Abstract

The present invention provides an atomizing assembly and an electronic cigarette. The atomizing assembly includes a base and an atomizing core. A liquid storing cavity is disposed inside the base to store liquid tobacco. The atomizing core includes a body and a heater. An atomizing channel is opened and disposed to penetrate through the body. The heater is disposed on an inner wall of the atomizing channel. The body is made from porous materials. An outer sidewall of the body includes at least an absorbing face. A liquid conducting hole or a plurality of liquid conducting holes is opened and disposed on the absorbing face and extends into a wall of the body from the absorbing face. A contact area between the liquid tobacco and the absorbing face is large to facilitate control of an amount of conducted liquid tobacco.
