参阅图1至图3，本发明一实施例中的动力设备10，至少能够保证压缩过程的稳定性，提高压缩的可靠性。具体地，动力设备10包括往复组件100、第一压缩组件200及动力源300，第一压缩组件200设置于动力源300与往复组件100之间。
在本实施例中，往复组件100包括动力轴110及往复件120，往复件120与动力轴110传动配合；第一压缩组件200包括第一压缩缸210及第一活塞220，第一压缩缸210内形成有第一压缩腔211，第一压缩缸210上开设有第一进入通道212及第一排出通道213，第一进入通道212与第一排出通道213均与第一压缩腔211连接，第一活塞220设置于第一压缩腔211内，且第一活塞220连接于往复件120；动力源300、第一压缩组件200及往复 件120沿动力轴110的轴线依次布置，第一压缩缸210朝向往复件120的一侧开设有第一驱动孔214(如图4所示)，第一压缩缸210朝向动力源300的一侧开设有第二驱动孔215(如图4所示)，第一活塞220上开设有第一连通孔221(如图4所示)，动力轴110的一端依次穿过第一驱动孔214、第一连通孔221及第二驱动孔215与动力源300连接，动力源300用于驱动动力轴110转动，以通过往复件120带动第一活塞220沿动力轴110的轴线方向往复移动。
上述动力设备10，由于动力源300、第一压缩组件200及往复件120沿动力轴110的轴线依次布置，动力轴110的一端依次穿过第一压缩缸210体的第一驱动孔214、第一活塞220的第一连通孔221及第一压缩缸210体的第二驱动孔215与动力源300连接。使用时，动力源300驱动动力轴110转动，动力轴110通过往复件120带动第一活塞220沿动力轴110的轴线方向往复移动，以使气体或流体等介质由第一进入通道212进入第一压缩腔211内经第一活塞220压缩后由第一排出通道213排出。上述第一压缩组件200设置于与动力源300与往复件120之间，且第一压缩缸210体及第一活塞220串在动力轴110上，进而保证第一压缩组件200设置的可靠性。同时，在驱动第一活塞220往复移动时，使得第一活塞220的移动发生在动力源300与往复件120之间，且保证稳定地沿着动力轴110的轴线移动，进一步保证第一活塞220移动的可靠性，以保证动力设备10压缩或泵出过程的稳定。

使用时，当第一活塞220朝向动力源300方向移动时，能够压缩第一活塞220朝向动力源300一侧的第一压缩腔211内的气体或流体介质，以使压缩的介质由与该侧连通的第一排出通道213排出；同时第一活塞220朝向往复件120的一侧通过与该侧第一压缩腔211连通的第一进入通道212进介质。当第一活塞220朝向往复件120的方向移动时，压缩第一压缩腔211朝向往复件120一侧的介质，以使该侧的介质通过与该侧连通的第一排出通 道213排出，而第一活塞220朝向动力源300一侧的第一压缩腔211内通过与该侧连通的第一进入通道212进介质。因此通过两个第一进入通道212与两个第一排出通道213，实现第一活塞220朝一个方向移动时，一侧进介质另一侧压缩排出，有效提高压缩效率。
在本实施例中，一第一进入通道212与一第一排出通道213开设于第一通气件230上，另一第一进入通道212与另一第一排出通道213开设于第二通气件250上。具体地，第一通气件230与第二通气件250的结构一致，便于进一步降低成本，提高通用性。

具体地，第一导向孔216开设于第一通气件230上。
具体地，第一活塞220上开设有第一连接孔，导杆121的一端穿设于第一连接孔内并与第一活塞220连接。

动力轴110转动时，移动体124能够在往复槽111内移动，使得移动体124能够在呈曲线形槽的波峰与波谷之间的运动，以实现移动体124沿着动力轴110的轴线方向往复移动的目的，进而通过导杆121带动第一活塞220沿着动力轴110的轴线方向往复移动。动力轴110的旋转运动转化为往复套122沿动力轴110轴线的直线运动，不会出现曲柄结构或偏心驱动结构的偏摆交问题，做功稳定性更好。

进一步地，移动体124与配合套的内壁之间设置有多个可滚动的滚珠。在本实施例中，多个滚珠抵接于移动体124背向于动力轴110的一侧。当移动体124相对于配合套滚动时，利用多个滚珠进一步降低滚动摩擦力，进一步提高移动体124滚动的顺滑程度，保证传动的稳定性。

一实施例中，第二压缩缸410朝向往复件120的一侧还开设有第三驱动孔414，动力轴110进一步穿设于第三驱动孔414，并能够在第三驱动孔414内转动。通过动力轴110穿设于第三驱动孔414内，能够进一步提供动力轴110转动的稳定性。具体地，动力轴110的动力杆112进一步穿设于第三驱动孔414，并能够在第三驱动孔414内转动。在本实施例中，第三驱动孔414开设于第一连接件430上。
一实施例中，第二进入通道412与第二排出通道413均为两个，一第二进入通道412与一第二排出通道413与第二活塞420一侧的第二压缩腔411连通，另一第二进入通道412与另一第二排出通道413与第二活塞420相背对的另一侧的第二压缩腔411连通。
当第二活塞420朝向往复件120方向移动时，能够压缩第二活塞420朝向往复件120一侧的第二压缩腔411内的介质，以使压缩的介质由与该侧连通的第二排出通道413排出；同时第二活塞420背向于往复件120一侧通过与该侧第二压缩腔411连通的第二进入通道412进介质至第二压缩腔411。当第二活塞420向背向于往复件120的方向移动时，压缩第二压缩腔411背向往复件120一侧的介质，以使该侧的介质通过与该侧连通的第二排出通道413排出，而第二活塞420朝向往复件120一侧的第二压缩腔411内通过与该侧连通的第二进入通道412进入。因此通过两个第二进入通道412与两个第二排出通道413，实现第二活塞420朝一个方向移动时，一侧进介质一侧压缩排出，有效提高压缩效率。第一压缩组件200与第二压缩组件400相配合，实现同一时刻二进介质与二压缩排出。
在本实施例中，一第二进入通道412与一第二排出通道413开设于第一连接件430上，另一第二进入通道412与另一第二排出通道413开设于第二连接件450上。具体地，第一连接件430与第二连接件450的结构一致，便于进一步降低成本，提高通用性。进一步地，第一连接件430、第二连接件450、第一通气件230与第二通气件250的结构均一致，便于更进一步降低成本，提高通用性。
在其他实施例中，第二压缩组件400还可以为二级压缩组件，实现其他的二级压缩。具体地，第二活塞420上开设有第二通气孔，所述第二通气孔用于连通第二活塞420相背对两侧的第二压缩腔411，第二通气孔处设置有第二单向阀，第二单向阀的流通方向为第二进入通道412至第二排出通道413的方向。例如，第二活塞420朝往复件120的方向移动时，能够将朝向往复件120一侧的第二压缩腔411内的介质通过第二通气孔压缩第二活塞420背向往复件120一侧的第二压缩腔411内。第二活塞420进一步朝背向往复件120的一侧移动，以进一步压缩该侧的第二压缩腔411内的介质并通过第二排出通道413排出，此时第二进入通道412进介质至朝向往复件120一侧的第二压缩腔411朝内，实现其他的二级压缩。
一实施例中，第二压缩缸410朝向往复件120的一侧还开设有与第二压缩腔411连通的第二导向孔415，导杆121的另一端穿过第二导向孔415并穿设于第二压缩腔411内与第二活塞420相连接。通过导杆121能够进一步带动第二活塞420往复移动，且由于导杆121进一步穿设于第二导向孔415内，进而第二导向孔415还能够进一步为导杆121带动第二活塞420的移动提供导向作用，更进一步提高导杆121带动第一活塞220与第二活塞420移动的稳定性。
具体地，第二导向孔415开设于第一连接件430上。
具体地，第二活塞420上开设有第二连接孔，导杆121的一端穿设于第二连接孔内并与第二活塞420连接。
一实施例中，第二导向孔415的数量与导杆121的数量相一致，每一导杆121对应穿过一第二导向孔415与第二活塞420连接。通过设置至少两个导杆121与第二活塞420连接，能够提高驱动第二活塞420往复移动的可靠性。
一实施例中，安装壳130安装于第一压缩缸210与第二压缩缸410之间。利用第一压缩缸210与第二压缩缸410之间的空间设置安装壳130，保证安装壳130设置的稳定性。具体地，安装壳130设置于第一连接件430与第一通气件230之间。进一步地，安装壳130朝向第一连接件430的一侧上也开设有穿孔134，该穿孔134与第二导向孔415对应连通，导杆121进一步穿设于该穿孔134内。
参阅图1至图3，一实施例中，第一压缩组件200及往复组件100为两个，两个第一压缩组件200及两个往复组件100沿动力轴110的轴线分别布置于动力源300相背对的两侧。动力源300能够同步驱动两侧的往复组件100的往复件120同步移动，进而实现两个第一压缩组件200同步压缩，进一步提供压缩效率。
一实施例中，第二压缩组件400为两个，两个第二压缩组件400分别设置于两个往复组件100背向于与之连接的第一压缩组件200的一侧。动力源300能够同步驱动两侧的往复组件100的往复件120同步移动，进而实现两侧的第一压缩组件200与第二压缩组件400同步压缩，使得动力设备10在一个往复移动行程内，实现同步四进介质与四压缩排出。上述动力设备10能够用于大气量的压缩排气场景中，有效提高压缩气量，提高压缩效率。
参阅图7，在另一实施例中，第一压缩组件200、第二压缩组件400及往复组件100还可以均为一个。或者，第一压缩组件200为两个，往复组件100为两个，第二压缩组件400可以为一个。
或者在其他实施例中，还可以在第二压缩组件400背向于第一压缩组件200的一侧继续设置往复组件100及压缩组件，该压缩组件的结构可以与第二压缩组件400的结构一致，进一步增大动力设备10的压缩气量。
一实施例中，所述动力设备还包括储气袋，所述储气袋连接于第一压缩组件200的第一排出通道213处，第一排出通道213与所述储气袋内的空间连通。压缩后气体可以通过第一排出通道213排入到储气袋内，且由于储气袋为柔性的特点，在不使用时，能够有效降低储气袋对空间的占用，进一步有利于动力设备10的小型化设计。
具体地，第二压缩组件400的第二排出通道413处设置有储气袋，第二排出通道413与所述储气袋内的空间连通。进一步地，第二排出通道413与第一排出通道213同时连接于一个储气袋。
