Abstract: This disclosure is directed to systems and methods for automatically resetting pause control on an oral irrigator. The methods use a resilient device which stores potential energy when the oral irrigator is turned on or the pause control feature is turned off. The stored potential energy is then released and switches the pause control feature on when the oral irrigator is turned off or placed on its stand. The pause control assembly includes a slider coupled to the valve, where the slider has a first protrusion; a return which makes contact with a first protrusion of the slider; and a stopper, which in the closed position prevents the return from moving. The automatic pause control reset can also include a pressure plate and a pressure chamber which respond to a change in fluid pressure to permit the opening of a pause control valve.

Abstract: An oral irrigator having an irrigator tip, the tip including a handle portion, a tip portion, a channel in fluid communication with the tether and arranged within the handle portion and the tip portion, and an actuator located on or within the handle portion, the actuator arranged to at least partially altar a flow of a fluid through the channel. The oral irrigator further includes a housing, the housing having a reservoir in fluid communication with a pump sub-assembly, a sensor arranged to measure a first pressure or first electrical load within the pump sub-assembly, and a control unit arranged to control an operational current provided to the pump sub-assembly where operation of the actuator produces a second pressure or electrical load measured by the sensor and the control unit is arranged to alter the operational current of the motor in response to the change.

Abstract: The present disclosure is directed to systems and methods for electronic control of an operating level of an oral irrigator, particularly when flow from the oral irrigator is paused. Methods for controlling an operational level include: determining an operational level of the oral irrigator, including whether the operational level is a standby mode; receiving sensor data from one or more sensors; determining whether a key sensor indicator is above, below, or at a threshold. If the key sensor indicator is above a threshold, the operational level is changed to standby mode. If the key sensor indicator is at or below the threshold, the operational level remains at the current level. If the key sensor indicator is below the threshold, and the current operational level is the standby mode, the operational level is changed to the operational level set before entering standby mode.

Abstract: A connection mechanism (18) for connecting a workpiece (12) to a handle assembly (14) of an oral care device (10). A collet (30) has an axially extending beam (32) and a radially extending protrusion (34). The protrusion has a latching surface (44) that prevents disengagement of the workpiece from the handle assembly when in a locked configuration. A cam feature (40) is configured to convert an axial force exerted on the collet into radial deflection of the beam to transition the connection mechanism to an unlocked configuration in which the latching surface is disengaged from the corresponding surface of the workpiece. The beam is configured to return to the default position after the axial force is released due to strain energy in the beam resulting from the radial deflection.
