Abstract: An atomizer being combined with a power supply to form an electronic cigarette is disclosed. The atomizer comprises: a housing with a first end and a second end; a mouthpiece, connected to the first end of the housing, wherein the second end is connected to the power supply; a reservoir, formed in the housing and configured to contain tobacco liquid; and an atomizing element, configured to atomize the tobacco liquid to form aerosol; wherein an injecting hole and a vent hole are formed on the first end of the housing, the injecting hole and the vent hole are in communication with the reservoir, the atomizer further comprises a cover formed on the first end of the housing, and the cover is configured for exposing or covering the injecting hole and the vent hole. It is more conveniently to inject tobacco liquid for users.

Abstract: An exemplary atomizer includes a main body, a liquid supply, a piercing element, and an atomizing assembly. The liquid supply is configured for storing tobacco liquid. The liquid supply is received in the main body. The liquid supply includes an end wall having a fixing part, a sealing part, and a recessed part. The recessed part connects the fixing part and the sealing part. The piercing element is spatially corresponding to the recessed part. The piercing element is configured for pricking the recessed part in response to an external force, so that the tobacco liquid in the liquid supply flows out, and the atomizing assembly absorbs the tobacco liquid flowed out for vaporization.
