Atomizer and aerosol generating device using same

Abstract

An atomizer includes an atomizing assembly having an accommodation cavity and an air passage, and an adjustment assembly disposed on the atomizing assembly. The adjustment assembly includes a substrate and an adjustment member. The substrate defines a liquid inlet port in communication with the accommodation cavity and an air inlet port in communication with the air passage. The adjustment member is an adjustment ring rotatably sleeved on the substrate. The adjustment ring defines an adjustment window. When the adjustment window is at least partially overlapped with the liquid inlet port/the air inlet port by rotating the adjustment ring, the air inlet port/the liquid inlet port is covered by the adjustment ring, and the overlapped portion between the adjustment window and the liquid inlet port is configured for an injection of aerosol source material into the accommodation cavity.
