The present invention provides a 3D atomizing heating component comprising a plate body having upper and lower surfaces, the plate body providing a plurality of 3D heating units for guiding, heating and atomizing the e-liquid. The 3D heating units have a through hole in the plate body and guide channels distributed regularly at the periphery of the through hole, which runs through the upper and lower surfaces of the plate body. The guide channels are recessed from the surface of the plate body and communicate with the through hole. The guide channels of the adjacent 3D heating units are connected with each other on the surface of the plate body, and the plurality of 3D heating units form a regular pattern on the surface of the plate body. The components provided improve the taste and user experience. Manufacturing is easy, facilitating the mass and mechanical production.
