具体实施方式
请参照图1至图11所示，其显示出了本发明之较佳实施例的具体结构，包括有用于与容器10的开口部分密封配合的容器盖主体20，该容器盖主体20上设置有用于将容器10内的空气抽出外界的抽气机构30、用于指示容器10内空气是否完全抽出的真空指示组件40、用于控制该抽气机构30开启或关闭的第一开关50和第二开关60。
该容器10可为任何材质，且其开口部分可为任何形状，该容器盖主体20的形状可根据开口部分的实际形状进行设置，在本实施例中，该容器盖主体20为圆形，不以为限；以及，该容器盖主体20包括有主体上盖21和主体下盖22，该主体上盖21位于容器10外，该主体下盖22嵌入容器10的开口部分内，该主体上盖21与主体下盖22共同围构成一腔室201，前述抽气机构30、真空指示组件40、第一开关50和第二开关60均位于该腔室201内。另外，该容器盖主体20上凹设有用于安放电池以为抽气机构30提供电力供应的容置腔202，该容置腔202由一电池盖23封盖住；此外，该容器盖主体20上设置有连通容器10内部的第一通孔203、第二通孔204和气嘴205，该第一通孔203、第二通孔204和气嘴205均位于主体下盖22上。
该真空指示组件40包括有可伸缩的第一软胶管41、促使该第一软胶管41伸开的第一弹簧42、以及由该第一软胶管41作用而来回活动的指示钮43；该第一软胶管41的密闭端抵住指示钮43，第一软胶管41的开口端与前述第一通孔203密封式连通；该第一弹簧42位于第一软胶管41内并抵于第一软胶管41和容器盖主体20之间；该指示钮43露出容器盖主体20外；常压状态下，该第一软胶管41处于伸开状态，该指示钮43伸出容器盖主体20外，以指示容器10内存有空气，未达到真空状态；真空状态下，该第一软胶管41处于缩回状态，该第一弹簧42被压缩，该指示钮43缩回容器盖主体20内，以指示容器10内为真空状态。
该第二开关60与第一开关50串联连接，针对该第二开关60设置有用于自动控制该第二开关60接通或断开的控制组件70，该控制组件70位于前述腔室201内，该控制组件70包括有可伸缩的第二软胶管71以及促使该第二软胶管71伸开的第二弹簧72；该第二软胶管71的密闭端上设置有盖帽73，该盖帽73为塑胶盖帽，该盖帽73与第二开关60保持接触，该第二开关60位于盖帽73的正上方，该第二软胶管71的开口端与前述第二通孔204密封式连通；该第二弹簧72位于第二软胶管71内并抵于第二软胶管71和容器盖主体20之间，且第二弹簧72的弹力大于前述第一弹簧42的弹力；常压状态下，该第二软胶管71处于伸开状态，该第二开关60处于接通状态；真空状态下，该第二弹簧72受压缩，该第二软胶管71处于缩回状态，该第二开关60处于断开状态。
以及，该容器盖主体20的周侧面外设置有密封环80，该密封环80呈杯型，针对该密封环80于容器盖主体20上设置有用于将密封环80径向撑开而与容器10的内壁面密封贴合的撑开机构90；具体而说，在本实施例中，该撑开机构90包括有滑动环91、活动支架92以及手柄93；该滑动环91位于前述密封环80的内侧缘，该滑动环91与活动支架92固定连接并随活动支架92同步活动。
该活动支架92位于容器盖主体20内，该活动支架92包括有中心部921和环部922，该环部922的形状与滑动环91相适配，该滑动环91固定于环部922上，该中心部921的周缘向外均匀辐射出有多个筋条923，该多个筋条923的尾端均与环部922的内侧缘一体成型连接。
该手柄93位于容器盖主体20外并带动活动支架92活动，该手柄93的一端为枢接端931，另一端为操控端932，该枢接端931与容器盖主体20枢接，且该枢接端931上成型有促使活动支架92下压的偏心块933，该偏心块933通过一顶块94抵压于前述活动支架92上而促使活动支架92下压，针对该活动支架92设置有用于促使活动支架92向上复位的第三弹簧95；该偏心块933和顶块94均位于活动支架92的中心上方，该第三弹簧95位于活动支架92的中心下方；该操控端932开设有供手放置以便控制手柄翻转的通孔934；以及，该容器盖主体20的顶部凹设有与手柄93相适配的容置槽206，当手柄93处于向下翻转放平的状态下，该手柄93收纳于该容置槽206中。
此外，该手柄93一体凸伸出有用于抵压第一开关50的顶柱935，当手柄93处于向下翻转的状态下，该顶柱935抵压住该第一开关50，该第一开关50处于接通状态，当手柄93处于向上翻转的状态下，该顶柱935脱离第一开关50，该第一开关50处于断开状态。
详述本实施例的使用方法如下：
使用时，将需要存放的物品放入容器10后，将容器盖主体20的主体下盖22沉入容器10的开口部分；接着，压下手柄93，如图10和图11所示，由于手柄93具有一偏心块933，此时手柄93的偏心块933就压下顶块94，顶块94将活动支架92往下压，活动支架92就压缩第三弹簧95，由于活动支架92与滑动环91固定连接一起，该滑动环91随活动支架92作用而向下滑动，该滑动环91的斜面迫使密封环80的上端径向向外张开而挤压紧贴在容器10的内壁面上，从而起到密封的效果。
当该手柄93被压下放平后，该手柄93上的顶柱935顶下第一开关50，该第一开关50接通，同时，如图8所示，由于第二软胶管71通过第二通孔204与容器10相连通，此状态下，该第二软胶管71是伸开的，它的顶部顶住第二开关60，第二开关60也是处于接通的状态，电池的电通过第一开关50及第二开关60后供电给抽气机构30的泵体马达，泵体马达自动开始工作，开始将容器10内部的气体向外抽出。
与此同时，如图6所示，第一软胶管41的内部也是与容器10相通的，在抽气过程中，由于容器10内部形成负压，如图7所示，此时第一软胶管41开始收缩并带动指示钮43向下缩，由于第二弹簧72的弹力大于前述第一弹簧42的弹力，当第一软胶管41住下收缩时同时压缩第一弹簧42，而第二软胶管71同时亦会收缩并压缩第二弹簧72，只是第一软胶管41和第二软胶管42两者不同步往下缩，前者快后者慢。当将容器10内抽成真空时，第一软胶管41带动指示钮43到达一定位置时，此时第二软胶管71亦向下收缩，同时第二开关60亦慢慢松开，直至断开，此时电路被切断，该抽气机构30的泵体马达停止工作，而此时容器10的内部已经处于真空状态。
当容器10放置一段时间后，可能会出现漏气情况，若有空气进入容器10，容器10的内部真空度会降低，该第一软胶管41和第二软胶管71同时伸开。当第二软胶管71伸开时，其顶部压下第二开关60，此时第二开关60接通，该抽气机构30的泵体马达又开始工作，从而将进入容器10的空气抽走，随着容器10内真空度再一次加大，该第二软胶管71又开始收缩，其顶部又松开第二开关60，使得第二开关60将电路断开连接，该抽气机构30的泵体马达就停止工作。如此往复循环，始终保持容器10内真空。
当要打开容器10时，将手柄93往上打开，此时手柄93上的顶柱935脱离而松开第一开关50，当手柄93打至90度位置时，手柄93转动时由于枢接端931处的偏心块933让位，该顶块94和活动支架92在第三弹簧95的反作用下往上移动，同时带动滑动环91向上移动，而密封环80在自身的回弹力作用下，沿着滑动环91的斜面向内收缩。这样空气从容器10的内侧面周缘快速进入，使容器10的内部气压与外界气压平衡，然后，抓住手柄93往上提就可轻松地将本发明取出。
需要特别说明的是：该第一开关50亦可设计成一个独立的开关，由人手来控制开启或断开，而本发明的进气部份亦可做成一个独立的进气按钮；并且，本发明不限于是一个独立的整体部份，它亦可以将其功能分开来实现，即可将真空指示组件40和控制组件70放于容器10的顶部上，进气部份亦位于容器10的顶部，而抽气机构30可放于容器10的底部。
本发明的设计重点在于：首先，通过由第一开关和第二开关控制抽气机构开启或关闭，以彻底将容器内空气抽成真空，并配合真空指示组件指示当前容器内是否处于真空状态，以便于使用者及时发现漏气；同时，配合利用控制组件自动控制第二开关接通或断开，以实现在漏气时自动启动抽气机构而进行补偿抽气，达到永远保证容器内处于真空状态的目的，真正起到保鲜和防潮的功能，本发明结构简单，使用也很方便。其次，通过于容器盖主体的周侧面外设置有密封环，配合利用撑开机构将密封环径向撑开而与容器的内壁面密封贴合，以达到密封的目的，密封效果更好，并且操作也很方便。再者，通过于手柄一体凸伸出有顶柱，当手柄处于向下翻转的状态下，该顶柱抵压住该第一开关，该第一开关处于接通状态，当手柄处于向上翻转的状态下，该顶柱脱离第一开关，该第一开关处于断开状态，如此保证使用者不会忘记启动或关闭第一开关，从而为使用者的使用带来更多便利性。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
