    摘要： An oral care appliance using a jet-type fluid flow And mechanical action An oral care appliance comprises: a gas-liquid cleaning assembly which includes a fluid flow pump assembly (46); a source of liquid (50); and a source of gas (12). The pump assembly is in operative communication with the sources of fluid and gas to produce a jet pattern of gas-injected fluid slugs, directed to a nozzle assembly (80) from which the resulting slugs are directed to the teeth, wherein the individual fluid slugs in the jet flow have a volume in the range of 0.05-0.5 ml per orifice, a diameter in the range of 0.1-2 mm and a repetition rate within the range of 2 Hz to 20 Hz. The appliance further includes a mechanical teeth cleaning assembly, in combination with the gas-liquid assembly, which includes a drive system (160) and a brush assembly in operative contact with the drive system, the brush assembly having a set of bristles (152) at the distal end thereof, wherein in operation, the nozzle assembly is positioned within the brush assembly.

    摘要： The appliance (10, FIG. 1) includes a body portion (27) and a nozzle portion (30) through which a spray of liquid droplets exits from a distal end thereof for cleaning of dental regions. The nozzle includes an orifice (36) at a proximal end thereof adjacent the body portion, as well as a pump (38) for moving liquid into an area of the nozzle just forward of the orifice. A mechanical system (12, 13, 14) is provided for moving a plunger or piston element (16) first away from the orifice under tension, such as a compression spring (24), and then controllably releasing the plunger or piston toward the orifice, the plunger/piston moving with sufficient force that atmospheric air which has been drawn into the appliance between the plunger or piston is forced through the orifice at a sufficiently high rate of speed to produce a spray of fluid droplets for dental cleaning when the moving air comes into contact with the liquid in the nozzle.

    摘要： An oral care appliance comprises: a fluid pump assembly (46); a source of liquid (50); and a source of gas (12), wherein the pump is in operative communication with the sources of liquid and gas to produce a series of gas-injected fluid pulses, directed to a nozzle assembly (80) from which the resulting pulses are directed to the teeth. The individual pulses have a pulse width in the range of 0.001-0.5 seconds, a pulse height from 0.1-10 Newtons, and a rise/fall time range of 0.5-250 ms, a repetition rate in the range of 2 Hz to 20 Hz. The gas/liquid mixture range from 40-95% volume to volume, gas to liquid.
