Abstract
A rotatable electric brush device is provided which may utilize a handle portion disposed at a proximal end thereof. The handle portion may have a hollow handle body having a handle exterior surface defining a handle cavity within the handle body. The handle cavity may have a portion of a driveshaft disposed therein. The rotatable electric brush device may also utilize a brush portion disposed at a distal end of the rotatable electric brush device such that the brush portion may have a hollow brush body having a brush exterior surface defining a brush cavity within the brush body. The brush cavity may utilize a shaft body and a portion of a secondary handle disposed therein and the brush exterior surface may have a plurality of bristles extending outward therefrom.
Claims17
A rotatable electric brush device, comprising:
- a handle portion disposed at a proximal end of the rotatable electric brush device, wherein:
- the handle portion comprises a hollow handle body having a handle exterior surface defining a handle cavity within the handle body,
- the handle cavity comprises a portion of a driveshaft disposed therein, wherein the driveshaft is coupled to an electronic drive unit at a proximal end of the driveshaft,
- the electronic drive unit is electronically coupled to a drive actuator that is not covered by the handle exterior surface,
- a distal end of the driveshaft is not contained within the handle cavity and is not covered by the handle exterior surface, and
- the distal end of the driveshaft comprises an inner sheath partially defining an engagement cavity;
- and
- a brush portion disposed at a distal end of the rotatable electric brush device, wherein:
- the brush portion comprises a hollow brush body having a brush exterior surface defining a brush cavity within the brush body,
- the brush cavity comprises a shaft body and a portion of a secondary handle disposed therein,
- the secondary handle comprises a hollow elongate coupling rod at a proximal end of the secondary handle and a gripping structure at a distal end of the secondary handle,
- the hollow elongate coupling rod comprises a magnetic disc disposed therein,
- the magnetic disc comprises a first degree of freedom of movement axially along the length of the hollow elongate coupling rod, and
- the brush exterior surface comprises a plurality of elongate bristle members extending outward therefrom.
