Please refer to FIG. 5 and FIG. 6 together for another preferred embodiment of the present invention. In the present embodiment, the overall structure and the inter-element relationship are substantially the same as in the previous embodiment. In the present embodiment, the at least two-stage blade group 4 further includes a third-order blade group 43 through which the second-order blade group 42 is different from the previous embodiment. The first-order surrounding piece 412 extends on the upper side of the first-stage blade set 41, and the second-stage blade set 42 is formed on the other side of the first-stage blade set 41 to form a second-order surrounding piece 422. A third-stage blade set 43 is formed on the other side of the surrounding piece 422. The third-stage blade set 43 has a plurality of blades disposed around the blade, and a third connecting portion 431 is disposed between the blades of the third-stage blade set 43. Each of the blades is circumferentially connected via the third connecting portion 431 such that the third-order blade group 43 is annular, and the second-order surrounding piece 422 extends over the outer circumference of the second-stage blade group 42 and extends The second-stage blade group 43 is on the lower side of the outer circumference, and therefore, the third thereof The diameter of the blade group 43 formed by the blade and the third connecting portion 431 is larger than the diameter formed by the second-stage blade group 42 via the blade and the second connecting portion 421, and the diameter of the second-order surrounding piece is larger than the first-order The diameter of the surrounding piece is formed, so that the third-stage blade group 43, the second plate 42 and the first-stage plate group 41 are formed with a combination of different diameters, and at the same time, the blade group* can be seen in the environment in which it is used. The surround and multi-order read sets 4 of different diameters are added differently. Please also refer to Figures 7 and 8 for the purpose of this creation. Μ4:1^25·1 October 18, 101 Correction Replacement Page - The preferred embodiment, in which the display portion 33 of the hybrid hub 3 - a first-stage blade set 41, and the first-order blade set 41 and the second-stage blade set 42 have the first-order surrounding piece 412, the first-order surrounding piece 412 further extending to the first- a lower stage of the step group 41, and the first step surrounding piece 412 extends over the outer circumference of the lower side of the first stage blade group 41 and the other side of the first stage surrounding piece 412 extends the second stage The blade assembly is erected, and its first-order surrounding piece 412 extends over the inner circumference of the upper side of the second-stage blade group 42. Therefore, the second-order blade group 42 and the first-order blade group 41 are formed with a combination of different diameters. The design makes the centrifugal fan 2 of this creation corresponding to the space-constrained or interference of peripheral parts (4), and provides the best flow and wind pressure under the speed of the Kawasaki, achieving the effect of reducing the motor load and reducing noise. This creation is a multi-layer impeller centrifugal fan with the following advantages: L can be installed in a space-constrained use ring 2. It can be installed in the environment where the surrounding parts interfere with each other; 3. It can provide the best flow and wind pressure at the same speed; 4. It can reduce the motor load and reduce. Voice.
