New description: [New technical field] [0001] The present invention relates to a device for driving airflow, especially an impeller for an electric fan. [Prior Art] [0002] An electric fan is a relatively common electric appliance in today's society, which has a power unit and an impeller, and the impeller is provided with a plurality of blades; the impeller is rotated by the power unit and is driven by the blades on the impeller Disturbing the air during the rotation and then forcing the flow of the airflow is also known as wind. [〇〇〇3] The wind removal of the electric fan can make the person feel cool, and the air in the space can be circulated to improve the indoor sultry condition. When the electric fan is equipped with cold air, it can assist the air circulation convection. The indoor temperature reaches a stable temperature faster. However, in order to cause the above-mentioned convection and circulation, the wind is required, and in the prior art electric fan, the blades of the impeller cannot concentrate the wind. Referring to FIG. 5 and FIG. 6, the prior art electric fan 90 will rapidly diffuse the blown wind, and the wind will only wrap around the outside, resulting in the central portion _______ no blue, and the wind is dispersed. And it can't effectively shape the convection and circulation; if you want to abandon it and then m-m leaves, this will cause energy waste. [_ In addition, the impeller 91 of the prior art has a small number of blades 911 and a large area. Therefore, the amount of wind driven by each blade 911 is large, and the burden on the power unit is also increased; the power unit is a motor, for example, when the blade 9 is When the burden on the motor is too large, the motor will be noisy and disturb the user. Form No. A0101 Page 3 of 14 M428258 [New content] [0006] In view of the above-mentioned prior art impeller, wind beam diffusion cannot be avoided. The present invention provides an impeller for an electric fan, which can effectively solve the above-mentioned disadvantages. [0007] In order to achieve the above-mentioned creation, the invention is hollow, which leads to insufficient wind power and the disadvantage that the blade is too burdensome for the power device to generate noise. OBJECTIVE: The technical means adopted in the present invention is to design an impeller for an electric fan, which comprises: [0008] a joint portion; [0009] a circulation portion, which is an annular sheet body, and is provided with a joint portion. The circulation portion has an outer ring wall surface and an inner ring wall surface; [0010] a plurality of inner blades disposed around the joint portion and the circulation portion, each inner blade The inner ring wall surfaces of the joint portion and the circulation portion are respectively connected to both sides; [0011] a plurality of outer blades surround the outer ring wall surface of the circulation portion. [0012] The present invention has an advantage in that an annular piece is provided by a circulation portion, and the inner ring wall surface and the outer ring wall surface of the circulation portion are respectively provided with inner blades and outer blades, so that the wind driven by the outer blades is affected by the rotation of the annular circulation portion, and is forced to be concentrated into a bundle The wind driven by the inner blade is wrapped by the wind of the outer blade and can be concentrated in the center; combining the effects of the two blades, the wind can be concentrated while avoiding hollowness, and thus can be blown further. The blade design is divided into inner and outer blades to reduce the area of individual blades, thereby reducing the air volume of individual blades and the burden on the power unit to avoid noise generation, and by increasing the number of blades to maintain the total air volume. In this way, it is possible to effectively concentrate the wind to form convection and circulation, and to reduce the burden on the power unit, and reduce the noise by the form number A0101, page 4 / total 14 pages. [0013] Further, the impeller for an electric fan, wherein the inner blade and the outer blade have the same arc direction. [0014] Further, the impeller for the electric fan, wherein the inner side is adjacent The angle between the blades is greater than the angle between the adjacent outer blades. [Embodiment] [0015] The following is a description of the preferred embodiment of the present invention, and further illustrates the technical means by which the creation is intended to achieve the intended purpose of creation. Referring to Fig. 1, the impeller for an electric fan of the present invention comprises a joint portion 10, a circulation portion 20, a plurality of inner blades 30 and a plurality of outer blades 40. [0017] Referring to Figures 1 to 3, the foregoing The joint portion 10 is a circular sleeve, and one end is provided with a fitting groove 11. [0018] The above-mentioned circulation portion 20 is an annular sheet body, and is provided with a joint portion 10 having an outer ring wall surface 21 and an inner ring wall surface 22. The plurality of inner blades 30 are disposed around the joint portion 10 and the circulation portion 20, and the inner and outer sides of each inner blade 30 are connected to the outer wall surface of the joint portion 10 and the inner ring wall surface 22 of the circulation portion 20, respectively. - _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The directions are the same, and the angle between adjacent inner blades 30 is larger than the angle between adjacent outer blades 40. [0021] Referring to FIG. 1 and FIG. 4, in the embodiment, the fitting groove 11 of the joint portion 10 can be engaged with the power device of the electric fan, for example, the rotating shaft of the motor; The inner ring form 30, the inner blade form number A0101, the fifth inner blade form number A0101, the fifth outer plate 40 and the outer blade 40 are rotated, and the inner and outer blades 30 and 40 are rotated by the inner and outer blades 30 and 40. The arc shape itself can force the airflow to flow to form the wind, and the wind driven by the outer blade 40 is affected by the rotation of the annular circulation portion 20, and is forced to concentrate into a bundle inward, and the wind driven by the inner blade 30 is externally received. The wind wrapping of the blades 40 can be concentrated in the center; combining the effects of the two blades 30, 40, the wind can be concentrated while avoiding hollowness, and thus can be blown further. In addition, by dividing the blade design into the inner blade 30 and the outer blade 40, the area of the individual blades 30, 40 can be reduced, thereby reducing the air volume of the individual blades 30, 40 and the burden on the motor to avoid noise generation, and by lifting The number of blades 30, 40 is maintained to maintain the total amount of air. The present invention achieves the purpose of effectively collecting ten winds to form convection and circulation, and reducing the burden on the motor to reduce noise.
