目前风扇的发展趋势是节能、 功能多样化， 在外观和功能上追求个性化，

The current development trend of fans is to save energy, diversify functions, and pursue personalization in appearance and functions. Computer-controlled, <br>natural wind, sleep wind, and negative ion functions, which are originally air-conditioning functions, are also used by many fans. There are <br>more practical functions such as adding lighting and mosquito repellent. The research and use of temperature-controlled fans started very early, the most <br>common in industrial control , and the temperature-controlled small fans are also used in notebooks. At present, the most researched temperature control fan is based on single-chip microcomputer or <br>FPGA/CPLD as the control core. Because of its fast running speed, stable performance, high digitization, high precision, <br>strong adaptability and other characteristics, it has important significance for automatic control of electrical appliances. And value, in addition to this, some other technical <br>functions are added to make the fan more user-friendly, which is of great benefit to the development of the fan industry.
