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 an outdoor constant-wind fan comprising a motor. A supporting rod is axially arranged on a stator of the motor in a penetrating manner. One end of the supporting rod is provided with a front end face. The front end face is rotationally connected with one end of each of a plurality of front frameworks. The periphery of the stator is rotationally connected with one end of each of a plurality of back frameworks. The supporting rod is provided with a first bearing. The inner ring of the first bearing is fixedly connected with the supporting rod. Blades are rotationally connected with the outer ring of the first bearing. A rotor is provided with a plurality of first embedding blocks. The first bearing is provided with first embedding grooves. The supporting rod is provided with a first polygonal clamping ring. The stator is provided with a first polygonal groove. The supporting rod is provided with a clamping sleeve. A fan-shaped wind force adjusting plate is rotationally arranged on the clamping sleeve. The fan-shaped wind force adjusting plate is provided with grade contacts. An electricity conducting plate is rotationally connected with the center of the circle of the fan-shaped wind force adjusting plate. The electricity conducting plate cooperates with the grade contacts to conduct electricity and is connected with a circuit of the motor in parallel. The outdoor constant-wind fan can be folded and guarantee that the wind force is kept constant when blowing air outdoors.
Description
technical field [0001] The invention belongs to the technical field of electric fans, in particular to an outdoor constant wind 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 in the prior art, the present invention provides an outdoor constant wind fan, which can be folded, has a large air volume and is eas...
