摘要： A power tool with a dust collection function has a motor, a dust collection fan, and a cover member. The dust collection fan is driven by the motor for collecting a dust. The cover member covers the dust collection fan. The cover member provides an air passage surrounding the dust collection fan in an circumferential direction of the dust collection fan. The cover member is configured and arranged to provide a lower pressure section and another section in the air passage when the dust collection fan rotates. The lower pressure section provides a lower static pressure than the another section. Accordingly, the power tool ensures highly efficiency for collecting a dust particle.
