Description

牙刷 技术领域
本发明涉及一种牙刷，特别是一种方便竖刷的牙刷。
背景技术
常用的牙刷包括刷头和刷杆，刷头的中心线与刷杆的中心线相重合。使用这种结构的牙刷，人们习惯采用横刷的方式，即牙刷的运动方向垂直于牙缝的方向。这种刷牙方式不利于清除牙缝中的残渣，也容易造成牙齿表面的过分磨损。
为了解决横刷的缺点问题，现已公开的一种竖刷牙刷将刷头铰接在刷把上，在竖刷的过程中需多次旋转刷头，使用十分不方便。
发明内容
本发明的目的是提供一种易于清洁牙齿又使用方便的竖刷牙刷。
本发明提供了一种牙刷，包括一个刷头和一个刷柄。
刷头具有一个刷板。刷板的一个侧面设置有刷毛。刷板沿一长度方向具有相对设置的第一端部和第二端部。
刷柄包括连接杆、第一刷杆、和第二刷杆。连接杆连接于刷板的第一端部。第一刷杆的一端连接于连接杆。第二刷杆连接于第一刷杆的另一端，此另一端在长度方向上靠近第二端部。第二刷杆和第一刷杆限定了一个基准面。刷板与基准面间具有一个倾角。连接杆与基准面间具有一个翘角。
在基准面内所述第一刷杆与长度方向之间具有第一夹角。第二刷杆与长度方向之间具有第二夹角。
第一刷杆与连接杆具有一个连接位置，此连接位置与第一端部沿着长度方向具有第一距离。第一距离与刷板在长度方向的长度的比例为0至1： 5。
在牙刷的再一种示意性的实施方式中，其中倾角的范围为0≤β 0≤60°。
在牙刷的又一种示意性的实施方式中，其中所述翘角的范围为0≤β 1≤90°。
在牙刷的又一种示意性的实施方式中，其中第一夹角的范围为0≤α 1≤35°。
在牙刷的又一种示意性的实施方式中，其中第二夹角的范围为10°≤α 2≤90°。
在牙刷的又一种示意性的实施方式中，基准面由第二刷杆的轴线和第一刷杆的轴线限定。
在牙刷的又一种示意性的实施方式中，所述牙刷进一步包括一个连接于第二刷杆的手持部，以达到美观和平衡的效果。
本发明提供的牙刷使用时无需转动刷头，即可实现两侧牙齿的竖刷，使用十分方便。本发明的牙刷在刷牙时可以有效清除牙缝中的食物残渣、减少牙面的磨损、按摩牙龈防止牙龈过早萎缩。

具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图说明本发明的具体实施方式，在各图中相同的标号表示相同或结构相似但功能相同的部件。
为使图面简洁，各图中的只示意性地表示出了与本发明相关的部分，它们并不代表其作为产品的实际结构和真实比例。
在本文中，“示意性”表示“充当实例、例子或说明”，不应将在本文中被描述为“示意性”的任何图示、实施方式解释为一种更优选的或更具 优点的技术方案。
在本文中，“第一”、“第二”等仅用于彼此的区分，而非表示它们的重要程度及顺序等。
本文中的“倾角”和“翘角”均为相交所形成的最小正角。
图1为本发明的牙刷一种示意性实施方式的结构示意图，图2为本发明的牙刷另一种示意性实施方式的结构示意图。
如图1和2所示，牙刷包括一个刷头10和一个刷柄20。
刷头10具有一个刷板12。刷板12的一个侧面设置有刷毛14，且刷板12沿一长度方向X具有相对设置的第一端部122和第二端部124。刷毛14可以植入刷板12中或者与刷板12一体成型。如图1所示，在一种具体实施方式中，刷板12是中心对称结构，因此长度方向X为沿着刷板12的对称轴方向。刷板12的对称轴所在的直线为刷板的中心线121。
刷柄20包括一个连接杆22、一个第一刷杆24、和一个第二刷杆26。连接杆22连接于刷板12的第一端部122。第一刷杆24的一端连接于连接杆22；第一刷杆24的另一端连接于第二刷杆26，此另一端在长度方向X上靠近第二端部124，且第一刷杆24和第二刷杆26限定了一个基准面Z。在一中示意性实施方式中，第一刷杆24和第二刷杆26均为对称结构，故基准面Z由第一刷杆24的轴线和第二刷杆26的轴线限定。以上所说的连接可以呈圆弧状形成弯头连接的结构，该结构在刷两侧牙齿时可带动脸上腮帮运动，促进面部血液循环。连接杆的倾斜设计与第一刷杆的连接处设计成圆弧过渡，有利于牙刷更加灵活地进入左边口腔，清洁左侧牙齿。
刷板12与基准面Z间具有一个倾角β 0，连接杆22与基准面Z间具有一个翘角β 1。在基准面Z内，第一刷杆24与长度方向X之间具有第一夹角α 1。第二刷杆26与长度方向X之间具有第二夹角α 2。
第一刷杆24与连接杆22连接的部位为连接位置M。在图1所示的具 体实施方式中，连接位置位于第一端部122的右侧。在另一种示意性实施方式中，连接位置也可以位于第一端部122的左侧。连接位置沿着长度方向X与第一端部122形成第一距离l。刷板12在长度方向X上具有长度L。第一距离l与长度L的比例为0至1：5。当第一距离I与长度L的比例为0时，如图所示，连接位置在底板12上的正投影点与第一端部在长度方向上左边的顶点重合。
以上图1所示的示意性实施方式中，以第一端部122位于刷板12的左端为例说明。本领域技术人员可以理解，第一端部122也可以位于刷板12的右端，以适应左右手不同的刷牙习惯。
在一种示意性实施方式中，刷头设置成倾斜角度，刷牙时刷柄与牙齿形成一个角度，可以避免水顺着刷柄流到手里弄湿袖子。
在具体的实施方式中，倾角β 0的范围为0≤β 0≤60°。翘角β 1的范围为0≤β 1≤90°。第一夹角α 1的范围为0≤α 1≤35°。第二夹角α 2的范围为10°≤α 2≤90°。
如图2和3所示，在本发明的一种示意性实施方式中，牙刷进一步包括一个手持部28，其连接于第二刷杆26。连接件、第一刷杆和第二刷杆已经完成竖刷牙齿的目的。手持部28以其延长线通过刷板12的中点设置，以使牙刷形成一个平衡且美观的结构。
图4至6用于说明图2和3所示的牙刷在刷牙过程中在口腔的位置。
以图2和3所述的实施方式为例刷牙。首先如图4，需要刷门牙时，使用者拿着手持部28，将刷头10上的刷毛14放置于门牙上，连接杆22、第一刷杆24和第二刷杆26均位于口腔30的外面。使用者上下推动手持部28即可进行竖刷门牙。
如图5所示，当刷左侧的牙齿时，使用者拿着手持部28，将刷头10和连接杆22伸入左侧口腔内。这时刷头10以刷毛14贴合图中左侧牙齿 的外表面的方式置于口腔30内的左侧牙齿上。第一刷杆24和第二刷杆26位于口腔30外边。连接杆22扣在口腔30内左侧的肌肉上。使用者上下推动手持部28即可进行竖刷左侧牙齿。
如图6所示，当刷右侧的牙齿时，使用者自然地将刷头向嘴巴的图中的右侧移动，直至第一刷杆24和连接杆22一起伸入右侧的囗腔内，第二刷杆26扣在口腔30外边。口腔空间足够容纳连接杆和第一刷杆24在口腔内活动，，这时上下活动手持部28即可竖刷图中右侧牙齿。
因此在使用本牙刷的刷牙过程中，无需转动牙刷刷头，即可实现两侧牙齿的竖刷，使用十分方便。使用中牙刷能够有效清除牙缝中的食物残渣，减少牙面的磨损，并按摩牙龈防止牙龈过早萎缩。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施例的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施例或变更均应包含在本发明的保护范围之内。
