AI Technical Summary

Technical Problem

The dust collection devices in existing grinding tools increase the size and weight of the main unit, making operation inconvenient. In particular, dust collection may affect the stability of the main unit's center of gravity, causing the operation to wobble.

Method used

The dust collection system is integrated into the main body housing of the polishing tool. The dust is collected into the hollow cavity of the handle through the fan assembly and dust exhaust assembly, which avoids the need for an additional dust collection container and reduces the size and weight of the main body.

Benefits of technology

While achieving dust collection, it avoids increasing the size of the main unit, improves operational flexibility and stability, and enhances the user experience.

Abstract

The application discloses a polishing tool, comprising: a bottom plate assembly, comprising a bottom plate and a polishing piece fixed on the bottom plate, and a dust suction port provided on the bottom plate assembly; a casing assembly arranged on the bottom plate and comprising a main casing; a driving mechanism arranged in the main casing and configured to drive the bottom plate assembly to move; the casing assembly further comprises a holding part casing, the holding part casing comprises an inlet and an outlet arranged thereon, a hollow cavity is formed in the holding part casing and communicates with the inlet and the outlet, the inlet communicates with the dust suction port, and the outlet is configured to discharge gas in the cavity; and a fan assembly comprising a dust discharging fan blade, the dust discharging fan blade is used to form a wind path moving from the dust suction port to the inlet. The polishing tool has the advantages that part of space in the main casing is reserved for accommodating dust, so that the volume of the polishing tool is reduced, the deflection caused by the large volume of the dust suction container is avoided, and the operation flexibility is improved.
