Abstract：Objective To design a scheme that can simplify the water level detection structure of the sinks in the mainstream medical ultrasonic atomizers. Methods A new type of non-contact liquid level detection technique based on capacitive sensing principle was used to detect water level at the outer wall of the atomizer. Results The new liquid level detection technique could accurately judge the water shortage in the flume. It could stop the atomizer from working when the water was lacking and made the atomizer work normally when the water was adequate. Conclusion The new liquid level detection technology is safe and reliable, which is an excellent alternative to traditional water level detection technology. The technology can not only prevent the atomizing piece from being overheated and damaging the atomizer, but also simplify the water level detection structure of the sink, so as to lessen the disinfection blind angles in the sink, reduce the rate of then generation of bacteria and dirts and the rate of superinfection in the hospital.
