The utility model uses the self pressure of the water purifier to back flush the pretreatment filter element, can wash away the impurities trapped on the surface of the pretreatment filter element, and achieves the self-cleaning function. The patent can automatically back flush the water purifier, but the device has a complex structure.
Chinese patent application CN202011538851.3 discloses a water purifier waterway system capable of back flushing, wherein a first cavity of the composite filter element is provided with a first filter module, and a second cavity is provided with a second filter module and an air bag; the primary filtering branch is connected with the primary filtering water inlet and the water inlet end of the RO membrane filter element; the secondary filtering branch is connected with the water outlet end of the RO membrane filter core and the pure water inlet; the water outlet pipe is connected with the water purifying outlet and the water taking device; the water inlet valve is arranged on the primary filtering branch; the supercharging device is arranged on the primary filtering branch; the reverse osmosis check valve is arranged on the secondary filtering branch; the reverse osmosis check valve is used for forward conduction and reverse throttling; the air bag is used for providing pressure for the second containing cavity when the water taking device is closed, so that water in the second containing cavity reversely flows into the RO membrane filter core through the secondary filtering branch and washes the RO membrane filter core. The utility model can timely carry out back flushing on the RO membrane, thereby avoiding the problem of higher TDS value of the first-stage effluent after long-time standby and effectively prolonging the service life of the RO membrane filter element. However, the utility model needs to use structures such as an air bag, a pressurizing device and the like, so that the water path system of the water purifier capable of back flushing has a complex structure.
Accordingly, there is a need in the art for a new disassembly-free backwash water purification system.
