图1是根据本发明一个实施例的气压调节装置的第一状态示意图；图2是根据本发明一个实施例的气压调节装置的第二状态示意图。参见图1、2所示，气压调节装置100包括气管110和密封塞120，其中，气管110具有第一端部111和第二端部112以及连通于第一端部111和第二端部112之间的连通管部113，第一端部111用于连通负压发生腔，第二端部112用于连通大气，第二端部112的通气口1121直径小于连通管部113的管径，密封塞120可往复移动地设置于连通管部113内，以封闭或打开通气口1121，从而通断气管110，从而以平衡负压发生腔的内外压差。
在本发明一些实施例中，密封塞120与连通管部113之间具有间隙，以供气流通过。其中，密封塞120可为柱状，密封塞120的侧壁与连通管部113的内壁间隔设置，从而在通气口1121打开时使气流可经二者间的间隙通过。
在本发明一些实施例中，密封塞120在面朝通气口1121的一侧形成有凸出的弧状端面121，弧状端面121所在球体的直径大于通气口1121的直径，使得密封塞朝第二端部112移动时利用弧状端面121封闭通气口1121，从而可使负压发生腔仅在发生负压时与外部连通。

基于同一发明构思，本发明还提出了一种氧气处理装置200，图3是根据本发明一个实施例的氧气处理装置200的结构示意图；图4是根据本发明一个优选实施例的氧气处理装置200的结构示意图。参见图3、4所示，氧气处理装置200包括壳体210和上述任一实施例中的气压调节装置100，其中，壳体210限定出用于发生电化学反应以处理氧气的负压发生腔211，气压调节装置100的第一端部111与负压发生腔211连通，从而可避免负压发生腔211发生倒吸。
其中，负压发生腔211内可以设置有电化学反应元件(阳极板、阴极板等)，还存放有电解液，例如氢氧化钠溶液等。阳极板、阴极板分别浸于电解液中。
在通电情况下，阴极板用于通过电化学反应消耗流经阴极板的氧气。例如，空气中的氧气可以在阴极板处发生还原反应，即：O2+2H2O+4e-→4OH-。
阳极板与阴极板相互间隔地设置于负极发生腔211内。且在通电情况下，阳极板用于通过电化学反应向阴极板提供反应物(例如，电子)且生成氧气。阴极板产生的OH-可以在阳极板处可以发生氧化反应，并生成氧气，即：4OH-→O2+2H2O+4e-。
壳体210上可设置与负压发生腔211连通的排气口213，氧气处理装置200还可包括排气管220，排气管220的进气经排气口213与负压发生腔211连通，排气管220的出气端伸入位于壳体210外部的水箱300内的水中，使负压发生腔211生成的气体经排气管220排入水中进行过滤后再进入相应使用场景中。
参见图3所示，壳体210上可设置有与负压发生腔211连通的通孔212， 气管110的第一端部111经由通孔212与负压发生腔211连通，通孔212可设置在壳体210顶壁。
参见图4所示，气管110的第一端部111可经由排气口213与负压发生腔211连通。
具体地，排气管220的进气端与气管110的第一端可通过三通管230经由排气口213与负压发生腔211连通。
基于同一发明构思，本发明还提出了一种冰箱400，图5是根据本发明一个实施例的冰箱400的示意性结构框图。参见图5所示，冰箱400包括上述任一实施例中的氧气处理装置200。
氧气处理装置的200的阴极板可与冰箱400的储物间室连通，以消耗冰箱储物间室的氧气，提升冰箱的保鲜效果。
本发明提供的气压调节装置100、氧气处理装置200及冰箱400中，气压调节装置100包括气管110和密封塞120，其中，气管110具有第一端部和第二端部以及连通于第一端部111和第二端部112之间的连通管部113，第一端部111用于连通负压发生腔，第二端部112用于连通大气，第二端部112的通气口1121直径小于连通管部113的管径，密封塞120可往复移动地设置于连通管部113内，以封闭或打开通气口1121，从而通断气管110，从而以平衡负压发生腔的内外压差。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
