发明名称 Auxiliary vacuum device for a central vacuum cleaning system
摘要 An auxiliary vacuum device for a central vacuum cleaning system is location specific and comprises housing mountable externally on an inlet of a mounting plate of the system, a dedicated flexible concertina hose is provided on the device and a cleaning tool mounting probe is registrable with a docking station. When the probe is removed from the docking station, a lever may be moved in first and second directions to selectively activate and deactivate the motor of the central vacuum cleaning system and the device. When the probe is parked in the docking station the probe moves the lever in one of the directions and holds the lever in a deactivated configuration, thus deactivating the motor and the device and preventing activation thereof.
