Abstract: Automatic electric actuation of the pump of a liquid dispenser apparatus is provided by a stepper motor having a threaded hollow liquid-conducting tube positioned therein and configured such that motor drives the hollow tube up and down in response to supply of a plurality of electrical pulses thereto. A lower end of the hollow tube is constructed to inter-fit with a stem of the pump such that driving the hollow tube up and down creates a pumping action.
Abstract: Automatic electric actuation of the pumping mechanism of a liquid dispenser apparatus is provided by configuring a hollow tube to cooperate with an electromagnetically driven actuator and further configuring the hollow tube to inter-fit with a stem of a liquid dispensing pump. Actuation of the actuator may, for example, drive the pump stem downwardly to cause a pumping action. Suitable actuators include, for example, solenoids, voice coil actuators and stepping motors.
Abstract: A liquid dispenser apparatus having a back plate, a housing, and a liquid dispenser unit, the housing and backplate being constructed to attach to one another, the housing and liquid dispenser unit being constructed such that the liquid dispenser unit is removably installable into the housing and pivotally mounted with respect thereto such that the dispenser unit can be pivoted to a selected acute filling angle with respect to the housing.
