AI Technical Summary
When the wind turbine rotates, local vortices in the negative pressure zone cause wind energy loss and reduce the efficiency of the motor in working on the wind turbine.
Design a wind turbine assembly including a guide section located in the central region of the wind turbine assembly with its axis extending axially to fill the negative pressure cavity and guide the airflow to the outlet side, thereby reducing the generation of local vortices.
By reducing local vortices in the negative pressure cavity, the efficiency of the motor's work on the impeller and the air delivery efficiency are improved, thereby enhancing the overall purification efficiency of the machine.
