That is, the light emitted from the light source 140 may be emitted through the transparent cover 113 disposed in the hollow portion of the seating surface 114 in a relatively narrow range than the irradiation angle of the light source itself.

Accordingly, even if the light source 140 is operated in the state of being close to the user's skin, particularly the face, the light generated from the light source 140 is emitted in a narrow range on the side of the skin requiring care, thereby preventing light from entering the user's eyes .

At this time, the cosmetic device 100 according to the present invention illuminates the light source 140 only when the distance between the light source 140 and the skin is within a predetermined range, and the distance between the light source 140 and the skin is preset The light source 140 may be turned off.

This prevents the user's eyes from being directly exposed to the light emitted from the light source 140 when the light-transmissive cover 113 is inadvertently directed toward the user's eyes during the use process, This is to prevent it.

For this, at least one proximity sensor 152 is provided on the circuit board 142 on which the light source 140 is mounted, thereby detecting the distance between the light source 140 and the skin and lighting / Can be controlled.

Here, the proximity sensors 152 may be provided in plurality, or may be disposed between adjacent light sources 140, or may be disposed outside the light source 140 disposed at the outermost position.

In addition, the light source 140 may be used only when both the contact electrodes 112 are in contact with the user's skin and the distance between the light source 140 and the skin is within a predetermined range Initial lighting can be done.

This is because even if the distance between the light source 140 and the skin is within a predetermined range in a process of moving to a body part to be cared by a user, So that the initial lighting can be performed in a state where it is finally moved to the precise position desired for the care. This makes it possible to prevent sudden operation regardless of the intention of the user.

 The pair of contact electrodes 112 is used to increase the skin permeation of the ionic drug by changing the electric environment of the skin by generating a potential difference on the user's skin when the power is applied.

That is, the pair of contact electrodes 112 are used to realize the function of a known iontophoresis. By applying a DC current to a user's body using a power source supplied through a battery 154, And the pair of contact electrodes 112 constitute a closed circuit, ion movement occurs.

For example, when an ionic drug is applied to the skin of a user and a direct current is applied to the pair of contact electrodes 112 to ionize the ionic drug to the skin of the user, the ionic drug easily passes through the skin mucosa, The effect of iontophoresis penetrating into the internal tissues occurs.

The pair of contact electrodes 112 are disposed on the same surface of the body 111 as described above. That is, the skin-care device 100 according to the present invention is characterized in that a pair of contact electrodes 112 for the iontophoresis function are bi-polarly fixed to the seating surface 114, ) Method.

Accordingly, when the upper portion of the case 110 is brought into contact with the body part in a state where the user applies an ionic drug to the body part to be cared, a pair of contact electrodes Lt; RTI ID = 0.0 > 112 < / RTI > Therefore, even if the user changes the gripping position of the case 110 during use, the pair of contact electrodes 112 are kept in contact with the skin at all times, so that the iontophoresis function can be used smoothly.

The light-transmissible cover 113 is integrally formed with the body 111 and is disposed on the front side of the light source 140 to protect the light source 140 from the external environment. When the light source 140 is turned on, To protect the user's eyes from the light emitted to the user. In addition, the light-transmissible cover 113 may perform a function of increasing the diffusibility of light generated in the light source 140 so that uniform light can be emitted to the outside.

The light transmitting cover 113 may be formed to have a predetermined transmittance so as to reduce the intensity of light emitted from the light source 140 and emitted to the outside, Lt; / RTI >

For example, the light-transmitting cover 113 may have a transmittance of 70 to 90%, and preferably a light-diffusing PC having a transmittance of 70 to 90% may be used. Here, the transmittance of the transparent cover 113 is 70 to 90%. However, the transmittance is not limited thereto, and it is possible to appropriately adjust the transmittance of the transparent cover 113 if it can protect the user's eyes and increase the light diffusibility.

Also, since the body 111 includes the light blocking material, the light emitted from the light source 140 can be prevented from being emitted to the outside through the body 111. The light shielding material may be a known black resin or a black pigment, but not limited thereto, and may be any material that can prevent light leakage by blocking light. Examples of the light shielding material include chromium (Cr), gold (Au) , Silver (Ag), copper (Cu), and platinum (Pt), so that the electromagnetic wave shielding property and the light shielding effect can be realized at the same time.

The skin care apparatus 100 according to the present invention may be configured to change the light emitting mode of the light source, turn on / off the power source, turn on / off the light source, and information obtained by the proximity sensor 152 And a control unit for controlling the overall driving. The control unit may be implemented in the form of a chipset mounted on one surface of the main circuit board 155. The control unit may be operable in accordance with the distance between the skin and the light source 140 obtained through the proximity sensor 152, And a look-up table capable of adjusting the output intensity or appropriately adjusting the magnitude of the direct current applied to the contact electrode 112 can be stored.

In addition, the skin care apparatus 100 according to the present invention may be provided with a notification unit linked to the operation of the button 162. The notification unit allows the user to easily recognize the operation of the button 162 by the user. For example, the notification unit may be vibration means 153 electrically connected to the circuit board 142, and may be an audio output means (not shown) such as a speaker for outputting sound to the outside. Here, the vibration means 153 may be a vibration motor or a vibration sensor.

That is, when the user presses the button 162, the controller recognizes the operation of the button 162 through the signal transmitted from the circuit board 164 disposed at the rear side of the button 162, The vibration is generated through the means 153 for a predetermined time or the sound is output to the outside. Accordingly, the user can easily change the desired mode by easily recognizing the on / off of the power source and the change of the light emission mode of the light source through the operation of the button 162. [

Here, the output pattern of the notification unit may be output in a different pattern for each mode. For example, in the case of the vibration pattern generated by the vibration means 153, at least one of the intensity of vibration and the duration of vibration at the time of selection or change to the first light emitting mode, the second light emitting mode, It is possible to output the sound in a different pattern, and when sound is outputted through the speaker, a sound unique to each mode can be outputted to the outside.
