Abstract: A porous heating body includes a porous body having a first porous portion, a second porous portion and a third porous portion successively disposed in the porous body along a lengthwise direction of the porous body. A cross-sectional area of the first porous portion and a cross-sectional area of the third porous portion are both larger than a cross-sectional area of the second porous portion along a widthwise direction of the porous body. A heating element extends along the lengthwise direction of the porous body is disposed on the porous body. The heating element includes a heating portion. At least one portion of an extension length of the heating portion is overlapped with an extension length of the second porous portion. The porous body is shaped to enhance conductivity of liquid tobacco in a middle thereof, and storing liquid tobacco for replenishing at two bulge ends thereof.

Abstract: An electronic cigarette atomizer, comprising an electronic cigarette liquid storage chamber for storing electronic cigarette liquid, and an atomization assembly for absorbing and atomizing the electronic cigarette liquid. The atomization assembly comprises a porous body and a heating element. The porous body comprises an electronic cigarette liquid absorption surface in contact with the electronic cigarette liquid and an atomization surface. The heating element is provided on the atomization surface. The electronic cigarette liquid absorption surface is provided with a plurality of blind holes and/or grooves extending along the electronic cigarette liquid absorption surface towards the atomization surface. In the atomization assembly, electronic cigarette liquid atomization is performed on the porous body formed with the blind holes and/or grooves.
