[0024] Currently, a rectifier device is set at the air outlet, and the air outlet is divided into multiple small air outlet areas by multiple dividing strips. However, the existing rectifier device has poor rectification ability and a complex structure. In order to solve the above problems, an embodiment of the present application provides a fan rectifier device, which enhances the rectification effect by setting a double-layer rectification structure and has a simple structure.

[0025] like Figure 1 As shown, the direction indicated by the arrow is the air outlet direction. The fan rectifying device provided in the embodiment of the present application includes a fan body 10. The air outlet of the fan body 10 is sequentially provided with a first rectifying structure and a second rectifying structure. The first rectifying structure and the second rectifying structure are connected to the air outlet; Figure 2 As shown, Figure 2 This is a structural schematic diagram of the first rectification structure. The first rectification structure includes an air guide ring 20, which is used to be fixed on the air outlet. The size of the air guide ring 20 is the same as the size of the air outlet. The air guide ring 20 extends along the air outlet direction. A wind shield block 24 is provided in the air guide ring 20. The wind shield block 24 and the air guide ring 20 are connected by multiple air guide plates 23. The multiple air guide plates 23 are evenly distributed around the wind shield block 24, and the air guide plates 23 extend along the air outlet direction; the second rectification structure includes a rectification plate 35, and multiple air outlet holes 31 are formed in the rectification plate 35. The multiple air outlet holes 31 extend along the air outlet direction.

[0026] The first rectification structure is fixed by the first connecting blocks evenly arranged on the air guide ring 20 and the fan body 10. The fan body 10 is provided with a second connecting block corresponding to the first connecting block on the air guide ring 20 on the side facing the first rectification structure. The first connecting block and the second connecting block are provided with fixing holes 22. The connecting parts pass through the fixing holes 22 on the first connecting block and the second connecting block in sequence to fix the air guide ring 20 and the fan body 10.

[0027] In the embodiment of the present application, the plurality of air guide plates 23 divide the area within the air guide ring 20 into a plurality of air outlet areas to reduce turbulent airflow and direct the air outlet of the fan body 10 toward the outlet direction.

[0028] Specifically, the shape of the air outlet 31 is honeycomb, circular or polygonal, and the air outlet 31 plays a rectifying role, making the airflow more stable and smooth. Figure 3 As shown, the air outlet 31 of the rectifying plate 35 in the embodiment of the present application is in a honeycomb shape.

The wind shield 24 is used to shield the rotating shaft of the fan, thereby improving the rectifying capability.

[0030] Specifically, such as Figure 4 As shown, a fixing ring 30 is provided around the rectifier plate 35. The fixing ring 30 is used to be fixed on the air guide ring 20. A buckle 32 is provided on the fixing ring 30. The buckle 32 is provided at the edge of the fixing ring 30 and extends toward the fan body 10.

The buckle 32 and the locking hole 21 match to fix the air guide ring 20 and the fixing ring 30. The buckle 32 is elastic. When the protrusion 33 is locked in the locking hole 21, the buckle 32 can be pushed out of the locking hole 21 by pressing the protrusion 33. For installation and fastening, the embodiment of the present application is provided with a plurality of evenly distributed buckles 32 on the fixing ring 30.
