    Abstract: A vacuum cleaner having a reduced velocity chamber with a high velocity air inlet, an electric motor, a rotary mechanism driven by the motor for creating a vacuum in the chamber, an outlet for exhausting air from the chamber, which air flows in a selected path from the air inlet, through the chamber and out the air exhaust outlet and a disposable porous sheet filter layer in the chamber for removing large solid particles from the air. The vacuum cleaner also has an improved filter, wherein the improved filter includes a layer of material to remove very fine air particles and a layer of material to remove odors from the air.

    Abstract: A self-aligning bearing structure for vacuum cleaner brushes and the like includes a plastic sleeve and a metal bearing element. The sleeve is initially formed with a flared end, allowing the bearing element to be inserted to provide a subassembly. The subassembly is then pressed axially into a cylindrical bore in the vacuum cleaner brush body. During such insertion, the flared end is deflected inwardly to produce a spherical socket which mates with a spherical periphery on the bearing element. Relative rotation between the sleeve and bearing element is prevented by a plurality of peripherally spaced teardrop-shaped projections formed on the sleeve which fit into teardrop-shaped recesses on the bearing element. The recesses are sufficiently closely spaced and are shaped in cooperation with the projections so that the recesses and projections automatically interfit upon assembly, and can therefore be assembled by automated equipment which does not require special orientation means. The interfitting projections and recesses prevent relative rotation between the sleeve and bearing element without requiring close tolerances in the manufacture of the components of the bearing.

    Abstract translation: 用于真空吸尘器刷子的自调心轴承结构等包括塑料套和金属轴承元件。 套筒最初形成有扩口端,允许轴承元件插入以提供子组件。 然后将该组件被轴向压入真空吸尘器刷体中的圆柱形孔中。 在这种插入过程中,喇叭形的端部向内偏转以产生与轴承元件上的球形周边配合的球形插座。 套筒和轴承元件之间的相对旋转被形成在套筒上的多个外围间隔开的泪珠形突起所防止,该泪珠装配在轴承元件上的泪珠状凹陷中。 这些凹槽足够紧密地间隔开并且与突起协调地成形,使得凹部和突起在组装时自动相互配合,并且因此可以由不需要特殊取向装置的自动化设备组装。 相互配合的突起和凹槽防止套筒和轴承元件之间的相对旋转,而不需要制造轴承部件的紧密公差。

    Abstract: A portable air cleaner designed to remove particles and unwanted gases from a room to provide for a healthier and cleaner environment. The portable air cleaner includes a high air volume circulating design and operates quietly and efficiently. The air exhaust of the air cleaner includes a plurality of arcuate vanes radiating outwardly from the interior of the air cleaner. The vanes are disposed in the air exhaust to reduce pressure drop and to minimize operation noise.

    Abstract: An air filtering and freshening device comprising a filter element within the intake of the device housing, a motorized fan mounted within the device housing which draws contaminated air into the device, and forces air out of the device through an outlet having separate exhaust and scent discharge passages. The exhaust passage including a plurality of arcuate vanes radiating outwardly from the interior of the device, and being disposed across the exhaust passage to promote efficient operation by reducing the pressure drop through the passage and minimizing operational noise. The scent discharge passage includes a scent element producing a freshening scent. The scent element is removably positioned adjacent the scent discharge passage, which carries high velocity, high pressure filtered air from the motorized fan, picks up the concentrated freshening scent, and discharges in an effective and efficient manner, a continuous stream of freshening scent.
