VACUUM POWERED SURFACE CLEANING APPARATUS

摘要

A vacuum powered surface cleaning apparatus which is capable of cleaning an adjacent surface to remove debris without external leaking, dripping or misting. The vacuum powered surface cleaning apparatus includes an eductor assembly to create a vacuum within the device to naturally induce a flow of cleaning fluid which is imparted onto the adjacent surface to be cleaned. The expended cleaning fluid and debris are expelled from the apparatus through the eductor to external atmosphere or to an external waste or recycling container. Removal of the adjacent surface opens the internal chamber which causes a loss of partial vacuum which ceases flow of cleaning fluid, thereby eliminating the possibility of external dripping or misting.

主权项

1. A vacuum powered surface cleaning apparatus comprising:
an enclosed partial vacuum chamber comprising:
a partially enclosed chamber; andan adjacent surface; and an eductor assembly comprising:
an air nozzle; andan eductor throat; andan eductor outlet; a connecting duct which connects the eductor assembly to the enclosed partial vacuum chamber; a compressed air supply; a cleaning fluid supply comprising;
an external cleaning fluid source; anda cleaning fluid flow channel;wherein the compressed air supply passes through the air nozzle and is converted from high static pressure to low static pressure and high dynamic pressure, and the ejected low static pressure air stream enters the eductor throat inducing a low static pressure within the connecting duct and enclosed partial vacuum chamber which induces a flow of cleaning fluid from the cleaning fluid source and through the cleaning fluid flow channel and imparts the flow of cleaning fluid onto the adjacent surface to be cleaned, and expended cleaning fluid together with dislodged debris are expelled from the partial vacuum chamber through the connecting duct and through the eductor and through the eductor outlet.
