具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
应当理解的是，本发明中采用术语“前”、“后”等来描述各种信息，但这些信息不应限于这些术语，这些术语仅用来将同一类型的信息彼此区别开。例如，在不脱离本发明范围的情况下“前”信息也可以被称为“后”信息，“后”信息也可以被称为“前”信息。
如图2和图3所示，本发明提供了一种多功能真空包装机，其包括包装机本体以及设于包装机本体上的真空泵组3、发热系统4和控制 系统6，包装机本体具有用于容纳真空包装袋的真空腔，具体而言，包装机本体包括铰接连接的底座1和顶盖2，底座1的顶面成型有向下凹陷的下腔室11，顶盖2用于开闭下腔室11，顶盖2的底面成型有向上凹陷的上腔室21，上腔室21与下腔室11在顶盖2闭合下腔室11时形成该真空腔，真空泵组3设于底座1上并与下腔室11相连通，用于对真空腔内的气体进行抽吸，发热器系统4用于热封真空包装袋，其包括设于底座1顶面的发热器41与设于顶盖底面的压条42，发热器41设于下腔室11外，压条设于上腔室21外，控制系统6设于底座1上并真空泵组3和发热器41电连接，用于控制真空泵组3和发热器41的开启与关闭。
基于上述结构，该多功能真空包装机可同时完成内抽与外抽操作，内抽时将真空包装袋放入下腔室11内，调整真空包装袋使真空包装袋的袋口靠近发热器41并位于下腔室11外，按压顶盖2关闭下腔室11，压条42随着顶盖2的转动接触发热器41并与发热器41一同固定真空包装袋，启动真空泵组3，下腔室11内的气体在真空泵组3的抽吸下逐渐减少，下腔室11的真空度不断提高，下腔室11内的真空度到达指定标准，关闭真空泵组3，启动发热系统4，发热器41发热烧灼真空包装袋，真空包装袋完成热封，随后打开顶盖2使空气进入下腔室11，真空包装袋在袋内外之间压力差的作用下发生皱缩，完成内抽操作；外抽时需要准备特制的外抽包装袋，设置外抽包装袋使其整体位于下腔室11外，外抽包装袋的袋口位于下腔室11内并靠近发热器41，按压顶盖2关闭下腔室11，压条42随着顶盖2的转动接触发热器41并与发热器一同固定外抽包装袋，启动真空泵组3，外抽包装袋内的气体被抽出，外抽包装袋内的压力不断下降，外抽包装袋在袋内外之间压力差的作用下发生皱缩，外抽包装袋的皱缩到达一定程度关闭真空泵组3，启动发热器41热封真空包装袋，完成真空包装袋的外抽操作。如此，发热系统4的发热器41和压条42设于真空腔外不再占用真空腔的空间，消除了以往情况下无法发挥作用的多余空间，在保证抽吸 效果的同时减小了真空腔的容积，真空腔容积的减小也也降低了对真空泵组3的功率要求，成本也容易得到控制，同时发热器41和压条42与真空包装机的边缘距离得到缩减，更易实现真空包装袋的外抽操作，也即该多功能真空包装机能够同时实现内抽与外抽，其实用性得到极大的提升，该多功能真空包装机制作成本低，可同时实现内抽与外抽，使用方便，易于推广。
需要注意的是，发热器41与压条42的设置位置也可以进行调整，如将发热器41设于顶盖2上，此时，与发热器41相匹配的压条42设于底座1上，这种发热器41与压条42的位置调整所带来的技术效果是一致的。
进一步的，在本申请的一些实施例中，真空泵组3和控制系统6设于底座1上并位于下腔室11的旁侧，真空泵组3和控制系统6的位置调整降低了底座的高度，进一步提升了外抽时的舒适度，有利于外抽操作的实施，提升了用户的使用体验。
可选的，在本申请的一些实施例中，真空腔的腔壁上设有抽气口5，真空泵组3通过抽气口5与真空腔相连通，在本发明实施例中，抽气口5设于下腔室11的侧壁上，真空泵组3通过抽气口5与下腔室11相连通，从而完成对真空腔内气体的抽吸，当然，抽气口5也可以设置在上腔室21的侧壁上，此时真空泵组3则与上腔室21相连通，这种抽气口5位置的变化所带来的技术效果是一致的。
进一步的，本申请的一些实施例中，底座1的顶面设有夹袋器7，夹袋器7与发热器41位于下腔室11的同一侧。发热器41旁侧设置的夹袋器7能够在抽吸过程中夹紧真空包装袋的袋口，防止真空包装袋在抽气与热封的过程中发生跑动，影响抽吸的正常进行，保证抽吸过程的稳定，具体而言，内抽时夹袋器7升起并夹紧真空包装袋的袋口，外抽时夹袋器7沉入底座1内，避免顶靠真空包装袋影响外抽的正常进行。
可选的，本申请的一些实施例中，底座1和顶盖2的铰接处位于 底座1远离发热器41的一侧，如此，发热器41与夹袋器7更为靠近操作人员，使用起来十分的方便。
进一步的，在发明实施例中，包装机本体的真空腔由底座1上的下腔室11和顶盖2上的上腔室21组合形成，下腔室11的腔壁以及上腔室21的腔壁采用PP材料、PC材料或尼龙材料制成，上述材料易于获取，能够根据需求制作通过注塑形成各种合金材料不易达到的异形结构。实际制作时，操作人员可根据真空包装机的承压需求选择其中一种或多种材料使用。需要注意的是，对于底座1和顶盖2上的其他区域而言，由于其不存在承压需求，因此可以选择其他种类的塑料材料以降低真空包装机的生产成本。
另外，需要注意的是，对于真空包装机的顶盖2而言，其也可以采用其他易于注塑成型的材料如尼龙材料或玻璃材料等制成，具体而言，顶盖2使用透明的玻璃材料制成，此时顶盖2不设上腔室21，但是可以通过透明的顶盖2更加直观的了解下腔室11内的具体抽吸情况。
综上所述，本发明提供了一种多功能真空包装机，其包括铰接连接的底座和顶盖，底座的顶面成型有下腔室，顶盖的底面成型有上腔室，底座上设有发热系统、真空泵组和控制系统，发热系统包括发热器和压条，发热器设于底座上并位于下腔室外，压条设于顶盖上上并位于上腔室外，真空泵组通过设于下腔室腔壁的抽气口与下腔室相连通，控制系统用于控制发热器和真空泵组完成热封与抽吸操作。与现有技术相比，该多功能真空包装机优化了发热系统的设置位置，减小了真空腔的容积，降低了真空泵组的功率要求，有利于控制制作成本，该多功能真空包装机可同时实现内抽与外抽，实用性高，使用方便，易于推广。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本发明的保护范围。
