一种榨汁机的压榨模组 技术领域
本发明涉及榨汁设备，具体涉及一种榨汁机的压榨模组。
背景技术
为了健康的生活，人们一般喜欢在家中直接制作和饮用果蔬的汁液，现在市面上已有大量能够从蔬果中简单提取汁液的装置。现有技术中汁液提取装置主要有果汁机，其启动机器以后，电机带动刀网高速旋转，把水果蔬菜从加料口推向刀网，刀网的尖刺将果菜削碎，在刀网高速运转所产生榨汁机的离心力的作用下，果渣飞出刀网进入渣盒，而果汁穿出刀网流入果汁杯；其次还有搅拌机，其用电机带动刀片高速旋转以达到搅拌、粉碎、切割食物的目的。
然而，无论是果汁机还是搅拌机，都只进行一次破碎即提取汁液，也即在提取汁液前，需要将完整的水果或蔬菜先切割成较小块后，才能利用刀片的高速旋转破碎以提取汁液。故此类汁液提取装置需要对果蔬预切割成小块，提取效率不高，费时费力。
发明内容
为克服上述现有技术的缺陷，本发明提供一种榨汁机的压榨模组，该压榨模组具有预压榨空间，能预压榨进入榨汁机杯体内的食材，使之成为小块后再在杯体的渣液分离区进行充分有效的压榨操作，不需要对大块食材进行小块分割操作，榨汁机的操作效率更高，食材压榨更充分，汁液提取率也越高。

为实现本发明的上述目的，本发明方案三还提供具有第三种结构的榨汁机的压榨模组，该压榨模组包括一杯体，其下侧设置有一汁液排出口；一滤网，容置于所述杯体内部；一螺旋，容置于所述滤网内部，所述螺旋的旋转轴沿垂直方向设置；一杯盖，连接于所述杯体上侧，所述杯盖下方与所述螺旋的转轴上端耦合，且所述杯盖向上形成有一中空柱体结构的进料通道，用以导引食材进入滤网；
所述杯盖的下表面靠近所述螺旋的位置处设有一凸沿；
还包括导面，形成于所述杯体内侧，所述导面设置于所述进料通道的下缘，且所述导面为一凹面并朝所述螺旋的旋转轴方向倾斜；
如此，所述杯盖下表面与所述杯体的导面及垂直高度高于所述滤网与所述导面的相连接处最低位置的所述杯体内部形成一预压榨空间，食材经由所述进料通道进入所述预压榨空间进行预压榨。
在上述三种方案的基础上，对压榨模组的结构进行进一步的优化。
进一步的，所述滤网侧边形成有一进料开口，且所述进料开口与所述导面外缘相适应。
初压榨后的食材经由与导面外缘相适应的进料开口进入滤网形成的汁液提取空间内。

具体实施方式
实施例1
如1-2图示，榨汁机的压榨模组，包括杯体1，其下侧设置有一汁液排出口4以及残渣排出口3；杯体1内部容置有一滤网7，该滤网用作渣液分离，即用于分离汁液与汁液提取过程中产生的食材残渣；该滤网7内容置有一螺旋8，该螺旋8经由旋转轴9带动旋转以对食材进行旋转切割；杯体1上盖设有一杯盖2，杯盖2的下方与上述螺旋8的旋转轴9上端耦合，且该杯盖2向上形成有一中空柱体结构的用以导引食材进入滤网7内的进料通道5，杯盖2包含一设置于进料通道5上方的旋盖部6，该旋盖部6的侧缘向下凸伸形成一进料口，该进料口的内径小于进料通道5的内径，藉由该向下凸伸的进料口，食材得以顺利进入进料通道内。
再如图2-3图示，该杯体1内侧形成有一导面11，该导面11为设置于进料通道5的下缘且向上述螺旋8的旋转轴9的方向倾斜的凹面，具体的，该导面11的上端与所述进料通道的下端相连接，以使得进料通道内的食材可以经由导面进入预压榨空间；滤网7侧边形成有一进料开口73，该进料开口73与上述导面11的外缘相适应。
再进一步结合图3及图5图示，所述导面11设置有凹台12，所述进料开口73向滤网外侧延伸有凸台75，在安装时，所述凹台12与所述凸台75相适配卡合，以使得滤网7于压榨过程中保持相对稳定性，并保证压榨过程中食材能更好地向下被导引至滤网7的下层进行研磨压榨步骤。
结合上述杯体1、杯盖2及滤网7的描述，在杯盖2下表面与杯体1的导面11及垂直高度高于该进料开口最下缘的滤网1内部形成预压榨空间，食材经由进料通道5进入该预压榨空间内进行预压榨。具体的说，压榨模组的预压榨空间包含一压榨空间上侧，所述压榨空间上侧为所述滤网7上缘表面延伸至所述导面11上缘表面；一压榨空间下侧，为所述进料开口73最下端的滤网内部横切面，所述压榨空间上侧的表面积大于或等于所述压榨空 间下侧的表面积。
再进一步结合图4，滤网7上侧内表面(也即预压榨空间内部的侧壁)上设置有多个朝向螺旋8的旋转轴9的方向凸伸的长条状的凸肋74，该凸肋74协助于压榨进行时起到抓持食材的功能，增加食材在压榨提取汁液区域的压榨效率；此外，该滤网7外表面设置有多条环状加强肋71，滤网7下侧空间为汁液过滤部72。
本发明提供具有上述结构的榨汁机的压榨模组，其杯盖下表面与杯体的导面以及垂直高度高于进料开口最下缘的滤网内部形成预压榨空间，食材经由进料通道并经由倾斜的导面进入上述预压榨空间内，螺旋旋转以将食材压榨成小块，小块化后的食材再经由于导面下缘相适应的进料开口进入滤网内，继续在螺旋与滤网内侧凸肋的共同作用下被充分挤压压榨，汁液再经滤网过滤后经由汁液排出口导出。
上述压榨模组利用预压榨空间对食材进行预压榨，在提取汁液前无需人工先将大块食材切割成小块，故而榨汁机的压榨操作更为方便高效，食材经过充分的压榨，汁液提取率也越高。
实施例2
参阅图6，该结构与实施例1中压榨模组的区别在于：其杯盖2的下表面靠近所述螺旋8的位置处设有一凸沿21，在本实施例中，该凸沿21为弧状凸沿；通过设置凸沿21，当果蔬等食材进入到预压榨空间内进行预压榨时，其凸沿21可以缩短果蔬与螺旋8之间的距离，即增加了果蔬与螺旋8之间的接触面积，使得果蔬的压榨更完全，从而提高了果蔬的压榨效率。此外，该凸沿21的厚度应当根据螺旋8的轴径大小来设置，只需要保证凸沿21与螺旋8保持一定的间距即可。
另外，在凸沿21的内弧面上靠近导面11的位置处还设有若干肋板211，在本实施例中，该肋板211呈长方形状且沿凸沿弧面环状分布，其数量为五个。当然，在其他实施例中，其肋板211的形状也可以为方形等其他形状；其数量可以多于或少于五个，在此处均不做限制。通过在凸沿21的内弧面上靠近导面11的位置处设置肋板211，第一是可以更好的让果蔬集中在此处；第二是在预压榨的过程中，肋板211可以有效阻挡果蔬因离心力的作用而往外飞溅；第三是其肋板211可以增大果蔬与螺旋8之间的挤压力，使得果蔬的压榨更完全，提高果蔬的压榨效率。
另外，凸沿21的内弧面往旋转轴9的中心方向还延伸有一曲面台阶212，在预压榨的 过程中，其曲面台阶212配合螺旋8可以对果蔬进行更加充分地压榨，从而进一步地提高果蔬的压榨效率。
根据上述说明书的揭示和教导，本发明所属领域的技术人员还可以对上述实施方式进行变更和修改。因此，本发明并不局限于上面揭示和描述的具体实施方式，对本发明的一些修改和变更也应当落入本发明的权利要求的保护范围内。此外，尽管本说明书中使用了一些特定的术语，但这些术语只是为了方便说明，并不对本发明构成任何限制。
