AI Technical Summary

Technical Problem

Existing drilling tools face challenges in preventing dust from entering the tool and efficiently collecting it, as dust can easily enter the tool despite existing dust collection systems.

Method used

A power tool design featuring a detachable dust collector with an elastic passage part that includes a drilling tool mounting mouth part and a storage part mounting mouth part, which press against the tool and storage part respectively, forming air passages that guide dust-laden air to a storage part for separation and collection, while preventing air leakage.

Benefits of technology

The design effectively prevents dust from entering the drilling tool by guiding dust-laden air to a storage part for separation, ensuring efficient air flow and dust collection, thereby enhancing the tool's operational cleanliness and efficiency.
