Abstract
A pool apparatus includes a pool body, a water inlet, a water outlet, and an outlet valve. The water inlet is used for carrying water into the pool body. The water outlet is used for draining water out of the pool body. The outlet valve covers the water outlet. The outlet valve has a drainage surface for draining water out of the pool body from the drainage surface with a drainage direction. The outlet valve has a protrusion block protruding with a distance opposite to the drainage direction from the drainage surface to decrease the risk that the user may be sucked on the outlet valve.
