Abstract

In one embodiment, the invention may be a teeth cleaning device including: a first support structure comprising a first dentature channel configured to receive at least a first portion of a dentature of a user; a plurality of teeth cleaning pads located within the first dentature channel; a plurality of air bladders operably coupled to the teeth cleaning pads; an air-flow subsystem operably coupled to the air bladders; and a control unit operably coupled to the air-flow subsystem, the control unit configured to: (1) pressurize the air bladders with external air in a pressurization mode; and (2) transfer air between select ones of the air bladders in a cleaning mode.

First claim

What is claimed is:

1. A teeth cleaning device comprising:
a first support structure comprising a first dentature channel configured to receive at least a first portion of a dentature of a user;
a plurality of teeth cleaning pads located within the first dentature channel;
a plurality of air bladders operably coupled to the teeth cleaning pads;
an air-flow subsystem operably coupled to the air bladders, the air-flow subsystem comprising:
an air pump;
at least one valve; and
at least one transfer pump; and

a control unit operably coupled to the air-flow subsystem, the control unit configured to: (1) pressurize the air bladders with external air in a pressurization mode; and (2) transfer air between select ones of the air bladders in a cleaning mode;
wherein the control unit controls pressurization of the air bladders and transfers air between the select ones of the air bladders by controlling the air pump, the at least one valve, and the at least one transfer pump.

2. The device according to claim 1 , wherein each teeth cleaning pad is integrally formed with one of the air bladders.

3. The device according to claim 1 , wherein the plurality of air bladders comprises a first set of air bladders and a second set of air bladders, each of the first set of air bladders and the second set of air bladders comprising at least one of the air bladders.

4. The device according to claim 3 , wherein:
the first set of the air bladders comprises a first air bladder located adjacent a facial wall of the first dentature channel; and
the second set of the air bladders comprises a second air bladder located adjacent a glossal wall of the dentature channel so as to oppose the first air bladder.

5. The device according to claim 3 , wherein:
the first set of the air bladders comprises a first air bladder located adjacent a facial wall of the dentature channel and a second air bladder located adjacent a glossal wall of the dentature channel; and
the second set of the air bladders comprises a third air bladder located adjacent the glossal wall of the dentature channel and a fourth air bladder located adjacent the facial wall of the dentature channel, the first air bladder opposing the third air bladder and the second air bladder opposing the fourth air bladder.

6. The device according to claim 3 , further comprising a second support structure comprising a second dentature channel configured to receive at least a second portion of the dentature of the user.

7. The device according to claim 6 , wherein:
the first set of the air bladders comprises a first air bladder located adjacent a first channel floor of the first dentature channel; and
the second set of the air bladders comprises a second air bladder located adjacent a second channel floor of the second dentature channel.

8. The device according to claim 1 , wherein the at least one valve has an open position for the air pump to pressurize one or more of the air bladders and a closed position to seal the one or more of the air bladders from the air pump, wherein when one or more of the air bladders are pressurized, the teeth cleaning pads are displaced into the dentature channel.

9. The device according to claim 1 , wherein the air-flow subsystem comprises a pressure release valve operably coupled to the air bladders.

10. The device according to claim 1 , wherein each air bladder is formed of one of a silicon rubber or a polyurethane.

11. The device according to claim 1 , wherein each air bladder has a Shore hardness between and including 15-30 A.

12. The device according to claim 1 , wherein each teeth cleaning pad comprises a plurality of teeth cleaning elements.

13. The device according to claim 12 , wherein the teeth cleaning elements are formed of a polyurethane material.

14. The device according to claim 12 , wherein the teeth cleaning elements are formed of a material having a Shore hardness between and including 30-40 A.

15. A teeth cleaning device device comprising:
a first support structure comprising a first dentature channel configured to receive at least a first portion of a dentature of a user;
a plurality of teeth cleaning pads located within the first dentature channel;
a plurality of air bladders operably coupled to the teeth cleaning pads;
an air-flow subsystem operably coupled to the air bladders; and
a control unit operably coupled to the air-flow subsystem, the control unit configured to: (1) pressurize the air bladders with external air in a pressurization mode; and (2) transfer air between select ones of the air bladders in a cleaning mode;
wherein the plurality of air bladders comprises a first set of air bladders, a second set of air bladders, a third set of air bladders, a fourth set of air bladders, a fifth set of air bladders, and a sixth set of air bladders, each set of air bladders comprising at least one of the air bladders, the air-flow subsystem comprising further comprising:
a first transfer pump operably coupled between the first set of the air bladders and the second set of the air bladders;
a second transfer pump operably coupled between the third set of the air bladders and the fourth set of the air bladders; and
a third transfer pump operably coupled between the fifth set of the air bladders and the sixth set of the air bladders.
