Problems solved by technology

[0003] At present, reverse osmosis water purifiers are widely used to purify raw water, and remove bacteria, viruses and heavy metals in the water through reverse osmosis membranes. However, calcium and magnesium ion crystals gradually form on the surface of the membrane after long-term use, causing membrane blockage; especially Some water-saving reverse osmosis water purifiers, in order to increase the maximum water production rate, increase the waste water ratio, resulting in extremely high concentrations of calcium Ca and magnesium Mg ions at the raw water end of the reverse osmosis membrane, and it is easier to precipitate crystals, resulting in reverse osmosis membrane Blockage phenomenon

Abstract

The invention provides a flushing structure, a water purifier and a flushing method. The flushing structure comprises a high pressure pump, a reverse osmosis filter element, a first electromagnetic valve and a second electromagnetic valve; a concentrated water outlet of the reverse osmosis filter element is communicated with an inlet of the high pressure pump to form a loop; a Venturi pipe is arranged on a loop portion on which a concentrated water outlet of the reverse osmosis filter element is connected with a water inlet of the high pressure pump; the Venturi pipe comprises a water inlet and a water outlet, and a detergent inlet is arranged between the water inlet and the water outlet; and a detergent source is communicated with a detergent inlet of the venturi pipe by virtue of the second electromagnetic valve. The flushing structure of the invention can automatically circularly clean a reverse osmosis membrane, and can prolong the service life of the reverse osmosis filter element.
