Abstract
Official abstract text for this publication.
A dental cleaning appliance includes a handle, a fluid delivery system for delivering working fluid to the teeth of a user, and a control circuit for actuating the delivery of working fluid to the teeth of the user depending on a received input. For each input, the control circuit is arranged to actuate the delivery of a series of bursts of working fluid to the teeth of the user.
First claim
Opening claim text (preview).
The invention claimed is: 1. A dental cleaning appliance comprising: a handle; a fluid delivery system for delivering working fluid to the teeth of a user; and a control circuit for actuating the delivery of working fluid to the teeth of the user depending on a received input; wherein the control circuit is arranged to actuate the delivery of a series of bursts of working fluid to the teeth of the user in response to a detected change in the received input, and wherein the received input is an output from a sensor. 2. The appliance of claim 1 , wherein the sensor is a motion detection sensor. 3. The appliance of claim 1 , wherein the sensor is a Hall effect sensor. 4. The appliance of claim 1 , wherein the control circuit is configured to actuate the delivery of working fluid to the teeth of the user depending on the rate of change of the output from the sensor. 5. The appliance of claim 1 , wherein the sensor is located in the handle. 6. The appliance of claim 1 , wherein the fluid delivery system comprises a source of pressurized working fluid and a valve, and the control circuit is configured to open the valve to deliver a burst of working fluid to the teeth of a user. 7. The appliance of claim 6 , wherein the source of pressurized working fluid comprises a fluid chamber, and wherein the fluid chamber has a capacity in the range from 0.1 to 1 ml. 8. The appliance of claim 7 , wherein the capacity of the fluid chamber is substantially the same as the volume of a single series of bursts of working fluid. 9. The appliance of claim 7 , wherein the capacity of the fluid chamber is greater than the volume of a single series of bursts of working fluid. 10. The appliance of claim 6 , wherein the valve is a solenoid valve. 11. The appliance of claim 1 , wherein, within a series, the time period between bursts of working fluid is substantially the same. 12. The appliance of claim 1 , wherein, within a series, the time period between bursts of working fluid is in the range from 1 to 25 ms. 13. The appliance of claim 1 , wherein, within a series, the number of bursts of working fluid is in the range from two to ten. 14. The appliance of claim 1 , wherein, within a series, the bursts have substantially the same volume. 15. The appliance of claim 1 , wherein each burst of working fluid has a volume in the range from 0.05 to 0.5 ml. 16. The appliance of claim 1 , wherein the working fluid is a liquid working fluid.
