The present invention relates to is a nozzle for an oral irrigator, comprising: a nozzle body; and a housing, in which an outlet is defined, wherein the housing is connected to one end of the nozzle body-(242), and defines, with the nozzle body, an accommodating cavity in communication with the air. Fluid for oral irrigation enters the accommodating cavity through the nozzle body, and is sprayed out via the outlet after being mixed with the air.

The invention discloses a tooth cleaner mainly composed of a brace and a handle, the brace comprises an upper tooth socket and a lower tooth socket, a plurality of small open holes which are arranged at intervals are distributed in the upper tooth socket and the lower tooth socket, one end of each of the small open holes is connected with a first guide pipe embedded into the brace, the other ends of the first guide pipes extend into the handle and are connected with a pump outlet of a pump module arranged inside the handle, the pump module also comprises a pump air inlet and a pump water inlet, the pump water inlet of the pump module is connected with a water storage module in the handle by a guide pipe, and the pump air inlet of the pump module communicates with an air inlet in the surface of the handle by a guide pipe. By using the tooth cleaner, the problems of poor cleaning and atomizing effects and poor user experience of the original tooth cleaner are solved.

An apparatus and method for purging a dental air/water syringe comprises at least one of a button hold-down device for holding down at least one button of the syringe for discharging fluid therefrom and a collection container for collecting the discharged fluid. The button hold-down device includes axially spaced contact surfaces for contacting a syringe body and the button so that the device is supported mounted on the syringe body in a working position. The collection container features an interior perforated false bottom wall under which is formed a collection space where the discharged fluid collects, and a drain is communicated with the collection space for removing the collected fluid therefrom. The drain can be connected to a saliva ejector for removal of the fluid by suction.
