Abstract: A chassis of an oral cleansing device is provided. The oral cleansing device may include a first chassis half including a first threaded portion, a second chassis half including a second threaded portion, and a nut threaded onto the first threaded portion and the second threaded portion to at least partially secure the first chassis half to the second chassis half. The threaded portions may be defined on respective ends of the first chassis half and the second chassis half. The nut may engage chamfered edges of the first chassis half and the second chassis half. Engagement of the nut with the first chamfered edge and the second chamfered edge may produce a radial compressive force on the chassis halves. The first chassis half and the second chassis half may at least partially define a chassis that is positioned within a handle of the oral cleansing device.

Abstract: An oral cleansing device including a base and a tip holder configured to hold a tip for the oral cleansing device, such as a brush head, a jet tip, or a combination tip. The tip holder may be removably coupled to the base.

Abstract: An oral irrigator including a base, a reservoir supported by the base, a tip coupled to the base and the reservoir, and multiple control actuators. A first control actuator is configured to selectively power the oral irrigator. Second, third, and fourth control actuators are configured to vary the fluid pressure of the oral irrigator.

Abstract: An oral irrigator including a handle housing defining a cavity, a tip removably connected to the handle housing, and a tip release assembly connected to the handle housing. The tip release assembly includes a tip eject button slidably connected to the handle housing and movable between a first position and a second position and a latch connected to the handle housing and positioned within the cavity. Movement of the tip eject button from the first position to the second position moves the latch laterally across the cavity from an engage position to a disengage position.

Abstract: An oral irrigator including a handle through which fluid flows to a tip. Fluid flows to the tip during irrigate mode, and fluid flow may be interrupted by selecting a pause mode. The handle includes a mechanically controlled actuator for selecting the pause mode. The actuator may include a rack gear operably connected to a pinion gear formed on a valve spool inside the handle. The valve spool may include a ball that blocks fluid flow to the tip during pause mode but not during irrigate mode.

Abstract: An apparatus for oral hygiene is disclosed herein. The apparatus includes a base unit containing a reservoir, an oral irrigation handle, a sonic toothbrush, and an accessory container. The apparatus may include a pump, which may move pressurized water from a reservoir to a tip in fluid communication with the pump. The apparatus contains a drive mechanism in a gear housing that is continually drained by one or more apertures in the base. The base may include a plurality of footings that elevate the base unit above a surface supporting the base unit. The oral irrigation handle includes a pause switch that translates longitude motion into rotational motion to close a valve.
