Abstract
A massage device includes a housing, a driving unit and two massage units driven by the driving unit. Each massage unit includes a planetary gear disc assembled with a universal joint, an inner gear engaged with the planetary gear disc, and a massage disc assembly disposed on a top of the inner gear and driven by the universal joint. The driving unit drives the planet gear disc to rotate and the universal joint drives the massage disc assembly to rotate, thereby providing kneading massage. The inner gear has an incline top surface. When the planet gear disc drives the inner gear to rotate, the incline top surface makes the massage balls on the massage disc assembly to move up and down, thereby providing patting massage. Thus, the massage device can produce kneading and patting massage actions.
Claims7
A massage device with dual massage units comprising:
- a housing including an upper housing cover and a lower housing cover that define an inner housing space, the upper housing cover having two openings;
- a driving unit disposed in a driving unit casing, the driving unit casing received in the inner housing space;
- two massage units driven by the driving unit, mounted on a top of the driving unit casing and received in the inner housing space, tops of the massage units respectively located at the openings of the housing, each of the massage units comprising a planetary gear disc, a universal joint mounted on a top of the planetary gear disc, an inner gear engaged with and driven by the planetary gear disc, and a massage disc assembly disposed on a top of the inner gear and driven by the universal joint;
- and
- an electric controller mounted in the housing and comprising a controller circuit and at least one switch;
- wherein the driving unit drives the planetary gear discs to rotate, each massage disc assembly is driven to rotate by the universal joint and a plurality of massage members disposed on the top of each massage disc assembly are forced to spin, each inner gear includes an inclined surface at the top thereof, and each planetary gear disc drives the inner gear to rotate and thus the massage members reciprocate moving up and down.
