在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。

在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定” 等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
下面结合图1和图2对根据本发明实施例的阀体100进行详细描述，该阀体100可以应用在咖啡机上用于管路的换向。
根据本发明实施例的阀体100，可以包括壳体110、弹性帽120和驱动装置13。
其中，如图1和图2所示，壳体110上设有至少一组接口111，每组接口111包括进口111a和出口111b。
也就是说，壳体110上可以设有一组接口111，也可以设置有多组接口111。每组接口111之间可以设有一个流通通道，或多个接口之间共用一个流通通道。液体或气体可以从进口111a流入流通通道中，然后气体或液体可以从出口111b流出。当阀体100具有用于流通气体的一组接口111时，用于流通气体的接口111的进口111a为进气口101，用于流通气体的接口111的出口111b为排气口102。当阀体100具有用于流通液体的一组接口111时，用于流通液体的接口111的进口111a为进水口104，用于流通液体的接口111的出口111b为出水口105。
弹性帽120的至少一部分设置在壳体110内，驱动装置13用于驱动弹性帽120发生弹性形变以阻隔进口111a和出口111b。
例如，可以是弹性帽120的一部分发生形变以阻隔进口111a和出口111b，也可以是弹性帽120整体发生弹性形变以阻隔进口111a和出口111b；弹性帽120可以将进口111a封堵以阻隔进口111a和出口111b，也可以将出口111b封堵以阻隔进口111a和出口111b，也可以将进口111a和出口111b之间的通道封堵以阻隔进口111a和出口111b。
具体地，驱动装置可以为液压驱动装置或气压驱动装置，当驱动装置为液压驱动装置时，驱动装置可以驱动液体进入到弹性帽120的内部，使得弹性帽120的内部压强大于弹性帽120的外部压强，进而弹性帽120发生形变以阻隔进口111a和出口111b；驱动装置不工作时，液体可以从弹性帽120的内部排出，进而弹性帽120回复到初始形状，进口111a和出口111b得以连通。
当驱动装置为气压驱动装置时，驱动装置可以驱动气体进入到弹性帽120的内部，使得弹性帽120的内部压强大于弹性帽120的外部压强，进而弹性帽120发生形变以阻隔进口111a和出口111b；驱动装置不工作时，气体可以从弹性帽120的内部排出，进而弹性帽120回复到初始形状，进口111a和出口111b得以连通。
在本发明的具体示例中，驱动装置为气压驱动装置，例如驱动装置可以为气泵。当然，可以理解的是，设计人员可以根据实际情况对驱动装置的种类进行选择，这里不作具体限定。
根据本发明实施例的阀体100，通过驱动装置驱动弹性帽120发生形变以阻隔或连通进口111a和出口111b，该阀体100结构简单、成本低廉，进而在一定程度上降低了咖啡机整机的成本。
在本发明的一些实施例中，弹性帽120为硅胶件。由此，弹性帽120性能稳定，成本低廉，且弹性帽120具有良好的弹性，保证了阀体100稳定安全地工作。
当然，本领域普通技术人员可以理解的是，弹性帽120为硅胶件只是本发明的一个具体实施方式，并不是对本发明所作的限定。例如，弹性帽120还可以为橡胶件。
在本发明的一些实施例中，如图1和图2所示，弹性帽120上设有弹性变形面121，在驱动装置驱动弹性帽120时，弹性变形面121发生弹性形变以阻隔进口111a和出口111b。换言之，在驱动装置工作时，弹性帽120只有一部分发生形变以阻隔进口111a和出口111b。由此，弹性帽120可以只将弹性变形面121的部分构造为弹性件，由此可以降低弹性材料的使用，至少在一定程度上降低了阀体100的成本。
在本发明的一些实施例中，弹性帽120内设有腔体1011，驱动装置与腔体1011相连以改变腔体1011内的气体压力。例如，驱动装置可以向腔体1011内泵入气体，使得腔体1011内的气体压力增大，进而使弹性帽120发生弹性形变以阻隔进口111a和出口111b；驱动装置不工作时，弹性帽120可以在自身回弹力的作用下回复到初始状态，进而进口111a和出口111b可以连通。
或者，驱动装置可以与腔体1011相连以改变腔体内的液体压力。例如，驱动装置可以向腔体1011内泵入液体，使得腔体1011内的液体压力增大，进而使弹性帽120发生弹性形变以阻隔进口111a和出口111b；驱动装置不工作时，弹性帽120可以在自身回弹力的作用下回复到初始状态，进而进口111a和出口111b可以连通。
具体地，如图1和图2所示，弹性帽120构造为底部敞开的大体筒状结构，阀体100还可以包括底座130，底座130密封弹性帽120的底部且底座130上设置有连通弹性帽120内部的充气接口131，驱动装置与充气接口131相连。
也就是说，腔体1011是由弹性帽120和底座130共同限定出的，底座130上设有与气 泵相连的充气接口131，驱动装置可以向腔体1011内充气以改变腔体1011内的气体压力，或者驱动装置可以向腔体1011内充液以改变腔体1011内的液体压力，进而弹性帽120发生弹性形变以阻隔进口111a和出口111b；驱动装置不工作或者驱动装置将腔体1011内的气体/液体抽出时，弹性帽120可以复原到初始位置，进而壳体110上的进口111a和出口111b得以连通。由此，实现了阀体100的进口111a和出口111b的连通或闭合。
更具体地，底座130和壳体110可以通过螺纹紧固件(例如，螺钉)固定在一起，弹性帽120被夹设在壳体110与底座130之间。如图1所示，底座130上设有朝向壳体110凸出的环形凸起1223，壳体110套设在环形凸起1223上，弹性帽120被夹设在壳体110与环形凸起1223之间。弹性帽120与壳体110之间限定介质流通腔，接口111连通介质流通腔。可以理解的是，介质流通腔即上述的出进口111a与出口111b之间的一个或多个流通通道，底座130与弹性帽120之间限定出腔体1011。
进一步具体地，如图1和图2所示，弹性帽120包括顶壁122和侧壁123，侧壁123的远离顶壁122的一端设有安装部1213，安装部1213朝向侧壁123的外侧延伸，壳体11和环形凸起1223配合夹紧安装部1213。
如图1和图2所示，弹性帽120包括顶壁122和侧壁123，顶壁122的至少一部分形成弹性变形面121。在本发明的具体示例中，弹性变形面121为顶壁122的至少一部分向下凹陷形成。在常态下，由于顶壁122向下凹陷，顶壁122与进口111a之间会间隔开一定的距离，气体或液体可以通过顶壁122与进口111a之间的间隙在进口111a和出口111b之间流动。当腔体1011内的压强增大到一定值时，弹性变形面121会向上凸起以将进口111a封堵，进而阻隔进口111a和出口111b，液体或气体不能在进口111a和出口111b之间流通。
在本发明的一些实施例中，如图1-图3所示，接口111为两组，其中一组接口111用于流通液体，另一组接口111用于流通气体。
也就是说，壳体110上设有两组接口111，例如第一接口和第二接口，第一接口111用于流通液体(例如，水)，第二接口用于流通气体(例如，空气)，第一接口包括进水口104和出水口105，第二接口包括进气口101和排气口102。其中，进气口101和进水口104即为进口111a，排气口102和出水口105即为出口111b。
具体地，如图1-图3所示，进水口104和排气口102置于壳体110的一侧，出水口105与进气口101置于壳体110的另一侧。壳体110构造为底部敞开的大体筒状结构，壳体110包括顶壁部和置于顶壁部外周沿且向下延伸的侧壁部，进水口104和排气口102设置在顶壁部上，进气口101和出水口105设置在侧壁部上。
其中，出水口105位于进气口101的下侧。由此，液体可以在重力的作用下从下方的 出水口105流出，而不会流入倒灌至进气口101中。
当然，可以理解的是，出水口105和进气口101也可以共用一个开口，共用开口既可以作为液体通道的出口111b，又可以作为气体通道的进口111a。
下面参考图1-图3详细描述根据本发明实施例的咖啡机1。
结合图3所示，根据本发明实施例的咖啡机1，包括：锅炉11、阀体100、驱动装置13和酿造腔17。
具体而言，酿造腔17与锅炉11接通，其中连通酿造腔17和锅炉11的管路18可以延伸到锅炉11内的底部。阀体100具有用于流通气体的一组接口111，用于流通气体的接口111包括进气口101和排气口102，进气口101连通锅炉11，排气口102接通外界空气，弹性帽121在隔断进气口101与排气口102的封闭状态和使进气口101与排气口102接通的接通状态之间可转换，弹性帽121常处于接通状态(参见图1)，也就是说弹性帽121常处于使锅炉11接通大气的状态。驱动装置13用于驱动弹性帽121向隔断进气口101与排气口102的封闭状态转换，驱动装置13与锅炉11连通，在弹性帽121处于封闭状态时，驱动装置13可以驱动锅炉11内的水通过管路18流向酿造腔17。
咖啡机1还可以包括加热装置，加热装置用于对锅炉11进行加热，加热装置的至少一部分可以邻近锅炉11设置。
根据本发明实施例的咖啡机1，通过设置阀体100，在锅炉11正常加热过程中，锅炉11与外界空气接通，使得锅炉11内的气压与外界空气大体一致，避免未加热完成的水排入到酿造腔17内；在锅炉11加热完成后，驱动装置13驱动弹性帽121转换至封闭状态，使得锅炉11内的气压升高，将锅炉11内的水压送到酿造腔17内。
本发明简化了咖啡机的结构，使得储咖啡机结构简单、生产方便、成本低、维护方便以及方便操作且稳定性高。
另外，在本发明的一些实施例中，驱动装置13可以为气泵，阀体100通过驱动装置13进行气压换向：驱动装置13不工作的时候锅炉11始终与大气相通，驱动装置13工作时，阀体100在驱动装置13压力作用下换向，关闭锅炉11与大气相通的管路，使锅炉11密封，热水只能从管道18出来，达到酿造咖啡作用，驱动装置13停止工作时阀体100又恢复原状。阀体100与驱动装置13组合有三个关键作用：1、使阀体100换向，酿造咖啡；2、热水出完后，驱动装置13的气体还可以吹干酿造腔17里面残余的水，解决滴漏问题；3、锅炉11里面在加热时始终与大气相通，只有当驱动装置13工作时锅炉11才密封，靠外作用才产生压力，这样解决了锅炉11安全问题。
另外，本发明可以通过驱动阀体100封闭锅炉11，并继续对锅炉加热，通过锅炉内的蒸汽压来驱动锅炉11内的水流向酿造腔17.
为了向锅炉11内添加水，可以将锅炉11设置成具有锅炉盖的形式，从而通过打开和关闭锅炉盖来实现打开或封闭锅炉11的目的，而且在打开锅炉11时可以注入水。另外，还可以通过设置水箱14向锅炉11内供水，例如通过水泵将水箱14内的水输送至锅炉11；或者通过上置水箱14使水箱14内的水在重力作用下进入锅炉11等。下面以设置水箱向锅炉11内注水为例进行说明。
参照图1-图3，在本发明的一些实施例中，咖啡机1还包括水箱14，阀体100还具有用于流通液体的一组接口111，用于流通液体的接口111包括进水口104和出水口105，进水口104与水箱14接通，出水口105与锅炉11接通，弹性帽121在封闭状态隔开进水口104和出水口105，且弹性帽121在接通状态进水口104和出水口105接通。通过水箱14向锅炉11内供水，可以提高锅炉11的密封性能，另外，在壳体110上设置进水口104和出水口105也可以简化咖啡机1的结构，方便生产和控制。
其中，进水口104与排气口102可以重合，使得排气口102通过水箱14接通外界空气，出水口105与进气口101也可以重合，实现锅炉11的进水以及出气。
另外，水箱14也可以通过另外设置的管道来向锅炉11内供水，例如在水箱14和锅炉11之间设置水泵将水箱14内的水泵送到锅炉11内，或者将水箱14置于锅炉11上并设置阀门来控制水箱14向锅炉11内供水。
进一步地，参照图3，水箱14的至少一部分设在锅炉11的上方。方便将水箱14内的水注入到锅炉11内。
优选地，可以将整个水箱14都设置在锅炉11的上方，进一步地，可以将阀体100设置在水箱14的下端所在平面和锅炉11的上端所在平面之间的位置。
参照图3，在本发明的一些实施例中，锅炉11上设有用于检测锅炉11内部的温度的温度传感器15。从而可以实时的了解锅炉11内的温度，以便于在锅炉11内的温度达到预定温度时进入下一步工序，不仅可以提高效率，而且还可以降低能耗。
温度传感器15可以在锅炉11的顶部、底部或侧面。
进一步地，参照图3，锅炉11上设有液位传感器16。通过液位传感器16了解锅炉11内的液位，提高了锅炉11的安全性和稳定性，而且还可以实现定量制热水。
本发明还提出了一种咖啡机的控制方法，所述咖啡机为本发明前述实施例所述的咖啡机，所述方法包括：向所述锅炉内添加适量的水后对锅炉加热，且在对锅炉加热过程中通过阀体使锅炉接通大气；加热完成后，所述驱动装置运行驱动所述阀体转换至封闭状态，并通过驱动装置驱动锅炉内的水通过所述管路流向酿造腔。
根据本发明实施例的咖啡机的控制方法，通过设置阀体，在锅炉正常加热过程中，锅炉与外界空气接通，使得锅炉内的气压与外界空气大体一致，避免未加热完成的水排入到 酿造腔内；在锅炉加热完成后，驱动装置驱动阀体转换至封闭状态，并驱动锅炉内的水通过管路流向酿造腔内。
在本发明的一些实施例中，驱动装置为气泵。
具体而言，结合图1-图3，本发明的咖啡机100工作时：
首先通过水箱14向锅炉11内加水，其中可以通过控制水箱14来实现定量供水；
然后加热锅炉11，此时弹性帽121的弹性变形面121处于向下凹陷的形状，使得水路(进水口104和出水口105之间的通道)接通，气路(进气口101和排气口102之间的通道)接通，加热过程中的蒸汽可以从排气口102排出，锅炉11内的气压不会有较大变化，基本与外界空气的气压相同；
最后，通过温度传感器15检测锅炉11内的温度(例如直接检测水温)，在锅炉11内的水温达到预定温度时，停止加热，启动驱动装置13，在驱动装置13的作用下，弹性帽121的弹性变形面121处于向上凸起的形状，阀体100转换至封闭状态，使锅炉11与外界空气断开，此时驱动装置13工作将会增加锅炉11内的气压，气压的作用将会使锅炉11内的热水排入到酿造腔17内。
停止驱动装置13，弹性变形面121回复至下凹的形状。
结合图1和图2，本发明的阀体100上具有四个接口(进气口101、排气口102、进水口104以及出水口105)形成两组管路，一组通水，一组通气；阀体100内的弹性帽121(例如硅胶帽)可以在外压力作用下鼓起以密封阀体100上方的两个孔，使锅炉呈封闭状态。
水箱14上置，水在重力作用下，通过阀体100流入锅炉11，直到灌满锅炉11；液位传感器16有感应水位作用，感应水位后开始加热，达到设定温度后停止加热；感应到设定温度后，驱动装置13开始工作，驱动装置一端吹向阀体100，弹性帽121在气压下鼓起，密封上方两个孔，另一端吹入锅炉11，此时锅炉11呈封闭状态，锅炉11内的热水流向酿造腔17，达到酿造咖啡效果；咖啡酿造完成后，驱动装置13停止工作，弹性帽121恢复原状，进入下次循环。
本发明的驱动装置可以至少具有如下作用：A、排出锅炉内的水，B、通过阀体密封水箱和通大气管路，C、吹干胶囊。
