The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The first embodiment is as follows:
as shown in fig. 1, the water purification system of the present embodiment includes a first filtering structure 10, a water purification branch 20, a waste water branch 30, and a flow restriction structure 40. Wherein, the water purification branch 20 and the waste water branch 30 are both connected with the first filtering structure 10 and located at the downstream position of the first filtering structure 10. The flow restriction structure 40 is disposed on the clean water branch 20.
Utilize the technical scheme of this embodiment, the user is when getting the water, and water purification branch 20 receives the influence of current-limiting structure 40, and the flow of the residual water that begins to flow out reduces, and then prolongs the time that the residual water flows out. In the time of extension, pressurization is accomplished to first filtration 10 to make water purification system follow-up can go out water in succession, consequently eliminated the condition that has the cutout when getting water, promoted user's use experience greatly. Therefore, the technical scheme of the embodiment overcomes the defect of poor use experience of the water purifier user in the prior art.
As shown in fig. 2, in the solution of the present embodiment, the flow restriction structure 40 is a relief valve 41. Specifically, the relief valve 41 described above functions such that when a user takes water, the residual water flows out from the water purification branch 20, and the pressure of the residual water opens the relief valve 41. However, the pressure relief valve 41 does not fully open the clean water branch 20, but only partially, thereby providing a flow restriction effect for the clean water branch 20. Due to the flow limiting effect, the flow of the residual water is reduced, and further the prolonging time of the residual water is prolonged. During the above-mentioned extended time, the first filtering structure 10 completes pressurization, so that the purified water branch 20 can continuously discharge water subsequently, thereby eliminating the situation of water taking and water blocking.
As shown in fig. 3 and 4, in the present embodiment, the relief valve 41 includes a first valve body 411, a first valve spool 414, and a first elastic member 415. Wherein the first valve body 411 has a first water inlet 412 and a first water outlet 413. The first valve spool 414 is movably disposed within the first valve body 411. The first elastic member 415 is disposed inside the first valve body 411 and applies an elastic force to the first valve spool 414 in a direction toward the first water inlet 412, wherein a flow-passing gap 416 is provided on a sidewall of the first valve spool 414.
Specifically, as can be seen from fig. 3, the lower end of the first valve spool 414 is provided with a sealing rubber block, and when the pressure of the first water inlet 412 is less than a preset value, the first valve spool 414 closes the first water inlet 412 under the action of the elastic force of the first elastic member 415. When a user takes water, the pressure of the residual water makes the first valve core 414 move upward, so that a gap is formed between the lower end of the first valve core 414 and the first water inlet 412, and the residual water flows into the first valve body 411. As can be seen from fig. 4, the outer side wall of the first valve spool 414 is provided with a plurality of flow-passing clearances 416 extending in the axial direction of the first valve spool 414. Therefore, when the residual water flows into the first valve body 411, the residual water flows to the first water outlet 413 along the flow gap 416. Obviously, the cross-sectional area of the plurality of flow gaps 416 is smaller than the cross-sectional area inside the first valve body 411, so that the remaining water is restricted. Therefore, the residual water is drained after a certain delay time, and the first filtering structure 10 is pressurized, so that the subsequent pure water branch 20 can be drained continuously and stably, thereby eliminating the phenomenon of drainage and flow interruption.
As shown in fig. 1, in the solution of this embodiment, the water purification system further includes a first switch structure 50 disposed on the water purification branch 20, and the flow limiting structure 40 is located at an upstream position or a downstream position of the first switch structure 50. Specifically, the first switch structure 50 is a pressure switch, and is used for starting the water purification system to produce water. Further, the end of the water purification branch 20 is connected with a faucet. When the user opens the tap, the pressure switch detects the pressure reduction in the water purification branch 20, and then starts the water purification system to make water. In this embodiment, the current limiting structure 40 is located at a downstream position of the first switch structure 50, but it is also possible to implement the current limiting structure 40 at an upstream position of the first switch structure 50.
As shown in fig. 1, in the present embodiment, the first filtering structure 10 is a reverse osmosis membrane filter element. Specifically, the raw water passes through the reverse osmosis membrane cartridge, and the reverse osmosis membrane cartridge is pressurized, and then the filtered clean water is discharged from the clean water branch passage 20, and the filtered concentrated water (wastewater) is discharged from the wastewater branch passage 30. Preferably, a waste water solenoid valve is disposed on the waste water branch 30.
As shown in fig. 1, in the technical solution of the present embodiment, the water purification system further includes a raw water branch 60, the raw water branch 60 is connected to the first filtering structure 10 and is located upstream of the first filtering structure 10, and a second switch structure 70 and a booster pump 80 are sequentially disposed on the raw water branch 60 along a water inlet direction. Specifically, the second switching structure 70 is an electromagnetic valve and is used to control the raw water to flow into the raw water branch 60. The booster pump 80 is used to pressurize the first filtering structure 10 (reverse osmosis membrane cartridge) described above, so that the first filtering structure 10 can filter raw water.
As shown in fig. 1, in the technical solution of the present embodiment, the water purification system further includes a second filter structure 90 and a third filter structure 100, the second filter structure 90 is disposed on the raw water branch 60, and the third filter structure 100 is disposed on the water purification branch 20. The second filter structure 90 is a front filter element, and the third filter structure 100 is a rear filter element.
Further, as can be seen from the above description, the raw water passes through the second filtering structure 90, then the first filtering structure 10, and finally the third filtering structure 100. Therefore, the second filtering structure 90 in this embodiment is a first filtering structure, the first filtering structure 10 is a second filtering structure, and the third filtering structure 100 is a third filtering structure.
As shown in fig. 1, in the solution of the present embodiment, the second filter structure 90 and the third filter structure 100 are an integral structure. Wherein, second filter structure 90 and third filter structure 100 are located integrative PCU composite filter core. Of course, embodiments are possible in which the second filter arrangement 90 and the third filter arrangement 100 are two separate filter cartridges.
The embodiment also provides a water purifier, wherein the water purifier comprises a water purification system, and the water purification system is the water purification system. The purifier of this embodiment does not have the condition of water intaking cutoff when the start-up, and then greatly increased user's use experience.
Example two
As shown in fig. 5 to 7, the second embodiment of the water purification system is different from the first embodiment in that the flow restriction structure 40 is a pressure reducing valve 42.
As shown in fig. 5 to 7, in the solution of the present embodiment, the pressure reducing valve 42 includes a second valve body 421, a second valve spool 424, and a second elastic member 425. Wherein, the second valve body 421 has a second water inlet 422 and a second water outlet 423. The second spool 424 is movably disposed in the second valve body 421. The second elastic member 425 is provided in the second valve body 421 and applies an elastic force to the second spool 424 in a direction toward the second outlet 423. Further, the second spool 424 is provided with a flow passage port 426, and the flow passage port 426 communicates between the upstream side and the downstream side of the second spool 424.
Specifically, as can be seen from fig. 6 and 7, when the residual water flows in from the second water inlet 422, the residual water can flow to the second water outlet 423 along the overflow port 426 of the second valve spool 424 because the second valve spool 424 is provided with the overflow port 426 penetrating upstream and downstream thereof. Further, when the residual water pressure is higher, the pressure of the water flow exerts an upward reaction force on the second valve spool 424, so as to push the second valve spool 424 to move upward, thereby limiting the flow rate of the second water inlet 422. Therefore, the residual water is drained after a certain delay time after the effect of limiting the flow, and the first filtering structure 10 is pressurized in the delay time, so that the subsequent pure water branch 20 can stably and continuously drain water, thereby eliminating the phenomenon of draining and breaking off the flow.
Compared with the water purification system of the first embodiment, the water purification system of the second embodiment has the same structure as the first embodiment except for the difference of the flow limiting structure 40, and thus, the description thereof is omitted.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
