Claim 6:
7. A hemispherical pool aerator provided with a water recirculation circuit comprising:
a spray body made in a form of a Venturi tube and an atmospheric air intake pipe, wherein:
the body of the aerator includes a rounded plastic object, having in a middle portion a cylindrical portion, which includes an end connected with a pool wall with a connecting means, corresponding to an outlet used for evacuating water recirculated in the pool,
the middle portion of the aerator body continues with an area in a form of a hemispherical cap, inside the aerator body, being the Venturi tube made in a form of two frustoconical holes with a common base,
one of the frustoconical holes functions as an inlet and the other of the frustoconical holes functions for mixing and discharging water mixed with air,
a first frustoconical inlet hole is located between the connecting means having a horizontal axis and a second frustoconical mixing hole,
the second frustoconical mixing hole located in the middle of the connecting means and a spherical portion of the aerator body, having a longitudinal axis inclined in relation to the horizontal axis of the frustoconical inlet hole at an angle («) between 10 to 20 degrees, and
the second frustoconical mixing hole communicates in a first third from the common base with a cylindrical hole having a vertical axis, in which a lower end of the intake pipe is configured to slide, until an inner wall of the frustoconical mixing and discharge hole is reached.
