AI Technical Summary
Technical Problem
Existing electric fans have low airflow efficiency and high operating noise, mainly due to aerodynamic losses and increased noise caused by the vertical impact of airflow on the motor assembly.
Method used
A flow guide is installed between the diffuser assembly and the support, with the flow guide facing the air outlet to adjust the direction of gas flow, causing the airflow to deflect and split, thus avoiding vertical impact on the motor assembly.
Benefits of technology
The design of the air deflector reduces the impact noise of airflow on the motor components, lowers the operating noise of the electric fan, and improves the gas flow efficiency.
