AI Technical Summary
Technical Problem
Wall sanders generate a lot of dust and powder during operation, which shortens the lifespan of the motor.
Method used
It adopts a maze dustproof structure, which forms a maze effect through the cooperation of the back cover and the dustproof plate to prevent dust and powder from entering the inside of the casing.
Benefits of technology
This effectively reduces the amount of dust and particulate matter inside the casing, thus extending the lifespan of the motor.

Abstract
The utility model discloses a labyrinth dustproof structure of wall polisher, including casing, back cover and dustproof board, the casing is used for accommodating motor, the output shaft of motor has central axis, dustproof board, back cover assembly to casing, back cover has the end face of setting up air intake, and the end face and dustproof board are perpendicular to central axis, and the end face of back cover and dustproof board respectively have the first cooperation structure and the second cooperation structure along central axis extension and opposite setting, and the first cooperation structure and the second cooperation structure form the labyrinth dustproof structure each other interlaced. The first cooperation structure and the second cooperation structure form the labyrinth structure of the arch character, and the dust, dust and the like of outside are blocked by the labyrinth dustproof structure formed by the first cooperation structure and the second cooperation structure when entering along with gas, thereby effectively reduce the dust, dust amount of entering in the casing.
