附图说明
图1为本发明的结构示意图；
图2为恒定功率输出电路电路图；
图3、图4为工作头的结构示意图。
具体实施方式
以下结合附图对本发明的原理和特征进行描述，所举实例只用于解释本发明，并非用于限定本发明的范围。
如图1所示，一种超声牙科除垢装置，其包括主机、手柄和连接在手柄上的工作头；手柄内设有压电陶瓷换能器；工作头采用TC4钛合金材料制成；工作头的连接部与压电陶瓷换能器的机械输出端相连接；主机内设有为压电陶瓷换能器提供电能的恒定功率输出电路，恒定功率输出电路通过电能传输的尾线与手柄连接，具体是与手柄内压电陶瓷换能器的输入端电连接，压电陶瓷换能器再将电能转换为机械能传递给工作头。
如图2所示，下面对恒定功率输出电路作进一步说明：
恒定功率输出电路包括电源输出电路、采样电阻R1和超声变压器T1；电源输出电路包括稳压芯片U1和电感L1，稳压芯片U1的1号引脚连接至外部电源，稳压芯片U1的2号引脚通过电感L1连接至超声变压器T1的输入端，稳压芯片的3号引脚和5号引脚分别与地连接，稳压芯片的4号引脚通过采样电阻R1接地，超声变压器T1的输出端通过采样电阻R1接地；电源输出电路，其用于由稳压芯片U1的输出端通过电感L1为超声变压器T1提供电源，并根据超声变压器T1输出端的反馈电压实时调整其输出电压；采样电阻R1，其用于获取超声变压器T1输出端的反馈电压并反馈给电源输出电路的电压反馈端；超声变压器T1，其通过OUT引脚对压电陶瓷换能器供电，根据电源输出电路的输出电压调整其输出端的反馈电压。
进一步：电源输出电路还包括电容C1，电容C1的正极连接至稳压芯片的1号引脚，负极与地连接。电容C1用于对外部输入电源进行滤波，以确保稳压芯片的输入输出信号稳定。
进一步：电源输出电路还包括用于对稳压芯片U1的输出电压进行滤波的电容C2，电容C2的正极与超声变压器的输入端连接，负极与地连接。
进一步：电源输出电路还包括用于续流的二极管D1，二极管D1的正极与稳压芯片U1的2号引脚连接，负极与地连接。二极管D1用于当稳压芯片输出高低电平时续流。
本实施例中，设定：超声变压器的输入端电压为Vs，超声变压器的输出端的采样电压为Vref，超声变压器T1的阻抗为ZT1。
具体地，根据超声变压器T1处的电压关系可以推导得到Vs＝Vref(1+ZT1/R1)，式中超声变压器T1的输出端的采样电压Vref可以认为恒定值，R1为恒定电阻，由此可知，Vs会随着超声变压器T1的阻抗ZT1的变化 而变化。当超声波洁牙机工作时会遇到外部阻力，此时，超声波洁牙机的输出功率变小，由于输出端电压Vref恒定，超声变压器T1的阻抗ZT1增大，则超声变压器输入端电压Vs增加，相应地，超声变压器T1的输出功率增加；同理，相反地，当超声波洁牙机输出功率变大时，超声变压器T1的阻抗ZT1变小，超声变压器T1输入端电压Vs减小，相应地，超声变压器T1的输出功率减小。通过上述方式可使超声波洁牙机的输出功率趋于稳定值，即超声波洁牙机的输出功率可稳定在设定值处保持恒定。
稳压芯片U1采用LM2576开关型集成高效稳压电路，并具有完善的保护电路，包括电流限制及热关断电路等，最大输出电流为3A，最高输入电压为40V，提供3.3V、5V、12V及可调等多个电压，功耗较低，转换效率较高。
如图3、图4所示，下面对工作头作进一步说明：
工作头包括与洁牙机手柄连接的连接部4、与连接部4连接的颈部3和工作时与牙齿接触的头部1，头部1与颈部3之间通过弧度为60度到180度(图4中的&3)的弯部2连接；颈部3包括至少两个弯曲部。本例中多个弯曲部，主要用于减小整个工作头的硬度，增加整个工作头的柔和度，使得整个工作头具有弹性。
进一步：连接部4、颈部3、弯部2和头部1一体成型，且采用钛合金制成。钛合金制备的工作头硬度低，振幅小，弹性好，临床效果大幅度提升，大幅度减小给治疗的患者带来疼痛不适的感觉，大大提高患者治疗时的舒适度。
进一步：头部1远离颈部3的一端设有球状或半球状结构11。最好球状或半球状结构11的直径取值范围为0.1到3毫米。球状或半球状结构11的 表面上可以设有镀金刚砂。这样设计可以使得工作效率更高。
进一步：连接部4上开设有多个方便装卸的内凹扳手位41，多个内凹扳手位41两两相对设置，本实例中连接部4可以设有二、四或六个。
进一步：头部1的尖端与颈部3的轴线之间的距离L3为3到30毫米。
进一步：本实例中弯曲部设为两个，分别为第一弯曲部31和第二弯曲部32；第一弯曲部31的一端与连接部4连接，第一弯曲部31的另一端与第二弯曲部32的一端连接；头部1与第二弯曲部32的另一端之间通过弯部2连接。
上述中的第一弯曲部31和第二弯曲部32相关参数可以做如下限定：
1、第一弯曲部31的弧度&1为90度到180度；
2、第二弯曲部32的弧度&2为90度到180度；
3、第一弯曲部31的半径R1为1至50毫米；
4、第二弯曲部32的半径R2为1至50毫米；
5、第二弯曲部32中心线的拐点处(拐点为：第二弯曲部2的中心线上离颈部4的轴线最远的一点)与颈部3的轴线之间的距离L1为0.5到20毫米；
6、弯部2中心线的拐点处(拐点为：弯部2的中心线上离颈部4的轴线最远的一点)与上述第二弯曲部32中心线的拐点处的距离L2为0.5到20毫米。需要注意此处两拐点之间的距离为附图中表示的距离，并不是两拐点之间连线的距离。
采用上述数据主要是为了满足人体口腔的形状、牙齿的布局，而做的调整，方便对牙齿进行洁治，具体数据对工作头工作的性能不会产生实际的影响。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
