Don’t leave ultrasonic atomizer setting water in condition under -10 C°.
Hello.
Recently, we had inquiry from ultrasonic atomizer JM series user, “device stop atomizing mist”. We instruct user to send back us an atomizer, and start inspection, disassembled unit.
..and we found that transducer has a crack in cruciform.
Transducer=Component when it hit to substance or water, it emerges ultrasonic by vibrating. It has installed in all ultrasonic products.
Inspection and reason of malfunction
The user was using at very cold place, that is under 0C°temperature.
We think that temperature is concerning to this device trouble, and we start experiment, put ultrasonic atomizer setting water in the refrigerator for a day.
Next day, we took device from refrigerator and found the transducer was broken in cruciformly.
Seems the water inside the unit get iced and pressuring transducer.
This phenomenon called frost heaving. When water turns to ice, substance volume will heave.
Prevention of transducer malfunction
When you use ultrasonic atomizer, please conform the points below.
・Keep clean the device once in a 3 days.
・Don’t keep device setting water, exposing in cold place.
・Don’t let activate a device without charging water.
・Don’t use a liquid, except our designated solution.
These are major reason, leads device(transducer) trouble.
Let’s use safety, and make your life better sterilizing(use HClO) around you!
