Home nebulizers can be used for respiratory diseases such as asthma, bronchitis, pneumonia, etc.
1) Working principle of ultrasonic atomizer: The ultrasonic atomizer generates high-frequency current from the ultrasonic generator. After passing through the ultrasonic transducer, it converts the high-frequency current into sound waves of the same frequency, and then passes through the coupling in the atomization cylinder. The action, and the ultrasonic film at the bottom of the atomization cup, make the ultrasonic waves directly act on the liquid in the atomization cup. When ultrasonic waves are transmitted from the bottom of the cup to the surface of the liquid medicine, the liquid-gas interface, that is, the interface between the liquid medicine surface and the air, is acted upon by ultrasonic waves perpendicular to the interface (i.e., energy action), causing the surface of the liquid medicine to form tension. As the energy of the surface tension wave increases, 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 also increases at the same time, causing the liquid mist particles at the peak to fly out. Then the air flow generated by the air supply device generates chemical mist.
Suitable for: nose, throat and upper respiratory tract
2) Working principle of compression atomizer:
Compressed air atomizer is also called jet or jet atomizer, which is based on Venturi
(Venturi) injection principle uses compressed air to form a high-speed airflow through a small nozzle, and generates negative pressure to drive liquid or other fluids to be sprayed onto the barrier. Under high-speed impact, they splash around and turn the droplets into mist particles from the outlet. Tracheal ejection.
Suitable for: nose, upper and lower respiratory tract and lungs
3) Working principle of mesh atomizer: Mesh atomizer, also called vibrating mesh atomizer. It uses a sieve membrane, that is, the violent vibration of the atomizer, to squeeze and release the medicinal liquid through fixed tiny sieves. Atomizer sheets are usually composed of piezoelectric devices, spray sheets and other fixed components. A high-frequency oscillation signal is generated by the microcontroller and sent to the piezoelectric device, causing bending deformation due to the piezoelectric effect. This deformation drives the axial vibration of the spray blade fixed on the piezoelectric sheet. The spray blade continuously squeezes the liquid. The liquid passes through hundreds of micropores in the center of the spray blade and is ejected from the surface of the spray blade to form mist droplets. For patient to inhale.
Applicable to: upper and lower respiratory tract and lungs
