Description

新型电动牙刷
本实用新型涉及了一种新型电动牙刷,特别适用于特殊形状刷毛板正反转摆动式的新型电动牙刷。
目前现有技术的摆头电动牙刷,其减速传动原理采用主动轮,被动轮,再通过连杆,摆杆带动输出轴的曲柄连杆传动机构。此机构有一大缺点,即其摆动输出轴摆角最大只能到70°左右。
本实用新型的目的在于提供一个输出轴摆角可大于360°从而使牙刷头获得很大的正负转角,并高速旋转,大大提高电动牙刷的刷牙效率。本实用新型的目的是通过如下的技术方案来实现的:本实用新型由牙刷头16传动机构17,开关组件18,电机13,电池19,壳体20,尾盖21等组成,传动机构17中电机13的主轴上主动齿轮12带动被动齿轮11,被动齿轮11上的偏心轴带动一连杆齿条14作往返运动,连杆齿条14在运动中与被动齿轮11相啮合;摆动传动轴8通过中心摆杆7与摆动块5相连,摆动块5上有一个金属摆动球杆3,摆动球杆3拨动刷毛板4的U型金属镶片1。本实用新型的电机13通过本实用新型的传动机构使传动轴得到正反高速旋转,每分钟3600次数,此传动轴传给牙刷头中的相应摆杆,使刷毛板作高速正反摆动,而且输出轴的摆角可大于360,从而达到高效刷牙的目的。
本实用新型与现有技术相比,具有获得高速旋转,并很大的正反转角等优点。
本实用新型的附图说明如下:
图1是本实用新型的结构示意图。
图2是本实用新型的传动机构原理图。
图3是本实用新型的牙刷头传动原理图。
下面结合附图对本实用新型作进一步详细的描述:如图1所示,本实用新型由牙刷头16,传动机构17,开关组件18,电机13,电池19,壳体20,尾盖21等组成。如图2所示,本实用新型的传动机构17中电机13的主轴上主动齿轮12带动被动齿轮11,被动齿轮11上的偏心轴带动一连杆齿条14作往返运动,连杆齿条14在运动中与被动齿轮11相啮合,连杆齿条14上有两个压爪a和b压向正反转齿轮15的轴,使该齿轮轴在正反旋转的同时,又在压爪a,b内滑动,以使该被动齿轮11在运行中不会脱离齿条。这样就使摆动传动轴8得到一个平稳而可靠的正反摆动运动,该运动又传给牙刷头16使得牙刷头16的刷毛板4获得一个下反旋转摆动。摆动传动轴8通过中心摆杆7与摆动块5相连,摆动块5上有一个金属摆动球杆3,摆动球杆3拨动刷毛板4上的U型金属镶片1,从而使刷毛板4作高速正反摆动。如图3所示,由于刷毛板4是特殊形状,刷毛板4上的中心轴2与大头外园部份是同轴的,所以刷毛板4的大头部份做园刷头运动。而刷毛板4的小头部份又远离中心轴,那么小头部份的刷毛做近似的上下摆动(相当一个摆头的电动牙刷)从而使这种电动牙刷具有一个综合性能,并且刷牙效率特别高。
