Abstract

A device for face for forming a relatively high potential difference between power terminals of different polarities without a voltage booster circuit to make a lot of current flow through human skin such that function of iontophoresis may be remarkably improved and simultaneously for driving electrically-driven modules of a mask individually without an external power supply to stimulate entirely or partially. The massage device for face includes a mask including an accommodation formed therein and a terminal exposing hole of a terminal for making current to human skin, and at least one electrically-driven module accommodated in the accommodation of the mask, exposing two terminals of different polarities to the outside through the terminal exposing hole, a driving unit having a rotary shaft and a coil wrapping the rotary shaft, and increasing a potential difference between the two terminals using an induced electromotive force of the coil.

First claim

What is claimed is:

1. A massage device for face comprising:
a mask comprising:
an accommodation formed therein;
a terminal exposing hole of a terminal; and
a first mask and a second mask, wherein a circumference of the first mask and a circumference of the second mask are fixed to each other to form the accommodation; and

at least one electrically-driven module, accommodated in the accommodation of the mask, comprising:
a driving unit having a rotary shaft and a coil wrapping the rotary shaft; and
a battery,

wherein the electrically-driven module exposes two terminals of different polarities to an outside of the mask through the terminal exposing hole and increases a potential difference between the two terminals using an induced electromotive force of the coil,
wherein at least one of the first mask and the second mask comprises at least one of an insertion hole for inserting and withdrawing the electrically-driven module, and
wherein an induced electromotive force processor comprises an input end connected between a driving switch and the driving unit in parallel and making electric energy generated from the coil around the rotary shaft when the driving unit is idle by the switching off of the driving switch flow to an output end of the driving unit,
wherein a minus (−) power terminal of the base is electrically connected to the output end of the driving unit such that a current flows when the driving unit is idle by the switching off of the driving switch flow to an output end of the driving unit, and
wherein the current is configured to flow between the power terminals through the user's skin.

2. The massage device for face as claimed in claim 1 , wherein the electrically-driven module further comprises:
a base comprising power terminals of different polarities formed on a side to drive a vibrator and are configured to be connected to each other through the user's skin as a conductor;
the vibrator installed on at least one side of the base;
the driving unit installed in the base comprising the rotary shaft for providing a driving force to the vibrator and the coil interposing the rotary shaft therein;
the driving switch installed at a power input end of the driving unit to switch on/off a power supply of the driving unit; and
a controller controlling the switching on/off of the driving switch to control operating state of the driving unit and vibration state of the vibrator according to the operation of the driving unit.

3. The massage device for face as claimed in claim 2 , wherein the controller controls the driving switch to switch on/off by a preset time interval in pulse width modulation (PWM).

4. The massage device for face as claimed in claim 1 , further comprising a wearing unit enabling a user to wear the mask on his/her head.
