The purpose of this project is to improve the fan structure of the water vehicle oxygen supply machine.Mainly by means of one lift water turbine,A plurality of fan leaf modules and a plurality of combination parts are relatively formed；The left blade and the right blade provided by the plurality of fan die sets are brought up by the high-speed rotating impeller to make the two sides of the boundary area throw off water interactively.Make the raised water flowers cross and mix with each other to enlarge the area of water flowers.The lifting height and area of the water surface are increased.It can reduce the resistance of pumping water to reduce the resistance.Increase the contact time between water drops and space.Increase the dissolved oxygen and water flow area when pumping water.Also,In case of damage to a single blade die set,By slotting the elastic head end of the elastic-plastic joint, the elastic head end of the elastic-plastic joint can be movably compressed and inserted at the position relative to the hole group.To facilitate quick disassembly, replacement and assembly of parts and components.本創作係提供一種水車供氧機之扇葉結構改良，主要係藉由一揚水輪、複數扇葉模組及複數結合件所相對構成；藉此該複數扇葉模組所設置之左側葉片及右側葉片交互經由高轉速旋轉葉輪帶起而使分界區兩側交互甩水，使揚起的水花往彼此方向交叉混合帶入擴大水花面積，而使旋出水面之揚水高度及面積增加，可降低打水阻力以使阻力較小，增長水珠與空間接觸時間，提昇打水時之溶氧量及水流面積增加溶氧，再者，若單一扇葉模組發生損壞時，藉由該彈塑性結合件之彈性頭端之開槽可活動壓縮插拔於相對組孔位置，以便利於作快速拆卸更換零組件並組裝者。
