Abstract
An oral care appliance and a method of controlling pressure in the oral care appliance are disclosed. The pressure inside a mouthpiece of the oral care appliance is controlled by an actuator. The actuator is triggered when a targeted threshold value of an operational characteristic is reached. Automatic control of the pressure in the mouthpiece enhances both cleaning efficiency and user comfort.

-26. (canceled)
An oral care appliance comprising:
- a mouthpiece configured to deform in response to pressure variations inside a cavity during a brushing cycle, wherein the cavity is formed by at least a portion of the mouthpiece, and wherein the brushing cycle comprises at least one contraction phase and at least one relaxation phase of the mouthpiece;
- and
- an actuator configured to control at least one of the contraction phase and the relaxation phase by regulating the pressure inside the cavity, wherein the actuator is triggered in response to at least one operational characteristic reaching a targeted threshold value.
A method of controlling pressure in an oral care appliance, the method comprising:
- varying pressure inside a cavity to deform a mouthpiece during a brushing cycle, wherein the cavity is formed by at least a portion of the mouthpiece, wherein the brushing cycle comprises at least one contraction phase and at least one relaxation phase of the mouthpiece;
- and
- regulating the pressure inside the cavity to control at least one of the contraction phase and the relaxation phase, wherein an actuator is triggered to regulate the pressure inside the cavity when at least one operational characteristic reaches a targeted threshold value.
