"Cube" is a multi-functional node modular lithium battery site fan design with a cubic structure. The main body of the fan is supported by a column-type cube frame in appearance. Each node on the frame can be arbitrarily added, and devices such as flashlight, atomization and suspension can be added to adapt to various functional requirements and environments. The color is matched with black and bright orange. The outer frame material is black paint copper-aluminum alloy, the fan blades are translucent PC plastic, and each additional node is made of high-strength plastic to make it more durable. The overall structure is simple, easy to process and manufacture, and has high economic benefits. The industrial wind composed of the cold texture of metal and the color tone of plastic materials makes it more popular in the market.
