Abstract: One atomizer for an artificial cigarette includes an atomizing assembly and an adjustment assembly thereon. The atomizing assembly includes an accommodation cavity and the adjustment assembly includes a substrate and an adjustment member rotatably disposed on the substrate. A liquid inlet port is defined in the substrate, the port communicating with the accommodation cavity. The adjustment member adjusts a size of the liquid inlet port exposed during rotation of the adjustment member. A second atomizer includes an atomizing assembly and an air inlet port, the atomizing assembly includes an atomizing cavity and an air passage. The air passage has one end communicating with a top of the atomizing cavity and another end communicating with the air inlet port. An aerosol generating device including either one of the above atomizers is also provided.

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.
