    摘要: A portable electric fan including a base having an upwardly directed coupling surface and a bottom surface for mounting on a foundation; a support having a downwardly directed coupling surface rotatably mounted on the upwardly directed coupling surface; a housing fixed to the support so as to be movable therewith, a fan blade retained by the housing; and an electric motor operatively coupled to said fan blade and energizable to produce rotation thereof. The coupling surfaces are shaped and arranged to produce in response to rotation of the support relative to the base, movement of the housing having both horizontal and vertical components.
