Abstract: A leg massage using air is provided. The leg massager includes a U-shaped massaging portion, a supporting frame, an air tank, an air supply controller, a rotating plate, an optical sensor, an air pump, and a control unit. The control unit determines a rotation angle of the rotating plate through the optical sensor, to control the operation of the air pump and the supply of compressed air to the air pads.

Abstract: A thermoceramic lifter of a thermotherapy apparatus that applies pressure to acupressure points of a user and smoothly and silently raises and lowers itself as needed, applies pressure comfortably to local areas as specified by the user, and has a simple lifting structure, is provided. The lifter (200) of a thermoceramic unit (100) lifts and lowers the thermoceramic unit (100) at a predetermined location along a lengthwise movement of the thermoceramic unit (100). The lengthwise movement is enabled by a conveyor in the thermotherapy apparatus. The lifter (200) includes a box-shaped guiding block (220), a geared motor (210) installed opposite to the open side of the guiding block (220), a sliding block (230) raised and lowered within the guiding block (220) linear movement, and a cover plate (240) to cover the open side of the guiding block (220).
