Description

[Technical Field]

[0001] The present invention relates to a home skin cleansing device with an electric cleansing function, and more particularly to a home skin cleansing device that simultaneously has the functions of electric skin cleansing and skin vibration by supplying a galvanic current. [Background technology]

[0002] Skin beauty treatments involve applying cosmetics or cleansing products to the skin, massaging the skin, and removing impurities from the skin to keep the skin clean and beautiful. Recently, skin cleansing devices with rotating or vibrating brushes have been used to evenly apply cleansing products to the skin and cleanse the skin. For example, Korean Patent Publication No. 10-2017-0099518 and Korean Utility Model Registration No. 20-0489176 disclose skin cleansing devices that cleanse or massage the skin by rotating a contact unit equipped with a brush that comes into contact with the skin. Korean Patent Registration No. 10-2324257 also discloses a body cleansing device that vibrates a brush unit using a vibration motor or an ultrasonic head using an ultrasonic vibrator to provide ultrasonic vibrations to the user.

[0003] Meanwhile, waste products are continuously produced and excreted during skin metabolism, and proper removal is essential to maintain clean skin. Recently, galvanic beauty devices have been developed that apply galvanic electrical stimulation to the skin to promote blood circulation and dilate pores, thereby facilitating the separation of waste products and enhancing the absorption of various skin lotions (liquid or viscous) containing beneficial ingredients, thereby promoting skin health. Galvanic beauty devices form a waste circuit by contacting an anode and a cathode electrode with the skin. Depending on the polarity of the electrical stimulation, cations or anions are selectively transferred, allowing various skin lotions to be absorbed into the skin or separating and removing remaining waste products. For example, iontophoresis using galvanic current can push anionic substances through the cathode electrode of a galvanic current generator, inducing a saponification process through an alkaline reaction, resulting in effects such as sebum decomposition and skin softening. Iontophoresis of active ingredients using galvanic current is disclosed in Korean Patent Publication No. 10-2012-0091335, Korean Patent Registration No. 10-2137437, U.S. Patent Publication No. US 2006-0015052, Korean Patent Registration No. 10-1653292, etc. However, such electrical cleansing or iontophoresis of the skin using galvanic current has the disadvantage that it generally must be performed by a separate professional or using a separate dedicated galvanic beauty device.

[Figure 6] 3 is a diagram showing an example of a galvanic current waveform supplied from a galvanic current supply unit 50 of the home skin cleansing device according to the present invention. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings. In the description of the present invention, a detailed description of commonly used and well-known functions or configurations will be omitted.

[0011] 1 and 2 are an external perspective view and a partial internal structural view, respectively, of a home skin cleansing device with an electric cleansing function according to one embodiment of the present invention. As shown in Figures 1 and 2, the home skin cleansing device according to the present invention includes a housing 10, a vibration plate 20, a vibration generating unit 22, a handle 30, a galvanic current supply unit 50, a cathode electrode 42, and an anode electrode 44.

[0012] In the home skin cleansing device of the present invention, the housing 10 is generally cylindrical so that a user can hold one end of the skin cleansing device with their hand. The housing 10 has a vibration plate 20 and a vibration generating unit 22 attached to one end and a handle 30 attached to the other end, and a galvanic current supply unit 50 installed inside. The housing 10 may be made of a hard synthetic resin or a synthetic resin having a predetermined elasticity, such as silicone or rubber. It is preferable that the side of the housing 10 that is coupled to the vibration plate 20 is made of a synthetic resin having a predetermined elasticity, since the housing 10 absorbs or damps the vibration of the vibration plate 20. As shown in FIGS. 1 and 2, the vibration plate 20 and the handle 30 are preferably formed on both ends of the housing 10 so as not to be adjacent to each other. In this way, if the vibration plate 20 and the handle 30 are spaced apart, it is possible to prevent the user's hand holding the handle 30 from coming into direct contact with the vibration plate 20, and to prevent the vibration of the vibration plate 20 from being directly applied to the user's hand, or the current of the cathode electrode 42 from being directly applied to the user's hand.

[0013] The vibration generating unit 22 generates vibrations to vibrate the diaphragm 20, which transmits the vibrations by contacting the user's skin. The vibration generating unit 22 may generate ultrasonic vibrations or mechanical vibrations. Ultrasonic vibrations may be generated using a piezoelectric element, and mechanical vibrations may be generated by a vibration motor or by the interaction between a coil and a magnet. A vibration control signal applied to the vibration generating unit 22 causes the piezoelectric element, vibration motor, coil / magnet, etc. of the vibration generating unit 22 to vibrate. The vibration pattern of the vibration generating unit 22 and the diaphragm 20 can be adjusted by adjusting the input pattern, frequency, intensity, etc. of the vibration control signal. In one embodiment of the present invention, the vibration generating unit 22 may include a vibration motor, and rotation of the vibration motor may cause the diaphragm 20 to vibrate in a direction perpendicular to the surface. In another embodiment of the present invention, the vibration generating unit 22 may include an ultrasonic generator that generates ultrasonic waves, and oscillation of the ultrasonic generator may cause the diaphragm 20, which serves as an ultrasonic head, to ultrasonically vibrate in a direction perpendicular to the surface. The surface of the vibration plate 20 may be provided with a skin cleansing portion 24 that comes into contact with the user's skin to massage or cleanse the skin through friction, and may be formed with, for example, a brush, sponge, towel, cleaning pad, protrusions, etc. The vibration plate 20 may have its edge fixed to an end of the lower surface of the housing 10 so as to cover one end of the housing 10. The vibration plate 20 and the housing 10 may be connected to each other by a conventional adhesive, an elastic adhesive such as silicone, physical fitting, screw connection, etc.

[0014] As shown in FIGS. 1 and 2, the cathode electrode 42 may include a plurality of separate cathode electrodes 42a, 42b, and 42c. When the cathode electrode 42 includes a plurality of separate cathode electrodes 42a, 42b, and 42c, a galvanic current can be efficiently supplied to the user's skin over a wider area. FIG. 3 is a perspective view of a home skin cleansing device with an electric cleansing function according to another embodiment of the present invention. The skin cleansing device according to this embodiment has the same structure as the embodiment shown in FIGS. 1 and 2, except for the arrangement of the cathode electrode 42. As shown in FIG. 3, the cathode electrode 42 according to this embodiment has a single plate shape formed on the surface of the diaphragm 20. When the cathode electrode 42 has a single plate shape, the vibration of the diaphragm 20 and the galvanic current can be more efficiently transmitted to the user's skin simultaneously through the cathode electrode 42. In this case, since the cathode electrode 42 also serves as a vibrating surface, it preferably has a predetermined surface area, for example, 20 to 40% of the area of ​​the diaphragm 20.

[0015] The galvanic current supply unit 50 is a constant current source that receives a DC voltage and supplies a galvanic current of uniform current intensity to the user's skin through the cathode electrode 42 and the anode electrode 44. Galvanic current refers to a minute current used to penetrate and absorb various lotions into the skin through iontophoresis, or to separate and remove waste products remaining on the skin. The cathode electrode 42 is attached to one end of the vibration plate 20, and the anode electrode 44 is attached to the handle 30. Preferably, the handle 30 is made of a conductive material and can function as the anode electrode 44. When a user holds the handle 30 of the home skin cleansing device of the present invention with their hand and brings the vibration plate 20 into contact with the skin to be cleansed, the galvanic current generated by the galvanic current supply unit 50 flows through a closed circuit consisting of the cathode electrode 42, the user's skin, the user's hand, and the anode electrode 44, and is transmitted to the user's skin. In the home skin cleansing device according to the present invention, an anode electrode 44 is located at one end of the skin cleansing device held by the user, and a cathode electrode 42 is located on the cleansing surface that comes into contact with the skin, i.e., the vibration plate 20, so that a galvanic current is supplied to the skin simultaneously with the vibration function of the vibration cleansing device.

[0016] 4 is a diagram showing an example of a galvanic current supply unit 50 used in the home skin cleansing device according to the present invention. As shown in FIG. 4, the galvanic current supply unit 50 includes a DC power supply 52 for supplying a DC voltage, a constant current supply source 54 for receiving a DC voltage from the DC power supply 52 and outputting a voltage of a constant current value, and a load resistor (R set The constant current source 54 includes a load resistor (R set) and can use ordinary LM134 / LM234 / LM334 elements (Texas Instruments, USA). For example, in the galvanic current supply unit 50 shown in FIG. 4, the output current Iout=67.8 mV / R set It can be calculated as:

[0017] 5 is a diagram showing another example of a galvanic current supply unit 50 used in a home skin cleansing device according to the present invention. In the example shown in FIG. 5, the DC power supply 52 is not shown, and a load resistor (R1=R set ) an additional resistor (R2) and a diode (1N457) are added to eliminate the temperature dependency of the output current output from the galvanic current supply unit 50.

[0018] The home skin cleansing device according to the present invention can supply a constant high-quality constant current regardless of the skin condition using a galvanic current supply unit 50 as shown in Figures 4 and 5. Figure 6 is a diagram showing an example of a galvanic current waveform supplied from the galvanic current supply unit 50 of the home skin cleansing device according to the present invention. As shown in Figure 6, the home skin cleansing device according to the present invention can supply a pulse-type galvanic current waveform of 15 V or more to the user's skin using a current of 500 μA, which is higher than that of existing galvanic beauty devices that use a current of 100 μA.

[0019] A user holds the handle 30 of the home skin cleansing device according to the present invention with their hand, brings the vibration plate 20 of the skin cleansing device into contact with the user's skin to be cleansed, and then activates the skin cleansing device using a wireless control or an activation switch 12 attached to the skin cleansing device. The galvanic current generated by the galvanic current supply unit 50 flows through a closed circuit consisting of the cathode electrode 42, the user's skin, the user's hand, and the anode electrode 44, and is transmitted to the user's skin. At the same time, vibrations generated by the vibration generator 22 vibrate the vibration plate 20, which is then transmitted to the user's skin, thereby performing skin beautification. The home skin cleansing device according to the present invention can realize an electrical cleansing function for the skin through the cathode electrode 42 and the anode electrode 44 attached to the home skin cleansing device, in addition to the vibrations provided by the vibration plate 20.
