Problems solved by technology
It is easy to be clogged or the filtering effect is poor in the near future after a long time
Especially in areas with poor water quality, due to poor water quality and many impurities and pollutants, the ultrafiltration membrane needs to be replaced frequently, and the cost is high.
Because the traditional back flushing is flushing with tap water, it will also pollute the ultrafiltration membrane during flushing.

Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0035] Such as figure 1 , figure 2 As shown, a double-filter forward water filtration and reverse flushing system for a water purifier in this embodiment is characterized in that the double filter forward water filtration and reverse flushing system for a water purifier include:
[0036] A first filter element 1 and a second filter element 2 for drinking water filtration;
[0037] A first pipe connected to the bottom of the first filter element 1 and the bottom of the second filter element 2 for drinking water to enter;
[0038] A second pipe connected to the top of the first filter element 1 and the top of the second filter element 2 for filtering water to flow out;
[0039] And a third pipe connected to the bottom of the first filter element 1 and the bottom of the second filter element 2 for sewage to flow out;
[0040] The first pipeline is re...

The invention relates to a double-filter-element forward-filtering backward-flushing system for a water purifier and a using method. The system comprises a first filter element, a second filter element, a first pipeline, a second pipeline and a third pipeline, the first filter element and the second filter element are used for filtering drinking water, the first pipeline and the third pipeline areconnected with the bottoms of the first filter element and the second filter element, the second pipeline is connected with the tops of the first filter element and the second filter element, a firstelectromagnetic valve and a second electromagnetic valve are arranged on the first pipeline, and a third electromagnetic valve and a fourth electromagnetic valve are arranged on the third pipeline. Due to the above design, whole-room in-depth purifying is realized, and external-pressurizing filtering is adopted; water purifying and backward flushing are realized through pressure of tap water; backward flushing is adopted, so that service life of an ultrafiltration membrane is prolonged; secondary pollution and backward flushing pollution are avoided.
Description
technical field [0001] The invention relates to a flushing system and a use method for a water purifier, in particular to a forward water filtration and reverse flushing system and a use method with double filter elements for a water purifier. Background technique [0002] The filter element inside the water purifier cylinder is generally an ultrafiltration membrane, and water is filtered from one side of the ultrafiltration membrane to the other side. Bacteria and pollutants remain on the ultrafiltration membrane during the filtration process. It is easy to be blocked or the filtering effect is poor in the near future after a long time. Especially in areas with poor water quality, due to poor water quality and many impurities and pollutants, the ultrafiltration membrane needs to be replaced frequently, and the cost is high. Because the traditional back flushing is flushing with tap water, it will also pollute the ultrafiltration membrane during flushing. Contents of the...
