Abstract

The invention discloses a discontinuous running ventilator controller. The discontinuous running ventilator controller is characterized by comprising a 220V alternating-current power supply, a resistive and capacitive pressure relief and full-bridge rectifying circuit, a 12V voltage stabilizing circuit, a bi-stable timing circuit, a relay driving circuit and a ventilator control circuit, the model of a time-base circuit IC1 in the bi-stable timing circuit is NE555. A normal ventilator cannot be turned on or turned off automatically. When some enclosed spaces need timed ventilation, the ventilator can only be controlled to work manually, and after the ventilator runs, a person must always thick about powering off the ventilator, once the person forgets to power off the ventilator, electricity is wasted, more severely, the ventilator can be burnt out due to overheating of long-time working, and hidden danger is left for fire disasters. Electricity waste is eradicated completely and effectively, and normal use and safety of the ventilator are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electronic control, and relates to an intermittent operation switching air fan controller. Background technique [0002] The common feature of various types of ventilating fans on the market is that the ventilating fan can only be controlled manually, and it can neither be turned on nor off automatically. When some special confined spaces need to be ventilated regularly, the ventilation fan can only be controlled manually. After the ventilation fan is connected to the power supply, it must always be thought of to turn off its power supply. Once you forget to turn off the power supply of the ventilating fan, it will cause a waste of electricity in the light, or cause the ventilating fan to burn out due to overheating of the ventilator for a long time, and also lay a hidden danger for the occurrence of fire. [0003] After the intermittent operation switching air fan controller of the present invention is ...
