AI Technical Summary
Although the air collector of the existing fan blades can collect air, it also blocks the outside air, causing the incoming air volume to decrease and thus reduce the outgoing air volume.
It adopts a superchargeable fan blade structure and extends a plurality of slope blocks on the inner periphery of the air collecting ring and the windward surface of the fan blades, so that the pressure increases when the air flow passes through, and the air output volume increases.
It achieves the air collection effect of the fan structure, while increasing the air output, enhancing the air flow gathering ability, and improving the heat dissipation effect.

Abstract
Description
Technical Field
[0001] The invention relates to a fan structure, and in particular to a pressurized fan blade structure. Background Art
[0002] In order to achieve the wind collecting effect, fan blades are usually provided with wind collecting plates on the outer edge of each blade, so that the wind caused by each blade can be shielded by the wind collecting plates and the wind leakage along the wheel diameter direction is reduced, so as to achieve the wind collecting effect.
[0003] However, although the above-mentioned fan blades can have a wind-collecting effect due to the wind-collecting sheets, the wind-collecting sheets will also block the outside air and prevent the outside air from entering the fan blades along the wheel diameter direction, thereby causing the air intake of the fan blades to decrease, and the air output of the fan blades to decrease accordingly, which needs to be overcome.
[0004] In view of this, the creators of the present invention have devoted themselves to the research and application of the above-mentioned prior art, and have tried their best to solve the above-mentioned problems, which has become the goal of the creators' improvement. Utility Model Content
[0005] The invention provides a pressurized fan blade structure, which utilizes the inner periphery of the wind collecting ring and the windward surface of each fan blade to extend a plurality of slope blocks with a thickness gradually decreasing from the lower periphery to the upper periphery, so as to achieve the advantages of the fan blade structure in collecting wind and increasing the air output.
[0006] In the present invention, a pressurized fan blade structure is provided, comprising: a hub; a plurality of fan blades, one end of which is connected to the hub and the other end of which respectively has an outer edge, and each of the fan blades has a relative windward surface and a leeward surface; and a wind collecting ring, which is surrounded and connected to the outer edge of each of the fan blades, and the wind collecting ring has a relative upper edge and a lower edge, and the inner edge of the wind collecting ring and the windward surface of each of the fan blades extend with a plurality of slope blocks whose thickness gradually decreases from the lower edge toward the upper edge; wherein, the wind caused by the rotation of each of the fan blades driven by the hub will be guided by each of the slope blocks and flow into the wind collecting ring.
[0007] Based on the above, the wind system caused by the rotation of the fan blades driven by the hub will be blocked by the wind collecting ring to produce a wind collecting effect, and because the thickness of each slope block gradually decreases from the lower periphery to the upper periphery, the multiple slope blocks make the inner wall of the wind collecting ring partially thickened, and each slope block adds a smooth chamfer shape, thereby reducing the area of the air outlet, so as to increase the pressure of the air flow when passing through the fan blades, and can further enhance the air flow aggregation when the fan blade structure blows out, so that the fan blade structure has the advantages of collecting wind and increasing the air output.

[0025] The detailed description and technical content of this creation will be explained below with the help of diagrams. However, the diagrams are for illustrative purposes only and are not intended to limit this creation.
[0026] Please refer to Figures 1 to 4 As shown, the invention provides a pressurized fan blade structure, and the fan blade structure 10 mainly includes a hub 1, a plurality of fan blades 2 and an air collecting ring 3.
[0027] like Figures 1 to 4 As shown, one end of the plurality of blades 2 is connected to the hub 1 and the other end thereof has an outer edge portion 21 , and each blade 2 has a windward surface 22 and a leeward surface 23 opposite to each other.
[0028] like Figures 1 to 4As shown, the air collecting ring 3 is connected to the outer edge 21 of each fan blade 2, and the air collecting ring 3 has a pair of opposite upper edges 31 and a lower edge 32. The inner edge of the air collecting ring 3 and the windward surface 22 of each fan blade 2 are extended with a plurality of slope blocks 33 whose thickness gradually decreases from the lower edge 32 toward the upper edge 31. The inner edge of the air collecting ring 3 forms an inner serrated ring according to the shape of the plurality of slope blocks 33, and the lower edge 32 of the air collecting ring 3 is an inclined annular surface with a thickness gradually increasing from the outside to the inside.
[0029] The detailed description is as follows. Each slope block 33 extends from the lower periphery 32 of the wind collecting ring 3 to the middle of the upper periphery 31 and the lower periphery 32, and each slope block 33 has a connecting end edge 331 connected to the windward surface 22 of each fan blade 2 on one side and a triangular side surface 332 on the other end. There is a spacing S between each triangular side surface 332 and the windward surface 22 of each fan blade 2.
[0030] like Figures 1 to 4 As shown, the use state of the fan blade structure 10 of the present invention utilizes the hub 1 to drive the fan blades 2 to rotate, and the wind system caused by the wind system will be blocked by the wind collecting ring 3 to produce a wind collecting effect. Moreover, since the thickness of each slope block 33 gradually decreases from the lower periphery 32 toward the upper periphery 31, the multiple slope blocks 33 allow the inner wall of the wind collecting ring 3 to be locally thickened, and each slope block 33 is added with a continuous chamfer shape, thereby reducing the area of the air outlet to increase the pressure of the airflow when passing through the fan blade 2, and can further enhance the airflow aggregation when the fan blade structure 10 is blown out, so that the heat dissipation element directly blown by the airflow can obtain a better heat dissipation effect, thereby making the fan blade structure 10 have the advantages of collecting air and increasing the air output.
[0031] In summary, the pressurized fan blade structure of this invention can indeed achieve the intended purpose of use and solve the deficiencies of the prior art. It also has industrial applicability, novelty and progress, and fully meets the requirements for patent applications. Therefore, an application is filed in accordance with the Patent Law. Please carefully examine and approve the patent in this case to protect the rights of the creator.
