Really smart "Mini Air Cooling Fan" in "stepless" principle is a traditional fan disruptive innovation, it can be accurate to 1% of the maximum amount of wind fans accuracy during use. Intelligent natural wind intelligent fan produced is continuously changing in subtle "stepless" basis up to achieve "Mini Air Cooling Fan" natural wind, while under the control of the smart chip to achieve a random wind change, with a certain degree of Probability joined windy and windless conditions. Such natural wind is a wind change and the nature of the wind, it is never repeated. And "Mini Air Cooling Fan" may provide for different groups of really smart wind, we might be explained in detail by illustrative examples, stepless principle heatstroke in real life:
