Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings showing embodiments of the present invention.

FIG. 1 is a perspective view of a portable skin care device according to an embodiment of the present invention, and FIG. 2 is a sectional view of the portable skin care device of FIG. 1. 3 is a block diagram of a portable skin care device according to an embodiment of the present invention. 1 to 3, a portable skin care device 100 according to an embodiment of the present invention includes a care unit C, a body unit B, a vibration generating unit 120, a thermoelectric element 110, .

The care unit C is coupled to the upper end side of the body part B to form the head side of the portable skin care device 100.

In the care unit (C), a plate surface (101) formed of a thermally conductive material and exposed to contact with the skin is formed. The exposed plate surface 101 is in direct contact with the skin of the human body and carries out care of the skin. The plate surface 101 has a predetermined area so that it can be used even in the three-dimensional shape of the face.

In the care unit C, the thermoelectric element 110 and the vibration generating unit 120 are formed. The thermoelectric element 110 is heated and cooled by receiving operating power and heating or cooling the plate surface 101. According to the embodiment of the present invention, the thermoelectric element 110 uses a Peltier element that can generate heat or absorb heat using the Peltier effect.

The thermoelectric element 110 is disposed on the rear side of the plate surface 101 and contacts the plate surface 101 to regulate the temperature of the plate surface 101 of the care unit C as heat or heat is absorbed. Since the plate surface 101 of the care unit C is formed of a thermally conductive material, the temperature can be quickly changed to a temperature formed through the thermoelectric element 110. [

Here, as the thermally conductive material of the plate surface 101, a metal material such as aluminum having high thermal conductivity may be used.

The vibration generating unit 120 is installed so as to be exposed at the center of the plate surface 101 of the care unit C. Then, the vibration generating unit 120 emits ultrasonic waves in the set band. When the care unit C is brought into contact with the skin in a state in which the vibration generating unit 120 is in operation, ultrasonic waves are emitted toward the skin and vibration is applied to the skin as the ultrasonic waves are emitted.

The vibration caused by the ultrasonic waves massage the skin and promote the metabolism, thereby contributing to the generation of waste cells and somatic cells, thereby forming a healthy skin.

In the embodiment of the present invention, since the thermoelectric element 110 and the vibration generating part 120 are formed together, the effect of skin care can be remarkably improved. The temperature of the skin is warmed up when the skin care is performed while the temperature on the side of the care unit C is raised through the thermoelectric element 110. [ At this time, the vibration by the ultrasonic wave is applied to improve the blood circulation of the skin, to maximize the generation of somatic cells, and to open the pores to induce the discharge of the waste accumulated in the skin.

In addition, when an appropriate amount of cosmetic material such as a moisturizer or a nutritive cream is applied to the skin, an effective skin can be managed by absorbing the beneficial nutrients of the cosmetic material to the skin's dermis layer with the opened pore.

 In addition, when the thermoelectric element 110 is controlled to be cooled when the skin care for a proper time is performed, the pores contract to absorb the beneficial nutrients to maintain the beneficial nutrients and have elastic skin do.

The body portion B is engaged with the lower end of the care portion C so as to be gripable. A PCB for controlling the operation of the portable skin care device 100 and a power supply unit 180 for supplying operating power are incorporated in the body part B. [

The power supply unit 180 is connected to a charging terminal exposed to the outside of the body portion B so as to be chargeable. The charging terminal is charged in a state of being mounted on a cradle (not shown).

On one side of the body part (B), an operation part (140) composed of a plurality of input buttons is provided so as to perform an operation according to a user's operation. The body part B is provided with a display part 150 for displaying a selection of an operation according to the operation part 140 or visually displaying an operation state.

The portable skin care device 100 according to the present invention may selectively transmit at least one of the thermoelectric element 110, the vibration generator 120, and the micro current generator based on the input through the operation unit 140 (Not shown).

The control unit 170 is provided with a CPU or microprocessor capable of processing and calculating inputs, and is mounted on the PCB to control the overall operation.

According to the above configuration, temperature control for skin care and vibration using ultrasonic waves can be formed by a simple operation, and portability is improved.

Referring to FIG. 4, the portable skin-ting device according to the embodiment of the present invention further includes a micro-current generating unit 130. The micro-current generating unit 130 is configured to be exposed to the plate surface 101 of the care unit C to generate micro current.

The fine current generating unit 130 includes a generator 132 and a plurality of electrodes 131. The generator 132 receives operating power through the constant current circuit configured on the PCB to generate a micro current. The micro current generated here is generated by adjusting the frequency of 100 Hz to 50 to 500 대역 so as to apply a stimulus that is beneficial to the skin.

The plurality of electrodes 131 are supplied with the minute current from the generator 132 and are formed so as to disperse and protrude on the plate surface 101 of the care unit C. In the embodiment of the present invention, two adjoining electrodes 131 are formed at regular intervals along the edge of the plate surface 101. The electrodes 131 are connected to the generator 132 to distribute the generated minute current.

The electric current output from each electrode 131 reaches the dermal layer of the skin and stimulates the biotissue, thus helping to activate the biological function.

In addition, among the nutritional ingredients contained in the cosmetic products for skin care, it is possible to penetrate the dermal layer of the skin by applying a minute current to the nutrients that are not directly absorbed by the skin, Collagen formation in the body, prevention of aging due to improvement of the function of living tissue, and improvement of elasticity.

Here, a current application method such as applying a current to each electrode 131 to give a stimulus to the skin or forming a stimulus by energizing in the biotissue of the skin with different polarities of the adjacent electrodes 131 Can be applied.

According to the embodiment of the present invention, the electrode 131 is formed on the plate surface 101 so as to protrude. When the portable skin care device 100 is used, the massage effect can be enhanced by the plurality of electrodes 131 that protrude into contact with the skin.

Since the side of the care unit C is rubbed on the skin while holding the portable skin care device 100, one side of the electrode 131 contacting the skin is preferably formed to have a hemispherical shape like a smooth surface .

According to the embodiment of the present invention, the care unit C can be configured to be rotated in the body part B in the portable skin care device 100. More specifically, the motor 160 is disposed inside the upper end of the body portion B and the care unit C is coupled to the motor 160 to rotate the care unit C in accordance with the rotation of the motor 160. [ By rotating the portable skin care device 100, the massage effect can be maximized simply by moving the portable skin care device 100 in contact with the skin.

Here, the control unit 170 can rotate the care unit C in one direction, but it is also possible to drive and rotate the motor 160 so that the motor 160 rotates in a constant rotation angle range.

5 is a view for explaining the operation and structure of the thermoelectric element. Referring to FIG. 5, the portable skin care device 100 according to the embodiment of the present invention may further include a limit switch. The limit switch limits the maximum temperature of the thermoelectric element 110 to a predetermined temperature.

The meaning of limiting the temperature here means to control not to exceed the maximum temperature in accordance with the safety problem and to keep the heat or heat absorbed by the thermoelectric element 110 at a constant level.

 The portable skin care device 100 according to the embodiment of the present invention is designed to operate in various operation modes. The controller 170 refers to the storage unit (not shown) to operate in the set operation mode and operates the configuration specified in the operation mode selected by the user.

Here, the operation mode may include a cold-care mode, a warm-care mode, an ultrasonic-care mode, a microcurrent-care mode, and an absorption mode.

The cold-care mode and the warm-care mode are modes in which the skin is controlled in a state in which the temperature of the plate surface 101 of the care unit C is adjusted by utilizing the endothermic reaction and the exothermic reaction of the thermoelectric element 110, An ultrasonic wave is generated by using a vibration generator, and a microcurrent care mode is an operation mode in which micro current is applied to the skin through a micro current generator, and each operation mode is performed independently.

The absorption mode is a skin care operation that optimizes the skin absorption of the cosmetic material applied to the skin by using a combination of the cold care mode, the warm care mode, the ultrasonic care mode and the microcurrent care mode.

In this operation mode, the output level, that is, the degree of the temperature, the intensity of the microcurrent, and the intensity of the ultrasonic wave, for example, are divided into a plurality of phases such as an upper, middle, and lower levels and the duration of the operation can be set.

Depending on the condition of skin such as dry skin, neutral skin, oily skin, complex skin, etc., it may be provided with appropriate duration and strength of care.

Hereinafter, the operation of the portable skin care device 100 according to an embodiment of the present invention will be described with reference to FIG.

6 is a view illustrating an operation process of the portable skin care device 100 according to an embodiment of the present invention. 6 illustrates an operation in a state in which the operation mode is the absorption mode.

More specifically, when the power is turned on by the user (S610), the operation mode is selected (S620). Here, the user selects the operation mode using the operation unit 140 and the display unit 150. The operation mode may be any one of the above-described cold-care mode, warm-care mode, ultrasound care mode, microcurrent care mode, And is displayed on the display unit 150 to select one operation mode. The user selects the operation mode using the operation unit 140. [

The selection of the operation mode includes a care intensity selection (S621) for adjusting the output intensity, a duration selection (S622) for selecting a continuous operation or an operation for a predetermined time, an operation programmed to perform a care operation according to the type of skin A skin condition selection step S623 for selecting a skin condition.

 In the absorption mode, in order to optimize the skin absorption of the cosmetic material applied to the skin, the controller 170 controls the thermoelectric element 110 to heat the thermoelectric element 110 to a predetermined temperature (S630). At this time, the control unit 170 compares the temperature of the thermoelectric element 110 with the set temperature (S640) so that the plate surface 101 of the care unit C can have a predetermined temperature according to the thermoelectric element 110, Thereby controlling the heat generation of the thermoelectric element 110 to reach the temperature.

When the set temperature is reached, the controller 170 activates the micro-current generator and the vibration generator (S650). At this time, the heat generation of the thermoelectric element 110 is maintained.

The control unit 170 confirms that the duration time corresponding to the duration time or the skin condition selection S623 entered during the care duration selection step S622 is reached and if the duration time elapses at step S660, The operation of the current generator and the vibration generator is stopped (S670). In the process up to this point, the thermoelectric element 110 exothermically reacts, so that blood vessels and pores of the skin in contact with the care unit C are expanded.

In this state, the control unit 170 controls the thermoelectric element 110 to perform an endothermic reaction (S680). Likewise, in the endothermic reaction of the thermoelectric element 110, it is confirmed whether the set temperature is reached (S690), and the heat absorbing control of the thermoelectric element 110 is terminated (S700).

When the thermoelectric element 110 undergoes an endothermic reaction, the plate surface 101 of the care unit C is cooled and a shrinking reaction occurs in the skin contacting the plate surface 101 of the care unit C.

That is, the control unit 170 controls the thermoelectric element 110 to cool the skin before the end of the skin care using the vibration generator 120 or the micro-current generator in the absorption mode to induce the skin contraction reaction .
