The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention and should not be construed as limiting the present invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Because the existing reverse osmosis membrane adopts a tap water washing membrane, tap water TDS values in all places are different, so that the flushing is not clean, the TDS value of a waste water end is high, the membrane is easy to crystallize and block on the surface of the membrane, and a high TDS machine can generate forward osmosis when the machine stops working, so that the TDS of a pure water end is also increased, and a first cup of water of the pure water end is polluted, therefore, in the prior art, a set of backflow prevention device is specially added for cleaning the reverse osmosis membrane aiming at tap water washing membrane equipment, so that the device structure is complex, and the embodiment of the invention discloses an air bag pure water washing membrane system, and referring to the attached drawings 1-3, a composite filter element filter 1, a booster pump 2, a reverse osmosis membrane filter element filter 3 and a rear active carbon filter element filter 4 are sequentially connected between a water inlet pipeline and a water outlet pipeline; the interior of the rear activated carbon filter element filter 4 is divided into an upper chamber and a lower chamber which are separated from each other, an air bag 41 is arranged in the bottom chamber, the top of the air bag 41 is connected with a central tube 42, the central tube 42 penetrates through the upper filter element chamber and extends outwards, and a water inlet electromagnetic valve II 7 is connected between the extending pipeline and the water removal direction pipeline of the booster pump 2; a water inlet electromagnetic valve I5 and a TDS probe I6 are arranged between the composite filter element filter 1 and a water inlet direction pipeline of the booster pump 2; a check valve 8 is connected between a pipeline from the reverse osmosis membrane filter element filter 3 to the rear active carbon filter element filter 4 in the water removal direction and an extension pipeline of the central tube 42; the reverse osmosis membrane filter element filter 3 is connected with a wastewater electromagnetic valve 9; and a high-voltage switch 10 for switch equipment is installed on the water outlet pipeline.
According to the invention, the air bag is arranged in the filtering pipeline and is positioned in the bottom cavity of the rear active carbon filter element filter, so that the structure is simplified, and meanwhile, the first cup of water which does not work for a long time can be guaranteed to be fresh and drinkable.
The system is electrified and started, the water inlet electromagnetic valve is opened, tap water enters the composite filter element, pressure is provided for the RO membrane by the additional pump, and at the moment, pure water of the RO membrane enters the rear active carbon filter element and then flows into the water outlet pipeline from the rear active carbon filter element. At this time, if the water inlet pipeline is in an open state, pure water can flow out of the water outlet pipeline all the time.
If the water inlet pipeline is closed and the pressure is greater than 0.05MPa, the check valve 8 is opened, pure water is introduced into the air bag through the central pipe, air in the air bag can be compressed by the water pressure until the water pressure is greater than a set value of a high-pressure switch (generally, the pressure of the high-pressure switch is 0.2-0.25 MPa), and the machine is stopped.
At the moment, the waste water electromagnetic valve is opened for 3 seconds to discharge redundant waste water discharged by the pressure in the RO membrane cavity and then closed, after the waste water is discharged, the water inlet electromagnetic valve II is opened, the waste water electromagnetic valve simultaneously opens pure water in the discharging air bag to wash the surface of the RO membrane, and the TDS value of the waste water end of the RO membrane is rapidly reduced.
Therefore, the TDS value of the reverse osmosis membrane wastewater end can be reduced, the RO membrane blockage caused by reverse osmosis membrane wastewater end crystallization is reduced, and the service life of the filter element is prolonged.
Because the TDS value of reverse osmosis waste water end is very close with pure water end TDS value, the system is producing positive permeation at the inoperative, the one end that TDS value concentration is high permeates to the one end that the concentration is low, because system pure water end and waste water end TDS value all are very low so even take place the TDS of positive osmosis pure water end and also can reach the desalination standard of reverse osmosis, reach the first cup of water that the system was out of operation for a long time from this and also be fresh drinkable.
Wherein, forward osmosis refers to the phenomenon of water molecules diffusing through a semipermeable membrane. It penetrates from the high water molecular region (i.e., low concentration solution) into the low water molecular region (i.e., high concentration solution) until the water molecules reach a dynamic equilibrium across the semi-permeable membrane.
The reverse osmosis method is a membrane separation operation method for separating a solvent from a solution by using a pressure difference as a driving force. It applies pressure to the feed liquid on one side of the membrane, and when the pressure exceeds its osmotic pressure, the solvent will reverse osmosis against the direction of natural osmosis, thus obtaining a permeated solvent, i.e. permeate, on the low pressure side of the membrane; the high pressure side yields a concentrated solution, i.e., a concentrate.
In the above embodiment, the composite filter element 1 includes a PP cotton filter element and an activated carbon filter element.
Advantageously, the location where the center tube 42 exits the upper cartridge chamber is sealed by a gasket 43, preventing water from escaping from the upper and lower cartridge chambers.

In another specific embodiment of the present invention, the bottom chamber and the upper cartridge chamber are removably connected. A threaded connection may be used and a seal added at the threaded connection.
In the above embodiment, the opening pressure of the check valve 8 may be 0.05MPa.
The present invention includes the following modes:
in the first mode, inlet water is filtered by a composite filter element filter, pressurized by a booster pump, a reverse osmosis membrane filter element filter and a rear active carbon filter element filter in sequence, and then is discharged through a water outlet pipeline;
in the second mode, water inlet is closed, when the pressure in the system exceeds the opening pressure of the check valve, the check valve is opened, pure water filtered in the reverse osmosis membrane filter element filter enters the air bag through the check valve and the central pipe, the air pressure in the air bag is compressed, and the equipment is closed when the pressure is higher than the opening value of the high-pressure switch;
after mode three, equipment are closed, the waste water solenoid valve is opened and is predetermine the time, and partial waste water is drained to the pressure in the reverse osmosis membrane cavity, and the waste water solenoid valve is closed, and waste water discharge back, solenoid valve two are opened, and the waste water solenoid valve is opened simultaneously this moment, and pure water in the gasbag washes the TDS value that reverse osmosis membrane surface reduces the reverse osmosis membrane waste water end through the center tube, keeps the TDS value of reverse osmosis membrane waste water end to be close the TDS value of pure water end.
The invention reduces the TDS value of the reverse osmosis membrane waste water end, prevents the RO membrane from being blocked by TDS high crystallization and prolongs the service life of the filter element. Because the TDS value of reverse osmosis waste water end is very close with pure water end TDS value, equipment produces the positive osmosis when out of work, and the one end that the TDS value concentration is high permeates to the one end that the concentration is low, reaches that the device is out of work for a long time first cup of water also is fresh drinkable.
