View Patent ↗A hurricane and power outage fan that includes a battery powered fan that is operable for a period of time on the power stored in a number of batteries provided with the fan. The battery-powered fan includes an AC to DC converter that supplies power to a trickle charge circuit for keeping the batters fully charged as long as the AC plug is plugged into a power outlet. When the power goes out, the fan runs on the batteries for a predetermined period of time.
1. A fan comprising:
a DC fan assembly;
a DC battery supply;
a power supply including a means for receiving and providing AC power, an AC-DC converter, a charging circuit and a means for supplying said DC power to said DC fan assembly when AC power is not received;
said AC-DC power converter in electrical communication with said AC power means and said DC fan assembly for converting AC power to DC power for providing said DC power to said DC fan assembly;
said charging circuit in electrical communication with said AC power means and said DC battery supply for charging said DC battery supply with said AC power when AC power is available;
a housing for supporting and enclosing said DC fan assembly and said power supply; and
said housing further comprising a tray for storing said DC battery supply.
2. A fan as recited in claim 1 , wherein said DC fan assembly comprises:
a DC motor having an output shaft; and
