1. A cartridge assembly comprising: a cartridge frame having an open mounting port on its upper surface and an opening with a support rim formed on its lower surface, and a receiving space enclosed by a plurality of walls; and a formulation cartridge inserted into the receiving space through the mounting port and seated on the support rim, having a formulation receiving portion inside, having a sealing member installed on the lower surface accessible through the opening that seals the formulation receiving portion and is movable by external pressure, and having a nozzle protruding out of the cartridge frame. A head portion having a cartridge mounting portion into which the above cartridge assembly is inserted and mounted as a sliding structure, and a massage pad having a formulation dispensing port that exposes the nozzle tip of the inserted and mounted formulation cartridge; A main body part having a dispensing mechanism that is coupled to the head part below the opening of a cartridge frame inserted and mounted in the head part and performs a lifting movement to pressurize and move a sealing member of a formulation cartridge inserted and mounted in the head part; and A locking mechanism that enters the rear of the cartridge frame according to the lifting and lowering movement of the discharge mechanism to prevent the detachment of the cartridge assembly; A skin beauty device including
2. In paragraph 1, The above discharge mechanism includes a pressure block that accesses the sealing member through an opening of the cartridge assembly, and The above locking mechanism is, A skin beauty device comprising a mount tail extending from the above-mentioned pressure block toward the cartridge frame, and a tail insertion opening formed through the cartridge frame to allow the mount tail to enter.
3. In paragraph 2, The above-mentioned mount tail is extended to be inclined with respect to the lifting direction of the above-mentioned pressure block, and A skin beauty device in which the above-mentioned mount rail enters the above-mentioned tail insertion opening and contacts the rear wall of the above-mentioned cartridge frame to undergo elastic deformation.
4. In paragraph 3, Due to the elastic deformation of the above-mentioned mount tail, A skin beauty device in which the contact between the above-mentioned pressure block and the above-mentioned cartridge frame is strengthened.
5. In paragraph 1, When separating the above cartridge assembly from the above head part, A skin beauty device in which the above locking mechanism detaches from the rear of the cartridge frame.
6. In paragraph 5, The detachment of the above locking mechanism from the rear of the cartridge frame is, A skin care device that is automatically performed when the skin care agent contained in the agent receiving portion of the above-mentioned agent cartridge is depleted, or is performed by manual operation of an operation button provided in the above-mentioned main body.

Description

Skin care device having a locking mechanism for a replaceable cartridge The present invention relates to a skin beauty device comprising a replaceable cartridge, and more specifically, to a skin beauty device equipped with a locking mechanism that prevents the cartridge from being arbitrarily removed during use or from detaching due to impact. 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. FIG. 1 illustrates an example of a skin beauty device capable of satisfying these requirements. The skin beauty device of FIG. 1 is configured to be equipped with a detachable cartridge assembly. The cartridge assembly includes a semi-permanently used cartridge frame and a formulation cartridge that is replaceably mounted inside the cartridge frame. When the cartridge assembly is mounted, a dispensing mechanism provided inside the main body pressurizes the formulation cartridge, automatically dispensing a skin beauty agent. Therefore, the user can use the skin beauty device immediately without having to apply a skin beauty agent separately. In the skin beauty device of Fig. 1, the cartridge assembly is detached by sliding it toward the rear of the head part (based on the direction shown in the drawing). However, if the user arbitrarily removes the cartridge assembly before the skin beauty agent in the formulation cartridge is completely used up, there is a risk that the dispensing mechanism will be damaged. Additionally, the same problem occurs if the skin beauty device is dropped due to user negligence or mistake during use, or if the cartridge assembly becomes detached due to impact. Furthermore, if the cartridge assembly is removed during use, the skin beauty agent in the formulation cartridge may leak out, contaminating the inside of the skin beauty device, which may lead to malfunctions such as operational failure. 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.
