Abstract

A power tool, including: a housing, extending in a longitudinal direction; and a fan, a motor, and a circuit board that are received in the housing. The housing defines an air outlet, a first air inlet, and a second air inlet. The first air inlet is adjacent to the motor, and the second air inlet is adjacent to the circuit board; the first air inlet is disposed between the air outlet and the second air inlet. The power tool includes a first heat dissipation air path that flows through the motor and a second heat dissipation air path that flows through the circuit board. The motor includes an output shaft extending along the longitudinal direction. The output shaft is connected to the fan; the air outlet, the fan, the first air inlet, and the second air inlet are arranged sequentially in an axis direction of the output shaft.
