The invention discloses a spray pump structure for a surfboard, and relates to the technical field of surfboards. The spray pump structure comprises a fixed cover, a propeller assembly and a power source, wherein the fixed cover is fixedly assembled with the surfboard, and a water inlet is formed in the fixed cover; the propeller assembly is arranged on one side, which is close to the tail of thesurfboard, in the fixed cover and is used for discharging water from the water inlet out of the fixed cover through the rotation of the propeller assembly so as to form reverse thrust on the surfboard; and the power source is arranged in the fixed cover and is located on the side, which is away from the tail of the surfboard, in the fixed cover, the power source comprises a stator which is fixedlyassembled in the fixed cover, an outer rotor which is arranged in the fixed cover and a bearing which is arranged between the outer rotor and the stator, one end, which is close to the stator, of theouter rotor is rotatably assembled with the stator in a sealed mode, the other end of the outer rotor is fixedly assembled with the propeller assembly, and after the power source is energized, the outer rotor rotates relative to the stator so as to drive the propeller assembly to rotate. The spray pump structure adopting the technical scheme has the advantages of small installation space, long service life and good waterproof effect of a motor.
一种用于冲浪板的喷泵结构,它涉及冲浪板技术领域。它包括:与冲浪板固定装配的固定罩,固定罩上设置有入水口;设置于固定罩内靠近冲浪板尾部一侧的、用于通过自身转动将入水口进入的水排出固定罩内以对冲浪板形成反向推力的螺旋桨组件;以及,设置于固定罩内并位于固定罩内远离冲浪板尾部一侧的动力源;动力源包括:固定装配于固定罩内的定子;设置于固定罩内的外转子,外转子上靠近定子一端与定子转动密封装配,外转子另一端与螺旋桨组件固定装配,在动力源通电后,外转子相对于定子转动以驱动螺旋桨组件转动;以及,设置于外转子与定子之间的轴承。采用上述技术方案的喷泵结构,具有安装空间小,使用寿命长,电机防水效果好的优势。
