Description of the invention: [Technical field to which the invention pertains] b The invention relates to a fan blade structure, and in particular to an innovative design of a blade which can greatly enhance the wind and reduce the amount of noise. [Prior Art] Conventional range hood blades are roughly divided into two types: turbine blades and louver blades. However, after actual use, it is found that the two types are greatly improved regardless of the amount of exhaust air and the amount of noise. The louver leaf # 借 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In view of this, the inventors have developed China's application No. 090208310, "Improvement of the structure of the hood of the range hood", and the financial auditor shouted that the full-time professional test proved that the thief volume and noise amount of the previous _ wind blade structure In terms of slavery, there is no such thing as self-satisfaction, and it is found that there are still unsatisfactory perfections. In particular, I have found that the main part of the blade used to intercept the oil fume is in the upper half of the blade. Therefore, in view of the leakage of the system, it is necessary to improve this feature. , 疋 'The inventor is actively working hard to study, after many improvements, so, I will go out of China to sue 2564927, the main store (8) with "vertical =" set on the upper dish and the only (four) And _^ upper and lower half of each of the larger and smaller wide area of the main and auxiliary leaves, and the blade forms a concave degree of the degree, by turning (four) Ke Ru size of the main, the Ministry of materials , can make 5 200819640 air inlet increase, can increase the amount of smoke and reduce wind noise, according to performance and practical effects. However, the inventor of the present invention found that the blade of the structure of the patent No. 564,927 has been erected on the upper and lower sides of the seat by the "history state", and the contact surface area of the Qing is small, so that the exhaust air cannot be increased to the balance. In addition, the wind-cut noise cannot be minimized. Therefore, it is still necessary to improve it. Therefore, the present invention has been developed to cope with it. SUMMARY OF THE INVENTION In order to enable the reviewing committee to further understand the structure, features and other purposes of the present invention, the eye-catching cake is as follows: Please refer to the first and sixth figures, the fan of the present invention is mainly An upper disc piece (1 〇) under the % < piece (2 0) and a number of radially curved blades (3 〇); ^ f upper dish (1 〇) top surface has - The outer ring portion (1i) and the cylindrical portion of the central portion of the oblique soil portion (ii) are pinned to a cylindrical cavity (1 冓, the outer ring portion (11) is equally divided at the outer edge and the outer position If there is a "" 'day (13) (14), and the two (two) corresponding slot (1 3 ) (1 4) direction f is different, as for the shell chamber (12) can provide a motor (4 0) accommodating, the center of the chamber (! 2), the position of the bottom _ (1), to provide the horse's spindle (4 1) into the 'and by the bolt (16), the upper disc The seat body (1 Q ) (10) is rotated by the motor (40) main shaft (4 1 ), 6 200819640 The lower ring piece (20) is symmetrical to the outer edge position of the outer ring portion (1 1), and Higher than the bottom end of the shell chamber (12), 俾 it with the upper dish Between the (1 〇), a ring-shaped accommodating space is formed, and the lower ring piece (2 〇) is provided with a fitting groove (21) at a position opposite to the upper dish-shaped seat (10) slot (13); a plurality of blades (30), the device of equal division is formed in an annular belt-shaped accommodation space formed between the upper dish (1 〇) and the lower ring (20), and the blade (3 〇) is composed of two The different circular diameters are formed so that the outer peripheral edge of the blade (3 〇) is larger than the inner circumference, and the outer circumference of the blades (3 〇) does not protrude from the upper dish (i 〇) and the lower cymbal ( 2 0) outer diameter, and the top end of the blade (3 Q) is provided with a plug (3 1 ) ( 3 2 ) which can be clamped to the corresponding slot (1 3 ) (1 4 ), and the bottom end is provided There is an insert (3 3 ) which can be fixed on the corresponding recessed groove (2 1 ), and the upper and lower ends of the blades (3 〇) are fixed in an inclined state on the upper dish (i) 〇) and the lower ring piece (20); the upper and lower half of the blade (3 〇) respectively form a larger wide area of the main leaf portion (34) and a smaller wide area of the auxiliary leaf portion ( 3 5 ), the inner end of the inner peripheral edge of the auxiliary leaf portion (35) protrudes from the inner diameter of the lower ring piece (2〇) And extending upward and inwardly, forming a gradually larger main leaf portion (3 4 ) in the middle portion of the blade (30), and forming a space between the inner circumferences of the main and auxiliary leaf portions (34) (35) The convex curvature (3 6 ) is then provided with a plurality of drainage holes (37) passing through both sides of the main leaf portion (34) and the auxiliary leaf portion (35). [Embodiment] In the implementation of the present invention, the blade (30) is further designed with different widths and sizes 200819640: the main and auxiliary leaf portions (3 4 ) (3 5 ), and the lower ring piece (2 〇) The inner diameter is increased; the larger 1^ can increase the cross-sectional area of the air inlet of the blade (3〇) to enhance the suction of the soot 1' and the upper half of the blade (3 〇) to form a larger wide area of the main leaf (3 4 ) 'According to increasing the interception and suction of the soot to increase the exhaust volume, while the sub-leaf (3 4) of the lower half of the blade (30) extends upwards with a convex curvature (36). The utility model can reduce the wind cutting resistance of the system (3 〇) and the soot, thereby reducing the noise noise generated by the blade (30) and the soot contact collision, so as to achieve the effect of noise reduction, the main implementation of the invention lies in The invention is provided with a drainage hole (37) penetrating both sides of the main leaf portion (34) and the auxiliary leaf portion (35), so that the drainage hole (37) has the function of guiding the entry of the soot, and the lowering of the blade (3) Q) In the impedance of _, the city greatly increases the efficiency of the rotation 7, in addition to the 'drainage hole (3 7) and can reduce the blade (3 (1) in the knowledge and The direct collision problem between the fume is sufficient to effectively reduce the noise. - The upper and lower ends of the blade (30) of the present invention are placed in an inclined state and are fixed on the upper dish (1 〇) and the lower ring piece. Between (2 ◦), it is possible to increase the rigidity of the blade (3 〇) during rotation and these settings can increase the specific surface area of the blade (3 (eight)' to increase the efficiency of the rotation of the fan again. 12) The bottom end protrudes to the lower ring piece (2〇), which can greatly increase the volume of the shell chamber (i 2), so that the motor u 〇) can be fully accommodated therein, thus greatly reducing the fan and the motor. (4 〇) the volume 'to make the invention less empty _ crack in the range hood., ... mouth 200819640 - According to the foregoing, the structure of the present invention is indeed unprecedented, and thus achieve a substantial increase in wind. The efficiency and rigidity of the rotation, and the noise of the fan can be minimized. It is a high-invention of the technical concept, and should meet the requirements of the patent application, and apply in accordance with the law. One preferred embodiment, when not limited to the present invention凡范®, ie, the equivalent changes and modifications made by the patent in accordance with this patent, should still fall within the scope of the present invention.
