[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0033] See also Figure 1 and Figure 2 , Figure 1 What is shown is a perspective view of a microporous ceramic atomization core used in the related technology; Figure 2It is a schematic diagram of the unfolded state of the heating element 2, wherein the microporous ceramic atomization core mainly includes a microporous ceramic body 1, a heating element 2 and a lead 3. The middle part of the microporous ceramic body 1 has a through hole 11 that runs through it, and the whole is a cylindrical structure. The middle part of the heating element 2 is a heating part formed by multiple repeated heating units, and the upper and lower ends of the heating part are respectively provided with protruding structures. The lead 3 is electrically connected to the heating element 2 for power supply. The heating element is embedded in the microporous ceramic body 1 on the side facing the inner wall of the through hole 11 of the microporous ceramic body 1, and the side away from the inner wall of the through hole 11 is exposed in the through hole 11, so that the heating element can be in close contact with the microporous ceramic body 1, and can fully heat the mist particles passing through the through hole 11 to ensure the stability of the mist particles. The protruding structures at the upper and lower ends are embedded in the microporous ceramic body 1, so that the heating element 2 is stably fixed in the through hole 11 of the microporous ceramic body 1. In the long-term use tracking, this solution is prone to problems with poor atomization uniformity and stability. After disassembly and research, it was found that the middle part of the heating element 2 has extremely low heat generation and occupies a large area, resulting in insufficient connection between the heating element 2 and the microporous ceramic body 1. Under the action of long-term thermal expansion and contraction, some parts of the heating element 2 are separated from the microporous ceramic body 1. The separated part has a poor heating effect on the microporous ceramic body 1, and the atomization effect of the corresponding part will be reduced, while the part that has not been separated maintains the original atomization effect, resulting in uneven heating and atomization of the microporous ceramic atomization core as a whole.
[0034] For more information, please refer to Figures 2 to 8 The microporous ceramic atomizer core provided in the embodiment of the present application is now described. The microporous ceramic atomizer core comprises:
[0035] The microporous ceramic body 1 is provided with a through hole 11;
[0036] The heating element 2 includes a first heating portion 21, a second heating portion 22 and an intermediate connecting portion 23 located between the first heating portion 21 and the second heating portion 22. The first heating portion 21 and the second heating portion 22 are both connected to the microporous ceramic body 1 and exposed in the through hole 11. The intermediate connecting portion 23 has a first protruding structure 231, and the first protruding structure 231 is at least partially embedded in the microporous ceramic body 1.
[0037] The material of the microporous ceramic body 1 is microporous ceramic with a large number of tiny pores. After the liquid contacts the microporous ceramic body 1, it can penetrate into the microporous ceramic body 1 along the tiny pores. The heating element 2 is used to generate heat by electricity and transfer the heat to the microporous ceramic body 1. When the microporous ceramic body 1 is heated, the liquid inside it can evaporate quickly and enter the through hole 11 of the microporous ceramic body 1 to form atomized particles. The atomized particles can flow out, be absorbed or extracted through the through hole 11. The first heating part 21 and the second heating part 22 are both connected to the microporous ceramic body 1 and exposed in the through hole 11. They can be in close contact with the microporous ceramic body 1 to fully heat the microporous ceramic body 1, and can also fully heat the mist particles passing through the through hole 11 to ensure the stability of the mist particles. The finished appearance of the microporous ceramic atomization core can be seen in Figure 5 .
[0038] In this embodiment, the heating element 2 is divided into a first heating part 21 and a second heating part 22, and the first heating part 21 and the second heating part 22 are connected by an intermediate connecting part 23, and the intermediate connecting part 23 is embedded in the microporous ceramic body 1 through the first protruding structure 231 thereon. The first heating part 21 and the second heating part 22 can be arranged close to the inner wall of the through hole 11 of the microporous ceramic body 1, or they can be directly embedded in the microporous ceramic body 1 on one side of the microporous ceramic body 1, so that the first heating part 21 and the second heating part 22 are tightly connected to the microporous ceramic body 1, which is convenient for heat transfer. The first protruding structure 231 can be formed by the protrusion of the intermediate connecting part 23 itself, or it can be formed by a protruding part separately arranged on the intermediate connecting part 23. The first protruding structure 231 can be partially embedded in the microporous ceramic body 1, or it can be fully embedded in the microporous ceramic body 1. Compared with the integral heating part in the past, the heating element 2 of this embodiment can enhance the bonding strength between the heating element 2 and the microporous ceramic body 1 through the first protruding structure 231 located between the first heating element 21 and the second heating element 22. While maintaining the heating of the through hole 11 by the first heating element 21 and the second heating element 22, the first heating element 21 and the second heating element 22 are prevented from separating from the microporous ceramic body 1. Therefore, the heating of the microporous ceramic body 1 by the heating element 2 always maintains the original uniform state, avoiding the problem of uneven heating and atomization of the microporous ceramic atomization core as a whole.
[0039] See also Figure 3-Figure 4 as well as Figure 6-Figure 8 In one embodiment of the present application, an edge connection portion 24 is provided on the side of the first heating portion 21 facing away from the middle connection portion 23 and the side of the second heating portion 22 facing away from the middle connection portion 23. The edge connection portion 24 has a second protruding structure 241, and the second protruding structure 241 is at least partially embedded in the microporous ceramic body 1.
[0040] The first protruding structure 231 is embedded in the microporous ceramic body 1, and the second protruding structure 241 arranged on the edge connection part 24 is also embedded in the microporous ceramic body 1. It can be seen that the protruding direction of the second protruding structure 241 is roughly the same as or at least partially the same as that of the first protruding structure 231. The second protruding structure 241 can be formed by the protrusion of the edge connection part 24 itself, or it can be formed by a protruding component additionally arranged on the edge connection part 24. The second protruding structure 241 can be partially embedded in the microporous ceramic body 1, or it can be fully embedded in the microporous ceramic body 1. The second protruding structure 241 can cooperate with the first protruding structure 231, so that both sides of the first heating part 21 and the second heating part 22 have a structure that is stably embedded in the microporous ceramic body 1, thereby further preventing the first heating part 21 and the second heating part from being separated from the microporous ceramic body 1.
[0041] See also Figure 3 , Figure 4 , Figure 6 and Figure 8 In one embodiment of the present application, the edge connecting portion 24 includes a second connecting rod 242 , one end of the second connecting rod 242 is connected to the first heating portion 21 or the second heating portion 22 , and the other end is bent to form a second protruding structure 241 .
[0042] In this embodiment, the edge connection part 24 adopts a second connection rod 242, and the second connection rod 242 is connected to the first heating part 21 or the second heating part 22. Specifically, the second connection rod 242 located on one side of the first heating part 21 is connected to the first heating part 21, and the second connection rod 242 located on one side of the second heating part 22 is connected to the second heating part 22. The second connection rod 242 can be connected to the first heating part 21 or the second heating part 22 by welding or the like, or can be integrally formed on the first heating part 21 or the second heating part 22. The second protruding structure 241 can be formed by bending the second connection rod 242 to be embedded in the microporous ceramic body 1.
[0043] See also Figure 3 , Figure 4 , Figure 6 and Figure 8In one embodiment of the present application, the middle connecting portion 23 includes a first connecting rod 232, the two ends of the first connecting rod 232 are respectively connected to the first heating portion 21 and the second heating portion 22, and the first connecting rod 232 is bent to form a first protruding structure 231. In this embodiment, the edge connecting portion 24 adopts a second connecting rod 242, and the first connecting rod 232 itself is bent to form the first protruding structure 231. When the first connecting rod 232 is bent to form the first protruding structure 231, there is no need to set a protruding component on the first connecting rod 232 as the first protruding structure 231, which can simplify the structure and reduce material costs. The bending process of the first connecting rod 232 is also very simple, which can improve the delivery efficiency.
[0044] See also Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 In one embodiment of the present application, the first connecting rod 232 is connected to an anchor, and the anchor is embedded in the microporous ceramic body 1. The contact area between the first connecting rod 232 and the microporous ceramic body 1 is relatively small. In addition, the two ends of the first connecting rod 232 are respectively connected to the first heating part 21 and the second heating part 22, and even the heating body 2 is made of the same material as a whole. The first connecting rod 232 itself will also generate a certain amount of heat. The temperature difference between the hot state and the cold state of the first connecting rod 232 is relatively large, and it is relatively easier to affect the combination of the first protruding structure 231 and the microporous ceramic body 1.
[0045] Therefore, in this embodiment, an anchor is also provided on the first connecting rod 232. The anchor may be a sheet-shaped, straight rod-shaped, hook-shaped or other structure. The anchor can improve the degree of bonding between the first connecting rod 232 and the microporous ceramic body 1, thereby ensuring the heating effect of the first heating part 21 and the second heating part 22 on the microporous ceramic body 1.
[0046] See also Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8In one embodiment of the present application, the anchor is a convex tooth 233, and a plurality of convex teeth 233 are connected to at least one side of the first connecting rod 232, and the plurality of convex teeth 233 are arranged along the length direction of the first connecting rod 232. The convex teeth 233 can specifically be in the form of sharp teeth, square teeth, arc-shaped teeth, etc., and can be connected to the first connecting rod 232 by welding, integral molding, etc. The convex teeth 233 can exist only on one side of the first connecting rod 232, or on both sides of the first connecting rod 232. The connection strength enhanced by a single convex tooth 233 is limited, and therefore, a plurality of convex teeth 233 are provided on the first connecting rod 232, and the plurality of convex teeth 233 are arranged along the length direction of the first connecting rod 232, so as to enhance the overall connection tightness between the first connecting rod 232 and the microporous ceramic body 1.
[0047] See also Figure 8 In one embodiment of the present application, the first heating portion 21 and the second heating portion 22 each include a plurality of first rod segments 201, a plurality of second rod segments 202, and a plurality of third rod segments 203, the first rod segments 201 are parallel to the second rod segments 202, the third rod segments 203 are perpendicular to the first rod segments 201, the first rod segments 201 and the second rod segments 202 are alternately arranged, and the third rod segments 203 are connected between adjacent first rod segments 201 and second rod segments 202.
[0048] The first heating part 21 and the second heating part 22 in this embodiment include three rod segments, namely the first rod segment 201, the second rod segment 202 and the third rod segment 203. The first rod segment 201 is parallel to the second rod segment 202 and perpendicular to the third rod segment 203. The third rod segment 203 is connected between the adjacent first rod segments 201 and the second rod segment 202, so that the positions of the adjacent first rod segments 201 and the second rod segments 202 in the extension direction of the third rod segment 203 are different, so that the first rod segment 201, the second rod and the third rod segment 203 form a concave-convex fold line structure with a 90° bending angle, which can greatly increase the contact area between the first heating part 21, the second heating part 22 and the microporous ceramic body 1, and heat the microporous ceramic body 1 and the inside of the through hole 11 more evenly. In addition to the scheme of this embodiment, the first heating part 21 and the second heating part 22 can also adopt Figure 2 The fold line structure shown and other structural forms such as heating plates.
[0049] See also Figure 7 and 8 In one embodiment of the present application, the first rod segment 201 of the first heating part 21 is arranged toward the second heating part 22, and the first rod segment 201 of the second heating part 22 is arranged toward the first heating part 21, one end of the intermediate connecting part 23 is connected to the middle part of the first rod segment 201 of the first heating part 21, and the other end is connected to the middle part of the first rod segment 201 of the second heating part 22.
[0050] In the present embodiment, the first rod segment 201 of the first heating part 21 faces the second heating part 22, and the first rod segment 201 of the second heating part 22 faces the first heating part 21, that is, the first rod segments 201 of the first heating part 21 and the second heating part 22 are arranged opposite to each other, and the two ends of the intermediate connecting part 23 are respectively connected to the middle of the corresponding first rod segment 201. Compared with being connected to other positions, on the one hand, the force-bearing performance is better, which is beneficial to reducing the adverse effects of thermal expansion and contraction stress. On the other hand, the heat dissipation can be more uniform, thereby improving the uniformity of heat transfer from the first heating part 21 and the second heating part 22 to the microporous ceramic body 1.
[0051] See also Figure 7 and 8 In one embodiment of the present application, a side of the first heating portion 21 away from the middle connecting portion 23 and a side of the second heating portion 22 away from the middle connecting portion 23 are both provided with an edge connecting portion 24, and the edge connecting portion 24 has a second protruding structure 241, and the second protruding structure 241 is at least partially embedded in the microporous ceramic body 1;
[0052] The second rod segment 202 of the first heating part 21 faces away from the second heating part 22 , and the second rod segment 202 of the second heating part 22 faces away from the first heating part 21 . The middle of the second rod segment 202 of the first heating part 21 and the middle of the second rod segment 202 of the second heating part 22 are both connected with edge connecting parts 24 .
[0053] The heating element 2 of this embodiment is provided with an edge connection part 24, and the second protruding structure 241 of the edge connection part 24 is embedded in the microporous ceramic body 1 to improve the tightness of the combination of the heating element 2 and the microporous ceramic body 1. The second rod segment 202 of the first heating part 21 faces away from the second heating part 22, and the second rod segment 202 of the second heating part 22 faces away from the first heating part 21, that is, the second rod segments 202 of the first heating part 21 and the second heating part 22 are arranged opposite to each other, and can be used to connect the edge connection part 24. The edge connection part 24 is connected to the middle part of the second rod segment 202. On the one hand, the force-bearing performance is better, which is conducive to reducing the adverse effects of thermal expansion and contraction stress. On the other hand, it can make the heat dissipation more uniform, and improve the uniformity of heat transfer from the first heating part 21 and the second heating part 22 to the microporous ceramic body 1.
[0054] The number of through holes 11 of the microporous ceramic body 1 can be one or more. If the number of through holes 11 of the microporous ceramic body 1 is more than one, a corresponding heating element 2 can be provided in each through hole 11, or the same heating element 2 can heat multiple through holes 11 at the same time.
[0055] The present application also provides a heating element 2, which is the heating element 2 in the above-mentioned microporous ceramic atomization core. The heating element 2 can be combined with the microporous ceramic body 1, and the assembled microporous ceramic atomization core can prevent the first heating part 21 and the second heating part 22 from separating from the microporous ceramic body 1 while maintaining the heating of the through hole 11 by the first heating part 21 and the second heating part 22, so that the heating of the microporous ceramic body 1 by the heating element 2 always maintains the original uniform state, preventing the problem of uneven heating and atomization of the microporous ceramic atomization core as a whole.
