请参照图1，本实施例提供的第一种抽真空装置100，其包括装置本体110、转轴130、真空泵转子146、电机定子160以及电机转子170。
其中，装置本体110上部为圆形结构，下部为方形结构，以便增大装置本体110下部的内部空间，从而提高装置本体110的储油量。装置本体110包括主体结构111、第一端盖112和第二端盖113。主体结构111内部设置有轴安装孔和出油出气通道124，出油出气通道124位于轴安装孔的上方。
第一端盖112通过螺栓安装于主体结构111的一端且两者共同围成真空泵仓140、储油腔120和连通腔122，真空泵仓140与出油出气通道124的一端连通，储油腔120与连通腔122相互连通。第一端盖112设置有进气孔114和排气孔116，进气孔114与真空泵仓140连通，排气孔116与连通腔122连 通。
为了防止进入真空泵腔的空气通过进气孔114回流到大气中，本实施例中，第一端盖112对应进气孔114的部位设置有单向阀115，从而使得气体由大气向泵体(真空泵仓140)内单向流动。
第二端盖113通过螺栓安装于主体结构111远离第一端盖112的一端，且第二端盖113与主体结构111共同围成电机仓150，电机仓150与出油出气通道124远离真空泵仓140的一端连通。
参照图4，转轴130转动连接于装置本体110内部且位于轴安装孔内。转轴130可以采用各种结构和形式，本实施例中，转轴130包括一体成型的电机轴132和真空泵轴134。
真空泵转子146固定安装于转轴130且位于真空泵仓140内，真空泵转子146与出油出气通道124远离电机仓150的一端对应。参照图5，真空泵转子146设置有多个滑槽和多个滑片148，多个滑片148分别滑动连接于多个滑槽内且能在离心力的作用下抵住真空泵腔的内壁(真空泵相关配套结构和具体工作原理为现有技术，在此不再赘述)。真空泵转子146、滑片148以及第一端盖112共同围成过渡油腔144和真空泵定子腔142。
过渡油腔144远离第一端盖112的一侧与储油腔120连通。与储油腔120连通的结构和形式有很多，本实施例中，转轴130设置有第一环形油道136、吸油孔137以及吸油通道138，第一环形油道136设置于转轴130的外壁，吸油通道138位于转轴130的内部且沿转轴130的轴线方向开设，储油腔120、第一环形油道136、吸油孔137、吸油通道138以及过渡油腔144依次连通，即储油腔120通过第一环形油道136、吸油孔137以及吸油通道138与过渡油腔144连通。真空泵定子腔142与过渡油腔144连通。同时真空泵定子腔142也与进气孔114连通。
本实施例中，吸油孔137沿转轴130的径向开设，可以贯穿转轴130，也 可以不贯穿转轴130。
为了方便储油腔120内的油能够通过第一环形油道136、吸油孔137、吸油通道138顺利进入过渡油腔144，本实施例中，装置本体110设置有吸油管139，吸油管139位于转轴130的下方。吸油管139一端与第一环形油道136连通，另一端与储油腔120连通且靠近装置本体110的底部。
电机定子160和电机转子170均位于电机仓150内，电机定子160固定连接于装置本体110，电机定子160连接有线束166，线束166从排气孔116伸出装置本体110，电机转子170与转轴130固定连接。电机定子160和电机转子170之间设置有间隙180，间隙180通过一贯穿电机定子160和装置本体110的通孔190与储油腔120连通，出油出气通道124通过上述间隙180与电机仓150连通。
电机定子160和电机转子170之间的连接可以采用各种结构形式，本实施例中，电机定子160位于电机转子170围成的区域内，即为外转子电机结构(电机其余配套结构和具体工作原理为现有技术，在此不再赘述)。
当然了，选用内转子电机结构也是可以的。
本实施例中的抽真空装置100的工作原理和过程是这样的：
工作时，电机转子170在电机定子160的驱动下转动，然后通过电机轴132、真空泵轴134的传动后，最终驱动真空泵转子146转动，在真空泵转子146的驱动下，进气孔114将气体吸入真空泵定子腔142内，同时储油腔120中的油液也会依次通过吸油管139、第一环形油道136、吸油孔137、吸油通道138吸入过渡油腔144内，位于过渡油腔144内的油液通过滑片148与真空泵仓140的间隙180与气体在真空泵定子腔142内混合，混合后的油气混合物会随真空泵转子146的转动在真空泵仓140内运动，并在到达预设(此时压缩达到最高压力值)位置时，通过出油出气通道124排出，经出油出气通道124排出的气体和油液，先是流入间隙180内与电机定子160和电机转子170的表 面接触从而实现对电机定子160和电机转子170进行冷却，之后会通过通孔190排至储油腔120中，在压力作用下，气体会在进入储油腔120后经连通腔122、排气孔116排出，而油液则会沉积在储油腔120，等待下一次被抽取使用。
综上，本实施例提供的抽真空装置100包括装置本体110、转轴130、真空泵转子146、电机定子160以及电机转子170，装置本体110设置有进气孔114、单向阀115、排气孔116、储油腔120以及电机仓150，储油腔120与排气孔116连通，转轴130转动连接于装置本体110，真空泵转子146固定安装于转轴130且与装置本体110内壁共同围成真空泵定子腔142，进气孔114和储油腔120分别与真空泵定子腔142连通，电机定子160和电机转子170均安装于电机仓150内，电机定子160固定连接于装置本体110，电机转子170与转轴130固定连接。
该抽真空装置100将现有的真空泵、油箱以及电机经过改装后巧妙地结合在一起，形成了一体化的抽真空结构，省去了原有的电机、真空泵等诸多零部件的物料和制作成本(现有技术中电机和真空泵共同具有四个端盖，本实施例提供的抽真空相当于省去两个端盖，剩余的两个端盖直接组成密封结构，该密封结构作为油箱直接使用)，且油箱由装置本体110直接构成而不再需要独立设置，不但从很大程度上降低了制造成本，而且优化了空间结构，缩小了整个装置的体积(或者总成长度)，有效弥补了现有的真空泵的缺陷。
请参考图2，上述提到的抽真空装置100为本实施例中的第一种形式，本实施例提供的抽真空装置100的第二种形式结合图2可知，主体结构111设置有连通孔201，连通孔201的一端与第一环形油道136连通，连通孔201的另一端与储油腔120连通。
可以理解的，该连通孔201的作用、效果、原理和吸油管139的相同，不同之处在于，通过在主体结构111上开孔，从而可以避免安装吸油管139，同 时，开孔时，根据所需的用油高度，可以对主体结构111进行倾斜开孔，选择一定的角度进行开孔，可以理解的，当孔是竖直开设时，其吸油高度较低，当孔水平开设时，其吸油高度较高，从而当孔开设在不同角度时，可以有效控制吸油高度。
实际上，一般水平和垂直不会选用，孔容易被堵死，一般高度太低，容易吸取杂质，高度太高，油量利用率较低，通常设计时根据实际需求对高度进行合理设计。结合图3，一般的，会选择一定的倾斜角度来开设连通孔201。
通过该方式，可以大大降低人工、材料等的费用，并且降低了工艺难度，制造更方便，有效节约成本。
同时，可选的，该抽真空装置100还包括挡板202，挡板202上设置有喷油孔203，挡板202通过螺钉安装在主体结构111的内部，其呈圆环片形，与主体结构111内部的一个端部连接，喷油孔203与出油出气通道124对应，可以在挡板202的不同位置开设喷油孔203，从而控制喷油的位置。
参照图6，本实施例提供的第二种抽真空装置100，其整体构造、工作原理以及取得的技术效果与第一种抽真空装置100基本相同，不同之处在于，本实施例中，电机定子160和电机转子170之间设置有环形的硅钢片164，出油出气通道124远离真空泵仓140的一端连通有第二环形油道126，第二环形油道126由装置本体110内壁、硅钢片164以及电机定子160围成。
参照图7，本实施例提供的第三种抽真空装置100，其整体构造、工作原理以及取得的技术效果与第二种抽真空装置100基本相同，不同之处在于电机转子170和电机定子160的具体结构。
本实施例中，电机转子170位于电机定子160围成的区域内，即为内转子 电机结构。同时，第二环形油道126由装置本体110内壁、硅钢片164以及电机转子170围成。
请参考图8，上述提到的抽真空装置100为本实施例中的第一种形式，本实施例提供的抽真空装置100的第二种形式结合图8可知：
可选的，主体结构111设置有连通孔201，连通孔201的一端与第一环形油道136连通，连通孔201的另一端与储油腔120连通。
可以理解的，该连通孔201的作用、效果、原理和吸油管139的相同，不同之处在于，通过在主体结构111上开孔，从而可以避免安装吸油管139，同时，开孔时，根据所需的用油高度，可以对主体结构111进行倾斜开孔，选择一定的角度进行开孔，可以理解的，当孔是竖直开设时，其吸油高度较低，当孔水平开设时，其吸油高度较高，从而当孔开设在不同角度时，可以有效控制吸油高度。
通过该方式，可以大大降低人工、材料等的费用，并且降低了工艺难度，制造更方便，有效节约成本。
同时，可选的，该抽真空装置100还包括挡板202，挡板202上设置有喷油孔203，挡板202通过螺钉安装在主体结构111的内部，其呈圆环形，与主体结构111内部的一个端部连接，喷油孔203与出油出气通道124对应，可以在挡板202的不同位置开设喷油孔203，从而控制喷油的位置。
参照图9-图12，本实施例提供的第四种抽真空装置100，其整体构造、工作原理以及取得的技术效果与上述的抽真空装置100基本相同，不同之处在于：

结合图9，可以理解的，外壳101与装置本体110形成的安装空间102位于整个结构的上方，结合图9，油仓105位于整个结构的下方，并且两者连通。
结合图9，电机控制器的电器元件103包括电路板、高度相对较高的电容、大功率三极管、集成电路、消音器等，这些结构一般是直流电机、泵排气噪音控制等必需的结构，将这些结构安放在安装空间102内，大大提高了空间利用率。
外壳101还连接有电器仓盖107，两者可以转动连接、滑动连接、可拆卸的连接等，通过这种方式，可以很方便的打开安装空间102，从而取下或安装相关部件。
外壳101的底部设置有总成安装孔106，从而可以更加方便的将整个结构安装在外部的其他结构上。
结合图9、图10和图12，通过油仓105与储油腔120连通，可以大大增大储油量，外壳101的底部还可以设置成中空的结构，从而进一步增大储油量。
结合图11，通过安装散热片108，可以有效提高散热效果。
并且，上述的相关部件的安装有效提高了抽真空装置100的空间利用率，使得整个结构一体化程度较高，合理性更好，实用性强。
可以理解的，上述提到的抽真空装置100将真空泵、油箱和电机进行集成，成为一个整体，可以一体成型进行制造，可以理解的，电机部分呈圆柱状，其可以通过法兰、紧固件等安装到对应的端盖上，然后端盖再通过紧固件将整个装置安装到外壳101上，从而可以成为一个稳定的结构。
本实施例还提供了一种真空设备，其包括上述的抽真空装置100，从而可以有效优化自身结构，缩小自身体积，从而降低制造成本，弥补现有的真空设备的缺陷。
