Cordless water flosser

Abstract

A water flosser is provided that may include a body, a reservoir, a cap coupled to the body and a tip extending through an opening in the cap. The water flosser may include a latch assembly that selectively retains the tip to the body. In one embodiment, the cap, the tip and the latch assembly are all rotatable as a unit about a defined axis relative to the body. An ejector button may be provided to actuate the latch assembly. In one embodiment, the ejector button extends through an upper surface of the cap. Actuation of the latch assembly may include displacement of the ejector button in a direction that is parallel with a rotational axis of the tip. In some embodiments, the reservoir of a water flosser includes a tapering volumetric section that concentrates a volume of fluid about an inlet of a tube coupled with a pump.
