Electronic atomization device, and atomizer and heating assembly thereof

Abstract

The invention relates to an electronic atomization device, and an atomizer and a heating assembly thereof. The heating assembly comprises a porous body and a heating body, wherein the porous body comprises a first surface and a second surface which are oppositely arranged; the first surface is an atomization surface for mounting the heating body; the second surface is recessed inwards to form a liquid guide hole for containing a liquid guide element; the liquid guide hole has a bottom surface; the bottom surface of the liquid guide hole is a core atomization area in a projection area of the atomization surface; the core atomization area is a centralized distribution area of the heating body; and during normal working, after the heating body performs heating for a preset time, a first average temperature of the core atomization area is higher than a second average temperature of the whole atomization surface. When the heating assembly performs heating, the temperature of the core atomization area is relatively high and the volatilization speed of a liquid medium is relatively high, so that the liquid medium outside the core atomization area can flow to the core atomization area andis gathered to the core atomization area, and liquid leakage can be avoided.

Description

technical field [0001] The invention relates to the field of articles for smokers, and more specifically, relates to an electronic atomization device, an atomizer and a heating component thereof. Background technique [0002] Electronic cigarettes are also known as virtual cigarettes and electronic atomization devices. As an alternative to cigarettes, electronic cigarettes are mostly used for smoking cessation. E-cigarettes have a similar appearance and taste to cigarettes, but generally do not contain other harmful components such as tar and suspended particles in cigarettes. [0003] The electronic cigarette is mainly composed of an atomizer and a power supply device. The atomizer generally includes a heating element that heats and atomizes the smoke liquid after being energized. The heating element generally includes a porous structure for liquid conduction and a heating element that cooperates with the porous structure. The oil supply area of ​​the existing heating com...

AI Technical Summary

Problems solved by technology

The oil supply area of ​​the existing heating components is usually larger than the atomization area. In the case of unobstructed ventilation, liquid leakage is prone to occur, that is, leakage of smoke liquid, resulting in waste of smoke liquid, poor user experience, and even smoke liquid pollution. Electronic components, resulting in the failure of electronic components
