The invention provides an all-round head massage chair. The chair comprises a massage system, a massage helmet, four massage blades, twelve electromagnetic generators, sixteen connecting chain plates,twenty-four connecting pins, twelve massage cylinders and twelve electromagnetic induction moving steel balls and is characterized in that the four massage blades are symmetrically mounted on the circumference on the side of a connecting disc, and eight first hinge supporting plates are symmetrically mounted on the four massage blades respectively. The twenty-four connecting pins are respectivelyand fixedly mounted on two sides of the twelve electromagnetic generators. The massage chair adopts an electric cylinder, a motor and an electromagnetic field to change the linkage mode to achieve the massage action of a massage ball on the head in all directions. The magnetic field of the electromagnetic generators is changed, and the magnetic levitation principle is utilized to change the position of the electromagnetic induction steel balls at any frequency. By means of combined action of the electric cylinder and the motor behind the chair, a massager can be retracted into the chair backafter massage of the head to save space.
