a blower

Abstract

The invention discloses a blower comprising a shell, an impeller and a motor. The shell is composed of a front shell and a rear shell. The impeller comprises a central disc and blades fixed on the central disc. A plurality of grooves are formed in the central disc by stamping. The central disc is provided with a plurality of square holes. The rear shell comprises a base and an impeller accommodating part. One side of the impeller accommodating part, far away from the front shell, is provided with a projecting motor accommodating part for accommodating the motor and an electric parts accommodating part for mounting electric parts. The electric parts accommodating part is communicated with an inner cavity of the motor accommodating part. The inner wall of the rear shell is peripherally provided with a plurality of third threaded holes for connecting the motor. One side of the motor accommodating part, far away from the front shell, is provided with square openings for motor cooling and an extending guard corresponding to the square openings. An exhaust hole is formed between the guard and the motor accommodating part. The blower is fast and convenient to mount and fine in radiating effect.

Description

technical field [0001] The invention relates to a blower. Background technique [0002] In the existing blower, the motor is generally installed in the installation box at the rear of the casing, the installation box takes up a large space, and it is troublesome to assemble, and the installation process is cumbersome. In addition, for the blower with this structure, since the center of gravity of the blower is biased towards the rear where the motor is installed, the blower will cause a lot of vibration during operation, and the blower is prone to rollover. [0003] In addition, the motor of the blower is generally installed in the mounting frame behind the casing, that is, the casing and the mounting frame are separated. This structure takes up a lot of space, and the installation of the motor is troublesome. It is necessary to connect the mounting frame with the rear shell of the housing, so the operation process is cumbersome and cumbersome. In addition, there are no coo...

[0002] In the existing blower, the motor is generally installed in the installation box behind the casing, the installation box takes up a lot of space, and it is troublesome to assemble, and the installation process is cumbersome

In addition, for the blower with this structure, since the center of gravity of the blower is biased towards the rear where the motor is installed, the blower will bring a lot of vibration during operation, and the blower is prone to rollover

[0003] In addition, the motor of the blower is generally installed in the mounting frame behind the casing, that is, the casing and the mounting frame are separated. This structure takes up a lot of space, and the installation of the motor is troublesome. It is necessary to connect the mounting frame with the rear shell of the housing, so the operation process is cumbersome and cumbersome. In addition, there are no cooling holes on the mounting frame, or although the cooling holes are set, the arrangement of the cooling holes is not very reasonable, so the heat dissipation effect of the motor Not good, and dust and other sundries are easy to fall into the mounting frame from the cooling hole, which will affect the normal use of the motor
