Abstract: A flushing structure of a toilet and a toilet includes a main waterway, a jet waterway and a rim waterway. A main waterway inlet is in communication with an outlet on the toilet tank. A main waterway outlet is in communication with a jet waterway inlet and a rim waterway inlet. A jet waterway outlet is in communication with a jet hole beneath a water surface of a first water seal at the bottom of the toilet bowl. A rim waterway outlet is in communication with a rim hole provided on the toilet bowl for flushing the inner wall of the toilet bowl. A second water seal, whose water surface is on the same level with surface of the first water seal, is provided on the rim waterway. The main waterway and the jet waterway are isolated from air via the first water seal and second water seal.
