Magnetic foot spa with rotating drive hub and pump
A recently granted patent (Publication Number: US11951069B2) discloses a unique spa design that includes a basin for water containment, a motor with a rotating element and magnetic properties, and a pump with an impeller featuring a ferromagnetic first portion and a non-ferromagnetic second portion. The impeller is designed to draw water through an intake and eject it through ports, with the rotation of the impeller being driven by the magnetic field generated by the motor's drive hub. The specific dimensions and materials of the impeller components are also detailed in the patent claims.
Furthermore, the patent claims specify additional features of the spa, such as the composition of the ferromagnetic first portion of the impeller (steel), the non-ferromagnetic second portion (aluminum), and the dimensions of each portion. The design includes a set of angled blades on the impeller, with specific measurements provided for the area, diameter, length, height, and taper angle of each blade. The patent also outlines the arrangement of the blades at a particular angle to the impeller's radius. Additionally, the intake of the pump is described to have cut-aways, and the number of blades in the impeller set is specified. These detailed claims provide a comprehensive overview of the innovative spa design covered by the patent.
