Abstract
Description
Technical Field
[0001] This utility model relates to the field of axial flow fan technology, specifically to an airflow balanced axial flow fan. Background Technology
[0002] Axial flow fans have a wide range of applications. They are fans that direct airflow in the same direction as the fan's axis, such as electric fans and air conditioner outdoor unit fans. They are called "axial flow" because the gas flows parallel to the fan's axis. Axial flow fans are typically used in applications requiring high flow rates but low pressure. An axial flow fan is fixed in position and moves air. It mainly consists of a fan impeller and a casing; its structure is simple, but the specifications required are very high.
[0003] Axial flow fans use a motor to drive an impeller to rotate, causing air to flow parallel to the axis of rotation, thus achieving efficient ventilation. However, axial flow fans may generate turbulence during airflow adjustment, resulting in noise and vibration. This vibration can lead to instability and reduce operating efficiency, causing additional friction between the fan blades and the fan body, requiring the fan to consume more energy to maintain normal operation. Utility Model Content
[0004] To address the above deficiencies, this invention provides an axial flow fan with balanced airflow to solve the turbulence problem in axial flow fans.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: An airflow balancing axial flow fan, comprising Axial flow fan; The connector is installed at the air outlet of the axial flow fan; The rotating ring is movably mounted on the outside of the connector, and the connector is equipped with a drive mechanism to drive the rotating ring to rotate. Connecting rod 1 consists of several components, evenly installed on the outside of the rotating ring; Link 2 consists of several links, which are movably inserted into the outside of the connector and are arranged opposite to several links 1; Several connecting plates are installed at the front end of several connecting rods. There are several strip holes, which are opened on several connecting plates, and the front end of several connecting rods is respectively inserted into the corresponding strip holes; Several air regulating plates are installed at the inner ends of several connecting rods. Several guide plates are evenly installed on the front end of the inner wall of the connector. The flow guide net is fitted onto several flow guide plates.
[0006] Furthermore, the drive mechanism includes a circular slide rail fixedly mounted on the outside of the connector, a rotating ring movably mounted on the circular slide rail, and a push plate mounted on the rotating ring. An electric actuator is hinged to the connector, and the telescopic end of the electric actuator is hinged to the push plate. When the telescopic end of the electric actuator extends, it can drive the rotating ring to rotate clockwise through the push plate. Conversely, when the telescopic end of the electric actuator retracts, it can drive the rotating ring to rotate counterclockwise through the push plate.
[0007] Furthermore, several air regulating plates are fan-shaped, and adjacent groups of air regulating plates fit together, making it easy for several air regulating plates to close or open.
[0008] Furthermore, several guide vanes are arranged in a triangular shape, and a guide net in a conical shape is fitted onto several guide vanes to adjust the distribution of airflow and achieve the purpose of guiding airflow.
[0009] Furthermore, the axial flow fan includes an electric motor fixed to the rear end of the axial flow fan by a bracket, a rotor installed at the rotating end of the electric motor, and several blades fixed on the rotor. The electric motor drives the several blades to rotate through the rotor, so that the air flows in a direction parallel to the rotation axis, thereby achieving efficient ventilation.
[0010] Furthermore, a set of triangular brackets are installed on both sides of the axial flow fan for easy support.
[0011] This utility model provides an axial flow fan with balanced airflow, which has the following beneficial effects: by driving the rotating ring to rotate, several connecting rods can be rotated, which in turn can drive several air regulating plates to deflect, thereby achieving the purpose of adjusting the air volume of the axial flow fan. In conjunction with the guide net and several guide plates, the airflow is made more stable, reducing turbulence and lowering fan noise and vibration. Attached Figure Description

Conversely, when the telescopic end of the electric actuator 13 retracts, it can drive the rotating ring 3 to rotate counterclockwise through the push plate 12.
[0018] In some embodiments, a plurality of air regulating plates 8 are fan-shaped, and adjacent groups of air regulating plates 8 fit together, such as... Figure 2 As shown, this facilitates the closing or unfolding of several air regulating plates 8.
[0019] In some embodiments, a plurality of guide plates 9 are triangular in shape, and a guide net 10 is conically fitted onto the plurality of guide plates 9 to adjust the distribution of airflow and achieve the purpose of guiding airflow.
[0020] In some embodiments, the axial flow fan 1 includes a motor 15 fixed to the rear end of the axial flow fan 1 by a bracket 14, a rotor 16 mounted on the rotating end of the motor 15, and a plurality of blades 17 fixed on the rotor 16, such as...
