Abstract

The invention discloses an atomizing core structure based on an MEMS silicon-based heating sheet, which comprises a silicon-based heating sheet and a porous ceramic core. The silicon-based heating sheet comprises a heating wire and a silicon-based substrate, and the heating wire is manufactured on the surface of the silicon-based substrate. Atomizing micropores arranged in an array are arranged on the silicon-based substrate, the silicon-based substrate is fixedly arranged on the porous ceramic core, and the atomizing micropores are communicated with the porous ceramic core. The invention further discloses a manufacturing method of the atomizing core structure based on an MEMS silicon-based heating sheet. Compared with the prior art, liquid leakage of the atomizing core is avoided, the machining difficulty is reduced, the yield is increased, the atomizing heating area of the atomizing core is increased, the temperature uniformity is improved, the atomizing amount is increased, and dry burning is reduced.

Description

technical field [0001] The invention belongs to the field of liquid heating atomizing cores, and in particular relates to an atomizing core structure based on a MEMS silicon-based heating plate and a manufacturing method thereof. Background technique [0002] As the core component of liquid atomizing products, the heating atomizing core is used to heat the liquid and make it emit in the form of mist aerosol. Liquid heating atomizing cores mainly include cotton-wrapped atomizing cores and porous ceramic atomizing cores. The metal heating wire in the cotton-covered atomizing core is in direct contact with the cotton core. At high temperatures, the metal components in the heating wire and the debris of the cotton core material may be carried by the aerosol formed by atomization and inhaled by the user, causing potential health problems. harm. At the same time, the non-uniform contact between the cotton core and the metal heating wire, uneven heating, and high-temperature carb...
