[0043] Optionally, the heating structure 20 can be a one-piece structure, that is, the first connector 21, the second connector 22, and the multiple heating elements 23 are manufactured as a single piece using a molding process. This allows for heat transfer between the multiple heating elements 23, reducing the temperature difference between them and improving the temperature uniformity of the heating structure 20.

All multiple heating elements 23 can atomize the oil, which increases the heating area and makes the heating uniform. The heating elements 23 do not need to work at excessively high power to have a large atomization volume. The atomizing component 100 has a long service life and a good user experience.

All of the above methods are acceptable and there is no specific limitation.

[0047] By setting the heating element 23 to be in close contact with the outer peripheral surface 13, and / or by embedding at least a portion of the heating element 23 into the outer peripheral surface 13, leaving no gap between the heating element 23 and the outer peripheral surface 13, interference between the portion of the heating element 23 protruding from the outer peripheral surface 13 and other components of the electronic atomizer is avoided. Furthermore, the heating element 23 can atomize the liquid to be atomized in the atomizing core 10 in a timely manner, preventing un-atomized liquid from flowing out between the atomizing core 10 and the heating element 23, thereby improving heating efficiency.

[0048] In one embodiment, please refer to Figure 1 and Figure 2 In the orthographic projection of the first direction Z, the outline of the atomizing core 10 is rectangular, and the outer peripheral surface 13 includes a plurality of side surfaces 131 connected end to end in sequence. Each adjacent and / or opposite side surface 131 is connected to at least one heating element 23.

The first side and the third side are spaced apart in the second direction X, and the second side and the fourth side are spaced apart in the third direction Y. The first direction Z, the second direction X and the third direction Y are perpendicular to each other.

[0050] Optionally, the dimensions of the first and third sides in the third direction Y are the same as the dimensions of the second and fourth sides in the second direction X, that is, in the orthographic projection of the first direction Z, the outline shape of the atomizing core 10 is square.

[0051] Optionally, a heating element 23 is connected to the first side and the second side; or, a heating element 23 is connected to the first side and the third side; or, a heating element 23 is connected to the first side, the second side and the third side; or, a heating element 23 is connected to each side 131.

[0052] In one embodiment, such as Figure 2 As shown, each side 131 is connected to a heating element 23. Alternatively, each side 131 is connected to two heating elements 23, meaning the heating structure 20 includes eight heating elements 23, with two heating elements 23 connected to the same side 131 spaced apart along a second direction X or a third direction Y. Alternatively, the number and arrangement of the heating elements 23 can be implemented in any feasible manner, without any specific limitation.

[0053] In another embodiment, please refer to Figure 3 In the orthographic projection in the first direction Z, the outline of the atomizing core 10 is circular. Optionally, a plurality of the heating elements 23 are arranged at circumferential intervals along the outer peripheral surface 13.

[0054] In specific embodiments, such as Figure 3 As shown, in the orthographic projection of the first direction Z, the outline of the atomizing core 10 is circular, and there are four heating elements 23, which are arranged circumferentially along the outer peripheral surface 13.

[0055] Alternatively, in the orthographic projection of the first direction Z, the outline shape of the atomizing core 10 can also be a triangle, trapezoid, parallelogram, ellipse, irregular shape, etc., without any specific restrictions.

[0056] By setting the outline shape of the atomizing core 10 to be rectangular or circular, the rectangular atomizing core 10 has heating elements 23 on at least two sides 131, and the circular atomizing core 10 has multiple heating elements 23 spaced apart on its outer peripheral surface 13. This can increase the heating area and make the heating uniform. The heating elements 23 do not need to work with excessive power to have a large atomization volume. The atomizing component 100 has a long service life and a good user experience.

[0057] In one embodiment, please refer to Figure 4The heating element 23 includes a plurality of heating units 231 connected in sequence in the first direction Z, and the heating unit 231 is a ring structure connected end to end.

[0058] Optionally, the number of heating units 231 in the heating element 23 can be 2 to 8, specifically 2, 3, 4, 5, 8, etc., without limitation. Optionally, the number of heating units 231 in multiple heating elements 23 can be the same or different, without limitation. Optionally, the multiple heating units 231 of the heating element 23 can be an integral structure, or they can be detachably connected by means of snap-fit, screw-fit, riveting, etc., without limitation. Optionally, multiple heating units 231 can also be arranged in the circumferential direction on the outer peripheral surface 13 of the heating element 23 to improve the heat generation of the heating element 23, without limitation.

[0059] Optionally, the heating unit 231 is surrounded by structural holes. The outer contour shape of each heating unit 231 can be spindle-shaped, rectangular, circular, or elliptical, etc., without limitation. The inner contour shape of each heating unit 231 can also be spindle-shaped, rectangular, circular, or elliptical, etc., without limitation. Optionally, the outer contour shape and inner contour shape of each heating unit 231 are set correspondingly.

[0060] By setting the heating element 23 to include multiple heating units 231 connected in sequence in the first direction Z, each heating unit 231 can atomize the oil. The resistance value of the heating unit 231 is easy to control, which increases the heating area and makes the heating uniform, thereby increasing the atomization amount.

[0061] In one embodiment, such as Figure 2 and Figure 4 As shown, the first connector 21 includes a plurality of first connecting parts 211 and a plurality of first transition parts 212. The plurality of first connecting parts 211 are connected to a plurality of heating elements 23 in a one-to-one correspondence. Two adjacent first connecting parts 211 are connected by a first transition part 212. The surface of the first connecting part 211 facing away from the outer peripheral surface 13 is flush and coplanar with the surface of the heating element 23 facing away from the outer peripheral surface 13.

[0062] Optionally, the first connector 21 can be an integral structure or a separate structure. The first connecting part 211 and the first transition part 212 are connected and fixed by welding, bonding, snap-fitting, screwing, etc., and there is no specific limitation. Optionally, the first connector 21 is strip-shaped and extends circumferentially along the outer peripheral surface 13. There is a gap between the first end and the last end of the first connector 21 to avoid short circuit due to the first and last ends being connected.

[0063] Optionally, the first connecting portion 211 is connected to the outermost heating unit 231 of the heating element 23 in the first direction Z. The dimension of the circumferential extension of each first connecting portion 211 along the outer peripheral surface 13 is approximately the same as the dimension of the circumferential extension of the corresponding heating element 23 along the outer peripheral surface 13.

[0064] For example, if the atomizing core 10 has a rectangular outline, then the length of the first connecting part 211 and the heating unit 231 are approximately the same, and the surface of the first connecting part 211 facing away from the outer peripheral surface 13 is flush with the surface of the heating element 23 facing away from the outer peripheral surface 13 (i.e., located in the same plane); if the atomizing core 10 has a circular outline, then the curvature of the first connecting part 211 and the heating unit 231 is the same as the curvature of the outer peripheral surface 13, the arc length of the first connecting part 211 and the heating unit 231 is the same, and the surface of the first connecting part 211 facing away from the outer peripheral surface 13 and the surface of the heating element 23 facing away from the outer peripheral surface 13 are located in the same arc surface.

[0065] Optionally, in the orthographic projection of the first direction Z, the shape of the first transition portion 212 is similar to the shape of the outer peripheral surface 13 located between two adjacent heating elements 23. For example, if the outline shape of the atomizing core 10 is rectangular, then the first transition portion 212 is "L"-shaped; or, if the outline shape of the atomizing core 10 is circular, then the first transition portion 212 is arc-shaped. The arrangement of the first transition portion 212 and the outer peripheral surface 13 is similar to that of the heating element 23, and can be referred to accordingly without further explanation.

[0066] Similarly, the second connector 22 includes multiple second connecting parts and multiple second transition parts. The specific structure of the second connector 22 can be referred to the first connector 21 mentioned above, and will not be repeated here.

[0067] Optional, such as Figure 4 and Figure 5 As shown, the ends of the first connector 21 and / or the second connector 22 are also connected to a protrusion 25, which is used to electrically connect with the circuit components of the electronic atomizer to control the heating structure 20.

[0068] The first connector 21 includes multiple first connecting parts 211 and first transition parts 212. The first connecting parts 211 are connected to the heating element 23. The surface of the first connecting part 211 facing away from the outer peripheral surface 13 is flush and coplanar with the surface of the heating element 23 facing away from the outer peripheral surface 13. The first transition part 212 is in close contact with or embedded in the outer peripheral surface 13. The first connector 21 is in close contact with the outer peripheral surface 13, and the surface of the heating structure 20 facing away from the outer peripheral surface 13 is relatively flat, avoiding interference with other parts of the electronic atomizer and ensuring safe use.

[0069] In one embodiment, such as Figure 4 and Figure 5 As shown, the heating structure 20 also includes a plurality of fasteners 24. At least one heating element 23 is connected to a fastener 24 on the surface facing the outer peripheral surface 13. The fastener 24 is embedded in the outer peripheral surface 13.

[0070] Optionally, multiple fixing members 24 are housed inside the aforementioned atomizing core 10 and connected and fixed to the atomizing core 10. Optionally, the fixing members 24 are housed inside the side peripheral wall 15. Optionally, the fixing members 24 and the heating element 23 can be an integral structure, or they can be detachably connected to the heating element 23 by means of snap-fit, screw-fit, or riveting, without limitation.

[0071] Optionally, at least one fixing member 24 is connected to the surface of at least one heating unit 231 of the heating element 23 facing the outer peripheral surface 13. Optionally, fixing members 24 are connected to both ends of the heating unit 231 along the circumferential direction of the outer peripheral surface 13. Optionally, the heating element 23 includes a plurality of fixing members 24 spaced apart in the first direction Z, and at least two heating units 231 are respectively connected to fixing members 24. Optionally, fixing members 24 are connected to both ends of each heating unit 231 along the circumferential direction of the outer peripheral surface 13. Optionally, each heating element 23 is similar to the aforementioned structure, and can be referred to without further description. The arrangement of fixing members 24 and heating units 231 in each heating element 23 can be the same or different, without limitation.

[0072] Optionally, the first connector 21 is connected to a fastener 24 on the surface of the outer peripheral surface 13, and / or the second connector 22 is connected to a fastener 24 on the surface of the outer peripheral surface 13.

[0073] By setting multiple fasteners 24, which are connected to the surface of the heating element 23 facing the outer peripheral surface 13, the connection stability between the heating structure 20 and the atomizing core 10 is improved, preventing the heating structure 20 from detaching from the atomizing core 10.

[0074] In one implementation, such as Figure 4 and Figure 5 As shown, each fastener 24 includes an extension 241 and a fixing part 242. One end of the extension 241 is connected to the fixing part 242, and the end of the extension 241 away from the fixing part 242 is connected to the heating element 23.

[0075] Optionally, the extension 241 and the fixing part 242 can be an integral structure, or they can be detachably connected by means of snap-fit, screw-fit, or riveting, without limitation. Optionally, the fixing part 242 is suitable for connection and fixing with the atomizing core 10, so that the heating structure 20 and the atomizing core 10 are relatively fixed. Optionally, the fixing part 242 can be a hook or a boss, or it can have a notch, without limitation.

[0076] By setting each fixing member 24 to include an extension 241 and a fixing part 242, with the fixing part 242 connected to one end of the extension 241 and the end of the extension 241 away from the fixing part 242 connected to the heating element 23, the fixing member 24 can extend into the atomizing core 10 and be fixed to the atomizing core 10. The structure is simple and easy to process and shape.

[0077] Please refer to Figure 4 and Figure 5 The fixing part 242 protrudes from the extension part 241 in the first direction Z.

[0078] Optionally, the fixing part 242 may protrude from one surface of the extension part 241 in the first direction Z, or it may protrude from two opposite surfaces of the extension part 241 in the first direction Z, without limitation. By setting the fixing part 242 to protrude from the extension part 241 in the first direction Z, the fixing part 242 can be snapped and fixed with the atomizing core 10, further improving the connection stability between the heating structure 20 and the atomizing core 10.

[0079] In one embodiment, such as Figure 2 As shown, in the first direction Z, the atomizing core 10 has a first dimension A, and the heating structure 20 has a second dimension B, satisfying: 1 / 3 ≤ B / A ≤ 3 / 4. By setting the first dimension A of the atomizing core 10 and the second dimension B of the heating structure 20 to satisfy the above relationship, the heating structure 20 can provide a larger heating area, resulting in more uniform heating. It can provide a larger atomization volume without excessively high heating power, reducing costs and extending the service life of the heating structure 20. When B / A is too large, the area of ​​the heating structure 20 is too large, which may cause partial dry burning of the heating element 23, resulting in scorching and posing a certain safety hazard. When B / A is too small, the area of ​​the heating structure 20 is insufficient, resulting in insufficient atomization volume, which may affect the user experience. Optionally, the specific value of B / A can be 1 / 3, 5 / 12, 1 / 2, 7 / 12, 2 / 3, 3 / 4, etc.

[0080] Optionally, in the first direction Z, the heating structure 20 is closer to the bottom surface 11 than the top surface 12. With this configuration, the heating structure 20 can better atomize the liquid to be atomized in the liquid inlet chamber 14, reduce the residue of the liquid to be atomized in the liquid inlet chamber 14, and avoid waste.

[0081] In one embodiment, in the orthographic projection in the first direction Z, the area enclosed by the outer peripheral surface 13 is S1, and the area of ​​the liquid inlet cavity 14 is S2, satisfying: 1 / 3 ≤ S2 / S1 ≤ 2 / 3. Because the area S1 enclosed by the outer peripheral surface 13 and the area S2 of the liquid inlet cavity 14 satisfy the above relationship, the atomizing core 10 has a reliable structure, and the heating structure 20 can promptly atomize the liquid to be atomized in the liquid inlet cavity 14 of the atomizing core 10, resulting in sufficient atomization and high atomization efficiency. When S2 / S1 is too large, the volume occupied by the liquid inlet cavity 14 is too large. On the one hand, this may lead to a thinner sidewall 15 of the atomizing core 10, resulting in insufficient connection stability between the heating structure 20 and the atomizing core 10. On the other hand, the liquid to be atomized cannot be fully dispersed into small droplets by the atomizing core 10, which may lead to insufficient atomization. When S2 / S1 is too small, the volume of the liquid inlet cavity 14 is small, which may lead to insufficient atomization, affecting the user experience, and also causing more liquid to remain in the atomizing core 10, resulting in waste. Optionally, the specific values ​​of S2 / S1 can be 1 / 3, 5 / 12, 1 / 2, 7 / 12, 2 / 3, etc.
