DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, the filter element device provided by the present invention includes a reverse osmosis membrane assembly 1, a bubbler 4 and a water supply assembly;

[0031] The water supply assembly is used to provide a gas-water mixture to the reverse osmosis membrane assembly 1. The reverse osmosis membrane assembly 1 includes a first water inlet 15 and a first water outlet. The water supply assembly is connected to the first water inlet 15. A partition 16 for cutting the gas-water mixture is provided between the first water inlet 15 and the first water outlet. The first water outlet includes a pure water outlet 12 and a concentrated water outlet 13.

[0032] The bubbler 4 includes a second water inlet and a second water outlet;

[0033] A first switch 22 for controlling opening and closing is provided at the pure water outlet 12; the concentrate water outlet 13 is connected to the second water inlet through the concentrate water flow limiting member 2, and a second switch 21 for controlling opening and closing is provided at the second water outlet.

[0034] The filtering method of the reverse osmosis membrane assembly 1 refers to the existing reverse osmosis filter element. The gas-water mixture provided by the water supply assembly enters from the first water inlet 15 and is cut at the partition 16 so that the components of the gas-water mixture are evenly mixed. The gas-water mixture enters the filter element through the partition 16, and a part of it enters the inner layer of the filter element under pressure, and flows out from the pure water outlet outlet 12 after sufficient filtration. The other part only enters the outer layer of the filter element and flows out from the concentrated water outlet outlet 13 after insufficient filtration. The impedance of the gas-water mixture in the inner layer of the filter element is greater than the impedance in the outer layer of the filter element. Therefore, when reverse osmosis water production is performed, it is necessary to limit the flow at the concentrated water outlet outlet 13 so that most of the gas-water mixture flows out from the pure water outlet outlet 12 through the inner layer of the filter element.

[0035] The filter element device in this scheme has a reverse osmosis water production mode and a microbubble water preparation mode. When in the reverse osmosis water production mode, the concentrated water flow limiting element 2 limits the concentrated water outlet 13, the first switch element 22 is opened, and the second switch element 21 is opened. After the gas-water mixture entering from the first water inlet 15 passes through the screen 16 and the filter element, most of the gas-water mixture flows out from the pure water outlet 12 due to the large impedance at the concentrated water outlet 13, so as to be utilized, and the other part with a smaller flow rate is discharged from the concentrated water outlet 13 as waste water;

[0036] When in the micro-bubble water preparation mode, the first switch 22 is closed and the second switch 21 is opened. The gas-water mixture entering from the first water inlet 15 passes through the partition 16 and the filter element. Since the pure water outlet 12 is closed, all the gas-water mixture flows out from the concentrated water outlet 13, passes through the bubbler 4, is made into micro-bubble water, and finally flows out from the second water outlet.

[0037] The traditional method of generating micro-bubble water requires high-pressure mixing in a special high-pressure resistant soda-water mixing tank before discharging, and limiting a certain flow rate can maintain high pressure in the mixing tank. This solution eliminates the micro-bubble water mixing tank, and uses the existing high-pressure resistant components of the reverse osmosis water purifier, such as the reverse osmosis membrane filter element 14, to change the original water flow path in the filter element, and use the high-precision spacer 16 inside the reverse osmosis membrane assembly 1 to form a cutting effect under high pressure and high flow rate, and cooperate with the bubbler 4 to form high-concentration micro-bubble water with the same effect.

[0038] The bubbler 4 in this scheme uses a microporous bubbler with a flow interception function, which can control the diameter of the water bubble to be kept at <80μm, forming a milky white gas-water mixture and controlling the flow rate at the same time.

[0039] In an optional embodiment, the reverse osmosis membrane assembly 1 includes a shell 10, a reverse osmosis membrane filter element 14 and a seal 11. The reverse osmosis membrane filter element 14 is located in the shell 10. There is a gap between the shell 10 and the reverse osmosis membrane filter element 14. The gap is respectively connected to the first water inlet 15 and the concentrated water outlet branch 13. The seal 11 is located in the gap, dividing the gap into a first cavity connected to the first water inlet 15 and a second cavity connected to the concentrated water outlet branch 13. The partition net 16 is located in the gap.

[0040] The outer ring surface of the reverse osmosis membrane filter element 14 is provided with a water inlet hole, and the spacer 16 is filled in the gap. The gas-water mixture needs to pass through the spacer 16 before entering the reverse osmosis membrane filter element 14 .

[0041] Compared with the traditional reverse osmosis filter element, the reverse osmosis membrane assembly 1 in this scheme has a spacer 16 added to the water inlet channel. The water flow port of the traditional reverse osmosis filter element enters from the water inlet on the end face of one side of the shell 10. Due to the obstruction of the sealing ring, the water flows into the filter element from the water inlet hole under the action of water pressure, passes through the inside of the reverse osmosis membrane, and the waste water that is not fully filtered is discharged from the concentrated water port on the other side of the end face. The filtered pure water is discharged from the central tube through the pure water port. There is some space in the gap between the reverse osmosis membrane and the membrane shell. In this scheme, a spacer 16 is set on the outside of the reverse osmosis membrane. The thickness of the spacer 16 allows it to fill the gap, and the spacer 16 is preferably one size smaller than the ordinary reverse osmosis membrane spacer 16, so as to achieve a better effect of cutting the gas-water mixture. Therefore, after the gas-water mixture enters the reverse osmosis filter element, the partition mesh 16 in the internal space of the reverse osmosis membrane and the partition mesh 16 in the gap of the outer membrane shell are cut, which achieves a better pressurized mixing effect, and finally, it is discharged from the concentrated water outlet 13 of the reverse osmosis membrane assembly 1.

[0042] The seal 11 is sleeved on the outer ring surface of the reverse osmosis membrane filter element 14 and fits with the inner wall of the shell 10 to achieve a sealing effect in the gap. After the gas-water mixture enters the shell 10, it flows along the first cavity toward the concentrated water outlet 13. Due to the presence of the seal 11, the gas-water mixture is blocked by the seal 11 and enters the reverse osmosis membrane filter element 14 under the action of water pressure. The filtration process of the gas-water mixture in the reverse osmosis membrane filter element 14 is consistent with that of the existing reverse osmosis filter element. A part of the gas-water mixture enters the inner layer of the filter element under pressure and flows out from the pure water outlet 12 after sufficient filtration. The other part only enters the outer layer of the filter element and flows out from the concentrated water outlet 13 after insufficient filtration. At the same time, a part of the concentrated water is retained in the second cavity.

[0043] In an optional embodiment, the shell 10 has a first end and a second end relative to each other; the first water inlet 15 is opened on the shell 10 near the first end, and the pure water outlet branch 12 and the concentrated water outlet branch 13 are opened on the shell 10 near the second end; the seal 11 is located in the gap near the second end.

[0044] Since a part of the gas-water mixture only enters the outer layer of the filter element, after passing through the seal 11, since the impedance in the second cavity is less than the impedance in the reverse osmosis membrane filter element 14, the gas-water mixture seeps out of the reverse osmosis membrane filter element 14 into the second cavity, and finally flows out from the concentrated water outlet 13, and a part of the concentrated water is retained in the second cavity. In order to avoid too much concentrated water being retained, the seal 11 is arranged in the gap near the second end in this scheme, so that the volume size of the second cavity is smaller, and therefore less concentrated water can be retained in the second cavity.

[0045] In an optional embodiment, the partition net 16 is located in the first cavity and the second cavity.

[0046] Since there is no partition in the gap in the existing reverse osmosis membrane assembly 1, and there is only a partition in the reverse osmosis membrane filter element 14, and since a part of the gas-water mixture only enters the outer layer of the filter element, the cutting effect of this part of the gas-water mixture is poor, so that the existing reverse osmosis membrane assembly 1 cannot effectively cut all the gas-water mixture entering its housing 10, so that the effect of producing microbubble water is poor. The partition 16 in this solution is located in the gap, especially is set in the first cavity and the second cavity at the same time, so that all the gas-water mixture entering the housing 10 from the first water inlet 15 can be cut at the partition 16.

[0047] In an optional embodiment, the water supply assembly includes an air pump 5 and a water delivery member, and both the air pump 5 and the water delivery member are connected to the first water inlet 15 .

[0048] The air pump 5 cooperates with the water delivery member to provide an air-water mixture.

[0049] Preferably, the water-gas ratio needs to be controlled in the range of (18:1) to (100:1), and the air intake flow rate needs to be controlled in the range of (25 to 110) ml / min.

[0050] The air pump 5 and the water delivery member are arranged in parallel, and a connecting pipe 20 is provided at the first water inlet 15. One end of the connecting pipe 20 is connected to the first water inlet 15, and the other end is divided into two openings, which are respectively connected to the air outlet of the air pump 5 and the water outlet of the water delivery member, so that the air provided by the air pump 5 and the raw water provided by the water delivery member are mixed in the connecting pipe 20. Under the action of the air pressure generated by the air pump 5, the air forms a stable air-water mixture with the raw water, and finally enters the reverse osmosis membrane filter element 14 through the first water inlet 15.

[0051] The water delivery device in this solution is an external water supply or other water storage equipment that can provide a certain water pressure.

[0052] In an optional embodiment, the water supply assembly further includes a booster pump 9 , the input port of the booster pump 9 is respectively connected to the air pump 5 and the water delivery member, and the output port of the booster pump 9 is connected to the first water inlet 15 .

[0053] The air pump 5 and the water delivery member are arranged in parallel, and a connecting pipe 20 is provided at the input port of the booster pump 9. One end of the connecting pipe 20 is connected to the input port of the booster pump 9, and the other end is divided into two openings, which are respectively connected to the air outlet of the air pump 5 and the water outlet of the water delivery member. The output port of the booster pump 9 is connected to the first water inlet 15 through the connecting pipe 20.

[0054] After the gas-water mixture enters the booster pump 9, it finally outputs a high-pressure and stable gas-water mixture from the output port under the boosting effect of the booster pump 9. The pressure generated by the booster pump 9 enables the gas-water mixture to pass through the partition 16 and enter the reverse osmosis membrane filter element 14 to complete the filtration.

[0055] The booster pump 9 can refer to the existing diaphragm booster pump 9 dedicated to the reverse osmosis system. Preferably, in this scheme, a booster pump 9 with an output working pressure of 90Psi and a flow rate of 3-4L is selected, wherein the inner cavity of the pump head is processed by flow channel optimization to adapt to the presence and final removal of a certain amount of air, and finally meet the requirements of high-pressure mixed gas water under different conditions such as continuity and intermittence, and can switch to the normal reverse osmosis membrane working state at any time.

[0056] In an optional embodiment, a pressure reducing valve 6 is provided between the water delivery member and the first water inlet 15 .

[0057] The pressure reducing valve 6 mainly plays the role of maintaining a constant pressure at the water inlet, and can stabilize the water pressure at 0.1 mPa, so that the gas-water mixture can stably and continuously pass through the isolation net 16.

[0058] In an optional embodiment, a first pipeline and a second pipeline are provided between the water delivery component and the first water inlet 15, the first pipeline and the second pipeline are arranged in parallel and are both connected to the first water inlet 15, the pressure reducing valve 6 is located on the first pipeline, and a fourth switch component 8 for controlling opening and closing is provided on the second pipeline.

[0059] The water delivery member is connected to the first water inlet 15 through the first pipeline and the second pipeline. The first pipeline and the second pipeline are arranged in parallel, that is, raw water can enter the first water inlet 15 through the first pipeline and the second pipeline at the same time, and can also enter the first water inlet 15 through the first pipeline or the second pipeline separately.

[0060] The fourth switch 8 is used to control the opening and closing of the second pipeline. When the filter element device is in the reverse osmosis water production mode, the fourth switch 8 is opened, and the raw water enters the first water inlet 15 from the first pipeline and the second pipeline at the same time. At this time, the flow rate of the raw water is relatively large, so after the pure water and waste water are separated in the reverse osmosis membrane filter element 14, the required amount of pure water can be obtained;

[0061] When in the micro-bubble water preparation mode, the fourth switch 8 is closed, and the raw water enters the first water inlet 15 from the first pipeline through the flow limiter of the pressure reducing valve 6. At the same time, with the cooperation of the air pump 5, the formed gas-water mixture is cut at the partition 16. Since the pure water outlet branch 12 is closed, all the gas-water mixture flows out from the concentrated water outlet branch 13, and then passes through the bubbler 4 to form micro-bubble water, and finally flows out from the second water outlet.

[0062] The water delivery member in this solution is connected to the booster pump 9 through the first pipeline and the second pipeline. At the same time, a connecting pipe 20 is provided at the input port of the booster pump 9, and the connecting pipe 20 is connected to the air outlet of the air pump 5, that is, the first pipeline, the second pipeline and the connecting pipe 20 for connecting the air pump 5 are arranged in parallel.

[0063] In an optional embodiment, the water delivery component includes a pre-filter element 7, the pre-filter element 7 has a fourth water inlet and a fifth water outlet, the fifth water outlet includes a first branch port 18 and a second branch port 19 connected in parallel to each other, a fifth switch component is provided on the first branch port 18, and the fourth branch port is connected to the first water inlet 15.

[0064] The pre-filter element 7 includes an ultrafiltration membrane, a PP filter layer, an activated carbon rod filter layer, etc. Several filter layers are combined into a primary filter element, or they can be separate multi-stage filter elements. The ultrafiltration membrane is a precision filter membrane with a pore size of 0.1-1 μm. The water passing through the pre-filter element 7 can be directly discharged from the third outlet for daily washing and cleaning of domestic water. The fourth switch 8 can be a faucet and a pipe used by the user in daily life to control the opening and closing of the third outlet.

[0065] The pre-filter element 7 may also not use an ultrafiltration membrane, and the PP filter layer and the activated carbon rod filter layer in the filter element may be shared, and can also be used for domestic water.

[0066] In an optional embodiment, the concentrated water flow limiting component 2 includes a third water inlet 17 and a third water outlet that are interconnected, the third water outlet includes a third branch port and a fourth branch port that are connected in parallel, the third water inlet 17 is connected to the concentrated water outlet branch port 13, the bubbler 4 is connected to the third branch port, and a third switch component 3 for controlling opening and closing is provided at the fourth branch port.

[0067] The third switch element 3 can be a solenoid valve, and the second switch element 21 can be a faucet used in daily life.

[0068] When the filter element device is in the reverse osmosis water production mode, the fifth switch element is closed, and the third switch element 3 is in the open state. At this time, the second switch element 21 at the second water outlet is closed, the first switch element 22 is opened, and the fourth switch element 8 is opened. The raw water enters the first water inlet 15 from the first pipeline and the second pipeline at the same time. After the gas-water mixture entering from the first water inlet 15 passes through the partition 16 and the reverse osmosis membrane filter element 14, due to the presence of the concentrated water flow limiting element 2 at the concentrated water outlet branch 13, the impedance of the concentrated water outlet branch 13 is relatively large. A part of the raw water enters the inner layer of the reverse osmosis membrane filter element 14 under pressure, and finally flows out from the pure water outlet branch 12, so as to be utilized. The other part of the raw water that has not entered the inner layer of the reverse osmosis membrane filter element 14 is discharged from the concentrated water outlet branch 13 as waste water;

[0069] When in the micro-bubble water preparation mode, the fifth switch is closed, the first switch 22 is closed, the fourth switch 8 is closed, and the third switch 3 is in the closed state. At this time, the second switch 21 at the second water outlet is opened, and the raw water enters the first pipeline through the limiting flow of the pressure reducing valve 6 and is mixed with the air input by the air pump 5 to enter the booster pump 9, and then enters the first water inlet 15. After the formed gas-water mixture is cut at the partition 16, since the pure water outlet branch 12 is closed by the first switch 22, all the gas-water mixture flows out from the concentrated water outlet branch 13, and then passes through the bubbler 4 to make micro-bubble water, and finally flows out from the second water outlet.

[0070] The first switch 22 and the second switch 21 in this solution can be integrated into a double water outlet faucet 23. There are two water outlet handles on the upper part of the double water outlet faucet 23, which respectively control the opening and closing of the pure water outlet 12 and the second water outlet of the bubbler 4. Among them, a Hall switch is arranged inside the double water outlet faucet 23. When one of the faucet handles is turned on, the water purifier function of the corresponding water path can be turned on through circuit electronic control, thereby providing corresponding water production.

Among them, a Hall switch is arranged inside the double-outlet faucet 23. When one of the faucet handles is turned on, the water purifier function of the corresponding water path can be turned on through circuit electronic control, thereby providing corresponding water production.
