Typical working principles of ultrasonic cleaners

An ultrasonic cleaner is a device that uses high-frequency sound waves to clean various items. It's commonly used in industries such as jewelry, electronics, healthcare, and automotive, as well as in households for cleaning delicate objects.

Here's how an ultrasonic cleaner typically works:

Tank: The cleaner consists of a tank filled with a cleaning solution. The size of the tank varies depending on the intended use.

Transducers: The tank contains one or more piezoelectric transducers attached to its bottom or sides. These transducers convert electrical energy into high-frequency sound waves.

Cleaning Solution: The tank is filled with a suitable cleaning solution or solvent, depending on the type of objects being cleaned. The cleaning solution helps remove dirt, grime, oil, and other contaminants from the items.

Cavitation: When the ultrasonic cleaner is turned on, the transducers vibrate at a high frequency (typically between 20 kHz and 40 kHz), creating ultrasonic waves in the cleaning solution. These sound waves create tiny bubbles through a process called cavitation.

Cleaning Action: The bubbles created during cavitation collapse rapidly in a process known as implosion. When the bubbles collapse, they release energy in the form of shock waves. These shock waves generate high-pressure streams of liquid that remove dirt and contaminants from the surfaces of the items being cleaned. This action reaches into small crevices and hard-to-reach areas that are difficult to clean by other means.

Cleaning Process: The items to be cleaned are placed in a basket or holder and submerged into the tank filled with the cleaning solution. The ultrasonic waves generated by the transducers create the cleaning action, effectively removing dirt and contaminants from the items. The cleaning process typically lasts for a few minutes to several minutes, depending on the desired level of cleanliness and the type of items being cleaned.

Rinse and Dry: After the ultrasonic cleaning process, the items are rinsed to remove any remaining cleaning solution. They are then dried thoroughly, either by air drying or using other suitable methods.

It's important to note that not all items are suitable for ultrasonic cleaning. Delicate items, such as certain gemstones, soft plastics, or items with loose parts, may be sensitive to the vibrations and could get damaged. It's essential to refer to the manufacturer's instructions or seek professional advice before using an ultrasonic cleaner on specific items.

Ultrasonic cleaners offer a fast and efficient method for cleaning a wide range of objects, providing thorough cleaning in hard-to-reach areas. They are widely used in various industries and can be a valuable tool for maintaining cleanliness and hygiene.
