摘要:
A vacuum cleaner comprising a cylindrical main body (215) incorporating a dust collection chamber (216) and a blower (218) and having a suction part (219) for sucking dust disposed ahead of the main body. A cylindrical handle arm (227) is formed to rotate on the outer circumference (225) of the main body around an axis of rotation (226) which coincides with the longitudinal axis of the main body.
摘要:
Rechargeable vacuum cleaner which allows the cleaner main body (401), accomodating the battery (403), to be connected to the charger (407), for charging the battery (403), only when the main body swithc (417)is cutted off mechanically. The switch (417) is locted in the cleaner main body (401) and is connected between the battery (403) and a blower (404). A manipulation unit (402a,402b,402c) for this switch (407) is also located in the cleaner main body and has an engaging portion (402c) to be engaged with a mating portion (412) provided on the charger (407), for setting the cleaner main body (401) on the charger (407). This engaging portion (402c) moves corresponding to the operation of the manipulation unit so that the engaging portion (402c) cannot be engaged with the mating portion (412) in the turned-on state of the switch (417).

A jet port (358) for jetting supply air from an electric blower built in a cleaner body into a suction opening (355) of a suction port body (350) is provided, and a closer such as a rib (360) made of an elastic material for closing the gap between the bottom of the suction port body (350) and the face to be cleaned is provided to an edge part (359B), out of an edge part (359A) near the portion where the jet port (358) is formed and the edge part (359B) both formed at the suction opening (355) so as to prevent leakage of jetted air from the jet port (358) to the outside.
摘要:
A wet/dry utility vacuum with a canister, a powerhead assembly with a fan, a shut-off device that prevents the fan from drawing liquids into the fan inlet when a volume of the liquid in the canister exceeds a predetermined volume. The powerhead assembly includes a controller that permits the utility vacuum to be operated in a desired power mode so that the user may employ either an AC power source or a DC power source, such as a battery pack, for example. In some applications, the battery pack may be interchangeable with the battery packs of various cordless tools, including drill/drivers and saws. A tool set and a method for operating a battery-powered tool set are also provided.

A fluid recirculating cleaning device (30) includes an exhaust port (52) defining an exhaust port longitudinal axis, a fluid source end and an exhaust end defining a first cross-sectional area. A suction port (54) includes a suction port longitudinal axis, a fluid exit end and a fluid entrance end defining a second cross-sectional area greater than the first cross-sectional area. The suction port (54) includes a second outer surface that extends from the entrance end toward the fluid exit end. A vacuum blower motor (18) sucks fluid in through the suction port (54) to create fluid flow away from the suction port (54) and toward the exhaust port exhaust end. The exhaust port exhaust end is recessed from the suction port fluid entrance end and the two ports (52, 54) are located with respect to one another so that fluid flow from the exhaust port (52) will be effectively drawn into the suction port (54).

A convertible blower port (18) for a vacuum cleaner (10) includes a cylindrical port wall (36) carried by a portion of a vacuum cleaner. The port wall (36) has a first end facing inwardly toward the vacuum cleaner and a second end opposite the first end. The port wall (36) defines a blower passage in communication with the plenum of the vacuum cleaner. A blower port outlet (40) is provided on the second end (39) of the port wall (36). A removable cap (20) closes off the blower port outlet (40) and has an exterior surface for gripping the cap and has a hub (60) configured to fill the blower passage. The hub (60) has a substantially smooth inner end face (62) that is positioned generally across the first end of the port wall and faces the plenum of the vacuum cleaner.
摘要:
An electric cleaning device circulates exhaust air from an electric blower (6) to a floor intake tool (54). The exhaust air passes through an exhaust guide (100, 105), formed as one element, in a main cleaning device unit (1) from the electric blower through a hose (24) to the floor intake tool (54). In one embodiment the exhaust guide is a resilient unitary resin part with sufficient resilience to permit compression for installation. The springback of the exhaust guide seals the exhaust path against leakage.
摘要:
A hand-held blower and adjustable blower nozzle attachment is disclosed for providing a variable rate air flow discharge from the nozzle attachment. The blower includes a housing having a handle, a discharge portion and a motor with an operatively connected impeller within a chamber connected to the discharge portion. A tubular body is attached to the discharge portion at one end and a blower nozzle attachment at a second end. The blower nozzle attachment includes at least one constrictor flap provided within the nozzle attachment body to change the air flow rate between a low air velocity rate in a first position and a higher air velocity rate in at least one second position. The adjustable blower nozzle attachment is provided with at least one aperture corresponding to the at least one constrictor flap for adjustment of the flap between the first and the at least one second position. A control is rotatably mounted to the nozzle body and includes a member mounted within the nozzle body to return the at least one constrictor flap from the at least one second position to the first position. Alternatively, the control may be slidably mounted to the nozzle attachment body. A member is pivotally connected to both the control and the at least one constrictor flap to move the at least one constrictor flap between the first and the at least one second position.
