Wherein, the bottom surface center of valve body 1 is connected with water pipe connector I11, thereby connects the water pipe through water pipe connector I11 and leads into the valve with water. The side of the valve body 1 is connected with water pipe connectors II12, III13, IV14 and V15. In this embodiment, the water pipe connectors II12, III13, IV14 and V15 are connected to the valve body 1 by screws, so as to facilitate the detachment and replacement of the water pipe connectors II12, III13, IV14 and V15, and also facilitate the cleaning in the valve body 1.

The valve core 2 is arranged in the valve body 1 and can rotate in the valve body 1 to realize the switching of three working conditions of filtering, washing and rinsing. And a sealing ring 4 is arranged between the valve core 2 and the water pipe connectors II12, III13, IV14 and V15 to enhance the sealing property of the valve.

Furthermore, the bottom of the valve core 2 is provided with a water inlet a21, and the water inlet a21 is communicated with the water pipe connector I1. And a through hole group b22, a through hole group c23 and a through hole group d24 are arranged on the periphery of the valve core 2. The side surface of the valve core 2 is spherical, and the through hole group b22, the through hole group c23 and the through hole group d24 are arranged on the spherical surface.

The water pipe connector I11 is communicated with the water inlet hole a 21. The through hole group b22 can be communicated with the water pipe connectors II12 and III 13; the through hole group c23 can be communicated with a water pipe connector IV 14; the through hole group d24 can be communicated with water pipe connectors II12, III12, IV14 and V15. Three partition plates 5 are arranged in the valve core 2, and the through hole group b22, the through hole group c23 and the through hole group d24 are separated by the three partition plates 5.
