为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
下面将详细描述本发明的各个方面的特征和示例性实施例。在下面的详细描述中,提出了许多具体细节,以便提供对本发明的全面理解。但是,对于本领域技术人员来说很明显的是,本发明可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本发明的示例来提供对本发明的更好的理解。本发明决不限于下面所提出的任何具体结构和配置,而是在不脱离本发明的精神的前提下覆盖了零件、部件和连接方式的任何修改、替换和改进。
此外,所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施例中。在下面的描述中,提供许多具体细节从而给出对本发明的实施例的充分理解。
需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。相同的附图标记在不同的图中可能代表不同的元件。
本发明实施例提供的榨汁机刀具,可用于在果实内部对果肉进行刮削以制取果汁,包括旋转件、弹性刀片和径向外展机构。
径向外展机构包括多个构件,多个构件之间为转动或可移动的连接关系,多个构件中的部分构件可动地连接在旋转件上。多个构件中的部分构件之间发生相对运动时其之间的相对位置关系会发生变化,在合理的配置 中,使其中一个构件相对于其他构件动作时,多个构件能够部分或全部地收拢至旋转件内/旋转件周围,或者沿旋转件的径向展开。
旋转件具有预定长度;弹性刀片沿旋转件长度方向配置;径向外展机构设置于旋转件与弹性刀片之间并连接旋转件和弹性刀片,径向外展机构能驱动弹性刀片沿旋转件的径向远离和靠近旋转件。径向外展机构收拢于旋转件时,弹性刀片也可以贴紧/贴近旋转件,从而使榨汁机刀具具有较小的径向尺寸,以便以插入果实内部。将榨汁机刀具插入果实内部后,可以驱动旋转件绕其自身旋转轴转动,同时带动径向外展机构和弹性刀片产生回转运动。在榨汁机刀具旋转的同时,可以驱动径向外展机构动作,以使弹性刀片逐渐远离旋转件,即实现弹性刀片从果实中心向果皮对果肉进行刮削。在上述过程中,弹性刀片的两端会受到果肉和/或果皮的阻力而弯曲,使得弹性刀片具有一定弧度,能够与果皮的内表面贴合,实现对果肉的充分刮削。
图1至图3示出了本发明一个实施例提供的榨汁机刀具100。图1为根据本发明一个实施例提供的榨汁机刀具的轴测图,图2为图1中所示榨汁机刀具展开后的主视图,图3为图2中的局部放大视图I。
榨汁机刀具100包括旋转件110、滑杆120、第一摇臂130、第二摇臂140、第一连杆150、第二连杆160和两个弹性刀片190。滑杆120能够沿旋转件110滑动,第一摇臂130铰接于旋转件110,第一连杆150连接滑杆120和第一摇臂130,使滑杆120、第一摇臂130和第一连杆150形成摇臂滑块机构,即一组径向外展机构。滑杆120、第二摇臂140和第二连杆160形成另一组摇臂滑块机构,即另一组径向外展机构。一个弹性刀片190沿旋转件110的长度方向配置,一端连接于旋转件110的底部一端,并且,弹性刀片190的垂直于其厚度方向上的一个面面向旋转件110。另外一个弹性刀片190以同样的方式连接于旋转件110上,并与前述一个弹性刀片190关于旋转件110对称。本实施例中弹性刀片190与旋转件110之间为铰接连接,铰轴平行于弹性刀片190的宽度方向。
旋转件110为转轴,转轴的一部分轴体上设置有沿长度方向的长槽111,且长槽111从径向贯穿转轴。转轴的一端设置有轴向的中心孔,该 中心孔与长槽111连通;转轴的另一端还设置有径向的销孔,销孔的方向平行于于长槽111的宽度方向,即销孔为径向孔。
滑杆120为圆柱杆,一端设置有径向贯通的销孔。滑杆120设置在旋转件110的中心孔内,滑杆120上设置有销孔的一端可以延伸至旋转件110的长槽111内,另一端可伸出旋转件110的中心孔之外。滑杆120可以在旋转件110的中心孔内往复滑动。
第一摇臂130为杆状结构。第一摇臂130的两端和中部均设置有销孔,且三个销孔的轴线平行。130的一端设置于旋转件110的长槽内,且该端的销孔与旋转件110上的销孔同轴设置,并通过销轴贯穿连接形成铰接连接。第一摇臂130可以在旋转件110上转动,转动时其另一端可以在旋转件110的一侧远离或靠近旋转件110。本实施例中,第一摇臂130的自由端还设置有可转动的滚轮199,滚轮199的轴线与第一摇臂130的销孔轴线平行。在可选实施例中,滚轮199的圆周面的边缘(滚轮端面边缘)还设置有凸缘,凸缘之间的距离可以大于等于弹性刀片190的宽度。
第一连杆150为杆状结构,其两端设置有用于铰接的销孔,两个销孔平行。第一连杆150的一端与滑杆120的一端形成铰接连接,第一连杆150的另一端铰接于第一摇臂130中部的销孔。滑杆120、第一摇臂130和第一连杆150形成摇臂滑块机构,滑杆120在旋转件110上往复滑动时可驱动第一摇臂130在旋转件110上的绕铰接处摆动,第一摇臂130和第一连杆150可以收拢至旋转件110的长槽内。
弹性刀片190为长条状刀片,可沿其厚度方向发生弹性弯曲,其宽度方向上的边缘可刮削果肉。弹性刀片190的末端部分的背向旋转件110的一侧为弧面191。
其中一个弹性刀片190的一端铰接于旋转件110的底端,且与第一摇臂130在同一平面上,即,第一摇臂130在旋转件110上转动时其另一端的滚轮199的圆周面能够抵靠接触弹性刀片190的面向旋转件110的一个面,推动弹性刀片190的未与旋转件110连接的部分沿旋转件110的径向远离旋转件110。
第二摇臂140的结构与第一摇臂130的结构相同,一端铰接于旋转件 110末端的销孔上,且与第一摇臂130关于旋转件110对称。第二摇臂140的自由端也设置有滚轮199。
第二连杆160与第一连杆150的结构相同。第二连杆160的两端分别铰接于第二摇臂140中部的销孔和滑杆120末端的销孔。第二连杆160和第一连杆150关于旋转件110对称。
另一个弹性刀片190的一端铰接于旋转件110的底端,且与第二摇臂140在同一平面上,即,第二摇臂140在旋转件110上转动时其另一端的滚轮199的圆周面能够抵靠接触弹性刀片190的面向旋转件110的一个面,推动弹性刀片190的未与旋转件110连接的部分沿旋转件110的径向远离旋转件110。
使用时,先使滑杆120朝向旋转件110的中心孔的外部滑动,此时第一连杆150和第二连杆160分别驱动第一摇臂130和第二摇臂140同时靠近旋转件110,最终使第一摇臂130、第二摇臂140、第一连杆150、第二连杆160收拢至旋转件110的长槽111内,并转动两个弹性刀片190,使二者也位于长槽111内部或贴紧/贴近旋转件110。此时榨汁机刀具100具有较小的径向尺寸,可以将榨汁机刀具100整体插入诸如橙子的果实的内部,并使橙子或榨汁机刀具100转动,从而使弹性刀片190与果实之间产生相对转动。在进行上述转动动作的同时,驱动滑杆120插入旋转件110上的中心孔内,使弹性刀片190在绕果实中心线旋转的过程中逐渐由第一摇臂130和第二摇臂140推动远离旋转件110,弹性刀片190的自由端在果肉和/或果皮的作用下弯曲为弧形,实现对果肉的层层刮削,直至弹性刀片190贴紧橙皮的内表面,将果实内部的果肉刮削形成果汁。
第一摇臂130和第二摇臂140收拢至长槽111内的过程中,弹性刀片190可以因弹性而由弧形逐渐向原来的直线形状恢复。
弹性刀片190的未与旋转件110铰接的一端为自由端,因此其向橙皮靠近的过程中会受到来自果肉和果皮的压力,使弹性刀片190整体弯曲为弧形,即能够形成与果实果皮内表面贴合的弧度,对果肉的刮削更充分。
弹性刀片190的末端部分的背向旋转件110的一侧为弧面191。使用时,弹性刀片190的末端的背向旋转件110的一侧与果肉或果皮之间具有 较大的压力,当将该部分设置为弧面时可使该端无尖角,从而减轻刀片对果皮的破坏。
在一些可选实施例中,弹性刀片190的末端部分的垂直于宽度方向且背向旋转件110的侧面为弧面。在一些可选实施例中,弹性刀片190的末端具有圆滑的曲面表面,即弹性刀片190的末端为圆头,能够进一步减轻对果皮的刮削。当然,其他除去弹性刀片190末端尖角的结构也可以减轻对果皮的刮削,如倒角或倒圆角结构。
第一摇臂130、第二摇臂140、第一连杆150和第二连杆160位于弹性刀片190面向旋转件110的一侧,因此不会与未受刮削的果肉部分接触,不会对榨汁机刀具100或果实的转动产生较大阻力。固定果实或驱动果实转动时,均需要对果实进行夹持,以使夹持物(或操作者的手)与果皮表面产生足够的静摩擦力。当榨汁机刀具100与果实内部的阻力较小时,对夹持物(或操作者的手)与果皮表面之间的静摩擦力的需求也会减小,从而无需对果实表面施加太大的压力,避免果实变形,防止果汁溢出或果皮表面凹陷时被弹性刀片190刮削破坏。
弹性刀片190与旋转件110之间为铰接连接,第一摇臂130或第二摇臂140推动弹性刀片190远离旋转件110时,弹性刀片190铰接的一端可以自由转动,因此不会阻碍弹性刀片190的形变。在可选实施例中,弹性刀片190与旋转件110之间还可以为固定连接。
上述实施例中,弹性刀片190的一端连接于旋转件110上,另一端呈完全自由的状态。在一些可选实施例中,弹性刀片190的另一端还可以被设置成可沿旋转件110的轴向滑动。具体地,可以在旋转件110上对应弹性刀片190自由端的位置设置具有用于使弹性刀片190穿过的孔/槽的导向结构(例如环),孔/槽的开口方向沿旋转件110的轴向,弹性刀片190的自由端可以穿过导向结构的孔/槽并在其中滑动。孔/槽的开口还可以设置为喇叭口状,以减轻对弹性刀片190向外扩张的阻碍。在另一些可选实施例中,导向结构还可以被设置为可在旋转件110上转动,转动的轴线方向可以沿着旋转件110的径向或平行于旋转件110的径向,可以使导向结构的孔/槽的开口方向变化,以适应弹性刀片190的形变。
参考图4,图4为根据本发明一个可选实施例提供的弹性刀片的截面示意图。表面192a为弹性刀片面向旋转件110的一侧,表面193a为弹性刀片背向旋转件110的一侧,侧面194a为面对弹性刀片宽度方向上的一个侧面。侧面194a与表面193a之间为锐角,二者为刀刃的两个面。在本可选实施例中,表面193a上设置有凸出于其表面的筋条195a,筋条195a的延伸方向与弹性刀片190的长度方向一致。筋条195a具有呈柱面或锥面状的表面,即,筋条的横截面中,其表面为弧形。筋条195a能降低弹性刀片的表面193a与果实果皮内表面的压紧程度,从而防止弹性刀片190的刃口过多切入至果皮内,减轻对果皮的刮削;另外,筋条195a具有圆滑的表面,因此不会显著增大榨汁机刀具的旋转阻力;同时,筋条195a的圆滑表面还可以对附着于果实果皮内表面的果肉进行挤压榨取果汁;除此之外,筋条195a还能增大刀片的抗扭刚度,防止弹性刀片发生扭转变形。
参考图5,图5为根据本发明另一个可选实施例中的弹性刀片的截面示意图;;在本可选实施例中,表面192b为面向旋转件110的一侧,表面193b为背向旋转件110的一侧,侧面194b为面对弹性刀片宽度方向的一个侧面。侧面194b与表面193b之间为锐角,即,二者为刀刃的两个面。表面193b整体为弧面,即,在弹性刀片190的横截面上,其背向旋转件110的一侧的表面形状为弧形,能防止弹性刀片190的刃口对果皮的过度刮削,同时能增大刀片的抗扭刚度,防止发生扭转变形。
参考图6,图6为根据本发明一个可选实施例中的弹性刀片的结构示意图,视图方向为沿弹性刀片190厚度方向。在本可选实施例中,弹性刀片190用于与摇臂连接的部分的宽度大于其两端部分的宽度,由中间向两端递减。上述设置可以减轻弹性刀片两端对中部的扭矩,相当于增大弹性刀片的抗扭刚度,能减小弹性刀片发生扭转的可能性。
参考图7和图8,图7为根据本发明另一个实施例提供的榨汁机刀具200的结构示意图,图8为图7中挡块的结构示意图。图7中的双点划线 线圈用于示意果实的果皮轮廓。榨汁机刀具200包括旋转件210、滑杆220、第一摇臂230、第二摇臂240、第一连杆250、第二连杆260和两个弹性刀片290。
本实施例中的榨汁机刀具200具有与榨汁机刀具100基本相同的结构,不同之处在于:榨汁机刀具200还包括挡块10:弹性刀片290的长度大于弹性刀片190,弹性刀片290的一端固定于旋转件210的底端:第一摇臂230和第二摇臂240的自由端不设置有滚轮。
挡块10包括环体11、限位部12和限位部13。本实施例中限位部12和限位部13为圆柱状结构,且关于环体11的中心呈中心对称关系。环体11具有中心孔,限位部12和限位部13从环体11的径向凸出。
挡块10通过其中心孔安装在旋转件210的一端(中心孔开口的一端),挡块10能够沿旋转件210的轴向滑动。当挡块10安装在旋转件210上时,限位部12位于一个弹性刀片290的背向旋转件210的一侧,弹性刀片290的一端的背向旋转件210的一面抵靠在限位部12上。限位部13位于另一个弹性刀片290的背向旋转件210的一侧,该弹性刀片290的一端的背向旋转件210的一面抵靠在限位部13上。
当弹性刀片290由第一摇臂230和第二摇臂240的自由端驱动远离旋转件210时,限位部12和限位部13能够分别对两个弹性刀片290的一端进行限位,但不会限制其表面相对于限位部12的滑动,从而使弹性刀片290的端部朝向果实中心发生弯曲,可以避免弹性刀片290对果实插入口处的果皮部的过度刮削。并且,弹性刀片290发生弯曲后的曲率中心在弹性刀片290的面向旋转件210的一侧,其弯曲后的弧形更接近果实果皮的形状,对果实果肉的刮削更充分。
参考图9和图10,图9为根据本发明另一个实施例提供的榨汁机刀具的结构示意图,图10为图9中挡块的结构示意图。
本实施例中的榨汁机刀具600具有与榨汁机刀具100基本相同的结构,不同之处在于,榨汁机刀具600还包括挡块20。
挡块20包括环体181b、两个孔23和两个限位部22。环体181b为盘 状环结构,盘中心设置有中心孔,盘体上设置有两个在厚度方向上贯通的孔23。孔23的一个侧壁形成限位部22。两个限位部22关于挡块20的中心孔的中心呈中心对称关系。
挡块20的中心孔套装于滑杆620上,能在滑杆620上轴向滑动。在可选实施例中,挡块20还可以套装于旋转件610上。一个弹性刀片690的一个端部穿过挡块20上的一个孔23,另一个弹性刀片690的一个端部穿过挡块20上的另一个孔23。当弹性刀片690远离旋转件610时,挡块20的限位部22会限制弹性刀片690远离旋转件610,但不会限制其表面相对于限位部22的滑动,从而使弹性刀片690发生弯曲。上述设置可以减轻弹性刀片690对果实上刀具插入口处果皮的过度刮削。
参考图11和图12,图11为根据本发明一个可选实施例提供的榨汁机刀具300的弹性刀片390和第一摇臂330的连接结构示意图,图12为图11中第一摇臂330的自由端的结构示意图。
本实施例中榨汁机刀具与前述实施例的区别在于摇臂与弹性刀片之间连接方式,因此下文仅对弹性刀片390和第一摇臂330的相关结构进行说明,榨汁机刀具300的其他结构不在此赘述。
第一摇臂330的自由端(用于推动弹性刀片的一端)的端面上设置有凸出部,凸出部位于该端面的中部(弹性刀片宽度方向上的中部)。凸出部上与该自由端的端面邻接的两个侧面为第二限位面333和第二限位面334。该自由端的与第二限位面333邻接的部分为第一限位面331,与第二限位面334邻接的部分为第一限位面332。
弹性刀片390上设置有沿其长度方向的槽391。本实施例中槽391为通透的槽,即从弹性刀片390的厚度方向上贯通,在可选实施例中该槽还可以为不通透的槽。
使用时,第一摇臂330自由端的凸出部可以插入弹性刀片390上的槽391内。第一限位面331和第一限位面332可以抵靠接触弹性刀片390的面对旋转件的一个面,第二限位面333和第二限位面334能够抵靠接触槽391的两个侧壁。
摇臂自由端的端面还可以为斜面、弧面或其他形状,只要能够对弹性刀片产生抵靠推动作用即可。
参考图13和图14,图13为根据本发明一个可选实施例提供的榨汁机刀具400的弹性刀片490和第一摇臂430的连接结构示意图,图14为图13中第一摇臂430的自由端的结构示意图。榨汁机刀具400与榨汁机刀具300的区别仅在于第一摇臂430的自由端结构不同,下文将做进一步说明,榨汁机刀具400的其他结构不在此赘述。
第一摇臂430的自由端的端面设置有沿摇臂长度方向凸起的凸出部,凸出部的两个侧面(法向方向沿弹性刀片宽度方向的侧面)为第二限位面433和第二限位面434。第二限位面433和第二限位面434上分别设置有沿弹性刀片宽度方向的凸起,两个凸起上面对弹性刀片430自由端的端面的部分为第三限位面435和第三限位面436。弹性刀片430自由端的端面由凸出部分隔为第一限位面431和第一限位面432。

榨汁机刀具500与榨汁机刀具300的区别在于第一摇臂430的自由端结构不同及弹性刀片590上不设置有槽,下文将做进一步说明,榨汁机刀具500的其他结构不在此赘述。
第一摇臂530的自由端的端面设置有沿摇臂长度方向凸起的凸出部,凸出部偏置在端面的一侧,凸出部具有一个与第一摇臂530端面邻接的一 个侧面(法向方向沿弹性刀片宽度方向的侧面),该侧面为第二限位面533。第二限位面533上设置有沿弹性刀片宽度方向的凸起,凸起上面对弹性刀片530自由端的端面的部分为第三限位面535。弹性刀片530自由端的端面与第二限位面533邻接的部分为第一限位面531。

参考图17和图18,图17为根据本发明一个可选实施例提供的榨汁机刀具400d的结构示意图,图18为图17中的局部放大视图II。
榨汁机刀具400d包括旋转件410d、滑杆420d、第一摇臂430d、第二摇臂440d、第一连杆450d、第二连杆460d、两个杆组470d、两个弹性刀片490d和两个导向结构40d。
榨汁机刀具400d与榨汁机刀具100之间的区别在于二者的径向外展机构不同。
榨汁机刀具400d中,径向外展机构包括滑杆420d、第一摇臂430d、第二摇臂440d、第一连杆450d、第二连杆460d和两个杆组470d。第一摇臂430d和第二摇臂440d的中部铰接,且均铰接于旋转件410d。第一摇臂430d和第二摇臂440d结构相同,二者铰接形成“X”形结构。两个杆组杆组470d分别连接于“X”形结构的两侧,形成关于旋转件410d对称的结构。

第一连杆450d的一端铰接于滑杆420d,另一端与第一摇臂430d的销孔434d铰接。滑杆420d、第一摇臂430d和第一连杆450d形成摇臂滑块机构。
第二摇臂440d与第一摇臂430d具有相同的结构,包括第一杆段441d、第二杆段442d、销孔443d、销孔444d和位于两端的另外两个个销孔。第二摇臂440d通过销孔443d铰接于旋转件410d,通过销孔444d与第二连杆460d的一端铰接。第一杆段441d与第二杆段432d位于旋转件410d的同一侧,第二杆段442d与第一杆段431d位于旋转件410d的同一侧。

杆组470d包括两个长度相等的杆件。两个杆件各自的一端同轴铰接形成铰接结构480d,两个杆件的自由端均设置有销孔,且销孔均与铰接结构480d的铰轴平行。一个杆组470d铰接于第一杆段441d和第二杆段432d上,形成平行四杆机构;且该杆组的铰接结构480d连接有弹性刀片490d。另外一个弹性刀片490d通过另外一个杆组470d连接在第二杆段442d和第一杆段431d上。连杆450d和连杆460d分布在滑杆420d的两侧,能够使滑杆420d的受力平衡,减小与旋转件410d上的中心孔之间的摩擦力。
导向结构40d上设置有通透的导向孔41d。两个导向结构40d分别铰接在旋转件410d的两侧,铰轴与弹性刀片490d的宽度方向平行,分别用于对两个弹性刀片490d进行导向。弹性刀片490d的自由端穿过与之对应的导向结构40d上的导向孔41d。弹性刀片490d弯曲时导向结构40d可以随之转动。
参考图19和图20,图19为根据本发明一个可选实施例提供的榨汁机刀具100c的结构示意图,图20为图19中榨汁机刀具100c隐去了旋转件140c后的结构示意图。榨汁机刀具100c与榨汁机刀具100之间的区别在 于二者的径向外展机构不同。
榨汁机刀具包括旋转件140c、弹性刀片170c、径向外展机构和挡块10。径向外展机构包括丝杆110c、第一螺母120c、第二螺母130c、旋转件140c、第一摇臂150c和第二摇臂160c。径向外展机构用于将弹性刀片170c连接至旋转件140c上,径向外展机构动作时能够驱动弹性刀片170c在旋转件140c的径向方向上远离或靠近旋转件140c。
丝杆110c包括顺序连接的枢轴段113c、第一螺纹段111c和第二螺纹段112c。第一螺纹段111c左旋,用于旋合第一螺母120c。第二螺纹段112c右旋,用于旋合第二螺母130c。枢轴段113c用于与旋转件140c配合,形成可转动的轴孔配合。
第二螺母130c的外形大致为圆柱状,具有外圆周面、螺纹孔、铰接部和导向部。螺纹孔的螺纹旋向为右旋。铰接部上设置有用于实现铰接的孔,孔的轴线方向垂直于第二螺母130c的螺纹孔轴线,并且二者的轴线不相交,即形成空间垂直关系。导向部为从径向凸出于第二螺母130c表面的凸台,该凸台具有与第二螺母130c轴线方向平行的侧面(垂直于螺母端面)。
本实施例中,第一螺母120c具有与第二螺母130c基本相同的结构,区别在于二者的螺纹旋向相反,即第一螺母120c的螺纹为左旋螺纹。
第一螺母120c旋合于丝杆110c的第一螺纹段111c,第二螺母130c旋合于丝杆110c的第二螺纹段112c。
第二摇臂160c为杆状,两端均设置有孔,且两个孔的轴线平行。第一摇臂150c的结构同第二摇臂160c的结构相同,第二摇臂160c与第一摇臂150c具有相同的长度。
第二摇臂160c的一端铰接于第二螺母130c,第一摇臂150c的一端铰接于第一螺母120c。同时,第二摇臂160c的另一端和第一摇臂150c的另一端通过销轴形成铰接连接。
当丝杆110c与第一螺母120c和第二螺母130c之间发生相对转动时,第二螺母130c和第一螺母120c之间相互靠近或远离,从而驱动第二摇臂160c和第一摇臂150c之间的夹角变小或变大,同时,第一摇臂150c与第二摇臂160c之间铰接的一端能够远离或靠近丝杆110c。
旋转件140c为筒状结构,一端敞开,另一端设置有直径小于筒内径的轴孔,该轴孔与该筒状结构同轴,其直径与丝杆110c的枢轴段113c的直径相等。旋转件140c的筒壁上设置有平行于其轴向的滑槽。旋转件140c的筒内径大于第二螺母130c的直径。
丝杆110c的枢轴段113c插装于旋转件140c的轴孔,且可在该轴孔中旋转。丝杆110c的第一螺纹段111c、第二螺纹段112c及第一螺母120c和第二螺母130c均位于旋转件140c的筒内,且第二螺母130c的导向部133c和第一螺母120c的导向部位于旋转件140c的滑槽内。
当丝杆110c通过枢轴段113c与旋转件140c之间发生相对转动时,滑槽141c的侧壁能够作用于第二螺母130c的导向部第一螺母120c的导向部,对第一螺母120c和第二螺母130c产生转矩,从而驱动第一螺母120c和第二螺母130c相对于丝杆110c转动,使第一摇臂150c和第二摇臂160c之间的角度变大或变小。
弹性刀片170c为长条形刀片,其厚度小于宽度,当刀片受到厚度方向的力时可以发生弹性变形。弹性刀片170c的一端铰接于旋转件140c的底端。
挡块10包括环体和限位部12,本实施例中限位部12为圆柱状结构。环体具有中心孔,限位部12从环体的径向凸出。
挡块10通过其中心孔安装在旋转件140c的一端,挡块10能够沿旋转件140c的轴向滑动。挡块10安装在旋转件140c上,限位部12位于弹性刀片170c的背向旋转件140c的一侧,弹性刀片170c该端背向旋转件140c的一面抵靠在限位部12上。当弹性刀片170c远离旋转件140c时,限位部12能够对弹性刀片170c的一端进行限位,但不会限制其表面相对于限位部12的滑动,从而使弹性刀片170c的端部朝向果实中心发生弯曲,可以避免弹性刀片170c对果实插入口处的果皮部的过度刮削。并且,弹性刀片170c发生弯曲后的曲率中心在弹性刀片170c的面向旋转件140c的一侧,其弯曲后的弧形更接近果实果皮的形状,对果实果肉的刮削更充分。
使用时,先使第一螺母120c和第二螺母130c之间具有较大的距离,第一摇臂150c与第二摇臂160c之间具有较大的角度,以推动弹性刀片 170c贴近旋转件140c,从而使整个榨汁机刀具具有较小的径向尺寸。再将榨汁机刀具插入至例如橙子的果实中,转动旋转件140c,从而使弹性刀片170c在果实内产生回转运动,对果肉进行刮削。在保持旋转件140c转动的状态下,使丝杆110c相对于旋转件140c转动,以使第一螺母120c和第二螺母130c之间的距离变小,第二摇臂160c和第一摇臂150c之间的夹角逐渐变小,从而驱动弹性刀片170c在丝杆110c的径向方向上远离旋转件140c,进一步对果肉进行刮削。在弹性刀片170c远离旋转件140c的过程中,弹性刀片170c的两端会受到果肉和/或果皮内壁的阻力,使得弹性刀片170c弯曲呈弧形。当弹性刀片170c的中部触及果皮内壁时,弹性刀片170c整体的弧形能够与果皮内壁的弧形贴合,从而完成对整个果实内部果肉的刮削。
参考图21,图21为根据本发明一个实施例提供的榨汁机的结构示意图。
榨汁机30包括榨汁机本体31、驱动电机32、主动齿轮33、从动齿轮34、滑杆驱动装置35和榨汁机刀具100a。
榨汁机刀具100a与榨汁机刀具100具有基本相同的结构,不同之处在于:滑杆120a的一端设置有外螺纹,该端由旋转件110的中心孔伸出。
本实施例中滑杆驱动装置35为设置有螺纹孔的构件,该构件固定于榨汁机本体31,其螺纹孔与榨汁机刀具100a中的滑杆120a同轴,且与滑杆120a的外螺纹形成螺纹传动配合。
榨汁机本体31为各个零部件的安装基体,其具体结构可根据实际需要具体设置,图21中的形状结构仅为示意。
驱动电机32固定于榨汁机本体31上,驱动电机32的输出轴连接有主动齿轮33。
从动齿轮34固定于旋转件110上,且从动齿轮34的转动轴线与旋转件110的转动轴线重合。从动齿轮34与主动齿轮33之间为啮合传动。
榨汁机刀具100a可转动地连接在榨汁机本体31上,具体地,通过旋转件110枢接于榨汁机本体31的孔中。
驱动电机32可以通过主动齿轮33和从动齿轮34驱动榨汁机刀具100a转动。
当旋转件110被驱动转动时,滑杆120a随动,并与滑杆驱动装置35上的螺纹孔之间发生相对转动,滑杆120a会沿其轴向滑动,从而驱动弹性刀片190远离或靠近旋转件110。
在可选实施例中,滑杆驱动装置还可以为其他手动、电动或气动的驱动装置,只要能驱动滑杆沿轴向往复移动即可。
榨汁机30可以作为手持工具使用。操作者可以一手持榨汁机30操作,另一手握紧诸如橙子的果实,将榨汁机刀具100a插入果实后启动,完成榨汁后将100a拔出即可。
本发明实施例还提供了一种榨汁机,包括榨汁机本体、榨汁机刀具、夹持机构、旋转驱动和滑杆驱动装置。榨汁机刀具可以为前述实施例中任意一种榨汁机刀具,榨汁机刀具设置在榨汁机本体上;夹持机构设置于榨汁机本体上,用于夹持待榨汁果实;夹持机构和榨汁机刀具中的至少一者能够自转,从而使二者之间产生相对转动;旋转驱动能够驱动榨汁机刀具或夹持机构自转;滑杆驱动装置能够向滑杆提供动力从而控制滑杆沿轴向滑动。
榨汁机本体包括用于连接榨汁机刀具的部分和用于连接夹持机构的部分。用于连接榨汁机刀具的部分可相对于用于连接夹持机构的部分移动。如本实施例中,用于连接榨汁机刀具的部分设置在用于连接夹持机构的部分的上方,用于连接榨汁机刀具的部分可在上下方向上远离和靠近用于连接夹持机构的部分。
榨汁机刀具可以为前述实施例中任意一种榨汁机刀具,榨汁机刀具可转动地设置在榨汁机本体上,其自转的轴线与滑杆的轴线同轴。
夹持机构固定于榨汁机本体上,用于夹持待榨汁果实。夹持机构可包括两个以上的卡爪,卡爪分布在一个圆周上,从而能够形成对果实的包围和夹持。卡爪所在的圆周的圆心与榨汁机刀具的滑杆轴线重合。卡爪用于夹持果实的面可以设置为弧面,弧面上可以设置例如呈尖角状的凸起。卡 爪夹持果实时,凸起可以插入果实表皮,防止果实转动。设置凸起的好处是,不必完全依靠卡爪与果实表面之间的静摩擦力来防止果实转动,从而减轻卡爪对果实的压力,避免果皮凹陷。
旋转驱动为电动机和传动组件,能够驱动榨汁机刀具的旋转件转动。本实施例中传动组件为齿轮传动,在一些可选实施例中,传动组件还可以为带传动。
滑杆驱动装置,能够向滑杆提供动力从而控制滑杆沿轴向滑动。本实施例中滑杆驱动装置为杠杆机构,可由人工操作,用于向滑杆提供沿滑杆轴向的压力或拉力。在一些可选实施例中,滑杆驱动装置为螺母丝杠副,丝杠与榨汁机刀具中的滑杆同轴连接,螺母固定于榨汁机本体上。具体结构可参考实施例中关于榨汁机30的说明,此处不再赘述。
使用时,通过夹持机构夹持待榨汁的果实。将榨汁机本体上用于连接榨汁机刀具的部分向夹持机构移动,以使榨汁机刀具插入到果实内部。启动旋转驱动,使榨汁机刀具的旋转件带动弹性刀片转动。同时对杠杆机构施压,使滑杆沿旋转件的轴向滑动。弹性刀片在果实内回转的同时逐渐靠近果实果皮的内壁,将果实的果瓤刮削为果汁。
在另一些实施例中,夹持机构作为一个整体可转动地连接在榨汁机本体上。例如,夹持机构包括底座和三个卡爪,底座与榨汁机本体之间为可转动连接;三个卡爪铰接在底座上,并通过在铰接处设置扭簧使得卡爪能够自动夹紧。榨汁机刀具通过旋转件固定在榨汁机本体上。旋转驱动用于驱动夹持装置转动。
图22为根据本发明一个实施例提供的榨汁机刀具100的轴测图,图23为图22中所示榨汁机刀具100的工作原理示意图,图24为图22中第二螺母130的结构示意图,图25为图23中的局部放大视图I。其中,图23中的双点划线线圈a用于示意果实的果皮内壁轮廓,且图23中的榨汁机刀具100是隐去了旋转件140后的结构示意图。
本实施例中,榨汁机刀具包括旋转件140、弹性刀片170和径向外展机构。径向外展机构包括丝杆110、第一螺母120、第二螺母130、第一摇臂150和第二摇臂160。径向外展机构用于将弹性刀片170连接至旋转件 140上,径向外展机构动作时能够驱动弹性刀片170在旋转件140的径向方向上远离或靠近旋转件140。
参考图23,丝杆110包括顺序连接的枢轴段113、第一螺纹段111和第二螺纹段112。第一螺纹段111左旋,用于旋合第一螺母120。第二螺纹段112右旋,用于旋合第二螺母130。枢轴段113用于与旋转件140配合,形成可转动的轴孔配合。
参考图24,第二螺母130的外形大致为圆柱状,具有外圆周面、螺纹孔131、铰接部132和导向部133。螺纹孔131的螺纹旋向为右旋。铰接部132上设置有用于实现铰接的孔,孔的轴线方向垂直于第二螺母130的螺纹孔轴线,并且二者的轴线不相交,即形成空间垂直关系。导向部133为从径向凸出于第二螺母130表面的凸台,该凸台具有与第二螺母130轴线方向平行的侧面。
本实施例中,第一螺母120具有与第二螺母130基本相同的结构,区别在于二者的螺纹旋向相反,即第一螺母120的螺纹为左旋螺纹。
第一螺母120旋合于丝杆110的第一螺纹段111,第二螺母130旋合于丝杆110的第二螺纹段112。
第二摇臂160为杆状,两端均设置有孔,且两个孔的轴线平行。第一摇臂150的结构同第二摇臂160的结构相同,第二摇臂160与第一摇臂150具有相同的长度。
第二摇臂160的一端和第二螺母130的铰接部132可通过销轴形成铰接连接,第一摇臂150的一端和第一螺母120的铰接部可通过销轴形成铰接连接。并且,第二摇臂160的另一端和第一摇臂150的另一端通过销轴形成铰接连接。
当丝杆110与第一螺母120和第二螺母130之间发生相对转动时,第二螺母130和第一螺母120之间相互靠近或远离,从而驱动第二摇臂160和第一摇臂150之间的夹角变小或变大,同时,第一摇臂150与第二摇臂160之间铰接的一端能够远离或靠近丝杆110。
旋转件140为筒状结构,一端敞开,另一端设置有直径小于筒内径的轴孔,该轴孔与该筒状结构同轴,其直径与丝杆110的枢轴段113的直径 相等。旋转件140的筒壁上设置有平行于其轴向的滑槽141。旋转件140的筒内径大于第二螺母130的直径。
丝杆110的枢轴段113插装于旋转件140的轴孔,且可在该轴孔中旋转。丝杆110的第一螺纹段111、第二螺纹段112及第一螺母120和第二螺母130均位于旋转件140的筒内,且第二螺母130的导向部133和第一螺母120的导向部位于旋转件140的滑槽141内。
当丝杆110通过枢轴段113与旋转件140之间发生相对转动时,滑槽141的侧壁能够作用于第二螺母130的导向部133和第一螺母120的导向部,对第一螺母120和第二螺母130产生转矩,从而驱动第一螺母120和第二螺母130相对于丝杆110转动,使第一摇臂150和第二摇臂160之间的角度变大或变小。
弹性刀片170为长条形刀片,其厚度小于宽度,当刀片受到厚度方向的力时可以发生弹性变形。弹性刀片170的垂直于厚度方向上的一个面设置有铰接部,铰接部设置有铰接孔,铰接孔的轴线方向平行于其宽度方向。弹性刀片170的末端的背向旋转件140的一侧为弧面171。
弹性刀片170的铰接部铰接于第一摇臂150和第二摇臂160的铰接处,即,弹性刀片170的铰接部、第二摇臂160和第一摇臂150同轴铰接。当弹性刀片170保持为直线状态且平行于丝杆110时,其厚度方向与旋转件140的径向方向同向。弹性刀片170的两端受到朝向丝杆110的外力作用时,能够朝向丝杆110和旋转件140弯曲,使弹性刀片170整体呈弧形。
弹性刀片170与第一摇臂150和第二摇臂160为铰接连接,当铰接点的两端受力不均时弹性刀片170可以向受力较大的一端发生转动,以减小刀片在在该端的变形,从而使刀片两端的受力趋于均衡。本实施例中,弹性刀片170是铰接在第一摇臂150和第二摇臂160的铰接处的,即三者共用一个铰轴。在一些可选实施例中,第一摇臂150或第二摇臂160的自由端还可以设置第三个孔,该孔可用于与弹性刀片170形成铰接连接。
使用时,先使第一螺母120和第二螺母130之间具有较大的距离,第一摇臂150与第二摇臂160之间具有较大的角度,以使弹性刀片170贴近旋转件140,从而使整个榨汁机刀具具有较小的径向尺寸。再将榨汁机刀 具插入至例如橙子的果实中,转动旋转件140,从而使弹性刀片170在果实内产生回转运动,对果肉进行刮削。在保持旋转件140转动的状态下,使丝杆110相对于旋转件140转动,以使第一螺母120和第二螺母130之间的距离变小,第二摇臂160和第一摇臂150之间的夹角逐渐变小,从而驱动弹性刀片170在丝杆110的径向方向上远离旋转件140,进一步对果肉进行刮削。在弹性刀片170远离旋转件140的过程中,弹性刀片170的两端会受到果肉和/或果皮内壁的阻力,使得弹性刀片170弯曲呈弧形。当弹性刀片170的中部触及果皮内壁时,弹性刀片170整体的弧形能够与果皮内壁的弧形贴合,从而完成对整个果实内部果肉的刮削。
弹性刀片170的末端的背向旋转件140的一侧为弧面171。使用时,弹性刀片170的末端的背向旋转件140的一侧与果肉或果皮之间具有较大的压力,当将该部分设置为弧面时可使该端无尖角,从而减轻刀片对果皮的破坏。在一些可选实施例中,弹性刀片170的末端具有圆滑的曲面表面,即弹性刀片170的末端为圆头,能够进一步减轻对果皮的刮削。当然,其他除去弹性刀片末端尖角的结构也可以减轻对果皮的刮削,如倒角或倒圆角结构。
在一些可选实施例中,弹性刀片170的数量为两个。对应地,第一摇臂150和第二摇臂160的数量也为两个,第一螺母120和第二螺母130上的铰接部数量也为两个。其中的一组第一摇臂150、第二摇臂160和弹性刀片170如图23所示的方式配置,另一组第一摇臂150、第二摇臂160和弹性刀片170配置在第一螺母120和第二螺母130上的另外的铰接部上,且关于丝杆110对称设置。
参考图26,图26为根据本发明一个可选实施例中的弹性刀片的结构示意图,视图方向为沿着弹性刀片的厚度方向。在本可选实施例中,弹性刀片用于连接第二摇臂和第一摇臂的部分的宽度大于其两端部分的宽度,即,弹性刀片的宽度由中间向两端递减。上述设置可以增大弹性刀片的抗扭刚度,防止弹性刀片发生扭转。
在一些可选实施例中,弹性刀片170的原始形状为弧形。弹性刀片170安装于第二摇臂160和第一摇臂150时,其弧形的曲率中心位于弹性 刀片170面向旋转件140的一侧。当第二摇臂160和第一摇臂150之间具有较大的夹角而贴近旋转件140或丝杆110时,弹性刀片170的两端会贴紧旋转件140或丝杆110,从而被迫变直,弹性刀片内部会存在内应力,使弹性刀片整体具有更高的抗扭刚度。当弹性刀片170远离丝杆110时,可以自动复原为弧形,内部应力减小,但其圆弧状结构本身可以抵抗弹性刀片发生扭转变形。
参考图27,图27为根据本发明一个可选实施例提供的榨汁机刀具的弹性刀片的截面示意图。表面192a为弹性刀片面向旋转件的一侧,表面193a为弹性刀片背向旋转件的一侧,侧面194a为面对弹性刀片的面向宽度方向上的一个侧面。侧面194a与表面193a之间为锐角,即,二者为刀刃的两个面。在本可选实施例中,表面193a上设置有凸出于其表面的筋条195a,筋条195a的延伸方向与弹性刀片的长度方向一致。筋条195a具有呈柱面或锥面状的表面,即,筋条的横截面中,其表面为弧形。筋条195a能降低弹性刀片的表面193a与果实果皮内表面的压紧程度,从而防止弹性刀片的刃口过多切入至果皮内,减轻对果皮的刮削;另外,筋条195a具有圆滑的表面,因此不会显著增大榨汁机刀具的旋转阻力;同时,筋条195a的圆滑表面还可以对附着于果实果皮内表面的果肉进行挤压榨取果汁;除此之外,筋条195a还能增大刀片的抗扭刚度,防止弹性刀片发生扭转变形。
参考图28,图28为根据本发明另一个可选实施例中的弹性刀片的截面示意图。在本可选实施例中,表面192b为面向旋转件的一侧,表面193b为背向旋转件的一侧,侧面194b为面对弹性刀片宽度方向的一个侧面。侧面194b与表面193b之间为锐角,即,二者为刀刃的两个面。表面193b整体为弧面,即,在弹性刀片的横截面上,其背向旋转件的一侧的表面形状为弧形,能防止弹性刀片的刃口对果皮的过度刮削,同时能增大刀片的抗扭刚度,防止发生扭转变形。
在一些可选实施例中,第一螺母120和第二螺母130的导向部为设置在螺母周面且平行于其螺纹孔轴线的导向平面,该导向平面相当于除去螺母圆周面表面一部分材料后形成的平台表面。对应地,旋转件140上设置有用于与该平面配合的驱动部,驱动部包括一个平行于旋转件140的旋转 轴的驱动平面,该驱动平面的延伸方向与旋转件140的旋转轴的延伸方向一致,且面向旋转件140的旋转中心。并且,第一螺母120和第二螺母130上的导向平面与螺纹孔的距离均等于旋转件140上旋转中心与驱动平面之间的距离。装配状态下,旋转件140的驱动平面与第一螺母120和第二螺母130上的导向平面贴合,旋转件140通过其驱动平面可以驱动第一螺母120和第二螺母130绕丝杆110转动,同时,第一螺母120和第二螺母130也可以与旋转件140之间(驱动平面与导向平面之间)发生相对滑动。
在一些可选实施例中,第一螺母120和第二螺母130的导向部为设置在螺母周面且平行于其螺纹孔轴线的槽,该槽贯穿螺母。对应地,旋转件140上设置有用于与该平面配合的驱动杆,该驱动杆的延伸方向与旋转件140的旋转轴的延伸方向一致。并且,该驱动杆与旋转件140的旋转轴不重合。装配状态下,旋转件140的驱动杆穿过第一螺母120和第二螺母130上的槽,可以驱动第一螺母120和第二螺母130绕丝杆110转动,同时,第一螺母120和第二螺母130的槽也可以与旋转件140的驱动杆之间发生相对的滑动。驱动杆的截面形状可以与螺母上的槽的截面相同,也可以为圆柱结构。
在一些可选实施例中,旋转件140上可以不设置轴孔,即,丝杆110与旋转件140之间不设置枢接结构,但是二者可以同轴地、可转动地连接于其他构件上,同样能形成可同轴转动的连接关系。
在一些可选实施例中,弹性刀片170固定在第二摇臂160或第一摇臂150的末端。
在一些可选实施例中,第二螺母130中的铰接部132和导向部133可以设置为一体结构,即任何能够同时实现铰接和导向作用的结构。例如,可以除去导向部133,仅保留铰接部132,且铰接部132的厚度设置为与滑槽141的宽度相当,通过铰接部132的侧面实现与旋转件140中滑槽141的抵靠接触。例如,还可以设置为,第二摇臂160的与铰接部132铰接的部位也位于滑槽141中,通过第二摇臂160的侧壁和铰接部132的侧壁分别与滑槽141的两个侧壁抵靠接触。例如,还可以除去铰接部132, 并且在导向部133上设置垂直于第二螺母130螺纹孔旋转件线的孔(但该孔不与该螺纹孔旋转件线相交,即空间垂直关系),通过该孔实现铰接,通过导向部133的两个侧面与滑槽141的两个侧壁配合实现力矩传递。
在一些可选实施例中,第二螺母130的铰接部132用于实现铰接的结构还可以为轴。

图29为根据本发明一个实施例提供的榨汁机刀具100a的结构示意图,图30为图29中挡块180a的结构示意图。图中的双点划线线圈a用于示意果实的果皮内壁轮廓。
本实施例中的榨汁机刀具100a具有与榨汁机刀具100基本相同的结构,不同之处在于,榨汁机刀具100a还包括挡块180a,弹性刀片170a的长度大于弹性刀片170。
挡块180a包括环体181a和限位部182a,本实施例中限位部182a为圆柱状结构。环体181a具有中心孔,限位部182a从环体181a的径向凸出。
挡块180a通过其中心孔安装在旋转件140的一端,挡块180a能够沿旋转件140的轴向滑动。挡块180a安装在旋转件140上,限位部182a位于弹性刀片170a的背向旋转件140的一侧,弹性刀片170a该端背向旋转件140的一面抵靠在限位部182a上。当弹性刀片170a远离旋转件140时,限位部182a能够对弹性刀片170a的一端进行限位,但不会限制其表面相对于限位部182a的滑动,从而使弹性刀片170a的端部朝向果实中心发生弯曲,可以避免弹性刀片170a对果实插入口处的果皮部的过度刮削。并且,弹性刀片170a发生弯曲后的曲率中心在弹性刀片170a的面向旋转件140的一侧,其弯曲后的弧形更接近果实果皮的形状,对果实果肉的刮削更充分。
在另一些可选实施例中,旋转件140的两端均可设置挡块,弹性刀片170或弹性刀片170a的两端分别由旋转件140两端的挡块限位。此时,弹性刀片170或弹性刀片170a的长度可以大于果实的直径,刀片的两端均由 挡块实现限位。使用时榨汁机刀具可以贯穿果实,果实位于两个挡块之间。
图31为根据本发明一个可选实施例提供的榨汁机刀具100b的结构示意图,图32为图31中挡块180b的结构示意图。
本实施例中的榨汁机刀具100b具有与榨汁机刀具100基本相同的结构,不同之处在于,榨汁机刀具100b还包括挡块180b,弹性刀片170b的长度大于弹性刀片170,以及旋转件140b的一端设置了套管部142b。
套管部142b设置在旋转件140b的一个端面上,套管部142b的内管与旋转件140b在该端上的轴孔的直径相同,可视为轴孔的进一步延伸。
挡块180b包括环体181b、孔183b和限位部182b。环体181b为盘状环结构,盘中心设置有中心孔,盘体上设置有在厚度方向上贯通的孔183b。孔183b的一个侧壁形成限位部182b。
挡块180b的中心孔套装于旋转件140b的套管部142b上,弹性刀片170b的一个端部穿过挡块180b上的孔183b,且当弹性刀片170b远离旋转件140b时,挡块180b的限位部182b会限制弹性刀片170b远离旋转件140b,但不会限制其表面相对于限位部182b的滑动,从而使弹性刀片170b发生弯曲。可以避免弹性刀片170b对果实上刀具插入口处果皮的过度刮削。
在另一些可选实施例中,旋转件140b的两端均可设置挡块,弹性刀片170或弹性刀片170b的两端分别由旋转件140b两端的挡块限位。此时,弹性刀片170或弹性刀片170b的长度可能大于果实的直径,榨汁机刀具需要贯穿果实。
图33为根据本发明另一个实施例提供的榨汁机刀具200的轴测图,图34为图33所示榨汁机刀具200的工作原理示意图。图中的双点划线线圈a用于示意果实的果皮内壁轮廓。

滑槽241用于与第二螺母230和旋转件240的导向部配合。装配状态下,第一螺母220的导向部和第二螺母230的导向部均位于滑槽241中。当丝杆210与旋转件240之间相对转动时,驱动部242的滑槽241即可驱动第二螺母230和旋转件240相对于丝杆210转动,并在丝杆210的轴向相互靠近或远离彼此。弹性刀片270在向果实的果皮方向进给时,其两端受到果肉和/或果皮的作用力发生弯曲,可形成与果实果皮内表面轮廓相适应的弧度。

第一螺母320的结构与第二螺母330的结构基本相同,不同之处在于,第一螺母320的螺纹旋向为左旋。
第一螺母320和第二螺母330分别旋合于丝杆310的第一螺纹段311和第二螺纹段312上。
旋转件340包括用于与丝杆310上的枢轴段313形成枢接的部分,该部分设置有轴孔,可与枢轴段313形成轴孔配合。旋转件340还设置有驱动杆341,驱动杆341为一细长杆结构,其直径等于第二螺母330和第一螺母320上导向部的孔的直径。驱动杆341平行于旋转件340上的轴孔,且二者的轴线的距离等于第二螺母330中螺孔331和导向部333的孔的距离。
丝杆310、第一螺母320、第二螺母330、第一摇臂350、第一摇臂350和弹性刀片370之间的连接关系与榨汁机100中对应的结构之间的连接关系相同,此处不再赘述。

驱动电机12固定于榨汁机本体11上,驱动电机12的输出轴连接有主动齿轮13。
从动齿轮14固定于旋转件240上,且从动齿轮14的转动轴线与旋转件240的转动轴线重合。从动齿轮14与主动齿轮13之间为啮合传动。
榨汁机刀具200可转动地连接在榨汁机本体11上,具体地,通过旋 转件240枢接于榨汁机本体11的孔中。
丝杆控制装置15连接于丝杆210和榨汁机本体11之间,使丝杆210与榨汁机本体11之间不发生相对转动。
当旋转件240被驱动转动时,与丝杆210之间发生相对转动。驱动部242驱动第二螺母230和第一螺母220绕丝杆210转动从而相互远离或靠近。
在一些可选实施例中,丝杆控制装置15还可以为驱动装置,可提供动力转矩以使驱动丝杆210转动,并且丝杆210的转动速度与旋转件240的转动速度设定为具有预定差值,以使丝杆210与旋转件240之间发生相对转动。
在另一些可选实施例中,丝杆控制装置15为差速装置,连接于丝杆210和主动齿轮13之间。丝杆210和旋转件240共用驱动电机12,但通过差速装置保持一定的转速差值。该差速装置可以是齿轮组,主动齿轮由主动齿轮13驱动,从动齿轮驱动丝杆210,但该齿轮组的传动比与主动齿轮13和从动齿轮14之间的传动比不等。
在一些可选实施例中,榨汁机刀具还可以为前述实施例中的榨汁机刀具100、榨汁机刀具100a、榨汁机刀具100b或榨汁机刀具300,上述榨汁机刀具中的旋转件可转动地连接在榨汁机本体11上。通过丝杆控制装置15控制丝杆的转动速度,使得旋转件转动时能够与丝杆之间产生转速差。
