A device for automatically flushing toilet bowls is disclosed. The device has a toilet seat (5). The toilet seat (5) is provided with a pressure chamber (7) so as to discharge air in the chamber (7) when the chamber (7) is compressed and to return air into the chamber (7) when the chamber (7) is free from the pressure. A rotating lever (24) is hinged in a mounting slot (21) of the opening and shutting lever (19) and is rotatable in a vertical plane. A manipulating rod (17) has a hook (18) at its end and is communicated with the pressure chamber (7) of the toilet seat (5) so that the hook (18) of the manipulating rod (17) selectively pushes and pulls the upper end of the rotating lever (24) while moving forward or moving backward. A guide rod (25) is fixed to a side of the opening and shutting lever (19) at its upper end and is extended downward. A float (26) is movably set around the guide rod (25) through a vertical inserting hole (27) so as to be guided by the guide rod (25), is provided with a guide slit (28) at its upper portion and is connected to the shutoff valve (4) by means of a connecting string (30), the vertical inserting hole (27) being extended to the guide slit (28). |
