Water purifier with function of reducing pure water TDS value

Abstract

The invention relates to the field of water purification, and discloses a water purifier with the function of reducing the TDS value of pure water, which comprises a raw water inlet pipe (1) and a reverse osmosis membrane filter element water inlet pipe (4) connected to the raw water inlet pipe (1) , the reverse osmosis membrane filter element water inlet pipe (4) is provided with a reverse osmosis membrane filter element (5), the pure water outlet of the reverse osmosis membrane filter element (5) is connected with a pure water outlet pipe (2), and the pure water outlet pipe (2) The first return pipe (7) connected with the reverse osmosis membrane filter element water inlet pipe (4) is connected on the top, and the first return flow solenoid valve (71) is provided on the first return flow pipe (7) and the flow direction is to flow into the reverse osmosis membrane filter element. The first one-way valve (72) of water pipe (4). In the present invention, by setting the first return pipe, the water before and after being treated by the reverse osmosis membrane filter element naturally convects, so that the TDS reaches a balance, and effectively reduces the TDS value on the pure water pipeline.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a water purifier with the function of reducing the TDS value of pure water. Background technique [0002] With the continuous improvement of people's quality of life, large-flux and fresh drinking water will soon become the mainstream of the water purification industry. Environmental safety and health issues have aroused great concern from the public. Due to the pollution of water sources and the flaws of the water supply system, there are impurities and solvents that are not beneficial to human health in people's domestic water, and the safety of drinking water has become one of the main issues that people generally pay attention to. The use of water purifiers provides people with a solution to the problem of drinking water safety. [0003] There are following problems in present water purifier: [0004] Waste water is relatively high, not water-saving. According to the perm...
