Abstract
The utility model relates to an emergency electric fan, comprising a base, a back cover, blades, a front cover, a direct current motor, a shell of a machine head, a switch of the power supply of a motor, a rectifier, an input plug of the power supply of the rectifier and an accumulator, wherein, the accumulator is arranged on the base of an electric fan. Compared with an exiting alternating current electric fan and a direct current electric fan, the emergency electric fan has the advantage of portability; alternating current, as well as direct current can be used as the power supply of the emergency electric fan; the emergency electric fan is characterized in that the emergency electric fan can be used in the places provided with or without power supply and can be used in power cut. The emergency electric fan is particularly suitable for companies, households, students and outbound personnel.
Description
The utility model belongs to a kind of electric fan.
Existing electric fan generally with Ac as power supply, when having a power failure or at this class electric fan of place that does not have electricity, just can't use.In some occasions, as employed electric fan on the automobile, on the train be with direct current as power supply, this class electric fan can not be with Ac as power supply, this is restricted on using scope, is not suitable as domestic electric fan.
Task of the present utility model is: at existing Ac fan and the existing deficiency of DC electric fan, provide a kind of both available Ac as power supply, available again direct current is as power supply; Both can use, can and not have the electric also spendable a kind of emergency electric fan in place when having a power failure again in the place that power supply is arranged.
Task of the present utility model is finished as follows: emergency electric fan is made up of base (3), back cover (5), fan blade (6), front shroud (7), direct current generator (8), head shell (9), electric power switch (11), rectifier (12), rectifier power input plug (13).Wherein on the head shell (9) of electric fan or base (3), be provided with 1 motor DC supply hub (10).On the base (3) of electric fan, storage battery (16) is housed, on storage battery (16), is provided with charge in batteries jack (17) and battery feed output plug (18), on rectifier (12), be provided with rectifier power supply output plug (15).The occasion of ac power supply is being arranged, rectifier power supply output plug (15) is inserted in the motor DC supply hub (10), rectifier power input plug (13) is inserted in the socket of ac power supply, open electric power switch (11) after, electric fan will rotate.In the occasion of AC-less power, battery feed output plug (18) is inserted in the motor DC supply hub (10), open electric power switch (11) after, electric fan will rotate.When need accumulators (16) charges, rectifier power supply output plug (15) is inserted in the charge in batteries jack (17), rectifier power input plug (13) is inserted interior the getting final product of socket of ac power supply.
The utility model is compared with DC electric fan with existing Ac fan, has easy to carry; Both available Ac is as power supply, and available again direct current is as power supply; Both can use, can and not have the electric also spendable characteristics in place when having a power failure again in the place that power supply is arranged.This emergency electric fan unit of being particularly suitable for, family, student, migrant person use.
