Beschreibung
Zusammenfassung:	A water circulation system for a pool comprises a water outlet assembly mounted to an inner wall of a pool, and in fluid communication with an external pump through a water outlet pipe. The water circulation system also includes an air inlet assembly mounted to the pool a preset distance from the water outlet assembly, and an air outlet assembly attached to the water outlet assembly and in fluid communication with the water outlet assembly. An air inlet passage connects the air inlet assembly to the air outlet assembly, so external air can enter the air inlet assembly and be introduced to the water outlet assembly through the air outlet assembly. Air is introduced to the water outlet by the air outlet when the water outlet assembly is blocked, reducing negative pressure at the water outlet and reducing risk that a portion of a user's body is drawn against or into the water outlet.
