Principle of micro nebulizer

The high-frequency current generated by the ultrasonic generator passes through the ultrasonic transducer to convert the high-frequency current into sound waves of the same frequency. The ultrasonic wave generated by the transducer passes through the sound permeable film at the bottom of the atomizing cup, so that the ultrasonic wave acts directly on the liquid in the atomizing cup. When the ultrasonic wave is transmitted from the bottom of the cup to the surface of the liquid medicine, it forms a tension wave on the surface of the liquid medicine under the action of the ultrasonic wave perpendicular to the interface. With the increase of the energy of the surface tension wave, when the energy of the surface tension wave reaches a certain value, the peak of the tension wave on the surface of the liquid medicine increases at the same time, and the liquid mist particles at the peak fly out. Due to the uniform size and small momentum of the fog particles produced by ultrasonic wave, they are easy to walk with the air. After the ultrasonic atomizer splits the liquid medicine into particles, the air flow generated by the air supply device generates the medicine mist, and the medicine mist is delivered to the patients through the fog supply pipe.
