1. An electronic cigarette atomizer, comprising an electronic cigarette liquid storage chamber for storing electronic cigarette liquid, and an atomization assembly for absorbing the electronic cigarette liquid from the electronic cigarette liquid storage chamber and atomizing the electronic cigarette liquid, wherein the atomization assembly comprises a porous body for conducting the electronic cigarette liquid, and a heating element for atomizing the electronic cigarette liquid; the porous body comprises an electronic cigarette liquid absorption surface in contact with the electronic cigarette liquid and the porous body further comprises an atomization surface; the heating element is provided on the atomization surface; wherein 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;
wherein the heating element comprises a heat generation unit for generating heat, and an electrode connection unit provided on the heat generation unit; wherein
the electronic cigarette liquid absorption surface includes a first electronic cigarette liquid absorption region opposite to the heat generation unit, and a second electronic cigarette liquid absorption region opposite to the electrode connection unit; and
density of the blind holes in the first electronic cigarette liquid absorption region is greater than density of the blind holes in the second electronic cigarette liquid absorption region; and or, density of the grooves in the first electronic cigarette liquid absorption region is greater than density of the grooves in the second electronic cigarette liquid absorption region.
