E-cigarette vaporizer cartridge filling device

A method for operating a vaporizer cartridge filling device, the method comprising the acts of:

• providing a frame supporting a fluid dispenser, a microcontroller that controls the fluid dispenser and a user interface, the fluid dispenser comprising a reservoir that drains to a tube, a valve that allows the fluid to flow through the fluid dispenser in one directions, a syringe comprising a plunger, the syringe coupled to the tube and to a motor that is coupled to a threaded rod, wherein the plunger moves as the motor rotates the threaded rod;
• calibrating a volume to be dispensed from the syringe by defining the volume by a lower limit of travel and an upper limit of travel of the plunger and running a program that sets at least one of the lower limit and the top limit using positional feedback to precisely control the volume;
• saving at least one of the lower limit and the upper limit defining the volume;
• loading the fluid into the reservoir;
• setting a speed to dispense the volume of fluid from the syringe;
• wherein moving the plunger from the lower limit to the upper limit draws the liquid from the reservoir to the syringe and moving the plunger back to the lower limit dispenses the fluid from the syringe;
• activating at least one of the draw and the dispensation of the fluid by operating a switch that initiates movement of the plunger;
• and
• loading a cleaning solution into the reservoir and allowing the fluid dispenser to continuously purge the system with the cleaning solution until the reservoir is empty or for a predetermined time period.
