背景技术

在其中一个实施例中，所述均压阀包括复位件以及推拉件；
所述推拉件包括相互连接的封堵部以及推拉部，所述推拉部位于所述均压口外，所述复位件将所述封堵部抵压在所述均压口上，推动或拉动所述推拉部带动所述封堵部避让所述均压口从而使所述均压口内外连通。
本申请还提供一种抽真空杯，所述抽真空杯包括杯体以及如上述抽真空杯盖，所述杯体开设有上杯口，所述上杯口与所述抽真空杯盖的所述连接部密闭连接。
本申请还提供一种抽真空搅拌/粉碎杯，所述抽真空搅拌/粉碎杯包括杯体以及上述的抽真空杯盖，
所述杯体开设有上杯口，所述上杯口与所述抽真空杯盖的所述连接部密闭连接；
所述杯体内设有搅拌/粉碎装置。
上述抽真空杯盖，上盖组件与下盖组件之间具有容积可变的抽真空腔。在使用抽真空杯盖对与其密闭连接的容器进行抽真空时，由于抽真空腔容积可变为零，抽真空腔内的空气可完全被排出抽真空腔，提高了抽真空杯盖的抽气效率。
在其中一个实施例中，上述抽真空杯，按压上盖组件至最低点使抽真空腔的容积变到最小时，上盖组件能够压紧下盖组件吸气孔上的吸气单向阀，通过锁紧结构将上盖组件和下盖组件锁紧，将上盖组件保持在压紧下盖组件吸气孔上的吸气单向阀的状态，确保了即使抽真空杯在倒置放置运输时，由于上盖组件始终给吸气单向阀提供压力，即使杯体内的液体在重力和冲击力作用下，吸气孔上的吸气单向阀也不会被打开，实现了对下盖组件上的吸气孔进行有效密封，从而保证了杯体内所需的真空度的目的。克服了现有的抽真空杯，抽真空杯在倒置放置运输时，杯体内的液体容易在重力和冲击力作用下打开吸气孔上的阀体，渗漏到抽真空杯盖部分，进而影响杯体内真空度的缺陷。产生了抽真空杯被倒置放置运输时能够有效地防止杯体内的液体向抽真空杯盖内渗漏进而保证容器内所需真空度的有益效果。

上述抽真空杯，具有抽真空杯盖100，能够对容器进行高效率地抽气，使容器内的空气减少或完全排出，从而可以延长容器内食品的保质期。
可选地，上杯口210设有外螺纹，连接部123设有内螺纹，上杯口210与连接部123通过螺纹密闭连接。

请继续参阅图3至图5所示，本申请提供的一实施例的抽真空杯盖100包括上盖组件110以及下盖组件120，下盖组件120设有与容器口部密闭连接的连接部123，上盖组件110 与下盖组件120之间具有容积可变的抽真空腔，抽真空腔的容积可变为零。其中，抽真空腔设有吸气孔，吸气孔用于抽真空腔从与抽真空杯盖100密闭连接的容器内吸入空气。抽真空腔设有排气孔，排气孔用于从抽真空腔排出空气。
上述抽真空杯盖100，上盖组件110与下盖组件120之间具有容积可变的抽真空腔。在使用抽真空杯盖100对与其密闭连接的容器进行抽真空时，由于抽真空腔容积可变为零，抽真空腔内的空气可完全被排出抽真空腔，提高了抽真空杯盖100的抽气效率。
作为一种可选实施方式，抽真空杯盖100包括活塞130以和活塞筒140，通过使活塞130与活塞筒140的相对移动形成容积可变的抽真空腔。
在本实施例中，活塞130与上盖组件110连接，活塞筒140与下盖组件120连接，活塞130能够在活塞筒140内密封地移动以在活塞130与活塞筒140之间形成抽真空腔。当活塞130在活塞筒140内移动至最底点时，活塞130的底壁与活塞筒140的底壁贴合，抽真空腔容积变为零。
利用抽真空杯盖100对容器进行抽真空时，将活塞130在活塞筒140内移动至最底点时，从而使活塞130的底壁与活塞筒140的底壁贴合，活塞130与活塞筒140形成的抽真空腔容积变为零，其内暂存的空气被完全排出抽真空腔，当活塞130移动使抽真空腔容积增大时，能够从容器内吸取更多的空气，从而提高抽真空的效率。
在其他实施例中，可以是活塞130与下盖组件120连接，活塞筒140与上盖组件110连接，活塞130能够在活塞筒140内密封地移动以在活塞130与活塞筒140之间形成抽真空腔。当活塞筒140在活塞130外移动至最底点时，活塞130的顶壁与活塞筒140的顶壁贴合，抽真空腔容积变为零。利用该抽真空杯盖100对容器进行抽真空时，将活塞筒140在活塞130外移动至最底点时，从而使活塞130的顶壁与活塞筒140的顶壁贴合，活塞130与活塞筒140形成的抽真空腔容积变为零，其内暂存的空气被完全排出抽真空腔，当活塞130移动使抽真空腔容积增大时，能够从容器内吸取更多的空气，从而提高抽真空的效率。
进一步可选地，抽真空杯盖100设有弹性件150，弹性件150的两端分别与上盖组件110以及下盖组件120抵接且弹性件150位于抽真空腔外。
弹性件150的两端分别与上盖组件110以及下盖组件120连接，当将活塞130移动至活塞筒140内的最低点时，弹性件150处于压缩状态，利用该弹性件150的弹力能够将活塞130弹起从而对容器实现抽真空，节省了利用活塞130抽气的人力。同时，由于弹性件150设置在抽真空腔外，不占用抽真空腔内的空间，不会影响活塞130与活塞筒140相对的移动，从而活塞130的底壁与活塞筒140的底壁贴合，能够使抽真空腔容积变为零，提高抽气效率。
可选地，弹性件150可以是螺旋弹簧，该螺旋弹簧套在活塞筒140外侧。螺旋弹簧能够提供均衡的弹性力，使活塞130能够被平衡地弹起。
进一步地，螺旋弹簧与活塞筒140外壁之间具有一定的距离，以避免压缩弹簧或弹簧弹起时与活塞筒140外壁产生摩擦。
作为一种可选实施方式，上盖组件110包括上盖板111以及沿上盖板111设置的向下盖组件120方向延伸的上外周壁112，下盖组件120包括下盖板121以及沿下盖板121设 置的向上盖组件110方向延伸的下外周壁122。弹性件150位于活塞130与上外周壁112之间且位于活塞筒140与下外周壁122之间。当活塞130在活塞筒140内移动至最底点时，上外周壁112套设在下外周壁122或下外周壁122套设在上外周壁112。
通过设置上外周壁112以及下外周壁122，能够将弹性件150与外部环境隔开，起到保护弹性件150的作用。进一步地，上外周壁112以及下外周壁122还能避免操作抽真空杯盖100时被弹性件150夹伤。
请继续参阅图4至图5所示，当活塞130在活塞筒140内移动时，上外周壁112位于下外周壁122与弹性件150之间。下外周壁122不受上外周壁112的影响，可以通过旋转下外周壁122方便地使抽真空杯盖100与上杯口210螺纹连接。
进一步地，上盖板111设有凸出于上外周壁112的凸缘，当按压上盖组件110将活塞130移动至最低点时，凸缘遮挡住下外周壁122与上外周壁112之间的缝隙，一方面可以避免夹伤，另一方面也可以是抽真空杯盖100美观。
在其他实施例中，也可以是当活塞130在活塞筒140内移动时，下外周壁122位于下上周壁与弹性件150之间，从而上盖左键包围在下盖组件120上，避免按压上盖组件110时手被上盖组件110与下盖组件120之间的缝隙夹伤。
作为一种可选实施方式，吸气孔开设于活塞筒140的底壁上，吸气孔设有吸气单向阀143，吸气单向阀143只允许空气由容器进入抽真空腔内。活塞130为中空结构，活塞130与上盖组件110连接处具有排气槽133，排气孔开设于活塞130的底壁上，排气孔设有排气单向阀135，排气单向阀135只允许空气从抽真空腔排出。
通过在吸气孔设置吸气单向阀143以及在排气孔设置排气单向阀135，能够有利于空气在抽真空腔内的定向流动，对空气的单向密封性能更为可靠。
可选地，活塞130的底壁设有排气阀座134，排气单向阀135设置在排气阀座134上。
可选地，活塞130的外壁底端设有密封限位筋138，密封限位筋138为双环形的凸出筋条，该双环形的凸出筋条之间固定有活塞密封圈139。当活塞130在活塞筒140内移动时，活塞密封圈139使活塞130与活塞筒140内壁之间密封，实现活塞130在活塞筒140内的密封移动。
请继续参阅图3所示，在本实施例中，活塞130顶部设有若干排气槽133，活塞130与上盖组件110的上盖板111连接时，排气槽133使活塞130的中空结构与外界连通，用于当压缩活塞130时，将通过排气孔进入活塞130中空结构的空气排出活塞130，进一步地将空气排出抽真空杯盖100外。
可选地，活塞130顶部可以直接与上盖板111连接，也可以是活塞130与上盖板111为一体结构。
又可选地，排气槽133内设有活塞安装柱131，活塞安装柱131内可以设有螺纹孔，上盖板111通过活塞连接件132与活塞安装柱131连接，从而将活塞130固定在上盖板111上。其中，活塞连接件132可以是螺钉。这种连接方式可以是活塞130与上盖板111之间的连接更加坚固，并且通过分别制造活塞130、上盖板111，后期再将活塞130、上盖板111连接在一起，相对于活塞130与上盖板111一体结构的方案降低了制造难度。
进一步地，上盖组件110还包括装饰盖板113，装饰盖板113盖设在上盖板111上，以遮挡上盖板111上漏出的活塞连接件132，增加抽真空杯盖100的美观。
可选地，抽真空杯该的连接部123为沿下盖板121设置的、与下外周壁122延伸方向相反的外周壁，该外周壁内设有内螺纹与容器连接。
可选地，连接部123内设有连接密封圈124，连接密封圈124设置在连接部123内螺纹顶端，以提高上杯口210与连接部123连接时的密封性能，确保抽真空后容器的密封性，进一步延长容器内食品的保质期。
可选地，下盖组件120设有活塞筒支座141，活塞筒支座141可以设有内螺纹，活塞筒140可以设有外螺纹，从而活塞筒支座141与活塞筒140螺纹连接，从而将活塞筒140固定在下盖板121组件上，在活塞筒支座141与活塞筒140之间形成供活塞130在其内移动的活塞腔。进一步地，吸气孔开设在活塞筒支架上，在该吸气孔上设有第一吸气阀座142，吸气单向阀143安装在第一吸气阀座142上。
在本实施例中，活塞筒支座141与下盖板121分别制造后组装而成。进一步地，活塞筒支座141与下盖板121之间可以设有支座密封圈145。
在其他实施例中，活塞筒支座141与下盖组件120的下盖板121可以是一体结构，
在其他实施例中，也可以是活塞筒140与下盖板121为一体结构。在活塞筒140的底部连接有活塞筒支座141，在活塞筒支座141上设有第一吸气阀座142以及吸气单向阀143。
作为一种可选实施方式，下盖组件120还设有过滤网144，过滤网144罩设在吸气孔下部，也就是吸气单向阀143下方。通过设置过滤网144能够防止在抽真空过程中，容器内的食品被吸入抽真空腔内。
作为一种可选实施方式，活塞130上设有第一导向结构136，活塞筒140内设有与第一导向结构136匹配的第二导向结构146，第一导向结构136与第二导向结构146配合使活塞130在活塞筒140内定向移动。
可选地，请参阅图3所示，第一导向结构136可以是活塞130外壁上设置的导向筋，第二导向结构146可以是活塞筒140内壁上设置的导向槽。在本实施例中，导向筋沿活塞130外壁纵向设置，导向槽仅设置在活塞筒140内壁的上端。当活塞130在活塞筒140内纵向移动时，导向筋位于导向槽内并受到导向槽的限制，从而能够使活塞130在活塞筒140内的纵向相对移动更为平稳。
在其他实施例中，第一导向结构136以及第二导向结构146可以是其他结构形式。例如，第一导向结构136是活塞130外壁上设置的导向槽，第二导向结构146是活塞筒140内壁设置的导向筋。
需要说明的是，至少第一导向结构136或至少第二导向结构146的长度与活塞130相对活塞筒140的移动路径长度相当，以使活塞130相对活塞筒140的移动路径上均能够得到第一导向结构136与第二导向结构146的导向作用。
当第一导向结构136的长度与活塞130相对活塞筒140的移动路径长度相当时，第二导向结构146可以仅设置在活塞筒140内壁顶端。同理，当第二导向结构146的长度与活塞130相对活塞筒140的移动路径长度相当时，第一导向结构136可以仅设置在活塞130 外壁的底端。当然，也可以是第一导向结构136的长度以及第二导向结构146的长度均与活塞130相对活塞筒140的移动路径长度相当。
进一步地，作为一种可选实施方式，上盖组件110和/或活塞130设有第一锁定结构137，下盖组件120和/或活塞筒140设有与第一锁定结构137匹配的第二锁定结构147，当活塞130在活塞筒140内移动至最底点时，第一锁定结构137能够与第二锁定结构147锁定。
当利用抽真空杯盖100对容器抽真空后或不使用抽真空杯盖100时，可以通过第一锁定结构137与第二锁定结构147能够将活塞130锁定在最低点位置，节约贮存空间。
可选地，请参阅图3所示，第一锁定结构137可以是设置在活塞130上的导向筋顶端，第二锁定结构147可以是设置在活塞筒140内壁顶端的导向槽两侧的凸缘结构。当活塞130在活塞筒140内移动至最底点时，导向筋顶端从导向槽中脱离，旋转活塞130使导向筋顶端抵接在凸缘结构下，从而使活塞130锁定在最低点位置。
在该实施例中，第一锁定结构137与第一导向结构136、第二锁定结构147与第二导向结构146整合为一体的设置方式，能够简化活塞130、活塞筒140的结构，降低制造难度以及制造成本。
进一步地，在该实施例中，第一锁定结构137与第二锁定结构147设置在抽真空杯盖100内部，使抽真空杯盖100外观简洁。
进一步地，第二锁定结构147可以是围设在活塞筒140内壁顶端的凸缘结构，凸缘结构部分设有若干缺口作为导向槽。设置若干缺口作为导向槽，锁定或解锁时仅需将活塞130旋转较小的角度即能够实现，能够提高活塞130锁定以及活塞130解锁的便利性。
在其他实施例中，第一锁定结构137以及第二锁定结构147也可以是其他相互锁定的形式。例如，第一锁定结构137、第二锁定结构147分别为设置在上盖组件110的弹性卡扣、设置在下盖组件120的卡槽。当活塞在活塞筒140内移动至最底点时，弹性卡扣能够扣合在卡槽中，实现上盖组件110与下盖组件120的锁定，从而使活塞130锁定在最低点位置，节省贮存空间。
作为一种可选实施方式，抽真空杯盖100上开设有均压口125，均压口125连通容器与外界大气，均压口125设有均压阀160。当需要打开抽真空杯盖100时，可打开均压阀160，使容器内外的压力均衡，方便打开抽真空杯盖100。
可选地，请参阅图6所示，均压阀160包括弹性推拉件161。弹性推拉件161包括相互连接的弹性封堵部以及推拉部，弹性封堵部封堵在均压口125上，推拉部位于均压口125外，推动或拉动所述推拉部能够使所述弹性封堵部产生形变从而使均压口125内外连通。本实施例的均压阀160利用弹性推拉件161自身的弹性产生形变，从而使均压口125内外接通；同时利用弹性推拉件161自身的弹性复位，恢复至弹性封堵部封堵均压口125。本实施例的弹性推拉件可根据均压口125的位置以及设计需要设置成推动弹性推拉件161打开均压口125或拉伸弹性推拉件161打开均压口125的结构。
请继续参阅图6所示，本实施例的弹性推垃件161的弹性封堵部为弹性推拉件上的凸起结构，该凸起结构的依靠弹性推拉件自身的弹性抵压在均压口125上，当推动位于均压 口外的推拉部时，使该凸起解脱远离均压口125从而使均压口内外连通，进而使杯盖内外压力相同，便于打开杯盖。
请继续参阅图7，本申请还提供另一种实施方式的均压阀160。均压阀160包括复位件162和推拉件163。推拉件163包括相互连接的封堵部1631以及推拉部1632，推拉部1632贯穿均压口125并且推拉部部分位于均压口125外，复位件162将封堵部1631抵压在均压口125上，推动或拉动推拉部带动封堵部1631避让均压口125从而使均压口125内外连通。
可选地，请继续参阅图7所示，均压阀160还包括均压密封圈164，均压密封圈164套在推拉件上并抵接在均压口125上，以确保均压阀160密封均压口时的密封性。
可选地，推拉件163还包括限位部1633，当按压或拉动推拉件163至能够使均压口125内外连通位置时，推拉件163的限位部1633抵受到杯盖的限制不可继续移动，从而能够避免推拉件163从均压口脱离。
又可选地，推拉件163还包括导向部，进而杯盖上可设有导向配合部1634，在本实施例汇总，导向部为凹槽，导向配合部1634未设置在杯盖上的凸筋，凹槽沿受凸筋限制定向移动，使按压或拉动推拉件163时推拉件能够定向移动。由于推拉件163的推拉部需要贯穿均压口125并且推拉部部分位于均压口125外，同时又需要在封堵部离开均压口后使均压口125内外连通，所以推拉部的外径小于均压口125的内径，通过设置导向部可避免推拉推拉部时推拉件163偏斜。
以下通过抽真空杯盖100的使用过程对本申请提供的抽真空杯盖100、抽真空杯以及抽真空搅拌/粉碎杯进行进一步地说明。
在利用真空杯盖抽真空时，首先将抽真空杯盖100通过连接部123与杯体200连接。
对上盖组件110施加外力，克服弹性件150的弹力使活塞130在活塞筒140内向下移动，在压力差的作用下，吸气单向阀143关闭，排气单向阀135开启，活塞130与活塞筒140之间的抽真空腔内的空气通过排气单向阀135排入活塞130的中空结构中，进一步通过活塞130顶部的排气槽133进入活塞130的外壁与上外周壁112之间的空间，再排出抽真空杯盖100。随着活塞130向下移动，抽真空腔内的容积逐渐减小，直至活塞130底壁的排气阀座134与活塞筒140底壁的第一吸气阀座142贴合，抽真空腔的容积减小至基本为零，压缩过程结构。撤去对上盖组件110施加的外力，上盖组件110在弹性件150的作用下向上移动，抽真空腔的容积逐渐增大并形成负压，吸气单向阀143开启，排气单向阀135关闭。容器内的空气通过吸气单向阀143进入抽真空腔内，直至弹性件150扩张结束，完成一个抽气循环。再次对上盖组件110施加外力，如此往复，直至容器达到所需的真空度，从而实现对容器的抽真空的目的。在每一个抽气循环中，抽真空腔内的空气均被完全排出，使抽气效率大大提高。
在容器达到所需的真空度后，可将活塞130按压至最底点后旋转上盖组件110，使导向筋的顶部抵接在凸缘结构下，避免上盖组件110在弹性件150的作用下向上移动，从而保持上盖组件110足浴压缩状态，方便容器的存放。
在需打开抽真空杯取出其内的食品时，可拉动均压阀160，使均压阀160避开均压口 125，使外界空气通过均压口125进入容器内，以方便抽真空杯盖100从杯体200上取下。
在利用抽真空搅拌/粉碎杯进行搅拌/粉碎工作前，可先对搅拌/粉碎器内进行抽真空，以减少其内的空气，以防止搅拌/粉碎过程中食品氧化。由于在搅拌/粉碎过程中可能产生气体，在搅拌/粉碎结束后，可再次利用抽真空杯盖100进行抽真空处理。
结合图8至图11，本申请提供一种抽真空杯，包括抽真空杯盖100和杯体200，所述抽真空杯盖100包括下盖组件120、上盖组件110和锁紧结构，所述下盖组件120设有与所述杯体200密封连接的连接部123；所述上盖组件110与下盖组件120之间具有容积可变的抽真空腔，所述抽真空腔设有吸气孔，所述吸气孔上设有吸气单向阀143，所述吸气单向阀143只允许气体由所述杯体200进入所述抽真空腔内，所述抽真空腔设有排气孔，所述排气孔用于从所述抽真空腔排出气体；按压所述上盖组件110上盖组件110至最低点使所述抽真空腔的容积变到最小时，所述上盖组件110能够压紧所述吸气孔上的吸气单向阀143；所述锁紧结构将所述上盖组件110和下盖组件120锁紧，使所述上盖组件110保持在压紧所述吸气孔上的吸气单向阀143的状态下。
可选地，所述杯体200设有上杯口，所述上杯口与所述抽真空杯盖100的下盖组件120的连接部123密封连接。
可选地，所述上杯口设有外螺纹，所述连接部123设有内螺纹，所述上杯口与所述连接部123通过螺纹密封连接。
可选地，当所述杯体200内达到所需的真空度后，按压所述上盖组件110至最低点使所述抽真空腔的容积变到最小，并使所述上盖组件110压紧所述吸气孔上的吸气单向阀143后，所述锁紧结构将所述上盖组件110和下盖组件120锁紧，使所述上盖组件110保持在压紧所述吸气孔上的吸气单向阀143的状态下。
在其中一个实施例中，所述抽真空杯盖100还包括活塞130和活塞筒140，所述活塞130与所述上盖组件110连接，所述活塞筒140与所述下盖组件120连接，所述活塞130能够在所述活塞筒140内密封地移动以在所述活塞130与所述活塞筒140之间形成所述抽真空腔；当所述活塞130在所述活塞筒140内移动至最低点时，所述活塞130的底壁与所述活塞筒140的底壁之间的距离最小，所述抽真空腔的容积变到最小。利用所述抽真空杯盖100对所述杯体200进行抽真空时，将所述活塞130在活塞筒140内移动至最低点时，从而使所述活塞130的底壁与所述活塞筒140的底壁之间的距离最小，所述抽真空腔的容积变到最小其内暂存的空气被完全排出抽真空腔，当活塞130移动使抽真空腔容积增大时，能够从杯体200内吸取更多的空气。
在其中一个实施例中，所述吸气孔开设于所述活塞筒140的底壁上，吸气孔上设有吸气单向阀143，吸气单向阀143只允许空气由杯体200进入抽真空腔内，所述活塞130为中空结构，所述排气孔开设于所述活塞130的底壁上，所述排气孔上设有排气单向阀135，所述排气单向阀135只允许空气从所述抽真空腔排出。通过在吸气孔设置吸气单向阀143以及在排气口设置排气单向阀135，能够有利于空气在抽真空腔内的定向流动，对空气的单向密封性能更为可靠。
在其中一个实施例中，所述吸气单向阀143靠近所述活塞130一侧的表面上设置有挤 压部311，所述锁紧结构将所述上盖组件110和下盖组件120锁紧时所述活塞130的底壁压紧所述挤压部311。所述抽真空腔内的真空度达到所需要求后，按压所述上盖组件110至最低点使所述抽真空腔的容积变到最小，并使所述活塞130的底壁压紧所述吸气单向阀143的挤压部311；所述锁紧结构将所述上盖组件110和下盖组件120锁紧，使所述活塞130的底壁保持压紧所述吸气单向阀143的挤压部311。活塞130底壁压紧吸气单向阀143的挤压部311，所述活塞130的底壁给所述吸气单向阀143提供一定的机械压力，这样就能够保证抽真空杯在倒置放置运输时，由于活塞130底壁始终给吸气单向阀143提供压力，即使杯体200内的液体在重力和冲击力作用下，吸气孔上的吸气单向阀143也不会被打开，实现了对抽真空腔的吸气孔进行有效密封，从而保证了杯体200内所需的真空度的目的。
在其中一个实施例中，所述挤压部311为设置于所述吸气单向阀143靠近所述活塞130一侧的表面上的环状凸圈。挤压部311设置成环状凸圈有利于活塞130底壁均匀地给所述吸气单向阀143提供压力。可选地，所述环状凸圈环绕所述排气口设置，即所述环状凸圈的直径大于所述排气孔的直径，从而在所述吸气单向阀143受所述活塞130底壁挤压时，所述环状凸圈密封所述排气口。
在其中一个实施例中，所述环状凸圈的截面呈三角形。环状凸圈设置成截面呈三角形的形状，所述活塞130底壁压紧所述吸气单向阀143后，既可以给吸气单向阀143提供适当的机械压力，以防止抽真空杯在倒置放置运输时，杯体200内的液体在重力和冲击力作用下，吸气孔上的吸气单向阀143被打开。又可以缓解所述活塞130底壁远离所述环状凸圈时两者之间的吸盘效应。当然地，为了减小拉开活塞130时活塞130底壁与所述环状凸圈两者之间的粘贴力，所述环状凸圈上可以间隔地设置凹槽。
在其中一个实施例中，所述活塞130外壁上设置有导向筋410，所述活塞筒140内壁上设置有与所述导向筋410配合的导向槽510，所述导向筋410与所述导向槽510配合使活塞130在活塞筒140内定向移动。在本实施例中，导向筋410沿活塞130外壁纵向设置，导向槽510仅设置在活塞筒140内壁的上端。当活塞130在活塞筒140内纵向移动时，导向筋410位于导向槽510内并受到导向槽510的限制，从而能够使活塞130在活塞筒140内的纵向相对移动更为平稳。
在其中一个实施例中，所述锁紧结构包括第一锁定结构和第二锁定结构，所述第一锁定结构设置在所述活塞130上，所述第二锁定结构设置在所述活塞筒140上，在所述抽真空腔被压缩至最小后，所述第一锁定结构与所述第二锁定结构锁定，所述活塞130的底壁保持压紧所述吸气单向阀143。这样就能够保证抽真空杯在倒置放置运输时，由于活塞130底壁始终给吸气单向阀143提供压力，即使杯体200内的液体在重力和冲击力作用下，吸气孔上的吸气单向阀143也不会被打开，实现了对抽真空腔的吸气孔进行有效密封，从而保证了杯体200内所需的真空度的目的。
在其中一个实施例中，所述第一锁定结构为所述导向筋410的顶端，所述第二锁定结构为设置于所述活塞筒140内壁顶端的导向槽510两侧的凸缘结构，当活塞130在活塞筒140内移动至最低点时，导向筋410顶端从导向槽510中脱离，旋转活塞130使导向筋410顶端抵接在凸缘结构下从而将活塞130锁定在最低位置。活塞130底壁压紧吸气单向阀143 的挤压部311，所述活塞130的底壁给所述吸气单向阀143提供一定的机械压力，确保杯体200内的液体在重力和冲击力作用下，吸气孔上的吸气单向阀143也不会被打开。
在其中一个实施例中，所述锁紧结构包括第一锁定结构和第二锁定结构，所述第一锁定结构为设置在所述上盖组件110的弹性卡槽，所述第二锁定结构为设置在所述下盖组件120的凸缘卡扣，当所述活塞130在所述活塞筒140内移动至最低点时，所述凸缘卡扣能够扣合在所述弹性卡槽中将所述上盖组件110与下盖组件120锁定，从而将活塞130锁定在最低位置。活塞130底壁压紧吸气单向阀143的挤压部311，所述活塞130的底壁给所述吸气单向阀143提供一定的机械压力，确保杯体200内的液体在重力和冲击力作用下，吸气孔上的吸气单向阀143也不会被打开。
上述抽真空杯，当杯体200内达到所需的真空度后，按压上盖组件110至最低点，使抽真空腔的容积变到最小同时使上盖组件110压紧下盖组件120吸气孔上的吸气单向阀143后，通过锁紧结构将上盖组件110和下盖组件120锁紧，将上盖组件110保持在压紧下盖组件120吸气孔上的吸气单向阀143的状态，确保了即使抽真空杯在倒置放置运输时，由于上盖组件110始终给吸气单向阀143提供压力，即使杯体200内的液体在重力和冲击力作用下，吸气孔上的吸气单向阀143也不会被打开，实现了对下盖组件120上的吸气孔进行有效密封，从而保证了杯体200内所需的真空度的目的。克服了现有的抽真空杯，抽真空杯在倒置放置运输时，杯体200内的液体容易在重力和冲击力作用下打开吸气孔上的阀体，渗漏到抽真空杯盖100部分，进而影响杯体200内真空度的缺陷。产生了抽真空杯被倒置放置运输时能够有效地防止杯体200内的液体向抽真空杯盖100内渗漏进而保证容器内所需真空度的有益效果。
