具体实施方式
下面结合示例详细描述本发明的优选实施例。本领域技术人员应理解的是，这些示例性实施例并不意味着对本发明形成任何限制。
图1是根据本发明第一优选实施例的牙刷的示意性立体图，图2是根据本发明第一优选实施例的牙刷的另一示意性立体图。如图1和2所示，根据本发明第一优选实施例的牙刷1包括牙刷柄3和可拆卸地安装到牙刷柄3上的牙刷头5。
图4是根据本发明第一优选实施例的牙刷的牙刷柄的示意性立体图，图5是根据本发明第一优选实施例的牙刷的牙刷柄的另一示意性立体图。如图4和5所示，牙刷柄3包括供使用者抓握的抓握部3a以及与抓握部3a相连的牙刷头安装部3b。尽管抓握部3a与牙刷头安装部3b可以分开地形成并且随后被组装在一起，抓握部3a与牙刷头安装部3b优选一体地形成。在牙刷头安装部3b上形成有穿透的第一孔7。尽管在优选实施例中，第一孔7被显示为四个，并且相对于牙刷柄的纵向轴线AA对称地分布，但应理解的是，第一孔7的数目可以少于四个，例如，三个、二个、甚至为一个，第一孔7的数目当然也可以多于四个，并且也根据实际需要采用其它分布方式。此外，尽管第一孔7被显示为穿透的通孔，但应理解的是第一孔也可以为盲孔。
在牙刷头安装部3b上还可以进一步形成有穿透的第二孔9。尽管在优选实施例中，第二孔9被显示为三个，并且沿着牙刷的纵向轴线AA分布，但应理解的是，第二孔9的数目可以少于三个，例如，二个、甚至为一个，第二孔9的数目当然也可以多于三个，并且也根据实际需要采用其它分布方式。
图6-11示意性地显示了根据本发明第一优选实施例的牙刷的牙刷头。如图6-11所示，根据本发明第一优选实施例的牙刷的牙刷头5包括牙刷头本体11、以及安装到牙刷头本体11的第一侧11a上的刷毛13。根据本发明，牙刷头5还包括形成在牙刷头本体11的与第一侧11a相反的第二侧11b上的突出插接部15。牙刷头5上的突出插接部15的数目和分布与牙刷柄3的牙刷头安装部3b上的第一孔7的数目和分布相对应，使得牙刷头5上的每个突出插接部15可以***接到牙刷柄3的牙刷头安装部3b上的相应第一孔7中。结果，牙刷头5能够被可靠地安装到牙刷柄3的牙刷头安装部3b上，如图1和2所示。
尽管可以通过在突出插接部15与第一孔7之间形成紧密配合使得牙刷头5被可靠地安装到牙刷柄3的牙刷头安装部3b上，但是为了便于牙刷头5更容易地安装到牙刷柄3以及从牙刷柄3上拆卸，如图3b所示，牙刷头5上的突出插接部15包括从牙刷头本体11延伸的根部15a以及与根部15a成一体但尺寸变大的端部15b，并且在突出插接部15中还形成有从端部15b延伸到牙刷头本体11的切除部15c。对应地，第一孔7包括与突出插接部15的根部15a对应的第一部分7a、以及与突出插接部15的端部15b对应并且比第一部分7a尺寸大的第二部分7b。突出插接部15的根部15a的径向尺寸选择成与第一孔7的第一部分7a的径向尺寸大体相同或者比第一孔7的第一部分7a的径向尺寸略小，突出插接部15的端部15b的径向尺寸选择成与第一孔7的第二部分7b的径向尺寸大体相同或者比第一孔7的第二部分7b的径向尺寸略小。牙刷头本体11以及突出插接部15和/或牙刷柄3通常是由塑胶材料注塑而成。在将突出插接部15插接到牙刷柄3的牙刷头安装部3b上的相应第一孔7中时，突出插接部15的端部15b与第一孔7的侧壁接触而受到挤压，切除部15c容许端部15b的两个部分相互靠近而径向尺寸变小以穿过第一孔7的第一部分7a。一旦突出插接部15的端部15b穿过第一孔7的第一部分7a，突出插接部15的端部15b就进入到第一孔7的第二部分7b中并且恢复到其原始尺寸，这样，就可以将牙刷头5与 牙刷柄3可靠地锁定在一起，如图3a所示。尽管在优选实施例中，切除部15c被显示为一个贯穿突出插接部15的侧壁的横切口，切除部15c也可以形成为十字形、花瓣形、中空形、或在受到挤压时能够使突出插接部15的端部15b的径向尺寸变小的其它任何合适形状。
为了在将牙刷头5安装到牙刷柄3上时牙刷头5上的突出插接部15与牙刷头安装部3b上的相应第一孔7易于对齐，牙刷柄3的牙刷头安装部3b的周边形成有凸缘3c，以限定用于容纳牙刷头本体11的凹形空间3d。凹形空间3d的尺寸与牙刷头本体11的尺寸大体上相对应，这样，当牙刷头本体11被安置在凹形空间3d中时，牙刷头5上的突出插接部15正好对准牙刷头安装部3b上的相应第一孔7。此外，凹形空间3d的尺寸与牙刷头本体11的尺寸大体上相对应还使得牙刷头安装部3b与牙刷头本体11之间的缝隙尽可能地小，以尽可能防止或减少污物或者水分被夹在牙刷头安装部3b与牙刷头本体11之间。
图6-11还详细显示了根据本发明第一优选实施例的牙刷头5上的刷毛13的分别。刷毛13大体可以分为三组，即布置在牙刷头本体11中心位置的第一组刷毛13a、以及沿着牙刷头本体11的纵向对称地布置在第一组刷毛两侧的第二组刷毛13b和第三组刷毛13c。每组刷毛包括由多根刷毛组合在一起的多个刷毛簇。第一组刷毛13a中的刷毛簇沿着牙刷头本体11的纵向成多个直线列并且相互间隔开地布置，在优选实施例中显示为四个列，但应理解的是可以呈少于或多于四个列的形式布置。第一组刷毛13a中的每个刷毛簇还大体上与经过牙刷头本体11的纵向轴线BB并且和牙刷头本体11的第一侧11a大体垂直的平面P平行地设置。第二组刷毛13b和第三组刷毛13c中的刷毛簇沿着牙刷头本体11的纵向成多个直线列并且相互间隔开地布置，在优选实施例中显示各为二个列，但应理解的是可以呈少于或多于二个列的形式布置。第二组刷毛13b和第三组刷毛13c中的每个刷毛簇还大体上相对于平面P向外侧倾斜地设置，使得在沿着平面P远离牙刷头本体11的方向第二组刷毛13b和第三组刷毛13c与第一组刷毛13a之 间的间隙逐渐增大，如图9所示。尽管在优选实施例中，第二组刷毛13b和第三组刷毛13c中远离第一组刷毛13a的一列刷毛簇比靠近第一组刷毛13a的一列刷毛簇以更大角度地向外倾斜，第二组刷毛13b和第三组刷毛13c中远离第一组刷毛13a的一列刷毛簇与靠近第一组刷毛13a的一列刷毛簇以相同角度向外倾斜也是可行的。这种刷毛的布置方式使得在刷牙时第一组刷毛13a可以更深入地进入牙缝以去除牙缝之间的残渣，以提高对牙齿的清洁效果，同时第二组刷毛13b和第三组刷毛13c可以对牙龈起到按摩作用。更优选地，当从牙刷头5的端侧观察时，第一组刷毛13a、第二组刷毛13b和第三组刷毛13c中的刷毛簇远离牙刷头本体11的末端大***于凹弧形面C上，以使得刷毛更好地贴合牙齿和牙龈，以进一步提高清洁和按摩效果。
图12-18显示了根据本发明第二优选实施例的牙刷。图12-18所示第二优选实施例的牙刷与图1-11所示第一优选实施例的牙刷大体上相同，除了刷毛的设置略有不同之外。为了简化起见，以下只描述第二优选实施例与第一优选实施例的不同之处，而省略其它部分的详细描述。
如图12-18所示，根据本发明第一优选实施例的牙刷头5除了第一组刷毛13a、第二组刷毛13b和第三组刷毛13c之外，还包括布置在牙刷头本体11远离牙刷柄3一端的第四组刷毛13d。在优选实施例中，第四组刷毛13d包括两列呈弧形布置的刷毛簇，但可以理解的是可以设置一列或者更多列呈弧形布置的刷毛簇。更优选的是，第四组刷毛13d中的每个刷毛簇相对于弧形的中心向外倾斜地设置。通过设置第四组刷毛13d，可以进一步提高对牙齿的清洁和对牙龈的按摩效果。
尽管可以借助于直接穿过牙刷柄上的第二孔9的工具使牙刷头与牙刷柄分离，本发明还是提出了专门用于安装和拆卸牙刷头的装置20。如图19-27所示，用于安装和拆卸牙刷头的装置20包括下部壳体21和可枢转地安装到下部壳体21上的上部壳体23。上部壳体23相对于下部壳体21枢转以打开或者关闭用于安装和拆卸牙刷头的装置20。用于安装和拆卸牙刷头 的装置20还包括安装到下部壳体21上的内衬部件25，内衬部件25上形成有牙刷头安装腔27，牙刷头安装腔27用于容纳待安装的牙刷头5，但是在牙刷头安装腔27的内壁上形成有台阶部27a。在优选实施例中，台阶部27a形成在牙刷头安装腔27的纵向两端，但应理解的是，台阶部27a形成在牙刷头安装腔27的纵向两侧也是可行的。如图29所示，当牙刷头5被放置在牙刷头安装腔27中时，牙刷头5的牙刷头本体11的边缘部分被支撑在台阶部27a上，从而将牙刷头5在牙刷头安装腔27中保持在位。优选地，内衬部件25上还可以形成有与牙刷头安装腔27连通并且用于容纳牙刷柄3的一部分的第一凹槽29。
内衬部件25上还形成有牙刷头拆卸腔31，牙刷头拆卸腔31用于容纳已安装在牙刷柄上的牙刷头以及牙刷柄的一部分。牙刷头拆卸腔31的内壁上也形成有台阶部31a。在优选实施例中，台阶部31a形成在牙刷头拆卸腔31的纵向两端，但应理解的是，台阶部31a形成在牙刷头拆卸腔31的纵向两侧也是可行的。如图34所示，当安装在牙刷柄上的牙刷头5被放置在牙刷头拆卸腔31中时，牙刷柄3被支撑在台阶部31a上但牙刷头5的牙刷头本体11位于台阶部31a内侧，从而将安装在牙刷柄上的牙刷头5在牙刷头拆卸腔31中保持在位。优选地，内衬部件25上还可以形成有与牙刷头拆卸腔31连通并且用于容纳牙刷柄3的一部分的第二凹槽33。
内衬部件25上还可以形成有清洁刷容纳腔35，以用于容纳清洁刷37。清洁刷37可以用于对牙刷进行清洁，尤其是用于去除可能夹在牙刷头5与牙刷柄3之间的污物。在优选实施例中，清洁刷容纳腔35形成在牙刷头安装腔27与牙刷头拆卸腔31之间，但应理解的是，清洁刷容纳腔35可以形成在其它位置，例如形成在牙刷头安装腔27和牙刷头拆卸腔31的端侧，如图38所示。
内衬部件25上还可以形成有用于容纳备用的牙刷头5的牙刷头容纳腔39。牙刷头容纳腔39的底壁上可以形成有与牙刷头本体11上的突出插接部15对应的通孔41，以用于容纳牙刷头本体11上的突出插接部15，从而 使得备用的牙刷头5被安稳地放置在牙刷头容纳腔39中。在优选实施例中，具有两个牙刷头容纳腔39并且分别被布置在牙刷头安装腔27和牙刷头拆卸腔31的两侧，但应理解的是，牙刷头容纳腔39的数目可以多于或少于两个，并且可以被布置在其它位置。
下部壳体21上形成有带中心腔43的凸柱45以及带卡接部47的突出部49。内衬部件25的底侧相应地形成有定位柱51以及带开口53的突出部55。通过将内衬部件25的底侧上的定位柱51***下部壳体21上的凸柱45的中心腔43中，可以使内衬部件25相对于下部壳体21快速地定位。通过进一步地向下按压内衬部件25，可以使下部壳体21上的突出部49的卡接部47被接收在内衬部件25的底侧上的突出部55的开口53中，从而将内衬部件25可靠地安装到下部壳体21上，如图27所示。应理解的是，内衬部件25还可以其它方式安装到下部壳体21上。此外，尽管在优选实施例中，内衬部件25与下部壳体21分开地形成，但是内衬部件25与下部壳体21一体地形成也是可行的。
在上部壳体23朝向下部壳体21或内衬部件25的表面上与牙刷头安装腔27对应的位置形成有突出的按压部57。在优选实施例中，按压部57被形成为空心格状，但它也可以为其它形状，只要能够通过它对牙刷柄施加压力。在上部壳体23朝向下部壳体21或内衬部件25的表面上与牙刷头拆卸腔31对应的位置形成有突出的推压柱59，推压柱59与牙刷柄3上的第二孔9的数目和位置相对应，并且能够自由地穿过第二孔9。此外，在下部壳体21和上部壳体23上还形成有锁定装置，例如形成在下部壳体21上的凸起61以及形成在上部壳体23上用于接收凸起61的凹口，以便在用于安装和拆卸牙刷头的装置20不使用时将下部壳体21和上部壳体23可靠地锁合在一起。用于安装和拆卸牙刷头的装置20的各个部件大体上可以由塑性材料注塑而成。
图28-32是显示利用用于安装和拆卸牙刷头的装置20安装牙刷头5的示意图。以下将结合图28-32描述利用用于安装和拆卸牙刷头的装置20安 装牙刷头的过程。首先，使上部壳体23相对于下部壳体21枢转以打开用于安装和拆卸牙刷头的装置20，接着将牙刷头5放置在牙刷头安装腔27中使得牙刷头本体11上的突出插接部15朝向上侧，如图28所示。接着，将牙刷柄3放置在牙刷头5上，使得牙刷柄3的牙刷头安装部3b上的第一孔7与牙刷头5上的突出插接部15对准，如图29所示。随后，将上部壳体23枢转到与下部壳体21闭合的位置，如图30所示。接着，向下按压上部壳体23，使得上部壳体23上的按压部57接触牙刷柄3的牙刷头安装部3b并且给牙刷柄3的牙刷头安装部3b施加向下的作用力。由于牙刷头本体11被支撑在牙刷头安装腔27的台阶部27a上，因此，牙刷头5上的突出插接部15穿过牙刷头安装部3b上的第一孔7，从而将牙刷头5安装到牙刷柄3上，如图31所示。最后，使上部壳体23相对于下部壳体21再次枢转以打开用于安装和拆卸牙刷头的装置20，取出已经组装好的牙刷1就可以使用了，如图32所示。
图33-38是显示利用用于安装和拆卸牙刷头的装置20拆卸牙刷头5的示意图。以下将结合图33-38描述利用用于安装和拆卸牙刷头的装置20拆卸牙刷头的过程。首先，使上部壳体23相对于下部壳体21枢转以打开用于安装和拆卸牙刷头的装置20，接着将装在牙刷柄3上的牙刷头5放置在牙刷头拆卸腔31中使得牙刷柄3朝向上侧，如图33和34所示。接着，将上部壳体23枢转到与下部壳体21闭合的位置，如图35所示。接着，向下按压上部壳体23，使得上部壳体23上的推压柱59穿过牙刷头安装部3b上的第二孔9，接触牙刷头本体11并且给牙刷头本体11施加向下的作用力。由于牙刷柄3被支撑在牙刷头拆卸腔31的台阶部31a上，因此，上部壳体23上的推压柱59使得牙刷头5上的突出插接部15从牙刷头安装部3b上的第一孔7中脱离出来，从而将牙刷头5从牙刷柄3上拆卸下来，如图36所示。最后，使上部壳体23相对于下部壳体21再次枢转以打开用于安装和拆卸牙刷头的装置20，取出已经分离开的牙刷柄3和牙刷头5，如图37所示。
图38是图19-27所示用于安装和拆卸牙刷头的装置的变体。如上所述，图38所示用于安装和拆卸牙刷头的装置与结合图19-27描述的用于安装和拆卸牙刷头的装置的区别仅在于：清洁刷容纳腔35形成在牙刷头安装腔27和牙刷头拆卸腔31的端侧。
图39是图19-27所示用于安装和拆卸牙刷头的装置的另一变体。图39所示用于安装和拆卸牙刷头的装置与结合图19-27描述的用于安装和拆卸牙刷头的装置的区别仅在于：它不包括用于容纳备用的牙刷头的牙刷头容纳腔。
图40是图19-27所示用于安装和拆卸牙刷头的装置的又一变体。图39所示用于安装和拆卸牙刷头的装置与结合图19-27描述的用于安装和拆卸牙刷头的装置的区别仅在于：清洁刷容纳腔35形成在牙刷头安装腔27和牙刷头拆卸腔31的端侧，并且它不包括用于容纳备用的牙刷头的牙刷头容纳腔。
此外，应理解的是，牙刷头容纳腔中存放的备用的牙刷头的刷毛排列不局限于优选实施例中所显示的排列方式。
利用本发明的用于安装和拆卸牙刷头的装置来安装和拆卸牙刷头使得牙刷头的安装和拆卸能够省力、简便、高效地进行。
尽管已经结合本发明优选实施例对本发明进行了详细描述，但应当理解的是，这种详细描述仅是用于解释本发明而不构成对本发明的限制。例如，突出插接部可以形成在牙刷柄上，而在牙刷头本体上形成用于接收突出插接部的孔。用于安装和拆卸牙刷头的装置可以没有牙刷头安装腔和对应的按压部或者没有牙刷头拆卸腔和对应的推压柱，这样，它就只具有安装和拆卸中的一种功能。总之，本发明的范围由权利要求限定的技术方案来确定。
