摘要:
An air path for a vacuum cleaner, such as a stick type or broom type vacuum cleaner includes a first fan shell section having a first end at which is located a suction opening and a second end. A second fan shell section has a first end and a second end at which is located an outlet opening. An air outlet tube is located at the outlet opening of, and is of one piece with, the second fan shell section. The two fan shell sections are secured to each other in order to define a chamber between them. A suction fan is located in the chamber for drawing a suction at the suction opening and directing air through the air outlet tube.
