If there is a "; "at home "Ultrasonic cleaning machine" It's much better," "Ultrasonic cleaning machine" The shape is very small, each white, yellow or black box, about the size of a cute little bread. It achieves the cleaning purpose through the cavitation of ultrasonic waves. After being powered on, the high-frequency oscillation circuit generates a high-frequency ultrasonic wave source. The ultrasonic waves drive the vibration plate to swing, and the vibration plate in turn drives the water to vibrate, thereby forming many tiny bubbles in the water. When the bubbles burst, they generate shock waves, which directly or indirectly decompose, emulsify or peel off dirt and oil stains, achieving the cleaning purpose without causing damage to the items. ultrasonic cleaner can remove food residues in dentures, dust and sweat stains on spectacle lenses, bacteria hidden in toothbrush bristles, and fine dust that makes watches and jewelry no longer shiny.

      The usage method of the cleaning machine is very simple.

When the blue light is on, it indicates that the power has been connected. "Will" ON” Press the key and the red indicator light will come on, indicating that cleaning is in progress. When a pair of glasses that had already been wiped was placed in, the cleaning machine made a slight "sound" while working. "Magnetic" Sound. The ultrasonic frequency is 42000HZ, and the cleaning speed is relatively fast. Three minutes later, the cleaning process ended automatically and the red light went out. The reporter took out the glasses. It was not easy to tell with the naked eye whether there was a cleaning effect or not, but when looking into the water, it was obvious at a glance: tiny fuzz, fine dust particles, and even clumps of flaky oil stains. It was quite disgusting to look at.

      What about the effect of washing a watch? The reporter put in an ordinary non-waterproof watch. A non-waterproof watch needs to be placed on a rainbow-shaped watch stand, with the metal bracelet immersed in water. After the same three minutes, when the watch is taken out, it can be seen that there are many tiny black dust particles in the water. Wipe the watch band with a paper towel. There are still some dust particles left on the white paper towel.
