Title:
The brush head for an electric skin brush apparatus
Document Type and Number:
Japanese Patent JP5980820
Kind Code:
B2
Abstract:
The brushhead is used in a power skin brush appliance which includes a drive system having a single drive member. The brushhead includes a base assembly mountable to the drive system with an optional outer annular fixed portion and an inner portion which in operation oscillates back and forth at a selected sonic frequency through a selected angle in response to action of the drive system. Mounted on the outer portion is a first group of filament tufts. Mounted on the oscillating portion are three concentric groups of filament tufts. Each oscillating group of filament tufts includes two annular rings of filament tufts. The filament tufts in the oscillating filament tuft groups have a selected physical characteristic which in one embodiment is diameter, which differs between the respective oscillating filament tuft groups sufficiently to produce a differential stiffness between the filaments thereof to in turn produce an out of phase motion of the tips of the filaments between the three oscillating filament tuft groups.
