 本发明的最佳实施方式
请参见图1，一种可照明的牙科喷砂手柄，包括喷头组件1、中间组件2和尾端组件3，所述喷头组件1的下部插入中间组件2内与中间组件2可拆卸连接，且所述喷头组件1和中间组件2还通过第一定位组件连接。所述尾端组件3的上部插入中间组件2内并套接于喷头组件1的下端上，所述尾端组件3与中间组件2和喷头组件1可拆卸连接，且所述尾端组件3和中间组件2还通过第二定位组件连接。所述尾端组件3内还设有发光元件308，所述喷头组件1、中间组件2和尾端组件3上设有光传播道，所述发光元件308的光线经所述光传播道传出，以使所述牙科喷砂手柄具有照明作用。发光元件308由外接于尾端组件3的手柄尾线(内含水管、气管和电源信号线，连接手柄与主机)提供电源或控制信号。
本实施例中，发光元件308为LED灯，喷头组件1、中间组件2和尾端组件3上分别设有喷头光纤14、中间光纤22和尾端光纤307，喷头光纤14、中间光纤22和尾端光纤307均为透明导光元件，均具有导光和聚光作用。尾端光纤307、手柄光纤22和喷头光纤14端面彼此相对，形成光传播道，以最大效率进行光源的传递。
本实施例中，请同时参见图2-图4，所述喷头组件1包括管芯11、喷头12、喷头气管13、喷头光纤14、喷头连接件15和对接管16，所述管芯11设于喷头12的上端内并开设有喷口，所述喷头连接件15连接于喷头12的下端并与中间组件2连接，喷头连接件15上开设有进水孔151，喷头连接件15上位于进水孔151的上方和下方还均设有圆形密封件17，用于密封喷头连接件15与中间组件2的手柄连接件21之间的间隙；所述对接管16的一端套设于喷头连接件15的下端外，所述喷头气管13和喷头光纤14均设于喷头12内，且所述喷头气管13还经喷头连接件15延伸至对接管16内，喷头气管13的外壁和喷头连接件15的内壁之间还留有便于水流通的间隙。进一步具体的，管芯11上开设有位于管芯11中部的第一喷口111和位于管芯11外侧的第二喷口112，所述第一喷口111与设有喷头气管13的喷头12内的第一通道121连通，所述第二喷口112与喷头12内的第二通道122连通，第二通道122与喷头气管13和喷头连接件15之间的间隙连通。这一设置使得高压气与砂粉的混合气体经喷头气管13通过第一喷口111喷出，而水经喷头气管13和喷头连接件15之间的间隙通过第二通道122喷出，使得管芯11实现管芯11内部过气，管芯11外部过水，在喷头外部混合雾化，也使得外部喷出的水可包裹着砂粉，防止砂粉乱飞。
本实施例中，请同时参见图5-图7，所述中间组件2包括手柄外壳23及固设于手柄外壳23内的手柄连接件21、中间光纤22、支撑件24、水管25、分流管26和锁紧环27，手柄外壳23上设有凸台231，用于固定定位手柄连接件21。所述手柄连接件21为中空状且其上开设有出水孔211，所述喷头连接件15插入手柄连接件21的中空部内，所述中间光纤22与喷头光纤14连接，所述支撑件24支撑固定于手柄连接件21和分流管26之间，所述水管25的上端与手柄连接件21的中空部连通，所述分流管26与水管25的下端连通并套设于尾端组件3的上部(当将尾端组件3分为上部和下部时)外，所述锁紧环27与分流管26的底端端面接触且与手柄外壳23的下端内壁连接，即分流管26和手柄壳27内孔配合连接，锁紧环27起到保证分流管26的轴向固定的作用。进一步具体的，所述分流管26上设有环形槽261和卡槽263，所述环形槽261与水管25连通，所述卡槽263与尾端组件3可拆卸连接。当然其他实施例中，也可在锁紧环27上设置环形槽261和卡槽263。
本实施例中，具体的，所述第一定位组件包括凸点152和与凸点152相配合的凹槽212，所述凸点152设于喷头连接件15的侧面上，所述凹槽212设于手柄连接件21上。当凸点152旋入并拧到位时，则可以与中间组件2保持一定的角度关系保证手柄光纤22和喷头光纤14端面对齐。
本实施例中，请同时参见图8和图9，所述尾端组件3包括尾端壳316、导流阀304、卡紧环306、固定套301、对接套302、进气管303、水管接头312、尾端光纤307、发光元件308、转接件310、磁性元件311和电路板313，所述导流阀304固设于尾端壳316上并插入锁紧环27内且延伸至分流管26与分流管26连通，所述卡紧环306固定套设于导流阀304外并与卡槽263配合连接，以使中间组件2与尾端组件3实现可拆卸连接。所述固定套301固设于导流阀304上且插入手柄外壳23的中空部内，所述对接套302固设于固定套301内且套接于对接管16外，所述进气管303设于尾端壳316内且经导流阀304内部延伸至对接套302内，且进气管303与用于输入高压气与砂粉的混合流体的输入管(外接管道)连接。所述水管接头312经尾端壳316延伸至导流阀304内与导流阀304连通，所述尾端光纤307固定于导流阀304内并与中间光纤22连接。具体的，导流阀304上开设有与尾端光纤307形状相匹配的容置孔，以使得尾端光纤307通过涂胶等方式可以固定在导流阀304上。所述发光元件308通过固定于尾端壳316内的发光元件固定件309固定于尾端壳316内，所述转接件310位于尾端壳316内并与导流阀304的下端固定连接，所述磁性元件311和电路板313固定安装于转接件310上，所述电路板313上设有第一电极314和第二电极315，所述第一电极314和第二电极315均与发光元件308电连接。本实施例中，磁性元件311为磁铁，与手柄连接的主机内含有感应磁性的传感器，用于判断手柄是否拿起。
进一步具体的，所述导流阀304上还开设有第一通孔3041和第二通孔3042，所述进气管303外壁与导流阀304内壁之间留有间隙，所述第一通孔3041开设于导流阀304朝向进气管303一侧，以使导流阀304内的水通过第一通孔3041流入到导流阀304与进气管303之间的间隙，所述第二通孔3042开设于导流阀304与环形槽261的连接处，以使导流阀304与进气管303之间的间隙内的水通过第二通孔3042流至环形槽261内。
本实施例中，具体的，所述第二定位组件包括定位销305和与定位销305相配合的定位孔262，所述定位销305设于导流阀304上，所述定位孔262开设于中间组件2内的卡槽263上，以通过定位销305和定位孔262保证尾端光纤307和中间光纤22的正确连接。
可以理解，其他实施例中，发光元件也可设于喷头组件1或中间组件2内，当发光元件设于喷头组件1内时，可无需设置光纤形成的光传播道，发光元件的光线直接传出用于口腔治疗和清洁；当发光元件设于中间组件2内时，仅需在喷头组件1和中间组件2内设置光纤形成的光传播道。
本申请的工作原理为：通过外接管道输入的高压气与砂粉的混合气砂通过进气管303进入喷头气管13最终从管芯11的第一喷口111流出，与水在第一喷口111的前方混合；水则从水管接头312进入导流阀304，从第一通孔3041流入到导流阀304与进气管303之间，再从第二通孔3042流出到中间组件环形槽261后进入水管25，再从水管25流出进入手柄连接件21，从手柄连接件21的出水孔211流出经喷头连接件15的进水孔151进入喷头气管13和喷头连接件15之间的间隙(其中，圆形密封件17可保证水能从出水孔211经进水孔151进入间隙内)，最后从管芯11的第二喷口112流出，与喷头气管13出来的混合气砂混合，混合位置为与第一喷口111的前端相距3-5mm的位置处。且尾端组件3内发光元件308的光线由尾端光纤307经中间组件2的中间光纤22传导至喷头组件1中的喷头光纤14，从喷头光纤14照射出，使得所述牙科喷砂手柄具有照明作用。
本发明的实施方式
与最佳实施方式相同。
