Automatically sanitized toilet seat incorporating means for collecting the sanitized fluid

A toilet seat (1) for association with a toilet bowl (2), said seat having a generally ring-shaped structure with an upper surface (1a) coming into contact with a user, said surface (1a) being defined between an external perimeter edge (1b) and an internal perimeter edge (1c), said seat (1) comprising or being associated with a multiplicity of spray nozzles (4) for moistening said upper surface with sanitizing fluid, said seat (1) comprising a passage (6) formed so as to provide a fluid inlet opening along the external perimeter edge (1b) and a fluid outlet opening along the internal perimeter edge (1c), said inlet opening being shaped in such a manner as to collect the excess fluid flowing over said external edge (1b), whereby said excess fluid is drained away into the toilet bowl (2) through said passage (6) and its outlet opening, said passage (6) being defined by an upper part (11) and a lower part (12) that are mutually connected in a spaced manner, said lower part (12) being provided with an external perimeter lip (12a) that is bent obliquely upwards, characterized in that said upper part (11) is correspondingly provided with an external perimeter lip (11a) that is bent obliquely downwards and inwards, spaced from said lip (12a) on the lower part (12) so as to form said inlet opening of said passage (6), whereby said excess fluid, adhering to the surface of said external lip (11a) of the upper part (11), enters said passage (6), dropping said external lip (12a) of the lower part (12).
