本发明的目的主要是提供一种带有安全保护装置的食物处理器， 能有效防 止食物飞溅， 避免食物处理机零部件误操作时的损坏， 同时结构简单， 加工方 便， 适于大规模的生产。
本发明的另一目的是提供一种大料口食物处理器， 具有大放料口和小放料 口， 增大了食物放入切片或切丝刀盘时的入料口尺寸， 能够实现大尺寸食物不 必预先切成较小片也可以直接放入， 用户可以根据食物的大小选择装料口， 这 样方便了用户对料理机的使用。
本发明为达到上述目的所采用的具体技术方案是： 一种带有安全保护装置 的食物处理器， 包括设置有动力单元的基座， 所述基座上设有一内设有刀具的 杯体， 所述杯体上设有杯盖和手柄， 所述手柄内设有连杆以及与连杆相配的连 杆复位弹簧， 所述杯盖上设有与连杆上部相配的触压部， 所述基座内设有与连 杆下部相配并可上下移动的开关支架以及与开关支架相配的支架复位弹簧， 所 述开关支架下部设有控制动力单元启闭的保护开关， 所述保护开关上设有与开 关支架相配的开关触点。 本发明在杯盖打开或者杯体离开基座时， 会自动给动 力单元断电； 同时在切削食物时， 只有杯盖处于盖合的状态， 动力单元才能正 常启动， 本发明具有较高的安全性。 本发明通过杯盖的触压部与连杆、 连杆与 开关支架、开关支架与开关触点的触压配合来控制动力单元回路的接通与关闭。 当杯体盖合时， 杯盖上的触压部与连杆接触并将连杆下压， 连杆带动基座上的 开关支架下行， 开关支架触动保护开关的触点， 从而接通动力单元回路； 当杯 盖打开时， 连杆失去压力， 通过连杆复位弹簧回弹至原位， 此时开关支架也失 去压力， 通过支架复位弹簧回位， 开关支架与开关触点分离， 动力单元回路断 开； 同样， 当将盖有杯盖的杯体从基座上抬起时， 开关支架与开关触点分离， 动力单元回路同样也断开。
作为优选， 所述杯盖上设有卡钩， 所述卡钩包括与杯盖相连的卡钩连接部 以及卡钩连接部下部一体成型的斜面部， 所述触压部为该斜面部。 触压部采用 斜面， 能保证触压部与连杆紧密压牢。
作为优选， 所述手柄上设有一连杆槽， 所述连杆设置在连杆槽内。
作为优选， 所述连杆包括与所述触压部相配的上压块部、 与所述开关支架 相配的下压杆部以及连接上压块部和下压杆部的连接杆部， 所述连接杆部和上 压块部之间设有导块部， 所述导块部与所述连杆槽的内壁滑动接触。 上压块部 与触压部触压配合， 下压杆部于开关支架触压配合， 导块部起滑移导向作用， 能防止连杆在滑动过程偏向。
作为优选， 所述连接杆部包括上连接杆部、 下连接杆部以及连接两者的折 部。 折部的设置使得连接杆部具有一定的安装韧性， 使得安装方便。
作为优选， 所述上连接杆部的轴心线与下连接杆部的轴心线平行。
作为优选， 所述连杆槽下部设有与连杆相配的连杆孔， 连杆槽与所述连杆 孔相贯通， 所述下压杆部和连接杆部之间设有与连杆孔相配的挡块部， 所述连 杆复位弹簧套设于所述挡块下端的下压杆部。 挡块部的设置是防止连杆向下位 移过大， 有效地保护了保护开关， 延长了开关使用寿命。
作为优选， 所述保护开关为微动开关， 所述基座内固定有开关底座， 所述 微动开关固定在开关底座上， 所述开关触点上连接有弹片， 所述弹片与设置在 所述开关支架上的压块相配， 所述杯盖周缘设有若干锁扣。 本发明通过压块触 压弹片将开关触点下压， 从而打开微动开关， 接通动力单元回路。
本发明的食物处理器采用大料口的结构时， 所述杯体的杯口处设有大口径 支架， 所述大口径支架包括有一与杯体内相贯通的大料口， 所述杯盖上设有一 压盖所述大料口的挡片， 所述挡片上设有大推料杆孔和入料孔， 所述挡片上压 盖有大推料杆， 所述大推料杆上设有与入料孔相对应的小推料杆口和与大推料 杆孔相配的推杆，所述小推料杆口内压盖有封闭小推料杆口的杆状的小推料杆， 所述保护开关为微动开关， 微动开关上设置有开关触点， 所述开关触点上连接 有弹片， 所述弹片与设置在所述开关支架上的压触点相配。 本发明通过杯盖的 触压部与连杆、 连杆与开关支架、 开关支架上的压触点与弹片的触压配合来启 闭微动开关， 从而控制动力单元回路的接通与关闭； 当杯体盖合时， 杯盖上的 触压部与连杆接触并将连杆下压， 连杆带动基座上的开关支架下行， 开关支架 上的压触点通过弹片触压微动开关上的开关触点下行， 启动微动开关， 从而接 通动力单元回路； 当杯盖打开时， 连杆失去压力， 通过连杆复位弹簧回弹至原 位， 此时开关支架也失去压力， 通过支架复位弹簧回位， 开关支架与弹片分离， 开关触点回位， 微动开关关闭， 使得动力单元回路断开； 同样， 当将盖有杯盖 的杯体从基座上抬起时， 开关支架与弹片分离， 动力单元回路同样也断开。 本 发明杯盖上的挡片将大口径的大料口转换成两个较小的开孔， 减少了大料口的 截面积， 也直接避免了安全问题； 推杆用以直接推压食物； 所述小推料杆压盖 在大推料杆上， 并穿过大推料杆挤压食物； 本发明方便大尺寸食物的切丝或切 片功能， 在需要大尺寸食物切屑时， 取出杯盖， 动力单元回路自动断开了， 此 时将食物放入大口径支架的大料口内， 再合上杯盖， 杯盖上的触压部再触动整 个开关， 动力单元回路恢复接通， 小尺寸的食物只需拔出小推料杆， 将食物从 小推料杆口放入即可。
作为优选， 所述杯体内设有切削刀及盘状的刀盘， 所述动力单元为带动切 削刀及刀盘转动的电动马达， 所述大推料杆上包括有与入料孔相配的并与杯体 内贯通的大料筒， 所述大料筒的上部筒口为所述小推料杆口。
作为优选，所述基座内固定有开关底座，所述微动开关固定在开关底座上， 所述杯盖周缘设有若干锁扣。
作为优选， 所述大料口为椭圆形口。 本发明的大料口大过普通的料理机的 进料口， 这样大尺寸食物不必预先切成较小片也可以直接放入， 方便切屑大尺 寸的食物。
大料口结构食物处理器的其他结构及工作原理与前述食物处理器基本一 致， 这里不再赘述。
本发明的有益效果是： 本发明具有自动断电保护功能， 能有效防止食物飞 溅， 避免食物处理机零部件误操作时的损坏， 同时结构简单， 加工方便， 适于 大规模的生产； 同时本发明还设置有大小食物都可以直接放入的结构， 用户可 以根据食物的大小选择， 这样方便了用户对料理机的使用。
