Patent ID: 8137363

Claim:
An electrical dermabrasion device comprising: a main body provided with a hollow portion; an abrasion unit connected to the main body, for a dermabrasion; a driving unit including a motor incorporated in a hollow portion of the main body, for rotating the abrasion unit, wherein the abrasion unit includes a generally planar rotary plate and a generally planar abrasion plate removably attached to a front surface portion of the rotary plate, the abrasion plate having a generally planar abrading surface which is generally perpendicular to an axis of rotation of the abrasion plate, the abrading surface is provided with a plurality of suction holes for suctioning exfoliated skin pieces resulting from the dermabrasion, the rotary plate including a plurality of discrete radially extending partitions forming skin piece storages for collecting therein the exfoliated skin pieces suctioned through the suction holes of the abrasion plate, the partitions including ribs and the storages include grooves formed between the ribs, the abrasion unit further including a connection frame removably securable to the main body, the connection frame accommodating therein the rotary plate and the abrasion plate; and a guard ring installed at an upper portion of the main body to prevent a dispersion of the exfoliated skin pieces, the guard ring having a first side and a second side opposite the first side with the abrasion plate disposed between the first and second side, wherein a height of the guard ring varies from the first side to the second side, such that the first side is higher than the second side, and wherein the guard ring has a top surface defining an upper extent of the guard ring, and the top surface at the first side of the guard ring is disposed above the abrading surface.
