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.
Claims8
A method comprising:
- employing a varying magnetic field to move or reciprocate a liquid conducting tube of a liquid dispenser apparatus;
- and
- using one of a solenoid device or a voice coil actuator device to provide the varying magnetic field.
Apparatus comprising:
- a stepper motor having a hollow tube positioned therein and the motor and hollow tube being configured such that motor drives the hollow tube up and down in response to supply of a plurality of electrical pulses thereto;
- the hollow tube being constructed to inter-fit with a stem of a pump such that driving the hollow tube up and down creates a pumping action.
