Abstract

An electric tool grinding machine includes an electric motor, an airflow generating member, and a casing. The casing includes a hollow shell, a motor housing located in the hollow shell, two partitioning plates located between a side wall of the motor housing and the hollow shell, at least one air outlet facing the airflow generating member, a first air inlet formed on the hollow shell, and at least one second air inlet formed on the hollow shell and spaced apart from the first air inlet. When the airflow generating member is activated, the first air inlet generates a pressure difference in the hollow shell near an air inlet portion of the motor housing to cause air to be drawn into the second air inlet.
