技术领域
本发明涉及家用电器领域，更具体而言，涉及一种粉碎刀及食物处理机。
背景技术
目前，现有的搅拌器的粉碎刀的刀叶一般都倾斜向下地安装在安装轴上，因此，在工作时，在电机超高速带动下，粉碎刀向下压物料的效果非常好，从而杯体内的物料很快就会被排出到杯体底部，而当杯体底部的物料越积越多时，物料就会顺着杯体的侧壁向上运动，从而实现物料的不断循环，但该种结构，由于杯体中上部的物料在刀叶的作用下能够快速向下排出到底部，而底部的物料只能依靠物料堆积后的挤压力向上运动，并在运动到一定高度位置后，在重力的作用下掉落回至杯体中部，这种物料的循环方式由于杯体上部的物料向下的排出速度低于杯体底部的食物向上运动的速度，即粉碎刀中上部的位置就会因为上部物料补充速度慢于下部的排出速度而形成空隙及负压，因此上部回流的物料再补充到此处空隙时就会不稳定，而导致产生较大的波动，从而会导致物料的循环翻滚运动不合理，同时电机工作时的负载也不是持续稳定的，如此一来，一方面会导致搅拌器的功率波动大，温升高，噪音大等问题，另一方面会导致产品的粉 碎效率低，粉碎效果不好等问题。
因此，如何设计出一种新的功率波动小，温升低，噪音小，粉碎效率低，粉碎效果好的粉碎刀及食物处理机成为目前亟待解决的问题。
发明内容
本发明旨在至少解决现有技术中存在的技术问题之一。
为此，本发明的一个目的在于，提供了一种粉碎刀。
本发明的另一个目的在于，提供一种包括上述粉碎刀的食物处理机。
为实现上述目的，本发明第一方面的实施例提供了一种粉碎刀，用于食物处理机，包括：安装轴，所述安装轴包括安装端和连接端；至少一个第一刀叶，所述第一刀叶安装在所述安装轴上，所述第一刀叶上设置有第一刀刃，所述第一刀刃设置在所述第一刀叶远离所述安装端的一面上；至少一个第二刀叶，所述第二刀叶安装在所述安装轴上，所述第二刀叶上设置有第二刀刃，所述第二刀刃设置在所述第二刀叶靠近所述安装端的一面上；其中，所述第一刀叶倾斜安装在所述安装轴上和/或所述第二刀叶倾斜安装在所述安装轴上，所述第一刀叶和所述第二刀叶的厚度为H，厚度H的值为：1mm≤H≤5mm。
根据本发明的实施例提供的粉碎刀，安装在搅拌器等食物处理机的杯体内，用于对杯体内的物料进行粉碎及推送，具体地，安装轴的安装端用于安装第一刀叶和第二刀叶，安装轴的连接端用于与驱动装置，比如电机驱动连接，以在驱动装置，比如电机的作用下驱动第一刀叶和第二刀叶转动，以对物料进行粉碎及推送，当然，安装轴也可以直接是电机的电机轴，而两个或两个以上第一刀叶上的第一刀刃设置在第一刀叶远离安装端的一面上，即靠近连接端的一面上，也即第一刀刃设置在第一刀叶的下端面上，也即第一刀刃的开口朝下，因此第一刀叶在安装轴的作用下旋转时，便能够边粉碎物料，边将物料向杯体底部及杯体的外侧推送，从而能够使物料从上至下循环运动，而当被推送到的杯体底部的物料越积越多时，先被推送至杯体底部的物料在后被推送至杯体底部的物料的挤压下，便能够顺着杯体的侧壁向上运动，以实现物料从下至上的循环运动，而在物料从下至上运动到杯体的上部时，物料便能够在重力的作用下掉落下来，而后再被 第一刀刃粉碎及向下向外推送，至此即可实现物料的一个完整循环，该种循环方式由于物料在第一刀刃的作用下由上至下及由下至下循环运动时，第一刀刃向下推送物料的速度，即物料向下推送速度要快于物料从杯体上部掉落下来的速度，即物料的回流速度，从而会导致杯体中部形成空隙进而形成负压，因此当杯体上部的物料再次回流而补充到该空隙时就会导致物料的波动，进而导致物料的循环翻滚运动不合理，进而使得物料不能够按规定的循环路线和理想的粉碎方位进行运动，而第二刀刃设置在第二刀叶靠近安装端的一面上，即第二刀刃设置在第二刀叶的上端面上，也即第二刀刃的开口朝上，因此，第二刀叶在安装轴的作用下旋转时，便能够边粉碎物料，边将杯体中上部的周边的物料聚集抽取到杯体中上部的中间，然后随着从杯体上部掉落下来的物料一起被第一刀刃粉碎及向下向外推送，从而通过设置第二刀刃，第二刀刃便能够将杯体中上部的周边的物料聚集抽取到杯体中上部的中间，以填补到物料循环过程中形成的空隙内，从而即可消除物料循环过程中形成的缝隙和负压，进而当杯体上部的物料再次回流时，便能够非常平稳地与第二刀刃抽取的物料混合，进而被第一刀刃粉碎并向下推送，因而即可避免物料的波动，以使物料能够按规定的循环路线和理想的粉碎方位进行循环运动，进而一方面便能够对物料进行有效粉碎，以确保物料的加工效率和加工效果，另一方面可减小因物料波动而对安装轴的冲击，进而使得安装轴能够更为平稳地转动，进而即可减小搅拌器的波动，以使搅拌器平稳地转动，而搅拌器平稳地转动会降低搅拌器的噪音和摩擦生热，进而能够降低搅拌器的温升等。同时，该种设置由于物料循环时没有形成空隙，因而第一刀叶的第一刀刃能够始终作用在物料上，从而便能够提高粉碎刀对物料的粉碎效率，确保粉碎刀对物料的粉碎效果，而通过第二刀叶的第二刀刃的粉碎作用，能够进一步提高粉碎刀对物料的粉碎效率，进而能够进一步确保粉碎刀对物料的粉碎效果。其中，将第一刀叶和第二刀叶的厚度H设置在大于等于1mm小于等于5mm的范围内即能够确保第一刀叶和第二刀叶的强度，又能够防止第一刀叶和第二刀叶的厚度过厚。
其中，优选地，第一刀叶和第二刀叶中至少有一个倾斜设置，即要么 第一刀叶倾斜设置，要么第二刀叶倾斜设置，要么第一刀叶和第二刀叶同时倾斜设置，同时，优选地，第一刀叶位于第二刀叶远离安装端的一方，该种设置能够使第一刀叶和第二刀叶形成高度差，因而能够更好地利用位于下方的第一刀叶来将物料向下推送，及更好地利用位于上方的第二刀叶来将物料补充到第一刀叶形成的空隙内。
在上述技术方案中，优选地，所述第一刀刃与所述第一刀叶和/或所述第二刀刃与所述第二刀叶为一体式结构。

在上述技术方案中，优选地，所述第一刀刃设置在所述第一刀叶的一侧上，所述第二刀刃设置在所述第二刀叶的一侧上。
在该技术方案中，可只在第一刀叶和第二刀叶的单侧上设置刀刃，因为，搅拌器在搅拌食物时都是沿同一方向搅拌粉碎食物，因此，在第一刀叶和第二刀叶的单侧上设置刀刃即可满足产品的要求，而只在第一刀叶和第二刀叶的单侧上设置刀刃能够简化第一刀叶和第二刀叶的结构，因而能够简化加工工序，降低加工成本。
在另一技术方案中，优选地，所述至少一个第一刀叶的两侧上均设置有所述第一刀刃，和/或所述至少一个第二刀叶的两侧上均设置有所述第二刀刃。
在该技术方案中，通过在第一刀叶的两侧设置第一刀刃，使得第一刀叶的两侧均能够用于物料粉碎，因而第一刀叶无论是顺时针旋转还是逆时针旋转均能够对物料进行粉碎，进而能够实现第一刀叶的双面粉碎。同理，通过在第二刀叶的两侧均设置第二刀刃，使得第二刀叶的两侧均能够用于物料粉碎，因而第二刀叶无论是顺时针旋转还是逆时针旋转均能够对物料进行粉碎，进而能够实现第二刀叶的双面粉碎。
其中，优选地，所述至少一个第二刀叶中至少有一个所述第二刀叶位于一所述第一刀叶靠近所述安装端的一方，即至少有一个第二刀叶位于一第一刀叶的上方，以使第一刀叶和第二刀叶能够形成两层或两层以上设置，以便能够对食材进行分层切割，进而便能够提高粉碎刀对食材的粉碎效率和粉碎效果。

在该技术方案中，第二刀叶的一端安装在安装轴上，第二刀叶的另一端向安装端的端部方向倾斜延伸，即第二刀叶倾斜向上设置，该种设置由于第二刀叶倾斜向上设置，因此，便能够更高效地将杯体内中上部的食材聚集抽取到第一刀叶形成的空隙内，以使食材流动的更加平稳。而在第二刀叶倾斜向上设置时，第一刀叶即可倾斜向下设置，也可倾斜向上设置，也可垂直于安装轴设置，但优选地，可将第一刀叶倾斜向下设置或倾斜向上设置，而通过将第一刀叶倾斜设置，即非水平设置，使得第一刀叶能够更好地与物料接触，因而能够提高第一刀叶对物料的粉碎及向下向外的推送效果，进而即可提高产品的粉碎效率，确保产品的粉碎效果。其中，具体地，在两个或两个以上第一刀叶呈双层设置时，可将上层的第一刀叶倾斜向上设置，而将下层的第一刀叶倾斜向下设置，以便能够使产品的结构分布的更加合理紧凑。

在上述技术方案中，优选地，所述第二刀叶的数量为两个或两个以上，两 个或两个以上所述第二刀叶对称地安装在所述安装轴上，或两个或两个以上所述第二刀叶沿所述安装轴的周向均匀分布。
在该技术方案中，第二刀叶的数量为两个或两个以上，因而能够通过两个或两个以上第二刀叶同时粉碎物料及同时将杯体中上部的周边的物料聚集抽取到杯体中上部的中间，进而能够加大第二刀叶同时对物料的粉碎效果及对周边物料的聚集抽取效果，因而能够将更多的物料填补到物料循环过程中形成的空隙内，进而能够进一步减小物料的波动及物料对转动轴的冲击，以使产品能够更加平稳、低噪音、低温升、高效率地运行。而两个或两个以上第二刀叶对称设置或均匀分布在安装轴的周向上，能够使第二刀叶对各个角度上的食材的聚集抽取的效果一致，因而能够使杯体内的各个角度上的食材流动的更加顺畅、平稳。

在上述技术方案中，优选地，所述第一刀叶的数量为偶数个，所述第二刀叶的数量为偶数个。
在该技术方案中，第一刀叶和第二刀叶的数量为偶数个，能够使两两第一刀叶和两两第二刀叶呈对称设置，进而能够使第一刀叶和第二刀叶受到的物料的阻力一致，因而能够使第一刀叶和第二刀叶的受力更加均衡，以防止出现受力薄弱部，进而即能够相对提高第一刀叶和第二刀叶的强度，同时，该种设置能够依次形成四叶刀或八叶刀或十二叶刀等多种规格，进而能够提高粉碎刀的规格。此外中心对称地结构更易加工，因而能够降低产品的加工难度，提高产品的加工效率，降低产品的加工成本。
当然，第一刀叶的数量和第二刀叶的数量也可为奇数个，从而可对应形成三叶刀、五叶刀、七叶刀等多种规格。
在上述技术方案中，优选地，所述第一刀叶的数量为两个或四个或六个；和/或所述第二刀叶的数量为两个或四个。

在上述技术方案中，优选地，粉碎刀还包括：第一刀根部，所述第一刀根部套设安装在所述安装轴上；第二刀根部，所述第二刀根部套设安装在所述安装轴上，并位于所述第一刀根部靠近所述安装端的一方；其中，所述至少一个第一刀叶设置在所述第一刀根部上或所述至少一个第一刀叶设置在所述第一刀根部和所述第二刀根部上；所述至少一个第二刀叶设置在所述第二刀根部上。
在该技术方案中，可在安装轴上设置两个刀根部，即第一刀根部和第二刀根部，从而能够将至少一个第一刀叶和至少一个第二刀叶安装在第一刀根部或第二刀根部上，以使粉碎刀形成双层结构，其中，具体地，在第一刀叶的数量和第二刀叶的数量相等时，可将所有的第一刀叶全部安装在下层，即第一刀根部上，同时将所有的第二刀叶全部安装在上层，即第二刀根部上，而在第一刀叶的数量比第二刀叶的数量多时，可将大部分第一刀叶安装在下层，即第一刀根部上，而将剩下的第一刀叶与所有的第二刀叶交替对称地安装在上层，即第二刀根部上，此时，优选地，将第二刀根部上的第一刀叶倾斜向上设置，以使其倾斜方向能够与第二刀叶的倾斜方向一致，从而即可确保产品的美观性和对称性。

在该技术方案中，可在第一刀根部上设置第一通孔，而在第二刀根部上设置第二通孔，从而可将安装轴的安装端依次穿过第一通孔和第二通孔，以实现第一刀叶和第二刀叶的精确安装。

在上述技术方案中，优选地，所述第一刀根部和所述第二刀根部的形状大小一致。
在该技术方案中，第一刀根部和第二刀根部的形状大小一致，一方面能够使第一刀叶和第二刀叶的强度一致，另一方面能够提高减少零部件的类型，以利于产品的标准化。当然，在另一技术方案中，第一刀根部和第二刀根部的形状大小也可不一致。
在上述技术方案中，优选地，所述第一刀根部和/或所述第二刀根部为方形、圆形，三角形，椭圆形或五边形，具体地，第一刀根部和/或第二刀根部 的形状可根据第一刀叶和第二刀叶的数量变化而变化。
在该技术方案中，第一刀根部和/或第二刀根部优选为方形，因为方形相比于圆形、椭圆形而言更易加工，因而能够降低产品的加工成本，提高产品的加工效率。具体地比如，该种结构使得第一刀叶和第二刀叶能够通过金属板快速简单地折弯形成，而圆形则无法通过金属板直接折弯形成。当然，第一刀根部和/或第二刀根部也可为圆形，三角形，椭圆形，五边形或者任意其它形状。
在上述技术方案中，优选地，所述第一刀根部与所述安装轴相互垂直安装，所述第二刀根部与所述安装轴相互垂直安装。

在上述技术方案中，优选地，所述安装轴为圆形轴。
在该技术方案中，安装轴优选为圆形轴，因为圆形轴更易与电机等配合，从而能够更利于对安装轴进行驱动。
在上述技术方案中，优选地，第一刀叶和/或第二刀叶由金属材料制成，因为，金属材料的强度高，耐磨性好，因而能够更好地粉碎物料。当然，第二刀叶和/或第一刀叶也可为其它硬度比较高的材料制成。
在上述技术方案中，优选地，所述第一刀叶远离所述安装轴的一端上设置有压板。
在该技术方案中，通过在第一刀叶远离安装轴的一端(即第一刀叶的尾部)上设置压板，从而能够通过压板来向将物料推送至杯体底部，而压板的设置能够增大第一刀叶与物料的接触面积，因而能够增大第一刀叶对物料的推力，进而能够加快物料的循环速度，因而能够提高产品的粉碎效 率。
在上述技术方案中，优选地，所述压板与所述第一刀叶之间的角度为γ，其中，夹角γ的值为：90°<γ≤180°，进一步优选地，135°≤γ≤180°。
在该技术方案中，通过将压板与第一刀叶之间的夹角设置在大于等于135°小于等于180°的范围内，能够确保第一刀叶向下向外侧的压水作用，以便能够使物料的内外循环快速，顺畅，同时该种设置还能够加大第一刀叶的切割投影面积，因而能最大限度的提高粉碎效果和粉碎效率。
其中，进一步优选地，夹角γ的值为：160°≤γ≤170°。
在上述技术方案中，优选地，所述至少一个第二刀叶的总长度之和与所述至少一个第一刀叶的总长度之和的比值为A，其中，0.05≤A≤0.8。
在该技术方案中，至少一个第二刀叶的总长度之和与至少一个第一刀叶的总长度之和的比值A，即所有第二刀叶的总长度之和与所有第一刀叶的总长度之和的比值A不宜过大也不宜过小，具体地，若A值过小，则第二刀叶的对物料的抽取聚集效率低，从而导致第二刀叶无法填补第一刀叶形成的空隙，从而会导致物料的循环的效率低，因而会造成物料的粉碎效果差，但若A值过大，则第二刀叶对物料的抽取聚集效率偏高，从而导致第一刀叶无法及时将中部的物料排出至杯体的底部，进而会造成物料推挤，因而也会导致物料的循环的效率低，从而会造成物料的粉碎效果差，而通过将比值A设置在大于等于0.05小于等于0.8的范围内，即能够确保杯体内物料的循环平衡稳定，又能够提高物料的粉碎效果和粉碎效率，进而会提高产品的整体品质。
其中，优选地，0.1≤A≤0.4，即比值A的值优选设置在大于等于0.1小于等于0.4的范围内，该种设置，能够使物料的循环达到最佳的平衡状态，因而能够进一步提高物料的粉碎效果和粉碎效率，以进一步提高产品的整体品质。
在上述技术方案中，优选地，所述第二刀叶与所述安装轴的横截面之间的夹角为α，其中，夹角α的值为：正45°≤α≤正70°。
在该技术方案中，第二刀叶与安装轴的横截面即水平面之间的夹角α优选在大于等正45°小于等于正70°的范围内，即第二刀叶优选在安装轴上 逆时针向上倾斜45°至70°设置，该种设置使得第二刀刃的切割面积和对物料的抽取效果比较适中，因而能够在粉碎刀正常安装到杯体内时，使得第二刀叶能够与第一刀叶更好地配合，以更平衡稳定地弥补因第一刀刃的推送而形成的空隙，进而能够使物料平衡稳定地循环运动，反之若角度α太小，则第二刀叶切割面积大，抽水效果好，因而会导致第二刀叶对物料的抽取速度大于第一刀叶对物料的排出速度，从而会导致物料循环不充分，而若角度α太大，则第二刀叶切割面积小，抽水效果差，也会导致第二刀叶对物料的抽取速度小于第一刀叶对物料的排出速度，因而也不能实现物料的平衡，而将夹角α设置在大于等正45°小于等于正70°的范围内，使得第二刀叶对物料的抽取比较适中，因而即能够与第一刀叶更好地配合，以实现物料的排出与抽取的平衡，进而能够使物料平衡稳定地循环运动，以确保物料的粉碎效率和粉碎效果。
其中，在本说明书中，逆时针旋转的角度为正，顺时针旋转的角度为负。
其中，优选地，正50°≤α≤正60°，该种设置能够更好地实现物料的排出与抽取的平衡，进而能够更好地使物料平衡稳定地循环运动，以更好地确保物料的粉碎效率和粉碎效果。
在上述技术方案中，优选地，所述第一刀叶与所述安装轴的横截面之间的夹角为β，其中，夹角β的值为：负45°≤β≤正45°。
在该技术方案中，第一刀叶与安装轴的横截面之间的夹角β优选大于等于负45°小于等于正45°的范围内，即第一刀叶在安装轴上即可顺时针向下倾斜0°至45°设置，优选为顺时针向下倾斜10°至20°设置，也可在安装轴上逆时针向上倾斜0°至45°设置，优选为逆时针向上倾斜10°至20°设置，该种设置使得第一刀刃的切割面积和对物料的推送效果比较适中，因而能够在粉碎刀正常安装到杯体内时，使得第一刀叶能够与第二刀叶更好地配合，以更平衡稳定地弥补因第一刀叶的推送而形成的空隙，进而能够使物料平衡稳定地循环运动，反之若角度β太小，则第一刀叶切割面积大，物料排出效果好，因而会导致第一刀叶对物料的排出速度大于第二刀叶对物料的抽取速度，从而会导致物料循环不充分，而若角度β太大，则第一刀叶切割面积小，物料的排出速度慢，从 而也会导致第一刀叶对物料的排出速度小于第二刀叶对物料的抽取速度，因而也不能实现物料的平衡，而将夹角β设置在大于等于负45°小于等于正45°的范围内即能够实现物料的排出与抽取的平衡，进而能够使物料平衡稳定地循环运动，以确保物料的粉碎效率和粉碎效果。此外，负45°≤β≤正45°使得β具有较宽的取值范围，从而可将第一刀叶的数量设置成两个或两个以上，并将两个或两个以上第一刀叶以不同角度和/或不同高度地安装在安装轴上，以便能够实现两个或两个以上第一刀叶的梯级安装，进而能够利用两个或两个以上第一刀叶实现对物料的梯级粉碎及梯级推送，因而即能够确保物料的粉碎效率和粉碎效果。

在该技术方案中，四个第一刀叶安装在安装轴的同一横截面，即第一横截面上，另外两个第一刀叶和两个第二刀叶安装在安装轴的另一同一横截面，即第二横截面上，使得六个第一刀叶和两个第二刀叶形成的八叶刀能够分成上下两层，进而能够对物料进行分层粉碎及分层推送，而第二横截面上的两个第一刀叶与安装轴优选呈0°-正45°的夹角，进一步优选呈正 10°-正20°的夹角，而第一横截面上的四个第一刀叶中的两个第一刀叶与安装轴优选呈负45°-0°的夹角，进一步优选呈负20°-负10°的夹角，而另外两个第一刀叶与安装轴优选呈负20°-正20°的夹角，进一步优选呈负10°-正10°的夹角，使得六个第一刀叶能够上下分成三层，因而能够对物料分三层进行粉碎及推动，而将六个第一刀叶安装在上述范围内，并将第二横截面上的两个第二刀叶与安装轴的横截麦面优选呈正45°-正70°的夹角，进一步优选呈正50°-正60°的夹角，使得第一刀叶对物料的切割面积和对物料的推送效果比较适中及使得第二刀叶对物料的切割面积和对物料的抽取效果比较适中，因而便能够使第一刀叶与第二刀叶更好地配合，以实现物料的排出与抽取的平衡，进而能够使物料平衡稳定地循环运动，以确保物料的粉碎效率和粉碎效果。
在上述技术方案中，优选地，粉碎刀还包括：泄压孔，设置在所述第一刀叶上和/或所述第二刀叶上。
在该技术方案中，通过设置泄压孔能够在第一刀叶和/或第二刀叶推送物料时为第一刀叶和/或第二刀叶泄压，以防止第一刀叶和/或第二刀叶因压力过大而折断，具体地，比如，在第一刀叶将物料推送至杯体底部时，若杯体底部的物料聚集的过多，则物料对第一刀叶的阻力较大，而通过设置泄压孔可利用物料与第一刀叶之间的挤压，以使物料能够从泄压孔内排出，从而对第一刀叶起到泄压的作用，进而即可使第一刀叶经久耐用而不易折断，因而即可延长产品的使用寿命，同理，在第二刀叶抽取物料时，若抽取的物料过多，则物料对第二刀叶的阻力较大，而通过设置泄压孔可利用物料与第二刀叶之间的挤压，以使物料能够从泄压孔内排出，从而对第二刀叶起到泄压的作用，进而即可使第二刀叶经久耐用而不易折断，因而也可延长产品的使用寿命。当然，我们也可只在第一刀叶上设置泄压孔，而不在第二刀叶上设置泄压孔。
在上述技术方案中，优选地，所述泄压孔的数量为一个或一个以上。
在该技术方案中，泄压孔的数量为一个或多个，具体地，可在第一刀叶和第二刀叶上均设置泄压孔，从而能够同时利用多个泄压孔进行泄压，以提高粉碎刀的强度，进而即可防止粉碎刀破碎。
在上述技术方案中，优选地，所述至少一个第一刀叶上均设置有所述泄压孔，且所述至少一个第一刀叶上设置的所述泄压孔的形状大小一致。
在该技术方案中，可将第一刀叶上均设置上泄压孔，从而能够对所有的第一刀叶进行泄压，以大幅度提高粉碎刀的整体抗压能力，而一个或两个或两个以上第一刀叶上的泄压孔的形状大小一致使得每个第一刀叶的泄压能力一样，进而能够使每个第一刀叶对物料的推送效果一致，进而即可使杯体的内的物料平稳地运动，以防止物料波动。当然，也可只在部分第一刀叶上设置泄压孔，而在其余部分的第一刀叶上不设置泄压孔。
在上述技术方案中，优选地，所述泄压孔包括圆形孔、腰形孔、方形孔锥形孔中的一个或多个。
在该技术方案中，泄压孔的形状和大小可以任意设置，具体地，泄压孔可为圆形孔、腰形孔、方形孔锥形孔中的一个或多个，因为，这些孔都是比较常见的孔，因而易于加工。
其中，进一步优选地，所述泄压孔为沿着第一刀叶或第二刀叶方向延伸的细长孔，因为第一刀叶和第二刀叶一般因为细长形结构，因而通过将泄压孔设置成细长孔能够使第一刀叶和第二刀叶的结构与泄压孔的形状相适配。
本发明第二方面的实施例提供了一种粉碎刀，用于食物处理机，粉碎刀包括：安装轴，所述安装轴包括安装端和连接端；两个或两个以上刀叶，所述刀叶安装在所述安装轴上，所述刀叶上设置有刀刃；其中，所述两个或两个以上刀叶与所述安装轴形成的两个或两个以上的夹角中至少有两个夹角的角度不相等；所述刀叶的厚度为H，厚度H的值为：1mm≤H≤5mm。
根据本发明的实施例提供的粉碎刀，安装在搅拌器等食物处理机的杯体内，用于对杯体内的水、食材等物料进行粉碎及推送，具体地，粉碎刀包括安装轴和安装在安装轴上的刀叶，其中，刀叶用于对杯体内的物料进行推送及粉碎切割，而安装轴的连接端用于与驱动装置，比如电机驱动连接，以在驱动装置，比如电机的作用下驱动刀叶转动，以对物料进行粉碎及推送，当然，安装轴也可以直接是电机的电机轴。而两个或两个以上刀叶与安装轴形成的两个或两个以上的夹角中至少有两个夹角的角度不相等，即是说两个或两个以上刀叶能够以一定角度安装在安装轴上，且至少有两个刀叶能 够与安装轴形成不同的夹角，这样在工作状态时，就可以使得至少两个刀叶在安装轴的轴向上形成至少两个切割面，即至少两个切割面或其延长面之间形成夹角，至少两个切割面或其延长面之间形成的夹角的角度值为大于0°小于90°，该种设置即能够使粉碎刀的多个刀叶之间在工作状态时形成至少两个不重叠的切割层，从而杯体内的物料被轴向多层切割粉碎，进而能够将物料切割粉碎的更加彻底，以使物料切割粉碎的效果更好、效率更高，因而便能够提供产品的整体品质。其中，将刀叶的厚度H设置在大于等于1mm小于等于5mm的范围内即能够确保刀叶的强度，又能够防止刀叶的厚度过厚。
其中，优选地，所述刀刃与所述刀叶为一体式结构，而刀刃与刀叶为一体式结构能够提高刀刃与刀叶的连接强度，进而能够提高刀叶的抗挤压强度，以使产品经久耐用。
其中，优选地，两个或两个以上刀叶倾斜安装在安装轴上，该种设置能够增大刀叶作用在物料上的面积，进而能够增大刀叶对物料的粉碎切割力，以便能够快速地将物料切割粉碎。
其中，优选地，所述至少一个第二刀叶中至少有一个所述第二刀叶位于一所述第一刀叶靠近所述安装端的一方，即至少有一个第二刀叶位于一第一刀叶的上方，以使第一刀叶和第二刀叶能够形成两层或两层以上设置，以便能够对食材进行分层切割，进而便能够提高粉碎刀对食材的粉碎效率和粉碎效果。
另外，根据本发明上述实施例提供的粉碎刀还具有如下附加技术特征：
在上述技术方案中，优选地，所述刀叶包括：至少一个第一刀叶，所述第一刀叶安装在所述安装轴上，所述第一刀叶上设置有第一刀刃，所述第一刀刃设置在所述第一刀叶远离所述安装端的一面上；至少一个第二刀叶，所述第二刀叶安装在所述安装轴上，所述第二刀叶上设置有第二刀刃，所述第二刀刃设置在所述第二刀叶靠近所述安装端的一面上；其中，所述第一刀叶倾斜安装在所述安装轴上和/或所述第二刀叶倾斜安装在所述安装轴上；所述至少一个第一刀叶与所述安装轴形成的至少一个夹角和所述至少一个第二刀叶与所述安装轴形成的至少一个夹角中至少有两个夹角的角度不相等。
在该技术方案中，刀叶包括第一刀叶和第二刀叶，具体地，第一刀叶和第 二刀叶安装在安装轴的安装端上，安装轴的连接端用于与驱动装置，比如电机驱动连接，以在驱动装置，比如电机的作用下驱动第一刀叶和第二刀叶转动，以对物料进行粉碎及推送，当然，安装轴也可以直接是电机的电机轴，而两个或两个以上第一刀叶上的第一刀刃设置在第一刀叶远离安装端的一面上，即靠近连接端的一面上，也即第一刀刃设置在第一刀叶的下端面上，也即第一刀刃的开口朝下，因此第一刀叶在安装轴的作用下旋转时，便能够边粉碎物料，边将物料向杯体底部及杯体的外侧推送，从而能够使物料从上至下循环运动，而当被推送到的杯体底部的物料越积越多时，先被推送至杯体底部的物料在后被推送至杯体底部的物料的挤压下，便能够顺着杯体的侧壁向上运动，以实现物料从下至上的循环运动，而在物料从下至上运动到杯体的上部时，物料便能够在重力的作用下掉落下来，而后再被第一刀刃粉碎及向下向外推送，至此即可实现物料的一个完整循环，该种循环方式由于物料在第一刀刃的作用下由上至下及由下至下循环运动时，第一刀刃向下推送物料的速度，即物料向下推送速度要快于物料从杯体上部掉落下来的速度，即物料的回流速度，从而会导致杯体中部形成空隙进而形成负压，因此当杯体上部的物料再次回流而补充到该空隙时就会导致物料的波动，进而导致物料的循环翻滚运动不合理，进而使得物料不能够按规定的循环路线和理想的粉碎方位进行运动，而第二刀刃设置在第二刀叶靠近安装端的一面上，即第二刀刃设置在第二刀叶的上端面上，也即第二刀刃的开口朝上，因此，第二刀叶在安装轴的作用下旋转时，便能够边粉碎物料，边将杯体中上部的周边的物料聚集抽取到杯体中上部的中间，然后随着从杯体上部掉落下来的物料一起被第一刀刃粉碎及向下向外推送，从而通过设置第二刀刃，第二刀刃便能够将杯体中上部的周边的物料聚集抽取到杯体中上部的中间，以填补到物料循环过程中形成的空隙内，从而即可消除物料循环过程中形成的缝隙和负压，进而当杯体上部的物料再次回流时，便能够非常平稳地与第二刀刃抽取的物料混合，进而被第一刀刃粉碎并向下推送，因而即可避免物料的波动，以使物料能够按规定的循环路线和理想的粉碎方位进行循环运动，进而一方面便能够对物料进行有效粉碎，以确保物料的加工效率和加工效果，另一方面可减小因物 料波动而对安装轴的冲击，进而使得安装轴能够更为平稳地转动，进而即可减小搅拌器的波动，以使搅拌器平稳地转动，而搅拌器平稳地转动会降低搅拌器的噪音和摩擦生热，进而能够降低搅拌器的温升等。同时，该种设置由于物料循环时没有形成空隙，因而第一刀叶的第一刀刃能够始终作用在物料上，从而便能够提高粉碎刀对物料的粉碎效率，确保粉碎刀对物料的粉碎效果，而通过第二刀叶的第二刀刃的粉碎作用，能够进一步提高粉碎刀对物料的粉碎效率，进而能够进一步确保粉碎刀对物料的粉碎效果。而至少一个第一刀叶与安装轴形成的至少一个夹角和至少一个第二刀叶与安装轴形成的至少一个夹角中至少有两个夹角的角度不相等，即在第一刀叶和第二刀叶均只有一个时，第一刀叶和第二刀叶与安装轴之间的夹角的角度不同，从而使得第一刀叶和第二刀叶能够分两层设置，而在第一刀叶和/或第二刀叶为两个或两个以上时，即可是两个或两个以上第一刀叶中的至少两个与安装轴形成至少两个不同角度的夹角，也可是两个或两个以上第二刀叶中的至少两个与安装轴形成至少两个不同角度的夹角，还可是一个或多个第一刀叶和一个或多个第二刀叶与安装轴形成至少两个不同角度的夹角，也就是说，即可以是至少一个刀叶与至少一个第二刀叶分层设置，也可以是多个第一刀叶之间分层设置，还可以是多个第二刀叶之间分层设置，该种设置即能够使粉碎刀的多个刀叶之间形成至少两个分割层，从而能够对物料进行分层粉碎，进而能够对物料切割粉碎的更加彻底，以使物料切割粉碎的效果更好、效率更高。
其中，优选地，第一刀叶和第二刀叶中至少有一个倾斜设置，即要么第一刀叶倾斜设置，要么第二刀叶倾斜设置，要么第一刀叶和第二刀叶同时倾斜设置，同时，优选地，第一刀叶位于第二刀叶远离安装端的一方，该种设置能够使第一刀叶和第二刀叶形成高度差，因而能够更好地利用位于下方的第一刀叶来将物料向下推送，及更好地利用位于上方的第二刀叶来将物料补充到第一刀叶形成的空隙内。
在上述技术方案中，优选地，所述第一刀刃与所述第一刀叶和/或所述第二刀刃与所述第二刀叶为一体式结构。
在该技术方案中，第一刀刃与第一刀叶和/或第二刀刃与第二刀叶为一体 式结构能够提高第一刀刃与第一刀叶和/或第二刀刃与第二刀叶的连接强度，进而能够提高第一刀叶和第二刀叶的抗挤压强度，以使产品经久耐用。
其中，优选地，所述第一刀叶和所述第二刀叶的厚度为H，厚度H的值为：1mm≤H≤5mm。通过将第一刀叶和第二刀叶的厚度H设置在大于等于1mm小于等于5mm的范围内即能够确保第一刀叶和第二刀叶的强度，又能够防止第一刀叶和第二刀叶的厚度过厚。
在上述技术方案中，优选地，所述第一刀刃设置在所述第一刀叶的一侧上，所述第二刀刃设置在所述第二刀叶的一侧上。
在该技术方案中，可只在第一刀叶和第二刀叶的单侧上设置刀刃，因为，搅拌器在搅拌食物时都是沿同一方向搅拌粉碎食物，因此，在第一刀叶和第二刀叶的单侧上设置刀刃即可满足产品的要求，而只在第一刀叶和第二刀叶的单侧上设置刀刃能够简化第一刀叶和第二刀叶的结构，因而能够简化加工工序，降低加工成本。
在另一技术方案中，优选地，所述至少一个第一刀叶的两侧上均设置有所述第一刀刃，和/或所述至少一个第二刀叶的两侧上均设置有所述第二刀刃。
在该技术方案中，通过在第一刀叶的两侧设置第一刀刃，使得第一刀叶的两侧均能够用于物料粉碎，因而第一刀叶无论是顺时针旋转还是逆时针旋转均能够对物料进行粉碎，进而能够实现第一刀叶的双面粉碎。同理，通过在第二刀叶的两侧均设置第二刀刃，使得第二刀叶的两侧均能够用于物料粉碎，因而第二刀叶无论是顺时针旋转还是逆时针旋转均能够对物料进行粉碎，进而能够实现第二刀叶的双面粉碎。
其中，优选地，所述至少一个第二刀叶中至少有一个所述第二刀叶位于一所述第一刀叶靠近所述安装端的一方，即至少有一个第二刀叶位于一第一刀叶的上方，以使第一刀叶和第二刀叶能够形成两层或两层以上设置，以便能够对物料进行分层切割，进而便能够提高粉碎刀对物料的粉碎效率和粉碎效果。
在上述技术方案中，优选地，所述第二刀叶的一端安装在所述安装轴上，所述第二刀叶的另一端向所述安装端的端部方向倾斜延伸；所述第一刀叶的一端安装在所述安装轴上，所述第一刀叶的另一端向所述连接端的端部方向倾斜 延伸或所述第一刀叶的另一端向所述安装端的端部方向倾斜延伸或所述第一刀叶垂直安装在所述安装轴上。
在该技术方案中，第二刀叶的一端安装在安装轴上，第二刀叶的另一端向安装端的端部方向倾斜延伸，即第二刀叶倾斜向上设置，该种设置由于第二刀叶倾斜向上设置，因此，便能够更高效地将杯体内中上部的物料聚集抽取到第一刀叶形成的空隙内，以使物料流动的更加平稳。而在第二刀叶倾斜向上设置时，第一刀叶即可倾斜向下设置，也可倾斜向上设置，也可垂直于安装轴设置，但优选地，可将第一刀叶倾斜向下设置或倾斜向上设置，而通过将第一刀叶倾斜设置，即非水平设置，使得第一刀叶能够更好地与物料接触，因而能够提高第一刀叶对物料的粉碎及向下向外的推送效果，进而即可提高产品的粉碎效率，确保产品的粉碎效果。其中，具体地，在两个或两个以上第一刀叶呈双层设置时，可将上层的第一刀叶倾斜向上设置，而将下层的第一刀叶倾斜向下设置，以便能够使产品的结构分布的更加合理紧凑。
在上述技术方案中，优选地，所述第一刀叶的数量为偶数个，所述第二刀叶的数量为偶数个。
在该技术方案中，第一刀叶和第二刀叶的数量为偶数个，能够使两两第一刀叶和两两第二刀叶呈对称设置，进而能够使第一刀叶和第二刀叶受到的物料的阻力一致，因而能够使第一刀叶和第二刀叶的受力更加均衡，以防止出现受力薄弱部，进而即能够相对提高第一刀叶和第二刀叶的强度，同时，该种设置能够依次形成四叶刀或八叶刀或十二叶刀等多种规格，进而能够提高粉碎刀的规格。此外中心对称地结构更易加工，因而能够降低产品的加工难度，提高产品的加工效率，降低产品的加工成本。
当然，第一刀叶的数量和第二刀叶的数量也可为奇数个，从而可对应形成三叶刀、五叶刀、七叶刀等多种规格。
在上述技术方案中，优选地，所述第一刀叶的数量为两个或四个或六个；和/或所述第二刀叶的数量为两个或四个。
在该技术方案中，第一刀叶的数量和第二刀叶的数量均为两个时能够形成四叶刀，第二刀叶的数量为两个，而第一刀叶的数量为四个，或第二刀叶的数量为四个，而第一刀叶的数量为两个时能够形成六叶刀，而第二刀叶的数量和 第一刀叶的数量均为四个时能够形成八叶刀，而第二刀叶的数量为两个，第一刀叶的数量为六个时也能够形成八叶刀，此时，优选地，可将四个第一刀叶设置在安装轴的同一横截面上，而将两个第一刀叶和两个第二刀叶相互交替地设置在四个第一刀叶的上面，并位于安装轴的另一横截面上，而该些规格的粉碎刀均能够使物料平稳地循环运动，且该些规格的粉碎刀即能够对物料进行充分粉碎，又能够使得产品的结构较为简单，因而能够在确保粉碎效果的同时，简化产品的结构，降低产品的成本。
在上述技术方案中，优选地，所述第一刀叶的数量为六个，所述第二刀叶的数量为两个；所述六个第一刀叶中的四个第一刀叶安装在所述安装轴的同一横截面上，所述同一横截面为第一横截面，所述六个第一刀叶中的另外两个第一刀叶和所述两个第二刀叶位于所述安装轴的另一同一横截面上，所述另一同一横截面为第二横截面，其中，所述第一横截面位于所述第二横截面靠近所述连接端的一侧。
在该技术方案中，四个第一刀叶安装在安装轴的同一横截面，即第一横截面上，另外两个第一刀叶和两个第二刀叶安装在安装轴的另一同一横截面，即第二横截面上，使得六个第一刀叶和两个第二刀叶形成的八叶刀能够分成上下两层，进而能够对物料进行分层粉碎及分层推送。
在上述技术方案中，优选地，所述第一横截面上的四个所述第一刀叶相互对称，具体地，即可呈中心对称，也可呈轴对称；所述第二横截面上的两个所述第一刀叶相互对称，具体地，即可呈中心对称，也可呈轴对称，所述第二横截面上的两个所述第二刀叶相互对称，具体地，即可呈中心对称，也可呈轴对称。
在该技术方案中，两两第一刀叶和两两第二刀叶呈对称设置，具体地，即可呈中心对称，也可呈轴对称设置，进而能够使第一刀叶和第二刀叶受到的物料的阻力一致，因而能够使第一刀叶和第二刀叶的受力更加均衡，以防止出现受力薄弱部，进而即能够相对提高第一刀叶和第二刀叶的强度，同时，通过将六个第一刀叶和两个第二刀叶两两对称设置，能够使粉碎刀整体呈对称结构，因而一方面能够提高产品的对称美，另一方面还能够使产品的重心居中，因而可提高产品的稳定性，进而可降低产品的波动和噪音。
在上述技术方案中，优选地，所述第一横截面上的四个所述第一刀叶中的两个所述第一刀叶与所述安装轴的横截面之间的夹角在大于等于负45°小于等于0°的范围内，四个所述第一刀叶中的另外两个所述第一刀叶与所述安装轴的横截面之间的夹角在大于等于负20°小于等于正20°的范围内；所述第二横截面上的两个所述第二刀叶与所述安装轴的横截面之间的夹角在大于等于正45°小于等于正70°的范围内，所述第二横截面上的另外两个所述第一刀叶与所述安装轴的横截面之间的夹角在大于等于0°小于等于正45°的范围内。
在该技术方案中，第一刀叶与安装轴的横截面之间的夹角β优选大于等于负45°小于等于正45°的范围内，即第一刀叶在安装轴上即可顺时针向下倾斜0°至45°设置，优选为顺时针向下倾斜10°至20°设置，也可在安装轴上逆时针向上倾斜0°至45°设置，优选为逆时针向上倾斜10°至20°设置，该种设置使得第一刀刃的切割面积和对物料的推送效果比较适中，因而能够在粉碎刀正常安装到杯体内时，使得第一刀叶能够与第二刀叶更好地配合，以更平衡稳定地弥补因第一刀叶的推送而形成的空隙，进而能够使物料平衡稳定地循环运动，反之若角度β太小，则第一刀叶切割面积大，物料排出效果好，因而会导致第一刀叶对物料的排出速度大于第二刀叶对物料的抽取速度，从而会导致物料循环不充分，而若角度β太大，则第一刀叶切割面积小，物料的排出速度慢，从而也会导致第一刀叶对物料的排出速度小于第二刀叶对物料的抽取速度，因而也不能实现物料的平衡，而将夹角β设置在大于等于负45°小于等于正45°的范围内即能够实现物料的排出与抽取的平衡，进而能够使物料平衡稳定地循环运动，以确保物料的粉碎效率和粉碎效果。此外，该种设置将多个第一刀叶以不同角度和/或不同高度地安装在安装轴上，以便能够实现多个第一刀叶的梯级安装，进而能够利用多个第一刀叶实现对物料的梯级粉碎及机梯级推送，因而即能够确保物料的粉碎效率和粉碎效果。而第二刀叶优选在安装轴上逆时针向上倾斜45°至70°设置，该种设置使得第二刀刃的切割面积和对物料的抽取效果比较适中，因而能够在粉碎刀正常安装到杯体内时，使得第二刀叶能够与第一刀叶更好地配合，以更平衡稳定地弥补因第一刀刃的推送而形成的空隙，进而能够使物料平衡稳定地循环运动，具体地，若角度α太小，则第二刀叶切割面积大，抽水效果好，因而会导致第二刀叶对物料的抽取速度大于第一 刀叶对物料的排出速度，从而会导致物料循环不充分，而若角度α太大，则第二刀叶切割面积小，抽水效果差，也会导致第二刀叶对物料的抽取速度小于第一刀叶对物料的排出速度，因而也不能实现物料的平衡，而将夹角α设置在大于等正45°小于等于正70°的范围内，使得第二刀叶对物料的抽取比较适中，因而即能够与第一刀叶更好地配合，以实现物料的排出与抽取的平衡，进而能够使物料平衡稳定地循环运动，以确保物料的粉碎效率和粉碎效果。
其中，在本说明书中，逆时针旋转的角度为正，顺时针旋转的角度为负。
其中，优选地，正50°≤α≤正60°，该种设置能够更好地实现物料的排出与抽取的平衡，进而能够更好地使物料平衡稳定地循环运动，以更好地确保物料的粉碎效率和粉碎效果。
在上述技术方案中，优选地，所述两个第二刀叶的总长度之和与所述六个第一刀叶的总长度之和的比值为A，其中，0.05≤A≤0.8或0.1≤A≤0.4。
在该技术方案中，两个第二刀叶的总长度之和与六个第一刀叶的总长度之和的比值A，即所有第二刀叶的长度之和与所有第一刀叶的长度之和的比值A不宜过大也不宜过小，具体地，若A值过小，则第二刀叶的对物料的抽取聚集效率低，从而导致第二刀叶无法填补第一刀叶形成的空隙，从而会导致物料的循环的效率低，因而会造成物料的粉碎效果差，但若A值过大，则第二刀叶的对物料的抽取聚集效率偏高，从而导致第一刀叶无法及时将中部的物料排出至杯体的底部，进而会造成物料推挤，因而也会导致物料的循环的效率低，从而会造成物料的粉碎效果差，而通过将比值A设置在大于等于0.05小于等于0.8的范围内，即能够确保杯体内物料的循环平衡稳定，又能够提高粉碎效果和粉碎效率，进而会提高产品的整体品质。
其中，优选地，0.1≤A≤0.4，即比值A的值优选设置在大于等于0.1小于等于0.4的范围内，该种设置，能够使物料的循环达到最佳的平衡状态，因而能够进一步提高粉碎效果和粉碎效率，以进一步提高产品的整体品质。
在上述技术方案中，优选地，粉碎刀还包括：第一刀根部，所述第一刀 根部套设安装在所述安装轴上；第二刀根部，所述第二刀根部套设安装在所述安装轴上，并位于所述第一刀根部靠近所述安装端的一方；其中，所述至少一个第一刀叶设置在所述第一刀根部上或所述至少一个第一刀叶设置在所述第一刀根部和所述第二刀根部上；所述至少一个第二刀叶设置在所述第二刀根部上。

此外，还可设置第三刀根部或第四刀根部等，以便能够将两个或两个以上第一刀叶安装成多层，或者将两个或两个以上第二刀叶安装成多层，以便能够将产品设计成三层刀叶、四层刀叶或更多层刀叶的结构。

在该技术方案中，可优选将第一刀叶和第二刀叶与对应的刀根部，即第一刀根部和第二刀根部设置为一体式结构，因为，一体式结构的力学性能好，因而能够确保刀根部和刀叶之间的连接强度，其中，优选地，可将刀叶和刀根部一体制成，批量生产，以提高产品的加工效率，降低产品的加工成本。具体地，可利用同一金属板折弯出第一刀叶、第二刀叶和对应的刀根部，以方便、快速且低成本地实现第二刀和第一刀叶的加工。
在上述技术方案中，优选地，所述第一刀根部与所述第二刀根部为一 体式结构。
在该技术方案中，可优选将第一刀根部与第二刀根部设置为一体式结构，因为，一体式结构的力学性能好，因而能够确保第一刀根部与第二刀根部之间的连接强度，其中，优选地，可将第一刀根部与第二刀根部一体制成，批量生产，以提高产品的加工效率，降低产品的加工成本。
当然，在另一技术方案中，第一刀根部与第二刀根部也可为分体式结构，此时，便于将第一刀根部和第二刀根部与对应的刀叶一体制成、批量生产。
在上述技术方案中，优选地，所述第一刀根部上设置有第一通孔，所述第二刀根部上设置有第二通孔，所述第一刀根部通过所述第一通孔套设安装在所述安装轴上，所述第二刀根部通过所述第二通孔套设安装在所述安装轴上。

当然，在另一技术方案中，也可利用安装轴和第一通孔和第二通孔的过盈配合实现第一刀根部和第二刀根部与安装轴之间的安装。
在上述技术方案中，优选地，所述第一刀根部贴合在所述第二刀根部上。
在该技术方案中，第一刀根部贴合在第二刀根部上，因此能够使第一刀叶和第二刀叶形成一个整体而进行同步旋转，因而能够使第一刀叶和第二刀叶对物料进行同步粉碎，进而能够使第一刀叶和第二刀叶更好地同步配合，以提高对物料的粉碎效率，同时，第一刀根部贴合在第二刀根部上还能够使得第一刀根部和第二刀根部相互支撑，进而能够提高第一刀根部和第二刀根部的强度，此外，该种设置还能够使粉碎刀的结构更为紧凑合理，因而能够减小产品的整体体积。还有该种设置能够防止第一刀根部和第二刀根部之间形成狭窄缝隙，进而更利于用户对粉碎刀进行清洗。
在上述技术方案中，优选地，所述第一刀根部和所述第二刀根部的形状大小一致。
在该技术方案中，第一刀根部和第二刀根部的形状大小一致，一方面能够使第一刀叶和第二刀叶的强度一致，另一方面能够提高减少零部件的类型，以利于产品的标准化。当然，在另一技术方案中，第一刀根部和第二刀根部的形状大小也可不一致。
在上述技术方案中，优选地，所述第一刀根部和/或所述第二刀根部为方形、圆形，三角形，椭圆形或五边形，具体地，第一刀根部和/或第二刀根部的形状可根据第一刀叶和第二刀叶的数量变化而变化。
在该技术方案中，第一刀根部和/或第二刀根部优选为方形，因为方形相比于圆形、椭圆形而言更易加工，因而能够降低产品的加工成本，提高产品的加工效率。具体地比如，该种结构使得第一刀叶和第二刀叶能够通过金属板快速简单地折弯形成，而圆形则无法通过金属板直接折弯形成。当然，也可为圆形，三角形，椭圆形，五边形或者任意其它形状。
在上述技术方案中，优选地，所述第一刀根部与所述安装轴相互垂直安装，所述第二刀根部与所述安装轴相互垂直安装。
在该技术方案中，第一刀根部与安装轴相互垂直安装，第二刀根部与安装轴相互垂直安装能够使第一刀根部和第二刀根部之间安装的更加牢靠，因而能够使第一刀叶和第二刀叶在粉碎物料时不会与安装轴脱落，从而即可防止第一刀叶和第二刀叶脱落伤人，进而即可确保用户的使用安全。具体地，可将第二刀叶与第二刀根部之间呈一角度设置，以确保第二刀根 部与安装轴相互垂直安装时，刀叶能够向上倾斜设置，同时，可使第一刀叶与第一刀根部之间呈一角度设置，以确保第一刀根部与安装轴相互垂直安装时，第一刀叶能够向下倾斜设置。
在上述技术方案中，优选地，所述安装轴为圆形轴。
在该技术方案中，安装轴优选为圆形轴，因为圆形轴更易与电机等配合，从而能够更利于对安装轴进行驱动。
在上述技术方案中，优选地，第一刀叶和/或第二刀叶由金属材料制成，因为，金属材料的强度高，耐磨性好，因而能够更好地粉碎物料。当然，第二刀叶和/或第一刀叶也可为其它硬度比较高的材料制成。
在上述技术方案中，优选地，所述第一刀叶远离所述安装轴的一端上设置有压板。
在该技术方案中，通过在第一刀叶远离安装轴的一端(即第一刀叶的尾部)上设置压板，从而能够通过压板来向将物料推送至杯体底部，而压板的设置能够增大第一刀叶与物料的接触面积，因而能够增大第一刀叶对物料的推力，进而能够加快物料的循环速度，因而能够提高产品的粉碎效率。
在上述技术方案中，优选地，所述压板与所述第一刀叶之间的角度为γ，其中，夹角γ的值为：90°<γ≤180°，或夹角γ的值为：135°≤γ≤180°，或夹角γ的值为160°≤γ≤170°，其中，优选地，135°≤γ≤180°。
在该技术方案中，通过将压板与第一刀叶之间的夹角设置在大于等于135°小于等于180°的范围内，能够确保第一刀叶向下向外侧的压水作用，以便能够使物料的内外循环快速，顺畅，同时该种设置还能够加大第一刀叶的切割投影面积，因而能最大限度的提高粉碎效果和粉碎效率。
其中，进一步优选地，夹角γ的值为：160°≤γ≤170°。
在上述技术方案中，优选地，粉碎刀还包括：泄压孔，设置在所述刀叶上，具体地，比如设置在所述第一刀叶上和/或所述第二刀叶上。
在该技术方案中，通过设置泄压孔能够在第一刀叶和/或第二刀叶推送物料时为第一刀叶和/或第二刀叶泄压，以防止第一刀叶和/或第二刀叶因压力过大而折断，具体地，比如，在第一刀叶将物料推送至杯体底部时，若 杯体底部的物料聚集的过多，则物料对第一刀叶的阻力较大，而通过设置泄压孔可利用物料与第一刀叶之间的挤压，以使物料能够从泄压孔内排出，从而对第一刀叶起到泄压的作用，进而即可使第一刀叶经久耐用而不易折断，因而即可延长产品的使用寿命，同理，在第二刀叶抽取物料时，若抽取的物料过多，则物料对第二刀叶的阻力较大，而通过设置泄压孔可利用物料与第二刀叶之间的挤压，以使物料能够从泄压孔内排出，从而对第二刀叶起到泄压的作用，进而即可使第二刀叶经久耐用而不易折断，因而也可延长产品的使用寿命。当然，我们也可只在第一刀叶上设置泄压孔，而不在第二刀叶上设置泄压孔。
在上述技术方案中，优选地，所述至少一个第一刀叶上均设置有所述泄压孔，且所述至少一个第一刀叶上设置的所述泄压孔的形状大小一致。
在该技术方案中，可将第一刀叶上均设置上泄压孔，从而能够对所有的第一刀叶进行泄压，以大幅度提高粉碎刀的整体抗压能力，而一个或两个或两个以上第一刀叶上的泄压孔的形状大小一致使得每个第一刀叶的泄压能力一样，进而能够使每个第一刀叶对物料的推送效果一致，进而即可使杯体的内的物料平稳地运动，以防止物料波动。当然，也可只在部分第一刀叶上设置泄压孔，而在其余部分的第一刀叶上不设置泄压孔。
在上述技术方案中，优选地，所述泄压孔包括圆形孔、腰形孔、方形孔锥形孔中的一个或多个。
在该技术方案中，泄压孔的形状和大小可以任意设置，具体地，泄压孔可为圆形孔、腰形孔、方形孔锥形孔中的一个或多个，因为，这些孔都是比较常见的孔，因而易于加工。
其中，进一步优选地，所述泄压孔为沿着第一刀叶或第二刀叶方向延伸的细长孔，因为第一刀叶和第二刀叶一般因为细长形结构，因而通过将泄压孔设置成细长孔能够使第一刀叶和第二刀叶的结构与泄压孔的形状相适配。

具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图13来描述根据本发明的一个实施例提供的粉碎刀100及食物处理机200。
如图1至图12所示，本发明第一方面的实施例提供了一种粉碎刀100，用于食物处理机200，包括：安装轴1，安装轴1包括安装端和连接端；至少一个第一刀叶2，第一刀叶2安装在安装轴1上，第一刀叶2上设置有第一刀刃22，第一刀刃22设置在第一刀叶2远离安装端的一面上；至少一个第二刀叶3，第二刀叶3安装在安装轴1上，第二刀叶3上设置有第二刀刃32，第二刀刃32设置在第二刀叶3靠近安装端的一面上；其中，第一刀叶2倾斜安装在安装轴1上和/或第二刀叶3倾斜安装在安装轴1上，第一刀叶2和第二刀叶3的厚度为H，厚度H的值为：1mm≤H≤5mm。
根据本发明的实施例提供的粉碎刀100，安装在搅拌器等食物处理机200的杯体内，用于对杯体内的物料进行粉碎及推送，具体地，安装轴1的安装端用于安装第一刀叶2和第二刀叶3，安装轴1的连接端用于与驱动装置，比如电机驱动连接，以在驱动装置，比如电机的作用下驱动第一刀叶2和第二刀叶3转动，以对物料进行粉碎及推送，当然，安装轴1也可以直接是电机的电机轴，而两个或两个以上第一刀叶2上的第一刀刃22设置在第一刀叶2远离安装端的一面上，即靠近连接端的一面上，也即第一刀刃22设置在第一刀叶2的下端面上，也即第一刀刃22的开口朝下，因此第一刀叶2在安装轴1的作用下旋转时，便能够边粉碎物料，边将物料向杯体底部及杯体的外侧推送，从而能够使物料从上至下循环运动，而当被推送到的杯体底部的物料越积越多时，先被推送至杯体底部的物料在 后被推送至杯体底部的物料的挤压下，便能够顺着杯体的侧壁向上运动，以实现物料从下至上的循环运动，而在物料从下至上运动到杯体的上部时，物料便能够在重力的作用下掉落下来，而后再被第一刀刃22粉碎及向下向外推送，至此即可实现物料的一个完整循环，该种循环方式由于物料在第一刀刃22的作用下由上至下及由下至下循环运动时，第一刀刃22向下推送物料的速度，即物料向下推送速度要快于物料从杯体上部掉落下来的速度，即物料的回流速度，从而会导致杯体中部形成空隙进而形成负压，因此当杯体上部的物料再次回流而补充到该空隙时就会导致物料的波动，进而导致物料的循环翻滚运动不合理，进而使得物料不能够按规定的循环路线和理想的粉碎方位进行运动，而第二刀刃32设置在第二刀叶3靠近安装端的一面上，即第二刀刃32设置在第二刀叶3的上端面上，也即第二刀刃32的开口朝上，因此，第二刀叶3在安装轴1的作用下旋转时，便能够边粉碎物料，边将杯体中上部的周边的物料聚集抽取到杯体中上部的中间，然后随着从杯体上部掉落下来的物料一起被第一刀刃22粉碎及向下向外推送，从而通过设置第二刀刃32，第二刀刃32便能够将杯体中上部的周边的物料聚集抽取到杯体中上部的中间，以填补到物料循环过程中形成的空隙内，从而即可消除物料循环过程中形成的缝隙和负压，进而当杯体上部的物料再次回流时，便能够非常平稳地与第二刀刃32抽取的物料混合，进而被第一刀刃22粉碎并向下推送，因而即可避免物料的波动，以使物料能够按规定的循环路线和理想的粉碎方位进行循环运动，进而一方面便能够对物料进行有效粉碎，以确保物料的加工效率和加工效果，另一方面可减小因物料波动而对安装轴1的冲击，进而使得安装轴1能够更为平稳地转动，进而即可减小搅拌器的波动，以使搅拌器平稳地转动，而搅拌器平稳地转动会降低搅拌器的噪音和摩擦生热，进而能够降低搅拌器的温升等。同时，该种设置由于物料循环时没有形成空隙，因而第一刀叶2的第一刀刃22能够始终作用在物料上，从而便能够提高粉碎刀100对物料的粉碎效率，确保粉碎刀100对物料的粉碎效果，而通过第二刀叶3的第二刀刃32的粉碎作用，能够进一步提高粉碎刀100对物料的粉碎效率，进而能够进一步确保粉碎刀100对物料的粉碎效果。其中，将第一刀叶2和第 二刀叶3的厚度H设置在大于等于1mm小于等于5mm的范围内即能够确保第一刀叶2和第二刀叶3的强度，又能够防止第一刀叶2和第二刀叶3的厚度过厚。
其中，优选地，如图1至图12所示，第一刀叶2和第二刀叶3中至少有一个倾斜设置，即要么第一刀叶2倾斜设置，要么第二刀叶3倾斜设置，要么第一刀叶2和第二刀叶3同时倾斜设置，同时，优选地，第一刀叶2位于第二刀叶3远离安装端的一方，该种设置能够使第一刀叶2和第二刀叶3形成高度差，因而能够更好地利用位于下方的第一刀叶2来将物料向下推送，及更好地利用位于上方的第二刀叶3来将物料补充到第一刀叶2形成的空隙内。
在上述实施例中，优选地，如图1至图12所示，第一刀刃22与第一刀叶2和/或第二刀刃32与第二刀叶3为一体式结构。
在该实施例中，第一刀刃22与第一刀叶2和/或第二刀刃32与第二刀叶3为一体式结构能够提高第一刀刃22与第一刀叶2和/或第二刀刃32与第二刀叶3的连接强度，进而能够提高第一刀叶2和第二刀叶3的抗挤压强度，以使产品经久耐用。
在上述实施例中，优选地，如图1至图12所示，第一刀刃22设置在第一刀叶2的一侧上，第二刀刃32设置在第二刀叶3的一侧上。
在该实施例中，可只在第一刀叶2和第二刀叶3的单侧上设置刀刃，因为，搅拌器在搅拌食物时都是沿同一方向搅拌粉碎食物，因此，在第一刀叶2和第二刀叶3的单侧上设置刀刃即可满足产品的要求，而只在第一刀叶2和第二刀叶3的单侧上设置刀刃能够简化第一刀叶2和第二刀叶3的结构，因而能够简化加工工序，降低加工成本。
在另一实施例中，优选地，至少一个第一刀叶2的两侧上均设置有第一刀刃22，和/或至少一个第二刀叶3的两侧上均设置有第二刀刃32。
在该实施例中，通过在第一刀叶2的两侧设置第一刀刃22，使得第一刀叶2的两侧均能够用于物料粉碎，因而第一刀叶2无论是顺时针旋转还是逆时针旋转均能够对物料进行粉碎，进而能够实现第一刀叶2的双面粉碎。同理，通过在第二刀叶3的两侧均设置第二刀刃32，使得第二刀叶3 的两侧均能够用于物料粉碎，因而第二刀叶3无论是顺时针旋转还是逆时针旋转均能够对物料进行粉碎，进而能够实现第二刀叶3的双面粉碎。
其中，优选地，如图1至图10所示，至少一个第二刀叶3中至少有一个第二刀叶3位于一第一刀叶2靠近安装端的一方，即至少有一个第二刀叶3位于一第一刀叶2的上方，以使第一刀叶2和第二刀叶3能够形成两层或两层以上设置，以便能够对食材进行分层切割，进而便能够提高粉碎刀对食材的粉碎效率和粉碎效果。
在上述实施例中，优选地，第二刀叶3的一端安装在安装轴1上，第二刀叶3的另一端向安装端的端部方向倾斜延伸；第一刀叶2的一端安装在安装轴1上，第一刀叶2的另一端向连接端的端部方向倾斜延伸或第一刀叶2的另一端向安装端的端部方向倾斜延伸或第一刀叶2垂直安装在安装轴1上。
在该实施例中，第二刀叶3的一端安装在安装轴1上，第二刀叶3的另一端向安装端的端部方向倾斜延伸，即第二刀叶3倾斜向上设置，该种设置由于第二刀叶3倾斜向上设置，因此，便能够更高效地将杯体内中上部的食材聚集抽取到第一刀叶2形成的空隙内，以使食材流动的更加平稳。而在第二刀叶3倾斜向上设置时，第一刀叶2即可倾斜向下设置，也可倾斜向上设置，也可垂直于安装轴1设置，但优选地，可将第一刀叶2倾斜向下设置或倾斜向上设置，而通过将第一刀叶2倾斜设置，即非水平设置，使得第一刀叶2能够更好地与物料接触，因而能够提高第一刀叶2对物料的粉碎及向下向外的推送效果，进而即可提高产品的粉碎效率，确保产品的粉碎效果。其中，具体地，在两个或两个以上第一刀叶2呈双层设置时，可将上层的第一刀叶2倾斜向上设置，而将下层的第一刀叶2倾斜向下设置，以便能够使产品的结构分布的更加合理紧凑。
在上述实施例中，优选地，如图1至图12所示，第一刀叶2的数量为两个或两个以上，两个或两个以上第一刀叶2对称地安装在安装轴1上，或两个或两个以上第一刀叶2沿安装轴1的周向均匀分布。
在该实施例中，第一刀叶2的数量为两个或两个以上，因而能够通过两个或两个以上第一刀叶2同时粉碎物料及同时将物料向杯体底部及杯体 外侧推送，进而能够加大第一刀叶2对物料的粉碎力度及加快物料的循环速度，因而即能够提高产品的粉碎效率，又能够确保产品的粉碎效果。而两个或两个以上第一刀叶2对称设置或均匀分布在安装轴1的周向上，能够使第一刀叶2对各个角度上的食材的推送及粉碎的效果一致，因而能够实现对食材的均匀粉碎及均匀推送，因而能够使杯体内的各个角度上的食材流动的更加顺畅、平稳。
在上述实施例中，优选地，如图1至图12所示，第二刀叶3的数量为两个或两个以上，两个或两个以上第二刀叶3对称地安装在安装轴1上，或两个或两个以上第二刀叶3沿安装轴1的周向均匀分布。
在该实施例中，第二刀叶3的数量为两个或两个以上，因而能够通过两个或两个以上第二刀叶3同时粉碎物料及同时将杯体中上部的周边的物料聚集抽取到杯体中上部的中间，进而能够加大第二刀叶3同时对物料的粉碎效果及对周边物料的聚集抽取效果，因而能够将更多的物料填补到物料循环过程中形成的空隙内，进而能够进一步减小物料的波动及物料对转动轴的冲击，以使产品能够更加平稳、低噪音、低温升、高效率地运行。而两个或两个以上第二刀叶3对称设置或均匀分布在安装轴1的周向上，能够使第二刀叶3对各个角度上的食材的聚集抽取的效果一致，因而能够使杯体内的各个角度上的食材流动的更加顺畅、平稳。
在上述实施例中，优选地，如图3至图12所示，第一刀叶2的数量为两个或两个以上，两个或两个以上第一刀叶2沿安装轴1的轴向呈两层或两层以上分布。
在该实施例中，可设置两个或两个以上第一刀叶2并使两个或两个以上第一刀叶2在安装轴1上分层，即两层或两层以上设置，从而便能够对物料进行分层粉碎及分层向下向外推送，进而即能够提高第一刀叶2对物料的粉碎及推送效果，以提高产品的粉碎效率，确保产品的粉碎效果。
在上述实施例中，优选地，如图1至图12所示，第一刀叶2的数量为偶数个，第二刀叶3的数量为偶数个。
在该实施例中，第一刀叶2和第二刀叶3的数量为偶数个，能够使两两第一刀叶2和两两第二刀叶3呈对称设置，进而能够使第一刀叶2和第 二刀叶3受到的物料的阻力一致，因而能够使第一刀叶2和第二刀叶3的受力更加均衡，以防止出现受力薄弱部，进而即能够相对提高第一刀叶2和第二刀叶3的强度，同时，该种设置能够依次形成四叶刀或八叶刀或十二叶刀等多种规格，进而能够提高粉碎刀100的规格。此外中心对称地结构更易加工，因而能够降低产品的加工难度，提高产品的加工效率，降低产品的加工成本。
当然，第一刀叶2的数量和第二刀叶3的数量也可为奇数个，从而可对应形成三叶刀、五叶刀、七叶刀等多种规格。
在上述实施例中，优选地，如图1和图2所示，第一刀叶2的数量为两个或如图3和图4所示，第一刀叶2的数量为四个，或如图5至图10所示，第一刀叶2的数量为六个；和/或如图1至图10所示，第二刀叶3的数量为两个，当然第二刀叶3的数量也可为四个。
在该实施例中，如图1和图2所示，第一刀叶2的数量和第二刀叶3的数量均为两个时能够形成四叶刀，如图3和图4所示，第二刀叶3的数量为两个，而第一刀叶2的数量为四个，或第二刀叶3的数量为四个，而第一刀叶2的数量为两个时能够形成六叶刀，而第二刀叶3的数量和第一刀叶2的数量均为四个时能够形成八叶刀，而如图5至图10所示，第二刀叶3的数量为两个，第一刀叶2的数量为六个时也能够形成八叶刀，此时，优选地，可如图5至图10所示，将四个第一刀叶2设置在安装轴1的同一横截面上，而将两个第一刀叶2和两个第二刀叶3相互交替地设置在四个第一刀叶2的上面，并位于安装轴1的另一横截面上，而该些规格的粉碎刀100均能够使物料平稳地循环运动，且该些规格的粉碎刀100即能够对物料进行充分粉碎，又能够使得产品的结构较为简单，因而能够在确保粉碎效果的同时，简化产品的结构，降低产品的成本。
在上述实施例中，优选地，如图1至图10所示，粉碎刀100还包括：第一刀根部4，第一刀根部4套设安装在安装轴1上；第二刀根部5，第二刀根部5套设安装在安装轴1上，并位于第一刀根部4靠近安装端的一方；其中，至少一个第一刀叶2设置在第一刀根部4上或至少一个第一刀叶2设置在第一刀根部4和第二刀根部5上；至少一个第二刀叶3设置在第二 刀根部5上。
在该实施例中，可在安装轴1上设置两个刀根部，即第一刀根部4和第二刀根部5，从而能够将至少一个第一刀叶2和至少一个第二刀叶3安装在第一刀根部4或第二刀根部5上，以使粉碎刀100形成双层结构，其中，具体地，在第一刀叶2的数量和第二刀叶3的数量相等时，可将所有的第一刀叶2全部安装在下层，即第一刀根部4上，同时将所有的第二刀叶3全部安装在上层，即第二刀根部5上，而在第一刀叶2的数量比第二刀叶3的数量多时，可将大部分第一刀叶2安装在下层，即第一刀根部4上，而将剩下的第一刀叶2与所有的第二刀叶3交替对称地安装在上层，即第二刀根部5上，此时，优选地，将第二刀根部5上的第一刀叶2倾斜向上设置，以使其倾斜方向能够与第二刀叶3的倾斜方向一致，从而即可确保产品的美观性和对称性。
此外，还可设置第三刀根部或第四刀根部等，以便能够将两个或两个以上第一刀叶2安装成多层，或者将两个或两个以上第二刀叶3安装成多层，以便能够将产品设计成三层刀叶、四层刀叶或更多层刀叶的结构。
在上述实施例中，优选地，如图1至图10所示，至少一个第一刀叶2均设置在第一刀根部4上时，第一刀根部4与第一刀叶2为一体式结构，在第二刀根部5上也设置有第一刀叶2时，第二刀根部5与第一刀叶2为一体式结构；和/或第二刀根部5与至少一个第二刀叶3为一体式结构。
在该实施例中，可优选将第一刀叶2和第二刀叶3与对应的刀根部，即第一刀根部4和第二刀根部5设置为一体式结构，因为，一体式结构的力学性能好，因而能够确保刀根部和刀叶之间的连接强度，其中，优选地，可将刀叶和刀根部一体制成，批量生产，以提高产品的加工效率，降低产品的加工成本。具体地，可利用同一金属板折弯出第一刀叶2、第二刀叶3和对应的刀根部，以方便、快速且低成本地实现第二刀和第一刀叶2的加工。
在上述实施例中，优选地，第一刀根部4与第二刀根部5为一体式结构。
在该实施例中，可优选将第一刀根部4与第二刀根部5设置为一体式 结构，因为，一体式结构的力学性能好，因而能够确保第一刀根部4与第二刀根部5之间的连接强度，其中，优选地，可将第一刀根部4与第二刀根部5一体制成，批量生产，以提高产品的加工效率，降低产品的加工成本。
当然，在另一实施例中，第一刀根部4与第二刀根部5也可为分体式结构，此时，便于将第一刀根部4和第二刀根部5与对应的刀叶一体制成、批量生产。
在上述实施例中，优选地，如图1至图10所示，第一刀根部4上设置有第一通孔42，第二刀根部5上设置有第二通孔52，第一刀根部4通过第一通孔42套设安装在安装轴1上，第二刀根部5通过第二通孔52套设安装在安装轴1上。
在该实施例中，可在第一刀根部4上设置第一通孔42，而在第二刀根部5上设置第二通孔52，从而可将安装轴1的安装端依次穿过第一通孔42和第二通孔52，以实现第一刀叶2和第二刀叶3的精确安装。
在上述实施例中，优选地，安装轴1的安装端上设置有环形安装槽12，第一刀根部4通过第一通孔42与环形安装槽12的配合套设安装在安装轴1上，第二刀根部5通过第二通孔52与环形安装槽12的配合套设安装在安装轴1上；其中，安装端的端部上设置有压边，压边压合在第二刀根部5上。
在该实施例中，通过设置环形安装槽12能够利用环形安装槽12来对第一刀根部4和第二刀根部5进行定位安装，具体地，可将安装轴1的安装端依次穿过第一通孔42和第二通孔52，然后将第一刀根部4和第二刀根部5卡在环形安装槽12内，以利用环形安装槽12实现对第一刀根部4和第二刀根部5的卡扣安装。同时，在第一刀根部4和第二刀根部5套设安装在安装轴1上的环形安装槽12上后，可将安装轴1伸出第二刀根部5的部分压平后压合在第二刀根部5上，以便能够简单快速地实现第二刀根部5和第一刀跟与安装轴1之简的固定及安装。
当然，在另一实施例中，也可利用安装轴1和第一通孔42和第二通孔52的过盈配合实现第一刀根部4和第二刀根部5与安装轴1之间的安装。
在上述实施例中，优选地，如图1、图3和图5所示，第一刀根部4贴合在第二刀根部5上。
在该实施例中，第一刀根部4贴合在第二刀根部5上，因此能够使第一刀叶2和第二刀叶3形成一个整体而进行同步旋转，因而能够使第一刀叶2和第二刀叶3对物料进行同步粉碎，进而能够使第一刀叶2和第二刀叶3更好地同步配合，以提高对物料的粉碎效率，同时，第一刀根部4贴合在第二刀根部5上还能够使得第一刀根部4和第二刀根部5相互支撑，进而能够提高第一刀根部4和第二刀根部5的强度，此外，该种设置还能够使粉碎刀100的结构更为紧凑合理，因而能够减小产品的整体体积。还有该种设置能够防止第一刀根部4和第二刀根部5之间形成狭窄缝隙，进而更利于用户对粉碎刀100进行清洗。
在上述实施例中，优选地，如图2、图4和图12所示，第一刀根部4和第二刀根部5的形状大小一致。
在该实施例中，第一刀根部4和第二刀根部5的形状大小一致，一方面能够使第一刀叶2和第二刀叶3的强度一致，另一方面能够提高减少零部件的类型，以利于产品的标准化。当然，在另一实施例中，第一刀根部4和第二刀根部5的形状大小也可不一致。
在上述实施例中，优选地，如图2、图4和图12所示，第一刀根部4和/或第二刀根部5为方形，当然，第一刀根部4也可为圆形，三角形，椭圆形或五边形，具体地，第一刀根部4和/或第二刀根部5的形状可根据第一刀叶2和第二刀叶3的数量变化而变化。
在该实施例中，第一刀根部4和/或第二刀根部5优选为方形，因为方形相比于圆形、椭圆形而言更易加工，因而能够降低产品的加工成本，提高产品的加工效率。具体地比如，该种结构使得第一刀叶2和第二刀叶3能够通过金属板快速简单地折弯形成，而圆形则无法通过金属板直接折弯形成。当然，也可为圆形，三角形，椭圆形，五边形或者任意其它形状。
在上述实施例中，优选地，如图1至图12所示，第一刀根部4与安装轴1相互垂直安装，第二刀根部5与安装轴1相互垂直安装。
在该实施例中，第一刀根部4与安装轴1相互垂直安装，第二刀根部 5与安装轴1相互垂直安装能够使第一刀根部4和第二刀根部5之间安装的更加牢靠，因而能够使第一刀叶2和第二刀叶3在粉碎物料时不会与安装轴1脱落，从而即可防止第一刀叶2和第二刀叶3脱落伤人，进而即可确保用户的使用安全。具体地，可将第二刀叶3与第二刀根部5之间呈一角度设置，以确保第二刀根部5与安装轴1相互垂直安装时，刀叶能够向上倾斜设置，同时，可使第一片与第一刀根部4之间呈一角度设置，以确保第一刀根部4与安装轴1相互垂直安装时，第一刀叶2能够向下倾斜设置。
在上述实施例中，优选地，如图1至图12所示，安装轴1为圆形轴。
在该实施例中，安装轴1优选为圆形轴，因为圆形轴更易与电机等配合，从而能够更利于对安装轴1进行驱动。
在上述实施例中，优选地，第一刀叶2和/或第二刀叶3由金属材料制成，因为，金属材料的强度高，耐磨性好，因而能够更好地粉碎物料。当然，第二刀叶3和/或第一刀叶2也可为其它硬度比较高的材料制成。
在上述实施例中，优选地，如图1、图3和图5所示，第一刀叶2远离安装轴1的一端上设置有压板24。
在该实施例中，通过在第一刀叶2远离安装轴1的一端(即第一刀叶2的尾部)上设置压板24，从而能够通过压板24来向将物料推送至杯体底部，而压板24的设置能够增大第一刀叶2与物料的接触面积，因而能够增大第一刀叶2对物料的推力，进而能够加快物料的循环速度，因而能够提高产品的粉碎效率。
在上述实施例中，优选地，如图12所示，压板24与第一刀叶2之间的角度为γ，其中，夹角γ的值为：90°<γ≤180°，进一步优选地，135°≤γ≤180°。
在该实施例中，通过将压板24与第一刀叶2之间的夹角设置在大于等于135°小于等于180°的范围内，能够确保第一刀叶2向下向外侧的压水作用，以便能够使物料的内外循环快速，顺畅，同时该种设置还能够加大第一刀叶2的切割投影面积，因而能最大限度的提高粉碎效果和粉碎效率。
其中，进一步优选地，夹角γ的值为：160°≤γ≤170°。
在上述实施例中，优选地，如图11所示，至少一个第二刀叶3的总长 度之和与至少一个第一刀叶2的总长度之和的比值为A，其中，0.05≤A≤0.8。
在该实施例中，至少一个第二刀叶3的总长度之和与至少一个第一刀叶2的总长度之和的比值A，即所有第二刀叶3的总长度之和与所有第一刀叶2的总长度之和的比值A不宜过大也不宜过小，具体地，若A值过小，则第二刀叶3的对物料的抽取聚集效率低，从而导致第二刀叶3无法填补第一刀叶2形成的空隙，从而会导致物料的循环的效率低，因而会造成物料的粉碎效果差，但若A值过大，则第二刀叶3对物料的抽取聚集效率偏高，从而导致第一刀叶2无法及时将中部的物料排出至杯体的底部，进而会造成物料推挤，因而也会导致物料的循环的效率低，从而会造成物料的粉碎效果差，而通过将比值A设置在大于等于0.05小于等于0.8的范围内，即能够确保杯体内物料的循环平衡稳定，又能够提高物料的粉碎效果和粉碎效率，进而会提高产品的整体品质。
其中，优选地，0.1≤A≤0.4，即比值A的值优选设置在大于等于0.1小于等于0.4的范围内，该种设置，能够使物料的循环达到最佳的平衡状态，因而能够进一步提高物料的粉碎效果和粉碎效率，以进一步提高产品的整体品质。
在上述实施例中，优选地，第二刀叶3与安装轴1的横截面之间的夹角为α，其中，夹角α的值为：正45°≤α≤正70°。
在该实施例中，第二刀叶3与安装轴1的横截面即水平面之间的夹角α优选在大于等正45°小于等于正70°的范围内，即第二刀叶3优选在安装轴1上逆时针向上倾斜45°至70°设置，该种设置使得第二刀刃32的切割面积和对物料的抽取效果比较适中，因而能够在粉碎刀100正常安装到杯体内时，使得第二刀叶3能够与第一刀叶2更好地配合，以更平衡稳定地弥补因第一刀刃22的推送而形成的空隙，进而能够使物料平衡稳定地循环运动，反之若角度α太小，则第二刀叶3切割面积大，抽水效果好，因而会导致第二刀叶3对物料的抽取速度大于第一刀叶2对物料的排出速度，从而会导致物料循环不充分，而若角度α太大，则第二刀叶3切割面积小，抽水效果差，也会导致第二刀叶3对物料的抽取速度小于第一刀叶 2对物料的排出速度，因而也不能实现物料的平衡，而将夹角α设置在大于等正45°小于等于正70°的范围内，使得第二刀叶3对物料的抽取比较适中，因而即能够与第一刀叶2更好地配合，以实现物料的排出与抽取的平衡，进而能够使物料平衡稳定地循环运动，以确保物料的粉碎效率和粉碎效果。
其中，在本说明书中，逆时针旋转的角度为正，顺时针旋转的角度为负。
其中，优选地，正50°≤α≤正60°，该种设置能够更好地实现物料的排出与抽取的平衡，进而能够更好地使物料平衡稳定地循环运动，以更好地确保物料的粉碎效率和粉碎效果。
在上述实施例中，优选地，如图11和图12所示，第一刀叶2与安装轴1的横截面之间的夹角为β，其中夹角β的值为：负45°≤β≤正45°。
在该实施例中，第一刀叶2与安装轴1的横截面之间的夹角β优选大于等于负45°小于等于正45°的范围内，即第一刀叶2在安装轴1上即可如图11和图12中的第一刀叶2a、2b所示，顺时针向下倾斜0°至45°设置，优选为顺时针向下倾斜10°至20°设置，也可在安装轴1上如图12中的第一刀叶2c所示，逆时针向上倾斜0°至45°设置，优选为逆时针向上倾斜10°至20°设置，该种设置使得第一刀刃22的切割面积和对物料的推送效果比较适中，因而能够在粉碎刀100正常安装到杯体内时，使得第一刀叶2能够与第二刀叶3更好地配合，以更平衡稳定地弥补因第一刀叶2的推送而形成的空隙，进而能够使物料平衡稳定地循环运动，反之若角度β太小，则第一刀叶2切割面积大，物料排出效果好，因而会导致第一刀叶2对物料的排出速度大于第二刀叶3对物料的抽取速度，从而会导致物料循环不充分，而若角度β太大，则第一刀叶2切割面积小，物料的排出速度慢，从而也会导致第一刀叶2对物料的排出速度小于第二刀叶3对物料的抽取速度，因而也不能实现物料的平衡，而将夹角β设置在大于等于负45°小于等于正45°的范围内即能够实现物料的排出与抽取的平衡，进而能够使物料平衡稳定地循环运动，以确保物料的粉碎效率和粉碎效果。此外，负45°≤β≤正45°使得β具有较宽的取值范围，从而可将 第一刀叶2的数量设置成两个或两个以上，并将两个或两个以上第一刀叶2以不同角度和/或不同高度地安装在安装轴1上，以便能够实现两个或两个以上第一刀叶2的梯级安装，进而能够利用两个或两个以上第一刀叶2实现对物料的梯级粉碎及梯级推送，因而即能够确保物料的粉碎效率和粉碎效果。
在上述实施例中，优选地，如图5至图12所示，第一刀叶2的数量为六个，第二刀叶3的数量为两个时，六个第一刀叶2中的四个第一刀叶2，即对称设置的两个第一刀叶2a和对称设置的两个第一刀叶2b安装在安装轴1的同一横截面上，同一横截面为第一横截面，第一横截面上的四个第一刀叶2两两关于安装轴1的轴线对称，即两个第一刀叶2a对称，两个第一刀叶2b对称，如图12所示，第一横截面上的四个第一刀叶2中的两个第一刀叶2a与安装轴1的横截面之间的夹角β1在大于等于负45°小于等于0°的范围内，第一横截面上的四个第一刀叶2中的另外两个第一刀叶2b与安装轴1的横截面之间的夹角β2在大于等于负20°小于等于正20°的范围内；如图12所示，六个第一刀叶2中的另外两个第一刀叶2c和两个第二刀叶3位于安装轴1的另一同一横截面上，另一同一横截面为第二横截面，其中，如图12所示，第一横截面位于第二横截面靠近连接端的一侧，第二横截面上的两个第一刀叶2c关于安装轴1的轴线对称设置，第二横截面上的两个第二刀叶3关于安装轴1的轴线对称设置，第二横截面上的两个第二刀叶3与安装轴1的横截面之间的夹角α在大于等于正45°小于等于正70°的范围内，第二横截面上的另外两个第一刀叶2c与安装轴1的横截面之间的夹角β3在大于等于0°小于等于正45°的范围内。
在该实施例中，四个第一刀叶2安装在安装轴1的同一横截面，即第一横截面上，另外两个第一刀叶2和两个第二刀叶3安装在安装轴1的另一同一横截面，即第二横截面上，使得六个第一刀叶2和两个第二刀叶3形成的八叶刀能够分成上下两层，进而能够对物料进行分层粉碎及分层推送，而第二横截面上的两个第一刀叶2与安装轴1优选呈0°-正45°的夹角，进一步优选呈正10°-正20°的夹角，而第一横截面上的四个第一刀叶2中的两个第一刀叶2与安装轴1优选呈负45°-0°的夹角，进一步优 选呈负20°-负10°的夹角，而另外两个第一刀叶2与安装轴1优选呈负20°-正20°的夹角，进一步优选呈负10°-正10°的夹角，使得六个第一刀叶2能够上下分成三层，因而能够对物料分三层进行粉碎及推动，而将六个第一刀叶2安装在上述范围内，并将第二横截面上的两个第二刀叶3与安装轴1的横截麦面优选呈正45°-正70°的夹角，进一步优选呈正50°-正60°的夹角，使得第一刀叶2对物料的切割面积和对物料的推送效果比较适中及使得第二刀叶3对物料的切割面积和对物料的抽取效果比较适中，因而便能够使第一刀叶2与第二刀叶3更好地配合，以实现物料的排出与抽取的平衡，进而能够使物料平衡稳定地循环运动，以确保物料的粉碎效率和粉碎效果。
在上述实施例中，优选地，如图1至图10所示，粉碎刀100还包括：泄压孔6，设置在第一刀叶2上和/或第二刀叶3上。
在该实施例中，通过设置泄压孔6能够在第一刀叶2和/或第二刀叶3推送物料时为第一刀叶2和/或第二刀叶3泄压，以防止第一刀叶2和/或第二刀叶3因压力过大而折断，具体地，比如，在第一刀叶2将物料推送至杯体底部时，若杯体底部的物料聚集的过多，则物料对第一刀叶2的阻力较大，而通过设置泄压孔6可利用物料与第一刀叶2之间的挤压，以使物料能够从泄压孔6内排出，从而对第一刀叶2起到泄压的作用，进而即可使第一刀叶2经久耐用而不易折断，因而即可延长产品的使用寿命，同理，在第二刀叶3抽取物料时，若抽取的物料过多，则物料对第二刀叶3的阻力较大，而通过设置泄压孔6可利用物料与第二刀叶3之间的挤压，以使物料能够从泄压孔6内排出，从而对第二刀叶3起到泄压的作用，进而即可使第二刀叶3经久耐用而不易折断，因而也可延长产品的使用寿命。当然，我们也可只在第一刀叶2上设置泄压孔6，而不在第二刀叶3上设置泄压孔6。
在上述实施例中，优选地，如图1至图12所示，泄压孔6的数量为一个或一个以上。
在该实施例中，泄压孔6的数量为一个或多个，具体地，可在第一刀叶2和第二刀叶3上均设置泄压孔6，从而能够同时利用多个泄压孔6进 行泄压，以提高粉碎刀的强度，进而即可防止粉碎刀破碎。
在上述实施例中，优选地，如图1至图10所示，至少一个第一刀叶2上均设置有泄压孔6，且如图1至图6所示，至少一个第一刀叶2上设置的泄压孔6的形状大小一致。
在该实施例中，可将第一刀叶2上均设置上泄压孔6，从而能够对所有的第一刀叶2进行泄压，以大幅度提高粉碎刀100的整体抗压能力，而一个或两个或两个以上第一刀叶2上的泄压孔6的形状大小一致使得每个第一刀叶2的泄压能力一样，进而能够使每个第一刀叶2对物料的推送效果一致，进而即可使杯体的内的物料平稳地运动，以防止物料波动。当然，也可只在部分第一刀叶2上设置泄压孔6，而在其余部分的第一刀叶2上不设置泄压孔6。
在上述实施例中，优选地，如图7至图10所示，泄压孔6包括圆形孔、腰形孔、方形孔锥形孔中的一个或多个。
在该实施例中，泄压孔6的形状和大小可以任意设置，具体地，泄压孔6可为圆形孔、腰形孔、方形孔锥形孔中的一个或多个，因为，这些孔都是比较常见的孔，因而易于加工。
其中，进一步优选地，如图1至图8所示，泄压孔6为沿着第一刀叶2或第二刀叶3方向延伸的细长孔，因为第一刀叶2和第二刀叶3一般因为细长形结构，因而通过将泄压孔6设置成细长孔能够使第一刀叶2和第二刀叶3的结构与泄压孔6的形状相适配。
本发明第二方面的实施例提供了一种粉碎刀100，用于食物处理机200，粉碎刀100包括：安装轴1，安装轴1包括安装端和连接端；两个或两个以上刀叶，刀叶安装在安装轴1上，刀叶上设置有刀刃；其中，两个或两个以上刀叶与安装轴1形成的两个或两个以上的夹角中至少有两个夹角的角度不相等；刀叶的厚度为H，厚度H的值为：1mm≤H≤5mm。
根据本发明的实施例提供的粉碎刀100，安装在搅拌器等食物处理机的杯体内，用于对杯体内的水和食材等物料进行粉碎及推送，具体地，粉碎刀100包括安装轴1和安装在安装轴1上的刀叶，其中，刀叶用于对杯体内的物料进行推送及粉碎切割，而安装轴1的连接端用于与驱动装置， 比如电机驱动连接，以在驱动装置，比如电机的作用下驱动刀叶转动，以对物料进行粉碎及推送，当然，安装轴1也可以直接是电机的电机轴。而两个或两个以上刀叶与安装轴1形成的两个或两个以上的夹角中至少有两个夹角的角度不相等，即是说两个或两个以上刀叶能够以一定角度安装在安装轴1上，且至少有两个刀叶能够与安装轴1形成不同的夹角，这样在工作状态时，就可以使得至少两个刀叶在安装轴的轴向上形成至少两个切割面，即至少两个切割面或其延长面之间形成夹角，至少两个切割面或其延长面之间形成的夹角的角度值为大于0°小于90°，该种设置即能够使粉碎刀100的多个刀叶之间在工作状态时形成至少两个不重叠的切割层，从而杯体内的物料被多层切割粉碎，进而能够将物料切割粉碎的更加彻底，以使物料切割粉碎的效果更好、效率更高，因而便能够提供产品的整体品质。而将刀叶的厚度H设置在大于等于1mm小于等于5mm的范围内即能够确保刀叶的强度，又能够防止刀叶的厚度过厚。
其中，优选地，刀刃与刀叶为一体式结构，而刀刃与刀叶为一体式结构能够提高刀刃与刀叶的连接强度，进而能够提高刀叶的抗挤压强度，以使产品经久耐用。
其中，优选地，两个或两个以上刀叶倾斜安装在安装轴1上，该种设置能够增大刀叶作用在物料上的面积，进而能够增大刀叶对物料的粉碎切割力，以便能够快速地将物料切割粉碎。
在上述实施例中，优选地，刀叶包括：至少一个第一刀叶2，第一刀叶2安装在安装轴1上，第一刀叶2上设置有第一刀刃22，第一刀刃22设置在第一刀叶2远离安装端的一面上；至少一个第二刀叶3，第二刀叶3安装在安装轴1上，第二刀叶3上设置有第二刀刃32，第二刀刃32设置在第二刀叶3靠近安装端的一面上；其中，第一刀叶2倾斜安装在安装轴1上和/或第二刀叶3倾斜安装在安装轴1上；至少一个第一刀叶2与安装轴1形成的至少一个夹角和至少一个第二刀叶3与安装轴1形成的至少一个夹角中至少有两个夹角的角度不相等。
在该实施例中，刀叶包括第一刀叶2和第二刀叶3，具体地，第一刀叶2和第二刀叶3安装在安装轴1的安装端上，安装轴1的连接端用于与 驱动装置，比如电机驱动连接，以在驱动装置，比如电机的作用下驱动第一刀叶2和第二刀叶3转动，以对物料进行粉碎及推送，当然，安装轴1也可以直接是电机的电机轴，而两个或两个以上第一刀叶2上的第一刀刃22设置在第一刀叶2远离安装端的一面上，即靠近连接端的一面上，也即第一刀刃22设置在第一刀叶2的下端面上，也即第一刀刃22的开口朝下，因此第一刀叶2在安装轴1的作用下旋转时，便能够边粉碎物料，边将物料向杯体底部及杯体的外侧推送，从而能够使物料从上至下循环运动，而当被推送到的杯体底部的物料越积越多时，先被推送至杯体底部的物料在后被推送至杯体底部的物料的挤压下，便能够顺着杯体的侧壁向上运动，以实现物料从下至上的循环运动，而在物料从下至上运动到杯体的上部时，物料便能够在重力的作用下掉落下来，而后再被第一刀刃22粉碎及向下向外推送，至此即可实现物料的一个完整循环，该种循环方式由于物料在第一刀刃22的作用下由上至下及由下至下循环运动时，第一刀刃22向下推送物料的速度，即物料向下推送速度要快于物料从杯体上部掉落下来的速度，即物料的回流速度，从而会导致杯体中部形成空隙进而形成负压，因此当杯体上部的物料再次回流而补充到该空隙时就会导致物料的波动，进而导致物料的循环翻滚运动不合理，进而使得物料不能够按规定的循环路线和理想的粉碎方位进行运动，而第二刀刃32设置在第二刀叶3靠近安装端的一面上，即第二刀刃32设置在第二刀叶3的上端面上，也即第二刀刃32的开口朝上，因此，第二刀叶3在安装轴1的作用下旋转时，便能够边粉碎物料，边将杯体中上部的周边的物料聚集抽取到杯体中上部的中间，然后随着从杯体上部掉落下来的物料一起被第一刀刃22粉碎及向下向外推送，从而通过设置第二刀刃32，第二刀刃32便能够将杯体中上部的周边的物料聚集抽取到杯体中上部的中间，以填补到物料循环过程中形成的空隙内，从而即可消除物料循环过程中形成的缝隙和负压，进而当杯体上部的物料再次回流时，便能够非常平稳地与第二刀刃32抽取的物料混合，进而被第一刀刃22粉碎并向下推送，因而即可避免物料的波动，以使物料能够按规定的循环路线和理想的粉碎方位进行循环运动，进而一方面便能够对物料进行有效粉碎，以确保物料的加工效率和加工效果，另一方面可 减小因物料波动而对安装轴1的冲击，进而使得安装轴1能够更为平稳地转动，进而即可减小搅拌器的波动，以使搅拌器平稳地转动，而搅拌器平稳地转动会降低搅拌器的噪音和摩擦生热，进而能够降低搅拌器的温升等。同时，该种设置由于物料循环时没有形成空隙，因而第一刀叶2的第一刀刃22能够始终作用在物料上，从而便能够提高粉碎刀100对物料的粉碎效率，确保粉碎刀100对物料的粉碎效果，而通过第二刀叶3的第二刀刃32的粉碎作用，能够进一步提高粉碎刀100对物料的粉碎效率，进而能够进一步确保粉碎刀100对物料的粉碎效果。而至少一个第一刀叶2与安装轴1形成的至少一个夹角和至少一个第二刀叶3与安装轴1形成的至少一个夹角中至少有两个夹角的角度不相等，即在第一刀叶2和第二刀叶3均只有一个时，第一刀叶2和第二刀叶3与安装轴1之间的夹角的角度不同，从而使得第一刀叶2和第二刀叶3能够分两层设置，而在第一刀叶2和/或第二刀叶3为两个或两个以上时，即可是两个或两个以上第一刀叶2中的至少两个与安装轴1形成至少两个不同角度的夹角，也可是两个或两个以上第二刀叶3中的至少两个与安装轴1形成至少两个不同角度的夹角，还可是一个或多个第一刀叶2和一个或多个第二刀叶3与安装轴1形成至少两个不同角度的夹角，也就是说，即可以是至少一个刀叶与至少一个第二刀叶3分层设置，也可以是多个第一刀叶2之间分层设置，还可以是多个第二刀叶3之间分层设置，该种设置即能够使粉碎刀100的多个刀叶之间形成至少两个分割层，从而能够对物料进行分层粉碎，进而能够对物料切割粉碎的更加彻底，以使物料切割粉碎的效果更好、效率更高。
其中，优选地，如图1至图12所示，第一刀叶2和第二刀叶3中至少有一个倾斜设置，即要么第一刀叶2倾斜设置，要么第二刀叶3倾斜设置，要么第一刀叶2和第二刀叶3同时倾斜设置，同时，优选地，第一刀叶2位于第二刀叶3远离安装端的一方，该种设置能够使第一刀叶2和第二刀叶3形成高度差，因而能够更好地利用位于下方的第一刀叶2来将物料向下推送，及更好地利用位于上方的第二刀叶3来将物料补充到第一刀叶2形成的空隙内。
在上述实施例中，优选地，如图1至图12所示，第一刀刃22与第一 刀叶2和/或第二刀刃32与第二刀叶3为一体式结构。
在该实施例中，第一刀刃22与第一刀叶2和/或第二刀刃32与第二刀叶3为一体式结构能够提高第一刀刃22与第一刀叶2和/或第二刀刃32与第二刀叶3的连接强度，进而能够提高第一刀叶2和第二刀叶3的抗挤压强度，以使产品经久耐用。
其中，优选地，第一刀叶2和第二刀叶3的厚度为H，厚度H的值为：1mm≤H≤5mm。通过将第一刀叶2和第二刀叶3的厚度H设置在大于等于1mm小于等于5mm的范围内即能够确保第一刀叶2和第二刀叶3的强度，又能够防止第一刀叶2和第二刀叶3的厚度过厚。
在上述实施例中，优选地，如图1至图12所示，第一刀刃22设置在第一刀叶2的一侧上，第二刀刃32设置在第二刀叶3的一侧上。
在该实施例中，可只在第一刀叶2和第二刀叶3的单侧上设置刀刃，因为，搅拌器在搅拌食物时都是沿同一方向搅拌粉碎食物，因此，在第一刀叶2和第二刀叶3的单侧上设置刀刃即可满足产品的要求，而只在第一刀叶2和第二刀叶3的单侧上设置刀刃能够简化第一刀叶2和第二刀叶3的结构，因而能够简化加工工序，降低加工成本。
在另一实施例中，优选地，至少一个第一刀叶2的两侧上均设置有第一刀刃22，和/或至少一个第二刀叶3的两侧上均设置有第二刀刃32。
在该实施例中，通过在第一刀叶2的两侧设置第一刀刃22，使得第一刀叶2的两侧均能够用于物料粉碎，因而第一刀叶2无论是顺时针旋转还是逆时针旋转均能够对物料进行粉碎，进而能够实现第一刀叶2的双面粉碎。同理，通过在第二刀叶3的两侧均设置第二刀刃32，使得第二刀叶3的两侧均能够用于物料粉碎，因而第二刀叶3无论是顺时针旋转还是逆时针旋转均能够对物料进行粉碎，进而能够实现第二刀叶3的双面粉碎。
其中，优选地，如图1至图10所示，至少一个第二刀叶3中至少有一个第二刀叶3位于一第一刀叶2靠近安装端的一方，即至少有一个第二刀叶3位于一第一刀叶2的上方，以使第一刀叶2和第二刀叶3能够形成两层或两层以上设置，以便能够对食材进行分层切割，进而便能够提高粉碎刀对食材的粉碎效率和粉碎效果。
其中，优选地，如图1至图10所示，至少一个第二刀叶3中至少有一个第二刀叶3位于一第一刀叶2靠近安装端的一方，即至少有一个第二刀叶3位于一第一刀叶2的上方，以使第一刀叶2和第二刀叶3能够形成两层或两层以上设置，以便能够对物料进行分层切割，进而便能够提高粉碎刀对物料的粉碎效率和粉碎效果。
在上述实施例中，优选地，第二刀叶3的一端安装在安装轴1上，第二刀叶3的另一端向安装端的端部方向倾斜延伸；第一刀叶2的一端安装在安装轴1上，第一刀叶2的另一端向连接端的端部方向倾斜延伸或第一刀叶2的另一端向安装端的端部方向倾斜延伸或第一刀叶2垂直安装在安装轴1上。
在该实施例中，第二刀叶3的一端安装在安装轴1上，第二刀叶3的另一端向安装端的端部方向倾斜延伸，即第二刀叶3倾斜向上设置，该种设置由于第二刀叶3倾斜向上设置，因此，便能够更高效地将杯体内中上部的物料聚集抽取到第一刀叶2形成的空隙内，以使物料流动的更加平稳。而在第二刀叶3倾斜向上设置时，第一刀叶2即可倾斜向下设置，也可倾斜向上设置，也可垂直于安装轴1设置，但优选地，可将第一刀叶2倾斜向下设置或倾斜向上设置，而通过将第一刀叶2倾斜设置，即非水平设置，使得第一刀叶2能够更好地与物料接触，因而能够提高第一刀叶2对物料的粉碎及向下向外的推送效果，进而即可提高产品的粉碎效率，确保产品的粉碎效果。其中，具体地，在两个或两个以上第一刀叶2呈双层设置时，可将上层的第一刀叶2倾斜向上设置，而将下层的第一刀叶2倾斜向下设置，以便能够使产品的结构分布的更加合理紧凑。
在上述实施例中，优选地，如图1至图12所示，第一刀叶2的数量为偶数个，第二刀叶3的数量为偶数个。
在该实施例中，第一刀叶2和第二刀叶3的数量为偶数个，能够使两两第一刀叶2和两两第二刀叶3呈对称设置，进而能够使第一刀叶2和第二刀叶3受到的物料的阻力一致，因而能够使第一刀叶2和第二刀叶3的受力更加均衡，以防止出现受力薄弱部，进而即能够相对提高第一刀叶2和第二刀叶3的强度，同时，该种设置能够依次形成四叶刀或八叶刀或十 二叶刀等多种规格，进而能够提高粉碎刀100的规格。此外中心对称地结构更易加工，因而能够降低产品的加工难度，提高产品的加工效率，降低产品的加工成本。
当然，第一刀叶2的数量和第二刀叶3的数量也可为奇数个，从而可对应形成三叶刀、五叶刀、七叶刀等多种规格。
在上述实施例中，优选地，如图1和图2所示，第一刀叶2的数量为两个或如图3和图4所示，第一刀叶2的数量为四个，或如图5至图10所示，第一刀叶2的数量为六个；和/或如图1至图10所示，第二刀叶3的数量为两个，当然第二刀叶3的数量也可为四个。
在该实施例中，如图1和图2所示，第一刀叶2的数量和第二刀叶3的数量均为两个时能够形成四叶刀，如图3和图4所示，第二刀叶3的数量为两个，而第一刀叶2的数量为四个，或第二刀叶3的数量为四个，而第一刀叶2的数量为两个时能够形成六叶刀，而第二刀叶3的数量和第一刀叶2的数量均为四个时能够形成八叶刀，而如图5至图10所示，第二刀叶3的数量为两个，第一刀叶2的数量为六个时也能够形成八叶刀，此时，优选地，可如图5至图10所示，将四个第一刀叶2设置在安装轴1的同一横截面上，而将两个第一刀叶2和两个第二刀叶3相互交替地设置在四个第一刀叶2的上面，并位于安装轴1的另一横截面上，而该些规格的粉碎刀100均能够使物料平稳地循环运动，且该些规格的粉碎刀100即能够对物料进行充分粉碎，又能够使得产品的结构较为简单，因而能够在确保粉碎效果的同时，简化产品的结构，降低产品的成本。
在上述实施例中，优选地，如图11和图12所示，第一刀叶的数量为六个，第二刀叶的数量为两个；六个第一刀叶2中的四个第一刀叶2，即对称设置的两个第一刀叶2a和对称设置的两个第一刀叶2b安装在安装轴1的同一横截面上，同一横截面为第一横截面；六个第一刀叶2中的另外两个第一刀叶2c和两个第二刀叶3位于安装轴1的另一同一横截面上，另一同一横截面为第二横截面，其中，第一横截面位于第二横截面靠近连接端的一侧。
在该实施例中，四个第一刀叶2安装在安装轴1的同一横截面，即第 一横截面上，另外两个第一刀叶2和两个第二刀叶3安装在安装轴1的另一同一横截面，即第二横截面上，使得六个第一刀叶2和两个第二刀叶3形成的八叶刀能够分成上下两层，进而能够对物料进行分层粉碎及分层推送。
在上述实施例中，优选地，如图1至图12所示，第一横截面上的四个第一刀叶2相互对称，具体地，即可呈中心对称，也可呈轴对称，即两个第一刀叶2a对称，两个第一刀叶2b对称，第二横截面上的两个第一刀叶2c相互对称，具体地，即可呈中心对称，也可呈轴对称，第二横截面上的两个第二刀叶3相互对称，具体地，即可呈中心对称，也可呈轴对称。
在该实施例中，两两第一刀叶2和两两第二刀叶3呈对称设置，具体地，即可呈中心对称，也可呈轴对称设置，进而能够使第一刀叶2和第二刀叶3受到的物料的阻力一致，因而能够使第一刀叶2和第二刀叶3的受力更加均衡，以防止出现受力薄弱部，进而即能够相对提高第一刀叶2和第二刀叶3的强度，同时，通过将六个第一刀叶2和两个第二刀叶3两两对称设置，能够使粉碎刀100整体呈对称结构，因而一方面能够提高产品的对称美，另一方面还能够使产品的重心居中，因而可提高产品的稳定性，进而可降低产品的波动和噪音。
在上述实施例中，优选地，如图12所示，第一横截面上的四个第一刀叶2中的两个第一刀叶2a与安装轴1的横截面之间的夹角β1在大于等于负45°小于等于0°的范围内，如图11所示，第一横截面上的四个第一刀叶2中的另外两个第一刀叶2b与安装轴1的横截面之间的夹角β2在大于等于负20°小于等于正20°的范围内；如图11所示，第二横截面上的两个第二刀叶3与安装轴1的横截面之间的夹角α在大于等于正45°小于等于正70°的范围内，如图12所示，第二横截面上的另外两个第一刀叶2c与安装轴1的横截面之间的夹角β3在大于等于0°小于等于正45°的范围内。
在该实施例中，第一刀叶2在安装轴1上即可如图11和图12中的第一刀叶2a、2b所示，顺时针向下倾斜0°至45°设置，优选为顺时针向下倾斜10°至20°设置，也可在安装轴1上如图12中的第一刀叶2c所示， 逆时针向上倾斜0°至45°设置，优选为逆时针向上倾斜10°至20°设置，该种设置使得第一刀刃22的切割面积和对物料的推送效果比较适中，因而能够在粉碎刀100正常安装到杯体内时，使得第一刀叶2能够与第二刀叶3更好地配合，以更平衡稳定地弥补因第一刀叶2的推送而形成的空隙，进而能够使物料平衡稳定地循环运动，反之若角度β太小，则第一刀叶2切割面积大，物料排出效果好，因而会导致第一刀叶2对物料的排出速度大于第二刀叶3对物料的抽取速度，从而会导致物料循环不充分，而若角度β太大，则第一刀叶2切割面积小，物料的排出速度慢，从而也会导致第一刀叶2对物料的排出速度小于第二刀叶3对物料的抽取速度，因而也不能实现物料的平衡，而将夹角β设置在大于等于负45°小于等于正45°的范围内即能够实现物料的排出与抽取的平衡，进而能够使物料平衡稳定地循环运动，以确保物料的粉碎效率和粉碎效果。同时，该种设置将多个第一刀叶2以不同角度和/或不同高度地安装在安装轴1上，能够实现多个第一刀叶2的梯级安装，进而能够利用多个第一刀叶2实现对物料的梯级粉碎及机梯级推送，因而即能够确保物料的粉碎效率和粉碎效果。而第二刀叶3与安装轴1的横截面即水平面之间的夹角α优选在大于等正45°小于等于正70°的范围内，即第二刀叶3优选在安装轴1上逆时针向上倾斜45°至70°设置，该种设置使得第二刀刃32的切割面积和对物料的抽取效果比较适中，因而能够在粉碎刀100正常安装到杯体内时，使得第二刀叶3能够与第一刀叶2更好地配合，以更平衡稳定地弥补因第一刀刃22的推送而形成的空隙，进而能够使物料平衡稳定地循环运动，具体地，若角度α太小，则第二刀叶3切割面积大，抽水效果好，因而会导致第二刀叶3对物料的抽取速度大于第一刀叶2对物料的排出速度，从而会导致物料循环不充分，而若角度α太大，则第二刀叶3切割面积小，抽水效果差，也会导致第二刀叶3对物料的抽取速度小于第一刀叶2对物料的排出速度，因而也不能实现物料的平衡，而将夹角α设置在大于等正45°小于等于正70°的范围内，使得第二刀叶3对物料的抽取比较适中，因而即能够与第一刀叶2更好地配合，以实现物料的排出与抽取的平衡，进而能够使物料平衡稳定地循环运动，以确保物料的粉碎效率和粉碎效果。
其中，在本说明书中，逆时针旋转的角度为正，顺时针旋转的角度为负。
其中，优选地，正50°≤α≤正60°，该种设置能够更好地实现物料的排出与抽取的平衡，进而能够更好地使物料平衡稳定地循环运动，以更好地确保物料的粉碎效率和粉碎效果。
在上述实施例中，优选地，两个第二刀叶3的总长度之和与六个第一刀叶2的总长度之和的比值为A，其中，0.05≤A≤0.8或0.1≤A≤0.4。
在该实施例中，两个第二刀叶3的总长度之和与六个第一刀叶2的总长度之和的比值A，即所有第二刀叶3的长度之和与所有第一刀叶2的长度之和的比值A不宜过大也不宜过小，具体地，若A值过小，则第二刀叶3的对物料的抽取聚集效率低，从而导致第二刀叶3无法填补第一刀叶2形成的空隙，从而会导致物料的循环的效率低，因而会造成物料的粉碎效果差，但若A值过大，则第二刀叶3的对物料的抽取聚集效率偏高，从而导致第一刀叶2无法及时将中部的物料排出至杯体的底部，进而会造成物料推挤，因而也会导致物料的循环的效率低，从而会造成物料的粉碎效果差，而通过将比值A设置在大于等于0.05小于等于0.8的范围内，即能够确保杯体内物料的循环平衡稳定，又能够提高粉碎效果和粉碎效率，进而会提高产品的整体品质。
其中，优选地，0.1≤A≤0.4，即比值A的值优选设置在大于等于0.1小于等于0.4的范围内，该种设置，能够使物料的循环达到最佳的平衡状态，因而能够进一步提高粉碎效果和粉碎效率，以进一步提高产品的整体品质。
在上述实施例中，优选地，如图1至图10所示，粉碎刀100还包括：第一刀根部4，第一刀根部4套设安装在安装轴1上；第二刀根部5，第二刀根部5套设安装在安装轴1上，并位于第一刀根部4靠近安装端的一方；其中，至少一个第一刀叶2设置在第一刀根部4上或至少一个第一刀叶2设置在第一刀根部4和第二刀根部5上；至少一个第二刀叶3设置在第二刀根部5上。
在该实施例中，可在安装轴1上设置两个刀根部，即第一刀根部4和 第二刀根部5，从而能够将至少一个第一刀叶2和至少一个第二刀叶3安装在第一刀根部4或第二刀根部5上，以使粉碎刀100形成双层结构，其中，具体地，在第一刀叶2的数量和第二刀叶3的数量相等时，可将所有的第一刀叶2全部安装在下层，即第一刀根部4上，同时将所有的第二刀叶3全部安装在上层，即第二刀根部5上，而在第一刀叶2的数量比第二刀叶3的数量多时，可将大部分第一刀叶2安装在下层，即第一刀根部4上，而将剩下的第一刀叶2与所有的第二刀叶3交替对称地安装在上层，即第二刀根部5上，此时，优选地，将第二刀根部5上的第一刀叶2倾斜向上设置，以使其倾斜方向能够与第二刀叶3的倾斜方向一致，从而即可确保产品的美观性和对称性。
此外，还可设置第三刀根部或第四刀根部等，以便能够将两个或两个以上第一刀叶2安装成多层，或者将两个或两个以上第二刀叶3安装成多层，以便能够将产品设计成三层刀叶、四层刀叶或更多层刀叶的结构。
在上述实施例中，优选地，如图1至图10所示，至少一个第一刀叶2均设置在第一刀根部4上时，第一刀根部4与第一刀叶2为一体式结构，在第二刀根部5上也设置有第一刀叶2时，第二刀根部5与第一刀叶2为一体式结构；和/或第二刀根部5与至少一个第二刀叶3为一体式结构。
在该实施例中，可优选将第一刀叶2和第二刀叶3与对应的刀根部，即第一刀根部4和第二刀根部5设置为一体式结构，因为，一体式结构的力学性能好，因而能够确保刀根部和刀叶之间的连接强度，其中，优选地，可将刀叶和刀根部一体制成，批量生产，以提高产品的加工效率，降低产品的加工成本。具体地，可利用同一金属板折弯出第一刀叶2、第二刀叶3和对应的刀根部，以方便、快速且低成本地实现第二刀和第一刀叶2的加工。
在上述实施例中，优选地，第一刀根部4与第二刀根部5为一体式结构。
在该实施例中，可优选将第一刀根部4与第二刀根部5设置为一体式结构，因为，一体式结构的力学性能好，因而能够确保第一刀根部4与第二刀根部5之间的连接强度，其中，优选地，可将第一刀根部4与第二刀 根部5一体制成，批量生产，以提高产品的加工效率，降低产品的加工成本。
当然，在另一实施例中，第一刀根部4与第二刀根部5也可为分体式结构，此时，便于将第一刀根部4和第二刀根部5与对应的刀叶一体制成、批量生产。
在上述实施例中，优选地，如图1至图10所示，第一刀根部4上设置有第一通孔42，第二刀根部5上设置有第二通孔52，第一刀根部4通过第一通孔42套设安装在安装轴1上，第二刀根部5通过第二通孔52套设安装在安装轴1上。
在该实施例中，可在第一刀根部4上设置第一通孔42，而在第二刀根部5上设置第二通孔52，从而可将安装轴1的安装端依次穿过第一通孔42和第二通孔52，以实现第一刀叶2和第二刀叶3的精确安装。
在上述实施例中，优选地，安装轴1的安装端上设置有环形安装槽12，第一刀根部4通过第一通孔42与环形安装槽12的配合套设安装在安装轴1上，第二刀根部5通过第二通孔52与环形安装槽12的配合套设安装在安装轴1上；其中，安装端的端部上设置有压边，压边压合在第二刀根部5上。
在该实施例中，通过设置环形安装槽12能够利用环形安装槽12来对第一刀根部4和第二刀根部5进行定位安装，具体地，可将安装轴1的安装端依次穿过第一通孔42和第二通孔52，然后将第一刀根部4和第二刀根部5卡在环形安装槽12内，以利用环形安装槽12实现对第一刀根部4和第二刀根部5的卡扣安装。同时，在第一刀根部4和第二刀根部5套设安装在安装轴1上的环形安装槽12上后，可将安装轴1伸出第二刀根部5的部分压平后压合在第二刀根部5上，以便能够简单快速地实现第二刀根部5和第一刀跟与安装轴1之简的固定及安装。
当然，在另一实施例中，也可利用安装轴1和第一通孔42和第二通孔52的过盈配合实现第一刀根部4和第二刀根部5与安装轴1之间的安装。
在上述实施例中，优选地，如图1、图3和图5所示，第一刀根部4贴合在第二刀根部5上。
在该实施例中，第一刀根部4贴合在第二刀根部5上，因此能够使第一刀叶2和第二刀叶3形成一个整体而进行同步旋转，因而能够使第一刀叶2和第二刀叶3对物料进行同步粉碎，进而能够使第一刀叶2和第二刀叶3更好地同步配合，以提高对物料的粉碎效率，同时，第一刀根部4贴合在第二刀根部5上还能够使得第一刀根部4和第二刀根部5相互支撑，进而能够提高第一刀根部4和第二刀根部5的强度，此外，该种设置还能够使粉碎刀100的结构更为紧凑合理，因而能够减小产品的整体体积。还有该种设置能够防止第一刀根部4和第二刀根部5之间形成狭窄缝隙，进而更利于用户对粉碎刀100进行清洗。
在上述实施例中，优选地，如图2、图4和图12所示，第一刀根部4和第二刀根部5的形状大小一致。
在该实施例中，第一刀根部4和第二刀根部5的形状大小一致，一方面能够使第一刀叶2和第二刀叶3的强度一致，另一方面能够提高减少零部件的类型，以利于产品的标准化。当然，在另一实施例中，第一刀根部4和第二刀根部5的形状大小也可不一致。
在上述实施例中，优选地，如图2、图4和图12所示，第一刀根部4和/或第二刀根部5为方形，当然，第一刀根部4也可为圆形，三角形，椭圆形或五边形，具体地，第一刀根部4和/或第二刀根部5的形状可根据第一刀叶2和第二刀叶3的数量变化而变化。
在该实施例中，第一刀根部4和/或第二刀根部5优选为方形，因为方形相比于圆形、椭圆形而言更易加工，因而能够降低产品的加工成本，提高产品的加工效率。具体地比如，该种结构使得第一刀叶2和第二刀叶3能够通过金属板快速简单地折弯形成，而圆形则无法通过金属板直接折弯形成。当然，也可为圆形，三角形，椭圆形，五边形或者任意其它形状。
在上述实施例中，优选地，如图1至图12所示，第一刀根部4与安装轴1相互垂直安装，第二刀根部5与安装轴1相互垂直安装。
在该实施例中，第一刀根部4与安装轴1相互垂直安装，第二刀根部5与安装轴1相互垂直安装能够使第一刀根部4和第二刀根部5之间安装的更加牢靠，因而能够使第一刀叶2和第二刀叶3在粉碎物料时不会与安 装轴1脱落，从而即可防止第一刀叶2和第二刀叶3脱落伤人，进而即可确保用户的使用安全。具体地，可将第二刀叶3与第二刀根部5之间呈一角度设置，以确保第二刀根部5与安装轴1相互垂直安装时，刀叶能够向上倾斜设置，同时，可使第一刀叶与第一刀根部4之间呈一角度设置，以确保第一刀根部4与安装轴1相互垂直安装时，第一刀叶2能够向下倾斜设置。
在上述实施例中，优选地，如图1至图12所示，安装轴1为圆形轴。
在该实施例中，安装轴1优选为圆形轴，因为圆形轴更易与电机等配合，从而能够更利于对安装轴1进行驱动。
在上述实施例中，优选地，第一刀叶2和/或第二刀叶3由金属材料制成，因为，金属材料的强度高，耐磨性好，因而能够更好地粉碎物料。当然，第二刀叶3和/或第一刀叶2也可为其它硬度比较高的材料制成。
在上述实施例中，优选地，如图1、图3和图5所示，第一刀叶2远离安装轴1的一端上设置有压板24。
在该实施例中，通过在第一刀叶2远离安装轴1的一端(即第一刀叶2的尾部)上设置压板24，从而能够通过压板24来向将物料推送至杯体底部，而压板24的设置能够增大第一刀叶2与物料的接触面积，因而能够增大第一刀叶2对物料的推力，进而能够加快物料的循环速度，因而能够提高产品的粉碎效率。
在上述实施例中，优选地，如图12所示，压板24与第一刀叶2之间的角度为γ，其中，夹角γ的值为：90°<γ≤180°，或夹角γ的值为：135°≤γ≤180°，或夹角γ的值为160°≤γ≤170°，其中，优选地，135°≤γ≤180°。
在该实施例中，通过将压板24与第一刀叶2之间的夹角设置在大于等于135°小于等于180°的范围内，能够确保第一刀叶2向下向外侧的压水作用，以便能够使物料的内外循环快速，顺畅，同时该种设置还能够加大第一刀叶2的切割投影面积，因而能最大限度的提高粉碎效果和粉碎效率。
其中，进一步优选地，夹角γ的值为：160°≤γ≤170°。
在上述实施例中，优选地，如图1至图10所示，粉碎刀100还包括： 泄压孔6，设置在刀叶上，具体地，比如设置在第一刀叶2上和/或第二刀叶3上。
在该实施例中，通过设置泄压孔6能够在第一刀叶2和/或第二刀叶3推送物料时为第一刀叶2和/或第二刀叶3泄压，以防止第一刀叶2和/或第二刀叶3因压力过大而折断，具体地，比如，在第一刀叶2将物料推送至杯体底部时，若杯体底部的物料聚集的过多，则物料对第一刀叶2的阻力较大，而通过设置泄压孔6可利用物料与第一刀叶2之间的挤压，以使物料能够从泄压孔6内排出，从而对第一刀叶2起到泄压的作用，进而即可使第一刀叶2经久耐用而不易折断，因而即可延长产品的使用寿命，同理，在第二刀叶3抽取物料时，若抽取的物料过多，则物料对第二刀叶3的阻力较大，而通过设置泄压孔6可利用物料与第二刀叶3之间的挤压，以使物料能够从泄压孔6内排出，从而对第二刀叶3起到泄压的作用，进而即可使第二刀叶3经久耐用而不易折断，因而也可延长产品的使用寿命。当然，我们也可只在第一刀叶2上设置泄压孔6，而不在第二刀叶3上设置泄压孔6。
在上述实施例中，优选地，如图1至图10所示，至少一个第一刀叶2上均设置有泄压孔6，且如图1至图6所示，至少一个第一刀叶2上设置的泄压孔6的形状大小一致。
在该实施例中，可将第一刀叶2上均设置上泄压孔6，从而能够对所有的第一刀叶2进行泄压，以大幅度提高粉碎刀100的整体抗压能力，而一个或两个或两个以上第一刀叶2上的泄压孔6的形状大小一致使得每个第一刀叶2的泄压能力一样，进而能够使每个第一刀叶2对物料的推送效果一致，进而即可使杯体的内的物料平稳地运动，以防止物料波动。当然，也可只在部分第一刀叶2上设置泄压孔6，而在其余部分的第一刀叶2上不设置泄压孔6。
在上述实施例中，优选地，如图7和图8所示，泄压孔6包括圆形孔、腰形孔、方形孔锥形孔中的一个或多个。
在该实施例中，泄压孔6的形状和大小可以任意设置，具体地，泄压孔6可为圆形孔、腰形孔、方形孔锥形孔中的一个或多个，因为，这些孔 都是比较常见的孔，因而易于加工。
其中，进一步优选地，如图1至图10所示，泄压孔6为沿着第一刀叶2或第二刀叶3方向延伸的细长孔，因为第一刀叶2和第二刀叶3一般因为细长形结构，因而通过将泄压孔6设置成细长孔能够使第一刀叶2和第二刀叶3的结构与泄压孔6的形状相适配。
如图13所示，本发明第三方面的实施例提供了一种食物处理机200，该食物处理机200包括：机座；杯体组件，杯体组件包括杯体和第一方面和第二方面任一项实施例提供的粉碎刀100，粉碎刀100安装在杯体内。
