1results about How to "Guaranteed Utilization Efficiency" patented technology

The electronic cigarette atomizing core and the electronic cigarette provided by the embodiments of the present application comprise a porous body and a heating body, the porous body comprises a liquid absorbing end and an atomizing end, the atomizing end is provided with a protrusion, the protrusion has an end face away from the porous body and a side face located at the outer periphery of the protrusion, the heating body is arranged on the end face, and the distance between at least part of the heating body and the edge of the end face is less than a predetermined value, so that at least part of the end face and at least part of the side face form atomizing surfaces. In this way, when the atomizing surfaces formed by the protrusion are fully utilized, the utilization efficiency of the heat energy of the heating body can be ensured on the basis of improving the heating rate of the heating body.
