The reasons why there is no wind in the electric fan are:
1. The fan blades are not properly attached. If they are loose, tighten them in time.
2. The fan blade is installed in the wrong direction and must be removed and reinstalled.
3. The fan blades are not original and have poor wind stirring capacity. If the fan blades are too small, there will be no wind. Simply replace them with the original fan blades.
4. Fan blades are damaged, leading to air leaks and weakened wind power. Just replace the fan blades with new ones in time.
5. The fan blade surface is too dirty, resulting in weak wind. Just clean it in time.
A fan refers to a device used to generate wind and cool during days chot. An electric fan is a device powered by electricity to generate airflow. The fan inside is powered and rotates by natural wind to achieve a cooling effect. Mechanical fans were born on the roof. In 1829, an American named James Byron took inspiration from the structure of a clock and invented a mechanical fan that could be attached to the ceiling and driven by a spring. The cool breeze brought by the rotating blades of this fan makes people happy, but it is difficult to climb a ladder to go back up.
In 1872, a Frenchman named Joseph developed a mechanical fan started by a mechanical turbine and driven by a gear chain device. This fan was much more sophisticated than the mechanical fan invented by Byron. also more practical. In 1880, the American Schuller installed the blades directly on the engine for the first time, thenconnected it to the power supply. The blades were spinning quickly and a cool breeze was blowing. It was the world's first electric fan.
