摘要

Drain and drain cleaning device comprising between the initial tubular section with an initial end (11) and the siphon (12) a mechanism (2) for opening and closing the flow passage comprising a central tubular section (22) of larger diameter than the initial tubular section (11), a floating element (21) located inside the central tubular section (22) that in the rest position allows the flow between the initial section (11) and the siphon (12), an orifice (23) in the tubular section (22) in whose opening is connected, by means of a flexo (3), a flow inlet from the sanitary water network in such a way that when there is a siphon jam that impedes the flow to through it, the pressurized water that penetrates through the orifice (23) drives the floating element (21) upwards (blocking position), plugging the initial section of the drain conduit (11) and preventing the domestic water from returning to the water. sink (5) and, at the same time, pushes, with the force of the pressure axis Any residual traces of any other section of the drainage pipe (1), especially the siphon (12).
