请参阅图1至图3，本申请实施方式的旋转机构10用于食物处理器，旋转机构10包括第一刀轴11、第二刀轴12和齿轮传动结构13。第二刀轴12与第一刀轴11同轴设置。齿轮传动结构13包括第一中心齿轮112、第二中心齿轮122和传动轮组131。第一中心齿轮112固定在第一刀轴11。第二中心齿轮122固定在第二刀轴12。传动轮组131包括与第一中心齿轮112啮合的第一传动齿轮1311和与第二中心齿轮122啮合的第二传动齿轮1312，第一传动齿轮1311用于驱动第二传动齿轮1312转动。
本申请实施方式的旋转机构10的齿轮传动结构13的第一传动齿轮1311和第二传动齿轮1312分别和第一中心齿轮112和第二中心齿轮122啮合，通过第一传动齿轮1311和第二传动齿轮1312来驱动第一中心齿轮112和第二中心齿轮122转动，如此能够使得第一中心齿轮112和第二中心齿轮122转动更加高效，从而提升第一刀轴11和第二刀轴12的转动效率。
具体地，由于第一刀轴11与第一中心齿轮112固定，因此第一中心齿轮112随着第一刀轴11的转动而转动。由于第一中心齿轮112和第一传动齿轮1311啮合。第一中心齿轮112转动时候会带动第一传动齿轮1311转动。由于第二传动齿轮1312与第一传动齿轮1311啮合。因此在第一传动齿轮1311转动时，第二传动齿轮1312也会随着第一传动齿轮1311转动。由于第二中心齿轮122与第二传动齿轮131啮合。因此第二传动齿轮1312转动时候会带动第二中心齿轮122转动。由于第二中心齿轮122和第二刀轴12固定。因此第二中心轮转动会带动第二刀轴12转动。如此，在第一刀轴11转动时可以通过第一中心齿轮112、第一传动齿轮1311、第二传动齿轮1312、第二中心齿轮122驱动第二刀轴12转动。
在某些实施方式中，所述第一传动齿轮1311与所述第二传动齿轮1312啮合。
如此设置，第一传动齿轮1311转动能够带动第二传动齿轮1312转动，从而驱动第一中心齿轮122转动。
具体地，第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮1312的模数相同且齿数相近。
第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮1312的齿数相近指的是，第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮 1312的齿数的数量相差不超过10。
例如，第一中心齿轮112的模数m1可为1，齿数Z1可以为27、第二中心齿轮122的模数m2可为1，齿数Z2可以为27、第一传动齿轮1311的模数m3可为1，齿数Z3可以为25、第二传动齿轮1312的模数m4可为1，齿数Z4可以为25。只需要第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮1312的模数相同，齿数相近即可。
由于第一中心齿轮112与第一传动齿轮1311啮合。第一传动齿轮1311是用于驱动第二传动齿轮1312转动。第二传动齿轮1312与第二中心齿轮122啮合。当第一中心齿轮112转动时，第一传动齿轮1311也会转动，第一传动齿轮1311的转动会带动第二传动齿轮1312的转动。第二传动齿轮1312转动会带动第二中心齿轮122转动。因此在第一中心齿轮112转动时候，第二中心齿轮122也会跟着转动。当第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮1312的模数相同且齿数相近的时候，第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮1312的转动速度相近。如此能够实现齿轮的等寿命设计。不会出现第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮1312中的一个或者多个因为转动速度过快导致损坏。第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮1312的转动速度相近能够使得齿轮传动结构13的啮合频率在一个比较小的频段，有利于减小齿轮传动结构13在转动过程中产生的噪音。
本实施方式中，第一传动齿轮1311和第二传动齿轮1312部分啮合，此时，第一传动齿轮1311的高度小于第二传动齿轮1312的高度。如此可以使得第一传动齿轮1311仅仅和第一中心齿轮112啮合，第二传动齿轮1312仅仅和第二中心齿轮122啮合。不会出现由于第一传动齿轮1311与第二中心齿轮122啮合或者第二传动齿轮1312和第一中心齿轮112啮合导致齿轮传动结构13损坏的情况。
在其他实施方式中，传动轮组131还可以包括N个第三传动齿轮，N为自然数，且N≥1。N个第三传动齿轮位于第一传动齿轮1311和第二传动齿轮1312之间，且相邻两个传动轮啮合。当第三传动齿轮的数量N为奇数时，第一传动齿轮1311和第二传动齿轮1312的转动方向相同。当第三传动齿轮的数量N为偶数时，第一传动齿轮1311和第二传动齿轮1312的转动方向相反。
当第三传动齿轮的数量N为奇数时，第一传动齿轮1311和第二传动齿轮1312的转动方向相同指的是。例如，当第三传动齿轮的数量N为1时，第一传动齿轮1311和第二传动齿轮1312之间啮合有第三传动齿轮。当第一传动齿轮1311正向转动时候。由于第三传动齿轮 与第一传动齿轮1311啮合。因此第一传动齿轮1311正向转动时会带动第三传动齿轮反向转动。由于第三传动齿轮与第二传动齿轮1312啮合。因此第三传动齿轮反向转动时会带动第二传动齿轮1312正向转动。如此，使得第一传动齿轮1311和第二传动齿轮1312转动方向相同。
当第三传动齿轮的数量N为偶数时，第一传动齿轮1311和第二传动齿轮1312的转动方向相反指的是。例如，当第三传动齿轮的数量N为2时，第一传动齿轮1311和第二传动齿轮1312之间啮合两个第三传动齿轮。当第一传动齿轮1311正向转动时候。由于第一个第三传动齿轮与第一传动齿轮1311啮合。因此第一传动齿轮1311正向转动时会带动第一个第三传动齿轮反向转动。当第一个第三传动齿轮反向转动时候。由于第二个第三传动齿轮与与第一个第三传动齿轮啮合。因此第一个第三传动齿轮反向转动时候会带动第二个第三传动齿轮正向转动。当第二个第三传动齿轮正向转动时。由于第二个第三传动齿轮和第二传动齿轮1312啮合。因此第二个第三传动齿轮正向转动会带动第二传动齿轮1312反向转动。如此，使得第一传动齿轮1311和第二传动齿轮1312转动方向相反
具体地，第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮1312可以采用精钢制成。精钢具有硬度高，耐磨性好的优点。因此，采用精钢制成的第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮1312寿命更加高，摩擦力更小。降低旋转机构10噪声的同时还能提高旋转机构10的使用年限。可以理解的是，第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮1312不仅仅可以采用精钢制成，可以根据不同情况采用不同的材料制成。例如，第一中心齿轮112、第二中心齿轮122、第一传动齿轮1311和第二传动齿轮1312可以采用铸铁制成。
请参阅图4和图5，在某些实施方式中，传动轮组131的数量为多组。多组传动轮组131绕第一中心齿轮112的周向间隔分布。
传动轮组131数量多组能够提升第二中心齿轮122的转动效率，从而提升旋转机构10的转动效率，使得旋转机构10转动更加快速。
具体地，传动轮组131的组数可以为1～8。优选地，本实施方式中，传动轮组131的组数为3。
请参阅图2和图6，在某些实施方式中，第一刀轴11穿过第二刀轴12，第一刀轴11远离第一中心齿轮112的一端伸出第二刀轴12，第一刀轴11与第二刀轴12能够相对转动。
如此设置，第一刀轴11和第二刀轴12之间不会互相影响彼此的转动，如此使得旋转机构10能够实现第一刀轴11和第二刀轴12同时转动，提升旋转机构10的旋转性能。
具体地，请进一步参阅图6，第二刀轴12内形成有上下贯通容置空间123，第一刀轴11位于容置空间123内且第一刀轴11远离轮盘的一端伸出容置空间123。第二刀轴12上设有第一轴承124和第二轴承125，第一刀轴11穿过第一轴承124和第二轴承125实现第二刀轴12能够相对第一刀轴11转动。
进一步地，第一刀轴11和第二刀轴12呈圆柱形。
更进一步地，具体地，第一刀轴11和第二刀轴12可以采用精钢制成。精钢具有硬度高，表面光滑的特点。因此，采用精钢制成的第一刀轴11和第二刀轴12能够使得第一刀轴11和第二刀轴12硬度更加高，不容易损坏。可以理解的是，第一刀轴11和第二刀轴12不仅仅可以采用精钢制成。可以根据不同的需求采用不同的材料制成。例如，第一刀轴11和第二刀轴12可以铁合金制成。
请参阅图1至图3，在某些实施方式中，旋转机构10还包括壳体14，壳体14包括外壳141和底盖142。底盖142与外壳141固定连接。外壳141和底盖142共同限定出放置空间143，齿轮传动结构13收容于放置空间143内，第一刀轴11及第二刀轴12穿过外壳141并伸出至外壳141外。
壳体14的放置空间143的设置能够使得齿轮传动结构13稳定的设置于壳体14，使得结构更加紧凑，在旋转机构10转动时候不会出现由于齿轮传动结构13的移动导致旋转机构10转动效率的降低。并且壳体14的设置能够保护齿轮传动结构13，不让齿轮传动结构13暴露出来，因此齿轮传动结构13不会受到外界的干扰以致影响齿轮传动结构13的转动效率。
具体地，外壳141和底盖142可以采用精钢制成。精钢具有硬度高，表面光滑的特点。因此，采用精钢制成的外壳141和底盖142能够使得壳体14硬度更加高，不容易损坏。可以理解的是，外壳141和底盖142不仅仅可以采用精钢制成。可以根据不同的需求采用不同的材料制成。例如，外壳141和底盖142可以铁合金制成。
进一步地，外壳141和底盖142可以采用螺丝固定。可以理解的是，外壳141和底盖142不仅仅可以采用螺丝固定，可以根据不同的情况采用不同的连接方式。例如，外壳141和底盖142可以采用卡接的形式连接。在此不做限定。
固定连接指的是，使得两个元件不会发生相对转动的连接方式。例如，外壳141可以采用螺丝固定的方式与底盖142连接。
更进一步地，外壳141周围设有胶圈23，胶圈23能够能够防止水进入旋转机构10内造成旋转机构10的损坏。
请参阅图2、图4和图7，在某些实施方式中，旋转机构10还包括固定箱15，固定箱 15位于放置空间143内并且与底盖142固定连接，固定箱15内设有固定空间151，齿轮传动结构13位于固定空间151内。
固定箱15的设置能够使得齿轮传动结构13更加稳定，不会出现由于齿轮传动结构13松动降低旋转机构10的工作效率。
在某些实施方式中，固定箱15包括上板152、支撑板153和下板154，支撑板153连接上板152和下板154，支撑板153环形设于上板152和下板154的边缘，上板152、支撑板153和下板154共同限定出固定空间151，传动轮组131转动地设置在下板154。
上板152、支撑板153和下板154的设置使得固定箱15安装和拆卸都十分方便。
具体地，支撑板153朝向上板152和下板154的边缘设有卡接部1531，上板152和下板154嵌于卡接部1531之后通过螺丝实现上板152和下板154的固定连接。

第一轮轴1541和第二轮轴1542的设置使得第一传动齿轮1311和第二传动齿轮1312在轮架与下板154之间更加稳定，防止第一传动齿轮1311和第二传动齿轮1312相对于下板154沿第一传动齿轮1311和第二传动齿轮1312的轴向移动。
具体地，第一轮轴1541和第二轮轴1542可以采用精钢制成。精钢具有硬度高，耐磨性好的优点。因此，采用精钢制成的第一轮轴1541和第二轮轴1542寿命更加高，摩擦力更小。降低旋转机构10噪声的同时还能提高旋转机构10的使用年限。可以理解的是，第一轮轴1541和第二轮轴1542不仅仅可以采用精钢制成，可以根据不同情况采用不同的材料制成。例如，第一轮轴1541和第二轮轴1542可以采用铸铁制成。
具体地，第一轮轴1541上设有第三轴承15411和第四轴承15412，第一传动齿轮1311穿过第三轴承15411和第四轴承15412使得第一传动齿轮1311能够相对第一轮轴1541转动。第二轮轴1542上设有第五轴承15421和第六轴承15422，第二传动齿轮1312穿过第五轴承15421和第六轴承15422使得第二传动齿轮1312能够相对第二轮轴1542转动。第三轴承15411和第四轴承15412的高度小于第五轴承15421和第六轴承15422的高度。
进一步地，第一轮轴1541和第二轮轴1542与下板154一体成型。一体成型的结构更加稳定，能够防止第一轮轴1541或第二轮轴1542松动。当然，第一轮轴1541和第二轮轴1542还可以通过其他方式固定在下板154上。例如，第一轮轴1541和第二轮轴1542可以通过螺 丝固定在下板154上。
具体地，底盖142与下板154通过螺丝实现固定连接。当然，下板154不仅仅可以通过螺丝与底盖142连接。可以根据不同情况采用不同的连接方式。例如，下板154还可以采用粘胶粘在底盖142上。
更进一步地，上板152上设有连接孔1521，第一轮轴1541和第二轮轴1542均穿过连接孔1521且部分位于连接孔1521外。第一轮轴1541和第二轮轴1542位于连接孔1521外的部分设有第一外螺纹16。第一轮轴1541和第二轮轴1542通过螺母与第一外螺纹16实现与上板152的连接。
具体地，外壳141上设有第一通孔1411，上板152上设有第二通孔1522，下板154上设有第三通孔1543，底盖142上设有第四通孔1421。第一通孔1411、第二通孔1522、第三通孔1543、第四通孔1421同轴设置。第一刀轴11和第二刀轴12均穿过第一通孔1411、第二通孔1522、第三通孔1543、第四通孔1421且第一刀轴11的两端均位于第一通孔1411和第四通孔1421外。第二刀轴12与第一通孔1411连接处设有第一防水圈17，第一防水圈17可以防止水进入第一通孔1411中造成第一刀轴11的损坏。
在一个例子中，第一刀轴11伸出第四通孔1421的一端设有对接头113，对接头113用于与外界电机连接以通过外部电机带动第一刀轴11转动。
具体地，第一刀轴11与底盖142之间设有第七轴承18，第一刀轴11通过第七轴承18实现与底盖142转动连接。
请参阅图2和图3，在某些实施方式中，旋转机构10包括第一搅拌刀111和第二搅拌刀121，第一搅拌刀111安装于第一刀轴11，第二搅拌刀121安装于第二刀轴12。
第一搅拌刀111和第二搅拌刀121的设置，能够使得旋转机构10能够将食物充分的切割粉碎。
具体地，第一搅拌刀111和第二搅拌刀121采用精钢制成。精钢具有硬度高，表面光滑的特点。因此，采用精钢制成的第一搅拌刀111和第二搅拌刀121硬度更加高，能够使得食物充分粉碎。可以理解的是，第一搅拌刀111和第二搅拌刀121不仅仅可以采用精钢制成。可以根据不同的需求采用不同的材料制成。例如，轮架可以铁合金制成。
进一步地，外壳141上设有凹槽1412，第二搅拌刀121朝向凹槽1412弯曲，如此设置，能够使得掉落在凹槽1412内的食物被充分粉碎，提升旋转机构10粉碎食物的效率。
请参阅图8和图9，在一个例子中，第一刀轴11远离壳体14的一端设有内螺纹114，第一搅拌刀111穿过内螺纹114之后通过螺钉固定连接。
更进一步地，第二刀轴12远离壳体14的一端设有第二外螺纹126，第二搅拌刀121穿过第二外螺纹126通过螺母进行连接。进一步地，第一搅拌刀111与第一刀轴11之间设有第二防水圈19，第二防水圈19可以防止水进入螺母中造成螺母的损坏。
具体地，壳体14内设有第八轴承20，第八轴承20位于第一防水圈17下方，第二刀轴12通过第八轴承20实现相对壳体14的转动。
进一步地，第一刀轴11上设有环形设置的第一凸缘115，第一凸缘115对立设有第一开口1151，第一中心齿轮112上对立设有第一凸台1121，第一凸台1121嵌与第一开口1151以使第一刀轴11和第一中心齿轮112稳定连接。由于第一凸台1121嵌与第一开口1151，因此在第一中心齿轮112转动时候能够带动第一刀轴11转动。
更进一步地，请参阅图10和图11，第二刀轴12上设有环形设置的第二凸缘127，第二凸缘127对立设有第二开口1271，第二中心齿轮122上对立设有第二凸台1221，第二凸台1221嵌与第二开口1271以使第二刀轴12和第二中心齿轮122稳定连接。由于第二凸台1221嵌与第二开口1271，因此在第二中心齿轮122转动时候能够带动第二刀轴12转动。
具体地，第一中心齿轮112上设有第一螺孔21，第一凸缘115上设有与第一螺孔21配合的第二螺孔22。第一中心齿轮112通过第一螺孔21和第二螺孔22与第一刀轴11固定连接。

在某些实施方式中，第一搅拌刀111与第二搅拌刀121的转动方向相反。
转动方向相反能够使得食物粉碎更加充分。
请参阅图12和图13，本申请提供一种食物处理器100，食物处理器100包括上述任一项实施方式的旋转机构10和电机1011。电机1011连接第一刀轴11。电机1011用于驱动第一刀轴11转动。
本申请实施方式的食物处理器100的旋转机构10的齿轮传动结构13的第一传动齿轮1311和第二传动齿轮1312分别和第一中心齿轮112和第二中心齿轮122啮合，通过第一传动齿轮1311和第二传动齿轮1312来驱动第一中心齿轮112和第二中心齿轮122转动，如此能够使得第一中心齿轮112和第二中心齿轮122转动更加高效，从而提升第一刀轴11和第二刀轴12的转动效率。
具体地，食物处理器100还包括底座101和杯座102，电机1011设于底座101，旋转机 构10位于杯座102内，对接头113位于杯座102外，电机1011与对接头113连接之后驱动第一刀轴11转动。
具体地，电机1011工作带动第一刀轴11转动，由于第一搅拌刀111与第一刀轴11固定。因此，第一搅拌刀111也会随着第一刀轴11的转动而转动。第一刀轴11转动还会带动第一中心齿轮112转动，第一中心齿轮112转动使得第一传动齿轮1311、第二传动齿轮1312、第二中心齿轮122转动。由于第二刀轴12与第二中心齿轮122固定连接。因此，第二刀轴12也会随之转动。由于第二搅拌刀121和第二刀轴12固定。因此，第二搅拌刀121也会随着第二刀轴12的转动而转动。如此，在电机1011驱动第一刀轴11转动之后可以使得第一搅拌刀111和第二搅拌刀121转动，通过第一搅拌刀111和第二搅拌刀121转动来将食物切割和粉碎。
进一步地，食物处理器100可以为破壁机，通过旋转机构10来将食物进行粉碎。可以理解的是，食物处理器100还可以为其他需要利用旋转机构10来将食物进行粉碎的机器。例如，食物处理器100可以为榨汁机或者搅拌机等。
