Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and particularly relates to a wastewater ratio structure and a water purification device. Background Art

[0002] The wastewater ratio structure is an important component of a membrane filter element water purification device. When the water purification device is working, a part of the concentrated water in front of the membrane flows out from the wastewater ratio structure to prevent the concentration of the water in front of the membrane from being too high and affecting the performance of the water purification device. Due to different water quality conditions in different regions, the service life of the water purification device filter element is also different. Especially in some regions with high total dissolved solids (TDS) values and high hardness, the service life of the filter element will be greatly reduced due to the water quality. In order to adapt to this water quality situation, a larger wastewater ratio can be set to increase the service life of the filter element. However, such water purification products with a large wastewater ratio are not very suitable in other regions with relatively good water quality, resulting in waste of water resources. In the related art, it is usually achieved by setting wastewater ratio structures with different wastewater ratios for different regions, but this method will lead to too many product models. Moreover, the water quality difference within the same region is also relatively large, and a single wastewater ratio structure cannot meet the requirements. Summary of the Invention

[0052] In order to make the wastewater ratio structure meet different purification requirements, an embodiment of the present disclosure provides a wastewater ratio structure.

[0053] Figure 1 is a schematic diagram of a wastewater ratio structure shown according to an exemplary embodiment, asFigure 1 As shown in the figure, the wastewater ratio structure includes:

By setting the inner diameter of the second limiting groove 1012 to be smaller than that of the first limiting groove 1011, it can play a better limiting role on the end of the water inlet pipe and prevent the end of the water inlet pipe from moving.

[0072] In an alternative embodiment, the sealing structure 3 includes a second sealing ring 302.

[0073] In the embodiments of the present disclosure, the second sealing ring 302 is in a ring structure. Optionally, the second sealing ring 302 can be made of an elastic material such as rubber.

[0103] In a second aspect, the present disclosure also provides a water purification device including the above-mentioned wastewater ratio structure.

[0104] In an embodiment of the present disclosure, as Figure 7 shown, the water purification device includes a pre-filter element, a solenoid valve 1, a booster pump, a membrane filter element, and a post-filter element. The above components are sequentially connected in the water purification circuit. The water purification circuit also includes the above-mentioned adjustable wastewater ratio structure. By adjusting the rotating disc, the through hole is docked with different inner diameter conduit structures corresponding to different water inlet structures to control the water flow rate in the water purification circuit, and further realize the adaptive adjustment of the filtration of the total dissolved solids content value (TDS value) of different raw waters and the mineral retention rate.

[0105] In a specific embodiment, the implementation process of the technical solution in the embodiment of the present application is as follows:

[0106] Step 1: Save the relationship between the rotation gear of the wastewater ratio structure and the corresponding mineral retention rate to the system under preset different raw water TDS values;

[0107] Step 2: A technician detects the TDS value of the water at the installation location of the water purification device;

[0108] Step 3: Clearly inform the user of the relationship between the rotation gear of the wastewater ratio structure and the corresponding mineral retention rate, and let the user select the retention rate gear;

[0109] Step 4: Rotate to the corresponding target gear according to the TDS value and the retention rate gear selected by the user. For example, in the low TDS value area, a smaller wastewater ratio can be used, so as to achieve less wastewater volume, more energy saving and environmental protection, and moreover, the higher the mineral retention rate; in the high TDS value area, a larger wastewater ratio is used to increase the wastewater volume, aiming to reduce the ions in the produced purified water, prevent scaling when boiling water, and have a better taste (the mineral retention rate is reduced).

[0110] Those skilled in the art will readily conceive of other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein.
