Abstract
一种牙刷,它有一个柄部(1)和一个载有硬毛的居前的头部(3),它们通过一个颈部(4)而彼此相连。在头部(3)中或者在与头部(3)相毗连的部位中安置了一个可使头部(3)振动的机械振动装置(10),该振动装置经过在颈部(4)中延伸的电连接线(33,34)而与安装在柄部(1)中的电源(25)有效相连。为了防止振动传递到柄部(1)上,配置了减振机构(7)。因此,振动首先在头部(3)中发生,而在柄部(1)上只能极微弱地感觉到,所以对牙刷的操作是舒适的。这种牙刷在其大小上大致相当于传统的手动牙刷,但是,使用这种简单而成本合算的牙刷仍可达到可与已知的、通常大得多又贵得多的电动牙刷相比的洁齿效果。
Description
本发明涉及如权利要求1的前序部分所述的一种牙刷。
为了牙齿清洁,当今或者使用传统的手动牙刷,或者使用电动牙刷,电动牙刷有一个活动的牙刷头部,从手柄以后可电动驱动。通常,用电动牙刷比用手动手刷能达到更强的清洁作用,当然,电动牙刷也有它们的缺点,就是它们的体积比较大,而且比较贵,还可能损伤牙龈,并引起强烈的牙痛磨损。
本发明的任务是提供一种便宜的牙刷,其大小大致与传统的牙刷相当,而比起传统的牙刷,能起到更好的洁齿作用。
上述任务根据本发明是通过一种具有权利要求1所述特征的牙刷来解决的。
在牙刷的居前的头部或者在一个将牙刷头部同牙刷柄部连接起来的颈部的一个与头部毗连的区域中,设置了一个可使牙刷头部处于振荡中的机械振动装置,该振动装置经过一些在颈部中延伸的电连线与一个被安装在柄部中的电源有效地连接起来,其中,为了防止振动传递到柄部上优选地配置了一些减振机构,由于以上的措施而达到了下述目的:能导致改善洁齿作用的振动首先在牙刷头部上施展,而在牙刷柄上只能轻微地感觉到,从而实现对牙刷的舒适操作。根据本发明的牙刷的另一个优点在于:由于柔性的牙刷颈部之故,不必对振动装置引入机械的驱动机构。通过颈部延伸的只有作为导线、电缆或导电的塑料线路设计的电连接线。
根据本发明提出的牙刷的优选的优选设计方案构成各项从属权利要求的主题。
下面将参照附图对本发明做更详细的说明。
附图示意地表示:
图1以侧视图和局部剖面图表示根据本发明提出的一种牙刷的第一个实施例和一个相互分离的牙刷柄-封闭件(无电池);
图2以仰视图和局部剖面图表示根据本发明提出的一种牙刷的第二个实施例,处于组合状态;
图3以侧视图和局部剖面图表示图2所示的牙刷和相互分离的封闭件(无电池);
图4以侧视图表示本发明提出的一种牙刷的第三个实施例,处于组合状态,
图5是根据图4所示牙刷的一个前部,带有可更换的操作头部的不同实施形式。
图1中所示的牙刷和图2与图3所示的牙刷都各自具有一个柄部1、一个居前的载有硬毛的头部3以及一个将头部3同柄部1连接起来的颈部4。组合成硬毛束6的硬毛被固定到一个硬毛载体5中,并以其自由端形成一个也许具有一定轮廓的牙刷面。按所示的结构形式,带有硬毛束6的硬毛载体5按照一种已知的因而无需详述的方式可以替换地装配到头部3的一个夹持部2上。
颈部4配有用一种有弹性的、较柔软的材料成份做成的颈部区7,这些颈部区能使得颈部4具有弹性,或者附带地提高其弹性,从而在使用牙刷时,载有硬毛的头部3在多种力的作用条件下可朝着牙刷面有弹性地后挤。必要时,颈部区7设计成经过颈部周边的一部分而延伸的、用一种挠性材料(例如用热塑性弹性体)填充的凹口设计成形的。当然,颈部区的其它形状和数量是可以完全设想的。一个柔性的颈部区在不使用弹性材料成份的条件下也是可想象的,例如通过收缩作用或者通过一种气囊。
在居前的头部3上,或者在与头部3相毗连的颈部4的部位上,集成一个机械式振动装置10,利用该振动装置便可将促进或增强洁齿作用的振动施加给载有硬毛的头部3。振动装置10经过在颈部4中延伸的电连接线可与一个安装在柄部1中的电源相连,如在下面所描述的,于此,上文已提及的用一种弹性柔软的材料做成的颈部区7用作减缓振动的头部3和柄部1之间动的手段,从而使振动作用主要在头部上发生,只是很微弱地传递到柄部1上。这一点意味着:在洁齿过程中,仅感觉到柄部1上有微弱的振动,因而使用这种牙刷是令人舒适的。即使反过来说也是个优点,就是所产生的振动不通过手柄1减振,而是可以完全在头部3上发挥作用。当然也可设想出其它减振手段以代替用弹性柔软的材料做成的颈部区7;不一定非用一种有弹性的材料不可。也可以在使用一种基本材料的条件下,通过颈部的特殊形状结构,例如通过布置一个气囊/手风琴式部分等来达到减振的目的。
在柄部1上设置了一个沿其纵向延伸的用导电材料做成的壳或套20。柄部1和套20都朝下开口,从而形成一个可通过封闭件22从后面封闭的空腔21,在该空腔中可装入一节电池25,在所示的实施例中,这种电池是一种市售的不能重复充电的棒形电池,其额定功率例如为1.5V,将其用作为振动装置10的能源。当然,作为能源,也可使用一种按钮式电池或一种可重复充电的蓄电池。
在套20中,在一个横壁28上安置了一个弹簧触头29,用于电池25的正极30(参看图2),它经过一根导电线31、一个安装安放在套20中并可从柄部1的外侧操纵的开关32和一个在颈部4中延伸的导电线33,连接到振动装置10上。利用开关32可切断电连接。
封闭件22配有一个用导电材料做成的螺纹榫头22a,利用该榫头可将封闭件拧入到柄部1中或套20中。螺纹榫头22a配有一个接触面22b,在拧入封锁部22时该接触面便可贴靠在套20中所装电池25的负极35上。负极35同振动装置10的电连通是这样实现的:经过螺纹榫头22a、套20本身和一条将套20连接到振装置10上的在颈部4中延伸的导线34。
代替经过导电的套20的办法,也可用别的办法来实现电流传导,例如使用金属线或一种可导电的塑料。
按图1中所示的实施例,振动装置10包含一个最好按一种振动枢方式发挥功能的振动元件11′,该振动元件可以经过导线33、34直接与电源实现电连接,在连接上电源时即可被置于振动之中。
按图2和3中所示的牙刷变型,振动装置10包括一个振动元件11,该振动元件具有的形式是一个能产生机械振动的、可围绕一个处于牙刷纵轴线方向中的轴旋转的偏心轮,还包括一个直接毗连地安置的作为微型电动机15设计的驱动装置。振动元件11与可以经过导线33、34而同电源实现电连接的微型电动机15的轴15a相连接。微型电动机15和偏心轮可以作为一个结构单元安放在一外壳12中。
代替可转动地驱动的偏心轮,也可考虑使用一个可移动地驱动的振动元件11。
看来也有可能在本发明提出的牙刷上相对于颈部4活动地安置载有硬毛的头部3,以便在利用振动装置10产生振动的情况下,将颈部置于相对牙刷的其余部分而言的一种运动中。
电导线31、33、34也可以用导电的塑料条带加以实现。
对于的能接通或切断导线31、33、34的电源的开关32,例如也可以指的是一种磁开关。
开关32的优选的结构当然包含一个布置在一印刷电路板上的脉冲开关及其存储开关工作状态的其它电子元件。
但电池25和振动元件11′(图1)或驱动装置15(图2和3)之间的电连接,也可以不通过开关32,而通过可拧入柄部1或套20的或可与之插接式相连的封闭件22的旋转来实现或切断(这就是说,按这种结构免去了开关32)。
代替居后的封闭件22同柄部1的螺纹连接方式,当然也有别的可松卸的连接方式(例如插头连接,插接式连接,等等),而且与负极35协同作用的接触部的一种相应设计方案也是可能的。
封闭件22也可以具有与附图中所示的形式完全不同的另一种形式。例如封闭件可以设计得具有一个放置面或一个脚部,借以用作为放置牙刷的一个元件。
图4中所示的牙刷基本上相当于图2和3所示的牙刷;其相同的部分都以相同的数字代号标出。按图4,振动装置10直接装在居前的头部3中。根据这一实施例取消了套20;电池25是直接经过导线33、34而与振动装置10相连的。即使在这种牙刷上最好也使用一种可以套接在头部3的夹持部2上的(例如用一种卡连方式)、可以更换的硬毛载体5。配备了硬毛束6的硬毛载体5的可更换性是特别有利的优点,这是因为所用的装配有振动装置10的牙刷与硬毛的寿命无关,通常硬毛的寿命比所用电池25的寿命甚至较短。
从图5可以看出,在这里,代替形成常规牙刷头部的一部分并配有硬毛事6或6a的硬毛载体5或5a,也可以有选择地将不同的其它硬毛载体或适配体5b至5d安置在夹持部2上,它们都配有不同的刷牙齿缝用的牙刷6b、6c或刷牙齿缝用的操作部分6d,以用于有效清洁牙缝。刷牙齿缝用牙刷6b例如可以设计成一种螺旋线形牙刷,它是用以旋入的塑料丝涂膜线做成的。刷牙缝用的牙刷6c是用共同形成一个束尖的硬毛做成的。操作部6d例如可以设计成为一个具有一尖峰的塑料元件,它最好可配有一个有刮磨作用的层,以之用于清除牙缝中的牙石和牙垢。当然也可以采用其它任意的操作头部。
按图4和5所示的变型,硬毛载体5也可以如此设计,使得相对于夹持部2的一种由振动所限定的运动成为可能。
为了引入振动装置10、连接导线33、34及其它电元件,本发明提出的牙刷及其外壳可分成两部分制造出来,这两个部分在置入上述的各部分之后加以焊封,以达到不透水的目的。
本发明提出的牙刷也可优先采用两部分或多重部分注塑法制造。其优点在于:前面述及的各部分可以作为一个单元嵌入到一个由第一材料部分注塑而成的型件中,然后以第二材料部分(或以其它材料部分)进行外部喷注。这里指的不必是全面的外部喷注。某些部分仍可以留着不喷注,从而可获得美观效果。
当然上面述及的电元件也可以嵌装到一个已注塑好的柄部1中。
由于不仅是振动元件11、11′本身而且还有驱动装置即微型电动机15都安置在居前的头部3中或安装在与颈部4的直接毗连的前面的部件,所以不必要将用于与振动元件11连接的微型电动机的机械驱动机构引导通过弹性的颈部4。只有电导线33、34(电线、电缆或可导电的塑料线路)延伸通过颈部4。
根据本发明,使用了一种机械振动装置10,它的直径小于15mm,最好小于6mm;其长度小于3 5mm,最好小于20mm。这样就可保证:牙刷可按人体工程学要求设计成形,而且便于操作。本发明提出的牙刷在其大小上大致与的手动牙刷相当,这一点意味着与市售的大得多的电动牙刷相比,操作更简单了,还有一点,使用这种牙刷可达到一种能与已知电动牙刷相比的甚至胜过它们的洁齿效果。此外,本发明提出的牙刷,制造简单,成本合算。
本发明提出的振动装置当然也可以与传统的电动牙刷相结合。
