There are many imitations of ultrasonic on the market. Just install an electric motor and it's ultrasonic. I really have no tears to shed when encountering people who don't understand.

        "Ultrasonic cleaning process technology" refers to the use of the cavitation effect of ultrasonic waves to impact and peel off dirt on the surface of objects to achieve the cleaning purpose. It features high cleaning cleanliness and fast cleaning speed. Especially for blind holes and various geometric objects, it has a unique cleaning effect that other cleaning methods cannot achieve.

        The working principle of an ultrasonic cleaner: The cleaner acts on water molecules at a vibration frequency of 42,000 times per second. The cavitation effect of water impacts the surface of the object, thereby meeting the cleaning requirements. Ultrasonic cleaners also produce noise when in operation. You can reduce the noise by filling the cleaning liquid as much as possible and covering the machine lid.

      Ultrasonic cleaning has two advantages: one is that it cleans thoroughly, and the other is that it can kill bacteria. Effectively remove protein deposits, microorganisms, dust in the air and bacteria adhering to the lenses. It is cleaner and more hygienic than hand washing, more comfortable to wear and can extend the service life of the lenses.
