in an alternative example, adjusting the concentrate returning amount of the concentrate returning line and/or the concentrate discharging amount of the concentrate discharging line may further include: when the TDS value is higher than the set value, the concentrate reflux quantity of the concentrate reflux pipeline is reduced, and/or the concentrate discharge quantity of the concentrate discharge pipeline is increased.

For example: the instructions sent by the action module may further include: the electromagnetic valve in the reflux device 5 acts, and the water inlet and the water outlet of the electromagnetic valve are increased so as to increase the reflux speed of the waste water.

For example: the instructions sent by the action module may further include: the wastewater proportioner acts, the opening of the wastewater proportioner becomes small, and the discharge of concentrated water is reduced so as to compensate the water inlet flow in the filter element 3 of the water purifying device.

Since the processing and functions implemented by the control process of this embodiment substantially correspond to the embodiment, principle and example of the water purifier shown in fig. 4, the description of this embodiment is not given in detail, and reference may be made to the related description in the foregoing embodiment, which is not repeated herein.

Through a large number of tests, the technical scheme of the utility model is adopted, and a TDS detector is added behind the water inlet electromagnetic valve to detect the TDS value of the inlet water quality and feed back the value to the control circuit; the detection value difference obtained by the TDS value processor in the control circuit is used, and the water inlet quantity of the water inlet electromagnetic valve is adjusted according to the detection value difference, so that the water quantity under the current water quality is met, the waste of water is reduced, and the reliability is high.

In summary, it is readily understood by those skilled in the art that the advantageous modes described above can be freely combined and superimposed without conflict.

The above description is only an example of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
