Description

一种真空果汁机的自动密封接汁容器 技术领域
本发明属于真空果汁机配套设备技术领域，特别是涉及一种真空果汁机的自动密封接汁容器。
背景技术
中国发明专利第201210139784.7号中公开了一种由本发明申请人向中国知识产权局提交并获得授权的“带电动抽气泵的食品处理机及抽真空制取食料液的方法”。该食品处理机属于一种真空搅拌机，主要包括桶体、电动搅拌装置、电动抽气泵和加热装置；使用时采用密封的方式将桶体密封，并用电动抽气泵抽出桶体内的空气，然后将果蔬连皮带核与水在真空条件下由电动搅拌装置一起粉碎，并由加热装置加热而制成果蔬汁，这样不仅能够大大减少和避免食料液在粉碎、加热过程中出现氧化，以减少营养损失，而且可以保持良好的口感和外观颜色。
中国发明专利第201210123144.7中公开了一种也是由本发明申请人向中国知识产权局提交并获得授权的“带抽气功能的榨汁机”。该榨汁机主要包括进料筒、榨汁腔、接汁部、残渣部、榨汁机构、榨汁电机、抽气装置；其中进料筒处设有密封装置，进料筒、榨汁腔、接汁部、残渣部之间形成相互贯通的腔体，并且相互交接处为密封联接；抽气装置的抽气口与腔体连通，抽气装置的排气口位于腔体外部；榨汁机构设置在榨汁腔内，榨汁电机的输出轴与榨汁机构的驱动轴联接。该榨汁机能够利用抽气装置大大降低榨汁腔内的氧气含量，使榨汁腔内的食料在缺氧条件下被榨汁，从而避免其在榨汁过程中发生褐变及营养损失，从而保持果汁或蔬菜汁的营养成分及口感。这种榨汁机能够将果蔬的果汁、果渣自动分离，制得是纯果汁。
由于上述真空搅拌机和真空榨汁机的共同点是在真空中榨果蔬汁，因此果蔬汁不会出现氧化，故统称为真空果汁机。
但是，上述真空果汁机存在的问题是：不管是真空搅拌机还是真空榨汁机制得的果蔬汁必须立即食用，而不能在真空中保存，从而影响了消费者的使用方便性。

具体实施方式
下面结合附图和具体实施例对本发明提供的真空果汁机的自动密封接汁容器进行详细说明。
实施例1：
如图1所示，本实施例提供的真空果汁机的自动密封接汁容器包括接汁容器1、密封盖 2和浮力阀门装置；其中接汁容器1的上端有开口；密封盖2设置在接汁容器1的开口处，并且两者连接处设有密封圈3；密封盖2上形成有凹腔4，凹腔4凹入在接汁容器1内，凹腔4的外端口与真空果汁机的出汁口5密封连接，底部形成有进液口6。浮力阀门装置由凹腔4、进液口6、浮子7组成，浮子7设置在凹腔4的内部。浮子7在凹腔4内为自由状态，其能在自然状态下靠重力或接汁容器1内部的负压作用封堵住进液口6，而在接汁容器1内外无压差或压差微小时候、在果汁中能够在浮力作用下浮起并解除对进液口6的封堵。
如图2所示，作为本实施例的一个改进结构，所述的自动密封接汁容器还包括一个设置在凹腔4外端口处的凹腔盖13，凹腔盖13的中部形成有与真空果汁机出汁口5相互匹配的连接口16，用于连接真空果汁机的出汁口5。
所述的浮子7为球形、椭球形、楔形、锥形、圆柱形、扁平体形或其它规则/不规则形状结构；凹腔4的底部为凹圆弧状、平面状或其它规则/不规则形状，优选是与浮子7底面形状相互匹配的形状(比如浮子7底面为凸圆弧形状，则凹腔4底部为弧度匹配的凹圆弧状)。浮子7本身为空心密闭结构(比如空心浮球或空心立方体)或由泡沫塑料、泡沫橡胶、(闭孔)海绵等泡沫/海绵类材料制成的密度小于水的“浮子”，以使其能够在果汁产生的浮力作用下漂浮在水面上。浮子7表面为刚性、弹性或柔性的，优选是弹性或柔性的，以更好的对进液口6进行密封封堵。
现将本实施例提供的真空果汁机的自动密封接汁容器工作原理阐述如下：使用时首先将凹腔4的外端口或凹腔盖13上的连接口16与真空果汁机的出汁口5密封连接。真空果汁机启动后，在电动抽气泵或抽气装置的作用下，真空果汁机内部先被抽真空，进而使得本自动密封接汁容器内外产生压差，由此使得浮子7在压差作用下向上升起而离开进液口6，继而接汁容器1内部也被抽真空；待真空果汁机和自动密封接汁容器内部的压力平衡后，浮子7在重力下回落到凹腔4的底部而再次封堵住进液口6。这时真空果汁机开始按照其程序制作果汁，待制得的果汁从出汁口5流入凹腔4内部后，浮子7在果汁的浮力作用下浮起，这时果汁将通过进液口6流入接汁容器1内，果汁流入接汁容器1后，凹腔4内的果汁不足以使浮子7浮起，浮子7在重力作用下封堵住进液口6，之后真空果汁机停机；此时可利用真空果汁机自身的泄压阀解除真空状态(或者，凹腔盖13上还有图2中未示出的手动放气阀，该放气阀贯穿凹腔盖13的壁。此时打开手动放气阀，使凹腔4的空间与大气相通，解除真空果汁机及凹腔4内的真空状态)，但由于浮子7已将进液口6封堵住，所以接汁容器1内仍为真空状态(且因为此时真空果汁机内已经解除真空为常压，而接汁容器1内为真空负压，所以该压力差进一步使浮子7紧紧堵住进液口6)，这时可打开真空果汁机出汁口5与凹腔4的外端口或凹腔盖13上的连接口16之间的密封连接，而不会破坏接汁容器1内部的真空状态，使其内部的果汁得以真空保存，由此可以在一定的时间后供使用者饮用。
使用者需要饮用时候，先用手搬动浮子7使其偏移进液口6，从而解除浮子7对进液口 6的密封，再打开密封盖2即可饮用。可选地，浮子7上还带有类似手柄的构件，以方便用手搬动。
本实施例中，凹腔4相当于浮力阀门装置的“阀体”，浮子7即是“浮子”也兼有“阀芯”作用，进液口6相当于浮力阀门装置的“出口”，凹腔4的外端口或凹腔盖13的连接口16兼有浮力阀门装置“进口”作用。凹腔4的外端口也还可以是通过连接管件(图1、图2中未示出)与真空果汁机的出汁口5密封连接。
可选地，接汁容器1的侧壁或密封盖2上还有抽气口(图1、图2未示出)；抽气口处设有阀门，所述阀门是单向阀。
可选地，在所述接汁容器1的侧壁或密封盖2上还可以设有气压显示装置(图1、图2未示出)。气压显示装置是机械式气压表或电子式气压表；
气压显示装置的气压传感器设在接汁容器1内、密封盖2下方，其显示器设在密封盖2上或接汁容器1侧壁上；
机械式气压表是指针式气压表，包括气压传感器和指针式表头，气压传感器设在接汁容器1侧壁内侧、密封盖2下方(接汁容器1内侧)，指针式表头设在接汁容器1侧壁或密封盖2上；
也可以在接汁容器1侧壁上或密封盖2上设置测压孔，测压孔由弹性薄膜封堵，真空负压时候，弹性薄膜向内凹陷，以此简单显示接汁容器内的负压状态。
电子式气压表包括气压传感器、电池、检测电路及光学显示器或声音提示器，各部分之间是电连接，气压传感器设置在接汁容器1侧壁内侧、密封盖2下方(接汁容器1内侧)，电池设置在接汁容器上或密封盖上，检测电路设置在控制线路板上，光学显示器设置在接汁容器1侧壁上、密封盖2上，声音提示器设在控制线路板上。
另外，所述的凹腔4的外端口或凹腔盖13上的连接口16与真空果汁机的出汁口5间的密封连接为螺纹连接、卡扣连接、过盈连接或磁吸连接中的一种。其中磁吸连接是在凹腔4的外端口、真空果汁机的出汁口5或凹腔盖13上的连接口16至少一处设置永磁体或电磁体，同时在相对应的另一处设置铁磁性吸合件、电磁体或磁极相反的永磁体；设置在真空果汁机出汁口5处的电磁体与真空果汁机的控制电路板电连接；设置在凹腔4上端口或凹腔盖13上连接口16处的电磁体与设置在自动密闭接汁容器内或密封盖内的电池连接。
实施例2：
如图3所示，本实施例提供的真空果汁机的自动密封接汁容器包括接汁容器1、密封盖2和浮力阀门装置；其中接汁容器1、密封盖2与上述实施例1相同；浮力阀门装置由凹腔4、进液口6、浮子7组成，浮子7设置在凹腔4的内部。与实施例1的不同之处在于浮子7下面带有中间细尾部大的拉杆或T形杆8。
T形杆8由端杆9和拉杆10构成，拉杆10一端与浮子7连接，另一端与端杆9连接； 拉杆10中部至少有一部分直径小于进液口6的直径，且该部分贯穿进液口6，其上直径小于进液口6的部分与进液口6之间的间隙作为流体通道；端杆9位于接汁容器1的内部，并且长度大于进液口6的直径；当浮子7在重力或压差作用下向进液口6方向运动时候，可利用浮子7本身或拉杆10上直径大于进液口6的部位(此时该部位称之为“其它密封部件”)将进液口6封堵；
本实施例提供的真空果汁机的自动密封接汁容器工作原理与实施例1基本相同，不同的是可利用T形杆8对浮子7进行约束(如果拉杆10上靠近浮子7的部位直径大于进液口6，则也可以利用该部位对进液口6进行封堵)，以防止其偏离进液口6过大而无法复位。
中间细尾部大的拉杆(图3中未示出)中部至少有一部分直径小于进液口6并贯穿进液口6，其上直径小于进液口6的部位与进液口6之间的间隙作为流体通道；该拉杆尾部大于进液口6(该拉杆尾部的作用与上述T型杆8的端杆9相同，都是防止浮子7偏离进液口6过大无法复位。故此对拉杆尾部形状没有限制，只要大于进液口6即可)；当浮子7在重力或压差作用下向进液口6方向运动时候，可利用浮子7本身或所述拉杆上直径大于进液口6的部位(此时该部位称之为“其它密封部件”)将进液口6封堵住。T形杆8实际是“中间细尾部大的拉杆”的一个特例。
即当凹腔4内有液体时候或接汁容器1内部压力大于真空果汁机内部压力时候，浮子7浮起或升起，直接或带动其它密封部件(例如所述拉杆10上直径大于进液口6的部位)打开进液口6；
当凹腔4内没有液体、液体少到不足以使浮子7浮起、或接汁容器1内部压力小于真空果汁机内部压力时候时候，浮子7落下，直接或带动其它密封部件(例如所述拉杆10上直径大于进液口6的部位)封堵住进液口6，浮力阀门装置关闭。
实施例3：
如图4所示，本实施例提供的真空果汁机的自动密封接汁容器包括接汁容器1、密封盖2和浮力阀门装置；其中接汁容器1顶部的一侧形成有开口，密封盖2扣合在开口处；接汁容器1顶部另一侧形成有凹腔4，凹腔4的外端口与真空果汁机的出汁口5密封连接，底部形成有进液口6；浮力阀门装置由凹腔4、进液口6、浮子7组成，浮子7设置在凹腔4的内部。
本实施例提供的真空果汁机的自动密封接汁容器工作原理与实施例1相同，只是凹腔4的设置位置在接汁容器1的顶部，因此这里不再重述。
实施例4：
本实施例提供的真空果汁机的自动密封接汁容器中密封盖2和浮力阀门装置采用如下形式的结构配合使用：
如图5所示，所述的密封盖2上形成的凹腔4为长方体形，底部形成有进液口6；浮力 阀门装置由凹腔4、进液口6、浮子7、连接杆11和锥形塞12构成；浮子7、连接杆11和锥形塞12全部设置在凹腔4的内部；连接杆11的两端分别连接在浮子7和锥形塞12的顶面上，并且锥形塞12的圆锥面能够在重力或压差的作用下封堵住进液口6。
如图6所示，所述的密封盖2上形成的凹腔4为长方体形，不同处在于侧壁上形成有进液口6；浮力阀门装置还包括连接在锥形塞12下面(后面)的中间细尾部大的拉杆或T形杆。
中间细尾部大的拉杆中部至少有一部分直径小于进液口6且该部位贯穿进液口6，其上直径小于进液口6的部位与进液口6之间的间隙作为流体通道；该拉杆尾部大于进液口6，该尾部的形状可以是圆球形、圆台形或其它任意形状，其作用是防止锥形塞12清洗时候脱落；锥形塞12的圆锥面能够在重力或压差作用下封堵住进液口6。
T形杆由端杆9和拉杆10构成，拉杆10一端与锥形塞12连接，另一端与端杆9连接；拉杆10中部至少有一部分直径小于进液口6的直径，且该部分贯穿进液口6，其上直径小于进液口6的部位与进液口6之间的间隙作为流体通道；端杆9位于接汁容器1的内部，并且长度大于进液口6的直径；锥形塞12的圆锥面能够在重力或压差作用下封堵住进液口6。T型杆实际是“中间细尾部大的拉杆”的一种特例。
所述锥形塞12的形状也可是球形、椭球形、楔形、各种锥形、圆柱形、扁平体形或其它规则/不规则形状结构，只要其能够封堵住进液口6即可，故此也可以统称为密封塞；
即当凹腔4内有液体时候或接汁容器1内部压力大于真空果汁机内部压力时候，浮子7浮起或升起，直接或带动其它密封部件打开进液口6，浮力阀门装置开启；
当凹腔4内没有液体、液体少到不足以使浮子7浮起、或接汁容器1内部压力小于真空果汁机内部压力时候时候，浮子7落下，直接或带动其它密封部件封堵住进液口6，浮力阀门装置关闭。
安装有上述密封盖2和浮力阀门装置的自动密封接汁容器工作原理与上述实施例相同，因此这里不再重述。
实施例5
如图7所示，本实施例提供的真空果汁机的自动密封接汁容器包括接汁容器1、密封盖2和浮力阀门装置；其中接汁容器1的上端有开口；密封盖2设置在接汁容器1的开口处，并且两者连接处设有密封圈3；密封盖2上形成有凹腔4，凹腔4凹入在接汁容器1内，凹腔4的外端口与真空果汁机的出汁口5密封连接，底部形成有进液口6；浮力阀门装置由浮子7、凹腔4、进液口6、下浮子室18、下浮子17和连杆21构成。浮子7设置在凹腔4的内部；下浮子室18的上端固定或可拆卸地连接在位于进液口6外侧的凹腔4外壁外面上，其底部和/或侧壁上至少有一个泄流孔；下浮子17设置在下浮子室18内；连杆21的两端分别与下浮子17和浮子7相连接。
下浮子室18上的泄流孔包括底部泄流孔19和侧壁泄流孔20；其中侧壁泄流孔20分为位于侧壁靠上部位和位于侧壁靠下部位两种，优选是位于侧壁靠上部位。
另外，底部泄流孔19与位于靠下部位的侧壁泄流孔20的总面积﹤进液口6净面积(进液口6净面积＝进液口6面积减去连杆或其它构件所占面积之后的面积)，这样可使下浮子室18的底部泄流孔19和侧壁靠下部位的侧壁泄流孔20流出果汁的速度小于通过进液口6流入果汁的速度，由此使得果汁从进液口6流入下浮子室18后，有一部分果汁能够滞存在其内部，从而使下浮子17能够在浮力的作用下向上浮起。
此外，位于靠上部位的侧壁泄流孔20面积可以大于进液口6的净面积，这样可使下浮子室18内果汁过多时候能够快速流出。
下浮子室18优选为空心杯形状，其与凹腔4外表面以固定/可拆卸方式连接。
另外，连杆21为直杆或上部较粗的变径杆，连杆21上至少有一部分直径小于进液口6直径。从凹腔4内壁到下浮子室18内底部高度为H，凹腔4的壁厚为H1，下浮子17本身的高度为H2，连杆21的长度为H3，则H1+H2+H3﹤H。如H为3厘米，H1为0.3厘米，H2为0.7厘米，H3为1厘米，从而使得在下浮子室18内没有液体时候，浮子7能够自动落下，由此依靠浮子7本身或连杆21上部较粗部位封堵住进液口6。
本实施例中设置下浮子室18和下浮子17的作用是：当只带有一个浮子7的时候，在果汁流入凹腔4内且流入量足够多时会使浮子7升起，从而打开进液口6，使果汁流入接汁容器1内。但是当果汁即将完全流入接汁容器1时候，因为凹腔4内的果汁太少、浮力太小，不足以使浮子7浮起，从而导致在凹腔4内还剩余少量果汁时候，浮子7就已经落下并封堵住进液口6，使得凹腔4内残余少量液体果汁无法全部流入接汁容器1内。而带有下浮子室18和下浮子17以后，由于下浮子室18内滞存的果汁可使下浮子17浮起，从而顶到浮子7，使其滞后少许时间再完全落下并封堵住进液口6，使凹腔4内残余的果汁能够有时间完全流入接汁容器1内。
本实施例提供的真空果汁机的自动密封接汁容器在使用时候，首先将凹腔4外端口与真空果汁机出汁口5相接，真空果汁机启动后，真空果汁机内部先被抽真空，进而使得接汁容器1内外产生压差，结果使得浮子7在压差的作用下向上升起，接汁容器1内被抽真空；再进一步，真空果汁机内制得果汁从出汁口5流出、进入凹腔4内，使得浮子7再次被果汁产生的浮力浮起，继而果汁通过进液口6流入下浮子室18，再通过下浮子室18底部泄流孔19和/或侧壁泄流孔20流入接汁容器1底部。
因为底部泄流孔19和/或位于侧壁靠下部位的侧壁泄流孔20的总面积小于进液口6净面积，所以使得下浮子室18内(尤其是下部位置)总滞后存有一部分果汁，该果汁提供的浮力可使下浮子17升起(同时，下浮子室18侧壁靠上部位的侧壁泄流孔20面积较大，这使得下浮子室18内果汁较多时候，果汁能够通过更大面积的侧壁泄流孔20快速流入接汁容器 1内)。真空果汁机制作的果汁接近完全流入自动密封接汁容器1后，这时就使凹腔4内剩余的果汁不足以使浮子7浮起，但是在下浮子室18内(靠下部分)仍有液体果汁，该果汁使得下浮子17升起、并进一步(通过连杆21或直接顶起)顶起浮子7，使浮子7不能封堵住进液口6，使凹腔4内残余的果汁能够顺利流入接汁容器1内；凹腔4内果汁全部流完以后，下浮子室18内的果汁也通过底部泄流孔19慢慢流入接汁容器1内，使下浮子17下沉、浮子7也跟着下沉，最后靠浮子7下部封堵住进液口6，或靠“连杆21上部直径较粗、直径大于进液口6的部位(连杆中部、下部直径小于进液口6)”堵住进液口6。此时“连杆21上部直径较粗、直径大于进液口6的部位”称之为“其它密封部件”。
真空果汁机停机后，可利用真空果汁机自身泄压阀解除真空状态，但此时因浮子7封堵在进液口6处，故此接汁容器1内仍为真空状态，打开真空果汁机出汁口5与凹腔4外端口的密封连接，接汁容器1内仍保持真空，使果汁得到真空保存。
另外，浮子7及下浮子17为球形、椭球形、楔形、锥形、圆柱形、扁平体形或其它规则/不规则形状结构，浮子7及下浮子17本身为空心结构(比如空心浮球或空心立方体)或由泡沫塑料、泡沫橡胶、(闭孔)海绵等泡沫/海绵类材料制成的密度小于果汁(或水)的“浮子”，以使其能够漂浮于果汁上并产生浮力。浮子7、下浮子17本身也可以是由柔性材料制成(例如是橡胶球或泡沫橡胶等等)。浮子7、下浮子17表面为刚性、弹性或柔性的，优选是弹性或柔性的。
另外，下浮子17与浮子7之间只是通过连杆21传递浮力，三者之间并不相连。也还可以是浮子7与下浮子17之间不设置连杆21，两者之间也不连接。但是在下浮子17受浮力作用向上浮起后，下浮子17顶部(直径小于进液口6)能够通过进液口6顶起浮子7(或者是浮子7下面有凸出的“杆”，该“杆”穿过进液口6、伸入下浮子室18内，下浮子17浮起后顶到该“杆”，进而顶起浮子7)。只要下浮子17在下浮子室18内浮起后可以通过进液口6顶起浮子7即可。
实施例6
如图8所示，本实施例提供的真空果汁机的自动密封接汁容器包括接汁容器1、密封盖2和浮力阀门装置；其中接汁容器1的上端有开口；密封盖2设置在接汁容器1的开口处，并且两者连接处设有密封圈3；密封盖2上形成有凹腔4，凹腔4的上部侧壁凸出在接汁容器1之外(及密封盖2之上)，凹腔4的外端口与真空果汁机的出汁口5密封连接，底部形成有进液口6；浮力阀门装置由凹腔4、进液口6、浮子7、下浮子室18和下浮子17构成。与实施例5不同之处在于浮子7为椭球形状，设置在凹腔4的内部；下浮子17为圆柱体形状，上部直接贯穿凹腔4上的进液口6与浮子7连为一体，由此可以省掉实施例5中的连杆21。
下浮子17也可以是“细腰大尾”形状。“大尾”部位的直径大于进液口6，这样能够在 清洗时候避免下浮子17从进液口6处脱离出去。
可选地，连在一起的浮子7、下浮子17也可以是“中间细、两头粗的亚腰葫芦”形状或者是“哑铃”形状(哑铃上面的“头”是浮子7，下面的“头”是下浮子17，哑铃腰部的作用类似于连杆21)。
本实施例工作原理与实施例5相同，因此这里不再重述。
可选地，在所述凹腔4上凸出在密封盖2之上的侧壁处有手动放气阀F，在需要时候，打开该手动放气阀解除凹腔4内(及真空果汁机内)的真空，但是接汁容器1内仍保持真空。
实施例7
如图9所示，本实施例提供的真空果汁机的自动密封接汁容器包括接汁容器1、密封盖2和浮力阀门装置；其中接汁容器1的上端有开口；密封盖2设置在接汁容器1的开口处，并且两者连接处设有密封圈3；密封盖2上形成有凹腔4，凹腔4凹入在接汁容器1内，凹腔4的外端口与真空果汁机的出汁口5密封连接，底部形成有进液口6；浮力阀门装置由浮子7、凹腔4、进液口6、下浮子室18、下浮子17和连杆21构成。浮子7设置在凹腔4的内部；下浮子室18的上端固定或可拆卸地连接在位于进液口6外侧的凹腔4外壁外面上，其底部和/或侧壁上至少有一个泄流孔；下浮子17设置在下浮子室18内；连杆21的两端分别与下浮子17和浮子7相连接。
下浮子室18上的泄流孔包括底部泄流孔19和侧壁泄流孔20；其中侧壁泄流孔20分为位于侧壁靠上部位和位于侧壁靠下部位两种，优选是位于侧壁靠上部位。
另外，底部泄流孔19与位于靠下部位的侧壁泄流孔20的总面积﹤进液口6净面积(进液口6净面积＝进液口6面积减去连杆或其它构件所占面积之后的面积)，这样可使下浮子室18的底部泄流孔19和侧壁靠下部位的侧壁泄流孔20流出果汁的速度小于通过进液口6流入果汁的速度，由此使得果汁从进液口6流入下浮子室18后，有一部分果汁能够滞存在其内部，从而使下浮子17能够在浮力的作用下向上浮起。
此外，位于靠上部位的侧壁泄流孔20面积可以大于进液口6的净面积，这样可使下浮子室18内果汁过多时候能够快速流出。
下浮子室18优选为空心杯形状，其与凹腔4外表面以固定/可拆卸方式连接。
另外，连杆21为直杆或上部较粗的变径杆，连杆21上至少有一部分直径小于进液口6直径。在下浮子室18内没有液体时候，浮子7能够自动落下，由此依靠浮子7本身或连杆21上部较粗部位(此时该部位称之为“其它密封部件”)封堵住进液口6。
本实施例与实施例5不同之处在于：连杆21内为中空形状(或者：连杆21本身就是一个气管)，内有排气通道210。
所述浮子7的底部有凹槽71，连杆21为中空形状，内有排气通道210，连杆21的上端位于凹槽71内(或也可以是位于凹槽71外或与凹槽71朝下的开口齐平)，连杆21通过 连接件L与凹槽71的内壁固定或可拆卸连接(也可以是连杆21与凹槽71顶部或浮子7固定或可拆卸连接)，连杆21的上端部位的开口211位于凹槽71内(“上端”不一定是端头，也可以是中空形状连杆21位于凹槽71内的侧壁处有开口)、凹槽71外或与凹槽71朝下的开口齐平，连杆21下端开口位于凹腔4的外壁外部(所述“下端”不一定是下部端头，也可以是中空形状连杆21位于凹腔4的外壁外部的侧壁处有开口)，优选(图9所示)是连杆21下端进一步伸出下浮子室18的底部(穿越处即形成底部泄流孔19。此时泄流孔19的有效流通面积为孔总面积减去连杆21横截面面积)、露出在下浮子室18底部下面，且其下端开口212最好是为“喇叭”形状(以更好地避免果汁由此反向进入中空形状连杆21内的排气通道内)，由此使得连杆21内的排气通道210一端与凹槽71内空间连通，另一端与接汁容器1内空间连通。
浮子7的底部带有凹槽71后，当凹腔4内没有果汁(或水)时候，浮子7在重力作用下仍将进液口6封堵住(此时凹槽71朝下的开口也被压在凹腔4的底部，并被凹腔4的底部封堵住。所述凹槽71朝下的开口为弹性的或刚性的)。当凹腔4内有果汁时候，浮子7在浮力作用下升起，使进液口6打开，同时也使凹槽71朝下的开口位于果汁液面附近(位于液面之上、液面处或液面下)。
本实施例中，连杆21为中空形状且内有排气通道210的作用是：真空果汁机启动后，接汁容器1内被抽真空(如前述)，达到真空值假设为-85KPA，接汁容器1的容积假设为1200毫升。果汁通过进液口6流入接汁容器1内以后，随着果汁的流入，接汁容器1内的剩余空间(容积)越来越小，使得接汁容器1内的气体压力逐渐升高(真空度逐渐降低)，此时，接汁容器1内的多余空气就会从中空形状连杆21下端开口212进入其内的排气通道210内，并进一步通过其上端开口211进入凹槽71内，再进一步从凹槽71朝下的开口处排出到凹腔4内(此时，即便凹槽71朝下的开口位于果汁液面以下，则因为该开口的水平位置高于中空形状连杆21下端开口212的水平位置，同时，此时凹腔4内的气压也低于接汁容器1内的气压，故此这两个“开口”之间存在一个压力差，该压力差使得抽气通道210内的空气可以从凹槽71朝下的开口处排出)，并进一步被真空果汁机的电动抽气泵排出。使得接汁容器1内不至于因流入果汁而气压升高，可避免因接汁容器1内压力过高而使果汁不能顺畅流入的问题，从而保证了果汁能顺畅地流入接汁容器1内。当凹腔4内的果汁全部流入接汁容器1内，浮子7及下浮子17落下，将进液口6封堵，从而保持接汁容器1内的真空。
本实施例中，所述的浮子7的底部也可以是没有凹槽71，仅仅只是平面形状、凹弧形状或凸弧形状，所述中空形状连杆21的上端开口211位于浮子7的底部下方(上端开口211与浮子7的底部留有一定距离或间距)。连杆21下端开口212位于凹腔4的外壁外面并与接汁容器1内空间连通，或者连杆21下端穿过底部泄流孔19伸出下浮子室18的底部下面， 连杆21下端开口212位于接汁容器1内，连杆21内的排气通道210一端与浮子7底部空间连通，另一端与接汁容器1内空间连通。同样可以达到相同或类似的效果。
本实施例中，所述的浮子7的底部的凹槽71(或者浮子7的底部没有凹槽71，而是平面形状或凸弧形状等)、中空形状连杆21、浮子7、凹腔4的底部等等同时也共同构成了“单向阀”。也就是说：浮子7、中空形状连杆21、凹腔4的底部所构成的不仅仅只是浮力阀门装置，还同时具有排出接汁容器1内多余空气的作用。
可选地，下浮子室18还可以是固定或可拆卸地连接在接汁容器1的开口处与密封盖2之间(卡在这两者之间)、接汁容器1内侧壁或接汁容器1底部。其功能作用与下浮子室18固定或可拆卸连接在凹腔4外壁表面或密封盖2下方一样。
实施例8
如图10所示，本实施例与实施例7不同之处在于：浮子7内没有凹槽71，连杆21内为中空形状(或者：连杆21本身就是一个气管)，内有排气通道210，连杆21穿过浮子7，且在浮子7表面处(上表面或侧表面)或表面上部有开口211。开口211处有单向阀D(图10中为示意)，单向阀D允许的流体流通方向是：只允许流体从接汁容器1内流向凹腔4内。
连杆21下端开口位于凹腔4的外壁外部(所述“下端”不一定是下部端头，也可以是中空形状连杆21位于凹腔4的外壁外部的侧壁处有开口)，优选(图10所示)是连杆21下端进一步伸出下浮子室18的底部(穿越处即形成底部泄流孔19。此时泄流孔19的有效流通面积为孔总面积减去连杆21横截面面积)、露出在下浮子室18底部下面，且其下端开口212最好是为“喇叭”形状(以更好地避免果汁由此反向进入中空形状连杆21内的排气通道内)，使连杆21内的排气通道210与接汁容器1内空间相互连通，由此使得连杆21的排气通道210一端与凹腔4内空间连通，另一端与接汁容器1内空间连通。
本实施例中，连杆21为中空形状且内有排气通道210的作用是：真空果汁机启动后，接汁容器1内被抽真空(如前述)，达到真空值假设为-95KPA，接汁容器1的容积假设为800毫升。果汁通过进液口6流入接汁容器1内以后，随着果汁的流入，接汁容器1内的剩余空间(容积)越来越小，使得接汁容器1内的气体压力逐渐升高(真空度逐渐降低)，此时，接汁容器1内的多余空气就会从中空形状连杆21下端开口212进入其内的排气通道210内，使位于浮子7上表面处的连杆21的开口211处的单向阀D开启，多余空气进一步流入凹腔4内，并被真空果汁机的电动抽气泵排出。使得接汁容器1内不至于因流入果汁而气压升高，可避免因接汁容器1内压力过高而使果汁不能顺畅流入的问题，从而保证了果汁能顺畅地流入接汁容器1内。当凹腔4内的果汁全部流入接汁容器1内，浮子7及下浮子17落下，将进液口6封堵；当凹腔4内的气压与接汁容器1内的气压相等时候，单向阀D自动关闭，从而保持接汁容器1内的真空。
实施例9
如图11所示，本实施例提供的真空果汁机的自动密封接汁容器包括接汁容器1、密封盖2和浮力阀门装置；其中接汁容器1的上端有开口；密封盖2设置在接汁容器1的开口处，并且两者连接处设有密封圈3；密封盖2上形成有凹腔4(本实施例中，凹腔4的外径基本与接汁容器1外径相同。即密封盖2上整体形成有凹腔4，凹腔4是覆盖在接汁容器1的开口处)，凹腔4的上部侧壁凸出在接汁容器1之外，凹腔4的外端口与真空果汁机的出汁口5密封连接，底部形成有进液口6；浮力阀门装置由凹腔4、进液口6、浮子7、下浮子室18和下浮子17构成。浮子7为椭球形状，设置在凹腔4的内部；下浮子17为圆柱体形状，上部直接贯穿凹腔4上的进液口6与浮子7连为一体。下浮子室18连接在凹腔4的外壁表面上。
浮子7及下浮子17内为中空形状，内有排气通道210，排气通道210在浮子7表面处(上表面或侧表面)或表面上部有开口211。开口211处有单向阀D(图11中为示意)，单向阀D允许的流体流通方向是：只允许流体从接汁容器1内流向凹腔4内。
下浮子17的尾部(优选是该尾部直径较小)穿过下浮子室18的底部(穿越处即形成底部泄流孔19。此时泄流孔19的有效流通面积为孔总面积减去下浮子17尾部横截面面积)、露出在下浮子室18底部下面，其下端开口212位于接汁容器1内。由此使得排气通道210一端与凹腔4内空间连通，另一端与接汁容器1内空间连通。
本实施例中，浮子7和下浮子17内为中空形状且内有排气通道210的作用是：真空果汁机启动后，接汁容器1内被抽真空(如前述)，达到真空值假设为-92KPA，接汁容器1的容积假设为900毫升。果汁通过进液口6流入接汁容器1内以后，随着果汁的流入，接汁容器1内的剩余空间(容积)越来越小，使得接汁容器1内的气体压力逐渐升高(真空度逐渐降低)，此时，接汁容器1内的多余空气就会从排气通道210的下端开口212进入其内，使位于浮子7上表面处的开口211处的单向阀D开启，多余空气进一步流入凹腔4内，并被真空果汁机的电动抽气泵排出。使得接汁容器1内不至于因流入果汁而气压升高，可避免因接汁容器1内压力过高而使果汁不能顺畅流入的问题，从而保证了果汁能顺畅地流入接汁容器1内。当凹腔4内的果汁全部流入接汁容器1内，浮子7及下浮子17落下，将进液口6封堵；当凹腔4内的气压与接汁容器1内的气压相等时候，单向阀D自动关闭，从而保持接汁容器1内的真空。
可选地，所述凹腔4的侧壁或凹腔盖13上还有抽气口C；抽气口C处优选设有阀门(图11中未示出)，所述阀门是单向阀(单向阀的流通方向是：仅允许流体从凹腔4内流向凹腔4之外)。所述凹腔4的侧壁优选是全部或部分凸出于接汁容器1之外，该侧壁上有抽气口，抽气口处优选设有单向阀。
实施例10
如图12所示，本实施例提供的真空果汁机的自动密封接汁容器包括接汁容器1、密封盖 2和浮力阀门装置；其中接汁容器1的上端有开口；密封盖2设置在接汁容器1的开口处，并且两者连接处设有密封圈3；密封盖2上形成有凹腔4，凹腔4的上部侧壁凸出在接汁容器1之外，凹腔4的外端口与真空果汁机的出汁口5密封连接，底部形成有进液口6；浮力阀门装置由凹腔4、进液口6、浮子7、下浮子室18和下浮子17构成。浮子7为椭球形状，设置在凹腔4的内部；下浮子17为圆柱体形状，上部直接贯穿凹腔4上的进液口6与浮子7连为一体。下浮子室18连接在凹腔4的外壁表面上。
下浮子17(和/或浮子7)内为中空形状，内有排气通道210，排气通道210在下浮子17靠上部位侧壁处有开口211(下浮子室18内有果汁时候，下浮子17在浮力作用下升起，使该开口211与凹腔4内空间连通)。
下浮子17的尾部(优选是该尾部直径较小)穿过下浮子室18的底部(穿越处即形成底部泄流孔19。此时泄流孔19的有效流通面积为孔总面积减去下浮子17尾部横截面面积)、露出在下浮子室18底部下面，其下端开口212位于接汁容器1内并与接汁容器1内空间连通。
本实施例中，下浮子17内为中空形状且内有排气通道210的作用是：真空果汁机启动后，接汁容器1内被抽真空(如前述)，达到真空值假设为-92KPA，接汁容器1的容积假设为900毫升。果汁流入凹腔4后，首先使浮子7及下浮子17浮起(升起)，使位于下浮子17靠上部位侧壁处开口211暴露在凹腔4内(同时使排气通道210将凹腔4的空间与接汁容器1空间连通)，也使得进液口6打开，使果汁通过进液口6流入接汁容器1内，随着果汁的流入，接汁容器1内的剩余空间(容积)越来越小，但由于排气通道210将凹腔4的空间与接汁容器1空间连通，使得接汁容器1内的多余空气从排气通道210的下端开口212进入其内，再进一步通过开口211流入凹腔4内，并被真空果汁机的电动抽气泵排出。使得接汁容器1内不至于因流入果汁而气压升高，可避免因接汁容器1内压力过高而使果汁不能顺畅流入的问题，从而保证了果汁能顺畅地流入接汁容器1内。当凹腔4内的果汁全部流入接汁容器1内，浮子7及下浮子17落下，将进液口6封堵(此时，即使下浮子17靠上部位侧壁处开口211没有被封堵住，则因为开口211的位置是在接汁容器1内，所以不影响浮子7底部对进液口6的封堵)，从而保持接汁容器1内的真空。
或者，本实施例中，浮子7与下浮子17内都是中空形状，内有排气通道210。排气通道210在浮子7底部有朝下的开口211(图12中未示出)，当凹腔4内没有果汁(或水)时候，浮子7在重力作用下仍将进液口6封堵住(此时排气通道210在浮子7底部朝下的开口211也被压在凹腔4的底部)。当凹腔4内有果汁时候，浮子7在浮力作用下升起，使进液口6打开，同时也使朝下的开口211位于果汁液面附近(位于液面之上、液面处或液面下)。同样可以起到排出接汁容器1内多余空气的作用。
实施例11
如图13所示，本实施例与实施例5不同之处在于：凹腔4凹入在接汁容器1内的部分的底部或凹腔4凹入在接汁容器1内的部分的侧壁上有通孔，该通孔处有单向阀D(图13中为示意)，所述单向阀D所允许的流体的流通方向是从接汁容器1内流向接汁容器1之外(凹腔4内)。
其作用是：真空果汁机启动后，接汁容器1内被抽真空(如前述)，达到真空值假设为-90KPA，接汁容器1的容积假设为1000毫升。果汁通过进液口6流入接汁容器1内以后，随着果汁的流入，接汁容器1内的剩余空间(容积)越来越小，使得接汁容器1内的气体压力逐渐升高(真空度逐渐降低)，当接汁容器1内的压力高于真空果汁机内的压力时候，单向阀D开启，使接汁容器1内的气体进入真空果汁机内(再进一步被电动抽气泵抽出)，可避免因接汁容器1内压力过高而使果汁不能顺畅流入的问题，从而保证了果汁能顺畅地流入接汁容器1内。当接汁容器1内气体压力等于或小于真空果汁机内的压力时候，则该单向阀自动关闭，从而保持真空。单向阀可以是现有真空保鲜罐中通常使用的硅胶“工字阀(只允许气体单向流通，反向则自动关闭)”或其它现有技术的单向阀等等。
所述单向阀D还可以是设置在接汁容器1的顶部或侧壁、密封盖2、凹腔盖13、凹腔4的底部或凹腔4的侧壁。
当所述单向阀D是设置在接汁容器1的顶部或侧壁、密封盖2、凹腔盖13等等部位处时候，因为单向阀的另一端是连通大气环境，所以必须是接汁容器1内的气压大于大气环境气压时候单向阀D才能开启。
可选地，所述密封盖2上、凹腔4的外端口处或凹腔盖13的连接口16处还设有保护盖(二者以螺纹、卡扣、磁吸或过盈中的任一种方式连接)，以便于外出携带和储存。保护盖在图13中未示出。
可选地，所述保护盖的下面设有能够抵压住浮子7和/或单向阀D的结构(或装置)，所述保护盖盖上以后，抵压住浮子7或单向阀，以使其固定(不能开启或不能动)，以避免携带或晃动时候自动密封接汁容器内部的果汁流出。具体是采用下列结构形式之一：
①、保护盖的下底面是平面形状、凹弧形状或凸弧形状，浮子7上端的高度足够高，在保护盖盖上以后，保护盖下底面自然抵压住浮子和/或单向阀，使浮子被抵压后固定住不能动，使单向阀被抵压后不能开启；
或者
②、保护盖的下底面下方设有向下凸出的凸起，在保护盖盖上以后，保护盖下底面下方的凸起自然抵压住浮子和/或单向阀，使浮子被抵压后固定住不能动，使单向阀被抵压后不能开启。
可选地，所述凹腔4的全部底部及全部侧壁凸出于接汁容器1之外，或凹腔4的部分底 部及全部侧壁凸出于接汁容器1之外。其仍然能达到本发明所述功能和效果。
