Description

M279748 8. Description of the new type: [Technical field to which the new type belongs] This creative system is a type of ceiling fan blade structure with a large amount of wind, especially a technical field applied to ceiling fan components. [Prior art] As shown in the fifth figure, the blade of the white-headed ceiling fan of Takimiya, the blade body (the flat end of the blade system is connected to the ceiling fan blade frame 叶), and the ceiling fan blade combined with the blade body ⑽ The combination of the frame 再 'and _ ⑽ is combined with the action of the secret device (30), which simultaneously drives the blade body to rotate. However, although the private leaf-like structure can achieve its existing effects, there are still disadvantages. Such as ... "1. Because its material is flat," When _ Shi Pingyu Ye 4 is subject to strong wind, so-the power consumed by the blade rotation is large. 2. Because the blade is flat, it does not meet the design concept of fluid mechanics, so the amount of wind it generates is small. [New content] <Creative motivation> In view of the above problems, in order to improve the problem of large wind resistance and small wind setting of the fan blades of the conventional fan, the author has completed the creation of a ceiling fan blade structure with large air volume. <Creation Purpose> The purpose of this creation is to provide a ceiling fan blade structure that effectively lowers the wind to achieve low resistance and large air volume. 5 M279748 »[Implementation Modes] In order to allow your reviewers to further understand the structure, characteristics and other purposes of this creation, the following preferred embodiments are attached with detailed illustrations as follows, but the implementation described in this illustration The examples are for illustrative purposes and are not the only restrictions on patent applications. * Please refer to Figures 1-3 for the three-dimensional and cross-section schematic diagrams of the ceiling fan blade structure with large air volume, which contains ... a blade body ⑽, which has -the -end (11) A second end 1⑽, and the first end (11) is provided with a plurality of fixing holes (⑽), and the bottom surface of the second end ⑽ is provided with a windward surface (120), and a bulge is provided above the windward surface (120). ⑽); Through the cooperation of the above structure 'to complete this creation, it has a ceiling fan blade structure with large air volume. -Please refer to Figures 2 and 3 for a cross-sectional view of the structure of the ceiling fan blades that generate a large amount of air. The first end (11) of the blade body (10) is flat and the other end (12) Both sides are at the same height as the first end 〇1), and the windward surface (120) of the middle part bulges, the windward surface (120) forms an angle θ with the plane, and the angle θ is 15. ~ 20. In between, if the included angle 0 crosses 20. Above, the wind resistance of the blade body will increase accordingly, so the air volume will become smaller. Please refer to the fourth figure for reference. This is a reference drawing of the state of use of the ceiling fan blade structure that generates large air volume. The flat surface of the blade body (the first end ⑴) is combined with the ceiling fan blade holder ⑽). The second end of 10) (⑵ is on both sides equal to the first end (11), and the upwind side (120) of the middle part is raised, so when the blade body (10) rotates, the upwind side (120) produces a relatively The flow curve of the better, resulting in a large air volume, and a small resistance to the leaf 6 M279748 sheet (10). In summary, this creation can indeed achieve the above functions and purposes, so this creation should meet the patent application requirements, 爰The application is submitted according to the law. [Schematic explanation] The first picture is a schematic view of the three-dimensional state of the creation. The second picture is a side view of the creation. The third picture is a view of the section before the creation. The reference drawing of the use status of the creation. The fifth drawing is the reference drawing of the customary status of the creation.
