Technology Field
[0001] The present invention relates to a dual-focus ultrasonic skin care device, wherein, in massaging the face with ultrasonic and electrical stimulation, the electric electrode casing of the head part is designed in an ergonomic teardrop shape, and ultrasonic electrodes of different sizes are spaced apart and arranged therein, thereby enabling fine massage of the entire skin, especially narrow areas such as the eyes or between the eyebrows. Background Technology
[0002] With the recent surge in interest in skin care, the number of people visiting plastic surgery clinics, dermatology clinics, and skin care treatment centers is increasing.
[0003] However, such professional care is not only expensive but also requires time for travel and treatment, making it difficult for the average person who lacks both financial and time resources to receive skin care.
[0004] Accordingly, various beauty devices are being developed that allow for self-care at home.
[0005] One of these is a hand-grip type beauty device that can regenerate skin, restore elasticity, and increase the absorption rate of various functional cosmetics.
[0006] As a representative beauty device, there is a skin beauty device capable of water droplet lifting that applies micro-vibrations of ultrasound to the skin to aid in skin regeneration and restore elasticity.
[0007] There is another skin beauty device that has an absorption booster function, which stimulates the skin electrically to create temporary micro-channels, thereby increasing the penetration rate of active ingredients by tens of times.
[0008] However, most of these skin beauty devices have heads in the form of circular plates, so while they are effective for massaging the cheeks or forehead, they have the disadvantage of not being able to massage narrow areas such as the eyes or between the eyebrows in detail.
[0009] For reference, prior art related to this includes Registered Patent No. 10-2820948, etc. The problem to be solved
[0010] Accordingly, the present invention has been devised to solve the problems described above.
[0011] The purpose is to provide a dual-focus ultrasonic skin care device capable of finely massaging not only the cheeks and forehead but also narrow areas such as the eyes and between the eyebrows, by making the electric electrode casing forming the exterior of the head part into a teardrop shape, placing a relatively large first ultrasonic electrode in the wide part inside, and placing a relatively small second ultrasonic electrode in the narrow part. means of solving the problem
[0012] To achieve the above objectives, the dual-focus ultrasonic skin care device according to the present invention is,

[0018] It is characterized by including an electric electrode casing having a first exposure hole in a wide section and a second exposure hole in a narrow section, wherein the bracket is inserted and coupled from the rear side and each insulating section is fitted so that each ultrasonic electrode is exposed.
[0019] And in the dual-focus ultrasonic skin care device according to the present invention,
[0020] The head portion is coupled to the rear of the bracket and is characterized by including an operation PCB that is electrically connected to each ultrasonic electrode and an electric electrode casing, respectively.
[0021] Also, in the dual-focus ultrasonic skin care device according to the present invention,
[0022] The first ultrasonic electrode and the second ultrasonic electrode are electrically connected by contacting the front surface of the operating PCB, and
[0023] The first ultrasonic vibration element and the second ultrasonic vibration element are electrically connected by a first compression spring and a second compression spring interposed between the front surfaces of the operating PCB, and

[0038] For convenience in describing the dual-focus ultrasonic skin care device according to the present invention, a rough, non-strict directional standard is specified with reference to FIG. 1. The direction in which gravity acts is set downward, and the up, down, left, and right directions are determined as they appear. Unless otherwise specifically mentioned in the detailed description of the invention and claims related to other drawings, directions are described according to this standard.
[0039] Hereinafter, a dual-focus ultrasonic skin care device according to the present invention will be described with reference to the attached drawings.
[0040] As illustrated in FIGS. 1 to 6, the present invention relates to a dual-focus ultrasonic skin care device, which is largely composed of a head part (H) and a gripping part (M). Although the drawings typically show a home-use (portable) dual-focus ultrasonic skin care device in which all components for ultrasonic and electrical stimulation are built into the head part (H) and the gripping part (M), it may also be modified into a handpiece form connected to a separate main body by a cable.
[0041] First, the head part (H) mainly comprises a first ultrasonic electrode (10A), a second ultrasonic electrode (10B), a bracket (20), an electric electrode casing (30), and an operating PCB (40), and the gripping part (M) comprises an inner body (50), a control PCB (60), a sealing member (70), an outer body (80), and a main PCB (90).
[0042] Specifically, the head part (H)
[0043] A first ultrasonic electrode (10A) having a first mounting groove (11) on the rear side as a conductive material, and a first ultrasonic vibration element (13) attached to the first mounting groove (11),
[0044] A conductive material having a second mounting groove (12) on the rear side, and a second ultrasonic vibration element (14) attached to the second mounting groove (12), wherein the second ultrasonic electrode (10B) is smaller in size than the first ultrasonic electrode (10A).
[0045] A bracket (20) having a first fitting hole (21) and a second fitting hole (22) into which each ultrasonic electrode (10A) (10B) is respectively fitted and coupled, and a first insulating part (23) and a second insulating part (24) protruding along the front circumference of each fitting hole (21) (22) and covering the outer surface of each ultrasonic electrode (10A) (10B), made of a non-conductive material.
[0046] An electric electrode casing (30) having a conductive material having a left-right symmetrical teardrop shape composed of a wide section (31) and a narrow section (33) to form the exterior of the head section (H), wherein the bracket (20) is inserted and coupled from the rear side and each insulating section (23) (24) is fitted so that each ultrasonic electrode (10A) (10B) is exposed through a first exposure hole (32) of the wide section (31) and a second exposure hole (34) of the narrow section (33).
[0047] It includes an operation PCB (40) that is coupled to the rear surface of the bracket (20) and is electrically connected to each ultrasonic electrode (10A)(10B) and the electric electrode casing (30), respectively.
[0048] The above gripping part (M)
[0049] Inner body (50) having a withdrawal hole (52) formed therein,
[0050] A control PCB (60) having a switch (61) mounted at a position corresponding to the extraction hole (52) and coupled to the inner side of the inner body (50),
[0051] A sealing member (70) made of a flexible material that covers the circumference of the extraction hole (52) on the outer surface of the inner body (50) and presses the switch (61).
[0052] An outer body (80) that is fitted and coupled to the inner body (50) above to press the edge of the sealing member (70) and has a button (81) provided at a position corresponding to the sealing member (70), and
[0053] It includes a main PCB (90) coupled to the inner body (50) above.
[0054] In the drawing, a rechargeable dual-focus ultrasonic skin care device with a battery (B) built into the gripping part (M) can be seen, and the power supply design may vary.
[0055] The first ultrasonic electrode (10A) and the second ultrasonic electrode (10B) are manufactured from a conductive material such as titanium and have a cylindrical shape with an open rear end, the first ultrasonic electrode (10A) has a size corresponding to the width of the wide portion (31) of the electric electrode casing (30), and the second ultrasonic electrode (10B) has a size corresponding to the width of the narrow portion (33) of the electric electrode casing (30).
[0056] Each of these ultrasonic electrodes (10A)(10B) is electrically connected by attaching each ultrasonic vibration element (13)(14) to the inner surface of the front side of each mounting groove (11)(12), and each ultrasonic vibration element (13)(14) can be implemented as a piezoelectric element made of ceramic.
[0057] The above bracket (20) and electric electrode casing (30) are provided with corresponding droplet shapes, with each fitting hole (21)(22) and each exposure hole (32)(34) penetrating through them at locations corresponding to each ultrasonic electrode (10A)(10B).
[0058] The above bracket (20) is an injection-molded product made of a non-conductive material such as plastic, and each insulating part (23) (24) protrudes forward along the circumference of each fitting hole (21) (22), so that when each ultrasonic electrode (10A) (10B) and the bracket (20) are assembled to the electric electrode casing (30), each ultrasonic electrode (10A) (10B) and the electric electrode casing (30) are electrically separated from each other by each insulating part (23) (24).
[0059] At this time, the bracket (20) is made of a light-transmitting injection molded material so that light emitted from the LED element (46) of the operating PCB (40) can pass through each insulating part (23)(24) and be irradiated onto the front of the head part (H).
[0060] The above-mentioned operating PCB (40) receives power from the above-mentioned main PCB (90) and applies power to each ultrasonic vibration element (13)(14) and electric electrode casing (30) to generate ultrasonic and electroporation stimulation.
[0061] And the first ultrasonic electrode (10A) and the second ultrasonic electrode (10B) are electrically connected by contacting the front surface of the operation PCB (40).
[0062] The first ultrasonic vibration element (13) and the second ultrasonic vibration element (14) are electrically connected by a first compression spring (43) and a second compression spring (44) interposed between the front surfaces of the operation PCB (40).
[0063] The above electric electrode casing (30) is electrically connected by a bolt (45) that screws through the operating PCB (40) and the bracket (20).
[0064] First, the above-mentioned operation PCB (40) has ring-shaped pads (41) (42) corresponding to the rear ends of each ultrasonic electrode (10A) (10B) grounded on the front surface, so that when the head part (H) is assembled, each ultrasonic electrode (10A) (10B) comes into direct contact with the pads (41) (42) to establish an electrical connection.
[0065] And the above-mentioned operating PCB (40) has a silk line added to the center inside each pad (41)(42) to contact each compression spring (43)(44), thereby establishing an electrical connection between the operating PCB (40) and each compression spring (43)(44), and each compression spring (43)(44) makes physical contact by pressing each ultrasonic vibration element (13)(14) against each ultrasonic electrode (10A)(10B), thereby establishing an electrical connection between the operating PCB (40), each ultrasonic vibration element (13)(14), and each ultrasonic electrode (10A)(10B) through each compression spring (43)(44).
[0066] In addition, the electric electrode casing (30) is a casting product made of a conductive material such as aluminum, and has a boss portion and a screw hole formed therein for fastening bolts that penetrate the bracket (20) and the operating PCB (40). In particular, when a bolt (45) fitted into the operating PCB (40) is screwed into the boss portion (35), an electrical connection is made between the operating PCB (40) and the electric electrode casing (30) through the bolt (45).
[0067] To this end, the bracket (20) may have a cut portion formed so that the bolt (45) connected to the boss portion (35) does not come into contact, and in the case of the operating PCB (40), a pad is grounded at the part where the bolt (45) comes into contact.
[0068] In this way, by excluding wiring for electrical connection within the head part (H) and making electrical connection through mutual physical contact via assembly, the thickness of the head part (H) can be made thin.
[0069] Meanwhile, the above-mentioned operating PCB (40) has an LED element (46) mounted on its front surface and is irradiated through the insulating part (23)(24) to provide a skin beauty effect using the LED.
[0070] Next, the head part (H) is assembled to the mounting part (51) formed on the upper part of the inner body (50) of the gripping part (M), and the outer body (80) is slidably coupled to the inner body (50).
[0071] The inner body (50) and outer body (80) have a cylindrical shape and a structure that allows for mutual sliding connection.
[0072] The above inner body (50) is in the shape of a semi-cylindrical body excluding the battery (B) mounting part, and the main PCB (90) is coupled to the rear side thereof, and the control PCB (60) is coupled to the mounting part inside thereof.
[0073] And a display (53) that displays power on / off and function selection is mounted on the upper front of the above-mentioned outlet (52), and the display (53) is protected by a light-transmitting cover (82) that is coupled to the above-mentioned outer body (80), and the above-mentioned button (81) is exposed on the light-transmitting cover (82).
[0074] The above sealing member (70) seals the gap created by the button (81) and is interposed to cover the extraction hole (52) between the switch (61) and the button (81).
[0075] This sealing member (70) is made of a flexible material such as rubber or silicone, and transmits the push pressure of the button (81) to the switch (61) to be pressed, thereby sealing the area around the extraction hole (52) so that external water does not penetrate into the inner body (50).
[0076] At this time, a protrusion (54) is formed in a ring shape on the front circumference of the above-mentioned extraction hole (52), and the above-mentioned sealing member (70) includes a wing portion (61) in which an assembly groove is formed to which the protrusion (54) is fitted, thereby increasing airtightness.
[0077] In addition, the sealing member (70) further includes a sealing projection that protrudes along the front of the wing portion (61) and is pressed against the outer body (80).
[0078] When the gripping part (M) pushes the outer body (80) to slide into the inner body (50), the button (81) is coupled to the center of the sealing member (70). At this time, the inner surface of the outer body (80) presses the sealing projection, and the wing part (61) of the sealing member (70) is compressed, thereby completely sealing the gap around the button (81). A waterproof tape is attached to the contact surface between the outer body (80) and the light-transmitting cover (82), thereby achieving waterproof performance.
[0079] In describing the present invention above, the dual-focus ultrasonic skin care device has been described primarily with reference to the attached drawings; however, the present invention is capable of various modifications, changes, and substitutions by those skilled in the art, and such modifications, changes, and substitutions should be interpreted as falling within the scope of protection of the present invention.
