Abstract

An atomization assembly and an electronic cigarette are provided. The atomization assembly configured to combine with a battery assembly to form the electronic cigarette comprises an atomizer and an oil container detachably connected to one end of the atomizer. A smoke outlet configured to discharge atomized smoke is defined on the other end of the atomizer, away from the oil container. The atomizer comprises an atomization sleeve; a heating wire assembly provided in the atomization sleeve, and an oil delivery mechanism inserted in the oil container and configured to deliver the oil to be atomized to the heating wire assembly. The heating wire assembly comprises a liquid delivery element extended along an axial direction of the atomizer, and a heating wire twined around the liquid delivery element.
