AI Technical Summary

Technical Problem

Existing ultrasonic beauty devices cannot automatically and continuously adjust output parameters according to the real-time needs of different areas of the face, resulting in low repeatability and consistency of use, and making it difficult to achieve deep output by intelligent zoning of different areas.

Method used

By adopting a sliding fit structure between the transmission sleeve and the eccentric rod, and by setting circumferential continuous guide patterns on the inner circumference of the transmission sleeve and the outer circumference of the eccentric rod, the focusing depth of the ultrasonic transducer can be continuously adjusted. Combined with a closed-loop calibration component and a photoelectric sensor for real-time displacement feedback, the focusing depth of ultrasonic energy can be precisely controlled.

Benefits of technology

It enables precise focusing of ultrasonic energy onto different skin layers, improving the targeting and effectiveness of care, and enhancing the repeatability and consistency of care.

Abstract

The application is suitable for the technical field of ultrasonic beauty, and provides a depth adjusting assembly, an ultrasonic beauty instrument and a control method thereof. The depth adjusting assembly comprises: a transmission sleeve, which is provided with a first guide pattern on an inner periphery and has a tail end for connecting an ultrasonic transducer; and an eccentric rod, which is provided with a second guide pattern on an outer periphery, the eccentric rod passes through the transmission sleeve, so that the first guide pattern and the second guide pattern are in sliding fit to adjust the focusing depth of the ultrasonic transducer; wherein the first guide pattern and the second guide pattern are both continuous patterns arranged in a circumferential direction. This structure can realize stepless and smooth depth adjustment, accurately focus ultrasonic energy on different target layers, and improve the pertinence and effect of nursing.
