Whole-house hierarchical water purification system

Abstract

The invention discloses a whole-house hierarchical water purification system, comprising a front water purifying device, an inflow water detection device, a hierarchical filtering device, an outflow water detection device, a direct drinking water device and a micro-computer controller, wherein the front water purifying device physically filters tap water; the inflow water detection device and the outflow water detection device respectively detect the indexes of water before and after filtering and transmit detection results to the micro-computer controller in real time; the micro-computer controller determines different filtering grades according to the grades of water quality; and differences of index data detected by the inflow water detection device and the outflow water detection device are used for statistics of the service life of a filter core. The whole-house hierarchical water purification system can carry out hierarchical purification after detection of water quality, improves the usage efficiency and life of the filter core, and guarantees the quality of purified water; the micro-computer controller has adjustable parameters, is sensitive in reaction and can be communicated with other equipment to facilitate operation; and a filter core assembly can be separately replaced, and safety and environmental protection are realized.

Description

technical field [0001] The invention relates to a whole-house graded water purification system, which belongs to the field of domestic water treatment. Background technique [0002] With the intensification of global water pollution, the location of tap water intakes is constantly moving, but the deterioration of water quality cannot be avoided. Although the factory water of the water company can meet the drinking standard, due to the gradual aging of the urban water pipe network system and the hygiene problems of the secondary water supply in various residential areas, the quality of the tap water is still very unstable. 70% of the human body is composed of water, and the safety of water quality directly affects the quality of life, so the purification of household tap water is particularly important. [0003] As a hot-selling product in recent years, household water purifiers have various brands and models of water purification products on the market, and the principles a...

Problems solved by technology

But the problem is: the flow rate is small, which cannot fully meet the domestic water demand; the function is single, and often can only meet one aspect of water use. For example, the flow rate of a household RO (reverse osmosis membrane) machine is generally only 6-8L / H, which is very satisfying for drinking. Nervous; the service life of the filter element is short, frequent replacement, high cost and inconvenient

[0014] The filter elements currently used in the market are all integrated filter elements. If replacement is required, only the filter element as a whole can be replaced. It is impossible to determine whether all the filter layers are fully loaded.

However, due to the great difference in water quality in different regions, the water treatment for different regions should also be different; the water quality in the same region also has certain fluctuations in different stages, and the requirements for filtration are also different under different water quality, so the use of exactly the same It is very unenvironmentally friendly to purify the filter element
