Technical Field

[0001] The utility model relates to the field of flow balancing structures, in particular to an air outlet flow balancing structure of a fan filter unit. Background Art

[0002] A fan is a device used to generate airflow or wind, usually consisting of a motor, an impeller, an air duct and a casing. The fan drives the impeller to rotate through an electric motor, thereby generating airflow or wind. Fans can be divided into different types according to their purpose and structure, including centrifugal fans, axial flow fans, and mixed flow fans. During the air outlet process, the fan usually needs to use a corresponding flow balancing structure to make the air flow out evenly. The existing flow balancing structure, during use, usually uses multiple air guide blocks to fold against each other, so as to disperse and evenly distribute the air blown out by the fan. This flow balancing method makes it easy to lose a large amount of air volume, resulting in low efficiency of the fan. Therefore, we propose a fan filter unit air outlet flow balancing structure to solve the above-mentioned problems. Utility Model Content

[0025] When working, the staff first inserts the other end of the connecting square tube 204 into the air inlet slot 107, and then passes the fixing bolt from the primary mounting hole 109 through the secondary mounting hole 203, thereby connecting the flow equalizing component 2 with the air duct square tube 101, and then connects the other end of the air duct square tube 101 to the air outlet of the fan, and then the staff inserts the fixed square tube 301 into the air outlet slot 104, thereby connecting the diffuser component 3 with the air duct square tube 101 into a whole.

[0026] When the fan is blowing, when the wind from the fan passes through the impurity adsorption rack 206, floating objects in the air are adsorbed by the impurity adsorption rack 206, thereby improving the purity of the air. At the same time, when the wind blown by the fan flows in the flow-equalizing square tube 201, the multiple groups of flow-equalizing holes 205 separate the wind into multiple strands. When multiple wind beams pass through the air duct square tube 101, the multiple groups of guide grooves 106 guide the air so that the wind beams are blown toward the scattered flow component 3.
