Technical Field
The invention belongs to the field of electronic atomization, and particularly relates to an atomization core, an electronic cigarette and a manufacturing method of the atomization core.
Background
The atomizing core of the electronic cigarette comprises two parts: a liquid-conducting body that permeates and retains the atomized liquid (also known as an atomized precursor, an atomized medium, or tobacco tar), and electronics that evaporate or disperse the atomized liquid. The porous ceramic is made from ceramic powder blank through extrusion forming and low-temperature sintering, is high-temperature resistant and has few metal pollutants, and is an ideal liquid guide material. The prior ceramic atomizing core is generally structured by printing an electric heating circuit on a porous ceramic liquid-conducting body.
When the ceramic blank is extruded and formed, the edge stress is large, the center stress is small, and the average pore diameter, the pore diameter distribution (pore distribution) and the porosity of each part in the porous ceramic liquid guide body are inconsistent. The porosity of the uneven distribution inevitably causes the inconsistent passing speed and flow of the tobacco tar when the tobacco tar flows through the ceramic body, and when a printed circuit generates heat, the ceramic at the position with smaller speed and flow is easily dried and burnt, the overall taste is not good, and harmful substances are easily generated.
In addition, in the ceramic forming control process, if the pore of the ceramic body is too large, oil is guided smoothly, but oil leakage is easy to occur; if the pore space of the ceramic body is too small, the problem of oil leakage is solved, but the oil guide is not smooth, and the dry burning is easy.
In addition, in the process of heating the printed circuit at high temperature for a long time, sugar substances in the tobacco tar are heated and then attached to the surface of the printed circuit, so that carbon is easily deposited.

The first conducting liquid 110 is used to contact the atomized liquid. The atomization assembly 130 includes an energy conversion portion located above the second liquid guide 120 and isolated from the first liquid guide 110 to atomize the atomized liquid adsorbed by the second liquid guide 120.

Specifically, the average pore size of the pores in first liquid conducting body 110 is larger than the average pore size of the pores in second liquid conducting body 120. The average pore size of the second liquid guiding body 120 is small, so the capillary force is large, the atomized liquid tends to permeate from the first liquid guiding body 110 to the second liquid guiding body 120, so that the atomized liquid is sufficiently supplied and the dry burning phenomenon is reduced, and the atomized liquid is not easy to leak from the second liquid guiding body 120. The first liquid conducting body 110 is isolated from the atomizing assembly and is preferably leak-proof, and may be sealed from the surfaces of the atomizing liquid and the second liquid conducting body by a housing or coating.
Specifically, the adsorption capacity of the first liquid conducting body 110 is greater than the adsorption capacity of the second liquid conducting body 120. The second liquid guiding body 120 has a smaller adsorption capacity, thus having a smaller volume and a simpler structure, and the porosity uniformity is larger under the same preparation process condition, thereby further reducing the dry burning phenomenon.

One of the forming processes is die-casting metal particles, and the size of the metal particles and the die-casting force are selected, so that the size of the pores among the metal particles is controlled, and the consistent porosity of each part of a formed body is ensured. In another forming process, micropores are formed on a metal substrate material, and the diameters of the micropores and the distance between adjacent micropores are selected, so that the porosity is controlled, and the uniform and controllable porosity of each part of the formed body is ensured. The second liquid guiding body 120 is made of a porous ceramic material, and the preparation steps include: preparing ceramic powder, mixing the raw materials, molding, drying and sintering at low temperature.
