超声波换能器是将输入的电功率转换成机械功率(即超声波)再传递出去的元器件，其主要部件包括盖体、压电陶瓷和电极片等。经过微观测试发现，超声波换能器的盖体部位非常容易漏电，这导致在一些有液体(例如水)的应用场合下具有十分高的安全隐患。
以洗衣机为例，洗衣机是能够对衣物进行洗涤、漂洗和甩干等的洗衣设备，为了实现对衣领、袖口等上的顽固污渍进行彻底清洗，以及为了实现对小件物品(例如眼镜等)的充分洗涤，许多洗衣机增设了超声波装置，通过超声波装置的超声波震荡作用能够实现对顽固污渍的震荡洗涤，从而消除衣领、袖口等上的顽固污渍，也能够实现对小件物品的清洗，然而，由于超声波装置的超声波换能器的盖体部位容易漏电，导致用户在使用的过程中具有触电风险，不利于用户的正常使用。
因此，本领域需要一种超声波换能器、超声波装置和衣物处理设备来解决上述问题。

基于背景技术指出的现有超声波换能器的盖体部位容易漏电，从而导致在有液的应用场合下具有高安全隐患的问题，本发明提供了一种超声波换能器，旨在避免使盖体带电，即避免盖体部位漏电，使得超声波换能器能够适应多种有液的应用场合，例如洗衣场合、手术场合和焊接场合等，降低超声波换能器的安全隐患，提升用户体验。
具体地，如图1所示，本发明的超声波换能器包括盖体1、第一压电陶瓷2、第二压电陶瓷3、正电极片4、第一负电极片5、第二负电极片6、接地电极片7、超声波震动头8、第一氧化铝陶瓷9和第二氧化铝陶瓷10，盖体1、第一氧化铝陶瓷9、第一负电极片5、第一压电陶瓷2、正电极片4、第二压电陶瓷3、第二负电极片6、第二氧化铝陶瓷10、接地电极片7和超声波震动头8依次连接，第一氧化铝陶瓷9的外轮廓大于第一压电陶瓷2的外轮廓。其中，正电极片4和第一负电极片5之间形成电磁场，正电极片4和第二负电极片6之间也形成电磁场，利用第一压电陶瓷2和第二压电陶瓷3的压电效应产生机械震动，从而使超声波震动头8发生震动。第一氧化铝陶瓷9能够防止电压击穿而使盖体1带有电荷，第二氧化铝陶瓷10能够防止电压击穿而使超声波震动 头8带有电荷，同时，接地电极提供更加有力的保障，即便有电荷向超声波震动头8移动，也会被接地电极吸收。第一氧化铝陶瓷9的外轮廓大于第一压电陶瓷2的外轮廓指的是沿部件的连接方向，第一氧化铝陶瓷9相对于第一压电陶瓷2向外延伸一部分，即如果第一压电陶瓷2向第一氧化铝陶瓷9投影，投影的部分全部在第一氧化铝陶瓷9内，这样设置的好处在于电磁场的电荷不会跨绕过第一氧化铝陶瓷9而使盖体1带电，从而保证盖体1不会带电而发生漏电情况。在实际应用中，第一压电陶瓷2可以为圆盘状，还可以为其它形状，第一氧化铝陶瓷9可以为圆盘状，当然，第一氧化铝陶瓷9还可以为方块状等其它情况，本领域技术人员可以在实际应用中灵活地设置第一压电陶瓷2和第一氧化铝陶瓷9的形状，只要保证第一氧化铝陶瓷9的外轮廓大于第一压电陶瓷2的外轮廓即可。
优选地，第二氧化铝陶瓷10的外轮廓大于第二压电陶瓷3的外轮廓。与前述类似地，第二氧化铝陶瓷10的外轮廓大于第二压电陶瓷3的外轮廓指的是沿部件的连接方向，第二氧化铝陶瓷10相对于第二压电陶瓷3向外延伸一部分，即如果第二压电陶瓷3向第二氧化铝陶瓷10投影，投影的部分全部在第二氧化铝陶瓷10内，这样设置的好处在于电磁场的电荷不会跨绕过第二氧化铝陶瓷10而使超声波震动头8带电，从而保证超声波震动头8不会带电，通过第二氧化铝陶瓷10和接地电极的组合，能够保证超声波震动头8始终不带电，即便将超声波震动头8伸入到有液的环境中，也不会发生触电情况，极大地降低安全风险。在实际应用中，第二压电陶瓷3可以为圆盘状，还可以为其它形状，第二氧化铝陶瓷10可以为圆盘状，当然，第二氧化铝陶瓷10还可以为方块状等其它情况，本领域技术人员可以在实际应用中灵活地设置第二压电陶瓷3和第二氧化铝陶瓷10的形状，只要保证第二氧化铝陶瓷10的外轮廓大于第二压电陶瓷3的外轮廓即可。
优选地，超声波换能器还包括螺接件，超声波震动头8朝向接地电极片7的一侧设置有螺纹沉孔，螺接件依次穿过盖体1、第一氧化铝陶瓷9、第一负电极片5、第一压电陶瓷2、正电极片4、第二压电陶瓷3、第二负电极片6、第二氧化铝陶瓷10和接地电极片7并与螺纹沉孔连接。其中，可以在盖体1、第一氧化铝陶瓷9、第一负电极片5、第 一压电陶瓷2、正电极片4、第二压电陶瓷3、第二负电极片6、第二氧化铝陶瓷10和接地电极片7的中部都设置通孔，在超声波震动头8的中部设置螺纹沉孔，通过螺接件将所有部件相连，螺接件可以为螺钉、螺栓或螺柱。
在另一方面，如图2所示，本发明还提供了一种超声波装置，超声波装置包括外壳、容水构件200、安装构件300和上述的超声波换能器100，容水构件200和安装构件300均与外壳滑动连接，盖体与安装构件300连接，超声波震动头位于容水构件200的上方。容水构件200和安装构件300都能够相对于外壳滑动，安装构件300相对于外壳滑动的过程中能够带动超声波换能器100也相对于外壳滑动，超声波换能器100能够向容水构件200中发射超声波，具体为超声波震动头向容水构件200中发射超声波，用户可以将物品放入到容水构件200中进行超声波洗涤。在上述中，容水构件200可以为容水箱、容水盘或容水盒等，安装构件300可以为安装架、安装板或安装座等。本领域技术人员可以在实际应用中灵活地设置容水构件200和安装构件300的具体结构，只要通过容水构件200能够容纳水，通过安装构件300能够将超声波换能器100进行安装即可。
优选地，如图3所示，安装构件300上连接有能够将超声波换能器100包覆的防护罩400，防护罩400上形成有允许超声波通过的通口。防护罩400能够对超声波换能器100进行防护，防止超声波换能器100受到外力冲击，防护罩400上形成的通口能够允许超声波通过，从而使得超声波震动头发出的超声波能够到达容水构件200。防护罩400和安装构件300可以采用螺接的方式连接，还可以采用卡接的方式连接。在一种优选的情形中，防护罩400与安装构件300通过卡扣连接，从而便于防护罩400的拆卸、维修和更换。
在又一方面，本发明还提供了一种衣物处理设备，衣物处理设备包括箱体、设置在箱体上的盘座和上述的超声波装置，箱体和/或盘座上形成有容纳腔室，外壳设置在容纳腔室中，容水构件和安装构件都设置为能够被拉出容纳腔室外以及被推入容纳腔室内。其中，容纳腔室可以只形成在箱体上，也可以只形成在盘座上，当然，还可以一部分形成在箱体上，另一部分形成在盘座上，容纳腔室可以形成在箱体或盘座 的外侧壁上，还可以形成在箱体或盘座的其它位置，以波轮洗衣机为例，波轮洗衣机的盘座上形成有衣物投放口，衣物投放口位于波轮洗衣机的内筒和外筒的上方，容纳腔室可以形成于衣物投放口的后侧壁上，也就是说，当超声波装置从容纳腔室中拉出时，超声波装置位于内筒和外筒的上方。当然，衣物处理设备还可以为滚筒洗衣机、滚筒洗干一体机等。需要说明的是，本发明的衣物处理设备采用超声波装置时超声波装置可以对衣物的局部进行预洗，预洗之后的衣物可以选择投入衣物处理筒中通过常规衣物处理程序进行进一步衣物处理，当然，超声波装置还可以对眼镜、首饰、口罩和领带等小件物品直接进行超声波洗涤，超声波洗涤之后可以直接完成洗涤，无需再次投入到衣物处理筒中进行进一步衣物处理。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
