Abstract
The utility model involves a high-efficiency electric fan fixed impeller for vacuum cleaners, which includes an intermediate plate with a center hole, multiple arc-shaped upper blades and lower blades which are distributed in spiral-shape on the upper surface and the lower surface in a circumferential direction. The upper surface is installed with the inscribed circle cavity which is connected with the extending end of the inside of blades. The described two adjacent impellers form an air flue, which becomes narrow gradually and is narrow in the front and wide in the back from outboard to the inscribed circle cavity. A common arc is arranged between the expanding end of the upper blade and the inscribed circle cavity. The fixed impeller makes the air flue between adjacent blades narrow in the front and wide in the back so as to form a certain pressure in the air flue and to form negative pressure. The negative pressure reduces the backflow and eddy of air current. When the flow velocity of the air current reaches a certain critical point, the flow and the values of negative pressure are maximum, and the output power of the fan is improved so as to make the air flue more fluid.
