Abstract

A dental cleaning appliance includes a handle; an electronic display, and a control circuit for activating the display. The handle includes a body and a transparent panel connected to the body. The panel defines a trough-shaped recess beneath which the display is located.

Claims

1. A dental cleaning appliance comprising:

a handle;

a display; and

a control circuit for activating the display,

wherein the handle comprises a body and a transparent panel connected to the body, the panel defining a trough-shaped recess, and wherein the display is located beneath the recess.

2. The appliance of claim 1, wherein the recess is concave in shape.

3. The appliance of claim 1, wherein the recess is defined by a concave wall of the panel.

4. The appliance of claim 3, wherein the concave wall extends substantially the length of the recess.

5. The appliance of claim 3, wherein the body is substantially cylindrical in shape, and wherein the radius of curvature of the concave wall is smaller than the radius of curvature of the body.

6. The appliance of claim 3, wherein the panel is formed from a different material from at least an adjoining portion of the body.

7. The appliance of claim 6, wherein said at least an adjoining portion of the body is overmolded on to the panel.

8. The appliance of claim 6, wherein the body of the handle is formed from a blend of polycarbonate (PC) and acrylnitrile-butadiene-styrene (ABS) materials.

9. The appliance of claim 1, wherein the panel is formed from a transparent polycarbonate material.

10. The appliance of claim 1, wherein the handle comprises at least one user-operable button having a flexible membrane which is pressed by the user to operate the button, and wherein the flexible membrane is molded on to the panel.

11. The appliance of claim 10, wherein the flexible membrane is formed from a thermoplastic elastomeric material.

12. The appliance of claim 1, wherein the body comprises an end surface, and wherein the recess adjoins the end surface of the body.

13. The appliance of claim 1, wherein the display comprises an elongate display.

14. The appliance of claim 1, wherein the display comprises an OLED display.

15. A handle for a dental cleaning appliance, the handle being detachably connectable to a cleaning tool of the appliance, the handle comprising:

a body;

a transparent panel connected to the body, the panel defining a trough-shaped recess;

a display; and

a control circuit for activating the display,

wherein the display is located beneath the recess.

16. The handle of claim 15, wherein the recess is concave in shape.

17. The handle of claim 15, wherein the recess is defined by a concave wall of the panel.

18. The handle of claim 17, wherein the concave wall extends substantially the length of the recess.

19. The handle of claim 17, wherein the body is substantially cylindrical in shape, and wherein the radius of curvature of the concave wall is smaller than the radius of curvature of the body.

20. The handle of claim 17, wherein the panel is formed from a different material from at least an adjoining portion of the body.

21. The handle of claim 20, wherein said at least an adjoining portion of the body is overmolded on to the panel.

22. The handle of claim 20, wherein the body is formed from a blend of polycarbonate (PC) and acrylnitrile-butadiene-styrene (ABS) materials.

23. The handle of claim 15, wherein the panel is formed from a transparent polycarbonate material.

24. The handle of claim 15, wherein the handle comprises at least one user-operable button having a flexible membrane which is pressed by the user to operate the button, and wherein the flexible membrane is molded on to the panel.

25. The handle of claim 24, wherein the flexible membrane is formed from a thermoplastic elastomeric material.

26. The handle of claim 15, wherein the body comprises an end surface, and wherein the recess adjoins the end surface of the body.

27. The handle of claim 15, wherein the display comprises an elongate display.

28. The handle of claim 15, wherein the display comprises an OLED display.
