    摘要： An aeration nozzle for spraying water infused with air into an above-ground water cavity defined by a wall, comprising a nozzle body having at least a first internal conical portion including an upstream end and a downstream end, the downstream end being smaller than the upstream end, a water way extending through the nozzle body and the first internal conical portion, an air way extending through the nozzle body, the air way intercepting the water way within the nozzle body downstream of the first internal conical portion, and a check valve disposed along the air way that permits air to be pulled through the air way and into the water way by way of a vacuum force caused by water flowing within the water way through the first internal conical portion and prevents water from entering the air way.

    摘要： The present disclosure provides a pool ladder with an active protection mechanism. The ladder provides a switch positioned at a significant height from the ground such that children cannot easily reach the switch. When actuated, the switch unlocks a protective door for the ladder and the ladder can be moved to access the steps. As such, the ladder can effectively prevent children from unlocking the protective door and accessing the pool.
