Patent number: 11744689Abstract: A dental cleaning appliance includes a handle and a fluid delivery system. The fluid delivery system includes a nozzle for delivering a burst of working fluid to the teeth of a user, and a moveable fluid conduit which is moveable about an axis relative to the handle. The nozzle is moveable with the fluid conduit, which is biased for movement about the axis in a direction which urges the nozzle against a user's teeth during use of the appliance.Type: GrantFiled: May 11, 2016Date of Patent: September 5, 2023Assignee: Dyson Technology LimitedInventors: Thomas James Dunning Follows, William John Bex-Russell, Timothy Nicholas Stickney, Robert Lawrence Tweedie

Patent number: 11413125Abstract: A dental cleaning appliance includes a handle and a fluid delivery system for delivering a burst of working fluid to the teeth of a user. Part of the fluid delivery system is moveable relative to the handle as the appliance is moved along the teeth of the user. A sensor provides an output which varies with movement of that part of the fluid delivery system relative to the handle. A control circuit actuates the delivery of working fluid to the teeth of the user depending on the output from the sensor.Type: GrantFiled: June 5, 2015Date of Patent: August 16, 2022Assignee: Dyson Technology LimitedInventors: Thomas James Dunning Follows, William John Bex-Russell, Stephen Benjamin Courtney, Graham Charles Lemon, Jason Godfrey Jones

Patent number: 11076939Abstract: A fluid delivery system of a dental cleaning appliance includes a fluid inlet, a pump for drawing a working fluid through the fluid inlet, a hydraulic accumulator for receiving working fluid from the pump, a nozzle having a fluid outlet, and a valve located between the accumulator and the nozzle. The valve has an open position for enabling the accumulator to deliver a burst of working fluid to the nozzle, and a closed position for enabling the accumulator to be replenished under the action of the pump. A control circuit actuates the pump and controls the position of the valve.Type: GrantFiled: April 25, 2016Date of Patent: August 3, 2021Assignee: Dyson Technology LimitedInventors: Thomas James Dunning Follows, William John Bex-Russell, Stephen Benjamin Courtney, Jason Godfrey Jones

Patent number: 9820563Abstract: A dental cleaning appliance includes a fluid delivery system for delivering a burst of working fluid to the teeth of a user; and a control circuit for controlling the delivery of the burst of working fluid to the teeth of a user. The appliance has a first operational mode in which the delivery of the burst of working fluid to the teeth of a user is inhibited and a second operational mode in which the burst of working fluid to the teeth of a user is permitted. During use of the appliance, the control circuit is arranged to effect a transition between the first operational mode and the second operational mode automatically depending on a detected operational parameter of the appliance.Type: GrantFiled: May 11, 2016Date of Patent: November 21, 2017Assignee: Dyson Technology LimitedInventors: Thomas James Dunning Follows, William John Bex-Russell, Timothy Nicholas Stickney, Stephen Benjamin Courtney, Graham Charles Lemon, Jason Godfrey Jones
