Abstract

The present invention relates to a face-lifting device, and more specifically relates to a face-lifting device wherein facial muscles are developed/strengthened by the rubbing of an electrode exposed outside a main body thereby imparting an electrical stimulus (low frequency region) to ligaments and SMAS (fascia) that maintain the cutaneous layer on the facial skeleton; the invention being adapted such that, based on the external shape (indentations, curvature and flatness) around the chin, cheeks, forehead, eyes and nose of the face and/or a nerve distribution chart, it is possible to either selectively use electrodes having differently disposed intervals and contacting surface areas or else to selectively use electrodes outputting different levels (strengths) and wavelengths of stimulus signal while being positioned at three-dimensionally different coordinates, and such that massaging and lifting take place optimised for various regions on the user's face or for the skin state of each user.

Description

Face lifting device

Technical Field

The present invention relates to a facial lifting device, and more particularly, to a facial lifting device which applies electrical stimulation (low frequency region) to ligaments and superficial muscular aponeurosis system (SMAS; fascia) that maintain a skin layer on facial bones by rubbing electrodes exposed to the outside of a subject, thereby growing/strengthening facial muscles. Electrodes disposed at three-dimensionally different coordinates and having mutually different intervals and contact surface areas, or electrodes outputting stimulation signals having mutually different levels (intensities) and wavelengths may be selectively used according to the external shape (concavity, curvature, and flatness) and/or nerve distribution around the chin, cheek, forehead, eyes, and nose of the face, so that improved massage and lifting of the areas of the face of the user or the skin condition of each user may be performed.

Background

In general, the epidermis layer of the skin protects the internal tissues of the body and prevents water from evaporating, and plays a very important role in preventing harmful substances such as bacteria from invading the skin from the outside. In other words, the water-soluble substance hardly permeates into the skin. Therefore, no matter how effective the cosmetic contains ingredients or how expensive the cosmetic is, the cosmetic cannot bring about satisfactory effects. In this case, a technique suitable for the skin care device is ion therapy (iontophoresis). Ionization therapy utilizes the electrical property that like polarities repel each other, helping to remove skin waste or to osmotically ionize the active ingredients of cosmetics. In the medical field, ion therapy has been used for about 300 years when drugs are infiltrated into the skin. Nowadays, ion therapy has an excellent effect on the treatment of freckles and wrinkles in the fields of dermatology and plastic surgery.

Meanwhile, another solution to protect facial skin from loss of elasticity while maintaining youthful appearance is to use cosmetics. However, below the stratum corneum layer of the skin epidermis, a protective wall is formed by a thick protein protective layer, and the epidermis layer and the dermis layer of the skin are separated by the protein protective layer. Therefore, even if a cosmetic having an excellent skin care effect due to the addition of a biomaterial is used, waste accumulated in the dermis layer cannot be removed, and the nutrition of the cosmetic may not penetrate deep into the dermis layer, so that the skin care effect is insufficient.

Therefore, various skin care devices for skin care using current ion flow, far infrared rays, or vibration have been known in recent years. The current ion flow is a current having a flow direction and level maintained constant regardless of time variation, which has excellent chemical effect, heating effect and vasomotion stimulating effect, and which always generates magnetic lines of force and heat to thereby achieve stimulation.

Hereinafter, a skin care device according to the related art will be described.

First, according to korean utility model registration No. 20-0326067 (Portable device for Skin-Care), filing date: 4/24/2003), the Skin Care device includes: a handle 11; an upper body 13 extending from the handle 11; a plurality of metal plates formed on the front end 14 of the upper body 13 and serving as electrodes through which low-frequency current (anions and cations) flows when the metal plates are in contact with the skin (face) of a user; and an operation panel 20 formed on one side surface of the upper body 13, wherein the metal plates P1, P2, and P3 are arranged such that an interval between the first metal plate P1 and the second metal plate P2 and an interval between the second metal plate P2 and the third metal plate P3 are different from each other.

In the conventional portable skin care device, low frequency currents (anions and cations) flow in various forms through a plurality of conductive metal plates in contact with the skin, which may contribute to skin regeneration and functional recovery of a user to perform skin care, and the metal plates are arranged at various intervals while the flow of the current is controlled accordingly to make the metal plates in contact with the skin according to the area of the skin.

However, in the conventional portable skin care device, the metal plate is disposed on the flat surface of the main body side, and thus proper massage cannot be performed according to the external shape (concavity, curvature and flatness) around the chin, cheek, forehead, eyes and nose of the face. In other words, it may not be difficult to massage a large flat area such as the forehead or cheek, and for a deeply depressed and curved area such as around the nose, since it is difficult to massage such an area, there is insufficient stimulation or insufficient stimulation to such an area, and thus the massage effect is low.

Subsequently, according to Korean patent publication No. 10-2006-0000723 (skin care device with a multimodal Function (SkinCare Apparatus Having Multi-Mode Function), filing date: 6.29.2004), a skin care device with a multimodal Function includes: a battery unit 110 for supplying operating power; a power supply and variable switching unit 120 connected to the output terminal of the battery unit 110 and including a power supply and a variable switch for supplying or cutting off power to or from the device and controlling the output intensity of the power; a control unit 130 operated by power input from the power supply and variable switch unit 120 and having a control program of a multi-level mode to perform a massage function, a pulling function, a lymphatic drainage function, and an anti-aging function, thereby controlling output of low-frequency anion or cation current by an Electrical Muscle Stimulation (EMS) signal in four levels; an output control unit 140 that generates and outputs a low-frequency current according to an output control signal of the control unit 130; an output device 150 that outputs a low-frequency current through the pair of output terminals 12 and 13 according to an output signal of the output control unit 140, wherein the output is performed by adding or subtracting the intensity of the current flowing through the output terminals 12 and 13 according to a variable signal input through the power supply and variable switching unit 120; and a selection switch unit 160 connected to the control unit 130 and including a selection switch to input a key command of the selection switch to the control unit 130.

According to the conventional skin care device having multi-mode functions including an ion massage function, a lifting function, a lymphatic drainage function, and an anti-aging function, a compact skin care device can perform various functions of stimulating a muscle layer to improve a muscular status, promote blood circulation and lymphatic circulation, enhance decomposition of fats and wastes, relieve blood blockage, and alkalize blood, wherein the skin care device is programmed to perform the following processes: under the condition of not carrying out low-frequency stimulation, by changing the frequency, the conduction time and the conduction times of low-frequency waves, the hand massage or the control of acupuncture points is realized in four complicated operation functions.

However, in the conventional skin care device having the multi-mode function, a flat head for outputting ions and ultrasonic waves is provided at one side of the main body, and thus proper massage cannot be performed according to the external shape (concavity, curvature and flatness) of the chin, cheek, forehead, eyes and nose of the face. Further, even if the same electrical stimulation is applied, the stimulation level (intensity) differs depending on the distribution of the nerve, so the electrical stimulation must be applied at a level suitable for each area. However, since the above skin care device is programmed to sequentially perform a plurality of levels of functions, the entire face may be massaged, so that excessive stimulation or edge stimulation may be applied to each face area, and thus the skin may be considerably stressed, or the massage effect may be low.

For reference, it is noted in advance that the reference numerals of the related art described above correspond to those in the related publications, and therefore the reference numerals of the related art described above should not be confused with those of the present invention.

Finally, the invention comprises a power supply unit comprising, as electrical components, a power supply circuit for supplying a rated power. However, since the power supply unit is a general-purpose component in the configuration including the circuit, and the power supply unit does not have a special function in the present invention, the power supply unit will not be specifically shown and described.

Hereinafter, the operation of the present invention configured as described above will be described.

As shown in fig. 1, the present invention may provide a facial lifting device 10 for electrically stimulating skin by means of an electrode, which is a conduction path of a skin stimulation signal, wherein a first electrode 13 and a second electrode 14 are disposed at three-dimensionally different coordinates with reference to a common electrode 12 disposed at one side of a main body 11, and an interval and a contact surface area of the first electrode 13 to the common electrode 12 are different from an interval and a contact surface area of the common electrode 12 to the second electrode 14.

As described above, the first electrode 13 and the second electrode 14 are disposed at three-dimensionally different coordinates with the common electrode 12 as a reference, and the interval and the contact surface area of the first electrode 13 to the common electrode 12 are different from those of the common electrode 12 to the second electrode 14. For example, the interval of the first electrode 13 to the common electrode 12 may be 3mm to 20mm, and the contact surface area of the first electrode 13 to the common electrode 12 may be 0.1cm²～3cm²The interval of the common electrode 12 to the second electrode 14 may be 10mm to 50mm, and the contact surface area of the common electrode 12 to the second electrode 14 may be 1cm²～4cm²。

When the distance between the first electrode 13 and the common electrode 12 is 3 mm-20 mm, the contact surface area between the first electrode 13 and the common electrode 12 is 0.1cm²～3cm²When, as shown in fig. 4a), a portion having a narrow surface area or a deep concave portion such as the periphery of eyes or nose can be easily stimulated. When sharing the electrodeThe interval between the common electrode 12 and the second electrode 14 is 10 mm-50 mm, and the contact surface area between the common electrode 12 and the second electrode 14 is 1cm²～4cm²When, as shown in fig. 4b), a portion having a large surface area or a portion not deeply depressed such as the forehead, cheek, neck, or periphery of the chin can be easily stimulated.

According to the present invention configured as described above, it is possible to select electrodes having intervals suitable for concavity, curvature and flatness according to the external shape around the chin, cheek, forehead, eyes and nose of the face to perform massage or lifting stimulation, and to perform electrode selection by automatic ON/OFF switching (simple and quick switching) performed by changing only the direction of the main body 11 with the common electrode 12 as a reference, without operating a switch or sequentially operating a program.

More specifically, the supporting ligament extends from the facial bone to the skin layer to hold and support the skin in a range from the inside to the outside of the skin, and as shown in fig. 5, the Surface Muscular Aponeurosis System (SMAS), the tenosynovium layer (also called facial expressive muscle layer) is disposed under the adipose layer of the skin to connect and hold the skin and the muscle. With age, the aging phenomena weaken or lose elasticity of the supporting ligaments or the SMAS layer, which leads to a slackening of the skin. When the facial lifting device 10 of the present invention is used for massage or lifting, facial muscles are strengthened by low frequency stimulation, and fascia ligaments are also strengthened, so that the lifting effect as shown in fig. 6 can be obtained.

Further, the present invention may preferably provide a facial lifting device 10 for electrically stimulating skin by means of an electrode serving as a conduction path of a skin stimulation signal, wherein the first electrode 13 and the second electrode 14 are disposed on three-dimensionally different coordinates with reference to the common electrode 12 disposed on one side of the main body 11, and the interval and the contact surface area of the first electrode 13 to the common electrode 12 are different from those of the common electrode 12 to the second electrode 14, and the level and the wavelength of the stimulation signal supplied from the first electrode 13 to the common electrode 12 are different from those of the stimulation signal supplied from the common electrode 12 to the second electrode 14 according to a preset control signal.

As described above, according to the present invention, the level and wavelength of the stimulus signal supplied from the first electrode 13 to the common electrode 12 are different from those of the stimulus signal supplied from the common electrode 12 to the second electrode 14 according to the preset control signal. For example, the first electrode 13-the common electrode 12 may allow a low current to flow, stimulating areas of thin skin layer such as around the eyes, and the common electrode 12-the second electrode 14 may allow a relatively higher current to flow, stimulating areas of thick skin layer such as the cheeks.

Thus, massage and pull stimulation may be performed using stimulation signals having levels and wavelengths appropriate for the nature of the skin or for the depth of the skin layer and ligaments and nerves located below the skin layer.

According to the present invention configured as described above, with the stimulus signal having the level and wavelength suitable for the state and depth of the skin at each region of the face other than the skin layer, the lifting effect can be truly achieved by reinforcing the fascia and supporting ligaments under the subcutaneous fat.

Further, the present invention may preferably provide a facial lifting device 10 for electrically stimulating skin by means of an electrode serving as a conduction path of a skin stimulation signal, wherein the first electrode 13 and the second electrode 14 are disposed on three-dimensionally different coordinates with reference to the common electrode 12 disposed at one side of the main body 11, the interval and the contact surface area of the first electrode 13-the common electrode 12 are different from those of the common electrode 12-the second electrode 14, and the stimulation signal is applied to only one of the first electrode 13-the common electrode 12 and the common electrode 12-the second electrode 14 which are in contact with the skin, and is not applied to the other of the first electrode 13-the common electrode 12 and the common electrode 12-the second electrode 14.

As described above, according to the present invention, a stimulation signal is applied to only one of the first electrode 13-the common electrode 12 and the common electrode 12-the second electrode 14, which are in contact with the skin, so as to, for example, identify the electrode in contact with the skin to form a conduction path (to measure a conduction current and resistance), and output the stimulation signal having a level and a wavelength preset for the electrode.

Therefore, it is possible to obtain the applicability improvement effect that enables the face pulling device to be conveniently and selectively used without operating a separate switch.

Further, according to the present invention, the main body 11 disposed between the common electrode 12 and the second electrode 14 may have an LED or light source 15 for providing heat, ultraviolet radiation, or far infrared radiation such as a lamp, and the LED or light source 15 provided separately or in combination can apply thermal skin stimulation such as heat, ultraviolet radiation, or far infrared radiation to the skin, so that heat and ultraviolet radiation or far infrared radiation are applied to the face during massage and lifting, and thus the face can be warmed, and the sterilizing effect and blood circulation of the face can be improved.

Furthermore, the invention may comprise a control unit 16, the control unit 16 comprising control circuitry and a microprocessor with a program for: the stimulation signal generation unit 17 is controlled to measure the state of the skin (depth, moisture content, etc.) by detecting the current and resistance conducted via the electrodes in contact with the skin, and to output a stimulation signal having a level and wavelength preset according to the measured value; or when a current path from the skin to the first electrode 13-the common electrode 12 is formed or a current path from the skin to the common electrode 12-the second electrode 14 is formed, the stimulation signal generating unit 17 is controlled to output a stimulation signal having a level or wavelength preset according to the current path. When the main body 11 has an LED or light source 15 for providing heat, ultraviolet radiation or far infrared radiation, the provision of the LED or light source 15, individually or in combination, enables the application of thermal skin stimulation such as heat, ultraviolet radiation or far infrared radiation to the skin, the control unit 16 preferably further comprises a program controlling the selective or sequential turning on of the light source 15.

According to the present invention as described above, when the user turns on the power source of the face pulling device 10, the face pulling device 10 is in an operable state (start) for massage and pulling, and when the electrode area is in contact with the skin of the face in the above state, the control unit 16 detects the current conducted via the electrodes and the resistor in contact with the skin, thereby performing skin measurement for measuring the skin state (depth, moisture content, etc.), as shown in fig. 7. At this time, skin measurement may be performed at one or both of the first electrode 13-the common electrode 12 and the common electrode 12-the second electrode 14, which may be preset or selected in the skin measurement process. When a skin measurement signal is input in the skin measurement stage, the control stimulation signal generation unit 17 compares the measurement value with a preset comparison value and outputs a stimulation signal having a level and wavelength corresponding to the measured skin.

At this time, the stimulation signal generation unit 17 outputs a stimulation signal according to a preset value for each of the first electrode 13-the common electrode 12 and the common electrode 12-the second electrode 14. Therefore, the level and wavelength of the stimulation signal can be set according to the skin of each user, and the level and wavelength of the stimulation signal can be set for each area of the face of the same user, thereby performing massage and lifting with the stimulation signal having the level and wavelength suitable for the skin condition of various users and each face area of the same user.

The massage and pulling operation is completed by continuing the massage and pulling operation as described above for a preset time or by continuing the massage and pulling operation as described above until the user operates the stop button.

As described above, although the exemplary embodiments of the present invention have been shown and described for illustrative purposes, the present invention is not limited to the configurations and operations shown and described above.

It will be apparent to those skilled in the art that many modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims.

Accordingly, all such suitable modifications and variations as well as equivalents may be resorted to, falling within the scope of the invention.
