AI Technical Summary

Technical Problem

Existing fans suffer from problems such as low dispensing efficiency, easy glue detachment, cumbersome operation, and insufficient structural stability during dynamic balancing tests, which affect their noise reduction performance and service life.

Method used

A ring array of balancing grooves is set on the periphery of the fan body's receiving cavity and the mounting surface. Combined with a multi-fixing structure of ribs, through holes and snap-fit ​​blocks, the glue is fixed in the grooves, and the stability of the fan frame is enhanced by a multi-connector design.

Benefits of technology

It achieves precise fixation of the glue position, simplifies the operation process, improves the efficiency of dynamic balance testing, reduces vibration and noise, and enhances the stability and overall rigidity of the structure.
