Atomizer and electronic cigarette having same

Abstract

An exemplary atomizer includes a liquid supply and an atomizing component. The liquid supply is configured for storing tobacco liquid. The liquid supply has an open end and a sealing layer for sealing the open end. The atomizing component is detachably coupled to the liquid supply by snap fit. The atomizing component is configured for heating the tobacco liquid to vaporize. The atomizing component includes a piercing element, a buffer chamber, and an atomizing unit. The piercing element is configured for pricking the sealing layer, so that the tobacco liquid in the liquid chamber flows into the buffer chamber, when the atomizing component is engaged with the liquid supply. The buffer chamber is configured for storing tobacco liquid flowed from the liquid chamber. The atomizing unit is configured for absorbing the tobacco liquid from the buffer chamber, and generating aerosol from the tobacco liquid.
