A reverse osmosis water purification device

Abstract

The invention discloses a reverse osmosis water purifying device, belongs to the field of water purifying devices and aims at solving the problem of a relatively large service life difference of a reverse osmosis filter element caused by a fixed pure water production rate. The reverse osmosis water purifying device mainly comprises a control chip, a booster pump, and a reverse osmosis filter element, wherein the booster pump is arranged at the upstream of the reverse osmosis filter element. The reverse osmosis water purifying device is characterized in that a wastewater outlet of the reverse osmosis filter element is connected with a wastewater path with multiple gears of wastewater ratios; a water quality probe for detecting TDS of inlet water and a temperature probe for detecting a temperature of the inlet water are arranged at the upstream side of a water inlet of the reverse osmosis filter element; the water quality probe, the temperature probe and the control chip are electrically connected; and the control chip adjusts the wastewater path according to the TDS and the temperature of the inlet water and different gears of wastewater ratios are adopted. The reverse osmosis water purifying device is mainly used for purifying water.

Description

technical field [0001] The invention relates to a water purification device, in particular to a reverse osmosis water purification device. Background technique [0002] In recent years, water purification products have attracted more and more attention from consumers as health products, and the water purification industry has also developed rapidly. The reverse osmosis water purification device is the mainstream type of domestic household water purification products. In order to ensure the service life of the reverse osmosis filter element, the surface of the reverse osmosis membrane must be continuously flushed during use to reduce the salt concentration on the surface of the reverse osmosis membrane. Slow down the clogging caused by fouling on the surface of the membrane and reduce the discharge of concentrated water. Under the premise of ensuring the service life of the reverse osmosis membrane, it is the common goal of the industry to increase the water production rate ...

AI Technical Summary

Problems solved by technology

However, most of the reverse osmosis water purifiers currently on the market have a fixed pure water production rate, which cannot meet the water quality conditions in different regions, and the service life of the reverse osmosis filter element also varies greatly.

[0003] Since the pure water production rate of the reverse osmosis membrane is greatly affected by the feed water temperature, when the feed water temperature is lower than a certain temperature, the pure water production rate of the reverse osmosis water purification device will seriously drop

In addition, in different places, the day and night temperature varies greatly throughout the year. Many reverse osmosis water purification devices may work in a low temperature environment below 0 degrees, and the inlet water temperature is lower than -5 degrees. If the reverse osmosis water purification device does not work If the time exceeds 3 hours, the water stored in the reverse osmosis membrane is likely to freeze, which will cause the reverse osmosis membrane to freeze and crack
