Abstract: In public restrooms, many people do not lift a toilet seat after use; the following man may just urinate without lifting the seat too. So the toilet seat is polluted. There are many devices try to automatically keep toilet seat upright, but they are too complicated or too expensive, so those devices are not easy to implement. We seldom see auto-lifting toilet seat in public restrooms. This device is very simple, but it is easy to implement and really solve the problem. It can keep the toilet seat clean. The device uses one or two torsion springs in a regular toilet to keep the toilet seat and toilet cover upright.
