技术领域
本公开涉及饮料制备技术领域，特别涉及一种水路切换装置及饮料机。
背景技术
随着现代人对咖啡饮品的热爱程度不断攀升，咖啡机的市场也在快速增长，对于商务咖啡机而言，其应用场景比较复杂，这对咖啡机自身的拓展能力有所挑战，特别是水的使用。商务场所不同于商业场所，大部分的区域，比如办公室不具备连接自来水的条件，而如果咖啡机仅使用自身的水箱时，由于水箱容量较小，影响续航能力；通常做不了几杯咖啡水箱的水就被用完了，用户可能需要频繁对水箱进行水体补给等工作，由此衍生出了桶装水的概念，咖啡机可以通过水管连接到大的矿泉水桶上，商家以此来解决无自来水情况下提高咖啡机续航的能力。
然而，对于传统的咖啡机，为了实现该功能(矿泉水桶与水箱的切换)都是采用两个球阀，或者一个球阀配合一个单向阀的模式来实现，即便有单个阀体实现功能切换，也使得阀体的结构过于复杂，造成此组零件成本的上升。

具体实施方式
为了便于理解，下面对传统的水路切换装置进行示例性说明。
图1中示出的咖啡机自动进水切换装置，水箱9装在导水座10上、导水座10出水端接头与快接胶管11用硅胶管3连接；快接胶管11与水龙头组件12的进水端之间连接；水龙头组件12的出水端与快接管连接；水龙头组件12出水端上的快接管与三通接头5用硅胶管3连接。硅胶管的进水端插入桶装水1，硅胶管的出水端与两通接头2进水端连接；两通接头2的出水端与单向阀4进水端接头用硅胶管3连接。水龙头上的手柄13拨到关闭关水状态，桶装水1内有水，水泵8正常进行抽水工作，水泵8的抽水力会克服单向阀4里的弹簧21的力；此时水泵8所抽的水为桶装水内的水来制作咖啡饮品。水龙头上的手柄13拨到打开通水状态，桶装水1内有水，水泵8正常进行抽水工作；此时水泵8所抽的水为水箱内的水来制作咖啡饮品；此种状态水泵不会抽桶装水的原因为，需要克服单向阀4组件里的弹簧21的力，而水箱9里只要有水，就会对水泵提供有微小压力的水，水泵会抽用水箱9水制作咖啡饮品。
如上自动进水切换装置，结构比较复杂，而且如果单向阀组件里的弹簧失效，则有可能产生无法抽水的问题。
有鉴于此，本公开提供一种适用于饮料机的水路切换装置。以下将结合附图所示的具体实施方式对本公开进行详细描述。但这些实施方式并不限制本公开，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本公开的保护范围内。
应该理解，本文使用的例如“上”、“上方”、“下”、“下方”等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个单元或特征相对于另一个单元或特征的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。
本公开实施方式中的水路切换装置可以应用于咖啡机中，下面以应用于咖啡机的水路切换装置为例进行说明。应当理解，本公开中实施方式中的水路切换装置也可以单独地使用或者应用于其它设备中。
本公开具体实施方式中的水路切换装置，参照图2到图5所示，在本实施例中，水路切换装置100包括阀体20、连接于阀体20上的切换柄30以及活动设置于阀体20内的阀芯50。阀体20上设有相互成角度的第一进水通道21和出水通道23。切换柄30上形成有第二进水通道32，阀芯50连接于切换柄30，切换柄30带动阀芯50 在第一位置和第二位置之间活动，从而切换第一进水通道21和出水通道23连通或者第二进水通道32和出水通道23连通。在第一位置，第一进水通道21和出水通道23连通并且第二进水通道32和出水通道23断开；在第二位置，第一进水通道21和出水通道23断开并且第二进水通道32和出水通道23连通。
通过在切换柄30上设置进水通道，阀体20上无需再设置额外的进水通道，切换柄30带动阀芯50活动可以实现不同进水水路的切换，减少了零件的数量，优化了整体结构。通过切换柄30带动阀芯50运动至不同位置即可实现切换，使用可靠，可以根据需要随时进行切换。
具体的，阀体20包括筒状的主体，阀体20具有沿箭头X方向所示的轴向以及垂直于轴向的径向。沿主体轴向的一端形成第一进水通道21。第一进水通道21的直径小于主体的直径，方便与第一供水源进行管路连接，而且可以在主体内对应第一进水通道21的位置形成台阶部211，以便对阀芯50在阀体20内的安装进行轴向的定位。主体的周壁形成出水通道23，出水通道23沿着主体径向延伸。第一进水通道21的延伸方向和出水通道23的延伸方向大致垂直，方便阀体20的制造。
阀芯50具有第一连接通道52以及出口522，出口522连通第一连接通道52，第二进水通道32与第一连接通道52连通，在第二位置，出口522和出水通道23连通。其中切换柄30可以部分伸入到第一连接通道52内，以更可靠的连接阀芯50并且第二进水通道32与第一连接通道52能够连通，只需要控制出口522和出水通道23连通与否，即可进行两条水路的切换，结构简单，操作方便。
切换柄30枢转连接于阀体20，阀体20的主体上还设有与第一进水通道21连通的第二连接通道22，阀芯50设置于第二连接通道22内，切换柄30与阀芯50沿周向固定，切换柄30可操作地带动阀芯在第一位置和第二位置之间旋转。通过旋转切换柄30带动阀芯50进行水路切换，结构简单，操作方便。在其它实施方式中，也可以是切换柄旋转带动阀芯移动的方式进行水路切换，或者是切换柄移动带动阀芯旋转的方式进行水路切换，还可以是切换柄移动带动阀芯移动的方式进行水路切换，只要能够实现两个进水通道和出水通道择一连通即可。
其中，第二连接通道22设置于阀体20上与第一进水通道21相对的一端，特别地，第一进水通道21的中心线与第二连接通道22的中心线平行或者共线。特别地，切换柄30上的第二进水通道32的中心线也可以设置成与第一进水通道21的中心线平行或者共线，即阀体20沿轴向的两端分别形成两个通道。出水通道23设置于阀 体20的径向。阀体20上仅设置三个通道即可实现水路的切换，结构简单并且占用空间更小，而且方便阀体20的制造以及方便阀芯50和切换柄30的安装。
进一步的，阀芯50构造为与第二连接通道22配合的管状，第二连接通道22在临近第一进水通道21处设有台阶部211。阀芯50的一端抵接在台阶部211上，阀芯50的另一端与切换柄30沿周向固定，方便切换柄30带动阀芯50旋转。本实施方式中优选的，阀芯50还包括进口通道54以及开口521，开口521连通进口通道54，进口通道54与第一连接通道52相对设置，第一进水通道21与进口通道54连通，在第一位置，开口521与出水通道23连通。也就是说，阀芯50的两端形成有分别与第一进水通道21和第二进水通道32的两个通道，一个通道与出口522连通，另一通道与开口521连通，只需使阀芯50运动到出口522或者开口521位置对应，则切换到相应的进水通道与出水通道23连通。在其它实施方式中，也可以仅设置一个通道和与该通道对应的出口，该通道可以选择与第一进水通道21和第二进水通道32之一连通，出口与出水通道位置对应即连通两个进水通道之一和出水通道；只需要出口与出水通道位置错开，即可连通两个进水通道之另一和出水通道。
具体的，开口521和出口522设置于阀芯50的周壁上，出口522和开口521沿阀芯50轴向的位置对应并且沿周向呈预设间隔设置，该预设间隔满足阀芯50在第一位置和第二位置时，出口522和开口521分别与出水通道23位置对应。在其它实施方式中，当阀芯设置成被切换柄带动沿轴向移动时，出口和开口也可以沿着阀芯50的轴向间隔设置。
阀芯50内设有挡板51，挡板51断开第一进水通道21和第二进水通道32的连通。若阀芯设置成只有一个出口时，挡板51可以是阀芯50的端板。本实施方式中，特别地，挡板51设置于开口521和出口522之间，即开口521和出口522位于挡板51的两侧，开口521和出口522通过挡板断开连通。第一进水通道21通过开口521与出水通道23连通，第二进水通道32通过出口522与出水通道23连通。当阀芯50旋转时，只需要转到开口521或出口522与出水通道23连通，即可实现一水路连通的同时另一水路断开。
具体的，当使用饮料机的内部水源，操作切换柄30带动阀芯50旋转到如图6所示的位置，开口521与出口通道23连通，内部水源的水可从第一进水通道21进入到阀芯50的进口通道，并从开口521流到出口通道23。而出口522被阀体20的周壁封堵，使得从第二进水通道32到出水通道23的流路断开。需要切换到外部水 源时，在外部水源的管路连接到切换柄30后，操作切换柄30带动阀芯50旋转到如图5所示的位置，出口522与出口通道23连通，外部水源的水可从第二进水通道32进入到阀芯50的第一连接通道，并从出口522流到出口通道23。而开口521被阀体20的周壁封堵，使得从第一进水通道21到出水通道23的流路断开。
为了方便操作，开口521和出口522沿阀芯50的周向间隔180度设置，即开口521的中心和出口522的中心沿阀芯50的径向在同一条直线上，阀芯50旋转180度实现开口521或出口522与出水通道23对应，方便阀芯50的定位。开口521的孔径和出口522的孔径与出水通道23的孔径大致相等，在阀芯50旋转的过程中，开口521的孔径或出口522的孔径与出水通道23的孔径会经过完全错开、部分重叠、完全重叠的过程，当开口521的孔径或出口522的孔径与出口通道23的孔径完全重叠时为流量最大的状态。可以根据需求来设置切换柄30旋转的不同位置，从而实现开口521和出口522与出口通道23的孔径不完全重叠，以调节自第一进水通道21和第二进水通道32到出口通道23的流量。可以在切换柄的不同的旋转位置，设置对应不同流量的挡位，方便在切换水路的同时能够对流量进行调节。
如图5和图6所示，挡板51构造成成弧型，挡板51的表面形成为弧面，方便引导液体的流动，同时以简单的结构将挡板51两侧的第一进水通道21与第二进水通道32断开。弧面包括分别自开口521的一侧和出口522的一侧沿反方向延伸的两个弧面部511，两个弧面部511的中间通过大致平面的平面部过渡连接，从而可以形成自进水通道到出水通道23的过渡缓冲，减小水流对挡板51的冲击力，从而增长阀芯50的使用寿命。
如图7所示，在另一实施例中，挡板51a沿着阀芯50的径向呈角度倾斜，挡板51a的表面设置成斜面，同样可以方便引导液体的流动，同时以简单的结构将两侧的通道断开。
如图8所示，在再一实施例中，挡板51b设置成台阶型，挡板51b的表面设置成台阶面，同样可以将两侧的通道断开，并且结构简单，方便制造。
继续参照图3以及图9，阀体20连接切换柄30的端面上设有沿周向延伸的导向槽25。切换柄30上设有凸块35，凸块35沿着导向槽25运动以限制切换柄30在预设范围内旋转。在本实施例中，预设范围定义为切换柄30带动阀芯50旋转，开口521与出水通道23对齐的位置和出口522与出水通道23对齐的位置之间所旋转的角度。本实施例中，开口521和出口522沿阀芯50的径向设置于同一条直线上，即开 口521和出口522沿阀芯周向间隔180度，那么切换柄30也同样被限定在180度的范围内旋转。切换柄30沿一个方向旋转到凸块35与导向槽25的边缘抵接，被限制无法继续旋转，从而实现切换到位，操作方便可靠。
切换柄30包括插入阀体20的连接部302以及形成手柄311的操作部301。操作部301包括内外间隔嵌套的内管312和外管313，内管312形成第二进水通道32，外管313的外壁上径向延伸出手柄311，方便用户操作切换柄30旋转。操作部301包括环绕外管313设置的端板315，端板315的一侧与手柄311相连，端板315的另一侧抵接在阀体20上，实现了切换柄30在阀体20上沿轴向的定位，设置手柄311的操作部301形成旋钮，方便操作。
连接部302的外侧设有卡块333，阀芯50轴向一端的边缘设有卡槽53，卡块333插入到卡槽53内以实现切换柄30与阀芯50沿周向的固定。本实施方式中特别地，卡块333设置两个，两个卡块333相对于切换柄30的旋转轴线呈中心对称，卡槽53也同样设置两个，与对应的卡块333配合，可以使切换柄30与阀芯50的连接更加可靠。特别地，为了增强切换柄30和阀芯50的密封，连接部302的一部份插入到阀芯50内并且在两者之间设置第一密封圈61，防止切换柄30和阀芯50之间出现漏水现象。
进一步的，在阀芯50和第二连接通道22之间设置第二密封圈62，第二密封圈62可以设置两个，两个第二密封圈62被开口521和出口522前后间隔开。在开口521和出口522的周围，设置第三密封圈63。当开口521或出口522与出水通道23位置对齐时，第三密封圈63实现开口521和出水通道23之间或者出口522和出水通道23之间的密封。通过设置两道密封，确保了了自进水通道到出水通道23的液体输送更加可靠。优选地，在出水通道23的入口端设置十字筋26，方便在切换水路的时候，第三密封圈63不会被出水通道23的入口卡住，使水路切换的过程更加可靠。
本实施例中，水路切换装置还包括限位件70。切换柄30的连接部302的外侧设有定位凹部37，阀体20上设有定位孔27，限位件70穿过定位凹部37并伸入到定位凹部37内，即限位件70位于定位孔27和定位凹部37内，限制切换柄30沿轴向的移动。特别地，定位凹部37可以是连接部302上外径相对于相邻部分较小的部分，不会影响切换柄30的旋转。本实施例中，连接部302上设有围绕切换柄30周向的径向边沿335。卡块333自径向边沿335一侧沿轴向凸伸，定位凹部37位于径向边 沿335的另一侧，限位件70伸入到定位凹部37内，径向边沿335与限位件70轴向抵接，从而限制切换柄30与阀体20沿轴向分离。限位件70大致呈U型，包括两个限位臂，定位孔27设置两个，每个限位臂分别位于定位孔27和定位凹部37内。通过两个限位臂对切换柄30的轴向移动进行限位，只需操作一侧便可实现限位件的安装，从而切换柄30的安装方便并且旋转更加可靠。限位件70作为切换柄30的固定装置，可有效防止切换柄30往外退出。
为了方便水路切换装置的安装，阀体20一般连接在饮料机内部的支架上，阀体20的外侧设有紧固件穿孔28，紧固件沿第一方向穿过紧固件穿孔28以固定阀体20，限位件70也沿着第一方向插入定位凹部37，方便水路切换装置的组装。特别地，限位件70沿与第一方向相反的第二方向插入定位凹部37。也就是说，限位件70的插入方向与紧固件的插入方向相反，从而可以先安装限位件70再连接紧固件，避免阀体20安装到支架后，限位件70从阀体上意外脱落或者误操作取下。
本公开的其它实施例还提供一种饮料机，参考图10所示，该饮料机包括本公开提供的水路切换装置100，优选的，第一进水通道21连接饮料机1的内部水源，第二进水通道32连接外接水源，出水通道23连接饮料机内的出水管路。其中，内部水源可以是安装在饮料机1上的水箱11，外接水源可以是矿泉水桶3或者净化后的自来水管路。通过将第二进水通道32连接外接水源，可以方便用户操作，优化产品的结构从而降低制造成本。
上述水路切换装置100适用于各种类型的咖啡机，如全自动咖啡机、胶囊咖啡机、半自动咖啡等。当然，上述水路切换装置不限于在咖啡机中的应用，也可以用于其它饮料机，如茶饮机或者其它冲泡饮料的装置。
上述实施例中，通过在切换柄30上设置进水通道，阀体20上无需再设置额外的进水通道，即切换柄30和其中一个进水通道结合实现不同进水水路的切换，减少了零件的数量，优化了整体结构。进一步地，切换柄30带动阀芯50活动即可实现不同水源(路)的切换，结构操作简单，且使用稳定可靠，可以根据需求随时进行切换，实现了咖啡机在不同应用场景下的快速适用，满足不同场景及客户的需求。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本公开的可行性实施方式的具体说明，它们并非用以限制本公开的保护范围，凡未脱离本公开技艺精神所作的等效实施方式或变更均应包含在本公开的保护范围之内。
