FACE WASHING DEVICE HAVING BRUSH STRUCTURE IN WHICH INTERNAL BRUSH IS LAID ON EXTERNAL BRUSH

WIPO Patent Application WO/2015/126108

A1

The present invention relates to a face washing device having a brush structure in which an internal brush is laid on an external brush and, more specifically, to a face washing device having a brush structure in which an internal brush is laid on an external brush, the brushes being divided into external brushes and internal brushes, wherein the external brush is mounted in a mounting space of a front side body of the face washing device, and the internal brush is linked with a driving motor and is laid on the upper section of the external brush, so that when the brushes are mounted, the external brush is first mounted and then the internal brush is mounted, but when the brushes are detached, if only the external brush is removed, the internal brush is detached together and accordingly the mounting or detachment of the brushes is easy. In addition, the present invention relates to a face washing device having a brush structure in which an internal brush is laid on an external brush, wherein the external brush is mounted in a mounting space of a first side body, and the internal brush is coupled with a driving motor and thereby the external brush and the internal brush do not affect each other, so that when the internal brush washes skin while being vibrated by the driving motor, the external brush fixed in the mounting space of the front side body prevents water from splashing in all directions by means of a centrifugal force caused by the rotation of the internal brush, and the skin can be washed by being scrubbed manually by means of the external brush. The present invention comprises: a main body (10) consisting of a front side body (11) having a mounting space (12) formed therein, and a rear side body (15); a driving motor (20) which is mounted on the inside of the main body (10) and rotates clockwise or counterclockwise; an operation control part (30) for controlling the operation of the driving motor (20); a power supply part (40) for supplying power to the operation control part (30); a power transfer member (50) which is positioned at the mounting space (12) of the main body (10) and is coupled with the driving motor (20); an external brush (60) which is mounted in the mounting space (12) of the main body (10) and has a hollow section (61) formed in the center thereof; and an internal brush (70) which passes through the hollow section (61) of the external brush (60) and is coupled to the power transfer member (50), wherein on the inner circumferential surface of the hollow section (61) of the external brush (60), an annular rim protrusion (62) is formed and thus the internal brush (70) is laid on the annular rim protrusion (62) when being coupled to the power transfer member (50). In addition, the driving motor (20) of the present invention is characterized by having a motor shaft (21) formed at one side thereof, the motor shaft (21) being coupled with the power transfer member (50) by passing through a through hole (14) formed in the mounting space (12) of the main body (10). In addition, the power supply part (40) of the present invention is characterized by consisting of a battery (41) and a power button (42). In addition, the external brush (60) of the present invention is characterized by having an uneven section (63) formed on the edge thereof. In addition, the external brush (60) of the present invention is characterized by having a coupling groove (64) formed on the outer circumferential surface of the side surface thereof, the coupling groove (64) being coupled with a coupling protrusion (13) formed in the mounting space (12) of the main body (10). In addition, the internal brush (70) of the present invention is characterized by having a fastening rib (71) formed at the lower side thereof, the fastening rib (71) being coupled with the power transfer member (50) wherein the power transfer member (50) has a polygonal edge (51) formed thereon.
