  • Cleaning appliance
    Patent number: 11116306
    Abstract: A pump assembly for a dental cleaning appliance includes a fluid chamber, a piston, and a drive. Magnets, connected respectively to the piston and the drive, enable the drive to couple to the piston and move it within the fluid chamber to draw fluid into the fluid chamber. A stop prevents the piston from being pulled beyond a stop position so that through continued actuation of the drive the magnets separate to allow a spring to push the piston away from the stop position to urge a burst of fluid from the fluid chamber.
    Type: Grant

  • Cleaning appliance
    Patent number: 10588399
    Abstract: A fluid delivery system of a dental cleaning appliance includes a pump for drawing a working fluid through a fluid inlet, a hydraulic actuator for receiving working fluid from the pump, a drive for actuating the pump, and a nozzle having a fluid outlet for ejecting working fluid from the appliance. The drive includes a motor and a control circuit for operating the motor. The control circuit is configured to detect stalling of the motor in response to the load applied to the pump by the pressurized working fluid stored in the accumulator, and to deactivate the motor when stalling of the motor has been detected.
