Background technique
Generally, axial fan is to be subjected to the rotating force of external drive source such as motor etc. and to rotate, and the machine that air is axially blown.It is not only applicable to household appliances such as electric fan, air conditioner and refrigerator, is widely used in multiple fields such as space shuttle and motor yet.
As shown in Figures 1 and 2, the center of existing axial fan is provided with the wheel hub 1 that combines with the live axle of motor, also is the rotating center of axial fan.Center on the outer circumferential face setting of wheel hub and be connected with several fan blade 2 with air-supply effect.These several fan blade 2 guide air and produce air-flow when axial fan rotates.Around the outer circumferential face at fan blade 2 tops and the water ring 3 that is connected with each fan blade 2 top joint, water ring 3 drives the water ring rotation and condensed water got to landing low temperature on the condenser when axial fan rotates effect.
During axial fan work, rotate simultaneously in the live axle drive lower hub 1 and the fan blade 2 of motor, fan blade guides air and produces air-flow when axial fan rotates.Because the wheel hub 1 of above-mentioned existing axial fan is discoid, wheel hub 1 is sealing shape, does not have air-guiding aisle, and wheel hub 1 can not ventilate when rotated.Therefore, this can produce eddy current at the central part of axial fan, has influenced the exhaust air rate of axial fan.Simultaneously, at the very big wind-force resistance of central part existence of axial fan, reduced the exhaust air rate of axial fan.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that existing product exists, and provide a kind of improved axial fan, it can eliminate the eddy current of axial fan central part, and can increase the axial fan exhaust air rate under identical rotating speed, has improved the air-supply efficient of axial fan.
The objective of the invention is to realize by following technological scheme.
A kind of axial fan, comprise the axial fan body, the axial fan body is provided with the wheel hub that combines with the live axle of motor, on the outer circumferential face of wheel hub, be provided with and be connected with several fan blade, around the outer circumferential face at fan blade top and the water ring that is connected with each fan blade joint, keep at a certain distance away on the outer circumferential face of the central axle sleeve of wheel hub on the described wheel hub and radioactively be provided with several small fan blades, the bottom and the central axle sleeve of these several small fan blades link together; Outer circumferential face round the small fan vane tip is provided with the connecting ring that links together with small fan vane tip and several fan blade bottoms of wheel hub outer circumferential face.
Each small fan leaf of described several small fan blades is corresponding one by one distribution with each fan blade of several fan blade on the outer circumferential face of wheel hub, and convergent is along extending wheel hub central axle sleeve place.
Described small fan blade and connecting ring are one-body molded on the axial fan body.
Beneficial effect of the present invention, the present invention makes to have several air-guiding aisles on the wheel hub because the wheel hub of axial fan is provided with several small fan blades, the fan blade of wheel hub guides air and produces air-flow when axial fan rotates.Can eliminate the eddy current of axial fan central part, and can under identical rotating speed, increase the axial fan exhaust air rate, improve the air-supply efficient of axial fan.
Describe the present invention below in conjunction with the drawings and the specific embodiments.
