当保温背包处于初始状态时，复位弹簧处于原长，密封筛在复位弹簧的作用下，带动密封条置于连接槽与第一通槽的连通处，以使得连接槽与第一通槽不连通的状态。
当需要对保温背包进行降温处理时，外部降温设备与连接槽连接，外部降温设备发出冷风，冷风作用于密封筛，使得密封筛朝靠近保温容腔的方向移动，复位弹簧处于压缩状态，且连接槽与第一通槽连通，冷风依次经过连接槽、第一通槽以及第二通槽，以进入保温容腔进行降温。

如图1～10所示的具体实施例，本实施例提供的一种保温背包，可以运用在室内或者户外，也可以在紧急情况下使用，需要使用时，可直接带走背包，方便快捷，且当需要进行保温背包内的产品进行冷却降温时，无需将产品拿出，且快速进行降温，操作方便。
请参阅图1至图3，上述的一种保温背包，包括背包本体10以及转接组件30，背包本体10内设有保温容腔102，背包本体10上设有连接孔101，连接孔101与保温容腔102连通，则可以通过外部冷却设备与保温容腔102连通，对保温容腔102内的产品进行冷却，无需拿出该产品。
更进一步地，请参阅图4，上述的转接组件30插设在连接孔101内，转接组件30包括固定架、密封筛32以及复位组件，密封筛32的外周朝外凸设有密封条321，固定架内设有连接槽316以及第一通槽312，第一通槽312与保温容腔102连接，密封筛32与复位组件连接；当转接组件30与外部降温设备连接时，密封筛32朝靠近保温容腔102的内部的方向移动，以使得连接槽316与第一通槽312连通，当转接组件30未与外部降温设备连接时，密封筛32朝远离保温容腔102的内部的方向移动，密封条321抵接连接槽316的下端，以使得连接槽316与第一通槽312未连通。利用复位组件带动密封筛32移动，实现连接槽316与第一通槽312的连通与隔断，进而实现对保温容腔102内的产品进行冷却或密封，结构简单，且操作方便。
连接槽316位于第一通槽312的上端，且连接槽316的宽度小于第一通槽312的宽度，且密封条321的宽度大于连接槽316的宽度，连接槽316与第一通槽312为阶梯槽，密封筛32可通过移动后，插设在连接槽316，以密封该连接槽316，密封条321位于密封筛32的下半部分的外端，可以密封连接槽316，可以提高未借助外部降温设备进行冷却时第一通槽312与连接槽316的未连通的密闭性，以确保 保温容腔102内的保温效果。
在一实施例中，请参阅图6，上述的固定架包括架体31以及连接于架体31内部的卡勾，卡勾与复位组件连接，架体31内设有第一通槽312以及连接槽316，架体31与连接孔101抵接，卡勾置于第一通槽312的内壁上，借助卡勾将复位组件固定。
具体地，架体31的外周设有限位环片311，该限位环片311抵接在连接孔101的外端，由此使得架体31与连接孔101抵接，借助卡勾与复位组件的连接，实现复位组件的固定。
在一实施例中，请参阅图6与图7，上述的复位组件包括连接盘34以及复位弹簧35，连接盘34与卡勾连接，复位弹簧35的下端与连接盘34连接，复位弹簧35的上端与密封筛32连接，连接盘34与连接孔101抵接。
该连接盘34的直径大于连接孔101的直径，以使得连接盘34可以抵接在连接孔101靠近保温容腔102的一端，借此将复位弹簧35以及密封筛32置于第一通槽312与连接槽316内。
在一实施例中，请参阅图6，上述的连接盘34的上端朝上延伸有连接环342，连接环342内设有若干个卡槽341，卡勾连接在卡槽341内。利用卡槽341与卡勾的连接，实现连接盘34与架体31的连接。
具体地，上述的密封条321上设有若干个缺口322，上述的卡勾包括连接板314以及倒钩段315，该连接板314连接于上述的第一通槽312内，倒钩段315连接于连接板314的下端，且上述的连接板314置于缺口322内，倒钩段315插设在卡槽341内，实现密封筛32的移动过程中不会因为连接盘34与架体31的连接而造成干扰。
在本实施例中，上述的缺口322的个数为四个，上述的卡勾的个数为四个。
在一实施例中，请参阅图5，上述的连接盘34的外端连接有固定片33，固定片33抵接在连接孔101的外端，固定片33内设有插孔，连接盘34插设在插孔内，该固定片33靠近连接盘34的一侧呈弧形布置，该弧形的弧度与连接盘34的外弧度一致。
具体地，插孔的内壁朝内凸设有若干个连接块331，连接块331与架体31连接， 相邻连接块331之间设有第二通槽，第一通槽312、第二通槽以及保温容腔102连通。
另外，架体31内还设有连接柱313，该连接柱313置于第一通槽312内，且连接柱313与连接块331连接，固定片33的直径大于连接孔101的直径，插孔的直径大于连接孔101的直径，连接块331的存在，可以抵接这插孔，以使得连接盘34不会脱离该连接孔101，进而实现连接盘34的固定。该连接柱313通过紧固件与连接块331连接，该紧固件包括但不局限于螺钉。
如图7与图8，当出现紧急情况时，可以随时将制冷好的产品随时取走和随时保温，当医院有需要长期保鲜和保温的东西，当温度降低到不是保鲜温度时，如图7所示，可以将冷风机的管口插入连接槽316处，以借助冷风对密封筛32的作用，推动密封筛32朝靠近连接盘34的方向移动，从而使得密封条321离开连接槽316与第一通槽312的连通处，使得冷风可以经过连接槽316、第一通槽312和第二通槽，进入到保温容腔102内进行降温。另外，如图8所示，未进行降温的时候，密封筛32密封连接槽316与第一通槽312的连通处，以使得整个保温背包具备保温的功能。出现紧急情况时，可以立即背起保温背包，即刻出发，在野外，保温背包可以放在车里保温，也可以立取立走。
在本实施例中，上述的保温容腔102内设有保温层，所述保温层上设有通孔，该通孔与连接孔101连通，将架体31置于通孔与连接孔101内，装上密封筛32以及复位弹簧35后，再将固定片33固定即可，拆装均方便。上述的保温层使用的是真空隔热加高密度发泡材料。
在一实施例中，请参阅图9，上述的密封筛32的上端还连接有连接件，连接件包括连接管40，所述连接管40的侧壁上设有条形槽41，所述连接管40靠近所述密封筛32的一端设有封片42。
该连接管40与冷风机连接，当冷风机工作时，连接管40推动密封筛32朝下移动，使得条形槽41、连接槽316、第一通槽312以及第二通槽连通，冷风从连接管40通过固定架到保温容腔102内，当取出冷风机时，复位弹簧35将密封筛32向上顶使其密封，此时第一通槽312和连接槽316密合，从而产生快速降温和保温的效果。
请参阅图10，上述的背包本体10上连接有温度显示屏20，保温容腔102内连接有温度传感器，保温背包还包括主控芯片U1，温度显示屏20以及温度传感器分别与主控芯片U1连接。
具体地，主控芯片U1的型号为AT89C2051。
随时检测保温容腔102内的温度，当温度高的时侯可以提醒使用者将要保温的产品降温。
该主控芯片U1还连接有纽扣3V电池，此时主控芯片U1和温度传感器接通电源工作开始。温度传感器根据温度产生变化，此时温度传感器的阻值产生变化，通过温度传感器的2端脚，到主控芯片U1的P17端脚，然后经过主控芯片U1的P16端脚、P15端脚、P14端脚、P13端脚、P12端脚、P11端脚、P10端脚后，分别通过电阻R7、R6、R5、R4、R3、R2、R1，到达温度显示屏20以显示保温容腔102里的温度，从而实现保温容腔102的温度的实时检测。
在本实施例中，上述的温度传感器的型号为DS1820，上述的温度显示屏20为但不局限于DPY 8型脉槽显示器。
上述的背包本体10的外周连接有背带11，且背包本体10的上端连接有提带12。
上述的一种保温背包，通过在背包本体10上设置连接孔101，在连接孔101内插设转接组件30，借助密封筛32、密封条321以及复位弹簧35，实现连接槽316与第一通槽312的连通与隔断，在需要借助外部冷却设备进行保温容腔102内部的降温时，外部冷却设备输出的冷风作用于密封筛32，以使得密封条321脱离连接槽316与第一通槽312的连通处，冷风进入保温容腔102，否则，则密封条321密封在连接槽316与第一通槽312的连通处，将保温容腔102密封，实现无需取出内部产品便可快速进行降温，且可以起到保温的效果，适用于紧急情况，操作方便。
在一实施例中，还提供了一种保温背包的工作方法，该工作方法使用了上述的一种保温背包，包括：
当保温背包处于初始状态时，复位弹簧35处于原长，密封筛32在复位弹簧35的作用下，带动密封条321置于连接槽316与第一通槽312的连通处，以使得连接槽316与第一通槽312不连通的状态。
当需要对保温背包进行降温处理时，外部降温设备与连接槽316连接，外部降温设备发出冷风，冷风作用于密封筛32，使得密封筛32朝靠近保温容腔102的方向移动，复位弹簧35处于压缩状态，且连接槽316与第一通槽312连通，冷风依次经过连接槽316、第一通槽312以及第二通槽，以进入保温容腔102进行降温。
需要说明的是，所属领域的技术人员可以清楚地了解到，上述一种保温背包的工作方法的具体实现过程，可以参考前述的一种保温背包实施例中的相应描述，为了描述的方便和简洁，在此不再赘述。
上述仅以实施例来进一步说明本申请的技术内容，以便于读者更容易理解，但不代表本申请的实施方式仅限于此，任何依本申请所做的技术延伸或再创造，均受本申请的保护。本申请的保护范围以权利要求书为准。
