一种快速自动进料的挤压式榨汁机
本申请要求于2014年4月24日提交中国专利局、申请号为201410167695.2、发明名称为“一种快速自动进料的挤压式榨汁机”的中国专利申请，于2015年3月18日提交中国专利局、申请号为201520152370.7、发明名称为“一种立式螺杆挤压榨汁机”的中国专利申请，及于2015年3月18日提交中国专利局、申请号为201510117862.7、发明名称为“一种立式螺杆挤压榨汁机”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及一种食品加工机，特别是一种家用挤压式榨汁机。
背景技术
现有立式挤压式榨汁机有二类：
第一类是专利号CN200780001269.X公开的一种榨汁机，包括盖、外壳、螺杆、与螺杆配合的网孔筒、旋转刷与驱动单元，其盖的一侧设入料端口，该种榨汁机利用液体向下流动的特性，解决了不同浓淡的果汁的榨取问题，同时由于机座设置在底部，机器的稳定性好。但是，该方案的入料口设置在螺杆上方，物料进入外壳后，是落在螺杆的螺旋上方的，不容易进料，同时物料如果落入接近轴心位置，由于轴心位置转速为零，也使得进料较慢，而且也会造成物料堆积，影响下一步的挤压粉碎，另外，该结构较难实现大口径入料。
第二类是专利号201310175466.0的方案公开的一种采用入料口底部区域以偏置方式位于一个直径与所述压榨处理部位的直径相对应且以螺旋的中心轴为圆心的圆的半圆区域内，即入料口偏置实现口径做大到至少40mm以上。该方案虽然解决了物料落入轴心的问题，及在一定程度上解决了入料口径问题，但是需要在盖体底部设置凹陷，形状不规则， 即入料口口部尺寸到底部尺寸是由大变小的，其缺陷是只适用于球形物料榨汁，如苹果、番茄等，对于较粗的胡萝卜、黄瓜等条形物料的榨汁容易卡料，对物料的多样性适应较差，而且加工难度大，同时由于其入料口仍然是设置在螺杆上方，虽然入料顺畅度有所缓解，但仍然无法解决自动进料问题。
因此，无论是上述第一类小口径立式螺旋挤压榨汁机，还是上述第二类可以实现大口径进料的立式螺旋挤压榨汁机，其进料口都设置在螺杆上方，即使偏心设置，但是由于空间有限，物料仍然有距离螺杆中心较近的点，部分物料还是不易被螺旋咬入，导致进料缓慢，加工效率偏低；而且其螺杆主要是依靠切料筋条的径向力来切断物料，产生较大的扭矩，加大电机的工作负载，仍然产生容易卡料问题。
发明内容
为了解决上述技术问题，本发明提供一种能够快速自动进料的挤压式榨汁机，该榨汁机结构不但能够实现快速自动进料而且可以轻松实现大口径进料。
本发明是通过以下具体技术方案实现的：
一种快速自动进料的挤压式榨汁机，包括机座、设置在机座内的电机和驱动单元、挤压螺杆、与挤压螺杆配合挤压物料的压榨组件、及进料组件，所述压榨组件安装在机座上，所述压榨组件包括压榨腔，压榨腔上设有出汁口和出渣口，所述挤压螺杆包括螺杆轴和螺杆本体，螺杆本体包括挤压部，所述挤压部上设有挤压螺旋，所述压榨腔套在挤压螺杆外，电机通过传动机构与螺杆轴动力连接，其特征在于：所述压榨腔上设有进料口，所述螺杆本体还包括将物料向下引导的物料推进部，所述物料推进部对应进料口设置，所述进料组件包括与所述进料口连接的进料通道，所述进料通道两端口的几何中心的连线与竖直平面的夹角为a，0°≤a≤80°。
进一步的，所述进料通道为直圆管，所述a满足30°≤a≤60°。
进一步的，压榨腔包括压榨腔本体、压榨腔上盖，所述进料口设置在压榨腔本体的上部。
所述压榨腔还可以采用如下结构：所述压榨腔包括压榨腔本体、压榨腔上盖，所述压榨腔上盖设有向上凸出并用于容纳挤压螺杆上部的容纳部，所述进料口及与进料口连接的所述进料通道设置在所述容纳部的侧壁上，所述物料推进部对应容纳部的进料口设置，所述进料口的等效直径与容纳部的等效直径的比值为2/3至4/3。进一步的，所述压榨腔还包括压榨腔下盖，所述压榨腔下盖与压榨腔本体合为一体结构，出渣口设置在所述压榨腔下盖的底部，所述压榨腔下盖上设有排汁通道，所述出汁口设置在压榨腔本体的下端，排汁通道与出汁口连通。
或者，所述压榨腔还可以采用如下结构：所述压榨腔包括容纳物料推进部的上压榨腔和容纳挤压部的下压榨腔，所述上压榨腔和下压榨腔可拆卸连接，所述上压榨腔包括上压榨腔本体和压榨腔上盖，所述进料口及与进料口连接的所述进料通道设置在所述上压榨腔本体的侧壁上，所述物料推进部对应上压榨腔本体的进料口设置，所述进料口的等效直径与上压榨腔本体的等效直径的比值为2/3至4/3。进一步的，所述压榨腔上盖与上压榨腔本体合为一体结构，所述压榨腔还包括压榨腔下盖，出渣口设置在所述压榨腔下盖的底部，所述压榨腔下盖上设有排汁通道，所述出汁口设置在下压榨腔的下端，排汁通道与出汁口连通。
进一步的，所述物料推进部是设置在螺杆本体上的推进螺旋，所述推进螺旋的螺距与进料口的等效直径的比值为1/2至3/2。
进一步的，所述进料通道包括上端口和下端口，下端口与压榨腔本体上的进料口连接，上端口设有进料通道盖。
进一步的，所述进料组件还包括辅助进料口，所述辅助进料口设置在进料通道盖上，所述辅助进料口的直径为φ，φ≤45mm。或者所述辅助进料口设置在压榨腔上盖上，所述辅助进料口的直径为φ，φ≤45mm。
进一步的，所述压榨组件还包括挤压筒，所述挤压筒设置在压榨腔本体内，挤压筒内壁上设有与挤压螺旋配合的挤压筋条。
进一步的，所述压榨组件还包括过滤部，所述过滤部为设置在挤压筒上的过滤网孔或过滤栅条。
本发明中，所述“进料口的等效直径”是指进料口的最大内切圆直径；所述“上压榨腔本体的等效直径”是指上压榨腔本体的最大内切圆直径。所述“容纳部的等效直径”是指容纳部的最大内切圆直径。
本发明的有益效果是：
由于本发明将进料口及进料通道设置在压榨腔上，所述物料推进部对应压榨腔的进料口设置，使得物料依靠自身的重力能够很快经进料通道直接进入压榨腔内，并在进料口对应位置的物料推进部的向下导引作用下快速带入挤压螺旋与压榨腔形成的间隙内进行挤压，轻松实现快速自动进料。由于进料通道两端口的中心连线与竖直平面设有一夹角a，所述0°≤a≤80°，使得物料和螺杆中心轴成同样的夹角，则物料依靠自身重力及进料通道与竖直面的夹角作用下，更容易自动进入压榨腔本体及进料口处对应设置的挤压螺杆的物料推进部，而且由于此夹角a的存在，物料对挤压螺杆的冲击力被分解为轴向和水平方向，因此，物料对螺杆的螺旋方向的挤压力变小，使得电机扭矩变小，有效降低了电机负载，不但进料更顺畅，而且电机稳定寿命长。同时，物料被推进螺旋咬断，并在其作用下，迅速被带入挤压螺旋和压榨腔本体的间隙内，使得物料被挤压出汁。
另外，由于进料口设置在压榨腔上，则进料口径的大小及位置不必受螺杆及压榨腔上盖的尺寸影响，可以轻松实现大口径入料，同时当采用大口径时，由于进料通道两端口的几何中心连线与竖直平面呈夹角a，所述0°≤a≤80°，相当于斜向放料，能有效防止人的手伸入进料通道过深，同时使得进料通道相对于竖直放置的管道变长，产品的安全性更高，而且该产品结构简单，易加工成型。当a大于80°时，进料通道过于平缓，物料与进料通道的摩擦力较大，不利于快速进料，降低了榨汁效率。
当所述进料通道为直圆管，所述a满足30°≤a≤60°时，自动进 料效果更佳，电机负载更小且更加稳定。所述进料通道设置在压榨腔的上部，更有利于进料和压榨。当a小于30°时，虽然能实现快速落料，但物料到达下端口时与挤压螺杆的中心距离较近，挤压螺杆的转速较小，承受的扭矩较大，不利于物料的咬入和初步粉碎。
所述进料组件还包括辅助进料口。所述进料通道的口部还设有进料通道盖，所述辅助进料口设置在进料通道盖上，所述辅助进料口的直径为φ，φ≤45mm；或者所述辅助进料口设置在压榨腔上盖上，所述辅助进料口的直径为φ，φ≤45mm。这样，不但满足了安规对于口径尺寸的要求，而且可以实现随时加料，对于较大物料，我们通过进料通道放入，而后合上进料通道盖，开机榨汁，然后将较小物料通过设置在进料通道盖或者压榨腔上盖的辅助进料口加入，而不必开盖停机，对于制作不同大小物料的混合果汁，非常方便实用。而对于挤压较硬的物料比如胡萝卜、土豆、红薯时，可以将较硬物料从压榨腔上盖的辅助进料口加入，采用此种结构不但使得挤压出汁更充分，而且榨出的土豆泥、胡萝卜泥、红薯泥更细腻，方便顾客将其作为食物配料使用。
而当用来挤压坚果类物料比如核桃、花生等物料与水果混合制作内含坚果颗粒的果汁时，可以使用不设过滤网的挤压筒与挤压螺杆配合制作。将坚果从进料通道盖上的辅助进料口加入，同时调节挤压间隙，可以不必停机直接压榨，能够压榨出满足颗粒感的坚果颗粒，而后将榨出的核桃颗粒、花生颗粒等放入挤压出的果汁杯内，方便制作混合饮料。另外也可以用此挤压筒和挤压螺杆配合挤压的结构制作含果粒的冰激凌。
所述物料推进部是设置在螺杆本体上的推进螺旋，挤压螺杆的物料推进部将物料向下导引，推进螺旋将物料咬断进行初步粉碎后沿推进螺旋将物料快速带入挤压研磨部与下压榨腔形成的间隙内进行挤压榨汁。推进螺旋的螺距与进料口的等效直径的比值为1/2至3/2，当物料通过进料通道后能够顺利进入推进螺旋，被推进螺旋咬断并沿推进螺旋向下被带入挤压螺旋与压榨腔形成的间隙内进行挤压榨汁，实现快速榨汁。 当推进螺旋的螺距与进料口的等效直径比值小于1/2时，物料通过进料通道后不能够顺利进入推进螺旋，而且螺距相对较小使得物料无法被快速带入到挤压螺旋，影响榨汁效率。当比值大于3/2时，物料相对于螺距较小，物料不易被咬断，不能达到预粉碎的目的。

具体实施方式
如图1至16所示的快速自动进料的挤压式榨汁机，包括机座1、设置在机座1内的电机6和驱动单元(图中未示出)、挤压螺杆2、与挤压螺杆2配合挤压物料的压榨组件、进料组件7，所述压榨组件安装在机座1上，所述压榨组件包括压榨腔4，压榨腔4上设有出汁口41和出渣口42，所述挤压螺杆2包括螺杆轴21和螺杆本体22，螺杆本体22包括具有将物料向下导引的物料推进部221和挤压部222，所述物料推进部221上设有推进螺旋223，所述挤压部222上设有挤压螺旋224，所述压榨腔4套在挤压螺杆2外，电机6通过传动机构(图中未示出)与螺杆轴21动力连接，所述压榨腔4上设有进料口46，进料组件7包括与进料口连通的进料通道71，所述进料通道71包括上端口711和下端口712，所述物料推进部221对应压榨腔4上的进料口46设置，所述进料通道71两端口的几何中心分别为A和B，其连线为AB，AB与竖直平面的夹角为a，0°≤a≤80°。
由于本发明将进料口46及进料通道71设置在压榨腔4上，所述物料推进部221对应进料口46设置，使得物料依靠自身的重力能够很快经进料通道71直接进入压榨腔4内，并在进料口对应位置的物料推进部221的导引作用下快速带入挤压螺旋224与压榨腔4形成的间隙内进行挤压，轻松实现快速自动进料。由于进料通道两端口的中心连线与竖直平面的夹角a的范围为0°≤a≤80°，使得物料和螺杆中心轴成同样的夹角，则在进料通道与竖直面的夹角作用下，物料10依靠自身重力更容易自动进入压榨腔4及进料口46处对应设置的挤压螺杆2的物料推进部221，物料对挤压螺杆冲击力被分解为轴向和水平方向，使得物料10对挤压螺杆2的挤压螺旋224方向的挤压力变小，使得电机扭矩变小，有效降低了电机负载，同时物料被推进螺旋223咬断，并被迅速带入挤压螺旋与压榨腔的间隙，迅速轻松挤压出汁。因此该结构不但进料快速顺畅，而且电机稳定寿命长。
下面将上述快速自动进料的挤压式榨汁机通过具体实施方式详细说明。
实施例一：
作为本发明所述快速自动进料的榨汁机的第一实施例，如图1、图2、图3和图4所示，包括机座1、设置在机座1内的电机6和驱动单元(图中未示出)、挤压螺杆2、与挤压螺杆2配合挤压物料的压榨组件、进料组件7，所述压榨组件安装在机座1上，所述压榨组件包括压榨腔4，压榨腔4上设有出汁口41和出渣口42，所述挤压螺杆2包括螺杆轴21和螺杆本体22，螺杆本体22包括对物料具有向下导引作用的物料推进部221和挤压部222，所述物料推进部221上设有推进螺旋223，所述挤压部222上设有挤压螺旋224，所述压榨腔4套在挤压螺杆2外，压榨腔4包括压榨腔本体43、压榨腔上盖44和压榨腔下盖45，电机6通过传动机构(图中未示出)与螺杆轴21动力连接。所述压榨腔上盖44具有向压榨腔4内部凸出的定位台441，所述定位台441中心设置旋转轴孔4410，所述螺杆轴21上端具有上旋转轴210，所述上旋转轴210可插入 所述旋转轴孔4410内，所述定位台441可对所述挤压螺杆2进行限位。
本实施例中，所述压榨腔本体43为中空的圆柱体，在压榨腔本体43的侧壁上设有进料口46，所述进料口46位于压榨腔本体43的上部，与所述进料口46连接的进料通道71为圆形直管，清洗更方便，所述进料通道71包括上端口711和下端口712，下端口712与压榨腔本体上的进料口46连接，所述进料通道71的内径为45mm，所述进料通道71的两端口的几何中心连线AB与竖直平面的夹角a为60°，此角度保证了物料沿着进料通道向下运动的顺畅，保证了顺利进料。同时所述进料通道的内径为45mm，满足了安规对于口径尺寸的要求，保证了顾客的人身安全。本实施例中的物料推进部221上设有推进螺旋223，所述推进螺旋223沿着挤压螺旋224旋向设置，推进螺旋223的上端对应进料口46设置，下端向下延伸至挤压螺旋224。由于进料通道与竖直平面也即压榨腔本体具有一定的夹角a，因此，在物料自身重力及此夹角的作用下，物料能够快速进入压榨腔本体内，并与推进螺旋223的上部接触，或者直接进入推进螺旋223内，在推进螺旋223的向下导引作用下，先被推进螺旋咬断或者切成小块，同时自动快速向下运动直至进入挤压螺旋和压榨腔的挤压间隙，从而实现了快速榨汁。
如图1和图3所示，所述压榨组件还包括挤压筒3，所述挤压筒3活动设置在压榨腔本体43内，所述挤压筒3为环壁封闭的筒状，挤压筒3内壁上设有与挤压螺旋223配合对物料进行压榨的挤压筋条31，所述挤压筋条31设置为多个，且沿所述挤压筒3轴线中心对称设置。挤压筒活动设置，使得挤压筒的拆卸和清洗变得简便。同时由于设置了挤压筒，压榨腔本体只是起到了集汁的作用，采用挤压筒和挤压螺杆进行挤压出汁，压榨腔本体不直接和挤压螺杆发生作用受力小，因此保证了压榨腔的使用寿命，同时由于挤压筋条设置在挤压筒上，则保证了压榨腔的清洗更容易。
不设过滤网的挤压筒与挤压螺杆配合可以制作含颗粒或者果粒的果汁或者冰激凌等。而当用来挤压坚果类物料比如核桃、花生等物料与水 果混合制作内含坚果颗粒的果汁时，将坚果或者小块水果从进料通道盖上端口71加入，同时调节挤压间隙大一些，可以不必停机直接压榨，能够压榨出满足颗粒感的坚果颗粒，由于未设置过滤网，故果渣从出渣口挤出，而后将榨出的核桃颗粒、花生颗粒等放入挤压出的果汁杯内，方便制作含颗粒的混合饮料。由于挤压筒上未设过滤部，此种结构更适合制作果泥、果泥果粒混合物、蔬菜泥、冰激凌等及坚果类食品的混合物。
当然，该榨汁机的挤压筒也可以和压榨腔合为一体结构，即在压榨腔本体内壁上设置挤压筋条，在压榨腔本体的侧壁上设置出汁口，在出汁口设置过滤网，在压榨腔下盖上设置出渣口。此种结构虽然过滤效果及压榨腔的清洗难易程度较前述方案差一点，但是该种方案减少了一个配件，减少了一个拆卸和清洗步骤。这种不脱离本实施例的简单结构变化，也在本发明的保护范围内，这里不再一一举例。
如图2所示，所述压榨腔本体43的内径为45mm，所述压榨腔本体43包括上口431和下口432，所述压榨腔本体的上口431处设有压榨腔上盖44，下口432处设有压榨腔下盖45，所述压榨腔上盖44和压榨腔下盖45分别活动安装于压榨腔本体43的上口431和下口432处，本实施例中，所述压榨腔上盖44和压榨腔下盖45分别是通过螺纹连接方式活动安装在压榨腔本体43的上口431和下口432上的。由于压榨腔上盖44和压榨腔下盖45分别活动安装于压榨腔本体上，方便了挤压螺杆的拆卸，也方便了压榨腔及挤压螺杆的清洗，使得清洗更彻底。所述出渣口42设置在所述压榨腔下盖45的底部，所述压榨腔下盖45上设有排汁通道451，所述出汁口41设置在压榨腔本体43的下端，排汁通道451与出汁口41连通，使得出汁更顺畅。
当然，本实施例的进料通道也可以设置成圆形弯管或者椭圆形直管等形状；这种不脱离本发明实质的管道形状的改变，也在本发明的保护范围内。
实施例二：
作为本发明所述的快速自动进料的榨汁机的第二实施例，如图5和 图6所示，包括机座1、设置在机座1内的电机6和驱动单元(图中未示出)、挤压螺杆2、与挤压螺杆2配合挤压物料的压榨组件、进料组件7，所述压榨组件安装在机座1上，所述压榨组件包括压榨腔4，压榨腔4上设有出汁口(图中未示出)和出渣口(图中未示出)，所述挤压螺杆2包括螺杆轴21和螺杆本体22，螺杆本体22包括将物料向下导引的物料推进部221和挤压部222，所述物料推进部221上设有推进螺旋223，所述挤压部222上设有挤压螺旋224，所述压榨腔4套在挤压螺杆2外，压榨腔4包括压榨腔本体43、压榨腔上盖44和压榨腔下盖45，电机6通过传动机构(图中未示出)与螺杆轴21动力连接。
如图5和图6所示，所述压榨组件还包括挤压筒3和过滤部5，所述过滤部5为设置在挤压筒上的过滤网孔51，所述过滤部5在挤压筒上间隔设置，过滤网孔51分布在挤压筋条31所在区域的上部和下部。这样不但保证了挤压筒的强度，同时也方便了挤出的汁及时从挤压筒内流出。所述挤压筒3设置在压榨腔本体43内，挤压筒3内壁上设有与挤压螺旋224配合的挤压筋条31。所述压榨腔本体43的侧壁上设有进料口46，与进料口46连通的进料通道71为圆形直管，所述进料通道的两端口的几何中心分别为A和B，其连线为AB，AB与竖直平面的夹角a为30°，此角度进料效果较好。推进螺旋223的上端对应进料口46设置，下端向下延伸至挤压螺旋224。所述进料通道的内径为80mm，实现了大口径进料，使得苹果、西红柿等圆形物料不必切成小块，直接整个或者最多切为两半就可放入进料通道内，而黄瓜等长形物料直接放入进料通道内，物料顺着该进料通道的斜度，轻松进入压榨腔本体，并进入推进螺旋223内或者与所述推进螺旋223接触。保证了只要电机一启动，与推进螺旋223接触的物料(整个物料或者大块物料)迅速被推进螺旋咬断并进入推进螺旋内，而进入推进螺旋内的物料或者被咬断的物料能够在压榨腔本体和推进螺旋的共同作用下挤压成小块，随后被推进螺旋快速输送至挤压螺旋224和挤压筒3的间隙内进行挤压，在挤压筒3上设置的挤压筋条31和挤压螺旋224的挤压下，物料被挤碎，汁从挤压筒3 的过滤网孔51流出，并顺着压榨腔本体和挤压筒的间隙向下流动从出汁口排出，而渣则留在了挤压筒内继续向下被推进，从出渣口排出，实现了渣汁分离。
如图5所示，所述进料通道71包括上端口711和下端口712，下端口712与压榨腔本体上的进料口46连接，上端口711设有进料通道盖72，本实施例的进料通道盖72呈打开状态，进料通道盖72铰接于进料通道71的上端口711上。由于本实施例为进料通道为大口径，故为满足安全要求我们在进料通道上设置了进料通道盖72，并设置了安全机构，保证在进料通道盖72打开的状态，电机不工作，保证了顾客的人身安全。
如图5所示，本实施例中压榨腔和实施例一中的压榨腔的区别是：所述压榨腔上盖44活动安装于压榨腔本体43的上口431，所述压榨腔下盖45和压榨腔本体43为一体制成。本实施例中，所述压榨腔本体43为上宽下窄的倒圆台形，其锥度为10°，所述压榨腔下盖45通过超声波焊接在压榨腔本体43的下口432上，所述压榨腔上盖44通过螺纹铰接结构设置在压榨腔本体43的上口431上。由于挤压腔本体为上宽下窄的倒圆台形，不但保证了挤压螺杆2和挤压筒3方便地从压榨腔本体43的上口431安装与取出，也方便了压榨腔及其内部配件的清洗。同时所述压榨腔本体43形状与进料通道71倾斜角度的结合，使得进入压榨腔的物料在压榨腔本体斜面的导引下，继续向下运动，更从容的滑入进料口对应位置的推进螺旋内，进料更加顺畅。所述压榨腔的其余结构均和图2所示的实施例一中的压榨腔结构及其产生的有益效果一致，这里不再一一赘述。
当然，由于压榨腔本体43呈上宽下窄的倒圆台形，故也可以在压榨腔上盖44上设置辅助进料口。这种结构的简单变换也在本发明的保护范围内，这里不再一一举例。
实施例三：
如图7所示，作为本发明所述的快速自动进料榨汁机的第三实施例，与实施例二的区别是：所述进料通道71的两端口的几何中心分别为A 和B，其连线为AB，AB与竖直平面的夹角a为55°，所述进料通道的内径为70mm。此进料通道的斜度及直径大小，使得进料效果较佳。所述榨汁机还设有辅助进料口73，所述辅助进料口73设置在进料通道盖72上。通过在进料通道盖上设置辅助进料口，方便已经切成小块的物料或者较小物料比如红果、葡萄、杏等的加入，可以不必开盖停机。对于制作不同大小物料的混合果汁，非常方便实用。
如图7所示，所述压榨腔上盖44与压榨腔本体43合为一体结构，所述压榨腔下盖45活动安装在压榨腔本体43上，本实施例中，所述压榨腔本体43的上部纵截面为上窄下宽的圆台形，下部纵截面为圆柱形。所述压榨腔上盖45与压榨腔本体43是注塑为一体结构的，所述压榨腔下盖45是通过卡扣结构活动安装于压榨腔本体43的下口432上的。此压榨腔本体43呈下窄上宽的圆台形状，且压榨腔下盖45和压榨腔本体43为活动安装，保证了位于其内的挤压螺杆2及挤压筒3从压榨腔本体的下口取出清洗，方便了配件的清洗。同时该压榨腔本体的形状和进料通道的角度结合，使得物料进入挤压腔内后，受压榨腔斜面的向下作用，物料更方便进入对应于进料口46处的推进螺旋223内，物料更容易被推进至挤压螺旋224和挤压筒3的间隙内被压榨。
如图8所示，所述榨汁机的挤压筒3外还套设有旋转壁刷组件8，所述旋转壁刷组件8包括壁刷架81和设置壁刷架上的软性壁刷82，壁刷架81通过传动装置(图中未示出)与电机6连接，所述挤压筒3套设在旋转壁刷架81内，软性壁刷82与过滤网孔51线接触或者面接触。软性壁刷82不断从过滤网孔51上扫过，破坏了液体和过滤网孔51的表面张力作用，使得果汁流出更顺畅，使得网孔不会被西红柿等软性水果的果汁堵住。
本实施例的其余结构及其有益效果均和实施例二一致，这里不再一一赘述。
当然，本实施例中的物料推进部221也可以采用沿着挤压螺旋方向设置的筋条，或者将物料推进部221设置为沿着挤压螺旋旋向设置的粗 切刀，都可以满足快速进料的要求，这种不脱离本发明实质的简单结构变形，都在本发明的保护范围内，这里不再一一举例。
实施例四：
如图9和10所示，作为本发明所述的快速自动进料榨汁机的第四实施例，与实施例三的区别是：所述压榨腔本体43的上部为中空的圆台形，下部为中空的圆柱形，所述进料口46设置在压榨腔本体43的锥面上，所述进料通道71的两端口的几何中心分别为A和B，其连线为AB，AB与竖直平面的夹角a为0°，所述进料通道71的内径为60mm。如图10所示，本实施例中所述过滤部5为设置在挤压筒3的挤压筋条31区域上部的过滤网孔51和设置在挤压筒3的挤压筋条31下部的过滤网栅条52，所述过滤栅条52为圆环形，且呈波浪起伏状。采用过滤栅条，相邻2个过滤栅条间设有过滤间隙，汁液从过滤间隙中流出，渣留在了过滤栅条内，并从压榨腔下盖上的出渣口排出，方便了挤压筒的清洗。本实施例的其余结构及其有益效果均和实施例三一致，这里不再一一赘述。
实施例五：
如图11所示，作为本发明所述的快速自动进料榨汁机的第五实施例，与实施例二的区别是：所述进料通道71的两端口的几何中心分别为A和B，其连线为AB，AB与竖直平面的夹角a为80°，所述进料通道的直径为35mm。所述进料通道也为上端口小下端口大的中空的圆台形。该进料通道71和压榨腔4的夹角为35°，配合压榨腔4的形状，方便了物料的快速自动进入。本实施例的其余结构及其有益效果均和实施例二一致，这里不再一一赘述。
实施例六：
如图12、13所示，作为本发明所述的快速自动进料榨汁机的第六实施例，包括机座1、设置于机座内的电机(图中未示出)、挤压螺杆2、与挤压螺杆2配合挤压物料的压榨组件，所述压榨组件包括压榨腔4、挤压筒3、过滤部5及旋转刷组件8，所述压榨腔4安装于机座1上，所述挤压筒3套设于所述挤压螺杆2外部，所述旋转刷组件8套设于所述 挤压筒3外部，并用于清洗所述过滤部5，所述挤压螺杆2、挤压筒3及旋转刷组件8同心且插入所述压榨腔4内，所述压榨腔4包括压榨腔本体43及压榨腔上盖44，所述挤压螺杆2安装于压榨腔4内，所述挤压螺杆2包括物料推进部221和挤压部222，所述压榨腔上盖44设有内部向上凸出并用于容纳所述挤压螺杆2上部的容纳部440，所述容纳部440的侧壁设有进料口46及与所述进料口46连接的进料通道71，所述物料推进部221对应所述容纳部440的进料口46设置。容纳部440的设置，增大了物料的容纳空间，物料通过进料通道71后在重力的作用下进入容纳部440，保证有充足的物料在容纳部440中与挤压螺杆2的物料推进部221配合进行初步粉碎，由于容纳部440的容纳空间是在重力方向设置的，方便了物料的输送，使得进料更方便、顺畅且阻力小。由于挤压螺杆2包括物料推进部221和挤压部222，将挤压螺杆2一部分置于压榨腔上盖的容纳部440中，一部分置于压榨腔本体43中，使得榨汁机的结构更加合理，方便挤压螺杆2、压榨腔上盖44以及压榨腔本体43的安装、拆卸清洗。所述压榨腔本体43和所述压榨腔上盖44的容纳部440共同用于容纳挤压螺杆2，使得压榨腔本体43和容纳部440的深度不会过深，不易产生清洗死角，达到榨汁机易清洗的目的。
所述容纳部440的侧壁设有进料口46及与进料口46连接的进料通道71，所述进料通道71包括上端口711和下端口712，所述下端口712与所述进料口46连接，所述进料通道71的两端口的几何中心分别为A和B，其连线为AB，AB与竖直平面的夹角为a，30°≤a≤60°。本实施例中，a＝45°，此时物料最易快速通过进料通道71并正好切入推进螺旋223进行预粉碎且粉碎效果好。
而物料和挤压螺杆2的中心轴成同样的夹角，相当于斜向放料，使得物料依靠自身的重力能够很快经进料通道71直接进入容纳部440内，并在进料口46对应位置的物料推进部221的向下导引作用下快速被带入挤压螺杆2的挤压部222与压榨腔4形成的榨汁间隙内进行挤压，轻松实现快速自动进料。同时，倾斜设置的进料通道71相对于竖直放置的管 道变长，有效防止人的手伸入进料通道过深，使得榨汁机的安全性更高，且结构简单，易加工成型。
物料在自身重力及夹角a的作用下，快速落入下端口712并切入推进螺旋223内，实现快速高效的初步粉碎，进而由推进螺旋223向下旋转将经过初步粉碎的物料快速带入挤压部222与压榨腔4形成的间隙内进行二次粉碎及挤压榨汁，提高榨汁机的出汁效率及出汁率。同时不仅使榨汁机的整体外观造型达到最优化，而且使得物料经过进料通道71的下端口进入物料推进部221时对挤压螺杆2的冲击力在轴向和水平方向分解后减小了对压榨腔上盖的损耗，也使得物料对挤压螺杆的螺旋方向的挤压力变小，使得电机扭矩变小，有效降低了电机负载，不但进料更顺畅，而且电机更稳定，寿命长。
所述物料推进部221用于将物料向下导引，所述物料推进部221对应容纳部440的进料口设置，使得物料依靠自身重力及在进料通道与竖直面的夹角作用下，进入到所述压榨腔上盖44的容纳部440，位于容纳部440中的挤压螺杆2的物料推进部221将物料向下导引。
所述物料推进部221还包括设于所述螺杆本体22上的推进螺旋223，位于所述物料推进部221的所述螺杆本体22呈圆柱形，使物料更容易被引入到所述挤压螺杆2的物料推进部221，进行物料的预粉碎且粉碎效果好，物料被所述推进螺旋223咬断并在其作用下，被快速带入挤压部222与所述挤压筒3形成的间隙内进行挤压榨汁，实现快速自动进料并使得物料被挤压出汁，提高了榨汁机的出汁效率和出汁率。所述进料通道71呈直圆筒形，使对应的所述进料口46横截面的等效直径达到最大，能够适应不同大小的物料，同时物料更容易沿所述进料通道71内壁进入所述容纳部440进行压榨。另外，所述螺杆本体22上端呈圆柱形，对应的容纳部440呈直筒形，并且挤压螺杆2的物料推进部221与容纳部440之间设置一定的间隙，所述挤压螺杆2在转动的过程中不会与所述容纳部440内壁发生摩擦，所述容纳部440内壁设有压榨筋条，压榨筋条对物料的初步粉碎起到阻挡作用，使得物料被转动的挤压螺杆 2带入推进螺旋223进行初步粉碎时不会在容纳部440内打转，而是在压榨筋条的阻挡作用下沿推进螺旋223被咬断，进而由推进螺旋223向下旋转将经过初步粉碎的物料快速带入挤压部222与所述挤压筒3形成的间隙内进行二次粉碎及挤压榨汁。容纳部440的高度与容纳部440的等效直径的比值为4/5至13/5，当比值小于4/5时，在满足整机外观结构及造型的前提下没有足够的空间容纳物料推进部221，当比值大于13/5时，物料通过进料通道进入物料推进部221时，不利于物料的咬入和初步粉碎，所述推进螺旋223不能快速有效的将物料咬断并向下推送挤压。本实施例中，所述容纳部440的高度与等效直径的比值为32/23，所述容纳部的高度为64mm，容纳部的等效直径为46mm，保证能够容纳挤压螺杆2和向下推进的物料，实现快速挤压出汁，提高了榨汁机的出汁效率，
所述进料口46的等效直径与容纳部的等效直径的比值为2/3至4/3，所述进料口46的等效直径范围为40mm～45mm，所述容纳部440的等效直径范围为41-46mm，当进料口46的等效直径小于40mm时，虽然满足安规要求但进料口过小，需要将果蔬切成很小的块状才能通过进料通道进行榨汁，不方便用户操作，也降低了榨汁效率。当进料口46的等效直径大于45mm时，则需要增设安全保护措施才能实现大口径进料。本实施例中，所述进料口的等效直径与容纳部的等效直径的比值为45/46。所述进料口的等效直径为45mm，相应的，所述进料通道的上端口的直径也为45mm，所述容纳部440的等效直径为46mm，这样不仅满足安规标准要求，而且可以实现快速进料。用户在使用榨汁机时，由于进料口径的限制，手指不会碰到转动的挤压螺杆2，从而避免机械危险的发生，保证了用户使用榨汁机的安全。
所述挤压螺杆2的上端还设有与容纳部440顶壁配合的顶端面，所述顶端面上设有上旋转轴210，所述容纳部440的内顶壁中心处设有旋转塞4400，所述旋转塞4400设有用于容纳所述上旋转轴210的旋转轴孔4401，装配好挤压螺杆2后，所述上旋转轴210插入到所述旋转轴孔 4401中，与所述旋转轴孔4401在径向上间隙配合，在榨汁机工作过程中对转动的挤压螺杆2进行径向限位，防止所述挤压螺杆2在压榨过程中发生径向的摆动。
所述螺杆轴21的上端凸出于所述挤压螺杆2的上端面，使得所述上旋转轴210与所述挤压螺杆2之间形成旋转轴定位台阶211，所述挤压螺杆2通过所述旋转轴定位台阶211与所述容纳部440的内顶壁配合，在榨汁机工作过程中对转动的挤压螺杆2进行轴向限位，挤压螺杆2沿推进螺旋223的螺旋方向对物料产生向下的作用力，同时受到物料对挤压螺杆2的向上的反作用力，此时挤压螺杆2通过顶端面与容纳部440顶壁配合对挤压螺杆2进行轴向限位，防止挤压螺杆因受到物料向上的作用力而发生轴向移动，保证挤压部222与压榨腔之间形成有效的粉碎间隙对物料实现挤压出汁，同时避免了经压榨后的果蔬渣进入挤压螺杆2底部发生堵渣现象，也避免了果蔬渣将挤压螺杆向上顶起，进而对压榨腔上盖形成保护，避免应力集中而损坏压榨腔上盖，延长了榨汁机的使用寿命。另外，所述旋转轴定位台阶的设置减小了挤压螺杆2与容纳部顶壁的接触面积，从而有效减小了挤压螺杆与容纳部之间的摩擦力，减小了榨汁过程中对挤压螺杆和压榨腔上盖的磨损。同时，所述螺杆轴21材质为金属，优选为不锈钢，使得螺杆轴与容纳部440之间的摩擦力减小，且不易磨损。
所述压榨腔上盖44下端与压榨腔本体43上端配合，所述压榨腔本体43上端内侧壁设有卡扣，所述压榨腔上盖44的下端向下延伸形成环形围边，所述环形围边的侧壁设有卡槽，所述卡扣旋入卡槽中，使压榨腔上盖44固定于压榨腔上。压榨腔上盖44与压榨腔本体43通过卡扣旋入卡槽中配合，使压榨腔上盖44与压榨腔本体43连接稳定、可靠，且易于拆装和清洗。压榨腔上盖44的下端向下延伸形成环形围边，所述环形围边的设置增加了压榨腔上盖44与压榨腔本体43的配合面积，防止压榨腔、压榨腔上盖在与挤压螺杆配合进行挤压粉碎物料时发生径向的摆动，同时也减小了榨汁机工作过程中整机的晃动，使压榨腔上盖44 和压榨腔本体43的连接更加可靠，榨汁部件的使用寿命更长。
可以理解的，所述夹角a的取值可以为35°、40°、50°、55°、60°。
可以理解的，所述进料口的等效直径的取值可以为40mm、41mm、42mm、43mm、44mm，容纳部的等效直径为41mm、42mm、43mm、44mm、45mm。
可以理解的，如图14所示，所述挤压螺杆本体呈上小下大的圆台形。
可以理解的，所述进料通道为弯圆管或直椭圆管或弯椭圆管。
可以理解的，所述容纳部的顶壁中心处设有上旋转轴，所述挤压螺杆上端设有用于容纳所述上旋转轴的旋转轴孔。
实施例七：
如图15所示，本实施例与实施例六的区别在于，所述进料通道71包括连接段713和进料段714，所述连接段713与进料段714均为直圆筒形。所述连接段713的中心线与竖直平面的夹角为a，30°≤a≤60°，所述连接段713的一端与进料口46连接，另一端与进料段714光滑连接。所述进料段714竖直设置，进料段714的上端口711用于投放物料，另一端则与连接段713光滑连接。
所述进料段714竖直设置，使得进料段714的上端口711处于水平位置，这样从竖直方向进行投料，更能够适应用户的操作习惯，且落料迅速顺畅。所述进料段714与连接段713光滑连接，这样，用户在投入物料时，物料通过竖直的进料段714后顺利进入连接段713，不易卡料，且进料段714与连接段713光滑连接也使榨汁机外形更美观。物料沿着进料通道71的连接段713顺利通过进料口46进入物料推进部221，并被推进螺旋223快速向下带入挤压部222与压榨腔4形成的间隙内进行挤压榨汁，提高了榨汁效率。
所述连接段713的中心线与竖直平面的夹角为a，30°≤a≤60°，当a小于30°时，虽然能实现快速落料，但物料到达下端口时与挤压螺杆2的中心距离较近，挤压螺杆2的转速较小，承受的扭矩较大，不利于物料的咬入和预粉碎。当a大于60°时，进料通道71的连接段713 过于平缓，物料连接段内壁的摩擦力较大，物料容易卡在进料段714与连接段713的接合处，不利于快速进料，降低了榨汁效率。本实施例中，a＝45°，此时物料最易快速通过连接段并正好切入推进螺旋223进行预粉碎且粉碎效果好。
实施例八：
本实施例与实施例六的区别在于，所述进料通道包括连接段和进料段，所述连接段与进料段均为直圆筒形。所述连接段的中心线与竖直平面的夹角为a，30°≤a≤60°，所述连接段的一端与进料口连接，另一端与进料段光滑连接。所述进料段竖直设置，进料段的上端口用于投放物料，另一端则与连接段光滑连接。
所述进料段竖直设置，使得进料段的上端口处于水平位置，这样从竖直方向进行投料，更能够适应用户的操作习惯，且落料迅速顺畅。所述进料段与连接段光滑连接，这样，用户在投入物料时，物料通过竖直的进料段后顺利进入连接段，不易卡料，且进料段与连接段光滑连接也使榨汁机外形更美观。物料沿着进料通道的连接段顺利通过进料口进入物料推进部，并被推进螺旋快速向下带入挤压部与压榨腔形成的间隙内进行挤压榨汁，提高了榨汁效率。
所述连接段的中心线与竖直平面的夹角为a，30°≤a≤60°，当a小于30°时，虽然能实现快速落料，但物料到达下端口时与挤压螺杆的中心距离较近，挤压螺杆的转速较小，承受的扭矩较大，不利于物料的咬入和预粉碎。当a大于60°时，进料通道的连接段过于平缓，物料连接段内壁的摩擦力较大，物料容易卡在进料段与连接段的接合处，不利于快速进料，降低了榨汁效率。本实施例中，a＝45°，此时物料最易快速通过连接段并正好切入推进螺旋进行预粉碎且粉碎效果好。
所述进料口的等效直径范围为40mm～45mm，所述容纳部呈直筒形，所述容纳部的等效直径范围为41-46mm，当进料口的等效直径小于40mm时，虽然满足安规要求但进料口过小，需要将果蔬切成很小的块状才能通过进料通道进行榨汁，不方便用户操作，也降低了榨汁效率。当进料 口的等效直径大于45mm时，则需要增设安全保护措施才能实现大口径进料。本实施例中，所述进料口的等效直径为45mm，相应的，所述进料通道的上端口的直径也为45mm，所述容纳部的等效直径为46mm，这样不仅满足安规标准要求，而且可以实现快速进料。用户在使用榨汁机时，由于进料口径的限制，手指不会碰到转动的挤压螺杆，从而避免机械危险的发生，保证了用户使用榨汁机的安全。
可以理解的，所述容纳部呈上小下大的锥筒形。
实施例九：
本实施例与实施例六的区别在于，所述容纳部呈上小下大的锥筒形，使挤压螺杆的物料推进部与容纳部之间形成一定的间隙，挤压螺杆在转动的过程中不会与容纳部内壁发生摩擦。同时，容纳部呈上小下大的锥筒形，使得物料有充足的容纳空间，且容纳空间在重力方向上设置，更有利于物料的容纳和下料，当物料进入物料推进部后，容纳部内壁设有压榨筋条，压榨筋条对物料的初步粉碎起到阻挡作用，使得物料被转动的挤压螺杆带入推进螺旋进行初步粉碎时不会在容纳部内打转，而是在压榨筋条的阻挡作用下沿推进螺旋被咬断，进而由推进螺旋向下旋转将经过初步粉碎的物料快速带入挤压部与压榨腔形成的间隙内进行二次粉碎及挤压榨汁。
实施例十：
作为本发明所述快速自动进料的榨汁机的第十实施例，如图16所示，包括机座1、设置在机座内的电机(图中未示出)、挤压螺杆2、与挤压螺杆2配合挤压物料的压榨组件、进料组件7，所述压榨腔安装在机座上，所述压榨组件包括压榨腔4，所述压榨腔4上设有出汁口和出渣口，所述挤压螺杆2安装于压榨腔内，所述挤压螺杆2包括物料推进部221和挤压部222，其中，所述压榨腔4包括容纳物料推进部的上压榨腔47和容纳挤压研磨部的下压榨腔48，所述上压榨腔47和下压榨腔48可拆卸连接，所述上压榨腔47包括上压榨腔本体470和压榨腔上盖471，所述进料口46的等效直径与上压榨腔本体470的等效直径的比值 为2/3至4/3，这样不仅可以使进料口足够大以实现用户整果榨汁的需求，同时使得进料通道与上压榨腔本体的接合部位形成的下端口正好对应挤压螺杆的推进螺旋。当进料口的等效直径过小时，不能充分满足整果榨汁的需求，当进料口的等效直径过大时，物料经过下端口后容易卡在上压榨腔本体内，无法进入推进螺旋进行榨汁，而且进料通道的直径过大影响榨汁机的整体外观造型。
所述上压榨腔47和下压榨腔48可拆卸连接，这样设置的好处在于，榨汁机的结构更加合理，方便挤压螺杆2、上压榨腔47以及下压榨腔48的拆装和清洗。上压榨腔47和下压榨腔48共同用于容纳挤压螺杆2，使得上压榨腔47和下压榨腔48的深度不会过深，不易产生清洗死角，达到榨汁机易清洗的目的。用户在组装榨汁机时，将挤压螺杆2置于下压榨腔48内，由于下压榨腔48的高度低于挤压螺杆2，使得挤压螺杆2可轻松装入下压榨腔48中，而上压榨腔47不仅可以封闭下压榨腔48的上端口，将挤压螺杆2与外界隔开，保证了用户使用榨汁机的安全，同时可以容纳挤压螺杆的物料推进部221，增大了物料的容纳空间，物料通过进料通道后在重力的作用下进入上压榨腔本体470，保证有充足的物料在上压榨腔本体470中与挤压螺杆2的物料推进部221配合进行初步粉碎，由于上压榨腔47的容纳空间是在重力方向设置的，方便了物料的输送，使得进料更方便、顺畅且阻力小。
由于将进料口46及进料通道71设置在上压榨腔本体470的侧壁，进料通道71两端口的几何中心的连线与竖直平面的夹角a满足30°≤a≤60°，使得物料和挤压螺杆2中心轴成同样的夹角，相当于斜向放料，使得物料依靠自身的重力能够很快经进料通道71直接进入上压榨腔本体470内，并在进料口46对应位置的物料推进部221的向下导引作用下快速被带入挤压螺杆2的挤压部222与下压榨腔48形成的榨汁间隙内进行挤压，轻松实现快速自动进料。当a小于30°时，虽然能实现快速落料，但物料到达下端口时与挤压螺杆2的中心距离较近，挤压螺杆2的转速较小，承受的扭矩较大，不利于物料的咬入和初步粉碎。当a大 于60°时，进料通道过于平缓，物料与进料通道71的摩擦力较大，不利于快速进料，降低了榨汁效率。同时，倾斜设置的进料通道71相对于竖直放置的管道变长，有效防止人的手伸入进料通道过深，使得榨汁机的安全性更高，且结构简单，易加工成型。本实施例中，a＝45°，此时物料最易快速通过进料通道71并正好切入推进螺旋进行初步粉碎且粉碎效果好。
另外，由于进料口46设置在上压榨腔本体470的侧壁上，则进料口径的大小及位置不必受挤压螺杆2及上压榨腔47直径尺寸的影响，可以轻松实现大口径入料，当采用大口径时，由于进料通道71两端口的几何中心的连线与竖直平面成夹角a，物料对挤压螺杆2的冲击力被分解为轴向和水平方向，因此，物料对挤压螺杆2的螺旋方向的挤压力变小，使得电机扭矩变小，有效降低了电机负载，不但进料更顺畅，而且电机稳定，寿命长。
挤压螺杆2的物料推进部221将物料向下导引，物料推进部221是设置在挤压螺杆本体上的推进螺旋223，推进螺旋223将物料咬断进行初步粉碎后沿推进螺旋223将物料快速带入挤压部222与下压榨腔48形成的间隙内进行挤压榨汁。推进螺旋223的螺距与进料口的等效直径的比值为1/2至3/2，当推进螺旋223的螺距与进料口的等效直径比值小于1/2时，物料通过进料通道后不能够顺利进入推进螺旋，而且螺距相对较小使得物料无法被快速带入到挤压部222，影响榨汁效率。当比值大于3/2时，物料相对于螺距较小，物料不易被咬断，不能达到预粉碎的目的。本实施例中，推进螺旋的螺距与进料口的等效直径的比值为1/1，推进螺旋223的螺距为45mm，进料口的等效直径为45mm，此时，当物料通过进料通道后能够顺利进入推进螺旋223，被推进螺旋223咬断并沿推进螺旋向下被带入挤压部222与下压榨腔48形成的间隙内进行挤压榨汁，实现快速榨汁。
所述进料通道71呈直圆筒形，使对应的进料口横截面达到最大，能够适应不同大小的物料，实现大口径进料，同时物料更容易沿进料通道 71内壁进入上压榨腔本体470进行压榨。所述螺杆本体22呈圆柱形或上小下大的圆台形，使物料更容易被引入到挤压螺杆的物料推进部，对物料进行初步粉碎且粉碎效果好。所述物料推进部与挤压研磨部过渡连接，所述推进螺旋由螺杆本体22上端延伸至挤压部222下端，使得榨汁机的进料更顺畅，物料被推进螺旋223咬断并在其作用下，被快速带入挤压部222与下压榨腔形成的间隙内进行挤压榨汁，实现快速自动进料并使得物料被挤压出汁，提高了榨汁机的出汁效率和出汁率。
所述进料口46的等效直径范围为40mm～45mm，所述上压榨腔本体470的等效直径范围为41-46mm，当进料口46的等效直径小于40mm时，虽然满足安规要求但进料口过小，需要将果蔬切成很小的块状才能通过进料通道71进行榨汁，不方便用户操作，也降低了榨汁效率。当进料口46的等效直径大于45mm时，则需要增设安全保护措施才能实现大口径进料。本实施例中，所述进料口46的等效直径与上压榨腔本体470的等效直径的比值为45/46。所述进料口46的等效直径为45mm，相应的，所述进料通道的上端口的直径也为45mm，所述上压榨腔本体470的等效直径为46mm，这样不仅满足安规标准要求，而且可以实现快速进料。用户在使用榨汁机时，由于进料口径的限制，手指不会碰到转动的挤压螺杆2，从而避免机械危险的发生，保证了用户使用榨汁机的安全。
同时，物料在自身重力及夹角a的作用下，快速落入下端口并切入推进螺旋内，实现快速高效的初步粉碎，进而由推进螺旋223向下旋转将经过初步粉碎的物料快速带入挤压部222与下压榨腔48形成的间隙内进行粉碎及挤压榨汁，提高榨汁机的出汁效率及出汁率。不仅使榨汁机的整体外观造型达到最优化，而且使得物料经过进料通道的下端口进入物料推进部时对挤压螺杆的冲击力在轴向和水平方向分解后的大小达到最优，减小了对压榨腔的损耗，也使得物料对挤压螺杆的螺旋方向的挤压力变小，使得电机扭矩变小，有效降低了电机负载，不但进料更顺畅，而且电机更稳定，寿命长。
所述上压榨腔47的下端设有环形围边，所述环形围边的侧壁设有卡 槽，所述下压榨腔48的上端内侧壁设有卡扣，所述卡扣旋入卡槽中，使上压榨腔47与下压榨腔48连接稳定、可靠，且易于拆装和清洗。上压榨腔47的下端设有环形围边，所述环形围边的设置增加了上压榨腔与下压榨腔的配合面积，防止上压榨腔47、下压榨腔48在与挤压螺杆2配合进行粉碎物料和挤压榨汁时发生径向摆动，同时也减小了榨汁机工作过程中整机的晃动，使上压榨腔47和下压榨腔48的连接更加可靠，榨汁部件的使用寿命更长。
所述挤压螺杆2的上端还设有与上压榨腔本体470顶壁配合的顶端面，所述顶端面上设有上旋转轴43，所述上压榨腔本体470的顶壁中心处设有用于容纳所述上旋转轴的旋转轴孔24，装配好挤压螺杆2后，上旋转轴43插入到旋转轴孔24中与旋转轴孔在径向上间隙配合，在榨汁机工作过程中对转动的挤压螺杆2进行径向限位，防止挤压螺杆2在压榨过程中发生径向的摆动。
所述挤压螺杆2的顶端面与上压榨腔本体470的顶壁配合，在榨汁机工作过程中对转动的挤压螺杆2进行轴向限位，挤压螺杆2沿推进螺旋223的螺旋方向对物料产生向下的作用力，同时受到物料对挤压螺杆2的向上的反作用力，此时挤压螺杆2通过顶端面与上压榨腔本体470顶壁配合对挤压螺杆2进行轴向限位，防止挤压螺杆因受到物料向上的作用力而发生轴向移动，保证挤压部222与压榨腔之间形成有效的粉碎间隙对物料实现挤压出汁，同时避免了经压榨后的果蔬渣进入挤压螺杆2底部发生堵渣现象，也避免了果蔬渣将挤压螺杆向上顶起，进而对上压榨腔形成保护，避免应力集中而损坏上压榨腔，延长了榨汁机的使用寿命。另外，顶端面的设置减小了挤压螺杆2与上压榨腔本体470顶壁的接触面积，从而有效减小了挤压螺杆与上压榨腔本体之间的摩擦力，减小了榨汁过程中对挤压螺杆和上压榨腔的磨损。
可以理解的，所述夹角a的取值可以为35°、40°、50°、55°、60°。
可以理解的，所述挤压螺杆本体呈上小下大的圆台形。
可以理解的，所述进料通道为直圆筒或弯圆管或直椭圆管或弯椭圆管。
可以理解的，所述上压榨腔本体的顶壁中心处设有上旋转轴，所述挤压螺杆上端设有用于容纳所述上旋转轴的旋转轴孔。
以上所述者，仅为本发明的较佳实施例而已，并非用来限定本发明的实施范围，即凡依本发明所作的均等变化与修饰，皆为本发明权利要求范围所涵盖，这里不再一一举例。
