具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本发明进行详细描述。
下面参照图1至图8来描述本发明实施例的极板组件40、氧气处理装置以及冰箱30。本发明实施例提供了一种用于氧气处理装置的极板组件40。图1是根据本发明一个实施例的用于氧气处理装置的极板组件40的示意性结构图。图2是图1所示的用于氧气处理装置的极板组件40的另一视角的示意性结构图。图3是图1所示的用于氧气处理装置的极板组件40的示意性分解图。极板组件40整体上可作为氧气处理装置的电极，并装配至氧气处理装置的指定位置，以在电化学反应过程中发挥氧气处理功能。极板组件40一般性地可包括电极板700和压力保护机构900。
其中，电极板700用于在电解电压的作用下通过进行电化学反应处理氧气，例如消耗氧气和/或产生氧气，从而起到调节空间内的氧气含量的作用。电极板700可以呈板状，例如板状电极。电极板700的板面可以为平整的板面。
电极板700的电化学反应类型本实施例不做具体限定，只要能够以氧气作为反应物或者生成物均可，例如，氧还原反应，或者含氧离子的氧化反应，等等。
压力保护机构900包绕电极板700的板面两侧，以夹持电极板700，从而防止电极板700产生形变。“夹持”是指，压力保护机构900与电极板700的板面之间产生相互作用力，使电极板700的板面保持平整。压力保护机构900同时与电极板700的板面两侧接触，从而起到夹持作用。
压力保护机构900的具体形状本实施例不做具体限定，只要其包绕住电极板700的板面两侧即可。例如，压力保护机构900可以包括设置在电极板700的板面一侧的第一面板以及设置在电极板700的板面另一侧的第二面板；或者压力保护机构900可以为包绕住电极板700的板面以及边沿的护框结构。
采用上述方案，通过利用压力保护机构900包绕电极板700的板面两侧，以夹持电极板700，形成极板组件40，压力保护机构900可以为电极板700的板面提供支撑，使电极板700的板面能够在压力保护机构900的支撑作用下增强抗压能力。基于此，本实施例的方案，利用压力保护机构900保护电极板700，可减少或避免电极板700受压发生形变，提高电极板700的结构稳定性和性能稳定性。
在一些可选的实施例中，压力保护机构900具有限定出多个孔910的多孔区域，以允许电极板700通过多孔区域与周围环境接触。且多孔区域均匀分布于电极板700的板面两侧。多孔区域的孔910可以作为电极板700的板面与周围环境接触的窗口。例如，电极板700所在环境中的气体或液体可以通过孔910与电极板700的板面接触。
通过在压力保护机构900上设置多孔区域以允许电极板700与周围环境接触，可使电极板700通过多孔区域接触周围环境中的气体和液体，有利于减少或避免压力保护机构900对电极板的电化学反应产生不利影响，使电极板700在压力保护机构900的保护作用下正常发挥氧气处理功能。
由于压力保护机构900的多孔区域均匀分布于电极板700的板面两侧，具有多孔区域的 压力保护机构900能够与电极板700的多个位点产生作用力，因此，该压力保护机构900具有较高的结构强度，能够在不影响电极板700与周围环境接触的基础上发挥良好的支撑作用，防止电极板700受压产生形变。
在一些可选的实施例中，压力保护机构900包括环绕电极板700的边沿的边框部920以及平铺于电极板700的板面两侧的面框部940。电极板700的边沿嵌入并被夹持于边框部920。也就是说，压力保护机构900既夹持在电极板700的板面两侧，又夹持着电极板700的边沿，形成全面型的保护结构。多孔区域位于面框部940上，以便电极板700的板面与周围环境接触。
本实施例中，面框部940为两个，且分布于电极板700的板面两侧，以夹持电极板700。边框部920可以呈环状。面框部940可以平铺于环状边框部920的内圈区域。两个面框部940之间形成间隔，以容纳电极板700。
采用上述方案，压力保护机构900既可以作为全面型的保护结构将电极板700全面地包绕起来，辅助电极板700提升抵抗外界压力冲击的能力，又可以作为将电极板700固定装配至氧气处理装置的连接结构，可巧妙地降低电极板700相对于氧气处理装置的装配难度。电极板700仅需要先装配至压力保护机构900，然后再将压力保护机构900固定至氧气处理装置即可。在氧气处理装置的装配过程中，电极板700无需直接装配至氧气处理装置。
在一些进一步的示例中，面框部940与边框部920以及电极板700一体注塑成型，从而相互连接或者相互嵌入或者实现夹持。也就是说，整个压力保护机构900可以利用注塑成型工艺制造出来。
边框部920上形成有供电极板700的边沿嵌入其中以实现装配的环状的凹槽922。当面框部940与边框部920一体成型时，电极板700可以在面框部940与边框部920的成型过程中嵌入其中，使电极板700的边沿嵌入面框部940中，并使电极板700的板面嵌入两个面框部940之间，以被夹持。
通过一体成型工艺制造压力保护机构900，有利于简化压力保护机构900的制造工序，省略边框部920与面框部940之间的连接工序，且提高压力保护机构900的机械强度。
当然，在另一些实施例中，边框部920和面框部940也可以不为一体件，且可以连接固定成一体。连接固定的方式包括但不限于以下任一方式或其组合：螺接、粘接、焊接和铆接。
在一些可选的实施例中，平铺于电极板700板面每一侧的面框部940包括多个错位排布的支撑筋，每一支撑筋分别跨设于边框部920的内周面的不同部位之间。且相邻支撑筋之间的空隙形成多孔区域。
如图1-4所示，例如，边框部920可以呈方环状，且包括依次首尾相接的四个边框。每一支撑筋可以自边框部920的一个边框的内周面延伸至另一边框的内周面。边框部920的内周面是指边框部920朝向其环内区域的一面。
图4是图1所示的用于氧气处理装置的极板组件40的压力保护机构900的示意性结构 图。图5是图4所示的用于氧气处理装置的极板组件40的压力保护机构900的示意性剖视图。在一个示例中，多个支撑筋包括沿第一方向依次间隔排布的多个第一支撑筋942a以及沿第二方向依次间隔排布的多个第二支撑筋942b。由于第一方向不同于第二方向，因此，第一支撑筋942a与第二支撑筋942b之间形成夹角。
例如，边框部920的四个边框可包括两个长度方向的边框和两个宽度方向的边框，第一支撑筋942a可以自一个长度方向的边框延伸至一个宽度方向的边框，第二支撑筋942b可以自另一个长度方向的边框延伸至另一个宽度方向的边框，从而与第一支撑筋942a形成夹角。
在一些可选的实施例中，电极板700包括自其主体板面向上凸出延伸的接电端720。该接电端720用于与外部的电源相连接，从而将电极板700与外部的电源建立电连接。
边框部920的上方相应设置有接电壳960，接电壳960的内部形成贯通凹槽922以供接电端720插入其中的接电腔。接电壳960上开设有连通接电腔的接电通孔964，以供接电端720或连接接电端720的电插接件经其穿出接电壳960。其中，电插接件例如可以为导线或者具有导电功能的其他部件。穿出接电壳960的接电端720或者接电端720的电插接件可以通过导线连接至外部的电源。
换言之，本实施例的压力保护机构900既具备保护电极板700的功能，又为电极板700与外部的电源建立电连接提供接电场所，解决了电极板700因被包绕而导致接电困难的问题。
并且，由于接电壳960位于边框部920的上方，当将边框部920固定装配至氧气处理装置的安装口530，并使边框部920与电极板700共同封闭安装口530时，接电壳960可以裸露于电解腔的外部，处于接电壳960内的接电端720不会因发生爬碱问题而导致电连接故障。
因此，采用上述结构，压力保护机构900能够提高电极板700与外部电源之间的电连接结构的稳定性。
压力保护机构900由阻燃材料制成。例如，压力保护机构900可以由符合灼热丝750针焰测试要求的阻燃材料制成，或者由阻燃等级达到HB等级的阻燃材料制成。
采用上述结构，通过在电极板700的周边包绕具有阻燃功能的压力保护机构900，当该压力保护机构900吸收电极板700进行电化学反应时所产生的热量时，能够在较大程度上抵抗物性变化，从而减少或避免氧气处理装置的电极板700因进行电化学反应发热而导致周围部件损毁，提高装置的使用安全性和结构稳定性。
使用上述阻燃材料制成压力保护机构900，即使电极板700的工作电流超过预设阈值，也不会导致氧气处理装置及其周围部件因温度过高而发生损毁。预设阈值可以为0.1～0.2A范围内的任意值。
本发明实施例还提供了一种氧气处理装置，其包括壳体500以及如以上任一实施例的用于氧气处理装置的极板组件40，还可以进一步地包括对电极板。图6是根据本发明一个实施例的氧气处理装置的壳体500的示意性主视图。图7是根据本发明一个实施例的氧气处理装置的壳体500的示意性结构图。
电极板700的极性可以为阳极或阴极。在一些可选的实施例中，电极板700为阴极。对电极板的极性与电极板700的极性相反，且设置于壳体500内，用于在电解电压的作用下进行电化学反应，从而与电极板700配合以处理氧气。电极板700可以用于在电解电压的作用下通过电化学反应消耗氧气。对电极板则用于在电解电压的作用下通过电化学反应向电极板700提供反应物(例如，电子)且生成氧气。
壳体500内限定出用于盛装电解液的电解腔。电解腔内可以盛装碱性电解液，例如1mol/L的NaOH，其浓度可以根据实际需要进行调整。空气中的氧气可以在电极板700处发生还原反应，即：O2+2H2O+4e-→4OH-。对电极板设置于电解腔内，并配置成通过电化学反应向电极板700提供反应物，且生成氧气。例如，对电极板产生的OH-可以在电极板700处发生氧化反应，并生成氧气，即：4OH-→O2+2H2O+4e-。
以上关于电极板700和对电极板的电化学反应的举例仅仅是示意性的，在了解上述实施例的基础上，本领域技术人员应当易于变换电化学反应的类型，或者针对适用于其他电化学反应类型的氧气处理装置的结构进行拓展，这些变换和拓展均应落入本发明的保护范围。
当利用氧气处理装置消耗储物空间810内的氧气时，可使电极板700与储物空间810气流连通，以便电极板700利用储物空间810内的氧气为反应物进行电化学反应；当利用氧气处理装置向储物空间810提供氧气时，可使对电极板或者电解腔与储物空间810气流连通，以便对电极板将其进行电化学反应的生成物向储物空间810提供。
壳体500的侧壁上开设有安装口530。装配有电极板700的压力保护机构900固定装配至安装口530的周缘，以与电极板700共同封闭安装口530，且与壳体500限定出用于盛装电解液的电解腔。
极板组件40可以覆盖在安装口530的内侧或外侧，从而起到封闭安装口530的作用。其中，安装口530的“内侧”和“外侧”是相对于壳体500而言的，例如安装口530的内侧是指安装口530朝向壳体500内部空间的一侧，安装口530的外侧是指安装口530朝向壳体500外部空间的一侧。
在一些进一步的实施例中，安装口530的外周环绕有朝向壳体500外部凸出且呈环状的环状凸起540。且压力保护机构900的边框部920与环状凸起540之间通过热板焊接固定。压力保护机构900的边框部920上相应形成有与环状凸起540相对且呈环状的环状凸圈926。环状凸起540和环状凸圈926可以通过热熔固定到一起。
当压力保护机构900的边框部920为包绕电极板700的环状边框，且压力保护机构900的边框部920与壳体500的安装口530周缘通过热板焊接装配成一体时，由于焊接强度高，牢度可靠，因此，与采用卡接或者螺接等方式进行装配的方案相比，本实施例的方案能够增强氧气处理装置的密封性能，减少或避免电解液泄露问题。
壳体500可以通过注塑一体成型。在一些可选的实施例中，压力保护机构900与壳体500的材质相同。当相同材质的物件通过热板焊接装配成一体时，可保证较高的焊接强度， 且降低焊接的工艺难度。
当压力保护机构900与壳体500的材质相同时，壳体500也由阻燃材料制成，这使得壳体500本身也能获得与阻燃框大致相当的抵抗物性随热量变化的能力，从而提升整个氧气处理装置的使用安全性和结构稳定性，确保整个氧气处理装置的周围部件或使用环境处于较高安全系数的状态。
在一些可选的实施例中，阻燃材料包括ABS和阻燃剂，例如可以为阻燃ABS材料。压力保护机构900和环状凸起540(或者整个壳体500)可以分别由阻燃ABS材料制成。
在ABS中添加阻燃剂，可成为具备良好阻燃效果的阻燃材料，由该阻燃材料制成的壳体500以及装配于壳体500上的压力保护机构900在电极板700进行电化学反应时不会发生明显的形变，具备优良的结构保持性能。
壳体500上可以开设有排气口，用于排出对电极板的电化学反应所产生的氧气。壳体500上还可以开设有补液口，该补液口可以与储液装置相连通，用于允许储液装置所盛装的液体流入壳体500内。壳体500的电解腔的一侧可以形成有与电解腔连通的储液腔，例如，电解腔与储液腔之间可以形成有连通口。补液口连通储液腔，以向储液腔输送液体，从而起到向电解腔补液的目的。储液腔内可以设置有液位开关，用于根据储液腔内的液位通断补液口与储液腔之间的液路。
安装口530的数量可以为多个，每个开口处分别可以设置有一个电极板，且每个电极板分别与一对电极板相对。
本发明实施例还提供了一种冰箱30。图7是根据本发明一个实施例的冰箱30的示意性结构图。冰箱30一般性地可包括箱壳800和如以上任一项的氧气处理装置。
其中，箱体的内部形成储物空间810。氧气处理装置用于在电解电压的作用下通过进行电化学反应处理储物空间810内的氧气，例如消耗储物空间810内的氧气，和/或向储物空间810提供氧气。
当利用氧气处理装置消耗储物空间810内的氧气时，可使电极板与储物空间810气流连通，以便电极板利用储物空间810内的氧气为反应物进行电化学反应；当利用氧气处理装置向储物空间810提供氧气时，可使对电极板或者电解腔与储物空间810气流连通，以便将对电极板进行电化学反应生成的氧气向储物空间810提供。
本发明的极板组件40、氧气处理装置以及冰箱30，通过利用压力保护机构900包绕电极板700的板面两侧，以夹持电极板700，形成极板组件40，压力保护机构900可以为电极板700的板面提供支撑，使电极板700的板面能够在压力保护机构900的支撑作用下增强抗压能力。基于此，本发明的方案，利用压力保护机构900保护电极板700，可减少或避免电极板700受压发生形变，提高电极板700的结构稳定性和性能稳定性。
以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同 替换，而不脱离本发明技术方案的精神和范围。
