Description

一种自清洗的食品加工机
本申请要求于2021年3月10日提交中国专利局、申请号为202110260188.3、发明名称为“一种不用手洗食品加工机”的中国专利申请和2021年3月26日提交中国专利局、申请号为202110330573.0、发明名称为“一种食品加工机的杯盖安全锁定方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及食品加工机领域，尤其涉及一种可自清洗且清洗彻底、粉碎效率高且安全的食品加工机。
背景技术
现有的食品加工机，一般包括主机，设于主机上的加工腔，主机内设有电机，用于驱动加工腔内的粉碎刀进行物料加工，加工腔上方盖合有杯盖。申请号为CN 201711088669.0的发明专利申请，公开一种自清洗食品加工机，包括容器、盖体和粉碎装置，盖体的侧壁内侧设有朝向盖体喷射水流的喷嘴，从而通过喷嘴对难以清洗的盖体进行充分清洗，但喷射水流只能够有效冲刷到盖体，而对加工腔的清洗效果并不能得到优化，并且该方案也无法在整体优化清洗的同时解决粉碎的问题。现有的食品加工机加工腔较深，粉碎刀带动水流进行加工腔自清洗时，沿着加工腔内侧壁越向上，水流的冲洗力度越小，使得加工腔上部难以彻底清洗，清洗效果不理想。加大粉碎刀转速用于清洗又容易导致噪音提升以及清洗水流从杯盖上的排气阀溢出的问题，还会影响到电机寿命，杯盖也难以被水流冲刷清洗干净。现有的食品加工机还存在另一个问题，加工腔既要满足基础制浆量的需求以提升用户使用体验，又要满足物料在加工腔内充分粉碎的细度和均匀性等性能要求，加工腔太大则粉碎后的物料粒度不理想，还容易加剧清洗问题，加工腔太小又难以同时满足制浆量和浆液均匀度的需求。因此，如何在实现清洗彻底的同时，提高粉碎效率和粉碎率，同时保证制浆量和浆液高均匀度，是亟待解决的问题。
另外，现有的具有自动进水、制浆，以及自动排浆和清洗的自清洗食品加工机，能够在用户不参与的情况下，完成全部工作流程。而对于杯体可拆或杯 盖可拆的自清洗食品加工机，虽然无需用户参与操作如加水或清洗等动作给用户带来了便捷，但是在全自动工作流程中，因为用户出现误操作如中途开盖或异常断电等情况，容易导致程序中断甚至制浆失败或未加工完成的浆液喷溅或异常排出等意外发生，或者机器频繁启停而延长制浆周期。因此，如何在全自动制浆清洗的同时，避免用户误操作拆卸杯体或杯盖而发生安全隐患，以及即使用户误操作依然能够在保证用户安全的基础上使得食品加工机全自动工作流程顺畅执行，仍然是亟待解决的问题。
发明内容

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
实施例一
如图1至图8所示，本发明提供一种自清洗的食品加工机，包括主机100a、加工腔200a和电机101a，加工腔内设有由电机驱动的粉碎刀201a，主机设有水箱102a，水箱通过管路与加工腔连通。本实施例中，所述电机设置于主机内，所述加工腔包括上腔体300a和下腔体400a，以及位于上腔体和下腔体之间的连接段500a。下腔体400a固定设于主机，且相对于主机顶部至少部分的下沉设置，上腔体相对于下腔体可拆卸设置，上腔体300a呈倒扣式安装于下腔体上端口处，所述连接段500a设于上腔体400a连接段500a相对于下腔体至少部分向加工腔内凸出设置。具体地，连接段500a可固定设置于上腔体400a的下端口处。连接段500a对上下腔体连接处密封，且引导清洗水流在凸出设置的连接段处改变水流方向，原本在粉碎刀201a的带动下沿着下腔体侧壁向上运行的水流在连接段处随着凸出的连接段向趋于粉碎刀旋转中心的方向倾斜并继续在粉碎刀的搅动下向上运行，从而加大了水流向上冲刷上腔体的行程和对上腔体顶壁冲洗的力度，以对上腔体进行360°无死角自动清洗。所述下腔体400a设有排浆口以及与排浆口连接的阀体组件103a，阀体组件通过进水管路与水箱102a连通，水箱内的水通过进水管路进入到阀体组件并通过排浆口进入到加工腔内，制浆完成后浆液通过阀体组件排出至接浆杯104a，清洗废水排出至余水盒105a。
在粉碎制浆过程中，至少部分向加工腔内凸出设置的连接段，能够有效将在离心力的作用下被粉碎刀甩至下腔体侧壁的物料向下以及向着粉碎刀的方向压制并将固液混合物中的固态物料聚集在下腔体内进行粉碎细化，同时还能够压制小容量浓浆使其积聚在下腔体内充分翻滚熬煮；而通过对浓浆加水制作的浆液，食品加工机的制浆容量则在下腔体容积的基础上，又有上腔体的加持，从而实现小空间粉碎和大容量制浆，同时使得浆液细腻均匀。尤其在制作低浓度浆液和果蔬汁饮品时，凸出设置的连接段能够将胡萝卜等硬质物料的粉碎颗粒进一步细化，制作出的果蔬饮品颗粒感进一步降低。
如图3和图4所示，连接段500a包括环形密封件501a，所述密封件形成加工腔内侧壁的一部分，从而参与并配合粉碎刀粉碎制浆、自动清洗等动作。环形密封件501a周向环绕式凸出于下腔体内侧壁。本实施例中，上腔体300a和下腔体400a内侧壁均设有扰流筋301a，连接段与加工腔200a内的扰流筋配合，阻碍被扰流后的水流或浆液向下回落的趋势，从而平衡上腔体300a和下腔体400a内制浆时浆液的量以及清洗时的水量分布，使得浆液均匀，清洗水流扰动充分，从而对加工腔内壁清洗力度进一步增加。
所述连接段500a的倾斜方向可以根据产品属性补偿而设定，具体地，连接段500a倾斜方向与上腔体一致，更利于引流和清洗上腔体；连接段500a竖直设置，则更加凸显并优化上腔体和下腔体之间的密封性能，尤其是上下腔体拆卸处，也就是连接段的上端处或下端处，充分保证不漏浆；连接段500a的倾斜方向与下腔体一致时，则进一步优化水流在上腔体300a和下腔体400a内的循环速度和循环效果，这是由于水流向下压制刀片的力度增加，对粉碎刀201a上表面中部则具有更好的清洗效果。本实施例中，所述上腔体300a内侧壁倾斜设置，所述下腔体400a内侧壁也倾斜设置且与上腔体内侧壁倾斜方向相反，上腔体内径向上变小设置，从而使得加工腔在所述连接段处的内径最大，所述连接段的内侧壁与上腔体内侧壁倾斜方向一致，使得连接段500a的内径呈从下向上至少部分的变小设置。
所述粉碎刀201a的顶端不高于所述连接段500a设置，所述连接段500a固定设于上腔体下端口处，连接段500a与下腔体400a侧壁上端连接处形成台阶，对水流形成有效引导，而对物料形成有效压制。下腔体400a的容积不大于所述上腔体300a和连接段容积的总和，连接段设置于加工腔特定高度处，连接段500a距离下腔体底壁的距离不大于连接段距离上腔体顶壁的距离，且粉碎刀201a顶端不高于连接段设置。基于此，额定制浆或清洗过程中，自然状态下液体液面没过连接段500a时，粉碎刀搅动还能够加剧清洗水对连接段的冲洗。本实施例中，如图4所示，连接段500a与加工腔200a底壁之间的高度为h，加工腔200a内腔高度H，1/5≤h/H≤4/5，连接段500a与粉碎刀201a顶端之间的距离为h1，1/5≤h1/h≤4/5，作为优选，10mm≤h1≤100mm，本实施例中，h为64mm，H为157mm，h1为45mm，这样设置能够最大限度地发挥连接段的清洗优势和粉碎优势之间的平衡，使得食品加工机清洗和粉碎性 能均得到有效提升。保证连接段引导清洗水流的有效性，水流在粉碎刀的带动下先触碰下腔体侧壁并向上运行触发连接段500a的引导，否则水流会直接越过连接段到上腔体内，从而无法保证对上腔体侧壁以及上腔体顶壁的清洗力度。另外，还需要保证用户拆卸上腔体后，下腔体400a有充分的空间用于容纳固体物料且上腔体300a和下腔体400a上下叠加后整个加工腔的深度满足细化粉碎和彻底清洗的要求。
如图5所示，所述密封件501a设有引导部505a，引导部505a引导被搅拌刀搅动的水流倾斜向上对上腔体300a进行清洗。所述引导部505a至少部分的向加工腔内凸出设置。所述引导部505a包括倾斜设置的引导面，所述引导面的倾斜方向和上腔体300a的倾斜方向一致，连接段500a与下腔体400a侧壁上端形成台阶，所述引导面即为所述台阶的台阶面。引导部向上延伸形成延伸部506a，所述引导部505a与竖直面之间的角度大于延伸部506a与竖直面之间的角度，至少部分的引导部和/或延伸部形成加工腔内侧壁的一部分。本实施例中，所述延伸部506a和引导部505a共同形成加工腔200a内侧壁的一部分，所述延伸部506a能够进一步延伸被引导部改变后的水流继续向上运行的趋势，同时矫正因粉碎刀高速转动以及间歇性停顿或换向导致的水流倾斜方向偏差，从而帮助水流更快速到达上腔体300a顶壁，对上腔体进行有力度的冲洗，避免顽固残余浆液或者物料颗粒附着。所述密封件501a还包括密封端部507a，所述延伸部横向弯折并向外延伸形成所述密封端部，所述密封端部507a与所述上腔体300a下端口密封抵接。本实施例中，所述密封端部即为密封端面502a，密封端面上设有多条环形密封筋508a，所述密封端部与上腔体下端口密封配合。本实施例中，当上腔体安装到位后，所述下腔体上端口抵接部分的引导部，下腔体内侧壁与向加工腔内凸出的引导部之间的距离为T，1mm≤T≤5mm，优选T为2mm，这样设置优化了连接段对清洗水流的引导，同时还能够有效保证粉碎制浆时连接段对物料的压制，使得物料聚焦下腔体粉碎，使得清洗性能和粉碎性能达到最优平衡。
密封件设有开口503a以及与开口连通的弹性变形空间504a，下腔体400a上端口至少部分地抵接密封件501a以压缩所述弹性变形空间504a，能够有效抵消密封件硬度不均、以及上腔体制造公差、上腔体和下腔体装配公差导致的密封性能下降的问题，另外，弹性变形空间的设置大大优化了用户安装手感， 弹性变形空间发生形变从而减小安装过程中密封件与下腔体上端口之间的摩擦阻力。具体的，所述引导部505a、延伸部506a和密封端部507a合为形成具有环形开口的弹性变形空间504a，所述开口位于密封件外侧。所述密封件还包括设置于密封端部的第一限位筋509a，以及设于引导部的第二限位筋510a。具体的，第一限位筋509a为沿着密封端部靠近开口端向上延伸形成的限位凸部，第二限位筋510a为沿引导部靠近开口端向上延伸形成的限位凸部，确保密封件不会上下移位或局部密封失效，从而保证密封件与上腔体和下腔体之间的压缩量均衡，避免密封件上下压缩不均衡导致密封件上下压力不均而出现液体渗漏。所述弹性变形空间内设有第三限位筋511a，所述弹性变形空间包括位于第三限位筋511a上方的安装空间和位于第三限位筋下方的形变空间，避免安装移位导致弹性变形空间余量不足，进一步保证密封性能。
所述加工腔包括设置于上腔体下端口的密封件固定装置600a，所述密封件固定装置至少部分的伸入开口503a以通过密封端部将所述密封件夹持固定在上腔体下端口处，所述密封件至少部分的外露于加工腔中，引开浆液并有效阻挡物料残渣或浆液进入到密封端面中。本实施例中，所述密封件固定装置包括支撑架601a和设置于支撑架下方的底盖602a。具体的，所述上腔体下端口设有环形底盖602a，底盖602a设有安装围边604a，密封件通过环形开口套设在所述安装围边上。所述上腔体300a下端还设有环形支撑架，支撑架601a位于底盖上方，支撑架上设有螺钉柱，底盖上设有螺钉孔，所述底盖602a与支撑架601a通过螺钉固定连接并将所述密封件至少部分的夹持固定在上腔体下端口和底盖之间。密封件可以随上腔体一起拆卸下来，避免下腔体放料时上端口残料积累，影响上下腔体安装时，所述密封件密封面的平整度，避免用户操作失误导致的漏水现象发生。支撑架601a围绕上腔体下端周侧设置，如图7所示，支撑架上设有定位结构603a，所述上腔体上设有与定位结构配合的限位结构302a。本实施例中，所述定位结构603a为多个凸出设置的定位柱，所述限位结构302a为周向设于上腔体下端外围且与所述定位柱一一配合的定位缺口，防止支撑架相对于上腔体周向转动。在生产组装食品加工机时，密封件首先套设固定于底盖602a上，支撑架套设安装到上腔体下端，密封件随底盖安装到上腔体下端口处，并与支撑架固定连接，防止密封件移位，防止密封失效，且密封件易安装，简化了用户的安装动作，避免因为安装失误导致浆液渗 漏。另外，密封件501a的安装也使得上腔体和支撑架之间的限位结构更加简化，避免藏料或形成清洗死角。
具体的，支撑架包括环形侧壁611a以及设于环形侧壁上端的上围边605a，上围边底部边缘设有向下凸出的环形定位凸台612a，上腔体下端设有限位台阶303a。本实施例中，所述限位台阶303a为设置于上腔体下端口处的翻边，所述定位缺口设置在所述限位台阶上，所述上围边605a上的定位凸台与限位台阶配合对所述支撑架进行轴向限位，上围边605a与上腔体外侧壁间隙设置，防止过定位的同时，避免将上腔体外壁刮花。所述底盖包括底盖侧壁613a，设置于底盖侧壁上端的安装围边604a，以及设置于底盖侧壁下端的下围边606a，所述底盖通过下围边606a与支撑架601a下端抵接配合。具体的，支撑架环形侧壁611a下端内侧设有上定位面，底盖下围边606a设有下定位面，上定位面和下定位面抵接配合，从而在底盖和支撑架通过螺钉锁紧固定的同时，将密封件501a锁紧固定在底盖安装围边顶面和上腔体下端口的端面之间。
所述安装围边顶部设有环形限位槽607a，所述密封件密封端部底面上设有与所述限位槽配合的环形限位凸筋608a，密封件501a通过开口503a套设到底盖上时，限位凸筋608a卡入限位槽对密封件进行限位。如图8所示，所述开口上端设有与上腔体下端限位台阶外围配合的第一限位筋509a，开口下端设有与底盖配合的第二限位筋510a，底盖安装围边的底面设有弧形凸台，弧形凸台与所述底盖侧壁之间形成卡槽614a，所述第二限位筋510a卡入所述卡槽614a内，对密封件引导部进行限位。当上腔体安装到下腔体上时，引导部抵接所述下腔体上端口。
密封件固定装置设有上旋合结构401a，下腔体上端口设有与上旋合结构配合的下旋合结构609a，所述上腔体和下腔体旋合连接并使得密封件密封上腔体和下腔体连接处。本实施例中，如图6所示，所述上旋合结构设置于底盖侧壁内侧，所述下旋合结构609a设置于下腔体侧壁上端外侧，下腔体为铝压铸制成，下腔体嵌设有发热管，上腔体为玻璃腔，且侧壁和顶壁连为一体，顶壁上设有投料口304a以及排气塞305a，投料口与排气塞之间设有密封部，加工可视化和清洗可视化效果好。当上旋合结构旋入下旋合结构609a中时，下腔体上端口与密封件引导部抵接并压缩所述弹性变形空间，使得上下腔体连接处被可靠密封，同时又能够抵消上腔体制造公差导致的装配精度误差。支撑架 601a和底盖602a上均设有加强筋615a，所述加强筋纵向设置，支撑架上的加强筋从支撑架环形侧壁内侧向上延伸至上围边底面且与定位凸台齐平，底盖上的加强筋从底盖侧壁外侧向下延伸至下围边顶面。上旋合结构为旋扣，下旋合结构为卡扣，所述卡扣的上表面低于所述下腔体上端口端面设置，使得旋扣旋合和下腔体上端口端面密封功能独立且可靠，不受干涉。主机上设有锁定装置106a，对上腔体进行锁定，底盖上设有与锁定装置配合的锁止结构616a。上腔体旋合安装到位后，所述锁止结构616a与锁定装置106a配合，阻止上电后上腔体被意外拆卸。
本实施例中，所述底盖602a的下围边上设有漏水孔610a，避免因上腔体制作高差而到时液体进入到支撑架和底盖之间，漏水孔610a及时将残水排出，避免密封件固定装置内因残水滞留而产生异味。用户在使用过程中如果将上腔体拆卸后意外淋水，残水也能够通过漏水孔及时排出，保证配件清洁，保证用户使用安全。

所述锁止联动装置还包括设置于主机/下腔体的锁止触发件。所述方法还包括：锁止步骤：锁止触发件与锁止连杆抵接并使锁止连杆将杯盖锁定在杯体上端口处，以阻止杯盖拆卸。触发步骤执行使得杯盖安装到位后才能触发安全开关，将杯体组件内的粉碎刀与用户隔绝，确保用户第一道安全屏障。触发步骤中，既可以由安全连杆直接触发安全开关，或者通过安全开关触发件间接触发，这样不仅确保触发步骤的执行可靠性，还能够使得杯体组件安装到主机/下腔体时更加省力。锁止步骤则将杯体组件锁止在主机上，保证用户无论是在加工过程中还是加工后的短时间内，均无法触及高速粉碎刀，形成第二道安全屏障，有效避免用户使用过程中拆卸而导致机械伤害，防止制浆过程中浆液喷溅，并且防止自动清洗过程中高温水喷溅。与此同时，保证两道安全屏障彼此之间不产生机械干涉而导致其中之一失效。所述方法还包括加工步骤：主机内的控制模块根据用户输入的操作指令控制食品加工机执行对应的加工动作，如制作豆浆，或米糊，或果蔬汁或干磨等。
所述锁止步骤中，杯体通过安装部安装到主机上，所述锁止触发件驱动所述锁止连杆向上运动，并保持锁止连杆至少部分的凸出设置在触发锁合部运动路径上的状态。
作为实施方案之一，对不设置锁止开关的食品加工机，锁止触发件固定设置于主机/下腔体，杯体安装到主机上时，第一联动步骤和第二联动步骤执行，且在杯盖和杯体安装到主机/下腔体时，锁止触发件将锁止连杆持续顶起并保 持对杯盖的锁止状态。这种情况下，锁止触发件固定设置于主机/下腔体，而且用户需要先将杯盖安装到主机上，触发第一和第二联动步骤之后，再将杯体组件安装到主机/下腔体上以触发锁止步骤，否则锁止步骤先被触发，锁止连杆凸出设置在触发锁合部的运动路径上将阻止杯盖的安装。优选地，所示锁止连杆包括第一锁止连杆和第二锁止连杆，第一锁止连杆和第二锁止连杆之间设有弹性复位件。这种情况下，为用户体验更加便捷的拆装体验，在所述第二联动步骤中，所述触发锁合部接触并驱动所述第一锁止连杆向下运动。在第二联动步骤中，锁止触发件驱动所述第一锁止连杆和第二锁止连杆向上运动并使第一锁止连杆至少部分的凸出设置在杯盖触发锁合部的运动路径上。当锁止步骤被触发时，第一锁止连杆和第二锁止连杆联动顶起使得第一锁止连杆凸出设置在触发锁合部的运动路径上，由于第一锁止连杆和第二锁止连杆之间设有弹性复位件，即使先安装杯体到主机上，第一连杆凸出设置，但此时触发步骤和锁止步骤并未执行，因为杯盖未安装，所示安全连杆未被下压，也就是说第一联动步骤和第二联动步骤也未执行，此时安装杯盖，触发锁合部执行第一联动步骤，而且在弹性复位件的作用下，触发锁合部可以在锁止触发件持续顶起的情况下下压所述第一锁止连杆，此时弹性复位件被压缩，并在触发锁合部与第一锁止连杆错位设置且杯盖安装到位后，第一锁止连杆向上回弹，第一锁止连杆上端位于触发锁合部后侧以将杯盖锁止防止旋转拆卸，为用户提供更大的操作自由度和双重安全保障。
作为另一实施方案，所述锁止联动装置包括设置于主机/下腔体的锁止开关和锁止触发件，所述锁止步骤中，杯体通过安装部安装到主机上，锁止开关驱动所述锁止触发件向上运动并抵接锁止连杆下端，以保持锁止连杆至少部分的凸出设置在触发锁合部运动路径上的状态。在锁止步骤执行完成后，锁止触发件凸出并锁止杯盖，从而对杯体和杯盖的拆卸或二次安装形成有效阻挡，控制模块控制食品加工机在整个全自动加工清洗的特定过程或程序中执行所述锁止步骤，从而充分考虑用户可能的误拆装动作。另外，当锁止触发件未锁止加工腔时，加工动作不能启动，而且所述锁止触发件仍然可以弹性下压从而避免对杯体拆装形成阻挡，为用户提供执行加工程序前拆卸杯体和杯盖的适宜手感的反悔操作。
所述锁止步骤在触发步骤之后执行，也就是说，第二道安全屏障建立在第 一道安全屏障的基础上，从而为用户提供充分的操作空间，在第二道安全屏障未建立时，即使安全开关未触发，用户仍然可以拆卸杯体组件，用户替换或者加固态料等反悔操作或附加操作，充分考虑用户操作的便捷性和人性化的场景体验，整机启动加工动作前执行所述锁止步骤，优化用户体验的同时保证安全。
进一步的，控制模块控制所述锁止步骤在输入操作指令之后且在加工动作执行前执行。为优化自动制浆，食品加工机包括水箱、水泵和输水管路，从而使得控制模块控制水箱内的水通过输水管路自动加入到加工腔内，食品加工机的加工动作包括自动进水、加热、粉碎等和制浆相关的动作，而控制模块控制锁止步骤在输入操作指令后且在加工动作执行前执行，不仅为用户提供继续加入或补充物料的时间，还进一步为用户提供二次反悔操作的时间和自由，直至加工动作执行前，锁止步骤才真正将杯体组件/上腔体锁止，此时不允许任何拆卸杯体组件/上腔体的动作，即使用户误操作希望打开加工腔，也会被锁止联动装置阻止，从而在为用户提供充分加料时间的同时，避免用户按下操作指令有误需要进一步修改或矫正操作指令，如重新配置加工参数或食谱等动作，对食品加工机的全自动智能服务进行优化升级。
进一步的，所述食品加工机安全锁定方法还包括解锁步骤：所述控制模块在加工动作结束并间隔时间t后，控制锁止联动装置解锁所述杯体组件/上腔体，控制模块控制所述锁止开关取消对锁止触发件的持续顶起状态，由于锁止触发件与锁止开关之间设有弹性复位件，使得锁止开关解除锁定，锁止触发件仍然在弹性复位件的作用下向上凸出设置，此时锁止触发件仍然保持凸出设置在杯体组件/上腔体的拆装路径上的状态，但是当用户拆卸杯体组件/上腔体时，锁止触发件被下压并解除阻挡从而使得杯体组件/上腔体能够顺利拆除，间隔时间范围为1.5s≤t≤10s。本实施例中所述加工动作是指食品加工机执行完成完整的与用户输入指令对应的加工程序，本实施例中，t设定为3s。在解锁步骤中，控制模块控制锁止联动装置延时解锁，对于自清洗的食品加工机加工腔，能够保证浆液或者清洗水充分排出，且加工腔内的粉碎刀能够有充分的时间降速或停止，解锁步骤完成后，用户轻松拆卸杯体组件/上腔体从而避免受到高速粉碎刀的伤害。如果用户输入的指令是执行干磨功能，则对于干磨加工腔，还能避免磨粉喷出。本实施例中，所述锁止开关为电磁铁，所述锁止触发件包括电磁铁触发连杆，所述电磁铁和电磁铁触发连杆之间设有所述弹性复位件。
所述食品加工机具有预约功能，如果用户需要预约制浆，则在加工步骤中，还对应包括预约步骤，所述锁止步骤在预约步骤开始执行后启动。本实施例中，更进一步的，所述锁止步骤在预约步骤执行完成后，加工动作开始之前启动。在根据用户输入指令设定的预约时间内，加工程序尚未正式启动，所述锁止步骤仍未执行，在预约倒计时的时间内，用户仍然可以拆卸下杯体组件/上腔体进行加料等操作，直至预约时间到需要进行自动加水等加工动作前，控制模块控制所述锁止步骤执行，将杯体组件/上腔体锁定，从而避免加工过程中用户误开启而导致机械危险发生。
作为实施方案之一，所述锁止连杆和安全连杆沿杯盖旋合安装方向设置，所述第一联动步骤在第二联动步骤之后执行，这样设置可以最大程序的缩小锁止连杆和安全连杆在周向上的相对距离，从而缩小连杆安装空间，同时保证第一联动步骤和第二联动步骤彼此不受干涉。第一联动步骤和第二联动步骤先后执行，在时间上和空间上，触发锁合部顺序接触锁止连杆和安全连杆，接触并不一定触发，这取决于触发步骤和锁止步骤的启动和执行节点，而分别接触锁止连杆和安全连杆能够为用户提供安装杯盖是否到位的手感提示，顺序接触还减轻了安装阻力，以及最大化的减小杯体组件的径向尺寸，也就是安装锁止连杆和安全连杆及相应弹性复位件的空间。
可以理解的，作为本实施例的另一种导向结构的方案，所述触发锁合部包括凸起，所述导向结构包括锁止导向结构，锁止导向结构包括锁止槽206b和设置于锁止槽内的第二导向段205b，所述第二导向段设有第二导向斜面且第二导向斜面与锁止槽的开口端连接。
可以理解的，所述安全开关触发件和锁止触发件在径向上对齐设置。
可以理解的，当上腔体与下腔体安装并合围形成所述加工腔时，所述上腔体通过安装部旋合安装于下腔体，所述触发锁合部还可以同时接触所述锁止触发件和安全开关触发件；或者，所述上腔体通过安装部旋合安装于下腔体，所述触发锁合部先接触安全开关触发件并触发所述安全开关，后接触所述锁止触发件。
可以理解的，所述上腔体替换为杯体组件500b时，所述锁止连杆和安全连杆沿杯盖旋合安装方向设置，第一联动步骤在第二联动步骤之前执行；或者，所述锁止连杆和安全连杆沿杯体径向设置，所述第一联动步骤和第二联动步骤 同时执行。当锁止连杆和安全连杆径向设置时，相对角速度相同，杯盖旋合时能够在时间上同时接触两者，从而避免因为先后触发顺序而导致的其中之一没有被接触或者接触后锁止连杆未顺利回弹而导致后续锁止步骤执行失败的情况。
可以理解的，本发明所述的杯盖锁定方法适用于自清洁食品加工机，也适用于传统的需要手动加水加料、手动倒浆和清洗的普通食品加工机。
可以理解的，主机和/或杯体上设有对所述安全联动装置和/或锁止联动装置复位的弹性复位件600b。
可以理解的，所述杯体组件可以包括多个且相互替换使用，例如用于冷热加工、干磨、绞肉、切菜等。
除上述优选实施例外，本发明所保护的技术方案，并不局限于上述实施例，应当指出，任意一个实施例中的多个技术方案的结合，以及任意一个实施例的技术方案与其他一个或多个实施例中技术方案的结合，在本发明的保护范围内。虽然，上文中已经用一般性说明及具体实施例对本发明作了详尽的描述，但在本发明基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本发明原则的基础上所做的这些修改或改进，均属于本发明要求保护的范围。
