Product name： Ultrasonic diffuser PCBA
Description：
USB 5V power supply (upgradable built-in lithium battery), equipped with 103-120KHZ microporous atomizer, can atomize pure essential oils, and will not destroy the components of plant essential oils, atomized particles are as small as 1-3μm, and can be effectively dissolved in the air , the diffuser effect is remarkable.
Parameter：
1. During the discharge process of the battery voltage from 4.2V to 3.2V, the output power can be precisely controlled to ensure the consistency of the fog volume, and the power accuracy is 0.3%;
2. The fluctuation range of the working current in different gears is smaller, the operation is more stable, and the current accuracy is 0.1%;
3. Under the condition of ensuring the core performance of the atomizer remains unchanged, the matching performance of PCBA and atomizer is higher;
4. Lower standby power consumption of 20µA~30µA;
5. Full gear frequency tracking, faster frequency tracking, more accurate frequency tracking, higher frequency tracking stability, no need for production process debugging.
