Abstract

The invention discloses a porous ceramic heating element which comprises a porous ceramic body, at least one porous ceramic tube and at least one metal heating core, the porous ceramic body is provided with at least one through hole, the porous ceramic tube is installed in the through hole, and the metal heating core is installed in the porous ceramic tube. The aperture of the porous ceramic body is larger than that of the porous ceramic tube. Multiple layers of ceramic bodies with different pore diameters are adopted as oil guide paths, atomization liquid is guided in through the porous ceramic body with the large external pore diameter, heating atomization is conducted through the porous ceramic pipe with the large porosity and the small pore diameter in the middle layer, distribution of the atomization liquid around the interior of the metal heating core is effectively reduced, a proper amount of atomization liquid is atomized, and the atomization effect is improved. The probability of internal carbon deposition is reduced; by utilizing the hindering effect of the porous ceramic on the temperature, the middle layer adopts the porous ceramic tube with high porosity, and the temperature field near the metal heating core can be homogenized by regulating and controlling the porosity and the pore diameter of the porous ceramic layer.

Description

technical field [0001] The present invention relates to the technical field of atomizers, in particular to a porous ceramic heating element and a preparation method thereof. Background technique [0002] With the development of society and the advancement of science and technology, electronic atomization products have been more and more widely used. At present, the heating elements used in electronic atomizers have some common problems, such as single porosity, small heating area, uneven temperature distribution, carbon deposits on heating wires, and porous ceramic carbon deposits to block pores. The effect of atomization is poor, which in turn affects the precise control of atomization temperature and atomization components, and ultimately affects the user experience. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a solution for the problems of single porosity, small heating area, uneven temperature distribution, carbon depositi...
