Automatic raising and controlled lowering of a toilet seat

A device comprising:

• a fluid-based movement source that generates a force upon actuation, the fluid-based movement source including a fluid inlet fluidly connected to a water supply and a fluid outlet located downstream of the fluid inlet and fluidly connected to a flush valve of the toilet, the fluid inlet being coupled to the fluid outlet, the fluid-based movement source being actuatable by a fluid flow regulated by the flush valve of the toilet during a single flush cycle to generate the force based on a pressure difference between the fluid inlet and the fluid outlet that causes the fluid flow to flow in the fluid inlet and out of the fluid outlet towards the flush valve during the single flush cycle when actuated by the flush valve of the toilet, the fluid-based movement source being fixable to a toilet having a toilet seat and a toilet bowl;
• and
• a movement transmission mechanism configured to transfer the force to the toilet seat to raise the toilet seat from a lowered position to a raised position, the movement transmission mechanism being connected to the fluid-based movement source to receive the force and being coupleable to the toilet seat.
