Description

Technical Field

[0001] The utility model relates to the technical field of water purification, in particular to a filter element structure with a scale inhibitor module and a water purification system. Background Art

[0002] Generally, filter materials such as scale inhibitors in existing water purification devices are added to the activated carbon in a composite filter element and integrally formed, or the scale inhibitor is added to the front end of the RO filter element and needs to be replaced together with the RO filter element.

[0003] This leads to the problem that when applied to a water purifier with dual water outlets, the water quality of the domestic water end may not meet the standard due to the slow release of the scale inhibitor component.

[0004] In the water purification device where the scale inhibitor is added to the front end of the RO filter element, the service life of the RO membrane is long. In the middle and late stages of its service life, the scale inhibitor has been released completely and cannot play the role of scale inhibition, affecting the service life of the RO membrane.

[0005] Therefore, how to solve the problem that the water quality of the domestic water end does not meet the standard on the premise of effectively protecting the long service life of the RO membrane has become a technical problem that needs to be solved urgently by those skilled in the art.

[0009] Preferably, the scale inhibitor module, the three-way valve, the PP cotton activated carbon module and the domestic water pipeline are integrated in a housing.

[0010] Preferably, the three-way valve is an electromagnetic valve or a mechanical valve.

[0011] The invention also provides a water purification system, which includes the above-mentioned filter element structure with a scale inhibitor module;

[0012] The inlet of the PP cotton activated carbon module of the filter element structure is connected to tap water, and the outlet of the scale inhibitor module is successively connected to a booster pump, an RO filter element, a check valve, and a CB filter element.

[0013] Preferably, when the three-way valve is a mechanical valve, a high-pressure switch is connected through a three-way connection on the pipeline between the check valve and the CB filter element.

[0014] Preferably, when the three-way valve is an electromagnetic valve, there is no need to connect a high-pressure switch.

[0015] Preferably, a waste water solenoid valve is provided at the waste water outlet of the RO filter element.

[0016] Advantages of the present utility model:

[0021] Embodiment 1

[0022] As Figure 1 shown, a filter element structure with a scale inhibitor module includes a scale inhibitor module 1, a three-way valve 2, a PP cotton activated carbon module 3, and a domestic water pipeline 4.

[0023] Among them, the inlet of the three-way valve 2 is connected to the PP cotton activated carbon module 3, and the two outlets are respectively connected to the scale inhibitor module 1 and the domestic water pipeline 4, forming a first waterway for connecting the PP cotton activated carbon module 3 and the domestic water pipeline 4, and a second waterway for connecting the PP cotton activated carbon module 3 and the scale inhibitor module 1.

[0024] In some embodiments, the scale inhibitor module 1, the three-way valve 2, the PP cotton activated carbon module 3, and the domestic water pipeline 4 are integrated in a housing.

[0025] In practical applications, the scale inhibitor module 1 can be installed alone as a filter element, or integrated with a three-way valve 2, a PP cotton activated carbon module 3, and a domestic water pipeline 4 into a housing to form a composite filter element, with a first water path and a second water path formed inside the composite filter element.

[0026] The scale inhibitor module 1, the three-way valve 2, the PP cotton activated carbon module 3, and the domestic water pipeline 4 integrated in a housing, where the water outlet of the PP cotton activated carbon module 3 is divided into two paths by the three-way valve 2, leading to the domestic water pipeline 4 and the scale inhibitor module 1 respectively, and the water outlet of the domestic water pipeline 4 is connected to the domestic water end faucet; the water outlet of the scale inhibitor module 1 is sequentially connected to a booster pump 6, an RO filter element 7, a check valve 8, and a CB filter element 9 to form a pure water water path.

[0027] Among them, the arrangement of the scale inhibitor in the scale inhibitor module 1 and the internal channels can be flexibly adjusted according to the actual slow release effect and water flow efficiency.

[0028] In some embodiments, the three-way valve 2 is a mechanical valve.

[0029] As Figure 2 shown, the present invention also provides a water purification system, including the above-mentioned filter element structure 5 with a scale inhibitor module;

[0030] The inlet of the PP cotton activated carbon module 3 of the filter element structure 5 is connected to tap water, and the outlet of the scale inhibitor module 1 is sequentially connected to a booster pump 6, an RO filter element 7, a check valve 8, and a CB filter element 9.

[0031] In practical applications, the scale inhibitor module 1 in the above structure can prevent calcium and magnesium ions from combining with carbonate ions in water to form precipitates on the raw water and wastewater sides of the RO membrane of the RO filter element 7, preventing blockage of the RO membrane.

[0032] Therefore, it can be ensured that the scale inhibitor in the scale inhibitor module 1 is only consumed when passing through the RO filter element 7, which can effectively protect the RO membrane of the RO filter element 7 and solve the problem of unqualified water quality of the outlet water.

[0033] In some embodiments, a high-pressure switch 11 is connected through a three-way on the pipeline between the check valve 8 and the CB filter element 9.

[0034] In some embodiments, a wastewater solenoid valve 10 is provided at the wastewater outlet of the RO filter element 7.

[0035] Embodiment 2

[0036] As Figure 2 shown, the water inlet of the PP cotton activated carbon module 3 is connected to the tap water source. After being filtered by the PP cotton activated carbon module 3, the water outlet is connected to the domestic water end faucet of the domestic water pipeline 4 through a three-way valve 2.

[0037] The water path after the scale inhibitor module 1 includes a pure water path and a waste water path. The outlet of the scale inhibitor module 1 is sequentially connected to a booster pump 6, an RO filter element 7, a check valve 8, and a CB filter element 9.

[0038] When the user opens the faucet at the water-using end of the domestic water pipeline 4, only passing through the PP cotton activated carbon module 3 can complete the preliminary filtration and meet the domestic water demand.

[0039] When the user opens the pure water end, the high-pressure switch 11 is activated. The tap water passes through the scale inhibitor module 1, the booster pump 6, the RO filter element 7, the check valve 8, and the CB filter element 9, and finally reaches the pure water faucet to meet the user's drinking water demand.

[0040] During use, when the faucet at the water-using end of the domestic water pipeline 4 is opened, the tap water passes through the PP cotton activated carbon module 3 and reaches the domestic water faucet through the three-way valve 2.

[0041] When the pure water faucet is opened, the high-pressure switch 11 starts to work. The three-way valve 2 inputs the water output into the scale inhibitor module 1. Under the action of the booster pump 6, the tap water passes through the PP cotton activated carbon module 3, the three-way valve 2, and the scale inhibitor module 1, so that the scale inhibitor in the scale inhibitor module 1 is slowly released with the water flow, achieving the purpose of protecting the RO membrane in the RO filter element 7 and the booster pump 6. The water passing through the scale inhibitor module 1 is then treated by the RO filter element 7 and the CB filter element 9 to produce pure water, which reaches the pure water faucet.

[0042] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning, or limited experiments based on the concept of the present invention on the basis of the prior art should be within the protection scope determined by the claims.
