New description: Especially a kind of fan blade is more. [New technical field] This is a multi-blade fan rotor with a fan rotor and better performance. [Prior Art] With the advancement of technology, many of the discards and Gan θ have a tendency to be light and short in the I, and the fans used in the heat dissipation are also getting smaller and smaller. The miniaturization of the technical products of the mouth should be made of plastics, so the trend of miniaturization is that the thickness of the blade of the fan rotor is getting thinner and thinner, and the difficulty of forming the plastic is improved. The blade is thinned in thickness: the structural strength is reduced. (4) The fan rotor is unable to bear the wind resistance at the high speed operation, and the blade is easily broken, and the operating efficiency of the fan rotor is lowered. In order to overcome the difficulty in forming the blade of the conventional plastic made by the plastic and the structural strength I, the creator has designed a fan blade which is formed by stamping the fan rotor with a metal piece, and the fan rotor includes a rotor seat and a tight fit. a hub fixed to an outer peripheral surface of the rotor seat, a blade seat, a shaft hub and a rotating shaft, wherein the blade seat includes a cover plate and a plurality of metal blades on a periphery of the cover plate, and the cover plate is fixed to the hub The top surface of the shaft seat is riveted together by the shaft seat, and the top end of the shaft is inserted on the shaft seat, thereby forming a fan rotor. However, the fan rotor made of the above metal sheet can improve the shortcoming of the fan rotor made of plastic. However, in the form of metal sheet fan blade forming, the M331590 is limited by the forming technology, and the number of blades of the blade is reduced.接·5Γ Γ / 士: ny a 〗 〖Restricted 'can not be like plastic clothes fan leaves can form more than a few leaves ^ Μ Μ 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 In addition, in addition to the wind, 芸I wants to be old, h Ί褥 thousand's running efficiency is reduced, and the right 疋 from "the number of blades of the fan blade, due to the limitation of stamping forming - the area of the cymbal will be "丄Therefore, the increase in airflow efficiency driven by a-hai fan blade will also reduce the operating efficiency of the fan rotor. ' [New content] _ The main purpose of this creation is to provide a multi-blade fan rotor. This design is designed to improve the operating efficiency of the conventional fan rotor and improve the fan flow that can be driven by the fan rotor, thereby improving the heat dissipation function of the fan. .

A gap is provided between each adjacent two bent portions, and the outer outer blades are respectively provided The inner side of the bent portion is laterally extended; the inner blade body of the metal sheet is equal to the outer blade seat, and includes an inner seat body and a plurality of inner blades, the inner seat body includes an inner cover plate and The plurality of bent portions are spaced apart from the periphery of the inner cover plate and extend downwardly, and any two of the bent portions are provided with a concave portion extending to the inner cover, and the inner blades are laterally extended from the side of each bent portion. The inner seat of the blade seat is disposed in the outer seat body, and the inner blades respectively pass out of the outer seat from the hollow portions, and the bent portions of the outer blade seat are respectively engaged in the recesses So that the inner and outer blades are staggered 'and the bent portions of the inner and outer blade seats are all on the same circumference; M331590 Member 'm lines to the outer housing assembled with the fixed blade; and a rotating shaft fixed to the top end thereof inserted in the fixed member. In summary, the multi-blade fan rotor of the present invention increases the number of blades by the combination of the inner and outer blades: and does not need to reduce the area of the outer blades to increase the number of blades. Therefore, the multi-f-chip fan rotor can increase the air flow that can be driven during operation, and improve the operating efficiency of the J, thereby improving the heat dissipation capability of the fan.

One of the outer fan blade seats (1) is a member formed by a metal sheet, which comprises an outer seat body (! 〇) and a plurality of inclined outer blades (丄2), the outer seat " ;1 〇)包^ has an outer slab (1 1 ) and several bends (1 3 ) #中'the bend 胄(丄3 ”a1 is arranged on the periphery of the outer cover (1 1 ) and Extending downwardly, the outer seat body (working raft) is formed with an opening facing downwards. Each of the two adjacent bending 胄 (i 3) is provided with: a hollow portion (1 5 ) The blades (1 2 ) extend laterally from the sides of each of the bent portions (1 3 ), and an outer fixing hole (1 4 ) is disposed at the center of the outer cover (丄丄). The seat (2) is a member formed by the metal sheet and has an inner body (2 turns) and a plurality of tilting pieces (2...the inner seat body (20) is included with the outer blade seat (1). There is an inner cover (2 1 ) and a plurality of bent portions (23), and the bends In the above-mentioned (3 3) preferred embodiment towel, the top of the fixing member is inserted into the shaft hole (3 3 ) of the solid member (3 Q ). The inner and outer fan blade seats (two-piece stamping and forming, so the Taimu plant) are white-made Mengzi tablets. The machine-made high-grade Μ creates the same strength as the conventional metal-made fan rotor structure, and also improves the conventional T ^ The structural damage caused by the multi-fan rotor at high speed. The above-mentioned 'multi-blade fan of this creation, Han, 〇, and the inner rotor's outer blade seat (2, 1) are set together The inner and outer blades (22) are alternately arranged in a staggered manner, and then the inner and outer blade seats (2, 1) are assembled by fixing portions (3:) of the fixing member (30), the rotating shaft (4) The top end of the 〇) is inserted into the shaft hole (33) of the fixing member (30), and thus combined into a multi-blade fan rotor. As shown in the fifth and sixth figures, in the second preferred embodiment of the present invention The inner blade seat (2) can be further provided with a sleeve (5 〇) in the inner seat body (2 〇). The sleeve (50) has a top plate (5 work), and the top plate (5) 1) the peripheral edge extends downwardly to the peripheral wall (52), and the top plate (5 1 ) is provided with a perforation (5 3 ) corresponding to the inner fixing hole (25), wherein, due to the inner and outer fan blades The bent portions (23, 13) of (2, 1) are all located on the same circumference, so that the outer side of the peripheral wall (52) is attached to the bent portions (23, 13), thereby stabilizing the group Connected together, the fixing member (30) penetrates the through hole (53), and the sleeve (50) is assembled and fixed in the combination of the inner and outer blade holders (2, 1). The strength of the seat structure of the fan rotor is reinforced by the sleeve (50). As shown in the seventh and eighth embodiments, in the third preferred embodiment of the present invention, an inner ring body (20) of the fan blade seat (2) of the M331590 can be further provided with a ring-shaped magnetic ring (60). On the inner side, since the bent portions (23, 13) of the inner and outer blade holders (2, 1) are all located on the same circumference, the magnetic ring (60) and the bent portions can be increased (2 3 The contact areas of 1 and 3 are attached to each other so that when the fan rotor rotates, the magnetic ring '(60) can be stably driven to rotate. In summary, the multi-blade fan rotor of the present invention can increase the number of blades to more than the conventional metal fan rotor by the combination of the inner and outer blade seats (2, 1) of the same diameter, and The area of the blades can still be maintained as a conventional metal fan rotor, and the area of the blades can be reduced in the process because the number of the blades is increased, so that the number of the blades can be increased, such as a conventional plastic fan. The rotor, so the multi-blade fan rotor of the present invention has the advantages of a large number of blades, a small blade area, and a firm structure. Therefore, the fan rotor can improve the air flow driven during operation, thereby improving the heat dissipation of the fan. efficacy.
