The invention discloses a disassembly-and-washing-free durable ceramic filter element water purifier which comprises a base 23, a ceramic filter element 1 and a non-magnetizer shell cylinder 3. The technical scheme is that a washing component is arranged in the shell cylinder 3 and is in mechanical linkage with an inner magnetic ring 2 which can slide along the shell cylinder 3, an outer magnetic ring 4 capable of sliding is sleeved outside the shell cylinder 3, and the two magnetic rings are separated by the cylinder wall and mutually absorbed. The outer magnetic ring 4 is pushed and rotated by hand, the inner magnetic ring 2 can be moved simultaneously and drives the washing component to wash the ceramic filter element 1, and sewage is discharged through a blowdown valve 24. Due to the fact that when the ceramic filter element 1 of the water purifier is washed, the outer cylinder 3 does not need to be disassembled, not only is operation convenient and fast, but also component damage possibly caused in the frequent washing and disassembling process is avoided, moreover, wearing strength imposed on the ceramic filter element by the washing component is reduced to the maximum, and active carbon which is inactive after a long time can be conveniently replaced, and therefore the service life of the water purifier can be greatly prolonged.
