BEST MODE FOR DISCLOSURE

(7) Devices for skin care or treatment are implemented in a variety of ways. The skin is subjected to minute stimuli to change the activity of cells, which can lead to improved skin effects on wrinkles, whitening, etc.

(8) One of the most representative forms is the noninvasive form of giving electrical impulses to the skin, or the invasive form of giving physical stimuli.

(9) Although a device of an individually portable type was not available conventionally, as the development of wireless communication and the downsizing of components have become more common in recent years, portable care devices are popularly commercialized.

(10) FIG. 1 is a perspective diagram of a skin care device 100 working on a deep part and surface of a human skin related to the present disclosure. The skin care device 100 according to the present disclosure includes a grip part 110 gripped by a user with a hand and a head part 120 having a skin contact plate 121 located at an end portion of the grip part 110 to contact with a user's skin. When a user applies a force to the skin contact plate 121 to touch a face, the grip part 110 and the head part 120 may form angles between 90˜180 degrees for facilitation.

(11) The grip part 110 may include a space inside to receive a battery 190 as a power supply part and a printed circuit board 180 as a controller therein, and a manipulating part 115 for manipulation of power-on/off may be provided to an outer surface of the grip part 110. Additionally, a display part displaying a current operational state may be included. The display part may employ a way of displaying a color of a lamp simply or a way of displaying texts or symbols like LCD.

(12) A power connection part for connecting an external power source may be included in the grip part 110. If the battery 190 is not provided, the power connection part may adopt a way of supplying permanent power. If the battery 190 is provided, the power connection part plays a role in charging the battery 190. The charging may be performed in a manner of supplying power by connecting a charger supplied with external power through a terminal or using wireless charging.

(13) As the head part 120 is directly touched with user's skin, it should be equipped with a waterproof structure to prevent particles from entering an inside of the head part 120. The head part 120 includes a skin contact plate 121 contacting with user's skin. And, the skin care device 100 of the present disclosure is characterized in having a plurality of the skin contact plates 121.

(14) In the related art, a single skin contact plate is used to supply ultrasonic waves of a single wavelength, but the skin care device 100 of the present disclosure is characterized in having the head part 120 that provides vibrations in various ultrasonic bands owing to the difference in wavelength having a good absorption rate depending on the ingredients of cosmetics.

(15) As shown in FIG. 1, a first skin contact plate 121a and a second skin contact plate 121b located around a circumference of the first skin contact plate 121a in a ring shape are provided. And, a third skin contact plate 121c located around a circumference of the second skin contact plate 121b may be provided. Moreover, two or more skin contact plates 121 may be provided. Each of the skin contact plates 121 may apply ultrasonic waves on different frequency bands by vibrators vibrating in different wavelengths, respectively. For example, a first vibrator 130a may vibrate with ultrasonic wave of 280 kHz, a second vibrator 130b may vibrate with ultrasonic wave of 350 kHz, and a third vibrator 130c may vibrate with ultrasonic wave of 1 MHz.

(16) A connecting part 122 of ductile material may be provided between the skin contact plates 121, and is capable of a waterproof function to prevent water and the like from flowing into a gap between the connecting part 122 and the skin contact plate 121. The skin contact plate 121 may be connected using a structure such as a hinge. In this case, it is necessary to perform waterproof treatment between the skin contact plates 121.

(17) FIG. 2 is a diagram showing one embodiment of an inside of the head part 120 of the skin care device 100 related to the present disclosure, and FIG. 3 is a cross-sectional diagram showing one embodiment of the head part 120 of the skin care device 100 related to the present disclosure. Since each of the second and third skin contact plates 121b and 121c has an sufficient space for coupling an vibrator thereto except the first skin contact plate 121a located at the center of the skin contact plates 121 disposed in a concentric circle shape [FIG. 1], a second vibrator 130b and a third vibrator 130c may be disposed in a second vertical direction [FIG. 2, FIG. 3].

(18) A first support plate 131b connected to the second skin contact plate 121b through a connecting leg 132 and a second support plate 131c connected to the third skin contact plate 121c through the connecting leg 132 are included. Since the first support plate 131b is smaller than the second support plate 131c, it may be located inside the connecting leg 132 connecting the second support plate 131c and the third skin contact plate 121c together. The second vibrator 130b applying vibration to the second skin contact plate 121b may be seated on the first support plate 131b, and the third vibrator 130c applying vibration to the third skin contact plate 121c may be seated on the second support plate 131c. The connecting leg 132 is not formed in a cylindrical shape but has a shape in which a plurality of legs are connected together, whereby electric wires connecting the vibrators, the skin contact plates 121 and the printed circuit board may be disposed between the connecting legs 132.

(19) Each of the support plates 131b and 131c may include a fixing part 133 formed of ductile material provided to a case forming an exterior of the head part 120 so as to be stably fixed thereto. As the connecting part 122 located between the skin contact plates 121 or the fixing parts are formed of the ductile material, it is able to reduce the effect caused to another skin contact plate 121 by the vibration generated from each vibrator.

(20) FIG. 4 is a diagram showing another embodiment of a head part 120 of a skin care device 100 related to the present disclosure, and FIG. 5 is a front diagram showing another embodiment of the head part 120 of the skin care device 100 related to the present disclosure.

(21) Referring to FIG. 4 and FIG. 5, a skin contact plate 121 of a skin care device may have a sector shape generated from sectoring a circular shape. As shown in FIG. 5, the skin contact plate may be divided into three equal parts or more. Alternatively, circular skin contact plates 121 may be disposed side by side. According to the present embodiment, unlike the former embodiment, one skin contact plate 121 may be formed to have thickness enough for a vibrator to be seated thereon and, as shown in FIG. 4, a vibrator may be directly seated on the skin contact plate 121. According to the former embodiment, a size of the head part 120 can be reduced but thickness thereof increases. On the contrary, according to the present embodiment, the thickness of the head part 120 can be reduced.

(22) As mentioned in the description of the former embodiment, sine the connecting part 122 of the ductile material is inserted between the skin contact plates 121, each of the skin contact plates 121 may vibrate with ultrasonic wave of a different frequency. As shown in FIG. 5, the connecting part 122 may be provided between the case forming the exterior of the head part 120 and the skin contact plate 121 as well as between a plurality of the skin contact plates 121.

(23) As the connecting part 122 has elasticity, it may reduce interference between vibrations applied to the skin contact plates 121, respectively and each of the skin contact plates 121 may move individually. If each of the skin contact plates 121 moves individually, it may be inclined at a difference angle along a curved surface of a face, whereby the effect of adherence between the skin contact plate 121 and a user skin can be increased.

(24) FIG. 6 is an exploded perspective diagram of a tip head of the skin care device 100 related to the present disclosure. The skin contact plate 121 of the present disclosure is formed of conductive material and has one pole connected to the controller 180. Namely, the first skin contact plate 121a is connected to the + pole and the second skin contact plate 121b is connected to the − pole. If there are four or more skin contact plates 121, each of the skin contact plates 121 is connected to one pole.

(25) The application of microcurrent to the user's skin improves the skin penetration effect of the vitamin-like molecules with polarity along the current, allowing cosmetics ingredients to pass through the epidermis 11 to the dermis 12. The + and − poles should be connected to separate conductors as the + and − pole connections to one electrode cause the current to flow back to the opposite polar direction rather than through the user's body.

(26) As the conventional skin contact plate 121 consists of one conductor, it uses the principle that current flows through the skin when held by hand in a manner of exposing the electrode part to the grip part 110. However, since the present disclosure includes a plurality of skin contact parts, if they are connected to different poles, respectively, as shown in FIG. 6, the current flows from the first skin contact plate 121a to the second skin contact plate 121b through the skin.

(27) The skin care device 100 of the present disclosure does not need to have a separate electrode part provided to the grip part 110. As current passes through only the area adjacent to a contacted skin, the cosmetics ingredients can penetrate the skin without the current needlessly passing through a body.

(28) As described above, according to at least one of embodiments of the present disclosure, the absorption rate of cosmetics mixed with different ingredients can be raised. In addition, a user can be relieved of the inconvenience of holding onto and using a separately provided electrode.

(29) Those skilled in the art will appreciate that the present disclosure may be carried out in other specific ways than those set forth herein without departing from the spirit and essential characteristics of the present disclosure.

(30) The above embodiments are therefore to be construed in all aspects as illustrative and not restrictive. The scope of the disclosure should be determined by the appended claims and their legal equivalents, not by the above description, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
