The invention provides an intelligent bath nursing robot. A movable seat structure is adopted, a manual button is arranged on an auxiliary arm support device and used for monitoring operation and service conditions of the robot and monitoring vital signs of a bather. The intelligent bath nursing robot is capable of providing standing assisting, leg bathing, hip bathing, back bathing and head bathing functions for the bather, and a mechanical structure capable of automatically adapting to a human body curve is adopted for every bathing mechanism. The head of the bather can be positioned accurately to realize automatic hair positioning and washing, a plurality of claw-shaped hair bathing units are arranged on a hat shell and can almost cover the entire head, and through reciprocation of guide rods, spring boards deform and stretch continuously to simulate hair grabbing and washing actions and head massaging actions of human hands. A water pressure sensor and a hydraulic valve are arranged on a water inlet tube to adjust water pressure and water inflow of the water inlet tube, so that stability of water pressure during bathing is guaranteed, the bather can feel comfortable with appropriate water flow and water pressure. Leakage holes are formed in a water outlet tube, so that automatic water feeding and water draining can be realized, and indoor water accumulation can be avoided.
