Preferably, the air inlet is outwards protruded away from the lower cover of the blade to be in a horn shape.
Preferably, the wind blades all extend to the edges of the upper blade cover and the lower blade cover along an arc shape from the position close to the circular hole.
Preferably, when the wind wheel is actually installed, the circular holes formed in the middle of the upper cover and the lower cover of the blade can be connected with the rotor of the fan in a blank pressing fastening mode.
Preferably, circular holes are formed in the middle parts of the blade upper cover and the blade lower cover, are matched with the 92 series fan and the 102 series fan and can be used by fans with the diameters of 250mm, 280mm, 310mm and 350mm respectively.
Compared with the prior art, the utility model relates to a beneficial effect for high-efficient wind wheel of fan: the guide vanes are arranged on the inner sides of the lower blade covers, so that air inlet is smoother, turbulence can not be generated, and the air inlet volume of the fan is increased, so that the performance of the fan is improved under the condition that the power of a motor is not increased, and the fan is more efficient.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 to 2, the high-efficiency wind wheel for a fan of the present embodiment includes a blade upper cover 1 and a blade lower cover 2 which are arranged in parallel up and down. Specifically, blade upper cover 1 and blade lower cover 2 set up relatively, and blade upper cover 1 and blade lower cover 2 both are the cyclic annular lid that the middle part set up the circular port.
Wherein, all be provided with the circular port in the middle part of blade upper cover 1 and blade lower cover 2, circular port and 92 series fans and 102 series fan adaptations can supply the diameter to be 250mm, 280mm, 310mm and 350 mm's fan respectively and use. When the wind wheel is actually installed, the circular holes formed in the middle of the upper cover 1 and the lower cover 2 of the blade are connected with the rotor of the fan in a blank pressing fastening mode, and other third parts do not need to be used for transition connection.
Specifically, evenly set up a plurality of syntropy crooked arc wind blade 3 between blade upper cover 1 and the blade lower cover 2, wind blade 3's trend all uses near the circular port as the starting point and outwards extends to the border department of blade upper cover 1 and blade lower cover 2 along the arc. One side of the blade upper cover 1, which is far away from the blade lower cover 2, is provided with an air inlet 4 protruding outwards, specifically, the air inlet 4 is far away from the blade lower cover 2 and protrudes outwards to form a horn shape, so that the air inlet 4 is used in cooperation with external equipment and can be in butt joint cooperation with the air inlet 4, and the air exhaust and heat dissipation of the fan are realized.
Be provided with the water conservancy diversion piece 5 of leanin near the circular hole department of blade upper cover 1, a plurality of water conservancy diversion pieces 5 form the slope ring portion around the circular hole, and when the air current got into blade lower cover 2, water conservancy diversion piece 5 can reduce the resistance of blade lower cover 2, made the air inlet more smooth, can not produce the turbulent flow. Meanwhile, the air flow passing through the air blades 3 can be pushed, so that the air inlet volume of the fan is increased, the air outlet volume of the fan is increased under the condition that the power of the fan is not increased, and the fan is more energy-saving and efficient.
The utility model provides a high-efficient wind wheel for fan through set up the water conservancy diversion piece in blade lower cover inboard, increases the intake of fan, compares with prior art, and this high-efficient wind wheel has increased the air output of fan under the condition that does not increase motor power, makes the fan more high-efficient.
Finally, it should be noted that: the above embodiments are merely illustrative of the technical solutions of the present invention, and not limitative thereof; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
