参照图1和图2所示，本发明一种实施例的研磨刀100，应用于破壁机等料理设备，通过研磨刀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刀100，包括连接部110，连接部110位于研磨刀100的中心，连接部110通过驱动轴300与驱动电机(图中未示出)连接。
参照图1和图2所示，本发明一种实施例的研磨刀100，还包括研磨体120，研磨体120与连接部110连接，研磨体120与连接部110可采用一体成型工艺制造，或采用焊接等方式进行固定。具体的，参照图9和图10所示，研磨体120沿远离连接部110的方向倾斜向下延伸，而且研磨体120的底部设有研磨部130，使得驱动轴300带动研磨刀100转动过程中，食物可以被导流至研磨刀100和底盘200的研磨间隙中，研磨部130对食物进行研磨，使得食物颗粒尺寸小于0.35mm，实现食物的破壁研磨。而且在研磨刀100的作用下，食物会沿研磨刀100的外周沿方向流动，即离心方向，在食物流动的方向上，研磨间隙逐渐减小，从而使食物研磨更加细腻，研磨效果更佳。
参照图3所示，在本发明的一些实施例中，研磨体120设有多个，可以理解的是，研磨体120可以设为2个、3个、4个、5个或更多个，在此不再具体限定。具体的，多个研磨体120分别沿连接部110的周向间隔设置，而且多个研磨体120沿连接部110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120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间隙进行研磨，提升了研磨的效果。
参照图2和图3所示，在本发明的一些实施例中，研磨体120包括轮辐部121和盘体部122，轮辐部121的一端与连接部110连接，另一端与盘体部122连接。具体的，轮辐部121沿上下方向呈弧形，增加了轮辐部121与食物流体之间的接触面积，而且研磨刀100的运行阻力更小，降低了驱动电机的功耗。
参照图3所示，在本发明的一些实施例中，轮辐部121的端边1211沿研磨体120的转动方向凸出，使得端边1211呈弧形，降低了与食物流体之间的阻力；而且端边1211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间隙前实现进一步的切线，提高研磨的细腻度。
参照图4所示，在本发明的一些实施例中，研磨部130包括凸齿131，凸齿131可设于轮辐部121，或设于盘体部122，又或者同时设于轮辐部121和盘体部122。本实施例中，研磨体120的底部设有多组凸齿131，多组凸齿131呈环状间隔分布于多个研磨体120的 底部，用于对食物进行研磨。可以理解的是，凸齿131被构造为四棱锥或者四棱锥台，其加工工艺简单方便。另外，每组对应的凸齿131沿研磨体120的径向排列，径向排列的两个凸齿131之间间隔设有第一流道140，每个研磨体120设有多条沿径向分布的第一流道140，可增加经过研磨部130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4所示，在本发明的一些实施例中，相邻的每组凸齿131之间沿周向形成有第二流道150，第二流道150与研磨刀100的旋转方向重合，有利于研磨部130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120的中心至外周沿的方向，每组凸齿131的分布密度逐渐增大，使得食物流体在研磨间隙中逐渐细分地研磨，提升了研磨的顺畅度，避免研磨刀100在运行过程中出现卡滞现象。
参照图1和图3所示，在本发明的一些实施例中，相邻研磨体120之间通过加强筋123相连，从而提高了研磨体120的结构强度，提高了研磨刀100的结构稳定性。在一些实施例中，加强筋123连接于相邻的研磨体120的盘体部122的外周沿，在提高了研磨体120结构稳定性的同时，也可以保证食物流体进入至研磨间隙的进口的截面面积的最大化，进而保证了进入到研磨间隙的通水量。
参照图1所示，在本发明的一些实施例中，盘体部122的外周沿设有切刀124，切刀124朝向上的方向延伸设置，提高了对研磨刀100上方的食物的切削功能，提升了研磨刀100的研磨效果。
参照图5和图7所示，本发明另一种实施例的研磨刀100，包括连接部110，以及沿连接部110的周向均布且与连接部110相连的5个研磨体120，研磨体120包括盘体部122，每个盘体部122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刀100转动时盘体部122的运动方向，参照图5和图6所示，当研磨刀100的转动方向为图6中所示的顺时针方向时，盘体部122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122可以部分倾斜向下设置，或者整体倾斜向下设置，在此不再具体限定。参照图7所示，盘体部122倾斜向下设置，使得位于盘体部122上的研磨部130与盘体部122的最低点所在的水平面之间形成间隙c，而且间隙c逐渐减小，便于食物流体进入研磨间隙，并使得食物流体在通过研磨间隙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5和图6所示，在本发明的一些实施例中，盘体部122的另一端向外延伸并凸出于轮辐部121，可以理解的是，盘体部122沿研磨刀100的转动方向的反方向凸出，即 图6中的逆时针方向，从而使盘体部122与轮辐部121之间形成缺口170，使得盘体部122凸出的部分具有一定的弹性形变量，提升了盘体部122的研磨顺畅度，避免研磨刀100在运行过程中因为研磨间隙变小导致的阻力过大现象，使得研磨刀100可以适应更多种类的食物的研磨。
参照图7所示，在本发明的一些实施例中，研磨部130仅设于盘体部120，轮辐部121的底部为光滑表面，保证了研磨刀100的研磨效果的同时，减低了研磨刀100的转动阻力。
参照图5和图7所示，在本发明的一些实施例中，研磨刀100还包括导向部160，导向部160与盘体部122的周沿连接，导向部160远离盘体部122的一端向外侧倾斜向上设置，能够对盘体部122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，从而加快通过研磨间隙的食物流体的流速，增加经过研磨部130的通水量，提升了研磨效果。
参照图6所示，在本发明的一些实施例中，导向部160的底部设有沿径向分布的第三流道180，第三流道180可以通过相邻的齿形成，或者在导向部160开槽形成，在此不再限定。第三流道180可以均布于导向部160，也可以在导向部160的局部位置设置，第三流道180可以进一步加快通过导向部160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刀100的中心进行回流，可增加经过研磨部130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8所示，本发明另一种实施例的研磨刀100，相邻的研磨刀100的导向部160的上端通过加强筋123连接，加强筋123构造为圆环形，用于提高研磨刀100的结构强度，而且不会对导向部160的导流效果造成影响，从而保证了食物流体在研磨间隙中的流速，保证了研磨间隙的通水量，从而保证了研磨刀100的研磨效率。
参照图9和图10所示，本发明一种实施例的研磨组件，研磨组件一般安装于料理机的搅拌杯(图中未示出)的底部，搅拌杯内形成有用于放置食物的搅拌腔(图中未示出)，研磨组件对食物进行切割、研磨等操作，使得食物流体在搅拌腔内形成旋涡循环，从而实现食物的破壁加工。本发明实施例的研磨组件，包括以上实施例的研磨刀100，研磨刀100设置与连接部110相连且底部设有研磨部130的研磨体120，研磨体120沿远离连接部110的方向倾斜向下延伸，使得在转动过程中可以将食物导流至研磨刀100和底盘200的研磨间隙中，研磨部130对食物进行研磨，提升了研磨效果。
参照图10所示，本发明一种实施例的研磨组件，还包括底盘200，底盘200的上表面设有研磨齿210，底盘200与研磨刀100转动连接，驱动研磨部130与研磨齿210配合对食物进行研磨。在一些实施例中，沿底盘200的中心至内周沿的方向，研磨体120和底盘 200之间的间隙a逐渐减小，使得食物流体在通过研磨间隙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11所示，在本发明的一些实施例中，沿研磨体120转动方向的反方向，至少部分研磨体120和底盘200之间的间隙b逐渐减小，便于食物流体进入研磨间隙，并使得食物流体在通过研磨间隙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12所示，研磨组件还包括上刀400和底盘200，上刀400和研磨刀100通过驱动轴300连接，具体的，连接部110与上刀400一同安装于驱动轴300，并通过螺钉固定连接于驱动轴300的端部，使得上刀400和研磨刀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。
参照图12所示，驱动轴300通过轴承310和油封320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220，第一定位部220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230，第二定位部230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。
本发明一种实施例的料理机，包括以上实施例的研磨组件。本发明实施例的料理机，通过研磨组件设置与连接部110相连且底部设有研磨部130的研磨体120，研磨体120沿远离连接部110的方向倾斜向下延伸，使得在转动过程中可以将食物导流至研磨刀100和底盘200的研磨间隙中，研磨部130对食物进行研磨，而且食物沿离心方向研磨过程中研磨间隙逐渐减小，从而使食物研磨更加细腻，提升了料理机的研磨效果。
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。
