High-frequency oscillation, micrometer aperture, large atomization amount, fine mist particles, high spray rate, spray variety, timed shutdown. Two spray modes: press the switch for the first time is continuous spray mode: LED light is always on, always spray, spray 4 hours after the automatic shutdown protection. Press the switch for the second time is indirect spray mode: LED flashes, spray 10 seconds, stop spraying for 5 seconds, and so on, spray 12 hours after the automatic shutdown protection. Press the switch for the third time to turn off the machine. The white piezoelectric ceramic ring surface is the front spray surface, which is installed upward, All steel sheet surface is the suction surface on the back, installed downwards. The red wire is positive and the black wire is negative. Spray Principle: Piezoelectric ceramics drive metal plate high-frequency oscillation, ultrasonic liquid atomization. Micrometer-fine water molecules atomize water throughmicropores and disperse it into the air. Application: DIY spray, plant humidification, landscaping atomization. The atomizing piece needs to be used together with the circuit board with the same frequency to achieve the perfectspray amount.
