AI Technical Summary
Technical Problem
The working head of existing handheld power tools tends to overheat during use, and because the exposed part is metal, users feel the heat strongly during use, causing inconvenience.
Method used
An optimized airflow design is adopted, using a motor cooling fan to cool the working head away from the machine body through the air outlet. The air outlet is set to face the working head and is symmetrically distributed around the circumference, left and right, and up and down for uniform heat dissipation.
Benefits of technology
It effectively solves the problem of overheating of the working head, achieves uniform heat dissipation of the working head, and improves user comfort.
