Patent ID: 7077816

Claim:
A kneading massager comprising: a speed reduction gear unit; a direct current (DC) driving motor; a massage block, wherein said speed reduction gear unit is in mesh with a transmission gear at its bottom for inputting a mechanical power to said unit; several output shafts are emerged out of a top surface of said speed reduction gear unit, wherein each output shaft is fitted with a metal washer disposed on the top surface of said speed reduction gear unit, said DC driving motor is coupled to a worm gear having a motor output shaft, said DC driving motor is disposed beneath said speed reduction gear unit such that the said worm gear can be in mesh with said transmission gear at the bottom of said speed reduction gear unit; and said massage block further includes a main body and a bottom cover, said main body has a hole at its bottom, wherein said bottom cover is provided with several confinement holes around its edge, and each confinement hole has a ball in it, said bottom cover is engaged to the bottom of said main body with its center hole aligned to the bottom hole of said main body and a metal pad is sandwiched therebetween such that said balls arrayed around the edge of said bottom cover are in contact with said metal pad, said balls are easily rotatable by mating with said metal washers disposed on the top surface of said speed reduction gear unit and thus facilitate motion of said massage block when said massage block is engaged with the output shaft of said speed reduction gear unit; whereby when said DC driving motor rotates, the mechanical power is transmitted to said massage block via said worm gear coupled to said motor output shaft, to said transmission gear, then to said speed reduction gear unit such that said massage block is driven by the output shaft of said speed reduction gear unit to perform inwardly or outwardly kneading motion like human fingers.
