Abstract
In one aspect of the present invention, a massage device includes a base cover, a carriage movably engaged with the base cover, a kneading assembly mounted on the carriage, and an up-down movement assembly that allows the carriage to move up and down along a longitudinal axis of the carriage. The kneading assembly includes a motor, a worm coaxially coupled to the motor, a first worm wheel meshing with the worm, and a cylindrical rod coaxially coupled to the first worm wheel. The cylindrical rod has a first end and an opposite, second end. The kneading assembly further includes a pair of eccentric wheels, each of which is coaxially coupled to the cylindrical rod at a respective end thereof. Mounted on each disk is a wheel-type massage head with a plurality of protrusions thereon. In operation, the motor drives, in sequence, the worm, the first worm wheel, the cylindrical rod, and the pair of massage heads, thereby providing rolling-like kneading effects to a part of a body under massage.
