Abstract

Various operational mode arrangements of an electric toothbrush ( 10 ) include pre-programming a controller portion ( 16 ) of the electric toothbrush such that a single brushing event of approximately two minutes comprises automatically at least two different operating modes and specified times for each mode. Another operational mode includes the capability of operating the on/off button ( 20 ) of the toothbrush within a specified short time following termination of a normal brushing event to provide the user a specified additional time, e.g. 30 seconds of toothbrush action. A special toothbrush interface arrangement includes a display ( 80 ) which encourages children to maintain brushing for the full brushing period. This is accomplished through sequential illustration of the progress of an article from an initial state to a final desired state as the toothbrush is used for increasing portions of a full brushing time period. In another embodiment, a toothbrush ( 120 ) includes a capability of adjusting the performance/operating characteristics in accordance with the age of a child user.

First claim

What is claimed is:

1. A system for extending the time of automatic operation of an electric toothbrush, comprising:
a control system for the toothbrush which controls the operation of a brushhead portion of the toothbrush, the control system configured to have at least two operating modes comprising a normal brushing mode and an extended brushing mode,
said normal brushing mode having a first predetermined amount of time for brushing operation of the toothbrush, wherein said control system is configured to automatically terminate brushing operation after said first predetermined amount of time for brushing operation,
said extended brushing mode having a pre-programmed capability of providing a second predetermined amount of additional time for brushing operation of the toothbrush within a predetermined period of time subsequent to the termination of the normal brushing mode, the second predetermined amount of additional time being substantially less than the first predetermined amount of time of the normal brushing mode,
wherein the control system is configured to provide the additional time for brushing operation of the toothbrush during the extended brushing mode only upon actuation of a control element by a user within said predetermined period of time following termination of the normal brushing mode.

2. The system of claim 1 , wherein the amount of additional time is configured, in response to a setup command provided by the user to the control system.

3. The system of claim 1 , wherein the additional time is within the range of 20 to 40 seconds.

4. The system of claim 1 , wherein the additional time is approximately thirty seconds.

5. The system of claim 1 , wherein the control element is an on/off switch for the toothbrush.

6. The system of claim 1 , wherein said predetermined period of time for actuation of the control element is within the range of 0 to 10 seconds.

7. The system of claim 1 , wherein the toothbrush includes a user interface and wherein the control system is programmed to permit selection of a mode of operation of the toothbrush during the additional time period which is different than the mode of operation during an immediate past brushing event.
