Description

滤网机构及其使用该滤网机构的果蔬榨磨机
技术领域
本发明属于果蔬加工设备领域，具体涉及一种用于果蔬榨磨机的滤网结构及其采用该滤网结构的一种果蔬加工机。
背景技术
现有的果蔬加工机，被使用在家庭中能制成多样的饮食品，其科学性和便利性被人们认识，其最大的贡献在于对人们的饮食健康起到积极作用。
现有机型的工作原理可以分为以下几种：（1）、卧式或立式螺旋挤压，如原汁机、果蔬机等。（2）、十字刀架粉碎型，如豆浆机、搅拌机和料理机等。（3）、棘齿刀盘磨制型，如榨汁机、橙汁机等。由于在产品的功能上存在结构性工艺设计问题，使得以上各种现有机型在实际使用中功能上都存在如下问题：
1、以现有豆浆机、搅拌机为例：基于采用十字刀架的粉碎原理，果蔬浆在高速转动下加水搅拌而产生混合型泡沫，以致原浆氧化。所以这类机型尤其在缺少过滤的情况下，严重影响了饮品的质量和导致天然醇味的流失。
2、以现有榨汁机为例：基于采用棘齿刀粉碎原理，在高速转动和离心过滤时会产生原浆氧化现象。进一步的，其结构使得杂质易阻塞网孔，导致未经过滤的果浆被抛出网外，从而降低了榨汁率，浪费原料。
3、以现有果汁机、果蔬机为例：基于采用螺杆挤压原理，在不切削的情况下对果物压榨，即在未有效的切断植物纤维前提下粉碎或压榨，在榨出果汁的同时，也破坏了果质原浆（即细胞体）。因此降低了果质原浆的营养成分。同时，在螺旋杆与固定滤网的强制性挤出过滤中，未经切断的纤维易阻塞网孔。
发明内容
针对上述背景技术中存在的问题，本发明提供了一种果汁原浆不易氧化，网孔不易阻塞且可以榨汁磨浆一体化的一种果蔬榨磨机。
本发明采用如下技术方案：一种用于果蔬榨磨机的上滤网，上滤网内壁上设置有若干个刀片，所述上滤网内壁上的每一个刀片均呈片状，且都是一面贴合在滤网内壁上，另一面呈不光滑磨面。
本发明的用于果蔬榨磨机的上滤网上的刀片的刀刃面位于刀片的左侧边或右侧边。所述上滤网呈圆锥筒状。每一个刀片的侧边与上滤网的圆锥筒母线呈倾斜角设置。每一个刀片的侧边与上滤网的圆锥筒母线之间的倾斜角为30度到60度。刀片的不光滑磨面为设置有锉齿的磨面。
本发明的滤网机构包括上滤网和下滤网，上滤网和下滤网之间还设置有中圈网，中圈网上固定有一遮挡圈，遮挡圈上设置有若干缺口，所述缺口处为中圈网网孔区域，且中圈网孔孔径分别大于上滤网网孔和下滤网网孔。
所述遮挡圈上连接有一中圈架，中圈架上对应设置有若干与遮挡圈上缺口配合的窗口；中圈架旋转套设在遮挡圈上。
所述中圈架上设置有一锁紧螺栓，对应的遮挡圈上设置有一滑槽；锁紧螺栓随着中圈架沿着滑槽滑动，并锁止在滑槽两端的位置处。
所述上滤网固定在滤网架上，滤网架上固定有若干个清网片；中圈架连接在滤网架的下方，且中圈架上设置有径向突出的若干个中圈耳，清网片延伸至中圈耳下方。
所述下滤网连接在中圈网下方。
本发明的果蔬榨磨机，包括电机底座和机头，电机底座上方凸设有一电机轴，
电机底座上方设置有磨浆过滤装置，所述磨浆过滤装置包括滤网机构和螺杆传动机构：
所述滤网机构包括上滤网、中圈网、遮挡圈、下滤网、滤网架和中圈架；上滤网固定在滤网架上，中圈架连接在滤网架的下方，中圈网上固定有一遮挡圈，中圈网通过遮挡圈连接在中圈架上，下滤网连接在中圈网下方；上滤网内壁设置有若干个刀片，每个刀片均呈片状，且每一个刀片的其中一个表面贴合在上滤网内壁上，另一个表面呈不光滑磨面；遮挡圈上设置有若干缺口，所述缺口处为中圈网网孔区域；中圈架上对应设置有若干与遮挡圈上缺口配合的窗口；中圈架内壁上设置有一锁紧螺栓，对应的遮挡圈上设置有一滑槽；锁紧螺栓沿着滑槽滑动，并锁止在滑槽两端位置处；滤网架上固定有若干个清网片，中圈架上设置有径向突出的若干个中圈耳，清网片延伸至中圈耳下方；滤网架上方还连接有一内齿轮，内齿轮上方设置有与内齿轮配合的传动机构，所述传动机构用来控制滤网架的转动；机头内还设置有与内齿轮配合的定位机构，所述定位机构用来控制滤网架的锁止；
所述螺杆传动机构包括螺杆和中心轴，中心轴与螺杆连接，螺杆与电机轴连接；螺杆呈上小下大的纺锥型球体，且球体外表面上设置有呈螺旋线状的凸条；螺杆的中心轴与上滤网的中心轴重合，且螺杆边缘与上滤网、中圈网和下滤网内壁之间均设有间隙，果物在间隙中随螺杆转动而被处理。
所述控制滤网架转动的传动机构包括套设在中心轴上的压簧、一对离合齿轮、一对二级变速传动齿轮和咬合齿轮；中心轴的并列位置处还设置有一滑杆，滑杆上设置有一压簧，压簧下方设置有一拔叉；拔叉的一端固定在滑杆上，即压簧的下方，另一端套在其中一个离合齿轮的轮颈上；滑杆的末端设置有一个滑轮，滑轮紧靠在离合凸轮顶端上，滑轮随着离合凸轮的摆动推动拔叉上下运动；一对离合齿轮咬合后，一对二级变速传动齿轮构成二级变速系，再经咬合齿轮与滤网架上的内齿轮咬合后使滤网架转动。
所述控制滤网架锁止的定位机构包括锁定轮、压簧片、凸轮和凸轮手柄；锁定轮设置在凸轮的下端，且所述锁定轮呈月牙形，随着凸轮的摆动可以嵌入内齿轮内锁止内齿轮转动；压簧片14固定在机身上，且紧靠住锁定轮的轮廓边，对锁定轮的锁定起到止动作用。
所述控制滤网架锁止的定位机构包括定位销、压簧和连杆：连杆通过一转轴固定在机身上，且连杆可绕转轴转动；连杆的一端套设在滑轮上，另一端套设在定位销上；定位销上套设有一压簧，压簧的一端被机壳压住，另一端被套设在定位销上的连杆压住，可在压簧的作用下嵌入内齿轮端面上的卡槽中。
本发明具有如下有益效果：由于本发明的果蔬榨磨机的磨浆过滤装置采用了石臼与石磨盘的两种原理的互溶方法，打破传统机构中滤网结构采用滤网和刀分开相互作用的方式，将刀和滤网固定在一起，让位于滤网中间的呈纺锥型球体的螺杆来带动果物在滤网与螺杆的间隙内运动。从而使果物在滤网内壁上的刀片上进行榨汁或磨浆。同时为了使榨磨过程中的切削和打磨效果更进一步，还可以同时让滤网和螺杆反向运动。这种切削和打磨方式下果浆不需要作高速转动或离心过滤，不容易导致原浆氧化。这种切削和打磨方式也不需要对果物进行压榨，也不会破坏果物细胞体，大大保持了果质原浆的营养成分。且果物纤维经过滤网上刀片的刀刃切削，不易阻塞网孔。
更进一步的，由于在滤网机构中设置了中圈网结构，且中圈网网孔比上滤网和下滤网的网孔都要粗。且经磨制的果蔬浆在进入压榨的前期得到过滤。使用者可以通过打开或者关闭中圈网网孔区域，来改变果浆或果汁的精细程度。当中圈网网孔打开时，榨磨之后的较粗物质可以从中圈网的粗网孔区域透出，从而使得果浆或果汁中具有粗颗粒物质。反之，关闭中圈网粗网孔区域，就可以使得果浆进入后期的压榨过滤，果汁不具有粗颗粒物质。

具体实施方式
如图6所示，本发明的用于果蔬榨磨机的滤网机构包括上滤网15和下滤网17，上滤网15和下滤网17之间还设置有中圈网23。如图5所示，中圈网23上固定有一遮挡圈33，遮挡圈33上设置有若干缺口331，所述缺口331处为中圈网网孔区域，且中圈网网孔孔径分别大于上滤网网孔和下滤网网孔。遮挡圈33上还连接有一中圈架2，中圈架2上对应设置有若干与遮挡圈33上缺口331配合的窗口231。如图4所示，中圈架2旋转套设在遮挡圈33上。且中圈架2上设置有一锁紧螺栓39，对应的遮挡圈33上设置有一滑槽38。锁紧螺栓39可随着中圈架2的转动而在滑槽38内滑动。当锁紧螺栓39滑动到滑槽38一端时，例如滑动到如图5所示的滑槽38左端，即滑动到中圈架2指示条的0端方向时，可以拧紧锁紧螺栓，将中圈架2锁止在该处。
如图6所示，滤网架8上固定有3个清网片，当然实际使用时也可以固定1-3个清网片（甚至更多，数量可以根据需要调整）。中圈架2连接在滤网架8的下方，且中圈架2上设置有径向突出的3个中圈耳22（中圈耳的数量也可以根据需要调整），每个清网片1均延伸至中圈耳22下方。
如图1、图2和图3 所示，本发明的一种用于果蔬榨磨机的滤网机构中的上滤网结构，包括上滤网15 和刀片13。上滤网15 内壁上设置有三个刀片13。这里的刀片13 可以根据需要来设置个数，并不限定三个。即可以根据需要设置成四个或五个，甚至更多个。所述三个刀片13 中的每个刀片13 均呈片状，且刀片13 的其中一个表面贴合在上滤网15 内壁上，另一个表面呈不光滑磨面。不光滑磨面可以是表面设置有锉齿的磨面，这些锉齿可以磨碎果物。如图1 所示，刀片13 的较长两个侧边可以均是刀刃面，用来切削果物。当然刀片13的四个侧边都是刀刃面也可以，具体根据使用需要设计。刀片13 的较长侧边与上滤网的母线呈一定倾斜角。如图1 所示，上滤网15 呈圆锥筒状，上滤网孔均匀分布在圆锥筒壁上。上滤网15固定在滤网架8上，所述滤网架8 也呈圆锥筒状。滤网架8的圆锥筒壁中部镂空 ，镂空部分设置有若干个间隔的竖向加强筋81。滤网架8的圆锥筒上方连接一个内齿轮12，内齿轮12 与果蔬榨磨机上的齿轮传动机构相连。所述齿轮传动机构通过控制内齿轮12来实现控制滤网架8的转动。
如图2 所示，刀片13 的侧边cb 是刀刃面，且侧边cb 与上滤网15 的母线ab 之间设置有一倾斜角，且所述倾斜角为30-60 度之间的任一角度均可。使用时，侧边与上滤网15 的母线之间的倾斜角最好是设置成50 度左右。
如图7和图8所示，本发明的一种果蔬榨磨机，整机由机头20，磨浆过滤装置和电机底座25三部分组成，上述三部分以插扣旋转方式连接，方便于拆开。电机底座25上方凸设有一电机轴18。
磨浆过滤装置包括滤网机构和螺杆传动机构：所述螺杆传动机构包括螺杆21和中心轴4，中心轴4套接在螺杆21上，螺杆21套接在电机轴18上，故中心轴4和螺杆21可在电机轴18驱动下旋转。螺杆21呈上小下大的纺锥型球体，且球体外表面上设置有呈螺旋线状的凸条16。螺杆21的中心轴与上滤网15和下滤网17套接后的中心轴重合，且螺杆21边缘与上滤网内壁和下滤网内壁之间分别留有间隙，这个间隙就是果物喂料进入后被处理的空间。如图2所示，果物喂料进入后被处理的空间上方设置有一加料口19，所述空间的下方设置有一个排渣口24和一个排汁口36 。
滤网机构包括上滤网机构和下滤网机构。上滤网机构包括上滤网15、滤网架8和设置在上滤网内壁上的刀片13。如图2和图3所示，上滤网15内壁上设置有三个刀片13。这里的刀片可以根据需要来设置个数，并不限定三个。所述三个刀片13中的每一个刀片均呈片状，且刀片13的其中一个表面贴合在上滤网15内壁上，刀片13的另一表面呈不光滑磨面，即另一个表面上设置有锉齿。如图2所示，刀片13的侧边cb是刀刃面，且侧边cb与上滤网15的母线ab之间设置有一倾斜角，且所述倾斜角为30-60度之间为宜。且实际使用时，这个倾斜角设置成50度左右为最佳。上滤网15呈圆锥筒状，滤网孔均匀分布在圆锥筒壁上。滤网架8呈圆锥筒状，且所述圆锥筒壁中部镂空 ，镂空部分设置有若干个间隔的竖向加强筋82；滤网架8圆锥筒上方连接一个内齿轮12，内齿轮12可与机头20内的控制滤网架旋转的离合机构中的齿轮11相连，从而通过内齿轮12与齿轮11的啮合或脱离来控制滤网架的转动或停止。下滤网机构包括下滤网17、中圈网23、遮挡圈23和中圈架2。中圈架2可通过螺纹连接等方式连接在滤网架8的下方，下滤网17连接在中圈网23上。如图5所示，中圈网23上固定有一遮挡圈33，遮挡圈33上设置有若干缺口331，所述缺口331处为中圈网网孔区域，且中圈网网孔孔径分别大于上滤网网孔和下滤网网孔。遮挡圈33上还连接有一中圈架2，中圈架2上对应设置有若干与遮挡圈33上缺口331配合的窗口231。如图4所示，中圈架2旋转套设在遮挡圈33上。且中圈架2上设置有一锁紧螺栓39，对应的遮挡圈33上设置有一滑槽38。锁紧螺栓39可随着中圈架2的转动而在滑槽38内滑动。当锁紧螺栓39滑动到滑槽38一端时，例如滑动到如图5所示的滑槽38左端，即滑动到中圈架2指示条的0端方向时，可以拧紧锁紧螺栓，将中圈架2锁止在该处。
滤网架8上还固定有一个清网片1。清网片1采用类似硅胶等软性材料制成。且所述清网片1一直延伸至中圈架2的下方。中圈架2上还设置有径向凸出的中圈耳22。当滤网架8带着中圈架2一起转动时，上清网片1也会随着转动，当清网片1转动到中圈耳22的位置时，由于清网片1是软性材质，清网片1会弯曲后越过中圈耳22继续随着转动，只是当转动到中圈耳22位置时，会对中圈架2施力。对中圈耳2施力后，中圈架会被旋转至指示条1的位置处。反之，当中圈架2停在指示条1的位置处时，电机设置两个转向按钮使电机逆向转动，然后经传动机构使滤网架转动并经清网片将中圈架从滑道1端转动至滑道0端，从而关闭中圈网，实现了自动换网。
机头20内设置有滤网架8锁止的定位机构和控制滤网架8旋转的传动机构。机头20内的控制滤网架8旋转的传动机构包括套设在中心轴4上的压簧5、离合齿轮6和离合齿轮7、齿轮9、齿轮10和齿轮11。中心轴4在电机轴18和螺杆21的作用下旋转。中心轴4的并列位置处还设置有一滑杆26，滑杆26上设置有一压簧27，压簧27下方设置有一拔叉28。拔叉28的一端固定在滑杆26上，即压簧27的下方，另一端套在离合齿轮6的轮颈上。滑杆26的末端设置有一个滑轮29，滑轮29顶设在凸轮槽30内。
当向左摆动凸轮手柄35，滑轮29随着凸轮30下降，拔叉28也随着滑轮29下降，同时离合齿轮6下降与离合齿轮7咬合。离合齿轮6和离合齿轮7咬合后，齿轮9与齿轮10转动构成二级变速系。再经齿轮11带动内齿轮12转动，使滤网架8转动。滤网架8转动的同时，滤网架上的上滤网15和上滤网15上的刀片均随着转动。且滤网架8和螺杆21是反向运动，使果蔬在滤网机构和螺杆机构中被磨浆。
所述控制滤网架8锁止的定位机构包括锁定轮31、压簧片14、凸轮30和凸轮手柄35。锁定轮31设置在凸轮30的下端，且所述锁定轮31呈月牙形，随着凸轮30的摆动可以嵌入内齿轮12内锁止内齿轮12的转动。压簧片14固定在机身上，且紧靠住锁定轮31的轮廓边，对锁定轮31的锁定起到止动作用。
当凸轮手柄35向右摆动时，凸轮30随之摆动。随着凸轮30的摆动，在拔叉28的作用下，分离了离合齿轮6与离合齿轮7，从而使滤网架转动能够慢慢停止下来。同时，当凸轮手柄35向右摆动时，锁定轮31也随着凸轮30一起运动。由于锁定轮31呈月牙形，随着凸轮30的摆动，锁定轮31可以嵌入内齿轮12的任一内齿中，从而锁止内齿轮12转动，彻底使滤网静止下来。
还包括一清网机构，所述清网机构包括螺杆端面齿轮34，过桥齿轮和清网架3，在清网架3中嵌入下清网片37，下清网片37一侧贴住下滤网17，另一侧贴住过滤座（透明杯）。清网架3套在中圈架2下面作转动。当螺杆21转动时，通过过桥齿轮传动使清网架3在中圈架2下作绕圈运动，转动中的清网片1和下清网片37在括清上下滤网孔中阻塞物同时使较稠的果浆括向排汁管36。
本发明的果蔬榨磨机具有以下几种工作状态：
粗浆工作状态
当向左摆动凸轮手柄35，滑轮29下降，拔叉28也随着滑轮29下降，同时离合齿轮6下降与离合齿轮7咬合。离合齿轮6和离合齿轮7咬合后，齿轮9与齿轮10转动构成二级变速系。再经齿轮11带动内齿轮12转动，使滤网架8转动。滤网架8转动的同时，滤网架上的上滤网15和上滤网15上的刀片均随着转动。且此时滤网架8和螺杆21是反向运动，使果蔬在滤网机构和螺杆机构中被磨浆。
进一步的，清网片1也随着滤网架8转动。由于清网片1延伸至中圈架2下方，当清网片1转动至中圈架的三个中圈耳22的任一个上时，会对中圈架2施力，中圈架2随之旋转。当中圈架转动至指示条1的下方的滑槽一端位置处时，在锁紧螺栓的阻挡下被锁止住，同时，遮挡圈上的窗口21与中圈网的上的粗网孔区域172重合，即粗网孔区域被打开。于是果浆在螺杆21作用下从粗孔网中过滤，由于果蔬经刀片的反复切割的同时果浆在压榨工作前段从粗网孔区域被过滤，凭借这些因素所以从果蔬榨磨机中出来的果浆是粗果浆，故机构处于粗果浆工作状态。例如制作含有较多豆渣的豆浆和青椒苹果等果蔬时可以使用粗果浆状态。
细浆工作状态
当向左摆动凸轮手柄35，滑轮29下降，拔叉28也随着滑轮29下降，同时离合齿轮6下降与离合齿轮7咬合。离合齿轮6和离合齿轮7咬合后，齿轮9与齿轮10转动构成二级变速系。再经齿轮11带动内齿轮12转动，使滤网架8转动。滤网架8转动的同时，滤网架上的上滤网15和上滤网15上的刀片均随着转动。且此时滤网架8和螺杆21是反向运动，使果蔬在滤网机构和螺杆机构中被磨浆。
进一步的，将滤网机构中的中圈架转动至指示条0下方的滑槽一端，并拧紧锁紧螺栓。（目前该机构中采用手动取出滤网机构，并手动转动中圈架，然后拧紧锁紧螺栓，以防止中圈架被滤网架带动）。这样中圈架就挡住了遮挡圈上的中圈网粗网孔区域，即中圈网的粗网孔区域被关闭。这样果浆从下滤网的网孔过滤，由于果蔬经刀片的切割与反复碾磨下在压榨工作段从滤网细孔中被过滤，所以从榨磨机出来的果浆为细浆。故机构处于细果浆状态。例如，制作含有较少豆渣的豆浆和水果时可以使用细浆状态。
果汁工作状态
当凸轮手柄35向右摆动时，离合凸轮30随之摆动。随着离合凸轮30的摆动，在拔叉28的作用下，分离了离合齿轮6与离合齿轮7，从而使滤网架转动能够慢慢停止下来。同时，当凸轮手柄35向右摆动时，锁定凸轮31也随着离合凸轮30一起运动。由于锁定凸轮35呈月牙形，随着离合凸轮30的摆动，锁定凸轮35可以嵌入内齿轮12的任一内齿中，从而锁止内齿轮转动。在滤网架8被锁定后，上滤网15与刀片13均静止。由于刀片静止，所以果蔬没有被很好的切割，只是被刀片的锉齿磨面磨碎，此时在螺杆旋转挤压下，果蔬在螺杆机构与滤网机构中被处理。
进一步的，将滤网机构中的中圈架转动至指示条0下方的滑槽一端，中圈架就挡住了遮挡圈上的中圈网粗网孔区域，即中圈网的粗网孔区域被关闭。这样果浆从下滤网的网孔过滤，由于果蔬未经有效切割与磨浆同时又在压榨段过滤，所以出来的为果汁。中圈架的转动方法可以采用如下方式，电机设置两个转向按钮使电机逆向转动，然后经传动机构使滤网架转动并经清网片将中圈架从滑道1端转动至滑道0端，从而关闭中圈网。例如，制作含有较少渣的黄瓜汁或橙汁时可以使用果汁状态。
果泥工作状态
当凸轮手柄35向右摆动时，离合凸轮30随之摆动。随着离合凸轮30的摆动，在拔叉28的作用下，分离了离合齿轮6与离合齿轮7，从而使滤网架转动能够慢慢停止下来。同时，当凸轮手柄35向右摆动时，锁定凸轮31也随着离合凸轮30一起运动。由于锁定凸轮35呈月牙形，随着离合凸轮30的摆动，锁定凸轮35可以嵌入内齿轮12的任一内齿中，从而锁止内齿轮转动。在滤网架8被锁定后，上滤网15与刀片13均静止。由于刀片静止，所以果蔬没有被很好的切割。此时螺杆旋转挤压果蔬，果蔬在螺杆机构与滤网机构中被处理。
进一步的，将滤网机构中的中圈架转动（可以采用粗浆工作状态时的方法）至指示条1下方的滑槽一端。这样，遮挡圈上的窗口21与中圈网的上的粗网孔区域172重合，即粗网孔区域被打开。于是果浆在螺杆21作用下从粗孔网中过滤，由于果蔬没有经有效的切割与碾磨只有经过刀片平面锉齿磨碎时果浆在压榨前段从粗网孔区域被过滤，所以果蔬榨磨机中出来的果浆是果泥状态，故机构处于果泥工作状态。例如利用番茄、或生或熟的果蔬等可以采用果泥工作状态。
综上所述，本发明的果蔬榨磨机的工作状态可以用下表来简单概括。

打开 是 粗浆
本发明的果蔬榨磨机也可以采用如下方式实施：
如图9和图10 所示，本发明的一种果蔬榨磨机，整机由机头20，磨浆过滤装置22 和电机底座25 三部分组成，上述三部分以插扣旋转方式连接，方便于拆开。电机底座25 上方凸设有一电机轴18。
磨浆过滤装置22 包括滤网机构和螺杆传动机构：所述螺杆传动机构包括螺杆21和中心轴4，中心轴4 套接在螺杆21 上，螺杆21 套接在电机轴18 上，故中心轴4 和螺杆21可在电机轴18 驱动下旋转。螺杆21 呈上小下大的纺锥型球体，且球体外表面上设置有呈螺旋线状的凸条16。螺杆21 的中心轴与上滤网15 和下滤网17 套接后的中心轴重合，且螺杆21 边缘与上滤网内壁和下滤网内壁之间分别留有间隙，这个间隙就是果物喂料进入后被处理的空间。如图2 所示，果物喂料进入后被处理的空间上方设置有一加料口19，所述空间的下方设置有一个排渣口24 和一个排汁口41 。
滤网机构包括上滤网15、滤网架8 和下滤网17。如图3 和图4 所示，上滤网15 内壁上设置有三个刀片13。这里的刀片可以根据需要来设置个数，并不限定三个。即可以根据需要设置成四个或五个，甚至更多个。所述三个刀片13 中的每一个刀片13 均呈片状，且刀片13 的其中一个表面39 贴合在上滤网15 内壁上，刀片13 的另一表面呈不光滑磨面，即另一个表面上设置有锉齿38。如图5 所示，刀片13 的侧边cb 是刀刃面，且侧边cb 与上滤网15 的母线ab 之间设置有一倾斜角，且所述倾斜角为30-60 度之间为宜。且实际使用时，这个倾斜角设置成50 度左右为最佳。上滤网15 呈圆锥筒状，滤网孔均匀分布在圆锥筒壁上。上滤网15 上的滤网孔呈粗网孔区域和细网孔区域间隔分布。如图4 所示，粗网孔区域即图中的A 区域，整个上滤网15 上均匀间隔分布有四个如A 区域所示的粗网孔区域。当然在实际使用中，这个粗网孔区域可根据需要设置，不限于四个。滤网架8 呈圆锥筒状，且所述圆锥筒壁中部镂空 ，镂空部分设置有若干个间隔的竖向加强筋81 ；滤网架8 圆锥筒上方连接一个内齿轮82，内齿轮82 可与机头20 内的控制滤网架旋转的离合机构中的齿轮11 相连，内齿轮82 上的内齿12 可与齿轮11 配合来控制滤网架的转动。滤网架8 圆锥筒上方连接的内齿轮82 上端面上还设置有四个卡槽40。所述卡槽40 可与机头20 内的滤网架锁定机构中的定位销1 配合来控制滤网架的锁止。且滤网架被锁住时，粗网孔区域刚好被机身
上对应位置的海绵或橡胶类阻挡件封住，即此时只有细网孔处可以出汁，达到了自动换网的目的。而且这里的卡槽40 个数可根据滤网的粗网孔区域的个数来定，并不限定四个。
机头20 内设置有机头锁住机构、滤网架锁定机构和控制滤网架旋转的传动机构。机头20 内的控制滤网架旋转的传动机构包括套设在中心轴4 上的压簧5、离合齿轮6 和离合齿轮7、齿轮9、齿轮10 和齿轮11。中心轴4 在电机轴18 和螺杆21 的作用下旋转。中心轴4 的并列位置处还设置有一滑杆26，滑杆26 上设置有一压簧27，压簧27 下方设置有一拔叉28。拔叉28 的一端固定在滑杆26 上，即压簧27 的下方，另一端套在离合齿轮6 的轮颈上。滑杆26 的末端设置有一个滑轮29，滑轮29 顶设在凸轮槽30。当向下摆动凸轮手柄35，滑轮29 下降，拔叉28 也随着滑轮29 下降，同时离合齿轮6 下降与离合齿轮7 咬合。离合齿轮6 和离合齿轮7 咬合后，齿轮9 与齿轮10 转动构成二级变速系。再经齿轮11 带动内齿轮12 转动，使滤网架8 转动。此时，滤网架8 和螺杆21 反向运动，使果蔬在滤网架8 和螺杆21 的反向旋转中被磨浆，故机构则处于磨浆工作状态。
机头20 内的滤网架锁定机构包括定位销1、压簧2 和连杆3。连杆3 通过一转轴固定在机身上，且连杆3 可绕转轴转动。连杆3 的一端套设在换网滑轮33 上，另一端套设在定位销1 上。定位销1 上套设有一压簧2，压簧2 的一端被机壳压住，另一端被套设在定位销1 上的连杆3 压住。当换网滑轮33 沿凸轮槽31 转动时，即可控制连杆3 的摆动。定位销1 的一端套住机架，另一端可在压簧2 的作用下嵌入内齿轮82 上端面的卡槽40 中。当凸轮槽31 作用到换网滑轮33 上时，连杆3 摆动抬起定动销1，使定位销1 从卡槽40 中跳出，同时使内齿轮82 与定动销1 分离，解除了对滤网架8 和上滤网15 的锁定，使机构处于磨浆工作状态。反之，当定位销1 被压下后嵌入卡槽40 内，此时则锁住了滤网架8 和上滤
网15，且锁止时，上滤网15 上的粗网孔区域被机架上相应位置的封口海绵或橡胶类封闭件14 封住，即粗网孔区域被封闭了。使果浆只能从细网孔中过滤，达到自动换网的目的。且滤网架8 被锁止后，上滤网15 和刀片13 均静止。使果蔬在螺杆21 旋转中与刀片13 切割粉碎，故机构则处于榨汁工作状态。
所述机头锁住机构包括锁盖凸轮32、凸轮控制手柄35 和锁盖杆34，凸轮控制手柄35 用于控制锁盖凸轮32 的转动，锁盖凸轮32 转动的同时控制锁盖杆34 的移动，当锁盖杆34 移动到机架的锁槽38 内时，机头则被锁住。反之，当锁盖杆34 移动到机架的锁槽38 外时，则可以将机头拿出。上述凸轮控制手柄35 在实际使用中也可以设置成推键形式。
