The invention discloses a portable gardening special fan which comprises a vehicle, a shell obliquely arranged on the vehicle, a second chamber, a transition section, a first chamber, a plurality of air inlets, a motor, a wind wheel and a wind guide ring. The second chamber, the transition section and the first chamber are formed from one end of the shell to the other end of the shell. The air inlets are evenly distributed on the end face of the other end of the shell in an annular shape. The motor and the wind wheel are coaxially arranged in the second chamber. The wind guide ring is an annular plate and is in an arc shape in the radial direction, and an arc opening faces the first chamber. The large ring end of the wind guide ring is fixedly arranged on the side wall close to the other end of the shell, the small ring end of the wind guide ring is arranged by extending towards the tail end of the motor, and the radial length of the wind guide ring is smaller than one sixth of the cross section diameter of the second chamber. By adoption of the portable gardening special fan, fallen leaves can be rapidly collected, labor intensity is relieved, and during use of the portable gardening special fan, a motor of an axial flow fan is synchronously cooled in real time, and the service life of the axial flow fan is prolonged.
