Description

Air circulation fan

Technical Field

The utility model belongs to the field of fans, and particularly relates to an air circulation fan.

Background

The existing fan utilizes electromagnetic induction to enable the blades to rotate rapidly, and the rapidly flowing air enables moisture on the surface of a human body to evaporate after passing through the human body and absorbs heat, so that the human body feels cool. However, throughout the operation of the fan, the fan does not have a cooling effect on the indoor air, and if the indoor air is at a high temperature, the blown air is also at a high temperature. Conversely, heat is released during operation of the fan, resulting in an increase in temperature near the fan. The air circulation fan mainly aims at forming convection circulation for indoor air and achieving the effect of balancing temperature by reasonable air flow direction. The air circulation fan cannot be directly used as a refrigerator, is often used for being matched with an air conditioner, and achieves the effects of rapid refrigeration and room temperature balancing.
