An outdoor electric fan

Abstract

The invention discloses an outdoor electric fan. The outdoor electric fan comprises a stator and a rotor of a motor. The rotor is provided with a polygonal through hole. A polygonal rotary shaft is arranged in the polygonal through hole. A front end face is connected to one end of the polygonal rotary shaft through a first bearing. The front end face is rotatably connected with one ends of a plurality of front skeletons in the circumferential direction. The outer side of the stator is rotatably connected with one ends of a plurality of rear skeletons. The other ends of the front skeletons are correspondingly and rotatably connected with the other ends of the rear skeletons in a one-to-one correspondence mode. Fan blades are rotatably arranged on the part, between the front end face and the motor, of the polygonal rotary shaft. A convex ring used for positioning the fan blades is arranged on the polygonal rotary shaft. A supporting rod is connected to the other end of the polygonal rotary shaft through a second bearing. The supporting rod and the periphery of the polygonal rotary shaft are of the same structure. An outer ring of the second bearing is rotatably connected with the supporting rod. The side face of the stator is provided with a clamping part. A drill bit is arranged at the end of the supporting rod. The outdoor electric fan can be folded, is large in wind quantity and convenient to carry, and can be placed and positioned conveniently 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] The existing electric fan is an indispensable electrical appliance in summer, especially for outdoor sports enthusiasts. During summer camping, the flying insects and the heat in the wild are unbearable, and the existing electric fan is either very large in size or very small in air volume. Either it is difficult to carry or the air volume is very small. At the same time, the outdoor environment is complex, and the general electric fan is difficult to adapt to the placement of different environments. Therefore, it is imperative to develop an electric fan that is portable and has a large air volume. SUMMARY 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 is convenient...

Problems solved by technology

[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 complex, and ordinary electric fans are difficult to adapt to different environments.
