参阅图1，本申请一实施例中，提供一种等离子体活化水制备装置100，包括水箱10和电极组件30，水箱10具有容置腔11，电极组件30装配于水箱10上，且伸入容置腔11内，用于放电产生等离子体，使等离子体与水箱10内的水混合反应，生成具有抗癌、杀菌等功能的过氧亚硝酸、过氧化氢、硝酸、亚硝酸等物质，制备得到等离子体活化水。
一些实施例中，等离子体活化水制备装置100还包括与水箱10连接的气液混合机构50，在气液混合机构50的带动下，水箱10内的气体和液体均在水箱10和气液混合机构50之间往复循环并相互混合，即在每次循环过程中使循环路径上的液体和气体相互混合，如此多次循环混合水箱10内的气体和液体，一方面使气体中的等离子体能够和水充分混合，可使等离子体与水充分反应，提高等离子体活化水的制备效率。另一方面，使水箱10内的气体在水箱10与气液混合机构50之间往复循环，防止放电过程中产生的臭氧直接排向外界造成污染，如此还可以减少臭氧排放。
一些实施例中，气液混合机构50包括送气组件52，电极组件30包括第一电极组件32，第一电极组件32包括第一基体321和第一电极325，第一基体321内具有第一放电腔322，第一电极325至少部分伸入第一放电腔322内。在制备等离子体活化水时，第一基体321至少部分伸入容置腔11内承载的液体中，即至少部分伸入容置腔11内的水中，送气组件52用于向第一放电腔322送气，以排出第一放电腔322内的液体，防止第一放电腔322内进水。
并且，送气组件52向第一放电腔322内送气后促使第一基体321底部形成一低位液面，该低位液面相对水箱10内液体的主液面较低且位于第一基体321底部。另外，第一电极325受控在自身端部与低位液面之间产生电弧，以利用第一放电腔322内的第一电极325高压放电，产生位于第一电极325端部与低位液面之间的电弧，即第一电极组件32采用电弧放电模式，可产生浓度较高的过氧化氢，进而有效提高等离子体活化水的杀菌效率。
进一步地，第一基体321上开设有均与第一放电腔322连通的第一进气孔和第一出气孔，送气组件52用于向第一进气孔送气，第一电极325通过第一出气孔与低位液面之间产生电弧。当送气组件52工作时，可输送气流流向第一进气孔，之后气流流经第一放电腔322后从第一出气孔流出，在流出的过程中吹开第一基体321底部的液体形成低位液面。另外，第一电极325通过第一出气孔与低位液面连通，可在通高压后在自身端部与低位液面之间产生电弧，来形成高浓度的过氧化氢，提高杀菌效率。
一些实施例中，电极组件30包括第二电极组件34，第二电极组件34包括第二机体和第二电极345，第二基体341内具有第二放电腔342，第二电极345至少部分伸入第二放电腔342内，且受控在第二放电腔342内进行辉光放电，如此在第二放电腔342内产生等离子体，之后等离子体可与水箱10内的水混合而生成大量的活性粒子，制备得到等离子体活化水。如此，不仅通过第一电极组件32来进行电弧放电，还通过第二电极组件34来进行辉光放电，提高水箱10内活性粒子及过氧化氢的含量并降低PH值，提高等离子体活化水的杀菌率。
可以理解地，辉光放电是指气体中显示辉光的气体放电现象，即第二电极345通电后电离第二放电腔342内的气体，使第二放电腔342内的气体放电并显示辉光。
进一步地，第二电极组件34还包括曝气石346，第二基体341上开设有均与第二放电腔342连通的第二进气孔和第二出气孔，送气组件52还用于向第二进气孔送气，曝气石346安装于第二出气孔处。在实际使用过程中，向水箱10内注入水，第二基体341至少部分伸入水中，通过向第二放电腔342内送气来防止第二基体341进水。并且，通过曝气石346出气，在第二放电腔342内形成的等离子体经过曝气石346后形成气泡再溶入水箱10 内的水中，如此增大等离子体与水的接触面积，提高等离子体与水的反应效率，提高活化水制备效率。
具体到本实施例中，等离子体活化水制备装置100还包括高压交流电源和地电极，高压交流电源的负极与地电极连接，高压交流电源的正极与第一电极325及第二电极345连接，通过高压交流电源为第一电极325及第二电极345同时提供高压交流电，使第一电极325和第二电极345放电。
一些实施例中，送气组件52连接于水箱10顶部与电极组件30之间，用于从容置腔11内吸气并向电机组件送气。当送气组件52向电极组件30内部送气，防止电极组件30内部进水时，送气电极组件30的空气后续被电离后由流出电极组件30，最后从水箱10底部的水中流出汇聚到水箱10顶部。将送气组件52连接在水箱10顶部与电极组件30之间，可将空气通过电极组件30送入水箱10内的水中后，将汇集在水箱10顶部的空气再次送入水箱10内的水中，如此带动空气不断在水箱10顶部-送气组件52-水箱10底部-水箱10顶部之间往复循环，使空气能够与水箱10底部的液体充分混合，进一步提高空气中等离子体与水反应的充分性。并且，经过一次电离的空气进入水箱10底部的水中后流向水箱10顶部，之后可被送气组件52再次带入电极组件30内被电离，使后续电离时空气中本身就留存一部分等离子体，提高电离效率，进而提高等离子体活化水制备效率。
具体地，送气组件52包括送气管521和送气泵523，送气管521的一端与水箱10顶部连接，送气管521的另一端与第一基体321的第一进气口323及第二机体的第二进气口343均连通，送气泵523设于送气管521上，用于带动多功能水箱10顶部的气体流向第一基体321内的第一放电腔322、及第二基体341的第二放电腔342内。
一些实施例中，气液混合机构50包括液体循环组件54及混合件56，混合件56设于容置腔11内，且与容置腔11的底壁及顶壁均间隔设置，以在混合件56与底壁之间预留容置水的空间，在混合件56与顶壁之间预留容置空气的空间。其中，混合件56允许气体及液体通过，液体循环组件54连接水箱10的底部与顶部之间，用于将容置腔11底部的液体输送到容置腔11顶部并流向混合件56。如此，容置腔11底部的液体流向液体循环组件54，然后再流向容置腔11顶部，最后流经混合件56，在混合件56内液体与气体充分混合后一起流向容置腔11底部，在混合件56内完成气体和液体的混合，使包含有等离子体的气体可以与液体充分混合反应，提高等离子体活化水的制备效率。
进一步地，混合件56包括多面空心球，可允许气体及液体通过并在内部相互混合，或者混合件56包括水帘纸，亦可允许气体及液体通过并在内部相互混合。
具体地，液体循环组件54还包括液体循环管541、第一循环泵543及第一喷头545， 液体循环管541连通于容置腔11的底部与顶部之间，第一循环泵543设于液体循环管541上，第一喷头545与液体循环管541连接，且位于容置腔11顶部，电极组件30位于第一喷头545的喷射范围内。这样，水箱10底部的液体在循环泵的带动下从液体循环管541流向水箱10顶部，且从第一喷头545喷出，实现液体循环，使液体流向混合件56中与气体充分混合，来提高等离子体活化水制备效率。并且，从第一喷头545喷射液体时，电极组件30位于第一喷头545的喷淋范围内，可被液体冲淋，进而可使电极组件30降温，防止电极组件30向水箱10中的液体传递热量而使生成的等离子活化水因为温度过高而分解，保证等离子体活化水稳定地容置于水箱10内。
可选地，第一喷头545位于第一电极组件32和第二电极组件34之间，可向第一电极组件32及第二电极组件34均喷淋液体，来对两者进行降温。
参阅图2，另一些实施例中，气液混合机构50包括气液混合组件58，气液混合组件58包括第一输入管581、第二输入管583、输出管585及混合动力件587，第一输入管581和第二输入管583两者的一端分别与容置腔11的顶部和底部连通，第一输入管581和第二输入管583两者的另一端均与混合动力件587的输入侧连通，输出管585连接于混合动力件587的输出侧和容置腔11的顶部之间。水箱10底部的液体及水箱10顶部的空气分别通过第一输入管581和第二输入管583被吸入混合动力件587内，并在混合动力件587内混合后通过输出管585流向容置腔11顶部，返回水箱10，以在循环过程中充分混合气体和液体，提高等离子体活化水制备效率。
进一步地，混合动力件587为气液混合泵，能够将液体及气体吸入自身内部混合后输出。
具体地，气液混合组件58还包括第二喷头589，第二喷头589与输出管585连接并位于容置腔11顶部，电极组件30位于第二喷头589的喷淋范围内，这样通过第二喷头589输出混合有气体的液体，并且向电极组件30喷淋液体，来对电极组件30降温，防止电极组件30向液体传递热量而使生成的等离子活化水因为温度过高而分解，保证等离子体活化水的稳定地容置于水箱10内。
可选地，第二喷头589位于第一电极组件32和第二电极组件34之间，可向第一电极组件32及第二电极组件34均喷淋液体，来对两者进行降温。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能 因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
