[0040] Please refer to Figure 2 and Figure 3 This utility model also provides a heating structure 100, which includes a heating element 10. The heating element 10 includes a plurality of connecting portions 11, a plurality of first heating portions 12, and a plurality of second heating portions 13. The plurality of connecting portions 11 are arranged sequentially at intervals in the first direction X. The plurality of first heating portions 12 are connected to the plurality of connecting portions 11 in a one-to-one correspondence. Each first heating portion 12 includes a first segment 121 and a second segment 122. The first segment 121 and the second segment 122 are both connected to the same end of the connecting portion 11 in the second direction Z. The first segment 121 of one of two adjacent first heating portions 12 is connected to the second segment 122 of the other. The widths of the first segment 121, the second segment 122, and the connecting portion 11 are equal. The plurality of second heating portions 13 are connected to the plurality of connecting portions 11 in a one-to-one correspondence and are symmetrical to the axis extending along the first direction X relative to the plurality of first heating portions 12. The first direction X and the second direction Z intersect.

[0041] Specifically, in two adjacent first heating elements 12, in the first direction X, the end of the second segment 122 of the preceding first heating element 12 away from the connecting portion 11 is connected to the end of the first segment 121 of the following first heating element 12 away from the connecting portion 11.

[0042] In one implementation, please refer to Figure 3Two adjacent first heating elements 12, two corresponding second heating elements 13, and two corresponding connecting elements 11 enclose each other to form a first annular structure 18. In the orthographic projection on the third direction Y, the first annular structure 18 is rhomboid or spindle-shaped.

[0043] In one implementation, please refer to Figure 3 The first segment 121 and the second segment 122 are symmetrical about an axis extending along the second direction Z. Specifically, the first segment 121 and the second segment 122 are symmetrical about a second axis L2 extending along the second direction Z. Optionally, the first segment 121, the second segment 122, and the connecting portion 11 all extend in a straight line. The first segment 121 and the second segment 122 are located on opposite sides of the connecting portion 11 in the first direction X, and both the first segment 121 and the second segment 122 are inclined relative to the length direction of the connecting portion 11.

[0044] In one implementation, please refer to Figure 3 The first heating element 12 has a maximum dimension of W in the first direction X and a maximum dimension of H1 in the second direction Z. The connecting element 11 has a maximum dimension of H2 in the second direction Z, satisfying: 3≤H1 / W≤5 and 3≤H1 / H2≤5. Optionally, H1 / W can be 3, 3.5, 4, 4.5, and 5, etc., without limitation. Optionally, 3≤H1 / H2≤5 can be 3, 3.5, 4, 4.5, and 5, etc., without limitation. The maximum dimension of the first heating element 12 in the first direction X is W, and the maximum dimension in the second direction Z is H1. The maximum dimension of the connecting part 11 in the second direction Z is H2. By setting 3≤H1 / W≤5, the multiple first heating elements 12 have a large heating area, and the heating of the multiple first heating elements 12 is more uniform. At the same time, setting 3≤H1 / H2≤5, the distance between the multiple first heating elements 12 and the multiple second heating elements 13 in the second direction Z is moderate, so that the heating element 10 has a large heating area while ensuring the uniformity of heating of the heating element 10.

[0045] In one implementation, please refer to Figure 3The angle between the first segment 121 and the second segment 122 is A, and the angle between the first segment 121 and the connecting part 11 is B, satisfying: 5 ≤ A / B ≤ 7.

The angle A between the first segment 121 and the second segment 122 can be 20°, 25°, 30°, 35°, 40°, or 45°, etc., without limitation.

For example, the angle B between the first segment 121 and the connecting part 11 is 170°.

[0046] By setting the angle between the first segment 121 and the second segment 122 to A, and the angle between the first segment 121 and the connecting part 11 to B, satisfying 5≤A / B≤7, the angle between the first segment 121, the second segment 122 and the connecting part 11 is moderate, so that the heating element 10 has a large heating area while ensuring the uniformity of heating of the heating element 10.

[0047] In one implementation, please refer to Figure 2 and Figure 3 The heating element 10 also includes a third heating part 14 and a fourth heating part 15.

The sixth heating part 17 is symmetrical to the fourth heating part 15 along an axis extending in the first direction X. The fifth heating part 16 is connected to the first segment 121 of the first second heating part 13 in the first direction X. The sixth heating part 17 is connected to the third segment of the last second heating part 13 in the first direction X.

[0049] Optionally, the third heating element 14, the fifth heating element 16, the first first heating element 12 and the first second heating element 13 in the first direction X enclose to form a second annular structure 19, and the fourth heating element 15, the sixth heating element 17, the last first heating element 12 and the last second heating element 13 in the first direction X enclose to form a third annular structure 120. Optionally, in the orthographic projection in the third direction Y, the second annular structure 19 and the third annular structure 120 are rhomboid or spindle-shaped.

[0050] By providing a third heating element 14 and a fourth heating element 15, which are spaced apart from each other in the first direction X, the first segment 121 of the first heating element 12 is connected to the third heating element 14, and the second segment 122 of the last heating element 12 is connected to the fourth heating element 15. The widths of the third heating element 14, the fourth heating element 15 and the first segment 121 are equal, thereby further increasing the heating area of ​​the heating element 10.

[0051] In one implementation, please refer to Figure 3 The third heating element 14 and the fourth heating element 15 are symmetrical about an axis extending along the second direction Z. Specifically, the third heating element 14 and the fourth heating element 15 are symmetrical about a third axis L3, which extends along the second direction Z and passes through the midpoint of the heating element 10 in the first direction X. Optionally, the fifth heating element 16 and the sixth heating element 17 are symmetrical about the third axis L3. Optionally, the second annular structure 19 and the third annular structure 120 are symmetrical about the third axis L3.

[0052] By setting the third heating part 14 and the fourth heating part 15 symmetrically relative to the axis extending along the second direction Z, the heating area of ​​the heating element 10 is increased without reducing the heating uniformity of the heating element 10.

[0053] In one implementation, please refer to Figure 3 The angle between the first segment 121 and the second segment 122 is A, the angle between the third heating part 14 and the first segment 121 is C, and the angle between the fourth heating part 15 and the second segment 122 is D, satisfying: A=C, and / or, A=D.

[0054] Specifically, the first segment 121, the second segment 122, the third heating element 14, and the fourth heating element 15 all extend along a straight line. The third heating element 14 is arranged parallel to the second segment 122, and the fourth heating element 15 is arranged parallel to the first segment 121. Optionally, since the fifth heating element 16 and the third heating element 14 are symmetrically arranged, and the sixth heating element 17 and the fourth heating element 15 are symmetrically arranged, the fifth heating element 16 is arranged parallel to the second segment 122 of the second heating unit, and the sixth heating element 17 is arranged parallel to the first segment 121 of the second heating unit.

[0055] By setting the angle between the first segment 121 and the second segment 122 to A, the angle between the third heating element 14 and the first segment 121 to C, and the angle between the fourth heating element 15 and the second segment 122 to D, satisfying: A=C, and / or, A=D, the heating uniformity of the heating element 10 is further improved.

[0057] Optionally, the two heating elements 10 can be an integral structure, allowing temperature transfer between them, reducing the temperature difference between them, and improving the temperature uniformity of the heating structure 100. Alternatively, the two heating elements 10 can be separate structures to reduce the manufacturing difficulty of the heating elements 10.

[0058] Optionally, both the first connector 20 and the second connector 30 are connected to the aforementioned circuit assembly, with one configured as the positive electrode and the other as the negative electrode. Optionally, both the first connector 20 and the second connector 30 are connected and fixed to the aforementioned atomizing core 200. Optionally, the first connector 20, the second connector 30, and the two heating elements 10 can be an integral structure, or they can be detachably connected by means of snap-fit, screw-fit, or riveting, without limitation.

[0059] By setting two heating elements 10, which are relatively spaced apart in the third direction Y, and intersecting with both the first direction X and the second direction Z, the heating area of ​​the heating structure 100 is made larger, and the heating uniformity of the atomizing component 1000 is improved. By setting a first connector 20 and a second connector 30, which are relatively spaced apart in the first direction X and both connected to the two heating elements 10, the two heating elements 10 can be connected in parallel through the first connector 20 and the second connector 30, so that the voltage through the two heating elements 10 is the same, further improving the heating uniformity.

[0060] In one implementation, please refer to Figure 1 and Figure 2 The heating structure 100 also includes a plurality of fixing members 40, which are connected to at least one of the heating element 10, the first connecting member 20, and the second connecting member 30. All fixing members 40 are connected and fixed to the atomizing core 200 to improve the connection strength between the heating structure 100 and the atomizing core 200. Optionally, the fixing member 40 may be a hook structure connected to the first connecting member 20 and the second connecting member 30, and / or, the fixing member 40 may be a block structure connected to the heating element 10 to increase the connection area between the heating structure 100 and the atomizing core 200.

[0061] By setting the heating structure 100 to include a heating element 10, the heating element 10 includes multiple connecting parts 11, multiple first heating parts 12 and multiple second heating parts 13. The multiple connecting parts 11 are arranged sequentially at intervals in the first direction X. The multiple first heating parts 12 are connected to the multiple connecting parts 11 in a one-to-one correspondence. Each first heating part 12 includes a first segment 121 and a second segment 122. The first segment 121 and the second segment 122 are both connected to the same end of the connecting part 11 in the second direction Z. The first segment 121 of one of two adjacent first heating parts 12 is connected to the second segment 122 of the other. The width of the first segment 121, the second segment 122 and the connecting part 11 are equal. The multiple second heating parts 13 are connected to the multiple connecting parts 11 in a one-to-one correspondence and are symmetrical with the multiple first heating parts 12 along the axis extending in the first direction X. The first direction X and the second direction Z intersect, so that the heat generation difference between the parts of the heating element 10 is small, and the heat generation uniformity of the heating element 10 is improved.
