具体实施方式
为详细说明本发明的技术内容、构造特征、所实现目的及效果，以下结合实施方式并配合附图详予说明。
第一实施例
请参阅图1至图3所示，本实施例的洁净厌氧箱包括外箱体10、内箱体20和加热装置，其中，该内箱体20置于外箱体10内，且外箱体10的内壁与内箱体20的外壁之间形成空气夹套11，内箱体20呈中空结构并形成收容腔21，收容腔21与空气夹套11相互隔绝并均呈密闭结构。加热装置用于加热空气夹套11内的气体，以确保空气夹套11内的气体加热并能恒维持在预设温度，从而对收容腔21进行间接加热。可以理解的是，本实施例的收容腔21与空气夹套11相互隔绝并均呈密闭结构，可分别对收容腔21和空气夹套11独立注入并密封气体，并确保收容腔21和空气夹套11之间的气体不存在交互。
较佳者，外箱体10和内箱体20分别设有舱门，依次打开外箱体10的舱门和内箱体20的舱门以将待测试产品(图中未示)置入收容腔21内， 这里的待测试产品一般为高精密电子元器件。当然，在其他实施方式中，外箱体10的舱门和内箱体20的舱门可以为一体式结构，即打开外箱体10的舱门时，即能直接将待测试产品置入收容腔21内，并在关闭外箱体10的舱门后，能保持收容腔21和空气夹套11的独立密封。
该外箱体10分别开设有连通空气夹套11的第一进气口12和第一排气口13，气体可选择地通过第一进气口12注入空气夹套11并从第一排气口13流出，通过加热装置控制空气夹套11内的气体温度，从而实现空气夹套11对收容腔21温度的间接调整。
可以理解的是，第一进气口12通过对应的管道接入诸如鼓风机等外部装置的吹风口，第一排气口13通过对应的管道伸至洁净厌氧箱外或其他的气体回收装置内，较佳者，这里注入空气夹套11的气体一般为空气。当需要对收容腔21进行间接加热时，第一进气口12和第一排气口13均需处于关闭状态，再通过加热装置对空气夹套11内的气体进行加热；当需要对收容腔21进行快速降温时，第一进气口12和第一排气口13均需处于打开状态，通过外部装置不断从第一进气口12对空气夹套11注入气体(一般为常温空气或较冷空气)，并使空气夹套11内的气体不断沿第一排气流出，以对空气夹套11内原来的气体进行置换，并使新注入的气体充盈空气夹套11，此时，由于空气夹套11的气体温度较低，从而能够对收容腔21进行快速降温。
较佳地，该内箱体20分别开设有连通收容腔21的第二进气口22和第二排气口23，惰性气体可通过第二进气口22注入收容腔21并从第二排气口23流出，从而使收容腔21内成为厌氧环境，以供测试使用。可以理解的是，第二进气口22通过对应的管道接入惰性气体供应装置的出气口，第二排气口23通过对应的管道接入惰性气体供应装置的回收口，较佳者，这里注入收容腔21的惰性气体一般为氮气。
使用时，通过惰性气体供应装置不断从第二进气口22对收容腔21注入惰性气体，并使收容腔21内的惰性气体不断沿第二排气流出，以对收容腔21内原来的气体进行置换，并使新注入的惰性气体充盈收容腔21，从而通过充盈惰性气体以使收容腔21成为厌氧环境。在空气夹套11对收容 腔21内的温度进行间接提升的情况下，无需通过不断对收容腔21内注入具有预设温度的氮气即可维持收容腔21内的厌氧环境温度，从而有效降低惰性气体的用量，降低使用成本。
进一步地，本实施例的洁净厌氧箱还包括第一循环装置30和第一循环装置70，第一循环装置30用于带动收容腔21内的惰性气体循环流动，以提升惰性气体置换效率、惰性气体的均匀性及收容腔21内温度的均匀性。
第一循环装置70用于带动空气夹套11内的气体循环流动，以提升气体的置换效率和空气夹套11内各向的温度均匀性，以保证空气夹套11能够均匀地间接调整收容腔21的温度。
更进一步地，本实施例的洁净厌氧箱还包括壳体60，外箱体10置于壳体60内，且壳体60的内壁与外箱体10的外壁之间形成保温层61，保温层61与收容腔21、空气夹套11相互隔绝。具体地，保温层61填充有保温材料，当然，在其他实施方式中，保温层61内注有空气或呈中空状态。通过增设保温层61，能够有效降低空气夹套11的热量散失速度，从而能够进一步避免外部环境对环境测试造成的影响，有效提升测试准确度。
较佳地，壳体60上设有舱门，壳体60的舱门与外箱体10的舱门和内箱体20的舱门为一体式结构，即打开壳体60的舱门时，即能直接将待测试产品置入收容腔21内，并在关闭壳体60的舱门后，能保持保温层61、收容腔21和空气夹套11的独立密封。
更进一步地，本实施例的第一进气口12、第一排气口13、第二进气口22和第二排气口23分别设有独立控制的单向阀门，一方面限制对应气体的流动方向，另一方面，当需要对收容腔21进行间接加热时，分别关闭第一进气口12和第一排气口13的单向阀门，以使空气夹套11无法与外部流通，此时，通过加热装置对空气夹套11的气体进行加热处理，有效节省用电量；当需要对收容腔21进行快速降温时，分别打开第一进气口12和第一排气口13的单向阀门，通过外部装置不断从第一进气口12对空气夹套11注入气体，并使空气夹套11内的气体不断沿第一排气流出，以对空气夹套11内原来的气体进行置换，并使新注入的气体充盈空气夹套11，从而快速降低空气夹套11的气体温度，从而实现对收容腔21间接快速降温； 当惰性气体完全置换完收容腔21的原有气体后，可以分别关闭第二进气口22和第二排气口23的单向阀门并停止对收容腔21的惰性气体注入，有效节省惰性气体用量和用电量，从而大大降低使用成本。
可以理解的是，这里的第一进气口12、第一排气口13、第二进气口22和第二排气口23的单向阀门可以通过人工控制，也可以通过电子自动控制，在此不做限定。
下面对本实施例的洁净厌氧箱的使用进行详细说明：
1、将待测试产品置于收容腔21内。
2、启动第一循环装置30，并同时往收容腔21注入惰性气体，第一循环装置30带动惰性气体在收容腔21内循环流动，以快速置换收容腔21内的原有气体，当惰性气体完全充盈收容腔21后，关闭第二进气口22和第二排气口23对应的单向阀门，从而使收容腔21保持为厌氧环境。
3、启动第一循环装置70和加热装置，加热装置加热空气夹套11内的空气，第一循环装置70带动空气夹套11内的空气循环流动，以提升空气夹套11内的空气温度的各向均匀性，从而能够对收容腔21的温度进行调整。其中，步骤2和步骤3可以同时进行。
4、当试验结束需要降温取出待测试产品时，打开第一进气口12和第一排气口13对应的单向阀门，并往空气夹套11注入大量低温空气或常温空气，以置换空气夹套11内的原有空气，同时启动第一循环装置70，以带动比预设温度的温度更低的空气或常温空气在空气夹套11内循环流动，提升置换速度，此时，套腔内的空气温度急剧下降，以间接降低收容腔21的温度，从而实现对收容腔21的降温操作；
5、当收容腔21内的温度降低至预设值时，打开舱门，取出待测试产品，完成试验。
第二实施例
请参阅图4至图6所示，本实施例与第一实施例的区别在于，本实施例的洁净厌氧箱还包括过滤装置，该过滤装置用于过滤收容腔21内的杂质、灰尘等物质。较佳地，该过滤装置包括两个过滤器40，所述第一循环装置30带动所述收容腔21内的惰性气体循环流动以形成循环回路，两所 述过滤器40分别间隔设于所述循环回路构成的路径上，以在循环回路的不同路径点上过滤杂质、灰尘，提升收容腔21内的洁净度。
进一步地，两所述过滤器40中的一者临近所述第二进气口22，以进一步过滤从所述第二进气口22流入所述收容腔21的惰性气体的杂质，另一者临近所述第二排气口23以进一步过滤通过所述第二排气口23从所述收容腔21流向外部环境的惰性气体的杂质。通过第一循环装置30与过滤装置的配合，能够对本实施例的惰性气体供应装置与收容腔21的惰性气体交互实现洁净，便于等于惰性气体进行回收及循环利用。需要说明的是，本实施例可以采用过滤网代替过滤器40使用，以降低洁净厌氧箱成本。
下面对本实施例的洁净厌氧箱的使用进行详细说明：
1、将待测试产品置于收容腔21内。
2、启动第一循环装置30，并同时往收容腔21注入惰性气体，第一循环装置30带动惰性气体在收容腔21内循环流动，以快速置换收容腔21内的原有气体，并在过滤装置的作用下，保持收容腔21内的洁净度，当惰性气体完全充盈收容腔21后，关闭第二进气口22和第二排气口23对应的单向阀门，从而使收容腔21保持为洁净度较高的厌氧环境。
3、启动第一循环装置70和加热装置，加热装置加热空气夹套11内的空气，第一循环装置70带动空气夹套11内空气夹套11内的空气循环流动，以空气夹套11内的空气温度的各向均匀性，从而能够对收容腔21的温度进行调整。其中，步骤2和步骤3可以同时进行。
4、当试验结束需要降温取出待测试产品时，打开第一进气口12和第一排气口13对应的单向阀门，并往空气夹套11注入大量低温空气或常温空气，以置换空气夹套11内的原有空气，同时启动第一循环装置70，以带动比预设温度的温度更低的空气或常温空气在空气夹套11内循环流动，提升置换速度，此时，套腔内的空气温度急剧下降，以间接降低收容腔21的温度，从而实现对收容腔21的降温操作；
5、当收容腔21内的温度降低至预设值时，打开舱门，取出待测试产品，完成试验。
结合图1-图6，本发明的外箱体10的内壁与内箱体20的外壁之间形成 空气夹套11，通过加热装置加热空气夹套11内的气体，以通过空气夹套11间接升高收容腔21的温度，当需要对降低收容腔21的温度时，对空气夹套11注入大量外部空气，以替换空气夹套11内温度较高的气体，从而通过空气夹套11间接对收容腔21进行降温，避免传统完全依赖氮气降温而因氮气能耗过大而造成使用成本过大，另外，通过空气夹套11间接提升收容腔21的温度，能够使收容腔21具有较佳的温度均匀性，从而保证洁净厌氧箱能够提供稳定的模拟试验环境。
以上所揭露的仅为本发明的优选实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明申请专利范围所作的等同变化，仍属本发明所涵盖的范围。
