The disclosure relates to an atomization device for atomizing liquid into steam to be inhaled by users via heating through micro-pores, in particular to a heating atomization core and assembly having a multi-core porous liquid-conducting material.
Most existing heating assemblies based on micro-porous electrical heating wires in the field adopt a single-piece heating mode and have a cylindrical or planar heating region. When the heating area is large, the temperature of the middle region of the heating surface is higher than that of the peripheral region of the heating surface due to thermal radiation. So, when the existing heating assemblies are used to atomize liquid, liquid in the peripheral region will not be sufficiently atomized due to non-uniform temperature distribution, or a smell of burning will be generated in the middle region due to an excessively high temperature.
The disclosure provides a novel technical solution to solve the technical problems of the prior art.
The objective of the disclosure is to disclose a heating atomization core and assembly having a multi-core porous liquid-conducting material.

Preferably, the electrical heating track element of the heating atomization core having a multi-core porous liquid-conducting material is formed by an electrically conductive heating plate through stamping, cutting, or etching, or is formed by an electrically conductive metal paste printed on the porous liquid-conducting material body.
Based on the heating atomization core having a multi-core porous liquid-conducting material, the disclosure further provides another technical solution: a heating atomization assembly having a multi-core porous liquid-conducting material comprises the heating atomization core.

Preferably, the base of the heating atomization assembly having a multi-core porous liquid-conducting material is provided with air inlets which are communicated with a space where the electrical heating track element is located, and an outlet channel is formed in the tank and is communicated with the space where the electrical heating track element is located.
Preferably, the porous liquid-conducting material body of the heating atomization assembly having a multi-core porous liquid-conducting material is provided with an intermediate through hole, the intermediate through hole is formed in the center of the porous liquid-conducting material body and is perpendicular to a heating surface attached with a heating plate, and a lower end of the outlet channel penetrates through the intermediate through hole.
Preferably, the base of the heating atomization assembly having a multi-core porous liquid-conducting material is provided with electrode mounting holes, and the first electrode and the second electrode are mounted in the electrode mounting holes.
