Disclosed is a mechanism for automatically changing closestool seat sanitary cover mainly includes a roll-up mechanism and a specially designed closestool seat. The roll-up mechanism includes a supply reel on which continuous sleeve-like sanitary cover is wound, an upper and a lower reels for pulling used sanitary cover away from the closestool seat, and a motor for rotating the upper and the lower reels in opposite directions. The closestool seat is substantially a C-shaped member having two end portions separately pointing to the supply reel and to the upper and the lower reels. A transverse beam laterally extends from near one end portion of the seat pointing to the upper and the lower reels and has short rods downward project from a bottom side thereof with springs put around them, such that the seat is normally slightly lifted away from the closestool by the springs, allowing the sleeve-like sanitary cover to be pulled from the supply reel to wrap around the end portion of the seat pointing to the supply reel. The sanitary cover can be then pulled along the seat toward the other end portion and be clamped between the upper and the lower reels. When the motor is started up, the upper and the lower reels are rotated in opposite directions to pull the used part of the sanitary cover to move backward so that new and clean sanitary cover can be pulled from the supply reel to wrap the seat for the next use. |
