The model utility content
The purpose of the utility model provides the self-charging energy-saving fan that a kind of simple in structure, reliable performance, cost are low, can when having a power failure, use.
For solving the problems of the technologies described above, the utility model provides a kind of self-charging energy-saving fan, comprising: fan electromotor, and fan electromotor comprises pto; Blast fan, blast fan are arranged on the pto of fan electromotor; Wind-driven generator; The generating impeller, the rotation of generating impeller-driven wind-driven generator; The generating impeller is arranged on the air side of blast fan; Storage battery, wind-driven generator is electrically connected with storage battery.
Further, the self-charging energy-saving fan also comprises speed change gear, and the generating impeller drives wind-driven generator work through speed change gear.
Further, the generating impeller is the pendulum fan blade of self-charging energy-saving fan.
Further, the number of generating impeller is two, and two generating impellers are separately positioned on the both sides of the pto of fan electromotor.
Further, the number of generating impeller is a plurality of, and a plurality of generating impellers center on the circumferential setting of the pto of fan electromotor equably.
Further, the self-charging energy-saving fan also comprises fan guard, and the generating impeller is arranged on the fan guard.
Further, the generating impeller is a suction impeller.
Further, the self-charging energy-saving fan also comprises one or more USB interfaces.

Description of drawings
Fig. 1 is first embodiment's of the utility model a structural representation.
Fig. 2 is another embodiment's of the utility model a structural representation.
Embodiment
Shown in Fig. 1-2, a kind of self-charging energy-saving fan of the self-charging energy-saving fan in the utility model is characterized in that, comprising: fan electromotor, and fan electromotor comprises pto; Blast fan 2, blast fan 2 are arranged on the pto of fan electromotor; Wind-driven generator; Generating impeller 3, generating impeller 3 drives the wind-driven generator rotation; Generating impeller 3 is arranged on the air side of blast fan 2; The storage battery (not shown), wind-driven generator is electrically connected with storage battery.Therefore; When civil power, the self-charging energy-saving fan in the utility model can normally resemble direct use the conventional fan, when in use; The operation that blast fan is dried; Simultaneously, the wind that blast fan blows out drives the generating impeller and drives the wind-driven generator rotation, thereby realizes the function to charge in batteries.When having a power failure and since in storage battery preliminary election filled electricity, therefore, can directly use the storage battery that has charged is the power supply of the self-charging energy-saving fan in the utility model, thereby also can normally use fan when guaranteeing to have a power failure.It is thus clear that; Self-charging energy-saving fan in the utility model does not need directly to utilize civil power itself to charge in batteries; Drive wind turbine power generation but utilize wind that blast fan blows out to drive the generating impeller, have that simple in structure, reliable performance, cost are low, the advantage of energy-conserving and environment-protective.
Preferably, the self-charging energy-saving fan also comprises the speed change gear (not shown), and generating impeller 3 drives wind-driven generator work through speed change gear.Therefore, can be through will the generate electricity faster rotational speed of impeller 3 of this speed change gear, to drive the wind-driven generator rotary electrification quickly.
Preferably, the self-charging energy-saving fan also comprises one or more USB interfaces 6, and USB interface 6 is electrically connected with storage battery, so that be the external equipment power supply.
As a preferred embodiment, as shown in Figure 1, generating impeller 3 is pendulum fan blades of self-charging energy-saving fan.Therefore, can utilize the pendulum wind process of pendulum fan blade to drive wind turbine power generation.
As another preferred embodiment, as shown in Figure 2, the self-charging energy-saving fan also comprises fan guard 1, and generating impeller 3 is arranged on the fan guard 1.Preferably, the number of generating impeller 3 is two, and two generating impellers 3 are separately positioned on the both sides of the pto of fan electromotor.Preferably, the number of generating impeller 3 is a plurality of, and a plurality of generating impellers 3 center on the circumferential setting of the pto of fan electromotor equably.In this embodiment, the generating impeller has only stopped seldom a part of air-out area, therefore, can the normal use of fan not impacted.Further, the generating impeller is a suction impeller, and is in this case, littler to the influence of the wind that blast fan blew out.
The utility model utilizes wind that its blast fan blows out to drive the generating impeller and drives wind turbine power generation, has that simple in structure, reliable performance, cost are low, the advantage of energy-conserving and environment-protective.
