本发明涉及电动牙刷领域，尤其涉及一种竖刷电动牙刷。
 背景技术
目前市面上有两种电动牙刷，第一种是在牙刷的刷毛平面内摆动的机械式回转轮转动牙刷，它包括悬臂梁自由端高速旋转振动而撞击回转轮方式，高速旋转凸轮、偏心轮或曲柄撞击回转轮方式工作原理的粗放式平面机械传动机构，其回转平面是平行于牙齿表面，无法清理牙龈齿沟，而且对牙面磨损大。第二种是振动式牙刷，包括机械偏心轮振动和线性电磁偏转加强型激振电动牙刷，振动是按周期呈指数衰减的，刷毛振幅看起来很大，但是刷毛的质量是毫克数量级的，实际用来刷牙的输出功率很低，刷牙效果并不理想。
 技术问题
研发出牙刷臂摆动的竖刷电动牙刷一直是电动牙刷的难题。用正反转电机驱动牙刷臂摆动的竖刷电动牙刷是最朴素的思维，电机有两个时间常数，机械时间常数Tm和电气时间常数Te，而且Tm远远大于Te，也就是说小角度正反转电机的频率会很低，输出的扭矩会很小，并且会在强电流条件下工作，尤其是电动牙刷允许布置电机的尺寸空间非常有限。
 技术解决方案
本发明所要解决的技术问题是提供一种竖刷电动牙刷。
本发明解决上述技术问题所采取的技术方案如下：

优选的是，所述滑块限位圆筒6底端设有安装柱，所述法兰环上开设有安装孔，所述安装柱位于法兰环的安装孔内。滑块限位圆筒6通过安装柱与主支架3固定连接，通过安装柱限制滑块限位圆筒6的自由度。
优选的是，所述滑块4为扇形。扇形结构体积更小。
 有益效果

以下将结合附图及实施例来详细说明本发明的实施方式，借此对本发明如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本发明中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本发明的保护范围之内。
如图1-9所示，一种竖刷电动牙刷，包括刷头9和壳体，壳体内固定有电机1和输出轴，输出轴穿透壳体与刷头9连接，所述输出轴和电机1之间设有变速器，变速器包括正置凸轮2、主支架3、滑块4、滚球5、滑块限位圆筒6、反置凸轮圆筒7和变速器外壳8，所述正置凸轮2为圆筒状，所述正置凸轮2外壁设有凹槽21，所述凹槽21绕正置凸轮2首尾相连，所述凹槽21内设有滚球5，所述主支架3套设在正置凸轮2外，所述主支架3底端设有法兰环，所述法兰环上开设有限位孔31，所述主支架3侧壁设有滑块槽32，所述滑块槽32内设有滑块4，所述滑块4外壁设有圆柱销42，所述滑块4内壁上设有弧面槽41，所述弧面槽41与滚球5抵接，所述滑块限位圆筒6套设在主支架3外，所述滑块限位圆筒6与主支架3固定连接，所述滑块限位圆筒6纵向设有贯通槽61，圆柱销42贯穿所述贯通槽61，所述反置凸轮圆筒7套设在滑块限位圆筒6外，所述反置凸轮圆筒7侧壁上设有滑槽72，所述圆柱销42位于滑槽72内，所述反置凸轮圆筒7底端设有限位凸块71，所述限位凸块71位于法兰环的限位孔31内，所述变速器外壳8套设在反置凸轮圆筒7外。
优选的是，所述输出轴与反置凸轮圆筒7一体，所述输出轴穿透变速器外壳8。
优选的是，所述滑块限位圆筒6底端设有安装柱，所述法兰环上开设有安装孔，所述安装柱位于法兰环的安装孔内。滑块限位圆筒6通过安装柱与主支架3固定连接，通过安装柱限制滑块限位圆筒6的自由度。
优选的是，所述滑块4为扇形。扇形结构体积更小。
设正置凸轮的凹槽单位转角的轴向位移为t，t>0时为升程，t=0 时为无升程圆环槽，t<0时为回程。三种情况对应的转角值与单位升程的不同组合可以得到不同的预期凹槽21。当凹槽21的全部180度转角设计为单一升程或回程时，可以得到最大的扭矩增大倍数。设计反置凸轮圆筒7的滑槽72，如果滑槽72的转角设定为θ，正置凸轮的多圈凹槽21的圈数为k，则扭矩放大倍数m=k*180/θ，输出频率为输入频率除以k。比如单圈凹槽正置凸轮，反置凸轮圆筒的滑槽72转角设定为10-18度，则最大扭矩放大倍数为18-10倍；若是多圈凹槽21，则最大扭矩放大倍数再乘以圈数k。
  本变速器为精密空间传动机构，电动机驱动正置凸轮2旋转，正置凸轮2上的凹槽21曲面推动滚珠，滚珠在凹槽21内循环运动，滚珠与滑块4配合，在滑块限位圆筒6的贯通槽61的限制下，滑块4作直线往复移动，滑块4上的圆柱销42位于反置凸轮圆筒7的滑槽72内，圆柱销42拨动反置凸轮圆筒7摆动转动，刷头9套设在反置凸轮圆柱上，实现竖刷。
正置凸轮2的凹槽21对应正置凸轮2中心轴圆周转角为360度的整数倍，正置凸轮2旋转一周对应滑块4往复运动一个周期，这种正置凸轮的凹槽21称为单圈循环，依此类推多圈循环。多圈循环的凹槽21每360度会在升程和回程曲线上产生一个单点不连续的交叉断点，在摩擦力和惯性的作用下，滚球5可顺利通过交叉断点。无拐点的曲线凹槽21使这正置凸轮2可以稳定工作。
主支架3，滑块限位圆筒6，变速器外壳8。先后装配，彼此固定连接成一体。支架部分是耦合正置凸轮2、反置凸轮圆筒7和滑块4的关键部件，通过反置凸轮圆筒7的限位凸块71加强反置凸轮圆筒7的强度，通过限位凸块71与限位孔31的配合，限制反置凸块圆筒的摆动幅度，主支架3在输入端与电机1联接，根据需要可以开切口或者增设卡扣等辅助机构等。
滑块4和滚珠配合，正置凸轮2通过滚珠与滑块4耦合。通过滑块4上的圆柱销42，滑块4驱动反置凸轮圆筒7。滑块4采用扇形结构，体积最小，也可以采用其他台阶定位导向或其他形状，滚珠可以采用其他其他滚子，圆柱销42也可以采用锥销、球头销、伸缩销等其他等效部件。
反置凸轮圆筒7是变速器的输出端，其上套装刷头9执行竖向摆动刷牙。如果作为功能性变速器，反置凸轮圆筒7的滑槽72可以设计成0-360度任意固定角度。作为电动牙刷输出端，滑槽72角度在10-18度比较符合工况要求。反置凸轮圆筒7的滑槽72是滑块4的圆柱销42相配合，对于电动牙刷所使用的小转角滑槽72，可以直接里外壁开通以简化加工工艺，不会对反置凸轮圆筒7刚度产生很大影响。
本发明基于传统永磁直流旋转电机提供动力，电机转速3000-12000转/分钟，电机输出扭矩6-18 g.cm，经过该机械变速器的运动转换，实现固定在输出端的牙刷刷头随输出轴在10-18度的任何一个固定设计角度参数范围内往复摆动，在单圈凹槽21的情况下，摆动频率与电机输出角速度相等，约为3000-12000次/分钟，刷毛摆动弧长在2.5-4.5毫米，扭矩增大最大倍数为10-18，10度时为18倍，18度时为10倍，改变正置凸轮凹槽21的曲线设计可以减少扭矩倍增系数，实现力矩输出约50-160 g.cm设定数值。
本实施案例中变速器的正置凸轮是主动件，反置凸轮圆筒是从动件，根据实际使用情况，当滑槽72为360度封闭循环时，可将反置凸轮圆筒作为主动件，正置凸轮为从动件。
本发明一种竖刷电动牙刷，通过在电机1与输出轴之间加设变速器，实现电动牙刷的刷头9绕轴线方向往复摆动，本发明在正置凸轮2上开设有无拐点循环曲线凹槽21，保证电机1的均速转动输出，在有限的空间内，输出扭矩更大，当凹槽21为单圈时，电机1转动一周，刷头9摆动一个周期，刷头9摆动频率与转动角速度相同。
