Patent ID: 7900799

Claim:
A dispenser apparatus for dispensing a liquid from a bottle having a neck portion, the dispenser apparatus comprising: a housing formed with a flow conduit there through in fluid communication with the liquid within the bottle, the flow conduit having an inlet conduit, an outlet conduit and a substantially cylindrical cavity positioned between the inlet conduit and the outlet conduit; a flow wheel positioned in the cavity, the flow wheel having a central axis and a plurality of blade elements extending outwardly relative to the central axis; a flow sensor positioned adjacent to the flow wheel and the cavity for detecting movement of the plurality of blade elements of flow wheel; an electromagnetic valve positioned proximate to the outlet conduit, the electromagnetic valve having an actuation unit outside of the outlet conduit, a valve member inside the outlet conduit, and a spring member biased against the valve member within the outlet conduit, the valve member rotatable between a closed position and an open position upon the actuation of the actuation unit; a microprocessor operatively connected to the flow sensor, the microprocessor programmed for actuating the actuation unit between the closed position and the open position and for measuring the volume of liquid flowing through the flow conduit via the flow wheel; a motion sensor switch operatively connected to the microprocessor for forming an electrical connection with a battery and supplying power to the microprocessor for forming an electrical connecton with a battery and supplying power to the microprocessor upon the detection of movement of the bottle, wherein the motion sensor switch is positioned within the nozzle portion for detecting movement of the bottle, the motion sensor switch having a first contact plate, a second contact plate vertically spaced apart from the first contact plate, a contact ring disposed between the first contact plate and the second contact plate, and a ball bearing.
