Description

Atomizer and equipment

Technical Field

Background

Atomizers are important components for atomizing solutions, whose properties have a significant influence on the precision of the measurement, chemical disturbances, etc. Therefore, the atomizer is required to be stable in spray, fine and uniform in mist droplets and high in atomization efficiency. In the medical field, the atomizer can send medicine into deeper focus position, in the electron cigarette field, the atomizer can make tobacco tar become the smog of nanometer and provide good taste and the throat sense of inhaling the person. Therefore, atomizers are widely used in various industries.

The atomizer represented by medical ceramic atomization adopts the principle that liquid molecules are scattered by piezoelectric ceramic high-frequency vibration to form aerosol, so that pharmacological components are not destroyed, and the biological safety of medicines is met. However, the taste is poor due to the presence of alcohol solvents. Although the atomizer represented by the ceramic atomizing core of the electronic cigarette can atomize tobacco tar at high temperature to obtain good taste, the atomizer is not suitable for improving the taste of medicines. The reason is that the alcohol can not be separated, the taste of the alcohol is still full after atomization, in addition, the pharmacological components can be destroyed by high temperature and uneven heating, so that the medicine is invalid, and the basic requirement of the safety of medical equipment is not met.

Therefore, how to solve the above-mentioned problems is a technical problem to be solved by those skilled in the art.
