US Patent:

7157816, Jan 2, 2007

Filed:

Jun 22, 2004

Appl. No.:

10/873564

Assignee:

Pacific Bioscience Laboratories, Inc. - Bellevue WA

International Classification:

H02K 33/00

US Classification:

310 36, 310 38

Abstract:

The motor assembly which produces an oscillating action for a personal care device includes a horizontally positioned U-shaped stator portion, and an armature portion which includes a torsion spring shaft which is anchored at one end thereof. The armature portion also includes a U-shaped magnet mounting member which is fixed near the upper end of the spring shaft, the U-shaped member including two opposing legs which extend along a substantial part of the length of the spring shaft, away therefrom. At the tips of each leg are magnet assemblies, which interact with the stator portion in alternating torsion, to produce a back-and-forth oscillation of the armature and a brushhead or other workpiece attached thereto.

Assignee:

Pacific Bioscience Laboratories, Inc. - Bellevue WA

International Classification:

A61B 17/50

US Classification:

606131, 604289, 604313

Abstract:

The apparatus includes at least two skin-contacting elements, the elements having narrow end faces and a mounting assembly for holding the elements closely adjacent to each other. A driving assembly reciprocally moves one element relative to the adjacent element(s) at a frequency that produces an action on the pores of the skin to loosen sebaceous plugs present in the pores, by permitting their ready removal from the skin.

International Classification:

A46B 13/02

US Classification:

15 28, 15 221, 15 211, 15 971

Abstract:

The brushhead attachment system includes a hub member which is secured to a drive shaft of a personal care appliance for oscillating action. The hub member includes a number of spaced locking elements in the form of protrusions around the periphery thereof. An annular outer brushhead portion with a first group of bristles includes a plurality of spaced grooves in the outer surface thereof which mate with extending pins in the body of the appliance for insertion and removal of the outer brushhead portion. An inner brushhead portion is configured to fit within the annular opening of the outer brushhead portion and includes a plurality of depending legs which mate with the protrusions on the drive member for resulting oscillating action of the inner brushhead portion when the drive member oscillates, at least some of the legs having latch elements which fit onto an interior lip of the outer brushhead portion in such a manner that the inner and outer brushhead portions may be installed and removed as a unit, while permitting the inner brushhead portion to be freely rotatable relative to the outer brushhead portion.
