一种智能马桶喷头性能系统的测试方法，具体为：
进行力学性能测试试验时，将力传感器8校零，设置信号分析装置13的参数，启动电子水泵2，喷头6喷射稳定后，力传感器8将采集到的信号传送至信号分析装置13，经过计算机14分析得到喷头6的水射流力学性能参数。如图9所示，利用拉伸力传感器可以得到击打力随时间关系，通过数值分析软件将测试数据进行小波变换和傅里叶变化可以得到喷头水射流击打力的上下幅值、脉冲频率及周期。
进行射流水力学性能测试试验时可同时进行射流水流速测试，将高速相机15调整好焦距，拍摄清洗水的运动形态，如图8所示，可以看出射流的形态，由于气泡的作用，连续射流变为水滴形态流动，并在一定的周期内形成大水滴，将高速相机15拍摄的图片传递至计算机14，根据相邻图片的时间差，运用图片分析软件得到相邻图片中水滴位移量，从而得到水射流流速。
进行清洗性能测试试验时，将果酱涂满栅格10并正对喷头6，喷头6运行30s后关 闭电子水泵2，利用照相机拍摄栅格10，将照片传递给计算机14中的图像分析软件得到喷头6的面积清洗率以及体积清洗率，从而比较不同喷头6的冲洗效果。
所述实施例为本发明的优选的实施方式，但本发明并不限于上述实施方式，在不背离本发明的实质内容的情况下，本领域技术人员能够做出的任何显而易见的改进、替换或变型均属于本发明的保护范围。
