本发明实施例提供的便捷式抽真空装置10，通过在所述壳体11内设置电池，利用所述电池对所述抽真空装置进行供电，从而适用于停电或者是在户外没有外接电源的场合，大大地提高了抽真空装置的适用性。同时，通过将所述微型真空泵12、电路板13以及所述电池均安装于所述壳体11内，因此，使得整个抽真空装置结构更为紧凑且体积小，有利于提高用户的携带便捷性。此外，利用在所述壳体11上设置所述第一抽气口111可连接至容器内，从而使得所述便捷式抽真空装置10能够与容器配套使用，大大地满足了用户的不同使用需求。
请一并参阅图1、图3至图7，为本发明实施例提供的一种抽真空储存装置100，包括容器20以及如上述的便捷式抽真空装置10，所述便捷式抽真空装置10可拆卸连接于所述容器20。所述便捷式抽真空装置10用以对所述容器20进行抽真空，以保持所述容器20内食物的新鲜度。
优选地，所述便捷式抽真空装置10可通过螺纹连接或者是卡扣连接的方式与所述容器20连接。
所述容器20上开设有连通至上述第一抽气口111的第二抽气口21，以便于气体能够经由所述第二抽气口21向所述第一抽气口111出气。在本实施例中， 所述便捷式抽真空装置10上的连接凸台112a的一端伸入所述第二抽气口21内。所述容器20的容量小于或者等于1.5L，以便于用户携带的同时，也能够防止所述容器20的容量过大而增加了所述便携式抽真空装置10对所述容器20进行抽真空的时间。即，当所述容器20的容量小于或者等于1.5L时，在所述电机122的功率为2W～40W的情况下，利用所述便携式抽真空装置10对所述容器20进行抽真空时，其抽真空的时间为10s～50s，从而实现快速抽真空，节省用户的使用时间。因此，利用所述便捷式抽真空装置10对所述容器20进行抽真空时，若所述电机122的功率不变，始终采用2W～40W，则当所述容器20的容量变小时，其抽真空的时间相应减少，例如，当所述电机122的功率为40w时，所述容器20的容量为100ml～500ml时，抽真空的时间可为10s～20s之间。因此，用户可根据自己的实际情况选用不同容量的容器。
可以理解的是，所述容器20的容量也可大于1.5L，但此时，采用上述便携式抽真空装置10对该容器进行抽真空时，其抽真空的时间则会相应的增加。
所述容器20可为杯子，包括具有开口(未标示)的杯体22、设于所述杯体22周缘的密封圈23以及杯盖24，所述杯盖24封闭所述开口并压紧所述密封圈23，所述杯盖24上开设有所述第二抽气口21，并且所述第二抽气口21连通至所述杯体22内。利用所述密封圈23的密封作用，可防止外界的气体从所述杯盖24与所述杯体22的连接处进入，确保所述杯体22内的真空状态。优选地，所述杯体22内可用以盛放食物，例如新鲜的水果、果汁或汤水等。由于所述杯盖24与所述杯体22的密封作用，当采用所述抽真空装置对所述杯体22进行抽真空后，可将所述抽真空装置与所述杯体22及杯盖24分离，此时，可将整个容器20当成旅行杯携带外出，方便快捷。
进一步地，为了进一步确保所述杯体22与所述杯盖24的密封性，所述密封圈23可为两根，所述杯盖24的横截面形状为阶梯型，包括平行设置的第一阶梯面(未标示)以及第二阶梯面(未标示)，所述杯体22的周缘上延伸有一圈台阶(未标示)，其中一根所述密封圈23挤压于所述台阶221与所述第一阶梯面之间，另外一根所述密封圈23挤压于所述杯体22的上端面与所述第二阶梯面之间，以防止外界气体经由所述杯体22与所述杯盖24之间的连接处进入，确保所述杯体22的密封效果，进而有利于确保后续的抽真空效果。
优选地，所述杯盖24可通过螺纹连接的方式与所述杯体22连接，例如， 在所述杯盖24以及杯体22上对应设置螺纹。同理，也可在所述杯盖24上设置卡扣或扣槽，然后对应在所述杯体22上设置扣槽或卡扣，同时在所述杯盖24及杯体22上对应设置螺纹，通过所述杯盖24与所述杯体22的螺纹配合来使得所述杯盖24上的卡扣或扣槽与所述杯体22上的扣槽或卡扣扣合，以达到所述杯盖24与所述杯体22连接的目的。采用上述方式，可方便所述杯盖24与所述杯体22的连接以及分离，从而便于存放食物或者是对所述杯体22及杯盖24进行清洗。
进一步地，为了便于用户使用，当将所述便携式抽真空装置10与所述容器20连接时，所述连接凸台112a与所述杯盖24上的第二抽气口21连接，即，所述连接凸台112a外周上的密封件压紧于所述连接凸台112a以及所述第二抽气口21之间。此外，为了进一步确保密封效果，所述密封件外周上设置有螺纹，所述连接凸台112a可通过螺纹旋紧于所述第二抽气口21，从而确保密封效果的同时，也无需在所述连接凸台112a上额外设置螺纹。
进一步地，为了便于用户使用，在本实施例中，所述杯盖24可包括上杯盖242及下杯盖241，所述下杯盖241与所述杯体22连接，所述上杯盖242与所述下杯盖241螺纹连接或者卡扣连接，所述第二充气口21经由所述上杯盖242贯通至所述下杯盖241。采用将所述杯盖24分成上杯盖242及下杯盖241的方式，当用户使用该容器喝果汁或者汤水时，只需打开所述上杯盖242，此时，所述下杯盖241依然与所述杯体22连接，用户可通过所述第二充气口21将果汁或者汤水倒出、或者是可通过在所述第二充气口21导入吸管，方便用户食用，无需将整个杯盖打开，同时也可减少食物与空气的接触面积，保持食物食用口感的新鲜度。
进一步地，所述容器20可为搅拌容器，即，所述容器20内设置有搅拌刀片，此时，可将所述杯体22与搅拌机座配合使用，则可将所述容器20内存放的食物进行搅拌。优选地，在对所述容器20内的食物进行搅拌之前，可采用所述抽真空装置将所述容器20内的空气抽取到容器20外，从而使得食物在搅拌之前不易被空气氧化，进而有利于保持食物的新鲜口感。
此外，在其他实施例中，当所述容器20为杯子时，所述杯体22还可为双开口杯，即，所述杯体22的两端均开设有开口，所述杯盖24封闭所述杯体22的一端开口，所述杯体22的另一端开口用以连接至料理机，即，可将所述杯体 22的另一端连接至榨汁机的杯子、或者是搅拌器的杯子，对榨汁机的杯子或者是搅拌器的杯子内部进行抽真空后，再对食物进行榨汁或搅拌，从而保持食物的新鲜口感。
此外，为了便于保存携带，所述容器20还可为袋子，例如，具有封口的塑胶袋子或者是敞口的塑料袋。当将所述便携式抽真空装置10用以对袋子或者塑料袋进行抽真空时，可在所述连接凸台112a上连接一些连接管，以便于抽气，采用袋子的做法，使得所述便捷式抽真空装置10能够与不同类型的容器20进行配合使用，从而使得所述便捷式抽真空装置10的适用范围更广，更有利于用户选择使用。
在本实施例中，所述抽真空储存装置100还包括单向阀30，所述单向阀30设于所述第二抽气口21上，用以控制所述第二抽气口21与上述壳体11的连通或闭合。由于所述单向阀30的设置，使得气流自所述杯体22内向外侧出气，不允许对杯体22内进气，从而能够保持杯体22内的真空状态。
所述第二抽气口21的横截面形状为阶梯形，包括水平抵接部211以及与所述水平抵接部211垂直设置的竖直抵接部212，所述单向阀30包括阀体31以及分别延伸于所述阀体31相对两端的第一延伸部32和第二延伸部33，所述第一延伸部32抵接于所述水平抵接部211，所述第二延伸部33抵接于所述竖直抵接部212。在本实施例中，所述单向阀30的阀体31设于所述第二抽气口21内，所述第一延伸部32和第二延伸部33均为延伸于所述阀体31两端的薄板。利用所述第一延伸部32与所述第二延伸部33分别于所述第二抽气口21的水平抵接部211及竖直抵接部212抵接，从而能够将所述单向阀30牢牢地固定在所述第二抽气口21处。可以理解的是，在其他实施例中，所述第二抽气口21还可为圆形孔、U形孔等。
在本实施例中，所述单向阀30采用硅胶材质制成，当所述便携式抽真空装置10抽真空完成时，所述单向阀30受压变形，以使所述第一抽气口111与所述第二抽气口21实现密封。具体地，在所述阀体31上开设有至少一个通气孔311，当所述便携式抽真空装置10与所述容器20连接时，所述阀体31的外壁与所述第二抽气口21的内壁之间具有间隙312，此时，所述至少一个通气孔311与所述间隙连通，所述容器20内的气体经由所述间隙至所述至少一个通气孔311向所述第一抽气口21进气，从而实现通过所述单向阀30连通所述第二抽气口 21与所述第一抽气口111，进而便于抽真空工作的进行。(如图6所示)
如图7所示，当所述便携式抽真空装置10抽真空完成时，由于所述阀体31为硅胶材质，因此容易受压变形，使得所述阀体31的外壁受压紧贴于所述第二抽气口21的内壁，即，所述阀体31的外壁与所述第二抽气口21的内壁之间不再有所述间隙312，因此，气体无法经由所述间隙312至所述通气孔311进气，则此时，所述容器20内的气体停止向所述至少一个通气孔311进气，从而确保所述容器20内始终保持抽真空后的负压值，进而确保所述容器20内部没有外界空气进入，确保食物保持新鲜口感。
进一步地，为了方便用户在抽真空后打开所述杯盖24，所述单向阀30上还设置有排压结构34，用以将所述杯体22内的压力排出，以便于用户打开杯盖24。优选地，所述排压结构34为可提拉设于所述单向阀30上的凸起，当用户需要打开所述杯盖24时，只需先将所述排压结构34提起，此时，所述单向阀30受压变形，所述阀体31的外壁与所述第二抽气口21的内壁之间具有所述间隙312，气压从所述间隙312处向所述至少一个通气孔311排出，即可实现便捷的打开所述杯盖24，为客户使用提供了便利。
进一步地，当将所述杯体22与搅拌机或者榨汁机配合使用时，为了避免搅拌过程中的食物碎屑、泡沫等挡在所述单向阀30的阀腔外部而造成所述第二抽气口21堵塞的情况，可在所述杯盖24邻近所述单向阀30的位置处设置挡片，利用所述挡片阻挡搅拌过程中产生的食物碎屑或泡沫等，从而防止所述单向阀30的阀腔被堵塞，同时也便于后续清洗。优选地，所述挡片可为设于所述杯盖24外周缘上的环形片状结构，以防止所述挡片遮挡所述杯盖24上的第二抽气口21。
操作时，按下所述控制开关115，所述微型真空泵12开始工作，经由所述抽气嘴121a对所述容器20内部进行抽气，当所述容器20内的压值达到预设的负压值(-50～-90)kpa时，再次按压所述控制开关115，所述微型真空泵12停止工作，所述指示装置发出提醒指示；此时，可将所述便捷式抽真空装置10与所述容器20分离，所述容器20在所述单向阀30的作用下，仍处于上述的压值下，即，所述容器20内部处于真空状态，因此，能够使得盛放在所述容器20内的食物保持新鲜的口感。
采用将所述便捷式抽真空装置10与所述容器20配合使用，从而能够对容 器20进行抽真空，方便食物的保存，确保食物的新鲜口感。此外，由于所述容器20与所述便捷式抽真空装置10为可拆卸连接，因此，当抽真空完成后，可将容器20与便捷式抽真空装置10分离，因而在外出携带时，二者可分开携带，减少整个抽真空储存装置100装配在一起的占用空间，进而方便用户携带。
