Problems solved by technology

The motor on the axial flow fan is arranged on the air inlet duct of the axial flow fan, and the diameter of the cross section of the motor is equivalent to the diameter of the cross section of the hub of the wind wheel, so that the wind on the air duct basically passes around the motor, which is not good for the motor. The heat dissipation effect directly affects the duration and service life of an axial flow fan

Abstract

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.

Description

technical field [0001] The invention relates to a portable fan specially used for gardening. Background technique [0002] In the prior art, an axial flow fan is often used to blow the fallen leaves. However, for the convenience of operation, people often need to carry the blower to collect and blow the fallen leaves, which is very inconvenient to use. In addition, existing axial flow fans generally include a wind wheel and a motor. The middle part of the wind wheel is press-fitted on the outer rotor of the motor with an interference fit. The rotation of the outer rotor of the motor drives the wind wheel to rotate. Axial movement, so that the wind is released in the axial direction. In order to prevent the wind wheel from hurting people when it rotates, a net cover is generally provided to cover the wind wheel to prevent people from touching the wind blades on the wind wheel. The motor on the axial flow fan is arranged on the air inlet duct of the axial flow fan, and the di...
