具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。
图1是超声波发生器的结构图；包括螺栓1、前盖7、绝缘套3、第一换能4、第二换能片6、正极电极片5、负极电极片9和后盖2，通过螺栓依次将后盖、绝缘套、第一换能片、正极电极片、第二换能片、负极电极片和前盖连接为一体，且同心设置。后盖、第一换能片、正极电极片、第二换能片和负极电极片的直径相同；所述前盖包括喇叭口部和端口部，所述喇叭口部的剖面呈等腰梯形，所述喇叭口部的小端部的直径与后盖直径相同。
其结构尺寸和大小都是根据所设计的功率并经过大量实验确定的。后盖、第一换能片、正极电极片、第二换能片和负极电极片的直径及材料都是特别根据功率来设计的。目前使用得最多的是60W的超声波发生器，其前盖的大端部的直径为48mm，高度为24mm；所述后盖的的直径为38mm,高度为11mm，第一换能片和第二换能片的高度相同为5mm；正极电极片和负极电极片一般采用磷铜材料，绝缘套采用聚四氟乙烯材料制成。如果将超声波发生器直接固定在不锈钢槽体的底部，如果直接将前盖直接使用粘胶粘贴在不锈钢槽体1的底部，可能 带来以下问题：不锈钢槽体及不锈钢槽体上增加的水等重量将形成负载直接叠加在超声波发生器上，其容易带来超声波发生器负载变化敏感的问题，造成超声波频率发生漂移和抖动的问题，并进而引起发热的问题；同时直接接触还存在一定的安全隐患。为了解决该问题需要在不锈钢槽体与超声波发生器之间增加一个垫片8，一般选用绝缘片，绝缘片略大于前盖的端面直径,如选择直径为53mm的即可。固定超声波发生器的方法是采用粘胶将绝缘片和超声波发生器进行粘接，之后再将绝缘片通过粘胶压接在不锈钢槽体的底部，该连接工艺要求不锈钢槽体的连接部的平整度非常高，为了保证其平整度，需要额外在安装超声波发生器的部位压一个圆形凹面，因为小面积更容易实现其平整度。
图3是改进后的大功率超声波发生器的结构图，为了将超声波发生器的功率提高到90W,除了将超声波发生器的驱动电路参数上调外，还需对超声波发生器也就是振头部分重新进行选材和结构尺寸匹配。经过大量的实验验证，选定如下结构匹配的振头尺寸可以较好的实现90W的功率输出的要求。将后盖、第一换能片、正极电极片、第二换能片和负极电极片的直径调整为44～46mm；前盖的喇叭口部的小端部的直径与后盖直径相同，大端部的直径调整为54～56mm，整体高度为23.5～24.5mm；端口部上还设有的环形凹槽；后盖的高度为10.5～11.5mm,第一换能片和第二换能片的高度相同为4.5～5.5mm。优选后盖的高度为10.8～11.2,后盖的直径为44.8～45.2mm；前盖的端口部直径为54.8～55.2mm，前盖整体高度为23.8～24.2mm；第一换能片高度为4.8～5.2mm。
同时将绝缘片替换为铝片，同时加大铝片的面积；圆形铝片的直径调整为前盖的端口部直径的1.3～1.7倍，如前盖的端口部直径为55mm时，对应将圆形铝片直径调整为直径85mm,相当于将超声波发生器与不锈钢筒体之间的连接面积扩大为原来的2.3倍左右。由于改为铝片后超声波发生器、铝片和不锈钢筒体都是金属材料，因此胶接效果更佳；同时扩大铝片的面积，增加铝片与不锈钢筒体之间的连接面积，同样加强了胶接强度。铝片的导热性能非常好，超声波发生器工作产生的热量可快速通过铝片传导导入不锈钢筒体，相当于不锈钢筒体整个都是超声波发生器的散热片，可快速将超声波发生器产生的热量快速的散发出去，降低了超声波发生器温升过高的概率，也大大降低了连接的粘胶的因为温度过高引起的脆化，进而产生掉头的问题。
以上所揭露的仅为本实用新型一种实施例而已，当然不能以此来限定本权 利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本实用新型权利要求所作的等同变化，仍属于本实用新型所涵盖的范围。
