如图2所示，所述阳极端子1和阴极端子2通过镀膜电极粘接物7与导电膜4连接，同实施例1中一样，电流直接从阳极端子(或阴极端子)流经导电膜4，实现电解，本实施例中，由于直接连接镀膜电极的导电层，不存在基底材料的串联电阻的影响，因此使得电解池的输入电压可以降低，电解反应的能耗降低，水温也得到降低，电极的使用寿命也延长了许多。As shown in FIG. 2, the anode terminal 1 and the cathode terminal 2 are connected to the conductive film 4 through a plating electrode bond 7, and the current flows directly from the anode terminal (or cathode terminal) through the conductive film 4 as in Embodiment 1. In the present embodiment, since the conductive layer of the plating electrode is directly connected, there is no influence of the series resistance of the base material, so that the input voltage of the electrolytic cell can be lowered, the energy consumption of the electrolytic reaction is lowered, and the water temperature is also lowered. The life of the electrode is also extended a lot.
本实施例中，所述镀膜电极粘接物7为导电银胶或导电锡浆，在保证了阳极端子(或)阴极端子与导电镀膜的连接，同时保证了二者之间的良好的导电性能，当然，本实施例中除了上述粘接物，其它符合本申请技术方案的粘接物也在本申请的保护范围之内。 In this embodiment, the coating electrode bond 7 is a conductive silver paste or a conductive tin paste, which ensures the connection between the anode terminal (or) cathode terminal and the conductive coating, and ensures good electrical conductivity between the two. Of course, in the present embodiment, in addition to the above-mentioned adhesive, other adhesives conforming to the technical solutions of the present application are also within the scope of the present application.
实施例3Example 3
如图3所示，本实施例的结构同实施例1或实施例2，主要区别为：所述阳极端子1和阴极端子2与导电膜4连接处通过密封材料9封装，从而克服了由于连接接触不良，在缝隙间形成局部新阳极和阴极而发生氧化反应，接触部位形成新的氧化层导致电流难以通过，最后连接部位将被腐蚀，所述阴极导电膜和阳极导电膜之间设有质子交换膜6；当然，本实施例中的电解臭氧水装置还可以不设置质子交换膜，如图4所示，其同样可以适用于本发明的技术方案。As shown in FIG. 3, the structure of this embodiment is the same as that of Embodiment 1 or Embodiment 2. The main difference is that the connection between the anode terminal 1 and the cathode terminal 2 and the conductive film 4 is encapsulated by the sealing material 9, thereby overcoming the connection. Poor contact, a local new anode and cathode are formed between the gaps to form an oxidation reaction, and a new oxide layer is formed at the contact portion, so that the current is difficult to pass, and finally the connection portion is corroded, and protons are disposed between the cathode conductive film and the anode conductive film. The membrane 6 is exchanged; of course, the electrolyzed ozone device of the present embodiment may not be provided with a proton exchange membrane, as shown in FIG. 4, which is equally applicable to the technical solution of the present invention.
同时本实施例中，所述阴极基底和阳极基底的末端与电解槽的底部相接触，将阳极室和阴极室完全分隔开，从而保证了产生的臭气和氢气分离，可以得到高纯度的臭氧。In the embodiment, the ends of the cathode substrate and the anode substrate are in contact with the bottom of the electrolytic cell, and the anode chamber and the cathode chamber are completely separated, thereby ensuring separation of the generated odor and hydrogen, and high purity can be obtained. ozone.
