Abstract
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.
Claims20
An oral irrigator comprising:
- a reservoir;
- a base that supports the reservoir;
- and
- a button assembly coupled to the base and configured to provide an input to the base, the button assembly comprising:
- a button movable between an original position and an actuation position;
- a spring coupled to the button and 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;
- and
- a light guide coupled to the button, the light guide comprising:
- an emitter surrounding a perimeter of the button;
- a light guide body optically coupled to the emitter, wherein the light guide body defines a cylindrical body that tapers along an angled plane from a top end towards a bottom end, the bottom end defining a light entrance to the light guide body, wherein the light guide body further defines a distribution cutout, wherein the distribution cutout comprises a tapered end facing the light entrance, wherein the tapered end is configured to split light emitted from a light source entering the light entrance into a first light portion and a second light portion.
An oral irrigator comprising:
- a reservoir;
- a base that supports the reservoir;
- and
- a button assembly coupled to the base, the button assembly comprising:
- a button;
- and
- a light guide coupled to the button, the light guide comprising:
- an emitter surrounding a perimeter of the button;
- and
- a light guide body in optical communication with a light source and with the emitter;
- wherein:
- the light guide body defines a cylindrical body tapered along an angled plane and a plurality of distribution cutouts;
- and
- the light source is a single light emitting diode.
An oral irrigator comprising:
- a reservoir;
- a base that supports the reservoir;
- and
- a button assembly coupled to the base, the button assembly comprising:
- a button;
- and
- a light guide coupled to the button, the light guide comprising:
- an emitter surrounding a perimeter of the button;
- a light guide body in optical communication with a light source and with the emitter;
- and
- a plurality of distribution cutouts defined by the light guide body, wherein the plurality of distribution cutouts define emission regions within the light guide body that are smaller closer to a light entrance and that are larger farther from the light entrance.
