Cotton swab*1
Driver module
The drive module of the humidifier has strong versatility, large mist output, stable performance, continuous spray mode and intermittent spray mode, and automatic timing shutdown function to meet different use needs and save power. 5V USB power supply mode, you can use the Android system mobile phone charging cable to plug into a mobile phone charger, computer USB, power bank, etc. for power supply.
Parameter:
Working voltage: DC5V (Default MicroUSB port input, can also be connected externally by welding wire)
Working current: 300mA
Rated power: 2W
Frequency: 108KHz (fixed frequency microcontroller)
Board size: 35*20*17mm (length*width*height)
Mode Description:
1. Continuous spray mode
After powering on, press the switch once, the LED light will always be on, and it will enter the continuous spray mode and keep spraying. After spraying for 4 hours, it will automatically shut down for protection.
2. Intermittent spray mode
After powering on, press the switch twice or press the switch again in the continuous spray mode to enter the intermittent spray mode, spray for 10 seconds, stop spraying for 5 seconds, and cycle in turn. After spraying for 12 hours, it will automatically shut down for protection.
3. Shut down
After powering on, press the switch three times or press the switch again in intermittent spray mode to shut down and stop spraying.
Panel description:
Invalid switch:
If there is no need to control the spray through the switch, the switch function will be disabled. If you need the function of spraying when power is turned on, you can solder these two pads together. Without the switch function, the scheduled spray function will also be invalid and continue to spray without the scheduled shutdown function.
External wire:
Do not use the Micro to USB power cable for power supply, and need an external power cable for direct power supply. The two + and – pads can be welded to the positive and negative polar symbol pad welding wires to power the circuit board directly.
Atomizer tablet
After the humidifier has been in operation for several months, the amount of mineral mist produced on the surface of the atomizing sheet will decrease, and there will be no mist, the mist spray will not be high, or a hard object will pierce the atomizing steel sheet, and the white piezoelectric ceramic sheet will be degummed and cracked. If there are white stains on the surface of the atomizer chip, replace it with a new atomizer chip, and the fog volume will return to normal. This type of atomizer has plug-and-play terminals, wires, and silicone rings. The single atomizer is directly connected to the power supply without fogging. It needs to be equipped with a driver circuit board to produce fog. It is suitable for USB humidifiers with 5V DC. Microporous atomizers are used in various USB mini humidifiers, cosmetic sprayers, medical micro atomizers, aromatherapy essential oil atomizers, toys, and other fields.
Product features:
This microporous atomizer has passed a complete quality monitoring system inspection and has passed a series of electrical performance inspections such as appearance inspection, flatness screening, capacitance, and frequency inspection for piezoelectric wafers throughout the entire process, and selected high-quality metal diaphragms. The aperture, number of holes, and thickness of the tablets are reasonably matched and glued together to ensure that the pass rate of each batch of microporous atomizing tablets reaches more than 99%. It has the following characteristics:
①Ultra-fine spray particles, large atomization volume, high atomization height, and will not wet the desktop;
② Low driving voltage, low power, low impedance, stable waveform, and high conversion efficiency;
③Low dielectric loss, low heat generation, corrosion resistance, acid and alkali resistance, and long service life;
④Ring-shaped, middle spray, 5um ultra-fine spray aperture, 740 ultra-dense spray holes;
⑤ Anti-oxidation silver layer protective coating process, with a service life of more than 3000 hours;
⑥ Contains PH2.0 terminal blocks. If there is a female socket on the circuit board, it can be used directly without welding.
Product parameters:
Working voltage: DC 5V
Frequency: 110KHz
Working current: 300mA
Number of holes: 740
Rated power: 2W
Aperture: 5um
Rubber ring outer diameter: 20mm
Cord length: 8cm
Steel sheet diameter: 16mm

Precautions:
1. The atomizer must match the model before it can be used. Please confirm whether the parameters of your original atomizer are consistent with the parameters of this atomizer so as not to buy the wrong one and be unable to use it.
2. To measure the atomizer, the silicone ring needs to be removed to confirm whether the steel sheet diameter of the atomizer is 16mm.
3. The atomizer sheet is only a humidifier accessory and cannot be used alone. It must be used with the USB 5V mini humidifier driver circuit board.
4. The atomizer is fragile, so be careful when unpacking and placing it.
5. If the atomizer wire in your humidifier is directly welded to the circuit board, you can use a soldering iron to solder the original red wire (positive pole) and black wire (negative pole) respectively. If you don’t have a soldering iron, you can directly connect the red wire (positive pole) and black wire (negative pole) with tape.
6. After using it for a period of time, there are minerals on the surface. Do not try to clean or scrape the atomizing sheet with hard things, which will completely destroy the atomizing sheet. Use white vinegar to gently wipe the two sides of the atomizing sheet to wipe off the white crystals or replace them.
Cotton swab
Features:
① USB humidifier absorbent cotton swabs can also be used as a perfume evaporator stick.
②No glue, strong water absorption, sufficient elasticity, no yellowing, no burrs.
③ The cotton swab specifications are 8mm in diameter and 130mm in length.
④ The cotton swab is made of glue-free acetate fiber.
Precautions:
1. Each humidifier cotton swab has different specifications. Before taking the photo, measure whether the diameter and length of your original cotton swab match ours; otherwise, it may not be usable. The specifications of our cotton swab are 8mm in diameter and 130mm in length.
2. The diameter of the cotton swab is close to that of the cotton swab casing and can also be used. If the length is too long, you can use a utility knife to cut it to a suitable length. Install the cut end downward to absorb water to ensure a stable mist output. The uncut end is in contact with the atomizer sheet.
