Turbine fan with blades having damping structures

The invention relates to the technical field of breathing machine accessories, in particular to a turbine fan with blades having damping structures. The turbine fan comprises a small motor and a lateral rotating cylinder mounted on a rotating shaft of the small motor. The turbine fan with blades having damping structures adopts a split type structural design, adjustable centrifugal fan blades areinserted into an inner side assembling barrel through outer telescopic shafts to be connected to the lateral rotating cylinder, and centrifugal force generated when the small motor drives the lateralrotating cylinder to rotate at a high speed translates outwards; the angles of the adjustable centrifugal fan blades are adjusted by matching with an arc-shaped guide seat on the inner side surface ofan outer annular frame, so that a wind direction component and a blowing mode are changed, and thus, the application range is greatly expanded; a reset spring used for controlling the adjustable centrifugal fan blades to elast
