AUTOMATIC LIQUID DISPENSER

摘要

A free-standing or wall-mounted dispenser and system for automatically dispensing liquid, includes a base, which may be shaped so that the dispenser remains free of dispensed liquid, and may include a removable tray to catch accidentally or residually dispensed liquid. The dispenser generates an infrared signal in the proximity of the dispenser's spigot. A user's hand, or other object, intersects the infrared signal and causes the unit to dispense liquid. The dispenser accepts a DC power source, and includes an on-off switch, which can be switched off for refilling, moving or cleaning the dispenser, and prolonging battery life. A disposable liquid cartridge in the form of a bag or bottle with a valve can be incorporated into the system, together with a master switch disabling the dispenser until an acceptable keyed cartridge is properly inserted.
