Abstract:
Apparatus for dispensing a measured quantity of fluid, comprising:a) an object sensor; b) a container carrying a supply of fluid; c) a dispense mechanism coupled to said container to control an amount of fluid to be dispensed; and d) a pump actuator mechanism coupled to said object sensor, wherein detection of an object by said object sensor cycles said pump actuator mechanism to engage said dispense mechanism which dispenses a measured quantity of fluid and wherein said pump actuator mechanism converts rotational motion to linear motion to cycle said dispense mechanism, wherein said pump actuator mechanism comprises a motor having a rotatable shaft, a differential gear assembly driven by said rotatable shaft, and an actuator gear driven by said differential gear assembly to cycle said pump actuator mechanism, and wherein said differential gear assembly includes at least one gear having a hub which slidably receives said actuator gear.
