[0002] Reverse osmosis (abbreviated as RO in English, full name Reverse Osmosis) water purification refers to a membrane separation operation that uses a pressure difference as the driving force to separate the solvent from the solution. This membrane is a reverse osmosis membrane. Because it is in the opposite direction to natural osmosis, it is called reverse osmosis.

[0003] Apply pressure to the feed liquid on one side of the reverse osmosis membrane. When the pressure exceeds its osmotic pressure, the solvent will perform reverse osmosis against the direction of natural osmosis.

[0058] The following combination Figure 1 and Figure 4 , describes the embodiments of the present utility model. It should be understood that the following description is only a schematic implementation manner of the present utility model and does not constitute any limitation to the present utility model.

[0059] Refer to Figure 1 and Figure 4 , an embodiment of the present utility model provides a reverse osmosis water purification assembly, which includes a booster pump 100, a water inlet valve 200, a reverse osmosis unit 300, a breather 400, a prefilter 500, a flushing valve 600 and a return valve 700.

[0060] Among them, the booster pump 100 has a pump inlet 110 and a pump outlet 120.

[0061] The inlet valve 200 has a valve water inlet 210 and a valve water outlet 220, and the pump inlet 110 communicates with the valve water outlet 220.

[0062] The reverse osmosis unit 300 has an input end 310, a pure water output end 320 and a concentrated water output end 330; the input end 310 communicates with the pump outlet 120, the pure water output end 320 is connected to the pure water port of the water purification component, and the concentrated water output end 330 is connected to the concentrated water port of the water purification component.

[0063] The breather 400 communicates with the pump inlet 110.

[0064] The pre-filter 500 has an input port 510, an output port 520, a domestic water output port 530 and a flushing water output port 540; the input port 510 is connected to the raw water, and the output port 520 communicates with the valve water inlet 210.

[0066] The reflux valve 700 has a reflux inlet 710 and a reflux outlet 720, the reflux inlet 710 communicates with the pump outlet 120, and the reflux outlet 720 communicates with the output port 520 of the pre-filter 500;

[0067] When purifying water, both the flushing valve 600 and the reflux valve 700 are closed, both the inlet valve 200 and the booster pump 100 are opened. The raw water can enter the pre-filter 500 from the input port 510. After being filtered by the pre-filter 500, it enters the inlet valve 200 from the valve water inlet 210, is output from the valve water outlet 220 and then pressurized by the booster pump 100. After the raw water flows out from the pump outlet 120, it enters the reverse osmosis unit 300 from the input end 310. After being filtered by the reverse osmosis unit 300, the obtained pure water flows out from the pure water output end 320 to the pure water port of the water purification component, and the obtained concentrated water flows out from the concentrated water output end 330 to the concentrated water port of the water purification component. Of course, the reverse osmosis unit 300 can be an RO membrane, that is, a reverse osmosis membrane.

[0068] When flushing, the flushing valve 600, the reflux valve 700, and the booster pump 100 are all opened, the water inlet valve is intermittently opened, raw water can enter the pre-filter 500 from the input port 510. After being filtered by the pre-filter 500, due to the intermittent opening of the water inlet valve 200, raw water can enter the water inlet valve 200 from the valve water inlet 210, and after being output from the valve water outlet 220, it is pressurized by the booster pump 100. After the raw water flows out from the pump outlet 120, it enters the reflux valve 700 from the reflux inlet 710, and after flowing out from the reflux outlet 720, it enters the pre-filter 500 through the output port 520 to flush the pre-filter 500. The flushed water can enter the flushing valve 600 from the water inlet 610, and then is discharged to the flushing water outlet of the water purification assembly through the water outlet 620.

[0069] It can be understood that for the reverse osmosis water purification assembly provided by the embodiments of the present invention, by setting the reflux valve 700 and the flushing valve 600, connecting the reflux inlet 710 of the reflux valve 700 with the pump outlet 120 of the booster pump 100 and connecting the reflux outlet 720 of the reflux valve 700 with the output port 520 of the pre-filter 500, connecting the water inlet 610 of the flushing valve 600 with the flushing water output port 540 of the pre-filter 500 and connecting the water outlet 620 of the flushing valve 600 to the flushing water outlet of the water purification assembly; when flushing is required, the flushing valve 600, the reflux valve 700, and the booster pump 100 are all opened, the water inlet valve is intermittently opened, raw water can enter the pre-filter 500 from the input port 510. After being filtered by the pre-filter 500, due to the intermittent opening of the water inlet valve 200, the booster pump 100 can draw in air from the breather 400, so that the air is mixed with the raw water. The mixed raw water is pressurized by the booster pump 100 and then enters the reflux valve 700. After flowing out from the reflux outlet 720 of the reflux valve 700, it flushes the pre-filter 500 through the output port 520, and the impurities on the surface of the pre-filter 500 can be flushed up. Under the impact of the water flow, the impurities can be discharged from the flushing water outlet of the water purification assembly after passing through the flushing valve 600; after the pre-filter 500 of the water purification assembly is used, it is no longer easy to be blocked, the performance and service life of the pre-filter 500 can be improved, users no longer need to replace it frequently, and the use cost can be reduced.

[0070] In some embodiments of the present invention, the water purification assembly further includes a one-way valve 800 and a first reflux valve 810 arranged in series.

[0071] Among them, the one-way valve 800 has a one-way inlet 801 and a one-way outlet 802, the first reflux valve 810 has a flow inlet 811 and a flow outlet 812, and the flow outlet 812 is communicated with the one-way inlet 801.

[0072] The flow inlet 811 is communicated with the pure water output end 320, and the one-way outlet 802 is communicated with the pump inlet 110.

[0073] When the pure water pressure at the pure water output end 320 is too high, the first reflux valve 810 opens, and the pure water can flow into the booster pump 100 through the first reflux valve 810 and the check valve 800, further pressurizing the raw water and reducing the pressure of the pure water output from the pure water port of the water purification component at the same time.

[0074] In some embodiments of the present utility model, the water purification component further includes a wastewater valve 820.

[0075] The wastewater valve 820 has a wastewater inlet 821 and a wastewater outlet 822.

[0076] The wastewater inlet 821 is communicated with the concentrated water output end 330, and the wastewater outlet 822 is connected to the concentrated water port of the water purification component.

[0077] When water purification is required, the wastewater valve 820 opens. After the raw water is filtered by the reverse osmosis unit 300, the obtained concentrated water is discharged from the concentrated water output end 330, and then the concentrated water can flow into the concentrated water port of the water purification component from the wastewater inlet 821 through the wastewater valve 820 and thus be discharged to the outside.

[0078] When the water purification ends, the wastewater valve 820 closes.

[0079] Of course, when the pre-filter element 500 needs to be cleaned, both the wastewater valve 820 and the first reflux valve 810 are closed, stopping the reverse osmosis unit 300 from filtering, and all the raw water can enter the reflux valve 700, which can increase the flushing intensity for the pre-filter element 500.

[0080] In some embodiments of the present utility model, the water purification component further includes a first pre-filter element 830, and the first pre-filter element 830 has a filtering inlet 831 and a filtering outlet 832.

[0081] The first pre-filter element 830 is arranged between the pre-filter element 500 and the water inlet valve 200. The filtering inlet 831 is communicated with the output port 520, and the filtering outlet 832 is communicated with the valve water inlet 210.

[0082] After the raw water flows into the first pre-filter element 830, the first pre-filter element 830 can filter impurities such as sediment in the raw water and then input it to the reverse osmosis unit 300 to protect the safety of each component of the water purifier.

[0083] In some embodiments of the present utility model, the water purification component further includes a post-filter element 840, and the post-filter element 840 has an inlet 841 and an outlet 842.

[0084] The post-filter element 840 is arranged between the pure water output end 320 and the pure water port of the water purification component. The inlet 841 is communicated with the pure water output end 320, and the outlet 842 is connected to the pure water port of the water purification component.

[0085] After pure water is output from the pure water output end 320 of the reverse osmosis unit 300, the post-filter 840 can adjust the taste of the pure water.

[0086] Certainly, in some embodiments of the present invention, the first pre-filter 830 and the post-filter 840 can be composite filters, which can simplify the structure of the water purification component and save manufacturing costs.

[0087] Specifically, the pre-filter 500 can be a UF filter or a PP cotton filter to further improve the lifespan of the pre-filter 500.

[0088] To prevent the purified pure water from flowing back into the post-filter 840, in some embodiments of the present invention, the water purification component further includes a check valve (not shown in the drawings).

[0089] The check valve has a check inlet and a check outlet. The check inlet is connected to the post-filter 840, and the check outlet is connected to the pure water port of the water purification component.

[0090] An embodiment of the present invention further provides a water purification system, which includes the reverse osmosis water purification component and a control member (not shown in the drawings) provided in the above embodiment.

[0091] The control member is electrically connected to the booster pump 100, the inlet valve 200, the flushing valve 600, and the return valve 700 to control the opening and closing states of the booster pump 100, the inlet valve 200, the flushing valve 600, and the return valve 700, making the water purification system more intelligent and improving the water purification efficiency.

[0092] Since the water purification system includes the reverse osmosis component of the above embodiment, it necessarily has all the advantages of this component. That is, when the water purification system needs to be flushed, under the impact of water flow, impurities in the pre-filter 500 can be discharged from the flushing water port of the water purification component; after the pre-filter 500 of the water purification system is used, it is no longer easy to be blocked, which can improve the performance and service life of the pre-filter 500, and users no longer need to replace it frequently, reducing the usage cost.

[0093] An embodiment of the present invention further provides a water purifier, which includes the water purification system of the above embodiment and a water purifier housing (not shown in the drawings).

[0094] Among them, the reverse osmosis water purification system is arranged in the water purifier housing.

[0095] Since the water purifier includes the water purification system of the above embodiment, it necessarily has all the advantages of this system. That is, when the water purifier needs to be flushed, under the impact of water flow, impurities can be discharged from the flushing water outlet of the water purifier; after the pre-filter 500 of the water purifier is used, it is no longer prone to clogging, which can improve the performance and service life of the pre-filter 500.
