摘要:
A continuous flow recycling surface cleaning device includes a cleaning tool head incorporating a nozzle arrangement to enhance surface cleaning and drying. The head includes a shell that engages a surface being cleaned to form an enclosed chamber. A partition divides the chamber into intake and evacuation compartments. A row of nozzles is mounted to the shell to spray liquid cleaning solution into the intake compartment. Air enters the receiving sector through slots near the nozzles and between a forward portion of the shell and the floor, and is drawn beyond the partition into the evacuation compartment by a vacuum source. Each of the nozzles generates a sheet-like, fan-shaped spray pattern. The nozzles are arranged to form adjacent spray patterns that overlap one another longitudinally (lengthwise of the elongate shell) but are separated from one another to avoid interference between adjacent spray patterns. In one particularly advantageous arrangement, the nozzles are angularly offset from the lengthwise direction to form parallel spray patterns that define air passages between them. The shell, particularly along and adjacent the surface being cleaned, is configured to promote air flow into the intake compartment while resisting air passage into the evacuation compartment.
