Liquid extraction cleaning device

摘要

A liquid extraction cleaning device comprises a vacuum pump, a liquid pump, a cleaning solution tank, a recovery tank, first and second spray nozzles, a spray selection switch, a vacuum inlet port, an agitator assembly, and a handle. The spray selection switch controls whether liquid is expelled from the second spray nozzle when liquid is expelled from the first spray nozzle. The agitator assembly comprises first and second agitators. The first agitator is configured to rotate. The second agitator is configured to reciprocate. The handle is pivotally connected to the rest of the liquid extraction cleaning device and is lockable in several pivotal orientations. The handle can also be pivoted forward from a rearwardly extending direction to an extent that it extends forward horizontally.

主权项

1. A liquid extraction cleaning device comprising:
a main unit comprising a vacuum pump, a liquid pump, an agitator assembly, and a spray nozzle, the agitator assembly comprising an agitator, the spray nozzle being operatively connected to the liquid pump in a manner such that the liquid pump is capable of forcing cleaning liquid out of the spray nozzle; a cleaning solution tank, the cleaning solution tank being configured and adapted to store a cleaning liquid, the cleaning solution tank being operatively connected to the liquid pump in a manner such that the liquid pump can draw cleaning liquid from the cleaning solution tank; a recovery tank, the recovery tank being configured and adapted to store soiled cleaning liquid extracted from a floor, the recovery tank being operatively connected to the vacuum pump in a manner such that the vacuum pump can draw air from the recovery tank; a vacuum inlet port, the vacuum inlet port being operatively connected to the recovery tank and the vacuum pump in a manner such that the vacuum pump is capable of drawing fluid through the vacuum inlet port and into the recovery tank, the agitator being configured and adapted to move relative to the inlet port; and an adjustable handle, the handle being elongate in a lengthwise direction and pivotally connected to the main unit and comprising a locking mechanism and a release member, the locking mechanism being configured and adapted to lock the handle in each of a plurality of pivotal orientations relative to the main unit, the release member being configured and adapted to release the locking mechanism in a manner allowing the handle to pivot relative to the main unit, the locking mechanism comprising an internal linking member that is movable parallel to the lengthwise direction of the handle and that connects the release member to internal locking pins that cooperate with notched members that are fixed relative to the main unit.
