The reverse osmosis membrane is a semipermeable membrane suitable for water solution, only water molecules can pass through the reverse osmosis membrane, but other solutes cannot pass through the reverse osmosis membrane, so that the purpose of preparing pure water is achieved. The reverse osmosis membrane water yield is directly related to the effective area of the membrane and the pressure in front of the membrane, and the reverse osmosis water purifier without the water storage barrel generally adopts a large-flux reverse osmosis membrane or an ultra-low-pressure large-flux reverse osmosis membrane with the enlarged effective area and is realized by controlling the pressure in front of the reverse osmosis membrane.
When the reverse osmosis water purifier without the water storage barrel produces pure water, the pressure in front of the reverse osmosis membrane reaches the set pressure value of the reverse osmosis membrane; the household water supply pressure system of a common user is unstable, the water pressure is suddenly high and suddenly low, and a pressure reducing valve and a booster pump system are additionally arranged in the water purifier system in order to ensure the safety of the reverse osmosis water purifier under pressure impact and the normal water production pressure; the cost of the reverse osmosis membrane is high, and in order to reduce the use cost of a user, a rough filtration system is added at the front end of the reverse osmosis membrane, so that the filtration burden of the reverse osmosis membrane is reduced, and the service life of the reverse osmosis membrane is prolonged; the water filtered by the reverse osmosis membrane is divided into two paths, one path is pure water which can be directly drunk, the reverse osmosis water purifier stops working and is in a standby state under the control of a high-voltage switch, and the other path is concentrated water which is directly drained through a concentrated water ratio combination valve or used for washing dishes, watering flowers, mopping floors and the like.
The condition that the water pressure is too low or water shortage can occur in the tap water supply systems of various regions, the reverse osmosis water purifier is always in an idle working state at the moment, internal parts of the reverse osmosis water purifier are abraded, the service life is shortened, particularly a booster pump system idles for a long time, the system is in a heating state for a long time, the internal parts of the booster pump are deformed and are easy to leak water, and unnecessary electric energy loss is brought to users; in order to solve the problem, the conventional reverse osmosis water purifier is additionally provided with a low-pressure switch at the front end for controlling, and the water purifier directly stops running when the water pressure is too low or water is short, so that internal parts are protected from being damaged, and the service lives of the parts are prolonged. But the water purifier without the water storage barrel can automatically stop under the condition that the water pressure is insufficient or the water is short of the water under the control of the low-pressure switch is avoided, and the limitation on the high-pressure switch is avoided.
In addition, the existing water purifier mostly adopts the front filter element and the rear filter element to carry out front and rear filtration, differs according to the water quality standard, a certain amount of water can reach the drinking standard through the front filter element filtration, but does not have a TDS detector in the existing water purifier for the most part, so the water purifier basically filters through the rear filter element, the waste of the filter element is caused, the service life of the filter element is shortened, and meanwhile, the energy conservation and the environmental protection of the water purifier are not facilitated.
