Description

Technical Field

[0001] The utility model relates to the technical field of atomizers, in particular to an atomizer which is convenient for liquid-gas mixing. Background Art

[0002] A nebulizer is a device that atomizes the test solution. Its performance has a significant impact on the precision of the measurement and chemical interference. Therefore, the nebulizer is required to have stable spray, small and uniform droplets, and high atomization efficiency. There are many types of nebulizers according to different uses, among which the main component is the liquid-gas mixing part.

[0003] During the atomization process of the nebulizer, a high relative speed must be generated between the liquid and the air so that the liquid is under the optimal friction condition. The whole process is affected by the size of the liquid properties and the gas flow properties. In the prior art, common atomizers generally use compressed air to form a high-speed airflow through a small tube orifice. The negative pressure generated drives the liquid or other fluids to be sprayed onto the obstruction, and splashes around under high-speed impact to turn the droplets into mist particles. As a result, when the liquid is more viscous due to the mixed liquid, it is more difficult to flow and it is not easy to form small droplets, which affects the liquid-gas mixing degree of the nebulizer and causes the atomization to fail to reach the ideal level.
