在本实施例中 ， 下壳 220，上靠近上壳 210，一側的側面设有第二定位柱 222，， 可在从动齿轮組 252，的中央设置螺钉孔，通过螺钉穿过从动齿轮組的螺钉孔将从 动齿轮組 252，固定在第二定位柱 222，上， 即从动齿轮組 252，固定在下壳 220，上靠 近上壳一側的側面 ， 即从动齿轮組 252'位于上下壳 210'、 220'之间的空隙处。从 动齿轮組 252'包括同轴转动的上从动齿轮 252a'和下从动齿轮 252b'，上从动齿轮 252a'与下传动齿轮 251b'相配合，下从动齿轮 252b'与从动轴 253'上端设置的从动 轴齿轮 253b'相配合。 同样可根据需要将第二定位柱 222'设置在上壳 210'上， 再 将从动齿轮組 252，套设在第二定位柱 222，上；也可将从动齿轮組 252，按照传动齿 轮組的定位方式套设在第二定位柱 222，上。
如图 4 所示，在上、下壳 210，、 220，組合形成的滑槽 231，中 ，滑槽壁上开设 设有缺口 231a， ， 以供位于上、下壳 210、 220 之间的上传动齿轮 251a，穿过缺口 231a'到达滑槽 231 '内与滑槽内位于拉杆側面的齿条 235'啮合配合。拉动拉杆 233' 时 ，拉杆 233'側面的齿条 235 与传动齿轮組的上传动齿轮 251a'啮合， 带动传动 齿轮組 251 '转动 ； 传动齿轮組的下传动齿轮 251b'与从动齿轮組的上从动齿轮 252a'啮合，带动从动齿轮組 252'转动 ；从动齿轮組的下从动齿轮 252b'与从动轴 上的从动轴齿轮 253b，啮合，带动从动轴 253，转动，从而驱动食物处理組件 300 转 动 °
为了在往复拉动拉杆 233'时，从动轴 253'能够始终朝向一个方向转动，优选在传 动机构中设置离合机构 410。本实施例将离合机构 410 设置在传动齿轮組 251 '中 。 具体地，如图 5a、5b、6a、6b、6c所示 ，离合机构 410 包括设置在上传动齿轮 251a' 和下传动齿轮 251b'之间的拨动轮 411 和棘爪 412。为了将拨动轮 411 和棘爪 412 限位在上传动齿轮 251a'和下传动齿轮 251b'之间 ，在上、下传动齿轮 251a'、 251b' 之间设置容置腔，拨动轮 411和棘爪 412 都设置在容置腔内 。在本实施例中 ，棘 爪 412 的数目为三个，但可根据需要设置为一个、 两个或更多个。
具体地，在本实施例中 ，上传动齿轮的下端面设有向下凸起的环形柱面 414， 下传动齿轮的上端面开设有凹槽 415，将环形柱面 414 和凹槽 415 配合在一起形 成容置拨动轮 411和棘爪 412的容置腔。拨动轮 411四周设有拨动坱 411a且中心设 有中心孔 416，在本实施例中拨动坱 411a的数量为三个， 分别周向均布在拨动轮 411 四周 。在环形柱面 414 内部为与拨动轮 411 轮廓相匹配的限位槽 413， 限位 槽 413中心位置处设有与拨动轮中心孔 416相配合的定位柱 418， 当拨动轮的中心 孔 416 套设在限位槽中心的定位柱 418 上时 ，拨动轮 411 能够绕定位柱 418 中 心转动一定角度。
下传动齿轮的凹槽 415 为圆形凹槽，凹槽 415 的圆弧面上均布设有棘齿 419， 从而在凹槽内形成棘轮槽 415a。上传动齿轮的环形柱面 414 上开设有缺口 414a， 供设置在限位槽内的棘爪 412 从限位槽 413内伸出与棘轮槽上的棘齿 419 配合。 限位槽 413 槽底设有与棘爪 412 上突起设置的转轴 412a相配合的定位孔 413a (见 图 6c ) ， 用于将棘爪 412 定位在限位槽 413 内 ；拨动轮的每个拨动坱 411a 与限 位槽槽底相接触的端面上设有凸柱 411b， 限位槽槽底开设有与该凸柱相配合的 圆弧槽 413b，凸柱 41 lb 能绕拨动轮 411 的转动中心在圆弧槽 413b内转动一定的 角度，该转角的大小由圆弧槽 413b 的弧度决定。
如图 6a、 6c所示 ， 当上传动齿轮 251a'转动时 ，上传动齿轮 251a'通过棘爪的 转轴 412a与限位槽的定位孔 413a的配合带动棘爪的转轴 412a同步转动 ，使得棘爪 的转轴 412a朝向拨动轮的拨动坱 41 la移动 ；此时拨动轮的凸柱 41 lb不动而上传动 齿轮的限位槽槽底开设的圆弧槽 413b 随上传动齿轮 251a'—同转动 ， 即圆弧槽 413b 相对凸柱 411b 滑动 ， 这使得凸柱 411b 与棘爪转轴 412a 之间的距离逐步 缩短，拨动坱 411a 推动棘爪 412 绕着棘爪的转轴 412a 自转，从而将棘爪 412 向 环形柱面 414 的外側推，使得棘爪 412 卡入棘轮槽的棘齿 419上，从而带动下传 动齿轮 251b'转动。 此时 ， 离合机构 410 处于合拢状态 ，使得上传动齿轮 251a' 能够带动下传动齿轮 251b'同步转动。
如图 6b、6d所示 ， 当上传动齿轮反向转动时 ，上传动齿轮 251a'通过棘爪的转 轴 412a 与限位槽的定位孔 413a 之间的配合带动棘爪的转轴 412a 同步反转，使 得棘爪的转轴 412a 朝向远离拨动轮拨动坱 411a 的方向移动 ；此时拨动轮的凸柱 411b 不动而上传动齿轮的限位槽槽底开设的圆弧槽 413b 随上传动齿轮 251a'— 同反转， 即圆弧槽 413a 相对凸柱 411b 反向滑动 ， 这使得凸柱 411b与棘爪转轴 412a 之间的距离逐步拉大，拨动坱 41 la 脱离棘爪 412，棘轮槽的棘齿 419 能够 拨动棘爪 412 绕着棘爪 412a 转轴反转，使得棘爪 412 脱离棘齿 419。 此时 ， 离 合机构 410 处于脱离状态 ，使得上传动齿轮 251a'不能带动下传动齿轮 251b'转 动 °
通过上述离合结构 ，使得拉杆 233'在往复运动过程中 ，齿条 235'在单向滑动 时能够带动上传动齿轮 251a'通过自动合拢的离合机构 410 带动下传动齿轮 251b，同步转动，从而驱动从动齿轮組 252，带动从动轴 253，转动；而齿条 235，在反 向滑动时 ， 离合机构 410 能够自动脱离 ，使得上传动齿轮 251a'反转， 而下传动 齿轮 251b'在原有转动惯性的作用下保持原有的转动方向 ，从而保证整个小型食 物处理器能够继续保持有效的工作。 而离合机构 410 的自动离合使得操作非常 方便。
上述离合机构 410也可根据需要设置在从动齿轮組 252'中 ，如将离合机构 410 中 的拨动轮 41 1 和棘爪 412 设置在上从动齿轮 252a'和下从动齿轮 252b'之间形成 的容置腔内 。

如图 3、 3a 所示 ，在本实施例中 ，所述去水篮組件包括同步转动设置在从动 轴 253 '下端的去水篮盖 361和转动定位在容器内的去水篮 362，去水篮盖 361固定 在去水篮的敞口处。具体地，去水篮盖 361和去水篮 362 之间可通过扣合结构固 定在一起，去水篮盖 361 的中心位置设有中心孔 361a，从动轴 253'下部设有扁方 段 253d'，中心孔的形状与扁方段 253d'相匹配，从动轴的下端设有锁紧螺母 259'。 将去水篮盖的中心孔 361a套设在从动轴的扁方段 253d，上，再利用锁紧螺母 259， 将去水篮盖 362 锁紧在从动轴 253 '下端 ，使得去水篮盖 361 能够固定在从动轴 253，下端并能随从动轴 253，同步转动。去水篮 362 的底部中心位置处设有凹陷部 (图中未示出） ， 容器底部的中心位置处设有与去水篮底部凹陷部相匹配的突 起（图中未示出） 。当去水篮底部放置在容器底部时 ，从动轴 253'能够通过去水 篮盖 361 带动去水篮 362 绕中心轴转动 ，从而能够将去水篮 362 内的食物的水 甩出 ， 达到去水的目的。
本实施例的食物处理組件 300并不只有去水篮組件，还可配有刀片組件。如 图 1、 3b所示 ，在本发明所述的小型食物处理器的刀片組件中 ， 包括套接在从动 轴下部的连接轴 255、同轴设置在连接轴下端的中心轴 310 和设置在中心轴上的 刀片 340。其中 ，连接轴 255 的上方与从动轴的下部同轴设置， 即连接轴 255 与 从动轴固定连接， 具体地可在连接轴 255 的上端设置与从动轴下部的相配合的 螺紋孔。 中心轴 310的顶端设有与连接轴 255底端相配合的第一中心孔 311。优选 设置连接轴 255 的下部为六边形柱体 255b， 中心轴的第一中心孔 311 为与从连 接轴 255 部的六边形柱体 255b相匹配的六边形中心孔，使得从动轴 253'能够通过 连接轴 255 带动中心轴 310 同步转动。 中心轴 310 的底端设有沉孔 （图中未示 出） ，容器 100 内側的底部正对于连接轴 255 下方的位置设有凸轴 113(见图 10 )， 中心轴底端的沉孔与凸轴 113 配合， 能够将中心轴 310的下端转动定位在容器 100 底部。根据需要也可设置从动轴直接与中心轴的上端连接，使得从动轴直 接驱动中心轴与从动轴同步转动。
在中心轴 310 的四周还设有连接片 330， 连接片 330 是从中心轴的柱面向四 周延伸形成，连接片 330 上设有定位突起 331 ，刀片 340 的端部设有与定位突起 331 相配合的定位孔 341 ， 将刀片的定位孔 341 套设在连接片 330 的定位突起 331 上，再利用螺钉等紧固件将刀片 340 锁紧固定在连接片 330 上，使得刀片 340随中心轴 310 转动。根据需要，在中心轴的柱面上设置多个刀片 340， 多个 刀片周向均布在中心轴的柱面上， 当中心轴带动多个刀片绕容器的中心轴转动 时，刀片能对容器内的食物进行切削处理。

拉杆組件包括上壳 210 的上表面 （即容器盖組件 200 的顶部） 设置的滑槽 231、滑槽盖 232和拉杆 233。滑槽盖 232 和滑槽 231 相配合在上壳 210 的顶部形 成滑道，拉杆 233 与滑道相配合，使得拉杆 233能在滑道内沿水平方向往复滑动。 具体地，可利用螺钉 216 将滑槽盖固定在上壳 210 的上表面位于滑槽的位置处。 优选在拉杆 233 的一端设置手柄 234，手柄 234 与拉杆 233 通过销轴结构转动连 接在一起，其销轴最好设置为与拉杆 233 的滑动方向垂直且位于同一水平面内 ， 这样在握持手柄 234 水平方向拉动拉杆 233 时 ，手柄 234与拉杆 233 之间可以存 在一定的转动 ，操作起来不会感觉到呆滞，非常灵活。拉杆 233的一側側面设有 齿条 235， 与传动机构形成齿轮齿条配合，以便拉杆 233 能够驱动传动机构带动 食物处理組件转动。
如图 8、 9、 9a、 11所示 ，传动机构 250 包括传动齿轮組 251、从动齿轮組 252 和从动轴 253。其中 ， 下壳 220 上靠近上壳一側的側面设有第一定位柱 221 ，传 动齿轮組 251 的中央包括一个螺钉孔，通过螺钉穿过传动齿轮組的螺钉孔将传 动齿轮組 251 固定在第一定位柱 221 上，即传动齿轮組 251 固定在下壳 220上靠 近上壳一側的側面 ， 即传动齿轮組 251 位于上下壳 210、 220之间的空腔处。传 动齿轮組 251 上设有上传动齿轮 251a 和下传动齿轮 251b，上传动齿轮 251a与拉 杆 233側面的齿条 235相配合，下传动齿轮 251b与从动齿轮組 252相配合。

如图 8 所示 ，在上壳的滑槽 231 中 ，滑槽壁和滑槽盖 232 的对应位置处开设 有通孔 217a、 217b， 以供位于上下壳 210、 220之间的上传动齿轮 251a穿过通孔 217a、 217b到达滑道内与滑道内位于拉杆側面的齿条 235 啮合配合。拉动拉杆 233时，拉杆 233側面的齿条 235与传动齿轮組的上传动齿轮 251a啮合， 带动传动 齿轮組 251 转动 ； 传动齿轮組的下传动齿轮 251b 与从动齿轮組的上从动齿轮 252a啮合， 带动从动齿轮組 252转动 ； 从动齿轮組的下从动齿轮 252b 与从动轴 上的从动轴齿轮 253b 啮合， 带动从动轴 253 转动 ，从而驱动食物处理組件 300 转动。
为了在往复拉动拉杆 233 时，从动轴 253 能够始终朝向一个方向转动，优选 在传动机构中设置离合机构 410，离合机构 410 的具体结构可按照上述第一实施 例的离合机构 410 的结构设置。
在本实施例中 ， 同样可在下壳 220 的中心处设置轴孔 223 ，从动轴 253 转动 连接设置在该轴孔 223 处。从动轴下部穿过轴孔 223延伸至盖体下方与食物处理 組件相配合，从动轴的上部设有与下从动齿轮 252b 相啮合的从动轴齿轮 253b。
在本发明所述的小型食物处理器中 ，食物处理組件 300可分为多种具有不同 功能的組件，如刀片組件、搅拌組件、去水篮組件等 ，根据不同食物处理工艺 的需要可选用不同的功能組件安装在容器 100内 ， 以对容器 100内的食物进行不 同的处理。在本实施例中以食物处理組件 300 为搅拌食物的翼片組件为例进行 阐述。如图 12所示 ，翼片組件 300b 包括中心轴 310b和两片翼片 350，翼片 350 的 側边固定在中心轴 310b 的周面上，翼片 350可一体化成型制作在中心轴 310b 上 或通过紧固件固定在中心轴 310b 上。中心轴 310b的顶端设有与从动轴 253 底端 相配合的中心孔 （图中未示出） ，使得从动轴能够驱动中心轴与从动轴同步转 动。如果从动轴底端如第一实施例设置为螺紋，则中心孔设置为螺紋孔；如果 从动轴底端设置为六角形的扁方，则中心孔可设置为与该扁方相匹配的六角形 中心孔； 还可如上述第一实施例中的刀片組件中所述的一样，在从动轴和中心 轴之间增加一个连接轴，使得从动轴驱动中心轴同步转动。 中心轴的底端同样 可设有与容器 100内側底部设置的凸轴相配合的沉孔 312b。使用时，从动轴驱动 中心轴转动， 而翼片 350 随着中心轴 310b 转动 ，从而能够拨动容器 100 内的食 物，实现对食物进行搅拌的功能。
同样为了增加从动轴 253 转动时的惯性，在从动轴 253上也设有与从动轴 253 同步转动的配重坱 254。具体地，如图 8、 10、 10a、 1 1 所示 ，在第二实施例中 配重坱 254 优选设置为圆盘形状，最好采用密度较高的材料制成，以增加惯性。 连接轴 255的上端设有六边形的连接孔 255a，从动轴的下部设有与连接孔 255a相 匹配的六边形的柱体 253a而上端开设有螺钉通孔 253c，通过螺钉穿过从动轴的螺 钉通孔 253c 和连接轴 255 的上端螺紋连接，从而将从动轴 253和连接轴 255 定 位在下壳 220 的上下两側，而连接轴的连接孔 255a与从动轴的柱体 253a相配合限 制了从动轴 253和连接轴 255 之间的相对转动 ，这样就能将配重坱 254 固定在从 动轴 253 上，从动轴 253通过连接轴 255 驱动食物处理組件转动。连接孔 255a 和 柱体 253a 还可根据需要设置为其他多边形或异形 ，只要能够限制从动轴 253 和 连接轴 255 之间的相对转动即可。配重坱 254 同轴设置在连接轴 255 上，具体 地， 从动轴上部位于下壳的上側部分设有六边形的轴肩 255d， 配重坱中心设有 与轴肩 255d 相配合的六边形中心孔 254a，这样从动轴 253 转动时能够带动配重 坱 254转动，以此增减从动轴转动时的惯性。 同样，在上述第一实施例中 ，可将 配重坱同轴转动设置在从动轴的下部。
在上述实施例中 ，可在容器 100 的内壁表面包括沿容器 100 的轴线方向设置 的第一凸起 1 1 1 (见图 10 ) ， 即第一凸起 1 1 1 由容器 100内壁的顶部沿其内壁表 面向其底部延伸 ，该第一凸起 1 1 1 能够在食物处理組件 300 转动时增加食物处 理組件 300 和被切食物之间的阻力 ，从而使得食物的切碎效果更好。 第一凸起 1 1 1 的数目可设置为四根或更多根。在上述实施例中 ，还可在容器 100 的外表 面还可设有两个凹陷部 1 12，这两个凹陷部 1 12 对称分布在容器 100 的外表面 ， 方便使用者在使用时可单手握住整个容器 100，使得整个食物处理器被固定， 而 使用者可使用另一只手拉动拉杆組件 230，进行操作。另外， 由于凹陷部 1 12 的 存在，也可以方便使用者双手正反配合扭动 ， 以增加该小型食物处理器的切削 速度。在本实施例中 ， 由于上述两个凹陷部 1 12 内陷且突出于容器 100 的内表 面 ，所以该凹陷部 112 在一定程度上还具有加大被加工食物在容器 100 内阻力 的作用 。上述四条第一凸起 111 可分为两組，每組包括两条第一凸起 111 ，一組 中的第一凸起 111 分别以一个凹陷部 112 为中心均匀分布 ， 即上述每个凹陷部 112 的两边的对称位置上各设置有一条第一凸起 111 。
以上所述实施例仅表达了本发明的几种实施方式 ，其描述较为具体和详细，但 并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的 普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改 进，这些都属于本发明的保护范围 。 因此，本发明专利的保护范围应以所附权 利要求为准。
