Today’s Patent – Ceramic atomization Core having metal coating layer

The said invention (EP4449918A1) was invented by Weili LiuFei Qin, patented by USPTO on 17-01-2022. Currently, it stands assigned to Haining New Natao Technology Co Ltd.

Electronic atomization devices, such as electronic cigarettes, rely on atomization cores for converting liquid into aerosol. Traditional atomization cores use resistance heating wires, heating pads, or printed circuit heating methods. However, these methods face limitations such as small effective atomization areas, uneven heating, carbon deposition, liquid leakage, and the risk of circuit breakage due to thermal stress. Additionally, ceramic-based atomization cores suffer from temperature gradients and ineffective atomization efficiency, negatively impacting product consistency and user experience. These limitations necessitate a more reliable and efficient solution for heating and atomizing liquids.

The invention introduces a ceramic atomization core with a nanoscale metal coating layer that addresses these limitations. This core features a porous ceramic body with a metal coating layer designed for uniform heating, enhanced atomization efficiency, and reduced risks of carbon deposition and liquid leakage. The coating layer includes a heating layer with through-film holes that maximize the atomization area and ensure consistent aerosol release. Transition layers and protective layers further enhance durability and performance. By enabling uniform heat distribution and eliminating circuit breakage risks, this invention significantly improves product consistency, safety, and the overall vaping experience.
