HIFU THE CARTRIGE FOR HIGH INTENSITY FOCUSED ULTRASONIC SKIN CARE DEVICE

摘要

The present invention relates to a cartridge for a high intensity focused ultrasonic (HIFU) skincare device and a skincare device used by mounting the cartridge thereon. According to the present invention, a PCB having a control unit of the cartridge installed therein is installed in a rear protrusion part outside a cartridge housing such that a connector terminal part of the PCB is electrically connected to a connector installed in a head portion of a body when mounted on the body. Moreover, an ultrasonic transducer transfer mechanism device including a piezoelectric motor is installed in a first chamber inside the cartridge, a housing of an ultrasonic transducer is disposed in a second chamber protruding toward a front surface with a smaller width than that of the first chamber while communicating with the first chamber, and an operative portion, In which an outwardly protruding surface of the second chamber comes into surface-contact with an object. In an operation state, an HIFU transducer irradiates a plurality of ultrasonic waves per one shot while being linearly moved by the piezoelectric motor to form a plurality of ultraviolet-focused areas on the object, thereby providing a skincare effect. In particular, the piezoelectric motor (216) is installed in the cartridge (200).
