The invention discloses a motor box structure for lowering the noise of a motor. The motor box structure comprises a motor box body with one end being opened and a motor box cover connected with the opened end of the motor box body, wherein a plurality of air inlets are formed on a convex platform that protrudes in the center of the motor box cover, a sunk part that is sunk towards the direction of a fan-motor unit arranged in the motor box body is formed in the center of the convex platform, and air inlets are formed on the sunk part. For the motor box structure for lowering the noise of the motor, the hemispheric sunk part that is sunk towards the direction of a fan-motor unit is formed in the center of the convex platform arranged on the motor box cover, and the direction is consistent with the flowing direction of inlet air of the motor, so as to increase the air inlet volume to the maximum limit and effectively lower the noise at the air inlets of the motor caused by the flow of the air. Radial equal-interval partitions are arranged from the center of the sunk part to the outside, so as to play a role in guiding the air entering the motor, so that the air can not enter the motor disorderly, thereby lowering the noise at the air inlets of the motor.
Description
technical field [0001] The invention belongs to the field of electrical equipment for vacuum cleaners, and in particular relates to a motor box structure in which a recess is formed in the center of a boss on a motor box cover, and radial partitions are arranged outward from the center of the recess to reduce motor noise. Background technique [0002] Vacuum suction is a cleaning and sanitary appliance used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body of the vacuum cleaner. The suction pipeline includes a suction head, a suction pipe and a suction hose. The head has a suction port opening downwards and communicates with the air inlet of the fan inside the vacuum cleaner body through a dust suction pipe and a dust suction hose. [0003] When the vacuum cleaner is runnin...
