This invention relates to a water circuit switching structure and a toilet, characterized by comprising a water tank, a float, and a limiting block. The water tank has an inlet, a first outlet, and a second outlet. The float is movably positioned between the inlet, the first outlet, and the second outlet. The limiting block is located inside the water tank. When water enters through the inlet, the limiting block restricts the float to a first position, connecting the inlet to the first outlet. When water stops flowing through the inlet, the limiting block releases the float, and the float moves to a second position under buoyancy, resuming water supply to the inlet and maintaining the float in the second position, connecting the inlet to the second outlet. This invention has the following advantages: 1. It reduces reliance on a motor, reducing the occurrence of malfunctions. 2. The switching structure is simple, stable, and reliable, offering significant cost advantages. 3. It has a wide range of applications.

The invention relates to the technical field of medical auxiliary instruments, and discloses orthopedic knee joint rehabilitation auxiliary equipment which comprises rehabilitation chair supporting legs, a chair frame is mounted at the tops of the rehabilitation chair supporting legs, a sponge cushion is mounted at the top of the chair frame, a transverse rod is mounted at the bottom of the chair frame, and a rehabilitation training mechanism is mounted on the outer edge of the transverse rod. Through the arrangement of the passive telescopic cylinder and the active telescopic cylinder, the telescopic lead screw can drive the passive telescopic cylinder to stretch out and draw back in the active telescopic cylinder, so that the crus placing frame connected to the passive telescopic cylinder can be passively moved, and the patient lifts the crus to drive the crus placing frame and the active telescopic cylinder to move; the active telescopic cylinder moves to drive the first one-way valve and the second one-way valve to move, so that the patient can do active movement, and the problems that knee joint rehabilitation equipment is single in function, only a passive movement mode can be adopted from the initial stage to the final stage of rehabilitation of the patient, and an active training mode cannot be switched according to the rehabilitation stage of the patient are solved.

The application belongs to the technical field of robots, and discloses an amphibious robot propulsion device and method based on a wheel-propeller composite structure. The device is integrated with a reduction motor driving system of a wheel mechanism and a composite propeller system of a propeller mechanism, and outputs propulsion power in the same coaxial direction. The reduction motor driving system takes a waterproof reduction motor as a driver to provide power for the amphibious robot when walking on the ground. The composite propeller system takes a propeller as a driving component to provide power for the amphibious robot when floating in water. The application can interact with other structures to form vector propulsion, increase controllability and stability of the robot, and quickly switch between water and land modes. The switching structure is simple. Most amphibious robot water-land switching structures are too complex, which causes great pressure on the body space and reduces the practicability of the product.
