Description

一种饮品酿造机构及咖啡机
本申请要求于2024年04月22日提交到中国国家知识产权局、申请号为“202420841420.1”、发明名称为“一种饮品酿造机构及咖啡机”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
本申请涉及但不限于咖啡机技术领域，具体是指一种饮品酿造机构及咖啡机。
背景技术
目前，咖啡机越来越受到消费者的喜爱。相关技术中，咖啡机包括饮品酿造机构，咖啡原料放置于饮品酿造机构的酿造仓内，用于盛装咖啡的容器放在酿造仓的出液口下方。酿造仓内加入热水，对咖啡原料进行萃取以得到咖啡，在萃取的过程中咖啡经出液口进入用于盛装咖啡的容器内。但是，由此得到的咖啡口味单一，难以满足不同用户的口味需求。
发明内容
本申请所要解决的技术问题是提供一种饮品酿造机构及咖啡机，可以丰富咖啡的风味，以满足不同用户的口味需求。
本申请实施例提供了一种饮品酿造机构，包括：酿造本体，酿造本体设有酿造仓以及与酿造仓连通的出液口；止漏阀，活动安装于出液口处，并设有出液通道，出液通道设置成能够与出液口连通以排出酿造本体内的液体；和驱动机构，与止漏阀相连，设置成驱动止漏阀相对酿造本体运动以控制出液通道与出液口之间的通断以及调整出液通道的出液流速。
本申请实施例提供的饮品酿造机构，包括酿造本体、止漏阀和驱动机构。酿造本体设有酿造仓和出液口。酿造仓内用于盛装制备咖啡的原料，如咖啡豆和热水，萃取得到的咖啡经出液口排出酿造仓，经止漏阀的出液通道进入盛装咖啡的容器(如咖啡壶)内，供用户饮用。酿造仓可以呈漏斗状，出液口可以设置在酿造仓的底部。酿造仓的内壁面可以设置导流筋。
止漏阀用于控制出液口的通断。当止漏阀的出液通道与酿造仓的出液口连通时，出液口被打开，使得酿造仓内的咖啡可以排出。当止漏阀的出液通道与酿造仓的出液口断开时，出液口被关闭，使得酿造仓内的液体不能排出，以避免盛装咖啡的容器取走后酿造仓继续向下滴落液体(如剩余的咖啡、或者酿造仓清洗完的余水等)导致打湿桌面或台面。
驱动机构用于驱动止漏阀运动，来调节止漏阀与酿造本体的相对位置，实现止漏阀对出液口的开闭控制，以及实现出液流速的调节。驱动机构可以为电驱动机构，这样便于实现止漏阀的自动控制，无需用户手动调节，有利于提高用户的使用体验。
相关技术中，出液口处没有设置止漏阀，或者止漏阀只有开闭两种状态，因此出液流速是恒定的，故而咖啡口味也是单一的。而本申请实施例中，止漏阀可以打开，也可以关闭，关闭可以实现咖啡的焖蒸效果。并且，出液通道的出液流速可以调节，而出液通道的出液流速与萃取得到的咖啡的浓度相关。当出液流速较小时，用于萃取咖啡的液体在酿造仓内的停留时间较久，萃取得到的咖啡浓度较高，咖啡口味较为醇厚。当出液流速较大时，用于萃取咖啡的液体在酿造仓内的停留时间较短，萃取得到的咖啡浓度较低，咖啡口味偏淡。因此，通过调整出液通道的出液流速，即可调整咖啡的浓度，使咖啡具有焖蒸可控性，进而丰富咖啡的风味，以满足不同用户的口味需求。

具体实施方式
以下结合附图对本申请的原理和特征进行描述，所举实例只用于解释本申请，并非用于限定本申请的范围。
如图1至图6所示，本申请实施例提供了一种饮品酿造机构100，包括：酿造本体1、止漏阀2和驱动机构3。
其中，酿造本体1设有酿造仓11以及与酿造仓11连通的出液口111，如图5和图6所示。
止漏阀2活动安装于出液口111处，并设有出液通道2112。出液通道2112设置成能够与出液口111连通以排出酿造本体1内的液体。
驱动机构3与止漏阀2相连，设置成驱动止漏阀2相对酿造本体1运动以控制出液通道2112与出液口111之间的通断以及调整出液通道2112的出液流速。
本申请实施例提供的饮品酿造机构100，包括酿造本体1、止漏阀2和驱动机构3。酿造本体1设有酿造仓11和出液口111。酿造仓11内用于盛装制备咖啡的原料，如咖啡豆和热水，萃取得到的咖啡经出液口111排出酿造仓11，经止漏阀2的出液通道2112进入盛装咖啡的容器(如咖啡壶200)内，供用户饮用。酿造仓11可以呈漏斗状，出液口111可以设置在酿造仓11的底部。酿造仓11的内壁面可以设置导流筋112。
止漏阀2用于控制出液口111的通断。当止漏阀2的出液通道2112与酿造仓11的出液口111连通时，出液口111被打开，如图4和图6所示，使得酿造仓11内的咖啡可以排出。当止漏阀2的出液通道2112与酿造仓11的出液口111断开时，出液口111被关闭，如图3和图5所示，使得酿造仓11内的液体不能排出，以避免盛装咖啡的容器取走后酿造仓11继续向下滴落液体(如剩余的咖啡、或者酿造仓11清洗完的余水等)导致打湿桌面或台面。
驱动机构3用于驱动止漏阀2运动，来调节止漏阀2与酿造本体1的相对位置，实现止漏阀2对出液口111的开闭控制，以及实现出液流速的调节。驱动机构3可以为电驱动机构3，这样便于实现止漏阀2的自动控制，无需用户手动调节，有利于提高用户的使用体验。
相关技术中，出液口处没有设置止漏阀，或者止漏阀只有开闭两种状态，因此出液流速是恒定的，故而咖啡口味也是单一的。而本申请实施例中，止漏阀2可以打开，也可以关闭，关闭可以实现咖啡的焖蒸效果。并且，出液通道2112的出液流速可以调节，而出液通道2112的出液流速与萃取得到的咖啡的浓度相关。当出液流速较小时，用于萃取咖啡的液体在酿造仓11内的停留时间较久，萃取得到的咖啡浓度较高，咖啡口味较为醇厚。当出液流速较大时，用于萃取咖啡的液体在酿造仓11内的停留时间较短，萃取得到的咖啡浓度较低，咖啡口味偏淡。因此，通过调整出液通道2112的出液流速，即可调整咖啡的浓度，使咖啡具有焖蒸可控性，进而丰富咖啡的风味，以满足不同用户的口味需求。
在一些示例性的实施例中，止漏阀2包括阀芯21。阀芯21设有出液通道2112以及与出液通道2112连通的进液口2111，如图5、图6和图7所示。进液口2111供酿造仓11内的咖啡等液体进入出液通道2112内。
阀芯21设置成可移动地安装于出液口111处，以控制进液口2111的开闭以及调整进液口2111的打开面积，进而控制出液通道2112与出液口111之间的通断以及调整出液通道2112的出液流速。
驱动机构3与阀芯21相连，设置成驱动阀芯21相对酿造本体1移动。
当止漏阀2的进液口2111与酿造仓11的出液口111连通时，酿造仓11内的咖啡等液体能够进入出液通道2112内，实现酿造仓11的出液口111与出液通道2112的连通。当止漏阀2的进液口2111与酿造仓11的出液口111断开时，酿造仓11内的咖啡等液体不能进入出液通道2112内，实现酿造仓11的出液口111与出液通道2112的隔断。
通过控制止漏阀2相对于酿造本体1的移动幅度，可以调整进液口2111的打开面积，进而能够调整进入出液通道2112的液体流量，从而实现出液流速的调节。
当然，止漏阀2的运动形式不限于移动方式，比如：也可以包括转动形式，通过转动止漏阀2能够调节进液口2111的打开面积，进而能够调整进入出液通道2112的液体流量，从而实现出液流速的调节；也可以既包括转动也包括移动，通过转动和移动止漏阀2能够调节进液口2111的打开面积，进而能够调整进入出液通道2112的液体流量，从而实现出液流速的调节。
在一些示例性的实施例中，驱动机构3包括：驱动件31和传动组件。驱动件31与传动组件相连，设置成驱动传动组件运动。传动组件与阀芯21相连，设置成带动阀芯21相对酿造本体1移动。
传动组件包括传动件32和连动件33。传动件32与驱动件31相连，设置成在驱动件31的驱动下沿第一方向运动。连动件33与传动件32及阀芯21相配合，设置成在传动件32的带动下沿第二方向移动，以带动阀芯21相对酿造本体1沿第二方向移动。第二方向不同于第一方向。
这样便于根据需要合理选择驱动件31的种类、合理布置驱动件31的位置，有利于优化饮品酿造机构100的结构和布局。
在一些示例性的实施例中，传动件32包括驱动滑块321，如图5、图6、图9至图11所示。驱动滑块321设置成在驱动件31的驱动下沿第一方向滑动。驱动滑块321设有驱动斜面3212，如图5、图10和图13所示。连动件33设有配合斜面3311，如图5和图11所示。驱动斜面3212设置成与配合斜面3311相贴合，以带动连动件33沿第二方向移动。
换言之，传动件32与连动件33通过楔形斜面的配合，实现传动件32沿第一方向的移动转化为连动件33沿第二方向的移动。第二方向可以与第一方向相互垂直。
当然，传动件32与连动件33的配合形式不限于此。比如：传动件32可以为齿轮，连动件33可以为齿条，齿轮沿第一方向转动，带动齿条沿第二方向移动，齿条带动阀芯21沿第二方向移动。
在一些示例性的实施例中，连动件33包括配合滑块331以及设于配合滑块331的出液嘴332，如图5、图14和图15所示。配合滑块331设有配合斜面3311。第二方向为出液口111的轴向。出液嘴332与出液通道2112连通，并与阀芯21的底部相抵靠，如图5和图6所示。出液口111的轴向通常为竖直方向，故第二方向为竖直方向。第一方向可以为水平方向。
这样，酿造仓11内的咖啡(或其他液体)经止漏阀2的出液通道2112排出后，可以经出液嘴332向下排出。这样有利于咖啡顺畅排入用于盛装咖啡的容器内，有利于避免传动组件的设置影响咖啡的顺利排出。
在一些示例性的实施例中，阀芯21包括阀杆211，如图5和图7所示。阀杆211沿第二方向插装于出液口111。进液口2111设于阀杆211的侧壁，出液通道2112设于阀杆211内。
如图5和图7所示，阀芯21还包括套设于阀杆211外侧并与阀杆211相连的抵接部212。抵接部212与阀杆211合围出容纳槽2121，容纳槽2121的底部设有排液口2122。出液嘴332的顶部与抵接部212相抵靠，且出液嘴332还与排液口2122连通。
如图3和图5所示，当止漏阀2处于断开出液通道2112与出液口111的位置时，进液口2111位于酿造仓11外侧，处于关闭状态。当止漏阀2向上移动时，进液口2111向上移动。当进液口2111开始进入酿造仓11内时，即可与出液口111连通，处于打开状态，如图4和图6所示。阀芯21的上移程度不同，进液口2111进入酿造仓11内的面积不同，则进液口2111的打开面积不同。
进液口2111的数量可以为多个。多个进液口2111可以沿阀芯21的周向间隔设置，多个进液口2111也可以沿阀芯21的轴向间隔设置，多个进液口2111也可以沿阀芯21的周向和轴向间隔设置。
容纳槽2121的设置，便于阀杆211与出液口111之间的间隙的咖啡进入容纳槽2121，再经容纳槽2121的排液口2122排入出液嘴332内，避免阀芯21与出液口111的间隙外漏的液体到处洒落。排液口2122的数量可以为多个，多个排液口2122可以沿容纳槽2121的周向间隔设置。
在一些示例性的实施例中，如图5所示，止漏阀2还包括：第二密封件22，套装于阀芯21，设置成在止漏阀2处于断开出液口111与出液通道2112的位置时密封出液口111。第二密封件22的外直径可以大于出液口111的直径，阀杆211至少一部分的外直径可以小于出液口111的直径。这样阀杆211可以沿着出液口111上下移动，当第二密封件22抵住出液口111时可以关闭并密封出液口111，如图5所示。第二密封件22位于酿造仓11内侧，则向下运动至最终位置时关闭出液口111。
如图5和图6所示，饮品酿造机构100还包括：第二弹性件23，与阀芯21相配合，设置成利用其复位弹力带动止漏阀2向断开出液口111与出液通道2112的方向运动。这样有利于止漏阀2稳定停留在关闭出液口111的位置。当然，止漏阀2也可以不包括第二弹性件23，利用止漏阀2的重力保持在关闭出液口111的位置。
阀芯21的抵接部212还可以用于与第二弹性件23相配合。第二弹性件23可以为弹簧，弹簧套设在阀杆211外侧，一端与抵接部212相抵靠，另一端可以与酿造本体1相抵靠并位于酿造仓11外侧。在阀芯21向上运动的过程中，第二弹性件23被压缩，储存弹性势能。在阀芯21向下运动的过程中，第二弹性件23释放弹性势能，向阀芯21提供向下运动的作用力，有利于阀芯21稳定保持在关闭出液口111的位置。抵接部212与阀杆211可以为一体式结构，也可以为分体式装配结构。
第二密封件22可以为密封圈。阀杆211可以设有密封槽2113，如图5和图7所示，第二密封件22套设在密封槽2113处。当止漏阀2向下运动至关闭出液口111的位置时，第二密封件22与酿造仓11的内底壁相抵靠以密封出液口111，如图5所示。安装过程中，可以先将阀杆211的顶部由下向上穿过出液口111，然后再将第二密封件22由上向下套装在阀杆211上。松开后，止漏阀2可以在重力以及第二弹性件23的作用力下稳定地处于关闭出液口111的位置。
在一些实施例中，如图3和图4所示，酿造本体1包括酿造杯和底座。酿造杯包括酿造仓11以及套设在酿造仓11外侧的杯壳12。酿造仓11与杯壳12可以为一体式结构，也可以为分体式装配结构。酿造仓11的底部设有出液口111。底座套装在杯壳12底部内侧，并与酿造杯固定连接。底座设有与出液口111对应连通的避让空间，如图5和图6所示。止漏阀2位于酿造仓11外的部分可以隐藏在避让空间内。酿造仓11的外底壁设有嵌套设置的第一空心柱114和第二空心柱115，如图5所示，第一空心柱114的内部空间与出液口111对应连通。第一空心柱114和第二空心柱115也位于避让空间内。阀杆211穿设于第一空心柱114。第二空心柱115插装于阀芯21的容纳槽2121内。第二弹性件23的上端限位于第一空心柱114与第二空心柱115之间的间隙内。酿造仓11的内底壁设有台阶槽113，如图5所示。当止漏阀2向下运动到关闭出液口111的位置时，第二密封件22位于台阶槽113内。阀杆211可以为阶梯轴，包括大轴段和小轴段。进液口2111位于小轴段，这样便于咖啡顺畅进入出液通道2112和容纳槽2121。
在一些示例性的实施例中，如图2所示，饮品酿造机构100还包括：安装座4，驱动机构3安装于安装座4。安装座4设有沿第一方向延伸的滑槽44和沿第二方向延伸的导向孔411。驱动滑块321限位于滑槽44，设置成沿滑槽44滑动。出液嘴332穿设于导向孔411，设置成沿导向孔411移动。
安装座4能够作为驱动机构3的安装载体，对驱动机构3起到支撑作用和保护作用，还可以对驱动滑块321和出液嘴332起到导向作用和限位作用，有利于提高驱动机构3的使用可靠性。
在一些示例性的实施例中，如图5和图6所示，安装座4包括：底壳42和盖壳41。盖壳41与底壳42盖合连接，并与底壳42合围出安装腔43，如图6所示。滑槽44设于安装腔43内。导向孔411设于盖壳41。驱动机构3的至少一部分位于安装腔43内。
这样，安装座4能够对驱动机构3起到较好的保护作用，也有利于提高饮品酿造机构100外观的简洁性，从而有利于提高产品的美观度。
其中，底壳42和盖壳41可以单独加工成型，有利于降低加工难度。底壳42和盖壳41可以通过螺接、铆接、卡接、插接等方式固定在一起。其中，盖壳41可以设置两条第一导向筋，两条第一导向筋之间形成滑槽44。底壳42可以设置两条第二导向筋423，如图9所示，两条第一导向筋之间形成滑槽44。第一导向筋和第二导向筋423可以对应设置相抵接，也可以止口配合。这样，底壳42和盖壳41都可以对驱动滑块321起到限位作用和导向作用。滑槽44的两端可以设置止挡部441，如图9所示，对驱动滑块321的起始位置和最终位置进行限位。
如图5和图8所示，盖壳41可以设置限位槽414，第一密封件35可以为密封圈，第一密封件35的局部限位于限位槽414，并套设在出液嘴332插入导向孔411内的部分与导向孔411的孔壁之间。
在一些示例性的实施例中，驱动滑块321和配合滑块331均位于安装腔43内。
出液嘴332沿第二方向贯穿配合滑块331。如图5、图14和图15所示，出液嘴332包括位于配合滑块331靠近止漏阀2一侧(即上侧)的进液段3321以及位于配合滑块331远离止漏阀2一侧(即下侧)的出液段3322。出液段3322的底部可以沿周向间隔设有多个出口。进液段3321穿设于导向孔411。
其中，出液嘴332与配合滑块331可以为一体式结构，也可以为分体式装配结构。如图5所示，出液嘴332可以设置成阶梯结构，进液段3321的流通面积大于出液段3322的流通面积。换言之，进液段3321较粗，以保证出液通道2112及容纳槽2121的咖啡能够顺畅进入出液嘴332内；出液段3322较细，有利于咖啡顺畅进入用于盛装咖啡的容器内，避免洒落。如图5和图15所示，出液嘴332还可以包括位于进液段3321与出液段3322之间的过渡段3323，过渡段3323可以设置成漏斗形，便于咖啡汇集进入出液段3322。
驱动滑块321设有用于避让出液段3322的第一避让孔3211，如图9、图10、图11和图13所示。第一避让孔3211可以沿着第一方向贯穿驱动滑块321远离驱动件31的一端。
底壳42设有与出液段3322对应设置的第二避让孔422，如图5所示。基于出液通道2112与出液口111相隔断，出液段3322穿设于第二避让孔422。第二避让孔422可以为圆形孔。
在一些示例性的实施例中，配合滑块331的底部设有环形的避让槽3312，如图5、图11和图14所示，避让槽3312套设于出液段3322的外侧。底壳42设有环形的限位凸台421，如图5所示，限位凸台421围设出第二避让孔422。基于出液通道2112与出液口111相隔断，限位凸台421嵌入避让槽3312内，如图5所示。这样有利于提高出液口111关闭状态下出液嘴332和配合滑块331的位置稳定性。
在一些示例性的实施例中，驱动机构3还包括：第一弹性件34和第一密封件35，如图5和图6所示。
第一弹性件34与连动件33相配合，设置成利用其复位弹力带动连动件33沿第二方向朝远离阀芯21的方向运动。配合滑块331的顶面可以设置限位凹槽3314，如图5和图15所示。第一弹性件34可以为弹簧，套设在出液嘴332的进液段3321外侧，第一弹性件34的下端嵌入配合滑块331的限位凹槽3314内，第一弹性件34的上端与盖壳41相抵靠，可以套在下述盖壳41的限位台阶415外侧。限位凹槽3314可以位于第二安装槽3313的径向外侧。
如图6所示，第一密封件35套设于出液嘴332与导向孔411之间，设置成密封出液嘴332与导向孔411之间的间隙。
在连动件33向上运动的过程中，第一弹性件34被压缩，储存弹性势能。在连动件33向下运动的过程中，第一弹性件34释放弹性势能，向连动件33提供向下运动的作用力，有利于连动件33稳定保持在与底壳42相抵靠的位置。
当然，驱动机构3也可以不包括第一弹性件34，利用连动件33的重力保持在与底壳42相抵靠的位置。
在一些示例中，如图5所示，第一密封件35包括环状的密封主体351以及分别设于密封主体351轴向两端的第一唇边352和第二唇边353，第一唇边352和第二唇边353都沿密封主体351的径向朝外延伸。盖壳41的外顶壁凹设有第一安装槽，如图5和图8所示，第一唇边352限位于第一安装槽内。盖壳41内顶壁可以向下凸设限位台阶415，如图5所示，第二唇边353与限位台阶415的下端面相抵靠。配合滑块331的上表面可以凹设有第二安装槽3313，如图5和图15所示，第二安装槽3313用于与第二唇边353相配合。当阀芯21向上运动至最终位置，第二唇边353嵌入第二安装槽3313内，如图6所示，定位出液嘴332的最终位置。
在一些示例性的实施例中，如图5、图6和图12所示，驱动件31包括：驱动电机311、以及与驱动电机311相连的丝杆312。驱动滑块321内设有螺纹孔，丝杆312与螺纹孔通过螺纹连接。
驱动电机311驱动丝杆312转动，丝杆312带动驱动滑块321沿第一方向滑动。丝杆312可以为单头丝杆312，也可以为双头丝杆312或更多头丝杆312。通过调整驱动电机311的转动幅度，可以调整丝杆312的转动幅度，进而提高整驱动滑块321的滑动幅度，进而调整连动件33和止漏阀2的升降幅度。
驱动件31还可以包括位于驱动电机311与丝杆312之间的齿轮传动机构，这样便于调节传动比。
如图8和图9所示，驱动机构3还可以包括与驱动电机311电连接的连接器36。安装座4可以设有安装缺口413，如图8所示，连接器36可以穿过安装缺口413伸出至安装座4外，便于与咖啡机机座300内的主控板电连接。机座300可以对应设置连接器36，通过连接器36的对接实现驱动机构3与主控板的电连接，使得主控板可以控制驱动机构3。
在一些示例性的实施例中，驱动滑块321内设有安装沉孔3213，如图13所示。安装沉孔3213内设有螺母322，如图5和图6所示，螺母322设有螺纹孔。驱动滑块321内还设有与螺纹孔连通的第三避让孔3214，如图5所示，第三避让孔3214设置成避让丝杆312穿过螺母322的部分。这样有利于简化驱动滑块321的结构，便于驱动滑块321加工成型。
螺母322可以通过螺接、铆接、卡接等方式与驱动滑块321固定连接。比如：安装螺母322设有两个孔，通过两个螺钉323(如图10所示)与驱动滑块321固定连接。螺母322也可以与驱动滑块321通过包塑等工艺一体成型。
在一些示例性的实施例中，如图9和图10所示，饮品酿造机构100还包括：位置检测机构5，设置成直接或间接检测止漏阀2的位置。
位置检测机构5可以直接检测止漏阀2的位置，则位置检测机构5可以设置在止漏阀2的运动路径上。由于止漏阀2的位置与驱动机构3的状态具有对应关系，故位置检测机构5也可以通过检测驱动机构3来间接检测止漏阀2的位置，比如通过检测传动件32或者连动件33的位置来间接检测止漏阀2的位置。位置检测机构5可以安装在安装座4上。
在一个示例中，驱动滑块321在起始位置与最终位置之间往复滑动。当驱动滑块321处于起始位置时，连动件33和止漏阀2也处于起始位置，此时止漏阀2关闭出液口111。当驱动滑块321处于最终位置时，连动件33和止漏阀2也处于最终位置，此时止漏阀2打开出液口111，且出液通道2112的出液流速最大。位置检测机构5可以包括第一位置传感器和第二位置传感器。第一位置传感器设置成检测处于起始位置的驱动滑块321，第二位置传感器设置成检测处于最终位置的驱动滑块321。位置传感器的具体形式不受限制，可以为接触式传感器，也可以为渐近式传感器，也可以为其他种类的传感器等。
在其他示例中，位置检测机构5包括角度传感器，角度传感器用于检测驱动电机311的转动角度或者用于检测丝杆312的转动角度。
在另一些示例性的实施例中，止漏阀2与驱动机构3集成为电动阀。电动阀可以为但不限于电动流量阀。电动阀的结构形式不受限制，可以为电磁阀，也可以为其他种类的阀。
如图1至图6所示，本申请实施例还提供了一种咖啡机，包括：机座300，如上述中任一项的饮品酿造机构100，安装于机座300。
本申请实施例提供的咖啡机，因包括上述实施例中任一项的饮品酿造机构100，因而具有上述一切有益效果，在此不再赘述。
在一些示例性的实施例中，咖啡机还包括：控制装置(图中未示出，可以为主控板)，与饮品酿造机构100的驱动机构3电连接，设置成根据设定程序控制驱动机构3，可以控制驱动机构3的启停以及工作参数(如速度、时间、功率等)。
这样，可以将不同风味咖啡的酿造程序存储在控制装置中，通过控制装置自动控制驱动机构3，以制备不同风味的咖啡，从而有利于提高用户的使用体验。
在一些示例性的实施例中，如图1至图4所示，咖啡机还包括咖啡壶200，咖啡壶200可以放置在饮品酿造机构100下方，用于盛装饮品酿造机构100排出的咖啡。咖啡机还包括加水机构400，加水机构400与酿造仓11连通，设置成向酿造仓11加水。加水机构400的出水口可以位于酿造仓11上方，能够以花洒的形式向酿造仓11内加水。控制装置还与加水机构400电连接，可以控制加水机构400的启停以及工作参数(如温度、时间、流量等)。
该咖啡机的工作原理如下：
如图3和图5所示，在初始状态下，驱动滑块321、配合滑块331、出液嘴332、止漏阀2均位于起始位置，止漏阀2的第二密封件22压住出液口111，以关闭出液口111，将出液口111与止漏阀2的出液通道2112隔断。此时，第一弹性件34和第二弹性件23可以处于自然状态或者弱压缩状态。出液嘴332、配合滑块331和止漏阀2的位置处于运动范围内的最低位置。出液嘴332的出液段3322插入底壳42的第二避让孔422内，底壳42的限位凸台421插入配合滑块331的避让槽3312内。
当用户需要咖啡时，加水机构400向酿造仓11内加水，驱动电机311动作，驱动丝杆312转动，丝杆312带动驱动滑块321向左滑动，驱动滑块321带动配合滑块331和出液嘴332向上移动，出液嘴332顶着止漏阀2向上移动，使第二密封件22离开出液口111以打开出液口111，且阀杆211的进液口2111上升开始进入酿造仓11内，实现出液口111与出液通道2112的连通。随着止漏阀2向上运动，进液口2111进入酿造仓11内的部分逐渐增多，则进液口2111的打开面积逐渐增大，出液通道2112的出液流速逐渐增加。根据用户选择不同的咖啡风味，驱动电机311转动不同幅度，使得驱动滑块321能够滑动不同幅度，带动配合滑块331、出液嘴332、止漏阀2上升不同幅度，进液口2111打开不同幅度，形成不同的出液流速，产生不同口味的咖啡。在配合滑块331、出液嘴332、止漏阀2上升的过程中，第一弹性件34和第二弹性件23的弹性变形量逐渐增大，压缩量逐渐增大，储存弹性势能。
当驱动滑块321向左滑动至最终位置(如图4和图6所示)，配合滑块331、出液嘴332、止漏阀2也上升至最终位置。此时，进液口2111的打开面积最大，出液通道2112的出液流速最大。此时，第一密封件35的第二唇边353嵌入第二安装槽3313内。配合滑块331上升到最终位置，使得出液嘴332的出液段3322脱出底壳42的第二避让孔422且底壳42的限位凸台421脱出配合滑块331的避让槽3312。
当不需要咖啡时，需要关闭出液口111，驱动电机311反向转动，带动驱动滑块321反向滑动，配合滑块331、出液嘴332、止漏阀2可以在重力以及第一弹性件34、第二弹性件23的复位弹力作用下向下移动，复位至起始位置。
