Description

Technical Field

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

[0002] Ultrasonic 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 ultrasonic nebulizer is an important therapeutic device for treating respiratory system diseases such as bronchitis and asthma.

[0003] The core component of the ultrasonic nebulizer is its internal atomization assembly, which is equipped with an ultrasonic atomizer. When an electrical signal acts on the ultrasonic atomizer (usually made of ceramic material), the atomizer will generate high-frequency vibrations, which in turn convert electrical energy into ultrasonic energy. The ultrasonic energy acts on liquid water molecules, and the directional pressure and vibration effects of the ultrasonic waves break up the structure of liquid water molecules, forming tiny physical particles, namely water mist. The high-frequency resonance of the ceramic atomizer continuously produces water mist. This naturally flowing water mist is then blown from the bottom to the outlet through the fan or airflow system inside the atomizer.

[0004] The atomizer is one of the core components of an ultrasonic nebulizer, and its working condition directly affects the atomization effect and the performance of the device. Over time, scale, dirt, or other impurities may accumulate on the surface of the atomizer, which will affect the atomization efficiency and quality and may even cause equipment failure. Therefore, the atomizer needs to be cleaned. However, the atomizer module in existing atomizers adopts two structures: an integral structure or a bulk structure. The integral structure refers to the various components of the atomizer module being organized into a whole and fixed, and then the atomizer module is installed in the atomizer. This atomizer module is relatively difficult to disassemble and requires professional tools; the bulk structure refers to the various components of the atomizer module being installed one by one into the atomizer. Although this structure reduces the difficulty of disassembling the atomizer, it makes it difficult for people who are not familiar with the internal structure of the atomizer to install and reinstall it. At the same time, this method also seriously affects the production efficiency of the ultrasonic atomizer. Due to the small size of each component and the limited installation space of the ultrasonic atomizer body, it is easy to cause damage to the components during the installation process, affecting the product defect rate.
