The power supply of the general ultrasonic humidifier is to rectify the mains power of 220 into DC 24V after passing through the transformer, of course, there are other voltages, but they are generally safe voltages and will not be too high. The operating frequency of humidifiers is generally in the megahertz range.

The circuit generates an oscillating impulse voltage above 20 kilohertz, which drives the electro-acoustic conversion piezoelectric ceramic, causing it to generate mechanical vibrations and vibrate the water, atomizing it.

Generally, humidifiers are 220V.

Home is the mains! That's 220V

From the diagram, the position of the red and black plug is the power input. Red and black with 220 will do.

This is the circuit board and power cord of the ultrasonic cleaner.

Power ratio = square ratio of voltage. Power plugged into a 380V AC power supply = 100W * (380 * 380) (220 * 220) = 298WIt is estimated that it will burn in a few seconds after plugging it in.

True line; I can repair my mobile phone by myself, the solder joints on the mobile phone are very small, I see that the ferrochrome head used to repair the mobile phone is very small, and the solder wire is used as solder, how much power w is to go to the mobile phone repair shop to know, you can buy it in the hardware store.

The power of the commonly used solderless soldering table soldering iron is 60W, 80W and 100W!

This depends on what kind of ultrasonic cleaner you use, if it is a small ultrasonic cleaner from one to 30 liters, you can connect it directly to the power supply, if it is a large industrial machine, you need to check the specific manual. Of course, except for the all-in-one machine, the all-in-one machine can be directly connected to the power supply, if you don't check the interface Peugeot. In conclusion, it is a very simple wiring process.

You can just pick it up, buy the equipment and find me.

Hello, to fix the ultrasonic oscillator, first of all, weld the screws on the bottom plate (buy the ultrasonic oscillator with matching screws for you), ensure that the surrounding area of the bottom plate welding screws is waterless and clean, coat the oscillator with a special glue sticky ultrasonic oscillator, twist it tightly, and wait for the glue to dry on it!

1. Preparation tools: argon arc welding, No. 10 hexagon wrench, chromium iron tin wire, square high temperature.

wire, 2* cable appropriate amount, vibrator glue, (wire strippers, casing, cable ties, sandblasting machine, pipe fittings, etc.).

2. Welding screws: calculate the oscillator arrangement position, weld the screws in the cleaned position, and then clean the screws around them, be sure to make them flat, so as not to affect the installation of the oscillator.

3. Glue configuration: will.

A glue squeeze around the screws and then place.

B. Glue squeeze a circle in A-glue.

aside, then quickly stir with a small iron bar.

AB glue so that it is well mixed evenly.

Fourth, install the vibrating head:

Twist the transducer a little hard to squeeze out the air and excess glue between the contact surface between the bottom and the bottom of the cylinder, so that the oscillator is more tightly combined with the stainless steel as a whole.

5. Curing and condensation: curing in a place with relatively high room temperature, it can be wired in 4-8 hours, 24 hours.

Later, it can be powered on to test the machine.

For ultrasonic waves and infrasound waves, they are both sound waves, which cannot propagate in a vacuum, and when propagating in the air, if the distance is very far, its energy loss is a lot, which affects the sound transmission effect;

For visible light, it is an electromagnetic wave, which is easily disturbed when transmitting information, and the loss is serious; Mobile phones that work normally in life use electromagnetic waves or microwaves to transmit information

So choose A

How can I use my phone to send messages more conveniently? Answer: Then you write all the mobile phone numbers that you often use in your home on a blank piece of paper with a ballpoint pen or marker, and then paste this piece of paper on the front of your house door with adhesive tape or pushpins.

You can also write all the mobile phone numbers that you often use in your home directly on the front of your house door with chalk or loess blocks, and after you write it, make sure that when there is no one in your house and the door is locked, when others pass by your door, others can see the mobile phone number you write. This makes it more convenient to use your phone to send information.

The working voltage of the humidifier is about 36V, the fan voltage is 12V, and the output voltage of the mobile phone charger is too low and the capacity is too small.
