Non-contact driving magnetic suspension nutation blood pump

The utility model relates to a non-contact driving magnetic suspension nutation blood pump which comprises a shell with a fluid containing cavity and a nutation mechanism. The nutation mechanism divides the fluid containing cavity into a first cavity and a second cavity, the nutation mechanism comprises a nutation disc, a magnetic suspension component and a driving component, and the nutation discswings relative to the fluid containing cavity to change the sizes of the first cavity and the second cavity; the magnetic suspension component comprises two hemispherical shell magnets on the upperside and the lower side of the nutation disc, inner magnetic assemblies embedded in the two hemispherical shell magnets respectively and outer magnetic assemblies, and the magnetism of the outer magnetic assemblies is opposite to that of the inner magnetic assemblies. The driving member includes: a rotating assembly rotatably supported on the housing; the plurality of fan-shaped magnet blocks arearranged at the peripheral
