Abstract
A cleansing device for mammalian skin includes a cleansing head having a plurality of elastomeric cleansing features extending away from the first surface and having an aspect ratio of about 1:5 to 10:1. The cleansing head is attached to a handle adapted to apply oscillating movement to one or more cleansing head sections to provide a total displacement per oscillation of about 2 mm to 8 mm at a frequency of about 5 Hz to 30 Hz.
Claims20
A cleansing device comprising
- a handle;
- a motor disposed within the handle and comprising a drive shaft rotatable about a drive shaft axis;
- a first gear coupled to the drive shaft such that it rotates along with the drive shaft;
- an engagement member centered on the drive shaft axis and operatively coupled to the first gear such that rotation of the first gear results in arcuate oscillation of the engagement member about the drive shaft axis;
- a planetary gear assembly operatively driven by the engagement member and comprising:
- a sun gear operatively coupled to a first portion of a cleansing head to cause the first portion to move in an arc in a first direction responsive to the arcuate oscillation of the engagement member;
- and
- a ring gear operatively coupled to the sun gear via a plurality of planetary gears of the planetary gear assembly, and operatively coupled to a second portion of the cleansing head to cause the second portion of the cleansing head to move in an arc in a second direction, opposite the first direction, while the first portion moves in an arc in the first direction.
