[0002] At present, an atomization core generally includes a ceramic matrix and a ceramic heating element disposed on the ceramic matrix. Among them, in order to ensure that the ceramic matrix has a certain strength so as not to break during the assembly process, the thickness of the ceramic matrix is designed to be relatively thick. However, the relatively thick ceramic matrix will increase the liquid transmission path or resistance of the oil storage chamber liquid, resulting in insufficient liquid supply and generating a burnt smell.

[0003] In the related art, in order to solve the above defects, the thickness of the matrix is made smaller, or a liquid absorption groove is provided on the side of the ceramic matrix facing away from the heating element, thereby reducing the liquid transmission path to the surface where the heating element is located. In this way, both the ceramic strength and the liquid supply speed are ensured. However, in the face of atomizing viscous liquids, the bubbles for the heating element to ventilate will be blocked in the liquid absorption groove of the heating element. Due to the large viscosity, the bubbles are extremely difficult to float, resulting in blocking the liquid supply channel, thereby leading to insufficient liquid supply and generating a burnt smell.

[0035] Embodiment:

[0036] Please refer to Figures 1 to 7, an embodiment of the present utility model provides an atomization component, which includes a liquid guide body 1 and a heating element 2. The liquid guide body 1 has an atomization surface 11; the heating element 2 is fixed to the liquid guide body 1, and the heating element 2 has a first heating part and a second heating part connected from the first heating part into the liquid guide body 1, and the heating power of the first heating part is greater than that of the second heating part. The first heating part is attached to the atomization surface 11, the second heating part is embedded in the liquid guide body 1, and the heating power of the second heating part is 10%-30% of the total heating power of the heating element 2.

[0037] Since the second heating part of the heating element 2 is embedded in the liquid guide body 1, when the atomization component is heated, the heat generated by the second heating part can preheat the viscous atomization liquid, reduce the viscosity of the atomization liquid, thereby improving the liquid guiding rate and avoiding the generation of burnt smell. Moreover, the second heating part whose heating power of the first heating part is greater than that of the second heating part, and the heating power of the second heating part is 10%-30% of the total heating power of the heating element 2, which can not only prevent the preheating temperature from being too high to generate too many atomization bubbles, but also ensure that most of the heat generated by the heating element 2 is used to heat the atomization liquid to generate aerosol, improving the energy utilization rate.

[0038] It should be noted that the liquid guide body 1 can be a porous ceramic body, and the porous ceramic body has a certain thickness to ensure the structural strength, and the atomization surface 11 of the liquid guide body 1 is a plane. The first heating part is used to heat the atomization liquid to generate aerosol, and the second heating part is used to preheat the atomization liquid. As an example, the heating power of the second heating part is 10%, 13%, 18%, 20%, 26%, 30%, etc. of the total heating power of the heating element 2.

[0039] The heating element 2 includes a plurality of heating units connected in series in sequence. At least part of at least one heating unit is attached to the atomization surface 11 to form a first heating part, and at least part of at least one heating unit is embedded in the liquid guide body 1 to form a second heating part, so that the heating element 2 can not only heat the atomization liquid to generate aerosol, but also preheat the atomization liquid.

[0040] According to actual needs, the number of heating units can be two, three, four, six, seven, etc. The same heating unit can be provided with only a first heating part, or only a second heating part, or the same heating unit is provided with both a first heating part and a second heating part. For example, there are six heating units, three of which are provided with both a first heating part and a second heating part, and the other three heating units are only provided with a first heating part to ensure that the heating power of the second heating part is 10%-30% of the total heating power of the heating element 2.

[0041] The heating unit includes a plurality of heating circuits connected in parallel. One heating circuit of at least one heating unit is disposed on the atomization surface 11 to form a first heating portion, and one heating circuit of at least one heating unit is embedded in the liquid guide 1 to form a second heating portion, so that the heating body 2 can both heat the atomized liquid to generate an aerosol and preheat the atomized liquid.

[0042] According to actual needs, the heating circuits of the heating unit can be provided with two, three, four, etc. For example, one heating unit is provided with two heating circuits, one of which is disposed on the atomization surface 11, and one heating circuit of another heating unit is embedded in the liquid guide 1; or, both heating circuits are disposed on the atomization surface 11; or both heating circuits are embedded in the liquid guide 1 to ensure that the heating power of the second heating portion is 10%-30% of the total heating power of the heating body 2.

[0043] Please refer to Figure 2 、 Figure 3 and Figure 4 In some embodiments, the heating body 2 includes a plurality of first heating units 21 and second heating units 22 connected in series alternately in sequence, which can make the first heating units 21 and the second heating units 22 be regularly distributed, so that the heating of the heating body 2 is relatively uniform. The second heating unit 22 includes a first line 221 and a second line 222 connected in parallel. The first line 221 is disposed on the atomization surface 11, and the second line 222 is embedded in the liquid guide 1; wherein, the first line 221 is the first heating portion, the second line 222 is the second heating portion, the second line 222 is the outer line in the second heating unit 22, and the second line 222 is embedded in the liquid guide 1 through bending. The heating power of the first line 221 is greater than that of the second line 222 to ensure that the heating power of the first heating portion is greater than that of the second heating portion, so that most of the heat generated by the heating body 2 is used to heat the atomized liquid to generate an aerosol.

[0044] According to actual needs, the number of both the first heating units 21 and the second heating units 22 can be two, three, four, etc. For example, three first heating units 21 and three second heating units 22 are connected in series alternately in sequence. The bending portion of the second line 222 can be processed by a semi-etching process into a bending mark to facilitate subsequent bending processing.

[0045] Please refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 The first heating unit 21 includes a third line 211 and a fourth line 212 connected in parallel. Both the third line 211 and the fourth line 212 are disposed on the atomization surface 11, wherein, both the third line 211 and the fourth line 212 are the first heating portions, that is, the first heating unit 21 is all used to heat the atomized liquid, which can improve the energy utilization rate of the heating body 2.

[0046] Please refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 ,the first heating unit 21 extends along the first direction of the atomization surface 11 and is spaced apart along the second direction of the atomization surface 11, and the second heating unit 22 extends along the second direction of the atomization surface 11; wherein, the first direction intersects with the second direction.

[0047] In some specific embodiments, the first direction is perpendicular to the second direction, such that the second heating part is perpendicular to the atomization surface 11, which is beneficial for the second heating part to be embedded into the liquid guide 1. As an example, the liquid guide 1 has a width direction and a length direction parallel to the atomization surface 11. Among them, one of the first direction and the second direction can be the length direction of the liquid guide 1, and the other is the width direction of the liquid guide 1.

[0048] It can be understood that the included angle between the first direction and the second direction can also be 30°, 60°, 80°, etc.

[0049] Please refer to Figure 2 and Figure 3 ,in a specific example, the heating element 2 can include three first heating units 21 and three second heating units 22. The three first heating units 21 and the three second heating units 22 are alternately connected in series in sequence, and the three first heating units 21 extend along the first direction of the atomization surface 11 and are spaced apart along the second direction of the atomization surface 11. The three second heating units 22 extend along the second direction of the atomization surface 11 and are embedded into the liquid guide 1. Among them, the first heating unit 21 includes a third circuit 211 and a fourth circuit 212 connected in parallel. Both the third circuit 211 and the fourth circuit 212 are disposed on the atomization surface 11 to form a first heating part; the second heating unit 22 includes a first circuit 221 and a second circuit 222 connected in parallel. The first circuit 221 is disposed on the atomization surface 11 to form a first heating part, and the second circuit 222 is embedded into the liquid guide 1 to form a second heating part. Among them, the heating power of the first heating part is greater than that of the second heating part, and the heating power of the second heating part is 10%-30% of the total heating power of the heating element 2.

[0050] It should be noted that by adjusting the materials, line widths, line lengths, and shapes of the first circuit 221, the second circuit 222, the third circuit 211, and the fourth circuit 212, heating elements 2 with different resistances can be formed, thereby controlling the percentage of the heating power of the second heating part in the total heating power of the heating element 2. Preferably, the line width at the connection of the first heating unit 21 and the second heating unit 22 is set wider to prevent local overheating at the connection from causing a burnt smell. For example:

[0051] By controlling the line lengths and line widths of the first line 221 and the second line 222, wherein the line length of the first line 221 in the second heating unit 22 is set to 4.9 mm and the line width is set to 0.07 mm, and the line length of the second line 222 is set to 3.4 mm and the line width is set to 0.08 mm, so that the heating power of the second heating part is about 17.5% of the total heating power of the heating element 2.

[0052] Or, as Figure 4 shown, by controlling the shape of the second line 222, wherein the second line 222 in the second heating unit 22 is set as a broken line segment, so as to increase the effective length of the second line 222 and improve the heating power of the second heating part.

Among them, both the first line 221 and the second line 222 are the second heating elements 2, and the arrangement of the first line 221 and the second line 222 facilitates bending of the second heating unit 22. According to actual needs, the first heating unit 21 includes a third line 211 and a fourth line 212 that are connected in parallel, and both the third line 211 and the fourth line 212 are disposed on the atomization surface 11; the third unit includes a fifth line 231 and a sixth line 232 that are connected in parallel, and both the fifth line 231 and the sixth line 232 are disposed on the atomization surface 11.
