    • A portable pump assembly having a hollow housing with enlarged top and bottom is provided for holding a motor, switch, and battery pack. A pump chamber is formed on the underside of the housing and houses a pump impeller mounted on the end of the motor shaft. A flexible discharge tube extends from the pump and passes through an opening in the enlarged bottom such that the tube may be conveniently wrapped around the housing for storage or extended for use. A removable cover provides an easy access for replacing batteries. Further, the batteries are carried in a battery pack which plugs into a receptacle in the housing, thus simplifying and speeding battery replacement.
    • 提供具有放大的顶部和底部的中空壳体的便携式泵组件,用于保持马达,开关和电池组。 泵壳体形成在壳体的下侧,并容纳安装在电动机轴端部上的泵叶轮。 柔性排放管从泵延伸并且通过扩大底部中的开口,使得管可以方便地缠绕在壳体周围用于存储或延伸使用。 可拆卸盖可以方便地更换电池。 此外,电池被携带在插入壳体中的插座的电池组中,从而简化和加速电池更换。
