Abstract

三头牙刷是对传统牙刷的一种改进。它由三个刷头按U字型排列,两个侧刷头设有回弹机构。刷牙时,牙齿做上下咬合运动,牙动刷不动,刷头U型开口处朝向的牙齿在U型刷头内与三个刷头的刷毛上下摩擦以达到有效刷牙目的。它有效保证了刷毛与牙齿的内、外两面必须做上下相对运动的技术要求,解决了单头牙刷技术动作不易掌握(特别对儿童而言),易造成对牙表面和牙龈的伤害缺点,使刷牙变得既容易又省时省力。

Description

三头牙刷
本实用新型涉及一种民用牙刷。
现人们使用的牙刷为单头牙刷,刷牙时需对牙的内侧、外侧和端面分别刷洗,废时废力,当对牙的内侧和外侧刷洗时,为达到刷洗效果和保护牙表面不被刷毛横向划伤,要求牙毛在牙表面上下刷动,这对许多人特别是儿童不易掌握,错误的动作常使牙毛刺伤牙龈,靠成牙龈出血,致使一些人,尤其是儿童厌倦刷牙。
本实用新型提供一种新型牙刷,它能使刷牙省时省力,容易掌握,保护牙齿和牙龈。
本实用新型的解决方案是:以常规牙刷的刷头为中心刷头1,增设两个侧刷头2和3,侧刷头2和侧刷头3分别按装在中心刷头1的左侧和右侧,使三个刷头排列成U字型。而侧刷头2和侧刷头3与中心刷头1的连接处设有回弹机构。
附图为三头牙刷示意图。
由于三头牙刷所特有的U型结构,刷牙时将三头牙刷放置在上、下牙齿之间,当牙齿咬合时,有一端的牙齿(上牙齿或下牙齿)从U型刷头的开口处进入刷毛内,此时两侧刷头因受牙齿的挤压向两侧分开,使牙齿运动至中心刷头处,并与中心刷毛接触,这样,牙齿的端面被中心刷毛刷洗,而两侧刷头因有回弹机构的作用使刷毛紧密地与牙齿两侧接触,这样,牙齿的一张一合的上下运动可使牙刷U型开口所朝向的牙齿(上牙齿或下牙齿)的三个牙面(内、外面和端面)被刷洗。由于采用三个刷头组成了U型结构,可使刷牙省时省力,并确保刷毛在牙齿两面上下刷动,提高刷牙效果,不伤害牙面和牙龈。
