Abstract
Description
technical field
[0001] The invention relates to the technical field of automatic ventilation, in particular to a fan with automatic ventilation function. Background technique
[0002] The mechanical fan originated in 1830. An American named James Byron was inspired by the structure of the clock and invented a mechanical fan that could be fixed on the ceiling and driven by a clockwork. The gentle breeze from the garden makes people feel happy, but it is troublesome to climb up the ladder to wind it up. In 1872, a Frenchman named Joseph developed a mechanical fan that was started by a clockwork turbine and driven by a gear and chain device. This fan was much more refined than the mechanical fan invented by Byron, and it was easier to use. In 11880, the United States For the first time, Ren Shule installed the blades directly on the motor, and then connected to the power supply. The blades rotated rapidly, and the cool wind rushed to the face. This is the world's first electri...
