具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其他实施例，都属于本申请保护的范围。
此处所称的“一个实施例”或“实施例”是指可包含于本申请至少一个实现方式中的特定特征、结构或特性。在本申请的描述中，需要理解的是，术语“上”、“下”、“顶”、“底”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第 二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含的包括一个或者更多个该特征。而且，术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。
参阅图1，图1为本申请一种可选的冷气阀机构的结构示意图。该冷气阀机构包括第一板结构1和第二板结构2，该第一板结构1上设有第一通风孔11；该第二板结构2包括遮挡结构21，该遮挡结构21与该第一通风孔11匹配，该遮挡结构21与该第一板结构1转动连接，该第二板结构2用于通过该遮挡结构21相对于该第一板结构1的转动，实现对该第一通风孔11连通的通风通道的开启和关闭，该冷气阀机构能够实现在不需要通风的时候，对其的通风通道进行关闭的同时，还能能够遮挡通风孔，美化产品，且防止异物直接掉入通风通道，影响通风效果。
现有技术中的冷气阀通常仅具有关闭功能，其的通风通道处于长期暴露的状态，容易造成异物进入，进而影响通风效果以及制冷设备的寿命，而本申请提供的这种冷气阀机构由于具有两个相对转动的第一板结构1和第二板结构2、且第一板结构1上设有第一通风孔11，进而可以通过二者的相对转动，在不需要体通风的时候，遮挡第一通风孔11，有效避免了异物的进入。
在一种可选的实施方式中，如图2-4所示，图2为本申请一种可选的第二板结构的结构示意图。该第二板结构2上设有第二通风孔22；图3为本申请冷气阀机构处于开启状态的结构示意图；图4为本申请冷气阀机构处于关闭状态的结构示意图。当该第二板结构2转动到第一预设位置时，该第二通风孔22与该第一通风孔11连通，使该通风通道开启；当该第二板结构2转动到第二预设位置时，该遮挡结构21能够遮挡该第一通风孔11，使该通风通道关闭。从而可以使得在实现对通风通道的开启和关闭的同时，还能增加第二板结构2的结构灵活性，还可以通过对第二通风孔22的设计，引导冷气经通风通道进入第一通风孔11，例如，第二通风孔22的靠近第一 通风孔11的孔的直径小于远离第一通风孔11的孔的直径。
在一种可选的实施方式中，如图3所示，该第一通风孔11以格栅结构设置于该第一板结构1上，该格栅结构能够进一步降低较小的异物通过第一通风孔11进入通风通道的情况，从而有效保障通风效果。
在一种可选的实施方式中，该第二板结构2包括相对的第一侧和第二侧；该第一侧靠近该第一板结构1；该第二侧靠近制冷装置，即该第二板结构2位于第一板结构1与制冷装置之间的区域，具有美观的效果。
在另一种可选的实施方式中，该第二板结构2包括相对的第三侧和第四侧；该第三侧靠近该第一板结构1；该第四侧靠近制冷装置。
在一种可选的实施方式中，从图3可以看出，该第一板结构1还包括标识提示区域12；该标识提示区域12上设有转动标识121，该转动标识121用于指示当该第一通风孔11开启时，该第二板结构2转动的方向，可选的，可以是如图3所示的标识，该转动标识121可以包括转动方向的箭头或者指示线、图案、文字以及字母等。
在一种可选的实施方式中，该第二板结构2的中部设有凸起23；该第一板结构1上设有与该凸起23相匹配的凹槽，从而使得二者配合，便于后续将第一板结构1和第二板结构2的中部转动连接。
在一种可选的实施方式中，如图5所示，图5为本申请另一种可选的冷气阀机构的结构示意图。该第二板结构2上设有卡扣24，该卡扣24用于将该第二板结构2与该第一板结构1卡接。
在一种可选的实施方式中，该第一板结构1的横截面积的形状包括圆形、方形和菱形；该第二板结构2的横截面积的形状包括圆形、方形和菱形。
在一种可选的实施方式中，该第一板结构1包括凹槽结构，该第一板结构1的侧面设有防滑纹；该第二板结构2包括平板。
需要说明的是，根据需要第一板结构1的横截面积、结构以及第二板结构2的横截面积、结构还可以是其他的，在此不做限定，优选的，该第一板结构1和第二板结构2的横截面积的形状均为圆形，第一板结构1为凹槽结构，且槽体为圆台柱，第二板结构2为平板，便于二者安装。
本申请在另一方面还公开了一种冷却装置，其包括上述的冷气阀机构。
本申请在另一方面还公开了一种车辆，其包括上述的冷却装置。
以上所述仅为本申请可选实施例，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
