[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Example

[0019] like Figure 1 , 2 As shown, a high-performance fan includes: an air guide assembly, a drive assembly 5, and a cover 6. The air guide assembly includes: an air guide shroud 1, a moving impeller 2, a first fixed impeller 3, and a second fixed impeller 4. The second fixed impeller 4 is fixedly disposed on the side of the first fixed impeller 3 near the moving impeller 2. One side of the first fixed impeller 3 is screwed to the drive assembly 5 and the cover 6, and the other side of the first fixed impeller 3 is snapped into the air guide shroud 1. The drive assembly 5 is disposed on the cover 6. The moving impeller 2 is disposed between the air guide shroud 1 and the second fixed impeller 4 and is connected to the power output end of the drive assembly 5.

[0020] like Figure 4As shown, the first fixed impeller 3 includes: a first inner support body 31, an outer support body 32, and a plurality of first guide vanes 33 disposed between the first inner support body 31 and the outer support body 32. The plurality of first guide vanes 33 are arranged in a ring array with the axis of the inner support body as the center, and each first guide vane 33 is inclined.

[0021] like Figure 5 As shown, the second fixed impeller 4 includes: a second inner support body 41 and a plurality of second guide vanes 42 disposed on the outer wall of the second inner support body 41. The plurality of second guide vanes 42 are arranged in a circular array with the axis of the second inner support body 41 as the center, and each second guide vane 42 is inclined.

[0022] The number of first guide vanes 33 is greater than the number of second guide vanes 42, and the tilt angle of the first guide vanes 33 is greater than the tilt angle of the second guide vanes 42. When the fan is operating, external air is drawn in by the rotating passive impeller 2, passes sequentially through the second fixed impeller 4 and the first fixed impeller 3, and is then blown out. The flow channel between the second guide vanes 42 is wider, and the tilt angle of the second guide vanes 42 is smaller, which guides the airflow in quickly to improve the vacuum level. The flow channel between the first guide vanes 33 is more densely arranged, and the tilt angle of the first guide vanes 33 is larger, which can quickly divert the high-speed passing gas and reduce wind noise. Through the cooperation of the first fixed impeller 33 and the second fixed impeller 42, the fan performance can be effectively improved.

[0023] like Figure 3 As shown, the impeller 2 includes: a pad plate 21, an arc-shaped top plate 22, and a plurality of blades 23 disposed between the pad plate 21 and the arc-shaped top plate 22. The pad plate 21 has a main shaft hole in the center for connecting to the power output end of the drive assembly 5. The blades 23 are arranged in a ring array around the center of the pad plate 21 at the edge of the pad plate 21. The arc-shaped top plate 22 has an air inlet in the middle.

[0024] like Figure 1 As shown, the drive assembly 5 includes: a stator 51, a rotor 52, a stator base 53, and a drive control board 54. The stator base 53 is screwed and fixed to the first stator impeller 3 and the cover 6 respectively. The stator 51 is mounted on the stator base 53. The rotor 52 passes through the stator 51. The part of the rotor 52 located inside the stator 51 is provided with a magnet 55. The power output end of the rotor 52 passes through the opening on the waterproof shell and is connected to the moving impeller 2. The drive control board 54 is mounted on the stator base 53 and is electrically connected to the coil inside the stator 51. It provides the required working current to the coil inside the stator 51 to generate a magnetic field, thereby driving the rotor 52 with the magnet 55 to rotate.

[0025] The beneficial effect of this utility model is that, compared with conventional products, the high-performance fan of this utility model can significantly improve the vacuum degree and reduce air noise in the same volume, so as to meet higher usage requirements.
