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.
