Abstract: An atomizer and an electronic cigarette are provided. The atomizer comprises an outer housing, and an e-liquid storage chamber and an atomization assembly are disposed in the outer housing. The atomization assembly comprises a porous element and a heating element. The porous element comprises an e-liquid absorbing surface. A bubble guiding element opposite to the e-liquid absorbing surface is further provided in the outer housing, and comprises a bubble guiding surface opposite to the e-liquid absorbing surface. At least a portion of the bubble guiding surface is obliquely configured in a direction facing away from the e-liquid absorbing surface, such that bubbles emerging from the e-liquid absorbing surface of the porous element are guided toward the direction facing away from the e-liquid absorbing surface.

Abstract: An electronic cigarette atomizer, comprising a 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 by means of laser tapping, mechanical perforating, and other approaches.
