Docking and charging station and filling operation for a hand-held oral cleaning device

A method of using a docking and charging station having a pump, a reservoir having first and second male ports, a cradle, and a docking refilling alignment mechanism for automatically filling a chamber of a hand-held fluid droplet appliance suitable for dental cleaning, comprising the steps of:

• placing the hand-held fluid droplet appliance into the cradle of the docking and charging station;
• aligning the first and second male ports of the reservoir of the docking and charging station with respective first and second female ports on a door of the chamber of the hand-held fluid droplet appliance;
• pressing on the cradle to engage the docking refilling alignment mechanism such that the male ports of the reservoir of the docking and charging station engage the respective female ports;
• pumping liquid from the reservoir on the docking and charging station through the conjoined male and female inlet ports into the chamber of the hand-held fluid droplet appliance;
• and
• evacuating air and any excess liquid from the chamber of the hand-held fluid droplet appliance to the reservoir through the conjoined male and female liquid and air exit interface ports.
