A ring groove is arranged at the end face of the main opening of the water filter housing, and the sealing ring embedded in the ring groove has a unique sealing effect. The sealing ring is close to the inner wall of the upper cover, and plays a sealing role between the water filter housing and the end cover.The sealing ring can be embedded in the outer wall of the main body of the water filter housing before the assembly of the water filter housing and the upper cover, and because the sealing ring has certain elasticity, it can be tied in the ring groove, so the sealing ring will not be displaced, the assembly is very convenient, and the sealing performance is improved at the same time.
