Description

电动牙刷及可置换部件
发明领域
本发明涉及在所述牙刷头部上利用一个电动元件的电动牙刷。在某些型式的牙刷中，牙刷头部的部件是可置换的。
发明背景
通常，本发明涉及一种具有设置在头部上的一个或多个电动元件(包括但不限于发光二极管、使用白炽元件的发光元件、激光元件、卤素元件、氖元件、荧光元件、等离子元件、氙元件、牙线洁齿元件、按摩元件、刮擦元件、发热元件、声波发射元件、超声发射元件、电流发射元件、物质发射元件和/或它们的任何组合)的口腔护理器具。此类口腔护理器具可包括但不限于电动牙刷、电动牙线、牙齿抛光器、牙龈按摩器等。一直以来，电动元件很昂贵，并且其寿命超过在牙刷头部上的刷毛的常规寿命。电动牙刷可具有可置换的头部，然而如果将电动元件设置在牙刷的头部上，置换头部也要置换电动元件。在牙刷头部上的刷毛和/或其它部件需要置换之时，电动元件可不需要置换，因此最理想的是置换牙刷头部上的刷毛和/或其它部件而不置换电动元件。然而，置换头部上的刷毛和/或其它部件而不置换电动元件要求刷毛和/或其它部件是可移除的和/或可置换的，而不会影响和/或损坏设置在牙刷头部上的电动元件。此外，各部件可为可移除的和/或可置换的，而不会切断电动元件和电池间的电连接。
因此，一种公认的消费者需要的是这样一种电动牙刷，其包括一个设置在具有可移除的和/或可置换的部件的牙刷头部上的电动元件，使消费者能够移除和/或置换部件而无需置换电动元件。
发明概述
本发明提供一种电动牙刷，所述电动牙刷包括：柄部、头部和在柄部与头部之间延伸的颈杆，柄部限定一个中空内部区域，所述电动牙刷具有一条纵向轴线；所述头部包括至少一个电动元件、一个被电气连接到所述电动元件上、设置在柄部所限定的中空内部区域中的马达和至少一个部件，其中所述部件可被移除和置换而无需从牙刷头部移除电动元件。

实施方案详述
一般而言，本发明涉及一种用于口腔的口腔护理器具，其具有设置在头部上的一个或多个电动元件，包括但不限于发光二极管、使用白炽元件的发光元件、激光元件、卤素元件、氖元件、荧光元件、等离子元件、氙元件、牙线洁齿元件、按摩元件、刮擦元件、发热元件、声波发射元件、超声发射元件、电流发射元件、成分发射元件和/或它们的任何组合。此类口腔护理器具可包括但不限于电动牙刷、电动牙线、牙齿抛光器、牙龈按摩器等。本文所用术语电动元件包括在设置所述元件的位置处可转换电能的任何电动元件。例如，一个发光元件可在设置元件的位置例如在电动牙刷的头部上将电能转换成光。为简化起见，下文中本发明将具体以具有在其上设置了一个发光元件的头部的电动牙刷进行讨论。然而，可设想本发明可为一种不包括刷毛的口腔护理器具。除了电动元件之外，依照本发明所制的电动牙刷还可包括一个或多个活动刷毛载体，可任选的一个或多个静止刷毛载体、传动轴、马达、诸如电池之类的电源，并可包括可移除的和/或可置换的其它弹性或非弹性部件。
本发明的电动牙刷可被用作个人卫生制度的部件采用马达驱动的运动来清洁其牙齿和牙龈，同时发光元件照亮刷擦的区域，包括牙齿和/或牙龈在内。此外，从该电动牙刷发射出的光可用来激活位于口腔中的物质的不同性质。本发明涉及一种电动牙刷，其具有可置换的和/或可移除的头部和/或颈杆部分，包括但不限于可移除的和/或可置换的前刷毛支承板、刷毛载体或诸如三聚氰胺-甲醛泡沫、牙线、刮齿器、牙龈按摩器、刮擦部件、抛光杯、橡皮剔牙器之类的其它部件和/或它们的任何组合。当部件被磨损时或消费者希望在牙刷头部上换上一个不同的部件时，具有这些可移除的和/或可置换的部件使使用者能够移除和/或置换牙刷的各种部件。
如图1和2所示，在本发明的一个实施方案中，电动牙刷10包括一个细长的主体部分或柄部12、一个头部16和一个在头部与柄部之间延伸的颈杆14。电动牙刷的这个实施方案包括一个活动刷毛载体20和抓握部分70和72。如图2所示，本发明的这个实施方案也包括一条纵向轴线19、静止刷毛载体22和一个设置在包括刷毛24的摆动式刷毛载体20的中心上的电动元件75。
刷毛载体是牙刷上设置刷毛的部件。刷毛载体可或是静止的或是活动的。静止刷毛载体未被可操作地连接到一个传动轴上。可供选择地，活动刷毛载体是可操作地连接到传动轴上的刷毛载体，其被连接到马达上。可将刷毛设置在刷毛载体上。本发明的电动牙刷提供的运动种类可变化很大。活动和/或静止刷毛载体和设置在其上的刷毛排列也可变化很大。例如，静止刷毛可部分地或全部地环绕活动刷毛载体，或可被设置在多个活动刷毛载体之间的缝隙中。适用于本发明的某些刷毛载体运动和刷毛排列的实施例被描述于US 20030126699、US20030084525、US 20030084524、US 20030084526以及WO 03/063723和WO03/063722中。刷毛可由传统的非弹性材料如聚乙烯制成，或可由弹性材料如天然或合成橡胶、聚烯烃、聚醚酰亚胺、聚酯、聚苯乙烯、聚氨酯等、或各材料的组合物制成。
如图3所示，柄部12还包括一个装有马达32的中空内部区域30。中空内部区域30大体上沿着一条轴线34延伸并装有马达32和一个或多个电源例如电池60。可利用开关元件或触头50和54连同开关52一起选择性地运行马达32和电动元件75。在该实施方案中，马达32通过一个可旋转的转轴44驱动活动刷毛载体20。转轴44绕着轴线19旋转或摆动。一个齿轮装置被可操作地互连在转轴44和马达32之间。齿轮装置包括一个蜗杆40和一对步进齿轮42、43。马达32被可操作地连接到蜗杆40上。步进齿轮42被可操作地连接到步进齿轮43和蜗杆40上。发光元件74被设置在刷头的内部。装设了一个开关52来控制电动牙刷的运行并将其可操作地连接到马达32上。也构型开关52来操作牙刷的一个或多个发光元件。此类操作可为瞬态的或连续的。当开关52被关闭时，在柄部12的中空内部区域30内部装设的电池60和马达32以及电动元件75之间的电路被接通。
当马达的某些动作导致活动刷毛载体的响应时，一个马达被可操作地连接到活动刷毛载体上了。不要求物理连接。转轴可从马达中伸出穿过颈杆并伸入至少一部分头部中。当被马达驱动时，转轴可旋转、摆动、直线往复运动、回转、振动或轨道运行以便赋予一种或多种运动给活动刷毛载体。可在马达和转轴之间或转轴和活动刷毛载体之间装设齿轮装置以便将运动赋予给活动刷毛载体。示例性的转轴和/或齿轮装置被显示于美国专利6,360,395和5,617,601与申请WO03/079358以及本文引用的其它专利和专利公布中。也可采用一个磁力传动器来将振动运动赋予给牙刷刷毛，如美国专利5,189,751中所公开的那样。振动的电动牙刷的其它实施例被显示于美国专利5,189,751、5,544,382和5,448,792中。
柄部也具有一个设置在其中用于给马达和发光元件提供动力的电源如一个或多个电池。可供选择地，可将电动牙刷连接到一个用于给马达和发光元件提供动力的外部电源上。
牙刷的可移除的和/或可置换的部件包括但不限于前刷毛支承板、刷毛载体或其它部件如三聚氰胺-甲醛泡沫、牙线、刮齿器、牙龈按摩器、刮擦部件、抛光杯、橡皮剔牙器，以及其它弹性或非弹性部件和/或它们的任何组合。本发明的可移除的和/或可置换的部件可扣合和/或滑动接合电动牙刷，使得它们可如期望的那样被移除和/或置换而无需置换也设置在牙刷头部上的电动元件。此外，这些部件可具有孔口、或半透明的和/或透明的部分，从而使设置在牙刷头部上的电动元件能够透过部件和/或从牙刷的头部发射。各部件可直接接合牙刷头部或可被设置在一个载体上。此外，在单个载体上可设置各部件的组合。
在一个实施方案中，电动牙刷的可移除的和/或可置换的部件为至少一个刷毛载体。刷毛载体可单独地扣合和/或滑入牙刷头部及卸下。本发明的电动牙刷可具有多个可移除的和/或可置换的刷毛载体，或单个可扣接和/或滑接头部的刷毛载体。活动和静止刷毛载体均可为可移除的。此外，活动刷毛载体可接合头部并可操作地连接到传动轴上。如图4-6所示，在具有一个往复运动的活动刷毛载体的一个实施方案中，牙刷的头部112安放一个活动刷毛载体100和一个静止刷毛载体102。活动刷毛载体100借助于滑槽120滑接牙刷头部。设置在活动刷毛载体100上的滑轨122被安放在置于牙刷头部112上的滑槽120中。当可操作地连接于传动轴130上之时，活动刷毛载体100往复运动。活动刷毛载体100通过与传动轴130内部的一个孔150相啮合的一个隆起140连接到传动轴130上。当活动刷毛载体滑接牙刷头部时，活动刷毛载体上的隆起可被安放在传动轴的孔口内，从而可操作地将活动刷毛载体连接到传动轴上。一个电动元件如发光元件175被设置在头部之内，使得活动刷毛载体在发光元件175的顶部之上滑动。活动刷毛载体100可还包括一个通过其电动元件可进行放射的孔口104或半透明和/或透明部分。牙刷头部112也可借助于滑槽120安放一个静止刷毛载体102。设置在静止刷毛载体102上的滑轨124被安放在置于牙刷头部112上的滑槽120之内。在该实施方案中，可移除的和/或可置换的部件为静止和活动刷毛载体。活动刷毛载体还包括可将刷毛置于其中的孔口180。此外，刷毛可被置于牙刷头部上的孔口170和静止刷毛载体上的孔口160中。在如图7至9所示的另一个实施方案中，活动刷毛载体摆动。在该实施方案200中，活动刷毛载体202扣合到牙刷的头部212上。刷毛载体还包括一个被安放在传动轴210的孔口206之内的隆起204，从而可操作地将活动刷毛载体202连接到传动轴210上。活动刷毛载体202也包括一个孔口216。当将活动刷毛载体装到牙刷头部212上时，发光元件275和这个孔口相配合并可将光线透过其，如图9所示。牙刷的这个实施方案也可包括一个如图8所示的静止刷毛载体218。该静止刷毛载体可扣合或滑接到牙刷头部上。在该实施方案中，静止刷毛载体包括一个装配进牙刷头部212上的孔口222中的隆起220。活动刷毛载体202还可包括刷毛224。静止刷毛载体218可包括置于孔口226中的刷毛。
在本发明的另一个实施方案中，可移除的和/或可置换的部件是牙刷的前刷毛支承板。前刷毛支承板是形成电动牙刷头部和颈杆部分的壳体的前半部分。壳体的前半部分可包括刷毛以及置于牙刷头部上的任何其它部件。可供选择地，壳体的后半部分包括电动元件和传动轴。在该实施方案中，前刷毛支承板扣合及拆离电动牙刷。这使刷毛和其它部件能够进行置换而无需置换电动元件。此外，这使牙刷头部敞开，其可使置换电动元件更容易，因为它允许接近电动元件。在这个实施方案300中，前刷毛支承板302然后可如图10至11所示接合牙刷300的壳体304的后半部分。在这个实施方案中，前刷毛支承板通过扣合接合壳体的后半部分。刷毛支承部分具有装配进设置在壳体的后半部分上的孔口308中的隆起306。也可设想壳体的后半部分可具有装配进设置在前刷毛支承板上的孔口中的隆起。然而，也可设想前刷毛支承板可借助于一个滑槽和滑轨配合滑入和滑出。
在另一个实施方案400中，牙刷头部包括单个刷毛载体，如图12所示。在该实施方案中，头部412的这个单个刷毛载体402是可移除的和/或可置换的。牙刷的这个部分可包括如图13所示被置于孔口408中的刷毛406。这个刷毛载体402可借助于一个扣合配合(包括隆起410和孔口416)接合牙刷头部。然而，也可设想刷毛载体可借助于一个滑槽和滑轨配合滑入和滑出。如图13所示，刷毛载体包括一个孔口420。当刷毛载体402接合牙刷头部412时，电动元件例如发光元件475被安放在孔口420内并可透过其发光。
牙刷头部可包括非刷毛的可移除的、可置换的部件，包括但不限于三聚氰胺-甲醛泡沫、牙线、刮齿器、弹性部件(具体地讲牙龈按摩器、刮擦部件、抛光杯、橡皮剔牙器)和非弹性部件和/或涂敷器，如图14至20所示。图14至18图示说明可被用作牙龈按摩器、刮擦部件、涂敷器和/或橡皮剔牙器的各种弹性元件。此外，图19图示说明一个可用于清牙垢的牙线，以及图20图示说明一个可用于抛光牙齿的抛光杯。牙线500包括可保持一片洁齿牙线501的元件502和504。这些部件可单独地与牙刷头部接合和/或可将部件设置在一个扣合和/或滑接到牙刷头部的载体上。这些部件与一个电动元件例如发光元件一起使用可获得附加的口腔护理有益效果。
在所有前述实施方案中，电动元件均通过导线被连接到电池上。这些导线在移除和/或置换可移除的和/或可置换的部件期间不被切断和/或拆下。如图21所示，牙刷的一个实施方案具有一个固定的电动元件75，其被连接到和/或设置在固定的接线柱91之内并在牙刷的点93处固定到头部95上。在该实施方案中，活动刷毛载体97绕着设置在接线柱91内部的固定电动元件75摆动或旋转。这个设置在接线柱91内部的电动元件75起牙刷头部95上的活动刷毛载体97的旋转轴线的作用。本发明的这个实施方案具有正极87和负极89，其从电动元件75通过接线柱91、并且然后沿着牙刷的头部95和颈杆(未示出)的长度而下流到电源(未示出)如电池。
在本发明的一个实施方案中，三聚氰胺泡沫被设置在牙刷头部上。当用来清洁牙齿时，三聚氰胺泡沫显示去污性。当三聚氰胺泡沫用合适的溶剂例如水进行润湿时，在牙齿接触润湿的三聚氰胺泡沫时，其从牙齿上除去色斑。湿泡沫也可有助于去除牙斑和牙垢。去除色斑、牙斑和牙垢不要求使用洗涤剂成分，真正的去除可发生在用纯净水润湿三聚氰胺泡沫之时。与牙齿“相接触”包括用三聚氰胺泡沫涂擦、撞击和/或摩擦牙齿。三聚氰胺泡沫能够去除色斑、牙斑和牙垢而不磨损牙齿的表面。可将一片三聚氰胺泡沫装在口腔护理器具的头部上用于清洁牙齿。这个片可横跨整个头部，或可仅仅覆盖口腔护理器具头部的一部分。具体地讲，可将一片泡沫设置在口腔护理器具的可置换的部件上，因此泡沫片可根据需要进行置换。三聚氰胺泡沫可被用于牙刷头部上并与刷毛和/或光结合来进一步增强从牙齿上清洁和/或去除色斑。也设想可将一片三聚氰胺泡沫装在一个手动牙刷或其它口腔清洁器具上，并不只限于用于电动牙刷上。此外，包括三聚氰胺泡沫的口腔护理器具并非必须具有电动元件、刷毛和/或其它清洁器具设置在头部，相反地，口腔护理器具的头部可只包括一片三聚氰胺泡沫。这个口腔护理器具可具有一个可置换的部件，其中三聚氰胺泡沫可在需要之时进行置换。在该实施方案600中，如图22所示，口腔护理器具包括一个头部612、一个颈杆614和一个柄部610。此外，口腔护理器具包括一片三聚氰胺泡沫620。这片泡沫可被设置在一个载体上，并扣合或滑接于牙刷头部，从而便于根据需要置换三聚氰胺泡沫。
也设想本发明的电动元件是可置换的。包括可移除的和/或可置换的部件的电动牙刷可帮助置换电动元件。可卸下电动牙刷的部件如前刷毛支承板，从而暴露电动元件使得它可被置换。在电动元件被置换之后，然后可在牙刷头部上置换部件。
将一个开关设置在柄部上用于启动马达和/或电动元件。电动牙刷的一个实施方案具有一个开关，其包括一个致动器按钮和一个金属触头。当在一个常规的瞬态开关中时，这个开关通过压一个模塑的致动器按钮向下压靠金属触点、接通电路而手动压下。当在一个常规的连续开关中时，通过按压和向前滑动致动器按钮，这个开关允许通过一个滑道设计连续操作。通过在一个开关中将这两种功能组合起来，顾客在购买之前可试用装置并观看其运行，并且在拿出包装之后仍可连续地运行它。开关也可启动一个或多个电动元件。优选地，无论什么时候启动马达，电动元件就通电。然而，牙刷可具有超过一个开关来启动电动元件和/或活动刷毛载体。
在一个依照本发明的实施方案中，一个刷头包括一个压敏开关，其在某物接触牙刷的刷毛或头部时启动电动元件。当一切断所述接触、或自动在某个规定的时间之后，一个依照这种设计的开关就可将电动元件关闭。可将电动元件定时以指示应当使用电动牙刷多长时间来刷牙，或牙齿或口腔组合物应当暴露于元件辐射下多长时间。例如，一旦刷毛接触牙齿，电动元件接通并保持约两分钟，并且电动元件自动地关闭。尽管前述的开关是所熟知的，可用其它开关来代替。
此外，可采用一种发光材料来形成牙刷的全部或一部分，包括牙刷头部和/或刷毛载体在内。此类材料的一个实施例为购自Nichia America Corporation的UltraGlow。
在上述每一个实施方案中，发光元件被置于活动和/或静止刷毛载体之中、之上、周围、之下或直接相邻，以便光被尽可能有效地对准刷洗区域。
各种各样的发光元件可供本发明之用。具体地讲，小型的、耗能低的发光元件、发光二极管(LED)例如那些加利福尼亚州San Jose的Lumileds Lighting，LLC生产的以名称LuxeonTM市售的元件。其它市售的优选发光装置包括购自AmericanOpto Plus LED Corporation的那些元件。
刷毛也可能被变色、着色、染色以大体上与发光元件发出的光的颜色匹配。这样，刷毛不会吸收，而是反射发光元件发出的光。此外，可利用帮助将光对准牙齿或牙龈表面的反射屏，其被放置在发光元件周围或附近。此外，牙刷的头部可用一种反射材料来成型和/或涂敷，使得光对准牙刷的发射点。
尽管柄部被叙述成优选地电池驱动的，本发明也包括其它所熟知的电源，例如具有一个用于外部连接的电线或充电电池以及相关的牙刷载体/充电器(未示出)。
可将电动牙刷包装成一个包括一个或多个可置换的和/或可移除的部件的套盒。具体地讲，可将电动牙刷与置换刷毛载体和/或前刷毛支承板一起进行包装。部件可分配给一个家庭的不同成员。因此，彩色特征通常是套盒中的不同部件的一部分。尽管柄部被叙述成电池驱动的，本发明也包括其它所熟知的电源例如外部连接的电线或充电电池以及相关的刷载体/充电器(未示出)。套盒还可包括一个或多个包装好的光激活口腔物质和/或组合物，例如包装好的牙齿增白组合物。此外，套盒可包括其它非光激活的口腔护理物质例如洁齿剂。
所有引用文献的相关部分均引入本文以供参考；任何文献的引用不可解释为对其作为本发明的现有技术的认可。
尽管已用具体实施方案来说明和描述了本发明，但对于本领域的技术人员显而易见的是，在不背离本发明的精神和保护范围的情况下可作出许多其它的变化和修改。因此，有意识地在附加的权利要求书中包括本发明范围内的所有这些变化和修改。
