A power tool includes a main body and a battery pack. The main body includes a housing and a motor, a switch assembly, and an electronic control device. The electronic control device is electrically connected to the switch assembly and the motor. The electronic control device includes an electronic control assembly, a mounting base, and a connecting assembly. The electronic control assembly includes a power circuit board. The power circuit board is provided with an opening. The connecting assembly conductively connects the battery pack to the electronic control assembly, connects to the mounting base via the opening, and mates with the mounting base to form a mounting space in which the electronic control assembly is mounted.

A power tool includes a housing, a tool attachment, an output shaft, an electric motor, and an airflow channel. The housing includes an air inlet and an air outlet, and an airflow channel is formed between the air inlet and the air outlet. The electric motor includes an electric motor shaft, a stator and a rotor. The power tool further includes a thermal conduction member disposed between the rotor and the stator and configured to transfer heat between the rotor and the stator into the airflow channel. Further disclosed is an angle grinder. The power tool has good heat dissipation performance.

Angle grinder, air blower, and power tool

A hand-held power tool includes a housing, a motor having a motor shaft, and a fan mounted onto the motor shaft and driven by the motor. The fan has a plurality of large and small fan blades arranged in a staggered form on a surface of the fan. Such arrangement of the fan blades effectively improve the heat dissipation efficiency of the power tool.
