Abstract
A self-cleaning dental mirror tool. The dental mirror tool includes a handle portion, a neck portion, a power pack, and a head portion. The handle portion holds the power pack. The power pack is self-contained within a housing. This power pack comprises a motor, a control switch, and one or more batteries. The power pack is removable from the handle portion. An adaptor is affixed to the end of the drive shaft of the motor. The adaptor engages a pinion having a circular bevel gear. The circular bevel gear engages an annular gearing ring on a rotor assembly having a rotor shaft and a disc to which a mirror is affixed. The mirror may be in the form of a detachable sticker with a reflective surface. In use, the mirror rotates at high speed. This high-speed rotation expels water and debris from the surface of the mirror.
Claims16
A dental mirror tool comprising:
- a handle portion;
- a power pack comprising:
- a motor having a drive shaft affixed to an adaptor;
- a control switch;
- and
- at least one battery,
- a neck portion;
- a head portion, said head portion comprising:
- a housing;
- a rotor assembly comprising:
- a rotor comprising a rotor shaft, an annular gearing ring, and a disc, wherein said rotor shaft, said annular gearing ring, and said disc are fabricated as a single piece, and wherein said annular gearing ring is integrated into an underside of said disc;
- and
- a C-clip to retain said rotor shaft in said housing;
- and
- a pinion comprising:
- a pinion shaft having a distal end that is directly connected to a circular bevel gear;
- and
- a proximal end having a receiving slot,
- wherein said distal end and said proximal end are on opposing ends of said pinion shaft;
- a mirror, and
- a drive mechanism for rotating said disc, the drive mechanism consisting of:
- said circular bevel gear having a first set of teeth;
- and said annular gearing ring having a second set of teeth, wherein said first set of teeth is meshed with said second set of teeth,
- wherein when said drive shaft rotates as said motor operates, said pinion shaft rotates to thereby rotate said circular bevel gear and to thereby rotate said annular gearing ring and said disc by way of enmeshing between said first set of teeth and said second set of teeth,
- wherein said power pack is removably inserted in said handle portion;
- wherein when said power pack is inserted in said handle portion, said adaptor is received by said receiving slot;
- wherein said housing houses said rotor assembly and wherein said C-clip retains said rotor assembly within said housing,
- wherein said disc comprises a first side and a second side,
- wherein said rotor shaft projects from said second side such that said rotor shaft is perpendicular to said disc,
- wherein said adaptor is received by said receiving slot to thereby operatively couple said motor to said disc,
- wherein said mirror is affixed to said first side,
- wherein said neck portion joins said handle portion to said head portion,
- wherein said mirror comprises a detachable sticker, said detachable sticker comprising:
- a reflective surface;
- and
- an adhesive surface,
- wherein said reflective surface and said adhesive surface are on opposite sides of said sticker, and wherein said adhesive surface detachably affixes said mirror to said disc, such that said mirror is replaceable by a similar detachable sticker.
