Anti-aging, corrosion-resistant and durable. Precautions: 1. Please do not turn the atomizer upside down after connecting the power, it will damage the atomizer. 2. Please ensure that the running time does not exceed 10 hours per day. 3. When the atomizer is running, please do not touch the atomizing sheet. 4. To ensure the water quality, please use clean tap water. (The deterioration of water quality will affect the service life) 5. Please cut off the power before moving or repairing. 6. The atomizing sheet is a consumable item, and its service life is about 5000 hours. If you find that the amount of mist produced by the atomizer is significantly reduced, please use a cotton swab to clean the atomizing sheet (without any detergent) to keep the atomizing sheet clean. If you find that the amount of atomization is still very small after cleaning, please replace a atomizing piece. 20mm (transducer, oscillator) The net diameter of the atomizing sheet steel sheet is 20mm, and the outer diameter of the rubber ring with rubber ring is 25mm Size: 20x1.2mm Resonant frequency: 1.70MHz Resonant Impedance: Coupling factor: > 52 % Static capacitance: 1800pF Voltage: 5V Atomization volume: 16mm (humidifier transducer 108KHz) 1. The net diameter of the atomizing sheet steel sheet is 16mm, the outer diameter of the rubber ring with a rubber ring is 20mm, and the wire length is 8cm-10cm. 2. The product voltage is DC5V, the power is 2W, and the frequency is 108KHz. 3. Ultra-fine spray particles, large amount of atomization, high atomization height, and no wet desktop; 4. Low driving voltage, low power, low impedance, stable waveform and high conversion efficiency; 5. Low dielectric lo, low calorific value, corrosion resistance, acid and alkali resistance, and long service life; 6, circular, intermediate spray, 5um ultra-fine spray aperture. 7. Anti-oxidation silver layer protects the coating proce, with a life span of more than 3000 hour 16mm With TerminalNet diameter of steel sheet: 16mmOuter diameter of rubber ring with rubber ring: 20mmWire length: 65mmProduct voltage: DC 3V-5VPower: 1.5WFrequency: 108KHz 20mm (ultrasonic transducer without rubber ring) The diameter of the atomizing sheet is 20mm, without apron and without wire Note: The diameter marked refers to the size of the rubber ring removed. When measuring, it is important to remove the size of the outer rubber ring. (Regarding the two wires on the atomizer, due to different batches, sometimes they are red and black, and sometimes they are yellow and blue. The others are the same and do not affect the use) Package Included 1 Pcs Humidifier Acceorie
