Description

Atomizer assembly and atomizer Technical Field The embodiment of the application relates to the field of medical instruments, in particular to an atomizer assembly and an atomizer. Background In the field of medical devices, nebulizers are a common medical device for converting liquid drugs into aerosol form for inhalation by patients. Generally, an atomizer has a main body device having a compressor for generating compressed air, and an atomizer assembly including a medicine cup or the like for converting medicine liquid in the medicine cup into aerosol by introducing the compressed air. The operation and the use of the atomizer are simple and convenient, but the patient is required to keep a sitting posture or a backward leaning posture during atomization treatment, the existing liquid medicine cup is generally vertically arranged, and the current liquid medicine cup is usually only supported to incline within 45 degrees at most.
