For specific details, please refer to the following embodiments.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 In the first embodiment of the present application, a heating element 10 is provided, which is applied to the atomization assembly 20 in an aerosol generating device to heat and atomize a liquid aerosol generating matrix. The heating element 10 includes a first pin 11, at least two second pins 12, and at least two heating bodies 13. The first pin 11 and all the second pins 12 are arranged side by side and spaced apart along the first direction. The heating body 13 includes a heating part 131, a first connection part 132, and a second connection part 133 which are integrally arranged. The first connection part 132 and the second connection part 133 are respectively located at both ends of the heating part 131. The first connection part 132 is welded and fixed to the first pin 11, and the second connection part 133 is welded and fixed to the second pin 12. All the heating parts 131 are arranged side by side and spaced apart.

[0039] It can be understood that the heating element 10 provided in the present application is installed in the atomization component 20 of the aerosol generating device and is used to heat the liquid aerosol generating matrix to atomize and generate aerosol for users to use. The heating element 10 includes a first pin 11, at least two second pins 12, and at least two heating bodies 13. The first pin 11 and the second pins 12 are used to externally connect to the control circuit board or battery cell in the aerosol generating device to ensure normal power supply to the heating element 10. The heating body 13 includes a heating part 131, a first connection part 132, and a second connection part 133 made integrally. The heating part 131 is used to directly heat the liquid aerosol generating matrix to atomize and generate aerosol. The first connection part 132 and the second connection part 133 are respectively used to weld and fix the first pin 11 and the second pins 12 to realize normal power supply from the external battery cell to the heating part 131. The first pin 11 and all the second pins 12 are arranged side by side and spaced apart along the first direction. One end of all the heating parts 131 is electrically connected to the same first pin 11 through the first connection part 132, and the other end is electrically connected to a second pin 12 through the second connection part 133 respectively. So that multiple heating parts 131 can form multiple heating circuits after being externally powered by the first pin 11 and the second pins 12, which is convenient for users to adjust the number of access circuits to adjust the atomization power of the heating element 10, effectively increasing the selectivity and diversity of the heating element 10 in atomization power adjustment, and can realize the adjustment of various fog output amounts, which is beneficial to enrich the user's taste. For example: when the first pin 11 is connected to negative power supply or positive power supply, and the second pins 12 are connected to positive power supply or negative power supply, multiple heating parts 131 can form multiple parallel heating circuits after being externally powered by the first pin 11 and the second pins 12. At the same time, multiple heating parts 131 are used. During use, the multiple heating parts 131 are attached to the inner wall of the atomization holes 221 of the liquid guiding part 22, which can improve the space utilization rate and increase the total heating area, which is beneficial to improving the atomization efficiency. The structure and size of the heating part 131 determine the heating area of the heating part 131. When multiple heating parts 131 are externally powered through the first pin 11 at both ends and multiple second pins 12, due to the spaced distribution of the second pins 12, there must be differences in size between multiple heating parts 131. The first pin 11 is welded and fixed through the first connection part 132 at both ends of the heating part 131, and the second pin 12 is welded and fixed through the second connection part 133 to realize external power supply. The size of the heating part 131 can be ensured to meet the requirements by adjusting the sizes of the first connection part 132 and the second connection part 133, that is, ensuring that the heating area meets the design requirements. For example: when the structures and sizes of multiple heating parts 131 are designed to be the same, the sizes of the first connection part 132 and the second connection part 133 connected to the conductive part are adjusted to ensure that multiple second pins 12 are spaced apart, ensuring that multiple heating circuits can be independently controlled.

[0040] An example of the operation of the heating element 10 is as follows:

[0041] The heating element 10 includes a first pin 11, three second pins 12, and three heating bodies 13. One ends of the three heating bodies 13 are commonly connected to the same first pin 11, and the other ends are respectively connected to a second pin 12. After external power supply is connected to the first pin 11 and the second pins 12, three independent heating circuits A, B, and C are formed; after the external power supply is turned on, the three heating circuits can be set to work in a mode where a single heating circuit works in turn (for example: A, B, C work in turn), or two of them work in turn (for example: AB, AC work in turn), or the three meshes work simultaneously (for example: ABC work simultaneously), and at this time, a relatively large atomization power can be provided. Therefore, three different powers can be generated.

[0042] The three heating circuits can adopt a control method for balancing losses. Before each start of work, it is judged according to the accumulated heat generation amount of the heating parts 131 in the three heating circuits, and the heating part 131 with the least heat generation amount is selected to work. The heat generation amount of the mesh is obtained by integrating the high-level state of the CHECK pin in the circuit. Specifically, in the single-shot working mode, when starting to work each time, the main control MCU judges the accumulated heat generation amounts of the three heating parts 131 and selects the heating part 131 with the least accumulated heat generation amount to work; in the dual-shot working mode, when starting to work each time, the main control MCU judges the accumulated heat generation amounts of the three heating parts 131 and selects the two heating parts 131 with the least accumulated heat generation amounts to work; in the triple-shot working mode, the three heating parts 131 work simultaneously.

[0043] Please continue to refer to Figure 2 and Figure 3 , in some embodiments, the heating part 131 is in a mesh shape.

[0044] It can be understood that the heating part 131 is in a mesh shape and is formed by continuously bending and connecting at least two heating wires, so that the heating part 131 uniformly heats the liquid aerosol generating matrix, which is beneficial to improving the uniformity of aerosol fogging and enhancing the user experience.

The first connecting part 132 and the second connecting part 133 are respectively located at two ends of the heating part 131 perpendicular to the first direction, that is, one end of all the heating parts 131 is commonly connected to the same first connecting part 132, and the other end is respectively connected to a second connecting part 133. Then, one end of the first connecting part 132 is welded and fixed to the first pin 11, and the second pin 12 is welded and fixed through the second connecting part 133 for external power supply to form a plurality of independent heating circuits, facilitating the user to adjust the number of connected circuits to adjust the atomization power of the heating element 10, effectively increasing the selectivity and diversity of the heating element 10 in atomization power adjustment, enabling adjustment of various fog output amounts, and being beneficial to enriching the user's taste.

When a plurality of heating bodies 13 are integrally manufactured, the plate can be first stamped and etched and then bent into a tube, and finally welded and fixed to the first pin 11 and the second pin 12 to form the heating element 10.
