Abstract
An oral irrigator has a base unit housing a motor and a pump, a removable reservoir defining a reservoir cavity configured to mechanically couple to a top surface of the base unit and fluidly couple the reservoir cavity to the pump, and a belt drive assembly connecting the motor to the pump. The belt drive assembly includes a drive pulley connected to an output shaft of the motor, a driven pulley spaced apart from the drive pulley and mechanically connected to a piston that drives the pump, and a continuous belt connecting the drive pulley to the driven pulley. A handle for the oral irrigator may include a housing defining a slot formed in an outer wall of the housing.
Claims16
A handle for an oral irrigator for directing a focused stream of fluid, the handle comprising:
- a housing having a first end and a second end, the housing comprising:
- a front housing half:
- a rear housing half comprising a convex outer wall;
- and
- a slot formed in the convex outer wall of the rear housing half, the slot comprising:
- two opposing walls spaced apart from each other;
- and
- a transverse wall at a terminal interior end of the opposing walls such that the convex outer wall of the housing is open to the slot at lateral sides of the two opposing walls and at a base end of the opposing walls opposite the transverse wall;
- a fluid tip coupled to the first end of the housing;
- wherein:
- the slot is positioned adjacent to a center of mass of the handle;
- the slot is configured to receive a portion of a reservoir wall of the oral irrigator;
- and
- the slot extends upwards and inwards towards the first end of the housing and towards an internal cavity of the handle defined by the housing, wherein an interior surface of the housing defines an angled wall extending towards a longitudinal axis of the housing, wherein the angled wall is defined by the transverse wall of the slot, and wherein the handle is configured to hang via the slot with the fluid tip positioned above the housing.

- a housing having a first end and a second end, the housing comprising:
- a front housing half:
- a rear housing half comprising a convex outer wall:
- and
- a slot formed in the convex outer wall of a rear portion of the rear housing half, wherein the convex outer wall is open to the slot, the slot comprising:
- two opposing walls spaced apart from each other;
- and
- a transverse wall at a terminal interior end of the opposing walls such that the convex outer wall of the housing is open to the slot at lateral sides of the two opposing walls and at a base end of the opposing walls opposite the transverse wall;
- wherein:
- the slot is positioned adjacent to a center of mass of the handle;
- the slot is configured to receive a portion of a reservoir wall of the oral irrigator;
- and
- the slot extends upwards and inwards in a direction towards the first end of the housing and towards an internal cavity of the handle defined by the housing, the slot defining an angled wall on an interior surface of the housing, the angled wall extending towards a longitudinal axis of the housing, and wherein the oral irrigator is configured to hang via the slot with a fluid tip positioned above the housing.
An oral irrigator for directing a focused stream of fluid, the oral irrigator comprising:
- a handle comprising:
