Technical Field
The utility model relates to a motor impeller cover structure and motor thereof.
Background
In general, a vacuum cleaner employs a motor having an impeller, the impeller is mounted on a shaft of the motor and is located in an impeller housing, and when the shaft of the motor rotates, the impeller is driven to rotate, so that external air is sucked in from a suction port of the impeller housing. The air sucked is sent to the outside of the impeller along with the blades of the impeller, flows into the space between the impeller and the impeller cover and is then conveyed to the rear end of the motor, and the traditional impeller cover structure can collide with the inner wall of the impeller cover to generate turbulence after the air enters the impeller cover at a high speed, so that the air suction efficiency is influenced.
