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: 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.
