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
The invention belongs to the electron controls technology field, relate to a kind of intermittent running ventilation fan controller.
Background technique
Various model ventilation fan common features are on the market: ventilation fan can only its running of manual control, and it can not be opened automatically, can not close automatically.When some special confined space need regularly be taken a breath, can only artificially control ventilation fan work, ventilation fan must keep in mind the power supply of cutting out it after connecting the power supply running constantly.In case you forget the power supply of closing ventilation fan, gently then cause power wastage, heavy then cause ventilation fan because of the overheated ventilation fan motor that burns out that works long hours, but also buried hidden danger for fire.
After intermittent running ventilation fan controller of the present invention is connected power supply; ventilation fan can periodically be worked; and the time of intermittent running can regulate respectively as required; so both effectively stopped unnecessary power wastage; also effectively protected the ventilation fan motor can effectively not ensure normal use and the Electrical Safety of ventilation fan because of overheated being burnt out of long-time running.
