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.

[0032] See also Figure 1 and Figure 2 The heating component provided in the embodiment of the present application is now described. The heating component of this embodiment is used for a microporous ceramic atomization core, and the heating component includes:

[0033] The heating element comprises a first heating element 2a and a second heating element 2b, wherein the first heating element 2a and the second heating element 2b are arranged side by side;

[0034] The leads include a first lead 3a, a second lead 3b and a third lead 3c. The first lead 3a is arranged on a side of the first heating element 2a away from the second heating element 2b and is electrically connected to the first heating element 2a. The second lead 3b is located between the first heating element 2a and the second heating element 2b and is electrically connected to the first heating element 2a and the second heating element 2b respectively. The third lead 3c is located on a side of the second heating element 2b away from the first heating element 2a and is electrically connected to the second heating element 2b.

[0035] The heating element is used to generate heat after being energized, and the lead wire is used to provide power to the heating element. In this embodiment, the heating element includes a first heating element 2a and a second heating element 2b, and the first heating element 2a and the second heating element 2b can generate heat independently or simultaneously, and the first lead wire 3a, the second lead wire 3b and the third lead wire 3c can provide power for the heating of the heating element.

[0036] The heating component of this embodiment can realize multiple heating modes under the same power supply. The first lead 3a and the second lead 3b are respectively connected to the two ends of the power supply to make the first heating element 2a heat up; the second lead 3b and the third lead 3c are respectively connected to the two ends of the power supply to make the second heating element 2b heat up; the first lead 3a and the third lead 3c are respectively connected to the two ends of the power supply to make the first heating element 2a and the second heating element 2b heat up in series; the second lead 3b is connected to one end of the power supply and the first lead 3a and the third lead 3c are both connected to the other end of the power supply to make the first heating element 2a and the second heating element 2b heat up in parallel. Therefore, the heating component of this embodiment can realize a variety of heating powers only by simple power switching. Applying it to the microporous ceramic atomization core can provide different heating temperatures for the microporous ceramic atomization core, and can realize more diverse application scenarios.

[0037] For example, by adjusting the heating temperature of the microporous ceramic atomization core, the atomization rate can be adjusted to provide different atomization gears. When the required atomization amount is large, the first heating element 2a and the second heating element 2b can be adjusted to heat in parallel to provide the maximum heating amount. When the required atomization amount is small, the first heating element 2a can be adjusted to heat alone, the second heating element 2b can be adjusted to heat alone, or even the first heating element 2a and the second heating element 2b can be adjusted to heat in series.

[0038] For another example, by adjusting the heating temperature of the microporous ceramic atomization core, different atomization liquids can be better matched. Some liquids require a high atomization temperature, so the heating component can be adjusted so that the first heating element 2a and the second heating element 2b are heated in parallel. Some liquids require a low atomization temperature, so the heating component can be adjusted so that the first heating element 2a heats alone, the second heating element 2b heats alone, or even the first heating element 2a and the second heating element 2b heat in series, so that the same microporous ceramic atomization core can be used to match different atomization liquids.

[0039] See also Figure 1 and Figure 2 In one embodiment of the present application, the heating component further includes a connecting plate 4, the first heating element 2a and the second heating element 2b are connected via the connecting plate, and the second lead 3b is connected to the connecting plate.

[0040] The resistance of the lead wire needs to be much smaller than the resistance of the heating element in order for the heating element to work normally. Therefore, the materials of the lead wire and the heating element are usually different. The lead wire is usually connected to the heating element by welding or crimping. In addition, most of the lead wires are round, which causes the connection strength between the lead wire and the heating element to be usually weak. Using the second lead wire 3b to directly connect the first heating element 2a and the second heating element 2b together can easily cause damage to the connection between the second lead wire 3b and the first heating element 2a and the second heating element 2b, especially if Figure 3-6In the case where the installation state of the heating component shown needs to be curled, the connection damage of the second lead 3b will directly affect the transmission of current and the heating efficiency.

[0041] In this embodiment, the first heating element 2a and the second heating element 2b are connected by a connecting plate, so that the mechanical force between the first heating element 2a and the second heating element 2b is mainly borne by the connecting plate, and the second lead 3b is then connected to the connecting plate, so that the second lead 3b not only does not need to bear the mechanical force between the first heating element 2a and the second heating element 2b, but the connecting plate can also provide protection for the second lead 3b.

[0042] See also Figure 1 and 2 In one embodiment of the present application, the first heating element 2a, the connecting plate and the second heating element 2b are an integrally formed structure. Considering that the heating component structure of the microporous ceramic atomization core is relatively small as a whole, the processing difficulty of connecting the first heating element 2a and the second heating element 2b to the connecting plate by welding, bolting, etc. is relatively large. Therefore, in this embodiment, the first heating element 2a, the connecting plate and the second heating element 2b are an integrally formed structure. The three can usually be directly processed into one by stamping, cutting, etc., which can not only greatly reduce the difficulty of processing, but also make the connection between the first heating element 2a and the second heating element 2b no longer a weak link. The connecting plate and the first heating element 2a and the second heating element 2b are made of the same material, which can also provide a certain heating effect.

[0043] In one embodiment of the present application, the rated heating power of the first heating element 2a is different from the rated heating power of the second heating element 2b. As mentioned above, the two heating methods of the heating component include connecting the first lead 3a and the second lead 3b to the two ends of the power supply respectively, so that the first heating element 2a can generate heat; and connecting the second lead 3b and the third lead 3c to the two ends of the power supply respectively, so that the second heating element 2b can generate heat. If the rated heating power of the first heating element 2a and the second heating element 2b are the same, the heating power of the two heating methods is the same, but the heating positions are different. In this embodiment, the first heating element 2a and the second heating element 2b have different rated heating powers, which can make the two heating methods also have different heating powers, so that the heating component has more different heating powers to better adapt to different application scenarios.

[0044] See also Figure 2-6 In one embodiment of the present application, the first heating element 2a and the second heating element 2b each include 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 intermediate connecting portion 23 having a first protruding structure 231, and the first protruding structure 231 is used to be embedded in the microporous ceramic body 1;

[0045] The first heating portion 21 and the second heating portion 22 are both provided with edge connecting portions 24 on one side away from the middle connecting portion 23 . The edge connecting portion 24 has a second protruding structure 241 . The second protruding structure 241 is at least partially embedded in the microporous ceramic body 1 .

[0046] In this embodiment, the heating element is divided into a first heating portion 21 and a second heating portion 22, and the first heating portion 21 and the second heating portion 22 are connected by an intermediate connecting portion 23, and the intermediate connecting portion 23 is embedded in the microporous ceramic body 1 through the first protruding structure 231 thereon. The first heating portion 21 and the second heating portion 22 can be arranged close to 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 portion 21 and the second heating portion 22 are closely 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 portion 23 itself, or it can be formed by a protruding component additionally arranged on the intermediate connecting portion 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 heating portion in the integral form in the past, the heating element of this embodiment can enhance the degree of integration between the heating element and the microporous ceramic body 1 through the first protruding structure 231 located between the first heating portion 21 and the second heating portion 22.

[0047] The second protruding structure 241 provided on the edge connection portion 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 substantially 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 portion 24 itself, or it can be formed by a protruding component additionally provided on the edge connection portion 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 portion 21 and the second heating portion 22 are structurally stably embedded in the microporous ceramic body 1, thereby further preventing the first heating portion 21 and the second heating portion from being separated from the microporous ceramic body 1.

[0048] This embodiment can prevent the first heating part 21 and the second heating part 22 from being separated from the microporous ceramic body 1, so that the heating of the microporous ceramic body 1 by the heating element always maintains the original uniform state, preventing the problem of uneven heating and atomization of the entire microporous ceramic atomization core.

[0049] See also Figure 3 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 .

[0050] In this embodiment, the edge connection part 24 adopts a second connecting rod 242, and the second connecting rod 242 is connected to the first heating part 21 or the second heating part 22. Specifically, the second connecting rod 242 located on one side of the first heating part 21 is connected to the first heating part 21, and the second connecting rod 242 located on one side of the second heating part 22 is connected to the second heating part 22. The second connecting 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 connecting rod 242, and the second protruding structure 241 is used to be embedded in the microporous ceramic body 1.

[0051] See also Figure 3 In 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.

[0052] See also Figure 3 In one embodiment of the present application, at least one side of the first connecting rod 232 is connected with a plurality of protruding teeth 233, and the plurality of protruding teeth 233 are arranged along the length direction of the first connecting rod 232. The contact area between the first connecting rod 232 and the microporous ceramic body 1 is relatively small. In addition, the first connecting rod 232 has two ends connected to the first heating portion 21 and the second heating portion 22, respectively, and even the heating body 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.

[0053] In this embodiment, the first connecting rod 232 is provided with a plurality of convex teeth 233, which may be in the form of sharp teeth, square teeth, arc-shaped teeth, etc., and may be connected to the first connecting rod 232 by welding, integral molding, etc. The convex teeth 233 may exist only on one side of the first connecting rod 232, or may exist 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 tightness of the connection between the first connecting rod 232 and the microporous ceramic body 1 as a whole.

[0054] See also Figure 1 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.

[0055] 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 more evenly. In addition to adopting the solution 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.

[0056] In addition to the first heating element 2a and the second heating element 2b, the heating component of the present application can also be provided with more heating elements. Leads are provided on both sides of each heating element. At the same time, two adjacent heating elements share the leads, which can achieve more power changes and meet more application requirements.

[0057] On the basis of the above-mentioned heating component, the present application also provides a microporous ceramic atomization core, including a microporous ceramic body 1 and a heating component, wherein the heating component is arranged in the microporous ceramic body 1.

[0058] The microporous ceramic body 1 is made of microporous ceramic with a large number of tiny pores. After the liquid comes into contact with it, it can penetrate into the microporous ceramic body 1 along the tiny pores. The heating component is powered on to generate heat and transfer the heat to the microporous ceramic body 1. When the microporous ceramic body 1 is heated, the liquid inside it can quickly evaporate to form atomized particles.

[0059] The microporous ceramic atomizer core of the present embodiment can realize a variety of heating modes under the same power supply drive. The first lead 3a and the second lead 3b are respectively connected to the two ends of the power supply to make the first heating element 2a heat up; the second lead 3b and the third lead 3c are respectively connected to the two ends of the power supply to make the second heating element 2b heat up; the first lead 3a and the third lead 3c are respectively connected to the two ends of the power supply to make the first heating element 2a and the second heating element 2b heat up in series; the second lead 3b is connected to one end of the power supply, and the first lead 3a and the third lead 3c are both connected to the other end of the power supply to make the first heating element 2a and the second heating element 2b heat up in parallel. Therefore, the microporous ceramic atomizer core of the present embodiment can realize a variety of heating powers and provide different heating temperatures through simple power switching, which can realize more diverse application scenarios.

[0060] In such Figure 5-7 In the embodiment shown, the microporous ceramic body 1 has a through hole 11, and the first heating element 2a and the second heating element 2b are connected to the microporous ceramic body 1 and exposed in the through hole 11. They can not only be in close contact with the microporous ceramic body 1 to fully heat the microporous ceramic body 1, but also can fully heat the mist particles passing through the through hole 11 to ensure the stability of the mist particles.

[0061] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
