In one embodiment, an oral irrigator includes a reservoir, a base configured to support the reservoir, and a button assembly coupled to the base. The button assembly may include a button, a spring coupled to the button, and a seal coupled to the spring. The button may be movable between an original position and an actuation position. The spring may be configured to deform in response to a user input force moving the button from the original position to the actuation position, and to resiliently return the button to the original position in response to cessation of the user input force on the button. The seal may inhibit fluid from entering through the spring into the base.

A toothbrush tip includes a brush head, a plurality of bristle tufts extending from the brush head, a water jet nozzle extending from the brush head, and a cover panel arranged on a rear of the toothbrush tip opposite the bristle tufts.

The present disclosure includes embodiments directed to an oral cleansing device. The device may include a handle housing and a hose connector. The handle housing may include an end defining an aperture and the hose connector may be releasably coupled to the end. The hose connector may include a hose fluidly coupled to a reservoir and a body defining an inlet and an outlet. The hose may be coupled to the body and be in fluid communication with the inlet. The hose connector may include a collar coupled to the body and positioned around the hose at the inlet. In a first configuration, the outlet of the body may be positioned within the aperture of the handle housing and in a second configuration the outlet of the body may be separated from the handle housing.

Various configurations for a pump for oral irrigators. In one embodiment, a pump is disclosed that includes a connecting rod and a piston. The piston includes a sidewall defining a piston cavity and a rod cutout defined in the sidewall where the rod cutout enables insertions of a portion of the connecting rod into the piston cavity, where after insertion the connecting rod extends from the piston cavity past a bottom edge of the sidewall.

A toothbrush tip includes a brush head, a plurality of bristle tufts extending from the brush head, a water jet nozzle extending from the brush head, and a cover panel arranged on a rear of the toothbrush tip opposite the bristle tufts.

An oral irrigator is provided. The oral irrigator may include a base unit defining a recess, a reservoir supported by the base unit, a handle support attached to the base unit above the recess, an oral irrigator handle supported by the handle support, and a tube attached to the handle and in fluid communication with the reservoir and the handle such that fluid from the reservoir flows through the tube into the handle. The tube may include a coiled portion that is received in the recess defined by the base unit when the handle is supported by the handle support.

The present disclosure is directed to a cantilever-type pump subassembly for an oral irrigator which provides noise and vibration reduction and simpler assembly. The pump subassembly comprises: an inlet portion arranged to receive fluid from a reservoir; an outlet portion integrally secured to the inlet portion, the outlet portion arranged to receive a pressurized flow of the fluid; and, a pressurizing portion integrally secured to the inlet portion and the outlet portion. The pressurizing portion comprises: a first end having a mounting flange, wherein the pump subassembly is fixedly secured only to a gearbox housing arranged within the housing by the mounting flange.

An oral irrigator including a base and a handle. The base includes a fluid reservoir, a pump in fluid communication with the fluid reservoir, and a base wireless communication component in electrical communication with the pump. The handle is in fluid communication with the pump. The handle includes a handle wireless communication component and one or more control buttons in communication with the handle wireless communication component. The handle wireless communication component transmits control signals from the one or more control buttons to the base wireless communication component to adjust an operating parameter of the pump.

In one embodiment, an oral irrigator includes a reservoir, a base configured to support the reservoir, and a button assembly coupled to the base. The button assembly may include a button, a spring coupled to the button, and a seal coupled to the spring. The button may be movable between an original position and an actuation position. The spring may be configured to deform in response to a user input force moving the button from the original position to the actuation position, and to resiliently return the button to the original position in response to cessation of the user input force on the button. The seal may inhibit fluid from entering through the spring into the base.
