Description

具有调制驱动信号的电动牙刷
技术领域
本发明通常涉及具有在声波频率范围的驱动信号的电动牙刷装置，并且更具体地说涉及所述驱动信号在频率或占空比上变化的这样的应用。
背景技术
许多电动牙刷包括多个刷牙模式或例行程序。通常，这些模式聚焦在各种牙科护理需求类型，例如经常或者温柔的刷牙、口腔按摩以及牙龈护理/刺激、等等。在早上和晚上都使用电动牙刷进行口腔护理。这样的口腔护理也经常是更详细的个人例行程序的一部分，其在晚上引起入睡并且在早上引起醒来。大家不只是对于在这些时间改进口腔护理感兴趣，而且对于在入睡之前减少不安以及在醒来后在开始日常活动之前变得思维敏捷感兴趣。
因此，理想的是电动牙刷具有影响使用者的注意力以及提供精神/认知刺激和/或精神/认知放松的能力。
附图说明
图1A-图1D是电动牙刷刷头的几个刷牙动作的简化视图。
图2A-图2C示出用于提供认知刺激信号和协助唤醒的驱动信号的调制示图。
图3A-图3C示出用于产生精神放松信号和协助入睡的驱动信号的调制示图。
图4是用于产生图2A和图3A的调制驱动信号的一个实施例的部分框图。
图5是用于产生图2A和图3A的调制驱动信号的第二个实施例的部分框图。
发明内容
相应地，电动牙刷，包括：手柄部分；刷头组件，在刷头组件的远端具有刷毛组；用于移动该刷毛组的驱动***，具有在声波范围的频率和能够产生临床上有效清洁使用者牙齿的范围的振幅的动作；以及调制***，用于改变所述驱动信号的频率和/或占空比，从而产生除了临床上有效牙齿清洁之外的认知效果。
具体实施方式
图1A-图1D示出产生各种刷毛动作的电动牙刷的简化形式。图1A示出电动牙刷10，该电动牙刷10具有手柄12和安装在颈部15的远端上的刷头14，其能够在特定的频率旋转特定的角度。刷头由包括在手柄部分12中的驱动***16驱动。图1A所示的刷牙为沿着装置的纵向轴从一边到另一边的旋转。图1B显示了另一个刷牙动作，其中刷头22沿着轴向的进出方向移动，沿着牙齿产生来回动作。图1C是从手柄28延伸的颈部(不可见)上的刷头26的端视图，其中所述刷毛以扫掠型动作移动。图1D是安装在从手柄32延伸的颈部(不可见)上的刷头30的端视图，所述刷毛以敲击型动作移动，垂直于装置的纵向轴，朝向以及远离牙齿。这样的单一运动能够通过各种驱动***来实现。用于扫掠动作的一个示例在美国专利号5,378,153中公开，其内容通过引用并入本文。通常，为了有效清洁，所述电动牙刷在声波频率范围内操作，在130-150Hz范围，但是也能在40和500Hz之间的更宽的频率范围操作。所述刷毛尖端的移动振幅通常在0.5mm和6.6mm之间，优选振幅约为3.5mm。更进一步，刷毛尖端的速度大于1.5米每秒，在1.5和2.0米每秒之间。
在本发明中，用于电动牙刷的驱动信号被调制为具有认知刺激或认知放松效果中的任一个。图2A和图2B示出用于产生认知刺激的驱动信号的调制的方面，具有在2A中34示出的调制周期(1/调制频率)，而图2B是频率框图，其用于示出由于图2A的调制，在刷头移动频率上的增加。在两分钟刷牙事件期间，所述调制在频率上增加。改变的范围从0.2Hz到100Hz。在一个特定实施例中，在典型的使用周期期间，调制频率每30秒会增加。作为一个示例，在第一周期，调制频率为0.5Hz；在第二周期，调制频率为0.75Hz；在第三周期，调制频率为1.5Hz；以及在第四周期，调制频率为3Hz。图2C显示每30秒在频率上的增加结果，参照35A、35B、35C和35D，其为使用者在强度上能够察觉的增长，产生认知刺激并且在觉醒(即唤醒类型调制)上的增长。
能够使用与上述类似的其它调制模式。更进一步，能够使用更加复杂的调制模式，包括在超过两分钟的刷牙事件中或者在每个刷牙事件的部分期间、或者在30秒间隔或者在其它时间中的任一个中的可变的音调。上述能够包括可变的音调、节律、或其它可听到的声音。如上所述，这样的模式将会导致在四个周期中在功率上的可觉察的增长。通常，为了认知刺激，在整个刷牙事件中在频率上调制频率会增加，尽管该频率在任一个特殊周期期间会在一定程度上改变。
图3A-图3C图示用于产生认知放松的驱动信号的调制模式。在该情况下，参见图3A，调制周期将会以相对低的值开始刷牙事件，调制频率位于比刷牙事件结束时更高的值，具有100Hz的高值到0.2Hz的低值。在两分钟刷牙时间中的特定时间，例如每30秒，所述调制频率会减少，会在刷头的声波有效频率中产生如图3B所示的改变。一个特定的实施例是第一个30秒的初始调制频率为3Hz；调制频率在第二个30秒周期为1.5Hz；调制频率在第三个30秒周期为0.75Hz；以及调制频率在第四个30秒周期为0.5Hz。在所述四个周期中的这些特定频率能够改变；调制频率在每个30秒周期中也能够改变；单个的周期时间也可以改变。但是，在刷牙事件的开始和刷牙事件的结束之间在调制频率上整体的效果应当是减少的。这导致在刷牙事件的开始或结束之间可察觉的功率强度减少，如图3C中37A-37D所示。这导致认知放松效果，因为将会有助于入睡。
图4以简化视图中示出用于产生如上所述的调制驱动信号的一个***。图4示出驱动信号源60，设计成产生临床上有效刷牙效果，以及调制信号源62。此外，调制信号62能够是在图2A和3A中示出的特定情况，或者也能够是某些其他的调制信号。通常，如上所述，调制信号一般跟随增加的频率模式来产生认知刺激或者一般减少频率模式来产生认知放松。来自于源62的调制信号以及来自于源60的驱动信号被施加给音频混频器64，其在施加给放大器69之后，产生用于驱动***66的调制信号。因此而产生的信号会驱动刷头68用于各种单一运动的实施例，诸如在图1A和图1D中所示，取决于使用的特殊驱动***。该信号被放大以至少1.5米/秒的速度产生0.5mm和6mm之间的刷头振幅。
图5示出备选的实施例，其中组合的驱动信号的数字记录如70所示。所述数字记录包括具有有效声频的强信号，诸如在40Hz到500Hz，组合有其它的可变的声调、节奏或声音。所述组合驱动信号接着被施加给放大器72以及接着被施加给驱动***74，其依次以单一运动来驱动刷头76，如图1A-图1D所示。所述组合驱动信号被放大以达到在0.5mm和6.6mm之间的理想的刷毛尖端振幅，伴随着刷毛尖端1.5米每秒的速度。
当上述调制改变驱动信号的频率的时侯，所述调制也能够类似地被用来改变驱动信号的占空比。
因此，已经描述了新的电动牙刷，其包括用于电动牙刷的产生单一刷头运动的驱动信号，其被调制为改变所述驱动信号的频率或占空比以产生认知刺激效果或者认知放松效果中。
尽管已描述的本发明的优选实施例是用于说明的目的，但是应当理解，在不脱离由下面的权利要求限定的本发明精神的情况下，各种改变、修改以及替换都可以结合到该实施例中。
