Advantageous Effects

According to the embodiment of the present invention, the cleaning and absorption promotion of the cosmetics may be realized through one cosmetic device to improve the convenience of use and realize compactification and easy portability during the outdoor activates.

In addition, the one surface of the cosmetic device may have the absorption-promoting function, and the other surface of the cosmetic device may have the cleaning function, and thus, both the surfaces of the cosmetic device may be used.

In addition, in the state in which the user's hand touches the iontophoresis electrode adjacent to the brush unit, the absorption-promoting head may approach the user's face to improve the convenience in use.

In addition, the penetration of the moisture into the case space may be minimized to improve the reliability.

In addition, there may be advantage in that the upper portion of the brush unit is easy to enter the local areas such as next to the nose or next to the eyes, and thus, the fine cleaning is easy.

In addition, since the brush unit covers the portion of the iontophoresis electrode outside the case, the separate cover member for covering the iontophoresis electrode may be unnecessary, and the number of components may be minimized.

In addition, the inner head sealing member may seal the gap between the ultrasonic head and the case.

In addition, since the iontophoresis electrode is connected to the sub PCB by the spring, the connection state of the iontophoresis electrode may be maintained in high reliability.

The sub PCB 84 may be connected to the main PCB 82 as illustrated in FIG. 8. The sub PC unit 84 may be connected to the main PCB 82 through a separate cable or a board to board connector.

The sub PCB 84 may be an electrode PCB for electrically connecting the iontophoresis electrode 5.

The cosmetic device may include a spring 86.

The spring 86 may be disposed between the sub PCB 84 and the iontophoresis electrode 5.

The spring 86 may be made of a conductor and may electrically connect the iontophoresis electrode 5 to the sub PCB 84.

An example of spring 84 may be a coil spring.

A contact body 58 that is in contact with the spring 84 may be disposed on the iontophoresis electrode 5. The contact body 58 may be provided to protrude from the hidden body 52 toward the sub PCB 84.

An opening through which the contact body 58 passes may be defined in the second side case 16. An electrode sealing member 59 (see FIG. 8) may be disposed on the second side case 16 to seal a gap between the second side case 16 and the contact body 58. The electrode sealing member 59 may minimize moisture from being penetrated between the second side case 16 and the contact body 58.

An example of the electrode sealing member 59 may be a waterproof O-ring disposed between an outer circumference of the contact body and the second side case 16.

An example of using the cosmetic device is for allowing the user to perform the cleansing by using the brush unit 4 and promote the absorption of the cosmetics, etc. by using the absorption-promoting head 2.

After inputting power through the power input unit 11a, the user may select the cleansing mode through the mode input unit 11b, and when selecting the cleansing mode, the controller 8 may turn on the vibration motor 6 and the ultrasonic vibrator 34.

The user may place the brush unit 4 on the user's skin while wrapping the absorption-promoting head 2 by using the his/her hand, the inner head 33 may transmit the ultrasonic waves and the vibration to the user's skin, and the brush unit 4 may cleanse the user's skin while vibrating.

When the cleaning is completed in the cleaning mode as described above, the user may select the absorption-promoting mode through the mode input unit 11b, and the controller 8 may turn on the head ultrasonic vibrator 9 when selecting the absorption-promoting mode to apply the current to the absorption-promoting head 2 and the iontophoresis electrode 5.

After applying the cosmetics to the skin, the user may be in contact with the iontophoresis electrode 5 while wrapping the brush unit 4 through the his/her hand and may place the absorption-promoting head 2 on the user's skin.

The absorption-promoting head 2 and the iontophoresis electrode 5 may be electrically connected by the user, and the ions may be generated from the absorption-promoting head 2, and then, the ions may push the electric charges in the cosmetics into the skin so that the absorption of the cosmetics into the skin is promoted.

The above-disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments, which fall within the true spirit and scope of the present invention.

Thus, the embodiment of the present invention is to be considered illustrative, and not restrictive, and the technical spirit of the present invention is not limited to the foregoing embodiment.

Therefore, the scope of the present invention is defined not by the detailed description of the invention but by the appended claims, and all differences within the scope will be construed as being included in the present invention.
