摘要： A cylindrical power brush for a vacuum cleaner includes two types of bristle tufts (70). One type (70 b ) of bristle tuft is short and stiff for contacting and agitating a carpeted surface. The other type (70 a ) of bristle tuft is longer and softer for contacting a hard surface. In addition to the differences in length and bristle stiffness, the tufts (70 b ) for the hard surface contain substantially fewer bristles, whereby catching and rolling of carpet edges is avoided. One embodiment alternates types of bristle tufts in a row of bristle tufts. Another embodiment employs multiple rows of bristle tufts arranged such that a point on a surface being cleaned is contacted alternately by the two types of bristle tuft. Winding up of thread and hair on the axle of the rotating brush is avoided by overlapping annular extensions (190, 188) on a support wheel (184) and a brush spindle (186). The brush support wheel is locked in place in the floor tool by a resilient locking tab integrally formed with one of the halves of the floor tool.
摘要翻译：用于真空吸尘器的圆柱形电刷包括两种类型的刷毛簇（70）。刷毛簇的一种类型（70b）短而坚硬，用于接触和搅拌地毯表面。刷毛簇的另一种类型（70a）较硬和较软，以使硬表面接触。除了长度和刷毛刚度的差异之外，用于硬表面的刷毛簇（70b）还包含基本上较少的刷毛，从而避免了地毯边缘的捕获和滚动。一个实施例在一排刷毛簇中交替刷毛簇的类型。另一个实施例采用多排刷毛簇，其布置成使得被清洁的表面上的点被两种刷毛簇交替地接触。通过在支撑轮（184）和刷轴（186）上重叠环形延伸部（190,188）来避免旋转刷的轴上的线和头发的旋转。刷支撑轮通过与地板工具的一半之一整体形成的弹性锁定片锁定在地板工具中的适当位置。

摘要： A hand-held vacuum cleaner (10) includes a housing (11) having first and second half housing elements (12, 14). The housing (11) has a handle (16) and a nozzle (20). A motor (24) is mounted within the housing (11) for driving a shaft (30). A fan (32) is mounted on the shaft for rotation therewith. A selectively separable bag assembly (40) is mounted on the housing (11). A working air channel (36) is formed within the housing (11) for communicating the nozzle (20) with the bag assembly (40). The air channel (36) terminates in a working air outlet chute (38) positioned within the bag assembly (40) at its open upper end. The air channel (36) directs the working air upwardly within the cleaner (10) from the outlet of the fan (36) to the outlet chute (38).

摘要： A wet-dry vacuum cleaner includes a liquid separator (52) having an end wall (54) facing air flow from an inlet chute (50). The end wall (54) is surrounded by a top shelf (60), lateral sidewalls (58) and a lower shelf (62) to define a pocket (64) within which moisture droplets entrained in the flow of air are encouraged to precipitate. Turbulence fences (68, 70, 72) within the pocket (64) induce eddies in the air flow to further induce moisture precipitation. The top shelf (60) forces swirling air from the inlet chute (50) to contact the top shelf (60) before entering the air inlet (66), thereby reducing the tendency for swirling air flow to carry moisture directly into the air inlet (66). An entry step (84) at the bottom of the air inlet (66) inhibits moisture precipitated on the top shelf (60) from passing into the air inlet (66). Additional ribs and/or turbulence fences (86, 88) may be disposed on an inner surface of the dust bowl housing (42).

摘要： A dust bowl (54) of a hand-held vacuum cleaner (42) is attached to a power unit (44) using top (72) and bottom (74) latches which are actuated by pushing a single actuator button (84). Both latches (72,74) are outside a sealed space through which air flows, and are thus not sources of air, soil or liquid leakage. A wishbone-shaped pusher (102) transmits mechanical actuation forces from the actuator button (84) for actuating the upper latch (72) to a spring bar (110) connected to a bottom latch cam (118). When the actuator button (84) is pushed, the spring bar (110) is correspondingly moved to release the bottom latch (74) in coordination with release of the top latch (72). A forward support member (52) of the power unit (44) cradles a portion of the dust bowl (54) to provide support and lateral stability between the elements. A tab (76) extends from the bottom of the dust bowl (54) to overlap a forward edge (78) of the forward support member (52) to provide further stability to the fit.

摘要： A vacuum cleaner (10) includes a telescoping handle (22) having a plurality of resilient pads (106, 116) for preventing vibration and motion of the handle (22) with respect to the remainder of the vacuum cleaner. All elements of the vacuum cleaner are mounted on a single frame (34). A power unit (12) includes two halves which are mounted on the frame (34) from opposite sides. A socket (26) at a lower end of the frame (34) receives the lower end (38) of a substantially rigid dust bowl (14). The upper end (30) of the dust bowl (14) includes a gasket (50) maintained in face-sealing contact with a lower surface (32) of the power unit (12). A latch assembly (123) in the frame (34) includes a locking dog (128) urged into locking entry in one of two openings (117, 119) in the telescoping handle shaft (22). A pair of ramp teeth (134) enter corresponding limit ramps (125, 127) when an attempt is made to extend the handle (22) beyond its normal extension. This prevents further extension but mating ramp surfaces (144, 148) permit retraction to one of the normal locking positions.
