Patent ID: 11885148

Abstract:
A pool aerator for pools with water recirculation circuit includes a hemispherical body and an atmospheric air intake pipe. The body of the aerator includes a rounded plastic object, having in the middle area a cylindrical portion, and at one end with a connecting means to the pool nozzle. The middle portion of the aerator body continues with a hemispherical dome. A Venturi tube made in the form of two intersected frustoconical spaces is positioned in the hemispherical dome. One of the intersected frustoconical spaces functions as an inlet and the other for mixing and discharging water mixed with air. The two axes of the intersected frustoconical spaces form an angle (α) between 10 and 20 degrees. The mixing hole communicates with a vertical cylindrical hole, in which the intake pipe is inserted by sliding, until the inner wall of the frustoconical hole is reached.
