The invention discloses a water purifier with a filter core backflushing pressure relief function. The water purifier with the filter core backflushing pressure relief function comprises a water inletball valve, a first electromagnetic valve, a booster pump, a filter core assembly and a second electromagnetic valve which are sequentially connected, and further comprises a third electromagnetic valve and a check valve assembly, wherein the water inlet ball valve is connected with a tap water pipe; the second electromagnetic valve is connected with a tap; a first flushing pressure relief port is formed in the filter core assembly; a second water inlet and a second flushing pressure relief port are formed in the third electromagnetic valve; the second water inlet is connected with the firstflushing pressure relief port; the check valve assembly is arranged between the third electromagnetic valve and the filter core assembly. The using efficiency of the filter core assembly is improved,the usage rate of the filter core assembly is increased better through backflushing of the filter core assembly, and the service life of the water purifier is prolonged.
Description
technical field [0001] The invention relates to the technical field of water purifiers, in particular to a water purifier with the backwashing and pressure relief function of a filter element. Background technique [0002] The water purifier is a water treatment equipment that performs deep filtration and purification treatment of water quality according to the requirements of water use. [0003] The water purifier in the prior art only has a filtering function. With the long-term use of the water purifier, there will be impurities accumulated in the filter element of the water purifier, which makes the filter element filter insufficient, reduces the filtering effect of the filter element, and also causes damage to the filter element. Certain damage shortens the service life of the water purifier. Contents of the invention [0004] Aiming at the above-mentioned problems that the existing water purifiers will cause damage to the filter element during long-term use and shor...
