Because water is an essential substance for life and metabolism, an adult needs to drink 2000m 1-2500 ml of water every day under normal conditions. The quality of drinking water is directly related to the health degree of human body and the service life. According to the examination of world health organization, 80% of human diseases are related to water, and water quality is poor to cause various diseases. Tap water has long been considered safe and sanitary. However, tap water is often affected by water pollution, and the safety of tap water is questioned.
Along with the hidden trouble of water resource pollution, a batch of novel equipment, namely water purifiers aiming at purifying water quality are promoted and rapidly developed in a short time; the water purifier is an indispensable drinking water device for each family in the future for a longer time without any suspense. The water purifier can carry out deep filtration and purification treatment on water quality according to the use requirement of the water; for example: can effectively filter out rust, sand, colloid in water and adsorb chemical agents such as residual chlorine, odor, off-color, pesticide and the like in water. Can effectively remove bacteria, impurities, toxins, heavy metals and the like in water.
Although the development prospect of the water purifier is very bright and the market is huge, the water purifier has to be acknowledged to have a common disadvantage that waste water (namely concentrated water) is generated, which is a difficult problem in the water purification industry, so that the water purifier has a problem of waste water ratio when in use. The wastewater ratio refers to the ratio of pure water to wastewater (i.e., concentrate). In order to reduce the waste of water, the development of water purification equipment in future is a trend in the effort to improve the waste water ratio of the water purifier. However, because the water quality has regional differences, the TDS (Total dissolved solids) values of the water quality in different places are very different, and when the water purifiers are used in different regions, the same wastewater ratio is obviously not used, otherwise, serious water resource waste is caused. Therefore, the waste water ratio of the water purifier can be regulated according to the local water quality, and the waste of water resources is reduced.
In the prior art, the defects of water resource waste, small application range, poor user experience and the like exist.

For example: referring to the example shown in fig. 4, after the water inlet solenoid valve 1 is opened and raw water passes through the TDS detector 2, the TDS detector 2 feeds data back to the data collection module 41 of the TDS information processor, the data comparison module 42 compares the transmitted information with the original stored information, determines whether the current wastewater flow rate meets the current water quality, if not, feeds the current wastewater flow rate back to the action module, and the action module 43 sends an instruction to adjust the solenoid valves (e.g., the water inlet solenoid valve 1, the solenoid valves in the reflux unit 5, etc.) to act correspondingly.
For example: the TDS detector detects that the TDS value of raw water is low, and the TDS treater compares the TDS value that detects with the storage data of data comparison module in the treater, selects the optimal data, and this optimal data refers to the data that are closest with the detected value. The data module feeds back to the action module, and the action module sends out an instruction.
For example: if the water quality is poor, the processor can adjust the optimal data according to the closest TDS value and adjust the water purifier according to the optimal data, so that the hidden trouble of waste does not exist.

The data module feeds back to the action module, and the action module sends out an instruction.

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.
Therefore, the water purifier can conveniently and reliably control the water inflow in the water purifying process of the water purifier through the adaptation effect of data collection, data comparison and action sending, and is good in humanization.
