Abstract

一种牙线器，包括用于抓握的手柄(30)、用于清洁牙齿的牙线段(11)、以及用于固定和支撑牙线段(11)的支架(20)；牙线器的手柄(30)包括第一抓握部件(31)、第二抓握部件(32)以及铰链(33)。使用者操作牙线器的手柄(30)，能够让设置在其上的、变得松弛的牙线段(11)恢复到绷紧状态。

Description

牙线器 技术领域
本发明涉及一种用于清洁牙齿的口腔护理用品，特别涉及一种牙线器。使用者操纵该牙线器，对牙缝两侧的牙齿表面进行清洁。在被使用时，该牙线器能够绷紧设置在其上的牙线段。
背景技术
当前，已知各种利用牙线清洁牙齿表面的技术，以及辅助操纵牙线的装置。例如，公开号为USD403120的美国专利文献公开了一种牙线器(如图1所示)。该牙线器包括用于抓握的手柄30、用于清洁牙齿的牙线段11、以及用于固定和支撑牙线段11的支架20；手柄30有一端与支架20连接。这种类型的牙线器的形状有类似于英文字母“F”，因而通常被称为“F型牙线器”。另外，公开号为US5388600的美国专利文献公开了一种牙线器(如图2所示)。该牙线器也包括手柄30、牙线段11、以及支架20，不过该牙线器的支架20与手柄30的连接方式与前述“F型牙线器”不同。这种类型的牙线器的形状有类似英文字母“Y”，因而通常被称为“Y型牙线器”。
前述两种类型的牙线器，牙线段11都是固定在支架20上的。通常采用注塑成形工艺，将牙线纤维固定于支架20的第一支撑臂21B和第二支撑臂22B的自由端。如果采用多腔模具，则一次注塑就可制作出多个牙线器。用于制造牙线器的牙线，通常为尼龙或聚酯纤维长丝，或其它高模量纤维长丝。纤维的粗细程度大致在300-900但尼尔之间。支架20和牙线手柄30部分，一般采用聚丙烯或其它硬度合适的塑胶材料制造。已经有很多制造牙线器的方法被公开，在此不作赘述。
此外，还有其他类型的牙线器，例如，公开号为US4655233的美国专利文献公开了(如图3所示)：牙线段11不固定在牙线器的支架20上；当需要使用牙线器之前，将牙线段11安装上牙线支架20；使用完毕，将牙线段11从牙线支架20取下。
无论是牙线段固定在牙线支架上的牙线器(如USD403120、US5388600所 公开的牙线器)，还是牙线段可以装上、取下的牙线器(如US4655233所公开的牙线器)，都需要牙线段11在支架20上处于绷紧状态。绷紧的牙线段能取得较好的洁齿效果。
某些种类的牙线，比如用聚四氟乙烯(Polytetrafluoroethylene，PTFE)纤维制造的牙线，性能优良，质地柔软，深受消费者喜爱。但是，使用聚四氟乙烯牙线制造的牙线器，在使用的过程中，当受到较大力度拉伸时，牙线段(11)会被拉长，变得松弛(如图5所示)。这样会削弱牙线器的洁齿能力。因此，需要有一种牙线器，它能够让变得松弛的牙线段11恢复到绷紧状态。
公开号为US5829458美国专利文献公开了一种牙线器(如图4所示)，该牙线器能够让设置在它的支架上的、被拉伸以后变得松弛的牙线段11恢复到绷紧状态。此外，公开号为US4192330和USD424748的美国专利文献也公开了与US5829458类似的牙线器，这些牙线器也都能够让设置在它们各自的支架上的、被拉伸以后变得松弛的牙线段11恢复到绷紧状态。
不过，上述专利仍有不足之处：使用者需要比较费力地挤压牙线器的手柄，才能绷紧牙线段11。因而，操作牙线器、清洁牙齿的工作变得比较费力。
综上所述，设计和制造一种操作起来比较省力的、能够把变得松弛的牙线段11恢复到绷紧状态的牙线器，仍然很有必要。
发明内容
本发明的目的，在于提供一种牙线器，该牙线器能够让设置在其上的、变得松弛的牙线段恢复到绷紧状态；并且，操作该牙线器比操作现有的、具有绷紧牙线段功能的牙线器更省力。

具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似改进，因此本发明不受下面公开的具体实施的限制。
实施例1
图6、图7、图8分别是根据本发明的实施例1的牙线器在未被使用时，从不同的观察点观察，获得的透视图。图6、图7、图8显示实施例1在未被使用时呈现的状态。
在本实施例中，牙线器包括一个用于抓握的手柄30、一段用于清洁牙齿的牙线段11、以及一个用于固定和支撑牙线段11的支架20；所述手柄30有一端与支架20连接。
手柄30包括第一抓握部件31、第二抓握部件32以及铰链33；铰链33的转轴沿手柄30的纵向(图6、图7、图8中虚线A-A所示的方向)延伸；铰链33具有合适的长度(在实施例1中，其长度大致为5厘米)；铰链33的第一边缘与第一抓握部件31的部分边缘连接，铰链33的第二边缘与第二抓握部件32的部分边缘连接；并且，从第一抓握部件31延伸出第一基部21A；并从第一基部21A延伸出第一支撑臂21B；并且，从第二抓握部件32延伸出第二基部22A；并从第二基部22A延伸出第二支撑臂22B；使第一支撑臂21B和第二支撑臂22B彼此相隔合适的距离；并且，设置牙线段11，使其两端分别被固定在第一支撑臂21B的自由端和第二支撑臂22B的自由端。
其中，第一基部21A、第一支撑臂21B、第二基部22A以及第二支撑臂22B共同构成了支架20。牙线段11被固定和支撑在支架20上。
在本实施例中，第一抓握部件31与第二抓握部件32具有较厚的厚度，铰链33具有较薄的厚度。铰链33的第一边缘与第一抓握部件31的部分边缘连接，铰链33的第二边缘与第二抓握部件32的部分边缘连接。
当第一抓握部件31和/或第二抓握部件32被施加扭转压力时，具有较薄的厚度的铰链33能够被弯曲，借此，第一抓握部件31和/或第二抓握部件32能够绕铰链33的转轴(在实施例1中，铰链33的转轴与图6、图7、图8中的虚线A-A重叠)旋转，并能旋转合适的角度(通常，旋转角度在0度至30度之间)。
通常采用半刚性塑料，优选聚丙烯，来制造牙线器的支架20、手柄30、以及铰链33。当被施以扭转压力时，具有较薄的厚度的、用半刚性塑料制造的铰链33很容易被弯曲；因而，施加较小的压力，就能使第一抓握部件31和/或第二抓握部件32绕铰链33的转轴旋转。
需要适当地设置第一抓握部件31与第二抓握部件32的长度、宽度、厚度、以及外形，以满足如下条件：当第一抓握部件31绕铰链33的转轴旋转时，第二抓握部件32不会阻挡第一抓握部件31旋转合适的角度，并且，当第二抓握部件32绕铰链33的转轴旋转时，第一抓握部件31不会阻挡第二抓握部件32旋转合适的角度。
在本实施例中，在第一支撑臂21B的自由端和第二支撑臂22B的自由端设置牙线段11。牙线段11采用聚四氟乙烯纤维制造。聚四氟乙烯纤维性能优良，质地柔软，深受消费者喜爱。但是，聚四氟乙烯纤维在被使用的过程中，当受到较大力度拉伸时，会被拉长，变得松弛。图9显示实施例1在被使用后、牙线段11被拉长、变得松弛时呈现的状态。
牙线段11被拉长、变得松弛以后，牙线器的洁齿能力被削弱。此时，需要将变得松弛的牙线段重新绷紧，以获得正常的洁齿能力。
图10显示本实施例的牙线器的手柄被手指挤压时呈现的状态。
图11a是本实施例的牙线器在被使用时呈现的状态示意图。
在使用时，操作者用第一手指41和第二手指42抓住牙线器的手柄30；第 一手指41对第一抓握部件31施加压力，迫使第一抓握部件31围绕铰链33的转轴旋转，借此带动第一基部21A与第一支撑臂21B围绕铰链33的转轴旋转；同时，第二手指42对第二抓握部件32施加压力，迫使第二抓握部件32围绕铰链33的转轴旋转，借此带动第二基部22A与第二支撑臂22B围绕铰链33的转轴旋转；当第一抓握部件31与第二抓握部件32分别旋转合适的角度以后，第一支撑臂21B的自由端与第二支撑臂22B的自由端之间的距离，比旋转之前它们之间的距离更长，借此，固定在第一支撑臂21B的自由端和第二支撑臂22B的自由端之间的、变得松弛的牙线段11被重新绷紧。
在图11a中，第一箭头51指示第一手指41对第一抓握部件31施加压力的方向；第二箭头52指示第二手指42对第二抓握部件32施加压力的方向。
图11b是图11a中的牙线器沿C-C平面获取的剖面图。从图11b可以看出，当该牙线器被使用时，第一抓握部件31与第二抓握部件32分别围绕铰链33的转轴旋转了一定角度，例如，20度，导致第一抓握部件31与第二抓握部件32彼此靠近。也就是说，当第一抓握部件绕铰链的转轴旋转的第一远端和第二抓握部件绕铰链的转轴旋转的第二远端彼此靠近时，第一支撑臂的顶端和第二支撑臂的顶端之间的距离增大，牙线段倾向于被拉伸。
图12显示根据本实施例的牙线器被使用时呈现的状态。在图12中，第三箭头61指示第一支撑臂21B围绕铰链33的转轴旋转的方向；第四箭头62指示第二支撑臂22B围绕铰链33的转轴旋转的方向。图12显示，第一支撑臂21B与第二支撑臂22B分别旋转了合适的角度以后，牙线段11被重新绷紧。
可以适当地设置第一抓握部件31与第二抓握部件32的长度、宽度、厚度、以及外形，使它们在承受第一手指41或第二手指42施加的压力时，产生较大的旋转力矩；这样，使用者只需要使用较小的压力压紧手柄30，就能绷紧牙线段11，操作起来更省力。
实施例2
图13为根据本发明的实施例2的牙线器在未被使用时的透视图。实施例2是实施例1的一种改进。与实施例1相比，实施例2的改进之处在于：在第一抓握部件31和/或第二抓握部件32的外表面上设置多个突起部分34；借此，一 方面可以增加抓握部件外表面的摩擦系数，使其不易打滑；另一方面，也可以使牙线器的外观更漂亮。
实施例3
图14、图15、图16分别是根据本实施例的牙线器在未被使用时，从不同的观察点观察，获得的透视图。图14、图15、图16显示实施例3在未被使用时呈现的状态。
在本实施例中，牙线器包括用于抓握的手柄30、用于清洁牙齿的牙线段11、以及用于固定和支撑牙线段11的支架20；所述手柄30有一端与支架20连接。
手柄30包括第一抓握部件31、第二抓握部件32以及铰链33；铰链33的转轴沿手柄30的纵向(图14、图15、图16中虚线A-A所示的方向)延伸；铰链33具有合适的长度(在实施例3中，其长度大致为5厘米)；铰链33的第一边缘与第一抓握部件31的部分边缘连接，铰链33的第二边缘与第二抓握部件32的部分边缘连接；并且，从第一抓握部件31延伸出第一基部21A；并从第一基部21A延伸出第一支撑臂21B；并且，从第二抓握部件32延伸出第二基部22A；并从第二基部22A延伸出第二支撑臂22B；使第一支撑臂21B和第二支撑臂22B彼此相隔合适的距离；并且，设置牙线段11，使其两端分别被固定在第一支撑臂21B的自由端和第二支撑臂22B的自由端。
其中，第一基部21A、第一支撑臂21B、第二基部22A以及第二支撑臂22B共同构成了实施例3的支架20；牙线段11被固定和支撑在支架20上。
在本实施例中，第一抓握部件31与第二抓握部件32具有较厚的厚度，铰链33具有较薄的厚度。铰链33的第一边缘与第一抓握部件31的部分边缘连接，铰链33的第二边缘与第二抓握部件32的部分边缘连接。
当第一抓握部件31和/或第二抓握部件32被施加扭转压力时，具有较薄的厚度的铰链33能够被弯曲，借此，第一抓握部件31和/或第二抓握部件32能够绕铰链33的转轴(在实施例3中，铰链33的转轴与图14、图15、图16中的虚线A-A重叠)旋转，并能旋转合适的角度(通常，旋转角度在0度至30度之间)。
图17显示本实施例的牙线器的手柄被手指挤压时呈现的状态。
图18a是本实施例的牙线器在被使用时呈现的状态示意图。
在使用时，操作者用第一手指41和第二手指42抓住牙线器的手柄30；第一手指41对手柄30的顶部施加压力，同时，第二手指42对第一抓握部件31的边缘以及第二抓握部件32的边缘施加压力，迫使第一抓握部件31围绕铰链33的转轴旋转，借此带动第一基部21A与第一支撑臂21B围绕铰链33的转轴旋转；同时，迫使第二抓握部件32围绕铰链33的转轴旋转，借此带动第二基部22A与第二支撑臂22B围绕铰链33的转轴旋转；当第一抓握部件31与第二抓握部件32分别旋转合适的角度以后，第一支撑臂21B的自由端与第二支撑臂22B的自由端之间的距离，比旋转之前它们之间的距离更长，借此，固定在第一支撑臂21B的自由端与第二支撑臂22B的自由端之间的牙线段11被绷紧。
在图18a中，第一箭头51指示第一手指41对手柄30施加压力的方向；第二箭头52指示第二手指42对第一抓握部件31的边缘以及对第二抓握部件32的边缘施加压力的方向。
图18b是在图18中沿E-E平面获取的剖面图，显示本实施的牙线器在被使用时手柄呈现的状态。为便于观看，图18b已被放大。从图18b可以看出，当本实施的牙线器在被使用时，第一抓握部件31与第二抓握部件32分别围绕铰链33的转轴旋转了一定角度，例如，15度，导致第一抓握部件31与第二抓握部件32彼此远离。也就是说，当第一抓握部件绕铰链的转轴旋转的第一远端和第二抓握部件绕铰链的转轴旋转的第二远端彼此远离时，第一支撑臂的顶端和第二支撑臂的顶端之间的距离增大，牙线段倾向于被拉伸。
图19显示根据本实施例的牙线器被使用时呈现的状态。在图19中，第三箭头61指示第一支撑臂21B围绕铰链33的转轴旋转的方向；第四箭头62指示第二支撑臂22B围绕铰链33的转轴旋转的方向。图19显示，第一支撑臂21B与第二支撑臂22B分别旋转了合适的角度以后，牙线段11被绷紧。
实施例4
图20为根据本发明的实施例4的牙线器在未被使用时的透视图。本实施例中的牙线器是实施例3的牙线器的一种改进。与实施例3的牙线器相比，本实施例中的牙线器的改进之处在于：在第一抓握部件31的尾部设置牙签部件35。 牙签部件35可用于剔牙，这增加了牙线器的功能。当然，也可以在第二抓握部件32的尾部设置牙签部件35，这是不言而喻的。
实施例5
图21为根据本发明的实施例5的牙线器在未被使用时的透视图。本实施例中的牙线器是实施例3的牙线器的一种改进。与实施例3的牙线器相比，本实施例中的牙线器的改进之处在于：在第一抓握部件31和第二抓握部件32的边缘上设置缺口36。缺口36可以增加抓握部件的边缘的摩擦系数，使其不易打滑。当然，也可以仅仅在第一抓握部件31或第二抓握部件32的边缘上设置缺口36，这也是不言而喻的。
实施例6
图22、图23分别是根据本发明的实施例6的牙线器在未被使用时，从不同的观察点观察，获得的透视图。图22、图23显示实施例6在未被使用时呈现的状态。
在本实施例中，牙线器包括用于抓握的手柄30、用于清洁牙齿的牙线段11、以及用于固定和支撑牙线段11的支架20；所述手柄30有一端与支架20连接。
手柄30包括第一抓握部件31、第二抓握部件32以及铰链33；铰链33的转轴沿手柄30的纵向(图22、图23中虚线A-A所示的方向)延伸；铰链33具有合适的长度(在本实施例中，其长度大致为6厘米)；铰链33的第一边缘与第一抓握部件31的部分边缘连接，铰链33的第二边缘与第二抓握部件32的部分边缘连接；并且，从第一抓握部件31延伸出第一基部21A；并从第一基部21A延伸出第一支撑臂21B；并且，从第二抓握部件32延伸出第二基部22A；并从第二基部22A延伸出第二支撑臂22B；使第一支撑臂21B和第二支撑臂22B彼此相隔合适的距离；并且，设置牙线段11，使其两端分别被固定在第一支撑臂21B的自由端和第二支撑臂22B的自由端。
其中，第一基部21A、第一支撑臂21B、第二基部22A以及第二支撑臂22B共同构成了本实施的支架20；牙线段11被固定和支撑在支架20上。
在本实施例中，第一抓握部件31与第二抓握部件32具有较厚的厚度，铰链33具有较薄的厚度。图23J还显示，铰链33的第一边缘与第一抓握部件31 的部分边缘连接，铰链33的第二边缘与第二抓握部件32的部分边缘连接。
当第一抓握部件31和/或第二抓握部件32被施加扭转压力时，具有较薄的厚度的铰链33能够被弯曲，借此，第一抓握部件31和/或第二抓握部件32能够绕铰链33的转轴(在本实施例中，铰链33的转轴与图22、图23中的虚线A-A重叠)旋转，并能旋转合适的角度(通常，旋转角度在0度至30度之间)。
图24显示本实施例的牙线器的手柄被手指挤压时呈现的状态。
图25a是本实施例的牙线器在被使用时呈现的状态示意图。
在使用时，操作者用第一手指41和第二手指42抓住牙线器的手柄30；第一手指41对第一抓握部件31施加压力，迫使第一抓握部件31围绕铰链33的转轴旋转，借此带动第一基部21A与第一支撑臂21B围绕铰链33的转轴旋转；同时，第二手指42对第二抓握部件32施加压力，迫使第二抓握部件32围绕铰链33的转轴旋转，借此带动第二基部22A与第二支撑臂22B围绕铰链33的转轴旋转；当第一抓握部件31与第二抓握部件32分别旋转合适的角度以后，第一支撑臂21B的自由端与第二支撑臂22B的自由端之间的距离，比旋转之前它们之间的距离更长，借此，固定在第一支撑臂21B和第二支撑臂22B的自由端之间的牙线段11被绷紧。
在图25a中，第一箭头51指示第一手指41对第一抓握部件31施加压力的方向；第二箭头52指示第二手指42对第二抓握部件32施加压力的方向。
图25b是在图25a中沿G-G平面获取的剖面图。从图25b可以看出，当该牙线器被使用时，第一抓握部件31与第二抓握部件32分别围绕铰链33的转轴旋转了大致15度，导致第一抓握部件31与第二抓握部件32彼此靠近。
实施例7
图26、图27、图28分别是本发明的实施例7在未被使用时，从不同的观察点观察，获得的透视图。图26、图27、图28显示实施例7在未被使用时呈现的状态。

当第一抓握部件31和/或第二抓握部件32被施加扭转压力时，具有较薄的厚度的铰链33能够被弯曲，借此，第一抓握部件31和/或第二抓握部件32能够绕铰链33的转轴(在本实施例中，铰链(33)的转轴与图26、图27、图28中的虚线A-A重叠)旋转，并能旋转合适的角度(通常，旋转角度在0度至30度之间)。
图29显示本实施例的牙线器的手柄被手指挤压时呈现的状态。

实施例8
图30、图31、图32分别是本发明的实施例8在未被使用时，从不同的观察点观察，获得的透视图。图30、图31、图32显示实施例8在未被使用时呈现的状态。
在本实施例中，牙线器包括用于抓握的手柄30、用于清洁牙齿的牙线段11、以及用于固定和支撑牙线段11的支架20；所述手柄30有一端与支架20连接。
手柄30包括第一抓握部件31、第二抓握部件32以及铰链33；铰链33的转轴沿手柄30的纵向(图30、图32中虚线A-A所示的方向)延伸；铰链33具有合适的长度(在本实施中，其长度大致为6厘米)；铰链33的第一边缘与第一抓握部件31的部分边缘连接，铰链33的第二边缘与第二抓握部件32的部分边缘连接；并且，从第一抓握部件31延伸出第一基部21A；并从第一基部21A延伸出第一支撑臂21B；并且，从第二抓握部件32延伸出第二基部22A；并从第二基部22A延伸出第二支撑臂22B；使第一支撑臂21B和第二支撑臂22B彼此相隔合适的距离；并且，设置牙线段11，使其两端分别被固定在第一支撑臂21B的自由端和第二支撑臂22B的自由端。

实施例9
图34为根据本发明的实施例9的牙线器在未被使用时的透视图。本实施例的牙线器与实施例8的牙线器大致相同，区别在于本实施例的牙线器包括三个铰链33a、33b和33c，并且第一抓握部件31和第二抓握部件32具有弧形外表面。三个铰链33a、33b和33c具有相同的转轴。
实施例10
图35为根据本实施例的牙线器在未被使用时的结构示意图，图36为根据本实施例的牙线器在被使用时的结构示意图。
在本实施例中，如图35和36所示，牙线器包括第一基部21A、第二基部22A、抓握部件37、第一支撑臂21B、第二支撑臂22B、牙线段11、铰链33和释放-紧固机构70。
第一基部21A与第二基部22之间存在缝隙。抓握部件37的顶端连接至第一基部21A，第一支撑臂22B的底端连接至第一基部21A。第二支撑臂22B的底端连接至第二基部22A，第二支撑臂21B与第一支撑臂22B间隔开以在第一支撑臂21B与第二支撑臂22B之间限定间隔。牙线段11包括第一端和第二端，第一端连接到第一支撑臂21B的顶端，第二端连接到第二支撑臂22B的顶端。铰链33的两端分别连接到第一基部21A和第二基部22A，并且铰链33沿抓握部件37的厚度方向延伸。释放-紧固机构70是可操作的，其设置为可在释放位 置和紧固位置之间切换，当操作该释放-紧固机构70处于紧固位置时，第一支撑臂21B的顶端与第二支撑臂22B的顶端之间的距离大于当该释放-紧固机构70处于释放位置时第一支撑臂21B的顶端与第二支撑臂22B的顶端之间的距离。铰链33的厚度通常被加厚，即，大于第一基部21A和第二基部22A的厚度，从而提高该铰链的耐用度。
在本实施例中，释放-紧固机构70包括第一固定杆71、第二固定杆72、第一铰链73、第二铰链74和第三铰链75。第一铰链73的两端分别连接至第一固定杆71和第一支撑臂21B，第二铰链74的两端分别连接至第一固定杆71和第二固定杆72，第三铰链75的两端分别连接至第二固定杆72和第二支撑臂22B，第一铰链73、第二铰链74和第三铰链75的转轴均沿第一支撑臂21B和第二支撑臂22B的厚度方向延伸。第一固定杆71与第二固定杆72的长度被配置以使得，当释放-紧固机构可操作地从释放位置切换到紧固位置时，第一支撑臂21B的顶端与第二支撑臂22B的顶端之间的距离被扩张到预设的长度，并且大于释放-紧固机构70处于释放位置时第一支撑臂21B的顶端与第二支撑臂22B的顶端之间的距离。
为了使牙线器从初始状态转动到工作状态，使用者需要用手指挤压释放-紧固机构70，以迫使第一固定杆71与第二固定杆72绕铰链转动，直到第一固定杆71与第二固定杆72分别紧贴第一基部21A和第二基部22A的内壁，至此，第一固定杆71与第二固定杆72被第一基部21A和第二基部22A阻挡，不能再转动。
在释放-紧固机构被手指挤压，转动到基部的过程中，第一支撑臂21B被第一固定杆71推动，带动第一基部21A绕铰链33转动，同时，第二支撑臂22B被第二固定杆72推动，带动牙线器的第二基部22A绕铰链33转动，在这个过程中，第一支撑臂21B的顶端与第二支撑臂22B的顶端彼此逐渐远离，亦即这两个顶端之间的距离逐渐扩大。当第一固定杆71与第二固定杆72分别紧贴第一基部21A和第二基部22A的内壁时，第一支撑臂21B的顶端与第二支撑臂22B的顶端之间的距离不再扩大，达到预设的长度。
当第一支撑臂21B的顶端与第二支撑臂22B的顶端之间的距离被扩张到预 设的长度以后，牙线段11因承受第一支撑臂21B与第二支撑臂22B施加的张力而被绷紧；同时，当达到预设的长度以后，第一支撑臂21B的顶端与第二支撑臂22B的顶端之间的距离不再增加，牙线段11受到的拉力不再增加，以确保牙线段不会因为受力过大而被从两支撑臂的顶端拔出。
需要特别关注的是，铰链33的厚度被加厚。加厚的铰链使牙线器更为稳固，当牙线段受到拉力时，牙线器的摆动幅度因此降低。
实施例11
图37为根据本实施例的牙线器在未被使用时的结构示意图，图38为根据本实施例的牙线器在被使用时的结构示意图。
本实施例的牙线器与实施例10的牙线器大致相同，区别在于释放-紧固机构的结构。
在本实施例中，如图37和38所示，释放-紧固机构还包括第一固定片81和第二固定片82。第一固定片81包括第一下表面，该第一固定片81的部分边缘连接到第一固定杆，并且，其与第一固定杆之间的连接角度以及连接位置被配置以使得，当释放-紧固机构可操作地从释放位置切换到紧固位置时，第一固定片81的第一下表面紧贴第一基部的上表面。第二固定片82包括第一上表面，该第二固定片82的部分边缘连接到第二固定杆，并且，其与第二固定杆之间的连接角度以及连接位置被配置以使得，当释放-紧固机构可操作地从释放位置切换到紧固位置时，第二固定片82的第一上表面紧贴第二基部的下表面。
实施例12
图39为根据本实施例的牙线器在未被使用时的结构示意图，图40为根据本实施例的牙线器在被使用时的结构示意图。
本实施例的牙线器与实施例10的牙线器大致相同，区别在于释放-紧固机构的结构。
如图39和40所示，释放-紧固机构包括可活动地连接至第二支撑臂22B的固定杆91，以及设置在第一基部21A上的缺口92。在本实施例中，固定杆91通过铰链连接至第二支撑臂22B。缺口92的形状与固定杆91的自由端的形状相匹配，使得当释放-紧固机构从释放位置切换到紧固位置时，固定杆91的自由端 能够与缺口92紧密贴合。
该释放-紧固机构还包括第一阻挡片93、第二阻挡片94和第三阻挡片95。第一阻挡片93和第二阻挡片94设置在缺口92上，当释放-紧固机构可操作地从释放位置切换到紧固位置时，即，固定杆91的自由端与缺口92紧密贴合时，第一阻挡片93的下表面紧贴固定杆91的上表面，第二阻挡片94的上表面紧贴固定杆91的下表面，从而夹紧固定杆91，并且限制固定杆91在第一基部21A的厚度方向上的晃动。第三阻挡片95设置在第二基部22A和第二支撑臂22B的连接处，位于固定杆91的上方或下方，在本实施例中，其位于固定杆91的下方，当当释放-紧固机构可操作地从释放位置切换到紧固位置时，第三阻挡片的上表面紧贴固定杆的下表面，从而进一步限制固定杆91在第二基部22A的厚度方向上的晃动。
实施例13
图41-42为根据本实施例的牙线器在未被使用时分别从两个观察点观察的透视图，图43为本实施例的牙线器的固定杆的结构示意图，图44为根据本实施例的牙线器在被使用时的结构示意图。
本实施例的牙线器与实施例10的牙线器大致相同，区别在于释放-紧固机构的结构。
如图41-44所示，释放-紧固机构包括可活动连接至第二支撑臂22B的固定杆101、设置在第一基部21A上的第一下陷部105和第二下陷部106、设置在第一基部21A和第一支撑臂21B的连接处的阻挡片104、设置在第一支撑臂21B上的防滑块107。在本实施例中，固定杆101通过铰链连接至第二支撑臂22B。特别地，如图43所示，固定杆101包括两个沿该固定杆101的宽度方向延伸的第一固定片102和第二固定片103，第一固定片102和第二固定片103交错布置在固定杆101的厚度方向的两端。
阻挡片104与第一基部21A和第一支撑臂21B之间的连接角度以及连接位置被配置以使得，当释放-紧固机构可操作地从释放位置切换到紧固位置时，阻挡片104的上表面紧贴固定杆101靠近该固定杆101的自由端的一部分的下表面，并且该阻挡片104的其中一个边缘与第二固定片103的其中一个边缘紧贴。
第一下陷部105配置为可与第二固定片103互补地接合，当释放-紧固机构可操作地从释放位置切换到紧固位置时，第一下陷部105的下表面紧贴第二固定片103的上表面。第二下陷部106配置为可与第一固定片103的一部分互补地接合，当释放-紧固机构可操作地从释放位置切换到紧固位置时，第二下陷部106的上表面紧贴第一固定片102的下表面。
防滑块107设置在第一支撑臂21B上朝向第二支撑臂22B的一侧，其沿第一支撑臂21B的长度方向延伸，并且其宽度逐渐递减，即靠近第一基部21A的一端具有最大宽度，远离第一基部21A的一端具有最小宽度。防滑块107在第一支撑臂21B上的位置定位为使得当释放-紧固机构可操作地从释放位置切换到紧固位置时，该防滑块107恰好能将固定杆101的自由端卡在该防滑块107与第一基部21A之间，限制该自由端的移动。防滑块107渐变的宽度，使得当释放-紧固机构可操作地从释放位置切换到紧固位置时，容易将固定杆101的自由端卡入，而当释放-紧固机构可操作地从紧固位置切换到释放位置时，需要耗费较大力气将固定杆101的自由端推出。该防滑块107与固定杆101形成卡扣配置。
实施例14
图44为根据本实施例的牙线器在未被使用时的结构示意图，图45为根据本实施例的牙线器在被使用时的结构示意图。
本实施例的牙线器与实施例10的牙线器大致相同，区别在于释放-紧固机构的结构。在本实施例中，释放-紧固机构包括第一固定杆71、第二固定杆72、第一铰链73、第二铰链74和第三铰链75。第一铰链73的两端分别连接至第一固定杆71和第一支撑臂21B，第二铰链74的两端分别连接至第一固定杆71和第二固定杆72，第三铰链75的两端分别连接至第二固定杆72和第二支撑臂22B。与实施例10中，第一铰链73、第二铰链74和第三铰链75的转轴均沿第一支撑臂21B和第二支撑臂22B的厚度方向延伸不同，在本实施例中，第一铰链73、第二铰链74和第三铰链75的转轴均沿第一支撑臂21B和第二支撑臂22B的延伸方向延伸。这样，当本实施例的释放-紧固机构处于释放位置时，第一固定杆71和第二固定杆72是朝第一支撑臂21B和第二支撑臂22B的厚度方向突出的。
此外，在本实施例中，第一固定杆71具有第一支撑壁76，第二固定杆72具有第二支撑壁77。第一支撑壁76与第二支撑壁77的厚度被配置以使得，当释放-紧固机构可操作地从释放位置切换到紧固位置时，第一支撑壁76与第二支撑壁77彼此紧贴并能承受压力，以阻止第一固定杆71与第二固定杆72进一步被压下。优选地，第一固定杆71的厚度在第一支撑壁76处最大，并且第二固定杆72的厚度在第二支撑壁77处最大。
实施例15
图46为根据本实施例的牙线器在未被使用时的结构示意图，图47为根据本实施例的牙线器在被使用时的结构示意图。
本实施例的牙线器与实施例10的牙线器大致相同，区别在于：抓握部件37包括第一抓握部件37A和第二抓握部件37B，第一抓握部件37A连接至第一基部21A，第二抓握部件37B连接至第二基部22A，第一抓握部件37A和第二抓握部件37B之间隔开与第一基部21A和第二基部22A之间相同的缝隙，铰链33位于第一抓握部件37A和第二抓握部件37B的末端。

实施例18
图52为根据本实施例的牙线器在未被使用时的结构示意图，图53为根据本实施例的牙线器在被使用时的结构示意图。
在本实施例中，如图52-53所示，牙线器包括第一基部21A、第二基部22A、 第一支撑臂21B、第二支撑臂22B、铰链33、牙线段11和抓握部件37。第二基部22A铰接至第一基部21A，并且可操作地在释放位置和紧固位置之间切换。具体地，第一基部21A和第二基部22A分别连接至铰链33的两端，铰链33的转轴沿第一基部21A和第二基部22A的宽度方向延伸。抓握部件37的顶端连接至第一基部21A。第一支撑臂21B的底端连接至第一基部21A，第二支撑臂22B的底端连接至第二基部22A，第一支撑臂21B与第二支撑臂22B间隔开以在第一支撑臂21B与所述第二支撑臂22B之间限定间隔。牙线段11包括第一端和第二端，第一端连接到第一支撑臂21B的顶端，第二端连接到第二支撑臂22B的顶端。当第二基部22A从所述释放位置切换到所述紧固位置时，第二基部22A与第一基部21A接合，并且第一支撑臂21B的顶端与第二支撑臂22B的顶端之间的距离大于当第二基部22A处于释放位置时第一支撑臂21B的顶端与第二支撑臂22B的顶端之间的距离。
此外，第一基部21A具有与第二基部22A接合的第一支撑壁，第二基部22A具有与第一基部21A接合的第二支撑壁，当第二基部22A处于紧固位置时，第一支撑壁与第二支撑壁彼此紧贴并能承受压力，以阻止第二基部22A进一步被转动。
在使用过程中，使用者推动第二基部22A绕第一基部21A转动，直至第二基部22A的第二支撑壁与第一基部21A的第一支撑壁贴紧接合，此时，第一支撑臂的顶端与第二支撑臂的顶端之间的距离增大，从而拉伸牙线段使得该牙线端紧绷。第一支撑壁与第二支撑壁的长度和宽度配置为使得，当第二基部22A处于紧固位置时，第二基部22A不容易进一步被转动，也不容易松脱。
实施例19
图54为根据本实施例的牙线器在未被使用时的结构示意图，图55为根据本实施例的牙线器在被使用时的结构示意图。
本实施例的牙线器与实施例18的牙线器大致相同，区别在于：在实施例18中，牙线器是F型牙线器，而在本实施例中，牙线器是Y型牙线器。
实施例20
图56为根据本实施例的牙线器在未被使用时的结构示意图，图57为根据 本实施例的牙线器在被使用时的结构示意图。
本实施例的牙线器与实施例3的牙线器大致相同，区别在于本实施例的牙线器还包括释放-紧固机构70。
如图56和57所示，释放-紧固机构70包括拱形构件，该拱形构件的一端连接至第一基部21A，该拱形构件的另一端连接至第二基部22A，以致在第一基部21A和第二基部22A之间形成拱形。该拱形构件的厚度和拱形的高度被配置以使得，当承受使用者施加的压力时，拱形部件将从释放位置切换到紧固位置，第一基部21A的第一支撑壁与第二基部22A的第二支撑壁彼此紧贴并能承受压力，从而阻止第一基部21A和第二基部22A相对彼此的进一步转动。
拱形构件70通常由半刚性材料，例如，聚丙烯(polypropylene)塑料，制成。对于图56所示的牙线器，拱形构件向上拱起，当使用者对拱形构件施加自上而下的压力时，由半刚性材料制成的拱形部件将产生形变，使拱形的方向发生翻转，如图57所示。在拱形翻转的同时，第一抓握部件31和第二抓握部件32将绕铰链转动，借此带动第一支撑臂和第二支撑臂转动使得第一支撑臂的末端和第二支撑臂的末端之间的距离增大，从而将牙线段绷紧。当牙线段被绷紧以后，牙线段将对第一支撑臂和第二支撑臂施加阻力，以阻止第一抓握部件31和第二抓握部件32继续转动。同时，当拱形构件翻转到紧固状态以后，除非受到外力挤压，否则拱形部件将一直保持翻转以后的状态。借此，即使不再对手柄施加压力，牙线段也会一直保持绷紧状态。
实施例21
图58为根据本实施例的牙线器在未被使用时的结构示意图，图59为根据本实施例的牙线器在被使用时的结构示意图。
本实施例的牙线器与实施例20的牙线器大致相同，区别在于本实施例的牙线器的第一抓握部件31比较短，而第二抓握部件32比较宽。
如图58和59所示，第一抓握部件31连接至第一基部的一端与第二抓握部件连接至第二基部的一端齐平，但是第一抓握部件31明显短于第二抓握部件32。此外，第二抓握部件32明显宽于第一抓握部件31，例如，第二抓握部件32的宽度近似为第一抓握部件31的宽度的两倍。
采用本实施例的牙线器，使用者只需要抓握第二抓握部件31，而无需抓握第一抓握部件32。
实施例22
本实施例的牙线器包括可分离的牙线支架和抓握部件，牙线支架适于可拆卸地安装至抓握部件。
图60为根据本实施例的牙线器在未工作时与抓握部件分离的牙线支架的透视图。牙线支架20包括第一基部21A、第二基部22A、铰链33、第一支撑臂21B、第二支撑臂22B、牙线端11。铰链33的两端分别连接至第一基部21A和第二基部22A，并且铰链33的转轴沿第一基部21A和第二基部22A的厚度方向延伸。第一支撑臂21B的底端连接至第一基部21A，第二支撑臂22B的底端连接至第二基部22A，第一支撑臂21B与第二支撑臂22B间隔开以在第一支撑臂21B与第二支撑臂22B之间限定间隔。牙线段11包括第一端和第二端，第一端连接到第一支撑臂21B的顶端，第二端连接到第二支撑臂22B的顶端。
在本实施例中，牙线支架20还包括设置在第一基部21A上的第一插入部件21C，以及设置在第二基部22A上的第二插入部件22C。
图61为本实施例的牙线器在未工作时与牙线支架分离的抓握部件的透视图。如图所示，抓握部件37设置有带有插入槽372的安装头部371。第一插入部件21C和第二插入部件22C均设置为可与插入槽372卡扣连接，并且，当第一插入部件21C和第二插入部件22C同时与插入槽372卡扣连接时，牙线支架20安装在抓握部件37上。当牙线支架20安装在抓握部件37上时，第一支撑臂21B的顶端与第二支撑臂22B的顶端之间的距离大于当牙线支架20从抓握部件37上拆卸下来时第一支撑臂21B的顶端与第二支撑臂22B的顶端之间的距离。
图62为本实施例的牙线器在牙线支架准备安装进抓握部件时的透视图。如图所示，在牙线支架20安装进抓握部件37之前，需以相对方向按压第一基部21A和第二基部22A使得第一基部21A和第二基部22A绕铰链33旋转，以致第一基部21A和第二基部22A紧贴在一起。此时，第一插入部件21C和第二插入部件22C也紧贴在一起，第一支撑臂的顶端与第二支撑臂的顶端之间的距离增大，从而拉伸牙线段，使得牙线段紧绷。此后，第一插入部件21C和第二插 入部件22C将插入安装头部371的插入槽372中，如图63所示，通过第一插入部件21C和第二插入部件22C与插入槽372的卡扣连接使得牙线支架20固定在安装头部371中，并且插入槽372保持第一插入部件21C和第二插入部件22C紧贴在一起，从而防止第一基部21A和第二基部22A的分离，牙线段能够保持紧绷。
第一插入部件和第二插入部件的外围形状被配置为，当第一插入部件和第二插入部件紧贴在一起插入安装头部的插入槽时，第一插入部件和第二插入部件组成的插入部件组件的外部轮廓紧贴插入槽的内部轮廓。第一插入部件和第二插入部件可能配置为分别从第一基部和第二基部向外延伸的同时宽度逐渐变窄，并且，插入槽可能配置为从用于接收插入部件组件接收端到末端延伸的同时宽度逐渐变窄。
实施例23
图64为本实施例的牙线器在未工作时与抓握部件分离的牙线支架的透视图，图65为本实施例的牙线支架在准备安装进抓握部件时的透视图。
本实施例的牙线器与实施例22的牙线器大致相同，区别在于连接第一基部和第二基部的铰链的转轴沿第一基部和第二基部的长度方向延伸。
如图64所示，牙线支架的铰链33的两端分别连接至第一基部21A和第二基部22A，并且铰链33的转轴沿第一基部21A和第二基部22A的长度方向延伸。在牙线支架安装进抓握部件之前，需旋转第一基部21A和第二基部22A至平行位置，使得第一基部21A和第二基部22A紧贴在一起，如图65所示，此时，本实施例的牙线支架与实施例22中在准备安装进抓握部件之前的牙线支架外形一致。
实施例24
图66为本实施例的牙线器的牙线支架的结构示意图，图67为本实施例的牙线器的抓握部件的插入槽的分解图，图68为本实施例的牙线器在牙线支架安装进抓握部件中时的透视图，为便于观察将安装头部分解为两个部分。
本实施例的牙线器与实施例22的牙线器大致相同，区别在于牙线支架与抓握部件的连接方式。
在本实施例中，如图66所示，铰链33连接在第一基部21A和第二基部22A的底部。在第一基部21A和第二基部22A之间、铰链33的上方设置有缺口111，缺口111的宽度从开口位置向下逐渐递减。如图67所示，抓握部件37设置有带有插入槽的安装头部，该插入槽适合于同时卡扣连接第一基部21A和第二基部22A。该插入槽内设置有止动件112，在本实施例中，止动件112为楔形块。止动件112从插入槽的底部，例如，中间位置，向外延伸，并且宽度逐渐递减。
缺口111设置为当第一基部21A和第二基部22A插入插入槽时，缺口111的开口张大。缺口111的内轮廓形状与止动件112的外轮廓形状相似，并且缺口111的最大宽度小于止动件112的最大宽度。
抓握部件37的安装头部的宽度，即插入槽的宽度，大于分别固定在第一基部21A和第二基部22A上的第一支撑臂和第二支撑臂的底部之间的距离，因此当牙线支架卡扣连接至插入槽时，第一基部21A和第二基部22A绕铰链33转动而彼此远离，从而导致固定在第一基部21A上的第一支撑臂的顶端与固定在第二基部22A上的第二支撑臂的顶端之间的距离增大，牙线段被绷紧。同时，止动件112插入缺口111，并且止动件112的外轮廓紧贴缺口111的内轮廓，从而阻止牙线支架左右摆动。
实施例25
图69为本实施例的牙线器在未工作时带有牙线段的支撑臂的透视图，图70为本实施例的牙线器在未工作时抓握部件的头部的放大透视图，图71为本实施例的牙线器在被使用时的透视图。
本实施例的牙线器与实施例3的牙线器大致相同，区别在于支撑臂与基部可分离。
如图69所示，第一支撑臂21B的底端设置有第一插入块21D，第二支撑臂22B的底端设置有第二插入块22D，在第一支撑臂21B的顶端和第二支撑臂22B的顶端之间连接有牙线段11。如图70所示，第一基部21A设置有第一插入槽21E，第二基部22A设置有第二插入槽22E。第一插入块21D可卡扣连接至第一插入槽21E，第二插入块22D可卡扣连接至第二插入槽22E。
在使用前，需将第一插入块21D和第二插入块22D分别插入第一插入槽21E 和第二插入槽22E中，通过第一插入块21D和第一插入槽21E之间的卡扣配置，以及第二插入块22D和第二插入槽22E之间的卡扣配置，第一支撑臂21B和第二支撑臂22B分别固定在第一基部21A和22A上，如图71所示。本实施例的牙线器的使用过程与实施例3的牙线器的使用过程相同，在此不再赘述。
根据本实施例的牙线器，在牙线段需要更换时，无需更换整个牙线器，只需更换连接该牙线段的支撑臂，这样既便于更换又节约资源。
实施例26
图72为本实施例的牙线器在未安装有牙线时的局部放大透视图，图73为本实施例的牙线的透视图，图74为本实施例的牙线器在安装牙线时的局部放大透视图，图75为本实施例的牙线器在安装牙线后的局部放大透视图。
本实施例的牙线器与实施例3的牙线器大致相同，区别在于在支撑臂上设置环形的、可移除的牙线。
如图72所示，第一支撑臂21B和第一基部21A上设置有沿着该第一支撑臂21B和该第一基部21A的外侧面延伸的第一卡槽21F，第二支撑臂22B和第二基部22A上设置有沿着该第二支撑臂22B和该第二基部22A的外侧面延伸的第二卡槽22F。如图73所示，牙线为环形圈，其适于夹持在第一卡槽21F和第二卡槽22F内，从而通过可移除的方式连接在第一基部21A、第二基部22A、第一支撑臂21B、第二支撑臂22B上。
如图74所示，在将牙线11安装在牙线器上之前，使用者需对第一抓握部件和第二抓握部件施加压力使得第一抓握部件和第二抓握部件绕铰链旋转而彼此靠近，从而带动第一基部和第二基部也彼此靠近，直至可将牙线11套在第一基部21A、第二基部22A、第一支撑臂21B、第二支撑臂22B的外侧。在将牙线11套在第一基部21A、第二基部22A、第一支撑臂21B、第二支撑臂22B的外侧后，使用者松开第一抓握部件和第二抓握部件，牙线11将夹持在第一卡槽21F和第二卡槽22F内，并且在第一支撑臂21B的顶端和第二支撑臂22B的顶端之间限定一段牙线，如图75所示。本实施例的牙线器的使用过程与实施例3的牙线器的使用过程相同，在此不再赘述。
根据本实施例的牙线器，在牙线需要更换时，无需更换整个牙线器，只需 更换连接该牙线，这样既便于更换又节约资源。
