Description

金刚石膜电解臭氧便携式消毒器 技术领域

具体实施方式
现结合附图，对本发明的较佳实施例作详细说明。
如图1至图9所示，一种金刚石膜电解臭氧便携式消毒器，包括盛水腔体1、喷洒装置3和臭氧发生单元2，盛水腔体1呈圆柱体状或长方体状等，内部中空，内部空腔用于盛装纯净水。所述喷洒装置3设在盛水腔体1顶部，喷洒装置3采用按压式喷头，所述臭氧发生单元2设置于盛水腔体1底部。该臭氧发生单元包括两块电极片9，夹在两块电极片9之间的两块用于电解的金刚石膜片4以及夹在两块金刚石膜片4之间的离子膜5。金刚石膜片4可以采用掺硼金刚石膜片，所述离子膜5可以采用阳离子膜。
一些实施例中，所述盛水腔体1包括内壳1-1和外壳1-2，所述内壳1-1下部有螺纹，与外壳1-2的底部旋紧固定，金刚石膜片4和离子膜5固定安装在内壳1-1底面，在水被消耗完时，可将内壳1-1旋出，便于使用人员向盛水腔体1内加入纯净水。臭氧消毒器可进行多次加水和制取臭氧水，保证消毒器的可重复使用性。内壳1-1和外壳1-2之间设有密封圈14，有效避免盛水腔体内的水外漏。
一些实施例中，所述金刚石膜片4上布设有通孔，以有效增大金刚石膜片4与水的接触面积，提高水电解制取臭氧的效率。
一些实施例中，所述臭氧发生单元2设置在安装座6上。如图2、图6、图8和图9所示，安装座6上设有容纳金刚石膜片4和离子膜5的凹槽，两片金刚石膜片4和离子膜5嵌入凹槽内，两块电极片9分别设置在安装座的上下表面，并分别与临近的金刚石膜片4接触。由于金刚石膜片强度很脆，不能强行固定，不能施加过大的力，且金刚石膜片是耗材，使用过程中厚度会有变化。因此，如何将金刚石膜片巧妙地固定相当重要。本实施例中，电极片9包括固定部分和从固定部分延伸的接线片9-2，本实施例中，固定部分为固定框9-1，其它实施例中，固定部分也可以是固定网。该固定框9-1与金刚石膜片4贴合，固定框9-1中间设有通孔，避免阻挡金刚石膜片4与水接触，从而尽量增大金刚石膜片4与水的接触面积。接线片9-2上设有用于螺丝11通过的孔，螺丝10穿越接线片9-2上的孔将电极片9的一端固定，而电极片9的另一端即固定框9-1一端不固定，为自由端。俩电极片9交错设置，各自的固定框9-1上下相对，将金刚石膜片4夹住。而俩电极片9的接线片9-2横向上相对远离，由于俩电极片9均只有外端(接线片9-2端)被固定，内端即固定框这一端为自由端，如此上下俩电极片9之间形成一定的弹性变形空间。当金刚石膜片的厚度有变化时，电极片9会有弹性变化来补偿，不会给金刚石膜片过大的力，也能保证臭氧发生单元位置的稳定。
所述螺丝11穿越接线片9-2的孔和安装座6之后，由螺母12将安装座6与内壳1-1底面固定。本实施例中，螺丝11和螺母12均为导电材料，比如，螺丝采用纯钛，螺母采用黄铜。电源通过螺母和螺丝将两块电极片连接。
如图8和图9所示，安装座6底部设有支撑脚6-1，支撑脚6-1与内壳1-1底面固定连接或一体成型。通过支撑脚6-1，将位于安装座6底部的金刚石膜片4相对内壳1-1底面悬空，即保证工作时下面的金刚石膜片4也能充分与水接触，最大限度增大金刚石膜片4与水的接触面积，同时，使位于底部的金刚石膜片4上产生的臭氧能够向上流通，增强盛水腔体1内水的流通性，有效提高臭氧的制取效率。
一些实施例中，所述的盛水腔体1上设有透明观察窗7，透明观察窗7由透明材料制成，如亚克力板、透明塑料板、玻璃等，使得使用者能够更好地掌握盛水腔体1内水的多少，方便使用者根据需要及时向盛水腔体1内添加水。
一些实施例中，还包括旋接在盛水腔体1下方的底壳8，底壳8内设有蓄 电池15和电路板16，蓄电池15的正负极分别直接或间接与两块电极片连接，通过蓄电池使得使用者在找不到外部电源的时候也能够进行臭氧消毒水的制取，使用更加方便。为提高臭氧制取效率，可在电源与电极片9之间添加升压模块，加快臭氧消毒水的制取速度。
一些实施例中，如图5和图9所示，臭氧发生单元2上方罩盖有不锈钢装饰罩17。
本实施例中，便携式消毒器的电压范围大致在7-15V，加水量在10-15ml，产生的臭氧浓度为0.3-1mg/l，适用于对化妆箱包、衣柜、车厢以及办公桌上进行消毒杀菌。
如图9所示，使用时，两块电极片9分别直接或间接与电源的正负极连接，在盛水腔体1中加入水，臭氧发生单元2浸没于水中，通电后，通过两块金刚石膜片4的作用对盛水腔体1内的水进行电解，电解产生的臭氧混合在水中，形成具有消毒作用的臭氧消毒水。然后通过喷洒装置3将臭氧消毒水压出并喷洒到需要消毒物体表面，能够快速、实时制取臭氧消毒水，使用方便，整体结构设计紧凑，体型小巧，方便随身携带。
本发明产品的金刚石电极可以采用中材人工晶体研究院的制备技术，安全无毒，在电解水时可产生一定浓度的臭氧和羟基自由基，具有广谱高效的消毒杀菌作用，能够降解几乎所有的有机物，包括大多数农残。
广州市微生物研究所有限公司对本发明产品做了消毒测试，结果表明本发明产品对大肠杆菌、金黄色葡萄球菌、沙门氏菌等细菌在短时间内的消杀率达到99.999％，超过国家标准的99.9％。本发明产品测试结果显示金刚石电极产生的臭氧气泡水对甲型流感病毒的消杀率达到99.68％，超过国家标准的99％。
本发明产品所产生消毒液的主要杀菌因子是臭氧，水中含有的臭氧因子随着水分一起挥发，达到零残留的效果。臭氧水能与细菌细胞壁脂类的双键反应，穿入菌体内部，作用于蛋白即脂多糖，改变细胞的通透性，从而导致细胞溶解死亡。
本发明产品所产生的消毒水能消灭新冠病毒，中国科学院武汉病毒研究所的检测结果表明，CT值为4.07mg/L-min的纳米气泡臭氧水在1分钟内完全灭活4log(4×10 4pfu/ml)的新冠病毒SARS-COV-2。
应当理解的是，以上实施例仅用以说明本发明的技术方案，而非对其限制， 对本领域技术人员来说，可以对上述实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改和替换，都应属于本发明所附权利要求的保护范围。
