The output end connection of motivation, the motor outside is provided with motor cover.
Preferably, the preceding fan housing center is provided with wind-collecting cover, annular string air channel is provided with the outermost of preceding fan housing, in institute
State and be uniformly provided with preceding wind channel between wind-collecting cover and annular string air channel.
Preferably, it is arranged with rear wind channel above and below the rear air cover, and on rear wind channel end and preceding fan housing
Annular string air channel be connected, be provided with drainage connector, described drainage connector one end and rear air inducing in rear wind channel end
Road, other end is connected with motor cover.
Preferably, the wind-collecting cover is provided with annular grasswort backflash.
The utility model is to increase heat sinking function to electric fan, improves radiating efficiency, so that service life is improved, to electric wind
The structure of fan has done brand-new design, and the beneficial effect using above technical scheme is：The collection being provided with by preceding fan housing center
Fan housing, the wind part that electric fan is blown out is guided to annular and is gone here and there in air channel by preceding wind channel, then by after on rear air cover
Wind channel guides at drainage connector wind, and the wind for being blown out electric fan by drainage connector is sent into motor cover, to motor
Motor in cover is cooled down, wherein the annular grasswort backflash on the wind-collecting cover, improves the collection electric wind of wind-collecting cover
Fan the ability of the wind of blowout.

Specific embodiment
Below against accompanying drawing, by the description to embodiment, specific embodiment of the present utility model is made further in detail
Thin explanation, it is therefore an objective to help those skilled in the art have to design of the present utility model, technical scheme it is more complete, accurate and
Deep understanding, and contribute to it to implement.
As shown in Figure 1 to Figure 3, the utility model is a kind of electric fan, is to increase heat sinking function to electric fan, improves radiating
Efficiency, so as to improve service life.
Specifically, as shown in Figure 1 to Figure 3, including preceding fan housing 1, rear air cover 2, flabellum 3 and motor 4, as shown in figure 1,
The preceding fan housing 1 is connected with rear air cover 2, and flabellum 3 is located between preceding fan housing 1 and rear air cover 2, the output end of flabellum 3 and motor 4
Connection, the outside of the motor 4 is provided with motor cover 40.
As shown in Fig. 2 the preceding fan housing center is provided with wind-collecting cover, annular string air channel is provided with the outermost of preceding fan housing,
Wind channel before being uniformly provided between the wind-collecting cover and annular string air channel；As shown in figure 1, right above and below the rear air cover
Title is provided with rear wind channel, and rear wind channel end is connected with the annular string air channel on preceding fan housing, is set in rear wind channel end
There are drainage connector, described drainage connector one end and rear wind channel, other end is connected with motor cover；As shown in figure 3,
The wind-collecting cover is provided with annular grasswort backflash.
Specific works mode is illustrated with specific embodiment below：
After we are powered to motor 4 motor 4 is rotated with flabellum 3, the wind produced by flabellum 3 can be from electric fan
Preceding fan housing 1 in blow out, have a wind on the wind-collecting cover 10 on preceding fan housing 1, then first some wind can with
The preceding wind channel 11 that wind-collecting cover 10 is connected is reached in annular string air channel 12, while the annular grasswort backflow on wind-collecting cover 10
In the presence of groove 10-1, the wind for entering preceding wind channel 11 is had little time in annular grasswort backflash 10-1 because air velocity is too fast
Backflow effect it is lower can again go into preceding wind channel 11, then reach annular and go here and there in air channel 12, then as the source of backwind
Source is constantly come in, and makes the wind channel 20 after on rear air cover 2 of the wind in annular string air channel 12, then by drainage connector 21
Into in motor cover 40, then cooled down to motor 4, and the rotating speed with electric fan quickening, the wind of blowout can be more
Come bigger, the flow and flow velocity hence into the wind in motor cover 40 can also become big, be achieved in that the rotating speed of motor 4 becomes
Hurry up, the electric current that flows through of inside becomes big, and caloric value is bigger, at the same into the wind in motor cover 40 flow and flow velocity also increasingly
Greatly so that cooling-down effect is also more obvious, radiating efficiency is improved, so as to improve service life.
The utility model is exemplarily described above in association with accompanying drawing, it is clear that the utility model is implemented not
Limited by aforesaid way, as long as employ the various unsubstantialities that method design of the present utility model and technical scheme are carried out
Improvement；Or it is not improved, above-mentioned design of the present utility model and technical scheme are directly applied into other occasions, at this
Within the protection domain of utility model.
