[0020] In the present embodiment, a dual ultrafiltration pipeline water purification structure is disclosed, which adopts two parallel first filter elements 1 and second filter elements 2, wherein the first filter element 1 has an inlet pipe 3 and an outlet pipe 4, and the second filter element 2 is connected in parallel with the first filter element 1, and the first filter element 1 and the second filter element 2 have the same filtering direction. During filtering, the first filter element 1 and the second filter element 2 can both be used as filtering units to filter water. After a long period of use, the first filter element 1 or the second filter element 2 will inevitably accumulate certain impurities, resulting in a decrease in filtering capacity. At this time, it is necessary to combine the first switch 5, the second switch 6 and the third switch 7 to backwash the first filter element 1 or the second filter element 2 to discharge sewage, thereby extending the service life of the filter element, reducing the replacement frequency, and improving the user experience.
[0021] Specifically, during normal water production, one of the first switch 5 and the second switch 6 is turned on, the first sewage outlet 8 and the second sewage outlet 9 are both closed, and the third switch 7 is turned on, then the water entering from the water inlet pipe 3 will be filtered and discharged from the water outlet pipe 4 for user use; when the first filter element 1 needs to be cleaned, the first switch 5 is closed, the second switch 6 is opened, the third switch 7 is closed, the second sewage outlet 9 is closed, and the first sewage outlet 8 is opened, and the first filter element 1 is backwashed with water filtered by the second filter element 2, and impurities are discharged from the first sewage outlet 8 to extend its service life.
