Water Focusing Cleaning Head

摘要

A rug cleaning head for a traditional rug cleaning application machine is improved. The spray apparatus remains prior art. The vacuum components on the underside of the cleaning head are improved with a focusing diverter arm or a pair of arms forming a “V”. The arm or arms direct the wash water into a reduced size (about a one inch slot) vacuum inlet. The result is much more wash water is collected from the rug due to the combination of a higher speed (reduced size) vacuum inlet stream and the focusing diverter's urging all the wash water into the smaller vacuum inlet. An alternate embodiment uses separate spray/vacuum inlet assemblies on a star shaped hub.

主权项

1. A rotary carpet cleaning head comprising:
a plate shaped base having a top surface and a bottom surface; said plate shaped base having a connection for a powered hub which rotates the plate shaped base; a plurality of wash water spray nozzles attached to the plate shaped base which when in use spray wash water into a carpet to be cleaned; a first diverter arm attached to the bottom surface behind a first wash water spray nozzle so as to form an acute angel smaller than or equal to about 85° relative to a radius axis from a center of the plate shaped base through a vacuum inlet; said vacuum inlet cannot extend beyond the first diverter arm; said first diverter arm located between the center of the plate shaped base and the vacuum inlet and the acute angle measured inbound from the first diverter arm; said first diverter arm extending from the first wash water spray nozzle to the vacuum inlet; said first diverter arm having a height to rest on the carpet to be cleaned, wherein a support for a weight of a powered applicator machine is supported by the first diverter arm; and said vacuum inlet has an opening area of less than about one half a square inch.
