Abstract
A toothbrush is provided having a light source for signaling when a recommended brushing time interval has started and ended. In particular, the toothbrush includes a handle portion having a translucent portion configured to allow the transmission of light therefrom around substantially the entire circumference of the toothbrush. The toothbrush further includes a tip portion attached to the handle portion having a plurality of bristles extending therefrom. The tip portion is detachable from the handle portion. The toothbrush further includes a light emitting diode disposed within the handle portion proximate to the translucent portion. Finally, the toothbrush includes a control circuit disposed within the handle portion electrically connected to the light emitting diode.
Claims18
A toothbrush, comprising:
- a handle portion having a translucent portion configured to allow the transmission of light therefrom;
- a tip portion attached to said handle portion having a plurality of bristles extending therefrom;
- a light source disposed within said handle portion proximate to said translucent portion;
- and,
- a control circuit disposed within said handle portion configured to control said light source to interactively switch said light source on and off for a second predetermined time period after a delay of a first predetermined time period and for then switching said light source back on for a third predetermined time period, and said control circuit switches said light source interactively on and off on a variable frequency for a fourth predetermined time period.
A toothbrush, comprising:
- a handle portion having a translucent portion configured to allow the transmission of light therefrom, said translucent portion being configured around substantially an entire circumference of said toothbrush;
- a tip portion attached to said handle portion having a plurality of bristles extending therefrom;
- a light source disposed within said handle portion proximate to said translucent portion;
- and,
- a control circuit disposed within said handle portion configured to control said light source to interactively switch said light source on and off for a second predetermined time period after a delay of a first predetermined time period and for then switching said light source back on for a third predetermined time period.
A toothbrush comprising:
- a handle portion having a translucent portion disposed approximate to a first end of said handle portion and configured to allow the transmission of light therefrom;
- a tip portion attached to said handle portion having a plurality of bristles extending therefrom;
- a light emitting diode disposed within said handle portion approximate to said translucent portion;
- a switch connected on said handle portion;
- and
- a controller disposed within said handle portion electrically connected to said light emitting diode, said controller interactively turning said light emitting diode on and off for a second predetermined time period after a delay of a first predetermined time period after said switch is activated and said controller turning said diode on for a third predetermined time period after said second predetermined time period and said controller interactively turning said diode on and off for a fourth predetermined time period after said third predetermined time period and said controller switching said diode off after said fourth predetermined time period, and wherein the frequency said controllers turns said diode on and off increases during the fourth predetermined time period.
