The working phase and principle are as follows:

soft water: raw water enters a cold and hot resin tank of a water softener through cold and hot angle valves respectively, the raw water is changed into ' softened water ' after being replaced by ion exchange resin in the resin tank, redundant ' residual chlorine ' and relevant ' impurities are filtered out through a KDF filter element tank and then enter cold and hot water pipes of a faucet respectively, the process needs to detect the flow, a flow sensor is placed in each cold and hot water path of the water softener, when water flows through the flow sensor, the flow sensor transmits the flow information to a microcontroller (Micro Control Unit, MCU) serving as acontroller 1 and stores the flow information, the MCU can also feed the information back to a display screen at any time and transmit the information to an APP interface of a user mobile phone through an IOT (input/output) of awireless communicator 4.

Regeneration: after the water softener works for a period of time, the ion exchange resin is fully adsorbed with calcium and magnesium ions, the water softener resin is cleaned by soft water salt (ion exchange resin regenerant) at the moment, the replacement capacity of the water softener is recovered, the process mainly depends on the memory function of the MCU, when the recorded standard flow is the same as the actual use flow, the MCU actively sends an instruction to four stepping motors serving as thevalve core motors 2, the four stepping motors respectively drive the valve cores to rotate, the water path switching components are formed, brine stored in the salt box respectively flows through the cold and hot resin tanks, and then is discharged through the waste water pipe.

And after the salt tankliquid level sensor 8 in the salt tank detects that the water level meets the requirement, sending a signal to the MCU, and sending the signal to the stepping motor by the MCU to adjust the position of the valve core and stop injecting water.

Backwashing the cold and hot resin tank: when MCU memory procedure thinks that the water softener needs "regeneration", can carry out the back flush to cold and hot resin jar at first, reach and get rid of iron fillings, purpose such as silt, the process is: MCU informs motor turned angle, forms the backwash water route through the case, and rivers are reverse to be passed through the resin tank fast, get rid of from the drain, and after passing through certain water yield, adjust the water route once more, stop the backwash.

Positive flushing of cold and hot resin tanks: after the action of "regeneration" is ended, MCU passes through step motor control case, forms and just washes the water route, and remaining unnecessary salt solution in the resin tank takes away through the blow off pipe when will "regeneration", prevents to cause not good experience for the customer. By flow monitoring, the positive flush action is stopped.
