[Prior Art] The blade I system is roughly divided into four types: (four) wheeled blades and louvered sounds, 、, and k. After actual use, 'there are two kinds of improvement space in the air volume and the system.' 'The louvered blade and the bottom 2 force' are therefore the W-series---radius design, and the Η is right-angled, so the suction of the blade is limited, and the bottom of the right-angled cymbal is more noisy. ^The right-angled leaf; b The inventor developed the wind blade structure improvement of the G9G208310 range hood in China, and obtained the patent right after the actual trial. The patent case was actually tested (4), and the previous two leaf structure rows were sold. There have been significant advances in wind and summer volume, but the inventors have not found that there are still unpainted good things. In particular, the inventors have found that the main part of the blade for intercepting the soot is in the upper half of the blade. Therefore, in order to improve the performance of the blade, it is necessary to improve this feature. The reason is that the inventor has actively worked hard to study, and after many improvements, he has developed the full-time structure of China's Announcement No. 564927, which mainly sets the blades in the "recording state" between the upper seat and the lower ring. And using the upper and lower halves of the blade to form a main and auxiliary leaf portion of the larger and smaller wide area, 1321615 and the blade forms a concave arc, by which the main and auxiliary sides of different widths are adopted. The leaf design is designed to increase the air inlet, increase the amount of smoke and reduce the wind noise, so as to improve the overall performance and practical efficiency. However, the inventors have found that the leaf month of the structure of the Patent No. 564927 is set on the upper and lower ring pieces by the "vertical state", so that the specific surface area of the blade is small, so that the exhaust air volume is not increased to an optimum state. 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.

The main leaf portion (3 4 ) of the gradually larger area forms a convex curvature (3 6 ) between the inner and the auxiliary leaf portions (3 4 (3 5), and then the main leaf portion (3 4), the pair The leaf portion (35) is provided with a plurality of drainage holes (37) extending through both sides. [Embodiment] In the implementation of the present invention, the main and auxiliary leaf portions of different widths are still adopted by the above-mentioned blades (3〇) (3 4 ) ( 3 5 ) Design, with the inner diameter of the lower ring piece (20) increased, the cross-sectional area of the air inlet of the blade (3 〇) can be increased to increase the suction amount of the soot, and through the blade (3 Q) The upper half of the shape, the main lobe (3 4 ) of the larger wide area, according to the increase of the soot interception and suction 'to increase the exhaust volume, while the sub-leaf of the lower half of the blade (3Q) (3 4 ) is an upward extension of the convex curvature (3 6), and can reduce the >, leaf >; (3 Q ) and the soot to generate wind cutting resistance, thereby reducing the noise noise generated by the blade (3 〇) and the soot contact collision The main implementation of the present invention is as follows: 1. The present invention is provided with a drainage hole (37) penetrating both sides of the main leaf portion (34) and the auxiliary leaf portion (35) to make the drainage (3 7 ) has the function of guiding the entry of the soot '俾 to reduce the impedance of the blade (30) during rotation, and can greatly improve the efficiency of the fan in rotation, in addition, the drainage hole (37) can be reduced The problem of direct collision between the blade (3Q) and the soot during rotation is sufficient to effectively reduce noise. 1321615 2. The upper and lower ends of the blade (30) of the present invention are placed in an inclined state and are fixed between the upper dish-shaped seat body (10) and the lower ring piece (20), so that the blade can be enhanced (30). The rigidity of the rotation, and the arrangement can increase the specific surface area of the blade (30), thereby again increasing the efficiency of the rotation of the fan. 3. The bottom end of the shell chamber (12) of the present invention protrudes below the lower ring piece (20), so that the volume of the shell chamber (12) can be greatly increased, so that the motor (40) is fully accommodated. In this way, the volume of the combination of the fan and the motor (40) can be greatly reduced, so that the invention can be installed in the range hood with less space. According to the foregoing, the structure of the present invention is unprecedented, thereby achieving a significant increase in the efficiency and rigidity of the fan in rotation, and minimizing the noise of the fan, which is a highly invented technical concept.
