Abstract
A toothbrush with a handle having a base, a body, and a head. The body having a first section and a second section forming an oblique angle. A projector of a beam of light located within the handle. The toothbrush having at least one bristle attached to the head. The toothbrush having a grip attached to the base. A method of using a toothbrush including the step of gripping the toothbrush. The method further including the step of engaging the projector of a beam of light. The method still further including the step of utilizing the toothbrush while the projector of a light beam is activated.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A toothbrush comprising:
a handle having a base, a body, and a head; the body having a first section and a second section forming an oblique angle; a projector of a beam of light located within the handle; at least one bristle attached to the head; a grip attached to the base.
2 . The toothbrush of claim 1 further comprising a switch for control of the projector of a beam of light from a non-illuminating position to an illuminating position.
3 . The illuminated toothbrush handle of claim 2 wherein the switch is a flexible member attached to the base.
4 . The toothbrush of claim 3 further comprising a timing circuit limiting the operation of the projector of a beam of light to approximately 60 seconds.
5 . The toothbrush claim 4 wherein the first section has a chamber therein, the projector of a beam of light located within the chamber.
6 . The toothbrush of claim 5 wherein a light beam is transmitted from the projector, the light beam partially reflected off an interface between the chamber and the first section, the light beam partially refracted off the interface between the chamber and the first section.
7 . The toothbrush of claim 6 wherein the light beam is partially reflected off of an interface between the second section and atmosphere toward the head, the light beam partially refracted into the atmosphere.
8 . The toothbrush of claim 7 wherein the light beam is partially reflected off of an interface between the head and the bristle, the light beam partially refracted into the bristle.
9 . The toothbrush of claim 8 wherein the light beam is partially reflected off of at least one metallic flake imbedded in the body.
10 . A toothbrush comprising:
a handle having a base, a body, and a head; the body having a chamber therein; a projector of a beam of light within the chamber; at least one bristle attached to the head. a grip attached to the base.
11 . The toothbrush of claim 10 further comprising a switch for control of the projector of a beam of light from a non-illuminating position to an illuminating position.
12 . The illuminated toothbrush handle of claim 11 wherein the switch is a flexible member attached to the base.
13 . The toothbrush of claim 12 further comprising a timing circuit limiting the operation of the projector of a beam of light to approximately 60 seconds.
14 . The toothbrush of claim 13 wherein a light beam is transmitted from the projector, the light beam partially reflected off an interface between the chamber and the body, the light beam partially refracted off the interface between the chamber and the body.
15 . The toothbrush of claim 14 wherein the base has a circumferential groove therein, the circumferenital groove located adjacent the chamber, the circumferential groove having a centerline.
16 . The toothbrush of claim 15 wherein a centerline of the chamber is in offset alignment with the circumferential groove centerline.
17 . A method of using a toothbrush having a handle and an illumination circuit, the handle having a base, a body, and a head, the illumination circuit having a projector of a beam of light connected to a switch, the method comprising:
gripping the toothbrush; engaging the switch for completing the illumination circuit; activating a projector of a light beam within the toothbrush; utilizing the toothbrush while the projector of a light beam is activated.
18 . The method of claim 17 wherein the step of engaging the switch comprises longitudinal pressing a grip attached to the base of the toothbrush towards the body.
19 . The method of claim 18 further comprising the step of intermittent engaging the projector of a light beam.
20 . The method of claim 19 further comprising the step of deactivating the projector of a light beam after approximately 60 seconds.Cited by (0)
