随着人们对健康保健要求的逐步提高， 对蔬菜水果的表面污物， 残留农药 的杀菌、 清除越来越受到重视。 为此， 市场上产生了一种蔬菜水果清洗器， 简 称洗菜机， 该洗菜机就是为满足人们的这方面需求。
现有的洗菜机的清洗方法是， 蔬菜水果放置在洗菜筐内， 洗菜机的电机带 动洗菜筐在盛水桶内转动， 依靠洗菜筐转动时产生水流， 对果菜进行冲洗， 以 达到清洗目的。但洗菜筐转动的清洗方式仅是能够清洗果菜的表面污物和泥土， 对蔬菜水果表面的细菌和农药的作用不明显。 为了弥补这方面的不足， 洗菜机 上配置有臭氧发生器， 期望起到对蔬菜水果表面的杀菌和对农药的降解作用。

可见， 本发明的安装支架 1 5与安装孔 3-1 的结构形式， 可以将等离子发 生器集装在安装支架上， 产生的等离子可以大面积地与洗涤水交流， 有利于杀 菌和消灭水中的病毒， 也有利于装配批量生产， 提高生产效率。
等离子驱动器 1 0通过连接导线 9至螺钉 6、 7 , 再通过螺钉 6、 7分别传递 给第一电极板 6和第二电极板 7 , 由此在洗涤水中形成放电， 产生等离子。
所述安装支架 15中部设有电磁波发射头 8 ,所述的电磁波发射头 8由电磁 波驱动器驱动， 并发射电磁波。 就具体方案来说， 安装支架 15 中部设计成像子弹头状的空腔， 电磁波发 射头 8设置在该空腔内。 当第一电极板 6和第二电极板 7工作时， 所述的电磁 波发射头 8由电磁波驱动器驱动， 发射电磁波。 电磁波与等离子的耦合会加速 等离子体的产生速度， 引导和促进等离子在水中交流， 提高杀菌效果。
所述电磁波发射头 8可以为电磁线圈， 所述电磁波驱动器可以为脉冲直流 电源或交流电源， 电磁线圈连接电源， 当线圈中有电流流过时， 产生电磁波并 向水中发射。
控制器 13连接等离子驱动器 10, 控制等离子驱动器 10的工作状态。
实施例 2
参见图 5、 图 6和图 7 , 与上一实施例不同是， 第一电极板 6和第二第电极 板 7竖向间隔设置， 并通过螺钉 6-1、 7-1将所述第一电极板 6与第二电极板 7 固定。 第一电极板 6与第二电极板 7之间的距离可以根据需要选择。
实施例 3
参见图 8-1和图 8-2 , 与上两实施例不同的是， 所述等离子发生器包括第 一电极板 6、 第二电极板 7和第三电极板 18 , 所述第一电极板 6、 第二电极板 7 和第三电极板 18水平上下间隔设置。
所述第一电极板 6与第二电极板 7 , 以及第一电极板 6与第三电极板 18分 别连接电源发生器， 所述电源发生器为直流电源发生器或脉冲电源发生器。
例如， 所述第一电极板 6与第二电极板 7与直流电源发生器连接， 所述第 一电极板 6与第三电极板 18与脉冲电源发生器连接。
或者， 所述第一电极板 6与第二电极板 7与脉冲电源发生器连接， 所述第 一电极板 6与第三电极板 18与直流电源发生器连接。
当然， 还可以有其它选择方式。
釆用脉冲电源发生器可以将脉冲电压提高， 作用到电极板可以在电极板之 间产生电弧放电， 这样产生的正负离子的数量会大大的提高， 且节省用电。 而 釆用下面电极板接直流电源， 上面电极板接高压脉冲电源， 两者之间会有相互 协同的作用， 增加正负离子产生数量。
所述安装支架 15上设置有三个螺钉柱 6-2、 7-2、 18-2和螺钉柱上的螺钉 6-1、 7-2、 18-2 , 所述第一电极板 6、 第二电极板 7和第三电极板 18上下水平 间隔设置， 并通过螺钉将所述第一电极板 6、 第二电极板 7和第三电极板 18固 定所述安装支架 15上， 所述第一电极板 6、 第二电极板 7和第三电极板 18之 间用所述螺钉柱的 6-2、 7-2、 18-2高低不同间隔， 螺钉柱 1 8-2最高并设在中 间， 螺钉柱 6-2次高， 螺钉柱 7-2最低。 这样可以省去实施例 1中的绝缘隔离 套 17。
以上所述， 仅是本发明的较佳实施例而已， 并非是对本发明作其它形式的 限制， 任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改 型为等同变化的等效实施例。 但是凡是未脱离本发明技术方案内容， 依据本发 明的技术实质对以上实施例所作的任何简单修改、 等同变化与改型， 仍属于本 发明技术方案的保护范围。
