Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an atomization component and an atomizer. Background Art

[0002] The nebulizer is an important device used for bronchial disinfection and treatment. It mainly converts liquid medicine into mist particles and sends them into the diseased part of the human body through a catheter. Since the liquid medicine can directly reach the diseased part and is easily absorbed, the nebulizer mainly relies on the atomizer to atomize the liquid medicine. However, the aperture of the atomizer is only between 0.5μm and 5μm, which is very easy to get clogged, causing the nebulizer to fail to work. The atomizer or the entire atomizer module must be replaced during maintenance.

[0003] For example, a handheld nebulizer with application number 2019214690369 and a medical handheld nebulizer with application number 2019206754509 can only be disassembled for maintenance to replace the entire atomizer module. During the replacement process, the base, atomizer sheet and sealing ring of the atomizer module are installed one by one into the atomizer body to form the entire atomizer module, which makes the maintenance process of the atomizer module cumbersome and increases the use cost of the atomizer.
