WATER-SAVING TYPE REVERSE OSMOSIS WATER PURIFYING MACHINE

摘要

A water-saving type reverse osmosis water purifying machine is provided. A prefiltration device (3,5,6), a preposition low-voltage switch (4), a water inlet solenoid valve (7), a reverse osmosis filter (9), a high-voltage switch (10), a pressure water storage barrel (11), a postposition activated carbon filter (12) and a water outlet tap (14) are installed in a pipeline of the water purifying machine. The preposition low-voltage switch (4), the water inlet solenoid valve (7) and the high-voltage switch (10) are electrically connected with a computer box (17). The water purifying machine also comprises a water outlet monitor (13,18,19) which is electrically connected with the computer box (17). The water outlet monitor (13,18,19) is used for monitoring the water outlet amount of the pressure water storage barrel (11) and enables the computer box (17) to start or stop the water purifying machine according to a monitoring result. The water purifying machine solves the problem of high discharge proportion of wastewater when needed water is little, and improves the water-saving effect.
