An oral irrigator handle including a housing and a first fitting, the first fitting including a first fitting inlet in fluid communication with a handle inlet in fluid communication with a fluid source and a first fitting outlet in fluid communication with the first fitting inlet. The handle includes a seal positioned around the first fitting and between the first fitting inlet and the first fitting outlet. A second fitting includes a second fitting inlet in fluid communication with the first fitting outlet and a second fitting outlet in fluid communication with the second fitting inlet. A bottom portion of the second fitting seats on a portion of the first fitting so that the seal engages an interior surface of the second fitting, a flow passage is coupled to the second fitting and in fluid communication with the second fitting outlet.

The present disclosure relates generally to oral health products, such as electric toothbrushes. In one example, the electric toothbrush includes a housing, an output shaft positioned within and extending out of the housing, a magnetic assembly positioned within the housing and configured to impart an oscillation motion to the output shaft, and a spring positioned within the housing. The spring includes a first end non-rotatably coupled to the housing and a second end non-rotatably coupled to the output shaft, such that the spring twists as the magnetic assembly oscillates the output shaft to amplify the oscillation motion of the output shaft generated by the magnetic assembly.

Tip holder for oral cleansing device

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.

Toothbrush handle

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.

Tip ejection assembly for an oral irrigator

An oral irrigator handle has a handle housing with a swivel assembly for connection to a hose further connected to a fluid source. A tip for directing a focused stream of fluid is releasably connected to a first end of the handle. The swivel assembly is received within the housing and fluidly coupled to tip. The hose is connected to the swivel assembly and fluidly coupled to the tip via the swivel assembly. The swivel assembly prevents translation of rotational movement of the handle or the hose to the other.

Swivel assembly for oral irrigator handle

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.

Oral irrigator with slide pause switch

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.
