Abstract: A toilet at least includes a container, a cover, and an inflator. The container includes a top opening and a bottom drain. The cover connects the container with a pivot for selectively shielding or exposing the top opening. When the cover shields the opening, the inflator supplies air into the container and makes the air pressure inside the container higher than the outside. And therefore, air flows and takes away wastes through the drain to the outside of the toilet due to the pressure differential.
