[0002] At present, the technology of non-invasive beauty treatment with focused ultrasound has been widely used. The principle is that a focused ultrasound transducer installed inside the handle emits focused ultrasound. After the ultrasound is focused on the subcutaneous tissue or fat tissue, a "high temperature point" with a small volume and a temperature of 50-75°C is formed, thereby causing the local subcutaneous tissue to shrink under the action of high temperature, which helps to improve the firmness of the skin. For related equipment, please refer to the Chinese patent publication with publication number CN219128072U and the name "Ultrasonic Beauty Instrument Handle Assembly and Ultrasonic Beauty Instrument", which records: "An ultrasonic beauty instrument handle assembly, including: A base, a transducer, a connecting mechanism and a driving mechanism, wherein the transducer is arranged in the base, the connecting mechanism is respectively connected to the transducer and the driving mechanism, and the driving mechanism is used to drive the planar movement of the transducer. The utility model realizes true planar focusing, releases energy and maintains a uniform focal length, so that it can perform accurate and efficient treatments, and ensures safety, adapts to the treatment of different parts of the human body, and can form treatment areas of different shapes on the skin. "Although such mechanisms can radiate ultrasonic waves to the skin, when ultrasonic waves act on the human body, they will produce instantaneous temperature rise, causing discomfort to the human skin, so the user experience is poor.
