Partial impurity filtering, after filtering more impurities, the pressure difference on both sides of the filter 12 increases, which is convenient for detecting the pressure difference on both ends of the filter 12. When there are too many impurities or a fault occurs, the electric valve three 9 is opened and the electric valve two 8 is closed, so that the transmitted water flows back to the energy equipment 5 at the return pipe 10, and the water is no longer sent to the user end, thereby reducing the situation of transmitting more debris to the user end, which is conducive to automatic monitoring and control of the transmitted water, and is convenient for automatic processing of blockage faults. Through the use of different energy sources and a structure that is easy to maintain, it is beneficial to save part of the energy and improve the utilization rate.

[0022] The energy-saving control device also includes a main control component, which includes a pressure gauge 2 15, a water pump 16 and a pressure gauge 3 17.
