参照图1和图4所示，本发明一种实施例的研磨组件，应用于破壁机等料理设备，通过研磨件100对食物进行切割、粉碎或研磨处理，从而打破食物中细胞的细胞壁，将细胞中的维生素、矿物质、植化素、蛋白质和水分等充分释放出来，从而获得颗粒尺寸较小的食物，实现对食物的料理加工。本发明一种实施例的研磨组件，包括研磨件100，研磨件100的中心通过驱动轴400与驱动电机(图中未示出)连接。
参照图4所示，本发明一种实施例的研磨组件，还包括底盘200，底盘200一般与料理机的搅拌杯(图中未示出)固定连接，研磨件100相对转动于底盘200的上方。参照图5所示，底盘200具有第一研磨部210，参照图7所示，研磨件100具有第二研磨部110，第二研磨部110与第一研磨部210相配合以实现研磨。参照图2所示，当驱动电机驱动研磨件100与底盘200相对转动的过程中，食物流体被引流至第一研磨部210和第二研磨部110之间形成的研磨通道300，第一研磨部210与第二研磨部110共同作用于食物上，实现对食物的精细研磨。由于采用研磨件100和底盘200配合实现研磨，因此能够在较低转速下达到较好的研磨性能，从而可以降低搅打的速度，降低驱动电机的转速，从而降低工作噪音，提升用户体验。
参照图2和图3所示，研磨件100具有研磨通道300的进口310，研磨件100的外周沿和底盘200之间形成有研磨通道300的出口320，因此食物流体在料理机的上刀500的作用下，通过进口310进入研磨通道300，在上刀500的离心力作用下，食物流体通过研磨通道300进行研磨后从出口320排出，排出后的食物流体在上刀500的作用下可以循环回流至出口320，从而实现循环研磨，使得食物研磨更加细腻，研磨效果更佳。
参照图2所示，在本发明的一些实施例中，第一研磨部210设于底盘200的底面，第二研磨部110设于研磨件100的下端面，食物流体通过研磨通道300时受到上下方向上的研磨作用力。沿远离底盘200中心的 方向，研磨通道300在上下方向的间隙a逐渐减小，间隙a逐渐减小可以使食物在离心力的作用下沿底盘200的中心向四周流动的过程中，逐步实现粗磨、半精磨到精磨的过程，使得食物流体逐步进行细化研磨，进而实现食物的精细研磨，使得食物研磨更佳细腻，进一步提高了研磨的效果。而且，采用逐步细化研磨的方式，可以有效减小研磨阻力，保证了研磨过程中的顺畅度。
试验表明，采用本发明一种实施例的研磨组件实现较佳的研磨效果时，驱动电机的转速可以降低到6000rpm以下，可以使95％的食物颗粒尺寸小于0.35mm，并且研磨噪音可以降低到70dB左右。
参照图5所示，在本发明的一些实施例中，第一研磨部210包括沿底盘200的周向分布的多组第一凸齿211，第一凸齿211分布于底盘200的底面，对应的，参照图9所示，第二研磨部110包括呈环状分布的多组第二凸齿111，第二凸齿111分布于研磨件100的下端面，第一凸齿211和第二凸齿111配对设置，从而实现对食物流体的研磨。需要说明的，第一凸齿211和第二凸齿111可以被构造为四棱锥、四棱锥台、三棱锥或者三棱锥台，其加工工艺简单方便，而且利用四棱锥、四棱锥台、三棱锥或者三棱锥台的锐利边角对食物流体进行剪切和挤压，有利于提升研磨破壁的效果；具体的，参照图9所示，第一凸齿211和第二凸齿111的端部可以是尖端、也可以是平面，还可以是刃口，或其他具备剪切食物功能的结构，在此不再具体限定。
在本发明的一些实施例中，第一凸齿211和第二凸齿111之间的配合间隙大于等于0.2mm，从而保障了研磨件100和底盘200在运行过程中的顺畅度，避免发生卡滞现象，从而导致驱动电机发生过载损坏。
参照图5所示，在本发明的一些实施例中，每组对应的第一凸齿211沿底盘200的径向排列，径向排列的两个第一凸齿211之间间隔设有第一流道212，底盘200设有多条沿径向分布的第一流道212，多条第一流道212沿底盘200的中心向周沿延伸，可增加经过第一研磨部210的通水量，进而增大了研磨通道300中食物流体从进口310向出口320流动的速度，提高了研磨组件的研磨效率。可以理解的是，第一流道212为曲线且呈旋涡状分布，可以增大研磨通道300的流速，提高对食物流体的导流速度，从而增加进入研磨通道300的通水量，进一步提高研磨效率；当然，参照图18所示，第一流道212也可以设置为直线。
参照图5所示，在本发明的一些实施例中，相邻的两组第一凸齿211之间沿周向形成有第一环流通道213。第一环流通道213与研磨件100的旋转方向重合，研磨件100在第一环流通道213上高速旋转移动，有利于第一研磨部210和第二研磨部110对食物进行研磨加工，第一环流通道213和第一流道212交错且连通，有助于食物的充分研磨，而且能进一步增大食物流体的流动速度，提高研磨效率。
参照图5所示，在本发明的一些实施例中，底盘200表面形成有凸筋220，凸筋220沿底盘200的中心至周沿的方向上延伸，多条凸筋220呈旋涡状分布，第一流道212形成于相邻的两个凸筋220之间，凸筋220可以用于辅助对食物流体进行剪切、研磨等，也可以用于对食物流体进行快速导流，提高食物流体的流速。在本发明的一些实施例中，第一凸齿211形成于至少部分凸筋220上，便于第一凸齿211的生产加工。
参照图6所示，在本发明的一些实施例中，沿远离底盘200中心的方向上，底盘200的底面被构造为向下凹陷的曲面，曲面有利于食物流体向下流动，减小食物流体阻力，无死角，避免食物流体积聚。可以理解的是，参照图2所示，研磨件100的下端面被构造为与底盘200配合连接的弧形面，弧形面和曲面的配合可以引导食物流体从底盘200的周沿排出，有助于将食物流体再次导流至上刀500，使食物进行循环剪切和研磨，提高破壁的效率。
参照图7和图8所示，在本发明的一些实施例中，研磨件100包括第二连接部120和多个研磨体130，研磨体130可以设有2个、3个、4个或更多个，在此不再具体限定。多个研磨体130分别与第二连接部120连接，多个研磨体130沿第二连接部120向底盘200的周沿延伸，第二研磨部110设于研磨体130的下端面，研磨体130和底盘200配合对食物进行研磨。多个研磨体130沿第二连接部120的周向间隔设置，而且多个研磨体130沿第二连接部120的周向均匀布置，并被构造为呈旋涡状分布，使得多个研磨体130在旋转的过 程中可以将食物流体向下挤压，引导食物流体进入研磨通道300进行研磨，提升了研磨的效果。另外，相邻的研磨体130之间限定出进口310，增大了研磨通道300的进口310的截面面积，进而增大了研磨通道300的通水量。
参照图8和图9所示，在本发明的一些实施例中，研磨体130包括轮辐部131和盘体部132，轮辐部131的一端与第二连接部120连接，另一端与盘体部132连接。具体的，轮辐部131为沿上下方向延伸的弧形，增加了轮辐部131与食物流体之间的接触面积，而且研磨件100运行时阻力更小，降低了驱动电机的功耗。
参照图8所示，在本发明的一些实施例中，轮辐部131的端边1311沿研磨体130的转动方向凸出，使得端边1311呈弧形，降低了与食物流体之间的阻力；而且端边1311设有刀刃，可以提高对食物的切削功能，使得食物在进入研磨通道300前实现进一步的切削，提高研磨的细腻度。
参照图9所示，在本发明的一些实施例中，第二研磨部110包括第二凸齿111，第二凸齿111可设于轮辐部131，或设于盘体部132，又或者同时设于轮辐部131和盘体部132。本实施例中，研磨体130的底部设有多组第二凸齿111，多组第二凸齿111呈环状间隔分布于多个研磨体130的底部，用于对食物进行研磨。需要说明的是，每组对应的第二凸齿111沿研磨体130的径向排列，径向排列的两个第二凸齿111之间间隔设有第二流道112，每个研磨体130设有多条沿径向分布的第二流道112，可增加经过第二研磨部110的通水量，从而增大食物流体的流动速度，提高研磨效率。可以理解的是，第二流道112为曲线且呈旋涡状分布，可以增大食物流体在研磨通道300的流速，从而增加进入研磨通道300的通水量，进一步提高研磨效率。
参照图9所示，在本发明的一些实施例中，相邻的每组第二凸齿111之间沿周向形成有第二环流通道113，第二环流通道113与研磨体130的旋转方向重合，与底盘200的第一环流通道213配合，有利于第二研磨部110和第一研磨部210对食物进行研磨加工，而且进一步增大了食物流体的流动速度，进一步提高了研磨效率，提高了研磨的效果。
可以理解的是，在本发明的一些实施例中，沿研磨体130的中心至外周沿的方向，每组第二凸齿111的分布密度逐渐增大，使得食物流体在研磨通道300中逐步细化地研磨，提升了研磨的顺畅度，避免研磨件100在运行过程中出现卡滞现象。
参照图8和图9所示，在本发明的一些实施例中，相邻研磨体130之间通过加强筋140相连，从而提高了研磨体130的结构强度，提高了研磨件100的结构稳定性。在一些实施例中，加强筋140连接于相邻的研磨体130的盘体部132的外周沿，在提高了研磨体130结构稳定性的同时，也可以保证食物流体进入至研磨通道300的进口310的截面面积的最大化，进而保证了进入到研磨通道300的通水量。
参照图7所示，在本发明的一些实施例中，盘体部132的外周沿设有第一切刀150，第一切刀150朝向上的方向延伸设置，提高了对研磨件100上方的食物的切削功能，与上刀500配合对食物进行充分的切削后，食物更容易进入到研磨通道300内，提高了研磨的效率。
参照图10和图12所示，本发明另一种实施例的研磨件100，包括第二连接部120，以及沿第二连接部120的周向均布且与第二连接部120相连的5个研磨体130，研磨体130包括盘体部132，每个盘体部132沿周向方向的一端向另一端倾斜向下设置。需要说明的是，此处的周向方向可以理解为研磨件100转动时盘体部132的运动方向，参照图10和图11所示，当研磨件100的转动方向为图11中所示的顺时针方向时，盘体部132相对于转动方向的反方向一端向另一端倾斜向下设置，盘体部132可以部分倾斜向下设置，或者整体倾斜向下设置，便于食物流体进入研磨通道300，并使得食物流体在通过研磨通道300时逐渐进行细化研磨，进而实现食物的精细研磨，使食物研磨更加细腻，进一步提高了研磨的效果。
参照图10和图11所示，在本发明的一些实施例中，盘体部132的另一端向外延伸并凸出于轮辐部131，可以理解的是，盘体部132沿研磨件100的转动方向的反方向凸出，即图11中的逆时针方向，从而使盘体部 132与轮辐部131之间形成缺口134，使得盘体部132凸出的部分具有一定的弹性形变量，提升了盘体部132的研磨顺畅度，避免研磨件100在运行过程中因为研磨通道300变小导致的阻力过大现象，使得研磨组件可以适应更多种类的食物的研磨。
参照图12所示，在本发明的一些实施例中，第二研磨部110仅设于盘体部120，轮辐部131的底部为光滑表面，保证了研磨组件的研磨效果的同时，减低了研磨件100的转动阻力。
参照图10和图12所示，在本发明的一些实施例中，研磨体130还包括导向部133，导向部133的一端与盘体部132的周沿连接，导向部133的另一端沿远离盘体部132的方向倾斜向上设置，能够对盘体部132的出口处的食物流体进行导流，使得食物流体从导流部160快速流出，从而加快通过研磨通道300的食物流体的流速，增加经过研磨通道300的通水量，提升了研磨效果。
参照图11所示，在本发明的一些实施例中，导向部133的底部设有沿径向分布的第三流道135，第三流道135可以通过相邻的齿形成，或者在导向部133开槽形成，在此不再限定。第三流道135可以均布于导向部133，也可以在导向部133的局部位置设置，第三流道135可以进一步加快通过导向部133流出的食物流体的流速，而且能对食物流体进行导向，使食物流体能导流至研磨件100的中心进行回流，可增加研磨通道300的通水量，从而增大食物流体的流动速度，提高研磨效率。
参照图13所示，本发明另一种实施例的研磨件100，相邻的研磨件100的导向部133的上端通过加强筋140连接，加强筋140构造为圆环形，用于提高研磨件100的结构强度，而且不会对导向部133的导流效果造成影响，从而保证了食物流体在研磨通道300中的流速，保证了研磨通道300的通水量，从而保证了研磨组件的研磨效率。
参照图3所示，在本发明的一些实施例中，沿研磨体130转动方向的反方向，盘体部132和底盘200之间的间隙b逐渐减小，便于食物流体进入研磨通道300，并使得食物流体在通过研磨通道300时逐步进行细化研磨，进而实现食物的精细研磨，进一步提高了研磨的效果。而且，采用逐步细化研磨的方式，可以有效减小研磨阻力，保证了研磨过程中的顺畅度。
参照图14所示，在本发明的一些实施例中，研磨件100包括位于中心处的第一连接部160、设置于第一连接部160的外周的研磨盘170，以及用于连接研磨盘170和第一连接部160的多个辐条180。其中，研磨盘170呈环状，研磨盘170的周侧设置有多个第二凸齿111，便于与料理机的搅拌杯进行配合，以实现研磨效果。另外，多个辐条180沿周向间隔设置，并且呈弧形延伸，便于辐条180在旋转时，减小流动阻力，提高切削效果。
参照图4所示，在本发明的一些实施例中，研磨组件还包括上刀500，上刀500和研磨件100通过驱动轴400连接，上刀500、研磨件100和底盘200自上而下设置。具体的，上刀500和研磨件100一同安装于驱动轴400，并通过螺钉固定连接于驱动轴400的上端，使得上刀500、研磨件100能够与底盘200实现相对转动，从而提高了研磨组件的研磨效率，使得研磨组件对食物流体的研磨效果更佳。在其中一些实施例中，驱动轴400通过轴承410和油封420与位于底盘200中心的安装位进行连接，其连接稳定可靠。另外，底盘200的内边沿向上的方向延伸设有第一定位部230，第一定位部230与搅拌杯的内壁卡接，以实现底盘200和搅拌杯的周向定位，提高了安装的精度，提升了装配的效率。此外，底盘200的外边沿向外延伸设有第二定位部240，第二定位部240与搅拌杯的底壁连接，以实现底盘200和搅拌杯的上下定位，进一步提高了安装的精度。
参照图15、图16和图17所示，在本发明另一个实施例的研磨组件，包括底盘200和研磨件100，底盘200的底面为平面，且设置有第一研磨部210。研磨件100包括第一连接部160和研磨盘170，研磨盘170围绕第一连接部160的周向分布，研磨盘170被构造为圆环状结构且下端面设有第二研磨部110。第一连接部 160与研磨盘170之间连接有辐条180，辐条180设有多个，多个辐条180沿第一连接部160的周向均匀布置，使得研磨件100的连接结构更加稳定；同时，多个辐条180可实现压水作用，即使食物流体向下运动，提高食物流体通过第一连接部160与研磨盘170之间限定出的进口310的通水量，从而增大进入第一研磨部210和第二研磨部110之间的研磨通道300的流速，从而提高研磨的效率。在本发明的一些实施例中，辐条180倾斜设置，连接第一连接部160的一端高于连接研磨盘170的一端，有助于将食物流体导流至研磨通道300的进口310，增大经过研磨通道300的通水量，进而提高研磨效率。
参照图16和图17所示，在本发明的一些实施例中，辐条180朝向研磨件100的旋转方向的一端边1311沿设有刀刃，即位于辐条180转动方向的迎风面，刀刃对食物进行切削，使得食物在进入研磨通道300前实现进一步的切削，使得食物进一步喜欢，便于后续的研磨操作，提高研磨的细腻度。
参照图18所示，在本发明的一些实施例中，第一研磨部210包括沿周向分布的多组第一凸齿211，每组第一凸齿211呈环状分布于底盘200的底面。而且，沿底盘200的中心至周沿的方向，每组第一凸齿211的分布密度逐渐增大。可以理解的是，图18中有五组环状的第一凸齿211，沿底盘200的中心至周沿方向，第一组的第一凸齿211数量为6个，第二组的第一凸齿211数量为12个，第四组的第一凸齿211数量为72个。通过配合第二凸齿111将食物流体在研磨通道300中逐步细化地研磨，提升了研磨的顺畅度，避免研磨组件在运行过程中出现卡滞现象。
参照图19所示，在本发明的一些实施例中，底盘200的底面沿远离中心的方向向上倾斜延伸，使得研磨通道300的进口310的截面面积更大，有利于增大研磨通道300的通水量，而且可以减小食物流体进入到研磨通道300的阻力，有利于食物流体流动，更有利于研磨。
参照图16所示，沿远离底盘200中心的方向，研磨通道300在上下方向的间隙c逐渐减小，间隙c逐渐减小可以使食物在离心力的作用下沿底盘200的中心向四周流动的过程中，逐步实现粗磨、半精磨到精磨的过程，使得食物流体逐步进行细化研磨，进而实现食物的精细研磨，使得食物研磨更佳细腻，进一步提高了研磨的效果。而且，采用逐步细化研磨的方式，可以有效减小研磨阻力，保证了研磨过程中的顺畅度。
参照图20所示，在本发明的一些实施例中，第二研磨部110包括呈环状分布的多组第二凸齿111，对应的第二凸齿111沿研磨盘170的径向排列且设有沿径向分布的第二流道112，为了进一步增加经过第二研磨部110的通水量，第二流道112上开设有导流槽114，导流槽114可以进一步增加研磨通道300的截面积，从而增大食物流体的流动速度，提高研磨效率。可以理解的是，第二流道112为直线且呈放射状分布，可以增大食物流体在研磨通道300的流速，从而增加进入研磨通道300的通水量，进一步提高研磨效率。
参照图20所示，在本发明的一些实施例中，沿研磨盘170的中心至外周沿的方向，每组第二凸齿111的分布密度逐渐增大。可以理解的是，图20中有四组环状的第二凸齿111，沿研磨盘170的中心至外周沿方向，第一组的第二凸齿111数量为6个，第二组的第二凸齿111数量为12个，第三组的第二凸齿111数量为36个，第四组的第二凸齿111数量为72个。通过配合第一凸齿211实现将食物流体在研磨通道300中逐步细化地研磨，提升了研磨的顺畅度，避免研磨组件在运行过程中出现卡滞现象。
参照图20所示，在本发明的一些实施例中，相邻的两组第二凸齿111之间沿周向形成有第二环流通道113。第二环流通道113与研磨盘170的旋转方向重合，与底盘200的第一环流通道213配合，有利于第二研磨部110和第一研磨部210对食物进行研磨加工，而且进一步增大了食物流体的流动速度，进一步提高了研磨效率，提高了研磨的效果。
参照图21所示，本发明另一种实施例的研磨组件，包括底盘200和研磨件100，底盘200与上一个实施例的结构相同，可适当参考上一个实施例进行理解，为了避免重复，本实施例中不再赘述。具体的，参照图22所示，在本发明的一些实施例中，研磨件100包括第一连接部160和研磨盘170，第一连接部160和研磨 盘170之间通过辐条180固定连接，第一连接部160设有沿研磨盘170延伸的第一刀叶190，第一刀叶190与辐条180错位布置，第一刀叶190可以与辐条180相互配合，交错地对食物进行切削，使得食物得到更充分的细化，提高切削的效率。另外，第一刀叶190设于两个相邻的辐条180之间，可以直接向两个辐条180之间的进口310挤压食物流体，有效增大经过研磨通道300的通水量，进而提高研磨效率。
参照图22所示，在本发明的一些实施例中，研磨盘170的周沿设有第二切刀171，第二切刀171朝向上的方向延伸设置，与第二研磨部110位于研磨件100的相反面，能够实现对食物的切削，使得食物经过充分的切削后再进行研磨，提升了研磨组件的研磨效果。
参照图23所示，在本发明的一些实施例中，辐条180设有第二刀叶181，第二刀叶181朝向下的方向延伸设置。第二刀叶181用于把食物由第一连接部160向研磨盘170扩散，第二刀叶181与第二研磨部110位于研磨件100的同一面。研磨件100转动时，第二刀叶181搅拌食物，由于离心力的作用，把食物由第一连接部160向研磨盘170扩散，使得更多的食物进入到研磨通道300进行研磨，有助于提高研磨效率。而且，第二刀叶181还具有对食物流体的切削功能。
本发明一种实施例的料理机，通过采用本发明的第一方面实施例的研磨组件，食物在研磨件100与底盘200在相对转动的过程中被导流至第一研磨部210和第二研磨部110之间的研磨通道300，从而对食物进行精细的研磨，能够使料理机在较低转速下达到较好的研磨性能，降低了料理机工作噪音，提升了用户体验；另外，通过在研磨件100设有研磨通道300的进口310，研磨件100的外周沿和底盘200的周沿之间设有研磨通道300的出口320，因此食物可以在料理机内实现循环研磨，使得食物研磨更加细腻，提高了料理机的研磨效果及整体品质。
上面结合附图对本发明实施例作了详细说明，但是本发明不限于上述实施例，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化。
