A dental cleaning appliance includes a fluid reservoir for storing working fluid, a nozzle for delivering working fluid to the teeth of a user, a light source for illuminating the fluid reservoir and a control circuit for activating the light source to generate an alert which is conveyed to the user through the illumination of the fluid reservoir.

Cleaning appliance

A dental cleaning appliance includes a handle, a fluid reservoir for storing a working fluid, and a fluid delivery system for receiving working fluid from the reservoir, and for delivering working fluid to the oral cavity of a user. A drive unit drives movement of a bristle carrier relative to the handle. The fluid reservoir extends about at least part of the drive unit.

Dental treatment appliance

A fluid delivery system for a dental cleaning appliance includes a nozzle for delivering a burst of working fluid to the teeth of a user, and a fluid conduit for conveying working fluid to the nozzle. A body of the nozzle defines a fluid chamber and a channel for conveying working fluid from the fluid chamber to a fluid outlet from the nozzle. The fluid chamber has a tangential inlet for receiving working fluid from the fluid conduit.

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.

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. A contact member for engaging the teeth of the user is moveable relative to the nozzle as the appliance is moved along the teeth of the user. A sensor provides an output which varies with movement of contact member relative to the nozzle. A control circuit actuates the delivery of working fluid to the teeth of the user depending on the output from the sensor.

A pump assembly for a dental cleaning appliance includes a fluid chamber, a piston, and a drive. The drive rotates a coupling member having two angularly opposed pins. An arm pivotably connected to the piston has a seat for receiving one of the pins to couple the piston to the drive. Through continued rotation of the coupling member, the piston moves within the fluid chamber to draw fluid into the fluid chamber until the second detent contacts the arm to push it away from the first detent to decouple the drive from the piston. This allows a compressed spring to actuate the piston to urge a burst of fluid from the fluid chamber.
