Document Type and Number:
WIPO Patent Application WO/2021/051386
Kind Code:
A1
Abstract:
An ultrasonic cleaning device, and a cleaning method and an application thereof. The ultrasonic cleaning device comprises a single-channel signal transmitter (10), a single-channel transducer (20), a gradient spiral sound structure member (30) disposed on a transmitting end of the single-channel transducer (20) and configured to generate a vortex sound field, and a water tank (40) configured to contain a cleaning liquid medium. Both the single-channel signal transmitter (10) and the gradient spiral sound structure member (30) are disposed in the water tank (40) and located below an object to be cleaned. The vortex sound field generated by the device has a shear force perpendicular to a transmitting direction, and therefore, cavitation damage caused by cavitation can be avoided.
