In addition, the controller 4 may employ different control elements and control logic according to additional functions. For example: if only automatic flushing is performed, a microcomputer time control switch can be used; if other function displays (such as water making state, filter element service life, real-time flow and other information) are added, the integrated chip is adopted for logic control.

The primary filter 6 is connected with the raw water pipe a in series, and is used for primarily filtering the tap water, removing large-particle colloid impurities and protecting a subsequent device.

The washing mode of the membrane wires in the pipeline machine main body 1 is similar to that of the pre-filter 6, and the control of the washing is realized by opening and closing the electromagnetic valve 5.

The signal of flushing is given by a preset threshold value, the threshold value can be the flow of the purified water or the water passing time of the whole machine, and the threshold value can be adjusted and set according to the local water quality and the use frequency.

Further, the control part (for example, the controller 4) is provided with a display screen which can display a standby state, a water production state, a flushing state, a setting state, prompt information (service life, water leakage, real-time flow and the like) and the like.

Further, the power demand of the control part (for example, the controller 4) is derived from the power supply and storage device 3, and energy is saved.

In one example, when the water purifier comprises the pre-filter 6 and the bypass switch, the flushing of the filter screen in the pre-filter 6 and the discharge of sewage generated by the flushing of the filter screen are controlled by the bypass switch. Through the control that the filter screen to leading filter washes and the filter screen washes production sewage discharge, can reduce the dirty stifled of filter screen, increase the life of filter screen, be favorable to further promoting the security and the reliability of the whole water purification operation of purifier.
