Atomization core, atomizer and electronic atomization device

Abstract

The invention relates to an atomization core, an atomizer and an electronic atomization device. The atomization core comprises a porous ceramic matrix and a heating element, wherein the porous ceramicmatrix comprises a liquid guide layer and a heat conduction layer; the heat conductivity of the heat conduction layer is greater than the heat conductivity of the liquid guide layer; the permeabilityof the liquid guide layer is higher than the permeability of the heat conduction layer; and the heating element is attached to the heat conduction layer. Due to the fact that the heat conduction layer is arranged on the liquid guide layer and the heat conductivity of the heat conduction layer is much higher than the heat conductivity of the liquid guide layer, when the heating element works, heatgenerated by the heating element is rapidly conducted to each area of the heat conduction layer through the heat conduction layer, so that the dry burning phenomenon caused by the local high temperature of the porous ceramic matrix is effectively prevented. Meanwhile, the permeability of the heat conduction layer is lower than the permeability of the liquid guide layer, so that the heat conduction layer has a relatively good liquid locking function for liquid and the liquid is prevented from leaking from the surface of the heat conduction layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an atomizing core, an atomizer and an electronic atomizing device. Background technique [0002] Electronic atomization devices have similar appearance and taste to ordinary cigarettes, but usually do not contain other harmful components such as tar and suspended particles in cigarettes, so electronic atomization devices are generally used as a substitute for cigarettes. In the existing electronic atomization device, the liquid is usually transported to the atomization surface of the porous atomization core for atomization under capillary action, and the atomization core often burns dry due to the high local temperature of the atomization surface during suction. smell and other harmful substances, thereby affecting the user experience. Contents of the invention [0003] A technical problem solved by the invention is how to avoid dry burning of the atomizing core. [0004] An...
