Description

榨汁机
技术领域
本发明涉及厨房用具， 特别是涉及一种榨汁机。
背景技术
为了健康地生活，越来越多的人喜欢在家中直接制作和饮用蔬果汁液， 市场 上也因应出现了大量能够从蔬菜或水果中简单榨取汁液的装置。 目前，榨汁装置 主要有以下两种结构形式：
一种是高速离心式榨汁装置。这种榨汁装置是利用粉碎装置将待榨取汁液的 蔬果粉碎， 然后以高速旋转的方式利用离心力将汁液甩出。此种榨汁方式具有的 较大缺点是， 当遇到比较大的蔬果时需要人工切成小片后再投到入料端口， 然后 才能进行粉碎榨取汁液，这样操作起来比较费时间， 另外在高速粉碎蔬果以及分 离汁液的过程中， 蔬果中含有的固有味道和营养会被破坏， 并且会损失大量的植 物纤维。
另一种是螺杆挤压式榨汁装置。这种榨汁装置是利用螺杆结构挤压待榨取汁 液的蔬果， 从而将汁液分离出来。 此种榨汁方式的缺点是， 当遇到比较大的蔬果 时同样需要人工切成小片后再投到入料端口， 而且， 对电机的功率要求较大， 机 器寿命短。
综上， 现有榨汁装置均存在操作复杂， 耗费时间长的问题， 给消费者的使用 带来了不便。

参见图 1 , 本发明其中一个实施例中的榨汁机包括有： 底座 600、 驱动机构 400、 外壳 300、榨汁头 200、 切割刀具 500、 盖 100及过滤结构， 其中， 底座 600 用于支撑外壳 300, 在该底座 600的内腔中装有驱动机构 400, 驱动机构 400包 括有电机 410和减速器 420 (如图 3所示；)， 减速器 420的输出轴 421从底座 600 的顶盖竖直向上伸出与榨汁头 200连接。减速器 420用于减小电机 410的旋转速 里的固有味道和营养不受到破坏，榨取出来的汁液具有较高的营养价值。在底座 600的顶面上沿输出轴 421的周向设置有多个用以固定外壳 300的卡钩 610。
继续参见图 1 , 外壳 300为上端具有开口部 310的筒状结构， 优选地， 所述 外壳 300包括上部的下端小、上端大的锥形进料部 320和下部的下端小、上端大 的锥形榨汁部 330, 且进料部 320的锥度大于榨汁部 330的锥度。 本实施例的外 壳 300的进料部 320上端的直径大大的大于榨汁部 330上端的直径，如此，在不 增加榨汁头 200直径的情况下， 有利于较大体积的果蔬进入榨汁头 200与外壳 300之间的空间内， 同时有利于进入更多的果蔬， 提高榨汁效率， 而且， 由于不 需要增大榨汁头 200直径，因此驱动机构 400的电机 410可以釆用小功率的电机， 有利于降低制造成本。
外壳 300的底部形成有中空防水圆柱体 340、 环绕该防水圆柱体 340的环状 排渣平台 360以及形成于防水圆柱体 340与排渣平台 360之间的环状接汁槽 350。 防水圆柱体 340用于穿过输出轴 421。 接汁槽 350用于接收分离出来的汁液， 该 接汁槽 350与设置在外壳 300下端侧壁上的汁液出口 380连通。 排渣平台 360 包括内挡壁 361、 外挡壁 362以及形成于内挡壁 361与外挡壁 362之间的环状挡 渣凹槽 363 , 残渣出口 370的入口端位于所述外挡壁 362的上表面上。 优选地， 为了彻底将残渣排出， 外挡壁 362的上表面为沿圆周方向倾斜的斜面， 残渣出口 370设置在外挡壁 362的上表面的最低位置处。
优选地，所述榨汁部 330的内壁上设置有一条或多条沿轴向延伸的引导筋条 331和一条或多条沿轴向延伸的研磨筋条 332, 所述引导筋条 331与所述研磨筋 条 332间隔设置，且所述引导筋条 331上端的高度大于所述研磨筋条 332的高度。
优选地， 在开口部 310的外周侧面上形成有多个向外突出的固定凸筋 311。 优选地， 在外壳 300的外底面上形成有与卡钩 610配合的卡槽 390 (如图 3 所示）， 外壳 300通过该卡槽 390和该卡钩 610可拆卸地装配在底座 600上。
继续参见图 1 , 所述盖 100安装在所述外壳 300的开口部 310处且与所述外 壳 300形成工作腔， 盖 100的中部形成有旋转轴孔 120, 且在该盖 100上与旋转 轴孔 120偏心设置有进料入口 110。 优选地， 在盖 100的盖沿内侧设置有与固定 凸筋 311配合的固定凹槽 130, 所述盖 100通过该固定凹槽 130和固定凸筋 311 可拆卸地与外壳 300连接。
继续参见图 1 , 所述榨汁部分 290包括榨汁部分 290、 驱动机构连接部分和 旋转轴 210, 榨汁部分 290的外表面设置有沿螺旋方向延伸的螺旋凸筋 240, 本 实施例的过滤结构为设置在榨汁部分 290下部的中空圆筒状的过滤腔壁 291 , 且 在过滤腔壁 291上设置有多个滤孔，使得从磨碎的材料中榨取的汁液穿过该滤孔, 达到汁液与残渣分离的效果。优选地， 所述滤孔的孔径的尺寸大小由上往下逐渐 减小， 因为食材颗粒的大小由上往下逐渐减小。 过滤结构除了釆用本实施例的结 构之外，还可以釆用在榨汁部分 290与外壳之间设置一个滤筒， 同样可以起到分 离渣和汁的目的。
本实施例中的驱动机构连接部分为形成在过滤腔壁 291内的连接轴 230, 该 连接轴 230的下端设置有正六边形轴孔 231 ,所述输出轴 421穿过防水圆柱体 340 插入该轴孔 231内 （如图 2、 3所示 )。 榨汁部分 290与驱动机构 400的连接方式 除了釆用轴和孔配合之外，还可以釆用离合器和键连接等方式。旋转轴 210包括 横截面为正六边形的第一部分 211和横截面为圆形的第二部分 212,第二部分 212 的上端插入所述盖 100中心的旋转轴孔 120内 （如图 2、 3所示 )。
优选地， 在榨汁部分 290 的下端处向下凸出地设置有环状结构的挡渣筋条 220和位于所述挡渣筋条 220 内侧的环状挡汁筋条 250以及形成于该挡汁筋条 250与所述挡渣筋条 220之间的挡汁凹槽 260。 如图 3、 4所示， 挡渣筋条 220 插入到挡渣凹槽 363中， 防止残渣进入榨汁部分 290内部， 内挡壁 361插入该挡 汁凹槽 260中， 可以进一步防止残渣和汁液混合。
优选地， 在榨汁部分 290的螺旋凸筋 240的下端部设置有多个推渣块 270, 该推渣块 270用以将已传送到外壳 300的排渣平台 360上的残渣排出外壳 300 的残渣出口 370。
优选地，所述榨汁部分 290的下端设置有位于所述挡渣筋条 220外侧的一个 或多个推渣片 280, 该推渣片 280的位于榨汁部分 290旋转方向前侧的侧面为斜 面，且该推渣片 280的下端插入所述挡渣凹槽 363内， 通过推渣片 280将进入挡 渣凹槽 363内的残渣排出。
切割刀具 500设置在所述进料入口 110与所述榨汁部分 290之间，用于将较 大蔬果自动切割成小片。 如图 1、 5所示， 所述切割刀具 500包括刀盘 520和刀 片 510, 所述刀盘 520包括内轮毂部 521、 外轮毂部 522和位于内轮毂部 521与 外轮毂部 522之间的盘体部 523 ,所述内轮毂部 521设置有正六边形刀盘轴孔 524, 该刀盘轴孔 524与所述旋转轴 210的第一部分 211配合，在所述盘体部 523上设 置有两个沿径向延伸的缺口， 所述缺口旋转方向前侧和后侧的所述盘体部 523 的端部分别为前端部和后端部，所述切削切割刀具 500固定在所述后端部的上表 面上。 通过调节刀片 510与盘体部 523之间的距离即可调节切削量。
优选地， 榨汁机还包括安全保护装置， 如图 3所示， 安全保护装置包括触动 杆 140、开关连杆 440、开关连杆固定架 450及设置在底座 600上的微动开关 460 , 其中触动杆 140设置于盖 100的端面上， 开关连杆固定架 450 固定在外壳 300 的外侧面上， 开关连杆 440位于开关连杆固定架 450内， 动开关 460安装在底 座 600顶面上触动槽 430位置装有^:动开关 460以控制电路的通断。
下面描述根据本发明的以上实施方式构造的榨汁机的操作原理。
食物材料从盖 100的进料入口 110进入到切割刀具 500中的切割刀具 500后， 食物材料被旋转着的切割刀具 500中的刀片 510在低速旋转作用下不断地切割成 若干小片， 然后进入到榨汁部分 290中， 在旋转的榨汁部分 290和引导筋条 331 以及研磨筋条 332的共同作用下被强制向下运送的同时得以精细的磨碎及压榨。 并汇集在外壳 300底部的接汁槽 350, 通过汁液出口 380排出外壳 300, 而残渣 则从残渣出口 370排出。
正如从前述中可见的， 根据本发明的榨汁机具有下面的效果：
1、 相对于高速离心式榨汁机的榨取方式， 本发明以预处理方式用切割刀具 将蔬果全自动切割成若干小片后再用榨汁头以很低的速旋转挤压的方式挤榨取 代传统的用手工将蔬果切割成若干小片后再投进入料端口使用高速旋转挤压的 方式挤榨，食材中包含的各种营养和固有味道最大限度地得到保持， 并有可能进 行广泛的汁液榨取而与蔬菜和水果的种类无关。
2、 本发明的榨汁机， 刀盘上装有锋利的刀片， 可以将较大的蔬果先进行预 处理全自动切割成若干小片， 从而解放了人们的劳动， 节省了时间。
3、 本发明的榨汁机， 榨汁头和滤网合二为一， 减少了部件数量， 结构更为 简单， 更易于生产制造。
4、 本发明的榨汁机， 榨汁头釆取了中空的设计， 节省了原材料， 降低了成 本。
5、 本发明的榨汁机， 取消了现有技术中工作腔内齿轮传动等复杂机构， 减 少了部件数量， 更易于生产制造。
6、 本发明的榨汁机， 由于减少了部件数量， 消除了因工作腔内齿轮传动带 来的振动和噪音，同时避免了因齿轮磨损导致磨损材料粉末进入汁液被人误食而 导致的潜在风险。
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。
