Description

Technical Field

[0001] This utility model relates to the field of fan blade technology, and in particular to a fan blade structure. Background Technology

[0002] Existing fan blades consist of a cutting element and an air supply element, with the air supply element being a downward-sloping plate. The angle of this slope is related to the air volume delivered, but the greater the downward angle, the lower the strength of the plate. Therefore, there is an urgent need for a fan blade structure to address the strength difference in existing air supply elements as the slope angle increases. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a fan blade structure that can improve the strength of the fan blade.

[0004] A fan blade structure designed for this purpose includes a mounting component, a cutting component, an air supply component, and a connecting component;

[0005] The air cutting component, air supply component, and connecting component are arranged sequentially along the rotation direction, and the air cutting component and the connecting component are both fixedly mounted on the mounting component;

[0006] The air supply component is connected to the air cutting component, and the air cutting component is inclined downward from the side closer to the air supply component to the side closer to the connecting component.

[0007] The connector is provided with several reinforcing ribs and is connected to the air supply component.

[0008] Preferably, the lower surface of the mounting component forms an angle A with the air supply component;

[0009] An angle B is formed between the lower surface of the mounting component and the connector.

[0010] The included angle A is greater than the included angle B.

[0011] Preferably, the included angle A is 3° to 80°;

[0012] The included angle B = 3° to 80°.

[0013] Preferably, the included angle A is 5° to 45°;

[0014] The included angle B is 5° to 45°.

[0015] Preferably, both ends of the air-cutting component and the connecting component are provided with reinforcing members that are connected to each other, and the air-supplying component is disposed between the two reinforcing members.

[0016] Compared with the prior art, this utility model places the air supply component between the air cutting component and the connecting component, and then connects the connecting component with the air supply component with the help of the reinforcing rib. This design can not only strengthen the overall strength of the fan blade, but also reduce the weight of the fan blade as much as possible with the help of the reinforcing rib to meet the usage requirements.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-6 A fan blade structure includes a mounting component 10, a cutting element 20, an air supply element 40, and a connecting component 30. The cutting element 20, the air supply element 40, and the connecting component 30 are arranged sequentially along the rotation direction. The cutting element 20 and the connecting component 30 are both fixedly mounted on the mounting component 10. The air supply element 40 is connected to the cutting element 20, and the cutting element 20 is gradually inclined downward from the side closer to the air supply element 40 to the side closer to the connecting component 30. The connecting component 30 is provided with several reinforcing ribs 50 and is connected to the air supply element 40. In this embodiment, the air supply element is placed between the cutting element and the connecting component, and then connected to the air supply element by the connecting component in conjunction with the reinforcing ribs. This design not only strengthens the overall fan blade strength, but also, with the help of the reinforcing ribs, minimizes the weight of the fan blade to meet usage requirements.

[0025] See Figure 6 An angle A is formed between the lower surface of the mounting component 10 and the air supply component 40; an angle B is formed between the lower surface of the mounting component 10 and the connecting component 30; and the angle A is greater than the angle B.

[0026] Furthermore, the included angle A = 3° to 80°; the included angle B = 3° to 80°.

[0027] Preferably, the included angle A = 5° to 45°; the included angle B = 5° to 45°.

[0028] See Figure 1 The air-cutting component 20 and the connecting component 30 are both provided with reinforcing members 60 that are connected to each other. The air supply component 40 is disposed between the two reinforcing members 60, which can effectively strengthen the strength of the air-cutting component 20 and the connecting component 30 and improve the overall strength.
