device, which includes a device main body and the heating component in any of the above embodiments. The device main body has an air flow channel, and the heating component is installed on the device main body.
