<p>A flushing mechanism (100) includes a housing (1), an upper cover (6) on the housing (1), a sleeve (3), a first piston (4), a first piston sealing module (4-3), a first piston loading spring (5), a second piston (8) and a second piston loading spring (9). Wherein a pressure-relief and/or ejection-proofpart is provided in the housing (1), the second piston sealing module (8-3, 8-4) are respectively provided surround the periphery of the base end and the central hole of the second piston (8). The base end of the second piston (8), the second piston sealing module (8-3, 8-4) and the lower end of the housing (1) define an exterior lower cavity (8-5) and an interior lower cavity (8-6) used for cooperating with the second piston loading spring (9) in course of flushing, sequentially the second piston (8) is moved upward and the outlet is opened. A toilet bowl employing the flushing mechanism can reduce the flushing water consumption.</p> |
