Abstract:
An apparatus for washing skin using a brushless electric motor and a spring is provided. The apparatus includes a case; an operation unit installed outside the case to generate a switching signal to allow the apparatus fco be powered on or off and the brushless electric motor to be rotated forward and reward in units of a predetermined angle; a power supply unit installed at one and inside the case; the brushless electric motor installed inside the case to be operated foy power applied from the power supply unit according to the switching signal from the operation unit, such that the brushless electric motor is rotated in units of the predetermined angle; a control unit to output an electric signal in order to control the forward and reward rotation of the brushless power at the predetermined angle according to the switching signal; a face-washing brush fitted with a shaft of the brushless electric motor to be rotated forward and reverse as the brushless electric motor is operated; a holder installed to the shaft of the brushless electric motor and including vertical and horizontal panels bent in a L-shape, wherein the holder is rotated forward and reverse as the brushless electric motor is rotated forward and reverse; a spring including one side coupled to the horizontal panel of the holder and an opposite side coupled to a support, wherein the spring moves along the support to generate a torque toward an original position by an elastic property as the holder moves upward and downward in a vertical direction; and the support to support the opposite side of the spring.
