Embodiment 1
[0058] Example 1: Please refer to figure 1 . A mechanical double faucet is added to this wastewater return system,
[0059] In this embodiment, the water purifier includes: a first reverse osmosis filter element 11a, a booster pump 12, a water outlet assembly 13, a first flow limiting valve 14a, a first switch valve 18a, a first one-way valve 15a, a first High pressure switch 16a, second high pressure switch 16b, second one-way valve 15b and third one-way valve 15c. The first reverse osmosis filter element 11a has the first water inlet 111, the first water outlet 112 and the first waste water outlet 113; It communicates with the first water inlet 111, and the first waste water port 113 communicates with one end of the first waste water straight discharge pipeline Q1; the water outlet assembly 13 has a water outlet 133, a drinking water inlet 131 and a domestic water inlet 132; the drinking water inlet 131 communicates with the first water outlet 112, and the domestic water ...
Embodiment 2
[0069] Example 2: Please refer to figure 2 . In this embodiment, on the basis of Embodiment 1, a pre-filter 17a is added at the front end of the booster pump 12. The type of the pre-filter 17a can be different forms of PP, different forms of activated carbon, ultrafiltration, nanofiltration and the above materials Composite filter elements, etc., the front outlet water flow rate is less than 8L / min.
[0070] The user turns on the drinking water faucet: the first high-pressure switch 16a detects a pressure change, starts the booster pump 12, and starts water production; the tap water is coarsely filtered by the pre-filter 17a and flows into the first reverse osmosis filter 11a, and is divided into one path of pure water and one path Wastewater and pure water are discharged from the drinking water faucet for drinking, and the waste water flows back to the booster pump 12 through the first restrictor valve 14a, mixes with the front effluent, enters the first reverse osmosis filte...
Embodiment 3
[0074] Example 3: Please refer to image 3 . In this embodiment, on the basis of Embodiment 1, a rear filter element 17b is added to the pure water outlet pipe of the first reverse osmosis filter element 11a, before the second check valve 15b and the first high pressure switch 16a. The species can be activated carbon in different forms.
[0075] The user turns on the drinking water faucet: the first high-pressure switch 16a detects a pressure change, starts the booster pump 12, and starts water production; after the tap water flows into the first reverse osmosis filter element 11a, it is divided into one path of pure water and one path of waste water, and the pure water passes through the rear filter element After 17b, it is discharged from the drinking water faucet for drinking, and the waste water is mixed with tap water before returning to the booster pump 12 through the first flow limiting valve 14a, and then enters the first reverse osmosis filter element 11a for further...
