    摘要： An airflow indicator for a vacuum cleaner includes a housing, a wheel chamber defined in the housing, and a rotatable wheel mounted in the wheel chamber. The wheel has protrusions which cause the wheel to rotate due to inlet air flow. The wheel further has markings which gradually increase in size along an outside perimeter of the wheel. The markings indicate movement of the wheel. An air inlet is formed adjacent a first end of the housing. An air passageway is formed within the housing adjacent the rotatable wheel and the air inlet. The air passageway is curved to facilitate air flow along the protrusions of the wheel. A valve is mounted within the housing adjacent the air passageway. The valve has a cross slit which opens in response to a change in vacuum pressure. An air outlet is formed in the housing. A window portion partially encloses the wheel within the wheel chamber. The window allows viewing of the wheel from outside of the housing.

    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.

    摘要： An upright vacuum cleaner (A) includes an upright housing section (B) and a nozzle section (C). A cyclonic airflow dirt and dust separating chamber (54) is defined in said upright housing section. A suction source (E) pulls air and entrained dirt, dust, and other contaminants through a main suction opening (26) formed in the underside (24) of the nozzle and into the cyclonic airflow chamber (54). The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container (52) that defines the lower portion of the chamber (54). A main filter element (11) filters residual contaminants from the suction airstream between the chamber and the suction source. The main filter element is preferably made from high-density polyethylene porous filter media. A final filter assembly (F) filters the section airstream discharged by the suction source to ensure that the air discharged into the atmosphere is contaminant free, including those contaminants introduced into the airstream by the suction source itself.

    摘要： A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters said main suction opening, passes through said cyclonic chamber, and passes to an outlet of said suction source. A substantial portion of particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber. A main filter assembly, preferably including filter medium comprising polytetrafluoroethylene (PTFE), is located in the cyclonic chamber so that a suction airstream moving from the main suction opening to the inlet of said suction source by way of the cyclonic airflow chamber passes through the filter medium thereof after said airstream moves in a cyclonic fashion within the cyclonic airflow chamber to remove residual particulates from the suction airstream before it leaves the cyclonic chamber. A HEPA filter can be provided to filter the suction airstream exhausted through the outlet of the suction source prior to the airstream being discharged from the vacuum.
