Abstract

Portable, electrically driven, handheld sonic personal skin/hair care device includes a housing and a drive assembly to which is coupled a treatment member. The treatment member may include active ingredients incorporated during manufacturing that safely resist and inhibit the growth of mold, mildew and bacteria. The drive assembly includes a stator assembly, armature assembly, mounting member attached to the housing, elongated pivot arm having a first end directly coupled to the armature assembly and a second end directly coupled to the mounting member, and mounting arm having first and second ends, the first end being directly coupled to the armature assembly and the second end being directly coupled to the treatment member such that the stator, when energized, causes oscillation of the armature in an arcuate manner about a pivot point located at the mounting member in turn causing the treatment member to oscillate relative to the housing.

Claims (7)

1. A personal care appliance, comprising:

a housing;

a sonic drive assembly provided in the housing, the sonic drive assembly including a stator assembly, an armature assembly adjacent the stator assembly, a mounting member attached to the housing, an elongated pivot arm having a first end directly coupled to the armature assembly and a second end directly coupled to the mounting member, and a mounting arm having a first end and a second end, the first end being directly coupled to the armature assembly, wherein the stator, when energized, is structured to cause the armature assembly to oscillate in an arcuate manner about a pivot point located at the mounting member; and

a workpiece member coupled to the armature assembly such that oscillation of the armature assembly causes the workpiece member to oscillate relative to the housing at a sonic frequency, wherein the workpiece member comprises one or more components made with an antimicrobial material that is both (i) safe for use on the skin, and (ii) resists and/or inhibits the growth of mold, mildew, fungus and/or bacteria.

2. The personal care appliance according to claim 1 , wherein the workpiece member comprises a brush head assembly having a plurality of bristles extending therefrom, wherein the bristles include the antimicrobial material as an additive thereto and/or are coated with the antimicrobial material.

3. The personal care appliance according to claim 1 , wherein the antimicrobial material includes silver ions.

4. The personal care appliance according to claim 1 , wherein the antimicrobial material includes essential plant oils and/or essential minerals.
