Description

{PORTABLE SKIN CARE APPARATUS WITH COLOR THERAPY FUNCTION WITH COLOR THERAPY FUNCTION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable skin beauty device, and more particularly to a portable skin care device using ultrasonic waves for skin.

When a portable beauty device using ultrasonic waves is used to remove skin hairs, water or a lotion is applied to the skin, and a blade (diaphragm) is put on the skin and used. At this point, water or lotion can penetrate through the point where the blade is exposed to the front. Therefore, portable beauty equipment using ultrasonic waves is generally accompanied by a waterproof structure.

The inventor of the present invention has manufactured a portable beauty device using ultrasonic waves. Korean Patents No. 607148, No. 856345, and No. 1459338, the company continuously strives to develop and improve new technologies. In order to improve the performance of the portable skin beauty device and to fuse the different technologies, the inventors investigated the technique of irradiating the light source to the skin in a process of constant research. Korean Patent No. 1349157, for example, proposes a skin treatment method using an LED light beam, and introduces various background technologies related to a light source of a light source.

However, various technical challenges have been encountered in fusing LED light source technology to ultrasound skin beauty devices with metal blades. Such as waterproofing, placement problems, ultrasonic vibrations through the blades, problems with the direction of the light source, and problems with the delivery efficiency of the light source. The invention of the present invention has been studied for a long time in order to solve this problem effectively, and after the hard work, the present invention has been completed.

COLOR THERAPY skin beauty using high-brightness LED is known. Color therapy is to promote skin beauty by activating skin metabolism by irradiating short and strong light on skin.

In order to incorporate these color therapy functions into a portable beauty device, it is essential to design a device that is excellent in a waterproof structure. It may be desirable to structurally provide an LED for color therapy to the front of the beauty device to illuminate both the LED light in the blade direction and the top surface of the housing. However, in disposing the LEDs on the front side of the beauty device, there is a problem of disposition with the oscillator assembly located on the front side of the housing, a design problem of thickening the thickness, a light source rotation problem for irradiating the blade direction and the user's face direction, In particular, various problems such as difficulty of waterproof are encountered. It is an object of the present invention to solve such a problem.

On the other hand, the blade PCB of the vibrator assembly which generates the ultrasonic vibration consists of an epoxy resin and an oscillator mounted on the epoxy resin. The epoxy resin is used for insulation, but there is a problem that loss of vibrations generated in the vibrator due to the elasticity of the epoxy resin occurs, and also the thickness of the epoxy resin is increased to increase the total thickness. An object of the present invention is to solve such a problem effectively.

In realizing this goal, we set the following specific issues in more detail:

- Is it possible to solve the waterproofing problem by placing the LED light source at the rear end of the oscillator assembly in the housing.

- What kind of structure is possible by arranging a light guide plate on the front face of the LED light source so that the LED light can be irradiated simultaneously in the direction of the blade and the top face of the housing.

- What is the technological way to effectively guide the LED light received from the placed LGP toward the blade?

- There are ways to improve the waterproof efficiency and to prevent the loss of ultrasonic vibration.

According to an aspect of the present invention, there is provided a portable skin beauty device having a color therapy function using LEDs, the device comprising: a housing; A vibrator assembly received in the housing and generating vibration; A metal blade coupled to the vibrator assembly and exposed to the front of the housing; An LED light source installed in a wall between the vibrator assembly and an internal circuit arrangement area inside the housing for emitting LED light for color therapy in the direction of the exposed blade; And a vibrator assembly disposed on the upper portion of the vibrator assembly and physically separated from the vibrator assembly so as to pass the LED light forward and to guide the traveling direction of the LED light portion toward the upper surface of the housing, And a first light guide plate provided on the first light guide plate.

Further, the present invention may further include a second light guide plate coupled to a front end of the first light guide plate and guiding the LED light having passed through the first light guide plate toward the blade.

The light guide plate may further include a reflective sheet surrounding the lower surface and the side surface of the first light guide plate.

The reflective sheet may be formed of a rubber material for a sealing structure.

Wherein the vibrator assembly includes a metal PCB attached to an upper surface of the blade in the housing, the metal PCB comprising: an aluminum plate; An insulating layer of a thin plate disposed on the aluminum plate; And a vibrator disposed on the insulating layer.

The portable skin beauty device incorporating the color therapy function of the present invention can solve the waterproof problem of the LED light source by incorporating the LED light source inside the housing.

In addition, a first light guide plate V-CUTTING is disposed on the front surface of the LED light source so that the LED light can be irradiated simultaneously in the blade direction and the top surface direction of the housing.

Further, the second light guide plate may be disposed on the entire surface of the first light guide plate to effectively guide the LED light received from the first light guide plate toward the blade.

In addition, a reflection sheet made of a rubber material may be disposed on the back and side surfaces of the light guide plate in place of the reflection sheet of the light guide plate to improve the waterproof efficiency.

In addition, by replacing the blade PCB including the epoxy resin with the metal PCB, the thickness of the vibrator assembly can be reduced, and vibration loss due to the epoxy resin can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The terminology used in this application is used only to describe a specific embodiment and is not intended to limit the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise. In the present application, the terms "comprises" or "having" and the like are used to specify that there is a feature, a number, a step, an operation, an element, a component or a combination thereof described in the specification, But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a portable skin beauty device incorporating a color therapy function according to the present invention will be described in detail with reference to the accompanying drawings. And redundant explanations thereof will be omitted.

1 is a block diagram of a portable skin beauty device incorporating a color therapy function according to an embodiment of the present invention. 1, the present invention is a portable skin beauty device having a color therapy function using LEDs. The device includes a housing 100, a vibrator assembly, a blade 300, an LED light source 400, and a first light guide plate 500, .

The housing 100 surrounds the entire apparatus and protects the components contained therein. Inside the housing 100, two chambers may be physically separated from each other. These two chambers can be separated by the main wall 200 located at approximately the middle portion inside the housing.

The vibrator assembly of the first light guide plate 500 and a part of the blade 300 are coupled to the front side chamber of the housing separated by the second wall 200. The rear side chamber 900 of the housing is provided with a printed circuit board, Are accommodated. At this time, the LED light source 400 may be installed on the rear wall 200.

The secondary wall 200 separates the housing into the two chambers described above and prevents moisture from flowing into the rear chamber. That is, when a beauty device using an ultrasonic wave is used, water or cosmetic lotion is applied to the skin, and the blade is closely attached to the skin. In this case, water or lotion can permeate into the housing, The microcomputer, and the power source of the rear portion of the housing, which are very sensitive to the temperature and humidity, are protected from water and toilet water.

The power supply unit includes a battery made of a rechargeable lithium-polymer secondary battery. The power supply unit supplies power to the LED light source unit and the vibrator assembly. That is, in order for the LED light source unit to emit LED light, or for the oscillator assembly to operate, power must be supplied, and a predetermined cable connects the power source unit, the LED light source unit, and the oscillator assembly to each other, Thereby operating each device.

The internal circuit connects the power supply unit and the oscillator, boosts the DC voltage of the power supply unit to a voltage of a predetermined magnitude, and transmits the voltage to the oscillator assembly. The vibrator assembly converts the electrical energy transferred from the internal circuit into the vibration energy of the ultrasonic vibration. That is, power from the power source unit is transmitted to the vibrator of the vibrator assembly, and ultrasonic vibration occurs. When the ultrasonic vibrator physically vibrates, the vibration is transmitted to the user's skin via the blade. In addition, the microcomputer has a built-in control program for controlling the operation time and operation, and serves to output a preset resonance frequency for vibration of the ultrasonic vibrator.

The vibrator assembly is accommodated in a front chamber of the housing 100 and converts electrical energy transferred from the power supply unit and the internal circuit to generate ultrasonic vibration. The physical vibration due to the ultrasonic waves generated in the vibrator assembly is transmitted to the skin through the blades 300 coupled thereto. A specific configuration of the vibrator assembly will be described later.

The blade 300 has one end contacting the skin and the other end located inside the housing 100. That is, approximately half of the entire blades 300 are exposed to the outside of the housing 100, and the other half is coupled to the vibrator assembly inside the housing 100. At this time, the blade 300 is made of a metal material such as a stainless steel plate or a hard beating plate, and has a moderate bending elasticity.

A blade 300 holder 800 is formed at an approximately middle portion of the blade 300 so that the blade 300 is firmly fixed to the skin to prevent the blade 300 from being detached from the housing 100 .

The LED light source unit 400 is positioned on the inner wall of the housing 100. The LED light source unit 400 irradiates high-intensity LED light for color therapy, and irradiates the skin with LED light to promote skin metabolism, thereby promoting skin beauty. LED light has various effects depending on the color. Accordingly, the LED light source unit 400 may include a plurality of light sources. That is, it is possible to irradiate the skin with various light sources in accordance with the skin modifying effect.

By disposing the LED light source unit 400 according to the present invention on a wall located at a substantially middle portion inside the housing, it is possible to greatly reduce problems such as damage to the LED light source due to submergence that may occur during operation of the skin beauty apparatus. That is, when the blade is in close contact with the skin, water or lotion may be present on the skin. Water or cosmetic liquid may penetrate into the housing due to the vibration of the blade, It is preferable to be located far away.

If the LED light source unit 400 is disposed at the upper end of the blade 300 inside the housing 100, that is, between the exposed blade and the vehicle wall, problems arise in placement of the LED light source unit 400 with respect to the vibrator assembly located at the front portion of the housing 100, And a light source rotation problem for irradiating the direction of the blade 300 and the face of the user. However, the present invention does not cause such a problem.

The first light guide plate 500 is physically separated from the vibrator assembly inside the housing 100 and disposed on the vibrator assembly. The first light guide plate 500 serves to change the traveling direction of a part of the LED light source irradiated from the LED light source 400 toward the end of the blade 300. When the blade 300 is in contact with the face at an angle to exfoliate a portion of the face, the housing or body portion of the skin beauty device also faces the rest of the face. At this time, LED light is irradiated to the remaining part of the face to activate the skin metabolism of the irradiated part, thereby promoting skin beauty. That is, the direction of the LED light directed toward the end of the blade 300 exposed to irradiate the LED light on the face of the user when the skin cosmetic device faces the face of the user faces the upper surface of the housing 100, As shown in FIG.

At this time, the reflective sheet 700 may be formed on the lower surface and the side surface of the first light guide plate 500. The reflective sheet 700 is intended to prevent transmission of LED light to unnecessary places and to improve efficiency of LED light transmission to a desired place. That is, the reflective sheet 700 surrounds the lower portion and the side portion of the first light guide plate 500 so that the LED light can be concentrated and reflected on the upper portion of the first light guide plate 500.

Further, the reflective sheet 700 may be formed of a rubber material for a sealing structure. That is, by adopting the sealing sheet 700 of the sealing material in the housing 100 instead of the ordinary reflection sheet, it is possible to simultaneously obtain the waterproof property of the housing 100 and the reflection effect of the LED light.

2 is a view showing a traveling direction of the LED light in the first light guide plate 500 according to an embodiment of the present invention. As shown in FIG. 2, the first light guide plate 500 is formed with a plurality of V-cuts V to change the traveling direction of the LED light. 6 to 70% of the LED light irradiated from the LED light source unit 400 is changed in the direction of the top surface of the housing 100 and the remaining 3 to 40% of the LED light is transmitted to the blade 300 exposed to the outside of the housing 100, End direction and other directions.

3 is a view illustrating a second light guide plate 600 according to an embodiment of the present invention. The second light guide plate 600 according to the present invention is formed at the front end of the first light guide plate 500 so as to guide the above-described 3 to 40% LED light toward the exposed blade 300. The thickness of the second light guide plate 600 may be preferably equal to the thickness of the first light guide plate 500. The second light guide plate 600 includes a guide portion 610 for guiding the LED light transmitted from the first light guide plate 500 directly to the end of the exposed blade 300 and the guide portion 610 and the housing 100, The coupling portion 620 may be configured to be coupled to the coupling portion 620. FIG. 3, the shape of the coupling portion 620 of the light guide plate may be formed to match the inner shape of the housing 100, for coupling the second light guide plate 600 to the housing 100. As shown in FIG.

The second light guide plate 600 is formed at the front end of the first light guide plate 500 so that most of the 3 to 40% of the LED light that can be dispersed is collected and advanced toward the exposed blade 300. Therefore, when the blade 300 removes the skin horny by contact with the skin, it can promote the metabolism of the skin and improve the skin horny removing efficiency.

FIG. 4 is an exploded view of a conventional vibrator assembly and a blade, and FIG. 5 is a view illustrating a conventional vibrator assembly combined with a blade. In this vibrator assembly, a first amplification plate 10 made of aluminum or an aluminum alloy or its corresponding material is attached to the upper surface of the blade in the housing via an adhesive sheet, and a second amplification plate 20 made of the same material is provided on the opposite side, Respectively. These two amplifier plates may have different thicknesses from each other. The amplification plate acts to amplify the physical displacement of the ultrasonic transducer transversely by applying a physical displacement to the skin to be suitable physical physical displacement.

A PCB including an insulating layer is disposed on the upper surface of the first amplification plate 10. The PCB including the insulating layer includes an insulating layer and a vibration circuit mounted on the insulating layer.

The insulating layer 31 can prevent the high voltage of the vibrator from flowing to the skin through the blade 300. The insulating layer 31 is formed of a conventional insulating material, and may be formed of a hard epoxy resin or the like.

On the upper part of the vibration circuit 32, a vibrator composed of a ceramic piezoelectric element on the disk is attached again. Such a vibrator can be connected to a power line to receive power. The power supplied to the vibrator generates ultrasonic vibration, which is transmitted to the skin of the user through the blades.

However, the conventional insulating layer 31 of the conventional vibrator assembly absorbs vibration generated in the vibrator, thereby reducing vibrations transmitted to the blades, and the thickness of the insulating layer 31 is increased to increase the overall thickness.

In order to solve this problem, a metal PCB is used instead of the PCB 30 including the insulating layer in any embodiment of the present invention.

FIG. 6 is a view showing a PCB of a conventional vibrator assembly replaced with a metal PCB according to an embodiment of the present invention. FIG. 7 is a perspective view of a vibrator assembly including a metal PCB according to an embodiment of the present invention, And FIG. 8 is a side view showing the vibrator assembly and the blade coupled by FIG.

The metal PCB 50 according to the present invention is disposed on the upper surface of the blade inside the housing. At this time, the metal PCB 50 is formed such that a thin plate insulating layer 52 is disposed on a plate of aluminum or the like, which is a metal 51, and a vibration circuit 53 is disposed on the insulating layer. A vibrator T is disposed on the upper portion of the oscillation circuit 53. The vibrating circuit 53 and the vibrator T are connected to a power supply line and are supplied with power. At this time, the vibrator T directly generates ultrasonic vibration.

The insulating layer may be a T-PLUG. By applying the aluminum metal PCB according to the present invention to the oscillator (T) assembly, the function of the heat sink can be performed with a high thermal conductivity of aluminum.

In addition, in constructing the oscillator (T) assembly, by applying such a metal PCB in place of the PCB including the epoxy resin, the vibration loss caused by the elasticity of the conventional epoxy resin can be reduced. That is, the insulating layer is formed of a thin plate, aluminum is disposed under the insulating layer, and vibration generated in the vibrator T can be directly transmitted to the blade through aluminum.

Further, by using a thin insulating layer, it is possible to reduce the overall thickness of the oscillator (T) assembly. At this time, the insulating effect due to the very thin insulation layer may be reduced, but this decrease is insufficient.

The scope of protection of the present invention is not limited to the description and the expression of the embodiments explicitly described in the foregoing. It is again to be understood that the present invention is not limited by the modifications or substitutions that are obvious to those skilled in the art.
