Atomizing head, atomizer and electronic cigarette having same

Abstract

An exemplary atomizer includes an atomizing tube and an atomizing head. The atomizing tube defines a space configured for receiving a liquid supply filled with tobacco liquid. The atomizing head includes a holder, an air inlet, an air outlet, a piercing element, a buffer chamber, an atomizing cavity, and an atomizing component. The piercing element is configured for piercing the liquid supply. The piercing element defines a liquid inlet. The buffer chamber is configured for storing the tobacco liquid flowed from the liquid supply via the liquid inlet after the liquid supply is pierced. The liquid inlet is in communication with the buffer chamber and the liquid supply. Both of the air inlet and the air outlet communicates with the atomizing cavity. The atomizing component is configured for absorbing the tobacco liquid in the buffer chamber and heating the tobacco liquid to vaporize.
