Abstract

A universal base for an electric toothbrush has a body comprising a top surface, a bottom surface, and a side surface therebetween. The base can be coupled with the toothbrush for wireless communication therebetween. The base includes a charging component for inductively charging the electric toothbrush, a Bluetooth component for communicating usage data received from the toothbrush during a brushing session, an analyzing component for instantaneous processing of the usage data received from the toothbrush, a timer-clock component for displaying either a count-up or a countdown of the brushing session during the brushing session and time of day before and after the brushing session, and a multi-functional light component for instantaneously communicating, during the brushing session, at least one element of the usage data.

Claims (29)

1 . A universal base ( 100 ) for an electric toothbrush ( 155 ), the base having a body ( 101 ) comprising a top surface ( 110 ), a bottom surface ( 120 ) opposite to the top surface ( 110 ), and a side surface ( 130 ) extending between the top and bottom surfaces ( 110 , 120 ),

wherein the base ( 100 ) is structured and configured to be coupled with the electric toothbrush ( 155 ) for wireless communication therebetween,

wherein the base ( 100 ) comprises:

a charging component ( 150 ) for inductively charging the toothbrush ( 155 ) when the toothbrush ( 155 ) is placed upon the top surface ( 110 ) of the base ( 100 );

a Bluetooth component ( 160 ) for receiving usage data from the electric toothbrush ( 155 ) during a brushing session;

an analyzing component ( 180 ) arranged for instantaneous processing of the usage data received from the electric toothbrush ( 155 ) during the brushing session;

a timer-clock component ( 190 ), including a timer-clock display ( 195 ) located on the side surface, for displaying (a) either a count-up or a countdown of the brushing session during the brushing session, and (b) time of day before and after the brushing session; and

a multi-functional light component ( 200 ) located on the top surface ( 110 ) wherein the light component ( 200 ) comprises at least six segments ( 210 a , 210 b , 210 c , 210 x , 210 y , 210 z ) arranged for instantaneously communicating usage data during the brushing session with respect to brushing buccal, lingual, occlusal, and incisal surfaces of maxillary and mandibular teeth including at least six portions of the teeth comprising a portion including upper left posterior dentition, a portion including upper right posterior dentition, a portion including upper anterior dentition, a portion including lower left posterior dentition, a portion including lower right posterior dentition, and a portion including lower anterior dentition.

2 . The universal base of claim 1 , wherein the at least one element of the received usage data is selected from the group consisting of a battery charging status, a pressure applied by a user during the brushing session, a position or orientation of the toothbrush relative to the teeth of the user, a portion of the teeth being brushed, a progress of the brushing session, an indication that the brushing session is completed, an indication that the brushing session exceeded a threshold of time or a threshold of coverage, and any combination thereof.

3 . The universal base of claim 1 , wherein the light component ( 200 ) is structured and configured to be visible during the brushing session and invisible before and after the brushing session.

4 . The universal base of claim 1 , wherein the light component ( 200 ) is structured and configured to emit light selected from the group consisting of ambient light and night light before and after the brushing session.

5 . The universal base of claim 1 , wherein the light component ( 200 ) is structured and configured to emit light having at least one of a first personalized color and a first personalized brightness chosen by a first user.

6 . The universal base of claim 5 , wherein the light component ( 200 ) is structured and configured to emit light having at least one of a second personalized color and a second personalized brightness chosen by a second user, wherein the first personalized color differs from the second personalized color and/or the first personalized brightness differs from the second personalized brightness.

7 . The universal base of claim 1 , wherein the base ( 100 ) comprises an audio component including a speaker ( 199 ).

8 . The universal base of claim 1 , wherein the base ( 100 ) comprises a WLAN component ( 170 ) for communicating the usage data between the base and at least one of a smart-device application, another universal base, and a cloud.

9 . The universal base of claim 1 , wherein the body ( 101 ) of the base ( 100 ) has a substantially circular shape, wherein each of the top and bottom surfaces ( 110 , 120 ) is substantially round and the side surface ( 130 ) is annular, the top surface having an outer perimeter (P) having a first diameter (D 1 ) from about 45 mm to about 90 mm, wherein the multi-functional light component ( 200 ) is disposed at the top surface ( 110 ) adjacent to the outer perimeter (P) thereof and comprises a plurality of curved segments ( 210 ) positioned substantially equidistantly from the outer perimeter P, the plurality of curved segments ( 210 ) forming, in combination with one another, a circle having a second diameter (D 2 ) concentric with the first diameter (D 1 ), wherein the second diameter (D 2 ) is from about 35 mm to about 75 mm.

10 . The universal base of claim 9 , wherein the side surface ( 130 ) is disposed at an included angle (A) of about 90 degrees relative to the bottom surface ( 120 ).

11 . The universal base of claim 8 , wherein the side surface ( 130 ) is disposed at an included angle (A) of less than about 90 degrees relative to the bottom surface ( 120 ).

12 . The universal base of claim 10 , wherein the included angle (A) is at least 40 degrees.

13 . The universal base of claim 8 , wherein the top surface ( 110 ) and the side surface ( 130 ) are substantially smooth and devoid of sharp projections, recesses, edges, and corners susceptible to accumulation of residual dentifrice and products of waste resulting from brushing.

14 . The universal base of claim 9 , wherein the base ( 100 ) is structured and configured to receive, for wireless charging, the electric toothbrush ( 155 ) having a maximal equivalent diameter (dmax), the handle ( 155 ) to be disposed in a vertical orientation on the top surface ( 110 ) of the base ( 100 ) for inductive coupling therewith, wherein the first diameter (D 1 ) is at least 1.5 times greater than the maximal equivalent diameter (dmax) of the toothbrush ( 155 ).

15 . The universal base of claim 14 , wherein the first diameter is at least 2 times greater than the maximal equivalent diameter of the toothbrush.

16 . The universal base of claim 1 , wherein the base ( 100 ) comprises a magnetic element ( 140 ) structured and configured to form a magnetic connection with the electric toothbrush ( 155 ) when the toothbrush ( 155 ) is received by the base ( 100 ) for charging.
