本发明所采用的技术方案是：一种气路系统，包括储气罐、设置在储气罐上的供气管路以及设置在供气管路上的若干个供气支路，在供气支路上设置有二位三通电磁阀，在供气支路的末端设置有试剂盒。
进一步的，还包括与储气罐连通的气泵，在所述储气罐上设置有检测储气罐内压力的压力传感器，压力传感器检测的压力值反馈给气泵。
进一步的，试剂盒与二位三通电磁阀的工作口连通，二位三通电磁阀的进气口与供气管路连通。
进一步的，所述试剂盒包括盒体、设置在盒体下端的出液管、设置在出液管内的密封胶垫、设置在密封胶垫上的密封塞以及用于驱动密封塞在出液管内移动的驱动装置，在所述密封胶垫的中部设置有出液口，所述密封塞与出液口相对应。
进一步的，所述驱动装置为电磁线圈，密封塞采用磁性材质，电磁线圈通电将密封塞抬起，失电后再自身重力作用下密封塞与密封胶垫接触，将出液口密封。
进一步的，所述密封塞包括密封球体以及固定设置在密封球体上方的磁棒。
进一步的，在所述密封胶垫的顶端设置有与密封球体相对应的球形槽，出液口位于球形槽的下端。
所述驱动装置还包括设置在出液管上用于吸引密封塞向下运动的环形磁铁。
 有益效果
本发明的积极效果为：本发明在试剂盒与供气管路之间设置二位三通电磁阀，通电时，使试剂盒与供气管路直接连通，为试剂盒内提供压力，将试剂压出，而断电时，试剂盒与排气口连通，试剂盒泄压，使其内部的压力与大气相同，防止试剂盒内因压力升高而升温。通过设置在储气罐上的压力传感器检测储气罐内压力，并反馈给气泵，调整气泵的供气量，使储气罐内压力保持恒定，为供气管路提供稳定压力。
 附图说明
图1为本发明结构示意图。
图2为本发明试剂盒结构示意图。
 本发明的实施方式
如附图1所示，本发明包括气泵3、与气泵3连通的储气罐1、设置在储气罐1上的供气管路4以及设置在供气管路4上的若干个供气支路5，在供气支路5上设置有二位三通电磁阀6，在供气支路5的末端设置有试剂盒7，所述储气罐1上设置有检测储气罐1内压力的压力传感器2，压力传感器2检测的压力值反馈给气泵3。
根据二位三通电磁阀6的工作原理，其具有进气口、排气口以及工作口，通电时，进气口与工作口连通，失电时，排气口与工作口连通。因此工作口与试剂盒7连通，进气口与供气管路4连通。当需要从试剂盒内取液时，二位三通电磁阀6通电，经供气管路4向试剂盒7内供气，通过压力将试剂盒内的液体压出。取液完成后，二位三通电磁阀6断电，试剂盒7与排气口连通，从而与大气相通，实现泄压。
所述试剂盒7包括盒体701、设置在盒体701下端的出液管703、设置在出液管703内的密封胶垫707、设置在密封胶垫707上的密封塞以及用于驱动密封塞在出液管703内移动的驱动装置，在所述密封胶垫707的中部设置有出液口708，所述密封塞与出液口708相对应。
所述驱动装置为电磁线圈704，密封塞采用磁性材质，电磁线圈704通电将密封塞抬起，失电后再自身重力作用下密封塞与密封胶垫707接触，将出液口708密封。密封塞包括密封球体705以及固定设置在密封球体705上方的磁棒706。同时在出液管703的外侧端上设置有用于吸引密封塞向下运动的环形磁铁709。电磁线圈704对密封塞的吸力应足够大，以克服密封塞自身的重力、环形磁铁709对密封塞的吸引力以及内部压力，从而实现密封塞的向上运动。
利用电磁线圈704得电时，对磁棒706产生引力，带动磁棒706向上运动，从而使密封球体705与密封胶垫707脱离，出液口708与盒体701内部连通，从而实现盒内液体的流出。而电磁线圈704失电时，对磁棒706失去作用力，在自身重力以及环形磁铁作用下，密封球体705下降，将出液口708封死，防止液体流出。
在所述密封胶垫707的顶端设置有与密封球体705相对应的球形槽，出液口708位于球形槽的下端，利用球形槽与密封球体705配合实现密封，密封效果更好。
本发明通过电磁力来控制试剂盒的打开和关闭，无需人工打开试剂盒提取试剂，实现了自动化操作，而再配合二位三通电磁阀6，在实现自动化取液的同时，也可以保证整个管内的保持恒定的温度和压力。
