In addition, a hole is opened at the lower end of the distribution box 2 to allow the external power line to provide power to the power supply cable inside the distribution box 2. The impeller housing 3 can provide a position for the installation of the anti-idling component. A combination of a rotating shaft 4, an impeller 5 and a generator 6 is adopted. When water flows through the inside of the impeller housing 3, the impeller 5 on the lower surface of the rotating shaft 4 is driven to rotate by the water flow inside the impeller housing 3, thereby generating electricity through the generator 6 on the upper surface of the impeller 5, and utilizing The power generation of the generator 6 indicates that there is water flowing inside the pressure tank and the device will not idle. The thermal relay 7 connects the generator 6 with the electronic controller of the water pump inside the distribution box 2. When the current generated by the generator 6 through power generation is too low, the thermal relay 7 will automatically cut off the circuit. When the electronic controller inside the distribution box 2 does not receive the current generated by the thermal relay 7, it will automatically cut off the circuit of the power supply cable of the water pump assembly, thereby preventing the device from idling.
