A dental cleaning appliance includes a nozzle having a fluid chamber, a fluid outlet and a channel extending between the fluid chamber and the fluid outlet. A water reservoir provides water to a pump for generating a burst of pressurized water, which is supplied to the nozzle by a fluid conduit. Following the delivery of the burst of water to the teeth of the user, a valve draws water back into the fluid chamber from the channel to prevent that water from dripping from the fluid outlet before the next water burst is generated by the pump. Simultaneously, air may be drawn into the fluid chamber, for example, through the fluid outlet, for mixing with the next water burst to generate a fluid burst for delivery to the user's teeth.

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.

A dental cleaning appliance includes a handle, a display, and a control circuit for activating the display. The handle includes a body which is gripped by a user during use of the appliance, a transparent panel beneath which the display is located, and a layer of reflective material disposed on an external surface of the panel and through which, during use, the activated display is visible to the user.

A dental cleaning appliance includes a handle; an electronic display, and a control circuit for activating the display. The handle includes a body and a transparent panel connected to the body. The panel defines a trough-shaped recess beneath which the display is located.

The present disclosure relates to a hermetic tooth cleaning device, and more particularly, to a hermetic tooth cleaning device including: a main body which includes an outer case; a cleaning body which is coupled to the main body, and has an internal fluid conduit formed therein such that at least one nozzle is formed to be opened at one end of the internal fluid conduit, and an accommodating portion is formed at the other end of the internal fluid conduit; a connecting unit which couples the main body and the cleaning body, and has a connecting flow path formed therein, one side fixedly coupled to the main body, and the other side inserted into the accommodating portion; and a first sealing unit which is provided between the cleaning body and the connecting unit, and has a hollow space formed therein, thereby preventing a loss of positive pressure or negative pressure and a leak of gargling water or a cleaning solution by improving sealing performance of a flow path that connects a drive unit and the nozzle.

A dental treatment appliance transmits a pulsed light signal towards the oral cavity and captures images of the oral cavity from light returned from the oral cavity. A controller actuates the treatment of the oral cavity of the user depending on the captured images.

Provided is an oral care implement (1), comprising: a body (100); a carrier (130) connected to the body (100) and movable relative to the body (100), the carrier carrying one or more cleaning elements (134); a carrier drive mechanism (200) operable to drive movement of the carrier (130) relative to the body (100); an auxiliary device (400); and an auxiliary device drive mechanism (600) that is selectively engagable with the carrier drive mechanism (200) during operation of the carrier drive mechanism, so as to selectively operate the auxiliary device (400) during movement of the carrier (130) relative to the body (100). Also provided is a method of operating the oral care implement (1), and a kit of parts for an oral care implement.
