Abstract: An atomizer includes a liquid storage assembly, an air adjusting assembly and a liquid adjusting assembly. The air adjusting assembly includes an air adjusting ring and an air adjusting seat. The liquid adjusting assembly includes a liquid adjusting seat, an inner sleeve pipe and a liquid barrier ring. When the air adjusting ring is rotated, an area of the air intaking hole communicated with the air intaking slot is adjusted. When the liquid adjusting seat is rotated, the liquid barrier ring is brought to rotate by the inner sleeve pipe, to cause the first liquid intaking hole and the second liquid intaking hole to be communicated with each other or staggered from each other. An electronic cigarette having the atomizer is also provided.

Abstract: An exemplary atomizer includes a housing, a liquid storage chamber, and an atomization assembly. The atomization assembly includes a main body defining a liquid inlet, a liquid absorbing element arranged in the main body. The liquid storage chamber defines a liquid outlet fitting the liquid inlet in an inner sidewall thereof, and a heating element. A blocking element defining a through hole is provided between an inner sidewall of the liquid storage chamber and the main body. One end of the housing is provided with a movable element. The movable element is capable of rotating relative to the housing to cause rotation of the blocking element, thus allowing the liquid inlet and the liquid outlet to be in communication through the through hole or allowing a sidewall of the blocking element to cut off the communication between the liquid inlet and the liquid outlet.
