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, when the fan is used in an outdoor environment, the air volume of the fan fluctuates due to the existence of natural wind, which affects the blowing experience, especially when the natural wind and the fan are reversed, the air volume will decrease.

The invention discloses a multifunctional electric fan which comprises a motor. The motor comprises a stator and a rotor. A polygonal rotating shaft is arranged on the rotor in a penetrating mode. One end of the polygonal rotating shaft is connected with a front end face through a first bearing, and the front end face is circumferentially connected with one ends of a plurality of front skeletons in a rotating mode. The outer side of the stator is connected with one ends of a plurality of rear skeletons in a rotating mode. Fan blades are arranged on the polygonal rotating shaft in a rotating mode and located between the front end face and the motor. The polygonal rotating shaft is provided with a protruding ring used for positioning the fan blades. The other end of the polygonal rotating shaft is connected with a supporting rod through a second bearing. The outer circle of the second bearing is connected with the supporting rod in a rotating mode. A clamping part is arranged on the side face of the stator. When the supporting rod is clamped into the clamping part, the electric fan is in an unfolded state. The supporting rod is provided with a sector-shaped air regulation plate in a rotating mode. The air regulation plate is provided with a plurality of gear contacts which are evenly distributed along an arc line. The center of the circle of the sector-shaped air regulation plate is connected with a conducting plate in a rotating mode. The constant wind electric fan can be folded, and the effect that the blast capacity can be kept constant in the outdoor fanning process is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of electric fans, in particular to a multifunctional 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, when the fan is used in an outdoor environment, the air volume of the fan fluctuates due to the existence of natural wind, which affects the blowing experience, especially when the natural wind and the fan are reversed, the air volume will decrease. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a multifunctional electric fan, which can be folded, has a large air volume and is...
