具体实施方式
为使本实用新型的上述目的、特征和优点能够更加明显易懂，下面结合附图对本实用新型的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本实用新型。但是本实用新型能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本实用新型内涵的情况下做类似改进，因此本实用新型不受下面公开的具体实施例的限制。
参阅图1及图2，一实施例中的压缩机构10，能够实现对介质的压缩，为介质的流动提供动力。在本实施例中，压缩机构10用于实现对气体的压缩，为气体的流动提供动力。在其他实施例中，压缩机构10还可以用于实现对气液混合介质等的压缩。
一实施例中，压缩机构10包括压缩缸100及活塞组件200，压缩缸100内形成有压缩腔110，且压缩缸100上形成有进入通道120及排出通道122(如图6所示)，进入通道120与排出通道122均与压缩腔110连通；活塞组件200包括活塞本体210及活塞杆220，活塞本体210设置于压缩腔110内，活塞本体210朝向排出通道122的一端上设置有弹性垫230，活塞杆220的一端连接于活塞本体210上，活塞杆220能够带动活塞本体210往复移动，使介质由进入通道120进入到压缩腔110内并通过排出通道122压出。
在使用时，将活塞组件200设置于压缩缸100的压缩腔110内，通过活塞组件200的活塞杆220带动活塞本体210在压缩缸100内进行往复移动，当活塞本体210朝远离排出通道122的方向移动时，以使介质由进入通道120进入到活塞本体210朝向排出通道122一侧的压缩腔110内。当活塞本体210朝排 出通道122的方向移动时，能够将介质通过排出通道122压出。由于活塞本体210朝向排出通道122的一端设置有弹性垫230，当活塞本体210移动至排出通道122与压缩腔110连通的内壁相抵接时，能够利用弹性垫230的可变形的特点，进一步将压缩腔110内介质挤压出去，尽可能地排净压缩腔110内的介质，提高压缩机构10在压缩工作时的容积效率。
参阅图2、图3及图4，一实施例中，弹性垫230背向于活塞本体210的表面上开设有多个形变槽231。由于在压缩过程中，弹性垫230能够抵接于压缩腔110开设有排出通道122的内壁上，在挤压的过程中弹性垫230会变形。通过设置形变槽231能够提高弹性垫230的形变程度，为弹性垫230的变形提供变形余量，进一步保证排净压缩腔110内的介质，保证提高压缩机构10的容积效率。
具体地，弹性垫230为圆盘状，多个形变槽231绕着弹性垫230中心线间隔设置。进一步地，相邻两个形变槽231通过一连通槽连通，进一步保证弹性垫230在挤压变形过程中的形变余量。
一实施例中，活塞本体210朝向排出通道122的端面上开设有安装槽211，弹性垫230上设置有安装部232，安装部232卡设于安装槽211内。通过设置安装部232与安装槽211，能够保证弹性垫230在活塞本体210上安装的可靠性。
一实施例中，活塞杆220的端面上开设有容纳槽212，安装槽211开设于容纳槽212的底壁上，弹性垫230的部分位于容纳槽212内。当安装部232卡设于安装槽211内时，能够使得弹性垫230部分位于容纳槽212，能够进一步保证弹性垫230在活塞本体210上设置的稳定性。
一实施例中，安装槽211的内壁上形成有环形卡槽，安装部232的外壁上形成有环形卡设凸起，安装部232设置于安装槽211内以使所述环形卡设凸起设置于所述环形卡槽内。利用环形卡设凸起与环形卡槽能够有效限制弹性垫230 朝远离活塞本体210的方向活动。在其他实施例中，安装部232还可以通过卡勾结构勾设在安装槽211的内壁上。
一实施例中，安装部232一体成型在弹性垫230上，环形卡设凸起一体成型在安装部232的外壁上，安装部232、环形卡设凸起及弹性垫230均为弹性可变形体。通过将安装部232、环形卡设凸起及弹性垫230均一体成型在一起，能够提高各个部件之间连接的可靠性，同时也能够简化工艺。
一实施例中，弹性垫230为耐高温橡胶垫。耐高温橡胶垫不仅能够保证弹性垫230的变形，还能够保证在高温环境中工作的可靠性。在其他实施例中，弹性垫230还可以由其他能够变形的弹性材质制成。
一实施例中，活塞组件200还包括配合环240及锁定件250，活塞本体210上开设有连接孔213，配合环240穿设于连接孔213内，活塞杆220的一端穿设于配合环240内，锁定件250安装于活塞本体210上并锁紧活塞杆220。由于活塞杆220通过配合环240连接在活塞本体210上，避免了活塞杆220与活塞本体210之间的直接接触，能够降低活塞杆220的作用力作用在活塞本体210上而导致活塞本体210的变形。
在本实施例中，锁定件250可以为螺栓，螺栓的头部抵接于活塞本体210上，螺栓的杆部穿过配合环240并穿设于活塞杆220内，实现活塞本体210与活塞杆220的连接。
一实施例中，活塞本体210的外壁上形成有绕周向设置的环形凹槽214，环形凹槽214内设置有格莱圈260。具体地，格莱圈260包括O型圈及聚四氟乙烯环，聚四氟乙烯环套设于O型圈外。聚四氟乙烯环为自润滑材料，能够减少与压缩腔110内壁的摩擦。当聚四氟乙烯环磨损时，O型圈能够起一定的补偿作用，保证密封效果，延长使用寿命。
在其他实施例中，环形凹槽214还可以仅设置密封环，只要能够保证活塞本体210与压缩腔110内壁之间的密封效果即可。
参阅图2及图5，一实施例中，压缩机构10还包括阀组件300，阀组件300包括阀块310及阀片320，阀片320包括连接部321及与连接部321连接的排出部322，排出部322抵接在所述排出通道122远离压缩腔110的出口处，阀块310设置于阀片320背向于排出通道122的一侧，并与连接部321连接，阀块310对位于排出部322的侧面形成为限位斜面312，以使限位斜面312与排出部322间隔设置。
由于限位斜面312与排出部322间隔设置，排出介质时，介质能够通过排出通道122将阀片320的排出部322朝阀块310的限位斜面312的方向推动，以使排出部322抵接于限位斜面312上，进而使得排出部322解除对排出通道122的密封，以使介质能够排出。当排气完成后，排出部322利用阀片320的自身弹力恢复对排出通道122的覆盖。由于在排出的过程中，排出部322弹性变形后能够贴合在限位斜面312上，限位斜面312能够对排出部322起到限位支撑作用，进而能够提高阀片320的使用寿命。
参阅图1及图2，一实施例中，压缩缸100上形成有两个进入通道120及两个排出通道122，其中一进入通道120与一排出通道122与活塞本体210一侧的压缩腔110连通，另一进入通道120与另一排出通道122与活塞本体210相背对的另一侧的压缩腔110连通。
在使用时，活塞本体210朝一侧压缩时，该侧排出介质，而另一侧介质进入，反过来，当活塞本体210朝另一侧压缩时，该侧排出介质，而一侧介质进入。通过设置两个进入通道120与两个排出通道122，能够实现双向做功压缩，以使活塞本体210朝两个方向的往复移动过程均能够实现做功。
具体地，每一所述排出通道122均对应设置有一所述阀组件300。通过设置阀组件300保证介质排出的可靠性。
一实施例中，活塞本体210相背对的两端上均设置有弹性垫230。由于活塞本体210朝两个方向移动均进行做功，进而使得两个弹性垫230分别朝向两个排出通道122，进一步保证两侧做功压缩的容积效率。
参阅图1、图2及图6，一实施例中，压缩缸100包括缸本体130、第一构件140及第二构件150，压缩腔110形成在缸本体130内，且缸本体130的一侧开口，第一构件140设置于缸本体130的开口侧，且一进入通道120与一排出通道122均形成在第一构件140上，第一构件140上形成有与排出通道122连通的第一排出腔142，一阀组件300设置于第一排出腔142内并设置于与第一排出腔142连通的排出通道122处。活塞本体210能够通过缸本体130的开口侧设置于压缩腔110内，而第一构件140内的第一排出腔142能够为阀组件300的设置提供安装空间。
具体地，第一构件140背向于缸本体130的一侧还开设由于安装腔144，第一构件140上还开设有连通孔146，连通孔146连通压缩腔110与安装腔144，活塞杆220远离活塞本体210的一端穿过连通孔146并穿设于安装腔144内。
在本实施例中，压缩机构10还包括动力组件，动力组件设置于安装腔144内，并与活塞杆220连接，动力组件用于驱动活塞杆220往复移动，以实现活塞本体210在压缩腔110内的往复移动。
一实施例中，缸本体130与所述开口相对的侧壁上开设有另一进入通道120与另一排出通道122，第二构件150设置于缸本体130背向于第一构件140的一侧，第二构件150内形成有进入腔151及第二排出腔152，进入腔151与另一进入通道120连通，第二排出腔152与另一排出通道122连通，另一阀组件300 设置于第二排出腔152内并设置于与第二排出腔152连通的所排出通道122处。通过设置第二构件150便于实现另一阀组件300的安装，保证介质通过另一排出通道122排出的稳定性。
