Description

Skin care device having a replaceable cartridge The present invention relates to a skin beauty device, wherein a cartridge containing a skin beauty preparation is interchangeably mounted on the main body of the skin beauty device, and the skin beauty preparation contained in the mounted cartridge is automatically dispensed by an actuator of the main body, thereby improving user convenience and facilitating maintenance. For effective skin care, much effort is being made to penetrate the beneficial ingredients of cosmetic products as deep into the skin as possible. This is because cell membranes are equipped with a phospholipid matrix that prevents substances from the external environment from indiscriminately penetrating into the cell, making it difficult for cosmetic ingredients to be effectively absorbed through the skin surface. To overcome this limitation, many types of cosmetic devices are being introduced. For example, a skin beauty device utilizing the electroporation effect has been introduced. Electroporation is a technique that temporarily creates pores in the cell membrane by pulses of high-voltage direct current. Therefore, by applying the electroporation effect to a skin beauty device, it is possible to facilitate the penetration of active ingredients of skin beauty products deeper through the cell membrane. In the use of skin care devices, users have traditionally applied a skin care agent to the skin before holding and using the device; however, user convenience has not been sufficiently considered, as users have had to wash their hands after applying the agent. Therefore, it can be suggested as a desirable solution to enable the immediate use of the skin care device without the need to apply a skin care agent separately. The following drawings attached to this specification illustrate preferred embodiments of the present invention and serve to further enhance understanding of the technical concept of the present invention together with the detailed description of the invention provided below; therefore, the present invention should not be interpreted as being limited only to the matters described in such drawings. FIG. 1 is a perspective view of a skin beauty device according to one embodiment of the present invention. FIG. 2 is a perspective view illustrating a structure in which a cartridge assembly is mounted on the skin beauty device of FIG. 1. FIG. 3 is an incisional cross-sectional view of the skin beauty device of FIG. 1. FIG. 4 is a cross-sectional view illustrating the combined structure of a formulation cartridge and a dispensing mechanism. FIG. 5 is a drawing illustrating a structure in which a Type 1 cartridge is mounted on a cartridge frame. FIG. 6 is a drawing showing the state in which a Type 1 cartridge is separated from a cartridge frame.
