Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water purification, in particular to a reverse osmosis water purification component and a water purifier. Background Art
[0002] Reverse osmosis (abbreviated as RO, English 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 opposite to the direction of 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. Thus, the permeated solvent is obtained on the low-pressure side of the membrane, which is the permeate; and the concentrated solution is obtained on the high-pressure side, which is the concentrate.
[0004] Using this reverse osmosis principle, people have manufactured water purifiers. The water purifier is provided with a reverse osmosis membrane filter element to perform reverse osmosis filtration on raw water to obtain pure water, and at the same time, concentrated water is discharged.

[0006] However, in the related water purification technology, after the water purification is completed, generally, the water purifier needs to be flushed. Since the pre-filter element or RO filter element is provided with a scale inhibitor, when the water purifier stops running, the concentrated water and the purified water will permeate bidirectionally, and the concentrated water containing the scale inhibitor will flow into the purified water. When the water purification is carried out again, the scale inhibitor will appear in the pure water, which affects the health of users. Summary of the Utility Model

[0052] Refer to Figure 1 and Figure 2, An RO water purification component provided by an embodiment of the present utility model, the component includes a booster pump 100, an RO unit 300, a flushing valve 400, a water inlet valve 500, and a scale inhibitor module 600.
[0053] Among them, the booster pump 100 has a pump inlet 110 and a pump outlet 120.
[0054] The RO unit 300 has an input end 310, a pure water output end 320, and a concentrated water output end 330. The input end 310 is communicated 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. Raw water enters from the booster pump 100, and after passing through 200, it can enter the RO unit 300 from the input end 310. After being filtered by the RO unit 300, the generated pure water is output from the pure water output end 320, and the generated concentrated water is output from the concentrated water output end 330.
[0055] The flushing valve 400 has a water inlet 410 and a water outlet 420. The water inlet 410 is connected to the raw water, and the water outlet 420 is connected to the pump inlet 110.
[0056] The water inlet valve 500 has a valve water inlet 510 and a valve water outlet 520, and the valve water inlet 510 is connected to the raw water.
[0057] The scale inhibitor module 600 has a scale inhibitor inlet 610 and a scale inhibitor outlet 620. The scale inhibitor inlet 610 is communicated with the valve water outlet 520, and the scale inhibitor outlet 620 is communicated with the pump inlet 110.
[0058] That is to say, a water inlet valve 500 and a scale inhibitor module 600 are arranged in series in front of the pump inlet 110 of the booster pump 100, and then the flushing valve 400 is arranged in parallel with the water inlet valve 500 and the scale inhibitor module 600 arranged in series.
[0059] When the water purification component performs water purification operations, the flushing valve 400 is closed, the water inlet valve 500 is opened, raw water can enter from the valve water inlet 510, after passing through the water inlet valve 500, it is output from the valve water outlet 520, then enters from the scale inhibitor inlet 610, after being subjected to scale inhibition treatment by the scale inhibitor module 600, it is output from the scale inhibitor outlet 620, and then successively passes through the booster pump 100, enters the RO unit 300 from the input end 310, and after being filtered by the RO unit 300, pure water is output from the pure water output end 320, and concentrated water is discharged from the concentrated water output end 330 to achieve water purification.
[0060] When the water purification component needs to be flushed, the flushing valve 400 is opened and the water inlet valve 500 is closed. Raw water can only enter from the water inlet 410, and after passing through the flushing valve 400, it is output from the water outlet 420. Then, it successively passes through the booster pump 100, enters the reverse osmosis unit 300 from the input end 310, and is discharged from the pure water output end 320 and the concentrated water output end 330 to achieve flushing.
[0061] It can be understood that for the reverse osmosis water purification component provided by the embodiments of the present utility model, by arranging the water inlet valve 500 and the scale inhibitor module 600 connected in series in front of the pump inlet 110 of the booster pump 100, and then arranging the flushing valve 400 in parallel with the water inlet valve 500 and the scale inhibitor module 600 connected in series; when the water purification component performs water purification operations, raw water can enter the booster pump 100 and the reverse osmosis unit 300 through the water inlet valve 500 and the scale inhibitor module 600 connected in series; when the water purification component needs to be flushed, raw water can only enter the booster pump 100 through the flushing valve 400, and the raw water for flushing can bypass the scale inhibitor module 600, so that the raw water entering the booster pump 100 and the reverse osmosis unit 300 for flushing does not contain scale inhibitor. Thus, when the water purification component purifies water again after flushing, there will be no scale inhibitor in the pure water, ensuring the health of users.
[0062] In some embodiments of the present utility model, the water purification component further includes a one-way valve 700 and a reflux valve 710 connected in series.
[0063] The one-way valve 700 has a one-way inlet 701 and a one-way outlet 702, and the reflux valve 710 has a flow inlet 711 and a flow outlet 712, and the flow outlet 712 is communicated with the one-way inlet 701.
[0064] The flow inlet 711 is communicated with the pure water output end 320, and the one-way outlet 702 is communicated with the pump inlet 110.
[0065] When the pressure of the pure water at the pure water output end 320 is too high, the reflux valve 710 is opened, and the pure water can flow into the booster pump 100 through the reflux valve 710 and the one-way valve 700, which can further pressurize the raw water and at the same time reduce the pressure of the pure water output from the pure water outlet of the water purification component.
[0066] In some embodiments of the present utility model, the water purification component further includes a TDS measuring device 800 and a flow meter 810. Among them, the TDS measuring device 800 is arranged on the connecting pipeline between the pure water output end 320 and the pure water outlet of the water purification component, and the flow meter 810 has a flow inlet 811 and a flow outlet 812.
[0067] The measuring inlet 801 is communicated with the pure water output end 320, and the measuring outlet 802 is connected to the pure water outlet of the water purification component.
[0068] The flow meter 810 is serially arranged with the TDS measuring device 800. The flow inlet 811 communicates with the pure water output end 320, and the flow outlet 812 communicates with the pure water port of the water purification assembly.
[0069] Of course, the TDS measuring device 800 can also be arranged on the connecting pipeline between the flow meter 810 and the pure water port of the water purification assembly.
[0070] Specifically, the TDS measuring device 800 is a Total Dissolved Solids, that is, a "total dissolved solids" measuring device, which can measure the total dissolved solids in the pure water obtained after being filtered by the reverse osmosis unit 300, so that users can judge the quality of the pure water and improve the intelligence level of the water purification assembly. The flow meter 810 can measure the output flow of the pure water, and users can accurately set the amount of purified water required each time, preventing the amount of purified water from being too much or insufficient, meeting the needs of users, and also avoiding the overwork of the reverse osmosis unit 300, thereby further extending the service life of the reverse osmosis unit 300.
[0071] In some embodiments of the present invention, the water purification assembly further includes a pre-filter 820 and a post-filter 830.
[0072] Among them, the pre-filter 820 is arranged at the front end of the flushing valve 400 or the water inlet valve 500, and the pre-filter 820 communicates with the water inlet 410 or the valve water inlet 510.
[0073] The post-filter 830 is arranged between the TDS measuring device 800 and the pure water port of the water purification assembly, and the post-filter 830 communicates the measuring outlet 802 with the pure water port of the water purification assembly.
[0074] When the raw water flows into the pre-filter 820, the pre-filter 820 can filter impurities such as sediment in the raw water and then input it to the water inlet valve 500 to protect the safety of each component of the water purifier.
[0075] When the pure water is output from the pure water output end 320 of the reverse osmosis unit 300, the post-filter 830 can adjust the taste of the pure water.
[0076] The pre-filter 820 and the post-filter 830 can be two independent filters. They can also be integrated into a composite filter. Of course, only one of the pre-filter 820 and the post-filter 830 can be provided to save manufacturing costs.
[0077] In some embodiments of the present invention, the water purification assembly further includes a check valve 840 and a high-pressure switch 850.

[0079] The high-pressure switch 850 is arranged between the check valve 840 and the pure water port of the pure water component.
[0080] When the pressure of the pure water output by the reverse osmosis unit 300 is too high, its pressure can be controlled by the high-pressure switch 850. The high-pressure switch 850 can also monitor the pressure of the output pure water, so as to timely control the opening or closing of the reflux valve 710, so that the pure water can flow back to the booster pump 100 to reduce the pressure.
[0081] An embodiment of the present utility model further provides a water purifier, which includes the reverse osmosis water purification component and the water purifier housing provided in the above-mentioned embodiment.
[0082] Among them, the reverse osmosis water purification component can be arranged in the water purifier housing to simplify the structure of the water purifier and facilitate the operation and use of the user for water purification.
[0083] It can be understood that a water purifier provided by the present utility model, due to including the above-mentioned reverse osmosis component, necessarily has all the advantages of this component. That is, in this water purifier, the raw water for flushing can bypass the scale inhibitor module 600, so that the raw water entering the booster pump 100 and the reverse osmosis unit 300 for flushing does not contain scale inhibitor. Thus, when the water purifier purifies water again after flushing, no scale inhibitor will appear in the pure water, ensuring the health of users.
