will need to first understand the ultrasonic mist mechanism for quality shell are the main parts, circuit boards, epoxy resin and wafer. Shell directly affects the quality of ultrasonic mist heat and corrosion mechanism, the design of the circuit board will affect the life of the atomizer and atomization quantity, the size of the epoxy resin will affect the sealing effect. Which can be compared to the ultrasonic mist mechanism for quality differences.
