Abstract:
1. A dental cleaning apparatus using liquid droplets, comprising: an appliance body ( a source of compressed gas ( a reservoir for liquid ( a liquid chamber separate from the nozzle assembly and one or more connecting lines between the reservoir for liquid and the liquid chamber; and one or more liquid connecting pathways between the liquid chamber and the nozzle assembly interior pathway or from the liquid chamber into the stream of gas in the nozzle assembly, wherein the one or more liquid connecting pathways are so configured and have an exit point in the nozzle assembly that gas moving through the nozzle assembly interior pathway draws liquid from the liquid reservoir into the liquid chamber and from there into the stream of gas, resulting in the creation of liquid droplets which then move out through the at least one nozzle exit orifice toward the dental regions to be cleaned, wherein the appliance body includes a base portion containing the liquid reservoir and the source of compressed gas and wherein the liquid chamber defines a sleeve including a wall portion and a central open portion, the wall portion having a plurality of longitudinal openings therethrough, wherein liquid is drawn from the liquid reservoir into the longitudinal openings by differential pressure created by a flow of gas through the central open portion of the sleeve.
