除非特别说明或另有定义，本实用新型所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
为叙述方便，除另有说明外，下文所说的上下方向与图1本身的上下方向一致，下文所说的左右方向与图1本身的左右方向一致。
如图1至图6所示，一种防滴阀，包括阀体10和安装在阀体10上的接液 器20；阀体10上开设有进液通道101；阀体10上设有导流筋30。
导流筋30位于接液器20的上方，用于接纳导流筋30上掉落的液滴。进液通道101具有送液口1011，导流筋30的一端设于送液口1011处，导流筋30的另一端沿背离进液通道101的方向延伸，接液器20上开设有废料口201。
酿造咖啡的时候，咖啡机将咖啡液输送到进液通道101，咖啡液从送液口1011处连续流出，在导流筋30的表面张力的作用下，咖啡液从送液口1011处连续流出时附着在导流筋30上，在连续流出的咖啡液的推动下，附着在导流筋30的咖啡液顺着导流筋30的延伸方向流动，最后流到杯子等指定的容器中，实现咖啡的酿造。当酿造完成之后，咖啡机停止向进液通道101输送咖啡液，送液口1011处没有咖啡流出，咖啡液断流，导流筋30上附着的咖啡液没有了推力，导流筋30上附着的咖啡液在重力的作用下掉在接液器20上并从废料口201流出，防止咖啡液顺着导流筋30继续流动，从而防止咖啡液沿着导流筋30一滴一滴地流出。
具体的，在一些实施例中，进导流筋30沿背离进液通道101的方向倾斜向上延伸。本实施例中，接液器20连接在阀体10上并位于送液口1011处的下方。液通道位于导流筋30的右端，导流筋30的从右往左向上倾斜延伸，咖啡液从进液通道101向左流动，连续流出的咖啡液顺着导流筋30向左移动，当停止输送咖啡液的时候，导流筋30上的咖啡液出现断流，咖啡液在重力的作用下，导流筋30上的咖啡液顺着导流筋30向右往靠近进液通道101的方向流动，流动到送液口1011处时，由于进液通道101内填满咖啡液，咖啡液在重力的作用下往下掉入接液器20上并从废料口201流出。
具体的，在一些实施例中，接液器20上设有引流通道202，引流通道202用于接纳咖啡液。引流通道202的一端与进液通道101连通，引流通道202另一端沿背离进液通道101的方向倾斜向上延伸。导流筋30的上端与阀体10一体成型，导流筋30的下端沿背离进液通道101的方向倾斜向上延伸。沿着背离进液通道101的方向上，引流通道202的底部和导流筋30的下端同时沿背离进液通道101的方向倾斜向上延伸，导流筋30的下端位于引流通道202内并与引流通道202的底部相对设置，导流筋30的下端与引流通道202的底部 之间存在间隙，咖啡液附着在导流筋30的下端并在间隙内顺着导流筋30流动。
具体的，在一些实施例中，阀体10、接液器20、导流筋30一体成型。导流筋30的上端与阀体10连接，导流筋30的下端沿着靠近引流通道202的底部的方向延伸并位于引流通道202内。导流筋30的下端的横截面呈等腰梯形，导流筋30的下端的宽度从上往下逐渐降低，利于咖啡液附着在导流筋30的下端并顺着导流筋30流动。
在酿造咖啡过程中，咖啡从进液通道101到达引流通道202时，咖啡可以利用导流筋30的表面张力克服出引流通道202的高度差，使咖啡从导流筋30流出。酿造咖啡完成后，残留咖啡液会一滴一滴慢慢流出，此部分咖啡液无法克服导流筋和引流通道202的高度差，咖啡液从废液口流出，再流入其它废水容器内，减少酿造完成后的咖啡滴停时间，不用去等待咖啡慢慢滴完。
具体的，在一些实施例中，导流筋30具有与引流通道202的底部相对设置的导流面301；导流面301沿着引流通道202的延伸方向倾斜向上延伸。导流面301位于导流筋30的下端，导流面301从右往左远离进液通道101并倾斜向上。导流面301向上倾斜的角度大于或等于引流通道202的底部向上倾斜的角度，在背离进液通道101的方向上，导流面301与引流通道202的底部之间的距离保持不变或者逐渐增大，防止因导流面301与引流通道202的底部之间的距离变小而妨碍咖啡液的流动。本实施例中，导流面301与引流通道202的底部之间的距离保持不变，保证咖啡液的流动速率。
具体的，在一些实施例中，导流面301在重力方向的投影位于引流通道202内，导流面与进液通道101的内壁相切或位于送液口1011围合形成的区域内。导流面301的高度低于进液通道101的顶部或与进液通道101的顶部平齐，保证从进液通道101的送液口1011出来的液体流到导流面301上，避免因导流面301高度太高导致送液口1011出来的液体直接落入引流通道。优选的，导流面与进液通道101的内壁相切，避免导流筋阻碍液体从送液口1011流出。
具体的，在一些实施例中，接液器20呈半圆管状，引流通道202的横截面呈半圆形，进液通道101的横截面呈圆形。在导流筋30延伸方向的投影上， 进液通道101位于引流通道202的边缘围合形成的区域内。引流通道202包括第一液流槽2021和第二液流槽2022，第一液流槽2021具有第一端和第二端，进液通道101的第一端与进液通道101连通，进液通道101的第二端与第二液流槽2022通连通；第一液流槽2021的第一端的内壁与进液通道101的内壁相接，第一液流槽2021的第二端的内壁与第二液流槽2022的内壁相接。连续的咖啡液顺着导流筋30流动到导流筋30末端的时候，前的咖啡液在后面咖啡液的推动以及惯性的作用下，从导流筋30的左端飞出，并顺着第二液流槽2022左端的出液口2023飞出到指定的容器，完成咖啡的酿造。当咖啡液断流时，在重力的作用下，咖啡液流到导流筋30的左端就掉在第二液流槽2022上并顺着第二液流槽2022的底壁向第一液流槽2021流动，最后从第一液流槽2021处的废液口流出，咖啡液断流时会直接掉在引流通道202，不会沿着导流筋30流动，从而保证咖啡酿造完成之后咖啡一滴一滴流出。
沿着背离进液通道101的方向，第一液流槽2021的横截面逐渐增大。使得沿着导流筋30冲出的咖啡液流动更顺畅。
具体的，在一些实施例中，接液器20上设有引流板203；第二液流槽2022的一端与第一液流槽2021连通，第二液流槽2022的另一端具有出液口2023，引流板203的一端与出液口2023的下边缘连接，引流板203的另一端沿着背离出液口2023的方向向下延伸。引流板203的横截面从上往下逐渐减小。连续的咖啡滴沿着导流筋30流动时从出液口2023处冲出下落，然后顺着引流板203流向相应的容器。
具体的，在一些实施例中，废料口201开设在第一液流槽2021的第一端的两侧。废料口201位于引流通道202的下端，有利于将不要的咖啡液全部排出。废料口沿背离所述进液通道的方向延伸，导流筋延伸的长度大于或者等于废料口延伸的长度的二分之一。
出液口2023的高度高于废料口201。咖啡很容易沿着导流筋23流向出液口2023，而不会直接从废料口201排出；当咖啡的流速很低，咖啡可以通过了废料口201，但无法通过出出液口2023时，咖啡会从废料口201流出。
具体的，在一些实施例中，防滴阀还包括具有出液槽401和废液槽402的基座40；阀体10安装在基座40上，出液口2023与出液槽401连通，废液槽402与废料口201连通。酿造咖啡的时候，顺着导流筋30流动并从出液口2023飞出的咖啡液落入到出液槽401，最后出液槽401内的咖啡液到达指定的容器中完成酿造。完成酿造之后剩余的咖啡液从废料口201流到废液槽402收集。
具体的，在一些实施例中，阀体10上设有卡槽102。阀体10通过卡槽102卡入出液槽401的边缘，使得阀体10安装在基座40上。出液槽401和废液槽402中间通过隔板403分隔，隔板403上设有卡孔，接液器20卡设在卡孔内，实现接液器20的定位。
具体的，在一些实施例中，卡槽的内壁设有倒勾，出液槽401的内壁设有倒勾卡入的勾槽，防止阀体与基座脱离。进液通道的外表面为阶梯轴，便于阀体的固定。
具体的，在一些实施例中，出液槽401的底壁设有倾斜的引流面，引流面位于引流板的下方，引流面的下端设有集液槽，集液槽下方设有开设有放液孔，咖啡液通过放液孔落入用户的杯子内。
具体的，在一些实施例中，废料口201具有呈台阶状的引流面，引流面从上往下延伸，引导剩余的咖啡液流入废液槽402，防止咖啡液飞溅。
具体的，在一些实施例中，沿着靠近接液器的方向，进液通道的横截面先逐渐递减然后保持不变，提高进液通道输送咖啡液的液压，保证连续的咖啡液顺着导流筋流动。
如图1所示，一种防滴阀的防滴方法，包括如下步骤：
启动咖啡机，咖啡机向进液通道101内输送咖啡液，随着咖啡机不断地输送咖啡液，进液通道101内的咖啡液向送液口1011处流动。
咖啡机不断地输送咖啡液，液体从送液口1011处连续流出，连续流出的咖啡液体在导流筋30的表面张力的作用下，液体沿着导流筋30流动，实现咖啡液体的连续输送；连续的咖啡液在导流筋30的末端飞出，最后从引流通道 202的出液口2023顺着引流板203流到出液槽401中再流入用户的咖啡杯内，完成咖啡的酿造。
完成咖啡的酿造后，咖啡机关闭，咖啡机停止向进液通道101内输送液体，送液口1011处无咖啡液继续流出，导流筋30上的咖啡液断流，导流筋30上的咖啡液在重力的作用下掉落在接液器20的引流通道202内，从而能够防止液体沿着导流筋30滴出，接液器20的引流通道202内的咖啡液最后从废料口201排出到废液槽402。
以上实施例也并非是基于本实用新型的穷尽性列举，在此之外，还可以存在多个未列出的其他实施方式。在不违反本实用新型构思的基础上所作的任何替换与改进，均属本实用新型的保护范围。
