However, the existing ceramic atomization core has a relatively thick wall thickness, resulting in low heating efficiency. However, an overly thin wall thickness will cause a reduction in the strength of the ceramic atomization core, and it will break during use. Summary of the Utility Model

[0026] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present utility model are only based on the accompanying drawings of the present utility model, and they do not specifically limit the present utility model.

[0027] As Figures 2 to 7 shown, the embodiment of the present utility model provides a ceramic atomization core, which includes a ceramic atomization core substrate. The ceramic atomization core substrate includes an atomization end 1 and an oil absorption end 2. The oil absorption end 2 is recessed towards the atomization end 1 to form an oil storage cavity 3. A side wall 4 is provided around between the oil absorption end 2 and the atomization end 1. A strengthening structure 5 is provided inside the oil storage cavity 3. The strengthening structure 5 includes a plurality of strengthening ribs, and the strengthening ribs are connected to each other to form a three-dimensional network body. By providing the strengthening structure 5, the overall strength of the ceramic atomization core is improved.

[0028] The surface of the oil storage cavity 3 in contact with the e-liquid is the oil storage surface 31, and the side of the atomization end 1 away from the oil storage cavity 3 is the atomization surface. Among them, the three-dimensional network body is arranged inside the oil storage cavity 3 and connected to the oil storage surface 31 to form a plurality of channels 51 for the e-liquid to pass through. The e-liquid can pass through the channels 51, part of it seeps into the strengthening structure 5 and then enters the atomization end 1, and part directly enters the atomization end 1, thereby increasing the contact area between the e-liquid and the ceramic atomization core.

[0029] In order to facilitate the increase of the e-liquid seepage area, the strengthening ribs are provided with through holes, and the through holes penetrate the strengthening ribs and are communicated with the channels 51. Specifically, the through holes are micropores, and the pore diameter is 1 μm to 100 μm. Exemplarily, it is 5 μm, 10 μm, 20 μm, 50 μm or 80 μm, but not limited thereto. The setting of the micropores is beneficial to balance the liquid locking ability and the seepage ability, which can not only ensure the seepage rate of the e-liquid, but also prevent the e-liquid from leaking.

[0030] Since a reinforcing structure 5 is provided inside the oil storage cavity 3 of the ceramic atomizing core, an atomizing core with a thinner wall thickness can be designed, shortening the liquid leakage path of the e-liquid while ensuring the overall strength of the ceramic atomizing core, thereby improving the liquid leakage efficiency of the e-liquid. The wall thickness of the side wall 4 of the ceramic atomizing core is 0.5 mm to 2 mm, and exemplarily, it is 0.8 mm, 1 mm, 1.2 mm, 1.5 mm or 1.8 mm, but not limited thereto. Preferably, the wall thickness of the side wall 4 of the ceramic atomizing core is 0.7 mm to 1.2 mm.

[0031] The width of the reinforcing rib is 0.1 mm to 10 mm, and exemplarily, it is 0.5 mm, 1 mm, 2 mm, 5 mm or 8 mm, but not limited thereto. Specifically, the cross-section of the reinforcing rib can be one of a circle, a triangle, a trapezoid, a rectangle, and a semi-circle. Correspondingly, the width of the reinforcing rib can be defined as the diameter of the circle, the diameter of the circumscribed circle of the triangle, the length of the longer base of the trapezoid, the length of the long side of the rectangle, and the diameter of the semi-circle. The specific cross-sectional shape and width can be improved according to actual requirements, with high design flexibility.

[0032] The reinforcing structure 5 includes multiple groups of reinforcing units 52 arranged in a repeated array inside the oil storage cavity 3. Each group of reinforcing units 52 includes a first reinforcing rib 521, a second reinforcing rib 522, a third reinforcing rib 523, and a fourth reinforcing rib 524. The first reinforcing rib 521, the second reinforcing rib 522, the third reinforcing rib 523, and the fourth reinforcing rib 524 are connected to each other to form a three-dimensional network structure. By repeating the array of the same reinforcing units 52, the overall strength of the ceramic atomizing core is improved, and the repeated array is also convenient for structural design and improving the force uniformity. Specifically, the number of reinforcing units and the number of reinforcing ribs in each group of reinforcing units can be increased or decreased according to actual requirements.

[0033] The included angle between the first reinforcing rib 521, the second reinforcing rib 522, the third reinforcing rib 523, and the fourth reinforcing rib 524 is 60° to 120°. Optimally, the included angle between the first reinforcing rib 521, the second reinforcing rib 522, the third reinforcing rib 523, and the fourth reinforcing rib 524 is 90°, which can achieve the most stable three-dimensional network structure.

[0034] Such as Figure 6 and Figure 7As shown in the figure, in order to further increase the strength of the opening of the oil absorption end 2 of the ceramic atomization core matrix, an oil absorption end reinforcing rib 53 is provided on the side of the oil storage cavity 3 away from the atomization end 1. The oil absorption end reinforcing rib 53 has at least one plane, and the plane of the oil absorption end reinforcing rib 53 is arranged outward so that the plane of the oil absorption end reinforcing rib 53 is flush with the outer surface of the oil absorption end 2. Specifically, the oil absorption end reinforcing rib 53 includes a fifth reinforcing rib 531 and a sixth reinforcing rib 532. A plurality of the fifth reinforcing ribs 531 and the sixth reinforcing ribs 532 are arranged crosswise to form a two-dimensional network structure. Preferably, the fifth reinforcing rib 531 and the sixth reinforcing rib 532 are perpendicular to each other to improve stability. The number of the fifth reinforcing rib and the sixth reinforcing rib can be increased or decreased according to actual needs.

[0035] In addition, a heating component is provided on the atomization surface of the ceramic atomization core matrix. After the heating component is powered on, it generates heat energy to heat the e-liquid to form smoke, realizing the atomization of the e-liquid.

[0036] The ceramic atomization core matrix provided by the present utility model is integrally formed by 3D printing. Using 3D printing technology to prepare the ceramic atomization core, specific reinforcing structures can be set during the modeling process to meet different requirements, and the design flexibility is high. The ceramic atomization cores of the prior art usually adopt die pressing technology for processing. To improve the shape of the ceramic atomization core, the mold needs to be improved, which increases the process. However, 3D printing can not only design the ceramic atomization core according to requirements, but also be applicable to various ceramic powders such as alumina, silica, zirconia, feldspar, quartz sand, diatomaceous earth, and kaolin. The prepared ceramic atomization core is not affected by the processing technology and has a wide range of applications.

[0037] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
