This creation is that a kind of atomizer at related aerator Submersible Pump Pu is improved, refering in particular to one kind includes that a Submersible Pump Pu, a pipeline section and a nut cap group are set, the Submersible Pump Pu is equipped with pipeline section, and the pipeline section group is equipped with nut cap, its characteristic is in what: the nut cap top surface is equipped with plural nozzle head, and the nozzle head is equipped with an atomizer, the another nozzle head system is arranged in a ring, and it tilts at an angle, thereby, the water that Submersible Pump Pu is pumped can generate atomizating phenomenon from atomizer, to reach the effect for increasing water oxygen.本創作係有關一種增氧機沈水泵浦之霧化噴頭改良，特指一種包含有一沈水泵浦、一管段及一蓋帽組設而成，該沈水泵浦接設有管段，而該管段組設有蓋帽，其特徵在於：該蓋帽頂面設有複數噴嘴頭，而該噴嘴頭接設有一霧化噴頭，另該噴嘴頭係呈環形排列，且呈一定角度傾斜，藉此，沈水泵浦所抽送之水可從霧化噴頭產生霧化現象，以達到增加水中氧氣之效果。
