Massager with single rod eccentric drive mechanism to provide synchronize wave oscillation treatment

A massager having a single rod eccentric drive mechanism to provide synchronize wave oscillation treatment, the massager comprising,

• a driving means includes at least one motor to provide working force in the massager;
• at least one gear is attached to a corresponding motor shaft of the at least one motor, at least one timing pulley to guide the corresponding motor shaft in the massager;
• a rotating means includes at least one shaft with serial repetitive arrangement of rings and at least one angular groove slanted at one selected degree;
• at least one cam assembly with two corresponding half circular cam parts, the two corresponding half circular cam parts are joined at a joint and are established on a respective slanted angular groove of the at least one angular groove to complete the at least one cam assembly;
• at least one bearing is configured to accommodate the at least one shaft at a ring of the serial repetitive arrangement of rings;
• and at least one of a needle roller housing with a dedicated roller in a close proximity to a corresponding cam assembly at a position;
• a massaging means includes at least one set of knobs to provide percussive massage on a body of the user, at least one linear leaver is pivotal mounted, and the linear leaver interfaces with a dome bush;
• a supportive means includes a base strip to accommodate the bearing and the needle roller housing at intervals by way of a column;
• a board having a set of static knobs and/or a set of heating knobs are configured to contact the body of a user at one position,
• wherein the angular grooved shaft in a conjugation with the cam assembly and the needle roller housing provide conversion of axial rotational movement of the motor driven shaft to eccentric vertical movement in a form of synchronize percussive wave oscillation treatment through relatively different vertical position of the at least one set of knobs of the massaging means on an upper side of the board.
