Abstract
The invention provides a control circuit of a fan simulating natural wind. The control circuit is constructed through two NE555 time-base circuit chips IC1 and IC2. Two pulse square-wave oscillators different in period and pulse width are constructed through the two chips IC1 and IC2 and corresponding resistor-capacitor units correspondingly. The output ends of the two oscillators are loaded to a control electrode of a both-way thyristor VS through a diode D3 and a diode D4. Due to the fact that the two oscillators are different in period and pulse width, the conduction time of the both-way thyristor VS is uncertain, and the wind sent out by the fan controlled by the both-way thyristor VS is changed at random. Thus, the control circuit of the fan simulating the natural wind can control the fan to well simulate the natural wind, and the wind blowing effect of the fan is obviously superior to the wind blowing effect of fans on the market.
