Description

Technical Field

[0001] The present invention relates to a household skin cleaner having an electro-cleaning function, and more particularly, to a household skin cleaner having both an electro-cleaning function of the skin achieved by supplying a galvanic current and a vibration function of the skin. Background Art

[0002] Skin beauty refers to the act of applying cosmetics or cleansing products to the skin, receiving skin massage, or removing foreign substances on the skin, thereby cleaning and aesthetically managing the skin. For skin beauty, recently, a method of applying a cleansing product evenly to the skin or cleansing the skin using a skin cleansing device with a rotating or vibrating brush has been adopted. For example, Korean Patent Publication No. 10-2017-0099518 and Korean Utility Model Registration No. 20-0489176 disclose a skin cleansing device that cleans or massages the skin by rotating a contact unit equipped with a brush that contacts the skin. In addition, Korean Patent No. 10-2324257 discloses a body cleansing device that supplies ultrasonic vibrations to a user by vibrating a brush unit using a vibration motor or vibrating an ultrasonic head using an ultrasonic oscillator.

[0003] On the other hand, during the metabolism of the skin, old waste is continuously generated and discharged. Therefore, it is necessary to appropriately remove this old waste to maintain the skin state cleanly. Recently, a galvanic beauty instrument that applies a galvanic stimulus to the skin to promote the separation of old waste by promoting blood circulation in the skin and expanding pores, and enhances the absorption effect of various lotions (liquid or mucinous) containing ingredients beneficial to the skin, thereby improving skin health, has been developed. A galvanic beauty instrument is used to contact an anode electrode and a cathode electrode with the skin to form a closed circuit, and selectively move cations or anions according to the polarity of the electrical stimulus, so that various lotions are absorbed by the skin, or old waste remaining on the skin is separated and removed. For example, through the iontophoresis method using galvanic current, the cathode electrode of a galvanic current generator pushes out anionic substances, inducing a saponification process caused by an alkaline reaction, thereby obtaining effects such as decomposing sebum and softening the skin. The iontophoresis method of active ingredients using galvanic current is disclosed in Korean Patent Publication No. 10-2012-0091335, Korean Patent Registration No. 10-2137437, US Patent Publication No. US2006-0015052, Korean Patent No. 10-1653292, etc. However, this electro-cleaning or iontophoresis of the skin using galvanic current generally has the disadvantages that it requires treatment by a specialized professional practitioner or requires the use of a specialized galvanic beauty instrument for treatment.

[0021] The present invention will be described in detail below with reference to the accompanying drawings. In the description of the present invention, specific descriptions of commonly used well-known functions or structures are omitted.

[0022] Figure 1 and Figure 2 are respectively the perspective view of the appearance and the partial internal structure diagram of a household skin cleaner with an electric cleaning function according to an embodiment of the present invention. As Figure 1 and Figure 2 shown, the household skin cleaner of the present invention includes a housing 10, a vibrating 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.

[0023] In the household skin cleaner of the present invention, the housing 10 can be set to a substantially cylindrical shape so that a user can hold one end of the skin cleaner by hand for use. The vibrating plate 20 and the vibration generating unit 22 are installed at one end, the handle 30 is installed at the other end, and the galvanic current supply unit 50 is provided inside. The housing 10 can be made of a hard synthetic resin or a synthetic resin with a predetermined elasticity, such as silicon, rubber, etc. If the side surface of the housing 10 combined with the vibrating plate 20 is made of a synthetic resin with a predetermined elasticity, the housing 10 absorbs or buffers the vibration of the vibrating plate 20, so it is preferred. As Figure 1 and Figure 2 shown, it is preferred that the vibrating plate 20 and the handle 30 are respectively formed at both ends of the housing 10 to prevent them from being adjacent to each other. In this way, when the vibrating plate 20 and the handle 30 are spaced apart, it is possible to prevent the vibration of the vibrating plate 20 from being directly applied to the hand of the user holding the handle 30 due to the direct contact of the hand of the user holding the handle 30 with the vibrating plate 20, or the current of the cathode electrode 42 from being directly applied to the hand of the user.

[0024] The vibration generating unit 22 generates vibrations to vibrate the vibrating plate 20, and the vibrating plate 20 contacts the user's skin and transmits vibrations. The vibration generating unit 22 can generate ultrasonic vibrations or mechanical vibrations. The ultrasonic vibrations can be generated using piezoelectric elements or the like, and the mechanical vibrations can be generated by a vibration motor, or by the interaction between a coil and a magnet. According to the vibration control signal applied to the vibration generating unit 22, the piezoelectric element, vibration motor, coil / magnet, etc. of the vibration generating unit 22 vibrate. Therefore, by adjusting the input mode, frequency, intensity, etc. of the vibration control signal, the vibration modes of the vibration generating unit 22 and the vibrating plate 20 can be adjusted. In an embodiment of the present invention, the vibration generating unit 22 can include a vibration motor, and through the rotation of the vibration motor, the vibrating plate 20 can vibrate in a direction perpendicular to the surface. In another embodiment of the present invention, the vibration generating unit 22 can include an ultrasonic generator that generates ultrasonic waves, and through the oscillation of the ultrasonic generator, the vibrating plate 20 acting as an ultrasonic head can generate ultrasonic vibrations in a direction perpendicular to the surface. On the surface of the vibrating plate 20, as a skin cleaning unit 24 that contacts the user's skin and massages or cleans the skin through friction, for example, a brush, sponge, cleaning towel, cleaning pad, protrusion, etc. can be formed. The vibrating plate 20 can have its edge fixed to the end of the lower surface of the housing 10 in a manner covering one end of the housing 10. The connection between the vibrating plate 20 and the housing 10 can be fixedly bonded through a normal adhesive, bonded through an elastic adhesive such as silicone, physically fitted, screwed, etc.

[0025] As Figure 1 and Figure 2 shown, the cathode electrode 42 can include a plurality of separated cathode electrodes 42a, 42b, 42c. Thus, when the cathode electrode 42 is composed of a plurality of separated cathode electrodes 42a, 42b, 42c, the galvanic current can be effectively supplied to the user's skin over a wider area. Figure 3 is an external perspective view of a household skin cleaner with an electric cleaning function according to another embodiment of the present invention. Except for the configuration structure of the cathode electrode 42, the skin cleaner of this embodiment has the same structure as the Figure 1 and Figure 2 shown embodiment. As Figure 3 shown, the cathode electrode 42 of this embodiment has a single plate shape formed on the surface of the vibrating plate 20. Thus, when the cathode electrode 42 has a single plate shape, the vibration of the vibrating plate 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 functions as a vibration surface at the same time, it preferably has a predetermined surface area, for example, 20% to 40% of the area of the vibrating plate 20.

[0026] The galvanic current supply unit 50, as a constant current source, receives a DC voltage and supplies a galvanic current with a uniform current intensity to the user's skin through the cathode electrode 42 and the anode electrode 44. The galvanic current refers to a minute current that enables various lotions to penetrate and be absorbed into the skin through iontophoresis, or is used to separate and remove old waste residues remaining on the skin. The cathode electrode 42 is installed at one end of the vibration plate 20, and the anode electrode 44 is installed on the handle 30. Preferably, the handle 30 is made of a conductive material and can perform the function of the anode electrode 44. When the user holds the handle 30 of the household skin cleaner of the present invention by hand and makes the vibration plate 20 contact the skin to be cleaned, the galvanic current generated by the galvanic current supply unit 50 flows through a closed loop composed 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 household skin cleaner of the present invention, the anode electrode 44 is located at one end of the skin cleaner held by the user, and the cathode electrode 42 is provided on the cleaning surface in contact with the skin, that is, the vibration plate 20. Therefore, while realizing the vibration function of the vibration cleaner, a galvanic current is also supplied to the skin.

[0027] Figure 4 It is a diagram showing an example of the galvanic current supply unit 50 that can be used in the household skin cleaner of the present invention. As Figure 4 shown, the galvanic current supply unit 50 includes a DC power supply 52 (DC supply) that supplies a DC voltage, a constant current supply source 54 that receives the DC voltage from the DC power supply 52 and outputs a voltage with a constant current value, and a load resistor R for adjusting the output current value of the constant current supply source 54 set . The constant current supply source 54 is a three-terminal adjustable current source that outputs a current with a constant value according to the size of the load resistor R set , and a general LM134 / LM234 / LM334 component (Texas instrument, USA) can be used. For example, in Figure 4 the shown galvanic current supply unit 50, the output current Iout = 67.8 mV / R set can be calculated.

[0028] Figure 5 It is a diagram showing another example of the galvanic current supply unit 50 that can be used in the household skin cleaner of the present invention. In Figure 5 the shown example, the DC power supply 52 is omitted and not shown. In Figure 4In the external circuit of the same constant current supply source 54 as shown, in addition to the load resistor (R1 = R set ), an additional resistor R2 and a diode (1N457) are added to eliminate the temperature dependence of the output current output by the galvanic current supply unit 50.

[0029] The household skin cleaner of the present invention can utilize Figure 4 and Figure 5 to supply a constant high-level constant current regardless of the skin state by the galvanic current supply unit 50 as shown. Figure 6 is a diagram showing an example of the galvanic current waveform supplied by the galvanic current supply unit 50 of the household skin cleaner of the present invention. As Figure 6 shown, the household skin cleaner of the present invention can supply a galvanic current waveform in the form of a pulse of 15 V or more to the user's skin by using a current of 500 μA, which is higher than that of the existing galvanic beauty instrument using a current of 100 μA.

[0030] When the user holds the handle 30 of the household skin cleaner of the present invention by hand and contacts the vibrating plate 20 of the skin cleaner with the skin of the user to be cleaned, and then starts the skin cleaner by wireless control or by using the start switch 12 installed on the skin cleaner, the galvanic current generated by the galvanic current supply unit 50 flows through a closed loop composed 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 addition, at the same time, the vibration generated by the vibration generating unit 22 causes the vibrating plate 20 to vibrate to transmit the vibration to the user's skin, thereby performing skin beauty. According to the household skin cleaner of the present invention, while providing vibration through the vibrating plate 20, the electric cleaning function of the skin can be realized through the cathode electrode 42 and the anode electrode 44 installed on the household skin cleaner.
