Problems solved by technology

The motors of cutting tools usually include inner rotor motors and outer rotor motors. At present, conventional cutting tools often use inner rotor motors, but compared with inner rotor motors, outer rotor motors have the advantages of small size and large torque, but there are The problem of high heat dissipation requirements, so the current conventional cutting tools cannot meet the high heat dissipation requirements of external rotor motors in terms of heat dissipation

Abstract

The invention relates to an electric tool, in particular to a cutting tool. The electric tool comprises a functional part used for achieving tool functions, a motor used for driving the functional part to operate, a fan arranged on one side of the motor and a motor shell used for containing the motor, wherein the motor is an external rotor motor, the electric tool further comprises an airflow guiding device arranged on the outer side of the fan in a surrounding mode, an air outlet is formed in the airflow guiding device, the airflow guiding device is provided with an arc-shaped air guiding side wall, the air guiding side wall is provided with a first end close to one side of the air outlet and a second end opposite to the first end, and the linear distance from the air guiding side wall to the central axis of the fan is gradually reduced from the first end to the second end.

Description

technical field [0001] The invention relates to an electric tool, especially a cutting tool. Background technique [0002] The cutting tool is used to realize the cutting function, and has the characteristics of safety, reliability and high work efficiency. The cutting tool is mainly composed of a motor, a gearbox, a shield assembly, a base plate, and an electric control system. The motors of cutting tools usually include inner rotor motors and outer rotor motors. At present, conventional cutting tools often use inner rotor motors, but compared with inner rotor motors, outer rotor motors have the advantages of small size and large torque, but there are The problem of high heat dissipation requirements, so the current conventional cutting tools cannot meet the high heat dissipation requirements of external rotor motors in terms of heat dissipation. Contents of the invention [0003] The purpose of the present invention is to provide an electric tool that can adopt an exte...
