详细描述
为使本申请的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本申请作进一步详细的说明。
本申请的核心构思之一在于，压缩机包含有第一缸体2和第二缸体5，第二缸体5从第一缸体2顶部延伸至第一缸体2内，在吸入第一缸体2外的气体后，通过复用第一缸体2与第二缸体5之间的空间分别对气体进行一、二级压缩，第二缸体5吸收经过二级压缩后的气体并进行三级压缩，实现在保持第一缸体2占用空间的基础上，对气体依次进行三级压缩，输出高压气体。
参照图1，示出了本申请的一种气体压缩装置实施例的第一视角结构图，参照图2，示出了本申请的一种气体压缩装置实施例的一种第二视角剖视图。本申请实施例具体可以包括：顶盖1、与所述顶盖1连接的第一缸体2、位于所述第一缸体2下方的驱动机构3、位于所述第一缸体2内的活塞组件4，以及从所述顶盖1延伸至所述第一缸体2内的第二缸体5；所述驱动机构3用于驱动活塞组件4进行往返移动；
所述活塞组件4包括位于所述第一缸体2与所述第二缸体5之间的第一活塞401、与所述第一活塞401连接的第一活塞连接杆402，位于所述第二缸体5内的第二活塞403、与所述第二活塞403连接的第二活塞杆404，以及与所述第一活塞连接杆402、第二活塞杆404连接的活塞底座405；所述活塞底座405与所述驱动机构3连接；
在具体实现中，第一活塞401、第一活塞连接杆402和活塞底座405可以为一体成型结构，也可以为可分离结构；第二活塞403、第二活塞杆404和活塞底座405可以为一体成型结构，也可以为可分离结构，即第二活塞杆404可以与活塞底座405刚性连接，也可以是第二活塞杆404可以与活塞底座405接触连接，本申请实施例对此不作限定。
在所述第一活塞401上方，由所述顶盖1、所述第一活塞401、所述第一缸体2和所述第二缸体5形成第一压缩腔6，以及，在所述第一活塞401下方，由所述第一活塞401、所述第一缸体2和所述第二缸体5形成第二压缩腔7；
由所述第二活塞402、所述第一活塞连接杆402和所述顶盖1形成第三压缩腔8。
需要说明的是，该第一缸体2可以采用合金，塑料或有机材料等耐高温、高硬度材料。该第一缸体2可以是方体，圆柱体，也可以是不规则体。该第一缸体2的容积可以根据实际需要进行调整，若需要压缩大容量的气体时，可以适当增加第一缸体2的体积，从而可以增加第一缸体2内气体的容量，若需要压缩小容量的气体时，可以适当减少第一缸体2的体积，可以减少第一缸体2内气体的容量。第二缸体5与第一缸体2类似，可以针对第一缸体2做相似调整，在此不再赘述。
参照图3，示出了本申请的一种气体压缩装置实施例的另一种第二视角剖视图。
驱动机构3驱动活塞底座405往返移动，活塞底座405通过第一活塞连接杆402、第二活塞杆404驱动第一活塞401和第二活塞403往返移动。第一活塞401在第一缸体2与第二缸体5之间的空间进行往返移动，以使第一活塞401在第一位置点(如图2所出示的第一活塞401所处位置)与第二位置点(如图3所示的第一活塞401所处位置)之间进行往返移动，以及，第二活塞403在第三位置点(如图2所出示的第二活塞403所处位置)与第四位置点(如图3所示的第二活塞403所处位置)之间进行往返移动，即驱动组件303驱动第一活塞401与第二活塞403同步移动。
在第一活塞401往返移动的空间中，由所述顶盖1、所述第一活塞401、所述第一缸体2和所述第二缸体5形成在所述第一活塞401上方的第一压缩腔6，以及，由所述第一活塞401、所述第一缸体2和所述第一活塞连接杆402形成在所述第一活塞401下方的第二压缩腔7，可以理解的是，第一压缩腔6和第二压缩腔7的空间随第一活塞401移动而变化。
当第一活塞401从第一位置点移动至第二位置点时，将第一缸体2外部的气体吸入至第一压缩腔6内；第一活塞401从第二位置点往第一位置点时，将从第一缸体2外部吸入的气体进行一级压缩得到一级压缩气体，同时，第二压缩腔7体吸入一级压缩气体，由于第二压缩腔7的体积小于第一压缩腔6的体积，所以当气体进入第二压缩腔7时，第二压缩腔7内的气体压强会大于第一压缩腔6吸入的气体压强。当第一活塞401再次从第一位置点移动至第二位置点时，第一压缩腔6体再次吸入第一缸体2外部的气体，以及第一活塞401将一级压缩气体进行二级压缩得到二级压缩气体，同时，第二活塞 403从第四位置点移动至第三位置点，将二级压缩气体吸入至第三压缩腔8内。当第一活塞401再次从第二位置点移动至第一位置点时，第二活塞403从第三位置点移动至第四位置点，第二活塞403将二级压缩气体进行三级压缩生成三级压缩气体，并输出至第一缸体2外部，从而实现对气体的三级压缩，进一步的，在驱动机构3的驱动下，针对气体的一级压缩和三级压缩能够同步进行，一级压缩与二级压缩异步进行，提高对气体的压缩效率。
在本申请实施例中，气体压缩装置包括有顶盖1、第一缸体2、驱动机构3、活塞组件4、第二缸体5，第一活塞401位于第一缸体2内壁与第二缸体5外壁之间，并在第一活塞401上方，由顶盖1、第一活塞401、第一缸体2和第二缸体5形成第一压缩腔6，以及，在第一活塞401下方，由第一活塞401、第一缸体2和第二缸体5形成第二压缩腔7，以复用第一缸体2与第二缸体5之间的空间，在第一活塞401往返移动中得到第一压缩腔6和第二压缩腔7，以对从第一缸体2外部吸入的气体进行一级压缩和二级压缩，并由所述第二活塞403、所述第二缸体5和所述顶盖1形成第三压缩腔8，通过第二活塞403将经过二级压缩后的气体吸入至第三压缩腔8内进行三级压缩得到三级压缩气体，从经由顶盖1输出三级压缩气体，从而实现复用第一缸体2与第二缸体5之间的空间对气体进行一级压缩和二级压缩，并在位于第一缸体2中的第二缸体5内对气体进行三级压缩，使得气体压缩装置的体积较小，同时，对气体进行多级压缩，提高对气体的压缩效率。

转轴3031的一端与曲轴连接板3023连接，另一端设置有第三轴承3036，进一步减少转轴3031的转动摩擦力，同时，更好的稳定转轴3031的位置。
罩体3034覆盖在齿轮3032外部，以保护齿轮3032，防止齿轮3032由于外部物体导致受损。
在具体实现中，电机3033输出轴还连接有至少一个扇叶3037，在电机3033驱动齿轮3032进行转动时，扇叶3037同步转动，增强电机3033附近的空气流动，对电机3033进行散热。
电机3033可以选择高功率电机3033，可以选择高转速电机3033，也可以选择搞扭矩电机3033，电机3033的类型可以根据实际需要进行调整，本申请实施例对此不作限定。
在本申请的一种可选实施例中，所述气体输出组件10包括依次连接的排气阀1001、第一导管1002、冷凝器1003，与所述冷凝器连接的过滤器1004、输出接头1005，以及，设置在所述冷凝器1004上的一个或多个流体控制阀1006、设置在所述过滤器上的压力表1007、与所述输出接头1005连接的安全 阀1008。
在第二活塞403从第三位置点移动至第四位置点时，由于三级压缩气体的气压较大，使得排气阀1001处于开启状态，三级压缩气体在压强作用下经过第一导管1002传输至冷凝器1003，冷凝器1003中可以装载有液体，由于气体经过压缩后，可能会存在温度升高的情况，冷凝器1003中的液体能够吸收三级压缩气体中的热能，以降低三级压缩气体的温度。
过滤器1003中设置有相应材料对三级压缩气体进行过滤，去除三级压缩气体中的部分或全部杂质。其中，过滤器1003中可以设置有滤棉、分子筛和活性炭中的一种或多种材料。
过滤后的三级压缩气体经过输出接头1005、安全阀1008后向气体压缩装置外部输出，以实现向气体压缩装置外部输出过滤的经过三级压缩的高压气体。
其中，在冷凝器1004上设置有一个或多个流体控制阀1006，用于控制流体(例如：水)流入/流出冷凝器。在本实施例中，流体控制阀可以包括第一排水阀10061和第二排水阀10062。过滤器1004设置有检测气体压强的压力表1007。

所述进气滤芯103与所述进气阀102之间设置有注油孔104。
在第一活塞401从第二位置点(如图6所示)移动至第一位置点(如图7所示)时，由于第一压缩腔6气压小于外部气压，进气阀102被打开，进气孔101与第一压缩腔6连通，则第一缸体2外部的气体经过进气滤芯103、进气孔101、进气阀102后，被吸入至第一腔体内。
在本申请的一种可选实施例中，还包括：
套设在所述第一活塞401的第一活塞环12、套设在所述第二活塞403的第二活塞环13、设置在所述第一缸体2底部并与所述第一活塞连接杆402接触连接的第三活塞环14、设置在所述第一缸体底部的导套15。
第一活塞环12用于防止第一压缩腔6中的气体从第一活塞401与第一缸体2之间的连接处流向至第二压缩腔7；第二活塞环13用于防止第三压缩腔8中的气体从第二活塞403与第二缸体5之间的连接处流向第二活塞403与活塞底座405之间的位置；第三活塞环14用于防止第二压缩腔7中的气体从第一活塞连接杆402与第一缸体2底部之间的连接处流向第一缸体2外部；

在本申请的另一可选实施例中，第二活塞403和第二活塞杆404为一体式柱塞结构，通过第二活塞403与第二缸体5之间紧密贴合实现密封，无需设置软性材料(如上所述的第二活塞环13)进行密封。
参照图5，示出了本申请的另一种气体压缩装置实施例的第一视角剖视图。在本申请的另一可选实施例中，所述顶盖1设置有进气孔101、进气阀102、进气滤芯103、第二导管105、连接件106、滴油部件107以及储油部件108；

所述滴油部件107、所述储油部件108嵌入所述连接件106，所述滴油部件107和所述储油部件108相对设置，所述滴油部件107用于向所述储油部件输出油雾；
当外部气体经过进气滤芯103后，气体从所述滴油部件107和所述储油部件108之间的位置流向第二导管105，使得滴油部件能够自动输出油雾，油雾随气体一同经过第二导管105、进气孔101、进气阀102进入第一压缩腔6内。
其中，滴油部件107能够按照一定频率输出油雾，滴油部件107中设置有可以调节油雾大小的油雾器。
