所述气动薄膜开关， 由环状隔离层 1 321隔离两层宽度与环状隔离层 1 321对 应的薄膜环 322， 两层薄膜环均向环心方向设置凸出叶片 323， 对应两凸出叶片 323之间的如图 3接触和如图 1分离， 构成气动薄膜开关开合。
如图 4两凸出叶片 323之间靠近环心的端头， 固定隔离层 II 324。 两凸出叶 片 323没有隔离部分如图 4接触， 如图 5分离， 构成气动薄膜开关开合。
如图 6环状隔离层 1 321隔离的两层薄膜环的环宽大于环状隔离层 I 321的环 宽， 在两层薄膜环上沿环状隔离层 I 321内侧向环心方向设 T形切缝 325， 相邻 两个 T形切缝 325之间， 构成凸出叶片 323。 环状隔离层对应的部位是薄膜环 322。
所述的齿科涡轮钻， 在出气通道上固定环状单向阀， 如图 7， 所述环状单向 阀是环状伸缩弹性膜 41， 自然状态下环状伸缩弹性膜 41中心孔抱紧车针， 图中 只抱紧车针， 也可以把涡轮轴加长， 抱紧涡轮轴， 如图 8工作状态下环状伸缩 弹性膜 41中心孔吹离车针。 当然也可以吹离涡轮轴。
所述环状伸缩弹性膜 41是柔软硅橡胶、 聚氨酯、 乳胶或者普通橡胶之一。 环状伸缩弹性膜 41的厚度为几十微米至两毫米左右。
所述环状伸缩弹性膜 41下表面的一部分自然状态下与机头 LED灯座 51上 表面分离， 如图 9出气状态下该部分与机头 LED灯座 51上表面接触， 环状伸 缩弹性膜 41下表面部分与机头 LED灯座 51上表面接触的部位的接触和分离构 成开关。 这种情况下， 环状伸缩弹性膜是导体， LED灯座上表面是导体。
所述环状伸缩弹性膜下表面设置导体 52，如图 10是环状伸缩弹性膜下表面 视图， 导体 52向环心呈放射状分布并在环状伸缩弹性膜 41外边缘环状连接， 机头内 LED灯座上表面部位设置导体。 导体 52部位对应的环状伸缩弹性膜厚 度厚， 形成凸起； 未设置导体 52的部位厚度薄， 形成凹槽 54。
如图 11， 所述环状伸缩弹性膜 41下设置环状按压薄膜开关 61。
如图 12-14， 环状按压薄膜开关是指： 上下两个薄膜环 611之间设置两个隔 离片 612， 薄膜环 611没有隔离片 612的部位受压接触、 自然状态分离构成按压 薄膜开关。
如图 13所述弹性膜 611中心孔周围厚度厚， 形成环状台圈 411， 该环状台 圈 411外侧设置厚度小于环状台的压块 412， 环状台圈与压块之间上部连接， 压 块 412对应环状薄膜开关未设置隔离点的部位。 工作时， 气流压力把压块 412 压下， 使得两层弹性环接触导通； 停止工作时， 压块 412 自行抬起， 两层弹性 环 611分离， 开关断开。
如图 1， 所述 LED灯和开关设置在机头部位， 电源部件至少部分设置在机 头部位。 减少了部件之间的链接路径， 就简化了制造工艺， 缩小了一次性部件 的体积。
如图 15， 所述电源是设置在机头内的环状电池 511。
如图 16， 所述电源是设置在机头颈部一侧的纽扣电池 512， 索尼 337纽扣 电池。
如图 1， 所述电源是设置在机头颈部一侧的针管电池 513。 208号针管电池 也叫鱼漂电池， 208号指直径 2mm长度 8mm。
如图 1， 所述涡轮钻是按压牙钻， 机头盖 182的材料是橡胶性质， 橡胶性质 机头盖被卡箍 183卡紧密封接机头壳壁 181上部， 上轴承座 11螺紋固定在机头 壳壁 181形成的腔体内。
所述橡胶性质机头盖是硅橡胶、 聚氨酯、 乳胶或者普通橡胶之一。
所述的齿科涡轮钻， 如图 1 是按压涡轮钻， 其车针按压夹持机构为： 涡轮 轴 281中心孔 211设置一段锥形孔 212， 涡轮轴中心孔 212内设夹爪 213， 夹爪 213沿涡轮轴轴向是与锥形孔配合的锲形，夹爪 213上部与连接杆 214固为一体， 连接杆 214上部伸出涡轮轴中心孔 211与弹簧挡板 215固为一体，连接杆外 214 的弹簧挡板 215与涡轮轴 281之间设弹簧 216， 涡轮轴 281、 夹爪 213、 连接杆 214和弹簧挡板 215均为塑胶件。所述夹爪， 与现有按压牙钻的三瓣簧的簧瓣作 用相似， 塑胶件的优点是： 由于塑胶的刚性低， 受压后， 塑胶件的形状就有所 改变， 这种改变增加了车针、 楔块、 风轮轴、 内孔三者之间的接触面积和摩擦 力， 当楔块断裂时， 不容易出现飞针。
所述弹簧挡板 215是惯性盘。 所述惯性盘， 就是比现有的弹簧挡板直径大， 就增加惯性盘， 旋转时转动惯量大， 切削时能保持大的转速并且转速稳定。
所述弹簧是蝶簧或者板簧之一。 蝶簧或者板簧同样增加转动惯量。
如图 16所述蝶簧或者板簧相对扣合叠加设置。 这样设置增大按压行程。 所述蝶簧如图 17是槽型蝶簧， 所述板簧如图 18是槽型板簧。
所述夹爪夹紧车针时， 涡轮轴中心孔上端与下端连通。 所述涡轮轴中心孔 上端与下端连通， 指气流从涡轮轴中心孔上端能够通到下端， 这种情况， 车针 夹紧时， 只要涡轮轴锥形孔部分不密闭就能从部件之间的间隙连通。
所述的齿科涡轮钻， 如图 19， 连接杆与涡轮轴中心孔之间设置密封圈 217; 上出气通道上设置与回气通道连通的回气通道 11151。 （回气通道 II在颈部与回气 通道连通， 设置回气通道 II是为了给上轴承降温。 本实施例， 回气通道 II通入手 柄内、 进气通道管和喷水通道管外的空间， 回气通道也进入该空间。
如图 19， 在下出气通道上设置下喷水孔 161。
如图 1在上下两个出气通道上设置上喷水孔 162和下喷水孔 161，也可以只 设置上喷水孔 162。 下出气通道的喷水孔喷出的水， 被腔体喷出的气流雾化， 随 涡轮轴或者车针旋转排出， 能够充分雾化并冷却车针。 同时， 缺少了专用雾化 水汽的喷气通道， 而现有的专用雾化水汽的通道与供涡轮旋转的供气通道相互 连通， 缺少专用雾化水汽的喷气通道， 避免了该喷气通道的回吸； 再者， 喷水 口在上出气通道上， 由于上盖密封， 水和气流由蝶簧或者板簧与涡轮轴和惯性 盘之间的间隙进连接杆与涡轮轴内孔之间的间隙， 然后通过楔块之间的间隙进 入下出气通道喷出机头。 在这个过程中， 水谁被充分雾化。 这种情况， 喷水量 就可以加大； 而且， 水通过涡轮轴中心孔内部件之间的间隙， 都能够喷向车针。
如图 1、 19、 20、 21， 上喷水孔 162及下喷水孔 161设置在机头壳壁内和手 柄颈部。 喷水通道在机头壳壁内， 可以由三维成型设备实现。 这个实施例是在 管壁内， 但是现有的三点喷雾或者多点喷雾牙钻， 是在下轴承座下设置环状通 道， 该环状通道连通喷水通道和专用雾化水的喷气通道， 水和气在该环状通道 雾化后， 由设置在车针周围的喷雾口喷出， 例如： 申请号 200910151521.6， 发 明名称 "一次性喷雾高速涡轮牙科手机"的中国发明专利申请。 这种结构中， 专用雾化的喷水通道是多余的， 不设该通道， 水由喷雾口排出后， 由于下出气 通道喷出的是高速气流， 在车针周围形成负压， 负压将水吸入高速气流， 就自 然雾化。 这种方式利用了下出气通道气流， 同样是本专利的保护范围， 是本发 明实施例； 将该环状通道的水直接进入下出气通道， 也是本发明实施例。
所述的齿科涡轮钻， 如图 22-25手柄内是沿手柄轴向设置的网格通道 165， 网格通道 165与机头及手柄插头对应的通道分别连通。 手柄内设置的网格通道， 不但起到支撑作用， 而且作为手柄内通道使用， 相同截面积、 相同数量通道的 情况下， 网格通道利用率最高， 也就是每个网格通道的截面积最大。 而且通道 可以设置很多， 为牙钻增加其他功能预留了通道。
网格通道 1651是进气通道，该网格通道 1651在手柄颈部伸出进气管道 1652 与如图 2机头的进气通道 14连通， 在手柄尾部伸出进气管道 1653与手柄插头 进气通道连通； 网格通道 1656是进水通道， 该网格通道 1656在颈部伸出进水 管道 1657与如图 1机头的进水孔 161、 162连通，在手柄尾部伸出进水管道 1658 与手柄插头进水通道连通； 机头回气通道 15通过颈部手柄内空腔 166与其它网 格通道连通， 这些网格通道通过尾部手柄内空腔 167与插头回气通道连通。 所 述网格通道在手柄颈部伸出进气管道与机头的进气诵 i首谇诵. i玄讲钶昝憎 AA M 更正页 （细则第 91条) 格通道伸出部位， 其形状与网格通道一致。 该进气管道与机头进气通道连通部 位， 其形状与进气通道一致。 比如 ί 网格通道是菱形， 进气通道是圆形， 那么， 该进气管道形状从菱形渐变为圆形。
