outdoor fan

Abstract

The invention discloses an outdoor electric fan. The outdoor electric fan comprises a motor stator and a rotor. The rotor is provided with a through hole. A rotating shaft penetrates the through hole. One end of the rotating shaft is connected with a front end face through a first bearing. The front end face is rotationally connected with a front framework in the circumferential direction. The outer side of the stator is rotationally connected with a rear framework. The other end of the front framework is rotationally connected with the other end of the rear framework. The rotating shaft is rotationally provided with fan blades. The rotating shaft is provided with a protruding ring used for positioning the fan blades, and the other end of the rotating shaft is connected with a supporting rod through a second bearing. The supporting rod and the periphery of the rotating shaft are the same in structure. The outer ring of the second bearing is rotationally connected with the supporting rod. A clamping part is arranged on the side face of the stator. When the supporting rod is clamped in the clamping part, the electric fan is in an unfolded state, the rotor is provided with an embedding block, and the rotating shaft is provided with a first embedding groove. The supporting rod is provided with a second embedding groove. A drill bit is arranged at the end portion of the supporting rod. The outdoor electric fan can be folded, the air volume is large, carrying is convenient, and meanwhile the outdoor electric fan can be conveniently placed and positioned in various outdoor environments.

Description

technical field [0001] The invention belongs to the technical field of electric fans, in particular to an outdoor electric fan. Background technique [0002] Existing electric fans are essential electrical appliances in summer, especially for outdoor sports enthusiasts. Flying insects and heat in the wild are unbearable when camping in summer, and existing electric fans are either particularly large in size or have a particularly small air volume. Either it is difficult to carry or the wind volume is very small. At the same time, the outdoor environment is complicated, and it is difficult for ordinary electric fans to adapt to different environments. Therefore it is imperative to develop a kind of electric fan that is convenient to carry and has a large air volume. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an outdoor electric fan, which can be folded, has a large air volume, is convenient to carry, and ...
