Abstract
The invention relates to a device for cleaning teeth. The invention relates particularly to a hand piece in an electric teeth cleaning device comprising a coupling part for coupling various cleaning tools, a drive mechanism for driving the coupled cleaning tools and a control device for controlling the drive mechanism.
The invention also relates to said cleaning tools. According to the invention, the hand piece contains an electronic operating lock device which is released only when the cleaning tool is coupled to the hand piece by a coded releasing element disposed on the cleaning tool.
The invention also relates to said cleaning tools. According to the invention, the hand piece contains an electronic operating lock device which is released only when the cleaning tool is coupled to the hand piece by a coded releasing element disposed on the cleaning tool.
Claims (16)
1. A handle section of an electric dental cleaning device that is capable of use with a cleaning tool that includes a first coil configured to receive and transmit electromagnetic waves, the handle section comprising:
a handle housing;
a coupling section at an end of the handle housing for coupling a cleaning tool thereto;
a detector and a second coil configured to transmit and receive electromagnetic waves to and from a first coil in a cleaning tool;
a drive mechanism for driving a cleaning tool coupled to the coupling section; and a control device located in or on the handle housing that controls the drive mechanism and comprises an interlock device for preventing operation of the drive mechanism, wherein the interlock device is deactivated when a cleaning tool is coupled to the coupling section and provides an electromagnetic signal to the second coil and detector, thereby enabling operation of the drive mechanism.
a handle housing;
a coupling section at an end of the handle housing for coupling a cleaning tool thereto;
a detector and a second coil configured to transmit and receive electromagnetic waves to and from a first coil in a cleaning tool;
a drive mechanism for driving a cleaning tool coupled to the coupling section; and a control device located in or on the handle housing that controls the drive mechanism and comprises an interlock device for preventing operation of the drive mechanism, wherein the interlock device is deactivated when a cleaning tool is coupled to the coupling section and provides an electromagnetic signal to the second coil and detector, thereby enabling operation of the drive mechanism.
2. The handle section of claim 1, wherein a coupled cleaning tool comprises a brush attachment.
3. The handle section of claim 1, further comprising a switch disposed on the housing and associated with the drive mechanism to activate the detector, wherein said drive mechanism is turned on upon a positive response of the detector.
4. The handle section of claim 1, further comprising a switch disposed on the housing and associated with the drive mechanism to activate the detector, wherein said drive mechanism is turned on upon deactivation of the interlock device.
5. A cleaning tool for an electric dental cleaning device that is capable of use with a handle section including a detector and a first coil configured to transmit and receive electromagnetic waves to and from the cleaning tool, the cleaning tool comprising:
a cleaning tool body for removably coupling to a handle section;
a cleaning section at a distal end of the cleaning tool body;
a coupling section at a proximal end of the cleaning tool body to effect coupling to a handle section of an electric dental cleaning device; and an interlock canceling element disposed in or on the cleaning tool body;
wherein the interlock canceling element comprises a transponder tuned to a detector located in or on a handle section; and a second coil configured to transmit and receive electromagnetic waves to and from a first coil in a handle section;
wherein the interlock canceling element deactivates an interlock device disposed in a handle section upon coupling the cleaning tool with a handle section, thereby enabling operation of a dental cleaning device.
a cleaning tool body for removably coupling to a handle section;
a cleaning section at a distal end of the cleaning tool body;
a coupling section at a proximal end of the cleaning tool body to effect coupling to a handle section of an electric dental cleaning device; and an interlock canceling element disposed in or on the cleaning tool body;
wherein the interlock canceling element comprises a transponder tuned to a detector located in or on a handle section; and a second coil configured to transmit and receive electromagnetic waves to and from a first coil in a handle section;
wherein the interlock canceling element deactivates an interlock device disposed in a handle section upon coupling the cleaning tool with a handle section, thereby enabling operation of a dental cleaning device.
6. The cleaning tool of claim 5, wherein the cleaning tool comprises a brush attachment.
7. The cleaning tool of claim 5, wherein the interlock canceling element provides an encoding configured to be detectable by a detector disposed in a handle section.
8. The cleaning tool of claim 5, wherein the cleaning section comprises a bristle section, an interproximal cleaning section, a gum massager section, or a tongue cleaning section.
9. The cleaning tool of claim 5, wherein the cleaning tool body comprises a fitting for positioning the cleaning tool body in a predetermined orientation when the cleaning tool is joined to a handle section.
10. The cleaning tool of claim 9, wherein the fitting of the cleaning tool body transmits a driving motion of a handle section to the cleaning tool.
11. The handle section of claim 1, wherein the handle housing further comprises a storage battery electrically connected to the drive mechanism.
12. The handle section of claim 1, wherein the second coil located in the handle section and a first coil located in a cleaning tool are disposed in relative opposite arrangement when a cleaning tool is coupled to the handle section.
13. The cleaning tool of claim 5, wherein the transponder is located within the cleaning tool body.
14. The cleaning tool of claim 5, wherein the transponder is located within or on a slip-on ring that connects to the cleaning tool body.
15. The cleaning tool of claim 5, wherein the second coil is located within or on a slip-on ring that connects to the cleaning tool body.
16. The cleaning tool of claim 5, wherein the transponder provides a signal that identifies the cleaning tool.
