使用脉冲流体流和机械动作的口腔护理器具
摘要：
一种口腔护理器具，包括：气体-液体清洁组件，该组件包括：流体泵组件(46)；液体的源(50)；和气体的源(12)。泵与液体和气体的源可操作的连通以产生被导向至喷嘴组件(80)的一系列注入有气体的流体脉冲，产生的脉冲通过用户被从喷嘴组件导向至牙齿。单个脉冲具有在0.001秒至0.5秒的范围内的脉冲宽度、从0.1牛顿至10牛顿的脉冲高度、0.5ms至250ms的范围的上升/下降时间、在2Hz至20Hz的范围内的重复率。气体/液体混合物的气体对液体的体积比是从40％至95％的范围。器具还包括与气体-液体组件组合的机械牙齿清洁组件。机械组件包括驱动系统(160)和与驱动系统可操作接触的刷子组件，刷子组件在其远端具有一组刷毛(152)，其中在操作中，喷嘴组件被定位在刷子组件内。
摘要（英）：

An oral care appliance comprises an gas-liquid cleaning assembly which comprises a fluid pump assembly (46); a source of liquid (50); and a source of gas(12). 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 by a user. The individual pulses have a pulse width within the range of 0.001-0.5 seconds, a pulse height from 0.1-10 Newtons, a rise/fall time range of 0.5-250 ms, a repetition rate in the range of 2Hz to 20Hz. The gas/liquid mixture range from 40-95% volume to volume, gas to liquid. The appliance also includes a mechanical teeth cleaning assembly, in combination with the gas-liquid assembly. The mechanical assembly 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.
