Reverse osmosis water purifier

Abstract

The invention relates to a reverse osmosis water purifier. The reverse osmosis water purifier comprises pre-treatment filter elements, a booster pump, and reverse osmosis filter elements. A tap water inlet is connected with the first pre-treatment filter element, the booster pump, the second pre-treatment filter element and the reverse osmosis filter elements sequentially; the condense water branch and the filter water branch of the reverse osmosis filter elements are connected with a condense water outlet and a purified water outlet respectively; two reverse osmosis filter elements are connected in parallel, the condense water branches of the two reverse osmosis filter elements are connected in parallel and then connected to a condense water outlet, and the filter water branches of the two reverse osmosis filter elements are connected in parallel and then connected to a purified water outlet; and a liquid flow meter is arranged between the booster pump and the pre-treatment filter elements and the booster pump starts or stop working based on the flow rate signal detected by the liquid flow meter. The water purifier adopts the parallel connection way of the reverse osmosis membrane filter elements, and uses the liquid flow meter to control the booster pump to realize water pressure boosting, and guarantee water outflow. The water purifier has safe water outflow, is simple and convenient to operate, and has no water storage tank.

Description

Technical field [0001] The invention involves a reverse osmosis water purifier used in households or public places, which belongs to the improvement of water treatment technology, especially the improvement technology of reverse osmosis and water treatment system. Background technique [0002] In the environment of the water purifier, affected by the structural characteristics of the reverse osmosis membrane element itself, the water production of ordinary reverse osmosis water purifiers can only reach 100 to 500ml / min.During the process, the pure water produced by the water storage tank is needed to use it for later use. Because it is impossible to filter and drink, the pure water in the water storage tank is also risk for bacterial pollution; in addition, the water storage tank is due to its own itself.The structural characteristics will increase the proportion of concentrated water, which will cause waste of water resources to a certain extent.Although some designs can save w...

AI Technical Summary

Problems solved by technology

[0002] In the environment where the water purifier is used, affected by the structural characteristics of the reverse osmosis membrane element itself, the water production of the ordinary reverse osmosis water purifier can only reach 100 ~500ml / min, due to its small water production, during use, it is necessary to collect the produced pure water with the help of a water storage tank for later use. There is also the risk of being contaminated by bacteria; in addition, due to its own structural characteristics, the water storage tank will increase the proportion of concentrated water relatively, resulting in a waste of water resources to a certain extent

Although some designs can save water to a certain extent (such as 200610147719.3), if the water storage tank exists, the loss of water resources is inevitable
