Fig. 1 is a schematic structural diagram of an embodiment of the present invention, referring to fig. 1, an embodiment of the present invention provides a structure capable of reducing a salt rejection rate of effluent, including a filter flask 100 and a filter material 200 in the filter flask 100, and a filter element end cap 300 is disposed on the filter flask 100. The filter element end cap 300 is connected to the water pipe as the water passage side of the filter element structure, the filter element end cap 300 is provided with a filter element end cap water passage opening, and the water pipe is connected to the filter element end cap water passage opening to enter the filter bottle 100 and is filtered through the filter material 200.

The filter element end cover 300 is provided with an outermost source water inlet annular cavity 310, an outermost waste water outlet annular cavity 320 and an innermost pure water outlet cavity 330 in sequence. The source water inlet annular cavity 310, the waste water outlet annular cavity 320 and the pure water outlet cavity 330 are respectively communicated with the corresponding water through pipe ports of the filter element cover and are respectively connected with a source water pipe, a waste water pipe and a pure water pipe.

The filter medium 200 has a cylindrical structure, a space between the inside of the filter flask 100 and the filter medium 200 is a source water space 110, and the filter medium 200 includes an RO membrane and a filter screen. The filter material 200 may be specifically formed by laminating and winding an RO membrane and a filter mesh sheet, or by laminating and hot-pressing an RO membrane and a filter mesh sheet, or by other existing processes, and is not limited herein.

The hollow part of the filter material 200 is provided with a conduit 400, the conduit 400 is provided with a water through hole, and the filtered pure water can enter the conduit 400 through the water through hole of the conduit 400. Since the filter 200 is attached to the duct 400, the inner diameter of the filter 200 is close to the outer diameter of the duct 400. The upper end of the conduit 400 is communicated with the pure water outlet cavity 330, and the ratio of the outer diameter of the filter material 200 to the inner diameter of the conduit 400 is 1.5 to 2.5.

The upper end of the filter material 200 is provided with a first water guiding ring 500, the first water guiding ring 500 corresponds to the source water inlet annular cavity 310, and the first water guiding ring 500 separates the waste water outlet annular cavity 320 from the source water space 110. A second water guiding ring 600 is arranged between the pure water outlet cavity 330 and the guide pipe 400, and the pure water outlet cavity 330 and the waste water outlet annular cavity 320 are separated by the second water guiding ring 600.

In operation, source water (e.g. tap water) passes through the source water inlet annular chamber 310 and then enters the source water space 110 through the first water guide ring 500, under the condition of high pressure of the booster pump, water molecules in the tap water permeate through the RO membrane of the filter material 200 and enter the conduit 400, and macromolecules such as minerals cannot permeate through the RO membrane, flow out along the filter screen in the filter material 200, and can permeate through the RO membrane to be pure water, and impurities which cannot permeate through the RO membrane are wastewater. Then, the waste water generated by filtering the source water by the filter material 200 passes through the space between the first water guide ring 500 and the second water guide ring 600 and is discharged through the waste water outlet annular cavity 320.

Because the machine stop work time, it has confined pressure to intake the end, and pure water end non-pressure, and intake the inside salt concentration of end and be higher than the pure water end, through the reverse osmosis principle, the concentrated solution of intaking the end can ooze the RO membrane, flows into the pure water end, because the pure water end is inside small, can lead to pure water end TDS (salt finished product) value to rise. The big inner diameter structure of pipe 400 of cooperation pure water end increases the volume of pure water end capacity volume, dilutes the TDS value to reach the salt concentration that reduces the pure water, promoted the desalination of the first glass of water of RO membrane.

Reference will now be made in detail to some embodiments, wherein "an embodiment" is referred to herein as a particular feature, structure, or characteristic that may be included in at least one implementation of the present application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Furthermore, the details representative of one or more embodiments are not necessarily indicative of any particular order, nor are they intended to be limiting.

In embodiment 1, referring to fig. 2, the first water guiding ring 500 includes a first water guiding ring upper ring 510 and a first water guiding ring lower ring 520, which correspond to the source water inlet annular cavity 310 and the outer side of the filter material 200, respectively, and can avoid secondary pollution by cooperating with the sealing rings. The second water guiding ring 600 includes a second water guiding upper ring 610 and a second water guiding lower ring 620, which correspond to the pure water outlet cavity 330 and the conduit 400, respectively, and can avoid secondary pollution by cooperating with the sealing rings.

Embodiment 2, referring to fig. 2, the first water guiding ring 500 and the second water guiding ring 600 are integrally formed, and a water through hole is formed between the first water guiding ring 500 and the second water guiding ring 600 to ensure that the filtered wastewater can enter the wastewater outlet annular chamber 320 and be discharged. This facilitates assembly of the filter cartridge.

A filter element comprises the structure capable of reducing the desalination rate of effluent. The running water passes through the filter core water inlet and gets into, under the highly compressed condition of booster pump, the inside hydrone of running water permeates in the hole entering pipe 400 on the RO membrane through central inner wall, the unable RO membrane of permeating of macromolecules such as mineral substance, along the inside filter screen outflow of the naked membrane of RO, it is the pure water to permeate the RO membrane, the impurity that can't permeate is waste water, because the machine stop work, the end of intaking has confining pressure, pure water end non-pressure, and the inside salt concentration of the end of intaking is higher than the pure water end, through the reverse osmosis principle, the concentrated solution of the end of intaking can permeate the RO membrane, the pure water end flows in, because the inside small of pure water end, can lead to pure water end salt finished product content to rise, the pipe 400 structure of cooperation pure water end, pure water end capacity volume, dilute salt finished product content, thereby reach and reduce pure water salt concentration, the desalination rate of the.

According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
