Q: What are your misunderstanding blowing ？: Many people like to blow fans for a long time. They feel like they've just cooled off, and they're going to feel like they're still hot. It's not as good as blowing comfortably for a long time. However, a long time to the fan blowing, the body temperature will decrease with the evaporation of large amounts of sweat, easily lead to colds, colds, abdominal pain, diarrhea and other diseases.

Q: Why do most fans only have 3 blades?: We usually use the fan for axial fan, the blade is odd, this is because if the even shape symmetrical blades, and no adjustment of balance, it is easy to make the system resonance occurs, if the blade material is unable to resist fatigue due to vibration, will cause the blade or the spindle is broken, so odd pieces of the fan blade design on asymmetric multi axis design

Q: When did the electric fan start to appear?: In 1882, a commercial electric fan appeared in the United States for the first time. Household appliances that only two fan blades, is New York's Kaka zurs engine factory Kroll chief technician Hughes Katz Hoy pull invention
