Abstract

A vacuum breaker includes a safe valve body and an elastic gasket. The safe valve body has a receiving space which has a periphery provided with connecting holes. The elastic gasket has a size smaller than that of the receiving space, with clearances being defined between the elastic gasket and the receiving space. The elastic gasket has a center provided with a through hole and has an outer periphery provided with a sealing portion. Thus, the sealing portion contracts inward when water stops passing the safe valve body, so that ambient air flows into the receiving space to break a vacuum state in the safe valve body, such that a fluid contained in the safe valve body flows through the clearances between the elastic gasket and the safe valve body, and is drained outward from the connecting holes.
